Article II

FORM OF RECEIPTS, DEPOSIT OF SERIES B PREFERRED STOCK, EXECUTION AND DELIVERY, TRANSFER, SURRENDER AND REDEMPTION OF RECEIPTS

Section 2.1 Form and Transfer of Receipts.

The definitive Receipts shall be substantially in the form set forth in Exhibit A attached to this Deposit Agreement, with appropriate insertions, modifications and omissions, as hereinafter provided. Pending the preparation of definitive Receipts, the Depositary, upon the written order of the Corporation delivered in compliance with Section 2.2, shall execute and deliver temporary Receipts which may be printed, lithographed, typewritten, mimeographed or otherwise substantially of the tenor of the definitive Receipts in lieu of which they are issued and with such appropriate insertions, omissions, substitutions and other variations, with the Corporation’s prior approval, as the Persons executing such Receipts may reasonably determine necessary, as evidenced by their execution of such Receipts. If temporary Receipts are issued, the Corporation and the Depositary will cause definitive Receipts to be prepared without unreasonable delay. After the preparation of definitive Receipts, the temporary Receipts shall be exchangeable for definitive Receipts upon surrender of the temporary Receipts at an office described in the penultimate paragraph of Section 2.2, without charge to the Holder. Upon surrender for cancellation of any one or more temporary Receipts, the Depositary shall execute and deliver in exchange therefor definitive Receipts representing the same number of Depositary Shares as represented by the surrendered temporary Receipt or Receipts. Such exchange shall be made at the Corporation’s expense and without any charge therefor. Until so exchanged, the temporary Receipts shall in all respects be entitled to the same benefits under this Deposit Agreement, and with respect to the Series B Preferred Stock, as definitive Receipts.

Any Receipt to be executed by the Depositary pursuant to this Deposit Agreement shall be executed by the manual, electronic or facsimile signature of a duly authorized officer of the Depositary. No Receipt shall be entitled to any benefits under this Deposit Agreement or be valid or obligatory for any purpose unless it shall have been executed manually, electronically or by the facsimile signature of a duly authorized officer of the Depositary or, if a Registrar for the Receipts (other than the Depositary) shall have been appointed, by the manual, electronic or facsimile signature of a duly authorized officer of the Depositary and countersigned by the manual, electronic or facsimile signature by a duly authorized officer of such Registrar. The Depositary shall record on its books each Receipt so signed and delivered as hereinafter provided. Receipts bearing the manual, electronic or facsimile signature of a duly authorized signatory of the Depositary who was at such time a proper signatory of the Depositary shall bind the Depositary, notwithstanding that such signatory ceased to hold such office prior to the execution and delivery of such Receipts by the Registrar or did not hold such office on the date of issuance of such Receipts.

Receipts shall be in denominations of any number of whole Depositary Shares. All Receipts shall be dated the date of their issuance.

Receipts may be endorsed with or have incorporated in the text thereof such legends or recitals or changes not inconsistent with the provisions of this Deposit Agreement all as may be (i) reasonably required by the Depositary and approved by the Corporation, (ii) required to comply with any applicable law or any regulation thereunder or with the rules and regulations of any securities exchange upon which the Series B Preferred Stock, the Depositary Shares or the Receipts may be listed or to conform with any usage with respect thereto, or (iii) to indicate any special limitations or restrictions to which any particular Receipt is subject.

4

Title to Depositary Shares evidenced by a Receipt which is properly endorsed or accompanied by a properly executed instrument of transfer, shall be transferable by delivery of such Receipt with the same effect as if such Receipt were a negotiable instrument; provided, however, that until transfer of any particular Receipt shall be registered on the books of the Depositary as provided in Section 2.3, the Depositary may, notwithstanding any notice to the contrary, treat the Record Holder thereof at such time as the absolute owner thereof for the purpose of determining the Person entitled to distributions of dividends or other distributions or to any notice provided for in this Deposit Agreement and for all other purposes.

The Corporation shall have made a written request prior to the date hereof requesting that the Series B Preferred Stock and the associated Depositary Shares be set aside and reserved for issuance. On the date hereof, the Corporation shall provide the Depositary with an opinion of counsel (which may be an opinion of internal counsel) stating that: (i) all shares of Series B Preferred Stock have been registered under the Securities Act of 1933, as amended; (ii) all shares of Series B Preferred Stock have been validly issued and are fully paid and non-assessable; and (iii) upon due issuance by the Depositary of the Receipts evidencing the Depositary Shares against the deposit of Series B Preferred Stock in accordance with the provisions of this Deposit Agreement and payment therefor, the Receipts will entitle the persons in whose names the Receipts are registered to the rights specified therein and in this Deposit Agreement, subject to bankruptcy, insolvency, fraudulent transfer, reorganization, moratorium and similar laws of general applicability relating to or affecting creditors’ rights and to general equity principles.

Subject to the terms and conditions of this Deposit Agreement, the Corporation may from time to time deposit shares of Series B Preferred Stock under this Deposit Agreement by delivery to the Depositary, including via direct registration for shares of Series B Preferred Stock in uncertificated form, for such shares of Series B Preferred Stock to be deposited (or in such other manner as may be agreed to by the Corporation and the Depositary), properly endorsed or accompanied, if required by the Depositary, by a duly executed instrument of transfer or endorsement in a form reasonably satisfactory to the Depositary, together with (i) all such certifications as may be reasonably required by the Depositary pursuant to this Deposit Agreement and (ii) an instruction letter from the Corporation authorizing the Depositary to register such shares of the Series B Preferred Stock in uncertificated form by direct registration, each in a form satisfactory to the Depositary, together with an instruction letter of the Corporation directing the Depositary to execute and deliver to, or upon the written order of, the Person or Persons stated in such instruction letter a Receipt or Receipts evidencing in the aggregate the number of Depositary Shares representing such deposited shares of Series B Preferred Stock.

The shares of Series B Preferred Stock that are deposited pursuant to this Deposit Agreement shall be held by the Depositary at the Depositary’s Office or at such other place or places as the Depositary shall determine. The Depositary shall not lend any shares of Series B Preferred Stock deposited hereunder.

5

Upon receipt by the Depositary of shares of Series B Preferred Stock to be deposited in accordance with the provisions of this Section 2.2, together with the other documents required as specified above, and upon recordation of the shares of Series B Preferred Stock on the books of the Corporation (or its duly appointed transfer agent) in the name of the Depositary (or its nominee), the Depositary, subject to the terms and conditions of this Deposit Agreement, shall execute and deliver to or upon the order of the Person or Persons named in the instruction letter delivered to the Depositary referred to in the first paragraph of this Section 2.2, a Receipt or Receipts evidencing in the aggregate the number of Depositary Shares representing the shares of Series B Preferred Stock so deposited and registered in such name or names as may be requested by such Person or Persons. The Depositary shall execute and deliver such Receipt or Receipts at the Depositary’s Office or such other offices, if any, as the Depositary may designate. Delivery at other offices shall be at the risk and expense of the Person requesting such delivery.

The Corporation hereby appoints Computershare as transfer agent and as registrar in respect of the Series B Preferred Stock deposited with the Depositary hereunder, and Computershare hereby accepts the appointments on the express terms and conditions set forth in this Deposit Agreement. With respect to the appointments of Computershare as transfer agent and as registrar in respect of the Series B Preferred Stock, Computershare shall be entitled to the same rights, indemnities, immunities and benefits as the Depositary hereunder as if explicitly named in each such provision.

Subject to the terms and conditions of this Deposit Agreement, the Transfer Agent shall register on its books from time to time transfers of Receipts upon any surrender thereof by the Holder in person or by duly authorized attorney, properly endorsed or accompanied by a properly executed instrument of transfer and appropriate evidence of authority which shall include a signature guarantee from an eligible guarantor institution participating in a signature guarantee program approved by the Securities Transfer Association (a “Signature Guarantee”), and any other reasonable evidence of authority that may be required by the Transfer Agent, together with (if applicable) evidence of the payment by the applicable party of any taxes or charges as may be required by law. Thereupon, the Depositary shall execute a new Receipt or Receipts evidencing the same aggregate number of Depositary Shares as those evidenced by the Receipt or Receipts surrendered and deliver such new Receipt or Receipts to or upon the order of the Person entitled thereto.

Upon surrender of a Receipt or Receipts at the Depositary’s Office or at such other offices as it may designate for the purpose of effecting a split-up or combination of such Receipt or Receipts, and subject to the terms and conditions of this Deposit Agreement, the Depositary shall execute a new Receipt or Receipts in the authorized denomination or denominations requested, evidencing the aggregate number of Depositary Shares evidenced by the Receipt or Receipts surrendered, and shall deliver such new Receipt or Receipts to or upon the order of the Holder of the Receipt or Receipts so surrendered.

6

Any Holder of a Receipt or Receipts may withdraw the number of whole shares of Series B Preferred Stock (and all money and other property, if any, represented thereby) by surrendering such Receipt or Receipts at the Depositary’s Office or at such other offices as the Depositary may designate for such withdrawals; provided, however that a Holder of a Receipt may not withdraw such whole shares of Series B Preferred Stock (or money and other property, if any, represented thereby) which has previously been called for redemption. After such surrender and upon the receipt of written instructions from the Holder of such Receipt or Receipts, without unreasonable delay, the Depositary shall deliver to such Holder, or to the Person or Persons designated by such Holder as hereinafter provided, the number of whole shares of Series B Preferred Stock (and all money and other property, if any), represented by such Receipt so surrendered for withdrawal, but Holders of such whole shares of Series B Preferred Stock will not thereafter be entitled to deposit such shares of Series B Preferred Stock hereunder or to receive a Receipt evidencing Depositary Shares therefor. If a Receipt delivered by the Holder to the Depositary in connection with such withdrawal shall evidence a number of Depositary Shares in excess of the number of Depositary Shares representing the number of whole shares of Series B Preferred Stock to be withdrawn, the Depositary shall at the same time, in addition to such number of whole shares of Series B Preferred Stock and such money and other property, if any, to be so withdrawn, deliver to such Holder, or subject to Section 2.3 upon the written order of such Holder, a new Receipt evidencing such excess number of Depositary Shares.

In no event will fractional shares of Series B Preferred Stock (or any cash payment in lieu thereof) be delivered by the Depositary. Delivery of the Series B Preferred Stock and money and other property, if any, being withdrawn may be made by the delivery of such certificates, documents of title and other instruments as the Depositary may deem appropriate.

If the Series B Preferred Stock and the money and other property, if any, being withdrawn are to be delivered to a Person or Persons other than the Record Holder of the related Receipt or Receipts being surrendered for withdrawal of such Series B Preferred Stock, such Holder shall execute and deliver to the Depositary a written order so directing the Depositary, and the Depositary may require that the Receipt or Receipts surrendered by such Holder for withdrawal of such shares of Series B Preferred Stock be properly endorsed in blank or accompanied by a properly executed instrument of transfer in blank.

Delivery of the Series B Preferred Stock and the money and other property, if any, represented by Receipts surrendered for withdrawal shall be made by the Depositary at the Depositary’s Office, except that, at the request, risk and expense of the Holder surrendering such Receipt or Receipts and for the account of the Holder thereof, such delivery may be made at such other place as may be designated by such Holder.

As a condition precedent to the execution and delivery, registration of transfer, split-up, combination, surrender or exchange of any Receipt, the Depositary, any of the Depositary’s Agents or the Corporation may require (i) payment to it of a sum sufficient for the payment (or, in the event that the Depositary or the Corporation shall have made such payment, the reimbursement to it) of any charges, taxes or expenses payable by the Holder of a Receipt pursuant to Section 5.8 (including any such tax or charge with respect to any shares of Series B

7

Preferred Stock being deposited or withdrawn or any charges or expense pursuant to Section 3.2), (ii) the production of evidence satisfactory to it as to the identity and genuineness of any signature which evidence shall include a Signature Guarantee, and any other reasonable evidence of authority that may be required by the Depositary, and (iii) compliance with such additional requirements, if any, as the Depositary or the Corporation may reasonably establish consistent with the provisions of this Deposit Agreement and/or applicable law.

The deposit of shares of Series B Preferred Stock may be refused, the delivery of Receipts against such shares of Series B Preferred Stock may be suspended, the registration of transfer of Receipts may be refused and the registration of transfer, surrender or exchange of outstanding Receipts may be suspended (i) during any period when the register of stockholders of the Corporation is closed or (ii) if any such action is deemed necessary or advisable by the Depositary, any of the Depositary’s Agents or the Corporation at any time or from time to time because of any requirement of law or of any government or governmental body or commission or under any provision of this Deposit Agreement.

In case any Receipt shall be mutilated, destroyed, lost or stolen, the Depositary in its discretion may execute and deliver a Receipt of like form and tenor in exchange and substitution for such mutilated Receipt, or in lieu of and in substitution for such destroyed, lost or stolen Receipt, upon (i) the filing by the Holder thereof with the Depositary of evidence satisfactory to the Depositary of such destruction or loss or theft of such Receipt, of the authenticity thereof and of such Holder’s ownership thereof and (ii) the Holder thereof furnishing the Depositary with an affidavit and an indemnity or bond satisfactory to the Depositary. Such Holder shall also comply with such other reasonable regulations and pay such other reasonable charges as the Depositary may prescribe and as required by Section 8-405 of the Uniform Commercial Code in effect in the State of New York.

All Receipts surrendered to the Depositary or any Depositary’s Agent shall be cancelled by the Depositary. Except as prohibited by applicable law or regulation, the Depositary is authorized and directed to destroy all Receipts so cancelled.

Whenever the Corporation shall be permitted and shall elect to redeem shares of Series B Preferred Stock in accordance with the terms of the Certificate of Designations, it shall (unless otherwise agreed to in writing with the Depositary) give or cause to be given to the Depositary, not less than 35 days and not more than 60 days prior to the Redemption Date (as defined below), notice of the date of such proposed redemption of Series B Preferred Stock and of the number of such shares held by the Depositary to be so redeemed and the applicable Redemption Price, which notice shall be accompanied by a certificate from the Corporation stating that such redemption of shares of Series B Preferred Stock is in accordance with the provisions of the Certificate of Designations. On the applicable Redemption Date, provided that the Corporation shall then have paid or caused to be paid in full to the Depositary the

8

Redemption Price of the Series B Preferred Stock to be redeemed, in accordance with the provisions of the Certificate of Designations, the Depositary shall redeem the number of Depositary Shares representing such shares of Series B Preferred Stock. The Depositary shall transmit notice of the Corporation’s redemption of shares of Series B Preferred Stock and the proposed simultaneous redemption of the number of Depositary Shares representing such shares of the Series B Preferred Stock to be redeemed by first-class mail, postage prepaid, or by such other method approved by the Depositary (in its reasonable discretion), in either case not less than 30 days and not more than 60 days prior to the date fixed for redemption of such shares of Series B Preferred Stock and Depositary Shares (the “Redemption Date”), to the Record Holders of the Receipts evidencing the Depositary Shares to be so redeemed at the addresses of such Holders as they appear on the records of the Depositary; but neither failure to mail or transmit any such notice of redemption of Depositary Shares to one or more such Holders nor any defect in any notice of redemption of Depositary Shares to one or more such Holders shall affect the sufficiency of the proceedings for redemption as to the other Holders. Each such notice shall be prepared by the Corporation and shall state: (i) the Redemption Date; (ii) the number of Depositary Shares to be redeemed and, if less than all the Depositary Shares held by any such Holder are to be redeemed, the number of such Depositary Shares held by such Holder to be so redeemed; (iii) the applicable redemption price; (iv) the place or places where Receipts evidencing such Depositary Shares are to be surrendered for payment of the redemption price; and (v) that dividends in respect of the Series B Preferred Stock represented by such Depositary Shares to be redeemed will cease to accrue on such Redemption Date. In case less than all the outstanding Depositary Shares are to be redeemed, the Depositary Shares to be so redeemed shall be selected either pro rata or by lot or in such other manner proportionate and applicable to the manner in which shares of the Series B Preferred Stock are redeemed as determined to be fair and equitable by the board of directors of the Corporation or a duly authorized committee thereof.

Notice having been mailed or transmitted by the Depositary as aforesaid, from and after the Redemption Date (unless the Corporation shall have failed to provide the funds necessary to redeem the Series B Preferred Stock evidenced by the Depositary Shares called for redemption) (i) dividends on the shares of Series B Preferred Stock so called for redemption shall cease to accrue from and after such date, (ii) the Depositary Shares being redeemed from such proceeds shall be deemed no longer to be outstanding, (iii) all rights of the Holders of Receipts evidencing such Depositary Shares (except the right to receive the applicable redemption price) shall, to the extent of such Depositary Shares, cease and terminate, and (iv) upon surrender in accordance with such redemption notice of the Receipts evidencing any such Depositary Shares called for redemption (properly endorsed or assigned for transfer, if the Depositary or applicable law shall so require), such Depositary Shares shall be redeemed by the Depositary at a redemption price per Depositary Share equal to 1/40^th of the Redemption Price per share of Series B Preferred Stock so redeemed.

If fewer than all of the Depositary Shares evidenced by a Receipt are called for redemption, the Depositary will deliver to the Holder of such Receipt upon its surrender to the Depositary, together with the applicable redemption price for all of the Depositary Shares redeemed, a new Receipt evidencing the Depositary Shares evidenced by such prior Receipt and not called for redemption.

9

All funds received by Computershare under this Deposit Agreement that are to be distributed or applied by Computershare in the performance of services (the “Funds”) shall be held by Computershare as agent for the Corporation and deposited in one or more bank accounts to be maintained by Computershare in its name as agent for the Corporation. Until paid pursuant to this Deposit Agreement, Computershare may hold or invest the Funds through such accounts in: (i) obligations of, or guaranteed by, the United States of America, (ii) commercial paper obligations rated A-1 or P-1 or better by Standard & Poor’s Corporation (“S&P”) or Moody’s Investors Service, Inc. (“Moody’s”), respectively, (iii) money market funds that comply with Rule 2a-7 of the Investment Company Act of 1940, or (iv) demand deposit accounts, short-term certificates of deposit, bank repurchase agreements or bankers’ acceptances, of commercial banks with Tier 1 capital exceeding $1 billion or with an average rating above investment grade by S&P (LT Local Issuer Credit Rating), Moody’s (Long Term Rating) and Fitch Ratings, Inc. (LT Issuer Default Rating) (each as reported by Bloomberg Finance L.P.). Computershare shall have no responsibility or liability for any diminution of the Funds that may result from any deposit or investment made by Computershare in accordance with this paragraph, including any losses resulting from a default by any bank, financial institution or other third party. Computershare may from time to time receive interest, dividends or other earnings in connection with such deposits or investments. Computershare shall not be obligated to pay such interest, dividends or earnings to the Corporation, any holder or any other party.

If the Corporation shall determine in a writing delivered to the Depositary that the Receipts are to be issued in whole or in part in the form of one or more Global Registered Receipts, then the Depositary shall, in accordance with the other provisions of this Deposit Agreement, execute and deliver one or more Global Registered Receipts which (i) shall represent, and shall be denominated in an amount equal to the aggregate principal amount of, the Receipts to be represented by such Global Registered Receipt or Receipts and (ii) shall be registered in the name of the Global Receipt Depository therefor or its nominee.

Notwithstanding any other provision of this Deposit Agreement to the contrary, unless otherwise provided in the Global Registered Receipt, a Global Registered Receipt may only be transferred in whole and only by the applicable Global Receipt Depository for such Global Registered Receipt to a nominee of such Global Receipt Depository, or by a nominee of such Global Receipt Depository to such Global Receipt Depository or another nominee of such Global Receipt Depository, or by such Global Receipt Depository or any such nominee to a successor Global Receipt Depository for such Global Registered Receipt selected or approved by the Corporation or to a nominee of such successor Global Receipt Depository. Except as provided below, owners solely of beneficial interests in a Global Registered Receipt shall not be entitled to receive physical delivery of the Receipts represented by such Global Registered Receipt. Neither any such beneficial owner nor any direct or indirect participant of a Global Receipt Depository shall have any rights under this Deposit Agreement with respect to any Global Registered Receipt held on their behalf by a Global Receipt Depository and such Global Receipt Depository may be treated by the Corporation, the Depositary and any director, officer, employee or agent of the Corporation or the Depositary as the Holder of such Global Registered

10

Receipt for all purposes whatsoever. Unless and until definitive Receipts are delivered to the owners of the beneficial interests in a Global Registered Receipt, (1) the applicable Global Receipt Depository will make book-entry transfers among its participants and receive and transmit all payments and distributions in respect of the Global Registered Receipts to such participants, in each case, in accordance with its applicable procedures and arrangements, and (2) whenever any notice, payment or other communication to the Holders of Global Registered Receipts is required under this Deposit Agreement, the Corporation and the Depositary shall give all such notices, payments and communications specified herein to be given to such Holders to the applicable Global Receipt Depository.

If an Exchange Event has occurred with respect to any Global Registered Receipt, then, in any such event, the Depositary shall, upon receipt of a written order from the Corporation for the execution and delivery of individual definitive registered Receipts in exchange for such Global Registered Receipt, shall execute and deliver, individual definitive registered Receipts, in authorized denominations and of like tenor and terms in an aggregate principal amount equal to the principal amount of the Global Registered Receipt in exchange for such Global Registered Receipt.

Definitive registered Receipts issued in exchange for a Global Registered Receipt pursuant to this Section 2.10 shall be registered in such names and in such authorized denominations as the Global Receipt Depository for such Global Registered Receipt, pursuant to instructions from its participants, shall instruct the Depositary in writing. The Depositary shall deliver such Receipts to the Persons in whose names such Receipts are so registered.

Notwithstanding anything to the contrary in this Deposit Agreement, should the Corporation determine that the Receipts should be issued as a Global Registered Receipt, the parties hereto shall comply with the terms of any Letter of Representations.

Article III

CERTAIN OBLIGATIONS OF HOLDERS OF RECEIPTS AND THE CORPORATION

Any Holder of a Receipt may be required from time to time to file such proof of residence, or other matters or other information, to execute such certificates and to make such representations and warranties as the Depositary or the Corporation may reasonably deem necessary or proper. The Depositary or the Corporation may withhold the delivery, or delay the registration of transfer or redemption, of any Receipt or the withdrawal of shares of Series B Preferred Stock represented by the Depositary Shares and evidenced by a Receipt or withhold or delay the distribution of any dividend or other distribution or the sale of any rights or of the proceeds thereof until such proof or other information is filed or such certificates are executed or such representations and warranties are made.

11

Holders of Receipts shall be obligated to make payments to Computershare, as service provider on behalf of the Depositary, of certain taxes, charges and expenses, as provided in Section 5.8. Registration of transfer of any Receipt or any withdrawal of shares of Series B Preferred Stock and all money or other property, if any, represented by the Depositary Shares evidenced by any Receipt may be refused until any such payment due is made, and any dividends, interest payments or other distributions may be withheld or any part of or all the Series B Preferred Stock or other property represented by the Depositary Shares evidenced by any such Receipt and not theretofore sold may be sold for the account of the Holder thereof (after attempting by reasonable means to notify such Holder prior to such sale), and such dividends, interest payments or other distributions or the proceeds of any such sale may be applied to any payment of such charges or expenses, with the Holder of such Receipt remaining liable for any deficiency.

The Corporation hereby represents and warrants that the Series B Preferred Stock, when issued, will be duly authorized, validly issued, fully paid and non-assessable. Such representation and warranty shall survive the deposit of the Series B Preferred Stock and the issuance of the related Receipts.

The Corporation hereby represents and warrants that the Depositary Shares, when issued, will represent legal and valid interests in the Series B Preferred Stock. Such representation and warranty shall survive the deposit of the Series B Preferred Stock and the related issuance of the Receipts.

Article IV

THE DEPOSITED SECURITIES; NOTICES

Whenever the Depositary (through the account of Computershare acting as dividend distributing agent for the Depositary pursuant to the Intercompany Agreement) shall receive any cash dividend or other cash distribution on the Series B Preferred Stock, the Depositary shall cause Computershare, subject to Section 3.1 and Section 3.2, to distribute to Record Holders of Receipts on the record date fixed pursuant to Section 4.4 such amounts of such dividend or distribution as are, as nearly as practicable, in proportion to the respective numbers of Depositary Shares evidenced by the Receipts held by such Holders; provided, however, that in case the Corporation or the Depositary (or Computershare acting as the dividend distributing agent for the Depositary) shall be required to withhold and shall withhold from any cash dividend or other cash distribution in respect of the Series B Preferred Stock an amount on account of taxes, the amount made available for distribution or distributed in respect of Depositary Shares shall be reduced accordingly. The Depositary shall cause Computershare to distribute or make available for distribution, as the case may be, only such amount, however, as can be distributed without attributing to any Holder of Receipts a fraction of one cent, and any balance not so distributable shall be held by Computershare (without liability for interest thereon), as service provider for the Depositary, and shall be added to and be treated as part of

12

the next sum received by the Depositary (through the account of Computershare acting as dividend distributing agent for the Depositary pursuant to the Intercompany Agreement) for distribution to Record Holders of Receipts then outstanding. Each Holder of a Receipt shall provide the Depositary with its certified tax identification number on a properly completed Form W-8 or W-9, as may be applicable. Each Holder of a Receipt acknowledges that, in the event of non-compliance with the preceding sentence, the Internal Revenue Code of 1986, as amended, may require withholding by the Depositary (or Computershare acting as the dividend distributing agent for the Depositary) of a portion of any of the distributions to be made hereunder.

Whenever the Depositary shall receive any distribution other than cash, rights, preferences or privileges upon the Series B Preferred Stock, the Depositary shall, subject to Section 3.1 and Section 3.2, distribute to Record Holders of Receipts on the record date fixed pursuant to Section 4.4 such amounts of the securities or property received by it as the Corporation shall reasonably direct. If in the opinion of the Corporation, in consultation with the Depositary, such distribution cannot be made proportionately among such Record Holders, or if for any other reason (including any requirement that the Corporation or the Depositary withhold an amount on account of taxes or charges) such distribution shall not be feasible, the Corporation, in its discretion, may adopt such method as it deems equitable and practicable for the purpose of effecting such distribution, including the sale (at public or private sale) of the securities or property thus received, or any part thereof, in a commercially reasonable manner. The net proceeds of any such sale shall, subject to Section 3.1 and Section 3.2, be distributed or made available for distribution, as the case may be, by the Depositary to Record Holders of Receipts as provided by Section 4.1 in the case of a distribution received in cash. The Corporation shall not make any distribution of securities or property (other than cash) to the Depositary and the Depositary shall not make any distribution of securities or property (other than cash) to the Holders of Receipts unless such securities or property have been registered under the Securities Act or the Corporation shall have provided an opinion of counsel as set forth in Section 2.1 above, dated as of or prior to the date of such distribution, stating that such securities or property do not need to be registered in connection with such distributions.

If the Corporation shall at any time offer or cause to be offered to the Persons in whose names the Series B Preferred Stock is recorded on the books of the Corporation any rights, preferences or privileges to subscribe for or to purchase any securities or any rights, preferences or privileges of any other nature, such rights, preferences or privileges shall in each such instance be made available by the Depositary to the Record Holders of Receipts in such manner as the Corporation shall reasonably direct; provided, however, that (i) if at the time of issue or offer of any such rights, preferences or privileges the Corporation determines that it is not lawful or (after consultation with the Depositary) not feasible to make such rights, preferences or privileges available to Holders of Receipts by the issue of warrants or otherwise, or (ii) if and to the extent so instructed by Holders of Receipts who do not desire to exercise such rights, preferences or privileges, then the Corporation, in its discretion, may, if applicable laws or the terms of such rights, preferences or privileges permit such transfer, sell such rights,

13

preferences or privileges at public or private sale, at such place or places and upon such terms as it may deem proper. The net proceeds of any such sale shall be delivered to the Depositary and, subject to Section 3.1 and Section 3.2, be distributed by the Depositary to the Record Holders of Receipts entitled thereto as provided by Section 4.1 in the case of a distribution received in cash. In no event shall the Depositary make available to the Holders of Receipts any right, preference or privilege to subscribe for or to purchase any securities unless such securities have been registered under the Securities Act or the Corporation shall have provided an opinion of counsel stating that such securities do not need to be registered in connection with such distributions.

The Corporation shall notify the Depositary whether any other action under the laws of any jurisdiction or any governmental or administrative authorization, consent or permit is required in order for such rights, preferences or privileges to be made available to Holders of Receipts, and the Corporation agrees with the Depositary that the Corporation will use its reasonable best efforts to take such action or obtain such authorization, consent or permit sufficiently in advance of the expiration of such rights, preferences or privileges to enable such Holders to exercise such rights, preferences or privileges.

Whenever any cash dividend or other cash distribution shall become payable or any distribution other than cash shall be made, or if rights, preferences or privileges shall at any time be offered, with respect to the Series B Preferred Stock, or whenever the Depositary shall receive notice of any meeting at which Holders of the Series B Preferred Stock are entitled to vote or of which Holders of the Series B Preferred Stock are entitled to notice, or whenever the Depositary and the Corporation shall decide it is appropriate, the Depositary shall in each such instance fix a record date (which shall be the same date as the record date fixed by the Corporation with respect to or otherwise in accordance with the terms of the Series B Preferred Stock) for the determination of the Holders of Receipts who shall be entitled to receive such dividend, distribution, rights, preferences or privileges or the net proceeds of the sale thereof, or to give instructions for the exercise of voting rights at any such meeting, or who shall be entitled to notice of such meeting or for any other appropriate reasons.

Subject to the Certificate of Designations, upon receipt of notice from the Corporation of any meeting at which the Holders of the Series B Preferred Stock are entitled to vote, the Depositary shall, as soon as practicable thereafter, transmit to the Record Holders of Receipts, as determined on the record date set forth in Section 4.4, a notice prepared by the Corporation which shall contain (i) such information as is contained in such notice of meeting, (ii) a statement that the Holders of Receipts at the close of business on a specified record date fixed pursuant to Section 4.4 may, subject to any applicable restrictions, instruct the Depositary as to the exercise of the voting rights pertaining to the shares of Series B Preferred Stock represented by their respective Depositary Shares (including an express indication that instructions may be given to the Depositary to give a discretionary proxy to a Person designated by the Corporation), and (iii) a brief statement as to the manner in which such instructions may be given. Upon the written request of the Holders of Receipts on the relevant record date, the Depositary shall endeavor insofar as practicable to vote or cause to be voted, in accordance with

14

the instructions set forth in such requests, the maximum number of whole shares of Series B Preferred Stock represented by the Depositary Shares evidenced by all Receipts as to which any particular voting instructions are received. The Corporation hereby agrees to take all reasonable action which may be deemed necessary by the Depositary in order to enable the Depositary to vote such Series B Preferred Stock or cause such Series B Preferred Stock to be voted. In the absence of specific instructions from the Holder of a Receipt, the Depositary will not vote (but, at its discretion, may appear at any meeting with respect to such Series B Preferred Stock unless directed to the contrary by the Holders of all the Receipts) to the extent of the Series B Preferred Stock represented by the Depositary Shares evidenced by such Receipt.

Upon any change in par or stated value, split-up, combination or any other reclassification of the Series B Preferred Stock, subject to the Certificate of Designations, or upon any recapitalization, reorganization, merger or consolidation affecting the Corporation or to which it is a party, the Depositary shall, upon the written instructions of the Corporation setting forth any adjustment, (i) make such adjustments as are certified by the Corporation in the fraction of an interest represented by one Depositary Share in one share of Series B Preferred Stock and in the ratio of the redemption price per Depositary Share to the Redemption Price per share of Series B Preferred Stock, in each case as may be necessary fully to reflect the effects of such change in par or stated value, split-up, combination or other reclassification of the Series B Preferred Stock, or of such recapitalization, reorganization, merger or consolidation and (ii) treat any securities or property (including cash) which shall be received by the Depositary in exchange for or upon conversion of or in respect of the Series B Preferred Stock as new deposited securities or property so received in exchange for or upon conversion or in respect of such Series B Preferred Stock. In any such case the Depositary may in its discretion, with the approval of the Corporation, execute and deliver additional Receipts or may call for the surrender of all outstanding Receipts to be exchanged for new Receipts specifically describing such new deposited securities or property. Anything to the contrary herein notwithstanding, Holders of Receipts shall have the right from and after the effective date of any such change in par or stated value, split-up, combination or other reclassification of the Series B Preferred Stock or any such recapitalization, reorganization, merger or consolidation to surrender such Receipts to the Depositary with instructions to convert, exchange or surrender the Series B Preferred Stock represented thereby only into or for, as the case may be, the kind and amount of shares and other securities and property and cash into which the Series B Preferred Stock represented by such Receipts might have been converted or for which such Series B Preferred Stock might have been exchanged or surrendered immediately prior to the effective date of such transaction.

The Depositary shall furnish to Holders of Receipts any reports and communications received from the Corporation which are received by the Depositary and which the Corporation is required to furnish to the Holders of the Series B Preferred Stock.

15

Reasonably promptly upon request from time to time by the Corporation, at the sole expense of the Corporation, the Depositary shall furnish to it a list, as of the most recent practicable date, of the names, addresses and holdings of Depositary Shares of all registered Holders of Receipts.

Article V

THE DEPOSITARY, THE DEPOSITARY’S AGENTS, THE REGISTRAR AND THE CORPORATION

The Corporation hereby appoints Computershare to act as Depositary in accordance with the terms and conditions hereof, and Computershare accepts this appointment. Depositary is engaged in an independent business and will perform its obligations under this Deposit Agreement as an agent of the Corporation.

Upon execution of this Deposit Agreement, the Depositary shall maintain at the Depositary’s Office, facilities for the execution and delivery, registration and registration of transfer, surrender and exchange of Receipts, and at the offices of the Depositary’s Agents, if any, facilities for the delivery, registration of transfer, surrender and exchange of Receipts, all in accordance with the provisions of this Deposit Agreement.

The Depositary shall keep books at the Depositary’s Office for the registration and registration of transfer of Receipts, which books at all reasonable times during regular business hours shall be open for inspection by the Record Holders of Receipts; provided that any such Holder requesting to exercise such right shall certify to the Depositary that such inspection shall be for a proper purpose reasonably related to such Person’s interest as an owner of Depositary Shares evidenced by the Receipts.

The Depositary may close such books, at any time or from time to time, when deemed necessary or advisable by it in connection with the performance of its duties hereunder.

The Depositary may, with the approval of the Corporation, appoint a Registrar for registration of the Receipts or the Depositary Shares evidenced thereby. If the Receipts or the Depositary Shares evidenced thereby or the Series B Preferred Stock represented by such Depositary Shares shall be listed on one or more national securities exchanges, the Depositary will appoint a Registrar (acceptable to the Corporation) for registration of the Receipts or Depositary Shares in accordance with any requirements of such exchange. Such Registrar (which may be the Depositary if so permitted by the requirements of any such exchange) may be removed and a substitute registrar appointed by the Depositary upon the request or with the approval of the Corporation. If the Receipts, Depositary Shares or Series B Preferred Stock are listed on one or more other securities exchanges, the Depositary will, at the request of the Corporation, arrange such facilities for the delivery, registration, registration of transfer, surrender and exchange of the Receipts, Depositary Shares or Series B Preferred Stock as may be required by law or applicable securities exchange regulation.

16

Neither the Depositary nor any Depositary’s Agent nor any Registrar nor any Transfer Agent nor the Corporation shall incur any liability to any Holder of Receipt if by reason of any provision of any present or future law, or regulation thereunder, of the United States of America or of any other governmental authority or, in the case of the Depositary, the Depositary’s Agent or the Registrar or any Transfer Agent, by reason of any provision, present or future, of the Corporation’s Restated Articles of Incorporation (including the Certificate of Designations) or by reason of any act of God or war or other circumstance beyond the control of the relevant party, the Depositary, the Depositary’s Agent, the Registrar, the Transfer Agent or the Corporation shall be prevented or forbidden from, or subjected to any penalty on account of, doing or performing any act or thing which the terms of this Deposit Agreement provide shall be done or performed; nor shall the Depositary, any Depositary’s Agent, any Registrar, any Transfer Agent or the Corporation incur liability to any Holder of a Receipt (i) by reason of any nonperformance or delay, caused as aforesaid, in the performance of any act or thing which the terms of this Deposit Agreement shall provide shall or may be done or performed, or (ii) by reason of any exercise of, or failure to exercise, any discretion provided for in this Deposit Agreement except as otherwise explicitly set forth in this Deposit Agreement.

Neither the Depositary nor any Depositary’s Agent nor any Registrar nor the Transfer Agent nor the Corporation assumes any obligation or shall be subject to any liability under this Deposit Agreement to Holders of Receipts or any other Person other than for its gross negligence, willful misconduct or bad faith (each as determined by a final non-appealable judgment of a court of competent jurisdiction). Notwithstanding anything in this Deposit Agreement to the contrary, excluding the Depositary’s fraud, recklessness, willful misconduct or bad faith (each as determined by a final non-appealable judgment of a court of competent jurisdiction), the Depositary’s, any Depositary’s Agent, Registrar’s or Transfer Agent’s aggregate liability under this Deposit Agreement with respect to, arising from or arising in connection with this Deposit Agreement, or from all services provided or omitted to be provided under this Deposit Agreement, whether in contract, tort, or otherwise, is limited to, and shall not exceed, the amounts paid hereunder by the Corporation to the Depositary as fees and charges, but not including reimbursable expenses.

Notwithstanding anything in this Deposit Agreement to the contrary, neither the Depositary, nor the Depositary’s Agent nor any Registrar nor any Transfer Agent nor the Corporation shall be liable in any event for special, punitive, incidental, indirect or consequential losses or damages of any kind whatsoever (including but not limited to lost profits), even if they have been advised of the likelihood of such loss or damage and regardless of the form of action.

17

Neither the Depositary nor any Depositary’s Agent nor any Registrar nor any Transfer Agent nor the Corporation shall be under any obligation to appear in, prosecute or defend any action, suit or other proceeding in respect of the Series B Preferred Stock, the Depositary Shares or the Receipts which in its opinion may involve it in expense or liability unless indemnity reasonably satisfactory to it against all expense and liability be furnished as often as may be required.

Neither the Depositary nor any Depositary’s Agent nor any Registrar nor the Corporation shall be liable for any action or any failure to act by it in reliance upon (i) the written advice of legal counsel or accountants or (ii) information from any Person presenting Series B Preferred Stock for deposit, any Holder of a Receipt or any other Person believed by it in good faith to be competent to give such information. The Depositary, any Depositary’s Agent, any Registrar or Transfer Agent and the Corporation may each rely and shall each be protected in acting upon or omitting to act upon any written notice, request, direction or other document believed by it to be genuine and to have been signed or presented by the proper party or parties.

The Depositary shall not be responsible for any failure to carry out any instruction to vote any of the shares of Series B Preferred Stock or for the manner or effect of any such vote made, as long as any such action or non-action is not the result of the Depositary’s gross negligence, willful misconduct or bad faith (each as determined by a final non-appealable judgment of a court of competent jurisdiction). The Depositary undertakes, and any Registrar shall be required to undertake, to perform such duties and only such duties as are specifically set forth in this Deposit Agreement, and no implied covenants or obligations shall be read into this Deposit Agreement against the Depositary or any Registrar or any Transfer Agent.

The Depositary, the Depositary’s Agents, and any Registrar or Transfer Agent may own and deal in any class of securities of the Corporation and its affiliates and in Receipts. The Depositary may also act as transfer agent or registrar of any of the securities of the Corporation and its affiliates.

The Depositary shall not be under any liability for interest on any monies at any time received by it pursuant to any of the provisions of this Deposit Agreement or of the Receipts, the Depositary Shares or the Series B Preferred Stock nor shall it be obligated to segregate such monies from other monies held by it, except as required by law. The Depositary shall not be responsible for advancing funds on behalf of the Corporation and shall have no duty or obligation to make any payments if it has not timely received sufficient funds to make timely payments.

In the event the Depositary, the Depositary’s Agent, any Registrar or any Transfer Agent reasonably believes any ambiguity or uncertainty exists hereunder or in any notice, instruction, direction, request or other communication, paper or document received by it hereunder, or in the administration of any of the provisions of this Deposit Agreement, the Depositary, the Depositary’s Agent, any Registrar or any Transfer Agent shall reasonably deem it necessary that a matter be proved or established prior to taking, omitting or suffering to take any action hereunder, the Depositary, the Depositary’s Agent, any Registrar or any Transfer Agent may, in its sole discretion upon written notice to the Corporation, refrain from taking any action and shall be fully protected and shall not be liable in any way to the Corporation, any

18

Holders of Receipts or any other Person or entity for refraining from taking such action, unless the Depositary, the Depositary’s Agent, the Registrar or Transfer Agent, as applicable, receives written instructions or a certificate signed by a duly authorized officer of the Corporation which eliminates such ambiguity or uncertainty to the satisfaction of the Depositary, the Depositary’s Agent, any Registrar or any Transfer Agent or which proves or establishes the applicable matter to its satisfaction.

In the event the Depositary, any Depositary’s Agent, any Registrar or any Transfer Agent shall receive conflicting claims, requests or instructions from any Holder of a Receipt, on the one hand, and the Corporation, on the other hand, the Depositary, any Depositary’s Agent, any Registrar or any Transfer Agent, shall be entitled to act on such claims, requests or instructions received from the Corporation, and shall be entitled to the indemnification set forth in Section 5.7 hereof in connection with any action so taken.

From time to time, the Corporation may provide the Depositary, any Depositary’s Agent, any Registrar or any Transfer Agent with instructions concerning the services performed by the Depositary under this Deposit Agreement. In addition, at any time, the Depositary, any Depositary’s Agent, any Registrar or any Transfer Agent may apply to any officer of the Corporation for instruction, and may consult with legal counsel for the Depositary with respect to any matter arising in connection with the services to be performed by the Depositary, Depositary’s Agent, Registrar or Transfer Agent, as applicable, under this Deposit Agreement. The Depositary, Depositary’s Agent, Registrar, Transfer Agent and their respective agents and subcontractors shall not be liable and shall be indemnified by the Corporation for any action taken, suffered or omitted to be taken by them in reliance upon any written instructions from the Corporation or upon the advice or opinion of such counsel. None of the Depositary, any Depositary’s Agent, any Registrar or any Transfer Agent shall be held to have notice of any change of authority of any Person, until receipt of written notice thereof from the Corporation.

The Depositary, any Depositary’s Agent, Transfer Agent, and Registrar hereunder:

(i) may rely on and shall be authorized and protected in acting or omitting to act upon the written, telephonic, electronic and oral instructions given in accordance with this Deposit Agreement, with respect to any matter relating to its actions as Depositary, Transfer Agent or Registrar covered by this Deposit Agreement (or supplementing or qualifying any such actions), of officers of the Corporation;

(ii) shall not be called upon at any time to advise any Person with respect to the Series B Preferred Stock, Depositary Shares or Receipts;

(iii) shall not be liable or responsible for any recital or statement contained in any documents relating hereto or to the Series B Preferred Stock, the Depositary Shares or Receipts; and

(iv) shall not be liable in any respect on account of the identity, authority or rights of the parties (other than the Depositary) executing or delivering or purporting to execute or deliver this Deposit Agreement or any documents or papers deposited or called for under this Deposit Agreement.

19

The terms of this Section 5.4 shall survive the replacement, removal or resignation of any Depositary, Registrar, Transfer Agent or Depositary’s Agent or termination of this Deposit Agreement.

The Depositary may at any time resign as Depositary hereunder by delivering notice of its election to do so to the Corporation, such resignation to take effect upon the appointment of a successor Depositary and its acceptance of such appointment as hereinafter provided.

The Depositary may at any time be removed by the Corporation by notice of such removal delivered to the Depositary, such removal to take effect upon the appointment of a successor Depositary hereunder and its acceptance of such appointment as hereinafter provided.

In case at any time the Depositary acting hereunder shall resign or be removed, the Corporation shall, within 60 days after the delivery of the notice of resignation or removal, as the case may be, appoint a successor Depositary, which shall be a Person having its principal office in the United States of America and having a combined capital and surplus, along with its affiliates, of at least $50,000,000. If no successor Depositary shall have been so appointed and have accepted appointment within 60 days after delivery of such notice, the resigning or removed Depositary may petition any court of competent jurisdiction for the appointment of a successor Depositary. Every successor Depositary shall execute and deliver to its predecessor and to the Corporation an instrument in writing accepting its appointment hereunder, and thereupon such successor Depositary, without any further act or deed, shall become fully vested with all the rights, powers, duties and obligations of its predecessor and for all purposes shall be the Depositary under this Deposit Agreement, and such predecessor, upon payment of all sums due it and on the written request of the Corporation, shall promptly execute and deliver an instrument transferring to such successor all rights and powers of such predecessor hereunder, shall duly assign, transfer and deliver all right, title and interest in the Series B Preferred Stock and any moneys or property held hereunder to such successor, and shall deliver to such successor a list of the Record Holders of all outstanding Receipts and such records, books and other information in its possession relating thereto. Any successor Depositary shall promptly mail notice of its appointment (at the Corporation’s expense) to the Holders of Receipts.

Any entity into or with which the Depositary may be merged, consolidated or converted shall be the successor of the Depositary without the execution or filing of any document or any further act, and notice thereof shall not be required hereunder. Such successor Depositary may authenticate the Receipts in the name of the predecessor Depositary or its own name as successor Depositary.

The provisions of this Section 5.5 as they apply to the Depositary apply to the Registrar and Transfer Agent as if specifically enumerated herein.

20

The Corporation agrees that it will deliver to the Depositary, and the Depositary will, promptly after receipt thereof, transmit to the Record Holders of Receipts, in each case at the addresses recorded in the Depositary’s books, copies of all notices and reports (including without limitation financial statements) required by law, by the rules of any national securities exchange upon which the Series B Preferred Stock, the Depositary Shares or the Receipts are listed or by the Corporation’s Restated Articles of Incorporation (including the Certificate of Designations), to be furnished to the Record Holders of Receipts. Such transmission will be at the Corporation’s expense and the Corporation will provide the Depositary with such number of copies of such documents as the Depositary may reasonably request. In addition, the Depositary will transmit to the Record Holders of Receipts at the Corporation’s expense such other documents as may be requested by the Corporation.

The Corporation shall indemnify the Depositary, any Depositary’s Agent and any Registrar (including each of their officers, directors, agents and employees) against, and hold each of them harmless from, any loss, damage, cost, penalty, liability or expense (including the reasonable costs and expenses of defending itself) which may arise out of acts performed, suffered or omitted to be taken in connection with this Deposit Agreement and the Receipts by the Depositary, any Registrar, any Transfer Agent or any of their respective agents (including any Depositary’s Agent) and any transactions or documents contemplated hereby, except for any liability arising out of gross negligence, willful misconduct or bad faith (each as determined by a final non-appealable judgment of a court of competent jurisdiction) on the respective parts of any such Person or Persons. The obligations of the Corporation and the rights of the Depositary set forth in this Section 5.7 shall survive the termination of this Deposit Agreement and any resignation or replacement, removal, succession of any Depositary, Registrar, Transfer Agent or Depositary’s Agent.

The Corporation agrees promptly to pay the Depositary the compensation to be agreed upon with the Corporation for all services rendered by the Depositary hereunder and to reimburse the Depositary for its reasonable out-of-pocket expenses (including reasonable counsel fees and expenses) incurred by the Depositary without gross negligence, willful misconduct or bad faith on its part (or on the part of any agent or Depositary Agent) in connection with the services rendered by it (or such agent or Depositary Agent) hereunder. The Corporation shall pay all charges of the Depositary in connection with the initial deposit of the Series B Preferred Stock and the initial issuance of the Depositary Shares, all withdrawals of shares of Series B Preferred Stock by owners of Depositary Shares, and any redemption or exchange of the Series B Preferred Stock at the option of the Corporation. The Corporation shall pay all transfer and other taxes and governmental charges arising solely from the existence of the depositary arrangements. All other transfer and other taxes and governmental charges shall be at the expense of Holders of Depositary Shares evidenced by Receipts. If, at the request of a Holder of Receipts, the Depositary incurs charges or expenses for which the Corporation is not otherwise liable hereunder, such Holder will be liable for such charges and expenses; provided, however, that the

21

Depositary may, at its sole option, require a Holder of a Receipt to prepay the Depositary any charge or expense the Depositary has been asked to incur at the request of such Holder of Receipts. The Depositary shall present its statement for charges and expenses to the Corporation at such intervals as the Corporation and the Depositary may agree.

Article VI

AMENDMENT AND TERMINATION

The form of the Receipts and any provisions of this Deposit Agreement may at any time and from time to time be amended by agreement between the Corporation and the Depositary in any respect which they may deem necessary or desirable; provided, however, that no such amendment which shall materially and adversely alter the rights of the Holders of Receipts shall be effective against the Holders of Receipts unless such amendment shall have been approved by the Holders of Receipts representing in the aggregate at least 66 2/3% of the Depositary Shares then outstanding. Every Holder of an outstanding Receipt at the time any such amendment becomes effective shall be deemed, by continuing to hold such Receipt, to consent and agree to such amendment and to be bound by the Deposit Agreement as amended thereby. In no event shall any amendment impair the right, subject to the provisions of Section 2.5 and Section 2.6 and Article III, of any owner of Depositary Shares to surrender any Receipt evidencing such Depositary Shares to the Depositary with instructions to deliver to the Holder the Series B Preferred Stock and all money and other property, if any, represented thereby, except in order to comply with mandatory provisions of applicable law or the rules and regulations of any governmental body, agency or commission, or applicable securities exchange. As a condition precedent to the Depositary’s execution of any amendment, the Corporation shall deliver to the Depositary a certificate from a duly authorized officer of the Corporation that states that the proposed amendment is in compliance with the terms of this Section 6.1.

This Deposit Agreement may be terminated by the Corporation or the Depositary only if (i) all outstanding Depositary Shares issued hereunder have been redeemed pursuant to Section 2.8, (ii) there shall have been made a final distribution in respect of the Series B Preferred Stock in connection with any liquidation, dissolution or winding up of the Corporation and such distribution shall have been distributed to the Holders of Receipts representing Depositary Shares pursuant to Section 4.1 or Section 4.2, as applicable or (iii) upon the consent of Holders of Receipts representing in the aggregate not less than 66 2/3% of the Depositary Shares outstanding.

Upon the termination of this Deposit Agreement, the Corporation shall be discharged from all obligations under this Deposit Agreement except for its obligations to the Depositary, any Depositary’s Agent and any Registrar under Section 5.7 and Section 5.8.
