                      (a)    This Trust Agreement is subject to the provisions

Trust Agreement conflicts with the duties imposed by Sections 310 to 317,
inclusive, of the Trust Indenture Act, such imposed duties shall control.

                      (d)    The application of the Trust Indenture Act to
this Trust Agreement shall not affect the Trust's classification as a grantor
trust for United States federal income tax purposes.

                      (a)    Each of the Sponsor and the Administrative
Trustees on behalf of the Trust shall provide the Property Trustee (i), except
while the Capital Securities are represented by one or more Global Securities,

other time, within 30 days of receipt by the Trust of a written request from
the Property Trustee for a List of Holders, as of a date no more than 15 days

neither the Sponsor nor the Administrative Trustees on behalf of the Trust
shall be obligated to provide such List of Holders at any time the List of
Holders does not differ from the most recent List of Holders given to the
Property Trustee by the Sponsor and the Administrative Trustees on behalf of
the Trust. The Property Trustee shall preserve, in as current a form as is
reasonably practicable, all information contained in Lists of Holders given to
it or which it receives in the capacity as Paying Agent (if acting in such

               SECTION 2.6.   Trust Enforcement Events; Waiver.

                      (a)    The Holders of a Majority in Liquidation Amount
of the Capital Securities may, by vote or written consent, on behalf of the
Holders of all of the Capital Securities, waive any past Trust Enforcement
Event in respect of the Capital Securities and its consequences, provided
that, if the underlying Indenture Event of Default:

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

                             (ii)    requires the consent or vote of the
                      Holders of greater than a majority in principal amount
                      of the Debentures (a "Super Majority") to be waived
                      under the Indenture, the related Trust Enforcement Event
                      under the Trust Agreement may only be waived by the vote
                      or written consent of the Holders of at least the
                      proportion in liquidation amount of the Capital
                      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
Trust Agreement and the Securities, as permitted by the Trust Indenture Act.
Upon such waiver, any such default shall cease to exist, and any Trust
Enforcement Event with respect to the Capital Securities arising therefrom
shall be deemed to have been cured, for every purpose of this Trust Agreement
and the Capital Securities, but no such waiver shall extend to any subsequent
or other Trust Enforcement Event with respect to the Capital Securities or
impair any right consequent thereon. Any waiver by the Holders of the Capital
Securities of a Trust Enforcement Event with respect to the Capital Securities
shall also be deemed to constitute a waiver by the Holders of the Common
Securities of any such Trust Enforcement Event with respect to the Common
Securities for all purposes of this Trust Agreement without any further act,
vote, or consent of the Holders of the Common Securities.

                      (b)    The Holders of a Majority in Liquidation Amount
of the Common Securities may, by vote or written consent, on behalf of the
Holders of all of the Common Securities, waive any past Trust Enforcement
Event in respect of the Common Securities and its consequences, provided that,
if the underlying Indenture Event of Default:

                                      9
<PAGE>

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

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

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

                      (c)    A waiver of an Indenture Event of Default by the
Property Trustee at the direction of the Holders of the Capital Securities
constitutes a waiver of the corresponding Trust Enforcement Event with respect
to the Capital Securities under this Trust Agreement. 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 Trust Agreement and the Securities, as
permitted by the Trust Indenture Act.

               SECTION 2.7.   Trust Enforcement Event; Notice.

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

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

                             (i)     a default under Sections 5.1(1) and
                      5.1(2) of the Indenture; or

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

                                 ORGANIZATION

               SECTION 3.1.   Name and Organization.

               The Trust hereby continued is named "Banknorth Capital Trust

Holders of the Capital Securities and Common Securities and the Capital

which is contrary to such classification.

               Subject to the limitations provided in this Trust Agreement and
to the specific duties of the Property Trustee, the Administrative Trustees
shall have exclusive authority to carry out the purposes of the Trust. An
action taken by the Administrative Trustees in accordance with their powers
shall constitute the act of and serve to bind the Trust and an action taken by
the Property Trustee on behalf of the Trust in accordance with its powers
shall constitute the act of and serve to bind the Trust. In dealing with the
Trustees acting on behalf of the Trust, no Person shall be required to inquire
into the authority of

                                      11
<PAGE>

the Trustees to bind the Trust. Persons dealing with the Trust are entitled to
rely conclusively on the power and authority of the Trustees as set forth in
this Trust Agreement.

                      (a)    Except as expressly set forth in this Trust
Agreement and except if a meeting of the Administrative Trustees is called

to act, any power of the Administrative Trustees may be exercised by, or with
the consent of, any one such Administrative Trustee.

                      (b)    Except as otherwise required by the Business
Trust Act or applicable law, any Administrative Trustee is authorized to
execute on behalf of the Trust any documents which the Administrative Trustees
have the power and authority to cause the Trust to execute pursuant to Section
3.6(b).

                      (c)    An Administrative Trustee may, by power of
attorney consistent with applicable law, delegate to any other natural person
over the age of 21 his or her power for the purposes of signing any documents

               Except as provided in Section 3.8 with respect to the
Debentures and the Property Account or as otherwise provided in this Trust
Agreement, legal title to all assets of the Trust shall be vested in the

Trust, but shall have an undivided beneficial ownership interest in the assets
of the Trust.

                              Trustees.

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

                      (and, for purposes specified in (i) through (iii) above,

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

                      such a way as to vary the Trust assets;

                             (vi)    possess any power or otherwise act in
                      such a way as to vary the terms of the Securities in any
                      way whatsoever (except to the extent expressly
                      authorized in this Trust Agreement or by the terms of
                      the Securities);

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

                             (viii)  other than as provided in this Trust
                      Agreement or by the terms of the Securities, (A) direct
                      the time, method and place of exercising any trust or
                      power conferred upon the Debenture Trustee with respect
                      to the Debentures, (B) waive any past default that is
                      waivable 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 counsel to the effect that such modification
                      will not cause more than an insubstantial risk that the
                      Trust will be deemed an investment company required to
                      be registered under the Investment Company Act, or that
                      the Trust will be classified as other than a grantor
                      trust for United States federal income tax purposes;

                             (ix)    take any action inconsistent with the
                      status of the Trust as a grantor trust for United States
                      federal income tax purposes; or

                             (x)     revoke any action previously authorized
                      or approved by vote of the Holders of the Capital
                      Securities.

               SECTION 3.8.   Powers and Duties of the Property Trustee.

                      (a)    The legal title to the Debentures shall be owned
by and held of record in the name of the Property Trustee for the benefit of
the Trust and the Holders of the Securities. The right, title and interest of
the Property Trustee to the Debentures shall vest automatically in each Person
who may hereafter be appointed as Property Trustee in accordance with Section
6.6. 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 Property Trustee shall not transfer its
right, title and interest in the Debentures to the Administrative Trustees or
to the Delaware Trustee (if the Property Trustee does not also act as Delaware
Trustee).

                      (c)    The Property Trustee shall:

                             (i)     establish and maintain a segregated
                      non-interest bearing trust account (the "Property
                      Account") in the name of and under the exclusive control
                      of the Property 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 Property
                      Trustee, deposit such funds into the Property Account
                      and make payments to the Holders of the Capital
                      Securities and Holders of the Common Securities from the
                      Property Account in accordance with Section 7.2. Funds
                      in

                                      15
<PAGE>

                      the Property Account shall be held uninvested until
                      disbursed in accordance with this Trust Agreement. The
                      Property 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 Capital Securities by a "nationally
                      recognized statistical rating organization", within the
                      meaning of Rule 436(g)(2) under the Securities Act;

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

                             (iii)   upon written notice of distribution
                      issued by the Administrative Trustees in accordance with
                      the terms of the Securities, engage in such ministerial
                      activities as so directed and as shall be necessary or
                      appropriate to effect the distribution of the Debentures
                      to Holders of Securities upon the occurrence of a
                      Special Event.

                      (d)    The Property Trustee shall take all actions and
perform such duties as may be specifically required of the Property Trustee
pursuant to the terms of this Trust Agreement and the Securities.

                      (e)    The Property Trustee shall take any Legal Action
which arises out of or in connection with a Trust Enforcement Event of which a
Responsible Officer of the Property Trustee has actual knowledge or the
Property Trustee's duties and obligations under this Trust Agreement or the
Trust Indenture Act; provided, however, that if a Trust Enforcement Event has
occurred and is continuing and such event is attributable to the failure of
the Debenture Issuer to pay interest, principal or other required payments on
the Debentures on the date such interest, principal or other required payments
are otherwise payable (or in the case of redemption, on the redemption date),
then a Holder of Capital Securities may directly institute a proceeding
against the Debenture Issuer for enforcement of payment to such Holder of the
principal of or interest on Debentures having a principal amount equal to the
aggregate liquidation amount of the Capital Securities of such Holder (a
"Direct Action") on or after the respective due date specified in the
Debentures. Notwithstanding anything to the contrary in this Trust Agreement
or the Indenture, the Debenture Issuer shall have the right to set-off any
payment it is otherwise required to make under the Indenture in respect of any
Capital Security to the extent the Debenture Issuer has heretofore made, or is
currently on the date of such payment making, a payment under the Guarantee
relating to such Capital Security or under Section 5.8 of the Indenture.

                      (f)    The Property Trustee shall continue to serve as
a Trustee until 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 Property Trustee has been
                      appointed and has accepted that appointment in
                      accordance with Section 6.6.

                      (g)    The Property 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 a Trust Enforcement Event actually known to a
Responsible Officer of the Property Trustee occurs and is continuing, the
Property 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)    The Property Trustee may authorize one or more
Persons (each, a "Paying Agent") to pay Distributions, redemption payments or
liquidation payments on behalf of the Trust with respect to all Securities and
any such Paying Agent shall comply with Section 317 (b) of the Trust Indenture
Act. Any Paying Agent may be removed by the Property Trustee at any time and a
successor Paying Agent or additional Paying Agents may be appointed at any
time by the Property Trustee.

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

               The Property Trustee shall 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 Property Trustee shall
have no power to, and 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
                              Property Trustee.

                      (a)    The Property Trustee, before the occurrence of
any Trust Enforcement Event and after the curing of all Trust Enforcement
Events that may have occurred, shall undertake to perform only such duties as
are specifically set forth in this Trust Agreement and no implied covenants
shall be read into this Trust Agreement against the Property Trustee. In case
a Trust Enforcement Event has occurred (that has not been cured or waived
pursuant to Section 2.6) of which a Responsible Officer of the Property
Trustee has actual knowledge, the Property Trustee shall exercise such of the
rights and powers vested in it by this Trust Agreement, 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 Trust Agreement shall be
construed to relieve the Property 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 a Trust
                      Enforcement Event and after the curing or waiving of all
                      such Trust Enforcement Events that may have occurred:

                                     a.     the duties and obligations of the
                                            Property Trustee shall be
                                            determined solely by the express
                                            provisions of this Trust Agreement
                                            and the Property Trustee shall not
                                            be liable except for the
                                            performance of such duties and
                                            obligations as are specifically
                                            set forth in this Trust Agreement,
                                            and no implied covenants or
                                            obligations shall be read into
                                            this Trust Agreement against the
                                            Property Trustee; and

                                     b.     in the absence of bad faith on the
                                            part of the Property Trustee, the
                                            Property Trustee may conclusively
                                            rely, as to the truth of the
                                            statements and the correctness of
                                            the opinions expressed therein,
                                            upon any certificates or opinions
                                            furnished to the Property Trustee
                                            and conforming to the requirements
                                            of this Trust Agreement; but in
                                            the case of any such certificates
                                            or opinions that by any provision
                                            hereof are specifically required
                                            to be

                                            furnished to the Property Trustee,
                                            the Property Trustee shall be
                                            under a duty to examine the same
                                            to determine whether or not they
                                            substantially conform to the
                                            requirements of this Trust
                                            Agreement but need not confirm or
                                            investigate the accuracy of any
                                            mathematical calculations or other
                                            facts stated therein;

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

                             (iii)   the Property Trustee shall not be liable
                      with respect to any action taken or omitted to be taken
                      by it without negligence, in good faith in accordance
                      with the direction of 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 Property
                      Trustee, or exercising any trust or power conferred upon
                      the Property Trustee under this Trust Agreement;

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

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

                             (vi)    the Property 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 Property 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 Property Trustee need not be
                      segregated from other funds held by it except in
                      relation to the Property Account maintained by the
                      Property Trustee pursuant to Section 3.8(c)(i) and
                      except to the extent otherwise required by law; and

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

               SECTION 3.10.  Certain Rights of Property Trustee.

                      (a)    Subject to the provisions of Section 3.9:

                             (i)     the Property Trustee may conclusively
                      rely and shall be fully protected in acting or
                      refraining from acting upon any resolution, certificate,
                      statement, instrument, opinion, report, notice, request,
                      direction, consent, order, bond, debenture, note, other
                      evidence of indebtedness or other paper or document
                      (whether in its original or facsimile form) believed by
                      it to be genuine and to have been signed, sent or
                      presented by the proper party or parties;

                             (ii)    any direction or act of the Sponsor or
                      the Administrative Trustees contemplated by this Trust
                      Agreement shall be sufficiently evidenced by an
                      Officer's Certificate;

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

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

                             (v)     the Property Trustee may consult with
                      counsel of its choice 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, such
                      counsel may be counsel to the Sponsor or any of its
                      Affiliates, and may include any of its employees. The
                      Property Trustee shall have the right at any time to
                      seek instructions concerning the administration of this
                      Trust Agreement from any court of competent
                      jurisdiction;

                             (vi)    the Property Trustee shall be under no
                      obligation to exercise any of the rights or powers
                      vested in it by this Trust Agreement at the request or
                      direction of any Holder, unless such Holder shall have
                      provided to the Property Trustee security and indemnity,
                      reasonably satisfactory to the Property Trustee, against
                      the costs, expenses (including reasonable attorneys'
                      fees and expenses and the expenses of the Property
                      Trustee's agents, nominees or custodians) and
                      liabilities that might be incurred by it in complying
                      with such request or direction, including such
                      reasonable advances as may be requested by the Property
                      Trustee; provided that, nothing contained in this
                      Section 3.10(a) shall be taken to relieve the Property
                      Trustee, upon the occurrence of a Trust Enforcement
                      Event, of its obligation to exercise the rights and
                      powers vested in it by this Trust Agreement;

                             (vii)   the Property Trustee shall not be bound
                      to make any investigation into the facts or matters
                      stated in any resolution, certificate, statement,
                      instrument, opinion, report, notice, request, direction,
                      consent, order, bond, debenture, note, other evidence of
                      indebtedness or other paper or document, but the
                      Property Trustee, in its discretion, may make such
                      further inquiry or investigation into such facts or
                      matters as it may see fit at the expense of the Sponsor
                      and shall incur no liability of any kind by reason of
                      such inquiry or investigation;

                             (viii)  the Property 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 Property
                      Trustee shall not be responsible for any misconduct or
                      negligence on the part of any agent or attorney
                      appointed with due care by it hereunder, provided that
                      such agent, custodian, nominee or attorney is a United
                      States Person as defined in Section 7701(a)(30) of the
                      Code;

                             (ix)    any authorized or required action taken
                      by the Property Trustee or its agents hereunder shall
                      bind the Trust and the Holders of the Securities, and
                      the signature of the Property 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 Property Trustee to
                      so act or as to its compliance with any of the terms and
                      provisions of this Trust Agreement, both of which shall
                      be conclusively evidenced by the Property Trustee's or
                      its agent's taking such action;

                             (x)     whenever in the administration of this
                      Trust Agreement the Property Trustee shall deem it
                      desirable to receive instructions with respect to
                      enforcing any remedy or right or taking any other action
                      hereunder, the Property Trustee (i) may request
                      instructions from the Holders of the 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 Property 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
                      protected in conclusively relying on or acting in or
                      accordance with such instructions;

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

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

                             (xiii)  without prejudice to any other rights
                      available to the Property Trustee under applicable law,
                      when the Property Trustee incurs expenses or renders
                      services in connection with a bankruptcy, 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; and

                             (xiv)   the Property Trustee shall not be charged
                      with knowledge of a Trust Enforcement Event unless a
                      Responsible Officer of the Property Trustee obtains
                      actual knowledge of such event or the Property Trustee
                      receives written notice of such event from Holders
                      holding more than a Majority in Liquidation Amount of
                      the Capital Securities;

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

               SECTION 3.13.  Not Responsible for Recitals or Issuance of
                              Securities.

               The recitals contained in this Trust Agreement and the
Securities shall be taken as the statements of the Sponsor, and the Trustees
do not assume any responsibility for their correctness. The Trustees make no
representations as to the value or condition of the property of the Trust or
any part thereof. The Trustees make no representations as to the validity or
sufficiency of this Trust Agreement, the Securities, the Debentures or the
Indenture.

               SECTION 3.14.  Duration of Trust.

                      (b)    The Trust may, at the request of the Sponsor and
with the consent of the Administrative Trustees or, if there are more than

Holders of the Securities, the Delaware Trustee or the Property Trustee,
consolidate, amalgamate, merge with or into, or be replaced by or convey,
transfer or lease its properties substantially as an entirety to a trust
organized as such under the laws of any State; provided, that:

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

                                     a.     expressly assumes all of the
                                            obligations of the Trust with
                                            respect to the Securities; or

                                     b.     substitutes for the Capital
                                            Securities other securities having
                                            substantially the same terms as
                                            the Capital Securities (the
                                            "Successor Securities") so long as
                                            the Successor Securities rank the
                                            same as the Capital Securities
                                            rank in priority with respect to
                                            Distributions and payments upon
                                            liquidation, redemption and
                                            otherwise;

                             (ii)    the Debenture Issuer expressly appoints a
                      trustee of such Successor Entity that possesses the same
                      powers and duties as the Property Trustee as the holder
                      of the Debentures;

                             (iii)   the Capital 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 any other or organization on
                      which the Capital Securities are then listed or quoted;

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

                             (v)     such merger, consolidation, amalgamation,
                      replacement, conveyance, transfer or lease does not
                      adversely affect the rights, preferences and privileges
                      of the Holders of the Capital Securities (including any
                      Successor Securities) in any material respect;

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

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

                                     a.     such merger, consolidation,
                                            amalgamation, replacement,
                                            conveyance, transfer or lease does
                                            not adversely affect the rights,
                                            preferences and privileges of the
                                            Holders of the Capital Securities
                                            (including any Successor
                                            Securities) in any material
                                            respect;

                                     b.     following such merger,

                                            or lease neither the Trust nor the
                                            Successor Entity will be required
                                            to register as an Investment
                                            Company; and

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

                             (viii)  the Sponsor or any permitted successor or
                      assignee owns all of the common securities and
                      guarantees the obligations of such Successor Entity
                      under the Successor Securities at least to the extent
                      provided by the Securities Guarantee and such Successor
                      Entity expressly assumes all of the obligations of the
                      Trust with respect to the Trustees.

                      (c)    Notwithstanding Section 3.15(b), the Trust shall
not, except with the consent of Holders of 100% in aggregate liquidation
amount of the Securities, 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 other entity or permit any other entity
to consolidate, amalgamate, merge with or into, or replace it, if such
consolidation, amalgamation, merger, replacement, conveyance, transfer or
lease would cause the Trust or Successor Entity to be classified as other than
a grantor trust for United States federal income tax purposes and each Holder
of the Securities not to be treated as owning an undivided interest in the
Debentures.

               SECTION 3.16.  Property Trustee May File Proofs of Claim.

               In case of the pendency of any receivership, insolvency,
liquidation, bankruptcy, reorganization, arrangement, adjustment, composition
or other similar judicial proceeding relative to the Trust or any other
obligor upon the Securities or the property of the Trust or of such other
obligor or their creditors, the Property Trustee (irrespective of whether any
Distributions on the Securities shall then be due and payable as therein
expressed or by declaration or otherwise and irrespective of whether the
Property Trustee shall have made any demand on the Trust for the payment of
any past due Distributions) shall be entitled and empowered, to the fullest
extent permitted by law, by intervention in such proceeding or otherwise:

                      (a)    to file and prove a claim for the whole amount of
any Distributions owing and unpaid in respect of the Securities (or, if the
Securities are original issue discount Securities, such portion of the
liquidation amount as may be specified in the terms of such Securities) and to
file such other papers or documents as may be necessary or advisable in order
to have the claims of the Property Trustee (including any claim for the
reasonable compensation, expenses, disbursements and advances of the Property
Trustee, its and counsel) and of the Holders allowed in such judicial
proceeding, and

                      (b)    to collect and receive any moneys or other
property payable or deliverable on any such claims and to distribute the same;

and any custodian, receiver, assignee, trustee, liquidator, sequestrator or
other similar official in any such judicial proceeding is hereby authorized by
each Holder to make such payments to the Property Trustee and, in the event
the Property Trustee shall consent to the making of such payments directly to
the Holders, to pay to the Property Trustee any amount due it for the
reasonable compensation, expenses,

                                      23
<PAGE>

disbursements and advances of the Property Trustee, its agents and counsel,
and any other amounts due the Property Trustee.

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

connection with the acceptance or administration of the trust or trusts
hereunder, including the costs and expenses of defending either of them

               The Sponsor agrees to pay the Property Trustee and the Delaware
Trustee from time to time such compensation for all services rendered by the

upon in writing by the Sponsor and the Property Trustee or the Delaware

business trust and not to voluntarily dissolve, wind up, liquidate or be
terminated, except as permitted by this Trust Agreement, (iii) to use its
commercially reasonable efforts to ensure that the Trust will not be an
investment company for purposes of the Investment Company Act, and (iv) to
take no action which would be reasonably likely to cause the Trust to be
classified as other than a grantor trust for United States federal income tax
purposes.

                      (a)    There shall at all times be one Trustee (which

                      the Commission to act as an institutional trustee under
                      the Trust Indenture Act, authorized under such laws to

                      by federal, State, Territorial or District of Columbia
                      authority. If such corporation publishes reports of
                      condition at least annually, pursuant to law or to the
                      requirements of the supervising or examining authority
                      referred to above, then for the purposes of this Section
                      6.3(a)(ii), the combined capital and surplus of such
                      corporation shall be deemed to be its combined capital

"conflicting interest" within the meaning of Section 310(b) of the Trust
Indenture Act, the Property Trustee and the Holder of the Common Securities
(as if it were the obligor referred to in Section 310(b) of the Trust
Indenture Act) shall in all respects comply with the provisions of Section
310(b) of the Trust Indenture Act.

                      (d)    The Guarantee shall be deemed to be specifically
described in this Trust Agreement for purposes of clause (i) of the first
proviso contained in Section 310(b) of the Trust Indenture Act.

               SECTION 6.4.   Qualifications of Administrative Trustees and

                             (i)     until the issuance of any Securities, by

                                            has been appointed and has
                                            accepted such appointment by

                                            Successor Property Trustee and

                                            Sponsor and the resigning Property
                                            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 Trustee and delivered to the Trust,
                      the Sponsor and the resigning Delaware Trustee.

                      (d)    The Holders of the Common Securities shall use

                      (e)    If no Successor Property Trustee or Successor
Delaware Trustee, as the case may be, shall have been appointed and accepted
appointment as provided in this Section 6.6 within 60 days after delivery to
the Sponsor and the Trust of an instrument of resignation or removal, the
resigning or removed Property Trustee or Delaware Trustee, as applicable, may
petition at the expense of the Sponsor any court of competent jurisdiction in
the U.S. for appointment of a Successor Property Trustee or Successor Delaware
Trustee, as applicable. Such court may thereupon, after prescribing such
notice, if any, as it may deem proper, appoint a Successor Property Trustee or
Successor Delaware Trustee, as the case may be.

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

               SECTION 6.7.   Vacancies among Trustees.

               If a Trustee ceases to hold office for any reason and the
number of Trustees is not reduced pursuant to Section 6.1, or if the number of
Trustees is increased pursuant to Section 6.1, a vacancy shall occur. A
resolution certifying the existence of such vacancy by the Administrative
Trustees or, if there are more than two, a majority of the Administrative
Trustees shall be conclusive evidence of the existence of such vacancy. The
vacancy shall be filled with a Trustee appointed in accordance with Section
6.6.

               SECTION 6.8.   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, dissolve or terminate the Trust.
Whenever a vacancy in the number of Administrative Trustees shall occur, until
such vacancy is filled by the appointment of an Administrative Trustee in
accordance with Section 6.6, the Administrative Trustees in office, regardless
of their number, shall have all the powers granted to the Administrative
Trustees and shall discharge all the duties imposed upon the Administrative
Trustees by this Trust Agreement.

               SECTION 6.9.   Meetings.

<PAGE>

               If there is more than one Administrative Trustee, meetings of
the Administrative Trustees shall be held from time to time upon the call of
any Administrative Trustee. Regular meetings of the Administrative Trustees
may be held at a time and place fixed by resolution of the Administrative
Trustees. Notice of any in-person meetings of the Administrative 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 Administrative
Trustees shall be hand delivered or otherwise delivered in writing (including
by facsimile, with a hard copy by overnight courier) not less than 24 hours
before a 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 an Administrative Trustee at a meeting shall constitute a waiver
of notice of such meeting except where an Administrative 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 Trust Agreement, any action of the
Administrative Trustees may be taken at a meeting by vote of a majority of the
Administrative 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 and without prior written notice by the
unanimous written consent of the Administrative Trustees. In the event there
is only one Administrative Trustee, any and all action of such Administrative
Trustee shall be evidenced by a written consent of such Administrative
Trustee.

               SECTION 6.10.  Delegation of Power.

                      (a)    Any Administrative Trustee may, by power of
attorney consistent with applicable law, delegate to any natural person over
the age of 21 his, her or its power for the purpose of executing any documents
contemplated in Section 3.6 or making any governmental filing; provided that
such person is a United States Person as defined in Section 7701(a)(30) of the
Code.

                      (b)    The Administrative 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 Administrative Trustees or otherwise as
the Administrative Trustees may deem expedient, to the extent such delegation
is not prohibited by applicable law or contrary to the provisions of the
Trust, as set forth herein; provided, that such person is a United States
Person as defined in Section 7701(a)(30) of the Code.

               SECTION 6.11.  Merger, Conversion, Consolidation or Succession

merged or converted or with such Trustee may be consolidated, or any
corporation resulting from any merger, conversion or consolidation to which
such Trustee shall be a party, or any corporation succeeding to all or
substantially all the corporate trust business of such Trustee shall be the
successor of such Trustee hereunder, provided such corporation shall be
otherwise qualified and eligible under this Article, without the execution or
filing of any paper or any further act on the part of any of the parties
hereto.

                             TERMS OF SECURITIES

               SECTION 7.1.   General Provisions Regarding Securities.

                      (a)    The Administrative Trustees shall on behalf of
the Trust issue one class of capital securities representing undivided
beneficial interests in the assets of the Trust and one class of common
securities representing undivided beneficial interests in the assets of the
Trust.

                             (i)     Capital Securities.  The Capital
                      Securities of the Trust have an aggregate liquidation
                      amount with respect to the assets of the Trust of up to
                      Two hundred million dollars ($200,000,000) with respect
                      to the closing of the sale of Capital Securities on one
                      or more occasions. The Capital Securities are hereby
                      designated for identification purposes only as "8% Trust
                      Preferred Securities" (the "Capital Securities"). The
                      Capital Security Certificates evidencing the Capital
                      Securities shall be substantially in the form of Exhibit
                      A to this Trust Agreement, with such changes and
                      additions thereto or deletions therefrom as may be
                      required by ordinary usage, custom or practice or to
                      conform to the rules of any stock exchange on which the
                      Capital Securities are listed or quoted.

                             (ii)    Common Securities.  The Common Securities
                      of the Trust have an aggregate liquidation amount with
                      respect to the assets of the Trust of up to Six million
                      one hundred eighty-five thousand five hundred
                      seventy-five dollars ($6,185,575) with respect to the
                      closing of the sale of Common Securities on one or more
                      occasions. The Common Securities are hereby designated
                      for identification purposes only as "8% Common
                      Securities" (the "Common Securities" and, together with
                      the Capital Securities, the "Securities"). The Common
                      Security Certificates evidencing the Common Securities
                      shall be substantially in the form of Exhibit B to this
                      Trust Agreement, with such changes and additions thereto
                      or deletions therefrom as may be required by ordinary
                      usage, custom or practice.

                      (b)    Payment of Distributions on, and payment of the
Redemption Price upon a redemption of, the Capital Securities and the Common
Securities, as applicable, shall be made Pro Rata based on the liquidation
amount of such Capital Securities and Common Securities; provided, however,
that if on any date on which amounts payable on distribution or redemption, an
Indenture Event of Default shall have occurred and be continuing, no payment
of any Distribution on, or Redemption Price of, any of the Common Securities,
and no other payment on account of the redemption, liquidation or other
acquisition of such Common Securities, shall be made unless payment in full in
cash of all accumulated and unpaid Distributions on all of the outstanding
Capital Securities for all Distribution periods terminating on or prior
thereto, or, in the case of amounts payable on redemption, the full amount of
the Redemption Price for all of the outstanding Capital Securities then called
for redemption, shall have been made or provided for, and all funds available
to the Property Trustee shall first be applied to the payment in full in cash
of all Distributions on, or the Redemption Price of, the Capital Securities
then due and payable. The Trust shall issue no securities or other interests
in the assets of the Trust other than the Capital Securities and the Common
Securities.

                      (c)    The Certificates shall be signed on behalf of the
Trust by an Administrative Trustee. Such signature shall be the manual or
facsimile signature of any present or any future Administrative Trustee. In
case an Administrative Trustee of the Trust who shall have signed any

                                      30
<PAGE>

of the Certificates shall cease to be such Administrative Trustee before the
Certificates so signed shall be delivered by the Trust, such Certificates
nevertheless may be delivered as though the person who signed such
Certificates had not ceased to be such Administrative Trustee; and any
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 Administrative
Trustees of the Trust, although at the date of the execution and delivery of
the Trust Agreement any such person was not such an Administrative Trustee.
Certificates shall be printed, lithographed or engraved or may be produced in
any other manner as is reasonably acceptable to the Administrative Trustees,
as evidenced by their execution thereof, and may have such letters, numbers or
other marks of identification or designation and such legends or endorsements
as the Administrative 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.

               A Certificate representing Capital Securities shall not be
valid until authenticated by the manual signature of an authorized officer of
the Property Trustee. Such signature shall be conclusive evidence that such
Certificate has been authenticated under this Trust Agreement.

               Upon a written order of the Trust signed by one Administrative
Trustee, the Property Trustee shall authenticate the Certificates representing
Capital Securities for original issue. The aggregate amount of Capital
Securities outstanding at any time shall not exceed the liquidation amount set
forth in Section 7.1(a)(i).

               The Property Trustee may appoint an authenticating agent
acceptable to the Trust to authenticate Certificates. An authenticating agent
may authenticate Certificates whenever the Property Trustee may do so. Each
reference in this Trust Agreement to authentication by the Property Trustee
includes authentication by such agent. An authenticating agent has the same
rights as the Property Trustee to deal with the Sponsor or an Affiliate of the
Sponsor.

                      (d)    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.

                      (e)    Upon issuance of the Securities as provided in
this Trust Agreement, the Securities so issued shall be deemed to be validly
issued, fully paid and non-assessable undivided beneficial interests in the
assets of the Trust.

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

                      (g)    The holders of the Securities shall have no
preemptive or similar rights.

               SECTION 7.2.   Distributions.

                      (a)    As owners of undivided beneficial ownership
interests in the Debentures, holders of Securities shall be entitled to
receive cumulative cash Distributions at the rate per annum of 8% of the
stated liquidation amount of $25.00 per Security. Pursuant to the Indenture,
the amount of interest on the Debentures payable for any period shorter than a
full quarterly interest period, and, as a result, Distributions on the
Securities payable for any period shorter than a full quarterly distribution
period shall be computed on the basis of a 30-day month and for periods of
less than a month, the actual number of days elapsed per 30-day month. Subject
to Section 7.1(b), Distributions shall be made on the Capital Securities and
the Common Securities on a Pro Rata basis. Pursuant to the Indenture, interest
on the

                                      31
<PAGE>

Debentures shall, from the date of original issue, accrue and be cumulative,
and, as a result Distributions on the Securities shall, from the date of
original issue, accumulate and be cumulative. Distributions shall be payable
quarterly in arrears on each January 1, April 1, July 1, and October 1 of each
year, commencing April 1, 2002, when, as and if available for payment, by the
Property Trustee, except as otherwise described below. Distributions are
payable only to the extent that payments are made in respect of the Debentures
held by the Property Trustee and to the extent that the Trust has funds
available for the payment of such Distributions in the Property Account.

                      (b)    Pursuant to the Indenture, interest not paid on
the scheduled payment date will accrue and compound quarterly at the rate of
8% per annum, and, as a result, interests on the Debentures not paid on the
scheduled payment date will accrue and compound quarterly at the rate of 8%
per annum (and, as a result) the Distributions on the Securities will
accumulate and compound at the rate of 8% per annum ("Compounded
Distributions"). "Distributions" shall mean ordinary cumulative distributions
together with any Compounded Distributions.

                      (c)    If and to the extent that the Debenture Issuer
makes a payment of interest, premium and/or principal on the Debentures held
by the Property Trustee (the amount of any such payment being a "Payment
Amount"), the Property Trustee shall and is directed, to the extent funds are
available for that purpose, make a Pro Rata distribution of the Payment Amount
to Holders, subject to Section 7.1(b).

                      (d)    Distributions on the Securities shall be payable
to the Holders thereof as they appear on the register of the Trust as of the
close of business on the relevant record dates. While the Capital Securities
are represented by one or more Global Securities, the relevant record dates
shall be the close of business the Business Day preceding such Distribution
payment date; otherwise the relevant record date shall be the fifteenth day
(whether or not a Business Day) preceding such Distribution payment date. At
all times, the Distribution payment dates shall 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, shall
cease to be payable to the Person in whose name such Securities are registered
on the relevant record date, and such defaulted Distribution will instead be
payable to the Person in whose name such Securities are registered on the
special record date or other specified date determined in accordance with this
Trust Agreement. 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), with the
same force and effect as if made on such payment date.

                      (e)    In the event that there is any money or other
property held by or for the Trust that is not accounted for hereunder, such
property shall be distributed Pro Rata among the Holders of the Securities
except as provided in Section 7.1(b).

               SECTION 7.3.   Redemption of Securities.

                      (a)    Upon the repayment or redemption, in whole or in
part, of the Debentures held by the Trust, whether at the stated maturity of
the Debentures or upon earlier redemption as provided in the Indenture, the
proceeds from such repayment or redemption shall be simultaneously applied Pro
Rata (subject to Section 7.1(b)) to redeem Securities having an aggregate
liquidation amount equal to the aggregate principal amount of the Debentures
so repaid or redeemed at the Redemption Price. Holders shall be given not less
than 30 nor more than 60 days notice of such redemption in accordance with
Section 7.4.

                                      32
<PAGE>

                      (b)    On the date fixed for any distribution of
Debentures, upon dissolution of the Trust, (i) the Securities will no longer
be deemed to be outstanding and (ii) certificates representing Securities will
be deemed to represent the Debentures having an aggregate principal amount
equal to the stated liquidation amount of, and bearing accrued and unpaid
interest equal to accumulated and unpaid distributions on, such Securities
until such certificates are presented to the Sponsor or its agent for transfer
or reissuance.

               SECTION 7.4.   Redemption Procedures.

                      (a)    Notice of any redemption of, or notice of
distribution of Debentures in exchange for, the Securities (a
"Redemption/Distribution Notice"), which notice shall be irrevocable, 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 7.4(a), 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 register 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.

                      (b)    If fewer than all the outstanding Securities are
to be so redeemed, the Common Securities and the Capital Securities will be
redeemed Pro Rata (subject to Section 7.1(b)) and the Capital Securities to be
redeemed will be redeemed as described in Section 7.4(c) below. The particular
Capital Securities to be redeemed will be selected on a Pro Rata basis by the
Property Trustee from the outstanding Capital Securities not previously called
for redemption, by such method (including, without limitation, by lot) as the
Property Trustee shall deem fair and appropriate. The Trust may not redeem the
Securities in part unless all accumulated and unpaid Distributions to the date
of redemption have been paid in full on all Securities then outstanding. For
all purposes of this Trust Agreement, unless the context otherwise requires,
all provisions relating to the redemption of Capital Securities shall relate,
in the case of any Capital Security redeemed or to be redeemed only in part,
to the portion of the aggregate liquidation amount of Capital Securities which
has been or is to be redeemed.

                      (c)    Subject to the Trust's fulfillment of the notice
requirements set forth in Section 7.4(a) above, if Securities are to be
redeemed, then (i) with respect to Capital Securities represented by one or
more Global Securities, by 12:00 noon, New York City time, on the redemption
date, provided that the Debenture Issuer has paid the Property Trustee a
sufficient amount of cash in connection with the related redemption or
maturity of the Debentures, the Property Trustee will deposit irrevocably with
the Depositary or its nominee (or successor Clearing Agency or its nominee)
funds sufficient to pay the applicable Redemption Price with respect to the
Capital Securities and will give the Depositary irrevocable instructions and
authority to pay the Redemption Price to the Holders of the Capital Securities
and (ii) with respect to Securities not represented by one or more Global
Securities, provided that the Debenture Issuer has paid the Property Trustee a
sufficient amount of cash in connection with the related redemption or
maturity of the Debentures, the Property Trustee will give the Paying Agent
irrevocable instructions and authority to pay the relevant Redemption Price to
the Holders of such Securities upon surrender of their certificates evidencing
the Capital Securities. Payment of the Redemption Price on the Capital
Securities will be made to the recordholders thereof as they appear on the
register of the Trust on the relevant record date, which shall be one Business
Day prior to the relevant redemption date; provided, however, that with
respect to the Capital Securities not represented by one or more Global
Securities, the relevant record date shall be the date fifteen days prior to
the relevant

                                      33
<PAGE>

redemption date. If any date fixed for redemption of Securities is not a
Business Day, then payment of the Redemption Price payable on such date will
be made on the next succeeding day that is a Business Day (and without any
interest or other payment in respect of any such delay) with the same force
and effect as if made on such date fixed for redemption. If, however, the
Business Day falls in the next calendar year, then payment of the Redemption
Price will be made on the immediately preceding Business Day 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 not paid because the
payment of the Redemption Price on the Debentures is not made, interest will
continue to accrue on the Debentures, and, as a result, Distributions on such
Securities will continue to accumulate at the then applicable rate 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. For these purposes, the
applicable Redemption Price shall not include Distributions which are being
paid to Holders who were Holders on a relevant record date. If a
Redemption/Distribution Notice shall have been given and funds deposited or
paid as required, then immediately prior to the close of business on the date
of such deposit or payment, Distributions will cease to accumulate on the
Securities called for redemption and all rights of Holders of such Securities
so called for redemption will cease, except the right of the Holders to
receive the Redemption Price, but without interest on such Redemption Price,
and from and after the date fixed for redemption, such Securities will cease
to be outstanding.

               Neither the Administrative Trustees nor the Trust shall be
required to register or cause to be registered the transfer of any Securities
that have been called for redemption, except in the case of any Securities
being redeemed in part, any portion thereof not to be redeemed.

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

               SECTION 7.5.   Voting Rights of Capital Securities.

                      (a)    Except as provided under Section 6.6, Section
11.1 and this Article 7 and as otherwise required by the Business Trust Act,
the Trust Indenture Act and other applicable law, the Holders of the Capital
Securities shall have no voting rights.

                      (b)    Subject to the requirement of the Property
Trustee being provided with a tax opinion in certain circumstances set forth
in Section 7.5(d) below, the Holders of a Majority in Liquidation Amount of
the Capital Securities voting separately as a class have the right to direct
the time, method and place of conducting any proceeding for any remedy
available to the Property Trustee, or to direct the exercise of any trust or
power conferred upon the Property Trustee under the Trust Agreement, including
the right to direct the Property Trustee, as Holder of the Debentures, to (i)
exercise the remedies available to it under the Indenture as a Holder of the
Debentures; (ii) consent to any amendment, modification or termination of the
Indenture or the Debentures where such consent shall be required or (iii)
waive any past default and its consequences that is waivable under Section
5.13 of the Indenture; provided, however, that if an Indenture Event of
Default has occurred and is continuing, then the Holders of 25% of the
aggregate liquidation amount of the Capital Securities may direct the Property
Trustee to declare the principal of and interest on the Debentures due and
payable; provided, further, that where a consent or action under the Indenture
would require the consent or act of the Holders of more than a majority of the
aggregate principal amount of Debentures affected thereby, only the Holders of
the percentage of the aggregate stated liquidation amount of the Capital
Securities which is at least equal to the percentage required under the
Indenture may direct the Property Trustee to give such consent to take such
action.

                                      34
<PAGE>

                      (c)    If the Property Trustee fails to enforce its
rights under the Debentures after a Holder of Capital Securities has made a
written request, such Holder of Capital Securities may, to the extent
permitted by applicable law, institute a legal proceeding directly against the
Debenture Issuer to enforce the Property Trustee's rights under the Indenture
without first instituting any legal proceeding against the Property Trustee or
any other Person. In addition, if a Trust Enforcement Event has occurred and
is continuing and such event is attributable to the failure of the Debenture
Issuer to make any interest, principal or other required payments when due
under the Indenture, then a Holder of Capital Securities may directly
institute a Direct Action against the Debenture Issuer on or after the
respective due date specified in the Debentures.

                      (d)    The Property Trustee shall notify all Holders of
the Capital Securities of any notice of any Indenture Event of Default
received from the Debenture Issuer with respect to the Debentures. Such notice
shall state that such Indenture Event of Default also constitutes a Trust
Enforcement Event. Except with respect to directing the time, method, and
place of conducting a proceeding for a remedy, the Property Trustee shall be
under no obligation to take any of the actions described in clause 7.5(b)(i)
and (ii) above unless the Property Trustee has obtained an opinion of
independent tax counsel to the effect that the Trust will not be classified as
an association or publicly traded partnership taxable as a corporation for
United States federal income tax purposes as a result of such action.

                      (e)    In the event the consent of the Property Trustee,
as the Holder of the Debentures, is required under the Indenture with respect
to any amendment or modification of the Indenture, the Property Trustee shall
request the direction of the Holders of the Capital Securities with respect to
such amendment or modification and shall vote with respect to such amendment
or modification as directed by not less than a majority in liquidation amount
of the Capital Securities voting together as a single class; provided,
however, that where a consent under the Indenture would require the consent of
the Holders of more than a majority of the aggregate principal amount of the
Debentures, the Property Trustee may only give such consent at the direction
of the Holders of at least the same proportion in aggregate stated liquidation
amount of the Securities. The Property Trustee shall not take any such action
in accordance with the directions of the Holders of the Securities unless the
Property Trustee has been provided with an opinion of counsel to the effect
that such action will not affect the status of the Trust as a grantor trust
for U.S. federal income tax purposes.

                      (f)    A waiver of an Indenture Event of Default with
respect to the Debentures will constitute a waiver of the corresponding Trust
Enforcement Event.

                      (g)    Any required approval or direction of Holders of
Capital Securities may be given at a separate meeting of Holders of Capital
Securities convened for such purpose, at a meeting of all of the Holders of
Securities or pursuant to written consent. The Administrative Trustees will
cause a notice of any meeting at which Holders of Capital Securities are
entitled to vote to be mailed to each Holder of record of Capital Securities.
Each such notice will include a statement setting forth (i) the date of such
meeting, (ii) a description of any resolution proposed for adoption at such
meeting on which such Holders are entitled to vote and (iii) instructions for
the delivery of proxies.

                      (h)    No vote or consent of the Holders of Capital
Securities shall be required for the Trust to redeem and cancel Capital
Securities or distribute Debentures in accordance with this Trust Agreement
and the terms of the Securities.

                      (i)    Notwithstanding that Holders of Capital
Securities are entitled to vote or consent under any of the circumstances
described above, any of the Securities that are owned at such time by the
Debenture Issuer, any Administrative Trustee or any entity directly or
indirectly controlled by, or

                                      35
<PAGE>

under direct or indirect common control with, the Debenture Issuer or any
Administrative Trustee, shall not be entitled to vote or consent and shall,
for purposes of such vote or consent, be treated as if such Securities were
not outstanding; provided, however, that Persons otherwise eligible to vote to
whom the Debenture Issuer or any of its subsidiaries have pledged Capital
Securities may vote or consent with respect to such pledged Capital Securities
under any of the circumstances described herein.

                      (j)    Subject to Sections 6.6(a) and 7.5(k), Holders of
the Capital Securities shall have no rights to appoint or remove the Trustees,
who may be appointed, removed or replaced solely by the Common Securities
Holder.

                      (k)    If an Indenture Event of Default has occurred and
is continuing, the Property Trustee and the Delaware Trustee may be removed at
such time only by a Majority in Liquidation Amount of the Capital Securities.

                      (l)    The Trustees shall not revoke any action
previously authorized or approved by a vote of the Holders of the Securities,
except by a subsequent vote of the Holders of the Securities.

               SECTION 7.6.   Voting Rights of Common Securities.

                      (a)    Except as provided under Section 6.1(b), this
Section 7.6 or Section 11.1 or as otherwise required by the Business Trust
Act, the Trust Indenture Act or other applicable law or provided by the Trust
Agreement, the Holders of the Common Securities will have no voting rights.

                      (b)    Subject to Sections 6.6(a) and 7.5(k), the
Holders of the Common Securities shall be entitled, in accordance with Article
VI of this Trust Agreement, to vote to appoint, remove or replace any Trustee
or to increase or decrease the number of Trustees.

                      (c)    Subject to Section 2.6 and only after all Trust
Enforcement Events with respect to the Capital Securities have been cured,
waived, or otherwise eliminated and subject to the requirement of the Property
Trustee being provided with a tax opinion in certain circumstances set forth
in this paragraph (c), the Holders of a Majority in Liquidation Amount of the
Common Securities have the right to direct the time, method and place of
conducting any proceeding for any remedy available to the Property Trustee, or
direct the exercise of any trust or power conferred upon the Property Trustee
under this Trust Agreement, including the right to direct the Property
Trustee, as Holder of the Debentures, to (i) exercise the remedies available
to it under the Indenture as a Holder of the Debentures, (ii) consent to any
amendment or modification of the Indenture or the Debentures where such
consent shall be required or (iii) waive any past default and its consequences
that is waivable under Section 5.13 of the Indenture; provided, however, that
where a consent or action under the Indenture would require the consent or act
of the Holders of more than a majority of the aggregate principal amount of
Debentures affected thereby, only the Holders of the percentage of the
aggregate stated liquidation amount of the Common Securities which is at least
equal to the percentage required under the Indenture may direct the Property
Trustee to have such consent or take such action. Except with respect to
directing the time, method, and place of conducting a proceeding for a remedy,
the Property Trustee shall be under no obligation to take any of the actions
described in clause 7.6(c)(i) and (ii) above unless the Property Trustee has
been provided with an opinion of independent tax counsel to the effect that,
as a result of such action, for United States federal income tax purposes the
Trust will not be classified as other than a grantor trust.

                      (d)    If the Property Trustee fails to enforce its
rights under the Debentures after a Holder of Common Securities has made a
written request, such Holder of Common Securities may,

                                      36
<PAGE>

to the extent permitted by applicable law, directly institute a legal
proceeding directly against the Debenture Issuer to enforce the Property
Trustee's rights under the Debentures without first instituting any legal
proceeding against the Property Trustee or any other Person.

                      (e)    A waiver of an Indenture Event of Default with
respect to the Debentures will constitute a waiver of the corresponding Trust
Enforcement Event.

                      (f)    Any required 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 or pursuant to written consent. The Administrative Trustees will
cause a notice of any meeting at which Holders of Common Securities are
entitled to vote 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, (ii) a description of any resolution proposed for adoption at such
meeting on which such Holders are entitled to vote and (iii) instructions for
the delivery of proxies.

                      (g)    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 Debentures in accordance with the Trust Agreement
and the terms of the Securities.

               SECTION 7.7.   Paying Agent.

               In the event that any Capital Securities are not in book-entry
only form, the Trust shall maintain in the Borough of Manhattan, City of New
York, State of New York, an office or agency where the Capital Securities may
be presented for payment ("Paying Agent"). The Trust may appoint the paying
agent and may appoint one or more additional paying agents in such other
locations as it shall determine. The term "Paying Agent" includes any
additional paying agent. The Trust may change any Paying Agent without prior
notice to the Holders. The Trust shall notify the Property Trustee of the name
and address of any Paying Agent not a party to this Trust Agreement. If the
Trust fails to appoint or maintain another entity as Paying Agent, the
Property Trustee shall act as such. The Trust or any of its Affiliates may act
as Paying Agent. The Property Trustee shall initially act as Paying Agent for
the Securities. In the event the Property Trustee shall no longer be the
Paying Agent, the Administrative Trustees shall appoint a successor (which
shall be a bank or trust company acceptable to the Debenture Issuer) to act as
Paying Agent. The Paying Agent shall be permitted to resign as Paying Agent
upon 30 days' written notice to the Property Trustee and the Debenture Issuer.

               SECTION 7.8.   Listing.

               The Sponsor shall use its best efforts to cause the Capital
Securities to be listed on the NYSE.

               SECTION 7.9.   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 Trust
Agreement and in the terms of the Securities. To the fullest extent permitted
by law, any transfer or purported transfer of any Security not made in
accordance with this Trust Agreement shall be null and void.

                      (b)    (i)     Subject to this Article 7, Capital
Securities shall be freely transferable.

<PAGE>

                             (ii)    The Holder of the Common Securities may
                      not transfer the Common Securities except (A) in
                      compliance with a consolidation, merger, sale,
                      conveyance or lease of the Sponsor in compliance with
                      Article VIII of the Indenture or (B) to the Sponsor or
                      an Affiliate thereof in compliance with applicable law,
                      including the Securities Act and applicable state
                      securities and blue sky laws. To the fullest extent
                      permitted by law, any attempted transfer of the Common
                      Securities other than as set forth in the immediately
                      preceding sentence shall be null and void.

                      (c)    The Trust shall cause to be kept at the Corporate
Trust Office of the Property Trustee a register (the register maintained in
such office being herein sometimes referred to as the "Security Register") in
which, subject to such reasonable regulations as it may prescribe, the Trust
shall provide for the registration of Capital Securities and of transfers of
Capital Securities. The Property Trustee is hereby appointed "Security
Registrar" for the purpose of registering Capital Securities and transfers of
Capital Securities as herein provided.

                      (d)    Upon surrender for registration of transfer of
any Security at an office or agency of the Trust designated for such purpose,
the Trust shall execute, and the Property Trustee shall authenticate and
deliver, in the name of the designated transferee or transferees, one or more
new Securities of any authorized denominations and of a like aggregate
principal amount.

                      (e)    At the option of the Holder, Securities may be
exchanged for other Securities of any authorized denominations and of a like
aggregate principal amount, upon surrender of the Securities to be exchanged
at such office or agency. Whenever any Securities are so surrendered for
exchange, the Trust shall execute, and in the case of Capital Securities the
Property Trustee shall authenticate and deliver, the Securities which the
Holder making the exchange is entitled to receive.

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

                      (g)    No service charge shall be made for any
registration of transfer or exchange of Securities, but the Trust may require
payment of a sum sufficient to cover any tax or other governmental charge that
may be imposed in connection with any registration of transfer or exchange of
Securities.

                      (h)    If the Securities are to be redeemed in part, the
Trust shall not be required (A) to issue, register the transfer of or exchange
any Securities during a period beginning at the opening of business 15 days
before the day of the mailing of a notice of redemption of any such Securities
selected for redemption under Section 7.4 and ending at the close of business
on the day of such mailing, or (B) to register the transfer or exchange of any
Security so selected for redemption in whole or in part, except the unredeemed
portion of any Security being redeemed in part.

               SECTION 7.10.  Mutilated, Destroyed, Lost or Stolen
Certificates.

If:

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

                                      38
<PAGE>

                      (b)    there shall be delivered to the Administrative
Trustees such security or indemnity as may be required by them to keep each of
the Trustees, the Sponsor and the Trust harmless,

then, in the absence of notice that such Certificate shall have been acquired
by a bona fide purchaser, any Administrative 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
7.10, the Administrative 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.

               SECTION 7.11.  Deemed Security Holders.

               The Trustees may treat the Person in whose name any Certificate
shall be registered on the register 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 7.12.  Global Securities.

               The Capital Securities may be issued in the form of one or more
Global Securities. If the Capital Securities are to be issued in the form of
one or more Global Securities, then an Administrative Trustee on behalf of the
Trust shall execute and the Property Trustee shall authenticate and deliver
one or more Global Securities that (i) shall represent and shall be
denominated in an amount equal to the aggregate liquidation amount of all of
the Capital Securities to be issued in the form of Global Securities and not
yet cancelled, (ii) shall be registered in the name of the Depositary for such
Global Security or the nominee of such Depositary, and (iii) shall be
delivered by the Property Trustee to such Depositary or pursuant to such
Depositary's instructions. Global Securities shall bear a legend substantially
to the following effect:

               "This Capital Security is a Global Security within the meaning
               of the Trust Agreement hereinafter referred to and is
               registered in the name of The Depository Trust Company, a New
               York corporation (the "Depositary"), or a nominee of the
               Depositary. This Capital Security is exchangeable for Capital
               Securities registered in the name of a person other than the
               Depositary or its nominee only in the limited circumstances
               described in the Trust Agreement and no transfer of this
               Capital Security (other than a transfer of this Capital
               Security as a whole by the Depositary to a nominee of the
               Depositary or by a nominee of the Depositary to the Depositary
               or another nominee of the Depositary) may be registered except
               in limited circumstances.

               Unless this Capital Security Certificate is presented by an
               authorized representative of the Depositary to Banknorth
               Capital Trust II or its agent for registration of transfer,
               exchange or payment, and any Capital Security Certificate
               issued is registered in the name of Cede & Co. or such other
               name as requested by an authorized representative of the
               Depositary (and any payment hereon is made to Cede & Co. or to
               such

                                      39
<PAGE>

               other entity as is requested by an authorized representative of
               the Depositary), ANY TRANSFER, PLEDGE OR OTHER USE HEREOF FOR
               VALUE OR OTHERWISE BY OR TO ANY PERSON IS WRONGFUL inasmuch as
               the registered owner hereof, Cede & Co., has an interest
               herein."

               Capital Securities not represented by a Global Security issued
in exchange for all or a part of a Global Security pursuant to this Section
7.12 shall be registered in such names and in such authorized denominations as
the Depositary, pursuant to instructions from its direct or indirect
participants or otherwise, shall instruct the Property Trustee. Upon execution
and authentication, the Property Trustee shall deliver such Capital Securities
not represented by a Global Security to the Persons in whose names such
definitive Capital Securities are so registered.

               At such time as all interests in Global Securities have been
redeemed, repurchased or cancelled, such Global Securities shall be, upon
receipt thereof, cancelled by the Property Trustee in accordance with standing
procedures of the Depositary. At any time prior to such cancellation, if any
interest in Global Securities is exchanged for Capital Securities not
represented by a Global Security, redeemed, cancelled or transferred to a
transferee who receives Capital Securities not represented by a Global
Security therefor or any Capital Security not represented by a Global Security
is exchanged or transferred for part of Global Securities, the principal
amount of such Global Securities shall, in accordance with the standing
procedures of the Depositary, be reduced or increased, as the case may be, and
an endorsement shall be made on such Global Securities by the Property Trustee
to reflect such reduction or increase.

               The Trust and the Property Trustee may for all purposes,
including the making of payments due on the Capital Securities, deal with the
Depositary as the authorized representative of the Holders for the purposes of
exercising the rights of Holders hereunder. The rights of the owner of any
beneficial interest in a Global Security shall be limited to those established
by law and agreements between such owners and depository participants
provided, that no such agreement shall give any rights to any Person against
the Trust or the Property Trustee without the written consent of the parties
so affected. Multiple requests and directions from and votes of the Depositary
as holder of Capital Securities in global form with respect to any particular
matter shall not be deemed inconsistent to the extent they do not represent an
amount of Capital Securities in excess of those held in the name of the
Depositary or its nominee.

               If at any time the Depositary for any Capital Securities
represented by one or more Global Securities notifies the Trust that it is
unwilling or unable to continue as Depositary for such Capital Securities or
if at any time the Depositary for such Capital Securities shall no longer be
eligible under this Section 7.12, the Trust shall appoint a successor
Depositary with respect to such Capital Securities. If a successor Depositary
for such Capital Securities is not appointed by the Trust within 90 days after
the Trust receives such notice or becomes aware of such ineligibility, the
Trusts election that such Capital Securities be represented by one or more
Global Securities shall no longer be effective and the Trust shall execute,
and the Property Trustee will authenticate and deliver, Capital Securities in
definitive registered form, in any authorized denominations, in an aggregate
liquidation amount equal to the principal amount of the Global Security or
Capital Securities representing such Capital Securities in exchange for such
Global Security or Capital Securities.

               The Trust may at any time and in its sole discretion determine
that the Capital Securities issued in the form of one or more Global
Securities shall no longer be represented by a Global Security or Capital
Securities. In such event the Trust shall execute, and the Property Trustee,
shall authenticate and deliver, Capital Securities in definitive registered
form, in any authorized denominations, in an aggregate

                                      40
<PAGE>

liquidation amount equal to the principal amount of the Global Security or
Capital Securities representing such Capital Securities, in exchange for such
Global Security or Capital Securities.

               Notwithstanding any other provisions of this Trust Agreement
(other than the provisions set forth in Section 7.9), Global Securities may
not be transferred as a whole except by the Depositary to a nominee of the
Depositary or by a nominee of the Depositary to the Depositary or another
nominee of the Depositary or by the Depositary or any such nominee to a
successor Depositary or a nominee of such successor Depositary.

               Interests of beneficial owners in a Global Security may be
transferred or exchanged for Capital Securities not represented by a Global
Security and Capital Securities not represented by a Global Security may be
transferred or exchange for Global Securities in accordance with rules of the
Depositary and the provisions of Section 7.9.

                      Common Securities or the Sponsor;

                             (iii)   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 revocation without a
                      reinstatement thereof;

                             (iv)    the entry of a decree of judicial
                      dissolution of the Sponsor or the Trust;

                             (v)     the time when all of the Securities shall
                      have been called for redemption and the amounts then due
                      shall have been paid to the Holders in accordance with
                      the terms of the Securities;

                             (vi)    at the Sponsor's election by notice and
                      direction to the Property Trustee to distribute the
                      Debentures to the Holders of the Securities in exchange
                      for all of the Securities, subject to the receipt of any
                      necessary approvals by the Federal Reserve that may then
                      be required under the applicable capital guidelines or
                      policies of the Federal Reserve; provided that the
                      Sponsor will be required to obtain an opinion of an
                      independent counsel that the distribution of the
                      Debentures will not be taxable to the Holders of the
                      Capital Securities for United States federal income tax
                      purposes; or

                             (vii)   the time when all of the Administrative
                      Trustees and the Sponsor shall have consented to
                      dissolution of the Trust provided such action is taken
                      before the issuance of any Securities.

                                      41
<PAGE>

                      (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
and liquidation of the Trust, the Trustees shall terminate the Trust by filing
a certificate of cancellation with the Secretary of State of the State of
Delaware.

                      (c)    The Sponsor must give at least 30 days written
notice to the Trustees of its election to dissolve the Trust and distribute
the Debentures pursuant to Section 8.1(a)(vi). Once the liquidation date is
fixed for any distribution of the Debentures pursuant to Section 8.1(a)(vi):

                             (i)     the Capital Securities shall no longer be
                      deemed to be outstanding;

                             (ii)    the Depositary, or its nominee, as the
                      record holder of the Capital Securities, will receive a
                      registered global certificate or certificates
                      representing the Debentures to be delivered upon the
                      distribution; and

                             (iii)   certificates representing the Capital
                      Securities not held by the Depositary or its nominee
                      will be deemed to represent the corresponding
                      Debentures. Those certificates will bear accrued and
                      unpaid interest in an amount equal to the accrued and
                      unpaid distributions on the Capital Securities until the
                      certificates are presented to the Administrative
                      Trustees or their agent for transfer or reissuance.

                      (d)    The provisions of Section 4.2 and Article 9 shall
survive the termination of the Trust.

               SECTION 8.2.   Liquidation Distribution Upon Dissolution of the
Trust.

                      (a)    In the event of any voluntary or involuntary
liquidation, dissolution, or winding-up of the Trust (each a "Liquidation"),
the Holders of the Securities on the date of the Liquidation will be entitled
to receive, out of the assets of the Trust available for distribution to
Holders of Securities after satisfaction of the Trust's liabilities to
creditors, if any, distributions in cash or other immediately available funds
in an amount equal to the aggregate of the stated liquidation amount of $25
per Security plus accumulated and unpaid Distributions thereon to the date of
payment (such amount being the "Liquidation Distribution"), unless, in
connection with a dissolution pursuant to Section 8.1(a)(vi), Debentures in an
aggregate stated principal amount equal to the aggregate stated liquidation
amount of, with an interest rate identical to the distribution rate of, and
accumulated and unpaid interest equal to 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.

                      (b)    If, upon any such Liquidation, the Liquidation
Distribution can be paid only in part because the Trust has insufficient
assets available to pay in full the aggregate Liquidation Distribution, then
the amounts payable directly by the Trust on the Securities shall be paid on a
Pro Rata basis. The Holders of the Common Securities will be entitled to
receive distributions upon any such Liquidation Pro Rata with the Holders of
the Capital Securities except that if an Indenture Event of Default has
occurred and is continuing, the Capital Securities shall have a preference
over the Common Securities with regard to such distributions as provided for
in Section 7.1(b).

               SECTION 9.1.   Liability.

                      (a)    Except as expressly set forth in this Trust
Agreement, the Guarantee and the terms of the Securities, the Sponsor:

                             (i)     shall not be personally liable for the
                      return of any portion of the capital contributions (or
                      any return thereon) of the Holders of the Securities
                      which shall be made solely from assets of the Trust; and

                             (ii)    shall not be required to pay to the Trust
                      or to any Holder of Securities any deficit upon
                      dissolution of the Trust or otherwise.

                      (b)    Pursuant to Section 3803(a) of the Business Trust
Act, the Holder of the Common 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; provided, however, the Holders 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 Capital 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 9.2.   Exculpation.

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

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

               SECTION 9.3.   Fiduciary Duty.

                      (a)    To the extent that, at law or in equity, an
Indemnified Person has duties (including fiduciary duties) and liabilities
relating thereto to the Trust or to any other Covered Person, an Indemnified
Person acting under this Trust Agreement shall not be liable to the Trust or
to another Covered Person for its good faith reliance on the provisions of
this Trust Agreement. The provisions of this Trust Agreement, to the extent
that they restrict the duties and liabilities of an Indemnified Person

                                      43
<PAGE>

otherwise existing at law or in equity (other than the duties imposed on the
Property Trustee under the Trust Indenture Act), are agreed by the parties
hereto to replace such other duties and liabilities of such Indemnified
Person.

                      (b)    Unless otherwise expressly provided herein:

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

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

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

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

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

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

               SECTION 9.4.   Indemnification.

                      (a)    The Debenture Issuer shall indemnify, to the full
extent permitted by law, any Debenture Issuer 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 Debenture Issuer Indemnified Person
against expenses (including attorney 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 Debenture Issuer Indemnified Person did not act in good
faith and in a manner

                                      44
<PAGE>

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.

                      (b)    The Debenture Issuer shall indemnify, to the full
extent permitted by law, any Debenture Issuer Indemnified Person who was or is
a party or is threatened to be made a party to any threatened, pending or
completed action or suit by or in the right of the Trust to procure a judgment
in its favor by reason of the fact that he is or was a Debenture Issuer
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 Debenture Issuer 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.

                      (c)    Any indemnification under paragraphs (a) and (b)
of this Section 9.4 (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 Debenture Issuer Indemnified Person is proper in the
circumstances because he has met the applicable standard of conduct set forth
in paragraphs (a) and (b). Such determination shall be made (1) by the
Administrative Trustees by a majority vote of a quorum consisting of such
Administrative Trustees who were not parties to such action, suit or
proceeding, (2) if such a quorum is not obtainable, or, even if obtainable, if
a quorum of disinterested Administrative Trustees so directs, by independent
legal counsel in a written opinion, or (3) by the Common Security Holder of
the Trust.

                      (d)    Expenses (including attorneys' fees) incurred by
a Debenture Issuer Indemnified Person in defending a civil, criminal,
administrative or investigative action, suit or proceeding referred to in
paragraphs (a) and (b) of this Section 9.4 shall be paid by the Debenture
Issuer in advance of the final disposition of such action, suit or proceeding
upon receipt of an undertaking by or on behalf of such Debenture Issuer
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 9.4. Notwithstanding the foregoing, no advance
shall be made by the Debenture Issuer if a determination is reasonably and
promptly made (1) by the Administrative Trustees by a majority vote of a
quorum of disinterested Administrative Trustees, (2) if such a quorum is not
obtainable, or, even if obtainable, if a quorum of disinterested
Administrative Trustees so directs, by independent legal counsel in a written
opinion or (3) the Common Security Holder of the Trust, that, based upon the
facts known to the Administrative Trustees, counsel or the Common Security
Holder at the time such determination is made, such Debenture Issuer
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 Debenture Issuer Indemnified
Person believed or had reasonable cause to believe his conduct was unlawful.
In no event shall any advance be made in instances where the Administrative
Trustees, independent legal counsel or Common Security Holder reasonably
determine that such person deliberately breached his duty to the Trust or its
Common or Capital Security Holders.

                      (e)    The indemnification and advancement of expenses
provided by, or granted pursuant to, the other paragraphs of this Section 9.4
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 Capital Security Holders of the Trust or otherwise, both as to
action in his official capacity and as to action in another

                                      45
<PAGE>

capacity while holding such office. All rights to indemnification under this
Section 9.4 shall be deemed to be provided by a contract between the Debenture
Issuer and each Debenture Issuer Indemnified Person who serves in such
capacity at any time while this Section 9.4 is in effect. Any repeal or
modification of this Section 9.4 shall not affect any rights or obligations
then existing.

                      (f)    The Debenture Issuer or the Trust may purchase
and maintain insurance on behalf of any person who is or was a Debenture
Issuer 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 9.4.

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

                      (h)    The indemnification and advancement of expenses
provided by, or granted pursuant to, this Section 9.4 shall, unless otherwise
provided when authorized or ratified, continue as to a person who has ceased
to be a Debenture Issuer Indemnified Person and shall inure to the benefit of
the heirs, executors and administrators of such a person. The obligation to
indemnify as set forth in this Section 9.4 shall survive the resignation or
removal of the Delaware Trustee or the Property Trustee or the termination of
this Trust Agreement.

               SECTION 9.5.   Outside Businesses.

               Subject to the provisions of Section 6.3, any Covered Person,
the Sponsor, the Delaware Trustee and the Property 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 activities of the
Trust, and the Trust and the Holders of Securities shall have no rights by
virtue of this Trust Agreement in and to such independent ventures or the
income or profits derived therefrom, and the pursuit of any such venture, even
if competitive with the activities of the Trust, shall not be deemed wrongful
or improper. No Covered Person, the Sponsor, the Delaware Trustee or the
Property 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 Property Trustee shall have
the right to take for its own account (individually or as a partner or
fiduciary) or to recommend to others any such particular investment or other
opportunity. Any Covered Person, the Delaware Trustee and the Property Trustee
may engage or be interested in any financial or other transaction with the
Sponsor or any Affiliate of the Sponsor, or may act as depositary for, trustee
or agent for, or act on any committee or body of holders of, securities or
other obligations of the Sponsor or its Affiliates.

               SECTION 10.1.  Fiscal Year.

                                      46
<PAGE>
               The fiscal year ("Fiscal Year") of the Trust shall be the
calendar year, or such other year as is required by the Code.

               SECTION 10.2.  Certain Accounting Matters.

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

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

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

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

               SECTION 10.3.  Banking.

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

               SECTION 10.4.  Withholding.

               The Trust and the Administrative Trustees shall comply with all
withholding requirements under United States federal, state and local law. The
Trust shall request, and the Holders shall provide to the Trust, such forms or
certificates as are necessary to establish an exemption from withholding with
respect to each Holder, and any representations and forms as shall reasonably
be requested by the Trust to assist it in determining the extent of, and in
fulfilling, its withholding obligations. The Administrative Trustees shall
file required forms with applicable jurisdictions and, unless an exemption
from withholding is properly established by a Holder, shall remit amounts
withheld with respect to the Holder to applicable jurisdictions. To the extent
that the Trust is required to withhold

                                      47
<PAGE>

and pay over any amounts to any authority with respect to distributions or
allocations to any Holder, the amount withheld shall be deemed to be a
distribution in the amount of the withholding to the Holder. In the event of
any claimed 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.

                           AMENDMENTS AND MEETINGS

               SECTION 11.1.  Amendments.

                      (a)    Except as otherwise provided in this Trust
Agreement or by any applicable terms of the Securities, this Trust Agreement
may only be amended by a written instrument approved and executed by the
Sponsor and (i) the Administrative Trustees (or, if there are more than two
Administrative Trustees, a majority of the Administrative Trustees) and (ii)
the Property Trustee if the amendment affects the rights, powers, duties,
obligations or immunities of the Property Trustee; and (iii) the Delaware
Trustee if the amendment affects the rights, powers, duties, obligations or
immunities of the Delaware Trustee.

                      (b)    No amendment shall be made, and any such
purported amendment shall be void and ineffective:

                             (i)     unless, in the case of any proposed
                      amendment, the Property Trustee shall have first
                      received an Officer's Certificate from each of the Trust
                      and the Sponsor that such amendment is permitted by, and
                      conforms to, the terms of this Trust Agreement
                      (including the terms of the Securities);

                             (ii)    unless, in the case of any proposed
                      amendment which affects the rights, powers, duties,
                      obligations or immunities of the Property Trustee, the
                      Property Trustee shall have first received:

                                     a.     an Officer's Certificate from each
                                            of the Trust and the Sponsor that
                                            such amendment is permitted by,
                                            and conforms to, the terms of this
                                            Trust Agreement (including the

                                            all conditions precedent to the
                                            execution and delivery of such
                                            amendment have been satisfied; and

                                     b.     an opinion of counsel (who may be
                                            counsel to the Sponsor or the
                                            Trust) that such amendment is
                                            permitted by, and conforms to, the
                                            terms of this Trust Agreement
                                            (including the terms of the
                                            Securities) and that all
                                            conditions precedent to the
                                            execution and delivery of such
                                            amendment have been satisfied; and

                             (iii)   to the extent the result of such
                      amendment would be to:

                                     a.     cause the Trust to be classified
                                            as other than a grantor trust for
                                            United States federal income tax
                                            purposes;

<PAGE>

                                     b.     reduce or otherwise adversely
                                            affect the powers of the Property
                                            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)    If the Trust has issued any Securities that
remain outstanding:

                             (i)     any amendment that would (a) change the

                      accordance with such amendment will not affect the
                      Trust's status as a grantor trust for United States
                      federal income tax purposes or the Trust's exemption

               SECTION 11.2.  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 Administrative 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 Trust Agreement, the terms of the Securities or the rules of any stock
exchange on which the Capital Securities are listed or admitted for trading.
The Administrative Trustees shall call a meeting of the Holders of such class
if directed to do so by the Holders of at least 10% in Liquidation Amount of
such class of Securities. Such direction shall be given by delivering to the
Administrative Trustees one or more calls in a writing stating that the
signing Holders of 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 Certificates held
by the Holders of Securities exercising the right to call a meeting and only
those Securities specified shall be counted for purposes of determining
whether the required percentage set forth in the second sentence of this
paragraph has been met.

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

                             (i)     notice of any such meeting shall be given
                      to all the Holders of Securities having a right to vote
                      thereat at least 7 days and not more than 60 days before
                      the date of such meeting. Whenever a vote, consent or
                      approval of the Holders of Securities is permitted or
                      required under this Trust Agreement or the rules of any
                      stock exchange on which the Capital 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
                      and without prior notice 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 Administrative Trustees may specify that
                      any written ballot submitted to the Security Holders for
                      the purpose of taking any action without a meeting shall
                      be returned to the Trust within the time specified by
                      the Administrative Trustees;

                             (ii)    each Holder of a Security may authorize
                      any Person to act for it by proxy on all matters in
                      which a Holder of 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 such proxy. 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 Administrative
                      Trustees or by such other Person that the Administrative
                      Trustees may designate; and

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

          (a) This Guarantee shall be held by the Guarantee Trustee on behalf of
the Trust for the benefit of the Holders of the Securities, and the Guarantee
Trustee shall not transfer this Guarantee to any Person except a Holder of

Officer of the Guarantee Trustee has occurred and is continuing, the Guarantee
Trustee shall enforce this Guarantee for the benefit of the Holders of the

Event of Default and after the curing of all Guarantee Events of Default that

Default has occurred (that has not been cured or waived pursuant to Section 2.6)
and is actually known to a Responsible Officer of the Guarantee Trustee, the
Guarantee Trustee shall exercise such of the rights and powers vested in it by
this Guarantee, and use the same degree of care and skill in its exercise
thereof, as a prudent person would exercise or use under the circumstances in
the conduct of his or her own affairs.

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

                              provisions of this Guarantee, and the Guarantee
                              Trustee shall not be liable except for the
                              performance of such duties and obligations as are
                              specifically set forth in this Guarantee, and no
                              implied covenants or obligations shall be read
                              into this Guarantee against the Guarantee Trustee;
                              and

                    (B)       in the absence of bad faith on the part of the
                              Guarantee Trustee, the Guarantee Trustee may
                              conclusively rely, as to the truth of the
                              statements and the correctness of the opinions
                              expressed therein, upon any certificates or
                              opinions furnished to the Guarantee Trustee and

                              opinions that by any provision hereof are
                              specifically required to be furnished to the

                              under a duty to examine the same to determine

                              investigate the accuracy of any matematical

          of judgment made in good faith by a Responsible Officer of the

          such judgment was made;

                    (iii) the Guarantee Trustee shall not be liable with respect
          to any action taken or omitted to be taken by it in good faith in

          Majority in Liquidation Amount of the Securities relating to the time,
          method and place of conducting any proceeding for any remedy available

          upon the Guarantee Trustee under this Guarantee; and

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

          SECTION 3.2. Certain Rights of Guarantee Trustee. (a) Subject to the
provisions of Section 3.1:

                    (i) The Guarantee Trustee may conclusively rely, and shall
          be fully protected in acting or refraining from acting upon, any
          resolution, certificate, statement, instrument, opinion, report,
          notice, request, direction, consent, order, bond, debenture, note,
          other evidence of indebtedness or other paper or document (whether in
          its original or facsimile form) believed by it to be genuine and to
          have been signed, sent or presented by the proper party or parties;

                    (ii) Any direction or act of the Guarantor contemplated by
          this Guarantee shall be sufficiently evidenced by an Officer's
          Certificate;

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

                    (iv) The Guarantee Trustee shall have no duty to see to any
          recording, filing or registration or any instrument (or any
          rerecording, refiling or re-registration thereof);

                    (v) The Guarantee Trustee may consult with counsel of its
          own selection, and the advice or opinion of such counsel with respect
          to legal matters shall be full and complete authorization and
          protection in respect of any action taken, suffered or omitted

                                       8
<PAGE>

          by it hereunder in good faith and in accordance with such advice or
          opinion. Such counsel may be counsel to the Guarantor or any of its
          Affiliates and may include any of its employees. The Guarantee Trustee
          shall have the right at any time to seek instructions concerning the
          administration of this Guarantee from any court of competent
          jurisdiction;

                    (vi) The Guarantee Trustee shall be under no obligation to
          exercise any of the rights or powers vested in it by this Guarantee at
          the request or direction of any Holder, unless such Holder shall have
          provided to the Guarantee Trustee such security and indemnity,
          reasonably satisfactory to the Guarantee Trustee, against the costs,
          expenses (including attorneys' fees and expenses and the expenses of
          the Guarantee Trustee's agents, nominees or custodians) and
          liabilities that might be incurred by it in complying with such
          request or direction, including such reasonable advances as may be
          requested by the Guarantee Trustee; provided, that nothing contained
          in this Section 3.2(a)(vi) shall be taken to relieve the Guarantee
          Trustee, upon the occurrence of a Guarantee Event of Default, of its
          obligation to exercise the rights and powers vested in it by this
          Guarantee;

                    (vii) The Guarantee Trustee shall not be bound to make any
          investigation into the facts or matters stated in any resolution,
          certificate, statement, instrument, opinion, report, notice, request,
          direction, consent, order, bond, debenture, note, other evidence of
          indebtedness or other paper or document, but the Guarantee Trustee, in
          its discretion, may make such further inquiry or investigation into
          such facts or matters as it may see fit;

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

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

                    (x) Whenever in the administration of this Guarantee, the
          Guarantee Trustee shall deem it desirable to receive instructions with
          respect to enforcing any remedy or right or taking any other action
          hereunder, the Guarantee Trustee (i) may request written instructions
          from the Holders of a Majority in Liquidation Amount of the
          Securities, (ii) may refrain from enforcing such remedy or right or
          taking such other action until such written instructions are received
          and (iii) shall be protected in conclusively relying on or acting in
          accordance with such written instructions.

          (b) No provision of this Guarantee shall be deemed to impose any duty
or obligation on the Guarantee Trustee to perform any act or acts or exercise
any right, power, duty

                                       9
<PAGE>

or obligation conferred or imposed on it in any jurisdiction in which it shall
be illegal, or in which the Guarantee Trustee shall be unqualified or
incompetent to act 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 Guarantee Trustee shall be construed to be a
duty.

                                   ARTICLE 4

                                GUARANTEE TRUSTEE

          SECTION 4.1. Guarantee Trustee; Eligibility.

          (a) There shall be at all times a Guarantee Trustee which shall:

                    (i) not be an Affiliate of the Guarantor; and

                    (ii) be a corporation organized and doing business under the
          laws of the United States of America or any state or territory thereof
          or of the District of Columbia, or a corporation or other Person
          permitted by the Securities and Exchange Commission to act as an
          institutional trustee under the Trust Indenture Act, authorized under
          such laws to exercise corporate trust powers, having a combined
          capital and surplus of at least 50 million U.S. dollars ($50,000,000),
          and subject to supervision or examination by federal, state,
          territorial or District of Columbia authority. If such corporation
          publishes reports of condition at least annually, pursuant to law or
          to the requirements of the supervising or examining authority referred
          to above, then, for the purposes of this Section 4.1(a)(ii), the
          combined capital and surplus of such corporation shall be deemed to be
          its combined capital and surplus as set forth in its most recent
          report of condition so published.

          (b) If at any time the Guarantee Trustee shall cease to be eligible to
so act under Section 4.1(a), the Guarantee Trustee shall immediately resign in
the manner and with the effect set out in Section 4.2(c) .

          (c) If the Guarantee Trustee has or shall acquire any "conflicting
interest" within the meaning of Section 310(b) of the Trust Indenture Act, the
Guarantee Trustee and Guarantor shall in all respects comply with the provisions
of Section 310(b) of the Trust Indenture Act.

          SECTION 4.2. Appointment, Removal and Resignation of Guarantee
Trustee.

          (a) Subject to Section 4.2(b), unless a Guarantee Event of Default
shall have occurred and be continuing, the Guarantee Trustee may be appointed or
removed with or without cause at any time by the Guarantor.

          (b) The Guarantee Trustee shall not be removed in accordance with
Section 4.2(a) until a Successor Guarantee Trustee has been appointed and has
accepted such appointment by written instrument executed by such Successor
Guarantee Trustee and delivered to the Guarantor.

                                       10
<PAGE>

          (c) The Guarantee Trustee appointed to office shall hold such office
until a Successor Guarantee Trustee shall have been appointed or until its
removal or resignation. The Guarantee Trustee may resign from office (without
need for prior or subsequent accounting) by an instrument in writing executed by
the Guarantee Trustee and delivered to the Guarantor, which resignation shall
not take effect until a Successor Guarantee Trustee has been appointed and has
accepted such appointment by instrument in writing executed by such Successor
Guarantee Trustee and delivered to the Guarantor and the resigning Guarantee
Trustee.

          (d) If no Successor Guarantee Trustee shall have been appointed and
accepted appointment as provided in this Section 4.2 within 60 days after
delivery to the Guarantor of an instrument of removal or resignation, the
removed or resigning Guarantee Trustee may petition, at the expense of
Guarantor, any court of competent jurisdiction for appointment of a Successor
Guarantee Trustee. Such court may thereupon, after prescribing such notice, if
any, as it may deem proper, appoint a Successor Guarantee Trustee.

          (e) No Guarantee Trustee shall be liable for the acts or omissions to
act of any Successor Guarantee Trustee.

          (f) Upon termination of this Guarantee or removal or resignation of
the Guarantee Trustee pursuant to this Section 4.2, the Guarantor shall pay to
the Guarantee Trustee all amounts owing for fees and reimbursement of expenses
which have accrued to the date of such termination, removal or resignation.

                                   ARTICLE 5

                                    GUARANTEE

          SECTION 5.1. Guarantee.

          The Guarantor irrevocably and unconditionally agrees to pay in full to
the Holders the Guarantee Payments (without duplication of amounts theretofore
paid by the Trust), as and when due, regardless of any defense, right of set-off
or counterclaim that the Trust may have or assert. The Guarantor's obligation to
make a Guarantee Payment may be satisfied by direct payment of the required
amounts by the Guarantor to the Holders or by causing the Trust to pay such
amounts to the Holders. Notwithstanding anything to the contrary herein, the
Guarantor retains all of its rights under the Indenture to extend the interest
payment period on the Debentures pursuant to Section 3.11 thereof and the
Guarantor shall not be obligated hereunder to make any Guarantee Payments during
any Extension Period (as defined in the certificate evidencing the Debentures)
with respect to the Distributions (as defined in the Trust Agreement) on the
Securities.

          SECTION 5.2. Waiver of Notice and Demand.

          The Guarantor hereby waives notice of acceptance of this Guarantee and
of any liability to which it applies or may apply, presentment, demand for
payment, any right to require a proceeding first against the Trust or any other
Person before proceeding against the Guarantor, protest, notice of nonpayment,
notice of dishonor, notice of redemption and all other notices and demands.

          SECTION 5.3. Obligations Not Affected.

          The obligations, covenants, agreements and duties of the Guarantor
under this Guarantee shall be absolute and unconditional and shall remain in
full force and effect until the entire liquidation amount of all outstanding
Securities shall have been paid and such obligation shall in no way be affected
or impaired by reason of the happening from time to time of any event, including
without limitation, the following, whether or not with notice to, or the consent
of, the Guarantor:

                    (a) The release or waiver, by operation of law or otherwise,
          of the performance or observance by the Trust of any express or
          implied agreement, covenant, term or condition relating to the
          Securities to be performed or observed by the Trust;

                    (b) The extension of time for the payment by the Trust of
          all or any portion of the Distributions, Redemption Price, Liquidation
          Distribution or any other sums payable under the terms of the
          Securities or the extension of time for the performance of any other
          obligation under, arising out of, or in connection with the Securities
          (other than an extension of time for payment of Distributions,
          Redemption Price, Liquidation Distribution or other sum payable that
          results from the extension of any interest payment period on the
          Debentures);

                    (c) Any failure, omission, delay or lack of diligence on the
          part of the Property Trustee or the Holders to enforce, assert or
          exercise any right, privilege, power or remedy conferred on the
          Property Trustee or the Holders pursuant to the terms of the
          Securities, or any action on the part of the Trust granting indulgence
          or extension of any kind;

                    (d) The voluntary or involuntary liquidation, dissolution,
          sale of any collateral, receivership, insolvency, bankruptcy,
          assignment for the benefit of creditors, reorganization, arrangement,
          composition or readjustment of debt of, or other similar proceedings
          affecting, the Trust or any of the assets of the Trust;

                    (e) Any invalidity of, or defect or deficiency in, the
          Securities;

                    (f) The settlement or compromise of any obligation
          guaranteed hereby or hereby incurred; or

                    (g) Any other circumstance whatsoever that might otherwise
          constitute a legal or equitable discharge or defense of a guarantor,
          it being the intent of this Section 5.3 that the obligations of the
          Guarantor hereunder shall be absolute and unconditional under any and
          all circumstances.

          There shall be no obligation of the Guarantee Trustee or the Holders
to give notice to, or obtain consent of the Guarantor or any other Person with
respect to the happening of any of the foregoing.

                                       12
<PAGE>

          No setoff, counterclaim, reduction or diminution of any obligation, or
any defense of any kind or nature that the Guarantor has or may have against any
Holder shall be available hereunder to the Guarantor against such Holder to
reduce the payments to it under this Guarantee.

          SECTION 5.4. Rights of Holders.

          (a) The Holders of at least a Majority in Liquidation Amount of the
Securities have the right to direct the time, method and place of conducting any
proceeding for any remedy available to the Guarantee Trustee in respect of this
Guarantee or to direct the exercise of any trust or power conferred upon the
Guarantee Trustee under this Guarantee.

          (b) If the Guarantee Trustee fails to enforce this Guarantee, then any
Holder of Securities may, subject to the subordination provisions of Section
6.2, institute a legal proceeding directly against the Guarantor to enforce the
Guarantee Trustee's rights under this Guarantee without first instituting a
legal proceeding against the Trust, the Guarantee Trustee or any other person or
entity. In addition, if the Guarantor has failed to make a Guarantee Payment, a
Holder of Securities may, subject to the subordination provisions of Section
6.2, directly institute a proceeding against the Guarantor for enforcement of
the Guarantee for such payment to the Holder of the Securities of the principal
of or interest on the Debentures on or after the respective due dates specified
in the Debentures, and the amount of the payment will be based on the Holder's
pro rata share of the amount due and owing on all of the Securities. The
Guarantor hereby waives any right or remedy to require that any action on this
Guarantee be brought first against the Trust or any other person or entity
before proceeding directly against the Guarantor.

          SECTION 5.5. Guarantee of Payment.

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

          SECTION 5.6. Subrogation.

          The Guarantor shall be subrogated to all (if any) rights of the
Holders of Securities against the Trust in respect of any amounts paid to such
Holders by the Guarantor under this Guarantee; provided, however, that the
Guarantor shall not (except to the extent required by mandatory provisions of
law) be entitled to enforce or exercise any right that it may acquire by way of
subrogation or any indemnity, reimbursement or other agreement, in all cases as
a result of payment under this Guarantee, if at the time of any such payment,
any amounts are due and unpaid under this Guarantee. If any amount shall be paid
to the Guarantor in violation of the preceding sentence, the Guarantor agrees to
hold such amount in trust for the Holders and to pay over such amount to the
Guarantee Trustee for the benefit of the Holders.

          SECTION 5.7. Independent Obligations.

          The Guarantor acknowledges that its obligations hereunder are
independent of the obligations of the Trust with respect to the Securities, and
that the Guarantor shall be liable as principal and as debtor hereunder to make
Guarantee Payments pursuant to the terms of this Guarantee notwithstanding the
occurrence of any event referred to in subsections 5.3(a) through 5.3(g),
inclusive, hereof.

                    LIMITATION OF TRANSACTIONS; SUBORDINATION

          SECTION 6.1. Limitation of Transactions.

          So long as any Securities remain outstanding, if (i) there shall have

have given notice of its election of an Extension Period as provided in the
certificate evidencing the Debentures and shall not have rescinded such notice,
or such Extension Period or any extension thereof shall be continuing, then the
Guarantor shall not, and shall not permit any subsidiary of the Guarantor, to
(x) declare or pay any dividends or distributions on, or redeem, purchase,
acquire or make a liquidation payment with respect to, any of the Guarantor's
capital stock or (y) make any payment of principal, interest or premium, if any,
on or repay, repurchase or redeem any debt securities of the Guarantor that rank
pari passu with or junior in interest to the Debentures or make any guarantee
payments with respect to any guarantee by the Guarantor of the debt securities
of any subsidiary of the Guarantor if such guarantee ranks pari passu with or
junior in interest to the Debentures (other than (a) dividends or distributions
in Common Stock of the Guarantor, (b) any declaration of a dividend in
connection with the implementation of a rights plan or the issuance of stock
under any such plan or the redemption or repurchase of any such rights pursuant
thereto, (c) payments under this Guarantee and (d) purchases of Common Stock
related to the issuance of Common Stock or rights under any of the Company's
benefits plans for its directors, officers or employees).

          SECTION 6.2. Ranking.

          This Guarantee will constitute an unsecured obligation of the
Guarantor and will rank subordinate and junior in right of payment to all Senior
and Subordinated Debt (as defined in the Indenture) of the Guarantor in the same
manner and to the same extent as set forth in Article XIII of the Indenture.

          SECTION 6.3. Subordination of Common Securities.

          If a Trust Enforcement Event has occurred and is continuing under the
Trust Agreement, the rights of the holders of the Common Securities to receive
Guarantee Payments hereunder shall be subordinated to the rights of the Holders
of the Capital Securities to receive Guarantee Payments under this Guarantee.

                                   TERMINATION

          SECTION 7.1. Termination.

          This Guarantee shall terminate upon (i) full payment of the Redemption
Price of all Securities, (ii) distribution of the Debentures to the Holders of
all the Securities or (iii) full payment of the amounts payable in accordance
with the Trust Agreement upon liquidation of the

                                       14

Trust. Notwithstanding the foregoing, this Guarantee will continue to be
effective or will be reinstated, as the case may be, if at any time any Holder
of Securities must restore payment of any sums paid under the Securities or
under this Guarantee.

                                   ARTICLE 8

          SECTION 8.1. Indemnification.

          The Guarantor agrees to indemnify each Indemnified Person (including
the Guarantee Trustee) for, and to hold each Indemnified Person harmless against
any loss, liability or expense incurred without negligence or bad faith on its
part, arising out of or in connection with the acceptance or administration of
the trust or trusts hereunder, including the reasonable costs 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
provisions of this Section 8.1 shall survive the termination of this Guarantee
or the resignation or removal of the Guarantee Trustee.

                                  MISCELLANEOUS

          SECTION 9.1. Successors and Assigns.

          All guarantees and agreements contained in this Guarantee shall bind
the successors, assigns, receivers, trustees and representatives of the
Guarantor and shall inure to the benefit of the Holders of the Securities then

the Guarantor that is permitted under Article VIII of the Indenture and pursuant
to which the successor or assignee agrees in writing to perform the Guarantor's
obligations hereunder, the Guarantor shall not assign its obligations hereunder.

          SECTION 9.2. Amendments.

          Except with respect to any changes that do not materially adversely
affect the rights of the Holders (in which case no consent of the Holders will
be required), this Guarantee may not be amended without the prior approval of
the Holders of at least a Majority in Liquidation Amount of the Securities. The
provisions of Section 11.2 of the Trust Agreement with respect to meetings of,
