SECTION 2.6 Events of Default, Waiver.

            (a) An Event of Default in respect of the Trust Securities means an
      Event of Default (as defined in the Indenture) that has occurred and is
      continuing in respect of the Debentures.

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

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

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

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

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

                                       11


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

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

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

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

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

SECTION 2.7 Event of Default, Notice.

            (a) The Property Trustee shall, within ten (10) Business Days after
      the Property Trustee has actual knowledge that an Event of Default has
      occurred, (i) transmit by mail, first-class postage prepaid, to the
      Holders of the Securities and (ii) transmit by any means provided in this
      Declaration to the Administrative Trustees and the Initial Purchaser of
      Common Securities, notices of all defaults with respect to the Securities
      actually known to a Responsible Officer of the Property Trustee, unless
      such defaults

                                       12


      have been cured or waived before the giving of such notice (the term
      "defaults" for the purposes of this Section 2.7(a) being hereby defined to
      be an Event of Default as defined in the Indenture, not including any
      periods of grace provided for therein and irrespective of the giving of
      any notice provided therein); provided that, except for a default in the
      payment of principal of or Interest (as defined in the Indenture), the
      Property Trustee shall be protected 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.

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

                  (i) a default under Sections 5.01(a) (other than the payment
            or non-payment of Liquidated Damages and Additional Sums) and
            5.01(b) of the Indenture; or

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

            (c) The Initial Purchaser of Common Securities, and the
      Administrative Trustees on behalf of the Trust, shall file annually with
      the Property Trustee a certification as to whether or not they are in
      compliance with all the conditions and covenants applicable to them under
      this Declaration.

      of the Debenture Issuer for United States federal, state and local tax
      purposes;

            (p) to take all action necessary to cause all applicable tax returns
      and tax information reports that are required to be filed with respect to
      the Trust to be duly prepared and filed by the Administrative Trustees, on
      behalf of the Trust; and

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

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

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

      Any expenses incurred by the Administrative Trustees pursuant to this
Section 3.6 shall be reimbursed by the Initial Purchaser of Common Securities.

      Any Administrative Trustee shall have the right to resign as
Administrative Trustee by delivery to the Initial Purchaser of the Common
Securities of a written notice of resignation not less than twenty (20) Business
Days prior to the time the resignation is to take effect, and such resignation
shall be effective as provided in the notice of resignation whether or not a
Successor Administrative Trustee shall have been appointed.

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

            (a) The Trust shall not, and the Trustees (including the Property
      Trustee and the Delaware Trustee) shall not, engage in any business,
      activities or transactions except as expressly provided herein or
      contemplated hereby. In particular, the Trust shall not and the
      Administrative Trustees shall cause the Trust not to:

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

                  (ii) acquire any investments or assets other than as expressly
            provided herein, or engage in any activities not authorized by this
            Declaration;

                  (iii) sell, assign, transfer, exchange, pledge, set-off or
            otherwise dispose of any of the Trust property or interests therein,
            including to the Holders, except as expressly provided herein;

                  (iv) take any action or fail to take any action that would
            cause the Trust to fail or cease to qualify as a grantor trust for
            United States federal income tax purposes, or the Debentures to be
            treated as other than indebtedness of the Debenture Issuer for
            United States federal, state and local tax purposes ;

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

                  (vi) make any loans or incur any indebtedness;

                  (vii) have any power to, or consent to any action that would
            vary the investment (within the meaning of Treasury Regulation
            Section 301.7701-4(c)) of the Trust or of the Holders;

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

                  (ix) execute mortgages, pledge, otherwise encumber any of the
            Trust's assets or take or consent to any action that would result in
            the placement of a lien on any of the Trust property; or

                  (x) revoke any action previously authorized or approved by a
            vote of the Holders of the Preferred Securities, except by
            subsequent vote of such Holders.

            (b) So long as the Property Trustee holds any Debentures, the
      Trustees may not, without obtaining the prior consent of the Holders of a
      Majority in liquidation amount of all outstanding Preferred Securities:
      (i) direct the time, method and place of conducting any proceeding for any
      remedy available to the Debenture Trustee, or execute any trust or power
      conferred on the Debenture Trustee with respect to the Debentures; (ii)
      revoke any action previously authorized or approved by a vote of the
      Holders of the Preferred Securities except by subsequent vote of such
      Holders; (iii) waive any past

                                       18


      default that is waivable under Section 5.07 of the Indenture; (iv)
      exercise any right to rescind or annul a declaration accelerating the
      maturity of the principal of the Debentures; or (v) consent to any
      amendment, modification or termination of the Indenture or the Debentures,
      where such consent shall be required; provided further, where a consent
      under the Indenture would require the consent of Holders of a Super
      Majority of the aggregate principal amount of Debentures affected thereby,
      only the Holders of the percentage of that aggregate stated liquidation
      amount of the Preferred Securities which is at least equal to the
      percentage required under the Indenture may direct the Property Trustee to
      give such consent. In addition to obtaining the approval of the Holders of
      the Preferred Securities, the Property Trustee shall be under no
      obligation to take any of the actions described in clause (iii), (iv) or
      (v) unless the Property Trustee has obtained advice of Cadwalader,
      Wickersham & Taft LLP or an Opinion of Counsel experienced in such matters
      to the effect that the Trust will not fail to be classified as a grantor
      trust for federal income tax purposes, or the Debentures as indebtedness
      of the Debenture Issuer for United States federal, state and local tax
      purposes, after taking the action into account and each Holder will be
      treated as owning an undivided beneficial interest in the Debentures. The
      foregoing provisions of this Section 3.7(b) are subject to Section 7.8
      hereof.

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 in trust for the benefit of the
      Holders. 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 5.7. 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 (in its capacity
      as such to the extent that the Person serving as Property Trustee is also
      an Administrative Trustee) 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 Trustee Account") in the name of and
            under the exclusive control of the Property Trustee on behalf of the
            Holders 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 Trustee Account and make payments or cause the
            Paying Agent to make payments to the Holders from the Property
            Trustee Account in accordance with Section 6.1. Funds in the
            Property Trustee Account shall be held uninvested until disbursed in
            accordance with this Declaration. The Property Trustee Account shall
            be an account that is maintained with a banking institution the
            rating on whose long-term unsecured indebtedness by a "nationally
            recognized statistical rating organization," as that term is defined
            for purposes of Rule 436(g)(2) under the Securities Act, is at least
            investment grade;

                                       19


                  (ii) engage in such ministerial activities as shall be
            necessary or appropriate to effect the redemption of the Trust
            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 shall be
            necessary or appropriate to effect the distribution of the
            Debentures to Holders upon the occurrence of certain events.

            (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 Declaration and the Securities.

            (e) Subject to Section 3.9(a), the Property Trustee shall take any
      Legal Action which arises out of or in connection with an Event of Default
      (of which a Responsible Officer has actual knowledge), including in
      respect of enforcing rights under the Indenture and the Debentures in
      respect of an event of default thereunder, or the Property Trustee's
      duties and obligations under this Declaration or the Trust Indenture Act.

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

                  (i) the Trust has been completely liquidated and the proceeds
            of the liquidation distributed to the Holders 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 5.7 (a
            "Successor Property Trustee").

            (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 an Event of Default actually known to a Responsible
      Officer occurs and is continuing, the Property Trustee shall, for the
      benefit of Holders, enforce its rights as holder of the Debentures subject
      to the rights of the Holders pursuant to the terms of this Declaration and
      the Securities.

            (h) The Property Trustee shall be authorized to undertake any
      actions set forth in Section 317(a) of the Trust Indenture Act.

            (i) For such time as the Property Trustee is the Paying Agent, the
      Property Trustee may authorize one or more Persons, acceptable to the
      Administrative Trustees and the Holder of Common Securities, to act as
      additional Paying Agents and 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 such additional Paying Agent may be removed by the
      Property Trustee at any time the Property Trustee remains as Paying Agent
      and a successor Paying Agent or additional Paying Agents may be (but are
      not required to be) appointed at any time by the Property Trustee while
      the Property Trustee is so acting as Paying Agent.

                                       20


            (j) 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.

      Notwithstanding anything expressed or implied to the contrary in this
Declaration or any Annex or Exhibit hereto, (i) the Property Trustee must
exercise the powers set forth in this Section 3.8 in a manner that is consistent
with the purposes and functions of the Trust set out in Section 3.3, and (ii)
the Property Trustee shall not take any action that is inconsistent with the
purposes and functions of the Trust set out in Section 3.3.

SECTION 3.9 Certain Duties and Responsibilities of the Property Trustee.

            (a) The Property Trustee, before the occurrence of any Event of
      Default and after the curing or waiving of all Events of Default that may
      have occurred, shall undertake to perform only such duties as are
      specifically set forth in this Declaration and in the Securities and no
      implied covenants or obligations shall be read into this Declaration
      against the Property Trustee. In case an Event of Default has occurred
      (that has not been cured or waived pursuant to Section 2.6) of which a
      Responsible Officer has actual knowledge, the Property Trustee shall
      exercise such of the rights and powers vested in it by this Declaration,
      and use the same degree of care and skill in their exercise, as a prudent
      person would exercise or use under the circumstances in the conduct of his
      or her own affairs. If no such Event of Default exists and the Property
      Trustee is required to decide between alternative courses of action or to
      construe ambiguous provisions in this Declaration or is unsure of the
      application of any provision of this Declaration, and the matter is not
      one on which Holders of the Preferred Securities or the Common Securities
      are entitled under this Declaration to vote, then the Property Trustee
      shall take such action as directed by the Holder of Common Securities and,
      if not directed, shall take such action as it deems advisable and in the
      best interests of the Holders of Preferred Securities and will have no
      liability, except for its own bad faith, negligence or willful misconduct.

            (b) No provision of this Declaration 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 an Event of Default and after
            the curing or waiving of all such Events of Default that may have
            occurred:

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

                                       21


                        (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 Declaration; provided, however, that 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 on their
                  face they conform to the requirements of this Declaration (but
                  need not confirm or investigate the accuracy of 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, unless it
            shall be proved that the Property Trustee was negligent in
            ascertaining the pertinent facts;

                  (iii) the Property Trustee shall not be liable with respect to
            any action taken or omitted to be taken by it in good faith in
            accordance with the direction of the Holders of not less than a
            majority in liquidation amount of the 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 Declaration;

                  (iv) no provision of this Declaration 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
            Declaration 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 Trustee 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
            Declaration 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. Money held by the Property
            Trustee need not be segregated from other funds held by it except in
            relation to the Property Trustee Account maintained by the Property
            Trustee pursuant to Section 3.8(c)(i) and except to the extent
            otherwise required by law;

                                       22


                  (viii) the Property Trustee shall not be responsible for
            monitoring the compliance by the Administrative Trustees or the
            Initial Purchaser of Common Securities with their respective duties
            under this Declaration, nor shall the Property Trustee be liable for
            any default or misconduct of the Administrative Trustees (other than
            to the extent that the Property Trustee also serves as an
            Administrative Trustee) or the Initial Purchaser of Common
            Securities; and

                  (ix) the Property Trustee shall not be deemed to have notice
            of any Event of Default unless a Responsible Officer of the Property
            Trustee has actual knowledge thereof or unless written notice of any
            event which is in fact such a default is received by the Property
            Trustee at the Corporate Trust Office of the Property Trustee, and
            such notice references the Securities and this Indenture, except as
            set forth in Section 2.7(b).

            the proper party or parties;

                  (ii) any direction or act of the Initial Purchaser of Common

                  (iii) whenever in the administration of this Declaration, 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 Officers' Certificate

            thereof;

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

                  (vii) the Property Trustee shall not be bound to make any

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

                  (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 such agent, custodian, nominee or
            attorney appointed with due care by it hereunder;

                  (ix) any action taken by the Property Trustee or its agents
            hereunder shall bind the Trust and the Holders, 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 Declaration, 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 Declaration 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 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

                                       24


            be protected in conclusively relying on or acting in accordance with
            such instructions;

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

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

                  (xiii) the rights, privileges, protections, immunities and
            benefits given to the Property Trustee, including, without
            limitation, its right to be indemnified, are extended to, and shall
            be enforceable by, the Property Trustee in each of its capacities
            hereunder, and to each agent, custodian and other Person employed to
            act hereunder;

                  (xiv) the Property Trustee may request that the Initial
            Purchaser of Common Securities deliver an Officers' Certificate
            setting forth the names of individuals and/or titles of officers
            authorized at such time to take specified actions pursuant to this
            Declaration, which Officers' Certificate may be signed by any person
            authorized to sign an Officers' Certificate, including any person
            specified as so authorized in any such certificate previously
            delivered and not superseded; and

                  (xv) The permissive rights of the Property Trustee to do
            things enumerated in this Declaration shall not be construed as
            duties.

            (b) No provision of this Declaration 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. In the exercise of
      its discretion, the Property Trustee shall take no action or fail to take
      any action that, to the actual knowledge of a Responsible Officer of the
      Property Trustee, would cause the Trust to be treated as other than a
      grantor trust for United States federal income tax purposes, or the
      Debentures as other than indebtedness of the Debenture Issuer for United
      States federal, state and local tax purposes, provided, however, that the
      Property Trustee, at the expense of the Initial Purchaser of Common
      Securities, shall consult with legal tax counsel experienced in such
      matters in the event of an Event of Default.

SECTION 3.11  Delaware Trustee.

      Notwithstanding any other provision of this Declaration other than Section
5.2, the Delaware Trustee shall not be entitled to exercise any powers, nor
shall the Delaware Trustee

                                       25


have any of the duties and responsibilities of the Administrative Trustees or
the Property Trustee described in this Declaration. Except as set forth in
Section 5.2, the Delaware Trustee shall be a Trustee for the sole and limited
purpose of fulfilling the requirements of Section 3807 of the Statutory Trust
Act. In the event the Delaware Trustee shall at any time be required to take any
action or perform any duty hereunder, the Delaware Trustee shall be entitled to
the benefits of Section 3.9(b)(ii) to (viii), inclusive, and Section 3.10. No
implied covenants or obligations shall be read into this Declaration against the
Delaware Trustee.

SECTION 3.12 Execution of Documents.

      Unless otherwise determined by the Administrative Trustees, and except as
otherwise required by the Statutory Trust Act, any one or more of the
Administrative Trustees is authorized to execute and deliver on behalf of the
Trust any documents, agreements, instruments or certificates that the
Administrative Trustees have the power and authority to execute pursuant to
Section 3.6.

SECTION 3.13 Not Responsible for Recitals or Issuance of Securities.

      The recitals contained in this Declaration and the Securities shall be
taken as the statements of the Initial Purchaser of Common Securities, 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 Declaration or the Securities.

SECTION 3.14  Duration of Trust.

      The Trust, unless terminated pursuant to the provisions of Article VIII
hereof, shall have existence up to July 1, 2042.

SECTION 3.15  Mergers.

            (a) The Trust may not merge with or into, consolidate, amalgamate,
      or be replaced by, or convey, transfer or lease all or substantially all
      of its properties and assets to any Person, except as described in Section
      3.15(b) and (c) and except with respect to the distribution of Debentures
      to Holders pursuant to Section 8.1(a)(iii) of this Declaration or Section
      3 of Annex I.

            (b) The Trust may, at the request of the Holder of Common
      Securities, with the consent of the Administrative Trustees (which consent
      will not be unreasonably withheld) and without the consent of the Holders,
      the Delaware Trustee or the Property Trustee, merge with or into,
      consolidate, amalgamate, or be replaced by, or convey, transfer or lease
      all or substantially all of its properties and assets to, a trust
      organized as such under the laws of any State; provided that:

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

                                       26


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

                        (B) substitutes for the Securities other securities
                  having substantially the same terms as the Securities (the
                  "Successor Securities") so long as the Successor Securities
                  rank the same as the Securities rank with respect to
                  Distributions and payments upon liquidation, redemption and
                  otherwise, provided, however that the Administrative Trustee
                  first obtains advice of Cadwalader, Wickersham & Taft LLP or
                  the opinion of counsel of the Trust experienced in such
                  matters, to the effect that such substitution would not vary
                  the investment (within the meaning of Treasury Regulation
                  Section 301.7701-4(c)) of the Trust or of the Holders;

                  (ii) the Holder of Common Securities expressly appoints a
            trustee of any Successor Entity that possesses the same powers and
            duties as the Property Trustee as the holder of the Debentures;

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

                  (iv) if the Preferred Securities (including any Successor
            Securities) or the Debentures are rated by any nationally recognized
            statistical rating organization prior to such transaction, such
            merger, consolidation, amalgamation, replacement, conveyance,
            transfer or lease does not cause either the Preferred Securities
            (including any Successor Securities), or the Debentures to have a
            lower rating 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 (including the holders of
            any Successor Securities) in any material respect or cause the Trust
            or the successor entity to be treated as other than a grantor trust
            for United States federal income tax purposes, or the Debentures as
            other than indebtedness of the Debenture Issuer for United States
            federal, state and local tax purposes;

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

                  (vii) prior to such merger, consolidation, amalgamation,
            replacement, conveyance, transfer or lease, each of the Holder of
            Common Securities and the Property Trustee has received advice of
            Cadwalader, Wickersham & Taft LLP or an opinion of 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,

                                       27


                  preferences and privileges of the Holders (including the
                  holders of any Successor Securities) in any material respect;

                        (B) following such merger, consolidation, amalgamation,
                  replacement, conveyance, transfer or lease, neither the Trust
                  nor the Successor Entity will be an Investment Company; and

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

                  (viii) the Holder of Common Securities or any permitted
            successor or assignee owns all of the common securities of any
            Successor Entity and guarantees the obligations of such Successor
            Entity under any Successor Securities at least to the extent
            provided by the Guarantee Agreement; and

                  (ix) there shall have been furnished to the Property Trustee
            an Officer's Certificate and an Opinion of Counsel, each to the
            effect that all conditions precedent in this Declaration to such
            transaction have been satisfied.

            (c) Notwithstanding Section 3.15(b), the Trust shall not, except
      with the consent of Holders of 100% in liquidation amount of the
      Securities, consolidate, amalgamate, merge with or into, or be replaced
      by, or convey, transfer or lease all or substantially all of its
      properties and assets to any other Person or permit any other Person 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 the Successor Entity not to be classified
      as a grantor trust for United States federal income tax purposes, or the
      Debentures to be treated as other than indebtedness of the Debenture
      Issuer for United States federal, state and local tax purposes, or would
      cause any holder of the Preferred Securities or the Successor Securities
      not to be treated as owning an undivided beneficial interest in the
      Debentures.

                                   ARTICLE IV
                     INITIAL PURCHASER OF COMMON SECURITIES

SECTION 4.1  Purchase of Common Securities by Initial Purchaser.

      At the Closing Time, the Initial Purchaser of Common Securities will
purchase all of the Common Securities then issued by the Trust, the aggregate
liquidation amount of which shall at such date equal at least three percent (3%)
of the total capital of the Trust.

SECTION 4.2 Responsibilities of the Initial Purchaser of Common Securities.

      In connection with the issue and sale of the Preferred Securities, the
Initial Purchaser of Common Securities shall have the exclusive right and
responsibility to engage in the following activities:

                                       28


            (a) to prepare for filing with the Commission the Registration
      Statement with respect to the Common Stock issuable upon conversion of the
      Preferred Securities, including any amendments thereto;

            (b) to determine the states and foreign jurisdictions in which to
      take appropriate action to qualify or register for sale all or part of the
      Preferred Securities and to do any and all such acts other than actions
      which must be taken by the Trust, and advise the Trust of actions it must
      take, and prepare for execution and filing any documents to be executed
      and filed by the Trust, as the Initial Purchaser of Common Securities
      deems necessary or advisable in order to comply with the applicable laws
      of any such states and foreign jurisdictions;

            (c) if so determined by the Initial Purchaser of Common Securities,
      to prepare for filing by the Trust an application to PORTAL;

            (d) to negotiate the terms of the Purchase Agreement, the
      Registration Rights Agreement and other related agreements providing for
      the sale of the Preferred Securities; and

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

SECTION 4.3  Right to Proceed.

      The Initial Purchaser of Common Securities acknowledges the rights of the
Holders of Preferred Securities, in the event that a failure of the Trust to pay
Distributions on the Preferred Securities is attributable to the failure of the
Debenture Issuer to pay Interest or principal on the Debentures and the rights
of the Holders to institute a proceeding directly against the Debenture Issuer
for enforcement of its payment obligations on the Debentures.

SECTION 4.4 Right to Terminate Trust.

      The Holder of Common Securities will have the right at any time to
terminate the Trust and, after satisfaction of liabilities to creditors of the
Trust as required by applicable law, to cause the Debentures to be distributed
to the Holders of the Trust Securities in liquidation of the Trust.

SECTION 4.5 Obligations of the Initial Purchaser.

      The Initial Purchaser of Common Securities agrees to take the position,
for United States federal and state income and franchise tax purposes, that (i)
the Trust is a grantor trust and not a partnership or any association taxable as
a corporation, and (ii) the Debentures constitute indebtedness of the Debenture
Issuer.

                                       29


                                    ARTICLE V
                                    TRUSTEES

SECTION 5.1  Number of Trustees: Appointment of Co-Trustee.

      The number of Trustees initially shall be five (5), consisting of three
(3) Administrative Trustees, the Delaware Trustee and the Property Trustee, and:

            (a) at any time before the issuance of any Securities, the Initial
      Purchaser of Common Securities may, by written instrument, increase or
      decrease the number of Trustees; and

            (b) after the issuance of any Securities, the number of Trustees may
      be increased or decreased by vote of the Holders of a Majority in
      liquidation amount of the Common Securities voting as a class at a meeting
      of the Holders of the Common Securities;

provided, however, that, the number of Trustees shall in no event be less than
three (3); provided further that (1) one Trustee, in the case of a natural
person, shall be a person who is a resident of the State of Delaware or that, if
not a natural person, is an entity which has its principal place of business in
the State of Delaware (the "Delaware Trustee"); (2) there shall be at least one
Trustee to perform ministerial functions who may be an employee or officer of,
or is affiliated with, the Initial Purchaser of Common Securities (an
"Administrative Trustee"); and (3) one Trustee shall be the Property Trustee for
so long as this Declaration is required to qualify as an indenture under the
Trust Indenture Act, and such Trustee may also serve as Delaware Trustee if it
meets the applicable requirements. The term "Administrative Trustees" as used
herein shall include all Trustees who are Administrative Trustees of the Trust,
or if there shall be only one Administrative Trustee, then such term shall be
deemed to refer to such Administrative Trustee. Notwithstanding the above,
unless an Event of Default shall have occurred and be continuing, at any time or
times, for the purpose of meeting the legal requirements of the Trust Indenture
Act or of any jurisdiction in which any part of the Trust's property may at the
time be located, the Holders of a Majority in liquidation amount of the Common
Securities acting as a class at a meeting of the Holders of the Common
Securities, and the Administrative Trustees shall have power to appoint one or
more Persons either to act as a co-trustee, jointly with the Property Trustee,
of all or any part of the Trust's property, or to act as separate trustee of any
such property, in either case with such powers as may be provided in the
instrument of appointment, and to vest in such Person or Persons in such
capacity any property, title, right or power deemed necessary or desirable,
subject to the provisions of this Declaration. In case an Event of Default has
occurred and is continuing, the Property Trustee alone shall have power to make
any such appointment of a co-trustee.

SECTION 5.2  Delaware Trustee.

      If required by the Statutory Trust Act, the Delaware Trustee shall be:

            (a) a natural person who is a resident of the State of Delaware; or

                                       30


            (b) if not a natural person, an entity which has its principal place
      of business in the State of Delaware, and otherwise meets the requirements
      of applicable law,

provided that, if the Property Trustee has its principal place of business in
the State of Delaware and otherwise meets the requirements of applicable law,
then the Property Trustee shall also be the Delaware Trustee and Section 3.11
shall have no application.

SECTION 5.3  Property Trustee; Eligibility.

            (a) There shall at all times be one Trustee (the "Property Trustee")
      which shall act as Property Trustee which shall:

                  (i) not be an Affiliate of the Initial Purchaser of Common
            Securities; and

                  (ii) be a corporation or national banking association
            organized and doing business under the laws of the United States of
            America or any State or Territory thereof or of the District of

            powers, having a combined capital and surplus of at least fifty (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 or national banking association
            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 5.3(a)(ii),
            the combined capital and surplus of such Person shall be deemed to
            be its combined capital and surplus as set forth in its most recent
            report of condition so published.

            (b) If at any time the Property Trustee shall cease to be eligible
      to so act under Section 5.3(a), the Property Trustee shall immediately
      resign in the manner and with the effect set forth in Section 5.7(c).

            (c) If the Property Trustee has or shall acquire any "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 Agreement shall be deemed to be specifically
      described in this Declaration for purposes of clause (i) of the first
      provision contained in Section 310(b) of the Trust Indenture Act.

            except if a meeting of the Administrative Trustees is called with
            respect to any matter over which the Administrative Trustees have
            power to act, any power of the Administrative Trustees may be
            exercised by, or with the consent of, any one such Administrative
            Trustee; and

                  (ii) unless otherwise determined by the Administrative

            Act or applicable law, any Administrative Trustee is authorized to
            execute on behalf of the Trust any documents which the

            Trust to execute pursuant to Section 3.6, provided, that, any
            Registration Statement referred to in Section 3.6, including any
            amendments thereto, shall, to the extent required by applicable law,
            be signed by all of the Administrative Trustees.

                        (B) if an Event of Default shall have occurred and be
                  continuing, in which event the Property Trustee or the
                  Delaware Trustee may be removed only by the vote of Holders of
                  a Majority in liquidation amount of the Preferred Securities
                  voting as a class at a meeting of Holders of the Preferred

      Trustee has been appointed and has accepted such appointment by written
      instrument executed by such Successor Property Trustee and delivered to
      the removed Property Trustee, the remaining Trustees and the Initial
      Purchaser of Common Securities; and

                  (ii) The Trustee that acts as Delaware Trustee shall not be
            removed in accordance with Section 5.7(a) until a successor Trustee
            possessing the qualifications to act as Delaware Trustee under
            Sections 5.2 and 5.4 (a "Successor Delaware Trustee") has been
            appointed and has accepted such appointment by written instrument

                                       33


            the removed Property Trustee, the remaining Trustees and the Initial
            Purchaser of Common Securities.

                  (iii) The Administrative Trustee shall not be removed in
            accordance with Section 5.7(a) unless and until at least one other
            Trustee shall have been appointed and shall have accepted such
            appointment to act as an Administrative Trustee hereunder (a
            "Successor Administrative Trustee") by written instrument executed
            by such Successor Administrative Trustee and delivered to the
            Initial Purchaser of Common Securities.

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

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

                        (A) except as otherwise provided in Section 3.6, until a
                  Successor Property Trustee or Successor Administrative
                  Trustee, as the case may be, has been appointed and has
                  accepted such appointment by instrument executed by such
                  Successor Property Trustee or Successor Administrative
                  Trustee, as the case may be, and delivered to the Trust, the
                  Delaware Trustee, the Initial Purchaser of Common Securities,
                  the resigning Property Trustee and/or the resigning
                  Administrative Trustee, as applicable; or

                        (B) until the assets of the Trust have been completely
                  liquidated and the proceeds thereof distributed to the
                  Holders; 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 Property Trustee, the Initial Purchaser of Common
            Securities and the resigning Delaware Trustee.

            (d) The Holders of the Common Securities shall use their best
      efforts to promptly appoint a Successor Delaware Trustee or Successor
      Property Trustee, as the case may be, if the Property Trustee or the
      Delaware Trustee delivers an instrument of resignation in accordance with
      this Section 5.7.

            (e) If no Successor Property Trustee or Successor Delaware Trustee
      shall have been appointed and accepted appointment as provided in this
      Section 5.7 within sixty (60) days after delivery of an instrument of
      resignation or removal, the Property Trustee or Delaware Trustee resigning
      or being removed, as applicable, at the expense of the Initial Purchaser
      of Common Securities, may petition any court of competent

                                       34


      jurisdiction for appointment of a Successor Property Trustee or Successor
      Delaware Trustee. Such court may thereupon, after prescribing such notice,
      if any, as it may deem proper and prescribe, appoint a Successor Property
      Trustee or Successor Delaware Trustee, as the case may be.

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

            (g) At the time of resignation or removal of the Property Trustee,
      the Delaware Trustee or Administrative Trustee, the Debenture Issuer shall
      pay to such Trustee any amounts that may be owed to such Trustee pursuant
      to Section 10.4.

SECTION 5.8  Vacancies Among Trustees.

      If a Trustee ceases to hold office for any reason and the number of
Trustees is not reduced pursuant to Section 5.1, or if the number of Trustees is
increased pursuant to Section 5.1, a vacancy shall occur. A resolution
certifying the existence of such vacancy by an Administrative Trustee shall be
conclusive evidence of the existence of such vacancy. The vacancy shall be
filled with a Trustee appointed in accordance with Section 5.7.

SECTION 5.9  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 dissolve, terminate or annul 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 5.7, 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 Declaration.

SECTION 5.10  Meetings.

      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 24 hours before such meeting. Notice of
any telephonic meetings of the Administrative Trustees or any committee thereof
shall be hand delivered or otherwise delivered in writing (including by
facsimile, with a hard copy by overnight courier) not less than 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 Declaration, any action of the Administrative
Trustees may be taken at a meeting by vote of a majority of the Administrative
Trustees present

                                       35


(whether in person or by telephone), provided that a Quorum is
present, or without a meeting 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 5.11  Delegation of Power.

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

            (b) The 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 this
      Declaration.

SECTION 5.12  Merger, Conversion, Consolidation or Succession to Business.

      If the Property Trustee, the Delaware Trustee or any Administrative
Trustee that is not a natural person, as the case may be, is merged, converted
or consolidated into another Person, or any such Trustee is a party to a merger,
conversion or consolidation that results in a new entity, or any Person succeeds
to all or substantially all the corporate trust business of the Property
Trustee, the Delaware Trustee or any Administrative Trustee that is not a
natural person, as the case may be, the new entity shall be the successor of the
Property Trustee, the Delaware Trustee or the Administrative Trustee, as the
case may be, hereunder, without the execution or filing of any paper or any
further act on the part of any of the parties hereto, provided such Person shall
be otherwise qualified and eligible.

                                  DISTRIBUTIONS

SECTION 6.1  Distributions

      Holders shall receive Distributions in accordance with the applicable
terms of the relevant Holder's Securities. If and to the extent that the
Debenture Issuer makes a payment of Interest (including Liquidated Damages and
Additional Sums) or principal on the Debentures held by the Property Trustee, or
other amounts payable thereunder with respect to overdue installments of
principal or Interest, or any other payments (including, without limitation,
make-whole payments, if any) with respect to 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, to make a distribution (a "Distribution") of the Payment Amount to
Holders.

                                   ARTICLE VII
                             ISSUANCE OF SECURITIES

SECTION 7.1  General Provisions Regarding Securities.

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

            (b) 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.

            (c) Upon issuance of the Securities as provided in this Declaration,
      the Securities so issued shall be deemed to be validly issued, fully paid
      and non-assessable, and each Holder thereof shall be entitled to the
      benefits provided by this Declaration.

            (d) Each Holder or beneficial owner of any Preferred Security
      agrees, for United States federal and state income and franchise tax
      purposes:

                     (i) to treat the Trust as a grantor trust and not as a
              partnership or an association taxable as a corporation;

                     (ii) to the treatment of such Holder or beneficial owner as
              a grantor owner of an undivided interest in the Debentures; and

                     (iii) to treat the Debentures as indebtedness of the
              Initial Purchaser of Common Securities;

            (e) If contrary to the parties' intent, the Trust is not treated as
      a grantor trust for United States federal income tax purposes, the parties
      intend that (1) the Trust will be treated as a partnership for United
      States federal income tax purposes, (2) all income, gain, losses and
      deductions for each taxable year will be allocated among the Holders in a
      manner consistent with Section 704 of the Code and the regulations
      thereunder, so as to cause the capital accounts of each Holder to equal
      the amount that each Holder would be entitled to receive if the Trust were
      to liquidate and distribute all of its income and assets in accordance
      with the Holders' interests as reflected in the Declaration, and (3) no
      allocation to the Holders of the Preferred Securities will be
      characterized as a guaranteed payment under Section 707(c) of the Code.

            (f) On each day from the date on which the Holder acquires the
      Preferred Securities through and including the date on which the Holder
      disposes of its interests in such Preferred Securities: (a) such Holder is
      not an employee benefit plan or other similar retirement plan or
      arrangement, whether or not subject to the Employee

                                       37


      Retirement Income Security Act of 1974, as amended ("ERISA") or Section
      4975 of the Code (or any similar laws or regulations), or an entity whose
      underlying assets are considered to include the assets of any such plans
      and arrangements (each, a "Plan") and no part of the assets to be used by
      such Holder to acquire and/or hold the Preferred Securities or any
      interest therein constitutes plan assets of any Plan or (b) the
      acquisition, holding, and, if applicable, conversion of the Preferred
      Securities by such Holder will not constitute a non-exempt prohibited
      transaction under the Title I of ERISA or Section 4975 of the Code or a
      violation under any other applicable laws and regulations that are similar
      to the provisions of Title I of ERISA or Section 4975 of the Code; and

            (g) Each Preferred Security Certificate will bear the following
      legend:

            BY ITS ACQUISITION OF THIS CERTIFICATE THE HOLDER REPRESENTS THAT
      EITHER (I) IT IS NOT AN EMPLOYEE BENEFIT PLAN OR OTHER SIMILAR RETIREMENT
      PLAN OR ARRANGEMENT, WHETHER OR NOT SUBJECT TO THE EMPLOYEE RETIREMENT
      INCOME SECURITY ACT OF 1974, AS AMENDED ("ERISA") OR SECTION 4975 OF THE
      INTERNAL REVENUE CODE OF 1986, AS AMENDED (THE "CODE") (OR ANY SIMILAR
      LAWS OR REGULATIONS) OR AN ENTITY WHOSE UNDERLYING ASSETS ARE CONSIDERED
      TO INCLUDE THE ASSETS OF ANY SUCH PLANS AND ARRANGEMENTS (EACH, A "PLAN")
      AND NO PART OF THE ASSETS TO BE USED BY THE HOLDER TO ACQUIRE AND/OR HOLD
      THIS CERTIFICATE OR ANY INTEREST THEREIN CONSTITUTES PLAN ASSETS OF ANY
      PLAN OR (II) THE ACQUISITION, HOLDING, AND, IF APPLICABLE, CONVERSION OF
      THIS CERTIFICATE WILL NOT CONSTITUTE A NON-EXEMPT PROHIBITED TRANSACTION
      UNDER THE TITLE I OF ERISA OR SECTION 4975 OF THE CODE OR A VIOLATION
      UNDER ANY OTHER APPLICABLE LAWS AND REGULATIONS THAT ARE SIMILAR TO THE
      PROVISIONS OF TITLE I OF ERISA OR SECTION 4975 OF THE CODE.

            (h) Each Preferred Security Certificate and Common Security
      Certificate will bear the following legend:

      "THIS SECURITY AND THE SHARES OF COMMON STOCK ISSUABLE UPON CONVERSION OF

                                       39


      MEANING OF SECTION 856(a)(6) AND SECTION 856(h) OF THE INTERNAL REVENUE
      CODE, AND SHALL BE CONSTRUED CONSISTENT WITH THIS INTENT."

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

SECTION 7.2 Execution and Authentication.

            (a) The Securities shall be signed on behalf of the Trust by an
      Administrative Trustee. In case any Administrative Trustee of the Trust
      who shall have signed any of the Securities shall cease to be such
      Administrative Trustee before the Securities so signed shall be delivered
      by the Trust, such Securities nevertheless may be delivered as though the
      person who signed such Securities had not ceased to be such Administrative
      Trustee; and any Securities may be signed on behalf of the Trust by such
      persons who, at the actual date of execution of such Security, shall be
      the Administrative Trustees of the Trust, although at the date of the
      execution and delivery of the Declaration any such person was not an
      Administrative Trustee.

            (b) One Administrative Trustee shall sign the Securities for the
      Trust by manual or facsimile signature.

      A Preferred Security shall not be valid until authenticated by the manual
or facsimile signature of an authorized signatory of the Property Trustee. The
signature shall be conclusive evidence that the Preferred Security has been
authenticated under this Declaration.

      Upon a written order of the Trust signed by the Initial Holder of Common
Securities, the Property Trustee shall authenticate the Preferred Securities for
original issue. The aggregate number of Preferred Securities outstanding at any
time shall not exceed the number set forth in the Terms in Annex I hereto except
as provided in Section 7.6.

      The Property Trustee may appoint an authenticating agent acceptable to the
Trust to authenticate Preferred Securities. An authenticating agent may
authenticate Preferred Securities whenever the Property Trustee may do so. Each
reference in this Declaration 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 Initial Purchaser of Common Securities or an

SECTION 7.3  Form and Dating.

      The Preferred Securities shall be evidenced by one or more certificates
substantially in the form of Exhibit A-1 and the Common Securities shall be
evidenced by one or more certificates substantially in the form of Exhibit A-2,
each of which is hereby incorporated in and expressly made a part of this
Declaration. The Property Trustee's certificate of authentication shall be
substantially in the form set forth in Exhibit A-1. Certificates representing
the Securities

                                       40


may 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. The Securities may have letters, CUSIP or other
numbers, notations or other marks of identification or designation and such
legends or endorsements required by law, stock exchange rule, agreements to
which the Trust is subject, if any, or usage (provided that any such notation,
legend or endorsement is in a form acceptable to the Trust). The Trust at the
direction of the Initial Purchaser of Common Securities shall furnish any such
legend not contained in Exhibit A-1 to the Property Trustee in writing. Each
Security shall be dated the date of its authentication. The terms and provisions
of the Securities set forth in Annex I and the forms of Securities set forth in
Exhibits A-1 and A-2 are part of the terms of this Declaration and to the extent
applicable, the Property Trustee and the Initial Purchaser of Common Securities,
by their execution and delivery of this Declaration, expressly agree to such
terms and provisions and to be bound thereby.

      The Preferred Securities are being offered and sold by the Trust pursuant
to a Purchase Agreement relating to the Preferred Securities, dated June 28,
2007, among the Trust, the Initial Purchaser of Common Securities and the
Purchasers named therein (the "Purchase Agreement").

            (a) Global Securities. The Preferred Securities shall initially be
      issued in the form of one or more permanent Global Certificates in
      definitive, fully registered form without distribution coupons as set
      forth in Exhibit A-1 hereto (a "Global Preferred Security"), which shall
      be deposited on behalf of the purchasers of the Global Preferred
      Securities represented thereby with the Property Trustee, at its Corporate
      Trust Office, as custodian for the Clearing Agency, and registered in the
      name of the Clearing Agency or a nominee of the Clearing Agency, duly
      executed by the Trust and authenticated by the Property Trustee as
      hereinafter provided. The number of Preferred Securities represented by a
      Global Preferred Security may from time to time be increased or decreased
      by adjustments made on the records of the Property Trustee and the
      Clearing Agency or its nominee as hereinafter provided. Except as provided
      in Section 9.2(g), owners of beneficial interests in a Global Preferred
      Security will not be entitled to receive Certificated Preferred
      Securities.

            (b) Book-Entry Provisions. This Section 7.3(b) shall apply only to
      the Global Preferred Securities and such other Preferred Securities in
      global form as may be authorized by the Trust to be deposited with or on
      behalf of the Clearing Agency.

            An Administrative Trustee shall execute and the Property Trustee
      shall, in accordance with this Section 7.3, authenticate and make
      available for delivery initially one or more Global Preferred Securities
      that (i) shall be registered in the name of Cede & Co. or other nominee of
      a Clearing Agency and (ii) shall be delivered by the Property Trustee to
      such Clearing Agency or pursuant to such Clearing Agency's written
      instructions or, if no such written instructions are received by the
      Property Trustee, held by the Property Trustee as custodian for the
      Clearing Agency.

            Clearing Agency Participants shall have no rights under this
      Declaration with respect to any Global Preferred Security held on their
      behalf by the Clearing Agency or by the Property Trustee as the custodian
      of the Clearing Agency or under such Global

                                       41


      Preferred Security, and the Clearing Agency may be treated by the Trust,
      the Property Trustee and any agent of the Trust or the Property Trustee as
      the absolute owner of such Global Preferred Security for all purposes
      whatsoever. Notwithstanding the foregoing, nothing herein shall prevent
      the Trust, the Property Trustee or any agent of the Trust or the Property
      Trustee from giving effect to any written certification, proxy or other
      authorization furnished by the Clearing Agency or impair, as between the
      Clearing Agency and its Participants, the operation of customary practices
      of such Clearing Agency governing the exercise of the rights of a holder
      of a beneficial interest in any Global Preferred Security.

            (c) Certificated Preferred Securities. Owners of definitive, fully
      registered certificated Preferred Securities ("Certificated Preferred
      Securities") will not be entitled to receive beneficial interests in a
      Global Preferred Security.

            (d) Authorized Denominations. The Preferred Securities are issuable
      only in denominations of $1,000.00 and any integral multiple thereof.

SECTION 7.4  Registrar, Paying Agent, Conversion Agent and Exchange Agent.

      The Trust shall maintain (i) an office or agency where Preferred
Securities may be presented for registration of transfer ("Registrar"), (ii) an
office or agency where Preferred Securities may be presented for payment
("Paying Agent"), (iii) an office or agency where Preferred Securities may be
presented for conversion ("Conversion Agent") and (iv) an office or agency where
Preferred Securities may be presented for repurchase upon the occurrence of a
Change In Control or a Termination of Trading ("Exchange Agent"). The Registrar
shall keep a register of the Preferred Securities and of their transfer. The
Administrative Trustees may appoint the Registrar, the Paying Agent, the
Conversion Agent and the Exchange Agent and may appoint one or more
co-Registrars, one or more additional paying agents, one or more additional
conversion agents and one or more additional exchange agents in such other
locations as it shall determine. The term "Registrar" includes any additional
registrar, "Paying Agent" includes any additional paying agent, "Conversion
Agent" includes any additional conversion agent and "Exchange Agent" includes
any additional exchange agent. The Administrative Trustees may change any
Registrar, Paying Agent, Conversion Agent or Exchange Agent without prior notice
to any Holder. Any Paying Agent, Conversion Agent or Exchange Agent may be
removed by the Administrative Trustees at any time and a successor Paying Agent
or Conversion Agent or Exchange Agent or additional Paying Agent, Conversion
Agent or Exchange Agent may be appointed at any time by the Administrative
Trustees. The Paying Agent, the Conversion Agent and the Exchange Agent may
resign upon thirty (30) days written notice to the Administrative Trustees. The
Administrative Trustees shall notify the Property Trustee of the name and
address of any Agent not a party to this Declaration. If the Administrative
Trustees fail to appoint or maintain another entity as Registrar, Paying Agent,
Conversion Agent or Exchange Agent, the Property Trustee shall act as such. The
Trust shall act as Paying Agent and Registrar for the Common Securities.

      The Trust initially appoints the Property Trustee, at its Corporate Trust
Office, as Registrar, Paying Agent, Conversion Agent and Exchange Agent for the
Preferred Securities.

                                       42


SECTION 7.5  Paying Agent to Hold Money in Trust.

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

SECTION 7.6 Replacement Securities.

      If a Holder claims that a Security owned by it has been lost, destroyed or
wrongfully taken or if such Security is mutilated and is surrendered to the
Trust or in the case of the Preferred Securities to the Property Trustee, the
Trust shall issue and the Property Trustee shall, upon written order of the
Trust, authenticate a replacement Security if the Property Trustee's and the
Trust's requirements, as the case may be, are met. An indemnity bond must be
provided by the Holder which, in the judgment of the Property Trustee and the
Initial Purchaser of Common Securities, is sufficient to protect the Trustees,
the Initial Purchaser of Common Securities, the Trust or any authenticating
agent from any loss which any of them may suffer if a Security is replaced. The
Trust may charge such Holder for its expenses in replacing a Security.

      No service charge shall be made to a Holder for any registration or
transfer or exchange, but the Initial Purchaser of Common Securities, on behalf
of the Trust, may require payment of a sum sufficient to cover any transfer tax
or similar governmental charge payable in connection therewith.

SECTION 7.7  Outstanding Preferred Securities.

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

      If a Preferred Security is replaced pursuant to Section 7.6 hereof, it
ceases to be outstanding unless the Property Trustee receives proof satisfactory
to it that the replaced Preferred Security is held by a bona fide purchaser.

      If Preferred Securities are considered paid in accordance with the terms
of this Declaration, including upon conversion thereof into Common Stock, they
cease to be outstanding and Distributions on them shall cease to accumulate,
subject, in the case of Preferred Securities which have been converted, to the
rights of Holders as of a record date with respect to the Distribution to be
paid on the applicable Distribution Payment Date.

                                       43


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

SECTION 7.8 Preferred Securities in Treasury.

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

SECTION 7.9  Temporary Securities.

      Until definitive Securities are ready for delivery, the Trust may prepare
and, in the case of the Preferred Securities, the Property Trustee shall, upon
receipt of a written order of the Trust, authenticate temporary Securities.
Temporary Securities shall be substantially in the form of definitive Securities
but may have variations that the Trust considers appropriate for temporary
Securities. Without unreasonable delay, the Trust shall prepare and, in the case
of the Preferred Securities, the Property Trustee shall, upon receipt of a
written order of the Trust, authenticate, definitive Securities in exchange for
temporary Securities. Until so exchanged, the temporary Securities shall in all
respects be entitled to the same benefits under this Declaration as definitive
Securities.

SECTION 7.10  Cancellation.

      The Trust at any time may deliver Preferred Securities to the Property
Trustee for cancellation. The Registrar, Paying Agent, Conversion Agent and
Exchange Agent shall forward to the Property Trustee any Preferred Securities
surrendered to them for registration of transfer, redemption, conversion,
exchange or payment (including payment following a Change in Control or a
Termination of Trading). The Property Trustee shall promptly cancel all
Preferred Securities, surrendered for registration of transfer, redemption,
conversion, exchange, payment, replacement or cancellation and shall dispose of
cancelled Preferred Securities in accordance with its customary procedures
unless the Trust otherwise directs. The Trust may not issue new Preferred
Securities to replace Preferred Securities that it has paid or that have been
delivered to the Property Trustee for cancellation or that any Holder has
converted or presented for repayment following a Change in Control or a
Termination of Trading.

SECTION 7.11  CUSIP Numbers.

      The Trust in issuing the Preferred Securities may use "CUSIP" numbers (if
then generally in use), and, if so, the Property Trustee shall use "CUSIP"
numbers in notices of redemption as a convenience to Holders of Preferred
Securities; provided that any such notice may state that no representation is
made as to the correctness of such numbers either as printed on the Preferred
Securities or as contained in any notice of a redemption and that reliance may
be placed only on the other identification numbers printed on the Preferred
Securities, and any such

                                       44


redemption shall not be affected by any defect in or omission of such numbers.
The Initial Purchaser of Common Securities will promptly notify the Property
Trustee of any change in the CUSIP numbers.

SECTION 7.12  Payment.

      Payments in respect of the Global Preferred Securities shall be made to
the Clearing Agency or its nominee, and the Clearing Agency shall credit the
relevant accounts at the Clearing Agency. Payments on the Securities issued in
certificated form may be made at the option of the Trust (i) by check mailed to
the Holder at such address set forth on the books and records of the Trust or
the Registrar or (ii) by transfer to an account maintained by the Holder
entitled thereto, provided that proper transfer instructions have been received
in writing by the relevant record date.

                              TERMINATION OF TRUST

SECTION 8.1  Termination of Trust.

            (a) The Trust shall automatically terminate:

                  (i) upon the bankruptcy of the Debenture Issuer;

                  (ii) upon the filing of a certificate of dissolution or
            liquidation or its equivalent with respect to the Debenture Issuer;

                  (iii) following the distribution of all of the Debentures to
            the Holders, provided that, the Property Trustee has received
            written notice from the Holder of Common Securities directing the
            Property Trustee to terminate the Trust (which direction is
            optional, and except as otherwise expressly provided below, within
            the discretion of the Holder of Common Securities);

                  (iv) upon the entry of a decree of judicial dissolution of the
            Trust by a court of competent jurisdiction;

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

                  (vi) upon the redemption or repayment of the Debentures at
            Maturity;

                  (vii) the expiration of the term of the Trust provided in
            Section 3.14;

                  (viii) when all of the Preferred Securities shall have been
            converted into shares of Common Stock of the Initial Purchaser of
            Common Securities; or

                  (ix) when all Preferred Securities shall have been presented
            for repurchase following a Change in Control or a Termination of
            Trading and a Like

                                       45


            Amount of Debentures shall have been repurchased upon such Change in
            Control or a Termination of Trading by the Debenture Issuer.

            (b) As soon as is practicable upon completion of winding up of the
      Trust following the occurrence of an event referred to in Section 8.1(a),
      the Administrative Trustees shall file a certificate of cancellation with
      the Secretary of State of the State of Delaware in accordance with the
      Statutory Trust Act.

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

                                   ARTICLE IX
                              TRANSFER OF INTERESTS

SECTION 9.1  Transfer of Securities.

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

            (b) For so long as the Trust Securities remain outstanding, the
      Initial Purchaser of Common Securities will covenant (i) to maintain,
      directly or indirectly, 100% ownership of the Common Securities, provided
      that any successor of the Initial Purchaser of Common Securities permitted
      hereunder or under the Indenture may succeed to the Initial Purchaser's of
      Common Securities ownership of such Common Securities, (ii) not to cause,
      as Initial Purchaser of Common Securities of the Trust, or to permit, as
      Holder of the Common Securities, the dissolution, winding-up, liquidation
      or termination of the Trust, except in connection with a distribution of
      the Debentures as provided in the Declaration, the redemption or
      repurchase of all of the Trust Securities and in connection with certain
      mergers, consolidations or amalgamations in each case, as permitted by
      this Declaration, (iii) to use commercially reasonable efforts to cause
      the Trust to remain a statutory trust, (iv) to use its reasonable efforts,
      consistent with the terms and provisions of this Declaration, to cause the
      Trust to remain classified as a grantor trust and not as an association
      taxable as a corporation for United States federal income tax purposes,
      (v) to treat the Debentures as indebtedness of the Initial Purchaser of
      Common Securities; and (vi) to use its reasonable efforts to ensure that
      the Trust will not be an "investment company" for purposes of the
      Investment Company Act of 1940.

            (c) The Administrative Trustees shall provide for the registration
      of Securities and of the transfer of Securities, which will be effected
      without charge but only upon payment (with such indemnity as the
      Administrative Trustees may require) in respect of any tax or other
      governmental charges that may be imposed in connection with any transfer
      or exchange. Upon surrender for registration of transfer of any
      Securities, the Administrative Trustees shall cause one or more new
      Securities to be issued in the name of the designated transferee or
      transferees. Every Security surrendered for registration of transfer shall
      be accompanied by a written instrument of transfer in form satisfactory to

                                       46


      the Administrative Trustees duly executed by the Holder or such
      Holder's attorney duly authorized in writing. Each Security surrendered
      for registration of transfer shall be canceled by the Property Trustee (in
      the case of Preferred Securities) or the Trust (in the case of Common
      Securities). A transferee of a Security shall be entitled to the rights
      and subject to the obligations of a Holder hereunder upon the receipt by
      such transferee of a Security. By acceptance of a Security, each
      transferee shall be deemed to have agreed to be bound by this Declaration.

SECTION 9.2 Transfer Procedures and Restrictions.

            (a) General. Each Preferred Security that bears or is required to
      bear the Restricted Securities Legend set forth in Section 9.2(c) is
      referred to herein as a "Restricted Preferred Security" and shall be
      subject to the restrictions on transfer set forth in Section 9.2(c).
      Subject to Section 9.2(c), if Preferred Securities are issued upon the
      transfer, exchange or replacement of Preferred Securities bearing the
      Restricted Securities Legend, or if a request is made to remove such
      Restricted Securities Legend on Preferred Securities, the Preferred
      Securities so issued shall bear the Restricted Securities Legend, or the
      Restricted Securities Legend shall not be removed, as the case may be,
      unless there is delivered to the Trust and the Property Trustee such
      satisfactory evidence, which may include an Opinion of Counsel, as may be
      reasonably required by the Initial Purchaser of Common Securities, that
      (i) neither the legend nor the restrictions on transfer set forth therein
      are required to ensure that transfers thereof comply with the provisions
      of Rule 144A under the Securities Act or any other available exemption
      from the registration requirements of the Securities Act or (ii) that such
      Securities may be sold pursuant to the provisions of Rule 144(k) under the
      Securities Act. Upon provision of such satisfactory evidence, the Property
      Trustee, at the written direction of an Administrative Trustee on behalf
      of the Trust, shall authenticate and deliver Preferred Securities that do
      not bear the Restricted Securities Legend.

            (b) [Reserved]

            (c) Restricted Securities Legend. Except as permitted by the last
      paragraph of this Section 9.2(c), each Preferred Security certificate
      evidencing the Global Preferred Securities and any Certificated Preferred
      Securities (and all Preferred Securities issued in exchange therefor or
      substitution thereof) shall bear a legend in substantially the following
      form (the "Restricted Securities Legend"):

      THIS SECURITY AND THE SHARES OF AMERICAN HOME MORTGAGE INVESTMENT CORP.
COMMON STOCK ISSUABLE UPON CONVERSION HAVE NOT BEEN REGISTERED UNDER THE
SECURITIES ACT OF 1933, AS AMENDED (THE "SECURITIES ACT"), OR ANY STATE
SECURITIES LAWS. NEITHER THIS SECURITY, THE SHARES OF AMERICAN HOME MORTGAGE
INVESTMENT CORP. COMMON STOCK ISSUABLE UPON CONVERSION OF THIS SECURITY NOR ANY
INTEREST OR PARTICIPATION HEREIN OR THEREIN MAY BE REOFFERED, SOLD, ASSIGNED,
TRANSFERRED, PLEDGED, ENCUMBERED OR OTHERWISE DISPOSED OF IN THE ABSENCE OF SUCH
REGISTRATION OR UNLESS SUCH TRANSACTION IS EXEMPT FROM, OR NOT SUBJECT TO,
REGISTRATION.

                                       47


      THE HOLDER OF THIS SECURITY, BY ITS ACCEPTANCE HEREOF, AGREES TO OFFER,
SELL OR OTHERWISE TRANSFER SUCH SECURITY, PRIOR TO THE DATE (THE "RESALE
RESTRICTION TERMINATION DATE") WHICH IS TWO YEARS AFTER THE LATER OF THE
ORIGINAL ISSUE DATE HEREOF AND THE LAST DATE ON WHICH AMERICAN HOME MORTGAGE
INVESTMENT CORP. OR ANY AFFILIATE OF AMERICAN HOME MORTGAGE INVESTMENT CORP. WAS
THE OWNER OF THIS SECURITY (OR ANY PREDECESSOR OF SUCH SECURITY) ONLY (A) TO
AMERICAN HOME MORTGAGE INVESTMENT CORP. OR ANY SUBSIDIARY THEREOF, (B) FOR SO
LONG AS THE SECURITIES ARE ELIGIBLE FOR RESALE PURSUANT TO RULE 144A, TO A
PERSON IT REASONABLY BELIEVES IS A "QUALIFIED INSTITUTIONAL BUYER" AS DEFINED IN
RULE 144A UNDER THE SECURITIES ACT THAT PURCHASES FOR ITS OWN ACCOUNT OR FOR THE
ACCOUNT OF A QUALIFIED INSTITUTIONAL BUYER TO WHICH NOTICE IS GIVEN THAT THE
TRANSFER IS BEING MADE IN RELIANCE ON RULE 144A, (C) PURSUANT TO A REGISTRATION
STATEMENT WHICH HAS BEEN DECLARED EFFECTIVE UNDER THE SECURITIES ACT, OR (D)
PURSUANT TO ANOTHER AVAILABLE EXEMPTION FROM THE REGISTRATION REQUIREMENTS OF
THE SECURITIES ACT, SUBJECT TO AMERICAN HOME MORTGAGE INVESTMENT CORP.'S, AND
THE PROPERTY TRUSTEE'S RIGHT PRIOR TO ANY SUCH OFFER, SALE OR TRANSFER PURSUANT
TO CLAUSE (D) TO REQUIRE THE DELIVERY OF AN OPINION OF COUNSEL, CERTIFICATION
AND/OR OTHER INFORMATION SATISFACTORY TO EACH OF THEM, AND IN EACH OF THE
FOREGOING CASES, A CERTIFICATE OF TRANSFER IN THE FORM APPEARING ON THE OTHER
SIDE OF THIS SECURITY IS COMPLETED AND DELIVERED BY THE TRANSFEROR TO THE
PROPERTY TRUSTEE. THIS LEGEND WILL BE REMOVED UPON THE REQUEST OF THE HOLDER
UPON THE EARLIER OF THE TRANSFER OF THE SECURITIES EVIDENCED HEREBY PURSUANT TO
CLAUSE (C) ABOVE AND THE RESALE RESTRICTION TERMINATION DATE. THE HOLDER OF THIS
SECURITY, BY ITS ACCEPTANCE HEREOF, AGREES THAT IT WILL DELIVER TO EACH PERSON
TO WHOM THE SECURITY EVIDENCED HEREBY IS TRANSFERRED (OTHER THAN A TRANSFER
PURSUANT TO CLAUSE (C) ABOVE) A NOTICE SUBSTANTIALLY TO THE EFFECT OF THIS
LEGEND.

            Upon any sale or transfer of a Restricted Preferred Security
      (including any Restricted Preferred Security represented by a Global
      Preferred Security) pursuant to an available exemption from the
      registration requirements of the Securities Act and compliance with the
      last two sentences of Section 9.2(a) all requirements pertaining to
      Restricted Securities Legends on any Preferred Security included within
      such sale or transfer will cease to apply, and beneficial interests in a
      Preferred Security in global form without Restricted Securities Legends
      will be available to transferees of such Preferred Securities. After such
      sale or transfer the Administrative Trustees shall execute and deliver and
      the Property Trustee shall, upon receipt of a written order of the Trust,
      authenticate a Preferred Security in global form without the Restricted
      Securities Legend (the "Unrestricted Global Preferred Security") to
      deposit with the Clearing Agency to evidence transfers of beneficial
      interests from the Global Preferred Security and the Registrar shall
      permit the Holder thereof to exchange such Restricted Preferred Security
      for an interest in the Unrestricted Global Preferred Security.

                                       48


            (d) Transfer and Exchange of Certificated Preferred Securities. When
      Certificated Preferred Securities are presented to the Registrar or
      co-Registrar

                  (x) to register the transfer of such Certificated Preferred
            Securities; or

                  (y) to exchange such Certificated Preferred Securities which
            became mutilated, destroyed, defaced, stolen or lost, for an equal
            number of Certificated Preferred Securities,

the Registrar or co-Registrar shall register the transfer or make the exchange
as requested if its reasonable requirements for such transaction are met;
provided, however, that the Certificated Preferred Securities surrendered for
transfer or exchange

                  (i) shall be duly endorsed or accompanied by a written
            instrument of transfer in form reasonably satisfactory to the Trust
            and the Registrar or co-Registrar, duly executed by the Holder
            thereof or his attorney duly authorized in writing; and

                  (ii) in the case of Certificated Preferred Securities that are
            Restricted Preferred Securities, and are being transferred or
            exchanged, such transfer or exchange shall be pursuant to, and in
            compliance with, clause (A), (B) or (C) below:

                        (A) if such Restricted Preferred Securities are being
                  delivered to the Registrar by a Holder for registration in the
                  name of such Holder, without transfer, such Holder shall
                  deliver a certification to that effect (in the form set forth
                  on the reverse of the Preferred Security);

                        (B) such Restricted Preferred Securities are being
                  transferred to the Initial Purchaser of Common Securities or a
                  subsidiary thereof; or

                        (C) if such Restricted Preferred Securities are being
                  transferred pursuant to an exemption from registration in
                  accordance with Rule 144A under the Securities Act or an
                  available exemption from the registration requirements of the
                  Securities Act, such Holder shall deliver: (i) a certification
                  to that effect (in the form set forth on the reverse of the
                  Preferred Security) and (ii) if the Trust or Registrar so
                  requests, evidence reasonably satisfactory to them as to the
                  compliance with the restrictions set forth in the Restricted
                  Securities Legend.

            (e) [Reserved]

            (f) Transfer and Exchange of Global Preferred Securities. The
      transfer and exchange of Global Preferred Securities or beneficial
      interests therein shall be effected through the Clearing Agency, in
      accordance with this Declaration (including applicable restrictions on
      transfer set forth herein, if any) and the procedures of the Clearing
      Agency therefor.

                                       49


            Notwithstanding any other provisions of this Declaration (other than
      subsection (g) of this Section 9.2), a Global Preferred Security may not
      be transferred as a whole except by the Clearing Agency to a nominee of
      the Clearing Agency or another nominee of the Clearing Agency or by the
      Clearing Agency or any such nominee to a successor Clearing Agency or a
      nominee of such successor Clearing Agency.

            (g) Restrictions on Transfer of a Beneficial Interest in a Global
      Preferred Security for a Certificated Preferred Security. Except as
      provided below, holders of beneficial interests in a Global Preferred
      Security shall not be entitled to have certificates registered in their
      names and will not receive physical delivery of certificates in definitive
      form.

                  (i) A Global Preferred Security deposited with the Clearing
            Agency or with the Property Trustee as custodian for the Clearing
            Agency pursuant to Section 7.3 shall be transferred to the
            beneficial owners thereof in the form of Certificated Preferred
            Securities only if (a) the Clearing Agency notifies the Initial
            Purchaser of Common Securities that it is unwilling or unable to
            continue as Clearing Agency for such Global Preferred Security or if
            at any time such Clearing Agency ceases to be a "clearing agency"
            registered under the Exchange Act and a clearing agency is not
            appointed by the Initial Purchaser of Common Securities within
            ninety (90) days of such notice, (b) a Default or an Event of
            Default has occurred and is continuing or (c) the Trust at its sole
            discretion elects to cause the issuance of Certificated Preferred
            Securities.

                  (ii) Any Global Preferred Security that is transferable to the
            beneficial owners thereof in the form of Certificated Preferred
            Securities pursuant to this Section 9.2 shall be surrendered by the
            Clearing Agency to the Property Trustee, to be so transferred, in
            whole or from time to time in part, without charge, and the Property
            Trustee shall authenticate and make available for delivery, upon
            such transfer of each portion of such Global Preferred Security, an
            equal aggregate liquidation amount of Preferred Securities of
            authorized denominations in the form of Certificated Preferred
            Securities. Any portion of a Global Preferred Security transferred
            pursuant to this Section shall be registered in such names and in
            such authorized denominations as the Clearing Agency, pursuant to
            instructions from its Clearing Agency Participants or otherwise,
            shall instruct the Property Trustee in writing. The Property Trustee
            shall deliver such Preferred Securities to the Persons in whose
            names such Preferred Securities are so registered in accordance with
            such instructions of the Clearing Agency. Any Preferred Security in
            the form of Certificated Preferred Securities delivered in exchange
            for an interest in the Restricted Global Preferred Security shall,
            except as otherwise provided in this Section 9.2, bear the
            Restricted Securities Legend.

                  (iii) In the event of the occurrence of any event specified in
            Section 9.2(g)(i), the Trust will promptly make available to the
            Property Trustee a reasonable supply of Certificated Preferred
            Securities in fully registered form without distribution coupons.

                                       50


            (h) Cancellation or Adjustment of Global Preferred Security. At such
      time as all beneficial interests in a Global Preferred Security have
      either been exchanged for Certificated Preferred Securities to the extent
      permitted by this Declaration or redeemed, repurchased or canceled in
      accordance with the terms of this Declaration, such Global Preferred
      Security shall be returned to the Clearing Agency for cancellation or
      retained and canceled by the Property Trustee. At any time prior to such
      cancellation, if any beneficial interest in a Global Preferred Security is
      exchanged for Certificated Preferred Securities, Preferred Securities
      represented by such Global Preferred Security shall be reduced and an
      adjustment shall be made on the books and records of the Clearing Agency
      and the Registrar, to reflect such reduction.

            (i) Legend on Global Securities. Any Preferred Security in global
      form may be endorsed with or have incorporated in the text thereof such
      legends or recitals or changes not inconsistent with the provisions of
      this Declaration as may be required by the Clearing Agency or by the
      National Association of Securities Dealers, Inc. in order for the
      Preferred Securities to be tradable on The PORTAL Market or as may be
      required for the Preferred Securities to be tradable on any other market
      developed for trading of securities pursuant to Rule 144A or required to
      comply with any applicable law or any regulation thereunder or with the
      rules and regulations of any securities exchange or automated quotation
      system upon which the Preferred Securities may be listed or traded or to
      conform with any usage with respect thereto, or to indicate any special
      limitations or restrictions to which any particular Securities are
      subject.

            (j) Obligations with Respect to Transfers of Preferred Securities.
      (i) To permit registrations of transfer, the Trust shall execute and the
      Property Trustee shall authenticate Global Preferred Securities at the
      Registrar's or co-Registrar's request in accordance with the terms of this
      Declaration.

                  (ii) Registrations of transfer will be effected without
            charge, but only upon payment (with such indemnity as the Trust or
            the Initial Purchaser of Common Securities may require) in respect
            of any tax or other governmental charge that may be imposed in
            relation to it.

                  (iii) The Registrar or co-Registrar shall not be required to:
            (a) issue, register the transfer of or exchange Preferred Securities
            during a period beginning at the opening of business fifteen (15)
            days before the day of mailing of a notice of redemption or any
            notice of selection of Preferred Securities for redemption and
            ending at the close of business on the day of such mailing; or (b)
            register the transfer or exchange of any Preferred Security selected
            for redemption, in whole or in part except, in the case of any
            Preferred Security being redeemed in part, any portion thereof not
            to be redeemed.

                  (iv) Prior to the due presentation for registration of
            transfer of any Preferred Security, the Trust, the Property Trustee,
            the Paying Agent, the Registrar or any co-Registrar may deem and
            treat the Person in whose name a Preferred Security is registered as
            the absolute owner of such Preferred Security for the purpose of
            receiving Distributions on such Preferred Security and for all other

                                       51


            purposes whatsoever, and none of the Trust, the Property Trustee,
            the Paying Agent, the Registrar or any co- Registrar shall be
            affected by notice to the contrary.

                  (v) All Preferred Securities issued upon any transfer or
            exchange pursuant to the terms of this Declaration shall evidence
            the same security and shall be entitled to the same benefits under
            this Declaration as the Preferred Securities surrendered upon such
            transfer or exchange.

            (k) No Obligation of the Property Trustee. (i) The Property Trustee
      shall have no responsibility or obligation to any beneficial owner of a
      Global Preferred Security, a Clearing Agency Participant in the Clearing
      Agency or other Person with respect to the accuracy of the records of the
      Clearing Agency or its nominee or of any Clearing Agency Participant
      thereof, with respect to any ownership interest in the Preferred
      Securities or with respect to the delivery to any Clearing Agency
      Participant, beneficial owner or other Person (other than the Clearing
      Agency) of any notice (including any notice of redemption) or the payment
      of any amount, under or with respect to such Preferred Securities. All
      notices and communications to be given to the Holders and all payments to
      be made to Holders under the Preferred Securities shall be given or made
      only to or upon the order of the registered Holders (which shall be the
      Clearing Agency or its nominee in the case of a Global Preferred
      Security). The rights of beneficial owners in any Global Preferred
      Security shall be exercised only through the Clearing Agency subject to
      the applicable rules and procedures of the Clearing Agency. The Property
      Trustee may conclusively rely and shall be fully protected in relying upon
      information furnished by the Clearing Agency or any agent thereof with
      respect to its Clearing Agency Participants and any beneficial owners.

                  (ii) The Property Trustee and the Registrar shall have no
            obligation or duty to monitor, determine or inquire as to compliance
            with any restrictions on transfer imposed under this Declaration or
            under applicable law with respect to any transfer of any interest in
            any Preferred Security (including any transfers between or among
            Clearing Agency Participants or beneficial owners in any Global
            Preferred Security) other than to require delivery of such
            certificates and other documentation or evidence as are expressly
            required by, and to do so if and when expressly required by, the
            terms of this Declaration, and to examine the same to determine
            substantial compliance as to form with the express requirements
            hereof.

SECTION 9.3  Deemed Security Holders.

      The Trustees may treat the Person in whose name any Security shall be
registered on the books and records of the Trust as the sole owner of such
Security 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 Security on the part of any Person, whether
or not the Trust shall have actual or other notice thereof.

                                       52


SECTION 9.4  Book-Entry Interests.

      Global Preferred Securities shall initially be registered on the books and
records of the Trust in the name of Cede & Co., the nominee of the Clearing
Agency and shall be in the form of a global certificate (the "Global
Certificate"), and no beneficial owner in any Global Preferred Security will
receive a Certificated Preferred Security representing such beneficial owner's
interests in such Global Preferred Securities, except as provided in Section
9.2. Unless and until definitive, fully registered Certificated Preferred
Securities have been issued to the beneficial owners in any Global Preferred
Security pursuant to Section 9.2:

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

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

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

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

SECTION 9.5 Notices to Clearing Agency.

      Whenever a notice or other communication to the Preferred Security Holders
is required to be given by a Trustee under this Declaration, such Trustee shall
give all such notices and communications specified herein to be given to the
Holders of Global Preferred Securities to the Clearing Agency, and shall have no
notice obligations to the beneficial owners in any Global Preferred Security.

SECTION 9.6  Appointment of Successor Clearing Agency.

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

                                       53


                                    ARTICLE X
     LIMITATION OF LIABILITY OF HOLDERS OF SECURITIES, TRUSTEES OR OTHERS

SECTION 10.1  Liability.

            (a) Except as expressly set forth in this Declaration, the
      Securities Guarantee and the terms of the Securities, the Initial
      Purchaser of Common Securities shall not be:

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

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

            (b) The Debenture Issuer, in its capacity as such, shall be liable
      for all of the debts and obligations of the Trust (other than in respect
      of the Securities) as provided in the Indenture.

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

SECTION 10.2  Exculpation.

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

                                       54


SECTION 10.3  Fiduciary Duty.

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

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

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

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

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

SECTION 10.4  Indemnification.

            (a) (i) The Debenture Issuer shall indemnify, to the full extent
      permitted by law, any Company Indemnified Person who was or is a party or
      is threatened to be made

                                       55


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

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

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

                  (iv) Any indemnification under paragraphs (i) and (ii) of this
            Section 10.4(a) (unless ordered by a court) shall be made by the
            Debenture Issuer only as authorized in the specific case upon a
            determination that indemnification of the Company Indemnified Person
            is proper in the circumstances because he has met the applicable
            standard of conduct set forth in paragraphs (i) and (ii). Such
            determination shall be made by the Common Security Holder of the
            Trust.

                                       56


                  (v) Expenses (including attorneys' fees and expenses) incurred
            by a Company Indemnified Person in defending a civil, criminal,
            administrative or investigative action, suit or proceeding referred
            to in paragraphs (i) and (ii) of this Section 10.4(a) shall be paid
            by the Debenture Issuer in advance of the final disposition of such
            action, suit or proceeding upon receipt of an undertaking by or on
            behalf of such Company Indemnified Person to repay such amount if it
            shall ultimately be determined that he is not entitled to be
            indemnified by the Debenture Issuer as authorized in this Section
            10.4(a). Notwithstanding the foregoing, no advance shall be made by
            the Debenture Issuer if a determination is reasonably and promptly
            made by the Common Security Holder of the Trust, that, based upon
            the facts known to the Common Security Holder at the time such
            determination is made, such Company Indemnified Person acted in bad
            faith or in a manner that such person did not believe to be in or
            not opposed to the best interests of the Trust, or, with respect to
            any criminal proceeding, that such Company Indemnified Person
            believed or had reasonable cause to believe his conduct was
            unlawful. In no event shall any advance be made in instances where
            the Common Security Holder reasonably determine that such person
            deliberately breached his duty to the Trust or its Common or
            Preferred Security Holders.

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

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

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

                                       57


            resulting or surviving entity as he would have with respect to such
            constituent entity if its separate existence had continued.

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

            (b) The Debenture Issuer agrees to indemnify (i) the Property
      Trustee, (ii) the Delaware Trustee, (iii) any Affiliate of the Property
      Trustee or the Delaware Trustee, and (iv) any officers, directors,
      stockholders, members, partners, employees, representatives, custodians,
      nominees or agents of the Property Trustee or the Delaware Trustee (each
      of the Persons in (i) through (iv), including the Property Trustee and the
      Delaware Trustee in their respective individual capacities, being referred
      to as a "Fiduciary Indemnified Person") for, and to hold each Fiduciary
      Indemnified Person harmless against, any and all loss, liability, damage,
      claim or expense including taxes (other than taxes based on the income of
      such Fiduciary Indemnified Person) incurred without negligence or bad
      faith on the part of such Fiduciary Indemnified Person, arising out of or
      in connection with the acceptance or administration of the trust or trusts
      hereunder, including the advancement of funds to cover the costs and
      expenses (including reasonable legal fees and expenses) of defending
      against or investigating any claim or liability in connection with the
      exercise or performance of any of the powers or duties of such Fiduciary
      Indemnified Person hereunder. The obligation to indemnify and advance as
      set forth in this Section 10.4(b) shall survive the resignation or removal
      of the Property Trustee or the Delaware Trustee and the satisfaction and
      discharge of this Declaration.

SECTION 10.5  Outside Businesses.

      Any Covered Person, the Initial Purchaser of Common Securities, 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 business of the Trust, and the Trust and
the Holders shall have no rights by virtue of this Declaration in and to such
independent ventures or the income or profits derived therefrom, and the pursuit
of any such venture, even if competitive with the business of the Trust, shall
not be deemed wrongful or improper. No Covered Person, the Initial Purchaser of
Common Securities, 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 Initial Purchaser of
Common Securities, 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 Initial Purchaser of
Common Securities or any Affiliate of the Initial Purchaser of Common
Securities, 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 Initial
Purchaser of Common Securities or its Affiliates.

                                       58


SECTION 10.6  Compensation; Fees.

      The Debenture Issuer agrees:

            (a) to pay to the Trustees from time to time such compensation for
      all services rendered by them hereunder as the parties shall agree in
      writing from time to time (which compensation shall not be limited by any
      provision of law in regard to the compensation of a trustee of an express
      trust); and

            (b) except as otherwise expressly provided herein, to reimburse the
      Trustees upon request for all reasonable expenses, disbursements and
      advances incurred or made by the Trustees in accordance with any provision
      of this Declaration (including the reasonable compensation and the
      expenses and disbursements of their respective agents and counsel), except
      any such expense, disbursement or advance as may be attributable to its
      negligence or bad faith.

The provisions of this Section 10.6 shall survive the dissolution of the Trust
and the termination of this Declaration and the removal or resignation of any
Trustee.

      No Trustee may claim any lien or charge on any property of the Trust as a
result of any amount due pursuant to this Section 10.6.

                                   ARTICLE XI
                                   ACCOUNTING

SECTION 11.1  Fiscal Year.

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

SECTION 11.2  Certain Accounting Matters.

            (a) At all times during the existence of the Trust, the
      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 U.S. generally accepted accounting principles, consistently applied.

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

            (c) 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 an

                                       59


      IRS 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 11.3  Banking.

      The Trust may 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 Trustee Account and no other funds of the Trust shall be deposited
in the Property Trustee 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 Trustee Account.

SECTION 11.4  Withholding.

      The Trust and the Paying Agent shall comply with all withholding and
backup withholding tax requirements under United States federal, state and local
law. The Paying Agent on behalf of the Trust shall request, and the Holders
shall provide to the Trust and the Initial Purchaser of Common Securities, such
forms or certificates as are necessary to establish an exemption from
withholding and backup withholding tax with respect to each Holder, including an
IRS Form W-9 or IRS Form W-8 (with all appropriate attachments), or any
successor form, and any representations and forms as shall reasonably be
requested by the Paying Agent on behalf of the Trust to assist it in determining
the extent of, and in fulfilling, its withholding and backup withholding tax
obligations. The Paying Agent shall file required forms with applicable
jurisdictions and, unless an exemption from withholding and backup withholding
tax is properly established by a Holder, shall remit amounts withheld with
respect to the Holder to applicable jurisdictions. To the extent that the Trust
is required to withhold and pay over any amounts to any jurisdiction with
respect to Distributions or allocations to any Holder, the amount withheld shall
be deemed to be a Distribution in the amount of the withholding to the Holder.
In the event of any claimed overwithholding, Holders shall be limited to an
action against the applicable jurisdiction. If the amount required to be
withheld was not withheld from actual Distributions made, the Paying Agent on
behalf of the Trust may reduce subsequent Distributions by the amount of such
required withholding.

      action shall not adversely affect in any material respect the interests of
      any Holders of the Securities and any such amendments of the Declaration
      shall become effective when notice thereof is given to the Holders of the
      Securities.

            (b) Except as provided in (c) below, and the terms of the
      Securities, this Declaration may be amended by the Trustees and the
      Initial Purchaser of Common Securities with the consent of Holders
      representing not less than a Majority in liquidation amount of the

      approval of not less than a Majority in liquidation amount of such class
      of securities affected thereby.

      of Counsel experienced in such matters to the effect that such amendment
      or the exercise of any power granted to the Trustees in accordance with
      such amendment will not affect the Trust's status as a grantor trust, the
      Debentures' status as indebtedness of the Debenture Issuer for United
      States federal income tax purposes or the Trust's exemption from status as
      an "investment company" under the Investment Company Act.

SECTION 12.2 Meetings of the Holders; 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

      shall be given by delivering to the Administrative Trustees one or more
      notices in writing stating that the signing Holders wish to call a meeting
      and indicating the general or specific purpose for which the meeting is to
      be called. Any Holders calling a meeting shall specify in writing the
      Security Certificates held by the Holders 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:

                  (i) the Property Trustee will cause a notice to be given of
            any such meeting to all the Holders having a right to vote thereat
            at least ten (10) days and not more than sixty (60) days before the
            date of such meeting. Whenever a vote, consent or approval of the
            Holders is permitted or required under this Declaration or the rules
            of any stock exchange on which the Preferred Securities are listed
            or admitted for trading, such vote, consent or approval may be given
            at a meeting of the Holders. Any action that may be taken at a
            meeting of the Holders may be taken without a meeting if a consent
            in writing setting forth the action so taken is signed by the
            Holders owning not less than the minimum amount of Securities in
            liquidation an amount that would be necessary to authorize or take
            such action at a meeting at which all Holders 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 entitled to
            vote who have not consented in writing. The Trustees may specify
            that any written ballot submitted to the Security Holder for the
            purpose of taking any action without a meeting shall be returned to
            the Trust within the time specified by the Trustees;

                  (ii) each Holder may authorize any Person to act for it by
            proxy on all matters in which a Holder 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
            executing it. Except as otherwise provided herein, all matters
            relating to the giving, voting or validity of proxies shall be
            governed by the General Corporation Law of the State of Delaware
            relating to proxies, and judicial interpretations thereunder, as if
            the Trust were a Delaware corporation and the Holders were
            stockholders of a Delaware corporation. The Holder of a Global
            Preferred Security may grant proxies and otherwise authorize any
            Person, including Participants and Persons that may hold interests
            through Participants, to take any action which such Holder is
            entitled to take under this Declaration or the Securities;

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

                                       62


                  (iv) unless the Statutory Trust Act, this Declaration, the
            terms of the Securities or the Trust Indenture Act, otherwise
            provides, the Administrative Trustees, in their sole discretion,
            shall establish all other provisions relating to meetings of
            Holders, including notice of the time, place or purpose of any
            meeting at which any matter is to be voted on by any Holders, 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.

      properly completed and executed IRS Form W-9, W-8BEN, W-8ECI, or W-8IMY or
      any successor thereto (with all appropriate attachments), that eliminates
      United States federal withholding tax and backup withholding tax on
      payments under the Declaration promptly upon the request of

                                       64


      an Administrative Trustee and prior to any such form previously provided
      by such Holder becoming obsolete or incorrect.

            (b) If such Holder of Preferred Securities is not a United States
      Person for United States federal income tax purposes (a "U.S. Person"),
      then such Holder will irrevocably appoint a U.S. Person with discretionary
      powers to act as its agent with respect to consents and other votes under
      the Preferred Securities of such Holder, at such time that any such
      consent or other vote arises under the Declaration. Note: Purchasers that
      are not U.S. Persons are required to irrevocably appoint a U.S. Person
      with discretionary authority as their agent with respect to any matter
      that requires consent or a vote at such time that any such consent or
      other vote arises under the Declaration. Any successor agent of a foreign
      purchaser must also be a U.S. Person

            (c) Such Holder represents and warrants that it will, unless
      otherwise required by law, (i) treat the Trust as a grantor trust for
      United States federal income tax purposes, (ii) treat the Securities as
      undivided beneficial ownership interests in the Trust Property for United
      States federal income tax purposes, and (iii) treat the Debentures as
      indebtedness of the Debenture Issuer for United States federal income tax
      purposes.

            (d) Such Holder acknowledges that the Trust, the Debenture Issuer,
      the Guarantor and others will rely upon the truth and accuracy of the
      foregoing acknowledgments, representations, warranties and agreements and
      agree that if any of the acknowledgments, representations, warranties and
      agreements deemed to have been made by the purchase of the Preferred
      Securities are no longer accurate, such Holder shall promptly notify the
      Debenture Issuer.

            Until the Restriction Termination Date, the Trust Securities shall
be subject to the following limitations on ownership, unless the Corporation at
the direction of its Board of Directors waives the limitation. Any violation of
this section shall be treated as a violation of the Ownership Limit for Equity

and this Declaration, respectively, and as provided below, the affected Equity
Stock and/or Trust Securities shall be transferred automatically to a Share
Trust and designated as Shares-in-Trust:

856(h)(3)(A) of the Code and determined without regard to whether such ownership
has the effect of meeting the stock ownership requirement of Section 542(a)(2)

Owned" shall have the correlative meanings.

            "Common Stock", for purposes of this Article XVI, shall mean the

Securities, 9.8% of the total value of the outstanding Trust Securities.

to the Restriction Termination Date: (w) no Individual shall have Beneficial
Ownership of Common Stock, Equity Stock or Trust Securities (or any combination

            (ii) Any Transfer that would result in a violation of the
restrictions in Section (b)(i) above, shall be void ab initio as to the
purported Transfer of such number of shares of Common Stock or Equity Stock or

such shares of Equity Stock or amount of Trust Securities.

      (c) Automatic Transfer to Share Trust.

            (i) If, at any time prior to the Restriction Termination Date, there
is a purported Transfer or Non-Transfer Event such that, if effective, would
result in any Individual having Beneficial Ownership of Common Stock, Equity
Stock or Trust Securities (or any combination of the foregoing) in excess of the
Ownership Limit, any Excepted Holder having Beneficial Ownership of Common
Stock, Equity Stock or Trust Securities (or any combination of the foregoing) in
excess of the Excepted Holder Limit as applicable to such Excepted Holder) then,
except as otherwise provided in or by operation of Section 16.1(f) as to such
Individual or Excepted Holder (x) the Purported Record Transferee (and the
Purported Beneficial Transferee, if different) shall acquire no right or
interest (or, in the case of a Non-Transfer Event, the person holding record
title to the shares of Common Stock or Equity Stock or amount of Trust
Securities (or any combination of the foregoing) Beneficially Owned by such
Beneficial Owner shall cease to own any right or interest) in such number of
shares of Common Stock or Equity Stock or amount of Trust Securities (or any
combination of the foregoing) that would cause such Purported Record Transferee
(and the Purported Beneficial Transferee, if different) to Beneficially Own
shares of Common Stock, Equity Stock or Trust Securities in excess of the
Ownership Limit or Excepted Holder Limit, as the case may be (rounded up to the
nearest whole share, if applicable), (y) such number of shares of Common Stock
or Equity Stock or amount of Trust Securities (or any combination of the
foregoing) in excess of the Ownership Limit or Excepted Holder Limit, as the
case may be (rounded up to the nearest whole share or penny, as applicable),
shall be designated Shares-in-Trust and, in accordance with the provisions of
Section 16.2(a), transferred automatically and by operation of this Declaration
to the Share Trust to be held in accordance with Section 16.2, and (z) such
Purported Record Transferee (and the Purported Beneficial Transferee, if
different) shall submit such number of shares of Common Stock or Equity Stock or
amount of Trust Securities (or any combination of the foregoing) to the Share
Trust for registration in the name of the Share Trustee. Any Purported Record
Transferee (and the Purported Beneficial Transferee, if different) shall acquire
no right or interest (or, in the case of a Non-Transfer Event, the person
holding title to the shares Beneficially Owned by such Beneficial Owner shall
cease to own any right or interest) in such number of shares or amount of Trust
Securities that would cause such person to own shares or an amount of Trust
Securities in

                                       72


excess of the Ownership Limit or Excepted Holder Limit, as the case may be. Such
transfer to a Share Trust and the designation of shares or amount of Trust
Securities as Shares-in-Trust shall be effective as of the close of business on
the business day prior to the date of the Transfer or Non-Transfer Event, as the
case may be.

            (ii) If, at any time prior to the Restriction Termination Date,
there is a purported Transfer or Non-Transfer Event that, if effective, would
(i) result in the Corporation being "closely held" within the meaning of Section
856(h) of the Code or (ii) cause the Corporation to otherwise fail to qualify as
a REIT, as the case may be, then (x) the Purported Record Transferee (and the
Purported Beneficial Transferee, if different) shall acquire no right or
interest (or, in the case of a Non-Transfer Event, the person holding record
title to the shares of Equity Stock or Trust Securities with respect to which
such Non-Transfer Event occurred, shall cease to own any right or interest) in
such number of shares of Equity Stock or amount of Trust Securities (or any
combination of the foregoing), the ownership of which by such Purported Record
Transfer (and the Purported Beneficial Transferee, if different) would (A)
result in the Corporation being "closely held" within the meaning of Section
856(h) of the Code or (B) otherwise cause the Corporation to fail to qualify as
a REIT, as the case may be, then (y) such number of shares of Equity Stock
(rounded up to the nearest whole share) or amount of Trust Securities (rounded
up to the nearest penny) (or any combination of the foregoing) shall be
designated Shares-in-Trust and, in accordance with the provisions of Section
16.2(a), transferred automatically and by operation of this Declaration to the
Share Trust to be held in accordance with Section 16.2, and (z) the Purported
Record Transferee (and the Purported Beneficial Transferee, if different) shall
submit such number of shares of Equity Stock or amount of Trust Securities (or
any combination of the foregoing), as the case may be, to the Share Trust for
registration in the name of the Share Trustee.

            (iii) To the extent that, upon a purported Transfer or Non-Transfer
Event, a violation of any restriction set forth in Section 16.1(b)(i) above
would nonetheless be continuing (for example, where the ownership of Equity
Stock or Trust Securities by a single Share Trust would violate the restriction
that the Corporation must not be "closely held"), then shares of Equity Stock or
amounts of Trust Securities shall be transferred to that number of Share Trusts,
each having a distinct Share Trustee and a Charitable Beneficiary or Charitable
Beneficiaries that are distinct from those of each other Share Trust, such that
there is no violation of any restriction set forth in Section 16.1(b)(i).

      (d) Remedies for Breach. If the Board of Directors or the Corporation or
its designee shall at any time determine in good faith that a person intends to
acquire or has attempted to acquire Beneficial Ownership of Common Stock, Equity
Stock or Trust Securities (or any combination thereof) in violation of Section
16.1(b), or that a purported Transfer of Common Stock or Equity Stock or Trust
Securities (or any combination thereof) has otherwise taken place in violation
of Section 16.1(b), the Board of Directors or the Corporation or its designee
shall take such action as it deems advisable to refuse to give effect to or to
prevent such Transfer or acquisition, including, but not limited to, refusing to
give effect to such Transfer or acquisition on the books of the Corporation or
instituting proceedings to enjoin such Transfer or acquisition; provided,
however, that any Transfer, attempted Transfer, acquisition or attempted
acquisition in violation of Section 16.1(b)(i) shall automatically result in the
Transfer described in Section

                                       73


16.1(c), irrespective of any action (or non-action) by the Board of Directors,
except as provided in Section 16.1(f).

      (e) Notice of Restricted Transfer.

            (i) Any Person who acquires or attempts to acquire Common Stock,
Equity Stock or Trust Securities in violation of Section 16.1(b), and any Person
who is a Purported Record Transferee or a Purported Beneficial Transferee of
shares of Common Stock, Equity Stock or Trust Securities that are transferred to
a Share Trust under Section 16.1(c), shall immediately give written notice to
the Corporation of such event, shall submit to the Corporation such number of
shares of Common Stock or Equity Stock or amount of Trust Securities to be
transferred to the Share Trust and shall provide to the Corporation such other
information as the Corporation may request in order to determine the effect, if
any, of such Transfer or attempted Transfer or such Non-Transfer Event on the
Corporation's status as a REIT.

            (ii) Prior to the Restriction Termination Date, each Person who is a
Beneficial Owner of Trust Securities of the Corporation (treating the Trust
Securities as Equity Stock for this purpose) and each Person (including a Trust
Securities holder of record) who is holding Trust Securities of the Corporation
for a Beneficial Owner shall provide to the Corporation such information as the
Corporation may reasonably request in order to determine the Corporation's
status as a REIT, to comply with the requirements of any taxing authority or
governmental agency or to determine any such compliance and to ensure compliance
with the Ownership Limit or Excepted Holder Limit as applicable to such
Beneficial Owner.

      (f) Exceptions.

            (i) The Board of Directors may, but in no case shall the Board of
Directors be required to, waive, in whole or in part, application of the
Ownership Limit or Excepted Holder Limit to a Person otherwise subject to such
limit and/or establish, in lieu of the Ownership Limit or Excepted Holder Limit,
or any portion or aspect thereof, then applicable to such Person, an Excepted
Holder Limit (or a new Excepted Holder Limit) as applicable to the ownership,
beneficial or otherwise, of Common Stock and/or Equity Stock and/or Trust
Securities by such Person, if it concludes that the ownership of Common Stock
and/or Equity Stock and/or Trust Securities by such Person will not (A) result
in the Corporation being "closely held" within the meaning of Section 856(h) of
the Code or (B) otherwise cause the Corporation to fail to qualify as a REIT
under the Code; provided, however, that (i) the Board of Directors obtains from
such Person such representations and undertakings, if any, as the Board of
Directors may in its sole discretion require (including, without limitation, an
agreement as to a reduced Ownership Limit or Excepted Holder Limit for such
Person), and (ii) such Person agrees in writing that any violation or attempted
violation of any such or any other limitations as the Board of Directors may
establish for such Person, or such other restrictions as the Board may in its
sole discretion impose with respect to such Person at the time of granting such
waiver or exception, will result in transfer to the Share Trust of Common Stock,
Equity Stock or Trust Securities pursuant to Section 16.1(c). In making any
determination to waive application of the Ownership Limit or Excepted Holder
Limit or to establish an Excepted Holder Limit (or a new Excepted Holder Limit)
for any Person, the Board of Directors, in its sole and absolute discretion,
may, but shall not be required to, receive either a certified copy of a ruling
from the Internal Revenue Service or

                                       74


an opinion of counsel satisfactory to the Board of Directors that concludes that
the ownership of Equity Stock or Trust Securities by such Person will not (A)
result in the Corporation being "closely held" within the meaning of Section
856(h) of the Code or (B) otherwise cause the Corporation to fail to qualify as
a REIT under the Code. Unless and until the Board of Directors waives the
application of the Ownership Limit or Excepted Holder Limit as applicable to any
Person (or even thereafter insofar as such waiver did not or does not operate to
relieve some restrictive portion or aspect of the Ownership Limit or Excepted
Holder Limit as applicable to such Person), the Ownership Limit and/or Excepted
Holder Limit, as applicable, shall apply to such Person, notwithstanding the
fact that if such Person were otherwise to Acquire Equity Stock or Trust
Securities in excess of the Ownership Limit or Excepted Holder Limit, as
applicable, such Acquisition would not adversely affect the Corporation's
qualification as a REIT under the Code.

            (ii) If the Board of Directors makes a determination to waive the
Ownership Limit or Excepted Holder Limit, or to establish an Excepted Holder
Limit (or a new Excepted Holder Limit) as applicable to any Person, the Board
may revoke the waiver, or reduce the Excepted Holder Limit applicable to an
Excepted Holder, only (a) with the written consent of such Person at any time,
or (b) pursuant to the terms and conditions of the representations and
undertakings, if any, entered into with such Person in connection with the
granting of the waiver or the establishment of the Excepted Holder Limit for
such Person. No Excepted Holder Limit shall be reduced to a percentage that is
less than the Ownership Limit. Notwithstanding the foregoing, nothing in this
Section 16.1(f)(ii) is intended to limit or modify the restrictions on ownership
contained in Section 16.1(b) hereof and the authority of the Board of Directors
under this Section 16.1(f).

      (g) Legend. Each Preferred Security Certificate shall bear substantially
the following legend:

      THIS SECURITY AND THE SHARES OF COMMON STOCK ISSUABLE UPON CONVERSION OF
      THIS SECURITY ARE SUBJECT TO SIGNIFICANT RESTRICTIONS ON OWNERSHIP AND
      TRANSFER. EXCEPT AS OTHERWISE PROVIDED PURSUANT TO AHM CAPITAL TRUST I'S
      AMENDED AND RESTATED DECLARATION OF TRUST, DATED JUNE 28, 2007, AS THE
      SAME MAY BE AMENDED OR SUPPLEMENTED FROM TIME TO TIME, (I) NO INDIVIDUAL
      MAY BENEFICIALLY OWN TRUST SECURITIES IN EXCESS OF 9.8% OF THE TOTAL VALUE
      OF THE TRUST SECURITIES, (II) NO INDIVIDUAL MAY BENEFICIALLY OWN SHARES OF
      COMMON STOCK OF AMERICAN HOME MORTGAGE INVESTMENT CORP. OR TRUST
      SECURITIES OR ANY COMBINATION THEREOF IN EXCESS OF 6.5% OF THE MORE
      RESTRICTIVE OF THE TOTAL NUMBER OR VALUE OF THE OUTSTANDING SHARES OF
      COMMON STOCK OF AMERICAN HOME MORTGAGE INVESTMENT CORP. (TAKING INTO
      ACCOUNT THE COMMON STOCK INTO WHICH THE TRUST SECURITIES ARE CONVERTIBLE
      TO THE EXTENT PROVIDED IN CODE SECTION 544 AND THE TREASURY REGULATIONS
      PROMULGATED THEREUNDER), (III) NO INDIVIDUAL MAY BENEFICIALLY OWN SHARES
      OF EQUITY STOCK OF AMERICAN HOME MORTGAGE INVESTMENT CORP. OR TRUST
      SECURITIES OR ANY COMBINATION THEREOF IF IT WOULD CAUSE ANY INDIVIDUAL TO
      BENEFICIALLY OWN IN EXCESS OF 6.5% OF THE VALUE OF THE SHARES OF

                                       75


      EQUITY STOCK, TREATING THE TRUST SECURITIES AS EQUITY STOCK OR,
      ALTERNATIVELY, TREATING THE TRUST SECURITIES AS THE COMMON STOCK INTO
      WHICH THEY ARE CONVERTIBLE (TO THE EXTENT PROVIDED IN CODE SECTION 544 AND
      THE TREASURY REGULATIONS PROMULGATED THEREUNDER), IF EITHER TREATMENT
      WOULD CAUSE THIS PROVISION TO BE VIOLATED, (IV) NO PERSON MAY BENEFICIALLY
      OWN SHARES OF EQUITY STOCK OF AMERICAN HOME MORTGAGE INVESTMENT CORP. OR
      TRUST SECURITIES OR ANY COMBINATION THEREOF IF SUCH OWNERSHIP WOULD RESULT
      IN AMERICAN HOME MORTGAGE INVESTMENT CORP. BEING "CLOSELY HELD" UNDER
      SECTION 856(h) OF THE INTERNAL REVENUE CODE OF 1986, AS AMENDED (THE
      "CODE"), AND (V) NO PERSON MAY BENEFICIALLY OWN SHARES OF EQUITY STOCK OF
      AMERICAN HOME MORTGAGE INVESTMENT CORP. OR TRUST SECURITIES OR ANY
      COMBINATION THEREOF IF SUCH OWNERSHIP WOULD CAUSE AMERICAN HOME MORTGAGE
      INVESTMENT CORP. TO FAIL TO QUALIFY AS A REAL ESTATE INVESTMENT TRUST
      UNDER THE CODE. ANY PERSON WHO ATTEMPTS OR PROPOSES TO BENEFICIALLY OWN
      SHARES OF EQUITY STOCK OF AMERICAN HOME MORTGAGE INVESTMENT CORP. OR TRUST
      SECURITIES OR ANY COMBINATION THEREOF IN EXCESS OF THE ABOVE LIMITATIONS
      MUST IMMEDIATELY NOTIFY AMERICAN HOME MORTGAGE INVESTMENT CORP. IN
      WRITING. IF AN ATTEMPT IS MADE TO VIOLATE OR THERE IS A VIOLATION OF THESE
      RESTRICTIONS, (A) ANY PURPORTED TRANSFER WILL BE VOID AB INITIO AND WILL
      NOT BE RECOGNIZED BY AMERICAN HOME MORTGAGE INVESTMENT CORP. AND (B) ANY
      PURPORTED OR ATTEMPTED BENEFICIAL OWNERSHIP OF SHARES OF EQUITY STOCK OF
      AMERICAN HOME MORTGAGE INVESTMENT CORP. OR TRUST SECURITIES OR ANY
      COMBINATION THEREOF IN VIOLATION OF THESE RESTRICTIONS, WHETHER AS A
      RESULT OF A TRANSFER OR NON-TRANSFER EVENT, WILL BE TRANSFERRED
      AUTOMATICALLY TO A SHARE TRUST AND SHALL BE DESIGNATED SHARES-IN-TRUST.
      ALL TERMS USED IN THIS LEGEND AND DEFINED IN AHM CAPITAL TRUST I'S AMENDED
      AND RESTATED DECLARATION OF TRUST DATED JUNE 28, 2007, HAVE THE MEANINGS
      PROVIDED IN AHM CAPITAL TRUST I'S AMENDED AND RESTATED DECLARATION OF
      TRUST DATED JUNE 28, 2007, AS THE SAME MAY BE AMENDED OR SUPPLEMENTED FROM
      TIME TO TIME, A COPY OF WHICH, INCLUDING THE RESTRICTIONS ON OWNERSHIP AND
      TRANSFER, WILL BE SENT WITHOUT CHARGE TO EACH SECURITYHOLDER WHO SO
      REQUESTS. THIS LEGEND IS INTENDED TO PREVENT AMERICAN HOME MORTGAGE
      INVESTMENT CORP. FROM BEING TREATED AS CLOSELY HELD WITHIN THE MEANING OF
      SECTION 856(a)(6) AND SECTION 856(h) OF THE INTERNAL REVENUE CODE, AND
      SHALL BE CONSTRUED CONSISTENT WITH THIS INTENT.

      (h) Remedies Not Limited. Nothing contained in this Article XVI shall
limit the authority of the Board of Directors to take such other action as it
deems necessary or advisable to protect the Corporation and the interests of its
stockholders in preserving the Corporation's status as a REIT.

                                       76


      (i) Ambiguity. In the case of an ambiguity in the application of any of
the provisions, including any definition contained in Section 16.1(a) hereof,
the Board of Directors shall have the power to determine the application of the
provisions with respect to any situation based on the facts known to it.

      (j) Severability. If any provision or any application of any such
provision is determined to be invalid by a federal or state court having
jurisdiction over the issue, the validity of the remaining provisions shall not
be affected and other applications of such provision shall be affected only to
the extent necessary to comply with the determination of such court.

SECTION 16.2  Shares-in-Trust.

      (a) Share Trust. Any shares of Equity Stock or Trust Securities
transferred to a Share Trust and designated Shares-in-Trust pursuant to Section
16.1(c) shall be held for the exclusive benefit of the Charitable Beneficiary.
The Corporation shall name a Charitable Beneficiary and Share Trustee of each
Share Trust within five (5) days after discovery of the existence thereof. Any
transfer to a Share Trust, and subsequent designation of shares of Equity Stock
or Trust Securities as Shares-in-Trust, pursuant to Section 16.1(c) shall be
effective as of the close of business on the business day prior to the date of
the Transfer or Non-Transfer Event that results in the transfer to the Share
Trust. Shares-in-Trust shall remain issued and outstanding shares of Equity
Stock of the Corporation and issued and outstanding Trust Securities, as the
case may be, and shall be entitled to the same rights and privileges on
identical terms and conditions as are all other issued and outstanding shares of
Equity Stock or Trust Securities of the same class and series. When transferred
to the Permitted Transferee in accordance with the provisions of Section 16.2(c)
hereof, such Shares-in-Trust shall cease to be designated as Shares-in-Trust.

      (b) Dividend Rights. The Share Trustee, as record holder of
Shares-in-Trust, shall be entitled to receive all dividends and distributions,
as the case may be, as may be declared by the Board of Directors on such shares
of Equity Stock or shall be payable on the Trust Securities and shall hold such
dividends and distributions in trust for the benefit of the Charitable
Beneficiary. The Purported Record Transferee (or the Purported Beneficial
Transferee, if applicable) with respect to Shares-in-Trust shall repay to the
Share Trustee the amount of any dividends and distributions received by it that
(i) are attributable to any shares of Equity Stock or Trust Securities
designated as Shares-in-Trust and (ii) the record date of which was on or after
the date that such shares became Shares-in-Trust. The Corporation shall take all
measures that it determines reasonably necessary to recover the amount of any
such dividend and distribution paid to the Purported Record Transferee (or
Purported Beneficial Transferee, if applicable), including, if necessary,
withholding any portion of future dividends and distributions payable on shares
of Equity Stock or Trust Securities Beneficially Owned by the Person who, but
for the provisions of Section 16.1(c), would Beneficially Own the
Shares-in-Trust; and, as soon as reasonably practicable following the
Corporation's receipt or withholding thereof, shall pay over to the Share
Trustee for the benefit of the Charitable Beneficiary the dividends and
distributions so received or withheld, as the case may be.

      (c) Rights Upon Liquidation. In the event of any voluntary or involuntary
liquidation, dissolution or winding up of, or any distribution of the assets of
(other than a dividend), the Corporation, each Share Trustee of Shares-in-Trust
shall be entitled to receive,

                                       77


ratably with each other holder of shares of Equity Stock or Trust Securities, as
the case may be, of the same class or series, that portion of the assets of the
Corporation that is available for distribution to the holders of such class and
series of Equity Stock or Trust Securities. The Share Trustee shall distribute
to the Purported Record Transferee the amounts received upon such liquidation,
dissolution, or winding up, or distribution; provided, however, that the
Purported Record Transferee shall not be entitled to receive amounts pursuant to
this Section 16.2(c) in excess of, in the case of a purported Transfer in which
the Purported Record Transferee gave value for shares of Equity Stock or Trust
Securities and which Transfer resulted in the transfer of the shares or Trust
Securities to the Share Trust, the price per share or Trust Securities, if any,
such Purported Record Transferee paid for the shares of Equity Stock or Trust
Securities and, in the case of a Non-Transfer Event or Transfer in which the
Purported Record Transferee did not give value for such shares or Trust
Securities (e.g., if the shares were received through a gift or devise) and
which Non-Transfer Event or Transfer, as the case may be, resulted in the
transfer of shares or Trust Securities to the Share Trust, the price per share
or Trust Securities equal to the Market Price on the date of such Non-Transfer
Event or Transfer. Any remaining amount in such Share Trust shall be distributed
to the Charitable Beneficiary.

      (d) Voting Rights. The Share Trustee shall be entitled to vote all
Shares-in-Trust. Any vote by a Purported Record Transferee as a holder of shares
of Equity Stock or Trust Securities prior to the discovery by the Corporation
that the shares of Equity Stock or Trust Securities are Shares-in-Trust shall,
subject to applicable law, be rescinded and shall be void ab initio with respect
to such Shares-in-Trust and the Purported Record Transferee shall be deemed to
have given, as of the close of business on the business day prior to the date of
the purported Transfer or Non-Transfer Event that results in the transfer to the
Share Trust of shares of Equity Stock or Trust Securities under Section 16.1(c)
hereof, an irrevocable proxy to the Share Trustee to vote the Shares-in-Trust in
the manner in which the Share Trustee, in its sole and absolute discretion,
desires.

      (e) Designation of Permitted Transferee. The Share Trustee shall have the
exclusive and absolute right to designate a Permitted Transferee of any and all
Shares-in-Trust. In an orderly fashion so as not materially and adversely to
affect the Market Price of the Shares-in-Trust, the Share Trustee shall
designate any Person as Permitted Transferee; provided, however, that (i) the
Permitted Transferee so designated purchases for valuable consideration (whether
in a public or private sale), at a price as set forth in Section 16.2(g), the
Shares-in-Trust, and (ii) the Permitted Transferee so designated may acquire
such Shares-in-Trust without such acquisition resulting in a transfer to a Share
Trust and the redesignation of such shares of Equity Stock or Trust Securities
so acquired as Shares-in-Trust under Section 16.1(c). Upon the designation by
the Share Trustee of a Permitted Transferee in accordance with the provisions of
this Section 16.2(e), the Share Trustee of a Share Trust shall (w) cause to be
transferred to the Permitted Transferee that number of Shares-in-Trust acquired
by the Permitted Transferee, (x) cause to be recorded on the books of the
Corporation that the Permitted Transferee is the holder of record of such number
of shares of Equity Stock or amount of Trust Securities, (y) cause the
Shares-in-Trust to be cancelled, and (z) distribute to the Charitable
Beneficiary any and all amounts held with respect to the Shares-in-Trust after
making that payment to the Purported Record Transferee pursuant to Section
16.2(f).

                                       78


      (f) Compensation to Record Holder of Shares of Equity Stock or Trust
Securities that Become Shares-in-Trust. Any Purported Record Transferee shall be
entitled (following discovery of the Shares-in-Trust and subsequent designation
of the Permitted Transferee in accordance with Section 16.2(c)) to receive from
the Share Trustee upon the sale or other disposition of such Shares-in-Trust the
lesser of (i) in the case of (x) a purported Transfer in which the Purported
Record Transferee (or the Purported Beneficial Transferee, if applicable) gave
value for shares of Equity Stock or Trust Securities and which Transfer resulted
in the transfer of the shares to the Share Trust, the price per share, if any,
such Purported Record Transferee (or the Purported Beneficial Transferee, if
applicable) paid for the shares of Equity Stock or Trust Securities, or (z) a
Non-Transfer Event or Transfer in which the Purported Record Transferee (or the
Purported Beneficial Transferee, if applicable) did not give value for such
shares (e.g., if the shares were received through a gift or devise) and which
Non-Transfer Event or Transfer, as the case may be, resulted in the transfer of
shares to the Share Trust, the price per share or Trust Securities equal to the
Market Price on the date of such Non-Transfer Event or Transfer, and (ii) the
price per share received by the Share Trustee of the Share Trust from the sale
or other disposition of such Shares-in-Trust in accordance with Section 16.2(e)
or (g). Any amounts received by the Share Trustee in respect of such
Shares-in-Trust and in excess of such amounts to be paid the Purported Record
Transferee pursuant to this Section 16.2(f) shall be distributed to the
Charitable Beneficiary in accordance with the provisions of Section 16.2(e).
Each Charitable Beneficiary and Purported Record Transferee (and Purported
Beneficial Transferee, if different) waives any and all claims that each may
have against the Share Trustee and the Share Trust arising out of the
disposition of the Shares-in-Trust, except for claims arising out of the gross
negligence or willful misconduct of, or any failure to make payments in
accordance with this Section 16.2 by, such Share Trustee or the Corporation.

      (g) Purchase Rights in Shares-in-Trust. Shares-in-Trust shall be deemed to
have been offered for sale to the Corporation, or its designee, at a price per
share equal to the lesser of (i) the price per share in the transaction that
created such Shares-in-Trust (or, in the case of devise, gift or Non-Transfer
Event, the Market Price at the time of such devise, gift or Non-Transfer Event),
and (ii) the Market Price on the date the Corporation, or its designee, accepts
such offer. The Corporation shall have the right to accept such offer for a
period of ninety (90) days after the later of (x) the date of the Non-Transfer
Event or purported Transfer which resulted in such Shares-in-Trust and (y) the
date the Corporation determines in good faith that a Transfer or Non-Transfer
Event resulting in Shares-in-Trust has occurred, if the Corporation does not
receive a notice of such Transfer or Non-Transfer Event pursuant to Section
16.1(e).

                                       AND
                             9.75% COMMON SECURITIES
                   (LIQUIDATION AMOUNT $1,000.00 PER SECURITY)

      Pursuant to Section 7.1 of the Amended and Restated Declaration of Trust
of AHM Capital Trust I, dated as of June 28, 2007 (as amended from time to time,
the "Declaration"), the designation, rights, privileges, restrictions,
preferences and other terms and provisions of the Securities are set out below
(each capitalized term used but not defined herein has the meaning set forth in
the Declaration):

      1. Designation and Number.

            (a) Preferred Securities. 125,000 9.75% Preferred Securities of the
      Trust with an aggregate liquidation amount with respect to the assets of
      the Trust of One Hundred Twenty-Five Million Dollars ($125,000,000), and
      with a liquidation amount with respect to the assets of the Trust of
      $1,000.00 per security, are hereby designated for the purposes of
      identification only as Preferred Securities. The certificates evidencing
      the Preferred Securities shall be substantially in the form of Exhibit A-1
      to the Declaration, with such changes and additions thereto or deletions
      therefrom as may be required by ordinary usage, custom or practice.

            (b) Common Securities. Up to 3,866 9.75% Common Securities of the
      Trust with an aggregate liquidation amount with respect to the assets of
      the Trust of Three Million Eight Hundred Sixty-six Thousand Dollars
      ($3,866,000) and a liquidation amount with respect to the assets of the
      Trust of $1,000.00 per security, are hereby designated for the purposes of
      identification only as Common Securities. The certificates evidencing the
      Common Securities shall be substantially in the form of Exhibit A-2 to the
      Declaration, with such changes and additions thereto or deletions
      therefrom as may be required by ordinary usage, custom or practice.

      2. Distributions.

            (a) Distributions payable on each Security will be fixed (i) at a
      rate per annum of 9.75% (the "Coupon Rate") of the liquidation amount of
      $1,000.00 per Security (the "Liquidation Amount"), (ii) at the Coupon Rate
      on any overdue installment of Interest (to the extent that payment of such
      interest is enforceable under applicable law) and (iii) for any period of
      time during which any installment of Interest is overdue, at the Coupon
      Rate plus 2.00%, in every case, compounded quarterly, and each such rate
      being the equivalent rate of interest payable on the Debentures held by
      the Property Trustee. A Distribution is payable only to the extent that
      payments are made in respect of the Debentures held by the Property
      Trustee and to the extent the Property Trustee has funds on hand legally
      available therefor.

                                     A-I-1


            (b) Distributions on the Securities will be cumulative, will
      accumulate from the date of their original issuance, and will be payable
      quarterly in arrears on January 1, April 1, July 1 and October 1 of each
      year, commencing on October 1, 2007 (each, a "Distribution Date"), except
      as otherwise described below. Distributions will be computed on the basis
      of a 360-day year consisting of twelve 30-day months.

            (c) Distributions on the Securities (other than Distributions on a
      redemption date, if any) will be payable to the Holders thereof as they
      appear on the books and records of the Trust as of 5:00 p.m., New York
      City time, on the fifteenth (15th) day of the month, whether or not a
      Business Day, immediately preceding the month in which the relevant
      Distribution Date occurs, which Distribution Dates correspond to the
      interest payment dates on the Debentures. The relevant record dates for
      the Common Securities shall be the same as the record dates for the
      Preferred Securities. Distributions payable on any Securities that are not
      punctually paid on any Distribution Date, as a result of the Debenture
      Issuer having failed to make a payment under the Debentures, will cease to
      be payable to the Holder on the relevant record date, and such defaulted
      Distribution will instead be payable to the Person in whose name such
      Securities are registered on the special record date or other specified
      date determined in accordance with the Indenture. If any date on which
      Distributions are payable on the Securities is not a Business Day, then
      payment of the Distribution payable on such date will be made on the next
      succeeding day that is a Business Day (and without any interest or other
      payment in respect of any such delay), except that if such next succeeding
      Business Day is in the next succeeding calendar year, such payment shall
      be made on the immediately preceding Business Day with the same force and
      effect as if made on such date.

            (d) As used in this Annex I, the term "Distribution," unless
      otherwise stated, includes regular quarterly Distributions payable at the
      Coupon Rate (or such other rate pursuant to paragraph 2(a) above) as well
      as Distributions payable in accordance with Article VI of the Declaration
      if and to the extent that the Debenture Issuer makes a payment of Interest
      on the Debentures in respect of Liquidated Damages and/or Additional Sums.

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

      3. Liquidation Distribution Upon Termination.

      In the event of any termination of the Trust other than upon the
occurrence of events specified in Sections 8.1(a)(v), (vi), (viii) or 8(a)(ix)
of the Declaration, or if the Initial Purchaser of Common Securities otherwise
gives notice of its election to liquidate the Trust pursuant to Section
8.1(a)(iii) of the Declaration, the Trust shall be liquidated by the
Administrative Trustees as expeditiously as the Administrative Trustees
determine to be possible by distributing to the Holders, after satisfaction of
liabilities to creditors of the Trust as provided by applicable law, a Like
Amount (as defined below) of the Debentures, unless such distribution is
determined by the

                                     A-I-2


Property Trustee not to be practicable, in which event such Holders will be
entitled to receive Pro Rata out of the assets of the Trust legally available
for distribution to Holders an amount in cash or immediately available funds
equal to the aggregate of the liquidation amount of $1,000.00 per Security plus
accumulated and unpaid Distributions thereon to the date of payment, after
satisfaction of liabilities to creditors of the Trust as provided by applicable
law (such amount being the "Liquidation Distribution"). If the Debentures are
distributed to the holders of the Preferred Securities, the Debenture Issuer
will use its reasonable efforts to cause the Debentures to be listed on the
market or exchange on which the Preferred Securities are then listed, if any.

      "Like Amount" means (i) with respect to a redemption of the Securities,
Securities having a Liquidation Amount equal to the principal amount of
Debentures to be paid in accordance with their terms and (ii) with respect to a
distribution of Debentures upon the liquidation of the Trust, Debentures having
a principal amount equal to the Liquidation Amount of the Securities of the
Holder to whom such Debentures are distributed.

      If, upon any such liquidation, the Liquidation Distribution can be paid
only in part because the Trust has insufficient assets on hand legally 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 except
that if an Event of Default shall exist under the Indenture, the Preferred
Securities shall have a priority over the Common Securities.

      On and from the date fixed by the Administrative Trustees for any
distribution of Debentures and liquidation of the Trust: (i) the Securities will
no longer be deemed to be outstanding, (ii) the Clearing Agency or its nominee
(or any successor Clearing Agency or its nominee), as the Holder of the
Preferred Securities, will receive a registered global certificate or
certificates representing the Debentures to be delivered upon such distribution,
and (iii) any certificates representing Securities not held by the Clearing
Agency or its nominee (or any successor Clearing Agency or its nominee) will be
deemed to represent beneficial interests in a Like Amount of Debentures bearing
an interest rate identical to the distribution rate of those Preferred
Securities, and bearing accrued and unpaid interest in an amount equal to the
accumulated and unpaid Distributions on those Preferred Securities until such
certificates are presented to the Debenture Issuer or its agent for transfer or
reissue.

      4. Redemption and Distribution.

            (a) Upon the repayment of the Debentures in whole or in part, at
      maturity or otherwise (regardless of whether at the option of the
      Debenture Issuer in accordance with the provisions of paragraph 4(c)
      below, pursuant to a Special Event, as described below, or pursuant to a
      Change in Control, as defined in the Indenture), the proceeds from such
      redemption shall be simultaneously applied by the Property Trustee
      (subject to the Property Trustee having received written notice no later
      than thirty (30) days prior to such redemption) to redeem a Like Amount of
      the Securities, at the Redemption Price (as defined below), the Change in
      Control Redemption Price (as defined below) or the Make-Whole Redemption
      Price (as defined below), as applicable. If fewer than all of the
      Debentures are redeemed on a redemption date, then the Property Trustee
      shall allocate the proceeds of the redemption on a Pro Rata basis among
      the Preferred Securities and

                                     A-I-3


      the Common Securities unless an Event of Default shall have occurred, in
      which case no proceeds shall be allocated to the Common Securities until
      the Preferred Securities are paid in full.

            (b) (i) The "Redemption Price," with respect to a redemption of
      Securities, shall mean an amount equal to 100% of the Liquidation Amount
      of Securities to be redeemed, plus accrued and unpaid Distributions on the
      Securities, if any, to the date of such redemption.

                  (ii) The "Make-Whole Redemption Price" shall mean the sum of
            (A) the Redemption Price and (B) the Make-Whole Payment Price (as
            defined in the Indenture).

                  (iii) The "Change in Control Redemption Price" shall mean the
            greater of: (x) the Redemption Price plus the Change in Control
            Redemption Premium, or (y) an amount equal to the number of shares
            of Common Stock that would be issued if such Debentures were
            converted on the Change in Control Effective Date at the then
            prevailing Conversion Rate multiplied by the Stock Price (as defined
            in the Indenture) plus the Change in Control Redemption Premium.

                  (iv) If fewer than all the outstanding Securities are to be so
            redeemed, the Securities to be redeemed will be determined as
            described in paragraph 5(a)(ii) below.

            (c) The Debenture Issuer may redeem the Debentures, subject to
      conditions set forth in the Indenture, prior to maturity, in whole or in
      part, on one or more occasions. Subject to the provisions of paragraph
      4(d) and 4(e) below, the Debentures shall not be redeemable at the option
      of the Debenture Issuer prior to July 1, 2010. The Debenture Issuer shall
      have the right to redeem the Debentures, in whole or in part, on one or
      more occasions at any time on or after July 1, 2010, at the Make-Whole
      Redemption Price, if the average Closing Price (as defined in the
      Indenture) per share of Common Stock for the ten (10) consecutive Trading
      Days (as defined in the Indenture) ending on the Trading Day prior to the
      mailing of the notice of redemption exceeds 130% of the then prevailing
      Conversion Price (as defined in the Indenture). On and after July 1, 2012,
      the Debenture Issuer shall have the right to redeem the Debentures, in
      whole or in part, at the Redemption Price.

            (d) If at any time an Investment Company Event or a Tax Event (each
      as defined below, and each a "Special Event") occurs, the Debenture Issuer
      shall have the right (subject to the conditions set forth in the
      Indenture) at any time to redeem, at the Redemption Price, the Debentures
      in whole, but not in part, following the occurrence of such Special Event.

      "Investment Company Event" means the Initial Purchaser of Common
Securities and the Trust shall have received an opinion of independent
securities counsel experienced in such matters to the effect that, as a result
of (i) any amendment to, or change (including any announced prospective change)
in, any laws or regulations of the United States or any rules,

                                     A-I-4


guidelines or policies of any applicable regulatory agency or authority; or (ii)
any official administrative pronouncement or judicial decision interpreting or
applying such laws or regulations, which amendment or change is effective or
which pronouncement or decision is announced on or after the date the Preferred
Securities are first issued, the Trust is, or within ninety (90) days of the
date of the opinion will be, considered an investment company that is required
to be registered under the Investment Company Act.

      "Tax Event" means the receipt by the Debenture Issuer of an opinion of
independent counsel experienced in such matters to the effect that, as a result
of (a) any amendment to or change (including any announced prospective change)
in the laws or any regulations thereunder of the United States or any political
subdivision or taxing authority thereof or therein or (b) any judicial decision
or any official administrative pronouncement or regulatory procedure, including
any notice or announcement of intent to adopt any such pronouncement (including
any private letter ruling, technical advice memorandum or field service advice)
or procedure (an "Administrative Action"), regardless of whether such judicial
decision or Administrative Action is issued to or in connection with a
proceeding involving the Debenture Issuer or the Trust and whether or not
subject to review or appeal, which amendment, change, judicial decision or
Administrative Action is enacted, promulgated or announced, in each case, on or
after the date of issuance of the Preferred Securities, there is more than an
insubstantial risk that (i) the Trust is, or will be within ninety (90) days of
the date of such opinion, subject to United States federal income tax with
respect to income received or accrued on the Debentures, (ii) interest payable
by the Debenture Issuer on the Debentures is not, or within ninety (90) days of
the date of such opinion, will not be, deductible by the Debenture Issuer, in
whole or in part, for United States federal income tax purposes, or (iii) the
Trust is, or will be within ninety (90) days of the date of such opinion,
subject to more than a de minimis amount of other taxes, duties or other
governmental charges.

            (e) If at any time there occurs a Change in Control, the Debenture
      Issuer shall have the right (subject to the conditions set forth in the
      Indenture) at any time to redeem, at the Redemption Price plus, under
      certain circumstances described in the Indenture, a Change in Control
      Redemption Premium, the Debentures in whole, but not in part, following
      the occurrence of such Change in Control.

            (f) Upon any redemption of Debentures upon the occurrence of a
      Special Event or a Change in Control and in compliance with the Indenture,
      the Trust will, simultaneous with such redemption of Debentures, cause all
      of the Securities to be redeemed by the Trust at the price equivalent to
      that paid to redeem the Debentures.

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

            (h) In connection with any redemption of Securities, the Trust may
      arrange for the purchase and conversion of any Securities by an agreement
      with one or more investment bankers or other purchasers to purchase such
      Securities by paying to the Property Trustee in trust for the Holders, on
      or before the redemption date, an amount not less than the applicable
      Redemption Price, the Change in Control Redemption Price or

                                     A-I-5


      Make-Whole Redemption Price, as the case may be, of such Securities.
      Notwithstanding anything to the contrary contained in this paragraph 4,
      the obligation of the Trust to pay the redemption price of such Securities
      shall be deemed to be satisfied and discharged only to the extent such
      amount is so paid by such purchasers. If such an agreement is entered
      into, a copy of which shall be filed with the Property Trustee prior to
      the redemption date, any Securities not duly surrendered for conversion by
      the Holders thereof, may, at the option of the Trust, be deemed, to the
      fullest extent permitted by law, acquired by such purchasers from such
      Holders and (notwithstanding anything to the contrary contained in
      paragraph 6 of this Annex I) surrendered by such purchasers for
      conversion, all as of immediately prior to the close of business on the
      redemption date (and the right to convert any such Securities shall be
      deemed to have been extended through such time), subject to payment of the
      above amount as aforesaid. At the written direction of the Trust, the
      Property Trustee shall hold and dispose of any such amount paid to it in
      the same manner as it would monies deposited with it by the Trust for the
      redemption of Securities. Without the Property Trustee's prior written
      consent, no arrangement between the Trust and such purchasers for the
      purchase and conversion of any Securities shall increase or otherwise
      affect any of the powers, duties, responsibilities or obligations of the
      Property Trustee as set forth in the Declaration, and the Debenture Issuer
      and the Trust agree to indemnify the Property Trustee from, and hold it
      harmless against, any and all loss, liability or expense arising out of or
      in connection with any such arrangement for the purchase and conversion of
      any Securities between the Trust and such purchasers, including the costs
      and expenses incurred by the Property Trustee in the defense of any claim
      or liability arising out of or in connection with the exercise or
      performance of any of its powers, duties, responsibilities or obligations
      under the Declaration. Nothing in the preceding sentence shall be deemed
      to limit the rights, privileges, immunities and protections afforded to
      the Property Trustee in the Declaration. Nothing in this paragraph 4(h)
      shall affect the right of the Holders to receive the full Redemption
      Price, the Change in Control Redemption Price or Make-Whole Redemption
      Price, as the case may be, on the redemption date.

      5. Procedures Related to Redemptions or Distributions of Securities.

            (a) The procedure with respect to redemptions or distributions of
      Securities shall be as follows:

                  (i) (A) Notice of any redemption due to a Change in Control
            will be given by the Trust as promptly as practicable following the
            Date the Debenture Issuer publicly announces a Change in Control but
            in no event less than twenty (20) Business Days Prior to the
            anticipated effective date of such Change in Control and (B) notice
            of any redemption (other than due to a Change in Control) of, or
            notice of distribution of Debentures in exchange for, the Securities
            will be given by the Trust by mail to each Holder to be redeemed or
            exchanged not fewer than thirty (30) nor more than sixty (60) days
            before the date fixed for redemption or exchange thereof or which,
            in the case of a redemption under this paragraph 5(a)(i)(B), will be
            the date fixed for redemption of the Debentures (any such notice
            provided pursuant to clause (A) or (B) of this paragraph 5(a)(i)
            shall be referred to as (a "Redemption/Distribution Notice"). For
            purposes of the calculation of the

                                     A-I-6


            date of redemption or exchange and the dates on which notices are
            given pursuant to this paragraph 5(a)(i), a Redemption/Distribution
            Notice shall be deemed to be given on the day such notice is first
            mailed by first-class mail, postage prepaid, to Holders. Each
            Redemption/Distribution Notice shall be addressed to the Holders at
            the address of each such Holder appearing in the books and records
            of the Trust. The notice if mailed in the manner herein provided
            shall be conclusively presumed to have been duly given, whether or
            not the Holder receives such notice. In any case, failure to give
            such notice or any defect in the Redemption/Distribution Notice to
            the Holder of any Security designated for redemption or exchange as
            a whole or in part shall not affect the validity of the redemption
            or exchange proceedings with respect to any other Security.

                  (ii) Subject to paragraph 4(a), in the event that fewer than
            all the outstanding Securities are to be redeemed, the particular
            Securities to be redeemed shall be selected on a Pro Rata basis
            (based upon Liquidation Amounts) not more than sixty (60) days prior
            to the date fixed for redemption from the outstanding Securities not
            previously called for redemption, provided, however, that with
            respect to Holders that would be required to hold less than five (5)
            but more than zero Securities as a result of such Pro Rata
            redemption, the Trust shall redeem Securities of each such Holder so
            that after such redemption such Holder either shall hold five (5)
            Securities or such Holder shall no longer hold any Securities, and
            shall use such method (including, without limitation, by lot) as the
            Trust shall deem fair and appropriate, provided further, that any
            such proration may be made on the basis of the aggregate Liquidation
            Amount of Securities held by each Holder thereof and may be made by
            making such adjustments as the Trust deems fair and appropriate in
            order that only Securities in denominations of $1,000.00 or integral
            multiples thereof shall be redeemed. In respect of Preferred
            Securities registered in the name of and held of record by the
            Clearing Agency or its nominee (or any successor Clearing Agency or
            its nominee) or any nominee, the distribution of the proceeds of
            such redemption will be made to the Clearing Agency and disbursed by
            such Clearing Agency in accordance with the procedures applied by
            such agency or nominee.

                  (iii) If Securities are to be redeemed and the Trust gives a
            Redemption/ Distribution Notice (which notice will be irrevocable),
            then (A) with respect to Preferred Securities issued in book-entry
            form if (i) following the occurrence of a Special Event, by 1:00
            p.m., New York City time, on the redemption date or at such earlier
            time as the Trust determines, or (ii) following the occurrence of a
            Change in Control, by 1:00 p.m., New York City time on the fifth
            (5th) Business Day following the Change in Control Effective Date or
            such earlier time as the Trust determines, provided in either case
            that the Debenture Issuer has paid the Debenture Trustee a
            sufficient amount of cash in connection with the related redemption
            or maturity of the Debentures by 10:00 a.m., New York City time, on
            the maturity date or the date of redemption, as the case requires,
            the Property Trustee will deposit irrevocably with the Clearing
            Agency or its nominee (or successor Clearing Agency or its nominee)
            funds sufficient to pay the Redemption Price, the Change in Control
            Redemption Price or the Make-Whole Redemption

                                     A-I-7


            Price, as the case may be, with respect to such Preferred Securities
            and will give the Clearing Agency irrevocable instructions and
            authority to pay the Redemption Price, the Change in Control
            Redemption Price or the Make-Whole Redemption Price, as the case may
            be, to the relevant Clearing Agency Participants and (B) with
            respect to Preferred Securities issued in certificated form and
            Common Securities, the Property Trustee will irrevocably deposit
            with the Paying Agent funds sufficient to pay the Redemption Price,
            the Change in Control Redemption Price or the Make-Whole Redemption
            Price, as the case may be, and will give the Paying Agent
            irrevocable instructions and authority to pay the Redemption Price,
            the Change in Control Redemption Price or the Make-Whole Redemption
            Price, as the case may be, to Holders upon surrender of their
            certificates evidencing the Preferred Securities or Common
            Securities, as the case may be. If a Redemption/Distribution Notice
            shall have been given and funds deposited as required, if
            applicable, then immediately prior to the close of business on the
            redemption date, Distributions will cease to accumulate on the
            Securities so called for redemption and all rights of Holders so
            called for redemption will cease, except the right of the Holders of
            such Securities to receive the Redemption Price, the Change in
            Control Redemption Price or the Make-Whole Redemption Price, as the
            case may be, but without interest on such Redemption Price, the
            Change in Control Redemption Price or the Make-Whole Redemption
            Price, as the case may be, and such Securities shall cease to be
            outstanding.

                  (iv) Notwithstanding the foregoing, payment of accumulated and
            unpaid Distributions on the Redemption Date of the Securities will
            be subject to the rights of Holders on the close of business on the
            relevant record date in respect of a Distribution Date occurring on
            or prior to such Redemption Date.

      The Trust shall not be required to: (i) issue, register the transfer of or
exchange any Securities during a period beginning at the opening of business
fifteen (15) days before the day of mailing of a notice of redemption and ending
at the close of business on the day of such mailing or (ii) register the
transfer of or exchange any Securities selected for redemption in whole or in
part except, in the case of any Securities being redeemed in part, any portion
thereof not to be redeemed; for the avoidance of doubt, none of the transfer and
exchange provisions shall affect the Debenture Issuer's obligation to comply
with the provisions of Section 17.01 of the Indenture and paragraph 6 below. If
any date fixed for redemption of Securities is not a Business Day, then payment
of the Redemption Price, the Change in Control Redemption Price or the
Make-Whole Redemption Price, as the case may be, payable on such date will be
made on the next succeeding day that is a Business Day (and without any interest
or other payment in respect of any such delay) except that, if such next
succeeding Business Day falls in the next calendar year, such payment shall be
made on the immediately preceding Business Day, in each case with the same force
and effect as if made on such date fixed for redemption. If payment of the
Redemption Price, the Change in Control Redemption Price or the Make-Whole
Redemption Price, as the case may be, in respect of any Securities is improperly
withheld or refused and not paid either by the Trust or by the Debenture Issuer
as guarantor pursuant to the Guarantee Agreement, Distributions on such
Securities will continue to accumulate at the rate prescribed therefor in the
Security 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

                                     A-I-8


calculating the Redemption Price, the Change in Control Redemption Price or the
Make-Whole Redemption Price, as the case may be.

                  (v) Redemption/Distribution Notices shall be sent by the
            Property Trustee on behalf of the Trust at the expense of the
            Initial Purchaser of Common Securities to (A) in respect of the
            Preferred Securities, the Clearing Agency or its nominee (or any
            successor Clearing Agency or its nominee) if the Global Certificates
            have been issued or, if Certificated Preferred Security Certificates
            have been issued, to the Holder thereof, and (B) in respect of the
            Common Securities to the Holder thereof.

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

      6. Conversion Rights.

      The Holders of Preferred Securities shall have the right at any time on or
after the occurrence of the events described in Section 17.01 of the Indenture
and prior to 5:00 p.m., New York City time, on the Business Day immediately
preceding the date of repayment of such Preferred Securities, whether at stated
maturity or upon redemption, at their option to cause the Conversion Agent to
convert Preferred Securities, on behalf of the converting Holders, into shares
of Common Stock, in the manner described herein on and subject to the following
terms and conditions:

            (a) The Preferred Securities will be exchangeable for Debentures
      which will be convertible at the office of the Conversion Agent into fully
      paid and nonassessable shares of Common Stock pursuant to the Holder's
      direction to the Conversion Agent to exchange such Preferred Securities
      for a portion of the Debentures theretofore held by the Trust on the basis
      of one Preferred Security per $1,000.00 principal amount of Debentures,
      and immediately convert such amount of Debentures into fully paid and
      nonassessable shares of Common Stock at an initial conversion rate of
      39.1016 shares of Common Stock for each $1,000.00 principal amount of
      Debentures (equal to an initial Conversion Price of $25.57 per share of
      Common Stock), subject to adjustment as described in the Indenture (the
      "Conversion Rate"). In addition, upon the occurrence of a Change in
      Control, holders converting Debentures in connection with such Change in
      Control within the meaning of the Indenture (including Holders directing
      the Conversion Agent) shall, under certain circumstances, be entitled to
      receive a make whole premium in the form of an increase in the Conversion
      Rate, as and to the extent set forth in the Indenture.

            On each Conversion Rate Reset Date, the Conversion Rate will be
      reset to the lower of (x) the Conversion Rate then in effect, and (y) a
      Conversion Rate determined by dividing $1,000 by an amount equal to 120%
      of the Average Closing Price (as defined in the Indenture).
      Notwithstanding the foregoing, if the application of the foregoing were to

                                     A-I-9


      result in the Conversion Rate being reset to a Conversion Rate that would
      be greater than the Maximum Conversion Rate, then the Conversion Rate will
      instead be reset to the Maximum Conversion Rate. The Maximum Conversion
      Rate shall be subject to adjustment on each occasion on which the
      Conversion Rate shall be adjusted (other than on account of adjustments to
      the Conversion Rate resulting from the application of the provisions of
      this paragraph) by multiplying the then applicable Maximum Conversion Rate
      by a fraction, the numerator of which is the Conversion Rate as so
      adjusted and the denominator of which is the Conversion Rate in effect
      immediately prior to such adjustment; provided that the Maximum Conversion
      Rate as so adjusted shall in no event be greater than 65.1693 shares per
      $1,000.00 principal amount of Securities, subject to adjustment on account
      of the events specified in Section 17.03(a) of the Indenture. The
      Conversion Rate shall be adjusted in certain instances as provided in
      paragraphs (a), (b), (c), (d) or (e) of Section 17.03 of the Indenture.
      Notwithstanding the forgoing, in no event will the Conversion Rate or
      Maximum Conversion Rate be adjusted as described in Section 17.01(a) or
      17.03(d) of the Indenture to a Conversion Rate that is greater than the
      Maximum Cash Adjusted Conversion Rate.

            Upon conversion of Debentures following the Holder's direction to
      the Conversion Agent, the Debenture Issuer shall, in accordance with the
      provisions of the Indenture, have the right to deliver, in lieu of Common
      Stock, cash in lieu of all or a portion of such Common Stock. The
      Debenture Issuer shall inform the Property Trustee of its election to pay
      cash for all or a portion of the shares in lieu of delivery of the shares
      of Common Stock otherwise issuable upon conversion (and, if applicable,
      the percentage of each share of Common Stock that will be paid in cash in
      lieu of shares of Common Stock) and the Property Trustee shall upon
      receipt of such notice notify Holders who have surrendered their Preferred
      Securities for conversion no later than two (2) Business Days after the
      Conversion Date.

            If the Debenture Issuer shall have elected, unilaterally and
      irrevocably, to settle its obligation to deliver shares of Common Stock
      with respect to Debentures converted following such election, in cash and,
      if applicable, shares of common stock ("Net Share Settlement Election"),
      then upon conversion of Debentures following the Holder's direction to the
      Conversion Agent, the Debenture Issuer shall deliver to the holder
      surrendering such Debentures for conversion an amount in cash equal to the
      lesser of (i) the principal amount of the Debentures so converted and (ii)
      the Conversion Value, determined in the manner set forth in the Indenture.
      If the Conversion Value exceeds the principal amount of the Debentures on
      the conversion date, the Debenture Issuer will also deliver, at its
      election, cash or Common Stock or a combination of cash and Common Stock
      for the Conversion Value in excess of the principal amount of the
      Debentures so converted. On any day prior to the first Trading Day of the
      applicable Conversion Reference Period, the Debenture Issuer may specify
      the Cash Percentage (as defined in the Indenture) and the Debenture Issuer
      shall notify the Property Trustee who shall forthwith and immediately
      notify the Holder of such Cash Percentage.

            (b) In order to convert Preferred Securities into Common Stock the
      Holder shall submit to the Conversion Agent at the office referred to
      above a request to convert Preferred Securities on behalf of such Holder
      substantially in the form attached to Exhibit

                                     A-I-10


      A-1 to the Declaration (the "Conversion Request"), together, if the
      Preferred Securities are in certificated form, with such certificates. The
      Holder must furnish appropriate endorsements or transfer documents, if
      required by the Conversion Agent, and pay any transfer or similar tax, if
      required. The Trust shall not cause the conversion of any Debentures
      except pursuant to such a Conversion Request. The Conversion Request shall
      (i) set forth the number of Preferred Securities to be converted and the
      name or names, if other than the Holder, in which the shares of Common
      Stock should be issued and (ii) direct the Conversion Agent (a) to
      exchange such Preferred Securities for a portion of the Debentures held by
      the Trust having a principal amount equal to the Liquidation Amount of the
      Preferred Securities to be converted and (b) to immediately convert such
      Debentures on behalf of such Holder, into Common Stock at the conversion
      rate applicable to the Debentures at such time. The Conversion Agent shall
      notify the Property Trustee of the Holder's election to exchange Preferred
      Securities for a portion of the Debentures held by the Trust and the
      Property Trustee shall, upon receipt of such notice, deliver to the
      Conversion Agent the appropriate principal amount of Debentures for
      exchange in accordance with this paragraph 6. The Conversion Agent shall
      thereupon notify the Initial Purchaser of Common Securities of the
      Holder's election to convert such Debentures into shares of Common Stock.

            (c) Except as described herein, no distribution will be payable on
      Preferred Securities surrendered for conversion with respect to any
      Distribution Date subsequent to the date of conversion and neither the
      Trust nor the Debenture Issuer will make, or be required to make, any
      payment, allowance or adjustment for accumulated and unpaid Distributions,
      whether or not in arrears, on Preferred Securities surrendered for
      conversion. If any Preferred Securities are surrendered for conversion
      between the period from 5:00 p.m., New York City time, on any record date
      through and including the related Distribution Date, the Preferred
      Securities surrendered for conversion must be accompanied by payment from
      the Holder in next day funds of an amount equal to the Distribution which
      the registered holder on such record date is to receive, and such
      registered holder shall be entitled to receive the Distribution payable on
      the subsequent Distribution Date on the portion of Preferred to be
      converted, notwithstanding the conversion thereof prior to such
      Distribution Date. The previous sentence shall not apply in the case of
      Preferred Securities called for redemption on a redemption date between a
      record date and a related Distribution Date as described in the next
      sentence. If notice of redemption of Preferred Securities is mailed or
      otherwise given to Holders, then such converting Holder shall be entitled
      to receive either (i) if the date of such conversion falls after a record
      date and on or prior to the next succeeding Distribution Date, all accrued
      and unpaid Distributions on such Securities to such Distribution Date, or
      (ii) if the date of such conversion does not fall on a date described in
      clause (i) above, all accrued and unpaid Distributions on such Securities
      to the most recent Distribution Date prior to the date of such conversion
      (even though no Distributions were paid on such date), which Distributions
      shall, in either such case, be paid to such converting Holder unless
      another Holder was the record owner of such Securities as of 5:00 p.m.,
      New York City time on the record date for which such Distribution payment
      is made, in which case such Distribution payment shall be paid to such
      other Holder. Except as otherwise set forth above in this paragraph, in
      the case of any Security which is converted, Distributions which are
      payable after the date of conversion of such Preferred Security shall not
      be

                                     A-I-11


      payable, and the Trust shall not make nor be required to make any other
      payment, adjustment or allowance with respect to accrued but unpaid
      Distributions on the Securities being converted, which shall be deemed to
      be paid in full through delivery of the Common Stock (together with the
      cash payment, if any, in lieu of fractional shares) or cash-in-lieu of
      delivering Common Stock, or any combination elected by the Debenture
      Issuer. If any Preferred Security called for redemption is converted, any
      money deposited with the Property Trustee or with any paying agent or so
      segregated and held in trust for the redemption of such Preferred Security
      shall (subject to any right of the Holder) be paid to the Trust upon a
      written request or, if then held by the Trust, shall be discharged from
      such trust.

            In addition to the provisions of the foregoing paragraph, in the
      event that the Debenture Issuer shall have called the Debentures for
      redemption and the Trust shall have converted some or all of its
      Debentures due to a Holder of Preferred Securities having exercised its
      right under the Indenture to exchange such Preferred Securities for
      Debentures, in addition to the amounts owing upon conversion pursuant to
      the provisions of this paragraph and Article XVII of the Indenture, the
      Holder of such Preferred Securities shall also be entitled to receive, on
      the date on which such amounts are deliverable, a cash amount equal to the
      Make-Whole Payment Price or the Change in Control Redemption Premium, as
      the case may be, if any such Make-Whole Payment Price or Change in Control
      Redemption Premium shall then be owing in connection with the Debentures.

            Each conversion shall be deemed to have been effected immediately
      prior to 5:00 p.m., New York City time, on the Business Day on which the
      Conversion Request and any other required deliverables were received (the
      "Conversion Date") by the Conversion Agent from the Holder. The Person or
      Persons entitled to receive the Common Stock issuable upon such conversion
      shall be treated for all purposes as the record holder or holders of such
      Common Stock as of the Conversion Date. As promptly as practicable on or
      after the Conversion Date, the Debenture Issuer shall issue and deliver at
      the office of the Conversion Agent, unless otherwise directed by the
      Holder in the Conversion Request, a certificate or certificates for the
      number of full shares of Common Stock issuable upon such conversion,
      together with the cash payment, if any, in lieu of any fraction of any
      share to the Person or Persons entitled to receive the same. The
      Conversion Agent shall distribute such certificate or certificates to such
      Person or Persons.

            (d) Subject to any right of the Holder, the fair market value of the
      fixed number of shares of Common Stock into which the Preferred Securities
      are convertible (together with the cash payment, if any, in lieu of
      fractional shares) shall be treated as issued, to the extent thereof, (i)
      first, in exchange for accrued and unpaid Distributions on such Preferred
      Securities at the time of such conversion, and (ii) second, the balance,
      if any, of such fair market value of such Common Stock (and any cash
      payment) shall be treated as issued in exchange for the liquidation amount
      of the portion of Preferred Securities so converted.

                                     A-I-12


            (e) Subject to the next succeeding sentence, no fractional shares of
      Common Stock shall be issued as a result of conversion, but in lieu
      thereof, the Debenture Issuer shall pay to the Conversion Agent a cash
      adjustment in an amount equal to the same fraction of the Closing Price of
      such fractional interest on the date on which the Preferred Securities or
      Debentures, as the case may be, were duly surrendered to the Conversion
      Agent for conversion, or, if such day is not a Trading Day, on the next
      Trading Day, and the Conversion Agent in turn shall make such payment, if
      any, to the Holder of the Debentures so converted. In the event that the
      Debenture Issuer shall have made a Net Share Settlement Election, a Holder
      otherwise entitled to a fractional share shall receive cash equal to the
      applicable portion of the arithmetic average of the volume weighted
      average price of the Common Stock for each of the five (5) consecutive
      Trading Days of the Conversion Reference Period.

            (f) In the event of the conversion of any Preferred Security in part
      only, a new Preferred Security or Preferred Securities for the unconverted
      portion thereof shall be issued in the name of the Holder thereof upon the
      cancellation thereof in accordance with Section 7.10 of the Declaration.

            (g) In effecting the conversion transactions described in this
      paragraph 6, the Conversion Agent shall be acting as agent of the Holders
      of Preferred Securities (in the exchange of Preferred Securities for
      Debentures) and as agent of the Debenture holders (in the conversion of
      Debentures into Common Stock), as the case may be, directing it to effect
      such conversion transactions. The Conversion Agent is hereby authorized
      (i) to exchange Preferred Securities for Debentures held by the Trust from
      time to time in connection with the conversion of such Preferred
      Securities in accordance with this paragraph 6 and the applicable
      provisions of the Indenture and (ii) to convert all or a portion of the
      Debentures into Common Stock and thereupon to deliver such shares of
      Common Stock in accordance with the provisions of this paragraph 6 and the
      applicable provisions of the Indenture and to deliver to the Trust a new
      Debenture or Debentures for any resulting unconverted principal amount.

            (h) Any certificates representing shares of Common Stock issuable
      upon exchange of the Preferred Securities for Debentures and conversion of
      such Debentures shall bear any legend required by Section 2.06 of the
      Indenture.

            (i) The Debenture Issuer shall at all times reserve and keep
      available out of its authorized and unissued Common Stock, solely for
      issuance upon the conversion of the Debentures, free from any preemptive
      or other similar rights, such number of shares of Common Stock as shall
      from time to time be issuable upon the conversion of all the Debentures
      then outstanding. Notwithstanding the foregoing, the Debenture Issuer
      shall be entitled to deliver upon conversion of Debentures, shares of
      Common Stock reacquired and held in the treasury of the Initial Purchaser
      of Common Securities (in lieu of the issuance of authorized and unissued
      shares of Common Stock), so long as any such treasury shares are free and
      clear of all liens, charges, security interests or encumbrances. Any
      shares of Common Stock issued upon conversion of the Debentures shall be
      duly authorized, validly issued and fully paid and nonassessable. The
      Property Trustee shall deliver the shares of Common Stock received upon
      conversion of the Debentures to the

                                     A-I-13


      converting Holder free and clear of all liens, charges, security interests
      and encumbrances, except for United States withholding taxes and back-up
      withholding taxes.

      7. Purchase Right Following Change In Control or Termination of Trading.

            (a) If a Change in Control or Termination of Trading occurs, each
      holder of a Preferred Security will have the right to exchange any or all
      of such Holder's Preferred Securities for Debentures of a Like Amount and
      to simultaneously require the Debenture Issuer to repurchase such
      Debentures on the Repurchase Date (as defined in the Indenture) at a
      repurchase price in cash equal to 100% of the principal amount of the
      Debentures that have been exchanged for such Holder's Preferred
      Securities, plus accrued and unpaid interest on such Debentures to, but
      excluding, the Repurchase Date.

            (b) As promptly as practicable following either (i) the date the
      Debenture Issuer publicly announces a Change in Control or (ii) the date
      on which a Termination of Trading occurs, but, in the case of a Change in
      Control, not less than twenty (20) Business Days prior to the anticipated
      effective date of such Change in Control, the Debenture Issuer must give
      notice to each Holder of a Preferred Security and the Property Trustee of
      the transaction that constitutes the Change in Control or Termination of
      Trading and of the resulting repurchase right, which notice must specify
      the Repurchase Date. To exercise the repurchase right, a Holder must
      deliver written notice to the Debenture Issuer, the Trust and the Property
      Trustee of the Holder's exercise of its repurchase right no later than the
      second (2nd) Business Day prior to the Repurchase Date. Pursuant to the
      Holder's notice to the Property Trustee, the Holder will direct the
      Property Trustee, in its capacity as exchange agent (the "Exchange Agent")
      to exchange such Preferred Securities for a portion of the Debentures
      theretofore held by the Trust on the basis of one Preferred Security per
      $1,000.00 principal amount of Debentures, and immediately exercise the
      right in respect of such Debentures to require the Debenture issuer to
      repurchase such Debentures on the Repurchase Date for cash at a purchase
      price of $1,000.00 plus accrued and unpaid interest to the Repurchase Date
      for each $1,000.00 principal amount of Debentures so tendered for
      repurchase.

            (c) In order to exercise the right to require the Debenture Issuer
      to repurchase the Holder's Debentures following the exchange of Preferred
      Securities for Debentures, the Holder shall submit to the Exchange Agent
      at the office referred to above a request to repurchase Preferred
      Securities on behalf of such Holder substantially in the form attached to
      Exhibit A-1 to the Declaration (the "Notice of Repurchase Election"),
      together, if the Preferred Securities are in certificated form, with such
      certificates. The Holder must furnish appropriate endorsements or transfer
      documents, if required by the Exchange Agent, and pay any transfer or
      similar tax, if required. The Trust shall not cause the repurchase of any
      Debentures except pursuant to such a Notice of Repurchase Election. The
      Notice of Repurchase Election shall (i) set forth the number of Preferred
      Securities to be repurchased and (ii) direct the Exchange Agent (a) to
      exchange such Preferred Securities for a portion of the Debentures held by
      the Trust having a principal amount equal to the Liquidation Amount of the
      Preferred Securities to be repurchased and (b) to immediately exercise the
      repurchase right with respect to such Debentures on

                                     A-I-14


      behalf of such Holder. The Exchange Agent (if other than the Property
      Trustee) shall notify the Property Trustee of the Holder's election to
      exchange Preferred Securities for a portion of the Debentures held by the
      Trust and the Property Trustee shall, upon receipt of such notice, deliver
      to the Exchange Agent the appropriate principal amount of Debentures for
      exchange in accordance with this paragraph 7. The Exchange Agent shall
      thereupon notify the Debenture Issuer of the Holder's election to require
      the Debenture Issuer to repurchase such Debentures in accordance with the
      provisions of the Indenture.

            (d) In the event of the exercise of the repurchase right of any
      Preferred Security in part only, a new Preferred Security or Preferred
      Securities for the portion thereof in respect of which the repurchase
      right shall not have been exercised shall be issued in the name of the
      Holder thereof upon the cancellation thereof in accordance with Section
      7.10 of the Declaration.

            (e) In effecting the repurchase transactions described in this
      Paragraph 7, the Exchange Agent shall be acting as agent of the Holders of
      Preferred Securities (in the exchange of Preferred Securities for
      Debentures) and as agent of the Debenture holders (in the exercise of the
      repurchase right with respect to the Debentures), as the case may be,
      directing it to effect such repurchase transactions. The Exchange Agent is
      hereby authorized (i) to exchange Preferred Securities for Debentures held
      by the Trust from time to time in connection with the exercise of the
      repurchase right with respect to such Preferred Securities in accordance
      with this paragraph 7 and the applicable provisions of the Indenture and
      (ii) to exercise the repurchase right with respect to all or a portion of
      the Debentures and thereupon to deliver cash in accordance with the
      provisions of this paragraph 7 and the applicable provisions of the
      Indenture and to deliver to the Trust a new Debenture or Debentures for
      any principal amount of Debentures in respect of which the repurchase
      right shall not have been exercised.

            (f) The Debenture Issuer will comply with the requirements of the
      Exchange Act and any other securities laws and regulations thereunder to
      the extent such laws and regulations are applicable in connection with the
      redemption of the Preferred Securities or the repurchase of the Debentures
      as a result of a Change in Control or a Termination of Trading.

      8. Voting Rights-Preferred Securities.

            (a) Except as provided under paragraphs 8(b), 9(b) and 10 and as
      otherwise required by law and the Declaration, the Holders of the
      Preferred Securities will have no voting rights.

            (b) So long as the Property Trustee holds any Debentures, the
      Trustees may not, without obtaining the prior consent of the holders of a
      majority in liquidation amount of all outstanding Preferred Securities:
      (i) direct the time, method and place of conducting any proceeding for any
      remedy available to the Debenture Trustee, or execute any trust or power
      conferred on the Debenture Trustee with respect to the Debentures; (ii)
      revoke any action previously authorized or approved by a vote of the
      Holders of the Preferred Securities, except by subsequent vote of such
      Holders; (iii) waive any past default that is

                                     A-I-15


      waivable under Section 5.07 of the Indenture; (iv) exercise any right to
      rescind or annul a declaration accelerating the maturity of the principal
      of the Debentures; or (v) consent to any amendment, modification or
      termination of the Indenture or the Debentures, where such consent shall
      be required; provided, where a consent under the Indenture would require
      the consent of Holders of more than a majority of the aggregate principal
      amount of Debentures affected thereby, only the Holders of the percentage
      of that aggregate stated liquidation amount of the Preferred Securities
      which is at least equal to the percentage required under the Indenture may
      direct the Property Trustee to give such consent; provided further, that
      if an event of default under the Indenture has occurred and is continuing,
      then holders of 25% of the aggregate liquidation amount of the Preferred
      Securities may direct the Property Trustee to declare the principal of and
      interest or other required payments on the Debentures due and payable.

      In addition to obtaining the approvals of the Holders of the Preferred
Securities, the Property Trustee shall be under no obligation to take any of the
foregoing actions (except with respect to directing the time, method and place
of conducting a proceeding for a remedy) unless the Property Trustee has
obtained advice of Cadwalader, Wickersham & Taft LLP or an Opinion of Counsel
experienced in such matters to the effect that the Trust will not fail to be
classified as a grantor trust for federal income tax purposes after taking the
action into account, each Holder will be treated as owning an undivided
beneficial interest in the Debentures and the Debentures will be treated as
indebtedness. The Property Trustee shall notify each Holder of Preferred
Securities of any written notice of default it receives with respect to the
Debentures.

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

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

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

                                     A-I-16


      9. Voting Rights-Common Securities.

            (a) Except as provided otherwise under paragraphs 9(b), 9(c) and 10
      or as otherwise required by law and the Declaration, the Holders of the
      Common Securities will have no voting rights.

            (b) Subject to the conditions set forth in Section 5.7 of the
      Declaration, unless an Event of Default shall have occurred and be
      continuing, any Trustee may be appointed or removed without cause at any
      time by vote of the Holders of a Majority in liquidation amount of the
      Common Securities voting as a class at a meeting of Holders of the Common
      Securities. If an Event of Default has occurred and is continuing, the
      Property Trustee and the Delaware Trustee may be removed only by the
      Holders of a Majority in liquidation amount of the Preferred Securities
      voting as a class. In no event will the holders of the Preferred
      Securities have the right to vote to appoint, remove or replace the
      Administrative Trustees, which voting rights are vested exclusively in the
      Initial Purchaser of Common Securities as the holder of the Common
      Securities. No resignation or removal of a Trustee and no appointment of a
      successor trustee shall be effective until the acceptance of appointment
      by the successor trustee in accordance with the provisions of the
      Declaration.

            (c) Unless an Event of Default shall have occurred and be continuing
      and so long as any Debentures are held by the Property Trustee, the
      Trustees shall not (i) direct the time, method and place of conducting any
      proceeding for any remedy available to the Debenture Trustee or executing
      any trust or power conferred on such Debenture Trustee with respect to the
      Debentures, (ii) waive any past default that is waivable under Section
      5.07 of the Indenture, (iii) exercise any right to rescind or annul a
      declaration of acceleration of the maturity of the principal of the
      Debentures or (iv) consent to any amendment, modification or termination
      of the Indenture or the Debentures, where such consent shall be required,
      without, in each case, obtaining the prior approval of the Holders of a
      Majority in liquidation amount of all outstanding Common Securities;
      provided, however, that where a consent under the Indenture would require
      the consent of holders of more than a majority of the aggregate principal
      amount of Debentures affected thereby, only the holders of the percentage
      of that 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 give such consent. The Trustees shall not
      revoke any action previously authorized or approved by a vote of the
      Holders of the Common Securities except by subsequent vote of such
      Holders. The Property Trustee shall notify each Holder of Common
      Securities of any written notice of default it receives with respect to
      the Debentures. In addition to obtaining the foregoing approvals of such
      Holders of the Common Securities prior to taking any of the foregoing
      actions (except with respect to directing the time, method and place of
      conducting a proceeding for a remedy), the Property Trustee shall obtain,
      at the expense of the Initial Purchaser of Common Securities, advice of
      Cadwalader, Wickersham & Taft LLP or an opinion of counsel experienced in
      such matters to the effect that the Trust will continue to be classified
      as a grantor trust for United States federal income tax purposes on
      account of such action, each holder will be treated as owning an undivided
      beneficial interest in the Debentures and the Debentures will be treated
      as indebtedness.

                                     A-I-17


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

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

      10. Pro Rata.

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

      11. Ranking.

      The Trust will pay all Distributions, any redemption price, and any
Liquidation Distribution to Holders of the Preferred Securities and Common
Securities Pro Rata based on the liquidation amount of the Preferred Securities
and Common Securities held. However, if on any Distribution Date or redemption
date, or at the time of a Liquidation Distribution, the Debenture Issuer is in
default under the Indenture, then the Trust will only pay any Distribution,
redemption price, or Liquidation Distribution on the Common Securities after
making payment in full and in cash of all accumulated and unpaid distributions
to Holders of the outstanding Preferred Securities for all distribution periods
terminating on or prior thereto, and in the case of payment of any redemption
price or a Liquidation Distribution, the full amount of the applicable
redemption price or Liquidation Distribution to holders of the outstanding
Preferred Securities then called for redemption or liquidation.

      In the case of any Event of Default, the holder of all of the Common
Securities, will be deemed to have waived any right to act with respect to the
Event of Default until the effect of the Event of Default has been cured or
waived. Until any Event of Default has been cured or waived,

                                     A-I-18


the Property Trustee will act solely on behalf of the Holders of the Preferred
Securities and not on behalf of the Holder of the Common Securities, and only
the holders of the Preferred Securities will have the right to direct the
Property Trustee to act on their behalf.

      12. Acceptance of Securities Guarantee and Indenture.

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

      13. Other Rights of Holders of Preferred Securities.

      If an Event of Default under the Indenture has occurred and is continuing,
then Holders of 25% of the aggregate liquidation amount of the Preferred
Securities may direct the Property Trustee to declare the principal of and
interest or other required payments on the Debentures due and payable.

      If the Property Trustee shall have failed to take a Legal Action under
Section 3.8(e) of the Declaration, after any Holder of Preferred Securities
shall have made a written request to the Property Trustee and not withdrawn such
request to enforce such rights, such Holder of the Preferred Securities may, to
the fullest extent permitted by law, take such Legal Action to enforce the
rights of the Property Trustee under the Debentures; provided, however, that if
an Event of Default has occurred and is continuing, then a Holder of Preferred
Securities may directly institute a proceeding for enforcement of payment to
such Holder of the principal of or Interest on the Debentures having a principal
amount equal to the aggregate liquidation amount of the Preferred Securities of
such Holder (a "Direct Action") on or after the respective due date specified in
the Debentures. Upon the occurrence of an Event of Default, the rights of the
Holders of the Common Securities will be subordinated to the rights of such
Holder of Preferred Securities to the extent of any payment made by the
Debenture Issuer to such Holder of Preferred Securities. Except as provided in
the preceding sentences, the Holders of Preferred Securities will not be able to
exercise directly any other remedy available to the Holders of the Debentures.

      14. No Preemptive Rights.

      The issuance of Preferred Securities and the issuance of Common Securities
are not subject to preemptive or other similar rights. The Holders shall have no
preemptive rights to subscribe for any additional securities.

      15. Agreed Tax Treatment.

      The Trust and, by its acceptance or acquisition of a Security or a
beneficial interest therein, the Holder of, and any Person that acquires a
direct or indirect beneficial interest in, such Security, intend and agree to
treat this Security as indebtedness of the Debenture Issuer for United States
federal, state and local tax purposes, to treat the Trust as a grantor trust for
United States federal, state and local tax purposes, and to treat the Securities
(including but not limited to all payments and proceeds with respect to the
Securities) as undivided beneficial ownership interests in the Securities (and
payments and proceeds therefrom, respectively) for United States federal, state
and local tax purposes, unless otherwise required by law.

                                     A-I-19


      16. Miscellaneous.

      These terms constitute a part of the Declaration.

      The Initial Purchaser of Common Securities will provide a copy of the
Declaration, the Securities Guarantee and/or the Indenture (including any
supplemental indenture) to a Holder without charge upon written request to the
Initial Purchaser of Common Securities at its principal place of business.

rate per annum of 9.75% (the "Coupon Rate") of the liquidation amount of
$1,000.00 per Preferred Security, (ii) at the Coupon Rate on any overdue
Distribution payment (to the extent permitted by applicable law) and (iii) for
any period of time during which any Distribution payment is overdue, at the
Coupon Rate plus 2.00%, in every case, compounded quarterly, and each such rate
being the equivalent rate of interest payable on the Debentures to be held by
the Property Trustee. A Distribution is payable only to the extent that payments
are made in respect of the Debentures held by the Property Trustee and to the
extent the Property Trustee has funds on hand legally available therefor.

      Distributions on the Common Securities will be cumulative, will accrue
from the date of original issuance of the Common Securities and will be payable
quarterly in arrears, on January 1, April 1, July 1 and October 1 of each year,
commencing on October 1, 2007, except as otherwise described below.
Distributions will be computed on the basis of a 360-day year consisting of
twelve 30-day months.

      Subject to the conditions set forth in the Declaration and the Indenture,
the Property Trustee may, at the direction of the Initial Purchaser of Common
Securities, at any time liquidate the Trust and cause the Debentures to be
distributed to the holders of the Securities in liquidation of the Trust or,
simultaneous with any redemption of the Debentures, cause a Like Amount of the
Securities to be redeemed by the Trust.

      Under certain circumstances, the right of the holders of the Common
Securities shall be subordinate to the rights of the holders of the Preferred
Securities (as defined in the Declaration), as provided in the Declaration.

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