                             UNDERWRITING AGREEMENT

         1. Introductory. Comerica Incorporated, a Delaware corporation (the
"COMPANY"), proposes to issue and sell from time to time certain undivided
beneficial interests represented by preferred securities (the "PREFERRED
SECURITIES") of Comerica Capital Trust I or Comerica Capital Trust II, each a
statutory business trust formed under the Business Trust Act of the State of
Delaware (the trust involved in any such offering hereinafter referred to as the
"TRUST"), guaranteed by the Company pursuant to a Guarantee Agreement (the
"GUARANTEE Agreement" and, together with the Preferred Securities and the Junior
Subordinated Debentures referred to below, the "REGISTERED SECURITIES") between
the Company and Chase Manhattan Trust Company, National Association, as
guarantee trustee (the "GUARANTEE TRUSTEE"). The Company will be the owner of
all of the undivided beneficial ownership interests represented by the common
securities (the "COMMON SECURITIES") of the Trust. The Trust will issue the
Preferred Securities and the Common Securities to the Company in exchange for
Junior Subordinated Debentures (the "JUNIOR SUBORDINATED DEBENTURES") issued by
the Company. The Junior Subordinated Debentures are to be issued pursuant to an
Indenture (the "INDENTURE") dated as of July 31, 2001, between the Company and
Chase Manhattan Trust Company, National Association, as indenture trustee (the
"INDENTURE TRUSTEE"). The Registered Securities may be issued in one or more
series, which series may vary as to distribution and interest rates, maturities,
redemption provisions, selling prices and other terms with all such terms for
any particular series of the Registered Securities being determined at the time
of sale. Particular series or offerings of Registered Securities will be sold
pursuant to a Terms Agreement referred to in Section 3, for resale in accordance
with terms of offering determined at the time of sale.

         The Registered Securities specified in Schedule A to the Terms
Agreement are hereinafter referred to as the "FIRM SECURITIES." If specified in
such Terms Agreement, the Company and the Trust may grant to the Underwriters
(as defined below) the right to purchase at their election an additional number
of Registered Securities in any such offering as provided in Section 3 hereof
(the "OPTIONAL SECURITIES"). The Firm Securities and the Optional Securities, if
any, involved in any such offering are hereinafter referred to as the "OFFERED
SECURITIES." The firm or firms which agree to purchase the Offered Securities
are hereinafter referred to as the "UNDERWRITERS" of such securities, and the
representative or representatives of the Underwriters, if any, specified in a
Terms Agreement referred to in Section 3 are hereinafter referred to as the
"REPRESENTATIVES"; provided, however, that if the Terms Agreement does not
specify any representative of the Underwriters, the term "REPRESENTATIVES", as
used in this Agreement (other than in Sections 2(b), 5(c) and 6 and the second
sentence of Section 3), shall mean the Underwriters.

         2. Representations and Warranties of the Company and the Trust. The
Company and the Trust, as of the date of each Terms Agreement referred to in
Section 3, jointly and severally, represent and warrant to, and agree with, each

         written information furnished to the Company by any Underwriter through
         the Representatives, if any, specifically for use therein.

         and each Significant Subsidiary of the Company is duly qualified to do
         business as a foreign corporation in good standing in all other
         jurisdictions in which its ownership or lease of property or the

         jurisdictions in which the failure to so qualify, individually or in
         the aggregate, would not reasonably be expected to have a Material
         Adverse Effect; all of the issued and outstanding capital stock of each
         Significant Subsidiary of the Company has been duly authorized and

         Company, directly or through subsidiaries, is owned free from liens,
         encumbrances and defects other than such liens, encumbrances and
         defects which would not individually or in the aggregate reasonably be
         expected to have a Material Adverse Effect.

Underwriters, the names of any Representatives and the number of shares of
Offered Securities to be purchased by each Underwriter the purchase price to be
paid by the Underwriters and the terms of the Offered Securities not already
specified, including but not limited to the distribution rate, maturity and any
redemption provisions. The Terms Agreement will also specify the time and date
of delivery and payment (such time and date, or such other time not later than
seven full business days thereafter as the Underwriter first named in the Terms
Agreement (the "LEAD UNDERWRITER") and the Company agree as the time for payment

in the Terms Agreement referred to as a "CLOSING DATE"), the place of delivery
and payment and any details of the terms of offering that should be reflected in
the prospectus supplement relating to the offering of the Offered Securities.
For purposes of Rule 15c6-1 under the Securities Exchange Act of 1934, the

the date for payment of funds and delivery of securities for all the Offered
Securities sold pursuant to the offering. The obligations of the Underwriters to
purchase the Offered Securities will be several and not joint. It is understood
that the Underwriters propose to offer the Offered Securities for sale as set
forth in the Prospectus.

         The Company and the Trust may specify in the Terms Agreement that the
Company and the Trust thereby grant to the Underwriters the right (an
"OVERALLOTMENT OPTION") to purchase at their election up to the number of
Optional Securities set forth in such Terms Agreement, on the terms set forth in
this section, for the sole purpose of covering over-allotments in the sale of
the Firm Securities. Any such election to purchase Optional Securities may be
exercised by written notice from the Representatives to the Company and the
Trust, given within the period specified in the Terms Agreement, setting forth
the aggregate number of Optional Securities to be purchased and the date on
which such Optional Securities are to be delivered, as determined by the
Representatives but in no event earlier than the Closing Date or, unless the
Representatives, the Company and the Trust otherwise agree in writing, earlier
than or later than the number of business days after the date of such notice set
forth in such Terms Agreement.

         The number of Optional Securities to be added to the number of Firm
Securities to be purchased by each Underwriter as set forth in Schedule A to the
Terms Agreement applicable to such Firm Securities shall be, in each case, the
number of Optional Securities which the Company has been advised by the
Representatives have been attributed to such Underwriter; provided that, if the
Company and the Trust have not been so advised, the number of Optional
Securities to be so added shall be, in each case, that proportion of Optional
Securities which the number of Firm Securities to be purchased by such
Underwriter under such Terms Agreement bears to the aggregate number of Firm
Securities (rounded as the Representatives may determine to the nearest 10
shares). The total number of Offered Securities to be purchased by all
Underwriters pursuant to such Terms Agreement shall be the aggregate number of
Firm Securities set forth in Schedule A to such Terms Agreement plus the
aggregate number of Optional Securities which the Underwriters elect to
purchase.

         The Company will deliver against payment of the purchase price the
Offered Securities in the form of one or more permanent global securities in
definitive form (the "GLOBAL SECURITIES") deposited with the Property Trustee as
custodian for The Depository Trust Company ("DTC") and registered in the name of
Cede & Co., as nominee for DTC. Interests in any permanent global securities
will be held only in book-entry form through DTC, except in the limited
circumstances described in the Prospectus. Payment for the



                                       6

Offered Securities shall be made by the Underwriters in Federal (same day) funds
by wire transfer to an account previously designated by the Company, in each
case drawn to the order of Comerica Incorporated at the place of payment
specified in the Terms Agreement on the Closing Date, against delivery to the
Property Trustee as custodian for DTC of the Global Securities representing all
of the Offered Securities.

         4. Certain Agreements of the Company and the Trust. Each of the Company
and the Trust, jointly and severally agrees with the several Underwriters that
it will furnish to counsel for the Underwriters, one copy of the signed
registration statement relating to the Registered Securities, including all
exhibits, in the form it became effective and of all amendments thereto and
that, in connection with each offering of Offered Securities:

                  (a) The Company and the Trust will file the Prospectus with
         the Commission pursuant to and in accordance with Rule 424(b)(2) (or,
         if applicable and if consented to by the Lead Underwriter, subparagraph
         (5)) not later than the second business day following the execution and
         delivery of the Terms Agreement.

                  (b) The Company and the Trust will advise the Lead Underwriter
         promptly of any proposal to amend or supplement the Registration
         Statement or the Prospectus and will afford the Lead Underwriter a
         reasonable opportunity to comment on any such proposed amendment or
         supplement; and the Company and the Trust will also advise the Lead
         Underwriter promptly of the filing of any such amendment or supplement
         and of the institution by the Commission of any stop order proceedings
         in respect of the Registration Statement or of any part thereof and
         will use its best efforts to prevent the issuance of any such stop
         order and to obtain as soon as possible its lifting, if issued.

                  (c) If, at any time when a prospectus relating to the Offered
         Securities is required to be delivered under the Act in connection with
         sales by any Underwriter or dealer, any event occurs 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 to make the statements therein, in the light of the
         circumstances under which they were made, not misleading, or if it is
         necessary at any time to amend the Prospectus to comply with the Act,
         the Company and the Trust promptly will notify the Lead Underwriter of
         such event and will promptly prepare and file with the Commission, at
         its own expense, an amendment or supplement which will correct such
         statement or omission or an amendment which will effect such
         compliance. Neither the Lead Underwriter's consent to, nor the
         Underwriters' delivery of, any such amendment or supplement shall
         constitute a waiver of any of the conditions set forth in Section 5
         hereof.

                  (d) As soon as practicable, but not later than 16 months,
         after the date of each Terms Agreement, the Company will make generally
         available to its securityholders an earnings statement covering a
         period of at least 12 months beginning after the later of (i) the
         effective date of the registration statement relating to the Registered
         Securities, (ii) the effective date of the most recent post-effective
         amendment to the Registration Statement to become effective prior to
         the date of such Terms Agreement and (iii) the date of the Company's
         most recent Annual Report on Form 10-K filed with the Commission prior
         to the date of such Terms Agreement, which will satisfy the provisions
         of Section 11(a) of the Act (including, at the option of the Company,
         Rule 158).

                  (e) The Company and the Trust will furnish to the
         Representatives copies of the Registration Statement, including all
         exhibits, any related preliminary prospectus, any related preliminary
         prospectus supplement, the Prospectus and all amendments and
         supplements to such documents, in each case as soon as available and in
         such quantities as the Lead Underwriter reasonably requests. The
         Company will pay the expenses of printing and distributing to the
         Underwriters all such documents.

                  (f) The Company and the Trust will arrange for the
         qualification of the Offered Securities for sale and the determination
         of their eligibility for investment under the laws of such
         jurisdictions as the Lead Underwriter designates and will continue such
         qualifications in effect so long as is required for the distribution,
         provided that in connection therewith the Company shall not be required
         to file a general consent to service of process in any jurisdiction or
         subject itself to taxation in respect of doing business in any
         jurisdiction in which it is not otherwise so subject.

                  (g) During the period of five years after the date of any
         Terms Agreement, the Company will furnish to the Representatives and,
         upon request, to each of the other Underwriters, if any, as soon as
         practicable after the end of each fiscal year, a copy of its annual
         report to stockholders for such year; and the Company will make
         available (including by way of filing with the Commission) to the
         Representatives as soon as available, a copy of each report and any
         definitive proxy statement of the Company filed with the Commission
         under the Securities Exchange Act of 1934 or mailed to stockholders.

                  (h) The Company will pay all expenses incident to the
         performance of its and the Trust's obligations under the Terms
         Agreement (including the provisions of this Agreement), for any filing
         fees or other expenses (including fees and disbursements of counsel) in
         connection with qualification of the Registered Securities for sale and
         any determination of their eligibility for investment under the laws of
         such jurisdictions as the Lead Underwriter may designate and the
         printing of memoranda relating thereto, for any fees charged by
         investment rating agencies for the rating of the Preferred Securities,
         for any applicable filing fee incident to, the review by the National
         Association of Securities Dealers, Inc. of the Registered Securities,
         for any travel expenses of the Company's officers and employees and any
         other expenses of the Company or the Trust in connection with attending
         or hosting meetings with prospective purchasers of Registered
         Securities and for expenses incurred in distributing the Prospectus,
         any preliminary prospectuses, any preliminary prospectus supplements or
         any other amendments or supplements to the Prospectus to the
         Underwriters.

                  (i) The Company and Trust, during a period of 30 days from
         each Closing Date, will not offer, sell, contract to sell or otherwise
         dispose of any Preferred Securities, Junior Subordinated Debentures,
         any other beneficial interests in the Trust, or any other securities
         that are substantially similar to the Preferred Securities or Junior
         Subordinated Debentures, including any guarantee of such securities, or
         any securities convertible into or exchangeable for or representing the
         right to receive Preferred Securities, Junior Subordinated Debentures
         or any such substantially similar securities, without the prior written
         consent of the Lead Underwriter.

         5. Conditions to the Obligations of the Underwriters. The obligations
of the several Underwriters to purchase and pay for the Offered Securities will
be subject to the accuracy of the representations and warranties on the part of
the Company and the Trust herein, to the accuracy of the statements of Company's
and the Trust's officers made pursuant to the provisions hereof, to the
performance by the Company and the Trust of their obligations hereunder and to

                  (a) On the date of the Terms Agreement, the Representatives

                  respects with the applicable accounting requirements of the
                  Act and the related published Rules and Regulations;

                  information as described in Statement of Auditing Standards
                  No. 71, Interim Financial Information, on any unaudited
                  financial statements included in the Registration Statement;

                           (iii) on the basis of the review referred to in
                  clause (ii) above, a reading of the latest available interim
                  financial statements of the Company, inquiries of officials of
                  the Company who have responsibility for financial and
                  accounting matters and other specified procedures, nothing
                  came to their attention that caused them to believe that:

                                    (A) the unaudited financial statements, if
                           any, and any summary of earnings included in the

                           respects with the applicable accounting requirements
                           of the Act and the related published Rules and

                           summary of earnings for them to be in conformity with
                           generally accepted accounting principles;

                                    (B) if any unaudited "capsule" information
                           is contained in the Prospectus, the unaudited
                           consolidated net sales, net operating income, net
                           income and net income per share amounts or other

                           described in such letter do not agree with the
                           corresponding amounts set forth in the unaudited
                           consolidated financial statements or were not
                           determined on a basis substantially consistent with
                           that of the corresponding amounts in the audited
                           statements of income;

                           balance sheet read by such accountants, or at a
                           subsequent specified date not more than three
                           business days prior to the date of the such letter,
                           there was any change in the common stock or any
                           increase in medium or long-term debt of the Company
                           and its consolidated subsidiaries or, at the date of

                           accountants, there was any decrease in consolidated
                           total assets, consolidated total deposits,

                           on the latest balance sheet included in the
                           Prospectus; or

                           available income statement read by such accountants
                           there were any decreases, as compared with the
                           corresponding period of the previous year and with

                  have occurred or may occur or which are described in such
                  letter; and

                           (iv) they have compared specified dollar amounts (or
                  percentages derived from such dollar amounts) and other
                  financial information contained in the Prospectus (in each
                  case to the extent that such dollar amounts, percentages and
                  other financial information are derived from the general
                  accounting records of the Company and its subsidiaries subject
                  to the internal controls of the Company's accounting system or
                  are derived directly from

                  such records by analysis or computation) with the results
                  obtained from inquiries, a reading of such general accounting
                  records and other procedures specified in such letter and have
                  found such dollar amounts, percentages and other financial
                  information to be in agreement with such results, except as
                  otherwise specified in such letter.

         All financial statements and schedules included in material
         incorporated by reference into the Prospectus shall be deemed included
         in the Prospectus for purposes of this subsection.

                  (b) On the date of the Terms Agreement, the Representatives
         shall have received a letter, dated the date of such Terms Agreement
         from KPMG LLP in respect of the consolidated financial statements of
         Imperial Bancorp and its subsidiaries as of December 31, 2000 and 1999
         for each of the years in the three year period ended December 31, 2000
         addressed to the Underwriters in form and substance satisfactory to the
         Representatives.

                  (c) The Prospectus shall have been filed with the Commission
         in accordance with the Rules and Regulations and Section 4(a) of this
         Agreement. No stop order suspending the effectiveness of the
         Registration Statement or of any part thereof shall have been issued
         and no proceedings for that purpose shall have been instituted or, to
         the knowledge of the Company, the Trust or any Underwriter, shall be
         contemplated by the Commission.

                  (d) Subsequent to the execution of the Terms Agreement, there
         shall not have occurred (i) any change, or any development or event
         involving a prospective change, in the financial condition, business or
         results of operations of the Company and its subsidiaries taken as one
         enterprise which, in the judgment of a majority in interest of the
         Underwriters including any Representatives, is material and adverse and
         makes it impractical or inadvisable to proceed with completion of the
         public offering or the sale of and payment for the Offered Securities;
         (ii) any downgrading in the rating of any debt securities or preferred
         stock of the Company by any "nationally recognized statistical rating
         organization" (as defined for purposes of Rule 436(g) under the Act),
         or any public announcement that any such organization has under
         surveillance or review its rating of any debt securities or preferred
         stock of the Company (other than an announcement with positive
         implications of a possible upgrading, and no implication of a possible
         downgrading, of such rating); (iii) any material suspension or material
         limitation of trading in securities generally on the New York Stock
         Exchange, or any setting of minimum prices for trading on such
         exchange, or any suspension of trading of any securities of the Company
         on any exchange or in the over-the-counter market; (iv) any banking
         moratorium declared by U.S. Federal or New York authorities; or (v) any
         outbreak or escalation of major hostilities in which the United States
         is involved, any declaration of war by Congress or any other
         substantial national or international calamity or emergency if, in the
         judgment of a majority in interest of the Underwriters including any
         Representatives, the effect of any such outbreak, escalation,
         declaration, calamity or emergency makes it impractical or inadvisable
         to proceed with completion of the public offering or the sale of and
         payment for the Offered Securities.

                  (e) Mayer, Brown & Platt shall have furnished to the
         Representatives a written opinion, addressed to the Underwriters and
         dated the Closing Date to the effect that;

                           (i) The Company has been duly incorporated and is an

                  delivered by the Trust.

                  thereof by the Indenture Trustee and payment and delivery as
                  provided in the Terms Agreement, constitute valid and legally
                  binding obligations of the Company enforceable against the

                  the Company in accordance with its terms, subject to the
                  effects of bankruptcy, insolvency, fraudulent transfer,
                  reorganization, moratorium and other similar laws of general
                  applicability relating to or affecting creditors' rights and

                  (f) Mark W. Yonkman, First Vice President, Assistant Secretary
         and General Counsel - Investment Bank and Finance of the Company shall
         have furnished to the Representatives a written opinion, addressed to
         the Underwriters and dated the Closing Date to the effect that:

                           (i) The Company is duly qualified to do business as a
                  foreign corporation in good standing in all jurisdictions in
                  which its ownership or lease of property or the conduct of its
                  business requires such qualification.

                           (ii) Each Significant Subsidiary of the Company has
                  been duly incorporated and is an existing corporation in good
                  standing under the laws of the jurisdiction of its
                  incorporation, with power and authority (corporate and other)
                  to own its properties and conduct its business as described in
                  the Prospectus; and each Significant Subsidiary of the Company
                  is duly qualified to do business as a foreign corporation in

                  ownership or lease of property or the conduct of its business
                  requires such qualification other than such jurisdictions in
                  which the failure to qualify, individually or in the
                  aggregate, would not reasonably be expected to have a Material
                  Adverse Effect; all of the issued and outstanding capital
                  stock of each Significant Subsidiary of the Company has been
                  duly authorized and validly issued and is fully paid and
                  nonassessable (except as provided by 12 U.S.C. ss. 55 or any
                  comparable provision of applicable state law); and the capital
                  stock of each subsidiary owned by the Company, directly or
                  through subsidiaries, is owned free from liens, encumbrances
                  and defects other than such liens, encumbrances and defects
                  which would not, individually or in the aggregate, reasonably
                  be expected to have a Material Adverse Effect.

                  the Company, the compliance with the terms of each of the

                  of the other transactions contemplated herein and therein will
                  not result in a breach or violation of any of the terms and
                  provisions of, or constitute a default under, (i) any statute,
                  any rule, regulation or order of any governmental agency or
                  body or any court, domestic or foreign, having jurisdiction
                  over the Company or any subsidiary of the Company or the Trust
                  or any of their properties, or any agreement or instrument to
                  which the Company or any such subsidiary or the Trust is a
                  party or by which the Company or any such subsidiary or the
                  Trust is bound or to which any of the properties of the
                  Company or any such subsidiary or the Trust is subject, except
                  for any breaches, violations or defaults as would not
                  individually or in the aggregate reasonably be expected to
                  have a Material Adverse Effect, or (ii) the charter or by-laws
                  of the



                                       12

                           (v) No consent, approval, authorization, order,
                  registration, filing, or qualification of or with any federal

                  knowledge, any federal or Delaware court is required for the

                  Preferred Securities, the issuance and sale of the Guarantee
                  by the Company and the compliance by the Company and the Trust
                  with all of the provisions of the Terms Agreement and the
                  consummation of the transactions contemplated by the Terms
                  Agreement, except for such consents, approvals,
                  authorizations, registrations, filings, or qualifications as

                  Indenture and such as may be required under state securities

                  except for such state banking notices which are required to be
                  given after the fact.

                           (vi) To the best of such counsel's knowledge, no
                  contracts, agreements or understandings exist between the
                  Company and any person granting such person the right to
                  require the Company to include any securities of the Company
                  owned or to be owned by such person in the securities

                  holding company under the BHC Act; and the deposit accounts of
                  the Company's domestic bank subsidiaries are insured by the

                  regulations of the FDIC, and no proceedings for the
                  termination of such insurance are pending or, to the best
                  knowledge of such counsel, threatened.

          facts have come to such counsel's attention that have caused it to
          believe that such Registration Statement, as of its effective date, or

          of the Closing Date, contained any untrue statement of a material fact

          the Closing Date, contained any untrue statement of a material fact or
          omitted to state any material fact necessary in order to make the
          statements therein, in the light of the circumstances under which they
          were made, not misleading; the descriptions in the Registration
          Statement and Prospectus of statutes, legal and governmental
          proceedings and contracts and other documents are accurate and fairly
          present the information required to be shown; and such counsel do not
          know of any legal or governmental proceedings required to be described
          in the Prospectus which are not described as required or of any
          contracts or documents of a character required to be described in the
          Registration Statement or Prospectus or to be filed as exhibits to the

         as to the Form T-1 or the financial statements or other financial data
         contained in or omitted from the Registration Statement or the
         Prospectus.

                  (g) Mayer, Brown & Platt shall have furnished to the
         Representatives its written opinion, as special United States federal
         income tax counsel to the Company and the Trust, addressed to the
         Underwriters and dated the Closing Date to the effect that:

                           (i) The Trust will be classified as a grantor trust
                  for United States federal income tax purposes and not as an
                  association taxable as a corporation;

                           (ii) The Junior Subordinated Debentures will be
                  classified as indebtedness for United States federal income
                  tax purposes; and

                           (iii) Subject to the qualifications and limitations

                  under the caption "United States Federal Income Tax
                  Consequences," insofar as they purport to constitute summaries
                  of matters of United States federal tax law and regulations or
                  legal conclusions with respect thereto, constitute accurate
                  summaries of the matters described therein in all material
                  respects.

                  (h) Richards, Layton & Finger, P.A. shall have furnished to
         the Representatives its written opinion, as special Delaware counsel to
         the Company and the Trust, addressed to the Underwriters and dated the

         Representatives, to the effect that:

                           (i) The Trust has been duly created and is 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 Trust as a business trust have been
                  made; and under the Declaration and the Delaware Business
                  Trust Act, the Trust has the trust power and authority to own
                  property and to conduct its business as described in the
                  Prospectus and to enter into and perform its obligations under
                  each of the Terms Agreement, the Preferred Securities and
                  Common Securities.

                           (ii) The Declaration constitutes a valid and legally
                  binding obligation of the Company and the Trustees, and is
                  enforceable against the Company and the Trustees, in
                  accordance with its terms, subject, as to enforcement, to the
                  effect upon the Declaration of (i) bankruptcy, insolvency,
                  moratorium, receivership, reorganization, liquidation,
                  fraudulent transfer and other similar laws relating to the
                  rights and remedies of creditors generally, (ii) principles of
                  equity, including applicable law relating to fiduciary duties
                  (regardless of whether considered and applied in a proceeding
                  in equity or at law), and (iii) the effect of applicable
                  public policy on the enforceability of provisions relating to
                  indemnification or contribution.

                           (iii) Under the Delaware Business Trust Act and the
                  Declaration, the Trust has the trust power and authority (i)
                  to execute and deliver and to perform its obligations under,
                  the Terms Agreement and (ii) to execute and deliver the
                  Preferred Securities.

                           (iv) The Preferred Securities have been duly
                  authorized by the Declaration and, when issued and delivered
                  in exchange for the Junior Subordinated Debentures as
                  described in the Prospectus, the Preferred Securities will be
                  duly and validly issued and (subject to the qualifications set
                  forth in this paragraph) fully paid and nonassessable
                  undivided beneficial interests in the assets of the Trust; the
                  holders of the Preferred Securities will be entitled to the
                  benefits of the Declaration and, as beneficial owners of the
                  Trust, will be



                                       14

                  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
                  (such counsel may note that the holders of Offered Securities
                  will be subject to the withholding provisions of Section 10.4
                  of the Declaration and will be required to make payment or
                  provide indemnity or security in connection with taxes or
                  governmental charges arising from transfers or exchanges of
                  certificates for Offered Securities and the issuance of
                  replacement certificates for Preferred Securities, and to
                  provide security or indemnity in connection with requests of

                  and powers under the Declaration, all as set forth in the
                  Declaration).

                           (v) Under the Delaware Business Trust Act and the
                  Declaration, all necessary trust action has been taken to duly
                  authorize the execution and delivery by the Trust of this
                  Agreement and the performance by the Trust of its obligations
                  thereunder.

                           (vi) Under the Delaware Business Trust Act and the
                  Declaration, the issuance of the Offered Securities is not
                  subject to preemptive rights.

                           (vii) The issuance by the Trust of the Preferred

                  contemplated by this Agreement, the compliance by the Trust
                  with its obligations thereunder and the performance by the
                  Company, as sponsor, of its obligations under the Declaration
                  (A) do not violate (i) any of the provisions of the
                  Certificate of Trust or the Declaration or (ii) any applicable
                  Delaware law or administrative regulation and (B) do not
                  require any consent, approval, license, authorization or
                  validation of, or filing or registration with, any Delaware
                  legislative, administrative or regulatory body under the laws
                  or administrative regulations of the State of Delaware (other
                  that as may be required under the securities or blue sky laws
                  of the state of Delaware, as to which such counsel need
                  express no opinion.

                           (viii) Assuming that the Trust derives no income from
                  or connected with services provided within the State of
                  Delaware and has no assets, activities (other than having a
                  Delaware Trustee as required by the Delaware Business Trust
                  Act and the filing of documents with the Secretary of State of
                  the State of Delaware) or employees in the State of Delaware,
                  the holders of the Offered Securities (other than those
                  holders of Offered 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 Trust, and the Trust will not be liable
                  for any income tax imposed by the State of Delaware.

                  (i) The Representatives shall have received from Simpson
         Thacher & Bartlett, counsel for the Underwriters, such opinion or
         opinions, dated the Closing Date, with respect to the incorporation of
         the Company, the validity of the Offered Securities, the Registration
         Statement, the Prospectus and other related matters as the
         Representatives may require, and the Company shall have furnished to
         such counsel such documents as they request for the purpose of enabling
         them to pass upon such matters.

                  (j) The Representatives shall have received a certificate,
         dated the Closing Date, of the President or any Vice President and the
         principal financial or accounting officer of the Company in



                                       15
   16

         which such officers shall state that, to their knowledge, the
         representations and warranties of the Company in this Agreement are
         true and correct, that the Company has complied with all agreements and
         satisfied all conditions on its part to be performed or satisfied
         hereunder at or prior to the Closing Date, that no stop order
         suspending the effectiveness of the Registration Statement or of any
         part thereof has been issued and no proceedings for that purpose have
         been instituted or are contemplated by the Commission and that,
         subsequent to the date of the most recent financial statements in the
         Prospectus, there has been no material adverse change, nor any
         development or event involving a prospective material adverse change,
         in the financial condition, business, properties or results of
         operations of the Company and its subsidiaries taken as a whole except
         as set forth in or contemplated by the Prospectus or as described in
         such certificate.

                  (l) The Representatives shall have received a certificate,
         dated the Closing Date, of the Administrative Trustees of the Trust in
         which such trustees, to their knowledge, shall state that the
         representations and warranties of the Trust in this Agreement are true
         and correct and that Trust has complied with all agreements and
         satisfied all conditions on its part to be performed or satisfied
         hereunder at or prior to the Closing Date.

                  (m) If the Terms Agreement specifies that the Preferred
         Securities are to be listed on a stock exchange, such stock exchange
         shall have approved the Preferred Securities for listing, subject only
         to official notice of issuance and evidence of satisfactory
         distribution.

                  (n) With respect to the letter of Ernst & Young LLP delivered
         to the Representatives concurrently with the execution of the Terms
         Agreement which meets the requirements of subsection (a) of this
         Section (the "INITIAL LETTER"), the Company shall have furnished to the
         Representatives a letter the "BRING-DOWN letter") of such accountants,
         addressed to the Underwriters and dated the Closing Date (i) stating,
         as of the date of the bring-down letter (or, with respect to matters
         involving changes or developments since the respective dates as of
         which specified financial information is given in the Prospectus, as of
         a date not more than three days prior to the date of the bring-down
         letter), the conclusions and findings of such firm with respect to the
         financial information and other matters covered by the initial letter
         and (ii) confirming in all material respects the conclusions and
         findings set forth in the initial letter.

The Company will furnish the Representatives with such conformed copies of such
opinions, certificates, letters and documents as the Representatives reasonably
request. The Lead Underwriter may in its sole discretion waive on behalf of the
Underwriters compliance with any conditions to the obligations of the
Underwriters under this Agreement and the Terms Agreement.

         6. Indemnification and Contribution. (a) The Company and the Trust,
jointly and severally, will indemnify and hold harmless each Underwriter, its
partners, directors and officers and each person, if any, who controls such
Underwriter within the meaning of Section 15 of the Act, 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 any untrue statement or alleged untrue statement of any material fact
contained in the Registration Statement, the Prospectus, or any amendment or
supplement thereto, or any related preliminary prospectus or preliminary
prospectus supplement, 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 loss, claim,
damage, liability or action as such expenses are incurred; provided, however,
that the Company will 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 in or omission or alleged omission from
any of such documents in reliance upon and in conformity with written
information furnished to the Company by any Underwriter through the
Representatives, if any, specifically for use therein, it being understood and
agreed that the only



                                       16
   17

such information furnished by any Underwriter consists of the information
described as such in the Terms Agreement; and provided, further, that with
respect to any untrue statement or alleged untrue statement in or omission or
alleged omission from any preliminary prospectus the indemnity agreement
contained in this subsection (a) shall not inure to the benefit of any
Underwriter from whom the person asserting any such losses, claims, damages or
liabilities purchased the Preferred Securities concerned, to the extent that a
prospectus relating to such Preferred Securities was required to be delivered by
such Underwriter under the Act in connection with such purchase and was not and
if the Prospectus (as amended or supplemented) would have cured the defect
giving rise to such loss, claim, damage or liability of such Underwriter unless
such failure to deliver the Prospectus was the result of non-compliance by the
Company with Section 4(e) hereof.

         (a) Each Underwriter will severally and not jointly indemnify and hold
harmless the Company and the Trust, their directors and officers and each
person, if any, who controls the Company or the Trust within the meaning of
Section 15 of the Act, against any losses, claims, damages or liabilities to
which the Company or the Trust 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 any untrue statement or alleged untrue
statement of any material fact contained in the Registration Statement, the
Prospectus, or any amendment or supplement thereto, or any related preliminary
prospectus or preliminary prospectus supplement, or arise out of or are based
upon the omission or the 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 reliance upon and in conformity with written information furnished to the
Company or the Trust by such Underwriter through the Representatives, if any,
specifically for use therein, and will reimburse any legal or other expenses
reasonably incurred by the Company or the Trust in connection with investigating
or defending any such loss, claim, damage, liability or action as such expenses
are incurred, it being understood and agreed that the only such information
furnished by any Underwriter consists of the information described as such in
the Terms Agreement.

         (b) Promptly after receipt by an indemnified party under this Section
of notice of the commencement of any action, such indemnified party will, if a
claim in respect thereof is to be made against the indemnifying party under
subsection (a) or (b) above, notify the indemnifying party of the commencement
thereof; but the omission so to notify the indemnifying party will not relieve
it from any liability which it may have to any indemnified party otherwise than
under subsection (a) or (b) above. In case any such action is brought against
any indemnified party and it notifies the indemnifying party of the commencement
thereof, the indemnifying party will be entitled to participate therein and, to
the extent that it may 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 will not be liable to such indemnified
party under this Section for any legal or other expenses subsequently incurred
by such indemnified party in connection with the defense thereof other than
reasonable costs of investigation. No indemnifying party shall, without the
prior written consent of the indemnified party, effect any settlement of any
pending or threatened action in respect of which any indemnified party is or
could have been a party and indemnity could have been sought hereunder by such
indemnified party unless such settlement (i) includes an unconditional release
of such indemnified party from all liability on any claims that are the subject
matter of such action and (ii) does not include a statement as to, or an
admission of, fault, culpability or a failure to act by or behalf of an
indemnified party.

                  (c) If the indemnification provided for in this Section is
         unavailable or insufficient to hold harmless an indemnified party under
         subsection (a) or (b) above, then each indemnifying party shall
         contribute to the amount paid or payable by such indemnified party as a
         result of the losses, claims, damages or liabilities referred to in
         subsection (a) or (b) above (i) in such proportion as is appropriate to
         reflect the relative benefits received by the Company and the Trust on
         the one hand



                                       17
   18

         and the Underwriters on the other from the offering of the Offered
         Securities or (ii) if the allocation provided by clause (i) above is
         not permitted by applicable law, in such proportion as is appropriate
         to reflect not only the relative benefits referred to in clause (i)
         above but also the relative fault of the Company and the Trust on the
         one hand and the Underwriters on the other in connection with the
         statements or omissions which resulted in such losses, claims, damages
         or liabilities as well as any other relevant equitable considerations.
         The relative benefits received by the Company and the Trust on the one
         hand and the Underwriters on the other shall be deemed to be in the
         same proportion as the total net proceeds from the offering (before
         deducting expenses) received by the Company 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 Trust or the
         Underwriters and the parties' relative intent, knowledge, access to
         information and opportunity to correct or prevent such untrue statement
         or omission. The amount paid by an indemnified party as a result of the
         losses, claims, damages or liabilities referred to in the first
         sentence of 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 action or claim which is
         the subject of this subsection (d). 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
         Offered 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 obligations of the Company and the Trust under this Section
shall be in addition to any liability which the Company or the 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 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 director of the Company and
the Trust, to each officer of the Company and the Trust who has signed the
Registration Statement and to each person, if any, who controls the Company or
the Trust within the meaning of the Act.

         8. Default of Underwriters. If any Underwriter or Underwriters default
in their obligations to purchase Offered Securities under the Terms Agreement
and the aggregate number of shares of Preferred Securities that such defaulting
Underwriter or Underwriters agreed but failed to purchase does not exceed 10% of
the total number of shares of Preferred Securities, the Lead Underwriter may
make arrangements satisfactory to the Company and the Trust for the purchase of
such Preferred Securities by other persons, including any of the Underwriters,
but if no such arrangements are made by the Closing Date, the non-defaulting
Underwriters shall be obligated severally, in proportion to their respective
commitments under the Terms Agreement (including the provisions of this
Agreement), to purchase the Preferred Securities that such defaulting
Underwriters agreed but failed to purchase. If any Underwriter or Underwriters
so default and the aggregate number of shares of Preferred Securities with
respect to which such default or defaults occur exceeds 10% of the total number
of shares of Preferred Securities and arrangements satisfactory to the Lead
Underwriter, the Company and the Trust for the purchase of such Preferred
Securities by other persons are not made within 36 hours after such default, the
Terms Agreement will terminate without liability on the part of any
non-defaulting Underwriter, the Company or the Trust, except as provided in
Section 8. As used in this Agreement, the term "Underwriter" includes any person
substituted for an Underwriter under this Section. Nothing herein will relieve a
defaulting Underwriter from liability for its default.


                                       18
   19

         9. Survival of Certain Representations and Obligations. The respective
indemnities, agreements, representations, warranties and other statements of the
Company, the Trust or their respective officers and of the several Underwriters
set forth in or made pursuant to the Terms Agreement (including the provisions
of this Agreement) will remain in full force and effect, regardless of any
investigation, or statement as to the results thereof, made by or on behalf of
any Underwriter, the Company, the Trust or any of their respective
representatives, officers or directors or any controlling person, and will
survive delivery of and payment for the Offered Securities. If the Terms
Agreement is terminated pursuant to Section 7 or if for any reason the purchase
of the Offered Securities by the Underwriters is not consummated, the Company
and the Trust shall remain responsible for the expenses to be paid or reimbursed
by it pursuant to Section 4 and the respective obligations of the Company, the
Trust and the Underwriters pursuant to Section 6 shall remain in effect. If the
purchase of the Preferred Securities by the Underwriters is not consummated for
any reason other than solely because of the termination of the Terms Agreement
pursuant to Section 7 or the occurrence of any event specified in clause (iii),
(iv) or (v) of Section 5(d), the Company and the Trust will reimburse the
Underwriters for all out-of-pocket expenses (including fees and disbursements of
counsel) reasonably incurred by them in connection with the offering of the
Offered Securities.

         10. Notices. All communications hereunder will be in writing and, if
sent to the Underwriters, will be mailed, delivered or telegraphed and confirmed
to them at their address furnished to the Company in writing for the purpose of
communications hereunder or, if sent to the Company or the Trust, will be
mailed, delivered or telegraphed and confirmed to it at

         11. Successors. The Terms Agreement (including the provisions of this
Agreement) will inure to the benefit of and be binding upon the Company and the
Trust and such Underwriters as are identified in the Terms Agreement and their
respective successors and the officers and directors and controlling persons
referred to in Section 6, and no other person will have any right or obligation
hereunder.

         12. Representation of Underwriters. Any Representatives will act for
the several Underwriters in connection with the financing described in the Terms
Agreement, and any action under such Terms Agreement (including the provisions
of this Agreement) taken by the Representatives jointly or by the Lead
Underwriter will be binding upon all the Underwriters.

         13. Counterparts. The Terms Agreement may be executed in any number of
counterparts, each of which shall be deemed to be an original, but all such
counterparts shall together constitute one and the same Agreement.

         1. APPLICABLE LAW. THIS AGREEMENT AND THE TERMS AGREEMENT SHALL BE
GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH, THE LAWS OF THE STATE OF NEW
YORK.

         The Company and the Trust hereby submit to the non-exclusive
jurisdiction of the Federal and state courts in the Borough of Manhattan in The
City of New York in any suit or proceeding arising out of or relating to the
Terms Agreement (including the provisions of this Agreement) or the transactions
contemplated thereby.
