                             UNDERWRITING AGREEMENT

                                                              August 4, 1999
LEHMAN BROTHERS INC.
Three World Financial Center
New York, New York 10285

Ladies and Gentlemen:

     Bank United Corp., a Delaware corporation (the "Company"), confirms its
agreement with Lehman Brothers Inc. (the "Underwriter"), with respect to the
issue and sale by the Company and purchase by the Underwriter of 2,000,000
Premium Income Equity Securities ("PIES") (the "Firm PIES"). In addition, the
Company proposes to grant to the Underwriter an option to purchase up to an
additional 300,000 PIES on the terms and for the purposes set forth in Section 2
(the "Option PIES"). The Firm PIES and the Option PIES, if purchased, are
hereinafter collectively called the "PIES." Capitalized terms used herein
without definition shall be used as defined in the Final Prospectus (as
hereinafter defined).

     Each PIES will initially consist of a unit (a "Corporate PIES") comprised
of (a) a stock purchase contract (a "Purchase Contract") under which (i) the
holder will purchase from the Company no later than August 15, 2002, for $50, a
number of shares of common stock, par value $0.01 per share, of the Company (the
"Common Stock"), equal to the Settlement Rate as set forth in the Purchase
Contract Agreement (as hereinafter defined) and (ii) the Company will pay to the
holder contract adjustment payments and (b) a share of the Company's Series B
Preferred Stock, liquidation preference $50 per share (the "Preferred Stock").
In accordance with the terms of a Purchase Contract Agreement (the "Purchase
Contract Agreement") to be entered into between the Company and The First
National Bank of Chicago, as Purchase Contract Agent (the "Purchase Contract
Agent"), the holders of the PIES will pledge the Preferred Stock to The Bank of
New York, as Collateral Agent (the "Collateral Agent"), pursuant to a Pledge
Agreement (the "Pledge Agreement") to be entered into among the Company, the
Purchase Contract Agent, The Bank of New York, as Securities Intermediary (the
"Securities Intermediary"), and the Collateral Agent, to secure the holders'
obligations to purchase Common Stock under the Purchase Contracts.

     This is to confirm the agreement concerning the purchase of the PIES by the
Underwriter.

     1. Representations, Warranties and Agreements of the Company. The Company
represents, warrants and agrees that:

          (a) A registration statement on Form S-3 (File No. 333-75937) and an
     amendment or amendments thereto with respect to the offering and sale of
     securities of the Company, including the PIES have (i) been prepared by the
     Company in conformity with the requirements of the Securities Act of 1933,
     as amended (the "Securities Act"), and the rules and regulations (the
     "Rules and Regulations") of the Securities and Exchange Commission (the
     "Commission") thereunder, (ii) been filed with the Commission under the
     Securities Act and (iii) become effective under the Securities Act. The
     registration statement, as amended at the date of this Agreement, meets the
     requirements set forth in Rule 415(a)(1)(x) under the Securities Act and
     complies in all other material respects with such Rule. The Company
     proposes to file with the Commission pursuant to Rule 424(b) under the
     Securities Act ("Rule 424(b)") a supplement to the form of prospectus
     included in the registration statement relating to the initial offering of
     the PIES and the plan of distribution thereof and has previously advised
     you of all further information (financial and other) with respect to the
     Company to be set forth therein. The term "Registration Statement" means
     the registration statement, as amended at the date of this Agreement and as
     amended from time to time hereafter, including the exhibits thereto, and
     all documents incorporated therein by reference pursuant to Item 12 of Form
     S-3 (the "Incorporated Documents"), and the prospectus, in the form in
     which it appeared in the Registration Statement at the time the
     Registration Statement became effective, including the Incorporated
     Documents, is hereinafter referred to as the "Basic Prospectus"; and such
     supplemented form of prospectus, in the form in which it shall be filed
     with the Commission pursuant to Rule 424(b) (including the Basic Prospectus
     as so supplemented), is hereinafter called the "Final Prospectus". The form
     of preliminary prospectus included in Amendment No. 1 to the registration
     statement as filed with the Commission on July 29, 1999, including the form
     of preliminary prospectus supplement dated July 29, 1999 relating to the
     PIES which was also included therein, is hereinafter referred to as the
     "Preliminary Prospectus". Any reference herein to the Registration
     Statement, the Preliminary Prospectus or the Final Prospectus shall be
     deemed to refer to and include the Incorporated Documents which were filed
     under the Securities Exchange Act of 1934, as amended (the "Exchange Act"),
     on or before the date of this Agreement, the issue date of the Preliminary
     Prospectus or the issue date of the Final Prospectus, as the case may be;
     and any reference herein to the terms "amend", "amendment" or "supplement"
     with respect to the Registration Statement, the Preliminary Prospectus or
     the Final Prospectus shall be deemed to refer to and include the filing of
     any Incorporated Documents under the Exchange Act after the date of this
     Agreement or the issue date of the Basic Prospectus, the Preliminary
     Prospectus or the Final Prospectus, as the case may be, and deemed to be
     incorporated therein by reference. Copies of the Registration Statement
     (including any amendment or amendments to such Registration Statement) have
     been delivered by the Company to the Underwriter.

          (b) (i) Each document, if any, filed or to be filed pursuant to the
     Exchange Act and incorporated by reference in the Interim Prospectus or
     Final Prospectus complied or will comply when so filed in all material
     respects with the Exchange Act and the applicable rules and regulations of
     the Commission thereunder, (ii) the Registration Statement, when it became
     effective, did not contain and, as amended or supplemented, if applicable,
     will not contain any untrue statement of a material fact or omit to state a
     material fact required to be stated therein or necessary to make the
     statements therein not misleading, (iii) the Preliminary Prospectus

     information concerning the Underwriter furnished to the Company by the
     Underwriter or on behalf of the Underwriter specifically for inclusion

     Contract Agent as attorney-in-fact for the holders thereof and due
     authentication by the Purchase Contract Agent) and delivered by the Company
     and upon payment therefor as set forth herein, will be duly and validly
     issued and outstanding, and will constitute valid and binding obligations
     of the Company entitled to the benefits of the Purchase Contract Agreement
     and enforceable against the Company in accordance with their terms, except

     (including, without limitation, all laws relating to fraudulent transfers),
     reorganization, moratorium or other similar laws affecting the enforcement
     of creditors' rights generally or by general equitable principles

     faith and fair dealing.

          (f) The Purchase Contract Agreement has been duly authorized by the
     Company and, when duly executed by the proper officers of the Company
     (assuming due execution and delivery by the Purchase Contract Agent) and
     delivered by the Company, will constitute a valid and binding agreement of
     the Company enforceable against the Company in accordance with its terms,
     except as the enforcement thereof may be limited by the Bankruptcy
     Exceptions and an implied covenant of good faith and fair dealing.

          (g) The Pledge Agreement has been duly authorized by the Company and,
     when duly executed by the proper officers of the Company (assuming due
     execution and delivery by the Purchase Contract Agent, the Securities
     Intermediary and the Collateral Agent) and delivered by the Company, will
     constitute a valid and binding agreement of the Company enforceable against

     faith and fair dealing.

     supporting schedules thereto included or incorporated by reference in the

     public accountants as required by the Securities Act and the Rules and
     Regulations.

          (k) Neither the Company nor any of its subsidiaries has sustained
     since the date of the latest audited financial statements included or
     incorporated by reference

<PAGE>
                                                                          5


     in the Final Prospectus any 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 or
     as would not have a material adverse effect on the consolidated financial
     position, stockholders' equity, results of operations, business or
     prospects of the Company (a "Material Adverse Effect"); and, since such
     date there has not been any material change in the capital stock 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, otherwise than as set forth or contemplated in the Final
     Prospectus.

          (l) The consolidated financial statements included in the Registration
     Statement and the Final Prospectus, together with the related schedules and
     notes, present fairly in all material respects the consolidated financial
     position of the Company and its consolidated subsidiaries at the dates
     indicated and the results of operations, changes in stockholders' equity
     and cash flows of the Company and its consolidated subsidiaries for the
     periods specified; said financial statements have been prepared in
     conformity with generally accepted accounting principles ("GAAP") applied
     on a consistent basis throughout the periods involved, except as may be
     noted therein. The selected financial data and the summary financial
     information included in the Final Prospectus present fairly in all material
     respects the information shown therein and have been compiled on a basis
     consistent with that of the audited financial statements included in the
     Registration Statement.

          (m) Since the respective dates as of which information is given in the
     Registration Statement and the Final Prospectus, except as otherwise stated
     therein, (i) there has been no material adverse change in the condition,
     financial or otherwise, or in the earnings, stockholders' equity, business
     affairs or business prospects of the Company and its subsidiaries
     considered as one enterprise, whether or not arising in the ordinary course
     of business, (ii) there have been no transactions entered into by the
     Company or any of its subsidiaries, other than those in the ordinary course
     of business, which are material with respect to the Company and its
     subsidiaries considered as one enterprise, and (iii) except for regular
     quarterly dividends on the Common Stock or on the Series A Preferred Stock
     of Bank United (the "Bank") or on the Series B Preferred Stock of the Bank
     or on the Common Stock of the Bank in amounts per share that are consistent
     with past practice, there has been no dividend or distribution of any kind
     declared, paid or made by the Bank or the Company on any class of its
     capital stock.

          (n) The Company, and each of its subsidiaries including the Bank, has
     been duly organized and is validly existing as a corporation or as a
     federal savings bank, as the case may be, in good standing under the laws
     of its jurisdiction and has all necessary corporate power and authority to
     own, lease and operate its properties and to conduct its business as
     described in the Final Prospectus; the Company has all

<PAGE>
                                                                          6


     necessary corporate power and authority to enter into and perform its
     obligations under this Agreement, the Purchase Contract Agreement, the
     Pledge Agreement and the Remarketing Agreement; and the Company and each of
     its subsidiaries is duly qualified as a foreign corporation to transact
     business and is in good standing in each other jurisdiction in which such
     qualification is required, whether by reason of the ownership or leasing of
     property or the conduct of business, except where the failure so to qualify
     or to be in good standing would not result in a Material Adverse Effect.
     (o) (i) The Bank is the only "significant subsidiary" of the Company (as
     such term is defined in Rule 1-02 of Regulation S-X). The only subsidiaries
     of the Company other than the Bank are the wholly-owned subsidiaries of the
     Bank listed on Schedule 1 hereto which, considered in the aggregate as a
     single subsidiary, do not constitute a "significant subsidiary" as defined
     in Rule 1-02 of Regulation S-X. The activities of all of the Bank's
     subsidiaries are permitted to subsidiaries of a federally chartered savings
     bank, the deposits of which are insured by the Savings Association
     Insurance Fund ("SAIF"), which is administered by the Federal Deposit
     Insurance Corporation (the "FDIC").

          (ii) All of the issued and outstanding capital stock of the Bank and
     each subsidiary of the Bank has been duly authorized and validly issued, is
     fully paid and non-assessable and, except as otherwise disclosed in the
     Final Prospectus, and, other than the Series A Preferred Stock of the Bank
     and the Series B Preferred Stock of the Bank, is owned by the Company,
     directly or through subsidiaries, free and clear of any security interest,
     mortgage, pledge, lien, encumbrance, claim or equity; none of the
     outstanding shares of capital stock of any subsidiary was issued in
     violation of the preemptive or similar rights of any securityholder of such
     subsidiary.

          (p) The authorized, issued and outstanding capital stock of the
     Company is as set forth in the Final Prospectus under the caption
     "Capitalization" (except for subsequent issuances, if any, pursuant to
     reservations, agreements or employee benefit plans referred to in the Final
     Prospectus). The shares of issued and outstanding capital stock have been
     duly authorized and validly issued and are fully paid and non-assessable;
     none of the outstanding shares of capital stock was issued in violation of
     the preemptive or other similar rights of any securityholder of the
     Company.

          (q) Neither the Company nor any of its subsidiaries is in violation of
     its charter or by-laws or in default in the performance or observance of
     any obligation, agreement, covenant or condition contained in any contract,
     indenture, mortgage, deed of trust, loan or credit agreement, note, lease
     or other agreement or instrument to which the Company or any of its
     subsidiaries is a party or by which it or any of them may be bound, or to
     which any of the assets, properties or operations of the

                                                                          7


     Company or any of its subsidiaries is subject (collectively, "Agreements
     and Instruments"), except for such defaults that would not result in a
     Material Adverse Effect. The execution, delivery and performance of this
     Agreement, the Purchase Contract Agreement, the Pledge Agreement and the
     Remarketing Agreement and any other agreement or instrument entered into or
     issued or to be entered into or issued by the Company in connection with
     the transactions contemplated hereby or thereby and the consummation of the
     transactions contemplated herein (including the issuance and sale of the
     Corporate PIES, the Preferred Stock and the Common Stock to be issued and
     sold pursuant to the Purchase Contract and the use of the proceeds from the
     sale of the Corporate PIES as described in the Final Prospectus under the
     caption "Use of Proceeds" (collectively, the "Transactions") and compliance
     by the Company with its obligations hereunder and thereunder have been duly
     authorized by all necessary corporate action and do not and will not,
     whether with or without the giving of notice or passage of time or both,
     conflict with or constitute a breach of, or default or Repayment Event (as
     defined below) under, or result in the creation or imposition of any lien,
     charge or encumbrance upon any assets, properties or operations of the
     Company or any of its subsidiaries pursuant to, any Agreements and
     Instruments (except for such conflicts, breaches or defaults or liens,
     charges or encumbrances that would not result in a Material Adverse
     Effect), nor will such action result in any violation of the provisions of
     the charter or by-laws of the Company or any of its subsidiaries or (except
     for such violations that would not result in a Material Adverse Effect) any
     applicable law, statute, rule, regulation, judgment, order, writ or decree
     of any government, government instrumentality or court, domestic or
     foreign, having jurisdiction over the Company or any of its subsidiaries or
     any of their assets, properties or operations. As used herein, a "Repayment
     Event" means any event or condition which gives the holder of any note,

     Company is not aware of any existing or imminent labor disturbance by the
     employees of any of its or any subsidiary's principal suppliers,
     manufacturers, customers or contractors, which, in either case, may
     reasonably be expected to result in a Material Adverse Effect.

          (s) There is no action, suit, proceeding, inquiry or investigation
     before or brought by any court or governmental agency or body, domestic or
     foreign, now pending, or, to the knowledge of the Company, threatened,

     individually or in the aggregate for all such actions, suits, proceedings,
     inquiries or investigations is required to be disclosed in the Registration
     Statement (other than as disclosed therein), or which might

     might reasonably be expected to materially and adversely affect the
     consummation of the Transactions or the performance by the Company of its
     obligations hereunder and thereunder; the aggregate of all pending legal or
     governmental proceedings to which the Company or any of its subsidiaries is
     a party or of which any of their respective property or assets is the
     subject which are not described in the Registration Statement, including
     ordinary routine litigation incidental to the business of the Company or
     any of its subsidiaries, could not reasonably be expected to result in a
     Material Adverse Effect. Neither the Company nor any of its subsidiaries is

     commitment letter or similar undertaking to, or subject to any order or
     directive issued by, or a recipient of any extraordinary supervisory letter
     from, or has adopted any board resolutions at the request of, any federal
     or state government agency or authority with responsibility for the
     supervision or regulation of depository institutions or their holding
     companies or the insurance of deposits, which in any such case materially
     restricts the conduct of its business or in any manner relates to its
     capital adequacy, its credit policies or its management, nor has the
     Company or any of its subsidiaries been advised by any such regulatory
     authority that it is contemplating issuing or requesting any such order,
     decree, written agreement, memorandum of understanding, extraordinary
     supervisory letter, commitment letter or similar undertakings or board
     resolutions.

          (t) There are no contracts or documents which are required to be

     procedures), trademarks, service marks, trade names or other intellectual
     property (collectively, "Intellectual Property") necessary to carry on the
     business now operated by them, and neither the Company nor any of its
     subsidiaries has received any notice or is otherwise aware of any
     infringement of or conflict with asserted rights of others with respect to
     any Intellectual Property or of any facts or circumstances which would
     render any Intellectual Property invalid or inadequate to protect the
     interest of the Company or any of its subsidiaries therein, and which
     infringement or conflict (if the subject of any unfavorable decision,
     ruling or finding) or invalidity or inadequacy, singly or in the aggregate,
     would result in a Material Adverse Effect.

          (v) No filing with, or authorization, approval, consent, license,
     order, registration, qualification or decree of, any court or governmental
     authority or agency, including, without limitation, the OTS and the FDIC,

     approvals, consents and other authorizations (collectively, "Governmental
     Licenses") issued by the appropriate federal, state, local or foreign
     regulatory agencies or bodies necessary to conduct the business now
     operated by them; the Company and its subsidiaries are in compliance with
     the terms and conditions of all such Governmental Licenses, except where
     the failure so to comply would not, singly or in the aggregate, have a
     Material Adverse Effect; all of the Governmental Licenses are valid and in
     full force and effect, except when the invalidity of such Governmental
     Licenses or the failure of such Governmental Licenses to be in full force
     and effect would not have a Material Adverse Effect; and neither the
     Company nor any of its subsidiaries has received any notice of proceedings
     relating to the revocation or modification of any such Governmental
     Licenses which, singly or in the aggregate, if the subject of an
     unfavorable decision, ruling or finding, would result in a Material Adverse
     Effect.

     all real, tangible and intangible property reflected in the most recent
     balance sheet included in the Final Prospectus as owned by the Company and

     property, render title unmarketable as to a material part thereof and all
     of the leases and subleases material to the business of the Company and its
     subsidiaries, considered as one enterprise, and under which the Company or
     any of its subsidiaries holds properties described in the Final Prospectus,
     are in full force and effect, and neither the Company nor any subsidiary
     has any notice of any material claim of any sort that has been asserted by
     anyone adverse to the rights of the Company or any subsidiary under any of
     the leases or subleases mentioned above, or affecting or questioning the
     rights of the Company or such subsidiary to the continued possession of the
     leased or subleased premises under any such lease or sublease.

     consent, decree or judgment, relating to pollution or protection of human
     health, the environment (including, without limitation, ambient air,
     surface water, groundwater, land surface or subsurface strata) or wildlife,
     including, without limitation, laws and regulations relating to the release
     or threatened release of chemicals, pollutants, contaminants, wastes, toxic
     substances, hazardous substances, petroleum or petroleum products

     any assessments with respect thereto.

          (ae) In the event the Company shall become either directly or
     indirectly a bank holding company for purposes of the Bank Holding Company
     Act of 1956, as amended (the "BHC Act") and the rules and regulations of
     the Board of Governors of the Federal Reserve System thereunder (the "BHC
     Rules"), the current activities of the Company and its subsidiaries (as

     holding company under the BHC Act and the BHC Rules.

          (af) The Company has not taken and will not take, directly or
     indirectly, any action designed to, or that might be reasonably expected

          (ag) The Company has satisfied the conditions for use of Form S-3, as
     set forth in the General Instructions thereto.

     2. Purchase of the PIES by the Underwriter. On the basis of the

conditions of, this Agreement, the Company agrees to sell 2,000,000 Firm PIES to
the Underwriter and the Underwriter agrees to purchase 2,000,000 Firm PIES.

     In addition, the Company grants to the Underwriter an option to purchase up
to 300,000 Option PIES. Such option is granted solely for the purpose of
covering over-allotments in the sale of the Firm PIES and is exercisable as
provided in Section 4 hereof.

     The price of both the Firm PIES and any Option PIES shall be $48.50 per
PIES.

     The Company shall not be obligated to deliver any of the PIES to be
delivered on the First Delivery Date (as hereinafter defined) or the Second
Delivery Date (as hereinafter defined), as the case may be, except upon payment
for all the PIES to be purchased on such Delivery Date as provided herein.

     3. Offering of PIES by the Underwriter. The Underwriter proposes to offer
the Firm PIES for sale upon the terms and conditions set forth in the Final
Prospectus.

     4. Delivery of and Payment for the PIES. Delivery of and payment for the
PIES shall be made at the office of Simpson Thacher & Bartlett at 425 Lexington
Avenue, New York, New York, at 8:30 A.M., New York City time, on the third full
business day following the date of this Agreement (unless the sale of the PIES
hereunder has been priced after 4:30 p.m. Eastern time on the date of this
Agreement, in which case the fourth full business day following the date of this
Agreement) or at such other date or place as shall be determined by agreement
between the Underwriter and the Company. This date and time are sometimes
referred to as the "First Delivery Date." On the First Delivery Date, the
Company, through the facilities of The Depository Trust Company ("DTC"), shall
deliver or cause to be delivered a securities entitlement with respect to the
Firm PIES to the Underwriter against payment to or upon the order of the Company
of the purchase price by wire transfer of same-day funds to a bank account
designated by the Company. Time shall be of the essence, and delivery at the
time and place specified pursuant to this Agreement is a further condition of
the obligation of the Underwriter hereunder. Upon delivery, the Firm PIES shall
be registered in the name of Cede & Co., as nominee for DTC.

     At any time on or before the thirtieth day after the date of this Agreement
the option granted in Section 2 may be exercised by written notice being given
to the Company by the Underwriter. Such notice shall set forth the aggregate
number of Option PIES as to which the option is being exercised, the names in
which the Option PIES are to be registered, the denominations in which the
Option PIES are to be issued and the date and time, as determined by the
Underwriter, when the Option PIES are to be delivered; provided, however, that
this date and time shall not be earlier than the First Delivery Date nor earlier
than the second business day after the date on which the option shall have been
exercised nor later than the fifth business day after the date on which the
option shall have been exercised. The date and time the Option PIES are
delivered are sometimes referred to as the "Second Delivery Date" and the First
Delivery Date and the Second Delivery Date are sometimes each referred to as a
"Delivery Date".

     Delivery of and payment for the Option PIES shall be made at the place
specified in the first sentence of the first paragraph of this Section 4 (or at
such other place as shall be determined by agreement between the Underwriter and
the Company) at 8:30 A.M., New York City time, on the Second Delivery Date. On
the Second Delivery Date, the Company, through the facilities of DTC, shall
deliver or cause to be delivered a securities entitlement with respect to the
Option PIES to the Underwriter against payment to or upon the order of the
Company of the purchase price by wire transfer of same-day funds to a bank
account designated by the Company. Time shall be of the essence, and delivery at
the time and place specified pursuant to this Agreement is a further condition
of the obligation of the Underwriter hereunder. Upon delivery, the Option PIES
shall be registered in the name of Cede & Co., as nominee of DTC.

     The Preferred Stock underlying the PIES will be pledged with the Collateral
Agent to secure the holders' obligations to purchase Common Stock under the
Purchase Contracts. Such pledge shall be effected by the transfer to the
Securities Intermediary of the Preferred Stock to be pledged to the Collateral
Agent in accordance with the Pledge Agreement.

     amendment of the Registration Statement containing an amended Final
     Prospectus to be made effective as soon as possible and to prepare and
     furnish without charge to the Underwriter and to any dealer in securities
     as many copies as the Underwriter may from time to time reasonably request
     of an amended or supplemented Final Prospectus which will correct such
     statement or omission or effect such compliance.

          (d) To file promptly with the Commission any amendment to the
     Registration Statement or the Final Prospectus or any supplement to the

          execute, deliver and perform its obligations under the Purchase

          Agreement, and the authentication and delivery of the PIES, have been

          Purchase Contract Agent, enforceable against the Purchase Contract

               (iii)The execution, delivery and performance of the Purchase
          Contract Agreement and the Pledge Agreement by the Purchase Contract
          Agent does not conflict with or constitute a breach of the charter or
          by-laws of the Purchase Contract Agent.

          Pledge Agreement.

          (f) The Underwriter shall not have discovered and promptly disclosed
     to the Company on or prior to such Delivery Date that the Registration
     Statement or the Final Prospectus or any amendment or supplement thereto
     contains any untrue statement of a fact which, in the opinion of Simpson
     Thacher & Bartlett, counsel for the Underwriter, is material or omits to
     state any fact which, in the opinion of such counsel, is material and (i)
     is required to be stated therein or (ii) is necessary to make the
     statements therein not misleading.

     respects to counsel for the Underwriter, and the Company shall have
     furnished to such counsel all documents and information that they may
     reasonably request to enable them to pass upon such matters.

          (h) At the time of execution of this Agreement, the Underwriter shall

     Marwick LLP, in form and substance satisfactory to the Underwriter,
     addressed to the Underwriter and dated the date hereof (i) confirming that
     they are independent public accountants within the meaning of the
     Securities Act and are in compliance with the applicable requirements
     relating to the qualification of accountants under Rule 2-01 of Regulation
     S-X of the Commission, (ii) stating, as of the date hereof (or, with
     respect to matters involving changes or developments since the respective
     dates as of which specified financial information is given in the Final
     Prospectus, as of a date not more than five days prior to the date hereof),
     the conclusions and findings of such firm with respect to the financial
     information and other matters ordinarily covered by accountants' "comfort
     letters" to underwriters in connection with registered public offerings.

          (i) With respect to the letters of Deloitte & Touche LLP and of KPMG
     Peat Marwick LLP referred to in the preceding paragraph and delivered to
     the Underwriter concurrently with the execution of this Agreement (the

     the Final Prospectus, as of such Delivery Date, did not include any untrue
     statement of a material fact and did not omit to state any material fact
     required to be stated therein or necessary to make the statements therein
     not misleading, and (B) since the date of this Agreement, no event has
     occurred which should have been set forth in a supplement or amendment to
     the Registration Statement or the Final Prospectus.

          (k) On each Delivery Date, counsel for the Underwriter shall have been
     furnished with such documents as they may require for the purpose of
     enabling them to pass upon the issuance and sale of the PIES as herein

     and all proceedings taken by the Company in connection with the issuance
     and sale of the PIES as herein contemplated shall be satisfactory in form
     and substance to the Underwriter and counsel for the Underwriter.

          (l) There shall not have been, since the date hereof or since the
     respective dates as of which information is given in the Final Prospectus,
     any material adverse change in the condition, financial or otherwise, or in
     the consolidated financial position, stockholders' equity, results of
     operations, business or prospects of the Company and its subsidiaries
     considered as one enterprise, whether or not arising in the ordinary course
     of business.

          (m) Subsequent to the execution and delivery of this Agreement (i) no
     downgrading shall have occurred in the rating accorded the Company's or any
     significant subsidiary's debt securities or preferred stock by any
     "nationally recognized statistical rating organization", as that term is
     defined by the Commission for purposes of Rule 436(g)(2) of the Rules and
     Regulations 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 or any significant
     subsidiary's debt securities or preferred stock.

          (n) Subsequent to the execution and delivery of this Agreement there
     shall not have occurred any of the following: (i) trading in securities
     generally on the New York Stock Exchange or the American Stock Exchange or
     in the over-the-counter market, or trading in any securities of the Company
     on any exchange or in the over-the-counter market, shall have been
     suspended or minimum prices shall have been established on any such
     exchange or such market by the Commission, by such exchange or by any other
     regulatory body or governmental authority having jurisdiction, (ii) a
     banking moratorium shall have been declared by Federal or state
     authorities, (iii) the United States shall have become engaged in
     hostilities, there shall have been an escalation in hostilities involving
     the United States or there shall have been a declaration of a national

     such a material adverse change in general economic, political or financial
     conditions (or the effect of international conditions on the financial
     markets in the United States shall be such) as to make it, in the judgment
     of the Underwriter, impracticable or inadvisable to proceed with the public
     offering or delivery of the PIES on the terms and in the manner
     contemplated in the Final Prospectus.

          (o) The New York Stock Exchange, Inc. shall have approved the

                                                                         20


     All opinions, letters, evidence and certificates mentioned above or
elsewhere in this Agreement shall be deemed to be in compliance with the
provisions hereof only if they are in form and substance reasonably satisfactory

     8. Indemnification and Contribution

     (a) The Company shall indemnify and hold harmless the Underwriter, its
officers and employees and each person, if any, who controls the Underwriter
within the meaning of the Securities Act, from and against any loss, claim,
damage or liability, joint or several, or any action in respect thereof
(including, but not limited to, any loss, claim, damage, liability or action
relating to purchases and sales of the PIES), to which the Underwriter, officer,
employee or controlling person may become subject, under the Securities Act or
otherwise, insofar as such loss, claim, damage, liability or action arises out
of, or is based upon, (i) any untrue statement or alleged untrue statement of a
material fact contained (A) in the Registration Statement, the Preliminary
Prospectus or the Final Prospectus, or in any amendment or supplement thereto,
or (B) in any blue sky application or other document prepared or executed by the
Company (or based upon any written information furnished by the Company)
specifically for the purpose of qualifying any or all of the PIES under the
securities laws of any state or other jurisdiction (any such application,
document or information being hereinafter called a "Blue Sky Application"), or
(ii) the omission or alleged omission to state in the Registration Statement,
the Preliminary Prospectus or the Final Prospectus, or in any amendment or
supplement thereto, or in any Blue Sky Application any material fact required to
be stated therein or necessary to make the statements therein not misleading,
and shall reimburse the Underwriter and each such officer, employee or
controlling person promptly upon demand for any legal or other expenses
reasonably incurred by the Underwriter, officer, employee or controlling person
in connection with investigating or defending or preparing to defend against any
such loss, claim, damage, liability or action as such expenses are incurred;
provided, however, that the Company shall not be liable under this Section 8(a)
in any such case to the extent that any such loss, claim, damage, liability or
action arises out of, or is based upon, any untrue statement or alleged untrue
statement or omission or alleged omission made in the Registration Statement,
the Preliminary Prospectus or the Final Prospectus, or in any such amendment or
supplement, or in any Blue Sky Application in reliance upon and in conformity
with written information concerning the Underwriter furnished to the Company by
or on behalf of the Underwriter specifically for inclusion therein; and provided
further that as to the Preliminary Prospectus this indemnity agreement shall not
inure to the benefit of the Underwriter, its officers or employees or any person
controlling the Underwriter on account of any loss, claim, damage, liability or
action arising from the sale of PIES to any person by the Underwriter if the
Underwriter failed to send or give a copy of the Final Prospectus to that person
within the time required by the Securities Act, and the untrue statement or
alleged untrue statement of any material fact or omission or alleged omission to
state a material fact in the Preliminary Prospectus was corrected in the Final
Prospectus, unless such failure resulted from non-compliance by the Company with
Section 5(c). The foregoing indemnity agreement is in addition to any liability
which the Company may



<PAGE>
                                                                         21


otherwise have to the Underwriter or to any officer, employee or controlling
person of the Underwriter.

     (b) The Underwriter shall indemnify and hold harmless the Company, its
officers and employees, each of its directors and each person, if any, who
controls the Company within the meaning of the Securities Act, from and against
any loss, claim, damage or liability, joint or several, or any action in respect
thereof, to which the Company or any such director, officer or controlling
person may become subject, under the Securities Act or otherwise, insofar as
such loss, claim, damage, liability or action arises out of, or is based upon,
(i) any untrue statement or alleged untrue statement of a material fact
contained (A) in the Registration Statement, the Preliminary Prospectus or the
Final Prospectus, or in any amendment or supplement thereto, or (B) in any Blue
Sky Application or (ii) the omission or alleged omission to state in the
Registration Statement, the Preliminary Prospectus or the Final Prospectus, or
in any amendment or supplement thereto, or in any Blue Sky Application any
material fact required to be stated therein or necessary to make the statements
therein not misleading, but in each case only to the extent that the untrue
statement or alleged untrue statement or omission or alleged omission was made
in reliance upon and in conformity with written information concerning the
Underwriter furnished to the Company by or on behalf of the Underwriter
specifically for inclusion therein, and shall reimburse the Company and any such
director, officer or controlling person for any legal or other expenses
reasonably incurred by the Company or any such director, officer or controlling
person in connection with investigating or defending or preparing to defend
against any such loss, claim, damage, liability or action as such expenses are
incurred. The foregoing indemnity agreement is in addition to any liability
which the Underwriter may otherwise have to the Company or any such director,
officer, employee or controlling person.

     (c) Promptly after receipt by an indemnified party under this Section 8 of
notice of any claim or the commencement of any action, the indemnified party
shall, if a claim in respect thereof is to be made against the indemnifying
party under this Section 8, notify the indemnifying party in writing of the
claim or the commencement of that action; provided, however, that the failure to
notify the indemnifying party shall not relieve it from any liability which it
may have under this Section 8 except to the extent it has been materially
prejudiced by such failure. If any such claim or action shall be brought against
an indemnified party, and it shall notify the indemnifying party thereof, the
indemnifying party shall be entitled to participate therein and, to the extent
that it wishes, jointly with any other similarly notified indemnifying party, to
assume the defense thereof with counsel reasonably satisfactory to the
indemnified party. After notice from the indemnifying party to the indemnified
party of its election to assume the defense of such claim or action, the
indemnifying party shall not be liable to the indemnified party under this
Section 8 for any legal or other expenses subsequently incurred by the
indemnified party in connection with the defense thereof other than reasonable
costs of investigation; provided, however, that the Underwriter shall have the
right to employ counsel to represent jointly the Underwriter and its officers,
employees and controlling persons who may be subject to liability arising out of
any claim in respect of which indemnity may be sought by the Underwriter against
the

<PAGE>
                                                                         22

Company under this Section 8 if, in the reasonable judgment of the
Underwriter, it is advisable for the Underwriter and its officers, employees and
controlling persons to be jointly represented by separate counsel, and in that
event the fees and expenses of such separate counsel shall be paid by the
Company. No indemnifying party shall (i) without the prior written consent of
the indemnified parties (which consent shall not be unreasonably withheld),
settle or compromise or consent to the entry of any judgment with respect to any
pending or threatened claim, action, suit or proceeding in respect of which
indemnification or contribution may be sought hereunder (whether or not the
indemnified parties are actual or potential parties to such claim or action)
unless such settlement, compromise or consent includes an unconditional release
of each indemnified party from all liability arising out of such claim, action,
suit or proceeding, or (ii) be liable for any settlement of any such action
effected without its written consent (which consent shall not be unreasonably
withheld), but if settled with the written consent of the indemnifying party or
if there be a final judgment of the plaintiff in any such action, the
indemnifying party agrees to indemnify and hold harmless any indemnified party
from and against any loss or liability by reason of such settlement or judgment.

     (d) If the indemnification provided for in this Section 8 shall for any
reason be unavailable to or insufficient to hold harmless an indemnified party
under Section 8(a) or 8(b) in respect of any loss, claim, damage or liability,
or any action in respect thereof, referred to therein, then each indemnifying
party shall, in lieu of indemnifying such indemnified party under Section 8(a)
or 8(b), as the case may be, in respect of any loss, claim damage or liability
or any action in respect thereof, referred to therein, contribute to the amount
paid or payable by such indemnified party as a result of such loss, claim,
damage or liability, or action in respect thereof referred to in Section 8(a) or
8(b), as the case may be, (i) in such proportion as shall be appropriate to
reflect the relative benefits received by the Company on the one hand and the
Underwriter on the other from the offering of the PIES 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 on the one
hand and the Underwriter on the other with respect to the statements or
omissions which resulted in such loss, claim, damage or liability, or action in
respect thereof, as well as any other relevant equitable considerations. The
relative benefits received by the Company on the one hand and the Underwriter on
the other with respect to such offering shall be deemed to be in the same
proportion as the total net proceeds from the offering of the PIES purchased
under this Agreement (before deducting expenses) received by the Company on the
one hand, and the total underwriting discounts and commissions received by the
Underwriter with respect to the PIES purchased under this Agreement, on the
other hand, bear to the total gross proceeds from the offering of the PIES under
this Agreement, in each case as set forth on the cover of the Final Prospectus.
The relative fault shall be determined by reference to whether the untrue or
alleged untrue statement of a material fact or omission or alleged omission to
state a material fact relates to information supplied by the Company or the
Underwriter, the intent of the parties and their relative knowledge, access to
information and opportunity to correct or prevent such statement or omission.
The Company and the Underwriter agree that it

<PAGE>
                                                                          23


would not be just and equitable if contributions pursuant to this Section 8(d)
were to be determined by pro rata allocation or by any other method of
allocation which does not take into account the equitable considerations
referred to in this Section 8(d). The amount paid or payable by an indemnified
party as a result of the loss, claim, damage or liability, or action in respect
thereof, referred to above in this Section 8(d) shall be deemed to include, for
purposes of this Section 8(d), 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 Section 8(d) the
Underwriter shall not be required to contribute any amount in excess of the
amount by which the total price at which the PIES underwritten by it and
distributed to the public was offered to the public exceeds the amount of any
damages which the Underwriter has otherwise paid or become liable to pay by
reason of any 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 Securities Act) shall be entitled to contribution from
any person who was not guilty of such fraudulent misrepresentation.

     (e) The Underwriter confirms and the Company acknowledges that the
statements with respect to the public offering of the PIES set forth on the
cover page of and under the caption "Underwriting" in, the Final Prospectus are
correct and constitute the only information concerning the Underwriter furnished
in writing to the Company specifically for inclusion in the Registration
Statement and the Final Prospectus.

     9. Termination. The obligations of the Underwriter hereunder may be
terminated by the Underwriter by notice given to and received by the Company
prior to delivery of any payment for the Firm PIES if, prior to that time, any
of the events described in Sections 7(l), 7(m) or 7(n) shall have occurred or if
the Underwriter shall decline to purchase the PIES for any reason permitted
under this Agreement.

     10. Notices, etc. All statements, requests, notices and agreements
hereunder shall be in writing, and:

          (a) if to the Underwriter, shall be delivered or sent by mail, telex
     or facsimile transmission to Lehman Brothers Inc., Three World Financial
     Center, New York, New York 10285, Attention: Syndicate Department (Fax:

     8(c), to the Director of Litigation, Office of the General Counsel, Lehman
     Brothers Inc., Three World Financial Center, 10th Floor, New York, New York
     10285;

     facsimile transmission to the address of the Company set forth in the
     Registration Statement, Attention: Jonathon K. Heffron, Esq. (Fax:

     11. Persons Entitled to Benefit of Agreement. This Agreement shall inure to
the benefit of and be binding upon the Underwriter, the Company, and their
respective successors and assigns. This Agreement and the terms and provisions
hereof are for the sole benefit of only those persons, except that (A) the
representations, warranties, indemnities and agreements of the Company contained
in this Agreement shall also be deemed to be for the benefit of the person or
persons, if any, who control the Underwriter within the meaning of Section 15 of
the Securities Act and (B) the indemnity agreement of the Underwriter contained
in Section 8(b) of this Agreement shall be deemed to be for the benefit of
directors of the Company and officers of the Company who have signed the
Registration Statement and any person controlling the Company within the meaning
of Section 15 of the Securities Act. Nothing in this Agreement is intended or
shall be construed to give any person, other than the persons referred to in

                               FORM OF OPINION OF
                         WACHTELL, LIPTON, ROSEN & KATZ
                    TO BE DELIVERED PURSUANT TO SECTION 7(b)

     (i) The Company has been duly incorporated and is validly existing as a
corporation in good standing under the laws of the State of Delaware.

     (ii) The Company has corporate power and authority to own, lease and
operate its properties and to conduct its business as described in the Final
Prospectus, and to enter into and perform its obligations under the Underwriting
Agreement. The activities of each of the Company's subsidiaries are permitted to
subsidiaries of a savings and loan holding company.

     (iii) The Bank is the only "significant subsidiary" of the Company (as such
term is defined in Rule 1-02 of Regulation S-X). The only subsidiaries of the
Company other than the Bank are the wholly-owned subsidiaries of the Bank listed
on Schedule 1 to the Underwriting Agreement which, considered in the aggregate
as a single subsidiary, do not constitute a "significant subsidiary" as defined
in Rule 1-02 of Regulation S-X.

     (iv) The Company has an authorized capitalization as set forth in the Final
Prospectus. The shares of issued and outstanding capital stock of the Company,
including the shares of Preferred Stock being delivered on such Delivery Date,
have been duly authorized and validly issued and are fully paid and
non-assessable; and none of the outstanding shares of capital stock of the
Company, including the shares of Preferred Stock being delivered on such
Delivery Date, was issued in violation of any preemptive or other similar rights
of any securityholder of the Company.

     (v) The Underwriting Agreement has been duly authorized, executed
and delivered by the Company.

     (vi) The unissued shares of Common Stock to be issued and sold by the
Company pursuant to the Purchase Contracts have been duly and validly authorized
and reserved for issuance and when issued and delivered in accordance with the
provisions of the Purchase Contracts, will be duly and validly issued, fully
paid and non-assessable.

     (vii) The Corporate PIES have been duly authorized, executed and
delivered by the Company and (assuming due execution by the Purchase Contract
Agent as attorney-in-fact of the holders thereof and due authentication by the
Purchase Contract Agent) upon payment therefor as set forth in the Underwriting
Agreement, will be duly and validly issued and outstanding, and will constitute
valid and binding obligations of the Company entitled to the benefits of the
Purchase Contract Agreement and enforceable against the Company in accordance
with their terms, except as enforceability may be limited by the Bankruptcy
Exceptions and an implied covenant of good faith and fair dealing.

<PAGE>


     (viii) The Purchase Contract Agreement and the Pledge Agreement have been
duly authorized, executed and delivered by the Company and (assuming due
execution and delivery by the Purchase Contract Agent and, in the case of the
Pledge Agreement, the Securities Intermediary and the Collateral Agent)
constitute valid and binding agreements of the Company enforceable against the
Company in accordance with their respective terms, except as the enforceability
thereof may be limited by the Bankruptcy Exceptions and an implied covenant of
good faith and fair dealing. While the matter is not free from doubt, if a
Termination Event occurs by reason of the Company's becoming a debtor in a case
under the Bankruptcy Code, Section 365(e)(1) of the Bankruptcy Code should not
deprive the Purchase Contract Agent of the substantive benefit of the provisions
of Sections 3.15 and 5.8 of the Purchase Contract Agreement and Section 5.4 of
the Pledge Agreement that require termination of the Purchase Contracts and
release of the Collateral Agent's security interest in the Pledged Shares and
Pledged Treasury Securities; provided, however, that exercise of the rights
afforded to the Purchase Contract Agent under such provisions may require relief
from the automatic stay arising in such Bankruptcy Code case.

     (ix) The Remarketing Agreement has been duly authorized, executed and
delivered by the Company.

     (x) The provisions of the Pledge Agreement are effective to create,
in favor of the Collateral Agent for the benefit of the Company, a valid and
perfected security interest under the Uniform Commercial Code as in effect on
the date of such opinion in the State of New York (the "New York UCC") in the
Pledged Preferred Stock and under applicable regulation of the United States
Treasury as in effect on such date in the Pledged Treasury Securities from time
to time credited to the Collateral Account in accordance with the Pledge
Agreement. For purposes of such counsel's opinion, capitalized terms used in
this clause (x) shall have the meanings ascribed to such terms in the Pledge
Agreement.

     (xi) There are no preemptive or other rights to subscribe for or to
purchase, nor any restriction upon the voting or transfer of, (A) any shares of
Common Stock issuable pursuant to the Purchase Contracts or (B) the Preferred
Stock pursuant to the Company's charter, by-laws, the certificate of designation
relating to the Preferred Stock or any agreement or other instrument known to
such counsel.

     (xii) The Registration Statement has been declared effective under the
Securities Act; the Final Prospectus was filed with the Commission pursuant to
Rule 424(b) in the manner and within the time period required by Rule 424(b);
and, to the best of our knowledge, no stop order suspending the effectiveness of
the Registration Statement has been issued under the Securities Act and no
proceedings for that purpose have been instituted or are pending or threatened
by the Commission.

     (xiii) The Registration Statements, the Final Prospectus, and each
amendment or supplement to the Registration Statement and the Final Prospectus,
as of their respective effective or issue dates (other than the financial
statements and supporting schedules included therein or omitted therefrom, as to
which we express no opinion) complied as to form in all material respects with
the requirements of the Securities Act and the Rules and Regulations.

<PAGE>


     (xiv) The statements contained in the Final Prospectus under the
captions (A) "Description of Offered Securities," in the Basic Prospectus and
(B) "Prospectus Supplement Summary--The Offering," "Description of the PIES,"
"Description of the Purchase Contracts," "Certain Provisions of the Purchase
Contracts, the Purchase Contract Agreement and the Pledge Agreement," and
"Description of the Preferred Stock" in the Prospectus Supplement insofar as
they purport to constitute summaries of certain terms of documents referred to
therein, constitute accurate summaries of the terms of such documents in all
material respects.

     (xv) The statements set forth in the Final Prospectus under the
caption "United States Federal Income Tax Consequences" insofar as they purport
to constitute summaries of matters of United States federal tax laws and
regulations or legal conclusions with respect thereto, constitute accurate
summaries of the matters described therein in all material respects.

     (xvi) To the best of our knowledge, there are no statutes or regulations
that are required to be described in the Final Prospectus that are not described
as required.

     (xvii) Neither the Company, the Bank nor any of their respective
subsidiaries is in violation of its charter or by-laws and, to the best of our
knowledge, no default by the Company, the Bank or any of their respective
subsidiaries exists in the due performance or observance of any material
obligation, agreement, covenant or condition contained in any contract,
indenture, mortgage, loan agreement, note, lease or other agreement or
instrument that is described or referred to in the Registration Statement or the
Final Prospectus or filed as an exhibit to the Registration Statement.

     (xviii) No filing with, or authorization, approval, consent, license,
order, registration, qualification or decree of, any court or governmental
authority or agency, domestic or foreign including, without limitation, the OTS
and FDIC (other than under the Securities Act and the Rules and Regulations,
which have been obtained, or as may be required under the securities or blue sky
laws of the various states, as to which we express no opinion) is necessary or
required in connection with the due authorization, execution and delivery of the
Underwriting Agreement, the offering, issuance, sale or delivery of the PIES,
the performance of the Transactions, or the performance by the Company of its
obligations pursuant to the Underwriting Agreement, the Purchase Contract
Agreements, the Pledge Agreement, the Remarketing Agreement, the Purchase
Contracts, the Preferred Stock or the PIES.

     (xix) The execution, delivery and performance of the Underwriting
Agreement, the Purchase Contract Agreement, the Pledge Agreement and the
Remarketing Agreement, and the consummation by the Company of the Transactions
contemplated thereby and in the Registration Statement have been duly authorized
by all necessary corporate action and do not and will not result in any
violation of the provisions of the charter or by-laws of the Company or any of
its subsidiaries, or any applicable law, statute, rule, regulation, judgment,
order, writ or decree, known to us, of any government, governmental
instrumentality or court, domestic or foreign, having jurisdiction over the
Company.

     (xx) To the best of our knowledge, there are no persons with registration
rights or other similar rights to have any securities registered pursuant to the
Registration Statement or otherwise registered by the Company under the
Securities Act, except as described in the

<PAGE>


Registration Statement or as set forth in any agreement described therein as
containing such rights.

     (xxi) The Company is not, and upon the sale of the PIES as contemplated in
the Underwriting Agreement and the application of the net proceeds therefrom as
described in the Final Prospectus will not be, an "investment company" or an
entity "controlled" by an "investment company," as such terms are defined in the
1940 Act.

     Nothing has come to our attention that would lead us to believe that the
Registration Statement or any amendment thereto (except for financial statements
and schedules and other financial data included therein or omitted therefrom, as
to which we make no statement), at the time such Registration Statement or any
such amendment became effective, contained an untrue statement of a material
fact or omitted to state a material fact required to be stated therein or
necessary to make the statements therein not misleading or that the Final
Prospectus or any amendment or supplement thereto (except for financial
statements and schedules and other financial data included therein or omitted
therefrom, as to which we make no statement), at the time the Final Prospectus
was issued, at the time any such amended or supplemented Final Prospectus was
issued or at the Closing Date, included or includes an untrue statement of a
material fact or omitted or omits to state a material fact necessary in order to
make the statements therein, in the light of the circumstances under which they
were made, not misleading.

     In rendering such opinion, such counsel may rely as to matters of fact (but
not as to legal conclusions), to the extent they deem proper, on certificates of
responsible officers of the Company and public officials. Such opinion shall not
state that it is to be governed or qualified by, or that it is otherwise subject
to, any treatise, written policy or other document relating to legal opinions,
including, without limitation, the Legal Opinion Accord of the ABA Section of
Business Law (1991). All terms used but not defined in this exhibit should have
the meanings ascribed to them in the Underwriting Agreement and should be
defined accordingly in the form of opinion to be delivered.

                                                                 Exhibit B

                               FORM OF OPINION OF
                               JONATHON K. HEFFRON
                         GENERAL COUNSEL OF THE COMPANY,
                    TO BE DELIVERED PURSUANT TO SECTION 7(c)

     (i) The Company has been duly incorporated and is validly existing as a
corporation in good standing under the laws of the State of Delaware.

     (ii) The Company has corporate power and authority to own, lease and
operate its properties and to conduct its business as described in the Final
Prospectus, and to enter into and perform its obligations under the Underwriting
Agreement. The activities of each of the Company's subsidiaries are permitted to
subsidiaries of a savings and loan company.

     (iii) The Bank is the only "significant subsidiary" of the Company (as such
term is defined in Rule 1-02 of Regulation S-X). The only subsidiaries of the
Company other than the Bank are the wholly-owned subsidiaries of the Bank listed
on Schedule 1 to the Underwriting Agreement, which, considered in the aggregate
as a single subsidiary, do not constitute a "significant subsidiary" as defined
in Rule 1-02 of Regulation S-X. The activities of all of the Bank's subsidiaries
are permitted to subsidiaries of a federally chartered savings bank, the
deposits of which are insured by the SAIF, which is administered by the FDIC.

     (iv) The Bank is a federally chartered stock savings bank, duly
incorporated and validly existing under the laws of the United States, and the
Bank's charter is in full force and effect. The Bank is a member of the Federal
Home Loan Bank of Dallas and has been duly issued a certificate stating that its
savings accounts are insured by the FDIC in accordance with applicable law, and
no proceedings for the termination or revocation of such membership or insurance
are pending or, to the best of my knowledge, threatened.

     (v) The Bank has corporate power and authority to own, lease and operate
its properties and to conduct its business as described in the Final Prospectus.

     (vi) Each subsidiary of the Bank has been duly organized and is validly
existing as a corporation in good standing under the laws of the jurisdiction of
its incorporation and has the power and authority to own, lease and operate its
properties and to conduct its business as described in the Final Prospectus. The
activities described in the Final Prospectus of each of the Bank's subsidiaries
are permitted activities of subsidiaries of a federally chartered savings bank,
the deposits of which are insured by the SAIF, which is administered by the
FDIC.

     (vii) The Company, the Bank and each subsidiary of the Company or the Bank
is duly qualified as a foreign corporation to transact business and is in good
standing in each jurisdiction in which such qualification is required, whether
by reason of the ownership or leasing of property or the conduct of business,
except where the failure so to qualify or to be in good standing would not
result in a Material Adverse Effect.

     (viii) All of the issued and outstanding capital stock of the Bank and each
subsidiary of the Bank has been duly authorized and validly issued, is fully
paid and non-assessable and,

<PAGE>


except as otherwise disclosed in the Registration Statement, is owned by the
Company, directly or through subsidiaries, to the best of my knowledge, free and
clear of any security interest, mortgage, pledge, lien, encumbrance, claim or
equity; none of the outstanding shares of capital stock of any subsidiary was
issued in violation of the preemptive or similar rights of any securityholder of
such subsidiary.

     (ix) The Company has an authorized capitalization as set forth in the Final
Prospectus. The shares of issued and outstanding capital stock of the Company,
including the shares of Preferred Stock being delivered on such Delivery Date,
have been duly authorized and validly issued and are fully paid and
non-assessable; and none of the outstanding shares of capital stock of the
Company, including the shares of Preferred Stock being delivered on such
Delivery Date, was issued in violation of any preemptive or other similar rights
of any securityholder of the Company.

     (x) The documents incorporated by reference in the Final Prospectus and any
further amendment or supplement to any such incorporated document made by the
Company prior to the Closing Date (other than the financial statements and
related schedules contained therein, as to which such counsel need express no
opinion), when they became effective or were filed with the Commission, as the
case may be, complied as to form in all material respects with the requirements
of the Securities Act or the Exchange Act, as applicable, and the rules and
regulations of the Commission thereunder.

     (xi) There is not pending or, to my knowledge, threatened any action, suit,
proceeding, inquiry or investigation, to which the Company or the Bank or any of
their respective subsidiaries is a party, or to which the property of the
Company or the Bank or any of their respective subsidiaries is subject, before
or brought by any court or governmental agency or body, domestic or foreign,
which might reasonably be expected to result in a Material Adverse Effect, or
which might reasonably be expected to materially and adversely affect the
properties or assets thereof or the consummation of the transactions
contemplated in the Underwriting Agreement or the performance by the Company of
its obligations thereunder. The aggregate of all pending legal or governmental
proceedings to which the Company, the Bank, or any of their respective
subsidiaries is known by me to be a party or of which any of their respective
property or assets is the subject which are not described in the Registration
Statement, including ordinary routine litigation incidental to the business,
could not reasonably be expected to result in a Material Adverse Effect. To the
best of my knowledge, neither the Company nor any of its subsidiaries is a party
to any written agreement or memorandum of understanding with, or commitment
letter or similar undertaking to, or subject to any order or directive issued
by, or a recipient of any extraordinary supervisory letter from, or has adopted
any board resolutions at the request of, any federal or state government agency
or authority with responsibility for the supervision or regulation of depository
institutions or their holding companies or the insurance of deposits, which in
any such case materially restricts the conduct of its business or in any manner
relates to its capital adequacy, its credit policies or its management, nor has
the Company or any of its subsidiaries been advised by any such regulatory
authority that it is contemplating issuing or requesting any such order, decree,
written agreement, memorandum of understanding, extraordinary supervisory
letter, commitment letter or similar undertakings or board resolutions. No labor
dispute with the employees of the Company or any subsidiary exists or, to the
knowledge of the Company, is imminent, and the Company is not aware of any
existing or imminent labor disturbance by the employees of any of its or any
subsidiary's principal suppliers,

<PAGE>


manufacturers, customers or contractors, which, in either case, may reasonably
be expected to result in a Material Adverse Effect.

     (xii) To the best of my knowledge, there are no statutes or regulations
that are required to be described in the Final Prospectus that are not described
as required.

     (xiii) All descriptions in the Registration Statement of contracts and
other documents to which the Company or its subsidiaries are a party are
accurate in all material respects; to the best of my knowledge, there are no
franchises, contracts, indentures, mortgages, loan agreements, notes, leases or
other instruments required to be described or referred to in the Registration
Statement or to be filed as exhibits thereto other than those described or
referred to therein or filed or incorporated by reference as exhibits thereto,
and the descriptions thereof or references thereto are correct in all material
respects.

     (xiv) Neither the Company, the Bank nor any of their respective
subsidiaries is in violation of its charter or by-laws and no default by the
Company, the Bank or any of their respective subsidiaries exists in the due
performance or observance of any material obligation, agreement, covenant or
condition contained in any contract, indenture, mortgage, loan agreement, note,
lease or other agreement or instrument that is described or referred to in the
Registration Statement or the Final Prospectus or filed as an exhibit to the
Registration Statement.

     (xv) The execution, delivery and performance of the Underwriting Agreement,
the Purchase Contract Agreement, the Pledge Agreement and the Remarketing
Agreement, and the consummation by the Company of the Transactions contemplated
thereby and in the Registration Statement has been duly authorized by all
necessary corporate action and do not and will not, whether with or without the
giving of notice or lapse of time or both, conflict with or constitute a breach
of, or default or Repayment Event (as defined in Section l(p) of the
Underwriting Agreement) under or result in the creation or imposition of any
lien, charge or encumbrance upon any property or assets of the Company or any
subsidiary pursuant to any contract, indenture, mortgage, deed of trust, loan or
credit agreement, note, lease or any other agreement or instrument, known to me,
to which the Company or any subsidiary is a party or by which it or any of them
may be bound, or to which any of the property or assets of the Company, the Bank
or any of their respective subsidiaries is subject (except for such conflicts,
breaches or defaults or liens, charges or encumbrances that would not result in
a Material Adverse Effect), nor will such action result in any violation of the
provisions of the charter or by-laws of the Company, the Bank or any of their
respective subsidiaries, or any applicable law, statute, rule, regulation,
judgment, order, writ or decree, known to me, of any government, governmental
instrumentality or court, domestic or foreign, having jurisdiction over the
Company, the Bank, or any of their respective subsidiaries or any of their
respective properties, assets or operations.

     (xvi) There are no persons with registration rights or other similar rights
to have any securities registered pursuant to the Registration Statement or
otherwise registered by the Company or the Bank under the Securities Act, except
as described in Registration Statement or as set forth in any agreement
described therein as containing such rights.

     (xvii) The Company, the Bank and each of its subsidiaries possess such
Governmental Licenses issued by the appropriate federal, state, local or foreign
regulatory agencies or bodies

<PAGE>

necessary to conduct the business now operated by them; the Company, the Bank
and each of its subsidiaries are in compliance with the terms and conditions of
all such Governmental Licenses, except where the failure so to comply would not,
singly or in the aggregate, have a Material Adverse Effect; all of the
Governmental Licenses are valid and in full force and effect, except when the
invalidity of such Governmental Licenses or the failure of such Governmental
Licenses to be in full force and effect would not have a Material Adverse
Effect; and neither the Company, the Bank nor any of their respective
subsidiaries has received any notice of proceedings relating to the revocation
or modification of any such Governmental Licenses which, singly or in the
aggregate, if the subject of an unfavorable decision, ruling or finding, would
result in a Material Adverse Effect.

     (xviii) The Company, the Bank and each of their respective subsidiaries
have good and marketable title to all real, tangible and intangible property
reflected in the most recent balance sheet included in the Final Prospectus as
owned by the Company, the Bank and its subsidiaries and good title to all other
properties reflected in the most recent balance sheet included in the Final
Prospectus as owned by them, in each case, free and clear of all mortgages,
pledges, liens, security interests, claims, restrictions or encumbrances of any
kind except such as (A) are described in the Final Prospectus or (a) do not,
singly or in the aggregate, materially affect the value of such property and do
not interfere with the use made and proposed to be made of such property by the
Company, the Bank or any of their respective subsidiaries; or, with respect to
any such real property, render title unmarketable as to a material part thereof
and all of the leases and subleases material to the business of the Company, the
Bank and of their respective subsidiaries, considered as one enterprise, and
under which the Company, the Bank or any of their respective subsidiaries holds
properties described in the Final Prospectus, are in full force and effect, and
neither the Company, the Bank nor any of their respective subsidiaries has any
notice of any material claim of any sort that has been asserted by anyone
adverse to the rights of the Company, the Bank or any of their respective
subsidiaries under any of the leases or subleases mentioned above, or affecting
or questioning the rights of the Company, the Bank or such subsidiary to the
continued possession of the leased or subleased premises under any such lease or
sublease.

     (xix) Except as described in the Registration Statement or except as would
not, singly or in the aggregate, result in a Material Adverse Effect, (A) the
Company, the Bank and each of their respective subsidiaries is not in violation
of any Environmental Laws, (B) the Company, the Bank and each of their
respective subsidiaries have all permits, authorizations and approvals required
under any applicable Environmental Laws and are each in compliance with their
requirements, (C) there are no pending or, to the knowledge of the Company,
threatened administrative, regulatory or judicial actions, suits, demands,
demand letters, claims, liens, notices of noncompliance or violation,
investigation or proceedings relating to any Environmental Law against the
Company, the Bank or any of their respective subsidiaries and (D) to the
knowledge of the Company there are no events or circumstances that might
reasonably be expected to form the basis of an order for clean-up or
remediation, or an action, suit or proceeding by any private party or
governmental body or agency, against or affecting the Company, the Bank or any
of their respective subsidiaries relating to Hazardous Materials or any
Environmental Laws.

     (xx) In the event the Company shall become either directly or indirectly a
bank holding company for purposes of the BHC Act and the BHC Rules, the current
activities of the Company

<PAGE>

and its subsidiaries (as defined in the BHc Rules) would be activities
permissible for a bank holding company under the BHC Act and the BHC Rules.

     (xxi) No filing with, or authorization, approval, consent, license, order,
registration, qualification or decree of, any court or governmental authority or
agency, domestic or foreign including, without limitation, the OTS and FDIC is
necessary or required by federal banking laws and regulations in connection with
the due authorization, execution and delivery of the Underwriting Agreement, the
offering, issuance, sale or delivery of the PIES, the performance of the
Transactions, or the performance by the Company of its obligations pursuant to
the Underwriting Agreement, the Purchase Contract Agreements, the Pledge
Agreement, the Remarketing Agreement, the Purchase Contracts, the Preferred
Stock or the PIES.

     Nothing has come to my attention that would lead me to believe that the
Registration Statement or any amendment thereto, including the information
included in any prospectus that was omitted from such Registration Statement at
the time it became effective but that is deemed to be part of such Registration
Statement at the time it became effective (except for financial statements and
schedules and other financial data included therein or omitted therefrom, as to
which I make no statement), at the time such Registration Statement or any such
amendment became effective, contained an untrue statement of a material fact or
omitted to state a material fact required to be stated therein or necessary to
make the statements therein not misleading or that the Final Prospectus or any
amendment or supplement thereto (except for financial statements and schedules
and other financial data included therein or omitted therefrom, as to which I
make no statement), at the time the Final Prospectus was issued, at the time any
such amended or supplemented Final Prospectus was issued or at either Delivery
Date, included or includes an untrue statement of a material fact or omitted or
omits to state a material fact necessary in order to make the statements
therein, in the light of the circumstances under which they were made, not
misleading.

     In rendering such opinion, such counsel may rely as to matters of fact (but
not as to legal conclusions), to the extent they deem proper, on certificates of
responsible officers of the Company and public officials. Such opinion shall not
state that it is to be governed or qualified by, or that it is otherwise subject
to, any treatise, written policy or other document relating to legal opinions,
including, without limitation, the Legal Opinion Accord of the ABA Section of
Business Law (1991). All terms used but not defined in this exhibit should have
the meanings ascribed to them in the Underwriting Agreement and should be
defined accordingly in the form of opinion to be delivered.

            (c) The accountants  who certified the financial  statements and any
      supporting  schedules thereto included or incorporated by reference in the

      public  accountants  as required by the  Securities  Act and the Rules and
      Regulations.

      schedules  and  notes,   present  fairly  in  all  material  respects  the

      in stockholders' equity and cash flows of the Company and its consolidated
      subsidiaries  for the periods  specified;  said financial  statements have

      summary  financial  information  included in the Final Prospectus  present
      fairly in all material  respects the  information  shown  therein and have
      been  compiled on a basis  consistent  with that of the audited  financial
      statements included in the Registration Statement.

            (e) Since the respective  dates as of which  information is given in
      the Registration  Statement and the Final Prospectus,  except as otherwise
      stated  therein,  (i) there  has been no  material  adverse  change in the
      earnings,  stockholders' equity, business affairs or business prospects of
      the Company and its subsidiaries considered as one enterprise,  whether or
      not arising in the ordinary  course of  business,  (ii) there have been no
      transactions entered into by the Company or any of its subsidiaries, other
      than those in the  ordinary  course of business,  which are material  with
      respect to the Company and its subsidiaries  considered as one enterprise,
      and (iii)  except for regular  quarterly  dividends on the common stock of
      the Company or on the Series A Preferred Stock of Bank United (the "Bank")

      made by the Bank or the Company on any class of its capital stock.

      federal  savings bank, as the case may be, in good standing under the laws

      as a foreign  corporation to transact  business and is in good standing in
      each other jurisdiction in which such  qualification is required,  whether
      by reason of the  ownership  or  leasing  of  property  or the  conduct of
      business, except where the failure so to qualify or to be in good standing
      would not have a material  adverse  effect on the  consolidated  financial
      position,   stockholders'  equity,

<PAGE>
                                                                          4

     subsidiaries considered as one enterprise (a "Material Adverse Effect").

            (g) (i) The Bank is the only "significant subsidiary" of the Company
      (as  such  term is  defined  in Rule  1-02 of  Regulation  S-X).  The only
      subsidiaries  of the  Company  other  than the  Bank are the  wholly-owned
      subsidiaries of the Bank listed on Schedule 1 hereto which,  considered in
      the aggregate as a single  subsidiary,  do not  constitute a  "significant
      subsidiary"  as defined in Rule 1-02 of Regulation  S-X. The activities of
      all  of  the  Bank's  subsidiaries  are  permitted  to  subsidiaries  of a
      federally chartered savings bank, the deposits of which are insured by the

      and each  subsidiary  of the Bank has been  duly  authorized  and  validly
      issued,  is  fully  paid  and  non-assessable  and,  except  as  otherwise
      disclosed in the Final  Prospectus,  and other than the Series A Preferred
      Stock of the Bank and the Series B Preferred  Stock of the Bank,  is owned
      by the Company,  directly or through  subsidiaries,  free and clear of any
      security interest,  mortgage, pledge, lien, encumbrance,  claim or equity;
      none of the  outstanding  shares of capital  stock of any  subsidiary  was
      issued  in  violation  of  the   preemptive  or  similar   rights  of  any
      securityholder of such subsidiary.

            (h) The  authorized,  issued and  outstanding  capital  stock of the
      Company  is as set  forth  in  the  Final  Prospectus  under  the  caption
      "Capitalization"  (except for subsequent  issuances,  if any,  pursuant to
      reservations,  agreements  or employee  benefit  plans  referred to in the
      Final Prospectus). The shares of issued and outstanding capital stock have
      been  duly   authorized   and  validly  issued  and  are  fully  paid  and
      non-assessable; none of the outstanding shares of capital stock was issued
      in  violation  of  the   preemptive  or  other   similar   rights  of  any
      securityholder of the Company.

            (i) This Agreement has been duly authorized,  executed and delivered
      by the Company.

            (j) The Stock has been duly  authorized  by the  Company  and,  when
      issued and delivered against payment therefor as provided herein,  will be
      duly and validly issued,  fully paid and non-assessable and not subject to
      the  preemptive  or other  similar  rights  of any  person;  and the Stock
      conforms  to all  statements  relating  thereto  contained  in  the  Final
      Prospectus  and such  description  conforms to the rights set forth in the
      instruments defining the same.

            (k) Neither the Company nor any of its  subsidiaries  has  sustained
      since the date of the latest  audited  financial  statements  included  or
      incorporated by reference in the Final Prospectus any 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  or as would  not  result  in a  Material
      Adverse  Effect;  and,  since  such date  there

<PAGE>
                                                                          5


     has not been any material  change in the capital stock 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,  otherwise  than as set  forth or  contemplated  in the Final
     Prospectus.

          (l) Neither the Company nor any of its subsidiaries is in violation of
     its charter or by-laws or in default in the  performance  or  observance of
     any obligation, agreement, covenant or condition contained in any contract,
     indenture,  mortgage, deed of trust, loan or credit agreement,  note, lease
     or other  agreement  or  instrument  to  which  the  Company  or any of its
     subsidiaries  is a party or by which it or any of them may be bound,  or to
     which any of the assets,  properties or operations of the Company or any of
     its subsidiaries is subject  (collectively,  "Agreements and Instruments"),
     except  for such  defaults  that  would not  result in a  Material  Adverse
     Effect;  and the execution,  delivery and performance of this Agreement and
     the consummation of the transactions  contemplated hereby and compliance by
     the Company with its obligations hereunder have been duly authorized by all
     necessary corporate action and do not and will not, whether with or without
     the  giving  of  notice  or  passage  of time  or  both,  conflict  with or
     constitute  a breach of, or default or Repayment  Event (as defined  below)
     under,  or result in the  creation  or  imposition  of any lien,  charge or
     encumbrance upon any assets, properties or operations of the Company or any
     of its subsidiaries pursuant to, any Agreements and Instruments (except for
     such conflicts, breaches or defaults or liens, charges or encumbrances that
     would not result in a Material Adverse Effect), nor will such action result
     in any violation of the provisions of the charter or by-laws of the Company
     or any of its  subsidiaries  or (except for such  violations that would not
     result in a Material  Adverse  Effect) any applicable law,  statute,  rule,
     regulation,  judgment, order, writ or decree of any government,  government
     instrumentality or court, domestic or foreign, having jurisdiction over the
     Company or any of its  subsidiaries  or any of their assets,  properties or
     operations.  As used  herein,  a  "Repayment  Event"  means  any  event  or
     condition  which gives the holder of any note,  debenture or other evidence
     of indebtedness (or any person acting on such holder's behalf) the right to
     require (whether with or without the giving of notice or passage of time or
     both) the  repurchase,  redemption or repayment of all or a portion of such
     indebtedness by the Company or any of its subsidiaries.

          (m)  No  labor  dispute  with  the  employees  of the  Company  or any
     subsidiary exists or, to the knowledge of the Company, is imminent, and the
     Company is not aware of any existing or imminent  labor  disturbance by the
     employees  of  any  of  its  or  any  subsidiary's   principal   suppliers,
     manufacturers,  customers  or  contractors,  which,  in  either  case,  may
     reasonably be expected to result in a Material Adverse Effect.

          (n) There is no action,  suit,  proceeding,  inquiry or  investigation
     before or brought by any court or governmental  agency or body, domestic or
     foreign,  now pending,  or, to the  knowledge  of the Company,  threatened,
     against  or  affecting  the  Company  or  any of  its  subsidiaries,  which
     individually or in the aggregate for all such actions, suits,

     Registration  Statement (other than as disclosed  therein),  or which might
     reasonably  be expected to result in a Material  Adverse  Effect,  or which
     might  reasonably  be  expected  to  materially  and  adversely  affect the
     consummation  of the  transactions  contemplated  by this  Agreement or the
     performance by the Company of its obligations  hereunder;  the aggregate of
     all pending legal or  governmental  proceedings to which the Company or any
     of its subsidiaries is a party or of which any of their respective property
     or  assets  is the  subject  which are not  described  in the  Registration
     Statement, including ordinary routine litigation incidental to the business
     of the Company or any of its subsidiaries, could not reasonably be expected
     to result in a Material Adverse Effect.  Neither the Company nor any of its
     subsidiaries  is  a  party  to  any  written  agreement  or  memorandum  of
     understanding  with, or  commitment  letter or similar  undertaking  to, or
     subject  to any  order  or  directive  issued  by,  or a  recipient  of any
     extraordinary supervisory letter from, or has adopted any board resolutions
     at the request of, any federal or state government agency or authority with
     responsibility for the supervision or regulation of depository institutions
     or their holding companies or the insurance of deposits,  which in any such
     case  materially  restricts  the  conduct of its  business or in any manner
     relates to its capital adequacy, its credit policies or its management, nor
     has  the  Company  or any of its  subsidiaries  been  advised  by any  such
     regulatory  authority  that it is  contemplating  issuing or requesting any
     such  order,  decree,  written  agreement,   memorandum  of  understanding,
     extraordinary supervisory letter, commitment letter or similar undertakings
     or board  resolutions.

          (o) There are no  contracts  or  documents  which are  required  to be
     described  in the  Registration  Statement,  the  Final  Prospectus  or the
     documents  incorporated  by  reference  therein or to be filed as  exhibits
     thereto which have not been so described and filed as required.

          (p) The Company and its subsidiaries own or possess, or can acquire on
     reasonable terms, adequate patents,  patent rights,  licenses,  inventions,
     copyrights,  know-how  (including trade secrets and other unpatented and/or
     unpatentable   proprietary   or   confidential   information,   systems  or
     procedures),  trademarks,  service marks, trade names or other intellectual
     property (collectively,  "Intellectual Property") necessary to carry on the
     business  now  operated  by them,  and  neither  the Company nor any of its
     subsidiaries  has  received  any  notice  or  is  otherwise  aware  of  any
     infringement  of or conflict with asserted rights of others with respect to
     any  Intellectual  Property  or of any facts or  circumstances  which would
     render any  Intellectual  Property  invalid or  inadequate  to protect  the
     interest  of the  Company  or any of its  subsidiaries  therein,  and which
     infringement  or  conflict  (if the  subject of any  unfavorable  decision,
     ruling or finding) or invalidity or inadequacy, singly or in the aggregate,
     would result in a Material Adverse Effect.

          (q) No filing with,  or  authorization,  approval,  consent,  license,
     order, registration,  qualification or decree of, any court or governmental
     authority or agency,  including,  without limitation,  the Office of Thrift
     Supervision  (the "OTS") and the FDIC,  is

     necessary or required for the performance by the Company of its obligations
     hereunder in connection  with the offering or sale of the Stock  hereunder,
     for the  consummation of the  transactions  contemplated  hereby or for the
     other transactions described in the Registration Statement,  except such as
     have been already  obtained or will have been obtained or made prior to the
     Closing Date (as defined  below) or as may be required under the Securities
     Act or the Rules and Regulations or state securities laws.

            (r) The Company and its subsidiaries possess such permits, licenses,
      approvals, consents and other authorizations (collectively,  "Governmental
      Licenses")  issued by the  appropriate  federal,  state,  local or foreign
      regulatory  agencies  or bodies  necessary  to conduct  the  business  now
      operated by them; the Company and its  subsidiaries are in compliance with
      the terms and conditions of all such Governmental  Licenses,  except where
      the failure so to comply  would not,  singly or in the  aggregate,  have a
      Material Adverse Effect; all of the Governmental Licenses are valid and in
      full force and effect,  except when the  invalidity  of such  Governmental
      Licenses or the failure of such Governmental  Licenses to be in full force
      and effect  would not have a Material  Adverse  Effect;  and  neither  the
      Company nor any of its subsidiaries has received any notice of proceedings
      relating  to the  revocation  or  modification  of any  such  Governmental
      Licenses  which,  singly  or  in  the  aggregate,  if  the  subject  of an
      unfavorable  decision,  ruling or  finding,  would  result  in a  Material
      Adverse Effect.

            (s) The Company and its subsidiaries  have good and marketable title
      to all real, tangible and intangible property reflected in the most recent
      balance sheet included in the Final Prospectus as owned by the Company and
      its subsidiaries  and good title to all other properties  reflected in the
      most recent  balance  sheet  included in the Final  Prospectus as owned by

      "initial  letters"),  the Company shall have furnished to the  Underwriter
      letters (the "bring-down  letters") of such accountants,  addressed to the
      Underwriter  and dated as of such Delivery Date confirming in all material
      respects the conclusions and findings set forth in the initial letters.

            (i)  The  Company   shall  have   furnished  to  the   Underwriter a
      certificate, dated such Delivery Date, of its Chairman of the Board or its
      President and its chief financial officer stating that:

                 (i)   The  representations,  warranties  and  agreements of the
            Company in Section 1 are true and correct as of such Delivery  Date;
            the Company has complied with all its agreements  contained  herein;
            and the conditions set forth in Section 7(a) have been fulfilled;

                 (ii)  They have carefully  examined the  Registration Statement
            and the Final  Prospectus and, in their opinion (A) the Registration
            Statement and the Final  Prospectus,  as of such Delivery  Date, did
            not include any untrue statement of a material fact and did not omit
            to  state  any  material  fact  required  to be  stated  therein  or
            necessary to make the  statements  therein not  misleading,  and (B)
            since the date of this Agreement, no event has occurred which should
            have been set forth in a supplement or amendment to the Registration
            Statement or the Final Prospectus.

           (j) On the Delivery Date, counsel for the Underwriter shall have been
      furnished  with such  documents  as they may  require  for the  purpose of
      enabling  them to pass upon the  issuance  and sale of the Stock as herein
      contemplated,  or other legal matters incident to the authorization,  form
      and validity of this Agreement, the Stock, the Registration

     Statement,  the Preliminary Prospectus and the Final Prospectus or in order
     to evidence the accuracy of any of the  representations  or warranties,  or
     the  fulfillment  of any of  the  conditions,  herein  contained,  and  all
     proceedings  taken by the Company in connection  with the issuance and sale
     of the  Stock as  herein  contemplated  shall be  satisfactory  in form and
     substance to the Underwriter and counsel for the Underwriter.

           (k) There  shall not have  been, since the date  hereof or since the
      respective dates as of which information is given in the Final Prospectus,
      any material adverse change in the condition,  financial or otherwise,  or
      in the consolidated  financial position,  stockholders' equity, results of
      operations,  business or  prospects  of the  Company and its  subsidiaries
      considered  as one  enterprise,  whether or not  arising  in the  ordinary
      course of business.

           (l) Subsequent to the execution and delivery of this Agreement (i) no
      downgrading  shall have  occurred in the rating  accorded the Company's or
      any  significant  subsidiary's  debt  securities or preferred stock by any
      "nationally recognized  statistical rating organization",  as that term is
      defined by the  Commission for purposes of Rule 436(g)(2) of the Rules and
      Regulations 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  or any  significant
      subsidiary's debt securities or preferred stock.

           (m)  Subsequent to the execution and delivery of this Agreement there
      shall not have  occurred any of the  following:  (i) trading in securities
      generally on the New York Stock Exchange or the American Stock Exchange or
      in the  over-the-counter  market,  or  trading  in any  securities  of the
      Company on any exchange or in the over-the-counter market, shall have been
      suspended  or  minimum  prices  shall  have been  established  on any such
      exchange  or such  market by the  Commission,  by such  exchange or by any
      other regulatory body or governmental authority having jurisdiction,  (ii)
      a  banking  moratorium  shall  have  been  declared  by  Federal  or state
      authorities,  (iii)  the  United  States  shall  have  become  engaged  in

      the United  States or there  shall have been a  declaration  of a national
      emergency  or war by the United  States or (iv) there  shall have
      occurred such a material adverse change in general economic, political or
      financial conditions  (or the effect of  international  conditions  on the
      financial markets in the United States shall be such) as to make it, in
      the judgment of the  Underwriter,  impracticable  or  inadvisable  to
      proceed with the public  offering  or  delivery of the Stock on the terms
      and in the manner contemplated in the Final Prospectus.

            All opinions,  letters, evidence and certificates mentioned above or
elsewhere  in this  Agreement  shall  be  deemed  to be in  compliance  with the
provisions hereof only if they are in form and substance reasonably satisfactory
to counsel for the Underwriter.

            8.    INDEMNIFICATION AND CONTRIBUTION.

<PAGE>
                                                                          16



    (a)  The Company  shall  indemnify  and hold  harmless the  Underwriter, its
officers and  employees  and each person,  if any, who controls the  Underwriter
within the meaning of the  Securities  Act,  from and  against any loss,  claim,
damage  or  liability,  joint or  several,  or any  action  in  respect  thereof
(including,  but not limited to, any loss,  claim,  damage,  liability or action
relating  to  purchases  and  sales of the  Stock),  to which  the  Underwriter,
officer, employee or controlling person may become subject, under the Securities
Act or  otherwise,  insofar as such loss,  claim,  damage,  liability  or action
arises out of, or is based  upon,  (i) any untrue  statement  or alleged  untrue
statement of a material fact contained (A) in the  Registration  Statement,  the
Preliminary  Prospectus  or  the  Final  Prospectus,  or  in  any  amendment  or
supplement  thereto,  or (B) in any  blue  sky  application  or  other  document
prepared or  executed  by the  Company  (or based upon any  written  information
furnished by the Company)  specifically for the purpose of qualifying any or all
of the Stock under the securities laws of any state or other  jurisdiction  (any
such application,  document or information being hereinafter  called a "Blue Sky
Application") Blue Sky Application,  or (ii) the omission or alleged omission to
state in the  Registration  Statement,  the Preliminary  Prospectus or the Final
Prospectus,  or in any  amendment  or  supplement  thereto,  or in any  Blue Sky
Application any material fact required to be stated therein or necessary to make
the statements  therein not misleading,  and shall reimburse the Underwriter and
each such officer,  employee or controlling  person promptly upon demand for any
legal  or  other  expenses  reasonably  incurred  by the  Underwriter,  officer,
employee or controlling  person in connection with investigating or defending or
preparing to defend against any such loss, claim, damage, liability or action as
such expenses are  incurred;  PROVIDED,  HOWEVER,  that the Company shall not be
liable  under this  Section  8(a) in any such case to the  extent  that any such
loss,  claim,  damage,  liability or action arises out of, or is based upon, any
untrue  statement or alleged  untrue  statement or omission or alleged  omission
made in the  Registration  Statement,  the  Preliminary  Prospectus or the Final
Prospectus,  or in  any  such  amendment  or  supplement,  or in  any  Blue  Sky
Application  in  reliance  upon  and  in  conformity  with  written  information
concerning  the  Underwriter  furnished  to the  Company  by or on behalf of the
Underwriter  specifically for inclusion therein; and PROVIDED FURTHER that as to
the  Preliminary  Prospectus  this  indemnity  agreement  shall not inure to the
benefit of the Underwriter,  its officers or employees or any person controlling
the  Underwriter  on account of any loss,  claim,  damage,  liability  or action
arising  from the sale of the  Stock to any  person  by the  Underwriter  if the
Underwriter failed to send or give a copy of the Final Prospectus to that person
within the time  required by the  Securities  Act,  and the untrue  statement or
alleged untrue statement of any material fact or omission or alleged omission to
state a material fact in the  Preliminary  Prospectus was corrected in the Final
Prospectus, unless such failure resulted from non-compliance by the Company with
Section 5(c). The foregoing  indemnity agreement is in addition to any liability
which the Company  may  otherwise  have to the  Underwriter  or to any  officer,
employee or controlling person of the Underwriter.

    (b)  The  Underwriter  shall  indemnify  and hold  harmless the Company, its
officers and  employees,  each of its  directors  and each  person,  if any, who
controls the Company within the meaning of the Securities  Act, from and against
any loss, claim, damage or liability, joint or several, or any action in respect
thereof,  to which the  Company or any such  director,  officer  or  controlling
person may become  subject,  under the Securities  Act or otherwise,  insofar as
such loss, claim,  damage,  liability or action arises out of, or is based upon,
(i) any  untrue

<PAGE>
                                                                           17


statement or alleged  untrue  statement of a material fact  contained (A) in the
Registration Statement,  the Preliminary Prospectus or the Final Prospectus,  or
in any amendment or supplement  thereto,  or (B) in any Blue Sky  Application or
(ii) the omission or alleged  omission to state in the  Registration  Statement,
the  Preliminary  Prospectus  or the Final  Prospectus,  or in any  amendment or
supplement thereto, or in any Blue Sky Application any material fact required to
be stated  therein or necessary to make the statements  therein not  misleading,
but in each case only to the extent that the untrue  statement or alleged untrue
statement  or omission  or alleged  omission  was made in  reliance  upon and in
conformity with written information  concerning the Underwriter furnished to the
Company by or on behalf of the Underwriter  specifically for inclusion  therein,
and shall  reimburse the Company and any such  director,  officer or controlling
person for any legal or other expenses reasonably incurred by the Company or any
such director, officer or controlling person in connection with investigating or
defending or preparing to defend against any such loss, claim, damage, liability
or action as such expenses are incurred. The foregoing indemnity agreement is in
addition  to any  liability  which the  Underwriter  may  otherwise  have to the
Company or any such director, officer, employee or controlling person.

    (c)  Promptly after receipt by an indemnified  party under this Section 8 of
notice of any claim or the  commencement of any action,  the  indemnified  party
shall,  if a claim in respect  thereof is to be made  against  the  indemnifying
party  under this  Section 8,  notify the  indemnifying  party in writing of the
claim or the commencement of that action; PROVIDED, HOWEVER, that the failure to
notify the  indemnifying  party shall not relieve it from any liability which it
may have  under  this  Section  8 except to the  extent  it has been  materially
prejudiced by such failure. If any such claim or action shall be brought against
an indemnified  party, and it shall notify the indemnifying  party thereof,  the
indemnifying  party shall be entitled to participate  therein and, to the extent
that it wishes, jointly with any other similarly notified indemnifying party, to
assume  the  defense  thereof  with  counsel  reasonably   satisfactory  to  the
indemnified  party.  After notice from the indemnifying party to the indemnified
party of its  election  to assume  the  defense  of such  claim or  action,  the
indemnifying  party  shall not be liable to the  indemnified  party  under  this
Section  8 for  any  legal  or  other  expenses  subsequently  incurred  by  the
indemnified  party in connection  with the defense thereof other than reasonable
costs of investigation;  PROVIDED,  HOWEVER, that the Underwriter shall have the
right to employ counsel to represent  jointly the  Underwriter and its officers,
employees and controlling persons who may be subject to liability arising out of
any claim in respect of which indemnity may be sought by the Underwriter against
the  Company  under  this  Section  8 if,  in  the  reasonable  judgment  of the
Underwriter, it is advisable for the Underwriter and its officers, employees and
controlling persons to be jointly  represented by separate counsel,  and in that
event  the fees  and  expenses  of such  separate  counsel  shall be paid by the
Company.  No  indemnifying  party shall (i) without the prior written consent of
the  indemnified  parties  (which consent shall not be  unreasonably  withheld),
settle or compromise or consent to the entry of any judgment with respect to any
pending or  threatened  claim,  action,  suit or  proceeding in respect of which
indemnification  or  contribution  may be sought  hereunder  (whether or not the
indemnified  parties  are actual or  potential  parties to such claim or action)
unless such settlement,  compromise or consent includes an unconditional release
of each indemnified party from all liability arising out of such claim,  action,
suit or  proceeding,  or (ii) be liable for any  settlement  of any such  action
effected  without its written  consent (which consent shall not be  unreasonably
withheld),  but if settled with the

<PAGE>
                                                                         18


written consent of the indemnifying party or if there be a final judgment of the
plaintiff in any such action,  the  indemnifying  party agrees to indemnify  and
hold  harmless any  indemnified  party from and against any loss or liability by
reason of such settlement or judgment.

    (d)  If the  indemnification  provided for in this  Section  8 shall for any
reason be unavailable to or insufficient  to hold harmless an indemnified  party
under Section 8(a) or 8(b) in respect of any loss,  claim,  damage or liability,
or any action in respect thereof,  referred to therein,  then each  indemnifying
party shall, in lieu of indemnifying  such indemnified  party under Section 8(a)
or 8(b),  as the case may be, in respect of any loss,  claim damage or liability
or any action in respect thereof, referred to therein,  contribute to the amount
paid or  payable  by such  indemnified  party as a result of such  loss,  claim,
damage or liability, or action in respect thereof referred to in Section 8(a) or
8(b),  as the case may be, (i) in such  proportion  as shall be  appropriate  to
reflect the  relative  benefits  received by the Company on the one hand and the
Underwriter  on the  other  from  the  offering  of the  Stock  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 on
the one hand and the  Underwriter on the other with respect to the statements or
omissions which resulted in such loss, claim, damage or liability,  or action in
respect thereof,  as well as any other relevant  equitable  considerations.  The
relative benefits received by the Company on the one hand and the Underwriter on
the  other  with  respect  to such  offering  shall be  deemed to be in the same
proportion  as the total net proceeds  from the offering of the Stock  purchased
under this Agreement (before deducting  expenses) received by the Company on the
one hand, and the total underwriting  discounts and commissions  received by the
Underwriter  with  respect  to the  shares of the  Stock  purchased  under  this
Agreement, on the other hand, bear to the total gross proceeds from the offering
of the shares of the Stock  under this  Agreement,  in each case as set forth on
the cover of the Final  Prospectus.  The relative  fault shall be  determined by
reference to whether the untrue or alleged  untrue  statement of a material fact
or omission or alleged  omission to state a material fact relates to information
supplied by the Company or the Underwriter,  the intent of the parties and their
relative knowledge,  access to information and opportunity to correct or prevent
such statement or omission.  The Company and the Underwriter agree that it would
not be just and equitable if contributions pursuant to this Section 8(d) were to
be determined by pro rata allocation or by any other method of allocation  which
does not take into  account  the  equitable  considerations  referred to in this
Section 8(d). The amount paid or payable by an indemnified  party as a result of
the loss, claim, damage or liability, or action in respect thereof,  referred to
above in this  Section  8(d) shall be deemed to  include,  for  purposes of this
Section  8(d),  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 Section 8(d), the Underwriter
shall not be required to contribute  any amount in excess of the amount by which
the total price at which the Stock  underwritten  by it and  distributed  to the
public was offered to the public  exceeds  the amount of any  damages  which the
Underwriter  has otherwise  paid or become liable to pay by reason of any 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
Securities  Act) shall be entitled to  contribution  from any person who was not
guilty of such fraudulent misrepresentation.

     (e)  The  Underwriter  confirms  and  the  Company  acknowledges  that  the
statements  with  respect to the public  offering of the Stock set forth on the
cover page of, and under the caption  "Underwriting"  in, the Final  Prospectus
are correct and  constitute  the only  information  concerning  the  Underwriter
furnished  in  writing  to  the  Company   specifically  for  inclusion  in  the
Registration Statement and the Final Prospectus.

     9.  TERMINATION.  The  obligations  of  the  Underwriter  hereunder  may be
terminated  by the  Underwriter  by notice  given to and received by the Company
prior to delivery of and  payment for the Stock if,  prior to that time,  any of
the events  described in Sections  7(k),  7(l) or 7(m) shall have occurred or if
the  Underwriter  shall  decline to purchase the Stock for any reason  permitted
under this Agreement.

hereunder shall be in writing, and:

         (a)  if to the Underwriter, shall be delivered or sent by mail, telex

contained  in this  Agreement  shall also be deemed to be for the benefit of the
person or persons,  if any,  who control the  Underwriter  within the meaning of
Section  15 of the  Securities  Act  and  (B)  the  indemnity  agreement  of the
Underwriter  contained in Section 8(b) of this  Agreement  shall be deemed to be
for the benefit of directors of the Company and officers of the Company who have

the meaning of Section 15 of the  Securities  Act.  Nothing in this Agreement is
intended  or shall be  construed  to give any  person,  other  than the  persons

under or in respect of this Agreement or any provision contained herein.

          12. SURVIVAL. The respective indemnities, representations,  warranties
     and  agreements  of the  Company  and  the  Underwriter  contained  in this

behalf of them,  respectively,  pursuant to this  Agreement,  shall  survive the
delivery of and payment for the Stock and shall remain in full force and effect,
regardless  of any  investigation  made  by or on  behalf  of any of them or any
person controlling any of them.

and Regulations.

IN ACCORDANCE WITH THE LAWS OF NEW YORK.

            15.  COUNTERPARTS.  This  Agreement  may be  executed in one or more

reference  only and are not  intended to be part of, or to affect the meaning or
interpretation of, this Agreement.

            17. CONSENT TO JURISDICTION.  Each party irrevocably agrees that any

                               FORM OF OPINION OF
                        WACHTELL, LIPTON, ROSEN & KATZ
                    TO BE DELIVERED PURSUANT TO SECTION 7(b)

     (i)  The Company  has been duly incorporated  and is validly  existing as a
corporation in good standing under the laws of the State of Delaware.

     (ii)  The  Company  has  corporate  power and  authority  to own, lease and
operate its  properties  and to conduct its  business as  described in the Final
Prospectus, and to enter into and perform its obligations under the Underwriting
Agreement. The activities of each of the Company's subsidiaries are permitted to
subsidiaries of a savings and loan holding company.

     (iii) The Bank is the only "significant subsidiary" of the Company (as such
term is defined in Rule 1-02 of Regulation  S-X). The only  subsidiaries  of the
Company other than the Bank are the wholly-owned subsidiaries of the Bank listed
on Schedule 1 to the Underwriting  Agreement which,  considered in the aggregate
as a single subsidiary,  do not constitute a "significant subsidiary" as defined
in Rule 1-02 of Regulation S-X.

     (iv)  The  Company  has an  authorized  capitalization  as set forth in the
Final  Prospectus.  The shares of issued and  outstanding  capital  stock of the
Company,  including the shares of Stock to be purchased by the Underwriter  from
the Company, have been duly authorized and validly issued and are fully paid and
non-assessable;  and none of the  outstanding  shares  of  capital  stock of the
Company,  including the shares of Stock to be purchased by the Underwriter  from
the Company,  was issued in violation of any  preemptive or other similar rights
of any securityholder of the Company.

      (v) The Stock has been duly authorized by the Company and, when issued and
delivered against payment therefor as provided herein,  will be duly and validly
issued, fully paid and non-assessable and not subject to the preemptive or other
similar rights of any person; and the Stock conforms to all statements  relating
thereto  contained in the Final Prospectus and such description  conforms to the
rights set forth in the instruments defining the same.

     (vi)  The  Registration  Statement  has been declared  effective  under the
Securities Act; the Final  Prospectus was filed with the Commission  pursuant to
Rule  424(b) in the manner and within the time period  required by Rule  424(b);
and, to the best of our knowledge, no stop order suspending the effectiveness of
the  Registration  Statement  has been issued  under the  Securities  Act and no
proceedings  for that purpose have been  instituted or are pending or threatened
by the Commission.

     (vii)  The Registration Statement, the Final Prospectus, and each amendment
or supplement to the  Registration  Statement  and the Final  Prospectus,  as of
their respective  effective or issue dates (other than the financial  statements
and supporting  schedules included

<PAGE>
                                                                               2




therein or omitted therefrom,  as to which we express no opinion) complied as to
form in all material  respects with the  requirements  of the Securities Act and
the Rules and Regulations.

     (viii)  The  information  in  the  Final   Prospectus  under  the  captions
"Description of the Preferred Stock," "Description of Offered Securities" and in
the  Registration   Statement  under  "Part  II.  Information  Not  Required  in
Prospectus--Item  14.  Indemnification of Directors and Officers," to the extent
that such  information  constitutes  summaries  of  certain  terms of  documents
referred  to  therein,  constitute  accurate  summaries  of the  terms  of  such
documents in all material respects.

     (ix)  The  information in the Final  Prospectus  under the caption  "United
States Federal  Income Tax  Consequences,"  to the extent that such  information
purports to constitute  summaries of matters of United  States  federal tax laws
and regulations or legal conclusions with respect thereto,  constitute  accurate
summaries of the matters described therein in all material respects.

     (x)  To the best of our  knowledge,  there are no statutes  or  regulations
that are required to be described in the Final Prospectus that are not described
as required.

     (xi)   Neither  the  Company,   the  Bank  nor  any  of  their   respective
subsidiaries  is in  violation of its charter or by-laws and, to the best of our
knowledge,  no  default  by the  Company,  the Bank or any of  their  respective
subsidiaries  exists  in the  due  performance  or  observance  of any  material
obligation,   agreement,  covenant  or  condition  contained  in  any  contract,
indenture,   mortgage,  loan  agreement,  note,  lease  or  other  agreement  or
instrument that is described or referred to in the Registration Statement or the
Final Prospectus or filed as an exhibit to the Registration Statement.

     (xii)  No filing with, or authorization, approval, consent, license, order,
registration, qualification or decree of, any court or governmental authority or
agency,  domestic or foreign  including,  without  limitation,  the OTS and FDIC
(other than under the Securities Act and the Rules and  Regulations,  which have
been  obtained,  or as may be required  under the securities or blue sky laws of
the various states,  as to which we express no opinion) is necessary or required
for the  performance by the Company of its  obligations  under the  Underwriting
Agreement  in  connection  with the offering or sale of the Stock by the Company
under the  Underwriting  Agreement,  for the  consummation by the Company of the
transactions contemplated by the Underwriting Agreement.

      (xiii)  The  execution,  delivery  and  performance  of  the  Underwriting
Agreement by the Company,  the  consummation  of the  transactions  contemplated
thereby,   and  compliance  by  the  Company  with  its  obligations  under  the
Underwriting  Agreement  have been duly  authorized by all  necessary  corporate
action and do not and will not result in any violation of the  provisions of the
charter or by-laws of the Company or any of its subsidiaries,  or any applicable
law, statute, rule, regulation, judgment, order, writ or decree, known to us, of
any  government,  governmental  instrumentality  or court,  domestic or foreign,
having jurisdiction over the Company.  The Underwriting  Agreement has been duly
authorized, executed and delivered by the Company.

      (xiv) To the best of our knowledge, there are no persons with registration
rights or other similar rights to have any securities registered pursuant to the
Registration  Statement  or  otherwise  registered  by  the  Company  under  the
Securities Act, except as described in

<PAGE>
                                                                               3


Registration  Statement or as set forth in any  agreement  described  therein as
containing such rights.

     (xv)  The Company is not, and upon the sale of the Stock as contemplated in
the Underwriting  Agreement and the application of the net proceeds therefrom as
described in the Final  Prospectus  will not be, an  "investment  company" or an
entity "controlled" by an "investment company," as such terms are defined in the
1940 Act.

      Nothing has come to our  attention  that would lead us to believe that the
Registration Statement or any amendment thereto (except for financial statements
and schedules and other financial data included therein or omitted therefrom, as
to which we make no statement),  at the time such Registration  Statement or any
such amendment  became  effective,  contained an untrue  statement of a material
fact or  omitted  to state a  material  fact  required  to be stated  therein or
necessary  to make the  statements  therein  not  misleading  or that the  Final
Prospectus  or  any  amendment  or  supplement  thereto  (except  for  financial
statements and schedules and other  financial  data included  therein or omitted
therefrom,  as to which we make no statement),  at the time the Final Prospectus
was issued,  at the time any such amended or supplemented  Final  Prospectus was
issued or at the Closing  Date,  included or includes an untrue  statement  of a
material fact or omitted or omits to state a material fact necessary in order to
make the statements  therein, in the light of the circumstances under which they
were made, not misleading.

      In  rendering  such  opinion,  such counsel may rely as to matters of fact
(but  not  as to  legal  conclusions),  to  the  extent  they  deem  proper,  on
certificates of responsible  officers of the Company and public officials.  Such
opinion shall not state that it is to be governed or qualified by, or that it is
otherwise subject to, any treatise, written policy or other document relating to
legal opinions,  including,  without limitation, the Legal Opinion Accord of the
ABA  Section of  Business  Law  (1991).  All terms used but not  defined in this
exhibit should have the meanings ascribed to them in the Underwriting  Agreement
and should be defined accordingly in the form of opinion to be delivered.

                               FORM OF OPINION OF
                               JONATHON K. HEFFRON
                         GENERAL COUNSEL OF THE COMPANY,
                    TO BE DELIVERED PURSUANT TO SECTION 7(c)

      (i) The Company has been duly  incorporated  and is validly  existing as a
corporation in good standing under the laws of the State of Delaware.

      (ii) The Company  has  corporate  power and  authority  to own,  lease and
operate its  properties  and to conduct its  business as  described in the Final
Prospectus, and to enter into and perform its obligations under the Underwriting
Agreement. The activities of each of the Company's subsidiaries are permitted to
subsidiaries of a savings and loan company.

      (iii) The Bank is the only  "significant  subsidiary"  of the  Company (as
such term is defined in Rule 1-02 of Regulation  S-X). The only  subsidiaries of
the Company other than the Bank are the  wholly-owned  subsidiaries  of the Bank
listed on Schedule 1 to the  Underwriting  Agreement,  which,  considered in the
aggregate as a single subsidiary,  do not constitute a "significant  subsidiary"
as defined in Rule 1-02 of Regulation  S-X. The  activities of all of the Bank's
subsidiaries  are permitted to  subsidiaries  of a federally  chartered  savings
bank, the deposits of which are insured by the SAIF,  which is  administered  by
the FDIC.

      (iv)  The  Bank  is  a  federally   chartered  stock  savings  bank,  duly
incorporated and validly  existing under the laws of the United States,  and the
Bank's charter is in full force and effect.  The Bank is a member of the Federal
Home Loan Bank of Dallas and has been duly issued a certificate stating that its
savings  accounts are insured by the FDIC in accordance with applicable law, and
no proceedings for the termination or revocation of such membership or insurance
are pending or, to the best of my knowledge, threatened.

      (v) The Bank has corporate  power and authority to own,  lease and operate
its properties and to conduct its business as described in the Final Prospectus.

      (vi) Each  subsidiary  of the Bank has been duly  organized and is validly
existing as a corporation in good standing under the laws of the jurisdiction of
its  incorporation and has the power and authority to own, lease and operate its
properties and to conduct its business as described in the Final Prospectus. The
activities  described in the Final Prospectus of each of the Bank's subsidiaries
are permitted  activities of subsidiaries of a federally chartered savings bank,
the  deposits of which are  insured by the SAIF,  which is  administered  by the
FDIC.

      (vii) The Company, the Bank and each subsidiary of the Company or the Bank
is duly qualified as a foreign  corporation to transact  business and is in good
standing in each jurisdiction in which such  qualification is required,  whether
by reason of the  ownership  or leasing of property or the conduct of  business,
except  where the  failure  so to qualify  or to be in good  standing  would not
result in a Material Adverse Effect.

                                                                               2


      (viii)  All of the issued and  outstanding  capital  stock of the Bank and
each  subsidiary of the Bank has been duly  authorized  and validly  issued,  is
fully  paid  and  non-assessable  and,  except  as  otherwise  disclosed  in the
Registration   Statement,   is  owned  by  the  Company,   directly  or  through
subsidiaries,  to the  best of my  knowledge,  free and  clear  of any  security
interest,  mortgage,  pledge,  lien,  encumbrance,  claim or equity; none of the
outstanding shares of capital stock of any subsidiary was issued in violation of
the preemptive or similar rights of any securityholder of such subsidiary.

      (ix) The  Company  has an  authorized  capitalization  as set forth in the
Final  Prospectus;  the shares of issued and  outstanding  capital  stock of the
Company,  including the shares of Stock to be purchased by the Underwriter  from
the Company, have been duly authorized and validly issued and are fully paid and
non-assessable;  and none of the  outstanding  shares  of  capital  stock of the
Company,  including the shares of Stock to be purchased by the Underwriter  from
the Company,  was issued in violation of any  preemptive or other similar rights
of any securityholder of the Company.

      (x) The documents  incorporated  by reference in the Final  Prospectus and
any further  amendment or supplement to any such  incorporated  document made by
the Company prior to the Closing Date (other than the financial  statements  and
related schedules  contained  therein,  as to which such counsel need express no
opinion),  when they became effective or were filed with the Commission,  as the
case may be, complied as to form in all material  respects with the requirements
of the  Securities  Act or the Exchange  Act, as  applicable,  and the rules and
regulations of the Commission thereunder.

      (xi)  The sale of the  Stock  to the  Underwriter  by the  Company  is not
subject to the preemptive or other similar rights of any  securityholder  of the
Company.  The Stock conforms to all statements relating thereto contained in the
Final  Prospectus and such  description  conforms to the rights set forth in the
instruments defining the same.

      (xii)  There is not pending or, to my  knowledge,  threatened  any action,
suit, proceeding, inquiry or investigation,  to which the Company or the Bank or
any of their respective subsidiaries is a party, or to which the property of the
Company or the Bank or any of their respective  subsidiaries is subject,  before
or brought by any court or  governmental  agency or body,  domestic  or foreign,
which might  reasonably be expected to result in a Material  Adverse Effect,  or
which might  reasonably  be  expected to  materially  and  adversely  affect the
properties  or  assets  thereof  or  the   consummation   of  the   transactions
contemplated in the Underwriting  Agreement or the performance by the Company of
its obligations  thereunder.  The aggregate of all pending legal or governmental
proceedings  to  which  the  Company,  the  Bank,  or  any of  their  respective
subsidiaries  is known by me to be a party or of which  any of their  respective
property or assets is the subject  which are not  described in the  Registration
Statement,  including  ordinary routine  litigation  incidental to the business,
could not reasonably be expected to result in a Material Adverse Effect.  To the
best of my knowledge, neither the Company nor any of its subsidiaries is a party
to any written  agreement or  memorandum  of  understanding  with, or commitment
letter or similar  undertaking  to, or subject to any order or directive  issued
by, or a recipient of any

<PAGE>
                                                                               3


extraordinary  supervisory  letter from, or has adopted any board resolutions at
the  request  of,  any  federal or state  government  agency or  authority  with
responsibility  for the supervision or regulation of depository  institutions or
their  holding  companies or the  insurance of deposits,  which in any such case
materially restricts the conduct of its business or in any manner relates to its
capital adequacy, its credit policies or its management,  nor has the Company or
any of its subsidiaries been advised by any such regulatory authority that it is
contemplating  issuing or requesting any such order, decree,  written agreement,
memorandum of understanding, extraordinary supervisory letter, commitment letter
or  similar  undertakings  or  board  resolutions.  No  labor  dispute  with the
employees of the Company or any  subsidiary  exists or, to the  knowledge of the
Company,  is imminent,  and the Company is not aware of any existing or imminent
labor  disturbance by the employees of any of its or any subsidiary's  principal
suppliers,  manufacturers,  customers or contractors, which, in either case, may
reasonably be expected to result in a Material Adverse Effect.

      (xiii) To the best of my knowledge,  there are no statutes or  regulations
that are required to be described in the Final Prospectus that are not described
as required.

      (xiv) All  descriptions  in the  Registration  Statement of contracts  and
other  documents  to which  the  Company  or its  subsidiaries  are a party  are
accurate in all material  respects;  to the best of my  knowledge,  there are no
franchises,  contracts, indentures, mortgages, loan agreements, notes, leases or
other  instruments  required to be described or referred to in the  Registration
Statement  or to be filed as  exhibits  thereto  other than those  described  or
referred to therein or filed or incorporated  by reference as exhibits  thereto,
and the descriptions  thereof or references  thereto are correct in all material
respects.

      (xv)  Neither  the  Company,   the  Bank  nor  any  of  their   respective
subsidiaries  is in  violation  of its  charter or by-laws and no default by the
Company,  the Bank or any of their  respective  subsidiaries  exists  in the due
performance  or observance of any material  obligation,  agreement,  covenant or
condition contained in any contract, indenture,  mortgage, loan agreement, note,
lease or other  agreement or instrument  that is described or referred to in the
Registration  Statement  or the Final  Prospectus  or filed as an exhibit to the
Registration Statement.

      (xvi)  The  execution,   delivery  and  performance  of  the  Underwriting
Agreement by the Company, and the consummation of the transactions  contemplated
thereby  and  compliance  by  the  Company  with  its   obligations   under  the
Underwriting  Agreement  has been duly  authorized  by all  necessary  corporate
action and do not and will not,  whether with or without the giving of notice or
lapse of time or both,  conflict  with or  constitute a breach of, or default or
Repayment Event (as defined in Section l(k) of the Underwriting Agreement) under
or result in the creation or imposition of any lien,  charge or encumbrance upon
any  property  or  assets  of the  Company  or any  subsidiary  pursuant  to any
contract,  indenture,  mortgage, deed of trust, loan or credit agreement,  note,
lease or any other agreement or instrument, known to me, to which the Company or
any  subsidiary  is a party or by which  it or any of them may be  bound,  or to
which any of the  property  or assets of the  Company,  the Bank or any of their
respective  subsidiaries  is subject  (except  for such  conflicts,  breaches or
defaults or liens,  charges or encumbrances  that

<PAGE>
                                                                               4


would not result in a Material Adverse  Effect),  nor will such action result in
any violation of the  provisions  of the charter or by-laws of the Company,  the
Bank or any of their respective  subsidiaries,  or any applicable law,  statute,
rule,  regulation,  judgment,  order,  writ  or  decree,  known  to  me,  of any
government,  governmental  instrumentality or court, domestic or foreign, having
jurisdiction over the Company, the Bank, or any of their respective subsidiaries
or any of their respective properties, assets or operations.

      (xvii)  There are no persons  with  registration  rights or other  similar
rights to have any securities registered pursuant to the Registration  Statement
or otherwise  registered  by the Company or the Bank under the  Securities  Act,
except as described in  Registration  Statement or as set forth in any agreement
described therein as containing such rights.

      (xviii) The Company,  the Bank and each of its  subsidiaries  possess such
Governmental Licenses issued by the appropriate federal, state, local or foreign
regulatory  agencies or bodies necessary to conduct the business now operated by
them; the Company,  the Bank and each of its subsidiaries are in compliance with
the terms and  conditions of all such  Governmental  Licenses,  except where the
failure so to comply  would  not,  singly or in the  aggregate,  have a Material
Adverse Effect; all of the Governmental Licenses are valid and in full force and
effect,  except when the invalidity of such Governmental Licenses or the failure
of such  Governmental  Licenses to be in full force and effect  would not have a
Material  Adverse  Effect;  and neither the  Company,  the Bank nor any of their
respective  subsidiaries has received any notice of proceedings  relating to the
revocation or modification of any such Governmental Licenses which, singly or in
the  aggregate,  if the subject of an unfavorable  decision,  ruling or finding,
would result in a Material Adverse Effect.

      (xix) The Company, the Bank and each of their respective subsidiaries have
good  and  marketable  title  to all  real,  tangible  and  intangible  property
reflected in the most recent balance sheet  included in the Final  Prospectus as
owned by the Company,  the Bank and its subsidiaries and good title to all other
properties  reflected  in the most recent  balance  sheet  included in the Final
Prospectus  as owned by them,  in each  case,  free and clear of all  mortgages,
pledges, liens, security interests,  claims, restrictions or encumbrances of any
kind except such as (A) are  described  in the Final  Prospectus  or (a) do not,
singly or in the aggregate,  materially affect the value of such property and do
not interfere  with the use made and proposed to be made of such property by the
Company, the Bank or any of their respective  subsidiaries;  or, with respect to
any such real property,  render title unmarketable as to a material part thereof
and all of the leases and subleases material to the business of the Company, the
Bank and of their  respective  subsidiaries,  considered as one enterprise,  and
under which the Company, the Bank or any of their respective  subsidiaries holds
properties described in the Final Prospectus,  are in full force and effect, and
neither the Company,  the Bank nor any of their respective  subsidiaries has any
notice  of any  material  claim of any sort  that has been  asserted  by  anyone
adverse  to the  rights  of the  Company,  the bank any of  their  respective
subsidiaries under any of the leases or subleases  mentioned above, or affecting
or  questioning  the rights of the Company,  the Bank or such  subsidiary to the
continued possession of the leased or subleased premises under any such lease or
sublease.

                                                                               5

      (xx) Except as described in the Registration  Statement or except as would
not, singly or in the aggregate,  result in a Material  Adverse Effect,  (A) the
Company, the Bank and each of their respective  subsidiaries is not in violation
of any  Environmental  Laws,  (B) the  Company,  the  Bank  and  each  of  their
respective subsidiaries have all permits,  authorizations and approvals required
under any applicable  Environmental  Laws and are each in compliance  with their
requirements,  (C) there are no pending  or, to the  knowledge  of the  Company,
threatened  administrative,  regulatory  or judicial  actions,  suits,  demands,
demand  letters,   claims,   liens,   notices  of  noncompliance  or  violation,
investigation  or  proceedings  relating  to any  Environmental  Law against the
Company,  the  Bank  or any of  their  respective  subsidiaries  and  (D) to the
knowledge  of the  Company  there  are no  events or  circumstances  that  might
reasonably  be  expected  to  form  the  basis  of  an  order  for  clean-up  or
remediation,  or  an  action,  suit  or  proceeding  by  any  private  party  or
governmental body or agency,  against or affecting the Company,  the sank or any
of  their  respective  subsidiaries  relating  to  Hazardous  Materials  or  any
Environmental Laws.

      (xxi) In the event the Company shall become either  directly or indirectly
a bank  holding  company  for  purposes  of the BHC Act and the BHC  Rules,  the
current  activities of the Company and its  subsidiaries  (as defined in the BHC
Rules) would be activities  permissible for a bank holding company under the BHC
Act and the BHC Rules.

      (xxii) No filing  with,  or  authorization,  approval,  consent,  license,
order,  registration,  qualification  or decree  of,  any court or  governmental
authority or agency, domestic or foreign including,  without limitation, the OTS
and FDIC is necessary or required by federal  banking laws and  regulations  for
the  performance  by the  Company  of its  obligations  under  the  Underwriting
Agreement  in  connection  with the offering or sale of the Stock by the Company
under the  Underwriting  Agreement  or the  consummation  by the  Company of the
transactions contemplated by the Underwriting Agreement.

      Nothing has come to my  attention  that would lead me to believe  that the
Registration  Statement or any  amendment  thereto,  including  the  information
included in any prospectus that was omitted from such Registration  Statement at
the time it became effective but that is deemed to be part of such  Registration
Statement at the time it became effective  (except for financial  statements and
schedules and other financial data included therein or omitted therefrom,  as to
which I make no statement),  at the time such Registration Statement or any such
amendment became effective,  contained an untrue statement of a material fact or
omitted to state a material fact  required to be stated  therein or necessary to
make the statements  therein not misleading or that the Final  Prospectus or any
amendment or supplement  thereto (except for financial  statements and schedules
and other financial data included  therein or omitted  therefrom,  as to which I
make no statement), at the time the Final Prospectus was issued, at the time any
such amended or supplemented  Final  Prospectus was issued or at either Delivery
Date,  included or includes an untrue statement of a material fact or omitted or
omits to  state a  material  fact  necessary  in  order  to make the  statements
therein,  in the light of the  circumstances  under  which they were  made,  not
misleading.

      In  rendering  such  opinion,  such counsel may rely as to matters of fact
(but  not  as to  legal  conclusions),  to  the  extent  they  deem  proper,  on
certificates of responsible  officers of the Company and public officials.  Such
opinion shall not state that it is to be governed or qualified by, or that it is
otherwise subject to, any treatise, written policy or other document relating to

                                BANK UNITED CORP.

                      ------------------------------------

                         Pursuant to Section 151 of the
                General Corporation Law of the State of Delaware
                      ------------------------------------

          BANK UNITED CORP., a corporation organized and existing under the laws
of the State of Delaware (the "Corporation"), HEREBY CERTIFIES that the
following resolutions were duly adopted by the Board of Directors of the
Corporation on August 5, 1999, pursuant to authority conferred upon the Board of
Directors by the provisions of the Restated Certificate of Incorporation of the
Corporation which authorize the issuance of up to 10,000,000 shares of preferred
stock of $0.01 par value per share (the "Preferred Stock"):

                  RESOLVED that, pursuant to resolutions of the Board of
Directors of Bank United Corp. (the "Corporation") adopted on August 5, 1999,
the issue of 1,200,000 shares of Series A Preferred Stock, $50 liquidation
preference per share ($0.01 par value), is hereby authorized and the
designation, preferences and privileges, voting rights, relative, participating,
optional and other special rights, and qualifications, limitations and
restrictions of all 1,200,000 shares of this Series, in addition to those set
forth in the Restated Certificate of Incorporation of the Corporation, are
hereby fixed as follows:

         1. Designation. The designation of this Series shall be Series A
Preferred Stock (hereinafter referred to as this "Series"), and the number of
shares constituting this Series shall be 1,200,000. Shares of this Series shall
have a liquidation preference of $50. The number of authorized shares of this
Series may be reduced (but not below the number then issued and outstanding) by
further resolution duly adopted by the Board of Directors of the Corporation or
by any duly authorized committee of the Board of Directors (collectively, the
"Board of Directors") and by the filing of a certificate pursuant to the
provisions of the General Corporation Law of the State of Delaware stating that
such reduction has been so authorized, but the number of authorized shares of
this Series shall not be increased.

         2. Dividends. (a) The holders of shares of this Series shall be
entitled to receive cash dividends, when, as and if declared by the Board of
Directors, out of funds legally available for
<PAGE>
                                                                          2

that purpose, at the rates set forth below in this Section 2. Dividends on the
shares of this Series shall be payable, when, as and if declared by the Board of
Directors, quarterly in arrears on February 15, May 15, August 15 and November
15 of each year (each, a "Dividend Payment Date"), commencing on November 15,
1999, or if such date is not a Business Day (as defined below), the next
succeeding Business Day. Each such dividend shall be paid to the holders of
record of shares of this Series as they appear on the stock register of the
Corporation on the applicable Record Date, as shall be fixed by the Board of
Directors; provided, however, that holders of shares of this Series called for
redemption on a Redemption Date falling between the record date associated with
a Dividend Payment Date and such Dividend Payment Date shall receive the
applicable dividend payment, together with all other accumulated and unpaid
dividends on such date as shall be fixed for redemption. Dividends on the shares
of this Series shall accumulate and be cumulative from the date of original
issuance. "Business Day" shall mean any day other than a Saturday or Sunday or a
day on which banking institutions in New York City are authorized or required by
law or executive order to remain closed.

         (b) Dividends payable on the shares of this Series for the period from
August 10, 1999 through and including November 14, 1999 (the "Initial Dividend
Period") shall be $1.017 per share. For each quarterly dividend period after the
Initial Dividend Period (each such quarterly dividend period and the Initial
Dividend Period being hereinafter referred to individually as a "Dividend
Period") through and including the Dividend Period ending February 15, 2000,
dividends payable on the shares of this Series shall be payable at a rate per
annum of the liquidation preference thereof equal to 7.55%. For each Dividend
Period beginning on or after February 15, 2000, dividends payable on the shares
of this Series shall be payable at a rate per annum of the liquidation
preference thereof equal to 8.55%. The amount of dividends per share for each
Dividend Period shall be computed by dividing the applicable rate for such
Dividend Period by four and applying the resulting rate to the liquidation
preference per share of this Series. Each Dividend Period (other than the
Initial Dividend Period) shall commence on a Dividend Payment Date and shall end
on and include the day next preceding the next Dividend Payment Date.

         (c) Dividends payable on this Series for any period greater or less
than a full Dividend Period, other than the Initial Dividend Period, shall be
computed on the basis of a 360-day year consisting of twelve 30-day months and,
for any period less than one month, the actual number of days elapsed in the
period.

         (d) No full dividends shall be declared or paid or set apart for
payment on the Preferred Stock of any series ranking, as to dividends, on a
parity with or junior to this Series for any period unless full cumulative
dividends on the shares of this Series for all full Dividend Periods ending on
or prior to the date of such dividends on such other series of Preferred Stock
have been or contemporaneously are declared and paid or declared and a sum
sufficient for the payment thereof set apart for such payment. When dividends
are not paid in full, as aforesaid, upon the shares of this Series and any other
series of Preferred Stock ranking on a parity as to dividends with this Series,
all dividends declared upon shares of this Series and any other series of
Preferred Stock ranking on a parity as to dividends with this Series shall be
declared pro rata
<PAGE>
                                                                          3



so that the amount of dividends declared per share on this Series and such other
Preferred Stock shall in all cases bear to each other the same ratio that
accrued and unpaid dividends per share on the shares of this Series and such
other Preferred Stock bear to each other. No interest, or sum of money in lieu
of interest, shall be payable in respect of any dividend payment or payments on
this Series which may be in arrears.

         (e) So long as any shares of this Series are outstanding, no dividend
(other than a dividend in Common Stock or in any other stock ranking junior to
this Series as to dividends and upon liquidation and other than as provided in
paragraph (d) of this Section 2) shall be declared or paid or set aside for
payment or other distribution declared or made upon the Common Stock or upon any
other stock ranking junior to or on a parity with this Series as to dividends or
upon liquidation, nor shall any Common Stock or any other stock of the
Corporation ranking junior to or on a parity with this Series as to dividends or
upon liquidation be redeemed, purchased or otherwise acquired for any
consideration (or any moneys be paid to or made available for a sinking fund for
the redemption of any shares of any such stock) by the Corporation (except by
conversion into or exchange for stock of the Corporation ranking junior to this
Series as to dividends and upon liquidation), unless, in each case, full
cumulative dividends on all outstanding shares of this Series for all full
Dividend Periods ending on or prior to the date of such other dividend,
distribution, redemption, purchase or other acquisition, shall have been or
contemporaneously are paid or declared and a sum sufficient for the payment
thereof set aside for such payment.

         (f) If any dividends payable on this Series with respect to any fiscal
year of the Corporation are not eligible for the dividends-received deduction
set forth in Section 243(a)(1) of the Internal Revenue Code of 1986, as amended
(the "Code") (or any successor provision), solely because this Series is treated
as indebtedness pursuant to a final determination within the meaning of Section
1313(a) of the Code to which the Corporation or any U.S. corporate holder is a
party ("Applicable Distribution(s)"), the Corporation shall, within 45 days
after the receipt by the Corporation of such determination, provide notice
thereof to the transfer agent. The transfer agent shall mail a copy of such
notice to each Qualified Investor (as defined below) at the address specified in
the records of the transfer agent as promptly as practicable after its receipt
of such notice from the Corporation, together with instructions for furnishing
the certifications referred to below to the transfer agent. The Corporation
shall, within fifteen days after such notice is given to the transfer agent, pay
to the transfer agent an amount equal to the aggregate Additional Amounts (as
defined below) with respect to all Applicable Distributions during such fiscal
year. Upon receipt of such aggregate Additional Amounts and receipt of an
affidavit from each Qualified Investor, on a form provided by Bank United,
certifying that (i) the Qualified Investor is a domestic taxable corporation and
(ii) if the preferred stock had been treated as debt for U.S. income tax
purposes, the dividends-received deduction with respect to each Applicable
Distribution would have been allowed and available to the Qualified Investor, in
light of its particular facts and circumstances, under all relevant Sections of
the Internal Revenue Code, including, without limitation, Section 246(c),
Section 246A and Section 1059, the transfer agent shall distribute to each such
Qualified Investor the Additional Amount to which such Qualified Investor is
entitled with respect to each Applicable Distribution received by such Qualified
<PAGE>
                                                                          4

Investor during such fiscal year. Any portion of the aggregate Additional
Amounts not distributed by the transfer agent shall be returned to the
Corporation within 90 days of the transfer agent's receipt of those amounts.

                  "Qualified Investor" means a U.S. corporate holder of record
during any fiscal year which was entitled to receive an Applicable Distribution
during such fiscal year.

                  "Additional Amount(s)" means payment with respect to any
Applicable Distribution of an amount which, when taken together with such
Applicable Distribution, would cause the net yield in dollars (after federal
income tax consequences) from the aggregate of both the Applicable Distributions
and the Additional Amount, to be equal to the net yield in dollars (after
federal income tax consequences) that would have been realized if the amount of
the aggregate Applicable Distributions not treated as a dividend instead had
been treated as a dividend, giving effect to the dividends-received deduction,
for federal income tax purposes. Such Additional Amount shall be calculated with
consideration being given to the time value of money, applying the corporate
underpayment rate as defined in Section 6622(a)(2) of the Code as the interest
factor, assuming the Additional Amount is subject to tax as ordinary income, and
using the maximum marginal corporate federal tax rate applicable to ordinary
income.

                  The foregoing provisions shall apply to the Initial Dividend
Period and each subsequent Dividend Period.

         3. Redemption. (a) Optional Redemption. The shares of this Series are
not redeemable prior to February 15, 2000. The Corporation, at its option, may
redeem shares of this Series, as a whole or in part, at any time or from time to
time, on or after February 15, 2000 at a redemption price of $50 per share plus
accrued and unpaid cumulative dividends thereon (whether or not declared) to the
date fixed for redemption.

         (b) Mandatory Redemption. The Corporation shall redeem, from any source
of funds legally available therefor, all issued and outstanding shares of this
Series, in whole and not in part, on August 15, 2004, at a redemption price of
$50 per share plus accrued and unpaid cumulative dividends thereon (whether or
not declared) to the date fixed for redemption.

         (c)      Redemption Procedures.

                   (i) In the event that, pursuant to paragraph (a) above, fewer
         than all the outstanding shares of this Series are to be redeemed, the
         number of shares to be redeemed shall be determined by the Board of
         Directors and the shares to be redeemed shall be determined by lot or
         pro rata as may be determined by the Board of Directors or by any other
         method as may be determined by the Board of Directors in its sole
         discretion to be equitable, provided that such method satisfies any
         applicable requirements of any securities exchange on which this Series
         is listed.

                                                                          5

                  (ii) In the event the Corporation shall redeem shares of this
         Series, notice of such redemption shall be given by first class mail,
         postage prepaid, mailed not less than 30 or more than 60 days prior to
         the redemption date, to each holder of record of the shares to be
         redeemed, at such holder's address as the same appears on the stock
         register of the Corporation. Each such notice shall state: (i) the
         redemption date; (ii) the number of shares of this Series to be
         redeemed and, if fewer than all the shares held by such holder are to
         be redeemed, the number of such shares to be redeemed from such holder;
         (iii) the redemption price; (iv) the place or places where certificates
         for such shares are to be surrendered for payment of the redemption
         price; and (v) that dividends on the shares to be redeemed shall cease
         to accrue on the redemption date.

                  (iii) Notice having been mailed as aforesaid, from and after
         the redemption date (unless default shall be made by the Corporation in
         providing money for the payment of the redemption price) dividends on
         the shares of this Series so called for redemption shall cease to
         accrue, and said shares shall no longer be deemed to be outstanding,
         and all rights of the holders thereof as stockholders of the
         Corporation (except the right to receive from the Corporation the
         redemption price) shall cease. Upon surrender in accordance with said
         notice of the certificates for any shares so redeemed (properly
         endorsed or assigned for transfer, if the Board of Directors shall so
         require and the notice shall so state), such shares shall be redeemed
         by the Corporation at the redemption price aforesaid. In case fewer
         than all the shares represented by any such certificate are redeemed, a
         new certificate shall be issued representing the unredeemed shares
         without cost to the holder thereof.

                  (iv) Any shares of this Series which shall at any time have
         been redeemed shall, after such redemption, have the status of
         authorized but unissued shares of Preferred Stock, without designation
         as to series until such shares are once more designated as part of a
         particular series by the Board of Directors.

                  (v) Notwithstanding the foregoing provisions of this Section
         3, if full cumulative dividends on all outstanding shares of this
         Series are in arrears, no shares of this Series shall be redeemed
         unless all outstanding shares of this Series are simultaneously
         redeemed, and the Corporation shall not purchase or otherwise acquire
         any shares of this Series; provided, however, that the foregoing shall
         not prevent the purchase or acquisition of shares of this Series
         pursuant to a purchase or exchange offer made on the same terms to
         holders of all outstanding shares of this Series.

         4. Conversion. The holders of shares of this Series shall not have any
rights to convert such shares into shares of any other class or series of
capital stock of the Corporation.

         5. Liquidation Rights. (a) Upon the voluntary or involuntary
dissolution, liquidation or winding up of the Corporation, the holders of the
shares of this Series shall be entitled to receive and to be paid out of the
assets of the Corporation available for distribution to its stockholders, before
any payment or distribution shall be made on the Common Stock or on
<PAGE>
                                                                          6

any other class of stock ranking junior to this Series upon liquidation, the
amount of $50 per share, plus accrued and unpaid cumulative dividends (whether
or not declared) to the date of the liquidating distribution.

         (b) After the payment to the holders of the shares of this Series of
the full preferential amounts provided for in this Section 5, the holders of
this Series as such shall have no right or claim to any of the remaining assets
of the Corporation.

         (c) If, upon any voluntary or involuntary dissolution, liquidation, or
winding up of the Corporation, the amounts payable with respect to the shares of
this Series and any other shares of stock of the Corporation ranking as to any
such distribution on a parity with the shares of this Series are not paid in
full, the holders of the shares of this Series and of such other shares shall
share ratably in any such distribution of assets of the Corporation in
proportion to the full respective distributions to which they are entitled.

         (d) Neither the sale of all or substantially all the property or
business of the Corporation, nor the merger or consolidation of the Corporation
into or with any other corporation or the merger or consolidation of any other
corporation into or with the Corporation, shall be deemed to be a dissolution,
liquidation or winding up, voluntary or involuntary, for the purposes of this
Section 5.

         6. Ranking. For purposes of this resolution, any stock of any class or
classes of the Corporation shall be deemed to rank:

         (a) prior to the shares of this Series, either as to dividends or upon
liquidation, if the holders of such class or classes shall be entitled to the
receipt of dividends or of amounts distributable upon dissolution, liquidation
or winding up of the Corporation, as the case may be, in preference or priority
to the holders of shares of this Series;

         (b) on a parity with shares of this Series, either as to dividends or
upon liquidation, whether or not the dividend rates, dividend payment dates or
redemption or liquidation prices per share or sinking fund provisions, if any,
be different from those of this Series (and whether or not such dividends shall
accumulate), if the holders of such stock shall be entitled to the receipt of
dividends or of amounts distributable upon dissolution, liquidation or winding
up of the Corporation, as the case may be, without preference or priority, one
over the other, as between the holders of such stock and the holders of shares
of this Series; and

         (c) junior to shares of this Series, either as to dividends or upon
liquidation, if such class shall be Common Stock or if the holders of shares of
this Series shall be entitled to receipt of dividends or of amounts
distributable upon dissolution, liquidation or winding up of the Corporation, as
the case may be, in preference or priority to the holders of shares of such
class or classes.

         (d) The shares of Series B Preferred Stock of the Corporation shall
rank on a parity with the shares of this Series.
<PAGE>
                                                                          7

         7. Voting Rights. The holders of the shares of this Series shall have
the following voting rights:

         (a) Each share of this Series will have the right to vote, with each
share of this Series having 0.10 vote, in connection with matters submitted
generally to the holders of the common stock and other capital stock of the
Corporation entitled to vote in respect of matters submitted to the stockholders
of the Corporation generally. For these purposes, the holders of the shares of
this Series and the holders of the common stock and such other capital stock of
the Corporation, so entitled to vote, shall vote as a single class.

         (b) Unless the vote or consent of the holders of a greater number of
shares shall then be required by law, the approval of the holders of at least
two-thirds of the then-outstanding shares of this Series, given in person or by
proxy, either in writing or by a vote at a meeting called for the purpose at
which the holders of shares of this Series shall vote together as a separate
class, shall be required for authorizing, effecting or validating any amendment,
alteration or repeal, whether by merger, consolidation or otherwise, of any of
the provisions of the Restated Certificate of Incorporation of the Corporation
or of any certificate amendatory thereof or supplemental thereto (including any
Certificate of Designations or any similar document relating to any series of
Preferred Stock) that adversely affect the powers, preferences, privileges or
rights of this Series; provided, however, that the creation and issuance of any
other class or series of Preferred Stock, or any increase in the number of
authorized shares of any Preferred Stock of any other class or series, in each
case ranking on a parity with or junior to this Series with respect to the
payment of dividends and the distribution of assets upon liquidation,
dissolution or winding up of the affairs of the Corporation shall not be deemed
to adversely affect such powers, preferences or other special rights.

         (c) Unless the vote or consent of the holders of a greater number of
shares shall then be required by law, the approval of the holders of at least
two-thirds of all of the then-outstanding shares of this Series and all other
series of preferred stock ranking on a parity with shares of this Series, either
as to dividends or upon liquidation, given in person or by proxy, either in
writing or by a vote at a meeting called for the purpose at which the holders of
shares of this Series and such other series of Preferred Stock shall vote
together as a single class without regard to series, shall be necessary for
authorizing, effecting or validating (i) the creation, authorization or issuance
of, (ii) the reclassification of any authorized stock of the Corporation into,
or (iii) the creation, authorization or issuance of any obligation or security
convertible into or evidencing the right to purchase, any additional class or
series of stock ranking prior to this Series, either as to dividends or upon
liquidation.

         (d) (i) If at any time dividends on this Series shall be in arrears in
an amount equal to six quarterly dividends thereon, the occurrence of such
contingency shall mark the beginning of a period (herein called a "default
period") which shall extend until such time as all accrued and unpaid dividends
for all previous dividend periods and for the current dividend period on all
shares of this Series then outstanding shall have been declared and paid or set
apart for payment.
<PAGE>
                                                                          8

During each default period, the holders of shares of this Series and other
shares of Preferred Stock on which dividends are in arrears and as to which
similar voting rights have been conferred, voting as a class, irrespective of
series, shall have the right to elect two Directors to the Board of Directors of
the Corporation.

                  (ii) During any default period, such voting right of the
         holders of this Series may be exercised by written consent, at a
         special meeting called pursuant to Section 7(d)(iii) hereof or at any
         annual meeting of stockholders. The absence of a quorum of the holders
         of Common Stock at any such special or annual meeting shall not affect
         the exercise by the holders of Preferred Stock of such voting right. At
         any meeting at which the holders of Preferred Stock shall exercise such
         voting right initially during an existing default period, they shall
         have the right, voting as a class, to elect Directors to fill such
         vacancies, if any, in the Board of Directors as may then exist up to
         two Directors or, if such right is exercised at an annual meeting, to
         elect two Directors. If the number which may be so elected at any
         special meeting does not amount to the required number, the holders of
         Preferred Stock shall have the right to make such increase in the
         number of Directors as shall be necessary to permit the election by
         them of the required number. After the holders of the Preferred Stock
         shall have exercised their right to elect Directors in any default
         period and during the continuance of such period, the number of
         Directors shall not be increased or decreased except by vote of the
         holders of Preferred Stock as herein provided. Any Director elected by
         a vote of the holders of Preferred Stock may be removed from office,
         with or without cause, only by the affirmative vote of the requisite
         percentage of holders of Preferred Stock required to elect Directors as
         specified in this Section 7(d).

                  (iii) Unless the holders of Preferred Stock, during an
         existing default period, shall have previously exercised their right to
         elect Directors, the Board of Directors may order, or any shareholder
         or shareholders owning in the aggregate not less than ten percent (10%)
         of the total number of shares of Preferred Stock outstanding,
         irrespective of series, on which dividends are in arrears and as to
         which similar voting rights have been conferred, may request, the
         calling of a special meeting of the holders of Preferred Stock, which
         meeting shall thereupon be called by the Chairman, a Vice Chairman or
         the Secretary of the Corporation. Notice of such meeting and of any
         annual meeting at which holders of Preferred Stock are entitled to vote
         pursuant to this Section 7(d)(iii) shall be given to each holder of
         record of Preferred Stock entitled to vote thereat by mailing a copy of
         such notice to him at his last address as the same appears on the books
         of the Corporation on such record date, not more than 45 days prior to
         the date of such notice, as the Board of Directors may fix for this
         purpose. Such meeting shall be called for a time not earlier than 10
         days and not later than 60 days after such order or request or, in
         default of the calling of such meeting within 60 days after such order
         or request, such meeting may be called on similar notice by any
         shareholder or shareholders owning in the aggregate not less than 10%
         of the total number of shares of Preferred Stock outstanding,
         irrespective of series, entitled to vote thereat.

                  (iv) In any default period the holders of Common Stock, and
         other classes of stock of the Corporation if applicable, shall continue
         to be entitled to elect the whole number of Directors constituting the
         Board of Directors until the holders of Preferred Stock, voting as a
         class, shall have exercised their right to elect two Directors, after

                                BANK UNITED CORP.

                      ------------------------------------

                         Pursuant to Section 151 of the
                General Corporation Law of the State of Delaware
                      ------------------------------------

          BANK UNITED CORP., a corporation organized and existing under the laws
of the State of Delaware (the "Corporation"), HEREBY CERTIFIES that the
following resolutions were duly adopted by the Board of Directors of the
Corporation on August 5, 1999, pursuant to authority conferred upon the Board of
Directors by the provisions of the Restated Certificate of Incorporation of the
Corporation which authorize the issuance of up to 10,000,000 shares of preferred
stock of $0.01 par value per share (the "Preferred Stock"):

                  RESOLVED that, pursuant to resolutions of the Board of
Directors of Bank United Corp. (the "Corporation") adopted on August 5, 1999,
the issue of 2,300,000 shares of Series B Preferred Stock, $50 liquidation
preference per share ($0.01 par value), is hereby authorized and the
designation, preferences and privileges, voting rights, relative, participating,
optional and other special rights, and qualifications, limitations and
restrictions of all 2,300,000 shares of such Series, in addition to those set
forth in the Restated Certificate of Incorporation of the Corporation, are
hereby fixed as follows:

         1. Designation. The designation of this Series shall be Series B
Preferred Stock (hereinafter referred to as this "Series"), and the number of
shares constituting this Series shall be 2,300,000. Shares of this Series shall
have a liquidation preference of $50. The number of authorized shares of this
Series may be reduced (but not below the number then issued and outstanding) by
further resolution duly adopted by the Board of Directors of the Corporation or
by any duly authorized committee of the Board of Directors (collectively, the
"Board of Directors") and by the filing of a certificate pursuant to the
provisions of the General Corporation Law of the State of Delaware stating that
such reduction has been so authorized, but the number of authorized shares of
this Series shall not be increased.

         2. Dividends. (a) The holders of shares of this Series shall be
entitled to receive cash dividends, when, as and if declared by the Board of
Directors, out of funds legally available for that purpose, at the rates set
forth below in this Section 2. Dividends on the shares of this Series


<PAGE>
                                                                       2

shall be payable, when, as and if declared by the Board of Directors, quarterly
in arrears on February 16, May 16, August 16 and November 16 of each year (each,
a "Dividend Payment Date"), commencing on November 16, 1999, or if such date is
not a Business Day (as defined below), the next succeeding Business Day. Each
such dividend shall be paid to the holders of record of shares of this Series as
they appear on the stock register of the Corporation on the applicable Record
Date, as shall be fixed by the Board of Directors; provided, however, that
holders of shares of this Series called for redemption on a Redemption Date
falling between the record date associated with a Dividend Payment Date and such
Dividend Payment Date shall receive the applicable dividend payment, together
with all other accumulated and unpaid dividends on such date as shall be fixed
for redemption. Dividends on the shares of this Series shall accumulate and be
cumulative from the date of original issuance. "Business Day" shall mean any day
other than a Saturday or Sunday or a day on which banking institutions in New
York City are authorized or required by law or executive order to remain closed.

         (b) For each quarterly dividend period (each, a "Dividend Period") from
August 10, 1999 through and including the Dividend Period ending August 16,
2002, dividends payable on the shares of this Series shall be payable at a rate
per annum of the liquidation preference thereof equal to 7.25% (the "Initial
Rate Period"). For each Dividend Period after the Initial Rate Period, dividends
payable on the shares of this Series shall be payable at a rate per annum of the
liquidation preference thereof equal to the Reset Rate (as defined below). The
amount of dividends per share for each Dividend Period shall be computed by
dividing the applicable rate for such Dividend Period by four and applying the
resulting rate to the liquidation preference per share of this Series. Each
Dividend Period (other than the Initial Dividend Period) shall commence on a
Dividend Payment Date and shall end on and include the day next preceding the
next Dividend Payment Date.

         (c) Dividends payable on this Series for any period greater or less
than a full Dividend Period, other than the Initial Dividend Period, shall be
computed on the basis of a 360-day year consisting of twelve 30-day months and,
for any period less than one month, the actual number of days elapsed in the
period.

         (d) No full dividends shall be declared or paid or set apart for
payment on the Preferred Stock of any series ranking, as to dividends, on a
parity with or junior to this Series for any period unless full cumulative
dividends on the shares of this Series for all full Dividend Periods ending on
or prior to the date of such dividends on such other series of Preferred Stock
have been or contemporaneously are declared and paid or declared and a sum
sufficient for the payment thereof set apart for such payment. When dividends
are not paid in full, as aforesaid, upon the shares of this Series and any other
series of Preferred Stock ranking on a parity as to dividends with this Series,
all dividends declared upon shares of this Series and any other series of
Preferred Stock ranking on a parity as to dividends with this Series shall be
declared pro rata so that the amount of dividends declared per share on this
Series and such other Preferred Stock shall in all cases bear to each other the
same ratio that accrued and unpaid dividends per share on the shares of this
Series and such other Preferred Stock bear to each other. No interest, or sum of

                                                                           3

money in lieu of interest, shall be payable in respect of any dividend payment
or payments on this Series which may be in arrears.

         (e) So long as any shares of this Series are outstanding, no dividend
(other than a dividend in Common Stock or in any other stock ranking junior to
this Series as to dividends and upon liquidation and other than as provided in
paragraph (d) of this Section 2) shall be declared or paid or set aside for
payment or other distribution declared or made upon the Common Stock or upon any
other stock ranking junior to or on a parity with this Series as to dividends or
upon liquidation, nor shall any Common Stock or any other stock of the
Corporation ranking junior to or on a parity with this Series as to dividends or
upon liquidation be redeemed, purchased or otherwise acquired for any
consideration (or any moneys be paid to or made available for a sinking fund for
the redemption of any shares of any such stock) by the Corporation (except by
conversion into or exchange for stock of the Corporation ranking junior to this
Series as to dividends and upon liquidation), unless, in each case, full
cumulative dividends on all outstanding shares of this Series for all full
Dividend Periods ending on or prior to the date of such other dividend,
distribution, redemption, purchase or other acquisition, shall have been or
contemporaneously are paid or declared and a sum sufficient for the payment
thereof set aside for such payment.

         3. Remarketing. (a) The dividend rate on this Series shall be reset to
the Reset Rate on the Purchase Contract Settlement Date (as defined below). The
Corporation shall request, not later than 15 nor more than 30 calendar days
prior to the Remarketing Date (as defined below), that the Depositary (as
defined below) notify the Holders of shares of this Series and the holders of
Corporate PIES of the Remarketing and of the procedures that must be followed if
a Holder of Corporate PIES wishes to make a cash settlement of its obligation to
purchase Common Stock of the Corporation pursuant to the Purchase Contract
Agreement.

                  (b) Not later than 5:00 p.m., New York City time, on the
seventh Business Day preceding the Purchase Contract Settlement Date, each
Holder may elect to have the shares of this Series held by such Holder
remarketed in the Remarketing. Holders of Corporate PIES that do not give notice
of their intention to make a cash settlement of the purchase contract component
of their Corporate PIES prior to such time in the manner specified in the
Purchase Contract Agreement, or that give such notice but fail to deliver cash
prior to 11:00 a.m., New York City time, on or prior to the fifth Business Day
preceding the Purchase Contract Settlement Date, shall be deemed to have
consented to the disposition of the shares of this Series that are a component
of their Corporate PIES in the Remarketing. Holders of the shares of this Series
that are not a component of Corporate PIES wishing to have their shares of this
Series remarketed shall give to the Purchase Contract Agent notice of their
election prior to 11:00 a.m., New York City time on such fifth Business Day. Any
such notice shall be irrevocable and may not be conditioned upon the level at
which the Reset Rate is established in the Remarketing. Promptly after 11:00
a.m., New York City time, on such fifth Business Day, the Purchase Contract
Agent, based on the notices received by it prior to such time (including notices
from the Purchase Contract Agent as to purchase contracts for which cash
settlement has been elected and cash received), shall notify the Remarketing
Agent of the number of shares of this Series to be tendered for purchase in the
Remarketing.

                                                                            4

                  (c) If any Holder of shares of this Series does not give a
notice of its intention to make a cash settlement or gives such notice but fails
to deliver cash as described in Section 3(b) above, or gives a notice of
election to have shares of this Series that are not a component of Corporate
PIES remarketed, then the shares of this Series of such Holder shall be deemed
tendered for purchase in the Remarketing, notwithstanding any failure by such
Holder to deliver or properly deliver such shares to the Remarketing Agent for
purchase.

                  (d) The right of each Holder to have shares of this Series
tendered for purchase shall be limited to the extent that (i) the Remarketing
Agent conducts a remarketing pursuant to the terms of the Remarketing Agreement,
(ii) the shares of this Series tendered have not been called for redemption,
(iii) the Remarketing Agent is able to find a purchaser or purchasers for the
tendered shares of this Series and (iv) such purchaser or purchasers deliver the
purchase price therefor to the Remarketing Agent.

                  (e) On the Remarketing Date, the Remarketing Agent shall use
commercially reasonable efforts to remarket, at a price equal to 100.50% of the
aggregate liquidation preference thereof, the shares of this Series tendered or
deemed tendered for purchase.

                  (f) If, as a result of the efforts described in Section 3(e),
the Remarketing Agent determines that it will be able to remarket all of the
shares of this Series tendered or deemed tendered for purchase at a price of
100.50% of the aggregate liquidation preference of such shares prior to 4:00
p.m., New York City time, on the Remarketing Date, the Remarketing Agent shall
determine the Reset Rate, which shall be the rate per annum (rounded to the
nearest one-thousandth (0.001) of one percent per annum) that the Remarketing
Agent determines, in its sole judgment, to be the lowest rate per annum that
will enable it to remarket all of the shares of this Series tendered or deemed
tendered for Remarketing.

                  (g) If none of the Holders of the shares of this Series or the
holders of the Corporate PIES elects to have shares of this Series remarketed in
the Remarketing, the Reset Rate shall be the rate determined by the Remarketing
Agent, in its sole discretion, as the rate that would have been established had
a Remarketing of all the shares of this Series been held on the Remarketing
Date.

                  (h) If, by 4:00 p.m., New York City time, on the Remarketing
Date, the Remarketing Agent is unable to remarket all of the Preferred
Securities tendered or deemed tendered for purchase, a "Failed Remarketing"
shall be deemed to have occurred and the Remarketing Agent shall so advise by
telephone the Depositary and the Corporation. In the event of a Failed
Remarketing, the Reset Rate shall equal (1) the "AA" Composite Commercial Paper
Rate (as defined below), plus (2) the Applicable Margin (as defined below).

Remarketing Date, provided that there has not been a Failed Remarketing, the
Remarketing Agent shall advise, by telephone (i) the Depositary and the

of the Depositary.

                  (j) In accordance with the Depositary's normal procedures, on
the Purchase Contract Settlement Date, the transactions described above with
respect to each Preferred Security tendered for purchase and sold in the
Remarketing shall be executed through the Depositary, and the accounts of the
respective Depositary Participants shall be debited and credited and such shares
of this Series delivered by book-entry as necessary to effect purchases and
sales of such shares of this Series. The Depositary shall make payment in
accordance with its normal procedures.

                  (k) If any Holder of shares of this Series selling shares of
this Series in the Remarketing fails to deliver such shares, the Depositary
Participant of such selling holder and of any other Person that was to have
purchased shares of this Series in the Remarketing may deliver to any such other
Person a number of shares of this Series that is less than the number of shares
of this Series that otherwise was to be purchased by such Person. In such event,
the number of shares of this Series to be so delivered shall be determined by
such Depositary Participant, and delivery of such lesser number of shares of
this Series shall constitute good delivery.

                  (l) Under the Remarketing Agreement, the Corporation shall be
liable for, and shall pay, any and all costs and expenses incurred in connection
with the Remarketing.

                  (m) The tender and settlement procedures set in this Section
3, including provisions for payment by purchasers of the shares of this Series
in the Remarketing, shall be subject to modification to the extent required by
the Depositary or if the book-entry system is no longer available for the shares
of this Series at the time of the Remarketing, to facilitate the tendering and
remarketing of the shares of this Series in certificated form. In addition, the
Remarketing Agent may modify the settlement procedures set forth herein in order

         (c)      Redemption Procedures.

                   (i) In the event that, pursuant to paragraph (a) above, fewer
         than all the outstanding shares of this Series are to be redeemed, the
         number of shares to be redeemed shall be determined by the Board of
         Directors and the shares to be redeemed shall be determined by lot or
         pro rata as may be determined by the Board of Directors or by any other
         method as may be determined by the Board of Directors in its sole
         discretion to be equitable, provided that such method satisfies any
         applicable requirements of any securities exchange on which this Series
         is listed.

                  (ii) In the event the Corporation shall redeem shares of this
         Series, notice of such redemption shall be given by first class mail,
         postage prepaid, mailed not less than 30 or more than 60 days prior to
         the redemption date, to each holder of record of the shares to be
         redeemed, at such holder's address as the same appears on the stock
         register of the Corporation. Each such notice shall state: (i) the
         redemption date; (ii) the number of shares of this Series to be
         redeemed and, if fewer than all the shares held by such holder are to
         be redeemed, the number of such shares to be redeemed from such holder;
         (iii) the redemption price; (iv) the place or places where certificates
         for such shares are to
<PAGE>
                                                                          9

         be surrendered for payment of the redemption price; and (v) that
         dividends on the shares to be redeemed shall cease
         to accrue on the redemption date.

                  (iii) Notice having been mailed as aforesaid, from and after
         the redemption date (unless default shall be made by the Corporation in
         providing money for the payment of the redemption price) dividends on
         the shares of this Series so called for redemption shall cease to
         accrue, and said shares shall no longer be deemed to be outstanding,
         and all rights of the holders thereof as stockholders of the
         Corporation (except the right to receive from the Corporation the
         redemption price) shall cease. Upon surrender in accordance with said
         notice of the certificates for any shares so redeemed (properly
         endorsed or assigned for transfer, if the Board of Directors shall so
         require and the notice shall so state), such shares shall be redeemed
         by the Corporation at the redemption price aforesaid. In case fewer
         than all the shares represented by any such certificate are redeemed, a
         new certificate shall be issued representing the unredeemed shares
         without cost to the holder thereof.

                  (iv) Any shares of this Series which shall at any time have
         been redeemed shall, after such redemption, have the status of
         authorized but unissued shares of Preferred Stock, without designation
         as to series until such shares are once more designated as part of a
         particular series by the Board of Directors.

                  (v) Notwithstanding the foregoing provisions of this Section
         4, if full cumulative dividends on all outstanding shares of this
         Series are in arrears, no shares of this Series shall be redeemed
         unless all outstanding shares of this Series are simultaneously
         redeemed, and the Corporation shall not purchase or otherwise acquire
         any shares of this Series; provided, however, that the foregoing shall
         not prevent the purchase or acquisition of shares of this Series
         pursuant to a purchase or exchange offer made on the same terms to
         holders of all outstanding shares of this Series.

         5. Conversion. The holders of shares of this Series shall not have any
rights to convert such shares into shares of any other class or series of
capital stock of the Corporation.

         6. Liquidation Rights. (a) Upon the voluntary or involuntary
dissolution, liquidation or winding up of the Corporation, the holders of the
shares of this Series shall be entitled to receive and to be paid out of the
assets of the Corporation available for distribution to its stockholders, before
any payment or distribution shall be made on the Common Stock or on any other
class of stock ranking junior to this Series upon liquidation, the amount of $50
per share, plus accrued and unpaid cumulative dividends (whether or not
declared) to the date of the liquidating distribution.

         (b) After the payment to the holders of the shares of this Series of
the full preferential amounts provided for in this Section 6, the holders of
this Series as such shall have no right or claim to any of the remaining assets
of the Corporation.

                                                                         10

         (c) If, upon any voluntary or involuntary dissolution, liquidation, or
winding up of the Corporation, the amounts payable with respect to the shares of
this Series and any other shares of stock of the Corporation ranking as to any
such distribution on a parity with the shares of this Series are not paid in
full, the holders of the shares of this Series and of such other shares shall
share ratably in any such distribution of assets of the Corporation in
proportion to the full respective distributions to which they are entitled.

         (d) Neither the sale of all or substantially all the property or
business of the Corporation, nor the merger or consolidation of the Corporation
into or with any other corporation or the merger or consolidation of any other
corporation into or with the Corporation, shall be deemed to be a dissolution,
liquidation or winding up, voluntary or involuntary, for the purposes of this
Section 6.

         7.       Ranking.  For purposes of this resolution, any stock of
any class or classes of the Corporation shall be deemed to rank:

         (a) prior to the shares of this Series, either as to dividends or upon
liquidation, if the holders of such class or classes shall be entitled to the
receipt of dividends or of amounts distributable upon dissolution, liquidation
or winding up of the Corporation, as the case may be, in preference or priority
to the holders of shares of this Series;

         (b) on a parity with shares of this Series, either as to dividends or
upon liquidation, whether or not the dividend rates, dividend payment dates or
redemption or liquidation prices per share or sinking fund provisions, if any,
be different from those of this Series (and whether or not such dividends shall
accumulate), if the holders of such stock shall be entitled to the receipt of
dividends or of amounts distributable upon dissolution, liquidation or winding
up of the Corporation, as the case may be, without preference or priority, one
over the other, as between the holders of such stock and the holders of shares
of this Series; and

         (c) junior to shares of this Series, either as to dividends or upon
liquidation, if such class shall be Common Stock or if the holders of shares of
this Series shall be entitled to receipt of dividends or of amounts
distributable upon dissolution, liquidation or winding up of the Corporation, as
the case may be, in preference or priority to the holders of shares of such
class or classes.

         (d) The shares of Series A Preferred Stock of the Corporation shall
rank on a parity with the shares of this Series.

         8. Voting Rights. The holders of the shares of this Series shall have
the following voting rights:

         (a) Each share of this Series will have the right to vote, with each
share of this Series having 0.10 vote, in connection with matters submitted
generally to the holders of the common stock and other capital stock of the
Corporation entitled to vote in respect of matters submitted to

<PAGE>
                                                                              11

the stockholders of the Corporation generally. For these purposes, the holders
of the shares of this Series and the holders of the common stock and such other
capital stock of the Corporation, so entitled to vote, shall vote as a single
class.

         (b) Unless the vote or consent of the holders of a greater number of
shares shall then be required by law, the approval of the holders of at least
two-thirds of the then-outstanding shares of this Series, given in person or by
proxy, either in writing or by a vote at a meeting called for the purpose at
which the holders of shares of this Series shall vote together as a separate
class, shall be required for authorizing, effecting or validating any amendment,
alteration or repeal, whether by merger, consolidation or otherwise, of any of
the provisions of the Restated Certificate of Incorporation of the Corporation
or of any certificate amendatory thereof or supplemental thereto (including any
Certificate of Designations or any similar document relating to any series of
Preferred Stock) that adversely affect the powers, preferences, privileges or
rights of this Series; provided, however, that the creation and issuance of any
other class or series of preferred stock, or any increase in the number of
authorized shares of any Preferred Stock of any other class or series, in each
case ranking on a parity with or junior to this Series with respect to the
payment of dividends and the distribution of assets upon liquidation,
dissolution or winding up of the affairs of the Corporation shall not be deemed
to adversely affect such powers, preferences or other special rights.

         (c) Unless the vote or consent of the holders of a greater number of
shares shall then be required by law, the approval of the holders of at least
two-thirds of all of the then-outstanding shares of this Series and all other
series of preferred stock ranking on a parity with shares of this Series, either
as to dividends or upon liquidation, given in person or by proxy, either in
writing or by a vote at a meeting called for the purpose at which the holders of
shares of this Series and such other series of Preferred Stock shall vote
together as a single class without regard to series, shall be necessary for
authorizing, effecting or validating (i) the creation, authorization or issuance
of, (ii) the reclassification of any authorized stock of the Corporation into,
or (iii) the creation, authorization or issuance of any obligation or security
convertible into or evidencing the right to purchase, any additional class or
series of stock ranking prior to this Series, either as to dividends or upon
liquidation.

         (d) (i) If at any time dividends on this Series shall be in arrears in
an amount equal to six quarterly dividends thereon, the occurrence of such
contingency shall mark the beginning of a period (herein called a "default
period") which shall extend until such time as all accrued and unpaid dividends
for all previous dividend periods and for the current dividend period on all
shares of this Series then outstanding shall have been declared and paid or set
apart for payment. During each default period, the holders of shares of this
Series and other shares of Preferred Stock on which dividends are in arrears and
as to which similar voting rights have been conferred, voting as a class,
irrespective of series, shall have the right to elect two Directors to the Board
of Directors of the Corporation.

             (ii)   During any default period, such voting right of the
         holders of this Series may be exercised by written consent, at a
         special meeting called pursuant to Section

<PAGE>

                                                                         12

         7(d)(iii) hereof or at any annual meeting of stockholders.
         The absence of a quorum of the holders of Common Stock at
         any such special or annual meeting shall not affect the exercise
         by the holders of Preferred Stock of such voting right. At
         any meeting at which the holders of Preferred Stock shall exercise such
         voting right initially during an existing default period, they shall
         have the right, voting as a class, to elect Directors to fill such
         vacancies, if any, in the Board of Directors as may then exist up to
         two Directors or, if such right is exercised at an annual meeting, to
         elect two Directors. If the number which may be so elected at any
         special meeting does not amount to the required number, the holders of
         Preferred Stock shall have the right to make such increase in the
         number of Directors as shall be necessary to permit the election by
         them of the required number. After the holders of the Preferred Stock
         shall have exercised their right to elect Directors in any default
         period and during the continuance of such period, the number of
         Directors shall not be increased or decreased except by vote of the
         holders of Preferred Stock as herein provided. Any Director elected by
         a vote of the holders of Preferred Stock may be removed from office,
         with or without cause, only by the affirmative vote of the requisite
         percentage of holders of Preferred Stock required to elect Directors as
         specified in this Section 8(d).

                  (iii) Unless the holders of Preferred Stock, during an
         existing default period, shall have previously exercised their right to
         elect Directors, the Board of Directors may order, or any shareholder
         or shareholders owning in the aggregate not less than ten percent (10%)
         of the total number of shares of Preferred Stock outstanding,
         irrespective of series, on which dividends are in arrears and as to
         which similar voting rights have been conferred, may request, the
         calling of a special meeting of the holders of Preferred Stock, which
         meeting shall thereupon be called by the Chairman, a Vice Chairman or
         the Secretary of the Corporation. Notice of such meeting and of any
         annual meeting at which holders of Preferred Stock are entitled to vote
         pursuant to this Section 7(d)(iii) shall be given to each holder of
         record of Preferred Stock entitled to vote thereat by mailing a copy of
         such notice to him at his last address as the same appears on the books
         of the Corporation on such record date, not more than 45 days prior to
         the date of such notice, as the Board of Directors may fix for this
         purpose. Such meeting shall be called for a time not earlier than 10
         days and not later than 60 days after such order or request or, in
         default of the calling of such meeting within 60 days after such order
         or request, such meeting may be called on similar notice by any
         shareholder or shareholders owning in the aggregate not less than 10%
         of the total number of shares of Preferred Stock outstanding,
         irrespective of series, entitled to vote thereat.

                  (iv) In any default period the holders of Common Stock, and
         other classes of stock of the Corporation if applicable, shall continue
         to be entitled to elect the whole number of Directors constituting the
         Board of Directors until the holders of Preferred Stock, voting as a
         class, shall have exercised their right to elect two Directors, after
         the exercise of which right (A) the Directors so elected by the holders
         of Preferred Stock shall continue in office until their successors
         shall have been elected by such holders or until the expiration of the
         default period, and (B) any vacancy on the Board of Directors
<PAGE>
                                                                         13

         may(except as provided in Section 8(d)(ii) hereof) be filled by vote
         of a majority of the remaining Directors theretofore elected by the
         holders of the class of stock which elected the Director whose office
         shall have become vacant. References in this Section 8(d) to Directors
         elected by the holders of a particular class of stock shall include
         Directors elected by such Directors to fill vacancies as provided in
         clause (B) of the foregoing sentence.

                  (v) Immediately upon the expiration of a default period, (A)
         the right of the holders of Preferred Stock as a class to elect
         Directors shall cease, (B) the term of any Directors elected by the
         holders of Preferred Stock as a class shall terminate, and (C) the
         number of Directors shall be such number as may be provided for in the
         Restated Certificate of Incorporation or Bylaws of the Corporation or
         by resolution of the Board of Directors, irrespective of any increase
         made pursuant to the provisions of Section 8(d)(ii) hereof (such number
         being subject, however, to change thereafter in any manner provided by
         law or in the Restated Certificate of Incorporation or Bylaws of the
         Corporation). Any vacancies on the Board of Directors effected by the
         provisions of clauses (B) and (C) in the preceding sentence may be
         filled by a majority of the remaining Directors.

         (e) Except as set forth herein or required by applicable law, holders
of shares of this Series shall have no voting rights and their consent shall not
be required for taking any corporate action.

the Purchase Contract comprising a portion of such Corporate PIES.

                 (FORM OF REVERSE OF CORPORATE PIES CERTIFICATE)


     Each Purchase Contract evidenced hereby is governed by a Purchase Contract
Agreement, dated as of August 10, 1999 (as may be supplemented from time to
time, the "Purchase Contract Agreement"), between the Company and The First
National Bank of Chicago, as Purchase Contract Agent (including its successors
hereunder, the "Agent"), to which Purchase Contract Agreement and supplemental
agreements thereto reference is hereby made for a description of the respective
rights, limitations of rights, obligations, duties and immunities thereunder of
the Agent, the Company, and the Holders and of the terms upon which the
Corporate PIES Certificates are, and are to be, executed and delivered.

     Each Purchase Contract evidenced hereby obligates the Holder of this
Corporate PIES Certificate to purchase, and the Company to sell, on the Purchase
Contract Settlement Date at a price equal to the Stated Amount (the "Purchase
Price"), a number of shares of Common Stock of the Company equal to the
Settlement Rate, unless, on or prior to the Purchase Contract Settlement Date,
there shall have occurred a Termination Event with respect to the Security of
which such Purchase Contract is a part or an Early Settlement shall have
occurred. The "Settlement Rate" is equal to (a) if the Applicable Market Value
(as defined below) is equal to or greater than $44.9250 (the "Threshold
Appreciation Price"), 1.11297 shares of Common Stock per Purchase Contract, (b)
if the Applicable Market Value is less than the Threshold Appreciation Price but
is greater than $37.4375 the number of shares of Common Stock per Purchase
Contract equal to the Stated Amount divided by the Applicable Market Value and
(c) if the Applicable Market Amount is less than or equal to $37.4375, 1.33556
shares of Common Stock per Purchase Contract, in each case subject to adjustment
as provided in the Purchase Contract Agreement. No fractional shares of Common
Stock will be issued upon settlement of Purchase Contracts, as provided in the
Purchase Contract Agreement.

     Each Purchase Contract evidenced hereby, which is settled either through
Early Settlement or Cash Settlement, shall obligate the Holder of the related
Corporate PIES to purchase at the Purchase Price, and the Company to sell, a
number of newly issued shares of Common Stock equal to the Early Settlement Rate
or the Settlement Rate, as applicable.

     The "Applicable Market Value" means the average of the Closing Price per
share of Common Stock on each of the 20 Trading Days ending on the third Trading
Day immediately preceding the Purchase Contract Settlement Date. The "Closing
Price" of the Common Stock on any date of determination means (i) the closing
sale price (or, if no closing price is reported, the last reported sale price)
of the Common Stock on the Nasdaq National Market on such date, (ii) if the
Common Stock is not listed for trading on the Nasdaq National Market on any such
date, the closing sale price as reported in the composite transactions for the
principal United States securities exchange on which the Common Stock is so
listed, (iii) if the Common Stock is not so reported, the last quoted bid price
for the Common Stock in the over-the-counter market as reported by the National
Quotation Bureau or similar organization or (iv) if such bid price is not
available, the average of the mid-point of the last bid and ask prices of the
Common Stock on such date from at least three nationally recognized independent
investment banking firms

<PAGE>
                                                                          6



retained for this purpose by the Company. A "Trading Day" means a day on
which the Common Stock (A) is not suspended from trading on any national or
regional securities exchange or association or over-the-counter market at the
close of business and (B) has traded at least once on the national or regional
securities exchange or association or over-the-counter market that is the
primary market for the trading of the Common Stock.

     In accordance with the terms of the Purchase Contract Agreement, the Holder
of this Corporate PIES Certificate may pay the Purchase Price for the shares of
Common Stock purchased pursuant to each Purchase Contract evidenced hereby by
effecting a Cash Settlement or an Early Settlement or a remarketing of the
related Pledged Preferred Stock. A Holder of Corporate PIES who does not effect,
on or prior to 11:00 a.m. New York City time on the fifth Business Day
immediately preceding the Purchase Contract Settlement Date, an effective Cash
Settlement or an Early Settlement, shall pay the Purchase Price for the shares
of Common Stock to be issued under the related Purchase Contract from the
proceeds of the sale of the related Pledged Preferred Stock held by the
Collateral Agent. Such sale will be made by the Remarketing Agent pursuant to
the terms of the Remarketing Agreement on the third Business Day prior to the
Purchase Contract Settlement Date. If, as provided in the Purchase Contract
Agreement, upon the occurrence of a Failed Remarketing the Collateral Agent, for
the benefit of the Company, exercises its rights as a secured creditor with
respect to the Pledged Preferred Stock related to this Corporate PIES
certificate, any accrued and unpaid dividends on such Pledged Preferred Stock
will become payable by the Company to the holder of this Corporate PIES
Certificate in the manner provided for in the Purchase Contract Agreement.

     The Company shall not be obligated to issue any shares of Common Stock in
respect of a Purchase Contract or deliver any certificates therefor to the
Holder unless it shall have received payment of the aggregate purchase price for
the shares of Common Stock to be purchased thereunder in the manner herein set
forth.

     Each Purchase Contract evidenced hereby and all obligations and rights of
the Company and the Holder thereunder shall terminate if a Termination Event
shall occur. Upon the occurrence of a Termination Event, the Company shall give
written notice to the Agent and to the Holders, at their addresses as they
appear in the Corporate PIES Register. Upon and after the occurrence of a
Termination Event, the Collateral Agent shall release the Pledged Preferred
Stock forming a part of each Corporate PIES from the Pledge. A Corporate PIES
shall thereafter represent the right to receive the Preferred Stock forming a
part of such Corporate PIES in accordance with the terms of the Purchase
Contract Agreement and the Pledge Agreement.

     Under the terms of the Pledge Agreement, the Agent will be entitled to
exercise the voting and any other consensual rights pertaining to the Pledged
Preferred Stock. Upon receipt of notice of any meeting at which holders of
Preferred Stock are entitled to vote or upon the solicitation of consents,
waivers or proxies of holders of Preferred Stock, the Agent shall, as soon as
practicable thereafter, mail to the Corporate PIES Holders a notice (a)
containing such information as is contained in the notice or solicitation, (b)
stating that each Corporate PIES Holder on the record date set by the Agent
therefor (which, to the extent possible, shall be the same date as the record
date for determining the holders of Preferred Stock entitled to vote) shall

<PAGE>
                                                                          7


be entitled to instruct the Agent as to the exercise of the voting rights
pertaining to the Preferred Stock constituting a part of such Holder's Corporate
PIES and (c) stating the manner in which such instructions may be given. Upon
the written request of the Corporate PIES Holders on such record date, the Agent
shall endeavor insofar as practicable to vote or cause to be voted, in
accordance with the instructions set forth in such requests, the maximum
aggregate liquidation preference of Preferred Stock as to which any particular
voting instructions are received. In the absence of specific instructions from
the Holder of a Corporate PIES, the Agent shall abstain from voting the
Preferred Stock evidenced by such Corporate PIES.

     The Corporate PIES Certificates are issuable only in registered form and
only in denominations of a single Corporate PIES and any integral multiple
thereof. The transfer of any Corporate PIES Certificate will be registered and
Corporate PIES Certificates may be exchanged as provided in the Purchase
Contract Agreement. The Corporate PIES Registrar may require a Holder, among
other things, to furnish appropriate endorsements and transfer documents
permitted by the Purchase Contract Agreement. No service charge shall be
required for any such registration of transfer or exchange, but the Company and
the Agent may require payment of a sum sufficient to cover any tax or other
governmental charge payable in connection therewith. A holder who elects to
substitute a Treasury Security for Preferred Stock thereby creating Treasury
PIES, shall be responsible for any fees or expenses payable in connection
therewith. Except as provided in the Purchase Contract Agreement, for so long as
the Purchase Contract underlying a Corporate PIES remains in effect, such
Corporate PIES shall not be separable into its constituent parts, and the rights
and obligations of the Holder of such Corporate PIES in respect of the Preferred
Stock and Purchase Contract constituting such Corporate PIES may be transferred
and exchanged only as a Corporate PIES. The holder of a Corporate PIES may
substitute for the Pledged Preferred Stock securing its obligation under the
related Purchase Contract Treasury Securities in an aggregate principal amount
equal to the aggregate liquidation preference of the Pledged Preferred Stock in
accordance with the terms of the Purchase Contract Agreement and the Pledge
Agreement. From and after such Collateral Substitution, the Security for which
such Pledged Treasury Securities secures the holder's obligation under the
Purchase Contract shall be referred to as a "Treasury PIES." A Holder may make
such Collateral Substitution only in integral multiples of 20 Corporate PIES for
20 Treasury PIES. Such Collateral Substitution may cause the equivalent
aggregate amount of this Certificate to be increased or decreased; provided,
however, this Corporate PIES Certificate shall not represent more than 2,000,000
Corporate PIES. All such adjustments to the equivalent amount of this Corporate
PIES Certificate shall be duly recorded by placing an appropriate notation on
the Schedule attached hereto.

     A Holder of Treasury PIES may recreate Corporate PIES by delivering to the
Securities Intermediary Preferred Stock with an aggregate liquidation preference
equal to the aggregate principal amount of the Pledged Treasury Securities in
exchange for the release of such Pledged Treasury Securities in accordance with
the terms of the Purchase Contract Agreement and the Pledge Agreement.

     The Company shall pay, on each Payment Date, the Contract Adjustment
Payments payable in respect of each Purchase Contract to the Person in whose
name the Corporate PIES Certificate evidencing such Purchase Contract is
registered at the close of business on the Record

<PAGE>
                                                                          8



Date for such Payment Date. Contract Adjustment Payments will be payable at the
office of the Agent in The City of New York or, at the option of the Company, by
check mailed to the address of the Person entitled thereto at such address as it
appears on the Corporate PIES Register.

     The Purchase Contracts and all obligations and rights of the Company and
the Holders thereunder, including, without limitation, the rights of the Holders
to receive and the obligation of the Company to pay any Contract Adjustment
Payments, shall immediately and automatically terminate, without the necessity
of any notice or action by any Holder, the Agent or the Company, if, on or prior
to the Purchase Contract Settlement Date, a Termination Event shall have
occurred. Upon the occurrence of a Termination Event, the Company shall promptly
but in no event later than two Business Days thereafter give written notice to
the Agent, the Collateral Agent and the Holders, at their addresses as they
appear in the Corporate PIES Register. Upon and after the occurrence of a
Termination Event, the Collateral Agent shall release the Preferred Stock from
the Pledge in accordance with the provisions of the Pledge Agreement.

     Subject to and upon compliance with the provisions of the Purchase Contract
Agreement, at the option of the Holder thereof, Purchase Contracts underlying
Securities may be settled early (an "Early Settlement") as provided in the
Purchase Contract Agreement. In order to exercise the right to effect Early
Settlement with respect to any Purchase Contracts evidenced by this Corporate
PIES Certificate, the Holder of this Corporate PIES Certificate shall deliver
this Corporate PIES Certificate to the Agent at the Corporate Trust Office duly
endorsed for transfer to the Company or in blank with the form of Election to
Settle Early set forth below duly completed and accompanied by payment in the
form of immediately available funds payable to the order of the Company in an
amount (the "Early Settlement Amount") equal to (i) the product of (A) the
Stated Amount times (B) the number of Purchase Contracts with respect to which
the Holder has elected to effect Early Settlement, plus (ii) if such delivery is
made with respect to any Purchase Contracts during the period from the close of
business on any Record Date for any Payment Date to the opening of business on
such Payment Date, an amount equal to the Contract Adjustment Payments payable
on such Payment Date with respect to such Purchase Contracts. Upon Early
Settlement of Purchase Contracts by a Holder of the related Securities, the
Pledged Preferred Stock underlying such Securities shall be released from the
Pledge as provided in the Pledge Agreement and the Holder shall be entitled to
receive a number of shares of Common Stock on account of each Purchase Contract
forming part of a Corporate PIES as to which Early Settlement is effected equal
to the Early Settlement Rate. The Early Settlement Rate shall initially be equal
to 1.11297 shares of Common Stock and shall be adjusted in the same manner and
at the same time as the Settlement Rate is adjusted as provided in the Purchase
Contract Agreement.

     Upon registration of transfer of this Corporate PIES Certificate, the
transferee shall be bound (without the necessity of any other action on the part
of such transferee, except as may be required by the Agent pursuant to the
Purchase Contract Agreement), under the terms of the Purchase Contract Agreement
and the Purchase Contracts evidenced hereby and the transferor shall be released
from the obligations under the Purchase Contracts evidenced by this Corporate
PIES Certificate. The Company covenants and agrees, and the Holder, by its
acceptance hereof, likewise covenants and agrees, to be bound by the provisions
of this paragraph.

                                                                         9



     The Holder of this Corporate PIES Certificate, by its acceptance hereof,
authorizes the Agent to enter into and perform the related Purchase Contracts
forming part of the Corporate PIES evidenced hereby on its behalf as its
attorney-in-fact, expressly withholds any consent to the assumption (i.e.,
affirmance) of the Purchase Contracts by the Company or its trustee in the event
that the Company becomes the subject of a case under the Bankruptcy Code, agrees
to be bound by the terms and provisions thereof, covenants and agrees to perform
his obligations under such Purchase Contracts, consents to the provisions of the
Purchase Contract Agreement, authorizes the Agent to enter into and perform the
Purchase Contract Agreement and the Pledge Agreement on its behalf as its
attorney-in-fact, and consents to the Pledge of the Shares underlying this
Corporate PIES Certificate pursuant to the Pledge Agreement. The Holder further
covenants and agrees that, to the extent and in the manner provided in the
Purchase Contract Agreement and the Pledge Agreement, but subject to the terms
thereof, Proceeds from the Remarketing with respect to any of the Pledged
Preferred Stock or security entitlements thereto in respect of the aggregate
liquidation preference of the Pledged Preferred Stock on the Purchase Contract
Settlement Date shall be paid by the Collateral Agent to the Company in
satisfaction of such Holder's obligations under such Purchase Contract and such
Holder shall acquire no right, title or interest in such payments.

     Subject to certain exceptions, the provisions of the Purchase Contract
Agreement may be amended with the consent of the Holders of a majority of the
Purchase Contracts.

     The Purchase Contracts shall for all purposes be governed by, and
construed in accordance with, the laws of the State of New York.

     The Company, the Agent and its Affiliates and any agent of the Company or
the Agent may treat the Person in whose name this Corporate PIES Certificate is
registered as the owner of the Corporate PIES evidenced hereby for the purpose
of receiving payments of dividends payable quarterly on the Preferred Stock
receiving payments of Contract Adjustment Payments, performance of the Purchase
Contracts and for all other purposes whatsoever, whether or not any payments in
respect thereof be overdue and notwithstanding any notice to the contrary, and
neither the Company, the Agent nor any such agent shall be affected by notice to
the contrary.

        The Purchase Contracts shall not, prior to the settlement thereof,
entitle the Holder to any of the rights of a holder of shares of Common Stock.

        A copy of the Purchase Contract Agreement is available for inspection at
the offices of the Agent.

                                  TREASURY PIES

        This Treasury PIES Certificate certifies that Cede & Co. is the
registered Holder of the number of Treasury PIES set forth above. Each Treasury
PIES consists of (i) a 1/20 undivided beneficial ownership interest of a
Treasury Security having a principal amount at maturity equal to $1,000, subject
to the Pledge of such Treasury Security by such Holder pursuant to the Pledge
Agreement, and (ii) the rights and obligations of the Holder under one Purchase
Contract with Bank United Corp., a Delaware corporation (the "Company"). All
capitalized terms used herein which are defined in the Purchase Contract
Agreement (as defined on the reverse hereof) have the meaning set forth therein.

        Pursuant to the Pledge Agreement, the Treasury Securities constituting
part of each Treasury PIES evidenced hereby have been pledged to the Collateral
Agent, for the benefit of the Company, to secure the obligations of the Holder
under the Purchase Contract comprising a portion of such Treasury PIES.
<PAGE>

        Each Purchase Contract evidenced hereby obligates the Holder of this
Treasury PIES Certificate to purchase, and the Company, to sell, on August 16,
2002 (the "Purchase Contract Settlement Date"), at a price equal to $50 in cash
(the "Stated Amount"), a number of Common Shares, par value $0.01 ("Common
Stock"), of the Company equal to the Settlement Rate, unless on or prior to the
Purchase Contract Settlement Date there shall have occurred a Termination Event
or an Early Settlement with respect to the Treasury PIES of which such Purchase
Contract is a part, all as provided in the Purchase Contract Agreement and more
fully described on the reverse hereof. The purchase price for the shares of
Common Stock purchased pursuant to each Purchase Contract evidenced hereby, if
not paid earlier, shall be paid on the Purchase Contract Settlement Date by
application of the Proceeds from the Treasury Securities pledged to secure the
obligations under such Purchase Contract in accordance with the terms of the
Pledge Agreement.

        The Company shall pay on each Payment Date in respect of each Purchase
Contract evidenced hereby an amount (the "Contract Adjustment Payments") equal
to (a) if a Reset Transaction has not occurred, 0.75% per annum of the Stated
Amount or (b) following the occurrence of a Reset Transaction, the Adjusted
Contract Adjustment Payment Rate related to such Reset Transaction until any
such succeeding Reset Transaction shall occur (computed on the basis of (i) for
any full quarterly period, a 360-day year of twelve 30-day months and (ii) for
any period shorter than a full quarterly period, a 30-day month and for periods
less than a month, the actual number of days elapsed per 30-day period), as the
case may be. Such Contract Adjustment Payments shall be payable to the Person in
whose name this Treasury PIES Certificate (or a Predecessor Treasury PIES
Certificate) is registered at the close of business on the Record Date for such
Payment Date.

        Contract Adjustment Payments will be payable at the office of the Agent
in The City of New York or, at the option of the Company, by check mailed to the
address of the Person entitled thereto as such address appears on the Treasury
PIES Register.

        Reference is hereby made to the further provisions 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
Agent by manual signature, this Treasury PIES Certificate shall not be entitled
to any benefit under the Pledge Agreement or the Purchase Contract Agreement or
be valid or obligatory for any purpose.

<PAGE>


                     (REVERSE OF TREASURY PIES CERTIFICATE)

        Each Purchase Contract evidenced hereby is governed by a Purchase
Contract Agreement, dated as of August 10, 1999 (as may be supplemented from
time to time, the "Purchase Contract Agreement") between the Company and The
First National Bank of Chicago, as Purchase Contract Agent (including its
successors thereunder, herein called the "Agent"), to which the Purchase
Contract Agreement and supplemental agreements thereto reference is hereby made
for a description of the respective rights, limitations of rights, obligations,
duties and immunities thereunder of the Agent, the Company and the Holders and
of the terms upon which the Treasury PIES Certificates are, and are to be,
executed and delivered.

        Each Purchase Contract evidenced hereby obligates the Holder of this
Treasury PIES Certificate to purchase, and the Company to sell, on the Purchase
Contract Settlement Date at a price equal to the Stated Amount (the "Purchase
Price") a number of shares of Common Stock of the Company equal to the
Settlement Rate, unless on or prior to the Purchase Contract Settlement Date,
there shall have occurred a Termination Event with respect to the Security of
which such Purchase Contract is a part or an Early Settlement shall have
occurred. The "Settlement Rate" is equal to (a) if the Applicable Market Value
(as defined below) is equal to or greater than $44.9250 (the "Threshold
Appreciation Price"), 1.11297 shares of Common Stock per Purchase Contract, (b)
if the Applicable Market Value is less than the Threshold Appreciation Price but
is greater than $37.4375, the number of shares of Common Stock per Purchase
Contract equal to the Stated Amount divided by the Applicable Market Value and
(c) if the Applicable Market Amount is less than or equal to $37.4375, then
1.33556 shares of Common Stock per Purchase Contract, in each case subject to
adjustment as provided in the Purchase Contract Agreement. No fractional shares
of Common Stock will be issued upon settlement of Purchase Contracts, as
provided in the Purchase Contract Agreement.

        Each Purchase Contract evidenced hereby, which is settled either through
Early Settlement or Cash Settlement, shall obligate the Holder of the related
Treasury PIES to purchase at the Purchase Price for cash, and the Company to
sell, a number of newly issued shares of Common Stock equal to the Early
Settlement Rate or the Settlement Rate, as applicable.

        The "Applicable Market Value" means the average of the Closing Prices
per share of Common Stock on each of the 20 Trading Days ending on the third
Trading Day immediately preceding the Purchase Contract Settlement Date. The
"Closing Price" of the Common Stock on any date of determination means the (i)
closing sale price (or, if no closing price is reported, the last reported sale
price) of the Common Stock on the Nasdaq National Market on such date, (ii) if
the Common Stock is not listed for trading on the Nasdaq National Market on any
such date, the closing sale price as reported in the composite transactions for
the principal United States securities exchange on which the Common Stock is so
listed, (iii) if the Common Stock is not so reported, the last quoted bid price
for the Common Stock in the over-the-counter market as reported by the National
Quotation Bureau or similar organization or (iv) if such bid price is not
available, the average of the mid-point of the last bid and ask prices of the
Common Stock on such date from at least three nationally recognized independent
investment banking firms retained for this purpose by the Company. A "Trading
Day" means a day on which the Common Stock (A) is not suspended from trading on
any national or regional securities exchange or

                              B-4
<PAGE>

association or over-the-counter market at the close of business and (B) has
traded at least once on the national or regional securities exchange or
association or over-the-counter market that is the primary market for the
trading of the Common Stock.

        In accordance with the terms of the Purchase Contract Agreement, the
Holder of this Treasury PIES shall pay the Purchase Price for the shares of
Common Stock purchased pursuant to each Purchase Contract evidenced hereby
either by effecting a Cash Settlement or an Early Settlement of each such
Purchase Contract or by applying a principal amount of the Pledged Treasury
Securities underlying such Holder's Treasury PIES equal to the Stated Amount of
such Purchase Contract to the purchase of the Common Stock. A Holder of Treasury
PIES who does not effect, on or prior to 11:00 a.m. New York City time on the
Business Day immediately preceding the Purchase Contract Settlement Date, an
effective Cash Settlement or an Early Settlement, shall pay the Purchase Price
for the shares of Common Stock to be issued under the related Purchase Contract
from the proceeds of the Pledged Treasury Securities.

        The Company shall not be obligated to issue any shares of Common Stock
in respect of a Purchase Contract or deliver any certificates therefor to the
Holder unless it shall have received payment of the aggregate purchase price for
the shares of Common Stock to be purchased thereunder in the manner herein set
forth.

        Each Purchase Contract evidenced hereby and all obligations and rights
of the Company and the Holder thereunder shall terminate if a Termination Event
shall occur. Upon the occurrence of a Termination Event, the Company shall give
written notice to the Agent and to the Holders, at their addresses as they
appear in the Treasury PIES Register. Upon and after the occurrence of a
Termination Event, the Collateral Agent shall release the Pledged Treasury
Securities (as defined in the Pledge Agreement) forming a part of each Treasury
PIES. A Treasury PIES shall thereafter represent the right to receive the
interest in the Treasury Security forming a part of such Treasury PIES, in
accordance with the terms of the Purchase Contract Agreement and the Pledge
Agreement.

        The Treasury PIES Certificates are issuable only in registered form and
only in denominations of a single Treasury PIES and any integral multiple
thereof. The transfer of any Treasury PIES Certificate will be registered and
Treasury PIES Certificates may be exchanged as provided in the Purchase Contract
Agreement. The Treasury PIES Registrar may require a Holder, among other things,
to furnish appropriate endorsements and transfer documents permitted by the
Purchase Contract Agreement. No service charge shall be required for any such
registration of transfer or exchange, but the Company and the Agent may require
payment of a sum sufficient to cover any tax or other governmental charge
payable in connection therewith. A Holder who elects to substitute Preferred
Stock for Treasury Securities, thereby recreating Corporate PIES, shall be
responsible for any fees or expenses associated therewith. Except as provided in
the Purchase Contract Agreement, for so long as the Purchase Contract underlying
a Treasury PIES remains in effect, such Treasury PIES shall not be separable
into its constituent parts, and the rights and obligations of the Holder of such
Treasury PIES in respect of the Treasury Security and the Purchase Contract
constituting such Treasury PIES may be transferred and exchanged only as a
Treasury PIES. A Holder of Treasury PIES may recreate Corporate PIES by
delivering to the Collateral Agent Preferred Stock with an aggregate liquidation

                                      B-5
<PAGE>

preference equal to the aggregate principal amount at maturity of the Pledged
Treasury Securities in exchange for the release of such Pledged Treasury
Securities in accordance with the terms of the Purchase Contract Agreement and
the Pledge Agreement. From and after such substitution, the Holder's Security
shall be referred to as an "Corporate PIES." Such substitution may cause the
equivalent aggregate principal amount of this Certificate to be increased or
decreased; provided, however, this Treasury PIES Certificate shall not represent
more than 2,000,000 Treasury PIES. All such adjustments to the equivalent
aggregate principal amount of this Treasury PIES Certificate shall be duly
recorded by placing an appropriate notation on the Schedule attached hereto.

        A Holder of a Corporate PIES may recreate a Treasury PIES by delivering
to the Collateral Agent Treasury Securities in an aggregate principal amount
equal to the aggregate liquidation preference of the Pledged Preferred Stock in
exchange for the release of such Pledged Preferred Stock in accordance with the
terms of the Purchase Contract Agreement and the Pledge Agreement. Any such
recreation of a Treasury PIES may be effected only in multiples of 20 Corporate
PIES for 20 Treasury PIES.

        The Company shall pay, on each Payment Date, the Contract Adjustment
Payments payable in respect of each Purchase Contract to the Person in whose
name the Treasury PIES Certificate evidencing such Purchase Contract is
registered at the close of business on the Record Date for such Payment Date.
Contract Adjustment Payments will be payable at the office of the Agent in The
City of New York or, at the option of the Company, by check mailed to the
address of the Person entitled thereto at such address as it appears on the
Treasury PIES Register.

        The Purchase Contracts and all obligations and rights of the Company and
the Holders thereunder, including, without limitation, the rights of the Holders
to receive and the obligation of the Company to pay Contract Adjustment
Payments, shall immediately and automatically terminate, without the necessity
of any notice or action by any Holder, the Agent or the Company, if, on or prior
to the Purchase Contract Settlement Date, a Termination Event shall have
occurred. Upon the occurrence of a Termination Event, the Company shall promptly
but in no event later than two Business Days thereafter give written notice to
the Agent, the Collateral Agent and the Holders, at their addresses as they
appear in the Treasury PIES Register. Upon the occurrence of a Termination
Event, the Collateral Agent shall release the Treasury Securities from the
Pledge in accordance with the provisions of the Pledge Agreement.

        Subject to and upon compliance with the provisions of the Purchase
Contract Agreement, at the option of the Holder thereof, Purchase Contracts
underlying Securities may be settled early (an "Early Settlement") as provided
in the Purchase Contract Agreement. In order to exercise the right to effect
Early Settlement with respect to any Purchase Contracts evidenced by this
Treasury PIES the Holder of this Treasury PIES Certificate shall deliver this
Treasury PIES Certificate to the Agent at the Corporate Trust Office duly
endorsed for transfer to the Company or in blank with the form of Election to
Settle Early set forth below duly completed and accompanied by payment in the
form of immediately available funds payable to the order of the Company in an
amount (the "Early Settlement Amount") equal to (i) the product of (A) $50 times
(B) the number of Purchase Contracts with respect to which the Holder has
elected to effect Early Settlement, plus (ii) if such delivery is made with
respect to any Purchase Contracts during

                                      B-6
<PAGE>

the period from the close of business on any Record Date for any Payment Date to
the opening of business on such Payment Date, an amount equal to the Contract
Adjustment Payments payable, if any, on such Payment Date with respect to such
Purchase Contracts. Upon Early Settlement of Purchase Contracts by a Holder of
the related Securities, the Pledged Treasury Securities underlying such
Securities shall be released from the Pledge as provided in the Pledge Agreement
and the Holder shall be entitled to receive a number of shares of Common Stock
on account of each Purchase Contract forming part of a Treasury PIES as to which
Early Settlement is effected equal to 1.11297 shares of Common Stock per
Purchase Contract (the "Early Settlement Rate"). The Early Settlement Rate shall
be adjusted in the same manner and at the same time as the Settlement Rate is
adjusted as provided in the Purchase Contract Agreement.

        Upon registration of transfer of this Treasury PIES Certificate, the
transferee shall be bound (without the necessity of any other action on the part
of such transferee, except as may be required by the Agent pursuant to the
Purchase Contract Agreement), under the terms of the Purchase Contract Agreement
and the Purchase Contracts evidenced hereby and the transferor shall be released
from the obligations under the Purchase Contracts evidenced by this Treasury
PIES Certificate. The Company covenants and agrees, and the Holder, by its
acceptance hereof, likewise covenants and agrees, to be bound by the provisions
of this paragraph.

        The Holder of this Treasury PIES Certificate, by its acceptance hereof,
authorizes the Agent to enter into and perform the related Purchase Contracts
forming part of the Treasury PIES evidenced hereby on its behalf as its
attorney-in-fact, expressly withholds any consent to the assumption (i.e.,
affirmance) of the Purchase Contracts by the Company or its trustee in the event
that the Company becomes the subject of a case under the Bankruptcy Code, agrees
to be bound by the terms and provisions thereof, covenants and agrees to perform
its obligations under such Purchase Contracts, consents to the provisions of the
Purchase Contract Agreement, authorizes the Agent to enter into and perform the
Purchase Contract Agreement and the Pledge Agreement on its behalf as its
attorney-in-fact, and consents to the Pledge of the Treasury Securities
underlying this Treasury PIES Certificate pursuant to the Pledge Agreement. The
Holder further covenants and agrees, that, to the extent and in the manner
provided in the Purchase Contract Agreement and the Pledge Agreement, but
subject to the terms thereof, payments in respect of the aggregate principal
amount of the Pledged Treasury Securities on the Purchase Contract Settlement
Date shall be paid by the Collateral Agent to the Company in satisfaction of
such Holder's obligations under such Purchase Contract and such Holder shall
acquire no right, title or interest in such payments.

        Subject to certain exceptions, the provisions of the Purchase Contract
Agreement may be amended with the consent of the Holders of a majority of the
Purchase Contracts.

        The Purchase Contracts shall for all purposes be governed by, and
construed in accordance with, the laws of the State of New York.

        The Company, the Agent and its Affiliates and any agent of the Company
or the Agent may treat the Person in whose name this Treasury PIES Certificate
is registered as the owner of the Treasury PIES evidenced hereby for the purpose
of receiving payments of interest on the Treasury Securities, receiving payments
of Contract Adjustment Payments, performance of the

                                      B-7
<PAGE>

Purchase Contracts and for all other purposes whatsoever, whether or not any
payments in respect thereof be overdue and notwithstanding any notice to the
contrary, and neither the Company, the Agent nor any such agent shall be
affected by notice to the contrary.

        The Purchase Contracts shall not, prior to the settlement thereof,
entitle the Holder to any of the rights of a holder of shares of Common Stock.

        A copy of the Purchase Contract Agreement is available for inspection at
the offices of the Agent.

        The undersigned Holder directs that a certificate for shares of Common

tenor signed by such Holders in person or by an agent duly appointed in writing;

instruments. Proof of execution of any such instrument or of a writing

Holders of the Outstanding Corporate PIES and the Outstanding Treasury PIES, as
the case may be, on such record date, and no other Holders, shall be entitled to
take the relevant action with respect to the Corporate PIES or the Treasury
PIES, as the case may be, 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
number of 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 be of no effect), and nothing in this
paragraph shall be construed to render ineffective any action taken by Holders
of the requisite number of 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
Agent in writing and to each Holder of Securities in the manner set forth in
Section 1.6.

the Agent in writing, and to each Holder of 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 Company 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.

later than the latest date, and not earlier than the earliest date, prescribed

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

action taken in reliance upon such waiver.

      In case by reason of the suspension of regular mail service or by reason
of any other cause it shall be impracticable to give such notice by mail, then

equitable right, remedy or claim under this Agreement. The Holders from time to

Section 3.1.    Amount; Form and Denominations.

      The aggregate number of Securities evidenced by Certificates
authenticated, executed on behalf of the Holders and delivered hereunder is
limited to 2,000,000 except for Certificates authenticated, executed and

Section 3.2.    Rights and Obligations Evidenced by the Certificates.

      Each Corporate PIES Certificate shall evidence the number of Corporate
PIES specified therein, with each such Corporate PIES representing the ownership
by the Holder thereof of a beneficial interest in a share of Preferred Stock,
subject to the Pledge of such share of Preferred Stock by such Holder pursuant
to the Pledge Agreement, and the rights and obligations of the Holder thereof
and the Company under one Purchase Contract. The Agent as attorney-in-fact for,
and on behalf of, the Holder of each Corporate PIES shall pledge, pursuant to
the Pledge Agreement, the share of Preferred Stock, forming a part of such
Corporate PIES, to the Collateral Agent and grant to the Collateral Agent a
security interest in the right, title and interest of such Holder in such share
of Preferred Stock for the benefit of the Company, to secure the obligation of
the Holder under each Purchase Contract to purchase the Common Stock of the
Company. Prior to the purchase of shares of Common Stock under each Purchase
Contract, such Purchase Contracts shall not entitle the Holder of a Corporate
PIES Certificate to any of the rights of a holder of shares of Common Stock,
including, without limitation, the right to vote or receive any dividends or
other payments or to consent or to receive notice as a stockholder in respect of
the

                                      17-

      Each Treasury PIES Certificate shall evidence the number of Treasury PIES
specified therein, with each such Treasury PIES representing the ownership by
the Holder thereof of a 1/20 undivided beneficial interest in a Treasury
Security with a principal amount equal to $1,000, subject to the Pledge of such
Treasury Security by such Holder pursuant to the Pledge Agreement, and the
rights and obligations of the Holder thereof and the Company under one Purchase
Contract. Prior to the purchase, if any, of shares of Common Stock under each
Purchase Contract, such Purchase Contract shall not entitle the Holder of a
Treasury PIES Certificate to any of the rights of a holder of shares of Common
Stock, including, without limitation, the right to vote or receive any dividends
or other payments or to consent or to receive notice as a stockholder in respect
of the meetings of stockholders or for the election of directors of the Company
or for any other matter, or any other rights whatsoever as a stockholder of the
Company.

Section 3.3.    Execution, Authentication, Delivery and Dating.

      Subject to the provisions of Sections 3.13 and 3.14 hereof, upon the
execution and delivery of this Agreement, and at any time and from time to time
thereafter, the Company may deliver Certificates executed by the Company to the
Agent for authentication, execution on behalf of the Holders and delivery,
together with its Issuer Order for authentication of such Certificates, and the
Agent in accordance with such Issuer Order shall authenticate, execute on behalf
of the Holders and deliver such Certificates.

      The Certificates shall be executed on behalf of the Company by its
Chairman of the Board, its President or one of its Vice Presidents. The
signature of any of these officers on the Certificates may be manual or
facsimile.

      Certificates bearing the manual or facsimile signatures of individuals who
were at any time the proper officers of the Company shall bind the Company,
notwithstanding that such individuals or any of them have ceased to hold such
offices prior to the authentication and delivery of such Certificates or did not
hold such offices at the date of such Certificates.

      No Purchase Contract evidenced by a Certificate shall be valid until such
Certificate has been executed on behalf of the Holder by the manual signature of
an authorized signatory of the Agent, as such Holder's attorney-in-fact. Such
signature by an authorized signatory of the Agent shall be conclusive evidence
that the Holder of such Certificate has entered into the Purchase Contracts
evidenced by such Certificate.

      Each Certificate shall be dated the date of its authentication.

      No Certificate shall be entitled to any benefit under this Agreement or be
valid or obligatory for any purpose unless there appears on such Certificate a
certificate of authentication substantially in the form provided for herein
executed by an authorized signatory of the Agent by

                                      18-
<PAGE>

manual signature, and such certificate upon any Certificate shall be conclusive
evidence, and the only evidence, that such Certificate has been duly
authenticated and delivered hereunder.

Section 3.4.    Temporary Certificates.

      Pending the preparation of definitive Certificates, the Company shall
provide and shall execute and deliver to the Agent, and the Agent shall
authenticate, execute on behalf of the Holders, and deliver, in lieu of such
definitive Certificates, temporary Certificates which are in substantially the
form set forth in Exhibit A or Exhibit B hereto, as the case may be, with such
letters, numbers or other marks of identification or designation and such
legends or endorsements printed, lithographed or engraved thereon as may be
required by the rules of any securities exchange on which the Corporate PIES or
Treasury PIES are listed, or as may, consistently herewith, be determined by the
officers of the Company executing such Certificates, as evidenced by their
execution of the Certificates.

      If temporary Certificates are issued, the Company will cause definitive
Certificates to be prepared without unreasonable delay. After the preparation of
definitive Certificates, the temporary Certificates shall be exchangeable for
definitive Certificates upon surrender of the temporary Certificates at the
Corporate Trust Office, at the expense of the Company and without charge to the
Holder. Upon surrender for cancellation of any one or more temporary
Certificates, the Company shall execute and deliver to the Agent, and the Agent
shall authenticate, execute on behalf of the Holder, and deliver in exchange
therefor, one or more definitive Certificates of like tenor and denominations
and evidencing a like aggregate number of Corporate PIES or Treasury PIES, as
the case may be, as the temporary Certificate or Certificates so surrendered.
Until so exchanged, the temporary Certificates shall in all respects evidence
the same benefits and the same obligations with respect to the Corporate PIES or
Treasury PIES, as the case may be, evidenced thereby as definitive Certificates.

Section 3.5.    Registration; Registration of Transfer and Exchange.

      The Agent shall keep at the Corporate Trust Office a register (the
"Corporate PIES Register") in which, subject to such reasonable regulations as
it may prescribe, the Agent shall provide for the registration of Corporate PIES
Certificates and of transfers of Corporate PIES Certificates (the Agent, in such
capacity, the "Corporate PIES Registrar") and a register (the "Treasury PIES
Register") in which, subject to such reasonable regulations as it may prescribe,
the Agent shall provide for the registration of the Treasury PIES Certificates
and transfers of Treasury PIES Certificates (the Agent, in such capacity, the
"Treasury PIES Registrar").

      Upon surrender for registration of transfer of any Certificate at the
Corporate Trust Office, the Company shall execute and deliver to the Agent, and
the Agent shall authenticate, execute on behalf of the designated transferee or
transferees, and deliver, in the name of the designated transferee or
transferees, one or more new Certificates of any authorized denominations, like
tenor, and evidencing a like aggregate number of Corporate PIES or Treasury
PIES, as the case may be.

                                      19-
<PAGE>


      At the option of the Holder, Certificates may be exchanged for other
Certificates, of any authorized denominations and evidencing a like number of
Corporate PIES or Treasury PIES, as the case may be, upon surrender of the
Certificates to be exchanged at the Corporate Trust Office. Whenever any
Certificates are so surrendered for exchange, the Company shall execute and
deliver to the Agent, and the Agent shall authenticate, execute on behalf of the
Holder, and deliver the Certificates which the Holder making the exchange is
entitled to receive.

      All Certificates issued upon any registration of transfer or exchange of a
Certificate shall evidence the ownership of the same aggregate number of
Corporate PIES or Treasury PIES, as the case may be, and be entitled to the same
benefits and subject to the same obligations, under this Agreement as the
Corporate PIES or Treasury PIES, as the case may be, evidenced by the
Certificate surrendered upon such registration of transfer or exchange.

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

      No service charge shall be made for any registration of transfer or
exchange of a Certificate, but the Company and the Agent may require payment
from the Holder of a sum sufficient to cover any tax or other governmental
charge that may be imposed in connection with any registration of transfer or
exchange of Certificates, other than any exchanges pursuant to Sections 3.6,
3.10 and 8.5 not involving any transfer.

      Notwithstanding the foregoing, the Company shall not be obligated to
execute and deliver to the Agent, and the Agent shall not be obligated to
authenticate, execute on behalf of the Holder and deliver any Certificate in
exchange for any other Certificate presented or surrendered for registration of
transfer or for exchange on or after the Business Day immediately preceding the
earlier of the Purchase Contract Settlement Date or the Termination Date. In
lieu of delivery of a new Certificate, upon satisfaction of the applicable
conditions specified above in this Section and receipt of appropriate
registration or transfer instructions from such Holder, the Agent shall (i) if
the Purchase Contract Settlement Date has occurred, deliver the shares of Common
Stock issuable in respect of the Purchase Contracts forming a part of the
Securities evidenced by such other Certificate or (ii) if a Termination Event
shall have occurred prior to the Purchase Contract Settlement Date, transfer the
Preferred Stocks or the Treasury Securities, as the case may be, evidenced
thereby, in each case subject to the applicable conditions and in accordance
with the applicable provisions of Article Five hereof.

Section 3.6.    Book-Entry Interests.

      The Certificates, on original issuance, will be issued in the form of one
or more fully registered Global Certificates, to be delivered to the Depositary
by, or on behalf of, the Company. Such Global Certificate shall initially be
registered on the books and records of the Company in the name of Cede & Co.,
the nominee of the Depositary, and no Beneficial Owner will receive a definitive
Certificate representing such Beneficial Owner's interest in such Global
Certificate, except as provided in Section 3.9. The Agent shall enter into an
agreement with the Depositary if

                                      20-

<PAGE>

so requested by the Company. Unless and until definitive, fully registered
Certificates have been issued to Beneficial Owners pursuant to Section 3.9:

      (a)  the provisions of this Section 3.6 shall be in full force and
effect;

      (b)  the Company and the Agent shall be entitled to deal with the Clearing
Agency for all purposes of this Agreement (including the payment of Contract
Adjustment Payments, if any, and receiving approvals, votes or consents
hereunder and for purposes of Section 3.11 hereof) as the Holder of the
Securities and the sole holder of the Global Certificate(s) and shall have no
obligation to the Beneficial Owners;

      (c)  to the extent that the provisions of this Section 3.6 conflict
with any other provisions of this Agreement, the provisions of this Section 3.6
shall control; and

      (d)  the rights of the Beneficial Owners shall be exercised only
through the Clearing Agency and shall be limited to those established by law and
agreements between such Beneficial Owners and the Clearing Agency and/or the
Clearing Agency Participants.

Section 3.7.    Notices to Holders.

      Whenever a notice or other communication to the Holders is required to be
given under this Agreement, the Company or the Company's agent shall give such
notices and communications to the Holders and, with respect to any Securities
registered in the name of a Clearing Agency or the nominee of a Clearing Agency,
the Company or the Company's agent shall, except as set forth herein, have no
obligations to the Beneficial Owners.

Section 3.8.    Appointment of Successor Clearing Agency.

      If any Clearing Agency elects to discontinue its services as securities
depositary with respect to the Securities, the Company may, in its sole
discretion, appoint a successor Clearing Agency with respect to the Securities.

Section 3.9.    Definitive Certificates.

      If (i) a Clearing Agency elects to discontinue its services as securities
depositary with respect to the Securities and a successor Clearing Agency is not
appointed within 90 days after such discontinuance pursuant to Section 3.8 or
(ii) there shall have occurred and be continuing a default by the Company in
respect of its obligations under one or more Purchase Contracts, then upon
surrender of the Global Certificates representing the Securities by the Clearing
Agency, accompanied by registration instructions, the Company shall cause
definitive Certificates to be delivered to Beneficial Owners in accordance with
the instructions of the Clearing Agency. The Company shall not be liable for any
delay in delivery of such instructions and may conclusively rely on and shall be
protected in relying on, such instructions.

Section 3.10.   Mutilated, Destroyed, Lost and Stolen Certificates.

                                      21-
<PAGE>


      If any mutilated Certificate is surrendered to the Agent, the Company
shall execute and deliver to the Agent, and the Agent shall authenticate,
execute on behalf of the Holder, and deliver in exchange therefor, a new
Certificate, evidencing the same number of Corporate PIES or Treasury PIES, as
the case may be, and bearing a Certificate number not contemporaneously
outstanding.

      If there shall be delivered to the Company and the Agent (i) evidence to
their satisfaction of the destruction, loss or theft of any Certificate, and
(ii) such security or indemnity as may be required by them to hold each of them
and any agent of any of them harmless, then, in the absence of notice to the
Company or the Agent that such Certificate has been acquired by a bona fide
purchaser, the Company shall execute and deliver to the Agent, and the Agent
shall authenticate, execute on behalf of the Holder, and deliver to the Holder,
in lieu of any such destroyed, lost or stolen Certificate, a new Certificate,
evidencing the same number of Corporate PIES or Treasury PIES, as the case may
be, and bearing a Certificate number not contemporaneously outstanding.

      Notwithstanding the foregoing, the Company shall not be obligated to
execute and deliver to the Agent, and the Agent shall not be obligated to
authenticate, execute on behalf of the Holder, and deliver to the Holder, a
Certificate on or after the Business Day immediately preceding the earlier of
the Purchase Contract Settlement Date or the Termination Date. In lieu of
delivery of a new Certificate, upon satisfaction of the applicable conditions
specified above in this Section and receipt of appropriate registration or
transfer instructions from such Holder, the Agent shall (i) if the Purchase
Contract Settlement Date has occurred, deliver the shares of Common Stock
issuable in respect of the Purchase Contracts forming a part of the Securities
evidenced by such Certificate, or (ii) if a Termination Event shall have
occurred prior to the Purchase Contract Settlement Date, transfer the Preferred
Stock or the Treasury Securities, as the case may be, evidenced thereby, in each
case subject to the applicable conditions and in accordance with the applicable
provisions of Article Five hereof.

      Upon the issuance of any new Certificate under this Section, the Company
and the Agent may require the payment by the Holder 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 Agent) connected
therewith.

      Every new Certificate issued pursuant to this Section in lieu of any
destroyed, lost or stolen Certificate shall constitute an original additional
contractual obligation of the Company and of the Holder in respect of the
Security evidenced thereby, whether or not the destroyed, lost or stolen
Certificate (and the Securities evidenced thereby) shall be at any time
enforceable by anyone, and shall be entitled to all the benefits and be subject
to all the obligations of this Agreement equally and proportionately with any
and all other Certificates delivered hereunder.

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

Section 3.11.   Persons Deemed Owners.

                                      22-
<PAGE>


      Prior to due presentment of a Certificate for registration of transfer,
the Company and the Agent, and any agent of the Company or the Agent, may treat
the Person in whose name such Certificate is registered as the owner of the
Corporate PIES or Treasury PIES evidenced thereby, for the purpose of receiving
dividend payments on the Preferred Stock receiving payments of Contract
Adjustment Payments, performance of the Purchase Contracts and for all other
purposes whatsoever, whether or not any dividend payments on the Preferred Stock
or the Contract Adjustment Payments payable in respect of the Purchase Contracts
constituting a part of the Corporate PIES or Treasury PIES evidenced thereby
shall be overdue and notwithstanding any notice to the contrary, and neither the
Company nor the Agent, nor any agent of the Company or the Agent, shall be
affected by notice to the contrary.

      Notwithstanding the foregoing, with respect to any Global Certificate,
nothing herein shall prevent the Company, the Agent or any agent of the Company
or the Agent, from giving effect to any written certification, proxy or other
authorization furnished by any Clearing Agency (or its nominee), as a Holder,
with respect to such Global Certificate or impair, as between such Clearing
Agency and owners of beneficial interests in such Global Certificate, the
operation of customary practices governing the exercise of rights of such
Clearing Agency (or its nominee) as Holder of such Global Certificate.

Section 3.12.   Cancellation.

      All Certificates surrendered for delivery of shares of Common Stock on or
after the Purchase Contract Settlement Date, upon the transfer of Preferred
Stock or Treasury Securities, as the case may be, after the occurrence of a
Termination Event or pursuant to an Early Settlement, or upon the registration
of a transfer or exchange of a Security, or a Collateral Substitution or the
re-establishment of a Corporate PIES shall, if surrendered to any Person other
than the Agent, be delivered to the Agent and, if not already cancelled, shall
be promptly cancelled by it. The Company may at any time deliver to the Agent
for cancellation any Certificates previously authenticated, executed and
delivered hereunder which the Company may have acquired in any manner
whatsoever, and all Certificates so delivered shall, upon Issuer Order, be
promptly cancelled by the Agent. No Certificates shall be authenticated,
executed on behalf of the Holder and delivered in lieu of or in exchange for any
Certificates cancelled as provided in this Section, except as expressly
permitted by this Agreement. All cancelled Certificates held by the Agent shall
be destroyed by the Agent unless otherwise directed by Issuer Order.

      If the Company or any Affiliate of the Company shall acquire any
Certificate, such acquisition shall not operate as a cancellation of such
Certificate unless and until such Certificate is delivered to the Agent
cancelled or for cancellation.

Section 3.13.   Substitution of Securities.

      A Holder may separate the shares of Preferred Stock from the related
Purchase Contracts in respect of a Corporate PIES by substituting, for such
shares of Preferred Stock Treasury Securities in an aggregate principal amount
equal to the aggregate liquidation preference of such shares of Preferred stock
(a "Collateral Substitution"), at any time from and after the date of this

                                      23-
<PAGE>

Agreement and on or prior to the seventh Business Day immediately preceding the
Purchase Contract Settlement Date by (a) depositing with the Securities
Intermediary Treasury Securities or securities entitlements thereto having an
aggregate principal amount equal to the aggregate liquidation preference of the
shares of Preferred stock comprising part of such Corporate PIES and (b)
transferring the related Corporate PIES to the Agent accompanied by a notice to
the Agent, substantially in the form of Exhibit C hereto, stating that the
Holder has transferred the relevant amount of Treasury Securities to the
Securities Intermediary and requesting that the Agent instruct the Collateral
Agent to release the share of Preferred Stock underlying such Corporate PIES,
whereupon the Agent shall promptly give such instruction to the Collateral
Agent, substantially in the form of Exhibit A to the Pledge Agreement. Upon
receipt of the Treasury Securities described in clause (a) above and the
instruction described in clause (b) above, in accordance with the terms of the
Pledge Agreement, the Collateral Agent will cause the Securities Intermediary to
release from the Pledge to the Agent, on behalf of the Holder, shares of
Preferred Stock having a corresponding aggregate liquidation preference free and
clear of the Company's security interest therein, and upon receipt thereof the
Agent shall promptly:

               (i)      cancel the related Corporate PIES;

              (ii)      transfer the share of Preferred Stock to the Holder; and

             (iii)      authenticate, execute on behalf of such Holder and
      deliver a Treasury PIES Certificate executed by the Company in accordance
      with Section 3.3 evidencing the same number of Purchase Contracts as were
      evidenced by the cancelled Corporate PIES.

      Holders who elect to separate the shares of Preferred Stock from the
related Purchase Contract and to substitute Treasury Securities for such shares
of Preferred Stock shall be responsible for any fees or expenses payable to the
Collateral Agent for its services as Collateral Agent in respect of the
substitution, and the Company shall not be responsible for any such fees or
expenses.

      Holders may make Collateral Substitutions only in integral multiples of 20
Corporate PIES if Treasury Securities are being substituted for shares of
Preferred Stock.

      In the event a Holder making a Collateral Substitution pursuant to this
Section 3.13 fails to effect a book-entry transfer of the Corporate PIES or
fails to deliver a Corporate PIES Certificate(s) to the Agent after depositing
Treasury Securities with the Collateral Agent, the shares of Preferred Stock ,
constituting a part of such Corporate PIES, and any dividends on such shares of
Preferred Stock, shall be held in the name of the Agent or its nominee in trust
for the benefit of such Holder, until such Corporate PIES is so transferred or
the Corporate PIES Certificate is so delivered, as the case may be, or, with
respect to a Corporate PIES Certificate, such Holder provides evidence
satisfactory to the Company and the Agent that such Corporate PIES Certificate
has been destroyed, lost or stolen, together with any indemnity that may be
required by the Agent and the Company.

      Except as described in this Section 3.13, for so long as the Purchase
Contract underlying a Corporate PIES remains in effect, such Corporate PIES
shall not be separable into its constituent parts, and the rights and
obligations of the Holder in respect of the shares of Preferred Stock and the
Purchase Contract comprising such Corporate PIES may be acquired, and may be
transferred and exchanged, only as a Corporate PIES.

Section 3.14.   Reestablishment of Corporate PIES.

      A Holder of a Treasury PIES may recreate Corporate PIES at any time on or
prior to the seventh Business Day immediately preceding the Purchase Contract
Settlement Date by (a) depositing with the Securities Intermediary shares of
Preferred stock or security entitlements thereto having an aggregate liquidation
preference equal to the aggregate principal amount at maturity of the Treasury
Securities comprising part of the Treasury PIES and (b) transferring the related
Treasury PIES to the Agent accompanied by a notice to the Agent, substantially
in the form of Exhibit C hereto, stating that the Holder has transferred the
relevant amount of shares of Preferred Stock to the Securities Intermediary and
requesting that the Agent instruct the Collateral Agent to release the Treasury
Securities underlying such Treasury PIES, whereupon the Agent shall promptly
give such instruction to the Collateral Agent, substantially in the form of
Exhibit C to the Pledge Agreement. Upon receipt of the shares of Preferred Stock
described in clause (a) above and the instruction described in clause (b) above,
in accordance with the terms of the Pledge Agreement, the Collateral Agent will
cause the Securities Intermediary to effect the release of the Treasury
Securities having a corresponding aggregate principal amount at maturity from
the Pledge to the Agent free and clear of the Company's security interest
therein, and upon receipt thereof the Agent shall promptly:

               (i)      cancel the related Treasury PIES;

              (ii)      transfer the Treasury Securities to the Holder; and

             (iii)      authenticate, execute on behalf of such Holder and
      deliver a Corporate PIES Certificate executed by the Company in accordance
      with Section 3.3 evidencing the same number of Purchase Contracts as were
      evidenced by the cancelled Treasury PIES.

      Holders who elect to recreate Corporate PIES shall be responsible for any
fees or expenses payable to the Collateral Agent for its services as Collateral
Agent in respect of the substitution, and the Company shall not be responsible
for any such fees or expenses.

      Holders of Treasury PIES may reestablish Corporate PIES in integral
multiples of 20 Treasury PIES for 20 Corporate PIES.

      Except as provided in this Section 3.14, for so long as the Purchase
Contract underlying a Treasury PIES remains in effect, such Treasury PIES shall
not be separable into its constituent parts and the rights and obligations of
the Holder of such Treasury PIES in respect of the 1/20 of a Treasury Security
and the Purchase Contract comprising such Treasury PIES may be acquired, and may
be transferred and exchanged, only as a Treasury PIES.

Section 3.15.   Transfer of Collateral upon Occurrence of Termination Event.

      Upon notice to the Agent of the occurrence of a Termination Event and the
transfer to the Agent of the shares of Preferred Stock or the Treasury
Securities, as the case may be, underlying the Corporate PIES and the Treasury
PIES pursuant to the terms of the Pledge Agreement, the Agent shall request
transfer instructions with respect to such Shares or Treasury Securities, as the
case may be, from each Holder by written request, substantially in the form of
Exhibit D hereto, mailed to such Holder at its address as it appears in the
Corporate PIES Register or the Treasury PIES Register, as the case may be. Upon
book-entry transfer of the Corporate PIES or Treasury PIES or delivery of a
Corporate PIES Certificate or Treasury PIES Certificate to the Agent with such
transfer instructions, the Agent shall transfer the shares of Preferred Stock or
Treasury Securities, as the case may be, underlying such Corporate PIES or
Treasury PIES, as the case may be, to such Holder by book-entry transfer, or
other appropriate procedures, in accordance with such instructions. In the event
a Holder of Corporate PIES or Treasury PIES fails to effect such transfer or
delivery, the shares of Preferred Stock or Treasury Securities, as the case may
be, underlying such Corporate PIES or Treasury PIES, as the case may be, and any
dividends or interest thereon, shall be held in the name of the Agent or its
nominee in trust for the benefit of such Holder, until the earlier of (a)
transfer of such Corporate PIES or Treasury PIES or surrender of the Corporate
PIES Certificate or Treasury PIES Certificate or such Holder provides
satisfactory evidence that such Corporate PIES Certificate or Treasury PIES
Certificate has been destroyed, lost or stolen, together with any indemnity that
may be required by the Agent and the Company and (b) the expiration of the time
period specified in the abandoned property laws of the relevant State.

Section 3.16.   No Consent to Assumption.

      Each Holder of a Security, by acceptance thereof, shall be deemed
expressly to have withheld any consent to the assumption under Section 365 of
the Bankruptcy Code or otherwise, of the Purchase Contract by the Company or its
trustee, receiver, liquidator or a person or entity performing similar functions
in the event that the Company becomes the debtor under the Bankruptcy Code or
subject to other similar state or federal law providing for reorganization or
liquidation.

                          The Shares of Preferred Stock

Section 4.1.     Payment of Dividends; Rights to Dividends Preserved;
                 Dividend Rate Reset.

      Dividends on any share of Preferred Stock which are paid on any Payment
Date shall, subject to receipt thereof by the Agent from the Securities
Intermediary as provided by the terms of the Pledge Agreement together with the
Contract Adjustment Payments, be paid to the Person in whose name the Corporate
PIES Certificate (or one or more Predecessor Corporate PIES

                                      26-
<PAGE>

Certificates) of which such Share is a part is registered at the close of
business on the Record Date for such Payment Date.

      Each Corporate PIES Certificate evidencing shares of Preferred Stock
delivered under this Agreement upon registration of transfer of or in exchange
for or in lieu of any other Corporate PIES Certificate shall carry the rights to
accrued and unpaid dividends, and to accrue dividends, which were carried by the
shares of Preferred Stock underlying such other Corporate PIES Certificate.

      In the case of any Corporate PIES with respect to which Cash Settlement of
the underlying Purchase Contract is effected on or prior to the fifth Business
Day immediately preceding the Purchase Contract Settlement Date pursuant to
prior notice, or with respect to which Early Settlement of the underlying
Purchase Contract is effected on an Early Settlement Date, or with respect to
which a Collateral Substitution is effected, in each case on a date that is
after any Record Date and on or prior to the next succeeding Payment Date,
dividends on the shares of Preferred Stock underlying such Corporate PIES
otherwise payable on such Payment Date shall be payable on such Payment Date
notwithstanding such Cash Settlement or Early Settlement or Collateral
Substitution, and such dividends shall, subject to receipt thereof by the Agent,
be payable to the Person in whose name the Corporate PIES Certificate (or one or
more Predecessor Corporate PIES Certificates) was registered at the close of
business on the Record Date. Except as otherwise expressly provided in the
immediately preceding sentence, in the case of any Corporate PIES with respect
to which Cash Settlement or Early Settlement of the underlying Purchase Contract
is effected on or prior to the fifth Business Day immediately preceding the
Purchase Contract Settlement Date or an Early Settlement Date, as the case may
be, or with respect to which a Collateral Substitution has been effected,
dividends on the related shares of Preferred Stock that would otherwise be
payable after the Purchase Contract Settlement Date or Early Settlement Date
shall not be payable hereunder to the Holder of such Corporate PIES; provided,
however, that to the extent that such Holder continues to hold the separated
shares of Preferred Stock that formerly comprised a part of such Holder's
Corporate PIES, such Holder shall be entitled to receive the dividends on such
separated shares of Preferred Stock pursuant to their terms.

      The applicable dividend rate borne by the shares of Preferred Stock on and
after the Purchase Contract Settlement Date shall be established pursuant to the
Remarketing on the third Business Day immediately preceding the Purchase
Contract Settlement Date to equal to the Reset Rate (such Reset Rate to be in
effect on and after the Purchase Contract Settlement Date).

Section 4.2.     Notice and Voting.

      Under the terms of the Pledge Agreement, the Agent will be entitled to
exercise the voting and any other consensual rights pertaining to the Pledged
Preferred Stock, as the case may be, but only to the extent instructed in
writing by the Holders as described below. Upon receipt of notice of any meeting
called by the Company or Holders of Shares at which holders of shares of
Preferred stock are entitled to vote or upon any solicitation of consents,
waivers or proxies of holders of shares of Preferred stock, the Agent shall, as
soon as practicable thereafter, mail to the Holders of Corporate PIES a notice
(a) containing such information as is contained in the notice or solicitation,
(b) stating that each Holder on the record date set by the Agent therefor
(which, to

                                      27-
<PAGE>

the extent possible, shall be the same date as the record date for determining
the holders of shares of Preferred Stock, as the case may be, entitled to vote)
shall be entitled to instruct the Agent as to the exercise of the voting rights
pertaining to such shares of Preferred Stock underlying their Corporate PIES and
(c) stating the manner in which such instructions may be given. Upon the written
request of the Holders of Corporate PIES on such record date received by the
Agent at least six days prior to such meeting, the Agent shall endeavor insofar
as practicable to vote or cause to be voted, in accordance with the instructions
set forth in such requests, the maximum liquidation preference of shares of
Preferred Stock as to which any particular voting instructions are received. In
the absence of specific instructions from the Holder of a Corporate PIES, the
Agent shall abstain from voting the shares of Preferred Stock underlying such
Corporate PIES. The Company hereby agrees, if applicable, to solicit Holders of
Corporate PIES to timely instruct the Agent in order to enable the Agent to vote
such shares of Preferred Stock.

                                    ARTICLE V

                             The Purchase Contracts

Section 5.1.      Purchase of Shares of Common Stock.

      Each Purchase Contract shall, unless an Early Settlement has occurred in
accordance with Section 5.9 hereof, obligate the Holder of the related Security
to purchase, and the Company to sell, on the Purchase Contract Settlement Date
at a price equal to the Stated Amount (the "Purchase Price"), a number of newly
issued shares of Common Stock equal to the Settlement Rate unless, on or prior
to the Purchase Contract Settlement Date, there shall have occurred a
Termination Event with respect to the Security of which such Purchase Contract
is a part. The "Settlement Rate" is equal to (a) if the Applicable Market Value
(as defined below) is equal to or greater than $44.9250 (the "Threshold
Appreciation Price"), 1.11297 shares of Common Stock per Purchase Contract, (b)
if the Applicable Market Value is less than the Threshold Appreciation Price,
but is greater than $37.4375, the number of shares of Common Stock equal to the
Stated Amount divided by the Applicable Market Value and (c) if the Applicable
Market Value is less than or equal to $37.4375, 1.33556 shares of Common Stock
per Purchase Contract, in each case subject to adjustment as provided in Section
5.6 (and in each case rounded upward or downward to the nearest 1/10,000th of a
share). As provided in Section 5.10, no fractional shares of Common Stock will
be issued upon settlement of Purchase Contracts.

      The Company shall determine the Applicable market Value and the Agent may
conclusively rely on such determination.


      The "Applicable Market Value" means the average of the Closing Price per
share of Common Stock on each of the 20 Trading Days ending on the third Trading
Day immediately preceding the Purchase Contract Settlement Date. The "Closing
Price" of the Common Stock on any date of determination means (i) the closing
sale price (or, if no closing price is reported, the last reported sale price)
of the Common Stock on the Nasdaq National Market on such date, (ii) if the
Common Stock is not listed for trading on the Nasdaq National Market on any such
date, the

                                      28-
<PAGE>

closing sale price as reported in the composite transactions for the principal
United States securities exchange on which the Common Stock is so listed, (iii)
if the Common Stock is not so reported, the last quoted bid price for the Common
Stock in the over-the-counter market as reported by the National Quotation
Bureau or similar organization or (iv) if such bid price is not available, the
average of the mid-point of the last bid and ask prices of the Common Stock on
such date from at least three nationally recognized independent investment
banking firms retained for this purpose by the Company. A "Trading Day" means a
day on which the Common Stock (A) is not suspended from trading on any national
or regional securities exchange or association or over-the-counter market at the
close of business and (B) has traded at least once on the national or regional
securities exchange or association or over-the-counter market that is the
primary market for the trading of the Common Stock.

      Each Holder of a Corporate PIES or a Treasury PIES, by its acceptance
thereof, irrevocably authorizes the Agent to enter into and perform the related
Purchase Contract on its behalf as its attorney-in-fact (including the execution
of Certificates on behalf of such Holder), agrees to be bound by the terms and
provisions thereof, covenants and agrees to perform its obligations under such
Purchase Contracts, and consents to the provisions hereof, irrevocably
authorizes the Agent as its attorney-in-fact to enter into and perform this
Agreement and the Pledge Agreement on its behalf as its attorney-in-fact, and
consents to and agrees to be bound by the Pledge of the shares of Preferred
Stock or the Treasury Securities pursuant to the Pledge Agreement; provided that
upon a Termination Event, the rights of the Holder of such Security under the
Purchase Contract may be enforced without regard to any other rights or
obligations. Each Holder of a Corporate PIES or a Treasury PIES, by its
acceptance thereof, further covenants and agrees, that to the extent and in the
manner provided in Section 5.4 and the Pledge Agreement, but subject to the
terms thereof, Proceeds from the remarketing of the shares of Preferred Stock or
the Proceeds of the Treasury Securities on the Purchase Contract Settlement Date
shall be paid by the Collateral Agent to the Company in satisfaction of such
Holder's obligations under such Purchase Contract and such Holder shall acquire
no right, title or interest in such payments.

      Upon registration of transfer of a Certificate, the transferee shall be
bound (without the necessity of any other action on the part of such transferee)
by the terms of this Agreement, the Purchase Contracts underlying such
Certificate and the Pledge Agreement and the transferor shall be released from
the obligations under this Agreement, the Purchase Contracts underlying the
Certificates so transferred and the Pledge Agreement. The Company covenants and
agrees, and each Holder of a Certificate, by its acceptance thereof, likewise
covenants and agrees, to be bound by the provisions of this paragraph.

Section 5.2.      Contract Adjustment Payments.

      The Company shall pay, on each Payment Date, the Contract Adjustment
Payments payable in respect of each Purchase Contract to the Person in whose
name a Certificate (or one or more Predecessor Certificates) is registered at
the close of business on the Record Date next preceding such Payment Date. The
Contract Adjustment Payments together with the dividends on any Share pursuant
to section 4.1 will be payable at the office of the Agent maintained for that
purpose or, at the option of the Company, by check mailed to the address of the
Person entitled

                                      29-
<PAGE>

thereto at such Person's address as it appears on the Corporate PIES Register or
Treasury PIES Register.

      Upon the occurrence of a Termination Event, the Company's obligation to
pay Contract Adjustment Payments (including any accrued Contract Adjustment
Payments) shall cease.

      Each Certificate delivered under this Agreement upon registration of
transfer of or in exchange for or in lieu of (including as a result of a
Collateral Substitution or the re-establishment of a Corporate PIES) any other
Certificate shall carry the rights to Contract Adjustment Payments accrued and
unpaid, and to accrue Contract Adjustment Payments, which were carried by the
Purchase Contracts underlying such other Certificates.

      Subject to Section 5.9, in the case of any Security with respect to which
Early Settlement of the underlying Purchase Contract is effected on an Early
Settlement Date that is after any Record Date and on or prior to the next
succeeding Payment Date, Contract Adjustment Payments, if any, otherwise payable
on such Payment Date shall be payable on such Payment Date notwithstanding such
Early Settlement, and such Contract Adjustment Payments shall be paid to the
Person in whose name the Certificate evidencing such Security (or one or more
Predecessor Certificates) is registered at the close of business on such Record
Date. Except as otherwise expressly provided in the immediately preceding
sentence, in the case of any Security with respect to which Early Settlement of
the underlying Purchase Contract is effected on an Early Settlement Date,
Contract Adjustment Payments that would otherwise be payable after the Early
Settlement Date with respect to such Purchase Contract shall not be payable.

Section 5.3.      [Intentionally omitted].

Section 5.4.      Payment of Purchase Price.

      (a) (i) Unless a Holder settles the underlying Purchase Contract through
the early delivery of cash to the Purchase Contract Agent in the manner
described in Section 5.9, each Holder of a Corporate PIES who intends to pay in
cash to satisfy such Holder's obligation under the Purchase Contract shall
notify the Agent by use of a notice in substantially the form of Exhibit E
hereto of its intention to pay in cash (the "Cash Settlement") the Purchase
Price for the shares of Common Stock to be purchased pursuant to a Purchase
Contract. Such notice shall be given prior to 5:00 p.m., New York City time, on
the seventh Business Day immediately preceding the Purchase Contract Settlement
Date. Prior to 11:00 a.m., New York City time, on the next succeeding Business
Day, the Agent shall notify the Collateral Agent of the receipt of such notices
from Holders intending to make a Cash Settlement.

      (ii) A Holder of a Corporate PIES who has so notified the Agent of its
intention to make a Cash Settlement shall pay the Purchase Price to the
Securities Intermediary for deposit in the Collateral Account prior to 11:00
a.m., New York City time, on the fifth Business Day immediately preceding the
Purchase Contract Settlement Date in lawful money of the United States by
certified or cashiers' check or wire transfer, in each case in immediately
available funds payable to or upon the order of the Securities Intermediary. Any
cash received by the Collateral Agent shall be invested promptly by the
Securities Intermediary in Permitted Investments and paid to the Company on the
Purchase Contract Settlement Date in settlement of

                                      30-
<PAGE>

the Purchase Contract in accordance with the terms of this Agreement and the
Pledge Agreement. Any funds received by the Securities Intermediary in respect
of the investment earnings from the investment in such Permitted Investments
shall be distributed to the Agent when received for payment to the Holder of the
related Corporate PIES on the Purchase Contract Settlement Date.

     (iii) If a Holder of a Corporate PIES fails to notify the Agent of its
intention to make a Cash Settlement in accordance with paragraph (a)(i) above,
or does notify the Agent as provided in paragraph (a)(i) above of its intention
to pay the Purchase Price in cash, but fails to make such payment as required by
paragraph (a)(ii) above, such Holder shall be deemed to have consented to the
disposition of the Pledged shares of Preferred Stock pursuant to the remarketing
as described in paragraph (b) below.

      (iv) Not later than 15 calendar days nor more than 30 calendar days prior
to the third Business Day immediately preceding the Purchase Contract Settlement
Date, the Company shall request DTC (or any successor Clearing Agency), to
notify the Beneficial Owners or Clearing Agency Participants holding Corporate
PIES or Treasury PIES of the procedures to be followed by Holders of Corporate
PIES who intend to effect the settlement of their obligations under the Purchase
Contracts underlying such Corporate PIES with separate cash on or prior to the
fifth Business Day prior to the Purchase Contract Settlement Date.

       (v) Promptly after 11:00 a.m., New York City time, on the fifth Business
Day preceding the Purchase Contract Settlement Date, the Agent, based on notices
received by the Agent pursuant to Section 5.4(a)(i) hereof and notice from the
Securities Intermediary regarding cash received by it prior to such time, shall
notify the Collateral Agent of the aggregate liquidation preference of shares of
Preferred Stock to be tendered for purchase in the Remarketing in a notice
substantially in the form of Exhibit F hereto.

      (b) In order to dispose of the shares of Preferred Stock, Corporate PIES
Holders who have not notified the Agent of their intention to effect a Cash
Settlement as provided in paragraph (a)(i) above, or who have so notified the
Agent but fail to make such payment as required by paragraph (a)(ii) above, the
Company shall engage Lehman Brothers Inc. (the "Remarketing Agent") pursuant to
the Remarketing Agreement to sell such shares of Preferred Stock. In order to
facilitate the remarketing, the Agent, based on the notices specified in Section
5.4(a)(v), shall notify the Remarketing Agent, promptly after 11:00 a.m., New
York City time, on the fifth Business Day immediately preceding the Purchase
Contract Settlement Date, of the aggregate principal liquidation preference of
shares of Preferred Stock that are a component of Corporate PIES to be
remarketed. Concurrently, the Collateral Agent, pursuant to the terms of the
Pledge Agreement, shall cause such shares of Preferred Stock to be presented to
the Remarketing Agent for remarketing. Upon receipt of such notice from the
Agent and such shares of Preferred Stock, the Remarketing Agent shall, on the
third Business Day immediately preceding the Purchase Contract Settlement Date,
use commercially reasonable efforts to remarket such Shares on such date at a
price of 100.50% of the aggregate liquidation preference of such shares of
Preferred Stock. The proceeds equal to 100% of the aggregate liquidation
preference of the remarketed shares of Preferred Stock shall automatically be
applied by the Collateral Agent, in accordance with the Pledge Agreement, to
satisfy in full such Corporate PIES Holders' obligations to pay the Purchase
Price for the Common Stock under the related

                                      31-
<PAGE>

Purchase Contracts on the Purchase Contract Settlement Date. The proceeds equal
to .50% of the aggregate liquidation preference of the remarketed shares of
Preferred Stock shall automatically be applied, in accordance with the Pledge
Agreement, to pay the remarketing fee of the Remarketing Agent. Corporate PIES
Holders whose shares of Preferred Stock are so remarketed shall not be
responsible for the payment of any remarketing fee in connection therewith. If,
in spite of using their reasonable efforts, the Remarketing Agent cannot
remarket the related shares of Preferred Stock of such Holders of Corporate PIES
at a price of 100.50% of the aggregate liquidation preference of such shares of
Preferred Stock, the remarketing shall be deemed to have failed (a "Failed
Remarketing") and in accordance with the terms of the Pledge Agreement the
Collateral Agent, for the benefit of the Company, shall be entitled to exercise
its rights as a secured party with respect to such shares of Preferred Stock,
including those actions specified in paragraph (c) below; provided that if upon
a Failed Remarketing the Collateral Agent exercises such rights for the benefit
of the Company with respect to such shares of Preferred Stock, any accrued and
unpaid dividends on such Shares shall become payable by the Company to the Agent
for payment to the Beneficial Owner of the Corporate PIES to which such shares
of Preferred Stock relate. The Company shall cause a notice of such Failed
Remarketing to be published no later than the Business Day immediately preceding
the Purchase Contract Settlement Date in a daily newspaper in the English
language of general circulation in the City of New York, which is expected to be
The Wall Street Journal.

      (c) With respect to any shares of Preferred Stock which are subject to a
Failed Remarketing, the Collateral Agent for the benefit of the Company reserves
all of its rights as a secured party with respect thereto and, subject to
applicable law and paragraph (g) below, may, among other things, (i) retain the
shares of Preferred Stock in full satisfaction of the Holders' obligations under
the Purchase Contracts or (ii) sell the shares of Preferred Stock in one or more
public or private sales.

      (d) (i) Unless a Holder of Treasury PIES settles the underlying Purchase
Contract through the early delivery of cash to the Purchase Contract Agent in
the manner described in Section 5.9, each Holder of a Treasury PIES who intends
to pay in cash shall notify the Agent by use of a notice in substantially the
form of Exhibit E hereto of its intention to pay in cash the Purchase Price for
the shares of Common Stock to be purchased pursuant to a Purchase Contract. Such
notice shall be given on or prior to 5:00 p.m., New York City time, on the
second Business Day immediately preceding the Purchase Contract Settlement Date.

      (ii) A Holder of a Treasury PIES who has so notified the Agent of its
intention to make a Cash Settlement in accordance with paragraph (d)(i) above
shall pay the Purchase Price to the Securities Intermediary for deposit in the
Collateral Account prior to 11:00 a.m., New York City time, on the Business Day
immediately preceding the Purchase Contract Settlement Date in lawful money of
the United States by certified or cashiers' check or wire transfer, in each case
in immediately available funds payable to or upon the order of the Securities
Intermediary. Any cash received by the Collateral Agent shall be invested
promptly by the Securities Intermediary in Permitted Investments and paid to the
Company on the Purchase Contract Settlement Date in settlement of the Purchase
Contract in accordance with the terms of this Agreement and the Pledge
Agreement. Any funds received by the Securities Intermediary in

                                      32-

<PAGE>

respect of the investment earnings from the investment in such Permitted
Investments shall be distributed to the Agent when received for payment to the
Holder.

     (iii) If a Holder of a Treasury PIES fails to notify the Agent of its
intention to make a Cash Settlement in accordance with paragraph (d)(i) above,
or does notify the Agent as provided in paragraph (d)(i) above of its intention
to pay the Purchase Price in cash, but fails to make such payment as required by
paragraph (d)(ii) above, then upon the maturity of the Pledged Treasury
Securities held by the Securities Intermediary on the Business Day immediately
prior to the Purchase Contract Settlement Date, the principal amount of the
Treasury Securities received by the Securities Intermediary shall be invested
promptly in Permitted Investments. On the Purchase Contract Settlement Date an
amount equal to the Purchase Price shall be remitted to the Company as payment
thereof without receiving any instructions from the Holder. In the event the sum
of the proceeds from the related Pledged Treasury Securities and the investment
earnings earned from such investments is in excess of the aggregate Purchase
Price of the Purchase Contracts being settled thereby, the Collateral Agent
shall cause the Securities Intermediary to distribute such excess to the Agent
for the benefit of the Holder of the related Treasury PIES when received.

      (e) Any distribution to Holders of excess funds and interest described
above shall be payable at the office of the Agent maintained for that purpose
or, at the option of the Holder, by check mailed to the address of the Person
entitled thereto at such address as it appears on the Register.

      (f) Upon Cash Settlement of any Purchase Contract, (i) the Collateral
Agent will in accordance with the terms of the Pledge Agreement cause the
Pledged Preferred Stock or the Pledged Treasury Securities, as the case may be,
underlying the relevant Security to be released from the Pledge free and clear
of any security interest of the Company and transferred to the Agent for
delivery to the Holder thereof or its designee as soon as practicable and (ii)
subject to the receipt thereof, the Agent shall, by book-entry transfer, or
other appropriate procedures, in accordance with written instructions provided
by the Holder thereof, transfer such shares of Preferred Stock or such Treasury
Securities, as the case may be (or, if no such instructions are given to the
Agent by the Holder, the Agent shall hold such shares of Preferred Stock or such
Treasury Securities, as the case may be, and any dividends or interest thereon,
as the case may be, in the name of the Agent or its nominee in trust for the
benefit of such Holder until the expiration of the time period specified in the
abandoned property laws of the relevant State).

      (g) The obligations of the Holders to pay the Purchase Price are
non-recourse obligations and, except to the extent paid by Early Settlement or
Cash Settlement, are payable solely out of the proceeds of any Collateral
pledged to secure the obligations of the Holders and in no event will Holders be
liable for any deficiency between the proceeds of the disposition of Collateral
and the Purchase Price.

Section 5.5.      Issuance of Shares of Common Stock.

      Unless a Termination Event or an Early Settlement shall have occurred,
subject to Section 5.6(b), the Company shall issue and deposit with the Agent,
for the benefit of the Holders of the

                                      33-
<PAGE>

Outstanding Securities, one or more certificates representing the newly issued
shares of Common Stock registered in the name of the Agent (or its nominee) as
custodian for the Holders (such certificates for shares of Common Stock,
together with any dividends or distributions for which a record date and payment
date for such dividend or distribution has occurred after the Purchase Contract
Settlement Date, being hereinafter referred to as the "Purchase Contract
Settlement Fund") to which the Holders are entitled hereunder. Subject to the
foregoing, upon surrender of a Certificate to the Agent on or after the Purchase
Contract Settlement Date, together with settlement instructions thereon duly
completed and executed, the Holder of such Certificate shall be entitled to
receive in exchange therefor a certificate representing that number of whole
shares of Common Stock which such Holder is entitled to receive pursuant to the
provisions of this Article Five (after taking into account all Securities then
held by such Holder), together with cash in lieu of fractional shares as
provided in Section 5.10 and any dividends or distributions with respect to such
Shares constituting part of the Purchase Contract Settlement Fund, but without
any interest thereon, and the Certificate so surrendered shall forthwith be
cancelled. Such shares shall be registered in the name of the Holder or the
Holder's designee as specified in the settlement instructions provided by the
Holder to the Agent. If any shares of Common Stock issued in respect of a
Purchase Contract are to be registered to a Person other than the Person in
whose name the Certificate evidencing such Purchase Contract is registered, no
such registration shall be made unless the Person requesting such registration
has paid any transfer and other taxes required by reason of such registration in
a name other than that of the registered Holder of the Certificate evidencing
such Purchase Contract or has established to the satisfaction of the Company
that such tax either has been paid or is not payable.

Section 5.6.      Adjustment of Settlement Rate.

      (a)   Adjustments for Dividends, Distributions, Stock Splits, Etc.

            (1) In case the Company shall pay or make a dividend or other
distribution on the Common Stock in Common Stock, the Settlement Rate in effect
at the opening of business on the day following the date fixed for the
determination of stockholders entitled to receive such dividend or other
distribution shall be increased by dividing such Settlement Rate by a fraction
of which the numerator shall be the number of shares of Common Stock outstanding
at the close of business on the date fixed for such determination and the
denominator shall be the sum of such number of shares and the total number of
shares constituting such dividend or other distribution, such increase to become
effective immediately after the opening of business on the day following the
date fixed for such determination. For the purposes of this paragraph (1), the
number of shares of Common Stock at any time outstanding shall not include
shares held in the treasury of the Company but shall include any shares issuable
in respect of any scrip certificates issued in lieu of fractions of shares of
Common Stock. The Company will not pay any dividend or make any distribution on
shares of Common Stock held in the treasury of the Company.

            (2) In case the Company shall issue rights, options or warrants to
all holders of its Common Stock (not being available on an equivalent basis to
Holders of the Securities upon settlement of the Purchase Contracts underlying
such Securities) entitling them, for a period expiring within 45 days after the
record date for the determination of stockholders entitled to receive such
rights, options or warrants, to subscribe for or purchase shares of Common Stock
at

                                      34-
<PAGE>

a price per share less than the Current Market Price per share of the Common
Stock on the date fixed for the determination of stockholders entitled to
receive such rights, options or warrants (other than pursuant to a dividend
reinvestment plan), the Settlement Rate in effect at the opening of business on
the day following the date fixed for such determination shall be increased by
dividing such Settlement Rate by a fraction of which the numerator shall be the
number of shares of Common Stock outstanding at the close of business on the
date fixed for such determination plus the number of shares of Common Stock
which the aggregate of the offering price of the total number of shares of
Common Stock so offered for subscription or purchase would purchase at such
Current Market Price and the denominator shall be the number of shares of Common
Stock outstanding at the close of business on the date fixed for such
determination plus the number of shares of Common Stock so offered for
subscription or purchase, such increase to become effective immediately after
the opening of business on the day following the date fixed for such
determination. For the purposes of this paragraph (2), the number of shares of
Common Stock at any time outstanding shall not include shares held in the
treasury of the Company but shall include any shares issuable in respect of any
scrip certificates issued in lieu of fractions of shares of Common Stock. The
Company shall not issue any such rights, options or warrants in respect of
shares of Common Stock held in the treasury of the Company.

            (3) In case outstanding shares of Common Stock shall be subdivided
or split into a greater number of shares of Common Stock, the Settlement Rate in
effect at the opening of business on the day following the day upon which such
subdivision or split becomes effective shall be proportionately increased, and,
conversely, in case outstanding shares of Common Stock shall each be combined
into a smaller number of shares of Common Stock, the Settlement Rate in effect
at the opening of business on the day following the day upon which such
combination becomes effective shall be proportionately reduced, such increase or
reduction, as the case may be, to become effective immediately after the opening
of business on the day following the day upon which such subdivision, split or
combination becomes effective.

            (4) In case the Company shall, by dividend or otherwise, distribute
to all holders of its Common Stock evidences of its indebtedness or assets
(including securities, but excluding any rights or warrants referred to in
paragraph (2) of this Section, any dividend or distribution paid exclusively in
cash and any dividend or distribution referred to in paragraph (1) of this
Section), the Settlement Rate shall be adjusted so that the same shall equal the
rate determined by dividing the Settlement Rate in effect immediately prior to
the close of business on the date fixed for the determination of stockholders
entitled to receive such distribution by a fraction of which the numerator shall
be the Current Market Price per share of the Common Stock on the date fixed for
such determination less the then fair market value (as determined by the Board
of Directors, whose determination shall be conclusive and described in a Board
Resolution) of the portion of the assets or evidences of indebtedness so
distributed applicable to one share of Common Stock and the denominator shall be
such Current Market Price per share of the Common Stock, such adjustment to
become effective immediately prior to the opening of business on the day
following the date fixed for the determination of stockholders entitled to
receive such distribution. In any case in which this paragraph (4) is
applicable, paragraph (2) of this Section shall not be applicable.

                                      35-

            (5) In case the Company shall, by dividend or otherwise, distribute
to all holders of its Common Stock (I) cash (excluding any cash that is
distributed in a Reorganization Event to which Section 5.6(b) applies or as part
of a distribution referred to in paragraph (4) of this Section) in an aggregate
amount that, combined together with the aggregate amount of any other
distributions to all holders of its Common Stock made exclusively in cash (other
than in connection with a Reorganization Event) within the 12 months preceding
the date of payment of such distribution and in respect of which no adjustment
pursuant to this paragraph (5) or paragraph (6) of this Section has been made
and (II) the aggregate of any cash plus the fair market value (as determined by
the Board of Directors, whose determination shall be conclusive and described in
a Board Resolution) of consideration payable in respect of any tender or
exchange offer by the Company or any of its subsidiaries for all or any portion
of the Common Stock concluded within the 12 months preceding the date of payment
of the distribution described in Clause (I) above and in respect of which no
adjustment pursuant to this paragraph (5) or paragraph (4) or paragraph (6) of
this Section has been made, exceeds 15% of the product of the Current Market
Price per share of the Common Stock on the date for the determination of holders
of shares of Common Stock entitled to receive such distribution times the number
of shares of Common Stock outstanding on such date, then, and in each such case,
immediately after the close of business on such date for determination, the
Settlement Rate shall be increased so that the same shall equal the rate
determined by dividing the Settlement Rate in effect immediately prior to the
close of business on the date fixed for determination of the stockholders
entitled to receive such distribution by a fraction (i) the numerator of which
shall be equal to the Current Market Price per share of the Common Stock on the
date fixed for such determination less an amount equal to the quotient of (x)
the combined amount distributed or payable in the transactions described in
clauses (I) and (II) above divided by (y) the number of shares of Common Stock
outstanding on such date for determination and (ii) the denominator of which
shall be equal to the Current Market Price per share of the Common Stock on such
date for determination.

            (6) In case a tender or exchange offer made by the Company or any
subsidiary of the Company for all or any portion of the Common Stock shall
expire and such tender or exchange offer (as amended upon the expiration
thereof) shall require the payment to stockholders (based on the acceptance (up
to any maximum specified in the terms of the tender or exchange offer) of
Purchased Shares) of (I) an aggregate consideration having a fair market value
(as determined by the Board of Directors, whose determination shall be
conclusive and described in a Board Resolution) that combined together with the
aggregate of the cash plus the fair market value (as determined by the Board of
Directors, whose determination shall be conclusive and described in a Board
Resolution), as of the expiration of such tender or exchange offer, of
consideration payable in respect of any other tender or exchange offer, by the
Company or any subsidiary of the Company for all or any portion of the Common
Stock expiring within the 12 months preceding the expiration of such tender or
exchange offer and in respect of which no adjustment pursuant to paragraph (5)
of this Section or this paragraph (6) has been made and (II) the aggregate
amount of any distributions to all holders of the Company's Common Stock made
exclusively in cash within the 12 months preceding the expiration of such tender
or exchange offer and in respect of which no adjustment pursuant to paragraph
(5) of this Section or this paragraph (6) has been made, exceeds 15% of the
product of the Current Market Price per share of the Common Stock as of the last
time (the "Expiration Time") tenders could have been

                                      36-
<PAGE>

made pursuant to such tender or exchange offer (as it may be amended) times the
number of shares of Common Stock outstanding (including any tendered shares) on
the Expiration Time, then, and in each such case, immediately prior to the
opening of business on the day after the date of the Expiration Time, the
Settlement Rate shall be adjusted so that the same shall equal the rate
determined by dividing the Settlement Rate immediately prior to the close of
business on the date of the Expiration Time by a fraction (i) the numerator of
which shall be equal to (A) the product of (1) the Current Market Price per
share of the Common Stock on the date of the Expiration Time and (2) the number
of shares of Common Stock outstanding (including any tendered shares) on the
Expiration Time less (B) the amount of cash plus the fair market value
(determined as aforesaid) of the aggregate consideration payable to stockholders
based on the transactions described in clauses (I) and (II) above (assuming in
the case of clause (I) the acceptance, up to any maximum specified in the terms
of the tender or exchange offer, of Purchased Shares), and (ii) the denominator
of which shall be equal to the product of (A) the Current Market Price per share
of the Common Stock as of the Expiration Time and (B) the number of shares of
Common Stock outstanding (including any tendered shares) as of the Expiration
Time less the number of all shares validly tendered and not withdrawn as of the
Expiration Time (the shares deemed so accepted, up to any such maximum, being
referred to as the "Purchased Stock").

            (7) The reclassification of Common Stock into securities including
securities other than Common Stock (other than any reclassification upon a
Reorganization Event to which Section 5.6(b) applies) shall be deemed to involve
(a) a distribution of such securities other than Common Stock to all holders of
Common Stock (and the effective date of such reclassification shall be deemed to
be "the date fixed for the determination of stockholders entitled to receive
such distribution" and the "date fixed for such determination" within the
meaning of paragraph (4) of this Section), and (b) a subdivision, split or
combination, as the case may be, of the number of shares of Common Stock
outstanding immediately prior to such reclassification into the number of shares
of Common Stock outstanding immediately thereafter (and the effective date of
such reclassification shall be deemed to be "the day upon which such subdivision
or split becomes effective" or "the day upon which such combination becomes
effective", as the case may be, and "the day upon which such subdivision, split
or combination becomes effective" within the meaning of paragraph (3) of this
Section).

            (8) The "Current Market Price" per share of Common Stock on any day
means the average of the daily Closing Prices for the five consecutive Trading
Days selected by the Company commencing not more than 30 Trading Days before,
and ending not later than, the earlier of the day in question and the day before
the "ex date" with respect to the issuance or distribution requiring such
computation. For purposes of this paragraph, the term "ex date", when used with
respect to any issuance or distribution, shall mean the first date on which the
Common Stock trades regular way on such exchange or in such market without the
right to receive such issuance or distribution.

            (9) All adjustments to the Settlement Rate shall be calculated to
the nearest 1/10,000th of a share of Common Stock (or if there is not a nearest
1/10,000th of a share, to the next lower 1/10,000th of a share). No adjustment
in the Settlement Rate shall be required unless such adjustment would require an
increase or decrease of at least one percent thereof; provided,

                                      37-
<PAGE>

however, that any adjustments which by reason of this subparagraph are not
required to be made shall be carried forward and taken into account in any
subsequent adjustment. If an adjustment is made to the Settlement Rate pursuant
to paragraph (1), (2), (3), (4), (5), (6), (7) or (10) of this Section 5.6(a),
an adjustment shall also be made to the Applicable Market Value solely to
determine which of clauses (a), (b) or (c) of the definition of Settlement Rate
in Section 5.1 will apply on the Purchase Contract Settlement Date. Such
adjustment shall be made by multiplying the Applicable Market Value by a
fraction of which the numerator shall be the Settlement Rate immediately after
such adjustment pursuant to paragraph (1), (2), (3), (4), (5), (6), (7) or (10)
of this Section 5.6(a) and the denominator shall be the Settlement Rate
immediately before such adjustment; provided, however, that if such adjustment
to the Settlement Rate is required to be made pursuant to the occurrence of any
of the events contemplated by paragraph (1), (2), (3), (4), (5), (7) or (10) of
this Section 5.6(a) during the period taken into consideration for determining
the Applicable Market Value, appropriate and customary adjustments shall be made
to the Settlement Rate.

            (10) The Company may make such increases in the Settlement Rate, in
addition to those required by this Section, as it considers to be advisable in
order to avoid or diminish any income tax to any holders of shares of Common
Stock resulting from any dividend or distribution of stock or issuance of rights
or warrants to purchase or subscribe for stock or from any event treated as such
for income tax purposes or for any other reason.

      (b)   Adjustment for Consolidation, Merger or Other Reorganization
Event.

            In the event of (i) any consolidation or merger of the Company with
or into another Person (other than a merger or consolidation in which the
Company is the continuing corporation and in which the Common Stock outstanding
immediately prior to the merger or consolidation is not exchanged for cash,
securities or other property of the Company or another corporation), (ii) any
sale, transfer, lease or conveyance to another Person of the property of the
Company as an entirety or substantially as an entirety, (iii) any statutory
exchange of securities of the Company with another Person (other than in
connection with a merger or acquisition) or (iv) any liquidation, dissolution or
winding up of the Company other than as a result of or after the occurrence of a
Termination Event (any such event, a "Reorganization Event"), the Settlement
Rate will be adjusted to provide that each Holder of Securities will receive on
the Purchase Contract Settlement Date with respect to each Purchase Contract
forming a part thereof, the kind and amount of securities, cash and other
property receivable upon such Reorganization Event (without any interest
thereon, and without any right to dividends or distribution thereon which have a
record date that is prior to the Purchase Contract Settlement Date) by a Holder
of the number of shares of Common Stock issuable on account of each Purchase
Contract if the Purchase Contract Settlement Date had occurred immediately prior
to such Reorganization Event assuming such Holder of Common Stock is not a
Person with which the Company consolidated or into which the Company merged or
which merged into the Company or to which such sale or transfer was made, as the
case may be (any such Person, a "Constituent Person"), or an Affiliate of a
Constituent Person to the extent such Reorganization Event provides for
different treatment of Common Stock held by Affiliates of the Company and
non-affiliates and such Holder failed to exercise his rights of election, if
any, as to the kind or amount of securities, cash and other property receivable
upon such Reorganization Event (provided that if the kind or amount of

                                      38-
<PAGE>

securities, cash and other property receivable upon such Reorganization Event is
not the same for each share of Common Stock held immediately prior to such
Reorganization Event by other than a Constituent Person or an Affiliate thereof
and in respect of which such rights of election shall not have been exercised
("non-electing share"), then for the purpose of this Section the kind and amount
of securities, cash and other property receivable upon such Reorganization Event
by each non-electing share shall be deemed to be the kind and amount so
receivable per share by a plurality of the non-electing shares). In the event of
such a Reorganization Event, the Person formed by such consolidation, merger or
exchange or the Person which acquires the assets of the Company or, in the event
of a liquidation or dissolution of the Company, the Company or a liquidating
trust created in connection therewith, shall execute and deliver to the Agent an
agreement supplemental hereto providing that the Holders of each Outstanding
Security shall have the rights provided by this Section 5.6(b). Such
supplemental agreement shall provide for adjustments which, for events
subsequent to the effective date of such supplemental agreement, shall be as
nearly equivalent as may be practicable to the adjustments provided for in this
Section. The above provisions of this Section shall similarly apply to
successive Reorganization Events.

Section 5.7.      Notice of Adjustments and Certain Other Events.

      (a) Whenever the Settlement Rate is adjusted as herein provided, the
Company shall:

            (i) forthwith compute the adjusted Settlement Rate in accordance
      with Section 5.6 and prepare and transmit to the Agent an Officers'
      Certificate setting forth the Settlement Rate, the method of calculation
      thereof in reasonable detail, and the facts requiring such adjustment and
      upon which such adjustment is based; and

            (ii) within 10 Business Days following the occurrence of an event
      that requires an adjustment to the Settlement Rate pursuant to Section 5.6
      (or if the Company is not aware of such occurrence, as soon as practicable
      after becoming so aware), provide a written notice to the Holders of the
      Securities of the occurrence of such event and a statement in reasonable
      detail setting forth the method by which the adjustment to the Settlement
      Rate was determined and setting forth the adjusted Settlement Rate.

      (b) The Agent shall not at any time be under any duty or responsibility to
any Holder of Securities to determine whether any facts exist which may require
any adjustment of the Settlement Rate, or with respect to the nature or extent
or calculation of any such adjustment when made, or with respect to the method
employed in making the same. The Agent shall not be accountable with respect to
the validity or value (or the kind or amount) of any shares of Common Stock, or
of any securities or property, which may at the time be issued or delivered with
respect to any Purchase Contract; and the Agent makes no representation with
respect thereto. The Agent shall not be responsible for any failure of the
Company to issue, transfer or deliver any shares of Common Stock pursuant to a
Purchase Contract or to comply with any of the duties, responsibilities or
covenants of the Company contained in this Article.

Section 5.8.      Termination Event; Notice.

                                      39-
<PAGE>


      The Purchase Contracts and all obligations and rights of the Company and
the Holders thereunder, including, without limitation, the rights of the Holders
to receive and the obligation of the Company to pay any Contract Adjustment
Payments, if the Company shall have such obligation, and the rights and
obligations of Holders to purchase Common Stock, shall immediately and
automatically terminate, without the necessity of any notice or action by any
Holder, the Agent or the Company, if, on or prior to the Purchase Contract
Settlement Date, a Termination Event shall have occurred. Upon and after the
occurrence of a Termination Event, the Securities shall thereafter represent the
right to receive the shares of Preferred Stock forming a part of such Securities
in the case of Corporate PIES, or Treasury Securities in the case of Treasury
PIES, in accordance with the provisions of Section 5.4 of the Pledge Agreement.
Upon the occurrence of a Termination Event, the Company shall promptly but in no
event later than two Business Days thereafter give written notice to the Agent,
the Collateral Agent and the Holders, at their addresses as they appear in the
Register.

Section 5.9.      Early Settlement.

      (a) Subject to and upon compliance with the provisions of this Section
5.9, at the option of the Holder thereof, Purchase Contracts underlying
Securities may be settled early (an "Early Settlement") in the case of Corporate
PIES on or prior to the seventh Business Day immediately preceding the Purchase
Contract Settlement Date and in the case of Treasury PIES on or prior to the
second Business Day immediately preceding the Purchase Contract Settlement Date,
in each case, as provided herein. In order to exercise the right to effect Early
Settlement with respect to any Purchase Contracts, the Holder of the Certificate
evidencing Securities shall deliver such Certificate to the Agent at the
Corporate Trust Office duly endorsed for transfer to the Company or in blank
with the form of Election to Settle Early on the reverse thereof duly completed
and accompanied by payment (payable to the Company in immediately available
funds) in an amount (the "Early Settlement Amount") equal to (i) the product of
(A) the Stated Amount times (B) the number of Purchase Contracts with respect to
which the Holder has elected to effect Early Settlement plus (ii) if such
delivery is made with respect to any Purchase Contracts during the period from
the close of business on any Record Date next preceding any Payment Date to the
opening of business on such Payment Date, an amount equal to the sum of (x) the
Contract Adjustment Payments payable on such Payment Date with respect to such
Purchase Contracts plus (y) in the case of a Corporate PIES Certificate, the
distributions on the related shares of Preferred Stock payable on such Payment
Date. Except as provided in the immediately preceding sentence and subject to
the last paragraph of Section 5.2, no payment or adjustment shall be made upon
Early Settlement of any Purchase Contract on account of any Contract Adjustment
Payments accrued on such Purchase Contract or on account of any dividends on the
Common Stock issued upon such Early Settlement. If the foregoing requirements
are first satisfied with respect to Purchase Contracts underlying any Securities
at or prior to 5:00 p.m., New York City time, on a Business Day, such day shall
be the "Early Settlement Date" with respect to such Securities and if such
requirements are first satisfied after 5:00 p.m., New York City time, on a
Business Day or on a day that is not a Business Day, the "Early Settlement Date"
with respect to such Securities shall be the next succeeding Business Day.

                                      40-
<PAGE>

      (b) Upon Early Settlement of Purchase Contracts by a Holder of the related
Securities, the Company shall issue, and the Holder shall be entitled to
receive, 1.11297 shares of Common Stock on account of each Purchase Contract as
to which Early Settlement is effected (the "Early Settlement Rate"). The Early
Settlement Rate shall be adjusted in the same manner and at the same time as the
Settlement Rate is adjusted.

      (c) No later than the third Business Day after the applicable Early
Settlement Date, the Company shall cause (i) the shares of Common Stock issuable
upon Early Settlement of Purchase Contracts to be issued and delivered, together
with payment in lieu of any fraction of a share, as provided in Section 5.10,
and (ii) the related shares of Preferred Stock, in the case of Corporate PIES,
or the related Treasury Securities, in the case of Treasury PIES, to be released
from the Pledge by the Collateral Agent and transferred, in each case, to the
Agent for delivery to the Holder thereof or its designee.

      (d) Upon Early Settlement of any Purchase Contracts, and subject to
receipt of shares of Common Stock from the Company and the shares of Preferred
Stock or Treasury Securities, as the case may be, from the Securities
Intermediary, as applicable, the Agent shall, in accordance with the
instructions provided by the Holder thereof on the applicable form of Election
to Settle Early on the reverse of the Certificate evidencing the related
Securities, (i) transfer to the Holder the shares of Preferred Stock or Treasury
Securities, as the case may be, forming a part of such Securities, and (ii)
deliver to the Holder a certificate or certificates for the full number of
shares of Common Stock issuable upon such Early Settlement, together with
payment in lieu of any fraction of a share, as provided in Section 5.10.

      (e) In the event that Early Settlement is effected with respect to
Purchase Contracts underlying less than all the Securities evidenced by a
Certificate, upon such Early Settlement the Company shall execute and the Agent
shall authenticate, countersign and deliver to the Holder thereof, at the
expense of the Company, a Certificate evidencing the Securities as to which
Early Settlement was not effected.

Section 5.10.     No Fractional Shares.

      No fractional shares or scrip representing fractional shares of Common
Stock shall be issued or delivered upon settlement on the Purchase Contract
Settlement Date or upon Early Settlement of any Purchase Contracts. If
Certificates evidencing more than one Purchase Contract shall be surrendered for
settlement at one time by the same Holder, the number of full shares of Common
Stock which shall be delivered upon settlement shall be computed on the basis of
the aggregate number of Purchase Contracts evidenced by the Certificates so
surrendered. Instead of any fractional share of Common Stock which would
otherwise be deliverable upon settlement of any Purchase Contracts on the
Purchase Contract Settlement Date or upon Early Settlement, the Company, through
the Agent, shall make a cash payment in respect of such fractional interest in
an amount equal to the value of such fractional shares times the Applicable
Market Value. The Company shall provide the Agent from time to time with
sufficient funds to permit the Agent to make all cash payments required by this
Section 5.10 in a timely manner.

Section 5.11.     Charges and Taxes.

                                      41-
<PAGE>


      The Company will pay all stock transfer and similar taxes attributable to
the initial issuance and delivery of the shares of Common Stock pursuant to the
Purchase Contracts; provided, however, that the Company shall not be required to
pay any such tax or taxes which may be payable in respect of any exchange of or
substitution for a Certificate evidencing a Security or any issuance of a share
of Common Stock in a name other than that of the registered Holder of a
Certificate surrendered in respect of the Securities evidenced thereby, other
than in the name of the Agent, as custodian for such Holder, and the Company
shall not be required to issue or deliver such share certificates or
Certificates unless or until the Person or Persons requesting the transfer or
issuance thereof shall have paid to the Company the amount of such tax or shall
have established to the satisfaction of the Company that such tax has been paid.

                                   ARTICLE VI

                                    Remedies

Section 6.1.     Unconditional Right of Holders to Receive Contract
            Adjustment Payments and to Purchase Common Stock.

      In the event that Contract Adjustment Payments shall constitute a
component of Corporate PIES or Treasury PIES, the Holder of any Corporate PIES
or Treasury PIES shall have the right, which is absolute and unconditional
(subject to the payment by a holder of Contract Adjustment Payments pursuant to
Section 5.9(a)), to receive payment of each installment of the Contract
Adjustment Payments with respect to the Purchase Contract constituting a part of
such Security on the respective Payment Date for such Security and to purchase
Common Stock pursuant to such Purchase Contract and, in each such case, to
institute suit for the enforcement of any such payment and right to purchase
Common Stock, and such rights shall not be impaired without the consent of such
Holder.

Section 6.2.     Restoration of Rights and Remedies.

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

Section 6.3.     Rights and Remedies Cumulative.

      Except as otherwise provided with respect to the replacement or payment of
mutilated, destroyed, lost or stolen Certificates in the last paragraph of
Section 3.10, no right or remedy herein conferred upon or reserved 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

                                      42-
<PAGE>

equity or otherwise. The assertion or employment of any right or remedy
hereunder, or otherwise, shall not prevent the concurrent assertion or
employment of any other appropriate right or remedy.

Section 6.4.     Delay or Omission Not Waiver.

      No delay or omission of any Holder to exercise any right or remedy upon a
default shall impair any such right or remedy or constitute a waiver of any such
right. Every right and remedy given by this Article or by law to the Holders may
be exercised from time to time, and as often as may be deemed expedient, by such
Holders.

Section 6.5.     Undertaking for Costs.

      All parties to this Agreement agree, and each Holder of Corporate PIES or
Treasury PIES, by its acceptance of such Corporate PIES or Treasury PIES, 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 Agreement, or in any
suit against the Agent for any action taken, suffered or omitted by it as Agent,
the filing by any party litigant in such suit of an undertaking to pay the costs
of such suit, and that such court may in its discretion assess reasonable costs,
including reasonable attorneys' fees, against any party litigant in such suit,
having due regard to the merits and good faith of the claims or defenses made by
such party litigant; provided that the provisions of this Section shall not
apply to any suit instituted by the Company, to any suit instituted by the
Agent, to any suit instituted by any Holder, or group of Holders, holding in the
aggregate more than 10% of the Outstanding Securities, or to any suit instituted
by any Holder for the enforcement of dividends payable on any shares of
Preferred Stock or Contract Adjustment Payments, if any, on any Purchase
Contract on or after the respective Payment Date therefor in respect of any
Security held by such Holder, or for enforcement of the right to purchase shares
of Common Stock under the Purchase Contracts constituting part of any Security
held by such Holder.

Section 6.6.     Waiver of 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 stay or extension law wherever enacted,
now or at any time hereafter in force, which may affect the covenants or the
performance of this Agreement; 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 Agent or the Holders, but will suffer and permit the
execution of every such power as though no such law had been enacted.

<PAGE>

      (a) (1) The Agent undertakes to perform, with respect to the Securities,
      such duties and only such duties as are specifically set forth in this
      Agreement and the Pledge Agreement, and no implied covenants or
      obligations shall be read into this Agreement or the Pledge Agreement
      against the Agent; and

            (2) in the absence of bad faith or gross negligence on its part, the
      Agent may, with respect to the Securities, conclusively rely on as valid
      and genuine any signature, document or certificate and 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
      Agent and conforming to the requirements of this Agreement or the Pledge
      Agreement, as applicable, but in the case of any certificates or opinions
      which by any provision hereof are specifically required to be furnished to
      the Agent, the Agent shall be only under a duty to examine the same to
      determine whether or not they conform to the requirements of this
      Agreement or the Pledge Agreement, as applicable.

      (b) No provision of this Agreement or the Pledge Agreement shall be
construed to relieve the Agent from liability for its own negligent action, its
own negligent failure to act, or its own wilful misconduct, except that

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

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

            (3) no provision of this Agreement or the Pledge Agreement shall
      require the Agent 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 adequate indemnity is
      not provided to it.

      (c) Whether or not therein expressly so provided, every provision of this
Agreement and the Pledge Agreement relating to the conduct or affecting the
liability of or affording protection to the Agent shall be subject to the
provisions of this Section.

      (d) The Agent is authorized to execute and deliver the Pledge Agreement in
its capacity as Agent.

Section 7.2.    Notice of Default.

      Within 30 days after the occurrence of any default by the Company
hereunder of which a Responsible Officer of the Agent has actual knowledge, the
Agent shall transmit by mail to the Company and the Holders of Securities, as
their names and addresses appear in the Register, notice of such default
hereunder, unless such default shall have been cured or waived.

      The Company covenants that it will not merge or consolidate with any other

may be made in the Certificates evidencing Securities thereafter to be issued as
may be appropriate.

Section 9.3.     Opinion of Counsel Given to Agent.

      The Agent, subject to Sections 7.1 and 7.3, shall receive an Opinion of

Purchase Contract with the Company. All capitalized terms used herein which are
defined in the Purchase Contract Agreement (as defined on the reverse hereof)
have the meaning set forth therein.

to secure the obligations of the Holder under the Purchase Contract comprising a
portion of such Corporate PIES.

      The Pledge Agreement provides that all payments of the liquidation
preference with respect to any of the Pledged Preferred Stock or cash dividends

(ii) in the case of Proceeds from the Remarketing with respect to any of the
Pledged Preferred stock or security entitlements thereto, to the Company on the
Purchase Contract Settlement Date (as described herein) in accordance with the
terms of the Pledge Agreement, in full satisfaction of the respective
obligations of the Holders of the Corporate PIES of which such Pledged Preferred
Stock is a part under the Purchase Contracts forming a part of such Corporate
PIES. Dividends on any Preferred Stock forming part of a Corporate PIES
evidenced hereby, which is payable quarterly in arrears on February 16, May 16,
August 16 and November 16 of each year, commencing November 16, 1999 (a "Payment
Date"), shall, subject to receipt thereof by the Agent from the Securities
Intermediary, be paid to the Person in whose name this Corporate PIES
Certificate (or a Predecessor Corporate PIES Certificate) is registered at the
close of business on the Record Date for such Payment Date.

      Each Purchase Contract evidenced hereby obligates the Holder of this
Corporate PIES Certificate to purchase, and the Company to sell, on August 16,
2002 (the "Purchase Contract Settlement Date"), at a price equal to $50 in cash
(the "Stated Amount"), a number of Common Shares, par value $0.01 ("Common
Stock"), of the Company, equal to the Settlement Rate, unless on or prior to the
Purchase Contract Settlement Date there shall have occurred a Termination Event
or an Early Settlement with respect to the Corporate PIES of which such Purchase
Contract is a part, all as provided in the Purchase Contract Agreement and more
fully described on the reverse hereof. The purchase price (the "Purchase Price")
for the shares of Common Stock purchased pursuant to each Purchase Contract
evidenced hereby, if not paid earlier, shall be paid on the Purchase Contract
Settlement Date by separate cash or by application of payment received, pursuant
to the Remarketing, in respect of the liquidation preference with respect to any
Pledged Preferred Stock pledged to secure the obligations under such Purchase
Contract of the Holder of the Corporate PIES of which such Purchase Contract is
a part.

      The Company shall pay, on each Payment Date, in respect of each Purchase
Contract forming part of a Corporate PIES evidenced hereby an amount (the
"Contract Adjustment Payments") equal to (a) if a Reset Transaction has not
occurred, 0.75% per annum of the Stated Amount or (b) following the occurrence
of a Reset Transaction, the Adjusted Contract Adjustment Payment Rate related to
such Reset Transaction until any such succeeding Reset

Transaction shall occur (computed on the basis of (i) for any full quarterly
period, a 360-day year of twelve 30-day months and (ii) for any period shorter

the actual number of days elapsed per 30-day period). Such Contract Adjustment
Payments shall be payable to the Person in whose name this Corporate PIES
Certificate (or a Predecessor Corporate PIES Certificate) is registered at the
close of business on the Record Date for such Payment Date.

payable at the office of the Agent in The City of New York or, at the option of
the Company, by check mailed to the address of the Person entitled thereto as
such address appears on the Corporate PIES Register.

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

                 (FORM OF REVERSE OF CORPORATE PIES CERTIFICATE)

     Each Purchase Contract evidenced hereby is governed by a Purchase Contract
Agreement, dated as of August 10, 1999 (as may be supplemented from time to
time, the "Purchase Contract Agreement"), between the Company and The First
National Bank of Chicago, as Purchase Contract Agent (including its successors
hereunder, the "Agent"), to which Purchase Contract Agreement and supplemental
agreements thereto reference is hereby made for a description of the respective
rights, limitations of rights, obligations, duties and immunities thereunder of
the Agent, the Company, and the Holders and of the terms upon which the
Corporate PIES Certificates are, and are to be, executed and delivered.

     Each Purchase Contract evidenced hereby obligates the Holder of this
Corporate PIES Certificate to purchase, and the Company to sell, on the Purchase
Contract Settlement Date at a price equal to the Stated Amount (the "Purchase
Price"), a number of shares of Common Stock of the Company equal to the
Settlement Rate, unless, on or prior to the Purchase Contract Settlement Date,
there shall have occurred a Termination Event with respect to the Security of
which such Purchase Contract is a part or an Early Settlement shall have
occurred. The "Settlement Rate" is equal to (a) if the Applicable Market Value
(as defined below) is equal to or greater than $44.9250 (the "Threshold
Appreciation Price"), 1.11297 shares of Common Stock per Purchase Contract, (b)
if the Applicable Market Value is less than the Threshold Appreciation Price but
is greater than $37.4375 the number of shares of Common Stock per Purchase
Contract equal to the Stated Amount divided by the Applicable Market Value and
(c) if the Applicable Market Amount is less than or equal to $37.4375, 1.33556
shares of Common Stock per Purchase Contract, in each case subject to adjustment
as provided in the Purchase Contract Agreement. No fractional shares of Common
Stock will be issued upon settlement of Purchase Contracts, as provided in the
Purchase Contract Agreement.

     Each Purchase Contract evidenced hereby, which is settled either through
Early Settlement or Cash Settlement, shall obligate the Holder of the related
Corporate PIES to purchase at the Purchase Price, and the Company to sell, a
number of newly issued shares of Common Stock equal to the Early Settlement Rate
or the Settlement Rate, as applicable.

     The "Applicable Market Value" means the average of the Closing Price per
share of Common Stock on each of the 20 Trading Days ending on the third Trading
Day immediately preceding the Purchase Contract Settlement Date. The "Closing
Price" of the Common Stock on any date of determination means (i) the closing
sale price (or, if no closing price is reported, the last reported sale price)
of the Common Stock on the Nasdaq National Market on such date, (ii) if the
Common Stock is not listed for trading on the Nasdaq National Market on any such
date, the closing sale price as reported in the composite transactions for the
principal United States securities exchange on which the Common Stock is so
listed, (iii) if the Common Stock is not so reported, the last quoted bid price
for the Common Stock in the over-the-counter market as

                                      A-5
<PAGE>

reported by the National Quotation Bureau or similar organization or (iv) if
such bid price is not available, the average of the mid-point of the last bid
and ask prices of the Common Stock on such date from at least three nationally
recognized independent investment banking firms retained for this purpose by the
Company. A "Trading Day" means a day on which the Common Stock (A) is not
suspended from trading on any national or regional securities exchange or
association or over-the-counter market at the close of business and (B) has
traded at least once on the national or regional securities exchange or
association or over-the-counter market that is the primary market for the
trading of the Common Stock.

     In accordance with the terms of the Purchase Contract Agreement, the Holder
of this Corporate PIES Certificate may pay the Purchase Price for the shares of
Common Stock purchased pursuant to each Purchase Contract evidenced hereby by
effecting a Cash Settlement or an Early Settlement or a remarketing of the
related Pledged Preferred Stock. A Holder of Corporate PIES who does not effect,
on or prior to 11:00 a.m. New York City time on the fifth Business Day
immediately preceding the Purchase Contract Settlement Date, an effective Cash
Settlement or an Early Settlement, shall pay the Purchase Price for the shares
of Common Stock to be issued under the related Purchase Contract from the
proceeds of the sale of the related Pledged Preferred Stock held by the
Collateral Agent. Such sale will be made by the Remarketing Agent pursuant to
the terms of the Remarketing Agreement on the third Business Day prior to the
Purchase Contract Settlement Date. If, as provided in the Purchase Contract
Agreement, upon the occurrence of a Failed Remarketing the Collateral Agent, for
the benefit of the Company, exercises its rights as a secured creditor with
respect to the Pledged Preferred Stock related to this Corporate PIES
certificate, any accrued and unpaid dividends on such Pledged Preferred Stock
will become payable by the Company to the holder of this Corporate PIES
Certificate in the manner provided for in the Purchase Contract Agreement.

     The Company shall not be obligated to issue any shares of Common Stock in
respect of a Purchase Contract or deliver any certificates therefor to the
Holder unless it shall have received payment of the aggregate purchase price for
the shares of Common Stock to be purchased thereunder in the manner herein set
forth.

     Each Purchase Contract evidenced hereby and all obligations and rights of
the Company and the Holder thereunder shall terminate if a Termination Event
shall occur. Upon the occurrence of a Termination Event, the Company shall give
written notice to the Agent and to the Holders, at their addresses as they
appear in the Corporate PIES Register. Upon and after the occurrence of a
Termination Event, the Collateral Agent shall release the Pledged Preferred
Stock forming a part of each Corporate PIES from the Pledge. A Corporate PIES
shall thereafter represent the right to receive the Preferred Stock forming a
part of such Corporate PIES in accordance with the terms of the Purchase
Contract Agreement and the Pledge Agreement.

     Under the terms of the Pledge Agreement, the Agent will be entitled to
exercise the voting and any other consensual rights pertaining to the Pledged
Preferred Stock. Upon receipt of notice of any meeting at which holders of
Preferred Stock are entitled to vote or upon the solicitation of consents,
waivers or proxies of holders of Preferred Stock, the Agent shall, as soon as
practicable thereafter, mail to the Corporate PIES Holders a notice (a)
containing such information as is contained in the notice or solicitation, (b)
stating that each Corporate PIES Holder on the record

                                      A-6
<PAGE>

date set by the Agent therefor (which, to the extent possible, shall be the same
date as the record date for determining the holders of Preferred Stock entitled
to vote) shall be entitled to instruct the Agent as to the exercise of the
voting rights pertaining to the Preferred Stock constituting a part of such
Holder's Corporate PIES and (c) stating the manner in which such instructions
may be given. Upon the written request of the Corporate PIES Holders on such
record date, the Agent shall endeavor insofar as practicable to vote or cause to
be voted, in accordance with the instructions set forth in such requests, the
maximum aggregate liquidation preference of Preferred Stock as to which any
particular voting instructions are received. In the absence of specific
instructions from the Holder of a Corporate PIES, the Agent shall abstain from
voting the Preferred Stock evidenced by such Corporate PIES.

     The Corporate PIES Certificates are issuable only in registered form and
only in denominations of a single Corporate PIES and any integral multiple
thereof. The transfer of any Corporate PIES Certificate will be registered and
Corporate PIES Certificates may be exchanged as provided in the Purchase
Contract Agreement. The Corporate PIES Registrar may require a Holder, among
other things, to furnish appropriate endorsements and transfer documents
permitted by the Purchase Contract Agreement. No service charge shall be
required for any such registration of transfer or exchange, but the Company and
the Agent may require payment of a sum sufficient to cover any tax or other
governmental charge payable in connection therewith. A holder who elects to
substitute a Treasury Security for Preferred Stock thereby creating Treasury
PIES, shall be responsible for any fees or expenses payable in connection
therewith. Except as provided in the Purchase Contract Agreement, for so long as
the Purchase Contract underlying a Corporate PIES remains in effect, such
Corporate PIES shall not be separable into its constituent parts, and the rights
and obligations of the Holder of such Corporate PIES in respect of the Preferred
Stock and Purchase Contract constituting such Corporate PIES may be transferred
and exchanged only as a Corporate PIES. The holder of a Corporate PIES may
substitute for the Pledged Preferred Stock securing its obligation under the
related Purchase Contract Treasury Securities in an aggregate principal amount
equal to the aggregate liquidation preference of the Pledged Preferred Stock in
accordance with the terms of the Purchase Contract Agreement and the Pledge
Agreement. From and after such Collateral Substitution, the Security for which
such Pledged Treasury Securities secures the holder's obligation under the
Purchase Contract shall be referred to as a "Treasury PIES." A Holder may make
such Collateral Substitution only in integral multiples of 20 Corporate PIES for
20 Treasury PIES. Such Collateral Substitution may cause the equivalent
aggregate amount of this Certificate to be increased or decreased; provided,
however, this Corporate PIES Certificate shall not represent more than ____
Corporate PIES. All such adjustments to the equivalent amount of this Corporate
PIES Certificate shall be duly recorded by placing an appropriate notation on
the Schedule attached hereto.

     A Holder of Treasury PIES may recreate Corporate PIES by delivering to the
Securities Intermediary Preferred Stock with an aggregate liquidation preference
equal to the aggregate principal amount of the Pledged Treasury Securities in
exchange for the release of such Pledged Treasury Securities in accordance with
the terms of the Purchase Contract Agreement and the Pledge Agreement.

     The Company shall pay, on each Payment Date, the Contract Adjustment
Payments payable in respect of each Purchase Contract to the Person in whose
name the Corporate PIES

                                      A-7
<PAGE>

Certificate evidencing such Purchase Contract is registered at the close of
business on the Record Date for such Payment Date. Contract Adjustment Payments
will be payable at the office of the Agent in The City of New York or, at the
option of the Company, by check mailed to the address of the Person entitled
thereto at such address as it appears on the Corporate PIES Register.

     The Purchase Contracts and all obligations and rights of the Company and
the Holders thereunder, including, without limitation, the rights of the Holders
to receive and the obligation of the Company to pay any Contract Adjustment
Payments, shall immediately and automatically terminate, without the necessity
of any notice or action by any Holder, the Agent or the Company, if, on or prior
to the Purchase Contract Settlement Date, a Termination Event shall have
occurred. Upon the occurrence of a Termination Event, the Company shall promptly
but in no event later than two Business Days thereafter give written notice to
the Agent, the Collateral Agent and the Holders, at their addresses as they
appear in the Corporate PIES Register. Upon and after the occurrence of a
Termination Event, the Collateral Agent shall release the Preferred Stock from
the Pledge in accordance with the provisions of the Pledge Agreement.

     Subject to and upon compliance with the provisions of the Purchase Contract
Agreement, at the option of the Holder thereof, Purchase Contracts underlying
Securities may be settled early (an "Early Settlement") as provided in the
Purchase Contract Agreement. In order to exercise the right to effect Early
Settlement with respect to any Purchase Contracts evidenced by this Corporate
PIES Certificate, the Holder of this Corporate PIES Certificate shall deliver
this Corporate PIES Certificate to the Agent at the Corporate Trust Office duly
endorsed for transfer to the Company or in blank with the form of Election to
Settle Early set forth below duly completed and accompanied by payment in the
form of immediately available funds payable to the order of the Company in an
amount (the "Early Settlement Amount") equal to (i) the product of (A) the
Stated Amount times (B) the number of Purchase Contracts with respect to which
the Holder has elected to effect Early Settlement, plus (ii) if such delivery is
made with respect to any Purchase Contracts during the period from the close of
business on any Record Date for any Payment Date to the opening of business on
such Payment Date, an amount equal to the Contract Adjustment Payments payable
on such Payment Date with respect to such Purchase Contracts. Upon Early
Settlement of Purchase Contracts by a Holder of the related Securities, the
Pledged Preferred Stock underlying such Securities shall be released from the
Pledge as provided in the Pledge Agreement and the Holder shall be entitled to
receive a number of shares of Common Stock on account of each Purchase Contract
forming part of a Corporate PIES as to which Early Settlement is effected equal
to the Early Settlement Rate. The Early Settlement Rate shall initially be equal
to 1.11297 shares of Common Stock and shall be adjusted in the same manner and
at the same time as the Settlement Rate is adjusted as provided in the Purchase
Contract Agreement.

     Upon registration of transfer of this Corporate PIES Certificate, the
transferee shall be bound (without the necessity of any other action on the part
of such transferee, except as may be required by the Agent pursuant to the
Purchase Contract Agreement), under the terms of the Purchase Contract Agreement
and the Purchase Contracts evidenced hereby and the transferor shall be released
from the obligations under the Purchase Contracts evidenced by this Corporate
PIES Certificate. The Company covenants and agrees, and the Holder, by its
acceptance hereof, likewise covenants and agrees, to be bound by the provisions
of this paragraph.

                                      A-8
<PAGE>

     The Holder of this Corporate PIES Certificate, by its acceptance hereof,
authorizes the Agent to enter into and perform the related Purchase Contracts
forming part of the Corporate PIES evidenced hereby on its behalf as its
attorney-in-fact, expressly withholds any consent to the assumption (i.e.,
affirmance) of the Purchase Contracts by the Company or its trustee in the event
that the Company becomes the subject of a case under the Bankruptcy Code, agrees
to be bound by the terms and provisions thereof, covenants and agrees to perform
his obligations under such Purchase Contracts, consents to the provisions of the
Purchase Contract Agreement, authorizes the Agent to enter into and perform the
Purchase Contract Agreement and the Pledge Agreement on its behalf as its
attorney-in-fact, and consents to the Pledge of the Shares underlying this
Corporate PIES Certificate pursuant to the Pledge Agreement. The Holder further
covenants and agrees that, to the extent and in the manner provided in the
Purchase Contract Agreement and the Pledge Agreement, but subject to the terms
thereof, Proceeds from the Remarketing with respect to any of the Pledged
Preferred Stock or security entitlements thereto in respect of the aggregate
liquidation preference of the Pledged Preferred Stock on the Purchase Contract
Settlement Date shall be paid by the Collateral Agent to the Company in
satisfaction of such Holder's obligations under such Purchase Contract and such
Holder shall acquire no right, title or interest in such payments.

     Subject to certain exceptions, the provisions of the Purchase Contract
Agreement may be amended with the consent of the Holders of a majority of the
Purchase Contracts.

     The Purchase Contracts shall for all purposes be governed by, and construed
in accordance with, the laws of the State of New York.

     The Company, the Agent and its Affiliates and any agent of the Company or
the Agent may treat the Person in whose name this Corporate PIES Certificate is
registered as the owner of the Corporate PIES evidenced hereby for the purpose
of receiving payments of dividends payable quarterly on the Preferred Stock
receiving payments of Contract Adjustment Payments, performance of the Purchase
Contracts and for all other purposes whatsoever, whether or not any payments in
respect thereof be overdue and notwithstanding any notice to the contrary, and
neither the Company, the Agent nor any such agent shall be affected by notice to
the contrary.

     The Purchase Contracts shall not, prior to the settlement thereof, entitle
the Holder to any of the rights of a holder of shares of Common Stock.

     A copy of the Purchase Contract Agreement is available for inspection at
the offices of the Agent.

                                  TREASURY PIES

     This Treasury PIES Certificate certifies that Cede & Co. is the registered
Holder of the number of Treasury PIES set forth above. Each Treasury PIES
consists of (i) a 1/20 undivided beneficial ownership interest of a Treasury
Security having a principal amount at maturity equal to $1,000, subject to the
Pledge of such Treasury Security by such Holder pursuant to the Pledge
Agreement, and (ii) the rights and obligations of the Holder under one Purchase
Contract with Bank United Corp., a Delaware corporation (the "Company"). All
capitalized terms used herein which are defined in the Purchase Contract
Agreement (as defined on the reverse hereof) have the meaning set forth therein.

     Pursuant to the Pledge Agreement, the Treasury Securities constituting part
of each Treasury PIES evidenced hereby have been pledged to the Collateral
Agent, for the benefit of the

<PAGE>

Company, to secure the obligations of the Holder under the Purchase Contract
comprising a portion of such Treasury PIES.

     Each Purchase Contract evidenced hereby obligates the Holder of this
Treasury PIES Certificate to purchase, and the Company, to sell, on August 16,
2002 (the "Purchase Contract Settlement Date"), at a price equal to $50 in cash
(the "Stated Amount"), a number of Common Shares, par value $0.01 ("Common
Stock"), of the Company equal to the Settlement Rate, unless on or prior to the
Purchase Contract Settlement Date there shall have occurred a Termination Event
or an Early Settlement with respect to the Treasury PIES of which such Purchase
Contract is a part, all as provided in the Purchase Contract Agreement and more
fully described on the reverse hereof. The purchase price for the shares of
Common Stock purchased pursuant to each Purchase Contract evidenced hereby, if
not paid earlier, shall be paid on the Purchase Contract Settlement Date by
application of the Proceeds from the Treasury Securities pledged to secure the
obligations under such Purchase Contract in accordance with the terms of the
Pledge Agreement.

     The Company shall pay on each Payment Date in respect of each Purchase
Contract evidenced hereby an amount (the "Contract Adjustment Payments") equal
to (a) if a Reset Transaction has not occurred, 0.75% per annum of the Stated
Amount or (b) following the occurrence of a Reset Transaction, the Adjusted
Contract Adjustment Payment Rate related to such Reset Transaction until any
such succeeding Reset Transaction shall occur (computed on the basis of (i) for
any full quarterly period, a 360-day year of twelve 30-day months and (ii) for
any period shorter than a full quarterly period, a 30-day month and for periods
less than a month, the actual number of days elapsed per 30-day period), as the
case may be. Such Contract Adjustment Payments shall be payable to the Person in
whose name this Treasury PIES Certificate (or a Predecessor Treasury PIES
Certificate) is registered at the close of business on the Record Date for such
Payment Date.

     Contract Adjustment Payments will be payable at the office of the Agent in
The City of New York or, at the option of the Company, by check mailed to the
address of the Person entitled thereto as such address appears on the Treasury
PIES Register.

     Reference is hereby made to the further provisions 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
Agent by manual signature, this Treasury PIES Certificate shall not be entitled
to any benefit under the Pledge Agreement or the Purchase Contract Agreement or
be valid or obligatory for any purpose.

<PAGE>


                     (REVERSE OF TREASURY PIES CERTIFICATE)

     Each Purchase Contract evidenced hereby is governed by a Purchase Contract
Agreement, dated as of August 10, 1999 (as may be supplemented from time to
time, the "Purchase Contract Agreement") between the Company and the First
National Bank of Chicago, as Purchase Contract Agent (including its successors
thereunder, herein called the "Agent"), to which the Purchase Contract Agreement
and supplemental agreements thereto reference is hereby made for a description
of the respective rights, limitations of rights, obligations, duties and
immunities thereunder of the Agent, the Company and the Holders and of the terms
upon which the Treasury PIES Certificates are, and are to be, executed and
delivered.

     Each Purchase Contract evidenced hereby obligates the Holder of this
Treasury PIES Certificate to purchase, and the Company to sell, on the Purchase
Contract Settlement Date at a price equal to the Stated Amount (the "Purchase
Price") a number of shares of Common Stock of the Company equal to the
Settlement Rate, unless on or prior to the Purchase Contract Settlement Date,
there shall have occurred a Termination Event with respect to the Security of
which such Purchase Contract is a part or an Early Settlement shall have
occurred. The "Settlement Rate" is equal to (a) if the Applicable Market Value
(as defined below) is equal to or greater than $44.9250 (the "Threshold
Appreciation Price"), 1.11297 shares of Common Stock per Purchase Contract, (b)
if the Applicable Market Value is less than the Threshold Appreciation Price but
is greater than $37.4375, the number of shares of Common Stock per Purchase
Contract equal to the Stated Amount divided by the Applicable Market Value and
(c) if the Applicable Market Amount is less than or equal to $37.4375, then
1.33556 shares of Common Stock per Purchase Contract, in each case subject to
adjustment as provided in the Purchase Contract Agreement. No fractional shares
of Common Stock will be issued upon settlement of Purchase Contracts, as
provided in the Purchase Contract Agreement.

     Each Purchase Contract evidenced hereby, which is settled either through
Early Settlement or Cash Settlement, shall obligate the Holder of the related
Treasury PIES to purchase at the Purchase Price for cash, and the Company to
sell, a number of newly issued shares of Common Stock equal to the Early
Settlement Rate or the Settlement Rate, as applicable.

     The "Applicable Market Value" means the average of the Closing Prices per
share of Common Stock on each of the 20 Trading Days ending on the third Trading
Day immediately preceding the Purchase Contract Settlement Date. The "Closing
Price" of the Common Stock on any date of determination means the (i) closing
sale price (or, if no closing price is reported, the last reported sale price)
of the Common Stock on the Nasdaq National Market on such date, (ii) if the
Common Stock is not listed for trading on the Nasdaq National Market on any such
date, the closing sale price as reported in the composite transactions for the
principal United States securities exchange on which the Common Stock is so
listed, (iii) if the Common Stock is not so reported, the last quoted bid price
for the Common Stock in the over-the-counter market as reported by the National
Quotation Bureau or similar organization or (iv) if such bid price is not
available, the average of the mid-point of the last bid and ask prices of the
Common Stock on such date from at least three nationally recognized independent
investment banking firms retained for this purpose by the Company. A "Trading
Day" means a day on which the Common Stock (A) is not suspended from trading on
any national or regional securities exchange or association or over-the-counter
market at the close of business and (B) has traded at least once on

                                      B-5
<PAGE>

the national or regional securities exchange or association or over-the-counter
market that is the primary market for the trading of the Common Stock.

     In accordance with the terms of the Purchase Contract Agreement, the Holder
of this Treasury PIES shall pay the Purchase Price for the shares of Common
Stock purchased pursuant to each Purchase Contract evidenced hereby either by
effecting a Cash Settlement or an Early Settlement of each such Purchase
Contract or by applying a principal amount of the Pledged Treasury Securities
underlying such Holder's Treasury PIES equal to the Stated Amount of such
Purchase Contract to the purchase of the Common Stock. A Holder of Treasury PIES
who does not effect, on or prior to 11:00 a.m. New York City time on the
Business Day immediately preceding the Purchase Contract Settlement Date, an
effective Cash Settlement or an Early Settlement, shall pay the Purchase Price
for the shares of Common Stock to be issued under the related Purchase Contract
from the proceeds of the Pledged Treasury Securities.

     The Company shall not be obligated to issue any shares of Common Stock in
respect of a Purchase Contract or deliver any certificates therefor to the
Holder unless it shall have received payment of the aggregate purchase price for
the shares of Common Stock to be purchased thereunder in the manner herein set
forth.

     Each Purchase Contract evidenced hereby and all obligations and rights of
the Company and the Holder thereunder shall terminate if a Termination Event
shall occur. Upon the occurrence of a Termination Event, the Company shall give
written notice to the Agent and to the Holders, at their addresses as they
appear in the Treasury PIES Register. Upon and after the occurrence of a
Termination Event, the Collateral Agent shall release the Pledged Treasury
Securities (as defined in the Pledge Agreement) forming a part of each Treasury
PIES. A Treasury PIES shall thereafter represent the right to receive the
interest in the Treasury Security forming a part of such Treasury PIES, in
accordance with the terms of the Purchase Contract Agreement and the Pledge
Agreement.

     The Treasury PIES Certificates are issuable only in registered form and
only in denominations of a single Treasury PIES and any integral multiple
thereof. The transfer of any Treasury PIES Certificate will be registered and
Treasury PIES Certificates may be exchanged as provided in the Purchase Contract
Agreement. The Treasury PIES Registrar may require a Holder, among other things,
to furnish appropriate endorsements and transfer documents permitted by the
Purchase Contract Agreement. No service charge shall be required for any such
registration of transfer or exchange, but the Company and the Agent may require
payment of a sum sufficient to cover any tax or other governmental charge
payable in connection therewith. A Holder who elects to substitute Preferred
Stock for Treasury Securities, thereby recreating Corporate PIES, shall be
responsible for any fees or expenses associated therewith. Except as provided in
the Purchase Contract Agreement, for so long as the Purchase Contract underlying
a Treasury PIES remains in effect, such Treasury PIES shall not be separable
into its constituent parts, and the rights and obligations of the Holder of such
Treasury PIES in respect of the Treasury Security and the Purchase Contract
constituting such Treasury PIES may be transferred and exchanged only as a
Treasury PIES. A Holder of Treasury PIES may recreate Corporate PIES by
delivering to the Collateral Agent Preferred Stock with an aggregate liquidation
preference equal to the aggregate principal amount at maturity of the Pledged
Treasury Securities in exchange for the release of such Pledged Treasury
Securities in accordance with the terms of

                                      B-6
<PAGE>

the Purchase Contract Agreement and the Pledge Agreement. From and after such
substitution, the Holder's Security shall be referred to as an "Corporate PIES."
Such substitution may cause the equivalent aggregate principal amount of this
Certificate to be increased or decreased; provided, however, this Treasury PIES
Certificate shall not represent more than ____ Treasury PIES. All such
adjustments to the equivalent aggregate principal amount of this Treasury PIES
Certificate shall be duly recorded by placing an appropriate notation on the
Schedule attached hereto.

     A Holder of a Corporate PIES may recreate a Treasury PIES by delivering to
the Collateral Agent Treasury Securities in an aggregate principal amount equal
to the aggregate liquidation preference of the Pledged Preferred Stock in
exchange for the release of such Pledged Preferred Stock in accordance with the
terms of the Purchase Contract Agreement and the Pledge Agreement. Any such
recreation of a Treasury PIES may be effected only in multiples of 20 Corporate
PIES for 20 Treasury PIES.

     The Company shall pay, on each Payment Date, the Contract Adjustment
Payments payable in respect of each Purchase Contract to the Person in whose
name the Treasury PIES Certificate evidencing such Purchase Contract is
registered at the close of business on the Record Date for such Payment Date.
Contract Adjustment Payments will be payable at the office of the Agent in The
City of New York or, at the option of the Company, by check mailed to the
address of the Person entitled thereto at such address as it appears on the
Treasury PIES Register.

     The Purchase Contracts and all obligations and rights of the Company and
the Holders thereunder, including, without limitation, the rights of the Holders
to receive and the obligation of the Company to pay Contract Adjustment
Payments, shall immediately and automatically terminate, without the necessity
of any notice or action by any Holder, the Agent or the Company, if, on or prior
to the Purchase Contract Settlement Date, a Termination Event shall have
occurred. Upon the occurrence of a Termination Event, the Company shall promptly
but in no event later than two Business Days thereafter give written notice to
the Agent, the Collateral Agent and the Holders, at their addresses as they
appear in the Treasury PIES Register. Upon the occurrence of a Termination
Event, the Collateral Agent shall release the Treasury Securities from the
Pledge in accordance with the provisions of the Pledge Agreement.

     Subject to and upon compliance with the provisions of the Purchase Contract
Agreement, at the option of the Holder thereof, Purchase Contracts underlying
Securities may be settled early (an "Early Settlement") as provided in the
Purchase Contract Agreement. In order to exercise the right to effect Early
Settlement with respect to any Purchase Contracts evidenced by this Treasury
PIES the Holder of this Treasury PIES Certificate shall deliver this Treasury
PIES Certificate to the Agent at the Corporate Trust Office duly endorsed for
transfer to the Company or in blank with the form of Election to Settle Early
set forth below duly completed and accompanied by payment in the form of
immediately available funds payable to the order of the Company in an amount
(the "Early Settlement Amount") equal to (i) the product of (A) $50 times (B)
the number of Purchase Contracts with respect to which the Holder has elected to
effect Early Settlement, plus (ii) if such delivery is made with respect to any
Purchase Contracts during the period from the close of business on any Record
Date for any Payment Date to the opening of business on such Payment Date, an
amount equal to the Contract Adjustment Payments payable, if any, on such
Payment Date with respect to such Purchase Contracts. Upon Early Settlement of
Purchase Contracts by a Holder of the related Securities, the Pledged Treasury
Securities

                                      B-7
<PAGE>

underlying such Securities shall be released from the Pledge as provided in the
Pledge Agreement and the Holder shall be entitled to receive a number of shares
of Common Stock on account of each Purchase Contract forming part of a Treasury
PIES as to which Early Settlement is effected equal to 1.11297 shares of Common
Stock per Purchase Contract (the "Early Settlement Rate"). The Early Settlement
Rate shall be adjusted in the same manner and at the same time as the Settlement
Rate is adjusted as provided in the Purchase Contract Agreement.

     Upon registration of transfer of this Treasury PIES Certificate, the
transferee shall be bound (without the necessity of any other action on the part
of such transferee, except as may be required by the Agent pursuant to the
Purchase Contract Agreement), under the terms of the Purchase Contract Agreement
and the Purchase Contracts evidenced hereby and the transferor shall be released
from the obligations under the Purchase Contracts evidenced by this Treasury
PIES Certificate. The Company covenants and agrees, and the Holder, by its
acceptance hereof, likewise covenants and agrees, to be bound by the provisions
of this paragraph.

     The Holder of this Treasury PIES Certificate, by its acceptance hereof,
authorizes the Agent to enter into and perform the related Purchase Contracts
forming part of the Treasury PIES evidenced hereby on its behalf as its
attorney-in-fact, expressly withholds any consent to the assumption (i.e.,
affirmance) of the Purchase Contracts by the Company or its trustee in the event
that the Company becomes the subject of a case under the Bankruptcy Code, agrees
to be bound by the terms and provisions thereof, covenants and agrees to perform
its obligations under such Purchase Contracts, consents to the provisions of the
Purchase Contract Agreement, authorizes the Agent to enter into and perform the
Purchase Contract Agreement and the Pledge Agreement on its behalf as its
attorney-in-fact, and consents to the Pledge of the Treasury Securities
underlying this Treasury PIES Certificate pursuant to the Pledge Agreement. The
Holder further covenants and agrees, that, to the extent and in the manner
provided in the Purchase Contract Agreement and the Pledge Agreement, but
subject to the terms thereof, payments in respect of the aggregate principal
amount of the Pledged Treasury Securities on the Purchase Contract Settlement
Date shall be paid by the Collateral Agent to the Company in satisfaction of
such Holder's obligations under such Purchase Contract and such Holder shall
acquire no right, title or interest in such payments.

     Subject to certain exceptions, the provisions of the Purchase Contract
Agreement may be amended with the consent of the Holders of a majority of the
Purchase Contracts.

     The Purchase Contracts shall for all purposes be governed by, and construed
in accordance with, the laws of the State of New York.

     The Company, the Agent and its Affiliates and any agent of the Company or
the Agent may treat the Person in whose name this Treasury PIES Certificate is
registered as the owner of the Treasury PIES evidenced hereby for the purpose of
receiving payments of interest on the Treasury Securities, receiving payments of
Contract Adjustment Payments, performance of the Purchase Contracts and for all
other purposes whatsoever, whether or not any payments in respect thereof be
overdue and notwithstanding any notice to the contrary, and neither the Company,
the Agent nor any such agent shall be affected by notice to the contrary.

     The Purchase Contracts shall not, prior to the settlement thereof, entitle
the Holder to any of the rights of a holder of shares of Common Stock.

         (c) If a Holder of a Treasury PIES notifies the Purchase Contract Agent

         Section 5.6 Early Settlement. Upon written notice to the Collateral
Agent by the Purchase Contract Agent that one or more Holders of Securities have
elected to effect Early Settlement of their respective obligations under the
Purchase Contracts forming a part of such Securities in accordance with the
terms of the Purchase Contracts and the Purchase Contract Agreement (setting
forth the number of such Purchase Contracts as to which such Holders have
elected to effect Early Settlement), and that the Purchase Contract Agent has
received from such Holders, and paid to the Company as confirmed in writing by
the Company, the related Early Settlement Amounts pursuant to the terms of the
Purchase Contracts and the Purchase Contract Agreement and that all conditions
to such Early Settlement have been satisfied, then the Collateral Agent shall
release from the Pledge, upon three Business Days' written notice to the
Collateral Agent , (a) Pledged Preferred Stock, in the case of a Holder of
Corporate PIES, or (b0 Pledged Treasury Securities, in the case of a Holder of
Treasury PIES, with a Value equal to the product of (i) the Stated Amount times
(ii) the number of Purchase Contracts as to which such Holders have elected to
effect Early Settlement and shall instruct the Securities Intermediary to
Transfer all such Pledged Preferred Stock or Pledged Treasury Securities, as the
case may be, to the Purchase Contract Agent for the benefit of such Holders, in
each case free and clear of the Pledge created hereby, for distribution to such
Holders in accordance with their respective interests.

         Section 5.7 Application of Proceeds Settlement. (a) If a Holder of
Corporate PIES has not elected to make an effective Cash Settlement by notifying
the Purchase Contract Agent in the manner provided for in Section 5.4(a)(i) in
the Purchase Contract Agreement, or has given such notice but failed to deliver
the required cash prior to 11:00 a.m., New York City time, on the fifth Business
Day immediately preceding the Purchase Contract Settlement Date, such Holder
shall be deemed to have elected to pay for the shares of Common Stock to be
issued under such Purchase Contract(s) from the Proceeds of the related Pledged
Preferred Stock. In such event, the Collateral Agent shall instruct the
Securities Intermediary to Transfer the related Pledged Preferred Stock to the
Remarketing Agent for remarketing. Upon receiving such Pledged Preferred Stock,
the Remarketing Agent, pursuant to the terms of the Remarketing Agreement, will
use its reasonable efforts to remarket such Pledged Preferred Stock on such date
at a price of 100.50% of the aggregate liquidation preference of such Pledged
Preferred Stock. The Remarketing Agent will deposit in the Collateral Account
the portion of the Proceeds of such remarketing equal to 100% the aggregate
liquidation preference of the remarketed Pledged Preferred Stock and, pursuant
to the Remarketing Agreement, shall retain the portion of the Proceeds equal to
0.50% of the aggregate liquidation preference of the remarketed Pledged
Preferred Stock. On the Purchase Contract Settlement Date, upon three Business
Days' written notice to the Collateral Agent the Collateral Agent shall instruct
the Securities Intermediary to apply a portion of the Proceeds from such
remarketing equal to the aggregate liquidation preference of such Pledged
Preferred Stock to satisfy in full the obligations of such Holders of Corporate
PIES to pay the Purchase Price to purchase the Common Stock under the related
Purchase Contracts. The balance of the Proceeds from such remarketing on deposit
in the Collateral Account shall be transferred to the Purchase Contract Agent
for distribution to the Holders in accordance with their respective interests.
If the Remarketing Agent advises the Collateral Agent in writing that there has
been a Failed Remarketing, thus resulting in an event of default under the
Purchase Contract Agreement and hereunder, the Collateral Agent, for the
<PAGE>
                                       13



benefit of the Company shall, at the written direction of the Company, dispose
of the Pledged Preferred Stock in accordance with applicable law and satisfy
in full, from such disposition, such Holders' obligations to pay the Purchase
Price for the Common Stock.

         (b) If a Holder of Treasury PIES has not elected to make an effective
cash settlement by notifying the Purchase Contract Agent in the manner provided
for in Section 5.4(d)(i) of the Purchase Contract Agreement, or has given such
notice but failed to make such payment in the manner required by Section
5.4(d)(ii) of the Purchase Contract Agreement, such Holder shall be deemed to
have elected to pay for the shares of Common Stock to be issued under such
Purchase Contract(s) from the Proceeds of the related Pledged Treasury
Securities. Upon maturity of the Pledged Treasury Securities, the Securities
Intermediary, at the written direction of the Collateral Agent, shall invest the
Cash Proceeds of the maturing Pledged Treasury Securities in Permitted
Investments. Without receiving any instruction from any such Holder of Treasury
PIES, the Collateral Agent shall apply the Proceeds of the related Pledged
Treasury Securities to the settlement of such Purchase Contracts on the Purchase
Contract Settlement Date. In the event the sum of the Proceeds from the related
Pledged Treasury Securities and the investment earnings from the investment in
Permitted Investments is in excess of the aggregate Purchase Price of the
Purchase Contracts being settled thereby, the Collateral Agent shall instruct
the Securities Intermediary to distribute such excess, when received, to the
Purchase Contract Agent for the benefit of such Holders for distribution to such
Holders in accordance with their respective interests.

           Section 6. Voting Rights-Pledged Preferred Stock. The Purchase
Contract Agent will only exercise any voting rights upon written direction and
indemnity of holders, or may refrain from exercising, any and all voting and
other consensual rights pertaining to the Pledged Preferred Stock or any part
thereof for any purpose not inconsistent with the terms of this Agreement and in
accordance with the terms of the Purchase Contract Agreement; provided, that the
Purchase Contract Agent shall not exercise or, as the case may be, shall not
refrain from exercising such right if, in the judgment of the Purchase Contract
Agent, such action would impair or otherwise have a material adverse effect on
the value of all or any of the Pledged Preferred Stock; and provided, further,
that the Purchase Contract Agent shall give the Company and the Collateral Agent
at least five days' prior written notice of the manner in which it intends to
exercise any such right. Upon receipt of any notices and other communications in
respect of any Pledged Preferred Stock, including notice of any meeting at which
holders of the Shares of Preferred Stock are entitled to vote or solicitation of
consents, waivers or proxies of holders of the Shares of Preferred Stock, the
Collateral Agent shall use reasonable efforts to send promptly to the Purchase
Contract Agent such notice or communication, and as soon as reasonably
practicable after receipt of a written request therefor from the Purchase
Contract Agent, execute and deliver to the Purchase Contract Agent such proxies
and other instruments in respect of such Pledged Preferred Stock (in form and
substance satisfactory to the Collateral Agent) as are prepared by the Purchase
Contract Agent with respect to the Pledged Preferred Stock.

Treasury Securities as provided in Section 3 hereof, in satisfaction of the
Obligations of the Holder of the Securities of which such Pledged Treasury
Securities is a part under the related Purchase Contracts, the inability to make
such payments shall constitute an event of default hereunder and the Collateral
Agent shall have and may exercise, with reference to such Pledged Treasury
Securities and such Obligations of such Holder, any and all of the rights and
remedies available to a secured party under the Code and the TRADES Regulations
after default by a debtor, and as otherwise granted herein or under any other
law.

event such Holder becomes the Holder of a Treasury PIES, agrees that, from time
to time, upon the written request of the Collateral Agent, the Purchase Contract
Agent or such Holder shall execute and deliver such further documents and do
such other acts and things as the Collateral Agent, upon notice by the Company,
may reasonably request in order to maintain the Pledge, and the perfection and
priority thereof, and to confirm the rights of the Collateral Agent hereunder.
The Purchase Contract Agent shall have no liability to any Holder for executing
any documents or taking any such acts requested by the Collateral Agent
hereunder, except for liability for its own negligent acts, its own negligent
failure to act or its own willful misconduct.

         Section 7.2 Substitutions. Whenever a Holder has the right to
substitute Treasury Securities, Shares of Preferred Stock or security
entitlements to either of them for financial assets held in the Collateral
Account, such substitution shall not constitute a novation of the security
interest created hereby.

                           hereof;

                           hereunder and under applicable law for perfection of

                           and

                  (d)      the execution and performance by the Holder of its
                           obligations under this Agreement will not result in
                           the creation of any security interest, lien or other
                           encumbrance on the Collateral other than the security

                  (b)      neither the Purchase Contract Agent nor such Holders
                           will sell or otherwise dispose (or attempt to
                           dispose) of the Collateral or any part of it except
                           for the beneficial interest therein, subject to the

hereto beyond the specific terms hereof; (b) shall not be responsible for any
recitals contained in this Agreement, or in any certificate or other document
referred to or provided for in, or received by it under, this Agreement, the

(other than as against the Collateral Agent), the Securities or the Purchase
Contract Agreement or any other document referred to or provided for herein or

proceeding for the realization of any right or remedy available to the
Collateral Agent, or of exercising any power conferred on the Collateral Agent,
or to direct the taking or refraining from taking of any action authorized by
this Agreement; provided, however, that (i) such direction shall not conflict
with the provisions of any law or of this Agreement and (ii) the Collateral
Agent shall be adequately indemnified as provided herein. Nothing in this
Section 9.2 shall impair the right of the Collateral Agent in its discretion to
take any action or omit to take any action which it deems proper and which is
not inconsistent with such direction.

         Section 9.3 Reliance by Collateral Agent and Securities Intermediary.
Each of the Securities Intermediary and the Collateral Agent shall be entitled
to rely upon any certification, order, judgment, opinion, notice or other
communication (including, without limitation, any thereof by telephone or

sent by or on behalf of the proper Person or Persons (without being required to
determine the correctness of any fact stated therein) and upon advice and
statements of legal counsel and other experts selected by the Collateral Agent
and the Securities Intermediary. As to any matters not expressly provided for by

investments in and generally engage in any kind of banking, trust or other
business with the Purchase Contract Agent, any other Person interested herein
and any Holder of Securities (and any of their respective subsidiaries or
affiliates) as if it were not acting as the Collateral Agent, and the Collateral
Agent, the Securities Intermediary and their affiliates may accept fees and
other consideration from the Purchase Contract Agent and any Holder of
Securities without having to account for the same to the Company; provided that
each of the Securities Intermediary and the Collateral Agent covenants and
agrees with the Company that it shall not accept, receive or permit there to be
created in favor of itself and shall take no affirmative action to permit there
to be created in favor of any other Person, any security interest, lien or other
encumbrance of any kind in or upon the Collateral other than the lien created by
the Pledge.

         Section 9.5 Non-Reliance on Collateral Agent and Securities
Intermediary. Neither the Securities Intermediary nor the Collateral Agent shall
be required to keep itself informed as to the performance or observance by the
Purchase Contract Agent or any Holder of Securities of this Agreement, the

provided for herein or therein or to inspect the properties or books of the
Purchase Contract Agent or any Holder of Securities. Neither the Collateral
Agent nor the Securities Intermediary shall have any duty or responsibility to
provide the Company with any credit or other information concerning the affairs,
financial condition or business of the Purchase Contract Agent or any Holder of
Securities (or any of their respective affiliates) that may come into the

<PAGE>
                                       18


possession of the Collateral Agent or the Securities Intermediary or any of
their respective affiliates.

         Section 9.6 Compensation and Indemnity. The Company agrees: (i) to pay
the Collateral Agent and the Securities Intermediary from time to time such
compensation as shall be agreed in writing between the Company and the

services rendered by them hereunder and (ii) to indemnify the Collateral Agent,
the Securities Intermediary and the Purchase Contract Agent for, and to hold
each of them harmless from and against, any loss, liability or reasonable
out-of-pocket expense incurred without negligence, willful misconduct or bad
faith on its part, arising out of or in connection with the acceptance or
administration of its powers and duties under this Agreement, including the
reasonable out-of-pocket costs and expenses (including reasonable fees and
expenses of counsel) of defending itself against any claim or liability in
connection with the exercise or performance of such powers and duties. The
provisions of this Section shall survive the termination of this Agreement.

         Section 9.7 Failure to Act. In the event of any ambiguity in the
provisions of this Agreement or any dispute between or conflicting claims by or
among the parties hereto or any other Person with respect to any funds or
property deposited hereunder, the Collateral Agent and the Securities
Intermediary shall be entitled, after prompt notice to the Company and the
Purchase Contract Agent, at its sole option, to refuse to comply with any and
all claims, demands or instructions with respect to such property or funds so
long as such dispute or conflict shall continue, and the Collateral Agent and
the Securities Intermediary shall not be or become liable in any way to any of
the parties hereto for its failure or refusal to comply with such conflicting
claims, demands or instructions. The Collateral Agent and the Securities
Intermediary shall be entitled to refuse to act until either (i) such
conflicting or adverse claims or demands shall have been finally determined by a
court of competent jurisdiction or settled by agreement between the conflicting
parties as evidenced in a writing satisfactory to the Collateral Agent or the
Securities Intermediary or (ii) the Collateral Agent or the Securities
Intermediary shall have received security or an indemnity satisfactory to it

Collateral Agent and the Securities Intermediary may in addition elect to
commence an interpleader action or seek other judicial relief or orders as the
Collateral Agent or the Securities Intermediary may deem necessary.
Notwithstanding anything contained herein to the contrary, neither the
Collateral Agent nor the Securities Intermediary shall be required to take any
action that is in its opinion contrary to law or to the terms of this Agreement,
or which would in its opinion subject it or any of its officers, employees or
directors to liability.

become vested with all the rights, powers, privileges and duties of the retiring
Collateral Agent, and the retiring Collateral Agent shall take all appropriate
action to transfer any money and property held by it hereunder (including the
Collateral) to such successor Collateral Agent. The retiring Collateral Agent
shall, upon such succession, be discharged from its duties and obligations as
Collateral Agent hereunder. After any retiring Collateral Agent's resignation
hereunder as Collateral Agent, the provisions of this Section 9 shall continue
in effect for its benefit in respect of any actions taken or omitted to be taken
by it while it was acting as the Collateral Agent.

any time by giving notice thereof to the Company and the Purchase Contract Agent
as attorney-in-fact for the Holders of Securities, (ii) the Securities
Intermediary may be removed at any time by the Company and (iii) if the
Securities Intermediary fails to perform any of its material obligations
hereunder in any material respect for a period of not less than 20 days after
receiving written notice of such failure by the Purchase Contract Agent and such
failure shall be continuing, the Securities Intermediary may be removed by the
Purchase Contract Agent. The Purchase Contract Agent shall promptly notify the
Company of any removal of the Securities Intermediary pursuant to clause (iii)
of the immediately preceding sentence. Upon any such resignation or removal, the
Company shall have the right to appoint a successor Securities Intermediary. If
no successor Securities Intermediary shall have been so appointed and shall have
accepted such appointment within 30 days after the retiring Securities
Intermediary's giving of notice of resignation or such removal, then the
retiring Securities Intermediary may petition any court of competent
jurisdiction for the appointment of a successor Securities Intermediary. The
Securities Intermediary shall be a bank which has an office in New York, New
York with a combined capital and surplus of at least $50,000,000 and shall not
be the Purchase Contract Agent or any of its affiliates. Upon the acceptance of
any appointment as Securities Intermediary hereunder by a successor Securities
Intermediary, such successor Securities Intermediary shall thereupon succeed to
and become vested with all the rights, powers, privileges and duties of the
retiring Securities Intermediary, and the retiring Securities Intermediary shall
take all appropriate action to transfer any money and property held by it
hereunder (including the Collateral) to such successor Securities Intermediary.
The retiring Securities Intermediary shall, upon such succession, be discharged
from its duties and obligations as Securities Intermediary hereunder. After any
retiring Securities Intermediary's resignation hereunder as Securities
Intermediary, the provisions of this Section 9 shall continue in effect for

<PAGE>
                                       20

its benefit in respect of any actions taken or omitted to be taken by it while
it was acting as the Securities Intermediary.

         Section 9.9 Right to Appoint Agent or Advisor. The Collateral Agent
shall have the right to appoint agents or advisors in connection with any of its
duties hereunder, and the Collateral Agent shall not be liable for any action
taken or omitted by, or in reliance upon the advice of, such agents or advisors
selected in good faith. The appointment of agents pursuant to this Section 9.9
shall be subject to prior consent of the Company, which consent shall not be
unreasonably withheld.

         Section 9.10 Survival. The provisions of this Section 9 shall survive
termination of this Agreement and the resignation or removal of the Collateral
Agent or the Securities Intermediary.

         Section 9.11 Exculpation. Anything in this Agreement to the contrary
notwithstanding, in no event shall the Collateral Agent or the Securities
Intermediary or their officers, directors, employees or agents be liable under
this Agreement to any third party for indirect, special, punitive, or
consequential loss or damage of any kind whatsoever, including lost profits,
whether or not the likelihood of such loss or damage was known to the Collateral
Agent or the Securities Intermediary, or any of them, incurred without any act
or deed that is found to be attributable to gross negligence or willful
misconduct on the part of the Collateral Agent or the Securities Intermediary.

this Agreement, in form satisfactory to the Company, the Collateral Agent, the
Securities Intermediary and the Purchase Contract Agent, 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;

                  (2) to add to the covenants of the Company for the benefit of
         the Holders, or to surrender any right or power herein conferred upon
         the Company, so long as such covenants or such surrender do not
         adversely affect the validity, perfection or priority of the Pledge
         created hereunder;

                  (3) to evidence and provide for the acceptance of appointment
         hereunder by a successor Collateral Agent, Securities Intermediary or
         Purchase Contract Agent; or

                  (4) to cure any ambiguity (or formal defect), to correct or
         supplement any provisions herein which may be inconsistent with any
         other such provisions herein, or to make any other provisions with
         respect to such matters or questions arising under this Agreement,

Securities Intermediary and the Collateral Agent may amend this Agreement for
the purpose of modifying in any manner the provisions of this Agreement or the
rights of the Holders in respect of the Securities; provided, however, that no
such supplemental agreement shall, without the unanimous consent of the Holders
of each Outstanding Security adversely affected thereby,

                  (1) change the amount or type of Collateral underlying a
         Security (except for the rights of holders of Corporate PIES to
         substitute the Treasury Securities for the Pledged Preferred Stock or
         the rights of Holders of Treasury PIES to substitute Shares of
         Preferred Stock for the Pledged Treasury Securities), impair the right
         of the Holder of any Security to receive distributions on the

         the Purchase Contract Agreement if such action were effected by an
         agreement supplemental thereto; or

                  (3) reduce the percentage of Purchase Contracts the consent
         of whose Holders is required for any such amendment;

provided that if any amendment or proposal referred to above would adversely
affect only the Corporate PIES or only the Treasury PIES, then only the affected

proposal shall not be effective except with the consent of Holders of not less
than a majority of such class; provided that the unanimous consent of the
Holders of each outstanding Purchase Contract of such class affected thereby
shall be required to approve any amendment or proposal specified in clauses (1)
- - (3) above.

permitted by this Section, the Collateral Agent, the Securities Intermediary and
the Purchase Contract Agent shall be entitled to receive and (subject to Section

Contract Agent and the Company, to any such amendment may be prepared and
executed by the Company and authenticated, executed on behalf of the Holders and
delivered by the Purchase Contract Agent in accordance with the Purchase

Section 11.  Miscellaneous.

         Section 11.1 No Waiver. No failure on the part of the Collateral Agent
or any of its agents to exercise, and no course of dealing with respect to, and
no delay in exercising, any right, power or remedy hereunder shall operate as a

     Bank United Corp., a Delaware corporation (the "Company"), is issuing today
2,000,000 shares of its Series B Preferred Stock, liquidation preference of $50
per share (the "Preferred Stock"), pursuant to a Certificate of Designations
filed with the Secretary of State of the State of Delaware (the "Certificate of
Designations"). Capitalized terms used but not defined in this Remarketing
Agreement (this "Agreement") shall have the meanings set forth in the
Certificate of Designations.

     The Remarketing (as defined below) of the Preferred Stock is provided for
in the Certificate of Designations. As used in this Agreement, the term
"Remarketed Preferred Stock" means the Preferred Stock subject to the
Remarketing on the fifth Business Day prior to the Purchase Contract Settlement
Date; the term "Remarketing Procedures" means the procedures in connection with
the Remarketing of the Preferred Stock described in the Certificate of
Designations; and the term "Remarketing" means the remarketing of the Remarketed
Preferred Stock pursuant to the Remarketing Procedures.

     Section 1. APPOINTMENT AND OBLIGATIONS OF THE REMARKETING AGENT. (a) The
Company hereby appoints Lehman Brothers Inc., and Lehman Brothers Inc. hereby
accepts appointment, as exclusive remarketing agent (the "Remarketing Agent")

the holders thereof and (ii) performing such other duties as are assigned to the
Remarketing Agent in the Remarketing Procedures, all in accordance with and
pursuant to the Remarketing Procedures.

     (b) The Remarketing Agent agrees (i) to use commercially reasonable efforts
to remarket the Remarketed Preferred Stock tendered or deemed tendered to the

     (c) On the third Business Day immediately preceding the Purchase Contract
Settlement Date (the "Remarketing Date"), the Remarketing Agent shall use
commercially reasonable efforts to remarket, at a price equal to 100.50% of the
aggregate liquidation preference thereof, the Remarketed Preferred Stock
tendered or deemed tendered for purchase.

     (d) If, as a result of the efforts described in Section 1(b), the

annum that will enable it to remarket all Remarketed Preferred Stock tendered or
deemed tendered for Remarketing.

     (e) If none of the holders of Remarketed Preferred Stock elects to have
Remarketed Preferred Stock Remarketed in the Remarketing, the Remarketing Agent
shall, in its sole discretion, determine the rate that would have been
established had a Remarketing of all the Preferred Stock been held on the
Remarketing Date, and such rate shall be the Reset Rate.

     (f) If, by 4:00 p.m., New York City time, on the Remarketing Date, the
Remarketing Agent is unable to remarket all Remarketed Preferred Stock tendered
or deemed tendered for purchase, a failed Remarketing (the "Failed Remarketing")
shall be deemed to have occurred, and the Remarketing Agent shall so advise by
telephone the Depositary and the Company. If a Failed Remarketing occurs, the
Reset Rate will be equal to (i) the "AA" Composite Commercial Paper Rate on the
Remarketing Date, plus (ii) a spread as set forth in the Certificate of
Designations.

     (g) By approximately 4:30 p.m., New York City time, on the Remarketing
Date, provided that there has not been a Failed Remarketing, the Remarketing
Agent shall advise, by telephone (i) the Depositary and the Company of the Reset
Rate determined in the Remarketing and the number of shares of Remarketed
Preferred Stock sold in the Remarketing, (ii) each purchaser (or the Depositary

shares of Remarketed Preferred Stock purchased through the facilities of the
Depositary.

     (h) The Remarketing Agent shall remit (i) to the Collateral Agent proceeds
of the Remarketed Preferred Stock subject to the Pledge Agreement in an amount
equal to 100% of the aggregate liquidation preference of such Remarketed
Preferred Stock and (ii) to the Depositary Participant of the seller of
Remarketed Preferred Stock not subject to the Pledge Agreement proceeds of such
Remarketed Preferred Stock in an amount equal to 100% of the aggregate

     agreement or other agreement or instrument to which the Company or any of
     its subsidiaries is a party or by which the Company or any of its
     subsidiaries is bound or to which any of the properties or assets of the
     Company or any of its subsidiaries is subject, nor will such actions result

     or any of its subsidiaries or any statute or any order, rule or regulation
     of any court or governmental agency or body having jurisdiction over the
     Company or any of its subsidiaries or any of their respective properties or
     assets; and except for such consents, approvals, authorizations,
     registrations or qualifications as may be required under the Securities
     Act, the Exchange Act and applicable state securities laws in connection
     with the initial distribution of the Preferred Stock and the Remarketed
     Preferred Stock or the Remarketing, no consent, approval, authorization or
     order of, or filing or registration with, any such court or governmental
     agency or body is required for the Transactions.

          (o) There are no contracts, agreements or understandings between (i)
     the Company and (ii) any person granting such person the right to require
     the Company to file a registration statement under the Securities Act with

     securities registered pursuant to the Registration Statement or in any

<PAGE>
                                       7


     securities being registered pursuant to any other registration statement
     filed by the Company under the Securities Act.

          (p) Neither the Company nor any of its subsidiaries has sustained,
     since the date of the latest audited financial statements included or
     incorporated by reference in the Prospectus or in any Remarketing
     Materials, any 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, which
     could, individually or in the aggregate, reasonably be expected to have a
     material adverse effect on the general affairs, management, financial
     position, shareholders' equity or results of operations of the Company and
     its subsidiaries taken as a whole or upon the ability of the Company to
     perform its obligations under this Agreement (each, a "Material Adverse
     Effect"), otherwise than as set forth or contemplated in the Prospectus and
     in any Remarketing Materials; and, since such date, there has not been any
     material change in the consolidated share capital or long-term debt of the
     Company and its subsidiaries or the consolidated share capital or long-term
     debt of any Significant Subsidiary or any material adverse change, or any
     development involving a prospective material adverse change, in or
     affecting the general affairs, management, financial position,
     shareholders' equity or results of operations of the Company and its
     subsidiaries, otherwise than as set forth or contemplated in the Prospectus

          (q) The financial statements filed as part of the Registration
     Statement or incorporated by reference in the Prospectus or as presented in
     any Remarketing Materials 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 involved; and the supporting schedules included or
     incorporated by reference in the Prospectus or in any Remarketing Materials
     present fairly the information required to be stated therein.

          (r) Deloitte & Touche LLP, who have certified certain financial
     statements of the Company, whose report appears in the Prospectus or is
     incorporated by reference therein or in any Remarketing Materials and who
     have delivered the letter referred to in Section 5(g) hereof, are
     independent public accountants as required by the Securities Act and the
     Rules and Regulations.

     Prospectus or in any Remarketing Materials, except properties and assets
     that are leased or that are sold or otherwise disposed of in the ordinary
     course of business after the date of said balance sheet, subject to no
     mortgages, liens, charges or encumbrances of any kind whatsoever
     (collectively, the "Liens").

          (t) Other than as set forth or incorporated by reference 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
     or asset of the Company or any of its subsidiaries is the subject which
     could reasonably be expected individually or in the aggregate to have a
     Material Adverse Effect; and to the best of the Company's knowledge, no
     such proceedings are threatened or contemplated by governmental authorities
     or threatened by others. Neither the Company nor any of its subsidiaries is
     a party to any written agreement or memorandum of understanding with, or
     commitment letter or similar undertaking to, or subject to any order or
     directive issued by, or a recipient of any extraordinary supervisory letter
     from, or has adopted any board resolutions at the request of, any federal
     or state goverment agency or authority with responsibility for the
     supervision or regulation of depository institutions or their holding
     companies or the insurance of deposits, which in any such case materially
     restricts the conduct of its business or in any manner relates to its
     capital adequacy, its credit policies or its management, nor has the
     Company or any of its subisdiaries been advised by any such regulatory
     authority that it is contemplating issuing or requesting any such order,
     decree, written agreement, memorandum of understanding, extraordinary
     supervisory letter, commitment letter or similar undertakings or board
     resolutions.

          (u) The conditions for use of Form S-3, as set forth in the General
     Instructions thereto, have been satisfied.

          (v) There are no contracts or other documents which are required to be
     described in the Prospectus or filed as exhibits to the Registration
     Statement by the Securities Act or by the Rules and Regulations which have
     not been described in the Prospectus or filed as exhibits to the
     Registration Statement or incorporated therein by reference as permitted by
     the Rules and Regulations.

          (w) No filing with, or authorization, approval, consent, license,
     order, registration, qualification or decree of, any court or governmental
     authority or agency, including, without limitation, the OTS and the FDIC,
     is necessary or required for the due authorization, execution and delivery
     by the Company of this Agreement or for the performance by the Company of
     the Transactions, except such as have been already obtained or will have
     been obtained or made prior to the Closing Date (as defined in the
     Underwriting Agreement, dated August 4, 1999, between the Company and
     Lehman Brothers) or as may be required under the Securities Act or the
     Rules and Regulations or state securities laws.

          (x) None of the Company nor any Significant Subsidiary has any
     material contingent liability which is not disclosed in the Prospectus.

          (y) None of the Company nor any Significant Subsidiary (i) is in
     violation of its charter or by-laws or similar constitutive documents, (ii)
     is in default in any respect, and no event has occurred which, with notice
     or lapse of time or both, would constitute such a default, in the due
     performance or observance of any term, covenant or condition contained in
     any material indenture, mortgage, deed of trust, loan agreement or other
     agreement or instrument to which it is a party or by which it is bound or
     to which any of its properties or assets is subject, except where such
     defaults, individually or in the aggregate, could not reasonably be
     expected to have a Material Adverse Effect or (iii) is in violation in any
     material respect of any law, ordinance, governmental rule, regulation or
     court decree to which it or its properties or assets may be subject or has
     failed to obtain any material license, permit, certificate, franchise or
     other governmental authorization or permit necessary to the ownership of
     its properties or assets or to the conduct of its

<PAGE>
                                       9


          business, except where such violations or failures, individually or in
     the aggregate, could not reasonably be expected to have a Material Adverse
     Effect.

          (z) Neither the Company nor any subsidiary of the Company is an
     "investment company" within the meaning of such term under the Investment
     Company Act of 1940, as amended (the "1940 Act"), and the rules and
     regulations of the Commission thereunder.

          (aa) Each of the Company and each Significant Subsidiary has statutory
     authority, franchises and consents free from burdensome restrictions and
     adequate for the conduct of the business in which it is engaged.

          (bb) In the event the Company shall become either directly or
     indirectly a bank holding company for purposes of the Bank Holding Company
     Act of 1956, as amended (the "BHC Act"), and the rules and regulations of
     the Board of Governors of the Federal Reserve System thereunder (the "BHC
     Rules"), the current activities of the Company and its subsidiaries (as
     defined in the BHC Rules) would be activities permissible for a bank
     holding company under the BHC Act and the BHC Rules.

          (cc) The Prospectus accurately describes the existing limitations on
     the payment of dividends by Bank United on its shares of common stock held
     by the Company.

     3. FEES AND EXPENSES. (a) For the performance of its services as
Remarketing Agent hereunder, the Remarketing Agent shall retain on the Purchase

Agent); and (iv) all other costs and expenses incident to the performance of the
obligations of the Company hereunder.

     date of the Prospectus and for so long as the delivery of a prospectus is
     required in connection with the offering or sale of the Remarketed
     Securities; to advise the Remarketing Agent, promptly after it receives
     notice thereof, of the issuance by the Commission of any stop order or of

     Stock for offering or sale in any jurisdiction, of the initiation or

     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

                                       13



          subject to no material liability or disability by reason of the
          failure to be so qualified in any such jurisdiction.

               (iv) There are no preemptive or other rights to subscribe for or
          to purchase, nor any restriction upon the voting or transfer of the
          Preferred Stock or the Remarketed Preferred Stock pursuant to the
          Company's charter or by-laws or any agreement or other instrument
          known to such counsel.

               (v) To the best of such counsel's knowledge and other than as set
          forth in the Prospectus or in any Remarketing Materials, 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 or asset of
          the Company or any of its subsidiaries is subject which could
          reasonably be expected individually or in the aggregate to have a
          material adverse effect on the consolidated financial position,
          shareholders' equity or results of operations of the Company and its
          subsidiaries; and, to the best of such counsel's knowledge and other
          than as set forth in the Prospectus, no such proceedings are
          threatened or contemplated by governmental authorities or threatened
          by others.

               (vi) The Registration Statement was declared effective under the
          Securities Act, as of the date and time specified in such opinion, the
          Prospectus was filed with the Commission pursuant to the subparagraph
          of Rule 424(b) of the Rules and Regulations specified in such opinion
          on the date specified therein and, to the knowledge of such counsel,
          no stop order suspending the effectiveness of the Registration
          Statement has been issued and no proceeding for that purpose is
          pending or threatened by the Commission.

               (vii) The Registration Statement, as of its Effective Date, and
          the Prospectus, as of its date, and any further amendments or
          supplements thereto, as of their respective dates, made by the Company
          prior to the Purchase Contract Settlement Date (other than the
          financial statements, related schedules and other financial data
          contained therein, as to which such counsel need express no opinion)
          complied as to form in all material respects with the requirements of
          the Securities Act and the Rules and Regulations.

               (viii) The statements contained in the Prospectus under the
          captions "Description of the PIES", "Description of the Purchase
          Contracts", "Certain Provisions of the Purchase Contracts, the
          Purchase Contract Agreement and the Pledge Agreement" and "Description
          of the Preferred Stock" insofar as they purport to constitute
          summaries of certain terms of documents referred to therein,
          constitute accurate summaries of the terms of such documents in all
          material respects.

               (ix) The shares of Preferred Stock have been duly authorized


<PAGE>
                                       14





          by the Company and were duly and validly issued, fully paid and
          non-assessable.

               (x) This Agreement has been duly authorized, executed and
          delivered by the Company.

               (xi) The Purchase Contract Agreement has been duly authorized by
          the Company and, when duly executed by the proper officers of the
          Company (assuming due execution and delivery by the Purchase Contract
          Agent) and delivered by the Company, constitutes a valid and binding
          agreement of the Company enforceable against the Company in accordance
          with its terms, except as the enforcement thereof may be limited by
          the Bankruptcy Exceptions and an implied covenant of good faith and
          fair dealing.

               (xii) The Pledge Agreement has been duly authorized by the
          Company and, when duly executed by the proper officers of the Company
          (assuming due execution and delivery by the Purchase Contract Agent,
          the Securities Intermediary and the Collateral Agent) and delivered by
          the Company, constitutes a valid and binding agreement of the Company
          enforceable against the Company in accordance with its terms, except
          as the enforcement thereof may be limited by the Bankruptcy Exceptions
          and an implied covenant of good faith and fair dealing.

               (xiii) The Transactions will not conflict with or result 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 known to such counsel
          to which the Company or any of the Significant Subsidiaries is a party
          or by which the Company or any of the Significant Subsidiaries is
          bound or to which any of the properties or assets of the Company or
          any of the Significant Subsidiaries is subject, nor will such actions
          result in any violation of the provisions of the charter or by-laws of
          the Company or any of the Significant Subsidiaries or any statute,
          rule or regulation or any order known to such counsel of any court or
          governmental agency or body having jurisdiction over the Company or
          any of the Significant Subsidiaries or any of their properties or
          assets; and, except for the registration of the Preferred Stock and
          such consents, approvals, authorizations, registrations or
          qualifications as may be required under the Exchange Act and
          applicable state securities laws, no consent, approval, authorization
          or order of, or filing or registration with, any such court or
          governmental agency or body is required for the Transactions.

               (xiv) Neither the Company nor any of its subsidiaries is an
          "investment company" or an entity "controlled" by an "investment
          company" as such terms are defined in the 1940 Act.



<PAGE>
                                       15


               (xv) Based upon current law and the assumptions stated or
          referred to therein, the statements set forth in the Prospectus or in
          the Remarketing Materials under the caption "United States Federal
          Income Tax Consequences" insofar as they purport to constitute
          summaries of matters of United States federal tax laws and regulations
          or legal conclusions with respect thereto, constitute accurate
          summaries of the matters described therein in all material respects.

In rendering such opinion, such counsel may (i) state that its opinion is
limited to matters governed by the Federal laws of the United States of America
and the laws of the State of New York and the General Corporation Law of the
State of Delaware. Such counsel shall also advise the Remarketing Agent that
although such counsel is not passing upon and assumes no responsibility or
liability for the accuracy, completeness or fairness of the statements contained
in the documents incorporated by reference in the Prospectus or any further
amendment or supplement thereto made by the Company prior to such Remarketing
Date, they have no reason to believe that any of such documents (other than the
financial statements and related schedules therein, as to which such counsel
need express no opinion), when such documents became effective or were filed
with the Commission, as the case may be, contained, in the case of a
registration statement which became effective under the Securities Act, an
untrue statement of a material fact or omitted to state a material fact required
to be stated therein necessary to make the statements therein not misleading,
or, in the case of other documents which were filed under the Securities Act or
the Exchange Act with the Commission, an untrue statement of a material fact or
omitted to state a material fact necessary in order to make the statements
therein, in light of the circumstances under which they were made when such
documents were so filed, not misleading. Such counsel shall also advise the
Remarketing Agent that although such counsel is not passing upon and, except as
set forth in clauses (viii) and (xv) above, assumes no responsibility or
liability for the accuracy, completeness or fairness of the statements contained
in the Registration Statement, the Prospectus and the Remarketing Materials and
any further amendments and supplements thereto made by the Company prior to such
date, they have no reason to believe that, as of its effective date, the
Registration Statement or any further amendment thereto made by the Company
prior to such date (other than the financial statements and related schedules
therein, as to which such counsel need express no opinion) contained an untrue
statement of a material fact or 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 and the Remarketing Materials or any
further amendment or supplement thereto made by the Company prior to such
Remarketing Date (other than the financial statements and related schedules
therein, as to which such counsel need express no opinion) contained an untrue
statement of a material fact or omitted to state a material fact necessary to
make the statements therein, in light of the circumstances under which they were
made, not misleading or that, as of such Remarketing Date, either the Registra-
tion Statement, the Prospectus or the Remarketing Materials or any further
amendment or supplement thereto made by the Company prior to such Remarketing
Date (other than the financial statements and related schedules therein, as to
which such counsel need express no opinion) contains an untrue statement of a
material fact or omits to state a material fact
<PAGE>
                                       16

necessary to make the statements therein, in light of the circumstances under
which they were made, not misleading; and they do not know of any amendment to
the Registration Statement required to be filed or 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 Prospectus or the
Remarketing Materials or required to be described in the Registration Statement,
the Prospectus or the Remarketing Materials which were not filed or incorporated
by reference or described as required.

          (e) Counsel to the Purchase Contract Agent shall have furnished to the
     Remarketing Agent its written opinion, as counsel to the Purchase Contract
     Agent, addressed to the Remarketing Agent and dated the Remarketing Date,
     in form and substance satisfactory to the Remarketing Agent, to the effect
     that:

               (i) The Purchase Contract Agent is duly incorporated and is
          validly existing as a banking corporation in good standing under the
          laws of the jurisdiction of its incorporation with all necessary power
          and authority to execute, deliver and perform its obligations under
          the Purchase Contract Agreement and the Pledge Agreement.

               (ii) The execution, delivery and performance by the Purchase
          Contract Agent of the Purchase Contract Agreement and the Pledge
          Agreement and the authentication and delivery of the PIES have been
          duly authorized by all necessary corporate action on the part of the
          Purchase Contract Agent. The Purchase Contract Agreement and the
          Pledge Agreement have been duly executed and delivered by the Purchase
          Contract Agent and constitute the valid and binding agreements of the
          Purchase Contract Agent, enforceable against the Purchase Contract
          Agent in accordance with their terms, except as the enforcement
          thereof may be limited by the Bankruptcy Exceptions and an implied
          covenant of good faith and fair dealing.

               (iii) The execution, delivery and performance of the Purchase
          Contract Agreement and the Pledge Agreement by the Purchase Contract
          Agent does not conflict with or constitute a breach of the charter or
          by-laws of the Purchase Contract Agent.

               (iv) No consent, approval or authorization of, or registration
          with or notice to, any state or federal governmental authority or
          agency is required for the execution, delivery or performance by the
          Purchase Contract Agent of the Purchase Contract Agreement and the
          Pledge Agreement.

          (f) Counsel to the Collateral Agent shall have furnished to the
     Remarketing Agent its written opinion, as counsel to the Collateral Agent,
     and addressed to the Remarketing Agent and dated the Remarketing Date, in
     form and substance satisfactory to the Remarketing Agent, to the effect
     that:



<PAGE>
                                       17




               (i) The Collateral Agent is duly incorporated and is validly
          existing as a banking corporation in good standing under the laws of
          the jurisdiction of incorporation with all necessary power and
          authority to execute, deliver and perform its obligations under the
          Pledge Agreement.

               (ii) The execution, delivery and performance by the Collateral
          Agent of the Pledge Agreement in its capacity as Collateral Agent and
          securities intermediary have been duly authorized by all necessary
          corporate action on the part of the Collateral Agent. The Pledge
          Agreement has been duly executed and delivered by the Collateral Agent
          and constitutes the valid and binding agreement of the Collateral
          Agent, enforceable against the Collateral Agent in accordance with its
          terms, except as the enforcement thereof may be limited by the
          Bankruptcy Exception and an implied covenant of good faith and fair
          dealing.

               (iii) The execution, delivery and performance of the Pledge
          Agreement by the Collateral Agent in its capacity as Collateral Agent
          and securities intermediary does not conflict with or constitute a
          breach of the charter or by-laws of the Collateral Agent.

               (iv) No consent, approval or authorization of, or registration
          with or notice to, any state or Federal governmental authority or
          agency is required for the execution, delivery or performance by the
          Collateral Agent of the Pledge Agreement.

          (g) On the Remarketing Date, the Company shall have furnished to the
     Remarketing Agent a letter addressed to the Remarketing Agent and dated
     such date, in form and substance satisfactory to the Remarketing Agent, of
     Deloitte & Touche LLP, or such other firm of nationally recognized
     independent public accountants satisfactory to the Remarketing Agent,
     containing statements and information of the type ordinarily included in
     accountants' "comfort letters" with respect to certain financial
     information contained in the Prospectus and in the Remarketing Materials.

          (h) The Company shall have furnished to the Remarketing Agent a
     certificate, dated the Remarketing Date, of (A) the Company's Chairman of
     the Board and President, or its Executive Vice President and (B) its chief
     financial officer, stating that:

               (i) The representations, warranties and agreements of the Company
          in Section 2 are true and correct as of the Remarketing Date; the
          Company has complied with all its agreements contained herein; and the
          conditions contained in Section 5(a) have been fulfilled;

               (ii) (A) Neither the Company, the Bank nor any of the Company's
          other subsidiaries has sustained since the date of the latest audited
          financial statements included or incorporated by reference in the
          Prospectus or in the Remarketing Materials any loss or interference
          with its business from fire,


<PAGE>
                                       18


          explosion, flood or other calamity, whether or not covered by
          insurance, or from any labor dispute or court or governmental action,
          order or decree, which could, individually or in the aggregate,
          reasonably be expected to have a Material Adverse Effect, otherwise
          than as set forth or contemplated in the Prospectus or in the
          Remarketing Materials and (B) since the respective dates as of which
          information is given in the Prospectus or in the Remarketing
          Materials, there has not been any material change in the consolidated
          share capital or long-term debt of the Company and its subsidiaries
          (including, without limitation, the Bank) or the consolidated share
          capital or long-term debt of any Significant Subsidiary (including,
          without limitation, the Bank) or any change, or any development
          involving a prospective change, in or affecting the general affairs,
          management, financial position, shareholders' equity or results of
          operations of the Company and its subsidiaries, including without
          limitation the Bank (taken as a whole), otherwise than as set forth or
          contemplated in the Prospectus or the Remarketing Materials; and

               (iii) They have carefully examined the Registration Statement,
          the Prospectus and the Remarketing Materials and, in their opinion (A)
          the Registration Statement, as of its Effective Date, and the
          Prospectus and the Remarketing Materials, as of their respective
          dates, did not include any untrue statement of a material fact and did
          not omit to state any material fact required to be stated therein or
          necessary to make the statements therein not misleading, and (B) since
          such dates, no event has occurred which should have been set forth in
          a supplement or amendment to the Registration Statement, the
          Prospectus or the Remarketing Materials.

          (i) There shall not have been, since the date hereof or since the
     respective dates as of which information is given in the Final Prospectus,
     any material adverse change in the condition, financial or otherwise, or in
     the consolidated financial position, stockholders' equity, results of
     operations, business or prospects of the Company and its subsidiaries
     considered as one enterprise, whether or not arising in the ordinary course
     of business.

          (j) Without the prior written consent of the Remarketing Agent, the
     Certificate of Designations shall not have been amended in any manner, or
     otherwise contain any provision contained therein as of the date hereof
     that, in the opinion of the Remarketing Agent, materially changes the
     nature of the Remarketed Preferred Stock or the Remarketing Procedures.

          (k) Subsequent to the execution and delivery of this Agreement, (i) no
     downgrading shall have occurred in the rating accorded the Preferred Stock
     or any of the Company's or any Significant Subsidiary's (including, without
     limitation, the Bank) 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 Securities 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
     Preferred Stock or any


<PAGE>
                                       19



     of the Company's or any Significant Subsidiary's (including, without
     limitation, the Bank) debt securities.

          (l) Subsequent to the execution and delivery of this Agreement, there
     shall not have occurred any of the following: (i) trading in securities
     generally on the New York Stock Exchange or the American Stock Exchange or
     in the over-the-counter market, or trading in any securities of the Company
     on any exchange or in the over-the-counter market, shall have been
     suspended or minimum prices shall have been established on any such
     exchange or such market by the Commission, by such exchange or by any other
     regulatory body or governmental authority having jurisdiction, (ii) a
     banking moratorium shall have been declared by Federal or state
     authorities, (iii) the United States shall have become engaged in
     hostilities, there shall have been an escalation in hostilities involving
     the United States or there shall have been a declaration of a national
     emergency or war by the United States or (iv) there shall have occurred
     such a material adverse change in general economic, political or financial
     conditions (or the effect of international conditions on the financial
     markets in the United States shall be such) as to make it, in the judgment
     of the Remarketing Agent, impracticable or inadvisable to proceed with the
     Remarketing on the terms and in the manner contemplated in the Prospectus
     or in the Remarketing Materials.

     All opinions, letters, evidence and certificates mentioned above or
elsewhere in this Agreement shall be deemed to be in compliance with the
provisions hereof only if they are in form and substance reasonably satisfactory
to counsel for the Remarketing Agent.

     6. INDEMNIFICATION AND CONTRIBUTION. (a) The Company shall indemnify and
hold harmless the Remarketing Agent, its officers and employees and each person,
if any, who controls the Remarketing Agent within the meaning of the Securities
Act, from and against any loss, claim, damage or liability, joint or several, or
any action in respect thereof (including, but not limited to, any loss, claim,
damage, liability or action relating to purchases and sales of the Remarketed
Preferred Stock), to which the Remarketing Agent or that officer, employee or
controlling person may become subject, under the Securities Act or otherwise,
insofar as such loss, claim, damage, liability or action arises out of, or is
based upon, (i) any untrue statement or alleged untrue statement of a material
fact contained (A) in any Preliminary Prospectus, the Registration Statement,
the Prospectus or the Remarketing Materials or in any amendment or supplement
thereto, or (B) in any blue sky application or other document prepared or
executed by the Company (or based upon any written information furnished by the
Company) specifically for the purpose of qualifying any or all of the Remarketed
Preferred Stock under the securities laws of any state or other jurisdiction
(any such application, document or information being hereinafter called a "Blue
Sky Application"), or (ii) the omission or alleged omission to state in any
Preliminary Prospectus, the Registration Statement, the Prospectus or the
Remarketing Materials or in any amendment or supplement thereto, or in any Blue
Sky Application, any material fact required to be stated therein or necessary to
make the statements therein not misleading and shall reimburse the Remarketing
Agent and each such officer, employee and controlling person promptly upon
demand for any legal or other expenses reasonably incurred by the Remarketing
Agent or that officer, employee or controlling person in connection with


<PAGE>
                                       20


investigating or defending or preparing to defend against any such loss,
claim, damage, liability or action as such expenses are incurred; provided,
however, that the Company shall not be liable in any such case to the extent
that any such loss, claim, damage, liability or action arises out of, or
is based upon, any untrue statement or alleged untrue statement or omission or
alleged omission made in any Preliminary Prospectus, the Registration Statement,
the Prospectus or the Remarketing Materials or in any such amendment or
supplement, or in any Blue Sky Application in reliance upon and in conformity
with the written information furnished to the Company by or on behalf of the
Remarketing Agent specifically for inclusion therein and described in a letter
from the Remarketing Agent to the Company and provided further, that as to any
Preliminary Prospectus this indemnity agreement shall not inure to the benefit
of the Remarketing Agent, its officers or employees or any person controlling
the Remarketing Agent on account of any loss, claim, damage, liability or action
arising from the sale of the Remarketed Preferred Stock to any person by the
Remarketing Agent if the Remarketing Agent failed to send or give a copy of the
Prospectus, as the same may be amended or supplemented, to that person within
the time required by the Securities Act, and the untrue statement or alleged
untrue statement of a material fact or omission or alleged omission to state a
material fact in such Preliminary Prospectus was corrected in the Prospectus,
unless such failure resulted from non-compliance by the Company with Section
4(c). For purposes of the last proviso to the immediately preceding sentence,
the term "Prospectus" shall not be deemed to include the documents incorporated
therein by reference, and the Remarketing Agent shall not be obligated to send
or give any supplement or amendment to any document incorporated by reference in
any Preliminary Prospectus or the Prospectus to any person other than a person
to whom the Remarketing Agent had delivered such incorporated document or
documents in response to a written request therefor. The foregoing indemnity
agreement is in addition to any liability which the Company may otherwise have
to the Remarketing Agent or to any officer, employee or controlling person of
the Remarketing Agent.

     (b) The Remarketing Agent shall indemnify and hold harmless the Company,
its officers and employees, its directors and each person, if any, who controls
the Company within the meaning of the Securities Act, from and against any loss,
claim, damage or liability, joint or several, or any action in respect thereof,
to which the Company, any such director, officer or employee or any such
controlling person may become subject, under the Securities Act or otherwise,
insofar as such loss, claim, damage, liability or action arises out of, or is
based upon, (i) any untrue statement or alleged untrue statement of a material
fact contained (A) in any Preliminary Prospectus, the Registration Statement,
the Prospectus or the Remarketing Materials or in any amendment or supplement
thereto or (B) in any Blue Sky Application or (ii) the omission or alleged
omission to state in any Preliminary Prospectus, the Registration Statement, the
Prospectus or the Remarketing Materials or in any amendment or supplement
thereto, or in any Blue Sky Application, any material fact required to be stated
therein or necessary to make the statements therein not misleading, but in each
case only to the extent that the untrue statement or alleged untrue statement or
omission or alleged omission was made in reliance upon and in conformity with
the written information furnished to the Company by or on behalf of the
Remarketing Agent specifically for inclusion therein and described in a letter
from the Remarketing Agent to the Company and shall reimburse the Company and
any such director, officer or employee or such controlling person for any legal
or other expenses reasonably incurred by the Company or any such director or
officer or any such controlling person in
<PAGE>
                                       21




connection with investigating or defending or preparing to defend against
any such loss, claim, damage, liability or action as such expenses are
incurred. The foregoing indemnity agreement is in addition to any liability
which the Remarketing Agent may otherwise have to the Company or any such
director or officer or any such controlling person.

     (c) Promptly after receipt by an indemnified party under this Section 6 of
notice of any claim or the commencement of any action, the indemnified party
shall, if a claim in respect thereof is to be made against the indemnifying
party under this Section 6, notify the indemnifying party in writing of the
claim or the commencement of that action; provided, however, that the failure to
notify the indemnifying party shall not relieve it from any liability which it
may have under this Section 6 except to the extent it has been materially
prejudiced by such failure and, provided further, that the failure to notify the
indemnifying party shall not relieve it from any liability which it may have to
an indemnified party otherwise than under this Section 6. If any such claim or
action shall be brought against an indemnified party, and it shall notify the
indemnifying party thereof, the indemnifying party shall be entitled to
participate therein and, to the extent that it wishes, jointly with any other
similarly notified indemnifying party, to assume the defense thereof with
counsel satisfactory to the indemnified party. After notice from the
indemnifying party to the indemnified party of its election to assume the
defense of such claim or action, the indemnifying party shall not be liable to
the indemnified party under this Section 6 for any legal or other expenses
subsequently incurred by the indemnified party in connection with the defense
thereof other than reasonable costs of investigation; provided, however, that
the Remarketing Agent shall have the right to employ counsel to represent
jointly the Remarketing Agent and its officers, employees and controlling
persons who may be subject to liability arising out of any claim in respect of
which indemnity may be sought by the Remarketing Agent against the Company under
this Section 6 if, in the reasonable judgment of the Remarketing Agent, it is
advisable for the Remarketing Agent and those officers, employees and
controlling persons to be jointly represented by separate counsel, and in that
event the fees and expenses of such separate counsel shall be paid by the
Company. No indemnifying party shall (i) without the prior written consent of
the indemnified parties (which consent shall not be unreasonably withheld),
settle or compromise or consent to the entry of any judgment with respect to any
pending or threatened claim, action, suit or proceeding in respect of which
indemnification or contribution may be sought hereunder (whether or not the
indemnified parties are actual or potential parties to such claim or action)
unless such settlement, compromise or consent includes an unconditional release
of each indemnified party from all liability arising out of such claim, action,
suit or proceeding or (ii) be liable for any settlement of any such action
effected without its written consent (which consent shall not be unreasonably
withheld), but if settled with its written consent or if there be a final
judgment of the plaintiff in any such action, the indemnifying party agrees to
indemnify and hold harmless any indemnified party from and against any loss or
liability by reason of such settlement or judgment.

     (d) If the indemnification provided for in this Section 6 shall for any
reason be unavailable to or insufficient to hold harmless an indemnified party
under Section 6(a) or 6(b) in respect of any loss, claim, damage or liability,
or any action in respect thereof, referred to therein, then each indemnifying
party shall, in lieu of indemnifying such indemnified party, contribute to the
amount paid or payable by such indemnified party as a result of such loss,
claim, damage or


<PAGE>
                                       22



liability, or action in respect thereof, (i) in such proportion as shall be
appropriate to reflect the relative benefits received by the Company on the one
hand and the Remarketing Agent on the other hand from the Remarketing 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 on the one hand and the Remarketing Agent on the other with respect to
the statements or omissions which resulted in such loss, claim, damage or
liability, or action in respect thereof, as well as any other relevant
equitable considerations. The relative benefits received by the Company on
the one hand and the Remarketing Agent on the other with respect to
such offering shall be deemed to be in the same proportion as the total
liquidation preference of the Remarketed Securities less the fee paid
to the Remarketing Agent pursuant to Section 3(a) of this Agreement, on the one
hand, and the total fees received by the Remarketing Agent pursuant to such
Section 3(a), on the other hand, bear to the total liquidation preference of the
Remarketed Preferred Stock. The relative fault shall be determined by reference
to whether the untrue or alleged untrue statement of a material fact or omission
or alleged omission to state a material fact relates to information supplied by
the Company on the one hand or the Remarketing Agent on the other hand, the
intent of the parties and their relative knowledge, access to information and
opportunity to correct or prevent such statement or omission. The Company and
the Remarketing Agent agree that it would not be just and equitable if
contributions pursuant to this Section 6(d) were to be determined by pro rata
allocation or by any other method of allocation which does not take into account
the equitable considerations referred to herein. The amount paid or payable by
an indemnified party as a result of the loss, claim, damage or liability, or
action in respect thereof, referred to above in this Section 6(d) shall be
deemed to include, for purposes of this Section 6(d), 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 Section 6(d), the Remarketing Agent shall not be required to
contribute any amount in excess of the amount by which the fees received by it
under Section 3 exceed the amount of any damages which the Remarketing Agent has
otherwise paid or become liable to pay by reason of any 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 Securities Act)
shall be entitled to contribution from any person who was not guilty of such
fraudulent misrepresentation.

     7. RESIGNATION AND REMOVAL OF THE REMARKETING AGENT. The Remarketing Agent
may resign and be discharged from its duties and obligations hereunder, and the
Company may remove the Remarketing Agent, by giving 60 days' prior written
notice, in the case of a resignation, to the Company and the Depositary and, in
the case of a removal, the removed Remarketing Agent and the Depositary;
provided, however, that (i) the Company may not remove the Remarketing Agent
unless (A) the Remarketing Agent becomes involved as a debtor in a bankruptcy,
insolvency or similar proceeding, (B) the Remarketing Agent shall not be among
the 15 underwriters with the largest volume underwritten in dollars, on a lead
or co-managed basis, of U.S. domestic debt securities during the twelve-month
period ended as of the last calendar quarter preceding the Remarketing Date or
(C) the Remarketing Agent shall be subject to one or more legal restrictions
preventing the performance of its obligations hereunder and (ii) no such
resignation nor any such removal shall become effective until the Company shall
have appointed at least one nationally recognized broker-dealer as successor
Remarketing Agent

<PAGE>
                                       23




and such successor Remarketing Agent shall have entered into a remarketing
agreement with the Company in which it shall have agreed to conduct the
Remarketing in accordance with the Remarketing Procedures. In any such case,
the Company will use its reasonable efforts to appoint a successor Remarketing
Agent and enter into such a remarketing agreement with such person as soon as
reasonably practicable. The provisions of Sections 3 and 6 shall survive the
resignation or removal of any Remarketing Agent pursuant to
this Agreement.

     8. DEALING IN THE REMARKETED PREFERRED STOCK. The Remarketing Agent, when
acting as a Remarketing Agent or in its individual or any other capacity, may,
to the extent permitted by law, buy, sell, hold and deal in any shares of the
Remarketed Preferred Stock. The Remarketing Agent may exercise any vote or join
in any action which any beneficial owner of shares of Remarketed Preferred Stock
may be entitled to exercise or take pursuant to the Certificate of Designations
with like effect as if it did not act in any capacity hereunder. The Remarketing
Agent, in its individual capacity, either as principal or agent, may also engage
in or have an interest in any financial or other transaction with the Company as
freely as if it did not act in any capacity hereunder.

     9. REMARKETING AGENT'S PERFORMANCE; DUTY OF CARE. The duties and
obligations of the Remarketing Agent shall be determined solely by the express
provisions of this Agreement and the Certificate of Designations. No implied
covenants or obligations of or against the Remarketing Agent shall be read into
this Agreement or the Certificate of Designations. In the absence of bad faith
on the part of the Remarketing Agent, the Remarketing Agent may conclusively
rely upon any document furnished to it, which purports to conform to the
requirements of this Agreement or the Certificate of Designations as to the
truth of the statements expressed in any of such documents. The Remarketing
Agent shall be protected in acting upon any document or communication reasonably
believed by it to have been signed, presented or made by the proper party or
parties. The Remarketing Agent, acting under this Agreement, shall incur no
liability to the Company or to any holder of Remarketed Preferred Stock in its
individual capacity or as Remarketing Agent for any action or failure to act, on
its part in connection with a Remarketing or otherwise, except if such liability
is judicially determined to have resulted from the gross negligence or willful
misconduct on its part.

     10. TERMINATION. This Agreement shall terminate as to the Remarketing Agent
on the effective date of the resignation or removal of the Remarketing Agent
pursuant to Section 7. In addition, the obligations of the Remarketing Agent
hereunder may be terminated by it by notice given to the Company prior to 10:00
a.m., New York City time, on the Remarketing Date if, prior to that time, any of
the events described in Sections 5(i), (j), (k) or (l) shall have occurred.

     11. NOTICES. All statements, requests, notices and agreements hereunder
shall be in writing, and:

          (a) if to the Remarketing Agent, shall be delivered or sent by mail,

Agent and the person or persons, if any, who control the Remarketing Agent

agreement of the Remarketing Agent contained in Section 6(b) of this Agreement

                 [LETTERHEAD OF WACHTELL, LIPTON, ROSEN & KATZ]

Ladies and Gentlemen:

          Reference is made to the Registration Statements on Form S-3 (File
Nos. 333-75937 and 333-83797), as amended, filed with the Securities and
Exchange Commission (the "Registration Statement") in connection with the
registration under the Securities Act of 1933, as amended (the "Securities Act")
of up to $830,000,000 of Preferred Stock, Class A Common Stock, Depositary
Shares, Junior Subordinated Debt Securities, Guarantee, Stock Purchase Contracts
and Stock Purchase Units of Bank United Corp. (the "Company"), and Trust
Preferred Securities of Bank United Capital Trust (the foregoing securities
being collectively referred to herein as the "Securities"). You have requested
our opinion with respect to the following matters.

          In connection with the delivery of this opinion, we have examined
originals or copies of the Restated Certificate of Incorporation and the By-Laws
of the Company, the Registration Statement and the exhibits thereto, certain
resolutions adopted or to be adopted by the Board of Directors, the form of
certificates representing the securities offered and such other records,
agreements, instruments, certificates and other documents of public officials,
the Company and its officers and representatives, and have made such inquiries
of the Company and its officers and representatives, as we have deemed necessary
or appropriate in connection with

<PAGE>
Bank United Corp.

Page 2


the opinions set forth herein. We are familiar with the proceedings heretofore
taken, and with the additional proceedings proposed to be taken, by the Company
in connection with the authorization, registration, issuance and sale of the
Securities. With respect to certain factual matters, we have relied upon
representations from, or certificates of, officers of the Company. In making
such examination and rendering the opinions set forth below, we have assumed
without verification the genuineness of all signatures, the authenticity of all
documents submitted to us as originals, the authenticity of the originals of
such documents submitted to us as certified copies, the conformity to originals
of all documents submitted to us as copies, the authenticity of the originals of
such later documents, that all documents submitted to us as certified copies are
true and correct copies of such originals and the legal capacity of all
individuals executing such documents.

          Based on such examination and review, and subject to the foregoing, we
are of the opinion that, when any applicable state securities or Blue Sky laws
have been complied with, and upon issuance, delivery and payment therefor in the
manner contemplated by the Registration Statement, the Securities will be
validly issued, fully paid and non-assessable.

          We are members of the Bar of the State of New York, and we have not
considered, and we express no opinion as to, the laws of any jurisdiction other
than the laws of the United States of America, the State of New York and the
General Corporation Law of the State of Delaware.

          We consent to the inclusion of this opinion as an exhibit to the
Registration Statement and to the reference to our firm in the prospectus that
is a part of the Registration Statement, and in any supplements thereto. In
giving such consent, we do not hereby admit that we are in the category of
persons whose consent is required under Section 7 of the Securities Act.

                                     Very truly yours,
