         SECTION 2.6.  EVENTS OF DEFAULT; WAIVER.

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

                           (i) is not waivable under the Indenture, the Event of
                  Default under the 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 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 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


                                       9

<Page>

                  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 aggregate liquidation amount of the Common Securities that
                  the relevant Super Majority represents of the aggregate
                  principal amount of the Debentures outstanding;

         PROVIDED FURTHER, that each Holder of Common Securities will be deemed
         to have waived any such Event of Default and all Events of Default with
         respect to the Common Securities and its consequences until all Events
         of Default with respect to the Preferred Securities have been cured,
         waived or otherwise eliminated, and until such Events of Default have
         been so cured, waived or otherwise eliminated, the Institutional
         Trustee will be deemed with respect to the Preferred Securities to be
         acting solely on behalf of the Holders of the Preferred Securities and
         only the Holders of the Preferred Securities will have the right to
         direct the 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 written direction of the Holders of the
         Preferred Securities constitutes a waiver of the corresponding Event of
         Default with respect to the Preferred Securities under this
         Declaration. Any waiver of an Event of Default under the Indenture by
         the Institutional Trustee at the direction of the Holders of the
         Preferred Securities shall also be deemed to constitute a waiver by the
         Holders of the Common Securities of the corresponding Event of Default
         under this Declaration with respect to the Common Securities for all
         purposes of this Declaration without further act, vote or consent of
         the Holders of the Common Securities. The foregoing provisions of this
         Section 2.6(c) 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.

                  (a) The Institutional Trustee shall, within 90 days after a
         Responsible Officer of the Institutional Trustee obtains actual
         knowledge of 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 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 with respect to 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 or Event of Default under Sections 5.1
                  or 5.3 of the Indenture; or

                           (ii) any default or Event of 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

                  Debenture Issuer for United States federal income tax
                  purposes,

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

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

         information reports that are required to be filed with respect to the
         Trust to be duly prepared and filed by the Regular Trustees, on
         behalf of the Trust; and

                  (q) to execute all documents or instruments, perform all
         duties and powers, and do all things for and on behalf of the Trust in
         all matters necessary or incidental to the foregoing.

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

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

         Any expenses incurred by the Regular Trustees pursuant to this Section
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 Trustee) shall not, engage in any activity other than as
         required or authorized by this Declaration. In particular, the Trust
         shall not and the Trustees (including the Institutional Trustee) shall
         cause the Trust not to:

                           (i) invest any proceeds received by the Trust from
                  holding the Debentures, but shall distribute all such proceeds
                  to Holders of Securities pursuant to the terms of this
                  Declaration and of the Securities;

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

                           (iii) possess Trust property for other than a Trust
                  purpose as set forth in Section 3.3;

                           (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 way whatsoever;

                           (vi) issue any securities or other evidences of
                  beneficial ownership of, or beneficial interest in, the Trust
                  other than the Securities; or

                           (vii) other than as provided in this Declaration
                  (including, without


                                      15

<Page>

                  limitation, Annex I), (A) direct the time, method and place
                  of conducting any proceeding with respect to any remedy
                  available to the Debenture Trustee or exercising any trust
                  or power conferred upon the Debenture Trustee with respect
                  to the Debentures, (B) waive any past default under the
                  Indenture, (C) exercise any right to rescind or annul any
                  declaration that the principal of all the Debentures shall
                  be due and payable, or (D) consent to 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 nationally
                  recognized tax counsel to the effect that such amendment,
                  modification or termination will not cause more than an
                  insubstantial risk that for United States federal income
                  tax purposes the Trust will be classified as other than a
                  grantor trust as a result of such action.

         SECTION 3.8.  POWERS AND DUTIES OF THE INSTITUTIONAL TRUSTEE.

                  (a) The legal title to the Debentures shall be held by the
         Institutional Trustee in trust for the benefit of the Holders of the
         Securities. The right, title and interest of the Institutional 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 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


                                       16


<Page>

                  appropriate to effect the redemption of the Preferred
                  Securities and the Common Securities pursuant to this
                  Declaration (including, without limitation, Annex I) 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 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 (as defined in
                  Section 5.6) 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
         Debentures 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 or waiving 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 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


                                      18


<Page>

                  the Holders of not less than a Majority in 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 in writing 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.

         SECTION 3.10.  CERTAIN RIGHTS OF INSTITUTIONAL TRUSTEE.

                  (a)  Subject to the provisions of Section 3.9:

                           (i) the Institutional Trustee may conclusively rely
                  and shall be fully protected in acting or refraining from

                  instrument, opinion, report, notice, request, direction,
                  consent, order,


                                      19

                  parties;

                           (ii) any direction or act of the Sponsor or the
                  Regular Trustees contemplated by this Declaration shall be
                  sufficiently evidenced by a Direction or an Officers'
                  Certificate;

                           (iii) whenever, in the administration of this
                  Declaration, the Institutional Trustee shall deem it desirable
                  that a matter be proved or established before taking,
                  suffering or omitting any action hereunder, the Institutional
                  Trustee (unless other evidence is herein specifically
                  prescribed) may, in the absence of bad faith on its part,
                  request and conclusively rely upon an Officers' Certificate
                  which, upon receipt of such request, shall be promptly
                  delivered by the Sponsor or the Regular Trustees;

                           (iv) the Institutional Trustee shall have no duty to
                  see to any recording, filing or registration of any instrument
                  (including any financing or continuation statement or any
                  filing under tax or securities laws) or any rerecording,
                  refiling or reregistration thereof;

                           (v) the Institutional Trustee may consult with
                  counsel or other experts and the advice or opinion of such
                  counsel and experts with respect to legal matters or advice
                  within the scope of such experts' area of expertise shall be
                  full and complete authorization and protection in respect of
                  any action taken, suffered or omitted by it hereunder in good
                  faith and in accordance with such advice or opinion, it being
                  understood that such counsel may be counsel to the Sponsor or
                  any of its Affiliates, and may include any of its employees.
                  The Institutional Trustee shall have the right at any time to

                  obligation to exercise any of the rights or powers vested in
                  it by this Declaration at the request or direction of any
                  Holder, unless such Holder shall have provided to the
                  Institutional Trustee security and indemnity, reasonably
                  satisfactory to the Institutional Trustee, against the costs,

                  expenses of the Institutional Trustee's agents, nominees or
                  custodians) and liabilities that might be incurred by it in

                  reasonable advances as may be requested by the Institutional
                  Trustee provided, that, nothing contained in this Section
                  3.10(a)(vi) shall be taken to relieve the Institutional
                  Trustee, upon the occurrence of an Event of Default, of its
                  obligation to exercise the rights and powers vested in it by

                  discretion, may make such further inquiry or investigation
                  into such facts or matters as it may see fit;

                           (viii) the Institutional Trustee may execute any of
                  the trusts or powers hereunder or perform any duties hereunder
                  either directly or by or through agents, custodians, nominees
                  or attorneys and the Institutional Trustee shall not be
                  responsible for any misconduct or negligence on the part of

                           (ix) any action taken by the Institutional Trustee or
                  its agents hereunder shall bind the Trust and the Holders of
                  the Securities, and the signature of the Institutional Trustee
                  or its agents alone shall be sufficient and effective to
                  perform any such action and no third party shall be required
                  to inquire as to the authority of the Institutional Trustee to
                  so act or as to its compliance with any of the terms and
                  provisions of this Declaration, both of which shall be
                  conclusively evidenced by the Institutional Trustee's or its
                  agent's taking such action;

                           (x) whenever in the administration of this
                  Declaration the Institutional Trustee shall deem it desirable
                  to receive instructions with respect to enforcing any remedy
                  or right or taking any other action hereunder, the
                  Institutional Trustee (i) may request instructions from the
                  Holders of the Securities which instructions may only be given
                  by the Holders of the same proportion in liquidation amount of
                  the Securities as would be entitled to direct the
                  Institutional Trustee under the terms of the Securities in
                  respect of such remedy, right or action, (ii) may refrain from
                  enforcing such remedy or right or taking such other action
                  until such instructions are received, and (iii) shall be fully
                  protected in conclusively relying on or acting in accordance
                  with such instructions; and

                           (xi) except as otherwise expressly provided by this
                  Declaration, the Institutional Trustee shall not be under any
                  obligation to take any action that is discretionary under the
                  provisions of this Declaration.

                           (xii) the Institutional Trustee shall not be liable
                  for any action taken, suffered, or omitted to be taken by it
                  in good faith, without negligence, and reasonably believed by
                  it to be authorized or within the discretion or rights or
                  powers conferred upon it by this Declaration;

                           (xiii) when the Institutional Trustee incurs expenses
                  or renders services in connection with an Event of Default
                  under the Indenture, such expenses (including the fees and
                  expenses of its counsel) and the compensation for such
                  services are intended to constitute expenses of administration
                  under any bankruptcy law or law relating to creditors rights
                  generally;

                           (xiv) in no event shall the Institutional Trustee be
                  liable for the selection of investments or for investment
                  losses incurred thereon. The Institutional Trustee shall have
                  no liability in respect of losses incurred as a result of the
                  liquidation of any such investment prior to its stated
                  maturity or the failure of the party directing such investment
                  to provide timely written investment direction. The
                  Institutional Trustee shall have no obligation to invest or
                  reinvest any amounts held hereunder in the absence of such
                  written investment direction; and

                           (xv) in the event that the Institutional Trustee is
                  also acting as Paying Agent hereunder, the rights and
                  protections afforded to the Institutional Trustee pursuant to
                  this Article III shall also be afforded to such Paying Agent.

                  (b) No provision of this Declaration shall be deemed to impose
         any duty or obligation on the Institutional Trustee to perform any act
         or acts or exercise any right, power, duty or obligation conferred or
         imposed on it, in any jurisdiction in which it shall be illegal, or in
         which the Institutional Trustee shall be unqualified or incompetent in
         accordance with applicable law, to perform any such act or acts, or to
         exercise any such right, power, duty or obligation. No permissive power
         or authority available to the Institutional Trustee shall be construed
         to be a duty.

         SECTION 3.11. DELAWARE TRUSTEE. Notwithstanding any other provision of
this Declaration other than Section 5.2, the Delaware Trustee shall not be
entitled to exercise any powers, nor shall the Delaware Trustee have any of the

Trustee shall be a Trustee for the sole and limited purpose of fulfilling the

Act. In the event that the Delaware Trustee is required to take any action or
perform any duty hereunder, the Delaware Trustee shall be entitled to the
benefits of Section 3.9(b)(ii) through (viii) and Section 3.10 of this
Declaration.

         SECTION 3.12. EXECUTION OF DOCUMENTS. Unless otherwise determined by
the Regular Trustees, and except as otherwise required by the Business Trust
Act, any Regular Trustee is authorized to execute on behalf of the Trust any

in Section 3.6(b)(i), including any amendments thereto, shall be signed by all
of the Regular Trustees.

         SECTION 3.13. NOT RESPONSIBLE FOR RECITALS OR ISSUANCE OF SECURITIES.
The recitals contained in this Declaration and the Securities shall be taken as
the statements of the Sponsor, and the Trustees do not assume any responsibility

condition of the property of the Trust or any part thereof. The Trustees make no
representations as to the validity or sufficiency of this Declaration or the
Securities.

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

                  (b) The Trust may, with the consent of the Regular Trustees
         (or, if there are more than two, a majority of the Regular Trustees)
         and without the consent of the Holders of the Securities, the Delaware
         Trustee or the Institutional Trustee, 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 Preferred Securities
                           other securities having substantially the same terms
                           as the Preferred Securities (the "Successor
                           Securities") so long as the Successor Securities rank
                           the same as the Preferred Securities rank with
                           respect to Distributions and payments upon
                           liquidation, redemption and otherwise;

                           (ii) the Debenture Issuer expressly appoints a
                  trustee of the Successor Entity that possesses 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 any Successor Securities will be
                  listed upon notification of issuance, on any national
                  securities exchange or with another organization on which the
                  Preferred Securities are then listed or quoted;

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

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


                                      23

                  as a result of such merger, consolidation, amalgamation or
                  replacement);

                           (vi) such Successor Entity has a purpose 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);
                           and

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

                                    (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 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.

         eligible to so act under Section 5.3(a), the Institutional Trustee
         shall immediately resign in the manner and with the effect set forth in

                  (a) Subject to Section 5.6(b), Trustees may be appointed or
         removed without cause at any time:

                           (i) until the issuance of any Securities, by written
                  instrument executed by the Sponsor; and

                  the Holders of a Majority in liquidation amount of the Common
                  Securities voting as a class at a meeting of the Holders of
                  the Common Securities.

                  (b) (i) The Trustee that acts as Institutional Trustee shall
                  not be removed in accordance with Section 5.6(a) until a
                  Successor Institutional Trustee (a "Successor Institutional
                  Trustee") has been appointed and has accepted such appointment
                  by written 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 Sections 5.2 and 5.4 (a "Successor

                  Delaware Trustee and delivered to the Regular Trustees and the

                  (c) A Trustee appointed to office shall hold office until his
         successor shall have been appointed or until his death, removal or
         resignation. Any Trustee may resign from office (without need for prior
         or subsequent accounting) by an instrument in writing signed by such
         Trustee and delivered to the Sponsor and the Trust, which resignation
         shall take effect upon such delivery or upon such later date as is
         specified therein; provided, however, that:

                           (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 liquidated and the proceeds thereof
                           distributed to the holders of the Securities; and

                           (ii) no such resignation of the Trustee that acts as
                  the Delaware Trustee shall be effective until a Successor
                  Delaware Trustee has been appointed and has accepted such
                  appointment by instrument executed by such Successor Delaware


                                      28

<Page>

                  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 Section 5.6 within 60 days after delivery to the
         Sponsor and the Trust of an instrument of resignation, the resigning
         Institutional Trustee or Delaware Trustee, as applicable, may petition
         any court of competent jurisdiction for appointment of a Successor
         Institutional Trustee or Successor Delaware Trustee. Such court may
         thereupon, after prescribing such notice, if any, as it may deem proper
         and prescribe, appoint a Successor Institutional Trustee or Successor
         Delaware Trustee, as the case may be.

                  (f) No Institutional Trustee or Delaware Trustee shall be
         liable for the acts or omissions to act of any Successor Institutional
         Trustee or Successor Delaware Trustee, as the case may be.

         SECTION 5.7. VACANCIES AMONG TRUSTEES. If a Trustee ceases to hold
office for any reason and the number of Trustees is not reduced pursuant to
Section 5.1, or if the number of Trustees is 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. Any
such 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, regardless of their number, shall have all the
powers granted to the Regular Trustees and shall discharge all the duties
imposed upon the Regular Trustees by this Declaration.

         SECTION 5.9. MEETINGS. If there is more than one Regular Trustee,
meetings of the Regular Trustees shall be held from time to time upon the
call of any Regular Trustee. Regular meetings of the Regular Trustees may be
held at a time and place fixed by resolution of the Regular Trustees. Notice
of any in-person meetings of the Regular Trustees shall be hand delivered or
otherwise delivered in writing (including by facsimile, with a hard copy by
overnight courier) not less than 48 hours before such meeting. Notice of any
telephonic meetings of the Regular Trustees or any committee thereof shall be
hand delivered or otherwise delivered in writing (including by facsimile,
with a hard copy by overnight courier) not less than


                                      29

<Page>

24 hours before such meeting. Notices shall contain a brief statement of 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 lawfully 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.

         SECTION 5.10.  DELEGATION OF POWER.

                  (a) Any Regular Trustee may, by power of attorney consistent
         with applicable law, delegate to any other natural person over the age
         of 21 his or her power for the purpose of executing any documents
         contemplated in Section 3.6, including any registration statement or
         amendment thereto filed with the Commission, or making any other
         governmental filing; and

                  (b) the Regular Trustees shall have power to delegate from
         time to time 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.

         SECTION 5.11. MERGER, CONVERSION, CONSOLIDATION OR SUCCESSION TO
BUSINESS. Any Person into which the Institutional Trustee or the Delaware
Trustee, as the case may be, may be merged or converted or with which either may
be consolidated, or any Person 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 Person succeeding to all or substantially
all the corporate trust business of the Institutional Trustee or the Delaware
Trustee, as the case may be, shall be the successor of the Institutional Trustee
or the Delaware Trustee, as the case may be, hereunder, provided such Person
shall be otherwise qualified and eligible under this Article, without the
execution or filing of any paper or any further act on the part of any of the
parties hereto.


                                   ARTICLE VI.

                                  DISTRIBUTIONS

         SECTION 6.1. DISTRIBUTIONS. Holders shall receive Distributions (as
defined herein) in accordance with the applicable terms of the relevant Holder's
Securities. Distributions shall be

made on the Preferred Securities and the Common Securities in accordance with
the preferences set forth in their respective terms. If and to the extent
that the Debenture Issuer makes a payment of interest (including Compounded
Interest (as defined in the Indenture) and Additional Interest (as 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 such Payment Amount to Holders.

                                  ARTICLE VII.

                             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"), which terms are incorporated
         by reference in, and made a part of, this Declaration as if
         specifically set forth herein, 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"), which terms are incorporated by reference in, and made a
         part of, this Declaration as if specifically set forth herein. The
         Trust shall issue no securities or other interests in the assets of the
         Trust other than the Preferred Securities and the Common Securities.

                  (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
         Certificate, 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 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 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 (subject to Section 10.1) 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

<Page>

         Declaration and the Preferred Securities Guarantee.

         SECTION 7.2. PAYING AGENT. In the event that the Preferred Securities
are not in book-entry only form, the Trust shall maintain 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 such 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. 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 Institutional Trustee
shall initially act as Paying Agent for the Preferred Securities and the Common
Securities.

                                  ARTICLE VIII.

                              TERMINATION OF TRUST

         SECTION 8.1. TERMINATION OF TRUST. (a) The Trust shall dissolve in the
earlier to occur of 55 years after the issuance of the Debentures or:

                           (i)  upon the bankruptcy of the Sponsor;

                           (ii) upon the filing of a certificate of dissolution
                  or its equivalent with respect to the Sponsor or the
                  revocation of the Sponsor's charter and the expiration of 90
                  days after the date of revocation without a reinstatement
                  thereof;

                           (iii) upon the consent of a Majority in liquidation
                  amount of the Securities affected thereby voting together as a
                  single class to dissolve the Trust;

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

                           (v) 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 each case in
                  accordance with the terms of the Securities;

                           (vi) at the election of the Sponsor (which is wholly
                  within its sole discretion) at any time pursuant to which the
                  Trust shall have been dissolved in accordance with the terms
                  of the Securities as set forth in Annex I and all of the
                  Debentures endorsed thereon shall have been distributed to the
                  Holders of Securities in exchange for all of the Securities;
                  or

                           (vii) before the issuance of any Securities, with the
                  consent of all of the


<Page>

                  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 satisfaction of all liabilities of the Trust in
         accordance with the Business Trust Act, the Trustees shall file a
         certificate of cancellation with the Secretary of State of the State of
         Delaware and the Trust shall terminate.

                  (c) The provisions of 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

         the condition precedent that the transferor obtain the written opinion
         of nationally recognized independent counsel experienced in such

         risk that:

                           (i) the Trust would not continue to 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 Certificate shall
be entitled

<Page>

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

                  (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 the Clearing Agency shall 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

<Page>

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:

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

                           (ii) upon surrender of the Global Certificate(s) by
                  the Clearing Agency, accompanied by registration instructions,
                  the Regular Trustees shall cause Definitive Preferred Security
                  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


<Page>

         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.

                                   ARTICLE X.

                           LIMITATION OF LIABILITY OF

                    HOLDERS OF SECURITIES, TRUSTEES OR OTHERS

         SECTION 10.1.  LIABILITY.

                  (a) Except as expressly set forth in this Declaration, the
         Debentures, the Preferred Securities Guarantee, the Common Securities
         Guarantee 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; or

                           (ii) 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.


<Page>

                  (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 performed
         or omission made 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 ordinary negligence
         in the case of the Institutional Trustee) or willful misconduct with
         respect to such acts or omissions.

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


<Page>

         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:

                           (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


<Page>


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

                           (iii) To the extent that a Company Indemnified Person
                  shall be successful on the merits or otherwise (including
                  dismissal of an action without prejudice or the settlement of
                  an action without admission of liability) in defense of any
                  action, suit or proceeding referred to in paragraphs (i) and
                  (ii) of this Section 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 Sponsor 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
                  Debenture 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

<Page>

                  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

<Page>

                  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 Sponsor agrees to indemnify (I) the 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 gross negligence (or, in the case of the
         Institutional Trustee, pursuant to Section 3.9, negligence) or bad
         faith on its part, arising out of or in connection with the acceptance
         or administration of 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 resignation or removal of the
         Institutional Trustee or the Delaware Trustee and the satisfaction and
         discharge of this Declaration.

                  (c) The Sponsor agrees to pay the Institutional Trustee and
         the Delaware Trustee, from time to time, such compensation for all
         services rendered by the Institutional Trustee and the Delaware Trustee
         hereunder including reasonable compensation expenses and disbursements
         of its agents and counsel as may be mutually agreed upon in writing by
         the Sponsor and the Institutional Trustee or the Delaware Trustee, as
         the case may be, and, except as otherwise expressly provided herein, to
         reimburse the Institutional Trustee and the Delaware trustee upon its
         or their request for all reasonable expenses, disbursements and
         advances incurred or made by the Institutional Trustee or the Delaware
         Trustee, as the case may be, in accordance with the provisions of this
         Trust Agreement, except any such expense, disbursement or advance as
         may be attributable to its or their negligence or bad faith.

         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
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
Persons, 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


<Page>

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.

                                   ARTICLE XI.

                                   ACCOUNTING

         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 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. The
         Regular Trustees shall endeavor to deliver all such statements within
         30 days after the end of each Fiscal Year of the Trust.

                  (c) 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


<Page>

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 or beneficial owner, 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 or beneficial owner, shall remit amounts withheld with respect to
the Holder or beneficial owner 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 or beneficial owner, the
amount withheld shall be deemed to be a Distribution in the amount of the
withholding to the Holder or beneficial owner. In the event of any claimed over
withholding, Holders shall be limited to an action against the applicable
jurisdiction. If the amount required to be withheld was not withheld from actual
Distributions made, the Trust may reduce subsequent Distributions by the amount
of such withholding.

                                  ARTICLE XII.

                           (i) unless, in the case of any proposed amendment,
                  the Institutional Trustee shall have first received an
                  Officers' Certificate from each of the Trust and the Sponsor

                           be classified for purposes of United States federal
                           income taxation as a grantor trust;

                                    (B) reduce or otherwise adversely affect the
                           powers of the Institutional Trustee in contravention
                           of the Trust Indenture Act; or

                                    (C) cause the Trust to be deemed to be an
                           Investment Company required to be registered under
                           the Investment Company Act;

                  (c) at such time after the Trust has issued any Securities
         that remain outstanding, any amendment that would adversely affect the
         rights, privileges or preferences of any Holder of Securities may be
         effected only with such additional requirements as may be set forth in
         the terms of such Securities;

                  (d) Section 9.1(c), Section 10.1(c) and this Section 12.1

                           (v) modify, eliminate and add to any provision of

         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 evidenced by Securities Certificates so 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 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


<Page>

                  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.

                                  ARTICLE XIII.

                                     ANNEX I

                                    TERMS OF
                  7-1/2% TRUST ORIGINATED PREFERRED SECURITIES
                    7-1/2% TRUST ORIGINATED COMMON SECURITIES

         Pursuant to Section 7.1 of the Amended and Restated Declaration of
Trust, dated as of August 22, 2001 (as amended from time to time, the
"Declaration"), the designation, rights, privileges, restrictions, preferences
and other terms and provisions of the Preferred Securities and the Common
Securities are set out below (each capitalized term used but not defined herein
has the meaning set forth in the Declaration or, if not defined in such
Declaration, as defined in the Prospectus Supplement referred to below or the
Prospectus, dated July 13, 1999, which it supplements):

         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 "7-1/2% Trust Originated Preferred Securities(sm) (`TOPrS(sm)')" (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. 123,720 Common Securities of the Trust
with an aggregate liquidation amount with respect to the assets of the Trust of
three million ninety three thousand dollars ($3,093,000) 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 "7-1/2% Trust
Originated Common Securities" (the "Common 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. (a) Distributions payable on each Security will be
fixed at a rate per annum of 7-1/2% (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 three consecutive months 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

<Page>



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 90-day quarter.

                  (b) Distributions on the Securities will be cumulative, will
accrue from August 22, 2001, and will be payable quarterly in arrears, on
February 15, May 15, August 15 and November 15 of each year, commencing on
November 15, 2001, 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 such period, 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 any such deferral, Distributions
will also be deferred. Despite any 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. Upon the termination of any Extension Period, payments of
accrued Distributions will be payable to Holders as they appeared on the books
and records of the Trust on the record date immediately preceding the end of the
applicable 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 dates shall be one Business Day prior to the relevant
payment dates, which payment dates shall 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
Securities -- Certain terms of the trust preferred securities -- Book-entry only
issuance -- DTC" in the Prospectus Supplement dated August 17, 2001, of the
Trust included in the Registration Statement on Form S-3 of the Sponsor and the
Trust. The relevant record dates for the Common Securities shall be the same
record dates as for the Preferred Securities. If the Preferred Securities shall
cease to be 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 the February 1, May 1, August 1 or
November 1, as the case may be, 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


<Page>

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 dissolution, winding-up or termination of the Trust,
the Holders of the Securities on the date of such dissolution, winding-up or
termination, as the case may be, 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 of the Trust an amount equal to the
aggregate of the stated liquidation amount of $25 per Security plus accrued and
unpaid Distributions thereon to the date of payment (such amount being the
"Liquidation Distribution"), unless, in connection with such dissolution,
winding-up or termination, 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 dissolution, 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) The Securities are subject to
redemption in accordance herewith at any time after August 22, 2006 and, in
certain circumstances, following the occurrence of a Special Event (as defined
below).

                  (b) Upon the repayment of the Debentures in whole or in part,
whether at maturity or upon redemption (either at the option of the Debenture
Issuer or pursuant to a Special Event in each case as described below), the
proceeds from such repayment or payment shall be simultaneously applied to
redeem Securities having an aggregate liquidation amount equal to the aggregate
principal amount of the Debentures so repaid or redeemed 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").
Holders will be given not less than 30 nor more than 60 days' notice of any such
redemption.


<Page>

                  (c) 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 redeemed as
described in Section 4(h)(ii) below.

                  (d) The Sponsor shall have the right at any time, upon notice
to the Regular Trustees, to elect to terminate the Trust, and upon receipt of
such notice, the Regular Trustees shall dissolve the Trust and, after
satisfaction of creditors of the Trust, 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 of, and accrued and unpaid interest equal to accrued and unpaid
Distributions on, and having the same record date for payment as, the
Securities, to be distributed to the Holders of the Securities in liquidation of
such Holders' interests in the Securities within 90 days following receipt of
the Sponsor's notice of election.

                  (e) If, at any time, a Tax Event or an Investment Company
Event (each as defined below, and each a "Special Event") has occurred and is
continuing, the Company shall have the right, upon not less than 30 nor more
than 60 days notice, to redeem the Securities in whole but not in part, for cash
in the amount of the Redemption Price, within 90 days following the occurrence
of such Special Event, and, following such redemption, Trust Securities with an
aggregate liquidation amount equal to the aggregate principal amount of the
Securities so redeemed shall be redeemed by PLC Capital at the Redemption Price;
PROVIDED, HOWEVER, that if at the time there is available to the Company or the
Trust the opportunity to eliminate, within such 90 day period, the Tax Event by
taking some Ministerial Action, such as filing a form or making an election or
pursuing some other similar reasonable measure that has no adverse effect on PLC
Capital, the Company or the holders of the Trust Securities, the Company or PLC
Capital will pursue such measure in lieu of a redemption. If the Company does
not elect either to distribute the Securities to the holders of the Preferred
Securities in liquidation of PLC Capital or to redeem the Securities, the Trust
Securities shall remain outstanding and, in the event a Special Event is
continuing, Additional Interest (as defined in Section 2.18 of Supplemental
Indenture No. 5, dated as of August 22, 2001, to the Indenture) will be payable
on the Securities.

         "Tax Event" means the receipt by the Company of 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, on or after the day before the date of
issuance of the Preferred Securities under the Declaration of Trust, 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, which
amendment or change is effective or which interpretation, application or
pronouncement is announced on or after the day before the date of issuance of
the Preferred Securities under the Declaration of Trust, there is more than an
insubstantial increase in the risk that (x) PLC Capital is, or will be within 90
days of the date thereof, subject to U.S. federal income tax with respect to
income received or accrued on the Securities, (y) interest payable by the
Company on the Securities is not, or within 90 days of the date thereof, will
not be,


<Page>

deductible, in whole or in part, for U.S. federal income tax purposes, or (z)
PLC Capital is, or will be within 90 days of the date thereof, subject to
more than a de minimis amount of other taxes, duties or other governmental
charges.

<Page>



         "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 (an "Investment Company Event
Opinion") 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 a 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 dated August 17, 2001 relating
to the offer and sale of the Preferred Securities.

         "Ministerial Action" means the filing of a form, making an election, or
pursuing some other similar reasonable measure that has no adverse effect on the
Trust, the Debenture Issuer, the Sponsor or the Holders.

         After the date for any distribution of Debentures upon dissolution of
the Trust: (I) the Securities will no longer be deemed to be outstanding, (II)
The Depository Trust Company (the "Depository") 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 (III) any
certificates representing Securities, except for certificates representing
Preferred Securities held by the Depository or its nominee (or any 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
distribution 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.

                  (f) 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.

                  (g) 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.

                  (h)  "Redemption or Distribution Procedures."



<Page>


                           (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 Securities, it being understood
         that, in respect of Preferred Securities registered in the name of and
         held of record by the Depository or its nominee (or any successor
         Clearing Agency or its 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 Depository 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 Depository 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 and all rights
         of Holders of such Securities so called for redemption will cease,
         except the right of the


<Page>

         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 (without any interest or other payment in respect of any such
         delay) except that, if such Business Day falls in the next calendar
         year, such payment will be made on the immediately preceding
         Business Day, in each case with the same force and effect as if made
         on such date fixed for redemption. If payment of the Redemption
         Price in respect of any 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 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 of this Annex I and as otherwise required by law and the
Declaration, the Holders of the Preferred Securities will have no voting rights.

                  (b) Subject to the requirements set forth in this paragraph,
the Holders of a Majority in liquidation amount of the Preferred Securities,
voting separately as a class may direct the time, method, and place of
conducting any proceeding for any remedy available to the 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 5.7 of the Indenture, or (III) exercise any right to rescind or
annul a declaration that the principal of all the Debentures shall be due and
payable, provided, however, that, where a consent or action under the Indenture
would require the consent or act of the Holders of greater than a majority of
the Holders in principal amount of


<Page>

Debentures affected thereby (a "Super Majority"), 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 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 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 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.
Notwithstanding any payments made to such Holder by the Debenture Issuer in
connection with such proceeding, the Debenture Issuer shall remain obligated
to pay the principal of or interest on the Debentures held by the Trust or
the Institutional Trustee, and the Debenture Issuer shall be subrogated to
the rights of the Holders of Preferred Securities with respect to payments on
the Preferred Securities to the extent of any payments made by the Debenture
Issuer to such Holder in any such proceeding. Except as provided in the
second 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


<Page>

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) and (c) of this Annex I 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 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 5.7 of the Indenture, or (III)
exercise any right to rescind or annul a declaration that the principal of all
the Debentures shall be due and payable, 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 affected thereby (a
"Super Majority"), 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.

         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 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.


<Page>

         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 as a class, will be entitled to vote on such amendment or
proposal (but not on any other amendment or proposal) and such amendment or
proposal shall not be effective except with the approval of the Holders of at
least a Majority in liquidation amount of the Securities, voting together as a
single class; provided, however, if any amendment or proposal referred to in
clause (i) above would adversely affect only the Preferred Securities or only
the Common Securities, then only the affected class will be entitled to vote on
such amendment or proposal and such amendment or proposal shall not be effective
except with the approval of a Majority in liquidation amount of such class of
Securities.

                  (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 or the Debentures, 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 a consent under the Indenture would require
the consent of the holders of greater than a majority in 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 this Annex I 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


<Page>

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 with, 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. 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.

         12. NO PREEMPTIVE RIGHTS. The Holders of the Securities shall have no
preemptive rights to subscribe for any additional securities.

         13. MISCELLANEOUS. The foregoing terms set forth in this Annex I
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),
and the Indenture to any Holder without charge on written request to the Sponsor
at its principal place of business.

Security (other than a transfer of this Preferred Security as a whole by the

limited circumstances.

         Unless this Preferred Security is presented by an authorized

          7-1/2% Trust Originated Preferred Securities(SM) ("TOPrS"(SM))
                 (liquidation amount $25 per Preferred Security)

         PLC CAPITAL TRUST III, a statutory business trust formed under the laws
of the State of Delaware (the "Trust"), hereby certifies that ____________ (the
"Holder") is the registered owner of preferred securities of the Trust
representing undivided beneficial interests in the assets of the Trust
designated the 7-1/2% Trust Originated Preferred Securities(SM) (liquidation
amount $25 per Preferred Security) (the "Preferred Securities"). The Preferred
Securities are transferable on the books and records of the Trust, in person or
by a duly authorized attorney, upon surrender of this certificate duly endorsed
and in proper form for transfer. The designation, rights, privileges,
restrictions, preferences and other terms and provisions of


<Page>

the Preferred Securities represented hereby are issued and shall in all
respects be subject to the provisions of the Amended and Restated Declaration
of Trust of the Trust dated as of August 22, 2001, as the same may be amended
from time to time (the "Declaration"), including the designation of the terms
of the Preferred Securities as set forth in Annex I to the Declaration.
Capitalized terms used herein but not defined shall have the meaning given
them in the Declaration. The Holder is entitled to the benefits of the
Preferred Securities Guarantee to the extent provided therein. The Sponsor
will provide a copy of the Declaration, the Preferred Securities Guarantee
and the Indenture to the Holder without charge upon written request to the
Trust at its principal place of business.

         Upon receipt of this certificate, the Holder is bound by the
Declaration and is entitled to the benefits thereunder.

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

         Distributions payable on each Preferred Security will be fixed at a
rate per annum of 7-1/2% (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
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 90-day quarter.

         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 November 15, 2001, to Holders of record
one (1) Business Day prior to such payment dates, which payment dates shall
correspond to the interest payment dates on the Debentures; provided however,
that if the Preferred Securities are not then in book-entry only form, such
Distributions shall be paid to the Holders of record on the February 1, May 1,
August 1 or November 1, as the case may be, prior to such payment dates. 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


<Page>


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 record
date immediately preceding 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.

         IN WITNESS WHEREOF, the Trust has executed this certificate this _____

Debenture Issuer; 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

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

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
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 90-day quarter.

         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 November 15, 2001, to Holders of record
one (1) Business Day prior to such payment dates, which payment dates shall
correspond to the interest payment dates on the Debentures; provided, however,
that if the Preferred Securities are not then in book-entry only form, such
Distributions shall be paid to the Holders of record on the February 1, May 1,
August 1 or November 1, as the case may be, prior to such payment dates. 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 record date immediately preceding 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.
