Item 15. Indemnification of Officers and Directors.

 ACE

  Section 100 of ACE's Articles of Association, filed as Exhibit 4.2 to this
registration statement, contains provisions with respect to indemnification of
ACE's officers and directors. Such provision provides that ACE shall indemnify,
in accordance with and to the full extent now or hereafter permitted by law,
any 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 (including, without limitation, an
action by or in the right of ACE), by reason of his acting as a director,
officer, employee or agent of, or his acting in any other capacity for or on
behalf of, ACE, against any liability or expense actually and reasonably
incurred by such person in respect thereof. ACE may also advance the expenses
of defending any such act, suit or proceeding in accordance with and to the
full extent now or hereafter permitted by law. Such indemnification and
advancement of expenses are not exclusive of any other right to indemnification
or advancement of expenses provided by law or otherwise.

  The Companies Law (Revised) of the Cayman Islands does not set out any
specific restrictions on the ability of a company to indemnify officers or
directors. However, the application of basic principles and certain
Commonwealth case law which is likely to be persuasive in the Cayman Islands
would indicate that indemnification is generally permissible except in the
event that there had been fraud or wilful default on the part of the officer or
director or reckless disregard of his duties and obligations to the company.

  Directors and officers of ACE are also provided with indemnification against
certain liabilities pursuant to a directors and officers liability insurance
policy. Coverage is afforded for any loss that the insureds become legally
obligated to pay by reason of any claim or claims first made against the
insureds or any of them during the policy period from any wrongful acts that
are actually or allegedly caused, committed or attempted by the insureds prior
to the end of the policy period. Wrongful acts are defined as any actual or
alleged error, misstatement misleading statement or act, omission, neglect or
breach of duty by the insureds while acting in their individual or collective
capacities as directors or officers of ACE, or any other matter claimed against
them by reason of their being directors or officers of ACE. Certain of ACE's
directors are provided, by their employer, with indemnification against certain
liabilities incurred as directors of ACE.

  Reference is made to the forms of Underwriting Agreement filed as Exhibits
1.1 though 1.3 of this registration statement. The Underwriting Agreements
provide, among other things, that the underwriters are obligated, under certain
circumstances, to indemnify directors, certain officers and controlling persons
of ACE against certain liabilities, including liabilities under the Securities
Act of 1933, as amended.

 ACE INA

  Section 102(b)(7) of the Delaware General Corporation Law permits a
corporation to provide in its certificate of incorporation that a director of
the corporation shall not be personally liable to the corporation or its
stockholders for monetary damages for breach of fiduciary duty as a director,
except for liability (i) for any breach of the director's duty of loyalty to
the corporation or its stockholders, (ii) for acts of omissions not in good
faith or which involve intentional misconduct or a knowing violation of law,
(iii) for payments of unlawful dividends or unlawful stock repurchases or
redemptions or (iv) for any transaction from which the director derived an
improper personal benefit. ACE INA's Certificate of Incorporation contains such
a provision.

  Under Article VI of ACE INA's By-laws as currently in effect, as well as
under Section 10 of ACE INA's Certificate of Incorporation, each person who is
or was a director or officer of ACE INA, or who serves or served any other
enterprise or organization at the request of ACE INA, shall be indemnified by
ACE INA to the full extent permitted by the Delaware General Corporation Law.

  Section 145 of the Delaware General Corporation Law provides that a
corporation may indemnify any person who, by reason of the fact that such
person is or was a director or officer of such corporation, is made (or
threatened to be made) a party to an action other than one brought by or on
behalf of the corporation, against reasonable expenses (including attorneys'
fees), judgments, fines and settlement payments, if such person acted in good
faith and in a manner he reasonably believed to be in or not opposed to the
best interests of such corporation and, in criminal actions, in addition, had
no reasonable cause to believe his conduct was unlawful. In the case of actions
on behalf of the corporation, indemnification may extend only to reasonable
expenses (including attorneys' fees) and only if such person acted in good
faith and in a manner he reasonably believed to be in or not opposed to the
best interests of the corporation, provided that no such indemnification is
permitted in respect of any claim as to which such person is adjudged liable to
such corporation for negligence or misconduct in the performance of his duty to
the corporation unless and only to the extent that a court otherwise provides.
To the extent that such person has been successful in defending any action
(even one on behalf of the corporation), he is entitled to indemnification for
reasonable expenses (including attorneys' fees).

  The indemnification provided for by the Delaware General Corporation Law is
not exclusive of any other rights of indemnification, and a corporation may
maintain insurance against liabilities for which indemnification is not
expressly provided by the Delaware General Corporation Law. ACE INA maintains a
liability insurance policy providing coverage for its directors and officers.

  Reference is made to the forms of Underwriting Agreements filed as Exhibits
1.2 and 1.3 of this registration statement. The Underwriting Agreements
provide, among other things, that the underwriters are obligated, under certain
circumstances, to indemnify directors, certain officers and controlling persons
of ACE INA against certain liabilities, including liabilities under the
Securities Act of 1933, as amended.

Item 16. Exhibits and Financial Statement Schedules.

  See Exhibit Index included herewith which is incorporated herein by
reference.

Item 17. Undertakings.

  The undersigned registrants hereby undertake:

  (a) To file, during any period in which offers or sales are being made, a
      post-effective amendment to this registration statement:

<TABLE>
     <C>  <S>
     (i)  To include any prospectus required by Section 10(a)(3) of the
          Securities Act of 1933;

     (ii) To reflect in the prospectus any facts or events arising after the
          effective date of the registration statement (or the most recent
          post-effective amendment thereof) which, individually or in the
          aggregate, represent a fundamental change in the information set
          forth in the registration statement. Notwithstanding the foregoing,
          any increase or decrease in volume
</TABLE>

                                      II-2
<PAGE>

<TABLE>
     <C>   <S>
           of securities offered (if the total dollar value of securities
           offered would not exceed that which was registered) and any
           deviation from the low or high end of the estimated maximum offering
           range may be reflected in the form of prospectus filed with the
           Commission pursuant to Rule 424(b) if, in the aggregate, the changes
           in volume and price represent no more than a 20 percent change in
           the maximum aggregate offering price set forth in the "Calculation
           of Registration Fee" table in the effective registration statement;

     (iii) To include any material information with respect to the plan of
           distribution not previously disclosed in the registration statement
           or any material change to such information in the registration
           statement;
</TABLE>

    provided, however, that paragraphs (a)(i) and (a)(ii) do not apply if
    the information required to be included in a post-effective amendment
    by those paragraphs is contained in periodic reports filed with the
    Commission by the registrants pursuant to Section 13 or 15(d) of the
    Securities Exchange Act of 1934 that are incorporated by reference in
    the registration statement.

  (b) That, for the purpose of determining any liability under the Securities
      Act of 1933, each such post-effective amendment 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.

  (c) To remove from registration by means of a post-effective amendment any
      of the securities being registered which remain unsold at the
      termination of the offering.

  The undersigned registrants hereby undertake that, for purposes of
determining any liability under the Securities Act of 1933, each filing of
ACE's annual report pursuant to Section 13(a) or 15(d) of the Securities
Exchange Act of 1934 (and, where applicable, each filing of an employee benefit
plan's annual report pursuant to Section 15(d) of the Securities Exchange Act
of 1934) 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.

  The undersigned registrants hereby undertake that:

  (a) For purposes of determining any liability under the Securities Act of
      1933, 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 registrants 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; and

  (b) For the purpose of determining any liability under the Securities Act
      of 1933, 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.

  Insofar as indemnification for liabilities arising under the Securities Act
of 1933 may be permitted to directors, officers or persons controlling the
registrants pursuant to the provisions set forth or described in Item 15 of
this registration statement, or otherwise, the registrants have been informed
that in the opinion of the Securities and Exchange 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 a registrant of expenses
incurred or paid by a director, officer or controlling person of such
registrant in the successful defense of any action, suit or proceeding) is
asserted by such director, officer or controlling person in connection with the
securities being registered, the registrants will, unless in the opinion of
their counsel the matter has been settled by controlling precedent, submit to a
court of appropriate jurisdiction the question whether such indemnification by
them is against public policy as expressed in the Securities Act of 1933 and
will be governed by the final adjudication of such issue.

                            (a Delaware corporation)

                    Senior and Subordinated Debt Securities

                  Unconditionally Guaranteed as to Payment of
                  Principal, Premium, if any, and Interest by

                                  ACE LIMITED

                             UNDERWRITING AGREEMENT

                                                               ___________, 1999

To:  The Underwriters named in the
     within-mentioned Terms Agreement

Ladies and Gentlemen:

     ACE INA Holdings Inc., a Delaware corporation (the "Company"), proposes to
issue and sell up to $4,000,000,000 aggregate initial public offering price, or
its equivalent based on the applicable exchange rate at the time of offering in
such foreign or composite currencies as the Company shall designate at the time
of offering, of its senior or subordinated debt securities (the "Debt
Securities"), from time to time, in or pursuant to one or more offerings on
terms to be determined at the time of sale.  The Debt Securities will be
unconditionally guaranteed as to payment of principal, premium, if any, and
interest by ACE Limited, a Cayman Islands company (the "Guarantor").

     The Debt Securities will be issued in one or more series as senior
indebtedness (the "Senior Debt Securities") under an indenture, dated as of
____________, 1999 (the "Senior Indenture"), among the Company, the Guarantor
and The First National Bank of Chicago, as trustee (the "Senior Trustee"), or as
subordinated indebtedness (the "Subordinated Debt Securities") under an
indenture, dated as of ____________, 1999 (the "Subordinated Indenture", and
collectively with the Senior Indenture, the "Indentures", and each, an
"Indenture"), between the Company, the Guarantor and The First National Bank of
Chicago, as trustee (the "Subordinated Trustee", and collectively with the
Senior Trustee, the "Trustees", and each, a "Trustee").  Each series of Debt
Securities may vary, as applicable, as to title, aggregate principal amount,
rank, interest rate or formula and timing of payments thereof, stated maturity
date, redemption and/or repayment provisions, sinking fund requirements,
conversion or exchange provisions and any other variable terms established by or
pursuant to the applicable Indenture.

     Whenever the Company determines to make an offering of Debt Securities, the
Company and the Guarantor will enter into an agreement (each, a "Terms
Agreement") providing for the sale of such Debt Securities to, and the purchase
and offering thereof by, the underwriters specified in the Terms Agreement (the
"Underwriters", which term shall include any Underwriter substituted pursuant to
Section 10 hereof).  The Terms Agreement relating to the offering of Debt
Securities shall specify the aggregate principal amount of Debt Securities to be
<PAGE>

issued (the "Underwritten Securities"), the name of each Underwriter
participating in such offering (subject to substitution as provided in Section
10 hereof) and the name of any Underwriter acting as co-manager in connection
with such offering, the aggregate principal amount of Underwritten Securities
which each such Underwriter severally agrees to purchase, whether such offering
is on a fixed or variable price basis and, if on a fixed price basis, the
initial offering price, the price at which the Underwritten Securities are to be
purchased by the Underwriters, the form, time, date and place of delivery and
payment of the Underwritten Securities and any other material variable terms of
the Underwritten Securities. The Terms Agreement, which shall be substantially
in the form of Exhibit A hereto, may take the form of an exchange of any
standard form of written telecommunication between the Company and one or more
of the Underwriters, acting for themselves and, if applicable, as
representative(s) of any other Underwriters.  Each offering of Underwritten
Securities will be governed by this Underwriting Agreement, as supplemented by
the applicable Terms Agreement.  As used herein, the term "Representative(s)"
means, with respect to any offering of Debt Securities, any Underwriter
specified as the representative of the Underwriters of such offering in the
applicable Terms Agreement and if none is so designated, it means the
Underwriters.

     The Company and the Guarantor have filed with the Securities and Exchange
Commission (the "Commission") a joint registration statement on Form S-3 (No.
333-78841) and pre-effective amendments nos. 1 and 2 thereto, for the
registration of the Debt Securities and the guarantee thereof of the Guarantor
(the "Guarantee") under the Securities Act of 1933, as amended (the "1933 Act"),
and the offering thereof from time to time in accordance with Rule 415 of the
rules and regulations of the Commission under the 1933 Act (the "1933 Act
Regulations").  Such registration statement has been declared effective by the
Commission and each Indenture has been duly qualified under the Trust Indenture
Act of 1939, as amended (the "1939 Act"), and the Company and the Guarantor have
filed such post-effective amendments thereto as may be required prior to the
execution of the applicable Terms Agreement and each such post-effective
amendment has been declared effective by the Commission.  Such registration
statement (as so amended, if applicable), including the information, if any,
deemed to be a part thereof pursuant to Rule 430A(b) of the 1933 Act Regulations
(the "Rule 430A Information") or Rule 434(d) of the 1933 Act Regulations (the
"Rule 434 Information"), is referred to herein as the "Registration Statement";
and the final prospectus and the final prospectus supplement relating to the
offering of the Underwritten Securities, in the form first furnished to the
Underwriters by the Company and the Guarantor for use in connection with the
offering of the Underwritten Securities, are collectively referred to herein as
the "Prospectus"; provided, however, that all references to the "Registration
Statement" and the "Prospectus" shall also be deemed to include all documents
incorporated therein by reference pursuant to the Securities Exchange Act of
1934, as amended (the "1934 Act"), prior to the execution of the applicable
Terms Agreement; provided, further, that if the Company and the Guarantor file a
registration statement with the Commission pursuant to Rule 462(b) of the 1933
Act Regulations (the "Rule 462(b) Registration Statement"), then, after such
filing, all references to "Registration Statement" shall also be deemed to
include the Rule 462 Registration Statement; and provided, further, that if the
Company and the Guarantor elect to rely upon Rule 434 of the 1933 Act
Regulations, then all references to "Prospectus" shall also be deemed to include
the final or preliminary prospectus and the applicable term sheet or abbreviated
term sheet (the "Term Sheet"), as the case may be, in the form first furnished
to the Underwriters by the Company and the Guarantor in reliance upon Rule 434
of the 1933 Act Regulations, and all references in this

                                       2
<PAGE>

Underwriting Agreement to the date of the Prospectus shall mean the date of the
Term Sheet. A "preliminary prospectus" shall be deemed to refer to any
prospectus used before the Registration Statement became effective and any
prospectus that omitted, as applicable, the Rule 430A Information, the Rule 434
Information or other information to be included upon pricing in a form of
prospectus filed with the Commission pursuant to Rule 424(b) of the 1933 Act
Regulations and was used after such effectiveness and prior to the execution and
delivery of the applicable Terms Agreement. For purposes of this Underwriting
Agreement, all references to the Registration Statement, Prospectus, Term Sheet
or preliminary prospectus or to any amendment or supplement to any of the
foregoing shall be deemed to include any copy filed with the Commission pursuant
to its Electronic Data Gathering, Analysis and Retrieval system ("EDGAR").

     All references in this Underwriting Agreement to financial statements and
schedules and other information which is "contained," "included" or "stated" (or
other references of like import) in the Registration Statement, Prospectus or
preliminary prospectus shall be deemed to mean and include all such financial
statements and schedules and other information which is incorporated by
reference in the Registration Statement, Prospectus or preliminary prospectus,
as the case may be, prior to the execution of the applicable Terms Agreement;
and all references in this Underwriting Agreement to amendments or supplements
to the Registration Statement, Prospectus or preliminary prospectus shall be
deemed to mean and include the filing of any document under the 1934 Act which
is incorporated by reference in the Registration Statement, Prospectus or
preliminary prospectus, as the case may be, after the execution of the
applicable Terms Agreement.

  SECTION 1.   Representations and Warranties.
               ------------------------------

  (a) Representations and Warranties by the Company and the Guarantor.  The
Company and the Guarantor represent and warrant to each Underwriter named in the
applicable Terms Agreement, as of the date thereof and as of the Closing Time
(as defined below) (in each case, a "Representation Date"), as follows:

        (1) Compliance with Registration Requirements.  The Company and the
            -----------------------------------------
     Guarantor meet the requirements for use of Form S-3 under the 1933 Act.
     The Registration Statement (including any Rule 462(b) Registration
     Statement) has become effective under the 1933 Act and no stop order
     suspending the effectiveness of the Registration Statement (or such Rule
     462(b) Registration Statement) has been issued under the 1933 Act and no
     proceedings for that purpose have been instituted or are pending or, to the
     knowledge of the Company or the Guarantor, are contemplated by the
     Commission, and any request on the part of the Commission for additional
     information has been complied with.  In addition, each Indenture has been
     duly qualified under the 1939 Act.

          At the respective times the Registration Statement (including any Rule
     462(b) Registration Statement) and any post-effective amendments thereto
     (including the filing of the Guarantor's most recent Annual Report on Form
     10-K with the Commission (the "Annual Report on Form 10-K")) became
     effective and at each Representation Date, the Registration Statement
     (including any Rule 462(b) Registration Statement) and any

                                       3
<PAGE>

     amendments thereto complied and will comply in all material respects with
     the requirements of the 1933 Act and the 1933 Act Regulations and the 1939
     Act and the rules and regulations of the Commission under the 1939 Act (the
     "1939 Act Regulations") and did not and will not 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. At the date of the Prospectus and at the Closing Time, neither
     the Prospectus nor any amendments and supplements thereto included or will
     include an untrue statement of a material fact or omitted or will 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.
     If the Company and the Guarantor elect to rely upon Rule 434 of the 1933
     Act Regulations, the Company and the Guarantor will comply with the
     requirements of Rule 434. Notwithstanding the foregoing, the
     representations and warranties in this subsection shall not apply to
     statements in or omissions from the Registration Statement or the
     Prospectus made in reliance upon and in conformity with information
     furnished to the Company or the Guarantor in writing by any Underwriter
     through the Representative(s) expressly for use in the Registration
     Statement or the Prospectus.

          Each preliminary prospectus and prospectus filed as part of the
     Registration Statement as originally filed or as part of any amendment
     thereto, or filed pursuant to Rule 424 under the 1933 Act, complied when so
     filed in all material respects with the 1933 Act Regulations and each
     preliminary prospectus and the Prospectus delivered to the Underwriters for
     use in connection with the offering of Underwritten Securities will, at the
     time of such delivery, be identical to any electronically transmitted
     copies thereof filed with the Commission pursuant to EDGAR, except to the
     extent permitted by Regulation S-T.

        (2) Incorporated Documents.  The documents incorporated or deemed to be
            ----------------------
     incorporated by reference in the Registration Statement and the Prospectus,
     at the time they were or hereafter are filed with the Commission, complied
     and will comply in all material respects with the requirements of the 1934
     Act and the rules and regulations of the Commission thereunder (the "1934
     Act Regulations") and, when read together with the other information in the
     Prospectus, at the date of the Prospectus and at the Closing Time, did not
     and will not include an untrue statement of a material fact or omit to
     state a material fact necessary in order to make the statements therein, in
     the light of the circumstances under which they were made, not misleading.

        (3) Independent Accountants.  The accountants who certified or shall
            -----------------------
     certify the financial statements and any supporting schedules thereto of
     the Guarantor and the CIGNA Corporation Property and Casualty Businesses
     (the "CIGNA Businesses") included in the Registration Statement and the
     Prospectus are independent public accountants with respect to the Guarantor
     and its subsidiaries and with respect to the CIGNA Businesses, as the case
     may be, as required by the 1933 Act and the 1933 Act Regulations.

        (4) Financial Statements.  The financial statements of the Guarantor
            --------------------
     included in the Registration Statement and the Prospectus, together with
     the related schedules and

                                       4
<PAGE>

     notes, as well as those financial statements, schedules and notes of any
     other entity included therein, present fairly the financial position of the
     Guarantor and its consolidated subsidiaries, or such other entity, as the
     case may be, at the dates indicated and the statement of operations,
     stockholders' equity and cash flows of the Guarantor and its consolidated
     subsidiaries, or such other entity, as the case may be, for the periods
     specified. Such financial statements have been prepared in conformity with
     United States generally accepted accounting principles ("GAAP") applied on
     a consistent basis throughout the periods involved, except as indicated
     therein or in the notes thereto. The financial statements of the CIGNA
     Businesses included in the Registration Statement and the Prospectus,
     together with the related schedules and notes, present fairly the combined
     financial position of the CIGNA Businesses at the dates indicated and the
     combined statement of income, comprehensive income and invested equity and
     cash flows of the CIGNA Businesses for the periods specified; said
     financial statements have been prepared in conformity with GAAP applied on
     a consistent basis throughout the periods involved, except as indicated
     therein or in the notes thereto. The supporting schedules, if any, included
     in the Registration Statement and the Prospectus present fairly in
     accordance with GAAP the information required to be stated therein. The
     selected financial data and the summary financial information, if any,
     included in the Prospectus present fairly the information shown therein and
     have been compiled on a basis consistent with that of the related audited
     financial statements included in the Registration Statement and the
     Prospectus. The pro forma financial statements of the Guarantor and its
     subsidiaries and the related notes thereto included in the Registration
     Statement and the Prospectus present fairly the information shown therein,
     have been prepared in accordance with the Commission's rules and guidelines
     with respect to pro forma financial statements and have been properly
     compiled on the bases described therein, and the assumptions used in the
     preparation thereof are reasonable and the adjustments used therein are
     appropriate to give effect to the transactions and circumstances referred
     to therein.

        (5) No Material Adverse Change in Business.  Since the respective dates
            --------------------------------------
     as of which information is given in the Registration Statement and the
     Prospectus, except as otherwise stated therein (i) neither the Guarantor
     nor any of its subsidiaries (including the Company) has sustained any
     material loss or material interference with its business from any action,
     notice, order or decree from an insurance regulatory authority and (ii)
     there has been (A) no material adverse change in case reserves or losses or
     loss expense of the Guarantor and its consolidated subsidiaries (including
     the Company) and (B) no material adverse change, nor any development or
     event involving a prospective material adverse change, in the financial
     condition, business, or results of operations of the Guarantor and its
     subsidiaries (including the Company) considered as one enterprise, in
     either case whether or not arising in the ordinary course of business (a
     "Material Adverse Change").

        (6) Good Standing of the Company.  The Company has been duly
            ----------------------------
     incorporated and is subsisting and in good standing under the laws of the
     State of Delaware, with corporate power and authority to own, lease and
     operate its properties and to conduct its business as described in the
     Prospectus and to enter into and perform its obligations under, or as
     contemplated under, this Underwriting Agreement and the applicable Terms
     Agreement.  The Company is duly qualified to transact business as a foreign
     corporation

                                       5
<PAGE>

     and is in good standing in all other jurisdictions in which its ownership
     or lease of property or the conduct of its business requires such
     qualification, except where the failure to so qualify or be in good
     standing would not reasonably be expected to result in a Material Adverse
     Change.

        (7) Good Standing of the Guarantor.  The Guarantor has been duly
            ------------------------------
     organized and is subsisting and in good standing under the laws of the
     Cayman Islands, with corporate power and authority to own, lease and
     operate its properties and to conduct its business as described in the
     Prospectus and to enter into and perform its obligations under, or as
     contemplated under, this Underwriting Agreement and the applicable Terms
     Agreement. The Guarantor is duly qualified to transact business as a
     foreign corporation and is in good standing in all other jurisdictions in
     which its ownership or lease of property or the conduct of its business
     requires such qualification, except where the failure to so qualify or be
     in good standing would not reasonably be expected to result in a Material
     Adverse Change.

        (8) Good Standing of Corporate Subsidiaries.  Each subsidiary of the
            ---------------------------------------
     Guarantor, other than such subsidiaries as would not, individually or in
     the aggregate, constitute a "significant subsidiary" as such term is
     defined in Rule 1-02 of Regulation S-X promulgated under the 1933 Act
     (each, a "Significant Subsidiary") (including the Company) which is a
     corporation has been duly incorporated or organized and is an existing
     corporation in good standing (with respect to jurisdictions which recognize
     such concept) under the laws of the jurisdiction of its incorporation, with
     corporate power and authority to own, lease and operate its properties and
     to conduct its business as described in the Prospectus; and each such
     Significant Subsidiary of the Guarantor is duly qualified to transact
     business as a foreign corporation and is in good standing (with respect to
     jurisdictions which recognize such concept) in all other jurisdictions in
     which its ownership or lease of property or the conduct of its business
     requires such qualification, except where the failure to so qualify or be
     in good standing would not reasonably be expected to result in a Material
     Adverse Change; all of the issued and outstanding capital stock of each
     such Significant Subsidiary of the Guarantor has been duly authorized and
     validly issued and is fully paid and nonassessable; and all of the issued
     and outstanding capital stock of each such Significant Subsidiary is owned
     by the Guarantor, directly or through subsidiaries, except for de minimis
     shareholdings as required to comply with applicable law, and such capital
     stock is owned free and clear of any security interest, mortgage, pledge,
     lien, encumbrance, claim or equity (except for restrictions on
     transferability of the shares of insurance subsidiaries, under applicable
     law).

        (9) Good Standing of Partnership Subsidiaries.  Each Significant
            -----------------------------------------
     Subsidiary of the Guarantor which is a partnership has been duly formed and
     is an existing partnership in good standing (with respect to jurisdictions
     which recognize such concept) under the laws of the jurisdiction of its
     formation, with power and authority to own, lease and operate its
     properties and to conduct its business as described in the Prospectus; and
     each such Significant Subsidiary of the Guarantor is duly qualified to
     transact business and is in good standing (with respect to jurisdictions
     which recognize such concept) in all other jurisdictions in which its
     ownership or lease of property or the conduct of its business requires such
     qualification, except where the failure to so qualify or be in good
     standing

                                       6
<PAGE>

     would not reasonably be expected to result in a Material Adverse Change;
     all of the outstanding equity interests of each such Significant Subsidiary
     of the Guarantor have been duly authorized and validly issued; and all of
     the equity interests of each such Significant Subsidiary are owned by the
     Guarantor, directly or through subsidiaries, free and clear of any security
     interest, mortgage, pledge, lien, encumbrance, claim or equity (other than
     immaterial amounts necessary to comply with applicable law).

        (10) Capitalization.  If the Prospectus contains a "Capitalization"
             --------------
     section, the authorized, issued and outstanding shares of capital stock of
     the Guarantor are as set forth in the column entitled "Actual" under such
     section (except for subsequent issuances thereof, if any, pursuant to
     reservations, agreements or employee benefit plans or pursuant to the
     exercise of convertible securities or options).  Such shares of capital
     stock have been duly authorized and validly issued by the Guarantor and are
     fully paid and non-assessable, and none of such shares of capital stock was
     issued in violation of preemptive or other similar rights of any
     securityholder of the Guarantor.

        (11) Authorization of this Underwriting Agreement and Terms Agreement.
             ----------------------------------------------------------------
     This Underwriting Agreement has been, and the applicable Terms Agreement as
     of the date thereof will have been, duly authorized, executed and delivered
     by the Company and the Guarantor.

        (12) Authorization of Underwritten Securities.  The Underwritten
             ----------------------------------------
     Securities have been, or as of the date of such Terms Agreement will have
     been, duly authorized by the Company for issuance and sale pursuant to this
     Underwriting Agreement and such Terms Agreement.  Such Underwritten
     Securities, when issued and authenticated in the manner provided for in the
     applicable Indenture and delivered against payment of the consideration
     therefor specified in such Terms Agreement, will constitute valid and
     binding obligations of the Company, enforceable against the Company in
     accordance with their terms, except as the enforcement thereof may be
     limited by bankruptcy, insolvency (including, without limitation, all laws
     relating to fraudulent transfers), reorganization, moratorium or other
     similar laws affecting the enforcement of creditors' rights generally or by
     general equitable principles (regardless of whether enforcement is
     considered in a proceeding in equity or at law), and except further as
     enforcement thereof may be limited by requirements that a claim with
     respect to any Underwritten Securities payable in a foreign or composite
     currency (or a foreign or composite currency judgment in respect of such
     claim) be converted into U.S. dollars at a rate of exchange prevailing on a
     date determined pursuant to applicable law or by governmental authority to
     limit, delay or prohibit the making of payments outside the United States.
     Such Underwritten Securities will be in the form contemplated by, and each
     registered holder thereof will be entitled to the benefits of, the
     applicable Indenture.

        (13) Authorization of Guarantee.  The Guarantee has been, or as of the
             --------------------------
     date of such Terms Agreement will have been, duly authorized by the
     Guarantor for issuance and sale pursuant to this Underwriting Agreement and
     the applicable Terms Agreement.  Such Guarantee, when issued and delivered
     in the manner provided for in the applicable Indenture, will constitute a
     valid and binding obligation of the Guarantor, enforceable against the
     Guarantor in accordance with its terms, except as the enforcement thereof

                                       7
<PAGE>

     may be limited by bankruptcy, insolvency (including, without limitation,
     all laws affecting the enforcement of creditors' rights generally or by
     general equitable principles (regardless of whether enforcement is
     considered in a proceeding in equity or at law), and will be in the form
     contemplated by, and entitled to the benefits of, the Indenture.

        (14) Authorization of the Indentures.  The applicable Indenture has
             -------------------------------
     been, or prior to the issuance of the Debt Securities thereunder will have
     been, duly authorized, executed and delivered by the Company and the
     Guarantor and, upon such authorization, execution and delivery, will
     constitute a valid and binding agreement of the Company and the Guarantor,
     enforceable against each of them in accordance with its terms, except as
     the enforcement thereof may be limited by bankruptcy, insolvency
     (including, without limitation, all laws relating to fraudulent transfers),
     reorganization, moratorium or other similar laws affecting the enforcement
     of creditors' rights generally or by general equitable principles
     (regardless of whether enforcement is considered in a proceeding in equity
     or at law).

        (15) Descriptions of the Underwritten Securities, the Guarantee and the
             ------------------------------------------------------------------
     Indentures.  The Underwritten Securities being sold pursuant to the
     ----------
     applicable Terms Agreement, the Guarantee and each applicable Indenture, as
     of each Representation Date, will conform in all material respects to the
     statements relating thereto contained in the Prospectus and will be in
     substantially the form filed or incorporated by reference, as the case may
     be, as an exhibit to the Registration Statement.

        (16) Non-Taxation of Interest.  Except as disclosed in the Prospectus,
             ------------------------
     under current laws and regulations of the Cayman Islands and Bermuda and
     any political subdivision thereof, all interest payable on the Underwritten
     Securities may be paid by the Guarantor pursuant to the Guarantee to the
     holder thereof in United States dollars and freely transferred out of the
     Cayman Islands or Bermuda and all such payments made to holders thereof or
     therein who are non-residents of the Cayman Islands or Bermuda will not be
     subject to income, withholding or other taxes under laws and regulations of
     the Cayman Islands or Bermuda or any political subdivision or taxing
     authority thereof or therein and will otherwise be free and clear of any
     other tax, duty, withholding or deduction in the Cayman Islands or Bermuda
     or any political subdivision or taxing authority thereof or therein and
     without the necessity of obtaining any governmental authorization in the
     Cayman Islands or Bermuda or any political subdivision or taxing authority
     thereof or therein.

        (17) Reserves.  The description of the Guarantor's reserves and
             --------
     reserving methodology and assumptions described in the Prospectus is
     accurate and fairly presents the information set forth therein in all
     material respects and, since the date of the latest financial statements
     included in the Prospectus, no loss experience has developed which would
     require or make it appropriate for the Guarantor to alter or modify such
     methodology.

        (18) Absence of Defaults and Conflicts.  Neither the Guarantor or any of
             ---------------------------------
     its subsidiaries (including the Company) is in violation of its charter or
     by-laws or partnership agreement, as the case may be, or in default in the
     performance or observance

                                       8
<PAGE>

     of any obligation, agreement, covenant or condition contained in any
     contract, indenture, mortgage, deed of trust, loan or credit agreement,
     note, lease or other agreement or instrument to which the Guarantor or any
     of its subsidiaries (including the Company) is a party or by which it or
     any of them may be bound, or to which any of the assets, properties or
     operations of the Guarantor or any of its subsidiaries (including the
     Company) is subject (collectively, "Agreements and Instruments"), except
     for such defaults that would not reasonably be expected to result in a
     Material Adverse Change. The execution, delivery and performance of this
     Underwriting Agreement, the applicable Terms Agreement and each applicable
     Indenture and any other agreement or instrument entered into or issued or
     to be entered into or issued by the Company or the Guarantor in connection
     with the transactions contemplated hereby or thereby or in the Registration
     Statement and the Prospectus, and the consummation of the transactions
     contemplated herein and in the Registration Statement and the Prospectus
     (including, without limitation, the issuance and sale of the Underwritten
     Securities and the Guarantee, and the use of the proceeds from the sale of
     the Underwritten Securities and the Guarantee as described under the
     caption "Use of Proceeds") and compliance by the Company and the Guarantor,
     as applicable, with its obligations hereunder and thereunder have been duly
     authorized by all necessary corporate action and do not and will not,
     whether with or without the giving of notice or passage of time or both,
     conflict with or constitute a breach of, or default or Repayment Event (as
     defined below) under, or result in the creation or imposition of any lien,
     charge or encumbrance upon any assets, properties or operations of the
     Guarantor or any of its subsidiaries (including the Company) pursuant to,
     any Agreements and Instruments (except for such conflicts, breaches,
     defaults or Repayment Events or liens, charges or encumbrances that would
     not reasonably be expected to result in a Material Adverse Change), nor
     will such action result in any violation of the provisions of the charter
     or by-laws or partnership agreement, as the case may be, of the Guarantor
     or any of its subsidiaries (including the Company) or, to the best of the
     Company's and the Guarantor's knowledge, any applicable law, statute, rule,
     regulation, judgment, order, writ or decree of any government, government
     instrumentality or court, domestic or foreign, having jurisdiction over the
     Guarantor or any of its subsidiaries (including the Company) or over any of
     the assets, properties or operations of the Guarantor or any of its
     subsidiaries (including the Company). As used herein, a "Repayment Event"
     means any event or condition which gives the holder of any note, debenture
     or other evidence of indebtedness (or any person acting on such holder's
     behalf) the right to require the repurchase, redemption or repayment of all
     or a portion of such indebtedness by the Guarantor or any of its
     subsidiaries (including the Company).

        (19) Absence of Proceedings.  There is no action, suit, proceeding,
             ----------------------
     inquiry or investigation before or brought by any court or governmental
     agency or body, domestic or foreign, now pending, or to the knowledge of
     the Company or the Guarantor threatened, against or affecting the Guarantor
     or any of its subsidiaries (including the Company) which is required to be
     disclosed in the Registration Statement and the Prospectus (other than as
     stated therein), or which would reasonably be expected to result in a
     Material Adverse Change, or which would reasonably be expected to
     materially and adversely affect the ability of the Company or the Guarantor
     to perform its obligations under this Agreement or the applicable Terms
     Agreement.

                                       9
<PAGE>

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

        (21) Absence of Further Requirements.  No consent, approval,
             -------------------------------
     authorization, or order of, or filing with, any governmental agency or body
     or any court, domestic or foreign, is required for the due authorization,
     execution or delivery by the Company or the Guarantor of this Underwriting
     Agreement or the applicable Terms Agreement or for the performance by the
     Company or the Guarantor of the transactions contemplated under the
     Prospectus, this Underwriting Agreement, such Terms Agreement or the
     applicable Indenture, as applicable, except such as have been obtained and
     made under the Act, such filing of the Prospectus as has been made with the
     Bermuda Registrar of Companies under the Companies Act 1981 of Bermuda,
     such as may be required under state securities laws and such as have been
     disclosed or are contemplated in the Acquisition Agreement.

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

        (23) Insurance Laws.  Each of the Guarantor and its insurance
             --------------
     subsidiaries (including insurance holding companies) is duly registered,
     licensed or admitted as an insurer or an insurance holding company (as
     applicable) in each jurisdiction where it is required to be so licensed or
     admitted to conduct its business as presently conducted, except where the
     failure to be so registered, licensed or admitted would not reasonably be
     expected to result in a Material Adverse Change; each of the Guarantor and
     its insurance subsidiaries (including insurance holding companies) is in
     compliance with all applicable insurance statutes and regulations and has
     filed all reports, documents or other information required to be filed
     under such statutes and regulations, except where the failure to comply or
     file would not reasonably be expected to result in a Material Adverse
     Change.

                                       10
<PAGE>

        (24) Governmental Authorization.   Except as set forth in the
             --------------------------
     Registration Statement and the Prospectus, no authorization, approval or
     consent of any governmental authority or agency is required (other than any
     license as an insurer or insurance holding company and other than those
     which have already been obtained) under the laws of any jurisdiction in
     which the Guarantor or any of its subsidiaries (including the Company)
     conduct their respective businesses in connection with the ownership,
     directly or indirectly, by the Guarantor of equity interests in any
     subsidiary (including the Company) or the repatriation of any amount from
     or to the Guarantor or any of its subsidiaries (including the Company),
     except to the extent that the failure to obtain such authorization,
     approval or consent would not reasonably be expected to result in a
     Material Adverse Change.

        (25) Commodity Exchange Act.  The Underwritten Securities, upon
             ----------------------
     issuance, will be excluded or exempted under, or beyond the purview of, the
     Commodity Exchange Act, as amended (the "Commodity Exchange Act"), and the
     rules and regulations of the Commodity Futures Trading Commission under the
     Commodity Exchange Act (the "Commodity Exchange Act Regulations").

        (26) Investment Company Act.  The Company and the Guarantor are not, and
             ----------------------
     upon the issuance and sale of the Underwritten Securities as herein
     contemplated and the application of the net proceeds therefrom as described
     in the Prospectus they will not be, an "investment company" within the
     meaning of the Investment Company Act of 1940, as amended (the "1940 Act").

  (b) Officers' Certificates.  Any certificate signed by any officer of the
Company, the Guarantor or any of their respective subsidiaries and delivered to
the Representative(s) or to counsel for the Underwriters in connection with the
offering of the Underwritten Securities shall be deemed a representation and
warranty by the Company, the Guarantor or such subsidiary, as the case may be,
to each Underwriter as to the matters covered thereby on the date of such
certificate and, unless subsequently amended or supplemented, at each
Representation Date subsequent thereto.

  SECTION 2.   Sale and Delivery to Underwriters; Closing.
               ------------------------------------------

  (a) Underwritten Securities.  The several commitments of the Underwriters to
purchase the Underwritten Securities pursuant to the applicable Terms Agreement
shall be deemed to have been made on the basis of the representations,
warranties and agreements herein contained and shall be subject to the terms and
conditions herein set forth.

  (b) Payment.  Payment of the purchase price for, and delivery of, the
Underwritten Securities shall be made at the offices of Brown & Wood llp, One

time) on the third (fourth, if the pricing occurs after 4:30 P.M. (Eastern time)
on any given day) business day after the date of the applicable Terms Agreement
(unless postponed in accordance with the provisions of Section 10 hereof), or
such other time not later than ten business days after such date as shall be
agreed upon by the Representative(s) and the Company (such time and date of
payment and delivery being herein called "Closing Time").

                                       11
<PAGE>

  Payment shall be made to the Company by wire transfer of immediately
available funds to a bank account designated by the Company, against delivery to
the Representative(s) for the respective accounts of the Underwriters of the
Underwritten Securities to be purchased by them.  It is understood that each
Underwriter has authorized the Representative(s), for its account, to accept
delivery of, receipt for, and make payment of the purchase price for, the
Underwritten Securities which it has severally agreed to purchase.  Any
Representative, individually and not as representative of the Underwriters, may
(but shall not be obligated to) make payment of the purchase price for the
Underwritten Securities to be purchased by any Underwriter whose funds have not
been received by the Closing Time, but such payment shall not relieve such
Underwriter from its obligations hereunder.

  (c) Denominations; Registration.  If the Underwritten Securities are issued
other than in book-entry form, certificates for the Underwritten Securities
shall be in such denominations and registered in such names as the
Representative(s) may request in writing at least one full business day prior to

               ------------------------------------------
Guarantor covenant with the Representative(s) and with each Underwriter
participating in the offering of Underwritten Securities, as follows:

  (a) Compliance with Securities Regulations and Commission Requests.  The
Company and the Guarantor, subject to Section 3(b), will comply with the
requirements of Rule 430A of the 1933 Act Regulations and/or Rule 434 of the
1933 Act Regulations, if and as applicable, and they will notify the
Representative(s) immediately, and confirm the notice in writing, of (i) the
effectiveness of any post-effective amendment to the Registration Statement or
the filing of any supplement or amendment to the Prospectus, (ii) the receipt of
any comments from the Commission, (iii) any request by the Commission for any
amendment to the Registration Statement or any amendment or supplement to the
Prospectus or for additional information, and (iv) the issuance by the
Commission of any stop order suspending the effectiveness of the Registration
Statement or of any order preventing or suspending the use of any preliminary
prospectus, or of the suspension of the qualification of the Underwritten
Securities for offering or sale in any jurisdiction, or of the initiation or
threatening of any proceedings for any of such purposes.  The Company and the
Guarantor will promptly effect the filings necessary pursuant to Rule 424 and
will take such steps as they deem necessary to ascertain promptly whether the
Prospectus transmitted for filing under Rule 424 was received for filing by the
Commission and, in the event that it was not, they will promptly file the
Prospectus.  The Company and the Guarantor will make every reasonable effort to
prevent the issuance of any stop order and, if any stop order is issued, to
obtain the lifting thereof at the earliest possible moment.

  (b) Filing of Amendments.  The Company and the Guarantor will give the
Representative(s) notice of their intention to file or prepare any amendment to
the Registration Statement (including any filing under Rule 462(b) of the 1933
Act Regulations), any Term Sheet or any amendment, supplement or revision to
either the prospectus included in the Registration Statement at the time it
became effective or to the Prospectus, whether pursuant to the 1933 Act,

                                       12
<PAGE>

the 1934 Act or otherwise, will furnish the Representative(s) with copies of any
such documents a reasonable amount of time prior to such proposed filing or use,
as the case may be, and will give the Representative(s) a reasonable opportunity
to comment on any such document prior to such proposed filing or use, as the
case may be.

  (c) Delivery of Registration Statements.   The Company and the Guarantor have
furnished or will deliver to the Representative(s) and counsel for the
Underwriters, without charge, signed copies of the Registration Statement as
originally filed and of each amendment thereto (including exhibits filed
therewith or incorporated by reference therein and documents incorporated or
deemed to be incorporated by reference therein) and signed copies of all
consents and certificates of experts, and will also deliver to the
Representative(s), without charge, a conformed copy of the Registration
Statement as originally filed and of each amendment thereto (without exhibits)
for each of the Underwriters.  The Registration Statement and each amendment
thereto furnished to the Underwriters will be identical to any electronically
transmitted copies thereof filed with the Commission pursuant to EDGAR, except
to the extent permitted by Regulation S-T.

  (d) Delivery of Prospectuses.  The Company and the Guarantor will deliver to
each Underwriter, without charge, as many copies of each preliminary prospectus
as such Underwriter may reasonably request, and the Company and the Guarantor
hereby consent to the use of such copies for purposes permitted by the 1933 Act.
The Company and the Guarantor will furnish to each Underwriter, without charge,
during the period when the Prospectus is required to be delivered under the 1933
Act or the 1934 Act, such number of copies of the Prospectus as such Underwriter
may reasonably request.  The Prospectus and any amendments or supplements
thereto furnished to the Underwriters will be identical to any electronically
transmitted copies thereof filed with the Commission pursuant to EDGAR, except
to the extent permitted by Regulation S-T.

  (e) Continued Compliance with Securities Laws.  The Company and the Guarantor
will comply with the 1933 Act and the 1933 Act Regulations and the 1934 Act and
the 1934 Act Regulations so as to permit the completion of the distribution of
the Underwritten Securities as contemplated in this Underwriting Agreement and
the applicable Terms Agreement and in the Registration Statement and the
Prospectus.  If at any time when the Prospectus is required by the 1933 Act or
the 1934 Act to be delivered in connection with sales of the Underwritten
Securities, any event shall occur or condition shall exist as a result of which
it is necessary, in the opinion of counsel for the Underwriters or for the
Company and the Guarantor, to amend the Registration Statement in order that the
Registration Statement will not 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 or to amend or supplement the
Prospectus in order that the Prospectus will not include an untrue statement of
a material fact or omit to state a material fact necessary in order to make the
statements therein not misleading in the light of the circumstances existing at
the time it is delivered to a purchaser, or if it shall be necessary, in the
opinion of such counsel, at any such time to amend the Registration Statement or
amend or supplement the Prospectus in order to comply with the requirements of
the 1933 Act or the 1933 Act Regulations, the Company and the Guarantor will
promptly prepare and file with the Commission, subject to Section 3(b), such
amendment or supplement as may be necessary to correct such statement or
omission or to make the Registration Statement or the Prospectus

                                       13
<PAGE>

comply with such requirements, and the Company and the Guarantor will furnish to
the Underwriters, without charge, such number of copies of such amendment or
supplement as the Underwriters may reasonably request.

  (f) Blue Sky Qualifications.  The Company and the Guarantor will use their
best efforts, in cooperation with the Underwriters, to qualify the Underwritten
Securities for offering and sale under the applicable securities laws of such
states and other jurisdictions (domestic or foreign) as the Representative(s)
may designate and to maintain such qualifications in effect for a period of not
less than one year from the date of the applicable Terms Agreement; provided,
however, that the Company and the Guarantor shall not be obligated to file any
general consent to service of process or to qualify as a foreign corporation or
as a dealer in securities in any jurisdiction in which they are not so qualified
or to subject themselves to taxation in respect of doing business in any
jurisdiction in which they are not otherwise so subject.  In each jurisdiction
in which the Underwritten Securities have been so qualified, the Company and the
Guarantor will file such statements and reports as may be required by the laws
of such jurisdiction to continue such qualification in effect for a period of
not less than one year from the date of such Terms Agreement.

  (g) Earnings Statement.  The Guarantor and, to the extent separately required
pursuant to Rule 158 under the 1933 Act, the Company will timely file such
reports pursuant to the 1934 Act as are necessary in order to make generally
available to its securityholders as soon as practicable an earnings statement
for the purposes of, and to provide the benefits contemplated by, the last
paragraph of Section 11(a) of the 1933 Act.

  (h) Use of Proceeds.  The Company will use the net proceeds received by it
from the sale of the Underwritten Securities in the manner specified in the
Prospectus under "Use of Proceeds".

  (i) Listing.  The Company and the Guarantor will use their best efforts to
effect the listing of the Underwritten Securities, prior to the Closing Time, on
any national securities exchange or quotation system if and as specified in the
applicable Terms Agreement.

  (j) Restriction on Sale of Debt Securities.  Between the date of the
applicable Terms Agreement and the Closing Time or such other date specified in
such Terms Agreement, neither the Company nor the Guarantor will, without the
prior written consent of the Representative(s), directly or indirectly, issue,
sell, offer or contract to sell, grant any option for the sale of, or otherwise
dispose of, the debt securities specified in such Terms Agreement.

  (k) Reporting Requirements.  The Guarantor, during the period when the
Prospectus is required to be delivered under the 1933 Act or the 1934 Act, will
file all documents required to be filed with the Commission pursuant to the 1934
Act within the time periods required by the 1934 Act and the 1934 Act
Regulations.

  (l) Documentary, Stamp or Similar Issue Taxes.  The Company and the Guarantor
will jointly and severally indemnify and hold harmless the Underwriters against
any documentary, stamp or similar issue tax, including any interest and
penalties, on the creation, issue and sale of the Underwritten Securities and on
the execution and delivery of this Underwriting Agreement or

                                       14
<PAGE>

the applicable Terms Agreement. All payments to be made by the Company or the
Guarantor hereunder shall be made without withholding or deduction for or on
account of any present or future taxes, duties or governmental charges
whatsoever unless the Company or the Guarantor is compelled by law to deduct or
withhold such taxes, duties or charges. In that event, the Company or the
Guarantor shall pay such additional amounts as may be necessary in order that
the net amounts received after such withholding or deduction shall equal the
amounts that would have been received if no withholding or deduction had been
made.

  SECTION 4.   Payment of Expenses.
               -------------------

  (a) Expenses.   The Company and the Guarantor will pay all expenses incident
to the performance of their obligations under this Underwriting Agreement or the
applicable Terms Agreement, including (i) the preparation, printing and filing

Agreement, any Agreement among Underwriters, the Indentures, and such other
documents as may be required in connection with the offering, purchase, sale,
issuance or delivery of the Underwritten Securities, (iii) the preparation,

by the Representative(s) in accordance with the provisions of Section 5 or

party except as provided in Section 4 and except that Sections 1, 6, 7 and 8
shall survive any such termination and remain in full force and effect.

  SECTION 6.   Indemnification.
               ---------------

  (a) Indemnification of Underwriters.  The Company and the Guarantor agree to
jointly and severally indemnify and hold harmless each Underwriter and each
person, if any, who controls any Underwriter within the meaning of Section 15 of
the 1933 Act or Section 20 of the 1934 Act as follows:

          (1)  against any and all loss, liability, claim, damage and expense
     whatsoever, as incurred, arising out of any untrue statement or alleged
     untrue statement of a material fact contained in the Registration Statement
     (or any amendment thereto), including the Rule 430A Information and the
     Rule 434 Information deemed to be a part thereof, if applicable, or the
     omission or alleged omission therefrom of a material fact required to be
     stated therein or necessary to make the statements therein not misleading
     or arising out of any untrue statement or alleged untrue statement of a
     material fact included in any preliminary prospectus or the Prospectus (or
     any amendment or supplement thereto), or the omission or alleged omission
     therefrom of a material fact necessary in order to make the statements
     therein, in the light of the circumstances under which they were made, not
     misleading;

          (2)  against any and all loss, liability, claim, damage and expense
     whatsoever, as incurred, to the extent of the aggregate amount paid in
     settlement of any litigation, or any

                                       18
<PAGE>

     investigation or proceeding by any governmental agency or body, commenced
     or threatened, or any claim whatsoever based upon any such untrue statement
     or omission, or any such alleged untrue statement or omission; provided
     that (subject to Section 6(d) below) any such settlement is effected with
     the written consent of the Company and the Guarantor; and

          (3)  against any and all expense whatsoever, as incurred (including
     the fees and disbursements of counsel chosen by the Representative(s)),
     reasonably incurred in investigating, preparing or defending against any
     litigation, or any investigation or proceeding by any governmental agency
     or body, commenced or threatened, or any claim whatsoever based upon any
     such untrue statement or omission, or any such alleged untrue statement or
     omission, to the extent that any such expense is not paid under (1) or (2)
     above;

provided, however, that this indemnity agreement shall not apply to any loss,
- --------  -------
liability, claim, damage or expense to the extent arising out of any untrue
statement or omission or alleged untrue statement or omission made in reliance
upon and in conformity with written information furnished to the Company or the
Guarantor by any Underwriter through the Representative(s) expressly for use in
the Registration Statement (or any amendment thereto), including the Rule 430A
Information and the Rule 434 Information deemed to be a part thereof, if
applicable, or any preliminary prospectus or the Prospectus (or any amendment or
supplement thereto).

  (b) Indemnification of Company, Guarantor, Directors and Officers.  Each
Underwriter severally agrees to indemnify and hold harmless the Company, the
Guarantor, their respective directors, each of their respective officers who
signed the Registration Statement, and each person, if any, who controls the
Company or the Guarantor within the meaning of Section 15 of the 1933 Act or
Section 20 of the 1934 Act against any and all loss, liability, claim, damage
and expense described in the indemnity contained in subsection (a) of this
Section, as incurred, but only with respect to untrue statements or omissions,
or alleged untrue statements or omissions, made in the Registration Statement
(or any amendment thereto), including the Rule 430A Information and the Rule 434
Information deemed to be a part thereof, if applicable, or any preliminary
prospectus or the Prospectus (or any amendment or supplement thereto) in
reliance upon and in conformity with written information furnished to the
Company or the Guarantor by such Underwriter through the Representative(s)
expressly for use in the Registration Statement (or any amendment thereto) or
such preliminary prospectus or the Prospectus (or any amendment or supplement
thereto).

  (c) Actions against Parties; Notification.  Each indemnified party shall give
notice as promptly as reasonably practicable to each indemnifying party of any
action commenced against it in respect of which indemnity may be sought
hereunder, but failure to so notify an indemnifying party shall not relieve such
indemnifying party from any liability hereunder to the extent it is not
materially prejudiced as a result thereof and in any event shall not relieve it
from any liability which it may have otherwise than on account of this indemnity
agreement.  In the case of parties indemnified pursuant to Section 6(a) above,
counsel to the indemnified parties shall be selected by the Representative(s),
and, in the case of parties indemnified pursuant to Section 6(b) above, counsel
to the indemnified parties shall be selected by the Guarantor.  An indemnifying
party may participate at its own expense in the defense of any such action;

                                       19
<PAGE>

provided, however, that counsel to the indemnifying party shall not (except with
the consent of the indemnified party) also be counsel to the indemnified party.
In no event shall the indemnifying parties be liable for fees and expenses of
more than one counsel (in addition to any local counsel) separate from their own
counsel for all indemnified parties in connection with any one action or
separate but similar or related actions in the same jurisdiction arising out of
the same general allegations or circumstances.  No indemnifying party shall,
without the prior written consent of the indemnified parties, settle or
compromise or consent to the entry of any judgment with respect to any
litigation, or any investigation or proceeding by any governmental agency or
body, commenced or threatened, or any claim whatsoever in respect of which
indemnification or contribution could be sought under this Section 6 or Section
7 hereof (whether or not the indemnified parties are actual or potential parties
thereto), unless such settlement, compromise or consent (i) includes an
unconditional release of each indemnified party from all liability arising out
of such litigation, investigation, proceeding or claim and (ii) does not include
a statement as to or an admission of fault, culpability or a failure to act by
or on behalf of any indemnified party.

  (d) Settlement without Consent if Failure to Reimburse.  If at any time an
indemnified party shall have requested an indemnifying party to reimburse the
indemnified party for fees and expenses of counsel, such indemnifying party
agrees that it shall be liable for any settlement of the nature contemplated by
Section 6(a)(2) effected without its written consent if (i) such settlement is
entered into more than 45 days after receipt by such indemnifying party of the
aforesaid request, (ii) such indemnifying party shall have received notice of
the terms of such settlement at least 30 days prior to such settlement being
entered into and (iii) such indemnifying party shall not have reimbursed such
indemnified party in accordance with such request prior to the date of such
settlement.

  SECTION 7.   Contribution.  If the indemnification provided for in Section 6
               ------------
hereof is for any reason unavailable to or insufficient to hold harmless an
indemnified party in respect of any losses, liabilities, claims, damages or
expenses referred to therein, then each indemnifying party shall contribute to
the aggregate amount of such losses, liabilities, claims, damages and expenses
incurred by such indemnified party, as incurred, (i) in such proportion as is
appropriate to reflect the relative benefits received by the Company and the
Guarantor, on the one hand, and the Underwriters, on the other hand, from the
offering of the Underwritten Securities pursuant to the applicable Terms
Agreement or (ii) if the allocation provided by clause (i) is not permitted by
applicable law, in such proportion as is appropriate to reflect not only the
relative benefits referred to in clause (i) above but also the relative fault of
the Company and the Guarantor, on the one hand, and the Underwriters, on the
other hand, in connection with the statements or omissions which resulted in
such losses, liabilities, claims, damages or expenses, as well as any other
relevant equitable considerations.

  The relative benefits received by the Company and the Guarantor, on the one
hand, and the Underwriters, on the other hand, in connection with the offering
of the Underwritten Securities pursuant to the applicable Terms Agreement shall
be deemed to be in the same respective proportions as the total net proceeds
from the offering of such Underwritten Securities (before deducting expenses)
received by the Company and the total underwriting discount received by the
Underwriters, in each case as set forth on the cover of the Prospectus, or, if
Rule

                                       20
<PAGE>

434 is used, the corresponding location on the Term Sheet bear to the aggregate
initial public offering price of such Underwritten Securities as set forth on
such cover.

     The relative fault of the Company and the Guarantor, on the one hand, and
the Underwriters, on the other hand, shall be determined by reference to, among
other things, whether any such untrue or alleged untrue statement of a material
fact or omission or alleged omission to state a material fact relates to
information supplied by the Company or the Guarantor or by the Underwriters and
the parties' relative intent, knowledge, access to information and opportunity
to correct or prevent such statement or omission.

     The Company, the Guarantor and the Underwriters agree that it would not be
just and equitable if contribution pursuant to this Section 7 were determined by
pro rata allocation (even if the Underwriters were treated as one entity for
such purpose) or by any other method of allocation which does not take account
of the equitable considerations referred to above in this Section 7.  The
aggregate amount of losses, liabilities, claims, damages and expenses incurred
by an indemnified party and referred to above in this Section 7 shall be deemed
to include any legal or other expenses reasonably incurred by such indemnified
party in investigating, preparing or defending against any litigation, or any
investigation or proceeding by any governmental agency or body, commenced or
threatened, or any claim whatsoever based upon any such untrue or alleged untrue
statement or omission or alleged omission.

     Notwithstanding the provisions of this Section 7, no Underwriter shall be
required to contribute any amount in excess of the amount by which the total
price at which the Underwritten Securities underwritten by it and distributed to
the public were offered to the public exceeds the amount of any damages which
such Underwriter has otherwise been required to pay by reason of any such untrue
or alleged untrue statement or omission or alleged omission.

     No person guilty of fraudulent misrepresentation (within the meaning of
Section 11(f) of the 1933 Act) shall be entitled to contribution from any person
who was not guilty of such fraudulent misrepresentation.

     For purposes of this Section 7, each person, if any, who controls an
Underwriter within the meaning of Section 15 of the 1933 Act or Section 20 of
the 1934 Act shall have the same rights to contribution as such Underwriter, and
each director of the Company and the Guarantor, each officer of the Company and
the Guarantor who signed the Registration Statement, and each person, if any,
who controls the Company or the Guarantor within the meaning of Section 15 of
the 1933 Act or Section 20 of the 1934 Act shall have the same rights to
contribution as the Company and the Guarantor.  The Underwriters' respective
obligations to contribute pursuant to this Section 7 are several in proportion
to the aggregate principal amount of Initial Underwritten Securities set forth
opposite their respective names in the applicable Terms Agreement, and not
joint.

     SECTION 8.   Representations, Warranties and Agreements to Survive
                  -----------------------------------------------------
Delivery.  All representations, warranties and agreements contained in this
- --------
Underwriting Agreement or the applicable Terms Agreement or in certificates of
officers of the Company, the Guarantor or any of their respective subsidiaries
submitted pursuant hereto or thereto shall remain operative and in full force
and effect, regardless of any investigation made by or on behalf of any
Underwriter or

                                       21
<PAGE>

controlling person, or by or on behalf of the Company or the Guarantor, and
shall survive delivery of and payment for the Underwritten Securities.

  SECTION 9.   Termination.
               -----------

  (a) Terms Agreement.  The Representative(s) may terminate this Agreement and
the applicable Terms Agreement, by notice to the Company and the Guarantor, at
any time at or prior to the Closing Time, if (i) there has been, since the time
of execution of such Terms Agreement or since the respective dates as of which
information is given in the Prospectus, any material adverse change, or any
development or event involving a prospective material adverse change, in the
financial condition, business or results of operations of the Company and its
subsidiaries considered as one enterprise, whether or not arising in the
ordinary course of business, or (ii) there has been, since the time of execution
of such Terms Agreement or since the respective dates as of which information is
given in the Prospectus, any material adverse change, or any development or
event involving a prospective material adverse change, in the financial
condition, business or results of operations of the Guarantor and its
subsidiaries considered as one enterprise, whether or not arising in the
ordinary course of business, or (iii) there has occurred any material adverse
change in the financial markets in the United States or any outbreak of
hostilities or escalation thereof or other calamity or crisis or any change or
development involving a prospective change in national or international
political, financial or economic conditions, in each case referred to in this
clause (iii), the effect of which is such as to make it, in the judgment of the
Representative(s), impracticable to market the Underwritten Securities or to
enforce contracts for the sale of the Underwritten Securities, or (iv) trading
in any securities of the Company or the Guarantor has been suspended or
materially limited by the Commission or the New York Stock Exchange, or if
trading generally on the New York Stock Exchange or the American Stock Exchange
or in the Nasdaq National Market has been suspended or materially limited, or
minimum or maximum prices for trading have been fixed, or maximum ranges for
prices have been required, by either of said exchanges or by such system or by
order of the Commission, the NASD or any other governmental authority, or (v) a
banking moratorium has been declared by either U.S. Federal, New York or Bermuda
authorities or, if the Underwritten Securities are denominated or payable in, or
indexed to, one or more foreign or composite currencies, by the relevant
authorities in the related foreign country or countries.

  (b) Liabilities.  If this Underwriting Agreement or the applicable Terms
Agreement is terminated pursuant to this Section 9, such termination shall be
without liability of any party to any other party except as provided in Section
4 hereof, and provided further that Sections 1, 6, 7 and 8 shall survive such
termination and remain in full force and effect.

                                       22
<PAGE>

  SECTION 10.  Default by One or More of the Underwriters.  If one or more of
               ------------------------------------------
the Underwriters shall fail at the Closing Time to purchase the Underwritten
Securities which it or they are obligated to purchase under the applicable Terms
Agreement (the "Defaulted Securities"), then the Representative(s) shall have
the right, within 24 hours thereafter, to make arrangements for one or more of
the non-defaulting Underwriters, or any other underwriters, to purchase all, but
not less than all, of the Defaulted Securities in such amounts as may be agreed
upon and upon the terms herein set forth; if, however, the Representative(s)
shall not have completed such arrangements within such 24-hour period, then:

          (a)  if the number or aggregate principal amount, as the case may be,
     of Defaulted Securities does not exceed 10% of the number or aggregate
     principal amount, as the case may be, of Underwritten Securities to be
     purchased on such date pursuant to such Terms Agreement, the non-defaulting
     Underwriters shall be obligated, severally and not jointly, to purchase the
     full amount thereof in the proportions that their respective underwriting
     obligations under such Terms Agreement bear to the underwriting obligations
     of all non-defaulting Underwriters, or

          (b)  if the number or aggregate principal amount, as the case may be,
     of Defaulted Securities exceeds 10% of the number or aggregate principal
     amount, as the case may be, of Underwritten Securities to be purchased on
     such date pursuant to such Terms Agreement, such Terms Agreement shall
     terminate without liability on the part of any non-defaulting Underwriter.

  No action taken pursuant to this Section 10 shall relieve any defaulting
Underwriter from liability in respect of its default.

  In the event of any such default which does not result in a termination of
the applicable Terms Agreement, either the Representative(s) or the Company
shall have the right to postpone the Closing Time for a period not exceeding
seven days in order to effect any required changes in the Registration Statement
or the Prospectus or in any other documents or arrangements.

  SECTION 11.  Notices.  All notices and other communications hereunder shall be
               -------
in writing and shall be deemed to have been duly given if mailed or transmitted
by any standard form of telecommunication.  Notices to the Underwriters shall be
directed to the Representative(s) at the address specified in the applicable
Terms Agreement; notices to the Company shall be directed to it at 1601 Chestnut
Street, P.O. Box 41484, Philadelphia, PA  19101-1481, attention of General
Counsel; and notices to the Guarantor shall be directed to it at The ACE
Building, 30 Woodbourne Avenue, Hamilton HM 08 Bermuda, attention of General

  SECTION 12.  Parties.   This Underwriting Agreement and the applicable Terms
               -------
Agreement shall each inure to the benefit of and be binding upon the Company and
the Guarantor and, upon execution of such Terms Agreement, any Underwriters
named therein and their respective successors.  Nothing expressed or mentioned
in this Underwriting Agreement or such Terms Agreement is intended or shall be
construed to give any person, firm or corporation, other than the Underwriters,
the Company, the Guarantor and their respective successors and the controlling
persons and officers and directors referred to in Sections 6 and 7 and their
heirs and

                                       23
<PAGE>

legal representatives, any legal or equitable right, remedy or claim under or in
respect of this Underwriting Agreement or such Terms Agreement or any provision
herein or therein contained. This Underwriting Agreement and such Terms
Agreement and all conditions and provisions hereof and thereof are intended to
be for the sole and exclusive benefit of the parties hereto and thereto and
their respective successors, and said controlling persons and officers and
directors and their heirs and legal representatives, and for the benefit of no
other person, firm or corporation. No purchaser of Underwritten Securities from
any Underwriter shall be deemed to be a successor by reason merely of such
purchase.

  SECTION 13.  Consent to Jurisdiction; Miscellaneous.  Each of the parties
               --------------------------------------
hereto hereby expressly and irrevocably submits to the non-exclusive
jurisdiction of any competent court in the place of its domicile and any United
States Federal or New York State court sitting in the Borough of Manhattan in
The City of New York in any action, suit or proceeding arising out of or
relating to this Underwriting Agreement or the applicable Terms Agreement or the
transactions contemplated hereby or thereby to the extent that such court has
subject matter jurisdiction over the controversy, and expressly and irrevocably
waives, to the extent permitted under applicable law, any immunity from the
jurisdiction thereof and any claim or defense in such action, suit or proceeding
based on a claim of improper venue, forum non conveniens or any similar basis to
                                    ----- --- ----------
which it might otherwise be entitled in any such action, suit or proceeding.
Each of the Company and the Guarantor irrevocably appoints CT Corporation as its
authorized agent in the Borough of Manhattan in The City of New York upon which
process may be served in any such action, suit or proceeding, and agrees that
service of process upon such agent, and written notice of said service to the
Company or the Guarantor by the person serving the same to the address provided
in Section 11, shall be deemed in every respect effective service of process
upon the Company or the Guarantor, as the case may be, in any such action, suit
or proceeding.  Each of the Company and the Guarantor further agrees to take any
and all action as may be necessary to maintain such designation and appointment
of such agent in full force and effect for a period of seven years from the date
of this Underwriting Agreement.

  SECTION 14.  WAIVER OF IMMUNITIES.   To the extent that the Company or the
               --------------------
Guarantor or any of their respective properties, assets or revenues may have or
may hereafter become entitled to, or have attributed to them, any right of
immunity, on the grounds of sovereignty, from any legal action, suit or
proceeding, from set-off or counterclaim, from the jurisdiction of any court,
from service of process, from attachment upon or prior to judgment, or from

               FORM OF OPINION OF MAPLES AND CALDER, GUARANTOR'S
                    CAYMAN ISLANDS COUNSEL, TO BE DELIVERED
                            PURSUANT TO SECTION 5(b)

         (i) The Guarantor has been duly incorporated and is validly existing
     and in good standing as an exempted company, under the laws of the Cayman
     Islands, and has the corporate power and corporate authority to own, lease
     and operate its property, and to conduct its business, as described in the
     Registration Statement and the Prospectus, and to enter into and perform
     its obligations under, or as contemplated under, the Underwriting Agreement
     and the applicable Terms Agreement.

         (ii) The authorized share capital of the Guarantor, as set out in its
     Memorandum and Articles of Association, conforms as to legal matters to the
     description thereof contained in the Registration Statement and the
     Prospectus.  All of the Guarantor's Ordinary Shares have been duly and
     validly authorized and issued by the Guarantor and are registered in the
     books of the Guarantor as fully paid.  On the basis that the contractual
     subscription price of all such Ordinary Shares is fully paid in cash (or
     equivalent consideration approved by the Directors), such Ordinary Shares
     issued may properly be credited as fully paid under Cayman Islands law and,
     as the Guarantor has been established on the basis that the liability of
     its shareholders is limited to the amount, if any, unpaid on their Ordinary
     Shares (see Clause 5 of the Memorandum and Articles of Association), there
     is no rule of Cayman Islands law that would impose any further liability on
     persons holding Ordinary Shares in the Guarantor, merely by reason of such
     shareholding.  So far as Cayman Islands law is concerned, the registered
     holders have good and valid title to their respective Ordinary Shares on
     the assumption that they have not entered into any liens, encumbrances,
     equities or claims which could give rise to any equitable interest on the
     part of any third party in respect of such Ordinary Shares.  The holders of
     Ordinary Shares are not subject to any pre-emptive rights under the laws of
     the Cayman Islands or the Guarantor's Memorandum and Articles of
     Association.

         (iii)  The Underwriting Agreement and the applicable Terms Agreement
     have been duly authorized, executed and delivered by the Guarantor.

         (iv) The Guarantee has been duly authorized, executed and delivered by
     the Guarantor for issuance and sale pursuant to the Underwriting Agreement
     and the applicable Terms Agreement.

         (v) Each applicable Indenture has been duly authorized, executed and
     delivered by the Guarantor.

         (vi) The execution and delivery by the Guarantor of, and the
     performance by the Guarantor of its obligations under, the Underwriting
     Agreement and the applicable Terms Agreement and each applicable Indenture
     and any other agreement or instrument entered into or issued or to be
     entered into or issued by the Guarantor in connection with the transactions
     contemplated by the Registration Statement and the Prospectus and the

                                      B-1
<PAGE>

     consummation by the Guarantor of the transactions contemplated by the
     Underwriting Agreement and such Terms Agreement do not and will not (A)
     violate any provision of the Memorandum and Articles of Association of the
     Guarantor; (B) contravene any provision of any law, public rule or
     regulation of the Cayman Islands applicable to the Guarantor; (C) to the
     best of such counsel's knowledge, contravene any existing published order
     or decree of the courts of the Cayman Islands by which the Guarantor is
     bound or by which its properties or assets may be affected; or (D) require
     any consent, approval or authorization or order of, or qualification with,
     any Cayman Islands governmental agency in connection with the offer and
     sale of the Underwritten Securities and the Guarantee.

         (vii)  To the best of such counsel's knowledge, but based only upon a
     search of the cause list at the offices of the Grand Courts of the Cayman
     Islands, there was no action, suit or proceeding to which the Guarantor or
     any of its subsidiaries is a party or to which the assets, properties or
     operations of the Guarantor or any of its subsidiaries is subject, before
     the courts of the Cayman Islands at the close of business on [specify a
     recent date].

         (viii)  All statements made in the Prospectus with regard to statutes,
     regulations, rules, treaties and other laws of the Cayman Islands
     (including, but not limited to, insurance, regulatory and tax matters and
     the Companies Law (1995 Revision) of the Cayman Islands) and enforcement of
     judgments in the Cayman Islands are accurate.

         (ix) Pursuant to the Underwriting Agreement, and to the extent that the
     laws of the Cayman Islands are relevant, the Guarantor has legally,
     validly, effectively and irrevocably submitted to the jurisdiction of the
     United States Federal and New York State courts sitting in the Borough of
     Manhattan in The City of New York, State of New York, and has legally,
     validly and effectively appointed CT Corporation System as the authorized
     agent of the Guarantor for the purposes described in Section 13 of the
     Underwriting Agreement assuming this to be the case as a matter of the
     applicable United States Federal and New York State laws.

         (x) The choice of the laws of the State of New York, United States of
     America as the governing law of the Underwriting Agreement is a valid and
     effective choice of law and in an action brought before a court of
     competent jurisdiction in the Cayman Islands, the laws of the State of New
     York would, to the extent specifically pleaded and proved as a fact by
     expert evidence, be recognized and applied by such court to all issues
     concerning the formal and essential validity of the Underwriting Agreement
     and the interpretation thereof, except that in any such action such court
     will apply those laws of the Cayman Islands as such court characterizes as
     procedural, and will not apply those laws of the State of New York as such
     court characterizes as procedural.

         (xi) Although there is no statutory enforcement in the Cayman Islands
     of a judgment obtained in New York, the courts of the Cayman Islands will
     recognize and enforce a foreign judgment of a court of competent
     jurisdiction, based on the principle that a judgment of a competent foreign
     court imposes upon the judgment debtor an obligation to pay the sum for
     which judgment has been given provided such judgment is

                                      B-2
<PAGE>

     final, for a liquidated sum, not in respect of taxes or a fine or penalty,
     and was not obtained in a manner and is not of a kind the enforcement of
     which is contrary to the public policy of the Cayman Islands. A Cayman
     Islands court may stay proceedings if concurrent proceedings are being
     brought elsewhere. For the purposes of enforcement of a judgment granted
     against the Guarantor in respect of the Underwriting Agreement, a court in
     the Cayman Islands would recognize the jurisdiction of the applicable
     federal or state court to the jurisdiction of which the Guarantor has
     submitted rendering such judgment if service of process on the Guarantor is
     effected pursuant to and in accordance with the provisions of the
     Underwriting Agreement.

         (xii)  On the basis that the Guarantor carries on its business as set
     forth in the Prospectus, there is no requirement that it be licensed under
     the Insurance Law, 1979, as amended of the Cayman Islands.

     [In rendering such opinion, such counsel may rely (A) as to matters
involving the application of laws other than the laws of the Cayman Islands, to
the extent such counsel deems proper and specified in such opinion, upon the
opinion of other counsel whom such counsel believes to be reliable (which
opinion shall be dated and furnished to the Representative(s) at the Closing
Time, shall be satisfactory in form and substance to counsel for the
Underwriters and shall expressly state that the Underwriters may rely on such
opinion as if it were addressed to them), provided that such counsel shall state
in their opinion that they believe that they and the Underwriters are justified
in relying upon such opinion, and (B) as to matters of fact (but not as to legal
conclusions), to the extent such counsel deems proper, on certificates of
responsible officers of the Guarantor, its subsidiaries and public officials.]

             FORM OF OPINION OF CONYERS DILL & PEARMAN, GUARANTOR'S
                        BERMUDA COUNSEL, TO BE DELIVERED
                            PURSUANT TO SECTION 5(b)

         (i) Each of ACE Bermuda Insurance Ltd. and Tempest Reinsurance Company
     Limited (collectively, the "Bermuda Insurance Subsidiaries") (A) is validly
     existing under the laws of Bermuda as a company with limited liability and
     is in good standing under the laws of Bermuda (meaning that such company
     has not failed to make any filing with any Bermuda government authority or
     to pay any Bermuda government fee or tax, the failure of which would make
     such company immediately liable to be struck off the Register of Companies
     and thereby cease to exist under the laws of Bermuda) and (B) the corporate
     objects and powers contained in the Memorandum of Association of each of
     the Bermuda Insurance Subsidiaries are sufficient to allow them to carry on
     their business and to own, lease and operate its properties as both are
     described in the Prospectus.

         (ii) Based solely upon a certified copy of the Register of Members for
     each of the Bermuda Insurance Subsidiaries, and without further inquiry,
     (a) all of the issued shares in the share capital of each of the Bermuda
     Insurance Subsidiaries have been duly and validly authorized and issued and
     are fully paid and nonassessable (meaning that, subject to the common law
     doctrine of "piercing the corporate veil" and to any agreement to the
     contrary between the registered holders and such Bermuda Insurance
     Subsidiary, no further sums are required to be paid by the holders thereof
     in connection with the issue of such shares); and (b) the Guarantor is the
     registered holder of all the issued shares of each of the Bermuda Insurance
     Subsidiaries (except for a de minimis number of shares necessary to comply
     with applicable law); and (c) based solely upon the Register of Charges,
     and without further inquiry, there are no registered liens, encumbrances,
     equities or claims in the Register of Charges in respect of those shares.

         (iii)  Each of the Bermuda Insurance Subsidiaries is duly registered as
     an insurer under the Insurance Act of 1978 (Bermuda) and the regulations
     promulgated thereunder (together, the "Insurance Act") and as so
     registered, each Bermuda Insurance Subsidiary may conduct that insurance
     business which it is described in the Prospectus as carrying on; and, based
     solely on the Certificates of Compliance and without independent inquiry,
     each of the Bermuda Insurance Subsidiaries has filed with the appropriate
     Bermuda governmental authority all reports, documents or other information
     required to be filed under the Insurance Act.

         (iv) The execution and delivery by the Guarantor of, and the
     performance by the Guarantor of its obligations under, the Underwriting
     Agreement and the applicable Terms Agreement and each applicable Indenture
     and any other agreement or instrument entered into or issued or to be
     entered into or issued by the Guarantor in connection with the transactions
     contemplated by the Registration Statement and the Prospectus and the
     consummation by the Guarantor of the transactions contemplated by the
     Underwriting Agreement and such Terms Agreement do not and will not (A)
     violate any provision of the Memorandum of Association or By-laws of each
     of the Bermuda Insurance

                                      C-1
<PAGE>

     Subsidiaries (B) contravene any provision of any of those laws, rules and
     regulations of Bermuda which, in such counsel's opinion, based upon such
     counsel's experience, are normally applicable to transactions of the type
     contemplated by the Underwriting Agreement and such Terms Agreement, except
     that such counsel need not express any opinion in this paragraph with
     respect to Bermuda securities laws; (C) based solely upon the Cause Book
     and without further inquiry, contravene any judgment, order or decree by
     the Bermuda Supreme Court against the Guarantor or any of the Bermuda
     Insurance Subsidiaries; (D) based solely upon the Register of Charges and
     without further inquiry, conflict with, result in any breach of or
     constitute a default (or an event which, with notice or lapse of time, or
     both, would constitute a default) under, or give rise to any right to
     accelerate the maturity or require the prepayment of any registered charge
     recorded in the Register of Charges against the Guarantor or any of the
     Bermuda Insurance Subsidiaries; or (E) require any consent, approval or
     authorization or order of, or qualification with any Bermuda governmental
     agency, except such as have been obtained under the applicable securities
     laws of Bermuda in connection with the offer and sale of the Underwritten
     Securities.

         (v) Based solely upon the Cause Book and without further inquiry, there
     is no action, suit or proceeding now pending before the Bermuda Supreme
     Court to which the Guarantor or any of its subsidiaries is a party or to
     which the assets, properties or operations of the Guarantor or any of its
     subsidiaries is subject.

         (vi) All statements (but excluding those statements forming a part of
     financial information or accounts) made in the Registration Statement and
     Prospectus with respect to statutes, regulations, rules, treaties and other
     laws of Bermuda (including, but not limited to, statements made with
     respect to the Insurance Act and Bermuda tax matters) fairly and accurately
     present the information set forth therein and such counsel's opinion as to
     such matters.

     [In rendering such opinion, such counsel may rely (A) as to matters
involving the application of laws other than the laws of Bermuda, to the extent
such counsel deems proper and specified in such opinion, upon the opinion of
other counsel whom such counsel believes to be reliable (which opinion shall be
dated and furnished to the Representative(s) at the Closing Time, shall be
satisfactory in form and substance to counsel for the Underwriters and shall
expressly state that the Underwriters may rely on such opinion as if it were
addressed to them), provided that such counsel shall state in their opinion that
they believe that they and the Underwriters are justified in relying upon such
opinion, and (B) as to matters of fact (but not as to legal conclusions), to the
extent such counsel deems proper, on certificates of responsible officers of the
Guarantor, its subsidiaries and public officials.]

                    FORM OF OPINION OF PETER N. MEAR, ESQ.,
                       GENERAL COUNSEL OF THE GUARANTOR,
                    TO BE DELIVERED PURSUANT TO SECTION 5(b)

         (i) The Guarantor is qualified to do business, and is in good standing,
     as a foreign corporation, under the laws of each jurisdiction in which the
     conduct of its business or its ownership or leasing of property requires
     such qualification, except to the extent that the failure to be so
     qualified or to be in good standing would not singly or in the aggregate
     result in a Material Adverse Change.

         (ii) Each of ACE Bermuda Insurance Ltd., Tempest Reinsurance Company
     Limited, ACE USA, Inc. and the Company is qualified to transact business
     and is in good standing (with respect to jurisdictions which recognize such
     concept) in each jurisdiction in which it owns or leases real property or
     in which the conduct of its business requires such qualification, except
     where the failure to be so qualified or to be in good standing (with
     respect to jurisdictions which recognize such concept) would not singly or
     in the aggregate result in a Material Adverse Change;

         (iii)  Except as set forth in the Registration Statement and the
     Prospectus, such counsel does not know of any outstanding (A) securities or
     obligations of the Guarantor convertible into or exchangeable for any
     shares of capital stock of the Guarantor or any of its subsidiaries; (B)
     rights, warrants or options to acquire or purchase from the Guarantor any
     shares of capital stock of the Guarantor or any such convertible or
     exchangeable securities or obligations; or (C) obligations or
     understandings of the Guarantor to issue or sell any shares of capital
     stock of the Guarantor or any of its subsidiaries, any such convertible or
     exchangeable securities or obligations, or any such warrants, rights or
     obligations.

         (iv) To the best of such counsel's knowledge, and other than as
     disclosed in the Prospectus, there are no threatened legal proceedings
     against the Guarantor or any of its subsidiaries which, if determined
     adversely to the Guarantor or such subsidiary, would result in a Material
     Adverse Change.

     [In rendering such opinion, such counsel may rely as to matters of fact
(but not as to legal conclusions), to the extent such counsel deems proper, on

                    FORM OF OPINION OF MAYER, BROWN & PLATT,
                 UNITED STATES COUNSEL FOR THE COMPANY AND THE

     the Company of the transactions contemplated by the Underwriting Agreement
     and such Terms Agreement do not and will not (A) contravene any provision
     of any United States federal or New York State law, rule or regulation, in

     contemplated by the Underwriting Agreement and such Terms Agreement
     ("United States Applicable Laws"), except that such counsel need not
     express any opinion in this paragraph with respect to state securities
     laws; (B) contravene any judgment, order or decree known to such counsel
     without independent inquiry of any United States federal or New York State

     subsidiaries is bound or by which their properties or assets may be
     affected; (C) conflict with, result in any breach of or constitute a
     default (or an event which, with notice or lapse of time, or both, would
     constitute a default) under, or give rise to any right to accelerate the
     maturity or require the prepayment of any indebtedness or the purchase of
     any capital stock under, or result in the creation or imposition of any
     lien, charge or encumbrance upon any properties or assets of the Company or
     any of its subsidiaries, pursuant to the terms of, any agreement or
     instrument filed as an exhibit to the Guarantor's Annual Report on Form 10-

     violations, defaults, accelerations, repayments, repurchases, liens,
     charges or encumbrances that would not singly or in the aggregate result in
     a Material Adverse Change; or (D) based upon such counsel's review of the
     United States Applicable Laws, require any consent, approval or
     authorization or order of, or qualification with, any United States federal
     or state governmental agency or authority or court, except such as have
     been obtained under the 1933 Act, the 1933 Act Regulations, the 1939 Act
     and the 1939 Act Regulations and such as may be required under state
     securities or blue sky laws or state insurance laws in connection with the
     offer and sale of the Underwritten Securities.

                                      E-1
<PAGE>

         (iii)  The Underwriting Agreement and the applicable Terms Agreement
     have been duly authorized, executed and delivered by the Company.

         (iv) The Underwritten Securities have been duly authorized, executed
     and delivered by the Company for issuance and sale pursuant to the
     Underwriting Agreement and the applicable Terms Agreement.

         (v) The Underwritten Securities, when issued and authenticated in the
     manner provided for in the applicable Indenture and delivered against
     payment of the consideration therefor specified in such Terms Agreement,
     will constitute valid and binding obligations of the Company, enforceable
     against the Company in accordance with their terms, except as the
     enforcement thereof may be limited by bankruptcy, insolvency (including,
     without limitation, all laws relating to fraudulent transfers),
     reorganization, moratorium or other similar laws affecting the enforcement
     of creditors' rights generally or by general equitable principles
     (regardless of whether enforcement is considered in a proceeding in equity
     or at law), and except further as enforcement thereof may be limited by
     requirements that a claim with respect to any Debt Securities payable in a
     foreign or corporate currency (or a foreign or composite currency judgment
     in respect of such claim) be converted into U.S. dollars at a rate of
     exchange prevailing on a date determined pursuant to applicable law or by
     governmental authority to limit, delay or prohibit the making of payments
     outside the United States.  The Underwritten Securities are in the form
     contemplated by, and each registered holder thereof is entitled to the
     benefits of, the [each] applicable Indenture.

         (vi) Assuming the Guarantee has been duly authorized by the Guarantor
     for issuance and sale pursuant to the Underwriting Agreement and the
     applicable Terms Agreement, the Guarantee, when duly executed in the manner
     contemplated in the Indenture and issued and delivered to the Underwriters
     in accordance with the provisions of the Underwriting Agreement, will
     constitute a legal, valid and binding obligation of the Guarantor
     enforceable against the Guarantor in accordance with its terms, except as
     the enforcement thereof may be limited by bankruptcy, insolvency,
     (including, without limitation, all laws relating to fraudulent transfers),
     reorganization, moratorium or other similar laws affecting the enforcement
     of creditors' rights generally or by general equitable principles
     (regardless of whether enforcement is considered in a proceeding in equity
     or at law).

         (vii)  The [each] applicable Indenture has been duly authorized,
     executed and delivered by the Company and the Guarantor and (assuming the
     Indenture has been duly authorized, executed and delivered by the Guarantor
     and the applicable Trustee), the [each] applicable Indenture constitutes a
     valid and binding agreement of the Company and the Guarantor, enforceable
     against the Company and the Guarantor in accordance with its terms, except
     as the enforcement thereof may be limited by bankruptcy, insolvency
     (including, without limitation, all laws relating to fraudulent transfers),
     reorganization, moratorium or other similar laws affecting the enforcement
     of creditors' rights generally or by general equitable principles
     (regardless of whether enforcement is considered in a proceeding in equity
     or at law).

                                      E-2

         (viii)  The Underwritten Securities, the Guarantee and the [each]
     applicable Indenture conform in all material respects to the statements
     relating thereto contained in the Prospectus and are in substantially the
     form filed or incorporated by reference, as the case may be, as an exhibit
     to the Registration Statement.

         (ix) Such counsel does not know, after inquiry of officers of the
     Company and the Guarantor and based solely on such inquiry, of any action,
     suit or proceeding before or by any United States federal or state
     government, governmental instrumentality or court now pending or threatened
     against or affecting the Guarantor or any of its subsidiaries (including
     the Company) or any of their respective assets or properties that is
     required to be described in the Registration Statement or the Prospectus
     and is not so described or of any contract or other document that is
     required to be described in the Registration Statement or the Prospectus,
     or to be filed as an exhibit to the Registration Statement, that is not
     described or filed, as required.

         (x) The statements in the Registration Statement and the Prospectus
     insofar as they are descriptions of contracts, agreements, instruments or
     the Company's Certificate of Incorporation or legal proceedings, or
     constitute statements or summaries of United States federal or New York
     State laws or legal conclusions with respect thereto, are accurate and
     present fairly the information required to be shown.

         (xi) The discussion of tax matters set forth under the heading "Certain
     Tax Consequences" in the Prospectus contains the relevant and material
     provisions of present United States tax law applicable to the Underwritten
     Securities and the Guarantee and the statements thereunder are true and
     correct (subject to the qualifications and assumptions set forth in such
     discussion) as of the Closing Date.

         (xii)  The Registration Statement (including any Rule 462(b)
     Registration Statement) and the Prospectus, excluding the documents
     incorporated by reference therein, and each amendment or supplement to the
     Registration Statement (including any Rule 462(b) Registration Statement)
     and Prospectus, excluding the documents incorporated by reference therein,
     as of their respective effective or issue dates (other than the financial
     statements and supporting schedules and other financial data included
     therein or omitted therefrom and each Trustee's Statement of Eligibility on
     Form T-1 (the "Form T-1s"), as to which such counsel need  express no
     opinion) complied as to form in all material respects with the requirements
     of the 1933 Act and the 1933 Act Regulations.

         (xiii)  The documents incorporated by reference in the Prospectus
     (other than the financial statements and supporting schedules and other
     financial data included therein or omitted therefrom, as to which such
     counsel need express no opinion), when they became effective or were filed
     with the Commission, as the case may be, complied as to form in all
     material respects with the requirements of the 1933 Act or the 1934 Act ,
     as applicable, and the rules and regulations of the Commission thereunder.

         (xiv)  The [each] applicable Indenture has been duly qualified under
     the 1939 Act.

         (xv) The Underwritten Securities, upon issuance, will be excluded or
     exempted under, or beyond the purview of, the Commodity Exchange Act, as
     amended (the

                                      E-3
<PAGE>

     "Commodity Exchange Act"), and the rules and regulations of the Commodity
     Futures Trading Commission under the Commodity Exchange Act (the "Commodity
     Exchange Act Regulations").

         (xvi)  The Company is not, and upon the issuance and sale of the
     Underwritten Securities as herein contemplated and the application of the
     net proceeds therefrom as described in the Prospectus will not be, an
     "investment company" within the meaning of the Investment Company Act of
     1940, as amended (the "1940 Act").

     Such counsel shall also state that it has been advised by the Commission
that the Registration Statement (including any Rule 462(b) Registration
Statement) became effective under the 1933 Act; that any required filings of the
Prospectus pursuant to Rule 424 (b) have been made in the manner and within the
time period required by Rule 424(b); and that, based solely on conversations
with the Commission, no stop order suspending the effectiveness of the
Registration Statement (or such Rule 462(b) Registration Statement) has been
issued and no proceedings for the purpose have been instituted, are pending or,
to such counsel's knowledge, are contemplated under the 1933 Act.

     Such counsel shall also state that they have examined various documents and
participated in conferences with representatives of the Company and the
Guarantor and their accountants and with representatives of the
Representative(s) and their counsel at which times the contents of the
Registration Statement and the Prospectus and related matters were discussed,
and that, although they are not passing upon and assume no responsibility for
the accuracy, completeness or fairness of the statements contained in the
Registration Statement or the Prospectus or making any representation that they
have independently verified or checked the accuracy, completeness or fairness of
such statements, except as set forth above, no facts have come to such counsel's
attention that cause such counsel to believe that the Registration Statement
(including any Rule 462(b) Registration Statement) or any post-effective
amendment thereto, at the time the Registration Statement (including any Rule
462(b) Registration Statement) or any post-effective amendment thereto
(including the filing of the Guarantor's Annual Report on Form 10-K with the
Commission) became effective or as of the date of the Terms Agreement, contained
any untrue statement of a material fact or omitted to state a material fact
required to be stated therein or necessary to make the statements therein not
misleading; or that the Prospectus or any amendment or supplement thereto, at
the date of the Prospectus, at the date of any such amendment or supplement or
at the Closing Time, included or includes any 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, in the light of the circumstances
under which they were made, not misleading (such counsel need not express a
belief with respect to the financial statements and supporting schedules and
other financial data included in or omitted from the Registration Statement
(including any Rule 462(b) Registration Statement) or any post-effective
amendment thereto or the Prospectus or any amendment or supplement thereto).

     [In rendering such opinion, such counsel may rely (A) as to matters
involving the application of laws other than the laws of the State of New York,
the corporate laws of the State of Delaware or the federal laws of the United
States of America, to the extent such counsel deems proper and specified in such
opinion, upon the opinion of other counsel whom such counsel believes to be
reliable (which opinion shall be dated and furnished to the Representative(s) at
the Closing Time, shall be satisfactory in form and substance to counsel for

                                      E-4

the Underwriters and shall expressly state that the Underwriters may rely on
such opinion as if it were addressed to them), provided that such counsel shall
state in their opinion that they believe that they and the Underwriters are
justified in relying upon such opinion, and (B) as to matters of fact (but not
as to legal conclusions), to the extent such counsel deems proper, on
certificates of responsible officers of the Company, its subsidiaries and public
officials.]

may be based, insofar as it relates to factual matters, upon a certificate or
opinion of, or representations by, an officer or officers of the Company stating
that the information with respect to such factual matters is in the possession
of the Company, provided that such counsel, after reasonable inquiry, has no

representations with respect to such matters are erroneous.

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

      Section 1.4. Acts of Holders.

            (1) Any request, demand, authorization, direction, notice, consent,
      waiver or other action provided by or pursuant to this Indenture to be
      given or taken by Holders may be embodied in and evidenced by one or more
      instruments of substantially similar tenor signed by such Holders in
      person or by an agent duly appointed in writing. If, but only if,
      Securities of a series are issuable as Bearer Securities, any request,
      demand, authorization, direction, notice, consent, waiver or other action
      provided in or pursuant to this Indenture to be given or taken by Holders
      of Securities of such series may, alternatively, be embodied in and
      evidenced by the record of Holders of Securities of such series voting in
      favor thereof, either in person or by proxies duly appointed in writing,
      at any meeting of Holders of Securities of such series duly called and
      held in accordance with the provisions of Article 15, or a combination of
      such instruments and any such record. Except as herein otherwise expressly
      provided, such action shall become effective when such instrument or
      instruments or record or both are delivered to the Trustee and, where it
      is hereby expressly required, to the Company. Such instrument or
      instruments and any such record (and the action embodied therein and
      evidenced thereby) are herein sometimes referred to as the "Act" of the
      Holders signing such instrument or instruments or so voting at any such
      meeting. Proof of execution of any such instrument or of a writing
      appointing any such agent, or of the holding by any Person of a Security,
      shall be sufficient for any purpose of this Indenture and (subject to
      Section 315 of the Trust Indenture Act) conclusive in favor of the Trustee
      and the Company and any agent of the Trustee or the Company, if made in
      the manner provided in this Section. The record of any meeting of Holders
      of Securities shall be proved in the manner provided in Section 15.6.

      Without limiting the generality of this Section 1.4, unless otherwise
provided in or pursuant to this Indenture, a Holder, including a U.S. Depository
that is a Holder of a global Security, may make, give or take, by a proxy or
proxies duly appointed in writing, any request, demand, authorization,
direction, notice, consent, waiver or other Act provided in or pursuant to this
Indenture to be made, given or taken by Holders, and a U.S. Depository that is a
Holder of a global Security may provide its proxy or proxies to the beneficial
owners of interests in any such global Security through such U.S. Depository's
standing instructions and customary practices.

      The Company shall fix a record date for the purpose of determining the
Persons who are beneficial owners of interest in any permanent global Security
held by a U.S. Depository entitled under the procedures of such U.S. Depository
to make, give or take, by a proxy or proxies duly appointed in writing, any
request, demand, authorization, direction, notice, consent, waiver or other Act
provided in or pursuant to this Indenture to be made, given or taken by Holders.
If such a record date is fixed, the Holders on such record date or their duly
appointed proxy or proxies, and only such Persons, shall be entitled to make,
give or take such request, demand, authorization, direction, notice, consent,
waiver or other Act, whether or not such Holders remain Holders after such
record date. No such request, demand, authorization, direction, notice, consent,
waiver or other Act shall be valid or effective if made, given or taken more
than 90 days after such record date.


                                       12
<PAGE>

            (2) The fact and date of the execution by any Person of any such
      instrument or writing referred to in this Section 1.4 may be proved in any
      reasonable manner; and the Trustee may in any instance require further
      proof with respect to any of the matters referred to in this Section.

            (3) The ownership, principal amount and serial numbers of Registered
      Securities held by any Person, and the date of the commencement and the
      date of the termination of holding the same, shall be proved by the
      Security Register.

            (4) The ownership, principal amount and serial numbers of Bearer
      Securities held by any Person, and the date of the commencement and the
      date of the termination of holding the same, may be proved by the
      production of such Bearer Securities or by a certificate executed, as
      depositary, by any trust company, bank, banker or other depositary
      reasonably acceptable to the Company, wherever situated, if such
      certificate shall be deemed by the Company and the Trustee to be
      satisfactory, showing that at the date therein mentioned such Person had
      on deposit with such depositary, or exhibited to it, the Bearer Securities
      therein described; or such facts may be proved by the certificate or
      affidavit of the Person holding such Bearer Securities, if such
      certificate or affidavit is deemed by the Trustee to be satisfactory. The
      Trustee and the Company may assume that such ownership of any Bearer
      Security continues until (i) another certificate or affidavit bearing a
      later date issued in respect of the same Bearer Security is produced, or
      (ii) such Bearer Security is produced to the Trustee by some other Person,
      or (iii) such Bearer Security is surrendered in exchange for a Registered
      Security, or (iv) such Bearer Security is no longer Outstanding. The
      ownership, principal amount and serial numbers of Bearer Securities held
      by the Person so executing such instrument or writing and the date of the
      commencement and the date of the termination of holding the same may also
      be proved in any other manner which the Company and the Trustee deem
      sufficient.

            (5) If the Company shall solicit from the Holders of any Registered
      Securities any request, demand, authorization, direction, notice, consent,
      waiver or other Act, the Company may at its option (but is not obligated
      to), by Board Resolution, fix in advance a record date for the
      determination of Holders of Registered Securities entitled to give such
      request, demand, authorization, direction, notice, consent, waiver or
      other Act. If such a record date is fixed, such request, demand,
      authorization, direction, notice, consent, waiver or other Act may be
      given before or after such record date, but only the Holders of Registered
      Securities of record at the close of business on such record date shall be
      deemed to be Holders for the purpose of determining whether Holders of the
      requisite proportion of Outstanding Securities have authorized or agreed
      or consented to such request, demand, authorization, direction, notice,
      consent, waiver or other Act, and for that purpose the Outstanding
      Securities shall be computed as of such record date; provided that no such
      authorization, agreement or consent by the Holders of Registered
      Securities shall be deemed effective unless it shall become effective
      pursuant to the provisions of this Indenture not later than six months
      after the record date.

            (6) Any request, demand, authorization, direction, notice, consent,
      waiver or other Act by the Holder of any Security shall bind every future
      Holder of the same Security and the Holder of every Security issued upon
      the registration of transfer thereof


                                       13
<PAGE>

      or in exchange therefor or in lieu thereof in respect of anything done or
      suffered to be done by the Trustee, any Security Registrar, any Paying
      Agent or the Company in reliance thereon, whether or not notation of such
      Act is made upon such Security.

      Section 1.5. Notices, etc. to Trustee and Company.

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

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

            (2) the Company by the Trustee or 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 the attention of its Treasurer, with a copy to the attention of its
      General Counsel, at the address of its principal office specified in the
      first paragraph of this instrument or at any other address previously
      furnished in writing to the Trustee by the Company.

      Section 1.6. Notice to Holders of Securities; Waiver.

      Except as otherwise expressly provided in or pursuant to this Indenture,
where this Indenture provides for notice to Holders of Securities of any event,

            (1) such notice shall be sufficiently given to Holders of Registered
      Securities if in writing and mailed, first-class postage prepaid, to each
      Holder of a Registered Security affected by such event, at his address as
      it appears in the Security Register, not later than the latest date, and
      not earlier than the earliest date, prescribed for the giving of such
      notice; and

            (2) such notice shall be sufficiently given to Holders of Bearer
      Securities, if any, if published in an Authorized Newspaper in The City of
      New York and, if such Securities are then listed on any stock exchange
      outside the United States, in an Authorized Newspaper in such city as the
      Company shall advise the Trustee that such stock exchange so requires, on
      a Business Day at least twice, the first such publication to be not
      earlier than the earliest date and the second such publication not later
      than the latest date prescribed for the giving of such notice.

      In any case where notice to Holders of Registered Securities is given by
mail, neither the failure to mail such notice, nor any defect in any notice so
mailed, to any particular Holder of a Registered Security shall affect the
sufficiency of such notice with respect to other Holders of Registered
Securities or the sufficiency of any notice to Holders of Bearer Securities
given as provided herein. Any notice which is mailed in the manner herein
provided shall be conclusively presumed to have been duly given or provided. In
the 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


                                       14
<PAGE>

by mail, then such notification as shall be made with the approval of the
Trustee shall constitute a sufficient notification for every purpose hereunder.

      In case by reason of the suspension of publication of any Authorized
Newspaper or Authorized Newspapers or by reason of any other cause it shall be
impracticable to publish any notice to Holders of Bearers Securities as provided
above, then such notification to Holders of Bearer Securities as shall be given
with the approval of the Trustee shall constitute sufficient notice to such
Holders for every purpose hereunder. Neither failure to give notice by
publication to Holders of Bearer Securities as provided above, nor any defect in
any notice so published, shall affect the sufficiency of any notice mailed to
Holders of Registered Securities as provided above.

      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 of Securities shall be filed with the Trustee, but
such filing shall not be a condition precedent to the validity of any action
taken in reliance upon such waiver.

      Section 1.7. Language of Notices.

      Any request, demand, authorization, direction, notice, consent, election
or waiver required or permitted under this Indenture shall be in the English
language, except that, if the Company so elects, any published notice may be in
an official language of the country of publication.

      Section 1.8. Conflict with Trust Indenture Act.

      If any provision hereof limits, qualifies or conflicts with any duties
under any required provision of the Trust Indenture Act imposed hereon by
Section 318(c) thereof, such required provision shall control.

      Section 1.9. Effect of Headings and Table of Contents.

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

      Section 1.10. Successors and Assigns.

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

      Section 1.11. Separability Clause.

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


                                       15

      Section 1.12. Benefits of Indenture.

      Nothing in this Indenture, any Security or any Coupon, express or implied,
shall give to any Person, other than the parties hereto, any Security Registrar,
any Paying Agent, any Authenticating Agent and their successors hereunder and
the Holders of Securities or Coupons, any benefit or any legal or equitable
right, remedy or claim under this Indenture.

      Section 1.13. Governing Law.

      This Indenture, the Securities and any Coupons shall be governed by and
construed in accordance with the laws of the State of New York applicable to
agreements made or instruments entered into and, in each case, performed in said
state.

      Section 1.14. Legal Holidays.

      Unless otherwise specified in or pursuant to this Indenture or any
Securities, in any case where any Interest Payment Date, Stated Maturity or
Maturity of any Security, or the last date on which a Holder has the right to
convert or exchange Securities of a series that are convertible or exchangeable,
shall be a Legal Holiday at any Place of Payment, then (notwithstanding any
other provision of this Indenture, any Security or any Coupon other than a
provision in any Security or Coupon that specifically states that such provision
shall apply in lieu hereof) payment need not be made at such Place of Payment on
such date, and such Securities need not be converted or exchanged on such date
but such payment may be made, and such Securities may be converted or exchanged,
on the next succeeding day that is a Business Day at such Place of Payment with
the same force and effect as if made on the Interest Payment Date or at the
Stated Maturity or Maturity or on such last day for conversion or exchange, and
no interest shall accrue on the amount payable on such date or at such time for
the period from and after such Interest Payment Date, Stated Maturity, Maturity
or last day for conversion or exchange, as the case may be, to such next
succeeding Business Day.

      Section 1.15. Counterparts.

      This Indenture may be executed in several counterparts, each of which
shall be an original and all of which shall constitute but one and the same
instrument.

      Section 1.16. Judgment Currency.

      The Company agrees, to the fullest extent that it may effectively do so
under applicable law, that (a) if for the purpose of obtaining judgment in any
court it is necessary to convert the sum due in respect of the principal of, or
premium or interest, if any, or Additional Amounts on the Securities of any
series (the "Required Currency") into a currency in which a judgment will be
rendered (the "Judgment Currency"), the rate of exchange used shall be the rate
at which in accordance with normal banking procedures the Trustee could purchase
in The City of New York the requisite amount of the Required Currency with the
Judgment Currency on the New York Banking Day preceding the day on which a final
unappealable judgment is given and (b) its obligations under this Indenture to
make payments in the Required Currency (i) shall not be discharged or satisfied
by any tender, or any recovery pursuant to any judgment (whether or not entered
in accordance with clause (a)), in any currency other than the Required
Currency, except


                                       16
<PAGE>

to the extent that such tender or recovery shall result in the actual receipt,
by the payee, of the full amount of the Required Currency expressed to be
payable in respect of such payments, (ii) shall be enforceable as an alternative
or additional cause of action for the purpose of recovering in the Required
Currency the amount, if any, by which such actual receipt shall fall short of
the full amount of the Required Currency so expressed to be payable and (iii)
shall not be affected by judgment being obtained for any other sum due under
this Indenture. For purposes of the foregoing, "New York Banking Day" means any
day except a Saturday, Sunday or a legal holiday in The City of New York or a
day on which banking institutions in The City of New York are authorized or
obligated by law, regulation or executive order to be closed.

      Section 1.17. No Security Interest Created.

      Subject to the provisions of Section 10.5, nothing in this Indenture or in
any Securities, express or implied, shall be construed to constitute a security
interest under the Uniform Commercial Code or similar legislation, as now or
hereafter enacted and in effect in any jurisdiction where property of the
Company or its Subsidiaries is or may be located.

      Section 1.18. Limitation on Individual Liability.

      No recourse under or upon any obligation, covenant or agreement contained
in this Indenture or in any Security, or for any claim based thereon or
otherwise in respect thereof, shall be had against any incorporator,
shareholder, officer or director, as such, past, present or future, of the
Company, either directly or through the Company, whether by virtue of any
constitution, statute or rule of law, or by the enforcement of any assessment or
penalty or otherwise; it being expressly understood that this Indenture and the
obligations issued hereunder are solely corporate obligations, and that no such
personal liability whatever shall attach to, or is or shall be incurred by, the
incorporators, shareholders, officers or directors, as such, of the Company, or
any of them, because of the creation of the indebtedness hereby authorized, or
under or by reason of the obligations, covenants or agreements contained in this
Indenture or in any Security or implied therefrom; and that any and all such
personal liability of every name and nature, either at common law or in equity
or by constitution or statute, of, and any and all such rights and claims
against, every such incorporator, shareholder, officer or director, as such,
because of the creation of the indebtedness hereby authorized, or under or by
reason of the obligations, covenants or agreements contained in this Indenture
or in any Security or implied therefrom, are hereby expressly waived and
released as a condition of, and as a consideration for, the execution of this
Indenture and the issuance of such Security.

      Section 1.19 Submission to Jurisdiction.

      The Company agrees that any judicial proceedings instituted in relation to
any matter arising under this Indenture, the Securities or any Coupons
appertaining thereto may be brought in any United States Federal or New York
State court sitting in the Borough of Manhattan, The City of New York, New York

      Unless otherwise provided in or pursuant to this Indenture or any
Securities, the Securities shall not be issuable in temporary or permanent
global form. If Securities of a series shall be issuable in global form, any

endorsed thereon and may also provide that the aggregate amount of Outstanding

respect to a Security in global form shall be in writing but need not be
accompanied by or contained in an Officer's Certificate and need not be
accompanied by an Opinion of Counsel.

      Notwithstanding the provisions of Section 3.7, unless otherwise specified
in or pursuant to this Indenture or any Securities, payment of principal of, any
premium and interest on, and any Additional Amounts in respect of, any Security
in temporary or permanent global form shall be made to the Person or Persons
specified therein.

      Notwithstanding the provisions of Section 3.8 and except as provided in
the preceding paragraph, the Company, the Trustee and any agent of the Company
or the Trustee shall treat as the Holder of such principal amount of Outstanding
Securities represented by a global Security

global Security in registered form, or (ii) in the case of a global Security in

<PAGE>

denominated in Dollars shall be issuable in registered form without Coupons in
denominations of $1,000 and any integral multiple thereof, and the Bearer
Securities denominated in Dollars shall be issuable in the denomination of
$5,000. Securities not denominated in Dollars shall be issuable in such
denominations as are established with respect to such Securities in or pursuant

      Section 3.3. Execution, Authentication, Delivery and Dating.

      Securities shall be executed on behalf of the Company by its Chairman of
the Board, a Vice Chairman, its President, Chief Financial Officer, Chief
Investment Officer or Chief Accounting Officer under its corporate seal
reproduced thereon and attested by its Secretary. Coupons shall be executed on
behalf of the Company by the Chief Financial Officer or Chief Accounting Officer
of the Company. The signature of any of these officers on the Securities or any
Coupons appertaining thereto may be manual or facsimile.

      Securities and any Coupons appertaining thereto 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 Securities and Coupons or did not hold such offices at the date
of original issuance of such Securities or Coupons.

      At any time and from time to time after the execution and delivery of this
Indenture, the Company may deliver Securities, together with any Coupons
appertaining thereto, executed by the Company, to the Trustee for authentication
and, provided that the Board Resolution and Officer's Certificate or
supplemental indenture or indentures with respect to such Securities referred to
in Section 3.1 and a Company Order for the authentication and delivery of such
Securities have been delivered to the Trustee, the Trustee in accordance with
the Company Order and subject to the provisions hereof and of such Securities
shall authenticate and deliver such Securities. In authenticating such
Securities, and accepting the additional responsibilities under this Indenture
in relation to such Securities and any Coupons appertaining thereto, the Trustee
shall be entitled to receive, and (subject to Sections 315(a) through 315(d) of
the Trust Indenture Act) shall be fully protected in relying upon,

            (1) an Opinion of Counsel to the effect that:

                  (a) the form or forms and terms of such Securities and
            Coupons, if any, have been established in conformity with the
            provisions of this Indenture;

                  (b) all conditions precedent to the authentication and
            delivery of such Securities and Coupons, if any, appertaining
            thereto, have been complied with and that such Securities and
            Coupons, when completed by appropriate insertions, executed under
            the Company's corporate seal and attested by duly authorized
            officers of the Company, delivered by duly authorized officers of
            the Company to the Trustee for authentication pursuant to this
            Indenture, and authenticated and delivered by the Trustee and issued
            by the Company in the manner and subject to any conditions specified
            in such Opinion of Counsel, will constitute legally valid and
            binding obligations of the Company, enforceable against the Company
            in


                                       24
<PAGE>

            accordance with their terms, except as enforcement thereof may be
            subject to or limited by bankruptcy, insolvency, reorganization,
            moratorium, arrangement, fraudulent conveyance, fraudulent transfer
            or other similar laws relating to or affecting creditors' rights
            generally, and subject to general principles of equity (regardless
            of whether enforcement is sought in a proceeding in equity or at
            law) and will entitle the Holders thereof to the benefits of this
            Indenture; such Opinion of Counsel need express no opinion as to the
            availability of equitable remedies;

                  (c) all laws and requirements in respect of the execution and
            delivery by the Company of such Securities and Coupons, if any, have
            been complied with; and

                  (d) this Indenture has been qualified under the Trust
            Indenture Act; and

            (2) an Officer's Certificate stating that all conditions precedent
      to the execution, authentication and delivery of such Securities and
      Coupons, if any, appertaining thereto, have been complied with and that,
      to the best knowledge of the Persons executing such certificate, no event
      which is, or after notice or lapse of time would become, an Event of
      Default with respect to any of the Securities shall have occurred and be
      continuing.

      If all the Securities of any series are not to be issued at one time, it
shall not be necessary to deliver an Opinion of Counsel and an Officer's
Certificate at the time of issuance of each Security, but such opinion and
certificate, with appropriate modifications, shall be delivered at or before the
time of issuance of the first Security of such series. After any such first
delivery, any separate written request by an Authorized Officer of the Company
or any person designated in writing by an Authorized Officer that the Trustee
authenticate and deliver Securities of such series for original issue will be
deemed to be a certification by the Company that all conditions precedent
provided for in this Indenture relating to authentication and delivery of such
Securities continue to have been complied with.

      The Trustee shall not be required to authenticate or to cause an
Authenticating Agent to authenticate any Securities if the issue of such
Securities pursuant to this Indenture will affect the Trustee's own rights,
duties or immunities under the Securities and this Indenture or otherwise in a
manner which is not reasonably acceptable to the Trustee or if the Trustee,
being advised by counsel, determines that such action may not lawfully be taken.

      Each Registered Security shall be dated the date of its authentication.
Each Bearer Security and any Bearer Security in global form shall be dated as of
the date specified in or pursuant to this Indenture.

      No Security or Coupon appertaining thereto shall be entitled to any
benefit under this Indenture or be valid or obligatory for any purpose, unless
there appears on such Security a certificate of authentication substantially in
the form provided for in Section 2.2 or 6.11 executed by or on behalf of the
Trustee or by the Authenticating Agent by the manual signature of one of its
authorized officers. Such certificate upon any Security shall be conclusive
evidence, and the


                                       25
<PAGE>

only evidence, that such Security has been duly authenticated and delivered
hereunder. Except as permitted by Section 3.6 or 3.7, the Trustee shall not
authenticate and deliver any Bearer Security unless all Coupons appertaining
thereto then matured have been detached and cancelled.

      Section 3.4. Temporary Securities.

      Pending the preparation of definitive Securities, the Company may execute
and deliver to the Trustee and, upon Company Order, the Trustee shall
authenticate and deliver, in the manner provided in Section 3.3, temporary
Securities in lieu thereof which are printed, lithographed, typewritten,
mimeographed or otherwise produced, in any authorized denomination,
substantially of the tenor of the definitive Securities in lieu of which they
are issued, in registered form or, if authorized in or pursuant to this
Indenture, in bearer form with one or more Coupons or without Coupons and with
such appropriate insertions, omissions, substitutions and other variations as
the officers of the Company executing such Securities may determine, as
conclusively evidenced by their execution of such Securities. Such temporary
Securities may be in global form.

      Except in the case of temporary Securities in global form, which shall be
exchanged in accordance with the provisions thereof, if temporary Securities are
issued, the Company shall cause definitive Securities to be prepared without
unreasonable delay. After the preparation of definitive Securities of the same
series and containing terms and provisions that are identical to those of any
temporary Securities, such temporary Securities shall be exchangeable for such
definitive Securities upon surrender of such temporary Securities at an Office
or Agency for such Securities, without charge to any Holder thereof. Upon
surrender for cancellation of any one or more temporary Securities (accompanied
by any unmatured Coupons appertaining thereto), the Company shall execute and
the Trustee shall authenticate and deliver in exchange therefor a like principal
amount of definitive Securities of authorized denominations of the same series
and containing identical terms and provisions; provided, however, that no
definitive Bearer Security, except as provided in or pursuant to this Indenture,
shall be delivered in exchange for a temporary Registered Security; and
provided, further, that a definitive Bearer Security shall be delivered in
exchange for a temporary Bearer Security only in compliance with the conditions
set forth in or pursuant to this Indenture. Unless otherwise provided in or
pursuant to this Indenture with respect to a temporary global Security, until so
exchanged the temporary Securities of any series shall in all respects be
entitled to the same benefits under this Indenture as definitive Securities of
such series.

      Section 3.5. Registration, Transfer and Exchange.

      With respect to the Registered Securities of each series, if any, the
Company shall cause to be kept a register (each such register being herein
sometimes referred to as the "Security Register") at an Office or Agency for
such series in which, subject to such reasonable regulations as it may
prescribe, the Company shall provide for the registration of the Registered
Securities of such series and of transfers of the Registered Securities of such
series. Such Office or Agency shall be the "Security Registrar" for that series
of Securities. Unless otherwise specified in or pursuant to this Indenture or
the Securities, the Trustee shall be the initial Security Registrar for each
series of Securities. The Company shall have the right to remove and replace
from time to time the Security Registrar for any series of Securities; provided
that no such removal or replacement shall be effective until a successor
Security Registrar with respect to such series of


                                       26
<PAGE>

Securities shall have been appointed by the Company and shall have accepted such
appointment by the Company. In the event that the Trustee shall not be or shall
cease to be Security Registrar with respect to a series of Securities, it shall
have the right to examine the Security Register for such series at all
reasonable times. There shall be only one Security Register for each series of
Securities.

      Upon surrender for registration of transfer of any Registered Security of
any series at any Office or Agency for such series, the Company shall execute,
and the Trustee shall authenticate and deliver, in the name of the designated
transferee or transferees, one or more new Registered Securities of the same
series denominated as authorized in or pursuant to this Indenture, of a like
aggregate principal amount bearing a number not contemporaneously outstanding
and containing identical terms and provisions.

      At the option of the Holder, Registered Securities of any series may be
exchanged for other Registered Securities of the same series containing
identical terms and provisions, in any authorized denominations, and of a like
aggregate principal amount, upon surrender of the Securities to be exchanged at
any Office or Agency for such series. Whenever any Registered Securities are so
surrendered for exchange, the Company shall execute, and the Trustee shall
authenticate and deliver, the Registered Securities which the Holder making the
exchange is entitled to receive.

      If provided in or pursuant to this Indenture, with respect to Securities
of any series, at the option of the Holder, Bearer Securities of such series may
be exchanged for Registered Securities of such series containing identical
terms, denominated as authorized in or pursuant to this Indenture and in the
same aggregate principal amount, upon surrender of the Bearer Securities to be
exchanged at any Office or Agency for such series, with all unmatured Coupons
and all matured Coupons in default thereto appertaining. If the Holder of a
Bearer Security is unable to produce any such unmatured Coupon or Coupons or
matured Coupon or Coupons in default, such exchange may be effected if the
Bearer Securities are accompanied by payment in funds acceptable to the Company
and the Trustee in an amount equal to the face amount of such missing Coupon or
Coupons, or the surrender of such missing Coupon or Coupons may be waived by the
Company and the Trustee if there is furnished to them such security or indemnity
as they may require to save each of them and any Paying Agent harmless. If
thereafter the Holder of such Bearer Security shall surrender to any Paying
Agent any such missing Coupon in respect of which such a payment shall have been
made, such Holder shall be entitled to receive the amount of such payment;
provided, however, that, except as otherwise provided in Section 10.2, interest
represented by Coupons shall be payable only upon presentation and surrender of
those Coupons at an Office or Agency for such series located outside the United
States. Notwithstanding the foregoing, in case a Bearer Security of any series
is surrendered at any such Office or Agency for such series in exchange for a
Registered Security of such series and like tenor after the close of business at
such Office or Agency on (i) any Regular Record Date and before the opening of
business at such Office or Agency on the next succeeding Interest Payment Date,
or (ii) any Special Record Date and before the opening of business at such
Office or Agency on the related date for payment of Defaulted Interest, such
Bearer Security shall be surrendered without the Coupon relating to such
Interest Payment Date or proposed date of payment, as the case may be (or, if
such Coupon is so surrendered with such Bearer Security, such Coupon shall be
returned to the Person so surrendering the Bearer Security), and interest or


                                       27
<PAGE>

Defaulted Interest, as the case may be, shall not be payable on such Interest
Payment Date or proposed date for payment, as the case may be, in respect of the
Registered Security issued in exchange for such Bearer Security, but shall be
payable only to the Holder of such Coupon when due in accordance with the
provisions of this Indenture.

      If provided in or pursuant to this Indenture with respect to Securities of
any series, at the option of the Holder, Registered Securities of such series
may be exchanged for Bearer Securities upon such terms and conditions as may be
provided in or pursuant to this Indenture with respect to such series.

      Whenever any Securities are surrendered for exchange as contemplated by
the immediately preceding two paragraphs, the Company shall execute, and the
Trustee shall authenticate and deliver, the Securities which the Holder making
the exchange is entitled to receive.

      Notwithstanding the foregoing, except as otherwise provided in or pursuant
to this Indenture, any global Security shall be exchangeable for definitive
Securities only if (i) the Depository is at any time unwilling, unable or
ineligible to continue as depository and a successor depository is not appointed
by the Company within 90 days of the date the Company is so informed in writing,
(ii) the Company executes and delivers to the Trustee a Company Order to the
effect that such global Security shall be so exchangeable, or (iii) an Event of
Default has occurred and is continuing with respect to the Securities. If the
beneficial owners of interests in a global Security are entitled to exchange
such interests for definitive Securities as the result of an event described in
clause (i), (ii) or (iii) of the preceding sentence, then without unnecessary
delay but in any event not later than the earliest date on which such interests
may be so exchanged, the Company shall deliver to the Trustee definitive
Securities in such form and denominations as are required by or pursuant to this
Indenture, and of the same series, containing identical terms and in aggregate
principal amount equal to the principal amount of such global Security, executed
by the Company. On or after the earliest date on which such interests may be so
exchanged, such global Security shall be surrendered from time to time by the
U.S. Depository or such other Depository as shall be specified in the Company
Order with respect thereto, and in accordance with instructions given to the
Trustee and the U.S. Depository or such other Depository, as the case may be
(which instructions shall be in writing but need not be contained in or
accompanied by an Officer's Certificate or be accompanied by an Opinion of
Counsel), as shall be specified in the Company Order with respect thereto to the
Trustee, as the Company's agent for such purpose, to be exchanged, in whole or
in part, for definitive Securities as described above without charge. The
Trustee shall authenticate and make available for delivery, in exchange for each
portion of such surrendered global Security, a like aggregate principal amount
of definitive Securities of the same series of authorized denominations and of
like tenor as the portion of such global Security to be exchanged, which (unless
such Securities are not issuable both as Bearer Securities and as Registered
Securities, in which case the definitive Securities exchanged for the global
Security shall be issuable only in the form in which the Securities are
issuable, as provided in or pursuant to this Indenture) shall be in the form of
Bearer Securities or Registered Securities, or any combination thereof, as shall
be specified by the beneficial owner thereof, but subject to the satisfaction of
any certification or other requirements to the issuance of Bearer Securities;
provided, however, that no such exchanges may occur during a period beginning at
the opening of business 15 days before any


                                       28
<PAGE>

selection of Securities of the same series to be redeemed and ending on the
relevant Redemption Date; and provided, further, that (unless otherwise provided
in or pursuant to this Indenture) no Bearer Security delivered in exchange for a
portion of a global Security shall be mailed or otherwise delivered to any
location in the United States. Promptly following any such exchange in part,
such global Security shall be returned by the Trustee to such Depository or the
U.S. Depository, as the case may be, or such other Depository or U.S. Depository
referred to above in accordance with the instructions of the Company referred to
above. If a Registered Security is issued in exchange for any portion of a
global Security after the close of business at the Office or Agency for such
Security where such exchange occurs on or after (i) any Regular Record Date for
such Security and before the opening of business at such Office or Agency on the
next succeeding Interest Payment Date, or (ii) any Special Record Date for such
Security and before the opening of business at such Office or Agency on the
related proposed date for payment of interest or Defaulted Interest, as the case
may be, interest shall not be payable on such Interest Payment Date or proposed
date for payment, as the case may be, in respect of such Registered Security,
but shall be payable on such Interest Payment Date or proposed date for payment,
as the case may be, only to the Person to whom interest in respect of such
portion of such global Security shall be payable in accordance with the
provisions of this Indenture.

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

      Every Registered Security presented or surrendered for registration of
transfer or for exchange or redemption shall (if so required by the Company or
the Security Registrar for such Security) be duly endorsed, or be accompanied by
a written instrument of transfer in form satisfactory to the Company and the
Security Registrar for such Security 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, or redemption of Securities, but the Company may require payment of a
sum sufficient to cover any tax or other governmental charge and any other
expenses (including fees and expenses of the Trustee) that may be imposed in
connection with any registration of transfer or exchange of Securities, other
than exchanges pursuant to Section 3.4, 9.5 or 11.7 not involving any transfer.

      Except as otherwise provided in or pursuant to this Indenture, the Company
shall not be required (i) to issue, register the transfer of or exchange any
Securities during a period beginning at the opening of business 15 days before
the day of mailing of a notice of redemption of Securities of like tenor and the
same series under Section 11.3 and ending at the close of business on the day of
such mailing, or (ii) to register the transfer of or exchange any Registered
Security selected for redemption in whole or in part, except in the case of any
Security to be redeemed in part, the portion thereof not to be redeemed, or
(iii) to exchange any Bearer Security selected for redemption except, to the
extent provided with respect to such Bearer Security, that such Bearer Security
may be exchanged for a Registered Security of like tenor and the same series,
provided that such Registered Security shall be immediately surrendered for
redemption with written instruction for payment consistent with the provisions
of this Indenture or (iv) to issue, register the transfer of or exchange any
Security which, in accordance with its terms, has been


                                       29
<PAGE>

surrendered for repayment at the option of the Holder, except the portion, if
any, of such Security not to be so repaid.

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

      If any mutilated Security or a Security with a mutilated Coupon
appertaining to it is surrendered to the Trustee, subject to the provisions of
this Section 3.6, the Company shall execute and the Trustee shall authenticate
and deliver in exchange therefor a new Security of the same series containing
identical terms and of like principal amount and bearing a number not
contemporaneously outstanding, with Coupons appertaining thereto corresponding
to the Coupons, if any, appertaining to the surrendered Security.

      If there be delivered to the Company and to the Trustee (i) evidence to
their satisfaction of the destruction, loss or theft of any Security or Coupon,
and (ii) such security 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 Security or Coupon has been acquired by a
bona fide purchaser, the Company shall execute and, upon the Company's request
the Trustee shall authenticate and deliver, in exchange for or in lieu of any
such mutilated, destroyed, lost or stolen Security or in exchange for the
Security to which a destroyed, lost or stolen Coupon appertains with all
appurtenant Coupons not destroyed, lost or stolen, a new Security of the same
series containing identical terms and of like principal amount and bearing a
number not contemporaneously outstanding, with Coupons appertaining thereto
corresponding to the Coupons, if any, appertaining to such destroyed, lost or
stolen Security or to the Security to which such destroyed, lost or stolen
Coupon appertains.

      Notwithstanding the foregoing provisions of this Section 3.6, in case any
mutilated, destroyed, lost or stolen Security or Coupon has become or is about
to become due and payable, the Company in its discretion may, instead of issuing
a new Security, pay such Security or Coupon; provided, however, that payment of
principal of, any premium or interest on or any Additional Amounts with respect
to any Bearer Securities shall, except as otherwise provided in Section 10.2, be
payable only at an Office or Agency for such Securities located outside the
United States and, unless otherwise provided in or pursuant to this Indenture,
any interest on Bearer Securities and any Additional Amounts with respect to
such interest shall be payable only upon presentation and surrender of the
Coupons appertaining thereto.

      Upon the issuance of any new Security under this Section 3.6, the Company
may require the payment of a sum sufficient to cover any tax or other
governmental charge that may be imposed in relation thereto and any other
expenses (including the fees and expenses of the Trustee) connected therewith.

      Every new Security, with any Coupons appertaining thereto issued pursuant
to this Section 3.6 in lieu of any destroyed, lost or stolen Security, or in
exchange for a Security to which a destroyed, lost or stolen Coupon appertains
shall constitute a separate obligation of the Company, whether or not the
destroyed, lost or stolen Security and Coupons appertaining thereto or the
destroyed, lost or stolen Coupon shall be at any time enforceable by anyone, and
shall be entitled to all the benefits of this Indenture equally and
proportionately with any and all other Securities of such series and any
Coupons, if any, duly issued hereunder.


                                       30
<PAGE>

      The provisions of this Section 3.6, as amended or supplemented pursuant to
this Indenture with respect to particular Securities or generally, shall be
exclusive and shall preclude (to the extent lawful) all other rights and
remedies with respect to the replacement or payment of mutilated, destroyed,
lost or stolen Securities or Coupons.

      Section 3.7. Payment of Interest and Certain Additional Amounts; Rights to
Interest and Certain Additional Amounts Preserved.

      Unless otherwise provided in or pursuant to this Indenture, any interest
on and any Additional Amounts with respect to any Registered Security which
shall be payable, and are punctually paid or duly provided for, on any Interest
Payment Date shall be paid to the Person in whose name such Security (or one or
more Predecessor Securities) is registered as of the close of business on the
Regular Record Date for such interest.

      Unless otherwise provided in or pursuant to this Indenture, any interest
on and any Additional Amounts with respect to any Registered Security which
shall be payable, but shall not be punctually paid or duly provided for, on any
Interest Payment Date for such Registered Security (herein called "Defaulted
Interest") shall forthwith cease to be payable to the Holder thereof on the
relevant Regular Record Date by virtue of having been such Holder; and such
Defaulted Interest may be paid by the Company, at its election in each case, as
provided in Clause (1) or (2) below:

            (1) The Company may elect to make payment of any Defaulted Interest
      to the Person in whose name such Registered Security (or a Predecessor
      Security thereof) shall be registered at the close of business on a
      Special Record Date for the payment of such Defaulted Interest, which
      shall be fixed by the Company in the following manner. The Company shall
      notify the Trustee in writing of the amount of Defaulted Interest proposed
      to be paid on such Registered Security, the Special Record Date therefor
      and the date of the proposed payment, and at the same time the Company
      shall deposit with the Trustee an amount of money equal to the aggregate
      amount proposed to be paid in respect of such Defaulted Interest or shall
      make arrangements satisfactory to the Trustee for such deposit on or prior
      to the date of the proposed payment, such money when so deposited to be
      held in trust for the benefit of the Person entitled to such Defaulted
      Interest as in this Clause provided. The Special Record Date for the
      payment of such Defaulted Interest 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 notification to the Trustee of the proposed payment.
      The Trustee shall, in the name and at the expense of the Company, cause
      notice of the proposed payment of such Defaulted Interest and the Special
      Record Date therefor to be mailed, first-class postage prepaid, to the
      Holder of such Registered Security (or a Predecessor Security thereof) at
      his address as it appears in the Security Register not less than 10 days
      prior to such Special Record Date. The Trustee may, in its discretion, in
      the name and at the expense of the Company cause a similar notice to be
      published at least once in an Authorized Newspaper of general circulation
      in the Borough of Manhattan, The City of New York, but such publication
      shall not be a condition precedent to the establishment of such Special
      Record Date. Notice of the proposed payment of such Defaulted Interest and
      the Special Record Date therefor having been mailed as aforesaid, such
      Defaulted Interest shall be paid to the Person in whose name such
      Registered


                                       31
<PAGE>

      Security (or a Predecessor Security thereof) shall be registered at the
      close of business on such Special Record Date and shall no longer be
      payable pursuant to the following clause (2).

            (2) The Company may make payment of any Defaulted Interest in any
      other lawful manner not inconsistent with the requirements of any
      securities exchange on which such Security may be listed, and 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,
      such payment shall be deemed practicable by the Trustee.

      Unless otherwise provided in or pursuant to this Indenture or the
Securities of any particular series pursuant to the provisions of this
Indenture, at the option of the Company, interest on Registered Securities that
bear interest may be paid by mailing a check to the address of the Person
entitled thereto as such address shall appear in the Security Register or by
transfer to an account maintained by the payee with a bank located in the United
States.

      Subject to the foregoing provisions of this Section and Section 3.5, each
Security delivered under this Indenture upon registration of transfer of or in
exchange for or in lieu of any other Security shall carry the rights to interest
accrued and unpaid, and to accrue, which were carried by such other Security.

      In the case of any Registered Security of any series that is convertible
into shares of Common Stock of the Company or exchangeable for other securities,
which Registered Security is converted or exchanged after any Regular Record
Date and on or prior to the next succeeding Interest Payment Date (other than
any Registered Security with respect to which the Stated Maturity is prior to
such Interest Payment Date), interest with respect to which the Stated Maturity
is on such Interest Payment Date shall be payable on such Interest Payment Date
notwithstanding such conversion or exchange, and such interest (whether or not
punctually paid or duly provided for) shall be paid to the Person in whose name
that Registered Security (or one or more predecessor Registered Securities) is
registered at the close of business on such Regular Record Date. Except as
otherwise expressly provided in the immediately preceding sentence, in the case
of any Registered Security which is converted or exchanged, interest with
respect to which the Stated Maturity is after the date of conversion or exchange
of such Registered Security shall not be payable.

      Section 3.8. Persons Deemed Owners.

      Prior to due presentment of a Registered Security 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 Registered Security is registered in the
Security Register as the owner of such Registered Security for the purpose of
receiving payment of principal of, any premium and (subject to Sections 3.5 and
3.7) interest on and any Additional Amounts with respect to such Registered
Security and for all other purposes whatsoever, whether or not any payment with
respect to such Registered Security shall be overdue, and none of the Company,
the Trustee or any agent of the Company or the Trustee shall be affected by
notice to the contrary.


                                       32
<PAGE>

      The Company, the Trustee and any agent of the Company or the Trustee may
treat the bearer of any Bearer Security or the bearer of any Coupon as the
absolute owner of such Security or Coupon for the purpose of receiving payment
thereof or on account thereof and for all other purposes whatsoever, whether or
not any payment with respect to such Security or Coupon shall be overdue, and
none of the Company, the Trustee or any agent of the Company or the Trustee
shall be affected by notice to the contrary.

      No Holder of any beneficial interest in any global Security held on its
behalf by a Depository shall have any rights under this Indenture with respect
to such global Security, and such Depository may be treated by the Company, the
Trustee, and any agent of the Company or the Trustee as the owner of such global
Security for all purposes whatsoever. None of the Company, the Trustee, any
Paying Agent or the Security Registrar will have any responsibility or liability
for any aspect of the records relating to or payments made on account of
beneficial ownership interests of a global Security or for maintaining,
supervising or reviewing any records relating to such beneficial ownership
interests.

      Section 3.9. Cancellation.

      All Securities and Coupons surrendered for payment, redemption,
registration of transfer, exchange or conversion or for credit against any
sinking fund payment shall, if surrendered to any Person other than the Trustee,
be delivered to the Trustee, and any such Securities and Coupons, as well as
Securities and Coupons surrendered directly to the Trustee for any such purpose,
shall be cancelled promptly by the Trustee. The Company may at any time deliver
to the Trustee for cancellation any Securities previously authenticated and
delivered hereunder which the Company may have acquired in any manner
whatsoever, and all Securities so delivered shall be cancelled promptly by the
Trustee. No Securities shall be authenticated in lieu of or in exchange for any
Securities cancelled as provided in this Section, except as expressly permitted
by or pursuant to this Indenture. All cancelled Securities and Coupons held by
the Trustee shall be destroyed by the Trustee, unless by a Company Order the
Company directs their return to it.

      Section 3.10. Computation of Interest.

      Except as otherwise provided in or pursuant to this Indenture or in any
Security, interest on the Securities shall be computed on the basis of a 360-day
year of twelve 30-day months.

                     SATISFACTION AND DISCHARGE OF INDENTURE

      Section 4.1. Satisfaction and Discharge.

      Upon the direction of the Company by a Company Order, this Indenture shall
cease to be of further effect with respect to any series of Securities specified
in such Company Order and any Coupons appertaining thereto, and the Trustee, on
receipt of a Company Order, at the expense of the Company, shall execute proper
instruments acknowledging satisfaction and discharge of this Indenture as to
such series, when

            and delivered and all Coupons appertaining thereto (other than (i)
            Coupons appertaining to Bearer Securities of such series surrendered
            in exchange for Registered Securities of such series and maturing
            after such exchange whose surrender is not required or has been
            waived as provided in Section 3.5, (ii) Securities and Coupons of
            such series which have been destroyed, lost or stolen and which have
            been replaced or paid as provided in Section 3.6, (iii) Coupons

            maturing after the relevant Redemption Date whose surrender has been
            waived as provided in Section 11.7, and (iv) Securities and Coupons
            of such series for whose payment money has theretofore been
            deposited in trust or segregated and held in trust by the Company

            as provided in Section 10.3) have been delivered to the Trustee for
            cancellation; or

                  (b) all Securities of such series and, in the case of (i) or
            (ii) below, any Coupons appertaining thereto not theretofore
            delivered to the Trustee for cancellation

                        (i) have become due and payable, or

                        (ii) will become due and payable at their Stated
                  Maturity within one year, or

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

      and the Company, in the case of (i), (ii) or (iii) above, has deposited or
      caused to be deposited with the Trustee as trust funds in trust for such
      purpose, money in the Currency in which such Securities are payable in an
      amount sufficient to pay and discharge the entire indebtedness on such
      Securities and any Coupons appertaining thereto not theretofore delivered
      to the Trustee for cancellation, including the principal of, any premium
      and interest on, and any Additional Amounts with respect to such
      Securities and any Coupons appertaining thereto, to the date of such
      deposit (in the case of Securities which have become due and payable) or
      to the Maturity thereof, as the case may be;

            (2) the Company has paid or caused to be paid all other sums payable
      hereunder by the Company with respect to the Outstanding Securities of
      such series and any Coupons appertaining thereto; and

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


                                       34
<PAGE>

      In the event there are Securities of two or more series hereunder, the
Trustee shall be required to execute an instrument acknowledging satisfaction
and discharge of this Indenture only if requested to do so with respect to
Securities of such series as to which it is Trustee and if the other conditions
thereto are met.

      Notwithstanding the satisfaction and discharge of this Indenture with
respect to any series of Securities, the obligations of the Company to the
Trustee under Section 6.6 and, if money shall have been deposited with the
Trustee pursuant to subclause (b) of clause (1) of this Section, the obligations
of the Company and the Trustee with respect to the Securities of such series
under Sections 3.5, 3.6, 4.3, 10.2 and 10.3, with respect to the payment of
Additional Amounts, if any, with respect to such Securities as contemplated by
Section 10.4 (but only to the extent that the Additional Amounts payable with
respect to such Securities exceed the amount deposited in respect of such
Additional Amounts pursuant to Section 4.1(1)(b)), and with respect to any
rights to convert or exchange such Securities into Common Stock of the Company
or other securities shall survive.

      Section 4.2. Defeasance and Covenant Defeasance.

            (1) Unless pursuant to Section 3.1, either or both of (i) defeasance
      of the Securities of or within a series under clause (2) of this Section
      4.2 shall not be applicable with respect to the Securities of such series
      or (ii) covenant defeasance of the Securities of or within a series under
      clause (3) of this Section 4.2 shall not be applicable with respect to the
      Securities of such series, then such provisions, together with the other
      provisions of this Section 4.2 (with such modifications thereto as may be
      specified pursuant to Section 3.1 with respect to any Securities), shall
      be applicable to such Securities and any Coupons appertaining thereto, and
      the Company may at its option by Board Resolution, at any time, with
      respect to such Securities and any Coupons appertaining thereto, elect to
      have Section 4.2(2) or Section 4.2(3) be applied to such Outstanding
      Securities and any Coupons appertaining thereto upon compliance with the
      conditions set forth below in this Section 4.2.

            (2) Upon the Company's exercise of the above option applicable to
      this Section 4.2(2) with respect to any Securities of or within a series,
      the Company shall be deemed to have been discharged from its obligations
      with respect to such Outstanding Securities and any Coupons appertaining
      thereto on the date the conditions set forth in clause (4) of this Section
      4.2 are satisfied (hereinafter, "defeasance"). For this purpose, such
      defeasance means that the Company shall be deemed to have paid and
      discharged the entire Indebtedness represented by such Outstanding
      Securities and any Coupons appertaining thereto, which shall thereafter be
      deemed to be "Outstanding" only for the purposes of clause (5) of this
      Section 4.2 and the other Sections of this Indenture referred to in
      clauses (i) and (ii) below, and to have satisfied all of its other
      obligations under such Securities and any Coupons appertaining thereto and
      this Indenture insofar as such Securities and any Coupons appertaining
      thereto are concerned (and the Trustee, at the expense of the Company,
      shall execute proper instruments acknowledging the same), except for the
      following which shall survive until otherwise terminated or discharged
      hereunder: (i) the rights of Holders of such Outstanding Securities and
      any Coupons appertaining thereto to receive, solely from the trust fund
      described in clause (4) of this


                                       35
<PAGE>

      Section 4.2 and as more fully set forth in such clause, payments in
      respect of the principal of (and premium, if any) and interest, if any,
      on, and Additional Amounts, if any, with respect to, such Securities and
      any Coupons appertaining thereto when such payments are due, and any
      rights of such Holder to convert such Securities into Common Stock of the
      Company or exchange such Securities for other securities, (ii) the
      obligations of the Company and the Trustee with respect to such Securities
      under Sections 3.5, 3.6, 10.2 and 10.3 and with respect to the payment of
      Additional Amounts, if any, on such Securities as contemplated by Section
      10.4 (but only to the extent that the Additional Amounts payable with
      respect to such Securities exceed the amount deposited in respect of such
      Additional Amounts pursuant to Section 4.2(4)(a) below), and with respect
      to any rights to convert such Securities into Common Stock of the Company
      or exchange such Securities for other securities, (iii) the rights,
      powers, trusts, duties and immunities of the Trustee hereunder and (iv)
      this Section 4.2. The Company may exercise its option under this Section
      4.2(2) notwithstanding the prior exercise of its option under clause (3)
      of this Section 4.2 with respect to such Securities and any Coupons
      appertaining thereto.

            (3) Upon the Company's exercise of the option to have this Section
      4.2(3) apply with respect to any Securities of or within a series, the
      Company shall be released from its obligations under Sections 10.5 and
      10.6, and, to the extent specified pursuant to Section 3.1(19), any other
      covenant applicable to such Securities, with respect to such Outstanding
      Securities and any Coupons appertaining thereto on and after the date the
      conditions set forth in clause (4) of this Section 4.2 are satisfied
      (hereinafter, "covenant defeasance"), and such Securities and any Coupons
      appertaining thereto shall thereafter be deemed to be not "Outstanding"
      for the purposes of any direction, waiver, consent or declaration or Act
      of Holders (and the consequences of any thereof) in connection with any
      such covenant, but shall continue to be deemed "Outstanding" for all other
      purposes hereunder. For this purpose, such covenant defeasance means that,
      with respect to such Outstanding Securities and any Coupons appertaining
      thereto, the Company may omit to comply with, and shall have no liability
      in respect of, any term, condition or limitation set forth in any such
      Section or such other covenant, whether directly or indirectly, by reason
      of any reference elsewhere herein to any such Section or such other
      covenant or by reason of reference in any such Section or such other
      covenant to any other provision herein or in any other document and such
      omission to comply shall not constitute a default or an Event of Default
      under Section 5.1(4) or 5.1(9) or otherwise, as the case may be, but,
      except as specified above, the remainder of this Indenture and such
      Securities and Coupons appertaining thereto shall be unaffected thereby.

            (4) The following shall be the conditions to application of clause
      (2) or (3) of this Section 4.2 to any Outstanding Securities of or within
      a series and any Coupons appertaining thereto:

                  (a) The Company shall irrevocably have deposited or caused to
            be deposited with the Trustee (or another trustee satisfying the
            requirements of Section 6.7 who shall agree to comply with the
            provisions of this Section 4.2 applicable to it) as trust funds in
            trust for the purpose of making the following payments, specifically
            pledged as security for, and dedicated solely to, the benefit of the
            Holders of such Securities and any Coupons appertaining thereto, (1)
            an


                                       36
<PAGE>

            amount in Dollars or in such Foreign Currency in which such
            Securities and any Coupons appertaining thereto are then specified
            as payable at Stated Maturity, or (2) Government Obligations
            applicable to such Securities and Coupons appertaining thereto
            (determined on the basis of the Currency in which such Securities
            and Coupons appertaining thereto are then specified as payable at
            Stated Maturity) which through the scheduled payment of principal
            and interest in respect thereof in accordance with their terms will
            provide, not later than one day before the due date of any payment
            of principal of (and premium, if any) and interest, if any, on such
            Securities and any Coupons appertaining thereto, money in an amount,
            or (3) a combination thereof, in any case, in an amount, sufficient,
            without consideration of any reinvestment of such principal and
            interest, in the opinion of a nationally recognized firm of
            independent public accountants expressed in a written certification
            thereof delivered to the Trustee, to pay and discharge, and which
            shall be applied by the Trustee (or other qualifying trustee) to pay
            and discharge, (y) the principal of (and premium, if any) and
            interest, if any, on such Outstanding Securities and any Coupons
            appertaining thereto at the Stated Maturity of such principal or
            installment of principal or premium or interest and (z) any
            mandatory sinking fund payments or analogous payments applicable to
            such Outstanding Securities and any Coupons appertaining thereto on
            the days on which such payments are due and payable in accordance
            with the terms of this Indenture and of such Securities and any
            Coupons appertaining thereto.

                  (b) Such defeasance or covenant defeasance shall not result in
            a breach or violation of, or constitute a default under, this
            Indenture or any other material agreement or instrument to which the
            Company is a party or by which it is bound.

                  (c) No Event of Default or event which with notice or lapse of
            time or both would become an Event of Default with respect to such
            Securities and any Coupons appertaining thereto shall have occurred
            and be continuing on the date of such deposit and, with respect to
            defeasance only, at any time during the period ending on the 123rd
            day after the date of such deposit (it being understood that this
            condition shall not be deemed satisfied until the expiration of such
            period).

                  (d) In the case of an election under clause (2) of this
            Section 4.2, the Company shall have delivered to the Trustee an
            Opinion of Counsel stating that (i) the Company has received from
            the Internal Revenue Service a letter ruling, or there has been
            published by the Internal Revenue Service a Revenue Ruling, or (ii)
            since the date of execution of this Indenture, there has been a
            change in the applicable Federal income tax law, in either case to
            the effect that, and based thereon such opinion shall confirm that,
            the Holders of such Outstanding Securities and any Coupons
            appertaining thereto will not recognize income, gain or loss for
            Federal income tax purposes as a result of such defeasance and will
            be subject to Federal income tax on the same amounts, in the same
            manner and at the same times as would have been the case if such
            defeasance had not occurred.


                                       37
<PAGE>

                  (e) In the case of an election under clause (3) of this
            Section 4.2, the Company shall have delivered to the Trustee an
            Opinion of Counsel to the effect that the Holders of such
            Outstanding Securities and any Coupons appertaining thereto will not
            recognize income, gain or loss for Federal income tax purposes as a
            result of such covenant defeasance and will be subject to Federal
            income tax on the same amounts, in the same manner and at the same
            times as would have been the case if such covenant defeasance had
            not occurred.

                  (f) The Company shall have delivered to the Trustee an Opinion
            of Counsel to the effect that, after the 123rd day after the date of
            deposit, all money and Government Obligations (or other property as
            may be provided pursuant to Section 3.1) (including the proceeds
            thereof) deposited or caused to be deposited with the Trustee (or
            other qualifying trustee) pursuant to this clause (4) to be held in
            trust will not be subject to any case or proceeding (whether
            voluntary or involuntary) in respect of the Company under any
            Federal or State bankruptcy, insolvency, reorganization or other
            similar law, or any decree or order for relief in respect of the
            Company issued in connection therewith.

                  (g) The Company shall have delivered to the Trustee an
            Officer's Certificate and an Opinion of Counsel, each stating that
            all conditions precedent to the defeasance or covenant defeasance
            under clause (2) or (3) of this Section 4.2 (as the case may be)
            have been complied with.

                  (h) Notwithstanding any other provisions of this Section
            4.2(4), such defeasance or covenant defeasance shall be effected in
            compliance with any additional or substitute terms, conditions or
            limitations which may be imposed on the Company in connection
            therewith pursuant to Section 3.1.

            (5) Unless otherwise specified in or pursuant to this Indenture or
      any Security, if, after a deposit referred to in Section 4.2(4)(a) has
      been made, (a) the Holder of a Security in respect of which such deposit
      was made is entitled to, and does, elect pursuant to Section 3.1 or the
      terms of such Security to receive payment in a Currency other than that in
      which the deposit pursuant to Section 4.2(4)(a) has been made in respect
      of such Security, or (b) a Conversion Event occurs in respect of the
      Foreign Currency in which the deposit pursuant to Section 4.2(4)(a) has
      been made, the indebtedness represented by such Security and any Coupons
      appertaining thereto shall be deemed to have been, and will be, fully
      discharged and satisfied through the payment of the principal of (and
      premium, if any), and interest, if any, on, and Additional Amounts, if
      any, with respect to, such Security as the same becomes due out of the
      proceeds yielded by converting (from time to time as specified below in
      the case of any such election) the amount or other property deposited in
      respect of such Security into the Currency in which such Security becomes
      payable as a result of such election or Conversion Event based on (x) in
      the case of payments made pursuant to clause (a) above, the applicable
      market exchange rate for such Currency in effect on the second Business
      Day prior to each payment date, or (y) with respect to a Conversion Event,
      the applicable market exchange rate for such Foreign Currency in effect
      (as nearly as feasible) at the time of the Conversion Event.


                                       38
<PAGE>

      The Company shall pay and indemnify the Trustee (or other qualifying
trustee, collectively for purposes of this Section 4.2(5) and Section 4.3, the
"Trustee") against any tax, fee or other charge, imposed on or assessed against
the Government Obligations deposited pursuant to this Section 4.2 or the
principal or interest received in respect thereof other than any such tax, fee
or other charge which by law is for the account of the Holders of such
Outstanding Securities and any Coupons appertaining thereto.

      Anything in this Section 4.2 to the contrary notwithstanding, the Trustee
shall deliver or pay to the Company from time to time upon Company Request any
money or Government Obligations (or other property and any proceeds therefrom)
held by it as provided in clause (4) of this Section 4.2 which, in the opinion
of a nationally recognized firm of independent public accountants expressed in a
written certification thereof delivered to the Trustee, are in excess of the
amount thereof which would then be required to be deposited to effect a
defeasance or covenant defeasance, as applicable, in accordance with this
Section 4.2.

      Section 4.3. Application of Trust Money.

      Subject to the provisions of the last paragraph of Section 10.3, all money
and Government Obligations (or other property as may be provided pursuant to
Section 3.1) (including the proceeds thereof) deposited with the Trustee
pursuant to Section 4.1 or 4.2 in respect of any Outstanding Securities of any
series and any Coupons appertaining thereto shall be held in trust and applied
by the Trustee, in accordance with the provisions of such Securities and any
Coupons appertaining thereto and this Indenture, to the payment, either directly
or through any Paying Agent (including the Company acting as its own Paying
Agent) as the Trustee may determine, to the Holders of such Securities and any
Coupons appertaining thereto of all sums due and to become due thereon in
respect of principal (and premium, if any) and interest and Additional Amounts,
if any; but such money and Government Obligations need not be segregated from
other funds except to the extent required by law.

      covenant or warranty a default in the performance or the breach of which
      is elsewhere in this Section specifically dealt with or which has been
      expressly included in this Indenture solely for the benefit of a series of

      Indebtedness now exists or shall hereafter be created or incurred, shall
      happen and shall consist of default in the payment of more than
      $50,000,000 in principal amount of such Indebtedness at the maturity
      thereof (after giving effect to any applicable grace period) or shall
      result in such Indebtedness in principal amount in excess of $50,000,000
      becoming or being declared due and payable prior to the date on which it
      would otherwise become due and payable, and such default shall not be
      cured or such acceleration shall not be rescinded or annulled within a
      period of 30 days after there shall have been given, by registered or

      Outstanding Securities of such series, a written notice specifying such

            an involuntary proceeding under any applicable bankruptcy,
            insolvency, reorganization (other than a reorganization under a
            foreign law that does not relate


                                       40

            to insolvency) or other similar law and such decree or order shall

                  (b) a decree or order adjudging the Company to be insolvent,

            and such decree or order shall remain unstayed and in effect for a
            period of 60 consecutive days; or

      insolvent or the consent by the Company to the entry of a decree or order
      for relief in an involuntary proceeding under any applicable bankruptcy,
      insolvency, reorganization or other similar law or to the commencement of
      any insolvency proceedings against it, or the filing by the Company of a
      petition or answer or consent seeking reorganization, arrangement,
      adjustment or composition of the Company or relief under any applicable
      law, or the consent by the Company to the filing of such petition or to
      the appointment of or taking possession by a custodian, receiver,
      liquidator, assignee, trustee or similar official of the Company or any
      substantial part of the property of the Company or the making by the
      Company of an assignment for the benefit of creditors, or the taking of
      corporate action by the Company in furtherance of any such action; or

            (9) any other Event of Default provided in or pursuant to this
      Indenture with respect to Securities of such series.

      Section 5.2. Acceleration of Maturity; Rescission and Annulment.

      If an Event of Default with respect to Securities of any series at the
time Outstanding (other than an Event of Default specified in clause (7) or (8)
of Section 5.1) occurs and is continuing, then the Trustee or the Holders of not
less than 25% in principal amount of the Outstanding Securities of such series
may declare the principal of all the Securities of such series, or such lesser
amount as may be provided for in the Securities of such series, to be due and
payable immediately, by a notice in writing to the Company (and to the Trustee
if given by the Holders), and upon any such declaration such principal or such
lesser amount shall become immediately due and payable.

      If an Event of Default specified in clause (7) or (8) of Section 5.1
occurs, all unpaid principal of and accrued interest on the Outstanding
Securities of that series (or such lesser amount as may be provided for in the
Securities of such series) shall ipso facto become and be


                                       41
<PAGE>

immediately due and payable without any declaration or other act on the part of
the Trustee or any Holder of any Security of that series.

      At any time after a declaration of acceleration with respect to the
Securities of any series has been made and before a judgment or decree for
payment of the money due has been obtained by the Trustee as hereinafter in this
Article provided, the Holders of not less than a majority in principal amount of
the Outstanding Securities of such series, by written notice to the Company and
the Trustee, may rescind and annul such declaration and its consequences if

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

                  (a) all overdue installments of any interest on and Additional
            Amounts with respect to all Securities of such series and any Coupon
            appertaining thereto,

                  (b) the principal of and any premium on any Securities of such
            series which have become due otherwise than by such declaration of
            acceleration and interest thereon and any Additional Amounts with

            (2) all Events of Default with respect to Securities of such series,
      other than the non-payment of the principal of, any premium and interest
      on, and any Additional Amounts with respect to Securities of such series
      which shall have become due solely by such declaration of acceleration,
      shall have been cured or waived as provided in Section 5.13.

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

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

      The Company covenants that if

            (1) default is made in the payment of any installment of interest on
      or any Additional Amounts with respect to any Security or any Coupon
      appertaining thereto when such interest or Additional Amounts shall have
      become due and payable and such default continues for a period of 30 days,

<PAGE>

            (2) default is made in the payment of the principal of or any
      premium on any Security or any Additional Amounts with respect thereto at
      their Maturity,

the Company shall, upon demand of the Trustee, pay to the Trustee, for the
benefit of the Holders of such Securities and any Coupons appertaining thereto,
the whole amount of money then due and payable with respect to such Securities
and any Coupons appertaining thereto, with interest upon the overdue principal,
any premium and, to the extent that payment of such interest shall be legally
enforceable, upon any overdue installments of interest and Additional Amounts at
the rate or rates borne by or provided for in such Securities, and, in addition
thereto, such further amount of money as shall be sufficient to cover the costs
and expenses of collection, including the reasonable compensation, expenses,

amounts due to the Trustee under Section 6.6.

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

      If an Event of Default with respect to Securities of any series occurs and
is continuing, the Trustee may in its discretion proceed to protect and enforce
its rights and the rights of the Holders of Securities of such series and any
Coupons appertaining thereto 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 such Securities or in aid of the exercise of any power granted
herein or therein, or to enforce any other proper remedy.

      Section 5.4. Trustee May File Proofs of Claim.

      In case of the pendency of any receivership, insolvency, liquidation,
bankruptcy, reorganization, arrangement, adjustment, composition or other
judicial proceeding relative to the Company or any other obligor upon the
Securities of any series or the property of the Company or such other obligor or
their creditors, the Trustee (irrespective of whether the principal of the
Securities shall then be due and payable as therein expressed or by declaration
or otherwise and irrespective of whether the Trustee shall have made any demand
on the Company for the payment of any overdue principal, premium, interest or
Additional Amounts) shall be entitled and empowered, by intervention in such
proceeding or otherwise,

            (1) to file and prove a claim for the whole amount, or such lesser
      amount as may be provided for in the Securities of any applicable series,
      of the principal and any premium, interest and Additional Amounts owing
      and unpaid in respect of the Securities and any Coupons appertaining
      thereto and to file such other papers or documents as may be necessary or
      advisable in order to have the claims of the Trustee (including any claim
      for the reasonable compensation, expenses, disbursements and advances of
      the Trustee,


                                       43
<PAGE>

      its agents or counsel) and of the Holders of Securities or any Coupons
      appertaining thereto allowed in such judicial proceeding, and

            (2) to collect and receive any monies 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 of Securities or any Coupons 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 of Securities or any Coupons, to pay to the Trustee any
amount due to 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 6.6.

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

      Section 5.5. Trustee May Enforce Claims without Possession of Securities
or Coupons.

      All rights of action and claims under this Indenture or any of the
Securities or Coupons may be prosecuted and enforced by the Trustee without the
possession of any of the Securities or Coupons or the production thereof in any
proceeding relating thereto, and any such proceeding instituted by the Trustee
shall be brought in its own name as trustee of an express trust, and any
recovery or judgment, after provision for the payment of the reasonable
compensation, expenses, disbursements and advances of the Trustee, its agents
and counsel, shall be for the ratable benefit of each and every Holder of the
Securities or Coupons in respect of which such judgment has been recovered.

Coupons, or both, as the case may be, and the notation thereon of the payment if

      Additional Amounts in respect of which or for the benefit of which such
      money has been collected, ratably, without preference or priority of any
      kind, according to the aggregate amounts due and payable on such
      Securities and Coupons for principal and any premium, interest and
      Additional Amounts, respectively;


                                       44

      thereto.

      Section 5.7. Limitations on Suits.

      No Holder of any Security of any series or any Coupons appertaining
thereto shall have any right to institute any proceeding, judicial or otherwise,
with respect to this Indenture, or for the appointment of a receiver or trustee,
or for any other remedy hereunder, unless

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

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

            (3) such Holder or Holders have offered to the Trustee such
      indemnity as is reasonably satisfactory to it against the costs, expenses
      and liabilities to be incurred in compliance with such request;

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

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

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

      Section 5.8. Unconditional Right of Holders to Receive Principal and any
Premium, Interest and Additional Amounts.

      Notwithstanding any other provision in this Indenture, the Holder of any
Security or Coupon shall have the right, which is absolute and unconditional, to
receive payment of the principal of, any premium and (subject to Sections 3.5
and 3.7) interest on, and any Additional Amounts with respect to such Security
or payment of such Coupon, as the case may be, on the respective Stated Maturity
or Maturities therefor specified in such Security or Coupon (or, in the case of
redemption, on the Redemption Date or, in the case of repayment at the option of
such Holder if provided in or pursuant to this Indenture, on the date such
repayment is due) and to institute suit for the enforcement of any such payment,
and such right shall not be impaired without the consent of such Holder.

      Section 5.9. Restoration of Rights and Remedies.

      If the Trustee or any Holder of a Security or a Coupon 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 the Company, the Trustee and each such Holder shall, subject to any
determination in such proceeding, be restored severally and respectively to
their former positions hereunder, and thereafter all rights and remedies of the
Trustee and each such Holder shall continue as though no such proceeding had
been instituted.

      Section 5.10. Rights and Remedies Cumulative.

      Except as otherwise provided with respect to the replacement or payment of
mutilated, destroyed, lost or stolen Securities or Coupons in the last paragraph
of Section 3.6, no right or remedy herein conferred upon or reserved to the
Trustee or to each and every Holder of a Security or a Coupon is intended to be
exclusive of any other right or remedy, and every right and remedy, to the
extent permitted by law, shall 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, to the extent permitted by law, prevent the
concurrent assertion or employment of any other appropriate right or remedy.

      Section 5.11. Delay or Omission Not Waiver.

      No delay or omission of the Trustee or of any Holder of any Security or
Coupon to exercise any right or remedy accruing upon any Event of Default shall
impair any such right or remedy or constitute a waiver of any such Event of
Default or an acquiescence therein. Every right and remedy given by this Article
or by law to the Trustee or to any Holder of a Security or a Coupon may be
exercised from time to time, and as often as may be deemed expedient, by the
Trustee or by such Holder, as the case may be.

      Section 5.12. Control by Holders of Securities.

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

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

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

            (3) such direction is not unduly prejudicial to the rights of the
      other Holders of Securities of such series not joining in such action.

      Section 5.13. Waiver of Past Defaults.

      The Holders of not less than a majority in principal amount of the
Outstanding Securities of any series on behalf of the Holders of all the
Securities of such series and any Coupons appertaining thereto may waive any
past default hereunder with respect to such series and its consequences, except
a default

            (1) in the payment of the principal of, any premium or interest on,
      or any Additional Amounts with respect to, any Security of such series or
      any Coupons appertaining thereto, or

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

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

      Section 5.14. Waiver of Usury, Stay or Extension Laws.

      The Company covenants that (to the extent that it may lawfully do so) it
will not at any time insist upon, or plead, or in any manner whatsoever claim or
take the benefit or advantage of, any usury, stay or extension law wherever
enacted, now or at any time hereafter in force, which may affect the covenants
or the performance of this Indenture; and the Company expressly waives (to the
extent that it may lawfully do so) 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 5.15. Undertaking for Costs

      All parties to this Indenture agree, and each Holder of any Security by
his acceptance thereof shall be deemed to have agreed, that any court may in its
discretion require, in any suit for the enforcement of any right or remedy under
this Indenture, or in any suit against the Trustee for any action taken or
omitted by it as Trustee, the filing by any party litigant in such suit of any
undertaking to pay the costs of such suit, and that such court may in its
discretion assess reasonable costs, including reasonable attorneys' fees,
against any party litigant in such suit having due regard to the merits and good
faith of the claims or defenses made by such party litigant; but the provisions
of this Section 5.15 shall not apply to any suit instituted by the Trustee, to
any suit instituted by any Holder, or group of Holders, holding in the aggregate
more than 10% in principal amount of Outstanding Securities of any series, or to
any suit instituted by any Holder for the enforcement of the payment of the
principal of (or premium, if any) or interest, if any, on or Additional Amounts,
if any, with respect to any Security on or after the respective Stated
Maturities expressed in such Security (or, in the case of redemption, on or
after the Redemption Date, and, in the case of repayment, on or after the date
for repayment) or for the enforcement of the right, if any, to convert or
exchange any Security into Common Stock or other securities in accordance with
its terms.

      absence of bad faith on its part, rely upon an Officer's Certificate;

            (4) the Trustee may consult with counsel and the written advice of
      such counsel or any Opinion of Counsel shall be full and complete

      rights or powers vested in it by or pursuant to this Indenture at the
      request or direction of any of the Holders of Securities of any series or
      any Coupons appertaining thereto pursuant to this Indenture, unless such
      Holders shall have offered to the Trustee such security or indemnity as is
      reasonably satisfactory to it against the costs, expenses and liabilities
      which might be incurred by it in compliance with such request or
      direction;

            (6) 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, coupon or other paper or document, but the Trustee, in
      its discretion, may but shall not be obligated to 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 examine, during business hours and
      upon reasonable notice, the books, records and premises of the Company,
      personally or by agent or attorney;

            (8) the Trustee shall not be liable for any action taken or error of

      negligent, acted in bad faith or engaged in willful misconduct;

            (9) the Authenticating Agent, Paying Agent, and Security Registrar
      shall have the same protections as the Trustee set forth hereunder; and

            (10) the Trustee shall not be liable with respect to any action
      taken, suffered or omitted to be taken by it in good faith in accordance

      proceeding for any remedy available to the Trustee, or exercising any
      trust or power conferred upon the Trustee, under this Indenture or any
      Securities, unless it shall be proved that, in connection with any such
      action taken, suffered or omitted or any such act, the Trustee was
      negligent, acted in bad faith or engaged in willful misconduct.

provided, however, that, except in the case of a default in the payment of the
principal of (or premium, if any), or interest, if any, on, or Additional
Amounts or any sinking fund or purchase fund installment with respect to, any
Security of such series, the Trustee shall be protected in withholding such
notice if and so long as the board of directors, the executive committee or a
trust committee of directors and/or Responsible Officers of the Trustee in good
faith determine that the withholding of such notice is in the best interest of
the Holders of Securities and Coupons of such series; and provided, further,
that in the case of any default of the character specified in Section 5.1(5)
with respect to Securities of such series, no such notice to Holders shall be
given until at least 30 days after the occurrence thereof. For the purpose of
this Section, the term "default" means any event which is, or after notice or
lapse of time or both would become, an Event of Default with respect to
Securities of such series.

      Section 6.3. Not Responsible for Recitals or Issuance of Securities.

certificate of authentication, and in any Coupons shall be taken as the
statements of the Company and neither the Trustee nor any Authenticating Agent
assumes any responsibility for their correctness. The Trustee makes no
representations as to the validity or sufficiency of this Indenture or of the
Securities or the Coupons, except that the Trustee represents that it is duly
authorized to execute


                                       49

and deliver this Indenture, authenticate the Securities and perform its
obligations hereunder and that the statements made by it in a Statement of
Eligibility on Form T-1 supplied to the Company are true and accurate, subject
to the qualifications set forth therein. Neither the Trustee nor any
Authenticating Agent shall be accountable for the use or application by the
Company of the Securities or the proceeds thereof.

      Section 6.4. May Hold Securities.

      The Trustee, any Authenticating Agent, any Paying Agent, any Security
Registrar or any other Person that may be an agent of the Trustee or the
Company, in its individual or any other capacity, may become the owner or
pledgee of Securities or Coupons and, subject to Sections 310(b) and 311 of the
Trust Indenture Act, may otherwise deal with the Company with the same rights it
would have if it were not the Trustee, Authenticating Agent, Paying Agent,
Security Registrar or such other Person.

      Section 6.5. Money Held in Trust.

      Except as provided in Section 4.3 and Section 10.3, money held by the
Trustee in trust hereunder need not be segregated from other funds except to the
extent required by law and shall be held uninvested. The Trustee shall be under
no liability for interest on any money received by it hereunder except as
otherwise agreed to in writing with the Company.

      Section 6.6. Compensation and Reimbursement.

      The Company agrees:

            (1) to pay to the Trustee from time to time reasonable compensation
      for all services rendered by the Trustee hereunder (which compensation
      shall not be limited by any provision of law in regard to the compensation
      of a trustee of an express trust);

            (2) except as otherwise expressly provided herein, to reimburse the
      Trustee upon its request for all reasonable expenses, disbursements and
      advances incurred or made by the Trustee in accordance with any provision
      of this Indenture or arising out of or in connection with the acceptance
      or administration of the trust or trusts hereunder (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 the Trustee's negligence or bad faith; and

            (3) to indemnify the Trustee and its agents, officers, directors and
      employees for, and to hold them harmless against, any loss, liability or
      expense incurred without negligence or bad faith on their part, arising
      out of or in connection with the acceptance or administration of the trust
      or trusts hereunder, including the costs and expenses of defending
      themselves against any claim or liability in connection with the exercise
      or performance of any of their powers or duties hereunder, except to the
      extent that any such loss, liability or expense was due to the Trustee's
      negligence or bad faith.

      As security for the performance of the obligations of the Company under
this Section, the Trustee shall have a lien prior to the Securities of any
series upon all property and funds held or


                                       50
<PAGE>

collected by the Trustee as such, except funds held in trust for the payment of
principal of, and premium or interest on or any Additional Amounts with respect
to Securities or any Coupons appertaining thereto.

      To the extent permitted by law, any compensation or expense incurred by
the Trustee after a default specified in or pursuant to Section 5.1 is intended
to constitute an expense of administration under any then applicable bankruptcy
or insolvency law. "Trustee" for purposes of this Section 6.6 shall include any
predecessor Trustee but the negligence or bad faith of any Trustee shall not
affect the rights of any other Trustee under this Section 6.6.

      The provisions of this Section 6.6 shall survive the satisfaction and
discharge of this Indenture or the earlier resignation or removal of the Trustee
and shall apply with equal force and effect to the Trustee in its capacity as
Authenticating Agent, Paying Agent or Security Registrar.

      Section 6.7. Corporate Trustee Required; Eligibility.

      There shall at all times be a Trustee hereunder that is a Corporation

            (2) The Trustee may resign at any time with respect to the
      Securities of one or more series by giving written notice thereof to the
      Company. If the instrument of acceptance by a successor Trustee required

      after the giving of such notice of resignation, the resigning Trustee may
      petition any court of competent jurisdiction for the appointment of a
      successor Trustee with respect to such series.

            (3) The Trustee may be removed at any time with respect to the
      Securities of any series by Act of the Holders of a majority in principal
      amount of the Outstanding Securities of such series, delivered to the
      Trustee and the Company.

            (4) If at any time:

            (a) the Trustee shall fail to comply with the obligations imposed
      upon it under Section 310(b) of the Trust Indenture Act with respect to

                                       51
<PAGE>

      written request therefor by the Company or any Holder of a Security of
      such series who has been a bona fide Holder of a Security of such series
      for at least six months, or

            (b) the Trustee shall cease to be eligible under Section 6.7 and
      shall fail to resign after written request therefor by the Company or any
      such Holder, or

            (c) the Trustee shall become incapable of acting or shall be
      adjudged a bankrupt or insolvent or a receiver of the Trustee or of its
      property shall be appointed or any public officer shall take charge or
      control of the Trustee or of its property or affairs for the purpose of
      rehabilitation, conservation or liquidation,

then, in any such case, (i) the Company, by or pursuant to a Board Resolution,
may remove the Trustee with respect to all Securities or the Securities of such
series, or (ii) subject to Section 315(e) of the Trust Indenture Act, any Holder
of a Security who has been a bona fide Holder of a Security of such series for
at least six months may, on behalf of himself and all others similarly situated,
petition any court of competent jurisdiction for the removal of the Trustee with
respect to all Securities of such series and the appointment of a successor
Trustee or Trustees.

            (5) If the Trustee shall resign, be removed or become incapable of
      acting, or if a vacancy shall occur in the office of Trustee for any
      cause, with respect to the Securities of one or more series, the Company,
      by or pursuant to a Board Resolution, shall promptly appoint a successor
      Trustee or Trustees with respect to the Securities of such series (it
      being understood that any such successor Trustee may be appointed with
      respect to the Securities of one or more or all of such series and that at
      any time there shall be only one Trustee with respect to the Securities of
      any particular series) and shall comply with the applicable requirements
      of Section 6.9. If, within one year after such resignation, removal or
      incapacity, or the occurrence of such vacancy, a successor Trustee with
      respect to the Securities of any series shall be appointed by Act of the
      Holders of a majority in principal amount of the Outstanding Securities of
      such series delivered to the Company and the retiring Trustee, the
      successor Trustee so appointed shall, forthwith upon its acceptance of
      such appointment in accordance with the applicable requirements of Section
      6.9, become the successor Trustee with respect to the Securities of such
      series and to that extent supersede the successor Trustee appointed by the
      Company. If no successor Trustee with respect to the Securities of any
      series shall have been so appointed by the Company or the Holders of
      Securities and accepted appointment in the manner required by Section 6.9,
      any Holder of a Security who has been a bona fide Holder of a Security of
      such series for at least six months may, on behalf of himself and all
      others similarly situated, petition any court of competent jurisdiction
      for the appointment of a successor Trustee with respect to the Securities
      of such series.

            (6) The Company shall give notice of each resignation and each
      removal of the Trustee with respect to the Securities of any series and
      each appointment of a successor Trustee with respect to the Securities of
      any series by mailing written notice of such event by first-class mail,
      postage prepaid, to the Holders of Registered Securities, if any, of such
      series as their names and addresses appear in the Security Register and,
      if Securities of such series are issued as Bearer Securities, by
      publishing notice of such event once in an Authorized Newspaper in each
      Place of Payment located outside the


                                       52

      United States. Each notice shall include the name of the successor Trustee
      with respect to the Securities of such series and the address of its
      Corporate Trust Office.

            (7) In no event shall any retiring Trustee be liable for the acts or
      omissions of any successor Trustee hereunder.

      Section 6.9. Acceptance of Appointment by Successor.

            (1) Upon the appointment hereunder of any successor Trustee with
      respect to all Securities, such successor Trustee so appointed shall
      execute, acknowledge and deliver to the Company and the retiring Trustee
      an instrument accepting such appointment, and thereupon the resignation or
      removal of the retiring Trustee shall become effective and such successor
      Trustee, without any further act, deed or conveyance, shall become vested
      with all the rights, powers, trusts and duties hereunder of the retiring
      Trustee; but, on the request of the Company or such successor Trustee,
      such retiring Trustee, upon payment of its charges, shall execute and
      deliver an instrument transferring to such successor Trustee all the
      rights, powers and trusts of the retiring Trustee and, subject to Section
      10.3, shall duly assign, transfer and deliver to such successor Trustee
      all property and money held by such retiring Trustee hereunder, subject
      nevertheless to its claim, if any, provided for in Section 6.6.

            (2) Upon the appointment hereunder of any successor Trustee with
      respect to the Securities of one or more (but not all) series, the
      Company, the retiring Trustee and such successor Trustee shall execute and
      deliver an indenture supplemental hereto wherein each successor Trustee
      shall accept such appointment and which (1) shall contain such provisions
      as shall be necessary or desirable to transfer and confirm to, and to vest
      in, such successor Trustee all the rights, powers, trusts and duties of
      the retiring Trustee with respect to the Securities of that or those
      series to which the appointment of such successor Trustee relates, (2) if
      the retiring Trustee is not retiring with respect to all Securities, shall
      contain such provisions as shall be deemed necessary or desirable to
      confirm that all the rights, powers, trusts and duties of the retiring
      Trustee with respect to the Securities of that or those series as to which
      the retiring Trustee is not retiring shall continue to be vested in the
      retiring Trustee, and (3) shall add to or change any of the provisions of
      this Indenture as shall be necessary to provide for or facilitate the
      administration of the trusts hereunder by more than one Trustee, it being
      understood that nothing herein or in such supplemental indenture shall
      constitute such Trustees co-trustees of the same trust, that each such
      Trustee shall be trustee of a trust or trusts hereunder separate and apart
      from any trust or trusts hereunder administered by any other such Trustee
      and that no Trustee shall be responsible for any notice given to, or
      received by, or any act or failure to act on the part of any other Trustee
      hereunder, and, upon the execution and delivery of such supplemental
      indenture, the resignation or removal of the retiring Trustee shall become
      effective to the extent provided therein, such retiring Trustee shall have
      no further responsibility for the exercise of rights and powers or for the
      performance of the duties and obligations vested in the Trustee under this
      Indenture with respect to the Securities of that or those series to which
      the appointment of such successor Trustee relates other than as
      hereinafter expressly set forth, and such successor Trustee, without any
      further act, deed or conveyance, shall become vested with all the


                                       53
<PAGE>

      rights, powers, trusts and duties of the retiring Trustee with respect to
      the Securities of that or those series to which the appointment of such
      successor Trustee relates; but, on request of the Company or such
      successor Trustee, such retiring Trustee, upon payment of its charges with
      respect to the Securities of that or those series to which the appointment
      of such successor Trustee relates and subject to Section 10.3 shall duly
      assign, transfer and deliver to such successor Trustee, to the extent
      contemplated by such supplemental indenture, the property and money held
      by such retiring Trustee hereunder with respect to the Securities of that
      or those series to which the appointment of such successor Trustee
      relates, subject to its claim, if any, provided for in Section 6.6.

            (3) Upon request of any Person appointed hereunder as a successor
      Trustee, the Company shall execute any and all instruments for more fully
      and certainly vesting in and confirming to such successor Trustee all such
      rights, powers and trusts referred to in paragraph (1) or (2) of this
      Section, as the case may be.

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

      Section 6.10. Merger, Conversion, Consolidation or Succession to Business.

      Any Corporation into which the Trustee may be merged or converted or with
which it may be consolidated, or any Corporation resulting from any merger,
conversion or consolidation to which the Trustee shall be a party, shall be the
successor of the Trustee hereunder, without the execution or filing of any paper
or any further act on the part of any of the parties hereto. In case any
Securities shall have been authenticated but not delivered by the Trustee then
in office, any successor by merger, conversion or consolidation to such
authenticating Trustee may adopt such authentication and deliver the Securities
so authenticated with the same effect as if such successor Trustee had itself
authenticated such Securities.

      Section 6.11. Appointment of Authenticating Agent.

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

      Each Authenticating Agent must be acceptable to the Company and, except as
provided in or pursuant to this Indenture, shall at all times be a corporation
that would be permitted by the Trust Indenture Act to act as trustee under an
indenture qualified under the Trust Indenture Act, is authorized under
applicable law and by its charter to act as an Authenticating Agent and has a


                                       54
<PAGE>

combined capital and surplus (computed in accordance with Section 310(a)(2) of
the Trust Indenture Act) of at least $50,000,000. If at any time an
Authenticating Agent shall cease to be eligible in accordance with the
provisions of this Section, it shall resign immediately in the manner and with
the effect specified in this Section.

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

      An Authenticating Agent may resign at any time by giving written notice
thereof to the Trustee and the Company. The Trustee may at any time terminate
the agency of an Authenticating Agent by giving written notice thereof to such
Authenticating Agent and the Company. Upon receiving such a notice of
resignation or upon such a termination, or in case at any time such
Authenticating Agent shall cease to be eligible in accordance with the
provisions of this Section, the Trustee may appoint a successor Authenticating
Agent which shall be acceptable to the Company and shall (i) mail written notice
of such appointment by first-class mail, postage prepaid, to all Holders of
Registered Securities, if any, of the series with respect to which such
Authenticating Agent shall serve, as their names and addresses appear in the
Security Register, and (ii) if Securities of the series are issued as Bearer
Securities, publish notice of such appointment at least once in an Authorized
Newspaper in the place where such successor Authenticating Agent has its
principal office if such office is located outside the United States. Any
successor Authenticating Agent, upon acceptance of its appointment hereunder,
shall become vested with all the rights, powers and duties of its predecessor
hereunder, with like effect as if originally named as an Authenticating Agent.
No successor Authenticating Agent shall be appointed unless eligible under the
provisions of this Section.

      The Company agrees to pay each Authenticating Agent from time to time
reasonable compensation for its services under this Section. If the Trustee
makes such payments, it shall be entitled to be reimbursed for such payments,
subject to the provisions of Section 6.6.

      The provisions of Sections 3.8, 6.3 and 6.4 shall be applicable to each
Authenticating Agent.

      If an Authenticating Agent is appointed with respect to one or more series
of Securities pursuant to this Section, the Securities of such series may have
endorsed thereon, in addition to or in lieu of the Trustee's certificate of
authentication, an alternate certificate of authentication in substantially the
following form:


                                       55
<PAGE>

      This is one of the Securities of the series designated herein referred to
in the within-mentioned Indenture.

                                    THE FIRST NATIONAL BANK OF CHICAGO,
                                    as Trustee

                                        Authorized Officer

      If all of the Securities of any series may not be originally issued at one
time, and if the Trustee does not have an office capable of authenticating
Securities upon original issuance located in a Place of Payment where the
Company wishes to have Securities of such series authenticated upon original
issuance, the Trustee, if so requested in writing (which writing need not be
accompanied by or contained in an Officer's Certificate by the Company), shall
appoint in accordance with this Section an Authenticating Agent having an office
in a Place of Payment designated by the Company with respect to such series of
Securities.

      Indenture as shall be necessary to provide for or facilitate the

      or any Coupons appertaining thereto in any material respect; or

            (7) to add to, delete from or revise the conditions, limitations and

      any such action shall not adversely affect the interests of any Holder of
      an Outstanding Security of such series and any Coupons appertaining
      thereto or any other Outstanding Security or Coupon in any material
      respect; or

            (10) to secure the Securities pursuant to Section 10.5 or otherwise;
      or

            (11) to make provisions with respect to conversion or exchange
      rights of Holders of Securities of any series; or

            (12) to amend or supplement any provision contained herein or in any
      supplemental indenture, provided that no such amendment or supplement
      shall materially adversely affect the interests of the Holders of any
      Securities then Outstanding.

      Section 9.2. Supplemental Indentures with Consent of Holders.

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


                                       60
<PAGE>

            (1) change the Stated Maturity of the principal of, or any premium
      or installment of interest on or any Additional Amounts with respect to,
      any Security, or reduce the principal amount thereof or the rate (or
      modify the calculation of such rate) of interest thereon or any Additional
      Amounts with respect thereto, or any premium payable upon the redemption
      thereof or otherwise, or change the obligation of the Company to pay
      Additional Amounts pursuant to Section 10.4 (except as contemplated by
      Section 8.1(1) and permitted by Section 9.1(1)), or reduce the amount of
      the principal of an Original Issue Discount Security that would be due and
      payable upon a declaration of acceleration of the Maturity thereof
      pursuant to Section 5.2 or the amount thereof provable in bankruptcy
      pursuant to Section 5.4, change the redemption provisions or adversely
      affect the right of repayment at the option of any Holder as contemplated
      by Article 13, or change the Place of Payment, Currency in which the
      principal of, any premium or interest on, or any Additional Amounts with
      respect to any Security 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, in the case of repayment at the option of the Holder, on or after the
      date for repayment), or

            (2) reduce the percentage in principal amount of the Outstanding
      Securities of any series, the consent of whose Holders is required for any
      such supplemental indenture, or the consent of whose Holders is required
      for any waiver (of compliance with certain provisions of this Indenture or
      certain defaults hereunder and their consequences) provided for in this
      Indenture, or reduce the requirements of Section 15.4 for quorum or
      voting, or

            (3) modify any of the provisions of this Section, Section 5.13 or
      Section 10.8, 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, or

            (4) make any change that adversely affects the right to convert or
      exchange any Security into or for Common Stock of the Company or other
      securities (whether or not issued by the Company), cash or property in
      accordance with its terms.

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

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

      Section 9.3. Execution of Supplemental Indentures.

      As a condition to executing, or accepting the additional trusts created
by, any supplemental indenture permitted by this Article or the modifications
thereby of the trust created by this Indenture, the Trustee shall be entitled to
receive, and (subject to Section 315 of the Trust Indenture Act) 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 and an
Officer's Certificate stating that all conditions precedent to the execution of
such supplemental indenture have been fulfilled. 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 9.4. Effect of Supplemental Indentures.

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

      Section 9.5. Reference in Securities to Supplemental Indentures.

      Securities of any series 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 Securities of any series 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 Securities of such series.

      Section 9.6. Conformity with Trust Indenture Act.

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

      Section 9.7. Notice of Supplemental Indenture.

      Promptly after the execution by the Company and the Trustee of any
supplemental indenture pursuant to Section 9.2, the Company shall transmit to
the Holders of Outstanding Securities of any series affected thereby a notice
setting forth the substance of such supplemental indenture.

                                    COVENANTS

      Section 10.1. Payment of Principal, any Premium, Interest and Additional
Amounts.

      The Company covenants and agrees for the benefit of the Holders of the
Securities of each series that it will duly and punctually pay the principal of,
any premium and interest on and any Additional Amounts with respect to the
Securities of such series in accordance with the terms thereof, any Coupons
appertaining thereto and this Indenture. Any interest due on any Bearer Security
on or before the Maturity thereof, and any Additional Amounts payable with
respect to such interest, shall be payable only upon presentation and surrender
of the Coupons appertaining thereto for such interest as they severally mature.

      Section 10.2. Maintenance of Office or Agency.

      The Company shall maintain in each Place of Payment for any series of
Securities an Office or Agency where Securities of such series (but not Bearer
Securities, except as otherwise provided below, unless such Place of Payment is
located outside the United States) may be presented or surrendered for payment,
where Securities of such series may be surrendered for registration of transfer
or exchange, where Securities of such series that are convertible or
exchangeable may be surrendered for conversion or exchange, and where notices
and demands to or upon the Company in respect of the Securities of such series
relating thereto and this Indenture may be served. If Securities of a series are
issuable as Bearer Securities, the Company shall maintain, subject to any laws
or regulations applicable thereto, an Office or Agency in a Place of Payment for
such series which is located outside the United States where Securities of such
series and any Coupons appertaining thereto may be presented and surrendered for
payment; provided, however, that if the Securities of such series are listed on
The Stock Exchange of the United Kingdom and the Republic of Ireland or the
Luxembourg Stock Exchange or any other stock exchange located outside the United
States and such stock exchange shall so require, the Company shall maintain a
Paying Agent in London, Luxembourg or any other required city located outside
the United States, as the case may be, so long as the Securities of such series
are listed on such exchange. 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, except that Bearer Securities of such
series and any Coupons appertaining thereto may be presented and surrendered for
payment at the place specified for the purpose with respect to such Securities
as provided in or pursuant to this Indenture, and the Company hereby appoints
the Trustee as its agent to receive all such presentations, surrenders, notices
and demands.

      Except as otherwise provided in or pursuant to this Indenture, no payment
of principal, premium, interest or Additional Amounts with respect to Bearer
Securities shall be made at any Office or Agency in the United States or by
check mailed to any address in the United States or by transfer to an account
maintained with a bank located in the United States; provided, however, if
amounts owing with respect to any Bearer Securities shall be payable in Dollars,
payment of


                                       63
<PAGE>

principal of, any premium or interest on and any Additional Amounts with respect
to any such Security may be made at the Corporate Trust Office of the Trustee or
any Office or Agency designated by the Company in the Borough of Manhattan, The
City of New York, if (but only if) payment of the full amount of such principal,
premium, interest or Additional Amounts at all offices outside the United States
maintained for such purpose by the Company in accordance with this Indenture is
illegal or effectively precluded by exchange controls or other similar
restrictions.

      The Company may also from time to time designate one or more other Offices
or Agencies where the Securities of one or more series 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 each Place of Payment for Securities of any series for such purposes. The
Company shall 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. Unless otherwise provided in or pursuant to this Indenture, the Company
hereby designates as the Place of Payment for each series of Securities the
Borough of Manhattan, The City of New York, and initially appoints the Corporate
Trust Office of the Trustee as the Office or Agency of the Company in the
Borough of Manhattan, The City of New York for such purpose. The Company may
subsequently appoint a different Office or Agency in the Borough of Manhattan,
The City of New York for the Securities of any series.

      Unless otherwise specified with respect to any Securities pursuant to
Section 3.1, if and so long as the Securities of any series (i) are denominated
in a Foreign Currency or (ii) may be payable in a Foreign Currency, or so long
as it is required under any other provision of this Indenture, then the Company
will maintain with respect to each such series of Securities, or as so required,
at least one exchange rate agent.

      Section 10.3. Money for Securities Payments to Be Held in Trust.

      If the Company shall at any time act as its own Paying Agent with respect
to any series of Securities, it shall, on or before each due date of the
principal of, any premium or interest on or Additional Amounts with respect to
any of the Securities of such series, segregate and hold in trust for the
benefit of the Persons entitled thereto a sum in the currency or currencies,
currency unit or units or composite currency or currencies in which the
Securities of such series are payable (except as otherwise specified pursuant to
Section 3.1 for the Securities of such series) sufficient to pay the principal
or any premium, interest or Additional Amounts so becoming due until such sums
shall be paid to such Persons or otherwise disposed of as herein provided, and
shall promptly notify the Trustee of its action or failure so to act.

      Whenever the Company shall have one or more Paying Agents for any series
of Securities, it shall, on or prior to each due date of the principal of, any
premium or interest on or any Additional Amounts with respect to any Securities
of such series, deposit with any Paying Agent a sum (in the currency or
currencies, currency unit or units or composite currency or currencies described
in the preceding paragraph) sufficient to pay the principal or any premium,
interest or Additional Amounts so becoming due, such sum to be held in trust for
the benefit of


                                       64
<PAGE>

the Persons entitled thereto, 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 shall cause each Paying Agent for any series of Securities
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 shall:

            (1) hold all sums held by it for the payment of the principal of,
      any premium or interest on or any Additional Amounts with respect to
      Securities of such series in trust for the benefit of the Persons entitled
      thereto until such sums shall be paid to such Persons or otherwise
      disposed of as provided in or pursuant to this Indenture;

            (2) give the Trustee notice of any default by the Company (or any
      other obligor upon the Securities of such series) in the making of any
      payment of principal, any premium or interest on or any Additional Amounts
      with respect to the Securities of such series; and

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

      The Company may at any time, for the purpose of obtaining the satisfaction
and discharge of this Indenture or for any other purpose, pay, or by Company
Order direct any Paying Agent to pay, to the Trustee all sums held in trust by
the Company or such Paying Agent, such sums to be held by the Trustee upon the
same terms 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 sums.

      Except as otherwise provided herein or pursuant hereto, 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, any premium or interest on or any
Additional Amounts with respect to any Security of any series or any Coupon
appertaining thereto and remaining unclaimed for two years after such principal
or any such premium or interest or any such Additional Amounts shall have 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 such
Security or any Coupon appertaining thereto shall thereafter, as an unsecured
general creditor, look only to the Company for payment thereof, and all
liability of the Trustee or such Paying Agent with respect to such trust money,
and all liability of the Company as trustee thereof, shall thereupon cease;
provided, however, that the Trustee or such Paying Agent, before being required
to make any such repayment, may at the expense of the Company cause to be
published once, in an Authorized Newspaper in each Place of Payment for such
series or to be mailed to Holders of Registered Securities of such series, or
both, notice that such money remains unclaimed and that, after a date specified
therein, which shall not be less than 30 days from the date of such publication
or mailing nor shall it be later than two years after such principal and any
premium or interest or Additional Amounts shall have become due and payable, any
unclaimed balance of such money then remaining will be repaid to the Company.

      Section 10.4. Additional Amounts.

      All payments of principal of and premium, if any, interest and any other
amounts on, or in respect of, the Securities of any series or any Coupon
appertaining thereto shall be made without withholding or deduction at source
for, or on account of, any present or future taxes, fees, duties, assessments or
governmental charges of whatever nature imposed or levied by or on behalf of the
Cayman Islands or Bermuda (each, a "taxing jurisdiction") or any political
subdivision or taxing authority thereof or therein, unless such taxes, fees,
duties, assessments or governmental charges are required to be withheld or
deducted by (i) the laws (or any regulations or ruling promulgated thereunder)
of a taxing jurisdiction or any political subdivision or taxing authority
thereof or therein or (ii) an official position regarding the application,
administration, interpretation or enforcement of any such laws, regulations or
rulings (including, without limitation, a holding by a court of competent
jurisdiction or by a taxing authority in a taxing jurisdiction or any political
subdivision thereof). If a withholding or deduction at source is required, the
Company shall, subject to certain limitations and exceptions set forth below,
pay to the Holder of any such Security or any Coupon appertaining thereto such
Additional Amounts as may be necessary so that every net payment of principal,
premium, if any, interest or any other amount made to such Holder, after such
withholding or deduction, shall not be less than the amount provided for in such
Security, any Coupons appertaining thereto and this Indenture to be then due and
payable; provided, however, that the Company shall not be required to make
payment of such Additional Amounts for or on account of:

            (1) any tax, fee, duty, assessment or governmental charge of
      whatever nature which would not have been imposed but for the fact that
      such Holder: (A) was a resident, domiciliary or national of, or engaged in
      business or maintained a permanent establishment or was physically present
      in, the relevant taxing jurisdiction or any political subdivision thereof
      or otherwise had some connection with the relevant taxing jurisdiction
      other than by reason of the mere ownership of, or receipt of payment
      under, such Security; (B) presented such Security for payment in the
      relevant taxing jurisdiction or any political subdivision thereof, unless
      such Security could not have been presented for payment elsewhere; or (C)
      presented such Security more than thirty (30) days after the date on which
      the payment in respect of such Security first became due and payable or
      provided for, whichever is later, except to the extent that the Holder
      would have been entitled to such Additional Amounts if it had presented
      such Security for payment on any day within such period of thirty (30)
      days;

            (2) any estate, inheritance, gift, sale, transfer, personal property
      or similar tax, assessment or other governmental charge;

            (3) any tax, assessment or other governmental charge that is imposed
      or withheld by reason of the failure by the Holder or the beneficial owner
      of such Security to comply with any reasonable request by the Company
      addressed to the Holder within 90 days of such request (A) to provide
      information concerning the nationality, residence or identity of the
      Holder or such beneficial owner or (B) to make any declaration or other
      similar claim or satisfy any information or reporting requirement, which,
      in the case of (A) or (B), is required or imposed by statute, treaty,
      regulation or administrative practice


                                       66
<PAGE>

      of the relevant taxing jurisdiction or any political subdivision thereof
      as a precondition to exemption from all or part of such tax, assessment or
      other governmental charge; or

            (4) any combination of items (1), (2) and (3);

nor shall Additional Amounts be paid with respect to any payment of the
principal of, or premium, if any, interest or any other amounts on, any such
Security to any Holder who is a fiduciary or partnership or other than the sole
beneficial owner of such Security to the extent such payment would be required
by the laws of the relevant taxing jurisdiction (or any political subdivision or
relevant taxing authority thereof or therein) to be included in the income for
tax purposes of a beneficiary or partner or settlor with respect to such
fiduciary or a member of such partnership or a beneficial owner who would not
have been entitled to such Additional Amounts had it been the Holder of the
Security.

      Whenever in this Indenture there is mentioned, in any context, the payment
of the principal of or any premium, interest or any other amounts on, or in
respect of, any Security of any series or any Coupon or the net proceeds
received on the sale or exchange of any Security of any series, such mention
shall be deemed to include mention of the payment of Additional Amounts provided
by the terms of such series established hereby or pursuant hereto to the extent
that, in such context, Additional Amounts are, were or would be payable in
respect thereof pursuant to such terms, and express mention of the payment of
Additional Amounts (if applicable) in any provision hereof shall not be
construed as excluding the payment of Additional Amounts in those provisions
hereof where such express mention is not made.

      Except as otherwise provided in or pursuant to this Indenture or the
Securities of the applicable series, at least 10 days prior to the first
Interest Payment Date with respect to a series of Securities (or if the
Securities of such series shall not bear interest prior to Maturity, the first
day on which a payment of principal is made), and at least 10 days prior to each
date of payment of principal or interest if there has been any change with
respect to the matters set forth in the below-mentioned Officer's Certificate,
the Company shall furnish to the Trustee and the principal Paying Agent or
Paying Agents, if other than the Trustee, an Officer's Certificate instructing
the Trustee and such Paying Agent or Paying Agents whether such payment of
principal of and premium, if any, interest or any other amounts on the
Securities of such series shall be made to Holders of Securities of such series
or the Coupons appertaining thereto without withholding for or on account of any
tax, fee, duty, assessment or other governmental charge described in this
Section 10.4. If any such withholding shall be required, then such Officer's
Certificate shall specify by taxing jurisdiction the amount, if any, required to
be withheld on such payments to such Holders of Securities or Coupons, and the
Company agrees to pay to the Trustee or such Paying Agent the Additional Amounts
required by this Section 10.4. The Company covenants to indemnify the Trustee
and any Paying Agent for, and to hold them harmless against, any loss, liability
or expense reasonably incurred without negligence or bad faith on their part
arising out of or in connection with actions taken or omitted by any of them in
reliance on any Officer's Certificate furnished pursuant to this Section 10.4.

      Section 10.5. Limitation on Liens on Stock of Designated Subsidiaries.

      So long as any Securities are Outstanding, the Company will not, nor will
it permit any Subsidiary to, create, assume, incur, guarantee or otherwise
permit to exist any Indebtedness secured by any mortgage, pledge, lien, security
interest or other encumbrance (a "Lien") upon any shares of Capital Stock of any
Designated Subsidiary (whether such shares of stock are now owned or hereafter
acquired) without effectively providing concurrently that the Securities (and,
if the Company so elects, any other Indebtedness of the Company that is not
subordinate to the Securities and with respect to which the governing
instruments require, or pursuant to which the Company is otherwise obligated, to
provide such security) shall be secured equally and ratably with such
Indebtedness for at least the time period such other Indebtedness is so secured.

      Section 10.6. Limitation on Disposition of Stock of Designated
Subsidiaries.

      So long as any Securities are outstanding and except in a transaction
otherwise governed by this Indenture, the Company will not issue, sell, assign,
transfer or otherwise dispose of any shares of, securities convertible into, or
warrants, rights or options to subscribe for or purchase shares of, Capital
Stock (other than Preferred Stock having no voting rights of any kind) of any
Designated Subsidiary, and will not permit any Designated Subsidiary to issue
(other than to the Company) any shares (other than the director's qualifying
shares) of, or securities convertible into, or warrants, rights or options to
subscribe for or purchase shares of, Capital Stock (other than Preferred Stock
having no voting rights of any kind) of any Designated Subsidiary, if, after
giving effect to any such transaction and the issuance of the maximum number of
shares issuable upon the conversion or exercise of all such convertible
securities, warrants, rights or options, the Company would own, directly or
indirectly, less than 80% of the shares of Capital Stock of such Designated
Subsidiary (other than Preferred Stock having no voting rights of any kind);
provided, however, that (i) any issuance, sale, assignment, transfer or other
disposition permitted by the Company may only be made for at least a fair market
value consideration as determined by the Board of Directors pursuant to a Board
Resolution adopted in good faith and (ii) the foregoing shall not prohibit any
such issuance or disposition of securities if required by any law or any
regulation or order of any governmental or insurance regulatory authority.
Notwithstanding the foregoing, (i) the Company may merge or consolidate any
Designated Subsidiary into or with another direct or indirect Subsidiary of the
Company the shares of Capital Stock of which the Company owns at least 80% and
(ii) the Company may, subject to the provisions of Article 8, sell, assign,
transfer or otherwise dispose of the entire Capital Stock of any Designated
Subsidiary at one time for at least a fair market value consideration as
determined by the Board of Directors pursuant to a Board Resolution adopted in
good faith.

      Section 10.7. Corporate Existence.

      Subject to Article 8, the Company shall do or cause to be done all things
necessary to preserve and keep in full force and effect its corporate existence
and that of each of its Subsidiaries and their respective rights (charter and
statutory) and franchises; provided, however, that the foregoing shall not
obligate the Company or any of its Subsidiaries to preserve any such right or
franchise if the Company or any such Subsidiary shall determine that the
preservation thereof is no longer desirable in the conduct of its business or

      Section 10.8. Waiver of Certain Covenants.

      The Company may omit in any particular instance to comply with any term,
provision or condition set forth in Sections 10.5, 10.6 or 10.7 with respect to
the Securities of any series if before the time for such compliance the Holders
of at least a majority in principal amount of the Outstanding Securities of such
series, by Act of such Holders, either shall waive such compliance in such
instance or generally shall have waived compliance with such term, provision or
condition, but no such waiver shall extend to or affect such term, provision or
condition except to the extent so expressly waived, and, until such waiver shall
become effective, the obligations of the Company and the duties of the Trustee
in respect of any such term, provision or condition shall remain in full force
and effect.

      Section 10.9. Company Statement as to Compliance; Notice of Certain
Defaults.

            (1) The Company shall deliver to the Trustee, within 120 days after
      the end of each fiscal year, a written statement (which need not be
      contained in or accompanied by an Officer's Certificate) signed by the
      principal executive officer, the principal financial officer or the
      principal accounting officer of the Company, stating that

            (a) a review of the activities of the Company during such year and
      of its performance under this Indenture has been made under his or her
      supervision, and

            (b) to the best of his or her knowledge, based on such review, (a)
      the Company has complied with all the conditions and covenants imposed on
      it under this Indenture throughout such year, or, if there has been a
      default in the fulfillment of any such condition or covenant, specifying
      each such default known to him or her and the nature and status thereof,
      and (b) no event has occurred and is continuing which is, or after notice
      or lapse of time or both would become, an Event of Default, or, if such an
      event has occurred and is continuing, specifying each such event known to
      him and the nature and status thereof.

            (2) The Company shall deliver to the Trustee, within five days after
      the occurrence thereof, written notice of any Event of Default or any
      event which after notice or lapse of time or both would become an Event of
      Default pursuant to clause (4) of Section 5.1.

            (3) The Trustee shall have no duty to monitor the Company's
      compliance with the covenants contained in this Article 10 other than as
      specifically set forth in this Section 10.9.

                            REDEMPTION OF SECURITIES

      Section 11.1. Applicability of Article.

      Redemption of Securities of any series at the option of the Company as
permitted or required by the terms of such Securities shall be made in
accordance with the terms of such Securities and (except as otherwise provided
herein or pursuant hereto) this Article.

      Section 11.2. Election to Redeem; Notice to Trustee.

      The election of the Company to redeem any Securities shall be evidenced by
or pursuant to a Board Resolution. In case of any redemption at the election of
the Company of (a) less than all of the Securities of any series or (b) all of
the Securities of any series, with the same issue date, interest rate or
formula, Stated Maturity and other terms, the Company shall, at least 60 days
prior to the Redemption Date fixed by the Company (unless a shorter notice shall
be satisfactory to the Trustee), notify the Trustee of such Redemption Date and
of the principal amount of Securities of such series to be redeemed.

      Section 11.3. Selection by Trustee of Securities to be Redeemed.

      If less than all of the Securities of any series with the same issue date,
interest rate or formula, Stated Maturity and other terms are to be redeemed,
the particular Securities to be redeemed shall be selected not more than 60 days
prior to the Redemption Date by the Trustee from the Outstanding Securities of
such series not previously called for redemption, by such method as the Trustee
shall deem fair and appropriate and which may provide for the selection for
redemption of portions of the principal amount of Registered Securities of such
series; provided, however, that no such partial redemption shall reduce the
portion of the principal amount of a Registered Security of such series not
redeemed to less than the minimum denomination for a Security of such series
established herein or pursuant hereto.

      The Trustee shall promptly notify the Company and the Security Registrar
(if other than itself) in writing of the Securities selected for redemption and,
in the case of any Securities selected for partial redemption, the principal
amount thereof to be redeemed.

      For all purposes of this Indenture, unless the context otherwise requires,
all provisions relating to the redemption of Securities shall relate, in the
case of any Securities redeemed or to be redeemed only in part, to the portion
of the principal of such Securities which has been or is to be redeemed.

      Unless otherwise specified in or pursuant to this Indenture or the
Securities of any series, if any Security selected for partial redemption is
converted into Common Stock of the Company or exchanged for other securities in
part before termination of the conversion or exchange right with respect to the
portion of the Security so selected, the converted portion of such Security
shall be deemed (so far as may be) to be the portion selected for redemption.
Securities which have been converted or exchanged during a selection of
Securities to be redeemed shall be treated by the Trustee as Outstanding for the
purpose of such selection.

      Section 11.4. Notice of Redemption.

      Notice of redemption shall be given in the manner provided in Section 1.6,
not less than 30 nor more than 60 days prior to the Redemption Date, unless a
shorter period is specified in the Securities to be redeemed, to the Holders of
Securities to be redeemed. Failure to give notice by mailing in the manner
herein provided to the Holder of any Registered Securities designated for
redemption as a whole or in part, or any defect in the notice to any such
Holder, shall not affect the validity of the proceedings for the redemption of
any other Securities or portion thereof.

      Any notice that is mailed to the Holder of any Registered Securities in
the manner herein provided shall be conclusively presumed to have been duly
given, whether or not such Holder receives the notice.

      All notices of redemption shall state:

            (1) the Redemption Date,

            (2) the Redemption Price,

            (3) if less than all Outstanding Securities of any series are to be
      redeemed, the identification (and, in the case of partial redemption, the
      principal amount) of the particular Security or Securities to be redeemed,

            (4) in case any Security is to be redeemed in part only, the notice
      which relates to such Security shall state that on and after the
      Redemption Date, upon surrender of such Security, the Holder of such
      Security will receive, without charge, a new Security or Securities of
      authorized denominations for the principal amount thereof remaining
      unredeemed,

            (5) that, on the Redemption Date, the Redemption Price shall become
      due and payable upon each such Security or portion thereof to be redeemed,
      and, if applicable, that interest thereon shall cease to accrue on and
      after said date,

            (6) the place or places where such Securities, together (in the case
      of Bearer Securities) with all Coupons appertaining thereto, if any,
      maturing after the Redemption Date, are to be surrendered for payment of
      the Redemption Price and any accrued interest and Additional Amounts
      pertaining thereto,

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

            (8) that, unless otherwise specified in such notice, Bearer
      Securities of any series, if any, surrendered for redemption must be
      accompanied by all Coupons maturing subsequent to the date fixed for
      redemption or the amount of any such missing Coupon or Coupons will be
      deducted from the Redemption Price, unless security or indemnity
      satisfactory to the Company, the Trustee and any Paying Agent is
      furnished,

            (9) if Bearer Securities of any series are to be redeemed and no
      Registered Securities of such series are to be redeemed, and if such
      Bearer Securities may be


                                       71
<PAGE>

      exchanged for Registered Securities not subject to redemption on the
      Redemption Date pursuant to Section 3.5 or otherwise, the last date, as
      determined by the Company, on which such exchanges may be made,

            (10) in the case of Securities of any series that are convertible
      into Common Stock of the Company or exchangeable for other securities, the
      conversion or exchange price or rate, the date or dates on which the right
      to convert or exchange the principal of the Securities of such series to
      be redeemed will commence or terminate and the place or places where such
      Securities may be surrendered for conversion or exchange, and

            (11) the CUSIP number or the Euroclear or the Cedel reference
      numbers of such Securities, if any (or any other numbers used by a
      Depository to identify such Securities).

      A notice of redemption published as contemplated by Section 1.6 need not
identify particular Registered Securities to be redeemed.

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

      Section 11.5. Deposit of Redemption Price.

      On or prior to any Redemption Date, the Company shall deposit, with
respect to the Securities of any series called for redemption pursuant to
Section 11.4, 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 10.3) an amount of money in the applicable Currency sufficient to pay
the Redemption Price of, and (except if the Redemption Date shall be an Interest
Payment Date, unless otherwise specified pursuant to Section 3.1 or in the
Securities of such series) any accrued interest on and Additional Amounts with
respect thereto, all such Securities or portions thereof which are to be
redeemed on that date.

      Section 11.6. Securities Payable on Redemption Date.

      Notice of redemption having been given as aforesaid, the Securities 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
interest) such Securities shall cease to bear interest and the Coupons for such
interest appertaining to any Bearer Securities so to be redeemed, except to the
extent provided below, shall be void. Upon surrender of any such Security for
redemption in accordance with said notice, together with all Coupons, if any,
appertaining thereto maturing after the Redemption Date, such Security shall be
paid by the Company at the Redemption Price, together with any accrued interest
and Additional Amounts to the Redemption Date; provided, however, that, except
as otherwise provided in or pursuant to this Indenture or the Bearer Securities
of such series, installments of interest on Bearer Securities whose Stated
Maturity is on or prior to the Redemption Date shall be payable only upon
presentation and surrender of Coupons for such interest (at an Office or Agency
located outside the United States except as otherwise provided in Section 10.2),
and provided, further, that, except as otherwise specified in


                                       72
<PAGE>

or pursuant to this Indenture or the Registered Securities of such series,
installments of interest on Registered Securities whose Stated Maturity is on or
prior to the Redemption Date shall be payable to the Holders of such Securities,
or one or more Predecessor Securities, registered as such at the close of
business on the Regular Record Dates therefor according to their terms and the
provisions of Section 3.7.

      If any Bearer Security surrendered for redemption shall not be accompanied
by all appurtenant Coupons maturing after the Redemption Date, such Security may
be paid after deducting from the Redemption Price an amount equal to the face
amount of all such missing Coupons, or the surrender of such missing Coupon or
Coupons may be waived by the Company and the Trustee if there be furnished to
them such security or indemnity as they may require to save each of them and any
Paying Agent harmless. If thereafter the Holder of such Security shall surrender
to the Trustee or any Paying Agent any such missing Coupon in respect of which a
deduction shall have been made from the Redemption Price, such Holder shall be
entitled to receive the amount so deducted; provided, however, that any interest
or Additional Amounts represented by Coupons shall be payable only upon
presentation and surrender of those Coupons at an Office or Agency for such
Security located outside of the United States except as otherwise provided in
Section 10.2.

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

      Section 11.7. Securities Redeemed in Part.

      Any Registered Security which is to be redeemed only in part shall be
surrendered at any Office or Agency for such Security (with, if the Company or
the Trustee so requires, 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 deliver to the Holder of such
Security without service charge, a new Registered Security or Securities of the
same series, containing identical terms and provisions, 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 Security so
surrendered. If a Security in global form is so surrendered, the Company shall
execute, and the Trustee shall authenticate and deliver to the U.S. Depository
or other Depository for such Security in global form as shall be specified in
the Company Order with respect thereto to the Trustee, without service charge, a
new Security in global form in a denomination equal to and in exchange for the
unredeemed portion of the principal of the Security in global form so
surrendered.

                                  SINKING FUNDS

      Section 12.1. Applicability of Article.

      The provisions of this Article shall be applicable to any sinking fund for
the retirement of Securities of a series, except as otherwise permitted or
required in or pursuant to this Indenture or any Security of such series issued
pursuant to this Indenture.

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

      Section 12.2. Satisfaction of Sinking Fund Payments with Securities.

      The Company may, in satisfaction of all or any part of any sinking fund
payment with respect to the Securities of any series to be made pursuant to the
terms of such Securities (1) deliver Outstanding Securities of such series
(other than any of such Securities previously called for redemption or any of
such Securities in respect of which cash shall have been released to the
Company), together in the case of any Bearer Securities of such series with all
unmatured Coupons appertaining thereto, and (2) apply as a credit Securities of
such series which have been redeemed either at the election of the Company
pursuant to the terms of such series of Securities or through the application of
permitted optional sinking fund payments pursuant to the terms of such
Securities, provided that such series of Securities have not been previously so
credited. Such Securities shall be received and credited for such purpose by the
Trustee at the Redemption Price specified in such Securities for redemption
through operation of the sinking fund and the amount of such sinking fund
payment shall be reduced accordingly. If, as a result of the delivery or credit
of Securities of any series in lieu of cash payments pursuant to this Section
12.2, the principal amount of Securities of such series to be redeemed in order
to satisfy the remaining sinking fund payment shall be less than $100,000, the
Trustee need not call Securities of such series for redemption, except upon
Company Request, and such cash payment shall be held by the Trustee or a Paying
Agent and applied to the next succeeding sinking fund payment, provided,
however, that the Trustee or such Paying Agent shall at the request of the
Company from time to time pay over and deliver to the Company any cash payment
so being held by the Trustee or such Paying Agent upon delivery by the Company
to the Trustee of Securities of that series purchased by the Company having an
unpaid principal amount equal to the cash payment requested to be released to
the Company.

      Section 12.3. Redemption of Securities for Sinking Fund.

      Not less than 75 days prior to each sinking fund payment date for any
series of Securities, the Company shall deliver to the Trustee an Officer's
Certificate specifying the amount of the next ensuing mandatory sinking fund
payment for that series pursuant to the terms of that series, the portion
thereof, if any, which is to be satisfied by payment of cash and the portion
thereof, if any, which is to be satisfied by delivering and crediting of
Securities of that series pursuant to Section 12.2, and the optional amount, if
any, to be added in cash to the next ensuing mandatory sinking fund payment, and
will also deliver to the Trustee any Securities to be so credited and not
theretofore delivered. If such Officer's Certificate shall specify an optional
amount to be added in cash to the next ensuing mandatory sinking fund payment,
the Company shall thereupon be obligated to pay the amount therein specified.
Not less than 60 days before each such sinking fund payment date the Trustee
shall select the Securities to be redeemed upon such sinking fund payment date
in the manner specified in Section 11.3 and cause notice of the redemption
thereof to be given in the name of and at the expense of the Company in the
manner provided in Section 11.4. Such notice having been duly given, the
redemption of such Securities shall be made upon the terms and in the manner
stated in Sections 11.6 and 11.7.

                                   ARTICLE 13

                       REPAYMENT AT THE OPTION OF HOLDERS

      Section 13.1. Applicability of Article.

      Securities of any series which are repayable at the option of the Holders
thereof before their Stated Maturity shall be repaid in accordance with the
terms of the Securities of such series. The repayment of any principal amount of
Securities pursuant to such option of the Holder to require repayment of
Securities before their Stated Maturity, for purposes of Section 3.9, shall not
operate as a payment, redemption or satisfaction of the Indebtedness represented
by such Securities unless and until the Company, at its option, shall deliver or
surrender the same to the Trustee with a directive that such Securities be
cancelled. Notwithstanding anything to the contrary contained in this Section
13.1, in connection with any repayment of Securities, the Company may arrange
for the purchase of any Securities by an agreement with one or more investment
bankers or other purchasers to purchase such Securities by paying to the Holders
of such Securities on or before the close of business on the repayment date an
amount not less than the repayment price payable by the Company on repayment of
such Securities, and the obligation of the Company to pay the repayment price of
such Securities shall be satisfied and discharged to the extent such payment is
so paid by such purchasers.

                        SECURITIES IN FOREIGN CURRENCIES

      Section 14.1. Applicability of Article.

      Whenever this Indenture provides for (i) any action by, or the
determination of any of the rights of, Holders of Securities of any series in
which not all of such Securities are denominated


                                       75
<PAGE>

in the same Currency, or (ii) any distribution to Holders of Securities, in the
absence of any provision to the contrary in the form of Security of any
particular series or pursuant to this Indenture or the Securities, any amount in
respect of any Security denominated in a Currency other than Dollars shall be
treated for any such action or distribution as that amount of Dollars that could
be obtained for such amount on such reasonable basis of exchange and as of the
record date with respect to Registered Securities of such series (if any) for
such action, determination of rights or distribution (or, if there shall be no
applicable record date, such other date reasonably proximate to the date of such
action, determination of rights or distribution) as the Company may specify in a
written notice to the Trustee.

                        MEETINGS OF HOLDERS OF SECURITIES

      Section 15.1. Purposes for Which Meetings May Be Called.

      A meeting of Holders of Securities of any series may be called at any time
and from time to time pursuant to this Article to make, give or take any
request, demand, authorization, direction, notice, consent, waiver or other Act
provided by this Indenture to be made, given or taken by Holders of Securities
of such series.

      Section 15.2. Call, Notice and Place of Meetings.

            (1) The Trustee may at any time call a meeting of Holders of
      Securities of any series for any purpose specified in Section 15.1, to be
      held at such time and at such place in the Borough of Manhattan, The City
      of New York, or, if Securities of such series have been issued in whole or
      in part as Bearer Securities, in London or in such place outside the
      United States as the Trustee shall determine. Notice of every meeting of
      Holders of Securities of any series, setting forth the time and the place
      of such meeting and in general terms the action proposed to be taken at
      such meeting, shall be given, in the manner provided in Section 1.6, not
      less than 21 nor more than 180 days prior to the date fixed for the
      meeting.

            (2) In case at any time the Company (by or pursuant to a Board
      Resolution) or the Holders of at least 10% in principal amount of the
      Outstanding Securities of any series shall have requested the Trustee to
      call a meeting of the Holders of Securities of such series for any purpose
      specified in Section 15.1, by written request setting forth in reasonable
      detail the action proposed to be taken at the meeting, and the Trustee
      shall not have mailed notice of or made the first publication of the
      notice of such meeting within 21 days after receipt of such request
      (whichever shall be required pursuant to Section 1.6) or shall not
      thereafter proceed to cause the meeting to be held as provided herein,
      then the Company or the Holders of Securities of such series in the amount
      above specified, as the case may be, may determine the time and the place
      in the Borough of Manhattan, The City of New York, or, if Securities of
      such series are to be issued as Bearer Securities, in London for such
      meeting and may call such meeting for such purposes by giving notice
      thereof as provided in clause (1) of this Section.

      Section 15.3. Persons Entitled to Vote at Meetings.

      To be entitled to vote at any meeting of Holders of Securities of any
series, a Person shall be (1) a Holder of one or more Outstanding Securities of
such series, or (2) a Person appointed by an instrument in writing as proxy for
a Holder or Holders of one or more Outstanding Securities of such series by such
Holder or Holders. The only Persons who shall be entitled to be present or to
speak at any meeting of Holders of Securities of any series shall be the Persons
entitled to vote at such meeting and their counsel, any representatives of the
Trustee and its counsel and any representatives of the Company and its counsel.

      Section 15.4. Quorum; Action.

      The Persons entitled to vote a majority in principal amount of the
Outstanding Securities of a series shall constitute a quorum for any meeting of
Holders of Securities of such series. In the absence of a quorum within 30
minutes after the time appointed for any such meeting, the meeting shall, if
convened at the request of Holders of Securities of such series, be dissolved.
In any other case the meeting may be adjourned for a period of not less than 10
days as determined by the chairman of the meeting prior to the adjournment of
such meeting. In the absence of a quorum at any reconvened meeting, such
reconvened meeting may be further adjourned for a period of not less than 10
days as determined by the chairman of the meeting prior to the adjournment of
such reconvened meeting. Notice of the reconvening of any adjourned meeting
shall be given as provided in Section 15.2(1), except that such notice need be
given only once not less than five days prior to the date on which the meeting
is scheduled to be reconvened. Notice of the reconvening of an adjourned meeting
shall state expressly the percentage, as provided above, of the principal amount
of the Outstanding Securities of such series which shall constitute a quorum.

      Except as limited by the proviso to Section 9.2, any resolution presented
to a meeting or adjourned meeting duly reconvened at which a quorum is present
as aforesaid may be adopted only by the affirmative vote of the Holders of a
majority in principal amount of the Outstanding Securities of that series;
provided, however, that, except as limited by the proviso to Section 9.2, any
resolution with respect to any request, demand, authorization, direction,
notice, consent, waiver or other Act which this Indenture expressly provides may
be made, given or taken by the Holders of a specified percentage, which is less
than a majority, in principal amount of the Outstanding Securities of a series
may be adopted at a meeting or an adjourned meeting duly reconvened and at which
a quorum is present as aforesaid by the affirmative vote of the Holders of such
specified percentage in principal amount of the Outstanding Securities of such
series.

      Any resolution passed or decision taken at any meeting of Holders of
Securities of any series duly held in accordance with this Section shall be
binding on all the Holders of Securities of such series and the Coupons
appertaining thereto, whether or not such Holders were present or represented at
the meeting.

      Section 15.5. Determination of Voting Rights; Conduct and Adjournment of
Meetings.

            (1) Notwithstanding any other provisions of this Indenture, the
      Trustee may make such reasonable regulations as it may deem advisable for
      any meeting of Holders of


                                       77
<PAGE>

      Securities of such series in regard to proof of the holding of Securities
      of such series and of the appointment of proxies and in regard to the
      appointment and duties of inspectors of votes, the submission and
      examination of proxies, certificates and other evidence of the right to
      vote, and such other matters concerning the conduct of the meeting as it
      shall deem appropriate. Except as otherwise permitted or required by any
      such regulations, the holding of Securities shall be proved in the manner
      specified in Section 1.4 and the appointment of any proxy shall be proved
      in the manner specified in Section 1.4 or by having the signature of the
      person executing the proxy witnessed or guaranteed by any trust company,
      bank or banker authorized by Section 1.4 to certify to the holding of
      Bearer Securities. Such regulations may provide that written instruments
      appointing proxies, regular on their face, may be presumed valid and
      genuine without the proof specified in Section 1.4 or other proof.

            (2) The Trustee shall, by an instrument in writing, appoint a
      temporary chairman of the meeting, unless the meeting shall have been
      called by the Company or by Holders of Securities as provided in Section
      15.2(2), in which case the Company or the Holders of Securities of the

      that no vote shall be cast or counted at any meeting in respect of any
      Security challenged as not Outstanding and ruled by the chairman of the
      meeting to be not Outstanding. The chairman of the meeting shall have no
      right to vote, except as a Holder of a Security of such series or proxy.

      meeting; and the meeting may be held as so adjourned without further
      notice.

      The vote upon any resolution submitted to any meeting of Holders of
Securities of any series shall be by written ballots on which shall be
subscribed the signatures of the Holders of Securities of such series or of
their representatives by proxy and the principal amounts and serial numbers of

permanent chairman of the meeting shall appoint two inspectors of votes who
shall count all votes cast at the meeting for or against any resolution and who

his certificate or opinion is based is erroneous. Any such Opinion of Counsel
may be based, insofar as it relates to factual matters, upon a certificate or
opinion of, or representations by, an officer or officers of the Company stating
that the information with respect


                                       11
<PAGE>

to such factual matters is in the possession of the Company, provided that such
counsel, after reasonable inquiry, has no reason to believe and does not believe
that the certificate or opinion or representations with respect to such matters
are erroneous.

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

      Section 1.4. Acts of Holders.

      (1) Any request, demand, authorization, direction, notice, consent, waiver
or other action provided by or pursuant to this Indenture to be given or taken
by Holders may be embodied in and evidenced by one or more instruments of
substantially similar tenor signed by such Holders in person or by an agent duly
appointed in writing. If, but only if, Securities of a series are issuable as
Bearer Securities, any request, demand, authorization, direction, notice,
consent, waiver or other action provided in or pursuant to this Indenture to be
given or taken by Holders of Securities of such series may, alternatively, be
embodied in and evidenced by the record of Holders of Securities of such series
voting in favor thereof, either in person or by proxies duly appointed in
writing, at any meeting of Holders of Securities of such series duly called and
held in accordance with the provisions of Article 15, or a combination of such
instruments and any such record. Except as herein otherwise expressly provided,
such action shall become effective when such instrument or instruments or record
or both are delivered to the Trustee and, where it is hereby expressly required,
to the Company. Such instrument or instruments and any such record (and the
action embodied therein and evidenced thereby) are herein sometimes referred to
as the "Act" of the Holders signing such instrument or instruments or so voting
at any such meeting. Proof of execution of any such instrument or of a writing
appointing any such agent, or of the holding by any Person of a Security, shall
be sufficient for any purpose of this Indenture and (subject to Section 315 of
the Trust Indenture Act) conclusive in favor of the Trustee and the Company and
any agent of the Trustee or the Company, if made in the manner provided in this
Section. The record of any meeting of Holders of Securities shall be proved in
the manner provided in Section 15.6.

      Without limiting the generality of this Section 1.4, unless otherwise
provided in or pursuant to this Indenture, a Holder, including a U.S. Depository
that is a Holder of a global Security, may make, give or take, by a proxy or
proxies duly appointed in writing, any request, demand, authorization,
direction, notice, consent, waiver or other Act provided in or pursuant to this
Indenture to be made, given or taken by Holders, and a U.S. Depository that is a
Holder of a global Security may provide its proxy or proxies to the beneficial
owners of interests in any such global Security through such U.S. Depository's
standing instructions and customary practices.

      The Company shall fix a record date for the purpose of determining the
Persons who are beneficial owners of interest in any permanent global Security
held by a U.S. Depository entitled under the procedures of such U.S. Depository
to make, give or take, by a proxy or proxies duly appointed in writing, any
request, demand, authorization, direction, notice, consent, waiver or other Act
provided in or pursuant to this Indenture to be made, given or taken by Holders.
If such a record date is fixed, the Holders on such record date or their duly
appointed proxy or proxies, and only such Persons, shall be entitled to make,
give or take such request, demand,


                                       12
<PAGE>

authorization, direction, notice, consent, waiver or other Act, whether or not
such Holders remain Holders after such record date. No such request, demand,
authorization, direction, notice, consent, waiver or other Act shall be valid or
effective if made, given or taken more than 90 days after such record date.

      (2) The fact and date of the execution by any Person of any such
instrument or writing referred to in this Section 1.4 may be proved in any
reasonable manner; and the Trustee may in any instance require further proof
with respect to any of the matters referred to in this Section.

      (3) The ownership, principal amount and serial numbers of Registered
Securities held by any Person, and the date of the commencement and the date of
the termination of holding the same, shall be proved by the Security Register.

      (4) The ownership, principal amount and serial numbers of Bearer
Securities held by any Person, and the date of the commencement and the date of
the termination of holding the same, may be proved by the production of such
Bearer Securities or by a certificate executed, as depositary, by any trust
company, bank, banker or other depositary reasonably acceptable to the Company,
wherever situated, if such certificate shall be deemed by the Company and the
Trustee to be satisfactory, showing that at the date therein mentioned such
Person had on deposit with such depositary, or exhibited to it, the Bearer
Securities therein described; or such facts may be proved by the certificate or
affidavit of the Person holding such Bearer Securities, if such certificate or
affidavit is deemed by the Trustee to be satisfactory. The Trustee and the
Company may assume that such ownership of any Bearer Security continues until
(i) another certificate or affidavit bearing a later date issued in respect of
the same Bearer Security is produced, or (ii) such Bearer Security is produced
to the Trustee by some other Person, or (iii) such Bearer Security is
surrendered in exchange for a Registered Security, or (iv) such Bearer Security
is no longer Outstanding. The ownership, principal amount and serial numbers of
Bearer Securities held by the Person so executing such instrument or writing and
the date of the commencement and the date of the termination of holding the same
may also be proved in any other manner which the Company and the Trustee deem
sufficient.

      (5) If the Company shall solicit from the Holders of any Registered
Securities any request, demand, authorization, direction, notice, consent,
waiver or other Act, the Company may at its option (but is not obligated to), by
Board Resolution, fix in advance a record date for the determination of Holders
of Registered Securities entitled to give such request, demand, authorization,
direction, notice, consent, waiver or other Act. If such a record date is fixed,
such request, demand, authorization, direction, notice, consent, waiver or other
Act may be given before or after such record date, but only the Holders of
Registered Securities of record at the close of business on such record date
shall be deemed to be Holders for the purpose of determining whether Holders of
the requisite proportion of Outstanding Securities have authorized or agreed or
consented to such request, demand, authorization, direction, notice, consent,
waiver or other Act, and for that purpose the Outstanding Securities shall be
computed as of such record date; provided that no such authorization, agreement
or consent by the Holders of Registered Securities shall be deemed effective
unless it shall become effective pursuant to the provisions of this Indenture
not later than six months after the record date.


                                       13
<PAGE>

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

      Section 1.5. Notices, etc. to Trustee and Company.

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

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

            (2) the Company by the Trustee or 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 the attention of its Treasurer, with a copy to the attention of its
      General Counsel, at the address of its principal office specified in the
      first paragraph of this instrument or at any other address previously
      furnished in writing to the Trustee by the Company.

      Section 1.6. Notice to Holders of Securities; Waiver.

      Except as otherwise expressly provided in or pursuant to this Indenture,
where this Indenture provides for notice to Holders of Securities of any event,

            (1) such notice shall be sufficiently given to Holders of Registered
      Securities if in writing and mailed, first-class postage prepaid, to each
      Holder of a Registered Security affected by such event, at his address as
      it appears in the Security Register, not later than the latest date, and
      not earlier than the earliest date, prescribed for the giving of such
      notice; and

            (2) such notice shall be sufficiently given to Holders of Bearer
      Securities, if any, if published in an Authorized Newspaper in The City of
      New York and, if such Securities are then listed on any stock exchange
      outside the United States, in an Authorized Newspaper in such city as the
      Company shall advise the Trustee that such stock exchange so requires, on
      a Business Day at least twice, the first such publication to be not
      earlier than the earliest date and the second such publication not later
      than the latest date prescribed for the giving of such notice.

      In any case where notice to Holders of Registered Securities is given by
mail, neither the failure to mail such notice, nor any defect in any notice so
mailed, to any particular Holder of a Registered Security shall affect the
sufficiency of such notice with respect to other Holders of Registered
Securities or the sufficiency of any notice to Holders of Bearer Securities
given as provided herein. Any notice which is mailed in the manner herein
provided shall be conclusively


                                       14
<PAGE>

presumed to have been duly given or provided. In the 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.

      In case by reason of the suspension of publication of any Authorized
Newspaper or Authorized Newspapers or by reason of any other cause it shall be
impracticable to publish any notice to Holders of Bearers Securities as provided
above, then such notification to Holders of Bearer Securities as shall be given
with the approval of the Trustee shall constitute sufficient notice to such
Holders for every purpose hereunder. Neither failure to give notice by
publication to Holders of Bearer Securities as provided above, nor any defect in
any notice so published, shall affect the sufficiency of any notice mailed to
Holders of Registered Securities as provided above.

      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 of Securities shall be filed with the Trustee, but
such filing shall not be a condition precedent to the validity of any action
taken in reliance upon such waiver.

      Section 1.7. Language of Notices.

      Any request, demand, authorization, direction, notice, consent, election
or waiver required or permitted under this Indenture shall be in the English
language, except that, if the Company so elects, any published notice may be in
an official language of the country of publication.

      Section 1.8. Conflict with Trust Indenture Act.

      If any provision hereof limits, qualifies or conflicts with any duties
under any required provision of the Trust Indenture Act imposed hereon by
Section 318(c) thereof, such required provision shall control.

      Section 1.9. Effect of Headings and Table of Contents.

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

      Section 1.10. Successors and Assigns.

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

      Section 1.11. Separability Clause.

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

      Section 1.12. Benefits of Indenture.

      Nothing in this Indenture, any Security or any Coupon, express or implied,
shall give to any Person, other than the parties hereto and holders of Senior
Indebtedness, any Security Registrar, any Paying Agent, any Authenticating Agent
and their successors hereunder and the Holders of Securities or Coupons, any
benefit or any legal or equitable right, remedy or claim under this Indenture.

      Section 1.13. Governing Law.

      This Indenture, the Securities and any Coupons shall be governed by and
construed in accordance with the laws of the State of New York applicable to
agreements made or instruments entered into and, in each case, performed in said
state.

      Section 1.14. Legal Holidays.

      Unless otherwise specified in or pursuant to this Indenture or any
Securities, in any case where any Interest Payment Date, Stated Maturity or
Maturity of any Security, or the last date on which a Holder has the right to
convert or exchange Securities of a series that are convertible or exchangeable,
shall be a Legal Holiday at any Place of Payment, then (notwithstanding any
other provision of this Indenture, any Security or any Coupon other than a
provision in any Security or Coupon that specifically states that such provision
shall apply in lieu hereof) payment need not be made at such Place of Payment on
such date, and such Securities need not be converted or exchanged on such date
but such payment may be made, and such Securities may be converted or exchanged,
on the next succeeding day that is a Business Day at such Place of Payment with
the same force and effect as if made on the Interest Payment Date or at the
Stated Maturity or Maturity or on such last day for conversion or exchange, and
no interest shall accrue on the amount payable on such date or at such time for
the period from and after such Interest Payment Date, Stated Maturity, Maturity
or last day for conversion or exchange, as the case may be, to such next
succeeding Business Day.

      Section 1.15. Counterparts.

      This Indenture may be executed in several counterparts, each of which
shall be an original and all of which shall constitute but one and the same
instrument.

      Section 1.16. Judgment Currency.

      The Company agrees, to the fullest extent that it may effectively do so
under applicable law, that (a) if for the purpose of obtaining judgment in any
court it is necessary to convert the sum due in respect of the principal of, or
premium or interest, if any, or Additional Amounts on the Securities of any
series (the "Required Currency") into a currency in which a judgment will be
rendered (the "Judgment Currency"), the rate of exchange used shall be the rate
at which in accordance with normal banking procedures the Trustee could purchase
in The City of New York the requisite amount of the Required Currency with the
Judgment Currency on the New York Banking Day preceding the day on which a final
unappealable judgment is given and (b) its obligations under this Indenture to
make payments in the Required Currency (i) shall not be discharged or satisfied
by any tender, or any recovery pursuant to any judgment (whether or not


                                       16
<PAGE>

entered in accordance with clause (a)), in any currency other than the Required
Currency, except to the extent that such tender or recovery shall result in the
actual receipt, by the payee, of the full amount of the Required Currency
expressed to be payable in respect of such payments, (ii) shall be enforceable
as an alternative or additional cause of action for the purpose of recovering in
the Required Currency the amount, if any, by which such actual receipt shall
fall short of the full amount of the Required Currency so expressed to be
payable and (iii) shall not be affected by judgment being obtained for any other
sum due under this Indenture. For purposes of the foregoing, "New York Banking
Day" means any day except a Saturday, Sunday or a legal holiday in The City of
New York or a day on which banking institutions in The City of New York are
authorized or obligated by law, regulation or executive order to be closed.

      Section 1.17. No Security Interest Created.

      Nothing in this Indenture or in any Securities, express or implied, shall
be construed to constitute a security interest under the Uniform Commercial Code
or similar legislation, as now or hereafter enacted and in effect in any
jurisdiction where property of the Company or its Subsidiaries is or may be
located.

      Section 1.18. Limitation on Individual Liability.

      No recourse under or upon any obligation, covenant or agreement contained
in this Indenture or in any Security, or for any claim based thereon or
otherwise in respect thereof, shall be had against any incorporator,
shareholder, officer or director, as such, past, present or future, of the
Company, either directly or through the Company, whether by virtue of any
constitution, statute or rule of law, or by the enforcement of any assessment or
penalty or otherwise; it being expressly understood that this Indenture and the
obligations issued hereunder are solely corporate obligations, and that no such
personal liability whatever shall attach to, or is or shall be incurred by, the
incorporators, shareholders, officers or directors, as such, of the Company, or
any of them, because of the creation of the indebtedness hereby authorized, or
under or by reason of the obligations, covenants or agreements contained in this
Indenture or in any Security or implied therefrom; and that any and all such
personal liability of every name and nature, either at common law or in equity
or by constitution or statute, of, and any and all such rights and claims
against, every such incorporator, shareholder, officer or director, as such,
because of the creation of the indebtedness hereby authorized, or under or by
reason of the obligations, covenants or agreements contained in this Indenture
or in any Security or implied therefrom, are hereby expressly waived and
released as a condition of, and as a consideration for, the execution of this
Indenture and the issuance of such Security.

      Section 1.19. Submission to Jurisdiction.

      The Company agrees that any judicial proceedings instituted in relation to
any matter arising under this Indenture, the Securities or any Coupons
appertaining thereto may be brought in any United States Federal or New York
State court sitting in the Borough of Manhattan, The City of New York, New York
to the extent that such court has subject matter jurisdiction over the
controversy and, by execution and delivery of this Indenture, the Company hereby
irrevocably accepts, generally and unconditionally, the jurisdiction of the
aforesaid courts, acknowledges their competence and irrevocably agrees to be
bound by any judgement rendered


                                       17
<PAGE>

in such proceeding. The Company also irrevocably and unconditionally waives for
the benefit of the Trustee and the Holders of the Securities and Coupons any
immunity from jurisdiction and any immunity from legal process (whether through
service or notice, attachment prior to judgement, attachment in the aid of
execution, execution or otherwise) in respect of this Indenture. The Company
hereby irrevocably designates and appoints for the benefit of the Trustee and
the Holders of the Securities and Coupons for the term of this Indenture ACE
USA, Inc., 1133 Avenue of the Americas, 32nd Floor, New York, New York 10036 as
its agent to receive on its behalf service of all process (with a copy of all
such service of process to be delivered to Peter N. Mear, General Counsel and
Secretary, ACE Limited, The ACE Building, 30 Woodbourne Avenue, Hamilton HM 08,
Bermuda) brought against it with respect to any such proceeding in any such
court in The City of New York, such service being hereby acknowledged by the
Company to be effective and binding service on it in every respect whether or
not the Company shall then be doing or shall have at any time done business in
New York. Such appointment shall be irrevocable so long as any of the Securities
or Coupons or the obligations of the Company hereunder remain outstanding until
the appointment of a successor by the Company and such successor's acceptance of
such appointment. Upon such acceptance, the Company shall notify the Trustee of
the name and address of such successor. The Company further agrees for the
benefit of the Trustee and the Holders of the Securities and the Coupons to take
any and all action, including the execution and filing of any and all such
documents and instruments, as may be necessary to continue such designation and
appointment of said ACE USA, Inc. in full force and effect so long as any of the
Securities or Coupons or the obligations of the Company hereunder shall be
outstanding. The Trustee shall not be obligated and shall have no responsibility
with respect to any failure by the Company to take any such action. Nothing
herein shall affect the right to serve process in any other manner permitted by
any law or limit the right of the Trustee or any Holder to institute proceedings
against the Company in the courts of any other jurisdiction or jurisdictions.

                                   ARTICLE 2

                                SECURITIES FORMS

      Section 2.1. Forms Generally.

      Each Registered Security, Bearer Security, Coupon and temporary or
permanent global Security issued pursuant to this Indenture shall be in the form
established by or pursuant to a Board Resolution or in one or more indentures
supplemental hereto, shall have such appropriate insertions, omissions,
substitutions and other variations as are required or permitted by or pursuant
to this Indenture or any indenture supplemental hereto and may have such
letters, numbers or other marks of identification and such legends or
endorsements placed thereon as may, consistently herewith, be determined by the
officers executing such Security or Coupon as evidenced by their execution of
such Security or Coupon.

      Unless otherwise provided in or pursuant to this Indenture or any
Securities, the Securities shall be issuable in registered form without Coupons
and shall not be issuable upon the exercise of warrants.


                                       18

                                          as Trustee

                                    By_________________________________________
                                          Authorized Officer

      Section 2.3. Securities in Global Form.

      Unless otherwise provided in or pursuant to this Indenture or any
Securities, the Securities shall not be issuable in temporary or permanent
global form. If Securities of a series shall be issuable in global form, any
such Security may provide that it or any number of such Securities shall
represent the aggregate amount of all Outstanding Securities of such series (or
such lesser amount as is permitted by the terms thereof) from time to time
endorsed thereon and may also provide that the aggregate amount of Outstanding
Securities represented thereby may from time to time be increased or reduced to
reflect exchanges. Any endorsement of any Security in global form to reflect the
amount, or any increase or decrease in the amount, or changes in the rights of
Holders, of Outstanding Securities represented thereby shall be made in such
manner and by such Person or Persons as shall be specified therein or in the
Company Order to be delivered pursuant to Section 3.3 or 3.4 with respect
thereto. Subject to the provisions of Section 3.3 and, if applicable, Section
3.4, the Trustee shall deliver and redeliver, in each case at the Company's
expense, any Security in permanent global form in the manner and upon
instructions given by the Person or Persons specified therein or in the
applicable Company Order. If a Company Order pursuant to Section 3.3 or 3.4 has
been, or simultaneously is, delivered, any instructions by the Company with
respect to a Security in global form shall be in writing but need not be
accompanied by or contained in an Officer's Certificate and need not be
accompanied by an Opinion of Counsel.

      Notwithstanding the provisions of Section 3.7, unless otherwise specified
in or pursuant to this Indenture or any Securities, payment of principal of, any
premium and interest on, and any Additional Amounts in respect of, any Security
in temporary or permanent global form shall be made to the Person or Persons
specified therein.


                                       19
<PAGE>

      Notwithstanding the provisions of Section 3.8 and except as provided in
the preceding paragraph, the Company, the Trustee and any agent of the Company
or the Trustee shall treat as the Holder of such principal amount of Outstanding
Securities represented by a global Security (i) in the case of a global Security
in registered form, the Holder of such global Security in registered form, or
(ii) in the case of a global Security in bearer form, the Person or Persons
specified pursuant to Section 3.1.

                                   ARTICLE 3

                                 THE SECURITIES

      Section 3.1. Amount Unlimited; Issuable in Series.

      The aggregate principal amount of Securities which may be authenticated
and delivered under this Indenture is unlimited. The Securities may be issued in
one or more series. The Securities of each series shall be subordinated in right
of payment to all Senior Indebtedness with respect to such series as provided in
Article 16.

      With respect to any Securities to be authenticated and delivered
hereunder, there shall be established in or pursuant to a Board Resolution and
set forth in an Officer's Certificate, or established in one or more indentures
supplemental hereto,

            (1) the title of such Securities and the series in which such
      Securities shall be included;

            (2) any limit upon the aggregate principal amount of the Securities
      of such title or the Securities of such series which may be authenticated
      and delivered under this Indenture (except for Securities authenticated
      and delivered upon registration of transfer of, or in exchange for, or in
      lieu of, other Securities of such series pursuant to Section 3.4, 3.5,
      3.6, 9.5 or 11.7, upon repayment in part of any Registered Security of
      such series pursuant to Article 13, upon surrender in part of any
      Registered Security for conversion into Common Stock of the Company or
      exchange for other securities pursuant to its terms, or pursuant to or as
      contemplated by the terms of such Securities);

            (3) if such Securities are to be issuable as Registered Securities,
      as Bearer Securities or alternatively as Bearer Securities and Registered
      Securities, and whether the Bearer Securities are to be issuable with
      Coupons, without Coupons or both, and any restrictions applicable to the
      offer, sale or delivery of the Bearer Securities and the terms, if any,
      upon which Bearer Securities may be exchanged for Registered Securities
      and vice versa;

            (4) if any of such Securities are to be issuable in global form,
      when any of such Securities are to be issuable in global form and (i)
      whether such Securities are to be issued in temporary or permanent global
      form or both, (ii) whether beneficial owners of interests in any such
      global Security may exchange such interests for Securities of the same
      series and of like tenor and of any authorized form and denomination, and
      the circumstances under which any such exchanges may occur, if other than
      in the manner


                                       20
<PAGE>

      specified in Section 3.5, and (iii) the name of the Depository or the U.S.
      Depository, as the case may be, with respect to any such global Security;

            (5) if any of such Securities are to be issuable as Bearer
      Securities or in global form, the date as of which any such Bearer
      Security or global Security shall be dated (if other than the date of
      original issuance of the first of such Securities to be issued);

            (6) if any of such Securities are to be issuable as Bearer

            (14) if other than the principal amount thereof, the portion of the
      principal amount of any of such Securities that shall be payable upon
      declaration of acceleration of the Maturity thereof pursuant to Section

      other Indebtedness of the Company in right of payment, whether such other

            (19) any deletions from, modifications of or additions to the Events
      of Default or covenants of the Company with respect to any of such

Bearer Securities of such series shall be substantially identical except as to
Currency of payments due thereunder, denomination and the rate of interest
thereon, or method of determining the rate of interest, if any, Maturity, and
the date from which interest, if any, shall accrue and except as may otherwise
be provided by the Company in or pursuant to the Board Resolution and set forth
in the Officer's Certificate or in any indenture or indentures supplemental
hereto pertaining to such series of Securities. The terms of the Securities of
any series may provide, without limitation, that the Securities shall be
authenticated and delivered by the Trustee on original issue from time to time
upon written order of persons designated in the Officer's Certificate or
supplemental indenture and that such persons are authorized to determine,
consistent with such Officer's Certificate or any applicable supplemental
indenture, such terms and conditions of the Securities of such series as are
specified in such Officer's Certificate or supplemental indenture. All
Securities of any one


                                       23
<PAGE>

series need not be issued at the same time and, unless otherwise so provided, a
series may be reopened for issuances of additional Securities of such series or
to establish additional terms of such series of Securities.

      If any of the terms of the Securities of any series shall be established
by action taken by or pursuant to a Board Resolution, the Board Resolution shall
be delivered to the Trustee at or prior to the delivery of the Officer's
Certificate setting forth the terms of such series.

      Section 3.2. Currency; Denominations.

      Unless otherwise provided in or pursuant to this Indenture, the principal
of, any premium and interest on and any Additional Amounts with respect to the
Securities shall be payable in Dollars. Unless otherwise provided in or pursuant
to this Indenture, Registered Securities denominated in Dollars shall be
issuable in registered form without Coupons in denominations of $1,000 and any
integral multiple thereof, and the Bearer Securities denominated in Dollars
shall be issuable in the denomination of $5,000. Securities not denominated in
Dollars shall be issuable in such denominations as are established with respect
to such Securities in or pursuant to this Indenture.

      Section 3.3. Execution, Authentication, Delivery and Dating.

      Securities shall be executed on behalf of the Company by its Chairman of
the Board, a Vice Chairman, its President, Chief Financial Officer, Chief
Investment Officer or Chief Accounting Officer under its corporate seal
reproduced thereon and attested by its Secretary. Coupons shall be executed on
behalf of the Company by the Chief Financial Officer or Chief Accounting Officer
of the Company. The signature of any of these officers on the Securities or any
Coupons appertaining thereto may be manual or facsimile.

      Securities and any Coupons appertaining thereto 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 Securities and Coupons or did not hold such offices at the date
of original issuance of such Securities or Coupons.

      At any time and from time to time after the execution and delivery of this
Indenture, the Company may deliver Securities, together with any Coupons
appertaining thereto, executed by the Company, to the Trustee for authentication
and, provided that the Board Resolution and Officer's Certificate or
supplemental indenture or indentures with respect to such Securities referred to
in Section 3.1 and a Company Order for the authentication and delivery of such
Securities have been delivered to the Trustee, the Trustee in accordance with
the Company Order and subject to the provisions hereof and of such Securities
shall authenticate and deliver such Securities. In authenticating such
Securities, and accepting the additional responsibilities under this Indenture
in relation to such Securities and any Coupons appertaining thereto, the Trustee
shall be entitled to receive, and (subject to Sections 315(a) through 315(d) of
the Trust Indenture Act) shall be fully protected in relying upon,

      (1) an Opinion of Counsel to the effect that:


                                       24
<PAGE>

            (a) the form or forms and terms of such Securities and Coupons, if
      any, have been established in conformity with the provisions of this
      Indenture;

            (b) all conditions precedent to the authentication and delivery of
      such Securities and Coupons, if any, appertaining thereto, have been
      complied with and that such Securities and Coupons, when completed by
      appropriate insertions, executed under the Company's corporate seal and
      attested by duly authorized officers of the Company, delivered by duly
      authorized officers of the Company to the Trustee for authentication
      pursuant to this Indenture, and authenticated and delivered by the Trustee
      and issued by the Company in the manner and subject to any conditions
      specified in such Opinion of Counsel, will constitute legally valid and
      binding obligations of the Company, enforceable against the Company in
      accordance with their terms, except as enforcement thereof may be subject
      to or limited by bankruptcy, insolvency, reorganization, moratorium,
      arrangement, fraudulent conveyance, fraudulent transfer or other similar
      laws relating to or affecting creditors' rights generally, and subject to
      general principles of equity (regardless of whether enforcement is sought
      in a proceeding in equity or at law) and will entitle the Holders thereof
      to the benefits of this Indenture; such Opinion of Counsel need express no
      opinion as to the availability of equitable remedies;

            (c) all laws and requirements in respect of the execution and
      delivery by the Company of such Securities and Coupons, if any, have been
      complied with; and

            (d) this Indenture has been qualified under the Trust Indenture Act;
      and

      (2) an Officer's Certificate stating that all conditions precedent to the
execution, authentication and delivery of such Securities and Coupons, if any,
appertaining thereto, have been complied with and that, to the best knowledge of
the Persons executing such certificate, no event which is, or after notice or
lapse of time would become, an Event of Default with respect to any of the
Securities shall have occurred and be continuing.

      If all the Securities of any series are not to be issued at one time, it
shall not be necessary to deliver an Opinion of Counsel and an Officer's
Certificate at the time of issuance of each Security, but such opinion and
certificate, with appropriate modifications, shall be delivered at or before the
time of issuance of the first Security of such series. After any such first
delivery, any separate written request by an Authorized Officer of the Company
or any person designated in writing by an Authorized Officer that the Trustee
authenticate and deliver Securities of such series for original issue will be
deemed to be a certification by the Company that all conditions precedent
provided for in this Indenture relating to authentication and delivery of such
Securities continue to have been complied with.

      The Trustee shall not be required to authenticate or to cause an
Authenticating Agent to authenticate any Securities if the issue of such
Securities pursuant to this Indenture will affect the Trustee's own rights,
duties or immunities under the Securities and this Indenture or otherwise in a
manner which is not reasonably acceptable to the Trustee or if the Trustee,
being advised by counsel, determines that such action may not lawfully be taken.


                                       25
<PAGE>

      Each Registered Security shall be dated the date of its authentication.
Each Bearer Security and any Bearer Security in global form shall be dated as of
the date specified in or pursuant to this Indenture.

      No Security or Coupon appertaining thereto shall be entitled to any
benefit under this Indenture or be valid or obligatory for any purpose, unless
there appears on such Security a certificate of authentication substantially in
the form provided for in Section 2.2 or 6.11 executed by or on behalf of the
Trustee or by the Authenticating Agent by the manual signature of one of its
authorized officers. Such certificate upon any Security shall be conclusive
evidence, and the only evidence, that such Security has been duly authenticated
and delivered hereunder. Except as permitted by Section 3.6 or 3.7, the Trustee
shall not authenticate and deliver any Bearer Security unless all Coupons
appertaining thereto then matured have been detached and cancelled.

      Section 3.4. Temporary Securities.

      Pending the preparation of definitive Securities, the Company may execute
and deliver to the Trustee and, upon Company Order, the Trustee shall
authenticate and deliver, in the manner provided in Section 3.3, temporary
Securities in lieu thereof which are printed, lithographed, typewritten,
mimeographed or otherwise produced, in any authorized denomination,
substantially of the tenor of the definitive Securities in lieu of which they
are issued, in registered form or, if authorized in or pursuant to this
Indenture, in bearer form with one or more Coupons or without Coupons and with
such appropriate insertions, omissions, substitutions and other variations as
the officers of the Company executing such Securities may determine, as
conclusively evidenced by their execution of such Securities. Such temporary
Securities may be in global form.

      Except in the case of temporary Securities in global form, which shall be
exchanged in accordance with the provisions thereof, if temporary Securities are
issued, the Company shall cause definitive Securities to be prepared without
unreasonable delay. After the preparation of definitive Securities of the same
series and containing terms and provisions that are identical to those of any
temporary Securities, such temporary Securities shall be exchangeable for such
definitive Securities upon surrender of such temporary Securities at an Office
or Agency for such Securities, without charge to any Holder thereof. Upon
surrender for cancellation of any one or more temporary Securities (accompanied
by any unmatured Coupons appertaining thereto), the Company shall execute and
the Trustee shall authenticate and deliver in exchange therefor a like principal
amount of definitive Securities of authorized denominations of the same series
and containing identical terms and provisions; provided, however, that no
definitive Bearer Security, except as provided in or pursuant to this Indenture,
shall be delivered in exchange for a temporary Registered Security; and
provided, further, that a definitive Bearer Security shall be delivered in
exchange for a temporary Bearer Security only in compliance with the conditions
set forth in or pursuant to this Indenture. Unless otherwise provided in or
pursuant to this Indenture with respect to a temporary global Security, until so
exchanged the temporary Securities of any series shall in all respects be
entitled to the same benefits under this Indenture as definitive Securities of
such series.


                                       26

      Section 3.5. Registration, Transfer and Exchange.

      With respect to the Registered Securities of each series, if any, the
Company shall cause to be kept a register (each such register being herein
sometimes referred to as the "Security Register") at an Office or Agency for
such series in which, subject to such reasonable regulations as it may
prescribe, the Company shall provide for the registration of the Registered
Securities of such series and of transfers of the Registered Securities of such
series. Such Office or Agency shall be the "Security Registrar" for that series
of Securities. Unless otherwise specified in or pursuant to this Indenture or
the Securities, the Trustee shall be the initial Security Registrar for each
series of Securities. The Company shall have the right to remove and replace
from time to time the Security Registrar for any series of Securities; provided
that no such removal or replacement shall be effective until a successor
Security Registrar with respect to such series of Securities shall have been
appointed by the Company and shall have accepted such appointment by the
Company. In the event that the Trustee shall not be or shall cease to be
Security Registrar with respect to a series of Securities, it shall have the
right to examine the Security Register for such series at all reasonable times.
There shall be only one Security Register for each series of Securities.

      Upon surrender for registration of transfer of any Registered Security of
any series at any Office or Agency for such series, the Company shall execute,
and the Trustee shall authenticate and deliver, in the name of the designated
transferee or transferees, one or more new Registered Securities of the same
series denominated as authorized in or pursuant to this Indenture, of a like
aggregate principal amount bearing a number not contemporaneously outstanding
and containing identical terms and provisions.

      At the option of the Holder, Registered Securities of any series may be
exchanged for other Registered Securities of the same series containing
identical terms and provisions, in any authorized denominations, and of a like
aggregate principal amount, upon surrender of the Securities to be exchanged at
any Office or Agency for such series. Whenever any Registered Securities are so
surrendered for exchange, the Company shall execute, and the Trustee shall
authenticate and deliver, the Registered Securities which the Holder making the
exchange is entitled to receive.

      If provided in or pursuant to this Indenture, with respect to Securities
of any series, at the option of the Holder, Bearer Securities of such series may
be exchanged for Registered Securities of such series containing identical
terms, denominated as authorized in or pursuant to this Indenture and in the
same aggregate principal amount, upon surrender of the Bearer Securities to be
exchanged at any Office or Agency for such series, with all unmatured Coupons
and all matured Coupons in default thereto appertaining. If the Holder of a
Bearer Security is unable to produce any such unmatured Coupon or Coupons or
matured Coupon or Coupons in default, such exchange may be effected if the
Bearer Securities are accompanied by payment in funds acceptable to the Company
and the Trustee in an amount equal to the face amount of such missing Coupon or
Coupons, or the surrender of such missing Coupon or Coupons may be waived by the
Company and the Trustee if there is furnished to them such security or indemnity
as they may require to save each of them and any Paying Agent harmless. If
thereafter the Holder of such Bearer Security shall surrender to any Paying
Agent any such missing Coupon in respect of which such a payment shall have been
made, such Holder shall be entitled to receive


                                       27
<PAGE>

the amount of such payment; provided, however, that, except as otherwise
provided in Section 10.2, interest represented by Coupons shall be payable only
upon presentation and surrender of those Coupons at an Office or Agency for such
series located outside the United States. Notwithstanding the foregoing, in case
a Bearer Security of any series is surrendered at any such Office or Agency for
such series in exchange for a Registered Security of such series and like tenor
after the close of business at such Office or Agency on (i) any Regular Record
Date and before the opening of business at such Office or Agency on the next
succeeding Interest Payment Date, or (ii) any Special Record Date and before the
opening of business at such Office or Agency on the related date for payment of
Defaulted Interest, such Bearer Security shall be surrendered without the Coupon
relating to such Interest Payment Date or proposed date of payment, as the case
may be (or, if such Coupon is so surrendered with such Bearer Security, such
Coupon shall be returned to the Person so surrendering the Bearer Security), and
interest or Defaulted Interest, as the case may be, shall not be payable on such
Interest Payment Date or proposed date for payment, as the case may be, in
respect of the Registered Security issued in exchange for such Bearer Security,
but shall be payable only to the Holder of such Coupon when due in accordance
with the provisions of this Indenture.

      If provided in or pursuant to this Indenture with respect to Securities of
any series, at the option of the Holder, Registered Securities of such series
may be exchanged for Bearer Securities upon such terms and conditions as may be
provided in or pursuant to this Indenture with respect to such series.

      Whenever any Securities are surrendered for exchange as contemplated by
the immediately preceding two paragraphs, the Company shall execute, and the
Trustee shall authenticate and deliver, the Securities which the Holder making
the exchange is entitled to receive.

      Notwithstanding the foregoing, except as otherwise provided in or pursuant
to this Indenture, any global Security shall be exchangeable for definitive
Securities only if (i) the Depository is at any time unwilling, unable or
ineligible to continue as depository and a successor depository is not appointed
by the Company within 90 days of the date the Company is so informed in writing,
(ii) the Company executes and delivers to the Trustee a Company Order to the
effect that such global Security shall be so exchangeable, or (iii) an Event of
Default has occurred and is continuing with respect to the Securities. If the
beneficial owners of interests in a global Security are entitled to exchange
such interests for definitive Securities as the result of an event described in
clause (i), (ii) or (iii) of the preceding sentence, then without unnecessary
delay but in any event not later than the earliest date on which such interests
may be so exchanged, the Company shall deliver to the Trustee definitive
Securities in such form and denominations as are required by or pursuant to this
Indenture, and of the same series, containing identical terms and in aggregate
principal amount equal to the principal amount of such global Security, executed
by the Company. On or after the earliest date on which such interests may be so
exchanged, such global Security shall be surrendered from time to time by the
U.S. Depository or such other Depository as shall be specified in the Company
Order with respect thereto, and in accordance with instructions given to the
Trustee and the U.S. Depository or such other Depository, as the case may be
(which instructions shall be in writing but need not be contained in or
accompanied by an Officer's Certificate or be accompanied by an Opinion of
Counsel), as shall be specified in the Company Order with respect thereto to the
Trustee, as the


                                       28
<PAGE>

Company's agent for such purpose, to be exchanged, in whole or in part, for
definitive Securities as described above without charge. The Trustee shall
authenticate and make available for delivery, in exchange for each portion of
such surrendered global Security, a like aggregate principal amount of
definitive Securities of the same series of authorized denominations and of like
tenor as the portion of such global Security to be exchanged, which (unless such
Securities are not issuable both as Bearer Securities and as Registered
Securities, in which case the definitive Securities exchanged for the global
Security shall be issuable only in the form in which the Securities are
issuable, as provided in or pursuant to this Indenture) shall be in the form of
Bearer Securities or Registered Securities, or any combination thereof, as shall
be specified by the beneficial owner thereof, but subject to the satisfaction of
any certification or other requirements to the issuance of Bearer Securities;
provided, however, that no such exchanges may occur during a period beginning at
the opening of business 15 days before any selection of Securities of the same
series to be redeemed and ending on the relevant Redemption Date; and provided,
further, that (unless otherwise provided in or pursuant to this Indenture) no
Bearer Security delivered in exchange for a portion of a global Security shall
be mailed or otherwise delivered to any location in the United States. Promptly
following any such exchange in part, such global Security shall be returned by
the Trustee to such Depository or the U.S. Depository, as the case may be, or
such other Depository or U.S. Depository referred to above in accordance with
the instructions of the Company referred to above. If a Registered Security is
issued in exchange for any portion of a global Security after the close of
business at the Office or Agency for such Security where such exchange occurs on
or after (i) any Regular Record Date for such Security and before the opening of
business at such Office or Agency on the next succeeding Interest Payment Date,
or (ii) any Special Record Date for such Security and before the opening of
business at such Office or Agency on the related proposed date for payment of
interest or Defaulted Interest, as the case may be, interest shall not be
payable on such Interest Payment Date or proposed date for payment, as the case
may be, in respect of such Registered Security, but shall be payable on such
Interest Payment Date or proposed date for payment, as the case may be, only to
the Person to whom interest in respect of such portion of such global Security
shall be payable in accordance with the provisions of this Indenture.

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

      Every Registered Security presented or surrendered for registration of
transfer or for exchange or redemption shall (if so required by the Company or
the Security Registrar for such Security) be duly endorsed, or be accompanied by
a written instrument of transfer in form satisfactory to the Company and the
Security Registrar for such Security 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, or redemption of Securities, but the Company may require payment of a
sum sufficient to cover any tax or other governmental charge and any other
expenses (including fees and expenses of the Trustee) that may be imposed in
connection with any registration of transfer or exchange of Securities, other
than exchanges pursuant to Section 3.4, 9.5 or 11.7 not involving any transfer.


                                       29
<PAGE>

      Except as otherwise provided in or pursuant to this Indenture, the Company
shall not be required (i) to issue, register the transfer of or exchange any
Securities during a period beginning at the opening of business 15 days before
the day of mailing of a notice of redemption of Securities of like tenor and the
same series under Section 11.3 and ending at the close of business on the day of
such mailing, or (ii) to register the transfer of or exchange any Registered
Security selected for redemption in whole or in part, except in the case of any
Security to be redeemed in part, the portion thereof not to be redeemed, or
(iii) to exchange any Bearer Security selected for redemption except, to the
extent provided with respect to such Bearer Security, that such Bearer Security
may be exchanged for a Registered Security of like tenor and the same series,
provided that such Registered Security shall be immediately surrendered for
redemption with written instruction for payment consistent with the provisions
of this Indenture or (iv) to issue, register the transfer of or exchange any
Security which, in accordance with its terms, has been surrendered for repayment
at the option of the Holder, except the portion, if any, of such Security not to
be so repaid.

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

      If any mutilated Security or a Security with a mutilated Coupon
appertaining to it is surrendered to the Trustee, subject to the provisions of
this Section 3.6, the Company shall execute and the Trustee shall authenticate
and deliver in exchange therefor a new Security of the same series containing
identical terms and of like principal amount and bearing a number not
contemporaneously outstanding, with Coupons appertaining thereto corresponding
to the Coupons, if any, appertaining to the surrendered Security.

      If there be delivered to the Company and to the Trustee (i) evidence to
their satisfaction of the destruction, loss or theft of any Security or Coupon,
and (ii) such security 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 Security or Coupon has been acquired by a
bona fide purchaser, the Company shall execute and, upon the Company's request
the Trustee shall authenticate and deliver, in exchange for or in lieu of any
such mutilated, destroyed, lost or stolen Security or in exchange for the
Security to which a destroyed, lost or stolen Coupon appertains with all
appurtenant Coupons not destroyed, lost or stolen, a new Security of the same
series containing identical terms and of like principal amount and bearing a
number not contemporaneously outstanding, with Coupons appertaining thereto
corresponding to the Coupons, if any, appertaining to such destroyed, lost or
stolen Security or to the Security to which such destroyed, lost or stolen
Coupon appertains.

      Notwithstanding the foregoing provisions of this Section 3.6, in case any
mutilated, destroyed, lost or stolen Security or Coupon has become or is about
to become due and payable, the Company in its discretion may, instead of issuing
a new Security, pay such Security or Coupon; provided, however, that payment of
principal of, any premium or interest on or any Additional Amounts with respect
to any Bearer Securities shall, except as otherwise provided in Section 10.2, be
payable only at an Office or Agency for such Securities located outside the
United States and, unless otherwise provided in or pursuant to this Indenture,
any interest on Bearer Securities and any Additional Amounts with respect to
such interest shall be payable only upon presentation and surrender of the
Coupons appertaining thereto.

      Upon the issuance of any new Security under this Section 3.6, the Company
may require the payment of a sum sufficient to cover any tax or other
governmental charge that may be imposed in relation thereto and any other
expenses (including the fees and expenses of the Trustee) connected therewith.

      Every new Security, with any Coupons appertaining thereto issued pursuant
to this Section 3.6 in lieu of any destroyed, lost or stolen Security, or in
exchange for a Security to which a destroyed, lost or stolen Coupon appertains
shall constitute a separate obligation of the Company, whether or not the
destroyed, lost or stolen Security and Coupons appertaining thereto or the
destroyed, lost or stolen Coupon shall be at any time enforceable by anyone, and
shall be entitled to all the benefits of this Indenture equally and
proportionately with any and all other Securities of such series and any
Coupons, if any, duly issued hereunder.

      The provisions of this Section 3.6, as amended or supplemented pursuant to
this Indenture with respect to particular Securities or generally, shall be
exclusive and shall preclude (to the extent lawful) all other rights and
remedies with respect to the replacement or payment of mutilated, destroyed,
lost or stolen Securities or Coupons.

      Section 3.7. Payment of Interest and Certain Additional Amounts; Rights to
                   Interest and Certain Additional Amounts Preserved.

      Unless otherwise provided in or pursuant to this Indenture, any interest
on and any Additional Amounts with respect to any Registered Security which
shall be payable, and are punctually paid or duly provided for, on any Interest
Payment Date shall be paid to the Person in whose name such Security (or one or
more Predecessor Securities) is registered as of the close of business on the
Regular Record Date for such interest.

      Unless otherwise provided in or pursuant to this Indenture, any interest
on and any Additional Amounts with respect to any Registered Security which
shall be payable, but shall not be punctually paid or duly provided for, on any
Interest Payment Date for such Registered Security (herein called "Defaulted
Interest") shall forthwith cease to be payable to the Holder thereof on the
relevant Regular Record Date by virtue of having been such Holder; and such
Defaulted Interest may be paid by the Company, at its election in each case, as
provided in Clause (1) or (2) below:

            (1) The Company may elect to make payment of any Defaulted Interest
      to the Person in whose name such Registered Security (or a Predecessor
      Security thereof) shall be registered at the close of business on a
      Special Record Date for the payment of such Defaulted Interest, which
      shall be fixed by the Company in the following manner. The Company shall
      notify the Trustee in writing of the amount of Defaulted Interest proposed
      to be paid on such Registered Security, the Special Record Date therefor
      and the date of the proposed payment, and at the same time the Company
      shall deposit with the Trustee an amount of money equal to the aggregate
      amount proposed to be paid in respect of such Defaulted Interest or shall
      make arrangements satisfactory to the Trustee for such deposit on or prior
      to the date of the proposed payment, such money when so deposited to be
      held in trust for the benefit of the Person entitled to such Defaulted
      Interest as in this Clause provided. The Special Record Date for the
      payment of such Defaulted Interest shall be


                                       31
<PAGE>

      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 notification to the
      Trustee of the proposed payment. The Trustee shall, in the name and at the
      expense of the Company, cause notice of the proposed payment of such
      Defaulted Interest and the Special Record Date therefor to be mailed,
      first-class postage prepaid, to the Holder of such Registered Security (or
      a Predecessor Security thereof) at his address as it appears in the
      Security Register not less than 10 days prior to such Special Record Date.
      The Trustee may, in its discretion, in the name and at the expense of the
      Company cause a similar notice to be published at least once in an
      Authorized Newspaper of general circulation in the Borough of Manhattan,
      The City of New York, but such publication shall not be a condition
      precedent to the establishment of such Special Record Date. Notice of the
      proposed payment of such Defaulted Interest and the Special Record Date
      therefor having been mailed as aforesaid, such Defaulted Interest shall be
      paid to the Person in whose name such Registered Security (or a
      Predecessor Security thereof) shall be registered at the close of business
      on such Special Record Date and shall no longer be payable pursuant to the
      following clause (2).

            (2) The Company may make payment of any Defaulted Interest in any
      other lawful manner not inconsistent with the requirements of any
      securities exchange on which such Security may be listed, and 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,
      such payment shall be deemed practicable by the Trustee.

      Unless otherwise provided in or pursuant to this Indenture or the
Securities of any particular series pursuant to the provisions of this
Indenture, at the option of the Company, interest on Registered Securities that
bear interest may be paid by mailing a check to the address of the Person
entitled thereto as such address shall appear in the Security Register or by
transfer to an account maintained by the payee with a bank located in the United
States.

      Subject to the foregoing provisions of this Section and Section 3.5, each
Security delivered under this Indenture upon registration of transfer of or in
exchange for or in lieu of any other Security shall carry the rights to interest
accrued and unpaid, and to accrue, which were carried by such other Security.

      In the case of any Registered Security of any series that is convertible
into shares of Common Stock of the Company or exchangeable for other securities,
which Registered Security is converted or exchanged after any Regular Record
Date and on or prior to the next succeeding Interest Payment Date (other than
any Registered Security with respect to which the Stated Maturity is prior to
such Interest Payment Date), interest with respect to which the Stated Maturity
is on such Interest Payment Date shall be payable on such Interest Payment Date
notwithstanding such conversion or exchange, and such interest (whether or not
punctually paid or duly provided for) shall be paid to the Person in whose name
that Registered Security (or one or more predecessor Registered Securities) is
registered at the close of business on such Regular Record Date. Except as
otherwise expressly provided in the immediately preceding sentence, in the case
of any Registered Security which is converted or exchanged, interest with
respect to which the Stated Maturity is after the date of conversion or exchange
of such Registered Security shall not be payable.

      Section 3.8. Persons Deemed Owners.

      Prior to due presentment of a Registered Security 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 Registered Security is registered in the
Security Register as the owner of such Registered Security for the purpose of
receiving payment of principal of, any premium and (subject to Sections 3.5 and
3.7) interest on and any Additional Amounts with respect to such Registered
Security and for all other purposes whatsoever, whether or not any payment with
respect to such Registered Security shall be overdue, and none of the Company,
the Trustee or any agent of the Company or the Trustee shall be affected by
notice to the contrary.

      The Company, the Trustee and any agent of the Company or the Trustee may
treat the bearer of any Bearer Security or the bearer of any Coupon as the
absolute owner of such Security or Coupon for the purpose of receiving payment
thereof or on account thereof and for all other purposes whatsoever, whether or
not any payment with respect to such Security or Coupon shall be overdue, and
none of the Company, the Trustee or any agent of the Company or the Trustee
shall be affected by notice to the contrary

      No Holder of any beneficial interest in any global Security held on its
behalf by a Depository shall have any rights under this Indenture with respect
to such global Security, and such Depository may be treated by the Company, the
Trustee, and any agent of the Company or the Trustee as the owner of such global
Security for all purposes whatsoever. None of the Company, the Trustee, any
Paying Agent or the Security Registrar will have any responsibility or liability
for any aspect of the records relating to or payments made on account of
beneficial ownership interests of a global Security or for maintaining,
supervising or reviewing any records relating to such beneficial ownership
interests.

      Section 3.9. Cancellation.

      All Securities and Coupons surrendered for payment, redemption,
registration of transfer, exchange or conversion or for credit against any
sinking fund payment shall, if surrendered to any Person other than the Trustee,
be delivered to the Trustee, and any such Securities and Coupons, as well as
Securities and Coupons surrendered directly to the Trustee for any such purpose,
shall be cancelled promptly by the Trustee. The Company may at any time deliver
to the Trustee for cancellation any Securities previously authenticated and
delivered hereunder which the Company may have acquired in any manner
whatsoever, and all Securities so delivered shall be cancelled promptly by the
Trustee. No Securities shall be authenticated in lieu of or in exchange for any
Securities cancelled as provided in this Section, except as expressly permitted
by or pursuant to this Indenture. All cancelled Securities and Coupons held by
the Trustee shall be destroyed by the Trustee, unless by a Company Order the
Company directs their return to it.

      Section 3.10. Computation of Interest.

      Except as otherwise provided in or pursuant to this Indenture or in any
Security, interest on the Securities shall be computed on the basis of a 360-day
year of twelve 30-day months.

      delivered and all Coupons appertaining thereto (other than (i) Coupons
      appertaining to Bearer Securities of such series surrendered in exchange

      whose surrender is not required or has been waived as provided in Section

      cancellation; or

            (b) all Securities of such series and, in the case of (i) or (ii)
      below, any Coupons appertaining thereto not theretofore delivered to the
      Trustee for cancellation

                  (i) have become due and payable, or

                  (ii) will become due and payable at their Stated Maturity
            within one year, or

                  (iii) if redeemable at the option of the Company, are to be

      to the Trustee for cancellation, including the principal of, any premium
      and interest on, and any Additional Amounts with respect to such
      Securities and any Coupons appertaining thereto, to the date of such

      to the Maturity thereof, as the case may be;


                                       34
<PAGE>

            (2) the Company has paid or caused to be paid all other sums payable
      hereunder by the Company with respect to the Outstanding Securities of
      such series and any Coupons appertaining thereto; and

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

      In the event there are Securities of two or more series hereunder, the
Trustee shall be required to execute an instrument acknowledging satisfaction
and discharge of this Indenture only if requested to do so with respect to
Securities of such series as to which it is Trustee and if the other conditions
thereto are met.

      Notwithstanding the satisfaction and discharge of this Indenture with
respect to any series of Securities, the obligations of the Company to the
Trustee under Section 6.6 and, if money shall have been deposited with the
Trustee pursuant to subclause (b) of clause (1) of this Section, the obligations

Additional Amounts, if any, with respect to such Securities as contemplated by
Section 10.4 (but only to the extent that the Additional Amounts payable with
respect to such Securities exceed the amount deposited in respect of such
Additional Amounts pursuant to Section 4.1(1)(b)), and with respect to any
rights to convert or exchange such Securities into Common Stock of the Company
or other securities shall survive.

      Section 4.2. Defeasance and Covenant Defeasance.

      (1) Unless pursuant to Section 3.1, either or both of (i) defeasance of
the Securities of or within a series under clause (2) of this Section 4.2 shall
not be applicable with respect to the Securities of such series or (ii) covenant
defeasance of the Securities of or within a series under clause (3) of this
Section 4.2 shall not be applicable with respect to the Securities of such
series, then such provisions, together with the other provisions of this Section
4.2 (with such modifications thereto as may be specified pursuant to Section 3.1
with respect to any Securities), shall be applicable to such Securities and any
Coupons appertaining thereto, and the Company may at its option by Board
Resolution, at any time, with respect to such Securities and any Coupons
appertaining thereto, elect to have Section 4.2(2) or Section 4.2(3) be applied
to such Outstanding Securities and any Coupons appertaining thereto upon
compliance with the conditions set forth below in this Section 4.2.

      (2) Upon the Company's exercise of the above option applicable to this
Section 4.2(2) with respect to any Securities of or within a series, the Company
shall be deemed to have been discharged from its obligations with respect to
such Outstanding Securities and any Coupons appertaining thereto on the date the
conditions set forth in clause (4) of this Section 4.2 are satisfied
(hereinafter, "defeasance"). For this purpose, such defeasance means that the
Company shall be deemed to have paid and discharged the entire Indebtedness
represented by such Outstanding Securities and any Coupons appertaining thereto,
which shall thereafter be deemed to be "Outstanding" only for the purposes of
clause (5) of this Section 4.2 and the other


                                       35
<PAGE>

Sections of this Indenture referred to in clauses (i) and (ii) below, and to
have satisfied all of its other obligations under such Securities and any
Coupons appertaining thereto and this Indenture insofar as such Securities and
any Coupons appertaining thereto are concerned (and the Trustee, at the expense
of the Company, shall execute proper instruments acknowledging the same), except
for the following which shall survive until otherwise terminated or discharged
hereunder: (i) the rights of Holders of such Outstanding Securities and any
Coupons appertaining thereto to receive, solely from the trust fund described in
clause (4) of this Section 4.2 and as more fully set forth in such clause,
payments in respect of the principal of (and premium, if any) and interest, if
any, on, and Additional Amounts, if any, with respect to, such Securities and
any Coupons appertaining thereto when such payments are due, and any rights of
such Holder to convert such Securities into Common Stock of the Company or
exchange such Securities for other securities, (ii) the obligations of the
Company and the Trustee with respect to such Securities under Sections 3.5, 3.6,
10.2 and 10.3 and with respect to the payment of Additional Amounts, if any, on
such Securities as contemplated by Section 10.4 (but only to the extent that the
Additional Amounts payable with respect to such Securities exceed the amount
deposited in respect of such Additional Amounts pursuant to Section 4.2(4)(a)
below), and with respect to any rights to convert such Securities into Common
Stock of the Company or exchange such Securities for other securities, (iii) the
rights, powers, trusts, duties and immunities of the Trustee hereunder and (iv)
this Section 4.2. The Company may exercise its option under this Section 4.2(2)
notwithstanding the prior exercise of its option under clause (3) of this
Section 4.2 with respect to such Securities and any Coupons appertaining
thereto.

      (3) Upon the Company's exercise of the option to have this Section 4.2(3)
apply with respect to any Securities of or within a series, the Company shall be
released from its obligations under any covenant applicable to such Securities
specified pursuant to Section 3.1(20), with respect to such Outstanding
Securities and any Coupons appertaining thereto on and after the date the
conditions set forth in clause (4) of this Section 4.2 are satisfied
(hereinafter, "covenant defeasance"), and such Securities and any Coupons
appertaining thereto shall thereafter be deemed to be not "Outstanding" for the
purposes of any direction, waiver, consent or declaration or Act of Holders (and
the consequences of any thereof) in connection with any such covenant, but shall
continue to be deemed "Outstanding" for all other purposes hereunder. For this
purpose, such covenant defeasance means that, with respect to such Outstanding
Securities and any Coupons appertaining thereto, the Company may omit to comply
with, and shall have no liability in respect of, any term, condition or
limitation set forth in any such Section or such other covenant, whether
directly or indirectly, by reason of any reference elsewhere herein to any such
Section or such other covenant or by reason of reference in any such Section or
such other covenant to any other provision herein or in any other document and
such omission to comply shall not constitute a default or an Event of Default
under Section 5.1(4) or 5.1(9) or otherwise, as the case may be, but, except as
specified above, the remainder of this Indenture and such Securities and Coupons
appertaining thereto shall be unaffected thereby.

      (4) The following shall be the conditions to application of clause (2) or
(3) of this Section 4.2 to any Outstanding Securities of or within a series and
any Coupons appertaining thereto:

      Securities and any Coupons appertaining thereto are then specified as
      payable at Stated Maturity, or (2) Government Obligations applicable to
      such Securities and Coupons appertaining thereto (determined on the basis
      of the Currency in which such Securities and Coupons appertaining thereto
      are then specified as payable at Stated Maturity) which through the
      scheduled payment of principal and interest in respect thereof in
      accordance with their terms will provide, not later than one day before
      the due date of any payment of principal of (and premium, if any) and
      interest, if any, on such Securities and any Coupons appertaining thereto,
      money in an amount, or (3) a combination thereof, in any case, in an
      amount, sufficient, without consideration of any reinvestment of such
      principal and interest, in the opinion of a nationally recognized firm of
      independent public accountants expressed in a written certification
      thereof delivered to the Trustee, to pay and discharge, and which shall be
      applied by the Trustee (or other qualifying trustee) to pay and discharge,

      applicable to such Outstanding Securities and any Coupons appertaining
      thereto on the days on which such payments are due and payable in
      accordance with the terms of this Indenture and of such Securities and any
      Coupons appertaining thereto.

            (b) Such defeasance or covenant defeasance shall not result in a
      breach or violation of, or constitute a default under, this Indenture or
      any other material agreement or instrument to which the Company is a party
      or by which it is bound.

            (c) No Event of Default or event which with notice or lapse of time
      or both would become an Event of Default with respect to such Securities
      and any Coupons appertaining thereto shall have occurred and be continuing
      on the date of such deposit and, with respect to defeasance only, at any
      time during the period ending on the 123rd day after the date of such
      deposit (it being understood that this condition shall not be deemed
      satisfied until the expiration of such period).

            (d) In the case of an election under clause (2) of this Section 4.2,
      the Company shall have delivered to the Trustee an Opinion of Counsel
      stating that (i) the Company has received from the Internal Revenue
      Service a letter ruling, or there has been published by the Internal
      Revenue Service a Revenue Ruling, or (ii) since the date of execution of
      this Indenture, there has been a change in the applicable Federal income
      tax law, in either case to the effect that, and based thereon such opinion
      shall confirm that, the Holders of such Outstanding Securities and any
      Coupons appertaining thereto will not recognize income, gain or loss for
      Federal income tax purposes as a result of such defeasance and will be
      subject to Federal income tax on the same amounts, in the same manner and
      at the same times as would have been the case if such defeasance had not
      occurred.

            (e) In the case of an election under clause (3) of this Section 4.2,
      the Company shall have delivered to the Trustee an Opinion of Counsel to
      the effect that the Holders of such Outstanding Securities and any Coupons
      appertaining thereto will not recognize income, gain or loss for Federal
      income tax purposes as a result of such covenant defeasance and will be
      subject to Federal income tax on the same amounts, in the same manner and
      at the same times as would have been the case if such covenant defeasance
      had not occurred.

            (f) The Company shall have delivered to the Trustee an Opinion of
      Counsel to the effect that, after the 123rd day after the date of deposit,
      all money and Government Obligations (or other property as may be provided
      pursuant to Section 3.1) (including the proceeds thereof) deposited or
      caused to be deposited with the Trustee (or other qualifying trustee)
      pursuant to this clause (4) to be held in trust will not be subject to any
      case or proceeding (whether voluntary or involuntary) in respect of the
      Company under any Federal or State bankruptcy, insolvency, reorganization
      or other similar law, or any decree or order for relief in respect of the
      Company issued in connection therewith.

            (g) The Company shall have delivered to the Trustee an Officer's
      Certificate and an Opinion of Counsel, each stating that all conditions
      precedent to the defeasance or covenant defeasance under clause (2) or (3)
      of this Section 4.2 (as the case may be) have been complied with.

            (h) Notwithstanding any other provisions of this Section 4.2(4),
      such defeasance or covenant defeasance shall be effected in compliance
      with any additional or substitute terms, conditions or limitations which
      may be imposed on the Company in connection therewith pursuant to Section
      3.1.

      (5) Unless otherwise specified in or pursuant to this Indenture or any
Security, if, after a deposit referred to in Section 4.2(4)(a) has been made,
(a) the Holder of a Security in respect of which such deposit was made is
entitled to, and does, elect pursuant to Section 3.1 or the terms of such
Security to receive payment in a Currency other than that in which the deposit
pursuant to Section 4.2(4)(a) has been made in respect of such Security, or (b)
a Conversion Event occurs in respect of the Foreign Currency in which the
deposit pursuant to Section 4.2(4)(a) has been made, the indebtedness
represented by such Security and any Coupons appertaining thereto shall be
deemed to have been, and will be, fully discharged and satisfied through the
payment of the principal of (and premium, if any), and interest, if any, on, and
Additional Amounts, if any, with respect to, such Security as the same becomes
due out of the proceeds yielded by converting (from time to time as specified
below in the case of any such election) the amount or other property deposited
in respect of such Security into the Currency in which such Security becomes
payable as a result of such election or Conversion Event based on (x) in the
case of payments made pursuant to clause (a) above, the applicable market
exchange rate for such Currency in effect on the second Business Day prior to
each payment date, or (y) with respect to a Conversion Event, the applicable
market exchange rate for such Foreign Currency in effect (as nearly as feasible)
at the time of the Conversion Event.

      The Company shall pay and indemnify the Trustee (or other qualifying
trustee, collectively for purposes of this Section 4.2(5) and Section 4.3, the
"Trustee") against any tax,


                                       38

fee or other charge, imposed on or assessed against the Government Obligations
deposited pursuant to this Section 4.2 or the principal or interest received in
respect thereof other than any such tax, fee or other charge which by law is for
the account of the Holders of such Outstanding Securities and any Coupons
appertaining thereto.

      Anything in this Section 4.2 to the contrary notwithstanding, the Trustee
shall deliver or pay to the Company from time to time upon Company Request any
money or Government Obligations (or other property and any proceeds therefrom)
held by it as provided in clause (4) of this Section 4.2 which, in the opinion
of a nationally recognized firm of independent public accountants expressed in a
written certification thereof delivered to the Trustee, are in excess of the
amount thereof which would then be required to be deposited to effect a
defeasance or covenant defeasance, as applicable, in accordance with this
Section 4.2.

      Section 4.3. Application of Trust Money.

      Subject to the provisions of the last paragraph of Section 10.3, all money
and Government Obligations (or other property as may be provided pursuant to
Section 3.1) (including the proceeds thereof) deposited with the Trustee
pursuant to Section 4.1 or 4.2 in respect of any Outstanding Securities of any
series and any Coupons appertaining thereto shall be held in trust and applied
by the Trustee, in accordance with the provisions of such Securities and any
Coupons appertaining thereto and this Indenture, to the payment, either directly
or through any Paying Agent (including the Company acting as its own Paying
Agent) as the Trustee may determine, to the Holders of such Securities and any
Coupons appertaining thereto of all sums due and to become due thereon in
respect of principal (and premium, if any) and interest and Additional Amounts,
if any; but such money and Government Obligations need not be segregated from
other funds except to the extent required by law.

      (9) any other Event of Default provided in or pursuant to this Indenture

      Section 5.2. Acceleration of Maturity; Rescission and Annulment.

      If an Event of Default with respect to Securities of any series at the
time Outstanding (other than an Event of Default specified in clause (7) or (8)
of Section 5.1) occurs and is continuing, then the Trustee or the Holders of not
less than 25% in principal amount of the Outstanding Securities of such series
may declare the principal of all the Securities of such series, or such lesser
amount as may be provided for in the Securities of such series, to be due and
payable immediately, by a notice in writing to the Company (and to the Trustee
if given by the Holders), and upon any such declaration such principal or such
lesser amount shall become immediately due and payable.

      If an Event of Default specified in clause (7) or (8) of Section 5.1
occurs, all unpaid principal of and accrued interest on the Outstanding
Securities of that series (or such lesser amount as may be provided for in the
Securities of such series) shall ipso facto become and be immediately due and
payable without any declaration or other act on the part of the Trustee or any
Holder of any Security of that series.

      At any time after a declaration of acceleration with respect to the
Securities of any series has been made and before a judgment or decree for
payment of the money due has been obtained by the Trustee as hereinafter in this
Article provided, the Holders of not less than a majority in


                                       41
<PAGE>

principal amount of the Outstanding Securities of such series, by written notice
to the Company and the Trustee, may rescind and annul such declaration and its
consequences if

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

            (a) all overdue installments of any interest on and Additional
      Amounts with respect to all Securities of such series and any Coupon
      appertaining thereto,

            (b) the principal of and any premium on any Securities of such
      series which have become due otherwise than by such declaration of
      acceleration and interest thereon and any Additional Amounts with respect
      thereto at the rate or rates borne by or provided for in such Securities,

            (c) to the extent that payment of such interest or Additional
      Amounts is lawful, interest upon overdue installments of any interest and
      Additional Amounts at the rate or rates borne by or provided for in such
      Securities, and

            (d) all sums paid or advanced by the Trustee hereunder and the
      reasonable compensation, expenses, disbursements and advances of the
      Trustee, its agents and counsel and all other amounts due the Trustee
      under Section 6.6; and

      (2) all Events of Default with respect to Securities of such series, other
than the non-payment of the principal of, any premium and interest on, and any
Additional Amounts with respect to Securities of such series which shall have
become due solely by such declaration of acceleration, shall have been cured or
waived as provided in Section 5.13.

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

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

      The Company covenants that if

      (1) default is made in the payment of any installment of interest on or
any Additional Amounts with respect to any Security or any Coupon appertaining
thereto when such interest or Additional Amounts shall have become due and
payable and such default continues for a period of 30 days, or

      (2) default is made in the payment of the principal of or any premium on
any Security or any Additional Amounts with respect thereto at their Maturity,

the Company shall, upon demand of the Trustee, pay to the Trustee, for the
benefit of the Holders of such Securities and any Coupons appertaining thereto,
the whole amount of money then due and payable with respect to such Securities
and any Coupons appertaining thereto, with interest upon the overdue principal,
any premium and, to the extent that payment of such interest shall be legally
enforceable, upon any overdue installments of interest and Additional Amounts at
the rate or rates borne by or provided for in such Securities, and, in addition
thereto, such


                                       42
<PAGE>

further amount of money 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 and all other amounts due to
the Trustee under Section 6.6.

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

      If an Event of Default with respect to Securities of any series occurs and
is continuing, the Trustee may in its discretion proceed to protect and enforce
its rights and the rights of the Holders of Securities of such series and any
Coupons appertaining thereto 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 such Securities or in aid of the exercise of any power granted
herein or therein, or to enforce any other proper remedy.

      Section 5.4. Trustee May File Proofs of Claim.

      In case of the pendency of any receivership, insolvency, liquidation,
bankruptcy, reorganization, arrangement, adjustment, composition or other
judicial proceeding relative to the Company or any other obligor upon the
Securities of any series or the property of the Company or such other obligor or
their creditors, the Trustee (irrespective of whether the principal of the
Securities shall then be due and payable as therein expressed or by declaration
or otherwise and irrespective of whether the Trustee shall have made any demand
on the Company for the payment of any overdue principal, premium, interest or
Additional Amounts) shall be entitled and empowered, by intervention in such
proceeding or otherwise,

            (1) to file and prove a claim for the whole amount, or such lesser
      amount as may be provided for in the Securities of any applicable series,
      of the principal and any premium, interest and Additional Amounts owing
      and unpaid in respect of the Securities and any Coupons appertaining
      thereto and to file such other papers or documents as may be necessary or
      advisable in order to have the claims of the Trustee (including any claim
      for the reasonable compensation, expenses, disbursements and advances of
      the Trustee, its agents or counsel) and of the Holders of Securities or
      any Coupons appertaining thereto allowed in such judicial proceeding, and

            (2) to collect and receive any monies 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 of Securities or any Coupons to make such payments to the Trustee
and, in the event that the Trustee shall consent to the


                                       43
<PAGE>

making of such payments directly to the Holders of Securities or any Coupons, to
pay to the Trustee any amount due to 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 6.6.

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

      Section 5.5. Trustee May Enforce Claims without Possession of Securities
                   or Coupons.

      All rights of action and claims under this Indenture or any of the
Securities or Coupons may be prosecuted and enforced by the Trustee without the
possession of any of the Securities or Coupons or the production thereof in any
proceeding relating thereto, and any such proceeding instituted by the Trustee
shall be brought in its own name as trustee of an express trust, and any
recovery or judgment, after provision for the payment of the reasonable
compensation, expenses, disbursements and advances of the Trustee, its agents
and counsel, shall be for the ratable benefit of each and every Holder of the
Securities or Coupons in respect of which such judgment has been recovered.

      Section 5.6. Application of Money Collected.

      Any money collected by the Trustee pursuant to this Article shall be
applied in the following order, at the date or dates fixed by the Trustee and,
in case of the distribution of such money on account of principal, or any
premium, interest or Additional Amounts, upon presentation of the Securities or
Coupons, or both, as the case may be, and the notation thereon of the payment if
only partially paid and upon surrender thereof if fully paid:

      predecessor Trustee under Section 6.6;

      Securities and any Coupons for principal and any premium, interest and
      Additional Amounts in respect of which or for the benefit of which such
      money has been collected, ratably, without preference or priority of any
      kind, according to the aggregate amounts due and payable on such
      Securities and Coupons for principal and any premium, interest and
      Additional Amounts, respectively;

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

      Section 5.7. Limitations on Suits.

      No Holder of any Security of any series or any Coupons appertaining
thereto shall have any right to institute any proceeding, judicial or otherwise,
with respect to this Indenture, or for the appointment of a receiver or trustee,
or for any other remedy hereunder, unless


                                       44
<PAGE>

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

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

            (3) such Holder or Holders have offered to the Trustee such
      indemnity as is reasonably satisfactory to it against the costs, expenses
      and liabilities to be incurred in compliance with such request;

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

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

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

      Section 5.8. Unconditional Right of Holders to Receive Principal and any
                   Premium, Interest and Additional Amounts.

      Notwithstanding any other provision in this Indenture, the Holder of any
Security or Coupon shall have the right, which is absolute and unconditional, to
receive payment of the principal of, any premium and (subject to Sections 3.5
and 3.7) interest on, and any Additional Amounts with respect to such Security
or payment of such Coupon, as the case may be, on the respective Stated Maturity
or Maturities therefor specified in such Security or Coupon (or, in the case of
redemption, on the Redemption Date or, in the case of repayment at the option of
such Holder if provided in or pursuant to this Indenture, on the date such
repayment is due) and to institute suit for the enforcement of any such payment,
and such right shall not be impaired without the consent of such Holder.

      Section 5.9. Restoration of Rights and Remedies.

      If the Trustee or any Holder of a Security or a Coupon 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 the Company, the Trustee and each such Holder shall, subject to any
determination in such proceeding, be restored severally and respectively to
their former positions hereunder, and thereafter all rights and remedies of the
Trustee and each such Holder shall continue as though no such proceeding had
been instituted.

      Except as otherwise provided with respect to the replacement or payment of
mutilated, destroyed, lost or stolen Securities or Coupons in the last paragraph
of Section 3.6, no right or remedy herein conferred upon or reserved to the
Trustee or to each and every Holder of a Security or a Coupon is intended to be
exclusive of any other right or remedy, and every right and remedy, to the
extent permitted by law, shall 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, to the extent permitted by law, prevent the
concurrent assertion or employment of any other appropriate right or remedy.

      Section 5.11. Delay or Omission Not Waiver.

      No delay or omission of the Trustee or of any Holder of any Security or
Coupon to exercise any right or remedy accruing upon any Event of Default shall
impair any such right or remedy or constitute a waiver of any such Event of
Default or an acquiescence therein. Every right and remedy given by this Article
or by law to the Trustee or to any Holder of a Security or a Coupon may be
exercised from time to time, and as often as may be deemed expedient, by the
Trustee or by such Holder, as the case may be.

      Section 5.12. Control by Holders of Securities.

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

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

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

            (3) such direction is not unduly prejudicial to the rights of the
      other Holders of Securities of such series not joining in such action.

      Section 5.13. Waiver of Past Defaults.

      The Holders of not less than a majority in principal amount of the
Outstanding Securities of any series on behalf of the Holders of all the
Securities of such series and any Coupons appertaining thereto may waive any
past default hereunder with respect to such series and its consequences, except
a default

            (1) in the payment of the principal of, any premium or interest on,
      or any Additional Amounts with respect to, any Security of such series or
      any Coupons appertaining thereto, or


                                       46
<PAGE>

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

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

      Section 5.14. Waiver of Usury, Stay or Extension Laws.

      The Company covenants that (to the extent that it may lawfully do so) it
will not at any time insist upon, or plead, or in any manner whatsoever claim or
take the benefit or advantage of, any usury, stay or extension law wherever
enacted, now or at any time hereafter in force, which may affect the covenants
or the performance of this Indenture; and the Company expressly waives (to the
extent that it may lawfully do so) 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 5.15. Undertaking for Costs

      All parties to this Indenture agree, and each Holder of any Security by
his acceptance thereof shall be deemed to have agreed, that any court may in its
discretion require, in any suit for the enforcement of any right or remedy under
this Indenture, or in any suit against the Trustee for any action taken or
omitted by it as Trustee, the filing by any party litigant in such suit of any
undertaking to pay the costs of such suit, and that such court may in its
discretion assess reasonable costs, including reasonable attorneys' fees,
against any party litigant in such suit having due regard to the merits and good
faith of the claims or defenses made by such party litigant; but the provisions
of this Section 5.15 shall not apply to any suit instituted by the Trustee, to
any suit instituted by any Holder, or group of Holders, holding in the aggregate
more than 10% in principal amount of Outstanding Securities of any series, or to
any suit instituted by any Holder for the enforcement of the payment of the
principal of (or premium, if any) or interest, if any, on or Additional Amounts,
if any, with respect to any Security on or after the respective Stated
Maturities expressed in such Security (or, in the case of redemption, on or
after the Redemption Date, and, in the case of repayment, on or after the date
for repayment) or for the enforcement of the right, if any, to convert or
exchange any Security into Common Stock or other securities in accordance with
its terms.

capacity, may become the owner or pledgee of Securities or Coupons and, subject
to Sections 310(b) and 311 of the Trust Indenture Act, may otherwise deal with
the Company with the same rights it would have if it were not the Trustee,
Authenticating Agent, Paying Agent, Security Registrar or such other Person.

      Section 6.5. Money Held in Trust.

      Except as provided in Section 4.3 and Section 10.3, money held by the
Trustee in trust hereunder need not be segregated from other funds except to the

      Section 6.6. Compensation and Reimbursement.

      The Company agrees:

            (1) to pay to the Trustee from time to time reasonable compensation
      for all services rendered by the Trustee hereunder (which compensation
      shall not be limited by any provision of law in regard to the compensation
      of a trustee of an express trust);

            (2) except as otherwise expressly provided herein, to reimburse the
      Trustee upon its request for all reasonable expenses, disbursements and
      advances incurred or made by the Trustee in accordance with any provision
      of this Indenture or arising out of or in connection with the acceptance
      or administration of the trust or trusts hereunder (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 the Trustee's negligence or bad faith; and

      employees for, and to hold them harmless against, any loss, liability or
      expense incurred without negligence or bad faith on their part, arising
      out of or in connection with the acceptance or administration of the trust
      or trusts hereunder, including the costs and expenses of defending
      themselves against any claim or liability in connection with the exercise
      or performance of any of their powers or duties hereunder, except to the
      extent that any such loss, liability or expense was due to the Trustee's
      negligence or bad faith.

      As security for the performance of the obligations of the Company under
this Section, the Trustee shall have a lien prior to the Securities of any
series upon all property and funds held or collected by the Trustee as such,
except funds held in trust for the payment of principal of, and premium or
interest on or any Additional Amounts with respect to Securities or any Coupons
appertaining thereto.

      To the extent permitted by law, any compensation or expense incurred by
the Trustee after a default specified in or pursuant to Section 5.1 is intended
to constitute an expense of administration under any then applicable bankruptcy
or insolvency law. "Trustee" for purposes of this Section 6.6 shall include any
predecessor Trustee but the negligence or bad faith of any Trustee shall not
affect the rights of any other Trustee under this Section 6.6.


                                       50
<PAGE>

      The provisions of this Section 6.6 shall survive the satisfaction and

acceptance of appointment by the successor Trustee pursuant to Section 6.9.

      (2) The Trustee may resign at any time with respect to the Securities of
one or more series by giving written notice thereof to the Company. If the
instrument of acceptance by a successor Trustee required by Section 6.9 shall
not have been delivered to the Trustee within 30 days after the giving of such
notice of resignation, the resigning Trustee may petition any court of competent
jurisdiction for the appointment of a successor Trustee with respect to such
series.

      (3) The Trustee may be removed at any time with respect to the Securities
of any series by Act of the Holders of a majority in principal amount of the
Outstanding Securities of such series, delivered to the Trustee and the Company.

      (4) If at any time:

            (a) the Trustee shall fail to comply with the obligations imposed
      upon it under Section 310(b) of the Trust Indenture Act with respect to
      Securities of any series after written request therefor by the Company or
      any Holder of a Security of such series who has been a bona fide Holder of

      such Holder, or

            (c) the Trustee shall become incapable of acting or shall be
      adjudged a bankrupt or insolvent or a receiver of the Trustee or of its
      property shall be appointed or any public officer shall take charge or
      control of the Trustee or of its property or affairs for the purpose of

may remove the Trustee with respect to all Securities or the Securities of such
series, or (ii) subject to Section 315(e) of the Trust Indenture Act, any Holder
of a Security who has been a bona fide Holder of a Security of such series for
at least six months may, on behalf of himself and all others similarly situated,
petition any court of competent jurisdiction for the removal of the Trustee with

Trustee or Trustees.

      (5) If the Trustee shall resign, be removed or become incapable of acting,
or if a vacancy shall occur in the office of Trustee for any cause, with respect
to the Securities of one or more series, the Company, by or pursuant to a Board
Resolution, shall promptly appoint a successor Trustee or Trustees with respect
to the Securities of such series (it being understood that any such successor
Trustee may be appointed with respect to the Securities of one or more or all of
such series and that at any time there shall be only one Trustee with respect to
the Securities of any particular series) and shall comply with the applicable
requirements of Section 6.9. If, within one year after such resignation, removal
or incapacity, or the occurrence of such vacancy, a successor Trustee with
respect to the Securities of any series shall be appointed by Act of the Holders
of a majority in principal amount of the Outstanding Securities of such series
delivered to the Company and the retiring Trustee, the successor Trustee so
appointed shall, forthwith upon its acceptance of such appointment in accordance
with the applicable requirements of Section 6.9, become the successor Trustee
with respect to the Securities of such series and to that extent supersede the
successor Trustee appointed by the Company. If no successor Trustee with respect
to the Securities of any series shall have been so appointed by the Company or
the Holders of Securities and accepted appointment in the manner required by
Section 6.9, any Holder of a Security who has been a bona fide Holder of a
Security of such series for at least six months may, on behalf of himself and
all others similarly situated, petition any court of competent jurisdiction for
the appointment of a successor Trustee with respect to the Securities of such
series.

the Trustee with respect to the Securities of any series and each appointment of
a successor Trustee with respect to the Securities of any series by mailing
written notice of such event by first-class mail, postage prepaid, to the
Holders of Registered Securities, if any, of such series as their names and
addresses appear in the Security Register and, if Securities of such series are
issued as Bearer Securities, by publishing notice of such event once in an
Authorized Newspaper in each Place of Payment located outside the United States.
Each notice shall include the name of the successor Trustee with respect to the
Securities of such series and the address of its Corporate Trust Office.

      (7) In no event shall any retiring Trustee be liable for the acts or
omissions of any successor Trustee hereunder.

      Section 6.9. Acceptance of Appointment by Successor.

      (1) Upon the appointment hereunder of any successor Trustee with respect
to all Securities, such successor Trustee so appointed shall execute,
acknowledge and deliver to the Company and the retiring Trustee an instrument
accepting such appointment, and thereupon the resignation or removal of the
retiring Trustee shall become effective and such successor Trustee,


                                       52
<PAGE>

without any further act, deed or conveyance, shall become vested with all the
rights, powers, trusts and duties hereunder of the retiring Trustee; but, on the
request of the Company or such successor Trustee, such retiring Trustee, upon
payment of its charges, shall execute and deliver an instrument transferring to
such successor Trustee all the rights, powers and trusts of the retiring Trustee
and, subject to Section 10.3, shall duly assign, transfer and deliver to such
successor Trustee all property and money held by such retiring Trustee
hereunder, subject nevertheless to its claim, if any, provided for in Section
6.6.

      (2) Upon the appointment hereunder of any successor Trustee with respect
to the Securities of one or more (but not all) series, the Company, the retiring
Trustee and such successor Trustee shall execute and deliver an indenture
supplemental hereto wherein each successor Trustee shall accept such appointment
and which (1) shall contain such provisions as shall be necessary or desirable
to transfer and confirm to, and to vest in, such successor Trustee all the
rights, powers, trusts and duties of the retiring Trustee with respect to the
Securities of that or those series to which the appointment of such successor
Trustee relates, (2) if the retiring Trustee is not retiring with respect to all
Securities, shall contain such provisions as shall be deemed necessary or
desirable to confirm that all the rights, powers, trusts and duties of the
retiring Trustee with respect to the Securities of that or those series as to
which the retiring Trustee is not retiring shall continue to be vested in the
retiring Trustee, and (3) shall add to or change any of the provisions of this
Indenture as shall be necessary to provide for or facilitate the administration
of the trusts hereunder by more than one Trustee, it being understood that
nothing herein or in such supplemental indenture shall constitute such Trustees
co-trustees of the same trust, that each such Trustee shall be trustee of a
trust or trusts hereunder separate and apart from any trust or trusts hereunder
administered by any other such Trustee and that no Trustee shall be responsible
for any notice given to, or received by, or any act or failure to act on the
part of any other Trustee hereunder, and, upon the execution and delivery of
such supplemental indenture, the resignation or removal of the retiring Trustee
shall become effective to the extent provided therein, such retiring Trustee
shall have no further responsibility for the exercise of rights and powers or
for the performance of the duties and obligations vested in the Trustee under
this Indenture with respect to the Securities of that or those series to which
the appointment of such successor Trustee relates other than as hereinafter
expressly set forth, and such successor Trustee, without any further act, deed
or conveyance, shall become vested with all the rights, powers, trusts and
duties of the retiring Trustee with respect to the Securities of that or those
series to which the appointment of such successor Trustee relates; but, on
request of the Company or such successor Trustee, such retiring Trustee, upon
payment of its charges with respect to the Securities of that or those series to
which the appointment of such successor Trustee relates and subject to Section
10.3 shall duly assign, transfer and deliver to such successor Trustee, to the
extent contemplated by such supplemental indenture, the property and money held
by such retiring Trustee hereunder with respect to the Securities of that or
those series to which the appointment of such successor Trustee relates, subject
to its claim, if any, provided for in Section 6.6.

      (3) Upon request of any Person appointed hereunder as a successor Trustee,
the Company shall execute any and all instruments for more fully and certainly
vesting in and confirming to such successor Trustee all such rights, powers and
trusts referred to in paragraph (1) or (2) of this Section, as the case may be.


                                       53

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

      Section 6.10. Merger, Conversion, Consolidation or Succession to Business.

      Any Corporation into which the Trustee may be merged or converted or with
which it may be consolidated, or any Corporation resulting from any merger,
conversion or consolidation to which the Trustee shall be a party, shall be the
successor of the Trustee hereunder, without the execution or filing of any paper
or any further act on the part of any of the parties hereto. In case any
Securities shall have been authenticated but not delivered by the Trustee then
in office, any successor by merger, conversion or consolidation to such
authenticating Trustee may adopt such authentication and deliver the Securities
so authenticated with the same effect as if such successor Trustee had itself
authenticated such Securities.

      Section 6.11. Appointment of Authenticating Agent.

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

      Each Authenticating Agent must be acceptable to the Company and, except as
provided in or pursuant to this Indenture, shall at all times be a corporation
that would be permitted by the Trust Indenture Act to act as trustee under an
indenture qualified under the Trust Indenture Act, is authorized under
applicable law and by its charter to act as an Authenticating Agent and has a
combined capital and surplus (computed in accordance with Section 310(a)(2) of
the Trust Indenture Act) of at least $50,000,000. If at any time an
Authenticating Agent shall cease to be eligible in accordance with the
provisions of this Section, it shall resign immediately in the manner and with
the effect specified in this Section.

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

      An Authenticating Agent may resign at any time by giving written notice
thereof to the Trustee and the Company. The Trustee may at any time terminate
the agency of an


                                       54
<PAGE>

Authenticating Agent by giving written notice thereof to such Authenticating
Agent and the Company. Upon receiving such a notice of resignation or upon such
a termination, or in case at any time such Authenticating Agent shall cease to
be eligible in accordance with the provisions of this Section, the Trustee may
appoint a successor Authenticating Agent which shall be acceptable to the
Company and shall (i) mail written notice of such appointment by first-class
mail, postage prepaid, to all Holders of Registered Securities, if any, of the
series with respect to which such Authenticating Agent shall serve, as their
names and addresses appear in the Security Register, and (ii) if Securities of
the series are issued as Bearer Securities, publish notice of such appointment
at least once in an Authorized Newspaper in the place where such successor
Authenticating Agent has its principal office if such office is located outside
the United States. Any successor Authenticating Agent, upon acceptance of its
appointment hereunder, shall become vested with all the rights, powers and
duties of its predecessor hereunder, with like effect as if originally named as
an Authenticating Agent. No successor Authenticating Agent shall be appointed
unless eligible under the provisions of this Section.

      The Company agrees to pay each Authenticating Agent from time to time
reasonable compensation for its services under this Section. If the Trustee
makes such payments, it shall be entitled to be reimbursed for such payments,
subject to the provisions of Section 6.6.

      The provisions of Sections 3.8, 6.3 and 6.4 shall be applicable to each
Authenticating Agent.

      If an Authenticating Agent is appointed with respect to one or more series
of Securities pursuant to this Section, the Securities of such series may have
endorsed thereon, in addition to or in lieu of the Trustee's certificate of
authentication, an alternate certificate of authentication in substantially the
following form:

            This is one of the Securities of the series designated herein
      referred to in the within-mentioned Indenture.

                                    THE FIRST NATIONAL BANK OF CHICAGO,
                                          as Trustee


                                    By _________________________________________
                                       as Authenticating Agent


                                    By _________________________________________
                                       Authorized Officer

      If all of the Securities of any series may not be originally issued at one
time, and if the Trustee does not have an office capable of authenticating
Securities upon original issuance located in a Place of Payment where the
Company wishes to have Securities of such series authenticated upon original
issuance, the Trustee, if so requested in writing (which writing need not be
accompanied by or contained in an Officer's Certificate by the Company), shall
appoint in accordance with this Section an Authenticating Agent having an office
in a Place of Payment designated by the Company with respect to such series of
Securities.

      Section 9.6. Conformity with Trust Indenture Act.

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

      Section 9.7. Effect on Senior Indebtedness.

      No supplemental indenture shall directly or indirectly modify or eliminate

Senior Indebtedness.

      Section 9.8. Notice of Supplemental Indenture.

      Promptly after the execution by the Company and the Trustee of any

                                   ARTICLE 10

                                    COVENANTS

      Section 10.1. Payment of Principal, any Premium, Interest and Additional
Amounts.

      The Company covenants and agrees for the benefit of the Holders of the
Securities of each series that it will duly and punctually pay the principal of,
any premium and interest on and any Additional Amounts with respect to the
Securities of such series in accordance with the terms thereof, any Coupons
appertaining thereto and this Indenture. Any interest due on any Bearer Security
on or before the Maturity thereof, and any Additional Amounts payable with
respect to such interest, shall be payable only upon presentation and surrender
of the Coupons appertaining thereto for such interest as they severally mature.

      Section 10.2. Maintenance of Office or Agency.

      The Company shall maintain in each Place of Payment for any series of
Securities an Office or Agency where Securities of such series (but not Bearer
Securities, except as otherwise provided below, unless such Place of Payment is
located outside the United States) may be presented or surrendered for payment,
where Securities of such series may be surrendered for registration of transfer
or exchange, where Securities of such series that are convertible or
exchangeable may be surrendered for conversion or exchange, and where notices
and demands to or upon the Company in respect of the Securities of such series
relating thereto and this Indenture may be served. If Securities of a series are
issuable as Bearer Securities, the Company shall maintain, subject to any laws
or regulations applicable thereto, an Office or Agency in a Place of Payment for
such series which is located outside the United States where Securities of


                                       62
<PAGE>

such series and any Coupons appertaining thereto may be presented and
surrendered for payment; provided, however, that if the Securities of such
series are listed on The Stock Exchange of the United Kingdom and the Republic
of Ireland or the Luxembourg Stock Exchange or any other stock exchange located
outside the United States and such stock exchange shall so require, the Company
shall maintain a Paying Agent in London, Luxembourg or any other required city
located outside the United States, as the case may be, so long as the Securities
of such series are listed on such exchange. 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, except that Bearer
Securities of such series and any Coupons appertaining thereto may be presented
and surrendered for payment at the place specified for the purpose with respect
to such Securities as provided in or pursuant to this Indenture, and the Company
hereby appoints the Trustee as its agent to receive all such presentations,
surrenders, notices and demands.

      Except as otherwise provided in or pursuant to this Indenture, no payment
of principal, premium, interest or Additional Amounts with respect to Bearer
Securities shall be made at any Office or Agency in the United States or by
check mailed to any address in the United States or by transfer to an account
maintained with a bank located in the United States; provided, however, if
amounts owing with respect to any Bearer Securities shall be payable in Dollars,
payment of principal of, any premium or interest on and any Additional Amounts
with respect to any such Security may be made at the Corporate Trust Office of
the Trustee or any Office or Agency designated by the Company in the Borough of
Manhattan, The City of New York, if (but only if) payment of the full amount of
such principal, premium, interest or Additional Amounts at all offices outside
the United States maintained for such purpose by the Company in accordance with
this Indenture is illegal or effectively precluded by exchange controls or other
similar restrictions.

      The Company may also from time to time designate one or more other Offices
or Agencies where the Securities of one or more series 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 each Place of Payment for Securities of any series for such purposes. The
Company shall 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. Unless otherwise provided in or pursuant to this Indenture, the Company
hereby designates as the Place of Payment for each series of Securities the
Borough of Manhattan, The City of New York, and initially appoints the Corporate
Trust Office of the Trustee as the Office or Agency of the Company in the
Borough of Manhattan, The City of New York for such purpose. The Company may
subsequently appoint a different Office or Agency in the Borough of Manhattan,
The City of New York for the Securities of any series.

      Unless otherwise specified with respect to any Securities pursuant to
Section 3.1, if and so long as the Securities of any series (i) are denominated
in a Foreign Currency or (ii) may be payable in a Foreign Currency, or so long
as it is required under any other provision of this


                                       63
<PAGE>

Indenture, then the Company will maintain with respect to each such series of
Securities, or as so required, at least one exchange rate agent.

      Section 10.3. Money for Securities Payments to Be Held in Trust.

      If the Company shall at any time act as its own Paying Agent with respect
to any series of Securities, it shall, on or before each due date of the
principal of, any premium or interest on or Additional Amounts with respect to
any of the Securities of such series, segregate and hold in trust for the
benefit of the Persons entitled thereto a sum in the currency or currencies,
currency unit or units or composite currency or currencies in which the
Securities of such series are payable (except as otherwise specified pursuant to
Section 3.1 for the Securities of such series) sufficient to pay the principal
or any premium, interest or Additional Amounts so becoming due until such sums
shall be paid to such Persons or otherwise disposed of as herein provided, and
shall promptly notify the Trustee of its action or failure so to act.

      Whenever the Company shall have one or more Paying Agents for any series
of Securities, it shall, on or prior to each due date of the principal of, any
premium or interest on or any Additional Amounts with respect to any Securities
of such series, deposit with any Paying Agent a sum (in the currency or
currencies, currency unit or units or composite currency or currencies described
in the preceding paragraph) sufficient to pay the principal or any premium,
interest or Additional Amounts so becoming due, such sum to be held in trust for
the benefit of the Persons entitled thereto, 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 shall cause each Paying Agent for any series of Securities
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 shall:

      (1) hold all sums held by it for the payment of the principal of, any
premium or interest on or any Additional Amounts with respect to Securities of
such series in trust for the benefit of the Persons entitled thereto until such
sums shall be paid to such Persons or otherwise disposed of as provided in or
pursuant to this Indenture;

      (2) give the Trustee notice of any default by the Company (or any other
obligor upon the Securities of such series) in the making of any payment of
principal, any premium or interest on or any Additional Amounts with respect to
the Securities of such series; and

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

      The Company may at any time, for the purpose of obtaining the satisfaction
and discharge of this Indenture or for any other purpose, pay, or by Company
Order direct any Paying Agent to pay, to the Trustee all sums held in trust by
the Company or such Paying Agent, such sums to be held by the Trustee upon the
same terms 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 sums.


                                       64
<PAGE>

      Except as otherwise provided herein or pursuant hereto, 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, any premium or interest on or any
Additional Amounts with respect to any Security of any series or any Coupon
appertaining thereto and remaining unclaimed for two years after such principal
or any such premium or interest or any such Additional Amounts shall have 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 such
Security or any Coupon appertaining thereto shall thereafter, as an unsecured
general creditor, look only to the Company for payment thereof, and all
liability of the Trustee or such Paying Agent with respect to such trust money,
and all liability of the Company as trustee thereof, shall thereupon cease;
provided, however, that the Trustee or such Paying Agent, before being required
to make any such repayment, may at the expense of the Company cause to be
published once, in an Authorized Newspaper in each Place of Payment for such
series or to be mailed to Holders of Registered Securities of such series, or
both, notice that such money remains unclaimed and that, after a date specified
therein, which shall not be less than 30 days from the date of such publication
or mailing nor shall it be later than two years after such principal and any
premium or interest or Additional Amounts shall have become due and payable, any
unclaimed balance of such money then remaining will be repaid to the Company.

      Section 10.4. Additional Amounts.

      All payments of principal of and premium, if any, interest and any other
amounts on, or in respect of, the Securities of any series or any Coupon
appertaining thereto shall be made without withholding or deduction at source
for, or on account of, any present or future taxes, fees, duties, assessments or
governmental charges of whatever nature imposed or levied by or on behalf of the
Cayman Islands or Bermuda (each, a "taxing jurisdiction") or any political
subdivision or taxing authority thereof or therein, unless such taxes, fees,
duties, assessments or governmental charges are required to be withheld or
deducted by (i) the laws (or any regulations or ruling promulgated thereunder)
of a taxing jurisdiction or any political subdivision or taxing authority
thereof or therein or (ii) an official position regarding the application,
administration, interpretation or enforcement of any such laws, regulations or
rulings (including, without limitation, a holding by a court of competent
jurisdiction or by a taxing authority in a taxing jurisdiction or any political
subdivision thereof). If a withholding or deduction at source is required, the
Company shall, subject to certain limitations and exceptions set forth below,
pay to the Holder of any such Security or any Coupon appertaining thereto such
Additional Amounts as may be necessary so that every net payment of principal,
premium, if any, interest or any other amount made to such Holder, after such
withholding or deduction, shall not be less than the amount provided for in such
Security, any Coupons appertaining thereto and this Indenture to be then due and
payable; provided, however, that the Company shall not be required to make
payment of such Additional Amounts for or on account of:

            (1) any tax, fee, duty, assessment or governmental charge of
      whatever nature which would not have been imposed but for the fact that
      such Holder: (A) was a resident, domiciliary or national of, or engaged in
      business or maintained a permanent establishment or was physically present
      in, the relevant taxing jurisdiction or any political subdivision thereof
      or otherwise had some connection with the relevant taxing jurisdiction
      other than by reason of the mere ownership of, or receipt of payment
      under,


                                       65
<PAGE>

      such Security; (B) presented such Security for payment in the relevant
      taxing jurisdiction or any political subdivision thereof, unless such
      Security could not have been presented for payment elsewhere; or (C)
      presented such Security more than thirty (30) days after the date on which
      the payment in respect of such Security first became due and payable or
      provided for, whichever is later, except to the extent that the Holder
      would have been entitled to such Additional Amounts if it had presented
      such Security for payment on any day within such period of thirty (30)
      days;

            (2) any estate, inheritance, gift, sale, transfer, personal property
      or similar tax, assessment or other governmental charge;

            (3) any tax, assessment or other governmental charge that is imposed
      or withheld by reason of the failure by the Holder or the beneficial owner
      of such Security to comply with any reasonable request by the Company
      addressed to the Holder within 90 days of such request (A) to provide
      information concerning the nationality, residence or identity of the
      Holder or such beneficial owner or (B) to make any declaration or other
      similar claim or satisfy any information or reporting requirement, which,
      in the case of (A) or (B), is required or imposed by statute, treaty,
      regulation or administrative practice of the relevant taxing jurisdiction
      or any political subdivision thereof as a precondition to exemption from
      all or part of such tax, assessment or other governmental charge; or

            (4) any combination of items (1), (2) and (3);

nor shall Additional Amounts be paid with respect to any payment of the
principal of, or premium, if any, interest or any other amounts on, any such
Security to any Holder who is a fiduciary or partnership or other than the sole
beneficial owner of such Security to the extent such payment would be required
by the laws of the relevant taxing jurisdiction (or any political subdivision or
relevant taxing authority thereof or therein) to be included in the income for
tax purposes of a beneficiary or partner or settlor with respect to such
fiduciary or a member of such partnership or a beneficial owner who would not
have been entitled to such Additional Amounts had it been the Holder of the
Security.

      Whenever in this Indenture there is mentioned, in any context, the payment
of the principal of or any premium, interest or any other amounts on, or in
respect of, any Security of any series or any Coupon or the net proceeds
received on the sale or exchange of any Security of any series, such mention
shall be deemed to include mention of the payment of Additional Amounts provided
by the terms of such series established hereby or pursuant hereto to the extent
that, in such context, Additional Amounts are, were or would be payable in
respect thereof pursuant to such terms, and express mention of the payment of
Additional Amounts (if applicable) in any provision hereof shall not be
construed as excluding the payment of Additional Amounts in those provisions
hereof where such express mention is not made.

      Except as otherwise provided in or pursuant to this Indenture or the
Securities of the applicable series, at least 10 days prior to the first
Interest Payment Date with respect to a series of Securities (or if the
Securities of such series shall not bear interest prior to Maturity, the first
day on which a payment of principal is made), and at least 10 days prior to each
date of payment of principal or interest if there has been any change with
respect to the matters set forth in the


                                       66
<PAGE>

below-mentioned Officer's Certificate, the Company shall furnish to the Trustee
and the principal Paying Agent or Paying Agents, if other than the Trustee, an
Officer's Certificate instructing the Trustee and such Paying Agent or Paying
Agents whether such payment of principal of and premium, if any, interest or any
other amounts on the Securities of such series shall be made to Holders of
Securities of such series or the Coupons appertaining thereto without
withholding for or on account of any tax, fee, duty, assessment or other
governmental charge described in this Section 10.4. If any such withholding
shall be required, then such Officer's Certificate shall specify by taxing
jurisdiction the amount, if any, required to be withheld on such payments to
such Holders of Securities or Coupons, and the Company agrees to pay to the
Trustee or such Paying Agent the Additional Amounts required by this Section
10.4. The Company covenants to indemnify the Trustee and any Paying Agent for,
and to hold them harmless against, any loss, liability or expense reasonably
incurred without negligence or bad faith on their part arising out of or in
connection with actions taken or omitted by any of them in reliance on any
Officer's Certificate furnished pursuant to this Section 10.4.

      Section 10.5. Corporate Existence.

      Subject to Article 8, the Company shall do or cause to be done all things
necessary to preserve and keep in full force and effect its corporate existence
and that of each of its Subsidiaries and their respective rights (charter and
statutory) and franchises; provided, however, that the foregoing shall not
obligate the Company or any of its Subsidiaries to preserve any such right or
franchise if the Company or any such Subsidiary shall determine that the
preservation thereof is no longer desirable in the conduct of its business or
the business of such Subsidiary and that the loss thereof is not disadvantageous
in any material respect to any Holder.

      Section 10.6. Waiver of Certain Covenants.

      The Company may omit in any particular instance to comply with any term,
provision or condition set forth in Section 10.5 with respect to the Securities
of any series if before the time for such compliance the Holders of at least a
majority in principal amount of the Outstanding Securities of such series, by
Act of such Holders, either shall waive such compliance in such instance or
generally shall have waived compliance with such term, provision or condition,
but no such waiver shall extend to or affect such term, provision or condition
except to the extent so expressly waived, and, until such waiver shall become
effective, the obligations of the Company and the duties of the Trustee in
respect of any such term, provision or condition shall remain in full force and
effect.

      Section 10.7. Company Statement as to Compliance; Notice of Certain
Defaults.

      (1) The Company shall deliver to the Trustee, within 120 days after the
end of each fiscal year, a written statement (which need not be contained in or
accompanied by an Officer's Certificate) signed by the principal executive
officer, the principal financial officer or the principal accounting officer of
the Company, stating that

            (a) a review of the activities of the Company during such year and
      of its performance under this Indenture has been made under his or her
      supervision, and


                                       67
<PAGE>

            (b) to the best of his or her knowledge, based on such review, (a)
      the Company has complied with all the conditions and covenants imposed on
      it under this Indenture throughout such year, or, if there has been a
      default in the fulfillment of any such condition or covenant, specifying
      each such default known to him or her and the nature and status thereof,
      and (b) no event has occurred and is continuing which is, or after notice
      or lapse of time or both would become, an Event of Default, or, if such an
      event has occurred and is continuing, specifying each such event known to
      him and the nature and status thereof.

            (c) The Company shall deliver to the Trustee, within five days after
      the occurrence thereof, written notice of any Event of Default or any
      event which after notice or lapse of time or both would become an Event of
      Default pursuant to clause (4) of Section 5.1.

            (d) The Trustee shall have no duty to monitor the Company's
      compliance with the covenants contained in this Article 10 other than as
      specifically set forth in this Section 10.7.

                                   ARTICLE 11

                            REDEMPTION OF SECURITIES

      Section 11.1. Applicability of Article.

      Redemption of Securities of any series at the option of the Company as
permitted or required by the terms of such Securities shall be made in
accordance with the terms of such Securities and (except as otherwise provided
herein or pursuant hereto) this Article.

      Section 11.2. Election to Redeem; Notice to Trustee.

      The election of the Company to redeem any Securities shall be evidenced by
or pursuant to a Board Resolution. In case of any redemption at the election of
the Company of (a) less than all of the Securities of any series or (b) all of
the Securities of any series, with the same issue date, interest rate or
formula, Stated Maturity and other terms, the Company shall, at least 60 days
prior to the Redemption Date fixed by the Company (unless a shorter notice shall
be satisfactory to the Trustee), notify the Trustee of such Redemption Date and
of the principal amount of Securities of such series to be redeemed.

      Section 11.3. Selection by Trustee of Securities to be Redeemed.

      If less than all of the Securities of any series with the same issue date,
interest rate or formula, Stated Maturity and other terms are to be redeemed,
the particular Securities to be redeemed shall be selected not more than 60 days
prior to the Redemption Date by the Trustee from the Outstanding Securities of
such series not previously called for redemption, by such method as the Trustee
shall deem fair and appropriate and which may provide for the selection


                                       68
<PAGE>

for redemption of portions of the principal amount of Registered Securities of
such series; provided, however, that no such partial redemption shall reduce the
portion of the principal amount of a Registered Security of such series not
redeemed to less than the minimum denomination for a Security of such series
established herein or pursuant hereto.

      The Trustee shall promptly notify the Company and the Security Registrar
(if other than itself) in writing of the Securities selected for redemption and,
in the case of any Securities selected for partial redemption, the principal
amount thereof to be redeemed.

      For all purposes of this Indenture, unless the context otherwise requires,
all provisions relating to the redemption of Securities shall relate, in the
case of any Securities redeemed or to be redeemed only in part, to the portion
of the principal of such Securities which has been or is to be redeemed.

      Unless otherwise specified in or pursuant to this Indenture or the
Securities of any series, if any Security selected for partial redemption is
converted into Common Stock of the Company or exchanged for other securities in
part before termination of the conversion or exchange right with respect to the
portion of the Security so selected, the converted portion of such Security
shall be deemed (so far as may be) to be the portion selected for redemption.
Securities which have been converted or exchanged during a selection of
Securities to be redeemed shall be treated by the Trustee as Outstanding for the
purpose of such selection.

      Section 11.4. Notice of Redemption.

      Notice of redemption shall be given in the manner provided in Section 1.6,
not less than 30 nor more than 60 days prior to the Redemption Date, unless a
shorter period is specified in the Securities to be redeemed, to the Holders of
Securities to be redeemed. Failure to give notice by mailing in the manner
herein provided to the Holder of any Registered Securities designated for
redemption as a whole or in part, or any defect in the notice to any such
Holder, shall not affect the validity of the proceedings for the redemption of
any other Securities or portion thereof.

      Any notice that is mailed to the Holder of any Registered Securities in
the manner herein provided shall be conclusively presumed to have been duly
given, whether or not such Holder receives the notice.

      All notices of redemption shall state:

      (1) the Redemption Date,

      (2) the Redemption Price,

      (3) if less than all Outstanding Securities of any series are to be
redeemed, the identification (and, in the case of partial redemption, the
principal amount) of the particular Security or Securities to be redeemed,

      (4) in case any Security is to be redeemed in part only, the notice which
relates to such Security shall state that on and after the Redemption Date, upon
surrender of such Security,


                                       69
<PAGE>

the Holder of such Security will receive, without charge, a new Security or
Securities of authorized denominations for the principal amount thereof
remaining unredeemed,

      (5) that, on the Redemption Date, the Redemption Price shall become due
and payable upon each such Security or portion thereof to be redeemed, and, if
applicable, that interest thereon shall cease to accrue on and after said date,

      (6) the place or places where such Securities, together (in the case of
Bearer Securities) with all Coupons appertaining thereto, if any, maturing after
the Redemption Date, are to be surrendered for payment of the Redemption Price
and any accrued interest and Additional Amounts pertaining thereto,

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

      (8) that, unless otherwise specified in such notice, Bearer Securities of
any series, if any, surrendered for redemption must be accompanied by all
Coupons maturing subsequent to the date fixed for redemption or the amount of
any such missing Coupon or Coupons will be deducted from the Redemption Price,
unless security or indemnity satisfactory to the Company, the Trustee and any
Paying Agent is furnished,

      (9) if Bearer Securities of any series are to be redeemed and no
Registered Securities of such series are to be redeemed, and if such Bearer
Securities may be exchanged for Registered Securities not subject to redemption
on the Redemption Date pursuant to Section 3.5 or otherwise, the last date, as
determined by the Company, on which such exchanges may be made,

      (10) in the case of Securities of any series that are convertible into
Common Stock of the Company or exchangeable for other securities, the conversion
or exchange price or rate, the date or dates on which the right to convert or
exchange the principal of the Securities of such series to be redeemed will
commence or terminate and the place or places where such Securities may be
surrendered for conversion or exchange, and

      (11) the CUSIP number or the Euroclear or the Cedel reference numbers of
such Securities, if any (or any other numbers used by a Depository to identify
such Securities).

      A notice of redemption published as contemplated by Section 1.6 need not
identify particular Registered Securities to be redeemed.

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

      Section 11.5. Deposit of Redemption Price.

      On or prior to any Redemption Date, the Company shall deposit, with
respect to the Securities of any series called for redemption pursuant to
Section 11.4, 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 10.3) an amount of money in the applicable Currency sufficient to pay
the Redemption Price of, and (except if the Redemption Date shall be an Interest
Payment Date,


                                       70
<PAGE>

unless otherwise specified pursuant to Section 3.1 or in the Securities of such
series) any accrued interest on and Additional Amounts with respect thereto, all
such Securities or portions thereof which are to be redeemed on that date.

      Section 11.6. Securities Payable on Redemption Date.

      Notice of redemption having been given as aforesaid, the Securities 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
interest) such Securities shall cease to bear interest and the Coupons for such
interest appertaining to any Bearer Securities so to be redeemed, except to the
extent provided below, shall be void. Upon surrender of any such Security for
redemption in accordance with said notice, together with all Coupons, if any,
appertaining thereto maturing after the Redemption Date, such Security shall be
paid by the Company at the Redemption Price, together with any accrued interest
and Additional Amounts to the Redemption Date; provided, however, that, except
as otherwise provided in or pursuant to this Indenture or the Bearer Securities
of such series, installments of interest on Bearer Securities whose Stated
Maturity is on or prior to the Redemption Date shall be payable only upon
presentation and surrender of Coupons for such interest (at an Office or Agency
located outside the United States except as otherwise provided in Section 10.2),
and provided, further, that, except as otherwise specified in or pursuant to
this Indenture or the Registered Securities of such series, installments of
interest on Registered Securities whose Stated Maturity is on or prior to the
Redemption Date shall be payable to the Holders of such Securities, or one or
more Predecessor Securities, registered as such at the close of business on the
Regular Record Dates therefor according to their terms and the provisions of
Section 3.7.

      If any Bearer Security surrendered for redemption shall not be accompanied
by all appurtenant Coupons maturing after the Redemption Date, such Security may
be paid after deducting from the Redemption Price an amount equal to the face
amount of all such missing Coupons, or the surrender of such missing Coupon or
Coupons may be waived by the Company and the Trustee if there be furnished to
them such security or indemnity as they may require to save each of them and any
Paying Agent harmless. If thereafter the Holder of such Security shall surrender
to the Trustee or any Paying Agent any such missing Coupon in respect of which a
deduction shall have been made from the Redemption Price, such Holder shall be
entitled to receive the amount so deducted; provided, however, that any interest
or Additional Amounts represented by Coupons shall be payable only upon
presentation and surrender of those Coupons at an Office or Agency for such
Security located outside of the United States except as otherwise provided in
Section 10.2.

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

      Section 11.7. Securities Redeemed in Part.

      Any Registered Security which is to be redeemed only in part shall be
surrendered at any Office or Agency for such Security (with, if the Company or
the Trustee so requires, due


                                       71
<PAGE>

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 deliver to the Holder of such Security without service charge,
a new Registered Security or Securities of the same series, containing identical
terms and provisions, 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 Security so surrendered. If a Security in global
form is so surrendered, the Company shall execute, and the Trustee shall
authenticate and deliver to the U.S. Depository or other Depository for such
Security in global form as shall be specified in the Company Order with respect
thereto to the Trustee, without service charge, a new Security in global form in
a denomination equal to and in exchange for the unredeemed portion of the
principal of the Security in global form so surrendered.

                                   ARTICLE 12

                                  SINKING FUNDS

      Section 12.1. Applicability of Article.

      The provisions of this Article shall be applicable to any sinking fund for
the retirement of Securities of a series, except as otherwise permitted or
required in or pursuant to this Indenture or any Security of such series issued
pursuant to this Indenture.

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

      Section 12.2. Satisfaction of Sinking Fund Payments with Securities.

      The Company may, in satisfaction of all or any part of any sinking fund
payment with respect to the Securities of any series to be made pursuant to the
terms of such Securities (1) deliver Outstanding Securities of such series
(other than any of such Securities previously called for redemption or any of
such Securities in respect of which cash shall have been released to the
Company), together in the case of any Bearer Securities of such series with all
unmatured Coupons appertaining thereto, and (2) apply as a credit Securities of
such series which have been redeemed either at the election of the Company
pursuant to the terms of such series of Securities or through the application of
permitted optional sinking fund payments pursuant to the terms of such
Securities, provided that such series of Securities have not been previously so
credited. Such Securities shall be received and credited for such purpose by the
Trustee at the Redemption Price specified in such Securities for redemption
through operation of the sinking fund and the amount of such sinking fund
payment shall be reduced accordingly. If, as a result of the delivery or credit
of Securities of any series in lieu of cash payments pursuant to this Section
12.2, the


                                       72
<PAGE>

principal amount of Securities of such series to be redeemed in order to satisfy
the remaining sinking fund payment shall be less than $100,000, the Trustee need
not call Securities of such series for redemption, except upon Company Request,
and such cash payment shall be held by the Trustee or a Paying Agent and applied
to the next succeeding sinking fund payment, provided, however, that the Trustee
or such Paying Agent shall at the request of the Company from time to time pay
over and deliver to the Company any cash payment so being held by the Trustee or
such Paying Agent upon delivery by the Company to the Trustee of Securities of
that series purchased by the Company having an unpaid principal amount equal to
the cash payment requested to be released to the Company.

      Section 12.3. Redemption of Securities for Sinking Fund.

      Not less than 75 days prior to each sinking fund payment date for any
series of Securities, the Company shall deliver to the Trustee an Officer's
Certificate specifying the amount of the next ensuing mandatory sinking fund
payment for that series pursuant to the terms of that series, the portion
thereof, if any, which is to be satisfied by payment of cash and the portion
thereof, if any, which is to be satisfied by delivering and crediting of
Securities of that series pursuant to Section 12.2, and the optional amount, if
any, to be added in cash to the next ensuing mandatory sinking fund payment, and
will also deliver to the Trustee any Securities to be so credited and not
theretofore delivered. If such Officer's Certificate shall specify an optional
amount to be added in cash to the next ensuing mandatory sinking fund payment,
the Company shall thereupon be obligated to pay the amount therein specified.
Not less than 60 days before each such sinking fund payment date the Trustee
shall select the Securities to be redeemed upon such sinking fund payment date
in the manner specified in Section 11.3 and cause notice of the redemption
thereof to be given in the name of and at the expense of the Company in the
manner provided in Section 11.4. Such notice having been duly given, the
redemption of such Securities shall be made upon the terms and in the manner
stated in Sections 11.6 and 11.7.

                                   ARTICLE 13

                       REPAYMENT AT THE OPTION OF HOLDERS

      Section 13.1. Applicability of Article.

      Securities of any series which are repayable at the option of the Holders
thereof before their Stated Maturity shall be repaid in accordance with the
terms of the Securities of such series. The repayment of any principal amount of
Securities pursuant to such option of the Holder to require repayment of
Securities before their Stated Maturity, for purposes of Section 3.9, shall not
operate as a payment, redemption or satisfaction of the Indebtedness represented
by such Securities unless and until the Company, at its option, shall deliver or
surrender the same to the Trustee with a directive that such Securities be
cancelled. Notwithstanding anything to the contrary contained in this Section
13.1, in connection with any repayment of Securities, the Company may arrange
for the purchase of any Securities by an agreement with one or more investment
bankers or other purchasers to purchase such Securities by paying to the Holders
of such Securities on or before the close of business on the repayment date an
amount not less than the repayment price payable by the Company on repayment of
such Securities, and the obligation


                                       73
<PAGE>

of the Company to pay the repayment price of such Securities shall be satisfied
and discharged to the extent such payment is so paid by such purchasers.

                                   ARTICLE 14

                        SECURITIES IN FOREIGN CURRENCIES

      Section 14.1. Applicability of Article.

      Whenever this Indenture provides for (i) any action by, or the
determination of any of the rights of, Holders of Securities of any series in
which not all of such Securities are denominated in the same Currency, or (ii)
any distribution to Holders of Securities, in the absence of any provision to
the contrary in the form of Security of any particular series or pursuant to
this Indenture or the Securities, any amount in respect of any Security
denominated in a Currency other than Dollars shall be treated for any such
action or distribution as that amount of Dollars that could be obtained for such
amount on such reasonable basis of exchange and as of the record date with
respect to Registered Securities of such series (if any) for such action,
determination of rights or distribution (or, if there shall be no applicable
record date, such other date reasonably proximate to the date of such action,
determination of rights or distribution) as the Company may specify in a written
notice to the Trustee.

                                   ARTICLE 15

      Section 15.1. Purposes for Which Meetings May Be Called.

      A meeting of Holders of Securities of any series may be called at any time
and from time to time pursuant to this Article to make, give or take any

provided by this Indenture to be made, given or taken by Holders of Securities
of such series.

      Section 15.2. Call, Notice and Place of Meetings.

      (1) The Trustee may at any time call a meeting of Holders of Securities of
any series for any purpose specified in Section 15.1, to be held at such time
and at such place in the Borough of Manhattan, The City of New York, or, if
Securities of such series have been issued in whole or in part as Bearer
Securities, in London or in such place outside the United States as the Trustee
shall determine. Notice of every meeting of Holders of Securities of any series,
setting forth the time and the place of such meeting and in general terms the
action proposed to be taken at such meeting, shall be given, in the manner
provided in Section 1.6, not less than 21 nor more than 180 days prior to the
date fixed for the meeting.

      (2) In case at any time the Company (by or pursuant to a Board Resolution)
or the Holders of at least 10% in principal amount of the Outstanding Securities
of any series shall have requested the Trustee to call a meeting of the Holders
of Securities of such series for any purpose specified in Section 15.1, by
written request setting forth in reasonable detail the action proposed to be
taken at the meeting, and the Trustee shall not have mailed notice of or made
the first


                                       74
<PAGE>

publication of the notice of such meeting within 21 days after receipt of such
request (whichever shall be required pursuant to Section 1.6) or shall not
thereafter proceed to cause the meeting to be held as provided herein, then the
Company or the Holders of Securities of such series in the amount above
specified, as the case may be, may determine the time and the place in the
Borough of Manhattan, The City of New York, or, if Securities of such series are
to be issued as Bearer Securities, in London for such meeting and may call such
meeting for such purposes by giving notice thereof as provided in clause (1) of
this Section.

      Section 15.3. Persons Entitled to Vote at Meetings.

      To be entitled to vote at any meeting of Holders of Securities of any
series, a Person shall be (1) a Holder of one or more Outstanding Securities of
such series, or (2) a Person appointed by an instrument in writing as proxy for
a Holder or Holders of one or more Outstanding Securities of such series by such
Holder or Holders. The only Persons who shall be entitled to be present or to
speak at any meeting of Holders of Securities of any series shall be the Persons
entitled to vote at such meeting and their counsel, any representatives of the
Trustee and its counsel and any representatives of the Company and its counsel.

      Section 15.4. Quorum; Action.

      The Persons entitled to vote a majority in principal amount of the
Outstanding Securities of a series shall constitute a quorum for any meeting of
Holders of Securities of such series. In the absence of a quorum within 30
minutes after the time appointed for any such meeting, the meeting shall, if
convened at the request of Holders of Securities of such series, be dissolved.
In any other case the meeting may be adjourned for a period of not less than 10
days as determined by the chairman of the meeting prior to the adjournment of
such meeting. In the absence of a quorum at any reconvened meeting, such
reconvened meeting may be further adjourned for a period of not less than 10

such reconvened meeting. Notice of the reconvening of any adjourned meeting
shall be given as provided in Section 15.2(1), except that such notice need be

is scheduled to be reconvened. Notice of the reconvening of an adjourned meeting
shall state expressly the percentage, as provided above, of the principal amount
of the Outstanding Securities of such series which shall constitute a quorum.

      Except as limited by the proviso to Section 9.2, any resolution presented
to a meeting or adjourned meeting duly reconvened at which a quorum is present
as aforesaid may be adopted only by the affirmative vote of the Holders of a
majority in principal amount of the Outstanding Securities of that series;
provided, however, that, except as limited by the proviso to Section 9.2, any

      Any resolution passed or decision taken at any meeting of Holders of
Securities of any series duly held in accordance with this Section shall be
binding on all the Holders of Securities of such series and the Coupons
appertaining thereto, whether or not such Holders were present or represented at
the meeting.

      Section 15.5. Determination of Voting Rights; Conduct and Adjournment of
Meetings.

      (1) Notwithstanding any other provisions of this Indenture, the Trustee
may make such reasonable regulations as it may deem advisable for any meeting of
Holders of Securities of such series in regard to proof of the holding of
Securities of such series and of the appointment of proxies and in regard to the
appointment and duties of inspectors of votes, the submission and examination of
proxies, certificates and other evidence of the right to vote, and such other
matters concerning the conduct of the meeting as it shall deem appropriate.
Except as otherwise permitted or required by any such regulations, the holding
of Securities shall be proved in the manner specified in Section 1.4 and the
appointment of any proxy shall be proved in the manner specified in Section 1.4
or by having the signature of the person executing the proxy witnessed or
guaranteed by any trust company, bank or banker authorized by Section 1.4 to
certify to the holding of Bearer Securities. Such regulations may provide that
written instruments appointing proxies, regular on their face, may be presumed
valid and genuine without the proof specified in Section 1.4 or other proof.

      (2) The Trustee shall, by an instrument in writing, appoint a temporary
chairman of the meeting, unless the meeting shall have been called by the
Company or by Holders of Securities as provided in Section 15.2(2), in which
case the Company or the Holders of Securities of the series calling the meeting,
as the case may be, shall in like manner appoint a temporary chairman. A
permanent chairman and a permanent secretary of the meeting shall be elected by
vote of the Persons entitled to vote a majority in principal amount of the
Outstanding Securities of such series represented at the meeting.

      (3) At any meeting, each Holder of a Security of such series or proxy
shall be entitled to one vote for each $1,000 principal amount of Securities of
such series held or represented by him; provided, however, that no vote shall be
cast or counted at any meeting in respect of any Security challenged as not
Outstanding and ruled by the chairman of the meeting to be not Outstanding. The
chairman of the meeting shall have no right to vote, except as a Holder of a
Security of such series or proxy.

      (4) Any meeting of Holders of Securities of any series duly called
pursuant to Section 15.2 at which a quorum is present may be adjourned from time
to time by Persons entitled to vote a majority in principal amount of the
Outstanding Securities of such series represented at the meeting; and the
meeting may be held as so adjourned without further notice.

      Section 15.6. Counting Votes and Recording Action of Meetings.

      The vote upon any resolution submitted to any meeting of Holders of
Securities of any series shall be by written ballots on which shall be
subscribed the signatures of the Holders of Securities of such series or of
their representatives by proxy and the principal amounts and serial numbers of
the Outstanding Securities of such series held or represented by them. The


                                       76
<PAGE>

permanent chairman of the meeting shall appoint two inspectors of votes who
shall count all votes cast at the meeting for or against any resolution and who
shall make and file with the secretary of the meeting their verified written
reports in triplicate of all votes cast at the meeting. A record, at least in
triplicate, of the proceedings of each meeting of Holders of Securities of any
series shall be prepared by the secretary of the meeting and there shall be
attached to said record the original reports of the inspectors of votes on any
vote by ballot taken thereat and affidavits by one or more persons having
knowledge of the facts setting forth a copy of the notice of the meeting and
showing that said notice was given as provided in Section 15.2 and, if
applicable, Section 15.4. Each copy shall be signed and verified by the
affidavits of the permanent chairman and secretary of the meeting and one such
copy shall be delivered to the Company, and another to the Trustee to be
preserved by the Trustee, the latter to have attached thereto the ballots voted
at the meeting. Any record so signed and verified shall be conclusive evidence
of the matters therein stated.

                                   ARTICLE 16

                           SUBORDINATION OF SECURITIES

      Section 16.1. Agreement to Subordinate.

      The Company covenants and agrees, and each Holder of Securities issued
hereunder and under any indenture supplemental hereto or pursuant to a Board
Resolution and Officer's Certificate ("Additional Provisions") by such Holder's
acceptance thereof likewise covenants and agrees, that all Securities shall be
issued subject to the provisions of this Article 16; and each Holder of a
Security, 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, any premium and interest
on and any Additional Amounts with respect to all Securities of each series
issued hereunder and under any Additional Provisions shall, to the extent and in
the manner hereinafter set forth, be subordinate in right of payment to the
prior payment in full of all Senior Indebtedness with respect to such series,
whether outstanding at the date of this Indenture or thereafter incurred.

      No provision of this Article 16 shall prevent the occurrence of any
default or Event of Default hereunder.

      Section 16.2. 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 amount due on any
Senior Indebtedness with respect to the Securities of any series, or in the
event that the maturity of any Senior Indebtedness with respect to the
Securities of any series has been accelerated because of a default, then, in
either case, no payment shall be made by the Company with respect to the
principal (including redemption and sinking fund payments) of, any premium or
interest on, or any Additional Amounts with respect to, the Securities of such
series.

      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 16.2, such


                                       77
<PAGE>

payment shall be held in trust for the benefit of, and shall be paid over or
delivered to, the holders of such 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 such 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 such Senior Indebtedness and only the amounts specified in such
notice to the Trustee shall be paid to the holders of such Senior Indebtedness.

      Section 16.3. 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 dissolution, winding-up, liquidation or reorganization of the Company,
whether voluntary or involuntary, or in bankruptcy, insolvency, receivership or
other proceedings, all amounts due upon all Senior Indebtedness with respect to
the Securities of any series shall first be paid in full, or payment thereof
provided for in money in accordance with its terms, before any payment is made
by the Company on account of the principal of, premium or interest on, or
Additional Amounts with respect to, the Securities of such series; and upon any
such dissolution, winding-up, liquidation or reorganization, or in any such
bankruptcy, insolvency, receivership or other proceeding, 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 or the Trustee
would be entitled to receive from the Company, except for the provisions of this
Article 16, 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 or by the Trustee under this Indenture if
received by them or it, directly to the holders of such Senior Indebtedness (pro
rata to such holders on the basis of the respective amounts of such 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 the Securities of such series 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 before all such 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 such 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,
as their respective interests may appear, as calculated by the Company, for
application to the payment of all such 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 benefit of the holders of such Senior Indebtedness.


                                       78

      For purposes of this Article 16, 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 16 with respect to
the Securities of the relevant series to the payment of all Senior Indebtedness
with respect to the Securities of such series that 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 into, another
Person or the liquidation or dissolution of the Company following the
conveyance, transfer or lease of its property as an entirety, or substantially
as an entirety, to another Person upon the terms and conditions provided for in
Article 8 of this Indenture shall not be deemed a dissolution, winding-up,
liquidation or reorganization for the purposes of this Section 16.3 if such
other Person shall, as a part of such consolidation, merger, conveyance or
transfer, comply with the conditions stated in Article 8 of this Indenture.
Nothing in Section 16.2 or in this Section 16.3 shall apply to claims of, or
payments to, the Trustee under or pursuant to Section 6.6 of this Indenture.

      Section 16.4. Subrogation.

      Subject to the payment in full of all Senior Indebtedness with respect to
the Securities of any series, the rights of the Holders of the Securities of
such series 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 applicable to such Senior Indebtedness until the
principal of, any premium and interest on, and any Additional Amounts with
respect to, the Securities of such series 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 or the Trustee would be entitled except for the provisions of this
Article 16, and no payment over pursuant to the provisions of this Article 16 to
or for the benefit of the holders of such Senior Indebtedness by Holders of the
Securities of such series or the Trustee, shall, as between the Company, its
creditors other than holders of such Senior Indebtedness, and the Holders of the
Securities of such series, 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 16 are and are intended solely for the purposes of defining the
relative rights of the Holders of the Securities of each series, on the one
hand, and the holders of the Senior Indebtedness with respect to the Securities
of such series on the other hand.

      Nothing contained in this Article 16 or elsewhere in this Indenture, any
Additional Provisions or in the Securities of any series is intended to or shall
impair, as between the Company, its creditors other than the holders of Senior
Indebtedness with respect to the Securities of such series, and the Holders of
the Securities of such series, the obligation of the Company, which is absolute
and unconditional, to pay to the Holders of the Securities of such series the
principal of, any premium and interest on, and any Additional Amounts with
respect to, the Securities of such series 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 Securities of such series and
creditors of the Company, other than the holders of such Senior Indebtedness,
nor shall anything herein or therein prevent the Trustee or the Holder of any


                                       79
<PAGE>

Security of such series from exercising all remedies otherwise permitted by
applicable law upon default under this Indenture, subject to the rights, if any,
under this Article 16 of the holders of such Senior Indebtedness in respect of
cash, property or securities of the Company, as the case may be, received upon
the exercise of any such remedy.

      Upon any payment or distribution of assets of the Company referred to in
this Article 16, the Trustee, subject to the provisions of Article 6 of this
Indenture, and the Holders shall be entitled to conclusively 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 Securities of any series, for the purposes of ascertaining
the Persons entitled to participate in such distribution, the holders of Senior
Indebtedness with respect to the Securities of such series 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 16.

      Section 16.5. Trustee to Effectuate Subordination.

      Each Holder of Securities 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 16 and appoints the Trustee such Holder's attorney-in-fact for any and
all such purposes.

      Section 16.6. 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 that would prohibit the making of
any payment of monies to or by the Trustee in respect of the Securities of any
series pursuant to the provisions of this Article 16. Notwithstanding the
provisions of this Article 16 or any other provision of this Indenture or any
Additional Provisions, the Trustee shall not be charged with knowledge of the
existence of any facts that would prohibit the making of any payment of monies
to or by the Trustee in respect of the Securities of any series pursuant to the
provisions of this Article 16, unless and until a Responsible Officer of the
Trustee shall have received written notice thereof from the Company or a holder
or holders of Senior Indebtedness with respect to the Securities of such series
or from any trustee therefor; and before the receipt of any such written notice,
the Trustee, subject to the provisions of Article 6 of this Indenture, 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 16.6 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, any premium or interest on, or any
Additional Amounts with respect to, any Security of such series), 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 that may be received by it within two Business Days prior to such date.


                                       80
<PAGE>

      The Trustee, subject to the provisions of Article 6 of this Indenture,
shall be entitled to conclusively rely on the delivery to it of a written notice
by a Person representing himself to be a holder of Senior Indebtedness with
respect to the Securities of any series (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 such Senior Indebtedness to
participate in any payment or distribution pursuant to this Article 16, the
Trustee may request such Person to furnish evidence to the reasonable
satisfaction of the Trustee as to the amount of such 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 rights of such
Person under this Article 16, 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.

      Upon any payment or distribution of assets of the Company referred to in
this Article 16, the Trustee and the Holders shall be entitled to rely upon any
order or decree entered by any court of competent jurisdiction in which such
insolvency, bankruptcy, receivership, liquidation, reorganization, dissolution,
winding-up or similar case or proceeding is pending, or a certificate of the
trustee in bankruptcy, liquidating trustee, custodian, receiver, assignee for
the benefit of creditors, agent or other Person making such payment or
distribution, delivered to the Trustee or to the Holders of the Securities of
any series, for the purpose of ascertaining the Persons entitled to participate
in such payment or distribution, the holders of Senior Indebtedness with respect
to the Securities of such series and other indebtedness of the Company, the
amount thereof or payable thereon, the amount or amounts paid or distributed
thereon and all other facts pertinent thereto or to this Article 16.

      Section 16.7. 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 16 in respect of any Senior Indebtedness with respect
to the Securities of any series at any time held by it, to the same extent as
any other holder of such Senior Indebtedness, and nothing in this Indenture or
any Additional Provisions shall deprive the Trustee of any of its rights as such
holder.

      With respect to the holders of Senior Indebtedness with respect to the
Securities of any series, the Trustee undertakes to perform or to observe only
such of its covenants and obligations as are specifically set forth in this
Article 16, and no implied covenants or obligations with respect to the holders
of such Senior Indebtedness shall be read into this Indenture or any Additional
Provisions 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 Article 6 of this Indenture, the Trustee shall not be liable to
any holder of such Senior Indebtedness if it shall pay over or deliver to
Holders of the Securities of such series, 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 16 or otherwise.

      Nothing in this Article 16 shall apply to claims of, or payments to, the
Trustee under or pursuant to Section 6.6.


                                       81

      Section 16.8. 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 that 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 with respect to the Securities of any series may,
at any time and from time to time, without the consent of or notice to the
Trustee or the Holders of Securities of such series, without incurring
responsibility to such Holders and without impairing or releasing the
subordination provided in this Article 16 or the obligations hereunder of the
Holders of the Securities of such series to the holders of such 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.

                                    * * * * *

      provide its proxy or proxies to the beneficial owners of interests in any
      such global Security through such U.S. Depository's standing instructions
      and customary practices.

      proxies, and only such Persons, shall be entitled to make, give or take
      such request, demand, authorization, direction, notice, consent, waiver or
      other Act, whether or not such Holders remain Holders after such record
      date. No such request, demand, authorization, direction, notice, consent,
      waiver or other Act shall be valid or effective if made, given or taken

      Securities held by any Person, and the date of the commencement and the

<PAGE>

      Securities or by a certificate executed, as depositary, by any trust
      company, bank, banker or other depositary reasonably acceptable to the
      Company and the Guarantor, wherever situated, if such certificate shall be
      deemed by the Company, the Guarantor and the Trustee to be satisfactory,
      showing that at the date therein mentioned such Person had on deposit with
      such depositary, or exhibited to it, the Bearer Securities therein
      described; or such facts may be proved by the certificate or affidavit of
      the Person holding such Bearer Securities, if such certificate or
      affidavit is deemed by the Trustee to be satisfactory. The Trustee, the
      Company and the Guarantor may assume that such ownership of any Bearer
      Security continues until (i) another certificate or affidavit bearing a
      later date issued in respect of the same Bearer Security is produced, or
      (ii) such Bearer Security is produced to the Trustee by some other Person,
      or (iii) such Bearer Security is surrendered in exchange for a Registered
      Security, or (iv) such Bearer Security is no longer Outstanding. The
      ownership, principal amount and serial numbers of Bearer Securities held
      by the Person so executing such instrument or writing and the date of the
      commencement and the date of the termination of holding the same may also
      be proved in any other manner which the Company, the Guarantor and the
      Trustee deem sufficient.

            (5) If the Company or the Guarantor shall solicit from the Holders
      of any Registered Securities any request, demand, authorization,
      direction, notice, consent, waiver or other Act, the Company or the
      Guarantor, as the case may be, may at its option (but is not obligated
      to), by Board Resolution or Guarantor's Board Resolution, as the case may
      be, fix in advance a record date for the determination of Holders of
      Registered Securities entitled to give such request, demand,
      authorization, direction, notice, consent, waiver or other Act. If such a
      record date is fixed, such request, demand, authorization, direction,
      notice, consent, waiver or other Act may be given before or after such
      record date, but only the Holders of Registered Securities of record at
      the close of business on such record date shall be deemed to be Holders
      for the purpose of determining whether Holders of the requisite proportion
      of Outstanding Securities have authorized or agreed or consented to such
      request, demand, authorization, direction, notice, consent, waiver or

      Section 1.5. Notices, etc. to Trustee, Company and Guarantor.

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

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

            (2) the Company or the Guarantor, as the case may be, by the Trustee
      or 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 or the Guarantor, as the case may be,
      addressed to the attention of its Treasurer, with a copy to the attention
      of its General Counsel, 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 or the
      Guarantor, as the case may be.

      Section 1.6. Notice to Holders of Securities; Waiver.

      Except as otherwise expressly provided in or pursuant to this Indenture,
where this Indenture provides for notice to Holders of Securities of any event,

            (1) such notice shall be sufficiently given to Holders of Registered
      Securities if in writing and mailed, first-class postage prepaid, to each
      Holder of a Registered Security affected by such event, at his address as
      it appears in the Security Register, not later than the latest date, and
      not earlier than the earliest date, prescribed for the giving of such
      notice; and

            (2) such notice shall be sufficiently given to Holders of Bearer
      Securities, if any, if published in an Authorized Newspaper in The City of
      New York and, if such Securities are then listed on any stock exchange
      outside the United States, in an Authorized Newspaper in such city as the
      Company shall advise the Trustee that such stock exchange so requires, on
      a Business Day at least twice, the first such publication to be not
      earlier than the earliest date and the second such publication not later
      than the latest date prescribed for the giving of such notice.

      In any case where notice to Holders of Registered Securities is given by
mail, neither the failure to mail such notice, nor any defect in any notice so
mailed, to any particular Holder of a Registered Security shall affect the
sufficiency of such notice with respect to other Holders of Registered
Securities or the sufficiency of any notice to Holders of Bearer Securities
given as provided herein. Any notice which is mailed in the manner herein
provided shall be conclusively presumed to have been duly given or provided. In
the 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


                                       16
<PAGE>

by mail, then such notification as shall be made with the approval of the
Trustee shall constitute a sufficient notification for every purpose hereunder.

      In case by reason of the suspension of publication of any Authorized
Newspaper or Authorized Newspapers or by reason of any other cause it shall be
impracticable to publish any notice to Holders of Bearers Securities as provided
above, then such notification to Holders of Bearer Securities as shall be given
with the approval of the Trustee shall constitute sufficient notice to such
Holders for every purpose hereunder. Neither failure to give notice by
publication to Holders of Bearer Securities as provided above, nor any defect in
any notice so published, shall affect the sufficiency of any notice mailed to
Holders of Registered Securities as provided above.

      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 of Securities shall be filed with the Trustee, but
such filing shall not be a condition precedent to the validity of any action
taken in reliance upon such waiver.

      Section 1.7. Language of Notices.

      Any request, demand, authorization, direction, notice, consent, election
or waiver required or permitted under this Indenture shall be in the English
language, except that, if the Company or the Guarantor, as the case may be, so
elects, any published notice may be in an official language of the country of
publication.

      Section 1.8. Conflict with Trust Indenture Act.

      If any provision hereof limits, qualifies or conflicts with any duties
under any required provision of the Trust Indenture Act imposed hereon by
Section 318(c) thereof, such required provision shall control.

      Section 1.9. Effect of Headings and Table of Contents.

      The Article and Section headings herein and the Table of Contents are for

assigns, whether so expressed or not.

      Section 1.11. Separability Clause.

      In case any provision in this Indenture, any Security or any Coupon shall

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

      Section 1.12. Benefits of Indenture.

      Nothing in this Indenture, any Security or any Coupon, express or implied,
shall give to any Person, other than the parties hereto, any Security Registrar,
any Paying Agent, any Authenticating Agent and their successors hereunder and
the Holders of Securities or Coupons, any benefit or any legal or equitable
right, remedy or claim under this Indenture.

      Section 1.13. Governing Law.

      This Indenture, the Securities and any Coupons shall be governed by and

      Unless otherwise specified in or pursuant to this Indenture or any
Securities, in any case where any Interest Payment Date, Stated Maturity or
Maturity of any Security, or the last date on which a Holder has the right to
convert or exchange Securities of a series that are convertible or exchangeable,
shall be a Legal Holiday at any Place of Payment, then (notwithstanding any
other provision of this Indenture, any Security or any Coupon other than a
provision in any Security or Coupon that specifically states that such provision
shall apply in lieu hereof) payment need not be made at such Place of Payment on
such date, and such Securities need not be converted or exchanged on such date
but such payment may be made, and such Securities may be converted or exchanged,
on the next succeeding day that is a Business Day at such Place of Payment with
the same force and effect as if made on the Interest Payment Date or at the
Stated Maturity or Maturity or on such last day for conversion or exchange, and
no interest shall accrue on the amount payable on such date or at such time for
the period from and after such Interest Payment Date, Stated Maturity, Maturity
or last day for conversion or exchange, as the case may be, to such next
succeeding Business Day.

      Section 1.15. Counterparts.

      This Indenture may be executed in several counterparts, each of which

      Section 1.16. Judgment Currency.

      The Company and the Guarantor each agrees, to the fullest extent that it
may effectively do so under applicable law, that (a) if for the purpose of
obtaining judgment in any court it is


                                       18
<PAGE>

necessary to convert the sum due in respect of the principal of, or premium or
interest, if any, or Additional Amounts on the Securities of any series (the
"Required Currency") into a currency in which a judgment will be rendered (the
"Judgment Currency"), the rate of exchange used shall be the rate at which in
accordance with normal banking procedures the Trustee could purchase in The City
of New York the requisite amount of the Required Currency with the Judgment
Currency on the New York Banking Day preceding the day on which a final
unappealable judgment is given and (b) its obligations under this Indenture to
make payments in the Required Currency (i) shall not be discharged or satisfied
by any tender, or any recovery pursuant to any judgment (whether or not entered
in accordance with clause (a)), in any currency other than the Required
Currency, except to the extent that such tender or recovery shall result in the
actual receipt, by the payee, of the full amount of the Required Currency
expressed to be payable in respect of such payments, (ii) shall be enforceable
as an alternative or additional cause of action for the purpose of recovering in
the Required Currency the amount, if any, by which such actual receipt shall
fall short of the full amount of the Required Currency so expressed to be
payable and (iii) shall not be affected by judgment being obtained for any other
sum due under this Indenture. For purposes of the foregoing, "New York Banking
Day" means any day except a Saturday, Sunday or a legal holiday in The City of
New York or a day on which banking institutions in The City of New York are
authorized or obligated by law, regulation or executive order to be closed.

hereafter enacted and in effect in any jurisdiction where property of the
Company, the Guarantor or their respective Subsidiaries is or may be located.

      Section 1.18. Limitation on Individual Liability.

      No recourse under or upon any obligation, covenant or agreement contained
in this Indenture or in any Security, or for any claim based thereon or
otherwise in respect thereof, shall be had against any incorporator, shareholder
(except in a shareholder's corporate capacity as Guarantor), officer or
director, as such, past, present or future, of the Company or the Guarantor, as
the case may be, either directly or through the Company or the Guarantor, as the

by the enforcement of any assessment or penalty or otherwise; it being expressly
understood that this Indenture and the obligations issued hereunder are solely
corporate obligations, and that no such personal liability whatever shall attach

Indenture or in any Security or implied therefrom; and that any and all such
personal liability of every name and nature, either at common law or in equity
or by constitution or statute, of, and any and all such rights and claims

acceptance, the Company or the Guarantor, as the case may be, shall notify the

each further agrees for the benefit of the Trustee and the Holders of the
Securities and the Coupons to take any and all action, including the execution

any failure by the Company or the Guarantor to take any such action. Nothing
herein shall affect the right to serve process in any other manner permitted by
any law or limit the right of the Trustee or any Holder to institute proceedings
against the Company or the Guarantor in the courts of any other jurisdiction or
jurisdictions.

            (16) if the principal of, any premium or interest on or any
      Additional Amounts with respect to any of such Securities are to be
      payable, at the election of the Company or a Holder thereof or otherwise,
      in Dollars or in a Foreign Currency other than that in which such
      Securities are stated to be payable, the date or dates on which, the
      period or periods within which, and the other terms and conditions upon
      which, such election may be made, and the time and manner of determining
      the exchange rate between the Currency in which such Securities are stated
      to be payable and the Currency in which such Securities or any of them are
      to be paid pursuant to such election, and any deletions from or
      modifications of or additions to the terms of this Indenture to provide
      for or to facilitate the issuance of Securities denominated or payable, at
      the election of the Company or a Holder thereof or otherwise, in a Foreign
      Currency;

            (17) whether the amount of payments of principal of, any premium or
      interest on or any Additional Amounts with respect to such Securities may
      be determined with reference to an index, formula or other method or
      methods (which index, formula or method or methods may be based, without
      limitation, on one or more Currencies, commodities, equity securities,
      equity indices or other indices), and, if so, the terms and conditions
      upon which and the manner in which such amounts shall be determined and
      paid or payable;

            (18) any deletions from, modifications of or additions to the Events
      of Default or covenants of the Company or the Guarantor with respect to
      any of such Securities, whether or not such Events of Default or covenants
      are consistent with the Events of Default or covenants set forth herein;

            (19) whether either or both of Section 4.2(2) relating to defeasance
      or Section 4.2(3) relating to covenant defeasance shall not be applicable
      to the Securities of such series, or any covenants in addition to those
      specified in Section 4.2(3) relating to the Securities of such series
      which shall be subject to covenant defeasance, and any deletions from, or
      modifications or additions to, the provisions of Article 4 in respect of
      the Securities of such series;

            (20) whether any of such Securities are to be issuable upon the
      exercise of warrants, and the time, manner and place for such Securities
      to be authenticated and delivered;


                                       25
<PAGE>

            (21) if any of such Securities are to be issuable in global form and
      are to be issuable in definitive form (whether upon original issue or upon
      exchange of a temporary Security) only upon receipt of certain
      certificates or other documents or satisfaction of other conditions, then
      the form and terms of such certificates, documents or conditions;

            (22) if there is more than one Trustee, the identity of the Trustee
      and, if not the Trustee, the identity of each Security Registrar, Paying
      Agent or Authenticating Agent with respect to such Securities; and

            (23) any other terms of such Securities and any other deletions from
      or modifications or additions to this Indenture in respect of such
      Securities.

      All Securities of any one series and all Coupons, if any, appertaining to
Bearer Securities of such series shall be substantially identical except as to
Currency of payments due thereunder, denomination and the rate of interest
thereon, or method of determining the rate of interest, if any, Maturity, and
the date from which interest, if any, shall accrue and except as may otherwise
be provided by the Company in or pursuant to the Board Resolution and set forth
in the Officer's Certificate or in any indenture or indentures supplemental
hereto pertaining to such series of Securities. The terms of the Securities of
any series may provide, without limitation, that the Securities shall be
authenticated and delivered by the Trustee on original issue from time to time
upon written order of persons designated in the Officer's Certificate or
supplemental indenture and that such persons are authorized to determine,
consistent with such Officer's Certificate or any applicable supplemental
indenture, such terms and conditions of the Securities of such series as are
specified in such Officer's Certificate or supplemental indenture. All
Securities of any one series need not be issued at the same time and, unless
otherwise so provided, a series may be reopened for issuances of additional
Securities of such series or to establish additional terms of such series of
Securities.

      If any of the terms of the Securities of any series shall be established
by action taken by or pursuant to a Board Resolution, the Board Resolution shall
be delivered to the Trustee at or prior to the delivery of the Officer's
Certificate setting forth the terms of such series.

      Section 3.2. Currency; Denominations.

      Unless otherwise provided in or pursuant to this Indenture, the principal
of, any premium and interest on and any Additional Amounts with respect to the
Securities shall be payable in Dollars. Unless otherwise provided in or pursuant
to this Indenture, Registered Securities denominated in Dollars shall be
issuable in registered form without Coupons in denominations of $1,000 and any
integral multiple thereof, and the Bearer Securities denominated in Dollars
shall be issuable in the denomination of $5,000. Securities not denominated in
Dollars shall be issuable in such denominations as are established with respect
to such Securities in or pursuant to this Indenture.

      Section 3.3. Execution, Authentication, Delivery and Dating. .

      Securities shall be executed on behalf of the Company by its Chairman of
the Board, a Vice Chairman, its President, its Treasurer or a Vice President
under its corporate seal reproduced thereon and attested by its Secretary or one
of its Assistant Secretaries. Coupons shall be executed on behalf of the Company
by the Treasurer or any Assistant Treasurer of the Company. The signature of any
of these officers on the Securities or any Coupons appertaining thereto may be
manual or facsimile.

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

      At any time and from time to time after the execution and delivery of this
Indenture, the Company may deliver Securities, together with any Coupons
appertaining thereto, executed by the Company, to the Trustee for authentication
and, provided that the Board Resolution and Officer's Certificate or
supplemental indenture or indentures with respect to such Securities referred to
in Section 3.1 and a Company Order for the authentication and delivery of such
Securities have been delivered to the Trustee, the Trustee in accordance with
the Company Order and subject to the provisions hereof and of such Securities
shall authenticate and deliver such Securities. In authenticating such
Securities, and accepting the additional responsibilities under this Indenture
in relation to such Securities and any Coupons appertaining thereto, the Trustee
shall be entitled to receive, and (subject to Sections 315(a) through 315(d) of
the Trust Indenture Act) shall be fully protected in relying upon,

            (1) an Opinion of Counsel to the effect that:

                  (a) the form or forms and terms of such Securities and
            Coupons, if any, have been established in conformity with the
            provisions of this Indenture;

                  (b) all conditions precedent to the authentication and
            delivery of such Securities and Coupons, if any, appertaining
            thereto, have been complied with and that such Securities and
            Coupons, when completed by appropriate insertions, executed under
            the Company's corporate seal and attested by duly authorized
            officers of the Company, delivered by duly authorized officers of
            the Company to the Trustee for authentication pursuant to this
            Indenture, and authenticated and delivered by the Trustee and issued
            by the Company in the manner and subject to any conditions specified
            in such Opinion of Counsel, will constitute legally valid and
            binding obligations of the Company, enforceable against the Company
            in accordance with their terms, except as enforcement thereof may be
            subject to or limited by bankruptcy, insolvency, reorganization,
            moratorium, arrangement, fraudulent conveyance, fraudulent transfer
            or other similar laws relating to or affecting creditors' rights
            generally, and subject to general principles of equity


                                       27
<PAGE>

            (regardless of whether enforcement is sought in a proceeding in
            equity or at law) and will entitle the Holders thereof to the
            benefits of this Indenture, including the Guarantee; such Opinion of
            Counsel need express no opinion as to the availability of equitable
            remedies;

                  (c) all laws and requirements in respect of the execution and
            delivery by the Company of such Securities and Coupons, if any, have
            been complied with; and

                  (d) this Indenture has been qualified under the Trust
            Indenture Act; and

            (2) an Officer's Certificate and a Guarantor's Officer's
      Certificate, in each case stating that, to the best knowledge of the
      Persons executing such certificate, all conditions precedent to the
      execution, authentication and delivery of such Securities and Coupons, if
      any, appertaining thereto, have been complied with, and no event which is,
      or after notice or lapse of time would become, an Event of Default with
      respect to any of the Securities shall have occurred and be continuing.

      If all the Securities of any series are not to be issued at one time, it
shall not be necessary to deliver an Opinion of Counsel and an Officer's
Certificate and Guarantor's Officer's Certificate at the time of issuance of
each Security, but such opinion and certificates, with appropriate
modifications, shall be delivered at or before the time of issuance of the first
Security of such series. After any such first delivery, any separate written
request by an Authorized Officer of the Company or any person designated in
writing by an Authorized Officer that the Trustee authenticate and deliver
Securities of such series for original issue will be deemed to be a
certification by the Company and the Guarantor that all conditions precedent
provided for in this Indenture relating to authentication and delivery of such
Securities continue to have been complied with and that no Event of Default with
respect to any of the Securities has occurred or is continuing.

      The Trustee shall not be required to authenticate or to cause an
Authenticating Agent to authenticate any Securities if the issue of such
Securities pursuant to this Indenture will affect the Trustee's own rights,
duties or immunities under the Securities and this Indenture or otherwise in a
manner which is not reasonably acceptable to the Trustee or if the Trustee,
being advised by counsel, determines that such action may not lawfully be taken.

      Each Registered Security shall be dated the date of its authentication.
Each Bearer Security and any Bearer Security in global form shall be dated as of
the date specified in or pursuant to this Indenture.

      No Security or Coupon appertaining thereto shall be entitled to any
benefit under this Indenture or be valid or obligatory for any purpose, unless
there appears on such Security a certificate of authentication substantially in
the form provided for in Section 2.2 or 6.11 executed by or on behalf of the
Trustee or by the Authenticating Agent by the manual signature of one of


                                       28
<PAGE>

its authorized officers. Such certificate upon any Security shall be conclusive
evidence, and the only evidence, that such Security has been duly authenticated
and delivered hereunder. Except as permitted by Section 3.6 or 3.7, the Trustee
shall not authenticate and deliver any Bearer Security unless all Coupons
appertaining thereto then matured have been detached and cancelled.

      Section 3.4. Temporary Securities.

      Pending the preparation of definitive Securities, the Company may execute
and deliver to the Trustee and, upon Company Order, the Trustee shall
authenticate and deliver, in the manner provided in Section 3.3, temporary
Securities in lieu thereof which are printed, lithographed, typewritten,
mimeographed or otherwise produced, in any authorized denomination,
substantially of the tenor of the definitive Securities in lieu of which they
are issued, in registered form or, if authorized in or pursuant to this
Indenture, in bearer form with one or more Coupons or without Coupons and with
such appropriate insertions, omissions, substitutions and other variations as
the officers of the Company executing such Securities may determine, as
conclusively evidenced by their execution of such Securities. Such temporary
Securities may be in global form.

      Except in the case of temporary Securities in global form, which shall be
exchanged in accordance with the provisions thereof, if temporary Securities are
issued, the Company shall cause definitive Securities to be prepared without
unreasonable delay. After the preparation of definitive Securities of the same
series and containing terms and provisions that are identical to those of any
temporary Securities, such temporary Securities shall be exchangeable for such
definitive Securities upon surrender of such temporary Securities at an Office
or Agency for such Securities, without charge to any Holder thereof. Upon
surrender for cancellation of any one or more temporary Securities (accompanied
by any unmatured Coupons appertaining thereto), the Company shall execute and
the Trustee shall authenticate and deliver in exchange therefor a like principal
amount of definitive Securities of authorized denominations of the same series
and containing identical terms and provisions; provided, however, that no
definitive Bearer Security, except as provided in or pursuant to this Indenture,
shall be delivered in exchange for a temporary Registered Security; and
provided, further, that a definitive Bearer Security shall be delivered in
exchange for a temporary Bearer Security only in compliance with the conditions
set forth in or pursuant to this Indenture. Unless otherwise provided in or
pursuant to this Indenture with respect to a temporary global Security, until so
exchanged the temporary Securities of any series shall in all respects be
entitled to the same benefits under this Indenture as definitive Securities of
such series.

      Section 3.5. Registration, Transfer and Exchange.

      With respect to the Registered Securities of each series, if any, the
Company shall cause to be kept a register (each such register being herein
sometimes referred to as the "Security Register") at an Office or Agency for
such series in which, subject to such reasonable regulations as it may
prescribe, the Company shall provide for the registration of the Registered
Securities of such series and of transfers of the Registered Securities of such
series. Such Office or Agency shall be the "Security Registrar" for that series
of Securities. Unless otherwise specified in or pursuant to this Indenture or
the Securities, the Trustee shall be the initial Security Registrar for


                                       29
<PAGE>

each series of Securities. The Company shall have the right to remove and
replace from time to time the Security Registrar for any series of Securities;
provided that no such removal or replacement shall be effective until a
successor Security Registrar with respect to such series of Securities shall
have been appointed by the Company and shall have accepted such appointment by
the Company. In the event that the Trustee shall not be or shall cease to be
Security Registrar with respect to a series of Securities, it shall have the
right to examine the Security Register for such series at all reasonable times.
There shall be only one Security Register for each series of Securities.

      Upon surrender for registration of transfer of any Registered Security of
any series at any Office or Agency for such series, the Company shall execute,
and the Trustee shall authenticate and deliver, in the name of the designated
transferee or transferees, one or more new Registered Securities of the same
series denominated as authorized in or pursuant to this Indenture, of a like
aggregate principal amount bearing a number not contemporaneously outstanding
and containing identical terms and provisions.

      At the option of the Holder, Registered Securities of any series may be
exchanged for other Registered Securities of the same series containing
identical terms and provisions, in any authorized denominations, and of a like
aggregate principal amount, upon surrender of the Securities to be exchanged at
any Office or Agency for such series. Whenever any Registered Securities are so
surrendered for exchange, the Company shall execute, and the Trustee shall
authenticate and deliver, the Registered Securities which the Holder making the
exchange is entitled to receive.

      If provided in or pursuant to this Indenture, with respect to Securities
of any series, at the option of the Holder, Bearer Securities of such series may
be exchanged for Registered Securities of such series containing identical
terms, denominated as authorized in or pursuant to this Indenture and in the
same aggregate principal amount, upon surrender of the Bearer Securities to be
exchanged at any Office or Agency for such series, with all unmatured Coupons
and all matured Coupons in default thereto appertaining. If the Holder of a
Bearer Security is unable to produce any such unmatured Coupon or Coupons or
matured Coupon or Coupons in default, such exchange may be effected if the
Bearer Securities are accompanied by payment in funds acceptable to the Company,
the Guarantor and the Trustee in an amount equal to the face amount of such
missing Coupon or Coupons, or the surrender of such missing Coupon or Coupons
may be waived by the Company, the Guarantor and the Trustee if there is
furnished to them such security or indemnity as they may require to save each of
them and any Paying Agent harmless. If thereafter the Holder of such Bearer
Security shall surrender to any Paying Agent any such missing Coupon in respect
of which such a payment shall have been made, such Holder shall be entitled to
receive the amount of such payment; provided, however, that, except as otherwise
provided in Section 10.2, interest represented by Coupons shall be payable only
upon presentation and surrender of those Coupons at an Office or Agency for such
series located outside the United States. Notwithstanding the foregoing, in case
a Bearer Security of any series is surrendered at any such Office or Agency for
such series in exchange for a Registered Security of such series and like tenor
after the close of business at such Office or Agency on (i) any


                                       30
<PAGE>

Regular Record Date and before the opening of business at such Office or Agency
on the next succeeding Interest Payment Date, or (ii) any Special Record Date
and before the opening of business at such Office or Agency on the related date
for payment of Defaulted Interest, such Bearer Security shall be surrendered
without the Coupon relating to such Interest Payment Date or proposed date of
payment, as the case may be (or, if such Coupon is so surrendered with such
Bearer Security, such Coupon shall be returned to the Person so surrendering the
Bearer Security), and interest or Defaulted Interest, as the case may be, shall
not be payable on such Interest Payment Date or proposed date for payment, as
the case may be, in respect of the Registered Security issued in exchange for
such Bearer Security, but shall be payable only to the Holder of such Coupon
when due in accordance with the provisions of this Indenture.

      If provided in or pursuant to this Indenture with respect to Securities of
any series, at the option of the Holder, Registered Securities of such series
may be exchanged for Bearer Securities upon such terms and conditions as may be
provided in or pursuant to this Indenture with respect to such series.

      Whenever any Securities are surrendered for exchange as contemplated by
the immediately preceding two paragraphs, the Company shall execute, and the
Trustee shall authenticate and deliver, the Securities which the Holder making
the exchange is entitled to receive.

      Notwithstanding the foregoing, except as otherwise provided in or pursuant
to this Indenture, any global Security shall be exchangeable for definitive
Securities only if (i) the Depository is at any time unwilling, unable or
ineligible to continue as depository and a successor depository is not appointed
by the Company within 90 days of the date the Company is so informed in writing,
(ii) the Company executes and delivers to the Trustee a Company Order to the
effect that such global Security shall be so exchangeable, or (iii) an Event of
Default has occurred and is continuing with respect to the Securities. If the
beneficial owners of interests in a global Security are entitled to exchange
such interests for definitive Securities as the result of an event described in
clause (i), (ii) or (iii) of the preceding sentence, then without unnecessary
delay but in any event not later than the earliest date on which such interests
may be so exchanged, the Company shall deliver to the Trustee definitive
Securities in such form and denominations as are required by or pursuant to this
Indenture, and of the same series, containing identical terms and in aggregate
principal amount equal to the principal amount of such global Security, executed
by the Company. On or after the earliest date on which such interests may be so
exchanged, such global Security shall be surrendered from time to time by the
U.S. Depository or such other Depository as shall be specified in the Company
Order with respect thereto, and in accordance with instructions given to the
Trustee and the U.S. Depository or such other Depository, as the case may be
(which instructions shall be in writing but need not be contained in or
accompanied by an Officer's Certificate or be accompanied by an Opinion of
Counsel), as shall be specified in the Company Order with respect thereto to the
Trustee, as the Company's agent for such purpose, to be exchanged, in whole or
in part, for definitive Securities as described above without charge. The
Trustee shall authenticate and make available for delivery, in exchange for each
portion of such surrendered global Security, a like aggregate


                                       31
<PAGE>

principal amount of definitive Securities of the same series of authorized
denominations and of like tenor as the portion of such global Security to be
exchanged, which (unless such Securities are not issuable both as Bearer
Securities and as Registered Securities, in which case the definitive Securities
exchanged for the global Security shall be issuable only in the form in which
the Securities are issuable, as provided in or pursuant to this Indenture) shall
be in the form of Bearer Securities or Registered Securities, or any combination
thereof, as shall be specified by the beneficial owner thereof, but subject to
the satisfaction of any certification or other requirements to the issuance of
Bearer Securities; provided, however, that no such exchanges may occur during a
period beginning at the opening of business 15 days before any selection of
Securities of the same series to be redeemed and ending on the relevant
Redemption Date; and provided, further, that (unless otherwise provided in or
pursuant to this Indenture) no Bearer Security delivered in exchange for a
portion of a global Security shall be mailed or otherwise delivered to any
location in the United States. Promptly following any such exchange in part,
such global Security shall be returned by the Trustee to such Depository or the
U.S. Depository, as the case may be, or such other Depository or U.S. Depository
referred to above in accordance with the instructions of the Company referred to
above. If a Registered Security is issued in exchange for any portion of a
global Security after the close of business at the Office or Agency for such
Security where such exchange occurs on or after (i) any Regular Record Date for
such Security and before the opening of business at such Office or Agency on the
next succeeding Interest Payment Date, or (ii) any Special Record Date for such
Security and before the opening of business at such Office or Agency on the
related proposed date for payment of interest or Defaulted Interest, as the case
may be, interest shall not be payable on such Interest Payment Date or proposed
date for payment, as the case may be, in respect of such Registered Security,
but shall be payable on such Interest Payment Date or proposed date for payment,
as the case may be, only to the Person to whom interest in respect of such
portion of such global Security shall be payable in accordance with the
provisions of this Indenture.

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

      Every Registered Security presented or surrendered for registration of
transfer or for exchange or redemption shall (if so required by the Company or
the Security Registrar for such Security) be duly endorsed, or be accompanied by
a written instrument of transfer in form satisfactory to the Company and the
Security Registrar for such Security 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, or redemption of Securities, but the Company may require payment of a
sum sufficient to cover any tax or other governmental charge and any other
expenses (including fees and expenses of the Trustee) that may be imposed in
connection with any registration of transfer or exchange of Securities, other
than exchanges pursuant to Section 3.4, 9.5 or 11.7 not involving any transfer.


                                       32
<PAGE>

      Except as otherwise provided in or pursuant to this Indenture, the Company
shall not be required (i) to issue, register the transfer of or exchange any
Securities during a period beginning at the opening of business 15 days before
the day of mailing of a notice of redemption of Securities of like tenor and the
same series under Section 11.3 and ending at the close of business on the day of
such mailing, or (ii) to register the transfer of or exchange any Registered
Security selected for redemption in whole or in part, except in the case of any
Security to be redeemed in part, the portion thereof not to be redeemed, or
(iii) to exchange any Bearer Security selected for redemption except, to the
extent provided with respect to such Bearer Security, that such Bearer Security
may be exchanged for a Registered Security of like tenor and the same series,
provided that such Registered Security shall be immediately surrendered for
redemption with written instruction for payment consistent with the provisions
of this Indenture or (iv) to issue, register the transfer of or exchange any
Security which, in accordance with its terms, has been surrendered for repayment
at the option of the Holder, except the portion, if any, of such Security not to
be so repaid.

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

      If any mutilated Security or a Security with a mutilated Coupon
appertaining to it is surrendered to the Trustee, subject to the provisions of
this Section 3.6, the Company shall execute and the Trustee shall authenticate
and deliver in exchange therefor a new Security of the same series containing
identical terms and of like principal amount and bearing a number not
contemporaneously outstanding, with Coupons appertaining thereto corresponding
to the Coupons, if any, appertaining to the surrendered Security.

      If there be delivered to the Company, the Guarantor and the Trustee (i)
evidence to their satisfaction of the destruction, loss or theft of any Security
or Coupon, and (ii) such security 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, the Guarantor or the Trustee that such Security or
Coupon has been acquired by a bona fide purchaser, the Company shall execute
and, upon the Company's request the Trustee shall authenticate and deliver, in
exchange for or in lieu of any such mutilated, destroyed, lost or stolen
Security or in exchange for the Security to which a destroyed, lost or stolen
Coupon appertains with all appurtenant Coupons not destroyed, lost or stolen, a
new Security of the same series containing identical terms and of like principal
amount and bearing a number not contemporaneously outstanding, with Coupons
appertaining thereto corresponding to the Coupons, if any, appertaining to such
destroyed, lost or stolen Security or to the Security to which such destroyed,
lost or stolen Coupon appertains.

      Notwithstanding the foregoing provisions of this Section 3.6, in case any
mutilated, destroyed, lost or stolen Security or Coupon has become or is about
to become due and payable, the Company in its discretion may, instead of issuing
a new Security, pay such Security or Coupon; provided, however, that payment of
principal of, any premium or interest on or any Additional Amounts with respect
to any Bearer Securities shall, except as otherwise provided in Section 10.2, be
payable only at an Office or Agency for such Securities located outside the
United States and, unless otherwise provided in or pursuant to this Indenture,
any interest on


                                       33
<PAGE>

Bearer Securities and any Additional Amounts with respect to such interest shall
be payable only upon presentation and surrender of the Coupons appertaining
thereto.

      Upon the issuance of any new Security under this Section 3.6, the Company
may require the payment of a sum sufficient to cover any tax or other
governmental charge that may be imposed in relation thereto and any other
expenses (including the fees and expenses of the Trustee) connected therewith.

      Every new Security, with any Coupons appertaining thereto issued pursuant
to this Section 3.6 in lieu of any destroyed, lost or stolen Security, or in
exchange for a Security to which a destroyed, lost or stolen Coupon appertains
shall constitute a separate obligation of the Company and the Guarantor, whether
or not the destroyed, lost or stolen Security and Coupons appertaining thereto
or the destroyed, lost or stolen Coupon shall be at any time enforceable by
anyone, and shall be entitled to all the benefits of this Indenture equally and
proportionately with any and all other Securities of such series and any
Coupons, if any, duly issued hereunder.

      The provisions of this Section 3.6, as amended or supplemented pursuant to
this Indenture with respect to particular Securities or generally, shall be
exclusive and shall preclude (to the extent lawful) all other rights and
remedies with respect to the replacement or payment of mutilated, destroyed,
lost or stolen Securities or Coupons.

      Section 3.7. Payment of Interest and Certain Additional Amounts; Rights to
Interest and Certain Additional Amounts Preserved.

      Unless otherwise provided in or pursuant to this Indenture, any interest
on and any Additional Amounts with respect to any Registered Security which
shall be payable, and are punctually paid or duly provided for, on any Interest
Payment Date shall be paid to the Person in whose name such Security (or one or
more Predecessor Securities) is registered as of the close of business on the
Regular Record Date for such interest.

      Unless otherwise provided in or pursuant to this Indenture, any interest
on and any Additional Amounts with respect to any Registered Security which
shall be payable, but shall not be punctually paid or duly provided for, on any
Interest Payment Date for such Registered Security (herein called "Defaulted
Interest") shall forthwith cease to be payable to the Holder thereof on the
relevant Regular Record Date by virtue of having been such Holder; and such
Defaulted Interest may be paid by the Company or the Guarantor, at its election
in each case, as provided in Clause (1) or (2) below:

            (1) The Company or the Guarantor, as the case may be, may elect to
      make payment of any Defaulted Interest to the Person in whose name such
      Registered Security (or a Predecessor Security thereof) shall be
      registered at the close of business on a Special Record Date for the
      payment of such Defaulted Interest, which shall be fixed by the Company in
      the following manner. The Company or the Guarantor, as the case may be,
      shall notify the Trustee in writing of the amount of Defaulted Interest
      proposed to be paid on such Registered Security, the Special Record Date
      therefor and the date of the


                                       34
<PAGE>

      proposed payment, and at the same time the Company or the Guarantor, as
      the case may be, shall deposit with the Trustee an amount of money equal
      to the aggregate amount proposed to be paid in respect of such Defaulted
      Interest or shall make arrangements satisfactory to the Trustee for such
      deposit on or prior to the date of the proposed payment, such money when
      so deposited to be held in trust for the benefit of the Person entitled to
      such Defaulted Interest as in this Clause provided. The Special Record
      Date for the payment of such Defaulted Interest 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 notification to the Trustee of the
      proposed payment. The Trustee shall, in the name and at the expense of the
      Company or the Guarantor, cause notice of the proposed payment of such
      Defaulted Interest and the Special Record Date therefor to be mailed,
      first-class postage prepaid, to the Holder of such Registered Security (or
      a Predecessor Security thereof) at his address as it appears in the
      Security Register not less than 10 days prior to such Special Record Date.
      The Trustee may, in its discretion, in the name and at the expense of the
      Company or the Guarantor, cause a similar notice to be published at least
      once in an Authorized Newspaper of general circulation in the Borough of
      Manhattan, The City of New York, but such publication shall not be a
      condition precedent to the establishment of such Special Record Date.
      Notice of the proposed payment of such Defaulted Interest and the Special
      Record Date therefor having been mailed as aforesaid, such Defaulted
      Interest shall be paid to the Person in whose name such Registered
      Security (or a Predecessor Security thereof) shall be registered at the
      close of business on such Special Record Date and shall no longer be
      payable pursuant to the following clause (2).

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

      Unless otherwise provided in or pursuant to this Indenture or the
Securities of any particular series pursuant to the provisions of this
Indenture, at the option of the Company or the Guarantor, interest on Registered
Securities that bear interest may be paid by mailing a check to the address of
the Person entitled thereto as such address shall appear in the Security
Register or by transfer to an account maintained by the payee with a bank
located in the United States.

      Subject to the foregoing provisions of this Section and Section 3.5, each
Security delivered under this Indenture upon registration of transfer of or in
exchange for or in lieu of any other Security shall carry the rights to interest
accrued and unpaid, and to accrue, which were carried by such other Security.

      In the case of any Registered Security of any series that is convertible
into other securities of the Company or exchangeable for securities of the
Guarantor or another issuer,


                                       35

which Registered Security is converted or exchanged after any Regular Record
Date and on or prior to the next succeeding Interest Payment Date (other than
any Registered Security with respect to which the Stated Maturity is prior to
such Interest Payment Date), interest with respect to which the Stated Maturity
is on such Interest Payment Date shall be payable on such Interest Payment Date
notwithstanding such conversion or exchange, and such interest (whether or not
punctually paid or duly provided for) shall be paid to the Person in whose name
that Registered Security (or one or more predecessor Registered Securities) is
registered at the close of business on such Regular Record Date. Except as
otherwise expressly provided in the immediately preceding sentence, in the case
of any Registered Security which is converted or exchanged, interest with
respect to which the Stated Maturity is after the date of conversion or exchange
of such Registered Security shall not be payable.

      Section 3.8. Persons Deemed Owners.

      Prior to due presentment of a Registered Security for registration of
transfer, the Company, the Guarantor, the Trustee and any agent of the Company
or the Guarantor or the Trustee may treat the Person in whose name such

Registered Security for the purpose of receiving payment of principal of, any
premium and (subject to Sections 3.5 and 3.7) interest on and any Additional
Amounts with respect to such Registered Security and for all other purposes
whatsoever, whether or not any payment with respect to such Registered Security

agent of the Company, the Guarantor or the Trustee shall be affected by notice
to the contrary.

Coupon shall be overdue, and none of the Company, the Guarantor, the Trustee or
any agent of the Company, the Guarantor or the Trustee shall be affected by
notice to the contrary.

behalf by a Depository shall have any rights under this Indenture with respect
to such global Security, and such Depository may be treated by the Company, the
Guarantor, the Trustee, and any agent of the Company, the Guarantor or the
Trustee as the owner of such global Security for all purposes whatsoever. None
of the Company, the Guarantor, the Trustee, any Paying Agent or the Security
Registrar will have any responsibility or liability for any aspect of the
records relating to or payments made on account of beneficial ownership
interests of a global Security or for maintaining, supervising or reviewing any

return to it.

      4.2 shall not be applicable with respect to the Securities of such series
      or (ii) covenant defeasance of the Securities of or within a series under
      clause (3) of this Section 4.2 shall not be applicable with respect to the
      Securities of such series, then such provisions, together with the other
      provisions of this Section 4.2 (with such modifications thereto as may be
      specified pursuant to Section 3.1 with respect to any Securities), shall

      the Company may at its option by Board Resolution, at any time, with
      respect to such Securities and any Coupons appertaining thereto, elect to
      have Section 4.2(2) or Section 4.2(3) be applied to such Outstanding
      Securities and any Coupons appertaining thereto upon compliance with the
      conditions set forth below in this Section 4.2.

            (2) Upon the Company's exercise of the above option applicable to
      this Section 4.2(2) with respect to any Securities of or within a series,
      the Company and the Guarantor shall be deemed to have been discharged from
      its obligations with respect to such Outstanding Securities and any
      Coupons appertaining thereto and under the Guarantee in respect thereof,
      respectively, on the date the conditions set forth in clause (4) of this
      Section 4.2 are satisfied (hereinafter, "defeasance"). For this purpose,
      such defeasance means that the Company or the Guarantor shall be deemed to
      have paid and discharged the entire Indebtedness represented by such
      Outstanding Securities and any Coupons appertaining thereto, and under the
      Guarantee in respect thereof, which shall thereafter be deemed to be
      "Outstanding" only for the purposes of clause (5) of this Section 4.2 and
      the other Sections of this Indenture referred to in clauses (i) and (ii)
      below, and to have satisfied all of its other obligations under such
      Securities and any Coupons appertaining thereto, and under the Guarantee
      in respect thereof, and this Indenture insofar as such Securities and any
      Coupons appertaining thereto, and the Guarantee in respect thereof, are
      concerned (and the Trustee, at the expense of the Company and the
      Guarantor, shall execute proper instruments acknowledging the same),
      except for the following which shall survive until otherwise terminated or
      discharged hereunder: (i) the rights of Holders of such Outstanding
      Securities and any Coupons appertaining thereto to receive, solely from
      the trust fund described in clause (4) of this Section 4.2 and as more
      fully set forth in such clause, payments in respect of the principal of

      Securities for securities of the Guarantor or another issuer, (ii) the
      obligations of the Company, the Guarantor and the Trustee with respect to
      such Securities under Sections 3.5, 3.6, 10.2 and 10.3 and with respect to
      the payment of Additional Amounts, if any, on such Securities as
      contemplated by Sections 10.4 and 16.2 (but only to the extent that the
      Additional Amounts payable with respect to such Securities exceed the
      amount deposited in respect of such Additional Amounts pursuant


                                       39
<PAGE>

      to Section 4.2(4)(a) below), and with respect to any rights to convert
      such Securities into other securities of the Company or exchange such
      Securities for securities of the Guarantor or another issuer, (iii) the
      rights, powers, trusts, duties and immunities of the Trustee hereunder and
      (iv) this Section 4.2. The Company may exercise its option under this
      Section 4.2(2) notwithstanding the prior exercise of its option under
      clause (3) of this Section 4.2 with respect to such Securities and any
      Coupons appertaining thereto.

            (3) Upon the Company's exercise of the option to have this Section
      4.2(3) apply with respect to any Securities of or within a series, the
      Company and the Guarantor shall be released from their obligations under
      Sections 10.5 and 10.6, and, to the extent specified pursuant to Section
      3.1(19), any other covenant applicable to such Securities, with respect to
      such Outstanding Securities and any Coupons appertaining thereto, and the
      Guarantee in respect thereof, on and after the date the conditions set
      forth in clause (4) of this Section 4.2 are satisfied (hereinafter,
      "covenant defeasance"), and such Securities and any Coupons appertaining
      thereto shall thereafter be deemed to be not "Outstanding" for the
      purposes of any direction, waiver, consent or declaration or Act of
      Holders (and the consequences of any thereof) in connection with any such
      covenant, but shall continue to be deemed "Outstanding" for all other
      purposes hereunder. For this purpose, such covenant defeasance means that,
      with respect to such Outstanding Securities and any Coupons appertaining
      thereto, the Company and the Guarantor may omit to comply with, and shall
      have no liability in respect of, any term, condition or limitation set
      forth in any such Section or such other covenant, whether directly or
      indirectly, by reason of any reference elsewhere herein to any such
      Section or such other covenant or by reason of reference in any such
      Section or such other covenant to any other provision herein or in any
      other document and such omission to comply shall not constitute a default
      or an Event of Default under Section 5.1(4) or 5.1(9) or otherwise, as the
      case may be, but, except as specified above, the remainder of this
      Indenture and such Securities and Coupons appertaining thereto and the
      Guarantee in respect thereof shall be unaffected thereby.

      a series and any Coupons appertaining thereto and the Guarantee in respect
      thereof:

                  (a) The Company or the Guarantor shall irrevocably have

            payments, specifically pledged as security for, and dedicated solely

            as payable at Stated Maturity) which through the scheduled payment
            of principal and interest in respect thereof in accordance with
            their terms will provide, not later than one day before the due date
            of any payment of principal of (and premium, if any) and interest,
            if any, on such Securities and any Coupons appertaining thereto,
            money in an amount, or (3) a combination thereof, in any case, in an
            amount, sufficient, without consideration of any reinvestment of
            such principal and interest, in the opinion of a nationally
            recognized firm of independent public accountants expressed in a
            written certification thereof delivered to the Trustee, to pay and
            discharge, and which shall be applied by the Trustee (or other
            qualifying trustee) to pay and discharge, (y) the principal of (and
            premium, if any) and interest, if any, on such Outstanding

            Securities and any Coupons appertaining thereto.

                  (b) Such defeasance or covenant defeasance shall not result in
            a breach or violation of, or constitute a default under, this
            Indenture or any other material agreement or instrument to which the
            Company or the Guarantor is a party or by which either of them is
            bound.

                  (c) No Event of Default or event which with notice or lapse of
            time or both would become an Event of Default with respect to such
            Securities and any Coupons appertaining thereto shall have occurred
            and be continuing on the date of such deposit and, with respect to
            defeasance only, at any time during the period ending on the 123rd
            day after the date of such deposit (it being understood that this
            condition shall not be deemed satisfied until the expiration of such
            period).

                  (d) In the case of an election under clause (2) of this
            Section 4.2, the Company or the Guarantor shall have delivered to
            the Trustee an Opinion of Counsel stating that (i) the Company or
            the Guarantor has received from the Internal Revenue Service a
            letter ruling, or there has been published by the Internal Revenue
            Service a Revenue Ruling, or (ii) since the date of execution of
            this Indenture, there has been a change in the applicable Federal

            Securities and any Coupons appertaining thereto will not recognize
            income, gain or loss for Federal income tax purposes as a result of
            such defeasance and will be subject to Federal income tax on the
            same amounts, in the same manner and at the same times as would have

            purposes as a result of such covenant defeasance and will be subject
            to Federal income tax on the same amounts, in the same manner and at
            the same times as would have been the case if such covenant
            defeasance had not occurred.

            (or other property as may be provided pursuant to Section 3.1)
            (including the proceeds thereof) deposited or caused to be deposited
            with the Trustee (or other qualifying trustee) pursuant to this
            clause (4) to be held in trust will not be subject to any case or
            proceeding (whether voluntary or involuntary) in respect of the

            precedent to the defeasance or covenant defeasance under clause (2)
            or (3) of this Section 4.2 (as the case may be) have been complied
            with.

            (5) Unless otherwise specified in or pursuant to this Indenture or
      any Security, if, after a deposit referred to in Section 4.2(4)(a) has
      been made, (a) the Holder of a Security in respect of which such deposit
      was made is entitled to, and does, elect pursuant to Section 3.1 or the
      terms of such Security to receive payment in a Currency other than that in
      which the deposit pursuant to Section 4.2(4)(a) has been made in respect
      of such Security, or (b) a Conversion Event occurs in respect of the
      Foreign Currency in which the deposit pursuant to Section 4.2(4)(a) has
      been made, the indebtedness represented by such Security and any Coupons
      appertaining thereto shall be deemed to have been, and will be, fully
      discharged and satisfied through the payment of the principal of (and
      premium, if any), and interest, if any, on, and Additional Amounts, if
      any, with respect to, such Security as the same becomes due out of the
      proceeds yielded by converting (from time to time as specified below in
      the case of any such election) the amount or other property deposited in
      respect of such Security into the Currency in which such


                                       42
<PAGE>

      Security becomes payable as a result of such election or Conversion Event
      based on (x) in the case of payments made pursuant to clause (a) above,
      the applicable market exchange rate for such Currency in effect on the
      second Business Day prior to each payment date, or (y) with respect to a
      Conversion Event, the applicable market exchange rate for such Foreign
      Currency in effect (as nearly as feasible) at the time of the Conversion
      Event.

      The Company and the Guarantor (without duplication) shall pay and
indemnify the Trustee (or other qualifying trustee, collectively for purposes of
this Section 4.2(5) and Section 4.3, the "Trustee") against any tax, fee or
other charge, imposed on or assessed against the Government Obligations
deposited pursuant to this Section 4.2 or the principal or interest received in
respect thereof other than any such tax, fee or other charge which by law is for
the account of the Holders of such Outstanding Securities and any Coupons
appertaining thereto.

      Anything in this Section 4.2 to the contrary notwithstanding, the Trustee
shall deliver or pay to the Company from time to time upon Company Request, or
the Guarantor upon Guarantor Request, as the case may be, any money or
Government Obligations (or other property and any proceeds therefrom) held by it
as provided in clause (4) of this Section 4.2 which, in the opinion of a
nationally recognized firm of independent public accountants expressed in a
written certification thereof delivered to the Trustee, are in excess of the
amount thereof which would then be required to be deposited to effect a
defeasance or covenant defeasance, as applicable, in accordance with this
Section 4.2.

      Section 4.3. Application of Trust Money.

      Subject to the provisions of the last paragraph of Section 10.3, all money
and Government Obligations (or other property as may be provided pursuant to
Section 3.1) (including the proceeds thereof) deposited with the Trustee
pursuant to Section 4.1 or 4.2 in respect of any Outstanding Securities of any
series and any Coupons appertaining thereto shall be held in trust and applied
by the Trustee, in accordance with the provisions of such Securities and any
Coupons appertaining thereto and this Indenture, to the payment, either directly
or through any Paying Agent (including the Company acting as its own Paying
Agent or the Guarantor acting as Paying Agent) as the Trustee may determine, to
the Holders of such Securities and any Coupons appertaining thereto of all sums
due and to become due thereon in respect of principal (and premium, if any) and
interest and Additional Amounts, if any; but such money and Government
Obligations need not be segregated from other funds except to the extent
required by law.

      Section 5.2. Acceleration of Maturity; Rescission and Annulment.

      If an Event of Default with respect to Securities of any series at the
time Outstanding (other than an Event of Default specified in clause (7) or (8)
of Section 5.1) occurs and is continuing, then the Trustee or the Holders of not
less than 25% in principal amount of the Outstanding Securities of such series
may declare the principal of all the Securities of such series, or such lesser
amount as may be provided for in the Securities of such series, to be due and
payable immediately, by a notice in writing to the Company and the Guarantor
(and to the Trustee if given by the Holders), and upon any such declaration such
principal or such lesser amount shall become immediately due and payable.

      If an Event of Default specified in clause (7) or (8) of Section 5.1
occurs, all unpaid principal of and accrued interest on the Outstanding
Securities of that series (or such lesser amount as may be provided for in the
Securities of such series) shall ipso facto become and be immediately due and
payable without any declaration or other act on the part of the Trustee or any
Holder of any Security of that series.

      At any time after a declaration of acceleration with respect to the
Securities of any series has been made and before a judgment or decree for
payment of the money due has been obtained by the Trustee as hereinafter in this
Article provided, the Holders of not less than a majority in principal amount of
the Outstanding Securities of such series, by written notice to the Company, the
Guarantor and the Trustee, may rescind and annul such declaration and its
consequences if

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

                  (a) all overdue installments of any interest on and Additional
            Amounts with respect to all Securities of such series and any Coupon
            appertaining thereto,

                  (b) the principal of and any premium on any Securities of such
            series which have become due otherwise than by such declaration of
            acceleration and interest thereon and any Additional Amounts with
            respect thereto at the rate or rates borne by or provided for in
            such Securities,


                                       46
<PAGE>

                  (c) to the extent that payment of such interest or Additional
            Amounts is lawful, interest upon overdue installments of any
            interest and Additional Amounts at the rate or rates borne by or
            provided for in such Securities, and

                  (d) all sums paid or advanced by the Trustee hereunder and the
            reasonable compensation, expenses, disbursements and advances of the
            Trustee, its agents and counsel and all other amounts due the
            Trustee under Section 6.6; and

            (2) all Events of Default with respect to Securities of such series,
      other than the non-payment of the principal of, any premium and interest
      on, and any Additional Amounts with respect to Securities of such series
      which shall have become due solely by such declaration of acceleration,
      shall have been cured or waived as provided in Section 5.13.

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

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

      The Company and the Guarantor each covenants, in each case, that if

            (1) default is made in the payment of any installment of interest on
      or any Additional Amounts with respect to any Security or any Coupon
      appertaining thereto when such interest or Additional Amounts shall have
      become due and payable and such default continues for a period of 30 days,
      or

            (2) default is made in the payment of the principal of or any
      premium on any Security or any Additional Amounts with respect thereto at
      their Maturity,

the Company or the Guarantor, as the case may be, shall, upon demand of the
Trustee, pay to the Trustee, for the benefit of the Holders of such Securities
and any Coupons appertaining thereto, the whole amount of money then due and
payable with respect to such Securities and any Coupons appertaining thereto,
with interest upon the overdue principal, any premium and, to the extent that
payment of such interest shall be legally enforceable, upon any overdue
installments of interest and Additional Amounts at the rate or rates borne by or
provided for in such Securities, and, in addition thereto, such further amount
of money 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 and all other amounts due to the Trustee
under Section 6.6.

      If the Company or the Guarantor fails to pay the money it is required to
pay the Trustee pursuant to the preceding paragraph forthwith upon the demand of
the Trustee, the Trustee, in its own name and as trustee of an express trust,
may institute a judicial proceeding for the collection of the money so due and
unpaid, and may prosecute such proceeding to judgment or final decree,


                                       47
<PAGE>

and may enforce the same against the Company or the Guarantor or any other
obligor upon such Securities and any Coupons appertaining thereto and collect
the monies adjudged or decreed to be payable in the manner provided by law out
of the property of the Company or the Guarantor or any other obligor upon such
Securities and any Coupons appertaining thereto, wherever situated.

      If an Event of Default with respect to Securities of any series occurs and
is continuing, the Trustee may in its discretion proceed to protect and enforce
its rights and the rights of the Holders of Securities of such series and any
Coupons appertaining thereto 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 such Securities or in aid of the exercise of any power granted
herein or therein, or to enforce any other proper remedy.

      Section 5.4. Trustee May File Proofs of Claim.

bankruptcy, reorganization, arrangement, adjustment, composition or other
judicial proceeding relative to the Company, the Guarantor or any other obligor
upon the Securities of any series or the property of the Company, the Guarantor
or such other obligor or their creditors, the Trustee (irrespective of whether
the principal of the Securities shall then be due and payable as therein
expressed or by declaration or otherwise and irrespective of whether the Trustee
shall have made any demand on the Company or the Guarantor for the payment of
any overdue principal, premium, interest or Additional Amounts) shall be
entitled and empowered, by intervention in such proceeding or otherwise,

            (1) to file and prove a claim for the whole amount, or such lesser
      amount as may be provided for in the Securities of any applicable series,
      of the principal and any premium, interest and Additional Amounts owing
      and unpaid in respect of the Securities and any Coupons appertaining
      thereto and to file such other papers or documents as may be necessary or
      advisable in order to have the claims of the Trustee (including any claim
      for the reasonable compensation, expenses, disbursements and advances of
      the Trustee, its agents or counsel) and of the Holders of Securities or
      any Coupons appertaining thereto allowed in such judicial proceeding, and

            (2) to collect and receive any monies 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 of Securities or any Coupons 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 of Securities or any Coupons, to pay to the Trustee any
amount due to 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 6.6.


                                       48
<PAGE>

authorize or consent to or accept or adopt on behalf of any Holder of a Security
or any Coupon any plan of reorganization, arrangement, adjustment or composition
affecting the Securities or Coupons or the rights of any Holder thereof, or to
authorize the Trustee to vote in respect of the claim of any Holder of a
Security or any Coupon in any such proceeding.

      Section 5.5. Trustee May Enforce Claims without Possession of Securities
or Coupons.

Securities or Coupons may be prosecuted and enforced by the Trustee without the
possession of any of the Securities or Coupons or the production thereof in any
proceeding relating thereto, and any such proceeding instituted by the Trustee
shall be brought in its own name as trustee of an express trust, and any
recovery or judgment, after provision for the payment of the reasonable
compensation, expenses, disbursements and advances of the Trustee, its agents
and counsel, shall be for the ratable benefit of each and every Holder of the
Securities or Coupons in respect of which such judgment has been recovered.

      Any money collected by the Trustee pursuant to this Article shall be
applied in the following order, at the date or dates fixed by the Trustee and,
in case of the distribution of such money on account of principal, or any

Coupons, or both, as the case may be, and the notation thereon of the payment if

      kind, according to the aggregate amounts due and payable on such
      Securities and Coupons for principal and any premium, interest and
      Additional Amounts, respectively;

      of a continuing Event of Default with respect to the Securities of such
      series;

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, to the extent permitted by law, prevent the
concurrent assertion or employment of any other appropriate right or remedy.

      Section 5.11. Delay or Omission Not Waiver.

      No delay or omission of the Trustee or of any Holder of any Security or
Coupon to exercise any right or remedy accruing upon any Event of Default shall
impair any such right or remedy or constitute a waiver of any such Event of
Default or an acquiescence therein. Every right and remedy given by this Article
or by law to the Trustee or to any Holder of a Security or a Coupon may be
exercised from time to time, and as often as may be deemed expedient, by the
Trustee or by such Holder, as the case may be.

      Section 5.12. Control by Holders of Securities.

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

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

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

            (3) such direction is not unduly prejudicial to the rights of the
      other Holders of Securities of such series not joining in such action.

      Section 5.13. Waiver of Past Defaults.

      The Holders of not less than a majority in principal amount of the
Outstanding Securities of any series on behalf of the Holders of all the
Securities of such series and any Coupons appertaining thereto may waive any
past default hereunder with respect to such series and its consequences, except
a default


                                       51
<PAGE>

            (1) in the payment of the principal of, any premium or interest on,
      or any Additional Amounts with respect to, any Security of such series or
      any Coupons appertaining thereto, or

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

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

      Section 5.14. Waiver of Usury, Stay or Extension Laws .

      The Company and the Guarantor each covenants that (to the extent that it
may lawfully do so) it will not at any time insist upon, or plead, or in any
manner whatsoever claim or take the benefit or advantage of, any usury, stay or
extension law wherever enacted, now or at any time hereafter in force, which may
affect the covenants or the performance of this Indenture; and the Company and
the Guarantor each expressly waives (to the extent that it may lawfully do so)
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 5.15.     Undertaking for Costs.

      All parties to this Indenture agree, and each Holder of any Security by
his acceptance thereof shall be deemed to have agreed, that any court may in its
discretion require, in any suit for the enforcement of any right or remedy under
this Indenture, or in any suit against the Trustee for any action taken or
omitted by it as Trustee, the filing by any party litigant in such suit of any
undertaking to pay the costs of such suit, and that such court may in its
discretion assess reasonable costs, including reasonable attorneys' fees,
against any party litigant in such suit having due regard to the merits and good
faith of the claims or defenses made by such party litigant; but the provisions
of this Section 5.15 shall not apply to any suit instituted by the Trustee, to
any suit instituted by any Holder, or group of Holders, holding in the aggregate
more than 10% in principal amount of Outstanding Securities of any series, or to
any suit instituted by any Holder for the enforcement of the payment of the
principal of (or premium, if any) or interest, if any, on or Additional Amounts,
if any, with respect to any Security on or after the respective Stated
Maturities expressed in such Security (or, in the case of redemption, on or
after the Redemption Date, and, in the case of repayment, on or after the date
for repayment) or for the enforcement of the right, if any, to convert or
exchange any Security into other securities in accordance with its terms.

            (5) the Trustee shall be under no obligation to exercise any of the
      rights or powers vested in it by or pursuant to this Indenture at the
      request or direction of any of the Holders of Securities of any series or
      any Coupons appertaining thereto pursuant to this Indenture, unless such

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

      investigation, it shall be entitled to examine, during business hours and
      upon reasonable notice, the books, records and premises of the Company and
      the Guarantor, personally or by agent or attorney;

            (7) the Trustee may execute any of the trusts or powers hereunder or

            (8) the Trustee shall not be liable for any action taken or error of
      judgment made in good faith by a Responsible Officer or Responsible
      Officers of the Trustee, unless it shall be proved that the Trustee was
      negligent, acted in bad faith or engaged in willful misconduct;

            (9) the Authenticating Agent, Paying Agent, and Security Registrar
      shall have the same protections as the Trustee set forth hereunder; and

            (10) the Trustee shall not be liable with respect to any action

      discretion, relating to the time, method and place of conducting any
      proceeding for any remedy available to the Trustee, or exercising any
      trust or power conferred upon the Trustee, under this Indenture or any
      Securities, unless it shall be proved that, in connection with any such
      action taken, suffered or omitted or any such act, the Trustee was
      negligent, acted in bad faith or engaged in willful misconduct.

      Section 6.2. Notice of Defaults.

      Within 90 days after the occurrence of any default hereunder with respect
to the Securities of any series, the Trustee shall transmit by mail to all
Holders of Securities of such series entitled to receive reports pursuant to

provided, however, that, except in the case of a default in the payment of the
principal of (or premium, if any), or interest, if any, on, or Additional
Amounts or any sinking fund or purchase fund installment with respect to, any
Security of such series, the Trustee shall be protected in withholding such
notice if and so long as the board of directors, the executive committee or a
trust committee of directors and/or Responsible Officers of the Trustee in good
faith determine that the withholding of such notice is in the best interest of
the Holders of Securities and Coupons of such series; and provided, further,
that in the case of any default of the character specified in Section 5.1(5)
with respect to Securities of such series, no such notice to Holders shall be
given until at least 30 days after the occurrence thereof. For the purpose of
this Section, the term "default" means any event which is, or after notice or
lapse of time or both would become, an Event of Default with respect to
Securities of such series.

      Section 6.3. Not Responsible for Recitals or Issuance of Securities.

      The recitals contained herein and in the Securities, except the Trustee's
certificate of authentication, and in any Coupons shall be taken as the
statements of the Company or the Guarantor, as the case may be, and neither the
Trustee nor any Authenticating Agent assumes any responsibility for their
correctness. The Trustee makes no representations as to the validity or
sufficiency of this Indenture or of the Securities or the Coupons, except that
the Trustee represents that it is duly authorized to execute and deliver this
Indenture, authenticate the Securities and perform its obligations hereunder and
that the statements made by it in a Statement of Eligibility on Form T-1
supplied to the Company are true and accurate, subject to the qualifications set
forth therein. Neither the Trustee nor any Authenticating Agent shall be
accountable for the use or application by the Company of the Securities or the
proceeds thereof.

      Section 6.4. May Hold Securities.

      The Trustee, any Authenticating Agent, any Paying Agent, any Security
Registrar or any other Person that may be an agent of the Trustee or the
Guarantor or the Company, in its individual or any other capacity, may become
the owner or pledgee of Securities or Coupons and, subject to Sections 310(b)
and 311 of the Trust Indenture Act, may otherwise deal with the Company or the
Guarantor with the same rights it would have if it were not the Trustee,
Authenticating Agent, Paying Agent, Security Registrar or such other Person.

      Section 6.5. Money Held in Trust.

      Except as provided in Section 4.3 and Section 10.3, money held by the
Trustee in trust hereunder need not be segregated from other funds except to the

no liability for interest on any money received by it hereunder except as
otherwise agreed to in writing with the Company or the Guarantor.

      Section 6.6. Compensation and Reimbursement.

      The Company and the Guarantor (without duplication) each agree:

            (1) to pay to the Trustee from time to time reasonable compensation
      for all services rendered by the Trustee hereunder (which compensation
      shall not be limited by any provision of law in regard to the compensation
      of a trustee of an express trust);

            (2) except as otherwise expressly provided herein, to reimburse the
      Trustee upon its request for all reasonable expenses, disbursements and
      advances incurred or made by the Trustee in accordance with any provision
      of this Indenture or arising out of or in connection with the acceptance
      or administration of the trust or trusts hereunder (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 the Trustee's negligence or bad faith; and


                                       55
<PAGE>

            (3) to indemnify the Trustee and its agents, officers, directors and
      employees for, and to hold them harmless against, any loss, liability or
      expense incurred without negligence or bad faith on their part, arising
      out of or in connection with the acceptance or administration of the trust
      or trusts hereunder, including the costs and expenses of defending
      themselves against any claim or liability in connection with the exercise
      or performance of any of their powers or duties hereunder, except to the
      extent that any such loss, liability or expense was due to the Trustee's
      negligence or bad faith.

      As security for the performance of the obligations of the Company and the
Guarantor under this Section, the Trustee shall have a lien prior to the
Securities of any series upon all property and funds held or collected by the
Trustee as such, except funds held in trust for the payment of principal of, and
premium or interest on or any Additional Amounts with respect to Securities or
any Coupons appertaining thereto.

      To the extent permitted by law, any compensation or expense incurred by
the Trustee after a default specified in or pursuant to Section 5.1 is intended
to constitute an expense of administration under any then applicable bankruptcy
or insolvency law. "Trustee" for purposes of this Section 6.6 shall include any
predecessor Trustee but the negligence or bad faith of any Trustee shall not
affect the rights of any other Trustee under this Section 6.6.

      The provisions of this Section 6.6 shall survive the satisfaction and
discharge of this Indenture or the earlier resignation or removal of the Trustee
and shall apply with equal force and effect to the Trustee in its capacity as
Authenticating Agent, Paying Agent or Security Registrar.

      Section 6.7. Corporate Trustee Required; Eligibility.

surplus (computed in accordance with Section 310(a)(2) of the Trust Indenture
Act) of at least $50,000,000, and that is subject to supervision or examination
by Federal or state authority. If at any time the Trustee shall cease to be
eligible in accordance with the provisions of this Section, it shall resign
immediately in the manner and with the effect hereinafter specified in this
Article.

      Section 6.8. Resignation and Removal; Appointment of Successor.

            (1) No resignation or removal of the Trustee and no appointment of a
      successor Trustee pursuant to this Article shall become effective until
      the acceptance of appointment by the successor Trustee pursuant to Section
      6.9.

            (2) The Trustee may resign at any time with respect to the
      Securities of one or more series by giving written notice thereof to the
      Company and the Guarantor. If the instrument of acceptance by a successor

                                       56
<PAGE>

      been delivered to the Trustee within 30 days after the giving of such
      notice of resignation, the resigning Trustee may petition any court of
      competent jurisdiction for the appointment of a successor Trustee with

            imposed upon it under Section 310(b) of the Trust Indenture Act with
            respect to Securities of any series after written request therefor
            by the Company, the Guarantor or any Holder of a Security of such
            series who has been a bona fide Holder of a Security of such series
            for at least six months, or

                  (b) the Trustee shall cease to be eligible under Section 6.7
            and shall fail to resign after written request therefor by the
            Company, the Guarantor or any such Holder, or

                  (c) the Trustee shall become incapable of acting or shall be
            adjudged a bankrupt or insolvent or a receiver of the Trustee or of
            its property shall be appointed or any public officer shall take
            charge or control of the Trustee or of its property or affairs for
            the purpose of rehabilitation, conservation or liquidation, then, in
            any such case, (i) the Company, by or pursuant to a Board
            Resolution, or the Guarantor, by or pursuant to a Guarantor's Board
            Resolution, may remove the Trustee with respect to all Securities or
            the Securities of such series, or (ii) subject to Section 315(e) of
            the Trust Indenture Act, any Holder of a Security who has been a
            bona fide Holder of a Security of such series for at least six
            months may, on behalf of himself and all others similarly situated,
            petition any court of competent jurisdiction for the removal of the
            Trustee with respect to all Securities of such series and the
            appointment of a successor Trustee or Trustees.

            (5) If the Trustee shall resign, be removed or become incapable of
      acting, or if a vacancy shall occur in the office of Trustee for any
      cause, with respect to the Securities of one or more series, the Company,
      by or pursuant to a Board Resolution, and the Guarantor, by or pursuant to
      a Guarantor's Board Resolution, shall promptly appoint a successor Trustee
      or Trustees with respect to the Securities of such series (it being
      understood that any such successor Trustee may be appointed with respect
      to the Securities of one or more or all of such series and that at any
      time there shall be only one Trustee with respect to the Securities of any
      particular series) and shall comply with the applicable requirements of
      Section 6.9. If, within one year after such resignation, removal or
      incapacity, or the occurrence of such vacancy, a successor Trustee with
      respect to the Securities of any series shall be appointed by Act of the
      Holders of a majority in principal amount of the Outstanding Securities of
      such series delivered to the


                                       57

      appointed shall, forthwith upon its acceptance of such appointment in
      accordance with the applicable requirements of Section 6.9, become the
      successor Trustee with respect to the Securities of such series and to
      that extent supersede the successor Trustee appointed by the Company and
      the Guarantor. If no successor Trustee with respect to the Securities of
      any series shall have been so appointed by the Company and the Guarantor
      or the Holders of Securities and accepted appointment in the manner
      required by Section 6.9, any Holder of a Security who has been a bona fide
      Holder of a Security of such series for at least six months may, on behalf
      of himself and all others similarly situated, petition any court of
      competent jurisdiction for the appointment of a successor Trustee with
      respect to the Securities of such series.

            (6) The Company shall give notice of each resignation and each
      removal of the Trustee with respect to the Securities of any series and
      each appointment of a successor Trustee with respect to the Securities of
      any series by mailing written notice of such event by first-class mail,
      postage prepaid, to the Holders of Registered Securities, if any, of such
      series as their names and addresses appear in the Security Register and,
      if Securities of such series are issued as Bearer Securities, by
      publishing notice of such event once in an Authorized Newspaper in each
      Place of Payment located outside the United States. Each notice shall
      include the name of the successor Trustee with respect to the Securities
      of such series and the address of its Corporate Trust Office.

            (7) In no event shall any retiring Trustee be liable for the acts or
      omissions of any successor Trustee hereunder.

      Section 6.9. Acceptance of Appointment by Successor.

            (1) Upon the appointment hereunder of any successor Trustee with
      respect to all Securities, such successor Trustee so appointed shall
      execute, acknowledge and deliver to the Company, the Guarantor and the
      retiring Trustee an instrument accepting such appointment, and thereupon
      the resignation or removal of the retiring Trustee shall become effective
      and such successor Trustee, without any further act, deed or conveyance,
      shall become vested with all the rights, powers, trusts and duties
      hereunder of the retiring Trustee; but, on the request of the Company, the
      Guarantor or such successor Trustee, such retiring Trustee, upon payment
      of its charges, shall execute and deliver an instrument transferring to
      such successor Trustee all the rights, powers and trusts of the retiring
      Trustee and, subject to Section 10.3, shall duly assign, transfer and
      deliver to such successor Trustee all property and money held by such
      retiring Trustee hereunder, subject nevertheless to its claim, if any,
      provided for in Section 6.6.

            (2) Upon the appointment hereunder of any successor Trustee with
      respect to the Securities of one or more (but not all) series, the
      Company, the Guarantor, the retiring Trustee and such successor Trustee
      shall execute and deliver an indenture supplemental hereto wherein each
      successor Trustee shall accept such appointment and which (1) shall
      contain such provisions as shall be necessary or desirable to transfer and
      confirm to, and


                                       58

      duties of the retiring Trustee with respect to the Securities of that or
      those series to which the appointment of such successor Trustee relates,

      Securities, shall contain such provisions as shall be deemed necessary or
      desirable to confirm that all the rights, powers, trusts and duties of the
      retiring Trustee with respect to the Securities of that or those series as
      to which the retiring Trustee is not retiring shall continue to be vested
      in the retiring Trustee, and (3) shall add to or change any of the
      provisions of this Indenture as shall be necessary to provide for or
      facilitate the administration of the trusts hereunder by more than one
      Trustee, it being understood that nothing herein or in such supplemental
      indenture shall constitute such Trustees co-trustees of the same trust,
      that each such Trustee shall be trustee of a trust or trusts hereunder
      separate and apart from any trust or trusts hereunder administered by any
      other such Trustee and that no Trustee shall be responsible for any notice
      given to, or received by, or any act or failure to act on the part of any
      other Trustee hereunder, and, upon the execution and delivery of such
      supplemental indenture, the resignation or removal of the retiring Trustee
      shall become effective to the extent provided therein, such retiring
      Trustee shall have no further responsibility for the exercise of rights
      and powers or for the performance of the duties and obligations vested in
      the Trustee under this Indenture with respect to the Securities of that or
      those series to which the appointment of such successor Trustee relates
      other than as hereinafter expressly set forth, and such successor Trustee,
      without any further act, deed or conveyance, shall become vested with all
      the rights, powers, trusts and duties of the retiring Trustee with respect
      to the Securities of that or those series to which the appointment of such
      successor Trustee relates; but, on request of the Company, the Guarantor
      or such successor Trustee, such retiring Trustee, upon payment of its
      charges with respect to the Securities of that or those series to which
      the appointment of such successor Trustee relates and subject to Section
      10.3 shall duly assign, transfer and deliver to such successor Trustee, to
      the extent contemplated by such supplemental indenture, the property and
      money held by such retiring Trustee hereunder with respect to the
      Securities of that or those series to which the appointment of such
      successor Trustee relates, subject to its claim, if any, provided for in
      Section 6.6.

            (3) Upon request of any Person appointed hereunder as a successor
      Trustee, the Company and the Guarantor shall execute any and all
      instruments for more fully and certainly vesting in and confirming to such
      successor Trustee all such rights, powers and trusts referred to in
      paragraph (1) or (2) of this Section, as the case may be.

            (4) No Person shall accept its appointment hereunder as a successor

to which the Trustee shall be a party, shall be the successor of the Trustee
hereunder, without the execution or filing of any paper or any further act on
the part of any of the parties hereto. In case any Securities shall have been
authenticated but not delivered by the Trustee then in office, any successor by
merger, conversion or consolidation to such authenticating Trustee may adopt
such authentication and deliver the Securities so authenticated with the same
effect as if such successor Trustee had itself authenticated such Securities.

      Section 6.11. Appointment of Authenticating Agent.

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

      Each Authenticating Agent must be acceptable to the Company and the
Guarantor and, except as provided in or pursuant to this Indenture, shall at all
times be a corporation that would be permitted by the Trust Indenture Act to act
as trustee under an indenture qualified under the Trust Indenture Act, is
authorized under applicable law and by its charter to act as an Authenticating
Agent and has a combined capital and surplus (computed in accordance with
Section 310(a)(2) of the Trust Indenture Act) of at least $50,000,000. If at any
time an Authenticating Agent shall cease to be eligible in accordance with the
provisions of this Section, it shall resign immediately in the manner and with
the effect specified in this Section.

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

      An Authenticating Agent may resign at any time by giving written notice
thereof to the Trustee, the Company and the Guarantor. The Trustee may at any
time terminate the agency of an Authenticating Agent by giving written notice
thereof to such Authenticating Agent, the Company and the Guarantor. Upon
receiving such a notice of resignation or upon such a termination, or in case at
any time such Authenticating Agent shall cease to be eligible in accordance with
the provisions of this Section, the Trustee may appoint a successor
Authenticating Agent which shall be acceptable to the Company and the Guarantor
and shall (i) mail written notice of such appointment by first-class mail,
postage prepaid, to all Holders of


                                       60
<PAGE>

Registered Securities, if any, of the series with respect to which such
Authenticating Agent shall serve, as their names and addresses appear in the
Security Register, and (ii) if Securities of the series are issued as Bearer
Securities, publish notice of such appointment at least once in an Authorized
Newspaper in the place where such successor Authenticating Agent has its
principal office if such office is located outside the United States. Any
successor Authenticating Agent, upon acceptance of its appointment hereunder,
shall become vested with all the rights, powers and duties of its predecessor
hereunder, with like effect as if originally named as an Authenticating Agent.
No successor Authenticating Agent shall be appointed unless eligible under the
provisions of this Section.

      The Company and the Guarantor (without duplication) each agree to pay each
Authenticating Agent from time to time reasonable compensation for its services
under this Section. If the Trustee makes such payments, it shall be entitled to
be reimbursed for such payments, subject to the provisions of Section 6.6.

      The provisions of Sections 3.8, 6.3 and 6.4 shall be applicable to each
Authenticating Agent.

      If an Authenticating Agent is appointed with respect to one or more series
of Securities pursuant to this Section, the Securities of such series may have
endorsed thereon, in addition to or in lieu of the Trustee's certificate of
authentication, an alternate certificate of authentication in substantially the
following form:

      This is one of the Securities of the series designated herein referred to
in the within-mentioned Indenture.

                                    THE FIRST NATIONAL BANK OF CHICAGO,
                                     as Trustee

                                    By_______________________________________
                                       Authorized Officer

      If all of the Securities of any series may not be originally issued at one
time, and if the Trustee does not have an office capable of authenticating
Securities upon original issuance located in a Place of Payment where the
Company wishes to have Securities of such series authenticated upon original
issuance, the Trustee, if so requested in writing (which writing need not be
accompanied by or contained in an Officer's Certificate by the Company), shall
appoint in


                                       61

accordance with this Section an Authenticating Agent having an office in a Place
of Payment designated by the Company with respect to such series of Securities.

            (4) modify any of the provisions of this Section, Section 5.13 or
      Section 10.8, except to increase any such percentage or to provide that
      certain other provisions of this


                                       68
<PAGE>

      Indenture cannot be modified or waived without the consent of the Holder
      of each Outstanding Security affected thereby, or

            (5) make any change that adversely affects the right to convert or
      exchange any Security into or for securities of the Company or the
      Guarantor or other securities, (whether or not issued by the Company or
      the Guarantor) cash or property in accordance with its terms.

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

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

      Section 9.3. Execution of Supplemental Indentures .

      As a condition to executing, or accepting the additional trusts created
by, any supplemental indenture permitted by this Article or the modifications
thereby of the trust created by this Indenture, the Trustee shall be entitled to
receive, and (subject to Section 315 of the Trust Indenture Act) 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 and an
Officer's Certificate and Guarantor's Officer's Certificate stating that all
conditions precedent to the execution of such supplemental indenture have been
fulfilled. 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 9.4. Effect of Supplemental Indentures.

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

      Section 9.5. Reference in Securities to Supplemental Indentures.

      Securities of any series 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 Securities of any series so modified as to conform, in the
opinion of the Trustee and the Company, to any such supplemental indenture


                                       69
<PAGE>

may be prepared and executed by the Company and authenticated and delivered by
the Trustee in exchange for Outstanding Securities of such series.

      Section 9.6. Conformity with Trust Indenture Act.

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

      Section 9.7. Notice of Supplemental Indenture.

      Promptly after the execution by the Company, the Guarantor and the Trustee
of any supplemental indenture pursuant to Section 9.2, the Company shall
transmit to the Holders of Outstanding Securities of any series affected thereby
a notice setting forth the substance of such supplemental indenture.

                                  ARTICLE 10

                                  COVENANTS

      Section 10.1. Payment of Principal, any Premium, Interest and Additional
Amounts.

      The Company covenants and agrees for the benefit of the Holders of the
Securities of each series that it will duly and punctually pay the principal of,
any premium and interest on and any Additional Amounts with respect to the
Securities of such series in accordance with the terms thereof, any Coupons
appertaining thereto and this Indenture. Any interest due on any Bearer Security
on or before the Maturity thereof, and any Additional Amounts payable with
respect to such interest, shall be payable only upon presentation and surrender
of the Coupons appertaining thereto for such interest as they severally mature.

      Section 10.2. Maintenance of Office or Agency.

      The Company and the Guarantor shall maintain in each Place of Payment for
any series of Securities an Office or Agency where Securities of such series
(but not Bearer Securities, except as otherwise provided below, unless such
Place of Payment is located outside the United States) may be presented or
surrendered for payment, where Securities of such series may be surrendered for
registration of transfer or exchange, where Securities of such series that are
convertible or exchangeable may be surrendered for conversion or exchange, and
where notices and demands to or upon the Company or the Guarantor in respect of
the Securities of such series relating thereto and this Indenture may be served.
If Securities of a series are issuable as Bearer Securities, the Company and the
Guarantor shall maintain, subject to any laws or regulations applicable thereto,
an Office or Agency in a Place of Payment for such series which is located
outside the United States where Securities of such series and any Coupons
appertaining thereto may be presented and surrendered for payment; provided,
however, that if the Securities of such series are listed on The Stock Exchange
of the United Kingdom and the Republic of Ireland or the Luxembourg Stock
Exchange or any other stock exchange located outside the United States


                                       70
<PAGE>

and such stock exchange shall so require, the Company and the Guarantor shall
maintain a Paying Agent in London, Luxembourg or any other required city located
outside the United States, as the case may be, so long as the Securities of such
series are listed on such exchange. The Company and the Guarantor 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 or the Guarantor
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, except that Bearer Securities of such series and any Coupons
appertaining thereto may be presented and surrendered for payment at the place
specified for the purpose with respect to such Securities as provided in or
pursuant to this Indenture, and the Company and the Guarantor hereby appoint the
Trustee as their agent to receive all such presentations, surrenders, notices
and demands.

      Except as otherwise provided in or pursuant to this Indenture, no payment
of principal, premium, interest or Additional Amounts with respect to Bearer
Securities shall be made at any Office or Agency in the United States or by
check mailed to any address in the United States or by transfer to an account
maintained with a bank located in the United States; provided, however, if
amounts owing with respect to any Bearer Securities shall be payable in Dollars,
payment of principal of, any premium or interest on and any Additional Amounts
with respect to any such Security may be made at the Corporate Trust Office of
the Trustee or any Office or Agency designated by the Company and the Guarantor
in the Borough of Manhattan, The City of New York, if (but only if) payment of
the full amount of such principal, premium, interest or Additional Amounts at
all offices outside the United States maintained for such purpose by the Company
and the Guarantor in accordance with this Indenture is illegal or effectively
precluded by exchange controls or other similar restrictions.

      The Company and the Guarantor may also from time to time designate one or
more other Offices or Agencies where the Securities of one or more series 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 or the Guarantor of its
obligation to maintain an Office or Agency in each Place of Payment for
Securities of any series for such purposes. The Company and the Guarantor shall
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. Unless
otherwise provided in or pursuant to this Indenture, the Company and the
Guarantor hereby designate as the Place of Payment for each series of Securities
the Borough of Manhattan, The City of New York, and initially appoint the
Corporate Trust Office of the Trustee as the Office or Agency of the Company in
the Borough of Manhattan, The City of New York for such purpose. The Company and
the Guarantor may subsequently appoint a different Office or Agency in the
Borough of Manhattan, The City of New York for the Securities of any series.

      Unless otherwise specified with respect to any Securities pursuant to
Section 3.1, if and so long as the Securities of any series (i) are denominated
in a Foreign Currency or (ii) may be payable in a Foreign Currency, or so long
as it is required under any other provision of this


                                       71
<PAGE>

Indenture, then the Company will maintain with respect to each such series of
Securities, or as so required, at least one exchange rate agent.

      Section 10.3. Money for Securities Payments to Be Held in Trust.

      If the Company shall at any time act as its own Paying Agent, or if the
Guarantor shall act as Paying Agent, with respect to any series of Securities,
it shall, on or before each due date of the principal of, any premium or
interest on or Additional Amounts with respect to any of the Securities of such
series, segregate and hold in trust for the benefit of the Persons entitled
thereto a sum in the currency or currencies, currency unit or units or composite
currency or currencies in which the Securities of such series are payable
(except as otherwise specified pursuant to Section 3.1 for the Securities of
such series) sufficient to pay the principal or any premium, interest or
Additional Amounts so becoming due until such sums shall be paid to such Persons
or otherwise disposed of as herein provided, and shall promptly notify the
Trustee of its action or failure so to act.

      Whenever the Company shall have one or more Paying Agents for any series
of Securities, it shall, on or prior to each due date of the principal of, any
premium or interest on or any Additional Amounts with respect to any Securities
of such series, deposit with any Paying Agent a sum (in the currency or
currencies, currency unit or units or composite currency or currencies described
in the preceding paragraph) sufficient to pay the principal or any premium,
interest or Additional Amounts so becoming due, such sum to be held in trust for
the benefit of the Persons entitled thereto, 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 shall cause each Paying Agent for any series of Securities
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 shall:

            (1) hold all sums held by it for the payment of the principal of,
      any premium or interest on or any Additional Amounts with respect to
      Securities of such series in trust for the benefit of the Persons entitled
      thereto until such sums shall be paid to such Persons or otherwise
      disposed of as provided in or pursuant to this Indenture;

            (2) give the Trustee notice of any default by the Company or the
      Guarantor (or any other obligor upon the Securities of such series) in the
      making of any payment of principal, any premium or interest on or any
      Additional Amounts with respect to the Securities of such series; and

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

      The Company or the Guarantor may at any time, for the purpose of obtaining
the satisfaction and discharge of this Indenture or for any other purpose, pay,
or by Company Order


                                       72
<PAGE>

or Guarantor Order direct any Paying Agent to pay, to the Trustee all sums held
in trust by the Company, the Guarantor or such Paying Agent, such sums to be
held by the Trustee upon the same terms as those upon which such sums were held
by the Company, the Guarantor 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 sums.

      Except as otherwise provided herein or pursuant hereto, any money
deposited with the Trustee or any Paying Agent, or then held by the Company or
the Guarantor, in trust for the payment of the principal of, any premium or
interest on or any Additional Amounts with respect to any Security of any series
or any Coupon appertaining thereto and remaining unclaimed for two years after
such principal or any such premium or interest or any such Additional Amounts
shall have become due and payable shall be paid to the Company on Company
Request (or if deposited by the Guarantor, paid to the Guarantor on Guarantor
Request), or (if then held by the Company or the Guarantor) shall be discharged
from such trust; and the Holder of such Security or any Coupon appertaining
thereto shall thereafter, as an unsecured general creditor, look only to the
Company and the Guarantor for payment thereof, and all liability of the Trustee
or such Paying Agent with respect to such trust money, and all liability of the
Company as trustee thereof, shall thereupon cease; provided, however, that the
Trustee or such Paying Agent, before being required to make any such repayment,
may at the expense of the Company and the Guarantor cause to be published once,
in an Authorized Newspaper in each Place of Payment for such series or to be
mailed to Holders of Registered Securities of such series, or both, notice that
such money remains unclaimed and that, after a date specified therein, which
shall not be less than 30 days from the date of such publication or mailing nor
shall it be later than two years after such principal and any premium or
interest or Additional Amounts shall have become due and payable, any unclaimed
balance of such money then remaining will be repaid to the Company or the
Guarantor, as the case may be.

      Section 10.4. Additional Amounts.

      If any Securities of a series provide for the payment of Additional
Amounts, the Company agrees to pay to the Holder of any such Security or any
Coupon appertaining thereto Additional Amounts as provided in or pursuant to
this Indenture or such Securities. Whenever in this Indenture there is
mentioned, in any context, the payment of the principal of or any premium or
interest on, or in respect of, any Security of any series or any Coupon or the
net proceeds received on the sale or exchange of any Security of any series,
such mention shall be deemed to include mention of the payment of Additional
Amounts provided by the terms of such series established hereby or pursuant
hereto to the extent that, in such context, Additional Amounts are, were or
would be payable in respect thereof pursuant to such terms, and express mention
of the payment of Additional Amounts (if applicable) in any provision hereof
shall not be construed as excluding Additional Amounts in those provisions
hereof where such express mention is not made.

      Except as otherwise provided in or pursuant to this Indenture or the
Securities of the applicable series, if the Securities of a series provide for
the payment of Additional Amounts, at


                                       73
<PAGE>

least 10 days prior to the first Interest Payment Date with respect to such
series of Securities (or if the Securities of such series shall not bear
interest prior to Maturity, the first day on which a payment of principal is
made), and at least 10 days prior to each date of payment of principal or
interest if there has been any change with respect to the matters set forth in
the below-mentioned Officer's Certificate, the Company shall furnish to the
Trustee and the principal Paying Agent or Paying Agents, if other than the
Trustee, an Officer's Certificate instructing the Trustee and such Paying Agent
or Paying Agents whether such payment of principal of and premium, if any, or
interest on the Securities of such series shall be made to Holders of Securities
of such series or the Coupons appertaining thereto who are United States Aliens
without withholding for or on account of any tax, assessment or other
governmental charge described in the Securities of such series. If any such
withholding shall be required, then such Officer's Certificate shall specify by
country the amount, if any, required to be withheld on such payments to such
Holders of Securities or Coupons, and the Company agrees to pay to the Trustee
or such Paying Agent the Additional Amounts required by the terms of such
Securities. The Company covenants to indemnify the Trustee and any Paying Agent
for, and to hold them harmless against, any loss, liability or expense
reasonably incurred without negligence or bad faith on their part arising out of
or in connection with actions taken or omitted by any of them in reliance on any
Officer's Certificate furnished pursuant to this Section 10.4.

      Section 10.5. Limitation on Liens on Stock of Designated Subsidiaries.

      So long as any Securities are Outstanding, neither the Company nor the
Guarantor will, nor will it permit any of its respective Subsidiaries to,
create, assume, incur, guarantee or otherwise permit to exist any Indebtedness
secured by any mortgage, pledge, lien, security interest or other encumbrance (a
"Lien") upon any shares of Capital Stock of any Designated Subsidiary (whether
such shares of stock are now owned or hereafter acquired) without effectively
providing concurrently that the Securities (and, if the Company and the
Guarantor so elect, any other Indebtedness of the Company that is not
subordinate to the Securities and with respect to which the governing
instruments require, or pursuant to which the Company is otherwise obligated, to
provide such security) shall be secured equally and ratably with such
Indebtedness for at least the time period such other Indebtedness is so secured.

      Section 10.6. Limitation on Disposition of Stock of Designated
Subsidiaries.

      So long as any Securities are outstanding and except in a transaction
otherwise governed by this Indenture, neither the Company nor the Guarantor will
issue, sell, assign, transfer or otherwise dispose of any shares of, securities
convertible into, or warrants, rights or options to subscribe for or purchase
shares of, Capital Stock (other than Preferred Stock having no voting rights of
any kind) of any Designated Subsidiary, and will not permit any Designated
Subsidiary (other than to the Company or the Guarantor) to issue any shares
(other than the director's qualifying shares) of, or securities convertible
into, or warrants, rights or options to subscribe for or purchase shares of,
Capital Stock (other than Preferred Stock having no voting rights of any kind)
of any Designated Subsidiary, if, after giving effect to any such transaction
and the issuance of the maximum number of shares issuable upon the conversion or
exercise of all such


                                       74
<PAGE>

convertible securities, warrants, rights or options, the Company or the
Guarantor, as the case may be, would own, directly or indirectly, less than 80%
of the shares of Capital Stock of such Designated Subsidiary (other than
Preferred Stock having no voting rights of any kind); provided, however, that
(i) any issuance, sale, assignment, transfer or other disposition permitted by
the Company or the Guarantor may only be made for at least a fair market value
consideration as determined by the Board of Directors or the Guarantor's Board
of Directors, as the case may be, pursuant to a Board Resolution or Guarantor's
Board Resolution, as the case may be, adopted in good faith and (ii) the
foregoing shall not prohibit any such issuance or disposition of securities if
required by any law or any regulation or order of any governmental or insurance
regulatory authority. Notwithstanding the foregoing, (i) the Company or the
Guarantor, as the case may be, may merge or consolidate any Designated
Subsidiary into or with another direct or indirect Subsidiary of the Guarantor,
the shares of capital stock of which the Guarantor owns at least 80%, and (ii)
the Company or the Guarantor, as the case may be, may, subject to the provisions
of Article 8, sell, assign, transfer or otherwise dispose of the entire Capital
Stock of any Designated Subsidiary at one time for at least a fair market value
consideration as determined by the Board of Directors or Guarantor's Board of
Directors, as the case may be, pursuant to a Board Resolution or Guarantor's
Board Resolution, as the case may be, adopted in good faith.

      Section 10.7. Corporate Existence.

      Subject to Article 8, the Company and the Guarantor shall do or cause to
be done all things necessary to preserve and keep in full force and effect their
respective corporate existences and that of each of their respective
Subsidiaries and their respective rights (charter and statutory) and franchises;
provided, however, that the foregoing shall not obligate the Company or the
Guarantor or any of their respective Subsidiaries to preserve any such right or
franchise if the Company, the Guarantor or any such Subsidiary shall determine
that the preservation thereof is no longer desirable in the conduct of its
business or the business of such Subsidiary and that the loss thereof is not
disadvantageous in any material respect to any Holder.

      Section 10.8. Waiver of Certain Covenants.

      The Company or the Guarantor, as the case may be, may omit in any
particular instance to comply with any term, provision or condition set forth in
Section 10.5, 10.6 or 10.7 with respect to the Securities of any series if
before the time for such compliance the Holders of at least a majority in
principal amount of the Outstanding Securities of such series, by Act of such
Holders, either shall waive such compliance in such instance or generally shall
have waived compliance with such term, provision or condition, but no such
waiver shall extend to or affect such term, provision or condition except to the
extent so expressly waived, and, until such waiver shall become effective, the
obligations of the Company and the Guarantor and the duties of the Trustee in
respect of any such term, provision or condition shall remain in full force and
effect.

                           REDEMPTION OF SECURITIES

      Section 11.1. Applicability of Article.

      Redemption of Securities of any series at the option of the Company as
permitted or required by the terms of such Securities shall be made in
accordance with the terms of such Securities and (except as otherwise provided
herein or pursuant hereto) this Article.

      Section 11.2. Election to Redeem; Notice to Trustee.

      The election of the Company to redeem any Securities shall be evidenced by
or pursuant to a Board Resolution. In case of any redemption at the election of
the Company of (a) less than all of the Securities of any series or (b) all of
the Securities of any series, with the same issue date, interest rate or
formula, Stated Maturity and other terms, the Company shall, at least 60 days
prior to the Redemption Date fixed by the Company (unless a shorter notice shall
be satisfactory to the Trustee), notify the Trustee of such Redemption Date and
of the principal amount of Securities of such series to be redeemed.

      Section 11.3. Selection by Trustee of Securities to be Redeemed.

      If less than all of the Securities of any series with the same issue date,
interest rate or formula, Stated Maturity and other terms are to be redeemed,
the particular Securities to be redeemed shall be selected not more than 60 days
prior to the Redemption Date by the Trustee from the Outstanding Securities of
such series not previously called for redemption, by such method as the Trustee
shall deem fair and appropriate and which may provide for the selection for
redemption of portions of the principal amount of Registered Securities of such
series; provided, however, that no such partial redemption shall reduce the
portion of the principal amount of a Registered Security of such series not
redeemed to less than the minimum denomination for a Security of such series
established herein or pursuant hereto.


                                       77
<PAGE>

      The Trustee shall promptly notify the Company and the Security Registrar
(if other than itself) in writing of the Securities selected for redemption and,
in the case of any Securities selected for partial redemption, the principal
amount thereof to be redeemed.

      For all purposes of this Indenture, unless the context otherwise requires,
all provisions relating to the redemption of Securities shall relate, in the
case of any Securities redeemed or to be redeemed only in part, to the portion
of the principal of such Securities which has been or is to be redeemed.

      Unless otherwise specified in or pursuant to this Indenture or the
Securities of any series, if any Security selected for partial redemption is
converted into other securities of the Company or exchanged for securities of
the Guarantor or another issuer in part before termination of the conversion or
exchange right with respect to the portion of the Security so selected, the
converted portion of such Security shall be deemed (so far as may be) to be the
portion selected for redemption. Securities which have been converted or
exchanged during a selection of Securities to be redeemed shall be treated by
the Trustee as Outstanding for the purpose of such selection.

      Section 11.4. Notice of Redemption.

      Notice of redemption shall be given in the manner provided in Section 1.6,
not less than 30 nor more than 60 days prior to the Redemption Date, unless a
shorter period is specified in the Securities to be redeemed, to the Holders of
Securities to be redeemed. Failure to give notice by mailing in the manner
herein provided to the Holder of any Registered Securities designated for
redemption as a whole or in part, or any defect in the notice to any such
Holder, shall not affect the validity of the proceedings for the redemption of
any other Securities or portion thereof.

      Any notice that is mailed to the Holder of any Registered Securities in
the manner herein provided shall be conclusively presumed to have been duly
given, whether or not such Holder receives the notice.

      All notices of redemption shall state:

            (1) the Redemption Date,

            (2) the Redemption Price,

            (3) if less than all Outstanding Securities of any series are to be
      redeemed, the identification (and, in the case of partial redemption, the
      principal amount) of the particular Security or Securities to be redeemed,

            (4) in case any Security is to be redeemed in part only, the notice
      which relates to such Security shall state that on and after the
      Redemption Date, upon surrender of such Security, the Holder of such
      Security will receive, without charge, a new Security


                                       78
<PAGE>

      or Securities of authorized denominations for the principal amount thereof
      remaining unredeemed,

            (5) that, on the Redemption Date, the Redemption Price shall become
      due and payable upon each such Security or portion thereof to be redeemed,
      and, if applicable, that interest thereon shall cease to accrue on and
      after said date,

            (6) the place or places where such Securities, together (in the case
      of Bearer Securities) with all Coupons appertaining thereto, if any,
      maturing after the Redemption Date, are to be surrendered for payment of
      the Redemption Price and any accrued interest and Additional Amounts
      pertaining thereto,

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

            (8) that, unless otherwise specified in such notice, Bearer
      Securities of any series, if any, surrendered for redemption must be
      accompanied by all Coupons maturing subsequent to the date fixed for
      redemption or the amount of any such missing Coupon or Coupons will be
      deducted from the Redemption Price, unless security or indemnity
      satisfactory to the Company, the Guarantor, the Trustee and any Paying
      Agent is furnished,

            (9) if Bearer Securities of any series are to be redeemed and no
      Registered Securities of such series are to be redeemed, and if such
      Bearer Securities may be exchanged for Registered Securities not subject
      to redemption on the Redemption Date pursuant to Section 3.5 or otherwise,
      the last date, as determined by the Company, on which such exchanges may
      be made,

            (10) in the case of Securities of any series that are convertible
      into Common Stock of the Company or exchangeable for other securities, the
      conversion or exchange price or rate, the date or dates on which the right
      to convert or exchange the principal of the Securities of such series to
      be redeemed will commence or terminate and the place or places where such
      Securities may be surrendered for conversion or exchange, and

            (11) the CUSIP number or the Euroclear or the Cedel reference
      numbers of such Securities, if any (or any other numbers used by a
      Depository to identify such Securities).

      A notice of redemption published as contemplated by Section 1.6 need not
identify particular Registered Securities to be redeemed.

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

      Section 11.5. Deposit of Redemption Price.

      On or prior to any Redemption Date, the Company or the Guarantor shall
deposit, with respect to the Securities of any series called for redemption
pursuant to Section 11.4, with the Trustee or with a Paying Agent (or, if the
Company is acting as its own Paying Agent or the Guarantor is acting as Paying
Agent, segregate and hold in trust as provided in Section 10.3) an amount of
money in the applicable Currency sufficient to pay the Redemption Price of, and
(except if the Redemption Date shall be an Interest Payment Date, unless
otherwise specified pursuant to Section 3.1 or in the Securities of such series)
any accrued interest on and Additional Amounts with respect thereto, all such
Securities or portions thereof which are to be redeemed on that date.

      Section 11.6. Securities Payable on Redemption Date.

      Notice of redemption having been given as aforesaid, the Securities 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 and the Guarantor shall default in the payment of the Redemption Price
and accrued interest) such Securities shall cease to bear interest and the
Coupons for such interest appertaining to any Bearer Securities so to be
redeemed, except to the extent provided below, shall be void. Upon surrender of
any such Security for redemption in accordance with said notice, together with
all Coupons, if any, appertaining thereto maturing after the Redemption Date,
such Security shall be paid by the Company at the Redemption Price, together
with any accrued interest and Additional Amounts to the Redemption Date;
provided, however, that, except as otherwise provided in or pursuant to this
Indenture or the Bearer Securities of such series, installments of interest on
Bearer Securities whose Stated Maturity is on or prior to the Redemption Date
shall be payable only upon presentation and surrender of Coupons for such
interest (at an Office or Agency located outside the United States except as
otherwise provided in Section 10.2), and provided, further, that, except as
otherwise specified in or pursuant to this Indenture or the Registered
Securities of such series, installments of interest on Registered Securities
whose Stated Maturity is on or prior to the Redemption Date shall be payable to
the Holders of such Securities, or one or more Predecessor Securities,
registered as such at the close of business on the Regular Record Dates therefor
according to their terms and the provisions of Section 3.7.

      If any Bearer Security surrendered for redemption shall not be accompanied
by all appurtenant Coupons maturing after the Redemption Date, such Security may
be paid after deducting from the Redemption Price an amount equal to the face
amount of all such missing Coupons, or the surrender of such missing Coupon or
Coupons may be waived by the Company and the Trustee if there be furnished to
them such security or indemnity as they may require to save each of them and any
Paying Agent harmless. If thereafter the Holder of such Security shall surrender
to the Trustee or any Paying Agent any such missing Coupon in respect of which a
deduction shall have been made from the Redemption Price, such Holder shall be
entitled to receive the amount so deducted; provided, however, that any interest
or Additional Amounts represented by Coupons shall be payable only upon
presentation and surrender of those Coupons


                                       80
<PAGE>

at an Office or Agency for such Security located outside of the United States
except as otherwise provided in Section 10.2.

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

      Section 11.7. Securities Redeemed in Part.

      Any Registered Security which is to be redeemed only in part shall be
surrendered at any Office or Agency for such Security (with, if the Company or
the Trustee so requires, 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 deliver to the Holder of such
Security without service charge, a new Registered Security or Securities of the
same series, containing identical terms and provisions, 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 Security so
surrendered. If a Security in global form is so surrendered, the Company shall
execute, and the Trustee shall authenticate and deliver to the U.S. Depository
or other Depository for such Security in global form as shall be specified in
the Company Order with respect thereto to the Trustee, without service charge, a
new Security in global form in a denomination equal to and in exchange for the
unredeemed portion of the principal of the Security in global form so
surrendered.

                                SINKING FUNDS

      Section 12.1. Applicability of Article.

      The provisions of this Article shall be applicable to any sinking fund for
the retirement of Securities of a series, except as otherwise permitted or
required in or pursuant to this Indenture or any Security of such series issued
pursuant to this Indenture.

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

      Section 12.2. Satisfaction of Sinking Fund Payments with Securities.

      The Company or the Guarantor may, in satisfaction of all or any part of
any sinking fund payment with respect to the Securities of any series to be made
pursuant to the terms of such Securities (1) deliver Outstanding Securities of
such series (other than any of such Securities previously called for redemption
or any of such Securities in respect of which cash shall have been released to
the Company), together in the case of any Bearer Securities of such series with
all unmatured Coupons appertaining thereto, and (2) apply as a credit Securities
of such series which have been redeemed either at the election of the Company
pursuant to the terms of such series of Securities or through the application of
permitted optional sinking fund payments pursuant to the terms of such
Securities, provided that such series of Securities have not been previously so
credited. Such Securities shall be received and credited for such purpose by the
Trustee at the Redemption Price specified in such Securities for redemption
through operation of the sinking fund and the amount of such sinking fund
payment shall be reduced accordingly. If, as a result of the delivery or credit
of Securities of any series in lieu of cash payments pursuant to this Section
12.2, the principal amount of Securities of such series to be redeemed in order
to satisfy the remaining sinking fund payment shall be less than $100,000, the
Trustee need not call Securities of such series for redemption, except upon
Company Request or Guarantor Request, and such cash payment shall be held by the
Trustee or a Paying Agent and applied to the next succeeding sinking fund
payment, provided, however, that the Trustee or such Paying Agent shall at the
request of the Company or the Guarantor from time to time pay over and deliver
to the Company or the Guarantor, as the case may be, any cash payment so being
held by the Trustee or such Paying Agent upon delivery by the Company or the
Guarantor to the Trustee of Securities of that series purchased by the Company
or the Guarantor having an unpaid principal amount equal to the cash payment
requested to be released to the Company or the Guarantor.

      Section 12.3. Redemption of Securities for Sinking Fund.

      Not less than 75 days prior to each sinking fund payment date for any
series of Securities, the Company shall deliver to the Trustee an Officer's
Certificate specifying the amount of the next ensuing mandatory sinking fund
payment for that series pursuant to the terms of that series, the portion
thereof, if any, which is to be satisfied by payment of cash and the portion
thereof, if any, which is to be satisfied by delivering and crediting of
Securities of that series pursuant to Section 12.2, and the optional amount, if
any, to be added in cash to the next ensuing mandatory sinking fund payment, and
will also deliver to the Trustee any Securities to be so credited and not
theretofore delivered. If such Officer's Certificate shall specify an optional
amount to be added in cash to the next ensuing mandatory sinking fund payment,
the Company shall thereupon be obligated to pay the amount therein specified.
Not less than 60 days before each such sinking fund payment date the Trustee
shall select the Securities to be redeemed upon such sinking fund payment date
in the manner specified in Section 11.3 and cause notice of the redemption
thereof to be given in the name of and at the expense of the Company in the
manner provided in Section 11.4. Such notice having been duly given, the
redemption of such Securities shall be made upon the terms and in the manner
stated in Sections 11.6 and 11.7.

                      REPAYMENT AT THE OPTION OF HOLDERS

      Section 13.1. Applicability of Article.

      Securities of any series which are repayable at the option of the Holders
thereof before their Stated Maturity shall be repaid in accordance with the
terms of the Securities of such series. The repayment of any principal amount of
Securities pursuant to such option of the Holder to require repayment of
Securities before their Stated Maturity, for purposes of Section 3.9, shall not
operate as a payment, redemption or satisfaction of the Indebtedness represented
by such Securities unless and until the Company, at its option, shall deliver or
surrender the same to the Trustee with a directive that such Securities be
cancelled. Notwithstanding anything to the contrary contained in this Section
13.1, in connection with any repayment of Securities, the Company may arrange
for the purchase of any Securities by an agreement with one or more investment
bankers or other purchasers to purchase such Securities by paying to the Holders
of such Securities on or before the close of business on the repayment date an
amount not less than the repayment price payable by the Company on repayment of
such Securities, and the obligation of the Company to pay the repayment price of
such Securities shall be satisfied and discharged to the extent such payment is
so paid by such purchasers.

      Section 14.1. Applicability of Article.

      Whenever this Indenture provides for (i) any action by, or the
determination of any of the rights of, Holders of Securities of any series in
which not all of such Securities are denominated in the same Currency, or (ii)
any distribution to Holders of Securities, in the absence of any provision to
the contrary in the form of Security of any particular series or pursuant to
this Indenture or the Securities, any amount in respect of any Security
denominated in a Currency other than Dollars shall be treated for any such
action or distribution as that amount of Dollars that could be obtained for such
amount on such reasonable basis of exchange and as of the record date with
respect to Registered Securities of such series (if any) for such action,
determination of rights or distribution (or, if there shall be no applicable
record date, such other date reasonably proximate to the date of such action,
determination of rights or distribution) as the Company or the Guarantor may
specify in a written notice to the Trustee.

                      MEETINGS OF HOLDERS OF SECURITIES

      Section 15.1. Purposes for Which Meetings May Be Called.

      A meeting of Holders of Securities of any series may be called at any time
and from time to time pursuant to this Article to make, give or take any
request, demand, authorization, direction, notice, consent, waiver or other Act
provided by this Indenture to be made, given or taken by Holders of Securities
of such series.

      Section 15.2. Call, Notice and Place of Meetings.

            (1) The Trustee may at any time call a meeting of Holders of
      Securities of any series for any purpose specified in Section 15.1, to be
      held at such time and at such place in the Borough of Manhattan, The City
      of New York, or, if Securities of such series have been issued in whole or
      in part as Bearer Securities, in London or in such place outside the
      United States as the Trustee shall determine. Notice of every meeting of
      Holders of Securities of any series, setting forth the time and the place
      of such meeting and in general terms the action proposed to be taken at
      such meeting, shall be given, in the manner provided in Section 1.6, not
      less than 21 nor more than 180 days prior to the date fixed for the
      meeting.

            (2) In case at any time the Company (by or pursuant to a Board
      Resolution), the Guarantor (by or pursuant to a Guarantor's Board
      Resolution) or the Holders of at least 10% in principal amount of the
      Outstanding Securities of any series shall have requested the Trustee to
      call a meeting of the Holders of Securities of such series for any purpose
      specified in Section 15.1, by written request setting forth in reasonable
      detail the action proposed to be taken at the meeting, and the Trustee
      shall not have mailed notice of or made the first publication of the
      notice of such meeting within 21 days after receipt of such request
      (whichever shall be required pursuant to Section 1.6) or shall not
      thereafter proceed to cause the meeting to be held as provided herein,
      then the Company, the Guarantor or the Holders of Securities of such
      series in the amount above specified, as the case may be, may determine
      the time and the place in the Borough of Manhattan, The City of New York,
      or, if Securities of such series are to be issued as Bearer Securities, in

      Section 15.4. Quorum; Action.

      The Persons entitled to vote a majority in principal amount of the
Outstanding Securities of a series shall constitute a quorum for any meeting of
Holders of Securities of such series. In the absence of a quorum within 30

convened at the request of Holders of Securities of such series, be dissolved.
In any other case the meeting may be adjourned for a period of not less than 10
days as determined by the chairman of the meeting prior to the adjournment of
such meeting. In the absence of a quorum at any reconvened meeting, such
reconvened meeting may be further adjourned for a period of not less than 10
days as determined by the chairman of the meeting prior to the adjournment of
such reconvened meeting. Notice of the reconvening of any adjourned meeting
shall be given as provided in Section 15.2(1), except that such notice need be
given only once not less than five days prior to the date on which the meeting
is scheduled to be reconvened. Notice of the reconvening of an adjourned meeting
shall state expressly the percentage, as provided above, of the principal amount
of the Outstanding Securities of such series which shall constitute a quorum.

      Except as limited by the proviso to Section 9.2, any resolution presented
to a meeting or adjourned meeting duly reconvened at which a quorum is present
as aforesaid may be adopted only by the affirmative vote of the Holders of a
majority in principal amount of the Outstanding Securities of that series;
provided, however, that, except as limited by the proviso to Section 9.2, any
resolution with respect to any request, demand, authorization, direction,
notice, consent, waiver or other Act which this Indenture expressly provides may
be made, given or taken by the Holders of a specified percentage, which is less
than a majority, in principal amount of the Outstanding Securities of a series
may be adopted at a meeting or an adjourned meeting duly reconvened and at which
a quorum is present as aforesaid by the affirmative vote of the Holders of such
specified percentage in principal amount of the Outstanding Securities of such
series.

      Any resolution passed or decision taken at any meeting of Holders of

binding on all the Holders of Securities of such series and the Coupons
appertaining thereto, whether or not such Holders were present or represented at
the meeting.

      Section 15.5. Determination of Voting Rights; Conduct and Adjournment of
Meetings.

            (1) Notwithstanding any other provisions of this Indenture, the
      Trustee may make such reasonable regulations as it may deem advisable for
      any meeting of Holders of Securities of such series in regard to proof of
      the holding of Securities of such series and of the appointment of proxies
      and in regard to the appointment and duties of inspectors of votes, the
      submission and examination of proxies, certificates and other evidence of
      the right to vote, and such other matters concerning the conduct of the
      meeting as it shall


                                       85
<PAGE>

      deem appropriate. Except as otherwise permitted or required by any such
      regulations, the holding of Securities shall be proved in the manner
      specified in Section 1.4 and the appointment of any proxy shall be proved
      in the manner specified in Section 1.4 or by having the signature of the
      person executing the proxy witnessed or guaranteed by any trust company,
      bank or banker authorized by Section 1.4 to certify to the holding of
      Bearer Securities. Such regulations may provide that written instruments
      appointing proxies, regular on their face, may be presumed valid and
      genuine without the proof specified in Section 1.4 or other proof.

            (2) The Trustee shall, by an instrument in writing, appoint a
      temporary chairman of the meeting, unless the meeting shall have been
      called by the Company or by Holders of Securities as provided in Section
      15.2(2), in which case the Company, the Guarantor or the Holders of
      Securities of the series calling the meeting, as the case may be, shall in
      like manner appoint a temporary chairman. A permanent chairman and a
      permanent secretary of the meeting shall be elected by vote of the Persons
      entitled to vote a majority in principal amount of the Outstanding
      Securities of such series represented at the meeting.

            (3) At any meeting, each Holder of a Security of such series or
      proxy shall be entitled to one vote for each $1,000 principal amount of
      Securities of such series held or represented by him; provided, however,
      that no vote shall be cast or counted at any meeting in respect of any
      Security challenged as not Outstanding and ruled by the chairman of the
      meeting to be not Outstanding. The chairman of the meeting shall have no
      right to vote, except as a Holder of a Security of such series or proxy.

            (4) Any meeting of Holders of Securities of any series duly called
      pursuant to Section 15.2 at which a quorum is present may be adjourned
      from time to time by Persons entitled to vote a majority in principal
      amount of the Outstanding Securities of such series represented at the
      meeting; and the meeting may be held as so adjourned without further
      notice.

      Section 15.6. Counting Votes and Recording Action of Meetings.

      The vote upon any resolution submitted to any meeting of Holders of
Securities of any series shall be by written ballots on which shall be
subscribed the signatures of the Holders of Securities of such series or of
their representatives by proxy and the principal amounts and serial numbers of
the Outstanding Securities of such series held or represented by them. The
permanent chairman of the meeting shall appoint two inspectors of votes who
shall count all votes cast at the meeting for or against any resolution and who
shall make and file with the secretary of the meeting their verified written
reports in triplicate of all votes cast at the meeting. A record, at least in
triplicate, of the proceedings of each meeting of Holders of Securities of any
series shall be prepared by the secretary of the meeting and there shall be
attached to said record the original reports of the inspectors of votes on any
vote by ballot taken thereat and affidavits by one or more persons having
knowledge of the facts setting forth a copy of the notice of the meeting and
showing that said notice was given as provided in Section 15.2 and, if
applicable,

Section 15.4. Each copy shall be signed and verified by the affidavits of the
permanent chairman and secretary of the meeting and one such copy shall be
delivered to the Company and the Guarantor, and another to the Trustee to be
preserved by the Trustee, the latter to have attached thereto the ballots voted
at the meeting. Any record so signed and verified shall be conclusive evidence
of the matters therein stated.

                           GUARANTEE AND INDEMNITY

      Section 16.1. The Guarantee.

      The Guarantor hereby unconditionally guarantees to each Holder of a
Security authenticated and delivered by the Trustee the due and punctual payment
of the principal of, any premium and interest on, and any Additional Amounts
with respect to such Security and the due and punctual payment of the sinking
fund payments (if any) provided for pursuant to the terms of such Security, when
and as the same shall become due and payable, whether at maturity, by
acceleration, redemption, repayment or otherwise, in accordance with the terms
of such Security and of this Indenture. In case of the failure of the Company
punctually to pay any such principal, premium, interest, Additional Amounts or
sinking fund payment, the Guarantor hereby agrees to cause any such payment to
be made punctually when and as the same shall become due and payable, whether at
maturity, upon acceleration, redemption, repayment or otherwise, and as if such
payment were made by the Company.

      Section 16.2. Net Payments.

      All payments of principal of and premium, if any, interest and any other
amounts on, or in respect of, the Securities of any series or any Coupon
appertaining thereto shall be made by the Guarantor without withholding or
deduction at source for, or on account of, any present or future taxes, fees,
duties, assessments or governmental charges of whatever nature imposed or levied
by or on behalf of the Cayman Islands or Bermuda (each, a "taxing jurisdiction")
or any political subdivision or taxing authority thereof or therein, unless such
taxes, fees, duties, assessments or governmental charges are required to be
withheld or deducted by (i) the laws (or any regulations or ruling promulgated
thereunder) of a taxing jurisdiction or any political subdivision or taxing
authority thereof or therein or (ii) an official position regarding the
application, administration, interpretation or enforcement of any such laws,
regulations or rulings (including, without limitation, a holding by a court of
competent jurisdiction or by a taxing authority in a taxing jurisdiction or any
political subdivision thereof). If a withholding or deduction at source is
required, the Guarantor shall, subject to certain limitations and exceptions set
forth below, pay to the Holder of any such Security or any Coupon appertaining
thereto such Additional Amounts as may be necessary so that every net payment of
principal, premium, if any, interest or any other amount made to such Holder,
after such withholding or deduction, shall not be less than the amount provided
for in such Security, any Coupons appertaining thereto and this Indenture to be
then due and payable; provided, however, that the Guarantor shall not be
required to make payment of such Additional Amounts for or on account of:

            (1) any tax, fee, duty, assessment or governmental charge of
      whatever nature which would not have been imposed but for the fact that
      such Holder: (A) was a resident, domiciliary or national of, or engaged in
      business or maintained a permanent establishment or was physically present
      in, the relevant taxing jurisdiction or any political subdivision thereof
      or otherwise had some connection with the relevant taxing jurisdiction
      other than by reason of the mere ownership of, or receipt of payment
      under, such Security; (B) presented such Security for payment in the
      relevant taxing jurisdiction or any political subdivision thereof, unless
      such Security could not have been presented for payment elsewhere; or (C)
      presented such Security more than thirty (30) days after the date on which
      the payment in respect of such Security first became due and payable or
      provided for, whichever is later, except to the extent that the Holder
      would have been entitled to such Additional Amounts if it had presented
      such Security for payment on any day within such period of thirty (30)
      days;

            (2) any estate, inheritance, gift, sale, transfer, personal property
      or similar tax, assessment or other governmental charge;

            (3) any tax, assessment or other governmental charge that is imposed
      or withheld by reason of the failure by the Holder or the beneficial owner
      of such Security to comply with any reasonable request by the Guarantor
      addressed to the Holder within 90 days of such request (A) to provide
      information concerning the nationality, residence or identity of the
      Holder or such beneficial owner or (B) to make any declaration or other
      similar claim or satisfy any information or reporting requirement, which,
      in the case of (A) or (B), is required or imposed by statute, treaty,
      regulation or administrative practice of the relevant taxing jurisdiction
      or any political subdivision thereof as a precondition to exemption from
      all or part of such tax, assessment or other governmental charge; or

            (4) any combination of items (1), (2) and (3);

nor shall Additional Amounts be paid with respect to any payment of the
principal of, or premium, if any, interest or any other amounts on, any such
Security to any Holder who is a fiduciary or partnership or other than the sole
beneficial owner of such Security to the extent such payment would be required
by the laws of the relevant taxing jurisdiction (or any political subdivision or
relevant taxing authority thereof or therein) to be included in the income for
tax purposes of a beneficiary or partner or settlor with respect to such
fiduciary or a member of such partnership or a beneficial owner who would not
have been entitled to such Additional Amounts had it been the Holder of the
Security.

      Whenever in this Indenture there is mentioned, in any context, the payment
of the principal of or any premium, interest or any other amounts on, or in
respect of, any Security of any series or any Coupon or the net proceeds
received on the sale or exchange of any Security of any series, such mention
shall be deemed to include mention of the payment of Additional Amounts provided
by the terms of such series established hereby or pursuant hereto to the extent
that, in such context, Additional Amounts are, were or would be payable in
respect thereof pursuant to such terms, and express mention of the payment of
Additional Amounts (if


                                       88
<PAGE>

applicable) in any provision hereof shall not be construed as excluding the
payment of Additional Amounts in those provisions hereof where such express
mention is not made.

      Except as otherwise provided in or pursuant to this Indenture or the
Securities of the applicable series, at least 10 days prior to the first
Interest Payment Date with respect to a series of Securities (or if the
Securities of such series shall not bear interest prior to Maturity, the first
day on which a payment of principal is made), and at least 10 days prior to each
date of payment of principal or interest if there has been any change with
respect to the matters set forth in the below-mentioned Guarantor's Officer's
Certificate, the Guarantor shall furnish to the Trustee and the principal Paying
Agent or Paying Agents, if other than the Trustee, a Guarantor's Officer's
Certificate instructing the Trustee and such Paying Agent or Paying Agents
whether such payment of principal of and premium, if any, interest or any other
amounts on the Securities of such series shall be made to Holders of Securities
of such series or the Coupons appertaining thereto without withholding for or on
account of any tax, fee, duty, assessment or other governmental charge described
in this Section 16.2. If any such withholding shall be required, then such
Guarantor's Officer's Certificate shall specify by taxing jurisdiction the
amount, if any, required to be withheld on such payments to such Holders of
Securities or Coupons, and the Guarantor agrees to pay to the Trustee or such
Paying Agent the Additional Amounts required by this Section 16.2. The Guarantor
covenants to indemnify the Trustee and any Paying Agent for, and to hold them
harmless against, any loss, liability or expense reasonably incurred without
negligence or bad faith on their part arising out of or in connection with
actions taken or omitted by any of them in reliance on any Guarantor's Officer's
Certificate furnished pursuant to this Section 16.2.

      Section 16.3. Guarantee Unconditional, etc.

      The Guarantor hereby agrees that its obligations hereunder shall be as
principal and not merely as surety, and shall be absolute, irrevocable and
unconditional, irrespective of, and shall be unaffected by, any invalidity,
irregularity or unenforceability of any Security or this Indenture, any failure
to enforce the provisions of any Security or this Indenture, or any waiver,
modification, consent or indulgence granted with respect thereto by the Holder
of such Security or the Trustee, the recovery of any judgment against the
Company or any action to enforce the same, or any other circumstances which may
otherwise constitute a legal or equitable discharge of a surety or guarantor.
The Guarantor hereby waives diligence, presentment, demand of payment, filing of
claims with a court in the event of merger, insolvency or bankruptcy of the
Company, any right to require a proceeding first against the Company, protest or
notice with respect to any such Security or the Indebtedness evidenced thereby
and all demands whatsoever, and covenants that this Guarantee will not be
discharged except by payment in full of the principal of, any premium and
interest on, and any Additional Amounts and sinking fund payments required with
respect to, the Securities and the complete performance of all other obligations
contained in the Securities. The Guarantor further agrees, to the fullest extent
that it lawfully may do so, that, as between the Guarantor, on the one hand, and
the Holders and the Trustee, on the other hand, the Maturity of the obligations
guaranteed hereby may be accelerated as provided in Section 5.2 hereof for the
purposes of this Guarantee, notwithstanding any stay,


                                       89
<PAGE>

injunction or prohibition extant under any bankruptcy, insolvency,
reorganization or other similar law of any jurisdiction preventing such
acceleration in respect of the obligations guaranteed hereby.

      Section 16.4. Reinstatement.

      This Guarantee shall continue to be effective or be reinstated, as the
case may be, if at any time payment on any Security, in whole or in part, is
rescinded or must otherwise be restored to the Company or the Guarantor upon the
bankruptcy, liquidation or reorganization of the Company or otherwise.

      Section 16.5. Subrogation.

      The Guarantor shall be subrogated to all rights of the Holder of any
Security against the Company in respect of any amounts paid to such Holder by
the Guarantor pursuant to the provisions of this Guarantee; provided, however,
that the Guarantor shall not be entitled to enforce, or to receive any payments
arising out of or based upon, such right of subrogation until the principal of,
any premium and interest on, and any Additional Amounts and sinking fund
payments required with respect to, all Securities shall have been paid in full.

      Section 16.6. Indemnity.

      As a separate and alternative stipulation, the Guarantor unconditionally
and irrevocably agrees that any sum expressed to be payable by the Company under
this Indenture, the Securities or the Coupons but which is for any reason
(whether or not now known or becoming known to the Company, the Guarantor, the
Trustee or any Holder of any Security or Coupon) not recoverable from the
Guarantor on the basis of a guarantee will nevertheless be recoverable from it
as if it were the sole principal debtor and will be paid by it to the Trustee on
demand. This indemnity constitutes a separate and independent obligation from
the other obligations in this Indenture, gives rise to a separate and
independent cause of action and will apply irrespective of any indulgence
granted by the Trustee or any Holder of any Security or Coupon.

      demand, authorization, direction, notice, consent, waiver or other Act

      provide its proxy or proxies to the beneficial owners of interests in any
      such global Security through such U.S. Depository's standing instructions
      and customary practices.

      appointed in writing, any request, demand, authorization, direction,
      notice, consent, waiver or other Act provided in or pursuant to this
      Indenture to be made, given or taken by Holders. If such a record date is
      fixed, the Holders on such record date or their duly appointed proxy or
      proxies, and only such Persons, shall be


                                       16
<PAGE>

      entitled to make, give or take such request, demand, authorization,
      direction, notice, consent, waiver or other Act, whether or not such
      Holders remain Holders after such record date. No such request, demand,
      authorization, direction, notice, consent, waiver or other Act shall be
      valid or effective if made, given or taken more than 90 days after such
      record date.

           (2) The fact and date of the execution by any Person of any such
      instrument or writing referred to in this Section 1.4 may be proved in any
      reasonable manner; and the Trustee may in any instance require further
      proof with respect to any of the matters referred to in this Section.

           (3) The ownership, principal amount and serial numbers of
      Registered Securities held by any Person, and the date of the commencement
      and the date of the termination of holding the same, shall be proved by
      the Security Register.

           (4) The ownership, principal amount and serial numbers of Bearer
      Securities held by any Person, and the date of the commencement and the
      date of the termination of holding the same, may be proved by the
      production of such Bearer Securities or by a certificate executed, as
      depositary, by any trust company, bank, banker or other depositary
      reasonably acceptable to the Company and the Guarantor, wherever situated,
      if such certificate shall be deemed by the Company, the Guarantor and the
      Trustee to be satisfactory, showing that at the date therein mentioned
      such Person had on deposit with such depositary, or exhibited to it, the
      Bearer Securities therein described; or such facts may be proved by the
      certificate or affidavit of the Person holding such Bearer Securities, if
      such certificate or affidavit is deemed by the Trustee to be satisfactory.
      The Trustee, the Company and the Guarantor may assume that such ownership
      of any Bearer Security continues until (i) another certificate or
      affidavit bearing a later date issued in respect of the same Bearer
      Security is produced, or (ii) such Bearer Security is produced to the
      Trustee by some other Person, or (iii) such Bearer Security is surrendered
      in exchange for a Registered Security, or (iv) such Bearer Security is no
      longer Outstanding. The ownership, principal amount and serial numbers of
      Bearer Securities held by the Person so executing such instrument or
      writing and the date of the commencement and the date of the termination
      of holding the same may also be proved in any other manner which the
      Company, the Guarantor and the Trustee deem sufficient.

           (5) If the Company or the Guarantor shall solicit from the Holders
      of any Registered Securities any request, demand, authorization,
      direction, notice, consent, waiver or other Act, the Company or the
      Guarantor, as the case may be, may at its option (but is not obligated
      to), by Board Resolution or Guarantor's Board Resolution, as the case may
      be, fix in advance a record date for the determination of Holders of
      Registered Securities entitled to give such request, demand,
      authorization, direction, notice, consent, waiver or other Act. If such a
      record date is fixed, such request, demand, authorization, direction,
      notice, consent, waiver or other Act may be given before or after such
      record date, but only the Holders of Registered Securities of record at
      the close of business on


                                       17
<PAGE>

      such record date shall be deemed to be Holders for the purpose of
      determining whether Holders of the requisite proportion of Outstanding
      Securities have authorized or agreed or consented to such request, demand,
      authorization, direction, notice, consent, waiver or other Act, and for
      that purpose the Outstanding Securities shall be computed as of such
      record date; provided that no such authorization, agreement or consent by
      the Holders of Registered Securities shall be deemed effective unless it
      shall become effective pursuant to the provisions of this Indenture not
      later than six months after the record date.

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

      Section 1.5. Notices, etc. to Trustee, Company and Guarantor.

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

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

           (2) the Company or the Guarantor, as the case may be, by the
      Trustee or 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 or the Guarantor, as the case
      may be, addressed to the attention of its Treasurer, with a copy to the
      attention of its General Counsel, 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 or
      the Guarantor, as the case may be.

      Section 1.6. Notice to Holders of Securities; Waiver.

      Except as otherwise expressly provided in or pursuant to this Indenture,
where this Indenture provides for notice to Holders of Securities of any event,

           (1) such notice shall be sufficiently given to Holders of
      Registered Securities if in writing and mailed, first-class postage
      prepaid, to each Holder of a Registered Security affected by such event,
      at his address as it appears in the Security Register, not later than the
      latest date, and not earlier than the earliest date, prescribed for the
      giving of such notice; and


                                       18
<PAGE>

           (2) such notice shall be sufficiently given to Holders of Bearer
      Securities, if any, if published in an Authorized Newspaper in The City of
      New York and, if such Securities are then listed on any stock exchange
      outside the United States, in an Authorized Newspaper in such city as the
      Company shall advise the Trustee that such stock exchange so requires, on
      a Business Day at least twice, the first such publication to be not
      earlier than the earliest date and the second such publication not later
      than the latest date prescribed for the giving of such notice.

      In any case where notice to Holders of Registered Securities is given by
mail, neither the failure to mail such notice, nor any defect in any notice so
mailed, to any particular Holder of a Registered Security shall affect the
sufficiency of such notice with respect to other Holders of Registered
Securities or the sufficiency of any notice to Holders of Bearer Securities
given as provided herein. Any notice which is mailed in the manner herein
provided shall be conclusively presumed to have been duly given or provided. In
the 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.

      In case by reason of the suspension of publication of any Authorized
Newspaper or Authorized Newspapers or by reason of any other cause it shall be
impracticable to publish any notice to Holders of Bearers Securities as provided
above, then such notification to Holders of Bearer Securities as shall be given
with the approval of the Trustee shall constitute sufficient notice to such
Holders for every purpose hereunder. Neither failure to give notice by
publication to Holders of Bearer Securities as provided above, nor any defect in
any notice so published, shall affect the sufficiency of any notice mailed to
Holders of Registered Securities as provided above.

      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 of Securities shall be filed with the Trustee, but
such filing shall not be a condition precedent to the validity of any action
taken in reliance upon such waiver.

      Section 1.7. Language of Notices.

      Any request, demand, authorization, direction, notice, consent, election
or waiver required or permitted under this Indenture shall be in the English
language, except that, if the Company or the Guarantor, as the case may be, so
elects, any published notice may be in an official language of the country of
publication.

      Section 1.8. Conflict with Trust Indenture Act.

      If any provision hereof limits, qualifies or conflicts with any duties
under any required provision of the Trust Indenture Act imposed hereon by
Section 318(c) thereof, such required provision shall control.

be invalid, illegal or unenforceable, the validity, legality and enforceability
of the remaining provisions shall not in any way be affected or impaired
thereby.

Beneficiaries.

      The Company and the Guarantor hereby acknowledge that, to the extent
specifically set forth herein, the holders of the Preferred Securities of an ACE
Trust shall expressly be third party beneficiaries of this Indenture. The
Company and the Guarantor further acknowledge that, if an Event of Default has
occurred and is continuing and is attributable to the failure of the Company and
the Guarantor to pay the principal of or premium, if any, or interest on or
Additional Amounts with respect to the Securities of the series held by such ACE
Trust, any holder of the Preferred Securities of such ACE Trust may institute a
Direct Action against the Company or the Guarantor.

      Section 1.13. Benefits of Indenture.

      Except as other expressly provided herein with respect to holders of
Preferred Securities, nothing in this Indenture, any Security or any Coupon,
express or implied, shall give to any Person, other than the parties hereto and
the holders of Senior Indebtedness, any Security Registrar, any Paying Agent,
any Authenticating Agent and their successors hereunder and the Holders of
Securities or Coupons, any benefit or any legal or equitable right, remedy or
claim under this Indenture.

      Section 1.14. Governing Law.

      Section 1.15. Legal Holidays.

      Unless otherwise specified in or pursuant to this Indenture or any
Securities, in any case where any Interest Payment Date, Stated Maturity or
Maturity of any Security, or the last date on which a Holder has the right to
convert or exchange Securities of a series that are convertible or exchangeable,
shall not be a Business Day at any Place of Payment, then (notwithstanding any
other provision of this Indenture, any Security or any Coupon other than a
provision in any Security or Coupon that specifically states that such provision
shall apply in lieu hereof) payment need not be made at such Place of Payment on
such date, and such Securities need not be converted or exchanged on such date,
but such payment may be made, and such Securities may be converted or exchanged,
on the next succeeding day that is a Business Day at such Place of Payment, and
no interest shall accrue on the amount payable on such date or at such time for
the period from and after such Interest Payment Date, Stated Maturity, Maturity
or last day for conversion or exchange, as the case may be, to such next
succeeding Business Day, except that if such next succeeding Business Day is in
the next succeeding calendar year, such payment may be made, and such Securities
may be converted or exchanged, on the immediately preceding Business Day (in the
case of each of the foregoing, with the same force and effect as if made on such
Interest Payment Date or at such Stated Maturity or Maturity or on such last day
for conversion or exchange, as the case may be).

      The Company and the Guarantor each agrees, to the fullest extent that it
may effectively do so under applicable law, that (a) if for the purpose of
obtaining judgment in any court it is necessary to convert the sum due in
respect of the principal of, or premium or interest, if any, or Additional
Amounts on the Securities of any series (the "Required Currency") into a
currency in which a judgment will be rendered (the "Judgment Currency"), the
rate of exchange used shall be the rate at which in accordance with normal
banking procedures the Trustee could purchase in The City of New York the
requisite amount of the Required Currency with the Judgment Currency on the New
York Banking Day preceding the day on which a final unappealable judgment is
given and (b) its obligations under this Indenture to make payments in the
Required Currency (i) shall not be discharged or satisfied by any tender, or any
recovery pursuant to any judgment (whether or not entered in accordance with
clause (a)), in any currency other than the Required Currency, except to the
extent that such tender or recovery shall result in the actual receipt, by the
payee, of the full amount of the Required Currency expressed to be payable in
respect of such payments, (ii) shall be enforceable as an alternative or
additional cause of action for the purpose of recovering in the Required
Currency the amount, if any, by which such actual receipt shall fall short of
the full amount of the Required Currency so expressed to be payable and (iii)
shall not be affected by judgment being obtained for any other sum due under
this Indenture. For purposes of the foregoing, "New York Banking Day" means any
day except a


                                       21

be construed to constitute a security interest under the Uniform Commercial Code
or similar legislation, as now or hereafter enacted and in effect in any
jurisdiction where property of the Company, the Guarantor or their respective
Subsidiaries is or may be located.

      Section 1.19. Limitation on Individual Liability.

      No recourse under or upon any obligation, covenant or agreement contained
in this Indenture or in any Security, or for any claim based thereon or
otherwise in respect thereof, shall be had against any incorporator, shareholder
(except in a shareholder's corporate capacity as Guarantor), officer or
director, as such, past, present or future, of the Company or the Guarantor, as
the case may be, either directly or through the Company or the Guarantor, as the
case may be, whether by virtue of any constitution, statute or rule of law, or
by the enforcement of any assessment or penalty or otherwise; it being expressly
understood that this Indenture and the obligations issued hereunder are solely
corporate obligations, and that no such personal liability whatever shall attach
to, or is or shall be incurred by, the incorporators, shareholders, officers or
directors, as such, of the Company or the Guarantor, as the case may be, or any
of them, because of the creation of the indebtedness hereby authorized, or under
or by reason of the obligations, covenants or agreements contained in this
Indenture or in any Security or implied therefrom; and that any and all such
personal liability of every name and nature, either at common law or in equity
or by constitution or statute, of, and any and all such rights and claims
against, every such incorporator, shareholder, officer or director, as such,

reason of the obligations, covenants or agreements contained in this Indenture
or in any Security or implied therefrom, are hereby expressly waived and
released as a condition of, and as a consideration for, the execution of this
Indenture and the issuance of such Security.

      Section 1.20. Submission to Jurisdiction.

      The Company and the Guarantor each agrees that any judicial proceedings
instituted in relation to any matter arising under this Indenture, the
Securities or any Coupons appertaining thereto may be brought in any United
States Federal or New York State court sitting in the Borough of Manhattan, The

shall have no responsibility with respect to any failure by the Company or the
Guarantor to take any such action. Nothing herein shall affect the right to

accompanied by or contained in an Officer's Certificate and need not be
accompanied by an Opinion of Counsel.

            (15) if other than Dollars, the Foreign Currency in which payment of

      with respect to any of such Securities shall be payable;


                                       27
<PAGE>

            (16) if the principal of, any premium or interest on or any
      Additional Amounts with respect to any of such Securities are to be
      payable, at the election of the Company or a Holder thereof or otherwise,
      in Dollars or in a Foreign Currency other than that in which such

      Currency;

            (17) whether the amount of payments of principal of, any premium or
      interest on or any Additional Amounts with respect to such Securities may
      be determined with reference to an index, formula or other method or
      methods (which index, formula or method or methods may be based, without
      limitation, on one or more Currencies, commodities, equity securities,
      equity indices or other indices), and, if so, the terms and conditions
      upon which and the manner in which such amounts shall be determined and

            (20) whether either or both of Section 4.2(2) relating to defeasance

      to the Securities of such series, or any covenants in addition to those
      specified in Section 4.2(3) relating to the Securities of such series
      which shall be subject to covenant defeasance, and any deletions from, or
      modifications or additions to, the provisions of Article 4 in respect of
      the Securities of such series;

            (21) the form or forms of the Trust Agreement (if different from the
      form attached hereto as Annex A), Amended and Restated Trust Agreement and

                                       28
<PAGE>

            (23) if any of such Securities are to be issuable in global form and
      are to be issuable in definitive form (whether upon original issue or upon
      exchange of a temporary Security) only upon receipt of certain
      certificates or other documents or satisfaction of other conditions, then
      the form and terms of such certificates, documents or conditions;

            (24) if there is more than one Trustee, the identity of the Trustee
      and, if not the Trustee, the identity of each Security Registrar, Paying
      Agent or Authenticating Agent with respect to such Securities; and

           (25) any other terms of such Securities and any other deletions
      from or modifications or additions to this Indenture in respect of such
      Securities.

      All Securities of any one series and all Coupons, if any, appertaining to
Bearer Securities of such series shall be substantially identical except as to
Currency of payments due thereunder, denomination and the rate of interest
thereon, or method of determining the rate of interest, if any, Maturity, and
the date from which interest, if any, shall accrue and except as may otherwise
be provided by the Company in or pursuant to the Board Resolution and set forth
in the Officer's Certificate or in any indenture or indentures supplemental
hereto pertaining to such series of Securities. The terms of the Securities of
any series may provide, without limitation, that the Securities shall be
authenticated and delivered by the Trustee on original issue from time to time
upon written order of persons designated in the Officer's Certificate or
supplemental indenture and that such persons are authorized to determine,
consistent with such Officer's Certificate or any applicable supplemental
indenture, such terms and conditions of the Securities of such series as are
specified in such Officer's Certificate or supplemental indenture. All
Securities of any one series need not be issued at the same time and, unless
otherwise so provided, a series may be reopened for issuances of additional
Securities of such series or to establish additional terms of such series of
Securities.

      If any of the terms of the Securities of any series shall be established
by action taken by or pursuant to a Board Resolution, the Board Resolution shall
be delivered to the Trustee at or prior to the delivery of the Officer's
Certificate setting forth the terms of such series.

      Section 3.2. Currency; Denominations.

      Unless otherwise provided in or pursuant to this Indenture, the principal
of, any premium and interest on and any Additional Amounts with respect to the
Securities shall be payable in Dollars. Unless otherwise provided in or pursuant
to this Indenture, Registered Securities denominated in Dollars shall be
issuable in registered form without Coupons in denominations of $1,000 and any
integral multiple thereof, and the Bearer Securities denominated in Dollars
shall be issuable in the denomination of $5,000. Securities not denominated in
Dollars shall be issuable in such denominations as are established with respect
to such Securities in or pursuant to this Indenture.

      Section 3.3. Execution, Authentication, Delivery and Dating.

      Securities shall be executed on behalf of the Company by its Chairman of
the Board, a Vice Chairman, its President, its Treasurer or a Vice President
under its corporate seal reproduced thereon and attested by its Secretary or one
of its Assistant Secretaries. Coupons shall be executed on behalf of the Company
by the Treasurer or any Assistant Treasurer of the Company. The signature of any
of these officers on the Securities or any Coupons appertaining thereto may be
manual or facsimile.

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

      At any time and from time to time after the execution and delivery of this
Indenture, the Company may deliver Securities, together with any Coupons
appertaining thereto, executed by the Company, to the Trustee for authentication
and, provided that the Board Resolution and Officer's Certificate or
supplemental indenture or indentures with respect to such Securities referred to
in Section 3.1 and a Company Order for the authentication and delivery of such
Securities have been delivered to the Trustee, the Trustee in accordance with
the Company Order and subject to the provisions hereof and of such Securities
shall authenticate and deliver such Securities. In authenticating such
Securities, and accepting the additional responsibilities under this Indenture
in relation to such Securities and any Coupons appertaining thereto, the Trustee
shall be entitled to receive, and (subject to Sections 315(a) through 315(d) of
the Trust Indenture Act) shall be fully protected in relying upon,

      (1) an Opinion of Counsel to the effect that:

            (a) the form or forms and terms of such Securities and Coupons, if
      any, have been established in conformity with the provisions of this
      Indenture;

            (b) all conditions precedent to the authentication and delivery of
      such Securities and Coupons, if any, appertaining thereto, have been
      complied with and that such Securities and Coupons, when completed by
      appropriate insertions, executed under the Company's corporate seal and
      attested by duly authorized officers of the Company, delivered by duly
      authorized officers of the Company to the Trustee for authentication
      pursuant to this Indenture, and authenticated and delivered by the Trustee
      and issued by the Company in the manner and subject to any conditions
      specified in such Opinion of Counsel, will constitute legally valid and
      binding obligations of the Company, enforceable against the Company in
      accordance with their terms, except as enforcement thereof may be subject
      to or limited by bankruptcy, insolvency, reorganization, moratorium,
      arrangement, fraudulent conveyance, fraudulent transfer or other similar
      laws relating to or affecting creditors' rights generally, and subject to
      general principles of equity (regardless of whether enforcement is sought
      in a proceeding in equity or at


                                       30
<PAGE>

      law) and will entitle the Holders thereof to the benefits of this
      Indenture, including the Guarantee; such Opinion of Counsel need express
      no opinion as to the availability of equitable remedies;

            (c) all laws and requirements in respect of the execution and
      delivery by the Company of such Securities and Coupons, if any, have been
      complied with; and

            (d) this Indenture has been qualified under the Trust Indenture Act;
      and

      (2) an Officer's Certificate and a Guarantor's Officer's Certificate, in
each case stating that, to the best knowledge of the Persons executing such
certificate, all conditions precedent to the execution, authentication and
delivery of such Securities and Coupons, if any, appertaining thereto, have been
complied with, and no event which is, or after notice or lapse of time would
become, an Event of Default with respect to any of the Securities shall have
occurred and be continuing.

      If all the Securities of any series are not to be issued at one time, it
shall not be necessary to deliver an Opinion of Counsel and an Officer's
Certificate and Guarantor's Officer's Certificate at the time of issuance of
each Security, but such opinion and certificates, with appropriate
modifications, shall be delivered at or before the time of issuance of the first
Security of such series. After any such first delivery, any separate written
request by an Authorized Officer of the Company or any person designated in
writing by an Authorized Officer that the Trustee authenticate and deliver
Securities of such series for original issue will be deemed to be a
certification by the Company and the Guarantor that all conditions precedent
provided for in this Indenture relating to authentication and delivery of such
Securities continue to have been complied with and that no Event of Default with
respect to any of the Securities has occurred or is continuing.

      The Trustee shall not be required to authenticate or to cause an
Authenticating Agent to authenticate any Securities if the issue of such
Securities pursuant to this Indenture will affect the Trustee's own rights,
duties or immunities under the Securities and this Indenture or otherwise in a
manner which is not reasonably acceptable to the Trustee or if the Trustee,
being advised by counsel, determines that such action may not lawfully be taken.

      Each Registered Security shall be dated the date of its authentication.
Each Bearer Security and any Bearer Security in global form shall be dated as of
the date specified in or pursuant to this Indenture.

      No Security or Coupon appertaining thereto shall be entitled to any
benefit under this Indenture or be valid or obligatory for any purpose, unless
there appears on such Security a certificate of authentication substantially in
the form provided for in Section 2.2 or 6.11 executed by or on behalf of the
Trustee or by the Authenticating Agent by the manual signature of one of its
authorized officers. Such certificate upon any Security shall be conclusive
evidence, and the only evidence, that such Security has been duly authenticated
and delivered hereunder. Except


                                       31
<PAGE>

as permitted by Section 3.6 or 3.7, the Trustee shall not authenticate and
deliver any Bearer Security unless all Coupons appertaining thereto then matured
have been detached and cancelled.

      Section 3.4. Temporary Securities.

      Pending the preparation of definitive Securities, the Company may execute
and deliver to the Trustee and, upon Company Order, the Trustee shall
authenticate and deliver, in the manner provided in Section 3.3, temporary
Securities in lieu thereof which are printed, lithographed, typewritten,
mimeographed or otherwise produced, in any authorized denomination,
substantially of the tenor of the definitive Securities in lieu of which they
are issued, in registered form or, if authorized in or pursuant to this
Indenture, in bearer form with one or more Coupons or without Coupons and with
such appropriate insertions, omissions, substitutions and other variations as
the officers of the Company executing such Securities may determine, as
conclusively evidenced by their execution of such Securities. Such temporary
Securities may be in global form.

      Except in the case of temporary Securities in global form, which shall be
exchanged in accordance with the provisions thereof, if temporary Securities are
issued, the Company shall cause definitive Securities to be prepared without
unreasonable delay. After the preparation of definitive Securities of the same
series and containing terms and provisions that are identical to those of any
temporary Securities, such temporary Securities shall be exchangeable for such
definitive Securities upon surrender of such temporary Securities at an Office
or Agency for such Securities, without charge to any Holder thereof. Upon
surrender for cancellation of any one or more temporary Securities (accompanied
by any unmatured Coupons appertaining thereto), the Company shall execute and
the Trustee shall authenticate and deliver in exchange therefor a like principal
amount of definitive Securities of authorized denominations of the same series
and containing identical terms and provisions; provided, however, that no
definitive Bearer Security, except as provided in or pursuant to this Indenture,
shall be delivered in exchange for a temporary Registered Security; and
provided, further, that a definitive Bearer Security shall be delivered in
exchange for a temporary Bearer Security only in compliance with the conditions
set forth in or pursuant to this Indenture. Unless otherwise provided in or
pursuant to this Indenture with respect to a temporary global Security, until so
exchanged the temporary Securities of any series shall in all respects be
entitled to the same benefits under this Indenture as definitive Securities of
such series.

      Section 3.5. Registration, Transfer and Exchange.

      With respect to the Registered Securities of each series, if any, the
Company shall cause to be kept a register (each such register being herein
sometimes referred to as the "Security Register") at an Office or Agency for
such series in which, subject to such reasonable regulations as it may
prescribe, the Company shall provide for the registration of the Registered
Securities of such series and of transfers of the Registered Securities of such
series. Such Office or Agency shall be the "Security Registrar" for that series
of Securities. Unless otherwise specified in or pursuant to this Indenture or
the Securities, the Trustee shall be the initial Security Registrar for each
series of Securities. The Company shall have the right to remove and replace
from time to time the Security Registrar for any series of Securities; provided
that no such removal or


                                       32
<PAGE>

replacement shall be effective until a successor Security Registrar with respect
to such series of Securities shall have been appointed by the Company and shall
have accepted such appointment by the Company. In the event that the Trustee
shall not be or shall cease to be Security Registrar with respect to a series of
Securities, it shall have the right to examine the Security Register for such
series at all reasonable times. There shall be only one Security Register for
each series of Securities.

      Upon surrender for registration of transfer of any Registered Security of
any series at any Office or Agency for such series, the Company shall execute,
and the Trustee shall authenticate and deliver, in the name of the designated
transferee or transferees, one or more new Registered Securities of the same
series denominated as authorized in or pursuant to this Indenture, of a like
aggregate principal amount bearing a number not contemporaneously outstanding
and containing identical terms and provisions.

      At the option of the Holder, Registered Securities of any series may be
exchanged for other Registered Securities of the same series containing
identical terms and provisions, in any authorized denominations, and of a like
aggregate principal amount, upon surrender of the Securities to be exchanged at
any Office or Agency for such series. Whenever any Registered Securities are so
surrendered for exchange, the Company shall execute, and the Trustee shall
authenticate and deliver, the Registered Securities which the Holder making the
exchange is entitled to receive.

      If provided in or pursuant to this Indenture, with respect to Securities
of any series, at the option of the Holder, Bearer Securities of such series may
be exchanged for Registered Securities of such series containing identical
terms, denominated as authorized in or pursuant to this Indenture and in the
same aggregate principal amount, upon surrender of the Bearer Securities to be
exchanged at any Office or Agency for such series, with all unmatured Coupons
and all matured Coupons in default thereto appertaining. If the Holder of a
Bearer Security is unable to produce any such unmatured Coupon or Coupons or
matured Coupon or Coupons in default, such exchange may be effected if the
Bearer Securities are accompanied by payment in funds acceptable to the Company,
the Guarantor and the Trustee in an amount equal to the face amount of such
missing Coupon or Coupons, or the surrender of such missing Coupon or Coupons
may be waived by the Company, the Guarantor and the Trustee if there is
furnished to them such security or indemnity as they may require to save each of
them and any Paying Agent harmless. If thereafter the Holder of such Bearer
Security shall surrender to any Paying Agent any such missing Coupon in respect
of which such a payment shall have been made, such Holder shall be entitled to
receive the amount of such payment; provided, however, that, except as otherwise
provided in Section 10.2, interest represented by Coupons shall be payable only
upon presentation and surrender of those Coupons at an Office or Agency for such
series located outside the United States. Notwithstanding the foregoing, in case
a Bearer Security of any series is surrendered at any such Office or Agency for
such series in exchange for a Registered Security of such series and like tenor
after the close of business at such Office or Agency on (i) any Regular Record
Date and before the opening of business at such Office or Agency on the next
succeeding Interest Payment Date, or (ii) any Special Record Date and before the
opening of


                                       33
<PAGE>

business at such Office or Agency on the related date for payment of Defaulted
Interest, such Bearer Security shall be surrendered without the Coupon relating
to such Interest Payment Date or proposed date of payment, as the case may be
(or, if such Coupon is so surrendered with such Bearer Security, such Coupon
shall be returned to the Person so surrendering the Bearer Security), and
interest or Defaulted Interest, as the case may be, shall not be payable on such
Interest Payment Date or proposed date for payment, as the case may be, in
respect of the Registered Security issued in exchange for such Bearer Security,
but shall be payable only to the Holder of such Coupon when due in accordance
with the provisions of this Indenture.

      If provided in or pursuant to this Indenture with respect to Securities of
any series, at the option of the Holder, Registered Securities of such series
may be exchanged for Bearer Securities upon such terms and conditions as may be
provided in or pursuant to this Indenture with respect to such series.

      Whenever any Securities are surrendered for exchange as contemplated by
the immediately preceding two paragraphs, the Company shall execute, and the
Trustee shall authenticate and deliver, the Securities which the Holder making
the exchange is entitled to receive.

      Notwithstanding the foregoing, except as otherwise provided in or pursuant
to this Indenture, any global Security shall be exchangeable for definitive
Securities only if (i) the Depository is at any time unwilling, unable or
ineligible to continue as depository and a successor depository is not appointed
by the Company within 90 days of the date the Company is so informed in writing,
(ii) the Company executes and delivers to the Trustee a Company Order to the
effect that such global Security shall be so exchangeable, or (iii) an Event of
Default has occurred and is continuing with respect to the Securities. If the
beneficial owners of interests in a global Security are entitled to exchange
such interests for definitive Securities as the result of an event described in
clause (i), (ii) or (iii) of the preceding sentence, then without unnecessary
delay but in any event not later than the earliest date on which such interests
may be so exchanged, the Company shall deliver to the Trustee definitive
Securities in such form and denominations as are required by or pursuant to this
Indenture, and of the same series, containing identical terms and in aggregate
principal amount equal to the principal amount of such global Security, executed
by the Company. On or after the earliest date on which such interests may be so
exchanged, such global Security shall be surrendered from time to time by the
U.S. Depository or such other Depository as shall be specified in the Company
Order with respect thereto, and in accordance with instructions given to the
Trustee and the U.S. Depository or such other Depository, as the case may be
(which instructions shall be in writing but need not be contained in or
accompanied by an Officer's Certificate or be accompanied by an Opinion of
Counsel), as shall be specified in the Company Order with respect thereto to the
Trustee, as the Company's agent for such purpose, to be exchanged, in whole or
in part, for definitive Securities as described above without charge. The
Trustee shall authenticate and make available for delivery, in exchange for each
portion of such surrendered global Security, a like aggregate principal amount
of definitive Securities of the same series of authorized denominations and of
like tenor as the portion of such global Security to be exchanged, which (unless
such Securities


                                       34
<PAGE>

are not issuable both as Bearer Securities and as Registered Securities, in
which case the definitive Securities exchanged for the global Security shall be
issuable only in the form in which the Securities are issuable, as provided in
or pursuant to this Indenture) shall be in the form of Bearer Securities or
Registered Securities, or any combination thereof, as shall be specified by the
beneficial owner thereof, but subject to the satisfaction of any certification
or other requirements to the issuance of Bearer Securities; provided, however,
that no such exchanges may occur during a period beginning at the opening of
business 15 days before any selection of Securities of the same series to be
redeemed and ending on the relevant Redemption Date; and provided, further, that
(unless otherwise provided in or pursuant to this Indenture) no Bearer Security
delivered in exchange for a portion of a global Security shall be mailed or
otherwise delivered to any location in the United States. Promptly following any
such exchange in part, such global Security shall be returned by the Trustee to
such Depository or the U.S. Depository, as the case may be, or such other
Depository or U.S. Depository referred to above in accordance with the
instructions of the Company referred to above. If a Registered Security is
issued in exchange for any portion of a global Security after the close of
business at the Office or Agency for such Security where such exchange occurs on
or after (i) any Regular Record Date for such Security and before the opening of
business at such Office or Agency on the next succeeding Interest Payment Date,
or (ii) any Special Record Date for such Security and before the opening of
business at such Office or Agency on the related proposed date for payment of
interest or Defaulted Interest, as the case may be, interest shall not be
payable on such Interest Payment Date or proposed date for payment, as the case
may be, in respect of such Registered Security, but shall be payable on such
Interest Payment Date or proposed date for payment, as the case may be, only to
the Person to whom interest in respect of such portion of such global Security
shall be payable in accordance with the provisions of this Indenture.

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

      Every Registered Security presented or surrendered for registration of
transfer or for exchange or redemption shall (if so required by the Company or
the Security Registrar for such Security) be duly endorsed, or be accompanied by
a written instrument of transfer in form satisfactory to the Company and the
Security Registrar for such Security 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, or redemption of Securities, but the Company may require payment of a
sum sufficient to cover any tax or other governmental charge and any other
expenses (including fees and expenses of the Trustee) that may be imposed in
connection with any registration of transfer or exchange of Securities, other
than exchanges pursuant to Section 3.4, 9.5 or 11.7 not involving any transfer.

      Except as otherwise provided in or pursuant to this Indenture, the Company
shall not be required (i) to issue, register the transfer of or exchange any
Securities during a period beginning


                                       35
<PAGE>

at the opening of business 15 days before the day of mailing of a notice of
redemption of Securities of like tenor and the same series under Section 11.3
and ending at the close of business on the day of such mailing, or (ii) to
register the transfer of or exchange any Registered Security selected for
redemption in whole or in part, except in the case of any Security to be
redeemed in part, the portion thereof not to be redeemed, or (iii) to exchange
any Bearer Security selected for redemption except, to the extent provided with
respect to such Bearer Security, that such Bearer Security may be exchanged for
a Registered Security of like tenor and the same series, provided that such
Registered Security shall be immediately surrendered for redemption with written
instruction for payment consistent with the provisions of this Indenture or (iv)
to issue, register the transfer of or exchange any Security which, in accordance
with its terms, has been surrendered for repayment at the option of the Holder,
except the portion, if any, of such Security not to be so repaid.

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

      If any mutilated Security or a Security with a mutilated Coupon
appertaining to it is surrendered to the Trustee, subject to the provisions of
this Section 3.6, the Company shall execute and the Trustee shall authenticate
and deliver in exchange therefor a new Security of the same series containing
identical terms and of like principal amount and bearing a number not
contemporaneously outstanding, with Coupons appertaining thereto corresponding
to the Coupons, if any, appertaining to the surrendered Security.

      If there be delivered to the Company, the Guarantor and the Trustee (i)
evidence to their satisfaction of the destruction, loss or theft of any Security
or Coupon, and (ii) such security 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, the Guarantor or the Trustee that such Security or
Coupon has been acquired by a bona fide purchaser, the Company shall execute
and, upon the Company's request the Trustee shall authenticate and deliver, in
exchange for or in lieu of any such mutilated, destroyed, lost or stolen
Security or in exchange for the Security to which a destroyed, lost or stolen
Coupon appertains with all appurtenant Coupons not destroyed, lost or stolen, a
new Security of the same series containing identical terms and of like principal
amount and bearing a number not contemporaneously outstanding, with Coupons
appertaining thereto corresponding to the Coupons, if any, appertaining to such
destroyed, lost or stolen Security or to the Security to which such destroyed,
lost or stolen Coupon appertains.

      Notwithstanding the foregoing provisions of this Section 3.6, in case any
mutilated, destroyed, lost or stolen Security or Coupon has become or is about
to become due and payable, the Company in its discretion may, instead of issuing
a new Security, pay such Security or Coupon; provided, however, that payment of
principal of, any premium or interest on or any Additional Amounts with respect
to any Bearer Securities shall, except as otherwise provided in Section 10.2, be
payable only at an Office or Agency for such Securities located outside the
United States and, unless otherwise provided in or pursuant to this Indenture,
any interest on Bearer Securities and any Additional Amounts with respect to
such interest shall be payable only upon presentation and surrender of the
Coupons appertaining thereto.


                                       36

      Upon the issuance of any new Security under this Section 3.6, the Company
may require the payment of a sum sufficient to cover any tax or other
governmental charge that may be imposed in relation thereto and any other
expenses (including the fees and expenses of the Trustee) connected therewith.

      Every new Security, with any Coupons appertaining thereto issued pursuant
to this Section 3.6 in lieu of any destroyed, lost or stolen Security, or in
exchange for a Security to which a destroyed, lost or stolen Coupon appertains
shall constitute a separate obligation of the Company and the Guarantor, whether
or not the destroyed, lost or stolen Security and Coupons appertaining thereto
or the destroyed, lost or stolen Coupon shall be at any time enforceable by
anyone, and shall be entitled to all the benefits of this Indenture equally and
proportionately with any and all other Securities of such series and any
Coupons, if any, duly issued hereunder.

      The provisions of this Section 3.6, as amended or supplemented pursuant to
this Indenture with respect to particular Securities or generally, shall be
exclusive and shall preclude (to the extent lawful) all other rights and
remedies with respect to the replacement or payment of mutilated, destroyed,
lost or stolen Securities or Coupons.

      Section 3.7. Payment of Interest and Certain Additional Amounts; Rights to
Interest and Certain Additional Amounts Preserved.

      Unless otherwise provided in or pursuant to this Indenture, any interest
on and any Additional Amounts with respect to any Registered Security which
shall be payable, and are punctually paid or duly provided for, on any Interest
Payment Date shall be paid to the Person in whose name such Security (or one or
more Predecessor Securities) is registered as of the close of business on the
Regular Record Date for such interest.

      Unless otherwise provided in or pursuant to this Indenture, any interest
on and any Additional Amounts with respect to any Registered Security which
shall be payable, but shall not be punctually paid or duly provided for, on any
Interest Payment Date for such Registered Security (herein called "Defaulted
Interest") shall forthwith cease to be payable to the Holder thereof on the
relevant Regular Record Date by virtue of having been such Holder; and such
Defaulted Interest may be paid by the Company or the Guarantor, at its election
in each case, as provided in Clause (1) or (2) below:

           (1) The Company or the Guarantor, as the case may be, may elect to
      make payment of any Defaulted Interest to the Person in whose name such
      Registered Security (or a Predecessor Security thereof) shall be
      registered at the close of business on a Special Record Date for the
      payment of such Defaulted Interest, which shall be fixed by the Company in
      the following manner. The Company or the Guarantor, as the case may be,
      shall notify the Trustee in writing of the amount of Defaulted Interest
      proposed to be paid on such Registered Security, the Special Record Date
      therefor and the date of the proposed payment, and at the same time the
      Company or the Guarantor, as the case may be, shall deposit with the
      Trustee an amount of money equal to the aggregate amount proposed to be
      paid in respect of such Defaulted Interest or shall make arrangements


                                       37
<PAGE>

      satisfactory to the Trustee for such deposit on or prior to the date of
      the proposed payment, such money when so deposited to be held in trust for
      the benefit of the Person entitled to such Defaulted Interest as in this
      Clause provided. The Special Record Date for the payment of such Defaulted
      Interest 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
      notification to the Trustee of the proposed payment. The Trustee shall, in
      the name and at the expense of the Company or the Guarantor, cause notice
      of the proposed payment of such Defaulted Interest and the Special Record
      Date therefor to be mailed, first-class postage prepaid, to the Holder of
      such Registered Security (or a Predecessor Security thereof) at his
      address as it appears in the Security Register not less than 10 days prior
      to such Special Record Date. The Trustee may, in its discretion, in the
      name and at the expense of the Company or the Guarantor, cause a similar
      notice to be published at least once in an Authorized Newspaper of general
      circulation in the Borough of Manhattan, The City of New York, but such
      publication shall not be a conditio precedent to the establishment of such
      Special Record Date. Notice of the proposed payment of such Defaulted
      Interest and the Special Record Date therefor having been mailed as
      aforesaid, such Defaulted Interest shall be paid to the Person in whose
      name such Registered Security (or a Predecessor Security thereof) shall be
      registered at the close of business on such Special

      Record Date and shall no longer be payable pursuant to the following
clause (2).

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

      Unless otherwise provided in or pursuant to this Indenture or the
Securities of any particular series pursuant to the provisions of this
Indenture, at the option of the Company or the Guarantor, interest on Registered
Securities that bear interest may be paid by mailing a check to the address of
the Person entitled thereto as such address shall appear in the Security
Register or by transfer to an account maintained by the payee with a bank
located in the United States.

      Subject to the foregoing provisions of this Section and Section 3.5, each
Security delivered under this Indenture upon registration of transfer of or in
exchange for or in lieu of any other Security shall carry the rights to interest
accrued and unpaid, and to accrue, which were carried by such other Security.

      In the case of any Registered Security of any series that is convertible
into other securities of the Company or exchangeable for securities of the
Guarantor or another issuer, which Registered Security is converted or exchanged
after any Regular Record Date and on or prior to the next succeeding Interest
Payment Date (other than any Registered Security with respect to which the
Stated Maturity is prior to such Interest Payment Date), interest with respect


                                       38
<PAGE>

to which the Stated Maturity is on such Interest Payment Date shall be payable
on such Interest Payment Date notwithstanding such conversion or exchange, and
such interest (whether or not punctually paid or duly provided for) shall be
paid to the Person in whose name that Registered Security (or one or more
predecessor Registered Securities) is registered at the close of business on
such Regular Record Date. Except as otherwise expressly provided in the
immediately preceding sentence, in the case of any Registered Security which is
converted or exchanged, interest with respect to which the Stated Maturity is
after the date of conversion or exchange of such Registered Security shall not
be payable.

      Section 3.8. Persons Deemed Owners.

      Prior to due presentment of a Registered Security for registration of
transfer, the Company, the Guarantor, the Trustee and any agent of the Company
or the Guarantor or the Trustee may treat the Person in whose name such
Registered Security is registered in the Security Register as the owner of such
Registered Security for the purpose of receiving payment of principal of, any
premium and (subject to Sections 3.5 and 3.7) interest on and any Additional
Amounts with respect to such Registered Security and for all other purposes
whatsoever, whether or not any payment with respect to such Registered Security
shall be overdue, and none of the Company, the Guarantor, the Trustee or any
agent of the Company, the Guarantor or the Trustee shall be affected by notice
to the contrary.

      The Company, the Guarantor, the Trustee and any agent of the Company, the
Guarantor or the Trustee may treat the bearer of any Bearer Security or the
bearer of any Coupon as the absolute owner of such Security or Coupon for the
purpose of receiving payment thereof or on account thereof and for all other
purposes whatsoever, whether or not any payment with respect to such Security or
Coupon shall be overdue, and none of the Company, the Guarantor, the Trustee or
any agent of the Company, the Guarantor or the Trustee shall be affected by
notice to the contrary.

      No Holder of any beneficial interest in any global Security held on its
behalf by a Depository shall have any rights under this Indenture with respect
to such global Security, and such Depository may be treated by the Company, the
Guarantor, the Trustee, and any agent of the Company, the Guarantor or the
Trustee as the owner of such global Security for all purposes whatsoever. None
of the Company, the Guarantor, the Trustee, any Paying Agent or the Security
Registrar will have any responsibility or liability for any aspect of the
records relating to or payments made on account of beneficial ownership
interests of a global Security or for maintaining, supervising or reviewing any
records relating to such beneficial ownership interests.

      Section 3.9. Cancellation.

      All Securities and Coupons surrendered for payment, redemption,
registration of transfer, exchange or conversion or for credit against any
sinking fund payment shall, if surrendered to any Person other than the Trustee,
be delivered to the Trustee, and any such Securities and Coupons, as well as
Securities and Coupons surrendered directly to the Trustee for any such purpose,
shall be cancelled promptly by the Trustee. The Company or the Guarantor may at
any


                                       39
<PAGE>

time deliver to the Trustee for cancellation any Securities previously
authenticated and delivered hereunder which the Company or the Guarantor may
have acquired in any manner whatsoever, and all Securities so delivered shall be
cancelled promptly by the Trustee. No Securities shall be authenticated in lieu
of or in exchange for any Securities cancelled as provided in this Section,
except as expressly permitted by or pursuant to this Indenture. All cancelled
Securities and Coupons held by the Trustee shall be destroyed by the Trustee,
unless by a Company Order or Guarantor Order the Company or the Guarantor, as
the case may be, directs their return to it.

      Section 3.10. Computation of Interest.

      Except as otherwise provided in or pursuant to this Indenture or in any
Security, interest on the Securities shall be computed on the basis of a 360-day
year of twelve 30-day months.

      Section 3.11. Extension of Interest Payment Period.

      If specified as contemplated by Section 3.1 with respect to the Securities
of a particular series and subject to the terms, conditions and covenants, if
any, so specified, the Company shall have the right, at any time and from time
to time during the term of such series, to defer the payment of interest on such
Securities for such period or periods as may be specified as contemplated by
Section 3.1 (each, an "Extension Period"), during which Extension Periods the
Company shall have the right to make partial payments of interest on any
Interest Payment Date. No Extension Period shall end on a day other than an
Interest Payment Date. At the end of any such Extension Period, the Company
shall pay all interest then accrued and unpaid on the Securities (together with
Additional Interest thereon, if any, at the rate specified for the Securities of
such series to the extent permitted by applicable law). Prior to the termination
of any such Extension Period, the Company may further extend the interest
payment period, provided that no Extension Period shall exceed the period or
periods specified in such Securities or extend beyond the Stated Maturity of the
principal of such Securities. Upon termination of any Extension Period and upon
the payment of all accrued and unpaid interest and any Additional Interest then
due on any Interest Payment Date, the Company may elect to begin a new Extension
Period, subject to the above requirements. No interest shall be due and payable
during an Extension Period, except at the end thereof.

      The Company shall give the Holders of the Securities of such series and
the Trustee notice of its election to begin any such Extension Period at least
one Business Day prior to the Interest Payment Date or, with respect to the
Securities of a series issued to an ACE Trust, prior to the earlier of (i) the
date the Distributions on the Preferred Securities of such ACE Trust are payable
or (ii) the date the trustees of such ACE Trust are required to give notice to
any securities exchange or other applicable self-regulatory organization or to
holders of such Preferred Securities of the record date or the date such
Distributions are payable, but in any event not less than one Business Day prior
to such record date.

      The Trustee shall promptly give notice of the Company's election to begin
any such Extension Period to the Holders of the outstanding Securities of such
series.

      Section 3.12. Right of Set-Off.

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

      Section 3.13. Agreed Tax Treatment.

      Each Security issued hereunder shall provide that the Company, the
Guarantor and, by its acceptance of a Security or a beneficial interest therein,
the Holder of, and any Person that acquires a beneficial interest in, such
Security agree that for United States Federal, state and local tax purposes it
is intended that such Security constitute indebtedness.

      Section 3.14. Extension of Stated Maturity; Adjustment of Stated Maturity
Upon an Exchange.

      If specified as contemplated by Section 3.1 with respect to the Securities
of a particular series, the Company shall have the right to (a) change the
Stated Maturity of the principal of the Securities of such series upon the
liquidation of the applicable ACE Trust and the exchange of such Securities for
the Preferred Securities of such ACE Trust, or (b) extend the Stated Maturity of
the principal of the Securities of such series; provided that, at the time any
election to extend such Stated Maturity is made and at the time of such
extension, (i) neither the Company nor the Guarantor is in bankruptcy, otherwise
insolvent or in liquidation, (ii) neither the Company nor the Guarantor is in
default in the payment of any interest or principal or Additional Amounts on the
Securities of such series or under the Guarantee in respect thereof, as the case
may be, and no deferred interest payments thereon have accrued, (iii) the
applicable ACE Trust is not in arrears on payments of Distributions on its
Preferred Securities and no deferred Distributions thereon have accumulated,
(iv) the Securities of such series are rated not less than BBB- by Standard &
Poor's Ratings Services or Baa3 by Moody's Investors Service, Inc. or the
equivalent by any other nationally recognized statistical rating organization
and (v) the extended Stated Maturity is no later than the 49th anniversary of
the initial issuance of the Preferred Securities of the applicable ACE Trust;
provided, further, that, if the Company exercises its right to liquidate the
applicable ACE Trust and exchange the Securities of such series for the
Preferred Securities of such ACE Trust as specified in clause (a) above, any
changed Stated Maturity of the principal of the Securities of such series shall
be no earlier than the date that is five years after the initial issue date of
the Preferred Securities and no later than the date 30 years (plus an extended
term of up to an additional 19 years if the above-referenced conditions are

respect to any series of Securities specified in such Company Order or Guarantor
Order and any Coupons appertaining thereto, and the Trustee, on receipt of a
Company Order or a Guarantor Order, at the expense of the Company and the
Guarantor, shall execute proper instruments acknowledging satisfaction and

            payable, or (ii) will become due and payable at their Stated

Securities which have become due and payable) or to the Maturity thereof, as the
case may be;

      other sums payable hereunder by the Company and the Guarantor with respect

      conditions precedent herein provided for relating to the satisfaction and

Trustee shall be required to execute an instrument acknowledging satisfaction
and discharge of this Indenture only if requested to do so with respect to
Securities of such series as to which it is Trustee and if the other conditions
thereto are met.

      Notwithstanding the satisfaction and discharge of this Indenture with
respect to any series of Securities, the obligations of the Company and the

extent that the Additional Amounts payable with respect to such Securities
exceed the amount deposited in respect of such Additional Amounts pursuant to
Section 4.1(1)(b)), and with respect to any rights to convert or exchange such
Securities into securities of the Company or the Guarantor or another issuer
shall survive.

      this Section 4.2 shall not be applicable with respect to the Securities of
      such series or (ii) covenant defeasance of the Securities of or within a
      series under clause (3) of this Section 4.2 shall not be applicable with
      respect to the Securities of such series, then such provisions, together
      with the other provisions of this Section 4.2 (with such modifications
      thereto as may be specified pursuant to Section 3.1 with respect to any
      Securities), shall be applicable to such Securities and any Coupons
      appertaining thereto, and the Company may at its option by Board
      Resolution, at any time, with respect to such Securities and any Coupons
      appertaining thereto, elect to have Section 4.2(2) or Section 4.2(3) be
      applied to such Outstanding Securities and any Coupons appertaining
      thereto upon compliance with the conditions set forth below in this
      Section 4.2.


                                       43
<PAGE>

            (2) Upon the Company's exercise of the above option applicable to
      this Section 4.2(2) with respect to any Securities of or within a series,
      the Company and the Guarantor shall be deemed to have been discharged from
      its obligations with respect to such Outstanding Securities and any
      Coupons appertaining thereto and under the Guarantee in respect thereof,
      respectively, on the date the conditions set forth in clause (4) of this
      Section 4.2 are satisfied (hereinafter, "defeasance"). For this purpose,
      such defeasance means that the Company or the Guarantor shall be deemed to
      have paid and discharged the entire Indebtedness represented by such
      Outstanding Securities and any Coupons appertaining thereto, and under the
      Guarantee in respect thereof, which shall thereafter be deemed to be
      "Outstanding" only for the purposes of clause (5) of this Section 4.2 and
      the other Sections of this Indenture referred to in clauses (i) and (ii)
      below, and to have satisfied all of its other obligations under such
      Securities and any Coupons appertaining thereto, and under the Guarantee
      in respect thereof, and this Indenture insofar as such Securities and any
      Coupons appertaining thereto, and the Guarantee in respect thereof, are
      concerned (and the Trustee, at the expense of the Company and the
      Guarantor, shall execute proper instruments acknowledging the same),
      except for the following which shall survive until otherwise terminated or
      discharged hereunder: (i) the rights of Holders of such Outstanding
      Securities and any Coupons appertaining thereto to receive, solely from
      the trust fund described in clause (4) of this Section 4.2 and as more
      fully set forth in such clause, payments in respect of the principal of
      (and premium, if any) and interest (including any Additional Interest), if
      any, on, and Additional Amounts, if any, with respect to, such Securities
      and any Coupons appertaining thereto when such payments are due, and any
      rights of such Holder to convert such Securities into other securities of
      the Company or exchange such Securities for securities of the Guarantor or
      another issuer, (ii) the obligations of the Company, the Guarantor and the
      Trustee with respect to such Securities under Sections 3.5, 3.6, 10.2 and
      10.3 and with respect to the payment of Additional Amounts, if any, on
      such Securities as contemplated by Sections 10.4 and 17.2 (but only to the
      extent that the Additional Amounts payable with respect to such Securities
      exceed the amount deposited in respect of such Additional Amounts pursuant
      to Section 4.2(4)(a) below), and with respect to any rights to convert
      such Securities into other securities of the Company or exchange such
      Securities for securities of the Guarantor or another issuer, (iii) the
      rights, powers, trusts, duties and immunities of the Trustee hereunder and
      (iv) this Section 4.2. The ompany may exercise its option under this
      Section 4.2(2) notwithstanding the prior exercise of its option under
      clause (3) of this Section 4.2 with respect to such Securities and any
      Coupons appertaining thereto.

           (3) Upon the Company's exercise of the option to have this Section
      4.2(3) apply with respect to any Securities of or within a series, the
      Company and the Guarantor shall be released from their obligations under
      any covenant applicable to such Securities specified pursuant to Section
      3.1(20), with respect to such Outstanding Securities and any Coupons
      appertaining thereto, and the Guarantee in respect thereof, on and after
      the date the conditions set forth in clause (4) of this Section 4.2 are
      satisfied (hereinafter, "covenant defeasance"), and such Securities and
      any Coupons appertaining thereto shall


                                       44
<PAGE>

      thereafter be deemed to be not "Outstanding" for the purposes of any
      direction, waiver, consent or declaration or Act of Holders (and the
      consequences of any thereof) in connection with any such covenant, but
      shall continue to be deemed "Outstanding" for all other purposes
      hereunder. For this purpose, such covenant defeasance means that, with
      respect to such Outstanding Securities and any Coupons appertaining
      thereto, the Company and the Guarantor may omit to comply with, and shall
      have no liability in respect of, any term, condition or limitation set
      forth in any such Section or such other covenant, whether directly or

      Section or such other covenant or by reason of reference in any such
      Section or such other covenant to any other provision herein or in any
      other document and such omission to comply shall not constitute a default
      or an Event of Default under Section 5.1(4) or 5.1(9) or otherwise, as the
      case may be, but, except as specified above, the remainder of this
      Indenture and such Securities and Coupons appertaining thereto and the
      Guarantee in respect thereof shall be unaffected thereby.

           (4) The following shall be the conditions to application of clause

                 (a) The Company or the Guarantor shall irrevocably have
            deposited or caused to be deposited with the Trustee (or another
            trustee satisfying the requirements of Section 6.7 who shall agree

            or (3) a combination thereof, in any case, in an amount, sufficient,
            without consideration of any reinvestment of such principal and
            interest, in the opinion of a nationally recognized firm of
            independent public accountants expressed in a written certification
            thereof delivered to the Trustee, to pay and discharge, and which
            shall be applied by the Trustee (or other qualifying trustee) to pay
            and discharge, (y) the principal of (and premium, if any) and
            interest (including any Additional Interest), if any, on such

            Stated Maturity of such principal or installment of principal or
            premium or interest and (z) any mandatory sinking fund payments or
            analogous payments applicable to

            Coupons appertaining thereto.

                  (b) Such defeasance or covenant defeasance shall not result in
            a breach or violation of, or constitute a default under, this
            Indenture or any other material agreement or instrument to which the
            Company or the Guarantor is a party or by which either of them is
            bound.

                  (c) No Event of Default or event which with notice or lapse of
            time or both would become an Event of Default with respect to such
            Securities and any Coupons appertaining thereto shall have occurred
            and be continuing on the date of such deposit and, with respect to
            defeasance only, at any time during the period ending on the 123rd
            day after the date of such deposit (it being understood that this
            condition shall not be deemed satisfied until the expiration of such
            period).

                  (d) In the case of an election under clause (2) of this
            Section 4.2, the Company or the Guarantor shall have delivered to
            the Trustee an Opinion of Counsel stating that (i) the Company or
            the Guarantor has received from the Internal Revenue Service a
            letter ruling, or there has been published by the Internal Revenue
            Service a Revenue Ruling, or (ii) since the date of execution of
            this Indenture, there has been a change in the applicable Federal
            income tax law, in either case to the effect that, and based thereon
            such opinion shall confirm that, the Holders of such Outstanding
            Securities and any Coupons appertaining thereto will not recognize
            income, gain or loss for Federal income tax purposes as a result of
            such defeasance and will be subject to Federal income tax on the
            same amounts, in the same manner and at the same times as would have
            been the case if such defeasance had not occurred.

            Section 4.2, the Company or the Guarantor shall have delivered to
            the Trustee an Opinion of Counsel to the effect that the Holders of
            such Outstanding Securities and any Coupons appertaining thereto
            will not recognize income, gain or loss for Federal income tax
            purposes as a result of such covenant defeasance and will be subject
            to Federal income tax on the same amounts, in the same manner and at
            the same times as would have been the case if such covenant
            defeasance had not occurred.

                  (f) The Company or the Guarantor shall have delivered to the
            Trustee an Opinion of Counsel to the effect that, after the 123rd
            day after the date of deposit, all money and Government Obligations
            (or other property as may be provided pursuant to Section 3.1)
            (including the proceeds thereof) deposited or caused to be deposited
            with the Trustee (or other qualifying trustee) pursuant to this
            clause (4) to be held in trust will not be subject to any case or
            proceeding (whether voluntary or involuntary) in respect of the
            Company or the Guarantor under any Federal or State bankruptcy,
            insolvency, reorganization or other similar


                                       46

            the Guarantor issued in connection therewith.

                 (g) The Company and the Guarantor shall have delivered to the
            Trustee an Officer's Certificate and a Guarantor's Officer's
            Certificate and the Company or the Guarantor shall have delivered to
            the Trustee an Opinion of Counsel, each stating that all conditions
            precedent to the defeasance or covenant defeasance under clause (2)
            or (3) of this Section 4.2 (as the case may be) have been complied
            with.

                 (h) Notwithstanding any other provisions of this Section
            4.2(4), such defeasance or covenant defeasance shall be effected in
            compliance with any additional or substitute terms, conditions or
            limitations which may be imposed on the Company or the Guarantor in
            connection therewith pursuant to Section 3.1.

            (5) Unless otherwise specified in or pursuant to this Indenture or
      any Security, if, after a deposit referred to in Section 4.2(4)(a) has

      was made is entitled to, and does, elect pursuant to Section 3.1 or the
      terms of such Security to receive payment in a Currency other than that in
      which the deposit pursuant to Section 4.2(4)(a) has been made in respect
      of such Security, or (b) a Conversion Event occurs in respect of the
      Foreign Currency in which the deposit pursuant to Section 4.2(4)(a) has
      been made, the indebtedness represented by such Security and any Coupons
      appertaining thereto shall be deemed to have been, and will be, fully
      discharged and satisfied through the payment of the principal of (and
      premium, if any), and interest (including any Additional Interest), if
      any, on, and Additional Amounts, if any, with respect to, such Security as
      the same becomes due out of the proceeds yielded by converting (from time
      to time as specified below in the case of any such election) the amount or
      other property deposited in respect of such Security into the Currency in
      which such Security becomes payable as a result of such election or
      Conversion Event based on (x) in the case of payments made pursuant to
      clause (a) above, the applicable market exchange rate for such Currency in
      effect on the second Business Day prior to each payment date, or (y) with
      respect to a Conversion Event, the applicable market exchange rate for
      such Foreign Currency in effect (as nearly as feasible) at the time of the
      Conversion Event.

      The Company and the Guarantor (without duplication) shall pay and
indemnify the Trustee (or other qualifying trustee, collectively for purposes of
this Section 4.2(5) and Section 4.3, the "Trustee") against any tax, fee or
other charge, imposed on or assessed against the Government Obligations
deposited pursuant to this Section 4.2 or the principal or interest received in
respect thereof other than any such tax, fee or other charge which by law is for
the account of the Holders of such Outstanding Securities and any Coupons
appertaining thereto.

      Anything in this Section 4.2 to the contrary notwithstanding, the Trustee
shall deliver or pay to the Company from time to time upon Company Request, or
the Guarantor upon Guarantor Request, as the case may be, any money or
Government Obligations (or other property and any


                                       47
<PAGE>

proceeds therefrom) held by it as provided in clause (4) of this Section 4.2
which, in the opinion of a nationally recognized firm of independent public
accountants expressed in a written certification thereof delivered to the
Trustee, are in excess of the amount thereof which would then be required to be
deposited to effect a defeasance or covenant defeasance, as applicable, in
accordance with this Section 4.2.

      Section 4.3. Application of Trust Money.

      Subject to the provisions of the last paragraph of Section 10.3, all money
and Government Obligations (or other property as may be provided pursuant to
Section 3.1) (including the proceeds thereof) deposited with the Trustee
pursuant to Section 4.1 or 4.2 in respect of any Outstanding Securities of any
series and any Coupons appertaining thereto shall be held in trust and applied
by the Trustee, in accordance with the provisions of such Securities and any
Coupons appertaining thereto and this Indenture, to the payment, either directly
or through any Paying Agent (including the Company acting as its own Paying
Agent or the Guarantor acting as Paying Agent) as the Trustee may determine, to
the Holders of such Securities and any Coupons appertaining thereto of all sums
due and to become due thereon in respect of principal (and premium, if any) and
interest (including any Additional Interest) and Additional Amounts, if any; but
such money and Government Obligations need not be segregated from other funds
except to the extent required by law.

      If an Event of Default with respect to Securities of any series at the
time Outstanding (other than an Event of Default specified in clause (7) or (8)
of Section 5.1) occurs and is continuing, then the Trustee or the Holders of not
less than 25% in principal amount of the Outstanding Securities of such series
may declare the principal of all the Securities of such series, or such lesser
amount as may be provided for in the Securities of such series, to be due


                                       50
<PAGE>

and payable immediately, by a notice in writing to the Company and the Guarantor
(and to the Trustee if given by the Holders), and upon any such declaration such
principal or such lesser amount shall become immediately due and payable;
provided that, in the case of Securities of a series issued to an ACE Trust, if,
upon an Event of Default, the Trustee or the Holders of not less than 25% in
principal amount of the Outstanding Securities of such series fail to declare
the principal of all the Securities of such series, or such lesser amount as may
be provided for in the Securities of such series, to be immediately due and
payable, the holders of at least 25% in liquidation amount of the Preferred
Securities of such ACE Trust then outstanding shall have such right by a notice
in writing to the Company, the Guarantor, the Trustee and the Property Trustee;
and upon any such declaration such principal or such lesser amount and all
accrued and unpaid interest (including any Additional Interest) thereon shall
become immediately due and payable, provided that the payment of principal and
interest and all other amounts due with respect to such Securities shall remain
subordinated to the extent provided in Article 16.

      If an Event of Default specified in clause (7) or (8) of Section 5.1
occurs, all unpaid principal of and accrued interest (including any Additional
Interest) on the Outstanding Securities of that series (or such lesser amount as
may be provided for in the Securities of such series) shall ipso facto become
and be immediately due and payable without any declaration or other act on the
part of the Trustee or any Holder of any Security of that series.

      At any time after a declaration of acceleration with respect to the
Securities of any series has been made and before a judgment or decree for
payment of the money due has been obtained by the Trustee as hereinafter in this
Article provided, the Holders of not less than a majority in principal amount of
the Outstanding Securities of such series (subject to, in the case of any series
of Securities held as assets of an ACE Trust, such consent of the holders of the
Preferred Securities and the Common Securities of such ACE Trust as may be
required under the Trust Agreement of such ACE Trust), by written notice to the
Company, the Guarantor and the Trustee, may rescind and annul such declaration
and its consequences if

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

                 (a) all overdue installments of any interest (including any
            Additional Interest) on and Additional Amounts with respect to all
            Securities of such series and any Coupon appertaining thereto,

                 (b) the principal of and any premium on any Securities of
            such series which have become due otherwise than by such declaration
            of acceleration and interest thereon and any Additional Amounts with
            respect thereto at the rate or rates borne by or provided for in
            such Securities,

                 (c) to the extent that payment of such interest or Additional
            Amounts is lawful, interest upon overdue installments of any
            interest and Additional Amounts at the rate or rates borne by or
            provided for in such Securities, and


                                       51
<PAGE>

                 (d) all sums paid or advanced by the Trustee hereunder and
            the reasonable compensation, expenses, disbursements and advances of
            the Trustee, its agents and counsel and all other amounts due the
            Trustee under Section 6.6; and

           (2) all Events of Default with respect to Securities of such
      series, other than the non-payment of the principal of, any premium and
      interest on, and any Additional Amounts with respect to Securities of such
      series which shall have become due solely by such declaration of
      acceleration, shall have been cured or waived as provided in Section 5.13.

      In the case of Securities of a series issued to an ACE Trust, should the
Holders of such Securities fail to rescind and annul such declaration and its
consequences, the holders of a majority in liquidation amount of the Preferred
Securities of such ACE Trust then outstanding shall have such right by written
notice to the Company, the Guarantor, the Trustee and the Property Trustee,
subject to satisfaction of the conditions set forth in clauses (1) and (2) above
of this Section 5.2.

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

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

      The Company and the Guarantor each covenants, in each case, that if

            (1) default is made in the payment of any installment of interest
      (including any Additional Interest) on or any Additional Amounts with
      respect to any Security or any Coupon appertaining thereto when such
      interest or Additional Amounts shall have become due and payable and such
      default continues for a period of 30 days, or

            (2) default is made in the payment of the principal of or any
      premium on any Security or any Additional Amounts with respect thereto at
      their Maturity,

the Company or the Guarantor, as the case may be, shall, upon demand of the
Trustee, pay to the Trustee, for the benefit of the Holders of such Securities
and any Coupons appertaining thereto, the whole amount of money then due and
payable with respect to such Securities and any Coupons appertaining thereto,
with interest (including any Additional Interest) upon the overdue principal,
any premium and (to the extent that payment of such interest shall be legally
enforceable and, if the Securities are held by an ACE Trust, without duplication
of any other amounts paid to such ACE Trust in respect thereof) upon any overdue
installments of interest and Additional Amounts at the rate or rates borne by or
provided for in such Securities, and, in addition thereto, such further amount
of money 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 and all other amounts due to the Trustee
under Section 6.6.

      If the Company or the Guarantor fails to pay the money it is required to
pay the Trustee pursuant to the preceding paragraph forthwith upon the demand of
the Trustee, the Trustee, in its own name and as trustee of an express trust,
may institute a judicial proceeding for the collection of the money so due and
unpaid, and may prosecute such proceeding to judgment or final decree, and may
enforce the same against the Company or the Guarantor or any other obligor upon
such Securities and any Coupons appertaining thereto and collect the monies
adjudged or decreed to be payable in the manner provided by law out of the
property of the Company or the Guarantor or any other obligor upon such
Securities and any Coupons appertaining thereto, wherever situated.

      If an Event of Default with respect to Securities of any series occurs and
is continuing, the Trustee may in its discretion proceed to protect and enforce
its rights and the rights of the Holders of Securities of such series and any
Coupons appertaining thereto 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 such Securities or in aid of the exercise of any power granted
herein or therein, or to enforce any other proper remedy.

      Section 5.4. Trustee May File Proofs of Claim.

      In case of the pendency of any receivership, insolvency, liquidation,
bankruptcy, reorganization, arrangement, adjustment, composition or other
judicial proceeding relative to the Company, the Guarantor or any other obligor
upon the Securities of any series or the property of the Company, the Guarantor
or such other obligor or their creditors, the Trustee (irrespective of whether
the principal of the Securities shall then be due and payable as therein
expressed or by declaration or otherwise and irrespective of whether the Trustee
shall have made any demand on the Company or the Guarantor for the payment of
any overdue principal, premium, interest (including any Additional Interest) or
Additional Amounts) shall be entitled and empowered, by intervention in such
proceeding or otherwise,

           (1) to file and prove a claim for the whole amount, or such lesser
      amount as may be provided for in the Securities of any applicable series,
      of the principal and any premium, interest (including any Additional
      Interest) and Additional Amounts owing and unpaid in respect of the
      Securities and any Coupons appertaining thereto and to file such other
      papers or documents as may be necessary or advisable in order to have the
      claims of the Trustee (including any claim for the reasonable
      compensation, expenses, disbursements and advances of the Trustee, its
      agents or counsel) and of the Holders of Securities or any Coupons
      appertaining thereto allowed in such judicial proceeding, and

            (2) to collect and receive any monies 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 of Securities or any Coupons to make such payments to the Trustee
and, in the event that the Trustee shall consent to the


                                       53
<PAGE>

making of such payments directly to the Holders of Securities or any Coupons, to
pay to the Trustee any amount due to 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 6.6.

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

      Section 5.5. Trustee May Enforce Claims without Possession of Securities
or Coupons.

      All rights of action and claims under this Indenture or any of the
Securities or Coupons may be prosecuted and enforced by the Trustee without the
possession of any of the Securities or Coupons or the production thereof in any
proceeding relating thereto, and any such proceeding instituted by the Trustee
shall be brought in its own name as trustee of an express trust, and any
recovery or judgment, after provision for the payment of the reasonable
compensation, expenses, disbursements and advances of the Trustee, its agents
and counsel, shall be for the ratable benefit of each and every Holder of the
Securities or Coupons in respect of which such judgment has been recovered.

      Any money collected by the Trustee pursuant to this Article shall be
applied in the following order, at the date or dates fixed by the Trustee and,
in case of the distribution of such money on account of principal, or any
premium, interest (including any Additional Interest) or Additional Amounts,

      predecessor Trustee under Section 6.6;

            SECOND: To the payment of the amounts then due and unpaid upon the
      Securities and any Coupons for principal and any premium, interest and
      Additional Amounts in respect of which or for the benefit of which such
      money has been collected, ratably, without preference or priority of any
      kind, according to the aggregate amounts due and payable on such
      Securities and Coupons for principal and any premium, interest (including

      Section 5.7. Limitations on Suits.

      No Holder of any Security of any series or any Coupons appertaining
thereto shall have any right to institute any proceeding, judicial or otherwise,
with respect to this Indenture, or for the appointment of a receiver or trustee,
or for any other remedy hereunder, unless

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

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

           (3) such Holder or Holders have offered to the Trustee such
      indemnity as is reasonably satisfactory to it against the costs, expenses
      and liabilities to be incurred in compliance with such request;

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

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

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

      Section 5.8. Unconditional Right of Holders to Receive Principal and any
Premium, Interest and Additional Amounts.

      Notwithstanding any other provision in this Indenture, the Holder of any
Security or Coupon shall have the right, which is absolute and unconditional, to
receive payment of the principal of, any premium and (subject to Sections 3.5,
3.7 and 3.11) interest (including any Additional Interest) on, and any
Additional Amounts with respect to such Security or payment of such Coupon, as
the case may be, on the respective Stated Maturity or Maturities therefor
specified in such Security or Coupon (or, in the case of redemption, on the
Redemption Date or, in the case of repayment at the option of such Holder if
provided in or pursuant to this Indenture, on the date such repayment is due)
and to institute suit for the enforcement of any such payment, and such right
shall not be impaired without the consent of such Holder. In the case of
Securities of a series issued to an ACE Trust, any holder of Preferred
Securities issued by such ACE Trust shall have the right, upon the occurrence of
an Event of Default described in Section 5.1(1) or


                                       55
<PAGE>

5.1(2) hereof, to institute directly a proceeding against the Company or the
Guarantor, as the case may be, for enforcement of payment to such holder of
principal of, and any premium and (subject to Sections 3.5, 3.7 and 3.11)
interest (including any Additional Interest) on, and Additional Amounts with
respect to, such Securities having a principal amount equal to the liquidation
amount of such Preferred Securities held by such holder (a "Direct Action").
Notwithstanding any payments made to a holder of Preferred Securities by the
Company or the Guarantor in connection with a Direct Action, the Company and the
Guarantor shall remain obligated to pay the principal of and premium, if any, or
interest on and Additional Amounts, if any, with respect to the related
Securities, and the Company or the Guarantor 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 or the
Guarantor, as the case may be, to such holder in any Direct Action.

      Section 5.9. Restoration of Rights and Remedies.

      If the Trustee or any Holder of a Security or a Coupon has, or the holders
of Preferred Securities have, 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, to
such Holder or to the holders of such Preferred Securities, then and in every
such case the Company, the Guarantor, the Trustee and each such Holder or the
holders of such Preferred Securities shall, subject to any determination in such
proceeding, be restored severally and respectively to their former positions
hereunder, and thereafter all rights and remedies of the Trustee and each such
Holder or the holders of such Preferred Securities shall continue as though no
such proceeding had been instituted.

      Section 5.10. Rights and Remedies Cumulative.

      Except as otherwise provided with respect to the replacement or payment of
mutilated, destroyed, lost or stolen Securities or Coupons in the last paragraph
of Section 3.6, no right or remedy herein conferred upon or reserved to the
Trustee, to each and every Holder of a Security or a Coupon or to the holders of
Preferred Securities is intended to be exclusive of any other right or remedy,
and every right and remedy, to the extent permitted by law, shall 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, to the extent
permitted by law, prevent the concurrent assertion or employment of any other
appropriate right or remedy.

      Section 5.11. Delay or Omission Not Waiver.

      No delay or omission of the Trustee or of any Holder of any Security or
Coupon or of the holders of Preferred Securities to exercise any right or remedy
accruing upon any Event of Default shall impair any such right or remedy or
constitute a waiver of any such Event of Default or an acquiescence therein.
Every right and remedy given by this Article or by law to the Trustee or to any
Holder of a Security or a Coupon or to the holders of Preferred Securities may


                                       56
<PAGE>

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

      Section 5.12. Control by Holders of Securities.

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

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

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

            (3) such direction is not unduly prejudicial to the rights of the
      other Holders of Securities of such series not joining in such action.

      Section 5.13. Waiver of Past Defaults.

      The Holders of not less than a majority in principal amount of the
Outstanding Securities of any series on behalf of the Holders of all the
Securities of such series and any Coupons appertaining thereto and, in the case
of any Securities issued to an ACE Trust, the holders of not less than a
majority in liquidation amount of the Preferred Securities issued by such ACE
Trust then outstanding, may waive any past default hereunder with respect to
such series and its consequences, except a default

            (1) in the payment of the principal of, any premium or interest
      (including any Additional Interest) on, or any Additional Amounts with
      respect to, any Security of such series or any Coupons appertaining
      thereto, or

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

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

      Section 5.14. Waiver of Usury, Stay or Extension Laws.

      The Company and the Guarantor each covenants that (to the extent that it
may lawfully do so) it will not at any time insist upon, or plead, or in any
manner whatsoever claim or take the benefit or advantage of, any usury, stay or
extension law wherever enacted, now or at any time


                                       57
<PAGE>

hereafter in force, which may affect the covenants or the performance of this
Indenture; and the Company and the Guarantor each expressly waives (to the
extent that it may lawfully do so) 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 5.15. Undertaking for Costs

      All parties to this Indenture agree, and each Holder of any Security by
his acceptance thereof shall be deemed to have agreed, that any court may in its
discretion require, in any suit for the enforcement of any right or remedy under
this Indenture, or in any suit against the Trustee for any action taken or
omitted by it as Trustee, the filing by any party litigant in such suit of any
undertaking to pay the costs of such suit, and that such court may in its
discretion assess reasonable costs, including reasonable attorneys' fees,
against any party litigant in such suit having due regard to the merits and good
faith of the claims or defenses made by such party litigant; but the provisions
of this Section 5.15 shall not apply to any suit instituted by the Trustee, to
any suit instituted by any Holder, or group of Holders, holding in the aggregate
more than 10% in principal amount of Outstanding Securities of any series or, if
a series of Securities is held by an ACE Trust, the holders of more than 10% in
liquidation amount of the Preferred Securities of that ACE Trust then
outstanding, or to any suit instituted by any Holder or any holder of Preferred
Securities for the enforcement of the payment of the principal of (or premium,
if any) or interest (including any Additional Interest), if any, on or
Additional Amounts, if any, with respect to any Security on or after the
respective Stated Maturities expressed in such Security (or, in the case of
redemption, on or after the Redemption Date, and, in the case of repayment, on
or after the date for repayment) or for the enforcement of the right, if any, to
convert or exchange any Security into other securities in accordance with its
terms.

      and, if the Trustee shall determine to make such further inquiry or
      investigation, it shall be entitled to examine, during business hours and
      upon reasonable notice, the books, records and premises of the Company and
      the Guarantor, personally or by agent or attorney;

            (7) the Trustee may execute any of the trusts or powers hereunder or
      perform any duties hereunder either directly or by or through agents or

      proceeding for any remedy available to the Trustee, or exercising any
      trust or power conferred upon the Trustee, under this Indenture or any

principal of (or premium, if any), or interest (including any Additional
Interest), if any, on, or Additional Amounts or any sinking fund or purchase
fund installment with respect to, any Security of such series, the Trustee shall
be protected in withholding such notice if and so long as the board of
directors, the executive committee or a trust committee of directors and/or
Responsible Officers of the Trustee in good faith determine that the withholding
of such notice is in the best interest of the Holders of Securities and Coupons
of such series; and provided, further, that in the case of any default of the
character specified in Section 5.1(5) with respect to Securities of such series,
no such notice to Holders shall be given until at least 30 days after the
occurrence thereof. For the purpose of this Section, the term "default" means
any event which is, or after notice or lapse of time or both would become, an
Event of Default with respect to Securities of such series.

      Section 6.3. Not Responsible for Recitals or Issuance of Securities.

certificate of authentication, and in any Coupons shall be taken as the
statements of the Company or the Guarantor, as the case may be, and neither the
Trustee nor any Authenticating Agent assumes any responsibility for their
correctness. The Trustee makes no representations as to the validity or
sufficiency of this Indenture or of the Securities or the Coupons, except that

      The Trustee, any Authenticating Agent, any Paying Agent, any Security
Registrar or any other Person that may be an agent of the Trustee or the
Guarantor or the Company, in its individual or any other capacity, may become
the owner or pledgee of Securities or Coupons


                                       60
<PAGE>

and, subject to Sections 310(b) and 311 of the Trust Indenture Act, may
otherwise deal with the Company or the Guarantor with the same rights it would
have if it were not the Trustee, Authenticating Agent, Paying Agent, Security
Registrar or such other Person.

      The Company and the Guarantor (without duplication) each agree:

           (1) to pay to the Trustee from time to time reasonable compensation
      for all services rendered by the Trustee hereunder (which compensation
      shall not be limited by any provision of law in regard to the compensation
      of a trustee of an express trust);

           (2) except as otherwise expressly provided herein, to reimburse the
      Trustee upon its request for all reasonable expenses, disbursements and
      advances incurred or made by the Trustee in accordance with any provision
      of this Indenture or arising out of or in connection with the acceptance
      or administration of the trust or trusts hereunder (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 the Trustee's negligence or bad faith; and

           (3) to indemnify the Trustee and its agents, officers, directors
      and employees for, and to hold them harmless against, any loss, liability
      or expense incurred without negligence or bad faith on their part, arising
      out of or in connection with the acceptance or administration of the trust
      or trusts hereunder, including the costs and expenses of defending
      themselves against any claim or liability in connection with the exercise
      or performance of any of their powers or duties hereunder, except to the
      extent that any such loss, liability or expense was due to the Trustee's
      negligence or bad faith.

      As security for the performance of the obligations of the Company and the
Guarantor under this Section, the Trustee shall have a lien prior to the
Securities of any series upon all property and funds held or collected by the
Trustee as such, except funds held in trust for the payment of principal of, and
premium or interest (including any Additional Interest) on or any Additional
Amounts with respect to Securities or any Coupons appertaining thereto.

      To the extent permitted by law, any compensation or expense incurred by
the Trustee after a default specified in or pursuant to Section 5.1 is intended
to constitute an expense of administration under any then applicable bankruptcy
or insolvency law. "Trustee" for purposes

bad faith of any Trustee shall not affect the rights of any other Trustee under
this Section 6.6.

      The provisions of this Section 6.6 shall survive the satisfaction and

and shall apply with equal force and effect to the Trustee in its capacity as
Authenticating Agent, Paying Agent or Security Registrar.

      Section 6.7. Corporate Trustee Required; Eligibility.

      There shall at all times be a Trustee hereunder that is a Corporation
organized and doing business under the laws of the United States of America, any
state thereof or the District of Columbia, that is eligible under Section

           (2) The Trustee may resign at any time with respect to the

                  (a) the Trustee shall fail to comply with the obligations
            imposed upon it under Section 310(b) of the Trust Indenture Act with
            respect to Securities of any series after written request therefor
            by the Company, the Guarantor or any Holder of a Security of such
            series who has been a bona fide Holder of a Security of such series
            for at least six months, or

<PAGE>

                  (b) the Trustee shall cease to be eligible under Section 6.7
            and shall fail to resign after written request therefor by the
            Company, the Guarantor or any such Holder, or

                  (c) the Trustee shall become incapable of acting or shall be
            adjudged a bankrupt or insolvent or a receiver of the Trustee or of
            its property shall be appointed or any public officer shall take
            charge or control of the Trustee or of its property or affairs for
            the purpose of rehabilitation, conservation or liquidation, then, in

            Resolution, or the Guarantor, by or pursuant to a Guarantor's Board
            Resolution, may remove the Trustee with respect to all Securities or
            the Securities of such series, or (ii) subject to Section 315(e) of
            the Trust Indenture Act, any Holder of a Security who has been a
            bona fide Holder of a Security of such series for at least six

            Trustee with respect to all Securities of such series and the
            appointment of a successor Trustee or Trustees.

           (5) If the Trustee shall resign, be removed or become incapable of
      acting, or if a vacancy shall occur in the office of Trustee for any
      cause, with respect to the Securities of one or more series, the Company,
      by or pursuant to a Board Resolution, and the Guarantor, by or pursuant to
      a Guarantor's Board Resolution, shall promptly appoint a successor Trustee
      or Trustees with respect to the Securities of such series (it being
      understood that any such successor Trustee may be appointed with respect
      to the Securities of one or more or all of such series and that at any
      time there shall be only one Trustee with respect to the Securities of any
      particular series) and shall comply with the applicable requirements of
      Section 6.9. If, within one year after such resignation, removal or
      incapacity, or the occurrence of such vacancy, a successor Trustee with
      respect to the Securities of any series shall be appointed by Act of the
      Holders of a majority in principal amount of the Outstanding Securities of
      such series delivered to the Company, the Guarantor and the retiring
      Trustee, the successor Trustee so appointed shall, forthwith upon its
      acceptance of such appointment in accordance with the applicable
      requirements of Section 6.9, become the successor Trustee with respect to
      the Securities of such series and to that extent supersede the successor
      Trustee appointed by the Company and the Guarantor. If no successor
      Trustee with respect to the Securities of any series shall have been so
      appointed by the Company and the Guarantor or the Holders of Securities
      and accepted appointment in the manner required by Section 6.9, any Holder
      of a Security who has been a bona fide Holder of a Security of such series
      for at least six months may, on behalf of himself and all others similarly
      situated, petition any court of competent jurisdiction for the appointment
      of a successor Trustee with respect to the Securities of such series.

            (6) The Company shall give notice of each resignation and each
      removal of the Trustee with respect to the Securities of any series and
      each appointment of a successor Trustee with respect to the Securities of
      any series by mailing written notice of


                                       63
<PAGE>

      such event by first-class mail, postage prepaid, to the Holders of
      Registered Securities, if any, of such series as their names and addresses
      appear in the Security Register and, if Securities of such series are
      issued as Bearer Securities, by publishing notice of such event once in an
      Authorized Newspaper in each Place of Payment located outside the United
      States. Each notice shall include the name of the successor Trustee with
      respect to the Securities of such series and the address of its Corporate
      Trust Office.

           (7) In no event shall any retiring Trustee be liable for the acts
      or omissions of any successor Trustee hereunder.

      Section 6.9. Acceptance of Appointment by Successor.

           (1) Upon the appointment hereunder of any successor Trustee with
      respect to all Securities, such successor Trustee so appointed shall
      execute, acknowledge and deliver to the Company, the Guarantor and the
      retiring Trustee an instrument accepting such appointment, and thereupon
      the resignation or removal of the retiring Trustee shall become effective
      and such successor Trustee, without any further act, deed or conveyance,
      shall become vested with all the rights, powers, trusts and duties
      hereunder of the retiring Trustee; but, on the request of the Company, the
      Guarantor or such successor Trustee, such retiring Trustee, upon payment
      of its charges, shall execute and deliver an instrument transferring to
      such successor Trustee all the rights, powers and trusts of the retiring
      Trustee and, subject to Section 10.3, shall duly assign, transfer and
      deliver to such successor Trustee all property and money held by such
      retiring Trustee hereunder, subject nevertheless to its claim, if any,
      provided for in Section 6.6.

           (2) Upon the appointment hereunder of any successor Trustee with
      respect to the Securities of one or more (but not all) series, the
      Company, the Guarantor, the retiring Trustee and such successor Trustee
      shall execute and deliver an indenture supplemental hereto wherein each
      successor Trustee shall accept such appointment and which (1) shall
      contain such provisions as shall be necessary or desirable to transfer and
      confirm to, and to vest in, such successor Trustee all the rights, powers,

      in the retiring Trustee, and (3) shall add to or change any of the
      provisions of this Indenture as shall be necessary to provide for or
      facilitate the administration of the trusts hereunder by more than one
      Trustee, it being understood that nothing herein or in such supplemental
      indenture shall constitute such Trustees co-trustees of the same trust,
      that each such Trustee shall be trustee of a trust or trusts hereunder
      separate and apart from any trust or trusts hereunder administered by any
      other such Trustee and that no Trustee shall be responsible for any notice
      given to, or received by, or any act or failure to act on the part of any
      other Trustee hereunder, and, upon the

      removal of the retiring Trustee shall become effective to the extent
      provided therein, such retiring Trustee shall have no further
      responsibility for the exercise of rights and powers or for the
      performance of the duties and obligations vested in the Trustee under this
      Indenture ith respect to the Securities of that or those series to which
      the appointment of such successor Trustee relates other than as
      hereinafter expressly set forth, and such successor Trustee, without any
      further act, deed or conveyance, shall become vested with all the rights,
      powers, trusts and duties of the retiring Trustee with respect to the
      Securities of that or those series to which the appointment of such
      successor Trustee relates; but, on request of the Company, the Guarantor
      or such successor Trustee, such retiring Trustee, upon payment of its
      charges with respect to the Securities of that or those series to which
      the appointment of such successor Trustee relates and subject to Section
      10.3 shall duly assign, transfer and deliver to such successor Trustee, to
      the extent contemplated by such supplemental indenture, the property and
      money held by such retiring Trustee hereunder with respect to the
      Securities of that or those series to which the appointment of such
      successor Trustee relates, subject to its claim, if any, provided for in
      Section 6.6.

           (3) Upon request of any Person appointed hereunder as a successor
      Trustee, the Company and the Guarantor shall execute any and all
      instruments for more fully and certainly vesting in and confirming to such
      successor Trustee all such rights, powers and trusts referred to in
      paragraph (1) or (2) of this Section, as the case may be.

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

      Section 6.10. Merger, Conversion, Consolidation or Succession to Business.

      Any Corporation into which the Trustee may be merged or converted or with
which it may be consolidated, or any Corporation resulting from any merger,
conversion or consolidation to which the Trustee shall be a party, shall be the
successor of the Trustee hereunder, without the execution or filing of any paper
or any further act on the part of any of the parties hereto. In case any
Securities shall have been authenticated but not delivered by the Trustee then
in office, any successor by merger, conversion or consolidation to such
authenticating Trustee may adopt such authentication and deliver the Securities
so authenticated with the same effect as if such successor Trustee had itself
authenticated such Securities.

      Section 6.11. Appointment of Authenticating Agent.

      The Trustee may appoint one or more Authenticating Agents acceptable to
the Company with respect to one or more series of Securities which shall be
authorized to act on behalf of the Trustee to authenticate Securities of that or
those series issued upon original issue, exchange, registration of transfer,
partial redemption or partial repayment or pursuant to Section 3.6, and
Securities so authenticated shall be entitled to the benefits of this Indenture
and shall be valid and obligatory for all purposes as if authenticated by the
Trustee hereunder. Wherever reference is


                                       65
<PAGE>

made in this Indenture to the authentication and delivery of Securities by the
Trustee or the Trustee's certificate of authentication, such reference shall be
deemed to include authentication and delivery on behalf of the Trustee by an
Authenticating Agent and a certificate of authentication executed on behalf of
the Trustee by an Authenticating Agent.

      Each Authenticating Agent must be acceptable to the Company and the
Guarantor and, except as provided in or pursuant to this Indenture, shall at all
times be a corporation that would be permitted by the Trust Indenture Act to act
as trustee under an indenture qualified under the Trust Indenture Act, is
authorized under applicable law and by its charter to act as an Authenticating
Agent and has a combined capital and surplus (computed in accordance with
Section 310(a)(2) of the Trust Indenture Act) of at least $50,000,000. If at any
time an Authenticating Agent shall cease to be eligible in accordance with the
provisions of this Section, it shall resign immediately in the manner and with
the effect specified in this Section.

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

      An Authenticating Agent may resign at any time by giving written notice
thereof to the Trustee, the Company and the Guarantor. The Trustee may at any
time terminate the agency of an Authenticating Agent by giving written notice
thereof to such Authenticating Agent, the Company and the Guarantor. Upon
receiving such a notice of resignation or upon such a termination, or in case at
any time such Authenticating Agent shall cease to be eligible in accordance with
the provisions of this Section, the Trustee may appoint a successor
Authenticating Agent which shall be acceptable to the Company and the Guarantor
and shall (i) mail written notice of such appointment by first-class mail,
postage prepaid, to all Holders of Registered Securities, if any, of the series
with respect to which such Authenticating Agent shall serve, as their names and
addresses appear in the Security Register, and (ii) if Securities of the series
are issued as Bearer Securities, publish notice of such appointment at least
once in an Authorized Newspaper in the place where such successor Authenticating
Agent has its principal office if such office is located outside the United
States. Any successor Authenticating Agent, upon acceptance of its appointment
hereunder, shall become vested with all the rights, powers and duties of its
predecessor hereunder, with like effect as if originally named as an
Authenticating Agent. No successor Authenticating Agent shall be appointed
unless eligible under the provisions of this Section.

      The Company and the Guarantor (without duplication) each agree to pay each
Authenticating Agent from time to time reasonable compensation for its services
under this Section. If the Trustee makes such payments, it shall be entitled to
be reimbursed for such payments, subject to the provisions of Section 6.6.


                                       66
<PAGE>

      The provisions of Sections 3.8, 6.3 and 6.4 shall be applicable to each
Authenticating Agent.

      If an Authenticating Agent is appointed with respect to one or more series
of Securities pursuant to this Section, the Securities of such series may have
endorsed thereon, in addition to or in lieu of the Trustee's certificate of
authentication, an alternate certificate of authentication in substantially the
following form:

      This is one of the Securities of the series designated herein referred to
in the within-mentioned Indenture.

                                    THE FIRST NATIONAL BANK OF CHICAGO, as
                                          Trustee

                                    By________________________________________
                                       as Authenticating Agent

                                    By________________________________________
                                       Authorized Officer

      If all of the Securities of any series may not be originally issued at one
time, and if the Trustee does not have an office capable of authenticating
Securities upon original issuance located in a Place of Payment where the
Company wishes to have Securities of such series authenticated upon original
issuance, the Trustee, if so requested in writing (which writing need not be
accompanied by or contained in an Officer's Certificate by the Company), shall
appoint in accordance with this Section an Authenticating Agent having an office
in a Place of Payment designated by the Company with respect to such series of
Securities.

of Preferred Securities under this Section to approve the particular form of any
proposed supplemental indenture, but it shall be sufficient if such Act shall

determine, new Securities of any series so modified as to conform, in the
opinion of the Trustee and the Company, to any such supplemental indenture may

      Section 10.1. Payment of Principal, any Premium, Interest and Additional
Amounts.

      The Company covenants and agrees for the benefit of the Holders of the
Securities of each series that it will duly and punctually pay the principal of,
any premium and interest (including any Additional Interest) on and any
Additional Amounts with respect to the Securities of such series in accordance
with the terms thereof, any Coupons appertaining thereto and this Indenture. Any
interest due on any Bearer Security on or before the Maturity thereof, and any
Additional Amounts payable with respect to such interest, shall be payable only
upon presentation and surrender of the Coupons appertaining thereto for such
interest as they severally mature.

      Section 10.2. Maintenance of Office or Agency.

      The Company and the Guarantor shall maintain in each Place of Payment for
any series of Securities an Office or Agency where Securities of such series
(but not Bearer Securities, except as otherwise provided below, unless such
Place of Payment is located outside the United States) may be presented or
surrendered for payment, where Securities of such series may be surrendered for
registration of transfer or exchange, where Securities of such series that are
convertible or exchangeable may be surrendered for conversion or exchange, and
where notices and demands to or upon the Company or the Guarantor in respect of
the Securities of such series relating thereto and this Indenture may be served.
If Securities of a series are issuable as Bearer Securities, the Company and the
Guarantor shall maintain, subject to any laws or regulations applicable thereto,
an Office or Agency in a Place of Payment for such series which is located
outside the United States where Securities of such series and any Coupons
appertaining thereto may be presented and surrendered for payment; provided,
however, that if the Securities of such series are listed on The Stock Exchange
of the United Kingdom and the Republic of Ireland or the Luxembourg Stock
Exchange or any other stock exchange located outside the United States and such
stock exchange shall so require, the Company and the Guarantor shall maintain a
Paying Agent in London, Luxembourg or any other required city located outside
the United States, as the case may be, so long as the Securities of such series
are listed on such exchange. The Company and the Guarantor 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 or the Guarantor 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,
except that Bearer Securities of such series and any Coupons appertaining
thereto may be presented and surrendered for payment at the place specified for
the purpose with respect to such Securities as provided in or pursuant to this
Indenture, and the Company and the Guarantor hereby appoint the Trustee as their
agent to receive all such presentations, surrenders, notices and demands.


                                       77
<PAGE>

      Except as otherwise provided in or pursuant to this Indenture, no payment
of principal, premium, interest or Additional Amounts with respect to Bearer
Securities shall be made at any Office or Agency in the United States or by
check mailed to any address in the United States or by transfer to an account
maintained with a bank located in the United States; provided, however, if
amounts owing with respect to any Bearer Securities shall be payable in Dollars,
payment of principal of, any premium or interest on and any Additional Amounts
with respect to any such Security may be made at the Corporate Trust Office of
the Trustee or any Office or Agency designated by the Company and the Guarantor
in the Borough of Manhattan, The City of New York, if (but only if) payment of
the full amount of such principal, premium, interest or Additional Amounts at
all offices outside the United States maintained for such purpose by the Company
and the Guarantor in accordance with this Indenture is illegal or effectively
precluded by exchange controls or other similar restrictions.

      The Company and the Guarantor may also from time to time designate one or
more other Offices or Agencies where the Securities of one or more series 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 or the Guarantor of its
obligation to maintain an Office or Agency in each Place of Payment for
Securities of any series for such purposes. The Company and the Guarantor shall
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. Unless
otherwise provided in or pursuant to this Indenture, the Company and the
Guarantor hereby designate as the Place of Payment for each series of Securities
the Borough of Manhattan, The City of New York, and initially appoint the
Corporate Trust Office of the Trustee as the Office or Agency of the Company in
the Borough of Manhattan, The City of New York for such purpose. The Company and
the Guarantor may subsequently appoint a different Office or Agency in the
Borough of Manhattan, The City of New York for the Securities of any series.

      Unless otherwise specified with respect to any Securities pursuant to
Section 3.1, if and so long as the Securities of any series (i) are denominated
in a Foreign Currency or (ii) may be payable in a Foreign Currency, or so long
as it is required under any other provision of this Indenture, then the Company
will maintain with respect to each such series of Securities, or as so required,
at least one exchange rate agent.

      Section 10.3. Money for Securities Payments to Be Held in Trust.

      If the Company shall at any time act as its own Paying Agent, or if the
Guarantor shall act as Paying Agent, with respect to any series of Securities,
it shall, on or before each due date of the principal of, any premium or
interest (including any Additional Interest) on or Additional Amounts with
respect to any of the Securities of such series, segregate and hold in trust for
the benefit of the Persons entitled thereto a sum in the currency or currencies,
currency unit or units or composite currency or currencies in which the
Securities of such series are payable (except as otherwise specified pursuant to
Section 3.1 for the Securities of such series) sufficient to pay the principal
or any premium, interest (including any Additional Interest) or Additional
Amounts so


                                       78
<PAGE>

becoming due until such sums shall be paid to such Persons or otherwise disposed
of as herein provided, and shall promptly notify the Trustee of its action or
failure so to act.

      Whenever the Company shall have one or more Paying Agents for any series
of Securities, it shall, on or prior to each due date of the principal of, any
premium or interest (including any Additional Interest) on or any Additional
Amounts with respect to any Securities of such series, deposit with any Paying
Agent a sum (in the currency or currencies, currency unit or units or composite
currency or currencies described in the preceding paragraph) sufficient to pay
the principal or any premium, interest (including any Additional Interest) or
Additional Amounts so becoming due, such sum to be held in trust for the benefit
of the Persons entitled thereto, 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 shall cause each Paying Agent for any series of Securities
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 shall:

            (1) hold all sums held by it for the payment of the principal of,
      any premium or interest (including any Additional Interest) on or any
      Additional Amounts with respect to Securities of such series in trust for
      the benefit of the Persons entitled thereto until such sums shall be paid
      to such Persons or otherwise disposed of as provided in or pursuant to
      this Indenture;

            (2) give the Trustee notice of any default by the Company or the
      Guarantor (or any other obligor upon the Securities of such series) in the
      making of any payment of principal, any premium or interest (including any
      Additional Interest) on or any Additional Amounts with respect to the
      Securities of such series; and

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

      The Company or the Guarantor may at any time, for the purpose of obtaining
the satisfaction and discharge of this Indenture or for any other purpose, pay,
or by Company Order or Guarantor Order direct any Paying Agent to pay, to the
Trustee all sums held in trust by the Company, the Guarantor or such Paying
Agent, such sums to be held by the Trustee upon the same terms as those upon
which such sums were held by the Company, the Guarantor 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 sums.

      Except as otherwise provided herein or pursuant hereto, any money
deposited with the Trustee or any Paying Agent, or then held by the Company or
the Guarantor, in trust for the payment of the principal of, any premium or
interest (including any Additional Interest) on or any Additional Amounts with
respect to any Security of any series or any Coupon appertaining thereto and
remaining unclaimed for two years after such principal or any such premium or


                                       79
<PAGE>

interest or any such Additional Amounts shall have become due and payable shall
be paid to the Company on Company Request (or if deposited by the Guarantor,
paid to the Guarantor on Guarantor Request), or (if then held by the Company or
the Guarantor) shall be discharged from such trust; and the Holder of such
Security or any Coupon appertaining thereto shall thereafter, as an unsecured
general creditor, look only to the Company and the Guarantor for payment
thereof, and all liability of the Trustee or such Paying Agent with respect to
such trust money, and all liability of the Company as trustee thereof, shall
thereupon cease; provided, however, that the Trustee or such Paying Agent,
before being required to make any such repayment, may at the expense of the
Company and the Guarantor cause to be published once, in an Authorized Newspaper
in each Place of Payment for such series or to be mailed to Holders of
Registered Securities of such series, or both, notice that such money remains
unclaimed and that, after a date specified therein, which shall not be less than
30 days from the date of such publication or mailing nor shall it be later than
two years after such principal and any premium or interest or Additional Amounts
shall have become due and payable, any unclaimed balance of such money then
remaining will be repaid to the Company or the Guarantor, as the case may be.

      Section 10.4. Additional Amounts.

      If any Securities of a series provide for the payment of Additional
Amounts, the Company agrees to pay to the Holder of any such Security or any
Coupon appertaining thereto Additional Amounts as provided in or pursuant to
this Indenture or such Securities. Whenever in this Indenture there is
mentioned, in any context, the payment of the principal of or any premium or
interest on, or in respect of, any Security of any series or any Coupon or the
net proceeds received on the sale or exchange of any Security of any series,
such mention shall be deemed to include mention of the payment of Additional
Amounts provided by the terms of such series established hereby or pursuant
hereto to the extent that, in such context, Additional Amounts are, were or
would be payable in respect thereof pursuant to such terms, and express mention
of the payment of Additional Amounts (if applicable) in any provision hereof
shall not be construed as excluding Additional Amounts in those provisions
hereof where such express mention is not made.

      Except as otherwise provided in or pursuant to this Indenture or the
Securities of the applicable series, if the Securities of a series provide for
the payment of Additional Amounts, at least 10 days prior to the first Interest
Payment Date with respect to such series of Securities (or if the Securities of
such series shall not bear interest prior to Maturity, the first day on which a
payment of principal is made), and at least 10 days prior to each date of
payment of principal or interest if there has been any change with respect to
the matters set forth in the below-mentioned Officer's Certificate, the Company
shall furnish to the Trustee and the principal Paying Agent or Paying Agents, if
other than the Trustee, an Officer's Certificate instructing the Trustee and
such Paying Agent or Paying Agents whether such payment of principal of and
premium, if any, or interest on the Securities of such series shall be made to
Holders of Securities of such series or the Coupons appertaining thereto who are
United States Aliens without withholding for or on account of any tax,
assessment or other governmental charge described in the Securities of such
series. If any such withholding shall be required, then such Officer's
Certificate shall specify by


                                       80
<PAGE>

country the amount, if any, required to be withheld on such payments to such
Holders of Securities or Coupons, and the Company agrees to pay to the Trustee
or such Paying Agent the Additional Amounts required by the terms of such
Securities. The Company covenants to indemnify the Trustee and any Paying Agent
for, and to hold them harmless against, any loss, liability or expense
reasonably incurred without negligence or bad faith on their part arising out of
or in connection with actions taken or omitted by any of them in reliance on any
Officer's Certificate furnished pursuant to this Section 10.4.

      Section 10.5. Corporate Existence.

      Subject to Article 8, the Company and the Guarantor shall do or cause to
be done all things necessary to preserve and keep in full force and effect their
respective corporate existences and that of each of their respective
Subsidiaries and their respective rights (charter and statutory) and franchises;
provided, however, that the foregoing shall not obligate the Company or the
Guarantor or any of their respective Subsidiaries to preserve any such right or
franchise if the Company, the Guarantor or any such Subsidiary shall determine
that the preservation thereof is no longer desirable in the conduct of its
business or the business of such Subsidiary and that the loss thereof is not
disadvantageous in any material respect to any Holder.

      Section 10.6. Waiver of Certain Covenants.

      The Company or the Guarantor, as the case may be, may omit in any
particular instance to comply with any term, provision or condition set forth in
Section 10.5 with respect to the Securities of any series if before the time for
such compliance the Holders of at least a majority in principal amount of the
Outstanding Securities of such series, by Act of such Holders, either shall
waive such compliance in such instance or generally shall have waived compliance
with such term, provision or condition, but no such waiver shall extend to or
affect such term, provision or condition except to the extent so expressly
waived, and, until such waiver shall become effective, the obligations of the
Company and the Guarantor and the duties of the Trustee in respect of any such
term, provision or condition shall remain in full force and effect.

      Section 10.7. Company Statement as to Compliance; Notice of Certain
Defaults.

      the end of each fiscal year, a written statement (which need not be

            default known to him or her and the nature and status thereof, and
            (b) no event has occurred and is continuing which is, or after
            notice or lapse of time or both would become, an Event of Default,
            or, if such an event has occurred and is continuing, specifying each

            (3) The Trustee shall have no duty to monitor the Company's
      compliance with the covenants contained in this Article 10 other than as

      after the end of each fiscal year, a written statement (which need not be
      contained in or accompanied by a Guarantor's Officer's Certificate) signed
      by the principal executive officer, the principal financial officer or the
      principal accounting officer of the Guarantor, stating that

                  (a) a review of the activities of the Guarantor during such
            year and of performance under this Indenture has been made under his
            or her supervision, and

                  (b) to the best of his or her knowledge, based on such review,
            (a) the Guarantor has complied with conditions and covenants imposed
            on it under this Indenture throughout such year, or, if there has

      Section 10.9. Additional Sums.

      In the case of Securities of a series issued to an ACE Trust, except as
otherwise specified as contemplated by Section 3.1, in the event that (i) such
ACE Trust is the Holder of all of the Outstanding Securities of such series,
(ii) a Tax Event in respect of such ACE Trust shall have occurred and be
continuing and (iii) the Company shall not have (i) redeemed the Securities of
such series pursuant to Section 11.8 or (ii) terminated such ACE Trust pursuant
to Section 9.2(b) of the related Trust Agreement, the Company shall pay to such
ACE Trust (and its permitted successors or assigns under the related Trust
Agreement), for so long as such ACE Trust (or its permitted successor or
assignee) is the registered holder of any Securities of such series, such
additional amounts as may be necessary in order that the amount of Distributions
then due and payable by such ACE Trust on the related Preferred Securities and
Common Securities that at any time remain outstanding in accordance with the
terms thereof shall not be reduced as a result of any Additional Taxes (the
"Additional Sums"). Whenever in this Indenture there is mentioned, in any
context, the payment of the principal of or any premium or interest on, or in
respect of, any Security of any series or any Coupon or the net proceeds
received on the sale or exchange of any Security of any series, such mention
shall be deemed to include mention of the payment of Additional Sums provided by
the terms of such series established hereby or pursuant hereto to the extent
that, in such context, Additional Sums are, were or would be payable in respect
thereof pursuant to such terms, and express mention of the payment of Additional
Sums (if applicable) in any provision hereof shall not be construed as excluding
Additional Sums in those provisions hereof where such express mention is not
made, provided, however, that the extension of an interest payment period
pursuant to Section 3.11 or the terms of the applicable Securities shall not
extend the payment of any Additional Sums that may be due and payable during
such interest payment period.

      Section 10.10. Prohibition Against Dividends, etc.

      Except as otherwise specified as contemplated by Section 3.1, the Company
and the Guarantor each covenant and agree with each Holder of Securities of a
series issued to an ACE Trust that it will not, and will not permit any of its
Subsidiaries to, (a) declare or pay any dividends or distributions on, or
redeem, purchase, acquire or make a liquidation payment with respect to, any of
the outstanding capital stock of the Company or the Guarantor, as the case may
be, or (b) make any payment of principal of, interest or premium, if any, on or
repay, repurchase or redeem any debt security of the Company or the Guarantor,
as the case may be, that ranks junior in interest to the Securities of such
series or the Guarantee in respect thereof, as the case may be, or make any
guarantee payments with respect to any guarantee by the Company or the
Guarantor, as the case may be, of the debt securities of any Subsidiary of the
Company or the Guarantor, as the case may be, if such guarantee ranks junior in
interest to the Securities of such series or the Guarantee in respect thereof,
as the case may be (other than (i) dividends or distributions on the Capital
Stock of the Company paid or made to the Guarantor and dividends or
distributions in Common Stock of the Company or the Guarantor, as the case may
be, (ii) redemptions or purchases of any rights outstanding under a shareholder
rights plan of the Company or the Guarantor, as the case may be, or the

the issuance of stock under such plans in the future, (iii) payments under any
Preferred Securities Guarantee, and (iv) purchases of Common Stock related to
the issuance of Common Stock under any benefit plans of the Company or the
Guarantor, as the case may be, for its respective directors, officers or
employees) if at such time (1) there shall have occurred any event of which the
Company or the Guarantor, as the case may be, has actual knowledge that (A) with
the giving of notice or the lapse of time or both, would constitute an Event o
Default hereunder and (B) in respect of which the Company or the Guarantor, as
the case may be, shall not have taken reasonable steps to cure, (2) the
Guarantor shall be in default with respect to its payment of any obligations
under the related Preferred Securities Guarantee or (3) the Company shall have
given notice of its election to begin an Extension Period as provided herein
with respect to the Securities of such series and shall not have rescinded such
notice, or such Extension Period, or any extension thereof, shall be continuing.

      Section 10.11. Payment of Expenses of each ACE Trust.

      The Guarantor covenants for the benefit of the Holders of each series of
Securities to pay or cause to be paid all of the obligations, costs and expenses
of each ACE Trust (other than payments in respect of Trust Securities) in
accordance with the provisions of its Trust Agreement and to pay the taxes of
such ACE Trust in accordance with the provisions of its Trust Agreement in order
to permit such ACE Trust to make distributions on and redemptions of its
Preferred Securities in accordance with such Trust Agreement.

      Section 10.12. Ownership of Common Securities.

      The Company covenants, as to each series of Securities issued to an ACE
Trust in connection with the issuance of Preferred Securities and Common
Securities by that ACE Trust, (a) to maintain directly or indirectly 100%
ownership of the Common Securities of such ACE Trust; provided, however, that
any permitted successor of the Company hereunder may succeed to the Company's
ownership of such Common Securities, (b) not to voluntarily dissolve, wind-up or
liquidate such ACE Trust, except in connection with (i) a distribution of the
Securities of such series to the holders of Preferred Securities and Common
Securities in liquidation of such ACE Trust, (ii) the redemption of all of the
Preferred Securities and Common Securities of such ACE Trust or (iii) certain
mergers, consolidations or amalgamations, each as permitted by the Trust

                                   ARTICLE 11

                            REDEMPTION OF SECURITIES

      Section 11.1. Applicability of Article.

      Redemption of Securities of any series at the option of the Company as
permitted or required by the terms of such Securities shall be made in
accordance with the terms of such Securities and (except as otherwise provided
herein or pursuant hereto) this Article.

      Section 11.2. Election to Redeem; Notice to Trustee.

      The election of the Company to redeem any Securities shall be evidenced by
or pursuant to a Board Resolution. In case of any redemption at the election of
the Company of (a) less than all of the Securities of any series or (b) all of
the Securities of any series, with the same issue date, interest rate or
formula, Stated Maturity and other terms, the Company shall, at least 60 days
prior to the Redemption Date fixed by the Company (unless a shorter notice shall
be satisfactory to the Trustee), notify the Trustee of such Redemption Date and
of the principal amount of Securities of such series to be redeemed. If the
Securities of a series are held by an ACE Trust, the Company shall also deliver
a copy of such notice to the Property Trustee of such ACE Trust.

      Section 11.3. Selection by Trustee of Securities to be Redeemed.

      If less than all of the Securities of any series with the same issue date,
interest rate or formula, Stated Maturity and other terms are to be redeemed,
the particular Securities to be redeemed shall be selected not more than 60 days
prior to the Redemption Date by the Trustee from the Outstanding Securities of
such series not previously called for redemption, by such method as the Trustee
shall deem fair and appropriate and which may provide for the selection for
redemption of portions of the principal amount of Registered Securities of such
series; provided, however, that no such partial redemption shall reduce the
portion of the principal amount of a Registered Security of such series not
redeemed to less than the minimum denomination for a Security of such series
established herein or pursuant hereto.

      The Trustee shall promptly notify the Company and the Security Registrar
(if other than itself) in writing of the Securities selected for redemption and,
in the case of any Securities selected for partial redemption, the principal
amount thereof to be redeemed.

      For all purposes of this Indenture, unless the context otherwise requires,
all provisions relating to the redemption of Securities shall relate, in the
case of any Securities redeemed or to be redeemed only in part, to the portion
of the principal of such Securities which has been or is to be redeemed.

      Unless otherwise specified in or pursuant to this Indenture or the
Securities of any series, if any Security selected for partial redemption is
converted into other securities of the Company


                                       85
<PAGE>

or exchanged for securities of the Guarantor or another issuer in part before
termination of the conversion or exchange right with respect to the portion of
the Security so selected, the converted portion of such Security shall be deemed
(so far as may be) to be the portion selected for redemption. Securities which
have been converted or exchanged during a selection of Securities to be redeemed
shall be treated by the Trustee as Outstanding for the purpose of such
selection.

      Section 11.4. Notice of Redemption.

      Notice of redemption shall be given in the manner provided in Section 1.6,
not less than 30 nor more than 60 days prior to the Redemption Date, unless a
shorter period is specified in the Securities to be redeemed, to the Holders of
Securities to be redeemed. Failure to give notice by mailing in the manner
herein provided to the Holder of any Registered Securities designated for
redemption as a whole or in part, or any defect in the notice to any such
Holder, shall not affect the validity of the proceedings for the redemption of
any other Securities or portion thereof.

      Any notice that is mailed to the Holder of any Registered Securities in
the manner herein provided shall be conclusively presumed to have been duly
given, whether or not such Holder receives the notice.

      All notices of redemption shall state:

            (1) the Redemption Date,

            (2) the Redemption Price,

            (3) if less than all Outstanding Securities of any series are to be
      redeemed, the identification (and, in the case of partial redemption, the
      principal amount) of the particular Security or Securities to be redeemed,

            (4) in case any Security is to be redeemed in part only, the notice
      which relates to such Security shall state that on and after the
      Redemption Date, upon surrender of such Security, the Holder of such
      Security will receive, without charge, a new Security or Securities of
      authorized denominations for the principal amount thereof remaining
      unredeemed,

            (5) that, on the Redemption Date, the Redemption Price shall become
      due and payable upon each such Security or portion thereof to be redeemed,
      and, if applicable, that interest thereon shall cease to accrue on and
      after said date,

            (6) the place or places where such Securities, together (in the case
      of Bearer Securities) with all Coupons appertaining thereto, if any,
      maturing after the Redemption Date, are to be surrendered for payment of
      the Redemption Price and any accrued interest and Additional Amounts
      pertaining thereto,


                                       86
<PAGE>

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

            (8) that, unless otherwise specified in such notice, Bearer
      Securities of any series, if any, surrendered for redemption must be
      accompanied by all Coupons maturing subsequent to the date fixed for
      redemption or the amount of any such missing Coupon or Coupons will be
      deducted from the Redemption Price, unless security or indemnity
      satisfactory to the Company, the Guarantor, the Trustee and any Paying
      Agent is furnished,

            (9) if Bearer Securities of any series are to be redeemed and no
      Registered Securities of such series are to be redeemed, and if such
      Bearer Securities may be exchanged for Registered Securities not subject
      to redemption on the Redemption Date pursuant to Section 3.5 or otherwise,
      the last date, as determined by the Company, on which such exchanges may
      be made,

            (10) in the case of Securities of any series that are convertible
      into Common Stock of the Company or exchangeable for other securities, the
      conversion or exchange price or rate, the date or dates on which the right
      to convert or exchange the principal of the Securities of such series to
      be redeemed will commence or terminate and the place or places where such
      Securities may be surrendered for conversion or exchange, and

            (11) the CUSIP number or the Euroclear or the Cedel reference
      numbers of such Securities, if any (or any other numbers used by a
      Depository to identify such Securities).

      A notice of redemption published as contemplated by Section 1.6 need not
identify particular Registered Securities to be redeemed.

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

      Section 11.5. Deposit of Redemption Price.

      On or prior to any Redemption Date, the Company or the Guarantor shall
deposit, with respect to the Securities of any series called for redemption
pursuant to Section 11.4, with the Trustee or with a Paying Agent (or, if the
Company is acting as its own Paying Agent or the Guarantor is acting as Paying
Agent, segregate and hold in trust as provided in Section 10.3) an amount of
money in the applicable Currency sufficient to pay the Redemption Price of, and
(except if the Redemption Date shall be an Interest Payment Date, unless
otherwise specified pursuant to Section 3.1 or in the Securities of such series)
any accrued interest (including any Additional Interest) on and Additional
Amounts with respect thereto, all such Securities or portions thereof which are
to be redeemed on that date.


                                       87
<PAGE>

      Section 11.6. Securities Payable on Redemption Date.

      Notice of redemption having been given as aforesaid, the Securities 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 and the Guarantor shall default in the payment of the Redemption Price
and accrued interest) such Securities shall cease to bear interest and the
Coupons for such interest appertaining to any Bearer Securities so to be
redeemed, except to the extent provided below, shall be void. Upon surrender of
any such Security for redemption in accordance with said notice, together with
all Coupons, if any, appertaining thereto maturing after the Redemption Date,
such Security shall be paid by the Company at the Redemption Price, together
with any accrued interest and Additional Amounts to the Redemption Date;
provided, however, that, except as otherwise provided in or pursuant to this
Indenture or the Bearer Securities of such series, installments of interest on
Bearer Securities whose Stated Maturity is on or prior to the Redemption Date
shall be payable only upon presentation and surrender of Coupons for such
interest (at an Office or Agency located outside the United States except as
otherwise provided in Section 10.2), and provided, further, that, except as
otherwise specified in or pursuant to this Indenture or the Registered
Securities of such series, installments of interest on Registered Securities
whose Stated Maturity is on or prior to the Redemption Date shall be payable to
the Holders of such Securities, or one or more Predecessor Securities,
registered as such at the close of business on the Regular Record Dates therefor
according to their terms and the provisions of Section 3.7.

      If any Bearer Security surrendered for redemption shall not be accompanied
by all appurtenant Coupons maturing after the Redemption Date, such Security may
be paid after deducting from the Redemption Price an amount equal to the face
amount of all such missing Coupons, or the surrender of such missing Coupon or
Coupons may be waived by the Company and the Trustee if there be furnished to
them such security or indemnity as they may require to save each of them and any
Paying Agent harmless. If thereafter the Holder of such Security shall surrender
to the Trustee or any Paying Agent any such missing Coupon in respect of which a
deduction shall have been made from the Redemption Price, such Holder shall be
entitled to receive the amount so deducted; provided, however, that any interest
or Additional Amounts represented by Coupons shall be payable only upon
presentation and surrender of those Coupons at an Office or Agency for such
Security located outside of the United States except as otherwise provided in
Section 10.2.

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

      Section 11.7. Securities Redeemed in Part.

      Any Registered Security which is to be redeemed only in part shall be
surrendered at any Office or Agency for such Security (with, if the Company or
the Trustee so requires, 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


                                       88
<PAGE>

Company shall execute and the Trustee shall authenticate and deliver to the
Holder of such Security without service charge, a new Registered Security or
Securities of the same series, containing identical terms and provisions, 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 Security so surrendered. If a Security in global form is so surrendered, the
Company shall execute, and the Trustee shall authenticate and deliver to the
U.S. Depository or other Depository for such Security in global form as shall be
specified in the Company Order with respect thereto to the Trustee, without
service charge, a new Security in global form in a denomination equal to and in
exchange for the unredeemed portion of the principal of the Security in global
form so surrendered.

      Section 11.8. Right of Redemption of Securities Issued to an ACE Trust.

      In the case of the Securities of a series issued to an ACE Trust, except
as otherwise specified as contemplated by Section 3.1, if a Special Event in
respect of such ACE Trust shall occur and be continuing, the Company may, at its
option, redeem the Securities of such series within 90 days of the occurrence of
such Special Event, in whole but not in part, subject to the provisions of this
Section 11.8 and the other provisions of this Article 11. Unless otherwise
specified in or pursuant to this Indenture or the Securities of such series, the
redemption price for any Security so redeemed pursuant to this Section 11.8
shall be equal to 100% of the principal amount of such Securities then
Outstanding plus accrued and unpaid interest, including any Additional Interest,
to the date fixed for redemption.

                                   ARTICLE 12

                                  SINKING FUNDS

      Section 12.1. Applicability of Article.

      The provisions of this Article shall be applicable to any sinking fund for
the retirement of Securities of a series, except as otherwise permitted or
required in or pursuant to this Indenture or any Security of such series issued
pursuant to this Indenture.

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

      Section 12.2. Satisfaction of Sinking Fund Payments with Securities.

      The Company or the Guarantor may, in satisfaction of all or any part of
any sinking fund payment with respect to the Securities of any series to be made
pursuant to the terms of such Securities (1) deliver Outstanding Securities of
such series (other than any of such Securities previously called for redemption
or any of such Securities in respect of which cash shall have been released to
the Company), together in the case of any Bearer Securities of such series with
all unmatured Coupons appertaining thereto, and (2) apply as a credit Securities
of such series which have been redeemed either at the election of the Company
pursuant to the terms of such series of Securities or through the application of
permitted optional sinking fund payments pursuant to the terms of such
Securities, provided that such series of Securities have not been previously so
credited. Such Securities shall be received and credited for such purpose by the
Trustee at the Redemption Price specified in such Securities for redemption
through operation of the sinking fund and the amount of such sinking fund
payment shall be reduced accordingly. If, as a result of the delivery or credit
of Securities of any series in lieu of cash payments pursuant to this Section
12.2, the principal amount of Securities of such series to be redeemed in order
to satisfy the remaining sinking fund payment shall be less than $100,000, the
Trustee need not call Securities of such series for redemption, except upon
Company Request or Guarantor Request, and such cash payment shall be held by the
Trustee or a Paying Agent and applied to the next succeeding sinking fund
payment, provided, however, that the Trustee or such Paying Agent shall at the
request of the Company or the Guarantor from time to time pay over and deliver
to the Company or the Guarantor, as the case may be, any cash payment so being
held by the Trustee or such Paying Agent upon delivery by the Company or the
Guarantor to the Trustee of Securities of that series purchased by the Company
or the Guarantor having an unpaid principal amount equal to the cash payment
requested to be released to the Company or the Guarantor.

      Section 12.3. Redemption of Securities for Sinking Fund.

      Not less than 75 days prior to each sinking fund payment date for any
series of Securities, the Company shall deliver to the Trustee an Officer's
Certificate specifying the amount of the next ensuing mandatory sinking fund
payment for that series pursuant to the terms of that series, the portion
thereof, if any, which is to be satisfied by payment of cash and the portion
thereof, if any, which is to be satisfied by delivering and crediting of
Securities of that series pursuant to Section 12.2, and the optional amount, if
any, to be added in cash to the next ensuing mandatory sinking fund payment, and
will also deliver to the Trustee any Securities to be so credited and not
theretofore delivered. If such Officer's Certificate shall specify an optional
amount to be added in cash to the next ensuing mandatory sinking fund payment,
the Company shall thereupon be obligated to pay the amount therein specified.
Not less than 60 days before each such sinking fund payment date the Trustee
shall select the Securities to be redeemed upon such sinking fund payment date
in the manner specified in Section 11.3 and cause notice of the redemption
thereof to be given in the name of and at the expense of the Company in the
manner provided in Section 11.4. Such notice having been duly given, the
redemption of such Securities shall be made upon the terms and in the manner
stated in Sections 11.6 and 11.7.

                      REPAYMENT AT THE OPTION OF HOLDERS

      Section 13.1. Applicability of Article.

      Securities of any series which are repayable at the option of the Holders
thereof before their Stated Maturity shall be repaid in accordance with the
terms of the Securities of such series. The repayment of any principal amount of
Securities pursuant to such option of the Holder to require repayment of
Securities before their Stated Maturity, for purposes of Section 3.9, shall not
operate as a payment, redemption or satisfaction of the Indebtedness represented
by such Securities unless and until the Company, at its option, shall deliver or
surrender the same to the Trustee with a directive that such Securities be
cancelled. Notwithstanding anything to the contrary contained in this Section
13.1, in connection with any repayment of Securities, the Company may arrange
for the purchase of any Securities by an agreement with one or more investment
bankers or other purchasers to purchase such Securities by paying to the Holders
of such Securities on or before the close of business on the repayment date an
amount not less than the repayment price payable by the Company on repayment of
such Securities, and the obligation of the Company to pay the repayment price of
such Securities shall be satisfied and discharged to the extent such payment is
so paid by such purchasers.

      Section 14.1. Applicability of Article.

      Whenever this Indenture provides for (i) any action by, or the
determination of any of the rights of, Holders of Securities of any series in
which not all of such Securities are denominated in the same Currency, or (ii)
any distribution to Holders of Securities, in the absence of any provision to
the contrary in the form of Security of any particular series or pursuant to
this Indenture or the Securities, any amount in respect of any Security
denominated in a Currency other than Dollars shall be treated for any such
action or distribution as that amount of Dollars that could be obtained for such
amount on such reasonable basis of exchange and as of the record date with
respect to Registered Securities of such series (if any) for such action,
determination of rights or distribution (or, if there shall be no applicable
record date, such other date reasonably proximate to the date of such action,
determination of rights or distribution) as the Company or the Guarantor may
specify in a written notice to the Trustee.

                      MEETINGS OF HOLDERS OF SECURITIES

      Section 15.1. Purposes for Which Meetings May Be Called.

      A meeting of Holders of Securities of any series may be called at any time
and from time to time pursuant to this Article to make, give or take any
request, demand, authorization, direction, notice, consent, waiver or other Act
provided by this Indenture to be made, given or taken by Holders of Securities
of such series.

      Section 15.2. Call, Notice and Place of Meetings.

           (1) The Trustee may at any time call a meeting of Holders of

      Holders of Securities of any series, setting forth the time and the place
      of such meeting and in general terms the action proposed to be taken at
      such meeting, shall be given, in the manner provided in Section 1.6, not
      less than 21 nor more than 180 days prior to the date fixed for the
      meeting.

           (2) In case at any time the Company (by or pursuant to a Board
      Resolution), the Guarantor (by or pursuant to a Guarantor's Board
      Resolution) or the Holders of at least 10% in principal amount of the
      Outstanding Securities of any series shall have requested the Trustee to
      call a meeting of the Holders of Securities of such series for any purpose
      specified in Section 15.1, by written request setting forth in reasonable
      detail the action proposed to be taken at the meeting, and the Trustee
      shall not have mailed notice of or made the first publication of the
      notice of such meeting within 21 days after receipt of such request
      (whichever shall be required pursuant to Section 1.6) or shall not
      thereafter proceed to cause the meeting to be held as provided herein,
      then the Company, the Guarantor or the Holders of Securities of such
      series in the amount above specified, as the case may be, may determine
      the time and the place in the Borough of Manhattan, The City of New York,
      or, if Securities of such series are to be issued as Bearer Securities, in

Holders of Securities of such series. In the absence of a quorum within 30

convened at the request of Holders of Securities of such series, be dissolved.
In any other case the meeting may be adjourned for a period of not less than 10
days as determined by the chairman of the meeting prior to the adjournment of
such meeting. In the absence of a quorum at any reconvened meeting, such
reconvened meeting may be further adjourned for a period of not less than 10
days as determined by the chairman of the meeting prior to the adjournment of
such reconvened meeting. Notice of the reconvening of any adjourned meeting

provided, however, that, except as limited by the proviso to Section 9.2, any

may be adopted at a meeting or an adjourned meeting duly reconvened and at which
a quorum is present as aforesaid by the affirmative vote of the Holders of such

appertaining thereto, whether or not such Holders were present or represented at
the meeting.

      Section 15.5. Determination of Voting Rights; Conduct and Adjournment of
Meetings.

           (1) Notwithstanding any other provisions of this Indenture, the
      Trustee may make such reasonable regulations as it may deem advisable for

      and in regard to the appointment and duties of inspectors of votes, the
      submission and examination of proxies, certificates and other evidence of
      the right to vote, and such other matters concerning the conduct of the
      meeting as it shall


                                       93

      specified in Section 1.4 and the appointment of any proxy shall be proved
      in the manner specified in Section 1.4 or by having the signature of the
      person executing the proxy witnessed or guaranteed by any trust company,
      bank or banker authorized by Section 1.4 to certify to the holding of
      Bearer Securities. Such regulations may provide that written instruments
      appointing proxies, regular on their face, may be presumed valid and
      genuine without the proof specified in Section 1.4 or other proof.

            (2) The Trustee shall, by an instrument in writing, appoint a
      temporary chairman of the meeting, unless the meeting shall have been
      called by the Company or by Holders of Securities as provided in Section
      15.2(2), in which case the Company, the Guarantor or the Holders of
      Securities of the series calling the meeting, as the case may be, shall in
      like manner appoint a temporary chairman. A permanent chairman and a
      permanent secretary of the meeting shall be elected by vote of the Persons
      entitled to vote a majority in principal amount of the Outstanding
      Securities of such series represented at the meeting.

            (3) At any meeting, each Holder of a Security of such series or
      proxy shall be entitled to one vote for each $1,000 principal amount of
      Securities of such series held or represented by him; provided, however,
      that no vote shall be cast or counted at any meeting in respect of any
      Security challenged as not Outstanding and ruled by the chairman of the
      meeting to be not Outstanding. The chairman of the meeting shall have no
      right to vote, except as a Holder of a Security of such series or proxy.

            (4) Any meeting of Holders of Securities of any series duly called
      pursuant to Section 15.2 at which a quorum is present may be adjourned
      from time to time by Persons entitled to vote a majority in principal
      amount of the Outstanding Securities of such series represented at the
      meeting; and the meeting may be held as so adjourned without further
      notice.

      Section 15.6. Counting Votes and Recording Action of Meetings.

      The vote upon any resolution submitted to any meeting of Holders of
Securities of any series shall be by written ballots on which shall be
subscribed the signatures of the Holders of Securities of such series or of
their representatives by proxy and the principal amounts and serial numbers of
the Outstanding Securities of such series held or represented by them. The
permanent chairman of the meeting shall appoint two inspectors of votes who
shall count all votes cast at the meeting for or against any resolution and who
shall make and file with the secretary of the meeting their verified written
reports in triplicate of all votes cast at the meeting. A record, at least in
triplicate, of the proceedings of each meeting of Holders of Securities of any
series shall be prepared by the secretary of the meeting and there shall be
attached to said record the original reports of the inspectors of votes on any
vote by ballot taken thereat and affidavits by one or more persons having
knowledge of the facts setting forth a copy of the notice of the meeting and
showing that said notice was given as provided in Section 15.2 and, if
applicable,


                                       94
<PAGE>

Section 15.4. Each copy shall be signed and verified by the affidavits of the
permanent chairman and secretary of the meeting and one such copy shall be
delivered to the Company and the Guarantor, and another to the Trustee to be
preserved by the Trustee, the latter to have attached thereto the ballots voted
at the meeting. Any record so signed and verified shall be conclusive evidence
of the matters therein stated.

Resolution, Officer's Certificate and Guarantor's Officer's Certificate
("Additional Provisions") by such Holder's acceptance thereof likewise covenants
and agrees, that all Securities shall be issued subject to the provisions of
this Article 16; and each Holder of a Security, whether upon original issue or
upon transfer or assignment thereof, accepts and agrees to be bound by such

Senior Indebtedness with respect to such series, whether outstanding at the date
of this Indenture or thereafter incurred.

      No provision of this Article 16 shall prevent the occurrence of any
default or Event of Default hereunder.

      Section 16.2. Default on Company 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 amount due on any
Company Senior Indebtedness with respect to the Securities of any series, or in
the event that the maturity of any Company Senior Indebtedness with respect to
the Securities of any series has been accelerated because of a default, then, in
either case, no payment shall be made by the Company with respect to the
principal (including redemption and sinking fund payments) of, any premium or
interest (including any Additional Interest) on, or any Additional Amounts with
respect to, the Securities of such series.

      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 16.2, such payment shall be held in trust for the
benefit of, and shall be paid over or delivered to, the holders of such Company
Senior Indebtedness or their respective representatives, or to the trustee or
trustees under any indenture pursuant to which any of such Company Senior


                                       95

Indebtedness may have been issued, as their respective interests may appear, but
only to the extent that the holders of such Company 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 such
Company Senior Indebtedness and only the amounts specified in such notice to the
Trustee shall be paid to the holders of such Company Senior Indebtedness.

of any kind or character, whether in cash, property or securities, to creditors
upon any dissolution, winding-up, liquidation or reorganization of the Company,
whether voluntary or involuntary, or in bankruptcy, insolvency, receivership or
other proceedings, all amounts due upon all Company Senior Indebtedness with
respect to the Securities of any series shall first be paid in full, or payment
thereof provided for in money in accordance with its terms, before any payment
is made by the Company on account of the principal of, premium or interest
(including any Additional Interest) on, or Additional Amounts with respect to,
the Securities of such series; and upon any such dissolution, winding-up,
liquidation or reorganization, or in any such bankruptcy, insolvency,
receivership or other proceeding, 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 or the Trustee would be entitled to receive
from the Company, except for the provisions of this Article 16, 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 or
by the Trustee under this Indenture if received by them or it, directly to the
holders of such Company Senior Indebtedness (pro rata to such holders on the
basis of the respective amounts of such Company 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 Company Senior Indebtedness may have been
issued, as their respective interests may appear, to the extent necessary to pay
such Company 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 Company Senior Indebtedness, before any payment or distribution is made to
the Holders of the Securities of such series 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 before all such Company 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 such Company Senior Indebtedness or
their representative or representatives, or to the trustee or trustees under any
indenture pursuant to which any instruments evidencing such Company Senior
Indebtedness may have been issued, as their respective interests may appear, as
calculated by the Company, for application to the payment of all such Company
Senior Indebtedness remaining unpaid to the extent necessary to pay such Company

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 16 with respect to
the Securities of the relevant series to the payment of all Company Senior
Indebtedness with respect to the Securities of such series that may at the time
be outstanding, provided that (i) such Company 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 Company Senior
Indebtedness are not, without the consent of such holders, altered by such

the Company following the conveyance, transfer or lease of its property as an
entirety, or substantially as an entirety, to another Person upon the terms and
conditions provided for in Sections 8.1 and 8.2 of this Indenture shall not be
deemed a dissolution, winding-up, liquidation or reorganization for the purposes
of this Section 16.3 if such other Person shall, as a part of such
consolidation, merger, conveyance or transfer, comply with the conditions stated
in Sections 8.1 and 8.2 of this Indenture. Nothing in Section 16.2 or in this
Section 16.3 shall apply to claims of, or payments to, the Trustee under or
pursuant to Section 6.6 of this Indenture.

      Section 16.4. Subrogation.

      Subject to the payment in full of all Company Senior Indebtedness with
respect to the Securities of any series, the rights of the Holders of the
Securities of such series shall be subrogated to the rights of the holders of
such Company Senior Indebtedness to receive payments or distributions of cash,
property or securities of the Company applicable to such Company Senior
Indebtedness until the principal of, any premium and interest (including any
Additional Interest) on, and any Additional Amounts with respect to, the
Securities of such series shall be paid in full; and, for the purposes of such
subrogation, no payments or distributions to the holders of such Company Senior
Indebtedness of any cash, property or securities to which the Holders or the
Trustee would be entitled except for the provisions of this Article 16, and no
payment over pursuant to the provisions of this Article 16 to or for the benefit
of the holders of such Company Senior Indebtedness by Holders of the Securities
of such series or the Trustee, shall, as between the Company, its creditors

Securities of such series, be deemed to be a payment by the Company to or on
account of such Company Senior Indebtedness. It is understood that the
provisions of this Article 16 are and are intended solely for the purposes of
defining the relative rights of the Holders of the Securities of each series, on
the one hand, and the holders of the Company Senior Indebtedness with respect to
the Securities of such series on the other hand.

Additional Provisions or in the Securities of any series is intended to or shall
impair, as between the Company, its creditors other than the holders of Company
Senior Indebtedness with respect to the Securities of such series, and the
Holders of the Securities of such series, the obligation of the Company, which
is absolute and unconditional, to pay to the Holders of the Securities of such
series the principal of, any premium and interest (including any Additional
Interest) on, and any Additional Amounts with respect to, the Securities of such
series 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 Securities of such series and creditors of the Company, other
than the holders of such Company Senior Indebtedness, nor shall anything herein
or therein prevent the Trustee or the Holder of any Security of such series from
exercising all remedies otherwise permitted by applicable law upon default under
this Indenture, subject to the rights, if any, under this Article 16 of the
holders of such Company Senior Indebtedness in respect of cash, property or
securities of the Company, as the case may be, received upon the exercise of any
such remedy.

      Upon any payment or distribution of assets of the Company referred to in
this Article 16, the Trustee, subject to the provisions of Article 6 of this
Indenture, and the Holders shall be entitled to conclusively 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 Securities of any series, for the purposes of ascertaining
the Persons entitled to participate in such distribution, the holders of Company
Senior Indebtedness with respect to the Securities of such series 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 16.

      Section 16.5. Trustee to Effectuate Subordination.

      Each Holder of Securities 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 16 and appoints the Trustee such Holder's attorney-in-fact for any and
all such purposes.

      Section 16.6. 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 that would prohibit the making of
any payment of monies to or by the Trustee in respect of the Securities of any
series pursuant to the provisions of this Article 16. Notwithstanding the
provisions of this Article 16 or any other provision of this Indenture or any
Additional Provisions, the Trustee shall not be charged with knowledge of the
existence of any facts that would prohibit the making of any payment of monies
to or by the Trustee in respect of the Securities of any series pursuant to the
provisions of this Article 16, unless and until a Responsible Officer of the
Trustee shall have received written notice thereof from the


                                       98
<PAGE>

Company or a holder or holders of Company Senior Indebtedness with respect to
the Securities of such series or from any trustee therefor; and before the
receipt of any such written notice, the Trustee, subject to the provisions of
Article 6 of this Indenture, 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 16.6 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, any
premium or interest (including any Additional Interest) on, or any Additional
Amounts with respect to, any Security of such series), 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 that
may be received by it within two Business Days prior to such date.

      The Trustee, subject to the provisions of Article 6 of this Indenture,
shall be entitled to conclusively rely on the delivery to it of a written notice
by a Person representing himself to be a holder of Company Senior Indebtedness
with respect to the Securities of any series (or a trustee on behalf of such
holder), to establish that such notice has been given by a holder of such
Company 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 such
Company Senior Indebtedness to participate in any payment or distribution
pursuant to this Article 16, the Trustee may request such Person to furnish
evidence to the reasonable satisfaction of the Trustee as to the amount of such
Company 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 rights of such Person under this Article 16, 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.

      Upon any payment or distribution of assets of the Company referred to in
this Article 16, the Trustee and the Holders shall be entitled to rely upon any
order or decree entered by any court of competent jurisdiction in which such
insolvency, bankruptcy, receivership, liquidation, reorganization, dissolution,
winding-up or similar case or proceeding is pending, or a certificate of the
trustee in bankruptcy, liquidating trustee, custodian, receiver, assignee for
the benefit of creditors, agent or other Person making such payment or
distribution, delivered to the Trustee or to the Holders of the Securities of
any series, for the purpose of ascertaining the Persons entitled to participate
in such payment or distribution, the holders of Company Senior Indebtedness with
respect to the Securities of such series and other indebtedness of the Company,
the amount thereof or payable thereon, the amount or amounts paid or distributed
thereon and all other facts pertinent thereto or to this Article 16.

      Section 16.7. Rights of the Trustee; Holders of Company Senior
Indebtedness.

      The Trustee in its individual capacity shall be entitled to all the rights
set forth in this Article 16 in respect of any Company Senior Indebtedness with
respect to the Securities of any series at any time held by it, to the same
extent as any other holder of such Company Senior


                                       99
<PAGE>

Indebtedness, and nothing in this Indenture or any Additional Provisions shall
deprive the Trustee of any of its rights as such holder.

      With respect to the holders of Company Senior Indebtedness with respect to
the Securities of any series, the Trustee undertakes to perform or to observe
only such of its covenants and obligations as are specifically set forth in this
Article 16, and no implied covenants or obligations with respect to the holders
of such Company Senior Indebtedness shall be read into this Indenture or any
Additional Provisions against the Trustee. The Trustee shall not be deemed to
owe any fiduciary duty to the holders of such Company Senior Indebtedness and,
subject to the provisions of Article 6 of this Indenture, the Trustee shall not
be liable to any holder of such Company Senior Indebtedness if it shall pay over
or deliver to Holders of the Securities of such series, the Company or any other
Person money or assets to which any holder of such Company Senior Indebtedness
shall be entitled by virtue of this Article 16 or otherwise.

      Nothing in this Article 16 shall apply to claims of, or payments to, the
Trustee under or pursuant to Section 6.6.

      Section 16.8. Subordination May Not Be Impaired

      No right of any present or future holder of any Company 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 that any such holder may
have or otherwise be charged with.

      Without in any way limiting the generality of the foregoing paragraph, the
holders of Company Senior Indebtedness with respect to the Securities of any
series may, at any time and from time to time, without the consent of or notice
to the Trustee or the Holders of Securities of such series, without incurring
responsibility to such Holders and without impairing or releasing the
subordination provided in this Article 16 or the obligations hereunder of the
Holders of the Securities of such series to the holders of such Company 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
Company Senior Indebtedness, or otherwise amend or supplement in any manner such
Company Senior Indebtedness or any instrument evidencing the same or any
agreement under which such Company Senior Indebtedness is outstanding; (ii)
sell, exchange, release or otherwise deal with any property pledged, mortgaged
or otherwise securing such Company Senior Indebtedness; (iii) release any Person
liable in any manner for the collection of such Company Senior Indebtedness; and
(iv) exercise or refrain from exercising any rights against the Company and any
other Person.

                                   ARTICLE 17

                           GUARANTEE AND INDEMNITY

      Section 17.1. The Guarantee.

      The Guarantor hereby unconditionally guarantees to each Holder of a
Security authenticated and delivered by the Trustee the due and punctual payment
of the principal of, any premium and interest (including any Additional
Interest) on, any Additional Amounts, and, if applicable, any Additional Sums
with respect to such Security and the due and punctual payment of the sinking
fund payments (if any) provided for pursuant to the terms of such Security, when
and as the same shall become due and payable, whether at maturity, by
acceleration, redemption, repayment or otherwise, in accordance with the terms
of such Security and of this Indenture. In case of the failure of the Company
punctually to pay any such principal, premium, interest (including any
Additional Interest), Additional Amounts, Additional Sums or sinking fund
payment, the Guarantor hereby agrees to cause any such payment to be made
punctually when and as the same shall become due and payable, whether at
maturity, upon acceleration, redemption, repayment or otherwise, and as if such
payment were made by the Company.

      Section 17.2. Net Payments.

      All payments of principal of and premium, if any, interest (including any
Additional Interest) and any other amounts on, or in respect of, the Securities
of any series or any Coupon appertaining thereto shall be made by the Guarantor
without withholding or deduction at source for, or on account of, any present or
future taxes, fees, duties, assessments or governmental charges of whatever
nature imposed or levied by or on behalf of the Cayman Islands or Bermuda (each,
a "taxing jurisdiction") or any political subdivision or taxing authority
thereof or therein, unless such taxes, fees, duties, assessments or governmental
charges are required to be withheld or deducted by (i) the laws (or any
regulations or ruling promulgated thereunder) of a taxing jurisdiction or any
political subdivision or taxing authority thereof or therein or (ii) an official
position regarding the application, administration, interpretation or
enforcement of any such laws, regulations or rulings (including, without
limitation, a holding by a court of competent jurisdiction or by a taxing
authority in a taxing jurisdiction or any political subdivision thereof). If a
withholding or deduction at source is required, the Guarantor shall, subject to
certain limitations and exceptions set forth below, pay to the Holder of any
such Security or any Coupon appertaining thereto such Additional Amounts as may
be necessary so that every net payment of principal, premium, if any, interest
or any other amount made to such Holder, after such withholding or deduction,
shall not be less than the amount provided for in such Security, any Coupons
appertaining thereto and this Indenture to be then due and payable; provided,
however, that the Guarantor shall not be required to make payment of such
Additional Amounts for or on account of:

           (1) any tax, fee, duty, assessment or governmental charge of
      whatever nature which would not have been imposed but for the fact that
      such Holder: (A) was a resident, domiciliary or national of, or engaged in
      business or maintained a permanent


                                      101
<PAGE>

      establishment or was physically present in, the relevant taxing
      jurisdiction or any political subdivision thereof or otherwise had some
      connection with the relevant taxing jurisdiction other than by reason of
      the mere ownership of, or receipt of payment under, such Security; (B)
      presented such Security for payment in the relevant taxing jurisdiction or
      any political subdivision thereof, unless such Security could not have
      been presented for payment elsewhere; or (C) presented such Security more
      than thirty (30) days after the date on which the payment in respect of
      such Security first became due and payable or provided for, whichever is
      later, except to the extent that the Holder would have been entitled to
      such Additional Amounts if it had presented such Security for payment on
      any day within such period of thirty (30) days;

            (2) any estate, inheritance, gift, sale, transfer, personal property
      or similar tax, assessment or other governmental charge;

            (3) any tax, assessment or other governmental charge that is imposed
      or withheld by reason of the failure by the Holder or the beneficial owner
      of such Security to comply with any reasonable request by the Guarantor
      addressed to the Holder within 90 days of such request (A) to provide
      information concerning the nationality, residence or identity of the
      Holder or such beneficial owner or (B) to make any declaration or other
      similar claim or satisfy any information or reporting requirement, which,
      in the case of (A) or (B), is required or imposed by statute, treaty,
      regulation or administrative practice of the relevant taxing jurisdiction
      or any political subdivision thereof as a precondition to exemption from
      all or part of such tax, assessment or other governmental charge; or

            (4) any combination of items (1), (2) and (3);

nor shall Additional Amounts be paid with respect to any payment of the
principal of, or premium, if any, interest or any other amounts on, any such
Security to any Holder who is a fiduciary or partnership or other than the sole
beneficial owner of such Security to the extent such payment would be required
by the laws of the relevant taxing jurisdiction (or any political subdivision or
relevant taxing authority thereof or therein) to be included in the income for
tax purposes of a beneficiary or partner or settlor with respect to such
fiduciary or a member of such partnership or a beneficial owner who would not
have been entitled to such Additional Amounts had it been the Holder of the
Security.

      Whenever in this Indenture there is mentioned, in any context, the payment
of the principal of or any premium, interest or any other amounts on, or in
respect of, any Security of any series or any Coupon or the net proceeds
received on the sale or exchange of any Security of any series, such mention
shall be deemed to include mention of the payment of Additional Amounts provided
by the terms of such series established hereby or pursuant hereto to the extent
that, in such context, Additional Amounts are, were or would be payable in
respect thereof pursuant to such terms, and express mention of the payment of
Additional Amounts (if applicable) in any provision hereof shall not be
construed as excluding the payment of Additional Amounts in those provisions
hereof where such express mention is not made.


                                      102
<PAGE>

      Except as otherwise provided in or pursuant to this Indenture or the
Securities of the applicable series, at least 10 days prior to the first
Interest Payment Date with respect to a series of Securities (or if the
Securities of such series shall not bear interest prior to Maturity, the first
day on which a payment of principal is made), and at least 10 days prior to each
date of payment of principal or interest if there has been any change with
respect to the matters set forth in the below-mentioned Guarantor's Officer's
Certificate, the Guarantor shall furnish to the Trustee and the principal Paying
Agent or Paying Agents, if other than the Trustee, a Guarantor's Officer's
Certificate instructing the Trustee and such Paying Agent or Paying Agents
whether such payment of principal of and premium, if any, interest or any other
amounts on the Securities of such series shall be made to Holders of Securities
of such series or the Coupons appertaining thereto without withholding for or on
account of any tax, fee, duty, assessment or other governmental charge described
in this Section 17.2. If any such withholding shall be required, then such
Guarantor's Officer's Certificate shall specify by taxing jurisdiction the
amount, if any, required to be withheld on such payments to such Holders of
Securities or Coupons, and the Guarantor agrees to pay to the Trustee or such
Paying Agent the Additional Amounts required by this Section 17.2. The Guarantor
covenants to indemnify the Trustee and any Paying Agent for, and to hold them
harmless against, any loss, liability or expense reasonably incurred without
negligence or bad faith on their part arising out of or in connection with
actions taken or omitted by any of them in reliance on any Guarantor's Officer's
Certificate furnished pursuant to this Section 17.2.

      Section 17.3. Guarantee Unconditional, etc.

      The Guarantor hereby agrees that its obligations hereunder shall be as
principal and not merely as surety, and shall be absolute, irrevocable and
unconditional, irrespective of, and shall be unaffected by, any invalidity,
irregularity or unenforceability of any Security or this Indenture, any failure
to enforce the provisions of any Security or this Indenture, or any waiver,
modification, consent or indulgence granted with respect thereto by the Holder
of such Security or the Trustee, the recovery of any judgment against the
Company or any action to enforce the same, or any other circumstances which may
otherwise constitute a legal or equitable discharge of a surety or guarantor.
The Guarantor hereby waives diligence, presentment, demand of payment, filing of
claims with a court in the event of merger, insolvency or bankruptcy of the
Company, any right to require a proceeding first against the Company, protest or
notice with respect to any such Security or the Indebtedness evidenced thereby
and all demands whatsoever, and covenants that this Guarantee will not be
discharged except by payment in full of the principal of, any premium and
interest (including any Additional Interest) on, and any Additional Amounts,
and, if applicable, any Additional Sums and sinking fund payments required with
respect to, the Securities and the complete performance of all other obligations
contained in the Securities. The Guarantor further agrees, to the fullest extent
that it lawfully may do so, that, as between the Guarantor, on the one hand, and
the Holders and the Trustee, on the other hand, the Maturity of the obligations
guaranteed hereby may be accelerated as provided in Section 5.2 hereof for the
purposes of this Guarantee, notwithstanding any stay, injunction or prohibition
extant under any bankruptcy, insolvency, reorganization or other similar law of
any jurisdiction preventing such acceleration in respect of the obligations
guaranteed hereby.

<PAGE>

      Section 17.4. Reinstatement.

      This Guarantee shall continue to be effective or be reinstated, as the
case may be, if at any time payment on any Security, in whole or in part, is
rescinded or must otherwise be restored to the Company or the Guarantor upon the
bankruptcy, liquidation or reorganization of the Company or otherwise.

      Section 17.5. Subrogation.

      The Guarantor shall be subrogated to all rights of the Holder of any
Security against the Company in respect of any amounts paid to such Holder by
the Guarantor pursuant to the provisions of this Guarantee; provided, however,
that the Guarantor shall not be entitled to enforce, or to receive any payments
arising out of or based upon, such right of subrogation until the principal of,
any premium and interest (including any Additional Interest) on, and any
Additional Amounts and, if applicable, any Additional Sums and sinking fund
payments required with respect to, all Securities shall have been paid in full.

      Section 17.6. Indemnity.

      As a separate and alternative stipulation, the Guarantor unconditionally
and irrevocably agrees that any sum expressed to be payable by the Company under
this Indenture, the Securities or the Coupons but which is for any reason
(whether or not now known or becoming known to the Company, the Guarantor, the
Trustee or any Holder of any Security or Coupon) not recoverable from the
Guarantor on the basis of a guarantee will nevertheless be recoverable from it
as if it were the sole principal debtor and will be paid by it to the Trustee on
demand. This indemnity constitutes a separate and independent obligation from
the other obligations in this Indenture, gives rise to a separate and
independent cause of action and will apply irrespective of any indulgence
granted by the Trustee or any Holder of any Security or Coupon.

                                   ARTICLE 18

                          SUBORDINATION OF GUARANTEE

      Section 18.1. Agreement to Subordinate Guarantee.

      The Guarantor covenants and agrees, and each Holder of Securities issued
hereunder and under any Additional Provisions, by such Holder's acceptance
thereof likewise covenants and agrees, that all Securities shall be issued
subject to the provisions of this Article 18; and each Holder of a Security,
whether upon original issue or upon transfer or assignment thereof, accepts and
agrees to be bound by such provisions.

      The payment by the Guarantor pursuant to the Guarantee of the principal
of, any premium and interest (including any Additional Interest) on, any
Additional Amounts and, if applicable, any Additional Sums with respect to all
Securities of each series issued hereunder and under any Additional Provisions
shall, to the extent and in the manner hereinafter set forth,


                                      104
<PAGE>

be subordinate in right of payment to the prior payment in full of all Guarantor
Senior Indebtedness with respect to such series, whether outstanding at the date
of this Indenture or thereafter incurred.

      No provision of this Article 18 shall prevent the occurrence of any
default or Event of Default hereunder.

      Section 18.2. Default on Guarantor Senior Indebtedness.

      In the event and during the continuation of any default by the Guarantor
in the payment of principal, premium, interest (including any Additional
Interest) or any other amount due on any Guarantor Senior Indebtedness with
respect to the Securities of any series, or in the event that the maturity of
any Guarantor Senior Indebtedness with respect to the Securities of any series
has been accelerated because of a default, then, in either case, no payment
shall be made by the Guarantor pursuant to the Guarantee with respect to the
principal (including redemption and sinking fund payments) of, any premium or
interest (including any Additional Interest) on, or any Additional Amounts or,
if applicable, Additional Sums with respect to, the Securities of such series.

      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 18.2, such payment shall be held in trust for the
benefit of, and shall be paid over or delivered to, the holders of such
Guarantor Senior Indebtedness or their respective representatives, or to the
trustee or trustees under any indenture pursuant to which any of such Guarantor
Senior Indebtedness may have been issued, as their respective interests may
appear, but only to the extent that the holders of such Guarantor 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 such Guarantor Senior Indebtedness and only the amounts specified
in such notice to the Trustee shall be paid to the holders of such Guarantor
Senior Indebtedness.

      Section 18.3. Liquidation; Dissolution; Bankruptcy.

      Upon any payment by the Guarantor or distribution of assets of the
Guarantor of any kind or character, whether in cash, property or securities, to
creditors upon any dissolution, winding-up, liquidation or reorganization of the
Guarantor, whether voluntary or involuntary, or in bankruptcy, insolvency,
receivership or other proceedings, all amounts due upon all Guarantor Senior
Indebtedness with respect to the Securities of any series shall first be paid in
full, or payment thereof provided for in money in accordance with its terms,
before any payment is made by the Guarantor pursuant to the Guarantee on account
of the principal of, premium or interest (including any Additional Interest) on,
or Additional Amounts or, if applicable, Additional Sums with respect to, the
Securities of such series; and upon any such dissolution, winding-up,
liquidation or reorganization, or in any such bankruptcy, insolvency,
receivership or other proceeding, any payment by the Guarantor, or distribution
of assets of the Guarantor of any kind or character, whether in cash, property
or securities, to which the Holders or the Trustee would


                                      105
<PAGE>

be entitled to receive from the Guarantor, except for the provisions of this
Article 18, shall be paid by the Guarantor or by any receiver, trustee in
bankruptcy, liquidating trustee, agent or other Person making such payment or
distribution, or by the Holders or by the Trustee under this Indenture if
received by them or it, directly to the holders of such Guarantor Senior
Indebtedness (pro rata to such holders on the basis of the respective amounts of
such Guarantor Senior Indebtedness held by such holders, as calculated by the
Guarantor) or their representative or representatives, or to the trustee or
trustees under any indenture pursuant to which any instruments evidencing such
Guarantor Senior Indebtedness may have been issued, as their respective
interests may appear, to the extent necessary to pay such Guarantor 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 Guarantor
Senior Indebtedness, before any payment or distribution is made pursuant to the
Guarantee to the Holders of the Securities of such series or to the Trustee.

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

      For purposes of this Article 18, the words "cash, property or securities"
shall not be deemed to include shares of stock of the Guarantor as reorganized
or readjusted, or securities of the Guarantor 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 18 with respect to
the Guarantee in respect of any series of Securities to the payment of all
Guarantor Senior Indebtedness with respect to the Securities of such series that
may at the time be outstanding, provided that (i) such Guarantor 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
Guarantor Senior Indebtedness are not, without the consent of such holders,
altered by such reorganization or readjustment. The consolidation of the
Guarantor with, or the merger of the Guarantor into, another Person or the
liquidation or dissolution of the Guarantor following the conveyance, transfer
or lease of its property as an entirety, or substantially as an entirety, to
another Person upon the terms and conditions provided for in Sections 8.3 and
8.4 of this Indenture shall not be deemed a dissolution, winding-up, liquidation
or reorganization for the purposes of this Section 18.3 if such other Person
shall, as a part of such consolidation, merger, conveyance or transfer, comply
with the conditions stated in Sections 8.3 and 8.4 of this


                                      106
<PAGE>

Indenture. Nothing in Section 18.2 or in this Section 18.3 shall apply to claims
of, or payments to, the Trustee under or pursuant to Section 6.6 of this
Indenture.

      Section 18.4. Subrogation.

      Subject to the payment in full of all Guarantor Senior Indebtedness with
respect to the Securities of any series, the rights of the Holders of the
Securities of such series shall be subrogated to the rights of the holders of
such Guarantor Senior Indebtedness to receive payments or distributions of cash,
property or securities of the Guarantor applicable to such Guarantor Senior
Indebtedness until the principal of, any premium and interest (including any
Additional Interest) on, and any Additional Amounts or, if applicable,
Additional Sums with respect to, the Securities of such series shall be paid in
full; and, for the purposes of such subrogation, no payments or distributions to
the holders of such Guarantor Senior Indebtedness of any cash, property or
securities to which the Holders or the Trustee would be entitled except for the
provisions of this Article 18, and no payment over pursuant to the provisions of
this Article 18 to or for the benefit of the holders of such Guarantor Senior
Indebtedness by Holders of the Securities of such series or the Trustee, shall,
as between the Guarantor, its creditors other than holders of such Guarantor
Senior Indebtedness, and the Holders of the Securities of such series, be deemed
to be a payment by the Guarantor to or on account of such Guarantor Senior
Indebtedness. It is understood that the provisions of this Article 18 are and
are intended solely for the purposes of defining the relative rights of the
Holders of the Securities of each series, on the one hand, and the holders of
such Guarantor Senior Indebtedness with respect to the Securities of such series
on the other hand.

      Nothing contained in this Article 18 or elsewhere in this Indenture, any
Additional Provisions or in the Securities of any series is intended to or shall
impair, as between the Guarantor, its creditors other than the holders of
Guarantor Senior Indebtedness with respect to the Securities of such series, and
the Holders of the Securities of such series, the obligation of the Guarantor,
which is absolute and unconditional, to pay to the Holders of the Securities of
such series pursuant to the Guarantee the principal of, any premium and interest
(including any Additional Interest) on, and any Additional Amounts or, if
applicable, Additional Sums with respect to, the Securities of such series 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
Securities of such series and creditors of the Guarantor, other than the holders
of such Guarantor Senior Indebtedness, nor shall anything herein or therein
prevent the Trustee or the Holder of any Security of such series from exercising
all remedies otherwise permitted by applicable law upon default under this
Indenture, subject to the rights, if any, under this Article 18 of the holders
of such Guarantor Senior Indebtedness in respect of cash, property or securities
of the Guarantor, as the case may be, received upon the exercise of any such
remedy.

      Upon any payment or distribution of assets of the Guarantor referred to in
this Article 18, the Trustee, subject to the provisions of Article 6 of this
Indenture, and the Holders shall be entitled to conclusively rely upon any order
or decree made by any court of competent jurisdiction in which such dissolution,
winding-up, liquidation or reorganization proceedings are


                                      107
<PAGE>

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 Securities of any series, for the purposes
of ascertaining the Persons entitled to participate in such distribution, the
holders of Guarantor Senior Indebtedness with respect to the Securities of such
series and other indebtedness of the Guarantor, 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 18.

      Section 18.5. Trustee to Effectuate Subordination.

      Each Holder of Securities 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 18 and appoints the Trustee such Holder's attorney-in-fact for any and
all such purposes.

      Section 18.6. Notice by the Guarantor.

      The Guarantor shall give prompt written notice to a Responsible Officer of
the Trustee of any fact known to the Guarantor that would prohibit the making of
any payment of monies to or by the Trustee in respect of the Securities of any
series pursuant to the provisions of this Article 18. Notwithstanding the
provisions of this Article 18 or any other provision of this Indenture or any
Additional Provisions, the Trustee shall not be charged with knowledge of the
existence of any facts that would prohibit the making of any payment of monies
to or by the Trustee in respect of the Securities of any series pursuant to the
provisions of this Article 18, unless and until a Responsible Officer of the
Trustee shall have received written notice thereof from the Guarantor or a
holder or holders of Guarantor Senior Indebtedness with respect to the
Securities of such series or from any trustee therefor; and before the receipt
of any such written notice, the Trustee, subject to the provisions of Article 6
of this Indenture, 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 18.6 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 pursuant to the Guarantee of the
principal of, any premium or interest (including any Additional Interest) on, or
any Additional Amounts or, if applicable, Additional Sums with respect to, any
Security of such series), 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 that may be received by it
within two Business Days prior to such date.

      The Trustee, subject to the provisions of Article 6 of this Indenture,
shall be entitled to conclusively rely on the delivery to it of a written notice
by a Person representing himself to be a holder of Guarantor Senior Indebtedness
with respect to the Securities of any series (or a trustee on behalf of such
holder), to establish that such notice has been given by a holder of such
Guarantor 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 such
Guarantor Senior Indebtedness to participate in any payment or


                                      108

distribution pursuant to this Article 18, the Trustee may request such Person to
furnish evidence to the reasonable satisfaction of the Trustee as to the amount
of such Guarantor 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 rights of such Person under this Article 18, 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.

      Upon any payment or distribution of assets of the Guarantor referred to in
this Article 18, the Trustee and the Holders shall be entitled to rely upon any
order or decree entered by any court of competent jurisdiction in which such
insolvency, bankruptcy, receivership, liquidation, reorganization, dissolution,
winding-up or similar case or proceeding is pending, or a certificate of the
trustee in bankruptcy, liquidating trustee, custodian, receiver, assignee for
the benefit of creditors, agent or other Person making such payment or
distribution, delivered to the Trustee or to the Holders of the Securities of
any series, for the purpose of ascertaining the Persons entitled to participate
in such payment or distribution, the holders of Guarantor Senior Indebtedness
with respect to the Securities of such series and other indebtedness of the
Guarantor, the amount thereof or payable thereon, the amount or amounts paid or
distributed thereon and all other facts pertinent thereto or to this Article 18.

      Section 18.7. Rights of the Trustee; Holders of Guarantor Senior
Indebtedness.

      The Trustee in its individual capacity shall be entitled to all the rights
set forth in this Article 18 in respect of any Guarantor Senior Indebtedness
with respect to the Securities of any series at any time held by it, to the same
extent as any other holder of such Guarantor Senior Indebtedness, and nothing in
this Indenture or any Additional Provisions shall deprive the Trustee of any of
its rights as such holder.

      With respect to the holders of Guarantor Senior Indebtedness with respect
to the Securities of any series, the Trustee undertakes to perform or to observe
only such of its covenants and obligations as are specifically set forth in this
Article 18, and no implied covenants or obligations with respect to the holders
of such Guarantor Senior Indebtedness shall be read into this Indenture or any
Additional Provisions against the Trustee. The Trustee shall not be deemed to
owe any fiduciary duty to the holders of such Guarantor Senior Indebtedness and,
subject to the provisions of Article 6 of this Indenture, the Trustee shall not
be liable to any holder of such Guarantor Senior Indebtedness if it shall pay
over or deliver to Holders of the Securities of such series, the Guarantor or
any other Person money or assets to which any holder of such Guarantor Senior
Indebtedness shall be entitled by virtue of this Article 18 or otherwise.

      Nothing in this Article 18 shall apply to claims of, or payments to, the
Trustee under or pursuant to Section 6.6.

      Section 18.8. Subordination May Not Be Impaired.

      No right of any present or future holder of any Guarantor Senior
Indebtedness to enforce subordination as herein provided shall at any time in
any way be prejudiced or impaired by any


                                      109
<PAGE>

act or failure to act on the part of the Guarantor, or by any act or failure to
act, in good faith, by any such holder, or by any noncompliance by the Guarantor
with the terms, provisions and covenants of this Indenture, regardless of any
knowledge thereof that any such holder may have or otherwise be charged with.

      Without in any way limiting the generality of the foregoing paragraph, the
holders of Guarantor Senior Indebtedness with respect to the Securities of any
series may, at any time and from time to time, without the consent of or notice
to the Trustee or the Holders of Securities of such series, without incurring
responsibility to such Holders and without impairing or releasing the
subordination provided in this Article 18 or the obligations hereunder of the
Holders of the Securities of such series to the holders of such Guarantor 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
Guarantor Senior Indebtedness, or otherwise amend or supplement in any manner
such Guarantor Senior Indebtedness or any instrument evidencing the same or any
agreement under which such Guarantor Senior Indebtedness is outstanding; (ii)
sell, exchange, release or otherwise deal with any property pledged, mortgaged
or otherwise securing such Guarantor Senior Indebtedness; (iii) release any
Person liable in any manner for the collection of such Guarantor Senior
Indebtedness; and (iv) exercise or refrain from exercising any rights against
the Guarantor and any other Person.

hereby agree as follows:

     1.   The trust created hereby shall be known as "ACE Capital Trust I" (the

herein, may conduct the business of the Trust, make and execute contracts, and
sue and be sued.

     2.   The Depositor hereby assigns, transfers, conveys and sets over to the

It is the intention of the parties hereto that the Trust created hereby

constitute the governing instrument of the Trust.  The Trustees are hereby
authorized and directed to execute and file a certificate of trust with the

     3.   The Depositor and the Trustees will enter into an amended and restated
Trust Agreement satisfactory to each such party to provide for the contemplated
operation of the Trust created hereby and the issuance of the Preferred
Securities and Common Securities referred to therein.  Prior to the execution
and delivery of such amended and restated Trust Agreement, the Trustees shall
not have any duty or obligation hereunder or with respect of the trust estate,
except as otherwise required by applicable law or as may be necessary to obtain
prior to such execution and delivery any licenses, consents or approvals
required by applicable law or otherwise. Notwithstanding the foregoing, the
Trustees may take all actions deemed proper as are necessary to effect the
transactions contemplated herein.

     4.   The Depositor, as depositor of the Trust, is hereby authorized, in its
discretion, (i) to prepare and file with the Securities and Exchange Commission

Statement"), including all pre-effective and post-effective amendments thereto,
relating to the registration under the Securities Act of 1933, as amended (the

prospectus or prospectus or supplement thereto relating
<PAGE>

to the Preferred Securities of the Trust required to be filed pursuant to the
1933 Act, and (c) a Registration Statement on Form 8-A or other appropriate form
(the "1934 Act Registration Statement"), including all pre-effective and post-
effective amendments thereto, relating to the registration of the Preferred
Securities of the Trust under the Securities Exchange Act of 1934, as amended;
(ii) if and at such time as determined by the Depositor, to file with the New
York Stock Exchange or other exchange, or the National Association of Securities
Dealers ("NASD"), and execute on behalf of the Trust a listing application and
all other applications, statements, certificates, agreements and other
instruments as shall be necessary or desirable to cause the Preferred Securities
of the Trust to be listed on the New York Stock Exchange or such other exchange,
or the NASD's Nasdaq National Market; (iii) to file and execute on behalf of the
Trust, such applications, reports, surety bonds, irrevocable consents,
appointments of attorney for service of process and other papers and documents
that shall be necessary or desirable to register the Preferred Securities of the
Trust under the securities or "Blue Sky" laws of such jurisdictions as the
Depositor, on behalf of the Trust, may deem necessary or desirable; (iv) to
execute and deliver letters or documents to, or instruments for filing with, a
depository relating to the Preferred Securities of the Trust; and (v) to
execute, deliver and perform on behalf of the Trust an underwriting agreement
with one or more underwriters relating to the offering of the Preferred

     In the event that any filing referred to in this Section 4 is required by
the rules and regulations of the Commission, the New York Stock Exchange or
other exchange, NASD, or state securities or "Blue Sky" laws to be executed on
behalf of the Trust by the Trustees, the Trustees, in their capacity as trustees
of the Trust, are hereby authorized to join in any such filing and to execute on
behalf of the Trust any and all of the foregoing, it being understood that the
Trustees, in their capacity as trustees of the Trust, shall not be required to
join in any such filing or execute on behalf of the Trust any such document
unless required by the rules and regulations of the Commission, the New York
Stock Exchange or other exchange, NASD, or state securities or "Blue Sky" laws.

     5.   This Trust Agreement may be executed in one or more counterparts.

     6.   The number of trustees of the Trust initially shall be three and
thereafter the number of trustees of the Trust shall be such number as shall be
fixed from time to time by a written instrument signed by the Depositor which
may increase or decrease the number of trustees of the Trust; provided, however,
that to the extent required by the Business Trust Act, one trustee of the Trust
shall either be a natural person who is a resident of the State of Delaware or,
if not a natural person, an entity which has its principal place of business in
the State of Delaware and otherwise meets the requirements of applicable
Delaware law.  Subject to the foregoing, the Depositor is entitled to appoint or
remove without cause any trustee of the Trust at any time. Any trustee of the
Trust may resign upon thirty days' prior notice to the Depositor.

     7.   Bank One Delaware, Inc., in its capacity as Trustee, shall not have
<PAGE>

the powers or duties of the Trustees set forth herein (except as may be required
under the Business Trust Act) and shall be a trustee hereunder for the sole and
limited purpose of fulfilling the requirements of Section 3807(a) of the
Business Trust Act.

     8.   The Trust may be dissolved and terminated before the issuance of the
Preferred Securities at the election of the Depositor.

     9.   This Trust Agreement shall be governed by, and construed in accordance
with, the laws of the State of Delaware (without regard to conflict of laws
principles).

     IN WITNESS WHEREOF, the parties hereto have caused this Trust Agreement to
be duly executed as of the day and year first above written.

                                TRUST AGREEMENT
                                       OF

collectively referred to as the "Trustees").  The Depositor and the Trustees
hereby agree as follows:

     1.   The trust created hereby shall be known as "ACE Capital Trust II" (the
"Trust"), in which name the Trustees or the Depositor, to the extent provided
herein, may conduct the business of the Trust, make and execute contracts, and
sue and be sued.

     2.   The Depositor hereby assigns, transfers, conveys and sets over to the
Trust the sum of $10.  Such amount shall constitute the initial trust estate.
It is the intention of the parties hereto that the Trust created hereby
constitute a business trust under Chapter 38 of Title 12 of the Delaware Code,
12 Del. C. (S) 3801, et seq. (the "Business Trust Act"), and that this document

constitute the governing instrument of the Trust.  The Trustees are hereby
authorized and directed to execute and file a certificate of trust with the
Delaware Secretary of State in such form as the Trustees may approve.

     3.   The Depositor and the Trustees will enter into an amended and restated
Trust Agreement satisfactory to each such party to provide for the contemplated
operation of the Trust created hereby and the issuance of the Preferred
Securities and Common Securities referred to therein.  Prior to the execution
and delivery of such amended and restated Trust Agreement, the Trustees shall
not have any duty or obligation hereunder or with respect of the trust estate,
except as otherwise required by applicable law or as may be necessary to obtain
prior to such execution and delivery any licenses, consents or approvals
required by applicable law or otherwise. Notwithstanding the foregoing, the
Trustees may take all actions deemed proper as are necessary to effect the
transactions contemplated herein.

     4.   The Depositor, as depositor of the Trust, is hereby authorized, in its
discretion, (i) to prepare and file with the Securities and Exchange Commission
(the "Commission") and to execute, in the case of the 1933 Act Registration
Statement and 1934 Act Registration Statement (each as herein defined), on
behalf of the Trust, (a) a Registration Statement  (the "1933 Act Registration
Statement"), including all pre-effective and post-effective amendments thereto,
relating to the registration under the Securities Act of 1933, as amended (the
"1933 Act"), of the Preferred Securities of the Trust, (b) any preliminary
prospectus or prospectus or supplement thereto relating
<PAGE>

to the Preferred Securities of the Trust required to be filed pursuant to the
1933 Act, and (c) a Registration Statement on Form 8-A or other appropriate form
(the "1934 Act Registration Statement"), including all pre-effective and post-
effective amendments thereto, relating to the registration of the Preferred
Securities of the Trust under the Securities Exchange Act of 1934, as amended;
(ii) if and at such time as determined by the Depositor, to file with the New
York Stock Exchange or other exchange, or the National Association of Securities
Dealers ("NASD"), and execute on behalf of the Trust a listing application and
all other applications, statements, certificates, agreements and other
instruments as shall be necessary or desirable to cause the Preferred Securities
of the Trust to be listed on the New York Stock Exchange or such other exchange,
or the NASD's Nasdaq National Market; (iii) to file and execute on behalf of the
Trust, such applications, reports, surety bonds, irrevocable consents,
appointments of attorney for service of process and other papers and documents
that shall be necessary or desirable to register the Preferred Securities of the
Trust under the securities or "Blue Sky" laws of such jurisdictions as the
Depositor, on behalf of the Trust, may deem necessary or desirable; (iv) to
execute and deliver letters or documents to, or instruments for filing with, a
depository relating to the Preferred Securities of the Trust; and (v) to
execute, deliver and perform on behalf of the Trust an underwriting agreement
with one or more underwriters relating to the offering of the Preferred
Securities of the Trust.

     In the event that any filing referred to in this Section 4 is required by
the rules and regulations of the Commission, the New York Stock Exchange or
other exchange, NASD, or state securities or "Blue Sky" laws to be executed on
behalf of the Trust by the Trustees, the Trustees, in their capacity as trustees
of the Trust, are hereby authorized to join in any such filing and to execute on
behalf of the Trust any and all of the foregoing, it being understood that the
Trustees, in their capacity as trustees of the Trust, shall not be required to
join in any such filing or execute on behalf of the Trust any such document
unless required by the rules and regulations of the Commission, the New York
Stock Exchange or other exchange, NASD, or state securities or "Blue Sky" laws.

     5.   This Trust Agreement may be executed in one or more counterparts.

     6.   The number of trustees of the Trust initially shall be three and
thereafter the number of trustees of the Trust shall be such number as shall be
fixed from time to time by a written instrument signed by the Depositor which
may increase or decrease the number of trustees of the Trust; provided, however,
that to the extent required by the Business Trust Act, one trustee of the Trust
shall either be a natural person who is a resident of the State of Delaware or,
if not a natural person, an entity which has its principal place of business in
the State of Delaware and otherwise meets the requirements of applicable
Delaware law.  Subject to the foregoing, the Depositor is entitled to appoint or
remove without cause any trustee of the Trust at any time. Any trustee of the
Trust may resign upon thirty days' prior notice to the Depositor.

     7.   Bank One Delaware, Inc., in its capacity as Trustee, shall not have
the
<PAGE>

powers or duties of the Trustees set forth herein (except as may be required
under the Business Trust Act) and shall be a trustee hereunder for the sole and
limited purpose of fulfilling the requirements of Section 3807(a) of the
Business Trust Act.

     8.   The Trust may be dissolved and terminated before the issuance of the
Preferred Securities at the election of the Depositor.

     9.   This Trust Agreement shall be governed by, and construed in accordance
with, the laws of the State of Delaware (without regard to conflict of laws
principles).

     IN WITNESS WHEREOF, the parties hereto have caused this Trust Agreement to
be duly executed as of the day and year first above written.

                      CERTAIN TERMS OF THE TRUST SECURITIES

SECTION 4.1  DISTRIBUTIONS.

     (a) Distributions on the Trust Securities shall be cumulative, and will
accumulate whether or not there are funds of the Trust available for the payment
of Distributions. Distributions shall accrue from __________, ____, and shall be
payable quarterly in arrears on _________, _______, ______ and ________ of each
year, commencing on __________, _____, except as otherwise described below. The
Debenture Issuer has the right under the Indenture, at any time and from time to
time, to defer payments of interest for such period or periods as may be
specified with respect to the Debentures (each, an "Extension Period"), on the
terms and conditions specified in the Indenture. As a consequence of such
deferral, Distributions will also be deferred. Despite such deferral, quarterly
Distributions will continue to accumulate at the rate set forth in paragraph (b)
of this Section 4.1, together with additional distributions thereon (to the
extent permitted by applicable law) at the rate at which Additional Interest is
then accruing on the Debentures, compounded quarterly during any such Extension
Period. If any date on which a Distribution is otherwise payable on the Trust
Securities is not a Business Day, then the payment of such Distribution shall be
made on the next succeeding day that is a Business Day (and without any
additional distributions or other payment in respect of any such delay), except
that, if such Business Day is in the next succeeding calendar year, payment of
such Distribution shall be made on the immediately preceding Business Day, in
each case with the same force and effect as if made on the date such payment was
originally payable (each date on which distributions are payable in accordance
with this Section 4.1(a), a "Distribution Date").


                                       16
<PAGE>

     (b) The Trust Securities represent undivided beneficial interests in the
Trust Property, and, as a practical matter, the Distributions on the Trust
Securities shall be payable at a rate of __% per annum of the Liquidation Amount
of the Trust Securities. The term "Distributions" as used herein includes such
cash distributions and any accumulated or additional distributions that are
payable hereunder unless otherwise stated. The amount of Distributions payable
for any full or partial period shall be computed on the basis of a 360-day year
of twelve 30-day months. The amount of Distributions payable for any period
shall include Additional Amounts, if any.

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

     (d) Distributions on the Trust Securities with respect to a Distribution
Date shall be payable to the Holders thereof as they appear on the Securities
Register at the close of business on the relevant record date, which, as long as
the Preferred Securities remain in book-entry only form, shall be the date one
Business Day immediately preceding such Distribution Date. The relevant record
dates for the Common Securities shall be the same record dates as for the
Preferred Securities. If the Preferred Securities shall not continue to remain
in book-entry only form or are not in book-entry only form at issuance, the
relevant record dates for the Preferred Securities shall be the date 15 days
prior to the relevant Distribution Date, which Distribution Dates shall
correspond to the interest payment dates on the Debentures. Distributions
payable on any Trust Securities that are not punctually paid on any Distribution
Date, as a result of the Debenture Issuer (or the Debenture Guarantor on its
behalf) having failed to make an interest payment under the 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 for determining
Debentureholders entitled to such defaulted interest established in accordance
with the Indenture.

     (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 among the Holders of the Trust Securities. A reference
herein 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, a Debenture Event of Default 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.

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

     (d) If the Property Trustee gives a notice of redemption (which notice
shall be irrevocable) in respect of any Preferred Securities, then, by 12:00
noon, New York City time, on the Redemption Date, subject to Section 4.2(c), the
Property Trustee will, so long as the Preferred Securities are in
book-entry-only form, irrevocably deposit with the Clearing Agency for the
Preferred Securities funds sufficient to pay the applicable Redemption Price and
will give such Clearing Agency irrevocable instructions and authority to pay the
Redemption Price to the relevant Persons' accounts at such Clearing Agency on
the applicable Redemption Date. If the Preferred Securities are no longer in
book-entry-only form, and in the case of the Common Securities, the Property
Trustee, subject to Section 4.2(c), will irrevocably deposit with the Paying
Agent funds sufficient to pay the applicable Redemption Price and will give the
Paying Agent irrevocable instructions and authority to pay the Redemption Price
to the Holders thereof upon surrender of their Trust Securities Certificates.
Notwithstanding the foregoing, Distributions payable on or prior to the
Redemption Date for any Trust Securities called for redemption shall be payable
to the Holders of such Trust Securities as they appear on the Securities
Register for the Trust Securities


                                       18

on the relevant record dates for the related Distribution Dates. If notice of
redemption shall have been given and funds deposited as required, then
immediately prior to the close of business on the date of such deposit, all
rights of Securityholders holding Trust Securities so called for redemption will
cease, except the right of such Securityholders to receive the Redemption Price
and any Distributions payable on or prior to the Redemption Date, but without
interest, and such Securities will cease to be outstanding. In the event that
any date on which any Redemption Price is payable is not a Business Day, then
payment of the Redemption Price payable on such date will be made on the next
succeeding day that is a Business Day (and without any interest or other payment
in respect of any such delay), except that, if such Business Day falls in the
next calendar year, such payment will be made on the immediately preceding
Business Day, in each case, with the same force and effect as if made on such
date. In the event that payment of the Redemption Price in respect of any Trust
Securities called for redemption is improperly withheld or refused and not paid
either by the Trust or by the Preferred Securities Guarantor pursuant to the
Guarantee, Distributions on such Trust Securities will continue to accrue, at
the then applicable rate, from the Redemption Date originally established by the
Trust for such Trust Securities to the date such Redemption Price is actually
paid, in which case the actual payment date will be the date fixed for
redemption for purposes of calculating the Redemption Price.

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

     (f) Subject to Section 4.3(a), if less than all the Outstanding Trust
Securities are to be redeemed on a Redemption Date, then the aggregate
Liquidation Amount of Trust Securities to be redeemed shall be allocated on a
pro rata basis (based on Liquidation Amounts) among the Common Securities and
the Preferred Securities. The particular Preferred Securities to be redeemed
shall be selected on a pro rata basis (based upon Liquidation Amounts) not more
than 60 days prior to the Redemption Date by the Property Trustee from the
Outstanding Preferred Securities not previously called for redemption, by such
method (including, without limitation, by lot) as the Property Trustee shall
deem fair and appropriate and which may provide for the selection for redemption
of portions (equal to $____ or an integral multiple of $____ in excess thereof)
of the Liquidation Amount of Preferred Securities of a denomination larger than
$____. The Property Trustee shall promptly notify the Security Registrar in
writing of the Preferred Securities selected for redemption and, in the case of
any Preferred Securities selected for partial redemption, the Liquidation Amount
thereof to be redeemed. For all purposes of this Trust Agreement, unless the
context otherwise requires, all provisions relating to the redemption of
Preferred Securities shall relate, in the case of any Preferred Securities
redeemed or to be redeemed only in part, to the portion of the Liquidation
Amount of Preferred Securities that has been or is to be redeemed.

SECTION 4.3  SUBORDINATION OF COMMON SECURITIES.


                                       19
<PAGE>

     (a) Payment of Distributions (including Additional Amounts, if applicable)
on, and the Redemption Price of, the Trust Securities, as applicable, shall be
made, subject to Section 4.2(f), pro rata among the Common Securities and the
Preferred Securities based on the Liquidation Amount of the Trust Securities;
provided, however, that if on any Distribution Date or Redemption Date any Event
of Default resulting from a Debenture Event of Default shall have occurred and
be continuing, no payment of any Distribution (including Additional Amounts, if
applicable) on, or Redemption Price of, any Common Security, and no other
payment on account of the redemption, liquidation or other acquisition of Common
Securities, shall be made unless payment in full in cash of all accumulated and
unpaid Distributions (including Additional Amounts, if applicable) on all
Outstanding Preferred Securities for all Distribution periods terminating on or
prior thereto, or in the case of payment of the Redemption Price the full amount
of such Redemption Price on all Outstanding Preferred Securities, shall have
been made or provided for, and all funds immediately available to the Property
Trustee shall first be applied to the payment in full in cash of all
Distributions (including Additional Amounts, if applicable) on, or the
Redemption Price of, Preferred Securities then due and payable.

     (b) In the case of the occurrence of any Event of Default resulting from
any Debenture Event of Default, the Holder of Common Securities will be deemed
to have waived any right to act with respect to any such Event of Default under
this Trust Agreement until the effect of all such Events of Default with respect
to the Preferred Securities have been cured, waived or otherwise eliminated.
Until any such Event of Default under this Trust Agreement with respect to the
Preferred Securities has 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.

SECTION 4.4  PAYMENT PROCEDURES.

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

SECTION 4.5  TAX RETURNS AND REPORTS.

     The Administrative Trustees shall prepare (or cause to be prepared), at the
Depositor's expense, and file all United States Federal, state and local tax and
information returns and reports required to be filed by or in respect of the
Trust. In this regard, the Administrative Trustees shall

     (a) prepare and file (or cause to be prepared and filed) the appropriate
Internal Revenue Service Form required to be filed in respect of the Trust in
each taxable year of the Trust and


                                       20
<PAGE>

     (b) prepare and furnish (or cause to be prepared and furnished) to each
Securityholder the appropriate Internal Revenue Service form required to be
provided on such form. The Administrative Trustees shall provide the Depositor
and the Property Trustee with a copy of all such returns and reports promptly
after such filing or furnishing. The Trustees shall comply with United States
Federal withholding and backup withholding tax laws and information reporting
requirements with respect to any payments to Securityholders under the Trust
Securities.

SECTION 4.6  PAYMENT OF TAXES, DUTIES, ETC.  OF THE TRUST.

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

SECTION 4.7  PAYMENTS UNDER INDENTURE.

     Any amount payable hereunder to any Holder of Preferred Securities shall be
reduced by the amount of any corresponding payment such Holder (and any Owner
with respect thereto) has directly received pursuant to Section 5.8 of the
Indenture.

                                   ARTICLE V.

SECTION 5.1  INITIAL OWNERSHIP.

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

SECTION 5.2  THE TRUST SECURITIES CERTIFICATES.

     The Preferred Securities Certificates shall be issued in minimum
denominations of $____ Liquidation Amount and integral multiples of $____ in
excess thereof, and the Common Securities Certificates shall be issued in

the Trust by manual signature of at least one Administrative Trustee. Trust
Securities Certificates bearing the manual signatures of individuals who were,
at the time when such signatures shall have been affixed, authorized to sign on
behalf of the Trust, shall be validly issued and entitled to the benefits of
this Trust Agreement, notwithstanding that such individuals or any of them shall
have ceased to be so authorized prior to the delivery of such Trust Securities
Certificates or did not hold such offices at the date of delivery of such Trust
Securities Certificates. A transferee of a Trust Securities Certificate shall
become a Securityholder, and shall be entitled to the rights and subject to the
obligations of a Securityholder hereunder, upon due registration of such Trust
Securities Certificate in such transferee's name pursuant to Sections 5.4, 5.11
and 5.13.

SECTION 5.3  EXECUTION AND DELIVERY OF TRUST SECURITIES CERTIFICATES.

     At each Time of Delivery, the Administrative Trustees shall cause Trust
Securities Certificates, in an aggregate Liquidation Amount as provided in
Sections 2.4 and 2.5, to be executed on behalf of the Trust and delivered to or
upon the written order of the Depositor, signed by its Chairman of the Board, a
Vice Chairman, its President, a Vice President or its Treasurer and attested by
its Secretary or one of its Assistant Secretaries, without further corporate
action by the Depositor, in authorized denominations.

SECTION 5.4 REGISTRATION OF TRANSFER AND EXCHANGE OF PREFERRED SECURITIES
CERTIFICATES.

     The Depositor shall keep or cause to be kept, at the office or agency
maintained pursuant to Section 5.8, a register or registers for the purpose of
registering Trust Securities Certificates and transfers and exchanges of
Preferred Securities Certificates (the "Securities Register"). The registrar
designated by the Depositor (the "Securities Registrar"), subject to such
reasonable regulations as it may prescribe, shall provide for the registration
of Preferred Securities Certificates and Common Securities Certificates (subject
to Section 5.10 in the case of the Common Securities Certificates) and
registration of transfers and exchanges of Preferred Securities Certificates as
herein provided. The Bank shall be the initial Securities Registrar. Upon
surrender for registration of transfer of any Preferred Securities Certificate
at the office or agency maintained pursuant to Section 5.8, the Administrative
Trustees or any one of them shall execute and deliver, in the name of the
designated transferee or transferees, one or more new Preferred Securities
Certificates in authorized denominations of a like aggregate Liquidation Amount
dated the date of execution by such Administrative Trustee or Trustees. The
Securities Registrar shall not be required to register the transfer of any
Preferred Securities after such Preferred Securities have been called for
redemption. At the option of a Holder, Preferred Securities Certificates may be
exchanged for other Preferred Securities Certificates in authorized
denominations of the same class and of a like aggregate Liquidation Amount upon
surrender of the Preferred Securities Certificates to be exchanged at the office
or agency maintained pursuant to Section 5.8. Every Preferred Securities
Certificate presented or surrendered for registration of transfer or exchange
shall be accompanied by a written instrument of transfer in form satisfactory to
an Administrative Trustee and the Securities Registrar duly executed by the
Holder or his attorney duly authorized in writing. Each Preferred Securities
Certificate surrendered for registration of transfer or exchange shall be
cancelled and subsequently disposed of by an Administrative Trustee in
accordance with customary practice. Registration of transfers or exchanges of
Preferred Securities Certificates shall be effected without service charge by or
on behalf of the Trust, but the Securities Registrar may require payment of a
sum sufficient to cover any tax or other governmental charge that may be imposed
in connection with any such transfer or exchange.

SECTION 5.5 MUTILATED, DESTROYED, LOST OR STOLEN TRUST SECURITIES CERTIFICATES.

     If (a) any mutilated Trust Securities Certificate shall be surrendered to
the Securities Registrar, or if the Securities Registrar shall receive evidence
to its satisfaction of the destruction,


                                       22
<PAGE>

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

SECTION 5.6  PERSONS DEEMED SECURITYHOLDERS.

     Prior to due presentation of a Trust Securities Certificate for
registration of transfer, the Administrative Trustees or the Securities
Registrar shall treat the Person in whose name any Trust Securities Certificate
shall be registered in the Securities Register as the owner of such Trust
Securities Certificate for the purpose of receiving distributions and for all
other purposes whatsoever, and neither the Trustees nor the Securities Registrar
shall be bound by any notice to the contrary.

SECTION 5.7  ACCESS TO LIST OF SECURITYHOLDERS' NAMES AND ADDRESSES.

     The Administrative Trustees shall furnish or cause to be furnished (x) to
the Depositor, within 15 days after receipt by any Administrative Trustee of a
request therefor from the Depositor in writing and (y) to the Property Trustee,
promptly after receipt by any Administrative Trustee of a request therefor from
the Property Trustee in writing in order to enable the Property Trustee to
discharge its obligations under this Trust Agreement, a list, in such form as
the Depositor or the Property Trustee may reasonably require, of the names and
addresses of the Securityholders as of a recent date. If Holders of Trust
Securities Certificates evidencing ownership at such time and for the previous
six months of not less than 25% of the Outstanding aggregate Liquidation Amount
apply in writing to any Administrative Trustee, and such application states that
the applicants desire to communicate with other Securityholders with respect to
their rights under this Trust Agreement or under the Trust Securities
Certificates and such application is accompanied by a copy of the communication
that such applicants propose to transmit, then the Administrative Trustees
shall, within five Business Days after the receipt of such application, afford
such applicants access during normal business hours to the current list of
Securityholders. Each Holder, by receiving and holding a Trust Securities
Certificate, and each Owner shall be deemed to have agreed not to hold the
Depositor, the Property Trustee or the Administrative Trustees accountable by
reason of the disclosure of its name and address, regardless of the source from
which such information was derived.

SECTION 5.8  MAINTENANCE OF OFFICE OR AGENCY.

     The Administrative Trustees shall maintain in Chicago, Illinois, an office
or offices or agency or agencies where Preferred Securities Certificates may be
surrendered for registration of transfer or exchange and where notices and
demands to or upon the Trustees in respect of the Trust Securities and the Trust
Agreement may be served. The Administrative Trustees initially designate The
First National Bank of Chicago, One First National Plaza, Suite 0126, Chicago,
Illinois 60670-0126; Attention: Corporate Trust Department, as the principal
corporate trust office for such purposes. The Administrative Trustees shall give
prompt written notice to the Depositor and to the Securityholders of any change
in the location of the Securities Register or any such office or agency.

SECTION 5.9  APPOINTMENT OF PAYING AGENT.

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

SECTION 5.10  OWNERSHIP OF COMMON SECURITIES BY DEPOSITOR.

     At each Time of Delivery, the Depositor shall acquire and retain beneficial
and record ownership of all of the Common Securities then issued by the Trust,
in an amount equal to at least 3% of the total capital of the Trust, at the same
time as the Preferred Securities are issued and sold.


                                       24
<PAGE>

The aggregate Liquidation Amount of the Common Securities at any time shall not
be less than 3% of the total capital of the Trust. To the fullest extent
permitted by law, other than a transfer in connection with a consolidation or
merger of the Depositor into another corporation, or any conveyance, transfer or
lease by the Depositor of its properties and assets substantially as an entirety
to any Person, pursuant to Section 8.1 of the Indenture, any attempted transfer
of the Common Securities shall be void. The Administrative Trustees shall cause
each Common Securities Certificate issued to the Depositor to contain a legend
stating "THIS CERTIFICATE IS NOT TRANSFERABLE EXCEPT AS PROVIDED IN THE TRUST
AGREEMENT (AS DEFINED BELOW)".

SECTION 5.11 BOOK-ENTRY PREFERRED SECURITIES CERTIFICATES; COMMON SECURITIES

Such Preferred Securities Certificate or Certificates shall initially be
registered on the Securities Register in the name of Cede & Co., the nominee of
the initial Clearing Agency, and no beneficial owner will receive a Definitive
Preferred Securities Certificate representing such beneficial owner's interest
in such Preferred Securities, except as provided in Section 5.13. Except for

     Preferred Securities and the giving of instructions or directions to Owners
     of Book-Entry Preferred Securities) as the sole Holder of Book-Entry
     Preferred Securities and shall have no obligations to the Owners thereof;

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

          (iv) the rights of the Owners of the Book-Entry Preferred Securities
     Certificates shall be exercised only through the Clearing Agency and shall
     be limited to those established by law and agreements between such Owners
     and the Clearing Agency and/or the Clearing Agency Participants; provided,
     that solely for the purposes of determining whether the Holders of the
     requisite amount of Preferred Securities have voted on any matter provided
     for in this Trust Agreement, so long as Definitive Preferred Security
     Certificates have not been issued, the Trustees may conclusively rely on,
     and shall be protected in relying on, any written instrument (including a
     proxy) delivered to the Trustees by the Clearing Agency setting forth the
     Owners' votes or assigning the right to vote on any matter to any other
     Persons either in whole or in part. Pursuant to the Certificate


                                       25
<PAGE>

     Depository Agreement, unless and until Definitive Preferred Securities
     Certificates are issued pursuant to Section 5.13, the initial Clearing
     Agency will make book-entry transfers among the Clearing Agency
     Participants and receive and transmit payments on the Preferred Securities
     to such Clearing Agency Participants.

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

SECTION 5.12  NOTICES TO CLEARING AGENCY.

     (a) To the extent that a notice or other communication to the Owners is
required under this Trust Agreement, unless and until Definitive Preferred
Securities Certificates shall have been issued to Owners pursuant to Section

herein to be given to Owners to the Clearing Agency, and shall have no
obligations to the Owners.

SECTION 5.13  DEFINITIVE PREFERRED SECURITIES CERTIFICATES.

     If (a) the Depositor advises the Trustees in writing that the Clearing
Agency is no longer willing or able to act as clearing agency with respect to
the Preferred Securities Certificates, and the Depositor fails to appoint a
qualified successor within 90 days, (b) the Depositor at its option advises the
Trustees in writing that it elects to terminate the book-entry system through
the Clearing Agency or (c) after the occurrence of a Debenture Event of Default,
Owners of Preferred Securities Certificates representing beneficial interests
aggregating at least a majority of the Liquidation Amount of the Outstanding
Preferred Securities advise the Property Trustee in writing that the
continuation of a book-entry system through the Clearing Agency is no longer in
the best interest of the Owners of Preferred Securities Certificates, then the
Property Trustee shall notify the Clearing Agency and the Clearing Agency shall
notify all Owners of Preferred Securities Certificates and the other Trustees of
the occurrence of any such event and of the availability of the Definitive
Preferred Securities Certificates to Owners of such class or classes, as
applicable, requesting the same. Upon surrender to the Property Trustee of the
typewritten Preferred Securities Certificate or Certificates representing the
Book Entry Preferred Securities Certificates by the Clearing Agency, accompanied
by registration instructions, the Administrative Trustees, or any one of them,
shall execute the Definitive Preferred Securities Certificates in accordance
with the instructions of the Clearing Agency. Neither the Securities Registrar
nor the Trustees shall be liable for any delay in delivery of such instructions
and may conclusively rely on, and shall be protected in relying on, such
instructions. Upon the issuance of Definitive Preferred Securities Certificates,
the Trustees shall recognize the Holders of the Definitive Preferred Securities
Certificates as Securityholders. The Definitive Preferred Securities
Certificates shall be printed, lithographed or engraved or may be produced in
any other manner as is reasonably acceptable to the Administrative Trustees, as
evidenced by the execution thereof by the Administrative Trustees or any one of
them.

SECTION 5.14  RIGHTS OF SECURITYHOLDERS.

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

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

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

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

               (A) all overdue installments of interest (including any
          Additional Interest) on, and any other Additional Amounts with respect
          to, all of the Debentures,

               (B) the principal of and premium on any Debentures which have
          become due otherwise than by such declaration of acceleration and
          interest thereon and any Additional Amounts with respect thereto at
          the rate or rates borne by or provided for in the Debentures,

               (C) to the extent the payment of such interest or Additional
          Amounts is lawful, interest upon overdue installments of any interest
          and Additional Amounts at the rate or rates borne by or provided for
          in the Debentures, and


                                       27
<PAGE>

               (D) all sums paid or advanced by the Debenture Trustee under the
          Indenture and the reasonable compensation, expenses, disbursements and
          advances of the Debenture Trustee, its agents and counsel and all
          other amounts due the Debenture Trustee under the Indenture; and

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

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

     The Holders of not less than a majority in Liquidation Amount of the
Preferred Securities then Outstanding may, on behalf of the Holders of all the
Preferred Securities, waive any past default under the Indenture, except a
default (i) in the payment of principal of, any premium or interest (including
any Additional Interest) on, or any other Additional Amounts with respect to,
the Debentures or (ii) in respect of a covenant or provision which under the
Indenture cannot be modified or amended without the consent of the holder of
each outstanding Debenture.

     Upon receipt by the Property Trustee of written notice declaring such an
acceleration, or rescission and annulment thereof, by Holders of the Preferred
Securities all or part of which are represented by Book-Entry Preferred
Securities Certificates, a record date shall be established for determining
Holders of Outstanding Preferred Securities entitled to join in such notice,
which record date shall be at the close of business on the day the Property
Trustee receives such notice. The Holders on such record date, or their duly
designated proxies, and only such Persons, shall be entitled to join in such
notice, whether or not such Holders remain Holders after such record date;
provided, that, unless such declaration of acceleration, or rescission and
annulment, as the case may be, shall have become effective by virtue of the
requisite percentage having joined in such notice prior to the day which is 90
days after such record date, such notice of declaration of acceleration, or
rescission and annulment, as the case may be, shall automatically and without
further action by any Holder be canceled and of no further effect. Nothing in
this paragraph shall prevent a Holder, or a proxy of a Holder, from giving,
after expiration of such 90-day period, a new written notice of declaration of
acceleration, or rescission and annulment thereof, as the case may be, that is
identical to a written notice which has been canceled pursuant to the proviso to
the preceding sentence, in which event a new record date shall be established
pursuant to the provisions of this Section 5.14(b).

     (c) For so long as any Preferred Securities remain Outstanding, to the
fullest extent permitted by law and subject to the terms of this Trust Agreement
and the Indenture, any Holder of Preferred Securities shall have the right, upon
a Debenture Event of Default specified in Section 5.1(1) or 5.1(2) of the
Indenture, to institute directly a proceeding against the Debenture Issuer or
the Debenture Guarantor, as the case may be, pursuant to Section 5.8 of the
Indenture, for enforcement of payment to such Holder of the principal of, and
any premium and (subject to the provisions of the Indenture) interest (including
any Additional Interest) on, and any other


                                       28
<PAGE>

Additional Amounts with respect to, such Debentures having a principal amount
equal to the Liquidation Amount of the Preferred Securities of such Holder (a
"Direct Action"). In connection with any such Direct Action, the rights of the
Holders of Common Securities will be subrogated to the rights of any Holder of
Preferred Securities to the extent of any payment made by the Debenture Issuer
or the Debenture Guarantor, as the case may be, to such Holder of Preferred
Securities as a result of such Direct Action. Except as set forth in Section
5.14(b) and (c), or as otherwise contemplated by the Indenture, the Holders of
Preferred Securities shall have no right to exercise directly any right or
remedy available to the holders of, or in respect of, the Debentures.

                                  ARTICLE VI.

                   ACTS OF SECURITYHOLDERS; MEETINGS; VOTING

SECTION 6.1  LIMITATIONS ON VOTING RIGHTS.

     (a) Except as provided in this Section, in Sections 5.14, 8.10 and 10.2 and
in the Indenture and as otherwise required by law, no Holder of Preferred
Securities shall have any right to vote or in any manner otherwise control the
administration, operation and management of the Trust or the obligations of the
parties hereto, nor shall anything herein set forth, or contained in the terms
of the Trust Securities Certificates, be construed so as to constitute the
Securityholders from time to time as partners or members of an association.

     (b) So long as any Debentures are held by the Property Trustee, the
Trustees shall not

          (i) direct the time, method and place of conducting any proceeding for
     any remedy available to the Debenture Trustee, or executing any trust or
     power conferred on the Debenture Trustee with respect to such Debentures,

          (ii) waive any past default which is waivable under Section 5.13 of
     the Indenture,

          (iii) exercise any right to rescind or annul a declaration that the
     principal of all the Debentures shall be due and payable, or

          (iv) consent to any amendment, modification or termination of the
     Indenture or the Debentures, where such consent shall be required,

without, in each case, obtaining the prior approval of the Holders of at least a
majority in Liquidation Amount of all Outstanding Preferred Securities;
provided, however, that where a consent under the Indenture would require the
consent of each holder of Debentures affected thereby, no such consent shall be
given by the Property Trustee without the prior written consent of each Holder
of Preferred Securities. The Trustees shall not revoke any action previously
authorized or approved by a vote of the Holders of Preferred Securities, except
by a subsequent vote of the Holders of Preferred Securities. The Property
Trustee shall notify all Holders of the Preferred Securities of any notice of
default received from the Debenture Trustee with respect to


                                       29
<PAGE>

the Debentures. In addition to obtaining the foregoing approvals of the Holders
of the Preferred Securities, prior to taking any of the foregoing actions, the
Trustees shall, at the expense of the Depositor, obtain an Opinion of Counsel
rendered by counsel experienced in such matters to the effect that the Trust
will not be classified as an association taxable as a corporation for United
States Federal income tax purposes on account of such action.

     (c) If any proposed amendment to the Trust Agreement provides for, or the
Trustees otherwise propose to effect,

          (i) any action that would adversely affect in any material respect the
     powers, preferences or special rights of the Preferred Securities, whether
     by way of amendment to the Trust Agreement or otherwise, or

          (ii) the dissolution, winding-up or termination of the Trust, other
     than pursuant to the terms of this Trust Agreement, then the Holders of
     Outstanding Preferred Securities as a class will be entitled to vote on
     such amendment or proposal and such amendment or proposal shall not be
     effective except with the approval of the Holders of at least a majority in
     Liquidation Amount of the Outstanding Preferred Securities. No amendment to
     this Trust Agreement may be made if, as a result of such amendment, the
     Trust would be classified as an association taxable as a corporation for
     United States federal income tax purposes.

SECTION 6.2  NOTICE OF MEETINGS.

     Notice of all meetings of the Preferred Securityholders, stating the time,
place and purpose of the meeting, shall be given by the Property Trustee
pursuant to Section 10.8 to each Preferred Securityholder of record, at his
registered address, at least 15 days and not more than 90 days before the
meeting. At any such meeting, any business properly before the meeting may be so
considered whether or not stated in the notice of the meeting. Any adjourned
meeting may be held as adjourned without further notice.

SECTION 6.3  MEETINGS OF PREFERRED SECURITYHOLDERS.

     No annual meeting of Securityholders is required to be held. The
Administrative Trustees, however, shall call a meeting of Securityholders to
vote on any matter upon the written request of the Preferred Securityholders of
record of 25% of the Preferred Securities (based upon their Liquidation Amount)
and the Administrative Trustees or the Property Trustee may, at any time in
their discretion, call a meeting of Preferred Securityholders to vote on any
matters as to which Preferred Securityholders are entitled to vote. Preferred
Securityholders of record of 50% of the Outstanding Preferred Securities (based
upon their Liquidation Amount), present in person or by proxy, shall constitute
a quorum at any meeting of Securityholders. If a quorum is present at a meeting,
an affirmative vote by the Preferred Securityholders of record present, in
person or by proxy, holding a majority of the Preferred Securities (based upon
their Liquidation Amount) held by the Preferred Securityholders of record
present, either in person or by proxy, at such meeting


                                       30
<PAGE>

shall constitute the action of the Securityholders, unless this Trust Agreement
requires a greater number of affirmative votes.

SECTION 6.4  VOTING RIGHTS.

     Securityholders shall be entitled to one vote for each $____ of Liquidation
Amount represented by their Trust Securities in respect of any matter as to
which such Securityholders are entitled to vote.

SECTION 6.5  PROXIES, ETC.

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

SECTION 6.6  SECURITYHOLDER ACTION BY WRITTEN CONSENT.

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

SECTION 6.7  RECORD DATE FOR VOTING AND OTHER PURPOSES.

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


                                       31

SECTION 6.8  ACTS OF SECURITYHOLDERS.

     Any request, demand, authorization, direction, notice, consent, waiver or
other action provided or permitted by this Trust Agreement to be given, made or
taken by Securityholders or Owners may be embodied in and evidenced by one or
more instruments of substantially similar tenor signed by such Securityholders
or Owners in person or by an agent duly appointed in writing; and, except as
otherwise expressly provided herein, such action shall become effective when
such instrument or instruments are delivered to an Administrative Trustee. Such
instrument or instruments (and the action embodied therein and evidenced
thereby) are herein sometimes referred to as the "Act" of the Securityholders or
Owners signing such instrument or instruments. Proof of execution of any such
instrument or of a writing appointing any such agent shall be sufficient for any
purpose of this Trust Agreement and (subject to Section 8.1) conclusive in favor
of the Trustees, if made in the manner provided in this Section. The fact and
date of the execution by any Person of any such instrument or writing may be
proved by the affidavit of a witness of such execution or by a certificate of a
notary public or other officer authorized by law to take acknowledgments of
deeds, certifying that the individual signing such instrument or writing
acknowledged to him the execution thereof. Where such execution is by a signer
acting in a capacity other than his individual capacity, such certificate or
affidavit shall also constitute sufficient proof of his authority. The fact and
date of the execution of any such instrument or writing, or the authority of the
Person executing the same, may also be proved in any other manner which any
Trustee receiving the same deems sufficient. The ownership of Preferred
Securities shall be proved by the Securities Register. Any request, demand,
authorization, direction, notice, consent, waiver or other Act of the
Securityholder of any Trust Security shall bind every future Securityholder of
the same Trust Security and the Securityholder of every Trust Security issued
upon the registration of transfer thereof or in exchange therefor or in lieu
thereof in respect of anything done, omitted or suffered to be done by the
Trustees or the Trust in reliance thereon, whether or not notation of such
action is made upon such Trust Security. Without limiting the foregoing, a
Securityholder entitled hereunder to take any action hereunder with regard to
any particular Trust Security may do so with regard to all or any part of the
Liquidation Amount of such Trust Security or by one or more duly appointed
agents each of which may do so pursuant to such appointment with regard to all
or any part of such Liquidation Amount. If any dispute shall arise between the
Securityholders and the Administrative Trustees or among such Securityholders or
Trustees with respect to the authenticity, validity or binding nature of any
request, demand, authorization, direction, consent, waiver or other Act of such
Securityholder or Trustee under this Article VI, then the determination of such
matter by the Property Trustee shall be conclusive with respect to such matter.

SECTION 6.9  INSPECTION OF RECORDS.

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

giving of notice to, the registration with or the taking of any other action

     (f) there are no proceedings pending or, to the best of each of the
Property Trustee's and the Delaware Trustee's knowledge, threatened against or
affecting the Property Trustee or the Delaware Trustee in any court or before
any governmental authority, agency or arbitration board or tribunal which,
individually or in the aggregate, would materially and adversely affect the
Trust or would question the right, power and authority of the Property Trustee
or the Delaware Trustee, as the case may be, to enter into or perform its
obligations as one of the Trustees under this Trust Agreement.

SECTION 7.2  REPRESENTATIONS AND WARRANTIES OF DEPOSITOR

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

     (a) the Trust Securities Certificates issued at each Time of Delivery on
behalf of the Trust have been duly authorized and will have been, duly and
validly executed, issued and delivered by the Trustees pursuant to the terms and

and the Securityholders will be, as of each such date, entitled to the benefits
of this Trust Agreement; and

     (b) there are no taxes, fees or other governmental charges payable by the

case may be, of this Trust Agreement.

                                  ARTICLE VIII.

                                  THE TRUSTEES

SECTION 8.1  CERTAIN DUTIES AND RESPONSIBILITIES.

     (a) The duties and responsibilities of the Trustees shall be as provided by
this Trust Agreement and, in the case of the Property Trustee, subject to the
Trust Indenture Act. Notwithstanding the foregoing, no provision of this Trust
Agreement shall require the Trustees to expend or risk their own funds or
otherwise incur any financial liability in the performance of any of their
duties hereunder, or in the exercise of any of their rights or powers, if they
shall have reasonable grounds for believing that repayment of such funds or
adequate indemnity against such risk or liability is not reasonably assured to
it. Whether or not therein expressly so provided, every provision of this Trust
Agreement relating to the conduct or affecting the liability of or affording
protection to the Trustees shall be subject to the provisions of this Section.
To the extent that, at law or in equity, an Administrative Trustee has duties
(including fiduciary duties) and liabilities


                                       34
<PAGE>

relating thereto to the Trust or to the Securityholders, such Administrative
Trustee shall not be liable to the Trust or to any Securityholder for such
Trustee's good faith reliance on the provisions of this Trust Agreement. The
provisions of this Trust Agreement, to the extent that they restrict the duties
and liabilities of the Administrative Trustees otherwise existing at law or in
equity, are agreed by the Depositor and the Securityholders to replace such
other duties and liabilities of the Administrative Trustees.

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

     (c) No provision of this Trust Agreement shall be construed to relieve the
Property Trustee from liability for its own bad faith, negligence or willful
misconduct, except that: (i) the Property Trustee undertakes to perform only
those duties specifically set forth in this Agreement, provided that, it must
exercise the same degree of care as a prudent person would exercise in the
conduct of his or her own affairs; (ii) the Property Trustee shall not be liable
for any error of judgment made in good faith by an authorized officer of the
Property Trustee, unless it shall be proved that the Property Trustee was
negligent in ascertaining the pertinent facts; (iii) 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; (iv) the Property Trustee's sole duty with
respect to the custody, safe keeping and physical preservation of the Debentures
and the Payment Account shall be to deal with such Property in a similar manner
as the Property Trustee deals with similar property for its own account, subject
to the protections and limitations on liability afforded to the Property Trustee
under this Trust Agreement and the Trust Indenture Act; (v) the Property Trustee
shall not be liable for any interest on any money received by it except as it
may otherwise agree with the Depositor; and money held by the Property Trustee
need not be segregated from other funds held by it except in relation to the
Payment Account maintained by the Property Trustee pursuant to Section 3.1 and
except to the extent otherwise required by law; and (vi) the Property Trustee
shall not be responsible for monitoring the compliance by the Administrative
Trustees or the Depositor with their respective duties under this Trust
Agreement, nor shall the Property Trustee be liable for the default or
misconduct of the Administrative Trustees or the Depositor.

<PAGE>

SECTION 8.2  CERTAIN NOTICES.

     Within five (5) Business Days after the occurrence of any Event of Default
actually known to the Property Trustee, the Property Trustee shall transmit, in
the manner and to the extent provided in Section 10.8, notice of such Event of
Default to the Securityholders, the Administrative Trustees and the Depositor,
unless such Event of Default shall have been cured or waived. Within five
Business Days after the receipt of notice of the Debenture Issuer's exercise of
its right to defer the payment of interest on the Debentures pursuant to the
Indenture, the Administrative Trustees shall transmit, in the manner and to the
extent provided in Section 10.8, notice of such exercise to the Securityholders
and the Property Trustee, unless such exercise shall have been revoked.

SECTION 8.3  CERTAIN RIGHTS OF PROPERTY TRUSTEE.

     Subject to the provisions of Section 8.1:

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

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

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

     (d) whenever in the administration of this Trust Agreement, the Property
Trustee shall deem it desirable that a matter be established before undertaking,
suffering or omitting any action


                                       36
<PAGE>

hereunder, the Property Trustee (unless other evidence is herein specifically
prescribed) may, in the absence of bad faith on its part, request and rely upon
an Officers' Certificate which, upon receipt of such request, shall be promptly
delivered by the Depositor or the Administrative Trustees;

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

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

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

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

     (i) the Property Trustee may execute any of the trusts or powers hereunder
or perform any duties hereunder either directly or by or through its agents or
attorneys, provided that the Property Trustee shall be responsible for its own
negligence or recklessness with respect to selection of any agent or attorney
appointed by it hereunder;

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

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


                                       37
<PAGE>

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

SECTION 8.4  NOT RESPONSIBLE FOR RECITALS OR ISSUANCE OF SECURITIES.

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

SECTION 8.5  MAY HOLD SECURITIES.

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

SECTION 8.6  COMPENSATION; INDEMNITY; FEES.

     The Depositor agrees:

     (a) to pay to the Trustees from time to time reasonable compensation for
all services rendered by them hereunder (which compensation shall not be limited
by any provision of law in regard to the compensation of a trustee of an express
trust);

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

     (c) to indemnify each of the Trustees or any predecessor Trustee for, and
to hold the Trustees harmless against, any loss, damage, claims, liability,
penalty or expense incurred without bad faith, negligence or willful misconduct
on its part, arising out of or in connection with the acceptance or
administration of this Trust Agreement, including the costs and expenses of
defending itself against any claim or liability in connection with the exercise
or performance of any of its powers or duties hereunder.

     The provisions of this Section 8.6 shall survive the termination of this
Trust Agreement or the resignation or removal of any Trustee. No Trustee may
claim any lien or charge on any Trust Property as a result of any amount due
pursuant to this Section 8.6.

SECTION 8.7  CORPORATE PROPERTY TRUSTEE REQUIRED; ELIGIBILITY OF TRUSTEES.

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

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

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

SECTION 8.8  CONFLICTING INTERESTS.

     If the Property Trustee has or shall acquire a conflicting interest within
the meaning of the Trust Indenture Act, the Property Trustee shall either
eliminate such interest or resign, to the extent and in the manner provided by,
and subject to the provisions of, the Trust Indenture Act and this Trust
Agreement. Subject to the foregoing, the Depositor and any Trustee 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 shall have no rights by virtue of this
Trust Agreement in and to such independent ventures or the income or profits
derived therefrom, and the pursuit of any such venture, even if competitive with
the business of the Trust, shall not be deemed wrongful or improper. Neither the
Depositor, nor any Trustee, shall be obligated to present any particular
investment or other opportunity to the Trust even if such opportunity is of a
character that, if presented to the Trust, could be taken by the Trust, and the
Depositor or any Trustee shall have the right to take for its own account
(individually or as a partner or fiduciary) or to recommend to others any such
particular investment or other opportunity. Any Trustee may engage in any
financial or other transaction with the Depositor or any Affiliate of the
Depositor, or may act as depository for, trustee or agent for, or act on any
committee or body of holders of, securities or other obligations of the
Depositor or its Affiliates.

SECTION 8.9  CO-TRUSTEES AND SEPARATE TRUSTEE.

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

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

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

     (c) The Property Trustee at any time, by an instrument in writing executed
by it, with the written concurrence of the Depositor, may accept the resignation
of or remove any co-trustee or separate trustee appointed under this Section,
and, in case a Debenture Event of Default has occurred and is continuing, the
Property Trustee shall have power to accept the resignation of, or


                                       40
<PAGE>

remove, any such co-trustee or separate trustee without the concurrence of the
Depositor. Upon the written request of the Property Trustee, the Depositor shall
join with the Property Trustee in the execution, delivery and performance of all
instruments and agreements necessary or proper to effectuate such resignation or
removal. A successor to any co-trustee or separate trustee so resigned or
removed may be appointed in the manner provided in this Section.

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

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

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

SECTION 8.10  RESIGNATION AND REMOVAL; APPOINTMENT OF SUCCESSOR.

     No resignation or removal of any Trustee (the "Relevant Trustee") and no
appointment of a successor Trustee pursuant to this Article shall become
effective until the acceptance of appointment by the successor Trustee in
accordance with the applicable requirements of Section 8.11. Subject to the
immediately preceding sentence, the Relevant Trustee may resign at any time with
respect to the Trust Securities by giving written notice thereof to the
Depositor. If the instrument of acceptance by the successor Trustee required by
Section 8.11 shall not have been delivered to the Relevant Trustee within 30
days after the giving of such notice of resignation, the Relevant Trustee may
petition, at the expense of the Depositor, any court of competent jurisdiction
for the appointment of a successor Relevant Trustee with respect to the Trust
Securities. Unless a Debenture Event of Default shall have occurred and be
continuing, any Trustee may be removed at any time by Act of the Common
Securityholder. If a Debenture Event of Default shall have occurred and be
continuing, the Property Trustee or the Delaware Trustee, or both of them, may
be removed at such time by Act of the Holders of a majority in Liquidation
Amount of the Preferred Securities, delivered to the Relevant Trustee (in its
individual capacity and on behalf of the Trust). In no event will the Holders of
Preferred Securities have the right to vote to appoint, remove or replace the
Administrative Trustees. An Administrative Trustee may be removed by Act of the
Common Securityholder at any time. If any Trustee shall resign, be removed or
become incapable of acting as Trustee, or if a vacancy shall occur in the office
of any Trustee for any cause, at a time when no Debenture Event of Default shall
have occurred and be continuing, the Common Securityholder, by Act of the Common
Securityholder delivered to the retiring Trustee, shall promptly appoint a


                                       41
<PAGE>

successor Trustee or Trustees with respect to the Trust Securities and the
Trust, and the retiring Trustee shall comply with the applicable requirements of
Section 8.11. If the Property Trustee or the Delaware Trustee shall resign, be
removed or become incapable of continuing to act as the Property Trustee or the
Delaware Trustee, as the case may be, at a time when a Debenture Event of
Default shall have occurred and be continuing, the Preferred Securityholders, by
Act of the Securityholders of a majority in Liquidation Amount of the Preferred
Securities then Outstanding delivered to the retiring Relevant Trustee, shall
promptly appoint a successor Relevant Trustee or Trustees with respect to the
Trust Securities and the Trust, and such successor Trustee shall comply with the
applicable requirements of Section 8.11. If an Administrative Trustee shall
resign, be removed or become incapable of acting as Administrative Trustee, at a
time when a Debenture Event of Default shall have occurred and be continuing,
the Common Securityholder by Act of the Common Securityholder delivered to the
Administrative Trustee shall promptly appoint a successor Administrative Trustee
or Administrative Trustees with respect to the Trust Securities and the Trust,
and such successor Administrative Trustee or Trustees shall comply with the
applicable requirements of Section 8.11. If no successor Relevant Trustee with
respect to the Trust Securities shall have been so appointed by the Common
Securityholder or the Preferred Securityholders and accepted appointment in the
manner required by Section 8.11, any Securityholder who has been a
Securityholder of Trust Securities for at least six months may, on behalf of
himself and all others similarly situated, petition any court of competent
jurisdiction for the appointment of a successor Relevant Trustee with respect to
the Trust Securities. The Depositor shall give notice of each resignation and
each removal of the Property Trustee or the Delaware Trustee and each
appointment of a successor Property Trustee or Delaware Trustee to all
Securityholders in the manner provided in Section 10.8. Each notice shall
include the name of the successor Relevant Trustee and the address of its
Corporate Trust Office if it is the Property Trustee. Notwithstanding the
foregoing or any other provision of this Trust Agreement, in the event any
Administrative Trustee or a Delaware Trustee who is a natural person dies or
becomes, in the opinion of the Depositor, incompetent or incapacitated, the
vacancy created by such death, incompetence or incapacity may be filled by (a)
the unanimous act of remaining Administrative Trustees if there are at least two
of them or (b) otherwise by the Depositor (with the successor in each case being
a Person who satisfies the eligibility requirement for Administrative Trustees
set forth in Section 8.7).

SECTION 8.11  ACCEPTANCE OF APPOINTMENT BY SUCCESSOR.

     In case of the appointment hereunder of a successor Trustee such successor
Trustee so appointed shall execute, acknowledge and deliver to the Trust and to
the retiring Trustee an instrument accepting such appointment, and thereupon the
resignation or removal of the retiring Trustee shall become effective and such
successor Trustee, without any further act, deed or conveyance, shall become
vested with all the rights, powers, trusts and duties of the retiring Trustee;
but, on the request of the Depositor or the successor Trustee, such retiring
Trustee shall, upon payment of its charges, execute and deliver an instrument
transferring to such successor Trustee all the rights, powers and trusts of the
retiring Trustee and if the Property Trustee is the resigning Trustee shall duly
assign, transfer and deliver to the successor Trustee all property and money
held by such retiring Property Trustee hereunder. In case of the appointment
hereunder of a successor Relevant Trustee with respect to the Trust Securities
and the Trust, the retiring Relevant Trustee and each successor Relevant Trustee
with respect to the Trust Securities shall execute and deliver an amendment
hereto wherein each successor Relevant Trustee shall accept such appointment and
which


                                       42
<PAGE>

     (a) shall contain such provisions as shall be necessary or desirable to
transfer and confirm to, and to vest in, each successor Relevant Trustee all the
rights, powers, trusts and duties of the retiring Relevant Trustee with respect
to the Trust Securities and the Trust and

     (b) shall add to or change any of the provisions of this Trust Agreement as
shall be necessary to provide for or facilitate the administration of the trusts
hereunder by more than one Relevant Trustee, it being understood that nothing
herein or in such amendment shall constitute such Relevant Trustees co-trustees
of the same trust and that each such Relevant Trustee shall be trustee of a
trust or trusts hereunder separate and apart from any trust or trusts hereunder
administered by any other such Relevant Trustee and upon the execution and
delivery of such amendment the resignation or removal of the retiring Relevant
Trustee shall become effective to the extent provided therein and each such
successor Relevant Trustee, without any further act, deed or conveyance, shall
become vested with all the rights, powers, trusts and duties of the retiring
Relevant Trustee with respect to the Trust Securities and the Trust; but, on
request of the Trust or any successor Relevant Trustee such retiring Relevant
Trustee shall duly assign, transfer and deliver to such successor Relevant
Trustee all Trust Property, all proceeds thereof and money held by such retiring
Relevant Trustee hereunder with respect to the Trust Securities and the Trust.
Upon request of any such successor Relevant Trustee, the Trust shall execute any
and all instruments for more fully and certainly vesting in and confirming to
such successor Relevant Trustee all such rights, powers and trusts referred to
in the first or second preceding paragraph, as the case may be. No successor
Relevant Trustee shall accept its appointment unless at the time of such
acceptance such successor Relevant Trustee shall be qualified and eligible under
this Article.

SECTION 8.12 MERGER, CONVERSION, CONSOLIDATION OR SUCCESSION TO BUSINESS.

     Any corporation into which the Property Trustee or the Delaware Trustee (or
any Administrative Trustee that is not a natural person) may be merged or
converted or with which it may be consolidated, or any corporation resulting
from any merger, conversion or consolidation to which such Relevant Trustee
shall be a party, shall be the successor of such Relevant Trustee hereunder,
provided such corporation shall be otherwise qualified and eligible under this
Article, without the execution or filing of any paper or any further act on the
part of any of the parties hereto.

SECTION 8.13 PREFERENTIAL COLLECTION OF CLAIMS AGAINST DEPOSITOR, DEBENTURE
ISSUER OR TRUST.

     If and when the Property Trustee or the Delaware Trustee shall be or become
a creditor of the Depositor, the Debenture Issuer or the Trust (or any other
obligor upon the Debentures or the Trust Securities), the Property Trustee or
the Delaware Trustee, as the case may be, shall be subject to and shall take all
actions necessary in order to comply with the provisions of the Trust Indenture
Act regarding the collection of claims against the Depositor, Debenture Issuer
or Trust (or any such other obligor).


                                       43

SECTION 8.14 REPORTS BY PROPERTY TRUSTEE.

     (a) Within 60 days after September 15 of each year commencing with the
first September 15 following the first issuance of Preferred Securities pursuant
to this Trust Agreement, the Property Trustee shall transmit to all
Securityholders in accordance with Section 10.8, and to the Depositor, a brief
report dated as of such September 15 with respect to: (i) its eligibility under
Section 8.7 or, in lieu thereof, if to the best of its knowledge it has
continued to be eligible under said Section, a written statement to such effect;
(ii) a statement that the Property Trustee has complied with all of its
obligations under this Trust Agreement during the twelve-month period (or, in
the case of the initial report, the period since the Closing Time) ending with
such September 15 or, if the Property Trustee has not complied in any material
respect with such obligations, a description of such noncompliance; and (iii)
any change in the property and funds in its possession as Property Trustee since
the date of its last report and any action taken by the Property Trustee in the
performance of its duties hereunder which it has not previously reported and
which in its opinion materially affects the Trust Securities.

     (b) In addition the Property Trustee shall transmit to Securityholders such
reports concerning the Property Trustee and its actions under this Trust
Agreement as may be required pursuant to the Trust Indenture Act at the times
and in the manner provided pursuant thereto.

     (c) A copy of each such report shall, at the time of such transmission to
Holders, be filed by the Property Trustee with each stock exchange, interdealer
quotation system or other self-regulatory organization upon which the Trust
Securities are listed or traded, with the Commission and with the Depositor.

SECTION 8.15 REPORTS TO THE PROPERTY TRUSTEE.

     The Depositor and the Administrative Trustees on behalf of the Trust shall
provide to the Property Trustee such documents, reports and information as
required by Section 314 of the Trust Indenture Act (if any) and the compliance
certificate required by Section 314(a) of the Trust Indenture Act in the form,
in the manner and at the times required by Section 314 of the Trust Indenture
Act.

SECTION 8.16 EVIDENCE OF COMPLIANCE WITH CONDITIONS PRECEDENT.

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

SECTION 8.17 NUMBER OF TRUSTEES.

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



                                       44
<PAGE>

The Property Trustee and the Delaware Trustee may be the same person if the
Property Trustee meets the applicable requirements.

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

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

SECTION 8.18 DELEGATION OF POWER.

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

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

                                   ARTICLE IX.

                DISSOLUTION, LIQUIDATION, TERMINATION AND MERGER

SECTION 9.1 DISSOLUTION UPON EXPIRATION DATE.

     Unless earlier dissolved, the Trust shall automatically dissolve on
December 31, 2054 (the "Expiration Date").

SECTION 9.2  EARLY DISSOLUTION.

     The first to occur of any of the following events is an "Early Termination
Event", upon the occurrence of which the Trust shall be dissolved:

     (a) the occurrence of a Bankruptcy Event in respect of, or the dissolution
or liquidation of, the Debenture Issuer or the Debenture Guarantor;


                                       45
<PAGE>

     (b) the written direction to the Property Trustee from the Depositor at any
time (which direction is optional and wholly within the discretion of the
Depositor) to dissolve the Trust and distribute a Like Amount of Debentures to
Securityholders in exchange for the Trust Securities;

     (c) the redemption of all of the Trust Securities in connection with the
redemption of all the Debentures; and

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

SECTION 9.3  TERMINATION.

     The respective obligations and responsibilities of the Trustees and the
Trust shall terminate upon the latest to occur of the following:

         (a) the distribution by the Property Trustee to Securityholders upon
the liquidation of the Trust pursuant to Section 9.4, or upon the redemption of
all of the Trust Securities pursuant to Section 4.2, of all amounts required to
be distributed hereunder upon the final payment of the Trust Securities;

     (b) the payment of any expenses owed by the Trust; and

     (c) the discharge of all administrative duties of the Administrative
Trustees, including the performance of any tax reporting obligations with
respect to the Trust or the Securityholders.

SECTION 9.4 LIQUIDATION.

     (a) If an Early Termination Event specified in clause (a), (b), or (d) of
Section 9.2 occurs or upon the Expiration Date, the Trust shall be liquidated by
the Trustees as expeditiously as the Trustees determine to be possible by
distributing, after satisfaction of liabilities to creditors of the Trust as
provided by applicable law, to each Securityholder a Like Amount of Debentures,
subject to Section 9.4(e).

     (b) Notice of liquidation shall be given by the Property Trustee by
first-class mail, postage prepaid mailed not later than 30 nor more than 60 days
prior to the Liquidation Date to each Holder of Trust Securities at such
Holder's address appearing in the Securities Register. All notices of
liquidation shall: (i) state the Liquidation Date; (ii) state that from and
after the Liquidation Date, the Trust Securities will no longer be deemed to be
Outstanding and any Trust Securities Certificates not surrendered for exchange
will be deemed to represent a Like Amount of Debentures; and (iii) provide such
information with respect to the mechanics by which Holders may exchange Trust
Securities Certificates for Debentures, or if Section 9.4(e) applies, receive a
Liquidation Distribution, as the Administrative Trustees or the Property Trustee
shall deem appropriate.

     (c) Except where Section 9.2(c) or 9.4(e) applies, in order to effect the
liquidation of the Trust and distribution of the Debentures to Securityholders,
the Property Trustee shall establish a



                                       46
<PAGE>

record date for such distribution (which shall be not more than 45 days prior to
the Liquidation Date) and, either itself acting as exchange agent or through the
appointment of a separate exchange agent, shall establish such procedures as it
shall deem appropriate to effect the distribution of Debentures in exchange for
the Outstanding Trust Securities Certificates.

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

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

SECTION 9.5 MERGERS, CONSOLIDATIONS, AMALGAMATIONS OR REPLACEMENTS OF THE TRUST.

     The Trust may not merge with or into, convert into, consolidate,
amalgamate, or be replaced by, or convey, transfer or lease its properties and
assets substantially as an entirety to any corporation or other entity, except
pursuant to this Section 9.5 or Section 9.4. The Trust may, at the


                                       47
<PAGE>

request of the Depositor, with the consent of only the Administrative Trustees
and without the consent of the Holders of the Preferred Securities, merge with
or into, convert into, consolidate, amalgamate, or be replaced by or convey,
transfer or lease its properties and assets substantially as an entirety to a
trust organized as such under the laws of any State; provided, that (i) such
successor entity either (a) expressly assumes all of the obligations of the
Trust with respect to the Preferred Securities or (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 rank in priority with
respect to distributions and payments upon liquidation, redemption and
otherwise, (ii) the Depositor expressly appoints a trustee of such successor
entity possessing the same powers and duties as the Property Trustee as the
holder of the Debentures, (iii) the Successor Securities are listed or traded,
or any Successor Securities will be listed upon notification of issuance, on any
national securities exchange or other organization on which the Preferred
Securities are then listed or traded, if any, (iv) such merger, conversion,
consolidation, amalgamation, replacement, conveyance, transfer or lease does not
cause the Preferred Securities (including any Successor Securities) to be
downgraded by any nationally recognized statistical rating organization, (v)
such merger, conversion, consolidation, amalgamation, replacement, conveyance,
transfer or lease does not adversely affect the rights, preferences and
privileges of the Holders of the Preferred Securities (including any Successor
Securities) in any material respect, (vi) such successor entity has a purpose
substantially identical to that of the Trust, (vii) prior to such merger,
conversion, consolidation, amalgamation, replacement, conveyance, transfer or
lease, the Depositor has received an Opinion of Counsel rendered by independent
counsel experienced in such matters to the effect that (a) such merger,
conversion, consolidation, amalgamation, replacement, conveyance, transfer or
lease does not adversely affect the rights, preferences and privileges of the
Holders of the Preferred Securities (including any Successor Securities) in any
material respect, and (b) following such merger, conversion, consolidation,
amalgamation, replacement, conveyance, transfer or lease, neither the Trust nor
such successor entity will be required to register as an investment company
under the Investment Company Act and (viii) the Depositor (or any permitted
successor or assignee) owns all of the common securities of such successor
entity and guarantees the obligations of such successor entity under the
Successor Securities at least to the extent provided by the Guarantee.

                            MISCELLANEOUS PROVISIONS

SECTION 10.1 LIMITATION OF RIGHTS OF SECURITYHOLDERS.

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

SECTION 10.2 AMENDMENT.

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

     (b) Except as provided in Section 10.2(c) hereof, any provision of this
Trust Agreement may be amended by the Trustees and the Depositor with (i) the
consent of Trust Securityholders representing not less than a majority (based
upon Liquidation Amounts) of the Trust Securities then Outstanding and (ii)
receipt by the Trustees of an Opinion of Counsel to the effect that such
amendment or the exercise of any power granted to the Trustees in accordance
with such amendment will not affect the Trust's status as a grantor trust for
United States Federal income tax purposes or the Trust's exemption from status
of an investment company under the Investment Company Act.

     (c) In addition to and notwithstanding any other provision in this Trust
Agreement, without the consent of each affected Securityholder, this Trust
Agreement may not be amended to (i) change the amount or timing of any
Distribution on the Trust Securities or otherwise adversely affect the amount of
any Distribution required to be made in respect of the Trust Securities as of a
specified date or (ii) restrict the right of a Securityholder to institute suit
for the enforcement of any such payment on or after such date. Notwithstanding
any other provision herein, without the unanimous consent of the
Securityholders, this paragraph (c) of this Section 10.2 may not be amended.

     (d) Notwithstanding any other provisions of this Trust Agreement, no
Trustee shall enter into or consent to any amendment to this Trust Agreement

status of an investment company under the Investment Company Act or fail or
cease to be classified as a grantor trust for United States Federal income tax
purposes.

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

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

or impaired thereby.

SECTION 10.5  PAYMENTS DUE ON NON-BUSINESS DAY.

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

action in violation of this Section 10.9, the Property Trustee agrees, for the
benefit of Securityholders, that at the expense of the Depositor, it shall file
an answer with the bankruptcy court or otherwise properly contest the filing of
such petition by the Depositor against the Trust or the commencement of such
action and raise the defense that the Depositor has agreed in writing not to
take such action and should be stopped and precluded therefrom and such other
defenses, if any, as counsel for the Trustee or the Trust may assert. The

Re: ACE Capital Trust I _____% Trust Originated Preferred Securities

Ladies and Gentlemen:

     The purpose of this letter is to set forth certain matters relating to the
issuance and deposit with The Depository Trust Company ("DTC") of the ACE
Capital Trust I ____% Trust Originated Preferred Securities (the "Preferred
Securities"), of ACE Capital Trust I, a Delaware business trust (the "Issuer"),
governed by an Amended and Restated Trust Agreement among ACE INA Holdings Inc.
("ACE INA") and The First National Bank of Chicago, as Property Trustee, Bank
One Delaware, Inc., as Delaware Trustee, and the Administrative Trustees named
therein. The payment of distributions on the Preferred Securities, and payments
due upon liquidation of Issuer or redemption of the Preferred Securities, to the
extent the Issuer has funds available for the payment thereof are guaranteed by
ACE Limited, a Cayman Islands company and the parent of ACE INA ("ACE"), to the
extent set forth in a Guarantee Agreement dated ______________, ____ by ACE with
respect to the Preferred Securities. ACE INA, ACE and the Issuer propose to sell
the Preferred Securities to certain Underwriters (the "Underwriters") pursuant
to an Underwriting Agreement dated __________, 1999 by and among the
Underwriters, the Issuer, ACE INA and ACE dated _____, ____, and the
Underwriters wish to take delivery of the Preferred Securities through DTC. The
First National Bank of Chicago is acting as transfer agent and registrar with
respect to the Preferred Securities (the "Transfer Agent and Registrar").

     To induce DTC to accept the Preferred Securities as eligible for deposit at
DTC, and to act in accordance with DTC's rules with respect to the Preferred
Securities, the Issuer, the Transfer Agent and Registrar and DTC agree among
each other as follows:

     (1) Prior to the closing of the sale of the Preferred Securities to the
Underwrites, which is expected to occur on or about _________________, there
shall be deposited with DTC one or more global certificates (individually and
collectively, the "Global Certificate") registered in the name of DTC's
Preferred Securities nominee, Cede & Co., representing an aggregate of Preferred
Securities and bearing the following legend:

     Unless this certificate is presented by an authorized representative of The
Depository Trust Company, a New York corporation ("DTC"), to the Issuer or its
agent for registration of transfer,


                                      B-1
<PAGE>

exchange, or payment, and any certificate issued is registered in the name of
Cede & Co. or in such other name as is requested by an authorized representative
of DTC (and any payment is made to Cede & Co. or to such other entity as is
requested by an authorized representative of DTC), ANY TRANSFER, PLEDGE, OR
OTHER USE HEREOF FOR VALUE OR OTHERWISE BY OR TO ANY PERSON IS WRONGFUL inasmuch
as the registered owner hereof, Cede & Co., has an interest herein.

     (2) The Amended and Restated Trust Agreement of the Issuer provides for the
voting by holders of the Preferred Securities under certain limited
circumstances. The Issuer shall establish a record date for such purposes and
shall, to the extent possible, give DTC notice of such record date not less than
15 calendar days in advance of such record date.

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

     (4) In the event of distribution on, or an offering or issuance of rights
with respect to, the Preferred Securities outstanding, the Issuer or the
Transfer Agent and Registrar shall send DTC a notice specifying: (a) the amount
of and conditions, if any, applicable to the payment of any such distribution or
any such offering or issuance of rights; (b) any applicable expiration or
deadline date, or any date by which any action on the part of the holders of
Preferred Securities is required; and (c) the date any required notice is to be
mailed by or on behalf of the Issuer to holders of Preferred Securities or
published by or on behalf of the Issuer (whether by mail or publication, the
"Publication Date"). Such notice shall be sent to DTC by a secure means (e.g.,
legible telecopy, registered or certified mail, overnight delivery) in a timely
manner designed to assure that such notice is in DTC's possession no later than
the close of business on the business day before the Publication Date. The
Issuer or the Transfer Agent and Registrar will forward such notice either in a
separate secure transmission for each CUSIP number or in a secure transmission
of multiple CUSIP numbers (if applicable) that includes a manifest or list of
each CUSIP number submitted in that transmission. (The party sending such notice
shall have a method to verify subsequently the use of such means and the
timeliness of such notice.) The Publication Date shall be not less than 30
calendar days nor more than 60 calendar days prior to the payment of any such
distribution or any such offering or issuance of rights with respect to the
Preferred Securities. After establishing the amount of payment to be made on the
Preferred Securities, the Issuer or the Transfer Agent and Registrar will notify

     (10) In the event of a conversion, redemption, or any other similar

aggregate number of Preferred Securities outstanding evidenced by Global
Certificates, DTC, in its discretion: (a) may request the Issuer or the Transfer

     (11) DTC may discontinue its services as a securities depositary with

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

Certificate, duly endorsed for transfer as directed by the Issuer or the

     (b) So long as this Trust Agreement remains in effect, the Trust (or the
Trustees acting on behalf of the Trust) shall not undertake any business,
activities or transaction except as expressly provided herein or contemplated
hereby. In particular, the Trustees shall not cause the Trust to (i) acquire any
investments or engage in any activities not authorized by this Trust Agreement,
(ii) sell, assign, transfer, exchange, mortgage, pledge, set-off or otherwise
dispose of any of the Trust Property or interests therein, including to
Securityholders, except as expressly provided herein, (iii) take any action that
would cause the Trust to fail or cease to qualify as a "grantor trust" for
United States Federal income tax purposes, (iv) incur any indebtedness for
borrowed money or issue any other debt or (v) take or consent to any action that
would result in the placement of a Lien on any of the Trust Property. The
Administrative Trustees shall defend all claims and demands of all Persons at
any time claiming any Lien on any of the Trust Property adverse to the interest
of the Trust or the Securityholders in their capacity as Securityholders.

     (c) In connection with the issue and sale of the Preferred Securities, the
Depositor shall have the right and responsibility to assist the Trust with
respect to, or effect on behalf of the Trust, the following (and any actions
taken by the Depositor in furtherance of the following prior to the date of this
Trust Agreement are hereby ratified and confirmed in all respects):

          (i) the preparation and filing by the Trust with the Commission and
     the execution on behalf of the Trust of a registration statement on the
     appropriate form in relation to the Preferred Securities, including any
     amendments thereto;

          (ii) the determination of the States in which to take appropriate
     action to qualify or register for sale all or part of the Preferred
     Securities and the determination of any and all such acts, other than
     actions which must be taken by or on behalf of the Trust, and the advice to
     the Trustees of actions they must take on behalf of the Trust, and the
     preparation


                                       14
<PAGE>

     for execution and filing of any documents to be executed and filed by the
     Trust or on behalf of the Trust, as the Depositor deems necessary or
     advisable in order to comply with the applicable laws of any such States;

          (iii) the preparation for filing by the Trust and execution on behalf
     of the Trust of an application to the New York Stock Exchange or any other
     national stock exchange or the Nasdaq National Market for listing upon
     notice of issuance of any Preferred Securities;

          (iv) the preparation for filing by the Trust with the Commission and
     the execution on behalf of the Trust of a registration statement on Form
     8-A relating to the registration of the Preferred Securities under Section
     12(b) or 12(g) of the Exchange Act, including any amendments thereto;

          (v) the negotiation of the terms of, and the execution and delivery
     of, the Underwriting Agreement providing for the sale of the Preferred
     Securities; and

          (vi) the taking of any other actions deemed by the Depositor to be
     necessary or desirable to carry out any of the foregoing activities.

     (d) Notwithstanding anything herein to the contrary, the Administrative
Trustees are authorized and directed to conduct the affairs of the Trust and to
operate the Trust so that the Trust will not be deemed to be an "investment
company" required to be registered under the Investment Company Act or
classified as an association taxable as a corporation for United States Federal
income tax purposes and so that the Debentures will be treated as indebtedness
of the Debenture Issuer for United States Federal income tax purposes. In this
connection, the Depositor and the Administrative Trustees are authorized to take
any action, not inconsistent with applicable law, the Certificate of Trust or
this Trust Agreement, that each of the Depositor and the Administrative Trustees
determines in their discretion to be necessary or desirable for such purposes,
as long as such action does not adversely affect in any material respect the
interests of the Holders of the Preferred Securities.

     Section 2.8 ASSETS OF TRUST.

     The assets of the Trust shall consist of the Trust Property.

     Section 2.9 TITLE TO TRUST PROPERTY.

                                 PAYMENT ACCOUNT

     Section 3.1 PAYMENT ACCOUNT.

     (a) On or prior to the Closing Date, the Property Trustee shall establish
the Payment Account. The Property Trustee and any agent of the Property Trustee
shall have exclusive control and sole right of withdrawal with respect to the
Payment Account for the purpose of making deposits in and withdrawals from the
Payment Account in accordance with this Trust Agreement. All monies and other
property deposited or held from time to time in the Payment Account shall be
held by the Property Trustee in the Payment Account for the exclusive benefit of
the Securityholders and for distribution as herein provided, including (and
subject to) any priority of payments provided for herein.

     (b) The Property Trustee shall deposit in the Payment Account, promptly
upon receipt, all payments of principal of or interest on, and any other
payments or proceeds with respect to, the Debentures. Amounts held in the
Payment Account shall not be invested by the Property Trustee pending
distribution thereof.

                                  ARTICLE IV.

                      CERTAIN TERMS OF THE TRUST SECURITIES

     Section 4.1 DISTRIBUTIONS.

     (a) Distributions on the Trust Securities shall be cumulative, and will
accumulate whether or not there are funds of the Trust available for the payment
of Distributions. Distributions shall accrue from __________, ____, and shall be
payable quarterly in arrears on _________, _______, ______ and ________ of each
year, commencing on __________, _____, except as otherwise described below. The
Debenture Issuer has the right under the Indenture, at any time and from time to
time, to defer payments of interest for such period or periods as may be
specified with respect to the Debentures (each, an "Extension Period"), on the
terms and conditions specified in the Indenture. As a consequence of such
deferral, Distributions will also be deferred. Despite such deferral, quarterly
Distributions will continue to accumulate at the rate set forth in paragraph (b)
of this Section 4.1, together with additional distributions thereon (to the
extent permitted by applicable law) at the rate at which Additional Interest is
then accruing on the Debentures, compounded quarterly during any such Extension
Period. If any date on which a Distribution is otherwise payable on the Trust
Securities is not a Business Day, then the payment of such Distribution shall be
made on the next succeeding day that is a Business Day (and without any
additional distributions or other payment in respect of any such delay), except
that, if such Business Day is in the next succeeding calendar year, payment of
such Distribution shall be made on the immediately preceding Business Day, in
each case with the same force and effect as if made on the date such payment was
originally payable (each date on which distributions are payable in accordance
with this Section 4.1(a), a "Distribution Date").



                                       16
<PAGE>

     (b) The Trust Securities represent undivided beneficial interests in the
Trust Property, and, as a practical matter, the Distributions on the Trust
Securities shall be payable at a rate of __% per annum of the Liquidation Amount
of the Trust Securities. The term "Distributions" as used herein includes such
cash distributions and any accumulated or additional distributions that are
payable hereunder unless otherwise stated. The amount of Distributions payable
for any full or partial period shall be computed on the basis of a 360-day year
of twelve 30-day months. The amount of Distributions payable for any period
shall include Additional Amounts, if any.

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

     (d) Distributions on the Trust Securities with respect to a Distribution
Date shall be payable to the Holders thereof as they appear on the Securities
Register at the close of business on the relevant record date, which, as long as
the Preferred Securities remain in book-entry only form, shall be the date one
Business Day immediately preceding such Distribution Date. The relevant record
dates for the Common Securities shall be the same record dates as for the
Preferred Securities. If the Preferred Securities shall not continue to remain
in book-entry only form or are not in book-entry only form at issuance, the
relevant record dates for the Preferred Securities shall be the date 15 days
prior to the relevant Distribution Date, which Distribution Dates shall
correspond to the interest payment dates on the Debentures. Distributions
payable on any Trust Securities that are not punctually paid on any Distribution
Date, as a result of the Debenture Issuer (or the Debenture Guarantor on its
behalf) having failed to make an interest payment under the 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 for determining
Debentureholders entitled to such defaulted interest established in accordance
with the Indenture.

     (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 among the Holders of the Trust Securities. A reference
herein 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, a Debenture Event of Default 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.

     Section 4.2 REDEMPTION.

     (a) On each Debenture Redemption Date and on the stated maturity of the
Debentures, the Trust will be required to redeem a Like Amount of Trust
Securities at a price per Trust Security equal to the Redemption Price.

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

          (i) the Redemption Date;

          (ii) the Redemption Price;

          (iii) the CUSIP number;

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

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

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

     (d) If the Property Trustee gives a notice of redemption (which notice
shall be irrevocable) in respect of any Preferred Securities, then, by 12:00
noon, New York City time, on the Redemption Date, subject to Section 4.2(c), the
Property Trustee will, so long as the Preferred Securities are in
book-entry-only form, irrevocably deposit with the Clearing Agency for the
Preferred Securities funds sufficient to pay the applicable Redemption Price and
will give such Clearing Agency irrevocable instructions and authority to pay the
Redemption Price to the relevant Persons' accounts at such Clearing Agency on
the applicable Redemption Date. If the Preferred Securities are no longer in
book-entry-only form, and in the case of the Common Securities, the Property
Trustee, subject to Section 4.2(c), will irrevocably deposit with the Paying
Agent funds sufficient to pay the applicable Redemption Price and will give the
Paying Agent irrevocable instructions and authority to pay the Redemption Price
to the Holders thereof upon surrender of their Trust Securities Certificates.
Notwithstanding the foregoing, Distributions payable on or prior to the
Redemption Date for any Trust Securities called for redemption shall be payable
to the Holders of such Trust Securities as they appear on the Securities
Register for the Trust Securities


                                       18
<PAGE>

on the relevant record dates for the related Distribution Dates. If notice of
redemption shall have been given and funds deposited as required, then
immediately prior to the close of business on the date of such deposit, all
rights of Securityholders holding Trust Securities so called for redemption will
cease, except the right of such Securityholders to receive the Redemption Price
and any Distributions payable on or prior to the Redemption Date, but without
interest, and such Securities will cease to be outstanding. In the event that
any date on which any Redemption Price is payable is not a Business Day, then
payment of the Redemption Price payable on such date will be made on the next
succeeding day that is a Business Day (and without any interest or other payment
in respect of any such delay), except that, if such Business Day falls in the
next calendar year, such payment will be made on the immediately preceding
Business Day, in each case, with the same force and effect as if made on such
date. In the event that payment of the Redemption Price in respect of any Trust
Securities called for redemption is improperly withheld or refused and not paid
either by the Trust or by the Preferred Securities Guarantor pursuant to the
Guarantee, Distributions on such Trust Securities will continue to accrue, at
the then applicable rate, from the Redemption Date originally established by the
Trust for such Trust Securities to the date such Redemption Price is actually
paid, in which case the actual payment date will be the date fixed for
redemption for purposes of calculating the Redemption Price.

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

     (f) Subject to Section 4.3(a), if less than all the Outstanding Trust
Securities are to be redeemed on a Redemption Date, then the aggregate
Liquidation Amount of Trust Securities to be redeemed shall be allocated on a
pro rata basis (based on Liquidation Amounts) among the Common Securities and
the Preferred Securities. The particular Preferred Securities to be redeemed
shall be selected on a pro rata basis (based upon Liquidation Amounts) not more
than 60 days prior to the Redemption Date by the Property Trustee from the
Outstanding Preferred Securities not previously called for redemption, by such
method (including, without limitation, by lot) as the Property Trustee shall
deem fair and appropriate and which may provide for the selection for redemption
of portions (equal to $____ or an integral multiple of $____ in excess thereof)
of the Liquidation Amount of Preferred Securities of a denomination larger than
$____. The Property Trustee shall promptly notify the Security Registrar in
writing of the Preferred Securities selected for redemption and, in the case of
any Preferred Securities selected for partial redemption, the Liquidation Amount
thereof to be redeemed. For all purposes of this Trust Agreement, unless the
context otherwise requires, all provisions relating to the redemption of
Preferred Securities shall relate, in the case of any Preferred Securities
redeemed or to be redeemed only in part, to the portion of the Liquidation
Amount of Preferred Securities that has been or is to be redeemed.

     Section 4.3 SUBORDINATION OF COMMON SECURITIES.

     (a) Payment of Distributions (including Additional Amounts, if applicable)
on, and the Redemption Price of, the Trust Securities, as applicable, shall be
made, subject to Section 4.2(f), pro rata among the Common Securities and the
Preferred Securities based on the Liquidation Amount of the Trust Securities;
provided, however, that if on any Distribution Date or Redemption Date any Event
of Default resulting from a Debenture Event of Default shall have occurred and
be continuing, no payment of any Distribution (including Additional Amounts, if
applicable) on, or Redemption Price of, any Common Security, and no other
payment on account of the redemption, liquidation or other acquisition of Common
Securities, shall be made unless payment in full in cash of all accumulated and
unpaid Distributions (including Additional Amounts, if applicable) on all
Outstanding Preferred Securities for all Distribution periods terminating on or
prior thereto, or in the case of payment of the Redemption Price the full amount
of such Redemption Price on all Outstanding Preferred Securities, shall have
been made or provided for, and all funds immediately available to the Property
Trustee shall first be applied to the payment in full in cash of all
Distributions (including Additional Amounts, if applicable) on, or the
Redemption Price of, Preferred Securities then due and payable.

     (b) In the case of the occurrence of any Event of Default resulting from
any Debenture Event of Default, the Holder of Common Securities will be deemed
to have waived any right to act with respect to any such Event of Default under
this Trust Agreement until the effect of all such Events of Default with respect
to the Preferred Securities have been cured, waived or otherwise eliminated.
Until any such Event of Default under this Trust Agreement with respect to the
Preferred Securities has 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.

     Section 4.4 PAYMENT PROCEDURES.

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

     Section 4.5 TAX RETURNS AND REPORTS.

     The Administrative Trustees shall prepare (or cause to be prepared), at the

     (a) prepare and file (or cause to be prepared and filed) the appropriate
Internal Revenue Service Form required to be filed in respect of the Trust in
each taxable year of the Trust and

     (b) prepare and furnish (or cause to be prepared and furnished) to each
Securityholder the appropriate Internal Revenue Service form required to be
provided on such form. The Administrative Trustees shall provide the Depositor
and the Property Trustee with a copy of all such returns and reports promptly
after such filing or furnishing. The Trustees shall comply with United States
Federal withholding and backup withholding tax laws and information reporting
requirements with respect to any payments to Securityholders under the Trust
Securities.

     Section 4.6 PAYMENT OF TAXES, DUTIES, ETC. OF THE TRUST.

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

     Section 4.7 PAYMENTS UNDER INDENTURE.

     Any amount payable hereunder to any Holder of Preferred Securities shall be
reduced by the amount of any corresponding payment such Holder (and any Owner
with respect thereto) has directly received pursuant to Section 5.8 of the
Indenture.

                                   ARTICLE V.

     Section 5.1 INITIAL OWNERSHIP.

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

     Section 5.2 THE TRUST SECURITIES CERTIFICATES.

     The Preferred Securities Certificates shall be issued in minimum
denominations of $____ Liquidation Amount and integral multiples of $____ in
excess thereof, and the Common Securities Certificates shall be issued in

the Trust by manual signature of at least one Administrative Trustee. Trust
Securities Certificates bearing the manual signatures of individuals who were,
at the time when such signatures shall have been affixed, authorized to sign on
behalf of the Trust, shall be validly issued and entitled to the benefits of
this Trust Agreement, notwithstanding that such individuals or any of them shall
have ceased to be so authorized prior to the delivery of such Trust Securities
Certificates or did not hold such offices at the date of delivery of such Trust
Securities Certificates. A transferee of a Trust Securities Certificate shall
become a Securityholder, and shall be entitled to the rights and subject


                                       21
<PAGE>

to the obligations of a Securityholder hereunder, upon due registration of such
Trust Securities Certificate in such transferee's name pursuant to Sections 5.4,
5.11 and 5.13.

     Section 5.3 EXECUTION AND DELIVERY OF TRUST SECURITIES CERTIFICATES.

     At each Time of Delivery, the Administrative Trustees shall cause Trust
Securities Certificates, in an aggregate Liquidation Amount as provided in
Sections 2.4 and 2.5, to be executed on behalf of the Trust and delivered to or
upon the written order of the Depositor, signed by its Chairman of the Board, a
Vice Chairman, its President, a Vice President or its Treasurer and attested by
its Secretary or one of its Assistant Secretaries, without further corporate
action by the Depositor, in authorized denominations.

     Section 5.4 REGISTRATION OF TRANSFER AND EXCHANGE OF PREFERRED SECURITIES
CERTIFICATES.

     The Depositor shall keep or cause to be kept, at the office or agency
maintained pursuant to Section 5.8, a register or registers for the purpose of
registering Trust Securities Certificates and transfers and exchanges of
Preferred Securities Certificates (the "Securities Register"). The registrar
designated by the Depositor (the "Securities Registrar"), subject to such
reasonable regulations as it may prescribe, shall provide for the registration
of Preferred Securities Certificates and Common Securities Certificates (subject
to Section 5.10 in the case of the Common Securities Certificates) and
registration of transfers and exchanges of Preferred Securities Certificates as
herein provided. The Bank shall be the initial Securities Registrar. Upon
surrender for registration of transfer of any Preferred Securities Certificate
at the office or agency maintained pursuant to Section 5.8, the Administrative
Trustees or any one of them shall execute and deliver, in the name of the
designated transferee or transferees, one or more new Preferred Securities
Certificates in authorized denominations of a like aggregate Liquidation Amount
dated the date of execution by such Administrative Trustee or Trustees. The
Securities Registrar shall not be required to register the transfer of any
Preferred Securities after such Preferred Securities have been called for
redemption. At the option of a Holder, Preferred Securities Certificates may be
exchanged for other Preferred Securities Certificates in authorized
denominations of the same class and of a like aggregate Liquidation Amount upon
surrender of the Preferred Securities Certificates to be exchanged at the office
or agency maintained pursuant to Section 5.8. Every Preferred Securities
Certificate presented or surrendered for registration of transfer or exchange

Certificate surrendered for registration of transfer or exchange shall be

Preferred Securities Certificates shall be effected without service charge by or
on behalf of the Trust, but the Securities Registrar may require payment of a
sum sufficient to cover any tax or other governmental charge that may be imposed
in connection with any such transfer or exchange.

     Section 5.5 MUTILATED, DESTROYED, LOST OR STOLEN TRUST SECURITIES
CERTIFICATES.

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

     Section 5.6 PERSONS DEEMED SECURITYHOLDERS.

     Prior to due presentation of a Trust Securities Certificate for
registration of transfer, the Administrative Trustees or the Securities
Registrar shall treat the Person in whose name any Trust Securities Certificate
shall be registered in the Securities Register as the owner of such Trust
Securities Certificate for the purpose of receiving distributions and for all
other purposes whatsoever, and neither the Trustees nor the Securities Registrar
shall be bound by any notice to the contrary.

     Section 5.7 ACCESS TO LIST OF SECURITYHOLDERS' NAMES AND ADDRESSES.

     The Administrative Trustees shall furnish or cause to be furnished (x) to
the Depositor, within 15 days after receipt by any Administrative Trustee of a
request therefor from the Depositor in writing and (y) to the Property Trustee,
promptly after receipt by any Administrative Trustee of a request therefor from
the Property Trustee in writing in order to enable the Property Trustee to
discharge its obligations under this Trust Agreement, a list, in such form as
the Depositor or the Property Trustee may reasonably require, of the names and
addresses of the Securityholders as of a recent date. If Holders of Trust
Securities Certificates evidencing ownership at such time and for the previous
six months of not less than 25% of the Outstanding aggregate Liquidation Amount
apply in writing to any Administrative Trustee, and such application states that
the applicants desire to communicate with other Securityholders with respect to
their rights under this Trust Agreement or under the Trust Securities
Certificates and such application is accompanied by a copy of the communication
that such applicants propose to transmit, then the Administrative Trustees
shall, within five Business Days after the receipt of such application, afford
such applicants access during normal business hours to the current list of
Securityholders. Each Holder, by receiving and holding a Trust Securities
Certificate, and each Owner shall be deemed to have agreed not to hold the


                                       23

Depositor, the Property Trustee or the Administrative Trustees accountable by
reason of the disclosure of its name and address, regardless of the source from
which such information was derived.

     Section 5.8 MAINTENANCE OF OFFICE OR AGENCY.

     The Administrative Trustees shall maintain in Chicago, Illinois, an office
or offices or agency or agencies where Preferred Securities Certificates may be
surrendered for registration of transfer or exchange and where notices and
demands to or upon the Trustees in respect of the Trust Securities and the Trust
Agreement may be served. The Administrative Trustees initially designate The
First National Bank of Chicago, One First National Plaza, Suite 0126, Chicago,
Illinois 60670-0126; Attention: Corporate Trust Department, as the principal
corporate trust office for such purposes. The Administrative Trustees shall give
prompt written notice to the Depositor and to the Securityholders of any change
in the location of the Securities Register or any such office or agency.

     Section 5.9 APPOINTMENT OF PAYING AGENT.

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

     Section 5.10 OWNERSHIP OF COMMON SECURITIES BY DEPOSITOR.

     At each Time of Delivery, the Depositor shall acquire and retain beneficial
and record ownership of all of the Common Securities then issued by the Trust,
in an amount equal to at least 3% of the total capital of the Trust, at the same
time as the Preferred Securities are issued and sold. The aggregate Liquidation
Amount of the Common Securities at any time shall not be less than 3% of the
total capital of the Trust. To the fullest extent permitted by law, other than a
transfer in connection with a consolidation or merger of the Depositor into
another corporation, or any conveyance, transfer or lease by the Depositor of
its properties and assets substantially as an entirety to any Person, pursuant
to Section 8.1 of the Indenture, any attempted transfer of the Common Securities
shall be void. The Administrative Trustees shall cause each Common Securities
Certificate issued to the Depositor to contain a legend stating "THIS
CERTIFICATE IS NOT TRANSFERABLE EXCEPT AS PROVIDED IN THE TRUST AGREEMENT (AS
DEFINED BELOW)".

     Section 5.11 BOOK-ENTRY PREFERRED SECURITIES CERTIFICATES; COMMON
SECURITIES CERTIFICATE.

     (a) The Preferred Securities Certificates, upon original issuance, will be
issued in the form of a typewritten Preferred Securities Certificate or
Certificates representing Book-Entry Preferred Securities Certificates, to be
delivered to DTC, the initial Clearing Agency, by, or on behalf of, the Trust.
Such Preferred Securities Certificate or Certificates shall initially be
registered on the Securities Register in the name of Cede & Co., the nominee of
the initial Clearing Agency, and no beneficial owner will receive a Definitive
Preferred Securities Certificate representing such beneficial owner's interest
in such Preferred Securities, except as provided in Section 5.13. Except for
Definitive Preferred Securities Certificates as specified herein, unless and
until Definitive Preferred Securities Certificates have been issued to
beneficial owners pursuant to Section 5.13:

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

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

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

          (iv) the rights of the Owners of the Book-Entry Preferred Securities
     Certificates shall be exercised only through the Clearing Agency and shall
     be limited to those established by law and agreements between such Owners
     and the Clearing Agency and/or the Clearing Agency Participants; provided,
     that solely for the purposes of determining whether the Holders of the
     requisite amount of Preferred Securities have voted on any


                                       25
<PAGE>

     matter provided for in this Trust Agreement, so long as Definitive
     Preferred Security Certificates have not been issued, the Trustees may
     conclusively rely on, and shall be protected in relying on, any written
     instrument (including a proxy) delivered to the Trustees by the Clearing
     Agency setting forth the Owners' votes or assigning the right to vote on
     any matter to any other Persons either in whole or in part. Pursuant to the
     Certificate Depository Agreement, unless and until Definitive Preferred
     Securities Certificates are issued pursuant to Section 5.13, the initial
     Clearing Agency will make book-entry transfers among the Clearing Agency
     Participants and receive and transmit payments on the Preferred Securities
     to such Clearing Agency Participants.

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

     Section 5.12 NOTICES TO CLEARING AGENCY.

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

     Section 5.13 DEFINITIVE PREFERRED SECURITIES CERTIFICATES.

     If (a) the Depositor advises the Trustees in writing that the Clearing
Agency is no longer willing or able to act as clearing agency with respect to
the Preferred Securities Certificates, and the Depositor fails to appoint a
qualified successor within 90 days, (b) the Depositor at its option advises the
Trustees in writing that it elects to terminate the book-entry system through
the Clearing Agency or (c) after the occurrence of a Debenture Event of Default,
Owners of Preferred Securities Certificates representing beneficial interests
aggregating at least a majority of the Liquidation Amount of the Outstanding
Preferred Securities advise the Property Trustee in writing that the
continuation of a book-entry system through the Clearing Agency is no longer in
the best interest of the Owners of Preferred Securities Certificates, then the
Property Trustee shall notify the Clearing Agency and the Clearing Agency shall
notify all Owners of Preferred Securities Certificates and the other Trustees of
the occurrence of any such event and of the availability of the Definitive
Preferred Securities Certificates to Owners of such class or classes, as
applicable, requesting the same. Upon surrender to the Property Trustee of the
typewritten Preferred Securities Certificate or Certificates representing the
Book Entry Preferred Securities Certificates by the Clearing Agency, accompanied
by registration instructions, the Administrative Trustees, or any one of them,
shall execute the Definitive Preferred Securities Certificates in accordance
with the instructions of the Clearing Agency. Neither the Securities Registrar
nor the Trustees shall be liable for any delay in delivery of such instructions
and may conclusively rely on, and shall be protected in relying on, such
instructions. Upon the issuance of Definitive Preferred Securities Certificates,
the Trustees shall recognize the Holders of the Definitive Preferred Securities
Certificates as Securityholders. The Definitive Preferred Securities
Certificates shall be printed, lithographed or engraved or may be produced in
any other manner as is reasonably acceptable to


                                       26
<PAGE>

the Administrative Trustees, as evidenced by the execution thereof by the
Administrative Trustees or any one of them.

     Section 5.14 RIGHTS OF SECURITYHOLDERS.

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

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

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

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

               (A) all overdue installments of interest (including any
          Additional Interest) on, and any other Additional Amounts with respect
          to, all of the Debentures,

               (B) the principal of and premium on any Debentures which have
          become due otherwise than by such declaration of acceleration and
          interest thereon and any Additional Amounts with respect thereto at
          the rate or rates borne by or provided for in the Debentures,



                                       27
<PAGE>

               (C) to the extent the payment of such interest or Additional
          Amounts is lawful, interest upon overdue installments of any interest
          and Additional Amounts at the rate or rates borne by or provided for
          in the Debentures, and

               (D) all sums paid or advanced by the Debenture Trustee under the
          Indenture and the reasonable compensation, expenses, disbursements and
          advances of the Debenture Trustee, its agents and counsel and all
          other amounts due the Debenture Trustee under the Indenture; and

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

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

     The Holders of not less than a majority in Liquidation Amount of the
Preferred Securities then Outstanding may, on behalf of the Holders of all the
Preferred Securities, waive any past default under the Indenture, except a
default (i) in the payment of principal of, any premium or interest (including
any Additional Interest) on, or any other Additional Amounts with respect to,
the Debentures or (ii) in respect of a covenant or provision which under the
Indenture cannot be modified or amended without the consent of the holder of
each outstanding Debenture.

     Upon receipt by the Property Trustee of written notice declaring such an
acceleration, or rescission and annulment thereof, by Holders of the Preferred
Securities all or part of which are represented by Book-Entry Preferred
Securities Certificates, a record date shall be established for determining
Holders of Outstanding Preferred Securities entitled to join in such notice,
which record date shall be at the close of business on the day the Property
Trustee receives such notice. The Holders on such record date, or their duly
designated proxies, and only such Persons, shall be entitled to join in such
notice, whether or not such Holders remain Holders after such record date;
provided, that, unless such declaration of acceleration, or rescission and
annulment, as the case may be, shall have become effective by virtue of the
requisite percentage having joined in such notice prior to the day which is 90
days after such record date, such notice of declaration of acceleration, or
rescission and annulment, as the case may be, shall automatically and without
further action by any Holder be canceled and of no further effect. Nothing in
this paragraph shall prevent a Holder, or a proxy of a Holder, from giving,
after expiration of such 90-day period, a new written notice of declaration of
acceleration, or rescission and annulment thereof, as the case may be, that is
identical to a written notice which has been canceled pursuant to the proviso to
the preceding sentence, in which event a new record date shall be established
pursuant to the provisions of this Section 5.14(b).

     (c) For so long as any Preferred Securities remain Outstanding, to the
fullest extent permitted by law and subject to the terms of this Trust Agreement
and the Indenture, any Holder of Preferred Securities shall have the right, upon
a Debenture Event of Default specified in Section


                                       28
<PAGE>

5.1(1) or 5.1(2) of the Indenture, to institute directly a proceeding against
the Debenture Issuer or the Debenture Guarantor, as the case may be, pursuant to
Section 5.8 of the Indenture, for enforcement of payment to such Holder of the
principal of, and any premium and (subject to the provisions of the Indenture)
interest (including any Additional Interest) on, and any other Additional
Amounts with respect to, such Debentures having a principal amount equal to the
Liquidation Amount of the Preferred Securities of such Holder (a "Direct
Action"). In connection with any such Direct Action, the rights of the Holders
of Common Securities will be subrogated to the rights of any Holder of Preferred
Securities to the extent of any payment made by the Debenture Issuer or the
Debenture Guarantor, as the case may be, to such Holder of Preferred Securities
as a result of such Direct Action. Except as set forth in Section 5.14(b) and
(c), or as otherwise contemplated by the Indenture, the Holders of Preferred
Securities shall have no right to exercise directly any right or remedy
available to the holders of, or in respect of, the Debentures.

                                  ARTICLE VI.

                    ACTS OF SECURITYHOLDERS; MEETINGS; VOTING

     Section 6.1 LIMITATIONS ON VOTING RIGHTS.

     (a) Except as provided in this Section, in Sections 5.14, 8.10 and 10.2 and
in the Indenture and as otherwise required by law, no Holder of Preferred
Securities shall have any right to vote or in any manner otherwise control the
administration, operation and management of the Trust or the obligations of the
parties hereto, nor shall anything herein set forth, or contained in the terms
of the Trust Securities Certificates, be construed so as to constitute the
Securityholders from time to time as partners or members of an association.

     (b) So long as any Debentures are held by the Property Trustee, the
Trustees shall not

          (i) direct the time, method and place of conducting any proceeding for
     any remedy available to the Debenture Trustee, or executing any trust or
     power conferred on the Debenture Trustee with respect to such Debentures,

          (ii) waive any past default which is waivable under Section 5.13 of
     the Indenture,

          (iii) exercise any right to rescind or annul a declaration that the
     principal of all the Debentures shall be due and payable, or

          (iv) consent to any amendment, modification or termination of the
     Indenture or the Debentures, where such consent shall be required,

without, in each case, obtaining the prior approval of the Holders of at least a
majority in Liquidation Amount of all Outstanding Preferred Securities;
provided, however, that where a consent under the Indenture would require the
consent of each holder of Debentures affected thereby, no such consent shall be
given by the Property Trustee without the prior written consent of


                                       29
<PAGE>

each Holder of Preferred Securities. The Trustees shall not revoke any action
previously authorized or approved by a vote of the Holders of Preferred
Securities, except by a subsequent vote of the Holders of Preferred Securities.
The Property Trustee shall notify all Holders of the Preferred Securities of any
notice of default received from the Debenture Trustee with respect to the
Debentures. In addition to obtaining the foregoing approvals of the Holders of
the Preferred Securities, prior to taking any of the foregoing actions, the
Trustees shall, at the expense of the Depositor, obtain an Opinion of Counsel
rendered by counsel experienced in such matters to the effect that the Trust
will not be classified as an association taxable as a corporation for United
States Federal income tax purposes on account of such action.

     (c) If any proposed amendment to the Trust Agreement provides for, or the
Trustees otherwise propose to effect,

          (i) any action that would adversely affect in any material respect the
     powers, preferences or special rights of the Preferred Securities, whether
     by way of amendment to the Trust Agreement or otherwise, or

          (ii) the dissolution, winding-up or termination of the Trust, other
     than pursuant to the terms of this Trust Agreement, then the Holders of
     Outstanding Preferred Securities as a class will be entitled to vote on
     such amendment or proposal and such amendment or proposal shall not be
     effective except with the approval of the Holders of at least a majority in
     Liquidation Amount of the Outstanding Preferred Securities. No amendment to
     this Trust Agreement may be made if, as a result of such amendment, the
     Trust would be classified as an association taxable as a corporation for
     United States federal income tax purposes.

     Section 6.2 NOTICE OF MEETINGS.

     Notice of all meetings of the Preferred Securityholders, stating the time,
place and purpose of the meeting, shall be given by the Property Trustee
pursuant to Section 10.8 to each Preferred Securityholder of record, at his
registered address, at least 15 days and not more than 90 days before the
meeting. At any such meeting, any business properly before the meeting may be so
considered whether or not stated in the notice of the meeting. Any adjourned
meeting may be held as adjourned without further notice.

     Section 6.3 MEETINGS OF PREFERRED SECURITYHOLDERS.

     No annual meeting of Securityholders is required to be held. The
Administrative Trustees, however, shall call a meeting of Securityholders to
vote on any matter upon the written request of the Preferred Securityholders of
record of 25% of the Preferred Securities (based upon their Liquidation Amount)
and the Administrative Trustees or the Property Trustee may, at any time in
their discretion, call a meeting of Preferred Securityholders to vote on any
matters as to which Preferred Securityholders are entitled to vote. Preferred
Securityholders of record of 50% of the Outstanding Preferred Securities (based
upon their Liquidation Amount), present in person or by proxy, shall constitute
a quorum at any meeting of Securityholders. If a quorum is present at a


                                       30
<PAGE>

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

     Section 6.4 VOTING RIGHTS.

     Securityholders shall be entitled to one vote for each $____ of Liquidation
Amount represented by their Trust Securities in respect of any matter as to
which such Securityholders are entitled to vote.

     Section 6.5 PROXIES, ETC.

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

     Section 6.6 SECURITYHOLDER ACTION BY WRITTEN CONSENT.

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

     Section 6.7 RECORD DATE FOR VOTING AND OTHER PURPOSES.

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


                                       31
<PAGE>

distribution or other action, as the case may be, as a record date for the
determination of the identity of the Securityholders of record for such
purposes.

     Section 6.8 ACTS OF SECURITYHOLDERS.

     Any request, demand, authorization, direction, notice, consent, waiver or
other action provided or permitted by this Trust Agreement to be given, made or
taken by Securityholders or Owners may be embodied in and evidenced by one or
more instruments of substantially similar tenor signed by such Securityholders
or Owners in person or by an agent duly appointed in writing; and, except as
otherwise expressly provided herein, such action shall become effective when
such instrument or instruments are delivered to an Administrative Trustee. Such
instrument or instruments (and the action embodied therein and evidenced
thereby) are herein sometimes referred to as the "Act" of the Securityholders or
Owners signing such instrument or instruments. Proof of execution of any such
instrument or of a writing appointing any such agent shall be sufficient for any
purpose of this Trust Agreement and (subject to Section 8.1) conclusive in favor
of the Trustees, if made in the manner provided in this Section. The fact and
date of the execution by any Person of any such instrument or writing may be
proved by the affidavit of a witness of such execution or by a certificate of a
notary public or other officer authorized by law to take acknowledgments of
deeds, certifying that the individual signing such instrument or writing
acknowledged to him the execution thereof. Where such execution is by a signer
acting in a capacity other than his individual capacity, such certificate or
affidavit shall also constitute sufficient proof of his authority. The fact and
date of the execution of any such instrument or writing, or the authority of the
Person executing the same, may also be proved in any other manner which any
Trustee receiving the same deems sufficient. The ownership of Preferred
Securities shall be proved by the Securities Register. Any request, demand,
authorization, direction, notice, consent, waiver or other Act of the
Securityholder of any Trust Security shall bind every future Securityholder of
the same Trust Security and the Securityholder of every Trust Security issued
upon the registration of transfer thereof or in exchange therefor or in lieu
thereof in respect of anything done, omitted or suffered to be done by the
Trustees or the Trust in reliance thereon, whether or not notation of such
action is made upon such Trust Security. Without limiting the foregoing, a
Securityholder entitled hereunder to take any action hereunder with regard to
any particular Trust Security may do so with regard to all or any part of the
Liquidation Amount of such Trust Security or by one or more duly appointed
agents each of which may do so pursuant to such appointment with regard to all
or any part of such Liquidation Amount. If any dispute shall arise between the
Securityholders and the Administrative Trustees or among such Securityholders or
Trustees with respect to the authenticity, validity or binding nature of any
request, demand, authorization, direction, consent, waiver or other Act of such
Securityholder or Trustee under this Article VI, then the determination of such
matter by the Property Trustee shall be conclusive with respect to such matter.

     Section 6.9 INSPECTION OF RECORDS.

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

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

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

     (a) the Trust Securities Certificates issued at each Time of Delivery on
behalf of the Trust have been duly authorized and will have been, duly and
validly executed, issued and delivered by the Trustees pursuant to the terms and
provisions of, and in accordance with the requirements of, this Trust Agreement
and the Securityholders will be, as of each such date, entitled to the benefits
of this Trust Agreement; and

     (b) there are no taxes, fees or other governmental charges payable by the
Trust (or the Trustees on behalf of the Trust) under the laws of the State of
Delaware or any political subdivision thereof in connection with the execution,
delivery and performance by the Property Trustee or the Delaware Trustee, as the
case may be, of this Trust Agreement.

                                 ARTICLE VIII.

                                  THE TRUSTEES

     Section 8.1 CERTAIN DUTIES AND RESPONSIBILITIES.

     (a) The duties and responsibilities of the Trustees shall be as provided by
this Trust Agreement and, in the case of the Property Trustee, subject to the
Trust Indenture Act. Notwithstanding the foregoing, no provision of this Trust
Agreement shall require the Trustees to expend or risk their own funds or
otherwise incur any financial liability in the performance of any


                                       34
<PAGE>

of their duties hereunder, or in the exercise of any of their rights or powers,
if they shall have reasonable grounds for believing that repayment of such funds
or adequate indemnity against such risk or liability is not reasonably assured
to it. Whether or not therein expressly so provided, every provision of this
Trust Agreement relating to the conduct or affecting the liability of or
affording protection to the Trustees shall be subject to the provisions of this
Section. To the extent that, at law or in equity, an Administrative Trustee has
duties (including fiduciary duties) and liabilities relating thereto to the
Trust or to the Securityholders, such Administrative Trustee shall not be liable
to the Trust or to any Securityholder for such Trustee's good faith reliance on
the provisions of this Trust Agreement. The provisions of this Trust Agreement,
to the extent that they restrict the duties and liabilities of the
Administrative Trustees otherwise existing at law or in equity, are agreed by
the Depositor and the Securityholders to replace such other duties and
liabilities of the Administrative Trustees.

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

     (c) No provision of this Trust Agreement shall be construed to relieve the
Property Trustee from liability for its own bad faith, negligence or willful
misconduct, except that: (i) the Property Trustee undertakes to perform only
those duties specifically set forth in this Agreement, provided that, it must
exercise the same degree of care as a prudent person would exercise in the
conduct of his or her own affairs; (ii) the Property Trustee shall not be liable
for any error of judgment made in good faith by an authorized officer of the
Property Trustee, unless it shall be proved that the Property Trustee was
negligent in ascertaining the pertinent facts; (iii) 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; (iv) the Property Trustee's sole duty with
respect to the custody, safe keeping and physical preservation of the Debentures
and the Payment Account shall be to deal with such Property in a similar manner
as the Property Trustee deals with similar property for its own account, subject
to the protections and limitations on liability afforded to the Property Trustee
under this Trust Agreement and the Trust Indenture Act; (v) the Property Trustee
shall not be liable for any interest on any money received by it except as it
may otherwise agree with the Depositor; and money held by the Property Trustee
need not be segregated from other funds held by it except in relation to the
Payment Account maintained by the Property Trustee pursuant to Section 3.1 and
except to the extent otherwise required by law; and (vi) the Property


                                       35
<PAGE>

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

     Section 8.2 CERTAIN NOTICES.

     Within five (5) Business Days after the occurrence of any Event of Default
actually known to the Property Trustee, the Property Trustee shall transmit, in
the manner and to the extent provided in Section 10.8, notice of such Event of
Default to the Securityholders, the Administrative Trustees and the Depositor,
unless such Event of Default shall have been cured or waived. Within five
Business Days after the receipt of notice of the Debenture Issuer's exercise of
its right to defer the payment of interest on the Debentures pursuant to the
Indenture, the Administrative Trustees shall transmit, in the manner and to the
extent provided in Section 10.8, notice of such exercise to the Securityholders
and the Property Trustee, unless such exercise shall have been revoked.

     Section 8.3 CERTAIN RIGHTS OF PROPERTY TRUSTEE.

     Subject to the provisions of Section 8.1:

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

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



                                       36
<PAGE>

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

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

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

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

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

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

     (i) the Property Trustee may execute any of the trusts or powers hereunder
or perform any duties hereunder either directly or by or through its agents or
attorneys, provided that the Property Trustee shall be responsible for its own
negligence or recklessness with respect to selection of any agent or attorney
appointed by it hereunder;

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



                                       37
<PAGE>

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

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

     Section 8.4 NOT RESPONSIBLE FOR RECITALS OR ISSUANCE OF SECURITIES.

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

     Section 8.5 MAY HOLD SECURITIES.

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

     Section 8.6 COMPENSATION; INDEMNITY; FEES.

     The Depositor agrees:

     (a) to pay to the Trustees from time to time reasonable compensation for
all services rendered by them hereunder (which compensation shall not be limited
by any provision of law in regard to the compensation of a trustee of an express
trust);

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

     (c) to indemnify each of the Trustees or any predecessor Trustee for, and
to hold the Trustees harmless against, any loss, damage, claims, liability,
penalty or expense incurred without bad faith, negligence or willful misconduct
on its part, arising out of or in connection with the acceptance or
administration of this Trust Agreement, including the costs and expenses of
defending itself against any claim or liability in connection with the exercise
or performance of any of its powers or duties hereunder.



                                       38
<PAGE>

     The provisions of this Section 8.6 shall survive the termination of this
Trust Agreement or the resignation or removal of any Trustee. No Trustee may
claim any lien or charge on any Trust Property as a result of any amount due
pursuant to this Section 8.6.

     Section 8.7 CORPORATE PROPERTY TRUSTEE REQUIRED; ELIGIBILITY OF TRUSTEES.

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

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

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

     Section 8.8 CONFLICTING INTERESTS.

     If the Property Trustee has or shall acquire a conflicting interest within
the meaning of the Trust Indenture Act, the Property Trustee shall either
eliminate such interest or resign, to the extent and in the manner provided by,
and subject to the provisions of, the Trust Indenture Act and this Trust
Agreement. Subject to the foregoing, the Depositor and any Trustee 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 shall have no rights by virtue of this
Trust Agreement in and to such independent ventures or the income or profits
derived therefrom, and the pursuit of any such venture, even if competitive with
the business of the Trust, shall not be deemed wrongful or improper. Neither the
Depositor, nor any Trustee, shall be obligated to present any particular
investment or other opportunity to the Trust even if such opportunity is of a
character that, if presented to the Trust, could be taken by the Trust, and the
Depositor or any Trustee shall have the right to take for its own account
(individually or as a partner or fiduciary) or to recommend to others any such
particular investment or other opportunity. Any Trustee may engage in any
financial or other transaction with the Depositor or any Affiliate of the
Depositor, or may act as depository for, trustee or agent for, or act on any
committee or body of holders of, securities or other obligations of the
Depositor or its Affiliates.

     Section 8.9 CO-TRUSTEES AND SEPARATE TRUSTEE.

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

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

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

     (c) The Property Trustee at any time, by an instrument in writing executed
by it, with the written concurrence of the Depositor, may accept the resignation
of or remove any co-trustee or separate trustee appointed under this Section,
and, in case a Debenture Event of Default has occurred and is continuing, the
Property Trustee shall have power to accept the resignation of, or


                                       40
<PAGE>

remove, any such co-trustee or separate trustee without the concurrence of the
Depositor. Upon the written request of the Property Trustee, the Depositor shall
join with the Property Trustee in the execution, delivery and performance of all
instruments and agreements necessary or proper to effectuate such resignation or
removal. A successor to any co-trustee or separate trustee so resigned or
removed may be appointed in the manner provided in this Section.

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

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

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

     Section 8.10 RESIGNATION AND REMOVAL; APPOINTMENT OF SUCCESSOR.

     No resignation or removal of any Trustee (the "Relevant Trustee") and no
appointment of a successor Trustee pursuant to this Article shall become
effective until the acceptance of appointment by the successor Trustee in
accordance with the applicable requirements of Section 8.11. Subject to the
immediately preceding sentence, the Relevant Trustee may resign at any time with
respect to the Trust Securities by giving written notice thereof to the
Depositor. If the instrument of acceptance by the successor Trustee required by
Section 8.11 shall not have been delivered to the Relevant Trustee within 30
days after the giving of such notice of resignation, the Relevant Trustee may
petition, at the expense of the Depositor, any court of competent jurisdiction
for the appointment of a successor Relevant Trustee with respect to the Trust
Securities. Unless a Debenture Event of Default shall have occurred and be
continuing, any Trustee may be removed at any time by Act of the Common
Securityholder. If a Debenture Event of Default shall have occurred and be
continuing, the Property Trustee or the Delaware Trustee, or both of them, may
be removed at such time by Act of the Holders of a majority in Liquidation
Amount of the Preferred Securities, delivered to the Relevant Trustee (in its
individual capacity and on behalf of the Trust). In no event will the Holders of
Preferred Securities have the right to vote to appoint, remove or replace the
Administrative Trustees. An Administrative Trustee may be removed by Act of the
Common Securityholder at any time. If any Trustee shall resign, be removed or
become incapable of acting as Trustee, or if a vacancy shall occur in the office
of any Trustee for any cause, at a time when no Debenture Event of Default shall
have occurred and be continuing, the Common Securityholder, by Act of the Common
Securityholder delivered to the retiring Trustee, shall promptly appoint a
successor Trustee or Trustees with respect to the Trust Securities and the
Trust, and the retiring Trustee shall comply with the applicable requirements of
Section 8.11. If the Property Trustee or the Delaware Trustee shall resign, be
removed or become incapable of continuing to act as the Property Trustee or the
Delaware Trustee, as the case may be, at a time when a Debenture Event of
Default shall have occurred and be continuing, the Preferred Securityholders, by
Act of the Securityholders of a majority in Liquidation Amount of the Preferred
Securities then Outstanding delivered to the retiring Relevant Trustee, shall
promptly appoint a


                                       41
<PAGE>

successor Relevant Trustee or Trustees with respect to the Trust Securities and
the Trust, and such successor Trustee shall comply with the applicable
requirements of Section 8.11. If an Administrative Trustee shall resign, be
removed or become incapable of acting as Administrative Trustee, at a time when
a Debenture Event of Default shall have occurred and be continuing, the Common
Securityholder by Act of the Common Securityholder delivered to the
Administrative Trustee shall promptly appoint a successor Administrative Trustee
or Administrative Trustees with respect to the Trust Securities and the Trust,
and such successor Administrative Trustee or Trustees shall comply with the
applicable requirements of Section 8.11. If no successor Relevant Trustee with
respect to the Trust Securities shall have been so appointed by the Common
Securityholder or the Preferred Securityholders and accepted appointment in the
manner required by Section 8.11, any Securityholder who has been a
Securityholder of Trust Securities for at least six months may, on behalf of
himself and all others similarly situated, petition any court of competent
jurisdiction for the appointment of a successor Relevant Trustee with respect to
the Trust Securities. The Depositor shall give notice of each resignation and
each removal of the Property Trustee or the Delaware Trustee and each
appointment of a successor Property Trustee or Delaware Trustee to all
Securityholders in the manner provided in Section 10.8. Each notice shall
include the name of the successor Relevant Trustee and the address of its
Corporate Trust Office if it is the Property Trustee. Notwithstanding the
foregoing or any other provision of this Trust Agreement, in the event any
Administrative Trustee or a Delaware Trustee who is a natural person dies or
becomes, in the opinion of the Depositor, incompetent or incapacitated, the
vacancy created by such death, incompetence or incapacity may be filled by (a)
the unanimous act of remaining Administrative Trustees if there are at least two
of them or (b) otherwise by the Depositor (with the successor in each case being
a Person who satisfies the eligibility requirement for Administrative Trustees
set forth in Section 8.7).

     Section 8.11 ACCEPTANCE OF APPOINTMENT BY SUCCESSOR.

     In case of the appointment hereunder of a successor Trustee such successor
Trustee so appointed shall execute, acknowledge and deliver to the Trust and to
the retiring Trustee an instrument accepting such appointment, and thereupon the
resignation or removal of the retiring Trustee shall become effective and such
successor Trustee, without any further act, deed or conveyance, shall become
vested with all the rights, powers, trusts and duties of the retiring Trustee;
but, on the request of the Depositor or the successor Trustee, such retiring
Trustee shall, upon payment of its charges, execute and deliver an instrument
transferring to such successor Trustee all the rights, powers and trusts of the
retiring Trustee and if the Property Trustee is the resigning Trustee shall duly
assign, transfer and deliver to the successor Trustee all property and money
held by such retiring Property Trustee hereunder. In case of the appointment
hereunder of a successor Relevant Trustee with respect to the Trust Securities
and the Trust, the retiring Relevant Trustee and each successor Relevant Trustee
with respect to the Trust Securities shall execute and deliver an amendment
hereto wherein each successor Relevant Trustee shall accept such appointment and
which



                                       42
<PAGE>

     (a) shall contain such provisions as shall be necessary or desirable to
transfer and confirm to, and to vest in, each successor Relevant Trustee all the
rights, powers, trusts and duties of the retiring Relevant Trustee with respect
to the Trust Securities and the Trust and

     (b) shall add to or change any of the provisions of this Trust Agreement as
shall be necessary to provide for or facilitate the administration of the trusts
hereunder by more than one Relevant Trustee, it being understood that nothing
herein or in such amendment shall constitute such Relevant Trustees co-trustees
of the same trust and that each such Relevant Trustee shall be trustee of a
trust or trusts hereunder separate and apart from any trust or trusts hereunder
administered by any other such Relevant Trustee and upon the execution and
delivery of such amendment the resignation or removal of the retiring Relevant
Trustee shall become effective to the extent provided therein and each such
successor Relevant Trustee, without any further act, deed or conveyance, shall
become vested with all the rights, powers, trusts and duties of the retiring
Relevant Trustee with respect to the Trust Securities and the Trust; but, on
request of the Trust or any successor Relevant Trustee such retiring Relevant
Trustee shall duly assign, transfer and deliver to such successor Relevant
Trustee all Trust Property, all proceeds thereof and money held by such retiring
Relevant Trustee hereunder with respect to the Trust Securities and the Trust.
Upon request of any such successor Relevant Trustee, the Trust shall execute any
and all instruments for more fully and certainly vesting in and confirming to
such successor Relevant Trustee all such rights, powers and trusts referred to
in the first or second preceding paragraph, as the case may be. No successor
Relevant Trustee shall accept its appointment unless at the time of such
acceptance such successor Relevant Trustee shall be qualified and eligible under
this Article.

     Section 8.12 MERGER, CONVERSION, CONSOLIDATION OR SUCCESSION TO BUSINESS.

     Any corporation into which the Property Trustee or the Delaware Trustee (or
any Administrative Trustee that is not a natural person) may be merged or
converted or with which it may be consolidated, or any corporation resulting
from any merger, conversion or consolidation to which such Relevant Trustee
shall be a party, shall be the successor of such Relevant Trustee hereunder,
provided such corporation shall be otherwise qualified and eligible under this
Article, without the execution or filing of any paper or any further act on the
part of any of the parties hereto.

     Section 8.13 PREFERENTIAL COLLECTION OF CLAIMS AGAINST DEPOSITOR, DEBENTURE
ISSUER OR TRUST.

     If and when the Property Trustee or the Delaware Trustee shall be or become
a creditor of the Depositor, the Debenture Issuer or the Trust (or any other
obligor upon the Debentures or the Trust Securities), the Property Trustee or
the Delaware Trustee, as the case may be, shall be subject to and shall take all
actions necessary in order to comply with the provisions of the Trust Indenture
Act regarding the collection of claims against the Depositor, Debenture Issuer
or Trust (or any such other obligor).

     Section 8.14 REPORTS BY PROPERTY TRUSTEE.

     (a) Within 60 days after September 15 of each year commencing with the
first September 15 following the first issuance of Preferred Securities pursuant
to this Trust Agreement, the Property Trustee shall transmit to all
Securityholders in accordance with Section 10.8, and to the Depositor, a brief
report dated as of such September 15 with respect to: (i) its eligibility under
Section 8.7 or, in lieu thereof, if to the best of its knowledge it has
continued to be eligible under said Section, a written statement to such effect;
(ii) a statement that the Property Trustee has complied with all of its
obligations under this Trust Agreement during the twelve-month period (or, in
the case of the initial report, the period since the Closing Time) ending with
such September 15 or, if the Property Trustee has not complied in any material
respect with such obligations, a description of such noncompliance; and (iii)
any change in the property and funds in its possession as Property Trustee since
the date of its last report and any action taken by the Property Trustee in the
performance of its duties hereunder which it has not previously reported and
which in its opinion materially affects the Trust Securities.

     (b) In addition the Property Trustee shall transmit to Securityholders such
reports concerning the Property Trustee and its actions under this Trust
Agreement as may be required pursuant to the Trust Indenture Act at the times
and in the manner provided pursuant thereto.

     (c) A copy of each such report shall, at the time of such transmission to
Holders, be filed by the Property Trustee with each stock exchange, interdealer

     The Depositor and the Administrative Trustees on behalf of the Trust shall

Any certificate or opinion required to be given by an officer pursuant to
Section 314(c)(1) of the Trust Indenture Act shall be given in the form of an

<PAGE>

The Property Trustee and the Delaware Trustee may be the same person if the
Property Trustee meets the applicable requirements.

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

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

     Section 8.18 DELEGATION OF POWER.

the execution of such instruments either in the name of the Trust or the names
of the Administrative Trustees or otherwise as the Administrative Trustees may
deem expedient, to the extent such delegation is not prohibited by applicable
law or contrary to the provisions of the Trust, as set forth herein.

                                  ARTICLE IX.

                DISSOLUTION, LIQUIDATION, TERMINATION AND MERGER

     Section 9.1 DISSOLUTION UPON EXPIRATION DATE.

     Unless earlier dissolved, the Trust shall automatically dissolve on
December 31, 2054 (the "Expiration Date").

     Section 9.2 EARLY DISSOLUTION.

     The first to occur of any of the following events is an "Early Termination
Event", upon the occurrence of which the Trust shall be dissolved:

     (a) the occurrence of a Bankruptcy Event in respect of, or the dissolution
or liquidation of, the Debenture Issuer or the Debenture Guarantor;



                                       45
<PAGE>

     (b) the written direction to the Property Trustee from the Depositor at any
time (which direction is optional and wholly within the discretion of the
Depositor) to dissolve the Trust and distribute a Like Amount of Debentures to
Securityholders in exchange for the Trust Securities;

     (c) the redemption of all of the Trust Securities in connection with the
redemption of all the Debentures; and

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

     Section 9.3 TERMINATION.

     The respective obligations and responsibilities of the Trustees and the
Trust shall terminate upon the latest to occur of the following:

     (a) the distribution by the Property Trustee to Securityholders upon the
liquidation of the Trust pursuant to Section 9.4, or upon the redemption of all
of the Trust Securities pursuant to Section 4.2, of all amounts required to be
distributed hereunder upon the final payment of the Trust Securities;

     (b) the payment of any expenses owed by the Trust; and

     (c) the discharge of all administrative duties of the Administrative
Trustees, including the performance of any tax reporting obligations with
respect to the Trust or the Securityholders.

     Section 9.4 LIQUIDATION.

     (a) If an Early Termination Event specified in clause (a), (b), or (d) of
Section 9.2 occurs or upon the Expiration Date, the Trust shall be liquidated by
the Trustees as expeditiously as the Trustees determine to be possible by
distributing, after satisfaction of liabilities to creditors of the Trust as
provided by applicable law, to each Securityholder a Like Amount of Debentures,
subject to Section 9.4(e).

     (b) Notice of liquidation shall be given by the Property Trustee by
first-class mail, postage prepaid mailed not later than 30 nor more than 60 days
prior to the Liquidation Date to each Holder of Trust Securities at such
Holder's address appearing in the Securities Register. All notices of
liquidation shall: (i) state the Liquidation Date; (ii) state that from and
after the Liquidation Date, the Trust Securities will no longer be deemed to be
Outstanding and any Trust Securities Certificates not surrendered for exchange
will be deemed to represent a Like Amount of Debentures; and (iii) provide such
information with respect to the mechanics by which Holders may exchange Trust
Securities Certificates for Debentures, or if Section 9.4(e) applies, receive a
Liquidation Distribution, as the Administrative Trustees or the Property Trustee
shall deem appropriate.

     (c) Except where Section 9.2(c) or 9.4(e) applies, in order to effect the
liquidation of the Trust and distribution of the Debentures to Securityholders,
the Property Trustee shall establish a


                                       46
<PAGE>

record date for such distribution (which shall be not more than 45 days prior to
the Liquidation Date) and, either itself acting as exchange agent or through the
appointment of a separate exchange agent, shall establish such procedures as it
shall deem appropriate to effect the distribution of Debentures in exchange for
the Outstanding Trust Securities Certificates.

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

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

     Section 9.5 MERGERS, CONSOLIDATIONS, AMALGAMATIONS OR REPLACEMENTS OF THE
TRUST.

     The Trust may not merge with or into, convert into, consolidate,
amalgamate, or be replaced by, or convey, transfer or lease its properties and
assets substantially as an entirety to any corporation or other entity, except
pursuant to this Section 9.5 or Section 9.4. The Trust may, at the


                                       47
<PAGE>

request of the Depositor, with the consent of only the Administrative Trustees
and without the consent of the Holders of the Preferred Securities, merge with
or into, convert into, consolidate, amalgamate, or be replaced by or convey,
transfer or lease its properties and assets substantially as an entirety to a
trust organized as such under the laws of any State; provided, that (i) such
successor entity either (a) expressly assumes all of the obligations of the
Trust with respect to the Preferred Securities or (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 rank in priority with
respect to distributions and payments upon liquidation, redemption and
otherwise, (ii) the Depositor expressly appoints a trustee of such successor
entity possessing the same powers and duties as the Property Trustee as the
holder of the Debentures, (iii) the Successor Securities are listed or traded,
or any Successor Securities will be listed upon notification of issuance, on any
national securities exchange or other organization on which the Preferred
Securities are then listed or traded, if any, (iv) such merger, conversion,
consolidation, amalgamation, replacement, conveyance, transfer or lease does not
cause the Preferred Securities (including any Successor Securities) to be
downgraded by any nationally recognized statistical rating organization, (v)
such merger, conversion, consolidation, amalgamation, replacement, conveyance,
transfer or lease does not adversely affect the rights, preferences and
privileges of the Holders of the Preferred Securities (including any Successor
Securities) in any material respect, (vi) such successor entity has a purpose
substantially identical to that of the Trust, (vii) prior to such merger,
conversion, consolidation, amalgamation, replacement, conveyance, transfer or
lease, the Depositor has received an Opinion of Counsel rendered by independent
counsel experienced in such matters to the effect that (a) such merger,
conversion, consolidation, amalgamation, replacement, conveyance, transfer or
lease does not adversely affect the rights, preferences and privileges of the
Holders of the Preferred Securities (including any Successor Securities) in any
material respect, and (b) following such merger, conversion, consolidation,
amalgamation, replacement, conveyance, transfer or lease, neither the Trust nor
such successor entity will be required to register as an investment company
under the Investment Company Act and (viii) the Depositor (or any permitted
successor or assignee) owns all of the common securities of such successor
entity and guarantees the obligations of such successor entity under the
Successor Securities at least to the extent provided by the Guarantee.
Notwithstanding the foregoing, the Trust shall not, except with the consent of
holders of 100% in Liquidation Amount of the Preferred Securities, consolidate,
amalgamate, merge with or into, convert into, or be replaced by or convey,
transfer or lease its properties and assets substantially as an entirety to any
other entity or permit any other entity to consolidate, amalgamate, merge with
or into, convert into, or replace it if such consolidation, amalgamation,
merger, conversion, replacement, conveyance, transfer or lease would cause the
Trust or the successor entity to be classified as other than a grantor trust for
United States Federal income tax purposes.

                            MISCELLANEOUS PROVISIONS

     Section 10.1 LIMITATION OF RIGHTS OF SECURITYHOLDERS.

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

ambiguity, correct or supplement any provision herein which may be inconsistent
with any other provision herein, or to make any other provisions with respect to
matters or questions arising under this Trust Agreement, which shall not be
inconsistent with the other provisions of this Trust Agreement, or (ii) to
modify, eliminate or add to any provisions of this Trust Agreement to such
extent as shall be necessary to ensure that the Trust will be classified for
United States Federal income tax purposes as a grantor trust at all times that
any Trust Securities are outstanding or to ensure that the Trust will not be
required to register as an investment company under the Investment Company;
provided, however, that in the case of clause (i), such action shall not
adversely affect in any material respect the interests of any Securityholder.
Any such amendments of this Trust Agreement shall become effective when notice
thereof is given to the Securityholders.

     (b) Except as provided in Section 10.2(c) hereof, any provision of this
Trust Agreement may be amended by the Trustees and the Depositor with (i) the
consent of Trust Securityholders representing not less than a majority (based
upon Liquidation Amounts) of the Trust Securities then Outstanding and (ii)
receipt by the Trustees of an Opinion of Counsel to the effect that such
amendment or the exercise of any power granted to the Trustees in accordance
with such amendment will not affect the Trust's status as a grantor trust for
United States Federal income tax purposes or the Trust's exemption from status
of an investment company under the Investment Company Act.

     (c) In addition to and notwithstanding any other provision in this Trust
Agreement, without the consent of each affected Securityholder, this Trust
Agreement may not be amended to (i) change the amount or timing of any
Distribution on the Trust Securities or otherwise adversely affect the amount of
any Distribution required to be made in respect of the Trust Securities as of a
specified date or (ii) restrict the right of a Securityholder to institute suit
for the enforcement of any such payment on or after such date. Notwithstanding
any other provision herein, without the unanimous consent of the
Securityholders, this paragraph (c) of this Section 10.2 may not be amended.

     (d) Notwithstanding any other provisions of this Trust Agreement, no
Trustee shall enter into or consent to any amendment to this Trust Agreement

status of an investment company under the Investment Company Act or fail or
cease to be classified as a grantor trust for United States Federal income tax
purposes.

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

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

     (g) Neither the Property Trustee nor the Delaware Trustee shall be required

shall be entitled to receive an Opinion of Counsel and an Officers' Certificate
stating that any amendment to this Trust Agreement is in compliance with this
Trust Agreement.

     Section 10.3 SEPARABILITY.

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

     Section 10.4 GOVERNING LAW.

     This Trust Agreement and the rights and obligations of each of the
Securityholders, the Trust and the Trustees with respect to this Trust Agreement
and the Trust Securities shall be construed in accordance with and governed by
the laws of the State of Delaware.

     Section 10.5 PAYMENTS DUE ON NON-BUSINESS DAY.

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

     Section 10.6 SUCCESSORS.

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

                                       51
<PAGE>

action in violation of this Section 10.9, the Property Trustee agrees, for the
benefit of Securityholders, that at the expense of the Depositor, it shall file
an answer with the bankruptcy court or otherwise properly contest the filing of
such petition by the Depositor against the Trust or the commencement of such
action and raise the defense that the Depositor has agreed in writing not to
take such action and should be stopped and precluded therefrom and such other

Re:  ACE Capital Trust II _____% Trust Originated Preferred Securities

Ladies and Gentlemen:

     The purpose of this letter is to set forth certain matters relating to the
issuance and deposit with The Depository Trust Company ("DTC") of the ACE
Capital Trust II ____% Trust Originated Preferred Securities (the "Preferred
Securities"), of ACE Capital Trust II, a Delaware business trust (the "Issuer"),
governed by an Amended and Resated Trust Agreement among ACE INA Holdings Inc.
("ACE INA") and The First National Bank of Chicago, as Property Trustee, Bank
One Delaware, Inc., as Delaware Trustee, and the Administrative Trustees named
therein. The payment of distributions on the Preferred Securities, and payments
due upon liquidation of Issuer or redemption of the Preferred Securities, to the
extent the Issuer has funds available for the payment thereof are guaranteed by
ACE Limited, a Cayman Islands company and the parent of ACE INA ("ACE"), to the
extent set forth in a Guarantee Agreement dated ______________, ____ by ACE with
respect to the Preferred Securities. ACE INA, ACE and the Issuer propose to sell
the Preferred Securities to certain Underwriters (the "Underwriters") pursuant
to an Underwriting Agreement dated __________, 1999 by and among the
Underwriters, the Issuer, ACE INA and ACE dated _____, ____, and the
Underwriters wish to take delivery of the Preferred Securities through DTC. The
First National Bank of Chicago is acting as transfer agent and registrar with
respect to the Preferred Securities (the "Transfer Agent and Registrar").

     To induce DTC to accept the Preferred Securities as eligible for deposit at
DTC, and to act in accordance with DTC's rules with respect to the Preferred
Securities, the Issuer, the Transfer Agent and Registrar and DTC agree among
each other as follows:

     (1) Prior to the closing of the sale of the Preferred Securities to the
Underwrites, which is expected to occur on or about _________________, there
shall be deposited with DTC one or more global certificates (individually and
collectively, the "Global Certificate") registered in the name of DTC's
Preferred Securities nominee, Cede & Co., representing an aggregate of Preferred
Securities and bearing the following legend:

     Unless this certificate is presented by an authorized representative of The
Depository Trust Company, a New York corporation ("DTC"), to the Issuer or its
agent for registration of transfer,

                                      B-1
<PAGE>

exchange, or payment, and any certificate issued is registered in the name of
Cede & Co. or in such other name as is requested by an authorized representative
of DTC (and any payment is made to Cede & Co. or to such other entity as is
requested by an authorized representative of DTC), ANY TRANSFER, PLEDGE, OR
OTHER USE HEREOF FOR VALUE OR OTHERWISE BY OR TO ANY PERSON IS WRONGFUL inasmuch
as the registered owner hereof, Cede & Co., has an interest herein.

     (2) The Amended and Restated Trust Agreement of the Issuer provides for the
voting by holders of the Preferred Securities under certain limited
circumstances. The Issuer shall establish a record date for such purposes and
shall, to the extent possible, give DTC notice of such record date not less than
15 calendar days in advance of such record date.

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

     (4) In the event of distribution on, or an offering or issuance of rights
with respect to, the Preferred Securities outstanding, the Issuer or the
Transfer Agent and Registrar shall send DTC a notice specifying: (a) the amount
of and conditions, if any, applicable to the payment of any such distribution or
any such offering or issuance of rights; (b) any applicable expiration or
deadline date, or any date by which any action on the part of the holders of
Preferred Securities is required; and (c) the date any required notice is to be
mailed by or on behalf of the Issuer to holders of Preferred Securities or
published by or on behalf of the Issuer (whether by mail or publication, the
"Publication Date"). Such notice shall be sent to DTC by a secure means (e.g.,
legible telecopy, registered or certified mail, overnight delivery) in a timely
manner designed to assure that such notice is in DTC's possession no later than
the close of business on the business day before the Publication Date. The
Issuer or the Transfer Agent and Registrar will forward such notice either in a
separate secure transmission for each CUSIP number or in a secure transmission
of multiple CUSIP numbers (if applicable) that includes a manifest or list of
each CUSIP number submitted in that transmission. (The party sending such notice
shall have a method to verify subsequently the use of such means and the
timeliness of such notice.) The Publication Date shall be not less than 30
calendar days nor more than 60 calendar days prior to the payment of any such
distribution or any such offering or issuance of rights with respect to the
Preferred Securities. After establishing the amount of payment to be made on the
Preferred Securities, the Issuer or the Transfer Agent and Registrar will notify
DTC's Dividend Department of such payment 5 business days prior to payment date.

manner set forth in paragraph 4. Such redemption notice shall be sent to DTC's

such notice shall be confirmed by telephoning (516) 227-4070. Notice by mail or

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

Preferred Securities evidenced by the Global Certificate shall be received by
Cede & Co., as nominee of DTC, or its registered assigns in next day funds on
each payment date (or in accordance with existing arrangements between the
Issuer or the Transfer Agent and Registrar and DTC). Such payments shall be made
payable to the order of Cede & Co., and shall be addressed as follows:

     New York, New York 10004-2695.

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

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

     (11) DTC may discontinue its services as a securities depositary with
respect to the Preferred Securities at any time by giving at least 90 days'
prior written notice to the Issuer and the Transfer Agent and Registrar (at
which time DTC will confirm with the Issuer or the Transfer Agent and Registrar
the aggregate number of Preferred Securities deposited with it) and discharging
its responsibilities with respect thereto under applicable law. Under such
circumstances, the Issuer may determine to make alternative arrangements for
book-entry settlement for the Preferred Securities, make available one or more
separate global certificates evidencing Preferred Securities to any Participant
having Preferred Securities credited to its DTC account, or issue definitive
Preferred Securities to the beneficial holders thereof, and in any such case,
DTC agrees to cooperate fully with the Issuer and the Transfer Agent and
Registrar, and to return the Global Certificate, and the Transfer Agent and
Registrar, and to return the Global Certificate, duly endorsed for transfer as
directed by the Issuer or the Transfer Agent and Registrar, together with any
other documents of transfer reasonably requested by the Issuer of the Transfer
Agent and Registrar.

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

     payment of any sums paid under the Preferred Securities, under any
     Obligation, under the Guarantee Agreement dated the date hereof between
     ACE, in its capacity as guarantor with respect to the Preferred Securities,
     and The First National Bank of Chicago, as guarantee trustee, or under this
     Agreement for any reason whatsoever. This Agreement is continuing,
     irrevocable, unconditional and absolute.

     SECTION 1.3. WAIVER OF NOTICE.

from time to time of any of the following:

          (a) the extension of time for the payment by the Trust of all or any
     portion of the Obligations or for the performance of any other obligation
     under, arising out of, or in connection with, the Obligations;

          (b) any failure, omission, delay or lack of diligence on the part of
     the Beneficiaries to enforce, assert or exercise any right, privilege,
     power or remedy conferred on the Beneficiaries with respect to the
     Obligations or any action on the part of the Trust granting indulgence or
     extension of any kind;

          (c) 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 of, or other similar proceedings affecting, the Trust
     or any of the assets of the Trust.

There shall be no obligation of the Beneficiaries to give notice to, or obtain
the consent of, ACE with respect to the happening of any of the foregoing.

     SECTION 1.5. ENFORCEMENT.

     A Beneficiary may enforce this Agreement directly against ACE and ACE
waives any right or remedy to require that any action be brought against the
Trust or any other person or entity before proceeding against ACE.

     SECTION 1.6. SUBROGATION.

     ACE shall be subrogated to all (if any) rights of the Trust in respect of
any amounts paid to the Beneficiaries by ACE under this Agreement; provided,

Trustee, on behalf of the Trust, shall subscribe to and purchase from the
Debenture Issuer Debentures, registered in the name of the Trust and having an
aggregate principal amount equal to the aggregate Liquidation Amount of the
Preferred Securities and Common Securities issued and sold on such date, and, in
satisfaction of the purchase price for such Debentures, the Property Trustee, on
behalf of the Trust, shall deliver to the Debenture Issuer the amount received
on such date from one of the Administrative Trustees pursuant to the last
sentence of Section 2.4.

               (J) the taking of any action incidental to the foregoing as the

                                       13
<PAGE>

               (H) to the extent provided in this Trust Agreement, the winding
          up of the affairs of and liquidation of the Trust and the preparation,

     (b) So long as this Trust Agreement remains in effect, the Trust (or the

     appropriate form in relation to the Preferred Securities, including any
     amendments thereto;

          (ii) the determination of the States in which to take appropriate
     action to qualify or register for sale all or part of the Preferred

     the Trustees of actions they must take on behalf of the Trust, and the
     preparation


                                       14
<PAGE>

     for execution and filing of any documents to be executed and filed by the
     Trust or on behalf of the Trust, as the Depositor deems necessary or
     advisable in order to comply with the applicable laws of any such States;

          (iii) the preparation for filing by the Trust and execution on behalf

          (iv) the preparation for filing by the Trust with the Commission and
     the execution on behalf of the Trust of a registration statement on Form
     8-A relating to the registration of the Preferred Securities under Section

          (v) the negotiation of the terms of, and the execution and delivery
     of, the Underwriting Agreement providing for the sale of the Preferred
     Securities; and

          (vi) the taking of any other actions deemed by the Depositor to be
     necessary or desirable to carry out any of the foregoing activities.

     (d) Notwithstanding anything herein to the contrary, the Administrative
Trustees are authorized and directed to conduct the affairs of the Trust and to
operate the Trust so that the Trust will not be deemed to be an "investment
company" required to be registered under the Investment Company Act or
classified as an association taxable as a corporation for United States Federal
income tax purposes and so that the Debentures will be treated as indebtedness
of the Debenture Issuer for United States Federal income tax purposes. In this
connection, the Depositor and the Administrative Trustees are authorized to take
any action, not inconsistent with applicable law, the Certificate of Trust or
this Trust Agreement, that each of the Depositor and the Administrative Trustees
determines in their discretion to be necessary or desirable for such purposes,
as long as such action does not adversely affect in any material respect the
interests of the Holders of the Preferred Securities.

     The assets of the Trust shall consist of the Trust Property.

     Section 2.9 TITLE TO TRUST PROPERTY.

                                 PAYMENT ACCOUNT

     Section 3.1 PAYMENT ACCOUNT.

     (a) On or prior to the Closing Date, the Property Trustee shall establish
the Payment Account. The Property Trustee and any agent of the Property Trustee
shall have exclusive control and sole right of withdrawal with respect to the
Payment Account for the purpose of making deposits in and withdrawals from the
Payment Account in accordance with this Trust Agreement. All monies and other
property deposited or held from time to time in the Payment Account shall be
held by the Property Trustee in the Payment Account for the exclusive benefit of
the Securityholders and for distribution as herein provided, including (and
subject to) any priority of payments provided for herein.

     (b) The Property Trustee shall deposit in the Payment Account, promptly
upon receipt, all payments of principal of or interest on, and any other
payments or proceeds with respect to, the Debentures. Amounts held in the
Payment Account shall not be invested by the Property Trustee pending
distribution thereof.

                                  ARTICLE IV.

                      CERTAIN TERMS OF THE TRUST SECURITIES

     Section 4.1 DISTRIBUTIONS.

     (a) Distributions on the Trust Securities shall be cumulative, and will
accumulate whether or not there are funds of the Trust available for the payment
of Distributions. Distributions shall accrue from __________, ____, and shall be
payable quarterly in arrears on _________, _______, ______ and ________ of each
year, commencing on __________, _____, except as otherwise described below. The
Debenture Issuer has the right under the Indenture, at any time and from time to
time, to defer payments of interest for such period or periods as may be
specified with respect to the Debentures (each, an "Extension Period"), on the
terms and conditions specified in the Indenture. As a consequence of such
deferral, Distributions will also be deferred. Despite such deferral, quarterly
Distributions will continue to accumulate at the rate set forth in paragraph (b)
of this Section 4.1, together with additional distributions thereon (to the
extent permitted by applicable law) at the rate at which Additional Interest is
then accruing on the Debentures, compounded quarterly during any such Extension
Period. If any date on which a Distribution is otherwise payable on the Trust
Securities is not a Business Day, then the payment of such Distribution shall be
made on the next succeeding day that is a Business Day (and without any
additional distributions or other payment in respect of any such delay), except
that, if such Business Day is in the next succeeding calendar year, payment of
such Distribution shall be made on the immediately preceding Business Day, in
each case with the same force and effect as if made on the date such payment was
originally payable (each date on which distributions are payable in accordance
with this Section 4.1(a), a "Distribution Date").



                                       16
<PAGE>

     (b) The Trust Securities represent undivided beneficial interests in the
Trust Property, and, as a practical matter, the Distributions on the Trust
Securities shall be payable at a rate of __% per annum of the Liquidation Amount
of the Trust Securities. The term "Distributions" as used herein includes such
cash distributions and any accumulated or additional distributions that are
payable hereunder unless otherwise stated. The amount of Distributions payable
for any full or partial period shall be computed on the basis of a 360-day year
of twelve 30-day months. The amount of Distributions payable for any period
shall include Additional Amounts, if any.

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

     (d) Distributions on the Trust Securities with respect to a Distribution
Date shall be payable to the Holders thereof as they appear on the Securities
Register at the close of business on the relevant record date, which, as long as
the Preferred Securities remain in book-entry only form, shall be the date one
Business Day immediately preceding such Distribution Date. The relevant record
dates for the Common Securities shall be the same record dates as for the
Preferred Securities. If the Preferred Securities shall not continue to remain
in book-entry only form or are not in book-entry only form at issuance, the
relevant record dates for the Preferred Securities shall be the date 15 days
prior to the relevant Distribution Date, which Distribution Dates shall
correspond to the interest payment dates on the Debentures. Distributions
payable on any Trust Securities that are not punctually paid on any Distribution
Date, as a result of the Debenture Issuer (or the Debenture Guarantor on its
behalf) having failed to make an interest payment under the 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 for determining
Debentureholders entitled to such defaulted interest established in accordance
with the Indenture.

     (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 among the Holders of the Trust Securities. A reference
herein 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, a Debenture Event of Default 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.

     Section 4.2 REDEMPTION.

     (a) On each Debenture Redemption Date and on the stated maturity of the
Debentures, the Trust will be required to redeem a Like Amount of Trust
Securities at a price per Trust Security equal to the Redemption Price.

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

          (i) the Redemption Date;

          (ii) the Redemption Price;

          (iii) the CUSIP number;

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

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

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

     (d) If the Property Trustee gives a notice of redemption (which notice
shall be irrevocable) in respect of any Preferred Securities, then, by 12:00
noon, New York City time, on the Redemption Date, subject to Section 4.2(c), the
Property Trustee will, so long as the Preferred Securities are in
book-entry-only form, irrevocably deposit with the Clearing Agency for the
Preferred Securities funds sufficient to pay the applicable Redemption Price and
will give such Clearing Agency irrevocable instructions and authority to pay the
Redemption Price to the relevant Persons' accounts at such Clearing Agency on
the applicable Redemption Date. If the Preferred Securities are no longer in
book-entry-only form, and in the case of the Common Securities, the Property
Trustee, subject to Section 4.2(c), will irrevocably deposit with the Paying
Agent funds sufficient to pay the applicable Redemption Price and will give the
Paying Agent irrevocable instructions and authority to pay the Redemption Price
to the Holders thereof upon surrender of their Trust Securities Certificates.
Notwithstanding the foregoing, Distributions payable on or prior to the
Redemption Date for any Trust Securities called for redemption shall be payable
to the Holders of such Trust Securities as they appear on the Securities
Register for the Trust Securities


                                       18
<PAGE>

on the relevant record dates for the related Distribution Dates. If notice of
redemption shall have been given and funds deposited as required, then
immediately prior to the close of business on the date of such deposit, all
rights of Securityholders holding Trust Securities so called for redemption will
cease, except the right of such Securityholders to receive the Redemption Price
and any Distributions payable on or prior to the Redemption Date, but without
interest, and such Securities will cease to be outstanding. In the event that
any date on which any Redemption Price is payable is not a Business Day, then
payment of the Redemption Price payable on such date will be made on the next
succeeding day that is a Business Day (and without any interest or other payment
in respect of any such delay), except that, if such Business Day falls in the
next calendar year, such payment will be made on the immediately preceding
Business Day, in each case, with the same force and effect as if made on such
date. In the event that payment of the Redemption Price in respect of any Trust
Securities called for redemption is improperly withheld or refused and not paid
either by the Trust or by the Preferred Securities Guarantor pursuant to the
Guarantee, Distributions on such Trust Securities will continue to accrue, at
the then applicable rate, from the Redemption Date originally established by the
Trust for such Trust Securities to the date such Redemption Price is actually
paid, in which case the actual payment date will be the date fixed for
redemption for purposes of calculating the Redemption Price.

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

     (f) Subject to Section 4.3(a), if less than all the Outstanding Trust
Securities are to be redeemed on a Redemption Date, then the aggregate
Liquidation Amount of Trust Securities to be redeemed shall be allocated on a
pro rata basis (based on Liquidation Amounts) among the Common Securities and
the Preferred Securities. The particular Preferred Securities to be redeemed
shall be selected on a pro rata basis (based upon Liquidation Amounts) not more
than 60 days prior to the Redemption Date by the Property Trustee from the
Outstanding Preferred Securities not previously called for redemption, by such
method (including, without limitation, by lot) as the Property Trustee shall
deem fair and appropriate and which may provide for the selection for redemption
of portions (equal to $____ or an integral multiple of $____ in excess thereof)
of the Liquidation Amount of Preferred Securities of a denomination larger than
$____. The Property Trustee shall promptly notify the Security Registrar in
writing of the Preferred Securities selected for redemption and, in the case of
any Preferred Securities selected for partial redemption, the Liquidation Amount
thereof to be redeemed. For all purposes of this Trust Agreement, unless the
context otherwise requires, all provisions relating to the redemption of
Preferred Securities shall relate, in the case of any Preferred Securities
redeemed or to be redeemed only in part, to the portion of the Liquidation
Amount of Preferred Securities that has been or is to be redeemed.

     Section 4.3 SUBORDINATION OF COMMON SECURITIES.

     (a) Payment of Distributions (including Additional Amounts, if applicable)
on, and the Redemption Price of, the Trust Securities, as applicable, shall be
made, subject to Section 4.2(f), pro rata among the Common Securities and the
Preferred Securities based on the Liquidation Amount of the Trust Securities;
provided, however, that if on any Distribution Date or Redemption Date any Event
of Default resulting from a Debenture Event of Default shall have occurred and
be continuing, no payment of any Distribution (including Additional Amounts, if
applicable) on, or Redemption Price of, any Common Security, and no other
payment on account of the redemption, liquidation or other acquisition of Common
Securities, shall be made unless payment in full in cash of all accumulated and
unpaid Distributions (including Additional Amounts, if applicable) on all
Outstanding Preferred Securities for all Distribution periods terminating on or
prior thereto, or in the case of payment of the Redemption Price the full amount
of such Redemption Price on all Outstanding Preferred Securities, shall have
been made or provided for, and all funds immediately available to the Property
Trustee shall first be applied to the payment in full in cash of all
Distributions (including Additional Amounts, if applicable) on, or the
Redemption Price of, Preferred Securities then due and payable.

     (b) In the case of the occurrence of any Event of Default resulting from
any Debenture Event of Default, the Holder of Common Securities will be deemed
to have waived any right to act with respect to any such Event of Default under
this Trust Agreement until the effect of all such Events of Default with respect
to the Preferred Securities have been cured, waived or otherwise eliminated.
Until any such Event of Default under this Trust Agreement with respect to the
Preferred Securities has 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.

     Section 4.4 PAYMENT PROCEDURES.

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

     Section 4.5 TAX RETURNS AND REPORTS.

     The Administrative Trustees shall prepare (or cause to be prepared), at the
Depositor's expense, and file all United States Federal, state and local tax and

                                       20
<PAGE>

     (a) prepare and file (or cause to be prepared and filed) the appropriate
Internal Revenue Service Form required to be filed in respect of the Trust in
each taxable year of the Trust and

     (b) prepare and furnish (or cause to be prepared and furnished) to each
Securityholder the appropriate Internal Revenue Service form required to be
provided on such form. The Administrative Trustees shall provide the Depositor
and the Property Trustee with a copy of all such returns and reports promptly
after such filing or furnishing. The Trustees shall comply with United States
Federal withholding and backup withholding tax laws and information reporting
requirements with respect to any payments to Securityholders under the Trust
Securities.

     Section 4.6 PAYMENT OF TAXES, DUTIES, ETC. OF THE TRUST.

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

     Section 4.7 PAYMENTS UNDER INDENTURE.

     Any amount payable hereunder to any Holder of Preferred Securities shall be
reduced by the amount of any corresponding payment such Holder (and any Owner
with respect thereto) has directly received pursuant to Section 5.8 of the

                         TRUST SECURITIES CERTIFICATES

     Section 5.1 INITIAL OWNERSHIP.

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

     Section 5.2 THE TRUST SECURITIES CERTIFICATES.

     The Preferred Securities Certificates shall be issued in minimum
denominations of $____ Liquidation Amount and integral multiples of $____ in
excess thereof, and the Common Securities Certificates shall be issued in
denominations of $____ Liquidation Amount and integral multiples of $____ in
excess thereof. The Trust Securities Certificates shall be executed on behalf of
the Trust by manual signature of at least one Administrative Trustee. Trust
Securities Certificates bearing the manual signatures of individuals who were,
at the time when such signatures shall have been affixed, authorized to sign on
behalf of the Trust, shall be validly issued and entitled to the benefits of
this Trust Agreement, notwithstanding that such individuals or any of them shall
have ceased to be so authorized prior to the delivery of such Trust Securities
Certificates or did not hold such offices at the date of delivery of such Trust
Securities Certificates. A transferee of a Trust Securities Certificate shall
become a Securityholder, and shall be entitled to the rights and subject


                                       21
<PAGE>

to the obligations of a Securityholder hereunder, upon due registration of such
Trust Securities Certificate in such transferee's name pursuant to Sections 5.4,
5.11 and 5.13.

     Section 5.3 EXECUTION AND DELIVERY OF TRUST SECURITIES CERTIFICATES.

     At each Time of Delivery, the Administrative Trustees shall cause Trust
Securities Certificates, in an aggregate Liquidation Amount as provided in
Sections 2.4 and 2.5, to be executed on behalf of the Trust and delivered to or
upon the written order of the Depositor, signed by its Chairman of the Board, a
Vice Chairman, its President, a Vice President or its Treasurer and attested by
its Secretary or one of its Assistant Secretaries, without further corporate
action by the Depositor, in authorized denominations.

     Section 5.4 REGISTRATION OF TRANSFER AND EXCHANGE OF PREFERRED SECURITIES
CERTIFICATES.

     The Depositor shall keep or cause to be kept, at the office or agency
maintained pursuant to Section 5.8, a register or registers for the purpose of
registering Trust Securities Certificates and transfers and exchanges of
Preferred Securities Certificates (the "Securities Register"). The registrar
designated by the Depositor (the "Securities Registrar"), subject to such
reasonable regulations as it may prescribe, shall provide for the registration
of Preferred Securities Certificates and Common Securities Certificates (subject
to Section 5.10 in the case of the Common Securities Certificates) and
registration of transfers and exchanges of Preferred Securities Certificates as
herein provided. The Bank shall be the initial Securities Registrar. Upon
surrender for registration of transfer of any Preferred Securities Certificate
at the office or agency maintained pursuant to Section 5.8, the Administrative
Trustees or any one of them shall execute and deliver, in the name of the
designated transferee or transferees, one or more new Preferred Securities
Certificates in authorized denominations of a like aggregate Liquidation Amount
dated the date of execution by such Administrative Trustee or Trustees. The
Securities Registrar shall not be required to register the transfer of any
Preferred Securities after such Preferred Securities have been called for
redemption. At the option of a Holder, Preferred Securities Certificates may be
exchanged for other Preferred Securities Certificates in authorized
denominations of the same class and of a like aggregate Liquidation Amount upon
surrender of the Preferred Securities Certificates to be exchanged at the office
or agency maintained pursuant to Section 5.8. Every Preferred Securities
Certificate presented or surrendered for registration of transfer or exchange
shall be accompanied by a written instrument of transfer in form satisfactory to
an Administrative Trustee and the Securities Registrar duly executed by the
Holder or his attorney duly authorized in writing. Each Preferred Securities
Certificate surrendered for registration of transfer or exchange shall be
cancelled and subsequently disposed of by an Administrative Trustee in
accordance with customary practice. Registration of transfers or exchanges of
Preferred Securities Certificates shall be effected without service charge by or
on behalf of the Trust, but the Securities Registrar may require payment of a
sum sufficient to cover any tax or other governmental charge that may be imposed
in connection with any such transfer or exchange.

     Section 5.5 MUTILATED, DESTROYED, LOST OR STOLEN TRUST SECURITIES
CERTIFICATES.

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

     Section 5.6 PERSONS DEEMED SECURITYHOLDERS.

     Prior to due presentation of a Trust Securities Certificate for
registration of transfer, the Administrative Trustees or the Securities
Registrar shall treat the Person in whose name any Trust Securities Certificate
shall be registered in the Securities Register as the owner of such Trust
Securities Certificate for the purpose of receiving distributions and for all
other purposes whatsoever, and neither the Trustees nor the Securities Registrar
shall be bound by any notice to the contrary.

     Section 5.7 ACCESS TO LIST OF SECURITYHOLDERS' NAMES AND ADDRESSES.

     The Administrative Trustees shall furnish or cause to be furnished (x) to
the Depositor, within 15 days after receipt by any Administrative Trustee of a
request therefor from the Depositor in writing and (y) to the Property Trustee,
promptly after receipt by any Administrative Trustee of a request therefor from
the Property Trustee in writing in order to enable the Property Trustee to
discharge its obligations under this Trust Agreement, a list, in such form as
the Depositor or the Property Trustee may reasonably require, of the names and
addresses of the Securityholders as of a recent date. If Holders of Trust
Securities Certificates evidencing ownership at such time and for the previous
six months of not less than 25% of the Outstanding aggregate Liquidation Amount
apply in writing to any Administrative Trustee, and such application states that
the applicants desire to communicate with other Securityholders with respect to
their rights under this Trust Agreement or under the Trust Securities
Certificates and such application is accompanied by a copy of the communication
that such applicants propose to transmit, then the Administrative Trustees
shall, within five Business Days after the receipt of such application, afford
such applicants access during normal business hours to the current list of
Securityholders. Each Holder, by receiving and holding a Trust Securities
Certificate, and each Owner shall be deemed to have agreed not to hold the


                                       23
<PAGE>

Depositor, the Property Trustee or the Administrative Trustees accountable by
reason of the disclosure of its name and address, regardless of the source from
which such information was derived.

     Section 5.8 MAINTENANCE OF OFFICE OR AGENCY.

     The Administrative Trustees shall maintain in Chicago, Illinois, an office
or offices or agency or agencies where Preferred Securities Certificates may be
surrendered for registration of transfer or exchange and where notices and
demands to or upon the Trustees in respect of the Trust Securities and the Trust
Agreement may be served. The Administrative Trustees initially designate The
First National Bank of Chicago, One First National Plaza, Suite 0126, Chicago,
Illinois 60670-0126; Attention: Corporate Trust Department, as the principal
corporate trust office for such purposes. The Administrative Trustees shall give
prompt written notice to the Depositor and to the Securityholders of any change
in the location of the Securities Register or any such office or agency.

     Section 5.9 APPOINTMENT OF PAYING AGENT.

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

     Section 5.10 OWNERSHIP OF COMMON SECURITIES BY DEPOSITOR.

     At each Time of Delivery, the Depositor shall acquire and retain beneficial
and record ownership of all of the Common Securities then issued by the Trust,
in an amount equal to at least 3% of the total capital of the Trust, at the same
time as the Preferred Securities are issued and sold. The aggregate Liquidation
Amount of the Common Securities at any time shall not be less than 3% of the
total capital of the Trust. To the fullest extent permitted by law, other than a
transfer in connection with a consolidation or merger of the Depositor into
another corporation, or any conveyance, transfer or lease by the Depositor of
its properties and assets substantially as an entirety to any Person, pursuant
to Section 8.1 of the Indenture, any attempted transfer of the Common Securities
shall be void. The Administrative Trustees shall cause each Common Securities
Certificate issued to the Depositor to contain a legend stating "THIS
CERTIFICATE IS NOT TRANSFERABLE EXCEPT AS PROVIDED IN THE TRUST AGREEMENT (AS
DEFINED BELOW)".

     Section 5.11 BOOK-ENTRY PREFERRED SECURITIES CERTIFICATES; COMMON
SECURITIES CERTIFICATE.

     (a) The Preferred Securities Certificates, upon original issuance, will be
issued in the form of a typewritten Preferred Securities Certificate or
Certificates representing Book-Entry Preferred Securities Certificates, to be
delivered to DTC, the initial Clearing Agency, by, or on behalf of, the Trust.
Such Preferred Securities Certificate or Certificates shall initially be
registered on the Securities Register in the name of Cede & Co., the nominee of
the initial Clearing Agency, and no beneficial owner will receive a Definitive
Preferred Securities Certificate representing such beneficial owner's interest
in such Preferred Securities, except as provided in Section 5.13. Except for
Definitive Preferred Securities Certificates as specified herein, unless and
until Definitive Preferred Securities Certificates have been issued to
beneficial owners pursuant to Section 5.13:

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

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

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

          (iv) the rights of the Owners of the Book-Entry Preferred Securities
     Certificates shall be exercised only through the Clearing Agency and shall
     be limited to those established by law and agreements between such Owners
     and the Clearing Agency and/or the Clearing Agency Participants; provided,
     that solely for the purposes of determining whether the Holders of the
     requisite amount of Preferred Securities have voted on any


                                       25
<PAGE>

     matter provided for in this Trust Agreement, so long as Definitive
     Preferred Security Certificates have not been issued, the Trustees may
     conclusively rely on, and shall be protected in relying on, any written
     instrument (including a proxy) delivered to the Trustees by the Clearing
     Agency setting forth the Owners' votes or assigning the right to vote on
     any matter to any other Persons either in whole or in part. Pursuant to the
     Certificate Depository Agreement, unless and until Definitive Preferred
     Securities Certificates are issued pursuant to Section 5.13, the initial
     Clearing Agency will make book-entry transfers among the Clearing Agency
     Participants and receive and transmit payments on the Preferred Securities
     to such Clearing Agency Participants.

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

     Section 5.12 NOTICES TO CLEARING AGENCY.

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

     Section 5.13 DEFINITIVE PREFERRED SECURITIES CERTIFICATES.

     If (a) the Depositor advises the Trustees in writing that the Clearing
Agency is no longer willing or able to act as clearing agency with respect to
the Preferred Securities Certificates, and the Depositor fails to appoint a
qualified successor within 90 days, (b) the Depositor at its option advises the
Trustees in writing that it elects to terminate the book-entry system through
the Clearing Agency or (c) after the occurrence of a Debenture Event of Default,
Owners of Preferred Securities Certificates representing beneficial interests
aggregating at least a majority of the Liquidation Amount of the Outstanding
Preferred Securities advise the Property Trustee in writing that the
continuation of a book-entry system through the Clearing Agency is no longer in
the best interest of the Owners of Preferred Securities Certificates, then the
Property Trustee shall notify the Clearing Agency and the Clearing Agency shall
notify all Owners of Preferred Securities Certificates and the other Trustees of
the occurrence of any such event and of the availability of the Definitive
Preferred Securities Certificates to Owners of such class or classes, as
applicable, requesting the same. Upon surrender to the Property Trustee of the
typewritten Preferred Securities Certificate or Certificates representing the
Book Entry Preferred Securities Certificates by the Clearing Agency, accompanied
by registration instructions, the Administrative Trustees, or any one of them,
shall execute the Definitive Preferred Securities Certificates in accordance
with the instructions of the Clearing Agency. Neither the Securities Registrar
nor the Trustees shall be liable for any delay in delivery of such instructions
and may conclusively rely on, and shall be protected in relying on, such
instructions. Upon the issuance of Definitive Preferred Securities Certificates,
the Trustees shall recognize the Holders of the Definitive Preferred Securities
Certificates as Securityholders. The Definitive Preferred Securities
Certificates shall be printed, lithographed or engraved or may be produced in
any other manner as is reasonably acceptable to


                                       26
<PAGE>

the Administrative Trustees, as evidenced by the execution thereof by the
Administrative Trustees or any one of them.

     Section 5.14 RIGHTS OF SECURITYHOLDERS.

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

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

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

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

               (A) all overdue installments of interest (including any
          Additional Interest) on, and any other Additional Amounts with respect
          to, all of the Debentures,

               (B) the principal of and premium on any Debentures which have
          become due otherwise than by such declaration of acceleration and
          interest thereon and any Additional Amounts with respect thereto at
          the rate or rates borne by or provided for in the Debentures,



                                       27
<PAGE>

               (C) to the extent the payment of such interest or Additional
          Amounts is lawful, interest upon overdue installments of any interest
          and Additional Amounts at the rate or rates borne by or provided for
          in the Debentures, and

               (D) all sums paid or advanced by the Debenture Trustee under the
          Indenture and the reasonable compensation, expenses, disbursements and
          advances of the Debenture Trustee, its agents and counsel and all
          other amounts due the Debenture Trustee under the Indenture; and

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

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

     The Holders of not less than a majority in Liquidation Amount of the
Preferred Securities then Outstanding may, on behalf of the Holders of all the
Preferred Securities, waive any past default under the Indenture, except a
default (i) in the payment of principal of, any premium or interest (including
any Additional Interest) on, or any other Additional Amounts with respect to,
the Debentures or (ii) in respect of a covenant or provision which under the
Indenture cannot be modified or amended without the consent of the holder of
each outstanding Debenture.

     Upon receipt by the Property Trustee of written notice declaring such an
acceleration, or rescission and annulment thereof, by Holders of the Preferred
Securities all or part of which are represented by Book-Entry Preferred
Securities Certificates, a record date shall be established for determining
Holders of Outstanding Preferred Securities entitled to join in such notice,
which record date shall be at the close of business on the day the Property
Trustee receives such notice. The Holders on such record date, or their duly
designated proxies, and only such Persons, shall be entitled to join in such
notice, whether or not such Holders remain Holders after such record date;
provided, that, unless such declaration of acceleration, or rescission and
annulment, as the case may be, shall have become effective by virtue of the
requisite percentage having joined in such notice prior to the day which is 90
days after such record date, such notice of declaration of acceleration, or
rescission and annulment, as the case may be, shall automatically and without
further action by any Holder be canceled and of no further effect. Nothing in
this paragraph shall prevent a Holder, or a proxy of a Holder, from giving,
after expiration of such 90-day period, a new written notice of declaration of
acceleration, or rescission and annulment thereof, as the case may be, that is
identical to a written notice which has been canceled pursuant to the proviso to
the preceding sentence, in which event a new record date shall be established
pursuant to the provisions of this Section 5.14(b).

     (c) For so long as any Preferred Securities remain Outstanding, to the
fullest extent permitted by law and subject to the terms of this Trust Agreement
and the Indenture, any Holder of Preferred Securities shall have the right, upon
a Debenture Event of Default specified in Section


                                       28
<PAGE>

5.1(1) or 5.1(2) of the Indenture, to institute directly a proceeding against
the Debenture Issuer or the Debenture Guarantor, as the case may be, pursuant to
Section 5.8 of the Indenture, for enforcement of payment to such Holder of the
principal of, and any premium and (subject to the provisions of the Indenture)
interest (including any Additional Interest) on, and any other Additional
Amounts with respect to, such Debentures having a principal amount equal to the
Liquidation Amount of the Preferred Securities of such Holder (a "Direct
Action"). In connection with any such Direct Action, the rights of the Holders
of Common Securities will be subrogated to the rights of any Holder of Preferred
Securities to the extent of any payment made by the Debenture Issuer or the
Debenture Guarantor, as the case may be, to such Holder of Preferred Securities
as a result of such Direct Action. Except as set forth in Section 5.14(b) and
(c), or as otherwise contemplated by the Indenture, the Holders of Preferred
Securities shall have no right to exercise directly any right or remedy
available to the holders of, or in respect of, the Debentures.

     Section 6.1 LIMITATIONS ON VOTING RIGHTS.

     (a) Except as provided in this Section, in Sections 5.14, 8.10 and 10.2 and
in the Indenture and as otherwise required by law, no Holder of Preferred
Securities shall have any right to vote or in any manner otherwise control the
administration, operation and management of the Trust or the obligations of the
parties hereto, nor shall anything herein set forth, or contained in the terms
of the Trust Securities Certificates, be construed so as to constitute the
Securityholders from time to time as partners or members of an association.

     (b) So long as any Debentures are held by the Property Trustee, the
Trustees shall not

          (i) direct the time, method and place of conducting any proceeding for
     any remedy available to the Debenture Trustee, or executing any trust or
     power conferred on the Debenture Trustee with respect to such Debentures,

          (ii) waive any past default which is waivable under Section 5.13 of
     the Indenture,

          (iii) exercise any right to rescind or annul a declaration that the
     principal of all the Debentures shall be due and payable, or

          (iv) consent to any amendment, modification or termination of the
     Indenture or the Debentures, where such consent shall be required,

without, in each case, obtaining the prior approval of the Holders of at least a
majority in Liquidation Amount of all Outstanding Preferred Securities;
provided, however, that where a consent under the Indenture would require the
consent of each holder of Debentures affected thereby, no such consent shall be
given by the Property Trustee without the prior written consent of


                                       29
<PAGE>

each Holder of Preferred Securities. The Trustees shall not revoke any action
previously authorized or approved by a vote of the Holders of Preferred
Securities, except by a subsequent vote of the Holders of Preferred Securities.
The Property Trustee shall notify all Holders of the Preferred Securities of any
notice of default received from the Debenture Trustee with respect to the
Debentures. In addition to obtaining the foregoing approvals of the Holders of
the Preferred Securities, prior to taking any of the foregoing actions, the
Trustees shall, at the expense of the Depositor, obtain an Opinion of Counsel
rendered by counsel experienced in such matters to the effect that the Trust
will not be classified as an association taxable as a corporation for United
States Federal income tax purposes on account of such action.

     (c) If any proposed amendment to the Trust Agreement provides for, or the
Trustees otherwise propose to effect,

          (i) any action that would adversely affect in any material respect the
     powers, preferences or special rights of the Preferred Securities, whether
     by way of amendment to the Trust Agreement or otherwise, or

          (ii) the dissolution, winding-up or termination of the Trust, other
     than pursuant to the terms of this Trust Agreement, then the Holders of
     Outstanding Preferred Securities as a class will be entitled to vote on
     such amendment or proposal and such amendment or proposal shall not be
     effective except with the approval of the Holders of at least a majority in
     Liquidation Amount of the Outstanding Preferred Securities. No amendment to
     this Trust Agreement may be made if, as a result of such amendment, the
     Trust would be classified as an association taxable as a corporation for
     United States federal income tax purposes.

     Section 6.2 NOTICE OF MEETINGS.

     Notice of all meetings of the Preferred Securityholders, stating the time,
place and purpose of the meeting, shall be given by the Property Trustee

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

     Section 6.6 SECURITYHOLDER ACTION BY WRITTEN CONSENT.

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

     Section 6.7 RECORD DATE FOR VOTING AND OTHER PURPOSES.

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


                                       31
<PAGE>

distribution or other action, as the case may be, as a record date for the
determination of the identity of the Securityholders of record for such
purposes.

     Section 6.8 ACTS OF SECURITYHOLDERS.

     Any request, demand, authorization, direction, notice, consent, waiver or
other action provided or permitted by this Trust Agreement to be given, made or
taken by Securityholders or Owners may be embodied in and evidenced by one or
more instruments of substantially similar tenor signed by such Securityholders
or Owners in person or by an agent duly appointed in writing; and, except as
otherwise expressly provided herein, such action shall become effective when
such instrument or instruments are delivered to an Administrative Trustee. Such
instrument or instruments (and the action embodied therein and evidenced
thereby) are herein sometimes referred to as the "Act" of the Securityholders or
Owners signing such instrument or instruments. Proof of execution of any such
instrument or of a writing appointing any such agent shall be sufficient for any
purpose of this Trust Agreement and (subject to Section 8.1) conclusive in favor
of the Trustees, if made in the manner provided in this Section. The fact and
date of the execution by any Person of any such instrument or writing may be
proved by the affidavit of a witness of such execution or by a certificate of a
notary public or other officer authorized by law to take acknowledgments of
deeds, certifying that the individual signing such instrument or writing
acknowledged to him the execution thereof. Where such execution is by a signer
acting in a capacity other than his individual capacity, such certificate or
affidavit shall also constitute sufficient proof of his authority. The fact and
date of the execution of any such instrument or writing, or the authority of the
Person executing the same, may also be proved in any other manner which any
Trustee receiving the same deems sufficient. The ownership of Preferred
Securities shall be proved by the Securities Register. Any request, demand,
authorization, direction, notice, consent, waiver or other Act of the
Securityholder of any Trust Security shall bind every future Securityholder of
the same Trust Security and the Securityholder of every Trust Security issued
upon the registration of transfer thereof or in exchange therefor or in lieu
thereof in respect of anything done, omitted or suffered to be done by the
Trustees or the Trust in reliance thereon, whether or not notation of such
action is made upon such Trust Security. Without limiting the foregoing, a
Securityholder entitled hereunder to take any action hereunder with regard to
any particular Trust Security may do so with regard to all or any part of the
Liquidation Amount of such Trust Security or by one or more duly appointed
agents each of which may do so pursuant to such appointment with regard to all
or any part of such Liquidation Amount. If any dispute shall arise between the
Securityholders and the Administrative Trustees or among such Securityholders or
Trustees with respect to the authenticity, validity or binding nature of any
request, demand, authorization, direction, consent, waiver or other Act of such
Securityholder or Trustee under this Article VI, then the determination of such
matter by the Property Trustee shall be conclusive with respect to such matter.

     Section 6.9 INSPECTION OF RECORDS.

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

                                  ARTICLE VII.

                         REPRESENTATIONS AND WARRANTIES

     Section 7.1 REPRESENTATIONS AND WARRANTIES OF THE PROPERTY TRUSTEE AND THE
DELAWARE TRUSTEE.

     The Property Trustee and the Delaware Trustee, each severally on behalf of

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

     Section 7.2 REPRESENTATIONS AND WARRANTIES OF DEPOSITOR

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

     (a) the Trust Securities Certificates issued at each Time of Delivery on
behalf of the Trust have been duly authorized and will have been, duly and
validly executed, issued and delivered by the Trustees pursuant to the terms and

case may be, of this Trust Agreement.

                                  ARTICLE VIII.

                                  THE TRUSTEES

     Section 8.1 CERTAIN DUTIES AND RESPONSIBILITIES.

     (a) The duties and responsibilities of the Trustees shall be as provided by
this Trust Agreement and, in the case of the Property Trustee, subject to the
Trust Indenture Act.


                                       34
<PAGE>

Notwithstanding the foregoing, no provision of this Trust Agreement shall
require the Trustees to expend or risk their own funds or otherwise incur any
financial liability in the performance of any of their duties hereunder, or in
the exercise of any of their rights or powers, if they shall have reasonable
grounds for believing that repayment of such funds or adequate indemnity against
such risk or liability is not reasonably assured to it. Whether or not therein
expressly so provided, every provision of this Trust Agreement relating to the
conduct or affecting the liability of or affording protection to the Trustees
shall be subject to the provisions of this Section. To the extent that, at law
or in equity, an Administrative Trustee has duties (including fiduciary duties)
and liabilities relating thereto to the Trust or to the Securityholders, such
Administrative Trustee shall not be liable to the Trust or to any Securityholder
for such Trustee's good faith reliance on the provisions of this Trust
Agreement. The provisions of this Trust Agreement, to the extent that they
restrict the duties and liabilities of the Administrative Trustees otherwise
existing at law or in equity, are agreed by the Depositor and the
Securityholders to replace such other duties and liabilities of the
Administrative Trustees.

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

     (c) No provision of this Trust Agreement shall be construed to relieve the
Property Trustee from liability for its own bad faith, negligence or willful
misconduct, except that: (i) the Property Trustee undertakes to perform only
those duties specifically set forth in this Agreement, provided that, it must
exercise the same degree of care as a prudent person would exercise in the
conduct of his or her own affairs; (ii) the Property Trustee shall not be liable
for any error of judgment made in good faith by an authorized officer of the
Property Trustee, unless it shall be proved that the Property Trustee was
negligent in ascertaining the pertinent facts; (iii) 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; (iv) the Property Trustee's sole duty with
respect to the custody, safe keeping and physical preservation of the Debentures
and the Payment Account shall be to deal with such Property in a similar manner
as the Property Trustee deals with similar property for its own account, subject
to the protections and limitations on liability afforded to the Property Trustee
under this Trust Agreement and the Trust Indenture Act; (v) the Property Trustee
shall not be liable for any interest on any money received by it except as it
may otherwise agree with the Depositor; and money held by the Property Trustee
need not be segregated from other


                                       35
<PAGE>

funds held by it except in relation to the Payment Account maintained by the
Property Trustee pursuant to Section 3.1 and except to the extent otherwise
required by law; and (vi) the Property Trustee shall not be responsible for
monitoring the compliance by the Administrative Trustees or the Depositor with
their respective duties under this Trust Agreement, nor shall the Property
Trustee be liable for the default or misconduct of the Administrative Trustees
or the Depositor.

     Section 8.2 CERTAIN NOTICES.

     Within five (5) Business Days after the occurrence of any Event of Default
actually known to the Property Trustee, the Property Trustee shall transmit, in
the manner and to the extent provided in Section 10.8, notice of such Event of
Default to the Securityholders, the Administrative Trustees and the Depositor,
unless such Event of Default shall have been cured or waived. Within five
Business Days after the receipt of notice of the Debenture Issuer's exercise of
its right to defer the payment of interest on the Debentures pursuant to the
Indenture, the Administrative Trustees shall transmit, in the manner and to the
extent provided in Section 10.8, notice of such exercise to the Securityholders
and the Property Trustee, unless such exercise shall have been revoked.

     Section 8.3 CERTAIN RIGHTS OF PROPERTY TRUSTEE.

     Subject to the provisions of Section 8.1:

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

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



                                       36
<PAGE>

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

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

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

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

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

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

     (i) the Property Trustee may execute any of the trusts or powers hereunder
or perform any duties hereunder either directly or by or through its agents or
attorneys, provided that the Property Trustee shall be responsible for its own
negligence or recklessness with respect to selection of any agent or attorney
appointed by it hereunder;

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



                                       37
<PAGE>

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

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

     Section 8.4 NOT RESPONSIBLE FOR RECITALS OR ISSUANCE OF SECURITIES.

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

     Section 8.5 MAY HOLD SECURITIES.

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

     Section 8.6 COMPENSATION; INDEMNITY; FEES.

     The Depositor agrees:

     (a) to pay to the Trustees from time to time reasonable compensation for
all services rendered by them hereunder (which compensation shall not be limited
by any provision of law in regard to the compensation of a trustee of an express
trust);

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

     (c) to indemnify each of the Trustees or any predecessor Trustee for, and
to hold the Trustees harmless against, any loss, damage, claims, liability,
penalty or expense incurred without bad faith, negligence or willful misconduct
on its part, arising out of or in connection with the acceptance or
administration of this Trust Agreement, including the costs and expenses of



                                       38
<PAGE>

defending itself against any claim or liability in connection with the exercise
or performance of any of its powers or duties hereunder.

     The provisions of this Section 8.6 shall survive the termination of this
Trust Agreement or the resignation or removal of any Trustee. No Trustee may
claim any lien or charge on any Trust Property as a result of any amount due
pursuant to this Section 8.6.

     Section 8.7 CORPORATE PROPERTY TRUSTEE REQUIRED; ELIGIBILITY OF TRUSTEES.

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

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

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

     Section 8.8 CONFLICTING INTERESTS.

     If the Property Trustee has or shall acquire a conflicting interest within
the meaning of the Trust Indenture Act, the Property Trustee shall either
eliminate such interest or resign, to the extent and in the manner provided by,
and subject to the provisions of, the Trust Indenture Act and this Trust
Agreement. Subject to the foregoing, the Depositor and any Trustee 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 shall have no rights by virtue of this
Trust Agreement in and to such independent ventures or the income or profits
derived therefrom, and the pursuit of any such venture, even if competitive with
the business of the Trust, shall not be deemed wrongful or improper. Neither the
Depositor, nor any Trustee, shall be obligated to present any particular
investment or other opportunity to the Trust even if such opportunity is of a
character that, if presented to the Trust, could be taken by the Trust, and the
Depositor or any Trustee shall have the right to take for its own account
(individually or as a partner or fiduciary) or to recommend to others any such
particular investment or other opportunity.


                                       39
<PAGE>

Any Trustee may engage in any financial or other transaction with the Depositor
or any Affiliate of the Depositor, or may act as depository for, trustee or
agent for, or act on any committee or body of holders of, securities or other
obligations of the Depositor or its Affiliates.

     Section 8.9 CO-TRUSTEES AND SEPARATE TRUSTEE.

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

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

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



                                       40
<PAGE>

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

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

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

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

     Section 8.10 RESIGNATION AND REMOVAL; APPOINTMENT OF SUCCESSOR.

     No resignation or removal of any Trustee (the "Relevant Trustee") and no
appointment of a successor Trustee pursuant to this Article shall become
effective until the acceptance of appointment by the successor Trustee in
accordance with the applicable requirements of Section 8.11. Subject to the
immediately preceding sentence, the Relevant Trustee may resign at any time with
respect to the Trust Securities by giving written notice thereof to the
Depositor. If the instrument of acceptance by the successor Trustee required by
Section 8.11 shall not have been delivered to the Relevant Trustee within 30
days after the giving of such notice of resignation, the Relevant Trustee may
petition, at the expense of the Depositor, any court of competent jurisdiction
for the appointment of a successor Relevant Trustee with respect to the Trust
Securities. Unless a Debenture Event of Default shall have occurred and be
continuing, any Trustee may be removed at any time by Act of the Common
Securityholder. If a Debenture Event of Default shall have occurred and be
continuing, the Property Trustee or the Delaware Trustee, or both of them, may
be removed at such time by Act of the Holders of a majority in Liquidation
Amount of the Preferred Securities, delivered to the Relevant Trustee (in its
individual capacity and on behalf of the Trust). In no event will the Holders of
Preferred Securities have the right to vote to appoint, remove or replace the
Administrative Trustees. An Administrative Trustee may be removed by Act of the
Common Securityholder at any time. If any Trustee shall resign, be removed or
become incapable of acting as Trustee, or if a vacancy shall occur in the office
of any Trustee for any cause, at a time when no Debenture Event of Default shall
have occurred and be continuing, the Common Securityholder, by Act of the Common
Securityholder delivered to the retiring Trustee, shall promptly appoint a
successor Trustee or Trustees with respect to the Trust Securities and the
Trust, and the retiring Trustee shall comply with the applicable requirements of
Section 8.11. If the Property Trustee or the Delaware Trustee shall resign, be
removed or become incapable of


                                       41
<PAGE>

continuing to act as the Property Trustee or the Delaware Trustee, as the case
may be, at a time when a Debenture Event of Default shall have occurred and be
continuing, the Preferred Securityholders, by Act of the Securityholders of a
majority in Liquidation Amount of the Preferred Securities then Outstanding
delivered to the retiring Relevant Trustee, shall promptly appoint a successor
Relevant Trustee or Trustees with respect to the Trust Securities and the Trust,
and such successor Trustee shall comply with the applicable requirements of
Section 8.11. If an Administrative Trustee shall resign, be removed or become
incapable of acting as Administrative Trustee, at a time when a Debenture Event
of Default shall have occurred and be continuing, the Common Securityholder by
Act of the Common Securityholder delivered to the Administrative Trustee shall
promptly appoint a successor Administrative Trustee or Administrative Trustees
with respect to the Trust Securities and the Trust, and such successor
Administrative Trustee or Trustees shall comply with the applicable requirements
of Section 8.11. If no successor Relevant Trustee with respect to the Trust
Securities shall have been so appointed by the Common Securityholder or the
Preferred Securityholders and accepted appointment in the manner required by
Section 8.11, any Securityholder who has been a Securityholder of Trust
Securities for at least six months may, on behalf of himself and all others
similarly situated, petition any court of competent jurisdiction for the
appointment of a successor Relevant Trustee with respect to the Trust
Securities. The Depositor shall give notice of each resignation and each removal
of the Property Trustee or the Delaware Trustee and each appointment of a
successor Property Trustee or Delaware Trustee to all Securityholders in the
manner provided in Section 10.8. Each notice shall include the name of the
successor Relevant Trustee and the address of its Corporate Trust Office if it
is the Property Trustee. Notwithstanding the foregoing or any other provision of
this Trust Agreement, in the event any Administrative Trustee or a Delaware
Trustee who is a natural person dies or becomes, in the opinion of the
Depositor, incompetent or incapacitated, the vacancy created by such death,
incompetence or incapacity may be filled by (a) the unanimous act of remaining
Administrative Trustees if there are at least two of them or (b) otherwise by
the Depositor (with the successor in each case being a Person who satisfies the
eligibility requirement for Administrative Trustees set forth in Section 8.7).

     Section 8.11 ACCEPTANCE OF APPOINTMENT BY SUCCESSOR.

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


                                       42
<PAGE>

deliver an amendment hereto wherein each successor Relevant Trustee shall accept
such appointment and which

     (a) shall contain such provisions as shall be necessary or desirable to
transfer and confirm to, and to vest in, each successor Relevant Trustee all the
rights, powers, trusts and duties of the retiring Relevant Trustee with respect
to the Trust Securities and the Trust and

     (b) shall add to or change any of the provisions of this Trust Agreement as
shall be necessary to provide for or facilitate the administration of the trusts
hereunder by more than one Relevant Trustee, it being understood that nothing
herein or in such amendment shall constitute such Relevant Trustees co-trustees
of the same trust and that each such Relevant Trustee shall be trustee of a
trust or trusts hereunder separate and apart from any trust or trusts hereunder
administered by any other such Relevant Trustee and upon the execution and
delivery of such amendment the resignation or removal of the retiring Relevant
Trustee shall become effective to the extent provided therein and each such
successor Relevant Trustee, without any further act, deed or conveyance, shall
become vested with all the rights, powers, trusts and duties of the retiring
Relevant Trustee with respect to the Trust Securities and the Trust; but, on
request of the Trust or any successor Relevant Trustee such retiring Relevant
Trustee shall duly assign, transfer and deliver to such successor Relevant
Trustee all Trust Property, all proceeds thereof and money held by such retiring
Relevant Trustee hereunder with respect to the Trust Securities and the Trust.
Upon request of any such successor Relevant Trustee, the Trust shall execute any
and all instruments for more fully and certainly vesting in and confirming to
such successor Relevant Trustee all such rights, powers and trusts referred to
in the first or second preceding paragraph, as the case may be. No successor
Relevant Trustee shall accept its appointment unless at the time of such
acceptance such successor Relevant Trustee shall be qualified and eligible under
this Article.

     Section 8.12 MERGER, CONVERSION, CONSOLIDATION OR SUCCESSION TO BUSINESS.

     Any corporation into which the Property Trustee or the Delaware Trustee (or
any Administrative Trustee that is not a natural person) may be merged or
converted or with which it may be consolidated, or any corporation resulting
from any merger, conversion or consolidation to which such Relevant Trustee
shall be a party, shall be the successor of such Relevant Trustee hereunder,
provided such corporation shall be otherwise qualified and eligible under this
Article, without the execution or filing of any paper or any further act on the
part of any of the parties hereto.

     Section 8.13 PREFERENTIAL COLLECTION OF CLAIMS AGAINST DEPOSITOR, DEBENTURE
ISSUER OR TRUST.

     If and when the Property Trustee or the Delaware Trustee shall be or become
a creditor of the Depositor, the Debenture Issuer or the Trust (or any other
obligor upon the Debentures or the Trust Securities), the Property Trustee or
the Delaware Trustee, as the case may be, shall be subject to and shall take all
actions necessary in order to comply with the provisions of the Trust Indenture


                                       43
<PAGE>

Act regarding the collection of claims against the Depositor, Debenture Issuer
or Trust (or any such other obligor).

     Section 8.14 REPORTS BY PROPERTY TRUSTEE.

     (a) Within 60 days after September 15 of each year commencing with the
first September 15 following the first issuance of Preferred Securities pursuant
to this Trust Agreement, the Property Trustee shall transmit to all
Securityholders in accordance with Section 10.8, and to the Depositor, a brief
report dated as of such September 15 with respect to: (i) its eligibility under
Section 8.7 or, in lieu thereof, if to the best of its knowledge it has
continued to be eligible under said Section, a written statement to such effect;
(ii) a statement that the Property Trustee has complied with all of its
obligations under this Trust Agreement during the twelve-month period (or, in
the case of the initial report, the period since the Closing Time) ending with
such September 15 or, if the Property Trustee has not complied in any material
respect with such obligations, a description of such noncompliance; and (iii)
any change in the property and funds in its possession as Property Trustee since
the date of its last report and any action taken by the Property Trustee in the
performance of its duties hereunder which it has not previously reported and
which in its opinion materially affects the Trust Securities.

     (b) In addition the Property Trustee shall transmit to Securityholders such
reports concerning the Property Trustee and its actions under this Trust
Agreement as may be required pursuant to the Trust Indenture Act at the times
and in the manner provided pursuant thereto.

     (c) A copy of each such report shall, at the time of such transmission to
Holders, be filed by the Property Trustee with each stock exchange, interdealer
quotation system or other self-regulatory organization upon which the Trust
Securities are listed or traded, with the Commission and with the Depositor.

     Section 8.15 REPORTS TO THE PROPERTY TRUSTEE.

     The Depositor and the Administrative Trustees on behalf of the Trust shall
provide to the Property Trustee such documents, reports and information as
required by Section 314 of the Trust Indenture Act (if any) and the compliance
certificate required by Section 314(a) of the Trust Indenture Act in the form,
in the manner and at the times required by Section 314 of the Trust Indenture
Act.

     Section 8.16 EVIDENCE OF COMPLIANCE WITH CONDITIONS PRECEDENT.

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

     Section 8.17 NUMBER OF TRUSTEES.

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

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

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

     Section 8.18 DELEGATION OF POWER.

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

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

                                  ARTICLE IX.

                DISSOLUTION, LIQUIDATION, TERMINATION AND MERGER

     Section 9.1 DISSOLUTION UPON EXPIRATION DATE.

     Unless earlier dissolved, the Trust shall automatically dissolve on
December 31, 2054 (the "Expiration Date").

     Section 9.2 EARLY DISSOLUTION.

     The first to occur of any of the following events is an "Early Termination
Event", upon the occurrence of which the Trust shall be dissolved:

     (a) the occurrence of a Bankruptcy Event in respect of, or the dissolution
or liquidation of, the Debenture Issuer or the Debenture Guarantor;

     (b) the written direction to the Property Trustee from the Depositor at any
time (which direction is optional and wholly within the discretion of the
Depositor) to dissolve the Trust and distribute a Like Amount of Debentures to
Securityholders in exchange for the Trust Securities;

     (c) the redemption of all of the Trust Securities in connection with the
redemption of all the Debentures; and

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

     Section 9.3 TERMINATION.

     The respective obligations and responsibilities of the Trustees and the
Trust shall terminate upon the latest to occur of the following:

     (a) the distribution by the Property Trustee to Securityholders upon the
liquidation of the Trust pursuant to Section 9.4, or upon the redemption of all
of the Trust Securities pursuant to Section 4.2, of all amounts required to be
distributed hereunder upon the final payment of the Trust Securities;

     (b) the payment of any expenses owed by the Trust; and

     (c) the discharge of all administrative duties of the Administrative
Trustees, including the performance of any tax reporting obligations with
respect to the Trust or the Securityholders.

     Section 9.4 LIQUIDATION.

     (a) If an Early Termination Event specified in clause (a), (b), or (d) of
Section 9.2 occurs or upon the Expiration Date, the Trust shall be liquidated by
the Trustees as expeditiously as the Trustees determine to be possible by
distributing, after satisfaction of liabilities to creditors of


                                       46
<PAGE>

the Trust as provided by applicable law, to each Securityholder a Like Amount of
Debentures, subject to Section 9.4(e).

     (b) Notice of liquidation shall be given by the Property Trustee by
first-class mail, postage prepaid mailed not later than 30 nor more than 60 days
prior to the Liquidation Date to each Holder of Trust Securities at such
Holder's address appearing in the Securities Register. All notices of
liquidation shall: (i) state the Liquidation Date; (ii) state that from and
after the Liquidation Date, the Trust Securities will no longer be deemed to be
Outstanding and any Trust Securities Certificates not surrendered for exchange
will be deemed to represent a Like Amount of Debentures; and (iii) provide such
information with respect to the mechanics by which Holders may exchange Trust
Securities Certificates for Debentures, or if Section 9.4(e) applies, receive a
Liquidation Distribution, as the Administrative Trustees or the Property Trustee
shall deem appropriate.

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

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

     (e) In the event that, notwithstanding the other provisions of this Section
9.4, whether because of an order for dissolution entered by a court of competent
jurisdiction or otherwise, distribution of the Debentures in the manner provided
herein is determined by the Property Trustee not to be practical, the Trust
Property shall be liquidated, and the Trust shall be wound-up and terminated by
the Property Trustee in such manner as the Property Trustee determines. In such
event, Securityholders will be entitled to receive out of the assets of the
Trust available for distribution to Securityholders, after satisfaction of
liabilities to creditors of the Trust as provided by applicable law, an amount
equal to the Liquidation Amount per Trust Security plus accumulated


                                       47
<PAGE>

and unpaid Distributions thereon to the date of payment (such amount being the
"Liquidation Distribution"). If, upon any such winding up, the Liquidation
Distribution can be paid only in part because the Trust has insufficient assets
available to pay in full the aggregate Liquidation Distribution, then, subject
to the next succeeding sentence, the amounts payable by the Trust on the Trust
Securities shall be paid on a pro rata basis (based upon Liquidation Amounts).
The Holder of the Common Securities will be entitled to receive Liquidation
Distributions upon any such dissolution pro rata (determined as aforesaid) with
Holders of Preferred Securities, except that, if a Debenture Event of Default
has occurred and is continuing, the Preferred Securities shall have a priority
over the Common Securities.

     Section 9.5 MERGERS, CONSOLIDATIONS, AMALGAMATIONS OR REPLACEMENTS OF THE
TRUST.

     The Trust may not merge with or into, convert into, consolidate,
amalgamate, or be replaced by, or convey, transfer or lease its properties and
assets substantially as an entirety to any corporation or other entity, except
pursuant to this Section 9.5 or Section 9.4. The Trust may, at the request of
the Depositor, with the consent of only the Administrative Trustees and without
the consent of the Holders of the Preferred Securities, merge with or into,
convert into, consolidate, amalgamate, or be replaced by or convey, transfer or
lease its properties and assets substantially as an entirety to a trust
organized as such under the laws of any State; provided, that (i) such successor
entity either (a) expressly assumes all of the obligations of the Trust with
respect to the Preferred Securities or (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 rank in priority with respect to
distributions and payments upon liquidation, redemption and otherwise, (ii) the
Depositor expressly appoints a trustee of such successor entity possessing the
same powers and duties as the Property Trustee as the holder of the Debentures,
(iii) the Successor Securities are listed or traded, or any Successor Securities
will be listed upon notification of issuance, on any national securities
exchange or other organization on which the Preferred Securities are then listed
or traded, if any, (iv) such merger, conversion, consolidation, amalgamation,
replacement, conveyance, transfer or lease does not cause the Preferred
Securities (including any Successor Securities) to be downgraded by any
nationally recognized statistical rating organization, (v) such merger,
conversion, consolidation, amalgamation, replacement, conveyance, transfer or
lease does not adversely affect the rights, preferences and privileges of the
Holders of the Preferred Securities (including any Successor Securities) in any
material respect, (vi) such successor entity has a purpose substantially
identical to that of the Trust, (vii) prior to such merger, conversion,
consolidation, amalgamation, replacement, conveyance, transfer or lease, the
Depositor has received an Opinion of Counsel rendered by independent counsel
experienced in such matters to the effect that (a) such merger, conversion,
consolidation, amalgamation, replacement, conveyance, transfer or lease does not
adversely affect the rights, preferences and privileges of the Holders of the
Preferred Securities (including any Successor Securities) in any material
respect, and (b) following such merger, conversion, consolidation, amalgamation,
replacement, conveyance, transfer or lease, neither the Trust nor such successor
entity will be required to register as an investment company under the
Investment Company Act and (viii) the Depositor (or any permitted successor or
assignee) owns all of the


                                       48
<PAGE>

common securities of such successor entity and guarantees the obligations of
such successor entity under the Successor Securities at least to the extent
provided by the Guarantee. Notwithstanding the foregoing, the Trust shall not,
except with the consent of holders of 100% in Liquidation Amount of the
Preferred Securities, consolidate, amalgamate, merge with or into, convert into,
or be replaced by or convey, transfer or lease its properties and assets
substantially as an entirety to any other entity or permit any other entity to
consolidate, amalgamate, merge with or into, convert into, or replace it if such
consolidation, amalgamation, merger, conversion, replacement, conveyance,
transfer or lease would cause the Trust or the successor entity to be classified
as other than a grantor trust for United States Federal income tax purposes.

                                   ARTICLE X.

                            MISCELLANEOUS PROVISIONS

     Section 10.1 LIMITATION OF RIGHTS OF SECURITYHOLDERS.

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

ambiguity, correct or supplement any provision herein which may be inconsistent
with any other provision herein, or to make any other provisions with respect to
matters or questions arising under this Trust Agreement, which shall not be
inconsistent with the other provisions of this Trust Agreement, or (ii) to
modify, eliminate or add to any provisions of this Trust Agreement to such
extent as shall be necessary to ensure that the Trust will be classified for
United States Federal income tax purposes as a grantor trust at all times that
any Trust Securities are outstanding or to ensure that the Trust will not be
required to register as an investment company under the Investment Company;
provided, however, that in the case of clause (i), such action shall not
adversely affect in any material respect the interests of any Securityholder.
Any such amendments of this Trust Agreement shall become effective when notice
thereof is given to the Securityholders.

     (b) Except as provided in Section 10.2(c) hereof, any provision of this
Trust Agreement may be amended by the Trustees and the Depositor with (i) the
consent of Trust Securityholders representing not less than a majority (based
upon Liquidation Amounts) of the Trust Securities then Outstanding and (ii)
receipt by the Trustees of an Opinion of Counsel to the effect that such
amendment or the exercise of any power granted to the Trustees in accordance
with such amendment will not affect the Trust's status as a grantor trust for
United States Federal income tax


                                       49
<PAGE>

purposes or the Trust's exemption from status of an investment company under the
Investment Company Act.

     (c) In addition to and notwithstanding any other provision in this Trust
Agreement, without the consent of each affected Securityholder, this Trust
Agreement may not be amended to (i) change the amount or timing of any
Distribution on the Trust Securities or otherwise adversely affect the amount of
any Distribution required to be made in respect of the Trust Securities as of a
specified date or (ii) restrict the right of a Securityholder to institute suit
for the enforcement of any such payment on or after such date. Notwithstanding
any other provision herein, without the unanimous consent of the
Securityholders, this paragraph (c) of this Section 10.2 may not be amended.

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

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

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

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

     Section 10.3 SEPARABILITY.

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

     Section 10.4 GOVERNING LAW.

Securityholders, the Trust and the Trustees with respect to this Trust Agreement
and the Trust Securities shall be construed in accordance with and governed by

     Section 10.5 PAYMENTS DUE ON NON-BUSINESS DAY.

     If the date fixed for any payment on any Trust Security shall be a day that
is not a Business Day, then such payment need not be made on such date but may
be made on the next succeeding day that is a Business Day (except as otherwise

"Attention Administrative Trustees of ACE Capital Trust III." Such notice,
demand or other communication to or upon the Trust or the Property Trustee shall
be deemed to have been sufficiently given or made only upon actual receipt of
the writing by the Trust or the Property Trustee.

     Section 10.9 AGREEMENT NOT TO PETITION.

     Each of the Trustees and the Depositor agree for the benefit of the
Securityholders that, until at least one year and one day after the Trust has
been dissolved in accordance with Article IX, they shall not file, or join in
the filing of, a petition against the Trust under any bankruptcy, insolvency,
reorganization or other similar law (including, without limitation, the United
States Bankruptcy Code) (collectively, "Bankruptcy Laws") or otherwise join in
the commencement of any proceeding against the Trust under any Bankruptcy Law.
In the event the Depositor takes action in violation of this Section 10.9, the
Property Trustee agrees, for the benefit of Securityholders, that at the expense
of the Depositor, it shall file an answer with the bankruptcy court or otherwise
properly contest the filing of such petition by the Depositor against the Trust
or the commencement of such action and raise the defense that the Depositor has
agreed in writing not to take such action and should be stopped and precluded
therefrom and such other defenses, if any, as counsel for the Trustee or the
Trust may assert. The provisions of this Section 10.9 shall survive the
termination of this Trust Agreement.

     Section 10.10 TRUST INDENTURE ACT; CONFLICT WITH TRUST INDENTURE ACT.

     (a) This Trust Agreement is subject to the provisions of the Trust
Indenture Act that are required to be part of this Trust Agreement and shall, to
the extent applicable, be governed by such provisions.

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

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

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

Attention: John C. Drennan
           General Counsel's Officer

Re: ACE Capital Trust III _____% Trust Originated Preferred Securities

Ladies and Gentlemen:

     The purpose of this letter is to set forth certain matters relating to the
issuance and deposit with The Depository Trust Company ("DTC") of the ACE
Capital Trust III ____% Trust Originated Preferred Securities (the "Preferred
Securities"), of ACE Capital Trust III, a Delaware business trust (the
"Issuer"), governed by an Amended and Restated Trust Agreement among ACE INA
Holdings Inc. ("ACE INA") and The First National Bank of Chicago, as Property
Trustee, Bank One Delaware, Inc., as Delaware Trustee, and the Administrative
Trustees named therein. The payment of distributions on the Preferred
Securities, and payments due upon liquidation of Issuer or redemption of the
Preferred Securities, to the extent the Issuer has funds available for the
payment thereof are guaranteed by ACE Limited, a Cayman Islands company and the
parent of ACE INA ("ACE"), to the extent set forth in a Guarantee Agreement
dated ______________, ____ by ACE with respect to the Preferred Securities. ACE
INA, ACE and the Issuer propose to sell the Preferred Securities to certain
Underwriters (the "Underwriters") pursuant to an Underwriting Agreement dated
__________, 1999 by and among the Underwriters, the Issuer, ACE INA and ACE
dated _____, ____, and the Underwriters wish to take delivery of the Preferred
Securities through DTC. The First National Bank of Chicago is acting as transfer
agent and registrar with respect to the Preferred Securities (the "Transfer
Agent and Registrar").

     To induce DTC to accept the Preferred Securities as eligible for deposit at
DTC, and to act in accordance with DTC's rules with respect to the Preferred
Securities, the Issuer, the Transfer Agent and Registrar and DTC agree among
each other as follows:

     (1) Prior to the closing of the sale of the Preferred Securities to the
Underwrites, which is expected to occur on or about _________________, there
shall be deposited with DTC one or more global certificates (individually and
collectively, the "Global Certificate") registered in the name of DTC's
Preferred Securities nominee, Cede & Co., representing an aggregate of Preferred
Securities and bearing the following legend:

     Unless this certificate is presented by an authorized representative of The
Depository Trust Company, a New York corporation ("DTC"), to the Issuer or its
agent for registration of transfer,


                                      B-1
<PAGE>

exchange, or payment, and any certificate issued is registered in the name of
Cede & Co. or in such other name as is requested by an authorized representative
of DTC (and any payment is made to Cede & Co. or to such other entity as is
requested by an authorized representative of DTC), ANY TRANSFER, PLEDGE, OR
OTHER USE HEREOF FOR VALUE OR OTHERWISE BY OR TO ANY PERSON IS WRONGFUL inasmuch
as the registered owner hereof, Cede & Co., has an interest herein.

     (2) The Amended and Restated Trust Agreement of the Issuer provides for the
voting by holders of the Preferred Securities under certain limited
circumstances. The Issuer shall establish a record date for such purposes and
shall, to the extent possible, give DTC notice of such record date not less than
15 calendar days in advance of such record date.

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

     (4) In the event of distribution on, or an offering or issuance of rights
with respect to, the Preferred Securities outstanding, the Issuer or the
Transfer Agent and Registrar shall send DTC a notice specifying: (a) the amount
of and conditions, if any, applicable to the payment of any such distribution or
any such offering or issuance of rights; (b) any applicable expiration or
deadline date, or any date by which any action on the part of the holders of
Preferred Securities is required; and (c) the date any required notice is to be
mailed by or on behalf of the Issuer to holders of Preferred Securities or
published by or on behalf of the Issuer (whether by mail or publication, the
"Publication Date"). Such notice shall be sent to DTC by a secure means (e.g.,
legible telecopy, registered or certified mail, overnight delivery) in a timely
manner designed to assure that such notice is in DTC's possession no later than
the close of business on the business day before the Publication Date. The
Issuer or the Transfer Agent and Registrar will forward such notice either in a
separate secure transmission for each CUSIP number or in a secure transmission
of multiple CUSIP numbers (if applicable) that includes a manifest or list of
each CUSIP number submitted in that transmission. (The party sending such notice
shall have a method to verify subsequently the use of such means and the
timeliness of such notice.) The Publication Date shall be not less than 30
calendar days nor more than 60 calendar days prior to the payment of any such
distribution or any such offering or issuance of rights with respect to the
Preferred Securities. After establishing the amount of payment to be made on the
Preferred Securities, the Issuer or the Transfer Agent and Registrar will notify
DTC's Dividend Department of such payment 5 business days prior to payment date.
Notices to DTC's Dividend Department by telecopy shall be sent to (212)
709-1723. Such notices by mail or by any other means shall be sent to:

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

not less than 30 calendar days prior to such event by a secure means in the

such notice shall be confirmed by telephoning (516) 227-4070. Notice by mail or

     Call Notification Department
     The Depository Trust Company
     711 Stewart Avenue
     Garden City, New York 11530-4719.

notice specifying the terms of the tender and the Publication Date of such
notice shall be sent by the Issuer or the Transfer Agent and Registrar to DTC by
a secure means and in a timely manner as described in paragraph 4. Notices to
DTC pursuant to this paragraph and notices of other corporate actions (including
mandatory tenders, exchanges and capital changes) shall be sent, unless

          determined solely by the express provisions of this Guarantee

          therein, upon any certificates or opinions furnished to the Guarantee
          Trustee and conforming to the requirements of this Guarantee

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

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

     Trustee to expend or risk its own funds or otherwise incur personal
     financial liability in the performance of any of its duties or in the
     exercise of any of its rights or powers, if the Guarantee Trustee shall
     have reasonable grounds for believing that the repayment of such funds or
     liability is not reasonably assured to it under the terms of this Guarantee
     Agreement or adequate indemnity against such risk or liability is not
     reasonably assured to it.

     costs, expenses (including attorneys' fees and expenses) and liabilities
     that might be incurred by it in complying with such request or direction,
     including such reasonable advances as may be requested by the Guarantee
     Trustee; provided that, nothing contained in this Section 3.2(a)(v) shall
     be taken to relieve the Guarantee Trustee, upon the occurrence of an Event
     of Default, of its obligation to exercise the rights and powers vested in
     it by this Guarantee Agreement.

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

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

          (viii) Any action taken by the Guarantee Trustee or its agents
     hereunder shall bind the Holders, and the signature of the Guarantee
     Trustee or its agents alone shall be sufficient and effective to perform
     any such action. No third party shall be required to inquire as to the
     authority of the Guarantee Trustee to so act or as to its compliance with
     any of the terms and provisions of this Guarantee Agreement, both of which
     shall be conclusively evidenced by the Guarantee Trustee's or its agent's
     taking such action.

          (ix) Whenever in the administration of this Guarantee Agreement the
     Guarantee Trustee shall deem it desirable to receive instructions with
     respect to enforcing any remedy or right or taking any other action
     hereunder, the Guarantee Trustee (A) may request instructions from the
     Holders of a Majority in liquidation preference of the Preferred
     Securities, (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.

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


                                       9
<PAGE>

permissive power or authority available to the Guarantee Trustee shall be
construed to be a duty to act in accordance with such power and authority.

SECTION 3.3 Indemnity

     The Guarantor agrees to indemnify the Guarantee Trustee for, and to hold it
harmless against, any loss, liability or expense incurred without negligence,
bad faith or willful misconduct on the part of the Guarantee Trustee, arising
out of or in connection with the acceptance or administration of this Guarantee
Agreement, including the costs and expenses of defending itself against any
claim or liability in connection with the exercise or performance of any of its
powers or duties hereunder. The Guarantee Trustee will not claim or exact any
lien or charge on any Guarantee Agreement as a result of any amount due to it
under this Guarantee Agreement.

     The provisions of this Section 3.3 shall survive the termination of this
Guarantee Agreement or the resignation or removal of the Guarantee Trustee.

                                GUARANTEE TRUSTEE

SECTION 4.1 Guarantee Trustee; Eligibility

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

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

          (ii) be a Person that is eligible pursuant to the Trust Indenture Act
     to act as such and has a combined capital of at least 50 million U.S.
     dollars ($50,000,000), and shall be a corporation meeting the requirements
     of Section 310(c) of the Trust Indenture Act. If such corporation publishes
     reports of condition at least annually, pursuant to law or to the
     requirements of the supervising or examining authority, then, for the
     purposes of this Section 4.1(a)(ii), the combined capital and surplus of
     such corporation shall be deemed to be its combined capital and surplus as
     set forth in its most recent report of condition so published.

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

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

<PAGE>

     (b) The Guarantee Trustee shall not be removed in accordance with Section
4.2(a) until a Successor Guarantee Trustee has been appointed and has accepted
such appointment by written instrument executed by such Successor Guarantee
Trustee and delivered to the Guarantor.

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

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

                                   ARTICLE V

SECTION 5.1 Guarantee

     The Guarantor irrevocably and unconditionally agrees to pay in full to the
Holders the Guarantee Payments (without duplication of amounts theretofore paid
by or on behalf of the Issuer), as and when due, regardless of any defense,
right of set-off or counterclaim that the Issuer may have or assert. The
Guarantor's obligation to make a Guarantee Payment may be satisfied by direct
payment of the required amounts by the Guarantor to the Holders or by causing
the Issuer, through the Debenture Issuer, to pay such amounts to the Holders.

SECTION 5.2 Waiver of Notice and Demand

     The Guarantor hereby waives notice of acceptance of this Guarantee
Agreement and of any liability to which it applies or may apply, presentment,
demand for payment, any right to require a proceeding first against the
Guarantee Trustee, Issuer or any other Person before proceeding against the
Guarantor, protest, notice of nonpayment, notice of dishonor, notice of
redemption and all other notices and demands.

SECTION 5.3 Obligations Not Affected

     The obligations, covenants, agreements and duties of the Guarantor under
this Guarantee shall in no way be affected or impaired by reason of the
happening from time to time of any of the following:

<PAGE>

     (a) the release or waiver, by operation of law or otherwise, of the
performance or observance by the Issuer of any express or implied agreement,
covenant, term or condition relating to the Preferred Securities to be performed
or observed by the Issuer;

     (b) the extension of time for the payment by the Issuer of all or any
portion of the Distributions, Redemption Price, Liquidation Distribution or any
other sums payable under the terms of the Preferred Securities or the extension
of time for the performance of any other obligation under, arising out of, or in
connection with, the Preferred Securities (other than an extension of time for
payment of Distributions, Redemption Price, Liquidation Distribution or other
sum payable that results from the extension of any interest payment period on
the Debentures or so provided by the Indenture);

     (c) any failure, omission, delay or lack of diligence on the part of the
Holders to enforce, assert or exercise any right, privilege, power or remedy
conferred on the Holders pursuant to the terms of the Preferred Securities, or
any action on the part of the Issuer 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 of,
or other similar proceedings affecting, the Issuer or any of the assets of the
Issuer;

     (e) any invalidity of, or defect or deficiency in, the Preferred
Securities;

     (f) the settlement or compromise of any obligation guaranteed hereby or
hereby incurred; or

     (g) any other circumstance whatsoever that might otherwise constitute a
legal or equitable discharge or defense of a guarantor, it being the intent of
this Section 5.3 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 to give notice to, or obtain
the consent of, the Guarantor with respect to the happening of any of the
foregoing.

SECTION 5.4 Rights of Holders

     The Guarantor expressly acknowledges that: (i) this Guarantee Agreement
will be deposited with the Guarantee Trustee to be held for the benefit of the
Holders; (ii) the Guarantee Trustee has the right to enforce this Guarantee
Agreement on behalf of the Holders; (iii) the Holders of a Majority in
liquidation preference of the Preferred Securities have the right to direct the
time, method and place of conducting any proceeding for any remedy available to
the Guarantee Trustee in respect of this Guarantee Agreement or to direct the
exercise of any trust or power conferred upon the Guarantee Trustee under this
Guarantee Agreement; and (iv) any Holder may, to the extent permitted by law,
institute a legal proceeding directly against the Guarantor to enforce its
rights under this Guarantee Agreement, without first instituting a legal
proceeding against the Guarantee Trustee, the Issuer or any other Person. The
Guarantor waives


                                       12
<PAGE>

any right or remedy to require that any action on this Guarantee Agreement be
brought first against the Issuer or any other Person or entity before proceeding
directly against the Guarantor.

SECTION 5.5 Guarantee of Payment

     This Guarantee creates a guarantee of payment and not of collection. This
Guarantee Agreement will not be discharged except by payment of the Guarantee
Payments in full (without duplication of amounts theretofore paid by the Issuer)
or upon distribution of Debentures to Holders as provided in the Trust
Agreement.

SECTION 5.6 Subrogation

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

SECTION 5.7 Independent Obligations

     The Guarantor acknowledges that its obligations hereunder are independent
of the obligations of the Issuer with respect to the Preferred Securities, and
that the Guarantor shall be liable as principal and as debtor hereunder to make
Guarantee Payments pursuant to the terms of this Guarantee Agreement
notwithstanding the occurrence of any event referred to in subsections (a)
through (g), inclusive, of Section 5.3 hereof.

SECTION 5.8 Net Payments

     All Guarantee Payments required to be made hereunder shall be made by the
Guarantor without withholding or deduction at source for, or on account of, any
present or future taxes, fees, duties, assessments or governmental charges of
whatever nature imposed or levied by or on behalf of the Cayman Islands or
Bermuda (each, a "taxing jurisdiction") or any political subdivision or taxing
authority thereof or therein, unless such taxes, fees, duties, assessments or
governmental charges are required to be withheld or deducted by (i) the laws (or
any regulations or ruling promulgated thereunder) of a taxing jurisdiction or
any political subdivision or taxing authority thereof or therein or (ii) an
official position regarding the application, administration, interpretation or
enforcement of any such laws, regulations or rulings (including, without
limitation, a holding by a court of competent jurisdiction or by a taxing
authority in a taxing jurisdiction or any political subdivision thereof). If a
withholding or deduction at source is required, the Guarantor shall, subject to
certain limitations and exceptions set forth below, pay to the Holder of any
Preferred Security such Additional Amounts as may be necessary so that every
Guarantee Payment made to such Holder, after such withholding or deduction,
shall not be less than the amount provided for in this Guarantee Agreement to be
then due and payable; provided,


                                       13
<PAGE>

however, that the Guarantor shall not be required to make payment of such
Additional Amounts for or on account of:

     (1) any tax, fee, duty, assessment or governmental charge of whatever
nature which would not have been imposed but for the fact that such Holder: (A)
was a resident, domiciliary or national of, or engaged in business or maintained
a permanent establishment or was physically present in, the relevant taxing
jurisdiction or any political subdivision thereof or otherwise had some
connection with the relevant taxing jurisdiction other than by reason of the
mere ownership of, or receipt of payment under, such Preferred Security; (B)
presented such Preferred Security for payment in the relevant taxing
jurisdiction or any political subdivision thereof, unless such Preferred
Security could not have been presented for payment elsewhere; or (C) presented
such Preferred Security more than thirty (30) days after the date on which the
payment in respect of such Preferred Security first became due and payable or
provided for, whichever is later, except to the extent that the Holder would
have been entitled to such Additional Amounts if it had presented such Preferred
Security for payment on any day within such period of thirty (30) days;

     (2) any estate, inheritance, gift, sale, transfer, personal property or
similar tax, assessment or other governmental charge;

     (3) any tax, assessment or other governmental charge that is imposed or
withheld by reason of the failure by the Holder or the beneficial owner of such
Preferred Security to comply with any reasonable request by the Guarantor or the
Trust addressed to the Holder within 90 days of such request (A) to provide
information concerning the nationality, residence or identity of the Holder or
such beneficial owner or (B) to make any declaration or other similar claim or
satisfy any information or reporting requirement, which, in the case of (A) or
(B), is required or imposed by statute, treaty, regulation or administrative
practice of the relevant taxing jurisdiction or any political subdivision
thereof as a precondition to exemption from all or part of such tax, assessment
or other governmental charge; or

     (4) any combination of items (1), (2) and (3);

nor shall Additional Amounts be paid with respect to any Guarantee Payment to
any Holder who is a fiduciary or partnership or other than the sole beneficial
owner of the related Preferred Security to the extent such payment would be
required by the laws of the relevant taxing jurisdiction (or any political
subdivision or relevant taxing authority thereof or therein) to be included in
the income for tax purposes of a beneficiary or partner or settlor with respect
to such fiduciary or a member of such partnership or a beneficial owner who
would not have been entitled to such Additional Amounts had it been the Holder
of such Preferred Security.

                                   ARTICLE VI

                       LIMITATION OF TRANSACTIONS; RANKING

SECTION 6.1 Limitation of Transactions

     The Guarantor hereby covenants and agrees that, so long as any Preferred
Securities remain outstanding, it will not, and will not permit any of its
Subsidiaries (including the Debenture Issuer) to, (a) declare or pay any
dividends or distributions on, or redeem, purchase,


                                       14
<PAGE>

acquire or make a liquidation payment with respect to, any of the outstanding
capital stock of the Debenture Issuer or the Guarantor, as the case may be, or
(b) make any payment of principal of, interest or premium, if any, on or repay,
repurchase or redeem any debt security of the Debenture Issuer or the Guarantor,
as the case may be, that ranks junior in interest to the Debentures or the
guarantee in respect thereof, as the case may be, or make any guarantee payments
with respect to any guarantee by the Debenture Issuer or the Guarantor, as the
case may be, of the debt securities of any Subsidiary of the Debenture Issuer or
the Guarantor, as the case may be, if such guarantee ranks junior in interest to
the Debentures or the guarantee in respect thereof, as the case may be (other
than (i) dividends or distributions on the Capital Stock (as defined in the
Indenture) of the Debenture Issuer paid or made to the Guarantor and dividends
or distributions in Common Stock (as defined in the Indenture) of the Debenture
Issuer or the Guarantor, as the case may be, (ii) redemptions or purchases of
any rights outstanding under a shareholder rights plan of the Debenture Issuer
or the Guarantor, as the case may be, or the declaration of a dividend of such
rights or the issuance of stock under such plans in the future, (iii) payments
under any preferred securities guarantee, and (iv) purchases of Common Stock
related to the issuance of Common Stock under any benefit plans of the Debenture
Issuer or the Guarantor, as the case may be, for its respective directors,
officers or employees) if at such time (1) there shall have occurred any event
of which the Debenture Issuer or the Guarantor, as the case may be, has actual
knowledge that (A) with the giving of notice or the lapse of time or both, would
constitute an Event of Default under the Indenture and (B) in respect of which
the Debenture Issuer or the Guarantor, as the case may be, shall not have taken
reasonable steps to cure, (2) the Guarantor shall be in default with respect to
its payment of any obligations under this Guarantee Agreement or (3) the
Debenture Issuer shall have given notice of its election to begin an Extension
Period (as defined in the Indenture) with respect to the Debentures as provided
in the Indenture and shall not have rescinded such notice, or such Extension
Period, or any extension thereof, shall be continuing.

SECTION 6.2 Ranking

     This Guarantee will constitute an unsecured obligation of the Guarantor and
will rank subordinate and junior in right of payment to all Senior Indebtedness
of the Guarantor.

SECTION 6.3 Pari Passu Guarantees

     This Guarantee Agreement shall rank pari passu with any similar Guarantee
Agreements issued by the Guarantor on behalf of holders of preferred securities
of any other ACE Capital Trust or any trust, partnership or other entity
affiliated with the Guarantor which is a financing vehicle of the Guarantor or
any Affiliate of the Guarantor in connection with the issuance by such entity of
preferred securities or other securities which are similar to preferred
securities that are guaranteed by the Guarantor pursuant to an instrument that
ranks pari passu with or junior in right of payment to this Guarantee Agreement.

distribution of the Debentures to all Holders in exchange for the Preferred
Securities or (iii) full payment of the amounts payable in accordance with the

with respect to the Preferred Securities or under this Guarantee Agreement.

Guarantee Trustee shall exercise such of the rights and powers vested in it by
this Guarantee Agreement, and use the same degree of care and skill in its
exercise thereof, as a prudent person would exercise or use under the
circumstances in the conduct of his or her own affairs.

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

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

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

               (B) in the absence of bad faith on the part of the Guarantee
          Trustee, the Guarantee Trustee may conclusively rely, as to the truth
          of the statements and the correctness of the opinions expressed
          therein, upon any certificates or opinions furnished to the Guarantee
          Trustee and conforming to the requirements of this Guarantee
          Agreement; but in the case of any such certificates or opinions that
          by any provision hereof are specifically required to be furnished to
          the Guarantee Trustee, the Guarantee Trustee shall be under a duty to
          examine the same to


                                       7
<PAGE>

          determine whether or not they conform to the requirements of this
          Guarantee Agreement;

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

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

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

SECTION 3.2    Certain Rights of the Guarantee Trustee

     (a)  Subject to the provisions of Section 3.1:

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

          (ii) Any direction or act of the Guarantor contemplated by this
     Guarantee Agreement shall be sufficiently evidenced by an Officer's
     Certificate unless otherwise prescribed herein.

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

          (iv) The Guarantee Trustee may consult with competent legal counsel,
     and the written advice or opinion of such counsel with respect to legal
     matters shall be full and complete authorization and protection in respect
     of any action taken, suffered or omitted to be taken by it hereunder in
     good faith and in accordance with such advice or opinion.


                                       8
<PAGE>

     Such counsel may be counsel to the Guarantor or any of its Affiliates and
     may include any of its employees. The Guarantee Trustee shall have the
     right at any time to seek instructions concerning the administration of
     this Guarantee Agreement from any court of competent jurisdiction.

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

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

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

          (viii) Any action taken by the Guarantee Trustee or its agents
     hereunder shall bind the Holders, and the signature of the Guarantee
     Trustee or its agents alone shall be sufficient and effective to perform
     any such action. No third party shall be required to inquire as to the
     authority of the Guarantee Trustee to so act or as to its compliance with
     any of the terms and provisions of this Guarantee Agreement, both of which
     shall be conclusively evidenced by the Guarantee Trustee's or its agent's
     taking such action.

          (ix) Whenever in the administration of this Guarantee Agreement the
     Guarantee Trustee shall deem it desirable to receive instructions with
     respect to enforcing any remedy or right or taking any other action
     hereunder, the Guarantee Trustee (A) may request instructions from the
     Holders of a Majority in liquidation preference of the Preferred
     Securities, (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.

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


                                       9
<PAGE>

permissive power or authority available to the Guarantee Trustee shall be
construed to be a duty to act in accordance with such power and authority.

SECTION 3.3    Indemnity

     The Guarantor agrees to indemnify the Guarantee Trustee for, and to hold it
harmless against, any loss, liability or expense incurred without negligence,
bad faith or willful misconduct on the part of the Guarantee Trustee, arising
out of or in connection with the acceptance or administration of this Guarantee
Agreement, including the costs and expenses of defending itself against any
claim or liability in connection with the exercise or performance of any of its
powers or duties hereunder. The Guarantee Trustee will not claim or exact any
lien or charge on any Guarantee Agreement as a result of any amount due to it
under this Guarantee Agreement.

     The provisions of this Section 3.3 shall survive the termination of this
Guarantee Agreement or the resignation or removal of the Guarantee Trustee.

                                   ARTICLE IV

                                GUARANTEE TRUSTEE

     to act as such and has a combined capital of at least 50 million U.S.
     dollars ($50,000,000), and shall be a corporation meeting the requirements
     of Section 310(c) of the Trust Indenture Act. If such corporation publishes
     reports of condition at least annually, pursuant to law or to the
     requirements of the supervising or examining authority, then, for the
     purposes of this Section 4.1(a)(ii), the combined capital and surplus of
     such corporation shall be deemed to be its combined capital and surplus as
     set forth in its most recent report of condition so published.

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

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

<PAGE>

     (b) The Guarantee Trustee shall not be removed in accordance with Section
4.2(a) until a Successor Guarantee Trustee has been appointed and has accepted
such appointment by written instrument executed by such Successor Guarantee
Trustee and delivered to the Guarantor.

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

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

                                   ARTICLE V

                                    GUARANTEE

SECTION 5.1    Guarantee

     The Guarantor irrevocably and unconditionally agrees to pay in full to the
Holders the Guarantee Payments (without duplication of amounts theretofore paid
by or on behalf of the Issuer), as and when due, regardless of any defense,
right of set-off or counterclaim that the Issuer may have or assert. The
Guarantor's obligation to make a Guarantee Payment may be satisfied by direct
payment of the required amounts by the Guarantor to the Holders or by causing
the Issuer, through the Debenture Issuer, to pay such amounts to the Holders.

SECTION 5.2    Waiver of Notice and Demand

     The Guarantor hereby waives notice of acceptance of this Guarantee
Agreement and of any liability to which it applies or may apply, presentment,
demand for payment, any right to require a proceeding first against the
Guarantee Trustee, Issuer or any other Person before proceeding against the
Guarantor, protest, notice of nonpayment, notice of dishonor, notice of
redemption and all other notices and demands.

SECTION 5.3    Obligations Not Affected

     The obligations, covenants, agreements and duties of the Guarantor under
this Guarantee shall in no way be affected or impaired by reason of the
happening from time to time of any of the following:


                                       11
<PAGE>

     (a) the release or waiver, by operation of law or otherwise, of the
performance or observance by the Issuer of any express or implied agreement,
covenant, term or condition relating to the Preferred Securities to be performed
or observed by the Issuer;

     (b) the extension of time for the payment by the Issuer of all or any
portion of the Distributions, Redemption Price, Liquidation Distribution or any
other sums payable under the terms of the Preferred Securities or the extension
of time for the performance of any other obligation under, arising out of, or in
connection with, the Preferred Securities (other than an extension of time for
payment of Distributions, Redemption Price, Liquidation Distribution or other
sum payable that results from the extension of any interest payment period on
the Debentures or so provided by the Indenture);

     (c) any failure, omission, delay or lack of diligence on the part of the
Holders to enforce, assert or exercise any right, privilege, power or remedy
conferred on the Holders pursuant to the terms of the Preferred Securities, or
any action on the part of the Issuer 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 of,
or other similar proceedings affecting, the Issuer or any of the assets of the
Issuer;

     (e) any invalidity of, or defect or deficiency in, the Preferred
Securities;

     (f) the settlement or compromise of any obligation guaranteed hereby or
hereby incurred; or

     (g) any other circumstance whatsoever that might otherwise constitute a
legal or equitable discharge or defense of a guarantor, it being the intent of
this Section 5.3 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 to give notice to, or obtain
the consent of, the Guarantor with respect to the happening of any of the
foregoing.

SECTION 5.4    Rights of Holders

     The Guarantor expressly acknowledges that: (i) this Guarantee Agreement
will be deposited with the Guarantee Trustee to be held for the benefit of the
Holders; (ii) the Guarantee Trustee has the right to enforce this Guarantee
Agreement on behalf of the Holders; (iii) the Holders of a Majority in
liquidation preference of the Preferred Securities have the right to direct the
time, method and place of conducting any proceeding for any remedy available to
the Guarantee Trustee in respect of this Guarantee Agreement or to direct the
exercise of any trust or power conferred upon the Guarantee Trustee under this
Guarantee Agreement; and (iv) any Holder may, to the extent permitted by law,
institute a legal proceeding directly against the Guarantor to enforce its
rights under this Guarantee Agreement, without first instituting a legal
proceeding against the Guarantee Trustee, the Issuer or any other Person. The
Guarantor waives


                                       12
<PAGE>

any right or remedy to require that any action on this Guarantee Agreement be
brought first against the Issuer or any other Person or entity before proceeding
directly against the Guarantor.

SECTION 5.5    Guarantee of Payment

     This Guarantee creates a guarantee of payment and not of collection. This
Guarantee Agreement will not be discharged except by payment of the Guarantee
Payments in full (without duplication of amounts theretofore paid by the Issuer)
or upon distribution of Debentures to Holders as provided in the Trust
Agreement.

SECTION 5.6    Subrogation

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

SECTION 5.7    Independent Obligations

     The Guarantor acknowledges that its obligations hereunder are independent
of the obligations of the Issuer with respect to the Preferred Securities, and
that the Guarantor shall be liable as principal and as debtor hereunder to make
Guarantee Payments pursuant to the terms of this Guarantee Agreement
notwithstanding the occurrence of any event referred to in subsections (a)
through (g), inclusive, of Section 5.3 hereof.

SECTION 5.8    Net Payments

     All Guarantee Payments required to be made hereunder shall be made by the
Guarantor without withholding or deduction at source for, or on account of, any
present or future taxes, fees, duties, assessments or governmental charges of
whatever nature imposed or levied by or on behalf of the Cayman Islands or
Bermuda (each, a "taxing jurisdiction") or any political subdivision or taxing
authority thereof or therein, unless such taxes, fees, duties, assessments or
governmental charges are required to be withheld or deducted by (i) the laws (or
any regulations or ruling promulgated thereunder) of a taxing jurisdiction or
any political subdivision or taxing authority thereof or therein or (ii) an
official position regarding the application, administration, interpretation or
enforcement of any such laws, regulations or rulings (including, without
limitation, a holding by a court of competent jurisdiction or by a taxing
authority in a taxing jurisdiction or any political subdivision thereof). If a
withholding or deduction at source is required, the Guarantor shall, subject to
certain limitations and exceptions set forth below, pay to the Holder of any
Preferred Security such Additional Amounts as may be necessary so that every
Guarantee Payment made to such Holder, after such withholding or deduction,
shall not be less than the amount provided for in this Guarantee Agreement to be
then due and payable; provided,


                                       13
<PAGE>

however, that the Guarantor shall not be required to make payment of such
Additional Amounts for or on account of:

     (1) any tax, fee, duty, assessment or governmental charge of whatever
nature which would not have been imposed but for the fact that such Holder: (A)
was a resident, domiciliary or national of, or engaged in business or maintained
a permanent establishment or was physically present in, the relevant taxing
jurisdiction or any political subdivision thereof or otherwise had some
connection with the relevant taxing jurisdiction other than by reason of the
mere ownership of, or receipt of payment under, such Preferred Security; (B)
presented such Preferred Security for payment in the relevant taxing
jurisdiction or any political subdivision thereof, unless such Preferred
Security could not have been presented for payment elsewhere; or (C) presented
such Preferred Security more than thirty (30) days after the date on which the
payment in respect of such Preferred Security first became due and payable or
provided for, whichever is later, except to the extent that the Holder would
have been entitled to such Additional Amounts if it had presented such Preferred
Security for payment on any day within such period of thirty (30) days;

     (2) any estate, inheritance, gift, sale, transfer, personal property or
similar tax, assessment or other governmental charge;

     (3) any tax, assessment or other governmental charge that is imposed or
withheld by reason of the failure by the Holder or the beneficial owner of such
Preferred Security to comply with any reasonable request by the Guarantor or the
Trust addressed to the Holder within 90 days of such request (A) to provide
information concerning the nationality, residence or identity of the Holder or
such beneficial owner or (B) to make any declaration or other similar claim or
satisfy any information or reporting requirement, which, in the case of (A) or
(B), is required or imposed by statute, treaty, regulation or administrative
practice of the relevant taxing jurisdiction or any political subdivision
thereof as a precondition to exemption from all or part of such tax, assessment
or other governmental charge; or

     (4) any combination of items (1), (2) and (3);

nor shall Additional Amounts be paid with respect to any Guarantee Payment to
any Holder who is a fiduciary or partnership or other than the sole beneficial
owner of the related Preferred Security to the extent such payment would be
required by the laws of the relevant taxing jurisdiction (or any political
subdivision or relevant taxing authority thereof or therein) to be included in
the income for tax purposes of a beneficiary or partner or settlor with respect
to such fiduciary or a member of such partnership or a beneficial owner who
would not have been entitled to such Additional Amounts had it been the Holder
of such Preferred Security.

                                   ARTICLE VI

                       LIMITATION OF TRANSACTIONS; RANKING

SECTION 6.1    Limitation of Transactions

     The Guarantor hereby covenants and agrees that, so long as any Preferred
Securities remain outstanding, it will not, and will not permit any of its
Subsidiaries (including the Debenture Issuer) to, (a) declare or pay any
dividends or distributions on, or redeem, purchase,


                                       14
<PAGE>

acquire or make a liquidation payment with respect to, any of the outstanding
capital stock of the Debenture Issuer or the Guarantor, as the case may be, or
(b) make any payment of principal of, interest or premium, if any, on or repay,
repurchase or redeem any debt security of the Debenture Issuer or the Guarantor,
as the case may be, that ranks junior in interest to the Debentures or the
guarantee in respect thereof, as the case may be, or make any guarantee payments
with respect to any guarantee by the Debenture Issuer or the Guarantor, as the
case may be, of the debt securities of any Subsidiary of the Debenture Issuer or
the Guarantor, as the case may be, if such guarantee ranks junior in interest to
the Debentures or the guarantee in respect thereof, as the case may be (other
than (i) dividends or distributions on the Capital Stock (as defined in the
Indenture) of the Debenture Issuer paid or made to the Guarantor and dividends
or distributions in Common Stock (as defined in the Indenture) of the Debenture
Issuer or the Guarantor, as the case may be, (ii) redemptions or purchases of
any rights outstanding under a shareholder rights plan of the Debenture Issuer
or the Guarantor, as the case may be, or the declaration of a dividend of such
rights or the issuance of stock under such plans in the future, (iii) payments
under any preferred securities guarantee, and (iv) purchases of Common Stock
related to the issuance of Common Stock under any benefit plans of the Debenture
Issuer or the Guarantor, as the case may be, for its respective directors,
officers or employees) if at such time (1) there shall have occurred any event
of which the Debenture Issuer or the Guarantor, as the case may be, has actual
knowledge that (A) with the giving of notice or the lapse of time or both, would
constitute an Event of Default under the Indenture and (B) in respect of which
the Debenture Issuer or the Guarantor, as the case may be, shall not have taken
reasonable steps to cure, (2) the Guarantor shall be in default with respect to
its payment of any obligations under this Guarantee Agreement or (3) the
Debenture Issuer shall have given notice of its election to begin an Extension
Period (as defined in the Indenture) with respect to the Debentures as provided
in the Indenture and shall not have rescinded such notice, or such Extension
Period, or any extension thereof, shall be continuing.

SECTION 6.2    Ranking

     This Guarantee will constitute an unsecured obligation of the Guarantor and
will rank subordinate and junior in right of payment to all Senior Indebtedness
of the Guarantor.

SECTION 6.3    Pari Passu Guarantees

     This Guarantee Agreement shall rank pari passu with any similar Guarantee
Agreements issued by the Guarantor on behalf of holders of preferred securities
of any other ACE Capital Trust or any trust, partnership or other entity
affiliated with the Guarantor which is a financing vehicle of the Guarantor or
any Affiliate of the Guarantor in connection with the issuance by such entity of
preferred securities or other securities which are similar to preferred
securities that are guaranteed by the Guarantor pursuant to an instrument that
ranks pari passu with or junior in right of payment to this Guarantee Agreement.

     This Guarantee shall terminate and be of no further force and effect upon
(i) full payment of the Redemption Price of all Preferred Securities, (ii) the
distribution of the Debentures to all Holders in exchange for the Preferred
Securities or (iii) full payment of the amounts payable in accordance with the

this Guarantee Agreement will continue to be effective or will be reinstated, as
the case may be, if at any time any Holder must restore payment of any sums paid
with respect to the Preferred Securities or under this Guarantee Agreement.

benefit of the Holders, and the Guarantee Trustee shall not transfer this
Guarantee Agreement to any Person except a Holder exercising his or her rights
pursuant to Section 5.4(iv) or to a Successor Guarantee Trustee on acceptance by
such Successor Guarantee Trustee of its appointment to act as Successor
Guarantee Trustee. The right, title and interest of the Guarantee Trustee shall
automatically vest in any Successor Guarantee Trustee, upon acceptance by such

cessation of title shall be effective whether or not conveyancing documents have
been executed and delivered pursuant to the appointment of such Successor
Guarantee Trustee.

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

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

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

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

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

               (B) in the absence of bad faith on the part of the Guarantee
          Trustee, the Guarantee Trustee may conclusively rely, as to the truth
          of the statements and the correctness of the opinions expressed
          therein, upon any certificates or opinions furnished to the Guarantee
          Trustee and conforming to the requirements of this Guarantee
          Agreement; but in the case of any such certificates or opinions that
          by any provision hereof are specifically required to be furnished to
          the Guarantee Trustee, the Guarantee Trustee shall be under a duty to
          examine the same to


                                       7
<PAGE>

          determine whether or not they conform to the requirements of this
          Guarantee Agreement;

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

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

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

SECTION 3.2    Certain Rights of the Guarantee Trustee

     (a) Subject to the provisions of Section 3.1:

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

          (ii) Any direction or act of the Guarantor contemplated by this
     Guarantee Agreement shall be sufficiently evidenced by an Officer's
     Certificate unless otherwise prescribed herein.

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

          (iv) The Guarantee Trustee may consult with competent legal counsel,
     and the written advice or opinion of such counsel with respect to legal
     matters shall be full and complete authorization and protection in respect
     of any action taken, suffered or omitted to be taken by it hereunder in
     good faith and in accordance with such advice or opinion.


                                       8
<PAGE>

     Such counsel may be counsel to the Guarantor or any of its Affiliates and
     may include any of its employees. The Guarantee Trustee shall have the
     right at any time to seek instructions concerning the administration of
     this Guarantee Agreement from any court of competent jurisdiction.

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

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

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

          (viii) Any action taken by the Guarantee Trustee or its agents
     hereunder shall bind the Holders, and the signature of the Guarantee
     Trustee or its agents alone shall be sufficient and effective to perform
     any such action. No third party shall be required to inquire as to the
     authority of the Guarantee Trustee to so act or as to its compliance with
     any of the terms and provisions of this Guarantee Agreement, both of which
     shall be conclusively evidenced by the Guarantee Trustee's or its agent's
     taking such action.

          (ix) Whenever in the administration of this Guarantee Agreement the
     Guarantee Trustee shall deem it desirable to receive instructions with
     respect to enforcing any remedy or right or taking any other action
     hereunder, the Guarantee Trustee (A) may request instructions from the
     Holders of a Majority in liquidation preference of the Preferred
     Securities, (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.

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


                                       9
<PAGE>

permissive power or authority available to the Guarantee Trustee shall be
construed to be a duty to act in accordance with such power and authority.

SECTION 3.3    Indemnity

     The Guarantor agrees to indemnify the Guarantee Trustee for, and to hold it
harmless against, any loss, liability or expense incurred without negligence,
bad faith or willful misconduct on the part of the Guarantee Trustee, arising
out of or in connection with the acceptance or administration of this Guarantee
Agreement, including the costs and expenses of defending itself against any
claim or liability in connection with the exercise or performance of any of its
powers or duties hereunder. The Guarantee Trustee will not claim or exact any
lien or charge on any Guarantee Agreement as a result of any amount due to it
under this Guarantee Agreement.

Guarantee Agreement or the resignation or removal of the Guarantee Trustee.

     such corporation shall be deemed to be its combined capital and surplus as
     set forth in its most recent report of condition so published.

take effect until a Successor Guarantee Trustee has been appointed and has
accepted such appointment by instrument in writing executed by such Successor
Guarantee Trustee and delivered to the Guarantor and the resigning Guarantee
Trustee.

     (d) If no Successor Guarantee Trustee shall have been appointed and
accepted appointment as provided in this Section 4.2 within 60 days after
delivery to the Guarantor of an instrument of resignation, the resigning

Holders the Guarantee Payments (without duplication of amounts theretofore paid
by or on behalf of the Issuer), as and when due, regardless of any defense,
right of set-off or counterclaim that the Issuer may have or assert. The
Guarantor's obligation to make a Guarantee Payment may be satisfied by direct
payment of the required amounts by the Guarantor to the Holders or by causing
the Issuer, through the Debenture Issuer, to pay such amounts to the Holders.

SECTION 5.2    Waiver of Notice and Demand

     The Guarantor hereby waives notice of acceptance of this Guarantee
Agreement and of any liability to which it applies or may apply, presentment,

or observed by the Issuer;

     (b) the extension of time for the payment by the Issuer of all or any
portion of the Distributions, Redemption Price, Liquidation Distribution or any
other sums payable under the terms of the Preferred Securities or the extension
of time for the performance of any other obligation under, arising out of, or in
connection with, the Preferred Securities (other than an extension of time for

     (c) any failure, omission, delay or lack of diligence on the part of the
Holders to enforce, assert or exercise any right, privilege, power or remedy
conferred on the Holders pursuant to the terms of the Preferred Securities, or
any action on the part of the Issuer 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

Securities;

     (f) the settlement or compromise of any obligation guaranteed hereby or
hereby incurred; or

     (g) any other circumstance whatsoever that might otherwise constitute a
legal or equitable discharge or defense of a guarantor, it being the intent of
this Section 5.3 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 to give notice to, or obtain
the consent of, the Guarantor with respect to the happening of any of the
foregoing.

SECTION 5.4    Rights of Holders

     The Guarantor expressly acknowledges that: (i) this Guarantee Agreement
will be deposited with the Guarantee Trustee to be held for the benefit of the
Holders; (ii) the Guarantee Trustee has the right to enforce this Guarantee
Agreement on behalf of the Holders; (iii) the Holders of a Majority in
liquidation preference of the Preferred Securities have the right to direct the
time, method and place of conducting any proceeding for any remedy available to
the Guarantee Trustee in respect of this Guarantee Agreement or to direct the
exercise of any trust or power conferred upon the Guarantee Trustee under this
Guarantee Agreement; and (iv) any Holder may, to the extent permitted by law,
institute a legal proceeding directly against the Guarantor to enforce its
rights under this Guarantee Agreement, without first instituting a legal
proceeding against the Guarantee Trustee, the Issuer or any other Person. The
Guarantor waives


                                       12

any right or remedy to require that any action on this Guarantee Agreement be
brought first against the Issuer or any other Person or entity before proceeding
directly against the Guarantor.

SECTION 5.5    Guarantee of Payment

     This Guarantee creates a guarantee of payment and not of collection. This
Guarantee Agreement will not be discharged except by payment of the Guarantee
Payments in full (without duplication of amounts theretofore paid by the Issuer)
or upon distribution of Debentures to Holders as provided in the Trust
Agreement.

SECTION 5.6    Subrogation

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

SECTION 5.7    Independent Obligations

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

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

SECTION 5.8    Net Payments

     All Guarantee Payments required to be made hereunder shall be made by the
Guarantor without withholding or deduction at source for, or on account of, any
present or future taxes, fees, duties, assessments or governmental charges of
whatever nature imposed or levied by or on behalf of the Cayman Islands or
Bermuda (each, a "taxing jurisdiction") or any political subdivision or taxing
authority thereof or therein, unless such taxes, fees, duties, assessments or
governmental charges are required to be withheld or deducted by (i) the laws (or
any regulations or ruling promulgated thereunder) of a taxing jurisdiction or
any political subdivision or taxing authority thereof or therein or (ii) an
official position regarding the application, administration, interpretation or
enforcement of any such laws, regulations or rulings (including, without
limitation, a holding by a court of competent jurisdiction or by a taxing
authority in a taxing jurisdiction or any political subdivision thereof). If a
withholding or deduction at source is required, the Guarantor shall, subject to
certain limitations and exceptions set forth below, pay to the Holder of any
Preferred Security such Additional Amounts as may be necessary so that every
Guarantee Payment made to such Holder, after such withholding or deduction,
shall not be less than the amount provided for in this Guarantee Agreement to be
then due and payable; provided,


                                       13
<PAGE>

however, that the Guarantor shall not be required to make payment of such
Additional Amounts for or on account of:

     (1) any tax, fee, duty, assessment or governmental charge of whatever
nature which would not have been imposed but for the fact that such Holder: (A)
was a resident, domiciliary or national of, or engaged in business or maintained
a permanent establishment or was physically present in, the relevant taxing
jurisdiction or any political subdivision thereof or otherwise had some
connection with the relevant taxing jurisdiction other than by reason of the
mere ownership of, or receipt of payment under, such Preferred Security; (B)
presented such Preferred Security for payment in the relevant taxing
jurisdiction or any political subdivision thereof, unless such Preferred
Security could not have been presented for payment elsewhere; or (C) presented
such Preferred Security more than thirty (30) days after the date on which the
payment in respect of such Preferred Security first became due and payable or
provided for, whichever is later, except to the extent that the Holder would
have been entitled to such Additional Amounts if it had presented such Preferred
Security for payment on any day within such period of thirty (30) days;

     (2) any estate, inheritance, gift, sale, transfer, personal property or
similar tax, assessment or other governmental charge;

     (3) any tax, assessment or other governmental charge that is imposed or
withheld by reason of the failure by the Holder or the beneficial owner of such
Preferred Security to comply with any reasonable request by the Guarantor or the
Trust addressed to the Holder within 90 days of such request (A) to provide
information concerning the nationality, residence or identity of the Holder or
such beneficial owner or (B) to make any declaration or other similar claim or
satisfy any information or reporting requirement, which, in the case of (A) or
(B), is required or imposed by statute, treaty, regulation or administrative
practice of the relevant taxing jurisdiction or any political subdivision
thereof as a precondition to exemption from all or part of such tax, assessment
or other governmental charge; or

     (4) any combination of items (1), (2) and (3);

nor shall Additional Amounts be paid with respect to any Guarantee Payment to
any Holder who is a fiduciary or partnership or other than the sole beneficial
owner of the related Preferred Security to the extent such payment would be
required by the laws of the relevant taxing jurisdiction (or any political
subdivision or relevant taxing authority thereof or therein) to be included in
the income for tax purposes of a beneficiary or partner or settlor with respect
to such fiduciary or a member of such partnership or a beneficial owner who
would not have been entitled to such Additional Amounts had it been the Holder
of such Preferred Security.

                       LIMITATION OF TRANSACTIONS; RANKING

SECTION 6.1    Limitation of Transactions

     The Guarantor hereby covenants and agrees that, so long as any Preferred
Securities remain outstanding, it will not, and will not permit any of its
Subsidiaries (including the Debenture Issuer) to, (a) declare or pay any
dividends or distributions on, or redeem, purchase,


                                       14
<PAGE>

acquire or make a liquidation payment with respect to, any of the outstanding
capital stock of the Debenture Issuer or the Guarantor, as the case may be, or
(b) make any payment of principal of, interest or premium, if any, on or repay,
repurchase or redeem any debt security of the Debenture Issuer or the Guarantor,
as the case may be, that ranks junior in interest to the Debentures or the
guarantee in respect thereof, as the case may be, or make any guarantee payments
with respect to any guarantee by the Debenture Issuer or the Guarantor, as the
case may be, of the debt securities of any Subsidiary of the Debenture Issuer or
the Guarantor, as the case may be, if such guarantee ranks junior in interest to
the Debentures or the guarantee in respect thereof, as the case may be (other
than (i) dividends or distributions on the Capital Stock (as defined in the
Indenture) of the Debenture Issuer paid or made to the Guarantor and dividends
or distributions in Common Stock (as defined in the Indenture) of the Debenture
Issuer or the Guarantor, as the case may be, (ii) redemptions or purchases of
any rights outstanding under a shareholder rights plan of the Debenture Issuer
or the Guarantor, as the case may be, or the declaration of a dividend of such
rights or the issuance of stock under such plans in the future, (iii) payments
under any preferred securities guarantee, and (iv) purchases of Common Stock
related to the issuance of Common Stock under any benefit plans of the Debenture
Issuer or the Guarantor, as the case may be, for its respective directors,
officers or employees) if at such time (1) there shall have occurred any event
of which the Debenture Issuer or the Guarantor, as the case may be, has actual
knowledge that (A) with the giving of notice or the lapse of time or both, would
constitute an Event of Default under the Indenture and (B) in respect of which
the Debenture Issuer or the Guarantor, as the case may be, shall not have taken
reasonable steps to cure, (2) the Guarantor shall be in default with respect to
its payment of any obligations under this Guarantee Agreement or (3) the
Debenture Issuer shall have given notice of its election to begin an Extension
Period (as defined in the Indenture) with respect to the Debentures as provided
in the Indenture and shall not have rescinded such notice, or such Extension
Period, or any extension thereof, shall be continuing.

SECTION 6.2    Ranking

     This Guarantee will constitute an unsecured obligation of the Guarantor and
will rank subordinate and junior in right of payment to all Senior Indebtedness
of the Guarantor.

SECTION 6.3    Pari Passu Guarantees

     This Guarantee Agreement shall rank pari passu with any similar Guarantee
Agreements issued by the Guarantor on behalf of holders of preferred securities
of any other ACE Capital Trust or any trust, partnership or other entity
affiliated with the Guarantor which is a financing vehicle of the Guarantor or
any Affiliate of the Guarantor in connection with the issuance by such entity of

     Re:  ACE Limited
          Registration Statement on Form S-3
          ----------------------------------

Dear Sirs:

     We have acted as Cayman Islands counsel to ACE Limited (the "Company") in
connection with the registration of Ordinary Shares, Preferred Shares, Debt
Securities, Warrants to Purchase Ordinary Shares (the "Ordinary Share
Warrants"), Warrants to Purchase Preferred Shares (the "Preferred Share
Warrants"), Warrants to Purchase Debt Securities (the "Debt Warrants"; the
Ordinary Share Warrants, Preferred Share Warrants and Debt Warrants are
collectively referred to as the "Warrants") and Stock Purchase Contracts of the
Company under the Securities Act of 1933, as amended, in accordance with the
Company's Registration Statement on Form S-3 filed with the Securities and
Exchange Commission on May 20, 1999, as amended by Pre-Effective Amendment No. 1
to the Registration Statement filed with the Securities and Exchange Commission
on August 6, 1999, as amended by Pre-Effective Amendment No. 2 filed with the
Securities and Exchange Commission on August 12, 1999 (collectively, the
"Registration Statement").

     In rendering the opinions expressed herein, we have examined and are
familiar with the Registration Statement as an exhibit to which this opinion
will be filed.  We have also examined such other documents and instruments
(including the Company's Memorandum and Articles of Association, as amended) and
have made such further investigation as we have deemed necessary or appropriate
in connection with this opinion.

     We have relied in giving this opinion on certifications, given by the
Company's officers.  We have assumed that there will be no intervening changes
to the structure of the proposed issue, nor to the Company's Memorandum or
Articles of Association, the laws of the Cayman Islands or any other relevant
matter.

     Based upon and subject to the foregoing, and having regard for legal
considerations which we deem relevant, we are of the opinion that:

     (i)   On the basis that the contractual consideration (being worth not less
           than the par value) for the Ordinary Shares (including the Ordinary
           Shares issuable upon the exercise of the Ordinary Share Warrants) is
           duly transferred to, and received by, the Company, such Ordinary
           Shares issued or to be issued may properly be registered in the
           Company's share register and credited as fully paid under Cayman
           Islands law.

     (ii)  On the basis that the contractual consideration (being worth not less
           than the par value) for the Preferred Shares (including the Preferred
           Shares issuable upon the exercise of the Preferred Share Warrants),
           when the terms of such Preferred Shares are set, is duly transferred
           to, and received by, the Company, such Preferred Shares issued or to
           be issued may properly be registered in the Company's share register
           and credited as fully paid under Cayman Islands law.

     (iii) Fully paid shares are not subject to further calls or assessments by
           the Company.

     (iv)  The Company has been incorporated as an exempted company under the
           Companies Law (1995 Revision) of the Cayman Islands and the liability
           of its shareholders is limited to the amount, if any, unpaid on their
           shares (per Clause 5 of the Company's Memorandum of Association).  On
<PAGE>

            the basis that all such shares are fully paid, there is no rule of
            Cayman Islands law that would impose any further liability on
            persons holding shares in the Company, merely by reason of such
            shareholding.

     (v)    The ACE INA Senior Indenture is duly authorized by ACE.

     (vi)   The ACE INA Subordinated Indenture is duly authorized by ACE.

     (vii)  The Guaranty is duly authorized by ACE.

     (viii) The ACE Senior Indenture is duly authorized by ACE.

     (ix)   The ACE Senior Notes are duly authorized by ACE.

     (x)    The ACE Subordinated Indenture is duly authorized by ACE.

     (xi)   The ACE Subordinated Notes are duly authorized by ACE.

     (xii)  The Warrant Agreements are duly authorized by ACE.

     (xiii) The Warrants, when the terms of such are set by the Pricing
            Committee of ACE, will be duly authorized by ACE.

     (xiv)  The Stock Purchase Contracts are duly authorized by ACE.

     We hereby consent to the filing of this opinion as an exhibit to the
Registration Statement and to all references to this firm in such Registration
Statement.

                                Yours faithfully,

          Registration Statement on Form S-3
          ----------------------------------

Dear Ladies and Gentlemen:

     We have represented ACE Limited ("ACE"), a Cayman Islands company limited
by shares, in connection with the preparation and filing with the Securities and
Exchange Commission under the Securities Act of 1933, as amended, of a
Registration Statement on Form S-3 (the "Registration Statement") relating to
ACE's Ordinary Shares, Preferred Shares, Debt Securities, Warrants to Purchase
Ordinary Shares (the "Ordinary Share Warrants"), Warrants to Purchase Preferred
Shares (the "Preferred Share Warrants"), Warrants to Purchase Debt Securities

Debt Warrants are collectively referred to as the "Warrants") and Stock Purchase
Contracts.  We have also represented ACE INA Holdings Inc. ("ACE INA"), a
Delaware corporation, in connection with the preparation and filing with the
Securities and Exchange Commission under the Securities Act of 1933, as amended,
of the Registration Statement relating to ACE INA's Debt Securities, which are
fully and unconditionally guaranteed (the "Guaranty") by ACE.

     The ACE INA Debt Securities are to be issued under a senior indenture (the
"ACE INA Senior Indenture") among ACE INA, ACE and The First National Bank of
Chicago, as trustee, or a subordinated indenture (the "ACE INA Subordinated
Indenture" and, together with the ACE INA Senior Indenture, the "ACE INA
Indentures") among ACE INA, ACE and The First National Bank of Chicago, as
trustee, in each case to be entered into prior to the issuance of the ACE INA
Debt Securities, with certain terms of the ACE INA Debt Securities to be
established by or pursuant to resolutions of the Board of Directors of ACE and
ACE INA as part of the corporate action taken and to be taken relating to the
issuance of the ACE INA Debt Securities.

     The ACE Debt Securities are to be issued under a senior indenture (the "ACE
Senior Indenture") among ACE and The First National Bank of Chicago, as trustee,
or a subordinated indenture (the "ACE Subordinated  Indenture" and, together
with the ACE Senior Indenture, the "ACE Indentures") among ACE and The First
National Bank of Chicago, as trustee, in each case to be entered into prior to
the issuance of the ACE Debt Securities, with certain terms of the ACE Debt
Securities to be established by or pursuant to resolutions of the Board of
Directors of ACE as part of the corporate action taken and to be taken relating
to the issuance of the ACE Debt Securities.

     The Warrants are to be issued pursuant to the terms of one or more warrant
agreements (the "Warrant Agreements") to be entered into prior to the issuance
of the Warrants, with certain terms of the Warrants to be established by or
pursuant to resolutions of the Board of Directors of ACE as part of the
corporate action taken and to be taken relating to the issuance of the Warrants.

     In rendering the opinions expressed herein, we have examined and are
familiar with (i) the Registration Statements as an exhibit to which this
opinion will be filed, (ii) the form of ACE INA Senior Indenture filed as an
<PAGE>

exhibit to the Registration Statement, (iii) the form of ACE INA Senior Note
(including the form of ACE Guaranty) attached as an exhibit to the form of the
ACE INA Senior Indenture, (iv) the form of ACE INA Subordinated Indenture filed
as an exhibit to the Registration Statement, (v) the form of ACE INA
Subordinated Note (including the form of ACE Guaranty) attached as an exhibit to
the form of ACE INA Subordinated Indenture, (vi) the form of ACE Senior
Indenture filed as an exhibit to the Registration Statement, (vii) the form of
ACE Senior Note attached as an exhibit to the form of ACE Senior Indenture,

Registration Statement, (ix) the form of ACE Subordinated Note attached as an

Agreements attached as an exhibit to the Registration Statement.  We have also
examined such other documents and instruments and have made such further
investigations as we have deemed necessary or appropriate in connection with
this opinion.

     Based upon and subject to the foregoing, and having regard for legal
considerations which we deem relevant, we are of the opinion that:

  (i)     ACE INA Holdings Inc. is a corporation duly organized and validly
          existing in good standing under the laws of the State of Delaware.

  (ii)    The ACE INA Senior Indenture, assuming the due authorization thereof
          by ACE and when duly executed and delivered, will constitute a valid
          and binding obligation of ACE INA enforceable against ACE INA and ACE
          in accordance with its terms, subject to applicable bankruptcy,
          insolvency, reorganization, moratorium and other laws affecting the
          enforceability of creditors' rights generally and to court decisions
          with respect thereto and to general principles of equity (regardless
          of whether such enforceability is considered in a proceeding in equity
          or at law).

  (iii)   The ACE INA Senior Notes, when duly executed and delivered and
          authenticated in accordance with the Indenture and when payment
          therefor is received, will constitute valid and legally binding
          obligations of ACE INA entitled to the benefits provided by the ACE
          INA Senior Indenture.

  (iv)    The ACE INA Subordinated Indenture, assuming the due authorization
          thereof by ACE and when duly executed and delivered, will constitute a
          valid and binding obligation of ACE INA enforceable against ACE INA
          and ACE in accordance with its terms, subject to applicable
          bankruptcy, insolvency, reorganization, moratorium and other laws
          affecting the enforceability of creditors' rights generally and to
          court decisions with respect thereto and to general principles of
          equity (regardless of whether such enforceability is considered in a
          proceeding in equity or at law).

  (v)     The ACE INA Subordinated Notes, when duly executed and delivered and
          authenticated in accordance with the Indenture and when payment
          therefor is received, will constitute valid and legally binding
          obligations of ACE INA entitled to the benefits provided by the ACE
          INA Subordinated Indenture.

  (vi)    The Guaranty, assuming the due authorization thereof and when duly
          executed and delivered and endorsed on an ACE INA Senior Note or ACE
          INA Subordinated Note, will be enforceable in accordance with its
          terms, subject to applicable bankruptcy, insolvency, reorganization,
          moratorium and other laws affecting the enforceability of creditors'
          rights generally and to court decisions with respect thereto and to
          general principles of equity (regardless of whether such
          enforceability is considered in a proceeding in equity or at law).

  (vii)   The ACE Senior Indenture, assuming the due authorization thereof and
          when duly executed and delivered, will be enforceable against ACE in
          accordance with its terms, subject to applicable bankruptcy,
          insolvency, reorganization, moratorium and other laws affecting the
          enforceability of creditors' rights generally and to court decisions
          with respect thereto and to general principles
<PAGE>

          of equity (regardless of whether such enforceability is considered in
          a proceeding in equity or at law).

          Re:  ACE Capital Trust I

Ladies and Gentlemen:

          We have acted as special Delaware counsel for ACE INA Holdings Inc., a
Delaware corporation (the "Company"), ACE Limited, a Cayman Islands company
limited by shares ("ACE Limited"), and ACE Capital Trust I, a Delaware business
trust (the "Trust"), in connection with the matters set forth herein.  At your
request, this opinion is being furnished to you.

          For purposes of giving the opinions hereinafter set forth, our
examination of documents has been limited to the examination of originals or
copies of the following:

          (a) The Certificate of Trust of the Trust, dated as of May 19, 1999
(the "Certificate"), as filed in the office of the Secretary of State of the
State of Delaware (the "Secretary of State") on May 19, 1999;

          (b) The Trust Agreement of the Trust, dated as of May 19, 1999 (the

named therein, as amended by the Assignment and Assumption Agreement and First
Amendment to the Original Trust Agreement, dated as of August 5, 1999, among the
Company, ACE Limited and the trustees of the Trust named therein;

          (c) A form of Amended and Restated Trust Agreement of the Trust

as depositor, the trustees of the Trust named therein, and the
holders, from time to time, of undivided beneficial interests in the assets of
the Trust, attached as an exhibit to the Registration Statement (as defined
below);

          (d) The Registration Statement (the "Initial Registration Statement")
on Form S-3 (Registration No. 333-78841), filed by the Trust, the Company and
others with the Securities and Exchange Commission on May 20, 1999, as amended
by Pre-Effective Amendment No. 1 to the Initial Registration Statement,  filed
by the Trust, the Company and others with the Securities and Exchange Commission
on August 6, 1999 ("Amendment No.  1"), as further amended by Pre-Effective
Amendment No. 2 to the Initial Registration Statement, as proposed to be filed
by the Trust, the Company and others with the Securities and Exchange Commission
on or about August 11, 1999 ("Amendment No.  2"), including a related
preliminary prospectus (the "Prospectus"), relating to the Preferred Securities
of the Trust representing undivided beneficial interests in the assets of the
Trust (each, a "Preferred Security" and collectively, the "Preferred
Securities") (the Initial Registration Statement as amended by Amendment No. 1
and Amendment No. 2 being hereinafter referred to as the "Registration
Statement"); and

          (e) A Certificate of Good Standing for the Trust, dated August 11,
1999, obtained from the Secretary of State.

          Capitalized terms used herein and not otherwise defined are used as
defined in the Trust Agreement.

          For purposes of this opinion, we have not reviewed any documents other
than the documents listed in paragraphs (a) through (e) above.  In particular,
we have not reviewed any document (other than the documents listed in paragraphs
(a) through (e) above) that is referred to in or incorporated by reference into
the documents reviewed by us.  We have assumed that there exists no provision in
any document that we have not reviewed that is inconsistent with the opinions
stated herein.  We have conducted no independent factual investigation of our
own but rather have relied solely upon the foregoing documents, the statements
and information set forth therein and the additional matters recited or assumed
herein, all of which we have assumed to be true, complete and accurate in all
material respects.

          With respect to all documents examined by us, we have assumed (i) the
authenticity of all documents submitted to us as authentic originals, (ii) the
conformity with the originals of all documents submitted to us as copies or
forms, and (iii) the genuineness of all signatures.
<PAGE>

ACE Capital Trust I

          For purposes of this opinion, we have assumed (i) that the Trust
Agreement and the Certificate are in full force and effect and have not been
amended, (ii) except to the extent provided in paragraph 1 below, the due
creation or due organization or due formation, as the case may be, and valid
existence in good standing of each party to the documents examined by us under
the laws of the jurisdiction governing its creation, organization or formation,
(iii) the legal capacity of natural persons who are parties to the documents
examined by us, (iv) that each of the parties to the documents examined by us
has the power and authority to execute and deliver, and to perform its
obligations under, such documents, (v) the due authorization, execution and
delivery by all parties thereto of all documents examined by us, (vi) the
receipt by each Person to whom a Preferred Security is to be issued by the Trust
(collectively, the "Preferred Security Holders") of a Preferred Securities
Certificate for such Preferred Security and the payment for the Preferred
Security acquired by it, in accordance with the Trust Agreement and the
Registration Statement, (vii) that the Preferred Securities are issued and sold
to the Preferred Security Holders in accordance with the Trust Agreement and the
Registration Statement, and (viii) that Bank One Delaware, Inc. satisfies for
the Trust Section 3807 of the Delaware Business Trust Act. We have not
participated in the preparation of the Registration Statement and assume no
responsibility for its contents.

          This opinion is limited to the laws of the State of Delaware
(excluding the securities laws of the State of Delaware), and we have not
considered and express no opinion on the laws of any other jurisdiction,
including federal laws and rules and regulations relating thereto.  Our opinions
are rendered only with respect to Delaware laws and rules, regulations and
orders thereunder that are currently in effect.

          Based upon the foregoing, and upon our examination of such questions
of law and statutes of the State of Delaware as we have considered necessary or
appropriate, and subject to the assumptions, qualifications, limitations and
exceptions set forth herein, we are of the opinion that:

          1.   The Trust has been duly created and is validly existing in good
standing as a business trust under the Delaware Business Trust Act.

          2.   The Preferred Securities will represent valid and, subject to the
qualifications set forth in paragraph 3 below, fully paid and nonassessable
undivided beneficial interests in the assets of the Trust.
<PAGE>

ACE Capital Trust I

          3.   The Preferred Security Holders, 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.  We note that the Preferred Security
Holders may be obligated to make payments as set forth in the Trust Agreement.

          We consent to the filing of this opinion with the Securities and
Exchange Commission as an exhibit to the Registration Statement.  In addition,
we hereby consent to the use of our name under the heading "Legal Opinions" in
the Prospectus.  In giving the foregoing consents, we do not thereby admit that
we come within the category of Persons whose consent is required under Section 7
of the Securities Act of 1933, as amended, or the rules and regulations of the
Securities and Exchange Commission thereunder.  Except as stated above, without
our prior written consent, this opinion may not be furnished or quoted to, or
relied upon by, any other Person for any purpose.
