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

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

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

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

         (b) The Holders of a Majority in liquidation amount of the Common
    Securities may, by vote, on behalf of the Holders


                                       10

   17



     of all of the Common Securities, waive any past Event of Default with
     respect to the Common Securities and its consequences, provided that, if
     the underlying Event of Default under the Indenture:

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

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

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

              (c) A waiver of an Event of Default under the Indenture by the
         Institutional Trustee at the direction of the Holders of the Preferred
         Securities, constitutes a waiver of the corresponding Event of Default
         under this Declaration. The foregoing provisions of this Section 2.6(c)
         shall be in


                                       11

   18



         lieu of Section 316(a)(1)(B) of the Trust Indenture Act and such
         Section 316(a)(1)(B) of the Trust Indenture Act is hereby expressly
         excluded from this Declaration and the Securities, as permitted by the
         Trust Indenture Act.

SECTION 2.7       Event of Default; Notice.

              (a) The Institutional Trustee shall, within 90 days after the
         occurrence of an Event of Default, transmit by mail, first class
         postage prepaid, to the Holders of the Securities, notices of all
         defaults with respect to the Securities actually known to a Responsible
         Officer of the Institutional Trustee, unless such defaults have been
         cured before the giving of such notice (the term "defaults" for the
         purposes of this Section 2.7(a) being hereby defined to be an Event of
         Default as defined in the Indenture, not including any periods of
         grace provided for therein and irrespective of the giving of any
         notice provided therein); provided that, except for a default in the
         payment of principal of (or premium, if any) or interest on any of the
         Debentures or in the payment of any sinking fund installment
         established for the Debentures, the Institutional Trustee shall be
         protected in withholding such notice if and so long as a Responsible
         Officer of the Institutional Trustee in good faith determines that the
         withholding of such notice is in the interests of the Holders of the
         Securities.

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

                  (i) a default under Sections 501 and 503 of the Indenture; or

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

                  (n) to take all action that may be necessary or appropriate

         existence, rights, franchises and privileges as a statutory business
         trust under the laws of the State of Delaware and of each other
         jurisdiction in which such existence is necessary to protect the
         limited liability of the Holders of the Preferred Securities or to
         enable the Trust to effect the purposes for which the Trust was
         created;


                                       15

                  (o) to take any action, not inconsistent with this Declaration
         or with applicable law, that the Regular Trustees determine in their

                  the Debentures will be treated as indebtedness of the
                  Debenture Issuer for United States federal income tax
                  purposes,

         provided that such action does not adversely affect the
         interests of Holders;

                  (p) to take all action necessary to cause all applicable tax

3.6 shall be reimbursed by the Debenture Issuer.

SECTION 3.7       Prohibition of Actions by the Trust and the
                  Trustees.

          (a) The Trust shall not, and the Trustees (including the Institutional

                                       16

   23



         other than as required or authorized by this Declaration. In
         particular, the Trust shall not and the Trustees (including the

                      (ii) acquire any assets other than as expressly provided
                  herein;

                      (iii) possess Trust property for other than a Trust
                  purpose;

                      (iv) make any loans or incur any indebtedness other than
                  loans represented by the Debentures;

                      (v) possess any power or otherwise act in such a way as to
                  vary the Trust assets or the terms of the Securities in any

                  amendment, modification or termination of the Indenture or the
                  Debentures where such consent shall be required unless the
                  Trust shall have received an opinion of counsel to the effect
                  that such modification will not cause more than an
                  insubstantial risk that for United States federal income tax
                  purposes the Trust will not be classified as a grantor trust.

SECTION 3.8       Powers and Duties of the Institutional Trustee.

          (a) The legal title to the Debentures shall be owned by and held of
     record in the name of the Institutional Trustee in trust for the benefit of
     the Holders of the Securities. The right, title and interest of the Instit-
     utional Trustee to the Debentures shall vest automatically in each Person
     who may hereafter be appointed as Institutional Trustee in accordance with
     Section 5.6. Such vesting and cessation of title shall be effective whether
     or not


                                       17

   24



         conveyancing documents with regard to the Debentures have
         been executed and delivered.

                  (b) The Institutional Trustee shall not transfer its right,
         title and interest in the Debentures to the Regular Trustees or to the
         Delaware Trustee (if the Institutional Trustee does not also act as
         Delaware Trustee).

                  (c)      The Institutional Trustee shall:

                           (i) establish and maintain a segregated non-interest
                  bearing trust account (the "Institutional Trustee Account") in
                  the name of and under the exclusive control of the
                  Institutional Trustee on behalf of the Holders of the
                  Securities and, upon the receipt of payments of funds made in
                  respect of the Debentures held by the Institutional Trustee,
                  deposit such funds into the Institutional Trustee Account and
                  make payments to the Holders of the Preferred Securities and
                  Holders of the Common Securities from the Institutional
                  Trustee Account in accordance with Section 6.1. Funds in the
                  Institutional Trustee Account shall be held uninvested until
                  disbursed in accordance with this Declaration. The
                  Institutional Trustee Account shall be an account that is
                  maintained with a banking institution the rating on whose
                  long-term unsecured indebtedness is at least equal to the
                  rating assigned to the Preferred Securities by a "nationally
                  recognized statistical rating organization," as that term is
                  defined for purposes of Rule 436(g)(2) under the Securities
                  Act;

                           (ii) engage in such ministerial activities as shall
                  be necessary or appropriate to effect the redemption of the
                  Preferred Securities and the Common Securities to the extent
                  the Debentures are redeemed or mature; and

                           (iii) upon written notice of distribution issued by
                  the Regular Trustees in accordance with the terms of the
                  Securities, engage in such ministerial activities as shall be
                  necessary or appropriate to effect the distribution of the
                  Debentures to Holders of Securities upon the occurrence of
                  certain special events (as may be defined in the terms of the
                  Securities) arising from a change in law or a change in legal
                  interpretation or other specified circumstances pursuant to
                  the terms of the Securities.

                  (d) The Institutional Trustee shall take all actions and
         perform such duties as may be specifically required of


                                       18

   25



         the Institutional Trustee pursuant to the terms of the
         Securities.

                  (e) The Institutional Trustee shall take any Legal Action
         which arises out of or in connection with an Event of Default of which
         a Responsible Officer of the Institutional Trustee has actual knowledge
         or the Institutional Trustee's duties and obligations under this
         Declaration or the Trust Indenture Act.

                  (f) The Institutional Trustee shall not resign as a Trustee
         unless either:

                      (i) the Trust has been completely liquidated and the
                  proceeds of the liquidation distributed to the Holders of
                  Securities pursuant to the terms of the Securities; or

                      (ii) a Successor Institutional Trustee has been appointed
                  and has accepted that appointment in accordance with Section
                  5.6.

                  (g) The Institutional Trustee shall have the legal power to
         exercise all of the rights, powers and privileges of a holder of
         Debentures under the Indenture and, if an Event of Default actually
         known to a Responsible Officer of the Institutional Trustee occurs and
         is continuing, the Institutional Trustee shall, for the benefit of
         Holders of the Securities, enforce its rights as holder of the Deben-
         tures subject to the rights of the Holders pursuant to the terms of
         such Securities.

                  (h) Subject to this Section 3.8, the Institutional Trustee
         shall have none of the duties, liabilities, powers or the authority of
         the Regular Trustees set forth in Section 3.6.

                  The Institutional Trustee must exercise the powers set forth
in this Section 3.8 in a manner that is consistent with the purposes and
functions of the Trust set out in Section 3.3, and the Institutional Trustee
shall not take any action that is inconsistent with the purposes and functions
of the Trust set out in Section 3.3.

SECTION 3.9       Certain Duties and Responsibilities of the Institutional
                  Trustee.

          (a) The Institutional Trustee, before the occurrence of any Event of
     Default and after the curing of all Events of Default that may have
     occurred, shall undertake to perform only such duties as are specifically
     set forth in this Declaration and no implied covenants shall be read into
     this


                                       19

   26



         Declaration against the Institutional Trustee. In case an Event of
         Default has occurred (that has not been cured or waived pursuant to
         Section 2.6) of which a Responsible Officer of the Institutional
         Trustee has actual knowledge, the Institutional Trustee shall exercise
         such of the rights and powers vested in it by this Declaration, and use
         the same degree of care and skill in their exercise, as a prudent
         person would exercise or use under the circumstances in the conduct of
         his or her own affairs.

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

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

                          (A) the duties and obligations of the Institutional
         Trustee shall be determined solely by the express provisions of this
         Declaration and the Institutional Trustee shall not be liable except
         for the performance of such duties and obligations as are specifically
         set forth in this Declaration, and no implied covenants or obligations
         shall be read into this Declaration against the Institutional Trustee;
         and

                          (B) in the absence of bad faith on the part of the
         Institutional Trustee, the Institutional 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
         Institutional Trustee and conforming to the requirements of this
         Declaration; but in the case of any such certificates or opinions that
         by any provision hereof are specifically required to be furnished to
         the Institutional Trustee, the Institutional Trustee shall be under a
         duty to examine the same to determine whether or not they conform to
         the requirements of this Declaration;

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

                      (iii) the Institutional 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


                                       20
   27


         liquidation amount of the Securities relating to the time, method and
         place of conducting any proceeding for any remedy available to the
         Institutional Trustee, or exercising any trust or power conferred upon
         the Institutional Trustee under this Declaration;

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

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

              (vi) the Institutional Trustee shall have no duty or liability for
         or with respect to the value, genuineness, existence or sufficiency of
         the Debentures or the payment of any taxes or assessments levied
         thereon or in connection therewith;

              (vii) the Institutional Trustee shall not be liable for any 
         interest on any money received by it except as it may otherwise agree
         with the Sponsor. Money held by the Institutional Trustee need not be
         segregated from other funds held by it except in relation to the
         Institutional Trustee Account maintained by the Institutional Trustee
         pursuant to Section 3.8(c)(i) and except to the extent otherwise
         required by law; and

              (viii) the Institutional Trustee shall not be responsible for 
         monitoring the compliance by the Regular Trustees or the Sponsor with
         their respective duties under this Declaration, nor shall the
         Institutional Trustee be liable for any default or misconduct of the
         Regular Trustees or the Sponsor.

         (a) The Trust may not consolidate, amalgamate, merge with or into, or 
    be replaced by, or convey, transfer or lease its properties and assets 
    substantially as an entirety, to any corporation or other body, except as 
    described in Section 3.15(b) and (c).

         (b) The Trust may, with the consent of the Regular Trustees and without
    the consent of the Holders of the Securities, consolidate, amalgamate, merge
    with or into, or be replaced by a trust organized as such under the laws of
    any State; provided that:

              (i) such successor entity (the "Successor Entity") either:

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

                   (B)     substitutes for the 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 with respect to Distributions and payments
    upon liquidation, redemption and otherwise;

              (ii) the Debenture Issuer expressly acknowledges a trustee of the
         Successor Entity possessing the same powers and duties as the 
         Institutional Trustee as the Holder of the Debentures;

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






                                       25
   32




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

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

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

              (vii) prior to such merger, consolidation, amalgamation or
         replacement, the Sponsor has received an opinion of a nationally
         recognized independent counsel to the Trust experienced in such matters
         to the effect that:

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

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

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

              (viii) the Sponsor guarantees the obligations of such Successor 
         Entity under the Successor Securities at least to the extent provided 
         by the Preferred Securities Guarantee.

         (c) Notwithstanding Section 3.15(b), the Trust shall not, except with 
    the consent of Holders of 100% in liquidation amount of the Securities,
    consolidate, amalgamate, merge with or into, or be replaced by any other
    entity or permit any other entity to consolidate, amalgamate, merge with or
    into, or replace it if in the opinion of a nationally recognized
    independent tax counsel experienced in such





                                       26
   33




    matters, such consolidation, amalgamation, merger or replacement would cause
    the Trust or Successor Entity to be classified as other than a grantor trust
    for United States federal income tax purposes.

    instrument executed by such Successor Institutional Trustee and delivered to
    the Regular Trustees and the Sponsor; and

              (ii) the Trustee that acts as Delaware Trustee shall not be 
         removed in accordance with this Section 5.6(a) until a successor
         Trustee possessing the qualifications to act as Delaware Trustee under

              (i) No such resignation of the Trustee that acts as the 
         Institutional Trustee shall be effective:

                   (A)     until a Successor Institutional Trustee has been
    appointed and has accepted such appointment by instrument executed by such
    Successor Institutional Trustee and delivered to the Trust, the Sponsor and
    the resigning Institutional Trustee; or

                   (B)     until the assets of the Trust have been completely

         appointed and has accepted such appointment by instrument executed by





                                       31
   38




         such Successor Delaware Trustee and delivered to the Trust,  the
         Sponsor and the resigning Delaware Trustee.

         (d) The Holders of the Common Securities shall use their best efforts
    to promptly appoint a Successor Delaware Trustee or Successor Institutional
    Trustee as the case may be if the Institutional Trustee or the Delaware
    Trustee delivers an instrument of resignation in accordance with this
    Section 5.6.

         (e) If no Successor Institutional Trustee or Successor Delaware Trustee
    shall have been appointed and accepted appointment as provided in this

    instrument of resignation, the resigning Institutional Trustee or Delaware
    Trustee, as applicable, may petition any court of competent jurisdiction for

    successor Delaware Trustee, as the case may be.

increased pursuant to Section 5.1, a vacancy shall occur. A resolution
certifying the existence of such vacancy by the Regular Trustees or, if there
are more than two, a majority of the Regular Trustees shall be conclusive 
evidence of the existence of such vacancy. The vacancy shall be filled with a
Trustee appointed in accordance with Section 5.6.

SECTION 5.8   Effect of Vacancies.

         The death, resignation, retirement, removal, bankruptcy, dissolution, 
liquidation, incompetence or incapacity to perform the duties of a Trustee shall
not operate to annul the Trust. Whenever a vacancy in the number of Regular
Trustees shall occur, until such vacancy is filled by the appointment of a
Regular Trustee in accordance with Section 5.6, the Regular Trustees in office,

Trustees or any committee thereof shall be hand delivered or otherwise delivered

the time, place and anticipated purposes of the meeting. The presence (whether
in person or by telephone) of a Regular Trustee at a meeting shall constitute a
waiver of notice of such meeting except where a Regular Trustee attends a
meeting for the express purpose of objecting to the transaction of any activity
on the ground that the meeting has not been law fully called or convened. Unless
provided otherwise in this Declaration, any action of the Regular Trustees may
be taken at a meeting by vote of a majority of the Regular Trustees present
(whether in person or by telephone) and eligible to vote with respect to such
matter, provided that a Quorum is present, or without a meeting by the unanimous
written consent of the Regular Trustees. In the event there is only one Regular
Trustee, any and all action of such Regular Trustee shall be evidenced by a
written consent of such Regular Trustee.

    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 3.6, including any registration statement or amendment thereto
    filed with the Commission, or making any other governmental filing; and

    to such of their number or to officers of the Trust the doing of such things
    and the execution of such instruments either in the name of the Trust or the
    names of the Regular Trustees or otherwise as the Regular 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.

Trustee, as the case may be, may be merged or converted or with which either may
be consolidated, or any corporation resulting from any merger, conversion or
consolidation to which the Institutional Trustee or the Delaware Trustee, as the
case may be, shall be a party, or any corporation succeeding to all or
substantially all the corporate trust business of the Institutional Trustee or

defined in the Indenture)), premium and/or principal on the Debentures held by
the Institutional Trustee (the amount of any such payment being a "Payment
Amount"), the Institutional Trustee shall and is directed, to the extent funds
are available for that purpose, to make a distribution (a "Distribution") of the
Payment Amount to Holders.

                             ISSUANCE OF SECURITIES

SECTION 7.1   General Provisions Regarding Securities.

         (a) The Regular Trustees shall, on behalf of the Trust, issue one class
    of preferred securities representing undivided beneficial interests in the
    assets of the Trust having such terms as are set forth in Annex I (the 
    "Preferred Securities") and one class of common securities representing
    undivided beneficial interests in the assets of the Trust having such terms
    as are set forth in Annex I (the "Common Securities"). The Trust shall issue
    no securities or other interests in the assets of the Trust other than the
    Preferred Securities and the Common Securities.

   41




         (b) The Certificates shall be signed on behalf of the Trust by a 
    Regular Trustee. Such signature shall be the manual signature of any present
    or any future Regular Trustee. In case any Regular Trustee of the Trust who
    shall have signed any of the Securities shall cease to be such Regular
    Trustee before the Certificates so signed shall be delivered by the Trust,
    such Certificates nevertheless may be delivered as though the person who
    signed such Certificates had not ceased to be such Regular Trustee; and any
    Certificate may be signed on behalf of the Trust by such persons who, at the
    actual date of execution of such Security, shall be the Regular Trustees of
    the Trust, although at the date of the execution and delivery of the
    Declaration any such person was not such a Regular Trustee. Certificates
    shall be printed, lithographed or engraved or may be produced in any other
    manner as is reasonably acceptable to the Regular Trustees, as evidenced by
    their execution there of, and may have such letters, numbers or other marks
    of identification or designation and such legends or endorsements as the
    Regular Trustees may deem appropriate, or as may be required to comply with
    any law or with any rule or regulation of any stock exchange on which
    Securities may be listed, or to conform to usage.

         (c) The consideration received by the Trust for the issuance of the 
    Securities shall constitute a contribution to the capital of the Trust and
    shall not constitute a loan to the Trust.

         (d) Upon issuance of the Securities as provided in this Declaration, 
    the Securities so issued shall be deemed to be validly issued, fully paid
    and non-assessable.

         (e) Every Person, by virtue of having become a Holder or a Preferred 
    Security Beneficial Owner in accordance with the terms of this Declaration,
    shall be deemed to have expressly assented and agreed to the terms of, and
    shall be bound by, this Declaration.

SECTION 7.2   Paying Agent.
         In the event that the Preferred Securities are not in book-entry only 
form, the Trust shall maintain in the borough of Manhattan, City of New York, 
State of New York, an office or agency where the Preferred Securities may be
presented for payment ("Paying Agent"), and any such Paying Agent shall comply
with Section 317(b) of the Trust Indenture Act. The Trust may appoint the Paying
Agent and may appoint one or more additional paying agents in such other
locations as it shall determine. The term "Paying Agent" includes any additional
paying agent. The Trust may change any Paying Agent without prior notice to any
Holder. The Trust shall notify the Institutional Trustee of the name and address
of any Agent not a party to this Declaration.





                                       35
   42




If the Trust fails to appoint or maintain another entity as Paying Agent, the
Institutional Trustee shall act as such. The Trust or any of its Affiliates may
act as Paying Agent. The Trust shall initially act as Paying Agent for the
Preferred Securities and the Common Securities.

                              TERMINATION OF TRUST

SECTION 8.1   Termination of Trust.

         (a)  The Trust shall terminate:

              (i)  upon the bankruptcy of the Holder of the Common Securities
         or the Sponsor;

              (ii) upon the filing of a certificate of dissolution or its 
         equivalent with respect to the Holder of the Common Securities or the

              (iii) upon the entry of a decree of judicial dissolution of the
         Holder of the Common Securities, the Sponsor or the Trust;

              (iv) when all of the Securities shall have been called for 
         redemption and the amounts necessary for redemption thereof shall have
         been paid to the Holders in accordance with the terms of the
         Securities;

              (v) upon the occurrence and continuation of a Special Event 
         pursuant to which the Trust shall have been dissolved in accordance
         with the terms of the Securities and all of the Debentures endorsed
         thereon shall have been distributed to the Holders of Securities in
         exchange for all of the Securities; or

              (vi) before the issuance of any Securities, with the consent of 
         all of the Regular Trustees and the Sponsor.

         (b) As soon as is practicable after the occurrence of an event referred
    to in Section 8.1(a) and upon completion of the winding-up of the Trust and
    its termination, the Trustees shall file a certificate of cancellation with
    the Secretary of State of the State of Delaware.





                                       36
   43





         (c) The provisions of Section 3.9 and Article X shall survive the 
    termination of the Trust.


                                   ARTICLE IX
                              TRANSFER OF INTERESTS

SECTION 9.1   Transfer of Securities.

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

         (b) Subject to this Article IX, Preferred Securities shall be freely
    transferable.

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

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

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

SECTION 9.2   Transfer of Certificates.

         The Regular Trustees shall provide for the registration of Certificates
and of transfers of Certificates, which will be effected without charge but only
upon payment (with such indemnity as the Regular Trustees may require) in
respect of any tax or other government charges that may be imposed in relation
to it. Upon surrender for registration of transfer of any Certificate, the
Regular Trustees shall cause one or more new Certificates to be issued in the
name of the designated transferee or transferees. Every Certificate surrendered
for registration of transfer shall be accompanied by a written instrument of
transfer in form satisfactory to the Regular Trustees duly executed by the
Holder or such Holder's attorney duly authorized in writing. Each Certificate
surrendered for registration of transfer shall be canceled by the Regular
Trustees. A transferee of a Certifi-


                                       37
   44

cate shall be entitled to the rights and subject to the obligations of a Holder
hereunder upon the receipt by such transferee of a Certificate. By acceptance o
a Certificate, each transferee shall be deemed to have agreed to be bound by
this Declaration.

SECTION 9.3   Deemed Security Holders.

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

SECTION 9.4   Book Entry Interests.

         Unless otherwise specified in the terms of the Preferred Securities,
the Preferred Securities Certificates, on original issuance, will be issued in
the form of one or more, fully registered, global Preferred Security
Certificates (each a "Global Certificate"), to be delivered to DTC, the initial
Clearing Agency, by, or on behalf of, the Trust. Such Global Certificate(s)
shall initially be registered on the books and records of the Trust in the name
of Cede & Co., the nominee of DTC, and no Preferred Security Beneficial Owner
will receive a definitive Preferred Security Certificate representing such
Preferred Security Beneficial Owner's interests in such Global Certificate(s),
except as provided in Section 9.7. Unless and until definitive, fully registered
Preferred Security Certificates (the "Definitive Preferred Security
Certificates") have been issued to the Preferred Security Beneficial Owners
pursuant to Section 9.7:

         (a)  the provisions of this Section 9.4 shall be in full force and 
    effect;

         (b) the Trust and the Trustees shall be entitled to deal with the
    Clearing Agency for all purposes of this Declaration (including the payment
    of Distributions on the Global Certificate(s) and receiving approvals, votes
    or consents hereunder) as the Holder of the Preferred Securities and the
    sole holder of the Global Certificate(s) and shall have no obligation to the
    Preferred Security Beneficial Owners;

         (c) to the extent that the provisions of this Section 9.4 conflict with
    any other provisions of this Declaration, the provisions of this Section 9.4
    shall control; and





                                       38
   45





         (d) the rights of the Preferred Security Beneficial Owners shall be
    exercised only through the Clearing Agency and shall be limited to those
    established by law and agreements between such Preferred Security
    Beneficial Owners and the Clearing Agency and/or the Clearing Agency
    Participants and receive and transmit payments of Distributions on the
    Global Certificates to such Clearing Agency Participants. DTC will make book
    entry transfers among the Clearing Agency Participants.

SECTION 9.5   Notices to Clearing Agency.

         Whenever a notice or other communication to the Preferred Security
Holders is required under this Declaration, unless and until Definitive
Preferred Security Certificates shall have been issued to the Preferred Security
Beneficial Owners pursuant to Section 9.7, the Regular Trustees shall give all
such notices and communications specified herein to be given to the Preferred
Security Holders to the Clearing Agency, and shall have no notice obligations to
the Preferred Security Beneficial Owners.

SECTION 9.6   Appointment of Successor Clearing Agency.

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

SECTION 9.7   Definitive Preferred Security Certificates.

         If:

         (a) a Clearing Agency elects to discontinue its services as securities
    depositary with respect to the Preferred Securities and a successor Clearing
    Agency is not appointed within 90 days after such discontinuance pursuant to
    Section 9.6; or

         (b) the Regular Trustees elect after consultation with the Sponsor to
    terminate the book entry system through the Clearing Agency with respect to
    the Preferred Securities,

then:

         (c) Definitive Preferred Security Certificates shall be prepared by the
    Regular Trustees on behalf of the Trust with respect to such Preferred
    Securities; and

         (d) upon surrender of the Global Certificate(s) by the Clearing Agency,
    accompanied by registration instructions,





                                       39
   46




    the Regular Trustees shall cause Definitive Certificates to be delivered to
    Preferred Security Beneficial Owners in accordance with the instructions of
    the Clearing Agency. Neither the Trustees nor the Trust shall be liable for
    any delay in delivery of such instructions and each of them may conclusively
    rely on and shall be protected in relying on, said instructions of the
    Clearing Agency. The Definitive Preferred Security Certificates shall be
    printed, lithographed or engraved or may be produced in any other manner as
    is reasonably acceptable to the Regular Trustees, as evidenced by their
    execution thereof, and may have such letters, numbers or other marks of
    identification or designation and such legends or endorsements as the
    Regular Trustees may deem appropriate, or as may be required to comply with
    any law or with any rule or regulation made pursuant thereto or with any
    rule or regulation of any stock exchange on which Preferred Securities may
    be listed, or to conform to usage.

SECTION 9.8   Mutilated, Destroyed, Lost or Stolen Certificates.

         If:

         (a) any mutilated Certificates should be surrendered to the Regular
    Trustees, or if the Regular Trustees shall receive evidence to their
    satisfaction of the destruction, loss or theft of any Certificate; and

         (b) there shall be delivered to the Regular Trustees such security or 
    indemnity as may be required by them to keep each of them harmless.

then, in the absence of notice that such Certificate shall have been acquired by
a bona fide purchaser, any Regular Trustee on behalf of the Trust shall execute
and deliver, in exchange for or in lieu of any such mutilated, destroyed, lost
or stolen Certificate, a new Certificate of like denomination. In connection
with the issuance of any new Certificate under this Section 9.8, the Regular
Trustees 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
Certificate issued pursuant to this Section shall constitute conclusive evidence
of an ownership interest in the relevant Securities, as if originally issued,
whether or not the lost, stolen or destroyed Certificate shall be found at any
time.

                    HOLDERS OF SECURITIES, TRUSTEES OR OTHERS

SECTION 10.1  Liability.

         (a) Except as expressly set forth in this Declaration, the Debentures,
    the Securities Guarantees and the terms of the Securities, the Sponsor shall
    not be:

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

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

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

         (c) Pursuant to Section 3803(a) of the Business Trust Act, the Holders
    of the Preferred Securities 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.

SECTION 10.2  Exculpation.

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

         (b) An Indemnified Person shall be fully protected in relying in good
    faith upon the records of the Trust and upon such information, opinions,
    reports or statements presented to the Trust by any Person as to matters the
    Indemnified Person reasonably believes are within such other Person's





                                       41
   48




    professional or expert competence and who has been selected with reasonable
    care by or on behalf of the Trust, including information, opinions, reports
    or statements as to the value and amount of the assets, liabilities,
    profits, losses, or any other facts pertinent to the existence and amount of
    assets from which Distributions to Holders of Securities might properly be
    paid.

SECTION 10.3  Fiduciary Duty.

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

         (b) Unless otherwise expressly provided herein:

              (i)  whenever a conflict of interest exists or arises between any
         Covered Persons; or

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

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

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






                                       42
   49




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

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

SECTION 10.4  Indemnification.

         (a) (i) The Debenture Issuer shall indemnify, to the full extent
    permitted by law, any Company Indemnified Person who was or is a party or is
    threatened to be made a party to any threatened, pending or completed
    action, suit or proceeding, whether civil, criminal, administrative or
    investigative (other than an action by or in the right of the Trust) by
    reason of the fact that he is or was a Company Indemnified Person against
    expenses (including attorneys' fees), judgments, fines and amounts paid in
    settlement actually and reasonably incurred by him in connection with such
    action, suit or proceeding if he acted in good faith and in a manner he
    reasonably believed to be in or not opposed to the best interests of the
    Trust, and, with respect to any criminal action or proceeding, had no
    reasonable cause to believe his conduct was unlawful. The termination of any
    action, suit or proceeding by judgment, order, settlement, conviction, or
    upon a plea of nolo contendere or its equivalent, shall not, of itself,
    create a presumption that the Company Indemnified Person did not act in good
    faith and in a manner which he reasonably believed to be in or not opposed
    to the best interests of the Trust, and, with respect to any criminal action
    or proceeding, had reasonable cause to believe that his conduct was
    unlawful.

              (ii) The Debenture Issuer shall indemnify, to the full extent
         permitted by law, any Company Indemnified Person who was or is a party
         or is threatened to be made a party to any threatened, pending or
         completed action or suit by or in the right of the Trust to procure a
         judgment in its favor by reason of the fact that he is or was a Company
         Indemnified Person against expenses (including attorneys' fees)
         actually and reasonably incurred by him in connection with the defense
         or settlement of such action or suit if he acted in good faith and in a
         manner he reasonably believed to





                                       43
   50




         be in or not opposed to the best interests of the Trust and except that
         no such indemnification shall be made in respect of any claim, issue or
         matter as to which such Company Indemnified Person shall have been
         adjudged to be liable to the Trust unless and only to the extent that
         the Court of Chancery of Delaware or the court in which such action or
         suit was brought shall determine upon application that, despite the
         adjudication of liability but in view of all the circumstances of the
         case, such person is fairly and reasonably entitled to indemnity for
         such expenses which such Court of Chancery or such other court shall
         deem proper.

              (iii) To the extent that a Company Indemnified Person shall be
         successful on the merits or otherwise (including dismissal of an action
         without prejudice or the settlement of an action without admission of
         liability) in defense of any action, suit or proceeding referred to in
         paragraphs (i) and (ii) of this Section 10.4(a), or in defense of any
         claim, issue or matter therein, he shall be indemnified, to the full
         extent permitted by law, against expenses (including attorneys' fees)
         actually and reasonably incurred by him in connection therewith.

              (iv) Any indemnification under paragraphs (i) and (ii) of this
         Section 10.4(a) (unless ordered by a court) shall be made by the
         Debenture Issuer only as authorized in the specific case upon a
         determination that indemnification of the Company Indemnified Person is
         proper in the circumstances because he has met the applicable standard
         of conduct set forth in paragraphs (i) and (ii). Such determination
         shall be made (1) by the Regular Trustees by a majority vote of a
         quorum consisting of such Regular Trustees who were not parties to
         such action, suit or proceeding, (2) if such a quorum is not
         obtainable, or, even if obtainable, if a quorum of disinterested
         Regular Trustees so directs, by independent legal counsel in a written
         opinion, or (3) by the Common Security Holder of the Trust.

              (v) Expenses (including attorneys' fees) incurred by a Company
         Indemnified Person in defending a civil, criminal, administrative or
         investigative action, suit or proceeding referred to in paragraphs (i)
         and (ii) of this Section 10.4(a) shall be paid by the Debenture Issuer
         in advance of the final disposition of such action, suit or proceeding
         upon receipt of an undertaking by or on behalf of such Company
         Indemnified Person to repay such amount if it shall ultimately be
         determined that he is not entitled to be indemnified by the Deben- 

                                       44
   51


         ture Issuer as authorized in this Section 10.4(a). Notwithstanding the
         foregoing, no advance shall be made by the Debenture Issuer if a
         determination is reasonably and promptly made (i) by the Regular
         Trustees by a majority vote of a quorum of disinterested Regular
         Trustees, (ii) if such a quorum is not obtainable, or, even if
         obtainable, if a quorum of disinterested Regular Trustees so directs,
         by independent legal counsel in a written opinion or (iii) the Common
         Security Holder of the Trust, that, based upon the facts known to the
         Regular Trustees, counsel or the Common Security Holder at the time
         such determination is made, such Company Indemnified Person acted in
         bad faith or in a manner that such person did not believe to be in or
         not opposed to the best interests of the Trust, or, with respect to any
         criminal proceeding, that such Company Indemnified Person believed or
         had reasonable cause to believe his conduct was unlawful. In no event
         shall any advance be made in instances where the Regular Trustees,
         independent legal counsel or Common Security Holder reasonably
         determine that such person deliberately breached his duty to the Trust
         or its Common or Preferred Security Holders.

              (vi) The indemnification and advancement of expenses provided by,
         or granted pursuant to, the other paragraphs of this Section 10.4(a)
         shall not be deemed exclusive of any other rights to which those
         seeking indemnification and advancement of expenses may be entitled
         under any agreement, vote of stockholders or disinterested directors of
         the Debenture Issuer or Preferred Security Holders of the Trust or
         otherwise, both as to action in his official capacity and as to action
         in another capacity while holding such office. All rights to
         indemnification under this Section 10.4(a) shall be deemed to be
         provided by a contract between the Debenture Issuer and each Company
         Indemnified Person who serves in such capacity at any time while this
         Section 10.4(a) is in effect. Any repeal or modification of this
         Section 10.4(a) shall not affect any rights or obligations then
         existing.

              (vii) The Debenture Issuer or the Trust may purchase and maintain
         insurance on behalf of any person who is or was a Company Indemnified
         Person against any liability asserted against him and incurred by him
         in any such capacity, or arising out of his status as such, whether or
         not the Debenture Issuer would have the power to indemnify him against
         such liability under the provisions of this Section 10.4(a).

              (viii)    For purposes of this Section 10.4(a), references to "the
         Trust" shall include, in addition to the resulting or surviving entity,
         any constituent entity (including any constituent of a constituent)
         absorbed in a consolidation or merger, so that any person who is or was
         a director, trustee, officer or employee of such constituent entity, or
         is or was serving at the request of such constituent entity as a
         director, trustee, officer, employee or agent of another entity, shall
         stand in the same position under the provisions of this Section 10.4(a)
         with respect to the resulting or surviving entity as he would have with
         respect to such constituent entity if its separate existence had
         continued.

              (ix)      The indemnification and advancement of expenses provided
         by, or granted pursuant to, this Section 10.4(a) shall, unless
         otherwise provided when authorized or ratified, continue as to a person
         who has ceased to be a Company Indemnified Person and shall inure to
         the benefit of the heirs, executors and administrators of such a
         person.

         (b)  The Debenture Issuer agrees to indemnify the (i) Institutional
    Trustee, (ii) the Delaware Trustee, (iii) any Affiliate of the Institutional
    Trustee and the Delaware Trustee, and (iv) any officers, directors,
    shareholders, members, partners, employees, representatives, custodians,
    nominees or agents of the Institutional Trustee and the Delaware Trustee
    (each of the Persons in (i) through (iv) being referred to as a "Fiduciary
    Indemnified Person") for, and to hold each Fiduciary Indemnified Person
    harmless against, any loss, liability or expense incurred without negligence
    or bad faith on its part, arising out of or in connection with the
    acceptance or administration or the trust or trusts hereunder, including the
    costs and expenses (including reasonable legal fees and expenses) of
    defending itself against or investigating any claim or liability in
    connection with the exercise or performance of any of its powers or duties
    hereunder. The obligation to indemnify as set forth in this Section 10.4(b)
    shall survive the satisfaction and discharge of this Declaration.

SECTION 10.5       Outside Businesses.

         Any Covered Person, the Sponsor, the Delaware Trustee and the
Institutional 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 of 
Securities shall have no rights by virtue of this Declaration in and to such
independent ventures or the income or profits derived


                                       46

   53



therefrom, and the pursuit of any such venture, even if competitive with the
business of the Trust, shall not be deemed wrongful or improper. No Covered
Person, the Sponsor, the Delaware Trustee, or the Institutional 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 any Covered Person, the Sponsor, the
Delaware Trustee and the Institutional 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 Covered Person,
the Delaware Trustee and the Institutional Trustee may engage or be interested
in any financial or other transaction with the Sponsor or any Affiliate of the
Sponsor, or may act as depositary for, trustee or agent for, or act on any
committee or body of holders of, securities or other obligations of the Sponsor
or its Affiliates.

SECTION 11.1       Fiscal Year.

         The fiscal year ("Fiscal Year") of the Trust shall be the calendar
year, or such other year as is required by the Code.

SECTION 11.2       Certain Accounting Matters.

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

         (b)  The Regular Trustees shall cause to be prepared and delivered to
    each of the Holders of Securities, within 90 days after the end of each
    Fiscal Year of the Trust, annual financial statements of the Trust,
    including a balance sheet of the Trust as of the end of such Fiscal Year,
    and the related statements of income or loss;



                                       47

   54
         (c)  The Regular Trustees shall cause to be duly prepared and 
    delivered to each of the Holders of Securities, any annual United States
    federal income tax information statement, required by the Code, containing
    such information with regard to the Securities held by each Holder as is 
    required by the Code and the Treasury Regulations. Notwithstanding any 
    right under the Code to deliver any such statement at a later date, the
    Regular Trustees shall endeavor to deliver all such statements within 30
    days after the end of each Fiscal Year of the Trust.

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

SECTION 11.3       Banking.

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

SECTION 11.4       Withholding.

         The Trust and the Regular Trustees shall comply with all withholding
requirements under United States federal, state and local law. The Trust shall
request, and the Holders shall provide to the Trust, such forms or certificates
as are necessary to establish an exemption from withholding with respect to each
Holder, and any representations and forms as shall reasonably be requested by
the Trust to assist it in determining the extent of, and in fulfilling, its
withholding obligations. The Regular Trustees shall file required forms with
applicable jurisdictions and, unless an exemption from withholding is properly
established by a Holder, shall remit amounts withheld with respect to the Holder
to applicable jurisdictions. To the extent that the Trust is required to
withhold and pay over any amounts to any authority with respect to distributions
or allocations to any Holder, the amount withheld shall be deemed to be a
distribution in the amount of the withholding to the Holder. In the event of any
amounts claimed over withholding, Holders shall be limited to an action against
the applicable jurisdiction. If the amount


                                       48

   55



required to be withheld was not withheld from actual Distributions made, the
Trust may reduce subsequent Distributions by the amount of such withholding.

SECTION 12.2       Meetings of the Holders of Securities; Action by Written 
                   Consent.

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

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

              (i)       notice of any such meeting shall be given to all the 
         Holders of Securities having a right to vote thereat at least 7 days
         and not more than 60 days before the date of such meeting. Whenever a
         vote, consent or approval of the Holders of Securities is permitted or
         required under this Declaration or the rules of any stock exchange on
         which the Preferred Securities are listed or admitted for trading, such
         vote, consent or approval may be given at a meeting of the Holders of
         Securities. Any action that may be taken at a meeting of the Holders of
         Securities may be taken without a meeting if a consent in writing
         setting


                                       51

   58



         forth the action so taken is signed by the Holders of Securities owning
         not less than the minimum amount of Securities in liquidation amount
         that would be necessary to authorize or take such action at a meeting
         at which all Holders of Securities having a right to vote thereon were
         present and voting. Prompt notice of the taking of action without a
         meeting shall be given to the Holders of Securities entitled to vote
         who have not consented in writing. The Regular Trustees may specify
         that any written ballot submitted to the Security Holder for the
         purpose of taking any action without a meeting shall be returned to the
         Trust within the time specified by the Regular Trustees;

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

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

              (iv)      unless the Business Trust Act, this Declaration, the 
         terms of the Securities, the Trust Indenture Act or the listing rules
         of any stock exchange on which the Preferred Securities are then listed
         or trading, otherwise provides, the Regular Trustees, in their sole
         discretion, shall establish all other provisions relating to meetings
         of Holders of Securities, including notice of the time, place or
         purpose of any meeting at which any matter is to be voted on by any
         Holders of Securities, waiver of any such notice, action by consent
         without a meeting, the establishment of a record date, quorum
         requirements, voting in person or by proxy or any other matter with
         respect to the exercise of any such right to vote.

                                    ANNEX I



                                    TERMS OF
                       8 5/8% TRUST PREFERRED SECURITIES
                            8 5/8% COMMON SECURITIES



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

         1.   Designation and Number.

         (a)  Preferred Securities. 4,000,000 Preferred Securities of the Trust
with an aggregate liquidation amount with respect to the assets of the Trust of
one-hundred million dollars ($100,000,000) and a liquidation amount with respect
to the assets of the Trust of $25 per preferred security, are hereby designated
for the purposes of identification only as "8 5/8% Trust Preferred Securities
("TRUPS(R)")" (the "Preferred Securities"). The Preferred Security Certificates
evidencing the Preferred Securities shall be substantially in the form of
Exhibit A-1 to the Declaration, with such changes and additions thereto or 
deletions therefrom as may be required by ordinary usage, custom or practice or 
to conform to the rules of any stock exchange on which the Preferred Securities 
are listed.

         (b)  Common Securities. 123,712 Common Securities of the Trust with an
aggregate liquidation amount with respect to the assets of the Trust of three
million ninety-two thousand eight hundred dollars ($3,092,800) and a liquidation
amount with respect to the assets of the Trust of $25 per common security, are
hereby designated for the purposes of identification only as "8 5/8% Common
Securities" (the "Common Securities" and, together with the Preferred
Securities, the "Securities"). The Common Security Certificates evidencing the
Common Securities shall be substantially in the form of Exhibit A-2 to the
Declaration, with such changes and additions thereto or deletions therefrom as
may be required by ordinary usage, custom or practice.

         2.   Distributions.


                                      I - 1

   65
         (a)  Distributions payable on each Security will be fixed at a rate per
annum of 8 5/8% (the "Coupon Rate") of the stated liquidation amount of $25 per
Security, such rate being the rate of interest payable on the Debentures to be
held by the Institutional Trustee. Distributions in arrears for more than one
quarter will bear interest thereon compounded quarterly at the Coupon Rate (to
the extent permitted by applicable law). The term "Distributions" as used herein
includes such cash distributions and any such interest payable unless otherwise
stated. A Distribution is payable only to the extent that payments are made in
respect of the Debentures held by the Institutional Trustee and to the extent
the Institutional Trustee has funds available therefor. The amount of
Distributions payable for any period will be computed for any full quarterly
Distribution period on the basis of a 360-day year of twelve 30-day months, and
for any period shorter than a full quarterly Distribution period for which
Distributions are computed, Distributions will be computed on the basis of the
actual number of days elapsed per 30-day month.

         (b)  Distributions on the Securities will be cumulative, will accrue
from November 18, 1998, and will be payable quarterly in arrears, on February
15, May 15, August 15, and November 15, of each year, commencing on February 15,
1999 except as otherwise described below. The Debenture Issuer has the right
under the Indenture to defer payments of interest by extending the interest
payment period from time to time on the Debentures for a period not exceeding 20
consecutive quarters (each an "Extension Period"), during which Extension
Period no interest shall be due and payable on the Debentures, provided that no
Extension Period shall last beyond the date of maturity of the Debentures. As a
consequence of such deferral, Distributions will also be deferred. Despite such
deferral, quarterly Distributions will continue to accrue with interest thereon
(to the extent permitted by applicable law) at the Coupon Rate compounded
quarterly during any such Extension Period. Prior to the termination of any such
Extension Period, the Debenture Issuer may further extend such Extension Period;
provided that such Extension Period together with all such previous and further
extensions thereof may not exceed 20 consecutive quarters. Payments of accrued
Distributions will be payable to Holders as they appear on the books and
records of the Trust on the first record date after the end of the Extension
Period. Upon the termination of any Extension Period and the payment of all
amounts then due, the Debenture Issuer may commence a new Extension Period,
subject to the above requirements.

         (c)  Distributions on the Securities will be payable to the Holders
thereof as they appear on the books and records of the Trust on the relevant
record dates. While the Preferred Securities remain in book-entry only form, the
relevant record


                                      I - 2

   66



dates shall be one Business Day prior to the relevant payment dates which
payment dates correspond to the interest payment dates on the Debentures.
Subject to any applicable laws and regulations and the provisions of the
Declaration, each such payment in respect of the Preferred Securities will be
made as described under the heading "Description of the Preferred Securities
- -- Book-Entry Only Issuance -- The Depository Trust Company" in the Prospectus
Supplement dated November 13, 1998, to the Prospectus dated March 18, 1998
(together, the "Prospectus"), of the Trust included in the Registration
Statement on Form S-3 of the Sponsor, the Trust and certain other business
trusts. The relevant record dates for the Common Securities shall be the same
record date as for the Preferred Securities. If the Preferred Securities shall
not continue to remain in book-entry only form, the relevant record dates for
the Preferred Securities, shall conform to the rules of any securities exchange
on which the securities are listed and, if none, shall be selected by the
Regular Trustees, which dates shall be at least one Business Day but less than
60 Business Days before the relevant payment dates, which payment dates
correspond to the interest payment dates on the Debentures. Distributions
payable on any Securities that are not punctually paid on any Distribution
payment date, as a result of the Debenture Issuer having failed to make a
payment under the Debentures, will cease to be payable to the Person in whose
name such Securities are registered on the relevant record date, and such
defaulted Distribution will instead be payable to the Person in whose name such
Securities are registered on the special record date or other specified date
determined in accordance with the Indenture. If any date on which Distributions
are payable on the Securities is not a Business Day, then payment of the 
Distribution payable on such date will be made on the next succeeding day that 
is a Business Day (and without any interest or other payment in respect of any 
such delay) except that, if such Business Day is in the next succeeding calendar
year, such payment shall be made on the immediately preceding Business Day, in
each case with the same force and effect as if made on such date.

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

         3.   Liquidation Distribution Upon Dissolution.

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


                                      I - 3

   67



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

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

         4.   Redemption and Distribution.

         (a)  Upon the maturity of the Debentures, the proceeds from such
repayment thereof shall simultaneously be applied to redeem all outstanding
Securities having an aggregate liquidation amount equal to the aggregate
principal amount of the Debentures so repaid at a redemption price of $25 per
Security plus an amount equal to accrued and unpaid Distributions thereon at the
date of the redemption, payable in cash (the "Redemption Price"). Upon the
redemption of the Debentures, whether in whole or in part (either at the option
of the Company or pursuant to a Special Event, as defined below), the proceeds
from such redemption shall simultaneously be applied to redeem Securities
having an aggregate liquidation amount equal to the aggregate principal amount
of the Debentures so redeemed at the Redemption Price; provided that holders of
the Securities will be given not less than 30 nor more than 60 days notice of
such redemption.

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

         (c)  The Debenture Issuer shall have the right, at any time, to 
dissolve the Trust and, after satisfaction of creditors, cause Debentures held
by the Institutional Trustee, having an aggregate principal amount equal to the
aggregate stated liquidation amount of, with an interest rate identical to the
Coupon Rate, and with accrued and unpaid interest equal to accrued and unpaid
Distributions on, the Securities outstanding at such time, to be distributed to
the Holders of the Securities in liquidation of such Holders' interests in the
Trust on a Pro Rata basis.

         The Debenture Issuer shall have the right, upon not less than 30 nor
more than 60 days notice, to redeem the Debentures, in whole but not in part,
for cash within 90 days follow-

                                     I - 4

   68

ing the occurrence of a Tax Event or an Investment Company Event (each as
defined below, and each a "Special Event"), and, following such redemption,
Securities with an aggregate liquidation amount equal to the aggregate principal
amount of the Debentures so redeemed shall be redeemed by the Trust at the
Redemption Price on a Pro Rata basis.

         "Tax Event" means that the Regular Trustees shall have received an
opinion of a nationally recognized independent tax counsel experienced in such
matters to the effect that, as a result of (a) any amendment to, or change
(including any announced prospective change) in, the laws (or any regulations
thereunder) of the United States or any political subdivision or taxing
authority thereof or therein or (b) any interpretation or application of, or
pronouncement with respect to, such laws or regulations by any legislative body,
court, governmental agency or regulatory authority (including the enactment of
any legislation and the publication of any judicial decision or regulatory
determination), which amendment or change is effective or which interpretation,
application or pronouncement is announced on or after the date of the Prospectus
Supplement, there is more than an insubstantial risk that (i) the Trust would be
subject to United States federal income tax with respect to interest accrued or
received on the Debentures, (ii) interest payable to the Trust on the Debentures
would not be deductible, in whole or in part, by the Debenture Issuer for United
States federal income tax purposes, or (iii) the Trust would be subject to more
than a de minimis amount of taxes, duties or other governmental charges.

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

         On and from the date fixed by the Regular Trustees for any distribution
of Debentures and dissolution of the Trust: (i) the Securities will no longer be
deemed to be outstanding, (ii) The Depository Trust Company (the "Depositary")
or its nominee (or any successor Clearing Agency or its nominee), as the record
Holder of the Preferred Securities, will receive a registered global certificate
or certificates representing the Debentures to be delivered upon such
distribution and any certificates representing Securities, except for
certificates representing Preferred Securities held by the Depositary or its
nominee (or any


                                      I - 5

   69
successor Clearing Agency or its nominee), will be deemed to represent
beneficial interests in the Debentures having an aggregate principal amount
equal to the aggregate stated liquidation amount of, with an interest rate
identical to the Coupon Rate of, and accrued and unpaid interest equal to
accrued and unpaid Distributions on such Securities until such certificates are
presented to the Debenture Issuer or its agent for transfer or reissue.

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

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

         (f)  "Redemption or Distribution Procedures."

              (i)       Notice of any redemption of, or notice of distribution 
         of Debentures in exchange for the Securities (a
         "Redemption/Distribution Notice") will be given by the Trust by mail to
         each Holder of Securities to be redeemed or exchanged not fewer than 30
         nor more than 60 days before the date fixed for redemption or exchange
         thereof which, in the case of a redemption, will be the date fixed for
         redemption of the Debentures. For purposes of the calculation of the
         date of redemption or exchange and the dates on which notices are
         given pursuant to this Section 4(f)(i), a Redemption/ Distribution
         Notice shall be deemed to be given on the day such notice is first
         mailed by first-class mail, postage prepaid, to Holders of Securities.
         Each Redemption/Distribution Notice shall be addressed to the Holders
         of Securities at the address of each such Holder appearing in the books
         and records of the Trust. No defect in the Redemption/Distribution
         Notice or in the mailing of either thereof with respect to any Holder
         shall affect the validity of the redemption or exchange proceedings
         with respect to any other Holder.

              (ii)      In the event that fewer than all the outstanding 
         Securities are to be redeemed, the Securities to be redeemed shall be
         redeemed Pro Rata from each Holder of Preferred Securities, it being
         understood that, in respect of Preferred Securities registered in the
         name of and held of record by the Depositary or its nominee (or any
         successor Clearing Agency or its nomi-



                                     I - 6


   70


         nee) or any nominee, the distribution of the proceeds of such
         redemption will be made to each Clearing Agency Participant (or Person
         on whose behalf such nominee holds such securities) in accordance with
         the procedures applied by such agency or nominee.

              (iii)     If Securities are to be redeemed and the Trust gives a
         Redemption/Distribution Notice, which notice may only be issued if the
         Debentures are redeemed as set out in this Section 4 (which notice
         will be irrevocable), then (A) while the Preferred Securities are in
         book-entry only form, with respect to the Preferred Securities, by
         12:00 noon, New York City time, on the redemption date, provided that
         the Debenture Issuer has paid the Institutional Trustee a sufficient
         amount of cash in connection with the related redemption or maturity of
         the Debentures, the Institutional Trustee will deposit irrevocably
         with the Depositary or its nominee (or successor Clearing Agency or
         its nominee) funds sufficient to pay the applicable Redemption Price
         with respect to the Preferred Securities and will give the Depositary
         irrevocable instructions and authority to pay the Redemption Price to
         the Holders of the Preferred Securities, and (B) with respect to
         Preferred Securities issued in definitive form and Common Securities,
         provided that the Debenture Issuer has paid the Institutional Trustee a
         sufficient amount of cash in connection with the related redemption or
         maturity of the Debentures, the Institutional Trustee will pay the
         relevant Redemption Price to the Holders of such Securities by check
         mailed to the address of the relevant Holder appearing on the books and
         records of the Trust on the redemption date. If a 
         Redemption/Distribution Notice shall have been given and funds 
         deposited as required, if applicable, then immediately prior to the
         close of business on the date of such deposit, or on the redemption
         date, as applicable, distributions will cease to accrue on the 
         Securities so called for redemption and all rights of Holders of such
         Securities so called for redemption will cease, except the right of the
         Holders of such Securities to receive the Redemption Price, but without
         interest on such Redemption Price. Neither the Regular Trustees nor the
         Trust shall be required to register or cause to be registered the
         transfer of any Securities that have been so called for redemption. If
         any date fixed for redemption of Securities 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


                                      I - 7

   71



         will be made on the immediately preceding Business Day, in each case
         with the same force and effect as if made on such date fixed for
         redemption. If payment of the Redemption Price in respect of any
         Securities is improperly withheld or refused and not paid either by
         the Institutional Trustee or by the Sponsor, as guarantor pursuant to
         the relevant Securities Guarantee, Distributions on such Securities
         will continue to accrue from the original redemption date to the actual
         date of payment, in which case the actual payment date will be
         considered the date fixed for redemption for purposes of calculating
         the Redemption Price.

              (iv)      Redemption/Distribution Notices shall be sent by the 
         Regular Trustees on behalf of the Trust to (A) in respect of the
         Preferred Securities, the Depository or its nominee (or any successor
         Clearing Agency or its nominee) if the Global Certificates have been
         issued or, if Definitive Preferred Security Certificates have been
         issued, to the Holder thereof, and (B) in respect of the Common
         Securities to the Holder thereof.

              (v)       Subject to the foregoing and applicable law (including,
         without limitation, United States federal securities laws), provided
         the acquiror is not the Holder of the Common Securities or the obligor
         under the Indenture, the Sponsor or any of its subsidiaries may at any
         time and from time to time purchase outstanding Preferred Securities by
         tender, in the open market or by private agreement.

         5.        Voting Rights - Preferred Securities.

         (a)  Except as provided under Sections 5(b) and 7 and as otherwise
required by law and the Declaration, the Holders of the Preferred Securities
will have no voting rights.

         (b)  Subject to the requirement of the Institutional Trustee obtaining
a tax opinion in certain circumstances set forth in the last sentence of this
paragraph, the Holders of a majority in aggregate liquidation amount of the
Preferred Securities, have the right to direct the time, method, and place of
conducting any proceeding for any remedy available to the Institutional
Trustee, or exercising any trust or power conferred upon the Institutional
Trustee under the Declaration, including (i) directing the time, method, place
of conducting any proceeding for any remedy available to the Debenture Trustee,
or exercising any trust or power conferred on the Debenture Trustee with
respect to the Debentures, (ii) waive any past default and its consequences that
is waivable under Section 513 of the Indenture,


                                      I - 8

   72
(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; provided, however, that, where a consent or action
under the Indenture would require the consent or act of the Holders of more than
a majority in principal amount of the Debentures (a "Super Majority") affected
thereby, the Institutional Trustee may only give such consent or take such
action at the written direction of the Holders of at least the proportion in
aggregate liquidation amount of the Preferred Securities which the relevant
Super Majority represents of the aggregate principal amount of the Debentures
outstanding. The Institutional Trustee shall not revoke any action previously
authorized or approved by a vote of the Holders of the Preferred Securities.
Other than with respect to directing the time, method and place of conducting
any remedy available to the Institutional Trustee or the Debenture Trustee as
set forth above, the Institutional Trustee shall not take any action in
accordance with the directions of the Holders of the Preferred Securities under
this paragraph unless the Institutional Trustee has obtained an opinion of tax
counsel to the effect that for the purposes of United States federal income tax
the Trust will not be classified as other than a grantor trust on account of
such action. If the Institutional Trustee fails to enforce its rights under the
Debentures (other than by reason of the failure to obtain the opinion set forth
in the last sentence of this paragraph), any Holder of Preferred Securities may,
to the fullest extent permitted by law, directly institute a legal proceeding
directly against the Company to enforce the Institutional Trustee's rights under
the Debentures without first instituting any legal proceeding against the
Institutional Trustee or any other Person or entity. The Institutional Trustee
shall notify all holders of the Preferred Securities of any notice of default
received from the Debenture Trustee with respect to the Debentures. Such notice
shall state that such Indenture Event of Default also constitutes a Declaration
Event of Default. Except with respect to directing the time, method and place of
conducting a proceeding for a remedy available to the Institutional Trustee, the
Institutional Trustee, as holder of the Debentures, shall not take any of the
actions described in clauses (i), (ii), (iii) or (iv) above unless the
Institutional Trustee has obtained an opinion of a nationally recognized
independent tax counsel experienced in such matters to the effect that, as a
result of such action, the Trust will not fail to be classified as a grantor
trust for United States federal income tax purposes. Notwithstanding the
foregoing, if a Declaration Event of Default has occurred and is continuing and
such event is attributable to the failure of the Debenture Issuer to pay
interest or principal on the Debentures on the date such interest or principal
is otherwise payable (or in the case of redemption, on the redemption date),
then a holder of Preferred Securities may directly institute a proceeding for
enforcement of payment to


                                      I - 9

   73
such Holder of the principal of or interest on the Debentures having a principal
amount equal to the aggregate liquidation amount of the Preferred Securities of
such holder on or after the respective due date specified in the Debentures.
Except as provided in the preceding sentence, the Holders of Preferred
Securities will not be able to exercise directly any other remedy available to
the holders of the Debentures.

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

         No vote or consent of the Holders of the Preferred Securities will be
required for the Trust to redeem and cancel Preferred Securities or to
distribute the Debentures in accordance with the Declaration and the terms of
the Securities.

         Notwithstanding that Holders of Preferred Securities are entitled to
vote or consent under any of the circumstances described above, any of the
Preferred Securities that are owned by the Sponsor or any Affiliate of the
Sponsor shall not be entitled to vote or consent and shall, for purposes of
such vote or consent, be treated as if they were not outstanding.

         6.        Voting Rights - Common Securities.

         (a)  Except as provided under Sections 6(b), (c) and as otherwise
required by law and the Declaration, the Holders of the Common Securities will
have no voting rights.

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

         (c)  Subject to Section 2.6 of the Declaration and only after the Event
of Default with respect to the Preferred Securities has been cured, waived, or
otherwise eliminated and subject to the requirements of the second to last
sentence of this paragraph, the Holders of a Majority in liquidation amount of
the


                                      I - 10


   74
Common Securities, voting separately as a class, may direct the time, method,
and place of conducting any proceeding for any remedy available to the
Institutional Trustee, or exercising any trust or power conferred upon the
Institutional Trustee under the Declaration, including (i) directing the time,
method, place of conducting any proceeding for any remedy available to the 
Debenture Trustee, or exercising any trust or power conferred on the Debenture
Trustee with respect to the Debentures, (ii) waive any past default and its
consequences that is waivable under Section 513 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; provided that, where a consent or action under the
Indenture would require the consent or act of the Holders of greater than a
majority in principal amount of Debentures (a "Super Majority") affected
thereby, the Institutional Trustee may only give such consent or take such
action at the written direction of the Holders of at least the proportion in
liquidation amount of the Common Securities which the relevant Super Majority
represents of the aggregate principal amount of the Debentures outstanding.
Pursuant to this Section 6(c), the Institutional Trustee shall not revoke any
action previously authorized or approved by a vote of the Holders of the
Preferred Securities. Other than with respect to directing the time, method and
place of conducting any remedy available to the Institutional Trustee or the
Debenture Trustee as set forth above, the Institutional Trustee shall not take
any action in accordance with the directions of the Holders of the Common 
Securities under this paragraph unless the Institutional Trustee has obtained an
opinion of tax counsel to the effect that for the purposes of United States
federal income tax the Trust will not be classified as other than a grantor
trust on account of such action. If the Institutional Trustee fails to enforce
its rights under the Debentures, any Holder of Common Securities may, to the
fullest extent permitted by law, institute a legal proceeding directly against
the Company to enforce the Institutional Trustee's rights under the Debentures,
without first instituting any legal proceeding against the Institutional Trustee
or any other Person.

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


                                     I - 11

   75
proposed for adoption at such meeting on which such Holders are entitled to vote
or of such matter upon which written consent is sought and (iii) instructions
for the delivery of proxies or consents.

         No vote or consent of the Holders of the Common Securities will be
required for the Trust to redeem and cancel Common Securities or to distribute
the Debentures in accordance with the Declaration and the terms of the
Securities.

         7.        Amendments to Declaration and Indenture.

         (a)  In addition to any requirements under Section 12.1 of the
Declaration, if any proposed amendment to the Declaration provides for, or the
Regular Trustees otherwise propose to effect, (i) any action that would
adversely affect the powers, preferences or special rights of the Securities,
whether by way of amendment to the Declaration or otherwise, or (ii) the 
dissolution, winding-up or termination of the Trust, other than as described in
Section 8.1 of the Declaration, then the Holders of outstanding Securities
voting together as a single 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
Securities affected thereby; provided, however, that, if any amendment or
proposal referred to in clause (i) above would adversely affect only the
Preferred Securities or only the Common Securities, then only the affected class
will be entitled to vote on such amendment or proposal and such amendment or
proposal shall not be effective except with the approval of a Majority in
liquidation amount of such class of Securities.

         Notwithstanding the foregoing, no amendment or modification may be
made to the Declaration if such amendment or modification would (i) cause the
Trust to be classified for United States federal income tax purposes as other
than a grantor trust, (ii) reduce or otherwise adversely affect the powers of
the Institutional Trustee or (iii) cause the Trust to be deemed an "investment
company" which is required to be registered under the 1940 Act.

         (b)  In the event the consent of the Institutional Trustee as the 
holder of the Debentures is required under the Indenture with respect to any
amendment, modification or termination of the Indenture, the Institutional
Trustee shall request the written direction of the Holders of the Securities
with respect to such amendment, modification or termination and shall vote with
respect to such amendment, modification or termination as directed by a Majority
in liquidation amount of the Securities voting together as a single class;
provided, however, that where any amendment, modification or termination of the
Indenture would require the consent of the holders of greater than a majority in


                                     I - 12

   76



aggregate principal amount of the Debentures (a "Super Majority"), the
Institutional Trustee may only give such consent at the direction of the Holders
of at least the proportion in liquidation amount of the Securities which the
relevant Super Majority represents of the aggregate principal amount of the
Debentures outstanding; provided, further, that the Institutional Trustee shall
not take any action in accordance with the directions of the Holders of the
Securities under this Section 7(b) unless the Institutional Trustee has obtained
an opinion of tax counsel to the effect that for the purposes of United States
federal income tax the Trust will not be classified as other than a grantor
trust on account of such action.


         8.        Pro Rata.

         A reference in these terms of the Securities to any payment,
distribution or treatment as being "Pro Rata" shall mean pro rata to each Holder
of Securities according to the aggregate liquidation amount of the Securities
held by the relevant Holder in relation to the aggregate liquidation amount of
all Securities outstanding unless, in relation to a payment, an Event of Default
under the Declaration 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.

         9.        Ranking.

         The Preferred Securities rank pari passu and payment thereon shall be
made Pro Rata with the Common Securities except that, where an Event of Default
occurs and is continuing under the Indenture in respect of the Debentures held
by the Institutional Trustee, the rights of Holders of the Common Securities to
payment in respect of Distributions and payments upon liquidation, redemption
and otherwise are subordinated to the rights to payment of the Holders of the
Preferred Securities.

         10.       Listing.

         The Regular Trustees shall use their best efforts to cause the
Preferred Securities to be listed for quotation on the New York Stock Exchange,
Inc.

         11.       Acceptance of Securities Guarantee and Indenture.


                                     I - 13

   77
         Each Holder of Preferred Securities and Common Securities, by the
acceptance thereof, agrees to the provisions of the Preferred Securities
Guarantee and the Common Securities Guarantee, respectively, including the
subordination provisions therein and to the provisions of the Indenture.

subscribe for any additional securities.

         13.       Miscellaneous.

         These terms constitute a part of the Declaration.

         The Sponsor will provide a copy of the Declaration, the Preferred
Securities Guarantee or the Common Securities Guarantee (as may be appropriate),

   80



                          [FORM OF REVERSE OF SECURITY]

         Distributions payable on each Preferred Security will be fixed at a
rate per annum of 8 5/8% (the "Coupon Rate") of the stated liquidation amount of
$25 per Preferred Security, such rate being the rate of interest payable on the
Debentures to be held by the Institutional Trustee. Distributions in arrears for
more than one quarter will bear interest thereon compounded quarterly at the
Coupon Rate (to the extent permitted by applicable law). The term
"Distributions" as used herein includes such cash distributions and any such
interest payable unless otherwise stated. A Distribution is payable only to the
extent that payments are made in respect of the Debentures held by the Inst-
itutional Trustee and to the extent the Institutional Trustee has funds
available therefor. The amount of Distributions payable for any period will be
computed for any full quarterly Distribution period on the basis of a 360-day
year of twelve 30-day months, and for any period shorter than a full quarterly
Distribution period for which Distributions are computed, Distributions will be
computed on the basis of the actual number of days elapsed per 30-day month.

         Except as otherwise described below, distributions on the Preferred
Securities will be cumulative, will accrue from the date of original issuance
and will be payable quarterly in arrears, on February 15, May 15, August 15,
and November 15 of each year, commencing on February 15, 1999, to Holders of
record fifteen (15) days prior to such payment dates, which payment dates shall
correspond to the interest payment dates on the Debentures. The Debenture Issuer
has the right under the Indenture to defer payments of interest by extending
the interest payment period from time to time on the Debentures for a period
not exceeding 20 consecutive quarters (each an "Extension Period") and, as a
consequence of such deferral, Distributions will also be deferred. Despite such
deferral, quarterly Distributions will continue to accrue with interest thereon
(to the extent permitted by applicable law) at the Coupon Rate compounded
quarterly during any such Extension Period. Prior to the termination of any such
Extension Period, the Debenture Issuer may further extend such Extension Period;
provided that such Extension Period together with all such previous and further
extensions thereof may not exceed 20 consecutive quarters. Payments of accrued
Distributions will be payable to Holders as they appear on the books and
records of the Trust on the first record date after the end of the Extension
Period. Upon the termination of any Extension Period and the payment of all
amounts then due, the Debenture Issuer may commence a new Extension Period,
subject to the above requirements.

         The Preferred Securities shall be redeemable as provided in the
Declaration.

                          [FORM OF REVERSE OF SECURITY]

         Distributions payable on each Common Security will be fixed at a rate
per annum of 8 5/8% (the "Coupon Rate") of the stated liquidation amount of $25
per Common Security, such rate being the rate of interest payable on the
Debentures to be held by the Institutional Trustee. Distributions in arrears for
more than one quarter will bear interest thereon compounded quarterly at the
Coupon Rate (to the extent permitted by applicable law). The term
"Distributions" as used herein includes such cash distributions and any such
interest payable unless otherwise stated. A Distribution is payable only to the
extent that payments are made in respect of the Debentures held by the Inst-
itutional Trustee and to the extent the Institutional Trustee has funds
available therefor. The amount of Distributions payable for any period will be
computed for any full quarterly Distribution period on the basis of a 360-day
year of twelve 30-day months, and for any period shorter than a full quarterly
Distribution period for which Distributions are computed, Distributions will be
computed on the basis of the actual number of days elapsed per 30-day month.

         Except as otherwise described below, distributions on the Common
Securities will be cumulative, will accrue from the date of original issuance
and will be payable quarterly in arrears, on February 15, May 15, August 15,
and November 15 of each year, commencing on February 15, 1999, to Holders of
record fifteen (15) days prior to such payment dates, which payment dates shall
correspond to the interest payment dates on the Debentures. The Debenture Issuer
has the right under the Indenture to defer payments of interest by extending
the interest payment period from time to time on the Debentures for a period
not exceeding 20 consecutive quarters (each an "Extension Period") and, as a
consequence of such deferral, Distributions will also be deferred. Despite such
deferral, quarterly Distributions will continue to accrue with interest thereon
(to the extent permitted by applicable law) at the Coupon Rate compounded
quarterly during any such Extension Period. Prior to the termination of any such
Extension Period, the Debenture Issuer may further extend such Extension Period;
provided that such Extension Period together with all such previous and further
extensions thereof may not exceed 20 consecutive quarters. Payments of accrued
Distributions will be payable to Holders as they appear on the books and
records of the Trust on the first record date after the end of the Extension
Period. Upon the termination of any Extension Period and the payment of all
amounts then due, the Debenture Issuer may commence a new Extension Period,
subject to the above requirements.

         The Common Securities shall be redeemable as provided in the
Declaration.

Indenture hereinafter referred to and is registered in the name of a Depositary
or a nominee of a Depositary. This Debenture is exchangeable for Debentures

Debenture issued is registered in the name of Cede & Co. or such other name as
requested by an authorized representative of The Depository Trust Company and
any payment hereon is made to Cede & Co., ANY TRANSFER, PLEDGE OR OTHER USE
HEREOF FOR VALUE OR OTHERWISE BY A PERSON IS WRONGFUL since the registered owner
hereof, Cede & Co., has an interest herein.

            8 5/8% JUNIOR SUBORDINATED DEFERRABLE INTEREST DEBENTURE
                              DUE NOVEMBER 15, 2038

         MCN ENERGY GROUP INC., a Michigan corporation (the "Company", which
term includes any successor corporation under the Indenture hereinafter referred
to), for value received, hereby promises to pay to the Institutional Trustee or
registered assigns, the principal sum of One Hundred Three Million Ninety-Two
Thousand Eight Hundred Dollars ($103,092,800) on November 15, 2038, and to pay
interest on said principal sum from November 18, 1998, or from the most recent
interest payment date (each such date, an "Interest Payment Date") to which
interest has been paid or duly provided for, quarterly (subject to deferral as
set forth herein) in arrears on February 15, May 15, August 15 and November 15
of each year commencing February 15, 1999, at the rate of 8 5/8% per annum until
the principal hereof shall have become due and payable, and on any overdue
principal and premium, if any, and (without duplication and to the extent that
payment of such interest is enforceable under applicable law) on any overdue
installment of interest at the same rate per annum compounded quarterly. The
amount of interest payable on any Interest Payment Date shall be computed on the
basis of a 360-day year of twelve 30-day months. In the event that any date on
which interest is payable on this Debenture is not a Business Day, then payment
of interest 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 is in the next succeeding calendar
year, such payment shall be made on the immediately preceding Business Day, in
each case with the same force and effect as if made on such date. The interest
installment so payable, and punctually paid or duly provided for, on any
Interest Payment Date will, as provided in the Indenture, be paid to the person
in whose name this Debenture (or one or more Predecessor Securities, as defined
in said Indenture) is registered at the close of business on the regular record
date for such interest installment, which shall be the close of business on the
business day next preceding such Interest Payment Date. Any such interest
installment not punctually paid or duly provided for shall forthwith cease to be
payable to the registered Holders on such regular

record date and may be paid to the Person in whose name this Debenture (or one
or more Predecessor Securities) is registered at the close of business on a
special record date to be fixed by the Trustee for the payment of such defaulted
interest, notice whereof shall be given to the registered Holders of this series
of Debentures not less than 10 days prior to such special record date, or may be
paid at any time in any other lawful manner not inconsistent with the
requirements of any securities exchange on which the Debentures may be listed,
and upon such notice as may be required by such exchange, all as more fully
provided in the Indenture. The principal of (and premium, if any) and the
interest on this Debenture shall be payable at the office or agency of the
Trustee maintained for that purpose in any coin or currency of the United States
of America that at the time of payment is legal tender for payment of public and
private debts; provided, however, that payment of interest may be made at the
option of the Company by check mailed to the registered Holder at such address
as shall appear in the Security Register. Notwithstanding the foregoing, so long
as the Holder of this Debenture is the Institutional Trustee, the payment of the
principal of (and premium, if any) and interest on this Debenture will be made
at such place and to such account as may be designated by the Institutional
Trustee.

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

         This Debenture shall not be entitled to any benefit under the Indenture
hereinafter referred to, be valid or become obligatory for any purpose until the
Certificate of Authentication hereon shall have been signed by or on behalf of
the Trustee.

         The provisions of this Debenture are continued on the reverse side
hereof and such continued provisions shall for all purposes have the same effect
as though fully set forth at this place.

                                 (REVERSE SIDE)

         This Debenture is one of a duly authorized series of Securities of the
Company (herein sometimes referred to as the "Securities"), specified in the
Indenture, all issued or to be issued in one or more series under and pursuant
to an Indenture dated as of September 1, 1994, duly executed and delivered
between the Company and NBD Bank, as Trustee (the "Trustee") (as supplemented
by a First Supplemental Indenture, dated April 17, 1996, a Second Supplemental
Indenture, dated as of July 24, 1996 and a Third Supplemental Indenture, dated
as of March 19, 1997, as so supplemented, the "Base Indenture"), as
supplemented by a Fourth Supplemental Indenture, dated as of November 18, 1998,
between the Company and the Trustee (the Base Indenture as so supplemented, the
"Indenture"), to which Indenture and all indentures supplemental thereto
reference is hereby made for a description of the rights, limitations of
rights, obligations, duties and immunities thereunder of the Trustee, the
Company and the Holders of the Securities. By the terms of the Indenture, the
Securities are issuable in series that may vary as to amount, date of maturity,
rate of interest and in other respects as provided in the Indenture. This
series of Securities is limited in aggregate principal amount as specified in
said Fourth Supplemental Indenture.

         Except as provided in the next paragraph, the Debentures may not be
redeemed by the Company prior to November 15, 2003. The Company shall have the
right to redeem this Debenture at the option of the Company, without premium or
penalty, in whole, at any time, or in part, from time to time, on or after
November 15, 2003 (an "Optional Redemption"), at a redemption price equal to
100% of the principal amount to be redeemed plus any accrued and unpaid
interest, including Additional Interest, if any, to the date of such redemption
(the "Optional Redemption Price"). Any redemption pursuant to this paragraph
will be made upon not less than 30 nor more than 60 days' notice, at the
Optional Redemption Price.

         If, at any time, a Special Event (as defined below) shall occur and be
continuing, the Company shall have the right upon not less than 30 nor more than
60 days' notice, to redeem the Debentures, in whole but not

                                       6
   93
in part, for cash at the Optional Redemption Price within 90 days following the
occurrence of such Special Event.

         "Tax Event" means that the Regular Trustees shall have received an
opinion of a nationally recognized independent tax counsel experienced in such
matters to the effect that, as a result of (a) any amendment to, or change
(including any announced prospective change) in the laws (or any regulations
thereunder) of the United States or any political subdivision or taxing
authority thereof or therein or (b) any interpretation or application of, or
pronouncement with respect to, such laws or regulations by any legislative body,
court, governmental agency or regulatory authority (including the enactment of
any legislation and the publication of any judicial decision or regulatory
determination), which amendment or change is effective or which interpretation,
application or pronouncement is announced on or after November 18, 1998, there
is more than an insubstantial risk that (i) the Trust would be subject to United
States federal income tax with respect to income accrued or received on the
Debentures, (ii) interest payable to the Trust on the Debentures would not be
deductible, in whole or in part, by the Company for United States federal income
tax purposes or (iii) the Trust would be subject to more than a de minimis
amount of other taxes, duties or other governmental charges.

         "Investment Company Event" means that the Regular Trustees shall have
received an opinion of a nationally recognized independent counsel experienced
in practicing under the 1940 Act, as amended (the "1940 Act") to the effect
that, as a result of the occurrence of a change in law or regulation or a
written change in interpretation or application of law or regulation by any
legislative body, court, governmental agency or regulatory authority (a "Change
in 1940 Act Law"), there is more than an insubstantial risk that the Trust is or
will be considered an "investment company" which is required to be registered
under the 1940 Act, which Change in 1940 Act Law becomes effective on or after
November 13, 1998.

         Any redemption pursuant to the occurrence of a Tax Event or an
Investment Company Event (each as defined above a "Special Event") will be made
upon not less than 30 days nor more than 60 days notice, at the Optional
Redemption Price. If the Debentures are only partially re-

                                        7
   94
deemed by the Company pursuant to an Optional Redemption, the Debentures will be
redeemed pro rata or by lot or by any other method utilized by the Trustee;
provided that if, at the time of redemption, the Debentures are registered as a
Global Debenture, the Depositary shall determine the principal amount of such
Debentures held by each Debentureholder to be redeemed in accordance with its
procedures.

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

         In case an Event of Default, as defined in the Indenture, shall have
occurred and be continuing, the principal of all of the Debentures may be
declared, and upon such declaration shall become, due and payable, in the
manner, with the effect and subject to the conditions provided in the Indenture.

         The Indenture contains provisions permitting the Company and the
Trustee, with the consent of the Holders of not less than a majority in
aggregate principal amount of the Debentures of each series affected at the time
outstanding, as defined in the Indenture, to execute supplemental indentures for
the purpose of adding any provisions to or changing in any manner or eliminating
any of the provisions of the Indenture or of any supplemental indenture or of
modifying in any manner the rights of the Holders of the Debentures; provided,
however, that no such supplemental indenture shall (i) reduce the principal
amount thereof, or reduce the rate or extend the time of payment of interest
thereon, or reduce any premium payable upon the redemption thereof, without the
consent of the Holder of each Debenture so affected, or (ii) reduce the
aforesaid percentage of Debentures, the Holders of which are required to consent
to any such supplemental indenture, without the consent of the Holders of each
Debenture then outstanding and affected thereby. The Indenture also contains
provisions permitting the Holders of a majority in aggregate principal amount of
the Securities of any series at the time outstanding affected thereby, on behalf
of all of the Holders of the Debentures of such series, to waive Default or
Event of Default with respect to such series, and its consequences, except a
Default or Event of Default in the


                                       8

   95




payment of the principal of or premium, if any, or interest on any of the
Securities of such series. Any such consent or waiver by the registered Holder
of this Debenture (unless revoked as provided in the Indenture) shall be
conclusive and binding upon such Holder and upon all future Holders and owners
of this Debenture and of any Debenture issued in exchange herefor or in place
hereof (whether by registration of transfer or otherwise), irrespective of
whether or not any notation of such consent or waiver is made upon this
Debenture.

         No reference herein to the Indenture and no provision of this Debenture
or of the Indenture shall alter or impair the obligation of the Company, which
is absolute and unconditional, to pay the principal of and premium, if any, and
interest on this Debenture at the time and place and at the rate and in the
money herein prescribed.

         So long as the Company is not in default in the payment of interest on
the Debentures, the Company shall have the right at any time during the term of
the Debentures from time to time to extend the interest payment period of such
Debentures for up to 20 consecutive quarters (an "Extended Interest Payment
Period"), at the end of which period the Company shall pay all interest then
accrued and unpaid (together with the interest thereon at the rate specified for
the Debentures to the extent that payment of such interest is enforceable under
applicable law). In the event that the Company exercises this right, then (a)
the Company shall not declare or pay dividends on, make any distributions with
respect to, or redeem, purchase or acquire, or make a liquidation payment with
respect to, any of its capital stock (other than (i) repurchases, redemptions or
other acquisitions of shares of its Common Stock in connection with any
employment contract, benefit plan or other similar arrangement with or for the
benefit of employees, officers, directors or consultants (ii) as a result of an
exchange or conversion of any class or series of the Company's capital stock,
(iii) the purchase of fractional interests in shares of the Company's capital
stock pursuant to the conversion or exchange provisions of such capital stock or
the security being converted or exchanged or (iv) distributions of rights under
any shareholder rights plan adopted by the Company) (b) the Company shall not
make any payment of interest, principal or premium, if any, on


                                       9


   96




or repay, repurchase or redeem any debt securities issued by the Company or its
subsidiaries that rank pari passu with or junior to such Debentures and (c) the
Company shall not make any guarantee payments with respect to the foregoing
(other than pursuant to the Preferred Securities Guarantee). The foregoing,
however, will not apply to any stock dividend paid by the Company where the
dividend stock is the same stock as that on which the dividend is being paid.
Prior to the termination of any such Extended Interest Payment Period, the
Company may further extend the interest payment period; provided, that such
Extended Interest Payment Period, together with all such previous and further
extensions thereof, may not exceed 20 consecutive quarters or extend beyond the
maturity date of the Debenture. At the termination of any such Extended Interest
Payment Period and upon the payment of all accrued and unpaid interest and any
additional amount then due, the Company may commence a new Extended Interest
Payment Period, subject to the above requirements.

         As provided in the Indenture and subject certain limitations therein
set forth, this Debenture is transferable by the registered Holder hereof on the
Security Register of the Company, upon surrender of this Debenture for
registration of transfer at the office or agency of the Trustee in the City of
Detroit and State of Michigan accompanied by a written instrument or instruments
of transfer in form satisfactory to the Company or the Trustee duly executed by
the registered Holder hereof or his attorney duly authorized in writing, and
thereupon one or more new Debentures of authorized denominations and for the
same aggregate principal amount and series will be issued to the designated
transferee or transferees. No service charge will be made for any such transfer,
but the Company may require payment of a sum sufficient to cover any tax or
other governmental charge payable in relation thereto.

         Prior to due presentment for registration of transfer of this
Debenture, the Company, the Trustee, any paying agent and the Security Registrar
may deem and treat the registered holder hereof as the absolute owner hereof
(whether or not this Debenture shall be overdue and notwithstanding any notice
of ownership or writing hereon made by anyone other than the Security Registrar)
for the purpose of receiving payment of or on account of



                                       10
   97




the principal hereof and premium, if any, and interest due hereon and for all
other purposes, and neither the Company nor the Trustee nor any paying agent nor
any Security Registrar shall be affected by any notice to the contrary.

         No recourse shall be had for the payment of the principal of or the
interest on this Debenture, or for any claim based hereon, or otherwise in
respect hereof, or based on or in respect of the Indenture, against any
incorporator, stockholder, officer or director, past, present or future, as
such, of the Company or of any predecessor or successor corporation, whether by
virtue of any constitution, statute or rule of law, or by the enforcement of any
assessment or penalty or otherwise, all such liability being, by the acceptance
hereof and as part of the consideration for the issuance hereof, expressly
waived and released.

         The Indenture imposes certain limitations on the ability of the Company
to, among other things, merge or consolidate with any other Person or sell,
assign, transfer or lease all or substantially all of its properties or assets.
All such covenants and limitations are subject to a number of important
qualifications and exceptions. The Company must report periodically to the
Trustee on compliance with the covenants in the Indenture.

         The Debentures of this series are issuable only in registered form
without coupons in denominations of $25 and any integral multiple thereof. This
Global Debenture is exchangeable for Debentures in definitive form only under
certain limited circumstances set forth in the Indenture. Debentures of this
series so issued are issuable only in registered form without coupons in
denominations of $25 and any integral multiple thereof. As provided in the
Indenture and subject to certain limitations therein set forth, Debentures of
this series so issued are exchangeable for a like aggregate principal amount of
Debentures of this series of a different authorized denomination, as requested
by the Holder surrendering the same.

         All terms used in this Debenture that are defined in the Indenture
shall have the meanings assigned to them in the Indenture.
