Except as set forth herein, the rights of owners of beneficial interests in any Global Unit shall be exercised only through the Depositary subject to the applicable rules and procedures of the Depositary.

Upon the issuance of any new Unit Certificate under this Section, the Company and the Units Trustee may require the payment of a sum sufficient to cover any tax or other governmental charge that may be imposed in relation thereto and any other expenses (including the fees and expenses of the Units Trustee) connected therewith.

Every new Unit Certificate executed pursuant to this Section in lieu of any destroyed, lost or stolen Unit Certificate shall constitute an original additional contractual obligation of the Company, whether or not the destroyed, lost or stolen Unit Certificate (and the Securities evidenced thereby) shall be at any time enforceable by anyone, and shall be entitled to all the benefits of this Agreement equally and proportionately with any and all other Unit Certificates delivered hereunder.

The provisions of this Section are exclusive and shall preclude (to the extent lawful) all other rights and remedies with respect to the replacement or payment of mutilated, destroyed, lost or stolen Unit Certificates.

(a) Upon any of (i) the receipt by the Units Trustee, in accordance with Section 3.02, of a Holder Separation Notice, (ii) the receipt by the Units Trustee, in accordance with Section 3.01, of an Automatic Unit Separation Event Notice, or (iii) October 27, 2023, if any Units remain outstanding on such date, the Units Trustee shall promptly cause to be separated the Common Shares and the Notes related to the Units subject to the relevant Automatic Unit Separation Date, and all such Units shall be cancelled, and the applicable Common Shares and Notes shall be freely transferrable (subject to applicable securities laws); provided that, in the case of clauses (ii) and (iii) above, the Company shall deliver to the Units Trustee and DTC the necessary documentation to process a mandatory exchange of securities eligible at DTC; provided, further, that in the case of clause (iii), in order for the Units Trustee to effect the separation of Units on October 27, 2023 without delay, such necessary documentation shall be delivered on or prior to October 12, 2023. Whenever Global Units are separated, the Units Trustee shall give effect to such separation by causing Schedule A of the Global Unit to be endorsed and the Unit Register to be updated to reflect any decrease in the Global Units as a result of such separation, and the Trustee shall cause the Schedule of Decreases of the Attached Notes (representing the Notes prior to such separation that form a part of the Units) and Schedule of Increases and Decreases of the Global Notes (representing the Notes following such separation) to be endorsed to reflect such separation.

(b) Upon the completion of the foregoing procedures, generally within one Business Day of such Automatic Unit Separation Date, (i) the Notes that previously formed a part of the Units prior to such separation may be transferred, assigned or exchanged by the Holder thereof separately, and will be represented by separate interests on the books of the Trustee and (ii) the Common Shares that previously formed a part of the Units prior to such separation will be delivered by the Units Trustee to the Holders of such Units, with each such Holder receiving five Common Shares per $1,000 stated amount of Units held. The Company will have used commercially reasonable efforts to procure CUSIP numbers for such securities, and to have such CUSIP numbers made eligible for DTC, for such purpose prior to the date of separation, in the form of one or more fully registered global securities which will be deposited with, or on behalf of, DTC and will be registered in the name of a nominee of DTC. The Notes and Common Shares that previously formed a part of the Units prior to such separation shall be delivered free from any restrictive legends. Upon the completion of such procedures, the Units Trustee shall inform each Holder (or the holder of a beneficial interest in any Global Unit) of such completion within one Business Day.

Section 5.06 Corporate Agent Required; Eligibility. There shall at all times be a trustee hereunder which shall be a corporation organized and doing business under the laws of the United States of America, any state thereof or the District of Columbia, having, together with its parent, a combined capital and surplus of at least $50,000,000, subject to supervision or examination by federal, state or District of Columbia authority and willing to act on reasonable terms. If such corporation, or its parent, publishes reports of condition at least annually, pursuant to law or to the requirements of the aforesaid supervising or examining authority, then for the purposes of this Section, the combined capital and surplus of such corporation shall be deemed to be its combined capital and surplus as set forth in its most recent report of condition so published. The Units Trustee hereunder shall at all times be the Trustee under the Indenture, subject to receipt of an Opinion of Counsel that the same Person is precluded by law from acting in such capacities. If at any time the Units Trustee 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 Section 5.07.

(b) The Units Trustee may resign by giving written notice thereof to the Company and the Holders, in accordance with Section 6.06 and 6.07, 60 days prior to the effective date of such resignation. The Units Trustee may be removed at any time upon 60 days’ notice by the filing with it of an instrument in writing signed on behalf of the Company and specifying such removal and the date when it is intended to become effective. If the instrument of acceptance by a successor Units Trustee required by Section 5.08 shall not have been delivered to the Units Trustee within 30 days after the giving of such notice of resignation, the resigning Units Trustee may petition any court of competent jurisdiction, at the expense of the Company, for the appointment of a successor Units Trustee.

(c) If at any time (i) the Units Trustee shall cease to be eligible under Section 5.06, or shall cease to be eligible as Trustee under the Indenture, and shall fail to resign after written request therefor by the Company or by any Holder, or (ii) the Units Trustee shall become incapable of acting with respect to the Units or shall be adjudged a bankrupt or insolvent, or a receiver or liquidator of the Units Trustee or of its property shall be appointed or any public officer shall take charge or control of the Units Trustee or of its property or affairs for the

17

purpose of rehabilitation, conservation or liquidation, then, in any such case, (A) the Company, by Board Resolution, may remove the Units Trustee and appoint a successor Units Trustee, or (B) any Holder who has been a bona fide Holder of Units for at least six months may, on behalf of himself and all others similarly situated, petition any court of competent jurisdiction, at the expense of the Company, for the removal of the Units Trustee and the appointment of a successor Units Trustee or Trustees. Such court may thereupon, after such notice, if any, as it may deem proper and prescribe, remove the Units Trustee and appoint a successor Units Trustee.

(d) If the Units Trustee shall resign, be removed or become incapable of acting, or if a vacancy shall occur in the office of the Units Trustee for any cause, the Company, by Board Resolution, shall promptly appoint a successor Units Trustee or Trustees (other than the Company) and shall comply with the applicable requirements of Section 5.08. If no successor Units Trustee shall have been so appointed by the Company and accepted appointment in the manner required by Section 5.08, any Holder who has been a bona fide Holder of Units for at least six months may, on behalf of itself and all others similarly situated, petition any court of competent jurisdiction, at the expense of the Company, for the appointment of a successor Units Trustee.

(e) The Company shall give, or shall cause such successor Units Trustee to give, notice of each resignation and each removal of the Units Trustee and each appointment of a successor Units Trustee to all Holders of Units in accordance with Section 6.07. Each notice shall include the name of the successor Units Trustee and the address of its Corporate Trust Office.

Section 5.08 Acceptance of Appointment by Successor.

(a) In case of the appointment hereunder of a successor Units Trustee, every such successor Units Trustee so appointed shall execute, acknowledge and deliver to the Company and to the retiring Units Trustee an instrument accepting such appointment, and thereupon the resignation or removal of the retiring Units Trustee shall become effective and such successor Units Trustee, without any further act, deed or conveyance, shall become vested with all the rights, powers, agencies and duties of the retiring Units Trustee, with like effect as if originally named as Units Trustee hereunder; but, on the request of the Company or the successor Units Trustee, such retiring Units Trustee shall, upon payment of all amounts due and payable to it pursuant to Section 5.05, execute and deliver an instrument transferring to such successor Units Trustee all the rights and powers of the retiring Units Trustee and shall duly assign, transfer and deliver to such successor Units Trustee all property and money held by such retiring Units Trustee hereunder. Any retiring Units Trustee shall, nonetheless, retain a prior claim upon all property or funds held or collected by such Units Trustee to secure any amounts then due it pursuant to Section 5.05.

(b) Upon request of any such successor Units Trustee, the Company shall execute any and all instruments for more fully and certainly vesting in and confirming to such successor Units Trustee all such rights, powers and agencies referred to in Section 5.08(a).

(c) No successor Units Trustee shall accept its appointment unless at the time of such acceptance such successor Units Trustee shall be eligible under Section 5.06.

18

(d) Upon acceptance of appointment by any successor Units Trustee as provided in this Section, the Company shall give notice thereof to the Holders of Units in accordance with Section 6.07. If the acceptance of appointment is substantially contemporaneous with the resignation of the Units Trustee, then the notice called for by the preceding sentence may be combined with the notice called for by Section 5.07. If the Company fails to give such notice within ten days after acceptance of appointment by the successor Units Trustee, the successor Units Trustee shall cause such notice to be given at the expense of the Company.

Section 5.09 Merger, Conversion, Consolidation or Succession to Business. Any Person that is an entity into which the Units Trustee may be merged or converted or with which it may be consolidated, or any Person that is an entity resulting from any merger, conversion or consolidation to which the Units Trustee shall be a party, or any Person that is an entity succeeding to all or substantially all the agency business of the Units Trustee, shall be the successor of the Units Trustee hereunder, without the execution or filing of any paper or any further act on the part of any of the parties hereto, provided that such Person shall be otherwise eligible under this Article.

Section 5.10 Tax Compliance.

(a) The Units Trustee, on its own behalf and on behalf of the Company, will comply with all applicable certification, information reporting and withholding (including “backup” withholding) requirements imposed by applicable United States federal and state tax laws, regulations or administrative practice (i) with respect to payments on, or transfer or redemption of the Notes or the Common Shares or (ii) if specifically instructed by the Company, with respect to the issuance, delivery, holding or exercise of rights (other than by payment, transfer or redemption) under the Notes or the Common Shares. Such compliance shall include, without limitation, the preparation and timely filing of required returns with respect to, and the timely payment of, all amounts required to be withheld to the appropriate taxing authority or its designated agent. The Company will provide to the Units Trustee such information as it may reasonably request in order to comply with this Section.

(b) The Units Trustee shall comply with any direction received from the Company with respect to the application of such requirements to particular payments or holders or in other particular circumstances, and may for purposes of this Agreement rely on any such direction in accordance with the provisions of Section 5.01(b)(ii).

(c) The Units Trustee shall maintain all appropriate records documenting compliance with such requirements, and shall make such records available on request at reasonable times during normal business hours to the Company or to its authorized representatives duly authorized in writing.

MISCELLANEOUS PROVISIONS

Section 6.01 Amendments.

(a) This Agreement and the terms of the Units may be amended (by means of an agreement supplemental hereto or otherwise) by the Company and the Units Trustee, without the consent of the Holders, (i) for the purpose of curing any ambiguity, or of curing, correcting or supplementing any defective or inconsistent provision contained herein or therein, (ii) to evidence and provide for the acceptance of appointment hereunder by a successor Units Trustee with respect to the Units, (iii) for the purposes of providing for compliance with the applicable securities laws (to the extent there are changes in applicable law following the date hereof), (iv) to conform the text of this Agreement to any provision of the “Description of units” contained in the Prospectus Supplement, to the extent that such provision is intended to be a substantially verbatim recitation of a provision of this Agreement or (v) in any other manner which the Company may deem necessary or desirable and which will not adversely affect the interests of the affected Holders.

(b) The Company and the Units Trustee may modify or amend this Agreement (by means of an agreement supplemental hereto or otherwise) with the consent of Holders holding not less than a majority in aggregate stated amount of the then Outstanding Units affected thereby for any purpose; provided, however, that no such modification or amendment that materially and adversely affects (i) the separation rights of the affected Holders or reduces the percentage of the stated amount of Outstanding Units the consent of the Holders of which is required for modification or amendment of this Agreement or (ii) any Key Provision or any Key Definition may be made without the consent of each Holder materially and adversely affected thereby. In the case of Units evidenced by one or more Global Unit Certificates, the Company and the Units Trustee shall be entitled to rely upon certification in form satisfactory to each of them that any requisite consent has been obtained from holders of beneficial ownership interests in the relevant Global Unit Certificate. Such certification may be provided by participants of the Depositary acting on behalf of such beneficial owners of Units, provided that any such certification is accompanied by a certification from the Depositary as to the Unit holdings of such participants. For purposes hereof, “Key Provisions” shall mean each of Sections 2.02, 2.03, 3.01, 3.02, 3.03 and 4.01 and this Section 6.01, and “Key Definitions” shall mean “Automatic Unit Separation Date,” “Automatic Unit Separation Event Notice,” “Unit” and any defined term that has the meaning set forth in the Indenture. For the avoidance of doubt, any and all calculations or determinations made by the Company, the Units Trustee, the Trustee or their authorized representatives in accordance with the Key Provisions and Key Definitions shall not be considered an amendment or modification of this Agreement.

(c) Upon the request of the Company, accompanied by a copy of a Board Resolution (which Board Resolution may provide general terms or parameters for such action and may provide that the specific terms of such action may be determined in accordance with or pursuant to an Officer’s Certificate) authorizing the execution of any such amendment, and upon the filing with the Units Trustee of evidence of the consent of Holders as aforesaid, the Units Trustee shall join with the Company in the execution of such amendment unless such amendment affects the Units Trustee’s own rights, duties or immunities under this Agreement or otherwise, in which case the Units Trustee may in its discretion, but shall not be obligated to, enter into such amendment. In executing, or accepting the additional duties created by any amendment permitted by this Section, the Units Trustee shall receive, and shall be fully protected in relying upon, an Opinion of Counsel stating that the execution of such amendment is authorized or permitted by this Agreement and is enforceable against the Company in accordance with its terms. The fact and date of the execution of any consent of Holders, or the authority of the Person executing the same, may be proved by the certificate of any notary public or other officer

20

of any jurisdiction authorized to take acknowledgments of deeds or administer oaths that the person executing such instruments acknowledged to him the execution thereof, or by an affidavit of a witness to such execution sworn to before any such notary or other such officer. Where such execution is by or on behalf of any legal entity other than an individual, such certificate or affidavit shall also constitute sufficient proof of the authority of the person executing the same. The ownership of Registered Units shall be proved by the Unit Register or by a certificate of the Units Trustee, as registrar for the Units. For the avoidance of doubt, such action may relate to the Units as well as to its constituent Securities, this Agreement and the Indenture for so long as any Units have not separated pursuant to Article 3. The Depositary shall report only one result of each solicitation of proxies to the Units Trustee.

(d) It shall not be necessary for the consent of the Holders under this Section to approve the particular form of any proposed amendment, but it shall be sufficient if such consent shall approve the substance thereof.

(e) The Company may set a record date for purposes of determining the identity of Holders of Registered Units entitled to consent to any action by consent authorized or permitted hereby. Such record date shall be the later of 30 days prior to the first solicitation of such consent or the date of the most recent list of Holders of Registered Units furnished to the Units Trustee. The ownership of Registered Units shall be proved by the Unit Register. The Units Trustee shall vote as the custodian of the Common Shares and Notes in respect of any action relating to such Securities or the Indenture in the manner directed by the Holders of the Registered Units. Any notices received by the Units Trustee shall be distributed to Holders of Units within two Business Days.

Section 6.02 Incorporators, Shareholders, Officers and Directors of the Company Immune from Liability. No recourse under or upon any obligation, covenant or agreement contained in this Agreement, or in any Notes, or because of any indebtedness evidenced thereby, shall be had against any incorporator, or against any past, present or future shareholder, officer, attorney-in-fact or director, as such, of the Company or of any successor corporation, either directly or through the Company or any successor corporation, under any rule of law, statute or constitutional provision or by the enforcement of any assessment or penalty or by any legal or equitable proceeding or otherwise, all such liability being expressly waived and released by the acceptance of the Units by the Holders thereof and as part of the consideration for the issue thereof, provided that nothing in this Article shall impair the obligations, covenants and agreements of the Company contained in this Agreement and in any Notes constituting a part of the Units.

Section 6.03 Compliance Certificates and Opinions. Except as otherwise expressly provided by this Agreement (including, for the avoidance of doubt, any action related to the separation of Units pursuant to Article 3 of this Agreement), upon any application or request by the Company to the Units Trustee to take any action under any provision of this Agreement, the Company, as applicable, shall furnish to the Units Trustee an Officer’s Certificate stating that all conditions precedent, if any, provided for in this Agreement relating to the proposed action have been complied with and an Opinion of Counsel stating that, in the opinion of such counsel, all such conditions precedent, if any, have been complied with, except that in the case of any such application or request as to which the furnishing of such documents is specifically required by any provision of this Agreement relating to such particular application or request, no additional certificate or opinion need be furnished.

21

Every certificate or opinion with respect to compliance with a condition or covenant provided for in this Agreement shall include:

(a) a statement that each individual signing such certificate or opinion has read such covenant or condition and the definitions herein relating thereto;

(b) a brief statement as to the nature and scope of the examination or investigation upon which the statements or opinions contained in such certificate or opinion are based;

(c) a statement that, in the opinion of each such individual, he or she has made such examination or investigation as is necessary to enable him or her to express an informed opinion as to whether or not such covenant or condition has been complied with; and

(d) a statement as to whether, in the opinion of each such individual, such condition or covenant has been complied with.

Section 6.04 Form of Documents Delivered to Units Trustee. In any case where several matters are required to be certified by, or covered by an opinion of, any specified Person, it is not necessary that all such matters be certified by, or covered by the opinion of, only one such Person, or that they be so certified or covered by only one document, but one such Person may certify or give an opinion with respect to some matters and one or more other such Persons as to other matters, and any such Person may certify or give an opinion as to such matters in one or several documents.

Any certificate, statement or opinion of an officer or Opinion of Counsel of or for the Company may be based, insofar as it relates to legal matters, upon a certificate or opinion of, or representations by, counsel, unless such officer knows, or in the exercise of reasonable care should know, that the certificate or opinion or representations with respect to the matters upon which his certificate, statement or opinion is based are erroneous. Any such certificate, statement or opinion may be based, insofar as it relates to factual matters, upon a certificate, statement or opinion of, or representations by, an officer or officers of the Company, as applicable, stating that the information with respect to such factual matters is in the possession of the Company, unless such counsel knows, or in the exercise of reasonable care should know, that the certificate or opinion or representations with respect to such matters are erroneous.

Where any Person is required to make, give or execute two or more applications, requests, consents, certificates, statements, opinions or other instruments under this Agreement, they may, but need not, be consolidated and form one instrument.

Section 6.05 Maintenance of Office or Agency. So long as Units are authorized for issuance pursuant to this Agreement or are Outstanding hereunder, the Company will maintain an office or agency where Units may be presented or surrendered for delivery, where Units may be surrendered for registration of transfer or exchange and where notices and demands to or upon the Company in respect of Units and this Agreement may be served. The Company hereby initially designates the Units Trustee for each of said purposes. The Company will give prompt

22

written notice to the Units Trustee of the location, and any change in the location, of such office or agency. If at any time the Company shall fail to maintain any such required office or agency or shall fail to furnish the Units Trustee with the name and address thereof, such presentations, surrenders, notices and demands may be made or served at the Corporate Trust Office of the Units Trustee, and the Company hereby appoints the Units Trustee as its agent to receive all such presentations, surrenders, notices and demands.

The Company may also from time to time designate one or more other offices or agencies where Units may be presented or surrendered for any or all such purposes and may from time to time rescind such designations; provided, however, that no such designation or rescission shall in any manner relieve the Company of its obligations to maintain offices or agencies provided for in this Section 6.05. The Company will give prompt written notice to the Units Trustee of any such designation or rescission and of any change in the location of any such other office or agency.

Section 6.06 Notices, Etc. Any request, demand, authorization, direction, notice, consent, waiver or act of Holders or other document provided or permitted by this Agreement to be made upon, given or furnished to, or filed with:

Section 6.07 Notices to Holders. Any notice or communication mailed to a Holder of Units shall be mailed to the Holder at the Holder’s address as it appears on the Units Register and shall be sufficiently given if so mailed within the time prescribed. Any notice to the owners of a beneficial interest in a Global Unit shall be distributed through the Depositary in accordance with the procedures of the Depositary. Communications to owners shall be deemed to be effective at the time of dispatch to the Depositary. Failure to provide a notice or communication to a Holder or owner of a beneficial interest in a Global Unit or any defect in it shall not affect its sufficiency with respect to other Holders or owners of a beneficial interest in a Global Unit. If a notice or communication is provided in the manner provided above, it is duly given, whether or not the intended recipient actually receives it. Any notice received by the Units Trustee in respect of the Attached Common Shares or Attached Notes shall be transmitted by the Unit Trustee to the Holders as provided in this Section 6.07.

Section 6.13 Counterparts.
