interest or other payment in respect of any such delay), with the same force and effect as if made on such date. In the event that payment of the Redemption Price in respect of any Trust Securities called for redemption is improperly withheld or
refused and not paid either by the Trust or by the Depositor pursuant to the Guarantee, Distributions on such Trust Securities will continue to accrue, at the then applicable rate, from the Redemption Date originally established by the Trust for
such Trust Securities to the date such Redemption Price is actually paid, in which case the actual payment date will be the date fixed for redemption for purposes of calculating the Redemption Price. 
  
 (e) Payment of the Redemption Price on the Trust Securities shall be made to
the recordholders thereof as they appear on the Securities Register for the Trust Securities. 
  
 (f) Subject to Section 4.3(a), if less than all the Outstanding Trust Securities are to be redeemed on a Redemption Date, then the aggregate Redemption Price of Trust Securities to be redeemed shall be allocated on a
pro rata basis (based on Liquidation Amounts) among the Common Securities and the Preferred Securities. The particular Preferred Securities to be redeemed shall be selected on a pro rata basis (based upon Liquidation Amounts) not more than 60 days
prior to the Redemption Date by the Property Trustee from the Outstanding Preferred Securities not previously called for redemption, by such method (including, without limitation, by lot) as the Property Trustee shall deem fair and appropriate and
which may provide for the selection for redemption of portions (equal to $25 or an integral multiple of $25 in excess thereof) of the Liquidation Amount of Preferred Securities of a denomination larger than $25. The Property Trustee shall promptly
notify the Security Registrar in writing of the Preferred Securities selected for redemption and, in the case of any Preferred Securities selected for partial redemption, the Liquidation Amount thereof to be redeemed. For all purposes of this Trust
Agreement, unless the context otherwise requires, all provisions relating to the redemption of Preferred Securities shall relate, in the case of any Preferred Securities redeemed or to be redeemed only in part, to the portion of the Liquidation
Amount of Preferred Securities that has been or is to be redeemed. 
  
 16 

 Section 4.3. Subordination of Common Securities. 
  
 (a) Payment of Distributions (including Additional Amounts, if applicable)
on, and the Redemption Price of the Trust-Securities, as applicable, shall be made, subject to Section 4.2(f), pro rata among the Common Securities and the Preferred Securities based on the Liquidation Amount of the Trust Securities;
provided, however, that if on any Distribution Date or Redemption Date any Event of Default resulting from a Debenture Event of Default shall have occurred and is continuing, no payment of any distribution (including Additional
Amounts, if applicable) on, or Redemption Price of, any Common Security, and no other payment on account of the redemption, liquidation or other acquisition of Common Securities, shall be made unless payment in full in cash of all accumulated and
unpaid Distributions (including Additional Amounts, if applicable) on all Outstanding Preferred Securities for all Distribution periods terminating on or prior thereto, or in the case of payment of the Redemption Price, the full amount of such
Redemption Price on all Outstanding Preferred Securities then called for redemption, shall have been made or provided for, and all funds immediately available to the Property Trustee shall first be applied to the payment in full in cash of all
Distributions (including Additional Amounts, if applicable) on, or the Redemption Price of, Preferred Securities then due and payable. 
  
 (b) In the case of the occurrence of any Event of Default resulting from any Debenture Event of Default, the Holder of Common Securities will be deemed to
have waived any right to act with respect to any such Event of Default under this Trust Agreement until the effect of all such Events of Default with respect to the Preferred Securities have been cured, waived or otherwise eliminated. Until any such
Event of Default under this Trust Agreement with respect to the Preferred Securities has been so cured, waived or otherwise eliminated, the Property Trustee shall act solely on behalf of the Holders of the Preferred Securities and not 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. 
  
 Section 4.4. Payment Procedures. 
  
 Payments of Distributions (including Additional Amounts, if applicable) in respect of the Preferred Securities shall be made by check mailed to the
address of the Person entitled thereto as such address shall appear on the Securities Register or, if the Preferred Securities are held by a Clearing Agency, such Distributions shall be made to the Clearing Agency in immediately available funds,
which shall credit the relevant Persons’ accounts at such Clearing Agency on the applicable Distribution Dates. Payments in respect of the Common Securities shall be made in such manner as shall be mutually agreed between the Property Trustee
and the Common Securityholder. 
  
 Section 4.5. Tax Returns and
Reports. 
  
 The Administrative Trustees shall
prepare (or cause to be prepared), at the Depositor’s expense, and file all United States federal, state and local tax and information returns and reports required to be filed by or in respect of the Trust. In this regard, the Administrative
Trustees shall (a) prepare and file (or cause to be prepared and filed) the appropriate Internal Revenue Service form required to be filed in respect of the Trust in each taxable year of the Trust and (b) prepare and furnish (or cause to be prepared
and furnished) to each Securityholder the appropriate Internal Revenue Service form required to be provided on such form. The Administrative Trustees shall provide the Depositor and the Property Trustee with a copy of all such returns and reports
promptly after such filing or furnishing. The Trustees shall comply with United States federal withholding and backup withholding tax laws and information reporting requirements with respect to any payments to Securityholders under the Trust
Securities. 
  
 17 

 Section 4.6. Payment of Taxes, Duties, Etc. of the Trust. 
  
 Upon receipt under the Debentures of Additional Sums, the Property Trustee
shall promptly pay any taxes, duties or governmental charges of whatsoever nature (other than withholding taxes) imposed on the Trust by the United States or any other taxing authority. 
  
 Section 4.7. Payments under Indenture or Pursuant to Direct Actions. 
  
 Any amount payable hereunder to any Holder of Preferred Securities shall be
reduced by the amount of any corresponding payment that such Holder (and any Owner with respect thereto) has directly received pursuant to Section 5.8 of the Indenture or Section 5.14 of this Trust Agreement. 
  
 ARTICLE V. 
  
 TRUST SECURITIES CERTIFICATES 
  
 Section 5.1. Initial Ownership. 
  
 Upon the formation of the Trust and the contribution by the Depositor
pursuant to Section 2.3 and until the issuance of the Trust Securities, and at any time during which no Trust Securities are outstanding, the Depositor shall be the sole beneficial owner of the Trust. 
  
 Section 5.2. The Trust Securities Certificates. 
  
 The Preferred Securities Certificates shall be issued in minimum
denominations of $25 Liquidation Amount and integral multiples of $25 in excess thereof, and the Common Securities Certificates shall be issued in denominations of $25 Liquidation Amount and integral multiples thereof. The Trust Securities
Certificates shall be executed on behalf of the Trust by manual signature of at least one Administrative Trustee. Trust Securities Certificates bearing the manual signatures of individuals who were, at the time when such signatures shall have been
affixed, authorized to sign on behalf of the Trust, shall be validly issued and entitled to the benefits of this Trust Agreement, notwithstanding that such individuals or any of them shall have ceased to be so authorized prior to the delivery of
such Trust Securities Certificates or did not hold such offices at the date of delivery of such Trust Securities Certificates. A transferee of a Trust Securities Certificate shall become a Securityholder, and shall be entitled to the rights and
subject to the obligations of a Securityholder hereunder, upon due registration of such Trust Securities Certificate in such transferee’s name pursuant to Sections 5.4, 5.11 and 5.13. 
  
 Section 5.3. Execution and Delivery of Trust Securities Certificates.

  
 On the Closing Date, the Administrative Trustees
shall cause Trust Securities Certificates, in an aggregate Liquidation Amount as provided in Section 2.4 and Section 2.5, to be executed on behalf of the Trust and delivered to or upon the written order of the Depositor, signed by its chief
executive officer, its president, any executive vice president or any vice president, treasurer or assistant treasurer or controller without further corporate action by the Depositor, in authorized denominations. 
  
 Section 5.4. Registration of Transfer and Exchange of Preferred Securities
Certificates. 
  
 (a) The Depositor shall keep or
cause to be kept, at the office or agency maintained pursuant to Section 5.8, a register or registers for the purpose of registering Trust Securities Certificates and transfers and exchanges of Preferred Securities Certificates (the
“Securities Register”) in which, the registrar designated by the Depositor (the “Securities Registrar”), subject 
  

18 

 to such reasonable regulations as it may prescribe, shall provide for the registration of Preferred Securities
Certificates and Common Securities Certificates (subject to Section 5.10 in the case of the Common Securities Certificates) and registration of transfers and exchanges of Preferred Securities Certificates as herein provided. The Property Trustee
shall be the initial Securities Registrar. 
  
 (b) Upon surrender
for registration of transfer of any Preferred Securities Certificate at the office or agency maintained pursuant to Section 5.8, the Administrative Trustees or any one of them shall execute and deliver, in the name of the designated transferee or
transferees, one or more new Preferred Securities Certificates in authorized denominations of a like aggregate Liquidation Amount dated the date of execution by such Administrative Trustee or Trustees. 
  
 (c) The Securities Registrar shall not be required to register the transfer
of any Preferred Securities that have been called for redemption. At the option of a Holder, Preferred Securities Certificates may be exchanged for other Preferred Securities Certificates in authorized denominations of the same class and of a like
aggregate Liquidation Amount upon surrender of the Preferred Securities Certificates to be exchanged at the office or agency maintained pursuant to Section 5.8. 
  

(d) Every Preferred Securities Certificate presented or surrendered for registration of transfer or exchange shall be accompanied by a written
instrument of transfer in form satisfactory to an Administrative Trustee and the Securities Registrar duly executed by the Holder or his attorney duly authorized in writing. Each Preferred Securities Certificate surrendered for registration of
transfer or exchange shall be canceled and subsequently disposed of by an Administrative Trustee in accordance with such Person’s customary practice. The Trust shall not be required to (i) issue, register the transfer of, or exchange any
Preferred Securities during a period beginning at the opening of business 15 calendar days before the date of mailing of a notice of redemption of any Preferred Securities called for redemption and ending at the close business on the day of such
mailing or (ii) register the transfer of or exchange any Preferred Securities so selected for redemption, in whole or in part, except the unredeemed portion of any such Preferred Securities being redeemed in part. 
  
 (e) No service charge shall be made for any registration of transfer or
exchange of Preferred Securities Certificates, but the Securities Registrar may require payment of a sum sufficient to cover any tax or governmental charge that may be imposed in connection with any transfer or exchange of Preferred Securities
Certificates. 
  
 Section 5.5. Mutilated, Destroyed, Lost or Stolen Trust
Securities Certificates. 
  
 In the event that:

  
 (i) any mutilated Trust Securities Certificate shall be
surrendered to the Securities Registrar, or if the Securities Registrar shall receive evidence to its satisfaction of the destruction, loss or theft of any Trust Securities Certificate and 
  
 (ii) there shall be delivered to the Securities Registrar and the
Administrative Trustees such security or indemnity as may be required by them to save each of them harmless, 
  
 then in the absence of notice that such Trust Securities Certificate shall have been acquired by a bona fide purchaser, the Administrative Trustees, or any one of them, on behalf of the Trust shall execute and make
available for delivery, in exchange for or in lieu of any such mutilated, destroyed, lost or stolen Trust Securities Certificate, a new Trust Securities Certificate of like class, tenor and denomination. In connection with the issuance of any new
Trust Securities Certificate under this Section, the Administrative Trustees or the Securities Registrar may require the payment of a sum sufficient to cover any tax or other governmental charge that may be 
  
 19 

 imposed in connection therewith. Any duplicate Trust Securities Certificate issued pursuant to this Section shall
constitute conclusive evidence of an undivided beneficial interest in the assets of the Trust, as if originally issued, whether or not the lost, stolen or destroyed Trust Securities Certificate shall be found at any time. 
  
 Section 5.6. Persons Deemed Securityholders. 
  
 The Trustees or the Securities Registrar shall treat the Person in whose
name any Trust Securities Certificate shall be registered in the Securities Register as the owner of such Trust Securities Certificate for the purpose of receiving Distributions and for all other purposes whatsoever, and neither the Trustees nor the
Securities Registrar shall be bound by any notice to the contrary. 
  
 Section 5.7. Access to List of Securityholders’ Names and Addresses. 
  
 At any time when the Property Trustee is not also acting as the Securities Registrar, the Administrative Trustees or the Depositor shall furnish or cause
to be furnished to the Property Trustee: 
  
 (i) semi-annually on
or before January 1 and July 1 in each year, a list, in such form as the Property Trustee may reasonably require, of the names and addresses of the Securityholders as of the most recent Record Date, and 
  
 (ii) promptly after receipt by any Administrative Trustee or the Depositor
of a request therefor from the Property Trustee, such other information as the Property Trustee may reasonably require in order to enable the Property Trustee to discharge its obligations under this Trust Agreement, 
  
 in each case to the extent such information is in the possession or control of the
Administrative Trustees or the Depositor and is not identical to a previously supplied list or has not otherwise been received by the Property Trustee in its capacity as Securities Registrar. The rights of Securityholders to communicate with other
Securityholders with respect to their rights under this Trust Agreement or under the Trust Securities, and the corresponding rights of the Trustee shall be as provided in the Trust Indenture Act. Each Securityholder, by receiving and holding a Trust
Securities Certificate, and each Owner shall be deemed to have agreed not to hold the Depositor, the Property Trustee or the Administrative Trustees accountable by reason of the disclosure of its name and address, regardless of the source from which
such information was derived. 
  
 Section 5.8. Maintenance of
Office or Agency. 
  
 The Administrative Trustees
shall maintain an office or offices or agency or agencies where Preferred Securities Certificates may be surrendered for registration of transfer or exchange and where notices and demands to or upon the Trustees in respect of the Trust Securities
Certificates may be served. The Administrative Trustees initially designate the principal corporate trust office of the Property Trustee, The Bank of New York, 101 Barclay Street, Floor 8 West, New York, New York 10286, Attention: Corporate Trust
Administration, as the principal corporate trust office for such purposes. The Administrative Trustees shall give prompt written notice to the Depositor and to the Securityholders of any change in the location of the Securities Register or any such
office or agency. 
  
 Section 5.9. Appointment of Paying
Agent. 
  
 The Paying Agent shall make Distributions
to Securityholders from the Payment Account and shall report the amounts of such Distributions to the Property Trustee and the Administrative Trustees. Any Paying Agent shall have the revocable power to withdraw funds from the Payment Account for
the purpose of making the Distributions referred to above. The Administrative 
  
 20 

 Trustees may revoke such power and remove the Paying Agent if such Trustees determine in their sole discretion that the
Paying Agent shall have failed to perform its obligations under this Trust Agreement in any material respect. The Paying Agent shall initially be the Property Trustee, and any co-paying agent chosen by the Property Trustee, and acceptable to the
Administrative Trustees and the Depositor. Any Person acting as Paying Agent shall be permitted to resign as Paying Agent upon 30 days’ written notice to the Administrative Trustees, the Property Trustee and the Depositor. In the event that the
Property Trustee shall no longer be the Paying Agent or a successor Paying Agent shall resign or its authority to act be revoked, the Administrative Trustees shall appoint a successor that is acceptable to the Property Trustee and the Depositor to
act as Paying Agent (which shall be a bank or trust company). The Administrative Trustees shall cause such successor Paying Agent or any additional Paying Agent appointed by the Administrative Trustees to execute and deliver to the Trustees an
instrument in which such successor Paying Agent or additional Paying Agent shall agree with the Trustees that as Paying Agent, such successor Paying Agent or additional Paying Agent will hold all sums, if any, held by it for payment to the
Securityholders in trust for the benefit of the Securityholders entitled thereto until such sums shall be paid to such Securityholders. The Paying Agent shall return all unclaimed funds to the Property Trustee and upon removal of a Paying Agent,
such Paying Agent shall also return all funds in its possession to the Property Trustee. The provisions of Sections 8.1, 8.3 and 8.6 herein shall apply to the Property Trustee also in its role as Paying Agent, for so long as the Property Trustee
shall act as Paying Agent and, to the extent applicable, to any other paying agent appointed hereunder. Any reference in this Trust Agreement to the Paying Agent shall include any co-paying agent unless the context requires otherwise. 
  
 Section 5.10. Ownership of Common Securities by Depositor.

  
 At the Closing Date, the Depositor shall acquire and
retain beneficial and record ownership of the Common Securities. To the fullest extent permitted by law, other than a transfer in connection with a consolidation or merger of the Depositor into another Person, or any conveyance, transfer or lease by
the Depositor of its properties and assets substantially as an entirety to any Person, pursuant to Section 8.l of the Indenture, any attempted transfer of the Common Securities shall be void. The Administrative Trustees shall cause each Common
Securities Certificate issued to the Depositor to contain a legend stating “THIS CERTIFICATE IS NOT TRANSFERABLE”. 
  
 Section 5.11. Book Entry Preferred Securities Certificates; Common Securities Certificate. 
  
 (a) The Preferred Securities Certificates, upon original issuance, will be
issued in the form of a typewritten Preferred Securities Certificate or Certificates representing Book-Entry Preferred Securities Certificates, to be delivered to The Depository Trust Company, the initial Clearing Agency, by, or on behalf of, the
Trust. Such Preferred Securities Certificate or Certificates shall initially be registered on the Securities Register in the name of Cede & Co., the nominee of the initial Clearing Agency, and no Owner will receive a Definitive Preferred
Securities Certificate representing such Owner’s interest in such Preferred Securities, except as provided in Section 5.13. Unless and until Definitive Preferred Securities Certificates have been issued to Owners pursuant to Section 5.13:

  
 (i) the provisions of this Section 5.11(a) shall be in full
force and effect; 
  
 (ii) the Securities Registrar, the Paying
Agent and the Trustees shall be entitled to deal with the Clearing Agency for all purposes of this Trust Agreement relating to the Book-Entry Preferred Securities Certificates (including the payment of the Liquidation Amount of and Distributions on
the Preferred Securities evidenced by Book-Entry Preferred Securities Certificates) and shall have no obligations to the Owners thereof; 
  
 21 

 (iii) to the extent that the provisions of this Section 5.11 conflict with any other provisions of this
Trust Agreement, the provisions of this Section 5.11 shall control; and 
  
 (iv) the rights of the Owners of the Book-Entry Preferred Securities Certificates shall be exercised only through the Clearing Agency and shall be limited to those established by law and agreements between such Owners
and the Clearing Agency and/or the Clearing Agency Participants. Pursuant to the Certificate Depository Agreement, unless and until Definitive Preferred Securities Certificates are issued pursuant to Section 5.13, the initial Clearing Agency will
make book-entry transfers among the Clearing Agency Participants and receive and transmit payments on the Preferred Securities to such Clearing Agency Participants. Any Clearing Agency designated pursuant hereto will not be deemed an agent of the
Trustee for any purpose. 
  
 (b) A single Common Securities
Certificate representing the Common Securities shall be issued to the Depositor in the form of a definitive Common Securities Certificate. 
  
 (c) The Property Trustee shall have no obligation or duty to monitor, determine or inquire as to compliance with any restrictions on transfer imposed
under this Trust Agreement or under applicable law with respect to any transfer of any interest in the Preferred Securities (including any transfers between or among Clearing Agency Participants or Owners) other than to inquire 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 the Trust Agreement, and to examine the same to determine substantial compliance as to form with the express
requirements hereof. 
  
 Section 5.12. Notices to Clearing
Agency. 
  
 To the extent that a notice or other
communication to the Owners is required under this Trust Agreement, unless and until Definitive Preferred Securities Certificates shall have been issued to Owners pursuant to Section 5.13, the Trustees shall give all such notices and communications
specified herein to be given to Owners to the Clearing Agency, and shall have no obligations to the Owners. 
  
 Section 5.13. Definitive Preferred Securities Certificates. 
  
 In the event that: 
  
 (i) the Depositor advises the Trustees in writing that the Clearing Agency is no longer willing or able to properly discharge its responsibilities with
respect to the Preferred Securities Certificates, and the Depositor is unable to locate a qualified successor, or if at any time the Person then acting as Clearing Agency ceases to be registered under the Exchange Act at a time when such Person is
required to be so registered, or 
  
 (ii) the Depositor at its
option advises the Trustees in writing that it elects to terminate the book-entry system through the Clearing Agency, 
  
 then the Property Trustee shall notify the Clearing Agency and the Clearing Agency shall notify all Owners of Preferred Securities Certificates and the other Trustees of
the occurrence of any such event and of the availability of the Definitive Preferred Securities Certificates to Owners of such class or classes, as applicable, requesting the same. Upon surrender to the Property Trustee of the typewritten Preferred
Securities Certificate or Certificates representing the Book Entry Preferred Securities Certificates by the Clearing Agency, accompanied by registration instructions, the Administrative Trustees, or any one of them, shall execute the Definitive
Preferred Securities Certificates in accordance with the instructions of the Clearing Agency. Neither the Securities Registrar nor the Trustees shall be liable for any delay in delivery of such instructions and may conclusively rely on, and shall be
protected in relying on, such instructions. 
  
 22 

 Upon the issuance of Definitive Preferred Securities Certificates, the Trustees shall recognize the Holders of the
Definitive Preferred Securities Certificates as Securityholders. The Definitive Preferred Securities Certificates shall be engraved and executed in accordance with the applicable rules of the Nasdaq National Market or such other national exchange or
over-the-counter market on which the Preferred Securities are then listed for trading. 
  
 Section 5.14. Rights of Securityholders. 
  
 (a) The legal title to the Trust Property is vested exclusively in the Property Trustee (in its capacity as such) in accordance with Section 2.9, and the Securityholders shall not have any right or title therein other
than the undivided beneficial interest in the assets of the Trust conferred by their Trust Securities and they shall have no right to call for any partition or division of property, profits or rights of the Trust except as described below. The Trust
Securities shall be personal property giving only the rights specifically set forth therein and in this Trust Agreement. The Trust Securities shall have no preemptive or similar rights and when issued and delivered to Securityholders against payment
of the purchase price therefor will be fully paid and nonassessable by the Trust. The Holders of the Trust Securities, in their capacities as such, 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. 
  
 (b) For so long as any Preferred Securities remain Outstanding, if, upon a Debenture Event of Default, the Debenture Trustee fails or the holders of not less than 25% in principal amount of the outstanding Debentures
fail to declare the principal of all of the Debentures to be immediately due and payable, the Holders of at least 25% in Liquidation Amount of the Preferred Securities then Outstanding shall have such right by a notice in writing to the Depositor
and the Debenture Trustee; and upon any such declaration such principal amount of and the accrued interest on all of the Debentures shall become immediately due and payable, provided that the payment of principal and interest on
such Debentures shall remain subordinated to the extent provided in the Indenture. At any time after such a declaration of acceleration with respect to the Debentures has been made and before a judgment or decree for payment of the money due has
been obtained by the Debenture Trustee as in the Indenture provided, the Holders of a majority in Liquidation Amount of the Preferred Securities, by written notice to the Property Trustee, the Depositor and the Debenture Trustee, may rescind and
annul such declaration and its consequences if: 
  
 (i) the
Depositor has paid or deposited with the Debenture Trustee a sum sufficient to pay 
  

	 	(A)	all overdue installments of interest (including any Additional Interest (as defined in the Indenture)) on all of the Debentures, 

  

	 	(B)	the principal of (and premium, if any, on) any Debentures which have become due otherwise than by such declaration of acceleration and interest thereon at the rate borne by the
Debentures, and 

  

	 	(C)	all sums paid or advanced by the Debenture Trustee under the Indenture and the reasonable compensation, expenses, disbursements and advances of the Debenture Trustee and the
Property Trustee, their agents and counsel, and 

  
 (ii) all Events of Default with respect to the Debentures, other than the non-payment of the principal of the Debentures which has become due solely by such acceleration, have been cured or waived as provided in Section 5.13 of the
Indenture. 
  
 The Holders of a majority in aggregate Liquidation Amount of the
Preferred Securities may, on behalf of the Holders of all the Preferred Securities, waive any past default under the Indenture, except a default in the payment of principal or interest (unless such default has been cured and a 
  
 23 

 sum sufficient to pay all matured installments of interest and principal due otherwise than by acceleration has been
deposited with the Debenture Trustee) or a default in respect of a covenant or provision which under the Indenture cannot be modified or amended without the consent of the holder of each outstanding Debenture. No such rescission shall affect any
subsequent default or impair any right consequent thereon. Upon receipt by the Property Trustee of written notice declaring such an acceleration, or rescission and annulment thereof, by Holders of the Preferred Securities, all or part of which is
represented by Book-Entry Preferred Securities Certificates, a record date shall be established for determining Holders of Outstanding Preferred Securities entitled to join in such notice, which record date shall be at the close of business on the
day the Property Trustee receives such notice. The Holders on such record date, or their duly designated proxies, and only such Persons, shall be entitled to join in such notice, whether or not such Holders remain Holders after such record date;
provided, that, unless such declaration of acceleration, or rescission and annulment, as the case may be, shall have become effective by virtue of the requisite percentage having joined in such notice prior to the day which is 90 days
after such record date, such notice of declaration of acceleration, or rescission and annulment, as the case may be, shall automatically and without further action by any Holder be canceled and of no further effect. Nothing in this paragraph shall
prevent a Holder, or a proxy of a Holder, from giving, after expiration of such 90-day period, a new written notice of declaration of acceleration, or rescission and annulment thereof, as the case may be, that is identical to a written notice which
has been canceled pursuant to the proviso to the preceding sentence, in which event a new record date shall be established pursuant to the provisions of this Section 5.14(b). 
  
 (c) For so long as any Preferred Securities remain Outstanding, to the fullest extent permitted by law and subject to the
terms of this Trust Agreement and the Indenture, upon a Debenture Event of Default specified in Section 5.1(a) or 5.1(b) of the Indenture, any Holder of Preferred Securities shall have the right to institute a proceeding directly against the
Depositor, pursuant to Section 5.8 of the Indenture, for enforcement of payment to such Holder of the principal amount of (premium, if any) and (subject to Section 3.7 of the Indenture) interest (including any Additional Interest (as defined on the
Indenture)) on Debentures having a principal amount equal to the Liquidation Amount of the Preferred Securities of such Holder (a “Direct Action”). Except as set forth in Section 5.14(b) and this Section 5.14(c), the Holders
of Preferred Securities shall have no right to exercise directly any right or remedy available to the holders of, or in respect of, the Debentures. 
  
 ARTICLE VI. 
  
 ACTS OF SECURITYHOLDERS; MEETINGS, VOTING 
  
 Section 6.1. Limitations on Voting Rights. 
  
 (a) Except as provided in this Section, in Sections 5.14, 8.10 and 10.2 and in the Indenture and as otherwise required by law, no Holder of Preferred
Securities shall have any right to vote or in any manner otherwise control the administration, operation and management of the Trust or the obligations of the parties hereto, nor shall anything herein set forth, or contained in the terms of the
Trust Securities Certificates, be construed so as to constitute the Securityholders from time to time as partners or members of an association. 
  
 (b) 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 execute any trust or power conferred on the Property Trustee with respect to such Debentures, (ii) waive any past default which is waivable under Section 5.13 of the Indenture, (iii) exercise any
right to rescind or annul a declaration that the principal of all the Debentures shall be due and payable or (iv) consent to any amendment, modification or termination of the Indenture or the Debentures, where such consent shall be required,
without, in each case, obtaining the prior approval of the Holders of at least a majority in Liquidation Amount of all Outstanding Preferred Securities, provided, however, that where a consent under the 
  
 24 

 Indenture would require the consent of each Holder of Debentures affected thereby, no such consent shall be given by the
Property Trustee without the prior written consent of each Holder of Preferred Securities. The Trustees shall not revoke any action previously authorized or approved by a vote of the Holders of Preferred Securities, except by a subsequent vote of
the Holders of Preferred Securities. The Property Trustee shall notify all Holders of the Preferred Securities of any notice of default received from the Debenture Trustee with respect to the Debentures. In addition to obtaining the foregoing
approvals of the Holders of the Preferred Securities, prior to taking any of the foregoing actions, the Trustees shall, at the expense of the Depositor, obtain an Opinion of Counsel experienced in such matters to the effect that such action shall
not cause the Trust to fail to be classified as a grantor trust for United States federal income tax purposes. 
  
 (c) If any proposed amendment to the Trust Agreement provides for, or the Trustees otherwise propose to effect, (i) any action that would adversely affect
in any material respect the powers, preferences or special rights of the Preferred Securities, whether by way of amendment to the Trust Agreement or otherwise, or (ii) the dissolution, winding-up or termination of the Trust, other than pursuant to
the terms of this Trust Agreement, then the Holders of Outstanding Preferred Securities as a class will be entitled to vote on such amendment or proposal and such amendment or proposal shall not be effective except with the approval of the Holders
of at least a majority in Liquidation Amount of the Outstanding Preferred Securities. Notwithstanding any other provision of this Trust Agreement, no amendment to this Trust Agreement may be made if, as a result of such amendment, it would cause the
Trust to fail to be classified as a grantor trust for United States federal income tax purposes. 
  
 Section 6.2. Notice of Meetings. 
  
 Notice of all meetings of the Preferred Securityholders, stating the time, place and purpose of the meeting, shall be given by the Property Trustee pursuant to Section 10.9 to each Preferred Securityholder of record,
at his, her or its registered address, at least 15 days and not more than 90 days before the meeting. At any such meeting, any business properly before the meeting may be so considered whether or not stated in the notice of the meeting. Any
adjourned meeting may be held as adjourned without further notice. 
  
 Section 6.3. Meetings of Preferred Securityholders. 
  
 (a) No annual meeting of Securityholders is required to be held. The Administrative Trustees, however, shall call a meeting of Preferred Securityholders to vote on any matter upon the written request of Holders of
record of 25% of the Outstanding Preferred Securities (based upon their Liquidation Amount) and the Administrative Trustees or the Property Trustee may, at any time, call a meeting of Preferred Securityholders to vote on any matters as to which
Preferred Securityholders are entitled to vote. 
  
 (b) Holders of
record of 50% of the Outstanding Preferred Securities (based upon their Liquidation Amount), present in person or by proxy, shall constitute a quorum at any meeting of Securityholders. If a quorum is present at a meeting, an affirmative vote by the
Preferred Securityholders of record present, in person or by proxy, holding more than a majority of the Preferred Securities (based upon their Liquidation Amount) held by the Preferred Securityholders of record present, either in person or by proxy,
at such meeting shall constitute the action of the Preferred Securityholders, unless this Trust Agreement requires a greater number of affirmative votes. 
  
 Section 6.4. Voting Rights. 
  
 Securityholders shall be entitled to one vote for each $25 of Liquidation Amount represented by their Trust Securities in respect of any matter as to
which such Securityholders are entitled to vote. 
  
 25 

 Section 6.5. Proxies, etc. 
  
 At any meeting of Securityholders, any Securityholder entitled to vote thereat may vote by proxy, provided
that no proxy shall be voted at any meeting unless it shall have been placed on file with the Administrative Trustees, or with such other officer or agent of the Trust as the Administrative Trustees may direct, for verification prior to the
time at which such vote shall be taken. Pursuant to a resolution of the Property Trustee, proxies may be solicited in the name of the Property Trustee or one or more officers of the Property Trustee. Only Securityholders of record shall be entitled
to vote. When Trust Securities are held jointly by several Persons, any one of them may vote at any meeting in person or by proxy in respect of such Trust Securities, but if more than one of them shall be present at such meeting in person or by
proxy, and such joint owners or their proxies so present disagree as to any vote to be cast, such vote shall not be received in respect of such Trust Securities. A proxy purporting to be executed by or on behalf of a Securityholder shall be deemed
valid unless challenged at or prior to its exercise, and the burden of proving invalidity shall rest on the challenger. No proxy shall be valid more than three years after its date of execution. 
  
 Section 6.6. Securityholder Action by Written Consent.

  
 Any action which may be taken by Securityholders at a
meeting may be taken without a meeting if Securityholders holding a majority of all Outstanding Trust Securities (based upon their aggregate Liquidation Amount) entitled to vote in respect of such action (or such larger proportion thereof as shall
be required by any express provision of this Trust Agreement) shall consent to the action in writing (based upon their aggregate Liquidation Amount). 
  
 Section 6.7. Record Date for Voting and Other Purposes. 
  
 For the purposes of determining the Securityholders who are entitled to notice of and to vote at any meeting or by written
consent, or to participate in any Distribution on the Trust Securities in respect of which a record date is not otherwise provided for in this Trust Agreement, or for the purpose of any other action, the Administrative Trustees may from time to time
fix a date, not more than 90 days prior to the date of any meeting of Securityholders or the payment of a Distribution or other action, as the case may be, as a record date for the determination of the identity of the Securityholders of record for
such purposes. 
  
 Section 6.8. Acts of Securityholders.

  
 (a) Any request, demand, authorization, direction,
notice, consent, waiver or other action provided or permitted by this Trust Agreement to be given, made or taken by Securityholders or Owners may be embodied in and evidenced by one or more instruments of substantially similar tenor signed by such
Securityholders or Owners in person or by an agent duly appointed in writing; and, except as otherwise expressly provided herein, such action shall become effective when such instrument or instruments are delivered to an Administrative Trustee. Such
instrument or instruments (and the action embodied therein and evidenced thereby) are herein sometimes referred to as the “Act” of the Securityholders or Owners signing such instrument or instruments. Proof of execution of any such
instrument or of a writing appointing any such agent shall be sufficient for any purpose of this Trust Agreement and (subject to Section 8.1) conclusive in favor of the Trustees, if made in the manner provided in this Section. 
  
 (b) The fact and date of the execution by any Person of any such instrument
or writing may be proved by the affidavit of a witness of such execution or by a certificate of a notary public or other officer authorized by law to take acknowledgments of deeds, certifying that the individual signing such instrument or writing
acknowledged to him the execution thereof. Where such execution is by a signer acting in a capacity other than his individual capacity, such certificate or affidavit shall also constitute sufficient proof of his authority. The fact and date of the

  
 26 

 execution of any such instrument or writing, or the authority of the Person executing the same, may also be proved in any
other manner which any Trustee receiving the same deems sufficient. 
  
 (c) The ownership of Preferred Securities shall be proved by the Securities Register. 
  
 (d) Any request, demand, authorization, direction, notice, consent, waiver or other Act of the Securityholder of any Trust Security shall bind every future Securityholder of the same Trust Security and the
Securityholder of every Trust Security issued upon the registration of transfer thereof or in exchange therefor or in lieu thereof in respect of anything done, omitted or suffered to be done by the Trustees or the Trust in reliance thereon, whether
or not notation of such action is made upon such Trust Security. 
  
 (e) Without limiting the foregoing, a Securityholder entitled hereunder to take any action hereunder with regard to any particular Trust Security may do so with regard to all or any part of the Liquidation Amount of such Trust Security or
by one or more duly appointed agents each of which may do so pursuant to such appointment with regard to all or any part of such Liquidation Amount. 
  
 (f) A Securityholder may institute a legal proceeding directly against the Depositor under the Guarantee to enforce its rights under the Guarantee without
first instituting a legal proceeding against the Guarantee Trustee (as defined in the Guarantee), the Trust or any Person. 
  
 Section 6.9. Inspection of Records. 
  
 Upon reasonable notice to the Administrative Trustees and the Property Trustee, the records of the Trust shall be open to inspection by Securityholders
during normal business hours for any purpose reasonably related to such Securityholder’s interest as a Securityholder.

 ARTICLE VIII. 
  
 THE TRUSTEES 
  
 Section 8.1. Certain Duties and Responsibilities. 
  
 (a) The duties and responsibilities of the Trustees shall be as provided by
this Trust Agreement and, in the case of the Property Trustee, by the Trust Indenture Act. Notwithstanding the foregoing, no provision of this Trust Agreement shall require the Trustees to expend or risk their own funds or otherwise incur any
financial liability in the performance of any of their duties hereunder, or in the exercise of any of their rights or powers, unless they are afforded reasonable indemnity against such risk or liability. Whether or not therein expressly so provided,
every provision of this Trust Agreement relating to the conduct or affecting the liability of or affording protection to the Trustees shall be subject to the provisions of this Section. No Administrative Trustee or the Delaware Trustee shall be
subject to any liability under this Trust Agreement except for its own grossly negligent action, its own grossly negligent failure to act, or its own 
  
 28 

 willful misconduct. To the extent that, at law or in equity, a Trustee has duties (including fiduciary duties) and
liabilities relating thereto to the Trust or to the Securityholders, such Trustee shall not be liable to the Trust or to any Securityholder for such Trustee’s good faith reliance on the provisions of this Trust Agreement. The provisions of this
Trust Agreement, to the extent that they restrict the duties and liabilities of the Trustees otherwise existing at law or in equity, are agreed by the Depositor and the Securityholders to replace such other duties and liabilities of the Trustees.

  
 (b) All payments made by the Property Trustee or a Paying
Agent in respect of the Trust Securities shall be made only from the revenue and proceeds from the Trust Property and only to the extent that there shall be sufficient revenue or proceeds from the Trust Property to enable the Property Trustee or a
Paying Agent to make payments in accordance with the terms hereof. Each Securityholder, by its acceptance of a Trust Security, agrees that it will look solely to the revenue and proceeds from the Trust Property to the extent legally available for
distribution to it as herein provided and that the Trustees are not personally liable to it for any amount distributable in respect of any Trust Security or for any other liability in respect of any Trust Security. This Section 8.1(b) does not limit
the liability of the Trustees expressly set forth elsewhere in this Trust Agreement or, in the case of the Property Trustee, in the Trust Indenture Act. 
  
 (c) No provision of this Trust Agreement shall be construed to relieve the Property Trustee from liability for its own negligent action, its own negligent
failure to act, or its own willful misconduct, except that: 
  
 (i) the Property Trustee shall not be liable for any error of judgment made in good faith by an authorized officer of the Property Trustee, unless it shall be proved that the Property Trustee was negligent in ascertaining the pertinent
facts, 
  
 (ii) 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 the Trust Securities given in accordance with this Trust Agreement relating to the time, method and place of conducting any
proceeding for any remedy available to the Property Trustee, or exercising any trust or power conferred upon the Property Trustee under this Trust Agreement; 
  

(iii) the Property Trustee’s sole duty with respect to the custody, safe keeping and physical preservation of the Debentures and the Payment
Account shall be to deal with such Property in a similar manner as the Property Trustee deals with similar property for its own account, subject to the protections and limitations on liability afforded to the Property Trustee under this Trust
Agreement and the Trust Indenture Act; 
  
 (iv) the Property
Trustee shall not be liable for any interest on any money received by it except as it may otherwise agree with the Depositor; and money held by the Property Trustee need not be segregated from other funds held by it except in relation to the Payment
Account maintained by the Property Trustee pursuant to Section 3.1 and except to the extent otherwise required by law; and 
  
 (v) the Property Trustee shall not be responsible for monitoring the compliance by the Administrative Trustees or the Depositor with their respective
duties under this Trust Agreement, nor shall the Property Trustee be liable for the default or misconduct of the Administrative Trustees or the Depositor. 
  
 Section 8.2. Certain Notices. 
  
 (a) Within five Business Days after the occurrence of any Event of Default actually known to a Responsible Officer of the Property Trustee, the Property
Trustee shall transmit, in the 
  
 29 

 manner and to the extent provided in Section 10.9, notice of such Event of Default to the Securityholders, the
Administrative Trustees and the Depositor, unless the Event of Default shall have been cured or waived. For purposes of this Section the term “Event of Default” means any event that is, or after notice or lapse of time
or both would become, and Event of Default. 
  
 (b) The
Administrative Trustees shall transmit, to the Securityholders in the manner and to the extent provided in Section 10.9, notice of the Depositor’s election to begin or further extend an Extension Period on the Debentures (unless such election
shall have been revoked) within the time specified for transmitting such notice to the holders of the Debentures pursuant to the Indenture as originally executed. 
  
 Section 8.3. Certain Rights of Property Trustee. 
  
 Subject to the provisions of Section 8.1: 
  
 (a) the Property Trustee may conclusively rely and shall be protected in acting or refraining from acting in good faith upon
any resolution, Opinion of Counsel, certificate, written representation of a Holder or transferee, certificate of auditors or any other certificate, statement, instrument, opinion, report, notice, request, consent, order, appraisal, bond, debenture,
note, other evidence of indebtedness 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) in the event that, (i) in performing its duties under this Trust Agreement the Property Trustee is required to decide
between alternative courses of action or (ii) in construing any of the provisions of this Trust Agreement the Property Trustee finds the same ambiguous or inconsistent with any other provisions contained herein or (iii) the Property Trustee is
unsure of the application of any provision of this Trust Agreement, then, except as to any matter as to which the Preferred Securityholders are entitled to vote under the terms of this Trust Agreement, the Property Trustee shall deliver a notice to
the Depositor requesting written instructions of the Depositor as to the course of action to be taken and the Property Trustee shall take such action, or refrain from taking such action, as the Property Trustee shall be instructed in writing to
take, or to refrain from taking, by the Depositor; provided, however, that if the Property Trustee does not receive such instructions of the Depositor within ten Business Days after it has delivered such notice, or such
reasonably shorter period of time set forth in such notice (which to the extent practicable shall not be less than two Business Days), it may, but shall be under no duty to, take or refrain from taking such action not inconsistent with this Trust
Agreement as it shall deem advisable and in the best interests of the Securityholders, in which event the Property Trustee shall have no liability except for its own bad faith, negligence or willful misconduct; 
  
 (c) any direction or act of the Depositor or the Administrative Trustees
contemplated by this Trust Agreement shall be sufficiently evidenced by an Officers’ Certificate; 
  
 (d) whenever in the administration of this Trust Agreement, the Property Trustee shall deem it desirable that a matter be established before undertaking,
suffering or omitting any action hereunder, the Property Trustee (unless other evidence is herein specifically prescribed) may, in the absence of bad faith on its part, request and rely upon an Officers’ Certificate which, upon receipt of such
request, shall be promptly delivered by the Depositor or the Administrative Trustees; 
  
 (e) the Property Trustee shall have no duty to see to any recording, filing or registration of any instrument (including any financing or continuation statement or any filing under tax or securities laws) or any
rerecording, refiling or registration thereof, 
  
 (f) the
Property Trustee may consult with counsel and the advice of such counsel shall be full and complete authorization and protection in respect of any action taken, suffered or omitted by it hereunder in good faith and in reliance thereon and in
accordance with such advice, 
  
 30 

 such counsel may be counsel to the Depositor or any of its Affiliates, but not an employee thereof; the Property Trustee
shall have the right at any time to seek instructions concerning the administration of this Trust Agreement from any court of competent jurisdiction; 
  
 (g) the Property Trustee shall be under no obligation to exercise any of the rights or powers vested in it by this Trust Agreement at the request or
direction of any of the Securityholders pursuant to this Trust Agreement, unless such Securityholders shall have offered to the Property Trustee security or indemnity reasonably satisfactory to it against the costs, expenses and liabilities which
might be incurred by it in compliance with such request or direction; 
  
 (h) the Property Trustee shall not be bound to make any investigation into the facts or matters stated in any resolution, certificate, statement, instrument, opinion, report, notice, request, consent, order, approval, bond, debenture, note
or other evidence of indebtedness or other paper or document, unless requested in writing to do so by one or more Securityholders, but the Property Trustee may make such further inquiry or investigation into such facts or matters as it may see fit;

  
 (i) the Property Trustee may execute any of the trusts or
powers hereunder or perform any duties hereunder either directly or by or through its agents or attorneys, provided that the Property Trustee shall be responsible for its own negligence or recklessness with respect to selection
of any agent or attorney appointed by it hereunder; 
  
 (j)
whenever in the administration of this Trust Agreement the Property Trustee shall deem it desirable to receive instructions with respect to enforcing any remedy or right or taking any other action hereunder the Property Trustee (i) may request
instructions from the Holders of the Trust Securities which instructions may only be given by the Holders of the same proportion in Liquidation Amount of the Trust Securities as would be entitled to direct the Property Trustee under the terms of the
Trust Securities in respect of such remedy, right or action, (ii) may refrain from enforcing such remedy or right or taking such other action until such instructions are received, and (iii) shall be protected in acting in accordance with such
instructions; 
  
 (k) except as otherwise expressly provided by
this Trust Agreement, the Property Trustee shall not be under any obligation to take any action that is discretionary under the provisions of this Trust Agreement; and 
  
 (l) the Property Trustee shall not be liable for any action taken, suffered, or omitted to be taken by it in good faith and
reasonably believed by it to be authorized or within the discretion or rights or powers conferred upon it by this Trust Agreement. 
  
 (m) the Property Trustee shall not 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 a default is received by the Property Trustee at the Corporate Trust Office of the Property Trustee, and such notice references the Debentures or the Preferred Securities and the Trust
Agreement; 
  
 (n) 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; and 
  
 (o) the Property Trustee
may request that the Depositor 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 Trust Agreement, 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. 
  
 31 

 No provision of this Trust Agreement shall be deemed to impose any duty or obligation on the Property
Trustee to perform any act or acts or exercise any right, power, duty or obligation conferred or imposed on it, in any jurisdiction in which it shall be illegal, or in which the Property Trustee shall be unqualified or incompetent in accordance with
applicable law, to perform any such act or acts, or to exercise any such right, power, duty or obligation. No permissive power or authority available to the Property Trustee shall be construed to be a duty. 
  
 Section 8.4. Not Responsible for Recitals or Issuance of Securities.

  
 The recitals contained herein and in the Trust
Securities Certificates shall be taken as the statements of the Trust, and the Trustees do not assume any responsibility for their correctness. The Trustees shall not be accountable for the use or application by the Depositor of the proceeds of the
Debentures. 
  
 Section 8.5. May Hold Securities.

  
 Any Trustee or any other agent of any Trustee or the
Trust, in its individual or any other capacity, may become the owner or pledgee of Trust Securities and, except as provided in the definition of the term “Outstanding” in Article I and subject to Sections 8.8 and 8.13, may otherwise deal
with the Trust with the same rights it would have if it were not a Trustee or such other agent. 
  
 Section 8.6. Compensation; Indemnity; Fees. 
  
 The Depositor agrees: 
  
 (a) to pay to the Trustees from time to time reasonable compensation for all services rendered by them hereunder (which compensation shall not be limited
by any provision of law in regard to the compensation of a trustee of an express trust) as specified in a separate agreement between any of the Trustees and the Depositor; 
  
 (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 Trust Agreement (including the reasonable compensation and the expenses and disbursements of its agents and counsel), except any such expense,

damage, liability, penalty, expense (including taxes (other than taxes based upon the income of the Indemnified Person)) or claim of any kind or nature whatsoever incurred by such Indemnified Person by reason of the creation, operation or
dissolution of the Trust or 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 authority conferred on such
Indemnified Person by this Trust Agreement, except that no Indemnified Person shall be entitled to be indemnified in respect of any loss, damage or claim incurred by such Indemnified Person by reason of gross negligence (or ordinary negligence in
the case of the Property Trustee) or bad faith with respect to such acts or omissions. 
  
 The provisions of this Section 8.6 shall survive the termination of this Trust Agreement and the resignation or removal of such Indemnified Person. 
  
 32 

 No Trustee may claim any lien or charge on any Trust Property as a result of any amount due pursuant to
this Section 8.6. 
  
 The Depositor and any Trustee may (subject
to Section 8.8) engage in or possess an interest in other business ventures of any nature or description, independently or with others, similar or dissimilar to the business of the Trust, and the Trust and the Holders of Trust Securities shall have
no rights by virtue of this Trust Agreement in and to such independent ventures or the income or profits derived therefrom, and the pursuit of any such venture, even if competitive with the business of the Trust, shall not be deemed wrongful or
improper. Neither the Depositor, nor any 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
the Depositor or any 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 Trustee may engage or be interested in any
financial or other transaction with the Depositor or any Affiliate of the Depositor, or may act as depository for, trustee or agent for, or act on any committee or body of holders of, securities or other obligations of the Depositor or its
Affiliates. 
  
 Section 8.7. Corporate Property Trustee Required;
Eligibility of Trustees. 
  
 (a) There shall at all
times be a Property Trustee hereunder with respect to the Trust Securities. The Property Trustee shall be a Person that is eligible pursuant to the Trust Indenture Act to act as such and has a combined capital and surplus of at least $50,000,000. If
any such Person publishes reports of condition at least annually, pursuant to law or to the requirements of its supervising or examining authority, then for the purposes of this Section, 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. If at any time the Property Trustee with respect to the Trust Securities shall cease to be eligible in accordance with the provisions of
this Section, it shall resign immediately in the manner and with the effect hereinafter specified in this Article. 
  
 (b) There shall at all times be one or more Administrative Trustees hereunder with respect to the Trust Securities. Each Administrative Trustee shall be
either a natural person who is at least 21 years of age or a legal entity that shall act through one or more persons authorized to bind that entity. 
  
 (c) There shall at all times be a Delaware Trustee with respect to the Trust Securities. The Delaware Trustee shall either be (i) a natural person who is
at least 21 years of age and a resident of the State of Delaware or (ii) a legal entity with its principal place of business in the State of Delaware and that otherwise meets the requirements of applicable Delaware law that shall act through one or
more persons authorized to bind such entity. 
  
 Section 8.8.
Conflicting Interests. 
  
 If the Property Trustee
has or shall acquire a conflicting interest within the meaning of the Trust Indenture Act, the Property Trustee shall either eliminate such interest or resign, to the extent and in the manner provided by, and subject to the provisions of, the Trust
Indenture Act and this Trust Agreement. 
  
 Section 8.9.
Co-Trustees and Separate Trustee. 
  
 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 Property may at the time be located, the
Depositor and the Administrative Trustees, by agreed action of the majority of such Trustees, shall have power to appoint, and upon the written request of the Administrative Trustees, the Depositor shall for such purpose join with the Administrative
Trustees in the execution, delivery, and performance of all 
  
 33

 instruments and agreements necessary or proper to appoint, one or more Persons approved by the Property Trustee either to
act as co-trustee, jointly with the Property Trustee, of all or any part of such Trust Property, or to the extent required by law 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 the capacity aforesaid, any property, title, right or power deemed necessary or desirable, subject to the other provisions of this Section. If the Depositor does not join in such appointment
within 15 days after the receipt by it of a request so to do, or in case a Debenture Event of Default has occurred and is continuing, the Property Trustee alone shall have power to make such appointment. Any co-trustee or separate trustee appointed
pursuant to this Section shall either be (i) a natural person who is at least 21 years of age and a resident of the United States or (ii) a legal entity with its principal place of business in the United States that shall act through one or more
persons authorized to bind such entity. 
  
 Should any written
instrument from the Depositor be required by any co-trustee or separate trustee so appointed for more fully confirming 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 Depositor. 
  
 Every
co-trustee or separate trustee shall, to the extent permitted by law, but to such extent only, be appointed subject to the following terms, namely 
  
 (a) The Trust Securities shall be executed 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 Trustees specified hereunder shall be exercised solely by such Trustees and not by such co-trustee or separate trustee. 
  
 (b) The rights, powers, duties, and obligations hereby conferred or imposed
upon the Property Trustee in respect of any property covered by such appointment shall be conferred or imposed upon and exercised or performed by the Property Trustee or by the Property 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 Property 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 Property Trustee at any time, by an instrument in writing executed by it, with the written concurrence of the Depositor, may accept the
resignation of or remove any co-trustee or separate trustee appointed under this Section, and, in case a Debenture Event of Default has occurred and is continuing, the Property Trustee shall have power to accept the resignation of, or remove, any
such co-trustee or separate trustee without the concurrence of the Depositor. Upon the written request of the Property Trustee, the Depositor shall join with the Property Trustee in the execution, delivery and performance 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 Property Trustee or any other trustee hereunder. 
  
 (e) The Property Trustee shall not be liable by reason of any act of a co-trustee or separate trustee. 
  
 (f) Any Act of Holders delivered to the Property Trustee shall be deemed to have been delivered to each such co-trustee and separate trustee. 

 
 34 

 Section 8.10. Resignation and Removal; Appointment of Successor. 
  
 (a) No resignation or removal of any Trustee (the “Relevant
Trustee”) and no appointment of a successor Trustee pursuant to this Article shall become effective until the acceptance of appointment by the successor Trustee in accordance with the applicable requirements of Section 8.11. 
  
 (b) Subject to the immediately preceding paragraph, the Relevant Trustee may
resign at any time by giving written notice thereof to the Common Securityholder. If the instrument of acceptance by the successor Trustee required by Section 8.11 shall not have been delivered to the Relevant Trustee within 30 days after the giving
of such notice of resignation, the Relevant Trustee may petition, at the expense of the Trust, any court of competent jurisdiction for the appointment of a successor Relevant Trustee. 
  
 (c) Unless a Debenture Event of Default shall have occurred and be continuing, any Trustee may be removed at any time by Act
of the Common Securityholder. If a Debenture Event of Default shall have occurred and be continuing, the Property Trustee or the Delaware Trustee, or both of them, may be removed at such time by Act of the Holders of a majority in Liquidation Amount
of the Preferred Securities, delivered to the Relevant Trustee (in its individual capacity and on behalf of the Trust). If an instrument of acceptance by a successor Trustee shall not have been delivered to the Relevant Trustee within 30 days after
the giving of a notice of removal, the Relevant Trustee being removed may, at the expense of the Trust, petition any court of competent jurisdiction for the appointment of a successor Trustee. In no event will the Holders of the Preferred Securities
have the right to vote to appoint, remove or replace the Administrative Trustee. An Administrative Trustee may be removed by the Common Securityholder at any time. 
  
 (d) If any Trustee shall resign, be removed or become incapable of acting as Trustee, or if a vacancy shall occur in the
office of any Trustee for any cause, at a time when no Debenture Event of Default shall have occurred and be continuing, the Common Securityholder, by Act of the Common Securityholder delivered to the retiring Trustee, shall promptly appoint a
successor Trustee or Trustees, and the retiring Trustee shall comply with the applicable requirements of Section 8.11. If the Property Trustee or the Delaware Trustee shall resign, be removed or become incapable of continuing to act as the Property
Trustee or the Delaware Trustee, as the case may be, at a time when a Debenture Event of Default shall have occurred and be continuing, the Preferred Securityholders, by Act of the Securityholders of a majority in Liquidation Amount of the Preferred
Securities then Outstanding delivered to the retiring Relevant Trustee, shall promptly appoint a successor Relevant Trustee or Trustees, and such successor Trustee shall comply with the applicable requirements of Section 8.11. If an Administrative
Trustee shall resign, be removed or become incapable of acting as Administrative Trustee, at a time when a Debenture Event of Default shall have occurred and be continuing, the Common Securityholder by Act of the Common Securityholder delivered to
the Administrative Trustee shall promptly appoint a successor Administrative Trustee or Administrative Trustees and such successor Administrative Trustee or Trustees shall comply with the applicable requirements of Section 8.11. If no successor
Relevant Trustee shall have been so appointed by the Common Securityholder or the Preferred Securityholders and accepted appointment in the manner required by Section 8.11, any Securityholder who has been a Securityholder of Trust Securities for at
least six months may, on behalf of himself and all others similarly situated, petition any court of competent jurisdiction for the appointment of a successor Relevant Trustee. 
  
 (e) The Property Trustee shall give notice of each resignation and each removal of a Trustee and each appointment of a
successor Trustee to all Securityholders in the manner provided in Section 10.9 and shall give notice to the Depositor. Each notice shall include the name of the successor Relevant Trustee and the address of its Corporate Trust Office if it is tire
Property Trustee. 
  
 35 

 (f) Notwithstanding the foregoing or any other provision of this Trust Agreement, in the event any
Administrative Trustee or a Delaware Trustee who is a natural person dies or becomes, in the opinion of the Depositor, incompetent or incapacitated, the vacancy created by such death, incompetence or incapacity may be filled by (i) the unanimous act
of the remaining Administrative Trustees if there are at least two of them or (ii) otherwise by the Depositor (with the successor in each case being a Person who satisfies the eligibility requirement for Administrative Trustees or Delaware Trustee,
as the case may be, set forth in Section 8.7). 
  
 Section 8.11.
Acceptance of Appointment by Successor. 
  
 In
case of the appointment hereunder of a successor Relevant Trustee, the retiring Relevant Trustee and each successor Relevant Trustee with respect to the Trust Securities shall execute and deliver an amendment hereto wherein each successor Relevant
Trustee shall accept such appointment and which (a) shall contain such provisions as shall be necessary or desirable to transfer and confirm to, and to vest in, each successor Relevant Trustee all the rights, powers, trusts and duties of the
retiring Relevant Trustee with respect to the Trust Securities and the Trust and (b) shall add to or change any of the provisions of this Trust Agreement as shall be necessary to provide for or facilitate the administration of the Trust by more than
one Relevant Trustee, it being understood that nothing herein or in such amendment shall constitute such Relevant Trustees co-trustees and upon the execution and delivery of such amendment the resignation or removal of the retiring Relevant Trustee
shall become effective to the extent provided therein and each such successor Relevant Trustee, without any further act, deed or conveyance, shall become vested with all the rights, powers, trusts and duties of the retiring Relevant Trustee; but, on
request of the Trust or any successor Relevant Trustee such retiring Relevant Trustee shall duly assign, transfer and deliver to such successor Relevant Trustee all Trust Property, all proceeds thereof and money held by such retiring Relevant
Trustee hereunder with respect to the Trust Securities and the Trust. 
  
 Upon request of any such successor Relevant Trustee, the Trust shall execute any and all instruments for more fully and certainly vesting in and confirming to such successor Relevant Trustee all such rights, powers and trusts referred to in
the first or second preceding paragraph, as the case may be. 
  
 No successor Relevant Trustee shall accept its appointment unless at the time of such acceptance such successor Relevant Trustee shall be qualified and eligible under this Article. 
  
 Section 8.12. Merger, Conversion, Consolidation or Succession to
Business. 
  
 Any Person into which the Property
Trustee, the Delaware Trustee or any Administrative Trustee that is not a natural person may be merged or converted or with which it may be consolidated, or any corporation resulting from any merger, conversion or consolidation to which such
Relevant Trustee shall be a party, or any corporation succeeding to all or substantially all the corporate trust business of such Relevant Trustee, shall be the successor of such Relevant Trustee hereunder, provided that
such corporation shall be otherwise qualified and eligible under this Article, without the execution or filing of any paper or any further act on the part of any of the parties hereto. 
  
 Section 8.13. Preferential Collection of Claims Against Depositor or
Trust. 
  
 In case of the pendency of any
receivership, insolvency, liquidation, bankruptcy, reorganization, arrangement, adjustment, composition or other similar judicial proceeding relative to the Trust or any other obligor upon the Trust Securities or the property of the Trust or of such
other obligor or their creditors, the Property Trustee (irrespective of whether any Distributions on the Trust Securities shall then be due and payable as therein expressed or by declaration or otherwise and irrespective of whether the Property
Trustee shall have made any demand on the 
  
 36 

 Trust for the payment of any past due Distributions) shall be entitled and empowered, to the fullest extent permitted by
law, by intervention in such proceeding or otherwise: 
  
 (a) to
file and prove a claim for the whole amount of any Distributions owing and unpaid in respect of the Trust Securities and to file such other papers or documents as may be necessary or advisable in order to have the claims of the Property Trustee
(including any claim for the reasonable compensation, expenses, disbursements and advances of the Property Trustee, its agents and counsel) and of the Holders allowed in such judicial proceeding, and 
  
 (b) to collect and receive any moneys or other property payable or
deliverable on any such claims and to distribute the same; and any custodian, receiver, assignee, trustee, liquidator, sequestrator or other similar official in any such judicial proceeding is hereby authorized by each Holder to make such payments
to the Property Trustee and, in the event the Property Trustee shall consent to the making of such payments directly to the Holders, to pay to the Property Trustee any amount due it for the reasonable compensation, expenses, disbursements and
advances of the Property Trustee, its agents and counsel, and any other amounts due the Property Trustee. 
  
 Nothing herein contained shall be deemed to authorize the Property Trustee to authorize or consent to or accept or adopt on behalf of any Holder any plan
of reorganization, arrangement adjustment or compensation affecting the Trust Securities or the rights of any Holder thereof or to authorize the Property Trustee to vote in respect of the claim of any Holder in any such proceeding. If and when the
Property Trustee shall be or become a creditor of the Trust (or any other obligor upon the Trust Securities), the Property Trustee shall be subject to the provisions of the Trust Indenture Act regarding the collection of claims against the Trust (or
any such other obligor).

Trustee. 
  
 (a) Not later than [March 31] of each
year commencing with the year commencing January 1, 2004, the Property Trustee shall transmit to all Securityholders in accordance with Section 10.9, and to the Depositor, a brief report dated as of the immediately preceding December 31 with respect
to: 
  
 (i) its eligibility under Section 8.7 or, in lieu
thereof, if to the best of its knowledge it has continued to be eligible under said Section, a written statement to such effect; 
  
 (ii) a statement that the Property Trustee has complied with all of its obligations under this Trust Agreement during the twelve-month period (or, in the

reports concerning the Property Trustee and its actions under this Trust Agreement as may be required pursuant to the Trust Indenture Act at the times and in the manner provided pursuant thereto.

Holders, be filed by the Property Trustee with each national stock exchange, the Nasdaq National Market or such other interdealer quotation system or self-regulatory organization upon which the Trust Securities are listed or traded, with the
Commission and with the Depositor.

and at the times required by Section 314 of the Trust Indenture Act. Delivery of such reports, information and documents to the Property Trustee is for informational purposes only and the Property Trustee’s receipt of such shall not constitute
constructive notice of any information contained therein or determinable from information contained therein, including the Depositor’s and Administrative Trustees’ compliance with any of its covenants hereunder (as to which the Property
Trustee is entitled to conclusively rely exclusively on Officers’ Certificates). 
  
 Section 8.16. Evidence of Compliance with Conditions Precedent. 
  
 Each of the Depositor and the Administrative Trustees on behalf of the Trust shall provide to the Property Trustee such evidence of compliance with any
conditions precedent, if any, provided for in this Trust Agreement that relate to any of the matters set forth in Section 314(c) of the Trust Indenture Act. Any certificate or opinion required to be given by an officer pursuant to Section 314(c)(1)
of the Trust Indenture Act shall be given in the form of an Officers’ Certificate. 
  
 Section 8.17. Number of Trustees. 
  
 (a) The number of Trustees shall be five (5) provided that the Holder of all of the Common Securities by written instrument may increase or decrease the number of Administrative Trustees. The Property Trustee and the Delaware Trustee may be
the same Person. 
  
 (b) If a Trustee ceases to hold office for
any reason and the number of Administrative Trustees is not reduced pursuant to Section 8.17(a), or if the number of Trustees is increased pursuant to Section 8.17(a), a vacancy shall occur. The vacancy shall be filled with a Trustee appointed in
accordance with Section 8.10. 
  
 (c) The death, resignation,
retirement, removal, bankruptcy, 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 8.10, the Administrative Trustees in office, regardless of their number (and notwithstanding any other provision of this Trust Agreement), shall have all the powers
granted to the Administrative Trustees and shall discharge all the duties imposed upon the Administrative Trustees by this Trust Agreement. 
  
 Section 8.18. Delegation of Power. 
  
 (a) Any Administrative Trustee may, by power of attorney consistent with applicable law, delegate to any other natural person over the age of 21 his or
her power for the purpose of executing any documents contemplated in Section 2.7(a), 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 the Depositor 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 Trust Agreement, as set forth herein. 
  
 38 

 Section 8.19. Voting.

 Section 9.1. Dissolution Upon Expiration Date. 
  
 Unless dissolved earlier, the Trust shall automatically dissolve on             , 2034
{maturity date in registration statement?} (the “Expiration Date”), following the distribution of the Trust Property in accordance with Section 9.4. 
  
 Section 9.2. Early Dissolution. 
  
 The first to occur of any of the following events is an “Early Dissolution Event,” upon the
occurrence of which the Trust shall dissolve: 
  
 (a) the
occurrence of a Bankruptcy Event in respect of, or the dissolution or liquidation of, the Depositor; 
  
 (b) the written direction to the Property Trustee from the Depositor at any time to dissolve the Trust and distribute Debentures to Securityholders in
exchange for a Like Amount of the Preferred Securities (which direction is optional and wholly within the discretion of the Depositor); 
  
 (c) the redemption of all of the Preferred Securities in connection with the redemption of all the Debentures; and 
  
 (d) the entry of an order for dissolution of the Trust by a court of
competent jurisdiction. 
  
 Section 9.3. Dissolution.

  
 The respective obligations and responsibilities of
the Trustees and the Trust created and continued hereby shall dissolve upon the latest to occur of the following: 
  
 (i) the distribution by the Property Trustee to Securityholders upon the liquidation of the Trust pursuant to Section 9.4; or upon the redemption of all
of the Trust Securities pursuant to Section 4.2, of all amounts required to be distributed hereunder upon the final payment of the Trust Securities; 
  
 (ii) the payment of any expenses owed by the Trust; and 
  
 (iii) the discharge of all administrative duties of the Administrative Trustees, including the performance of any tax reporting obligations with respect
to the Trust or the Securityholders, and 
  
 (iv) the filing of a
Certificate of Cancellation by the Administrative Trustee under the Delaware Statutory Trust Act. 
  
 39 

 Section 9.4. Liquidation. 
  
 (a) If an Early Dissolution Event specified in clause (a), (b) or (d) of Section 9.2 occurs or upon the Expiration Date, the
Trust shall be liquidated by the Trustees as expeditiously as the Trustees determine to be possible by distributing, after satisfaction of liabilities to creditors of the Trust as provided by applicable law, to each Securityholder a Like Amount of
Debentures, subject to Section 9.4(d). Notice of liquidation shall be given by the Property Trustee by first-class mail, postage prepaid mailed not later than 30 nor more than 60 days prior to the Liquidation Date to each Holder of Trust Securities
at such Holder’s address appearing in the Securities Register. All notices of liquidation shall: 
  
 (i) state the Liquidation Date; 
  
 (ii) state that from and after the Liquidation Date, the Trust Securities will no longer be deemed to be Outstanding and any Trust Securities Certificates
not surrendered for exchange will be deemed to represent a Like Amount of Debentures; and 
  
 (iii) provide such information with respect to the mechanics by which Holders may exchange Trust Securities Certificates for certificates representing the Like Amount of the Debentures, or if Section 9.4(d) applies
receive a Liquidation Distribution, as the Administrative Trustees or the Property Trustee shall deem appropriate. 
  
 (b) Except where Section 9.2(c) or 9.4(d) applies, in order to effect the liquidation of the Trust and distribution of the Debentures to Securityholders,
the Administrative Trustees shall establish a record date for such distribution (which shall be not more than 45 days prior to the Liquidation Date) and, either itself acting as exchange agent or through the appointment of a separate exchange agent,
shall establish such procedures as it shall deem appropriate to effect the distribution of Debentures in exchange for the Outstanding Trust Securities Certificates. 
  
 (c) Except where Section 9.2(c) or 9.4(d) applies, after the Liquidation Date, (i) the Trust Securities will no longer be
deemed to be Outstanding, (ii) certificates representing a Like Amount of Debentures will be issued to holders of Trust Securities Certificates, upon surrender of such certificates to the Administrative Trustees or their agent for exchange, (iii)
the Depositor shall use its best efforts to have the Debentures listed on the Nasdaq National Market or on such other exchange, interdealer quotation system or self-regulatory organization as the Preferred Securities are then listed, (iv) any Trust
Securities Certificates not so surrendered for exchange will be deemed to represent a Like Amount of Debentures, accruing interest at the rate provided for in the Debentures from the last Distribution Date on which a Distribution was made on such
Trust Securities Certificates until such certificates are so surrendered (and until such certificates are so surrendered, no payments of interest or principal will be made to Holders of Debentures represented by such certificates) and (v) all rights
of Securityholders holding Trust Securities will cease, except the right of such Securityholders to receive a Like Amount of Debentures upon surrender of Trust Securities Certificates. 
  
 (d) In the event that, notwithstanding the other provisions of this Section 9.4, whether because of an order for dissolution
entered by a court of competent jurisdiction or otherwise, distribution of the Debentures in the manner provided herein is deemed not to be practical, the Trust Property shall be liquidated, and the Trust shall be wound-up or terminated, by the
Property Trustee in such manner as the Property Trustee determines. In such event, on the date of the dissolution of the Trust, Securityholders will be entitled to receive out of the assets of the Trust available for distribution to Securityholders,
after satisfaction of liabilities to creditors of the Trust as provided by applicable law, an amount equal to the Liquidation Amount per Trust Security plus accumulated and unpaid Distributions thereon to the date of payment (such amount being the
“Liquidation Distribution”). If, upon any such winding up or termination, the Liquidation Distribution can be paid only in part because the Trust has insufficient assets available to pay in full the aggregate Liquidation
Distribution, then, subject to the next succeeding sentence, the 
  
 40 
  

 amounts payable by the Trust on, the Trust Securities shall be paid on a pro rata basis (based upon Liquidation Amounts).
The Holder of the Common Securities will be entitled to receive Liquidation Distributions upon any such winding-up or termination pro rata (determined as aforesaid) with Holders of Preferred Securities, except that, if a Debenture Event of Default
has occurred and is continuing, Holders of the Preferred Securities shall have a priority over the Holders of Common Securities. 
  
 Section 9.5. Mergers, Consolidations, Amalgamations or Replacements of the Trust. 
  
 The Trust may not merge with or into, consolidate, amalgamate, or be replaced
by, or convey, transfer or lease its properties and assets substantially as an entirety to any corporation or other body, except pursuant to this Section 9.5 or Section 9.4. At the request of the Depositor, with the consent of the Administrative
Trustees and without the consent of the Holders of the Preferred Securities, the Property Trustee or the Delaware Trustee, the Trust may merge with or into, consolidate, amalgamate, or be replaced by or convey, transfer or lease its properties and
assets substantially as an entirety to a trust organized as such under the laws of any State, provided, that: 
  
 (a) such successor entity either (i) expressly assumes all of the obligations of the Trust with respect to the Preferred Securities, or (ii) substitutes
for the Preferred Securities other securities having substantially the same terms as the Preferred Securities (the “Successor Securities”) so long as the Successor Securities rank the same as the Preferred Securities rank in
priority with respect to distributions and payments upon liquidation, redemption and otherwise, 
  
 (b) the Depositor expressly appoints a trustee of such successor entity possessing the same powers and duties as the Property Trustee as the holder of the
Debentures, 
  
 (c) the Successor Securities are listed or traded,
or any Successor Securities will be listed upon notification of issuance, on any national securities exchange or other organization on which the Preferred Securities are then listed or traded, if any, 
  
 (d) such merger, consolidation, amalgamation, replacement, conveyance,
transfer or lease does not cause the Preferred Securities (including any Successor Securities) to be downgraded by any nationally recognized statistical rating organization, 
  
 (e) such merger, consolidation, amalgamation, replacement, conveyance, transfer or lease does not adversely affect the
rights, preferences and privileges of the holders of the Preferred Securities (including any Successor Securities) in any material respect, 
  
 (f) such successor entity has a purpose substantially identical to that of the Trust, 
  
 (g) prior to such merger, consolidation, amalgamation, replacement, conveyance, transfer or lease, the Depositor, the
Property Trustee and the Delaware Trustee have received an Opinion of Counsel to the effect that (i) such merger, consolidation, amalgamation, replacement, conveyance, transfer or lease does not adversely affect the rights, preferences and
privileges of the holders of the Preferred Securities (including any Successor Securities) in any material respect, and (ii) following such merger, consolidation, amalgamation, replacement, conveyance, transfer or lease, neither the Trust nor such
successor entity will be required to register as an investment company under the 1940 Act, and 
  
 (h) the Depositor owns all of the Common Securities of such successor entity and guarantees the obligations of such successor entity under the Successor Securities at least to the extent provided by the Guarantee.

  
 41 

 Notwithstanding the foregoing, the Trust shall not, except with the consent of holders of 100% in Liquidation Amount of
the Preferred Securities, consolidate, amalgamate, merge with or into, or be replaced by or convey, transfer or lease its properties and assets substantially as an entirety to any other entity or permit any other entity to consolidate, amalgamate,
merge with or into, or replace it if such consolidation, amalgamation, merger, replacement, conveyance, transfer or lease would cause the Trust or the successor entity to be classified as other than a grantor trust for United States federal income
tax purposes.

investment company under the 1940 Act.

a grantor trust for United States federal income tax purposes, or (iii) cause the Preferred Securities to be delisted by the Nasdaq National Market or such other national exchange or over-the-counter market on which the Preferred Securities are then
listed for trading.

Agreement to the contrary, without the consent of the Delaware Trustee or the Depositor, as the case may be, this Trust Agreement may not be amended in a manner which imposes any additional obligation on the Depositor or the Delaware Trustee.

any Person except to a Holder exercising his or her rights pursuant to Section 5.4(d) or to a Successor Guarantee Trustee on acceptance by such Successor Guarantee Trustee of its appointment to act as Successor Guarantee Trustee. The right, title
and interest of the Guarantee Trustee shall automatically vest in any Successor Guarantee Trustee, upon acceptance by such Successor Guarantee Trustee of its appointment hereunder, and such vesting and cessation of title shall be effective whether

and after the curing of all Events of Default that may have occurred, shall undertake to perform only such duties as are specifically set forth in this Guarantee Agreement, and no implied covenants or obligations shall be read into this Guarantee
Agreement against the Guarantee Trustee. In case an Event of Default has occurred (that has not been cured or waived pursuant to Section 2.6), the Guarantee Trustee shall exercise such of the rights and powers vested in it by this Guarantee
Agreement, and use the same degree of care and skill in its exercise thereof, as a prudent person would exercise or use under the circumstances in the conduct of his or her own affairs. 
  
 (d) No provision of this Guarantee Agreement shall be construed to relieve the Guarantee Trustee from liability for its own
negligent action, its own negligent failure to act or its own willful misconduct, except that: 
  

 5 

 (i) prior to the occurrence of any 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 Guarantee Trustee shall be determined solely by the express provisions of this Guarantee Agreement, and the Guarantee Trustee shall not be liable except for the performance of such duties and
obligations as are specifically set forth in this Guarantee Agreement; and 
  
 (B) in the absence of bad faith on the part of the Guarantee Trustee, the Guarantee Trustee may conclusively rely, as to the truth of the statements and the correctness of the opinions expressed therein, upon any
certificates or opinions furnished to the Guarantee Trustee and conforming to the requirements of this Guarantee Agreement; but in the case of any such certificates or opinions that by any provision hereof or of the Trust Indenture Act are
specifically required to be furnished to the Guarantee Trustee, the Guarantee Trustee shall be under a duty to examine the same to determine whether or not they conform to the requirements of this Guarantee Agreement; 
  
 (ii) The Guarantee Trustee shall not be liable for any error
of judgment made in good faith by a Responsible Officer of the Guarantee Trustee, unless it shall be proved that the Guarantee Trustee was negligent in ascertaining the pertinent facts upon which such judgment was made; 
  
 (iii) the Guarantee Trustee shall not be liable with respect
to any action taken or omitted to be taken by it in good faith in accordance with the direction of the Holders of not less than a Majority in Liquidation Amount of the Preferred Securities relating to the time, method and place of conducting any
proceeding for any remedy available to the Guarantee Trustee, or exercising any trust or power conferred upon the Guarantee Trustee under this Guarantee Agreement; and 
  
 (iv) no provision of this Guarantee Agreement shall require the Guarantee Trustee to expend or risk its own
funds or otherwise incur personal financial liability in the performance of any of its duties or in the exercise of any of its rights or powers, if the Guarantee Trustee shall have reasonable grounds for believing that the repayment of such funds or
liability is not reasonably assured to it under the terms of this Guarantee Agreement or indemnity reasonably satisfactory to the Guarantee Trustee against such risk or liability is not reasonably assured to it. 
  
 SECTION 3.2. Certain Rights of Guarantee Trustee.

fully protected in acting or refraining from acting upon any resolution, certificate, statement, instrument, opinion, report, notice, request, direction, consent, order, bond, debenture, note, other evidence of indebtedness or other paper or
document reasonably believed by it to be genuine and to have been signed, sent or presented by the proper party or parties. 
  
 (ii) Any direction or act of the Guarantor contemplated by this Guarantee Agreement shall be sufficiently evidenced by an Officers’
Certificate unless otherwise prescribed herein.

(unless other evidence is herein specifically prescribed) may, in the absence of bad faith on its part, request and rely 
  

 6 

 upon an Officers’ Certificate which, upon receipt of such request from the Guarantee Trustee; shall
be promptly delivered by the Guarantor. 
  
 (iv)
The Guarantee Trustee may consult with legal counsel, and the advice or opinion of such legal counsel with respect to legal matters shall be full and complete authorization and protection in respect of any action taken, suffered or omitted to be
taken by it hereunder in good faith and in accordance with such advice or opinion. Such legal counsel may be legal counsel to the Guarantor or any of its Affiliates and may be one of its employees. The Guarantee Trustee shall have the right at any
time to seek instructions concerning the administration of this Guarantee Agreement from any court of competent jurisdiction. 
  
 (v) The Guarantee Trustee shall be under no obligation to exercise any of the rights or powers vested in it by this Guarantee Agreement at
the request or direction of any Holder, unless such Holder shall have provided to the Guarantee Trustee such security and indemnity reasonably satisfactory to the Guarantee Trustee, against the costs, expenses (including attorneys’ fees and
expenses) and liabilities that might be incurred by it in complying with such request or direction, including such reasonable advances as may be requested by the Guarantee Trustee; provided that, nothing contained in this Section 3.2(a)(v) shall be
taken to relieve the Guarantee Trustee, upon the occurrence of an Event of Default, of its obligation to exercise the rights and powers vested in it by this Guarantee Agreement. 
  
 (vi) The Guarantee Trustee shall not be bound to make any investigation into the facts or matters stated in
any resolution, certificate, statement, instrument, opinion, report, notice, request, direction, consent, order, bond, debenture, note, other evidence of indebtedness or other paper or document, but the Guarantee Trustee, in its discretion, may,
make such further inquiry or investigation into such facts or matters as it may see fit. 
  
 (vii) The Guarantee Trustee may execute any of the trusts or powers hereunder or perform any duties hereunder either directly or by or
through its agents or attorneys, and the Guarantee Trustee shall not be responsible for any misconduct or negligence on the part of any such agent or attorney appointed with due care by it hereunder. 
  
 (viii) Whenever in the administration of this Guarantee
Agreement the Guarantee Trustee shall deem it desirable to receive instructions with respect to enforcing any remedy or right or taking any other action hereunder, the Guarantee Trustee (A) may request instructions from the Holders of a majority in
liquidation amount of the Preferred Securities, (B) may refrain from enforcing such remedy or right or taking such other action until such instructions are received, and (C) shall be protected in acting in accordance with such instructions.

  
 (b) No provision of this Guarantee Agreement shall be deemed
to impose any duty or obligation on the Guarantee Trustee to perform any act or acts or exercise any right, power, duty or obligation conferred or imposed on it in any jurisdiction in which it shall be illegal, or in which the Guarantee Trustee
shall be unqualified or incompetent in accordance with applicable law, to perform any such act or acts or to exercise any such right, power, duty or obligation. No permissive power or authority available to the Guarantee Trustee shall be construed
to be a duty to act in accordance with such power and authority. 
  
 (c) The Guarantee Trustee shall have no duty to see to any recording, filing or registration of any instrument (or any rerecording, refilling or re-registration thereof). 
  
 SECTION 3.3.    Indemnity. 
  
 (a) The Guarantor agrees to indemnify the Guarantee Trustee for, and to hold
it harmless against, any and all loss, liability or expense (including taxes (other than taxes based upon the income of the Guarantee Trustee) incurred without negligence or bad faith on the part of the Guarantee Trustee, arising out of or in
connection with the acceptance or administration of 
  

 7 

 this Guarantee Agreement, including the costs and expenses (including reasonable legal fees and expenses) of defending
itself against any claim or liability in connection with the exercise or performance of any of its powers or duties hereunder. 
  
 (b) The provisions of this Section 3.3 shall survive the termination of the Guarantee Agreement or the resignation or removal of the Guarantee Trustee.
When the Guarantee Trustee incurs expenses or renders services in connection with an Event of Default specified in Section 5.1(d) or Section 5.1(e) of the Indenture, the expenses (including the reasonable legal fees and expenses) and the
compensation for services are intended to constitute expenses of administration under any applicable federal or state bankruptcy, insolvency or other similar law.
