ITEM 15.  INDEMNIFICATION OF DIRECTORS AND OFFICERS.
 
     (a) The Tennessee Business Corporation Act (the "TBCA") provides that a
corporation may indemnify any of its directors against liability incurred in
connection with a proceeding if (i) the director acted in good faith, (ii) in
the case of conduct in his or her official capacity with the corporation, the
director reasonably believed such conduct was in the corporation's best
interest, (iii) in all other cases, the director reasonably believed that his or
her conduct was not opposed to the best interest of the corporation, and (iv) in
connection with any criminal proceeding, the director had no reasonable cause to
believe that his or her conduct was unlawful. In actions brought by or in the
right of the corporation, however, the TBCA provides that no indemnification may
be made if the director was adjudged to be liable to the corporation. In cases
where the director is wholly successful, on the merits or otherwise, in the
defense of any proceeding instigated because of his or her status as a director
of a corporation, the TBCA mandates that the corporation indemnify the director
against reasonable expenses incurred in the proceeding. The TBCA also provides
that in connection with any proceeding charging improper benefit to a director,
no indemnification may be made if such director is adjudged liable on the basis
that personal benefit was improperly received. Notwithstanding the foregoing,
the TBCA provides that a court of competent jurisdiction, upon application, may
order that a director be indemnified for reasonable expense if, in consideration
of all relevant circumstances, the court determines that such individual is
fairly and reasonably entitled to indemnification, whether or not the standard
of conduct set forth above was met.
 
     (b) Article Eleven of the Amended and Restated Charter of the Registrant
sets forth the extent to which officers or directors of the Registrant may be
insured or indemnified against any liabilities which they may incur. The general
effect of such provision is that any person made a party to any action, suit or
proceeding by reason of the fact that he or she is or was a director or officer
of the Registrant will be indemnified by the Registrant against expenses
(including attorney's fees), judgments, fines, and amounts paid in settlement
actually and reasonably incurred by him or her in connection with such action,
suit or proceeding, to the fullest extent permitted under the laws of the State
of Tennessee. In addition, such provision provides that, in the Registrant's
sole discretion, the Registrant may indemnify employees or agents against such
expenses, judgments, fines, and amounts paid in settlement.
 
     (c) The Company maintains a policy of directors' and officers' insurance
that would in certain instances provide the funds necessary for the Registrant
to meet its obligations under its Amended and Restated Charter.

     (d) Reference is also made to Section 8 of the Underwriting Agreement filed
as Exhibit 1 hereto, which provides for indemnification by the Underwriters of
the Company and certain officers, directors, and controlling persons against
certain liabilities.

ITEM 17.  UNDERTAKINGS.
 
     The undersigned Registrant hereby undertakes:
 
          1. Insofar as indemnification for liabilities arising under the
     Securities Act may be permitted to directors, officers, and controlling
     persons of the Registrant pursuant to the foregoing provisions, or
     otherwise, that the Registrant has been advised that in the opinion of the
     Commission such indemnification is against public policy as expressed in
     the Securities Act and is, therefore, unenforceable. In the event that a
     claim for indemnification against such liabilities (other than the payment
     by the Registrant of expenses incurred or paid by a director, officer, or
     controlling person of the Registrant in the successful defense of any
     action, suit, or proceeding) is asserted against the Registrant by such
     director, officer, or
                                      II-2
<PAGE>   4
 
     controlling person in connection with the securities being registered, the
     Registrant will, unless in the opinion of its counsel the matter has been
     settled by controlling precedent, submit to a court of appropriate
     jurisdiction the question whether such indemnification by it is against
     public policy as expressed in the Securities Act and will be governed by
     the final adjudication of such issue.
 
          2. For purposes of determining any liability under the Securities Act,
     that each filing of the Registrant's annual report pursuant to Section
     13(a) or Section 15(d) of the Exchange Act (and, where applicable, each
     filing of an employee benefit plan's annual report pursuant to Section
     15(d) of the Exchange Act) that is incorporated by reference in the
     Registration Statement shall be deemed to be a new registration statement
     relating to the securities offered therein, and the offering of such
     securities at that time shall be deemed to be the initial bona fide
     offering thereof.
 
          3. For purposes of determining any liability under the Securities Act,
     the information omitted from the form of prospectus filed as part of this
     Registration Statement in reliance upon Rule 430A and contained in a form
     of prospectus filed by the Registrant pursuant to Rule 424(b)(1) or (4) or
     497(h) under the Securities Act shall be deemed to be part of this
     Registration Statement as of the time it was declared effective.
 
          4. For the purpose of determining any liability under the Securities
     Act, each post-effective amendment that contains a form of prospectus shall
     be deemed to be a new registration statement relating to the securities
     offered therein, and the offering of such securities at that time shall be
     deemed to be the initial bona fide offering thereof.

certifies that it has reasonable grounds to believe that it meets all of the
requirements for filing on Form S-3 and has duly caused this amendment to the
Registration Statement to be signed on its behalf by the undersigned, thereunto
duly authorized, in the City of Nashville, State of Tennessee, on March 17, 
1998.

Ladies and Gentlemen:

         Central Parking Finance Trust, a statutory business trust created under
the laws of the State of Delaware (the "Trust"), and Central Parking
Corporation, a Tennessee corporation (the "Company"), as depositor of the Trust
and as guarantor, propose, subject to the terms and conditions stated herein,
that the Trust issue and sell to the Initial Purchasers named in Schedule I
hereto (the "Initial Purchasers"), for whom you are acting as the
representatives (the "Representatives") an aggregate of 4,000,000 (the "Firm

400,000 (the "Optional Securities"), of 5 1/4% Convertible Trust Issued
Preferred Securities (liquidation amount $25 per preferred security),
representing undivided beneficial interests in the assets of the Trust,
guaranteed on a subordinated basis by the Company as to the payment of
distributions, and as to payments on liquidation or redemption, to the extent

Chase Bank of Texas, National Association, as trustee (the "Guarantee Trustee")
and convertible into common stock, $.01 par value per share ("Company Common
Stock"), of the Company. The Firm Securities and the Optional Securities that
the Initial Purchasers elect to purchase pursuant to Section 2 hereof are
referred to collectively as the "Preferred Securities." The Trust is to
purchase, with the proceeds of the sale of the Preferred Securities and up to
123,711 (or 136,082 assuming full exercise by the Initial Purchasers of the
over-allotment option described herein) of its Common Securities (liquidation

Debentures") of the Company, to be issued pursuant to an Indenture (the
"Indenture") between the Company and Chase Bank of Texas, National Association,
as trustee (the "Indenture Trustee").

         The Company will be the holder of 100% of the Common Securities. The
Trust will be subject to the terms of an Amended and Restated Trust Agreement
(the "Trust Agreement"), among the Company, as Depositor, Chase Bank of Texas,
National Association, as Property Trustee ("Property Trustee"), Chase Manhattan
Bank Delaware, as Delaware Trustee (the "Delaware Trustee") and three individual
trustees who are employees or officers of or affiliated with the Company (the
"Administrative Trustees"), and the holders from time to time, of undivided
beneficial interests in the assets of the Trust. The Property Trustee, the
Delaware Trustee and the Administrative Trustees are collectively referred to
herein as the "Trustees." The Company and the Trust will also enter into a
Registration Rights Agreement (the "Registration Rights Agreement") among the
Company, the Trust and the Initial Purchasers, which shall set forth the
obligations of the Company to file a Shelf Registration Statement (as defined in
the Registration Rights Agreement) in respect of the Preferred Securities, the
Guarantee, the Convertible Debentures and the Company Common Stock issuable upon
conversion of the Convertible Debentures and the Preferred Securities.

         1. Each of the Trust and the Company represents and warrants to, and
agrees with, each of the Initial Purchasers that:

                  (a) A preliminary offering circular, dated February 20, 1998
         (the "Preliminary Offering Circular") and an offering circular, dated
         March 13, 1998 (the "Offering Circular"), and the Company's Annual
         Report on Form 10-K for the fiscal year ended September 30, 1997, the
         Company's Quarterly Report on Form 10-Q for the quarter ended December
         31, 1997, the Company's Current Reports on Form 8-K filed February 17
         and 20, 1998, which are incorporated by reference therein, have been
         prepared in connection with the offering of the Preferred Securities,
         the Convertible Debentures, the Guarantee and the Company Common Stock
         issuable upon the conversion of the Preferred Securities and the
         Convertible Debentures. Any reference to the Preliminary Offering
         Circular or the Offering Circular shall be deemed to refer to and
         include the Company's most recent Annual Report on Form 10-K and all
         subsequent documents filed by the Company with the Securities and
         Exchange Commission (the "Commission") pursuant to Section 13(a), 13(c)
         or 15(d) of the Securities Exchange Act of 1934, as amended (the
         "Exchange Act"), on or prior to the date of the Preliminary Offering
         Circular or the Offering Circular, as the case may be, and any
         reference to the Preliminary Offering Circular or the Offering
         Circular, as the case may be, as amended or supplemented, as of any
         specified date, shall be deemed to include (i) any documents filed with
         the Commission pursuant to Section 13(a), 13(c) or 15(d) of the
         Exchange Act after the date of the Preliminary Offering Circular or the
         Offering Circular, as the case may be, and prior to such specified date
         and (ii) any Additional Issuer Information (as defined in Section 4(g))
         furnished by the Company prior to the completion of the distribution of
         the Trust Securities; and all documents filed under the Exchange Act
         and so deemed to be included in the Preliminary Offering Circular or

         Exchange Act Reports, when they were or are filed with the Commission,
         conformed or will conform in all material respects to the applicable
         requirements of the Exchange Act and the applicable rules and
         regulations of the Commission thereunder. The Preliminary Offering
         Circular or the Offering Circular and any amendments or supplements
         thereto and the Exchange Act Reports did not and will not, as of their
         respective dates, contain an untrue statement of a material fact or
         omit to state a material fact necessary in order to make the statements
         therein, in the light of the circumstances under which they were made,
         not misleading; provided, however, that this representation and
         warranty shall not apply to any statements or omissions made in
         reliance upon and in conformity with information furnished in writing
         to the Trust or the Company by any Initial Purchaser expressly for use
         therein (it being understood that the only information so provided is
         the information included in the last paragraph on the cover page, the
         fifth paragraph on page three and in the first, second, fourth and
         fourteenth paragraphs under the caption "Plan of Distribution" in the

         herein, the term "subsidiary" includes but is not limited to Central
         Parking System Realty, Inc., Square Industries, Inc., Diplomat Parking
         Corporation, Civic Parking, LLC and Kinney System Holding Corp.

         standing under the laws of its jurisdiction of incorporation, with full
         power and authority (corporate and other, as the case may be) to own
         its properties and conduct its business as now conducted, except where
         the failure to be in good standing would not have a material adverse
         effect on the Company and its subsidiaries taken as a whole; and the
         Company and each subsidiary is duly qualified or authorized to do
         business and is in good standing in all jurisdictions wherein the
         nature of its business or the character of property owned or leased may
         require it to be qualified or authorized to do business, except for
         jurisdictions in which the failure to so qualify would not have a
         material adverse effect on the Company and its subsidiaries, taken as a
         whole;

                  (c) The Trust has been duly created and is validly existing as
         a statutory business trust in good standing under the Business Trust
         Act of the State of Delaware (the "Delaware Business Trust Act") with
         the trust power and authority to own property and conduct its business
         as described in the Offering Circular, and has conducted and will
         conduct no business other than the transactions contemplated by this
         Agreement and described in the Offering Circular; the Trust is not a
         party to or bound by any agreement or instrument other than this
         Agreement, the Trust Agreement and the agreements and instruments
         contemplated by the Trust Agreement and described in the Offering
         Circular; based on expected operations and current law, the Trust is
         not and will not be classified as an association taxable as a
         corporation for United States federal income tax purposes; and the
         Trust is not a party to or subject to any action, suit or proceeding of
         any nature;

                  (d) The Preferred Securities have been duly and validly
         authorized by the Trust, and, when issued and delivered to the Initial
         Purchasers against payment therefor as provided


                                       3

         herein, will be duly and validly issued and, subject to the terms of
         the Trust Agreement, fully paid and non-assessable undivided beneficial
         interests in the assets of the Trust and will conform to the

         Preferred Securities is not subject to preemptive or other similar
         rights; the Preferred Securities will have the rights set forth in the
         Trust Agreement, and the terms of the Preferred Securities are valid
         and binding on the Trust; the holders of the Preferred Securities (the
         "Securityholders") will be entitled to the same limitation of personal
         liability extended to stockholders of private corporations for profit
         organized under the General Corporation Law of the State of Delaware;

                  (e) The Common Securities have been duly and validly
         authorized by the Trust and upon delivery by the Trust to the Company
         against payment therefor as described in the Offering Circular, will be
         duly and validly issued undivided beneficial interests in the assets of
         the Trust and will conform to the description thereof contained in the
         Offering Circular; the issuance of the Common Securities is not subject
         to preemptive or other similar rights; and at the First Closing Date
         (as defined in Section 2(c) hereof), all of the issued and outstanding
         Common Securities of the Trust will be directly owned by the Company
         free and clear of any Lien (as defined below); and the Trust Securities
         are the only interests authorized to be issued by the Trust;

                  (f) This Agreement has been duly authorized and validly
         executed and delivered by the Company and the Trust and constitutes a
         valid and legally binding agreement of each of the Company and the
         Trust, enforceable against the Company and the Trust in accordance with
         its terms (assuming the due execution and delivery hereof by the
         Initial Purchasers), except to the extent that (A) enforcement thereof
         may be limited by (1) bankruptcy, insolvency, reorganization,
         moratorium, fraudulent conveyance or other similar laws now or
         hereafter in effect relating to the rights of creditors generally and
         (2) general principles of equity (regardless of whether enforceability
         is considered in a proceeding at law or in equity), and (B) the
         enforceability of indemnification and contribution provisions may be
         limited by federal and state securities laws and the policies
         underlying such laws.

                  (g) The Guarantee, the Convertible Debentures, the Trust
         Agreement and the Indenture (collectively, the "Guarantor Agreements")
         have each been duly authorized and, when executed and delivered by the
         Company, will constitute valid and legally binding obligations of the
         Company, enforceable in accordance with their respective terms, except
         to the extent (A) that enforcement thereof may be limited by (1)
         bankruptcy, insolvency, reorganization, moratorium, fraudulent
         conveyance or other similar laws now or hereafter in effect relating to
         the rights of creditors generally, and (2) general principles of equity
         (regardless of whether enforceability is considered in a proceeding at
         law or in equity); (B) with respect to the Indenture, the waiver
         contained in Section 515 of the Indenture may be deemed unenforceable
         and (C) with respect to the Indenture, the enforceability, under
         certain circumstances, of provisions imposing a payment obligation if
         the Company is unable to

         comply timely with its registration obligations under the Registration
         Rights Agreement may be limited by applicable law;

                  (h) The Convertible Debentures are entitled to the benefits
         provided by the Indenture; each of the Guarantor Agreements will
         conform to the descriptions thereof in the Offering Circular and will
         be in substantially the form previously delivered to you;

                  (i) The Registration Rights Agreement has been duly authorized
         and, when executed and delivered by each of the Trust and the Company,
         will constitute the valid and legally binding obligations of each of
         the Trust and the Company, enforceable in accordance with its
         respective terms, except to the extent that (A) enforcement thereof may
         be limited by (1) bankruptcy, insolvency, reorganization, moratorium,
         fraudulent conveyance or other similar laws now or hereafter in effect
         relating to the rights of creditors generally, and (2) general
         principles of equity (regardless of whether enforceability is
         considered in a proceeding at law or in equity), (B) the enforceability
         of indemnification and contribution provisions may be limited by
         federal and state securities laws and the policies underlying such laws
         and (C) the enforceability, under certain circumstances, of provisions
         imposing a payment obligation if the Company is unable to comply timely
         with its registration obligations under the Registration Rights
         Agreement may be limited by applicable law.

                  (j) The documents that are incorporated by reference in any
         Preliminary Offering Circular and Offering Circular or from which
         information is so incorporated by reference, when they become effective
         or were filed with the Commission, as the case may be, complied in all
         material respects with the requirements of the Securities Act of 1933,
         as amended (the "Securities Act") or the Exchange Act, as applicable,
         and the rules and regulations of the Commission thereunder (the "Rules
         and Regulations").

                  (k) The Company has full legal right, power and authority to
         authorize the offering of the Convertible Debentures, the Guarantee and
         the Company Common Stock issuable upon the conversion of the Preferred
         Securities and the Convertible Debentures, to execute, deliver and

         Trust, will not result in a breach or violation of, or conflict with,
         any of the terms and provisions of, or constitute a default by the
         Company under the Amended and Restated Charter or bylaws of the
         Company. The Company is not in violation of its Amended and Restated
         Charter or bylaws or any law, administrative rule, or regulation or
         arbitrator's or administrative or court decree, judgment or order or in
         violation or default (there being no existing state of facts which with
         notice or lapse of time or both would constitute a default) in the
         performance or observance of any Lien (as defined below) other than
         violations and defaults which could not reasonably be expected to have
         a material adverse effect on the business condition (financial or
         otherwise), prospects, net worth, or results of operations of the
         Company and its subsidiaries, taken as a whole.

                  (n) The execution, delivery and performance of this Agreement,
         the Registration Rights Agreement and the Guarantor Agreements by the
         Company and the Trust, to the extent the Trust is a party to such
         agreement, and the consummation of the transactions contemplated hereby
         and thereby, will not (1) conflict with or result in a breach or
         violation of the Trust Agreement or any of the terms or provisions
         thereof, or (2) conflict with or result in a breach or violation of any
         of the terms or provisions of, or constitute a default or cause an
         acceleration of any obligation under or result in the imposition or
         creation of (or the obligation to create or impose) any security
         interest, mortgage, pledge, claim, lien or other encumbrances (each, a
         "Lien") with respect to, any bond, note, debenture or other evidence of
         indebtedness or any indenture, mortgage, deed of trust, loan agreement
         or other agreement or instrument to which the Company or the Trust is a
         party or by which they are bound, or to which any of the property or
         assets of the Company or the Trust is or may be subject, or (3)
         contravene any order of any court or governmental agency or body having
         jurisdiction over the Company or the Trust or any of their properties,
         or violate or conflict with any statute, rule or regulation or
         administrative or court decree applicable to the Company or the Trust,
         or any of their properties;

                  (o) The capitalization of the Company as of December 31, 1997
         is as set forth under the caption "Capitalization" in the Offering
         Circular, and the Company's capital stock, including the Company Common

                                       6

         Debentures have been duly and validly authorized and reserved for
         issuance and, when issued and delivered in accordance with the
         provisions of the Preferred Securities and the Indenture, will be duly
         and validly issued, fully paid and nonassessable and will conform to
         the descriptions thereof in the Offering Circular; the issuance of the
         Company Common Stock upon the conversion of the Preferred Securities
         and the Convertible Debentures will not be subject to preemptive or
         other similar rights;

                  (p) As of the date hereof, except as set forth on Schedule II
         hereto, all of the outstanding shares of capital stock or equity
         interests of the Company's subsidiaries have been duly and validly
         authorized and issued and are fully paid and nonassessable and all such
         shares and partnership interests are owned by the Company directly or
         indirectly through another subsidiary, free and clear of all liens,
         claims, encumbrances, security interests, restrictions, shareholder
         agreements, voting trusts or other claims of third parties. There are
         no preemptive rights or other rights to subscribe for or purchase, or
         any restriction upon the transfer of, any shares of capital stock of
         the Company's subsidiaries pursuant to any subsidiary's charter,
         bylaws, or other governing documents or any agreement or other
         instruments to which such subsidiary is a party.

                  (q) All offers and sales of the Company's securities prior to
         the date hereof were at all relevant times duly registered or the
         subject of an available exemption from the registration requirements of
         the Securities Act and the applicable state securities or Blue Sky
         laws.

                  (r) The consolidated financial statements and the related
         notes of the Company included or incorporated by reference in the
         Offering Circular present fairly the financial position, results of
         operations, and changes in financial position and cash flow of the
         Company at the dates and for the periods to which they relate and have
         been prepared in accordance with generally accepted accounting
         principles applied on a consistent basis throughout the periods
         indicated. The unaudited pro forma financial statements included or
         incorporated by reference in the Offering Circular comply in all
         material respects with the applicable accounting requirements of
         Article 11 of Regulation S-X promulgated by the Commission, and the pro
         forma adjustments have been applied properly to the historical
         financial statements. The other financial and statistical data included
         or incorporated by reference in the Offering Circular fairly presents
         the information set forth therein on the basis stated in the Offering
         Circular. KPMG Peat Marwick LLP, whose report is incorporated by

                  (s) Subsequent to the respective dates as of which information

         neither the Company nor the Trust have sustained any material loss or
         interference with their business or properties from fire, flood,
         hurricane, earthquake, accident or other calamity, whether or not
         covered by insurance, or from any labor dispute or any court or
         governmental action, order or decree, or become a

         party to or the subject of any litigation which is material to the
         Company or the Trust, nor shall there have been any material adverse
         change, or any development involving a prospective material adverse
         change, in the business, properties, key personnel, capitalization, net
         worth, results of operations or condition (financial or other) of the
         Company or the Trust, except in each case as described in or
         contemplated by the Offering Circular.

                  (t) There is not pending, or to the knowledge of the Company
         threatened, any action, suit, proceeding, inquiry, or investigation, to
         which the Company or any of its subsidiaries or any of the Company's
         officers or directors is a party, or to which the property of the
         Company or any of its subsidiaries is subject, before or brought by any
         court or governmental agency or body, wherein an unfavorable decision,
         ruling, or finding could prevent or materially hinder the consummation
         of this Agreement or could have a material adverse effect on the
         business condition (financial or otherwise), prospects, net worth, or
         results of operations of the Company and its subsidiaries, taken as a
         whole.

                  (u) Except as described in the Offering Circular, the Company
         and its subsidiaries have good and marketable title to all real and
         material personal property owned by them, free and clear of all liens,
         charges, encumbrances, or defects except those reflected in the
         financial statements herein above described. The real and personal
         property and buildings referred to in the Offering Circular which are
         leased from others by the Company or its subsidiaries are held under
         valid, subsisting and enforceable leases. The Company and its
         subsidiaries own or lease all such properties as are necessary to their
         operations as now conducted.

                  (v) The Company maintains a system of internal accounting
         controls sufficient to provide reasonable assurances that (i)
         transactions are executed in accordance with management's general or
         specific authorization; (ii) transactions are recorded as necessary to
         permit preparation of financial statements in conformity with generally
         accepted accounting principles and to maintain accountability for
         assets; (iii) access to assets is permitted only in accordance with
         management's general or specific authorization; and (iv) the recorded
         accountability for assets is compared with existing assets at
         reasonable intervals and appropriate action is taken with respect to
         any differences.

                  (w) The Company and each of its subsidiaries have filed all
         federal, state, and local income, excise, and franchise tax returns
         required to be filed through the date hereof and have paid all taxes
         shown as due therefrom; and there is no tax deficiency that has been,
         nor does the Company or any of its subsidiaries have knowledge of any
         tax deficiency which is likely to be asserted against the Company or
         any of its subsidiaries, which if determined adversely could materially
         and adversely affect the earnings, assets, affairs, business prospects,
         or condition (financial or otherwise) of the Company and its
         subsidiaries, taken as a whole.

         businesses in conformity in all material respects with all applicable
         statutes, common laws, ordinances, decrees, orders, rules, and
         regulations of governmental bodies. The Company and each of its
         subsidiaries have all material licenses, approvals, or consents to
         operate their businesses in all locations in which such businesses are
         currently being operated, and neither the Company nor any of its
         subsidiaries is aware of any existing or imminent matter that may
         materially adversely impact any of their operations or business
         prospects other than as specifically disclosed in the Offering
         Circular. No director, officer, or to the Company's knowledge, agent or
         employee of the Company or any of its subsidiaries, any other person
         associated with or acting for or on behalf of the Company or any of its
         subsidiaries, has directly or indirectly made any contribution, gift,
         bribe, rebate, payoff, influence payment, kickback, or other payment to

         property, or services (i) to obtain favorable treatment in securing
         business, (ii) to pay for favorable treatment for business obtained, or

         to file with the applicable regulatory authorities any statement,
         report, information, or form required by any applicable law,
         regulation, or order where the failure to file the same would have a
         material adverse effect on the Company and its subsidiaries, taken as a
         whole, or on their respective abilities to conduct business in any
         state; all such filings or submissions were in material compliance with
         applicable laws when filed and no deficiencies have been asserted by
         any regulatory commission, agency or authority with respect to such
         filings or submissions. Neither the Company nor any of its subsidiaries
         has failed to maintain in full force and effect any material license or

         businesses, or received any notification that any revocation or
         limitation thereof is threatened or pending, and, except as disclosed
         in the Offering Circular, there is not pending any change under any
         law, regulation, license or permit which could materially adversely
         affect any of their respective businesses, operations, properties or
         prospects. Neither the Company nor any of its subsidiaries has received
         any notice of violation of or been threatened with a charge of
         violating and are not, to the best of their knowledge, under
         investigation with respect to a possible violation of any provision of
         any law, regulation, or order.

                  (z) No labor dispute exists with the Company's or any of its
         subsidiaries' employees or is imminent which could materially adversely
         affect the Company. Neither the Company nor any of its subsidiaries is

         affairs, management, business affairs, or business prospects of the
         Company and its subsidiaries, taken as a whole.

                  (aa) The Company owns or possesses, or can acquire on
         reasonable terms, the patents, licenses, copyrights, trademarks,
         service marks and trade names presently employed by it in connection
         with the businesses now operated by it, and neither the Company nor any
         of its subsidiaries has received any notice of infringement of or
         conflict with asserted rights 



                                       9

         of others with respect to any of the foregoing which, alone or in the
         aggregate, if the subject of an unfavorable decision, ruling or
         finding, would result in any material adverse change in the condition,
         financial or otherwise, or in the earnings, business affairs, or
         business prospects of the Company and its subsidiaries, taken as a
         whole.

                  (bb) Neither the Company nor any of the directors, officers,
         or to the Company's knowledge, employees or agents of the Company, have
         taken and will not take, directly or indirectly, any action designed to
         cause or result in, or which has constituted or which might be expected
         to constitute, stabilization or manipulation of the price of any
         security of the Company in connection with the offering, the sale or
         resale of the of the Preferred Securities or the Company Common Stock
         issuable upon exercise or conversion of Preferred Securities and the
         Convertible Debentures.

         manufacture, refinement, transportation, handling or treatment of
         hazardous substances by the Company or any of its subsidiaries (or, to
         the knowledge of the Company, any of its or their predecessors in
         interest) at, upon or from any of the property now or previously owned
         or leased by the Company or any of its subsidiaries in violation of any
         applicable law, ordinance, rule, regulation, order, judgment, decree or
         permit or which could reasonably be expected to require remedial action
         under any applicable law, ordinance, rule, regulation, order, judgment,
         decree or permit, except for any violation or remedial action which
         could not be reasonably likely to have, singularly or in the aggregate
         with all such violations and remedial actions, a material adverse
         effect on the business, condition (financial or otherwise), prospects,
         properties, net worth or results of operations of the Company and its
         subsidiaries, taken as a whole; there has been no material spill,
         discharge, leak, emission, injection, escape, dumping or release of any
         kind onto such property or of any hazardous substances due to or caused
         by the Company or any of its subsidiaries or with respect to which the
         Company or any of its subsidiaries had knowledge, except for any such
         spill, discharge, leak, emission, injection, escape, dumping or release
         which would not be reasonably likely to have, singularly or in the
         aggregate with all such spills, discharges, leaks, emissions,
         injections, escapes, dumpings or releases, a material adverse effect on
         the business, condition (financial or otherwise), prospects,
         properties, net worth or results of operations of the Company and its
         subsidiaries, taken as a whole; and the term "hazardous substances"
         shall have the meaning specified in any applicable local, state,
         federal and foreign laws or regulations with respect to environmental
         protection.

                  (dd) The Company and its subsidiaries are insured by insurers
         of recognized financial responsibility against such losses and risks
         and in such amounts as management believes is appropriate to the
         business of the Company and its subsidiaries; all such policies of
         insurance insuring the Company and its subsidiaries or their respective
         businesses, assets, employees, officers and directors are in full force
         and effect; the Company and its subsidiaries are in compliance with the
         terms of such policies and instruments in all material respects; and

<PAGE>   11

         policy or instrument as to which any insurance company is denying
         liability or defending under a reservation of rights clause.

                  (ee) The Company is not, and will not become as a result of
         the offering and sale of the Trust Securities and the Company Common
         Stock issuable upon the conversion of the Preferred Securities and
         Convertible Debentures, an "investment company" or a company
         "controlled" by an "investment company" within the meaning of the
         Investment Company Act of 1940. The Trust is not required to be
         registered under the Investment Company Act.

                  (ff) None of the transactions contemplated by this Agreement
         (including, without limitation, the use of the proceeds from the sale
         of the Preferred Securities) will violate or result in a violation of
         Section 7 of the Exchange Act, or any regulation promulgated
         thereunder, including, without limitation, Regulations G, T, U, and X
         of the Board of Governors of the Federal Reserve System;

         the caption "Description of the Preferred Securities," "Description of
         the Guarantee," "Description of the Convertible Debentures," "Effect of
         Obligations under the Convertible Debentures and the Guarantee," and

         summary of the terms of the Preferred Securities, the Convertible
         Debentures, the Guarantee, the Company Common Stock and the documents
         referred to therein fairly summarize or describe such terms and
         documents in all material respects;

                  (hh) When the Preferred Securities and Guarantee are issued
         and delivered pursuant to this Agreement and when the Convertible
         Debentures are issued (whether initially to the Trust or subsequently
         to the holders of Preferred Securities in exchange for the Preferred
         Securities), the Preferred Securities, the Guarantee and the
         Convertible Debentures will not be of the same class (within the
         meaning of Rule 144A under the Act) as securities which are listed on a
         national securities exchange registered under Section 6 of the Exchange
         Act, or quoted in a U.S. automated inter-dealer quotation system;

                  (ii) The Company is subject to Section 13 or 15(d) of the

         Securities, the Convertible Debentures or the Guarantee by means of any
         general solicitation or general advertising within the meaning of Rule
         502(c) under the Act or, with respect to any such securities sold
         outside the United States to non-U.S. persons (as defined in Rule 902
         under the Act), by means of any directed selling efforts within the
         meaning of Rule 902 under the Securities Act and the Company, any
         affiliate of the Company and any person acting on its or their behalf
         (other than the Initial Purchasers, as to which no representation is

         restrictions" (as defined in such Rule 902) requirements of Regulation
         S;

                  (kk) Within the preceding six months, with the exception of
         the concurrent offering by the Company of up to 2,137,500 shares of
         Company Common Stock pursuant to a registered public offering (the
         "Company Common Stock Offering") and any securities issued pursuant to

         Securities, Convertible Debentures, Guarantee or Company Common Stock,
         other than securities sold to the Initial Purchasers hereunder and
         other than shares of Company Common Stock issuable pursuant to benefit
         plans maintained for the officers, directors or employees of the
         Company. The Trust and the Company will take reasonable precautions
         designed to insure that any offer or sale, direct or indirect, in the
         United States or to any U.S. person (as defined in Rule 902 under the
         Act) of any Preferred Securities, Convertible Debentures, Guarantee and
         shares of Company Common Stock or any substantially similar security
         issued by the Trust and the Company, within six months subsequent to
         the date on which the distribution of the Securities has been completed
         (as notified to the Trust and the Company by Bear, Stearns & Co. Inc.),
         is made under restrictions and other circumstances reasonably designed
         not to affect the status of the offer and sale of the Preferred
         Securities, Convertible Debentures, Guarantee and shares of Company
         Common Stock issuable upon conversion of the Preferred Securities and
         the Convertible Debentures in the United States and to U.S. persons

         agent, sold, offered for sale, solicited offers to buy or otherwise
         negotiated in respect of, any security (as defined in the Act) which is
         or will be integrated with the sale of the Preferred Securities, the

         2.       Purchase, Sale and Delivery of the Preferred Securities.

                  (a) On the basis of the representations, warranties,
         agreements and covenants herein contained and subject to the terms and
         conditions herein set forth, the Trust and the Company agree that the
         Trust shall issue and sell to each of the Initial Purchasers, and each
         of the Initial Purchasers, severally and not jointly, agrees to
         purchase at a purchase price of $25 per Preferred Security, the number
         of Firm Securities set forth opposite such Initial Purchaser's name in
         Schedule I hereto, plus such additional number of Firm Securities which
         such Initial Purchaser may become obligated to purchase pursuant to
         Section 8 hereof.

                  (b) The Trust and the Company also grant to the Initial
         Purchasers an option to purchase, solely for the purpose of covering
         over-allotments in the sale of Firm Preferred Securities, if any, all
         or any portion of the Optional Securities at the purchase price per
         Preferred Security set forth above. The option granted hereby may be
         exercised as to all or any part of the Optional Securities at any time
         (but only once) within 30 days after the date of the Offering Circular.
         The Initial Purchasers shall not be under any obligation to purchase
         any Optional Securities prior to the exercise of such option. The
         option granted hereby may be exercised by Bear, Stearns & Co. Inc.
         giving written notice to the Company setting forth the number of
         Optional Securities to be purchased and the date and time for delivery
         of and payment for such Optional Securities and stating that the
         Optional Securities referred to therein are to be used for the purpose
         of covering over-allotments in connection with the distribution and
         sale of the Firm Securities. If such notice is given prior to the First
         Closing Date (as defined below), the date set forth therein for such
         delivery and payment shall not be earlier than two full business days
         thereafter or the First Closing Date, whichever occurs later. If such
         notice is given on or after the First Closing Date, the date set forth
         therein for such delivery and payment shall not be earlier than three
         full business days thereafter. In either event, the date so set forth
         shall not be more than 15 full business days after the date of such
         notice. The date and time set forth in such notice is herein called the
         "Option Closing Date." Upon exercise of the option, the Company shall
         become obligated to sell to the Initial Purchasers, and, subject to the
         terms and conditions herein set forth, the Initial Purchasers shall
         become obligated to purchase, for the account of each Initial
         Purchaser, from the Company, severally and not jointly, the number of
         Optional Securities specified in such notice. Optional Securities shall
         be purchased for the accounts of the Initial Purchasers in proportion
         to the number of Firm Securities set forth opposite such Initial
         Purchaser's name in Schedule I hereto, except that the respective
         purchase obligations of each Initial Purchaser shall be adjusted so
         that no Initial Purchaser shall be obligated to purchase fractional
         Optional Securities.

                  (c) A global certificate or certificates for the Firm
         Securities which each Initial Purchaser has agreed to purchase
         hereunder shall be delivered by or on behalf of the Trust to Bear,
         Stearns & Co. Inc., through the facilities of DTC, for the account of
         such Initial Purchaser against payment by such Initial Purchaser or on
         its behalf of the purchase price therefor by wire transfer to an
         account designated by the Trust in Federal (same day) funds, such time
         of delivery against payment being herein referred to as the "First
         Closing Date." The First Closing Date and the Option Closing Date are
         herein individually referred to as the "Closing Date" and collectively
         referred to as the "Closing Dates." A global certificate or



                                       13
<PAGE>   14

         certificates for the Optional Securities which each Initial Purchaser
         shall have agreed to purchase hereunder shall be similarly delivered by
         or on behalf of the Trust on the Option Closing Date. The global
         certificate or certificates for the Preferred Securities will be in
         such denominations and registered in such names as Bear, Stearns & Co.
         Inc. may request not less than 48 hours prior to the First Closing Date
         or the Option Closing Date, as the case may be. Such certificate or
         certificates will be made available for checking at the office of DTC
         or its designated custodian, at least 24 hours prior to the First
         Closing Date or the Option Closing Date, as the case may be. It is
         understood that the Representatives may (but shall not be obligated to)
         make payment on behalf of any Initial Purchaser for the Preferred
         Securities to be purchased by such Initial Purchaser. No such payment
         shall relieve such Initial Purchaser from any of its obligations
         hereunder. The Preferred Securities to be purchased by each Initial
         Purchaser hereunder will be represented by one or more global Preferred
         Securities in book-entry form which will be deposited by or on behalf
         of the Trust with DTC or its designated custodian.

                  (d) As compensation to the Initial Purchasers for their
         commitments hereunder, and in view of the fact that the proceeds of the
         sale of the Preferred Securities will be used by the Trust to purchase
         the Convertible Debentures of the Company at each Closing Date the
         Company will pay to Bear, Stearns & Co. Inc., for the accounts of the
         several Initial Purchasers, an amount equal to $0.75 per Preferred
         Security for the Preferred Securities to be delivered by the Company at
         such Closing Date.

         3. Covenants of the Initial Purchasers. Upon the authorization by you
of the release of the Preferred Securities, the several Initial Purchasers
propose to offer the Preferred Securities for sale upon the terms and conditions
set forth in this Agreement and the Offering Circular, and each Initial
Purchaser hereby represents and warrants to and agrees with the Trust and the
Company that:

                  (a) It will offer and sell the Preferred Securities only (i)
         to persons who it reasonably believes are "qualified institutional
         buyers" ("QIBs") within the meaning of Rule 144A of the Securities Act
         under the Act in transactions meeting the requirements of Rule 144A,
         (ii) in an offshore transaction complying with Rule 903 or Rule 904 of
         Regulation S under the Securities Act, and (iii) upon the terms and
         conditions set forth in Annex I to the Trust Agreement; and

                  (b) It will not offer or sell the Preferred Securities, the
         Convertible Debentures, the Guarantee or the shares of Company Common
         Stock issuable upon conversion of the Preferred Securities and the
         Convertible Debentures by any form of general solicitation or general
         advertising, including but not limited to the methods described in Rule
         502(c) under the Act.

         4. Covenants of the Company. The Trust and the Company, jointly and
severally, agree with each of the Initial Purchasers:

         thereof; and to furnish you with copies thereof;

                  (b) Promptly from time to time to take such action as you may

         Convertible Debentures for offering and sale under the securities laws
         of such jurisdictions in the United States as you may request and to
         comply with such laws so as to permit the continuance of sales and
         dealings therein in such jurisdictions for as long as may be necessary
         to complete the distribution of the Preferred Securities, provided that
         in connection therewith the Company shall not be required to qualify as
         a foreign corporation or to file a general consent to service of
         process in any jurisdiction;

                  (c) To furnish the Initial Purchasers with five copies of the

         authorized officer of the Company with the independent accountants'

         amendment or supplement containing amendments to the financial
         statements covered by such report, signed by the accountants, and

         time reasonably request, and if, at any time prior to the Effective
         Time of the Shelf Registration Statement (each as defined in the
         Registration Rights Agreement), any event shall have occurred as a
         result of which the Offering Circular as then amended or supplemented
         would include an untrue statement of a material fact or omit to state
         any material fact necessary in order to make the statements therein, in
         the light of the circumstances under which they were made when such
         Offering Circular is delivered, not misleading, or, if for any other
         reason it shall be necessary or desirable during such same period to
         amend or supplement the Offering Circular, to notify you and upon your
         request to prepare and furnish without charge to each Initial Purchaser
         and to any dealer in securities as many copies as you may from time to
         time reasonably request of an amended Offering Circular or a supplement
         to the Offering Circular which will correct such statement or omission.

         securities" under Rule 144 of the Securities Act that have been
         reacquired by any of them;

<PAGE>   18

                  (p) The Trust and the Company will not take, directly or
         indirectly, any action designed to cause or result in, or which might

                  "significant" as such term is defined in Regulation S-X
                  promulgated by the Commission has been duly organized and is
                  validly existing under the laws of its jurisdiction of

                  corporate or partnership power and authority to own its

                  issued and outstanding shares of capital stock of the

                           (iv)   The Company is duly qualified to do business
                  as a foreign corporation in good standing in all jurisdictions
                  where the failure to so qualify would have a material adverse
                  effect upon the Company and its subsidiaries, taken as a
                  whole. The Company holds all licenses, certificates, permits,
                  franchises and authorizations from governmental authorities
                  that are material to the conduct of its business in all
                  locations in which such business is currently being conducted;

                           (v)    Except as contemplated by the Registration
                  Rights Agreement, to the best of such counsel's knowledge, no
                  holder of any security of the Company has any right to require
                  registration of shares of Company Common Stock or any other
                  security of the Company, except for those registration rights
                  granted in connection with the acquisition of Kinney.

                           (vi)   The Company Common Stock issuable upon the
                  conversion of the Preferred Securities and the Convertible
                  Debentures has been duly authorized by the Company and
                  reserved for issuance upon conversion and, if and when issued
                  in accordance with the Trust Agreement and the Indenture, will
                  be validly issued and fully paid and nonassessable and will
                  conform to the description of the Company Common Stock
                  contained in the Offering Circular; and the issuance of such
                  Company Common Stock is not subject to any preemptive rights
                  under the Delaware General Corporation Law, or any other
                  similar rights that entitle or will entitle any person to
                  acquire any shares of Company Common Stock from the Company
                  upon the issuance of such shares by the Company; and all of
                  the issued and outstanding Common Securities are directly
                  owned by the Company free and clear of all liens,
                  encumbrances, equities or claims;

                           (vii)  Each of the Company's subsidiaries is duly
                  qualified to do business in all jurisdictions where the
                  failure to so qualify would have a material adverse effect
                  upon the Company and its subsidiaries, taken as a whole. Each
                  subsidiary holds all licenses, certificates, permits,
                  franchises and authorizations from governmental authorities
                  that are material to the conduct of its business in all
                  locations in which such business is currently conducted;

                           (viii) Except as described in the Offering Circular,
                  there is not pending, or to the best knowledge of such counsel
                  threatened, any action, suit, proceeding, inquiry or
                  investigation, to which the Company or any of its
                  subsidiaries, or to which the property of the Company or any
                  of its subsidiaries is subject, before or brought by any court
                  or governmental agency or body, which, if determined adversely
                  to the Company, could result in any material adverse change in
                  the business, financial position, net worth or results of
                  operations, or could materially adversely affect the
                  properties or assets, of the Company;

                           (ix)  To the best knowledge of such counsel, the
                  Company or any of its subsidiaries is not in violation of any
                  law, ordinance, administrative or governmental rule or
                  regulation applicable to the Company or any of its
                  subsidiaries and material to the Company or any of its
                  subsidiaries or any decree of any court or governmental agency
                  or body having jurisdiction over the Company or any of its
                  subsidiaries;

                           (x)   All offers and sales of the Company's
                  securities prior to the date hereof were at all relevant times
                  duly registered or exempt from the registration requirements
                  of the Securities Act and were duly registered or the subject
                  of any exemption from the registration requirements of
                  applicable state securities or Blue Sky laws;

                           (xi)  The Exchange Act Reports (other than the
                  financial statements and related financial information
                  therein, as to which such counsel need express no opinion),
                  when they were filed with the Commission, complied as to form
                  in all material respects with the requirements of the Exchange
                  Act, and the Rules and Regulations; and nothing has come to
                  the attention of such counsel that causes him to believe that
                  any of such documents (other than the financial statements and
                  related financial information therein, as to which such
                  counsel need express no opinion), when they were so filed,
                  contained an untrue statement of a material fact or omitted to
                  state a material fact necessary in order to make the
                  statements therein, in the light of the circumstances under
                  which they were made when such documents were so filed, not
                  misleading;

                           (xii) The Company has full legal right, power and
                  authority to enter into this Agreement and the Guarantor
                  Agreements, and this Agreement and the Guarantor Agreements,
                  upon due execution, authentication and delivery, have been
                  duly authorized, executed, and delivered by the Company. This
                  Agreement and the Guarantor Agreements constitute valid and
                  legally binding obligations of the Company enforceable against
                  the Company in accordance with their terms, except to the
                  extent that (A) enforcement thereof may be limited by (1)
                  bankruptcy, insolvency, fraudulent transfer, rehabilitation,
                  conservation, reorganization, moratorium or other similar laws
                  now or hereafter in effect relating to the rights of creditors
                  generally, and (2) general principles of equity (regardless of
                  whether enforceability is considered in a proceeding at law or
                  in equity); (B) with respect to the Indenture, the waiver
                  contained in Section 515 of the Indenture may be deemed
                  unenforceable, (C) with respect to this Agreement, the
                  enforceability of indemnifica tion and contribution provisions
                  may be limited by federal and state securities laws and the
                  policies underlying such laws, and (D) with respect to the
                  Indenture, the enforceability, under certain circumstances, of
                  provisions imposing a payment obligation if the Company is
                  unable to comply timely with its registration obligations
                  under the Registration Rights Agreement may be limited by
                  applicable law; the Convertible Debentures are entitled to the
                  benefits provided by the Indenture;

                           (xiii) The Registration Rights Agreement has been
                  duly authorized and, when executed and delivered by the
                  Company, will constitute the valid and legally binding
                  obligations of the Company, enforceable in accordance with
                  their respective terms, except to the extent that (A)
                  enforcement thereof may be limited by (1) bankruptcy,
                  insolvency, reorganization, moratorium, fraudulent conveyance
                  or other similar laws now or hereafter in effect relating to
                  the rights of creditors generally, and (2) general principles
                  of equity (regardless of whether enforceability is considered
                  in a proceeding at law or in equity), (B) the enforceability
                  of indemnification and contribution provisions may be limited
                  by federal and state securities laws and the policies
                  underlying such laws, and (C) the enforceability, under
                  certain circum stances, of provisions imposing a payment
                  obligation if the Company is unable to comply timely with its
                  registration obligations under the Registration Rights
                  Agreement may be limited by applicable law.

                           (xiv)  Assuming the accuracy of your representations
                  contained in Section 3 hereof and your compliance with your
                  agreements therein set forth and assuming the accuracy of the

                  compliance with their agreements set forth in Section 4, no
                  registration of the Preferred Securities, the Convertible
                  Debentures or the Guarantee under the Act, and no
                  qualification of any indenture under the Trust Indenture Act
                  of 1939 with respect thereto, is required for the offer, sale
                  and initial resale of the Preferred Securities, the
                  Convertible Debentures or the Guarantee by the Initial
                  Purchasers in the manner contemplated by this Agreement and
                  the Offering Circular;

                           (xv)   The Company is not, and will not be as a
                  result of the consummation of the transactions contemplated by
                  this Agreement, an "investment company" within the meaning of
                  the Investment Company Act of 1940. The Trust is not required
                  to be registered under the Investment Company Act of 1940;

                           (xvi)  No consent, approval, authorization, or order
                  of any court or governmental agency or body or, to such
                  counsel's knowledge, any third party is required for the
                  performance of this Agreement or the Guarantor Agreements or
                  the consummation by the Company or the Trust of the
                  transactions contemplated hereby and thereby except such
                  authorizations, approvals, consents, orders, registrations or
                  filings as may be required under state securities or Blue Sky
                  laws in connection with the purchase and distribution of the
                  Preferred Securities, the Guarantee and the Convertible
                  Debentures or as may be required under the Registration Rights
                  Agreement;

                           (xvii) The Company's execution, delivery and
                  performance of this Agreement and the Guarantor Agreements and
                  the consummation of the transactions 



                                       22

                  contemplated hereby and thereby will not result in a breach or
                  violation of, or conflict with, any of the terms and
                  provisions of, or constitute a default by the Company under
                  the Amended and Restated Charter or bylaws of the Company. The
                  Company is not in violation of its Amended and Restated
                  Charter or bylaws or any law, administrative rule, or
                  regulation or arbitrator's or administrative or court decree,
                  judgment or order or in violation or default (there being no
                  existing state of facts which with notice or lapse of time or
                  both would constitute a default) in the performance or
                  observance of any Lien other than violations and defaults
                  which could not reasonably be expected to have a material
                  adverse effect on the business condition (financial or
                  otherwise), prospects, net worth, or results of operations of
                  the Company and its subsidiaries, taken as a whole;

                           (xviii) The execution, delivery and performance of
                  this Agreement, the Registration Rights Agreement and the
                  Guarantor Agreements by the Company and the consummation of
                  the transactions contemplated hereby and thereby, will not (1)
                  conflict with or result in a breach or violation of any of the
                  terms or provisions of, or constitute a default or cause an
                  acceleration of any obligation under or result in the
                  imposition or creation of (or the obligation to create or
                  impose) any Lien with respect to, any bond, note, debenture or
                  other evidence of indebtedness or any indenture, mortgage,
                  deed of trust, loan agreement or other agreement or instrument
                  to which the Company is a party or by which it is bound, or to
                  which any of the property or assets of the Company is or may
                  be subject, or (2) contravene any order of any court or
                  governmental agency or body having jurisdiction over the
                  Company or any of its properties, or violate or conflict with
                  any statute, rule or regulation or administrative or court
                  decree applicable to the Company, or any of its properties;

                           (xix)   The statements set forth in the Offering
                  Circular under the captions "Description of the Preferred
                  Securities," "Description of the Guarantee," "Descrip tion of
                  the Convertible Debentures," "Effect of Obligations Under the
                  Convertible Debentures and the Guarantee," and "Description of
                  Capital Stock," insofar as they purport to constitute a
                  summary of the terms of the Preferred Securities, the
                  Convertible Debentures, the Guarantee, the Company Common
                  Stock and the documents referred to therein, and under the
                  caption "Plan of Distribution" insofar as they purport to
                  describe the provisions of the law and the documents described
                  therein, fairly summarize or describe such terms, documents
                  and laws in all material respects.

                           In addition to the matters set forth above, such
                  opinion shall also include a statement to the effect that such
                  counsel have participated in conferences with officers and
                  other representatives of the Company and the Trust,
                  representatives of the independent public accountants of the
                  Company, representatives of the Initial Purchasers and their
                  counsel at which the contents of the Offering Circular and
                  related matters were discussed and, although such counsel are
                  not passing on and do

                  not assume any responsibility for the accuracy, completeness
                  or fairness contained in the Offering Circular, that nothing
                  has come to the attention of such counsel which leads them to
                  believe that the Offering Circular or any amendment or
                  supplement thereto, or any document incorporated by reference
                  therein, as of the respective dates thereof and as of the
                  Closing Date, contained or contains an untrue statement of a
                  material fact or omitted or omits to state a material fact
                  required to be stated therein or necessary to make the
                  statements therein not misleading (except that such counsel
                  need express no view as to financial statements, schedules and
                  other financial information included therein). In rendering
                  such opinion, counsel may rely as to matters of fact, to the
                  extent counsel deems proper, on certificates of responsible
                  officers of the Company and public officials;

                  (c) Harwell Howard Hyne Gabbert & Manner P.C., special
         Delaware counsel for the Trust, shall have furnished to you their
         written opinions, dated the Closing Date, in form and substance
         satisfactory to you, to the effect that:

                           (i)   The Trust has been duly created and is validly
                  existing in good standing as a business trust under the

                           (ii)  The Trust Securities conform to the description
                  thereof contained in the Offering Circular;

                           (iii) Under the Delaware Business Trust Act and the
                  Trust Agreement, the Trust has the trust power and authority
                  (a) to own its properties and conduct its business, (b) to
                  execute and deliver this Agreement, the Trust Agreement, the
                  Registration Rights Agreement and any other agreement or
                  certificate required to be executed and delivered by the Trust
                  hereby and thereby and (c) to issue and perform its
                  obligations under the Trust Securities, as described in the
                  Trust Agreement;

                           (iv)  To the best of such counsel's knowledge, the
                  Trust is not a party to or bound by any agreement or
                  instrument other than this Agreement, the Trust Agreement and
                  the agreements and instruments contemplated by the Trust
                  Agreement and described in the Offering Circular; and there
                  are no legal or governmental proceedings pending to which the
                  Trust is a party or of which any property of the Trust is the
                  subject and no such proceedings are threatened or contemplated
                  by governmental authorities or threatened by others;

                           (v)   The execution, delivery and performance of this
                  Agreement and the Registration Rights Agreement by the Trust,
                  and the consummation of the transactions contemplated hereby
                  and thereby, will not (1) conflict with or result in a breach
                  or violation of the Trust Agreement or any of the terms or
                  provisions thereof, or (2) contravene any order of any court
                  of governmental agency or body having jurisdiction over the
                  Trust or any of its properties, or violate or conflict with

                  any statue, rule or regulation or administrative or court
                  decree applicable to the Trust or any of its properties;

                           (vi)   The Trust has full legal right, power and
                  authority to enter into this Agreement and the Trust
                  Agreement, and this Agreement and the Trust Agreement, upon
                  due execution, authentication and delivery, have been duly
                  authorized, executed, and delivered by the Trust. This
                  Agreement and the Trust Agreement constitute valid and legally
                  binding obligations of the Trust enforceable against the Trust
                  and the Trustees in accordance with their terms, except to the
                  extent that (A) enforcement thereof may be limited by (1)
                  bankruptcy, insolvency, fraudulent transfer, rehabilitation,
                  conservation, reorganization, moratorium or other similar laws
                  now or hereafter in effect relating to the rights of creditors
                  generally, and (2) general principles of equity (regardless of
                  whether enforceability is considered in a proceeding at law or
                  in equity); (B) with respect to this Agreement, the
                  enforceability of indemnification and contribution provisions
                  may be limited by federal and state securities laws and the
                  policies underlying such laws;

                           (vii)  The Registration Rights Agreement has been
                  duly authorized and when executed and delivered by the Trust
                  (assuming the due authorization, execution and delivery
                  thereof by the other parties thereto) will constitute the
                  valid and legally binding obligations of the Trust,
                  enforceable in accordance with its terms, except to the extent
                  that (A) enforcement thereof may be limited by (1) bankruptcy,
                  insol vency, reorganization, moratorium, fraudulent conveyance
                  or other similar laws now or hereafter in effect relating to
                  the rights of creditors generally, and (2) general principles
                  of equity (regardless of whether enforceability is considered
                  in a proceeding at law or in equity), (B) the enforceability
                  of indemnification and contribution provisions may be limited
                  by federal and state securities laws and the policies
                  underlying such laws, and (C) the enforceability, under
                  certain circum stances, of provisions imposing a payment
                  obligation if the Company is unable to comply timely with its
                  registration obligations under the Registration Rights
                  Agreement may be limited by applicable law.

                           (viii) The Trust Securities have been duly authorized
                  by the Trust, and upon issuance thereof and payment therefor
                  as provided herein, will be validly issued, and, subject to
                  the terms of the Trust Agreement, fully paid and nonassessable
                  undivided beneficial interests in the assets of the Trust;
                  none of the issued Trust Securities have been issued in
                  violation of or subject to any preemptive rights provided for
                  by the Delaware Business Trust Act, or other law or in the
                  Trust Agreement. There are no preemptive rights or other
                  rights to subscribe for or to purchase, or any restriction
                  upon the transfer of, the Trust Securities pursuant to the
                  Trust Agreement, bylaws or other governing documents or, to
                  such counsel's knowledge, any agreement or other instrument to
                  which the Trust is a party or by which it may be bound except
                  as described in the Offering Circular and except for
                  restrictions on transfer imposed

                  under applicable securities laws.

                           (ix) The Securityholders, as beneficial owners of the
                  Trust, will be entitled to the same limitation of personal
                  liability extended to stockholders of private corporations for
                  profit organized under the General Corporation Law of the
                  State of Delaware, except that the Securityholders may be
                  obligated to make payments as set forth in the Trust
                  Agreement;

                           (x)  No consent, approval, authorization, or order of
                  any court or governmental agency or body of the State of
                  Delaware or, to such counsel's knowledge, any third party is
                  required for the performance of this Agreement or the Trust
                  Agreement or the Registration Rights Agreement or the
                  consummation by the Trust of the transactions contemplated
                  hereby and thereby;

                           (xi) The purchase of the Convertible Debentures by
                  the Trust does not, and the distribution of the Convertible
                  Debentures by the Trust will not, in each case in the
                  circumstances contemplated by the Trust Agreement, conflict
                  with or result in a breach or violation of any of the terms or
                  provisions of the Trust Agreement or any Delaware statute or
                  any order, rule or regulation of any Delaware governmental
                  agency or body having jurisdiction over the Trust or any of
                  its properties; and

                           In addition to the matters set forth above, such
                  opinion shall also include a statement to the effect that such
                  counsel has participated in conferences with officers and
                  other representatives of the Company and the Trust,
                  representatives of the independent public accountants of the
                  Company, representatives of the Initial Purchasers and their
                  counsel at which the contents of the Offering Circular and
                  related matters were discussed and, although such counsel is
                  not passing on and does not assume any responsibility for the
                  accuracy, completeness or fairness contained in the Offering
                  Circular, nothing has come to the attention of such counsel
                  which leads them to believe that the Offering Circular or any
                  amendment or supplement thereto, or any document incorporated
                  by reference therein, as of the respective dates thereof and
                  as of the Closing Date, contained or contains an untrue
                  statement of a material fact or omitted or omits to state a
                  material fact required to be stated therein or necessary to
                  make the statements therein not misleading (except that such
                  counsel need express no view as to financial statements,
                  schedules and other financial information included therein).
                  In rendering such opinion, counsel may rely as to matters of
                  fact, to the extent counsel deems proper, on certificates of
                  responsible officers of the Company and public officials;

                  (d) Skadden, Arps, Slate, Meagher & Flom LLP, counsel to the
         Trust and the Company in relation to the classification of the Trust
         for United States federal income tax purposes, shall have furnished
         their written opinion to the effect that:



                                       26
<PAGE>   27

                           (i)  under then current law and assuming full
                  compliance with the terms of the Trust Agreement and the
                  Indenture (and certain other documents), and based on certain
                  facts and assumptions contained in such opinion, the Trust
                  will be classified for United States federal income tax
                  purposes as a grantor trust and not as an association taxable
                  as a corporation; and

                           (ii) The statements made in the Offering Circular
                  under the caption "United States Federal Income Taxation" are
                  a fair and accurate summary of certain of the United States
                  federal income tax issues relating to the purchase, ownership
                  and the disposition of the Preferred Securities.

                  (e) On the date of the Offering Circular prior to the
         execution of this Agreement and also at the Closing Date, KMPG Peat
         Marwick LLP shall have furnished to you a letter or letters, dated the
         respective dates of delivery thereof, in form and substance
         satisfactory to the Initial Purchasers, with respect to the
         consolidated financial statements and certain financial information
         incorporated by reference in or contained in the Offering Circular;

                  (f) The Trust Agreement, the Guarantee and the Indenture shall
         have been executed and delivered, in each case in a form reasonably
         satisfactory to you;

                  (g) (i) Subsequent to the respective dates as of which
         information is given in the Offering Circular, and except as stated
         therein, neither the Company nor the Trust have sustained any material
         loss or interference with their business or properties from fire,
         flood, hurricane, earthquake, accident or other calamity, whether or
         not covered by insurance, or from any labor dispute or any court or
         governmental action, order or decree, or become a party to or the
         subject of any litigation which is material to the Company or the
         Trust, nor shall there have been any material adverse change, or any
         development involving a prospective material adverse change, in the
         business, properties, key personnel, capitaliza tion, net worth,
         results of operations or condition (financial or other) of the Company
         or the Trust, which loss, interference, litigation or change, in the
         judgment of the Initial Purchasers shall render it unadvisable to
         commence or continue the offering or the delivery of the Preferred
         Securities on the terms and in the manner contemplated in this
         Agreement and in the Offering Circular.

                  (h) On or after the date hereof, none of the Company's debt
         securities or the Preferred Securities are rated by any "nationally
         recognized statistical rating organization," as that term is defined by
         the Commission for purposes of Rule 436(g)(2) under the Act;

                  (i) On or after the date hereof there shall not have occurred
         any of the following: (i) trading in securities on the New York Stock
         Exchange, the American Stock Exchange, or the over-the-counter market
         shall have been suspended or materially limited or minimum or maximum
         prices shall have been established on either of such Exchanges or such
         market, or a banking moratorium shall have been declared by Federal or
         state authorities; (ii) if at or 



                                       27
<PAGE>   28

         prior to the Closing Date trading in securities of the Company shall
         have been suspended; or (iii) if there shall have been such a material
         change in general economic, political or financial conditions or if the
         effect of international conditions on the financial markets in the
         United States such as in the judgment of the Initial Purchasers makes
         it impracticable or inadvisable to proceed with the offering or the
         delivery of the Preferred Securities on the terms and in the manner
         contemplated in the Offering Circular;

                  (j) The Trust and the Company shall have furnished or caused
         to be furnished to you at the Closing Date certificates of trustees of
         the Trust and officers of the Company satisfactory to you as to the
         accuracy of the representations and warranties of the Trust and the
         Company herein at and as of such Closing Date, as to the performance by
         the Trust and the Company of all of their obligations hereunder to be
         performed at or prior to such Closing Date, as to the matters set forth
         in subsections (f) and (g) of this Section and as to such other matters
         as you may reasonably request.

                  (k) Each of the directors of the Company and each of the
         officers of the Company named in the Offering Circular shall have
         executed and delivered to you in a lock-up agreement addressed to you
         in a form satisfactory to you and substantially similar to the form of
         lock-up agreement contained in Section 4(e).

         All such opinions, certificates, letters and documents delivered
         pursuant to this Agreement will comply with the provisions hereof only
         if they are reasonably satisfactory to the Bear, Stearns & Co. Inc. and
         their counsel. The Company shall furnish to the Representatives such
         conformed copies of such opinions, certificates, letters and documents
         in such quantities as the Representatives shall reasonably request.

         The respective obligations of the Initial Purchasers to purchase and
pay for the Optional Securities shall be subject, in their reasonable
discretion, to each of the foregoing conditions to purchase the Firm Preferred
Securities, except that all references to the "Closing Date" shall be deemed to
refer to the Option Closing Date, if it shall be a date other than the Closing
Date.

         7. Indemnification and Contribution.

                  (a) The Company and the Trust, severally and jointly, agree to
         indemnify and hold harmless each Initial Purchaser, and each person, if
         any, who controls any Initial Purchaser within the meaning of the
         Securities Act, against any losses, claims, damages or liabilities,
         joint or several, to which such Initial Purchaser or controlling person
         may become subject under the Securities Act or otherwise, insofar as
         such losses, claims, damages or liabilities (or actions in respect
         thereof) arise out of or are based in whole or in part upon any untrue
         statement or alleged untrue statement of any material fact contained in
         the Preliminary Offering Circular or Offering Circular, or any
         amendment or supplement thereto, or in any Blue Sky application or
         other written information furnished by the Company filed in any state
         or other jurisdiction in order to qualify any or all of the Preferred
         Securities under the 



                                       28
<PAGE>   29

         securities laws thereof (a "Blue Sky Application") or arise out of or
         are based upon the omission or alleged omission to state therein a
         material fact required to be stated therein or necessary to make the
         statements therein not misleading, and will reimburse each Initial
         Purchaser and each such controlling person for any legal or other
         expenses reasonably incurred by such Initial Purchaser or such
         controlling person in connection with investigating or defending any
         such loss, claim, damage, liability or action as such expenses are
         incurred; provided, however, that the Company and the Trust will not be
         liable in any such case to the extent that any such loss, claim,
         damage, or liability arises out of or is based upon any untrue
         statement or alleged untrue statement or omission or alleged omission
         made in the Preliminary Offering Circular or Offering Circular or such
         amendment or such supplement or any Blue Sky Application in reliance
         upon and in conformity with written information furnished to the
         Company or the Trust by any Initial Purchaser specifically for use
         therein (it being understood that the only information so provided by
         the Initial Purchasers is the information included in the last
         paragraph on the cover page, the fifth paragraph on page three, and in
         the first, second, fourth and fourteenth paragraphs under the caption
         "Plan of Distribution" in any Preliminary Offering Circular and the
         Offering Circular).

                  (b) Each Initial Purchaser, severally and not jointly, will
         indemnify and hold harmless each of the Trust and the Company and each
         person, if any, who controls the Company within the meaning of the
         Securities Act, and each Administrative Trustee or any other person who
         controls the Trust within the meaning of the Securities Act, against
         any losses, claims, damages or liabilities to which the Trust or
         Company or any such director, officer or controlling person may become
         subject, under the Securities Act or otherwise, insofar as such losses,
         claims, damages or liabilities (or actions in respect thereof) arise
         out of or are based upon any untrue statement or alleged untrue
         statement of any material fact contained in the Preliminary Offering
         Circular or Offering Circular, or any amendment or supplement thereto,
         or any Blue Sky Application, or arise out of or are based upon the
         omission or the alleged omission to state in the Preliminary Offering
         Circular or Offering Circular or any amendment or supplement thereto or
         any Blue Sky Application a material fact required to be stated therein
         or necessary to make the statements therein not misleading, in each
         case to the extent, but only to the extent, that such untrue statement
         or alleged untrue statement or omission or alleged omission was made in
         reliance upon and in conformity with written information furnished to
         the Trust and the Company by any Initial Purchaser specifically for use
         therein (it being understood that the only information so provided is
         the information included in the last paragraph on the cover page, the
         fifth paragraph on page three, and in the first, second, fourth and
         fourteenth paragraphs under the caption "Plan of Distribution" in the
         Preliminary Offering Circular and the Offering Circular);

                  (c) Promptly after receipt by an indemnified party under this
         Section 7 of notice of the commencement of any action, including
         governmental proceedings, such indemnified party will, if a claim in
         respect thereof is to be made against the indemnifying party under this
         Section 7 notify the indemnifying party of the commencement thereof;
         but the omission so to notify the indemnifying party will not relieve
         it from any liability which it may have to 



                                       29
<PAGE>   30

         any indemnified party otherwise than under this Section 7. In case any
         such action is brought against any indemnified party, and it notifies
         the indemnifying party of the commencement thereof, the indemnifying
         party will be entitled to participate therein, and to the extent that
         it may wish, jointly with any other indemnifying party similarly
         notified, to assume the defense thereof, with counsel reasonably
         satisfactory to such indemnified party; and after notice from the
         indemnifying party to such indemnified party of its election to so
         assume the defense thereof, the indemnifying party will not be liable
         to such indemnified party under this Section 7 for any legal or other
         expenses subsequently incurred by such indemnified party in connection
         with the defense thereof other than reasonable costs of investigation
         except that the indemnified party shall have the right to employ
         separate counsel if, in its reasonable judgment, it is advisable for
         the indemnified party and any other Initial Purchaser to be represented
         by separate counsel, and in that event the fees and expenses of
         separate counsel shall be paid by the indemnifying party. An
         indemnifying party shall not be liable for any settlement of any claim
         or action effected without its written consent; provided, however, that
         such consent was not unreasonably withheld.

                  Neither the Company nor the Trust will, without prior written
         consent of each Representative, settle or compromise or consent to the
         entry of any judgment in any pending or threatened claim, action, suit
         or proceeding (or related cause of action or portion thereof) in
         respect of which indemnification may be sought hereunder (whether or
         not such Initial Purchaser is a party to such claim, action, suit or
         proceeding), unless such settlement, compromise or consent includes an
         unconditional release of such Initial Purchaser from all liability
         arising out of such claim, action, suit or proceeding (or related cause
         of action or portion thereof).

                  (d) In order to provide for just and equitable contribution in
         circumstances in which the indemnity agreement provided for in the
         preceding part of this Section 7 is for any reason held to be
         unavailable to the Initial Purchasers, the Company, or the Trust or is
         insufficient to hold harmless an indemnified party, then the Company
         and the Trust shall contribute to the damages paid by the Initial
         Purchasers, and the Initial Purchasers shall contribute to the damages
         paid by the Company and the Trust provided, however, that 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. In
         determining the amount of contribution to which the respective parties
         are entitled, there shall be considered the relative benefits received
         by each party from the offering of the Preferred Securities (taking
         into account the portion of the proceeds of the offering realized by
         each), the parties' relative knowledge and access to information
         concerning the matter with respect to which the claim was asserted, the
         opportunity to correct and prevent any statement or omission, and any
         other equitable considerations appropriate under the circumstances. The
         Company, the Trust and the Initial Purchasers agree that it would not
         be equitable if the amount of such contribution were determined by pro
         rata or per capita allocation (even if the Initial Purchasers were
         treated as one entity for such purpose). No Initial Purchaser or person
         controlling such Initial 



                                       30
<PAGE>   31

         Purchaser shall be obligated to make contribution hereunder which in
         the aggregate exceeds the amount per Preferred Security paid to such
         Initial Purchaser as compensation for its commitment to purchase
         Preferred Securities hereunder, less the aggregate amount of any
         damages which such Initial Purchaser and its controlling persons have
         otherwise been required to pay in respect of the same or any similar
         claim. The Initial Purchasers' obligations to contribute hereunder are
         several in proportion to their respective underwriting obligations and
         not joint. For purposes of this Section, each person, if any, who
         controls an Initial Purchaser within the meaning of Section 15 of the
         Securities Act shall have the same rights to contribution as such
         Initial Purchaser, and each director of the Company, and each person,
         if any, who controls the Company within the meaning of Section 15 of
         the Securities Act, shall have the same rights to contribution as the
         Company, and each Administrative Trustee and each person who controls
         the Trust within the meaning of Section 15 of the Securities Act, shall
         have the same rights to contribution as the Trust.

         8. Default of Initial Purchasers. If any Initial Purchaser defaults in
its obligation to purchase Preferred Securities hereunder and if the total
number of Preferred Securities which such defaulting Initial Purchaser agreed
but failed to purchase is ten percent or less of the total number of Preferred
Securities to be sold hereunder, the non-defaulting Initial Purchasers shall be
obligated severally to purchase (in the respective proportions which the number
of Preferred Securities set forth opposite the name of each non-defaulting
Initial Purchaser in Schedule I hereto bears to the total number of Preferred
Securities set forth opposite the names of all the non-defaulting Initial
Purchasers), the Preferred Securities which such defaulting Initial Purchaser or
Initial Purchasers agreed but failed to purchase. If any Initial Purchaser so
defaults and the total number of Preferred Securities with respect to which such
default or defaults occur is more than ten percent of the total number of
Preferred Securities to be sold hereunder, and arrangements satisfactory to the
other Initial Purchasers and the Company for the purchase of such Preferred
Securities by other persons (who may include the non-defaulting Initial
Purchasers) are not made within 36 hours after such default, this Agreement,
insofar as it relates to the sale of the Preferred Securities, will terminate
without liability on the part of the non-defaulting Initial Purchasers or the
Company except for (i) the provisions of Section 7 hereof, and (ii) the expenses
to be paid or reimbursed by the Company pursuant to Section 5. As used in this
Agreement, the term "Initial Purchaser" includes any person substituted for an
Initial Purchaser under this Section 8. Nothing herein shall relieve a
defaulting Initial Purchaser from liability for its default.

         9. Survival Clause. The respective representations, warranties,
agreements, covenants, indemnities and other statements of the Trust and the
Company, its officers and the Initial Purchasers set forth in this Agreement or
made by or on behalf of them, respectively, pursuant to this Agreement shall
remain in full force and effect, regardless of (i) any investigation made by or
on behalf of the Company, any of its officers or directors, any Initial
Purchaser or any controlling person, the Trust or any Administrative Trustee or
controlling person of the Trust and (ii) delivery of and payment for the
Preferred Securities. The respective agreements, covenants, indemnities and
other statements set forth in Section 5 and Section 7 hereof shall remain in
full force and effect, regardless of any termination or cancellation of this
Agreement.

         10. Termination.

                  (a) This Agreement may be terminated by the Representatives by
         notice to the Company and the Trust (i) in the event that at or prior
         to the First Closing Date the Company or the Trust shall have failed,
         refused, or been unable to perform any agreement on the part of the
         Company or the Trust to be performed hereunder or any other condition
         to the obligations of the Initial Purchasers hereunder is not
         fulfilled; (iii) if at or prior to the Closing Date trading in
         securities on the New York Stock Exchange, the American Stock Exchange,
         or the over-the-counter market shall have been suspended or materially
         limited or minimum or maximum prices shall have been established on
         either of such Exchanges or such market, or a banking moratorium shall
         have been declared by Federal or state authorities; (iv) if at or prior
         to the Closing Date trading in securities of the Company shall have
         been suspended; or (v) if there shall have been such a material change
         in general economic, political or financial conditions or if the effect
         of international conditions on the financial markets in the United
         States shall be such as, in the reasonable judgment of the Initial
         Purchasers, it is inadvisable to commence or continue the offering of
         the Preferred Securities at the offering price to the public set forth
         on the cover page of the Offering Circular or to proceed with the
         delivery of the Preferred Securities.

                  (b) Termination of this Agreement pursuant to this Section 10
         shall be without liability of any party to any other party other than
         as provided in Sections 5 and 7 hereof.

         11. Notices. All communications hereunder shall be in writing and, if
sent to any of the Initial Purchasers, shall be mailed or delivered or
telegraphed and confirmed in writing to the Representatives in care of Bear,
Stearns & Co. Inc., 945 Park Avenue, New York, New York 10167, Attention: Tom
Harney, or if sent to the Company or the Trust shall be mailed, delivered or
telegraphed and confirmed in writing to the Company and the Trust at 2401 21st
Avenue South, Suite 200, Nashville, Tennessee 37212, Attention: Monroe J.
Carell, Jr.

         12. Miscellaneous. This Agreement shall inure to the benefit of and be
binding upon the several Initial Purchasers, the Company, the Trust and their
respective successors and legal representatives. Nothing expressed or mentioned
in this Agreement is intended or shall be construed to give any other person any
legal or equitable right, remedy or claim under or in respect of this Agreement.
This Agreement and all conditions and provisions hereof are intended to be for
the sole and exclusive benefit of the Company, the Trust and the several Initial
Purchasers and for the benefit of no other person except that (i) the
representations and warranties of the Company and the Trust contained in this
Agreement shall also be for the benefit of any person or persons who control any
Initial Purchaser within the meaning of Section 15 of the Securities Act, and
(ii) the indemnities by the Initial Purchasers shall also be for the benefit of
the directors of the Company and any person or persons who control the Company
within the meaning of Section 15 of the Securities Act and the Administrative
Trustees and any person or persons who control the Trust within the meaning of
Section 15 of the Securities Act. No purchaser of Preferred Securities from any
Initial Purchaser will



                                       32
<PAGE>   33

be deemed a successor because of such purchase. The validity and interpretation
of this Agreement shall be governed by the laws of the State of Tennessee. This
Agreement may be executed in two or more counterparts, each of which shall be
deemed an original, but all of which together shall constitute one and the same
instrument. You hereby represent and warrant to the Company and the Trust that
you have authority to act hereunder on behalf of the several Initial Purchasers,
and any action hereunder taken by you will be binding upon all the Initial
Purchasers.

         13. No Liability of Property Trustee, Delaware Trustee or Guarantee
Trustee.

                  It is expressly understood and agreed by the parties hereto
that (a) each of the representations, undertakings and agreements herein made on
the part of the Trust is made and intended not as representations, warranties,
covenants, undertakings and agreements of any Trustee of the Trust, including,
without limitation, Chase Bank of Texas, National Association as Guarantee
Trustee or Property Trustee or Chase Manhattan Bank Delaware as Delaware
Trustee, in their individual capacity, but is made and intended for the purpose
of binding only the Trust, and (b) under no circumstances shall any Trustee,
including Chase Bank of Texas, National Association as Guarantee Trustee or
Property Trustee or Chase Manhattan Bank Delaware as Delaware Trustee be
personally liable for any breach or failure of any obligation, representation,
warranty, or covenant made or undertaken by the Trust under this Agreement
except, if such breach or failure is due to any gross negligence or wilful
misconduct of the Trustee.

substantially similar tenor signed by such Holders in person or by an agent duly
appointed in writing; and, except as herein otherwise expressly provided, such
action shall become effective when such instrument or instruments are delivered
to the Trustee and, where it is hereby expressly required, to the Company. Such
instrument or instruments (and the action embodied therein and evidenced
thereby) are herein sometimes referred to as the "Act" of the Holders signing
such instrument or instruments. Proof of execution of any such instrument or of

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

              (c) The Company may, in the circumstances permitted by the Trust
Indenture Act, fix any day as the record date for the purpose of determining the
Holders of Outstanding Convertible Debentures entitled to give, make or take any
request, demand, authorization, direction, notice, consent, waiver or other
action, or to vote on any action, authorized or permitted to be given or taken
by Holders. If not set by the Company prior to the first solicitation of a
Holder made by any Person in respect of any such action, or, in the case of any
such vote, prior to such vote, the record date for any such action or vote shall
be the 30th day (or, if later, the date of the most recent list of Holders
required to be provided pursuant to Section 701) prior to such first
solicitation or vote, as the case may be. With regard to any record date, only
the Holders on such date (or their duly designated proxies) shall be entitled to
give or take, or vote on, the relevant action.

              (d) The ownership of Convertible Debentures shall be proved by the
Security Register.

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

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

SECTION 205.               Notices, Etc., to Trustee and the Company.

Indenture to be made upon, given or furnished to, or filed with,



                                      -14-
<PAGE>   23

              (a) the Trustee by any Holder or by the Company shall be
sufficient for every purpose hereunder if made, given, furnished or filed in
writing to or with the Trustee at its Corporate Trust Office, Attention:
Corporate Trust & Agency Department, or

              (b) the Company by the Trustee or by any Holder shall be
sufficient for every purpose hereunder (unless otherwise herein expressly
provided) if in writing and mailed, first-class postage prepaid, to the Company
addressed to it at the address of its principal office specified in the first
paragraph of this instrument or at any other address previously furnished in
writing to the Trustee by the Company.

SECTION 206.               Notice to Holders; Waiver.

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

              In case by reason of the suspension of regular mail service or by
reason of any other cause it shall be impracticable to give such notice by mail,
then such notification as shall be made with the approval of the Trustee shall
constitute a sufficient notification for every purpose hereunder.

SECTION 207.               Conflict with Trust Indenture Act.

              If any provision hereof limits, qualifies or conflicts with a
provision of the Trust Indenture Act that is required under such Act to be a
part of and govern this Indenture, the latter provision shall control. If any
provision of this Indenture modifies or excludes any provision of the Trust
Indenture Act that may be so modified or excluded, the latter provision shall be
deemed to apply to this Indenture as so modified or to be excluded, as the case
may be.

              In case any provision in this Indenture or in the Convertible

and enforceability of the remaining provisions shall not in any way be affected
or impaired thereby.

SECTION 211.               Benefits of Indenture.

              Nothing in this Indenture or in the Convertible Debentures,
express or implied, shall give to any Person, other than the parties hereto and
their successors hereunder, the holders of Senior Indebtedness, the holders of
Preferred Securities (to the extent provided herein) and the Holders of
Convertible Debentures, any benefit or any legal or equitable right, remedy or
claim under this Indenture.

SECTION 212.               Governing Law.

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

SECTION 213.               Legal Holidays.

              In any case where any Interest Payment Date, Redemption Date or
Stated Maturity of any Convertible Debenture or the last date on which a Holder
has the right to convert his Convertible Debentures shall not be a Business Day,
then (notwithstanding any other provision of this Indenture or of the
Convertible Debentures) payment of interest or principal or conversion of the
Convertible Debentures need not be made on such date, but may be made on the
next succeeding Business Day (except that, if such Business Day is in the next
succeeding calendar year, such Interest Payment Date, Redemption Date or Stated
Maturity, as the case may be, shall be the immediately preceding Business Day)
with the same force and effect as if made on the Interest Payment Date or
Redemption Date, or at the Stated Maturity or on such last day for conversion,
provided, that no interest shall accrue for the period from and after such
Interest Payment Date, Redemption Date or Stated Maturity, as the case may be.

                           Convertible Debenture Forms

SECTION 401.               Forms Generally.

              The Convertible Debentures and the Trustee's certificate of
authentication shall be substantially in the form of Exhibit A, which is hereby
incorporated in and expressly made a part of this Indenture. The Convertible
Debentures may have letters, numbers, notations or other marks of identification
or designation and such legends or endorsements required by law, stock exchange
rule, agreements to which the Company is subject, if any, or usage (provided
that any such notation, legend or endorsement is in a form acceptable to the
Company). The Company shall furnish any such legend not contained in Exhibit A
to the Trustee in writing. Each Convertible Debenture shall be dated the date of
its authentication. The terms and provisions of the Convertible Debentures set
forth in Exhibit A are part of the terms of this Indenture and to the extent
applicable, the Company and the Trustee, by their execution and delivery of this
Indenture, expressly agree to such terms and provisions and to be bound
thereby.

              The definitive Convertible Debentures shall be typewritten or
printed, lithographed or engraved or produced by any combination of these
methods on steel engraved borders or may be produced in any other manner
permitted by the rules of any securities exchange on which the Convertible
Debentures may be listed, all as determined by the officers executing such
Convertible Debentures, as evidenced by their execution thereof.

SECTION 402.               Initial Issuance to Property Trustee.

              The Convertible Debentures initially issued to the Property
Trustee of the Trust shall be in the form of one or more individual certificates
in definitive, fully registered form without coupons and shall bear the
following legend (the "Restricted Securities Legend") unless the Company
determines otherwise in accordance with applicable law.

                                   ARTICLE VI

                           The Convertible Debentures

SECTION 601.               Title and Terms.

              The aggregate principal amount of Convertible Debentures that may
be authenticated and delivered under this Indenture is limited to $103,092,775
(or up to $113,402,050 if the over-allotment option is exercised by the Trust in
accordance with the terms and provisions of the Purchase Agreement), except for
Convertible Debentures authenticated and delivered upon registration of transfer
of, or in exchange for, or in lieu of, other Convertible Debentures pursuant to
Section 304, 305, 306, 906, 1109 or 1301.

              The Convertible Debentures shall be known and designated as the "5
1/4% Convertible Subordinated Debentures Due 2028" of the Company. Their Stated
Maturity shall be April 1, 2028, and they shall bear interest at the rate of 5
1/4% per annum, from March 13, 1998 or from the most recent Interest Payment
Date to which interest has been paid or duly provided for, as the case may be,
payable quarterly (subject to deferral as set forth herein), in arrears, on
January 1, April 1, July 1, October 1 (each an "Interest Payment Date") of each
year, commencing July 1, 1998, until the principal thereof is paid or made
available for payment, and they shall be paid to the Person in whose name the
Convertible Debenture is registered at 5:00 p.m. (New York City time) on the
regular record date for such interest installment, which shall be the March 15,
June 15, September 15 and December 15 next preceding such Interest Payment Date
(the "Regular Record Date"). Interest will compound quarterly and will accrue at
the rate of 5 1/4% per annum on any interest installment in arrears for more
than one quarter or during an extension of an interest payment period as set
forth in Section 312 hereof.

              The amount of interest payable for any period will be computed on
the basis of a 360-day year of twelve 30-day months. Except as provided in the
following sentence, the amount of interest payable for any period shorter than a
full quarterly period for which interest in computed, will be computed on the
basis of the actual number of days elapsed per 90-day quarter. In the event that
any date on which interest is payable on the Convertible Debentures is not a
Business Day, then payment of interest payable on such date will be made on the
next succeeding day which is a Business Day (and without any interest or other
payment in respect of any such delay), except that, if such Business Day is in
the next succeeding calendar year, such payment shall be made on the immediately
preceding Business Day, in each case with the same force and effect as if made
on such date.

              If at any time while the Property Trustee is the Holder of any
Convertible Debentures, the Trust or the Property Trustee is required to pay any
taxes, duties, assessments or governmental charges of whatever nature (other
than withholding taxes) imposed by the United States, or any other taxing
authority, then, in any such case, the Company will pay as additional interest
("Additional Interest") on the Convertible




                                      -19-
<PAGE>   28
 
Debentures held by the Property Trustee, such amounts as shall be required so
that the net amounts received and retained by the Trust and the Property Trustee
after paying any such taxes, duties, assessments or other governmental charges
will be not less than the amounts the Trust and the Property Trustee would have
received had no such taxes, duties, assessments or other governmental charges
been imposed.

              The principal of and interest on the Convertible Debentures shall
be payable at the office or agency of the Company in the United States
maintained for such purpose and at any other office or agency maintained by the
Company for such purpose in such coin or currency of the United States of
America as at the time of payment is legal tender for payment of public and
private debts; provided, however, that at the option of the Company payment of
interest may be made by check mailed to the address of the Person entitled
thereto as such address shall appear in the Security Register.

              The Convertible Debentures shall be redeemable as provided in
Article Eleven hereof.

              The Convertible Debentures shall be subordinated in right of
payment to Senior Indebtedness as provided in Article Twelve hereof.

              The Convertible Debentures shall be convertible as provided in
Article Thirteen hereof.

SECTION 602.               Denominations.

              The Convertible Debentures shall be issuable only in registered
form without coupons and only in denominations of $25 and integral multiples
thereof.

SECTION 603.               Execution, Authentication, Delivery and Dating.

              The Convertible Debentures shall be executed on behalf of the
Company by its Chairman of the Board, its Vice Chairman of the Board, its Chief
Executive Officer, its President or one of its Vice Presidents, under its
corporate seal reproduced thereon attested by its Secretary or one of its
Assistant Secretaries. The signature of any of these officers on the Convertible
Debentures may be manual or facsimile.

              Convertible Debentures 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
Convertible Debentures or did not hold such offices at the date of such
Convertible Debentures.

              At any time and from time to time after the execution and delivery
of this Indenture, the Company may deliver Convertible Debentures executed by
the Company to the Trustee for authentication, together with a Company Order for
the authentication 



                                      -20-
<PAGE>   29
and delivery of such Convertible Debentures; and the Trustee in accordance with
such Company Order shall authenticate and make available for delivery such
Convertible Debentures as in this Indenture provided and not otherwise.

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

SECTION 604.               Temporary Convertible Debentures.

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

              If temporary Convertible Debentures are issued, the Company will
cause definitive Convertible Debentures to be prepared without unreasonable
delay. After the preparation of definitive Convertible Debentures, the temporary
Convertible Debentures shall be exchangeable for definitive Convertible
Debentures upon surrender of the temporary Convertible Debentures at any office
or agency of the Company designated pursuant to Section 1002, without charge to
the Holder. Upon surrender for cancellation of any one or more temporary
Convertible Debentures the Company shall execute and the Trustee shall
authenticate and make available for delivery in exchange therefor a like
principal amount of definitive Convertible Debentures of authorized
denominations. Until so exchanged the temporary Convertible Debentures shall in
all respects be entitled to the same benefits under this Indenture as definitive
Convertible Debentures.

SECTION 605.               Registration, Registration of Transfer and Exchange.

              The Company shall cause to be kept at the Corporate Trust Office
of the Trustee a register (the register maintained in such office and in any
other office or agency designated pursuant to Section 1002 being herein
sometimes collectively referred to as the "Security Register") in which, subject
to such reasonable regulations as it may prescribe, the Company shall provide
for the registration of Convertible Debentures and of transfers of Convertible
Debentures. The Trustee is hereby appointed "Security Registrar" for the purpose
of registering Convertible Debentures and transfers of Convertible Debentures
as herein provided.



                                      -21-
<PAGE>   30

              Upon surrender for registration of transfer of any Convertible
Debenture at an office or agency of the Company designated pursuant to Section
1002 for such purpose, the Company shall execute, and the Trustee shall
authenticate and deliver, in the name of the designated transferee or
transferees, one or more new Convertible Debentures of any authorized
denominations and of a like aggregate principal amount.

              At the option of the Holder, Convertible Debentures may be
exchanged for other Convertible Debentures of any authorized denominations and
of a like aggregate principal amount, upon surrender of the Convertible
Debentures to be exchanged at such office or agency. Whenever any Convertible
Debentures are so surrendered for exchange, the Company shall execute, and the
Trustee shall authenticate and make available for delivery, the Convertible
Debentures which the Holder making the exchange is entitled to receive.

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

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

              No service charge shall be made for any registration of transfer
or exchange of Convertible Debentures, but the Company may require payment of a
sum sufficient to cover any tax or other governmental charge that may be imposed
in connection with any registration of transfer or exchange of Convertible
Debentures, other than exchanges pursuant to Section 304, 906, 1109 or 1301 not
involving any transfer.

SECTION 606.           Mutilated, Destroyed, Lost and Stolen Convertible
                       Debentures.

              If any mutilated Convertible Debenture is surrendered to the
Trustee, the Company shall execute and the Trustee shall authenticate and
deliver in exchange therefor a new Convertible Debenture of like tenor and
principal amount and bearing a number not contemporaneously outstanding.

              If there shall be delivered to the Company and the Trustee (i)
evidence to their satisfaction of the destruction, loss or theft of any
Convertible Debenture and (ii) such Convertible Debenture or indemnity as may be
required by them to save each of them and any agent of either of them harmless,
then, in the absence of notice to the Company or the Trustee that such
Convertible Debenture has been acquired by a bona fide purchaser, the Company
shall execute and the Trustee shall authenticate and deliver, in lieu of any
such




                                      -22-
<PAGE>   31

destroyed, lost or stolen Convertible Debenture, a new Convertible Debenture of
like tenor and principal amount and bearing a number not contemporaneously
outstanding.

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

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

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

SECTION 607.               Payment of Interest; Interest Rights Preserved.

              Interest on any Convertible Debenture which is payable, and is
punctually paid or duly provided for, on any Interest Payment Date shall be paid
to the Person in whose name that Convertible Debenture (or one or more
Predecessor Securities) is registered at 5:00 p.m. (New York City time) on the
Regular Record Date.

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

              (a) The Company may elect to make payment of any Defaulted
Interest to the Persons in whose names the Convertible Debentures (or their
respective Predecessor Securities) are registered at 5:00 p.m. (New York City
time) on a Special Record Date for the payment of such Defaulted Interest, which
shall be fixed in the following manner. The Company shall notify the Trustee in
writing of the amount of Defaulted Interest proposed to be paid on each
Convertible Debenture and the date of the proposed payment, and at the same
time the Company shall deposit with the Trustee an amount of money equal to the
aggregate amount proposed to be paid in respect of such Defaulted Interest or
shall make



                                      -23-
<PAGE>   32

arrangements satisfactory to the Trustee for such deposit prior to the date of
the proposed payment, such money when deposited to be held in trust for the
benefit of the Persons entitled to such Defaulted Interest as in this Clause (a)
provided. Thereupon the Trustee shall fix a Special Record Date for the payment
of such Defaulted Interest which shall be not more than 15 days and not less
than 10 days prior to the date of the proposed payment and not less than 10 days
after the receipt by the Trustee of the notice of the proposed payment. The
Trustee shall promptly notify the Company of such Special Record Date and, in
the name and at the expense of the Company, shall cause notice of the proposed
payment of such Defaulted Interest and the Special Record Date therefor to be
mailed, first-class postage prepaid, to each Holder at his address as it appears
in the Security Register, not less than 10 days prior to such Special Record
Date. Notice of the proposed payment of such Defaulted Interest and the Special
Record Date therefor having been so mailed, such Defaulted Interest shall be
paid to the Persons in whose names the Convertible Debentures (or their
respective Predecessor Securities) are registered at 5:00 p.m. (New York City
time) on such Special Record Date and shall no longer be payable pursuant to the
following Clause (b).

              (b) The Company may make payment of any Defaulted Interest in any
other lawful manner not inconsistent with the requirements of any securities
exchange on which the Convertible Debentures may be listed, and, if so listed,
upon such notice as may be required by such exchange, if, after notice given by
the Company to the Trustee of the proposed payment pursuant to this Clause (B),
such manner of payment shall be deemed practicable by the Trustee.

              Subject to the foregoing provisions of this Section 307, each
Convertible Debenture delivered under this Indenture upon registration of
transfer of or in exchange for or in lieu of any other Convertible Debenture
shall carry the rights to interest accrued and unpaid, and to accrue (including
in each such case Additional Payments, if any), which were carried by such other
Convertible Debenture.

              In the case of any Convertible Debenture which is converted after
any Regular Record Date and on or prior to the next succeeding Interest Payment
Date (other than any Convertible Debenture whose Maturity is prior to such
Interest Payment Date), interest whose Stated Maturity is on such Interest
Payment Date shall be payable on such Interest Payment Date notwithstanding such
conversion, and such interest (whether or not punctually paid or duly provided
for) shall be paid to the Person in whose name that Convertible Debenture (or
one or more Predecessor Securities) is registered at 5:00 p.m. (New York City
time) on such Regular Record Date. Except as otherwise expressly provided in the
immediately preceding sentence, in the case of any Convertible Debenture that
is converted prior to any Regular Record Date, interest whose Stated Maturity is
after the date of conversion of such Convertible Debenture shall not be payable,
and the Company shall not make nor be required to make any other payment,
adjustment or allowance with respect to accrued but unpaid interest (including
Additional Payments, if any) on the Convertible Debentures being converted,
which shall be deemed to be paid in full. Subject to any right of the Holder of
such Convertible Debenture or any Predecessor Security to receive interest



                                      -24-
<PAGE>   33

as provided in this paragraph and the second paragraph of Clause (a) of Section
1302, the Company's delivery upon conversion of the fixed number of shares of
Company Common Stock into which the Convertible Debentures are convertible
(together with the cash payment, if any, in lieu of fractional shares) shall be
deemed to satisfy the Company's obligation to pay the principal amount at
Maturity of the portion of Convertible Debentures so converted and any unpaid
interest (including Additional Payments, if any) accrued on such Convertible
Debentures at the time of such conversion. If any Convertible Debenture called
for redemption is converted, any money deposited with the Trustee or with any
Paying Agent or so segregated and held in trust for the redemption of such
Convertible Debenture shall (subject to any right of the Holder of such
Convertible Debenture or any Predecessor Security to receive interest as
provided in this paragraph) be paid to the Company upon Company Request or, if
then held by the Company, shall be discharged from such trust.

SECTION 608.               Persons Deemed Owners.

              Prior to due presentment of a Convertible Debenture for
registration of transfer, the Company, the Trustee and any agent of the Company
or the Trustee may treat the Person in whose name such Convertible Debenture is
registered as the owner of such Convertible Debenture for the purpose of
receiving payment of principal of and (subject to Section 307) interest
(including Additional Payments, if any) on such Convertible Debenture and for
all other purposes whatsoever, whether or not such Convertible Debenture be
overdue, and neither the Company, the Trustee nor any agent of the Company or
the Trustee shall be affected by notice to the contrary.

SECTION 609.               Cancellation.

              All Convertible Debentures surrendered for payment, redemption,
registration of transfer or exchange or conversion shall, if surrendered to any
Person other than the Trustee, be delivered to the Trustee and shall be promptly
cancelled by it. The Company may at any time deliver to the Trustee for
cancellation any Convertible Debentures previously authenticated and delivered
hereunder which the Company may have acquired in any manner whatsoever, and all
Convertible Debentures so delivered shall be promptly cancelled by the Trustee.
No Convertible Debentures shall be authenticated in lieu of or in exchange for
any Convertible Debentures cancelled as provided in this Section, except as
expressly permitted by this Indenture. All cancelled Convertible Debentures held
by the Trustee shall be disposed of as directed by a Company Order; provided,
however, that the Trustee shall not be required to destroy the certificates
representing such cancelled Convertible Debentures.

SECTION 610.               Right of Set Off.

              Notwithstanding anything to the contrary in this Indenture, the
Company shall have the right to set off any payment it is otherwise required to
make hereunder to the extent the Company has theretofore made, or is
concurrently on the date of such payment making, a payment under the Guarantee.



                                      -25-
<PAGE>   34

SECTION 611.               CUSIP Numbers.

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

SECTION 612.               Option to Extend Interest Payment Period.

              (a) Provided that no Event of Default has occurred and is
continuing, the Company shall have the right at any time during the term of the
Convertible Debentures to defer interest payments (including Additional
Payments) from time to time by extending the interest payment period for
successive periods (each, an "Extension Period") not exceeding 20 consecutive
quarters for each such period; provided, no Extension Period may extend beyond
the maturity date of the Convertible Debentures. At the end of each Extension
Period, the Company shall pay all interest then accrued and unpaid (including
Additional Interest) together with interest thereon compounded quarterly at the
rate specified for the Convertible Debentures to the extent permitted by
applicable law ("Compounded Interest"); provided, that during any Extension
Period, the Company shall (i) not declare or pay dividends on, or make a
distribution with respect to, or redeem or purchase or acquire, or make a
liquidation payment with respect to, any of its capital stock (other than (A)
purchases or acquisitions of shares of Company Common Stock in connection with
the satisfaction by the Company of its obligations under any employee benefit
plans or the satisfaction by the Company of its obligations pursuant to any
contract or security requiring the Company to purchase shares of Company Common
Stock, (B) as a result of a reclassification of the Company's capital stock or
the exchange or conversion of one class or series of the Company's capital stock
for another class or series of the Company's capital stock or (C) the purchase
of fractional interests in shares of the Company's capital stock pursuant to the
conversion or exchange provisions of such capital stock or the security being
converted or exchanged) or make any guarantee payments with respect to the
foregoing, (ii) not make any payment of interest, principal or premium, if any,
on or repay, repurchase or redeem any debt securities (including guarantees)
issued by the Company that rank pari passu with or junior to the Convertible
Debentures (except by conversion into or exchange for shares of its capital
stock) and (iii) not make any guarantee payments with respect to the foregoing
(other than pursuant to the Guarantee). Prior to the termination of any such
Extension Period, the Company may further extend such Extension Period;
provided, that such Extension Period, together with all such previous and
further extensions thereof, may not exceed 20 consecutive quarters or extend
beyond the maturity date of the Convertible Debentures. Upon the termination of
any Extension Period and the payment of all amounts then due, the



                                      -26-
<PAGE>   35

Company may commence a new Extension Period, subject to the above requirements.
No interest during an Extension Period, except at the end thereof, shall be due
and payable. Notwithstanding any other provision in this Indenture to the
contrary, the Company shall not have the right at any time to defer any
Additional Interest, including by extending the interest payment period.

              (b) If the Property Trustee is the sole Holder of the Convertible
Debentures at the time the Company selects an Extension Period, the Company

applicable self-regulatory organization or to holders of the Preferred
Securities of the record date or the date such distributions are payable, but in
any event not less than 10 Business Days prior to such record date. The Company

SECTION 613.              Paying Agent, Security Registrar and Conversion Agent.

              The Trustee will initially act as Paying Agent, Security Registrar
and Conversion Agent. The Company may change any Paying Agent, Security

SECTION 314.               Global Security.

              (a) In connection with a Dissolution Event,




                                      -27-
<PAGE>   36




                           (1)  the Convertible Debentures in certificated form
may be presented to the Trustee by the Property Trustee in exchange for a global
Convertible Debenture in an aggregate principal amount equal to the aggregate
principal amount of all outstanding Convertible Debentures (a "Global
Security"), to be registered in the name of the Depositary, or its nominee, and
delivered by the Trustee to the Depositary for crediting to the accounts of its
participants pursuant to the instructions of the Administrative Trustees. The
Company upon any such presentation shall execute a Global Security in such
aggregate principal amount and deliver the same to the Trustee for
authentication and delivery in accordance with this Indenture. Payments on the
Convertible Debentures issued as a Global Security will be made to the
Depositary; and

                           (2)  if any Preferred Securities are held in non
book-entry certificated form, the Convertible Debentures in certificated form
may be presented to the Trustee by the Property Trustee and any Preferred
Security Certificate which represents Preferred Securities other than Preferred
Securities held by the Depositary or its nominee ("Non Book-Entry Preferred
Securities") will be deemed to represent beneficial interests in Convertible
Debentures presented to the Trustee by the Property Trustee having an aggregate
principal amount equal to the aggregate liquidation amount of the Non Book-Entry
Preferred Securities until such Preferred Security Certificates are presented to
the Security Registrar for transfer or reissuance at which time such Preferred
Security Certificates will be cancelled and a Convertible Debenture, registered
in the name of the holder of the Preferred Security Certificate or the
transferee of the holder of such Preferred Security Certificate, as the case may
be, with an aggregate principal amount equal to the aggregate liquidation amount
of the Preferred Security Certificate cancelled, will be executed by the Company
and delivered to the Trustee for authentication and delivery in accordance with
this Indenture. On issue of such Convertible Debentures, Convertible Debentures
with an equivalent aggregate principal amount that were presented by the
Property Trustee to the Trustee will be deemed to have been cancelled.

                  (b) A Global Security may be transferred, in whole but not in
part, only to another nominee of the Depositary, or to a nominee of such
successor Depositary.

                  (c) If (i) the Depositary notifies the Company that it is
unwilling or unable to continue as a depositary for such Global Security and no
successor depositary shall have been appointed, (ii) the Depositary, at any
time, ceases to be a clearing agency registered under the Exchange Act at which
time the Depositary is required to be so registered to act as such depositary
and no successor depositary shall have been appointed, (iii) the Company, in
its sole discretion, determines that such Global Security shall be so
exchangeable or (iv) there shall have occurred an Event of Default with respect
to such Convertible Debentures, as the case may be, the Company will execute,
and, subject to Article Three of this Indenture, the Trustee, upon written
notice from the Company and receipt of a Company Order, will authenticate and
deliver the Convertible Debentures in definitive registered form without
coupons, in authorized denominations, and in an aggregate principal amount equal
to the principal amount of the Global Security in exchange for such Global
Security. In addition,



                                      -28-
<PAGE>   37

upon an Event of Default or if the Company may at any time determine that the
Convertible Debentures shall no longer be represented by a Global Security, in
such event the Company will execute, and subject to Section 305 of this
Indenture, the Trustee, upon receipt of an Officers' Certificate evidencing such
determination by the Company, will authenticate and make available for delivery
the Convertible Debentures in definitive registered form without coupons, in
authorized denominations, and in an aggregate principal amount equal to the
principal amount of the Global Security in exchange for such Global Security.
Upon the exchange of the Global Security for such Convertible Debentures in
definitive registered form without coupons, in authorized denominations, the
Global Security shall be cancelled by the Trustee. Such Convertible Debentures
in definitive registered form issued in exchange for the Global Security shall
be registered in such names and in such authorized denominations as the
Depositary, pursuant to instructions from its direct or indirect participants or
otherwise, shall instruct the Trustee. The Trustee shall deliver such
Convertible Debentures to the Depositary for delivery to the Persons in whose
names such Convertible Debentures are so registered.

              (d) Every Global Security authenticated and delivered hereunder
shall bear a legend in substantially the following form, in capital letters and
bold-face type:

         THIS CONVERTIBLE DEBENTURE IS A GLOBAL SECURITY WITHIN THE MEANING OF
         THE INDENTURE HEREINAFTER REFERRED TO AND IS REGISTERED IN THE NAME OF
         A DEPOSITARY OR A NOMINEE THEREOF. THIS CONVERTIBLE DEBENTURE MAY NOT
         BE EXCHANGED IN WHOLE OR IN PART FOR A CONVERTIBLE DEBENTURE
         REGISTERED, AND NO TRANSFER OF THIS CONVERTIBLE DEBENTURE IN WHOLE OR
         IN PART MAY BE REGISTERED, IN THE NAME OF ANY PERSON OTHER THAN SUCH
         DEPOSITARY OR A NOMINEE THEREOF, EXCEPT IN THE LIMITED CIRCUMSTANCES
         DESCRIBED IN THE INDENTURE.

              (e) If the Depositary is the Depository Trust Company, the Global
Security authenticated and delivered hereunder shall also bear a legend in
substantially the following form, in capital letters and bold-face type:

         UNLESS THIS CERTIFICATE IS PRESENTED BY AN AUTHORIZED SIGNATORY OF THE
         DEPOSITORY TRUST COMPANY ("DTC") TO THE COMPANY OR ITS AGENT FOR
         REGISTRATION OF TRANSFER, EXCHANGE, OR PAYMENT, AND ANY CERTIFICATE
         ISSUED IS REGISTERED IN THE NAME OF CEDE & CO. OR IN SUCH OTHER NAME AS
         IS REQUESTED BY AN AUTHORIZED

      OTHER ENTITY AS IS REQUESTED BY AN AUTHORIZED REPRESENTATIVE OF DTC), ANY

      PERSON IS WRONGFUL INASMUCH AS THE REGISTERED OWNER HEREOF, CEDE & CO.,
      HAS AN INTEREST HEREIN.

              (f) The Convertible Debentures may not be transferred except in
compliance with the Restricted Securities Legend unless otherwise determined by
the Company in accordance with applicable law. Upon any distribution of the
Convertible Debentures to the holders of the Preferred Securities in accordance
with the Trust Agreement, the Company and the Trustee shall enter into a
supplemental indenture pursuant to Section 901(e) to provide for transfer
procedures and restrictions with respect to the Convertible Debentures
substantially similar to those contained in the Trust Agreement to the extent
applicable in the circumstances existing at the time of such distribution.

         delivered to the Trustee for cancellation have become due and payable,
         and the Company has deposited or caused to be deposited with the
         Trustee as trust funds in trust for the purpose an amount sufficient to

interest for whose payment such money has been deposited with the Trustee. All
moneys deposited with the Trustee pursuant to Section 401 (and held by it or any

Trustee if given by Holders), and upon any such declaration such principal and
all accrued interest shall become immediately due and payable.

                  At any time after such a declaration of acceleration has been
made and before a judgment or decree for payment of the money due has been
obtained by the Trustee as provided in this Article, the Holders of a majority

written notice to the Company and the Trustee, may rescind and annul such

         acceleration and interest thereon at the rate borne by the Convertible

         hereunder and the reasonable compensation, expenses, disbursements and
         advances of the

         Trustee, its agents and counsel; 

         and

                  (b) all Events of Default, other than the non-payment of the
principal of Convertible Debentures which have become due solely by such
declaration of acceleration, have been cured or waived as provided in Section
513.

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

SECTION 1003.         Collection of Indebtedness and Suits for Enforcement by 
                      Trustee.

                  The Company covenants that if:

                  (a) default is made in the payment of any interest (including
Additional Payments, if any) on any Convertible Debenture when such interest
becomes due and payable and such default continues for a period of 30 days, or

                  (b) default is made in the payment of the principal of any 
Convertible Debenture at the Maturity thereof,

the Company will, upon demand of the Trustee, pay to it, for the benefit of the
Holders of such Convertible Debentures, the whole amount then due and payable on
such Convertible Debentures for principal and interest (including Additional
Payments, if any) and, to the extent that payment thereof shall be legally
enforceable, interest on any overdue principal and on any overdue interest
(including Additional Payments, if any), at the rate borne by the Convertible
Debentures, and, in addition thereto, such further amount as shall be sufficient
to cover the costs and expenses of collection, including the reasonable
compensation, expenses, disbursements and advances of the Trustee, its agents
and counsel.

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

SECTION 1004.               Trustee May File Proofs of Claim.

creditors, the Trustee shall be entitled and empowered, by intervention in such
proceeding or otherwise, to take any and all actions authorized under the Trust
Indenture Act in order to have claims of the Holders and

authorized to collect and receive any moneys or other property payable or
deliverable on any such claims and to distribute the same; and any custodian,
receiver, assignee, trustee, liquidator, sequestrator or other similar official
in any such judicial proceeding is hereby authorized by each Holder to make such
payments to the Trustee and, in the event that the Trustee shall consent to the
making of such payments directly to the Holders, to pay to the Trustee any
amount due it for the reasonable compensation, expenses, disbursements and
advances of the Trustee, its agents and counsel, and any other amounts due the
Trustee under Section 607.

                  No provision of this Indenture shall be deemed to authorize
the Trustee to authorize or consent to or accept or adopt on behalf of any
Holder any plan of reorganization, arrangement, adjustment or composition
affecting the Convertible Debentures or the rights of any Holder thereof or to
authorize the Trustee to vote in respect of the claim of any Holder in any such
proceeding.

SECTION 1005.       Trustee May Enforce Claims Without Possession of Convertible
                    Debentures.

proceeding relating thereto, and any such proceeding instituted by the Trustee
shall be brought in its own name as trustee of an express trust, and any
recovery of judgment shall, after provision for the payment of the reasonable
compensation, expenses, disbursements and advances of the Trustee, its agents
and counsel, be for the ratable benefit of the Holders of the Convertible
Debentures in respect of which such judgment has been recovered.

payment if only partially paid and upon surrender thereof if fully paid:

Trustee of a continuing Event of Default;

name as Trustee hereunder;

                  (c) such Holder or Holders have offered to the Trustee

right in any manner whatever by virtue of, or by availing of, any provision of
this Indenture to affect, disturb or prejudice the rights of any other Holders,

SECTION 1009.              Restoration of Rights and Remedies.

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

SECTION 1010.              Rights and Remedies Cumulative.

                  Except as otherwise provided with respect to the replacement
or payment of mutilated, destroyed, lost or stolen Convertible Debentures in the
last paragraph of Section 306, no right or remedy herein conferred upon or
reserved to the Trustee or to the Holders is intended to be exclusive of any
other right or remedy, and every right and remedy shall, to the extent permitted
by law, be cumulative and in addition to every other right and remedy given
hereunder or now or hereafter existing at law or in equity or otherwise. The
assertion or employment of any right or remedy hereunder, or otherwise, shall
not prevent the concurrent assertion or employment of any other appropriate
right or remedy.

SECTION 1011.              Delay or Omission Not Waiver.

                  No delay or omission of the Trustee or of any Holder of any

Default shall impair any such right or remedy or constitute a waiver of any such
Event of Default or an acquiescence therein. Every right and remedy given by
this Article or by law to the Trustee or to the Holders may be exercised from
time to time, and as often as may be deemed expedient, by the Trustee or by the
Holders, as the case may be.

method and place of conducting any proceeding for any remedy available to the
Trustee or exercising any trust or power conferred on the Trustee; provided,
that

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

                  (b) the Trustee may take any other action deemed proper by the
Trustee which is not inconsistent with such direction.

SECTION 1013.              Waiver of Past Defaults.

<PAGE>   47



                  Subject to Section 902 hereof, the Holders of not less than a
majority in principal amount of the Outstanding Convertible Debentures may on
behalf of the Holders of all the Convertible Debentures waive any past default
hereunder and its consequences, except a default

                  (a) in the payment of the principal of, premium, if any, or
interest (including Additional Payments, if any) on any Convertible Debenture
(unless such default has been cured and a sum sufficient to pay all matured
installments of interest and principal due otherwise than by acceleration has
been deposited with the Trustee); or

                  (b) in respect of a covenant or provision hereof that under
Article Nine cannot be modified or amended without the consent of the Holder of
each Outstanding Security affected; provided, however, that if the Convertible
Debentures are held by the Trust or a trustee of the Trust, such waiver shall
not be effective until the holders of a majority in liquidation amount of Trust
Securities shall have consented to such waiver; provided, further, that if the
consent of the Holder of each outstanding Convertible Debenture is required,
such waiver shall not be effective until each holder of the Trust Securities
shall have consented to such waiver.

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

SECTION 1014.              Undertaking for Costs.

                  In any suit for the enforcement of any right or remedy under
this Inden ture, or in any suit against the Trustee for any action taken,
suffered or omitted by it as Trustee, a court may require any party litigant in
such suit to file an undertaking to pay the costs of such suit, and may assess
costs against any such party litigant, in the manner and to the extent provided
in the Trust Indenture Act; provided, that neither this Section nor the Trust
Indenture Act shall be deemed to authorize any court to require such an
undertaking or to make such an assessment in any suit instituted by the Company
or the Trustee or in any suit for the enforcement of the right to receive the
principal of and interest (including Additional Payments, if any) on any
Convertible Debenture or to convert any Convertible Debenture in accordance with
Article Thirteen.

SECTION 1015.              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 Indenture; and the 


                                      -39-


<PAGE>   48


Company (to the extent that it may lawfully do so) hereby expressly waives all
benefit or advantage of any such law and covenants that it will not hinder,
delay or impede the execution of any power herein granted to the Trustee, but
will suffer and permit the execution of every such power as though no such law
had been enacted.

SECTION 1016.              Enforcement by Holders of Preferred Securities.

                  Notwithstanding the foregoing, if an Event of Default has
occurred and is continuing and such event is attributable to the failure of the
Company to pay interest or principal on the Convertible Debentures on the date
such interest or principal is otherwise payable, the Company acknowledges that,
in such event, a holder of Preferred Securities may institute a Direct Action
for payment on or after the respective due date specified in the Convertible
Debentures. The Company may not amend this Indenture to remove the foregoing
right to bring a Direct Action without the prior written consent of all the
holders of Preferred Securities. Notwithstanding any payment made to such holder
of Preferred Securities by the Company in connection with a Direct Action, the
Company shall remain obligated to pay the principal of and interest on the
Convertible Debentures (including Additional Payments, if any) held by the Trust
or the Property Trustee and the Company shall be subrogated to the rights of the
holder of such Preferred Securities with respect to payments on the Preferred
Securities to the extent of any payments made by the Company to such holder in
any Direct Action. The holders of Preferred Securities will not be able to
exercise directly any other remedy available to the Holders of the Convert ible
Debentures.

of the rights or powers vested in it by this Indenture at the request or
direction of any of the Holders pursuant to this Indenture, unless such Holders
shall have offered to the Trustee reasonable security or indemnity against the
costs, expenses and liabilities which might be incurred by it in compliance with
such request or direction;

                  (f) the Trustee shall not be bound to make any investigation
into the facts or matters stated in any resolution, certificate, statement,
instrument, opinion, report, notice, request, direction, consent, order, bond,
debenture, note, other evidence of indebtedness or other paper or document, but
the Trustee, in its discretion, may make such further inquiry or investigation
into such facts or matters as it may see fit, and, if the Trustee shall
determine to make such further inquiry or investigation, it shall be entitled to
reasonable examination of the books, records and premises of the Company,
personally or by agent or attorney;

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

                  (h) the Trustee shall not be liable for any action taken,
suffered, or omitted to be taken by it in good faith, without gross negligence
or wilful misconduct, and reasonably believed by it to be authorized or within
the discretion or rights or powers conferred upon it by this Indenture.

SECTION 1204.              Not Responsible for Recitals or Issuance of 
                           Convertible Debentures.

                  The recitals contained herein and in the Convertible
Debentures, except the Trustee's certificates of authentication, shall be taken
as the statements of the Company, and the Trustee assumes no responsibility for
their correctness. The Trustee makes no representations as to the validity or
sufficiency of this Indenture or of the Convertible Debentures. The Trustee
shall not be accountable for the use or application by the Company of the
Convertible Debentures or the proceeds thereof.

                  The Trustee, any Paying Agent, any Security Registrar or any
other agent of the Company, in its individual or any other capacity, may become
the owner or pledgee of Convertible Debentures and, subject to Sections 608 and
613, may otherwise deal with the Company with the same rights it would have if
it were not Trustee, Paying Agent, Security Registrar, or such other agent.

SECTION 1206.              Money Held in Trust.

                  Money held by the Trustee in trust hereunder need not be

SECTION 1207.              Compensation and Reimbursement.

                  The Company agrees

as the Company and the Trustee shall from time to time agree in writing for all

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

                  (c) to indemnify the Trustee and any predecessor Trustee for,
and to hold it harmless against, any loss, liability or expense incurred without
gross negligence or bad faith on its part, arising out of or in connection with
the acceptance or administration of this trust, including the costs and expenses

himself and all others similarly situated, petition any court of competent
jurisdiction for the removal of the Trustee and the appointment of a successor
Trustee.

                  (e)      If the Trustee shall resign, be removed or become
incapable of acting, or if a vacancy shall occur in the office of Trustee for

have been authenticated, but not delivered, by the Trustee then in office, any
successor by merger, conversion or consolidation to such authenticating Trustee
may adopt such authentication and deliver the Convertible Debentures so
authenticated with the same effect as if such successor Trustee had itself
authenticated such Convertible Debentures.

SECTION 1213.              Preferential Collection of Claims Against Company.

                  If and when the Trustee shall be or become a creditor of the

time, may enter into one or more indentures supplemental hereto, in form
satisfactory to the Trustee, for any of the following purposes:

                  (a)  to evidence the succession of another Person to the 
Company and the assumption by any such successor of the covenants of the Company
herein and in the Convertible Debentures; or

                  (b)  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

                  (d)  to cure any ambiguity, to correct or supplement any
provision herein which may be inconsistent with any other provision herein, or
to make any other provi sions with respect to matters or questions arising under
this Indenture which shall not be inconsistent with the provisions of this
Indenture; provided, that such action pursuant to this Clause (d) shall not
adversely affect the interests of the Holders of the Convertible Debentures or,
so long as any of the Preferred Securities shall remain outstanding, the holders
of the Preferred Securities;

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

to make provision for transfer procedures, certification, book-entry provisions,

                  With the consent of the Holders of not less than a majority in
principal amount of the Outstanding Convertible Debentures, by Act of said
Holders delivered to the Company and the Trustee, the Company, when authorized
by a Board Resolution, and the 


                                      -51-

Trustee may enter into an indenture or indentures supplemental hereto for the
purpose of adding any provisions to or changing in any manner or eliminating any
of the provi sions of this Indenture or of modifying in any manner the rights of
the Holders under this Indenture; provided, however, that no such supplemental
indenture shall, without the consent of the Holder of each Outstanding Security
affected thereby,

                  (a) extend the Stated Maturity of the principal of, or any
installment of interest (including Additional Payments, if any) on, any
Convertible Debenture, or reduce the principal amount thereof, or reduce the
rate or extend the time for payment of interest thereon, or extend the Extension
Period, or reduce any premium payable upon the redemption thereof, or change the
place of payment where, or the coin or currency in which, any Convertible
Debenture or interest thereon is payable, or impair the right to institute suit
for the enforcement of any such payment on or after the Stated Maturity thereof
(or, in the case of redemption, on or after the Redemption Date), or adversely
affect the right to convert any Convertible Debenture as provided in Article
Thirteen (except as permitted by Section 901(c)), or modify the provisions of
this Indenture with respect to the subordination of the Convertible Debentures
in a manner adverse to the Holders,

reduce the percentage in principal amount of the Outstanding Convertible

of the provisions of this Section or Section 513, except to increase any such
percentage or to provide that certain other provisions of this Indenture cannot
be modified or waived without the consent of the Holder of each Outstanding
Security affected thereby;

provided that if the Convertible Debentures are held by the Trust or a trustee
of the Trust, such supplemental indenture shall not be effective until the
holders of a majority in liquidation amount of Trust Securities shall have
consented to such supplemental indenture; provided, further, that if the consent
of the Holder of each Outstanding Security is required, such supplemental
indenture shall not be effective until each holder of the Trust Securities of
the Trust shall have consented to such supplemental indenture.

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

                  The Company may, but shall not be obligated to, fix a record
date for the purpose of determining the Persons entitled to consent to any
indenture supplemental hereto. If a record date is fixed, the Holders on such
record date, or their duly designated proxies, and only such Persons, shall be
entitled to consent to such supplemental inden ture, whether or not such Holders
remain Holders after such record date; provided that unless such consent shall
have become effective by virtue of the requisite percentage having been obtained
prior 


                                      -52-


<PAGE>   61
 

to the date which is 90 days after such record date, any such consent previously
given shall automatically and without further action by any Holder be cancelled
and of no further effect.

SECTION 1803.              Execution of Supplemental Indentures.

                  In executing, or accepting the additional trusts created by,
any supplemental indenture permitted by this Article or the modifications
thereby of the trusts created by this Indenture, the Trustee shall be entitled
to receive, and (subject to Section 601) shall be fully protected in relying
upon, an Opinion of Counsel stating that the execution of such supplemental
indenture is authorized or permitted by this Indenture. The Trustee may, but
shall not be obligated to, enter into any such supplemental indenture which
affects the Trustee's own rights, duties or immunities under this Indenture or
otherwise.

SECTION 1804.              Effect of Supplemental Indentures.

                  Upon the execution of any supplemental indenture under this
Article, this Indenture shall be modified in accordance therewith, and such
supplemental indenture shall form a part of this Indenture for all purposes; and
every Holder of Convertible Debentures theretofore or thereafter authenticated
and delivered hereunder shall be bound thereby. No such supplemental indenture
shall directly or indirectly modify the provisions of Article Twelve in any
manner which might terminate or impair the rights of the Senior Indebtedness
pursuant to such subordination provisions.

SECTION 1805.              Conformity with Trust Indenture Act.

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

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

                    Covenants; Representations and Warranties

SECTION 2001.              Payment of Principal and Interest.

                  The Company will duly and punctually pay the principal of and

SECTION 2002.              Maintenance of Office or Agency.

                  The Company will maintain in the United States an office or
agency where Convertible Debentures may be presented or surrendered for payment,
where Convertible Debentures may be surrendered for registration of transfer or
exchange and where notices and demands to or upon the Company in respect of the
Convertible Debentures and this Indenture may be served. The Company will give
prompt written notice to the Trustee of the location, and any change in the
location, of such office or agency. If at any time the Company shall fail to
maintain any such required office or agency or shall fail to furnish the Trustee
with the address thereof, such presentations, surrenders, notices and demands
may be made or served at the Corporate Trust Office of the Trustee, and the
Company hereby appoints the Trustee as its agent to receive all such
presentations, surrenders, notices and demands.

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

SECTION 2003.              Money for Convertible Debenture Payments to Be Held 
                           in Trust.

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

                  Whenever the Company shall have one or more Paying Agents, it
will, prior to each due date of the principal of or interest on any Convertible
Debentures, deposit with a Paying Agent a sum sufficient to pay such amount,
such sum to be held as provided by the 


                                      -54-

Trust Indenture Act, and (unless such Paying Agent is the Trustee) the Company
will promptly notify the Trustee of its action or failure so to act.

                  The Company will cause each Paying Agent other than the
Trustee to execute and deliver to the Trustee an instrument in which such Paying
Agent shall agree with the Trustee, subject to the provisions of this Section,
that such Paying Agent will (i) comply with the provisions of the Trust
Indenture Act applicable to it as a Paying Agent and (ii) during the continuance
of any default by the Company (or any other obligor upon the Convertible
Debentures) in the making of any payment in respect of the Convertible
Debentures, upon the written request of the Trustee, forthwith pay to the
Trustee all sums held in trust by such Paying Agent as such.

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

                  Any money deposited with the Trustee or any Paying Agent, or
then held by the Company, in trust for the payment of the principal of or
interest on (including Additional Payments, if any) any Convertible Debenture
and remaining unclaimed for two years after such principal or interest has
become due and payable shall be paid to the Company on Company Request, or (if
then held by the Company) shall be discharged from such trust; and the Holder of
any such Convertible Debenture shall thereafter, as an unsecured general
creditor, look only to the Company for payment thereof, and all liability of the
Trustee or such Paying Agent with respect to such trust money, and all liability
of the Company as trustee thereof, shall thereupon cease.

SECTION 2004.              Statement by Officers as to Default.

                  The Company will deliver to the Trustee, within 120 days after
the end of each fiscal year of the Company ending after the date hereof, an
Officers' Certificate, stating whether or not to the best knowledge of the
signers thereof the Company is in default in the performance and observance of
any of the material terms, provisions and conditions of this Indenture (without
regard to any period of grace or requirement of notice provided hereunder) and,
if the Company shall be in default, specifying all such defaults and the nature
and status thereof of which they may have knowledge.

SECTION 2005.              Limitation on Dividends; Covenants as to the Trust.

                  (a) The Company covenants that so long as the Convertible
Debentures are outstanding, if (i) there shall have occurred and be continuing
any event that with the giving 


                                      -55-

of notice or the lapse of time or both, would constitute an Event of Default,
(ii) the Company shall be in default with respect to its payment of any
obligations under the Guarantee, or (iii) the Company has exercised its option
to defer interest payments on the Convertible Debentures by extending the
interest payment period and such period, or any extension thereof, shall be
continuing, then the Company shall (A) not declare or pay dividends on, or make
a distribution with respect to, or redeem or purchase or acquire, or make a
liquidation payment with respect to, any of its capital stock (other than (x)

the satisfaction by the Company of its obligations under any employee benefit
plans or the satisfaction by the Company of its obligations pursuant to any
contract or security requiring the Company to purchase shares of Company Common

the exchange or conversion of one class or series of the Company's capital stock

(other than pursuant to the Guarantee).

                  (b) The Company also covenants and agrees (i) that it shall
directly or indirectly maintain 100% ownership of the Common Securities of the
Trust; provided, however, that any permitted successor of the Company hereunder
may succeed to the Company's ownership of such Common Securities and (ii) that
it shall use its reasonable efforts, consistent with the terms and provisions of
the Trust Agreement, to cause the Trust (x) to remain a statutory business
trust, except in connection with the distribution of the Convertible Debentures
to the holders of Trust Securities in liquidation of the Trust, the redemption
of all of the Trust Securities of the Trust, or certain mergers, consolida tions
or amalgamations, each as permitted by the Trust Agreement, and (y) to otherwise
continue to be classified as a grantor trust for United States Federal income
tax purposes.

SECTION 2006.              Payment of Expenses of the Trust.

                  In connection with the offering, sale and issuance of the

</TABLE>

If the Company has deferred interest payments, all unpaid interest must be paid
in cash prior to redemption. Any redemption pursuant to this Section 1101 shall
be made pursuant to the provisions of Sections 1103 through 1108 hereof.

         (b) If a partial redemption of the Convertible Debentures would result
in the delisting of the Preferred Securities issued by the Trust from any
national securities exchange or other organization on which the Preferred
Securities are listed, the Company shall not be permitted to effect such partial
redemption and may only redeem the Convertible Debentures in whole.

SECTION 2202. Tax Event Optional Redemption.

         If a Tax Event has occurred and is continuing and:

         (a) the Company has received a Redemption Tax Opinion; or

Company shall have the right upon not less than 30 days nor more than 60 days
notice to the Holders of the Convertible Debentures to redeem the Convertible
Debentures in whole (but not in part) for cash at a redemption price equal to
100% of the principal amount of the Convertible Debentures plus accrued and
unpaid interest (including Additional Payments), if any, within 90 days
following the occurrence of such Tax Event (the "90-Day Period"); provided,
however, that if, at the time there is available to the Company or the Trust the
opportunity to eliminate within the 90-Day Period, the Tax Event by taking some
ministerial action ("Ministerial Action"), such as filing a form or making an
election, or pursuing some other similar reasonable measure which, in the sole
judgment of the Company, has or will cause no adverse effect on the Company, the
Trust or the Holders of the Trust Securities and will involve no material cost,
the Company or the Trust shall pursue such Ministerial Action or other measure
in lieu of redemption, and provided, further, that the Company shall have no
right to redeem the Convertible Debentures while the Trust is pursuing any
Ministerial Action or other similar measure pursuant to its obligations under
the Trust Agreement.

SECTION 2203. Applicability of Article.

         Redemption of Convertible Debentures at the election of the Company, as
permitted by Sections 1101 and 1102, shall be made in accordance with such
provision and this Article.

SECTION 2204. Election to Redeem; Notice to Trustee.

         The election of the Company to redeem Convertible Debentures pursuant
to Section 1101 or 1102 shall be evidenced by a Board Resolution. In case of any
redemption at the election of the Company, the Company shall, at least 45 days
and no more than 90 days prior to the Redemption Date fixed by the Company,
notify the Trustee in writing of such Redemption Date and of the principal
amount of Convertible Debentures to be redeemed and provide a copy of the notice
of redemption given to Holders of Convertible Debentures to be redeemed pursuant
to Section 1105.

SECTION 2205. Selection by Trustee of Convertible Debentures to Be Redeemed.

         If less than all the Convertible Debentures are to be redeemed (unless
such redemption affects only a single Convertible Debenture), the particular
Convertible Debentures to be redeemed shall be selected not more than 45 days
prior to the Redemption Date by the Trustee, from the Outstanding Convertible
Debentures not previously called for redemption, by such method as the Trustee
shall deem fair and appropriate and which may provide for the selection for
redemption of portions (equal to $25 or any integral multiple thereof) of the
principal amount of the Convertible Debentures.

         The Trustee shall promptly notify the Company in writing of the
Convertible Debentures selected for redemption as aforesaid and, in case of any
Convertible Debentures selected for partial redemption as aforesaid, the
principal amount thereof to be redeemed.



                                     - 59 -
<PAGE>   68

         The provisions of the two preceding paragraphs shall not apply with
respect to any redemption affecting only a single Convertible Debenture, whether
such Convertible Debenture is to be redeemed in whole or in part. In the case of
any such redemption in part, the unredeemed portion of the principal amount of
the Convertible Debenture shall be in an authorized denomination (which shall
not be less than the minimum authorized denomination) for such Convertible
Debenture.

         For all purposes of this Indenture, unless the context otherwise
requires, all provisions relating to the redemption of Convertible Debentures

redeemed only in part, to the portion of the principal amount of such
Convertible Debentures which has been or is to be redeemed.

address appearing in the Security Register.

         All notices of redemption shall identify the Convertible Debentures to

         (a) the Redemption Date,

         (b) the Redemption Price,

         (c) that on the Redemption Date the Redemption Price will become due

interest thereon will cease to accrue on and after said date, and

         (d) the place or places where such Convertible Debentures are to be
surrendered for payment of the Redemption Price.

         Notice of redemption of Convertible Debentures to be redeemed at the
election of the Company shall be given by the Company or, at the Company's
request, by the Trustee in the name and at the expense of the Company.

SECTION 2207. Deposit and Payment of Redemption Price.

         Prior to 10:00 a.m. (New York City time) on the Redemption Date, the
Company shall deposit with the Trustee or with a Paying Agent (or, if the
Company is acting as its own Paying Agent, segregate and hold in trust as
provided in Section 1003) an amount of money sufficient to pay the Redemption
Price of, plus (except if the Redemption Date shall be an Interest Payment Date)
accrued and unpaid interest (including Additional



                                     - 60 -

Payments, if any) on all the Convertible Debentures which are to be redeemed on
that date. Such redemption payment shall be made to the Holders prior to 12:00
noon (New York City time) on the Redemption Date or such earlier time as the
Company determines.

         If any Convertible Debenture called for redemption is converted, any
money deposited with the Trustee or with any Paying Agent or so segregated and
held in trust for the redemption of such Convertible Debenture shall (subject to
any right of the Holder of such Convertible Debenture or any Predecessor
Security to receive interest as provided in the last paragraph of Section 307)
be paid to the Company upon Company Request or, if then held by the Company,
shall be discharged from such trust.

SECTION 2208. Convertible Debentures Payable on Redemption Date.

         Notice of redemption having been given as aforesaid, the Convertible
Debentures so to be redeemed shall, on the Redemption Date, become due and
payable at the Redemption Price therein specified, and from and after such date
(unless the Company shall default in the payment of the Redemption Price and
accrued and unpaid interest, including Additional Payments, if any) such
Convertible Debentures shall cease to bear interest. Upon surrender of any such
Convertible Debenture for redemption in accordance with said notice, such
Convertible Debenture shall be paid by the Company at the Redemption Price,
together with accrued and unpaid interest (including Additional Payments, if
any) to the Redemption Date; provided, however, that installments of interest
whose Stated Maturity is on or prior to the Redemption Date shall be payable to
the Holders of such Convertible Debentures, or one or more Predecessor
Convertible Debentures, registered as such at 5:00 p.m. (New York City time) on
the relevant Record Dates according to the terms and the provisions of Section
307.

         If any Convertible Debenture called for redemption shall not be so paid
upon surrender thereof for redemption, the principal shall, until paid, bear
interest from the Redemption Date at the rate borne by the Convertible
Debenture.

SECTION 2209. Convertible Debentures Redeemed in Part.

         In the event of any redemption in part, the Company shall not be
required to (i) issue, register the transfer of or exchange any Convertible
Debenture during a period beginning at 9:00 a.m. (New York City time) 15
Business Days before any selection for redemption of Convertible Debentures and
ending at 5:00 p.m. (New York City time) on the earliest date in which the
relevant notice of redemption is deemed to have been given to all holders of
Convertible Debentures to be so redeemed and (ii) register the transfer of or
exchange any Convertible Debentures so selected for redemption, in whole or in
part, except for the unredeemed portion of any Convertible Debentures being
redeemed in part.

         Any Convertible Debenture which is to be redeemed only in part shall be
surrendered at a place of payment therefor (with, if the Company or the Trustee
so requires, 



                                     - 61 -

due endorsement by, or a written instrument of transfer in form satisfactory to
the Company and the Trustee duly executed by, the Holder thereof or his attorney
duly authorized in writing), and the Company shall execute, and the Trustee
shall authenticate and make available for delivery to the Holder of such
Convertible Debenture without service charge, a new Convertible Debenture or
Convertible Debentures, of any authorized denomination as requested by such
Holder, in aggregate principal amount equal to and in exchange for the
unredeemed portion of the principal of the Convertible Debenture so surrendered.

SECTION 2210. No Sinking Fund.

         The Convertible Debentures are not entitled to the benefit of any
sinking fund.

SECTION 2211. Mandatory Redemption.

         Upon (i) repayment at maturity or (ii) as a result of acceleration upon
the occurrence and continuation of an Event of Default, the Company shall redeem

any accrued and unpaid interest, including any Additional Payments, to the date
fixed for redemption. Any payment pursuant to this section shall be made prior

                                  ARTICLE XXIV

                     Subordination of Convertible Debentures

SECTION 2401. Agreement to Subordinate.

         The Company covenants and agrees, and each Holder of Convertible
Debentures by such Holder's acceptance thereof likewise covenants and agrees,
that all Convertible Debentures shall be issued subject to the provisions of
this Article Twelve; and each Holder of a Convertible Debenture, whether upon
original issue or upon transfer or assignment thereof, accepts and agrees to be
bound by such provisions. The payment by the Company of the principal of,
premium, if any, and interest (including Additional Payments, if any) on all
Convertible Debentures issued hereunder shall, to the extent and in the manner
hereinafter set forth, be subordinated and junior in right of payment to the
prior payment in full of all existing and future Senior Indebtedness, whether
outstanding at the date of this Indenture or thereafter incurred; provided
however, that no provision of this Article Twelve shall prevent the occurrence
of any default or Event of Default hereunder.

SECTION 2402. Default on Senior Indebtedness.

         In the event and during the continuation of any default by the Company
in the payment of principal, premium, interest or any other payment due on any
Senior Indebtedness continuing beyond the period of grace, if any, specified in
the instrument evidencing such Senior Indebtedness, unless and until such
default shall have been cured or waived or shall have ceased to exist, and in
the event that the maturity of any Senior Indebtedness has been accelerated
because of a default, then no payment shall be made by the Company with respect
to the principal of (including redemption payments, if any), premium, if any, or
interest on the Convertible Debentures.

         In the event that, notwithstanding the foregoing, any payment shall be
received by the Trustee when such payment is prohibited by the preceding
paragraph of this Section 1202, such payment shall be held in trust for the
benefit of, and shall be paid over or delivered to, the holders of Senior
Indebtedness or their respective representatives, or to the trustee or trustees
under any indenture pursuant to which any of such Senior Indebtedness may have
been issued, as their respective interests may appear, but only to the extent
that the holders of the Senior Indebtedness (or their representative or
representatives or a trustee) notify the Trustee in writing within 90 days of
such payment of the amounts then due and owing on the Senior Indebtedness and
only the amounts specified in such notice to the Trustee shall be paid to the
holders of Senior Indebtedness.

SECTION 2403. Liquidation; Dissolution; Bankruptcy.

         Upon any payment by the Company or distribution of assets of the
Company of any kind or character, whether in cash, property or securities, to
creditors upon any



                                     - 63 -
<PAGE>   72

dissolution or winding up or liquidation or reorganization of the Company,
whether voluntary or involuntary, or in bankruptcy, insolvency, receivership or
other proceedings, all principal of, and premium, if any, and interest due or to
become due on, all Senior Indebtedness must be paid in full before any payment
is made on account of the principal (and premium, if any) or interest (including
Additional Payments, if any) on the Convertible Debentures; and upon any such
dissolution or winding up or liquidation or reorganization, any payment by the
Company, or distribution of assets of the Company of any kind or character,
whether in cash, property or securities, to which the Holders of the Convertible
Debentures or the Trustee would be entitled, except for the provisions of this
Article Twelve, shall be paid by the Company or by any receiver, trustee in
bankruptcy, liquidating trustee, agent or other Person making such payment or
distribution, or by the Holders of the Convertible Debentures or by the Trustee
under this Indenture if received by them or it, directly to the holders of
Senior Indebtedness (pro rata to such holders on the basis of the respective
amounts of Senior Indebtedness held by such holders, as calculated by the
Company) or their representative or representatives, or to the trustee or
trustees under any indenture pursuant to which any instruments evidencing such
Senior Indebtedness may have been issued, as their respective interests may
appear, to the extent necessary to pay such Senior Indebtedness in full, in
money or money's worth, after giving effect to any concurrent payment or
distribution to or for the holders of such Senior Indebtedness, before any
payment or distribution is made to the Holders of Convertible Debentures or to
the Trustee.

         In the event that, notwithstanding the foregoing, any payment or
distribution of assets of the Company of any kind or character, whether in cash,
property or securities, prohibited by the foregoing, shall be received by the
Trustee or the Holders of the Convertible Debentures before all Senior
Indebtedness is paid in full, or provision is made for such payment in money in
accordance with its terms, such payment or distribution shall be held in trust
for the benefit of and shall be paid over or delivered to the holders of Senior
Indebtedness or their representative or representatives, or to the trustee or
trustees under any indenture pursuant to which any instruments evidencing such
Senior Indebtedness may have been issued, and their respective interests may
appear, as calculated by the Company, for application to the payment of all
Senior Indebtedness remaining unpaid to the extent necessary to pay such Senior
Indebtedness in full in money in accordance with its terms, after giving effect
to any concurrent payment or distribution to or for the holders of such Senior
Indebtedness.

         For purposes of this Article Twelve, the words, "cash, property or
securities" shall not be deemed to include shares of stock of the Company as
reorganized or readjusted, or securities of the Company or any other corporation
provided for by a plan of reorganization or readjustment, the payment of which
is subordinated at least to the extent provided in this Article Twelve with
respect to the Convertible Debentures to the payment of all Senior Indebtedness
which may at the time be outstanding; provided, that (i) such Senior
Indebtedness is assumed by the new corporation, if any, resulting from any such
reorganization or readjustment, and (ii) the rights of the holders of such
Senior Indebtedness are not, without the consent of such holders, altered by
such reorganization or readjustment.

The consolidation of the Company with, or the merger of the Company with or
into, another Person or the liquidation or dissolution of the Company following
the conveyance, transfer or lease of all or substantially all its properties and
assets on a consolidated basis to another Person upon the terms and conditions
provided for in Article Eight hereof shall not be deemed a dissolution, winding
up, liquidation or reorganization for the purposes of this Section 1203 if such
other Person shall, as a part of such consolidation, merger, conveyance,
transfer or lease, comply with the conditions stated in Article Eight hereof.
Nothing in Section 1202 or in this Section 1203 shall apply to claims of, or
payments to, the Trustee under or pursuant to Section 607 hereof.

SECTION 2404. Subrogation.

         Subject to the payment in full of all Senior Indebtedness, the rights
of the Holders of the Convertible Debentures shall be subrogated to the rights
of the holders of such Senior Indebtedness to receive payments or distributions
of cash, property or securities of the Company, as the case may be, applicable
to such Senior Indebtedness until the principal of (and premium, if any,) and
interest (including Additional Payments, if any) on the Convertible Debentures
shall be paid in full; and, for the purposes of such subrogation, no payments or
distributions to the holders of such Senior Indebtedness of any cash, property
or securities to which the Holders of the Convertible Debentures or the Trustee
would be entitled except for the provisions of this Article Twelve, and no
payment over pursuant to the provisions of this Article Twelve, to or for the
benefit of the holders of such Senior Indebtedness by Holders of the Convertible
Debentures or the Trustee, shall, as between the Company, its creditors other
than holders of Senior Indebtedness, and the Holders of the Convertible
Debentures, be deemed to be a payment by the Company to or on account of such
Senior Indebtedness. It is understood that the provisions of this Article Twelve
are and are intended solely for the purposes of defining the relative rights of
the Holders of the Convertible Debentures, on the one hand, and the holders of
such Senior Indebtedness on the other hand.

         Nothing contained in this Article Twelve or elsewhere in this Indenture
or in the Convertible Debentures is intended to or shall impair, as between the
Company, its creditors other than the holders of Senior Indebtedness, and the
Holders of the Convertible Debentures, the obligation of the Company, which is
absolute and unconditional, to pay to the Holders of the Convertible Debentures
the principal of (and premium, if any) and interest (including Additional
Payments, if any) on the Convertible Debentures as and when the same shall
become due and payable in accordance with their terms, or is intended to or
shall affect the relative rights of the Holders of the Convertible Debentures
and creditors of the Company, as the case may be, other than the holders of
Senior Indebtedness, nor shall anything herein or therein prevent the Trustee or
the Holder of any Convertible Debenture from exercising all remedies otherwise
permitted by applicable law upon default under this Indenture, subject to the
rights, if any, under this Article Twelve of the holders of such Senior
Indebtedness in respect of cash, property or Convertible Debentures of the
Company, as the case may be, received upon the exercise of any such remedy.



                                     - 65 -
<PAGE>   74


         Upon any payment or distribution of assets of the Company referred to
in this Article Twelve, the Trustee, subject to the provisions of Section 603,
and the Holders of the Convertible Debentures, shall be entitled to rely upon
any order or decree made by any court of competent jurisdiction in which such
dissolution, winding up, liquidation or reorganization proceedings are pending,
or a certificate of the receiver, trustee in bankruptcy, liquidation trustee,
agent or other Person making such payment or distribution, delivered to the
Trustee or to the Holders of the Convertible Debentures, for the purposes of
ascertaining the Persons entitled to participate in such distribution, the
holders of the Senior Indebtedness and other indebtedness of the Company, as the
case may be, the amount thereof or payable thereon, the amount or amounts paid
or distributed thereon and all other facts pertinent thereto or to this Article
Twelve.

SECTION 2405. Trustee to Effectuate Subordination.

         Each Holder of Convertible Debentures by such Holder's acceptance
thereof authorizes and directs the Trustee on such Holder's behalf to take such
action as may be necessary or appropriate to effectuate the subordination
provided in this Article Twelve and appoints the Trustee as such Holder's
attorney-in-fact for any and all such purposes.

SECTION 2406. Notice by the Company.

         The Company shall give prompt written notice to a Responsible Officer
of the Trustee of any fact known to the Company which would prohibit the making
of any payment of monies to or by the Trustee in respect of the Convertible
Debentures pursuant to the provisions of this Article Twelve. Notwithstanding
the provisions of this Article Twelve or any other provision of this Indenture,
the Trustee shall not be charged with knowledge of the existence of any facts
which would prohibit the making of any payment of monies to or by the Trustee in
respect of the Convertible Debentures pursuant to the provision of this Article
Twelve, unless and until a Responsible Officer of the Trustee shall have
received written notice thereof at the Corporate Trust Office of the Trustee
from the Company or a holder or holders of Senior Indebtedness or from any
trustee therefor; and before the receipt of any such written notice, the
Trustee, subject to the provisions of Section 603 hereof, shall be entitled in
all respects to assume that no such facts exist; provided, however, that if the
Trustee shall not have received the notice provided for in this Section 1206 at
least two Business Days prior to the date upon which by the terms hereof any
money may become payable for any purpose (including, without limitation, the
payment of the principal of (and premium, if any) or interest (including
Additional Payments, if any) on any Convertible Debenture), then, anything
herein contained to the contrary notwithstanding, the Trustee shall have full
power and authority to receive such money and to apply the same to the purposes
for which they were received, and shall not be affected by any notice to the
contrary which may be received by it within two Business Days prior to such
date.

         The Trustee, subject to the provisions of Section 603, shall be
entitled to rely on the delivery to it of a written notice by a Person
representing himself to be a holder of



                                     - 66 -
<PAGE>   75

Senior Indebtedness (or a trustee on behalf of such holder) to establish that
such notice has been given by a holder of such Senior Indebtedness or a trustee
on behalf of any such holder or holders. In the event that the Trustee
determines in good faith that further evidence is required with respect to the
right of any Person as a holder of Senior Indebtedness to participate in any
payment or distribution pursuant to this Article Twelve, the Trustee may request
such Person to furnish evidence to the reasonable satisfaction of the Trustee as
to the amount of Senior Indebtedness held by such Person, the extent to which
such Person is entitled to participate in such payment or distribution and any
other facts pertinent to the right of such Person under this Article Twelve,
and, if such evidence is not furnished, the Trustee may defer any payment to
such Person pending judicial determination as to the right of such Person to
receive such payment.

SECTION 2407. Rights of the Trustee; Holders of Senior Indebtedness.

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

         With respect to the holders of Senior Indebtedness of the Company, the
Trustee undertakes to perform or to observe only such of its covenants and
obligations as are set forth in this Article Twelve, and no implied covenants or
obligations with respect to the holders of such Senior Indebtedness shall be
read into this Indenture against the Trustee. The Trustee shall not be deemed to
owe any fiduciary duty to the holders of such Senior Indebtedness and, subject
to the provisions of Section 603, the Trustee shall not be liable to any holder
of such Senior Indebtedness if it shall pay over or deliver to Holders of
Convertible Debentures, the Company or any other Person money or assets to which
any holder of such Senior Indebtedness shall be entitled by virtue of this
Article Twelve or otherwise. With respect to the holders of Senior Indebtedness,
the Trustee undertakes to perform or to observe only such of its covenants or
obligations as are specifically set forth in this Article Twelve and no implied
covenants or obligations with respect to holders of Senior Indebtedness shall be
read into this Indenture against the Trustee.

SECTION 2408. Subordination May Not Be Impaired.

         No right of any present or future holder of any Senior Indebtedness to
enforce subordination as herein provided shall at any time in any way be
prejudiced or impaired by any act or failure to act on the part of the Company
or by any act or failure to act, in good faith, by any such holder, or by any
noncompliance by the Company with the terms, provisions and covenants of this
Indenture, regardless of any knowledge thereof which any such holder may have or
otherwise be charged with.

         Without in any way limiting the generality of the foregoing paragraph,
the holders of Senior Indebtedness may, at any time and from time to time,
without the consent 



                                     - 67 -
<PAGE>   76

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

                                  ARTICLE XXVI

                      Conversion of Convertible Debentures

SECTION 2601. Conversion Rights.

         Subject to and upon compliance with the provisions of this Article, the
Convertible Debentures are convertible, at the option of the Holder, at any time
on or before 5:00 p.m. (New York City time) on the Business Day immediately
preceding the date of repayment of such Convertible Debentures, whether at
maturity or upon redemption (either at the option of the Company or pursuant to
a Tax Event), into fully paid and nonassessable shares of Company Common Stock
of the Company at an initial conversion rate of 0.4545 shares of Company Common
Stock for each $25 in aggregate principal amount of Convertible Debentures
(equal to a conversion price of $55.00 per share of Company Common Stock),
subject to adjustment as described in this Article Thirteen. A Holder of
Convertible Debentures may convert any portion of the principal amount of the
Convertible Debentures into that number of fully paid and nonassessable shares
of Company Common Stock (calculated as to each conversion to the nearest 1/100th
of a share) obtained by dividing the principal amount of the Convertible
Debentures to be converted by such conversion price. In case a Convertible
Debenture or portion thereof is called for redemption, such conversion right in
respect of the Convertible Debenture or portion so called shall expire at 5:00
p.m. (New York City time) on the Business Day immediately preceding the
corresponding Redemption Date, unless the Company defaults in making the payment
due upon redemption.

SECTION 2602. Conversion Procedures.

         (a) In order to convert all or a portion of the Convertible Debentures,
the Holder thereof shall deliver to the Conversion Agent an irrevocable Notice
of Conversion setting forth the principal amount of Convertible Debentures to be
converted, together with the name or names, if other than the Holder, in which
the shares of Company Common Stock should be issued upon conversion and, if such
Convertible Debentures are definitive Convertible Debentures, surrender to the
Conversion Agent the Convertible Debentures to be converted, duly endorsed or
assigned to the Company or in blank. In addition, a holder of Preferred
Securities may exercise its right under the Trust Agreement to convert such
Preferred Securities into Company Common Stock by delivering to the Conversion
Agent an irrevocable Notice of Conversion setting forth the information called
for by the preceding sentence and directing the Conversion Agent (i) to exchange
such Preferred Security for a portion of the Convertible Debentures held by the
Trust (at an exchange rate of $25 liquidation amount of Convertible Debentures
for each Preferred Security) and (ii) to immediately convert such Convertible
Debentures, on behalf of such holder, into Company Common Stock of the Company
pursuant to this Article Thirteen and, if such Preferred Securities are in
definitive form, surrendering such Preferred Securities, duly endorsed or
assigned to the Company or in blank. So long as any Preferred Securities are
outstanding, 



                                     - 69 -
<PAGE>   78

the Trust shall not convert any Convertible Debentures except pursuant to a
Notice of Conversion delivered to the Conversion Agent by a holder of Preferred
Securities.

         If a Notice of Conversion is delivered on or after the Regular Record
Date and prior to the subsequent Interest Payment Date, the Holder will be
entitled to receive the interest payable on the subsequent Interest Payment Date
on the portion of Convertible Debentures to be converted notwithstanding the
conversion thereof prior to such Interest Payment Date. Except as otherwise
provided in the immediately preceding sentence, in the case of any Convertible
Debenture which is converted, interest whose Stated Maturity is after the date
of conversion of such Convertible Debenture shall not be payable, and the
Company shall not make nor be required to make any other payment, adjustment or
allowance with respect to accrued but unpaid interest (including Additional
Payments, if any) on the Convertible Debentures being converted, which shall be
deemed to be paid in full. If any Convertible Debenture called for redemption is
converted, any money deposited with the Trustee or with any Paying Agent or so
segregated and held in trust for the redemption of such Convertible Debenture
shall (subject to any right of the Holder of such Convertible Debenture or any
Predecessor Security to receive interest as provided in the last paragraph of
Section 307 and this paragraph) be paid to the Company upon Company Request or,
if then held by the Company, shall be discharged from such trust.

         Each conversion shall be deemed to have been effected immediately prior
to 5:00 p.m. (New York City time) on the day on which the Notice of Conversion
was received (the "Conversion Date") by the Conversion Agent from the Holder or
from a holder of the Preferred Securities effecting a conversion thereof
pursuant to its conversion rights under the Trust Agreement, as the case may be.
The Person or Persons entitled to receive the Company Common Stock issuable upon
such conversion shall be treated for all purposes as the record holder or
holders of such Company Common Stock as of the Conversion Date. As promptly as
practicable on or after the Conversion Date, the Company shall issue and deliver
at the office of the Conversion Agent, unless otherwise directed by the Holder
in the Notice of Conversion, a certificate or certificates for the number of
full shares of Company Common Stock issuable upon such conversion, together with
the cash payment, if any, in lieu of any fraction of any share to the Person or
Persons entitled to receive the same. The Conversion Agent shall deliver such
certificate or certificates to such Person or Persons.

         (b) Subject to any right of the Holder of such Convertible Debenture or
any Predecessor Security to receive interest as provided in the last paragraph
of Section 307 and the second paragraph of Clause (a) of Section 1302, the
Company's delivery upon conversion of the fixed number of shares of Company
Common Stock into which the Convertible Debentures are convertible (together
with the cash payment, if any, in lieu of fractional shares) shall be deemed to
satisfy the Company's obligation to pay the principal amount at Maturity of the
portion of Convertible Debentures so converted and any unpaid interest
(including Additional Payments, if any) accrued on such Convertible Debentures
at the time of such conversion.

         (c) No fractional shares of Company Common Stock will be issued as a
result of conversion, but in lieu thereof, the Company shall pay to the
Conversion Agent a cash adjustment in an amount equal to the same fraction of
the last reported sale price of such fractional interest on the date on which
the Convertible Debentures or Preferred Securities, as the case may be, were
duly surrendered to the Conversion Agent for conversion, or, if such day is not
a Trading Day, on the next Trading Day, and the Conversion Agent in turn will
make such payment, if any, to the Holder of the Convertible Debentures or the
holder of the Preferred Securities so converted.

         (d) In the event of the conversion of any Convertible Debenture in part
only, a new Convertible Debenture or Convertible Debentures for the unconverted
portion thereof will be issued in the name of the Holder thereof upon the
cancellation thereof in accordance with Section 305.

         (e) In effecting the conversion transactions described in this Section,
the Conversion Agent is acting as agent of the holders of Preferred Securities
(in the exchange of Preferred Securities for Convertible Debentures) and as
agent of the Holders of Convertible Debentures (in the conversion of Convertible
Debentures into Company Common Stock), as the case may be, directing it to
effect such conversion transactions. The Conversion Agent is hereby authorized
(i) to exchange Convertible Debentures held by the Trust from time to time for
Preferred Securities in connection with the conversion of such Preferred
Securities in accordance with this Article Thirteen and (ii) to convert all or a
portion of the Convertible Debentures into Company Common Stock and thereupon to
deliver such shares of Company Common Stock in accordance with the provisions of
this Article Thirteen and to deliver to the Trust a new Convertible Debenture or
Convertible Debentures for any resulting unconverted principal amount.

         (f) Except as provided in Section 202, all shares of Company Common
Stock delivered upon any conversion of Restricted Securities shall bear a
Restrictive Securities Legend substantially in the form of the legend required
to be set forth on such Convertible Debentures and shall be subject to the
restrictions on transfer provided in such legend and in Section 314 hereof.
Neither the Trustee nor the Conversion Agent shall have any responsibility for
the inclusion or content of any such Restrictive Securities Legend on such
Company Common Stock; provided, however, that the Trustee or the Conversion
Agent shall have provided to the Company or to the Company's transfer agent for
such Company Common Stock, prior to or concurrently with a request to the
Company to deliver to such Conversion Agent certificates for such Company Common
Stock, written notice that the Convertible Debentures delivered for conversion
are Restricted Securities.

SECTION 2603. Conversion Price Adjustments.

         The conversion price shall be subject to adjustment (without
duplication) from time to time as follows:



                                     - 71 -
<PAGE>   80

         (a) In case the Company shall, while any of the Convertible Debentures
are outstanding, (i) pay a dividend or make a distribution with respect to its
Company Common Stock in shares of Company Common Stock, (ii) subdivide its
outstanding shares of Company Common Stock, (iii) combine its outstanding shares
of Company Common Stock into a smaller number of shares or (iv) issue by
reclassification of its shares of Company Common Stock any shares of capital
stock of the Company, the conversion price in effect immediately prior to such
action shall be adjusted so that the Holder of any Convertible Debentures
thereafter surrendered for conversion shall be entitled to receive the number of
shares of capital stock of the Company which he would have owned immediately
following such action had such Convertible Debentures been converted immediately
prior thereto. An adjustment made pursuant to this Section 1303(a) shall become
effective immediately after the record date in the case of a dividend or other
distribution and shall become effective immediately after the effective date in
case of a subdivision, combination or reclassification (or immediately after the
record date if a record date shall have been established for such event). If, as
a result of an adjustment made pursuant to this Section 1303(a), the Holder of
any Convertible Debenture thereafter surrendered for conversion shall become
entitled to receive shares of two or more classes or series of capital stock of
the Company, the Board of Directors (whose determination shall be conclusive and
shall be described in a Board Resolution filed with the Trustee) shall determine
the allocation of the adjusted conversion price between or among shares of such
classes or series of capital stock.

         (b) In case the Company shall, while any of the Convertible Debentures
are outstanding, issue rights or warrants to all holders of its Company Common
Stock entitling them (for a period expiring within 45 days after the record date
mentioned in this Section 1303(b)) to subscribe for or purchase shares of
Company Common Stock at a price per share less than the current market price per
share of Company Common Stock (as determined pursuant to 1303(f) below) on such
record date, the conversion price for the Convertible Debentures shall be
adjusted so that the same shall equal the price determined by multiplying the
conversion price in effect immediately prior to the date of issuance of such
rights or warrants by a fraction of which the numerator shall be the number of
shares of Company Common Stock outstanding on the date of issuance of such
rights or warrants plus the number of shares which the aggregate offering price
of the total number of shares so offered for subscription or purchase would
purchase at such current market price, and of which the denominator shall be the
number of shares of Company Common Stock outstanding on the date of issuance of
such rights or warrants plus the number of additional shares of Company Common
Stock offered for subscription or purchase. Such adjustment shall become
effective immediately after the record date for the determination of
stockholders entitled to receive such rights or warrants. For the purposes of
this subsection, the number of shares of Company Common Stock at any time
outstanding shall not include shares held in the treasury of the Company. The
Company shall not issue any rights or warrants in respect of shares of Company
Common Stock held in the treasury of the Company. In case any rights or warrants
referred to in this subsection in respect of which an adjustment shall have been
made shall expire unexercised within 45 days after the same shall have been
distributed or issued by the Company, the conversion price shall be readjusted
at the time of such 



                                     - 72 -
<PAGE>   81

expiration to the conversion price that would have been in effect if no
adjustment had been made on account of the distribution or issuance of such
expired rights or warrants.

         (c) Subject to the last sentence of this Section 1303(c), in case the
Company shall, by dividend or otherwise, distribute to all holders of its
Company Common Stock evidences of its indebtedness, shares of any class or
series of capital stock, cash or assets (including securities, but excluding any
rights or warrants referred to in Section 1303(b), any dividend or distribution
paid exclusively in cash and any dividend or distribution referred to in Section
1303(a)), the conversion price shall be reduced so that the same shall equal the
price determined by multiplying the conversion price in effect immediately prior
to the effectiveness of the conversion price reduction contemplated by this
Section 1303(c) by a fraction of which the numerator shall be the current market
price per share (determined as provided in Section 1303(f)) of the Company
Common Stock on the date fixed for the payment of such distribution (the
"Reference Date") less the fair market value (as determined in good faith by the
Board of Directors, whose determination shall be conclusive and described in a
resolution of the Board of Directors), on the Reference Date, of the portion of
the evidences of indebtedness, shares of capital stock, cash and assets so
distributed applicable to one share of Company Common Stock and the denominator
shall be such current market price per share of the Company Common Stock, such
reduction to become effective immediately prior to the opening of business on
the day following the Reference Date. In the event that such dividend or
distribution is not so paid or made, the conversion price shall again be
adjusted to be the conversion price which would then be in effect if such
dividend or distribution had not occurred. If the Board of Directors determines
the fair market value of any distribution for purposes of this Section 1303(c)
by reference to the actual or when issued trading market for any securities
comprising such distribution, it must in doing so consider the prices in such
market over the same period used in computing the current market price per share
of Company Common Stock (determined as provided in Section 1303(f)). For
purposes of this Section 1303(c), any dividend or distribution that includes
shares of Company Common Stock or rights or warrants to subscribe for or
purchase shares of Company Common Stock shall be deemed instead to be (1) a
dividend or distribution of the evidences of indebtedness, shares of capital
stock, cash or assets other than such shares of Company Common Stock or such
rights or warrants (making any conversion price reduction required by this
Section 1303(c)) immediately followed by (2) a dividend or distribution of such
shares of Company Common Stock or such rights or warrants (making any further
conversion price reduction required by Section 1303(a) or 1303(b)), except (A)
the Reference Date of such dividend or distribution as defined in this 1303(c)
shall be substituted as (a) "the record date in the case of a dividend or other
distribution," and (b) "the record date for the determination of stockholders
entitled to receive such rights or warrants" and (c) "the date fixed for such
determination" within the meaning of Sections 1303(a) and 1303(b) and (B) any
shares of Company Common Stock included in such dividend or distribution shall
not be deemed outstanding for purposes of computing any adjustment of the
conversion price in Section 1303(a).



                                     - 73 -
<PAGE>   82

         (d) In case the Company shall pay or make a dividend or other
distribution on its Company Common Stock exclusively in cash (excluding all
regular cash dividends, if the annualized amount thereof per share of Company
Common Stock does not exceed 20% of the current market price per share
determined as provided in Section 1303(f) of the Company Common Stock on the
Trading Day immediately preceding the date of declaration of such dividend), the
conversion price shall be reduced so that the same shall equal the price
determined by multiplying the conversion price in effect immediately prior to
the effectiveness of the conversion price reduction contemplated by this Section
1303(d) by a fraction of which the numerator shall be the current market price
per share (determined as provided in Section 1303(f)) of the Company Common
Stock on the date fixed for the payment of such distribution less the amount of
cash so distributed and not excluded as provided applicable to one share of
Company Common Stock and the denominator shall be such current market price per
share of the Company Common Stock, such reduction to become effective
immediately prior to the opening of business on the day following the date fixed
for the payment of such distribution; provided, however, that in the event the
portion of the cash so distributed applicable to one share of Company Common
Stock is equal to or greater than the current market price per share (as defined
in Section 1303(f)) of the Company Common Stock on the record date mentioned
above, in lieu of the foregoing adjustment, adequate provision shall be made so
that each Holder of shares of Convertible Debentures shall have the right to
receive upon conversion the amount of cash such Holder would have received had
such Holder converted each share of the Convertible Debentures immediately prior
to the record date for the distribution of the cash. In the event that such
dividend or distribution is not so paid or made, the conversion price shall
again be adjusted to be the conversion price which would then be in effect if
such record date had not been fixed.

         (e) In case a tender or exchange offer (other than an odd-lot offer)
made by the Company or any Subsidiary of the Company for all or any portion of
the Company's Company Common Stock shall expire and such tender or exchange
offer shall involve the payment by the Company or such Subsidiary of
consideration per share of Company Common Stock having a fair market value (as
determined in good faith by the Board of Directors, whose determination shall be
conclusive and described in a resolution of the Board of Directors) at the last
time (the "Expiration Time") tenders or exchanges may be made pursuant to such
tender or exchange offer (as it shall have been amended) that exceeds 110% of
the current market price per share (determined as provided in Section 1303(f))
of the Company Common Stock on the Trading Day next succeeding the Expiration
Time, the conversion price shall be reduced so that the same shall equal the
price determined by multiplying the conversion price in effect immediately prior
to the effectiveness of the conversion price reduction contemplated by this
Section 1303(e) by a fraction of which the numerator shall be the number of
shares of Company Common Stock outstanding (including any tendered or exchanged
shares) at the Expiration Time multiplied by the current market price per share
(determined as provided in Section 1303(f)) of the Company Common Stock on the
Trading Day next succeeding the Expiration Time and the denominator shall be the
sum of (x) the fair market value (determined as aforesaid) of the aggregate
consideration payable to stockholders based on the acceptance (up to any maximum
specified in the terms



                                     - 74 -
<PAGE>   83

of the tender or exchange offer) of all shares validly tendered or exchanged and
not withdrawn as of the Expiration Time (the shares deemed so accepted, up to
any such maximum, being referred to as the "Purchased Shares") and (y) the
product of the number of shares of Company Common Stock outstanding (less any
Purchased Shares) at the Expiration Time and the current market price per share
(determined as provided in Section 1303(f)) of the Company Common Stock on the
Trading Day next succeeding the Expiration Time, such reduction to become
effective immediately prior to the opening of business on the day following the
Expiration Time.

         (f) For the purpose of any computation under Section 1303(b), 1303(c),
1303(d) or 1303(e), the current market price per share of Company Common Stock
on any date in question shall be deemed to be the average of the daily Closing
Prices for the five consecutive Trading Days selected by the Company commencing
not more than 20 Trading Days before, and ending not later than, the earlier of
the day in question or, if applicable, the day before the "ex" date with respect
to the issuance or distribution requiring such computation; provided, however,
that if another event occurs that would require an adjustment pursuant to
Section 1303(a) through (e), inclusive, the Board of Directors may make such
adjustments to the Closing Prices during such five Trading Day period as it
deems appropriate to effectuate the intent of the adjustments in this Section
1303, in which case any such determination by the Board of Directors shall be
set forth in a Board Resolution and shall be conclusive. For purposes of this
paragraph, the term "ex" date, (i) when used with respect to any issuance or
distribution, means the first date on which the Company Common Stock trades
regular way on the New York Stock Exchange or on such successor securities
exchange as the Company Common Stock may be listed or in the relevant market
from which the Closing Prices were obtained without the right to receive such
issuance or distribution, and (ii) when used with respect to any tender or
exchange offer, means the first date on which the Company Common Stock trades
regular way on such securities exchange or in such market after the Expiration
Time of such offer.

         (g) The Company may make such reductions in the conversion price, in
addition to those required by Sections 1303 (a) through (e), as it considers to
be advisable to avoid or diminish any income tax to holders of Company Common
Stock or rights to purchase Company Common Stock resulting from any dividend or
distribution of stock (or rights to acquire stock) or from any event treated as
such for income tax purposes. The Company from time to time may reduce the
conversion price by any amount for any period of time if the period is at least
20 days, the reduction is irrevocable during the period, and the Board of
Directors of the Company shall have made a determination that such reduction
would be in the best interest of the Company, which determination shall be
conclusive. Whenever the conversion price is reduced pursuant to the preceding
sentence, the Company shall mail to holders of record of the Convertible
Debentures a notice of the reduction at least 15 days prior to the date the
reduced conversion price takes effect, and such notice shall state the reduced
conversion price and the period it will be in effect.



                                     - 75 -
<PAGE>   84

         (h) No adjustment in the conversion price shall be required unless such
adjustment would require an increase or decrease of at least 1% in the
conversion price; provided, however, that any adjustments which by reason of
this Section 1303(h) are not required to be made shall be carried forward and
taken into account in determining whether any subsequent adjustment shall be
required.

         (i) If any action would require adjustment of the conversion price
pursuant to more than one of the provisions described above, only one adjustment
shall be made and such adjustment shall be the amount of adjustment that has the
highest absolute value to the Holder of the Convertible Debentures.

SECTION 2604. Fundamental Change.

         (a) In the event that the Company is party to any transaction
(including, without limitation, a merger other than a merger that does not
result in a reclassification, conversion, exchange or cancellation of Company
Common Stock), consolidation, sale of all or substantially all of the assets of
the Company, recapitalization or reclassification of Company Common Stock (other
than a change in par value, or from par value to no par value, or from no par
value to par value or as a result of a subdivision or combination of Company
Common Stock) or any compulsory share exchange (each of the foregoing being
referred to as a "Transaction"), in each case, as a result of which shares of
Company Common Stock shall be converted into the right to receive, or shall be
exchanged for, (i) in the case of any Transaction other than a Transaction
involving a Common Stock Fundamental Change (and subject to funds being legally
available for such purpose under applicable law at the time of such conversion),
securities, cash or other property, each Preferred Security shall thereafter be
convertible into the kind and, in the case of a Transaction which does not
involve a Fundamental Change, amount of securities, cash and other property
receivable upon the consummation of such Transaction by a holder of that number
of shares of Company Common Stock into which a Preferred Security was
convertible immediately prior to such Transaction, or (ii) in the case of a
Transaction involving a Common Stock Fundamental Change, common stock, each
Preferred Security shall thereafter be convertible (in the manner described
therein) into common stock of the kind received by holders of Company Common
Stock (but in each case after giving effect to any adjustment discussed below
relating to a Fundamental Change if such Transaction constitutes a Fundamental
Change). The holders of Preferred Securities will have no voting rights with
respect to any Transaction.

         (b) If any Fundamental Change occurs, then the conversion price in
effect will be adjusted immediately after such Fundamental Change as described
below. In addition, in the event of a Common Stock Fundamental Change, each
Preferred Security shall be convertible solely into common stock of the kind
received by holders of Company Common Stock as a result of such Common Stock
Fundamental Change.



                                     - 76 -
<PAGE>   85

         (c) The conversion price in the case of any Transaction involving a
Fundamental Change will be adjusted immediately after such Fundamental Change:

                  (i)  in the case of a Non-Stock Fundamental Change, the
         conversion price of the Preferred Securities will thereupon become the
         lower of (A) the conversion price in effect immediately prior to such
         Non-Stock Fundamental Change, but after giving effect to any other
         prior adjustments effected pursuant to the preceding paragraphs, and
         (B) the greater of the Applicable Price or the then applicable
         Reference Market Price plus any then-accrued and unpaid distributions
         on one Preferred Security; and

                  (ii) in the case of a Common Stock Fundamental Change, the
         conversion price of the Preferred Securities in effect immediately
         prior to such Common Stock Fundamental Change, but after giving effect
         to any other prior adjustments effected pursuant to the preceding
         paragraphs, will thereupon be adjusted by multiplying such conversion
         price by a fraction of which the numerator will be the Purchaser Stock
         Price and the denominator will be the Applicable Price; provided,
         however, that in the event of a Common Stock Fundamental Change in
         which (A) 100% of the value of the consideration received by a holder
         of Company Common Stock is common stock of the successor, acquirer, or
         other third party (and cash, if any, is paid only with respect to any
         fractional interests in such common stock resulting from such Common
         Stock Fundamental Change) and (B) all Company Common Stock will be have
         been exchanged for, converted into, or acquired for common stock (and
         cash with respect to fractional interests) of the successor, acquirer,
         or other third party, the conversion price of the Preferred Securities
         in effect immediately prior to such Common Stock Fundamental Change
         will thereupon be adjusted by multiplying such conversion price by a
         fraction of which the numerator will be one and the denominator will be
         the number of shares of common stock of the successor, acquirer, or
         other third party received by a holder of one share of Company Common
         Stock as a result of such Common Stock Fundamental Change.

         The Company or the Person formed by such consolidation or resulting
from such merger or which acquired such assets or which acquires the Company's
shares, as the case may be, shall make provision in its certificate or articles
of incorporation or other constituent document to establish such right. Such
certificate or articles of incorporation or other constituent document shall
provide for adjustments which, for events subsequent to the effective date of
such certificate or articles of incorporation or other constituent document,
shall be as nearly equivalent as may be practicable to the adjustments provided
for in this Article Thirteen. The above provisions shall similarly apply to
successive transactions of the foregoing type.

distribution) on its Company Common Stock, other than (A) a dividend payable in
shares of Company Common Stock or (B) a dividend payable in cash that would not
require an adjustment pursuant to Section 1303(c) or 1303(d), or (ii) authorize
a tender or exchange offer that would require an adjustment pursuant to Section
1303(e);

         (b) the Company shall authorize the granting to all holders of Company
Common Stock of rights or warrants to subscribe for or purchase any shares of
stock of any class or series or of any other rights or warrants;

of any reclassification of Company Common Stock (other than a subdivision or
combination of the outstanding Company Common Stock, or a change in par value,
or from par value to no par value, or from no par value to par value), or of any
consolidation or merger to which the Company is a party and for which approval
of any stockholders of the Company shall be required, or of the sale or transfer
of all or substantially all of the assets of the Company or of any compulsory
share exchange whereby the Company Common Stock is converted into other
securities, cash or other property; or

         (c) of the voluntary or involuntary dissolution, liquidation or winding

or effective date hereinafter specified, a notice stating (x) the date on which
a record (if any) is to be taken for the purpose of such dividend, distribution,
rights or warrants or, if a record is not to be taken, the date as of which the
holders of Company Common Stock of record to be entitled to such dividend,
distribution, rights or warrants are to be determined or (y) the date on which
such reclassification, consolidation, merger, sale, transfer, share exchange,
dissolution, liquidation or winding up is expected to become effective, and the
date as of which it is expected that holders of Company Common Stock of record
shall be entitled to exchange their shares of Company Common Stock for
securities, cash or other property deliverable upon such reclassification,
consolidation, merger, sale, transfer, share exchange, dissolution, liquidation
or winding up (but no failure to mail such notice or any defect therein or in
the mailing thereof shall affect the validity of the corporate action required
to be specified in such notice).

SECTION 2607. Certain Defined Terms.

         The following definitions shall apply to terms used in this Article
Thirteen:

         (a) "Closing Price" of any Company Common Stock on any day shall mean
the reported last sale price on such day or in case no sale takes place on such
day, the average of the reported closing bid and asked prices in each case on
the NYSE Consolidated Transactions Tape or, if the stock is not listed or
admitted to trading on the NYSE, on the principal national securities exchange
on which such stock is listed or admitted to trading or, if not listed or

rights to purchase such shares pursuant to any employee benefit plan or program
of the Company or pursuant to any option, warrant, right or exercisable,
exchangeable or convertible security outstanding as of the date the Convertible
Debentures were first issued, shall not be deemed to constitute an issuance of
Company Common Stock or exercisable, exchangeable or convertible securities by
the Company to which any of the adjustment provisions described above applies.
There shall also be no adjustment of the conversion price in case of the
issuance of any stock (or securities convertible into or exchangeable for stock)

                                     - 79 -
<PAGE>   88

SECTION 2609. Certain Additional Rights.

         In case the Company shall, by dividend or otherwise, declare or make a
distribution on its Company Common Stock referred to in Section 1303(c) or
1303(d) (including, without limitation, dividends or distributions referred to
in the last sentence of Section 1303(c)), the Holder of the Convertible
Debentures, upon the conversion thereof subsequent to 5:00 p.m. (New York City
time) on the date fixed for the determination of stockholders entitled to
receive such distribution and prior to the effectiveness of the conversion price
adjustment in respect of such distribution, shall also be entitled to receive
for each share of Company Common Stock into which the Convertible Debentures are
converted, the portion of the shares of Company Common Stock, rights, warrants,
evidences of indebtedness, shares of capital stock, cash and assets so
distributed applicable to one share of Company Common Stock; provided, however,
that, at the election of the Company (whose election shall be evidenced by a
resolution of the Board of Directors) with respect to all Holders so converting,
the Company may, in lieu of distributing to such Holder any portion of such
distribution not consisting of cash or securities of the Company, pay such
Holder an amount in cash equal to the fair market value thereof (as determined
in good faith by the Board of Directors, whose determination shall be conclusive
and described in a resolution of the Board of Directors). If any conversion of
Convertible Debentures described in the immediately preceding sentence occurs
prior to the payment date for a distribution to holders of Company Common Stock
which the Holder of Convertible Debentures so converted is entitled to receive
in accordance with the immediately preceding sentence, the Company may elect
(such election to be evidenced by a resolution of the Board of Directors) to
distribute to such Holder a due bill for the shares of Company Common Stock,
rights, warrants, evidences of indebtedness, shares of capital stock, cash or
assets to which such Holder is so entitled, provided, that such due bill (i)
meets any applicable requirements of the principal national securities exchange
or other market on which the Company Common Stock is then traded and (ii)
requires payment or delivery of such shares of Company Common Stock, rights,
warrants, evidences of indebtedness, shares of capital stock, cash or assets no
later than the date of payment or delivery thereof to holders of shares of
Company Common Stock receiving such distribution.

SECTION 2610. Restrictions on Company Common Stock Issuable Upon Conversion.

         (a) Shares of Company Common Stock to be issued upon conversion of a
Convertible Debenture in respect of Restricted Preferred Securities shall bear
such restrictive legends as the Company may provide in accordance with
applicable law.

         (b) If shares of Company Common Stock to be issued upon conversion of a
Convertible Debenture in respect of Restricted Preferred Securities are to be
registered in a name other than that of the Holder of such Preferred Security,
then the Person in whose name such shares of Company Common Stock are to be
registered must deliver to the Conversion Agent a certificate satisfactory to
the Company and signed by such Person, as to compliance with the restrictions on
transfer applicable to such Preferred Security. Neither the Trustee

nor any Conversion Agent or Registrar shall be required to register in a name
other than that of the Holder shares of Company Common Stock issued upon
conversion of any such Convertible Debenture in respect of such Preferred
Securities not so accompanied by a properly completed certificate.

SECTION 2611. Trustee Not Responsible for Determining Conversion Price or
              Adjustments.

         Neither the Trustee nor any Conversion Agent shall at any time be under
any duty or responsibility to any Holder of any Convertible Debenture to
determine whether any facts exist which may require any adjustment of the
conversion price, or with respect to the nature or extent of any such adjustment
when made, or with respect to the method employed, or herein or in any
supplemental indenture provided to be employed, in making the same. Neither the
Trustee nor any Conversion Agent shall be accountable with respect to the
validity or value (or the kind of account) of any shares of Company Common Stock
or of any securities or property, which may at any time be issued or delivered
upon the conversion of any Convertible Debenture; and neither the Trustee nor
any Conversion Agent makes any representation with respect thereto. Neither the
Trustee nor any Conversion Agent shall be responsible for any failure of the
Company to make any cash payment or to issue, transfer or deliver any shares of
Company Common Stock or stock certificates or other securities or property upon
the surrender of any Convertible Debenture for the purpose of conversion, or,
except as expressly herein provided, to comply with any of the covenants of the
Company contained in Article Ten or this Article Thirteen.

                   [FORM OF REVERSE OF CONVERTIBLE DEBENTURE]

         This Convertible Debenture is one of a duly authorized issue of
securities of the Company designated as its 5 1/4% Convertible Subordinated
Debenture Due 2028 (herein called the "Convertible Debentures"), in aggregate
principal amount of $103,092,775 (or up to $113,402,050 if the over-allotment
option is exercised by the Trust in accordance with the terms and provisions of
the Purchase Agreement), issued and to be issued under an Indenture, dated as of
March 18, 1998 (herein called the "Indenture"), between the Company and Chase
Bank of Texas, National Association, as Trustee (herein called the "Trustee",
which term includes any successor trustee under the Indenture), to which
Indenture and all indentures supplemental thereto reference is hereby made for a
statement of the respective rights, limitations of rights, duties and immunities
thereunder of the Trustee, the Company and the Holders of the Convertible
Debentures, and of the terms upon which the Convertible Debentures are, and are
to be, authenticated and delivered. The terms of the Convertible Debentures
include those stated in the Indenture and those made part of the Indenture by
the Trust Indenture Act of 1939 (15 U.S.C. ss. 77aaa-77bbbb) ("TIA") as in
effect on the date of the Indenture. The Convertible Debentures are subject to,
and qualified by, all such terms, certain of which are summarized hereon, and
holders are referred to the Indenture and the TIA for a statement of such terms.
No reference herein to the Indenture and no provision of this Convertible
Debenture or of the Indenture shall alter or impair the obligation of the
Company, which is absolute and unconditional, to pay the principal of and
interest on this Convertible Debenture at the times, place and rate, and in the
coin or currency, herein prescribed or to convert this Convertible Debenture as
provided in the Indenture. All terms used in this Convertible Debenture which
are defined in the Indenture shall have the meanings assigned to them in the
Indenture. The Company will furnish to any Holder upon written request and
without charge a copy of the Indenture.

         (1) Interest. The Convertible Debentures shall bear interest at the
rate of 5 1/4% per annum, from March 13, 1998 or from the most recent Interest
Payment Date to which interest has been paid or duly provided for, as the case
may be, payable quarterly (subject to deferral as set forth herein), in arrears,
on January 1, April 1, July 1 and October 1 (each an "Interest Payment Date") of
each year, commencing July 1, 1998, until the principal thereof is paid or made
available for payment, and they shall be paid to the Person in whose name the
Convertible Debenture is registered at 5:00 p.m. (New York City time) on the
regular record date for such interest installment, which shall be the March 15,
June 15, September 15 and December 15 next preceding such Interest Payment Date
(the "Regular Record Date"). Interest will compound quarterly and will accrue at
the rate of 5 1/4% per annum on any interest installment in arrears for more
than one quarter or during an extension of an interest payment period as set
forth below.


                                     - 6 -
<PAGE>   100

         The amount of interest payable for any period will be computed on the
basis of a 360-day year of twelve 30-day months. Except as provided in the
following sentence, the amount of interest payable for any period shorter than a
full quarterly period for which interest in computed, will be computed on the
basis of the actual number of days elapsed per 90-day quarter. In the event that
any date on which interest is payable on the Convertible Debentures is not a
Business Day, then payment of interest payable on such date will be made on the
next succeeding day which is a Business Day (and without any interest or other
payment in respect of any such delay), except that, if such Business Day is in
the next succeeding calendar year, such payment shall be made on the immediately
preceding Business Day, in each case with the same force and effect as if made
on such date.

         If at any time while the Property Trustee is the Holder of any
Convertible Debentures, the Trust or the Property Trustee is required to pay any
taxes, duties, assessments or governmental charges of whatever nature (other
than withholding taxes) imposed by the United States, or any other taxing
authority, then, in any such case, the Company shall pay as additional interest
("Additional Interest") on the Convertible Debentures held by the Property
Trustee, such amounts as shall be required so that the net amounts received and
retained by the Trust and the Property Trustee after paying any such taxes,
duties, assessments or other governmental charges will be not less than the
amounts the Trust and the Property Trustee would have received had no such
taxes, duties, assessments or other governmental charges been imposed.

         The principal of and interest on the Convertible Debentures shall be
payable [insert, if global security is issued - to the Depositary Trust Company
or its nominee] [insert, if securities in definitive form are issued - at the
corporate office of the Indenture Trustee in the City of New York or at the
office or agency of the Paying Agent in the United States maintained for such
purpose] in such coin or currency of the United States of America as at the time
of payment is legal tender for payment of public and private debts; provided,
however, that at the option of the Company payment of interest may be made by
(i) check mailed to the address of the Person entitled thereto as such address
shall appear in the Security Register, or (ii) by wire transfer to an account
maintained by the Person entitled thereto as specified in the Securities
Register, provided that proper transfer instructions have been received by the
Regular Record Date.

         (2) Option to Extend Interest Payment Period. The Company shall have
the right at any time during the term of the Convertible Debentures to defer
interest payments (including Additional Payments) from time to time by extending
the interest payment period for successive periods (each, an "Extension Period")
not exceeding 20 consecutive quarters for each such period; provided, no
Extension Period may extend



                                     - 7 -
<PAGE>   101

beyond the maturity date of the Convertible Debentures. At the end of each
Extension Period, the Company shall pay all interest then accrued and unpaid
(including Additional Interest) together with interest thereon compounded
quarterly at the rate specified for the Convertible Debentures to the extent
permitted by applicable law ("Compounded Interest"); provided, that during any
Extension Period, the Company shall (i) not declare or pay dividends on, or make
a distribution with respect to, or redeem or purchase or acquire, or make a
liquidation payment with respect to, any of its capital stock (other than (A)
purchases or acquisitions of shares of Company Common Stock in connection with
the satisfaction by the Company of its obligations under any employee benefit
plans or the satisfaction by the Company of its obligations pursuant to any
contract or security requiring the Company to purchase shares of Company Common
Stock, (B) as a result of a reclassification of the Company's capital stock or
the exchange or conversion of one class or series of the Company's capital stock
for another class or series of the Company's capital stock or (C) the purchase
of fractional interests in shares of the Company's capital stock pursuant to the
conversion or exchange provisions of such capital stock or the security being
converted or exchanged) or make any guarantee payments with respect to the
foregoing, (ii) not make any payment of interest, principal or premium, if any,
on or repay, repurchase or redeem any debt securities (including guarantees)
issued by the Company that rank pari passu with or junior to the Convertible
Debentures (except by conversion into or exchange for shares of its capital
stock) and (iii) not make any guarantee payments with respect to the foregoing
(other than pursuant to the Guarantee). Prior to the termination of any such
Extension Period, the Company may further extend such Extension Period;
provided, that such Extension Period, together with all such previous and
further extensions thereof, may not exceed 20 consecutive quarters or extend
beyond the maturity date of the Convertible Debentures. Upon the termination of
any Extension Period and the payment of all amounts then due, the Company may
commence a new Extension Period, subject to the above requirements. No interest
during an Extension Period shall be due and payable. Notwithstanding anything to
the contrary, the Company shall not have the right at any time to defer any
Additional Interest, including by extending the interest payment period.

         If the Property Trustee is the sole Holder of the Convertible
Debentures at the time the Company selects an Extension Period, the Company
shall give written notice to the Administrative Trustees, the Property Trustee
and the Trustee of its selection of such Extension Period at least one Business
Day prior to the earlier of (i) the date the distributions on the Preferred
Securities are payable or (ii) if the Preferred Securities are listed on the New
York Stock Exchange or other stock exchange or quotation system, the date the
Trust is required to give notice to the New York Stock Exchange or other
applicable self-regulatory organization or to holders of the Preferred
Securities of the record date or the date such distributions are payable, but in
any event not less than 10 Business Days prior to such record date.



                                     - 8 -
<PAGE>   102

         If the Property Trustee is not the sole holder of the Convertible
Debentures at the time the Company selects an Extension Period, the Company
shall give the Holders of the Convertible Debentures and the Trustee written
notice of its selection of such Extension Period at least 10 Business Days prior
to the earlier of (i) the next succeeding Interest Payment Date or (ii) if the
Preferred Securities are listed on the New York Stock Exchange or other stock
exchange or quotation system, the date the Company is required to give notice to
the New York Stock Exchange or other applicable self-regulatory organization or
to holders of the Convertible Debentures on the record or payment date of such
related interest payment, but in any event not less than two Business Days prior
to such record date.

         The quarter in which any notice is given pursuant to paragraphs second
and third of this Section 2 shall be counted as one of the 20 quarters permitted
in the maximum Extension Period permitted under paragraph one of this Section 2.

         (3) Paying Agent and Security Registrar. The Trustee will act as Paying
Agent, Security Registrar and Conversion Agent. The Company may change any
Paying Agent, Security Registrar, co-registrar or Conversion Agent without prior
notice. The Company or any of its Affiliates may act in any such capacity.

         (4) Redemption. The Company shall have the right to redeem the
Convertible Debentures, in whole or in part, at any time or from time to time
after April 3, 2001 upon not less than 30 nor more than 60 days' notice, at the
optional redemption prices (expressed as a percentage of the principal amount of
Convertible Debentures to be redeemed) shown below, plus any accrued and unpaid
interest (including Additional Payments, if any) to the Redemption Date, if
redeemed during the 12-month period beginning April 3:

          2005 and thereafter ...................     100.00%
</TABLE>

         If the Company has deferred interest payments, all unpaid interest must
be paid in cash prior to redemption. Any redemption pursuant to this Section
1101 shall be made pursuant to the provisions of Sections 1103 through 1108
hereof.

<PAGE>   103

         The Convertible Debentures are subject to redemption in whole (but not
in part), at any time within 90 days, if a Tax Event (as defined in the Trust
Agreement) shall occur and be continuing, at a redemption price equal to 100% of
the principal amount thereof plus accrued but unpaid interest (including
Additional Payments, if any) to the Redemption Date. On and after the Redemption
Date, interest ceases to accrue on the Convertible Debentures or portions of
them called for redemption.

         Notice of redemption shall be given by first-class mail, postage
prepaid, mailed not less than 30 nor more than 60 days prior to the Redemption
Date, to each Holder of Convertible Debentures to be redeemed, at such Holder's
address appearing in the Security Register. The Convertible Debentures in
denominations larger than $25 may be redeemed in part but only in integral
multiples of $25. In the event of a redemption of less than all of the
Convertible Debentures, the Convertible Debentures will be chosen for redemption
by the Trustee in accordance with the Indenture.

         If this Convertible Debenture is redeemed subsequent to a Regular
Record Date with respect to any Interest Payment Date specified above and on or
prior to such Interest Payment Date, then any accrued interest will be paid to
the person in whose name this Convertible Debenture is registered at the close
of business on such record date.

         (5) Sinking Fund. The Convertible Debentures are not entitled to the
benefit of any sinking fund.

         (6) Subordination. The payment of the principal of, premium, if any,
and interest (including Additional Payments, if any) on all Convertible
Debentures is subordinated and junior in right of payment to the prior payment
in full of all existing and future Senior Indebtedness, whether outstanding at
the date of this Indenture or thereafter incurred. Each holder, by accepting a
Convertible Debenture, agrees to such subordination and authorizes and directs
the Trustee on its behalf to take such action as may be necessary or appropriate
to effectuate the subordination so provided and appoints the Trustee as its
attorney-in-fact for such purpose.

         "Senior Indebtedness" means in respect of the Company (i) the
principal, premium, if any, and interest in respect of (A) indebtedness of such
obligor for money borrowed and (B) indebtedness evidenced by securities,
debentures, bonds or other similar instruments issued by such obligor, (ii) all
capital lease obligations of such obligor, (iii) all obligations of such obligor
issued or assumed as the deferred purchase price of property, all conditional
sale obligations of such obligor and all obligations of such obligor under any
title retention agreement (but excluding trade accounts payable arising in the
ordinary course of business), (iv) all obligations of such obligor for the
reimbursement of any letter 



                                     - 10 -
<PAGE>   104

of credit, banker's acceptance, security purchase facility or similar credit
transaction, (v) all obligations of the type referred to in clauses (i) through
(iv) above of other Persons for the payment of which such obligor is responsible
or liable as obligor, guarantor or otherwise, and (vi) all obligations of the
type referred to in clauses (i) through (v) above of other Persons secured by
any lien on any property or asset of such obligor (whether or not such
obligation is assumed by such obligor), except for (1) any such indebtedness
that is by its terms subordinated to or pari passu with the Convertible
Debentures and (2) any indebtedness between or among such obligor or its
affiliates, including all other debt securities and guarantees in respect of
those debt securities issued to any other trust, or a trustee of such trust,
partnership, or other entity affiliated with the Company that is, directly or
indirectly, a financing vehicle of the Company (a "Financing Entity") in
connection with the issuance by such Financing Entity of preferred securities or
other securities which rank pari passu with, or junior to, the Preferred
Convertible Debentures. Such Senior Indebtedness shall continue to be Senior
Indebtedness and entitled to the benefits of the subordination provisions
irrespective of any amendment, modification or waiver of any term of such Senior
Indebtedness.

         (7) Conversion. The Holder of any Convertible Debenture has the right,
exercisable at any time on or before 5:00 p.m. (New York City time) on the
Business Day immediately preceding the date of repayment of such Convertible
Debentures, whether at maturity or upon redemption (either at the option of the
Company or pursuant to a Tax Event), to convert the principal amount thereof (or
any portion thereof that is an integral multiple of $25) into fully paid and
nonassessable shares of Company Common Stock of the Company at an initial
conversion rate of 0.4545 shares of Company Common Stock for each $25 in
aggregate principal amount of Convertible Debentures (equal to a conversion
price of $55.00 per share of Company Common Stock), subject to adjustment under
certain circumstances as set forth in Section 1303. The number of shares
issuable upon conversion of a Convertible Debenture is determined by dividing
the principal amount of the Convertible Debenture converted by the conversion
price in effect on the Conversion Date. No fractional shares will be issued upon
conversion but a cash adjustment will be made for any fractional interest. The
outstanding principal amount of any Convertible Debenture shall be reduced by
the portion of the principal amount thereof converted into shares of Company
Common Stock.

         To convert a Convertible Debenture, a Holder must (i) complete and sign
a conversion notice substantially in the form attached hereto, (ii) surrender
the Convertible Debenture to a Conversion Agent, (iii) furnish appropriate
endorsements or transfer documents if required by the Security Registrar or
Conversion Agent and (iv) pay any transfer or similar tax, if required. If a
Notice of Conversion is delivered on or after the Regular Record Date and prior
to the subsequent Interest Payment Date, the Holder will be



                                     - 11 -
<PAGE>   105

entitled to receive the interest payable on the subsequent Interest Payment Date
on the portion of Convertible Debentures to be converted notwithstanding the
conversion thereof prior to such Interest Payment Date. Except as otherwise
provided in the immediately preceding sentence, in the case of any Convertible
Debenture which is converted, interest whose Stated Maturity is after the date
of conversion of such Convertible Debenture shall not be payable, and the
Company shall not make nor be required to make any other payment, adjustment or
allowance with respect to accrued but unpaid interest (including Additional
Payments, if any) on the Convertible Debentures being converted, which shall be
deemed to be paid in full. If any Convertible Debenture called for redemption is
converted, any money deposited with the Trustee or with any Paying Agent or so
segregated and held in trust for the redemption of such Convertible Debenture
shall (subject to any right of the Holder of such Convertible Debenture or any
Predecessor Security to receive interest as provided in the last paragraph of
Section 307 and this paragraph) be paid to the Company upon Company Request or,
if then held by the Company, shall be discharged from such trust.

         (8) Registration Rights. The holders of the Preferred Securities, the
Convertible Debentures issuable in respect of the Preferred Securities, the
shares of Company Common Stock issuable upon conversion of the Preferred
Securities and the Convertible Debentures, and the Guarantee (collectively, the
"Registrable Securities") are entitled to the benefits of a Registration Rights
Agreement, dated as of March 18, 1998, among Central Parking Finance Trust, the
Company and the Initial Purchasers (the "Registration Rights Agreement").
Pursuant to the Registration Rights Agreement, the Company has agreed for the
benefit of the holders of Registrable Securities that (i) it will, at its cost,
use its best efforts within 60 days after the date of original issuance of the
Registrable Securities, to file a shelf registration statement (the "Shelf
Registration Statement") with the Commission with respect to the resales of the
Registrable Securities, (ii) it will use its best efforts to cause such Shelf
Registration Statement to be declared effective by the Commission within 150
days after the date of issuance of the Registrable Securities and (iii) it will
use its best efforts to maintain such Shelf Registration Statement continuously
effective under the Securities Act until two years after the date of original
issuance of the Preferred Securities (or such earlier date as the holders of
Registrable Securities are able to sell all Registrable Securities immediately
without restriction, whether pursuant to Rule 144(k) under the Securities Act or
any successor rule thereto or otherwise) (the "Effectiveness Period"). The Trust
and the Company will be permitted to suspend the use of the prospectus (which is
a part of the Shelf Registration Statement) in connection with sales of
Registrable Securities by holders during certain periods of time under certain
circumstances relating to pending corporate developments relating to the Company
and public filings with the Commission and similar events.



                                     - 12 -
<PAGE>   106

         If (i) on or prior to 60 days following the date of original issuance
         of the Registrable Securities, a Shelf Registration Statement has not
         been filed with the Commission, (ii) on or prior to the 150th day
         following the original issuance of the Registrable Securities, such
         Shelf Registration Statement has not been declared effective, or (iii)
         the Company or the Trust has not filed an amendment as set forth in
         Sections 2(b)(ii) and 3(j) of the Registration Rights Agreement (each
         such event a "Registration Default"), additional interest ("Liquidated
         Damages") will accrue on the Convertible Debentures and, accordingly,
         additional distributions will accrue on the Preferred Securities, from
         and including the day following such Registration Default until such
         time as such Shelf Registration Statement is filed or such Shelf
         Registration Statement is declared effective, as the case may be.
         Liquidated Damages will be paid quarterly in arrears (subject to the
         Company's ability to defer payment of Liquidated Damages during any
         Extension Period), with the first quarterly payment due on the first
         Interest Payment Date following the date on which such Liquidated
         Damages begin to accrue, and will accrue at a rate per annum equal to
         an additional 0.25% of the principal amount or liquidation amount, as
         applicable, to and including the 60th day following such Registration
         Default and 0.50% thereof from and after the 61st day following such
         Registration Default. In the event that during the Effectiveness Period
         the Shelf Registration Statement ceases to be effective for more than
         90 consecutive days or any 120 days, whether or not consecutive, during
         any 12-month period then the interest rate borne by the Debentures and
         the distribution rate borne by the Preferred Securities will each
         increase by an additional 0.50% per annum from such 91st or 121st day,
         as applicable, of the applicable 12-month period such Shelf
         Registration Statement ceases to be effective until the earlier of such
         time as (i) the Shelf Registration Statement again becomes effective or
         (ii) the Effectiveness Period expires.

         (9) Registration, Transfer, Exchange and Denominations. As provided in
the Indenture and subject to certain limitations therein set forth, the transfer
of this Convertible Debenture is registrable in the Security Register, upon
surrender of this Convertible Debenture for registration of transfer at the
office or agency of the Company in New York, New York, duly endorsed by, or
accompanied by a written instrument of transfer in form satisfactory to the
Company and the Security Registrar duly executed by, the Holder hereof or his
attorney duly authorized in writing, and thereupon one or more new Convertible
Debentures, of authorized denominations and for the same aggregate principal
amount, will be issued to the designated transferee or transferees.



                                     - 13 -
<PAGE>   107

         The Convertible Debentures are issuable only in registered form without
coupons in denominations of $25 and integral multiples thereof. No service
charge shall be made for any such registration of transfer or exchange, but the
Company may require payment of a sum sufficient to cover any tax or other
governmental charge payable in connection therewith. Prior to due presentment of
this Convertible Debenture for registration of transfer, the Company, the
Trustee and any agent of the Company or the Trustee may treat the Person in
whose name this Convertible Debenture is registered as the owner hereof for all
purposes, whether or not this Convertible Debenture be overdue, and neither the
Company, the Trustee nor any such agent shall be affected by notice to the
contrary. In the event of redemption or conversion of this Convertible Debenture
in part only, a new Convertible Debenture or Convertible Debentures for the
unredeemed or unconverted portion hereof will be issued in the name of the
Holder hereof upon the cancellation hereof.

         (10) Persons Deemed Owners. Except as provided in the Indenture, the
registered Holder of a Convertible Debenture may be treated as its owner for all
purposes.

         (11) Unclaimed Money. If money for the payment of principal or interest
remains unclaimed for two years, the Trustee and the Paying Agent shall pay the
money back to the Company at its written request. After that, Holders of
Convertible Debentures entitled to the money must look to the Company for
payment unless an abandoned property law designates another Person and all
liability of the Trustee and such Paying Agent with respect to such money shall
cease.

         (12) Defaults and Remedies. The Convertible Debentures shall have the
Events of Default as set forth in Section 501 of the Indenture. Subject to
certain limitations in the Indenture, if an Event of Default occurs and is
continuing, the Trustee by notice to the Company or the Holders of at least 25%
in aggregate principal amount of the then outstanding Convertible Debentures by
notice to the Company and the Trustee may declare all the Convertible Debentures
to be due and payable immediately.

         The Holders of a majority in principal amount of the Convertible
Debentures then outstanding by written notice to the Trustee may rescind an
acceleration and its consequences if the rescission would not conflict with any
judgment or decree and if all existing Events of Default have been cured or
waived except nonpayment of principal or interest that has become due solely
because of the acceleration. Holders may not enforce the Indenture or the
Convertible Debentures except as provided in the Indenture. Subject to certain
limitations, Holders of a majority in principal amount of the then outstanding
Convertible Debentures issued under the Indenture may direct the Trustee in its
exercise of any trust or power. The Convertible Debentures are unsecured general
obligations of the 



                                     - 14 -
<PAGE>   108

Company. The Company must furnish annually compliance certificates to the
Trustee. The above description of Events of Default and remedies is qualified by
reference to, and subject in its entirety by, the more complete description
thereof contained in the Indenture.

         (13) Amendments, Supplements and Waivers. The Indenture permits, with
certain exceptions as therein provided, the amendment thereof and the
modification of the rights and obligations of the Company and the rights of the
Holders of the Convertible Debentures under the Indenture at any time by the
Company and the Trustee with the consent of the Holders of a majority in
aggregate principal amount of the Convertible Debentures at the time
Outstanding. The Indenture also contains provisions permitting the Holders of
specified percentages in aggregate principal amount of the Convertible
Debentures at the time Outstanding, on behalf of the Holders of all the
Convertible Debentures, to waive compliance by the Company with certain
provisions of the Indenture and certain past defaults under the Indenture and
their consequences. Any such consent or waiver by the Holder of this Convertible
Debenture shall be conclusive and binding upon such Holder and upon all future
Holders of this Convertible Debenture and of any Convertible Debenture issued
upon the registration of transfer hereof or in exchange herefor or in lieu
hereof, whether or not notation of such consent or waiver is made upon this
Convertible Debenture.

         (14) Trustee Dealings with the Company. The Trustee, in its individual
or any other capacity may become the owner or pledgee of the Convertible
Debentures and may otherwise deal with the Company or an Affiliate with the same
rights it would have, as if it were not Trustee, subject to certain limitations
provided for in the Indenture and in the TIA. Any Agent may do the same with
like rights.

         (15) No Recourse Against Others. A director, officer, employee or
stockholder, as such, of the Company shall not have any liability for any
obligations of the Company under the Convertible Debentures or the Indenture or
for any claim based on, in respect of or by reason of such obligations or their
creation. Each Holder of the Convertible Debentures by accepting a Convertible
Debenture waives and releases all such liability. The waiver and release are
part of the consideration for the issue of the Convertible Debentures.

         (16) Governing Law. THE INTERNAL LAWS OF THE STATE OF NEW YORK SHALL
GOVERN THE INDENTURE AND THE CONVERTIBLE DEBENTURES WITHOUT REGARD TO CONFLICT
OF LAW PROVISIONS THEREOF.

         (17) Authentication. The Convertible Debentures shall not be valid
until authenticated by the manual signature of an authorized officer of the
Trustee or an authenticating agent.

Agreement that relate to any of the matters set forth in ss. 314(c) of the Trust

SECTION 2.6       Events of Default; Waiver.

                  (a) The Holders of a majority in liquidation amount of
Preferred Securities may, by vote, on behalf of the Holders of all of the
Preferred Securities, waive any past Event of Default in respect of the
Preferred Securities and its consequences, provided that, if the underlying
Event of Default under the Indenture:

                           (i) is not waivable under the Indenture, the Event
         of Default under the Trust Agreement shall also not be waivable; or


                                       14

<PAGE>   21



                          (ii) requires the consent or vote of greater than a
         majority in principal amount of the holders of the Convertible
         Debentures (a "Super Majority") to be waived under the Indenture, the
         Event of Default under the Trust Agreement may only be waived by the
         vote of the Holders of at least the proportion in liquidation amount of
         the Preferred Securities that the relevant Super Majority represents of
         the aggregate principal amount of the Convertible Debentures
         outstanding.

                  The foregoing provisions of this Section 2.6(a) shall be in
lieu of ss. 316(a)(1)(B) of the Trust Indenture Act and such ss. 316(a)(1)(B) of
the Trust Indenture Act is hereby expressly excluded from this Trust Agreement
and the Trust Securities, as permitted by the Trust Indenture Act. Upon such
waiver, any such default shall cease to exist, and any Event of Default with
respect to the Preferred Securities arising therefrom shall be deemed to have
been cured, for every purpose of this Trust Agreement, but no such waiver shall
extend to any subsequent or other default or an Event of Default with respect to
the Preferred Securities or impair any right consequent thereon. Any waiver by
the Holders of the Preferred Securities of an Event of Default with respect to
the Preferred Securities shall also be deemed to constitute a waiver by the
Holders of the Common Securities of any such Event of Default with respect to
the Common Securities for all purposes of this Trust Agreement without any
further act, vote, or consent of the Holders of the Common Securities.

                  (b) The Holders of a majority in liquidation amount of the
Common Securities may, by vote, on behalf of the Holders of all of the Common
Securities, waive any past Event of Default with respect to the Common
Securities and its consequences, provided that, if the underlying Event of
Default under the Indenture:

                          (i)  is not waivable under the Indenture, except where
         the Holders of the Common Securities are deemed to have waived such
         Event of Default under the Trust Agreement as provided below in this
         Section 2.6(b), the Event of Default under the Trust Agreement shall
         also not be waivable; or

                          (ii) requires the consent or vote of a Super Majority
         to be waived, except where the Holders of the Common Securities are
         deemed to have waived such Event of Default under the Trust Agreement
         as provided below in this Section 2.6(b), the Event of Default under
         the Trust Agreement may only be waived by the vote of the Holders of at
         least the proportion in liquidation amount of the Common Securities
         that the relevant Super Majority represents of the aggregate principal
         amount of the Convertible Debentures outstanding;


                                       15

<PAGE>   22


provided further, that each Holder of Common Securities will be deemed to have
waived any such Event of Default and all Events of Default with respect to the
Common Securities and its consequences until all Events of Default with respect
to the Preferred Securities have been cured, waived or otherwise eliminated, and
until such Events of Default have been so cured, waived or otherwise eliminated,
the Property Trustee will be deemed to be acting solely on behalf of the Holders
of the Preferred Securities and only the Holders of the Preferred Securities
will have the right to direct the Property Trustee in accordance with the terms
of the Securities. The foregoing provisions of this Section 2.6(b) shall be in
lieu of ss.ss. 316(a)(1)(A) and 316(a)(1)(B) of the Trust Indenture Act and such
ss.ss. 316(a)(1)(A) and 316(a)(1)(B) of the Trust Indenture Act are hereby
expressly excluded from this Trust Agreement and the Trust Securities, as
permitted by the Trust Indenture Act. Subject to the foregoing provisions of
this Section 2.6(b), upon such waiver, any such default shall cease to exist and
any Event of Default with respect to the Common Securities arising therefrom
shall be deemed to have been cured for every purpose of this Trust Agreement,
but no such waiver shall extend to any subsequent or other default or Event of
Default with respect to the Common Securities or impair any right consequent
thereon.

                  (c) A waiver of an Event of Default under the Indenture by the
Property Trustee at the direction of the Holders of the Preferred Securities,
constitutes a waiver of the corresponding Event of Default under this Trust
Agreement. The foregoing provisions of this Section 2.6(c) shall be in lieu of
ss. 316(a)(1)(B) of the Trust Indenture Act and such ss. 316(a)(1)(B) of the
Trust Indenture Act is hereby expressly excluded from this Trust Agreement and
the Trust Securities, as permitted by the Trust Indenture Act.

SECTION 2.7       Event of Default; Notice.

                  (a) The Property Trustee shall, within 10 days after the
occurrence of an Event of Default, transmit by mail, first class postage
prepaid, to the Holders of the Trust Securities, the Administrative Trustees and
the Depositor, notices of all defaults with respect to the Trust Securities
actually known to a Responsible Officer of the Property Trustee, unless such
defaults have been cured or waived before the giving of such notice (the term
"defaults" for the purposes of this Section 2.7(a) being hereby defined to be an
Event of Default as defined in the Indenture, not including any periods of grace
provided for therein and irrespective of the giving of any notice provided
therein); provided that, except for a default in the payment of principal of (or
premium, if any) or interest on any of the Convertible Debentures or in the
payment of any sinking fund installment established for the Convertible
Debentures, the Property Trustee shall be protected in withholding such notice
if and so long as the board of directors, the executive committee, or a trust
committee of directors and/or Responsible Officers of


                                       16

<PAGE>   23



the Property Trustee in good faith determines that the withholding of such
notice is in the interests of the Holders of the Trust Securities, the
Administrative Trustees and the Depositor.

                  (b) The Property Trustee shall not be deemed to have knowledge
of any default except:

                           (i)  a default under Sections 501(1) and 501(2) of
         the Indenture; or

                           (ii) any default as to which the Property Trustee
         shall have received written notice or of which a Responsible Officer of
         the Property Trustee charged with the administration of the Trust
         Agreement shall have actual knowledge.

               The Trust shall not, and the Issuer Trustees (including the

any amendment, modification or termination of the Indenture or the Convertible
Debentures where such consent shall be required unless the Trust shall have
received an opinion of counsel to the effect that such amendment or
modification will not cause more than an insubstantial risk that (i) the Trust
will be deemed an Investment Company required to be registered under the
Investment Company Act, or (ii) for United States federal income tax purposes
the Trust will not be classified as a grantor trust.

SECTION 3.5         General Authority of the Issuer Trustees.

Trustees to bind the Trust. Persons

Trust.

                    Securities.
              
               The recitals contained in this Trust Agreement and the Trust
Securities shall be taken as the statements of the Depositor, and the Issuer
Trustees do not assume any responsibility for their correctness. The Issuer

          (a)  The Trust may not consolidate, amalgamate, merge with or into, 
or be replaced by, or convey, transfer or lease its properties and assets
substantially as an entirety, to any Person, except as described in Sections
3.9(b) and 3.9(c).

          (b)  The Trust may, with the consent of the majority of the
Administrative Trustees, and without the consent of the Holders of the Trust
Securities, the Delaware Trustee or the Property Trustee, consolidate,
amalgamate, merge with or into, or be replaced by a trust organized as such
under the laws of any state of the United States; provided that:

               (i)  if the Trust is not the survivor, such successor entity
         (the "Successor Entity") either:

                    (A)  expressly assumes all of the obligations of the Trust 
              under the Trust Securities; or



                                      19
<PAGE>   26

                    (B)   substitutes for the Preferred Securities other 
                          securities having substantially the same terms as
                          the Preferred Securities (the "Successor
                          Securities") so long as the Successor Securities
                          rank the same as the Preferred Securities with
                          respect to Distributions, assets and payments upon
                          liquidation, redemption and otherwise;

                          (ii)   the Company expressly acknowledges a trustee 
         of the Successor Entity that possesses the same powers and duties as
         the Property Trustee as the Holder of the Convertible Debentures;

                          (iii)  the Preferred Securities or any Successor
         Securities are listed, or any Successor Securities will be listed upon
         notification of issuance, on any national securities exchange or with
         another organization on which the Preferred Securities are then listed
         or quoted;

                          (iv)   such merger, consolidation, amalgamation or
         replacement does not cause the Preferred Securities (including any
         Successor Securities) to be downgraded by any nationally recognized
         statistical rating organization;

                          (v)    such merger, consolidation, amalgamation or
         replacement does not adversely affect the rights, preferences and
         privileges of the Holders of the Preferred Securities (including any
         Successor Securities) in any material respect (other than with respect
         to any dilution of the Holders' interest in the new entity);

                          (vi)   such Successor Entity has a purpose
         substantially identical to that of the Trust;

                          (vii)  the Depositor guarantees the obligations of
         such Successor Entity under the Successor Securities at least to the
         extent provided by the Preferred Securities Guarantee; and

                          (viii) prior to such merger, consolidation,
         amalgamation or replacement, the Depositor has received an opinion of
         a nationally recognized independent counsel to the Trust reasonably
         acceptable to the Property Trustee and experienced in such matters to
         the effect that:

                                 (A)   such merger, consolidation, amalgamation 
                  or replacement will not adversely affect the rights,
                  preferences and privileges of the Holders of the Trust
                  Securities (including any Successor Securities) in any
                  material respect (other than with respect to any dilution of
                  the Holders' interest in the new entity);



                                       20
<PAGE>   27



                                 (B)   following such merger, consolidation,
                  amalgamation or replacement, neither the Trust nor the
                  Successor Entity will be required to register as an
                  Investment Company; and

                                 (C)   following such merger, consolidation,
                  amalgamation or replacement, the Trust (or the Successor
                  Entity) will be treated as a grantor trust for United States
                  federal income tax purposes.

                  (c) Notwithstanding Section 3.9(b), the Trust shall not,
except with the consent of Holders of 100% in liquidation amount of the Common
Securities, consolidate, amalgamate, merge with or into, or be replaced by any
other entity or permit any other entity to consolidate, amalgamate, merge with
or into, or replace it if such consolidation, amalgamation, merger or
replacement would cause the Trust or Successor Entity to be classified as other
than a grantor trust for United States federal income tax purposes.

SECTION 3.10             Termination of Trust.

                  (a)    The Trust shall terminate:

                         (ii)   upon the filing of a certificate of dissolution

         the Trust Securities, voting together as a single class, to file such
         certificate of cancellation, or the revocation of the Certificate of
         Incorporation of the Depositor and the expiration of 90 days after the
         date of revocation without a reinstatement thereof;

                         (iii)  upon the entry of a decree of judicial 
         dissolution of the Depositor or the Trust;

                         (iv)   upon the redemption, conversion or exchange of 
         all of the Trust Securities and the amounts necessary for redemption,
         conversion or exchange thereof, including any Additional Interest,
         Liquidated Damages, if any, and Compounded Interest, shall have been
         paid to the Holders in accordance with the terms of the Trust
         Securities;

                         (v)    upon the distribution of all of the Convertible
         Debentures upon the occurrence of a Special Event, except in the case
         of a Tax Event that has occurred and is continuing following which the
         Depositor has elected to pay any additional sums such that the net
         amount received by holders of Preferred Securities in



                                       21

         respect of Distributions is not reduced as a result of such Tax Event
         and the Depositor has not revoked any such election or failed to make
         such payments; or

                    (vi)   the expiration of the term of the Trust on April
         1, 2028.

               (b)   As soon as is practicable after the occurrence of an event 
referred to in Section 3.10(a), the Administrative Trustees shall pay (or make
provision for the payment of) all claims against the Trust and shall execute
and file a certificate of cancellation with the Secretary of State of the State
of Delaware.

               (c)   The provisions of Article IX shall survive the termination 
of the Trust.

                  (e) The Property Trustee shall have the legal power to
exercise all of the rights, powers and privileges of a holder of Convertible
Debentures under the Indenture and, if an Event of Default actually known to a
Responsible Officer of the Property Trustee occurs and is continuing, the
Property Trustee shall, to the extent as obligated to do so hereunder, for the
benefit of Holders of the Trust Securities, but subject to the rights of the
Holders pursuant to the terms of such Trust Securities, take such action as it
shall be instructed by the holders of a Majority in Liquidation Amount of the
Trust Securities to enforce its rights as holder of the Convertible Debentures,
including the right to take any Legal Action which arises out of or in
connection with such an Event of Default.

                  (f) Subject to this Section 5.11, the Property Trustee shall
have none of the duties, liabilities, powers or the authority of the
Administrative Trustees set forth in Section 5.9.

                  (g) The Property Trustee must exercise the powers set forth
in this Section 5.11 in a manner that is consistent with the purposes and
functions of the Trust set out in Section 3.3, and the Property Trustee shall

Trust set out in Section 3.3.

SECTION 5.12          Certain Duties and Responsibilities of the Property 
                      Trustee.

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

                  (b) No provision of this Trust Agreement shall be construed
to relieve the Property Trustee from liability for its own grossly negligent
action, its own grossly negligent



                                       33

failure to act, or its own willful misconduct, except that prior to the
occurrence of an Event of Default and after the curing or waiving of all such
Events of Default that may have occurred, in the absence of bad faith on the
part of the Property Trustee, the Property Trustee may conclusively rely, as to
the truth of the statements and the correctness of the opinions expressed
therein, upon any certificates or opinions furnished to the Property Trustee
and conforming to the requirements of this Trust Agreement; but in the case of
any such certificates or opinions that by any provision hereof are specifically
required to be furnished to the Property Trustee, the Property Trustee shall be
under a duty to examine the same to determine whether or not they conform on
their face to the requirements of this Trust Agreement.

                  (c) The Property Trustee shall not be liable for any error of
judgment made in good faith by a Responsible Officer of the Property Trustee,
unless it shall be proved that the Property Trustee was grossly negligent in
ascertaining the pertinent facts.

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

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

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

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

and the Trust Indenture Act.

                  (h) The Property Trustee shall not be liable for any interest
on any money received by it except as it may otherwise agree in writing with

other funds held by it except in relation to the Property Account maintained by
the Property Trustee pursuant to Section 5.11(c)(i) and except to the extent
otherwise required by law.

                  (i) The Property Trustee shall have no duty or liability for

Convertible Debentures or the payment of any taxes or assessments levied
thereon or in connection therewith.

         Agreement, the Property Trustee shall deem it desirable that a matter
         be proved or established before taking, suffering or omitting any
         action hereunder, the Property Trustee (unless other evidence is

         include any of its employees. The Property Trustee shall have the
         right at any time to seek instructions concerning the administration
         of this Trust Agreement from any court of competent jurisdiction;

                           (vi)   the Property Trustee shall be under no
         obligation to exercise any of the rights or powers vested in it by

         complying with such request or direction, including such reasonable

         note, other evidence of indebtedness or other paper or document, but
         the Property Trustee, in its discretion, may make such further inquiry

                           (ix)   any action taken by the Property Trustee or 
         its agents hereunder shall bind the Trust and the Holders of the Trust
         Securities, and the signature of the Property Trustee or its agents
         alone shall be sufficient and effective to perform any such action and

         respect of such remedy, right or action, (B) may refrain from
         enforcing such remedy or right or taking such other action until such
         instructions are received, and (C) shall be protected in acting in
         accordance with such instructions;

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

                       (xii) the Property Trustee shall not be liable for any 
         action taken, suffered, or omitted to be taken by it in good faith and

it, in any jurisdiction in which it shall be illegal, or in which the Property
Trustee shall be unqualified or incompetent in accordance with applicable law,

                  The Certificates shall be signed on behalf of the Trust by an
Administrative Trustee. In case any Administrative Trustee who shall have
signed any of the Certificates shall cease to be such Administrative Trustee
before the Certificates so signed shall be delivered by the Trust, such
Certificates nevertheless may be delivered as though the person who signed such
Certificates had not ceased to be such Administrative Trustee; and any
Certificates may be signed on behalf of the Trust by such persons who, at the
actual date of execution of such Certificate, shall be the Administrative
Trustees of the Trust, although at the date of the execution and delivery of
the Trust Agreement any such person was not such an Administrative Trustee.
Each Preferred Security shall be dated the date of its authentication.

                  One Administrative Trustee shall sign the Preferred Security
Certificates for the Trust by manual or facsimile signature. Unless otherwise

<PAGE>   49



Clearing Agency designated by the Depositor for such Global Certificate or a
nominee thereof and delivered to such Clearing Agency or a nominee thereof or
custodian therefor, and each such Global Certificate shall constitute a
Preferred Security for all purposes of this Trust Agreement.

                  (b) If a Global Certificate is to be exchanged for
Certificated Preferred Securities or canceled in whole, it shall be surrendered
by or on behalf of the Clearing Agency, its nominee or custodian to the
Property Trustee, as Registrar, for exchange or cancellation as provided in
this Article 7. If any Global Certificate is to be exchanged for Certificated
Preferred Securities or cancelled in part, or if another Preferred Security is
to be exchanged in whole or in part for a beneficial interest in any Global
Certificate, in each case, as provided in Section 8.2, then either (i) such
Global Certificate shall be so surrendered for exchange or cancellation as
provided in this Article 7 or (ii) the principal amount thereof (or number of
Preferred Securities represented thereby) shall be reduced or increased by an
amount equal to the portion thereof to be so exchanged or cancelled, or equal
to the principal amount of (or number of securities represented by) such
Certificated Preferred Security to be so exchanged for a beneficial interest
therein, as the case may be, by means of an appropriate adjustment made on the
records of the Property Trustee, as Registrar, whereupon the Property Trustee,
in accordance with the Applicable Procedures, shall instruct the Clearing
Agency or its authorized representative to make a corresponding adjustment to
its records. Upon any such surrender or adjustment of a Global Certificate, an
Administrative Trustee shall execute on behalf of the Trust by manual or
facsimile signature, and the Property Trustee shall, subject to Section 8.2 and
as otherwise provided in this Article 7, authenticate and deliver any Preferred
Securities issuable in exchange for such Global Certificate (or any portion
thereof) to or upon the written order of, and registered in such names as may
be directed by, the Clearing Agency or its authorized representative. Upon the
request of the Property Trustee in connection with the occurrence of any of the
events specified in the preceding paragraph, the Depositor shall promptly make
available to the Property Trustee a reasonable supply of Preferred Securities
that are not in the form of Global Certificates but are in certificated form.
The Property Trustee shall be entitled to conclusively rely upon any order,
direction or request of the Clearing Agency or its authorized representative
which is given or made pursuant to this Article 7 if such order, direction or
request is given or made in accordance with the Applicable Procedures.

                  (c) Every Preferred Security authenticated and delivered upon
registration of, transfer of, or in exchange for or in lieu of, a Global
Certificate or any portion thereof, whether pursuant to this Article 7 or
otherwise, shall be authenticated and delivered in the form of, and shall



                                       43

be, a Global Certificate, unless such Preferred Security is registered in the
name of a Person other than the Clearing Agency for such Global Certificate or
a nominee thereof.

                  (d) The Clearing Agency or its nominee, as registered owner
of a Global Certificate, shall be the holder of such Global Certificate for all
purposes under this Trust Agreement and the Preferred Securities, and owners of
beneficial interests in a Global Certificate shall hold such interests pursuant
to the Applicable Procedures. Accordingly, any such Owner's beneficial interest
in a Global Certificate will be shown only on, and the transfer of such
interest shall be effected only through, records maintained by the Clearing
Agency or its nominee or its participants and such owners of beneficial
interests in a Global Certificate will not be considered the owners or holders
of such Global Certificate for any purpose of this Trust Agreement or the
Preferred Securities.

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

SECTION 7.7           Definitive Preferred Security Certificates.

                  Notwithstanding any other provision in this Trust Agreement,
no Global Certificate may be exchanged in whole or in part for Preferred
Securities registered, and no transfer of a Global Certificate in whole or in
part may be registered, in the name of any Person other than the Clearing
Agency for such Global Certificate or a nominee thereof unless (i) such
Clearing Agency (A) has notified the Trust and the Depositor that it is
unwilling or unable to continue as Clearing Agency for such Global Certificate
or (B) has ceased to be a clearing agency registered as such under the Exchange
Act of 1934, as amended, and in either case the Trust and the Depositor
thereupon fail to appoint a successor Clearing Agency, (ii) the Trust and the
Depositor, at their option, notify the Property Trustee in writing that it
elects to cause the issuance of the Preferred Securities in certificated form
or (iii) there shall have occurred and be continuing an Event of Default or any
event which after notice or lapse of time or both would be an Event of Default.
In all cases, Certificated Preferred Securities delivered in exchange for any
Global Certificate or beneficial interests therein will be registered in the
names, and issued in any approved denominations, requested by or on behalf of
the Clearing Agency (in accordance with its customary procedures).

SECTION 7.8           Restrictive Legends.

                  (a) The Restricted Global Certificate and the Certificated
Preferred Securities shall bear the following legend (the "Restricted
Securities Legend") unless the



                                       44

Depositor determines otherwise in accordance with applicable law.

             "THE SECURITIES EVIDENCED HEREBY AND THE COMMON STOCK ISSUABLE 
UPON THEIR CONVERSION AND THE CONVERTIBLE DEBENTURES THAT MAY BE ISSUED IN
EXCHANGE THEREFOR HAVE NOT BEEN REGISTERED UNDER THE U.S. SECURITIES ACT OF
1933, AS AMENDED (THE "SECURITIES ACT"), AND MAY NOT BE OFFERED, SOLD, PLEDGED
OR OTHERWISE TRANSFERRED EXCEPT (1) TO A PERSON WHO THE TRANSFEROR AND ANY
PERSON ACTING ON BEHALF OF SUCH TRANSFEROR REASONABLY BELIEVE IS A QUALIFIED
INSTITUTIONAL BUYER ACQUIRING FOR ITS OWN ACCOUNT OR THE ACCOUNT OF A QUALIFIED
INSTITUTIONAL BUYER IN A TRANSACTION COMPLYING WITH RULE 144A UNDER THE
SECURITIES ACT, (2) IN AN OFFSHORE TRANSACTION COMPLYING WITH RULE 903 OR RULE
904 OF REGULATION S UNDER THE SECURITIES ACT, (3) PURSUANT TO AN EXEMPTION FROM

AVAILABLE) OR (4) PURSUANT TO AN EFFECTIVE REGISTRATION STATEMENT UNDER THE
SECURITIES ACT AND, IN EACH CASE, IN COMPLIANCE WITH ALL APPLICABLE SECURITIES
LAWS OF THE STATES OF THE UNITED STATES AND OTHER JURISDICTIONS."

         (b) The Regulation S Preferred Securities shall bear the following
legend (the "Regulation S Legend") unless the Depositor determines otherwise in
accordance with the applicable law:

             "THE PREFERRED SECURITIES, THE CONVERTIBLE DEBENTURES, THE SHARES 
OF COMPANY COMMON STOCK ISSUABLE UPON CONVERSION OF THE PREFERRED SECURITIES

AMENDED, AND MAY NOT BE OFFERED, SOLD OR DELIVERED IN THE UNITED STATES OR TO,
OR FOR THE ACCOUNT OR BENEFIT OF, ANY U.S. PERSON UNLESS SUCH SECURITIES ARE
REGISTERED UNDER THE SECURITIES ACT OR AN EXEMPTION FROM THE REGISTRATION
REQUIREMENTS THEREOF IS AVAILABLE."

SECTION 7.9         Temporary Certificates.

             Until definitive Certificates are ready for delivery, the
Trust may prepare and, in the case of the Preferred Securities, the Property
Trustee shall authenticate temporary Certificates. Temporary Certificates shall
be substantially in the form of definitive Certificates but may have variations
that the Trust considers appropriate for temporary Certificates. Without
unreasonable delay, the Trust shall prepare and, in the case of the Preferred
Securities, the Property Trustee shall authenticate definitive Certificates in
exchange for temporary Certificates.

SECTION 7.10        Registrar, Paying Agent and Conversion Agent.
                    
             In the event that the Preferred Securities are not in book-entry 
only form, the Trust shall maintain in the



                                      45
<PAGE>   52

Borough of Manhattan, City of New York, State of New York, an office or agency
where Preferred Securities may be presented for registration of transfer or
from exchange ("Registrar"), (ii) an office or agency where Preferred
Securities may be presented for payment ("Paying Agent"). The Trust shall
maintain an office or agency where Securities may be presented for conversion
("Conversion Agent"). The Registrar shall keep a register of the Preferred
Securities and of their transfer and exchange. The Trust may appoint the
Registrar, the Paying Agent and the Conversion Agent and may appoint one or
more co- registrars, one or more additional paying agents and one or more
additional conversion agents in such other locations as it shall determine. The
term "Paying Agent" includes any additional paying agent and the term
"Conversion Agent" includes any additional conversion agent. The Trust may
change any Paying Agent, Registrar, co-registrar or Conversion Agent without
prior notice to any Holder. The Paying Agent shall be permitted to resign as
Paying Agent upon 30 days' written notice to the Administrative Trustees. The
Trust shall notify the Property Trustee of the name and address of any Agent
not a party to this Trust Agreement. If the Trust fails to appoint or maintain
another entity as Registrar, Paying Agent or Conversion Agent, the Property
Trustee shall act as such. The Trust or any of its Affiliates may act as Paying
Agent, Registrar, or Conversion Agent. The Trust shall act as Paying Agent,
Registrar, co-registrar, and Conversion Agent for the Common Securities.

                  The Trust initially appoints the Property Trustee as
Registrar, Paying Agent and Conversion Agent for the Preferred Securities. The
Property Trustee shall be entitled to the protections of Sections 5.12 and 5.13
and Article IX in its capacity as Registrar, Paying Agent and Conversion Agent.

SECTION 7.11             Paying Agent to Hold Money in Trust.
                         
                  The Trust shall require each Paying Agent other than the
Property Trustee to agree in writing that the Paying Agent will hold in trust
for the benefit of Holders or the Property Trustee all money held by the Paying
Agent for the payment of principal or distribution on the Trust Securities, and
will notify the Property Trustee if there are insufficient funds. While any
such insufficiency continues, the Property Trustee may require a Paying Agent
to pay all money held by it to the Property Trustee. The Trust at any time may
require a Paying Agent to pay all money held by it to the Property Trustee and
to account for any money disbursed by it. Upon payment over to the Property
Trustee, the Paying Agent (if other than the Trust or an Affiliate of the
Trust) shall have no further liability for the money. If the Trust or the
Depositor or an Affiliate of the Trust or the Depositor acts as Paying Agent,
it shall segregate and hold in a separate trust fund for the benefit of the
Holders all money held by it as Paying Agent.

SECTION 7.12             Outstanding Preferred Securities.

                  The Preferred Securities outstanding at any time are all the
Preferred Securities authenticated by the Property Trustee except for those
cancelled by it, those delivered to it for cancellation, and those described in
this Section 7.12 as not outstanding.

                  If a Preferred Security is replaced or paid pursuant to
Section 8.3, it ceases to be outstanding unless the Property Trustee receives
proof satisfactory to it that the replaced, paid or purchased Preferred
Security is held by a bona fide purchaser.

                  If Preferred Securities are considered paid in accordance
with the terms of this Trust Agreement, they cease to be outstanding and
interest on them ceases to accrue.

                  A Preferred Security does not cease to be outstanding because
one of the Trust, the Depositor or an Affiliate of the Depositor holds the
Preferred Security.

SECTION 7.13             Preferred Securities in Treasury.

                  In determining whether the Holders of the required amount of
Trust Securities have concurred in any direction, waiver or consent, Preferred
Securities owned by the Trust, the Depositor or an Affiliate of the Depositor,
as the case may be, shall be disregarded and deemed not to be outstanding,
except that for the purposes of determining whether the Property Trustee shall
be fully protected in relying on any such direction, waiver or consent, only
Preferred Securities which the Property Trustee knows are so owned shall be so
disregarded.

SECTION 7.14             Notices to Clearing Agency.

                  Whenever a notice or other communication to the Holders of
Preferred Securities is required under this Trust Agreement, the Administrative
Trustees shall, in the case of any Global Preferred Security, give all such
notices and communications specified herein to be given to the Preferred
Security Holders to the Depositary, and shall have no notice obligations to the
Preferred Security Beneficial Owners.

SECTION 7.15             Appointment of Successor Clearing Agency.
                         
                  If the Depositary elects to discontinue its services as
securities depositary with respect to the Preferred Securities, the
Administrative Trustees may, in their sole discretion, appoint a successor
Clearing Agency with respect to such Preferred Securities.

SECTION 7.16             Deemed Security Holders.

                  The Trustees and any Agent may treat the Person in whose name 
any Certificate shall be registered on the books



                                       47

and records of the Trust as the sole holder of such Certificate and of the
Trust Securities represented by such Certificate for purposes of receiving
Distributions and for all other purposes whatsoever and, accordingly, shall not
be bound to recognize any equitable or other claim to or interest in such
Certificate or in the Trust Securities represented by such Certificate on the
part of any Person, whether or not the Trust shall have actual or other notice
thereof.


                                  ARTICLE VIII

                     TRANSFERS, EXCHANGES AND CANCELLATIONS
                              OF TRUST SECURITIES

SECTION 8.1           General.

                  (a) Where Preferred Security Certificates are presented to
the Registrar or a co-registrar with a request to register a transfer or to
exchange them for an equal number of Preferred Securities represented by
different certificates, the Registrar shall register the transfer or make the
exchange if its requirements for such transactions are met. To permit
registrations of transfers and exchanges, the Trust shall issue and the
Property Trustee shall authenticate Preferred Security Certificates at the
Registrar's request.

                  (b) Trust Securities may only be transferred, in whole or in
part, in accordance with the terms and conditions set forth in this Trust
Agreement and in the Terms set forth in Annex I. Any transfer or purported
transfer of any Security not made in accordance with this Trust Agreement shall
be null and void.

                  (c) Subject to this Article VIII, the Depositor and any
Related Party may only transfer Common Securities to the Depositor or a Related
Party of the Depositor; provided that, any such transfer is subject to the
condition precedent that the transferor obtain the written opinion of
nationally recognized independent counsel experienced in such matters that such
transfer would not cause more than an insubstantial risk that:

                      (i)  the Trust would not be classified for United States 
         federal income tax purposes as a grantor trust; and

                      (ii) the Trust would be an Investment Company or the
         transferee would become an Investment Company.

                  (d) The Administrative Trustees shall provide for the
registration of Trust Securities and of transfers of Trust Securities, which
will be effected without charge but



                                       48

<PAGE>   55


only upon payment (with such indemnity as the Administrative Trustees may
require) in respect of any tax or other governmental charges that may be
imposed in relation to it. Upon surrender for registration of transfer of any
Certificates, the Administrative Trustees shall cause one or more new
Certificates to be issued in the name of the designated transferee or
transferees. Every Certificate surrendered for registration of transfer shall
be accompanied by a written instrument of transfer in form satisfactory to the
Administrative Trustees duly executed by the Holder or such Holder's attorney
duly authorized in writing. Each Certificate surrendered for registration of
transfer shall be canceled by the Administrative Trustees. A transferee of a
Certificate shall be entitled to the rights and subject to the obligations of a
Holder hereunder upon the receipt by such transferee of a Certificate. By
acceptance of a Certificate, each transferee shall be deemed to have agreed to
be bound by this Trust Agreement.

                  (e) The Trust shall not be required (i) to issue, register
the transfer of or exchange Preferred Security Certificates during a period
beginning at the opening of business 15 days before the day of any selection of
Preferred Securities for redemption and ending at 5:00 p.m. (New York City
time) on the day of selection, or (ii) to register the transfer or exchange of
any Preferred Security so selected for redemption in whole or in part, except
the unredeemed portion of any Preferred Security being redeemed in part.

SECTION 8.2           Certain Transfers and Exchanges.

                  (a) Notwithstanding any other provision of this Trust
Agreement or the Preferred Securities, transfers and exchanges of Preferred
Securities and beneficial interests in a Global Certificate of the kinds
specified in this Section 8.2 shall be made only in accordance with this
Section 8.2.

                      (i) Restricted Global Certificate to Regulation S Global 
         Certificate. If the owner of a beneficial interest in the Restricted
         Global Certificate wishes at any time to transfer such interest to a

         interest in the Regulation S Global Certificate, such transfer may be
         effected in accordance with provision of this Clause 8.2(i) and Clause
         8.2 (vi) below and subject to the Applicable Procedures. Upon receipt
         by the Property Trustee, as Registrar, of (A) a written order given by
         the Clearing Agency or its authorized representative directing that a
         beneficial interest in the Regulation S Global Certificate in a
         specified liquidation amount (or number of Preferred Securities) be
         credited to a



                                       49
<PAGE>   56



         specified participant's account and that a beneficial interest in the
         Restricted Global Certificate in an equal liquidation amount (or
         number of Preferred Securities) be debited from another specified
         participant's account and (B) a Regulation S Certificate, satisfactory
         to the Property Trustee and duly executed by the owner of such
         beneficial interest in the Restricted Global Certificate or his
         attorney duly authorized in writing, then the Property Trustee, as
         Registrar but subject to Clause 8.2 (vi) below, shall reduce the share
         number of the Restricted Global certificate and increase the share
         number of the Regulation S Global Certificate by such specified
         liquidation amount (or number of Preferred Securities) as provided in
         Section 7.6(b).

                           (ii)  Regulation S Global Certificate to Restricted
         Global Certificate. If the owner of a beneficial interest in the
         Regulation S Global Certificate wishes at any time to transfer such
         interest to a Person who wishes to acquire the same in the form of a
         beneficial interest in the Restricted Global Certificate, such
         transfer may be effected only in accordance with this Clause 8.2(ii)
         and subject to the Applicable Procedures. Upon receipt by the Property
         Trustee, as Registrar, of (A) a written order given by the Clearing
         Agency or its authorized representative directing that a beneficial
         interest in the Restricted Global Certificate in a specified
         Liquidation Amount (or number of Preferred Securities) be credited to
         a specified participant's account and that a beneficial interest in
         the Regulation S Global Certificate in an equal liquidation amount (or
         number of Preferred Securities) be debited from another specified
         participant's account and (B) if such transfer is to occur during the
         Restricted Period, a Restricted Securities Certificate, satisfactory
         to the Property Trustee and duly executed by the owner of such
         beneficial interest in the Regulation S Global certificate or his
         attorney duly authorized in writing, then the Property Trustee, as
         Registrar, shall reduce the liquidation amount (or number of Preferred
         Securities) of the Regulation S Global Certificate and increase the
         liquidation amount of (or number of Preferred Securities represented
         by) the Restricted Global Certificate by such specified liquidation
         amount (or number of securities) as provided in Section 7.6(b).

                           (iii) Restricted Non-Global Certificate to 
         Restricted Global Certificate or Regulation S Global Certificate. If
         the Holder of a Restricted Security (other than a Global Certificate)
         wishes at any time to transfer all or any portion of such Restricted
         Security



                                       50
<PAGE>   57



         to a Person who wishes to take delivery thereof in the form of a
         beneficial interest in the Restricted Global Certificate or the
         Regulation S Global Certificate, such transfer may be effected only in
         accordance with the provisions of this Clause 8.2 (iii) and Clause 8.2
         (vi) below and subject to the Applicable Procedures. Upon receipt by
         the Property Trustee, as Registrar, of (A) such Restricted Security as
         provided in Section 7.6 and written instructions satisfactory to the
         Property Trustee directing that a beneficial interest in the
         Restricted Global Certificate or Regulation S Global Certificate in a
         specified liquidation amount (or number of Preferred Securities) not
         greater than the amount of such Preferred Security be credited to a
         specified participant's account and (B) a Restricted Securities
         Certificate, if the specified account is to be credited with a
         beneficial interest in the Restricted Global Certificate, or a
         Regulation S Certificate, if the specified account is to be credited
         with a beneficial interest in the Regulation S Global Certificate, in
         either case satisfactory to the Property Trustee and duly executed by
         such Holder or his attorney duly authorized in writing, then the
         Property Trustee, as Registrar but subject to Clause 8.2 (vi) below,
         shall cancel such Restricted Security (and issue a new Restricted
         Security in respect of any untransferred portion thereof) as provided
         in Section 7.6(b) and increase the liquidation amount of (or number of
         Preferred Securities represented by) the Restricted Global Certificate
         or the Regulation S Global Certificate, as the case may be, by the
         specified liquidation amount (or number of securities) as provided in
         Section 7.6(b).

                           (iv) Regulation S Non-Global Certificate to
         Restricted Global Certificate or Regulation S Global Certificate. If
         the Holder of a Regulation S Preferred Security (other than a Global
         Certificate) wishes at any time to transfer all or any portion of such
         Regulation S Preferred Security to a Person who wishes to acquire the
         same in the form of a beneficial interest in the Restricted Global
         Certificate or the Regulation S Global Certificate, such transfer may
         be effected only in accordance with this Clause 8.2(iv) and Clause
         8.2(vi) below and subject to the Applicable Procedures. Upon receipt
         by the Property Trustee, as Registrar, of (A) such Regulation S
         Preferred Security and written instructions satisfactory to the
         Property Trustee directing that a beneficial interest in the
         Restricted Global Certificate or Regulation S Global Certificate in a
         specified liquidation amount (or number of Preferred Securities) not
         greater than the amount of such Preferred Security be credited to a
         specified participant's account and (B) if the transfer



                                       51

<PAGE>   58



         is to occur during the Restricted Period and the specified account to
         be credited with a beneficial interest in the Restricted Global
         Certificate, a Restricted Securities Certificate satisfactory to the
         Property Trustee and duly executed by such Holder or his attorney duly
         authorized in writing then the Property Trustee, as Registrar but
         subject to Clause 8.2(vi) below, shall cancel such Regulation S
         Preferred Security (and issue a new Regulation S Preferred Security in
         respect of any untransferred portion thereof) as provided in Section
         7.6(b) and increase the liquidation amount of (or number of Preferred
         Securities represented by) the Restricted Global Certificate or the
         Regulation S Global Certificate, as the case may be, by the specified
         liquidation amount (or number of securities) as provided in Section
         7.6(b).

                           (v)  Non-Global Certificate to Non-Global 
         Certificate. A Preferred Security that is not a Global Certificate may
         be transferred, in whole or in part, to a Person who takes delivery in
         the form of another Security that is not a Global Certificate as
         provided in Section 7.6, provided that, if the Security to be
         transferred in whole or in part is a Restricted Security, or is a
         Regulation S Preferred Security and the transfer is to occur during
         the Restricted Period, then the Property Trustee shall have received
         (A) a Restricted Securities Certificate, satisfactory to the Property
         Trustee and duly executed by the transferor Holder or his attorney
         duly authorized in writing, in which case the transferee Holder shall
         take delivery in the form of a Restricted Security, or (B) a
         Regulation S Certificate, satisfactory to the Property Trustee and
         duly executed by the transferor Holder or his attorney duly authorized
         in writing, in which case the transferee Holder shall take delivery in
         the form of a Regulation S Preferred Security (subject in every case
         to Section 8.2(b)).

                           (vi) Regulation S Global Certificate to be Held
         Through Euroclear or Cedal during Restricted Period. The Depositor
         shall use its best efforts to cause the Clearing Agency to ensure
         that, until the expiration of the Restricted Period, beneficial
         interests in the Regulation S Global Certificate may be held only in
         or through accounts maintained at the Clearing Agency by Euroclear or
         Cedel (or by participants acting for the account thereof), and no
         Person shall be entitled to effect any transfer or exchange that would
         result in any such interest being held otherwise than in or through
         such an account; provided that this Clause 8.2(vi) shall not prohibit
         any transfer or exchange of such an interest in



                                       52

         accordance with Clause 8.2(iii) or (iv) above.

                  (b) Securities Act Legends. Rule 144A Securities,
Certificated Preferred Securities and their respective Successor Securities
shall bear a Restricted Securities Legend as set forth in Section 7.8, and the
Regulation S Preferred Securities and their Successor Securities shall bear a
Regulation S Legend as set forth in Section 7.8, subject to the following:

                      (i)   subject to the following Clauses of this Section
         8.2(b), a Preferred Security or any portion thereof which is
         exchanged, upon transfer or otherwise, for a Global Certificate or any
         portion thereof shall bear the Securities Act Legend borne by such
         Global Certificate while represented thereby;

                      (ii)  subject to the following Clauses of this Section 
         8.2(b), a new Preferred Security which is not a Global Certificate and
         is issued in exchange for another Preferred Security (including, a
         Global Certificate) of any portion thereof, upon transfer or
         otherwise, shall bear the Securities Act Legend borne by such other
         Preferred Security, provided that, if such new Preferred Security is
         required pursuant to Section 8.2(a)(v) to be issued in the form of a
         Restricted Security, it shall bear a Restricted Securities Legend and,
         if such new Preferred Security is so required to be issued in the form
         of a Regulation S Preferred Security, it shall bear a Regulation S
         Legend;

                      (iii) Any Preferred Securities which are sold or 
         otherwise disposed of pursuant to an effective registration statement
         under the Securities Act, together with their Successor Securities
         shall not bear a Securities Act Legend; the Depositor shall inform the
         Property Trustee in writing of the effective date of any such
         registration statement registering the Preferred Securities under the
         Securities Act and shall notify the Property Trustee at any time when
         prospectuses may not be delivered with respect to Preferred Securities
         to be sold pursuant to such registration statement. The Property
         Trustee shall not be liable for any action taken or omitted to be
         taken by it in good faith in accordance with the aforementioned
         registration statement;

                      (iv)  at any time after the Preferred Securities may be 
         freely transferred without registration under the Securities Act or
         without being subject to transfer restrictions pursuant to the
         Securities Act, a new Preferred Security which does not bear a
         Securities Act Legend may be issued in exchange for or in lieu of a
         Preferred Security (other than a



                                       53
<PAGE>   60



         Global Certificate) or any portion thereof which bears such a legend
         if the Property Trustee has received an Unrestricted Securities
         Certificate, satisfactory to the Property Trustee and duly executed by
         the Holder of such legended Preferred Security or his attorney duly
         authorized in writing, and after such date and receipt of such
         certificate, an Administrative Trustee shall execute on behalf of the
         Trust by manual or facsimile signature, and the Property Trustee shall
         authenticate and deliver such a new Preferred Security in exchange for
         or in lieu of such other Preferred Security as provided in this
         Article 8;

                      (v)  a new Preferred Security which does not bear a
         Securities Act Legend may be issued in exchange for or in lieu of a
         Preferred Security (other than a Global Certificate) or any portion
         thereof which bears such a legend if, in the Depositor's judgment,
         placing such a legend upon such new Preferred Security is not
         necessary to ensure compliance with the registration requirements of
         the Securities Act, and an Administrative Trustee shall execute on
         behalf of the Trust by manual or facsimile signature, and the Property
         Trustee, at the written direction of the Depositor, shall authenticate
         and deliver such a new Preferred Security as provided in this Article
         8; and

                      (vi) notwithstanding the foregoing provisions of this 
         Section 8.2(b), a Successor Security of a Preferred Securities that
         does not bear a particular form of Securities Act Legend shall not
         bear such form of legend unless the Depositor has reasonable cause to
         believe that such Successor Security is a "restricted security" within
         the meaning of Rule 144, in which case an Administrative Trustee shall
         execute on behalf of the Trust by manual or facsimile signature, and
         the Property Trustee, at the written direction of the Depositor, shall
         authenticate and deliver a new Preferred Security bearing a Restricted
         Securities Legend in exchange for such Successor Security as provided
         in this Article 8.

SECTION 8.3           Mutilated, Destroyed, Lost or Stolen Certificates; 
                      Replacement Securities.

                  If the holder of a Trust Security claims that the Certificate
representing such Trust Security has been lost, destroyed or wrongfully taken
or if such Certificate is mutilated and is surrendered to the Trust or in the
case of the Preferred Securities to the Property Trustee, the Trust shall issue
and the Property Trustee shall authenticate a replacement Certificate if the
Property Trustee's and the Trust's requirements, as the case may be, are met.
If required by the Property Trustee or the Trust, an indemnity bond must be
sufficient in the judgment of both to protect



                                       54
<PAGE>   61

the Trustees, the Property Trustee, the Depositor or any authenticating agent
from any loss which any of them may suffer if a Certificate is replaced. The
Company may charge for its expenses in replacing a Certificate.

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

                  Every replacement Certificate is an additional obligation of
the Trust.

SECTION 8.4           Cancellation of Preferred Security Certificates.

                  The Trust at any time may deliver Preferred Security
Certificates to the Property Trustee for cancellation. The Registrar, Paying
Agent and Conversion Agent shall forward to the Property Trustee any Preferred
Securities surrendered to them for registration of transfer, redemption,
conversion, exchange or payment. The Property Trustee shall promptly cancel all
Preferred Securities surrendered for registration of transfer, redemption,
conversion, exchange, payment, replacement or cancellation and shall dispose of
cancelled Preferred Securities as the Trust directs. The Trust may not issue
new Preferred Securities to replace Preferred Securities that it has paid or
that have been delivered to the Property Trustee for cancellation or that any
holder has converted.


                                   ARTICLE IX

                           LIMITATION OF LIABILITY OF
                HOLDERS OF TRUST SECURITIES, TRUSTEES AND OTHERS

SECTION 9.1       Liability.

              (a) Except as expressly set forth in this Trust Agreement, the 
Securities Guarantees and the terms of the Trust Securities, the Depositor
shall not be:

                  (i)  personally liable for the return of any portion of the 
         capital contributions (or any return thereon) of the Holders of the 
         Trust Securities which shall be made solely from assets of the Trust; 
         or

                  (ii) required to pay to the Trust or to any Holder of Trust 
         Securities any deficit upon dissolution of the Trust or otherwise.

              (b) The Depositor shall be liable for all of the debts and
obligations of the Trust (other than with respect



                                       55
<PAGE>   62



to the Trust Securities) to the extent not satisfied out of the Trust's assets.

               (c) Pursuant to ss. 3803(a) of the Business Trust Act, the
Holders of the Preferred Securities shall be entitled to the same limitation of
personal liability as is extended to stockholders of private corporations for
profit organized under the General Corporation Law of the State of Delaware.

SECTION 9.2              Exculpation.

               (a) No Indemnified Person shall be liable, responsible or
accountable in damages or otherwise to the Trust or any Covered Person for any
loss, damage or claim incurred by reason of any act or omission performed or
omitted by such Indemnified Person in good faith on behalf of the Trust and in
a manner such Indemnified Person reasonably believed to be within the scope of
the authority conferred on such Indemnified Person by this Trust Agreement or
by law, except that an Indemnified Person shall be liable for any such loss,
damage or claim incurred by reason of such Indemnified Person's gross
negligence or willful misconduct with respect to such acts or omissions.

               (b) An Indemnified Person shall be fully protected in relying in 
good faith upon the records of the Trust and upon such information, opinions,
reports or statements presented to the Trust by any Person as to matters the
Indemnified Person reasonably believes are within such other Person's
professional or expert competence and who has been selected with reasonable
care by or on behalf of the Trust, including information, opinions, reports or
statements as to the value and amount of the assets, liabilities, profits,
losses, or any other facts pertinent to the existence and amount of assets from
which Distributions to Holders of Trust Securities might properly be paid.

SECTION 9.3              Fiduciary Duty.

               (a)  To the extent that, at law or in equity, an Indemnified
Person has duties (including fiduciary duties) and liabilities relating thereto
to the Trust or to any other Covered Person, an Indemnified Person acting under
this Trust Agreement shall not be liable to the Trust or to any other Covered
Person for its good faith reliance on the provisions of this Trust Agreement.
The provisions of this Trust Agreement, to the extent that they restrict the
duties and liabilities of an Indemnified Person otherwise existing at law or in
equity (other than the duties imposed on the Property Trustee under the Trust
Indenture Act), are agreed by the parties hereto to replace such other duties
and liabilities of such Indemnified Person.

<PAGE>   63



               (b) Unless otherwise expressly provided herein:

                   (i)  whenever a conflict of interest exists or arises 
         between an Indemnified Person and any Covered Person or

                   (ii) whenever this Trust Agreement or any other agreement 
         contemplated herein or therein provides that an Indemnified Person
         shall act in a manner that is, or provides terms that are, fair and
         reasonable to the Trust or any Holder of Trust Securities,

the Indemnified Person shall resolve such conflict of interest, take such
action or provide such terms, considering in each case the relative interest of
each party (including its own interest) to such conflict, agreement,
transaction or situation and the benefits and burdens relating to such
interests, any customary or accepted industry practices, and any applicable
generally accepted accounting practices or principles. In the absence of bad
faith by the Indemnified Person, the resolution, action or term so made, taken
or provided by the Indemnified Person shall not constitute a breach of this
Trust Agreement or any other agreement contemplated herein or of any duty or
obligation of the Indemnified Person at law or in equity or otherwise.

               (c) Whenever in this Trust Agreement an Indemnified Person is
permitted or required to make a decision:

                   (i)  in its "discretion" or under a grant of similar         
          authority, the Indemnified Person shall be entitled to consider such
         interests and factors as it desires, including its own interests, and
         shall have no duty or obligation to give any consideration to any
         interest of or factors affecting the Trust or any other Person; or

                   (ii) in its "good faith" or under another express standard, 
         the Indemnified Person shall act under such express standard and shall
         not be subject to any other or different standard imposed by this
         Trust Agreement or by applicable law.

SECTION 9.4        Indemnification.

               (a) (i) The Company shall indemnify, to the full extent 
         permitted by law, any Company Indemnified Person who was or is a party
         or is threatened to be made a party to any threatened, pending or
         completed action, suit or proceeding, whether civil, criminal,
         administrative or investigative (other than an action by or in the
         right of the Trust) by reason of the fact that he is or was a Company
         Indemnified Person against



                                       57
<PAGE>   64



         expenses (including attorneys' fees), judgments, fines and amounts
         paid in settlement actually and reasonably incurred by him in
         connection with such action, suit or proceeding if he acted in good
         faith and in a manner he reasonably believed to be in or not opposed
         to the best interests of the Trust, and, with respect to any criminal
         action or proceeding, had no reasonable cause to believe his conduct
         was unlawful. The termination of any action, suit or proceeding by
         judgment, order, settlement, conviction, or upon a plea of nolo
         contendere or its equivalent, shall not, of itself, create a
         presumption that the Company Indemnified Person did not act in good
         faith and in a manner which he reasonably believed to be in or not
         opposed to the best interests of the Trust, and, with respect to any
         criminal action or proceeding, had reasonable cause to believe that
         his conduct was unlawful.

                  (ii)  The Company shall indemnify, to the full extent
         permitted by law, any Company Indemnified Person who was or is a party
         or is threatened to be made a party to any threatened, pending or
         completed action or suit by or in the right of the Trust to procure a
         judgment in its favor by reason of the fact that he is or was a
         Company Indemnified Person against expenses (including attorneys'
         fees) actually and reasonably incurred by him in connection with the
         defense or settlement of such action or suit if he acted in good faith
         and in a manner he reasonably believed to be in or not opposed to the
         best interests of the Trust and except that no such indemnification
         shall be made in respect of any claim, issue or matter as to which
         such Company Indemnified Person shall have been adjudged to be liable
         to the Trust unless and only to the extent that the Court of Chancery
         of Delaware or the court in which such action or suit was brought
         shall determine upon application that, despite the adjudication of
         liability but in view of all the circumstances of the case, such
         person is fairly and reasonably entitled to indemnity for such
         expenses which such Court of Chancery or such other court shall deem
         proper.

                  (iii) To the extent that a Company Indemnified Person shall
         be successful on the merits or otherwise (including dismissal of an
         action without prejudice or the settlement of an action without
         admission of liability) in defense of any action, suit or proceeding
         referred to in paragraphs (i) and (ii) of this Section 9.4(a), or in
         defense of any claim, issue or matter therein, he shall be
         indemnified, to the full extent permitted by law, against expenses
         (including attorneys' fees) actually and reasonably incurred by him in
         connection therewith.



                                       58
<PAGE>   65



                  (iv) Any indemnification under paragraphs (i) and (ii) of
         this Section 9.4(a) (unless ordered by a court) shall be made by the
         Company only as authorized in the specific case upon a determination
         that indemnification of the Company Indemnified Person is proper in
         the circumstances because he has met the applicable standard of
         conduct set forth in paragraphs (i) and (ii). Such determination shall
         be made (1) by the Administrative Trustees by a majority vote of a
         quorum consisting of such Administrative Trustees who were not parties
         to such action, suit or proceeding, (2) if such a quorum is not
         obtainable, or, even if obtainable, if a quorum of disinterested
         Administrative Trustees so directs, by independent legal counsel in a
         written opinion, or (3) by the Holders of the Common Securities of the
         Trust.

                  (v)  Expenses (including attorneys' fees) incurred by a
         Company Indemnified Person in defending a civil, criminal,
         administrative or investigative action, suit or proceeding referred to
         in paragraphs (i) and (ii) of this Section 9.4(a) shall be paid by the
         Company in advance of the final disposition of such action, suit or
         proceeding upon receipt of an undertaking by or on behalf of such
         Company Indemnified Person to repay such amount if it shall ultimately
         be determined that he is not entitled to be indemnified by the Company
         as authorized in this Section 9.4(a). Notwithstanding the foregoing,
         no advance shall be made by the Company if a determination is
         reasonably and promptly made (i) by the Administrative Trustees by a
         majority vote of a quorum of disinterested Administrative Trustees,
         (ii) if such a quorum is not obtainable, or, even if obtainable, if a
         quorum of disinterested Administrative Trustees so directs, by
         independent legal counsel in a written opinion or (iii) by the Holders
         of the Common Securities of the Trust, that, based upon the facts
         known to the Administrative Trustees, counsel or the Holders of the
         Common Securities at the time such determination is made, such Company
         Indemnified Person acted in bad faith or in a manner that such person
         did not believe to be in or not opposed to the best interests of the
         Trust, or, with respect to any criminal proceeding, that such Company
         Indemnified Person believed or had reasonable cause to believe his
         conduct was unlawful. In no event shall any advance be made in
         instances where the Administrative Trustees, independent legal counsel
         or the Holders of the Common Securities reasonably determine that such
         person deliberately breached his duty to the Trust or the Holders of
         the Common or Preferred Securities.

                  (vi) The indemnification and advancement of expenses provided
         by, or granted pursuant to, the other paragraphs of this Section
         9.4(a) shall not be deemed



                                       59

<PAGE>   66



         exclusive of any other rights to which those seeking indemnification
         and advancement of expenses may be entitled under any agreement, vote
         of stockholders or disinterested directors of the Company or Holders
         of the Preferred Securities of the Trust or otherwise, both as to
         action in his official capacity and as to action in another capacity
         while holding such office. All rights to indemnification under this
         Section 9.4(a) shall be deemed to be provided by a contract between
         the Company and each Company Indemnified Person who serves in such
         capacity at any time while this Section 9.4(a) is in effect. Any
         repeal or modification of this Section 9.4(a) shall not affect any
         rights or obligations then existing.

                  (vii)  The Company or the Trust may purchase and maintain
         insurance on behalf of any person who is or was a Company Indemnified
         Person against any liability asserted against him and incurred by him
         in any such capacity, or arising out of his status as such, whether or
         not the Company would have the power to indemnify him against such
         liability under the provisions of this Section 9.4(a).

                  (viii) For purposes of this Section 9.4(a), references to
         "the Trust" shall include, in addition to the resulting or surviving
         entity, any constituent entity (including any constituent of a
         constituent) absorbed in a consolidation or merger, so that any person
         who is or was a director, trustee, officer or employee of such
         constituent entity, or is or was serving at the request of such
         constituent entity as a director, trustee, officer, employee or agent
         of another entity, shall stand in the same position under the
         provisions of this Section 9.4(a) with respect to the resulting or
         surviving entity as he would have with respect to such constituent
         entity if its separate existence had continued.

                  (ix)   The indemnification and advancement of expenses 
         provided by, or granted pursuant to, this Section 9.4(a) shall, unless
         otherwise provided when authorized or ratified, continue as to a
         person who has ceased to be a Company Indemnified Person and shall
         inure to the benefit of the heirs, executors and administrators of
         such a person.

         (b) The Depositor agrees to indemnify the (i) Property Trustee, (ii)
the Delaware Trustee, (iii) any Affiliate of the Property Trustee and the
Delaware Trustee, and (iv) any officers, directors, shareholders, members,
partners, employees, representatives, custodians, nominees or agents of the
Property Trustee and the Delaware Trustee (each of the Persons in (i) through
(iv) being referred to as a "Fiduciary Indemnified Person") for, and to hold
each



                                       60

<PAGE>   67



Fiduciary Indemnified Person harmless against, any and all loss, liability or
expense including taxes (other than taxes based on the income of such Fiduciary
Indemnified Person) incurred without gross negligence or bad faith on its part,
arising out of or in connection with the acceptance or administration or the
trust or trusts hereunder, including the costs and expenses (including
reasonable legal fees and expenses) of defending itself against or
investigating any claim or liability in connection with the exercise or
performance of any of its powers or duties hereunder. The obligation to
indemnify as set forth in this Section 9.4(b) shall survive the satisfaction
and discharge of this Trust Agreement.

SECTION 9.5         Outside Businesses.

               Any Covered Person, the Depositor, the Delaware Trustee and
its Affiliates and the Property Trustee and its Affiliates may engage in or
possess an interest in other business ventures of any nature or description,
independently or with others, similar or dissimilar to the business of the
Trust, and the Trust and the Holders of Trust Securities shall have no rights
by virtue of this Trust Agreement in and to such independent ventures or the
income or profits derived therefrom, and the pursuit of any such venture, even
if competitive with the business of the Trust, shall not be deemed wrongful or
improper. No Covered Person, the Depositor, the Delaware Trustee, its
Affiliates, or the Property Trustee or its Affiliates shall be obligated to
present any particular investment or other opportunity to the Trust even if
such opportunity is of a character that, if presented to the Trust, could be
taken by the Trust, and any Covered Person, the Depositor, the Delaware
Trustee, its Affiliates and the Property Trustee and its Affiliates shall have
the right to take for its own account (individually or as a partner or
fiduciary) or to recommend to others any such particular investment or other
opportunity. Any Covered Person, the Delaware Trustee, its Affiliates and the
Property Trustee and its Affiliates may engage or be interested in any
financial or other transaction with the Depositor or any Affiliate of the
Depositor, or may act as depositary for, trustee or agent for, or act on any
committee or body of holders of, securities or other obligations of the
Depositor or its Affiliates.

of the Administrative Trustees.

SECTION 10.2          Certain Accounting Matters.

                  (a) At all times during the existence of the Trust, the
Administrative Trustees shall keep, or cause to be kept, full books of account,
records and supporting documents, which shall reflect in reasonable detail,
each transaction of the Trust. The books of account shall be maintained on the
accrual method of accounting, in accordance with generally accepted accounting
principles, consistently applied. The Trust shall use the accrual method of
accounting for United States federal income tax purposes. The books of account
and the records of the Trust shall be examined by and reported upon as of the
end of each Fiscal Year by a firm of independent certified public accountants
selected by the Administrative Trustees.

                  (b) The Administrative Trustees shall cause to be prepared
and delivered to each of the Holders of Trust Securities, within 90 days after

Trust, including a balance sheet of the Trust as of the end of such Fiscal
Year, and the related statements of income or loss;

                  (c) The Administrative Trustees shall cause to be duly
prepared and delivered to each of the Holders of Trust Securities, any annual
United States federal income tax information statement required by the Code,
containing such information with regard to the Trust Securities held by each
Holder as is required by the Code and the Treasury Regulations. Notwithstanding
any right under the Code to deliver any such statement at a later date, the
Administrative Trustees shall endeavor to deliver all such statements within 30
days after the end of each Fiscal Year of the Trust.

                  (d) The Administrative Trustees shall cause to be duly
prepared and filed with the appropriate taxing authority, an annual United
States federal income tax return, on a Form 1041 or such other form required by
the Code, and any other annual income tax returns required to be filed by the
Administrative Trustees on behalf of the Trust with any state or local taxing

SECTION 10.3          Banking.

                  The Trust shall maintain one or more bank accounts in the
name and for the sole benefit of the Trust; provided, however, that all
payments of funds in respect of the Convertible Debentures held by the Property
Trustee shall be made directly to the Property Account and no other funds of
the Trust shall be deposited in the Property Account. The sole signatories for
such accounts shall be designated by



                                       62

the Administrative Trustees; provided, however, that the Property Trustee shall

SECTION 10.4         Withholding.

                  The Trust and the Administrative Trustees shall comply with
all withholding requirements under United States federal, state and local law.
The Trust shall request, and the Holders shall provide to the Trust, such forms
or certificates as are necessary to establish an exemption from withholding
with respect to each Holder, and any representations and forms as shall
reasonably be requested by the Trust to assist it in determining the extent of,
and in fulfilling, its withholding obligations. The Administrative Trustee
shall file required forms with applicable jurisdictions and, unless an
exemption from withholding is properly established by a Holder, shall remit
amounts withheld with respect to the Holder to applicable jurisdictions. To the
extent that the Trust is required to withhold and pay over any amounts to any
authority with respect to distributions or allocations to any Holder, the
amount withheld shall be deemed to be a distribution in the amount of the
withholding to the Holder. In the event of any claimed overwithholding, Holders
shall be limited to an action against the applicable jurisdiction. If the
amount required to be withheld was not withheld from actual Distributions made,
the Trust may reduce subsequent Distributions by the amount of such
withholding.

SECTION 11.2          Meetings of the Holders of Trust Securities; Action by 
                      Written Consent.

                  (a) Meetings of the Holders of any class of Trust Securities
may be called at any time by the Administrative Trustees (or as provided in the
terms of the Trust Securities) to consider and act on any matter on which
Holders of such class of Trust Securities are entitled to act under the terms
of this Trust Agreement, the terms of the Trust Securities or the rules of any
stock exchange on which the Preferred Securities are listed or admitted for
trading. The Administrative Trustees shall call a meeting of the Holders of
such class if directed to do so by the Holders of at least 10% in liquidation
amount of such class of Trust Securities. Such direction shall be given by
delivering to the Administrative Trustees one or more calls in a writing
stating that the signing Holders of Trust Securities wish to call a meeting and
indicating the general or specific purpose for which the meeting is to be
called. Any Holders of Trust Securities calling a meeting shall specify in
writing the Certificates held by the Holders of Trust Securities exercising the
right to call a meeting and only those Trust Securities represented by the
Certificates so specified shall be counted for purposes of determining whether
the required percentage set forth in the second sentence of this paragraph has

                  (b) Except to the extent otherwise provided in the terms of
the Trust Securities, the following provisions shall apply to meetings of

<PAGE>   72



                           (i)   notice of any such meeting shall be given to 
         all the Holders of Trust Securities having a right to vote thereat at
         least seven days and not more than 60 days before the date of such
         meeting. Whenever a vote, consent or approval of the Holders of Trust
         Securities is permitted or required under this Trust Agreement or the
         rules of any stock exchange or over-the-counter market on which the
         Preferred Securities are listed or admitted for trading, such vote,
         consent or approval may be given at a meeting of the Holders of Trust
         Securities. Any action that may be taken at a meeting of the Holders
         of Trust Securities may be taken without a meeting if a consent in
         writing setting forth the action so taken is signed by the Holders of
         Trust Securities owning not less than the minimum amount of Trust
         Securities in liquidation amount that would be necessary to authorize
         or take such action at a meeting at which all Holders of Trust
         Securities having a right to vote thereon were present and voting.
         Prompt notice of the taking of action without a meeting shall be given
         to the Holders of Trust Securities entitled to vote who have not
         consented in writing. The Administrative Trustees may specify that any
         written ballot submitted to the Security Holders for the purpose of
         taking any action without a meeting shall be returned to the Trust
         within the time specified by the Administrative Trustees;

                           (ii)  each Holder of a Security may authorize any
         Person to act for it by proxy on all matters in which a Holder of
         Trust Securities is entitled to participate, including waiving notice
         of any meeting, or voting or participating at a meeting. No proxy
         shall be valid after the expiration of 11 months from the date thereof
         unless otherwise provided in the proxy. Every proxy shall be revocable
         at the pleasure of the Holder of Trust Securities executing it. Except
         as otherwise provided herein, all matters relating to the giving,
         voting or validity of proxies shall be governed by the General
         Corporation Law of the State of Delaware relating to proxies, and
         judicial interpretations thereunder, as if the Trust were a Delaware
         corporation and the Holders of the Trust Securities were stockholders
         of a Delaware corporation;

                           (iii) each meeting of the Holders of the Trust
         Securities shall be conducted by the Administrative Trustees or by
         such other Person that the Administrative Trustees may designate; and

                           (iv)  unless the Business Trust Act, this Trust
         Agreement, the terms of the Trust Securities, the Trust Indenture Act
         or the listing rules of any stock exchange on which the Preferred
         Securities are then listed or trading provide otherwise, the
         Administrative

         Trustees, in their sole discretion, shall establish all other
         provisions relating to meetings of Holders of Trust Securities,
         including notice of the time, place or purpose of any meeting at which
         any matter is to be voted on by any Holders of Trust Securities,
         waiver of any such notice, action by consent without a meeting, the
         establishment of a record date, quorum requirements, voting in person
         or by proxy or any other matter with respect to the exercise of any
         such right to vote.

                                  ARTICLE XIII

                                   CONVERSION

SECTION 13.1       Conversion Rights.

               The holders of Trust Securities shall have the right at any
time prior to 5:00 p.m. (New York City time) on the Business Day immediately
preceding the date of repayment of such Trust Securities, whether at maturity
or upon redemption (either at the option of the Company or pursuant to a Tax
Event), at their option, to cause the Conversion Agent to convert Trust
Securities, on behalf of the converting Holders, into shares of Company Common
Stock of the Company in the manner described herein on and subject to the
following terms and conditions:

               The Trust Securities will be convertible at the office of the
Conversion Agent into fully paid and nonassessable shares of Company Common
Stock of the Company pursuant to the Holder's direction to the Conversion Agent
to exchange such Trust Securities for a portion of the Convertible Debentures
theretofore held by the Trust on the basis of one Trust Security per $25
principal amount of Convertible Debentures, and immediately convert such amount
of Convertible Debentures into fully paid and nonassessable shares of Company
Common Stock of the Company at an initial conversion rate of 0.4545 shares of
Company Common Stock of the Company per $25 principal amount of Convertible
Debentures (which is equivalent to a conversion price of $55.00 per share of
Company Common Stock of the Company, subject to certain adjustments set forth
in this Article Thirteen (as so adjusted, the "Conversion Price")).

SECTION 13.2       Conversion Procedures.

               (a) In order to convert Trust Securities into Company Common
Stock, the Holder shall submit to the Conversion Agent an irrevocable request
to convert Trust Securities on behalf of such Holder (the "Conversion
Request"), together, if the Trust Securities are in certificated form, with
such certificates. The Conversion Request shall (i) set forth the number of
Trust Securities to be converted and the name or names, if other than the
Holder, in which the shares of Company Common Stock of the Company should be
issued and (ii) direct the Conversion Agent (A) to exchange such Trust
Securities for a portion of the Convertible Debentures held by the Trust (at
the rate of exchange specified in Section 13.1) and (B) to immediately convert
such Convertible Debentures on behalf of such Holder, into Company Common Stock
of the Company (at the conversion rate specified in Section 13.1).

               (b) The Conversion Agent shall notify the Trust of the Holder's 
election to exchange Trust Securities for a portion of the Convertible
Debentures held by the Trust and the Trust shall, upon receipt of such notice,
deliver to the Conversion Agent the appropriate principal amount of Convertible
Debentures for exchange in accordance with this



                                       70
<PAGE>   77

Article Thirteen. The Conversion Agent shall thereupon notify the Company of
the Holder's election to convert such Convertible Debentures into shares of
Company Common Stock of the Company. Accrued Distributions will not be paid on
Preferred Trust Securities that are converted, nor will any payment, allowance
or adjustment be made for accumulated and unpaid Distributions, whether or not
in arrears, on converted Preferred Securities except that if any Preferred
Security is converted (i) on or after a record date for payment of
Distributions thereon, the Distributions payable on the related payment date
with respect to such Preferred Security shall be distributed to the Holder on
such record date, despite such conversion, and (ii) during an Extension Period
and after the Property Trustee mails a Redemption Distribution Notice with
respect to the Preferred Securities that are converted, accrued and unpaid
Distributions through the date of conversion on such Preferred Securities
called for redemption shall be distributed to the Holder who converts such
Preferred Securities, which Distribution shall be made on the redemption date
fixed for redemption. Except as provided above, neither the Trust nor the
Company will make, or be required to make, any payment, allowance or adjustment
upon any conversion on account of any accumulated and unpaid Distributions
accrued on the Trust Securities (including any Additional Interest, Compounded
Interest or Liquidated Damages, if any) surrendered for conversion, or on
account of any accumulated and unpaid dividends on the shares of Company Common
Stock of the Company issued upon such conversion. The Company shall make no
payment or allowance for distributions on the shares of Company Common Stock of
the Company issued upon such conversion, except to the extent that such shares
of Company Common Stock of the Company are held of record on the record date
for any such distributions and except as provided in Section 1309 of the
Indenture. Trust Securities shall be deemed to have been converted immediately
prior to 5:00 p.m. (New York City time) on the day on which a Conversion
Request relating to such Trust Securities is received by the Trust in
accordance with the foregoing provision (the "Conversion Date"). The Person or
Persons entitled to receive the Company Common Stock of the Company issuable
upon conversion of the Convertible Debentures shall be treated for all purposes
as the record holder or holders of such Company Common Stock of the Company at
such time. As promptly as practicable on or after the Conversion Date, the
Company shall issue and deliver at the office of the Conversion Agent a
certificate or certificates for the number of full shares of Company Common
Stock of the Company issuable upon such conversion, together with the cash
payment, if any, in lieu of any fraction of any share to the Person or Persons
entitled to receive the same, unless otherwise directed by the Holder in the
notice of conversion and the Conversion Agent shall distribute such certificate
or certificates to such Person or Persons.

<PAGE>   78



                  (c) Each Holder of a Security by his acceptance thereof
appoints Chase Bank of Texas, National Association (the "Conversion Agent") for
the purpose of effecting the conversion of Trust Securities in accordance with
this Article Thirteen. In effecting the conversion and transactions described
in this Article Thirteen, the Conversion Agent shall be acting as agent of the
Holders of Trust Securities directing it to effect such conversion
transactions. The Conversion Agent is hereby authorized (i) to exchange Trust
Securities from time to time for Convertible Debentures held by the Trust in
connection with the conversion of such Trust Securities in accordance with this
Article Thirteen and (ii) to convert all or a portion of the Convertible
Debentures into Company Common Stock of the Company and thereupon to deliver
such shares of Company Common Stock of the Company in accordance with the
provisions of this Article Thirteen and to deliver to the Trust a new Debenture
or Convertible Debentures for any resulting unconverted principal amount.

                  (d) No fractional shares of Company Common Stock of the
Company will be issued as a result of conversion, but in lieu thereof such
fractional interest will be in cash (based on the last reported sale price of
the Company Common Stock of the Company on the Conversion Date) by the Company
to the Trust, which in turn will make such payment to the Holder or Holders of
Trust Securities so converted.

                  (e) The Company shall at all times reserve and keep available
out of its authorized and unissued Company Common Stock, solely for issuance
upon the conversion of the Convertible Debentures, free from any preemptive or
other similar rights, such number of shares of Company Common Stock of the
Company as shall from time to time be issuable upon the conversion of all the
Convertible Debentures then outstanding. Notwithstanding the foregoing, the
Company shall be entitled to deliver upon conversion of Convertible Debentures,
shares of Company Common Stock of the Company reacquired and held in the
treasury of the Company (in lieu of the issuance of authorized and unissued
shares of Company Common Stock of the Company), so long as any such treasury
shares are free and clear of all liens, charges, security interests or
encumbrances. Any shares of Company Common Stock issued upon conversion of the
Convertible Debentures shall be duly authorized, validly issued, fully paid and
nonassessable. The Trust shall deliver the shares of Company Common Stock
received upon conversion of the Convertible Debentures to the converting Holder
free and clear of all liens, charges, security interests and encumbrances,
except for United States withholding taxes. Each of the Company and the Trust
shall prepare and shall use its best efforts to obtain and keep in force such
governmental or regulatory permits or other authorizations as may be required
by law, and shall comply with all applicable requirements as to registration or
qualification



                                       72

<PAGE>   79

of the Company Common Stock (and all requirements to list the Company Common
Stock issuable upon conversion of Convertible Debentures that are at the time
applicable), in order to enable the Company to lawfully issue Company Common
Stock to the Trust upon conversion of the Convertible Debentures and the Trust
to lawfully deliver the Company Common Stock to each Holder upon conversion of
the Trust Securities.

                  (f) The Company will pay any and all taxes that may be
payable in respect of the issue or delivery of shares of Company Common Stock
on conversion of Convertible Debentures and the delivery of the shares of
Company Common Stock by the Trust upon conversion of the Trust Securities. The
Company shall not, however, be required to pay any tax that may be payable in
respect of any transfer involved in the issue and delivery of shares of Company
Common Stock in a name other than that in which the Trust Securities so
converted were registered, and no such issue or delivery shall be made unless
and until the person requesting such issue has paid to the Trust the amount of
any such tax or has established to the satisfaction of the Trust that such tax
has been paid.

                  (g) Nothing in the preceding Article Thirteen shall limit the
requirement of the Trust to withhold taxes pursuant to the terms of the Trust
Securities or as set forth in Annex I to the Trust Agreement or this agreement
or otherwise require the Property Trustee or the Trust to pay any amounts on
account of such withholdings.

SECTION 13.3          Conversion Price Adjustments.

                  The conversion price shall be subject to adjustment (without
duplication) from time to time as follows:

                  (a) In case the Company shall, while any of the Trust
Securities are outstanding, (i) pay a dividend or make a distribution with
respect to its Company Common Stock in shares of Company Common Stock, (ii)
subdivide its outstanding shares of Company Common Stock, (iii) combine its
outstanding shares of Company Common Stock into a smaller number of shares or
(iv) issue by reclassification of its shares of Company Common Stock any shares
of capital stock of the Company, the conversion price in effect immediately
prior to such action shall be adjusted so that the Holder of any Trust
Securities thereafter surrendered for conversion shall be entitled to receive
the number of shares of capital stock of the Company which he would have owned
immediately following such action had such Trust Securities been converted
immediately prior thereto. An adjustment made pursuant to this Section 13.3(a)
shall become effective immediately after the record date in the case of a
dividend or other distribution and shall become



                                       73

<PAGE>   80



effective immediately after the effective date in case of a subdivision,
combination or reclassification (or immediately after the record date if a
record date shall have been established for such event). If, as a result of an
adjustment made pursuant to this Section 13.3(a), the Holder of any Trust
Securities thereafter surrendered for conversion shall become entitled to
receive shares of two or more classes or series of capital stock of the
Company, the Board of Directors (whose determination shall be conclusive and
shall be described in a Board Resolution filed with the Trustee) shall
determine the allocation of the adjusted conversion price between or among
shares of such classes or series of capital stock.

                  (b) In case the Company shall, while any of the Trust
Securities are outstanding, issue rights or warrants to all holders of its
Company Common Stock entitling them (for a period expiring within 45 days after
the record date mentioned in this Section 13.3(b)) to subscribe for or purchase
shares of Company Common Stock at a price per share less than the current
market price per share of Company Common Stock (as determined pursuant to
Section 13.3(f) below) on such record date, the conversion price for the Trust
Securities shall be adjusted so that the same shall equal the price determined
by multiplying the conversion price in effect immediately prior to the date of
issuance of such rights or warrants by a fraction of which the numerator shall
be the number of shares of Company Common Stock outstanding on the date of
issuance of such rights or warrants plus the number of shares which the
aggregate offering price of the total number of shares so offered for
subscription or purchase would purchase at such current market price, and of
which the denominator shall be the number of shares of Company Common Stock
outstanding on the date of issuance of such rights or warrants plus the number
of additional shares of Company Common Stock offered for subscription or
purchase. Such adjustment shall become effective immediately after the record
date for the determination of stockholders entitled to receive such rights or
warrants. For the purposes of this subsection, the number of shares of Company
Common Stock at any time outstanding shall not include shares held in the
treasury of the Company. The Company shall not issue any rights or warrants in
respect of shares of Company Common Stock held in the treasury of the Company.
In case any rights or warrants referred to in this subsection in respect of
which an adjustment shall have been made shall expire unexercised within 45
days after the same shall have been distributed or issued by the Company, the
conversion price shall be readjusted at the time of such expiration to the
conversion price that would have been in effect if no adjustment had been made
on account of the distribution or issuance of such expired rights or warrants.



                                      74
<PAGE>   81


                  (c) Subject to the last sentence of this Section 13.3(c), in 
case the Company shall, by dividend or otherwise, distribute to all holders of
its Company Common Stock evidences of its indebtedness, shares of any class or
series of capital stock, cash or assets (including securities, but excluding
any rights or warrants referred to in Section 13.3(b), any dividend or
distribution paid exclusively in cash and any dividend or distribution referred
to in Section 13.3(a)), the conversion price shall be reduced so that the same
shall equal the price determined by multiplying the conversion price in effect
immediately prior to the effectiveness of the conversion price reduction
contemplated by this Section 13.3(c) by a fraction of which the numerator shall
be the current market price per share (determined as provided in Section
13.3(f)) of the Company Common Stock on the date fixed for the payment of such
distribution (the "Reference Date") less the fair market value (as determined
in good faith by the Board of Directors, whose determination shall be
conclusive and described in a resolution of the Board of Directors), on the
Reference Date, of the portion of the evidences of indebtedness, shares of
capital stock, cash and assets so distributed applicable to one share of
Company Common Stock and the denominator shall be such current market price per
share of the Company Common Stock, such reduction to become effective
immediately prior to the opening of business on the day following the Reference
Date. In the event that such dividend or distribution is not so paid or made,
the conversion price shall again be adjusted to be the conversion price which
would then be in effect if such dividend or distribution had not occurred. If
the Board of Directors determines the fair market value of any distribution for
purposes of this Section 13.3(c) by reference to the actual or when issued
trading market for any securities comprising such distribution, it must in
doing so consider the prices in such market over the same period used in
computing the current market price per share of Company Common Stock
(determined as provided in Section 13.3(f)). For purposes of this Section
13.3(c), any dividend or distribution that includes shares of Company Common
Stock or rights or warrants to subscribe for or purchase shares of Company
Common Stock shall be deemed instead to be (1) a dividend or distribution of
the evidences of indebtedness, shares of capital stock, cash or assets other
than such shares of Company Common Stock or such rights or warrants (making any
conversion price reduction required by this Section 13.3(c)) immediately
followed by (2) a dividend or distribution of such shares of Company Common
Stock or such rights or warrants (making any further conversion price reduction
required by Section 13.3(a) or 13.3(b)), except (A) the Reference Date of such
dividend or distribution as defined in this Section 13.3(c) shall be
substituted as (a) "the record date in the case of a dividend or other
distribution," and (b) "the record date for the determination of stockholders
entitled to receive such rights or warrants" and (c) "the date fixed for such



                                       75
<PAGE>   82



determination" within the meaning of Sections 13.3(a) and 13.3(b) and (B) any
shares of Company Common Stock included in such dividend or distribution shall
not be deemed outstanding for purposes of computing any adjustment of the
conversion price in Section 13.3(a).

                  (d) In case the Company shall pay or make a dividend or other
distribution on its Company Common Stock exclusively in cash (excluding all
regular cash dividends, if the annualized amount thereof per share of Company
Common Stock does not exceed 20% of the current market price per share
determined as provided in Section 13.3(f) of the Company Common Stock on the
Trading Day immediately preceding the date of declaration of such dividend),
the conversion price shall be reduced so that the same shall equal the price
determined by multiplying the conversion price in effect immediately prior to
the effectiveness of the conversion price reduction contemplated by this
Section 13.3(d) by a fraction of which the numerator shall be the current
market price per share (determined as provided in Section 13.3(f)) of the
Company Common Stock on the date fixed for the payment of such distribution
less the amount of cash so distributed and not excluded as provided applicable
to one share of Company Common Stock and the denominator shall be such current
market price per share of the Company Common Stock, such reduction to become
effective immediately prior to the opening of business on the day following the
date fixed for the payment of such distribution; provided, however, that in the
event the portion of the cash so distributed applicable to one share of Company
Common Stock is equal to or greater than the current market price per share (as
defined in Section 13.3(f)) of the Company Common Stock on the record date
mentioned above, in lieu of the foregoing adjustment, adequate provision shall
be made so that each Holder of Trust Securities shall have the right to receive
upon conversion the amount of cash such Holder would have received had such
Holder converted each share of the Trust Securities immediately prior to the
record date for the distribution of the cash. In the event that such dividend
or distribution is not so paid or made, the conversion price shall again be
adjusted to be the conversion price which would then be in effect if such
record date had not been fixed.

                  (e) In case a tender or exchange offer (other than an odd-lot
offer) made by the Company or any Subsidiary of the Company for all or any
portion of the Company's Company Common Stock shall expire and such tender or
exchange offer shall involve the payment by the Company or such Subsidiary of
consideration per share of Company Common Stock having a fair market value (as
determined in good faith by the Board of Directors, whose determination shall
be conclusive and described in a resolution of the Board of Directors) at the
last time (the "Expiration Time") tenders



                                       76
<PAGE>   83



or exchanges may be made pursuant to such tender or exchange offer (as it shall
have been amended) that exceeds 110% of the current market price per share
(determined as provided in Section 13.3(f)) of the Company Common Stock on the
Trading Day next succeeding the Expiration Time, the conversion price shall be
reduced so that the same shall equal the price determined by multiplying the
conversion price in effect immediately prior to the effectiveness of the
conversion price reduction contemplated by this Section 13.3(e) by a fraction
of which the numerator shall be the number of shares of Company Common Stock
outstanding (including any tendered or exchanged shares) at the Expiration Time
multiplied by the current market price per share (determined as provided in
Section 13.3(f)) of the Company Common Stock on the Trading Day next succeeding
the Expiration Time and the denominator shall be the sum of (x) the fair market
value (determined as aforesaid) of the aggregate consideration payable to
stockholders based on the acceptance (up to any maximum specified in the terms
of the tender or exchange offer) of all shares validly tendered or exchanged
and not withdrawn as of the Expiration Time (the shares deemed so accepted, up
to any such maximum, being referred to as the "Purchased Shares") and (y) the
product of the number of shares of Company Common Stock outstanding (less any
Purchased Shares) at the Expiration Time and the current market price per share
(determined as provided in Section 13.3(f)) of the Company Common Stock on the
Trading Day next succeeding the Expiration Time, such reduction to become
effective immediately prior to the opening of business on the day following the
Expiration Time.

                  (f) For the purpose of any computation under Section 13.3(b),
13.3(c), 13.3(d) or 13.3(e), the current market price per share of Company
Common Stock on any date in question shall be deemed to be the average of the
daily Closing Prices for the five consecutive Trading Days selected by the
Company commencing not more than 20 Trading Days before, and ending not later
than, the earlier of the day in question or, if applicable, the day before the
"ex" date with respect to the issuance or distribution requiring such
computation; provided, however, that if another event occurs that would require
an adjustment pursuant to Section 13.3(a) through (e), inclusive, the Board of
Directors may make such adjustments to the Closing Prices during such five
Trading Day period as it deems appropriate to effectuate the intent of the
adjustments in this Section 13.3, in which case any such determination by the
Board of Directors shall be set forth in a Board Resolution and shall be
conclusive. For purposes of this paragraph, the term "ex" date, (i) when used
with respect to any issuance or distribution, means the first date on which the
Company Common Stock trades regular way on the New York Stock Exchange or on
such successor securities exchange as the Company Common Stock may be listed or
in the relevant market from which the Closing Prices were obtained without the
right to receive such



                                       77
<PAGE>   84



issuance or distribution, and (ii) when used with respect to any tender or
exchange offer, means the first date on which the Company Common Stock trades
regular way on such securities exchange or in such market after the Expiration
Time of such offer.

                  (g) The Company may make such reductions in the conversion
price, in addition to those required by Sections 13.3(a) through (e), as it
considers to be advisable to avoid or diminish any income tax to holders of
Company Common Stock or rights to purchase Company Common Stock resulting from
any dividend or distribution of stock (or rights to acquire stock) or from any
event treated as such for income tax purposes. The Company from time to time
may reduce the conversion price by any amount for any period of time if the
period is at least 20 days, the reduction is irrevocable during the period, and
the Board of Directors of the Company shall have made a determination that such
reduction would be in the best interest of the Company, which determination
shall be conclusive. Whenever the conversion price is reduced pursuant to the
preceding sentence, the Company shall mail to holders of record of the
Convertible Debentures a notice of the reduction at least 15 days prior to the
date the reduced conversion price takes effect, and such notice shall state the
reduced conversion price and the period it will be in effect.

                  (h) No adjustment in the conversion price shall be required
unless such adjustment would require an increase or decrease of at least 1% in
the conversion price; provided, however, that any adjustments which by reason
of this Section 13.3(h) are not required to be made shall be carried forward
and taken into account in determining whether any subsequent adjustment shall
be required.

                  (i) If any action would require adjustment of the conversion
price pursuant to more than one of the provisions described above, only one
adjustment shall be made and such adjustment shall be the amount of adjustment
that has the highest absolute value to the Holder of the Trust Securities.

SECTION 13.4          Fundamental Change.

                  (a) In the event that the Company is party to any transaction
(including, without limitation, a merger other than a merger that does not
result in a reclassification, conversion, exchange or cancellation of Company
Common Stock), consolidation, sale of all or substantially all of the assets of
the Company, recapitalization or reclassification of Company Common Stock
(other than a change in par value, or from par value to no par value, or from
no par value to par value or as a result of a subdivision or combination of
Company Common Stock) or any compulsory share exchange (each of the foregoing
being



                                       78
<PAGE>   85



referred to as a "Transaction"), in each case, as a result of which shares of
Company Common Stock shall be converted into the right to receive, or shall be
exchanged for, (i) in the case of any Transaction other than a Transaction
involving a Common Stock Fundamental Change (and subject to funds being legally
available for such purpose under applicable law at the time of such
conversion), securities, cash or other property, each Preferred Security shall
thereafter be convertible into the kind and, in the case of a Transaction which
does not involve a Fundamental Change, amount of securities, cash and other
property receivable upon the consummation of such Transaction by a holder of
that number of shares of Company Common Stock into which a Preferred Security
was convertible immediately prior to such Transaction, or (ii) in the case of a
Transaction involving a Common Stock Fundamental Change, common stock, each
Preferred Security shall thereafter be convertible (in the manner described
therein) into common stock of the kind received by holders of Company Common
Stock (but in each case after giving effect to any adjustment discussed below
relating to a Fundamental Change if such Transaction constitutes a Fundamental
Change). The holders of Preferred Securities will have no voting rights with
respect to any Transaction.

                  (b) If any Fundamental Change occurs, then the conversion
price in effect will be adjusted immediately after such Fundamental Change as
described below. In addition, in the event of a Common Stock Fundamental
Change, each Preferred Security shall be convertible solely into common stock
of the kind received by holders of Company Common Stock as a result of such
Common Stock Fundamental Change.

                  (c) The conversion price in the case of any Transaction
involving a Fundamental Change will be adjusted immediately after such
Fundamental Change:

                      (i)  in the case of a Non-Stock Fundamental Change, the 
                  conversion price of the Preferred Securities will thereupon
                  become the lower of (A) the conversion price in effect
                  immediately prior to such Non-Stock Fundamental Change, but
                  after giving effect to any other prior adjustments effected
                  pursuant to the preceding paragraphs, and (B) the greater of
                  the Applicable Price or the then applicable Reference Market
                  Price plus any then-accrued and unpaid distributions on one
                  Preferred Security; and

                      (ii) in the case of a Common Stock Fundamental Change, 
                  the conversion price of the Preferred Securities in effect
                  immediately prior to such Common Stock Fundamental Change,
                  but after giving effect to any other prior adjustments



                                       79
<PAGE>   86



                  effected pursuant to the preceding paragraphs, will thereupon
                  be adjusted by multiplying such conversion price by a
                  fraction of which the numerator will be the Purchaser Stock
                  Price and the denominator will be the Applicable Price;
                  provided, however, that in the event of a Common Stock
                  Fundamental Change in which (A) 100% of the value of the
                  consideration received by a holder of Company Common Stock is
                  common stock of the successor, acquirer, or other third party
                  (and cash, if any, is paid only with respect to any
                  fractional interests in such common stock resulting from such
                  Common Stock Fundamental Change) and (B) all Company Common
                  Stock will be have been exchanged for, converted into, or
                  acquired for common stock (and cash with respect to
                  fractional interests) of the successor, acquirer, or other
                  third party, the conversion price of the Preferred Securities
                  in effect immediately prior to such Common Stock Fundamental
                  Change will thereupon be adjusted by multiplying such
                  conversion price by a fraction of which the numerator will be
                  one and the denominator will be the number of shares of
                  common stock of the successor, acquirer, or other third party
                  received by a holder of one share of Company Common Stock as
                  a result of such Common Stock Fundamental Change.

                  The Company or the Person formed by such consolidation or
resulting from such merger or which acquired such assets or which acquires the
Company's shares, as the case may be, shall make provision in its certificate
or articles of incorporation or other constituent document to establish such
right. Such certificate or articles of incorporation or other constituent
document shall provide for adjustments which, for events subsequent to the
effective date of such certificate or articles of incorporation or other
constituent document, shall be as nearly equivalent as may be practicable to
the adjustments provided for in this Article Thirteen. The above provisions
shall similarly apply to successive transactions of the foregoing type.

SECTION 13.5             Notice of Adjustments of Conversion Price.
                         
                  Whenever the conversion price is adjusted as herein provided:

                  (a) the Company shall compute the adjusted Conversion Price
and shall prepare a certificate signed by the Chief Financial Officer or the
Treasurer of the Company setting forth the adjusted Conversion Price and
showing in reasonable detail the facts upon which such adjustment is based, and
such certificate shall forthwith be filed with



                                       80
<PAGE>   87

the Trustee, the Conversion Agent and the transfer agent for the Preferred
Securities and the Convertible Debentures; and

                  (b) a notice stating the Conversion Price has been adjusted
and setting forth the adjusted Conversion Price shall as soon as practicable be
mailed by the Company to all record holders of Preferred Securities and the
Convertible Debentures at their last addresses as they appear upon the stock
transfer books of the Company and the Trust.

SECTION 13.6          Prior Notice of Certain Events.
                      

                  In case:

                  (a) the Company shall (i) declare any dividend (or any other
distribution) on its Company Common Stock, other than (A) a dividend payable in
shares of Company Common Stock or (B) a dividend payable in cash that would not
require an adjustment pursuant to Section 13.3(c) or 13.3(d), or (ii) authorize
a tender or exchange offer that would require an adjustment pursuant to Section
13.3(e);

                  (b) the Company shall authorize the granting to all holders
of Company Common Stock of rights or warrants to subscribe for or purchase any
shares of stock of any class or series or of any other rights or warrants;

of any reclassification of Company Common Stock (other than a subdivision or
combination of the outstanding Company Common Stock, or a change in par value,
or from par value to no par value, or from no par value to par value), or of
any consolidation or merger to which the Company is a party and for which
approval of any stockholders of the Company shall be required, or of the sale
or transfer of all or substantially all of the assets of the Company or of any
compulsory share exchange whereby the Company Common Stock is converted into
other securities, cash or other property; or

                  (c)      of the voluntary or involuntary dissolution,
liquidation or winding up of the Company;

then the Company shall (1) if any Preferred Securities are outstanding, cause
to be filed with the transfer agent for the Preferred Securities, and shall
cause to be mailed to the holders of record of the Preferred Securities, at
their last addresses as they shall appear upon the stock transfer books the
Trust or (2) shall cause to be mailed to all Holders at their last addresses as
they shall appear in the Security Register, at least 15 days prior to the
applicable record or effective date hereinafter specified, a notice stating (x)
the date on which a record (if any) is to be taken for the purpose of such
dividend, distribution, rights or warrants or, if a record is not to be taken,
the date as



                                       81
<PAGE>   88


of which the holders of Company Common Stock of record to be entitled to such
dividend, distribution, rights or warrants are to be determined or (y) the date
on which such reclassification, consolidation, merger, sale, transfer, share
exchange, dissolution, liquidation or winding up is expected to become
effective, and the date as of which it is expected that holders of Company
Common Stock of record shall be entitled to exchange their shares of Company
Common Stock for securities, cash or other property deliverable upon such
reclassification, consolidation, merger, sale, transfer, share exchange,
dissolution, liquidation or winding up (but no failure to mail such notice or
any defect therein or in the mailing thereof shall affect the validity of the
corporate action required to be specified in such notice).

SECTION 13.7          Certain Defined Terms.

                  The following definitions shall apply to terms used in this
Article Thirteen:

                  (a) "Closing Price" of any Company Common Stock on any day
shall mean the reported last sale price on such day or in case no sale takes
place on such day, the average of the reported closing bid and asked prices in
each case on the NYSE Consolidated Transactions Tape or, if the stock is not
listed or admitted to trading on the NYSE, on the principal national securities
exchange on which such stock is listed or admitted to trading or, if not listed
or admitted to trading on any national securities exchange, the average of the
closing bid and asked prices as furnished by any NYSE member firm, selected by
the Debenture Trustee for that purpose.

                  (b) "Trading Day" shall mean a day on which securities are
traded on the national securities exchange or quotation system used to
determine the Closing Price.

SECTION 13.8          Certain Additional Rights.

                  In case the Company shall, by dividend or otherwise, declare
or make a distribution on its Company Common Stock referred to in Section
13.3(c) or 13.3(d) (including, without limitation, dividends or distributions
referred to in the last sentence of Section 13.3(c)), the Holder of the Trust
Securities, upon the conversion thereof subsequent to 5:00 p.m. (New York City
time) on the date fixed for the determination of stockholders entitled to
receive such distribution and prior to the effectiveness of the conversion
price adjustment in respect of such distribution, shall also be entitled to
receive for each share of Company Common Stock into which the Trust Securities
are converted, the portion of the shares of Company Common Stock, rights,
warrants, evidences of indebtedness, shares of capital stock, cash and assets
so



                                       82
<PAGE>   89



distributed applicable to one share of Company Common Stock; provided, however,
that, at the election of the Company (whose election shall be evidenced by a
resolution of the Board of Directors) with respect to all Holders so
converting, the Company may, in lieu of distributing to such Holder any portion
of such distribution not consisting of cash or securities of the Company, pay
such Holder an amount in cash equal to the fair market value thereof (as
determined in good faith by the Board of Directors, whose determination shall
be conclusive and described in a resolution of the Board of Directors). If any
conversion of Trust Securities described in the immediately preceding sentence
occurs prior to the payment date for a distribution to holders of Company
Common Stock which the Holder of Trust Securities so converted is entitled to
receive in accordance with the immediately preceding sentence, the Company may
elect (such election to be evidenced by a resolution of the Board of Directors)
to distribute to such Holder a due bill for the shares of Company Common Stock,
rights, warrants, evidences of indebtedness, shares of capital stock, cash or
assets to which such Holder is so entitled, provided, that such due bill (i)
meets any applicable requirements of the principal national securities exchange
or other market on which the Company Common Stock is then traded and (ii)
requires payment or delivery of such shares of Company Common Stock, rights,
warrants, evidences of indebtedness, shares of capital stock, cash or assets no
later than the date of payment or delivery thereof to holders of shares of
Company Common Stock receiving such distribution.

SECTION 13.9          Restrictions on Company Common Stock Issuable Upon 
                      Conversion.

                  (a) Shares of Company Common Stock to be issued upon
conversion of a Trust Security in respect of Restricted Preferred Securities
shall bear such restrictive legends as the Company may provide in accordance
with applicable law.

                  (b) If shares of Company Common Stock to be issued upon
conversion of a Trust Security in respect of Restricted Preferred Securities
are to be registered in a name other than that of the Holder of such Preferred
Security, then the Person in whose name such shares of Company Common Stock are
to be registered must deliver to the Conversion Agent a certificate
satisfactory to the Company and signed by such Person, as to compliance with
the restrictions on transfer applicable to such Preferred Security. Neither the
Trustee nor any Conversion Agent or Registrar shall be required to register in
a name other than that of the Holder shares of Company Common Stock issued upon
conversion of any such Trust Security in respect of such Preferred Securities
not so accompanied by a properly completed certificate.

SECTION 13.10          Trustee Not Responsible for Determining Conversion Price 
                       or Adjustments.

                  Neither the Trustee nor any Conversion Agent shall at any
time be under any duty or responsibility to any Holder of any Trust Security to
determine whether any facts exist which may require any adjustment of the
conversion price, or with respect to the nature or extent of any such
adjustment when made, or with respect to the method employed, or herein or in
any supplemental indenture provided to be employed, in making the same. Neither
the Trustee nor any Conversion Agent shall be accountable with respect to the
validity or value (or the kind of account) of any shares of Company Common
Stock or of any securities or property, which may at any time be issued or
delivered upon the conversion of any Trust Security; and neither the Trustee
nor any Conversion Agent makes any representation with respect thereto. Neither
the Trustee nor any Conversion Agent shall be responsible for any failure of
the Company to make any cash payment or to issue, transfer or deliver any
shares of Company Common Stock or stock certificates or other securities or
property upon the surrender of any Trust Security for the purpose of
conversion, or, except as expressly herein provided, to comply with any of the
covenants of the Company contained in this Article Thirteen.

                                                                         ANNEX I

                                    TERMS OF
              5 1/4% CONVERTIBLE TRUST ISSUED PREFERRED SECURITIES
                      5 1/4% CONVERTIBLE COMMON SECURITIES



                  Pursuant to Section 7.1 of the Amended and Restated
Declaration of Trust, dated as of March 18, 1998 (as amended from time to time,
the "Trust Agreement"), the designation, rights, privileges, restrictions,
preferences and other terms and provisions of the Preferred Securities and the
Common Securities are set out below (each capitalized term used but not defined
herein has the meaning set forth in the Trust Agreement):

1.       Designation and Number.

         (a)      "Preferred Securities":  4,000,000 5 1/4% ConvertibLE
                  Trust Issued Preferred Securities of the Trust
                  with a liquidation amount of $25 per Preferred
                  Security, plus up to an additional 400,000
                  Preferred Securities of the Trust with a
                  liquidation amount of $25 per Preferred Security,
                  solely to cover over-allotments, if any, as
                  provided for in the Purchase Agreement (the
                  "Additional Preferred Securities"), are hereby
                  designated for the purposes of identification only
                  as "5 1/4% Convertible Trust Issued Preferred
                  Securities (liquidation amount of $25 per
                  Preferred Security)" (the "Preferred Securities").
                  The Preferred Security Certificates evidencing the
                  Preferred Securities shall be substantially in the
                  form of Exhibit A-1 to the Trust Agreement, with
                  such changes and additions thereto or deletions
                  therefrom as may be required by ordinary usage,
                  custom or practice or to conform to the rules of
                  any stock exchange or other organization on which
                  the Preferred Securities are listed.

         (b)      "Common Securities":  123,711 Common Securities of
                  the Trust with a liquidation amount of $25 per
                  Common Security, plus up to an additional 12,371



<PAGE>   98



                  Common Securities of the Trust with a liquidation amount of
                  $25 per Common Security to meet the capital requirements of
                  the Trust in the event of an issuance of Additional Preferred
                  Securities, if any, are hereby designated for the purposes of
                  identification only as "5 1/4% Convertible Common Securities
                  (liquidation amount of $25 per Common Security)" (the "Common
                  Securities"). The Common Security Certificates evidencing the
                  Common Securities shall be substantially in the form of
                  Exhibit A-2 to the Trust Agreement, with such changes and
                  additions thereto or deletions therefrom as may be required by
                  ordinary usage, custom or practice.

2.       Distributions.

         (a)      Distributions payable on each Trust Security will
                  be fixed at a rate per annum of 5 1/4% (the "Coupon
                  Rate") of the stated liquidation amount of $25 per
                  Security, such rate being the rate of interest
                  payable on the Convertible Debentures to be held
                  by the Property Trustee.  Distributions in arrears
                  for more than one quarter will bear interest
                  thereon compounded quarterly at the Coupon Rate
                  (to the extent permitted by applicable law).  The
                  term "Distributions" as used herein includes any
                  such interest including any Additional Interest,
                  Compounded Interest and Liquidated Damages (all as
                  defined in the Trust Agreement), if any, payable
                  unless otherwise stated.  A Distribution is
                  payable only to the extent that payments are made
                  in respect of the Convertible Debentures held by
                  the Property Trustee and to the extent the Trust
                  has funds available therefor.  The amount of
                  Distributions payable for any period will be
                  computed for any full quarterly Distribution
                  period on the basis of a 360-day year of twelve
                  30-day months, and for any period shorter than a
                  full quarterly Distribution period for which
                  Distributions are computed, Distributions will be
                  computed on the basis of the actual number of days
                  elapsed per 90-day quarter.

         (b)      Except as otherwise described below, Distributions on the
                  Trust Securities will be cumulative, will accrue from the date
                  of initial issuance and will be payable quarterly in arrears,
                  on the following


                                       I-2


<PAGE>   99



                  dates, which dates correspond to the interest payment dates on
                  the Convertible Debentures: January 1, April 1, July 1 and
                  October 1 of each year, commencing on July 1, 1998, when, as
                  and if available for payment by the Property Trustee. Provided
                  that no Event of Default has occurred and is continuing, the
                  Company has the right at any time during the term of the
                  Convertible Debentures to defer interest payments from time to
                  time by extending the interest payment period for successive
                  periods not exceeding 20 consecutive quarters (each an
                  "Extension Period") for each such period; provided, that no
                  Extension Period may extend beyond the maturity date of the
                  Convertible Debentures. As a consequence of such extension,
                  quarterly Distributions on the Trust Securities would be
                  deferred (though such Distributions would continue to accrue
                  with interest since interest would continue to accrue on the
                  Convertible Debentures) during any such extended interest
                  payment period. In the event that the Company exercises this
                  right, then, during such period the Company has agreed, among
                  other things, (a) not to declare or pay dividends on, or make
                  a distribution with respect to, or redeem or purchase or
                  acquire, or make a liquidation payment with respect to, any of
                  its capital stock (other than (i) purchases or acquisitions of
                  shares of Company Common Stock in connection with the
                  satisfaction by the Company of its obligations under any
                  employee benefit plans or the satisfaction by the Company of
                  its obligations pursuant to any contract or security requiring
                  the Company to purchase shares of Company Common Stock, (ii)
                  as a result of a reclassification of the Company's capital
                  stock or the exchange or conversion of one class or series of
                  the Company's capital stock for another class or series of the
                  Company's capital stock or (iii) the purchase of fractional
                  interests in shares of the Company's capital stock pursuant to
                  the conversion or exchange provisions of such capital stock or
                  the security being converted or exchanged) or make any
                  guarantee payments with respect to the foregoing, (b) not to
                  make any payment of interest, principal or premium, if any, on
                  or repay, repurchase or redeem any debt securities (including
                  guarantees) issued by the Company that rank pari passu with or
                  junior to the


                                       I-3


<PAGE>   100



                  Convertible Debentures and (c) not to make any guarantee
                  payments with respect to the foregoing (other than pursuant to
                  the Preferred Securities Guarantee). Prior to the termination
                  of any such Extension Period, the Company may further extend
                  the interest payment period; provided, that such Extension
                  Period, together with all such previous and further extensions
                  thereof, may not exceed 20 consecutive quarters or extend
                  beyond the maturity date of the Convertible Debentures. Upon
                  the termination of any Extension Period and the payment of all
                  amounts then due, the Company may commence a new Extension
                  Period, subject to the above requirements.

         (c)      Distributions on the Trust Securities will be
                  payable to the Holders thereof as they appear on
                  the books and records of the Trust on the relevant
                  record dates.  The relevant record dates shall be
                  the March 15, June 15, September 15 and December
                  15 prior to the next succeeding payment dates,
                  except as otherwise described in this Annex I to
                  the Trust Agreement.  Subject to any applicable
                  laws and regulations and the provisions of the
                  Trust Agreement, each such payment in respect of
                  the Preferred Securities being held in book-entry
                  form through The Depository Trust Company (the
                  "Depositary") will be made as described under the
                  heading "Description of the Preferred Securities
                  -- Book-Entry Only Issuance - The Depository Trust
                  Company" in the Offering Memorandum.  The relevant
                  record dates for the Common Securities shall be
                  the same record dates as for the Preferred
                  Securities.  Distributions payable on any Trust
                  Securities that are not punctually paid on any
                  Distribution payment date as a result of the
                  Company having failed to make a payment under the
                  Convertible Debentures, will cease to be payable
                  to the Person in whose name such Trust Securities
                  are registered on the relevant record date, and
                  such defaulted Distribution will instead be
                  payable to the Person in whose name such Trust
                  Securities are registered on the special record
                  date or other specified date determined in
                  accordance with the Indenture.  If Distributions
                  are deferred, the deferred Distributions and
                  accrued interest thereon shall be paid to the
                  holders of record of Trust Securities as they
                  appear on the books and records of the Trust on


                                       I-4


<PAGE>   101



                  the record date next following the termination of such
                  deferral period. If any date on which Distributions are
                  payable on the Trust Securities is not a Business Day, then
                  payment of the Distribution payable on such date will be made
                  on the next succeeding day that is a Business Day (and without
                  any distribution or other payment in respect of any such
                  delay) except that, if such Business Day is in the next
                  succeeding calendar year, such payment shall be made on the
                  immediately preceding Business Day, in each case with the same
                  force and effect as if made on such date.

         (d)      In the event of an election by the Holder to
                  convert its Trust Securities through the
                  Conversion Agent into Company Common Stock of the
                  Company pursuant to the terms of the Trust
                  Securities as set forth in this Annex I to the
                  Trust Agreement, accrued Distributions will not be
                  paid on Preferred Securities that are converted,
                  nor will any payment, allowance or adjustment be
                  made for accumulated and unpaid Distributions,
                  whether or not in arrears, on converted Preferred
                  Securities except that if any Preferred Security
                  is converted on or after a record date for payment
                  of Distributions thereon, the Distributions
                  payable on the related payment date with respect
                  to such Preferred Security shall be distributed to
                  the Holder on such record date, despite such
                  conversion.

         (e)      In the event that there is any money or other property held by
                  or for the Trust that is not accounted for hereunder, such
                  property shall be distributed Pro Rata (as defined in
                  paragraph 9) among the Holders of the Trust Securities.

3.       Liquidation Distribution Upon Dissolution.

                  In the event of any voluntary or involuntary dissolution,
winding-up or termination of the Trust (each a "Liquidation"), the then Holders
of the Trust Securities on the date of the Liquidation will be entitled to
receive out of the assets of the Trust available for distribution to Holders of
Trust Securities after satisfaction of liabilities of creditors, Distributions
in an amount equal to the aggregate of the stated liquidation amount of $25 per
Security plus accrued and unpaid Distributions thereon to


                                       I-5


<PAGE>   102



the date of payment (such amount being the "Liquidation Distribution"), unless,
in connection with such Liquidation, Convertible Debentures in an aggregate
principal amount equal to the aggregate stated liquidation amount of such Trust
Securities, with an interest rate equal to the Coupon Rate of, and bearing
accrued and unpaid interest in an amount equal to the accrued and unpaid
Distributions on, such Trust Securities, shall be distributed on a Pro Rata
basis to the Holders of the Trust Securities.

                  If, upon any such Liquidation, the Liquidation Distribution
can be paid only in part because the Trust has insufficient assets available to
pay in full the aggregate Liquidation Distribution, then the amounts payable
directly by the Trust on the Trust Securities shall be paid on a Pro Rata basis
in accordance with paragraph 9 below.

4.       Redemption and Distribution.

         (a)      Upon the repayment of the Convertible Debentures,
                  in whole or in part, whether at maturity or upon
                  redemption (either at the option of the Company or
                  pursuant to a Tax Event), the proceeds from such
                  repayment or payment shall be simultaneously
                  applied to redeem Trust Securities having an
                  aggregate liquidation amount equal to the
                  aggregate principal amount of the Convertible
                  Debentures so repaid or redeemed at a redemption
                  price equal to the redemption price of such repaid
                  or redeemed Convertible Debentures, together with
                  accrued and unpaid Distributions thereon through
                  the date fixed for redemption, payable in cash
                  (the "Redemption Price").

         (b)      If fewer than all the outstanding Trust Securities are to be
                  so redeemed, the Common Securities and the Preferred
                  Securities will be redeemed Pro Rata and the Preferred
                  Securities to be redeemed will be as described in paragraph
                  4(f)(ii) below.

         (c)      If, at any time, a Tax Event or an Investment
                  Company Event (each as defined below and each a
                  "Special Event") shall occur and be continuing,
                  the Administrative Trustees shall, unless the
                  Convertible Debentures are redeemed in the limited
                  circumstances in relation to a Tax Event described
                  in the following paragraph of this paragraph 4(c),
                  dissolve the Trust and, after satisfaction of
                  creditors of the Trust, if any, cause Convertible


                                       I-6


<PAGE>   103



                  Debentures held by the Property Trustee (w) having an
                  aggregate principal amount equal to the aggregate stated
                  liquidation amount of, (x) an interest rate identical to the
                  Coupon Rate of, (y) accrued and unpaid interest on, and (z)
                  the same record dates for payment as, the Trust Securities, to
                  be distributed to the Holders of the Trust Securities in
                  liquidation of such Holders' interest in the Trust on a Pro
                  Rata basis, within 90 days following the occurrence of such
                  Special Event (the "90 Day Period"); provided, however, that
                  in the case of a Tax Event, such dissolution and distribution
                  shall be conditioned on the Property Trustee's receipt of an
                  opinion of a nationally recognized independent tax counsel
                  experienced in such matters (a "No Recognition Opinion"),
                  which opinion may rely on published revenue rulings of the
                  Internal Revenue Service, to the effect that the Holders of
                  the Preferred Securities will not recognize any income, gain
                  or loss for United States federal income tax purposes as a
                  result of such dissolution and distribution of Convertible
                  Debentures, and provided, further, that if at the time there
                  is available to the Trust the opportunity to eliminate, within
                  the 90 Day Period, the Special Event by taking some
                  ministerial action, such as filing a form or making an
                  election, or pursuing some other similar reasonable measure
                  that in the sole judgment of the Company has, or will cause,
                  no adverse effect on the Trust, the Company or the Holders of
                  the Trust Securities and will involve no material cost
                  ("Ministerial Action"), the Trust will pursue such Ministerial
                  Action in lieu of dissolution.

                                    If in the event of a Tax Event, (i) after
                  receipt of a Tax Event Opinion (as defined below) by the
                  Trust, the Property Trustee has received an opinion (a
                  "Redemption Tax Opinion") of a nationally recognized
                  independent tax counsel experienced in such matters that, as a
                  result of a Tax Event, there is more than an insubstantial
                  risk that the Company would be precluded from deducting the
                  interest on the Convertible Debentures for United States
                  federal income tax purposes even if the Convertible Debentures
                  were distributed to the Holders of Trust Securities in
                  liquidation of such Holders' interest in the Trust as
                  described in this paragraph 4(c), or (ii) after


                                       I-7


<PAGE>   104



                  receipt of a Tax Event Opinion, the Administrative Trustees
                  shall have been informed by such tax counsel that a No
                  Recognition Opinion cannot be delivered to the Trust, the
                  Company shall have the right, upon not less than 30 nor more
                  than 60 days' notice, to redeem the Convertible Debentures in
                  whole (but not in part) for cash within 90 days following the
                  occurrence of such Tax Event, and promptly following such
                  redemption, the Trust Securities shall be redeemed at the
                  Redemption Price on a Pro Rata basis at $25 per Trust Security
                  plus accrued and unpaid distributions; provided, however, that
                  if at the time there is available to the Company or the Trust
                  the opportunity to eliminate, within such 90 Day Period, the
                  Tax Event by taking some Ministerial Action that has no
                  adverse effect on the Trust, the Holders of Trust Securities
                  or the Company, the Trust or the Company will pursue such
                  Ministerial Action in lieu of redemption.

                                    "Tax Event" means that the Property Trustee
                  shall have received an opinion of a nationally recognized
                  independent tax counsel experienced in such matters (a
                  "Dissolution Tax Opinion") to the effect that, as a result of
                  (a) any amendment to, or change (including any announced
                  prospective change) in, the laws (or any regulations
                  thereunder) of the United States or any political subdivision
                  or taxing authority thereof or therein, (b) any amendment to,
                  or change in, an interpretation or application of any such
                  laws or regulations by any legislative body, court,
                  governmental agency or regulatory authority (including the
                  enactment of any legislation and the publication of any
                  judicial decision or regulatory determination), (c) any
                  interpretation or pronouncement that provides for a position
                  with respect to such laws or regulations that differs from the
                  theretofore generally accepted position or (d) any action
                  taken by any governmental agency or regulatory authority,
                  which amendment or change is enacted, promulgated, issued or
                  announced or which interpretation or pronouncement is issued
                  or announced or which action is taken, in each case after the
                  date of the Offering Memorandum (collectively, a "Change in
                  Tax Law"), there is more than an insubstantial risk that (i)
                  the Trust is, or will be within 90 days of the date thereof,


                                       I-8


<PAGE>   105



                  subject to United States federal income tax with respect to
                  interest accrued or received on the Convertible Debentures,
                  (ii) the Trust is, or will be within 90 days of the date
                  thereof, subject to more than a de minimis amount of other
                  taxes, duties or other governmental charges, or (iii) interest
                  payable by the Company to the Trust on the Convertible
                  Debentures is not, or within 90 days of the date thereof will
                  not be, deductible by the Company for United States federal
                  income tax purposes. Notwithstanding anything in the previous
                  sentence to the contrary, a Tax Event shall not include any
                  Change in Tax Law that requires the Company for United States
                  federal income tax purposes to defer taking a deduction for
                  any original issue discount ("OID") that accrues with respect
                  to the Convertible Debentures until the interest payment
                  related to such OID is paid by the Company in money; provided,
                  that such Change in Tax Law does not create more than an
                  insubstantial risk that the Company will be prevented from
                  taking a deduction for OID accruing with respect to the
                  Convertible Debentures at a date that is no later than the
                  date the interest payment related to such OID is actually paid
                  by the Company in money.

                                    "Investment Company Event" means that the
                  Property Trustee shall have received an opinion of a
                  nationally recognized independent counsel experienced in
                  practice under the Investment Company Act (an "Investment
                  Company Event Opinion") that, as a result of a change in law
                  or regulation or a change in interpretation or application of
                  law or regulation by any legislative body, court, governmental
                  agency or regulatory authority (a "Change in 1940 Act Law"),
                  there is more than an insubstantial risk that the Trust is or
                  will be considered an Investment Company that is required to
                  be registered under the Investment Company Act, which Change
                  in 1940 Act Law becomes effective on or after the date of the
                  Offering Memorandum.

                                    On the date fixed for any distribution of
                  Convertible Debentures, upon dissolution of the Trust: (i) the
                  Trust Securities will no longer be deemed to be outstanding,
                  (ii) the Depositary or its nominee, as the record holder of
                  such Trust


                                       I-9


<PAGE>   106



                  Securities, will receive a registered global certificate or
                  certificates representing the Convertible Debentures to be
                  delivered upon such distribution and (iii) certificates
                  representing Trust Securities not held by Depositary or its
                  nominee will be deemed to represent beneficial interests in
                  Convertible Debentures having an aggregate principal amount
                  equal to the stated liquidation amount, and bearing accrued
                  and unpaid interest equal to accrued and unpaid Distributions,
                  on such Trust Securities until such certificates are presented
                  to the Company or its agent for transfer or reissuance.

         (d)      The Trust may not redeem fewer than all the outstanding Trust
                  Securities unless all accrued and unpaid Distributions have
                  been paid in cash on all Trust Securities for all quarterly
                  Distribution periods terminating on or before the date fixed
                  for redemption.

         (e)      If the Convertible Debentures are distributed to the Holders 
                  of the Trust Securities, pursuant to the terms of the
                  Indenture, the Company will use its best efforts to have the
                  Convertible Debentures listed on the New York Stock Exchange
                  or on such other exchange as the Preferred Trust Securities
                  were listed immediately prior to the distribution of the
                  Convertible Debentures.

         (f)      Redemption or Distribution Procedures.

                  (i)        Notice of any redemption of, or notice of
                             distribution of Convertible Debentures in
                             exchange for, the Trust Securities (a
                             "Redemption/Distribution Notice") will be
                             given by the Trust by mail to each Holder
                             of Trust Securities to be redeemed or
                             exchanged not fewer than 30 nor more than
                             60 days before the date fixed for
                             redemption or exchange thereof, which, in
                             the case of a redemption, will be the date
                             fixed for redemption of the Convertible
                             Debentures.  For purposes of the
                             calculation of the date of redemption or
                             exchange and the dates on which notices are
                             given pursuant to this paragraph 4(f)(i), a
                             Redemption/Distribution Notice shall be
                             deemed to be given on the day such notice

                  (ii)       In the event that fewer than all the outstanding
                             Trust Securities are to be redeemed, then the

                             Securities to be redeemed shall be allocated pro
                             rata among the Preferred Securities and the Common
                             Securities, it being understood that, in respect of

                  (iii)      If Trust Securities are to be redeemed and the
                             Trust gives a Redemption/Distribution Notice (which
                             notice is irrevocable), then, provided that the
                             Company has paid the Property Trustee a sufficient
                             amount of cash in connection with the related
                             redemption or maturity of the Convertible
                             Debentures, (A) with respect to Preferred
                             Securities held in book-entry form, by 12:00 noon,
                             New York City time, on the redemption date, the
                             Trust will deposit irrevocably with the Depositary
                             or its nominee (or successor Clearing Agency or its
                             nominee) funds sufficient to pay the applicable
                             Redemption Price with respect to such Preferred
                             Securities and will give the Depositary irrevocable
                             instructions and authority to pay the applicable
                             Redemption Price to the Holders of such Preferred
                             Securities represented by the Global Certificates,
                             and (B) with respect to Preferred Securities issued
                             in definitive form and Common Securities, the Trust
                             will irrevocably deposit with the Paying Agent
                             funds sufficient to pay the amount payable on
                             redemption to the Holders of such Trust Securities
                             upon surrender of their certificates. If a
                             Redemption/Distribution Notice shall have been
                             given and funds deposited as required, then on the
                             date of such deposit, all rights of Holders of such
                             Trust Securities so called for redemption will
                             cease, except (i) the right of the Holders of such
                             Trust Securities to receive the Redemption Price,
                             but without interest thereon, and (ii) the right to
                             convert such Trust Securities into Company Common
                             Stock in the manner described herein through the
                             close of business on the date fixed for redemption.
                             Neither the Administrative Trustees nor the Trust
                             shall be required to register or cause to be
                             registered the transfer of any Trust Securities
                             that have been so called for redemption. If any
                             date fixed for redemption of Trust Securities is
                             not a Business Day, then payment of the amount
                             payable on such date will be made on the next
                             succeeding day that is a Business

                             Day (without any interest or other payment in
                             respect of any such delay) except that, if such
                             Business Day falls in the next calendar year, such
                             payment will be made on the immediately preceding
                             Business Day, in each case with the same force and
                             effect as if made on such date fixed for
                             redemption. If payment of the Redemption Price in
                             respect of any Trust Securities is improperly
                             withheld or refused and not paid either by the
                             Trust or by the Company as guarantor pursuant to
                             the relevant Securities Guarantee, Distributions on
                             such Trust Securities will continue to accrue at
                             the then applicable rate, from the original
                             redemption date to the date of payment, in which
                             case the actual payment date will be considered the
                             date fixed for redemption for purposes of
                             calculating the amount payable upon redemption
                             (other than for purposes of calculating any
                             premium).

                  (iv)       In the event of any redemption in part, the Trust
                             shall not be required to (i) issue, register the
                             transfer of or exchange of any Preferred Security
                             during a period beginning at the opening of
                             business 15 days before any selection for
                             redemption of Preferred Securities and ending at
                             5:00 p.m. (New York City time) on the earliest date
                             in which the relevant notice of redemption is
                             deemed to have been given to all holders of
                             Preferred Securities to be so redeemed and (ii)
                             register the transfer of or exchange of any
                             Preferred Securities so selected for redemption, in
                             whole or in part, except for the unredeemed portion
                             of any Preferred Securities being redeemed in part.

                  (v)        Redemption/Distribution Notices shall be sent by
                             the Administrative Trustees on behalf of the Trust
                             to (A) in the case of Preferred Securities held in
                             book-entry form, the Depositary and, in the case of
                             Trust Securities held in definitive form, the
                             Holders of such certificates and (B) in respect of
                             the Common Securities, the Holder thereof.

                  (vi)       Subject to the foregoing and applicable law
                             (including, without limitation, United States
                             federal securities laws), the Company or any of its
                             subsidiaries may at any time and from time to time
                             purchase outstanding Preferred Securities by
                             tender, in the open market or by private agreement.

5.       Conversion Rights.

         The Holders of Trust Securities shall have the right at any time prior
         to 5:00 p.m. (New York City time) on the Business Day immediately
         preceding the date of repayment of such Trust Securities, whether at
         maturity or upon redemption (either at the option of the Company or
         pursuant to a Tax Event), at their option, to cause the Conversion
         Agent to convert Trust Securities, on behalf of the converting Holders,
         into shares of Company Common Stock of the Company in the manner
         described in, and subject to all of the terms and conditions of,
         Article Thirteen of the Trust Agreement.

6.       Voting Rights - Preferred Securities.

         (a)      Except as provided under paragraph 6(b) and paragraph 8, in
                  the Business Trust Act and as otherwise required by law and
                  the Trust Agreement, the Holders of the Preferred Securities
                  will have no voting rights. No vote or consent of the Holders
                  of the Preferred Securities will be required for the Trust to
                  redeem and cancel Preferred Securities or to distribute the
                  Convertible Debentures in accordance with the Trust Agreement
                  and the terms of the Trust Securities.

         (b)      Subject to the requirements set forth in this paragraph 6(b),
                  the Holders of a majority in liquidation amount of the
                  Preferred Securities, voting separately as a class, may direct
                  the time, method, and place of conducting any proceeding for
                  any remedy available to the Property Trustee and direct the
                  exercise of any trust or power conferred upon the Property
                  Trustee under the Trust Agreement, including the right to
                  direct the Property Trustee, as holder of the Convertible
                  Debentures, to (i) exercise the remedies available to it under
                  the Indenture as a holder of the Convertible Debentures, (ii)
                  waive any past


                                      I-14


<PAGE>   111



                  default and its consequences that are waivable under the
                  Indenture, (iii) exercise any right to rescind or annul a
                  declaration that the principal of all the Convertible
                  Debentures shall be due and payable, or (iv) consent to any
                  amendment, modification or termination of the Indenture or the
                  Convertible Debentures where such consent shall be required;
                  provided, however, that where a consent or action under the
                  Indenture would require the consent or act of the Holders of a
                  Super Majority of Convertible Debentures affected thereby, the
                  Property Trustee may only give such consent or take such
                  action at the written direction of the Holders of at least the
                  proportion in liquidation amount of the Preferred Securities
                  that the relevant Super Majority represents of the aggregate
                  principal amount of the Convertible Debentures outstanding.
                  The Property Trustee shall be under no obligation to revoke
                  any action previously authorized or approved by a vote of the
                  Holders of the Preferred Securities. Other than with respect
                  to directing the time, method and place of conducting any
                  remedy available to the Property Trustee or the Indenture
                  Trustee as set forth above, the Property Trustee shall be
                  under no obligation to take any action in accordance with the
                  directions of the Holders of the Preferred Securities under
                  this paragraph 6 unless the Property Trustee has obtained an
                  opinion of independent tax counsel to the effect that for the
                  purposes of United States federal income tax the Trust will
                  not be classified as other than a grantor trust on account of
                  such action and each Holder will be treated as owning an
                  undivided beneficial interest in the Convertible Debentures.
                  If the Property Trustee fails to enforce its rights under the
                  Convertible Debentures after a Holder of Preferred Securities
                  has made a written request, such Holder of Preferred
                  Securities may directly institute a legal proceeding against
                  the Company to enforce the Property Trustee's rights under the
                  Convertible Debentures without first instituting any legal
                  proceeding against the Property Trustee or any other Person.
                  Notwithstanding the foregoing, if an Event of Default has
                  occurred and is continuing and such event is attributable to
                  the failure of the Company to pay interest or principal on the
                  Convertible Debentures on the


                                      I-15

                  date such interest or principal is otherwise payable (or in
                  the case of redemption on the date fixed for redemption), then
                  a Holder of Preferred Securities may directly institute a
                  proceeding for enforcement of payment to such Holder (a
                  "Direct Action") of the principal of or interest on
                  Convertible Debentures having a principal amount equal to the
                  aggregate liquidation amount of the Preferred Securities of
                  such Holder on or after the respective due date specified in
                  the Convertible Debentures. Except as provided in the
                  preceding sentence, the Holders of Preferred Securities will
                  not be able to exercise directly any other remedy available to
                  the holders of the Convertible Debentures. In connection with
                  such Direct Action, the Company will be subrogated to the
                  rights of such Holder of Preferred Securities under the Trust
                  Agreement to the extent of any payment made by the Company to
                  such Holder of Preferred Securities in such Direct Action.

         (c)      Any required approval or direction of Holders of Preferred
                  Securities may be given at a separate meeting of Holders of
                  Preferred Securities convened for such purpose, at a meeting
                  of all of the Holders of Trust Securities in the Trust or
                  pursuant to written consent. The Property Trustee will cause a
                  notice of any meeting at which Holders of Preferred Securities
                  are entitled to vote, or of any matter upon which action by
                  written consent of such Holders is to be taken, to be mailed
                  to each Holder of record of Preferred Securities. Each such
                  notice will include a statement setting forth the following
                  information (i) the date of such meeting or the date by which
                  such action is to be taken, (ii) a description of any
                  resolution proposed for adoption at such meeting on which such
                  Holders are entitled to vote or of such matter upon which
                  written consent is sought and (iii) instructions for the
                  delivery of proxies or consents.

         (d)      Notwithstanding that Holders of Preferred Securities are
                  entitled to vote or consent under any of the circumstances
                  described above, any of the Preferred Securities that are
                  owned by the Company or any Affiliate of the Company shall not
                  be entitled to vote or consent and shall, for purposes of such
                  vote or consent, be treated as if


                                      I-16

                  such Preferred Securities were not outstanding.

7.       Voting Rights - Common Securities.

         (a)      Except as provided under paragraphs 7(b) and (c) and paragraph
                  8, in the Business Trust Act and as otherwise required by law
                  and the Trust Agreement, the Holders of the Common Securities
                  will have no voting rights. No vote or consent of the Holders
                  of the Common Securities will be required for the Trust to
                  redeem and cancel Common Securities or to distribute the
                  Convertible Debentures in accordance with the Trust Agreement
                  and the terms of the Trust Securities.

         (b)      The Holders of the Common Securities are entitled, in
                  accordance with Article V of the Trust Agreement, to vote to
                  appoint, remove or replace any Trustee or to increase or
                  decrease the number of Trustees.

         (c)      Subject to Section 2.6 of the Trust Agreement and only after
                  the Event of Default with respect to the Preferred Securities
                  has been cured, waived, or otherwise eliminated and subject to
                  the requirements of the penultimate sentence of this paragraph
                  7(c), the Holders of a majority in liquidation amount of the
                  Common Securities, voting separately as a class, may direct
                  the time, method, and place of conducting any proceeding for
                  any remedy available to the Property Trustee, or exercising
                  any trust or power conferred upon the Property Trustee under
                  the Trust Agreement, including (i) directing the time, method,
                  place of conducting any proceeding for any remedy available to
                  the Indenture Trustee, or exercising any trust or power
                  conferred on the Indenture Trustee with respect to the
                  Convertible Debentures, (ii) waive any past default and its
                  consequences that are waivable under Section 513 of the
                  Indenture, (iii) exercise any right to rescind or annul a
                  declaration that the principal of all the Convertible
                  Debentures shall be due and payable, or (iv) consent to any
                  amendment, modification or termination of the Indenture or the
                  Convertible Debentures where such consent shall be required;
                  provided that, where a consent or action under the --------
                  Indenture would require the consent or act of the Holders of a
                  Super Majority in principal amount of


                                      I-17


<PAGE>   114



                  Convertible Debentures affected thereby, the Property Trustee
                  may only give such consent or take such action at the written
                  direction of the Holders of at least the proportion in
                  liquidation amount of the Common Securities which the relevant
                  Super Majority represents of the aggregate principal amount of
                  the Convertible Debentures outstanding. Pursuant to this
                  paragraph 7(c), the Property Trustee shall not revoke any
                  action previously authorized or approved by a vote of the
                  Holders of the Preferred Securities. Other than with respect
                  to directing the time, method and place of conducting any
                  remedy available to the Property Trustee or the Indenture
                  Trustee as set forth above, the Property Trustee shall be
                  under no obligation to take any action in accordance with the
                  directions of the Holders of the Common Securities under this
                  paragraph 7(c) unless the Property Trustee has obtained an
                  opinion of independent tax counsel to the effect that for the
                  purposes of United States federal income tax the Trust will
                  not be classified as other than a grantor trust on account of
                  such action and each Holder will be treated as owning an
                  undivided beneficial interest in the Convertible Debentures.
                  If the Property Trustee fails to enforce its rights under the
                  Convertible Debentures after a Holder of Common Securities has
                  made a written request, such Holder of Common Securities may
                  institute a legal proceeding directly against the Company or
                  any other Person to enforce the Property Trustee's rights
                  under the Convertible Debentures, without first instituting
                  any legal proceeding against the Property Trustee or any other
                  Person.

         (d)      Any approval or direction of Holders of Common Securities may
                  be given at a separate meeting of Holders of Common Securities
                  convened for such purpose, at a meeting of all of the Holders
                  of Securities in the Trust or pursuant to written consent. The
                  Administrative Trustees will cause a notice of any meeting at
                  which Holders of Common Securities are entitled to vote, or of
                  any matter upon which action by written consent of such
                  Holders is to be taken, to be mailed to each Holder of record
                  of Common Securities. Each such notice will include a
                  statement setting forth (i) the date of such meeting or the
                  date by which such


                                      I-18


<PAGE>   115



                  action is to be taken, (ii) a description of any resolution
                  proposed for adoption at such meeting on which such Holders
                  are entitled to vote or of such matter upon which written
                  consent is sought and (iii) instructions for the delivery of
                  proxies or consents.

8.       Amendments to Trust Agreement and Indenture.

         (a)      In addition to any requirements under Section 11.1 of the
                  Trust Agreement, if any proposed amendment to the Trust
                  Agreement provides for, or the Administrative Trustees
                  otherwise propose to effect, (i) any action that would
                  adversely affect the powers, preferences or special rights of
                  the Trust Securities, whether by way of amendment to the Trust
                  Agreement or otherwise, or (ii) the dissolution, winding-up or
                  termination of the Trust, other than as described in Section
                  3.10 of the Trust Agreement, then the Holders of Trust
                  Securities as a class will be entitled to vote on such
                  amendment or proposal (but not on any other amendment or
                  proposal) and such amendment or proposal shall not be
                  effective except with the approval of the Holders of a Super
                  Majority in liquidation amount of the Trust Securities
                  affected thereby, voting together as a single class; provided,
                  however, if any amendment or proposal referred to in clause
                  (i) above would adversely affect only the Preferred Securities
                  or only the Common Securities, then only the affected class
                  will be entitled to vote on such amendment or proposal and
                  such amendment or proposal shall not be effective except with
                  the approval of a Super Majority in liquidation amount of such
                  class of Trust Securities.

         (b)      In the event the consent of the Property Trustee as the holder
                  of the Convertible Debentures is required under the Indenture
                  with respect to any amendment, modification or termination on
                  the Indenture or the Convertible Debentures, the Property
                  Trustee shall request the written direction of the Holders of
                  the Trust Securities with respect to such amendment,
                  modification or termination and shall vote with respect to
                  such amendment, modification or termination as directed by a
                  majority in liquidation amount of the Trust Securities voting
                  together as a single class;


                                      I-19


<PAGE>   116



                  provided, however, that where a consent under the Indenture
                  would require a Super Majority in aggregate principal amount
                  of the Convertible Debentures, the Property Trustee may only
                  give such consent at the written direction of the Holders of
                  at least the same proportion in aggregate stated liquidation
                  preference of the Trust Securities; provided, further, that
                  the Property Trustee shall not take any action in accordance
                  with the directions of the Holders of the Trust Securities
                  under this paragraph 8(b) unless the Property Trustee has
                  obtained an opinion of tax counsel to the effect that for the
                  purposes of United States federal income tax the Trust will
                  not be classified as other than a grantor trust on account of
                  such action.

9.       Pro Rata.

                  A reference in these terms of the Trust Securities to any
payment, distribution or treatment as being "Pro Rata" shall mean pro rata to
each Holder of Trust Securities according to the aggregate liquidation amount of
the Trust Securities held by the relevant Holder in relation to the aggregate
liquidation amount of all Trust Securities outstanding unless, in relation to a
payment, an Event of Default under the Trust Agreement has occurred and is
continuing, in which case any funds available to make such payment shall be paid
first to each Holder of the Preferred Securities pro rata according to the
aggregate liquidation amount of Preferred Securities held by the relevant Holder
relative to the aggregate liquidation amount of all Preferred Securities
outstanding, and only after satisfaction of all amounts owed to the Holders of
the Preferred Securities, to each Holder of Common Securities pro rata according
to the aggregate liquidation amount of Common Securities held by the relevant
Holder relative to the aggregate liquidation amount of all Common Securities
outstanding.

10.      Ranking.

                  The Preferred Securities rank pari passu and payment thereon
shall be made Pro Rata with the Common Securities, provided that, if on any
distribution date or redemption date an Event of Default occurs and is
continuing under the Indenture in respect of the Convertible Debentures held by
the Property Trustee, the rights of Holders of the Common Securities to payment
in respect of Distributions and


                                      I-20


<PAGE>   117



payments upon liquidation, redemption and otherwise are subordinated to the
rights to payment of the Holders of the Preferred Securities.

11.  Subordination

                  Payment of distributions on, and the amount payable upon
redemption of, the Trust Securi ties, as applicable, shall be made pro rata
based on the liquidation amount of the Trust Securities; provided, however,
that, if on any distribution date or redemption date an Event of Default shall
have occurred and be continuing, no payment of any distribution on, or amount
payable upon redemption of, any Common Security, and no other payment on account
of the redemption, liquidation or other acquisition of Common Securities, shall
be made unless payment in full in cash of all accumulated and unpaid
distributions on all outstanding Preferred Securities for all distribution
periods terminating on or prior thereto, or in the case of payment of the amount
payable upon redemption of the Preferred Securities, the full amount of such
amount in respect of all outstanding Preferred Securities shall have been made
or provided for, and all funds available to the Property Trustee shall first be
applied to the payment in full in cash of all distributions on, or the amount
payable upon redemption of, Preferred Securities then due and payable.

         In the case of any Event of Default, the holder of Common Securities
will be deemed to have waived any such Event of Default until all such Events of
Default with respect to the Preferred Securities have been cured, waived or
otherwise eliminated. Until any such Events of Default with respect to the
Preferred Securities have been so cured, waived or otherwise eliminated, the
Property Trustee shall act solely on behalf of the holders of the Preferred
Securities and not the holder of the Common Securities, and only the holders of
the Preferred Securities will have the right to direct the Property Trustee to
act on their behalf.

12.      Acceptance of Securities Guarantee and Indenture.

                  Each Holder of Preferred Securities and Common Securities, by
the acceptance thereof, agrees to the provisions of the Preferred Securities
Guarantee and the Common Securities Guarantee, respectively, including the
subordination provisions therein and to the provisions of the Indenture.


                                      I-21


<PAGE>   118



13.      No Preemptive Rights.

                  The Holders of the Trust Securities shall have no preemptive
rights to subscribe for any additional securities.

14.      Miscellaneous.

                  These terms constitute a part of the Trust Agreement.

                  The Company will provide a copy of the Trust Agreement, the
Preferred Securities Guarantee or the Common Securities Guarantee (as may be
appropriate), and the Indenture to a Holder without charge on written request to
the Company at its principal place of business.

                     5 1/4% Convertible Preferred Securities
           (liquidation amount $25 per Convertible Preferred Security)

                  Central Parking Finance Trust, a statutory business trust
formed under the laws of the State of Delaware (the "Trust"), hereby certifies
that ____________________________ (the "Holder") is the registered owner of
preferred securities of the Trust representing undivided beneficial interests in
the assets of the Trust designated the "5 1/4% Convertible Preferred Securities
(liquidation amount $25 per Convertible Preferred Security)" (the "Preferred
Securities"). The Preferred Securities are transferable on the books and records
of the Trust, in person or by a duly authorized attorney, upon surrender of this
certificate duly endorsed and in proper form for transfer. The designation,
rights, privileges, restrictions, preferences and other terms and provisions of
the Preferred Securities represented hereby are issued and shall in all respects
be subject to the provisions of the Amended and Restated Declaration of Trust of
the Trust dated as of March 18, 1998, as the same may be amended from time to

Securities set forth on the reverse hereof, which select provisions shall for
all purposes have the same effect as if set forth at this place.

                  By acceptance, the Holder agrees to treat, for United States
federal income tax purposes, the Convertible Debentures as indebtedness and the
Preferred Securities as evidence of indirect beneficial ownership in the
Convertible Debentures.

                  Unless the Property Trustee's Certificate of Authentication
hereon has been properly executed, these Preferred Securities shall not be

                              [REVERSE OF SECURITY]

                  Distributions payable on each Preferred Security will be fixed
at a rate per annum of 5 1/4% (the "Coupon Rate") of the stated liquidation
amount of $25 per Preferred Security, such rate being the rate of interest
payable on the Convertible Debentures to be held by the Property Trustee.
Distributions in arrears for more than one quarter will bear interest thereon
compounded quarterly at the Coupon Rate (to the extent permitted by applicable
law). The term "Distributions" as used herein includes any such interest
including any Additional Interest, Compounded Interest and Liquidated Damages,
if any, payable unless otherwise stated. A Distribution is payable only to the
extent that payments are made in respect of the Convertible Debentures held by
the Property Trustee and to the extent the Trust has funds available therefor.
The amount of Distributions payable for any period will be computed for any full
quarterly Distribution period on the basis of a 360-day year of twelve 30-day
months, and for any period shorter than a full quarterly Distribution period for
which Distributions are computed, Distributions will be computed on the basis of
the actual number of days elapsed per 90-day quarter.

                  Except as otherwise described below, Distributions on the
Preferred Securities will be cumulative, will accrue from the date of initial
issuance and will be payable quarterly in arrears, on the following dates, which
dates correspond to the interest payment dates on the Convertible Debentures:
January 1, April 1, July 1 and October 1 of each year, commencing on July 1,
1998, when, as and if available for payment by the Property Trustee. The Company
has the right at any time during the term of the Convertible Debentures to defer
interest payments from time to time by extending the interest payment period for
successive periods not exceeding 20 consecutive quarters (each an "Extension
Period") for each such period; provided, that no Extension Period may extend
beyond the maturity date of the Convertible Debentures. As a consequence of such
extension, quarterly Distributions on the Preferred Securities would be deferred
(though such Distributions would continue to accrue with interest since interest
would continue to accrue on the Convertible Debentures) during any such extended
interest payment period. In the event that the Company exercises this right,
then, during such period the Company has agreed, among other things, (a) not to
declare or pay dividends on, or make a distribution with respect to, or redeem
or


                                      A-1-6

purchase or acquire, or make a liquidation payment with respect to, any of its
capital stock (other than (i) purchases or acquisitions of shares of Company
Common Stock in connection with the satisfaction by the Company of its
obligations under any employee benefit plans or the satisfaction by the Company
of its obligations pursuant to any contract or security requiring the Company to
purchase shares of Company Common Stock, (ii) as a result of a reclassification
of the Company's capital stock or the exchange or conversion of one class or
series of the Company's capital stock for another class or series of the
Company's capital stock or (iii) the purchase of fractional interests in shares
of the Company's capital stock pursuant to the conversion or exchange provisions
of such capital stock or the security being converted or exchanged) or make any
guarantee payments with respect to the foregoing, (b) not to make any payment of
interest, principal or premium, if any, on or repay, repurchase or redeem any
debt securities (including guarantees) issued by the Company that rank pari
passu with or junior to the Convertible Debentures and (c) not to make any
guarantee payments with respect to the foregoing (other than pursuant to the
Preferred Securities Guarantee). Prior to the termination of any such Extension
Period, the Company may further extend the interest payment period; provided,
that such Extension Period, together with all such previous and further
extensions thereof, may not exceed 20 consecutive quarters or extend beyond the
maturity date of the Convertible Debentures. Upon the termination of any
Extension Period and the payment of all amounts then due, the Company may
commence a new Extension Period, subject to the above requirements.

                  Distributions on the Preferred Securities will be payable to
the Holders thereof as they appear on the books and records of the Trust on the
relevant record dates. The relevant record dates shall be the March 15, June 15,
September 15 and December 15 prior to the next such succeeding payment date,
except as otherwise described in the Trust Agreement.

                  The Preferred Securities shall be redeemable as provided in
the Trust Agreement.

                  The Preferred Securities shall be convertible into shares of
common stock of Central Parking Corporation ("Company Common Stock"), through
(i) the exchange of Preferred Securities for a portion of the Convertible
Debentures and (ii) the immediate conversion of such

                              [REVERSE OF SECURITY]

                  Distributions payable on each Common Security will be fixed at
a rate per annum of 5 1/4% (the "Coupon Rate") of the stated liquidation amount
of $25 per Common Security, such rate being the rate of interest payable on the
Convertible Debentures to be held by the Property Trustee. Distributions in
arrears for more than one quarter will bear interest thereon compounded
quarterly at the Coupon Rate (to the extent permitted by applicable law). The
term "Distributions" as used herein includes any such interest including any
Additional Interest, Compounded Interest and Liquidated Damages, if any, payable
unless otherwise stated. A Distribution is payable only to the extent that
payments are made in respect of the Convertible Debentures held by the Property
Trustee and to the extent the Trust has funds available therefor. The amount of
Distributions payable for any period will be computed for any full quarterly
Distribution period on the basis of a 360-day year of twelve 30-day months, and
for any period shorter than a full quarterly Distribution period for which
Distributions are computed, Distributions will be computed on the basis of the
actual number of days elapsed per 90-day quarter.

                  Except as otherwise described below, Distributions on the
Common Security Securities will be cumulative, will accrue from the date of
initial issuance and will be payable quarterly in arrears, on the following
dates, which dates correspond to the interest payment dates on the Convertible
Debentures: January 1, April 1, July 1 and October 1 of each year, commencing on
July 1, 1998, when, as and if available for payment by the Property Trustee. The
Company has the right at any time during the term of the Convertible Debentures
to defer interest payments from time to time by extending the interest payment
period for successive periods not exceeding 20 consecutive quarters (each an
"Extension Period") for each such period; provided, that no Extension Period may
extend beyond the maturity date of the Convertible Debentures. As a consequence
of such extension, quarterly Distributions on the Common Security Securities
would be deferred (though such Distributions would continue to accrue with
interest since interest would continue to accrue on the Convertible Debentures)
during any such extended interest payment period. In the event that the Company
exercises this right, then, during such period the Company has agreed, among
other things, (a) not to declare or pay dividends on, or make a distribution
with respect to, or redeem or purchase or acquire, or make a liquidation payment
with respect to, any of its capital stock (other than (i) purchases or
acquisitions of shares of Company Common Stock in connection with the
satisfaction by the Company of its obligations under any employee benefit plans
or the satisfaction by the Company of its obligations pursuant to any contract
or security requiring the Company to purchase shares of Company Common Stock,
(ii) as a result of a reclassification of the Company's capital stock or the


                                      A-2-3

exchange or conversion of one class or series of the Company's capital stock for
another class or series of the Company's capital stock or (iii) the purchase of
fractional interests in shares of the Company's capital stock pursuant to the
conversion or exchange provisions of such capital stock or the security being
converted or exchanged) or make any guarantee payments with respect to the
foregoing, (b) not to make any payment of interest, principal or premium, if
any, on or repay, repurchase or redeem any debt securities (including
guarantees) issued by the Company that rank pari passu with or junior to the
Convertible Debentures and (c) not to make any guarantee payments with respect
to the foregoing (other than pursuant to the Common Securities Guarantee). Prior
to the termination of any such Extension Period, the Company may further extend
the interest payment period; provided, that such Extension Period, together with
all such previous and further extensions thereof, may not exceed 20 consecutive
quarters or extend beyond the maturity date of the Convertible Debentures. Upon
the termination of any Extension Period and the payment of all amounts then due,
the Company may commence a new Extension Period, subject to the above
requirements.

                  The Common Securities shall be convertible into shares of
common stock of Central Parking Corporation ("Company Common Stock") through (i)
the exchange of Common Securities for a portion of the Convertible Debentures
and (ii) the immediate conversion of such Convertible Debentures into Company
Common Stock, in the manner and according to the terms set forth in Article
Thirteen of the Trust Agreement.

         buyer in the United States;

                  (D)      no directed selling efforts have been made in the
United States by or on behalf of the Owner or any affiliate
thereof;

                  (E)      if the Owner is a dealer in securities or has 
received a selling concession, fee or other remuneration in respect of the
Specified Securities, and the transfer is to occur during the Restricted Period,
then the requirements of Rule 904(c)(1) have been satisfied; and

                  (F)      the transaction is not part of a plan or scheme to 
evade the registration requirements of the Securities Act.

effected pursuant to Rule 144:

                  (A)       the transfer is occurring after a holding period of 
at least one year (computed in accordance with paragraph (d) of Rule 144) has
elapsed since the Specified Securities were last acquired from the Trust or from

Preferred Securities Guarantee to any Person except a Holder exercising his or

Guarantee, and use the same degree of care and skill in its exercise thereof, as
a prudent man would exercise or use under the circumstances in the conduct of
his own affairs.

    (d)           No provision of this Preferred Securities Guarantee shall be

            opinions expressed therein, upon any certificates or opinions
            furnished to the Preferred Guarantee Trustee and conforming to the
            requirements of this Preferred Securities Guarantee; but in the case

            examine the same to determine whether or not they conform on their
            face to the requirements of this Preferred Securities Guarantee;

      any action taken or omitted to be taken by it in good faith in accordance

      method and place of conducting any proceeding for any remedy available to
      the Preferred Guarantee Trustee, or exercising any trust or power
      conferred upon the Preferred Guarantee Trustee under this Preferred
      Securities Guarantee; and

      the Preferred Guarantee Trustee to expend or risk its own funds or
      otherwise incur personal financial liability in the performance of any of

      Preferred Guarantee Trustee shall have reasonable grounds for believing
      that the repayment of such funds or liability is not reasonably assured to
      it under the terms of this Preferred

                                       11

incurred by it in complying with such request or direction, including such
reasonable advances as may be requested by the Preferred Guarantee Trustee;

investigation into the facts or matters stated in any resolution, certificate,

impaired by reason of the happening from time to time of any of the following:

remedy conferred on the Holders pursuant to the terms of the Preferred
Securities, or any action on the part of the Trust granting indulgence or
extension of any kind;

    (d)           the voluntary or involuntary liquidation, dissolution, sale of
any collateral, receivership, insolvency, bankruptcy, assignment for the benefit
of creditors, reorganization, arrangement, composition or readjustment of debt

<PAGE>   22




otherwise constitute a legal or equitable discharge or defense of a guarantor,
it being the intent of this Section 5.4 that the obligations of the Guarantor
hereunder shall be absolute and unconditional under any and all circumstances.

         There shall be no obligation of the Holders or any other Persons to

exercise of any trust or power conferred upon the Preferred Guarantee Trustee
under this Preferred Securities Guarantee.

    (b)           Any Holder may directly institute a legal proceeding against 
the Guarantor to enforce the obligations of the Guarantor under this Preferred
Securities Guarantee without first instituting a legal proceeding against the

    (c)           If an event of default with respect to the Convertible 
Debentures constituting the failure to pay interest or principal on the
Convertible Debentures on the date such interest or principal is otherwise
payable has occurred and is continuing, then a Holder of Preferred Securities
may directly, at any time, institute a proceeding for enforcement of payment to
such Holder of the principal of or interest on the Convertible Debentures having
a principal amount equal to the aggregate liquidation amount of the Preferred
Securities of such Holder on or after the respective due date specified in the
Convertible Debentures. The Holders of Preferred Securities will not be able to
exercise directly any other remedy available to the holders of the Convertible
Debentures unless the Property Trustee (as defined in the Indenture) fails to do
so.

SECTION 5.6.               Guarantee of Payment.

         This Preferred Securities Guarantee creates a guarantee of payment and
not of collection.

of any such payment, any amounts are due and unpaid under this Preferred

                  2. Shelf Registration. (a) The Company and the Trust shall,
within 60 calendar days following the First Closing Date (as defined in the
Purchase Agreement), file with the Commission a Shelf Registration Statement
relating to the offer and sale of the Registrable Securities and, thereafter,
shall use their best efforts to cause such Shelf Registration Statement to be
declared effective under the Act as promptly as practicable and in no event
later than 150 calendar days after the First Closing Date; provided however,
that no Holder shall be entitled to be named as a selling securityholder in the
Shelf Registration Statement or to use the Prospectus forming a part thereof for
resales of Registrable Securities unless such Holder is an Electing Holder.

                  (b) The Company and the Trust shall each use its best efforts:

                  (i)  To keep the Shelf Registration Statement continuously
         effective (subject to any Suspension Period (as defined below)) in
         order to permit the Prospectus forming a part thereof to be usable by
         Electing Holders for resales of Registrable Securities for a period of
         two years after the latest date of original issuance of Preferred
         Securities, or such shorter period that will terminate upon the
         earliest of the following: (A) when all the Preferred Securities
         covered by the Shelf Registration Statement have been sold pursuant to
         the Shelf Registration Statement; (B) when all Convertible Debentures
         issued to Holders, in respect of Preferred Securities that had not been
         sold pursuant to the Shelf Registration Statement, have been sold
         pursuant to the Shelf Registration Statement; (C) when all shares of
         Company Common Stock issued upon conversion of any such Preferred
         Securities or any such Convertible Debentures that have not been sold
         pursuant to the Shelf Registration Statement have been sold pursuant to
         the Shelf Registration Statement; and (D) when, in the written opinion
         of counsel to the Trust and the Company, all outstanding Registrable
         Securities held by persons which are not Affiliates of the Trust or the
         Company may be resold immediately without registration or restriction,
         whether under the Act pursuant to Rule 144(k) or any successor
         provision thereto or otherwise (in any such case, such period being
         called the "Effectiveness Period").

                  (ii) At any time after the Effective Time of the Shelf
         Registration Statement, at the earlier of (i) 30 days after the request
         by any Holder that is not then an Electing Holder identified as a
         selling securityholder in the Prospectus at the Effective Time or (ii)
         the receipt by the Company of Notices and Questionnaires by Holders
         representing 5% or greater of the outstanding Registrable Securities,
         to take any action reasonably necessary to enable such Holder to use
         the Prospectus forming a part thereof for resales of Registrable
         Securities, including, without limitation, any action necessary to
         identify such Holder as a selling securityholder in the Shelf
         Registration Statement and any action required pursuant to Section 3
         (j) hereof; provided, however, that nothing in this subparagraph shall
         relieve such Holder of the obligation to return a completed and signed
         Notice and Questionnaire to the Company or the Trust in accordance with
         Section 3(a)(2) hereof and to provide to the Trust and the Company, in
         writing, any information with


                                        4

<PAGE>   5



         respect to such Holder or the Registrable Securities held by such
         Holder as is, in the reasonable opinion of counsel to the Trust or the
         Company, required under applicable law to enable such Holder to use
         such Prospectus for resales of such Registrable Securities; and

                  (iii) If at any time prior to the end of the Effectiveness
         Period, the Preferred Securities are convertible into securities other
         than Company Common Stock, to cause such securities to be included in
         the Shelf Registration Statement no later than the date on which the
         Preferred Securities may first be converted into such securities.

                  (c) If (i) on or prior to the date 60 days after the First
Closing Date a Shelf Registration Statement has not been filed with the
Commission or (ii) on or prior to the date 150 days after the First Closing Date
such Shelf Registration Statement has not been declared effective or (iii) on or
after the date 60 days following the receipt by the Company of such Notices and
Questionnaires required pursuant to Section 2(b)(ii) hereof, an amendment to the
Shelf Registration Statement has not been filed pursuant to Section 3(j) hereof
(each such event, a "Registration Default"), additional interest ("Liquidated
Damages") will accrue on the Convertible Debentures, and, accordingly,
additional distributions will accrue on the Preferred Securities, from and
including the day following such Registration Default until the earlier of such
date as the Shelf Registration Statement is filed or declared effective, as the
case may be, or the end of the Effectiveness Period. Liquidated Damages will be
paid quarterly in arrears (subject to the Company's right to defer the payment
of Liquidated Damages during any Extension Period (as defined in the
Indenture)), with the first quarterly payment due on the first interest or
distribution payment date, as applicable, following the date on which such
Liquidated Damages begin to accrue, and will accrue at a rate per annum equal to
an additional one-quarter of one percent (0.25%) of the principal amount or
liquidation amount, as applicable, to and including the 60th day following such
Registration Default and one-half of one percent (0.50%) thereof from and after
the 61st day following such Registration Default. In the event that the Shelf
Registration Statement ceases to be effective during the Effectiveness Period
for more than 90 consecutive days or any 120 days, whether or not consecutive,
which time period includes any Suspension Period (as defined below), during any
12-month period, then the interest rate borne by the Convertible Debentures and
the distribution rate borne by the Preferred Securities will each increase by an
additional one-half of one percent (0.50%) per annum from the 91st or 121st day,
as the case may be, of the applicable 12-month period such Shelf Registration
Statement ceases to be effective until such time as the earlier to occur of the
Shelf Registration Statement again becoming effective and the end of the
Effectiveness Period.

                  (d) The Company and the Trust shall each be deemed not to have
used its best efforts to keep the Shelf Registration Statement effective during
the Effectiveness Period if either the Trust or the Company voluntarily takes
any action that would result in Electing Holders not being able to offer and
sell any of their Registrable Securities during such period, unless (i) such
action is required by applicable law, (ii) upon the occurrence of any event
contemplated by paragraph 3(d)(2)(iii) below, and such action is taken by the
Trust or the Company in good faith and for valid business reasons or (iii) the
continued effectiveness of the Shelf Registration Statement would require the
Trust or the Company to disclose a material financing, acquisition or other
corporate development, and the proper officers of the Company shall have
determined in good faith that such disclosure is not in the best interest of the
Company and its stockholders and, in the case of clause (ii) above, the Company
and the Trust thereafter promptly comply with the requirements of paragraph 3(j)
below. Any such period during which the Company and the Trust are permitted to
suspend the effectiveness of the Shelf Registration Statement is referred to
herein as the "Suspension Period."

                  3. Registration Procedures. In connection with the Shelf
Registration Statement, the following provisions shall apply:

                           (a) (1) The Company shall not be required to take any
                  action to name such Holder as a selling securityholder in the
                  Shelf Registration Statement or to enable such Holder to use
                  the Prospectus forming a part thereof for resales of
                  Registrable Securities until such Holder has returned a
                  completed and signed Notice and Questionnaire to the Company
                  and the Trust and provided to the Trust and the Company such
                  information with respect to such Holder or the Registrable
                  Securities held by such Holder as is, in the reasonable
                  opinion of counsel to the Trust or the Company, required to
                  enable such Holder to use the Prospectus for resales of
                  Registrable Securities.

                           (2) Not less than 40 calendar days prior to the
                  Effective Time of the Shelf Registration Statement, the
                  Company or the Trust shall mail the Notice and Questionnaire
                  to each Holder. No Holder shall be entitled to be named as a
                  selling securityholder in the Shelf Registration Statement as
                  of the Effective Time, and no Holder shall be entitled to use
                  the Prospectus forming a part thereof for resales of
                  Registrable Securities at any time, unless such Holder has
                  returned a completed and signed Notice and Questionnaire to
                  the Company and the Trust and provided to the Trust and the
                  Company such information with respect to such Holder of the
                  Registrable Securities held by such Holder as is, in the
                  reasonable opinion of counsel to the Trust or the Company,
                  required to enable such Holder to use the Prospectus for
                  resales of Registrable Securities; provided, however, that
                  only Holders who have completed and returned the Notice and
                  Questionnaire and any such additional information requested of
                  such Holder to the Company or the Trust on or before the day
                  that is ten days prior to the Effective Time shall be entitled
                  to be named as a selling securityholder in the Shelf
                  Registration Statement as of the Effective Time.

                           (3) The term "Electing Holder" shall mean any Holder
                  that has returned a completed and signed Notice and
                  Questionnaire to the Company in accordance with Section
                  3(a)(1) or 3(a)(2) hereof and provided to the Trust and the
                  Company such information with respect to such Holder or the
                  Registrable Securities held by such Holder as is, in the
                  reasonable opinion of counsel to the Trust or the Company,
                  required to enable such Holder to use the Prospectus for
                  resales of Registrable Securities.

                  (b) The Company and the Trust shall furnish to each Electing
Holder, prior to the Effective Time, a copy of the Shelf Registration Statement
initially filed with the Commission, and shall furnish to such Holders copies of
each amendment thereto and each amendment or supplement, if any, to the
Prospectus included therein, and shall consider in good faith for inclusion in
each such document, at the Effective Time such comments as such Holders or their
counsel reasonably may propose.

                  (c) The Company and the Trust shall promptly take such action
as may be necessary so that (i) each of the Shelf Registration Statement and any
amendment thereto and the Prospectus forming part thereof and any amendment or
supplement thereto (and each report or other document incorporated therein by
reference in each case) complies in all material respects with the Securities
Act and the Rules and Regulations, (ii) each of the Shelf Registration Statement
and any amendment thereto does not, when it becomes effective, contain an 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 and
(iii) each of the Prospectus forming part of the Shelf Registration Statement,
and any amendment or supplement to such Prospectus, does not at any time during
the Effectiveness Period include an untrue statement of a material


                                        6

<PAGE>   7



fact or omit to state a material fact necessary in order to make the statements
therein, in the light of the circumstances under which they were made, not
misleading.

                  (d) (1) The Company shall promptly advise the Initial
Purchasers and, in the case of clause (i), the Electing Holders and, if
requested by the Initial Purchasers or any such Electing Holder, confirm such
advice in writing:

                           (i)  when the Shelf Registration Statement and any
         amendment thereto has been filed with the Commission and when the Shelf
         Registration Statement or any post effective amendment thereto has
         become effective; and

                           (ii) of any request by the Commission for amendments
         or supplements to the Shelf Registration Statement or the Prospectus
         included therein or for additional information.

                           (2) The Company shall promptly advise each Electing
         Holder of:

                           (i)   the issuance by the Commission of any stop
         order suspending the effectiveness of the Shelf Registration Statement
         or the initiation of any proceedings for such purpose;

                           (ii)  the receipt by the Company or the Trust of any
         notification with respect to the suspension of the qualification of the
         securities included in the Shelf Registration Statement for sale in any
         jurisdiction or the initiation of any proceeding for such purpose; and

                           (iii) the happening of any event that requires the
         making of any changes in the Shelf Registration Statement or the
         Prospectus included therein so that, as of such date, such Shelf
         Registration Statement and Prospectus do not contain an untrue
         statement of a material fact and do not omit to state a material fact
         required to be stated therein or necessary to make the statements
         therein (in the case of the Prospectus, in light of the circumstances
         under which they were made) not misleading (which advice shall be
         accompanied by an instruction to suspend the use of the Prospectus
         until the requisite changes have been made).

                  (e) The Company and the Trust shall each use its best efforts
to prevent the issuance, and if issued to obtain the withdrawal, of any stop
order suspending the effectiveness of the Shelf Registration Statement at the
earliest possible time.

                  (f) The Company and the Trust shall furnish to each Electing
Holder, without charge, at least one copy of the Shelf Registration Statement
and all post-effective amendments thereto, including financial statements and
schedules, and, if such Holder so requests in writing, all reports, other
documents and exhibits that are filed with or incorporated by reference in the
Shelf Registration Statement.

                  (g) The Company and the Trust shall, during the Effectiveness
Period, deliver to each Electing Holder, without charge, as many copies of the
Prospectus (including each preliminary Prospectus) included in the Shelf
Registration Statement and any amendment or supplement thereto as such Electing
Holder may reasonably request; and the Company and the Trust each consents
(except during the continuance of any event described in Section 3(d)(2)(iii)
above or during any Suspension Period) to the use of the Prospectus and any
amendment or supplement thereto by each of the Electing Holders in connection
with the offering and sale of the Registrable Securities covered by the
Prospectus and any amendment or supplement thereto during the Effectiveness
Period.



                                        7

<PAGE>   8



                  (h) Prior to any offering of Registrable Securities pursuant
to the Shelf Registration Statement, the Company and the Trust shall (1)
register or qualify or cooperate with the Electing Holders and their respective
counsel in connection with the registration or qualification of such Registrable
Securities for offer and sale under the securities or "blue sky" laws of such
jurisdictions within the United States as any Electing Holder may reasonably
request, (2) keep such registrations or qualifications in effect (subject to any
Suspension Period) and comply with such laws so as to permit the continuance of
offers and sales in such jurisdictions for so long as may be necessary to enable
any Electing Holder or underwriter, if any, to complete its distribution of
Registrable Securities pursuant to the Shelf Registration Statement, and (3)
take any and all other actions necessary or advisable to enable the disposition
in such jurisdictions of such Registrable Securities; provided, however, that in
no event shall the Company or the Trust be obligated to (i) qualify generally to
do business or as a foreign corporation or as a dealer in securities in any
jurisdiction where each would not otherwise be required to so qualify but for
this Section 3(h), (ii) file any general consent to service of process in any
jurisdiction where it is not as of the date hereof so subject or (iii) subject
itself to taxation in any jurisdiction where it is not otherwise so subject.

                  (i) Unless any Registrable Securities shall be in book-entry
only form, the Company and the Trust shall cooperate with the Electing Holders
to facilitate the timely preparation and delivery of certificates representing
Registrable Securities to be sold pursuant to the Shelf Registration Statement
free of any restrictive legends and in such permitted denominations and
registered in such names as Electing Holders may request in connection with the
sale of Registrable Securities pursuant to the Shelf Registration Statement.

                  (j) Upon the occurrence of any event contemplated by
paragraphs 2(b)(ii) and 3(d)(2)(iii) above, the Company and the Trust shall
promptly prepare a post-effective amendment or supplement to the Shelf
Registration Statement or the Prospectus, or any document incorporated therein
by reference, or file any other required document so that, as thereafter
delivered to Initial Purchasers of the Registrable Securities included therein,
the Prospectus will not include an untrue statement of a material fact or omit
to state any material fact necessary to make the statements therein, in the
light of the circumstances under which they were made, not misleading (except,
in each case, for an untrue statement of a material fact or omission of a
material fact made in reliance on and in conformity with written information
furnished to the Trust or the Company by or on behalf of any Electing Holders);
provided, however, if the proper officers of the Company determine in good faith
that disclosure in the Shelf Registration Statement of a material financing,
acquisition or other corporate transaction would not be in the best interests of
the Company and its stockholders, the Company and the Trust shall not be
required to prepare and file such amendment, supplement or document for such
period as such officers shall have determined in good faith is in the best
interests of the Company. Upon receipt of written notice from the Company or the
Trust of the occurrence of any event contemplated by paragraph 3(d)(2)(iii)
above or of any Suspension Period, each Holder shall forthwith discontinue
disposition of Registrable Securities until such Holder has received copies of
the supplemental or amended Prospectus required by this paragraph 3(j), or until
such Holder is advised by the Company or the Trust that the use of the
Prospectus may be resumed and, if so directed by the Company, such Holder shall
deliver to the Company (at the Company's expense) all copies then in such
Holder's possession of the Prospectus covering such Registrable Securities
current at the time of such notice.

                  (k) Not later than the effective date of any Shelf
Registration Statement hereunder, the Company and the Trust shall each provide a
CUSIP number for the Preferred Securities registered under such Shelf
Registration Statement; in the event of and at the time of any distribution of
the Convertible Debentures to Holders, the Company and the Trust shall provide a
CUSIP number for the Convertible


                                        8

<PAGE>   9



Debentures and provide the applicable trustee with certificates for such
Registrable Securities, in a form eligible for deposit with DTC.

                  (l) The Company and the Trust shall each use its best efforts
to comply with all applicable Rules and Regulations, and to make generally
available to its securityholders as soon as practicable after (i) the effective
date (as defined in Rule 158(c) under the Securities Act) of the Shelf
Registration Statement, (ii) the effective date of each post- effective
amendment to the Shelf Registration Statement, and (iii) the date of each filing
by the Company with the Commission of an Annual Report on Form 10-K that is
incorporated by reference in the Shelf Registration Statement, an earnings
statement of the Company and its subsidiaries complying with Section 11(a) of
the Securities Act and the rules and regulations of the Commission thereunder
(including, at the option of the Company, Rule 158).

                  (m) The Company and the Trust shall each use its best efforts
to cause the Indenture, the Trust Agreement and the Guarantee to be qualified
under the Trust Indenture Act in a timely manner.

                  (n) In the event of an underwritten offering conducted
pursuant to Section 6 hereof, the Company and the Trust shall, if requested,
promptly include or incorporate in a Prospectus supplement or post-effective
amendment to the Shelf Registration Statement such information as the Managing
Underwriters reasonably agree should be included therein and to which the
Company does not reasonably object and shall make all required filings of such
Prospectus supplement or post-effective amendment as soon as practicable after
it is notified of the matters to be included or incorporated in such Prospectus
supplement or post-effective amendment.

                  (o) The Company and the Trust shall enter into such customary
agreements (including an underwriting agreement in customary form in the event
of an underwritten offering conducted pursuant to Section 6 hereof) and take all
other appropriate actions in order to expedite and facilitate the registration
and disposition of the Registrable Securities, and in connection therewith, if
an underwriting agreement is entered into, cause the same to contain
indemnification provisions and procedures reasonably similar to those set forth
in Section 5 hereof with respect to all parties to be indemnified pursuant to
Section 5 hereof.

                  (p)  The Company and the Trust shall:

                           (i) (A) make available for inspection by Electing
         Holders, any underwriter participating in any disposition pursuant to
         such Shelf Registration Statement, and any attorney, accountant or
         other agent retained by such holders or any such underwriter all
         relevant financial and other records, pertinent corporate or other
         documents and properties of the Company, its subsidiaries and the
         Trust, and (B) cause the officers, directors, employees, trustees and
         agents of the Company and the Trust to supply all information requested
         by such Holders or any such underwriter, attorney, accountant or agent
         in connection with the Shelf Registration Statement, in each case, as
         is customary for similar due diligence examinations; provided, however,
         that each Electing Holder and its representatives and agents shall
         execute an agreement (in form reasonably acceptable to the Company)
         providing that all records, information and documents that are
         designated in writing by the Company and the Trust, in good faith, as
         confidential shall not be used for any other purpose and shall be kept
         confidential by such Holders and any such underwriter, attorney,
         accountant or agent, unless such disclosure is made in connection with
         a court proceeding or required by law, or such records, information or
         documents become available to the public generally or through a third
         party without an accompanying obligation of confidentiality; and
         provided further that, if the foregoing inspection and information
         gathering would, in the Company's reasonable judgment, disrupt the
         Company's conduct of its business, such inspection


                                        9

<PAGE>   10



         and information gathering shall be coordinated on behalf of the
         Electing Holders and the other parties entitled thereto by one counsel
         designated by and on behalf of Electing Holders and other parties (the
         fees and expenses of such counsel to be borne by such Electing Holders
         except to the extent set forth in Section 4);

                           (ii)  in connection with any underwritten offering
         conducted pursuant to Section 6 hereof, make such representations and
         warranties to the Holders participating in such underwritten offering
         and to the Managing Underwriters, in form, substance and scope as are
         customarily made by the Company and the Trust to underwriters in
         primary underwritten offerings of equity and convertible preferred and
         debt securities and covering matters including, but not limited to,
         those set forth in the Purchase Agreement;

                           (iii) in connection with any underwritten offering
         conducted pursuant to Section 6 hereof, obtain opinions of counsel
         (which counsel may be an employee of the Company) to the Company and
         the Trust (which counsel and opinions (in form, scope and substance)
         shall be reasonably satisfactory to the Managing Underwriters)
         addressed to each Holder participating in such underwritten offering
         and the underwriters, covering such matters as are customarily covered
         in opinions requested in underwritten offerings and such other matters
         as may be reasonably requested by such Holders and underwriters (it
         being agreed that the matters to be covered by such opinions shall
         include, without limitation, as of the date of the opinion and as of
         the Effective Time of the Shelf Registration Statement or most recent
         post-effective amendment thereto, as the case may be, a customary
         opinion on the absence from the Shelf Registration Statement and the
         Prospectus, including the documents incorporated by reference therein,
         of an untrue statement of a material fact or the omission of a material
         fact required to be stated therein or necessary to make the statements
         therein not misleading;

                           (iv)  in connection with any underwritten offering
         conducted pursuant to Section 6 hereof, obtain "cold comfort" letters
         and updates thereof from the independent public accountants of the
         Company and the Trust, addressed to each Holder participating in such
         underwritten offering (if such Holder has provided such letter,
         representations or documentation, if any, required for such "cold
         comfort" letter to be so addressed) and the underwriters, in customary
         form and covering matters of the type customarily covered in "cold
         comfort" letters in connection with primary underwritten offerings;

                           (v)   in connection with any underwritten offering
         conducted pursuant to Section 6 hereof, deliver such documents and
         certificates as may be reasonably requested by any Holders
         participating in such underwritten offering and the Managing
         Underwriters, if any, including, without limitation, certificates to
         evidence compliance with Section 3(j) hereof and with any conditions
         contained in the underwriting agreement or other agreements entered
         into by the Company and the Trust.

                  (q) The Company and the Trust will each use its best efforts
to cause the Company Common Stock issuable upon conversion of the Preferred
Securities to be listed for quotation on the New York Stock Exchange or other
stock exchange or trading system on which the Company Common Stock primarily
trades on or prior to the Effective Time of the Shelf Registration Statement
hereunder.

                  (r) The Company and the Trust shall each use reasonable best
efforts to take all other steps necessary to effect the registration, offering
and sale of the Registrable Securities covered by the Shelf Registration
Statement contemplated hereby.


                                       10

<PAGE>   11




                  (s) Upon receipt of written notice from the Company that a
Suspension Period is in effect, each Holder shall forthwith discontinue
disposition of Registrable Securities until such Holder has received copies of
the supplemental or amended Prospectus required by Section 3(j) hereof, or until
such Holder is advised in writing by the Company that the use of the Prospectus
may be resumed, and, if so directed by the Company, such Holder shall deliver to
the Company (at the Company's expense) all copies then in such Holder's
possession, other than permanent file copies, of the Prospectus covering such
Registrable Securities current at the time of receipt of such notice.

                  4. Registration Expenses. The Company and the Trust shall each
bear all fees and expenses customarily borne by issuers in a underwritten
secondary offering by selling securityholders or in an underwritten offering, as
the case may be, incurred in connection with the performance of its obligations
under Sections 2, 3 and 6 hereof. In addition, in the event of an underwritten
offering of Registrable Securities conducted pursuant to Section 6 hereof, or if
in any other event the Company requires that inspection and information
gathering be coordinated by counsel for the Electing Holders as provided in
Section 3(p)(i) hereof, the Company shall pay the fees and expenses of a single
counsel selected by the Electing Holders of not less than 25% of the Registrable
Securities to be included in such underwritten offering (or, in any such other
event, included in the Shelf Registration Statement) to represent them.

                  5.  Indemnification and Contribution.

                  (a) Indemnification by the Company. Upon the registration of
the Registrable Securities pursuant to Section 2 hereof, and in consideration of
the agreements of the Electing Holders and any underwriters, selling agents or
other securities professionals contained in Section 5(b) hereof, the Company and
the Trust, jointly and severally, agree to indemnify and hold harmless each
Electing Holder and each underwriter, selling agent or other securities
professional, if any, which facilitates the disposition of Registrable
Securities, and each of their respective officers and directors and each person
who controls such Electing Holder, underwriter, selling agent or other
securities professional within the meaning of Section 15 of the Securities Act
or Section 20 of the Exchange Act (each such person being sometimes referred to
as an "Indemnified Person") against any losses, claims, damages or liabilities,
joint or several, to which such Indemnified Person may become subject under the
Securities Act or otherwise, insofar as such losses, claims, damages or
liabilities (or actions in respect thereof) arise out of or are based in whole
or in part upon any untrue statement or alleged untrue statement of any material
fact contained in any Shelf Registration Statement under which such Registrable
Securities are to be registered under the Securities Act, or any Prospectus
contained therein or any amendment or supplement thereto, or arise out of or are
based upon the omission or alleged omission to state therein a material fact
required to be stated therein or necessary to make the statements therein not
misleading, and will reimburse such Indemnified Person for any legal or other
expenses reasonably incurred by them in connection with investigating or
defending any such loss, claim, damage, liability or action as such expenses are
incurred; provided, however, that the Company and the Trust will not be liable
in any such case to the extent that any such loss, claim, damage or liability
arises out of or is based upon any untrue statement or alleged untrue statement
or omission or alleged omission made in such Shelf Registration Statement or
Prospectus, or amendment or supplement, in reliance upon and in conformity with
written information furnished to the Company or the Trust by such Indemnified
Person expressly for use therein.

                  The foregoing notwithstanding, the Trust and the Company shall
not be liable to the extent that such losses, claims, damages or liabilities
arise out of or are based upon an untrue statement or alleged untrue statement
or omission or alleged omission made in any Prospectus that is a preliminary
prospectus


                                       11

<PAGE>   12



if such Indemnified Person failed to send or deliver a copy of the Prospectus
(in the form it was first provided to such parties for confirmation of sales or
as amended or supplemented prior to such confirma tion of sales) to the Electing
Holders asserting such losses, claims, damages or liabilities on or prior to the
delivery of written confirmation of any sale of securities covered thereby to
such Electing Holder in any case where such delivery is required by the
Securities Act and a court of competent jurisdiction in a judgment not subject
to appeal or final review shall have determined that such Prospectus would have
corrected such untrue statement or omission.

                  In addition, the Trust and the Company shall not be liable to
the extent that any such losses, claims, damages or liabilities arise out of or
are based upon an untrue statement or alleged untrue statement or omission or
alleged omission in a Prospectus (x) if such untrue statement or omission or
alleged untrue statement or omission is corrected in an amendment or supplement
to such Prospectus and (y) having previously been furnished by or on behalf of
the Trust or the Company with copies of the Prospectus as amended or
supplemented, such Indemnified Person thereafter fails to deliver such
Prospectus as so amended or supplemented prior to or concurrently with the sale
to the person who purchased a Registrable Security from such Indemnified Person
and who is asserting such losses, claims, damages or liabilities.

                  (b) Indemnification by the Holders and any Agents and
Underwriters. Each Electing Holder agrees, as a consequence of the inclusion of
any of such Holder's Registrable Securities in such Shelf Registration
Statement, and each underwriter, selling agent or other securities professional,
if any, which facilitates the disposition of Registrable Securities shall agree,
as a consequence of facilitating such disposition of Registrable Securities,
severally and not jointly, to (i) indemnify and hold harmless each of the
Company and the Trust, its directors, trustees, agents and officers who sign any
Shelf Registration Statement and each person, if any, who controls the Company
or the Trust within the meaning of either Section 15 of the Securities Act or
Section 20 of the Exchange Act (collectively referred to as the "Indemnified
Party"), against any losses, claims, damages or liabilities to which the Company
or the Trust or such other persons may become subject, under the Securities Act
or otherwise, insofar as such losses, claims, damages or liabilities (or actions
in respect thereof) arise out of or are based upon any untrue statement or
alleged untrue statement of any material fact contained in such Shelf
Registration Statement or Prospectus, or any amendment or supplement, or arise
out of or are based upon the omission or alleged omission to state therein a
material fact required to be stated therein or necessary to make the statements
therein not misleading, in each case to the extent, but only to the extent, that
such untrue statement or alleged untrue statement or omission or alleged
omission was made in reliance upon and in conformity with written information
furnished to the Company or the Trust by such Electing Holder, underwriter,
selling agent or other securities professional expressly for use therein, and
(ii) reimburse the Company and the Trust for any legal or other expenses
reasonably incurred by the Company and the Trust in connection with
investigating or defending any such loss, claim, damage, liability or action as
such expenses are incurred.

                  (c) Notices of Claims, Etc. If any action or proceeding
(including any governmental investigation or inquiry) shall be brought or
asserted against an Indemnified Person under subsection (a) or an Indemnified
Party under subsection (b) (collectively referred to as the "Indemnified
Holder") in respect of which indemnity may be sought, such Indemnified Holder
shall promptly notify the person against whom such indemnity may be sought (an
"Indemnifying Party") in writing, and the Indemnifying Party shall assume the
defense thereof, including the employment of counsel reasonably satisfactory to
such Indemnified Holder and the payment of all expenses in connection therewith;
but the omission so to notify the Indemnifying Party shall not relieve it from
any liability which it may have to any Indemnified Holder otherwise than under
this Section 5. Such Indemnified Holder shall have the right to employ separate
counsel in any such action and to participate in the defense thereof, but the
fees and expenses of such separate counsel shall be the expense of such
Indemnified Holder unless (i) the Indemnifying Party has


                                       12

<PAGE>   13



agreed to pay such fees and expenses, (ii) the Indemnifying Party shall have
failed to promptly assume the defense of such action or proceeding or has failed
to employ counsel reasonably satisfactory to such Indemnified Holder in any such
action or proceeding or (iii) the named parties to any such action or proceeding
(including any impended parties) include both such Indemnified Holder and the
Indemnifying Party, and such Indemnified Holder shall have been advised by
counsel that there may be one or more legal defenses available to such
Indemnified Holder that are different from or additional to those available to
the Indemnifying Party or that a conflict may exist between the Indemnified
Holder and the Indemnifying Party. If such Indemnified Holder notifies the
Indemnifying Party in writing that it elects to employ separate counsel at the
expense of the Indemnifying Party as permitted by the provisions of the
preceding sentence, the Indemnifying Party shall not have the right to assume
the defense of such action or proceeding on behalf of such Indemnified Holder.
The foregoing notwithstanding, the Indemnifying Party shall not be liable for
the fees and expenses of more than one legal counsel (in addition to any local
counsel) at any time for such Indemnified Holder and any other Indemnified
Holders (which firm shall be designated in writing by such Indemnified Holders)
in connection with any one such action or proceeding or separate but
substantially similar or related actions or proceedings in the same jurisdiction
arising out of the same general allegations or circumstances. The Indemnifying
Party shall not be liable for any settlement of any such action or proceeding
effected without the Indemnifying Party's prior written consent, and the
Indemnifying Party agrees to indemnify and hold harmless any Indemnified Holder
from and against any loss, damage, liability or expense by reason of any
settlement of any action effected with the written consent of the Indemnifying
Party. No Indemnifying Party shall, without the written consent of the
Indemnified Holder (which consent shall not be unreasonably withheld), effect
the settlement or compromise of, or consent to the entry of any judgment with
respect to, any pending or threatened action or claim in respect of which
indemnification or contribution may be sought hereunder (whether or not the
Indemnified Holder is an actual or potential party to such action or claim)
unless such settlement, compromise or judgment includes an unconditional release
of the Indemnified Holder from all liability arising out of such action or
claim.

                  (d) Contribution. In order to provide for just and equitable
contribution in circumstances in which the indemnity agreement provided for in
the preceding part of this Section 5 is for any reason held to be unavailable to
an indemnified Holder or is insufficient to hold harmless an indemnified party,
then each Indemnifying Party shall contribute to the damages paid by the
Indemnified Holder, and the Indemnifying Party shall contribute to the damages
paid by the Indemnified Holder provided, however, that 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 misrepresenta tion. In determining the amount of
contribution to which the respective parties are entitled, there shall be
considered the relative fault of the Indemnifying Party and the Indemnified
Holder in connection with the statements or omissions which resulted in such
losses, claims, damages or liabilities (or actions in respect thereof), as well
as any other relevant equitable considerations. The relative fault of such
Indemnifying Party and Indemnified Holder shall be determined by reference to,
among other things, 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 such Indemnifying Party or by such Indemnified Holder,
and the parties' relative intent, knowledge, access to information and
opportunity to correct or prevent such statement or omission. The parties agree
that it would not be just and equitable if contribution pursuant to this Section
5(d) were determined by pro rata or per capita allocation (even if the Electing
Holders or any underwriters, selling agents or other securities professionals or
all of them were treated as one entity for such purpose) or by any other method
of allocation which does not take account of the equitable considerations
referred to in this Section 5(d). The amount paid or payable by an indemnified
party as a result of the losses, claims, damages or liabilities (or actions in
respect thereof) referred to above shall be deemed to include any legal or other
fees or expenses reasonably incurred by such Indemnified Party in connection
with


                                       13

<PAGE>   14



investigating or defending any such action or claim. The obligations of the
Electing Holders and any underwriters, selling agents or other securities
professionals in this Section 5(d) to contribute shall be several in proportion
to the percentage of principal amount of Registrable Securities registered or
underwritten, as the case may be, by them and not joint.

                  (e) Notwithstanding any other provision of this Section 5, in
no event will any (i) Electing Holder be liable to any person under this Section
5 for any amounts in excess of the dollar amount of the proceeds to be received
by such holder from the sale of such holder's Registrable Securities (after
deducting any fees, discounts and commissions applicable thereto) pursuant to
any Shelf Registration Statement under which such Registrable Securities are to
be registered under the Securities Act and (ii) underwriter, selling agent or
other securities professional be liable to any person hereunder for any amounts
in excess of the discount, commission or other compensation payable to such
underwriter, selling agent or other securities professional with respect to the
Registrable Securities underwritten by it and distributed to the public,

                  (f) The obligations of the Company and the Trust under this
Section 5 shall be in addition to any liability which the Company and the Trust
may otherwise have to any Indemnified Person and the obligations of any
Indemnified Person under this Section 5 shall be in addition to any liability
which such Indemnified Person may otherwise have and shall extend, upon the same
terms and conditions, to each officer and director of the Company, each
Administrative Trustee of the Trust and to each person, if any, who controls the
Trust or the Company within the meaning of the Act. The remedies provided in
this Section 5 are not exclusive and shall not limit any rights or remedies
which may otherwise be available to an indemnified party at law or in equity.

                  6. Underwritten Offering. Any Electing Holder of Registrable
Securities who desires to do so may sell Registrable Securities (in whole or in
part) in an underwritten offering; provided that (i) the Holders of at least a
majority in aggregate principal amount of the outstanding Registrable Securities
shall request such an offering and (ii) at least such aggregate principal amount
of such Registrable Securities shall be included in such offering. Upon receipt
of such a request, the Company and the Trust shall provide all Holders of
Registrable Securities written notice of the request, which notice shall inform
such Holders that they have the opportunity to participate in the offering. In
any such underwritten offering, the investment banker or bankers and manager or
managers that will administer the offering will be selected by, and the
underwriting arrangements with respect thereto (including, subject to clause
(ii) above, the size of the offering) will be approved by the Holders of a
majority of the Registrable Securities to be included in such offering,
provided, however, that such investment bankers and managers and underwriting
arrangements must be reasonably satisfactory to the Company and the Trust. No
Holder may participate in any underwritten offering contemplated hereby unless
(a) such Holder agrees to sell such Holder's Registrable Securities to be
included in the underwritten offering in accordance with any approved
underwriting arrangements, (b) such Holder completes and executes all reasonable
questionnaires, powers of attorney, indemnities, underwriting agreements,
lock-up letters and other documents required under the terms of such approved
underwriting arrangements, and (c) if such Holder is not then an Electing
Holder, such Holder returns a completed and signed Notice and Questionnaire to
the Company and the Trust in accordance with Section 3(a)(2) hereof (but in no
event later than 10 days prior to commencement of the underwritten offering) and
provides to the Trust and the Company, in writing, any information with respect
to such Holder or the Registrable Securities held by such Holder as is, in the
reasonable opinion of counsel to the Trust or the Company, required under
applicable law to enable such Holder to use such Prospectus for resales of such
Registrable Securities, each within a reasonable amount of time before such
underwritten offering. The Holders participating in any underwritten offering
shall be responsible for any underwriting discounts and commissions and fees
and, subject to Section 4 hereof, expenses of their own


                                       14

<PAGE>   15



counsel. The Company and the Trust shall pay all expenses customarily borne by
issuers, including but not limited to filing fees, the fees and disbursements of
its counsel and independent public accountants and any printing expenses
incurred in connection with such underwritten offering. Notwithstanding the
foregoing or the provisions of Section 3(n) hereof, upon receipt of a request
from the Managing Underwriter or a representative of Holders of a majority of
the Registrable Securities to be included in an underwritten offering to prepare
and file an amendment or supplement to the Shelf Registration Statement and
Prospectus in connection with an underwritten offering, the Company and the
Trust may delay the filing of any such amendment or supplement for up to 90 days
if the Board of Directors of the Company shall have determined in good faith
that the Company has a bona fide business reason for such delay.

                  7.  Miscellaneous.

                  (a) Amendments and Waivers. This Agreement, including this
Section 7(a), may be amended, and waivers or consents to departures from the
provisions hereof may be given, only by a written instrument duly executed by
the Company and the Holders of a majority in aggregate principal amount of
Registrable Securities then outstanding. Each Holder of Registrable Securities
outstanding at the time of any such amendment, waiver or consent or thereafter
shall be bound by any amendment, waiver or consent effected pursuant to this
Section 7(a), whether or not any notice, writing or marking indicating such
amendment, waiver or consent appears on the Registrable Securities or is
delivered to such Holder.

                  (b) Notices. All notices and other communications provided for
or permitted hereunder shall be made in writing by hand-delivery, first-class
mail, telex, telecopier, or air courier guaranteeing overnight delivery:

                           (i)   if to a Holder, at such address set forth on
         the record books of the Company or the Trust, as the case may be;

                           (ii)  if to the Initial Purchasers, initially at the
         address set forth in the Purchase Agreement; and

                           (iii) if to the Company or the Trust, initially at
         its address set forth in the Purchase Agreement.

All such notices and communications shall be deemed to have duly given when
received.

                  The Initial Purchasers or the Company and the Trust by notice
to the other may designate additional or different addresses for subsequent
notices or communications.

                  (c) Parties in Interest. The parties to this Registration
Rights Agreement intend that all Holders of Registrable Securities shall be
entitled to receive the benefits of this Registration Rights Agreement and that
any Electing Holder shall be bound by the terms and provisions of this
Registration Rights Agreement by reason of such election with respect to the
Registrable Securities which are included in a Shelf Registration Statement. All
the terms and provisions of this Registration Rights Agreement shall be binding
upon, shall inure to the benefit of and shall be enforceable by the respective
successors and assigns of the parties hereto and any Holder from time to time of
the Registrable Securities to the aforesaid extent. In the event that any
transferee of any Holder of Registrable Securities shall acquire Registrable
Securities, in any manner, whether by gift, bequest, purchase, operation of law
or otherwise, such transferee shall, without any further writing or action of
any kind, be entitled to receive the benefits of and,


                                       15

<PAGE>   16



if an Electing Holder, be conclusively deemed to have agreed to be bound by and
to perform all of the terms and provisions of this Registration Rights Agreement
to the aforesaid extent.

                  (d) Counterparts. This Registration Rights Agreement may be
executed in any number of counterparts and by the parties hereto in separate
counterparts, each of which when so executed shall be deemed to be an original
and all of which taken together shall constitute one and the same agreement.

                  (e) Headings. The headings in this Registration Rights
Agreement are for convenience of reference only and shall not limit or otherwise
affect the meaning hereof.

                  (f) Governing Law. This Registration Rights Agreement shall be
governed by and construed in accordance with the laws of the State of New York,
without giving effect to any provisions relating to conflicts of laws.

                  (g) Severability. In the event that any one or more of the
provisions contained herein, or the application thereof in any circumstances, is
held invalid, illegal or unenforceable in any respect for any reason, the
validity, legality and enforceability of any such provision in every other
respect and of the remaining provisions hereof shall not be in any way impaired
or affected thereby, it being intended that all of the rights and privileges of
the parties hereto shall be enforceable to the fullest extent permitted by law.

                  8. No Liability of Property Trustee, Delaware Trustee or
Guarantee Trustee.

                  It is expressly understood and agreed by the parties hereto
that (a) each of the representations, undertakings and agreements herein made on
the part of the Trust is made and intended not as representations, warranties,
covenants, undertakings and agreements of any Trustee of the Trust, including,
without limitation, Chase Bank of Texas, National Association as Guarantee
Trustee or Property Trustee or Chase Manhattan Bank Delaware as Delaware
Trustee, in their individual capacity, but is made and intended for the purpose
of binding only the Trust, and (b) under no circumstances shall any Trustee,
including Chase Bank of Texas, National Association as Guarantee Trustee or
Property Trustee or Chase Manhattan Bank Delaware as Delaware Trustee be
personally liable for any breach or failure of any obligation, representation,
warranty, or covenant made or undertaken by the Trust under this Agreement
except if such breach or failure is due to any gross negligence or wilful
misconduct of the Trustee.

SECTION 3.1.      Limitation of Transactions

                  So long as any Common Securities remain outstanding, if (i)

Convertible Debentures by extending the interest payment period and such
extension shall be continuing, (ii) if there shall have occurred any Event of
Default under this Common Securities Guarantee, or (iii) there shall have
occurred and be continuing any event that, with the giving of notice or the
lapse of time or both, would constitute an Indenture Event of Default, then the
Guarantor has agreed (a) not to declare or pay dividends on, make a
distribution with respect to, or redeem, purchase, acquire or make a liquidation
payment with respect to, any of its capital stock (other than (i) purchases or
acquisitions of shares of common stock in connection with the satisfaction by
the Guarantor of its obligations under any employee benefit plans or the

converted or exchanged (or make any guarantee payments with respect to the
foregoing), (b) not to make any payment of interest, principal or premium, if
any, on or repay, repurchase or redeem any debt securities of the Company that
rank pari passu with or junior to the Convertible Debentures (except by
conversion into or exchange for shares of its capital stock), and 


                                        6

pursuant to this Common Securities Guarantee).

SECTION 3.2.      Ranking

                  (a)      This Common Securities Guarantee will constitute an
unsecured obligation of the Guarantor and will rank (i) subordinate and junior
to all other liabilities of the Guarantor except any liabilities that may be
pari passu expressly by their terms, (ii) pari passu with the most senior
preferred stock issued from time to time by the Guarantor and with any guarantee
now or hereafter entered into by the Guarantor in respect of any preferred or
preference stock or preferred securities of any affiliate of the Guarantor and
(iii) senior to the Guarantor's common stock.

                  (b)      The holders of any obligations of the Guarantor that
are senior in priority to the obligations under this Common Securities Guarantee
will be entitled to all of the rights inuring to the holders of "Senior
Indebtedness" under Article 12 of the Indenture, and the holders of the
