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
<PAGE>

      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
<PAGE>

      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.

      provided that any such action does not materially adversely affect the
      interests of the Holders of the Preferred Securities or cause the trust to
      be treated as other than 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;

            (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

            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
<PAGE>

      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
<PAGE>

                  (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
<PAGE>

            (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
<PAGE>

                        (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;

<PAGE>

                  (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).

            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

            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

            request, direction, consent, order, bond, debenture, note, other
            evidence of indebtedness or other paper or document, but the
            Property Trustee, in its discretion, may make such further inquiry
            or investigation into such facts or matters as it may see fit;

                  (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
<PAGE>

            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
<PAGE>

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
<PAGE>

                        (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
<PAGE>

                  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
<PAGE>

            (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.

                                    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
<PAGE>

            (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.

                        (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

      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

            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
<PAGE>

            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
<PAGE>

      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
<PAGE>

(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.

                             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
<PAGE>

      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:

<PAGE>

      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
Affiliate.

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
<PAGE>

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
<PAGE>

      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
<PAGE>

      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
<PAGE>

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
<PAGE>

            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
<PAGE>

      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
<PAGE>

      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.

            (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
<PAGE>

            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.

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.

                                    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
<PAGE>

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
<PAGE>

      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.

                  (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
<PAGE>

            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.

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
<PAGE>

      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.

      defective or inconsistent with any other provision, or to make any other
      provisions with respect to matters or questions arising under the
      Declaration, which shall not be inconsistent with

                                       60
<PAGE>

      the other provisions of the Declaration, (iii) to modify, eliminate or add

      the Debenture Issuer for United States federal income tax purposes or (C)
      the Trust will not be an "investment company" under the Investment Company

      Initial Purchaser of Common Securities; provided, however, that such
      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
      outstanding Securities; provided that, if any amendment would adversely
      affect only the holders of the Preferred Securities or the Common

      amendment and such amendment shall not be effective except with the
      approval of not less than a Majority in liquidation amount of such class
      of securities affected thereby.

            (c) Without the consent of each Holder of Securities, the
      Declaration may not be amended to (i) change the amount or timing of any

      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
      Declaration or the terms of the Securities. The Administrative Trustees

      the Holders of at least 25% in liquidation amount of such class of
      Securities. Such direction

                                       61
<PAGE>

      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
<PAGE>

                  (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.

      Each holder of Preferred Securities, by its acceptance or acquisition of a
Security, represents and covenants that:

            (a) Upon accepting or acquiring a Preferred Security, such Holder
      will provide a properly completed and executed IRS Form W-9, W-8BEN,
      W-8ECI, or W-8IMY (with all appropriate attachments), and certifies that
      no amounts are required to be deducted or withheld in respect of United
      States federal income tax in respect of the Preferred Securities purchased
      by such Holder. Such Holder represents and warrants that it will provide a
      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

                                       64
<PAGE>

      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.

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

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
<PAGE>

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
<PAGE>

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
<PAGE>

      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
<PAGE>

      (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
<PAGE>

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
<PAGE>

      (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).

                                     ANNEX I

                                    TERMS OF
                  9.75% CONVERTIBLE TRUST PREFERRED SECURITIES
                   (LIQUIDATION AMOUNT $1,000.00 PER SECURITY)
                                       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
<PAGE>

            (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
<PAGE>

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
<PAGE>

      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
<PAGE>

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
<PAGE>

      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
<PAGE>

            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
<PAGE>

            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
<PAGE>

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
<PAGE>

      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
<PAGE>

      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
<PAGE>

      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
<PAGE>

            (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
<PAGE>

      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
<PAGE>

      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
<PAGE>

      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.

      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
<PAGE>

      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
<PAGE>

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.

      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.

                          [FORM OF REVERSE OF SECURITY]

      Distributions payable on each Preferred 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 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.

                                   SECURITIES

      SECTION 2.01. Forms Generally.

      The Securities and the Debenture Trustee's certificate of authentication
shall be substantially in the form of Exhibit A, the terms of which are
incorporated in and made a part of this Indenture. The Securities may have
notations, legends or endorsements required by law, stock exchange rule,
agreements to which the Corporation is subject or usage. Each Security shall be
dated the date of its authentication. The Securities shall be issued in
denominations of $1,000 and integral multiples thereof.

      SECTION 2.02. Execution and Authentication.

      One Officer shall sign the Securities for the Corporation by manual or
facsimile signature. If an Officer whose signature is on a Security no longer
holds that office at the time the Security is authenticated, the Security shall
nevertheless be valid.

      A Security shall not be valid until authenticated by the manual or
facsimile signature of the Debenture Trustee. The signature of the Debenture
Trustee shall be conclusive evidence that the Security has been authenticated
under this Indenture. The form of Debenture Trustee's certificate of
authentication to be borne by the Securities shall be substantially as set forth
in Exhibit A hereto.

      The Debenture Trustee shall, upon a Corporation Order, authenticate for
original issue up to, and the aggregate principal amount of Securities
outstanding at any time may not exceed, $128,866,000 aggregate principal amount
of the Securities.

      SECTION 2.03. Form and Payment.

      Except as provided in Section 2.04, the Securities shall be issued in
fully registered certificated form without interest coupons. Principal of and
Interest on the Securities issued in certificated form will be payable, the
transfer of such Securities will be registrable and such Securities will be
exchangeable for Securities bearing identical terms and provisions at the office
or agency of the Corporation maintained for such purpose under Section 3.02;
provided, however, that payment of Interest with respect to Securities (other
than a Global Security) may be made at the option of the Corporation (i) by
check mailed to the holder at such address as shall appear in the Security
Register or (ii) by transfer to an account maintained by the Person entitled
thereto, provided that proper transfer instructions have been received in
writing by the relevant record date. Notwithstanding the foregoing, so long as
the holder of any Securities is the Property Trustee, the payment of the
principal of and Interest on such Securities held by the Property Trustee will
be made at such place and to such account as may be designated by the Property
Trustee.

                                      -14-

      SECTION 2.04. Global Security.

      (a) In connection with a Dissolution Event,

            (i) if any Preferred Securities are held in book-entry form, a Like
      Amount of Definitive Securities shall be presented to the Debenture
      Trustee (if an arrangement with the Depositary has been maintained) by the
      Property Trustee in exchange for one or more Global Securities (as may be
      required pursuant to Section 2.06), to be registered in the name of the
      Depositary, or its nominee, and delivered by the Debenture Trustee to the
      Depositary for crediting to the accounts of its participants pursuant to
      the instructions of the Administrative Trustees; the Corporation upon any
      such presentation shall execute one or more Global Securities in such
      aggregate principal amount and deliver the same to the Debenture Trustee
      for authentication and delivery in accordance with this Indenture; and
      payments on the Securities issued as a Global Security will be made to the
      Depositary; and

            (ii) if any Preferred Securities are held in certificated form, the
      related Definitive Securities may be presented to the Debenture Trustee by
      the Property Trustee and any Preferred Security certificate which
      represents Preferred Securities other than Preferred Securities in
      book-entry form ("Non-Book-Entry Preferred Securities") will be deemed to
      represent beneficial interests in Securities presented to the Debenture
      Trustee by the Property Trustee having an aggregate principal amount equal
      to the aggregate liquidation amount of the Non-Book-Entry Preferred
      Securities until such Preferred Security certificates are presented to the
      security registrar for the Securities for transfer or reissuance, at which
      time such Preferred Security certificates will be cancelled and a
      Security, registered in the name of the holder of the Preferred Security
      certificate or the transferee of the holder of such Preferred Security
      certificate, as the case may be, with an aggregate principal amount equal
      to the aggregate liquidation amount of the Preferred Security certificate
      cancelled, will be executed by the Corporation and delivered to the
      Debenture Trustee for authentication and delivery in accordance with this
      Indenture. Upon the issuance of such Securities, Securities with an
      equivalent aggregate principal amount that were presented by the Property
      Trustee to the Debenture Trustee will be cancelled.

      (b) The Global Securities shall represent the aggregate amount of
outstanding Securities from time to time endorsed thereon; provided, that the
aggregate amount of outstanding Securities represented thereby may from time to
time be reduced or increased, as appropriate, to reflect exchanges, conversions
and redemptions. Any endorsement of a Global Security to reflect the amount of
any increase or decrease in the amount of outstanding Securities represented
thereby shall be made by the Debenture Trustee, in accordance with instructions
given by the Corporation as required by this Section 2.04.

      (c) The Global Securities may be transferred, in whole but not in part,
only to the Depositary, another nominee of the Depositary, or to a successor
Depositary selected or approved by the Corporation or to a nominee of such
successor Depositary.

                                      -15-
<PAGE>

      (d) If at any time the Depositary notifies the Corporation that it is
unwilling or unable to continue as Depositary or the Depositary has ceased to be
a clearing agency registered under the Exchange Act, and a successor Depositary
is not appointed by the Corporation within ninety (90) days after the
Corporation receives such notice or becomes aware of such condition, as the case
may be, the Corporation will execute, and the Debenture Trustee, upon receipt of
a Corporation Order, will authenticate and make available for delivery the
Definitive Securities, in authorized denominations, and in an aggregate
principal amount equal to the principal amount of the Global Security, in
exchange for such Global Security. If there is an Event of Default, the
Depositary shall have the right to exchange the Global Securities for Definitive
Securities. In addition, the Corporation may at any time determine that the
Securities shall no longer be represented by a Global Security. In the event of
such an Event of Default or such a determination, the Corporation shall execute,
and subject to Section 2.07, the Debenture Trustee, upon receipt of an Officers'
Certificate evidencing such determination by the Corporation and a Corporation
Order, will authenticate and make available for delivery the Definitive
Securities, in authorized denominations, and in an aggregate principal amount
equal to the principal amount of the Global Security in exchange for such Global
Security. Upon the exchange of the Global Security for such Definitive
Securities, in authorized denominations, the Global Security shall be cancelled
by the Debenture Trustee. Such Definitive Securities issued in exchange for the
Global Security shall be registered in such names and in such authorized
denominations as the Depositary, pursuant to instructions from its direct or
indirect participants or otherwise, shall instruct the Debenture Trustee. The
Debenture Trustee shall deliver such Definitive Securities to the Depositary for
delivery to the Persons in whose names such Definitive Securities are so
registered.

      SECTION 2.05. Interest.

      (a) Each Security will bear interest (i) at the rate of 9.75% per annum
(the "Coupon Rate") from the most recent date to which interest has been paid or
duly provided for or, if no interest has been paid or duly provided for, from
June 28, 2007, until the principal thereof becomes due and payable, (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 payable quarterly in arrears
on January 1, April 1, July 1 and October 1 of each year (each, an "Interest
Payment Date") commencing on October 1, 2007, except as otherwise provided in
Section 2.10, to the Person in whose name such Security or any Predecessor
Security is registered, as of 5:00 p.m., New York City time on the regular
record date for such interest installment, which shall be the fifteenth (15th)
day of the month, whether or not a Business Day, preceding the relevant Interest
Payment Date.

      (b) Interest will be computed on the basis of a 360-day year consisting of
twelve 30-day months. In the event that any Interest Payment Date falls on a day
that is not a Business Day, then payment of Interest payable on such date will
be made on the next succeeding day which 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 succeeding calendar year, then
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.

                                      -16-
<PAGE>

      (c) If at any time the Trust is required to pay any taxes, duties,
assessments or governmental charges of whatever nature, other than withholding
taxes or backup withholding taxes, imposed by the United States, or any other
taxing authority, then the Corporation will be required to pay additional
amounts on the Securities. The additional amounts will be sufficient so that the
net amounts received and retained by the Trust after paying any such taxes,
duties, assessments or other governmental charges will be not less than the
amounts the Trust would have received had no such taxes, duties, assessments or
other governmental charges been imposed. The intention of this clause is that
the Trust will be in the same position it would have been if it did not have to
pay such taxes, duties, assessments or other charges. The amounts payable
pursuant to this paragraph are referred to as "Additional Sums."

      SECTION 2.06. Transfer and Exchange.

      (a) To permit registrations of transfers, the Corporation shall execute
and the Debenture Trustee shall authenticate Definitive Securities and Global
Securities at the request of the security registrar for the Securities. All
Definitive Securities and Global Securities issued upon any registration of
transfer or exchange of Definitive Securities or Global Securities shall be the
valid obligations of the Corporation, evidencing the same debt, and entitled to
the same benefits under this Indenture, as the Definitive Securities or Global
Securities surrendered upon such registration of transfer or exchange.

      No service charge shall be made to a holder for any registration of
transfer or exchange, but the Corporation may require payment of a sum
sufficient to cover any transfer tax or similar governmental charge payable in
connection therewith.

      The Corporation shall not be required to (i) issue, register the transfer
of or exchange 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 Securities for redemption under Article XIV hereof 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, nothing in this Section
2.06 shall affect the Corporation's obligation to comply with Section 17.01
hereof).

      Prior to due presentment for the registration of a transfer of any
Security, the Debenture Trustee, the Corporation and any agent of the Debenture
Trustee or the Corporation may deem and treat the Person in whose name any
Security is registered as the absolute owner of such Security for the purpose of
receiving payment of principal of and Interest on such Securities, and none of
the Debenture Trustee, the Corporation and any agents of the Debenture Trustee
or the Corporation shall be affected by notice to the contrary.

      (b) Every Security that bears or is required under this Section 2.06(b) to
bear the legend set forth in this Section 2.06(b) (together with any Common
Stock issued upon conversion of the Securities and required to bear the legend
set forth in Section 2.06(c), collectively, the "Restricted Securities") or
Section 2.06(c), as the case may be, shall be subject to the restrictions on
transfer set forth in this Section 2.06(b) or Section 2.06(c), as the case may
be, (including those set forth in the legends set forth below) unless such
restrictions on transfer

                                      -17-
<PAGE>

shall be waived by written consent of the Corporation. Such legends regarding
restrictions on transfer shall not be removed from any Security unless there is
delivered to the Corporation satisfactory evidence, which may include an Opinion
of Counsel, as may be reasonably required to ensure that any future transfers
thereof may be made without restriction under or violation of the provisions of
the Securities Act and other applicable law. Upon provision of such satisfactory
evidence, the Corporation shall execute and deliver to the Debenture Trustee,
and the Debenture Trustee shall deliver, upon receipt of an order from the
Corporation directing it to do so, a Security that does not bear the legend. The
Holder of each such Restricted Security, by such Holder's acceptance thereof,
agrees to be bound by all such restrictions on transfer. As used in Sections
2.06(b) and 2.06(c), the term "transfer" encompasses any sale, pledge, transfer
or other disposition whatsoever of any Restricted Security.

      Until the expiration of the holding period applicable to sales thereof
under Rule 144(k) under the Securities Act (or any successor provision) and
provided that the holder has not been an Affiliate of the Corporation at any
time during the three-month period preceding such date, any certificate
evidencing such Security and all Securities issued in exchange therefor or
substitution thereof (other than Common Stock, if any, issued upon conversion
thereof, which shall bear the legend set forth in Section 2.06(c), if
applicable) shall bear a legend in substantially the following form, unless such
Security has been sold pursuant to a registration statement that has been
declared effective under the Securities Act (and which continues to be effective
at the time of such transfer), or unless otherwise agreed by the Corporation in
writing, with written notice thereof to the Trustee:

at the time of such transfer) or such Common Stock has been issued upon

      (f) The Securities shall be subject to the provisions of Article XVI.

      (g) The Debenture Trustee shall have no obligation or duty to monitor,
determine or inquire as to compliance with any restrictions on transfer imposed
under this Indenture or under applicable law with respect to any transfer of any
interest in any Security (including any transfers between or among Depositary
participants or beneficial owners of interests in any Global 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 Indenture, and to examine the same to determine
substantial compliance as to form with the

                                      -22-
<PAGE>

express requirements hereof. The Debenture Trustee shall have no responsibility
for the actions or omissions of the Depositary, or the accuracy of the books and
records of the Depositary.

      SECTION 2.07. Replacement Securities.

      If any mutilated Security is surrendered to the Debenture Trustee, or the
Corporation and the Debenture Trustee receive evidence to their satisfaction of
the destruction, loss or theft of any Security, the Corporation shall issue and
the Debenture Trustee shall authenticate a replacement Security if the Debenture
Trustee's and the Corporation's requirements, as the case may be, for
replacements of Securities are met. An indemnity bond must be supplied by the
holder that is sufficient in the judgment of the Debenture Trustee and the
Corporation to protect the Corporation, the Debenture Trustee, any agent thereof
or any authenticating agent from any loss that any of them may suffer if a
Security is replaced. The Corporation or the Debenture Trustee may charge for
its expenses in replacing a Security.

      No service charge shall be made to a holder for any registration of
transfer or exchange, but the Corporation may require payment of a sum
sufficient to cover any transfer tax or similar governmental charge payable in
connection therewith.

      Every replacement Security is an obligation of the Corporation and shall
be entitled to all of the benefits of this Indenture equally and proportionately
with all other Securities duly issued hereunder.

      SECTION 2.08. Temporary Securities.

      Pending the preparation of Definitive Securities, the Corporation may
execute, and upon receipt of a Corporation Order the Debenture Trustee shall
authenticate and make available for delivery, temporary Securities that are
printed, lithographed, typewritten, mimeographed or otherwise reproduced, in any
authorized denomination, substantially of the tenor of the Definitive Securities
in lieu of which they are issued and with such appropriate insertions,
omissions, substitutions and other variations as the officers executing such
Securities may determine, as conclusively evidenced by their execution of such
Securities.

      If temporary Securities are issued, the Corporation shall cause Definitive
Securities to be prepared without unreasonable delay. The Definitive Securities
shall be printed, lithographed or engraved, or provided by any combination
thereof, or in any other manner permitted by the rules and regulations of any
applicable securities exchange, all as determined by the officers executing such
Definitive Securities. After the preparation of Definitive Securities, the
temporary Securities shall be exchangeable for Definitive Securities upon
surrender of the temporary Securities at the office or agency maintained by the
Corporation for such purpose pursuant to Section 3.02 hereof, without charge to
the Holder. Upon surrender for cancellation of any one or more temporary
Securities, the Corporation shall execute, and the Debenture Trustee, upon
receipt of a Corporation Order, shall authenticate and make available for
delivery, in exchange therefor the same aggregate principal amount of Definitive
Securities of authorized denominations. Until so exchanged, the temporary
Securities shall in all respects be entitled to the same benefits under this
Indenture as Definitive Securities.

                                      -23-
<PAGE>

      SECTION 2.09. Cancellation.

      The Corporation at any time may deliver Securities to the Debenture
Trustee for cancellation. The Debenture Trustee and no one else shall cancel all
Securities surrendered for registration of transfer, exchange, payment,
replacement, conversion or cancellation and shall retain or destroy cancelled
Securities in accordance with its normal practices (subject to the record
retention requirement of the Exchange Act) unless the Corporation directs them
to be returned to it. The Corporation may not issue new Securities to replace
Securities that have been redeemed, converted or paid (except to evidence any
portion that has not been redeemed, converted or paid) or that have been
delivered to the Debenture Trustee for cancellation.

      SECTION 2.10. Defaulted Interest.

      Any Interest on any Security that is payable, but is not punctually paid
or duly provided for, on any Interest Payment Date (herein called "Defaulted
Interest"), shall forthwith cease to be payable to the holder on the relevant
regular record date by virtue of having been such holder; and such Defaulted
Interest shall be paid by the Corporation, at its election, as provided in
clause (a) or clause (b) below:

      (a) The Corporation may make payment of any Defaulted Interest on
Securities to the Persons in whose names such Securities (or their respective
Predecessor Securities) are registered at the close of business on a special
record date for the payment of such Defaulted Interest, which shall be fixed in
the following manner: the Corporation shall notify the Debenture Trustee in
writing of the amount of Defaulted Interest proposed to be paid on each such
Security and the date of the proposed payment (which date shall be sufficiently
in advance of such notice to permit the Debenture Trustee time to take the
actions contemplated by this Section 2.10), and at the same time the Corporation
shall deposit with the Debenture Trustee an amount of money equal to the
aggregate amount proposed to be paid in respect of such Defaulted Interest or
shall make arrangements satisfactory to the Debenture Trustee for such deposit
prior to the date of the proposed payment, such money when deposited to be held
in trust for the benefit of the Persons entitled to such Defaulted Interest as
in this clause provided. Thereupon the Debenture Trustee shall fix a special
record date for the payment of such Defaulted Interest which shall not be more
than fifteen (15) nor less than ten (10) days prior to the date of the proposed
payment and not less than ten (10) days after the receipt by the Debenture
Trustee of the notice of the proposed payment. The Debenture Trustee shall
promptly notify the Corporation of such special record date and, in the name and
at the expense of the Corporation, shall cause notice of the proposed payment of
such Defaulted Interest and the special record date therefor to be mailed, first
class postage prepaid, to each Securityholder at his or her address as it
appears in the Security Register, not less than ten (10) days prior to such
special record date. Notice of the proposed payment of such Defaulted Interest
and the special record date therefor having been mailed as aforesaid, such
Defaulted Interest shall be paid to the Persons in whose names such Securities
(or their respective Predecessor Securities) are registered on such special
record date and shall be no longer payable pursuant to the following clause (b).

      (b) The Corporation may make payment of any Defaulted Interest on any
Securities in any other lawful manner not inconsistent with the requirements of
any securities exchange on which such Securities may be listed, and upon such
notice as may be required by such exchange,

                                      -24-
<PAGE>

if, after notice given by the Corporation to the Debenture Trustee of the
proposed payment pursuant to this clause, such manner of payment shall be deemed
practicable by the Debenture Trustee.

      SECTION 2.11. CUSIP Numbers.

      The Corporation in issuing the Securities may use "CUSIP" numbers (if then
generally in use), and, if so, the Debenture Trustee shall use "CUSIP" numbers
in notices of redemption or conversion as a convenience to Securityholders;
provided that any such notice may state that no representation is made as to the
correctness of such numbers either as printed on the Securities or as contained
in any notice of a redemption or conversion and that reliance may be placed only
on the other identification numbers printed on the Securities, and any such
redemption or conversion shall not be affected by any defect in or omission of
such numbers. The Corporation will promptly notify the Debenture Trustee of any
change in the CUSIP numbers.

      SECTION 2.12. Tax Treatment.

      Each Security issued hereunder shall provide that the Company 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 such Security as indebtedness of
the Company 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 Preferred Securities (including but not limited to
all payments and proceeds with respect to the Preferred 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. The provisions of this Indenture
shall be interpreted to further this intention and agreement of the parties.

                                  ARTICLE III
                     PARTICULAR COVENANTS OF THE CORPORATION

      SECTION 3.01. Payment of Principal and Interest.

      The Corporation covenants and agrees for the benefit of the holders of the
Securities that it will duly and punctually pay or cause to be paid the
principal of and Interest on the Securities at the place, at the respective
times and in the manner provided on the Securities and herein. Each installment
of Interest on the Securities may be paid at the Corporation's option (i) by
check mailed to the holder at such address as shall appear in the Security
Register or (ii) by transfer to an account maintained by the Person entitled
thereto, provided that proper transfer instructions have been received in
writing by the relevant record date, provided, however, that interest on Global
Securities shall be paid in accordance with the procedures of the Depositary.

      SECTION 3.02. Offices for Notices and Payments, Etc.

      So long as any of the Securities remain outstanding, the Corporation will
maintain an office or agency where the Securities may be presented for payment,
an office or agency where the Securities may be presented for registration of
transfer and for exchange as in this Indenture

                                      -25-
<PAGE>

provided and an office or agency where notices and demands to or upon the
Corporation in respect of the Securities or of this Indenture may be served. The
Corporation will give to the Debenture Trustee written notice of the location of
any such office or agency and of any change of location thereof. Until otherwise
designated from time to time by the Corporation in a notice to the Debenture
Trustee, any such office or agency for all of the above purposes shall be the
Principal Office of the Debenture Trustee. In case the Corporation shall fail to
maintain any such office or agency, or shall fail to give such notice of the
location or of any change in the location thereof, presentations and demands may
be made and notices may be served at the Principal Office of the Debenture
Trustee.

      In addition to any such office or agency, the Corporation may from time to
time designate one or more offices or agencies where the Securities may be
presented for payment, registration of transfer and for exchange in the manner
provided in this Indenture, and the Corporation may from time to time rescind
such designation, as the Corporation may deem desirable or expedient. The
Corporation will give to the Debenture Trustee prompt written notice of any such
designation or rescission thereof.

      SECTION 3.03. Appointments to Fill Vacancies in Debenture Trustee's
Office.

      The Corporation, whenever necessary to avoid or fill a vacancy in the
office of Debenture Trustee, will appoint, in the manner provided in Section
6.10, a Debenture Trustee, so that there shall at all times be a Debenture
Trustee hereunder.

      SECTION 3.04. Provision as to Paying Agent.

      (a) If the Corporation shall appoint a paying agent other than the
Debenture Trustee with respect to the Securities, it will cause such paying
agent to execute and deliver to the Debenture Trustee an instrument in which
such agent shall agree with the Debenture Trustee, subject to the provision of
this Section 3.04,

            (i) that it will hold all sums held by it as such agent for the
      payment of the principal of or Interest on the Securities (whether such
      sums have been paid to it by the Corporation or by any other obligor on
      the Securities) in trust for the benefit of the holders of the Securities;
      and

            (ii) that it will give the Debenture Trustee notice of any failure
      by the Corporation (or by any other obligor on the Securities) to make any
      payment of the principal of or Interest on the Securities when the same
      shall be due and payable.

      (b) If the Corporation shall act as its own paying agent, it will, on or
before each due date of the principal of or Interest on the Securities, set
aside, segregate and hold in trust for the benefit of the holders of the
Securities a sum sufficient to pay such principal or Interest so becoming due
and will notify the Debenture Trustee of any failure to take such action and of
any failure by the Corporation (or by any other obligor under the Securities) to
make any payment of the principal of or Interest on the Securities when the same
shall become due and payable.

                                      -26-

      (c) Anything in this Section 3.04 to the contrary notwithstanding, the
Corporation may, at any time, for the purpose of obtaining a satisfaction and
discharge with respect to the Securities hereunder, or for any other reason, pay
or cause to be paid to the Debenture Trustee all sums held in trust for such
Securities by the Debenture Trustee or any paying agent hereunder, as required
by this Section 3.04, such sums to be held by the Debenture Trustee upon the
trusts herein contained.

      (d) Anything in this Section 3.04 to the contrary notwithstanding, the
agreement to hold sums in trust as provided in this Section 3.04 is subject to
Sections 11.03 and 11.04.

      SECTION 3.05. Certificate to Debenture Trustee.

      The Corporation will deliver to the Debenture Trustee on or before
one-hundred-twenty (120) days after the end of each fiscal year of the
Corporation, commencing with the first fiscal year ending after the date hereof,
so long as Securities are outstanding hereunder, an Officers' Certificate
substantially in the form of Exhibit B attached hereto, one of the signers of
which shall be the principal executive, principal financial or principal
accounting officer of the Corporation, stating that in the course of the
performance by the signers of their duties as officers of the Corporation they
would normally have knowledge of any Default by the Corporation in the
performance of any covenants contained herein, stating whether or not they have
knowledge of any such Default and, if so, specifying each such Default of which
the signers have knowledge and the nature thereof. For purposes of this Section
3.05, Default shall be determined without regard to any period of grace or
requirement of notice provided for herein.

      The Corporation will deliver to the Debenture Trustee, within ten (10)
Business Days of any Event of Default, an Officers' Certificate specifying with
particularity such Event of Default and further stating what action the
Corporation has taken, is taking or proposes to take with respect thereto. Any
notice required to be given under this Section 3.05 shall be delivered to an
officer of the Debenture Trustee at the Principal Office of the Debenture
Trustee.

      SECTION 3.06. Corporate Existence.

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

      SECTION 3.07. Limitation on Dividends.

      The Corporation will not, and will not permit any of its Subsidiaries to,
(i) declare or pay any dividends or distributions on, or redeem, purchase,
acquire, or make a liquidation payment with respect to, any of the Corporation's
capital stock, (ii) make any payment of principal, interest or premium, if any,
on or repay, repurchase or redeem any debt securities of the Corporation
(including Other Debentures) that rank pari passu with or junior in right of
payment to the Securities or (iii) make any guarantee payments with respect to
any guarantee by the Corporation of the debt securities of any Subsidiary of the
Corporation (including Other

                                      -27-
<PAGE>

Guarantees) if such guarantee ranks pari passu with or junior in right of
payment to the Securities, if at such time (1) an event has occurred that with
the giving of notice or the lapse of time, or both, would constitute an Event of
Default and the Corporation has not taken reasonable steps to cure the event
(provided, however, in the event of a Event of Default under Section 5.01(d),
the Corporation shall be entitled to declare and pay dividends on its Common
Stock, but only to the extent necessary to preserve the Corporation's ability to
qualify for taxation as a real estate investment trust under Sections 856
through 860 of the Code (not taking into account consent dividends pursuant to
Section 565 of the Code) or (2) the Corporation shall be in default with respect
to any of its obligations under the Trust Securities Guarantee. The restrictions
set forth in the preceding sentence shall not, however, apply to any of the
following: (a) a payment of dividends or distributions in shares of, or options,
warrants or rights to subscribe for or purchase shares of Common Stock, (b) any
declaration of a dividend in connection with the implementation of, a
shareholder's rights plan, or the issuance of stock under any such plan in the
future, or the redemption or repurchase of any such rights pursuant thereto, (c)
payments under the Trust Securities Guarantee, (d) a reclassification of the
Corporation's capital stock or the exchange or conversion of one class or series
of the Corporation's capital stock for another class or series of the
Corporation's capital stock, (e) the purchase of fractional interests in shares
of the Corporation's capital stock pursuant to the conversion or exchange
provisions of such capital stock or the security being converted or exchanged
and (f) repurchases, redemptions or other acquisitions of shares of capital
stock of the Corporation in connection with any employment contract, benefit
plan or other similar arrangement with or for the benefit of any one or more
employees, officers, directors or consultants, in connection with a dividend
reinvestment or stockholder stock purchase plan or in connection with the
issuance of capital stock of the Corporation (or securities convertible into or
exercisable for such capital stock) as consideration in an acquisition
transaction entered into prior to the applicable Event of Default.

      SECTION 3.08. Covenants as to AHM Capital Trust I.

      In the event Securities are issued to the Trust or a trustee of such trust
in connection with the issuance of Trust Securities by the Trust, for so long as
such Trust Securities remain outstanding, the Corporation: (a) will maintain
100% direct or indirect ownership of the Common Securities of the Trust;
provided, however, that any successor of the Corporation, permitted pursuant to
Article X, may succeed to the Corporation's ownership of such Common Securities,
(b) will use commercially reasonable efforts to cause the Trust to remain a
statutory trust, except in connection with a distribution of Securities to the
holders of Trust Securities in liquidation of the Trust; (c) will not
voluntarily terminate, wind-up or liquidate the Trust, except in connection with
(i) a distribution of the Securities to the holders of the Preferred Securities
in liquidation of the Trust, (ii) the redemption of all of the Preferred
Securities and Common Securities issued by the Trust, (iii) in connection with
mergers, consolidations or amalgamations, in each case as permitted by the
Declaration; (d) will use its reasonable efforts, consistent with the terms and
provisions of the 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; and (e) will use its reasonable efforts to
ensure that the Trust will not be an "investment company" for purposes of the
Investment Company Act.

      withholding taxes, and all liabilities, costs and expenses with respect to
      such taxes of the Trust; and

            (v) pay all other fees, expenses, debts and obligations (other than
      in respect of the Trust Securities) related to the Trust.

      (b) The Corporation acknowledges that any holder of Preferred Securities
may enforce the obligations of the Corporation created under this Section 3.09
pursuant to a Direct Action by such holder against the Corporation and the
Corporation hereby waives any right or remedy that it has or may have to require
that a holder of the Preferred Securities take action against the Trust or any
other person before proceeding against the Corporation and the Corporation
hereby agrees to execute such additional agreements as may be necessary to give
full effect to the agreement described in this sentence.

Debenture Trustee, unless otherwise stated, the Corporation shall pay to the
Debenture Trustee all amounts accrued and owing to the Debenture Trustee to the
date of such termination, removal or resignation. Upon termination of the
Declaration or the removal or resignation of the Delaware Trustee or the
Property Trustee, as the case may be, pursuant to Section 3.06 or 5.07 of the
Declaration, the Corporation shall pay to the Delaware Trustee or the Property
Trustee, as the

                                      -29-

                    SECURITYHOLDERS' LISTS AND REPORTS BY THE
                      CORPORATION AND THE DEBENTURE TRUSTEE

      SECTION 4.01. Securityholders' Lists.

      The Corporation covenants and agrees that it will furnish or cause to be
furnished to the Debenture Trustee:

      (a) on each regular record date for the Securities, a list, in such form
as the Debenture Trustee may reasonably require, of the names and addresses of
the Securityholders as of such record date; and

      (b) at such other times as the Debenture Trustee may request in writing,
within thirty (30) days after the receipt by the Corporation, of any such
request, a list of similar form and content as of a date not more than fifteen
(15) days prior to the time such list is furnished, except that, no such lists
need be furnished so long as the Debenture Trustee is in possession thereof by
reason of its acting as security registrar for the Securities.

      SECTION 4.02. Preservation and Disclosure of Lists.

      (a) The Debenture Trustee shall preserve, in as current a form as is
reasonably practicable, all information as to the names and addresses of the

      (b) The rights of Holders to communicate with other Holders with respect

Corporation nor the Debenture Trustee nor any paying agent shall be held
accountable by reason of the disclosure of any such information as to the names
and addresses of the holders of Securities in accordance with the provisions of
Section 4.02(b), regardless of the source from which such information was
derived, and that the Debenture Trustee shall not be held accountable by reason
of mailing any material pursuant to a request made under Section 4.02(b).

      SECTION 4.03. Reports by the Corporation.

      (a) The Corporation covenants and agrees to file with the Commission all
annual reports and information, documents and other reports which the
Corporation may be required to file with the Commission pursuant to Section 13
or 15(d) of the Exchange Act within the time periods mandated thereby and by the
rules and regulations of the Commission promulgated

                                      -30-
<PAGE>

thereunder and to file the same with the Debenture Trustee, within fifteen (15)
days after the date on which it shall file any such report or information with
the Commission the Corporation is required to file the same with the Commission,
copies of the annual reports and of the information, documents and other reports
(or copies of such portions of any of the foregoing as said Commission may from
time to time by rules and regulations prescribe) which the Corporation may be
required to file with the Commission pursuant to Section 13 or Section 15(d) of
the Exchange Act; or, if the Corporation is not required to file information,
documents or reports pursuant to either of such sections, then to provide to the
Debenture Trustee, such of the supplementary and periodic information, documents
and reports which would have been required pursuant to Section 13 of the
Exchange Act in respect of a security listed and registered on a national
securities exchange as may be prescribed from time to time in such rules and
regulations.

      If the Corporation intends to file its annual and quarterly information
with the Commission in electronic form pursuant to Regulation S-T of the
Commission using the Commission's Electronic Data Gathering, Analysis and
Retrieval ("EDGAR" system), the Corporation shall notify the Debenture Trustee
in the manner prescribed herein of each such annual and quarterly filing. The
Debenture Trustee is hereby authorized and directed to access the EDGAR system
for purposes of retrieving the information so filed. The Debenture Trustee shall
have no duty to search for or obtain any electronic or other filings that the
Corporation makes with the Commission, regardless of whether such filings are
periodic, supplemental or otherwise. Delivery of reports, information and
documents to the Debenture Trustee pursuant to this Section 4.03 shall be solely
for purposes of compliance with this Section 4.03 and, if applicable, with
Section 314(a) of the Trust Indenture Act, but shall not relieve the Corporation
or the Guarantor of the requirement to deliver the information, documents and
reports referred to in Section 4.03(b). The Debenture Trustee's receipt of such
reports, information and documents shall not constitute notice to it of the
content thereof or any matter determinable from the contents thereof, including
the Corporation's compliance with any of its covenants hereunder, as to which
the Debenture Trustee is entitled to rely exclusively upon Officers'
Certificates.

      (b) The Corporation covenants and agrees to file with the Debenture
Trustee and the Commission, in accordance with the rules and regulations
prescribed from time to time by said Commission, such additional information,
documents and reports with respect to compliance by the Corporation with the
conditions and covenants provided for in this Indenture as may be required from
time to time by such rules and regulations.

      (c) The Corporation covenants and agrees to transmit by mail to all
holders of Securities, as the names and addresses of such holders appear upon
the Security Register, within thirty (30) days after the filing thereof with the
Debenture Trustee, such summaries of any information, documents and reports
required to be filed by the Corporation pursuant to Sections 4.03(a) and 4.03(b)
as may be required by rules and regulations prescribed from time to time by the
Commission.

      (d) Delivery of such reports, information and documents to the Debenture
Trustee is for informational purposes only and the Debenture Trustee's receipt
of such shall not constitute constructive notice of any information contained
therein or determinable from information

                                      -31-
<PAGE>

contained therein, including the Corporation's compliance with any of its
covenants hereunder (as to which the Debenture Trustee is entitled to rely
exclusively on Officers' Certificates).

      SECTION 4.04. Reports by the Debenture Trustee.

      (a) The Debenture Trustee shall transmit to Securityholders such reports
concerning the Debenture Trustee and its actions under this Indenture as may be
required pursuant to the Trust Indenture Act at the times and in the manner
provided pursuant thereto. If required by Section 313(a) of the Trust Indenture
Act, the Debenture Trustee shall, within sixty (60) days after January 1 of each
year following the date of this Indenture, commencing January 1, 2008, deliver
to Securityholders a brief report, which complies with the provisions of such
Section 313(a).

      (b) A copy of each such report shall, at the time of such transmission to
Securityholders, be filed by the Debenture Trustee with each stock exchange, if
any, upon which the Securities are listed, with the Commission and with the
Corporation. The Corporation will promptly notify the Debenture Trustee when the
Securities are listed on any stock exchange.

                                   ARTICLE V
              REMEDIES OF THE DEBENTURE TRUSTEE AND SECURITYHOLDERS
                               ON EVENT OF DEFAULT

      SECTION 5.01. Events of Default.

      One or more of the following events of default shall constitute an Event
of Default hereunder (whatever the reason for such Event of Default and whether
it shall be voluntary or involuntary or be effected by operation of law or
pursuant to any judgment, decree or order of any court or any order, rule or
regulation of any administrative or governmental body):

      (a) default in the payment of any Interest on the Securities, whether or
not such payment is prohibited by the subordination provisions of Article XV, or
any Other Debentures when due, and continuance of such default for a period of
thirty (30) days; or

      (b) default in the payment of any principal of the Securities (whether or
not such payment is prohibited by the subordination provisions of Article XV) or
any Other Debentures when due whether at maturity, upon redemption, by
declaration of acceleration of maturity or otherwise; or

      (c) failure by the Corporation to satisfy its conversion obligations in
accordance with the provisions of Article XVII upon exercise of a holder's
conversion right; or

      (d) default in the performance, or breach, of any covenant of the
Corporation in this Indenture (other than a covenant a default in whose
performance or whose breach is elsewhere in this Section specifically dealt
with), and continuance of such default or breach for a period of thirty (30)
days after there has been given, by registered or certified mail, to the
Corporation by the Debenture Trustee or to the Corporation and the Debenture
Trustee by the holders of at least 25% in aggregate principal amount of the
outstanding Securities a written notice specifying such

                                      -32-
<PAGE>

default or breach and requiring it to be remedied and stating that such notice
is a "Notice of Default" hereunder; or

      (e) default under any instrument or other evidence of indebtedness of the
Corporation or any subsidiary (excluding subsidiaries whose indebtedness is not
guaranteed by the Corporation or otherwise secured by any of the Corporation's
assets), aggregating in excess of $5,000,000 in aggregate principal amount
(including, without limitation, repurchase agreements and reverse repurchase
agreements), resulting in the acceleration of such indebtedness, or due to the
failure to pay principal in an amount exceeding $5,000,000 in the aggregate when
due whether at maturity, upon redemption, by declaration of acceleration of
maturity or otherwise and such indebtedness is not discharged, or such default
in payment or acceleration is not cured or rescinded, prior to the receipt of
written notice of acceleration of the Securities; or

      (f) failure by the Corporation or any Subsidiary to pay final judgments
entered by a court or courts of competent jurisdiction aggregating in excess of
$5,000,000, which judgments are not paid, discharged or stayed for a period of
thirty (30) days; or

      (g) a court having jurisdiction in the premises shall enter a decree or
order for relief in respect of the Corporation or any Significant Subsidiary in
an involuntary case under any applicable bankruptcy, insolvency or other similar
law now or hereafter in effect, or appointing a receiver, liquidator, assignee,
custodian, trustee, sequestrator (or similar official) of the Corporation or any
Significant Subsidiary, as the case may be, or for any substantial part of such
entity's property, or ordering the winding-up or liquidation of such entity's
affairs and such decree or order shall remain unstayed and in effect for a
period of ninety (90) consecutive days; or

      (h) the Corporation or any Significant Subsidiary shall commence a
voluntary case under any applicable bankruptcy, insolvency or other similar law
now or hereafter in effect, shall consent to the entry of an order for relief in
an involuntary case under any such law, or shall consent to the appointment of
or taking possession by a receiver, liquidator, assignee, trustee, custodian,
sequestrator (or other similar official) of the Corporation or any Significant
Subsidiary, as the case may be, or of any substantial part of such entity's
property, or shall make any general assignment for the benefit of creditors, or
shall fail generally to pay its debts as they become due; or

      (i) the voluntary or involuntary dissolution, winding-up or termination of
the Trust, except in connection with (i) the distribution of the Securities to
the holders of the Trust Securities in liquidation of the Trust, (ii) the
redemption or conversion of all outstanding Trust Securities of the Trust and
(iii) mergers, consolidations or amalgamations in accordance with the terms and
conditions set forth in Section 3.15 of the Declaration.

      If an Event of Default with respect to Securities at the time outstanding
occurs and is continuing, other than an Event of Default specified under clause
(g) or (h) of this Section 5.01, then, in each and every such case, either the
Debenture Trustee or the holders of not less than 25% in aggregate principal
amount of the Securities then outstanding may declare the principal amount of
all Securities and all accrued and unpaid Interest thereon to be due and payable
immediately, by a notice in writing to the Corporation (and to the Debenture
Trustee if given by

                                      -33-
<PAGE>

the holders of the outstanding Securities), and upon any such declaration the
same shall become immediately due and payable. If the Debenture Trustee or the
holders of Securities do not make such a declaration, the holders of at least
25% in aggregate liquidation amount of the Preferred Securities will have such
right. If an Event of Default specified under clause (g) or (h) of this Section
5.01 occurs, then, in each and every such case, the entire principal amount of
the Securities and all accrued and unpaid Interest thereon shall ipso facto
become immediately due and payable without further action.

      The foregoing provisions, however, are subject to the condition that if,
at any time after the principal of the Securities shall have been so declared
due and payable, and before any judgment or decree for the payment of the moneys
due shall have been obtained or entered as hereinafter provided, (i) the
Corporation shall pay or shall deposit with the Debenture Trustee a sum
sufficient to pay (A) all matured installments of Interest upon all the
Securities and the principal of any and all Securities that shall have become
due other than by acceleration (with interest upon such principal and, to the
extent that payment of such interest is enforceable under applicable law, on
overdue installments of Interest, at the Coupon Rate to the date of such payment
or deposit) and (B) such amount as shall be sufficient to cover compensation due
to the Debenture Trustee and each predecessor Debenture Trustee, their
respective agents, attorneys and counsel, pursuant to Section 6.06, and (ii) any
and all Events of Default under the Indenture, other than the non-payment of the
principal of the Securities which shall have become due solely by such
declaration of acceleration, shall have been cured, waived or otherwise remedied
as provided herein, then, in every such case, the holders of a majority in
aggregate principal amount of the Securities then outstanding, by written notice
to the Corporation and to the Debenture Trustee, may rescind and annul such
declaration and its consequences, but no such waiver or rescission and annulment
shall extend to or shall affect any subsequent Default or shall impair any right
consequent thereon. If the Holders of the Securities fail to annul such
declaration and waive such Default, the holders of a majority in aggregate
liquidation amount of the Preferred Securities shall have such right.

      In case the Debenture Trustee shall have proceeded to enforce any right
under this Indenture and such proceedings shall have been discontinued or
abandoned because of such rescission or annulment or for any other reason or
shall have been determined adversely to the Debenture Trustee, then and in every
such case the Corporation, the Debenture Trustee and the holders of the
Securities shall be restored respectively to their several positions and rights
hereunder, and all rights, remedies and powers of the Corporation, the Debenture
Trustee and the holders of the Securities shall continue as though no such
proceeding had been taken.

      SECTION 5.02. Payment of Securities on Default; Suit Therefor.

      The Corporation covenants that (a) in case Default shall be made in the
payment of any installment of Interest upon any of the Securities as and when
the same shall become due and payable, and such Default shall have continued for
a period of thirty (30) days, or (b) in case Default shall be made in the
payment of the principal on any of the Securities as and when the same shall
have become due and payable, whether at maturity of the Securities or upon
redemption or by declaration or otherwise, then, upon demand of the Debenture
Trustee, the Corporation will pay to the Debenture Trustee, for the benefit of
the holders of the Securities, the whole amount that then shall have become due
and payable on all such Securities for principal or

                                      -34-
<PAGE>

Interest or both, as the case may be, with interest upon the overdue principal
(to the extent that payment of such interest is enforceable under applicable law
and, if the Securities are held by the Trust or a trustee of such trust, without
duplication of any other amounts paid by the Trust or a trustee in respect
thereof); and, in addition thereto, such further amount as shall be sufficient
to cover the costs and expenses of collection, including reasonable compensation
to the Debenture Trustee, its agents, attorneys and counsel, and any other
amount due to the Debenture Trustee pursuant to Section 6.06.

      In case the Corporation shall fail forthwith to pay such amounts upon such
demand, the Debenture Trustee, in its own name and as trustee of an express
trust, shall be entitled and empowered to institute any actions or proceedings
at law or in equity for the collection of the sums so due and unpaid, and may
prosecute any such action or proceeding to judgment or final decree, and may
enforce any such judgment or final decree against the Corporation or any other
obligor on the Securities and collect in the manner provided by law out of the
property of the Corporation or any other obligor on the Securities, wherever
situated, the moneys adjudged or decreed to be payable.

      In case there shall be pending proceedings for the bankruptcy or for the
reorganization of the Corporation or any other obligor on the Securities under
Title 11, United States Code, or any other applicable law, or in case a receiver
or trustee shall have been appointed for the property of the Corporation or such
other obligor, or in the case of any other similar judicial proceedings relative
to the Corporation or other obligor upon the Securities, or to the creditors or
property of the Corporation or such other obligor, the Debenture Trustee,
irrespective of whether the principal of the Securities shall then be due and
payable as therein expressed or by declaration or otherwise and irrespective of
whether the Debenture Trustee shall have made any demand pursuant to the
provisions of this Section 5.02, shall be entitled and empowered, by
intervention in such proceedings or otherwise, to file and prove a claim or
claims for the whole amount of principal and Interest owing and unpaid in
respect of the Securities and, in case of any judicial proceedings, to file such
proofs of claim and other papers or documents as may be necessary or advisable
in order to have the claims of the Debenture Trustee (including any claim for
amounts due to the Debenture Trustee pursuant to Section 6.06) and of the
Securityholders allowed in such judicial proceedings relative to the Corporation
or any other obligor on the Securities, or to the creditors or property of the
Corporation or such other obligor, unless prohibited by applicable law and
regulations, to vote on behalf of the holders of the Securities in any election
of a trustee or a standby trustee in arrangement, reorganization, liquidation or
other bankruptcy or insolvency proceedings or person performing similar
functions in comparable proceedings, and to collect and receive any moneys or
other property payable or deliverable on any such claims, and to distribute the
same after the deduction of its charges and expenses; and any receiver, assignee
or trustee in bankruptcy or reorganization is hereby authorized by each of the
Securityholders to make such payments to the Debenture Trustee, and, in the
event that the Debenture Trustee shall consent to the making of such payments
directly to the Securityholders, to pay to the Debenture Trustee such amounts as
shall be sufficient to cover reasonable compensation to, and expenses of, the
Debenture Trustee, each predecessor Debenture Trustee and their respective
agents, attorneys and counsel, and all other amounts due to the Debenture
Trustee pursuant to Section 6.06.

                                      -35-
<PAGE>

      Nothing herein contained shall be construed to authorize the Debenture
Trustee to authorize or consent to or accept or adopt on behalf of any
Securityholder any plan of reorganization, arrangement, adjustment or
composition affecting the Securities or the rights of any holder thereof or to
authorize the Debenture Trustee to vote in respect of the claim of any
Securityholder in any such proceeding. The Debenture Trustee shall be entitled
to participate as a member of any official committee of creditors in the matters
as it deems necessary or advisable.

      All rights of action and of asserting claims under this Indenture, or
under any of the Securities, may be enforced by the Debenture Trustee without
the possession of any of the Securities, or the production thereof on any trial
or other proceeding relative thereto, and any such suit or proceeding instituted
by the Debenture Trustee shall be brought in its own name as trustee of an
express trust, and any recovery of judgment shall be for the ratable benefit of
the holders of the Securities.

      In any proceedings brought by the Debenture Trustee (and also any
proceedings involving the interpretation of any provision of this Indenture to
which the Debenture Trustee shall be a party) the Debenture Trustee shall be
held to represent all the holders of the Securities, and it shall not be
necessary to make any holders of the Securities parties to any such proceedings.

      SECTION 5.03. Application of Moneys Collected by Debenture Trustee.

      Any moneys collected by the Debenture Trustee shall be applied in the
following order, at the date or dates fixed by the Debenture Trustee for the
distribution of such moneys, upon presentation of the Securities in respect of
which moneys have been collected, and stamping thereon the payment, if only
partially paid, and upon surrender thereof if fully paid:

      First: To the payment of costs and expenses of collection applicable to
the Securities and all other amounts due to the Debenture Trustee under Section
6.06;

      Second: To the payment of all Senior Indebtedness of the Corporation if
and to the extent required by Article XV;

      Third: To the payment of the amounts then due and unpaid upon Securities
for principal of and Interest on the Securities, in respect of which or for the
benefit of which money has been collected, ratably, without preference of
priority of any kind, according to the amounts due on such Securities for
principal and Interest, respectively; and

      Fourth: To the Corporation.

      SECTION 5.04. Proceedings by Securityholders.

      No holder of any Security shall have any right by virtue of or by availing
of any provision of this Indenture to institute any suit, action or proceeding
in equity or at law upon or under or with respect to this Indenture or for the
appointment of a receiver or trustee, or for any other remedy hereunder, unless
such holder previously shall have given to the Debenture Trustee written notice
of an Event of Default and of the continuance thereof with respect to the
Securities specifying such Event of Default, as hereinbefore provided, and
unless also the holders of not

                                      -36-
<PAGE>

less than 25% in aggregate principal amount of the Securities then outstanding
shall have made written request upon the Debenture Trustee and not withdrawn
such request to institute such action, suit or proceeding in its own name as
Debenture Trustee hereunder and shall have offered to the Debenture Trustee such
indemnity reasonably satisfactory to it as it may require against the costs,
expenses and liabilities to be incurred therein or thereby, and the Debenture
Trustee for sixty (60) days after its receipt of such notice, request and offer
of indemnity shall have failed to institute any such action, suit or proceeding,
it being understood and intended, and being expressly covenanted by the taker
and holder of every Security with every other taker and holder and the Debenture
Trustee, that no one or more holders of Securities shall have any right in any
manner whatever by virtue of or by availing of any provision of this Indenture
to affect, disturb or prejudice the rights of any other holder of Securities, or
to obtain or seek to obtain priority over or preference to any other such
holder, or to enforce any right under this Indenture, except in the manner
herein provided and for the equal, ratable and common benefit of all holders of
Securities.

      Notwithstanding any other provisions in this Indenture, however, the right
of any holder of any Security to receive payment of the principal of and
Interest on such Security, on or after the same shall have become due and
payable, or to institute suit for the enforcement of any such payment, shall not
be impaired or affected without the consent of such holder and by accepting a
Security hereunder it is expressly understood, intended and covenanted by the
taker and holder of every Security with every other such taker and holder and
the Debenture Trustee, that no one or more holders of Securities shall have any
right in any manner whatsoever by virtue or by availing of any provision of this
Indenture to affect, disturb or prejudice the rights of the holders of any other
Securities, or to obtain or seek to obtain priority over or preference to any
other such holder, or to enforce any right under this Indenture, except in the
manner herein provided and for the equal, ratable and common benefit of all
holders of Securities. For the protection and enforcement of the provisions of
this Section, each and every Securityholder and the Debenture Trustee shall be
entitled to such relief as can be given either at law or in equity.

      The Corporation and the Debenture Trustee acknowledge that, pursuant to
the Declaration, the holders of Preferred Securities are entitled, under the
circumstances and subject to the limitations set forth therein, to commence a
Direct Action with respect to any Event of Default under this Indenture and the
Securities.

      SECTION 5.05. Proceedings by Debenture Trustee.

      In case an Event of Default occurs with respect to Securities and is
continuing, the Debenture Trustee may in its discretion proceed to protect and
enforce the rights vested in it by this Indenture by such appropriate judicial
proceedings as the Debenture Trustee shall deem most effectual to protect and
enforce any of such rights, either by suit in equity or by action at law or by
proceeding in bankruptcy or otherwise, whether for the specific enforcement of
any covenant or agreement contained in this Indenture or in aid of the exercise
of any power granted in this Indenture, or to enforce any other legal or
equitable right vested in the Debenture Trustee by this Indenture or by law.

                                      -37-
<PAGE>

      SECTION 5.06. Remedies Cumulative and Continuing.

      All powers and remedies given by this Article V to the Debenture Trustee
or to the Securityholders shall, to the extent permitted by law, be deemed
cumulative and not exclusive of any other powers and remedies available to the
Debenture Trustee or the holders of the Securities, by judicial proceedings or
otherwise, to enforce the performance or observance of the covenants and
agreements contained in this Indenture or otherwise established with respect to
the Securities, and no delay or omission of the Debenture Trustee or of any
holder of any of the Securities to exercise any right or power accruing upon any
Event of Default occurring and continuing as aforesaid shall impair any such
right or power, or shall be construed to be a waiver of any such Default or an
acquiescence therein; and, subject to the provisions of Section 5.04, every
power and remedy given by this Article V or by law to the Debenture Trustee or
to the Securityholders may be exercised from time to time, and as often as shall
be deemed expedient, by the Debenture Trustee or by the Securityholders.

      SECTION 5.07. Direction of Proceedings and Waiver of Defaults by Majority
of Securityholders.

      The holders of a majority in aggregate principal amount of the Securities
at the time outstanding shall have the right to direct the time, method, and
place of conducting any proceeding for any remedy available to the Debenture
Trustee, or exercising any trust or power conferred on the Debenture Trustee;
provided, however, that (subject to the provisions of Section 6.01) the
Debenture Trustee shall have the right to decline to follow any such direction
if the Debenture Trustee shall determine that the action so directed would be
unjustly prejudicial to the holders not taking part in such direction or if the
Debenture Trustee being advised by counsel determines that the action or
proceeding so directed may not lawfully be taken or is in conflict with the
Indenture or if the Debenture Trustee in good faith by a Responsible Officer or
Officers shall determine that the action or proceedings so directed would
involve the Debenture Trustee in personal liability. Prior to any declaration
accelerating the maturity of the Securities, the holders of a majority in
aggregate principal amount of the Securities at the time outstanding may on
behalf of the holders of all of the Securities waive any past Default or Event
of Default and its consequences except a Default or Event of Default (a) in the
payment of principal of or Interest on any of the Securities (unless such
Default has been cured and a sum sufficient to pay all matured installments of
Interest and principal due otherwise than by acceleration has been deposited
with the Debenture Trustee) or (b) in respect of covenants or provisions hereof
which cannot be modified or amended without the consent of the holder of each
Security affected; provided, however, that if the Securities are held by the
Property Trustee, such waiver or modification to such waiver shall not be
effective until the holders of a majority in aggregate liquidation amount of
Trust Securities shall have consented to such waiver or modification to such
waiver; provided further, that where a consent under this Indenture would
require the consent of holders of more than a majority of the aggregate
principal amount of the Securities, such waiver shall not be effective until the
holders of at least the same proportion in the aggregate stated liquidation
amount of Trust Securities shall have consented to such waiver. Upon any such
waiver, the Default covered thereby shall be deemed to be cured for all purposes
of this Indenture and the Corporation, the Debenture Trustee and the holders of
the Securities shall be restored to their former positions and rights hereunder,
respectively; but no such waiver shall extend to any subsequent or other Default
or impair any right consequent thereon.

                                      -38-
<PAGE>

Whenever any Default or Event of Default hereunder shall have been waived as
permitted by this Section 5.07, said Default or Event of Default shall for all
purposes of the Securities and this Indenture be deemed to have been cured and
to be not continuing.

      SECTION 5.08. Notice of Defaults.

      The Debenture Trustee shall, within ninety (90) days after the occurrence
of a Default with respect to the Securities actually known to a Responsible
Officer of the Debenture Trustee, mail to all Securityholders, as the names and
addresses of such holders appear upon the Security Register, notice of all
Defaults known to the Debenture Trustee, unless such Default shall have been
cured before the giving of such notice (the term "Default" for the purpose of
this Section 5.08 being hereby defined to be any of the events specified in
clauses (a), (b), (c), (d), (e), (f), (g), (h) and (i) of Section 5.01, not
including periods of grace, if any, provided for therein, and irrespective of
the giving of written notice specified in clause (d) of Section 5.01); and
provided that, except in the case of Default in the payment of the principal of
or Interest on any of the Securities, the Debenture Trustee shall be protected
in withholding such notice if and so long as the board of directors, the
executive committee, or a trust committee of directors and/or Responsible
Officers of the Debenture Trustee in good faith determines that the withholding
of such notice is in the interests of the Securityholders; and provided further
that in the case of any Default of the character specified in Section 5.01(d),
no such notice to Securityholders shall be given until at least sixty (60) days
after the occurrence thereof, but shall be given within ninety (90) days after
such occurrence.

      SECTION 5.09. Undertaking to Pay Costs.

      All parties to this Indenture agree, and each holder of any Security by
his acceptance thereof shall be deemed to have agreed, that any court may in its
discretion require, in any suit for the enforcement of any right or remedy under
this Indenture, or in any suit against the Debenture Trustee for any action
taken or omitted by it as Debenture Trustee, the filing by any party litigant in
such suit of an undertaking to pay the costs of such suit, and that such court
may in its discretion assess reasonable costs, including reasonable attorneys'
fees and expenses, against any party litigant in such suit, having due regard to
the merits and good faith of the claims or defenses made by such party litigant;
but the provisions of this Section 5.09 shall not apply to any suit instituted
by the Debenture Trustee, to any suit instituted by any Securityholder, or group
of Securityholders or holder of Preferred Securities or group of holders of
Preferred Securities, holding in the aggregate more than 10% in aggregate
principal amount of the Securities or liquidation amount of the Preferred
Securities, as the case may be, outstanding, or to any suit instituted by any
Securityholder for the enforcement of the payment of the principal of or
Interest on any Security against the Corporation on or after the same shall have
become due and payable.

      SECTION 5.10. Acknowledgment of Rights.

      If an Event of Default has occurred and is continuing, the Corporation
acknowledges that a registered holder of Preferred Securities may commence a
Direct Action against the Corporation to compel it to make such payment to such
holder of the principal of or Interest on the Securities having a principal
amount equal to the aggregate liquidation amount of the

                                      -39-
<PAGE>

Preferred Securities of such holder on or after the respective due date
specified in the securities. The Corporation may not amend this Indenture to
remove this right to bring a Direct Action without the prior written consent of
the registered holders of all of the Preferred Securities. Notwithstanding any
payments that the Corporation makes to a holder of Preferred Securities in
connection with a Direct Action, the Corporation shall remain obligated to pay
the principal of and Interest on the Securities, and the Corporation shall be
subrogated to the rights of the holder of the Preferred Securities, and have a
right of set-off, with respect to payments on the Preferred Securities to the
extent that the Corporation makes any payments to a holder of Preferred
Securities in any Direct Action.

      The holders of the Preferred Securities shall not be entitled to exercise
directly any remedies, other than those described in the preceding paragraph,
available to Holders of the Securities, unless an event of default exists under
the Declaration.

                                   ARTICLE VI
                        CONCERNING THE DEBENTURE TRUSTEE

      SECTION 6.01. Duties and Responsibilities of Debenture Trustee.

      With respect to the holders of the Securities issued hereunder, the
Debenture Trustee, prior to the occurrence of an Event of Default and after the
curing or waiving of all Events of Default which may have occurred, undertakes
to perform such duties and only such duties as are specifically set forth in
this Indenture. In case an Event of Default has occurred (which has not been
cured or waived), the Debenture Trustee shall exercise such of the rights and
powers vested in it by this Indenture, 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.

      No provision of this Indenture shall be construed to relieve the Debenture
Trustee from liability for its own negligent action, its own negligent failure
to act or its own willful misconduct, except that

      (a) prior to the occurrence of an Event of Default and after the curing or
waiving of all Events of Default which may have occurred,

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

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

                                      -40-
<PAGE>

      requirements of this Indenture (but need not confirm or investigate the
      accuracy of mathematical calculations or other facts stated therein);

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

      (c) the Debenture 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 Securityholders pursuant to Section 5.07, relating to the time,
method and place of conducting any proceeding for any remedy available to the
Debenture Trustee, or exercising any trust or power conferred upon the Debenture
Trustee, under this Indenture.

      None of the provisions contained in this Indenture shall require the
Debenture 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 reasonably believes that the repayment of
such funds or liability is not reasonably assured to it under the terms of this
Indenture or adequate indemnity against such risk is not reasonably assured to
it.

      Whether or not therein expressly so provided, every provision of this
Indenture relating to the conduct or affecting the liability of or affording
protection to the Debenture Trustee shall be subject to the provisions of this
Section.

      SECTION 6.02. Reliance on Documents, Opinions, Etc.

      Except as otherwise provided in Section 6.01:

      (a) the Debenture Trustee may conclusively rely and shall be protected in
acting or refraining from acting upon any resolution, certificate, statement,
instrument, opinion, report, notice, request, consent, order, bond, note,
debenture or other paper or document believed by it to be genuine and to have
been signed or presented by the proper party or parties;

      (b) any request, direction, order or demand of the Corporation mentioned
herein may be sufficiently evidenced by an Officers' Certificate (unless other
evidence in respect thereof be herein specifically prescribed); and any Board
Resolution may be evidenced to the Debenture Trustee by a copy thereof certified
by the Secretary or an Assistant Secretary of the Corporation;

      (c) the Debenture Trustee may consult with counsel of its selection and
any advice or Opinion of Counsel shall be full and complete authorization and
protection in respect of any action taken or suffered or omitted by it hereunder
in good faith and in accordance with such advice or Opinion of Counsel;

      (d) the Debenture Trustee shall be under no obligation to exercise any of
the rights or powers vested in it by this Indenture at the request, order or
direction of any of the Securityholders, pursuant to the provisions of this
Indenture, unless such Securityholders shall have offered to the Debenture
Trustee security or indemnity reasonably satisfactory to the Debenture Trustee
against the costs, expenses and liabilities which may be incurred therein or
thereby;

                                      -41-
<PAGE>

      (e) the Debenture Trustee shall not be liable for any action taken or
omitted by it in good faith and believed by it to be authorized or within the
discretion or rights or powers conferred upon it by this Indenture; nothing
contained herein shall, however, relieve the Debenture Trustee of the
obligation, upon the occurrence of an Event of Default (that has not been cured
or waived), to exercise such of the rights and powers vested in it by this
Indenture, and to use the same degree of care and skill in their exercise, as a
prudent man would exercise or use under the circumstances in the conduct of his
own affairs;

      (f) the Debenture Trustee shall not be bound to make any investigation
into the facts or matters stated in any resolution, certificate, statement,
instrument, opinion, report, notice, request, consent, order, approval, bond,
debenture, coupon or other paper or document, unless requested in writing to do
so by the holders of a majority in aggregate principal amount of the outstanding
Securities; provided, however, that if the payment within a reasonable time to
the Debenture Trustee of the costs, expenses or liabilities likely to be
incurred by it in the making of such investigation is, in the opinion of the
Debenture Trustee, not reasonably assured to the Debenture Trustee by the
security afforded to it by the terms of this Indenture, the Debenture Trustee
may require indemnity reasonably satisfactory to the Debenture Trustee against
such expense or liability as a condition to so proceeding;

      (g) the Debenture Trustee may execute any of the trusts or powers
hereunder or perform any duties hereunder either directly or by or through
agents (including any Authenticating Agent) or attorneys, and the Debenture
Trustee shall not be responsible for any misconduct or negligence on the part of
any such agent or attorney appointed by it with due care;

      (h) the Debenture Trustee shall not be charged with knowledge of any
Default or Event of Default with respect to the Securities unless (1) such
Default is a Default under Sections 5.01(a) (other than (i) a Default with
respect to the payment of Liquidated Damages or Additional Sums or (ii) a
Default with respect to any Other Debentures) or 5.01(b) of the Indenture, (2) a
Responsible Officer shall have actual knowledge of such Default or Event of
Default or (3) written notice of such Default or Event of Default shall have
been given to the Debenture Trustee by the Corporation or any other obligor on
the Securities or by any holder of the Securities;

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

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

      (k) the Debenture Trustee may request that the Corporation 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
Indenture, 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;

                                      -42-
<PAGE>

      (l) the permissive rights of the Debenture Trustee to do things enumerated
in this Indenture shall not be construed as duties; and

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

      SECTION 6.03. No Responsibility for Recitals, Etc.

      The recitals contained herein and in the Securities (except in the
certificate of authentication of the Debenture Trustee or the Authenticating
Agent) shall be taken as the statements of the Corporation, and the Debenture
Trustee and the Authenticating Agent assume no responsibility for the
correctness of the same. The Debenture Trustee and the Authenticating Agent make
no representations as to the validity or sufficiency of this Indenture or of the
Securities. The Debenture Trustee and the Authenticating Agent shall not be
accountable for the use or application by the Corporation of any Securities or
the proceeds of any Securities authenticated and delivered by the Debenture
Trustee or the Authenticating Agent in conformity with the provisions of this
Indenture.

      SECTION 6.04. Debenture Trustee, Authenticating Agent, Paying Agents,
Transfer Agents or Registrar May Own Securities.

      The Debenture Trustee or any Authenticating Agent or any paying agent or
any transfer agent or any security registrar for the Securities, in its
individual or any other capacity, may become the owner or pledgee of Securities
with the same rights it would have if it were not Debenture Trustee,
Authenticating Agent, paying agent, transfer agent or security registrar for the
Securities.

      SECTION 6.05. Moneys to Be Held in Trust.

      Subject to the provisions of Section 11.04, all moneys received by the
Debenture Trustee or any paying agent shall, until used or applied as herein
provided, be held in trust for the purpose for which they were received, but
need not be segregated from other funds except to the extent required by law.
The Debenture Trustee and any paying agent shall be under no liability for
interest on any money received by it hereunder except as otherwise agreed in
writing with the Corporation. So long as no Event of Default shall have occurred
and be continuing, all interest allowed on any such moneys shall be paid from
time to time upon the written order of the Corporation, signed by the Chairman
of the Board of Directors, the President or a Vice President or the Treasurer or
an Assistant Treasurer of the Corporation.

      SECTION 6.06. Compensation and Expenses of Debenture Trustee.

      The Corporation, as issuer of Securities under this Indenture, covenants
and agrees to pay to the Debenture Trustee from time to time, and the Debenture
Trustee shall be entitled to, such compensation as shall be agreed to in writing
between the Corporation and the Debenture

                                      -43-
<PAGE>

Trustee (which shall not be limited by any provision of law in regard to the
compensation of a trustee of an express trust), and the Corporation will pay or
reimburse the Debenture Trustee upon its request for all reasonable expenses,
disbursements and advances incurred or made by the Debenture Trustee in
accordance with any of the provisions of this Indenture (including the
reasonable compensation and the expenses and disbursements of its counsel and of
all persons not regularly in its employ) except any such expense, disbursement
or advance as may arise from its negligence or bad faith. The Corporation also
covenants to indemnify and defend each of the Debenture Trustee (including in
its individual capacity) and any predecessor Debenture Trustee (and its
officers, agents, directors and employees) for, and to hold it harmless against,
any and all loss, damage, claim, liability or expense including taxes (other
than taxes based on the income of the Debenture Trustee) incurred without
negligence or bad faith on the part of the Debenture Trustee and arising out of
or in connection with the acceptance or administration of this trust, including
advancement of the costs and expenses of defending itself against any claim of
liability in the premises. The obligations of the Corporation under this Section
6.06 to compensate and indemnify the Debenture Trustee and to pay or reimburse
the Debenture Trustee for expenses, disbursements and advances shall constitute
additional indebtedness hereunder. Such additional indebtedness shall be secured
by a lien prior to that of the Securities upon all property and funds held or
collected by the Debenture Trustee as such, except funds held in trust for the
benefit of the holders of particular Securities.

      When the Debenture Trustee incurs expenses or renders services in
connection with an Event of Default specified in Section 5.01(g) or Section
5.01(h), the expenses (including the reasonable charges and expenses of its
counsel) and the compensation for the services are intended to constitute
expenses of administration under any applicable federal or state bankruptcy,
insolvency or other similar law.

      The provisions of this Section shall survive the resignation or removal of
the Debenture Trustee and the termination of this Indenture.

      SECTION 6.07. Officers' Certificate as Evidence.

      Except as otherwise provided in Sections 6.01 and 6.02, whenever in the
administration of the provisions of this Indenture the Debenture Trustee shall
deem it necessary or desirable that a matter be proved or established prior to
taking or omitting any action hereunder, such matter (unless other evidence in
respect thereof is herein specifically prescribed) may, in the absence of
negligence or bad faith on the part of the Debenture Trustee, be deemed to be
conclusively proved and established by an Officers' Certificate delivered to the
Debenture Trustee, and such certificate, in the absence of negligence or bad
faith on the part of the Debenture Trustee, shall be full warrant to the
Debenture Trustee for any action taken or omitted by it under the provisions of
this Indenture upon the faith thereof.

      SECTION 6.08. Conflicting Interest of Debenture Trustee.

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

                                      -44-
<PAGE>

      SECTION 6.09. Eligibility of Debenture Trustee.

      The Debenture Trustee hereunder shall at all times be a Person organized
and doing business under the laws of the United States of America or any state
or territory thereof or the District of Columbia, or a Person permitted to act
as trustee by the Commission authorized under such laws to exercise corporate
trust powers, having a combined capital and surplus of at least 50 million U.S.
dollars ($50,000,000) and subject to supervision or examination by federal,
state, territorial, or District of Columbia authority. If such Person publishes
reports of condition at least annually, pursuant to law or to the requirements
of the aforesaid supervising or examining authority, then for the purposes of
this Section 6.09 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.

      The Corporation may not, nor may any Person directly or indirectly
controlling, controlled by, or under common control with the Corporation, serve
as Debenture Trustee.

      In case at any time the Debenture Trustee shall cease to be eligible in
accordance with the provisions of this Section 6.09, the Debenture Trustee shall
resign immediately in the manner and with the effect specified in Section 6.10.

      SECTION 6.10. Resignation or Removal of Debenture Trustee.

      (a) The Debenture Trustee, or any trustee or trustees hereafter appointed,
may at any time resign by giving written notice of such resignation to the
Corporation and by mailing notice thereof to the holders of the Securities at
their addresses as they shall appear on the Security Register. Upon receiving
such notice of resignation, the Corporation shall promptly appoint a successor
trustee or trustees by written instrument, in duplicate, one copy of which
instrument shall be delivered to the resigning Debenture Trustee and one copy to
the successor trustee. If no successor trustee shall have been so appointed and
have accepted appointment within sixty (60) days after the mailing of such
notice of resignation to the affected Securityholders, the resigning Debenture
Trustee, at the expense of the Corporation, may petition any court of competent
jurisdiction for the appointment of a successor trustee, or any Securityholder
who has been a bona fide holder of a Security for at least six months may,
subject to the provisions of Section 5.09, on behalf of himself and all others
similarly situated, petition any such court for the appointment of a successor
trustee. Such court may thereupon, after such notice, if any, as it may deem
proper and prescribe, appoint a successor trustee.

      (b) In case at any time any of the following shall occur:

            (i) the Debenture Trustee shall fail to comply with the provisions
      of Section 6.08 after written request therefor by the Corporation or by
      any Securityholder who has been a bona fide holder of a Security or
      Securities for at least six months, or

            (ii) the Debenture Trustee shall cease to be eligible in accordance
      with the provisions of Section 6.09 and shall fail to resign after written
      request therefor by the Corporation or by any such Securityholder, or

                                      -45-
<PAGE>

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

then, in any such case, the Corporation may remove the Debenture Trustee and
appoint a successor trustee by written instrument, in duplicate, one copy of
which instrument shall be delivered to the Debenture Trustee so removed and one
copy to the successor trustee, or, subject to the provisions of Section 5.09,
any Securityholder who has been a bona fide holder of a Security for at least
six months may, on behalf of himself and all others similarly situated, petition
any court of competent jurisdiction for the removal of the Debenture Trustee and
the appointment of a successor trustee. Such court may thereupon, after such
notice, if any, as it may deem proper and prescribe, remove the Debenture
Trustee and appoint a successor trustee.

      (c) The holders of a majority in aggregate principal amount of the
Securities at the time outstanding may at any time following an Event of Default
remove the Debenture Trustee and nominate a successor trustee, which shall be
deemed appointed as successor trustee unless within ten (10) days after such
nomination the Corporation objects thereto, or if no successor trustee shall
have been so appointed and shall have accepted appointment within thirty (30)
days after such removal, in which case the Debenture Trustee so removed or any
Securityholder, upon the terms and conditions and otherwise as in Section
6.10(a) provided, may petition any court of competent jurisdiction for an
appointment of a successor trustee.

      (d) Any resignation or removal of the Debenture Trustee and appointment of
a successor trustee pursuant to any of the provisions of this Section 6.10 shall
become effective upon acceptance of appointment by the successor trustee as
provided in Section 6.11.

      (e) Notwithstanding replacement of the Debenture Trustee pursuant to this
Section 6.10, the Corporation's obligations under Section 6.06 shall continue
for the benefit of the retiring Debenture Trustee.

      SECTION 6.11. Acceptance by Successor Debenture Trustee.

      Any successor trustee appointed as provided in Section 6.10 shall execute,
acknowledge and deliver to the Corporation and to its predecessor trustee an
instrument accepting such appointment hereunder, and thereupon the resignation
or removal of the retiring trustee shall become effective and such successor
trustee, without any further act, deed or conveyance, shall become vested with
all the rights, powers, duties and obligations of its predecessor hereunder,
with like effect as if originally named as trustee herein; but, nevertheless, on
the written request of the Corporation or of the successor trustee, the trustee
ceasing to act shall, upon payment of any amounts then due it pursuant to the
provisions of Section 6.06, execute and deliver an instrument transferring to
such successor trustee all the rights and powers of the trustee so ceasing to
act and shall duly assign, transfer and deliver to such successor trustee all
property and money held by such retiring trustee thereunder. Upon request of any
such successor trustee, the Corporation shall execute any and all instruments in
writing for more fully and certainly vesting in and confirming to such successor
trustee all such rights and powers. Any trustee

                                      -46-
<PAGE>

ceasing to act shall, nevertheless, retain a lien upon all property or funds
held or collected by such trustee to secure any amounts then due it pursuant to
the provisions of Section 6.06.

      No successor trustee shall accept appointment as provided in this Section
6.11 unless at the time of such acceptance such successor trustee shall be
qualified under the provisions of Section 6.08 and eligible under the provisions
of Section 6.09.

      Upon acceptance of appointment by a successor trustee as provided in this
Section 6.11, the Corporation shall mail notice of the succession of such
trustee hereunder to the holders of Securities at their addresses as they shall
appear on the Security Register. If the Corporation fails to mail such notice
within ten (10) days after the acceptance of appointment by the successor
trustee, the successor trustee shall cause such notice to be mailed at the
expense of the Corporation.

      SECTION 6.12. Succession by Merger, Etc.

      Any Person into which the Debenture Trustee may be merged or converted or
with which it may be consolidated, or any Person resulting from any merger,
conversion or consolidation to which the Debenture Trustee shall be a party, or
any Person succeeding to all or substantially all of the corporate trust
business of the Debenture Trustee, shall be the successor of the Debenture
Trustee hereunder without the execution or filing of any paper or any further
act on the part of any of the parties hereto.

      In case at the time such successor to the Debenture Trustee shall succeed
to the trusts created by this Indenture any Securities shall have been
authenticated but not delivered, any such successor to the Debenture Trustee may
adopt the certificate of authentication of any predecessor trustee, and deliver
such Securities so authenticated; and in case at that time any of the Securities
shall not have been authenticated, any successor to the Debenture Trustee may
authenticate such Securities either in the name of any predecessor hereunder or
in the name of the successor trustee; and in all such cases such certificates
shall have the full force which the Securities or this Indenture elsewhere
provides that the certificate of the Debenture Trustee shall have; provided,
however, that the right to adopt the certificate of authentication of any
predecessor Debenture Trustee or authenticate Securities in the name of any
predecessor Debenture Trustee shall apply only to its successor or successors by
merger, conversion or consolidation.

      SECTION 6.13. Limitation on Rights of Debenture Trustee as a Creditor.

      The Debenture Trustee shall comply with Section 311(a) of the Trust
Indenture Act, excluding any creditor relationship described in Section 311(b)
of the Trust Indenture Act. A Debenture Trustee who has resigned or been removed
shall be subject to Section 311(a) of the Trust Indenture Act to the extent
included therein.

      SECTION 6.14. Co-trustees and Separate Trustees.

      At any time or times, at the expense of the Corporation and for the
purpose of meeting the legal requirements of any applicable jurisdiction, the
Corporation and the Debenture Trustee shall have power to appoint, and, upon the
written request of the Debenture Trustee or of the holders of at least 25% in
principal amount of the Securities then outstanding, the Corporation

                                      -47-
<PAGE>

shall for such purpose join with the Debenture Trustee in the execution and
delivery of all instruments and agreements necessary or proper to appoint, one
or more Persons approved by the Debenture Trustee, or to act as separate
trustee, jointly with the Debenture Trustee, or to act as separate trustee, in
either case with such powers as may be provided in the instrument of
appointment, and to vest in such Person or Persons, in the capacity aforesaid,
any property, title, right or power deemed necessary or desirable, subject to
the other provisions of this Section. If the Corporation does not join in such
appointment within fifteen (15) days after the receipt by it of a request so to
do, or if an Event of Default shall have occurred and be continuing, the
Debenture Trustee alone shall have power to make such appointment.

      Should any written instrument or instruments from the Corporation be
required by any co-trustee or separate trustee so appointed to more fully
confirm to such co-trustee or separate trustee such property, title, right or
power, any and all such instruments shall, on request, be executed, acknowledged
and delivered by the Corporation.

      Every co-trustee or separate trustee shall, to the extent permitted by
law, but to such extent only, be appointed subject to the following conditions:

      (a) the Securities shall be authenticated and delivered, and all rights,
powers, duties and obligations hereunder in respect of the custody of
securities, cash and other personal property held by, or required to be
deposited or pledged with, the Debenture Trustee hereunder, shall be exercised
solely, by the Debenture Trustee;

      (b) the rights, powers, duties and obligations hereby conferred or imposed
upon the Debenture Trustee in respect of any property covered by such
appointment shall be conferred or imposed upon and exercised or performed either
by the Debenture Trustee or by the Debenture Trustee and such co-trustee or
separate trustee jointly, as shall be provided in the instrument appointing such
co-trustee or separate trustee, except to the extent that under any law of any
jurisdiction in which any particular act is to be performed, the Debenture
Trustee shall be incompetent or unqualified to perform such act, in which event
such rights, powers, duties and obligations shall be exercised and performed by
such co-trustee or separate trustee;

      (c) the Debenture Trustee at any time, by an instrument in writing
executed by it, with the concurrence of the Corporation, may accept the
resignation of or remove any co-trustee or separate trustee appointed under this
Section, and, if an Event of Default shall have occurred and be continuing, the
Debenture Trustee shall have power to accept the resignation of, or remove, any
such co-trustee or separate trustee without the concurrence of the Corporation.
Upon the written request of the Debenture Trustee, the Corporation shall join
with the Debenture Trustee in the execution and delivery of all instruments and
agreements, necessary or proper to effectuate such resignation or removal. A
successor to any co-trustee or separate trustee so resigned or removed may be
appointed in the manner provided in this Section;

      (d) no co-trustee or separate trustee hereunder shall be personally liable
by reason of any act or omission of the Debenture Trustee, or any other such
trustee hereunder; and

      (e) any notice from the holders of Securities delivered to the Debenture
Trustee shall be deemed to have been delivered to each such co-trustee and
separate trustee.

                                      -48-
<PAGE>

      SECTION 6.15. Authenticating Agents.

      There may be one or more Authenticating Agents appointed by the Debenture
Trustee upon the request of the Corporation with power to act on its behalf and
subject to its direction in the authentication and delivery of Securities issued
upon exchange or transfer thereof as fully to all intents and purposes as though
any such Authenticating Agent had been expressly authorized to authenticate and
deliver Securities; provided that the Debenture Trustee shall have no liability
to the Corporation for any acts or omissions of the Authenticating Agent with
respect to the authentication and delivery of Securities. Any such
Authenticating Agent shall at all times be a corporation organized and doing
business under the laws of the United States or of any state or territory
thereof or of the District of Columbia authorized under such laws to act as
Authenticating Agent, having a combined capital and surplus of at least
$50,000,000 and being subject to supervision or examination by federal, state,
territorial or District of Columbia authority. If such corporation publishes
reports of condition at least annually pursuant to law or the requirements of
such authority, then for the purposes of this Section 6.15 the combined capital
and surplus of such corporation shall be deemed to be its combined capital and
surplus as set forth in its most recent report of condition so published. If at
any time an Authenticating Agent shall cease to be eligible in accordance with
the provisions of this Section, it shall resign immediately in the manner and
with the effect herein specified in this Section.

      Any corporation into which any Authenticating Agent may be merged or
converted or with which it may be consolidated, or any corporation resulting
from any merger, consolidation or conversion to which any Authenticating Agent
shall be a party, or any corporation succeeding to the corporate trust business
of any Authenticating Agent, shall be the successor of such Authenticating Agent
hereunder, if such successor corporation is otherwise eligible under this
Section 6.15 without the execution or filing of any paper or any further act on
the part of the parties hereto or such Authenticating Agent.

      Any Authenticating Agent may at any time resign by giving written notice
of resignation to the Debenture Trustee and to the Corporation. The Debenture
Trustee may at any time terminate the agency of any Authenticating Agent by
giving written notice of termination to such Authenticating Agent and to the
Corporation. Upon receiving such a notice of resignation or upon such a
termination, or in case at any time any Authenticating Agent shall cease to be
eligible under this Section 6.15, the Debenture Trustee may, and upon the
request of the Corporation shall, promptly appoint a successor Authenticating
Agent eligible under this Section 6.15, shall give written notice of such
appointment to the Corporation and the Corporation shall mail notice of such
appointment to all Securityholders as the names and addresses of such holders
appear on the Security Register. Any successor Authenticating Agent upon
acceptance of its appointment hereunder shall become vested with all rights,
powers, duties and responsibilities of its predecessor hereunder, with like
effect as if originally named as Authenticating Agent herein.

      The Corporation, as borrower, agrees to pay to any Authenticating Agent
from time to time reasonable compensation for its services. Any Authenticating
Agent shall have no responsibility or liability for any action taken by it as
such in accordance with the directions of the Debenture Trustee.

                                  ARTICLE VII
                         CONCERNING THE SECURITYHOLDERS

      SECTION 7.01. Action by Securityholders. Whenever in this Indenture it is
provided that the holders of a specified percentage in aggregate principal
amount of the Securities may take any action (including the making of any demand
or request, the giving of any notice, consent or waiver or the taking of any
other action), the fact that at the time of taking any such action the holders
of such specified percentage have joined therein may be evidenced (a) by any
instrument or any number of instruments of similar tenor executed by such
Securityholders in person or by agent or proxy appointed in writing, or (b) by
the record of such holders of Securities voting in favor thereof at any meeting
of such Securityholders duly called and held in accordance with the provisions
of Article VIII, or (c) by a combination of such instrument or instruments and
any such record of such a meeting of such Securityholders.

      If the Corporation shall solicit from the Securityholders any request,
demand, authorization, direction, notice, consent, waiver or other action, the
Corporation may, at its option, as evidenced by an Officers' Certificate, fix in
advance a record date for the determination of Securityholders entitled to give
such request, demand, authorization, direction, notice, consent, waiver or other
action, but the Corporation shall have no obligation to do so. If such a record
date is fixed, such request, demand, authorization, direction, notice, consent,
waiver or other action may be given before or after the record date, but only
the Securityholders of record at the close of business on the record date shall
be deemed to be Securityholders for the purposes of determining whether
Securityholders of the requisite proportion of outstanding Securities have
authorized or agreed or consented to such request, demand, authorization,
direction, notice, consent, waiver or other action, and for that purpose the
outstanding Securities shall be computed as of the record date; provided,
however, that no such authorization, agreement or consent by such
Securityholders on the record date shall be deemed effective unless it shall
become effective pursuant to the provisions of this Indenture not later than six
months after the record date.

      SECTION 7.02. Proof of Execution by Securityholders.

      Subject to the provisions of Section 6.01, 6.02 and 8.05, proof of the
execution of any instrument by a Securityholder or his agent or proxy shall be
sufficient if made in accordance with such reasonable rules and regulations as
may be prescribed by the Debenture Trustee or in such manner as shall be
satisfactory to the Debenture Trustee. The ownership of Securities shall be
proved by the Security Register or by a certificate of the security registrar
for the Securities. The Debenture Trustee may require such additional proof of
any matter referred to in this Section 7.02 as it shall deem necessary.

      The record of any Securityholders' meeting shall be proved in the manner
provided in Section 8.06.

                                      -50-

      SECTION 7.03. Who Are Deemed Absolute Owners.

      Prior to due presentment for registration of transfer of any Security, the
Corporation, the Debenture Trustee, any Authenticating Agent, any paying agent,
any transfer agent and any security registrar for the Securities may deem the
person in whose name such Security shall be registered upon the Security
Register to be, and may treat him as, the absolute owner of such Security
(whether or not such Security shall be overdue) for the purpose of receiving
payment of or on account of the principal of and (subject to Section 2.05)
Interest on such Security and for all other purposes; and neither the
Corporation nor the Debenture Trustee nor any Authenticating Agent nor any
paying agent nor any transfer agent nor any security registrar for the
Securities shall be affected by any notice to the contrary. All such payments so
made to any holder for the time being or upon his order shall be valid, and, to
the extent of the sum or sums so paid, effectual to satisfy and discharge the
liability for moneys payable upon any such Security.

      SECTION 7.04. Securities Owned by Corporation Deemed Not Outstanding.

      In determining whether the holders of the requisite aggregate principal
amount of Securities have concurred in any direction, consent or waiver under
this Indenture, Securities which are owned by the Corporation or any other
obligor on the Securities or by any Person directly or indirectly controlling or
controlled by or under direct or indirect common control with the Corporation or
any other obligor on the Securities shall be disregarded and deemed not to be
outstanding for the purpose of any such determination; provided that for the
purposes of determining whether the Debenture Trustee shall be protected in
relying on any such direction, consent or waiver, only Securities which a
Responsible Officer of the Debenture Trustee actually knows are so owned shall
be so disregarded. Securities so owned which have been pledged in good faith may
be regarded as outstanding for the purposes of this Section 7.04 if the pledgee
shall establish to the satisfaction of the Debenture Trustee the pledgee's right
to vote such Securities and that the pledgee is not the Corporation or any such
other obligor or Person directly or indirectly controlling or controlled by or
under direct or indirect common control with the Corporation or any such other
obligor. In the case of a dispute as to such right, any decision by the
Debenture Trustee taken upon the advice of counsel shall be full protection to
the Debenture Trustee.

      SECTION 7.05. Revocation of Consents; Future Holders Bound.

      At any time prior to (but not after) the evidencing to the Debenture
Trustee, as provided in Section 7.01, of the taking of any action by the holders
of the percentage in aggregate principal amount of the Securities specified in
this Indenture in connection with such action, any holder of a Security (or any
Security issued in whole or in part in exchange or substitution therefor),
subject to Section 7.01, the serial number of which is shown by the evidence to
be included in the group of Securities the holders of which have consented to
such action may, by filing written notice with the Debenture Trustee at its
principal office and upon proof of holding as provided in Section 7.02, revoke
such action so far as concerns such Security (or so far as concerns the
principal amount represented by any exchanged or substituted Security). Except
as aforesaid any such action taken by the holder of any Security shall be
conclusive and binding upon such holder and upon all future holders and owners
of such Security, and of any Security

                                      -51-
<PAGE>

issued in exchange or substitution therefor, irrespective of whether or not any
notation in regard thereto is made upon such Security or any Security issued in
exchange or substitution therefor.

                                  ARTICLE VIII

time pursuant to the provisions of this Article VIII for any of the following
purposes:

      (a) to give any notice to the Corporation or to the Debenture Trustee, or
to give any directions to the Debenture Trustee, or to consent to the waiving of
any Default hereunder and its consequences, or to take any other action
authorized to be taken by Securityholders pursuant to any of the provisions of
Article V;

      (b) to remove the Debenture Trustee and nominate a successor trustee

      (c) to consent to the execution of an indenture or indentures supplemental

holders of any specified aggregate principal amount of such Securities under any
other provision of this Indenture or under applicable law.

      SECTION 8.02. Call of Meetings by Debenture Trustee.

      The Debenture Trustee may at any time call a meeting of Securityholders to
take any action specified in Section 8.01, to be held at such time and at such
place in New York, New York, as the Debenture Trustee shall determine. Notice of
every meeting of the Securityholders, setting forth the time and the place of
such meeting and in general terms the action proposed to be taken at such
meeting, shall be mailed to holders of Securities at their addresses as they
shall appear on the Securities Register. Such notice shall be mailed not less
than twenty (20) nor more than sixty (60) days prior to the date fixed for the
meeting.

      SECTION 8.03. Call of Meetings by Corporation or Securityholders.

      In case at any time the Corporation, pursuant to a resolution of the Board
of Directors, or the holders of at least 25% in aggregate principal amount of
the Securities then outstanding, shall have requested the Debenture Trustee to
call a meeting of Securityholders, by written request setting forth in
reasonable detail the action proposed to be taken at the meeting, and the
Debenture Trustee shall not have mailed the notice of such meeting within twenty
(20) days after receipt of such request, then the Corporation or such
Securityholders may determine the time and the place in New York, New York for
such meeting and may call such meeting to take any action authorized in Section
8.01, by mailing notice thereof as provided in Section 8.02.

      SECTION 8.04. Qualifications for Voting.

      To be entitled to vote at any meeting of Securityholders a Person shall
(a) be a holder of one or more Securities or (b) be a Person appointed by an

Persons who shall be entitled to be present or to speak at any meeting of
Securityholders shall be the Persons entitled to vote at such meeting and their

representatives of the Corporation and its counsel.

      SECTION 8.05. Regulations.

      Notwithstanding any other provisions of this Indenture, the Debenture

inspectors of votes, the submission and examination of proxies, certificates and
other evidence of the right to vote, and such other matters concerning the
conduct of the meeting as it shall think fit.

      The Debenture Trustee shall, by an instrument in writing, appoint a
temporary chairman of the meeting, unless the meeting shall have been called by
the Corporation or by Securityholders as provided in Section 8.03, in which case
the Corporation or the Securityholders calling the meeting, as the case may be,
shall in like manner appoint a temporary chairman. A permanent chairman and a
permanent secretary of the meeting shall be elected by majority vote of the

      Subject to the provisions of Section 8.04, at any meeting each holder of

principal amount of Securities held or represented by him; provided, however,
that no vote shall be cast or counted at any meeting in respect of any Security
challenged as not outstanding and ruled by the chairman of the meeting to be not
outstanding. The chairman of the meeting shall have no right to vote other than
by virtue of Securities held by him or instruments in writing as aforesaid duly

meeting of Securityholders duly called pursuant to the provisions of Section
8.02 or 8.03 may be adjourned from time to time by a majority of those present,

      SECTION 8.06. Voting.

      The vote upon any resolution submitted to any meeting of holders of

chairman of the meeting shall appoint two inspectors of votes who shall count
all votes cast at the meeting for or against any resolution and who shall make
and file with the secretary of the meeting their verified written reports in
triplicate of all votes cast at the meeting. A record in duplicate of the
proceedings of each meeting of Securityholders shall be prepared by the
secretary of the meeting and there shall be attached to said record the original
reports of the inspectors of votes on any vote by ballot taken thereat and
affidavits by one or

                                      -53-
<PAGE>

more persons having knowledge of the facts setting forth a copy of the notice of

duplicates shall be delivered to the Corporation and the other to the Debenture
Trustee to be preserved by the Debenture Trustee, the latter to have attached
thereto the ballots voted at the meeting.

      Any record so signed and verified shall be conclusive evidence of the
matters therein stated.

                                   ARTICLE IX
                                   AMENDMENTS

      SECTION 9.01. Without Consent of Securityholders.

      The Corporation, when authorized by a Board Resolution, and the Debenture
Trustee may from time to time and at any time amend the Indenture, without the
consent of the Securityholders, for one or more of the following purposes:

      (a) to evidence the succession of another Person to the Corporation, or
successive successions, and the assumption by the successor Person of the
covenants, agreements and obligations of the Corporation pursuant to Article X;

      (b) to add additional Events of Default or to add to the covenants of the
Corporation such further covenants, restrictions or conditions for the
protection of the Securityholders as the Board of Directors and the Debenture
Trustee shall consider to be for the protection of the Securityholders, and to
make the occurrence, or the occurrence and continuance, of a default in any of
such additional covenants, restrictions or conditions a Default or an Event of
Default permitting the enforcement of all or any of the remedies provided in
this Indenture as herein set forth; provided, however, that in respect of any
such additional covenant, restriction or condition such amendment may provide
for a particular period of grace after default (which period may be shorter or
longer than that allowed in the case of other defaults) or may provide for an
immediate enforcement upon such default or may limit the remedies available to
the Debenture Trustee upon such default;

      (c) to provide for the issuance under this Indenture of Securities in
coupon form (including Securities registrable as to principal only) and to
provide for exchangeability of such Securities with the Securities issued
hereunder in fully registered form and to make all appropriate changes for such
purpose;

      (d) to cure any ambiguity or to correct or supplement any provision
contained herein or in any supplemental indenture which may be defective or
inconsistent with any other provision contained herein or in any supplemental
indenture, or to make such other provisions in regard to matters or questions
arising under this Indenture;

      (e) to evidence and provide for the acceptance of appointment hereunder by
a successor trustee with respect to the Securities;

                                      -54-
<PAGE>

      (f) to make provision for transfer procedures, certification, book-entry
provisions and all other matters required pursuant to Section 2.07 or otherwise
necessary, desirable or appropriate in connection with the issuance of
Securities to holders of Preferred Securities in the event of a distribution of
Securities by the Trust following a Dissolution Event;

      (g) to qualify or maintain qualification of this Indenture under the Trust
Indenture Act; or

      (h) to modify, eliminate or add to any provisions of the Indenture or the
Securities to such extent as shall be necessary to ensure that the Securities
are treated as indebtedness of the Company for United States federal, state and
local tax purposes, the Trust is treated as a grantor trust for United States
federal, state and local tax purposes, and the Preferred Securities (including
but not limited to all payments and proceeds with respect to the Preferred
Securities) are treated as undivided beneficial ownership interests in the
Securities (and payments and proceeds therefrom, respectively) for United States
federal, state and local tax purposes;

      (i) to ensure that the Trust is not required to register as an investment
company under the Investment Company Act; or

      (j) to make any change that does not adversely affect the rights of any
Securityholder in any material respect;

provided that any such amendment does not materially adversely affect the
interests of Securityholders or cause the Trust to be treated other than as a
grantor trust for United States federal income tax purposes.

      The Debenture Trustee is hereby authorized to join with the Corporation in
the execution of any supplemental indenture to effect such amendment, to make
any further appropriate agreements and stipulations which may be therein
contained and to accept the conveyance, transfer and assignment of any property
thereunder, but the Debenture Trustee shall not be obligated to, but may in its
discretion, enter into any such supplemental indenture which affects the
Debenture Trustee's own rights, duties, privileges or immunities under this
Indenture or otherwise.

      Any amendment to the Indenture authorized by the provisions of this
Section 9.01 may be executed by the Corporation and the Debenture Trustee
without the consent of the holders of any of the Securities at the time
outstanding, notwithstanding any of the provisions of Section 9.02.

      SECTION 9.02. With Consent of Securityholders.

      With the consent (evidenced as provided in Section 7.01) of the holders of
a majority in aggregate principal amount of the Securities at the time
outstanding, the Corporation, when authorized by a Board Resolution, and the
Debenture Trustee may from time to time and at any time amend the Indenture for
the purpose of adding any provisions to or changing in any manner or eliminating
any of the provisions of this Indenture or of modifying in any manner the rights
of the holders of the Securities; provided, however, that no such amendment
shall, without the consent of the holders of each Security then outstanding and
affected thereby (i) change the

                                      -55-
<PAGE>

Maturity Date of any Security, or reduce the principal amount of, or any
installment of principal of or Interest on the Securities; (ii) reduce the rate
or extend the time of payment of Interest; (iii) change any of the provisions of
Article XIV relating to redemption; (iv) change the Conversion Rate except as
provided in Section 17.03 and Section 17.04 with respect to adjustment of the
Conversion Rate, or otherwise change the right to convert the Securities in each
case, in a manner that would be adverse to Securityholders; (v) make the
principal of, or Interest payment on, the Securities payable in any coin or
currency other than that provided herein; (vi) change any obligation of the
Corporation to maintain an office or agency in the places and for the purposes
required by the Indenture or change the place of payment where the Securities or
any Interest payment thereon is payable; (vii) impair or affect the right of any
holder of Securities to institute suit for the payment of the Securities as
provided herein; (viii) reduce the percentage of the principal amount of the
Securities required to consent to modify or amend the Indenture or for any
waiver of compliance with provisions of the Indenture as stated herein or for
waiver of Defaults as stated herein; (ix) make any change adverse to a Holder
with respect to the subordination provisions of Article XV; or (x) modify any of
the foregoing provisions; provided, however, that if the Securities are held by
the Trust, no such modification or amendment referred to in clauses (i) through
(x) shall be effective until the holders of not less than a majority of the
aggregate liquidation amount of the Trust Securities shall have consented to
such modification or amendment; and provided further, however, that where a
consent under the Indenture would require the consent of Securityholders of more
than a majority of the principal amount of the Securities, such modification or
amendment shall not be effective until the holders of at least the same
proportion in aggregate stated liquidation amount of the Trust Securities shall
have consented to such modification or amendment.

      Upon the request of the Corporation accompanied by a copy of a resolution
of the Board of Directors certified by its secretary or assistant secretary
authorizing the execution of any supplemental indenture effecting such
amendment, and upon the filing with the Debenture Trustee of evidence of the
consent of Securityholders as aforesaid, the Debenture Trustee shall join with
the Corporation in the execution of such supplemental indenture unless such
supplemental indenture affects the Debenture Trustee's own rights, duties,
privileges or immunities under this Indenture or otherwise, in which case the
Debenture Trustee may in its discretion, but shall not be obligated to, enter
into such supplemental indenture.

      Promptly after the execution by the Corporation and the Debenture Trustee
of any supplemental indenture pursuant to the provisions of this Section, the
Debenture Trustee, at the expense of the Corporation, shall transmit by mail,
first-class postage prepaid, a notice, prepared by the Corporation, setting
forth in general terms the substance of such supplemental indenture, to the
Securityholders as their names and addresses appear upon the Security Register.
Any failure of the Debenture Trustee to mail such notice, or any defect therein,
shall not, however, in any way impair or affect the validity of any such
supplemental indenture.

      It shall not be necessary for the consent of the Securityholders under
this Section 9.02 to approve the particular form of any proposed supplemental
indenture, but it shall be sufficient if such consent shall approve the
substance thereof.

      SECTION 9.03. Compliance with Trust Indenture Act; Effect of Supplemental
Indentures.

      Any supplemental indenture executed pursuant to the provisions of this
Article IX shall comply with the Trust Indenture Act to the extent required by
law. Upon the execution of any supplemental indenture pursuant to the provisions
of this Article IX, this Indenture shall be and be deemed to be modified and
amended in accordance therewith and the respective rights, limitations of
rights, obligations, duties, privileges and immunities under this Indenture of
the Debenture Trustee, the Corporation and the holders of Securities shall
thereafter be determined, exercised and enforced hereunder subject in all
respects to such modifications and amendments, and all the terms and conditions
of any such supplemental indenture shall be and be deemed to be part of the
terms and conditions of this Indenture for any and all purposes.

      SECTION 9.04. Notation on Securities.

      Securities authenticated and delivered after the execution of any
supplemental indenture affecting such Securities pursuant to the provisions of
this Article IX may bear a notation in form approved by the Debenture Trustee as
to any matter provided for in such supplemental indenture. If the Corporation or
the Debenture Trustee shall so determine, new Securities so modified as to
conform, in the opinion of the Debenture Trustee and the Board of Directors, to
any modification of this Indenture contained in any such supplemental indenture
may be prepared and executed by the Corporation, authenticated by the Debenture
Trustee or the Authenticating Agent and delivered in exchange for the Securities
then outstanding.

6.02, may receive an Officers' Certificate and an Opinion of Counsel as
conclusive evidence that any supplemental indenture executed pursuant hereto
complies with the requirements of this Article IX.

      the Securities according to their tenor and the due and punctual
      performance and observance of all the covenants and conditions of this
      Indenture to be kept or performed by the Corporation shall be expressly

Trustee, of the obligation of due and punctual payment of the principal of and
Interest on all of the Securities and the due and punctual performance and

named herein as the party of the first part, and the Corporation thereupon shall
be relieved of any further liability or obligation hereunder or upon the
Securities. Such successor Person thereupon may cause to be signed, and may

as though all of such Securities had been issued at the date of the execution

                     SATISFACTION AND DISCHARGE OF INDENTURE

      SECTION 11.01. Discharge of Indenture.

      When (a) the Corporation shall deliver to the Debenture Trustee for
cancellation all Securities theretofore authenticated (other than any Securities
which shall have been destroyed, lost or stolen and which shall have been
replaced as provided in Section 2.07) and not theretofore cancelled, or (b) all
the Securities not theretofore cancelled or delivered to the Debenture Trustee
for cancellation shall have become due and payable, or are by their terms to
become due and payable within one year or are to be called for redemption within
one year under arrangements satisfactory to the Debenture Trustee for the giving
of notice of redemption, and the Corporation shall deposit with the Debenture
Trustee, in trust, funds sufficient to pay on the Maturity Date or upon
redemption all of the Securities (other than any Securities which shall have
been destroyed, lost or stolen and which shall have been replaced as provided in
Section 2.07) not theretofore cancelled or delivered to the Debenture Trustee
for cancellation, including principal and Interest due or to become due to the
Maturity Date or redemption date, as the case may be, but excluding, however,

Securities (1) theretofore repaid to the Corporation in accordance with the
provisions of Section 11.04, or (2) paid to any State or to the District of
Columbia pursuant to its unclaimed property or similar laws, and if in either
case the Corporation shall also pay or cause to be paid all other sums payable
hereunder by the Corporation, then this Indenture shall cease to be of further

2.11, 3.01, 3.02, 3.04, 4.01, 4.02, 5.02, 5.04, 6.05, 6.06, 6.10 and 11.04 and
Articles XIII-XVII, which shall survive until such Securities shall mature and

Debenture Trustee, on demand of the Corporation accompanied by any Officers'
Certificate and an Opinion of Counsel and at the cost and expense of the
Corporation, shall execute proper instruments acknowledging satisfaction of and
discharging this Indenture; the Corporation, however, hereby agrees to reimburse
the Debenture Trustee for any costs or expenses thereafter reasonably and
properly incurred by the Debenture Trustee in connection with this Indenture or
the Securities.

      SECTION 11.02. Deposited Moneys and U.S. Government Obligations to Be Held
in Trust by Debenture Trustee.

      Subject to the provisions of Section 11.04, all moneys and U.S. Government
Obligations deposited with the Debenture Trustee pursuant to Sections 11.01
shall be held in trust and applied by it to the payment, either directly or
through any paying agent (including the Corporation if acting as its own paying
agent), to the holders of the particular Securities for the payment of which
such moneys or U.S. Government Obligations have been deposited with the
Debenture Trustee, of all sums due and to become due thereon for principal and
Interest.

      SECTION 11.03. Paying Agent to Repay Moneys Held.

      Upon the satisfaction and discharge of this Indenture all moneys then held

upon written demand of the

                                      -59-
<PAGE>

Corporation, be repaid to it or paid to the Debenture Trustee, and thereupon
such paying agent shall be released from all further liability with respect to
such moneys.

      SECTION 11.04. Return of Unclaimed Moneys.

      Any moneys deposited with or paid to the Debenture Trustee or any paying
agent for payment of the principal of or Interest on Securities and not applied
but remaining unclaimed by the holders of Securities for two years after the
date upon which the principal of or Interest on such Securities, as the case may
be, shall have become due and payable, shall be repaid to the Corporation by the
Debenture Trustee or such paying agent on written demand; and the holder of any
of the Securities shall thereafter look only to the Corporation for any payment
which such holder may be entitled to collect and all liability of the Debenture
Trustee or such paying agent with respect to such moneys shall thereupon cease.

                                  ARTICLE XII
                    IMMUNITY OF INCORPORATORS, STOCKHOLDERS,
                             OFFICERS AND DIRECTORS

      SECTION 12.01. Indenture and Securities Solely Corporate Obligations.

      No recourse for the payment of the principal of or Interest on any
Security, or for any claim based thereon or otherwise in respect thereof, and no
recourse under or upon any obligation, covenant or agreement of the Corporation
in this Indenture, or in any Security, or because of the creation of any
indebtedness represented thereby, shall be had against any incorporator,
stockholder, officer or director, as such, past, present or future, of the
Corporation or of any successor Person to the Corporation, either directly or
through the Corporation or any successor Person to the Corporation, whether by
virtue of any constitution, statute or rule of law, or by the enforcement of any
assessment or penalty or otherwise; it being expressly understood that all such
liability is hereby expressly waived and released as a condition of, and as a
consideration for, the execution of this Indenture and the issue of the
Securities.

                                  ARTICLE XIII
                        PURCHASE AT THE OPTION OF HOLDER
                             UPON CHANGE IN CONTROL
                            OR TERMINATION OF TRADING

      SECTION 13.01. Repurchase Right.

      In the event that a Change in Control or a Termination of Trading shall
occur while any of the Securities are outstanding, each Holder shall have the
right (the "Repurchase Right"), at the Holder's option to require the
Corporation to repurchase, and upon the exercise of such right the Corporation
shall repurchase, all of such Holder's Securities not theretofore called for
redemption, or any portion of the principal amount thereof that is equal to
$1,000.00 or any integral multiple thereof (provided that no single Security may
be repurchased in part unless the portion of the principal amount of such
Security to be outstanding after such repurchase is equal to $1,000.00 or
integral multiples thereof), on the date (the "Repurchase Date") that is thirty
(30) days after the Change in Control Effective Date or thirty (30) days after
the first date on which such Termination of Trading shall have occurred at a
purchase price (the "Repurchase Price")

                                      -60-
<PAGE>

equal to 100% of the principal amount of the Securities to be repurchased, plus
accrued and unpaid Interest to, but excluding, the date of repurchase.

      SECTION 13.02. Notices, Method of Exercised Repurchase Right.

      As promptly as practicable following either (i) the date the Corporation
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 Corporation shall give to all Holders of Securities notice of the
Change in Control transaction or the Termination of Trading and of the
Repurchase Right set forth herein arising as a result thereof (the "Company
Notice"). The Corporation shall also deliver a copy of such notice to the
Debenture Trustee, in its capacity as such and as Property Trustee. Each notice
of a Repurchase Right shall state:

            (i) a brief description of the event or events constituting the
      Change in Control or the Termination of Trading and the Repurchase Date;

            (ii) the date by which the Repurchase Right must be exercised, which
      shall be the second (2nd) Business Day prior to the Repurchase Date;

            (iii) the Repurchase Price;

            (iv) a description of the procedure which a Holder must follow to
      exercise a Repurchase Right, and the place or places where such
      Securities, are to be surrendered for payment of the Repurchase Price and
      accrued and unpaid Interest, if any;

            (v) that on the Repurchase Date the Repurchase Price and accrued and
      unpaid Interest, if any, will become due and payable upon each such
      Security designated by the Holder to be repurchased, and that Interest
      thereon shall cease to accrue on and after said date;

            (vi) the Conversion Rate then in effect and the place where such
      Securities may be surrendered for conversion;

            (vii) the Securities as to which a Repurchase Notice has been given
      may not thereafter be converted;

            (viii) the place or places where such Securities, together with the
      Repurchase Notice are to be delivered for payment of the Repurchase Price
      and accrued and unpaid Interest, if any;

            (ix) whether, in the case of a Change in Control, the Conversion
      Rate will be increased by a number of Make-Whole Shares upon conversion in
      accordance with the provisions of Section 17.04; and

            (x) whether, in the case of a Change in Control, the Corporation has
      determined to exercise its irrevocable Change in Control redemption right
      pursuant to

                                      -61-
<PAGE>

      Section 14.01(b), and, if it has, the Redemption Price and the Change in
      Control Redemption Premium.

      No failure of the Corporation to give the foregoing notices or defect
therein shall limit any Holder's right to exercise a Repurchase Right or affect
the validity of the proceedings for the repurchase of Securities.

      SECTION 13.03. Repurchase Date; Exercise of Right.

      (a) To exercise the repurchase right set forth in this Article XIII in
respect of all or a portion of the Securities, the Securityholder thereof shall
deliver to the Corporation and Debenture Trustee, no later than the second (2nd)
Business Day prior to the Repurchase Date, a notice substantially in the form
set forth on the reverse of the form of Security attached as Exhibit A hereto
(the "Repurchase Notice") setting forth the principal amount of Securities to be
repurchased and, if such Securities are in certificated form, surrender to the
Debenture Trustee the Securities to be repurchased, duly endorsed or assigned to
the Corporation or in blank. In addition, a holder of Preferred Securities may
exercise its right under the Trust Agreement to exchange such Preferred
Securities for Securities which shall be repurchased by the Corporation by
delivering to the Exchange Agent a Notice of Repurchase Election (as such term
is defined in the Declaration) setting forth the information required thereby
and directing the Exchange Agent (i) to exchange such Preferred Security for a
portion of the Securities held by the Trust (at an exchange rate of $1,000.00
principal amount of Securities for each Preferred Security), and (ii) to
immediately require the Corporation to repurchase such Securities on the
Repurchase Date, on behalf of such holder of Preferred Securities pursuant to
this Article XIII and, if such Preferred Securities are in certificated form,
surrendering such Preferred Securities, duly endorsed or assigned to the
Corporation or in blank. So long as any Preferred Securities are outstanding,
the Trust shall not exercise the Repurchase Right in respect of any Securities
except pursuant to a Notice of Repurchase Election delivered to the Exchange
Agent by a holder of Preferred Securities.

      (b) In the event a Repurchase Right shall be exercised in accordance with
the terms hereof, the Corporation shall pay or cause to be paid to the Debenture
Trustee the Repurchase Price in cash, as provided above, for payment to the
Holder on the Repurchase Date, payable in cash with respect to the Securities as
to which the Repurchase Right has been exercised.

      (c) If any Security (or portion thereof) surrendered for repurchase shall
not be so paid on the Repurchase Date, the principal amount of such Security (or
portion thereof, as the case may be) shall, until paid, bear Interest to the
extent permitted by applicable law from the Repurchase Date at the rate of
Interest on the Security.

            Any Security which is to be repurchased only in part shall be
surrendered to the Debenture Trustee (with, if the Corporation or the Debenture
Trustee so requires, due endorsement by, or a written instrument of transfer in
form satisfactory to the Corporation and the Debenture Trustee duly executed by
the Holder thereof or his attorney duly authorized in writing), and the
Corporation shall execute, and the Debenture Trustee shall authenticate and make
available for delivery to the Holder of such Security without service charge, a
new Security or Securities, containing identical terms and conditions, each in
an authorized denomination in

                                      -62-
<PAGE>

aggregate principal amount equal to and in exchange for the unrepurchased
portion of the principal of the Security so surrendered.

      The Corporation shall comply with the requirements of the Securities
Exchange Act of 1934 and any other securities laws and regulations thereunder to
the extent such laws and regulations are applicable in connection with the
repurchase of the Securities as a result of a Change in Control or Termination
of Trading.

                                  ARTICLE XIV
                            REDEMPTION OF SECURITIES

      SECTION 14.01. Special Event Redemption and Change in Control Redemption.

      (a) If a Special Event has occurred and is continuing, the Corporation
shall have the right, at any time following the occurrence of such Special
Event, upon (i) not less than forty-five (45) days written notice to the
Debenture Trustee and (ii) not less than thirty (30) days nor more than sixty
(60) days written notice to the Securityholders, to redeem the Securities, in
whole (but not in part), at the Redemption Price. The Redemption Price shall be
paid prior to 1:00 p.m., New York City time, on the date of such redemption or
such earlier time as the Corporation determines, provided that the Corporation
shall deposit with the Debenture Trustee an amount sufficient to pay the
Redemption Price by 10:00 a.m., New York City time, on the date such Redemption
Price is to be paid.

      (b) If the Corporation has announced a Change in Control (for purposes of
this Section 14.01 only, the exception from the definition of the term Change in
Control contained in Section 17.04(c)(ii) shall not apply), the Corporation
shall have the irrevocable right to redeem the Securities, in whole (but not in
part), at 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 Securities were converted on the Change in
Control Effective Date at the then prevailing Conversion Rate multiplied by the
Stock Price plus the Change in Control Redemption Premium. Amounts payable
pursuant to this Section 14.01(b) shall be paid prior to 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 Corporation determines, provided that
the Corporation shall deposit with the Debenture Trustee an amount sufficient to
pay the amount owing under this section by 10:00 a.m., New York City time, on
the date such amount is to be paid.

      SECTION 14.02. Optional Redemption by Corporation.

      (a) Subject to Section 14.01, the Securities shall not be redeemable at
the option of the Corporation prior to July 1, 2010. The Corporation shall have
the right to redeem the Securities, 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 per share of Common Stock for the ten (10)
consecutive Trading Days ending on the Trading Day prior to the mailing of the
notice of redemption exceeds 130% of the then prevailing Conversion Price. On
and after July 1,

                                      -63-
<PAGE>

2012, the Corporation shall have the right to redeem the Securities, in whole or
in part, at the Redemption Price.

      (b) If the Securities are only partially redeemed pursuant to this Section
14.02, the Securities to be redeemed shall be selected on a pro rata basis 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 Securityholders that would be required to hold Securities
with an aggregate principal amount of less than $5,000 but more than an
aggregate principal amount of zero as a result of such pro rata redemption, the
Corporation shall redeem Securities of each such Securityholder so that after
such redemption such Securityholder shall hold Securities either with an
aggregate principal amount of at least $5,000 or such Securityholder no longer
holds any Securities, and shall use such method (including, without limitation,
by lot) as the Corporation shall deem fair and appropriate, provided further
that any such proration may be made on the basis of the aggregate principal
amount of Securities held by each Securityholder and may be made by making such
adjustments as the Corporation deems fair and appropriate in order that only
Securities in denominations of $1,000.00 or integral multiples thereof shall be
redeemed. The Make-Whole Redemption Price or the Redemption Price, as the case
may be, shall be paid prior to 1:00 p.m., New York City time, on the date of
such redemption or at such earlier time as the Corporation determines, provided
that the Corporation shall deposit with the Debenture Trustee an amount
sufficient to pay the Make-Whole Redemption Price or the Redemption Price, as
the case may be, by 10:00 a.m., New York City time, on the date such Make-Whole
Redemption Price or the Redemption Price, as the case may be, is to be paid.

      SECTION 14.03. No Sinking Fund.

      The Securities are not entitled to the benefit of any sinking fund.

      SECTION 14.04. Notice of Redemption; Selection of Securities.

      In case the Corporation shall desire to exercise the right to redeem all,
or, as the case may be, any part of the Securities in accordance with their
terms, it shall fix a date for redemption and shall mail a notice of such
redemption at least thirty (30) and not more than sixty (60) days prior to the
date fixed for redemption to the holders of Securities to be so redeemed as a
whole or in part at their last addresses as the same appear on the Security
Register. For purposes of the calculation of the date of redemption and the
dates on which notices are given pursuant to this Section 14.04, a redemption
notice shall be deemed to be given on the day such notice is first mailed by
first-class mail, postage prepaid, to holders. 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 by mail or any defect in the notice to the holder of any Security
designated for redemption as a whole or in part shall not affect the validity of
the proceedings for the redemption of any other Security.

      Each such notice of redemption shall specify the CUSIP number of the
Securities to be redeemed, the date fixed for redemption, the price at which the
Securities are to be redeemed (or the method by which such price is to be
calculated), the place or places of payment that payment will be made upon
presentation and surrender of the Securities, that Interest accrued to the date

                                      -64-
<PAGE>

fixed for redemption will be paid as specified in said notice, that on and after
said date Interest thereon or on the portions thereof to be redeemed will cease
to accrue, the then-current Conversion Price, the name and address of the paying
agent and the Conversion Agent, that the Securities called for redemption may be
converted at any time before 5:00 p.m. New York City time on the Business Day
immediately preceding the redemption date and that Securityholders who wish to
convert Securities must satisfy the requirements in the Indenture and the
Securities. If less than all the Securities are to be redeemed, the notice of
redemption shall specify the amount of the Securities to be redeemed. In case
any Security is to be redeemed in part only, the notice of redemption shall
state the portion of the principal amount thereof to be redeemed and shall state
that on and after the date fixed for redemption, upon surrender of such
Security, a new Security or Securities in principal amount equal to the portion
thereof that has not been redeemed will be issued.

      By 10:00 a.m. New York City time on the redemption date specified in the
notice of redemption given as provided in this Section, the Corporation will
deposit with the Debenture Trustee or with one or more paying agents an amount
of money sufficient to redeem on the redemption date all the Securities so
called for redemption at the appropriate Redemption Price or Make-Whole
Redemption Price, as the case may be.

      The Corporation will give the Debenture Trustee notice not less than
thirty (30) days prior to the redemption date as to the aggregate principal
amount of Securities to be redeemed and the Debenture Trustee shall select, in
such manner as in its sole discretion it shall deem appropriate and fair, the
Securities or portions thereof (in integral multiples of $1,000.00, except as
otherwise set forth in the applicable form of Security) to be redeemed.

      SECTION 14.05. Payment of Securities Called for Redemption.

      If notice of redemption has been given to Securityholders as provided in
Section 14.04, the Securities or portions of Securities with respect to which
such notice has been given shall become due and payable on the date and at the
place or places stated in such notice at the Redemption Price or Make-Whole
Redemption Price, as the case may be (subject to the rights of holders of
Securities at the close of business on a regular record date to receive Interest
in respect of an Interest Payment Date occurring on or prior to the Redemption
Date), and on and after said date (unless the Corporation shall default in the
payment of such Securities at the Redemption Price or Make-Whole Redemption
Price, as the case may be) Interest on the Securities or portions of Securities
so called for redemption shall cease to accrue. On presentation and surrender of
such Securities at a place of payment specified in said notice, the said
Securities or the specified portions thereof shall be paid and redeemed by the
Corporation at the Redemption Price or Make-Whole Redemption Price, as the case
may be (subject to the rights of holders of Securities at the close of business
on a regular record date to receive Interest in respect of an Interest Payment
Date occurring on or prior to the Redemption Date).

      Upon presentation of any Security redeemed in part only, the Corporation
shall execute and the Debenture Trustee shall authenticate and make available
for delivery to the holder thereof, at the expense of the Corporation, a new
Security or Securities of authorized denominations, in principal amount equal to
the portion of the Security so presented that has not been redeemed.

                                      -65-
<PAGE>

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

      SECTION 14.06. Conversion Arrangement on Call for Redemption.

      In connection with any redemption of Securities, the Corporation 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 Trustee in trust for the Holders, on or before the Redemption
Date, an amount not less than the applicable Redemption Price or Make-Whole
Redemption Price, as the case may be, of such Securities. Notwithstanding
anything to the contrary contained in this Article XIV, the obligation of the
Corporation to pay the Redemption Price or Make-Whole Redemption Price, as the
case may be, 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 Trustee prior
to the Redemption Date, any Securities not duly surrendered for conversion by
the Holders thereof, may, at the option of the Corporation, be deemed, to the
fullest extent permitted by law, acquired by such purchasers from such Holders
and (notwithstanding anything to the contrary contained in Article XVII)
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
Corporation, the Debenture 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
Corporation for the redemption of Securities. Without the Debenture Trustee's
prior written consent, no arrangement between the Corporation 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 Debenture Trustee as set forth in this Indenture, and the Corporation agrees
to indemnify the Debenture 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
Corporation and such purchasers, including advancement of the costs and expenses
incurred by the Debenture 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 this Indenture. Nothing in
the preceding sentence shall be deemed to limit the rights, privileges,
immunities and protections afforded to the Debenture Trustee in Article VI.
Nothing in this Section 14.06 shall affect the right of the Holders to receive
the full Redemption Price or Make-Whole Redemption Price, as the case may be, on
the Redemption Date.

                                   ARTICLE XV
                           SUBORDINATION OF SECURITIES

      SECTION 15.01. Securities Subordinate to Senior Indebtedness of the
Corporation.

      The Corporation covenants and agrees, and each Holder of a Security, by
its acceptance thereof, likewise covenants and agrees, that, to the extent and
in the manner hereinafter set forth in this Article XV, the payment of the
principal of and any premium and Interest on each and all of the Securities are
hereby expressly made subordinate and subject in right of payment to the prior
payment in full of all Senior Indebtedness of the Corporation. No provision of
this Article XV

                                      -66-
<PAGE>

shall prevent the occurrence of any Default or Event of Default hereunder.

      SECTION 15.02. No Payment When Senior Indebtedness of the Corporation in
Default; Payment Over of Proceeds Upon Dissolution, Etc.

(a) In the event and during the continuation of any default by the Corporation
in the payment of any principal of or any premium or interest on any Senior
Indebtedness of the Corporation (following any grace period, if applicable) when
the same becomes due and payable, whether at maturity or at a date fixed for
prepayment or by declaration of acceleration or otherwise, then, upon written
notice of such default to the Corporation by the holders of such Senior
Indebtedness of the Corporation or any trustee therefor, unless and until such
default shall have been cured or waived or shall have ceased to exist, no direct
or indirect payment (in cash, property, securities, by set-off or otherwise)
shall be made or agreed to be made on account of the principal of or any
Interest on any of the Securities or any obligations of the Corporation ranking
on a parity with the Securities unless the Securities participate on a pro rata
basis, or in respect of any redemption, repayment, retirement, purchase or other
acquisition of any of the Securities or any obligations of the Corporation
ranking on a parity with the Securities unless the Securities participate on a
pro rata basis.

(b) In the event of a bankruptcy, insolvency or other proceeding described in
clause (g) or (h) of the definition of Event of Default (each such event, if
any, herein sometimes referred to as a "Proceeding"), all Senior Indebtedness of
the Corporation (including any interest thereon accruing after the commencement
of any such proceedings) shall first be paid in full before any payment or
distribution, whether in cash, securities or other property, shall be made to
any Holder of any of the Securities on account thereof. Any payment or
distribution, whether in cash, securities or other property (other than
securities of the Corporation or any other entity provided for by a plan of
reorganization or readjustment the payment of which is subordinate, at least to
the extent provided in these subordination provisions with respect to the
indebtedness evidenced by the Securities, to the payment of all Senior
Indebtedness of the Corporation at the time outstanding and to any securities
issued in respect thereof under any such plan of reorganization or
readjustment), which would otherwise (but for these subordination provisions) be
payable or deliverable in respect of the Securities shall be paid or delivered
directly to the holders of Senior Indebtedness of the Corporation in accordance
with the priorities then existing among such holders until all Senior
Indebtedness of the Corporation (including any interest thereon accruing after
the commencement of any Proceeding) shall have been paid in full.

(c) In the event of any Proceeding, after payment in full of all sums owing with
respect to Senior Indebtedness of the Corporation, the Holders of the
Securities, together with the holders of any obligations of the Corporation
ranking on a parity with the Securities, shall be entitled to be paid from the
remaining assets of the Corporation the amounts at the time due and owing on

obligations before any payment or other distribution, whether in cash, property

and such other obligations. If, notwithstanding the foregoing, any payment or
distribution of any character or any security, whether in cash, securities or
other property (other than securities of the Corporation or any other entity
provided for by a plan of reorganization or readjustment the payment of which is
subordinate, at least to the extent provided in these subordination provisions
with respect to the indebtedness evidenced by the Securities, to the payment of
all Senior Indebtedness of the Corporation at the time outstanding and to any
securities issued in respect thereof under any such plan of reorganization or
readjustment) shall be received by the Debenture Trustee or any Holder in
contravention of any of the terms hereof and before all Senior Indebtedness of
the Corporation shall have been paid in full, such payment or distribution or
security shall be received in trust for the benefit of, and shall be paid over
or delivered and transferred to, the holders of the Senior Indebtedness of the
Corporation at the time outstanding in accordance with the priorities then
existing among such holders for application to the payment of all Senior
Indebtedness of the Corporation remaining unpaid, to the extent necessary to pay
all such Senior Indebtedness of the Corporation (including any interest thereon
accruing after the commencement of any Proceeding) in full. In the event of the
failure of the Debenture Trustee or any Holder to endorse or assign any such
payment, distribution or security, each holder of Senior Indebtedness of the
Corporation is hereby irrevocably authorized to endorse or assign the same.

(d) The Debenture Trustee and the Holders, at the expense of the Corporation,
shall take such reasonable action (including the delivery of this Indenture to
an agent for any holders of Senior Indebtedness of the Corporation or consent to
the filing of a financing statement with respect hereto) as may, in the opinion
of counsel designated by the holders of a majority in principal amount of the
Senior Indebtedness of the Corporation at the time outstanding, be necessary or
appropriate to assure the effectiveness of the subordination effected by these
provisions.

remedies or powers of any secured creditor of the Corporation in respect of any
security interest the creation of which is not prohibited by the provisions of
this Indenture.

(f) The securing of any obligations of the Corporation, otherwise ranking on a
parity with the Securities or ranking junior to the Securities, shall not be
deemed to prevent such obligations from constituting, respectively, obligations
ranking on a parity with the Securities or ranking junior to the Securities.

      SECTION 15.03. Payment Permitted if No Default.

      Nothing contained in this Article XV or elsewhere in this Indenture or in
any of the Securities shall prevent (a) the Corporation, at any time, except
during the pendency of the conditions described in paragraph (a) of Section
15.02 or of any Proceeding referred to in Section 15.02, from making payments at
any time of principal of or Interest on the Securities or (b) the application by
the Debenture Trustee of any moneys deposited with it hereunder to the payment
of or on account of the principal of and Interest on the Securities or the
retention of such payment by the Holders, if, at the time of such application by
the Debenture Trustee, it did not have knowledge (in accordance with Section
15.08) that such payment would have been prohibited by the provisions of this
Article XV.

      SECTION 15.04. Subrogation to Rights of Holders of Senior Indebtedness of
the Corporation.

Subject to the payment in full of all amounts due or to become due on all Senior
Indebtedness of the Corporation, or the provision for such payment in cash or
cash equivalents or otherwise in a manner satisfactory to the holders of Senior
Indebtedness of the Corporation, the Holders of the Securities shall be
subrogated to the extent of the payments or distributions made to the holders of
such Senior Indebtedness of the Corporation pursuant to the provisions of this
Article XV (equally and ratably with the holders of all indebtedness of the
Corporation that by its express terms is subordinated to Senior Indebtedness of
the Corporation to substantially the same extent as the Securities are
subordinated to the Senior Indebtedness of the Corporation and is entitled to
like rights of subrogation by reason of any payments or distributions made to
holders of such Senior Indebtedness of the Corporation) to the rights of the
holders of such Senior Indebtedness of the Corporation to receive payments and
distributions of cash, property and securities applicable to the Senior
Indebtedness of the Corporation until the principal of and Interest on the
Securities shall be paid in full. For purposes of such subrogation, no payments
or distributions to the holders of the Senior Indebtedness of the Corporation of
any cash, property or securities to which the Holders of the Securities or the
Debenture Trustee would be entitled except for the provisions of this Article
XV, and no payments made pursuant to the provisions of this Article XV to the
holders of Senior Indebtedness of the Corporation by Holders of the Securities
or the Debenture Trustee, shall, as among the Corporation, its creditors other
than holders of Senior Indebtedness of the Corporation, and the Holders of the
Securities, be deemed to be a payment or distribution by the Corporation to or
on account of the Senior Indebtedness of the Corporation.

      SECTION 15.05. Provisions Solely to Define Relative Rights.

      The provisions of this Article XV are intended solely for the purpose of
defining the relative rights of the Holders of the Securities on the one hand
and the holders of Senior Indebtedness of the Corporation on the other hand.
Nothing contained in this Article XV or elsewhere in this Indenture or in the
Securities is intended to or shall (a) impair, as between the Corporation and
the Holders of the Securities, the obligations of the Corporation, which are
absolute and unconditional, to pay to the Holders of the Securities the
principal of and Interest on the Securities as and when the same shall become
due and payable in accordance with their terms, (b) affect the relative rights
against the Corporation of the Holders of the Securities and creditors of the
Corporation other than their rights in relation to the holders of Senior
Indebtedness of the Corporation or (c) prevent the Debenture Trustee or the
Holder of any Security (or to the extent expressly provided herein, the holder
of any Preferred Security) from exercising all remedies otherwise permitted by
applicable law upon default under this Indenture, including filing and voting
claims in any Proceeding, subject to the rights, if any, under this Article XV
of the holders of Senior Indebtedness of the Corporation to receive cash,
property and securities otherwise payable or deliverable to the Debenture
Trustee or such Holder.

      SECTION 15.06. Debenture Trustee to Effectuate Subordination.

      The Each Holder of a Security by his or her acceptance thereof authorizes

may be necessary or appropriate to

                                      -69-
<PAGE>

acknowledge or effectuate the subordination provided in this Article XV and
appoints the Debenture Trustee his or her attorney-in-fact for any and all such
purposes.

      SECTION 15.07. No Waiver of Subordination Provisions.

(a) No right of any present or future holder of any Senior Indebtedness of the
Corporation to enforce subordination as herein provided shall at any time in any
way be prejudiced or impaired by any act or failure to act on the part of the
Corporation or by any act or failure to act, in good faith, by any such holder,
or by any noncompliance by the Corporation with the terms, provisions and
covenants of this Indenture, regardless of any knowledge thereof that any such
holder may have or be otherwise charged with.

(b) Without in any way limiting the generality of paragraph (a) of this Section
15.07, the holders of Senior Indebtedness of the Corporation may, at any time
and from to time, without the consent of or notice to the Debenture Trustee or
the Holders of the Securities, without incurring responsibility to such Holders
of the Securities and without impairing or releasing the subordination provided
in this Article XV or the obligations hereunder of such Holders of the
Securities to the holders of Senior Indebtedness of the Corporation, do any one
or more of the following: (i) change the manner, place or terms of payment or
extend the time of payment of, or renew or alter, Senior Indebtedness of the
Corporation, or otherwise amend or supplement in any manner Senior Indebtedness
of the Corporation or any instrument evidencing the same or any agreement under
which Senior Indebtedness of the Corporation is outstanding, (ii) sell,
exchange, release or otherwise deal with any property pledged, mortgaged or
otherwise securing Senior Indebtedness of the Corporation, (iii) release any
Person liable in any manner for the payment of Senior Indebtedness of the

Corporation and any other Person.

      SECTION 15.08. Notice to Debenture Trustee.

(a) The Corporation shall give prompt written notice to a Responsible Officer of
the Debenture Trustee of any fact known to the Corporation that would prohibit
the making of any payment to or by the Debenture Trustee in respect of the
Securities. Notwithstanding the provisions of this Article XV or any other
provision of this Indenture, the Debenture Trustee shall not be charged with
knowledge of the existence of any facts that would prohibit the making of any
payment to or by the Debenture Trustee in respect of the Securities, unless and
until a Responsible Officer of the Debenture Trustee shall have received written
notice thereof from the Corporation or a holder of Senior Indebtedness of the
Corporation or from any trustee, agent or representative therefor; and before
the receipt of any such written notice, the Debenture Trustee, subject to the
provisions of Article VI of this Indenture, shall be entitled in all respects to
assume that no such facts exist; provided, however, that if the Debenture
Trustee shall not have received the notice provided for in this Section 15.08 at
least two Business Days prior to the date upon which by the terms hereof any
monies may become payable for any purpose (including, the payment of the
principal of and Interest on any Security), then, anything herein contained to
the contrary notwithstanding, the Debenture Trustee shall have full power and
authority to receive such monies and to apply the same to the purpose for which
they were received and shall not be affected by any notice to the contrary that
may be received by it within two Business Days prior to such date.

                                      -70-

(b) The Debenture Trustee shall be entitled to rely on the delivery to it of a
written notice by a Person representing himself or herself to be a holder of
Senior Indebtedness of the Corporation (or a trustee, agent, representative or
attorney-in-fact therefor) to establish that such notice has been given by a
holder of Senior Indebtedness of the Corporation (or a trustee, agent,
representative or attorney-in-fact therefor). In the event that the Debenture
Trustee determines in good faith that further evidence is required with respect
to the right of any Person as a holder of Senior Indebtedness of the Corporation
to participate in any payment or distribution pursuant to this Article XV, the
Debenture Trustee may request such Person to furnish evidence to the reasonable
satisfaction of the Debenture Trustee as to the amount of Senior Indebtedness of
the Corporation held by such Person, the extent to which such Person is entitled
to participate in such payment or distribution and any other facts pertinent to
the rights of such Person under this Article XV, and if such evidence is not
furnished, the Debenture Trustee may defer any payment to such Person pending
judicial determination as to the right of such Person to receive such payment.

      SECTION 15.09. Reliance on Judicial Order or Certificate of Liquidating
Agent.

      Upon any payment or distribution of assets of the Corporation referred to
in this Article XV, the Debenture Trustee and the Holders of the Securities
shall be entitled to conclusively rely upon any order or decree entered by any
court of competent jurisdiction in which such Proceeding is pending, or a
certificate of the trustee in bankruptcy, receiver, liquidating trustee,
custodian, assignee for the benefit of creditors, agent or other Person making
such payment or distribution, delivered to the Debenture Trustee or to the
Holders of Securities, for the purpose of ascertaining the Persons entitled to
participate in such payment or distribution, the holders of the Senior
Indebtedness of the Corporation and other indebtedness of the Corporation, the
amount thereof or payable thereon, the amount or amounts paid or distributed
thereon and all other facts pertinent thereto or to this Article XV.

      SECTION 15.10. Debenture Trustee Not Fiduciary for Holders of Senior
Indebtedness of the Corporation.

      The Debenture Trustee, in its capacity as trustee under this Indenture,
shall not be deemed to owe any fiduciary duty to the holders of Senior
Indebtedness of the Corporation and shall not be liable to any such holders if
it shall in good faith mistakenly pay over or distribute to Holders of
Securities or to the Corporation or to any other Person cash, property or
securities to which any holders of Senior Indebtedness of the Corporation shall
be entitled by virtue of this Article XV or otherwise. With respect to the
holders of Senior Indebtedness of the Corporation, the Debenture Trustee
undertakes to perform or to observe only such of its covenants and obligations
as are specifically set forth in this Article XV, and no implied covenants or
obligations with respect to the holders of such Senior Indebtedness shall be
read into this Indenture against the Debenture Trustee.

      Nothing in this Article XV shall apply to claims of, or payments to, the
Debenture Trustee under or pursuant to Section 6.06.

      SECTION 15.11. Rights of Debenture Trustee as Holder of Senior
Indebtedness of the Corporation; Preservation of Debenture Trustee's Rights.

      The Debenture Trustee in its individual capacity shall be entitled to all
the rights set forth in this Article XV with respect to any Senior Indebtedness
of the Corporation that may at any time be held by it, to the same extent as any
other holder of Senior Indebtedness of the Corporation, and nothing in this
Indenture shall deprive the Debenture Trustee of any of its rights as such
holder.

      SECTION 15.12. Article Applicable to Paying Agents.

      If at any time any paying agent other than the Debenture Trustee shall
have been appointed by the Corporation and be then acting hereunder, the term
"Debenture Trustee" as used in this Article XV shall in such case (unless the
context otherwise requires) be construed as extending to and including such
paying agent within its meaning as fully for all intents and purposes as if such
paying agent were named in this Article XV in addition to or in place of the
Debenture Trustee; provided, that Sections 15.08 and 15.11 shall not apply to
the Corporation or any Affiliate of the Corporation if the Corporation or such
Affiliate acts as paying agent.

      (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

                                      -76-
<PAGE>

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 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 principal amount of
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 principal amount of
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 16.02(a), transferred automatically and by operation of
this Indenture to the Share Trust to be held in accordance with Section 16.02,
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 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 16.01(b)(i) above would
nonetheless be continuing (for example, where the ownership of Equity Stock or
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 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 16.01(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 Securities (or any combination thereof) in violation of Section
16.01(b), or that a purported Transfer of Common Stock or Equity Stock or
Securities or any combination thereof has otherwise taken place in violation of
Section 16.01(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 16.01(b)(i) shall automatically result in
the Transfer described in Section 16.01(c), irrespective of any action (or
non-action) by the Board of Directors, except as provided in Section 16.01(f).

      (e) Notice of Restricted Transfer.

      (i) Any Person who acquires or attempts to acquire Common Stock, Equity
Stock or Securities in violation of Section 16.01(b), and any Person who is a
Purported Record Transferee or a Purported Beneficial Transferee of shares of
Common Stock, Equity Stock or Securities that are transferred to a Share Trust
under Section 16.01(c), shall immediately give written notice to the Corporation
of such event, shall submit to the Corporation such number of

                                      -77-
<PAGE>

shares of Common Stock or Equity Stock or amount of 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 Securities of the Corporation (treating the Securities as
Equity Stock for this purpose) and each Person (including a Security holder of
record) who is holding 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 Securities
by such Person, if it concludes that the ownership of Common Stock and/or Equity
Stock and/or 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 Securities pursuant to Section 16.01(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 an opinion of counsel satisfactory to the Board of
Directors that concludes that the ownership of Equity Stock or 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

                                      -78-
<PAGE>

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 16.01(f)(ii) is intended to limit or modify the restrictions on
ownership contained in Section 16.01(b) hereof and the authority of the Board of
Directors under this Section 16.01(f).

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

      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 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.

      (i) Ambiguity. In the case of an ambiguity in the application of any of
the provisions, including any definition contained in Section 16.01(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 16.02 SHARES-IN-TRUST.

      (a) Share Trust. Any shares of Equity Stock or Securities transferred to a
Share Trust and designated Shares-in-Trust pursuant to Section 16.01(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.

                                      -80-
<PAGE>

Any transfer to a Share Trust, and subsequent designation of shares of Equity
Stock or Securities as Shares-in-Trust, pursuant to Section 16.01(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 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
Securities of the same class and series. When transferred to the Permitted
Transferee in accordance with the provisions of Section 16.02(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, distributions and
interest payments, 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 Securities
and shall hold such dividends, distributions or interest payments 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,
distributions or interest payments received by it that (i) are attributable to
any shares of Equity Stock or 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, distribution or
interest payment paid to the Purported Record Transferee (or Purported
Beneficial Transferee, if applicable), including, if necessary, withholding any
portion of future dividends, distributions or interest payments payable on
shares of Equity Stock or Securities Beneficially Owned by the Person who, but
for the provisions of Section 16.01(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,
distributions and interest payments 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, ratably with each other holder of shares of Equity
Stock or 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 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 16.02(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 Securities and which Transfer resulted in the transfer
of the shares or Securities to the Share Trust, the price per share or price of
the Security, if any, such Purported Record Transferee paid for the shares of
Equity Stock or 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
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 Securities to the Share Trust, the price per share or
price of the Security equal to the Market Price on the date

                                      -81-
<PAGE>

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 Securities prior to the discovery by the Corporation that the
shares of Equity Stock or 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 Securities under Section 16.01(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 16.02(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 Securities so
acquired as Shares-in-Trust under Section 16.01(c). Upon the designation by the
Share Trustee of a Permitted Transferee in accordance with the provisions of
this Section 16.02(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 principal amount of 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
16.02(f).

      (f) Compensation to Record Holder of Shares of Equity Stock or 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 16.02(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 Securities and which Transfer resulted in
the transfer of the Securities or shares to the Share Trust, the price per
share, or price for the Security, if any, such Purported Record Transferee (or
the Purported Beneficial Transferee, if applicable) paid for the shares of
Equity Stock or 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 Securities or shares (e.g., if the
Securities or 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
Securities or shares to the Share Trust, the price per share or price of the
Securities equal to the Market Price on the date of such Non-Transfer Event or
Transfer, and (ii) the price per share or

                                      -82-
<PAGE>

price of the Securities received by the Share Trustee of the Share Trust from
the sale or other disposition of such Shares-in-Trust in accordance with Section
16.02(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 16.02(f) shall be distributed to the
Charitable Beneficiary in accordance with the provisions of Section 16.02(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 16.02 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, or price for the
Securities, 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 16.01(e).

                                  ARTICLE XVII
                            CONVERSION OF SECURITIES

      SECTION 17.01. Conversion Rights.

      (a) Subject to and upon compliance with the provisions of this Article
XVII, the Securities are convertible, at the option of the Securityholder, at
any time before 5:00 pm, New York City time, on the Business Day immediately
preceding the date of repayment of such Securities, whether at stated maturity
or upon redemption, 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
in aggregate principal amount of Securities (equal to an initial Conversion
Price of $25.57 per share of Common Stock), subject to adjustment as described
in this Article XVII (the "Conversion Rate"). Subject to Section 17.01(b) and
(c), a Securityholder may convert any portion of the principal amount of the
Securities into that number of fully paid and nonassessable shares of Common
Stock (calculated as to each conversion to the nearest 1/100th of a share)
obtained by multiplying (x) the quotient obtained by dividing the principal
amount of the Securities to be converted by $1,000.00 by (y) the Conversion
Rate. In case a Security or portion thereof is called for redemption, such
conversion right in respect of the Security or portion so called shall expire at
5:00 p.m., New York City time on the Business Day immediately preceding the
corresponding redemption date, unless the Corporation defaults in making the
payment due upon redemption.

      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

                                      -83-
<PAGE>

by an amount equal to 120% of the Average Closing Price. Notwithstanding the
foregoing, if the application of the foregoing were to 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). Notwithstanding the forgoing, in no event will
the Conversion Rate or Maximum Conversion Rate be adjusted as described in this
Section 17.01(a) to a Conversion Rate that is greater than the Maximum Cash
Adjusted Conversion Rate.

      The Conversion Rate shall be adjusted in certain instances as provided in
paragraphs (a), (b), (c), (d) or (e) of Section 17.03 hereof.

      (b) Unless the Corporation shall have made the election set forth in
Section 17.01(c), upon conversion of the Securities, the Corporation may satisfy
its obligation to deliver shares of Common Stock in the manner set forth in this
Section 17.01(b) by electing to pay cash to Holders of Securities surrendered
for conversion in lieu of all or a portion of the shares of Common Stock
issuable upon conversion of such Securities. Within two (2) Business Days
following the Conversion Date, the Corporation shall deliver to the Holder,
through the Conversion Agent, written notice of whether such Securities shall be
converted into Common Stock or paid in cash or a combination of cash and Common
Stock, and if applicable, the percentage of each share of Common Stock that will
be paid in cash in lieu of Common Stock. The amount of cash payable in such
event in respect of the shares of Common Stock otherwise issuable upon
conversion shall equal the product of (1) the percentage of each share of Common
Stock otherwise issuable upon conversion which the Corporation elects to pay in
cash, (2) the number of shares of Common Stock otherwise issuable upon
conversion of such Security and (3) the average of the Closing Prices of the
Common Stock for each of the five (5) consecutive Trading Days commencing on the
third (3rd) Trading Day following the Conversion Date, appropriately adjusted to
take into account the occurrence during such period of stock splits and similar
events. If the Corporation shall have notified the Holder that all of such
Securities shall be converted into Common Stock or a combination of cash and
Common Stock, the Corporation shall deliver to the Holder through the Conversion
Agent, no later than three (3) Trading Days following the last Trading Day of
the applicable five (5) consecutive Trading Day period, a certificate for the
number of whole shares of Common Stock issuable upon the conversion and, if
applicable, cash in lieu of such Common Stock and cash in lieu of any fractional
shares pursuant to Section 17.02(c). The Corporation may not change its election
with respect to the consideration to be delivered upon conversion of a Security
once the Corporation has notified the Holder in accordance with this paragraph.

      (c) At any time prior to the Maturity Date, the Corporation shall have the
option to unilaterally and irrevocably elect to settle its obligation to deliver
shares of Common Stock with respect to Securities to be converted following such
election in cash, and, if applicable, shares of

                                      -84-

Common Stock. If the Corporation shall make this election, then if a Holder
surrenders its Securities for conversion, such holder will receive, in respect
of each $1,000.00 principal amount of Securities surrendered for conversion:

            (i) cash in an amount equal to the lesser of (A) $1,000.00 and (B)
      the Conversion Value (the "Required Cash Amount"); and

            (ii) if the Conversion Value is greater than $1,000.00, a number of
      shares of Common Stock (the "Remaining Shares"), equal to the sum of the
      Daily Share Amounts for each of the five (5) consecutive Trading Days in
      the Conversion Reference Period, subject to the right of the Corporation
      to deliver cash in lieu of all or a portion of such Remaining Shares as
      described below.

      On any day prior to the first Trading Day of the applicable Conversion
Reference Period, the Corporation may specify a percentage of the Daily Share
Amount that will be settled in cash (the "Cash Percentage") and will notify the
Securityholder of such Cash Percentage through written notice to the Debenture
Trustee (the "Cash Percentage Notice"). If the Corporation elects to specify a
Cash Percentage, the amount of cash that the Corporation will deliver in respect
of each Trading Day in the applicable Conversion Reference Period will equal the
product of: (1) the Cash Percentage, (2) the Daily Share Amount for such Trading
Day, and (3) the Volume Weighted Average Price of the Common Stock for such
Trading Day (provided that after the consummation of a Change in Control in
which the consideration is comprised entirely of cash, the amount used in this
clause (3) will be the cash price per share of Common Stock received by holders
of Common Stock in such Change in Control). The number of shares deliverable in
respect of each Trading Day in the applicable Conversion Reference Period will
be a percentage of the Daily Share Amount equal to 100% minus the Cash
Percentage. If the Corporation does not specify a Cash Percentage by the start
of the applicable Conversion Reference Period, the Corporation shall settle 100%
of the Daily Share Amount for each Trading Day in the applicable Conversion
Reference Period with shares of Common Stock; provided, however, that the
Corporation will pay cash in lieu of fractional shares otherwise issuable upon
conversion of such Security, pursuant to Section 17.02(c). The Corporation may,
at its option, revoke any Cash Percentage Notice through written notice to the
Debenture Trustee prior to the start of the applicable Conversion Reference
Period.

      In the event of a stock split, combination, dividend or any other event
resulting in an adjustment to the Conversion Rate pursuant to Sections 17.03(a),
(b), (c), (d) or (e), during the applicable Conversion Reference Period,
appropriate adjustment to the equation for calculating Conversion Value and
Remaining Shares shall be made, as determined by the Board of Directors.

      The cash and any shares of Common Stock due upon conversion of the
Securities shall be delivered through the Conversion Agent as promptly as
practicable following the end of the Conversion Reference Period applicable to
the Securities being converted.

      SECTION 17.02. Conversion Procedures.

      (a) To convert all or a portion of the Securities, the Securityholder
thereof shall deliver to the Conversion Agent a Conversion Request setting forth
the principal amount of Securities to be converted, together with the name or
names, if other than the Securityholder, in which the shares of Common Stock
should be issued upon conversion and, if such Securities are in certificated
form, surrender to the Conversion Agent the Securities to be converted, duly
endorsed or assigned to the Corporation or in blank. In addition, a holder of
Preferred Securities may exercise its right under the Declaration to exchange
such Preferred Securities for Securities which shall be converted into Common
Stock by delivering to the Conversion Agent a Conversion Request setting forth
the information called for by the preceding sentence and directing the
Conversion Agent (i) to exchange such Preferred Security for a portion of the
Securities held by the Trust (at an exchange rate of $1,000.00 principal amount
of Securities for each Preferred Security), and (ii) to immediately convert such
Securities, on behalf of such Securityholder, into Common Stock pursuant to this
Article XVII and, if such Preferred Securities are in certificated form,
surrendering such Preferred Securities, duly endorsed or assigned to the
Corporation or in blank. So long as any Preferred Securities are outstanding,
the Trust shall not convert any Securities into shares of Common Stock except
pursuant to a Conversion Request delivered to the Conversion Agent by a holder
of Preferred Securities.

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

                                      -86-
<PAGE>

conversion of such Security shall not be payable, and the Corporation shall not
make nor be required to make any other payment, adjustment or allowance with
respect to accrued but unpaid Interest 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). If any
Security called for redemption is converted, any money deposited with the
Debenture Trustee or with any paying agent or so segregated and held in trust
for the redemption of such Security shall (subject to any right of the
Securityholder) be paid to the Corporation upon Corporation Request or, if then
held by the Corporation, shall be discharged from such trust.

      In addition to the provisions of the foregoing paragraph, in the event
that the Corporation shall have called the Securities for redemption and a
Securityholder shall have converted some or all of its Securities, in addition
to the amounts owing upon conversion pursuant to the provisions of this Article
XVII, the Securityholder 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 if any such Make-Whole Payment Price shall then be owing in connection
with the Securities.

      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 deliveries were received (the "Conversion Date")
by the Conversion Agent from the Securityholder or from a holder of the
Preferred Securities effecting a conversion thereof pursuant to its conversion
rights under the Declaration, as the case may be. The person or persons entitled
to receive the Common Stock issuable upon such conversion shall be treated for
all purposes as a record holder or holders of such Common Stock as of the
Conversion Date.

      (b) Subject to any right of the Securityholder, the fair market value of
the fixed number of shares of Common Stock into which the 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 Interest on such 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 principal amount at maturity of the portion of Securities so converted.

      (c) No fractional shares of Common Stock shall be issued as a result of
conversion. Subject to the immediately following sentence, in lieu of any such
fractional shares, the Corporation 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 Securities or Preferred Securities,
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
Securityholder or the holder of the Preferred Securities so converted. In the
event that the conversion obligation is settled in accordance with the
provisions of Section 17.01(c), a Holder of a Security otherwise entitled to a
fractional share will receive cash equal to the applicable portion of the
arithmetic average of the Volume Weighted Average price of Common Stock for each
of the five (5) consecutive Trading Days of the Conversion Reference Period.

                                      -87-
<PAGE>

      (d) In the event of the conversion of any Security in part only, a new
Security or Securities for the unconverted portion thereof shall be issued in
the name of the Securityholder thereof upon the cancellation thereof in
accordance with Section 2.9.

      (e) In effecting the conversion transactions described in this Section
17.02, the Conversion Agent is acting as agent of the holders of Preferred
Securities (in the exchange of Preferred Securities for Securities) and as agent
of the Securityholders (in the conversion of Securities 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
Securities held by the Trust from time to time in connection with the conversion
of such Preferred Securities in accordance with this Article XVII, and (ii) to
convert all or a portion of the Securities into Common Stock and thereupon to
deliver such shares of Common Stock in accordance with the provisions of this
Article XVII and to deliver to the Trust a new Security or Securities for any
resulting unconverted principal amount.

      (f) Any certificates representing shares of Common Stock issuable upon
conversion of the Securities shall bear any legend required by Section 2.06.

      (g) The Corporation shall at all times reserve and keep available out of
its authorized and unissued Common Stock, solely for issuance upon the
conversion of the Securities, 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 Securities then outstanding. Notwithstanding the
foregoing, the Corporation shall be entitled to deliver upon conversion of
Securities, shares of Common Stock reacquired and held in the treasury of the
Corporation (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 Securities shall be duly authorized, validly issued and
fully paid and nonassessable. The Debenture Trustee shall deliver the shares of
Common Stock received upon conversion of the Securities to the converting
Securityholder free and clear of all liens, charges, security interests and
encumbrances, except for United States withholding taxes and backup withholding
taxes.

      SECTION 17.03. Conversion Rate Adjustments.

      The Conversion Rate shall be subject to adjustment (without duplication)
from time to time as follows:

      (a) In case the Corporation shall, while any of the Securities are
outstanding,

            (i) pay a dividend or make a distribution on its Common Stock
      payable in shares of its Common Stock,

            (ii) subdivide its shares of Common Stock,

            (iii) combine its outstanding shares of Common Stock into a smaller
      number of shares, or

                                      -88-
<PAGE>

            (iv) issue by recapitalization or reclassification of its shares of
      Common Stock any shares of capital stock of the Corporation,

then the Conversion Rate in effect immediately prior to such action shall be
adjusted so that the Holder of a Security thereafter converted may receive the
number of shares of Capital Stock of the Corporation which such Holder would
have owned immediately following such action if such Holder had converted the
Security immediately prior to such action; provided, however, that no adjustment
shall be made to the Conversion Rate pursuant to this Section 17.03(a) as a
result of any transaction which results in an adjustment to the Conversion Rate
in accordance with Section 17.04.

      The adjustment shall become effective immediately after the record date in
the case of a dividend or distribution and immediately after the effective date
in the case of a subdivision, combination or reclassification.

      If after an adjustment a Holder of a Security upon conversion of such
Security may receive shares of two or more classes of Capital Stock of the
Corporation, the Conversion Rate shall thereafter be subject to adjustment upon
the occurrence of an action taken with respect to any such class of Capital
Stock as is contemplated by this Article XVII with respect to the Common Stock,
on terms comparable to those applicable to Common Stock in this Article XVII.

      (b) In case the Corporation shall, while any of the Securities are
outstanding, distribute any rights, warrants or options to all holders of its
Common Stock entitling them, for a period expiring within sixty (60) days after
the record date for such distribution, to purchase shares of Common Stock at a
price per share less than the Average Closing Price, the Conversion Rate shall
be adjusted in accordance with the formula:

                         R' =  R  x         (O + N)
                                       ----------------
                                       (O + (N x P) /M)

            where:

            R'=   the adjusted Conversion Rate.

            R =   the current Conversion Rate.

            O =   the number of shares of Common Stock outstanding on the record
                  date for the distribution to which this Section 17.03(b) is
                  being applied.

            N =   the number of additional shares of Common Stock offered
                  pursuant to the distribution.

            P =   the offering price per share of the additional shares.

            M   = the Average Closing Price, minus, in the case of (i) a
                  distribution to which Section 17.03(a)(iv) applies or (ii) a
                  distribution to which Section 17.03(c) applies, for which, in
                  each case, (x) the record date shall occur on or before the
                  record date for the distribution to which this Section
                  17.03(b) applies and

                                      -89-
<PAGE>

                  (y) the Ex-Dividend Time shall occur on or after the date of
                  the first public announcement for the distribution to which
                  this Section 17.03(b) applies, the fair market value (on the
                  record date for the distribution to which this Section
                  17.03(b) applies) of the

                        (1) Capital Stock of the Corporation distributed in
                  respect of each share of Common Stock in such Section
                  17.03(a)(iv) distribution and

                        (2) assets of the Corporation or debt securities or any
                  rights, warrants or options to purchase securities of the
                  Corporation distributed in respect of each share of Common
                  Stock in such Section 17.03(c) distribution.

      The Board of Directors shall determine fair market values for the purposes
of this Section 17.03(b).

      In the event the Corporation makes a distribution pursuant to this Section
17.03(b) which has a per share value equal to more than 15% of the Closing Price
of shares of Common Stock on the day preceding the declaration date for such
distribution, the Corporation will be required to give notice to the holders of
Securities at least twenty (20) days prior to the Ex-Dividend Date for such
distribution.

      The adjustment shall become effective immediately after the record date
for the determination of shareholders entitled to receive the rights, warrants
or options to which this Section 17.03(b) applies. If all of the shares of
Common Stock subject to such rights, warrants or options have not been issued
when such rights, warrants or options expire, then the Conversion Rate shall
promptly be readjusted to the Conversion Rate that would then be in effect had
the adjustment upon the issuance of such rights, warrants or options been made
on the basis of the actual number of shares of Common Stock issued upon the
exercise of such rights, warrants or options.

      No adjustment shall be made under this Section 17.03(b) if the application
of the formula stated above in this Section 17.03(b) would result in a value of
R' that is equal to or less than the value of R.

      (c) (i) In case the Corporation shall, while any of the Securities are
outstanding, distribute to all holders of its Common Stock any of its assets
(including shares of any Subsidiary or business unit of the Corporation, but
excluding distributions of Capital Stock or equity interests referred to in
Section 17.03(c)(ii)), or debt securities or any rights, warrants or options to
purchase securities of the Corporation (including securities or cash, but
excluding (x) distributions of Capital Stock referred to in Section 17.03(a) and
distributions of rights, warrants or options referred to in Section 17.03(b) and
(y) cash dividends or other cash distributions referred to in Section 17.03(d)),
the Conversion Rate shall be adjusted, subject to the provisions of Section
17.03(c)(iii), in accordance with the formula:

                        R'  =     R x M
                               ------------
                                  M - F

                                      -90-
<PAGE>

      where:

      R' =   the adjusted Conversion Rate.

      R  =   the current Conversion Rate.

      M  =   the Average Closing Price, minus, in the case of a distribution
             to which Section 17.03(a)(iv) applies, for which (i) the record
             date shall occur on or before the record date for the
             distribution to which this Section 17.03(c)(i) applies and (ii)
             the Ex-Dividend Time shall occur on or after the date of the Time
             of Determination for the distribution to which this Section
             17.03(c)(i) applies, the fair market value (on the record date
             for the distribution to which this Section 17.03(c)(i) applies)
             of any Capital Stock of the Corporation distributed in respect of
             each share of Common Stock in such Section 17.03(a)(iv)
             distribution.

      F  =   the fair market value (on the record date for the distribution to
             which this Section 17.03(c)(i) applies) of the assets,
             securities, rights, warrants or options to be distributed in
             respect of each share of Common Stock in the distribution to
             which this Section 17.03(c)(i) is being applied (including, in
             the case of cash dividends or other cash distributions giving
             rise to an adjustment, all such cash distributed concurrently).

      The Board of Directors shall determine fair market values for the purposes
of this Section 17.03(c)(i).

      The adjustment shall become effective immediately after the record date
for the determination of shareholders entitled to receive the distribution to
which this Section 17.03(c)(i) applies.

      (ii) In case the Corporation shall, while any of the Securities are
outstanding, pay a dividend or make a distribution to all holders of its Common
Stock consisting of Capital Stock of any class or series, or similar equity
interests, of or relating to a Subsidiary or other business unit of the
Corporation, then the Conversion Rate shall be adjusted in accordance with the
formula:

                                     R' = R x (1 + F/M)

      R' =   the adjusted Conversion Rate.

      R  =   the current Conversion Rate.

      M  =   the average of the Post-Distribution Prices of the Capital Stock
             for the ten (10) Trading Days commencing on and including the fifth
             (5th) Trading Day after the date on which "ex-dividend trading"
             commences for such dividend or distribution on the principal United
             States exchange or market which such securities are then listed or
             quoted (the "Ex-Dividend Date").

                                      -91-
<PAGE>

      F  =   the fair market value of the securities distributed in respect of
             each share of Common Stock to which this Section 17.03(c)(ii) shall
             apply which shall equal the number of securities distributed in
             respect of each share of Common Stock multiplied by the average of
             the Post-Distribution Prices of those securities distributed for
             the ten (10) Trading Days commencing on and including the fifth
             (5th) Trading Day after the Ex-Dividend Date.

      "Post-Distribution Price" of Capital Stock or any similar equity interest
on any date means the closing per unit sale price (or, if no closing sale price
is reported, the average of the bid and ask prices or, if more than one in
either case, the average of the average bid and the average ask prices) on such
date for trading of such units on a "when issued" basis without due bills (or
similar concept) as reported in the composite transactions for the principal
United States securities exchange on which such Capital Stock or equity interest
is traded or, if the Capital Stock or equity interest, as the case may be, is
not listed on a United States national or regional securities exchange, as
reported by the National Association of Securities Dealers Automated Quotation
System or by the National Quotation Bureau Incorporated; provided that if on any
date such units have not traded on a "when issued" basis, the Post-Distribution
Price shall be the closing per unit sale price (or, if no closing sale price is
reported, the average of the bid and ask prices or, if more than one in either
case, the average of the average bid and the average ask prices) on such date
for trading of such units on a "regular way" basis without due bills (or similar
concept) as reported in the composite transactions for the principal United
States securities exchange on which such Capital Stock or equity interest is
traded or, if the Capital Stock or equity interest, as the case may be, is not
listed on a United States national or regional securities exchange, as reported
by the National Association of Securities Dealers Automated Quotation System or
by the National Quotation Bureau Incorporated. In the absence of such quotation,
the Corporation shall be entitled to determine the Post-Distribution Price on a
basis as it considers reasonably appropriate to determine the fair market value
of such Capital Stock.

      (iii) In the event that, with respect to any distribution to which Section
17.03(c)(i) would otherwise apply, the difference between "M-F" as defined in
the formula set forth in Section 17.03(c)(i) is less than $1.00 or "F" is equal
to or greater than "M", then the adjustment provided by Section 17.03(c)(i)
shall not be made.

      (iv) In the event the Corporation makes a distribution pursuant to this
Section 17.03(c) which has a per share value equal to more than 15% of the
Closing Price of shares of Common Stock on the day preceding the declaration
date for such distribution, the Corporation will be required to give notice to
the holders of Securities at least twenty (20) days prior to the Ex-Dividend
Date for such distribution.

(d) In case the Corporation shall, on or after August 1, 2007 and while any of
the Securities are outstanding, distribute to all or substantially all holders
of its Common Stock any regular quarterly cash dividend or other distribution
paid exclusively in cash (excluding any dividend or distribution in connection
with the liquidation, dissolution or winding up of the Corporation, whether
voluntary or involuntary), the Conversion Rate shall be adjusted in accordance
with the formula:

                        R' =  R  x       M
                                     --------

                                      -92-
<PAGE>

                                      (M - C)

      where,

      R' =  the adjusted Conversion Rate;

      R  =  the Conversion Rate in effect immediately prior to the Time of
            Determination;

      M  =  the average of the Closing Prices of the Common Stock for the five
            (5) consecutive Trading Days prior to the Trading Day immediately
            preceding the Time of Determination; and

      C  =  the amount in cash per share the Corporation distributes to holders
            of the Common Stock (and for which no adjustment has been made) in
            excess of an amount of cash equal to the Threshold Dividend Yield.

      Notwithstanding the forgoing, in no event will the Conversion Rate or
Maximum Conversion Rate be adjusted as described in this Section 17.03(d) to a
Conversion Rate that is greater than the Maximum Cash Adjusted Conversion Rate.

      The Maximum Cash Adjusted Conversion Rate shall be subject to adjustment
on each occasion on which the Conversion Rate shall be adjusted (other than on
account of adjustments the Conversion Rate resulting from the application of the
provisions of this Section 17.03(d)) by multiplying the then applicable Maximum
Cash Adjusted 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.

      (e) In case the Corporation shall, while any of the Securities are
outstanding, make a payment of cash or other consideration to holders of Common
Stock in respect of a tender offer or exchange offer, other than an odd-lot
offer, for the Common Stock, and the value of the aggregate cash and other
consideration paid for such Common Stock, expressed as an amount per share of
Common Stock validly tendered or exchanged pursuant to such tender offer or
exchange offer, exceeds the Closing Price of the Common Stock on the Trading Day
immediately following the last time (the "Expiration Time") on which tenders or
exchanges may be made pursuant to the tender or exchange offer, then the
Conversion Rate shall be adjusted in accordance with the formula:

                        R' =  R x    F + (P x O)
                                    -------------
                                       O' x P

      where,

      R  =   the Conversion Rate in effect on the Expiration Time;

      R' =   the Conversion Rate in effect immediately after the Expiration
             Time;

      F  =   the fair market value (as determined by the Board of Directors) of
             the aggregate value of all cash and any other consideration paid or
             payable for shares of Common

                                      -93-
<PAGE>

             Stock validly tendered or exchanged and not withdrawn as of the
             Expiration Time (the "Purchased Shares");

      O  =   the number of shares of Common Stock outstanding immediately after
             the Expiration Time less any Purchased Shares;

      O' =   the number of shares of Common Stock outstanding immediately after
             the Expiration Time, including any Purchased Shares; and

      P  =   the Closing Price of the Common Stock on the Trading Day next
             succeeding the Expiration Time.

      Such increase (if any) shall become effective immediately prior to the
opening of business on the day following the Expiration Time. In the event that
the Corporation is obligated to purchase shares pursuant to any such tender
offer, but the Corporation is prevented by applicable law from effecting any
such purchases or all such purchases are rescinded, the Conversion Rate shall
again be adjusted to be the Conversion Rate that would then be in effect if such
tender or exchange offer had not been made. If the application of this Section
17.03(e) to any tender or exchange offer would result in a decrease in the
Conversion Rate, no adjustment shall be made for such tender or exchange offer
under this Section 17.03(e).

      (f) The Corporation may make such increases in the Conversion Rate, in
addition to those required by Subsections (a) through (e), as it considers to be
advisable to avoid or diminish any income tax to holders of Common Stock or
rights to purchase Common Stock resulting from any dividend or distribution of
stock (or rights to acquire stock) or from any event treated as such for income
tax purposes. The Corporation from time to time may, to the extent permitted by
law, increase the Conversion Rate by any amount for any period of time if the
period is at least twenty (20) days upon notice by the Corporation of at least
fifteen (15) days, the increase is irrevocable during the period, and the Board
of Directors shall have made a determination that such increase would be in the
best interest of the Corporation, which determination shall be conclusive.
Whenever the Conversion Rate is increased pursuant to the preceding sentence,
the Corporation shall mail to Securityholders of record a notice of the increase
at least fifteen (15) days prior to the date the increased Conversion Rate takes
effect, and such notice shall state the increased Conversion Rate and the period
it shall be in effect.

      (g) Anything in this Section 17.03 to the contrary notwithstanding, no
adjustment of the Conversion Rate will be made upon: (a) the issuance of any
shares of Common Stock pursuant to any present or future plan providing for the
reinvestment of dividends or interest payable on securities of the Corporation
and the investment of additional optional amounts in shares of Common Stock
under any such plan, or (b) the issuance of any shares of Common Stock or
options or rights pursuant to any present or future employee benefit plan or
program, or (c) the issuance of any shares of Common Stock pursuant to any
option, warrant, right or any exercisable, exchangeable or convertible security
outstanding as of the date on which the Securities are first issued, or (d) the
issuance of rights under any shareholder rights plan, or (e) a change in the par
value or a change to no par value of the Common Stock. To the extent the
Securities become convertible into cash, no adjustments need be made thereafter
as to the cash and interest will not accrue on the cash.

                                      -94-
<PAGE>

      (h) The Corporation shall not issue or deliver Common Stock upon
conversion of any Security to the extent that such issuance of shares of Common
Stock would exceed the REIT Cap (unless the Corporation issues a related waiver
from the REIT Cap) or the Exchange Cap. If the preceding sentence precludes the
Corporation from issuing or delivering shares of Common Stock in complete or
partial satisfaction of its obligations to convert a Security surrendered for
conversion, the Corporation shall settle such conversion in cash or in a
combination of cash and shares of Common Stock (but only to the extent not
prohibited by the preceding sentence, in each case, pursuant to the provisions
of Section 17.01(b) or 17.01(c), as applicable).

      "REIT Cap" means beneficial ownership by a Person of (i) Common Stock of
the Corporation in excess of 6.5% of the more restrictive of the total number or
value of the outstanding shares of Common Stock of the Corporation, (ii) shares
of equity stock of the Corporation in excess of 6.5% of the more restrictive of
the total number or value of the outstanding shares of equity stock of the
Corporation, (iii) shares of the Corporation's equity stock if such acquisition
would result in the Corporation being "closely held" under Section 856(h) of the
Code, (iv) shares of the Corporation's equity stock if such acquisition would
result in the equity stock being beneficially owned by fewer than 100 persons
(determined without reference to any rules of attribution under the Code), (v)
shares of the Corporation's equity stock if such acquisition would cause the
Corporation to fail to qualify as a real estate investment trust under the Code
or (vi) shares of the Corporation's Common Stock or equity stock in violation of
any of the further restrictions set forth in the Corporation's charter.

      "Exchange Cap" means any issuance of Common Stock that would require the
approval of the Corporation's Shareholders under Rule 312.03 of the New York
Stock Exchange Listed Company Manual.

      (i) No adjustment in the Conversion Rate shall be required unless such
adjustment would require an increase or decrease of at least 1% in the
Conversion Rate; provided, however, that any adjustments which by reason of this
Section 17.03(i) are not required to be made shall be carried forward and taken
into account in determining whether any subsequent adjustment shall be required.
The adjusted Conversion Rate will be rounded to four decimal places.

      (j) If any action would require adjustment of the Conversion Rate pursuant
to more than one of the provisions described above, only one adjustment shall be
made and such adjustment shall be the amount of adjustment that has the highest
absolute value to the Securityholders.

      SECTION 17.04. Conversion Rate Adjustments Upon Change in Control.

      (a) If a Change in Control occurs and a Holder elects to convert its
Securities in connection with such Change in Control, the Corporation will
increase the applicable Conversion Rate for the Securities surrendered for
conversion by a number of additional shares of Common Stock (the "Make-Whole
Shares"), as described in this Section 17.04. A conversion of Securities will be
deemed for the purposes of this Section 17.04 to be "in connection with" a
Change in Control transaction if the notice of conversion of the Securities is
received by the Conversion Agent from and including the date that is fifteen
(15) Trading Days prior to the anticipated

                                      -95-
<PAGE>

effective date of the Change in Control, up to and including the Trading Day
prior to the related purchase date.

      The number of Make-Whole Shares will be determined by reference to the
table below and is based on the date which such Change in Control transaction
becomes effective (the "Change in Control Effective Date") and the price (the
"Stock Price") paid per share of Common Stock in such Change in Control
transaction. If the holders of Common Stock receive only cash in the Change in
Control transaction, the Stock Price shall be the cash amount paid per share of
Common Stock. Otherwise, the Stock Price shall be the average of the Closing
Prices of the Common Stock on the five (5) consecutive Trading Days up to but
excluding the Change in Control Effective Date.

      The Stock Prices set forth in the first column of the table below will be
adjusted as of any date on which the Conversion Rate is adjusted. The adjusted
Stock Prices will equal the Stock Prices applicable immediately prior to such
adjustment, multiplied by a fraction, the numerator of which is the applicable
Conversion Rate immediately prior to the adjustment giving rise to the Stock
Price adjustment and the denominator of which is the applicable Conversion Rate
as so adjusted. In addition, the number of additional Make-Whole Shares shall be
subject to adjustment in the same manner as the Conversion Rate is in accordance
with the provisions of Section 17.03(a)-(e).

      If the exact Stock Prices and effective dates are not set forth in the
table, then:

            (i) if the Stock Price is between two Stock Price amounts in the
      table or the effective date is between two dates in the table, the
      Make-Whole Shares issued upon conversion of the Securities will be
      determined by a straight-line interpolation between the number of
      Make-Whole Shares set forth for the higher and lower Stock Price amounts
      and the two dates in the table, based on a 365-day year,

            (ii) if the Stock Price exceeds $200.00 per share, subject to
      adjustment as set forth herein, no Make-Whole Shares will be issued upon
      conversion of the Securities; and

            (iii) if the Stock Price is less than $21.31 per share, subject to
      adjustment as set forth herein, no Make-Whole Shares will be issued upon
      conversion of the Securities.

      (b) A "Change in Control" shall be deemed to have occurred at such time as
either of the following events shall occur:

                                      -96-
<PAGE>

            (i) There shall be consummated any consolidation or merger of the
      Corporation pursuant to which the Common Stock would be converted into any
      combination of cash, securities or other property, in each case other than
      a consolidation or merger of the Corporation in which the holders of
      Common Stock immediately prior to the consolidation or merger have,
      directly or indirectly, at least a majority of the total voting power in
      the aggregate of all classes of capital stock of the continuing or
      surviving corporation immediately after such consolidation or merger; or

            (ii) There is a report on Schedule 13D or TO (or any successor
      schedule, form or report) pursuant to the Exchange Act, disclosing that
      any person, including such person's Affiliates or Associates (for these
      purposes only, as the term "person" is used in Section 13(d)(3) or Section
      14(d)(2) of the Exchange Act) has become the beneficial owner (as the term
      "beneficial owner" is defined under Rule 13d-3 or any successor rule or
      regulation promulgated under the Exchange Act) of 50% or more of the
      voting power of the Common Stock or other capital stock into which the
      Common Stock is reclassified or changed; provided, however, that a person
      shall not be deemed to be a beneficial owner of, or to own beneficially,
      (A) any securities tendered pursuant to a tender or exchange offer made by
      or on behalf of such person or any such person's Affiliates or Associates
      until such tendered securities are accepted for purchase or exchange
      thereunder, or (B) any securities if such beneficial ownership (1) arises
      solely as a result of a revocable proxy delivered in response to a proxy
      or consent solicitation made pursuant to the applicable rules and
      regulations under the Exchange Act, and (2) is not also then reportable on
      Schedule 13D (or any successor schedule) under the Exchange Act.

      (c) Notwithstanding the provisions of Section 17.04(b),

            (i) a Change in Control shall not be deemed to have occurred by
      virtue of the Corporation, any subsidiary, any employee stock ownership
      plan or any other employee benefit plan of the Corporation or any
      subsidiary, or any person holding the Common Stock for or pursuant to the
      terms of any such employee benefit plan, filing or becoming obligated to
      file a report under or in response to Schedule 13D or Schedule TO (or any
      successor schedule, form or report) under the Exchange Act disclosing
      beneficial ownership by it of shares of the Common Stock, whether in
      excess of 50% or otherwise (provided, however, this Section 17.04(c)(i)
      shall not apply to filings or obligations to file a report under or in
      response to Schedule 13D or Schedule TO (or any successor schedule, form
      or report) under the Exchange Act relating to or arising from any of the
      foregoing's participation in any acquisition of the Corporation in which a
      party that is not an Affiliate of the Corporation has a material
      interest); and

            (ii) it will not constitute a Change in Control if 100% of the
      consideration for the Common Stock (excluding cash payments for fractional
      shares and cash payments made in respect of dissenters' appraisal rights
      and cash payment of the required cash payment, if any) in the transaction
      or transactions constituting the Change in Control consists of common
      stock traded on a United States national securities exchange or quoted on
      the NASDAQ Stock Market, or which will be so traded or quoted when issued
      or exchanged in connection with the Change in Control, and as a result of
      such

                                      -97-
<PAGE>

      transaction or transactions the Securities become convertible solely into
      such common stock.

      SECTION 17.05. Share Exchange, Consolidation, Merger or Sale of Assets.

      In the case of the following events (each, a "business combination"):

            (1) Any recapitalization, reclassification or change of the Common
      Stock, other than a change in par value, or from par value to no par
      value, or from no par value to par value, or as a result of a subdivision
      or combination;

            (2) A consolidation, merger or binding share exchange of the
      Corporation with another Person; or

            (3) A sale, conveyance or lease to another corporation of all or
      substantially all of the Corporation's property and assets in each case as
      a result of which holders of Common Stock are entitled to receive stock,
      other securities, other property or assets (including cash or any
      combination thereof) with respect to or in exchange for Common Stock,

then the Corporation or the successor or purchasing corporation, as the case may
be, shall execute a supplemental indenture which shall provide that the Holders
of the Securities then outstanding will be entitled thereafter to convert
Securities into the kind and amount of shares of stock, other securities or
other property or assets (including cash or any combination thereof) which they
would have owned or been entitled to receive upon such business combination had
such Securities been converted into Common Stock immediately prior to such
business combination. In the event holders of Common Stock have the opportunity
to elect the form of consideration to be received in such business combination,
the Corporation will make adequate provision whereby the Holders of the
Securities shall have a reasonable opportunity to determine the form of
consideration into which all of the Securities, treated as a single class, shall
be convertible from and after the effective date of such business combination.
Such determination shall be based on the weighted average of elections made by
Holders of the Securities who participate in such determination, shall be
subject to any limitations to which all of the holders of Common Stock are
subject, such as pro-rata reductions applicable to any portion of the
consideration payable in such business combination and shall be conducted in
such a manner as to be completed by the date which is the earliest of (a) the
deadline for elections to be made by holders of Common Stock, and (b) two (2)
Trading Days prior to the anticipated effective date. The Corporation will
provide notice of the opportunity to determine the form of such consideration,
as well as notice of the determination made by Holders of the Securities (and
the weighted average of elections), by issuing a press release, or providing
other appropriate notice, and by providing a copy of such notice to the
Debenture Trustee. In the event the effective date is delayed beyond the
initially anticipated effective date, Holders of the Securities shall be given
the opportunity to make subsequent similar determinations in regard to such
delayed effective date. The Corporation may not become a party to any such
transaction unless its terms are materially consistent with the provisions of
this Section 17.05. None of the foregoing provisions shall affect the right of a
Holder of Securities to convert its Securities into shares of Common Stock prior
to the effective date of the business combination.

                                      -98-
<PAGE>

      The Corporation shall cause notice of the execution of such supplemental
indenture to be mailed to each holder, at the address of such holder as it
appears on the security Register, within twenty (20) days after execution
thereof. Failure to deliver such notice shall not affect the legality or
validity of such supplemental indenture.

      The above provisions of this Section 17.05 shall similarly apply to
successive reclassifications, mergers, consolidations, statutory share
exchanges, combinations, sales and conveyances.

      If this Section 17.05 applies to any event or occurrence, Section 17.03
shall not apply to such event or occurrence.

      SECTION 17.06. Notice of Adjustments of Conversion Rate.

      Whenever the Conversion Rate is adjusted as herein provided:

      (a) The Corporation shall compute the adjusted Conversion Rate and shall
prepare an Officers' Certificate setting forth the adjusted Conversion Rate and
showing in reasonable detail the facts upon which such adjustment is based, and
such certificate shall forthwith be filed with the Debenture Trustee, the
Conversion Agent and the transfer agent for the Preferred Securities and the
Securities; and

      (b) A notice stating that the Conversion Rate has been adjusted and
setting forth the adjusted Conversion Rate shall as soon as practicable be
mailed by the Corporation to all record holders of Preferred Securities and the
Securities at their last addresses as they appear upon the stock transfer books
of the Corporation and the Trust and the Corporation shall issue a press release
and publish such determination on the Corporation's website.

      SECTION 17.07. Prior Notice of Certain Events.

      In case the Corporation takes any action which would require an adjustment
to the Conversion Rate, there occurs any event to which the provisions of
Section 17.05 would apply or there is a dissolution or liquidation of the
Corporation, then the Corporation shall (1) if any Preferred Securities are
outstanding, cause to be filed with the Property Trustee and the transfer agent
for the Preferred Securities, and shall cause to be mailed to the holders of
record of the Preferred Securities, at their last addresses as they shall appear
upon the securities register of the Trust, or (2) shall cause to be mailed to
all Securityholders at their last addresses as they shall appear in the Security
Register, at least thirty (30) days prior to the applicable record or effective
date hereinafter specified, a notice briefly describing the event and stating
the proposed record of effective date. No failure to mail such notice or any
defect therein or in the mailing thereof shall affect the validity of the
corporate action required to be specified in such notice.

      SECTION 17.08. Debenture Trustee Not Responsible for Determining
Conversion Rate or Adjustments.

      Neither the Debenture Trustee nor any Conversion Agent shall at any time
be under any duty or responsibility to any Securityholder to calculate the
Conversion Rate or to determine whether any facts exist which may require any
adjustment of the Conversion Rate, or with

                                      -99-
<PAGE>

respect to the nature or extent of any such adjustment when made, or with
respect to the method employed, or herein or in any supplemental indenture
provided to be employed, in making the same. Neither the Debenture Trustee nor
any Conversion Agent shall be accountable with respect to the validity or value
(or the kind of account) of any shares of Common Stock or of any securities or
property, which may at any time be issued or delivered upon the conversion of
any Security; and neither the Debenture Trustee nor any Conversion Agent makes
any representation with respect thereto. Neither the Debenture Trustee nor any
Conversion Agent shall be responsible for any failure of the Corporation to make
any cash payment or to issue, transfer or deliver any shares of Common Stock or
stock certificates or other securities or property upon the surrender of any
Security for the purpose of conversion, or to comply with any of the covenants
of the Corporation contained in Article III or this Article XVII.

TREATING THE SECURITIES AS EQUITY STOCK OR, ALTERNATIVELY, TREATING THE
SECURITIES AS THE COMMON STOCK INTO WHICH THEY ARE CONVERTIBLE (TO THE EXTENT

THEREUNDER), IF EITHER TREATMENT WOULD CAUSE THIS PROVISION TO BE VIOLATED, (IV)
NO PERSON MAY BENEFICIALLY OWN SHARES OF EQUITY STOCK OR SECURITIES OF AMERICAN

"CODE"), AND (V) NO PERSON MAY BENEFICIALLY OWN SHARES OF EQUITY STOCK OR

QUALIFY AS A REAL ESTATE INVESTMENT TRUST UNDER THE CODE. ANY PERSON WHO
ATTEMPTS OR PROPOSES TO BENEFICIALLY OWN SHARES OF EQUITY STOCK OR SECURITIES OF
AMERICAN HOME MORTGAGE INVESTMENT CORP. OR ANY COMBINATION THEREOF IN EXCESS OF

                     American Home Mortgage Investment Corp.

                 9.75% JUNIOR SUBORDINATED CONVERTIBLE DEBENTURE
                                DUE JULY 1, 2037

American Home Mortgage Investment Corp., a Maryland corporation (the
"Corporation", which term includes any successor Person under the Indenture
hereinafter referred to), for value received, hereby promises to pay to
Wilmington Trust Company as Property Trustee for AHM Capital Trust I or
registered assigns, the principal sum of ONE HUNDRED TWENTY-EIGHT MILLION EIGHT
HUNDRED SIXTY-SIX THOUSAND DOLLARS ($128,866,000) on July 1, 2037 (the "Maturity
Date"), unless previously redeemed, repurchased or converted, and to pay
interest on the outstanding principal amount hereof from June 28, 2007, or from
the most recent interest payment date (each such date, an "Interest Payment
Date") to which interest has been paid or duly provided for, quarterly in
arrears on January 1, April 1, July 1 and October 1 of each year, commencing
October 1, 2007, at the rate of (i) 9.75% per annum until the principal hereof
shall have become due and payable, (ii) 9.75% per annum on any overdue
installment of Interest (to the extent that payment of such interest is
enforceable under applicable law) and (iii) 11.75% per annum for any period of
time during which any installment of Interest is overdue, in every case,
compounded quarterly, including any Liquidated Damages (as defined in the
Registration Rights Agreement) and any Additional Sums. The amount of Interest,
if any, payable on any Interest Payment Date shall be computed on the basis of a
360-day year of twelve 30-day months. In the event that any date on which the
principal of or Interest on this Security is payable is not a Business Day, then
the payment 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, then 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. Pursuant to the Indenture, in certain circumstances the Corporation will
be required to pay Additional Sums and Liquidated Damages with respect to this
Security.

      The Interest installment so payable, and punctually paid or duly provided
for, on any Interest Payment Date will, as provided in the Indenture, be paid to
the Person in whose name this Security (or one or more Predecessor Securities,
as defined in said Indenture) is registered at the close of business on the
regular record date for such interest installment, which shall be as of 5:00
p.m., New York City time, on the first day of the month, whether or not a
Business Day, in the month in which the relevant Interest Payment Date occurs.
Any such Interest installment not punctually paid or duly provided for shall
forthwith cease to be payable to the Holders on such regular record date and
shall be paid to the Person in whose name this Security (or one or more
Predecessor Securities) is registered at the close of business on a special
record date to be fixed by the Debenture Trustee for the payment of such
defaulted Interest, notice whereof shall be given to the holders of Securities
not less than ten (10) days prior to such special record date, or may be paid at
any time in any other lawful manner not inconsistent with the requirements of
any

                                      A-5
<PAGE>

securities exchange on which the Securities may be listed, and upon such notice
as may be required by such exchange, all as more fully provided in the
Indenture.

      The principal of and Interest on this Security shall be payable at the
office or agency of the Debenture Trustee maintained for that purpose in any
coin or currency of the United States of America that at the time of payment is
legal tender for payment of public and private debts; provided, however, that,
payment of Interest may be made at the option of the Corporation (i) by check
mailed to the holder at such address as shall appear in the Security Register or
(ii) by transfer to an account maintained by the Person entitled thereto,
provided that proper written transfer instructions have been received by the
relevant record date. Notwithstanding the foregoing, so long as the Holder of
this Security is the Property Trustee, the payment of the principal of and
Interest on this Security will be made at such place and to such account as may
be designated by the Property Trustee.

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

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

      The Company 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 Company 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 Preferred
Securities (including but not limited to all payments and proceeds with respect
to the Preferred 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.

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

      This Security is one of the Securities of the Corporation (herein
sometimes referred to as the "Securities"), specified in the Indenture, all
issued or to be issued under and pursuant to an Indenture, dated as of June 28,
2007 (the "Indenture"), duly executed and delivered between the Corporation and
Wilmington Trust Company as Debenture Trustee (the "Debenture Trustee"), to
which Indenture reference is hereby made for a description of the rights,
limitations of rights, obligations, duties and immunities thereunder of the
Debenture Trustee, the Corporation and the holders of the Securities.
Capitalized terms used but not defined herein shall have the meanings given to
them in the Indenture.

      1. Redemption. (a) Upon the occurrence and continuation of a Special
Event, the Corporation shall have the right, at any time following the
occurrence of such Special Event, to redeem this Security in whole (but not in
part) at the Redemption Price. In addition, the Corporation shall have the right
to redeem this Security, in whole or, in part from time to time, on or after
July 1, 2010 at the Make-Whole Redemption Price if the average Closing Price per
share of the Corporation's Common Stock the ten (10) consecutive Trading Days
ending on the Trading Day prior to the mailing of the notice of redemption
exceeds 130% of the then prevailing Conversion Price. On and after July 1, 2012,
the Corporation shall have the right to redeem the Securities, in whole or in
part, at the Redemption Price. Amounts payable pursuant to this paragraph 1(a)
and Section 14.01(a) of the Indenture shall be paid prior to 1:00 p.m., New York
City time, on the date of such redemption or at such earlier time as the
Corporation determines, provided, that the Corporation shall deposit with the
Debenture Trustee an amount sufficient to pay the Redemption Price or Make-Whole
Redemption Price, as the case may be, by 10:00 a.m. New York City time on the
date such Redemption Price or Make-Whole Redemption Price, as the case may be,
is to be paid. Any redemption pursuant to this paragraph will be made upon not
less than thirty (30) days nor more than sixty (60) days notice.

            (b) If the Corporation has announced a Change in Control, the
Corporation shall have the irrevocable right to redeem this Security, in whole
(but not in part), at 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 this Security was converted on the Change
in Control Effective Date at the then prevailing Conversion Rate multiplied by
the Stock Price plus the Change in Control Redemption Premium. Amounts payable
pursuant to this paragraph 1(b) and Section 14.01(b) of the Indenture shall be
paid prior to 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
Corporation determines, provided that the Corporation shall deposit with the
Debenture Trustee an amount sufficient to pay the amount owing under this
section by 10:00 a.m., New York City time, on the date such amount is to be
paid.

      If the Securities are only partially redeemed by the Corporation pursuant
to an optional redemption described in paragraph 1(a), the particular Securities
to be redeemed shall be selected on a pro rata basis 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
Securityholders that would be required to hold Securities with an aggregate
principal amount of less than $5,000 but more than an aggregate principal amount
of zero as a result of such pro rata redemption, the Corporation shall redeem
Securities of each such Securityholder so that after

                                      A-8
<PAGE>

such redemption such Securityholder shall hold Securities either with an
aggregate principal amount of at least $5,000 or such Securityholder no longer
holds any Securities and shall use such method (including, without limitation,
by lot) as the Corporation shall deem fair and appropriate, provided, further,
that any such proration may be made on the basis of the aggregate principal
amount of Securities held by each Securityholder thereof and may be made by
making such adjustments as the Corporation deems fair and appropriate in order
that only Securities in denominations of $1,000.00 or integral multiples thereof
shall be redeemed.

      In the event of redemption of this Security in part only, a new Security
or Securities for the portion hereof that has not been redeemed will be issued
in the name of the holder hereof upon the cancellation hereof.

      2. Conversion. Subject to and upon compliance with the provisions of
Article XVII of the Indenture, the Securities are convertible, at the option of
the Securityholder, at any time before 5:00 p.m., New York City time, on the
Business Day immediately preceding the date of repayment of this Security,
whether at stated maturity or upon redemption, 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 in aggregate principal amount of Securities (equal to
an initial conversion price of $25.57 per share of Common Stock), subject to
adjustment as described in the Indenture. A Securityholder may convert any
portion of the principal amount of the Securities into that number of fully paid
and nonassessable shares of Common Stock (calculated as to each conversion to
the nearest 1/100th of a share) in the manner prescribed by the Indenture. Upon
conversion of the Securities, the Corporation may satisfy its obligation to
deliver shares of Common Stock by delivering cash and/or shares of Common Stock,
all as set forth in Article XVII of the Indenture. In case a Security or portion
thereof is called for redemption, such conversion right in respect of the
Security or portion so called shall expire at 5:00 p.m., New York City time on
the Business Day immediately preceding the corresponding redemption date, unless
the Corporation defaults in making the payment due upon redemption.

      (b) To convert all or a portion of the Securities, the Securityholder
thereof shall deliver to the Conversion Agent a Conversion Request setting forth
the principal amount of Securities to be converted, together with the name or
names, if other than the Securityholder, in which the shares of Common Stock
should be issued upon conversion and, if such Securities are in certificated
form, surrender to the Conversion Agent the Securities to be converted, duly
endorsed or assigned to the Corporation or in blank. In addition, a holder of
Preferred Securities may exercise its right under the Declaration to exchange
such Preferred Securities for Securities which shall be converted into Common
Stock by delivering to the Conversion Agent a Conversion Request setting forth
the information called for by the preceding sentence and directing the
Conversion Agent (i) to exchange such Preferred Security for a portion of the
Securities held by the Trust (at an exchange rate of $1,000.00 principal amount
of Securities for each Preferred Security), and (ii) to immediately convert such
Securities, on behalf of such Securityholder, into Common Stock pursuant to
Article XVII of the Indenture and, if such Preferred Securities are in
certificated form, surrendering such Preferred Securities, duly endorsed or
assigned to the Corporation or in blank.

      (c) Except as described in this paragraph, no Interest will be payable on
Securities surrendered for conversion with respect to any Interest Payment Date
subsequent to

                                      A-9
<PAGE>

the date of conversion and neither the Trust nor the Corporation shall make, or
be required to make, any payment, allowance or adjustment for accumulated and
unpaid Interest, whether or not in arrears, on Securities surrendered for
conversion. If any 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 Interest Payment Date, the Securities surrendered for conversion must be
accompanied by payment in next day funds of an amount equal to the Interest
payment which the registered holder on such record date is to receive, and such
Securityholder shall be entitled to receive the Interest payable on the
subsequent Interest Payment Date on the portion of Securities to be converted,
notwithstanding the conversion thereof prior to such Interest Payment Date. The
previous sentence shall not apply in the case of Securities called for
redemption on a redemption date between a record date and a related Interest
Payment Date, in which event Interest with respect to such Securities shall be
payable to the extent provided in the Indenture. Except as otherwise set forth
above in this paragraph, in the case of any Security which is converted,
Interest which is payable after the date of conversion of such Security shall
not be payable, and the Corporation shall not make nor be required to make any
other payment, adjustment or allowance with respect to accrued but unpaid
Interest 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).

      (d) Subject to any right of the Securityholder, the fair market value of
the fixed number of shares of Common Stock into which the 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 Interest on such 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 principal amount at maturity of the portion of Securities so converted.

      (e) No fractional shares of Common Stock shall be issued as a result of
conversion, but in lieu thereof, the Corporation shall pay to the Conversion
Agent a cash adjustment in the amount determined in accordance with the
provisions of Article XVII of the Indenture.

      3. [Reserved]

      4. Repurchase. Upon the occurrence of a Change in Control or a Termination
of Trading, Holders shall have the right to require the Corporation to
repurchase all or any portion of their Securities that is an integral multiple
of $1,000.00 at a Repurchase Price equal to 100% of the principal amount of the
Securities to be repurchased, plus accrued and unpaid Interest to, but
excluding, the date of repurchase. To exercise the Repurchase Right following a
Change in Control or a Termination of Trading, the Securityholder shall be
required to deliver a Repurchase Notice and otherwise comply with the applicable
provisions of Article XIII of the Indenture. In addition, a holder of Preferred
Securities may exercise its right under the Declaration to exchange such
Preferred Securities for Securities which shall be repurchased by the
Corporation following a Change in Control by delivering to the Exchange Agent a
Notice of Repurchase Election and directing the Conversion Agent (i) to exchange
such Preferred Security for a portion of the Securities held by the Trust (at an
exchange rate of $1,000.00 principal amount of Securities for each Preferred
Security), and (ii) to immediately tender such Securities, on behalf

                                      A-10
<PAGE>

of such Securityholder, for repurchase pursuant to Article XIII of the Indenture
and, if such Preferred Securities are in certificated form, surrendering such
Preferred Securities, duly endorsed or assigned to the Corporation or in blank.

      5. Acceleration. In case an Event of Default, as defined in the Indenture,
shall have occurred and be continuing, the principal of all of the Securities
and all accrued and unpaid Interest thereon may be declared, and, in certain
cases, shall ipso facto become, due and payable, in each case, in the manner,
with the effect and subject to the conditions provided in the Indenture.

      6. Modification and Waiver. The Indenture contains provisions permitting
the Corporation and the Debenture Trustee, with the consent of the holders of a
majority in aggregate principal amount of the Securities at the time
outstanding, as defined in the Indenture, to execute supplemental indentures for
the purpose of adding any provisions to or changing in any manner or eliminating
any of the provisions of the Indenture or of modifying in any manner the rights
of the holders of the Securities; provided, however, that no such supplemental
indenture shall, without the consent of each holder of Securities then
outstanding and affected thereby, thereby (i) change the Maturity Date of any
Security, or reduce the principal amount of, or any installment of principal of
or Interest on the Securities; (ii) reduce the rate or extend the time of
payment of Interest; (iii) change any of the provisions of Article XIV of the
Indenture relating to redemption; (iv) change the Conversion Rate except as
provided in Section 17.03 and Section 17.04 of the Indenture with respect to
adjustment of the Conversion Rate, or otherwise change the right to convert the
Securities in a manner that would be adverse to Securityholders; (v) make the
principal of, or Interest payment on, the Securities payable in any coin or
currency other than that provided in the Indenture; (vi) change any obligation
of the Corporation to maintain an office or agency in the places and for the
purposes required by the Indenture or change the place of payment where the
Securities or Interest payment thereon is payable; (vii) impair or affect the
right of any holder of Securities to institute suit for the payment of the
Securities as provided in the Indenture; (viii) reduce the percentage of the
principal amount of the Securities required to consent to modify or amend the
Indenture or for any waiver of compliance with provisions of the Indenture as
stated in the Indenture or for waiver of Defaults as stated in the Indenture;
(ix) make any change adverse to a Holder with respect to the subordination
provisions of Article XV of the Indenture; or (x) modify any of the foregoing
provisions; provided, however, that if the Securities are held by the Trust, no
such modification or amendment referred to in clauses (i) through (x) shall be
effective until the holders of not less than a majority of the aggregate
liquidation amount of the Trust Securities shall have consented to such
modification or amendment; and provided further, that where a consent under the
Indenture would require the consent of the Securityholders of more than a
majority of the principal amount of the Securities, such modification or
amendment shall not be effective until the holders of at least the same
proportion in aggregate stated liquidation amount of the Trust Securities shall
have consented to such modification or amendment. The Indenture also contains
provisions permitting the holders of a majority in aggregate principal amount of
the Securities at the time outstanding, on behalf of all of the holders of the
Securities, prior to any declaration accelerating the maturity of the
Securities, to waive any past Default or Event of Default and its consequences,
except (i) a Default in the payment of the principal of or Interest on any of
the Securities or (ii) a Default in respect of any covenant or provision under
which the Indenture cannot be modified or amended without the consent of each
holder of Securities then

                                      A-11
<PAGE>

outstanding. Any such consent or waiver by the holder of this Security (unless
revoked as provided in the Indenture) shall be conclusive and binding upon such
Holder and upon all future holders and owners of this Security and of any
Security issued in exchange herefor or in place hereof (whether by registration
of transfer or otherwise), irrespective of whether or not any notation of such
consent or waiver is made upon this Security.

      7. No Impairment. No reference herein to the Indenture and no provision of
this Security or of the Indenture shall alter or impair the obligation of the
Corporation, which is absolute and unconditional, to pay the principal of and
Interest on this Security at the time and place and at the rate and in the money
herein prescribed.

      8. [Reserved]

      9. Limitation on Dividends. Subject to the exceptions set forth in Section
3.07, the Corporation will be precluded from engaging in the transaction set
forth in Section 3.07 of the Indenture, if at the time of such transaction (1)
an event has occurred with the giving of notice or the lapse of time, or both,
would constitute an Event of Default and the Corporation has not taken
reasonable steps to cure the event (provided, however, in the event of a Event
of Default under Section 5.01(d), the Corporation shall be entitled to declare
and pay dividends on its Common Stock, but only to the extent necessary to
preserve the Corporation's ability to qualify for taxation as a real estate
investment trust under Sections 856 through 860 of the Code (not taking into
account consent dividends pursuant to Section 565 of the Code)) or (2) the
Corporation shall be in default with respect to its payment obligations under
the Trust Securities Guarantee.

      10. Liquidation of Trust. Subject to the applicable provisions of the
Declaration, the Corporation will have the right at any time to liquidate the
Trust and cause the Securities to be distributed to the holders of the Trust
Securities in liquidation of the Trust.

      11. Denominations, Transfer and Exchange. The Securities are issuable only
in registered form without coupons in minimum denominations of $1,000.00 and any
integral multiple thereof. As provided in the Indenture and subject to the

transfer at the office or agency of the Corporation accompanied by a written
instrument or instruments of transfer in form satisfactory to the Corporation or
the Debenture Trustee duly executed by the holder hereof or his attorney duly
authorized in writing, and thereupon one or more new Securities of authorized
denominations and for the same aggregate principal amount and series will be
issued to the designated transferee or transferees. No service charge will be
made for any such registration of transfer, but the Corporation may require
payment of a sum sufficient to cover any tax or other governmental charge
payable in relation thereto.

      12. Persons Deemed Owners. Prior to due presentment for registration of
