Ladies and Gentlemen:

         First Tennessee Capital I, a statutory business trust formed under the

consists of debt securities of the Company (the "Subordinated Debentures"), as
specified in Schedule II to this Agreement. The Designated Securities will be
guaranteed by the Company to the extent set forth in this Agreement with respect
to such Designated Securities (the "Guarantee"). Each of the provisions of the
Standard Provisions is incorporated herein by reference in its entirety, and
shall be deemed to be a part of this Agreement to the same extent as if such
provisions had been set forth in full herein; and each of the representations
and warranties set forth therein shall be deemed to have been made at and as of
the date of this Pricing Agreement, except that each representation and warranty
which refers to the Prospectus in Section 2 of the Standard Provisions shall be
deemed to be a representation or warranty as of the date of the Standard
Provisions in relation to the Prospectus (as therein defined), and also a
representation and warranty as of the date of this Pricing Agreement in relation
to the Prospectus as amended or supplemented relating to the Designated
Securities which are the subject of this Pricing Agreement. Each reference to
the Representatives herein and in the provisions of the Standard Provisions so
incorporated by reference shall be deemed to refer to you. Unless otherwise
defined herein, terms defined in the Standard Provisions are used herein as
therein defined. The Representatives designated to act on behalf of the
Representatives and on behalf of each of the Underwriters of the Designated
Securities pursuant to Section 12 of the Standard Provisions and the address of
the Representatives referred to in such Section 12 are set forth in Schedule II
hereto.

         An amendment to the Initial Registration Statement or a supplement to
the Prospectus, as the case may be, relating to the Designated Securities, in
the form heretofore delivered to you is now proposed to be filed with the
Commission.

         Subject to the terms and conditions set forth herein and in the
Standard Provisions incorporated herein by reference, (a) the Designated Trust
agrees to issue and sell to each of the Underwriters, and each of the
Underwriters agrees, severally and not jointly, to purchase from the Designated
Trust, at the time and place and at the purchase price to the Underwriters set
forth in Schedule II hereto, the number of Firm Designated Securities set forth
opposite the name of such Underwriter in Schedule I hereto and, (b) in the event
and to the extent that the Underwriters shall exercise the election to purchase
Optional Designated Securities, as provided below, the Designated Trust agrees
to issue and sell to each of the Underwriters, and each of the Underwriters
agrees, severally and not jointly, to purchase from the Designated Trust at the
purchase price to the Underwriters set forth in Schedule II hereto that portion
of the number of Optional Designated Securities as to which such election shall
have been exercised.

         The Designated Trust hereby grants to each of the Underwriters the
right to purchase at their election up to the number of Optional Designated
Securities set forth opposite the name of such Underwriter in Schedule I hereto
on the terms referred to in the paragraph above for the sole purpose of covering

                      FIRST TENNESSEE NATIONAL CORPORATION

                               Standard Provisions

                                                               December 17, 1996



         From time to time First Tennessee Capital I, First Tennessee Capital
II, First Tennessee Capital III or First Tennessee Capital IV, each a statutory
business trust formed under the laws of the State of Delaware (each a "Trust"
and collectively, the "Trusts"), and First Tennessee National Corporation, a
Tennessee corporation (the "Company"), as depositor of each trust and as
guarantor, may enter into one or more Pricing Agreements (each a "Pricing
Agreement") in the form of Annex I hereto, with such additions and deletions as
the parties thereto may determine, pursuant to which, and subject to the terms
and conditions stated herein and therein, the Trust identified in the applicable
Pricing Agreement (such Trust being the "Designated Trust" with respect to such
Pricing Agreement) will propose to issue and sell to the firms named in Schedule
I to the applicable Pricing Agreement (such firms constituting the
"Underwriters" with respect to such Pricing Agreement and the securities
specified therein) certain of its preferred securities (the "Securities")
representing undivided beneficial interests in the assets of the Designated
Trust. The Securities specified in such Pricing Agreement are referred to as the
"Firm Designated Securities" with respect to such Pricing Agreement. If
specified in such Pricing Agreement, the Designated Trust may grant the
Underwriters the right to purchase at their election an additional number of
Securities, specified as provided in such Pricing Agreement as provided in
Section 3 hereof (the "Optional Designated Securities"). The Firm Designated
Securities and any Optional Designated Securities are collectively called the
"Designated Securities." The proceeds of the sale of the Designated Securities
to the public and of common securities of the Designated Trust (the "Common
Securities") to the Company concurrently with the sale of the Designated
Securities are to be invested in junior subordinated deferrable interest
debentures of the Company (the "Subordinated Debentures") identified in the
Pricing Agreement with respect to such Designated Securities (with respect to
such Pricing Agreement, the "Designated Subordinated Debentures"), to be issued
pursuant to a junior subordinated indenture to be dated as of December 30, 1996
(the "Indenture") between the Company and The Bank of New York, as trustee (the
"Debenture Trustee"). The Designated Securities may be exchangeable into
Designated Subordinated Debentures, as specified in Schedule II to such Pricing
Agreement. The Designated Securities will be guaranteed by the Company to the
extent set forth in the Pricing Agreement with respect to such Designated
Securities (the "Designated Guarantee") (all such Designated Guarantees
together, the "Guarantees").

         The terms and rights of any particular issuance of Designated
Securities shall be as specified in the Pricing Agreement relating thereto and
in or pursuant to the amended and restated trust agreement identified in such
Pricing Agreement (with respect to such Pricing Agreement, the "Trust
Agreement"). The standard provisions set forth herein (these "Standard
Provisions") may be incorporated by reference in any such Pricing Agreement. The
Pricing Agreement, including these
<PAGE>   9
                                                                               2



Standard Provisions to the extent incorporated therein by reference, is herein
sometimes referred to as this "Agreement".

         1. Particular sales of Designated Securities may be made from time to
time to the Underwriters of such Designated Securities, for whom the firms
designated as representatives of the Underwriters of such Designated Securities
in the Pricing Agreement relating thereto will act as representatives (the
"Representatives"). The term "Representatives" also refers to a single firm
acting as sole representative of the Underwriters and to Underwriters who act
without any firm being designated as their representative. These Standard
Provisions shall not be construed as an obligation of any Trust to sell any of
the Securities or as an obligation of any of the Underwriters to purchase any of
the Securities. The obligation of any Trust to issue and sell any of the
Securities and the obligation of any of the Underwriters to purchase any of the
Securities shall be evidenced by the Pricing Agreement with respect to the
Designated Securities specified therein. Each Pricing Agreement shall specify
the aggregate number of the Firm Designated Securities, the maximum number of
Optional Designated Securities, if any, the initial public offering price of
such Firm and Optional Designated Securities or the manner of determining such
price, the terms of the Designated Securities, including the terms on which and
terms of the securities into which the Designated Securities will be
exchangeable, the purchase price to the Underwriters of such Designated
Securities, the names of the Underwriters of such Designated Securities, the
names of the Representatives of such Underwriters, the number of such Designated
Securities to be purchased by each Underwriter and the commission, if any,
payable to the Underwriters with respect thereto and shall set forth the date,
time and manner of delivery of such Firm Designated Securities and Optional
Designated Securities, if any, and payment therefor. The Pricing Agreement shall
also specify (to the extent not set forth in the registration statement and
prospectus with respect thereto) the terms of such Designated Securities. A
Pricing Agreement shall be in the form of an executed writing (which may be in
counterparts), and may be evidenced by an exchange of telegraphic communications
or any other rapid transmission device designed to produce a written record of
communications transmitted. The standard provisions set forth herein will be
incorporated by reference in any Pricing Agreement. The obligations of the
Underwriters under this Agreement shall be several and not joint.

         2. Each of the Designated Trust and the Company, jointly and severally,
represents and warrants to, and agrees with, each of the Underwriters that:

                  (a) A registration statement on Form S-3 (File No. 333-17457)

         by reference therein has heretofore been filed, or transmitted for
         filing, with the Commission (other than prospectuses filed pursuant to
         Rule 424(b) of the rules and regulations of the Commission under the
         Act, each in the form heretofore delivered to the Representatives); and
         no stop order suspending the effectiveness of the Initial Registration

         Registration Statement; and any reference to the Prospectus as amended
         or supplemented shall be deemed to refer to the Prospectus as amended
         or supplemented in relation to the applicable Designated Securities in

         material fact or omit to state a material fact required to be stated
         therein or necessary to make the statements therein not misleading;
         provided, however, that this representation and warranty shall not
         apply to any statements or omissions made in reliance upon and in
         conformity with information furnished in writing to the Designated
         Trust or the Company by an Underwriter of Designated Securities through
         the Representatives expressly for use in the Prospectus as amended or
         supplemented relating to such Securities;

                  (d) The financial statements (including the related notes and
         supporting schedules) incorporated in the Prospectus present fairly the
         financial condition and results of operations of the entities purported
         to be shown thereby, at the dates and for the periods indicated, and
         have been prepared in conformity with generally accepted accounting
         principles applied on a consistent basis throughout the periods
         indicated;

                  (e) Neither the Company nor any of its subsidiaries has
         sustained since the date of the latest audited financial statements
         incorporated by reference in the Prospectus any material loss or
         interference with its business from fire, explosion, flood or other
         calamity, whether or not covered by insurance, or from any labor
         dispute or court or governmental action, order or decree, otherwise
         than as set forth or contemplated in the Prospectus; and, since the
         respective dates as of which information is given or incorporated by
         reference in the Registration Statement and the Prospectus, there has
         not been any change in the capital stock (other than relating to
         issuances pursuant to stock benefit plans and dividend reinvestment
         plans and acquisitions of capital stock pursuant to announced share
         repurchase programs) or long-term debt of the Company or any of its
         subsidiaries or any material adverse change, or any development
         involving a prospective material adverse change, in or affecting the
         general affairs, management, financial position, stockholders' equity
         or results of operations of the Company and its subsidiaries, taken as
         a whole, otherwise than as set forth or contemplated in the Prospectus;

                  (f) The Designated Trust has been duly created and is validly
         existing as a business trust in good standing under the laws of the
         State of Delaware, with power and authority to own, lease and operate
         its properties and conduct its business as described in the Prospectus
         and has conducted and will conduct no business other than the
         transactions contemplated by the Prospectus; the Company has been duly
         incorporated and is validly existing as a corporation in good standing

         (other than where the failure to be so qualified or in good standing
         would not have a material adverse effect on the Company and its
         subsidiaries taken as a whole);

                  (g) The compliance by the Company and the Designated Trust
         with all of the provisions of this Agreement and the consummation of

         in a breach or violation of any of the terms or provisions of, or
         constitute a default under, any indenture, mortgage, deed of trust,
         loan agreement or other agreement or instrument to which the Company,
         the Designated Trust or any of their subsidiaries is a party or by
         which the Company, the Designated Trust or any of their subsidiaries is
         bound or to which any of the property or assets of the Company, the
         Designated Trust or any of their subsidiaries is subject other than
         such conflicts, breaches, violations or defaults which individually or
         on a cumulative basis would not have a material adverse effect on the
         Company and its subsidiaries taken as a whole, nor will such action
         result in any violation of the provisions of the Restated Charter or
         By-laws, each as amended, of the Company, or any statute or any order,
         rule or regulation of any court or governmental agency or body having
         jurisdiction over the Company or the Designated Trust; and no consent,

         with any such court or governmental agency or body is required for sale
         of the Designated Securities or the Designated Subordinated Debentures
         or the consummation by the Company or the Designated Trust of the
         transactions contemplated by this Agreement, except the registration
         under the Act of the Designated Securities and the Designated
         Subordinated Debentures and such consents, approvals, authorizations,
         registrations or qualifications as may be required under state
         securities or Blue Sky laws in connection with the purchase and
         distribution of the Designated Securities by the Underwriters;

                  (h) The Designated Guarantee, the Trust Agreement for the
         Designated Trust, the Designated Subordinated Debentures and the
         Indenture (the Designated Guarantee, such Trust Agreement, the
         Designated Subordinated Debentures and the Indenture being collectively
         referred to as the "Company Agreements") have each been duly authorized
         by the Company and when validly executed and delivered by the Company
         and, in the case of the Guarantee, by the Guarantee Trustee (as defined
         in the Guarantee), in the case of the Trust Agreement, by the Trustees
         (as defined in the Trust Agreement) and, in the case of the Indenture,
         by the Debenture Trustee, and, in the case of the Designated
         Subordinated Debentures, when validly issued by the Company and duly
         authenticated and delivered by the Debenture Trustee against payment
         therefore as contemplated by the Company Agreements, will constitute
         valid and legally binding obligations of the Company, enforceable in
         accordance with their respective terms, subject to bankruptcy,
         insolvency, reorganization, moratorium and other similar laws relating
         to or affecting creditors' rights generally, general equitable
         principles (regardless of whether considered in a proceeding in equity
         or at law) and an implied covenant of good faith and fair dealing; the
         Trust Agreement, the Indenture and the Designated Guarantee have each
         been duly qualified under the Trust Indenture Act; the Designated
         Subordinated Debentures are entitled to the benefits of the Indenture;

         filed as exhibits to the Registration Statement, will conform in all
         material respects to the descriptions thereof in the Prospectus as
         amended or supplemented with respect to the Designated Securities to
         which they relate; and

                  (i) The Common Securities and Designated Securities have been
         duly authorized by the Designated Trust and upon issuance and delivery
         and payment therefor in the manner described herein, will be duly
         authorized, validly issued, fully paid and non-assessable and will
         conform to their respective descriptions in the Prospectus;

                  (j) Other than as set forth in the Prospectus, there are no
         legal or governmental proceedings pending to which the Company or any
         of its subsidiaries is a party or to which any property of the Company
         or any of its subsidiaries is subject, as to which there exists a
         reasonably likelihood of an adverse determination which is reasonably
         likely, individually or on a cumulative basis, when resolved, to have a
         material adverse effect on the consolidated financial position,
         shareholders' equity or results of operations of the Company and its
         subsidiaries, taken as a whole, and, to the best of the Company's
         knowledge, no such proceedings are threatened;

                  (k) The Company is not in violation of its restated charter or
         by-laws, in each case as amended; and neither the Company nor any of
         its subsidiaries is in default in the performance or observance of any
         material obligation, covenant or condition contained in any indenture,
         mortgage, deed of trust, loan agreement, lease or other agreement or
         instrument to which it is a party or by which it or any of its
         properties may be bound other than such defaults which individually or
         on a cumulative basis would not have a material adverse effect on the
         financial condition, operating results, business or prospects of the
         Company and its subsidiaries taken as a whole or on the issue and sale
         of the Designated Securities or consummation of the transactions
         contemplated thereby;
<PAGE>   13
                                                                               6



                  (l) Neither the Company nor the Designated Trust is an
         "investment company" within the meaning of such term under the
         Investment Company Act of 1940 and the rules and regulations of the
         Commission thereunder;

                  (m) The Company is duly registered as a bank holding company
         under the Bank Holding Company Act of 1956, as amended (the "BHC Act");

                  (n) The Company and each of its subsidiaries are in compliance
         in all material respects with all laws administered by and regulations
         of and any federal or state bank regulatory authority with jurisdiction
         over the Company or any of its subsidiaries (the "Bank Regulatory
         Authorities"), other than where such failures to comply would not have
         a material adverse effect on the Company and its subsidiaries, taken as
         a whole. Neither the Company nor any of its subsidiaries is a party to
         any written agreement or memorandum of understanding with, or a party
         to any commitment letter or similar undertaking to, or is subject to
         any order or directive by, or is a recipient of any extraordinary
         supervisory letter from, or has adopted any board resolutions at the
         request of, any Bank Regulatory Authority which restricts materially
         the conduct of its business, or in any manner relates to its capital
         adequacy, its credit policies or its management, nor have any of them
         been advised by any Bank Regulatory Authority that it is contemplating
         issuing or requesting (or is considering the appropriateness of issuing
         or requesting) any such order, decree, agreement, memorandum of
         understanding, extraordinary supervisory letter, commitment letter or
         similar submission, or any such board resolutions; and

                  (o) The Pricing Agreement with respect to the Designated
         Securities (incorporating these Standard Provisions) and this Agreement
         have been duly authorized, executed and delivered by the Company and
         the Designated Trust.

         3. Upon the execution of the Pricing Agreement applicable to any
Designated Securities and authorization by the Representatives of the release of
the Firm Designated Securities, the several Underwriters propose to offer the
Firm Designated Securities for sale upon the terms and conditions set forth in
the Prospectus as amended or supplemented.

         The Designated Trust may specify in the Pricing Agreement applicable to
any Designated Securities that the Designated Trust thereby grants to the
Underwriters the right (an "Over-allotment Option") to purchase at their
election up to the number of Optional Designated Securities set forth in such
Pricing Agreement, on the terms set forth in the paragraph above, for the sole
purpose of covering over-allotments in the sale of the Firm Designated
Securities. Any such election to purchase Optional Designated Securities may be
exercised by written notice from the Representatives to the Designated Trust and
the Company, given within a period specified in the Pricing Agreement, setting
forth the aggregate number of Optional Designated Securities to be purchased and
the date on which such Optional Designated Securities are to be delivered, as
determined by the Representatives but in no event earlier than the First Time of
Delivery (as defined in Section 4 hereof) or, unless the Representatives, the
Designated Trust and the Company otherwise agree in writing, earlier than or
later than the respective number of business days after the date of such notice
set forth in such Pricing Agreement.

         The number of Optional Designated Securities to be added to the number
of Firm Designated Securities to be purchased by each Underwriter as set forth
in Schedule I to the Pricing Agreement applicable to such Designated Securities
shall be, in each case, the number of Optional Designated Securities which the
Designated Trust and the Company have been advised by the Representatives have
been attributed to such Underwriter; provided that, if the Designated Trust and
the Company have not been so advised, the number of Optional Designated
Securities to be so added shall be, in each case, that proportion of Optional

number of Firm Designated Securities (rounded as the Representatives may
determine to the nearest 100 securities). The total number of Designated
Securities to be purchased by all the Underwriters pursuant to such Pricing
Agreement shall be the aggregate number of Firm Designated Securities set forth
in Schedule I to such Pricing Agreement plus the aggregate number of Optional
Designated Securities which the Underwriters elect to purchase.

         As compensation to the Underwriters of the Designated Securities for
their commitments hereunder and under the Pricing Agreement, and in view of the
fact that the proceeds of the sale of the Designated Securities will be used by
the Designated Trust to purchase the Designated Subordinated Debentures of the
Company, the Company agrees to pay at each Time of Delivery to the
Representatives, for the accounts of the several Underwriters, the amount set
forth in the Pricing Agreement per preferred security for the Designated
Securities to be delivered at each Time of Delivery.

         4. Certificates for the Firm Designated Securities and the Optional
Designated Securities to be purchased by each Underwriter pursuant to the
Pricing Agreement relating thereto, in the form specified in such Pricing
Agreement, and in such authorized denominations and registered in such names as
the Representatives may request upon at least forty-eight hours' prior notice to
the Designated Trust and the Company, shall be delivered by or on behalf of the
Designated Trust to the Representatives for the account of such Underwriter,
against payment by such Underwriter or on its behalf of the purchase price
therefor by wire transfer of Federal (same day) Funds to an account designated
by the Designated Trust, (i) with respect to the Firm Designated Securities, all
in the manner and at the place and time and date specified in such Pricing
Agreement or at such other place and time and date as the Representatives, the
Designated Trust and the Company may agree upon in writing, such time and date
being herein called the "First Time of Delivery" and (ii) with respect to the
Optional Designated Securities, if any, in the manner and at the time and date

the Designated Trust and the Company may agree upon in writing, such time and
date, if not the First Time of Delivery, herein called the "Second Time of

         or supplement (other than an amendment by reason of filing a report

         Designated Securities) and not to file any such proposed amendment or
         supplement to which the Representatives reasonably object; to advise
         the Representatives promptly of any such amendment or supplement after
         any Time of Delivery for the Designated Securities and furnish the

         when any such amendment to the Registration Statement has been filed or
         becomes effective or any such supplement to the Prospectus or any

         of the qualification of the Designated Securities or the Designated
         Subordinated Debentures for offering or sale in any jurisdiction, of
         the initiation or threatening of any proceeding for any such purpose,

         sale under the securities laws of such jurisdictions as the
         Representatives may request and to comply with such laws so as to
         permit the continuance of sales and dealings therein in such
         jurisdictions for as long as may be necessary to complete the
         distribution of such Designated Securities, provided that in connection
         therewith neither the Designated Trust nor the Company shall be
         required to qualify as a foreign corporation or to file a general
         consent to service of process in any jurisdiction;

         expiration of nine months after the time of issue of the Prospectus in
         connection with the offering or sale of the Designated Securities or
         the Designated Subordinated Debentures and if at such time any event
         shall have occurred as a result of which the Prospectus as then amended
         or supplemented would include an untrue statement of a material fact or
         omit to state any material fact necessary in order to make the
         statements therein, in the light of the circumstances under which they
         were made when such Prospectus is delivered, not misleading, or, if for
         any other reason it shall be necessary during such same period to amend
         or supplement the Prospectus or to file under the Exchange Act any
         document incorporated by reference in the Prospectus in order to comply
         with the Act, the Exchange Act or the Trust Indenture Act, to notify
         the Representatives and upon their request to file such document and to
         prepare and furnish without charge to each Underwriter and to any
         dealer in securities as many copies as the Representatives may from
         time to time reasonably request of an amended Prospectus or a
         supplement to the Prospectus which will correct such statement or
         omission or effect such compliance.

                  (d) In the case of the Company, to make generally available to
         its security holders as soon as practicable, but in any event not later

         regulations of the Commission thereunder (including, at the option of
         the Company, Rule 158);

                  (e) During the period beginning from the date of the Pricing

                  violations or defaults which individually or on a cumulative
                  basis would not have a material adverse effect on the
                  financial condition, operating results or prospects of the
                  Company and its subsidiaries taken as a whole; nor will such
                  actions by the Company result in any violation of any statute
                  or any order, rule or regulation known to such counsel of any
                  court or governmental agency or body having jurisdiction over
                  the Company or its properties; provided that for purposes of
                  this opinion such counsel need not express any opinion with
                  respect to State securities laws, antifraud laws, fraudulent
                  transfer laws or antitrust laws;

                       (xii) All consents, approvals, authorizations, orders,
                  registrations or qualifications with any Tennessee
                  governmental agency or body required for the issuance and sale
                  of the Designated Securities being delivered at such Time of
                  Delivery or the issuance of the Designated Guarantee and
                  Designated Subordinated Debentures or the consummation by the
                  Designated Trust or the Company of the transactions
                  contemplated by this agreement have been obtained, except such
                  as have been obtained under the Act and the Trust Indenture
                  Act and such consents, approvals, authorizations,
                  registrations or qualifications as may be required under state
                  securities or Blue Sky laws in connection with the purchase
                  and distribution of the Designated Securities by the
                  Underwriters or the issuance of the Designated Guarantee and
                  Designated Subordinated Debentures by the Company;

                      (xiii) The Registration Statement and the Prospectus as
                  amended or supplemented, and any further amendments and
                  supplements thereto made by the Designated Trust or the
                  Company prior to such Time of Delivery (other than the
                  financial statements and related schedules and other financial
                  and statistical data therein and the Form T-1 Statements of
                  Eligibility and Qualification of the Trustees, as to which
                  such counsel need express no opinion), appeared on their face
                  to be appropriately responsive in all material respects with
                  the requirements of the Act and the rules and regulations
                  thereunder; although they have not independently verified and
                  do not assume any responsibility for the accuracy,
                  completeness or fairness of the statements contained in the
                  Registration Statement or the Prospectus, such counsel has no
                  reason to believe that, as of its effective date, the
                  Registration Statement or any further amendment thereto made
                  by the Designated Trust or the Company prior to such Time of

                  omitted to state a material fact required to be stated therein
                  or necessary to make the statements therein not misleading or
                  that, as of its date, the Prospectus as amended or
                  supplemented or any further amendment or supplement thereto
                  made by the Designated Trust or the Company prior to such Time

                  not know of any contracts or other documents of a character
                  required to be filed as an exhibit to the Registration
                  Statement or required to be incorporated by reference into the

                  (d) Special Delaware Counsel to the Designated Trust and the
         Company satisfactory to the Representatives, shall have furnished to
         you, the Company and the Designated Trust their written opinion, dated

                  validly existing in good standing as a business trust under
                  the Delaware Business Trust Act, and all filings required
                  under the laws of the State of Delaware with respect to the
                  creation and valid existence of the Designated Trust as a
                  business trust have been made;

                        (ii) Under the Delaware Business Trust Act and the Trust
                  Agreement, the Designated Trust has the power and authority to
                  own property and conduct its business, all as described in the
                  Prospectus;

                       (iii) The Trust Agreement constitutes a valid and legally
                  binding obligation of the Company and the Trustees,
                  enforceable against the Company and the Trustees, in
                  accordance with its terms, subject, as to enforcement, to
                  bankruptcy, insolvency, fraudulent transfer, reorganization,
                  moratorium and similar laws of general applicability relating
                  to or affecting creditors' rights and to general equity
                  principles;

                        (iv) Under the Delaware Business Trust Act and the Trust
                  Agreement, the Designated Trust has the power and authority to
                  (a) execute and deliver, and to perform its obligations under
                  this Agreement and the Pricing Agreement and (b) issue and
                  perform its obligations under the Designated Securities and
                  the Common Securities of the Designated Trust;

                         (v) Under the Delaware Business Trust Act and the Trust
                  Agreement, the execution and delivery by the Designated Trust
                  of this Agreement and the Pricing Agreement, and the
                  performance by the Designated Trust of its obligations
                  thereunder and thereunder, have been duly authorized by all
                  necessary action on the part of the Designated Trust;

                        (vi) The Designated Securities have been duly authorized
                  by the Trust Agreement and are duly and validly issued and,
                  subject to the qualifications set forth herein, fully paid and
                  non-assessable beneficial interests in the Designated Trust
                  and are entitled to the benefits provided by the Trust
                  Agreement; the holders of the Designated Securities (the
                  "Securityholders"), as beneficial owners of the Designated
                  Trust, will be entitled to the same limitation of personal
                  liability extended to stockholders of private corporations for
                  profit organized under the General Corporation Law of the
                  State of Delaware; provided that such counsel may note that
                  the Securityholders may be obligated, pursuant to the Trust
                  Agreement, to (a) provide indemnity and/or security in
                  connection with and pay taxes or governmental charges arising
                  from transfers or exchanges of Securities Certificates and the
                  issuance of replacement Securities Certificates and (b)
                  provide security and indemnity in connection with requests of

                  exercise its rights and remedies under the Trust Agreement;

                       (vii) The Common Securities of the Designated Trust have
                  been duly authorized by the Trust Agreement and are validly
                  issued and represent beneficial interests in the Designated
                  Trust;

                      (viii) Under the Delaware Business Trust Act and the Trust
                  Agreement, the issuance of the Designated Securities and the
                  Common Securities of the Designated Trust is not subject to
                  preemptive rights;

                        (ix) The issuance and sale by the Designated Trust of
                  Designated Securities and the Common Securities of the
                  Designated Trust, the execution, delivery and performance by
                  the Designated Trust of this Agreement and the Pricing
                  Agreement, the consummation by the Designated Trust of the
                  transactions contemplated thereby and compliance by the
                  Designated Trust with its obligations thereunder will not
                  violate (a) any of the provisions of the Certificate of Trust
                  of the Designated Trust or the Trust Agreement, or (b) any
                  applicable Delaware law or administrative regulation;

                         (x) Assuming that the Designated Trust derives no
                  income from or connected with services provided within the
                  State of Delaware and has no assets, activities (other than
                  maintaining the Delaware Trustee and the filing of documents
                  with the Secretary of State of the State of Delaware) or
                  employees in the State of Delaware, no authorization,
                  approval, consent or order of any Delaware court or
                  governmental authority or agency is required to be obtained by
                  the Designated Trust solely in connection with the issuance
                  and sale of the Designated Securities and the Common
                  Securities of the Designated Trust. (In rendering the opinion
                  expressed in this paragraph (x), such counsel need express no
                  opinion concerning the securities laws of the State of
                  Delaware.); and

                        (xi) Assuming that the Designated Trust derives no
                  income from or connected with services provided within the
                  State of Delaware and has no assets, activities (other than
                  maintaining the Delaware Trustee and the filing of documents
                  with the Secretary of State of the State of Delaware) or
                  employees in the State of Delaware, the Securityholders (other
                  than those holders of the Securities who reside or are
                  domiciled in the State of Delaware) will have no liability for
                  income taxes imposed by the State of Delaware solely as a
                  result of their participation in the Designated Trust, and the
                  Designated Trust will not be liable for any income tax imposed
                  by the State of Delaware.

                  (e) Tax counsel for the Designated Trust and the Company
         satisfactory to the Representatives shall have furnished to you their
         written opinion, dated the respective Time of Delivery, in form and
         substance satisfactory to you, to the effect that such firm confirms
         its opinion set forth in the Prospectus under the captions "Certain
         Federal Income Tax Consequences", "Risk Factors-Option to Defer
         Interest Payment; Tax Consequences; Market Price Consequence", and
         "Risk Factors-Possible Tax Law Changes Affecting Series A QUIPS";

                  (f) On the date of the Pricing Agreement for such Designated
         Securities at a time prior to the execution of the Pricing Agreement
         with respect to the Designated Securities (if so provided in the
         Pricing Agreement) and at each Time of Delivery for such Designated
         Securities, the independent accountants of the Company who have
         certified the financial statements of the Company and its subsidiaries
         included or incorporated by reference in the Registration Statement
         shall have furnished to the Representatives a letter, dated the
         effective date of the Registration Statement or the date of the most
         recent report filed with the
<PAGE>   22
                                                                              15



         Commission containing financial statements and incorporated by
         reference in the Registration Statement, if the date of such report is
         later than such effective date, and a letter dated such Time of
         Delivery, respectively, to the effect set forth in Annex II hereto, and
         with respect to such letter dated such Time of Delivery, as to such
         other matters as the Representatives may reasonably request and in form
         and substance satisfactory to the Representatives;

                  (g) Neither the Company nor any of its subsidiaries shall have
         sustained since the date of the latest audited financial statements
         incorporated by reference in the Prospectus any (i) loss or
         interference with its business from fire, explosion, flood or other
         calamity, whether or not covered by insurance, or from any labor
         dispute or court or governmental action, order or decree, otherwise
         than as set fort or contemplated in the Prospectus, and (ii) since the
         respective dates as of which information is given in the Prospectus
         there shall not have been any change in the capital stock (other than
         relating to issuances pursuant to stock benefit plans and dividend
         reinvestment plans and acquisitions of capital stock pursuant to
         announced share repurchase programs) or long-term debt of the Company
         or any of its subsidiaries or any change, or any development involving
         a prospective change, in or affecting the general affairs, management,
         financial position, stockholders' equity or results of operations of
         the Company and its subsidiaries taken as a whole, otherwise than as
         set forth or contemplated in the Prospectus, the effect of which, in
         any such case described in Clause (i) or (ii), is in the judgment of
         the Representatives so material and adverse as to make it impracticable
         or inadvisable to proceed with the public offering or the delivery of
         the Designated Security on the terms and in the manner contemplated in
         the Prospectus.

                  (h) On or after the date hereof (i) no downgrading shall have
         occurred in the rating accorded the Company's debt securities by any
         "nationally recognized statistical rating organization", as that term
         is defined by the Commission for purposes of Rule 436(g)(2) under the
         Act, and (ii) no such organization shall have publicly announced that
         it has under surveillance or review, with possible negative
         implications, its rating of any of the Company's debt securities;

                  (i) On or after the date hereof there shall not have occurred
         any of the following: (i) a suspension or material limitation in
         trading in securities generally on the Nasdaq National Market System;
         (ii) a suspension or material limitation in trading in the Company's
         securities or the Nasdaq National Market System; (iii) a general
         moratorium on commercial banking activities declared by either Federal
         or New York State authorities; or (iv) the outbreak or escalation of
         hostilities involving the United States or the declaration by the
         United States of a national emergency or war, if the effect of any such
         event specified in this Clause (iv) in the judgment of the
         Representatives makes it impracticable or inadvisable to proceed with
         the public offering or the delivery of the Designated Securities on the
         terms and in the manner contemplated in the Prospectus;

                  (j) If so provided in the Pricing Agreement, the Designated
         Securities at each Time of Delivery shall have been duly approved for
         listing subject to notice of issuance on the Nasdaq National Market
         System;

                  (k) The Company shall have complied with the provisions of
         Section 5(c) hereof with respect to the furnishing of prospectuses on
         the New York Business Day next succeeding the date of the Pricing
         Agreement for such Designated Securities; and

                  (l) The Designated Trust and the Company shall have furnished
         or caused to be furnished to the Representatives at each Time of
         Delivery for the Designated Securities certificates of officers of the
         Designated Trust and the Company satisfactory to the Representatives as
         to the accuracy of the representations and warranties of the Designated
         Trust and the Company herein at and as of such Time of Delivery, as to
         the performance by

                                                                              16



         the Designated Trust and the Company of all of its obligations
         hereunder to be performed at or prior to such Time of Delivery, as to
         the matters set forth in subsections (a) and (h) of this Section and as
         to such other matters as the Representatives may reasonably request (in
         each case to the best of such officer's knowledge after reasonable
         investigation).

         8. (a) The Designated Trust and the Company will indemnify and hold
harmless each Underwriter against any losses, claims, damages or liabilities,
joint or several, to which such Underwriter may become subject, under the Act or
otherwise, insofar as such losses, claims, damages or liabilities (or actions in
respect thereof) arise out of or are based upon an untrue statement or alleged
untrue statement of a material fact contained in any Preliminary Prospectus, the
Registration Statement or the Prospectus, or any amendment or supplement
thereto, or arise out of or are based upon the omission or alleged omission to
state therein a material fact required to be stated therein or necessary to make
the statements therein not misleading, and will reimburse each Underwriter for
any legal or other expenses reasonably incurred by such Underwriter in
connection with investigating or defending any such action or claim as such
expenses are incurred; provided, however, that the Company and the Designated
Trust shall not be liable in any such case to the extent that any such loss,
claim, damage or liability arises out of or is based upon an untrue statement or
alleged untrue statement or omission or alleged omission made in any Preliminary
Prospectus, the Registration Statement or the Prospectus or any such amendment
or supplement thereto in reliance upon and in conformity with written
information furnished to the Company or the Designated Trust by any Underwriter,
expressly for use therein.

                  (b) Each Underwriter will indemnify and hold harmless the
Designated Trust and the Company against any losses, claims, damages or
liabilities to which the Designated Trust or the Company may become subject,
under the Act or otherwise, insofar as such losses, claims, damages or
liabilities (or actions in respect thereof) arise out of or are based upon an
untrue statement or alleged untrue statement of a material fact contained in any
Preliminary Prospectus, the Registration Statement or the Prospectus, or any
amendment or supplement thereto, or arise out of or are based upon the omission
or alleged omission to state therein a material fact required to be stated
therein or necessary to make the statements therein not misleading, in each case
to the extent, but only to the extent, that such untrue statement or alleged
untrue statement or omission or alleged omission was made in any Preliminary
Prospectus, the Registration Statement or the Prospectus or any such amendment
or supplement thereto in reliance upon and in conformity with written
information furnished to the Company or the Designated Trust by such
Underwriter, expressly for use therein; and will reimburse the Company and the
Designated Trust for any legal or other expenses reasonably incurred by the
Company or the Designated Trust in connection with investigating or defending
any such action or claim as such expenses are incurred.

                  (c) Promptly after receipt by an indemnified party under
subsection (a) or (b) above of notice of the commencement of any action, such
indemnified party shall, if a claim in respect thereof is to be made against the
indemnifying party under such subsection, notify the indemnifying party in
writing of the commencement thereof; but the omissions so to notify the
indemnifying party shall not relieve it from any liability which it may have to
any indemnified party otherwise than under such subsection. In case any such
action shall be brought against any indemnified party and it shall notify the
indemnifying party of the commencement thereof, the indemnifying party shall be
entitled to participate therein and, to the extent that it shall wish, jointly
with any other indemnifying party similarly notified, to assume the defense
thereof, with counsel satisfactory to such indemnified party (who shall not,
except with the consent of the indemnified party, be counsel to the indemnifying
party), and, after notice from the indemnifying party to such indemnified party
of its election so to assume the defense thereof, the indemnifying party shall
not be liable to such indemnified party under such subsection for any legal
expenses of other counsel or any other expenses, in each case subsequently
incurred by such indemnified party, in connection with the defense thereof other
than reasonable costs of investigation. No indemnifying party shall, without the
written consent of the indemnified party, effect the settlement or compromise
of, or consent to the entry of any judgment with respect to, any pending
<PAGE>   24
                                                                              17



or threatened action or claim in respect of which indemnification or
contribution may be sought hereunder (whether or not the indemnified party is an
actual or potential party to such action or claim) unless such settlement,
compromise or judgment (i) includes an unconditional release of the indemnified
party from all liability arising out of such action or claim and (ii) does not
include a statement as to or an admission of fault, culpability or a failure to
act, by or on behalf of any indemnified party.

                  (d) If the indemnification provided for in this Section 8 is
unavailable to or insufficient to hold harmless an indemnified party under
subsection (a) or (b) above in respect of any losses, claims, damages or
liabilities (or actions in respect thereof) referred to therein, then each
indemnifying party shall contribute to the amount paid or payable by such
indemnified party as a result of such losses, claims, damages or liabilities (or
actions in respect thereof) in such proportion as is appropriate to reflect the
relative benefits received by the Designated Trust and the Company on the one
hand and the Underwriters on the other hand from the offering of the Designated
Securities. If, however, the allocation provided by the immediately preceding
sentence is not permitted by applicable law or if the indemnified party failed
to give the notice required under subsection (c) above, then each indemnifying
party shall contribute to such amount paid or payable by such indemnified party
in such proportion as is appropriate to reflect not only such relative benefits
but also the relative fault of the Company and the Designated Trust on the one
hand and the Underwriters on the other hand in connection with the statements or
omissions which resulted in such losses, claims, damages or liabilities (or
actions in respect thereof), as well as any other relevant equitable
considerations. The relative benefits received by the Company and the Designated
Trust on the one hand and the Underwriters on the other hand shall be deemed to
be in the same proportion as the total net proceeds from the offering (before
deducting expenses) received by the Company and the Designated Trust bear to the
total underwriting discounts and commissions received by the Underwriters. The
relative fault shall be determined by reference to, among other things, whether
the untrue or alleged untrue statement of a material fact or the omission or
alleged omission to state a material fact relates to information supplied by the
Company or the Designated Trust on the one hand or the Underwriters on the other
and the parties' relative intent, knowledge, access to information and
opportunity to correct or prevent such statement or omission. The Company, the
Designated Trust and the Underwriters agree that it would not be just and
equitable if contributions pursuant to this subsection (d) were determined by
pro rata allocation (even if the Underwriters were treated as one entity for
such purpose) or by any other method of allocation which does not take account
of the equitable considerations referred to above in this subsection (d). The
amount paid or payable by an indemnified party as a result of the losses,
claims, damages or liabilities (or actions in respect thereof)referred to above
in this subsection (d) shall be deemed to include any legal or other expenses
reasonably incurred by such indemnified party in connection with investigating
or defending any such action or claim. Notwithstanding the provisions of this
subsection (d), no Underwriter shall be required to contribute any amount in
excess of the amount by which the total price at which the Designated Securities
underwritten by it and distributed to the public were offered to the public
exceeds the amount of any damages which such Underwriter has otherwise been
required to pay by reason of such untrue or alleged untrue statement or omission
or alleged omission. No person guilty of fraudulent misrepresentation (within
the meaning of Section 11(f) of the Act) shall be entitled to contribution from
any person who was not guilty of such fraudulent misrepresentation. The
Underwriters' obligations in this subsection (d) to contribute are several in
proportion to their respective underwriting obligations and not joint.

                  (e) The obligation of the Company and the Designated Trust
under this Section 8 shall be in addition to any liability which the Company and
the Designated Trust may otherwise have and shall extend, upon the same terms
and conditions, to each person, if any, who controls any Underwriter within the
meaning of the Act; and the obligations of the Underwriters under this Section 8
shall be in addition to any liability which the respective Underwriters may
otherwise have and shall extend, upon the same terms and conditions, to each
officer and director of the Company and to each person, if any, who controls the
Company or the Designated Trust within the meaning of the Act.

         9. If, at the Time of Delivery, any one or more of the Underwriters
shall fail or refuse to purchase Designated Securities that it has or they have
agreed to purchase hereunder on such date, and the aggregate amount of
Designated Securities which such defaulting Underwriter or Underwriters agreed
but failed or refused to purchase is not more than one-tenth of the aggregate
amount of the Designated Securities to be purchased on such date, the other
Underwriters shall be obligated severally in the proportions that the amount of
Designated Securities set forth opposite their respective names in the Pricing
Agreement bears to the aggregate amount of Designated Securities set forth
opposite the names of all such non-defaulting Underwriters, or in such other
proportions as the Representatives may specify, to purchase the Designated
Securities which such defaulting Underwriter or Underwriters agreed but failed
or refused to purchase on such date; provided that in no event shall the amount
of Designated Securities that any Underwriter has agreed to purchase pursuant to
this Agreement be increased pursuant to this Section 9 by an amount in excess of
one-ninth of such amount of Designated Securities without the written consent of
such Underwriter. If, at the Time of Delivery, any Underwriter or Underwriters
shall fail or refuse to purchase Designated Securities and the aggregate amount
of Designated Securities with respect to which such default occurs is more than
one-tenth of the aggregate amount of Designated Securities to be purchased on
such date, and arrangements satisfactory to the Representatives and the Company
for the purchase of such Designated Securities are not made within 36 hours
after such default, this Agreement shall terminate without liability on the part
of any non-defaulting Underwriter or the Company. In any such case either the
Representatives or the Company shall have the right to postpone the Closing
Date, but in no event for longer than seven days, in order that the required
changes, if any, in the Registration Statement and in the Prospectus or in any
other documents or arrangements may be effected. Any action taken under this
paragraph shall not relieve any defaulting Underwriter from liability in respect
of any default of such Underwriter under this Agreement.

         If this Agreement shall be terminated by the Underwriters, or any of
them, because of any failure or refusal on the part of the Company to comply
with the terms or to fulfill any of the conditions of this Agreement, or if for
any reason the Company shall be unable to perform its obligations under this
Agreement, the Company will reimburse the Underwriters or such Underwriters as
have so terminated this Agreement with respect to themselves, severally, for all
out-of-pocket expenses (including the fees and disbursements of their counsel)
reasonably incurred by such Underwriters in connection with this Agreement or
the offering contemplated hereunder.

         10. The respective indemnities, agreements, representations, warranties
and other statements of the Designated Trust or the Company and the several
Underwriters, as set forth in this Agreement or made by or on behalf of them,
respectively, pursuant to this Agreement, shall remain in full force and effect,
regardless of any investigation (or any statement as to the results thereof)
made by or on behalf of any Underwriter or any controlling person of any
Underwriter, or the Designated Trust or the Company, or any officer or director
or controlling person of the Designated Trust or the Company, and shall survive
delivery of and payment for the Securities.

         11. If any Pricing Agreement or Over-allotment Option shall be
terminated pursuant to Section 9 hereof, neither the Designated Trust nor the
Company shall then be under any liability to any Underwriter with respect to the
Firm Designated Securities or Optional Designated Securities with respect to
which such Pricing Agreement shall have been terminated except as provided in
Sections 6 and 8 hereof; but, if for any other reason, Designated Securities are
not delivered by or on behalf of the Designated Trust or the Company as provided
herein, the Company will reimburse the Underwriters through the Representatives
for all out-of-pocket expenses approved in writing by the Representatives,
including fees and disbursements of counsel, reasonably incurred by the
Underwriters in making preparations for the purchase, sale and delivery of such
Designated Securities, but the Designated Trust or the Company shall then be
under no further liability to any Underwriter with respect to such Designated
Securities except as provided in Sections 6 and 8 hereof.

         12. In all dealings hereunder, the Representatives of the Underwriters
of Designated Securities shall act on behalf of each of such Underwriters, and
the parties hereto shall be entitled to act and rely upon any statement,
request, notice or agreement on behalf of any Underwriter made or given by such
Representatives jointly or by such of the Representatives, if any, as may be
designated for such purpose in the Pricing Agreement.

         All statements, requests, notices and agreements hereunder shall be in
writing, and if to the Underwriters shall be delivered or sent by mail, telex or
facsimile transmission to the address of the Representatives as set forth in the
Pricing Agreement; and if to the Designated Trust or the Company shall be
delivered or sent by mail, telex or facsimile transmission to the address of the
Designated Trust or the Company, respectively, set forth in the Registration
Statement, Attention: Teresa A. Fehrman, Treasurer, and Harry A. Johnson, III,
Executive Vice President and General Counsel; provided, however, that any notice
to an Underwriter pursuant to Section 8(c) hereof shall be delivered or sent by
mail, telex or facsimile transmission to such Underwriter at its address set
forth in its Underwriters' Questionnaire, or telex constituting such
Questionnaire, which address will be supplied to the Designated Trust and the
Company by the Representatives upon request. Any such statements, requests,
notices or agreements shall take effect upon receipt thereof.

         13. Each Pricing Agreement shall be binding upon, and inure solely to
the benefit of, the Underwriters, each Designated Trust, the Company and, to the
extent provided in Sections 8 and 10 hereof, the officers and directors of each
Designated Trust, the Company and each person who controls any Designated Trust
or the Company or any Underwriter, and their respective heirs, executors,
administrators, successors and assigns, and no other person shall acquire or
have any right under or by virtue of any such Pricing Agreement. No purchaser of
any of the Securities from any Underwriter shall be deemed a successor or assign
by reason merely of such purchase.

         14. As used herein, the term "business day" shall mean any day when the
Commission's office in Washington, D.C. is open for business.

         15. EACH PRICING AGREEMENT SHALL BE GOVERNED BY AND CONSTRUED IN
ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK.

         16. Each Pricing Agreement may be executed by any one or more of the
parties hereto and thereto in any number of counterparts, each of which shall be
deemed to be an original, but all such respective counterparts shall together
constitute one and the same instrument.

         Pursuant to Section 7(d) of the Standard Provisions, the accountants
shall furnish letters to the Underwriters to the effect that:

                  (i) They are independent certified public accountants with
         respect to the Designated Trust and the Company and its subsidiaries
         within the meaning of the Act and the applicable published rules and
         regulations thereunder;

                  (ii) In their opinion, the financial statements and any
         supplementary financial information and schedules (and, if applicable,
         financial forecasts and/or pro forma financial information) examined by
         them and included or incorporated by reference in the Registration
         Statement or the Prospectus comply as to form in all material respects
         with the applicable accounting requirements of the Act or the Exchange
         Act, as applicable, and the related published rules and regulations
         thereunder; and, if applicable, they have made a review in accordance
         with standards established by the American Institute of Certified
         Public Accountants of the consolidated interim financial statements,
         selected financial data, pro forma financial information, financial
         forecasts and/or condensed financial statements derived from audited
         financial statements of the Company for the periods specified in such
         letter, as indicated in their reports thereon, copies of which have
         been separately furnished to the representatives of the Underwriters
         (the "Representatives");

                  (iii) They have made a review in accordance with standards
         established by the American Institute of Certified Public Accountants
         of the unaudited condensed consolidated statements of income,
         consolidated balance sheets and consolidated statements of cash flows
         included in the Prospectus and/or included in the Company's quarterly
         reports on Form 10-Q incorporated by reference into the Prospectus as
         indicated in their reports thereon copies of which have been separately
         furnished to the Representatives; and on the basis of specified
         procedures including inquiries of officials of the Company who have
         responsibility for financial and accounting matters regarding whether
         the unaudited condensed consolidated financial statements referred to
         in paragraph (vi)(A)(i) below comply as to form in all material
         respects with the applicable accounting requirements of the Act and the
         Exchange Act and the related published rules and regulations, nothing
         came to their attention that caused them to believe that the unaudited
         condensed consolidated financial statements do not comply as to form in
         all material respects with the applicable accounting requirements of
         the Act and the Exchange Act and the related published rules and
         regulations;

                  (iv) The unaudited selected financial information with respect
         to the consolidated results of operations and financial position of the
         Company for the five most recent fiscal years included in the
         Prospectus and included or incorporated by reference in Item 6 of the
         Company's Annual Report on Form 10-K for the most recent fiscal year
         agrees with the corresponding amounts (after restatement where
         applicable) in the audited consolidated financial statements for such
         five fiscal years which were included or incorporated by reference in
         the Company's Annual Reports on Form 10-K for such fiscal years;

                  (v) They have compared the information in the Prospectus under
         selected captions with the disclosure requirements of Regulation S-K
         and on the basis of limited procedures specified in such letter nothing
         came to their attention as a result of the foregoing procedures that
         caused them to believe that this information does not conform in all
         material respects with the disclosure requirements of items 301, 302,
         402 and 503(d), respectively, of Regulation S-K;

                  (vi) On the basis of limited procedures, not constituting an
         examination in accordance with generally accepted auditing standards,
         consisting of a reading of the unaudited financial

                                                                               2



         statements and other information referred to below, a reading of the
         latest available interim financial statements of the Company and its
         subsidiaries, inspection of the minute books of the Company and its
         subsidiaries since the date of the latest audited financial statements
         included or incorporated by reference in the Prospectus, inquiries of
         officials of the Company and its subsidiaries responsible for financial
         and accounting matters and such other inquiries and procedures as may
         be specified in such letter, nothing came to their attention that
         caused them to believe that:

                  (A) (i) the unaudited condensed consolidated statements of
         income, consolidated balance sheets and consolidated statements of cash
         flows included in the Prospectus and/or included or incorporated by
         reference in the Company's Quarterly Reports on Form 10-Q incorporated
         by reference in the Prospectus do not comply as to form in all material
         respects with the applicable accounting requirements of the Exchange
         Act and the related published rules and regulations, or (ii) any
         material modifications should be made to the unaudited condensed
         consolidated statements of income, consolidated balance sheets and
         consolidated statements of cash flows included in the Prospectus or
         included in the Company's Quarterly Reports on Form 10-Q incorporated
         by reference in the Prospectus, for them to be in conformity with
         generally accepted accounting principles;

                  (B) any other unaudited income statement data and balance
         sheet items included in the Prospectus do not agree with the
         corresponding items in the unaudited consolidated financial statements
         from which such data and items were derived, and any such unaudited
         data and items were not determined on a basis substantially consistent
         with the basis for the corresponding amounts in the audited
         consolidated financial statements included or incorporated by reference
         in the Company's Annual Report on Form 10-K for the most recent fiscal
         year;

                  (C) the unaudited financial statements which were not included
         in the Prospectus but from which were derived the unaudited condensed
         financial statements referred to in clause (A) and any unaudited income
         statement data and balance sheet items included in the Prospectus and
         referred to in Clause (B) were not determined on a basis substantially
         consistent with the basis for the audited financial statements included
         or incorporated by reference in the Company's Annual Report on Form
         10-K for the most recent fiscal year;

                  (D) any unaudited pro forma consolidated condensed financial
         statements included or incorporated by reference in the Prospectus do
         not comply as to form in all material respects with the applicable
         accounting requirements of the Act and the published rules and
         regulations thereunder or the pro forma adjustments have not been
         properly applied to the historical amounts in the compilation of those
         statements;

                  (E) as of a specified date not more than five days prior to
         the date of such letter, there have been any changes in the
         consolidated capital stock (other than relating to issuances pursuant
         to stock benefit plans and dividend reinvestment plans and acquisitions
         of capital stock pursuant to announced share repurchase programs) or
         any increase in the consolidated long-term debt of the Company and its
         subsidiaries, or any decreases in consolidated net current assets or
         stockholders' equity or other items specified by the Representatives,
         or any increases in any items specified by the Representatives, in each
         case as compared with amounts shown in the latest balance sheet
         included or incorporated by reference in the Prospectus, except in each
         case for changes, increases or decreases which the Prospectus discloses
         have occurred or may occur or which are described in such letter; and

                  (F) for the period from the date of the latest financial
         statements included or incorporated by reference in the Prospectus to
         the specified date referred to in Clause (E) there were any decreases
         in consolidated net revenues or operating profit or the total or per
<PAGE>   30
                                                                               3


         share amounts of consolidated net income or other items specified by
         the Representatives, or any increases in any items specified by the
         Representatives, in each case as compared with the comparable period of
         the preceding year and with any other period of corresponding length
         specified by the Representatives, except in each case for increases or
         decreases which the Prospectus discloses have occurred or may occur or
         which are described in such letter; and

                  (vii) In addition to the examination referred to in their
         report(s) included or incorporated by reference in the Prospectus and
         the limited procedures, inspection of minute books, inquiries and other
         procedures referred to in paragraphs (iii) and (vi) above, they have
         carried out certain specified procedures, not constituting an
         examination in accordance with generally accepted auditing standards,
         with respect to certain amounts, percentages and financial information
         specified by the Representatives which are derived from the general
         accounting records of the Company and its subsidiaries, which appear in
         the Prospectus (excluding documents incorporated by reference), or in
         Part II of, or in exhibits and schedules to, the Registration Statement
         specified by the Representatives or in documents incorporated by
         reference in the Prospectus specified by the Representatives, and have
         compared certain of such amounts, percentages and financial information
         with the accounting records of the Company and its subsidiaries and
         have found them to be in agreement.

         All references in this Annex II to the Prospectus shall be deemed to
refer to the Prospectus (including the documents incorporated by reference
therein) as defined in the Standard Provisions as of the date of the letter
delivered on the date of the Pricing Agreement for purposes of such letter and
to the Prospectus as amended or supplemented (including the documents
incorporated by reference therein) in relation to the applicable Designated
Securities for purposes of the letter delivered at the Time of Delivery for such
Designated Securities.

installment of principal thereof means the date specified pursuant to the terms
of such Security as the date on which the principal of such Security is due and
payable, as such date may be shortened or extended as provided pursuant to the
terms of such Security and this Indenture. When used with respect to any
installment of interest on any Security, "Stated Maturity" means the date
specified pursuant to the terms of such Security as the date on which such
installment of the interest is due and payable.

         "Subsidiary" means a corporation more than 50% of the outstanding
voting stock of which is owned, directly or indirectly, by the Company or by one
or more other Subsidiaries, or by the Company and one or more other
Subsidiaries. For purposes of this definition, "voting stock" means stock which
ordinarily has voting power for the election of directors, whether at all times
or only so long as no senior class of stock has such voting power by reason of
any contingency.

         "Tax Event", with respect to Securities held by a Trust, means the
receipt by such Trust of an Opinion of Counsel (as defined in the relevant Trust
Agreement) experienced in such matters to the effect that, as a result of any
amendment to, or change (including any announced proposed change) in, the laws
(or any regulations thereunder) of the United States or any political
subdivision or taxing authority thereof or therein, or as a result of any
official administrative pronouncement or judicial decision interpreting or
applying such laws or regulations, which amendment or change is effective or
which proposed change, pronouncement or decision is announced on or after the
date of issuance of the Preferred Securities of such Trust, there is more than
an insubstantial risk that (i) such Trust is, or will be within 90 days of the
date of such Opinion of Counsel, subject to United States federal income tax
with respect to income received or accrued on the corresponding series of
Securities issued by the Company to such Trust, (ii) interest payable by the
Company on such corresponding series of Securities is not, or within 90 days of
the date of such Opinion of Counsel, will not be, deductible by the Company, in
whole or in part, for United States federal income tax purposes or (iii) such
Trust is, or will be within 90 days of the date of such Opinion of Counsel,
subject to more than a de minimis amount of other taxes, duties or other
governmental charges. With respect to securities not held by a Trust, "Tax
Event" means the receipt by the Company of an opinion of counsel experienced
in such matters to the effect that, as a result of any amendment to, or change
(including any announced proposed change) in, the laws (or any regulations
thereunder) of the United States or any political subdivision or taxing
authority thereof or therein, or as a result of any official administrative
pronouncement or judicial decision interpreting or applying such laws or
regulations, which amendment or change is effective or which proposed change,
pronouncement or decision is announced on or after the date of issuance of the
applicable series of Securities under this Indenture, there is more than an
insubstantial risk that interest payable by the Company on such series of
Securities is not, or within 90 days of the date of such opinion will not be,
deductible by the Company, in whole or in part, for United States federal
income tax purposes.

         "Trust" has the meaning specified in the first recital of this
Indenture.

         "Trust Agreement", with respect to a Trust, means a Trust Agreement
substantially in the form attached hereto as Annex A, as amended by the form of
Amended and Restated Trust Agreement substantially in the form attached hereto
as Annex B, or substantially in such form as may be specified as contemplated by
Section 3.1 with respect to the Securities of any series, in each case as
amended from time to time.

         "Trustee" means the Person named as the "Trustee" in the first
paragraph of this instrument until a successor Trustee shall have become such
pursuant to the applicable provisions of this Indenture, and thereafter
"Trustee" shall mean or include each Person who is then a Trustee hereunder and,
if at any time there is more than one such Person, "Trustee" as used

                                                                              10

this Indenture.

         "Vice President", when used with respect to the Company means any duly
appointed vice president, whether or not designated by a number or a word or
words added before or after the title "vice president."

         SECTION 1.2.   Compliance Certificate and Opinions.

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

         Every certificate or opinion with respect to compliance with a
condition or covenant provided for in this Indenture (other than the
certificates provided pursuant to Section 10.4) shall include:

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

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

         (3) a statement that, in the opinion of each such individual, he has
made or caused to be made such examination or investigation as is necessary to

         SECTION 1.3.   Forms of Documents Delivered to Trustee.

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

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

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

         SECTION 1.4.   Acts of Holders.

         (a) Any request, demand, authorization, direction, notice, consent,
waiver or other action provided by this Indenture to be given to or taken by
Holders may be embodied in and evidenced by one or more instruments of
substantially similar tenor signed by such Holders in person or by an agent or
proxy duly appointed in writing; and, except as herein otherwise expressly
provided, such action shall become effective when such instrument or instruments
is or are delivered to the Trustee, and, where it is hereby expressly required,
to the Company. Such instrument or instruments (and the action embodied therein
and evidenced thereby) are herein sometimes referred to as the "Act" of the
Holders signing such instrument or instruments. Proof of execution of any such
instrument or of a writing appointing any such agent or proxy shall be
sufficient for any purpose of this Indenture and (subject to Section 6.1)
conclusive in favor of the Trustee and the Company, if made in the manner
provided in this Section.

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

         (c) The fact and date of the execution by any Person of any such
instrument or writing, or the authority of the Person executing the same, may
also be proved in any other


<PAGE>   19


                                                                              12



manner which the Trustee deems sufficient and in accordance with such reasonable
rules as the Trustee may determine.

         (d) The ownership of Securities shall be proved by the Securities
Register.

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

         (f) The Company may set any day as a record date for the purpose of
determining the Holders of Outstanding Securities entitled to give, make or take
any request, demand, authorization, direction, notice, consent, waiver or other
action provided or permitted by this Indenture to be given, made or taken by
Holders of Securities of such series, provided that the Company may not set a
record date for, and the provisions of this paragraph shall not apply with
respect to, the giving or making of any notice, declaration, request or
direction referred to in the next paragraph. If any record date is set pursuant
to this paragraph, the Holders of the relevant Outstanding Securities on such
record date, and no other Holders, shall be entitled to take the relevant
action, whether or not such Holders remain Holders after such record date,
provided that no such action shall be effective hereunder unless taken on or
prior to the applicable Expiration Date by Holders of the requisite principal
amount of the relevant Outstanding Securities on such record date. Nothing in
this paragraph shall be construed to prevent the Company from setting a new
record date for any action for which a record date has previously been set
pursuant to this paragraph (whereupon the record date previously set shall
automatically and with no action by any Person be cancelled and of no effect),
and nothing in this paragraph shall be construed to render ineffective any
action taken by Holders of the requisite principal amount of the relevant
Outstanding Securities on the date such action is taken. Promptly after any
record date is set pursuant to this paragraph, the Company, at its own expense,
shall cause notice of such record date, the proposed action by Holders and the
applicable Expiration Date to be given to the Trustee in writing and to each
Holder of the relevant Securities in the manner set forth in Section 1.6.

         The Trustee may set any day as a record date for the purpose of
determining the Holders of Outstanding Securities entitled to join in the giving
or making of (i) any Notice of Default, (ii) any declaration of acceleration
referred to in Section 5.2, (iii) any request to institute proceedings referred
to in Section 5.7(2) or (iv) any direction referred to in Section 5.12, in each
case with respect to the relevant Securities. If any record date is set pursuant
to this paragraph, the Holders of the relevant Outstanding Securities on such
record date, and no other Holders, shall be entitled to join in such notice,
declaration, request or direction, whether or not such Holders remain Holders
after such record date, provided that no such action shall be effective
hereunder unless taken on or prior to the applicable Expiration Date by Holders
of the requisite principal amount of the relevant Outstanding Securities on such
record date. Nothing in this paragraph shall be construed to prevent the Trustee
from setting a new record date for any action for which a record date has
previously been set pursuant to this paragraph (whereupon the record date
previously set shall automatically and with no action by any Person


<PAGE>   20


                                                                              13



be cancelled and of no effect), and nothing in this paragraph shall be construed
to render ineffective any action taken by Holders of the requisite principal
amount of the relevant Outstanding Securities on the date such action is taken.
Promptly after any record date is set pursuant to this paragraph, the Trustee,
at the Company's expense, shall cause notice of such record date, the proposed
action by Holders and the applicable Expiration Date to be given to the Company
in writing and to each Holder of the relevant Securities in the manner set forth
in Section 1.6.

         With respect to any record date set pursuant to this Section, the party
hereto which sets such record date may designate any day as the "Expiration
Date" and from time to time may change the Expiration Date to any earlier or
later day, provided that no such change shall be effective unless notice of the
proposed new Expiration Date is given to the other party hereto in writing, and
to each Holder of the relevant Outstanding Securities in the manner set forth in
Section 1.6, on or prior to the existing Expiration Date. If an Expiration Date
is not designated with respect to any record date set pursuant to this Section,
the party hereto which set such record date shall be deemed to have initially
designated the 180th day after such record date as the Expiration Date with
respect thereto, subject to its right to change the Expiration Date as provided
in this paragraph. Notwithstanding the foregoing, no Expiration Date shall be
later than the 180th day after the applicable record date.

         (g) Without limiting the foregoing, a Holder entitled hereunder to take
any action hereunder with regard to any particular Security may do so with
regard to all or any part of the principal amount of such Security or by one or
more duly appointed agents each of which may do so pursuant to such appointment
with regard to all or any part of such principal amount.

         SECTION 1.5.   Notices, Etc. to Trustee and Company.

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

         (1) the Trustee by any Holder, any holder of Preferred Securities or
the Company shall be sufficient for every purpose hereunder if made, given,
furnished or filed in writing to or with the Trustee at its Corporate Trust
Office, or

         (2) the Company by the Trustee, any Holder or any holder of Preferred
Securities shall be sufficient for every purpose (except as otherwise provided
in Section 5.1) hereunder if in writing and mailed, first class, postage
prepaid, to the Company addressed to it at the address of its principal office
specified in the first paragraph of this instrument or at any other address
previously furnished in writing to the Trustee by the Company.

         SECTION 1.6.   Notice to Holders; Waiver.

         Where this Indenture provides for notice to Holders of any event, such
notice shall be sufficiently given (unless otherwise herein expressly provided)
if in writing and mailed, first class postage prepaid, to each Holder affected
by such event, at the address of such Holder as it appears in the Securities
Register, not later than the latest date, and not earlier than the earliest
date, prescribed for the giving of such notice. In any case where notice to
Holders is given by mail, neither the failure to mail such notice, nor any
defect in any notice so mailed, to any particular Holder shall affect the
sufficiency of such notice with respect to other Holders. Where this Indenture
provides for notice in any manner, such notice may be waived in writing by the
Person entitled to receive such notice, either before or after the event, and
such waiver shall be the equivalent of such notice. Waivers of notice by Holders
shall be filed with the Trustee, but such filing shall not be a condition
precedent to the validity of any action taken in reliance upon such waiver.

         SECTION 1.7.   Conflict with Trust Indenture Act.

         If any provision of this Indenture limits, qualifies or conflicts with
the duties imposed by any of Sections 310 to 317, inclusive, of the Trust
Indenture Act through operation of Section 318(c) thereof, such imposed duties
shall control.

         SECTION 1.8.   Effect of Headings and Table of Contents.

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

         SECTION 1.9.   Successors and Assigns.

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

         SECTION 1.10.  Separability Clause.

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

         SECTION 1.11   Benefits of Indenture.

         Nothing in this Indenture or in the Securities, express or implied,
shall give to any Person, other than the parties hereto and their successors and
assigns, the holders of Senior Indebtedness, the Holders of the Securities and,
to the extent expressly provided in Sections 5.2, 5.8, 5.9, 5.11, 5.13, 9.1 and
9.2, the holders of Preferred Securities, any benefit or any legal or equitable
right, remedy or claim under this Indenture.

         THIS INDENTURE AND THE SECURITIES SHALL BE GOVERNED BY AND CONSTRUED IN
ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK, WITHOUT REGARD TO CONFLICTS
OF LAW PRINCIPLES THEREOF.

         SECTION 1.13.   Non-Business Days.

         In any case where any Interest Payment Date, Redemption Date or Stated
Maturity of any Security shall not be a Business Day, then (notwithstanding any
other provision of this Indenture or the Securities) payment of interest or
principal (and premium, if any) need not be made on such date, but may be made
on the next succeeding Business Day (and no interest shall accrue for the period
from and after such Interest Payment Date, Redemption Date or Stated Maturity,
as the case may be, until such next succeeding Business Day) except that, if
such Business Day is in the next succeeding calendar year, such payment shall be
made on the immediately preceding Business Day (in each case with the same force
and effect as if made on the Interest Payment Date or Redemption Date or at the
Stated Maturity).

             __% JUNIOR SUBORDINATED DEFERRABLE INTEREST DEBENTURES

No.              $

         FIRST TENNESSEE NATIONAL CORPORATION, a corporation organized and
existing under the laws of the state of Tennessee (hereinafter called the
"Company", which term includes any successor corporation under the Indenture
hereinafter referred to), for value received, hereby promises to pay to     
   , or registered assigns, the principal sum of
              Dollars on __________ __, ____[; provided that the Company may,
subject to certain conditions set forth in Section 3.14 of the Indenture, (i)
shorten the Stated Maturity of the principal of this Security to a date not
earlier than __________, and (ii) extend the Stated Maturity of the principal of
this Security at any time on one or more occasions, but in no event to a date
later than __________]. The Company further promises to pay interest on said
principal sum from , or from the most recent interest payment date (each such
date, an "Interest Payment Date") on which interest has been paid or duly
provided for, [monthly] [quarterly] [semi-annually] [if applicable, insert -
(subject to deferral as set forth herein)] in arrears on [insert applicable
Interest Payment Dates] of each year, commencing   ,   , at the rate of
% per annum, until the principal hereof shall have become due and payable, [if 
applicable, insert plus Additional Interest, if any,] until the principal
hereof is paid or duly provided for or made available for payment
[if applicable, insert - and on any overdue principal and (without
duplication and to the extent that payment of such interest is enforceable under
applicable law) on any overdue installment of interest at the rate of % per
annum, compounded [monthly] [quarterly] [semi-annually]]. The amount of interest
payable for any period shall be computed on the basis of twelve 30-day months
and a 360-day year. The amount of interest payable for any partial period shall
be computed on the basis of the number of days elapsed in a 360-day year of
twelve 30-day months. In the event that any date on which interest is payable on
this Security is not a Business Day, then a payment of the interest payable on
such date will be made on the next succeeding day which is a Business Day (and
without any interest or other payment in respect of any such delay), except
that, if such Business Day is in the next succeeding calendar year, such payment
shall be made on the immediately preceding Business Day, in each case with the
same force and effect as if made on the date the payment was originally payable.
A "Business Day" shall mean any day other than (i) a Saturday or Sunday, (ii) a
day on which banking institutions in The City of New York are authorized or
required by law or executive order to remain closed or (iii) a day on which the
Corporate Trust Office of the Trustee [if applicable, insert - or the principal
office of the Property Trustee under the Trust Agreement hereinafter referred to
for First Tennessee Capital _,] is closed for business. The interest installment
so payable, and punctually paid or duly provided for, on any Interest Payment
Date will, as provided in the Indenture, be paid to the Person in whose name
this Security (or one or more Predecessor Securities) is registered at the close
of business on the Regular Record Date for such interest installment, which
shall be the [insert definition of Regular Record Dates]. Any such interest
installment not so punctually paid or duly provided

                                                                              17



for shall forthwith cease to be payable to the Holder on such Regular Record
Date and may either be paid to the Person in whose name this Security (or one or
more Predecessor Securities) is registered at the close of business on a Special
Record Date for the payment of such Defaulted Interest to be fixed by the
Trustee, notice whereof shall be given to Holders of Securities of this series
not less than 10 days prior to such Special Record Date, or be paid at any time
in any other lawful manner not inconsistent with the requirements of any
securities exchange or automated quotation system on which the Securities of
this series may be listed or traded, and upon such notice as may be required by
such exchange or self-regulatory organization, all as more fully provided in
said Indenture.

         [If applicable, insert - So long as no Event of Default has occurred
and is continuing, the Company shall have the right at any time during the term
of this Security to defer payment of interest on this Security, at any time or
from time to time, for up to    consecutive [monthly] [quarterly] [semi-annual]
interest payment periods with respect to each deferral period (each an
"Extension Period"), during which Extension Periods the Company shall have the
right to make partial payments of interest on any Interest Payment Date, and at
the end of which the Company shall pay all interest then accrued and unpaid
(together with Additional Interest thereon to the extent permitted by applicable
law); provided, however, that no Extension Period shall extend beyond the Stated
Maturity of the principal of this Security; provided, further, that during any
such Extension Period, the Company shall not, and shall not permit any
Subsidiary of the Company to, (i) declare or pay any dividends or distributions
on or redeem, purchase, acquire or make a liquidation payment with respect to,
any of the Company's capital stock or (ii) make any payment of principal of or
interest or premium, if any, on or repay, repurchase or redeem any debt security
of the Company that ranks pari passu with or junior in interest to this Security
or (iii) make any guarantee payments with respect to any guarantee by the
Company of the debt securities of any Subsidiary of the Company if such
guarantee ranks pari passu with or junior in interest to this Security (other
than (a) dividends or distributions in the Company's capital stock, (b) any
declaration of a dividend in connection with the implementation of a Rights Plan
or the redemption or repurchase of any rights distributed pursuant to a Rights
Plan, (c) payments under the Guarantee with respect to this Security, and (d)
purchases of Common Stock related to the issuance of Common Stock or rights or
options under any of the Company's benefit plans for its directors, officers,
employees or other persons within the definition of "employee" for purposes of a
registration of shares for an employee benefit plan of the Company, related
to the issuance of Common Stock or rights under a dividend reinvestment and
stock purchase plan, or related to the issuance of Common Stock (or securities
convertible or exchangeable for Common Stock) as consideration in an acquisition
transaction that was entered into prior to the commencement of such Extension

provisions, (b) authorizes and directs the Trustee on his behalf to take such
actions as may be necessary or appropriate to effectuate the subordination so
provided and (c) appoints the Trustee his attorney-in-fact for any and all such
purposes. Each Holder hereof, by his acceptance hereof, waives all notice of the
acceptance of the subordination provisions contained herein and in the Indenture
by each holder of Senior Indebtedness, whether now outstanding or hereafter
incurred, and waives reliance by each such holder upon said provisions.

shall not be entitled to any benefit under the Indenture or be valid or
obligatory for any purpose.

         IN WITNESS WHEREOF, the Company has caused this instrument to be duly
executed under its corporate seal.

series issued to a Trust, if upon an Event of Default, the Trustee or the
Holders of not less than 25% in principal amount of the Outstanding Securities
of this series fails to declare the principal of all the Securities of this
series to be immediately due and payable, the holders of at least 25% in
aggregate Liquidation Amount of the Preferred Securities then outstanding shall
have such right by a notice in writing to the Company and the Trustee; and upon
any such declaration the principal amount of and the accrued interest (including
any Additional Interest) on all the Securities of this series shall become

payable immediately, by a notice in writing to the Company (and to the Trustee
if given by Holders), provided that, in the case of the Securities of this
series issued to a Trust, if upon an Event of Default, the Trustee or the
Holders of the requisite principal amount of the Outstanding Securities of this
series fails to declare the principal of all the Securities of this series to be
immediately due and payable, the holders of at least 25% in aggregate
Liquidation Amount of the Preferred Securities then outstanding shall have such
right by a notice in writing to the Company and the Trustee. Such amount shall
be equal to - insert formula for determining the

amount. Upon any such declaration, such amount of the principal of and the
accrued interest (including any Additional Interest) on all the Securities of
this series shall become immediately due and payable, provided that the payment
of principal and interest (including any Additional Interest) on such Securities
shall remain subordinated to the extent provided in Article XIII of the
Indenture. Upon payment (i) of the amount of principal so declared due and
payable and (ii) of interest on any overdue principal and overdue interest (in
each case to the extent that the payment of such interest shall be legally

more new Securities of this series, of authorized denominations and for the same
aggregate principal amount, will be issued to the designated transferee or
transferees. No service charge shall be made for any such registration of
transfer or exchange, but the Company may require payment of a sum sufficient to
cover any tax or other governmental charge payable in connection therewith.

         Prior to due presentment of this Security for registration of transfer,

provided in the Indenture and subject to certain limitations therein set forth,
Securities of this series are exchangeable for a like aggregate principal amount

interest therein, the Holder of, and any Person that acquires a beneficial
interest in, this Security agree that for United States federal, state and local

together with a Company Order for the authentication and delivery of such

authenticate and make such Securities available for delivery. If the form or
terms of the Securities of the series have been established by or pursuant to
one or more Board Resolutions as permitted by Sections 2.1 and 3.1, in

under this Indenture in relation to such Securities, the Trustee shall be
entitled to receive, and (subject to Section 6.1) shall be fully protected in
relying upon, an Opinion of Counsel stating,

                  (1) if the form of such Securities has been established by or
         pursuant to Board Resolution as permitted by Section 2.1, that such
         form has been established in conformity with the provisions of this
         Indenture;

                  (2) if the terms of such Securities have been established by
         or pursuant to Board Resolution as permitted by Section 3.1, that such
         terms have been established in conformity with the provisions of this
         Indenture;

                  (3) that such Securities, when authenticated and delivered by
         the Trustee and issued by the Company in the manner and subject to any
         conditions specified in such Opinion of Counsel, will constitute valid
         and legally binding obligations of the Company enforceable in
         accordance with their terms, subject to bankruptcy, insolvency,
         fraudulent transfer, reorganization, moratorium and similar laws of
         general applicability relating to or affecting creditors' rights and to
         general equity principles; and

                  (4) that all requirements of New York and Federal law and the

         conditions set forth in this Indenture which are conditions precedent
         hereto, have been complied with.

If such form or terms have been so established, the Trustee shall not be
required to authenticate such Securities if the issue of such Securities
pursuant to this Indenture will affect the Trustee's own rights, duties or
immunities under the Securities and this Indenture or otherwise in a manner
which is not reasonably acceptable to the Trustee.

                  Notwithstanding the provisions of Section 3.1 and of the
preceding paragraph, if all Securities of a series are not to be originally
issued at one time, it shall not be necessary to deliver the Officers'
Certificate otherwise required pursuant to Section 3.1 or the Company Order and
Opinion of Counsel otherwise required pursuant to such preceding paragraph at or
prior to the authentication of each Security of such series if such documents
are delivered at or prior to the authentication upon original issuance of the
first Security of such series to be issued.

         Each Security shall be dated the date of its authentication.

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

                                                                              27



Notwithstanding the foregoing, if any Security shall have been authenticated and
delivered hereunder but never issued and sold by the Company, and the Company
shall deliver such Security to the Trustee for cancellation as provided in
Section 3.9, for all purposes of this Indenture such Security shall be deemed
never to have been authenticated and delivered hereunder and shall not be
entitled to the benefits of this Indenture.

         SECTION 3.4.   Temporary Securities.

         Pending the preparation of definitive Securities of any series, the
Company may execute, and upon Company Order the Trustee shall authenticate and
make available for delivery, temporary Securities which are printed,
lithographed, typewritten, mimeographed or otherwise produced, in any authorized
denomination, substantially of the tenor of the definitive Securities of such
series in lieu of which they are issued and with such appropriate insertions,
omissions, substitutions and other variations as the officers executing such
Securities may determine, as evidenced by their execution of such Securities.

        If temporary Securities of any series are issued, the Company will cause
definitive Securities of such series to be prepared without unreasonable delay.
After the preparation of definitive Securities, the temporary Securities shall
be exchangeable for definitive Securities upon surrender of the temporary
Securities at the office or agency of the Company designated for that purpose
without charge to the Holder. Upon surrender for cancellation of any one or more
temporary Securities, the Company shall execute and the Trustee shall
authenticate and make available for delivery in exchange therefor one or more
definitive Securities of the same series, of any authorized denominations, of
like aggregate principal amount, having the same Original Issue Date and Stated
Maturity and having the same terms as such temporary Securities. Until so
exchanged, the temporary Securities of any series shall in all respects be
entitled to the same benefits under this Indenture as definitive Securities of
such series.

         SECTION 3.5.   Registration, Transfer and Exchange.

         The Company shall cause to be kept at the Corporate Trust Office of the
Trustee a register in which, subject to such reasonable regulations as it may
prescribe, the Company shall provide for the registration of Securities and of
transfers of Securities. Such register is herein sometimes referred to as the
"Securities Register." The Trustee is hereby appointed "Securities Registrar"
for the purpose of registering Securities and transfers of Securities as herein
provided.


         Upon surrender for registration of transfer of any Security at the
office or agency of the Company designated for that purpose the Company shall
execute, and the Trustee shall authenticate and make available for delivery, in
the name of the designated transferee or transferees, one or more new Securities
of the same series of any authorized denominations, of a like aggregate
principal amount, of the same Original Issue Date and Stated Maturity and having
the same terms.

         At the option of the Holder, Securities may be exchanged for other
Securities of the same series of any authorized denominations, of a like
aggregate principal amount, of the same Original Issue Date and Stated Maturity
and having the same terms, upon surrender of the


<PAGE>   35


                                                                              28



Securities to be exchanged at such office or agency. Whenever any Securities are
so surrendered for exchange, the Company shall execute, and the Trustee shall
authenticate and make available for delivery, the Securities which the Holder
making the exchange is entitled to receive.

         All Securities issued upon any transfer or exchange of Securities shall
be the valid obligations of the Company, evidencing the same debt, and entitled
to the same benefits under this Indenture, as the Securities surrendered upon
such transfer or exchange.

         Every Security presented or surrendered for transfer or exchange shall
(if so required by the Company or the Securities Registrar) be duly endorsed, or
be accompanied by a written instrument of transfer in form satisfactory to the
Company and the Securities Registrar, duly executed by the Holder thereof or his
attorney duly authorized in writing.

         No service charge shall be made to a Holder for any transfer or
exchange of Securities, but the Company may require payment of a sum sufficient
to cover any tax or other governmental charge that may be imposed in connection
with any transfer or exchange of Securities.

                  The provisions of Clauses (1), (2), (3) and (4) below shall 
apply only to Global Securities:

                  (1) Each Global Security authenticated under this Indenture
         shall be registered in the name of the Depositary designated for such
         Global Security or a nominee thereof and delivered to such Depositary
         or a nominee thereof or custodian therefor, and each such Global
         Security shall constitute a single Security for all purposes of this
         Indenture.

                  (2) Notwithstanding any other provision in this Indenture, no
         Global Security may be exchanged in whole or in part for Securities
         registered, and no transfer of a Global Security in whole or in part
         may be registered, in the name of any Person other than the Depositary
         for such Global Security or a nominee thereof unless (A) such
         Depositary (i) has notified the Company that it is unwilling or unable
         to continue as Depositary for such Global Security or (ii) has ceased
         to be a clearing agency registered under the Exchange Act at a time
         when the Depositary is required to be so registered to act as
         depositary, in either case unless the Company has approved a successor
         Depositary within 90 days, (B) there shall have occurred and be
         continuing an Event of Default with respect to such Global Security,
         (C) the Company in its sole discretion determines that such Global
         Security will be so exchangeable or transferable or (D) there shall
         exist such circumstances, if any, in addition to or in lieu of the
         foregoing as have been specified for this purpose as contemplated by
         Section 3.1.

                  (3) Subject to Clause (2) above, any exchange of a Global
         Security for other Securities may be made in whole or in part, and all
         Securities issued in exchange for a Global Security or any portion
         thereof shall be registered in such names as the Depositary for such
         Global Security shall direct.

                  (4) Every Security authenticated and delivered upon
         registration of transfer of, or in exchange for or in lieu of, a Global
         Security or any portion thereof, whether


<PAGE>   36


                                                                              29



         pursuant to this Section, Section 3.4, 3.6, 9.6 or 11.6 or otherwise,
         shall be authenticated and delivered in the form of, and shall be, a
         Global Security, unless such Security is registered in the name of a
         Person other than the Depositary for such Global Security or a nominee
         thereof.

         Neither the Company nor the Trustee shall be required, pursuant to the
provisions of this Section, (a) to issue, transfer or exchange any Security of
any series during a period beginning at the opening of business 15 days before
the mailing of notice of redemption of Securities pursuant to Article XI and
ending at the close of business on the day of such mailing of notice of
redemption or (b) to transfer or exchange any Security selected for redemption
in whole or in part, except, in the case of any Security to be redeemed in part,
any portion thereof not to be redeemed.

         SECTION 3.6.   Mutilated, Destroyed, Lost and Stolen Securities.

         If any mutilated Security is surrendered to the Trustee together with
such security or indemnity as may be required by the Company or the Trustee to
hold each of them harmless, the Company shall execute and the Trustee shall
authenticate and make available for delivery in exchange therefor a new Security
of the same issue and series of like tenor and principal amount, having the same
Original Issue Date and Stated Maturity and bearing the same interest rate as
such mutilated Security, and bearing a number not contemporaneously outstanding.

         If there shall be delivered to the Company and to the Trustee (i)
evidence to their satisfaction of the destruction, loss or theft of any
Security, and (ii) such security or indemnity as may be required by them to hold
each of them harmless, then, in the absence of notice to the Company or the
Trustee that such Security has been acquired by a bona fide purchaser, the
Company shall execute and upon its request the Trustee shall authenticate and
make available for delivery, in lieu of any such destroyed, lost or stolen
Security, a new Security of the same issue and series of like tenor and
principal amount, having the same Original Issue Date and Stated Maturity and
bearing the same interest rate as such destroyed, lost or stolen Security, and
bearing a number not contemporaneously outstanding.

         In case any such mutilated, destroyed, lost or stolen Security has
become or is about to become due and payable, the Company in its discretion may,
instead of issuing a new Security, pay such Security.

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

         Every new Security issued pursuant to this Section in lieu of any
destroyed, lost or stolen Security shall constitute an original additional
contractual obligation of the Company, whether or not the destroyed, lost or
stolen Security shall be at any time enforceable by anyone, and shall be
entitled to all the benefits of this Indenture equally and proportionately with
any and all other Securities of that series duly issued hereunder.



<PAGE>   37


                                                                              30



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

         SECTION 3.7.   Payment of Interest; Interest Rights Preserved.

         Interest on any Security of any series which is payable, and is
punctually paid or duly provided for, on any Interest Payment Date, shall be
paid to the Person in whose name that Security (or one or more Predecessor
Securities) is registered at the close of business on the Regular Record Date
for such interest in respect of Securities of such series, except that, unless
otherwise provided in the Securities of such series, interest payable on the
Stated Maturity of the principal of a Security shall be paid to the Person to
whom principal is paid. The initial payment of interest on any Security of any
series which is issued between a Regular Record Date and the related Interest
Payment Date shall be payable as provided in such Security or in the Board
Resolution pursuant to Section 3.1 with respect to the related series of
Securities. At the option of the Company, interest on any series of Securities
may be paid (i) by check mailed to the address of the Person entitled thereto as
it shall appear on the Securities Register of such series or (ii) by wire
transfer or direct deposit in immediately available funds at such place and to
such account as designated by the Person entitled thereto as specified in the
Securities Register of such series, provided that proper transfer instructions
have been received prior to the relevant Regular Record Date.

         Any interest on any Security which is payable, but is not timely paid
or duly provided for, on any Interest Payment Date for Securities of such series
(herein called "Defaulted Interest"), shall forthwith cease to be payable to the
registered Holder on the relevant Regular Record Date by virtue of having been
such Holder, and such Defaulted Interest may be paid by the Company, at its
election in each case, as provided in Clause (1) or (2) below:

         (1) The Company may elect to make payment of any Defaulted Interest to
the Persons in whose names the Securities of such series in respect of which
interest is in default (or their respective Predecessor Securities) are
registered at the close of business on a Special Record Date for the payment of
such Defaulted Interest, which shall be fixed in the following manner. The
Company shall notify the Trustee in writing of the amount of Defaulted Interest
proposed to be paid on each Security and the date of the proposed payment, and
at the same time the Company shall deposit with the Trustee an amount of money
equal to the aggregate amount proposed to be paid in respect of such Defaulted
Interest or shall make arrangements satisfactory to the Trustee for such deposit
prior to the date of the proposed payment, such money when deposited to be held
in trust for the benefit of the Persons entitled to such Defaulted Interest as
in this Clause provided. Thereupon the Trustee shall fix a Special Record Date
for the payment of such Defaulted Interest which shall be not more than 15 days
and not less than 10 days prior to the date of the proposed payment and not less
than 10 days after the receipt by the Trustee of the notice of the proposed
payment. The Trustee shall promptly notify the Company of such Special Record
Date and, in the name and at the expense of the Company, shall cause notice of
the proposed payment of such Defaulted Interest and the Special Record Date
therefor to be mailed, first class, postage prepaid, to each Holder of a
Security of such series at the address of such Holder as it appears in the
Securities Register not less than 10 days prior to such Special Record Date. The
Trustee may, in its discretion, in the name and at the expense of the


<PAGE>   38


                                                                              31



Company, cause a similar notice to be published at least once in a newspaper,
customarily published in the English language on each Business Day and of
general circulation in the Borough of Manhattan, The City of New York, but such
publication shall not be a condition precedent to the establishment of such
Special Record Date. Notice of the proposed payment of such Defaulted Interest
and the Special Record Date therefor having been mailed as aforesaid, such
Defaulted Interest shall be paid to the Persons in whose names the Securities of
such series (or their respective Predecessor Securities) are registered on such
Special Record Date and shall no longer be payable pursuant to the following
Clause (2).

         (2) The Company may make payment of any Defaulted Interest in any other
lawful manner not inconsistent with the requirements of any securities exchange
or automated quotation system on which the Securities of the series in respect
of which interest is in default may be listed or traded and, upon such notice as
may be required by such exchange (or by the Trustee if the Securities are not
listed), if, after notice given by the Company to the Trustee of the proposed
payment pursuant to this Clause, such payment shall be deemed practicable by the
Trustee.

         Any interest on any Security which is deferred or extended pursuant to
Section 3.11 shall not be Defaulted Interest for the purposes of this Section
3.7.

         Subject to the foregoing provisions of this Section, each Security
delivered under this Indenture upon transfer of or in exchange for or in lieu of
any other Security shall carry the rights to interest accrued and unpaid, and to
accrue, which were carried by such other Security.

         SECTION 3.8.   Persons Deemed Owners.

         The Company, the Trustee and any agent of the Company or the Trustee
may treat the Person in whose name any Security is registered as the owner of
such Security for the purpose of receiving payment of principal of and (subject
to Section 3.7) any interest on such Security and for all other purposes
whatsoever, whether or not such Security be overdue, and neither the Company,
the Trustee nor any agent of the Company or the Trustee shall be affected by
notice to the contrary.

         SECTION 3.9.   Cancellation.

         All Securities surrendered for payment, redemption, transfer or
exchange shall, if surrendered to any Person other than the Trustee, be
delivered to the Trustee, and any such Securities and Securities surrendered
directly to the Trustee for any such purpose shall be promptly canceled by it.
The Company may at any time deliver to the Trustee for cancellation any
Securities previously authenticated and delivered hereunder which the Company
may have acquired in any manner whatsoever, and all Securities so delivered
shall be promptly canceled by the Trustee. No Securities shall be authenticated
in lieu of or in exchange for any Securities canceled as provided in this
Section, except as expressly permitted by this Indenture. All canceled
Securities shall be returned by the Trustee to the Company and destroyed by the
Company.

         SECTION 3.10.   Computation of Interest.


<PAGE>   39


                                                                              32




         Except as otherwise specified as contemplated by Section 3.1 for
Securities of any series, interest on the Securities of each series for any
period shall be computed on the basis of a 360-day year of twelve 30-day months
and interest on the Securities of each series for any partial period shall be
computed on the basis of the number of days elapsed in a 360-day year of twelve
30-day months.

         SECTION 3.11.   Deferrals of Interest Payment Dates.

         If specified as contemplated by Section 2.1 or Section 3.1 with respect
to the Securities of a particular series, so long as no Event of Default has
occurred and is continuing, the Company shall have the right, at any time during
the term of such series, from time to time to defer the payment of interest on
such Securities for such period or periods as may be specified as contemplated
by Section 3.1 (each, an "Extension Period") during which Extension Periods the
Company shall have the right to make partial payments of interest on any
Interest Payment Date. No Extension Period shall end on a date other than an
Interest Payment Date. At the end of any such Extension Period the Company shall
pay all interest then accrued and unpaid on the Securities (together with
Additional Interest thereon, if any, at the rate specified for the Securities of
such series to the extent permitted by applicable law) to the Persons in whose
names that Securities are registered at the close of business on the Regular
Record Date with respect to the Interest Payment Date at the end of such
Extension Period; provided, however, that no Extension Period shall extend
beyond the Stated Maturity of the principal of the Securities of such series;
provided, further, that during any such Extension Period, the Company shall not,
and shall not permit any Subsidiary to, (i) declare or pay any dividends or
distributions on, or redeem, purchase, acquire or make a liquidation payment
with respect to, any of the Company's capital stock, (ii) make any payment of
principal of or interest or premium, if any, on or repay, repurchase or redeem
any debt security of the Company that ranks pari passu with or junior in
interest to the Securities of such series or (iii) make any guarantee payments
with respect to any guarantee by the Company of the debt securities of any
Subsidiary of the Company that by their terms rank pari passu with or junior in
interest to the securities of such series (other than (a) dividends or
distributions in the Company's capital stock, (b) any declaration of a dividend
in connection with the implementation of a Rights Plan, or the redemption or
repurchase of any rights distributed pursuant to a Rights Plan, (c) payments
under the Guarantee with respect to such Security, and (d) purchases of Common
Stock related to the issuance of Common Stock or rights or options under any of
the Company's benefit plans for its directors, officers, employees or other
persons within the definition of "employee" for purposes of a registration of
shares for an employee benefit plan of the Company, related to the issuance
of Common Stock or rights under a dividend reinvestment and stock purchase plan,
or related to the issuance of Common Stock (or securities convertible or
exchangeable for Common Stock) as consideration in an acquisition transaction
that was entered into prior to the commencement of such Extension Period). Prior
to the termination of any such Extension Period, the Company may further defer
the payment of interest, provided that no Extension Period shall exceed the
period or periods specified in such Securities or extend beyond the Stated
Maturity of the principal of such Securities. Upon termination of any Extension
Period and upon the payment of all accrued and unpaid interest and any
Additional Interest then due on any Interest Payment Date, the Company may elect
to begin a new Extension Period, subject to the above requirements. No interest
shall be due and payable during an Extension Period, except at the end thereof.
The Company shall give the Holders of the Securities of such series and the


<PAGE>   40


                                                                              33



Trustee written notice of its election to begin any such Extension Period at
least one Business Day prior to the next succeeding Interest Payment Date on
which interest on Securities of such series would be payable but for such
deferral or, with respect to the Securities of a series issued to a Trust, so
long as such Securities are held by such Trust, prior to the earlier of (i) the
next succeeding date on which Distributions on the Preferred Securities of such
Trust would be payable but for such deferral or (ii) the date the Administrative
Trustees of such Trust are required to give notice to any securities exchange or
other applicable self-regulatory organization or to holders of such Preferred
Securities of the record date or the date such Distributions are payable, but in
any event not less than one Business Day prior to such record date.

         The Trustee shall promptly give notice, in the name and at the expense
of the Company, of the Company's election to begin any such Extension Period to
the Holders of the Outstanding Securities of such series.

         SECTION 3.12.   Right of Set-Off.

         With respect to the Securities of a series issued to a Trust,
notwithstanding anything to the contrary in the Indenture, the Company shall
have the right to set-off any payment it is otherwise required to make
thereunder in respect of any such Security to the extent the Company has
theretofore made, or is concurrently on the date of such payment making, a
payment under the Guarantee relating to such Security or under Section 5.8 of
the Indenture.

         SECTION 3.13.   Agreed Tax Treatment.

         Each Security issued hereunder shall provide that the Company and, by
its acceptance of a Security or a beneficial interest therein, the Holder of,
and any Person that acquires a beneficial interest in, such Security intend that
such Security constitutes indebtedness and agree to treat such Security as
indebtedness for United States federal, local and state tax purposes.

         SECTION 3.14.   Shortening or Extension of Stated Maturity.

         If specified as contemplated by Section 2.1 or Section 3.1 with respect
to the Securities of a particular series, the Company shall have the right to
(i) shorten the Stated Maturity of the principal of the Securities of such
series at any time to any date not earlier than the first date on which the
Company has the right to redeem the Securities of such series, and (ii) extend
the Stated Maturity of the principal of the Securities of such series at any
time at its election for one or more periods, but in no event to a date later
than the 49th anniversary of the Original Issue Date of the Securities of such
series; provided that, if the Company elects to exercise its right to extend the
Stated Maturity of the principal of the Securities of such series pursuant to
clause (ii), above, at the time such election is made and at the time of
extension (A) the Company is not in bankruptcy, otherwise insolvent or in
liquidation, (B) the Company is not in default in the payment of any interest or
principal on such Securities, (C) in the case of any series of Securities held
by a Trust, such Trust is not in arrears on payments of Distributions on the
Preferred Securities issued by such Trust and no deferred Distributions are
accumulated, (D) such Securities are rated not less than BBB- by S&P or Baa3 by
Moody's or the equivalent by any other nationally recognized statistical rating
organization and (E) the Securities will not have a remaining period to maturity
of more than 30 years after such extension. In the event the

                                                                              34



Company elects to shorten or extend the Stated Maturity of any Securities, it
shall give written notice to the Trustee, and the Trustee shall give notice of
such shortening or extension to the Holders, no less than 30 and no more than
60 days prior to the effectiveness thereof.

         SECTION 3.15.   CUSIP Numbers.

         The Company in issuing the Securities may use "CUSIP" numbers (if then
generally in use), and, if so, the Trustee shall use "CUSIP" numbers in notices
of redemption as a convenience to Holders; provided that any such notice may
state that no representation is made as to the correctness of such numbers
either as printed on the Securities or as contained in any notice of a
redemption and that reliance may be placed only on the other identification
numbers printed on the Securities, and any such redemption shall not be affected
by any defect in or omission of such numbers. The Company will promptly notify
the Trustee of any change in the CUSIP numbers.



                                   ARTICLE IV

                           SATISFACTION AND DISCHARGE

         SECTION 4.1.   Satisfaction and Discharge of Indenture.

         This Indenture shall, upon Company Request, cease to be of further
effect (except as to any surviving rights of registration of transfer or
exchange of Securities herein expressly provided for and as otherwise provided
in this Section 4.1) and the Trustee, on demand of and at the expense of the
Company, shall execute proper instruments acknowledging satisfaction and
discharge of this Indenture, when

         (1) either

         (A) all Securities theretofore authenticated and delivered (other than
(i) Securities which have been destroyed, lost or stolen and which have been
replaced or paid as provided in Section 3.6 and (ii) Securities for whose
payment money has theretofore been deposited in trust or segregated and held in
trust by the Company and thereafter repaid to the Company or discharged from
such trust, as provided in Section 10.3) have been delivered to the Trustee for
cancellation; or

         (B) all such Securities not theretofore delivered to the Trustee for
cancellation

                        (i)   have become due and payable, or
                
                       (ii)   will become due and payable at their Stated
                              Maturity within one year of the date of deposit,
                              or



<PAGE>   42


                                                                              35



       (iii) are to be called for redemption within one year under arrangements
             satisfactory to the Trustee for the giving of notice of redemption
             by the Trustee in the name, and at the expense, of the Company,

             and the Company, in the case of  Clause (B) (i), (ii) or (iii)
             above, has deposited or caused to be deposited with the Trustee as
             trust funds in trust for such purpose an amount in the currency or
             currencies in which the Securities of such series are payable
             sufficient to pay and discharge the entire indebtedness on such
             Securities no theretofore delivered to the Trustee for
             cancellation, including principal (and premium, if any) and
             interest (including any Additional Interest) to the date of such
             deposit (in the case of Securities which have become due and
             payable) or to the Stated Maturity or Redemption Date, as the case
             may be;

         (2) the Company has paid or caused to be paid all other sums payable
hereunder by the Company; and

         (3) the Company has delivered to the Trustee an Officers' Certificate
and an Opinion of Counsel each stating that all conditions precedent herein
provided for relating to the satisfaction and discharge of this Indenture have
been complied with.

Notwithstanding the satisfaction and discharge of this Indenture, the
obligations of the Company to the Trustee under Section 6.7, the obligations of
the Company to any Authenticating Agent under Section 6.14 and, if money shall
have been deposited with the Trustee pursuant to subclause (B) of clause (1) of
this Section, the obligations of the Trustee under Section 4.2 and the last
paragraph of Section 10.3 shall survive.

         SECTION 4.2.   Application of Trust Money.

         Subject to the provisions of the last paragraph of Section 10.3, all
money deposited with the Trustee pursuant to Section 4.1 shall be held in trust
and applied by the Trustee, in accordance with the provisions of the Securities
and this Indenture, to the payment, either directly or through any Paying Agent
(including the Company acting as its own Paying Agent) as the Trustee may
determine, to the Persons entitled thereto, of the principal (and premium, if
any) and interest for the payment of which such money or obligations have been
deposited with or received by the Trustee.

                                    REMEDIES

         SECTION 5.1.   Events of Default.

         "Event of Default", wherever used herein with respect to the Securities
of any series, means any one of the following events (whatever the reason for
such Event of Default and whether it shall be voluntary or involuntary or be
effected by operation of law or pursuant to

                                                                              36



any judgment, decree or order of any court or any order, rule or regulation of
any administrative or governmental body):

         (1) default in the payment of any interest upon any Security of that
series, including any Additional Interest in respect thereof, when it becomes
due and payable, and continuance of such default for a period of 30 days
(subject to the deferral of any interest payment date in the case of an
Extension Period); or

         (2) default in the payment of the principal of (or premium, if any, on)
any Security of that series at its Maturity; or

         (3) default in the performance, or breach, in any material respect, of
any covenant or warranty of the Company in this Indenture with respect to that
series (other than a covenant or warranty a default in the performance of which
or the breach of which is elsewhere in this Section specifically dealt with),
and continuance of such default or breach for a period of 90 days after there
has been given, by registered or certified mail, to the Company by the Trustee
or to the Company and the Trustee by the Holders of at least 25% in principal
amount of the Outstanding Securities of that series a written notice specifying
such default or breach and requiring it to be remedied; or

         (4) the entry of a decree or order by a court having jurisdiction in
the premises adjudging the Company bankrupt or insolvent, or approving as
properly filed a petition seeking reorganization, arrangement, adjustment or
composition of or in respect of the Company under any applicable federal or
state bankruptcy, insolvency, reorganization or other similar law, or appointing
a receiver, liquidator, assignee, trustee, sequestrator (or other similar
official) of the Company or of any substantial part of its property or ordering
the winding up or liquidation of its affairs, and the continuance of any such
decree or order unstayed and in effect for a period of 60 consecutive days; or

         (5) the institution by the Company of proceedings to be adjudicated 
bankrupt or insolvent, or the consent by it to the institution of bankruptcy or
insolvency proceedings against it, or the filing by it of a petition or answer
or consent seeking reorganization or relief under any applicable federal or
state bankruptcy, insolvency, reorganization or other similar law, or the
consent by it to the filing of any such petition or to the appointment of a
receiver, liquidator, assignee, trustee, sequestrator (or other similar
official) of the Company or of any substantial part of its property, or the
making by it of an assignment for the benefit for creditors, or the admission by
it in writing of its inability to pay its debts generally as they become due and
its willingness to be adjudicated a bankrupt, or the taking of corporate action
by the Company in furtherance of any such action; or

         (6) any other Event of Default provided with respect to Securities of
that series.

         SECTION 5.2.   Acceleration of Maturity; Rescission and Annulment.

         If an Event of Default (other than an Event of Default specified in
Section 5.1(4) or 5.1(5)) with respect to Securities of any series at the time
Outstanding occurs and is continuing, then and in every such case the Trustee or
the Holders of not less than 25% in principal amount


<PAGE>   44


                                                                              37



of the Outstanding Securities of that series may declare the principal amount
(or, if the Securities of that series are Discount Securities, such portion of
the principal amount as may be specified in the terms of that series) of all the
Securities of that series to be due and payable immediately, by a notice in
writing to the Company (and to the Trustee if given by Holders), provided that,
in the case of the Securities of a series issued to a Trust, if, upon an Event
of Default, the Trustee or the Holders of not less than 25% in principal amount
of the Outstanding Securities of that series fail to declare the principal
amount (or, if the Securities of that series are Discount Securities, such
portion of the principal amount as may be specified in the terms of that series)
of all the Securities of that series to be immediately due and payable, the
holders of at least 25% in aggregate liquidation amount of the corresponding
series of Preferred Securities then outstanding shall have such right by a
notice in writing to the Company and the Trustee; and upon any such declaration
such principal amount (or specified portion thereof) of and the accrued interest
(including any Additional Interest) on all the Securities of such series shall
become immediately due and payable. Payment of principal and interest (including
any Additional Interest) on such Securities shall remain subordinated to the
extent provided in Article XIII notwithstanding that such amount shall become
immediately due and payable as herein provided. If an Event of Default specified
in Section 5.1(4) or 5.1(5) with respect to Securities of any series at the time
Outstanding occurs, the principal amount of all the Securities of that series
(or, if the Securities of that series are Discount Securities, such portion of
the principal amount of such Securities as may be specified by the terms of that
series) shall automatically, and without any declaration or other action on the
part of the Trustee or any Holder, become immediately due and payable.

         At any time after such a declaration of acceleration with respect to
Securities of any series has been made and before a judgment or decree for
payment of the money due has been obtained by the Trustee as hereinafter in this
Article provided, the Holders of a majority in principal amount of the
Outstanding Securities of that series, by written notice to the Company and the
Trustee, may rescind and annul such declaration and its consequences if:

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

         (A) all overdue installments of interest (including any Additional
Interest) on all Securities of that series,

         (B) the principal of (and premium, if any, on) any Securities of that
series which have become due otherwise than by such declaration of acceleration
and interest thereon at the rate borne by the Securities, and

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

         (2) all Events of Default with respect to Securities of that series,
other than the non-payment of the principal of Securities of that series which
has become due solely by such acceleration, have been cured or waived as
provided in Section 5.13;

provided that, in the case of Securities of a series held by a Trust, if the
Holders of at least a majority in principal amount of the Outstanding Securities
of that series fails to rescind and


<PAGE>   45


                                                                              38



annul such declaration and its consequences, the holders of a majority in
aggregate Liquidation Amount (as defined in the Trust Agreement under which such
Trust is formed) of the related series of Preferred Securities then outstanding
shall have such right by written notice to the Company and the Trustee, subject
to the satisfaction of the conditions set forth in Clauses (1) and (2) above of
this Section 5.2.

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

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

         The Company covenants that if:

         (1) default is made in the payment of any installment of interest
(including any Additional Interest) on any Security when such interest becomes
due and payable and such default continues for a period of 30 days, or

         (2) default is made in the payment of the principal of (and premium, if
any, on) any Security at the Maturity thereof, the Company will, upon demand of
the Trustee, pay to the Trustee, for the benefit of the Holders of such
Securities, the whole amount then due and payable on such Securities for
principal, including any sinking fund payment or analogous obligations (and
premium, if any) and interest (including any Additional Interest); and, in
addition thereto, all amounts owing the Trustee under Section 6.7.

         If the Company fails to pay such amounts forthwith upon such demand,
the Trustee, in its own name and as trustee of an express trust, may institute a
judicial proceeding for the collection of the sums so due and unpaid, and may
prosecute such proceeding to judgment or final decree, and may enforce the same
against the Company or any other obligor upon the Securities and collect the
moneys adjudged or decreed to be payable in the manner provided by law out of
the property of the Company or any other obligor upon the Securities, wherever
situated.

         If an Event of Default with respect to Securities of any series occurs
and is continuing, the Trustee may in its discretion proceed to protect and
enforce its rights and the rights of the Holders of Securities of such series by
such appropriate judicial proceedings as the Trustee shall deem most effectual
to protect and enforce any such rights, whether for the specific enforcement of
any covenant or agreement in this Indenture or in aid of the exercise of any
power granted herein, or to enforce any other proper remedy.

         SECTION 5.4.   Trustee May File Proofs of Claim.

         In case of the pendency of any receivership, insolvency, liquidation,
bankruptcy, reorganization, arrangement, adjustment, composition or other
judicial proceeding relative to the Company or any other obligor upon the
Securities or the property of the Company or of such other obligor or their
creditors,


<PAGE>   46


                                                                              39




         (a) the Trustee (irrespective of whether the principal of the
Securities of any series shall then be due and payable as therein expressed or
by declaration of acceleration or otherwise and irrespective of whether the
Trustee shall have made any demand on the Company for the payment of overdue
principal (and premium, if any) or interest (including any Additional Interest))
shall be entitled and empowered, by intervention in such proceeding or
otherwise,

         (i) to file and prove a claim for the whole amount of principal (or, if
the Securities of that series are Discount Securities, such portion of the
principal amount as may be due and payable pursuant to a declaration in
accordance with Section 5.2) (and premium, if any) and interest (including any
Additional Interest) owing and unpaid in respect to the Securities and to file
such other papers or documents as may be necessary or advisable and to take any
and all actions as are authorized under the Trust Indenture Act in order to have
the claims of the Holders and any predecessor to the Trustee under Section 6.7
allowed in any such judicial proceedings; and

         (ii) in particular, the Trustee shall be authorized to collect and
receive any moneys or other property payable or deliverable on any such claims
and to distribute the same in accordance with Section 5.6; and

         (b) any custodian, receiver, assignee, trustee, liquidator,
sequestrator (or other similar official) in any such judicial proceeding is
hereby authorized by each Holder to make such payments to the Trustee for
distribution in accordance with Section 5.6, and in the event that the Trustee
shall consent to the making of such payments directly to the Holders, to pay to
the Trustee any amount due to it and any predecessor Trustee under Section 6.7.

         Nothing herein contained shall be deemed to authorize the Trustee to
authorize or consent to or accept or adopt on behalf of any Holder any plan of
reorganization, arrangement, adjustment or composition affecting the Securities
or the rights of any Holder thereof, or to authorize the Trustee to vote in
respect of the claim of any Holder in any such proceeding; provided, however,
that the Trustee may, on behalf of the Holders, vote for the election of a
trustee in bankruptcy or similar official and be a member of a creditors' or
other similar committee.

         SECTION 5.5. Trustee May Enforce Claims Without Possession of
Securities.

         All rights of action and claims under this Indenture or the Securities
may be prosecuted and enforced by the Trustee without the possession of any of
the Securities or the production thereof in any proceeding relating thereto, and
any such proceeding instituted by the Trustee shall be brought in its own name
as trustee of an express trust, and any recovery of judgment shall, after
provision for the payment of all the amounts owing the Trustee and any
predecessor Trustee under Section 6.7, its agents and counsel, be for the
ratable benefit of the Holders of the Securities in respect of which such
judgment has been recovered.

         SECTION 5.6.   Application of Money Collected.

         Any money or property collected or to be applied by the Trustee with
respect to a series of Securities pursuant to this Article shall be applied in
the following order, at the date or dates


<PAGE>   47


                                                                              40



fixed by the Trustee and, in case of the distribution of such money or property
on account of principal (or premium, if any) or interest (including any
Additional Interest), upon presentation of the Securities and the notation
thereon of the payment if only partially paid and upon surrender thereof if
fully paid:

         FIRST: To the payment of all amounts due the Trustee and any
predecessor Trustee under Section 6.7;

         SECOND: Subject to Article XIII, to the payment of the amounts then due
and unpaid upon such series of Securities for principal (and premium, if any),
interest (including any Additional Interest) and Additional Taxes, in respect of
which or for the benefit of which such money has been collected, ratably,
without preference or priority of any kind, according to the amounts due and
payable on such series of Securities for principal (and premium, if any) and
interest (including any Additional Interest), respectively; and

         THIRD: The balance, if any, to the Person or Persons entitled thereto.

         SECTION 5.7.   Limitation on Suits.

         No Holder of any Securities of any series shall have any right to
institute any proceeding, judicial or otherwise, with respect to this Indenture
or for the appointment of a receiver, assignee, trustee, liquidator,
sequestrator (or other similar official) or for any other remedy hereunder,
unless:

         (1) such Holder has previously given written notice to the Trustee of a
continuing Event of Default with respect to the Securities of that series;

         (2) the Holders of not less than 25% in principal amount of the
Outstanding Securities of that series shall have made written request to the
Trustee to institute proceedings in respect of such Event of Default in its own
name as Trustee hereunder;

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

         (4) the Trustee for 60 days after its receipt of such notice, request
and offer of security or indemnity has failed to institute any such proceeding;
and

         (5) no direction inconsistent with such written request has been given
to the Trustee during such 60-day period by the Holders of a majority in
principal amount of the Outstanding Securities of that series;

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

                                                                              41




         SECTION 5.8. Unconditional Right of Holders to Receive Principal,
Premium and Interest; Direct Action by Holders of Preferred Securities.

         Notwithstanding any other provision in this Indenture, the Holder of
any Security shall have the right which is absolute and unconditional to receive
payment of the principal of (and premium, if any) and (subject to Section 3.7)
interest (including any Additional Interest) on such Security on the respective
Stated Maturities expressed in such Security (or, in the case of redemption, on
the Redemption Date) and to institute suit for the enforcement of any such
payment, and such right shall not be impaired without the consent of such
Holder. In the case of Securities of a series held by a Trust, any holder of the
corresponding series of Preferred Securities held by such Trust shall have the
right, upon the occurrence of an Event of Default described in Section 5.1(1) or
5.1(2), to institute a suit directly against the Company for enforcement of
payment to such holder of principal of (premium, if any) and (subject to Section
3.7) interest (including any Additional Interest) on the Securities having a
principal amount equal to the aggregate Liquidation Amount (as defined in the
Trust Agreement under which such Trust is formed) of such Preferred Securities
of the corresponding series held by such holder.

         SECTION 5.9.   Restoration of Rights and Remedies.

         If the Trustee, any Holder or any holder of Preferred Securities has
instituted any proceeding to enforce any right or remedy under this Indenture
and such proceeding has been discontinued or abandoned for any reason, or has
been determined adversely to the Trustee, such Holder or such holder of
Preferred Securities, then and in every such case the Company, the Trustee, the
Holders and such holder of Preferred Securities shall, subject to any
determination in such proceeding, be restored severally and respectively to
their former positions hereunder, and thereafter all rights and remedies of the
Trustee, the Holders and the holders of Preferred Securities shall continue as
though no such proceeding had been instituted.

         SECTION 5.10.   Rights and Remedies Cumulative.

         Except as otherwise provided in the last paragraph of Section 3.6, no
right or remedy herein conferred upon or reserved to the Trustee or to the
Holders is intended to be exclusive of any other right or remedy, and every
right and remedy shall, to the extent permitted by law, be cumulative and in
addition to every other right and remedy given hereunder or now or hereafter
existing at law or in equity or otherwise. The assertion or employment of any
right or remedy hereunder, or otherwise, shall not prevent the concurrent
assertion or employment of any other appropriate right or remedy.

         SECTION 5.11.   Delay or Omission Not Waiver.

         No delay or omission of the Trustee, any Holder of any Security or any
holder of any Preferred Security to exercise any right or remedy accruing upon
any Event of Default shall impair any such right or remedy or constitute a
waiver of any such Event of Default or an acquiescence therein.

         Every right and remedy given by this Article or by law to the Trustee
or to the Holders and the right and remedy given to the holders of Preferred
Securities by Section 5.8 may be


<PAGE>   49


                                                                              42



exercised from time to time, and as often as may be deemed expedient, by the
Trustee, the Holders or the holders of Preferred Securities, as the case may be.

         SECTION 5.12.   Control by Holders.

         The Holders of a majority in principal amount of the Outstanding
Securities of any series shall have the right to direct the time, method and
place of conducting any proceeding for any remedy available to the Trustee or
exercising any trust or power conferred on the Trustee, with respect to the
Securities of such series, provided that:

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

         (2) the Trustee may take any other action deemed proper by the Trustee
which is not inconsistent with such direction, and

         (3) subject to the provisions of Section 6.1, the Trustee shall have
the right to decline to follow such direction if a Responsible Officer or
Officers of the Trustee shall, in good faith, determine that the proceeding so
directed would be unjustly prejudicial to the Holders not joining in any such
direction or would involve the Trustee in personal liability.

         SECTION 5.13.   Waiver of Past Defaults.

         The Holders of not less than a majority in principal amount of the
Outstanding Securities of any series and, in the case of any Securities of a
series issued to a Trust, the holders of a majority in Liquidation Amount (as
defined in the relevant Trust Agreement) of Preferred Securities issued by such
Trust may waive any past default hereunder and its consequences with respect to
such series except a default:

         (1) in the payment of the principal of (or premium, if any) or interest
(including any Additional Interest) on any Security of such series (unless all
Events of Default with respect to Securities of that series, other than the
non-payment of the principal of Securities of that series which has become due
solely by acceleration, have been cured or annulled as provided in Section
5.3 and the Company has paid or deposited with the Trustee a sum sufficient to
pay all overdue installments of interest (including any Additional Interest) on
all Securities of that series, the principal of (and premium, if any, on) any
Securities of that series which have become due otherwise than by such
declaration of acceleration and interest thereon at the rate borne by the
Securities, and all sums paid or advanced by the Trustee hereunder and the
reasonable compensation, expenses, disbursements and advances of the Trustee,
its agents and counsel), or

         (2) in respect of a covenant or provision hereof which under Article IX
cannot be modified or amended without the consent of the Holder of each
Outstanding Security of such series affected.

         Any such waiver shall be deemed to be on behalf of the Holders of all
the Securities of such series or, in the case of a waiver by holders of
Preferred Securities issued by such Trust, by all holders of Preferred
Securities issued by such Trust.



<PAGE>   50


                                                                              43



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

         SECTION 5.14.   Undertaking for Costs.

         All parties to this Indenture agree, and each Holder of any Security by
his acceptance thereof shall be deemed to have agreed, that any court may in its
discretion require, in any suit for the enforcement of any right or remedy under
this Indenture, or in any suit against the Trustee for any action taken or
omitted by it as Trustee, the filing by any party litigant in such suit of an
undertaking to pay the costs of such suit, and that such court may in its
discretion assess reasonable costs, including reasonable attorneys' fees and
expenses, against any party litigant in such suit, having due regard to the
merits and good faith of the claims or defenses made by such party litigant; but
the provisions of this Section shall not apply to any suit instituted by the
Trustee, to any suit instituted by any Holder, or group of Holders, holding in
the aggregate more than 10% in principal amount of the Outstanding Securities of
any series, or to any suit instituted by any Holder for the enforcement of the
payment of the principal of (or premium, if any) or interest (including any
Additional Interest) on any Security on or after the respective Stated
Maturities expressed in such Security.

         SECTION 5.15.   Waiver of Usury, Stay or Extension Laws.

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


                                   ARTICLE VI

                                   THE TRUSTEE

         SECTION 6.1.   Certain Duties and Responsibilities.

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

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

         (2) in the absence of bad faith on its part, the Trustee may
conclusively rely, as to the truth of the statements and the correctness of the
opinions expressed therein, upon certificates or opinions furnished to the
Trustee and conforming to the requirements of this Indenture; but


<PAGE>   51


                                                                              44



in the case of any such certificates or opinions which by any provisions hereof
are specifically required to be furnished to the Trustee, the Trustee shall be
under a duty to examine the same to determine whether or not they conform to the
requirements of this Indenture.

         (b) In case an Event of Default has occurred and is continuing, the
Trustee shall exercise such of the rights and powers vested in it by this
Indenture, 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
his own affairs.

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

         (1) this Subsection shall not be construed to limit the effect of
Subsection (a) of this Section;

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

         (3) the Trustee shall not be liable with respect to any action taken or
omitted to be taken by it in good faith in accordance with the direction of
Holders pursuant to Section 5.12 relating to the time, method and place of
conducting any proceeding for any remedy available to the Trustee, or exercising
any trust or power conferred upon the Trustee, under this Indenture with respect
to the Securities of such series.

         (d) No provision of this Indenture shall require the Trustee to expend
or risk its own funds or otherwise incur any financial liability in the
performance of any of its duties hereunder, or in the exercise of any of its
rights or powers, if there shall be reasonable grounds for believing that
repayment of such funds or adequate indemnity against such risk or liability is
not reasonably assured to it.

         (e) Whether or not therein expressly so provided, every provision of
this Indenture relating to the conduct or affecting the liability of or
affording protection to the Trustee shall be subject to the provisions of this
Section.

         SECTION 6.2.   Notice of Defaults.

         Within 90 days after actual knowledge by a Responsible Officer of the
Trustee of the occurrence of any default hereunder with respect to the
Securities of any series, the Trustee shall transmit by mail to all Holders of
Securities of such series, as their names and addresses appear in the Securities
Register, notice of such default, unless such default shall have been cured or
waived; provided, however, that, except in the case of a default in the payment
of the principal of (or premium, if any) or interest (including any Additional
Interest) on any Security of such series, the Trustee shall be protected in
withholding such notice if and so long as the board of directors, the executive
committee or a trust committee of directors and/or Responsible Officers of the
Trustee in good faith determines that the withholding of such notice is in the
interests of

the Holders of Securities of such series; and provided, further, that, in the
case of any default of the character specified in Section 5.1(3), no such notice
to Holders of Securities of such series shall be given until at least 30 days
after the occurrence thereof. For the purpose of this Section, the term

         Subject to the provisions of Section 6.1:

be herein specifically prescribed) may, in the absence of bad faith on its part,
rely upon an Officers' Certificate;

         (d) the Trustee may consult with counsel of its selection and the

expenses and liabilities which might be incurred by it in compliance with such
request or direction;

         (f) the Trustee shall not be bound to make any investigation into the

                                                                              46



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

         SECTION 6.4.   Not Responsible for Recitals or Issuance of Securities.

         The recitals contained herein and in the Securities, except the
Trustee's certificates of authentication, shall be taken as the statements of
the Company, and neither the Trustee nor any Authenticating Agent assumes any
responsibility for their correctness. The Trustee makes no representations as to
the validity or sufficiency of this Indenture or of the Securities. Neither the
Trustee nor any Authenticating Agent shall be accountable for the use or
application by the Company of the Securities or the proceeds thereof.

         SECTION 6.5.   May Hold Securities.

         The Trustee, any Authenticating Agent, any Paying Agent, any Securities
Registrar or any other agent of the Company, in its individual or any other
capacity, may become the owner or pledgee of Securities and, subject to Sections
6.8 and 6.13, may otherwise deal with the Company with the same rights it would
have if it were not Trustee, Authenticating Agent, Paying Agent, Securities
Registrar or such other agent.

         SECTION 6.6.   Money Held in Trust.

         Money held by the Trustee in trust hereunder need not be segregated
from other funds except to the extent required by law. The Trustee shall be
under no liability for interest on any money received by it hereunder except as
otherwise agreed in writing with the Company.

         SECTION 6.7.   Compensation and Reimbursement.

         The Company, as borrower, agrees

         (1) to pay to the Trustee from time to time such compensation as shall
be agreed in writing between the Company and the Trustee for all services
rendered by it hereunder (which compensation shall not be limited by any
provision of law in regard to the compensation of a trustee of an express
trust);

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

         (3) to indemnify each of the Trustee and any predecessor Trustee for,
and to hold it harmless against, any and all loss, liability, damage, claim or
expense (including the reasonable compensation and the expenses and
disbursements of its agents and counsel) incurred without negligence or bad
faith, arising out of or in connection with the acceptance or administration of
this trust or the performance of its duties hereunder, including the costs and
expenses of


<PAGE>   54


                                                                              47



defending itself against any claim or liability in connection with the exercise
or performance of any of its powers or duties hereunder. This indemnification
shall survive the termination of this Agreement.

         To secure the Company's payment obligations in this Section, the
Company and the Holders agree that the Trustee shall have a lien prior to the
Securities on all money or property held or collected by the Trustee. Such lien
shall survive the satisfaction and discharge of this Indenture.

         When the Trustee incurs expenses or renders services after an Event of
Default specified in Section 5.1(4) or (5) occurs, the expenses and the
compensation for the services are intended to constitute expenses of
administration under the Bankruptcy Reform Act of 1978 or any successor statute.

         SECTION 6.8.   Disqualification; Conflicting Interests.

         The Trustee for the Securities of any series issued hereunder shall be
subject to the provisions of Section 310(b) of the Trust Indenture Act. Nothing
herein shall prevent the Trustee from filing with the Commission the application
referred to in the second to last paragraph of said Section 310(b).

         SECTION 6.9.   Corporate Trustee Required; Eligibility.

         There shall at all times be a Trustee hereunder which shall be

         (a) a corporation organized and doing business under the laws of the
United States of America or of any state or territory or the District of
Columbia, authorized under such laws to exercise corporate trust powers and
subject to supervision or examination by federal, state, territorial or District
of Columbia authority, or

         (b) a corporation or other Person organized and doing business under
the laws of a foreign government that is permitted to act as Trustee pursuant to
a rule, regulation or order of the Commission, authorized under such laws to
exercise corporate trust powers, and subject to supervision or examination by
authority of such foreign government or a political subdivision thereof
substantially equivalent to supervision or examination applicable to United
States institutional trustees,

in either case having a combined capital and surplus of at least $50,000,000,
subject to supervision or examination by federal or state authority. If such
corporation publishes reports of condition at least annually, pursuant to law or
to the requirements of the aforesaid supervising or examining authority, then,
for the purposes of this Section, the combined capital and surplus of such
corporation shall be deemed to be its combined capital and surplus as set forth
in its most recent report of condition so published. If at any time the Trustee
shall cease to be eligible in accordance with the provisions of this Section, it
shall resign immediately in the manner and with the effect hereinafter specified
in this Article. Neither the Company nor any Person directly or indirectly
controlling, controlled by or under common control with the Company shall serve
as Trustee for the Securities of any series issued hereunder.

         SECTION 6.10.   Resignation and Removal; Appointment of Successor.

         (a) No resignation or removal of the Trustee and no appointment of a
successor Trustee pursuant to this Article shall become effective until the
acceptance of appointment by the successor Trustee under Section 6.11.

         (b) The Trustee may resign at any time with respect to the Securities
of one or more series by giving written notice thereof to the Company. If an
instrument of acceptance by a successor Trustee shall not have been delivered to
the Trustee within 30 days after the giving of such notice of resignation, the
resigning Trustee may petition any court of competent jurisdiction for the
appointment of a successor Trustee with respect to the Securities of such
series.

         (c) The Trustee may be removed at any time with respect to the
Securities of any series by Act of the Holders of a majority in principal amount
of the Outstanding Securities of such series, delivered to the Trustee and to
the Company. If an instrument of acceptance by a successor Trustee shall not
have been delivered to the Trustee within 30 days after such removal, the
Trustee being removed may petition any court of competent jurisdiction for the
appointment of a successor Trustee with respect to the Securities of such
series.

         (d)   If at any time:

         (1) the Trustee shall fail to comply with Section 6.8 after written
request therefor by the Company or by any Holder who has been a bona fide Holder
of a Security for at least six months, or

         (2) the Trustee shall cease to be eligible under Section 6.9 and shall
fail to resign after written request therefor by the Company or by any such
Holder, or

         (3) 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,

then, in any such case, (i) the Company, acting pursuant to the authority of a
Board Resolution, may remove the Trustee with respect to all Securities, or (ii)
subject to Section 5.14, any Holder who has been a bona fide Holder of a
Security for at least six months may, on behalf of himself and all others
similarly situated, petition any court of competent jurisdiction for the removal
of the Trustee with respect to all Securities and the appointment of a successor
Trustee or Trustees.


         (e) If the Trustee shall resign, be removed or become incapable of
acting, or if a vacancy shall occur in the office of Trustee for any cause with
respect to the Securities of one or more series, the Company, by a Board
Resolution, shall promptly appoint a successor Trustee with respect to the
Securities of that or those series. If, within one year after such resignation,
removal or incapability, or the occurrence of such vacancy, a successor Trustee
with respect to the Securities of any series shall be appointed by Act of the
Holders of a majority in principal


<PAGE>   56


                                                                              49



amount of the Outstanding Securities of such series delivered to the Company and
the retiring Trustee, the successor Trustee so appointed shall, forthwith upon
its acceptance of such appointment, become the successor Trustee with respect to
the Securities of such series and supersede the successor Trustee appointed by
the Company. If no successor Trustee with respect to the Securities of any
series shall have been so appointed by the Company or the Holders and accepted
appointment in the manner hereinafter provided, any Holder who has been a bona
fide Holder of a Security for at least six months may, subject to Section 5.14,
on behalf of himself and all others similarly situated, petition any court of
competent jurisdiction for the appointment of a successor Trustee with respect
to the Securities of such series.

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

         SECTION 6.11.   Acceptance of Appointment by Successor.

         (a) In case of the appointment hereunder of a successor Trustee with
respect to all Securities, every such successor Trustee so appointed shall
execute, acknowledge and deliver to the Company and to the retiring Trustee an
instrument accepting such appointment, and thereupon the resignation or removal
of the retiring Trustee shall become effective and such successor Trustee,
without any further act, deed or conveyance, shall become vested with all the
rights, powers, trusts and duties of the retiring Trustee; but, on the request
of the Company or the successor Trustee, such retiring Trustee shall, upon
payment of its charges, execute and deliver an instrument transferring to such
successor Trustee all the rights, powers and trusts of the retiring Trustee and
shall duly assign, transfer and deliver to such successor Trustee all property
and money held by such retiring Trustee hereunder.

         (b) In case of the appointment hereunder of a successor Trustee with
respect to the Securities of one or more (but not all) series, the Company, the
retiring Trustee and each successor Trustee with respect to the Securities of
one or more series shall execute and deliver an indenture supplemental hereto
wherein each successor Trustee shall accept such appointment and which (1) shall
contain such provisions as shall be necessary or desirable to transfer and
confirm to, and to vest in, each successor Trustee all the rights, powers,
trusts and duties of the retiring Trustee with respect to the Securities of that
or those series to which the appointment of such successor Trustee relates, (2)
if the retiring Trustee is not retiring with respect to all Securities, shall
contain such provisions as shall be deemed necessary or desirable to confirm
that all the rights, powers, trusts and duties of the retiring Trustee with
respect to the Securities of that or those series as to which the retiring
Trustee is not retiring shall continue to be vested in the retiring Trustee, and
(3) shall add to or change any of the provisions of this Indenture as shall be
necessary to provide for or facilitate the administration of the trusts
hereunder by more than one Trustee, it being understood that nothing herein or
in such supplemental indenture shall constitute such Trustees co-trustees of the
same trust and that each such Trustee shall be trustee of a trust or trusts
hereunder separate and apart from any trust or trusts hereunder administered by
any other such Trustee; and upon the execution and delivery of such supplemental
indenture


<PAGE>   57


                                                                              50



the resignation or removal of the retiring Trustee shall become effective to the
extent provided therein and each such successor Trustee, without any further
act, deed or conveyance, shall become vested with all the rights, powers,
trusts, and duties of the retiring Trustee with respect to the Securities of
that or those series to which the appointment of such successor Trustee relates;
but, on request of the Company or any successor Trustee, such retiring Trustee
shall duly assign, transfer and deliver to such successor Trustee all property
and money held by such retiring Trustee hereunder with respect to the Securities
of that or those series to which the appointment of such successor Trustee
relates.

         (c) Upon request of any such successor Trustee, the Company shall
execute any and all instruments for more fully and certainly vesting in and
confirming to such successor Trustee all rights, powers and trusts referred to
in paragraph (a) or (b) of this Section, as the case may be.

         (d) No successor Trustee shall accept its appointment unless at the
time of such acceptance such successor Trustee shall be qualified and eligible
under this Article.

         SECTION 6.12. Merger, Conversion, Consolidation or Succession to
Business.

         Any corporation into which the Trustee may be merged or converted or
with which it may be consolidated, or any corporation resulting from any merger,
conversion or consolidation to which the Trustee shall be a party, or any
corporation succeeding to all or substantially all of the corporate trust
business of the Trustee, shall be the successor of the Trustee hereunder,
provided such corporation shall be otherwise qualified and eligible under this
Article, without the execution or filing of any paper or any further act on the
part of any of the parties hereto. In case any Securities shall have been
authenticated, but not delivered, by the Trustee then in office, any successor
by merger, conversion or consolidation to such authenticating Trustee may adopt
such authentication and deliver the Securities so authenticated, and in case any
Securities shall not have been authenticated, any successor to the Trustee may
authenticate such Securities either in the name of any predecessor Trustee or in
the name of such successor Trustee, and in all cases the certificate of
authentication shall have the full force which it is provided anywhere in the
Securities or in this Indenture that the certificate of the Trustee shall have.

         SECTION 6.13.   Preferential Collection of Claims Against Company.

         If and when the Trustee shall be or become a creditor of the Company
(or any other obligor upon the Securities), the Trustee shall be subject to the
provisions of the Trust Indenture Act regarding the collection of claims against
the Company (or any such other obligor).

         SECTION 6.14.   Appointment of Authenticating Agent.

         The Trustee may appoint an Authenticating Agent or Agents with respect
to one or more series of Securities which shall be authorized to act on behalf
of the Trustee to authenticate Securities of such series issued upon original
issue and upon exchange, registration of transfer or partial redemption thereof
or pursuant to Section 3.6, and Securities so authenticated shall be entitled to
the benefits of this Indenture and shall be valid and obligatory for all
purposes as if authenticated by the Trustee hereunder. Wherever reference is
made in this Indenture to the authentication and delivery of Securities by the
Trustee or the Trustee's certificate of


<PAGE>   58


                                                                              51



authentication, such reference shall be deemed to include authentication and
delivery on behalf of the Trustee by an Authenticating Agent. Each
Authenticating Agent shall be acceptable to the Company and shall at all times
be a corporation organized and doing business under the laws of the United
States of America, or of any state or territory or the District of Columbia,
authorized under such laws to act as Authenticating Agent, having a combined
capital and surplus of not less than $50,000,000 and subject to supervision or
examination by federal or state authority. If such Authenticating Agent
publishes reports of condition at least annually, pursuant to law or to the
requirements of said supervising or examining authority, then for the purposes
of this Section the combined capital and surplus of such Authenticating Agent
shall be deemed to be its combined capital and surplus as set forth in its most
recent report of condition so published. If at any time an Authenticating Agent
shall cease to be eligible in accordance with the provisions of this Section,
such Authenticating Agent shall resign immediately in the manner and with the
effect specified in this Section.

         Any corporation into which an Authenticating Agent may be merged or
converted or with which it may be consolidated, or any corporation resulting
from any merger, conversion or consolidation to which such Authenticating Agent
shall be a party, or any corporation succeeding to all or substantially all of
the corporate trust business of an Authenticating Agent shall be the successor
Authenticating Agent hereunder, provided such corporation shall be otherwise
eligible under this Section, without the execution or filing of any paper or any
further act on the part of the Trustee or the Authenticating Agent.

         An Authenticating Agent may resign at any time by giving written notice
thereof to the Trustee and to the Company. The Trustee may at any time terminate
the agency of an Authenticating Agent by giving written notice thereof to such
Authenticating Agent and to the Company. Upon receiving such a notice of
resignation or upon such a termination, or in case at any time such
Authenticating Agent shall cease to be eligible in accordance with the
provisions of this Section, the Trustee may appoint a successor Authenticating
Agent which shall be acceptable to the Company and shall give notice of such
appointment in the manner provided in Section 1.6 to all Holders of Securities
of the series with respect to which such Authenticating Agent will serve. Any
successor Authenticating Agent upon acceptance of its appointment hereunder
shall become vested with all the rights, powers and duties of its predecessor
hereunder, with like effect as if originally named as an Authenticating Agent.
No successor Authenticating Agent shall be appointed unless eligible under the
provision of this Section.

         The Company agrees to pay to each Authenticating Agent from time to
time reasonable compensation for its services under this Section.

         If an appointment with respect to one or more series is made pursuant
to this Section, the Securities of such series may have endorsed thereon, in
addition to the Trustee's certificate of authentication, an alternative
certificate of authentication in the following form:

         This is one of the Securities referred to in the within mentioned
Indenture.

         SECTION 7.3.   Reports by Trustee.

         (a) The Trustee shall transmit to Holders such reports concerning the
Trustee and its actions under this Indenture as may be required pursuant to the
Trust Indenture Act at the times and in the manner provided pursuant thereto. If
required by Section 313(a) of the Trust Indenture Act, the Trustee shall, within
sixty days after each May 15 following the date of this Indenture deliver to
Holders a brief report, dated as of such May 15, which complies with the

         (b) A copy of each such report shall, at the time of such transmission

Company or convey, transfer or lease its properties and assets substantially as
an entirety to the Company, unless:

                                                                              54



         (1) in case the Company shall consolidate with or merge into another
Person or convey, transfer or lease its properties and assets substantially as
an entirety to any Person, the Person formed by such consolidation or into which
the Company is merged or the Person which acquires by conveyance or transfer, or
which leases, the properties and assets of the Company substantially as an
entirety shall be a corporation, partnership or trust organized and existing
under the laws of the United States of America or any State or the District of
Columbia and shall expressly assume, by an indenture supplemental hereto,
executed and delivered to the Trustee, in form satisfactory to the Trustee, the
due and punctual payment of the principal of (and premium, if any) and interest
(including any Additional Interest) on all the Securities and the performance of
every covenant of this Indenture on the part of the Company to be performed or
observed;

         (2) immediately after giving effect to such transaction, no Event of
Default, and no event which, after notice or lapse of time, or both, would
become an Event of Default, shall have happened and be continuing;

         (3) in the case of the Securities of a series held by a Trust, such
consolidation, merger, conveyance, transfer or lease is permitted under the
related Trust Agreement and Guarantee and does not give rise to any breach or
violation of the related Trust Agreement or Guarantee; and

         (4) the Company has delivered to the Trustee an Officers' Certificate
and an Opinion of Counsel, each stating that such consolidation, merger,
conveyance, transfer or lease and any such supplemental indenture complies with
this Article and that all conditions precedent herein provided for relating to
such transaction have been complied with; and the Trustee, subject to Section
6.1, may rely upon such Officers' Certificate and Opinion of Counsel as
conclusive evidence that such transaction complies with this Section 8.1.

         SECTION 8.2.   Successor Corporation Substituted.

         Upon any consolidation or merger by the Company with or into any other
Person, or any conveyance, transfer or lease by the Company of its properties
and assets substantially as an entirety to any Person in accordance with Section
8.1, the successor Person formed by such consolidation or into which the Company
is merged or to which such conveyance, transfer or lease is made shall succeed
to, and be substituted for, and may exercise every right and power of, the
Company under this Indenture with the same effect as if such successor Person
had been named as the Company herein; and in the event of any such conveyance,
transfer or lease the Company shall be discharged from all obligations and
covenants under the Indenture and the Securities and may be dissolved and
liquidated.

         Such successor Person may cause to be signed, and may issue either in
its own name or in the name of the Company, any or all of the Securities
issuable hereunder which theretofore shall not have been signed by the Company
and delivered to the Trustee; and, upon the written order of such successor
Person instead of the Company and subject to all the terms, conditions and
limitations in this Indenture prescribed, the Trustee shall authenticate and
shall make available for delivery any Securities which previously shall have
been signed and delivered by the officers of the Company to the Trustee for
authentication pursuant to such provisions and any Securities which such
successor Person thereafter shall cause to be signed and delivered to


<PAGE>   62


                                                                              55



the Trustee on its behalf for the purpose pursuant to such provisions. All the
Securities so issued shall in all respects have the same legal rank and benefit
under this Indenture as the Securities theretofore or thereafter issued in
accordance with the terms of this Indenture as though all of such Securities had
been issued at the date of the execution hereof.

         In case of any such consolidation, merger, sale, conveyance or lease,
such changes in phraseology and form may be made in the Securities thereafter to
be issued as may be appropriate.


                                   ARTICLE IX

                             SUPPLEMENTAL INDENTURES

         SECTION 9.1.   Supplemental Indentures without Consent of Holders.

         Without the consent of any Holders, the Company, when authorized by a
Board Resolution, and the Trustee, at any time and from time to time, may enter
into one or more indentures supplemental hereto, in form reasonably satisfactory
to the Trustee, for any of the following purposes:

         (1) to evidence the succession of another Person to the Company, and
the assumption by any such successor of the covenants of the Company herein and
in the Securities contained; or

         (2) to convey, transfer, assign, mortgage or pledge any property to or
with the Trustee or to surrender any right or power herein conferred upon the
Company; or

         (3) to establish the form or terms of Securities of any series as
permitted by Sections 2.1 or 3.1; or

         (4) to add to the covenants of the Company for the benefit of the
Holders of all or any series of Securities (and if such covenants are to be for
the benefit of less than all series of Securities, stating that such covenants
are expressly being included solely for the benefit of such series) or to
surrender any right or power herein conferred upon the Company; or

         (5) to add any additional Events of Default for the benefit of the
Holders of all or any series of Securities (and if such additional Events of
Default are to be for the benefit of less than all series of Securities, stating
that such additional Events of Default are expressly being included solely for
the benefit of such series); or

         (6) to change or eliminate any of the provisions of this Indenture,
provided that any such change or elimination shall become effective only when
there is no Security Outstanding of any series created prior to the execution of
such supplemental indenture which is entitled to the benefit of such provision;
or

         (7) to cure any ambiguity, to correct or supplement any provision
herein which may be defective or inconsistent with any other provision herein,
or to make any other provisions with


<PAGE>   63


                                                                              56



respect to matters or questions arising under this Indenture, provided that such
action pursuant to this clause (7) shall not adversely affect the interest of
the Holders of Securities of any series in any material respect or, in the case
of the Securities of a series issued to a Trust and for so long as any of the
corresponding series of Preferred Securities issued by such Trust shall remain
outstanding, the holders of such Preferred Securities; or

         (8) to evidence and provide for the acceptance of appointment hereunder
by a successor Trustee with respect to the Securities of one or more series and
to add to or change any of the provisions of this Indenture as shall be
necessary to provide for or facilitate the administration of the trusts
hereunder by more than one Trustee, pursuant to the requirements of Section
6.11(b); or

         (9) to comply with the requirements of the Commission in order to
effect or maintain the qualification of this Indenture under the Trust Indenture
Act.

         SECTION 9.2.   Supplemental Indentures with Consent of Holders.

         With the consent of the Holders of not less than a majority in
principal amount of the Outstanding Securities of each series affected by such
supplemental indenture, by Act of said Holders delivered to the Company and the
Trustee, the Company, when authorized by a Board Resolution, and the Trustee may
enter into an indenture or indentures supplemental hereto for the purpose of
adding any provisions to or changing in any manner or eliminating any of the
provisions of this Indenture or of modifying in any manner the rights of the
Holders of Securities of such series under this Indenture; provided, however,
that no such supplemental indenture shall, without the consent of the Holder of
each Outstanding Security affected thereby,

         (1) except to the extent permitted by Section 3.11 or as otherwise
specified as contemplated by Section 2.1 or Section 3.1 with respect to the
deferral of the payment of interest on the Securities of any series, change the
Stated Maturity of the principal of, or any installment of interest (including
any Additional Interest) on, any Security, or reduce the principal amount
thereof or the rate of interest thereon or reduce any premium payable upon the
redemption thereof, or reduce the amount of principal of a Discount Security
that would be due and payable upon a declaration of acceleration of the Maturity
thereof pursuant to Section 5.2, or change the place of payment where, or the
coin or currency in which, any Security or interest thereon is payable, or
impair the right to institute suit for the enforcement of any such payment on or
after the Stated Maturity thereof (or, in the case of redemption, on or after
the Redemption Date), or

         (2) reduce the percentage in principal amount of the Outstanding
Securities of any series, the consent of whose Holders is required for any such
supplemental indenture, or the consent of whose Holders is required for any
waiver (of compliance with certain provisions of this Indenture or certain
defaults hereunder and their consequences) provided for in this Indenture, or

         (3) modify any of the provisions of this Section, Section 5.13 or
Section 10.5, except to increase any such percentage or to provide that certain
other provisions of this Indenture cannot be modified or waived without the
consent of the Holder of each Security affected thereby; or



<PAGE>   64


                                                                              57



         (4) modify the provisions in Article XIII of this Indenture with
respect to the subordination of Outstanding Securities of any series in a manner
adverse to the Holders thereof; provided, further, that, in the case of the
Securities of a series issued to a Trust, so long as any of the corresponding
series of Preferred Securities issued by such Trust remains outstanding, (i) no
such amendment shall be made that adversely affects the holders of such
Preferred Securities in any material respect, and no termination of this
Indenture shall occur, and no waiver of any Event of Default or compliance with
any covenant under this Indenture shall be effective, without the prior consent
of the holders of at least a majority of the aggregate Liquidation Amount (as
defined in the Trust Agreement under which such Trust is organized) of such
Preferred Securities then outstanding unless and until the principal (and
premium, if any) of the Securities of such series and all accrued and, subject
to Section 3.7, unpaid interest (including any Additional Interest) thereon have
been paid in full and (ii) no amendment shall be made to Section 5.8 of this
Indenture that would impair the rights of the holders of Preferred Securities
provided therein without the prior consent of the holders of each Preferred
Security then outstanding unless and until the principal (and premium, if any)
of the Securities of such series and all accrued and (subject to Section 3.7)
unpaid interest (including any Additional Interest) thereon have been paid in
full.

         A supplemental indenture that changes or eliminates any covenant or
other provision of this Indenture that has expressly been included solely for
the benefit of one or more particular series of Securities or Preferred
Securities, or which modifies the rights of the Holders of Securities or holders
of Preferred Securities of such series with respect to such covenant or other
provision, shall be deemed not to affect the rights under this Indenture of the
Holders of Securities or holders of Preferred Securities of any other series.

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

         SECTION 9.3.   Execution of Supplemental Indentures.

         In executing or accepting the additional trusts created by any
supplemental indenture permitted by this Article or the modifications thereby of
the trusts created by this Indenture, the Trustee shall be entitled to receive,
and (subject to Section 6.1) shall be fully protected in relying upon, an
Officers' Certificate and an Opinion of Counsel stating that the execution of
such supplemental indenture is authorized or permitted by this Indenture, and
that all conditions precedent have been complied with. The Trustee may, but
shall not be obligated to, enter into any such supplemental indenture which
affects the Trustee's own rights, duties or immunities under this Indenture or
otherwise.

                                                                              58



         SECTION 9.4.   Effect of Supplemental Indentures.

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

         SECTION 9.5.   Conformity with Trust Indenture Act.

         Every supplemental indenture executed pursuant to this Article shall
conform to the requirements of the Trust Indenture Act as then in effect.

         SECTION 9.6.   Reference in Securities to Supplemental Indentures.

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


                                    ARTICLE X

                                    COVENANTS

         SECTION 10.1.  Payment of Principal, Premium and Interest.

         The Company covenants and agrees for the benefit of each series of
Securities that it will duly and punctually pay the principal of (and premium,
if any) and interest (including Additional Interest) on the Securities of that
series in accordance with the terms of such Securities and this Indenture.

         SECTION 10.2.  Maintenance of Office or Agency.

         The Company will maintain in each Place of Payment for any series of
Securities, an office or agency where Securities of that series may be presented
or surrendered for payment and an office or agency where Securities of that
series may be surrendered for transfer or exchange and where notices and demands
to or upon the Company in respect of the Securities of that series and this
Indenture may be served. The Company initially appoints the Trustee, acting
through its Corporate Trust Office, as its agent for said purposes. The Company
will give prompt written notice to the Trustee of any change in the location of
any such office or agency. If at any time the Company shall fail to maintain
such office or agency or shall fail to furnish the Trustee with the address
thereof, such presentations, surrenders, notices and demands may be made or
served at the Corporate Trust Office of the Trustee, and the Company hereby


<PAGE>   66


                                                                              59



appoints the Trustee as its agent to receive all such presentations, surrenders,
notices and demands.

         The Company may also from time to time designate one or more other
offices or agencies where the Securities may be presented or surrendered for any
or all of such purposes, and may from time to time rescind such designations;
provided, however, that no such designation or rescission shall in any manner
relieve the Company of its obligation to maintain an office or agency in each
Place of Payment for Securities of any series for such purposes. The Company
will give prompt written notice to the Trustee of any such designation and any
change in the location of any such office or agency.

         SECTION 10.3.   Money for Security Payments to be Held in Trust.

         If the Company shall at any time act as its own Paying Agent with
respect to any series of Securities, it will, on or before each due date of the
principal of (and premium, if any) or interest on any of the Securities of such
series, segregate and hold in trust for the benefit of the Persons entitled
thereto a sum sufficient to pay the principal (and premium, if any) or interest
so becoming due until such sums shall be paid to such Persons or otherwise
disposed of as herein provided, and will promptly notify the Trustee of its
failure so to act.

         Whenever the Company shall have one or more Paying Agents, it will,
prior to 10:00 a.m. New York City time on each due date of the principal of or
interest on any Securities, deposit with a Paying Agent a sum sufficient to pay
the principal (and premium, if any) or interest so becoming due, such sum to be
held in trust for the benefit of the Persons entitled to such principal and
premium (if any) or interest, and (unless such Paying Agent is the Trustee) the
Company will promptly notify the Trustee of its failure so to act.

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

         (1) hold all sums held by it for the payment of the principal of (and
premium, if any) or interest (including Additional Interest) on Securities 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;

         (2) give the Trustee notice of any default by the Company (or any other
obligor upon the Securities) in the making of any payment of principal (and
premium, if any) or interest (including Additional Interest);

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

         (4) comply with the provisions of the Trust Indenture Act applicable to
it as a Paying Agent.



<PAGE>   67


                                                                              60



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

         Any money deposited with the Trustee or any Paying Agent, or then held
by the Company, in trust for the payment of the principal of (and premium, if
any) or interest (including Additional Interest) on any Security and remaining
unclaimed for two years after such principal (and premium, if any) or interest
has become due and payable shall (unless otherwise required by mandatory
provision of applicable escheat or abandoned or unclaimed property law) be paid
on Company Request to the Company, or (if then held by the Company) shall
(unless otherwise required by mandatory provision of applicable escheat or
abandoned or unclaimed property law) be discharged from such trust; and the
Holder of such Security shall thereafter, as an unsecured general creditor, look
only to the Company for payment thereof, and all liability of the Trustee or
such Paying Agent with respect to such trust money, and all liability of the
Company as trustee thereof, shall thereupon cease; provided, however, that the
Trustee or such Paying Agent, before being required to make any such repayment,
may at the expense of the Company cause to be published once, in a newspaper
published in the English language, customarily published on each Business Day
and of general circulation in the Borough of Manhattan, The City of New York,
notice that such money remains unclaimed and that, after a date specified
therein, which shall not be less than 30 days from the date of such publication,
any unclaimed balance of such money then remaining will be repaid to the
Company.

         SECTION 10.4.   Statement as to Compliance.

         The Company shall deliver to the Trustee, within 120 days after the end
of each calendar year of the Company ending after the date hereof, an Officers'
Certificate, one of the signatories of which shall be the principal executive,
principal financial or principal accounting officer of the Company, covering the
preceding calendar year, stating whether or not to the best knowledge of the
signers thereof the Company is in default in the performance, observance or
fulfillment of or compliance with any of the terms, provisions, covenants and
conditions of this Indenture, and if the Company shall be in default, specifying
all such defaults and the nature and status thereof of which they may have
knowledge. For the purpose of this Section 10.4, compliance shall be determined
without regard to any grace period or requirement of notice provided pursuant to
the terms of this Indenture.

         SECTION 10.5.   Waiver of Certain Covenants.

         The Company may omit in any particular instance to comply with any
covenant or condition provided pursuant to Section 3.1, 9.1(3) or 9.1(4) with
respect to the Securities of any series, if before or after the time for such
compliance the Holders of at least a majority in principal amount of the
Outstanding Securities of such series shall, by Act of such Holders, either
waive such compliance in such instance or generally waive compliance with such
covenant or condition, but no such waiver shall extend to or affect such
covenant or condition except to


<PAGE>   68


                                                                              61



the extent so expressly waived, and, until such waiver shall become effective,
the obligations of the Company in respect of any such covenant or condition
shall remain in full force and effect.

         SECTION 10.6.   Additional Sums.

         In the case of the Securities of a series initially issued to a Trust,
so long as no Event of Default has occurred and is continuing and except as
otherwise specified as contemplated by Section 2.1 or Section 3.1, if (i) a
Trust is the Holder of all of the Outstanding Securities of such series, and
(ii) a Tax Event has occurred and is continuing in respect of such Securities,
the Company shall pay to such Trust (or its permitted successor under the
related Trust Agreement) for so long as such Trust (or its permitted successor)
is the registered holder of the Outstanding Securities of such series, together
with any payment of principal of (or premium, if any) or interest (including any
Additional Interest) on such Securities, such additional sums as may be
necessary in order that the amount of Distributions (including any Additional
Amounts (as defined in such Trust Agreement)) then payable by such Trust in
respect of the related Preferred Securities and Common Securities in accordance
with the terms thereof shall not be reduced as a result of any Additional Taxes
arising from such Tax Event (the "Additional Sums"). Whenever in this Indenture
or the Securities there is a reference in any context to the payment of
principal of (or premium, if any) or interest (including Additional Interest) on
the Securities, such mention shall be deemed to include mention of the payments
of the Additional Sums provided for in this paragraph to the extent that, in
such context, Additional Sums are, were or would be payable in respect thereof
pursuant to the provisions of this paragraph, and any express mention of the
payment of Additional Sums (if applicable) in any provision hereof shall not be
construed as excluding Additional Sums in those provisions hereof where such
express mention is not made; provided, however, that the deferral of the payment
of interest pursuant to Section 3.11 or the terms of the Securities shall not
defer the payment of any Additional Sums that may be due and payable.

         SECTION 10.7.   Additional Covenants.

         The Company covenants and agrees with each Holder of Securities of each
series that it shall not, and it shall not permit any Subsidiary of the Company
to, (i) declare or pay any dividends or distributions on, or redeem, purchase,
acquire or make a liquidation payment with respect to, any shares of the
Company's capital stock, or (ii) make any payment of principal of or interest or
premium, if any, on or repay, repurchase or redeem any debt securities of the
Company that rank pari passu with or junior in interest to the Securities of
such series or (iii) make any guarantee payments with respect to any guarantee
by the Company of debt securities of any subsidiary of the Company if such
guarantee ranks pari passu with or junior in interest to the Securities (other
than (a) dividends or distributions in the Company's capital stock, (b) any
declaration of a dividend in connection with the implementation of a Rights Plan
or the redemption or repurchase of any rights distributed pursuant to a Rights
Plan, (c) payments under the Guarantee with respect to the Preferred Securities
relating to Securities of such Series, and (d) purchases of Common Stock related
to the issuance of Common Stock or rights or options under any of the Company's
benefit plans for its directors, officers, employees or other persons within the
definition of "employee" for purposes of a registration of shares for an
employee benefit plan of the Company, related to the issuance of Common
Stock or rights

                                                                              62



under a dividend reinvestment and stock purchase plan, or related to the
issuance of Common Stock (or securities convertible or exchangeable for Common
Stock) as consideration in an acquisition transaction) if at such time (x) there
shall have occurred any event of which the Company has actual knowledge that (A)
with the giving of notice or the lapse of time or both, would constitute an
Event of Default with respect to the Securities of such series and (B) in
respect of which the Company shall not have taken reasonable steps to cure, (y)
if the Securities of such series are held by a Trust, the Company shall be in
default with respect to its payment of any obligations under the Guarantee
relating to the Preferred Securities issued by such Trust or (z) the Company
shall have given notice of its election to begin an Extension Period with
respect to the Securities of such series as provided herein and shall not have
rescinded such notice, or such Extension Period, or any extension thereof, shall
be continuing.

         The Company also covenants with each Holder of Securities of a series
issued to a Trust (i) to maintain directly or indirectly 100% ownership of the
Common Securities of such Trust; provided, however, that any permitted successor
of the Company hereunder may succeed to the Company's ownership of such Common
Securities, (ii) not to voluntarily terminate, wind-up or liquidate such Trust,
except (a) in connection with a distribution of the Securities of such series to
the holders of the Trust Securities of such Trust in liquidation of such Trust
or (b) in connection with certain mergers, consolidations or amalgamations
permitted by the related Trust Agreement and (iii) to use its reasonable
efforts, consistent with the terms and provisions of such Trust Agreement, to
cause such Trust to remain classified as a grantor trust and not be
taxable as a corporation for United States federal income tax purposes.

         SECTION 10.8.   Calculation of Original Issue Discount.

         The Company shall file with the Trustee promptly at the end of each
calendar year a written notice specifying the amount of original issue discount
(including daily rates and accrual periods) accrued on Outstanding Securities as
of the end of such year, if any.


                                   ARTICLE XI

                            REDEMPTION OF SECURITIES

         SECTION 11.1.   Applicability of This Article.

         Redemption of Securities of any series (whether by operation of a
sinking fund or otherwise) as permitted or required by any form of Security
issued pursuant to this Indenture shall be made in accordance with such form of
Security and this Article; provided, however, that if any provision of any such
form of Security shall conflict with any provision of this Article, the
provision of such form of Security shall govern. Except as otherwise set forth
in the form of Security for such series, each Security of such series shall be
subject to partial redemption only in the amount of $25 or, in the case of the
Securities of a series issued to a Trust, $25, or integral multiples thereof.

         SECTION 11.2.   Election to Redeem; Notice to Trustee.

                                                                              63



         The election of the Company to redeem any Securities shall be evidenced
by or pursuant to a Board Resolution. In case of any redemption at the election
of the Company of the Securities, the Company shall, not less than 45 nor more
than 60 days prior to the Redemption Date (unless a shorter notice shall be
satisfactory to the Trustee), notify the Trustee of such date and of the
principal amount of Securities of that series to be redeemed. In the case of any
redemption of Securities prior to the expiration of any restriction on such
redemption provided in the terms of such Securities, the Company shall furnish
the Trustee with an Officers' Certificate and an Opinion of Counsel evidencing
compliance with such restriction.

         SECTION 11.3.   Selection of Securities to be Redeemed.

         If less than all the Securities of any series are to be redeemed
(unless all the Securities of a specified tenor are to be redeemed or unless
such redemption affects only a single Security), the particular Securities to be
redeemed shall be selected not more than 60 days prior to the Redemption Date by
the Trustee, from the Outstanding Securities of such series not previously
called for redemption, by lot or such other method as the Trustee shall deem
fair and appropriate and which may provide for the selection for redemption of a
portion of the principal amount of any Security of such series, provided that
the unredeemed portion of the principal amount of any Security shall be in an
authorized denomination (which shall not be less than the minimum authorized
denomination) for such Security. If less than all the Securities of such series
and of a specified tenor are to be redeemed (unless such redemption affects only
a single Security), the particular Securities to be redeemed shall be selected
not more than 60 days prior to the Redemption Date by the Trustee, from the
Outstanding Securities of such series and specified tenor not previously called
for redemption in accordance with the preceding sentence.

        The Trustee shall promptly notify the Company in writing of the
Securities selected for partial redemption and the principal amount thereof to
be redeemed. For all purposes of this Indenture, unless the context otherwise
requires, all provisions relating to the redemption of Securities shall relate,
in the case of any Security redeemed or to be redeemed only in part, to the
portion of the principal amount of such Security which has been or is to be
redeemed. If the Company shall so direct, Securities registered in the name of
the Company, any Affiliate or any Subsidiary thereof shall not be included in
the Securities selected for redemption.

         SECTION 11.4.   Notice of Redemption.

         Notice of redemption shall be given by first-class mail, postage
prepaid, mailed not later than the thirtieth day, and not earlier than the
sixtieth day, prior to the Redemption Date, to each Holder of Securities to be
redeemed, at the address of such Holder as it appears in the Securities
Register.

         With respect to Securities of each series to be redeemed, each notice
of redemption shall identify the Securities to be redeemed (including CUSIP
number, if a CUSIP number has been assigned to such Securities of such Series)
and shall state:

         (a) the Redemption Date;

         (b) the Redemption Price;


<PAGE>   71


                                                                              64




         (c) if less than all Outstanding Securities of such particular series
and having the same terms are to be redeemed, the identification (and, in the
case of partial redemption, the respective principal amounts) of the particular
Securities to be redeemed;

         (d) that on the Redemption Date, the Redemption Price will become due
and payable upon each such Security or portion thereof, and that interest
thereon, if any, shall cease to accrue on and after said date;

         (e) the place or places where such Securities are to be surrendered for
payment of the Redemption Price; and

         (f) that the redemption is for a sinking fund, if such is the case.

         Notice of redemption of Securities to be redeemed at the election of
the Company shall be given by the Company or, at the Company's request, by the
Trustee in the name and at the expense of the Company and shall not be
irrevocable. The notice if mailed in the manner herein provided shall be
conclusively presumed to have been duly given, whether or not the Holder
receives such notice. In any case, a failure to give such notice by mail or any
defect in the notice to the Holder of any Security designated for redemption as
a whole or in part shall not affect the validity of the proceedings for the
redemption of any other Security.

         SECTION 11.5.   Deposit of Redemption Price.

         Prior to 10:00 a.m. New York City time on the Redemption Date specified
in the notice of redemption given as provided in Section 11.4, the Company will
deposit with the Trustee or with one or more Paying Agents (or if the Company is
acting as its own Paying Agent, the Company will segregate and hold in trust as
provided in Section 10.3) an amount of money sufficient to pay the Redemption
Price of, and any accrued interest (including Additional Interest) on, all the
Securities which are to be redeemed on that date.

         SECTION 11.6.   Payment of Securities Called for Redemption.

         If any notice of redemption has been given as provided in Section 11.4,
the Securities or portion of Securities with respect to which such notice has
been given shall become due and payable on the date and at the place or places
stated in such notice at the applicable Redemption Price. On presentation and
surrender of such Securities at a Place of Payment in said notice specified, the
said securities or the specified portions thereof shall be paid and redeemed by
the Company at the applicable Redemption Price, together with accrued interest
(including any Additional Interest) to the Redemption Date; provided, however,
that, unless otherwise specified as contemplated by Section 3.1, installments of
interest whose Stated Maturity is on or prior to the Redemption Date will be
payable to the Holders of such Securities, or one or more Predecessor
Securities, registered as such at the close of business on the relevant Record
Dates according to their terms and the provisions of Section 3.7.

         Upon presentation of any Security redeemed in part only, the Company
shall execute and the Trustee shall authenticate and make available for delivery
to the Holder thereof, at the expense of the Company, a new Security or
Securities of the same series, of authorized


<PAGE>   72


                                                                              65



denominations, in aggregate principal amount equal to the unredeemed portion of
the Security so presented and having the same Original Issue Date, Stated
Maturity and terms. If a Global Security is so surrendered, such new Security
will also be a new Global Security.

         If any Security called for redemption shall not be so paid upon
surrender thereof for redemption, the principal of and premium, if any, on such
Security shall, until paid, bear interest from the Redemption Date at the rate
prescribed therefor in the Security.

         SECTION 11.7.   Right of Redemption of Securities.

         Except as otherwise established pursuant to Section 3.1 for the
Securities of a series, the Company, at its option, may redeem (A) the
Securities of any series, in whole (but not in part), upon the occurrence and
during the continuation of a Tax Event, at any time within 90 days of the
occurrence of such Tax Event, or (B) the Securities of a series initially issued
to a Trust, (i) on or after the date five years after the Original Issue Date of
such Securities, in whole at any time or in part from time to time, or (ii) upon
the occurrence and during the continuation of a Capital Treatment Event, at any
time within 90 days following the occurrence of such Capital Treatment Event in
respect of such Trust, in whole (but not in part), in each case at a Redemption
Price equal to 100% of the principal amount thereof.


                                   ARTICLE XII

                                  SINKING FUNDS

         SECTION 12.1.   Applicability of Article.

         The provisions of this Article shall be applicable to any sinking fund
for the retirement of Securities of any series except as otherwise specified as
contemplated by Section 3.1 for such Securities.

         The minimum amount of any sinking fund payment provided for by the
terms of any Securities of any series is herein referred to as a "mandatory
sinking fund payment", and any sinking fund payment in excess of such minimum
amount which is permitted to be made by the terms of such Securities of any
series is herein referred to as an "optional sinking fund payment". If provided
for by the terms of any Securities of any series, the cash amount of any sinking
fund payment may be subject to reduction as provided in Section 12.2. Each
sinking fund payment shall be applied to the redemption of Securities of any
series as provided for by the terms of such Securities.



<PAGE>   73


                                                                              66



         SECTION 12.2.   Satisfaction of Sinking Fund Payments with Securities.

         In lieu of making all or any part of a mandatory sinking fund payment
with respect to any Securities of a series in cash, the Company may at its
option, at any time no more than 16 months and no less than 30 days prior to the
date on which such sinking fund payment is due, deliver to the Trustee
Securities of such series (together with the unmatured coupons, if any,
appertaining thereto) theretofore purchased or otherwise acquired by the
Company, except Securities of such series that have been redeemed through the
application of mandatory or optional sinking fund payments pursuant to the terms
of the Securities of such series, accompanied by a Company Order instructing the
Trustee to credit such obligations and stating that the Securities of such
series were originally issued by the Company by way of bona fide sale or other
negotiation for value; provided that the Securities to be so credited have not
been previously so credited. The Securities to be so credited shall be received
and credited for such purpose by the Trustee at the redemption price for such
Securities, as specified in the Securities so to be redeemed, for redemption
through operation of the sinking fund and the amount of such sinking fund
payment shall be reduced accordingly.

         SECTION 12.3.   Redemption of Securities for Sinking Fund.

         Not less than 60 days prior to each sinking fund payment date for any
series of Securities, the Company will deliver to the Trustee an Officers'
Certificate specifying the amount of the next ensuing sinking fund payment for
such Securities pursuant to the terms of such Securities, the portion thereof,
if any, which is to be satisfied by payment of cash in the currency in which the
Securities of such series are payable (except as provided pursuant to Section
3.1) and the portion thereof, if any, which is to be satisfied by delivering and
crediting Securities pursuant to Section 12.2 and will also deliver to the
Trustee any Securities to be so delivered. Such Officers' Certificate shall be
irrevocable and upon its delivery the Company shall be obligated to make the
cash payment or payments therein referred to, if any, on or before the
succeeding sinking fund payment date. In the case of the failure of the Company
to deliver such Officers' Certificate (or, as required by this Indenture, the
Securities and coupons, if any, specified in such Officers' Certificate), the
sinking fund payment due on the succeeding sinking fund payment date for such
series shall be paid entirely in cash and shall be sufficient to redeem the
principal amount of the Securities of such series subject to a mandatory sinking
fund payment without the right to deliver or credit securities as provided in
Section 12.2 and without the right to make the optional sinking fund payment
with respect to such series at such time.

         Any sinking fund payment or payments (mandatory or optional) made in
cash plus any unused balance of any preceding sinking fund payments made with
respect to the Securities of any particular series shall be applied by the
Trustee (or by the Company if the Company is acting as its own Paying Agent) on
the sinking fund payment date on which such payment is made (or, if such payment
is made before a sinking fund payment date, on the sinking fund payment date
immediately following the date of such payment) to the redemption of Securities
of such series at the Redemption Price specified in such Securities with respect
to the sinking fund. Any sinking fund moneys not so applied or allocated by the
Trustee (or, if the Company is acting as its own Paying Agent, segregated and
held in trust by the Company as provided in Section 10.3) for such series and
together with such payment (or such amount so segregated) shall be applied in
accordance with the provisions of this Section 12.3. Any and all sinking fund


<PAGE>   74


                                                                              67



moneys with respect to the Securities of any particular series held by the
Trustee (or if the Company is acting as its own Paying Agent, segregated and
held in trust as provided in Section 10.3) on the last sinking fund payment date
with respect to Securities of such series and not held for the payment or
redemption of particular Securities of such series shall be applied by the
Trustee (or by the Company if the Company is acting as its own Paying Agent),
together with other moneys, if necessary, to be deposited (or segregated)
sufficient for the purpose, to the payment of the principal of the Securities of
such series at Maturity. The Trustee shall select the Securities to be redeemed
upon such sinking fund payment date in the manner specified in Section 11.3 and
cause notice of the redemption thereof to be given in the name of and at the
expense of the Company in the manner provided in Section 11.4. Such notice
having been duly given, the redemption of such Securities shall be made upon the
terms and in the manner stated in Section 11.6. On or before each sinking fund
payment date, the Company shall pay to the Trustee (or, if the Company is acting
as its own Paying Agent, the Company shall segregate and hold in trust as
provided in Section 10.3) in cash a sum in the currency in which Securities of
such series are payable (except as provided pursuant to Section 3.1) equal to
the principal and any interest accrued to the Redemption Date for Securities or
portions thereof to be redeemed on such sinking fund payment date pursuant to
this Section 12.3.

         Neither the Trustee nor the Company shall redeem any Securities of a
series with sinking fund moneys or mail any notice of redemption of Securities
of such series by operation of the sinking fund for such series during the
continuance of a default in payment of interest, if any, on any Securities of
such series or of any Event of Default (other than an Event of Default occurring
as a consequence of this paragraph) with respect to the Securities of such
series, except that if the notice of redemption shall have been provided in
accordance with the provisions hereof, the Trustee (or the Company, if the
Company is then acting as its own Paying Agent) shall redeem such Securities if
cash sufficient for that purpose shall be deposited with the Trustee (or
segregated by the Company) in accordance with the terms of this Article XII.
Except as aforesaid, any moneys in the sinking fund for such series at the time
when any such default or Event of Default shall occur and any moneys thereafter
paid into such sinking fund shall, during the continuance of such default or
Event of Default, be held as security for the payment of the Securities and
coupons, if any, of such series; provided, however, that in case such default or
Event of Default shall have been cured or waived herein, such moneys shall
thereafter be applied on the next sinking fund payment date for the Securities
of such series on which such moneys may be applied pursuant to the provisions of
this Section 12.3.


                                  ARTICLE XIII

                           SUBORDINATION OF SECURITIES

         SECTION 13.1.   Securities Subordinate to Senior Indebtedness.

         The Company covenants and agrees, and each Holder of a Security, by its
acceptance thereof, likewise covenants and agrees, that, to the extent and in
the manner hereinafter set forth in this Article, the payment of the principal
of (and premium, if any) and interest (including any


<PAGE>   75


                                                                              68



Additional Interest) on each and all of the Securities are hereby expressly made
subordinate and subject in right of payment to the prior payment in full of all
Senior Indebtedness.

         SECTION 13.2. No Payment When Senior Indebtedness in Default; Payment
Over of Proceeds Upon Dissolution, Etc.

         In the event that the Company shall default in the payment of any
principal of (or premium, if any) or interest on any Senior Indebtedness when
the same becomes due and payable, whether at maturity or at a date fixed for
prepayment or by declaration of acceleration or otherwise, then, upon written
notice of such default to the Company by the holders of Senior Indebtedness or
any trustee therefor, unless and until such default shall have been cured or
waived or shall have ceased to exist, no direct or indirect payment (in cash,
property, securities, by set-off or otherwise) shall be made or agreed to be
made on account of the principal of (or premium, if any) or interest on any of
the Securities, or in respect of any redemption, repayment, retirement, purchase
or other acquisition of any of the Securities.

         In the event of (a) any insolvency, bankruptcy, receivership,
liquidation, reorganization, readjustment, composition or other similar
proceedings relating to the Company, its creditors or its property, (b) any
proceeding for the liquidation, dissolution or other winding up of the Company,
voluntary or involuntary, whether or not involving insolvency or bankruptcy
proceedings, (c) any assignment by the Company for the benefit of creditors or
(d) any other marshalling of the assets of the Company (each such event, if any,
herein sometimes referred to as a "Proceeding"), all Senior Indebtedness
(including any interest thereon accruing after the commencement of any such
proceedings) shall first be paid in full before any payment or distribution,
whether in cash, securities or other property, shall be made to any Holder of
any of the Securities on account thereof. Any payment or distribution, whether
in cash, securities or other property (other than securities of the Company or
any other corporation provided for by a plan of reorganization or readjustment
the payment of which is subordinate, at least to the extent provided in these
subordination provisions with respect to the indebtedness evidenced by the
Securities, to the payment of all Senior Indebtedness at the time outstanding
and to any securities issued in respect thereof under any such plan of
reorganization or readjustment), which would otherwise (but for these
subordination provisions) be payable or deliverable in respect of the Securities
of any series, shall be paid or delivered directly to the holders of Senior
Indebtedness in accordance with the priorities then existing among such holders
until all Senior Indebtedness (including any interest thereon accruing after the
commencement of any Proceeding) shall have been paid in full.

         In the event of any Proceeding, after payment in full of all sums owing
with respect to Senior Indebtedness, the Holders of the Securities, together
with the holders of any obligations of the Company ranking on a parity with the
Securities (which for this purpose only shall include the Allocable Amounts of
Senior Subordinated Debt), shall be entitled to be paid from the remaining
assets of the Company the amounts at the time due and owing on account of unpaid
principal of (and premium, if any) and interest on the Securities and such other
obligations before any payment or other distribution, whether in cash, property
or otherwise, shall be made on account of any capital stock or any obligations
of the Company ranking junior to the Securities and such other obligations. In
the event that, notwithstanding the foregoing, any payment or distribution of
any character or any security, whether in cash, securities or other


<PAGE>   76


                                                                              69



property (other than securities of the Company or any other corporation provided
for by a plan of reorganization or readjustment the payment of which is
subordinate, at least to the extent provided in these subordination provisions
with respect to the indebtedness evidenced by the Securities, to the payment of
all Senior Indebtedness at the time outstanding and to any securities issued in
respect thereof under any such plan of reorganization or readjustment), shall be
received by the Trustee or any Holder in contravention of any of the terms
hereof and before all Senior Indebtedness shall have been paid in full, such
payment or distribution or security shall be received in trust for the benefit
of, and shall be paid over or delivered and transferred to, the holders of the
Senior Indebtedness at the time outstanding in accordance with the priorities
then existing among such holders for application to the payment of all Senior
Indebtedness remaining unpaid, to the extent necessary to pay all such Senior
Indebtedness in full. In the event of the failure of the Trustee or any Holder
to endorse or assign any such payment, distribution or security, each holder of
Senior Indebtedness is hereby irrevocably authorized to endorse or assign the
same.

         The Trustee and Holders will take such action (including, without
limitation, the delivery of this Indenture to an agent for the holders of Senior
Indebtedness or consent to the filing of a financing statement with respect
hereto) as may, in the opinion of counsel designated by the holders of a
majority in principal amount of the Senior Indebtedness at the time outstanding,
be necessary or appropriate to assure the effectiveness of the subordination
effected by these provisions.

         The provisions of this Section 13.2 shall not impair any rights,
interests, remedies or powers of any secured creditor of the Company in respect
of any security interest the creation of which is not prohibited by the
provisions of this Indenture.

         The securing of any obligations of the Company, otherwise raking on a
parity with the Securities or ranking junior to the Securities, shall not be
deemed to prevent such obligations from constituting, respectively, obligations
ranking on a parity with the Securities or ranking junior to the Securities.

         SECTION 13.3. Payment Permitted If No Default.

         Nothing contained in this Article or elsewhere in this Indenture, or in
any of the Securities, shall prevent (a) the Company at any time, except during
the conditions described in the first paragraph of Section 13.2 or the pendency
of any Proceeding referred to in Section 13.2, from making payments at any time
of principal of (and premium, if any) or interest (including Additional
Interest) on the Securities, or (b) the application by the Trustee of any moneys
deposited with it hereunder to the payment of or on account of the principal of
(and premium, if any) or interest (including any Additional Interest) on the
Securities or the retention of such payment by the Holders, if, at the time of
such application by the Trustee, it did not have knowledge that such payment
would have been prohibited by the provisions of this Article.

         SECTION 13.4. Subrogation to Rights of Holders of Senior Indebtedness.

         Subject to the payment in full of all amounts due or to become due on
all Senior Indebtedness, or the provision for such payment in cash or cash
equivalents or otherwise in a


<PAGE>   77


                                                                              70



manner satisfactory to the holders of Senior Indebtedness, the Holders of the
Securities shall be subrogated to the extent of the payments or distributions
made to the holders of such Senior Indebtedness pursuant to the provisions of
this Article (equally and ratably with the holders of all indebtedness of the
Company which by its express terms is subordinated to Senior Indebtedness of the
Company to substantially the same extent as the Securities are subordinated to
the Senior Indebtedness and is entitled to like rights of subrogation by reason
of any payments or distributions made to holders of such Senior Indebtedness) to
the rights of the holders of such Senior Indebtedness to receive payments and
distributions of cash, property and securities applicable to the Senior
Indebtedness until the principal of (and premium, if any) and interest on the
Securities shall be paid in full. For purposes of such subrogation, no payments
or distributions to the holders of the Senior Indebtedness of any cash, property
or securities to which the Holders of the Securities or the Trustee would be
entitled except for the provisions of this Article, and no payments over
pursuant to the provisions of this Article to the holders of Senior Indebtedness
by Holders of the Securities or the Trustee, shall, as among the Company, its
creditors other than holders of Senior Indebtedness, and the Holders of the
Securities, be deemed to be a payment or distribution by the Company to or on
account of the Senior Indebtedness.

         SECTION 13.5. Provisions Solely to Define Relative Rights.

         The provisions of this Article are and are intended solely for the
purpose of defining the relative rights of the Holders of the Securities on the
one hand and the holders of Senior Indebtedness on the other hand. Nothing
contained in this Article or elsewhere in this Indenture or in the Securities is
intended to or shall (a) impair, as between the Company and the Holders of the
Securities, the obligations of the Company, which are absolute and
unconditional, to pay to the Holders of the Securities the principal of (and
premium, if any) and interest (including any Additional Interest) on the
Securities as and when the same shall become due and payable in accordance with
their terms; or (b) affect the relative rights against the Company of the
Holders of the Securities and creditors of the Company other than their rights
in relation to the holders of Senior Indebtedness; or (c) prevent the Trustee or
the Holder of any Security from exercising all remedies otherwise permitted by
applicable law upon default under this Indenture including, without limitation,
filing and voting claims in any Proceeding, subject to the rights, if any, under
this Article of the holders of Senior Indebtedness to receive cash, property and
securities otherwise payable or deliverable to the Trustee or such Holder.

         SECTION 13.6. Trustee to Effectuate Subordination.

         Each Holder of a Security by his or her acceptance thereof authorizes
and directs the Trustee on his or her behalf to take such action as may be
necessary or appropriate to acknowledge or effectuate the subordination provided
in this Article and appoints the Trustee his or her attorney-in-fact for any and
all such purposes.

         SECTION 13.7. No Waiver of Subordination Provisions.

         No right of any present or future holder of any Senior Indebtedness to
enforce subordination as herein provided shall at any time in any way be
prejudiced or impaired by any act or failure to act on the part of the Company
or by any act or failure to act, in good faith,


<PAGE>   78


                                                                              71



by any such holder, or by any noncompliance by the Company with the terms,
provisions and covenants of this Indenture, regardless of any knowledge thereof
that any such holder may have or be otherwise charged with.

         Without in any way limiting the generality of the immediately preceding
paragraph, the holders of Senior Indebtedness may, at any time and from to time,
without the consent of or notice to the Trustee or the Holders of the
Securities, without incurring responsibility to the Holders of the Securities
and without impairing or releasing the subordination provided in this Article or
the obligations hereunder of the Holders of the Securities to the holders of
Senior Indebtedness, do any one or more of the following: (i) change the manner,
place or terms of payment or extend the time of payment of, or renew or alter,
Senior Indebtedness, or otherwise amend or supplement in any manner Senior
Indebtedness or any instrument evidencing the same or any agreement under which
Senior Indebtedness is outstanding; (ii) sell, exchange, release or otherwise
deal with any property pledged, mortgaged or otherwise securing Senior
Indebtedness; (iii) release any Person liable in any manner for the collection
of Senior Indebtedness; and (iv) exercise or refrain from exercising any rights
against the Company and any other Person.

         SECTION 13.8. Notice to Trustee.

         The Company shall give prompt written notice to the Trustee of any fact
known to the Company which would prohibit the making of any payment to or by the
Trustee in respect of the Securities. Notwithstanding the provisions of this
Article or any other provision of this Indenture, the Trustee shall not be
charged with knowledge of the existence of any facts which would prohibit the
making of any payment to or by the Trustee in respect of the Securities, unless
and until the Trustee shall have received written notice thereof from the
Company or a holder of Senior Indebtedness or from any trustee, agent or
representative therefor; provided, however, that if the Trustee shall not have
received the notice provided for in this Section at least two Business Days
prior to the date upon which by the terms hereof any monies may become payable
for any purpose (including, without limitation, the payment of the principal of
(and premium, if any) or interest (including any Additional Interest) on any
Security), then, anything herein contained to the contrary notwithstanding, the
Trustee shall have full power and authority to receive such monies and to apply
the same to the purpose for which they were received and shall not be affected
by any notice to the contrary which may be received by it within two Business
Days prior to such date.

         Subject to the provisions of Section 6.1, the Trustee shall be entitled
to rely on the delivery to it of a written notice by a Person representing
himself to be a holder of Senior Indebtedness (or a trustee or attorney-in-fact
therefor) to establish that such notice has been given by a holder of Senior
Indebtedness (or a trustee or attorney-in-fact therefor). In the event that the
Trustee determines in good faith that further evidence is required with respect
to the right of any Person as a holder of Senior Indebtedness to participate in

is not furnished, the Trustee may defer any payment to such Person pending
judicial determination as to the right of such Person to receive such payment.

         SECTION 13.9. Reliance on Judicial Order or Certificate of Liquidating
Agent.

         Upon any payment or distribution of assets of the Company referred to
in this Article, the Trustee, subject to the provisions of Section 6.1, and the
Holders of the Securities shall be entitled to rely upon any order or decree
entered by any court of competent jurisdiction in which such Proceeding is
pending, or a certificate of the trustee in bankruptcy, receiver, liquidating
trustee, custodian, assignee for the benefit of creditors, agent or other Person
making such payment or distribution, delivered to the Trustee or to the Holders
of Securities, for the purpose of ascertaining the Persons entitled to
participate in such payment or distribution, the holders of the Senior
Indebtedness and other indebtedness of the Company, the amount thereof or
payable thereon, the amount or amounts paid or distributed thereon and all other
facts pertinent thereto or to this Article.

         SECTION 13.10. Trustee Not Fiduciary for Holders of Senior 
Indebtedness.

         The Trustee, in its capacity as trustee under this Indenture, shall not
be deemed to owe any fiduciary duty to the holders of Senior Indebtedness and
shall not be liable to any such holders if it shall in good faith mistakenly pay
over or distribute to Holders of Securities or to the Company or to any other
Person cash, property or securities to which any holders of Senior Indebtedness
shall be entitled by virtue of this Article or otherwise. With respect to the
Holders of Senior Indebtedness, the Trustee undertakes to perform or to observe

Article and no implied covenants or obligations with respect to Holders of
Senior Indebtedness shall be read into this Indenture against the Trustee.


         SECTION 13.11. Rights of Trustee as Holder of Senior Indebtedness;
Preservation of Trustee's Rights.

         The Trustee in its individual capacity shall be entitled to all the
rights set forth in this Article with respect to any Senior Indebtedness which
may at any time be held by it, to the same extent as any other holder of Senior
Indebtedness, and nothing in this Indenture shall deprive the Trustee of any of
its rights as such holder.

         Nothing in this Article shall apply to claims of, or payments to, the
Trust under or pursuant to Section 6.7.

         SECTION 13.12. Article Applicable to Paying Agents.

         In case at any time any Paying Agent other than the Trustee shall have
been appointed by the Company and be then acting hereunder, the term "Trustee"
as used in this Article shall in such case (unless the context otherwise
requires) be construed as extending to and including such Paying Agent within
its meaning as fully for all intents and purposes as if such Paying Agent were
named in this Article in addition to or in place of the Trustee.

                      FIRST TENNESSEE NATIONAL CORPORATION
       8.07% JUNIOR SUBORDINATED DEFERRABLE INTEREST DEBENTURES, SERIES A

No. 1                                                               $103,093,000

         FIRST TENNESSEE NATIONAL CORPORATION, a corporation organized and
existing under the laws of the state of Tennessee (hereinafter called the
"Company", which term includes any successor corporation under the Indenture
hereinafter referred to), for value received, hereby promises to pay to First
Tennessee Capital I, or registered assigns, the principal sum of $103,093,000
Dollars on January 6, 2027; provided that the Company may shorten this Stated
Maturity of the principal of this Security to a date not earlier than January 6,
2017, in the circumstances described on the reverse hereof. The Company further
promises to pay interest on said principal sum from January 6, 1997 or from the
most recent interest payment date (each such date, an "Interest Payment Date")
on which interest has been paid or duly provided for, semi-annually (subject to
deferral as set forth herein) in arrears on January 6 and July 6 of each year,
commencing July 6, 1997, at the rate of 8.07% per annum, until the principal
hereof shall have become due and payable, plus Additional Interest, if any,
until the principal hereof is paid or duly provided for or made available for
payment and on any overdue principal and (without duplication and to the extent
that payment of such interest is enforceable under applicable law) on any
overdue installment of interest at the rate of 8.07% per annum, compounded
semi-annually. The amount of interest payable for any period shall be computed
on the basis of twelve 30-day months and a 360-day year. The amount of interest
payable for any partial period shall be computed on the basis of the number of
days elapsed in a 360-day year of twelve 30-day months. In the event that any
date on which interest is payable on this Security is not a Business Day, then a
payment of the interest payable on such date will be made on the next succeeding
day which is a Business Day (and without any interest or other payment in
respect of any such delay), except that, if such Business Day is in the next
succeeding calendar year, such payment shall be made on the immediately
preceding Business Day, in each case with the same force and effect as if made
on the date the payment was originally payable. A "Business Day" shall mean any
day other than (i) a Saturday or Sunday, (ii) a day on which banking
institutions in The City of New York are authorized or required by law or
executive order to remain closed or (iii) a day on which the Corporate Trust
Office of the Trustee or the principal office of the Property Trustee under the
Trust Agreement hereinafter referred to for First Tennessee Capital I, is closed
for business. The interest installment so payable, and punctually paid or duly
provided for, on any Interest Payment Date will, as provided in the Indenture,
be paid to the Person in whose name this Security (or one or more Predecessor
Securities) is registered at the close of business on the Regular Record Date
for such interest installment, which shall be, for so long as this Security is
held by a Trust or in Global form, the Business Day next preceding the Interest
Payment Date and, if this Security is not held by a Trust or in Global form,
fifteen days prior to the Interest Payment Date. Any such interest installment
not so punctually paid or duly provided for shall forthwith cease to be payable
to the Holder on such Regular Record Date and may either be paid to the Person
in whose name this Security (or one or more Predecessor Securities) is
registered at the close of business on a Special Record Date for the payment of
such Defaulted Interest to be fixed by the Trustee, notice whereof shall be
given to Holders of Securities of this series not less than 10 days prior to
such Special Record Date, or be paid at any time in any other lawful
<PAGE>   2
manner not inconsistent with the requirements of any securities exchange or
automated quotation system on which the Securities of this series may be listed
or traded, and upon such notice as may be required by such exchange or
self-regulatory organization, all as more fully provided in said Indenture.

         So long as no Event of Default has occurred and is continuing, the
Company shall have the right at any time during the term of this Security to
defer payment of interest on this Security, at any time or from time to time,
for up to 10 consecutive semi-annual interest payment periods with respect to
each deferral period (each an "Extension Period"), during which Extension
Periods the Company shall have the right to make partial payments of interest on
any Interest Payment Date, and at the end of which the Company shall pay all
interest then accrued and unpaid (together with Additional Interest thereon to
the extent permitted by applicable law); provided, however, that no Extension
Period shall extend beyond the Stated Maturity of the principal of this
Security; provided, further, that during any such Extension Period, the Company
shall not, and shall not permit any Subsidiary of the Company to, (i) declare or
pay any dividends or distributions on or redeem, purchase, acquire or make a
liquidation payment with respect to, any of the Company's capital stock or (ii)
make any payment of principal of or interest or premium, if any, on or repay,
repurchase or redeem any debt security of the Company that ranks pari passu with
or junior in interest to this Security or (iii) make any guarantee payments with
respect to any guarantee by the Company of the debt securities of any Subsidiary
of the Company if such guarantee ranks pari passu with or junior in interest to
this Security (other than (a) dividends or distributions in the Company's
capital stock, (b) any declaration of a dividend in connection with the
implementation of a Rights Plan or the redemption or repurchase of any rights
distributed pursuant to a Rights Plan, (c) payments under the Guarantee with
respect to this Security, and (d) purchases of Common Stock related to the
issuance of Common Stock or rights or options under any of the Company's benefit
plans for its directors, officers, employees or other persons within the
definition of "employee" for purposes of a registration of shares for an
employee benefit plan of the Company, related to the issuance of Common Stock or
rights under a dividend reinvestment and stock purchase plan, or related to the
issuance of Common Stock (or securities convertible or exchangeable for Common
Stock) as consideration in an acquisition transaction that was entered into
prior to the commencement of such Extension Period). Prior to the termination of
any such Extension Period, the Company may further defer the payment of
interest, provided that no Extension Period shall exceed 10 consecutive
semi-annual periods or extend beyond the Stated Maturity of the principal of
this Security. Upon the termination of any such Extension Period and upon the
payment of all accrued and unpaid interest and any Additional Interest then due,
the Company may elect to begin a new Extension Period, subject to the above
requirements. No interest shall be due and payable during an Extension Period
except at the end thereof. The Company shall give the Holder of this Security
and the Trustee notice of its election to begin any Extension Period at least
one Business Day prior to the next succeeding Interest Payment Date on which
interest on this Security would be payable but for such deferral or, with
respect to the Securities issued to a Trust, so long as such Securities are held
by such Trust, prior to the earlier of (i) the next succeeding date on which
Distributions on the Preferred Securities would be payable but for such deferral
or (ii) the date the Administrative Trustees are required to give

                                       -2-
<PAGE>   3
notice to any securities exchange or other applicable self-regulatory
organization or to holders of such Preferred Securities of the record date or
the date such Distributions are payable, but in any event not less than one
Business Day prior to such record date.

         Payment of principal of (and premium, if any) and interest on this
Security will be made at the office or agency of the Company maintained for that
purpose in the United States, in such coin or currency of the United States of
America as at the time of payment is legal tender for payment of public and
private debts; provided, however, that at the option of the Company payment of
interest may be made (i) by check mailed to the address of the Person entitled
thereto as such address shall appear in the Securities Register or (ii) by wire
transfer or direct deposit in immediately available funds at such place and to
such account as may be designated in writing by the relevant Regular Record Date
by the Person entitled thereto as specified in the Securities Register.

         The indebtedness evidenced by this Security is, to the extent provided
in the Indenture, subordinate and subject in right of payment to the prior
payment in full of all Senior Indebtedness, and this Security is issued subject
to the provisions of the Indenture with respect thereto. Each Holder of this
Security, by accepting the same, (a) agrees to and shall be bound by such
provisions, (b) authorizes and directs the Trustee on his behalf to take such
actions as may be necessary or appropriate to effectuate the subordination so
provided and (c) appoints the Trustee his attorney-in-fact for any and all such
purposes. Each Holder hereof, by its acceptance hereof, waives all notice of the
acceptance of the subordination provisions contained herein and in the Indenture
by each holder of Senior Indebtedness, whether now outstanding or hereafter
incurred, and waives reliance by each such holder upon said provisions.

         Reference is hereby made to the further provisions of this Security set
forth on the reverse hereof, which further provisions shall for all purposes
have the same effect as if set forth at this place.

         Unless the certificate of authentication hereon has been executed by
the Trustee referred to on the reverse hereof by manual signature, this Security
shall not be entitled to any benefit under the Indenture or be valid or
obligatory for any purpose.

         This Security is one of a duly authorized issue of securities of the
Company (herein called the "Securities"), issued and to be issued in one or more
series under a Junior Subordinated Indenture, dated as of December 30, 1996
(herein called the "Indenture"), between the Company and The Bank of New York,
as Trustee (herein called the "Trustee", which term includes any successor
trustee under the Indenture), to which Indenture and all indentures supplemental
thereto reference is hereby made for a statement of the respective rights,
limitations of rights, duties and immunities thereunder of the Trustee, the
Company and the Holders of the Securities, and of the terms upon which the
Securities are, and are to be, authenticated and delivered. This Security is one
of the series designated on the face hereof.

         All terms used in this Security that are defined in the Indenture or in
the Amended and Restated Trust Agreement, dated as of December 30, 1996, as
amended (the "Trust Agreement"), for First Tennessee Capital I, among First
Tennessee National Corporation, as Depositor, and the Trustees named therein,
shall have the meanings assigned to them in the Indenture or the Trust
Agreement, as the case may be.

         The Company may at any time, at its option, on or after January 6,
2007, and subject to the terms and conditions of Article XI of the Indenture,
redeem this Security in whole at any time or in part from time to time, at a

         In the event of redemption of this Security in part only, a new
Security or Securities of this series for the unredeemed portion hereof will be
issued in the name of the Holder hereof upon the cancellation hereof.

         If at any time a Tax Event or a Capital Treatment Event occurs and (i)
in the opinion of counsel to the Company experienced in such matters, there
would in all cases, after effecting the termination of any Trust which holds
this Security and the distribution of this Security to the holders of the Trust
Securities of such Trust in exchange therefor, be more than an insubstantial
risk that an Adverse Tax Consequence (as defined below) would continue to exist,
(ii) in the reasonable determination of the Company, there would in all cases,
after effecting the termination of any Trust which holds this Security and the
distribution of this Security to the holders of the Trust Securities of such
Trust in exchange therefor, be more than an insubstantial risk that the
Corporation would not be entitled to treat an amount equal to the Liquidation
Amount of such Trust Securities as "Tier 1 Capital" (or the then equivalent
thereof) for purposes of the capital adequacy guidelines of the Federal Reserve,
as then in effect and applicable to the Company, or (iii) this Security is not
held by a Trust, then the Company shall have the right (a) to shorten the Stated
Maturity of this Security to the minimum extent required, but in any event to a
date not earlier than January 6, 2017 (the action referred to in this clause (a)
being referred to herein as a "Maturity Advancement"), such that, in the opinion
of counsel to the Company experienced in such matters, after advancing the
Stated Maturity, interest paid hereon will be deductible for United States
federal income tax purposes, or (b) if either (x) in the opinion of counsel to
the Company experienced in such matters, there would in all cases, after
effecting a Maturity Advancement, be more than an insubstantial risk that an
Adverse Tax Consequence would continue to exist or (y) in the reasonable
determination of the Company, there would in all cases, after effecting a
Maturity Advancement, be more than an insubstantial risk that the Company would
not be entitled to treat an amount equal to the Liquidation Amount of the Trust
Securities of a Trust holding this Security, if any, as "Tier 1 Capital" (or the
then equivalent thereof) for purposes of the capital adequacy guidelines of the
Federal Reserve, as then in effect and applicable to the Company, to redeem this
Security, in whole but not in part, at any time within 90 days following the
occurrence of the Tax Event or Capital Treatment Event, at a Redemption Price
equal to 100% of the principal amount hereof plus accrued and unpaid interest
hereon to the Redemption Date. "Adverse Tax Consequence" means any of the
following circumstances: (i) a Trust which holds this Security is, or will be,
within 90 days of the Opinion of Counsel giving rise to a Tax Event, subject to
United States federal income tax with respect to income received or accrued on
this Security, (ii) interest payable by the Company on this Security is not, or
within 90 days of the date of such Opinion of Counsel will not be, deductible by
the Company, in whole or in part, for United States federal income tax purposes
or (iii) a Trust which holds this Security is, or will be within 90 days of the
date of such Opinion of Counsel, subject to more than a de minimis amount of
other taxes, duties or other governmental charges.

indentures for the purpose of modifying in any manner the rights and obligations
of the Company and of the Holders of the Securities, with the consent of the
Holders of not less than a majority in principal amount of the Outstanding
Securities of all series to be affected by such supplemental indenture. The
Indenture also contains provisions permitting Holders of specified percentages
in principal amount of the Securities of all series at the time Outstanding, on
behalf of the Holders of all Securities of such series, to waive compliance by
the Company with certain provisions of the Indenture and certain past defaults
under the Indenture and their consequences. Any such consent or waiver by the

the Holders of not less than 25% in principal amount of the Outstanding
Securities of this series may declare the principal amount of all the Securities
of this series to be due and payable immediately, by a notice in writing to the
Company (and to the Trustee if given by Holders), provided that, in the case of
the Securities of this series issued to a Trust, if upon an Event of Default,
the Trustee or the Holders of not less than 25% in principal amount of the
Outstanding Securities of this series fails to declare the principal of all the
Securities of this series to be immediately due and payable, the holders of at
least 25% in aggregate Liquidation Amount of the Preferred Securities then
outstanding shall have such right by a notice in writing to the Company and the
Trustee; and upon any such declaration the principal amount of and the accrued
interest (including any Additional Interest) on all the Securities of this
series shall become immediately due and payable, provided that the payment of
principal and interest (including any Additional Interest) on such Securities

or of the Indenture shall alter or impair the obligation of the Company, which

interest on this Security at the times, place and rate, and in the coin or
currency, herein prescribed.

         Commission and the execution on behalf of the Trust of a registration
         statement on the appropriate form in relation to the Capital
         Securities, including any amendments thereto;

                       (ii) the determination of the states in which to take
         appropriate action to qualify or register for sale all or part of the
         Capital Securities and the determination of any and all such acts,
         other than actions which must be taken by or on behalf of the Trust,
         and the advice to the Trustees of actions they must take on behalf of
         the Trust, and the preparation for execution and filing, and the
         execution on behalf of the Trust of any documents to be executed and
         filed by the Trust or on behalf of the Trust, as the Depositor deems

         upon notice of issuance of any Capital Securities and filing with such
         exchange or self-regulatory organization such notifications and
         documents as may be necessary from time to time to maintain such
         listing;

                       (iv) the negotiation of the terms of, and the execution

                       (v) the taking of any other actions necessary or
         desirable to carry out any of the foregoing activities.

         (d) Notwithstanding anything herein to the contrary, the Administrative

operate the Trust so that the Trust will not be deemed to be an "investment
company" required to be registered under the 1940 Act, or be taxable as a
corporation or fail to be classified as a grantor trust for United States
federal income tax purposes and so that the Debentures will be treated as
indebtedness of the Depositor for United States federal income tax purposes. In
this connection, the Depositor and the Administrative Trustees are authorized to
take any action, not inconsistent with applicable law, the Certificate of Trust
or this Trust Agreement, that each of the Depositor and any Administrative

                                 PAYMENT ACCOUNT

         SECTION 3.1  Payment Account.

         (a) On or prior to the Closing Date, the Property Trustee shall
establish the Payment Account. The Property Trustee and any agent of the
Property Trustee shall have exclusive control and sole right of withdrawal with

withdrawals from the Payment Account in accordance with this Trust Agreement.
All monies and other property deposited or held from time to time in the Payment
Account shall be held by the Property Trustee in the Payment Account for the
exclusive benefit of the Securityholders and for distribution as herein
provided, including (and subject to) any priority of payments provided for
herein.

         (b) The Property Trustee shall deposit in the Payment Account, promptly
upon receipt, all payments of principal of or interest or premium on, and any
other payments or proceeds with respect to, the Debentures. Amounts held in the

                            DISTRIBUTIONS; REDEMPTION

         SECTION 4.1  Distributions.

         (a) The Trust Securities represent undivided beneficial ownership
interests in the Trust Property, and Distributions (including of Additional
Amounts) will be made on the Trust Securities at the rate and on the dates that
payments of interest (including of Additional Interest, as defined in the
Indenture) are made on the Debentures. Accordingly:

                         (i) Distributions on the Trust Securities shall be
         cumulative, and will accumulate whether or not there are funds of the
         Trust available for the payment of Distributions. Distributions shall
         accrue from January 6, 1997, and, except in the event (and to the
         extent) that the Depositor exercises its right to defer the payment of
         interest on the Debentures pursuant to the Indenture, shall be payable
         semi-annually in 

<PAGE>   24
                                                                              17


         arrears on January 6 and July 6, commencing on July 6, 1997. If any
         date on which a Distribution is otherwise payable on the Trust
         Securities is not a Business Day, then the payment of such Distribution
         shall be made on the next succeeding day that is a Business Day (and
         without any interest or other payment in respect of any such delay)
         except that, if such Business Day is in the next succeeding calendar
         year, payment of such Distribution shall be made on the immediately
         preceding Business Day, in each case with the same force and effect as
         if made on such date (each date on which Distributions are payable in
         accordance with this Section 4.1(a), a "Distribution Date").


                        (ii) Assuming payments of interest on the Debentures are
         made when due (and before giving effect to Additional Amounts, if
         applicable), Distributions on the Trust Securities shall be payable at
         a rate of 8.07% per annum of the Liquidation Amount of the Trust
         Securities. The amount of Distributions payable for any Distribution
         period shall be computed on the basis of a 360-day year of twelve
         30-day months. The amount of Distributions for any partial Distribution
         period shall be computed on the basis of the number of days elapsed in
         a 360-day year of twelve 30-day months. The amount of Distributions
         payable for any period shall include the Additional Amounts, if any.

                       (iii) Distributions on the Trust Securities shall be made
         by the Property Trustee from the Payment Account and shall be payable
         on each Distribution Date only to the extent that the Trust has funds
         then on hand and available in the Payment Account for the payment of
         such Distributions.

         (b) Distributions on the Trust Securities with respect to a
Distribution Date shall be payable to the Holders thereof as they appear on the
Securities Register for the Trust Securities on the relevant record date, which
shall be one Business Day prior to such Distribution Date; provided, however,
that in the event that the Capital Securities do not remain in book-entry-only
form, the relevant record date shall be 15 days prior to the relevant
Distribution Date (whether or not such record date is a Business Day).

         SECTION 4.2  Redemption.

         (a) On each Debenture Redemption Date and the Debenture Maturity Date,
the Trust shall redeem a Like Amount of Trust Securities at the Redemption
Price.

         (b) Notice of redemption shall be given by the Property Trustee by
first-class mail, postage prepaid, mailed not less than 30 nor more than 60 days
prior to the Redemption Date to each Holder of Trust Securities to be redeemed,
at such Holder's address appearing in the Security Register. All notices of
redemption shall state:

                         (i)   the Redemption Date;
<PAGE>   25
                                                                              18



                        (ii)   the Redemption Price;

                       (iii)   the CUSIP number;

                        (iv) if less than all the Outstanding Trust Securities
         are to be redeemed, the identification and the total Liquidation Amount
         of the particular Trust Securities to be redeemed;

                         (v) that on the Redemption Date the Redemption Price
         will become due and payable upon each such Trust Security to be
         redeemed and that Distributions thereon will cease to accrue on and
         after said date; and

                        (vi) if the Capital Securities are no longer in
         book-entry-only form, the place and address where the Holders shall
         surrender their Capital Securities Certificates.

         (c) The Trust Securities redeemed on each Redemption Date shall be
redeemed at the Redemption Price with the proceeds from the contemporaneous
redemption or payment at stated maturity of Debentures. Redemptions of the Trust
Securities shall be made and the Redemption Price shall be payable on each
Redemption Date only to the extent that the Trust has funds then on hand and
available in the Payment Account for the payment of such Redemption Price.

         (d) If the Property Trustee gives a notice of redemption in respect of
any Capital Securities, then, by 12:00 noon, New York City time, on the
Redemption Date, subject to Section 4.2(c), the Property Trustee will, so long
as the Capital Securities are in book-entry-only form, irrevocably deposit with
the Clearing Agency for the Capital Securities funds sufficient to pay the
applicable Redemption Price and will give such Clearing Agency irrevocable
instructions and authority to pay the Redemption Price to the Holders thereof.
If the Capital Securities are no longer in book-entry-only form, the Property
Trustee, subject to Section 4.2(c), will irrevocably deposit with the Paying
Agent funds sufficient to pay the applicable Redemption Price and will give the
Paying Agent irrevocable instructions and authority to pay the Redemption Price
to the Holders thereof upon surrender of their Capital Securities Certificates.
Notwithstanding the foregoing, Distributions payable on or prior to the
Redemption Date for any Trust Securities called for redemption shall be payable
to the Holders of such Trust Securities as they appear on the Securities
Register for the Trust Securities on the relevant record dates for the related
Distribution Dates. If notice of redemption shall have been given and funds
deposited as required, then upon the date of such deposit, all rights of
Securityholders holding Trust Securities so called for redemption will cease,
except the right of such Securityholders to receive the Redemption Price and any
Distribution payable on or prior to the Redemption Date, but without interest
thereon, and such Trust Securities will cease to be outstanding. In the event
that any date on which any Redemption Price is payable is not a Business Day,
then payment of the Redemption Price payable on such date will be made on the
next succeeding day that is a Business Day (and 

<PAGE>   26
                                                                              19



without any interest or other payment in respect of any such delay), except
that, if such Business Day falls in the next calendar year, such payment will be
made on the immediately preceding Business Day, in each case, with the same
force and effect as if made on such date. In the event that payment of the
Redemption Price in respect of any Trust Securities called for redemption is
improperly withheld or refused and not paid either by the Trust or by the
Depositor pursuant to the Guarantee, Distributions on such Trust Securities will
continue to accrue, at the then applicable rate, from the Redemption Date
originally established by the Trust for such Trust Securities to the date such
Redemption Price is actually paid, in which case the actual payment date will be
the date fixed for redemption for purposes of calculating the Redemption Price.

         (e) Payment of the Redemption Price on the Trust Securities shall be
made to the recordholders thereof as they appear on the Securities Register for
the Trust Securities on the relevant record date, which shall be one Business
Day prior to the relevant Redemption Date; provided, however, that in the event
that the Capital Securities do not remain in book-entry-only form, the relevant
record date shall be the date fifteen days prior to the relevant Redemption
Date.

         (f) Subject to Section 4.3(a), if less than all the Outstanding Trust
Securities are to be redeemed on a Redemption Date, then the aggregate
Liquidation Amount of Trust Securities to be redeemed shall be allocated on a
pro rata basis (based on Liquidation Amounts) among the Common Securities and
the Capital Securities. The particular Capital Securities to be redeemed shall
be selected on a pro rata basis (based upon Liquidation Amounts) not more than
60 days prior to the Redemption Date by the Property Trustee from the
Outstanding Capital Securities not previously called for redemption, by such
method as the Property Trustee shall deem fair and appropriate and which may
provide for the selection for redemption of portions (equal to $1,000 or an
integral multiple of $1,000 in excess thereof) of the Liquidation Amount of
Capital Securities of a denomination larger than $1,000. The Property Trustee
shall promptly notify the Security Registrar in writing of the Capital
Securities selected for redemption and, in the case of any Capital Securities
selected for partial redemption, the Liquidation Amount thereof to be redeemed.
For all purposes of this Trust Agreement, unless the context otherwise requires,
all provisions relating to the redemption of Capital Securities shall relate, in
the case of any Capital Securities redeemed or to be redeemed only in part, to
the portion of the Liquidation Amount of Capital Securities that has been or is
to be redeemed.

         SECTION 4.3  Subordination of Common Securities.

         (a) Payment of Distributions (including Additional Amounts, if
applicable) on, and the Redemption Price of, the Trust Securities, as
applicable, shall be made, subject to Section 4.2(f), pro rata among the Common
Securities and the Capital Securities based on the Liquidation Amount of the
Trust Securities; provided, however, that if on any Distribution Date or
Redemption Date any Event of Default resulting from a Debenture Event of Default
shall have occurred and be continuing, no payment of any Distribution (including
Additional Amounts, if applicable) on, or Redemption Price of, any Common
Security, and no other payment on account of the redemption, liquidation or
other acquisition of Common Securities, shall be made unless payment in full in
cash of all accumulated and unpaid Distributions (including Additional 

<PAGE>   27
                                                                              20



Amounts, if applicable) on all Outstanding Capital Securities for all
Distribution periods terminating on or prior thereto, or in the case of payment
of the Redemption Price the full amount of such Redemption Price on all
Outstanding Capital Securities then called for redemption, shall have been made
or provided for, and all funds immediately available to the Property Trustee
shall first be applied to the payment in full in cash of all Distributions
(including Additional Amounts, if applicable) on, or the Redemption Price of,
Capital Securities then due and payable.

         (b) In the case of the occurrence of any Event of Default resulting
from any Debenture Event of Default, the Holder of Common Securities will be
deemed to have waived any right to act with respect to any such Event of Default
under this Trust Agreement until the effect of all such Events of Default with
respect to the Capital Securities have been cured, waived or otherwise
eliminated. Until any such Event of Default under this Trust Agreement with
respect to the Capital Securities has been so cured, waived or otherwise
eliminated, the Property Trustee shall act solely on behalf of the Holders of
the Capital Securities and not the Holder of the Common Securities, and only the
Holders of the Capital Securities will have the right to direct the Property
Trustee to act on their behalf.

         SECTION 4.4  Payment Procedures.

         Payments of Distributions (including Additional Amounts, if applicable)
in respect of the Capital Securities shall be made by wire transfer, direct
deposit or check mailed to the address of the Person entitled thereto as such
address shall appear on the Securities Register or, if the Capital Securities
are held by a Clearing Agency, such Distributions shall be made to the Clearing
Agency in immediately available funds, which shall credit the relevant Persons'
accounts at such Clearing Agency on the applicable Distribution Dates. Payments
in respect of the Common Securities shall be made in such manner as shall be
mutually agreed in writing between the Property Trustee and the Common
Securityholder.

         SECTION 4.5  Tax Returns and Reports.

         The Administrative Trustees shall prepare (or cause to be prepared), at
the Depositor's expense, and file all United States federal, state and local tax
and information returns and reports required to be filed by or in respect of the
Trust. In this regard, the Administrative Trustees shall (a) prepare and file
(or cause to be prepared and filed) the appropriate Internal Revenue Service
Form required to be filed in respect of the Trust in each taxable year of the
Trust and (b) prepare and furnish (or cause to be prepared and furnished) to
each Securityholder the appropriate Internal Revenue Service form, if any, and
the information required to be provided by the Trust on such form. The
Administrative Trustees shall provide the Depositor and the Property Trustee
with a copy of all such returns and reports promptly after such filing or
furnishing. The Trustees shall comply with United

States federal withholding and backup withholding tax laws and information
reporting requirements with respect to any payments to Securityholders under the
Trust Securities.

         SECTION 4.6  Payment of Taxes, Duties, Etc. of the Issuer Trust.

         Upon receipt under the Debentures of Additional Sums, the Property
Trustee shall promptly pay any taxes, duties or governmental charges of
whatsoever nature (other than withholding taxes) imposed on the Trust by the
United States or any other taxing authority.

         SECTION 4.7  Payments under Indenture or Pursuant to Direct Actions.

         Any amount payable hereunder to any Holder of Capital Securities shall
be reduced by the amount of any corresponding payment such Holder (or an Owner
with respect to the Holder's Capital Securities) has directly received pursuant
to Section 5.8 of the Indenture or Section 5.14 of this Trust Agreement.

         SECTION 5.1  Initial Ownership.

         Upon the creation of the Trust and the contribution by the Depositor
pursuant to Section 2.3 and until the issuance of the Trust Securities, and at
any time during which no Trust Securities are outstanding, the Depositor shall
be the sole beneficial owner of the Trust.

         SECTION 5.2  The Trust Securities Certificates.

         The Capital Securities Certificates shall be issued in minimum
denominations of $1,000 Liquidation Amount and integral multiples of $1,000 in
excess thereof, and the Common Securities Certificates shall be issued in
denominations of $1,000 Liquidation Amount and integral multiples thereof. The
Trust Securities Certificates shall be executed on behalf of the Trust by manual
or facsimile signature of at least one Administrative Trustee and, if executed
on behalf of the Trust by facsimile, countersigned by a transfer agent or its
agent. The Capital Securities Certificates shall be authenticated by the
Property Trustee by manual or facsimile signature of an authorized signatory
thereof and, if executed by such authorized signatory of the Property Trustee by
facsimile, countersigned by a transfer agent or its agent. Trust Securities
Certificates bearing the manual signatures of individuals who were, at the time
when such signatures shall have been affixed, authorized to sign on behalf of
the Trust or the Property Trustee or, if executed on behalf of the Trust or the
Property Trustee by facsimile, countersigned by a transfer agent or its agent,
shall be validly issued and entitled to the benefits of this Trust Agreement,
notwithstanding that such individuals or 

<PAGE>   29
                                                                              22



any of them shall have ceased to be so authorized prior to the delivery of such
Trust Securities Certificates or did not hold such offices at the date of
delivery of such Trust Securities Certificates. A transferee of a Trust
Securities Certificate shall become a Securityholder, and shall be entitled to
the rights and subject to the obligations of a Securityholder hereunder, upon
due registration of such Trust Securities Certificate in such transferee's name
pursuant to Sections 5.4, 5.11 and 5.13.

         SECTION 5.3  Execution and Delivery of Trust Securities Certificates.

         On the Closing Date, the Administrative Trustees shall cause Trust
Securities Certificates, in an aggregate Liquidation Amount as provided in
Sections 2.4 and 2.5, to be executed on behalf of the Trust and delivered to or
upon the written order of the Depositor, signed by its chairman of the board,
its chief executive officer, its president, any executive vice president, any
senior vice president or any vice president, treasurer or assistant treasurer or
controller without further corporate action by the Depositor, in authorized
denominations.

         SECTION 5.4 Registration of Transfer and Exchange of Capital Securities
Certificates.

         The Depositor shall keep or cause to be kept, at the office or agency
maintained pursuant to Section 5.8, a register or registers for the purpose of
registering Trust Securities Certificates and transfers and exchanges of Capital
Securities Certificates (the "Securities Register") in which the transfer agent
and registrar designated by the Depositor (the "Securities Registrar"), subject
to such reasonable regulations as it may prescribe, shall provide for the
registration of Capital Securities Certificates and Common Securities
Certificates (subject to Section 5.10 in the case of the Common Securities
Certificates) and registration of transfers and exchanges of Capital Securities
Certificates as herein provided. The Bank shall be the initial Securities
Registrar.

         Upon surrender for registration of transfer of any Capital Securities
Certificate at the office or agency maintained pursuant to Section 5.8, the
Administrative Trustees or any one of them shall execute on behalf of the Trust
(and if executed on behalf of the Trust by a facsimile signature, such
certificate shall be countersigned by a transfer agent or its agent) and
deliver, in the name of the designated transferee or transferees, one or more
new Capital Securities Certificates in authorized denominations of a like
aggregate Liquidation Amount dated the date of execution by such Administrative
Trustee or Trustees. The Securities Registrar shall not be required to register
the transfer of any Capital Securities that have been called for redemption
during a period beginning at the opening of business 15 days before the day of
selection for such redemption.

         At the option of a Holder, Capital Securities Certificates may be
exchanged for other Capital Securities Certificates in authorized denominations
of the same class and of a like aggregate Liquidation Amount upon surrender of
the Capital Securities Certificates to be exchanged at the office or agency
maintained pursuant to Section 5.8.

<PAGE>   30
                                                                              23



         Every Capital Securities Certificate presented or surrendered for
registration of transfer or exchange shall be accompanied by a written
instrument of transfer in form satisfactory to an Administrative Trustee and the
Securities Registrar duly executed by the Holder or his attorney duly authorized
in writing. Each Capital Securities Certificate surrendered for registration of
transfer or exchange shall be cancelled and subsequently disposed of by an
Administrative Trustee or the Securities Registrar in accordance with such
Person's customary practice.

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

         SECTION 5.5 Mutilated, Destroyed, Lost or Stolen Trust Securities
Certificates.

         If (a) any mutilated Trust Securities Certificate shall be surrendered
to the Securities Registrar, or if the Securities Registrar shall receive
evidence to its satisfaction of the destruction, loss or theft of any Trust
Securities Certificate and (b) there shall be delivered to the Securities
Registrar and the Administrative Trustees such security or indemnity as may be
required by them to save each of them harmless, then in the absence of notice
that such Trust Securities Certificate shall have been acquired by a bona fide
purchaser, the Administrative Trustees, or any one of them, on behalf of the
Trust shall execute by manual or facsimile signature and, if executed on behalf
of the Trust by facsimile signature, such certificate shall be countersigned by
a transfer agent, and make available for delivery, in exchange for or in lieu of
any such mutilated, destroyed, lost or stolen Trust Securities Certificate, a
new Trust Securities Certificate of like class, tenor and denomination. In
connection with the issuance of any new Trust Securities Certificate under this
Section , the Administrative Trustees or the Securities Registrar may require 
the payment of a sum sufficient to cover any tax or other governmental charge 
that may be imposed in connection therewith. Any duplicate Trust Securities
Certificate issued pursuant to this Section shall constitute conclusive evidence
of an undivided beneficial interest in the Trust Property, as if originally
issued, whether or not the lost, stolen or destroyed Trust Securities
Certificate shall be found at any time.

         SECTION 5.6  Persons Deemed Securityholders.

         The Trustees or the Securities Registrar shall treat the Person in
whose name any Trust Securities Certificate shall be registered in the
Securities Register as the owner of such Trust Securities Certificate for the
purpose of receiving Distributions and for all other purposes whatsoever, and
neither the Trustees nor the Securities Registrar shall be bound by any notice
to the contrary.

                                                                              24




         SECTION 5.7  Access to List of Securityholders' Names and Addresses.

         Each Holder and each Owner shall be deemed to have agreed not to hold
the Depositor, the Property Trustee or the Administrative Trustees accountable
by reason of the disclosure of its name and address, regardless of the source
from which such information was derived.

         SECTION 5.8  Maintenance of Office or Agency.

         The Administrative Trustees shall maintain an office or offices or
agency or agencies where Capital Securities Certificates may be surrendered for
registration of transfer or exchange and where notices and demands to or upon
the Trustees in respect of the Trust Securities Certificates may be served. The
Administrative Trustees initially designate The Bank of New York, 101 Barclay
Street, Floor 21 West, New York, New York 10286, Attn: Corporate Trust
Administration, as its principal corporate trust office for such purposes. The
Administrative Trustees shall give prompt written notice to the Depositor, the
Property Trustee and to the Securityholders of any change in the location of the
Securities Register or any such office or agency.

         SECTION 5.9  Appointment of Paying Agent.

         The Paying Agent shall make Distributions to Securityholders from the
Payment Account and shall report the amounts of such Distributions to the
Property Trustee and the Administrative Trustees. Any Paying Agent shall have
the revocable power to withdraw funds from the Payment Account for the purpose
of making the Distributions referred to above. The Administrative Trustees may
revoke such power and remove the Paying Agent if such Trustees determine in
their sole discretion that the Paying Agent shall have failed to perform its
obligations under this Trust Agreement in any material respect. The Paying Agent
shall initially be the Bank, and any co-paying agent chosen by the Bank, and
acceptable to the Administrative Trustees and the Depositor. Any Person acting
as Paying Agent shall be permitted to resign as Paying Agent upon 30 days'
written notice to the Administrative Trustees, the Property Trustee and the
Depositor. In the event that the Bank shall no longer be the Paying Agent or a
successor Paying Agent shall resign or its authority to act be revoked, the
Administrative Trustees shall appoint a successor that is acceptable to the
Property Trustee and the Depositor to act as Paying Agent (which shall be a bank
or trust company). The Administrative Trustees shall cause such successor Paying
Agent or any additional Paying Agent appointed by the Administrative Trustees to
execute and deliver to the Trustees an instrument in which such successor Paying
Agent or additional Paying Agent shall agree with the Trustees that as Paying
Agent, such successor Paying Agent or additional Paying Agent will hold all
sums, if any, held by it for payment to the Securityholders in trust for the
benefit of the Securityholders entitled thereto until such sums shall be paid to
such Securityholders. The Paying Agent shall return all unclaimed funds to the
Property Trustee and upon resignation or removal of a Paying Agent such Paying
Agent shall also return all funds in its possession to the Property Trustee. The
provisions of Sections 8.1, 8.3 and 8.6 

<PAGE>   32
                                                                              25



herein shall apply to the Bank also in its role as Paying Agent, for so long as
the Bank shall act as Paying Agent and, to the extent applicable, to any other
paying agent appointed hereunder, and any Paying Agent shall be bound by the
requirements with respect to paying agents of securities issued pursuant to the
Trust Indenture Act. Any reference in this Agreement to the Paying Agent shall
include any co-paying agent unless the context requires otherwise.

         SECTION 5.10  Ownership of Common Securities by Depositor.

         On the Closing Date, the Depositor shall acquire and retain beneficial
and record ownership of the Common Securities. To the fullest extent permitted
by law, other than a transfer in connection with a consolidation or merger of
the Depositor into another Person, any conveyance, transfer or lease by the
Depositor of its properties and assets substantially as an entirety to any
Person, pursuant to Section 8.1 of the Indenture, or a transfer to a wholly
owned subsidiary of the Depositor, any attempted transfer of the Common
Securities shall be void. The Administrative Trustees shall cause each Common
Securities Certificate issued to the Depositor to contain a legend stating "THIS
CERTIFICATE IS NOT TRANSFERABLE TO A PERSON WHO IS NOT A WHOLLY OWNED SUBSIDIARY
OF HOLDER".

         SECTION 5.11 Book-Entry Capital Securities Certificates; Common
Securities Certificate.

         (a) The Capital Securities Certificates, upon original issuance, will
be issued in the form of a typewritten Capital Securities Certificate or
Certificates representing Book-Entry Capital Securities, to be delivered to The
Depository Trust Company, the initial Clearing Agency, by, or on behalf of, the
Trust. Such Capital Securities Certificate or Certificates shall initially be
registered on the Securities Register in the name of Cede & Co., the nominee of
the initial Clearing Agency, and no Owner will receive a Definitive Capital
Securities Certificate representing such Owner's interest in such Capital
Securities, except as provided in Section 5.13. Unless and until Definitive
Capital Securities Certificates have been issued to Owners pursuant to Section
5.13:

                        (i) the provisions of this Section 5.11(a) shall be in
         full force and effect;

                        (ii) the Securities Registrar and the Trustees shall be
         entitled to deal with the Clearing Agency for all purposes of this
         Trust Agreement relating to the Book-Entry Capital Securities
         (including the payment of the Liquidation Amount of and Distributions
         on the Capital Securities evidenced by Book-Entry Capital Securities
         Certificates and the giving of instructions or directions to Owners of
         Capital Securities evidenced by Book-Entry Capital Securities
         Certificates) as the sole Holder of Capital Securities evidenced by
         Book-Entry Capital Securities Certificates and shall have no
         obligations to the Owners thereof;
<PAGE>   33
                                                                              26



                       (iii) to the extent that the provisions of this Section
         5.11 conflict with any other provisions of this Trust Agreement, the
         provisions of this Section 5.11 shall control; and

                        (iv) the rights of the Owners of the Book-Entry Capital
         Securities Certificates shall be exercised only through the Clearing
         Agency and shall be limited to those established by law and agreements
         between such Owners and the Clearing Agency and/or the Clearing Agency
         Participants. Pursuant to the Certificate Depository Agreement, unless
         and until Definitive Capital Securities Certificates are issued
         pursuant to Section 5.13, the initial Clearing Agency will make
         book-entry transfers among the Clearing Agency Participants and receive
         and transmit payments on the Capital Securities to such Clearing Agency
         Participants.

         (b) A single Common Securities Certificate representing the Common
Securities shall be issued to the Depositor in the form of a definitive Common
Securities Certificate.

         SECTION 5.12  Notices to Clearing Agency.

         To the extent that a notice or other communication to the Owners is
required under this Trust Agreement, unless and until Definitive Capital
Securities Certificates shall have been issued to Owners pursuant to Section
5.13, the Trustees shall give all such notices and communications specified
herein to be given to Owners to the Clearing Agency, and shall have no
obligations to the Owners.

         SECTION 5.13  Definitive Capital Securities Certificates.

         If (a) the Depositor advises the Trustees in writing that the Clearing
Agency is no longer willing or able to properly discharge its responsibilities
with respect to the Capital Securities Certificates, and the Depositor is unable
to locate a qualified successor, (b) the Depositor at its option advises the
Trustees in writing that it elects to terminate the book-entry system through
the Clearing Agency or (c) after the occurrence of a Debenture Event of Default,
Owners of Capital Securities Certificates representing beneficial interests
aggregating at least a majority of the Liquidation Amount advise the
Administrative Trustees in writing that the continuation of a book-entry system
through the Clearing Agency is no longer in the best interest of the Owners of
Capital Securities Certificates, then the Administrative Trustees shall notify
the other Trustees and the Clearing Agency, and the Clearing Agency, in
accordance with its customary rules and procedures, shall notify all Clearing
Agency Participants for whom it holds Capital Securities of the occurrence of
any such event and of the availability of the Definitive Capital Securities
Certificates to Owners of such class or classes, as applicable, requesting the
same. Upon surrender to the Administrative Trustees of the typewritten Capital
Securities Certificate or Certificates representing the Book-Entry Capital
Securities by the Clearing Agency, accompanied by registration instructions, the
Administrative Trustees, or any one of them, shall execute the Definitive
Capital Securities Certificates in accordance with the instructions of the
Clearing 

<PAGE>   34
                                                                              27


Agency which, if executed on behalf of the Trust by facsimile, shall be
countersigned by a transfer agent or its agent. Neither the Securities Registrar
nor the Trustees shall be liable for any delay in delivery of such instructions
and may conclusively rely on, and shall be protected in relying on, such
instructions. Upon the issuance of Definitive Capital Securities Certificates,
the Trustees shall recognize the Holders of the Definitive Capital Securities
Certificates as Securityholders. The Definitive Capital Securities Certificates
shall be typewritten, printed, lithographed or engraved or may be produced in
any other manner as is reasonably acceptable to the Administrative Trustees that
meets the requirements of any stock exchange or automated quotation system on
which the Capital Securities are then listed or approved for trading, as
evidenced by the execution thereof by the Administrative Trustees or any one of
them.

         SECTION 5.14  Rights of Securityholders.

         (a) The legal title to the Trust Property is vested exclusively in the
Property Trustee (in its capacity as such) in accordance with Section 2.9, and
the Securityholders shall not have any right or title therein other than the
undivided beneficial ownership interest in the assets of the Trust conferred by
their Trust Securities and they shall have no right to call for any partition or
division of property, profits or rights of the Trust except as described below.
The Trust Securities shall be personal property giving only the rights
specifically set forth therein and in this Trust Agreement. The Trust Securities
shall have no preemptive or similar rights and when issued and delivered to
Securityholders against payment of the purchase price therefor will be fully
paid and nonassessable by the Trust. The Holders of the Capital Securities, in
their capacities as such, shall be entitled to the same limitation of personal
liability extended to stockholders of private corporations for profit organized
under the General Corporation Law of the State of Delaware.

         (b) For so long as any Capital Securities remain Outstanding, if, upon
a Debenture Event of Default, the Debenture Trustee fails or the holders of not
less than 25% in principal amount of the outstanding Debentures fail to declare
the principal of all of the Debentures to be immediately due and payable, the
Holders of at least 25% in Liquidation Amount of the Capital Securities then
Outstanding shall have such right by a notice in writing to the Depositor and
the Debenture Trustee; and upon any such declaration such principal amount of
and the accrued interest on all of the Debentures shall become immediately due
and payable as set forth in the Indenture, provided that the payment of
principal, premium and interest on such Debentures shall remain subordinated to
the extent provided in the Indenture.

         At any time after such a declaration of acceleration with respect to
the Debentures has been made and before a judgment or decree for payment of the
money due has been obtained by the Debenture Trustee as in the Indenture
provided, the Holders of a majority in Liquidation Amount of the Capital
Securities, by written notice to the Property Trustee, the Depositor and the
Debenture Trustee, may rescind and annul such declaration and its consequences
if:
<PAGE>   35
                                                                              28



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

                           (A) all overdue installments of interest (including
                  any Additional Interest (as defined in the Indenture)) on all
                  of the Debentures,

                           (B) the principal of (and premium, if any, on) any
                  Debentures which have become due otherwise than by such
                  declaration of acceleration and interest thereon at the rate
                  borne by the Debentures, and

                           (C) all sums paid or advanced by the Debenture
                  Trustee under the Indenture and the reasonable compensation,
                  expenses, disbursements and advances of the Debenture Trustee
                  and the Property Trustee, their agents and counsel; and

                        (ii) all Events of Default with respect to the
         Debentures, other than the non-payment of the principal of the
         Debentures which has become due solely by such acceleration, have been
         cured or waived as provided in Section 5.13 of the Indenture.

         The holders of a majority in aggregate Liquidation Amount of the
Capital Securities may, on behalf of the Holders of all the Capital Securities,
waive any past default under the Indenture, except a default in the payment of
principal, premium or interest (unless all Events of Default with respect to the
Debentures, other than the non-payment of the principal of the Debentures which
has become due solely by such acceleration, have been cured or annulled as
provided in Section 5.3 of the Indenture and the Company has paid or deposited
with the Debenture Trustee a sum sufficient to pay all overdue installments of
interest (including any Additional Interest (as defined in the Indenture)) on
the Debentures, the principal of (and premium, if any, on) any Debentures which
have become due otherwise than by such declaration of acceleration and interest
thereon at the rate borne by the Debentures, and all sums paid or advanced by
the Debenture Trustee under the Indenture and the reasonable compensation,
expenses, disbursements and advances of the Debenture Trustee and the Property
trustee, their agents and counsel) or a default in respect of a covenant or
provision which under the Indenture cannot be modified or amended without the
consent of the holder of each outstanding Debenture. No such rescission shall
affect any subsequent default or impair any right consequent thereon.

         Upon receipt by the Property Trustee of written notice declaring such
an acceleration, or rescission and annulment thereof, by Holders of the Capital
Securities all or part of which is represented by Book-Entry Capital Securities
Certificates, a record date shall be established for determining Holders of
Outstanding Capital Securities entitled to join in such notice, which record
date shall be at the close of business on the day the Property Trustee receives
such notice. The Holders of Outstanding Capital Securities on such record date,
or their duly designated proxies, and only such Persons, shall be entitled to
join in such notice, 

<PAGE>   36
                                                                              29



whether or not such Holders remain Holders after such record date; provided,
that, unless such declaration of acceleration, or rescission and annulment, as
the case may be, shall have become effective by virtue of the requisite
percentage having joined in such notice prior to the day which is 90 days after
such record date, such notice of declaration of acceleration, or rescission and
annulment, as the case may be, shall automatically and without further action by
any Holder be canceled and of no further effect. Nothing in this paragraph shall
prevent a Holder, or a proxy of a Holder, from giving, after expiration of such
90-day period, a new written notice of declaration of acceleration, or
rescission and annulment thereof, as the case may be, that is identical to a
written notice which has been canceled pursuant to the proviso to the preceding
sentence, in which event a new record date shall be established pursuant to the
provisions of this Section 5.14(b).

         (c) For so long as any Capital Securities remain Outstanding, to the
fullest extent permitted by law and subject to the terms of this Trust Agreement
and the Indenture, upon a Debenture Event of Default specified in Section 5.1(1)
or 5.1(2) of the Indenture, any Holder of Capital Securities shall have the
right to institute a proceeding directly against the Depositor, pursuant to
Section 5.8 of the Indenture, for enforcement of payment to such Holder of the
principal amount of or premium or interest on Debentures having a principal
amount equal to the Liquidation Amount of the Capital Securities of such Holder
(a "Direct Action"). Except as set forth in Section 5.14(b) and this Section
5.14(c), the Holders of Capital Securities shall have no right to exercise
directly any right or remedy available to the holders of, or in respect of, the
Debentures.

         SECTION 5.15  CUSIP Numbers.

         The Administrative Trustees in issuing the Capital Securities may use
"CUSIP" numbers (if then generally in use), and, if so, the Property Trustee
shall use "CUSIP" numbers in notices of redemption as a convenience to Holders;
provided that any such notice may state that no representation is made as to the
correctness of such numbers either as printed on the Capital Securities or as
contained in any notice of a redemption and that reliance may be placed only on
the other identification numbers printed on the Capital Securities, and any such
redemption shall not be affected by any defect in or omission of such numbers.
The Administrative Trustees will promptly notify the Property Trustee of any
change in the CUSIP numbers.

                                   ARTICLE VI

                    ACTS OF SECURITYHOLDERS; MEETINGS; VOTING

         SECTION 6.1  Limitations on Voting Rights.

         (a) Except as provided in this Section, in Sections 5.14, 8.10 and 
10.3 and in the Indenture and as otherwise required by law, no Holder of Capital
Securities shall have any right to vote or in any manner otherwise control the
administration, operation and management of the Trust or the obligations of the
parties hereto, nor shall anything herein set forth, or contained in the terms
of the Trust Securities Certificates, be construed so as to constitute the
Securityholders from time to time as partners or members of an association.

         (b) So long as any Debentures are held by the Property Trustee, the
Trustees shall not (i) direct the time, method and place of conducting any
proceeding for any remedy available to the Debenture Trustee, or executing any
trust or power conferred on the Debenture Trustee with respect to such
Debentures, (ii) waive any past default which is waiveable under Section 5.13 of
the Indenture, (iii) exercise any right to rescind or annul a declaration that
the principal of all the Debentures shall be due and payable or (iv) consent to
any amendment, modification or termination of the Indenture or the Debentures,
where such consent shall be required, without, in each case, obtaining the prior
approval of the Holders of at least a majority in Liquidation Amount of all
Outstanding Capital Securities, provided, however, that where a consent under
the Indenture would require the consent of each holder of Debentures affected
thereby, no such consent shall be given by the Property Trustee without the
prior written consent of each Holder of Capital Securities. The Trustees shall
not revoke any action previously authorized or approved by a vote of the Holders
of Capital Securities, except by a subsequent vote of the Holders of Capital
Securities. The Property Trustee shall notify all Holders of the Capital
Securities of any notice of default received from the Debenture Trustee with
respect to the Debentures. In addition to obtaining the foregoing approvals of
the Holders of the Capital Securities, prior to taking any of the foregoing
actions, the Administrative Trustees shall, at the expense of the Depositor,
obtain an Opinion of Counsel experienced in such matters to the effect that such
action shall not cause the Trust to fail to be classified as a grantor trust or
cause the Trust to be taxable as a corporation for United States federal income
tax purposes.

         (c) If any proposed amendment to the Trust Agreement provides for, or
the Trustees otherwise propose to effect, (i) any action that would adversely
affect in any material respect the powers, preferences or special rights of the
Capital Securities, whether by way of amendment to the Trust Agreement or
otherwise, or (ii) the dissolution, winding-up or termination of the Trust,
other than pursuant to the terms of this Trust Agreement, then the Holders of
Outstanding Capital Securities as a class will be entitled to vote on such
amendment or proposal and such amendment or proposal shall not be effective
except with the approval of the Holders of at least a majority in Liquidation
Amount of the Outstanding Capital Securities. Notwithstanding any other
provision of this Trust Agreement, no 
<PAGE>   38
                                                                              31



amendment to this Trust Agreement may be made if, as a result of such amendment,
it would cause the Trust to fail to be classified as a grantor trust or to be
taxable as a corporation for United States federal income tax purposes.

         SECTION 6.2  Notice of Meetings.

         Notice of all meetings of the Capital Securityholders, stating the
time, place and purpose of the meeting, shall be given by the Property Trustee
pursuant to Section 10.9 to each Capital Securityholder of record, at his
registered address, at least 15 days and not more than 90 days before the
meeting. At any such meeting, any business properly before the meeting may be so
considered whether or not stated in the notice of the meeting. Any adjourned
meeting may be held as adjourned without further notice.

         SECTION 6.3  Meetings of Capital Securityholders.

         No annual meeting of Securityholders is required to be held. The
Administrative Trustees, however, shall call a meeting of Capital
Securityholders to vote on any matter upon the written request of the Capital
Securityholders of record of 25% of the Outstanding Capital Securities (based
upon their Liquidation Amount) and the Administrative Trustees or the Property
Trustee may, at any time in their discretion, call a meeting of Capital
Securityholders to vote on any matters as to which Capital Securityholders are
entitled to vote.

         Capital Securityholders of record of 50% of the Outstanding Capital
Securities (based upon their Liquidation Amount), present in person or by proxy,
shall constitute a quorum at any meeting of Capital Securityholders.

         If a quorum is present at a meeting, an affirmative vote by the Capital
Securityholders of record present, in person or by proxy, holding at least a
majority of the Outstanding Capital Securities (based upon their Liquidation
Amount) held by holders of record of Outstanding Capital Securities present,
either in person or by proxy, at such meeting shall constitute the action of the
Capital Securityholders, unless this Trust Agreement requires a greater number
of affirmative votes.

         SECTION 6.4  Voting Rights.

         Securityholders shall be entitled to one vote for each $1,000 of
Liquidation Amount represented by their Trust Securities in respect of any
matter as to which such Securityholders are entitled to vote.
<PAGE>   39
                                                                              32



         SECTION 6.5  Proxies, etc.

         At any meeting of Securityholders, any Securityholder entitled to vote
thereat may vote by proxy, provided that no proxy shall be voted at any meeting
unless it shall have been placed on file with the Administrative Trustees, or
with such other officer or agent of the Trust as the Administrative Trustees may
direct, for verification prior to the time at which such vote shall be taken.
Pursuant to a resolution of the Property Trustee, proxies may be solicited in
the name of the Property Trustee or one or more officers of the Property
Trustee. Only Securityholders of record shall be entitled to vote. When Trust
Securities are held jointly by several Persons, any one of them may vote at any
meeting in person or by proxy in respect of such Trust Securities, but if more
than one of them shall be present at such meeting in person or by proxy, and
such joint owners or their proxies so present disagree as to any vote to be
cast, such vote shall not be received in respect of such Trust Securities. A
proxy purporting to be executed by or on behalf of a Securityholder shall be
deemed valid unless challenged at or prior to its exercise, and the burden of
proving invalidity shall rest on the challenger. No proxy shall be valid more
than three years after its date of execution.

         SECTION 6.6  Securityholder Action by Written Consent.

         Any action which may be taken by Securityholders at a meeting may be
taken without a meeting if Securityholders holding at least a majority of all
Outstanding Trust Securities (based upon their Liquidation Amount) entitled to
vote in respect of such action (or such larger proportion thereof as shall be
required by any express provision of this Trust Agreement) shall consent to the
action in writing.

         SECTION 6.7  Record Date for Voting and Other Purposes.

         For the purposes of determining the Securityholders who are entitled to
notice of and to vote at any meeting or by written consent, or to participate in
any Distribution on the Trust Securities in respect of which a record date is
not otherwise provided for in this Trust Agreement, or for the purpose of any
other action, the Administrative Trustees may from time to time fix a date, not
more than 90 days prior to the date of any meeting of Securityholders or the
payment of a Distribution or other action, as the case may be, as a record date
for the determination of the identity of the Securityholders of record for such
purposes.

         SECTION 6.8  Acts of Securityholders.

         Any request, demand, authorization, direction, notice, consent, waiver
or other action provided or permitted by this Trust Agreement to be given, made
or taken by Securityholders or Owners may be embodied in and evidenced by one or
more instruments of substantially similar tenor signed by such Securityholders
or Owners in person or by an agent duly appointed in writing; and, except as
otherwise expressly provided herein, such action shall become effective when
such instrument or instruments are delivered to an Administrative 
<PAGE>   40
                                                                              33



Trustee. Such instrument or instruments (and the action embodied therein and
evidenced thereby) are herein sometimes referred to as the "Act" of the
Securityholders or Owners signing such instrument or instruments. Proof of
execution of any such instrument or of a writing appointing any such agent shall
be sufficient for any purpose of this Trust Agreement and (subject to Section
8.1) conclusive in favor of the Trustees, if made in the manner provided in this
Section.

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

         The ownership of Capital Securities shall be proved by the Securities
Register.

         Any request, demand, authorization, direction, notice, consent, waiver
or other Act of the Securityholder of any Trust Security shall bind every future
Securityholder of the same Trust Security and the Securityholder of every Trust
Security issued upon the registration of transfer thereof or in exchange
therefor or in lieu thereof in respect of anything done, omitted or suffered to
be done by the Trustees or the Trust in reliance thereon, whether or not
notation of such action is made upon such Trust Security.

         Without limiting the foregoing, a Securityholder entitled hereunder to
take any action hereunder with regard to any particular Trust Security may do so
with regard to all or any part of the Liquidation Amount of such Trust Security
or by one or more duly appointed agents each of which may do so pursuant to such
appointment with regard to all or any part of such Liquidation Amount.

         If any dispute shall arise between the Securityholders and the
Administrative Trustees or among such Securityholders or Trustees with respect
to the authenticity, validity or binding nature of any request, demand,
authorization, direction, consent, waiver or other Act of such Securityholder or
Trustee under this Article VI, then the determination of such matter by the
Property Trustee shall be conclusive with respect to such matter.

         SECTION 6.9  Inspection of Records.

         Upon reasonable notice to the Administrative Trustees and the Property
Trustee, the records of the Trust shall be open to inspection by Securityholders
during normal business hours for any purpose reasonably related to such
Securityholder's interest as a Securityholder.

         (c) the Delaware Trustee is a Delaware banking corporation duly

         (f) the execution, delivery and performance of this Trust Agreement has
been duly authorized by all necessary corporate or other action on the part of

         (g) neither the authorization, execution or delivery by the Property

Trust or would question the right, power and authority of the Property Trustee
or the Delaware Trustee, as the case may be, to enter into or perform its
obligations as one of the Trustees under this Trust Agreement.

         SECTION 7.2  Representations and Warranties of Depositor.

         The Depositor hereby represents and warrants for the benefit of the
Securityholders that:

                                  ARTICLE VIII

                                  THE TRUSTEES

         SECTION 8.1  Certain Duties and Responsibilities.

         (a) The duties and responsibilities of the Trustees shall be as
provided by this Trust Agreement and, in the case of the Property Trustee, by
the Trust Indenture Act. Notwithstanding the foregoing, no provision of this
Trust Agreement shall require the Trustees to expend or risk their own funds or
otherwise incur any financial liability in the performance of any of their
duties hereunder, or in the exercise of any of their rights or powers, if they
shall have reasonable grounds for believing that repayment of such funds or
adequate indemnity against such risk or liability is not reasonably assured to
them. Whether or not therein expressly so provided, every provision of this
Trust Agreement relating to the conduct or affecting the liability of or
affording protection to the Trustees shall be subject to the provisions of this
Section. Nothing in this Trust Agreement shall be construed to release an
Administrative Trustee from liability for its own gross negligent action, its
own gross negligent failure to act, or its own willful misconduct. To the extent
that, at law or in equity, an Administrative Trustee has duties (including
fiduciary duties) and liabilities relating thereto to the Trust or to the
Securityholders, such Administrative Trustee shall not be liable to the Trust or
to any Securityholder for such Trustee's good faith reliance on the provisions
of this Trust Agreement. The provisions of this Trust Agreement, to the extent
that they restrict the duties and liabilities of the Administrative Trustees
otherwise existing at law or in equity, are agreed by the Depositor and the
Securityholders to replace such other duties and liabilities of the
Administrative Trustees.

         (b) All payments made by the Property Trustee or a Paying Agent in
respect of the Trust Securities shall be made only from the revenue and proceeds
from the Trust Property and only to the extent that there shall be sufficient
revenue or proceeds from the Trust Property to enable the Property Trustee or a
Paying Agent to make payments in accordance with the terms hereof. Each
Securityholder, by its acceptance of a Trust Security, agrees that it will look
solely to the revenue and proceeds from the Trust Property to the extent legally
available for distribution to it as herein provided and that the Trustees are
not personally liable to it for any amount distributable in respect of any Trust
Security or for any other liability in respect of any Trust Security. This
Section 8.1(b) does not limit the liability of the Trustees expressly set forth
elsewhere in this Trust Agreement or, in the case of the Property Trustee, in
the Trust Indenture Act.

         (c) No provision of this Trust Agreement shall be construed to relieve
the Property Trustee from liability for its own negligent action, its own
negligent failure to act, or its own willful misconduct, except that:
<PAGE>   44
                                                                              37


                         (i) the Property Trustee shall not be liable for any
         error of judgment made in good faith by an authorized officer of the
         Property Trustee, unless it shall be proved that the Property Trustee
         was negligent in ascertaining the pertinent facts;

                        (ii) the Property Trustee shall not be liable with
         respect to any action taken or omitted to be taken by it in good faith
         in accordance with the direction of the Holders of not less than a
         majority in Liquidation Amount of the Trust Securities relating to the
         time, method and place of conducting any proceeding for any remedy
         available to the Property Trustee, or exercising any trust or power
         conferred upon the Property Trustee under this Trust Agreement;

                       (iii) the Property Trustee's sole duty with respect to
         the custody, safe keeping and physical preservation of the Debentures
         and the Payment Account shall be to deal with such property in a
         similar manner as the Property Trustee deals with similar property for
         its own account, subject to the protections and limitations on
         liability afforded to the Property Trustee under this Trust Agreement
         and the Trust Indenture Act;

                        (iv) the Property Trustee shall not be liable for any
         interest on any money received by it except as it may otherwise agree
         in writing with the Depositor; and money held by the Property Trustee
         need not be segregated from other funds held by it except in relation
         to the Payment Account maintained by the Property Trustee pursuant to
         Section 3.1 and except to the extent otherwise required by law; and

                         (v) the Property Trustee shall not be responsible for
         monitoring the compliance by the Administrative Trustees or the
         Depositor with their respective duties under this Trust Agreement, nor
         shall the Property Trustee be liable for the default or misconduct of
         the Administrative Trustees or the Depositor.

         SECTION 8.2  Certain Notices.

         Within ten Business Days after the occurrence of any Event of Default
actually known to the Property Trustee, the Property Trustee shall transmit, in
the manner and to the extent provided in Section 10.9, notice of such Event of
Default to the Securityholders, the Administrative Trustees and the Depositor,
unless such Event of Default shall have been cured or waived.

         Within five Business Days after the receipt of notice of the
Depositor's exercise of its right to defer the payment of interest on the
Debentures pursuant to the Indenture, the Administrative Trustee shall transmit,
in the manner and to the extent provided in Section 10.9, notice of such
exercise to the Securityholders and the Property Trustee, unless such exercise
shall have been revoked.

         SECTION 8.3  Certain Rights of Property Trustee.

         Subject to the provisions of Section 8.1:

         (a) the Property Trustee may rely and shall be protected in acting or
refraining from acting in good faith upon any resolution, Opinion of Counsel,
certificate, written representation of a Holder or transferee, certificate of
auditors or any other certificate, statement, instrument, opinion, report,
notice, request, consent, order, appraisal, bond, debenture, note, other
evidence of indebtedness or other paper or document believed by it to be genuine
and to have been signed or presented by the proper party or parties;

         (b) if (i) in performing its duties under this Trust Agreement the
Property Trustee is required to decide between alternative courses of action or
(ii) in construing any of the provisions of this Trust Agreement the Property
Trustee finds the same ambiguous or inconsistent with any other provisions
contained herein or (iii) the Property Trustee is unsure of the application of
any provision of this Trust Agreement, then, except as to any matter as to which
the Capital Securityholders are entitled to vote under the terms of this Trust
Agreement, the Property Trustee shall deliver a notice to the Depositor
requesting written instructions of the Depositor as to the course of action to
be taken and the Property Trustee shall take such action, or refrain from taking
such action, as the Property Trustee shall be instructed in writing to take, or
to refrain from taking, by the Depositor; provided, however, that if the
Property Trustee does not receive such instructions of the Depositor within ten
Business Days after it has delivered such notice, or such reasonably shorter
period of time set forth in such notice (which to the extent practicable shall
not be less than two Business Days), it may, but shall be under no duty to, take
or refrain from taking such action not inconsistent with this Trust Agreement as
it shall deem advisable and in the best interests of the Securityholders, in
which event the Property Trustee shall have no liability except for its own bad
faith, negligence or willful misconduct;


         (c) any direction or act of the Depositor or the Administrative
Trustees contemplated by this Trust Agreement shall be sufficiently evidenced by
an Officers' Certificate;

         (d) whenever in the administration of this Trust Agreement, the
Property Trustee shall deem it desirable that a matter be established before
undertaking, suffering or omitting any action hereunder, the Property Trustee
(unless other evidence is herein specifically prescribed) may, in the absence of
bad faith on its part, request and rely upon an Officers' Certificate which,
upon receipt of such request, shall be promptly delivered by the Depositor or
the Administrative Trustees;

         (e) the Property Trustee shall have no duty to see to any recording,
filing or registration of any instrument (including any financing or
continuation statement or any filing under tax or securities laws) or any
rerecording, refiling or reregistration thereof;

                                                                              39



         (f) the Property Trustee may consult with counsel of its selection
(which counsel may be counsel to the Depositor or any of its Affiliates, and may
include any of its employees) and the advice of such counsel shall be full and
complete authorization and protection in respect of any action taken, suffered
or omitted by it hereunder in good faith and in reliance thereon and in
accordance with such advice; the Property Trustee shall have the right at any
time to seek instructions concerning the administration of this Trust Agreement
from any court of competent jurisdiction;

         (g) the Property Trustee shall be under no obligation to exercise any
of the rights or powers vested in it by this Trust Agreement at the request or
direction of any of the Securityholders pursuant to this Trust Agreement, unless
such Securityholders shall have offered to the Property Trustee reasonable
security or indemnity against the costs, expenses and liabilities which might be
incurred by it in compliance with such request or direction;

         (h) the Property Trustee shall not be bound to make any investigation
into the facts or matters stated in any resolution, certificate, statement,
instrument, opinion, report, notice, request, consent, order, approval, bond,
debenture, note or other evidence of indebtedness or other paper or document,
unless requested in writing to do so by one or more Securityholders, but the
Property Trustee may make such further inquiry or investigation into such facts
or matters as it may see fit;

         (i) the Property Trustee may execute any of the trusts or powers

         (j) whenever in the administration of this Trust Agreement the Property
Trustee shall deem it desirable to receive written instructions with respect to
enforcing any remedy or right or taking any other action hereunder the Property
Trustee (i) may request written instructions from the Holders of the Trust
Securities which written instructions may only be given by the Holders of the
same proportion in Liquidation Amount of the Trust Securities as would be
entitled to direct the Property Trustee under the terms of the Trust Securities
in respect of such remedy, right or action, (ii) may refrain from enforcing such
remedy or right or taking such other action until such written instructions are

         (k) except as otherwise expressly provided by this Trust Agreement, the
Property Trustee shall not be under any obligation to take any action that is
discretionary under the provisions of this Trust Agreement.

         No provision of this Trust Agreement shall be deemed to impose any duty
or obligation on the Property Trustee to perform any act or acts or exercise any
right, power, duty or obligation conferred or imposed on it, in any jurisdiction
in which it shall be illegal, or in which the Property Trustee shall be
unqualified or incompetent in accordance with 
<PAGE>   47
                                                                              40



applicable law, to perform any such act or acts, or to exercise any such right,
power, duty or obligation. No permissive power or authority available to the
Property Trustee shall be construed to be a duty.

         SECTION 8.4  Not Responsible for Recitals or Issuance of Securities.

         The recitals contained herein and in the Trust Securities Certificates
shall be taken as the statements of the Trust, and the Trustees do not assume
any responsibility for their correctness. The Trustees shall not be accountable
for the use or application by the Depositor of the proceeds of the Debentures.

         SECTION 8.5  May Hold Securities.

         Any Trustee or any other agent of any Trustee or the Trust, in its
individual or any other capacity, may become the owner or pledgee of Trust
Securities and, subject to Sections 8.8 and 8.13, except as provided in the
definition of the term "Outstanding" in Article I, may otherwise deal with the
Trust with the same rights it would have if it were not a Trustee or such other
agent.

         SECTION 8.6  Compensation; Indemnity; Fees.

         The Holder of the Common Securities shall:

         (a) pay to the Trustees from time to time such compensation as shall be
agreed in writing with the Holder of the Common Securities for all services
rendered by them hereunder (which compensation shall not be limited by any
provision of law in regard to the compensation of a trustee of an express
trust);

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

         (c) to the fullest extent permitted by applicable law, indemnify and
hold harmless (i) each Trustee, (ii) any Affiliate of any Trustee, (iii) any
officer, director, shareholder, employee, representative or agent of any
Trustee, and (iv) any employee or agent of the Trust or its Affiliates,
(referred to herein as an "Indemnified Person") from and against any and all
loss, damage, liability, tax, penalty, expense or claim of any kind or nature
whatsoever incurred by such Indemnified Person by reason of the creation,
operation or termination of the Trust or any act or omission performed or
omitted by such Indemnified Person in good faith on behalf of the Trust and in a
manner such Indemnified Person reasonably believed to be within the scope of
authority conferred on such Indemnified Person by this Trust Agreement, except
that no Indemnified Person shall be entitled to be 
<PAGE>   48
                                                                              41

indemnified in respect of any loss, damage or claim incurred by such Indemnified
Person by reason of negligence or willful misconduct with respect to such acts
or omissions. When the Property Trustee incurs expenses or renders services in
connection with an Event of Default specified in Section 5.1(4) or Section
5.1(5) of the Indenture, the expenses (including the reasonable charges and
expenses of its counsel) and the compensation for the services are intended to
constitute expenses of administration under any applicable federal or state
bankruptcy, insolvency or other similar law.

         The provisions of this Section 8.6 shall survive the termination of
this Trust Agreement.

         No Trustee may claim any lien or charge on any Trust Property as a
result of any amount due pursuant to this Section 8.6.

         The Depositor and any Trustee (in the case of the Property Trustee,
subject to Section 8.8 hereof) may engage in or possess an interest in other
business ventures of any nature or description, independently or with others,
similar or dissimilar to the business of the Trust, and the Trust and the
Holders of Trust Securities shall have no rights by virtue of this Trust
Agreement in and to such independent ventures or the income or profits derived
therefrom, and the pursuit of any such venture, even if competitive with the
business of the Trust, shall not be deemed wrongful or improper. Neither the
Depositor, nor any Trustee, shall be obligated to present any particular
investment or other opportunity to the Trust even if such opportunity is of a
character that, if presented to the Trust, could be taken by the Trust, and the
Depositor or any Trustee shall have the right to take for its own account
(individually or as a partner or fiduciary) or to recommend to others any such
particular investment or other opportunity. Any Trustee may engage or be
interested in any financial or other transaction with the Depositor or any
Affiliate of the Depositor, or may act as depository for, trustee or agent for,
or act on any committee or body of holders of, securities or other obligations
of the Depositor or its Affiliates.

         SECTION 8.7 Corporate Property Trustee Required; Eligibility of
Trustees.

         (a) There shall at all times be a Property Trustee hereunder with
respect to the Trust Securities. The Property Trustee shall be a Person that is
eligible pursuant to the Trust Indenture Act to act as such and has a combined
capital and surplus of at least $50,000,000. If any such Person publishes
reports of condition at least annually, pursuant to law or to the requirements
of its supervising or examining authority, then for the purposes of this
Section, the combined capital and surplus of such Person shall be deemed to be
its combined capital and surplus as set forth in its most recent report of
condition so published. If at any time the Property Trustee with respect to the
Trust Securities shall cease to be eligible in accordance with the provisions of
this Section, it shall resign immediately in the manner and with the effect
hereinafter specified in this Article.
<PAGE>   49
                                                                              42



         (b) There shall at all times be one or more Administrative Trustees
hereunder with respect to the Trust Securities. Each Administrative Trustee
shall be either a natural person who is at least 21 years of age or a legal
entity that shall act through one or more persons authorized to bind that
entity.

         (c) There shall at all times be a Delaware Trustee with respect to the
Trust Securities. The Delaware Trustee shall either be (i) a natural person who
is at least 21 years of age and a resident of the State of Delaware or (ii) a
legal entity with its principal place of business in the State of Delaware and
that otherwise meets the requirements of applicable Delaware law that shall act
through one or more persons authorized to bind such entity.

         SECTION 8.8  Conflicting Interests.

         If the Property Trustee has or shall acquire a conflicting interest
within the meaning of the Trust Indenture Act, the Property Trustee shall either
eliminate such interest or resign, to the extent and in the manner provided by,
and subject to the provisions of, the Trust Indenture Act and this Trust
Agreement.

         SECTION 8.9  Co-Trustees and Separate Trustee.

         Unless an Event of Default shall have occurred and be continuing, at
any time or times, for the purpose of meeting the legal requirements of the
Trust Indenture Act or of any jurisdiction in which any part of the Trust
Property may at the time be located, the Depositor and the Administrative
Trustees, by agreed action of the majority of such Trustees, shall have power to
appoint, and upon the written request of the Administrative Trustees, the
Depositor shall for such purpose join with the Administrative Trustees in the
execution, delivery, and performance of all instruments and agreements necessary
or proper to appoint, one or more Persons approved by the Property Trustee
either to act as co-trustee, jointly with the Property Trustee, of all or any
part of such Trust Property, or to the extent required by law to act as separate
trustee of any such property, in either case with such powers as may be provided
in the instrument of appointment, and to vest in such Person or Persons in the
capacity aforesaid, any property, title, right or power deemed necessary or
desirable, subject to the other provisions of this Section. If the Depositor
does not join in such appointment within 15 days after the receipt by it of a
request so to do, or in case a Debenture Event of Default has occurred and is
continuing, the Property Trustee alone shall have power to make such
appointment. Any co-trustee or separate trustee appointed pursuant to this
Section shall either be (i) a natural person who is at least 21 years of age and
a resident of the United States or (ii) a legal entity with its principal place
of business in the United States that shall act through one or more persons
authorized to bind such entity.

         Should any written instrument from the Depositor be required by any
co-trustee or separate trustee so appointed for more fully confirming to such
co-trustee or separate trustee such property, title, right, or power, any and
all such instruments shall, on request, be executed, acknowledged and delivered
by the Depositor.
<PAGE>   50
                                                                              43



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

         (a) The Trust Securities shall be executed and delivered and all
rights, powers, duties, and obligations hereunder in respect of the custody of
securities, cash and other personal property held by, or required to be
deposited or pledged with, the Trustees specified hereunder shall be exercised
solely by such Trustees and not by such co-trustee or separate trustee.

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

         (c) The Property Trustee at any time, by an instrument in writing
executed by it, with the written concurrence of the Depositor, may accept the
resignation of or remove any co-trustee or separate trustee appointed under this
Section, and, in case a Debenture Event of Default has occurred and is
continuing, the Property Trustee shall have power to accept the resignation of,
or remove, any such co-trustee or separate trustee without the concurrence of
the Depositor. Upon the written request of the Property Trustee, the Depositor
shall join with the Property Trustee in the execution, delivery and performance
of all instruments and agreements necessary or proper to effectuate such
resignation or removal. A successor to any co-trustee or separate trustee so
resigned or removed may be appointed in the manner provided in this Section.

         (d) No co-trustee or separate trustee hereunder shall be personally
liable by reason of any act or omission of the Property Trustee or any other
trustee hereunder.

         (e) The Property Trustee shall not be liable by reason of any act of a
co-trustee or separate trustee.

         (f) Any Act of Holders delivered to the Property Trustee shall be
deemed to have been delivered to each such co-trustee and separate trustee.

         SECTION 8.10  Resignation and Removal; Appointment of Successor.

         No resignation or removal of any Trustee (the "Relevant Trustee") and
no appointment of a successor Trustee pursuant to this Article shall become
effective until the acceptance of appointment by the successor Trustee in
accordance with the applicable requirements of Section 8.11.
<PAGE>   51
                                                                              44



         Subject to the immediately preceding paragraph, the Relevant Trustee
may resign at any time by giving written notice thereof to the Common
Securityholders. If the instrument of acceptance by the successor Trustee
required by Section 8.11 shall not have been delivered to the Relevant Trustee
within 30 days after the giving of such notice of resignation, the Relevant
Trustee may petition, at the expense of the Trust, any court of competent
jurisdiction for the appointment of a successor Relevant Trustee.

         Unless a Debenture Event of Default shall have occurred and be
continuing, any Trustee may be removed at any time by Act of the Common
Securityholder. If a Debenture Event of Default shall have occurred and be
continuing, the Property Trustee or the Delaware Trustee, or both of them, may
be removed at such time by Act of the Holders of a majority in Liquidation
Amount of the Capital Securities, delivered to the Relevant Trustee (in its
individual capacity and on behalf of the Trust). An Administrative Trustee may
be removed by the Common Securityholder at any time. If the instrument of
acceptance by the successor Trustee required by Section 8.11 shall not have been
delivered to the Relevant Trustee within 30 days after such removal, the
Relevant Trustee may petition, at the expense of the Trust, any court of
competent jurisdiction for the appointment of a successor Relevant Trustee.

         If any Trustee shall resign, be removed or become incapable of acting
as Trustee, or if a vacancy shall occur in the office of any Trustee for any
cause, at a time when no Debenture Event of Default shall have occurred and be
continuing, the Common Securityholder, by Act of the Common Securityholder
delivered to the retiring Trustee, shall promptly appoint a successor Trustee or
Trustees, and the retiring Trustee shall comply with the applicable requirements
of Section 8.11. If the Property Trustee or the Delaware Trustee shall resign,
be removed or become incapable of continuing to act as the Property Trustee or
the Delaware Trustee, as the case may be, at a time when a Debenture Event of
Default shall have occurred and be continuing, the Capital Securityholders, by
Act of the Securityholders of a majority in Liquidation Amount of the Capital
Securities then Outstanding delivered to the retiring Relevant Trustee, shall
promptly appoint a successor Relevant Trustee or Trustees, and such successor
Trustee shall comply with the applicable requirements of Section 8.11. If an
Administrative Trustee shall resign, be removed or become incapable of acting as
Administrative Trustee, at a time when a Debenture Event of Default shall have
occurred and be continuing, the Common Securityholder by Act of the Common
Securityholder delivered to the Administrative Trustee shall promptly appoint a
successor Administrative Trustee or Administrative Trustees and such successor
Administrative Trustee or Trustees shall comply with the applicable requirements
of Section 8.11. If no successor Relevant Trustee shall have been so appointed
by the Common Securityholder or the Capital Securityholders and accepted
appointment in the manner required by Section 8.11, any Securityholder who has
been a Securityholder of Trust Securities for at least six months may, on behalf
of himself and all others similarly situated, petition any court of competent
jurisdiction for the appointment of a successor Relevant Trustee.
<PAGE>   52
                                                                              45



         The Property Trustee shall give notice of each resignation and each
removal of a Trustee and each appointment of a successor Trustee to all
Securityholders in the manner provided in Section 10.9 and shall give notice to
the Depositor. Each notice shall include the name of the successor Relevant
Trustee and the address of its Corporate Trust Office if it is the Property
Trustee.

         Notwithstanding the foregoing or any other provision of this Trust
Agreement, in the event any Administrative Trustee or a Delaware Trustee who is
a natural person dies or becomes, in the opinion of the Depositor, incompetent
or incapacitated, the vacancy created by such death, incompetence or incapacity
may be filled by (a) the unanimous act of the remaining Administrative Trustees
if there are at least two of them or (b) otherwise by the Depositor (with the
successor in each case being a Person who satisfies the eligibility requirement
for Administrative Trustees or Delaware Trustee, as the case may be, set forth
in Section 8.7).

         SECTION 8.11  Acceptance of Appointment by Successor.

         In case of the appointment hereunder of a successor Relevant Trustee,
the retiring Relevant Trustee and each successor Relevant Trustee with respect
to the Trust Securities shall execute and deliver an amendment hereto wherein
each successor Relevant Trustee shall accept such appointment and which (a)
shall contain such provisions as shall be necessary or desirable to transfer and
confirm to, and to vest in, each successor Relevant Trustee all the rights,
powers, trusts and duties of the retiring Relevant Trustee with respect to the
Trust Securities and the Trust and (b) shall add to or change any of the
provisions of this Trust Agreement as shall be necessary to provide for or
facilitate the administration of the Trust by more than one Relevant Trustee, it
being understood that nothing herein or in such amendment shall constitute such
Relevant Trustees co-trustees and upon the execution and delivery of such
amendment the resignation or removal of the retiring Relevant Trustee shall
become effective to the extent provided therein and each such successor Relevant
Trustee, without any further act, deed or conveyance, shall become vested with
all the rights, powers, trusts and duties of the retiring Relevant Trustee; but,
on written request of the Trust or any successor Relevant Trustee such retiring
Relevant Trustee shall, upon payment of its charges, duly assign, transfer and
deliver to such successor Relevant Trustee all Trust Property, all proceeds
thereof and money held by such retiring Relevant Trustee hereunder with respect
to the Trust Securities and the Trust.

         Upon written request of any such successor Relevant Trustee, the Trust
shall execute any and all instruments for more fully and certainly vesting in
and confirming to such successor Relevant Trustee all such rights, powers and
trusts referred to in the preceding paragraph.

         No successor Relevant Trustee shall accept its appointment unless at
the time of such acceptance such successor Relevant Trustee shall be qualified
and eligible under this Article.
<PAGE>   53
                                                                              46


         SECTION 8.12 Merger, Conversion, Consolidation or Succession to
Business.

         Any Person into which the Property Trustee or the Delaware Trustee may
be merged or converted or with which it may be consolidated, or any Person
resulting from any merger, conversion or consolidation to which such Relevant
Trustee shall be a party, or any Person succeeding to all or substantially all
the corporate trust business of such Relevant Trustee, shall be the successor of
such Relevant Trustee hereunder, provided such Person shall be otherwise
qualified and eligible under this Article, without the execution or filing of
any paper or any further act on the part of any of the parties hereto.

         SECTION 8.13 Preferential Collection of Claims Against Depositor or
Trust.

         In case of the pendency of any receivership, insolvency, liquidation,
bankruptcy, reorganization, arrangement, adjustment, composition or other
similar judicial proceeding relative to the Trust or any other obligor upon the
Trust Securities or the property of the Trust or of such other obligor or their
creditors, the Property Trustee (irrespective of whether any Distributions on
the Trust Securities shall then be due and payable as therein expressed or by
declaration or otherwise and irrespective of whether the Property Trustee shall
have made any demand on the Trust for the payment of any past due Distributions)
shall be entitled and empowered, to the fullest extent permitted by law, by
intervention in such proceeding or otherwise:

         (a) to file and prove a claim for the whole amount of any Distributions
owing and unpaid in respect of the Trust Securities and to file such other
papers or documents as may be necessary or advisable in order to have the claims
of the Property Trustee (including any claim for the reasonable compensation,
expenses, disbursements and advances of the Property Trustee, its agents and
counsel) and of the Holders allowed in such judicial proceeding, and

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

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

         Nothing herein contained shall be deemed to authorize the Property
Trustee to authorize or consent to or accept or adopt on behalf of any Holder
any plan of reorganization, arrangement, adjustment or compensation affecting
the Trust Securities or the rights of any Holder thereof or to authorize the
Property Trustee to vote in respect of the claim of any Holder in any such
proceeding.

         SECTION 8.14  Reports by Property Trustee.

         (a) The Property Trustee shall transmit to Securityholders such reports
concerning the Property Trustee and its actions under this Trust Agreement as
may be required pursuant to the Trust Indenture Act at the times and in the
manner provided pursuant thereto. If required by Section 313(a) of the Trust
Indenture Act, the Property Trustee shall, within sixty days after each May 15
following the date of this Trust Agreement deliver to Securityholders a brief
report, dated as of such May 15, which complies with the provisions of such
Section 313(a).

         (b) A copy of each such report shall, at the time of such transmission
to Holders, be filed by the Property Trustee with each national stock exchange,
the Nasdaq National Market or such other interdealer quotation system or
self-regulatory organization upon which the Trust Securities are listed or
traded, if any, with the Commission and with the Depositor. The Depositor will
promptly notify the Property Trustee of any such listing or trading.

         SECTION 8.15  Reports to the Property Trustee.

         The Depositor and the Administrative Trustees on behalf of the Trust
shall provide to the Property Trustee such documents, reports and information as
required by Section 314 of the Trust Indenture Act (if any) and the compliance
certificate required by Section 314(a) of the Trust Indenture Act in the form,
in the manner and at the times required by Section 314 of the Trust Indenture
Act. Delivery of such reports, information and documents to the Property Trustee
is for informational purposes only and the Property Trustee's receipt of such
shall not constitute constructive notice of any information contained therein or
determinable from information contained therein, including the Trust's
compliance with any of its covenants hereunder (as to which the Property Trustee
is entitled to rely exclusively on Officers' Certificates).

         SECTION 8.16  Evidence of Compliance with Conditions Precedent.

         Each of the Depositor and the Administrative Trustees on behalf of the
Trust shall provide to the Property Trustee such evidence of compliance with any
conditions precedent, if any, provided for in this Trust Agreement that relate
to any of the matters set forth in Section 314(c) of the Trust Indenture Act.
Any certificate or opinion required to be given by an officer pursuant to
Section 314(c)(1) of the Trust Indenture Act shall be given in the form of an
Officers' Certificate.

         SECTION 8.17  Number of Trustees.

         (a) The number of Trustees shall be four, provided that the Holder of
all of the Common Securities by written instrument may increase or decrease the
number of Administrative Trustees. The Property Trustee and the Delaware Trustee
may be the same Person.

         (b) If a Trustee ceases to hold office for any reason and the number of
Administrative Trustees is not reduced pursuant to Section 8.17(a), or if the
number of Trustees is increased pursuant to Section 8.17(a), a vacancy shall
occur. The vacancy shall be filled with a Trustee appointed in accordance with
Section 8.10.

         (c) The death, resignation, retirement, removal, bankruptcy,
incompetence or incapacity to perform the duties of a Trustee shall not operate
to dissolve, terminate or annul the Trust. Whenever a vacancy in the number of
Administrative Trustees shall occur, until such vacancy is filled by the
appointment of an Administrative Trustee in accordance with Section 8.10, the
Administrative Trustees in office, regardless of their number (and
notwithstanding any other provision of this Agreement), shall have all the
powers granted to the Administrative Trustees and shall discharge all the duties
imposed upon the Administrative Trustees by this Trust Agreement.

         SECTION 8.18  Delegation of Power.

         (a) Any Administrative Trustee may, by power of attorney consistent
with applicable law, delegate to any other natural person over the age of 21 his
or her power for the purpose of executing any documents contemplated in Section
2.7(a), including any registration statement or amendment thereto filed with the
Commission, or making any other governmental filing; and

         (b) The Administrative Trustees shall have power to delegate from time
to time to such of their number or to the Depositor the doing of such things and
the execution of such instruments either in the name of the Trust or the names
of the Administrative Trustees or otherwise as the Administrative Trustees may
deem expedient, to the extent such delegation is not prohibited by applicable
law or contrary to the provisions of this Trust Agreement, as set forth herein.

         SECTION 9.1  Termination Upon Expiration Date.

         Unless earlier terminated, the Trust shall automatically terminate on
December 6, 2051 (the "Expiration Date"), following the distribution of the
Trust Property in accordance with Section 9.4.

         SECTION 9.2  Early Termination.

         The first to occur of any of the following events is an "Early
Termination Event":

         (a) the occurrence of a Bankruptcy Event in respect of, or the
dissolution or liquidation of, the Holder of the Common Securities;

         (b) the written direction to the Property Trustee from the Depositor at
any time to terminate the Trust and, after satisfaction of liabilities to
creditors of the Trust as provided by applicable law, distribute Debentures to
Securityholders in exchange for the Capital Securities (which direction is
optional and wholly within the discretion of the Depositor);

         (c) the redemption of all of the Capital Securities in connection with
the redemption or maturity of all of the Debentures; and

         (d) the entry of an order for dissolution of the Trust by a court of
competent jurisdiction.

         SECTION 9.3  Termination.

         The respective obligations and responsibilities of the Trustees and the
Trust created and continued hereby shall terminate upon the latest to occur of
the following: (a) the distribution by the Property Trustee to Securityholders
upon the liquidation of the Trust pursuant to Section 9.4, or upon the
redemption of all of the Trust Securities pursuant to Section 4.2, of all
amounts required to be distributed hereunder upon the final payment of the Trust
Securities; (b) the payment of any expenses owed by the Trust; and (c) the
discharge of all administrative duties of the Administrative Trustees, including
the performance of any tax reporting obligations with respect to the Trust or
the Securityholders.

         SECTION 9.4  Liquidation.

         (a) If an Early Termination Event specified in clause (a), (b) or (d)
of Section 9.2 occurs or upon the Expiration Date, the Trust shall be liquidated
by the Trustees as
<PAGE>   57
                                                                              50



expeditiously as the Trustees determine to be possible by distributing, after
satisfaction or the making of reasonable provisions for the payment of
liabilities to creditors of the Trust as provided by applicable law, to each
Securityholder a Like Amount of Debentures, subject to Section 9.4(d). Notice of
liquidation shall be given by the Property Trustee by first-class mail, postage
prepaid mailed not later than 30 nor more than 60 days prior to the Liquidation
Date to each Holder of Trust Securities at such Holder's address appearing in
the Securities Register. All notices of liquidation shall:

                         (i)   state the CUSIP Number of the Trust Securities;

                        (ii)   state the Liquidation Date;

                       (iii)   state that from and after the Liquidation Date,
         the Trust Securities will no longer be deemed to be Outstanding and any
         Trust Securities Certificates not surrendered for exchange will be
         deemed to represent a Like Amount of Debentures; and 

                        (iv)   provide such information with respect to the
         mechanics by which Holders may exchange Trust Securities Certificates
         for Debentures, or if Section 9.4(d) applies receive a Liquidation
         Distribution, as the Administrative Trustees or the Property Trustee
         shall deem appropriate.

         (b) Except where Section 9.2(c) or 9.4(d) applies, in order to effect
the liquidation of the Trust and distribution of the Debentures to
Securityholders, the Property Trustee shall establish a record date for such
distribution (which shall be not more than 45 days prior to the Liquidation
Date) and, either itself acting as exchange agent or through the appointment of
a separate exchange agent, shall establish such procedures as it shall deem
appropriate to effect the distribution of Debentures in exchange for the
Outstanding Trust Securities Certificates.

         (c) Except where Section 9.2(c) or 9.4(d) applies, after the
Liquidation Date, (i) the Trust Securities will no longer be deemed to be
Outstanding, (ii) certificates representing a Like Amount of Debentures will be
issued to Holders of Trust Securities Certificates, upon surrender of such
certificates to the Administrative Trustees or their agent for exchange, (iii)
the Depositor shall use its best efforts to have the Debentures listed on the
New York Stock Exchange or on such other exchange, interdealer quotation system
or self-regulatory organization as the Capital Securities are then listed or
traded, (iv) any Trust Securities Certificates not so surrendered for exchange
will be deemed to represent a Like Amount of Debentures, accruing interest at
the rate provided for in the Debentures from the last Distribution Date on which
a Distribution was made on such Trust Securities Certificates until such
certificates are so surrendered (and until such certificates are so surrendered,
no payments of interest or principal will be made to Holders of Trust Securities
Certificates with respect to such Debentures) and (v) all rights of
Securityholders holding Trust Securities will 
<PAGE>   58
                                                                              51



cease, except the right of such Securityholders to receive Debentures upon
surrender of Trust Securities Certificates.

         (d) In the event that, notwithstanding the other provisions of this
Section 9.4, whether because of an order for dissolution entered by a court of
competent jurisdiction or otherwise, distribution of the Debentures in the
manner provided herein is determined by the Property Trustee not to be
practical, the Trust Property shall be liquidated, and the Trust shall be
dissolved, wound-up or terminated, by the Property Trustee. In such event, on
the date of the dissolution, winding-up or other termination of the Trust,
Securityholders will be entitled to receive out of the assets of the Trust
available for distribution to Securityholders, after satisfaction of liabilities
to creditors of the Trust as provided by applicable law, an amount equal to the
Liquidation Amount per Trust Security plus accumulated and unpaid Distributions
thereon to the date of payment (such amount being the "Liquidation
Distribution"). If, upon any such dissolution, winding up or termination, the
Liquidation Distribution can be paid only in part because the Trust has
insufficient assets available to pay in full the aggregate Liquidation
Distribution, then, subject to the next succeeding sentence, the amounts payable
by the Trust on the Trust Securities shall be paid on a pro rata basis (based
upon Liquidation Amounts). The Holder of the Common Securities will be entitled
to receive Liquidation Distributions upon any such dissolution, winding-up or
termination pro rata (determined as aforesaid) with Holders of Capital
Securities, except that, if a Debenture Event of Default has occurred and is
continuing, the Capital Securities shall have a priority over the Common
Securities.

         SECTION 9.5 Mergers, Consolidations, Amalgamations or Replacements of
the Trust.

         The Trust may not merge with or into, consolidate, amalgamate, or be
replaced by, or convey, transfer or lease its properties and assets
substantially as an entirety to any corporation or other Person, except pursuant
to this Article IX. At the request of the Depositor, with the consent of the
Administrative Trustees and without the consent of the Holders of the Capital
Securities, the Property Trustee or the Delaware Trustee, the Trust may merge
with or into, consolidate, amalgamate, or be replaced by or convey, transfer or
lease its properties and assets substantially as an entirety to a trust
organized as such under the laws of any State; provided, that (i) such successor
entity either (a) expressly assumes all of the obligations of the Trust with
respect to the Capital Securities or (b) substitutes for the Capital Securities
other securities having substantially the same terms as the Capital Securities
(the "Successor Securities") so long as the Successor Securities rank the same
as the Capital Securities rank in priority with respect to distributions and
payments upon liquidation, redemption and otherwise, (ii) the Depositor
expressly appoints a trustee of such successor entity possessing the same powers
and duties as the Property Trustee as the holder of the Debentures, (iii) the
Successor Securities are listed or traded, or any Successor Securities will be
listed upon notification of issuance, on any national securities exchange or
other organization on which the Capital Securities are then listed or traded, if
any, (iv) such merger, consolidation, amalgamation, replacement, conveyance,
transfer or lease does not cause the Capital Securities (including any Successor
Securities) to be downgraded by any 
<PAGE>   59
                                                                              52



nationally recognized statistical rating organization, (v) such merger,
consolidation, amalgamation, replacement, conveyance, transfer or lease does not
adversely affect the rights, preferences and privileges of the holders of the
Capital Securities (including any Successor Securities) in any material respect,
(vi) such successor entity has a purpose identical to that of the Trust, (vii)
prior to such merger, consolidation, amalgamation, replacement, conveyance,
transfer or lease, the Depositor has received an Opinion of Counsel to the
effect that (a) such merger, consolidation, amalgamation, replacement,
conveyance, transfer or lease does not adversely affect the rights, preferences
and privileges of the holders of the Capital Securities (including any Successor
Securities) in any material respect, and (b) following such merger,
consolidation, amalgamation, replacement, conveyance, transfer or lease, neither
the Trust nor such successor entity will be required to register as an
investment company under the 1940 Act and (viii) the Depositor owns all of the
common securities of such successor entity and guarantees the obligations of
such successor entity under the Successor Securities at least to the extent
provided by the Guarantee. Notwithstanding the foregoing, the Trust shall not,
except with the consent of Holders of 100% in Liquidation Amount of the Capital
Securities, consolidate, amalgamate, merge with or into, or be replaced by or
convey, transfer or lease its properties and assets substantially as an entirety
to any other Person or permit any other Person to consolidate, amalgamate, merge
with or into, or replace it if such consolidation, amalgamation, merger,
replacement, conveyance, transfer or lease would cause the Trust or the
successor entity to be taxable as a corporation or to be classified as other
than a grantor trust for United States federal income tax purposes.

                            MISCELLANEOUS PROVISIONS

         SECTION 10.1  Limitation of Rights of Securityholders.

         The death, incapacity, liquidation, dissolution, termination or
bankruptcy of any Person having an interest, beneficial or otherwise, in Trust
Securities shall not operate to terminate this Trust Agreement, nor entitle the
legal representatives or heirs of such Person or any Securityholder for such
Person, to claim an accounting, take any action or bring any proceeding in any
court for a partition or winding up of the arrangements contemplated hereby, nor
otherwise affect the rights, obligations and liabilities of the parties hereto
or any of them.

         SECTION 10.2  Liability of the Common Securityholder.

         The Holder of the Common Securities shall be liable for all of the
debts and obligations of the Trust (other than with respect to the Securities)
to the extent not satisfied out of the Trust's assets.

         SECTION 10.3   Amendment.

         (a) This Trust Agreement may be amended from time to time by the
Property Trustee, the Administrative Trustees and the Depositor, without the
consent of any Securityholders, (i) to cure any ambiguity, correct or supplement
any provision herein which may be inconsistent with any other provision herein,
or to make any other provisions with respect to matters or questions arising
under this Trust Agreement, which shall not be inconsistent with the other
provisions of this Trust Agreement, or (ii) to modify, eliminate or add to any
provisions of this Trust Agreement to such extent as shall be necessary to
ensure that the Trust will be classified for United States federal income tax
purposes as a grantor trust and not be taxable as a corporation at all times
that any Trust Securities are outstanding or to ensure that the Trust will not
be required to register as an investment company under the 1940 Act; provided,
however, that in the case of clause (i) or clause (ii), such action shall not
adversely affect in any material respect the interests of any Securityholder,
and any amendments of this Trust Agreement shall become effective when notice
thereof is given to the Securityholders.

         (b) Except as provided in Section 10.3(c) hereof, any provision of this
Trust Agreement may be amended by the Trustees and the Depositor with (i) the
consent of Trust Securityholders representing not less than a majority (based
upon Liquidation Amounts) of the Trust Securities then Outstanding and (ii)
receipt by the Trustees of an Opinion of Counsel to the effect that such
amendment or the exercise of any power granted to the Trustees in accordance
with such amendment will not affect the Trust's exemption from status of an
investment company under the 1940 Act or the Trust's status as a grantor trust
for United States federal income tax purposes and will not result in the Trust
being taxable as a corporation for United States federal income tax purposes.

         (c) In addition to and notwithstanding any other provision in this
Trust Agreement, without the consent of each affected Securityholder (such
consent being obtained in accordance with Section 6.3 or 6.6 hereof), this Trust
Agreement may not be amended to (i) change the amount or timing of any
Distribution on the Trust Securities or otherwise adversely affect the amount of
any Distribution required to be made in respect of the Trust Securities as of a
specified date or (ii) restrict the right of a Securityholder to institute suit
for the enforcement of any such payment on or after such date; notwithstanding
any other provision herein, without the unanimous consent of the Securityholders
(such consent being obtained in accordance with Section 6.3 or 6.6 hereof), this
paragraph (c) of this Section 10.3 may not be amended.

         (d) Notwithstanding any other provisions of this Trust Agreement, no
Trustee shall enter into or consent to any amendment to this Trust Agreement
which would cause the Trust to (i) fail or cease to qualify for the exemption
from status of an investment company under the 1940 Act, (ii) fail or cease to
be classified as a grantor trust for United States federal income tax purposes
or (iii) be taxable as a corporation for United States federal income tax
purposes.

         (e) Notwithstanding anything in this Trust Agreement to the contrary,
without the consent of the Depositor, this Trust Agreement may not be amended in
a manner which imposes any additional obligation on the Depositor.

         (f) In the event that any amendment to this Trust Agreement is made,
the Administrative Trustees shall promptly provide to the Depositor a copy of
such amendment.

         (g) Neither the Property Trustee nor the Delaware Trustee shall be
required to enter into any amendment to this Trust Agreement which affects its
own rights, duties or immunities under this Trust Agreement. The Property
Trustee shall be entitled to receive an Opinion of Counsel and an Officers'
Certificate stating that any amendment to this Trust Agreement is in compliance
with this Trust Agreement.

         SECTION 10.4  Separability.

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

         SECTION 10.5  Governing Law.

PRINCIPLES).

         SECTION 10.6  Payments Due on Non-Business Day.

         If the date fixed for any payment on any Trust Security shall be a day
that is not a Business Day, then such payment need not be made on such date but
may be made on the next succeeding day that is a Business Day (except as
otherwise provided in Sections 4.1(a) and 4.2(d)), with the same force and
effect as though made on the date fixed for such payment, and no interest shall
accrue thereon for the period after such date.

         SECTION 10.7  Successors.

         This Trust Agreement shall be binding upon and shall inure to the
benefit of any successor to the Depositor, the Trust or the Relevant Trustee,
including any successor by operation of law. Except in connection with a

writing to perform the Depositor's obligations hereunder, the Depositor shall
not assign its obligations hereunder.

         Any notice, demand or other communication which by any provision of

         SECTION 10.10  Agreement Not to Petition.

Securityholders that, until at least one year and one day after the Trust has
been terminated in accordance with Article IX, they shall not file, or join in
the filing of, a petition against the Trust under any bankruptcy, insolvency,
reorganization or other similar law (including, without limitation, the United
States Bankruptcy Code) (collectively, "Bankruptcy Laws") or otherwise join in

<PAGE>   63
                                                                              56



Depositor, it shall file an answer with the bankruptcy court or otherwise
properly contest the filing of such petition by the Depositor against the Trust
or the commencement of such action and raise the defense that the Depositor has
agreed in writing not to take such action and should be stopped and precluded
therefrom and such other defenses, if any, as counsel for the Trustee or the
Trust may assert. The provisions of this Section 10.10 shall survive the
termination of this Trust Agreement.

         SECTION 10.11  Trust Indenture Act; Conflict with Trust Indenture Act.

         (a) This Trust Agreement is subject to the provisions of the Trust
Indenture Act that are required or deemed to be part of this Trust Agreement and

         (b) The Property Trustee shall be the only Trustee which is a trustee
for the purposes of the Trust Indenture Act.

         (c) If any provision hereof limits, qualifies or conflicts with another
provision hereof which is required or deemed to be included in this Trust
Agreement by any of the provisions of the Trust Indenture Act, such required or
deemed provision shall control. If any provision of this Trust Agreement
modifies or excludes any provision of the Trust Indenture Act which may be so
modified or excluded, the latter provision shall be deemed to apply to this
Trust Agreement as so modified or excluded, as the case may be.

         (d) The application of the Trust Indenture Act to this Trust Agreement
shall not affect the nature of the Trust Securities as equity securities
representing undivided beneficial interests in the assets of the Trust.

         SECTION 10.12 Acceptance of Terms of Trust Agreement, Guarantee and
Indenture.

         THE RECEIPT AND ACCEPTANCE OF A TRUST SECURITY OR ANY INTEREST THEREIN
BY OR ON BEHALF OF A SECURITYHOLDER OR ANY BENEFICIAL OWNER, WITHOUT ANY
SIGNATURE OR FURTHER MANIFESTATION OF ASSENT, SHALL CONSTITUTE THE UNCONDITIONAL
ACCEPTANCE BY THE SECURITYHOLDER AND ALL OTHERS HAVING A BENEFICIAL INTEREST IN
SUCH TRUST SECURITY OF ALL THE TERMS AND PROVISIONS OF THIS TRUST AGREEMENT AND
AGREEMENT TO THE SUBORDINATION PROVISIONS AND OTHER TERMS OF THE GUARANTEE AND
THE INDENTURE, AND SHALL CONSTITUTE THE AGREEMENT OF THE TRUST, SUCH

         SECTION 10.13  Counterparts.

Attention:  General Counsel's Office

         Re:      First Tennessee Capital I
                  8.07% Capital Securities, Series A
                  CUSIP

Ladies and Gentlemen:

         The purpose of this letter is to set forth certain matters relating to
the issuance and deposit with The Depository Trust Company ("DTC") of the
book-entry-only portion of the 8.07% Capital Securities, Series A (the "Capital
Securities"), of First Tennessee Capital I, a statutory business trust formed
under the laws of the State of Delaware (the "Issuer"), governed by the Amended
and Restated Trust Agreement, dated as of December 30, 1996, between First
Tennessee National Corporation ("the Corporation"), as Depositor, The Bank of
New York, as Property Trustee, and The Bank of New York (Delaware), as Delaware
Trustee. The payment of distributions on the Capital Securities and payments due
upon liquidation of the Issuer or redemption of the Capital Securities, to the
extent the Issuer has funds available for the payment thereof, are guaranteed by
the Corporation to the extent set forth in a Guarantee Agreement, dated as of
December 30, 1996, between the Corporation and The Bank of New York, as
Guarantee Trustee with respect to the Capital Securities. The Corporation and
the Issuer propose to sell the Capital Securities to certain Underwriters (the
"Underwriters") pursuant to an Underwriting Agreement, dated as of December 30,
1996, by and among the Underwriters, the Issuer and the Corporation, and the
Underwriters wish to take delivery of the Capital Securities through DTC. The
Bank of New York is 

                                       C-1
<PAGE>   75
acting as transfer agent and registrar with respect to the Capital Securities
(the "Transfer Agent and Registrar").

         To induce DTC to accept the Capital Securities as eligible for deposit
at DTC, and to act in accordance with DTC's rules with respect to the Capital
Securities, the Issuer and the Transfer Agent and Registrar make the following
representations to DTC:

         1. Prior to the closing of the sale of the Capital Securities to the
Underwriters on January 6, 1997, there shall be deposited with, or held by the
Transfer Agent and Registrar as custodian for, DTC one or more global
certificates (individually and collectively, the "Global Certificate")
registered in the name of DTC's nominee, Cede & Co., representing an aggregate
of 100,000 Capital Securities and bearing the following legend:

    Unless this certificate is presented by an authorized representative of The
    Depository Trust Company, a New York corporation ("DTC"), to Issuer or its
    agent for registration of transfer, exchange, or payment, and any
    certificate issued is registered in the name of Cede & Co. or in such other
    name as is requested by an authorized representative of DTC (and any payment
    is made to Cede & Co. or to such other entity as is requested by an
    authorized representative of DTC), ANY TRANSFER, PLEDGE, OR OTHER USE HEREOF
    FOR VALUE OR OTHERWISE BY OR TO ANY PERSON IS WRONGFUL inasmuch as the
    registered owner hereof, Cede & Co., has an interest herein.

         2. The Amended and Restated Trust Agreement of the Issuer provides for
the voting by holders (with no provision for revocation of consents or votes by
subsequent holders) of the Capital Securities under certain limited
circumstances. The Issuer shall establish a record date for such purposes and
shall, to the extent possible, give DTC notice of such record date not less than
15 calendar days in advance of such record date.

         3. In the event of a stock split, conversion, recapitalization,
reorganization or any other similar transaction resulting in the cancellation of
all or any part of the Capital Securities outstanding, the Issuer or the
Transfer Agent and Registrar shall send DTC a notice of such event as soon as
possible, but at least 5 business days prior to the effective date of such
event.

         4. In the event of any distribution on, or an offering or issuance of
rights with respect to, the Capital Securities outstanding, the Issuer or the
Transfer Agent and Registrar shall send DTC a notice specifying: (a) the amount
of and conditions, if any, applicable to the payment of any such distribution or
any such offering or issuance of rights; (b) any applicable expiration or
deadline date, or any date by which any action on the part of the holders of
Capital Securities is required; and (c) the date any required notice is to be
mailed by or on behalf of the Issuer to holders of Capital Securities or
published by or on behalf of the Issuer (whether by mail or publication, the
"Publication Date"). Such notice shall be sent to DTC by a secure means (e.g.,
legible telecopy, registered or certified mail, overnight 

                                       C-2
<PAGE>   76
delivery) in a timely manner designed to assure that such notice is in DTC's
possession no later than the close of business on the business day before the
Publication Date. The Issuer or the Transfer Agent and Registrar will forward
such notice either in a separate secure transmission for each CUSIP number or in
a secure transmission of multiple CUSIP numbers (if applicable) that includes a
manifest or list of each CUSIP number submitted in that transmission. (The party
sending such notice shall have a method to verify subsequently the use of such
means and the timeliness of such notice.) The Publication Date shall be not less
than 30 calendar days nor more than 60 calendar days prior to the payment of any
such distribution or any such offering or issuance of rights with respect to the
Capital Securities. After establishing the amount of payment to be made on the
Capital Securities, the Issuer or the Transfer Agent and Registrar will notify
DTC's Dividend Department of such payment 5 business days prior to payment date.
Notices to DTC's Dividend Department by telecopy shall be sent to (212)
709-1723. Such notices by mail or by any other means shall be sent to:

                          New York, New York 10004-2695

         The Issuer or the Transfer Agent and Registrar shall confirm DTC's
receipt of such telecopy by telephoning the Dividend Department at (212)
709-1270.

         5. In the event of a redemption by the Issuer of the Capital
Securities, notice specifying the terms of the redemption and the Publication
Date of such notice shall be sent by the Issuer or the Transfer Agent and
Registrar to DTC not less than 30 calendar days prior to such event by a secure
means in the manner set forth in paragraph 4. Such redemption notice shall be
sent to DTC's Call Notification Department at (516) 227-4164 or (516) 227-4190,
and receipt of such notice shall be confirmed by telephoning (516) 227-4070.

                          Garden City, New York 11530-4719

         6. In the event of any invitation to tender the Capital Securities,
notice specifying the terms of the tender and the Publication Date of such
notice shall be sent by the Issuer or the Transfer Agent and Registrar to DTC by
a secure means and in a timely manner as described in paragraph 4. Notices to

         7. All notices and payment advices sent to DTC shall contain the CUSIP
number or numbers of the Capital Securities and the accompanying designation of
the Capital Securities, which, as of the date of this letter, is "First
Tennessee Capital I, 8.07% Capital Securities, Series A".

         8. Distribution payments or other cash payments with respect to the
Capital Securities shall be governed by DTC's current Principal and Income
Payments Rider, a copy of which is attached hereto as Annex I. For purposes of
this letter, the term "Agent" used in Annex I shall be deemed to refer to The
Bank of New York or any successor Property Trustee under the Amended and
Restated Trust Agreement.

         9. DTC may direct the Issuer and the Transfer Agent and Registrar to
use any other telecopy number or address of DTC as the number or address to
which notices or payments may be sent.

         10. In the event of a conversion, redemption, or any other similar
transaction (e.g., tender made and accepted in response to the Issuer's or the
Transfer Agent and Registrar's invitation) necessitating a reduction in the
aggregate number of Capital Securities outstanding evidenced by the Global
Certificate, DTC, in its discretion: (a) may request the Issuer or the Transfer
Agent and Registrar to issue and countersign a new Global Certificate; or (b)
may make an appropriate notation on the Global Certificate indicating the date
and amount of such reduction.

         11. DTC may discontinue its services as a securities depositary with
respect to the Capital Securities at any time by giving reasonable prior written
notice to the Issuer and the Transfer Agent and Registrar (at which time DTC
will confirm with the Issuer or the Transfer Agent and Registrar the aggregate
number of Capital Securities deposited with it) and discharging its
responsibilities with respect thereto under applicable law. Under such
circumstances, the Issuer may determine to make alternative arrangements for
book-entry settlement for the Capital Securities, make available one or more
separate global certificates evidencing Capital Securities to any Participant
having Capital Securities credited to its DTC account, or issue definitive
Capital Securities to the beneficial holders thereof, and in any such case, DTC
agrees to cooperate fully with the Issuer and the Transfer Agent and Registrar
and to return the Global Certificate, duly endorsed for transfer as directed by
the

Issuer or the Transfer Agent and Registrar, together with any other documents of
transfer reasonably requested by the Issuer or the Transfer Agent and Registrar.

         12. In the event that the Issuer determines that beneficial owners of
Capital Securities shall be able to obtain definitive Capital Securities, the
Issuer or the Transfer Agent and Registrar shall notify DTC of the availability
of certificates. In such event, the Issuer or the Transfer Agent and Registrar
shall issue, transfer and exchange certificates in appropriate amounts, as
required by DTC and others, and DTC agrees to cooperate fully with the Issuer
and the Transfer Agent and Registrar and to return the Global Certificate, duly
endorsed for transfer as directed by the Issuer or the Transfer Agent and
Registrar, together with any other documents of transfer reasonably requested by
the Issuer or the Transfer Agent and Registrar.

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

Default and its consequences. Upon such waiver, any such Event of Default shall
cease to exist, and any Event of Default arising therefrom shall be deemed to

waiver shall extend to any subsequent or other default or Event of Default or
impair any right consequent therefrom.

         SECTION 2.7.   Event of Default; Notice.

         (a) The Guarantee Trustee shall, within 90 days after the occurrence
of an Event of Default, transmit by mail, first class postage prepaid, to the
Holders, notices of all Events of Default actually known to the Guarantee
Trustee, unless such defaults have been cured before the giving of such notice,

Payment, the Guarantee Trustee shall be protected in withholding such notice if

committee of the Board of Directors and/or Responsible Officers of the
Guarantee Trustee in good faith determines that the withholding of such notice
is in the interests of the Holders.

         (b) The Guarantee Trustee shall not be deemed to have knowledge of any

         SECTION 2.8.   Conflicting Interests.

         The Trust Agreement shall be deemed to be specifically described in
this Guarantee Agreement for the purposes of clause (i) of the first proviso
contained in Section 310(b) of the Trust Indenture Act.


       ARTICLE III.   POWERS, DUTIES AND RIGHTS OF THE GUARANTEE TRUSTEE

         SECTION 3.1.   Powers and Duties of the Guarantee Trustee.

         (a) This Guarantee Agreement shall be held by the Guarantee Trustee
for the benefit of the Holders, and the Guarantee Trustee shall not transfer
this Guarantee Agreement to any Person except a Holder exercising his or her
rights pursuant to Section 5.4(iv) or to a Successor Guarantee Trustee on
acceptance by such Successor Guarantee Trustee of its appointment to act as
Successor Guarantee Trustee. The right, title and interest of the Guarantee
Trustee shall automatically vest in any Successor Guarantee Trustee, upon
acceptance by such Successor Guarantee Trustee of its appointment hereunder,
and such vesting and cessation of title shall be effective whether or not
conveyancing documents have been executed and delivered pursuant to the
appointment of such Successor Guarantee Trustee.

         (b) If an Event of Default has occurred and is continuing, the
Guarantee Trustee shall enforce this Guarantee Agreement for the benefit of the
Holders.

         (c) The Guarantee Trustee, before the occurrence of any Event of
Default and after the curing of all Events of Default that may have occurred,
shall undertake to perform only such duties as are specifically set forth in
this Guarantee Agreement, and no implied covenants shall be read into this
Guarantee Agreement against the Guarantee Trustee. In case an Event of Default
has occurred (that has not been cured or waived pursuant to Section 2.6), the
Guarantee Trustee shall exercise such of the rights and powers vested in it by
this Guarantee Agreement, and use the same degree of care and skill in its
exercise thereof, as a prudent person would exercise or use under the
circumstances in the conduct of his or her own affairs.

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

                 (i) prior to the occurrence of any Event of Default and after
         the curing or waiving of all such Events of Default that may have
         occurred:

                 (A) the duties and obligations of the Guarantee Trustee shall
         be determined solely by the express provisions of this Guarantee
         Agreement, and the Guarantee Trustee shall not be liable, except for 
         the performance of such duties and obligations as are specifically set
         forth in this Guarantee Agreement; and
<PAGE>   11
                                                                               7




                 (B) in the absence of bad faith on the part of the Guarantee
         Trustee, the Guarantee Trustee may conclusively rely, as to the truth
         of the statements and the correctness of the opinions expressed
         therein, upon any certificates or opinions furnished to the Guarantee
         Trustee and conforming to the requirements of this Guarantee
         Agreement; but in the case of any such certificates or opinions that
         by any provision hereof or of the Trust Indenture Act are specifically
         required to be furnished to the Guarantee Trustee, the Guarantee
         Trustee shall be under a duty to examine the same to determine whether
         or not they conform to the requirements of this Guarantee Agreement;

                 (ii) the Guarantee Trustee shall not be liable for any error
         of judgment made in good faith by a Responsible Officer of the
         Guarantee Trustee, unless it shall be proved that the Guarantee
         Trustee was negligent in ascertaining the pertinent facts upon which
         such judgment was made;

                 (iii) the Guarantee Trustee shall not be liable with respect
         to any action taken or omitted to be taken by it in good faith in
         accordance with the direction of the Holders of not less than a
         Majority in aggregate Liquidation Amount of the Securities relating to
         the time, method and place of conducting any proceeding for any remedy
         available to the Guarantee Trustee, or exercising any trust or power
         conferred upon the Guarantee Trustee under this Guarantee Agreement;
         and

                 (iv) no provision of this Guarantee Agreement shall require
         the Guarantee Trustee to expend or risk its own funds or otherwise
         incur personal financial liability in the performance of any of its
         duties or in the exercise of any of its rights or powers, if the
         Guarantee Trustee shall have reasonable grounds for believing that the
         repayment of such funds or liability is not reasonably assured to it
         under the terms of this Guarantee Agreement or adequate indemnity
         against such risk or liability is not reasonably assured to it.

         SECTION 3.2.   Certain Rights of Guarantee Trustee.

         (a) Subject to the provisions of Section 3.1:

                 (i) The Guarantee Trustee may rely and shall be fully
         protected in acting or refraining from acting upon any resolution,
         certificate, statement, instrument, opinion, report, notice, request,
         direction, consent, order, bond, debenture, note, other evidence of
         indebtedness or other paper or document reasonably believed by it to
         be genuine and to have been signed, sent or presented by the proper
         party or parties.

                 (ii) Any direction or act of the Guarantor contemplated by
         this Guarantee Agreement shall be sufficiently evidenced by an
         Officers' Certificate unless otherwise prescribed herein.
<PAGE>   12
                                                                               8



                 (iii) Whenever, in the administration of this Guarantee
         Agreement, the Guarantee Trustee shall deem it desirable that a matter
         be proved or established before taking, suffering or omitting to take
         any action hereunder, the Guarantee Trustee (unless other evidence is
         herein specifically prescribed) may, in the absence of bad faith on
         its part, request and rely upon an Officers' Certificate which, upon
         receipt of such request from the Guarantee Trustee, shall be promptly
         delivered by the Guarantor.

                 (iv) The Guarantee Trustee may consult with legal counsel of
         its selection, and the written advice or opinion of such legal counsel
         with respect to legal matters shall be full and complete authorization
         and protection in respect of any action taken, suffered or omitted to
         be taken by it hereunder in good faith and in accordance with such
         advice or opinion.  Such legal counsel may be legal counsel to the
         Guarantor or any of its Affiliates and may be one of its employees.
         The Guarantee Trustee shall have the right at any time to seek
         instructions concerning the administration of this Guarantee Agreement
         from any court of competent jurisdiction.

                 (v) The Guarantee Trustee shall be under no obligation to
         exercise any of the rights or powers vested in it by this Guarantee
         Agreement at the request or direction of any Holder, unless such
         Holder shall have provided to the Guarantee Trustee such adequate
         security and indemnity as would satisfy a reasonable person in the
         position of the Guarantee Trustee, against the costs, expenses
         (including attorneys' fees and expenses) and liabilities that might be
         incurred by it in complying with such request or direction, including
         such reasonable advances as may be requested by the Guarantee Trustee;
         provided that, nothing contained in this Section 3.2(a)(v) shall be
         taken to relieve the Guarantee Trustee, upon the occurrence of an
         Event of Default, of its obligation to exercise the rights and powers
         vested in it by this Guarantee Agreement.

                 (vi) The Guarantee Trustee shall not be bound to make any
         investigation into the facts or matters stated in any resolution,
         certificate, statement, instrument, opinion, report, notice, request,
         direction, consent, order, bond, debenture, note, other evidence of
         indebtedness or other paper or document, but the Guarantee Trustee, in
         its discretion, may make such further inquiry or investigation into
         such facts or matters as it may see fit.

                 (vii) The Guarantee Trustee may execute any of the trusts or
         powers hereunder or perform any duties hereunder either directly or by
         or through its agents or attorneys, and the Guarantee Trustee shall
         not be responsible for any misconduct or negligence on the part of any
         such agent or attorney appointed with due care by it hereunder.

                 (viii) Whenever in the administration of this Guarantee
         Agreement the Guarantee Trustee shall deem it desirable to receive
         written instructions with respect to enforcing any remedy or right or
         taking any other action hereunder, the Guarantee Trustee (A) may
         request instructions from the Holders, (B) may refrain from enforcing
         such remedy or right or taking such other action until such written
         instructions are received, and (C) shall be protected in acting in
         accordance with such written instructions.

                                                                               9




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

         (b) No provision of this Guarantee Agreement shall be deemed to impose
any duty or obligation on the Guarantee Trustee to perform any act or acts or
exercise any right, power, duty or obligation conferred or imposed on it in any
jurisdiction in which it shall be illegal, or in which the Guarantee Trustee
shall be unqualified or incompetent in accordance with applicable law, to
perform any such act or acts or to exercise any such right, power, duty or
obligation. No permissive power or authority available to the Guarantee Trustee
shall be construed to be a duty to act in accordance with such power and
authority.

         SECTION 3.3.   Indemnity.

         The Guarantor agrees to indemnify the Guarantee Trustee for, and to
hold it harmless against, any loss, liability or expense incurred without
negligence or bad faith on the part of the Guarantee Trustee, arising out of or
in connection with the acceptance or administration of this Guarantee
Agreement, including the costs and expenses of defending itself against any
claim or liability in connection with the exercise or performance of any of its
powers or duties hereunder.

                        ARTICLE IV.   GUARANTEE TRUSTEE

         SECTION 4.1.   Guarantee Trustee: Eligibility.

         (a) There shall at all times be a Guarantee Trustee which shall:

                 (i) not be an Affiliate of the Guarantor; and

                 (ii) be a Person that is eligible pursuant to the Trust
         Indenture Act to act as such and has a combined capital and surplus of
         at least $50,000,000, and shall be a corporation meeting the
         requirements of Section 310(a) of the Trust Indenture Act. If such
         corporation publishes reports of condition at least annually, pursuant
         to law or to the requirements of the supervising or examining
         authority, then, for the purposes of this Section and to the extent
         permitted by the Trust Indenture Act, the combined capital and surplus
         of such corporation shall be deemed to be its combined capital and
         surplus as set forth in its most recent report of condition so
         published.

         (b) If at any time the Guarantee Trustee shall cease to be eligible to
so act under Section 4.1(a), the Guarantee Trustee shall immediately resign in
the manner and with the effect set out in Section 4.2(c).
<PAGE>   14
                                                                              10




         (c) If the Guarantee Trustee has or shall acquire any "conflicting
interest" within the meaning of Section 310(b) of the Trust Indenture Act, the
Guarantee Trustee and Guarantor shall in all respects comply with the
provisions of Section 310(b) of the Trust Indenture Act.

         SECTION 4.2.   Appointment, Removal and Resignation of the Guarantee
Trustee.

         (a) Subject to Section 4.2(b), the Guarantee Trustee may be appointed
or removed without cause at any time by the Guarantor.

         (b) The Guarantee Trustee shall not be removed until a Successor
Guarantee Trustee has been appointed and has accepted such appointment by
written instrument executed by such Successor Guarantee Trustee and delivered
to the Guarantor.  If an instrument of acceptance by a Successor Guarantee
Trustee shall not have been delivered to the Guarantee Trustee within 30 days
after such removal, the Guarantee Trustee being removed may petition any court
of competent jurisdiction for the appointment of a Successor Guarantee Trustee.

         (c) The Guarantee Trustee appointed hereunder shall hold office until
a Successor Guarantee Trustee shall have been appointed or until its removal or
resignation. The Guarantee Trustee may resign from office (without need for
prior or subsequent accounting) by an instrument in writing executed by the
Guarantee Trustee and delivered to the Guarantor, which resignation shall not
take effect until a Successor Guarantee Trustee has been appointed and has
accepted such appointment by instrument in writing executed by such Successor
Guarantee Trustee and delivered to the Guarantor and the resigning Guarantee
Trustee.

         (d) If no Successor Guarantee Trustee shall have been appointed and
accepted appointment as provided in this Section 4.2 within 60 days after
delivery to the Guarantor of an instrument of resignation, the resigning
Guarantee Trustee may petition, at the expense of the Guarantor, any court of
competent jurisdiction for appointment of a Successor Guarantee Trustee. Such
court may thereupon, after prescribing such notice, if any, as it may deem
proper, appoint a Successor Guarantee Trustee.

         SECTION 5.1.   Guarantee.

         The Guarantor irrevocably and unconditionally agrees to pay in full to

paid by or on behalf of the Issuer), as and when due, regardless of any
defense, right of set-off or counterclaim which the Issuer may have or assert.
The Guarantor's obligation to make a Guarantee Payment may be satisfied by
direct payment of the required amounts by the Guarantor to the Holders or by
causing the Issuer to pay such amounts to the Holders.

                                                                              11

         SECTION 5.3.   Obligations Not Affected.

Distribution or any other sums payable under the terms of the Securities or the
extension of time for the performance of any other obligation under, arising
out of, or in connection with, the Securities;

         (d) the voluntary or involuntary liquidation, dissolution, sale of any

                                                                              12

consent of, the Guarantor with respect to the happening of any of the
foregoing.

         The Guarantor expressly acknowledges that: (i) this Guarantee Agreement
will be deposited with the Guarantee Trustee to be held for the benefit of the
Holders; (ii) the Guarantee Trustee has the right to enforce this Guarantee
Agreement on behalf of the Holders; (iii) the Holders of a Majority in aggregate

Trustee in respect of this Guarantee Agreement or exercising any trust or power
conferred upon the Guarantee Trustee under this Guarantee Agreement; and (iv)
any Holder may institute a legal proceeding directly against the Guarantor to
enforce its rights under this Guarantee Agreement, without first instituting a
legal proceeding against the Guarantee Trustee, the Issuer or any other Person.

         SECTION 5.5.   Guarantee of Payment.

         This Guarantee Agreement creates a guarantee of payment and not of

in the Trust Agreement.

         SECTION 5.6.   Subrogation.

         The Guarantor shall be subrogated to all (if any) rights of the
Holders against the Issuer in respect of any amounts paid to the Holders by the
Guarantor under this Guarantee Agreement and shall have the right to waive
payment by the Issuer pursuant to Section 5.1; provided, however, that the
Guarantor shall not (except to the extent required by mandatory provisions of
law) be entitled to enforce or exercise any rights which it may acquire by way
of subrogation or any indemnity, reimbursement or other agreement, in all cases
as a result of payment under this Guarantee Agreement, if, at the time of any
such payment, any amounts are due and unpaid under this Guarantee Agreement. If
any amount shall be paid to the Guarantor in violation of the preceding
sentence, the Guarantor agrees to hold such amount in trust for the Holders and
to pay over such amount to the Holders.

         SECTION 5.7.   Independent Obligations.

         The Guarantor acknowledges that its obligations hereunder are
independent of the obligations of the Issuer with respect to the Securities and

Guarantee Payments pursuant to the terms of this Guarantee Agreement
notwithstanding the occurrence of any event referred to in subsections (a)
through (g), inclusive, of Section 5.3 hereof.

         SECTION 6.1.   Subordination.

         The obligations of the Guarantor under this Guarantee Agreement will
constitute unsecured obligations of the Guarantor and will rank subordinate and
junior in right of payment to all Senior Indebtedness (as defined in the

such obligations expressly by their terms, in the same manner as set forth in
Article XIII of the Indenture.

         SECTION 6.2.   Pari Passu Guarantees.

         The obligations of the Guarantor under this Guarantee Agreement shall
rank pari passu with the obligations of the Guarantor under any similar
Guarantee Agreements issued by the Guarantor on behalf of the holders of
preferred securities issued by any Trust (as defined in the Indenture).


                           ARTICLE VII.   TERMINATION

         SECTION 7.1.   Termination.

         This Guarantee Agreement shall terminate and be of no further force
and effect upon (i) full payment of the Redemption Price of all Securities,
(ii) the distribution of Debentures to the Holders in exchange for all of the
Securities or (iii) full payment of the amounts payable in accordance with the
Trust Agreement upon liquidation of the Issuer. Notwithstanding the foregoing,
this Guarantee Agreement will continue to be effective or will be reinstated,
as the case may be, if at any time any Holder must restore payment of any sums
paid with respect to Securities or this Guarantee Agreement.


                         ARTICLE VIII.   MISCELLANEOUS

         SECTION 8.1.   Successors and Assigns.

         SECTION 8.2.   Amendments.

         Except with respect to any changes which do not adversely affect the
rights of the Holders or the Guarantee Trustee in any material respect (in
which case no consent of the Holders or the Guarantee Trustee, as the case may

Guarantor with the prior approval of the Holders of not less than a Majority in
Liquidation Amount of all the outstanding Securities and of the Guarantee
