On the basis of the representations and warranties herein contained and subject to the terms and conditions herein set forth, the Company agrees to sell to each Underwriter, severally and not jointly, and each Underwriter, severally and not jointly, agrees to purchase from the Company, at the price per Depositary Share set forth in Schedule 3 (the “Purchase Price”), the number of Initial Securities set forth in Schedule 1 opposite the name of such Underwriter, plus any additional number of Initial Securities which such Underwriter may become obligated to purchase pursuant to the provisions of Section 10, bears to the total number of Initial Securities.

(ii) The Option Securities. On the basis of the representations and warranties contained in this Agreement, and subject to its terms and conditions, the Company agrees to sell to the Underwriters the Option Securities, and the Underwriters shall have the right to purchase, severally and not jointly, up to 1,200,000 Option Securities at the Purchase Price; provided, however, that the amount paid by the Underwriters for any Option Securities shall be reduced by an amount per Depositary Share equal to any dividends declared by the Company and payable on the Initial Securities but not payable on such Option Securities. You may exercise this right on behalf of the Underwriters in whole or from time to time in part by giving written notice not later than 30 days after the date of this Agreement. Any exercise notice shall specify the number of Option Securities to be purchased by the Underwriters and the date on which such shares are to be purchased. Each purchase date must be at least two business days after the written notice is given and may not be earlier than the closing date for the Initial Securities nor later than ten business days after the date of such notice. On each day, if any, that Option Securities are to be purchased (an “Option Closing Date”), each Underwriter agrees, severally and not jointly, to purchase the number of Option Securities that

bears the same proportion to the total number of Option Securities to be purchased on such Option Closing Date as the number of Initial Securities set forth in Schedule 1 hereto opposite the name of such Underwriter bears to the total number of Initial Securities.

(iii) The Closing Date. The Initial Securities and Option Securities to be purchased by each Underwriter hereunder, in such authorized denominations and registered in such names as the Representatives may request upon at least forty-eight hours’ prior notice to the Company, will be represented by one or more definitive global certificates in book-entry form, which shall be deposited by or on behalf of the Company with The Depository Trust Company (“DTC”) or its designated custodian, for the respective accounts of the Underwriters of the Securities to be purchased by them, against payment by or on behalf of such Underwriters of the purchase price therefor by wire transfer of immediately available funds to the account specified by the Company at least forty-eight hours in advance, by the Company causing DTC to credit the Depositary Shares with respect to the Preferred Shares to the securities account(s) at DTC designated by the Representatives on behalf of the Underwriters. The time and date of such delivery and payment, with respect to the Initial Securities, shall be 10:00 a.m., New York City time, on November 24, 2015 (unless postponed in accordance with Section 10), or such other time and date as the Underwriters and the Company shall mutually agree (the time and date of such closing are called the “Closing Date”).

(iv) Public Offering of the Securities. The Representatives hereby advise the Company that the Underwriters intend to offer for sale to the public, as described in the Time of Sale Prospectus and the Prospectus, their respective portions of the Securities as soon after the Applicable Time of Sale as the Representatives, in their sole judgment, have determined is advisable and practicable.

(v) Payment for the Securities. Payment for the Initial Securities shall be made at the Closing Date by wire transfer of immediately available funds to the order of the Company. It is understood that the Representatives have been authorized, for their own account and for the respective accounts of the several Underwriters, to accept delivery of and receipt for, and make payment of the purchase price for, the Securities that the Underwriters have agreed to purchase. The Representatives may (but shall not be obligated to) make payment for the Securities to be purchased by any Underwriter whose funds shall not have been received by the Representatives by the Closing Date for the account of such Underwriter, but any such payment shall not relieve such Underwriter from any of its obligations under this Agreement. Payment for any Option Securities shall be made to the Company by wire transfer of immediately available funds against delivery of such Option Securities for the respective accounts of the several Underwriters at 10:00 a.m., New York City time on the date specified in the corresponding notice described in Section 2(ii) hereof.

3. Conditions to the Underwriters’ Obligations. The several obligations of the Underwriters to purchase and pay for the Initial Securities on the Closing Date are subject to the following conditions:

4. Covenants of the Company. In further consideration of the agreements of the Underwriters herein contained, the Company covenants with the Underwriters as follows:

(i) Compliance with Securities Regulations and Commission Requests. The Company, subject to Section 3(i), will comply with the requirements of Rule 430B, and will promptly notify the Representatives, and confirm the notice in writing, of (i) the effectiveness during the Prospectus Delivery Period (as defined below) of any post-effective amendment to the Registration Statement or the filing of any supplement or amendment to the Preliminary Prospectus or the Prospectus, (ii) the receipt of any comments from the Commission during the Prospectus Delivery Period, (iii) any request by the Commission for any amendment to the Registration Statement or any amendment or supplement to the Preliminary Prospectus or the Prospectus or for additional information, and (iv) the issuance by the Commission of any stop order suspending the effectiveness of the Registration Statement or of any order preventing or suspending the use of the Preliminary Prospectus or the Prospectus, or of the suspension of the qualification of the Securities for offering or sale in any jurisdiction, or of the initiation or threatening of any proceedings for any of such purposes. The Company will promptly effect the filings necessary pursuant to Rule 424 and will take such steps as it deems necessary to ascertain promptly whether the Preliminary Prospectus and the Prospectus transmitted for filing under Rule 424 was received for filing by the Commission and, in the event that it was not, it will promptly file such document. The Company will use its reasonable best efforts to prevent the issuance of any stop order and, if any stop order is issued, to obtain the lifting thereof at the earliest possible moment.

(ii) Filing of Amendments. During such period beginning on the date of this Agreement and ending on the later of the Closing Date or such date as, in the opinion of counsel for the Underwriters, the Prospectus is no longer required by law to be delivered in connection with sales of the Securities by an Underwriter or dealer, including in circumstances where such requirement may be satisfied pursuant to Rule 172 of the Rules and Regulations (the “Prospectus Delivery Period”), the Company will give the Representatives notice of its intention to file or prepare any amendment to the Registration Statement (including any filing under Rule 462(b) of the Rules and Regulations), or any amendment, supplement or revision to the Time of Sale Prospectus or the Prospectus, whether pursuant to the Securities Act, the Exchange Act or otherwise, will furnish the Representatives with copies of any such documents a reasonable amount of time prior to such proposed filing or use, as the case may be, and will not file or use any such document to which the Representatives or counsel for the Underwriters shall reasonably object.

(iii) Delivery of Registration Statements. The Company has furnished or will deliver to the Representatives and counsel for the Underwriters, without charge, signed copies of the Registration Statement as originally filed and of each amendment thereto (including exhibits filed therewith or incorporated by reference therein and documents incorporated or deemed to be incorporated by reference therein) and signed copies of all consents and certificates of experts, and will also deliver to the Representatives, without charge, a conformed copy of the Registration Statement as originally filed and of each amendment thereto (without exhibits) for each of the Underwriters. The Registration Statement and each amendment thereto furnished to the Underwriters will be identical to any electronically transmitted copies thereof filed with the Commission pursuant to ▇▇▇▇▇, except to the extent permitted by Regulation S-T.

(iv) Delivery of Prospectuses. The Company will deliver to each Underwriter, without charge, as many copies of the Preliminary Prospectus as such Underwriter may reasonably request, and the Company hereby consents to the use of such copies for purposes permitted by the Securities Act. The Company will furnish to each Underwriter, without charge, during the Prospectus Delivery Period, such number of copies of the Prospectus as such Underwriter may reasonably request. The Preliminary Prospectus and the Prospectus and any amendments or supplements thereto furnished to the Underwriters will be identical to any electronically transmitted copies thereof filed with the Commission pursuant to ▇▇▇▇▇, except to the extent permitted by Regulation S-T.

(v) Continued Compliance with Securities Laws. The Company will comply with the Securities Act and the Exchange Act so as to permit the completion of the distribution of the Securities as contemplated in this Agreement and in the Registration Statement, the Time of Sale Prospectus and the Prospectus. If at any time during the Prospectus Delivery Period, any event shall occur or condition shall exist as a result of which it is necessary, in the opinion of counsel for the Underwriters or for the Company, to amend the Registration Statement in order that the Registration Statement will not contain an untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein not misleading or to amend or supplement the Time of Sale Prospectus or the Prospectus in order that the Time of Sale Prospectus or the Prospectus, as the case may be, will not include an untrue statement of a material fact or omit to state a material fact necessary in order to make the statements therein, in the light of the circumstances existing at the Initial Sale Time or at the time it is delivered or conveyed to a purchaser, not misleading, or if it shall be necessary, in the opinion of either such counsel, at any such time to amend the Registration Statement or amend or supplement the Time of Sale Prospectus or the Prospectus in order to comply with the requirements of any law, the Company will notify the Representatives of any such event, development or condition and promptly prepare and file with the Commission, subject to Section 3(i), such amendment or supplement as may be necessary to correct such statement or omission or to make the Registration Statement, the Time of Sale Prospectus or the Prospectus comply with such law, and the Company will furnish to the Underwriters, without charge, such number of copies of such amendment or supplement as the Underwriters may reasonably request.

(vi) Blue Sky Compliance. The Company shall cooperate with the Representatives and counsel for the Underwriters to qualify or register the Securities for sale under (or obtain exemptions from the application of) the state securities or blue sky laws of those jurisdictions designated by the Representatives, shall comply with such laws and shall continue such qualifications, registrations and exemptions in effect so long as required for the distribution of the Securities. The Company shall not be required to qualify to transact business or to take any action that would subject it to general service of process in any such jurisdiction where it is not presently qualified or where it would be subject to taxation as a foreign business. The Company will advise the Representatives promptly of the suspension of the qualification or registration of (or any such exemption relating to) the Securities for offering, sale or trading in any jurisdiction or any initiation or threat of any proceeding for any such purpose, and in the event of the issuance of any order suspending such qualification, registration or exemption, the Company shall use its best efforts to obtain the withdrawal thereof at the earliest possible moment.

(vii) Listing. The Company will use its reasonable best efforts to effect and maintain the listing of the Depositary Shares on the New York Stock Exchange (the “NYSE”).

During a period of 30 days from the date of the Prospectus, the Company will not, without the prior written consent of the Representatives, (i) offer, pledge, sell, contract to sell, sell any option or contract to purchase, purchase any option or contract to sell, grant any option, right or warrant to purchase, lend or otherwise transfer or dispose of, directly or indirectly, any preferred shares, including, without limitation, the Preferred Shares or the Depositary Shares or any securities convertible into or exercisable or exchangeable for preferred shares or depositary shares representing interests therein, including the Preferred Shares or the Depositary Shares, or file any registration statement under the Securities Act with respect to any of the foregoing or (ii) enter into any swap or any other agreement or any transaction that transfers, in whole or in part, directly or indirectly, the economic consequence of ownership of any such securities, whether any such swap or transaction described in clause (i) or (ii) above is to be settled by delivery of such securities, in cash or otherwise. The foregoing sentence shall not apply to the Securities to be sold hereunder.

(xii) Final Term Sheet. The Company will prepare a final term sheet containing only a description of the Securities, substantially in the form approved by the Underwriters and included in Schedule 2, and will file such term sheet pursuant to Rule 433(d) within the time required by such rule (such term sheet, the “Final Term Sheet”). Any such Final Term Sheet is an Issuer Free Writing Prospectus for purposes of this Agreement.

(xiii) Permitted Free Writing Prospectuses. The Company represents that it has not made, and agrees that, unless it obtains the prior written consent of the Representatives, it will not make, any offer relating to the Securities that would constitute an Issuer Free Writing Prospectus or that would otherwise constitute a “free writing prospectus” (as defined in Rule 405) required to be filed by the Company with the Commission or retained by the Company under Rule 433; provided that the prior written consent of the Representatives shall be deemed to have been given in respect of any Issuer Free Writing Prospectuses included in Schedule 4 to this Agreement. Any such free writing prospectus consented to or deemed to be consented to by the Representatives is hereinafter referred to as a “Permitted Free Writing Prospectus.” The Company agrees that (i) it has treated and will treat, as the case may be, each Permitted Free Writing Prospectus as an Issuer Free Writing Prospectus, and (ii) has complied and will comply, as the case may be, with the requirements of Rules 164 and 433 applicable to any Permitted Free Writing Prospectus, including in respect of timely filing with the Commission, legending and record keeping. The Company consents to the use by any Underwriter of a free writing prospectus that (a) is not an “issuer free writing prospectus” as defined in Rule 433, and (b) contains only (i) information describing the preliminary terms of the Securities or their offering, (ii) information permitted by Rule 134 of the Rules and Regulations or (iii) information that describes the final terms of the Securities or their offering and that is included in the Final Term Sheet of the Company contemplated in Section 4(xii).

(xiv) Registration Statement Renewal Deadline. If immediately prior to the third anniversary (the “Renewal Deadline”) of the initial effective date of the Registration Statement, any of the Securities remain unsold by the Underwriters, the Company will prior to the Renewal Deadline file, if it has not already done so and is eligible to do so, a new automatic shelf registration statement relating to the Securities, in a form reasonably satisfactory to the Representatives. If the Company is no longer eligible to file an automatic shelf registration statement, the Company will prior to the Renewal Deadline, if it has not already done so, file a new shelf registration statement relating to the Securities, in a form satisfactory to the Representatives, and will use its best efforts to cause such registration statement to be declared effective within 60 days after the Renewal Deadline. The Company will take all other action necessary or appropriate to permit the public offering and sale of the Securities to continue as contemplated in the expired registration statement relating to the Securities. References herein to the Registration Statement shall include such new automatic shelf registration statement or such new shelf registration statement, as the case may be.

(xv) Notice of Inability to Use Automatic Shelf Registration Statement Form. If at any time during the Prospectus Delivery Period, the Company receives from the Commission a notice pursuant to Rule 401(g)(2) or otherwise ceases to be eligible to use the automatic shelf registration statement form, the Company will (i) promptly notify the

Representatives, (ii) promptly file a new registration statement or post-effective amendment on the proper form relating to the Securities, in a form satisfactory to the Representatives, (iii) use its best efforts to cause such registration statement of post-effective amendment to be declared effective and (iv) promptly notify the Representatives of such effectiveness. The Company will take all other action necessary or appropriate to permit the public offering and sale of the Securities to continue as contemplated in the registration statement that was the subject of the Rule 401(g)(2) notice or for which the Company has otherwise become ineligible. References herein to the Registration Statement shall include such new registration statement or post-effective amendment, as the case may be.

(xvi) Filing Fees. The Company agrees to pay the required Commission filing fees relating to the Securities within the time required by and in accordance with Rules 456(b)(1) and 457(r) of the Rules and Regulations.

(xvii) No Manipulation of Price. The Company will not take, directly or indirectly, any action designed to cause or result in, or that has constituted or might reasonably be expected to constitute, under the Exchange Act or otherwise, the stabilization or manipulation of the price of any securities of the Company to facilitate the sale or resale of the Securities.

5. Covenants of the Underwriters. Each of the Underwriters hereby represent and agree that:

(i) It has not made, and will not make any offer relating to the Securities that would constitute a free writing prospectus, without the prior consent of the Company, which consent shall not be unreasonably withheld.

(ii) Any free writing prospectus used or referred to by it will not be subject to broad unrestricted dissemination and will not be required to be filed with the Commission, in accordance with Rule 433 under the Securities Act, as a result of any action taken or caused to be taken by the Underwriter, which is not consented to in advance by the Company.

financial markets in the United States or in the international financial markets, any outbreak of hostilities or escalation thereof or other calamity or crisis that, in the judgment of the Underwriters, make it impracticable or inadvisable to market the Securities or to enforce contracts for the sale of the Securities, or (c) if trading in any securities of the Company has been suspended or materially limited by the Commission or the NYSE, or if trading generally on the NYSE or in the Nasdaq Global Market has been suspended or materially limited, or minimum or maximum prices for trading have been fixed, or maximum ranges for prices have been required, by any of said exchanges or by such system or by order of the Commission, the FINRA or any other governmental authority, or a material disruption has occurred in commercial banking or securities settlement or clearance services in the United States, or (d) if a banking moratorium has been declared by either federal or New York authorities.

An Indemnifying Party may participate at its own expense in the defense of any such action; provided that counsel to the Indemnifying Party shall not (except with the consent of the Indemnified Party) also be counsel to the Indemnified Party. In case any such action shall be brought against any Indemnified Party and it shall notify the Indemnifying Party of the commencement thereof, the Indemnifying Party shall be entitled to participate therein and, to the extent that it shall wish, jointly with any other Indemnifying Party similarly notified, to assume the defense thereof, with counsel satisfactory to such Indemnified Party (who shall not, except with the consent of the indemnified party, be counsel to the indemnifying party), and, after notice from the Indemnifying Party to such Indemnified Party of its election so to assume the defense thereof, the Indemnifying Party shall not be liable to such Indemnified Party under such subsection for any legal expenses of other counsel or any other expenses, in each case subsequently incurred by such Indemnified Party, in connection with the defense thereof other than reasonable costs of investigation, provided, however, that if the defendants in any such action include both the Indemnified Party and the Indemnifying Party and the Indemnified Party shall have reasonably concluded that there may be legal defenses available to it and/or other Indemnified Parties which are different from or additional to those available to the Indemnifying Party, the Indemnified Party or Parties shall have the right to select separate counsel to assert such legal defenses and to otherwise participate in the defense of such action on behalf of such Indemnified Party or Parties and the Indemnifying Party shall remain liable for the legal expenses of such separate counsel. No Indemnifying Party shall, without the written consent of the Indemnified Party, effect the settlement or compromise of, or consent to the entry of any judgment with respect to, any pending or threatened action or claim in respect of which indemnification or contribution may be sought hereunder (whether or not the Indemnified Party is an actual or potential party to such action or claim) unless such settlement, compromise or judgment (i) includes an unconditional release of the Indemnified Party from all liability arising out of such action or claim and (ii) does not include a statement as to or an admission of fault, culpability or a failure to act, by or on behalf of any Indemnified Party.

(v) Control Persons. The obligations of the Company under this Section 8 shall be in addition to any liability which the Company may otherwise have and shall extend, upon the same terms and conditions, to each person, if any, who controls an Underwriter or within the meaning of the Securities Act and the obligations of the Underwriters under this Section 8 shall extend, upon the same terms and conditions, to each officer and director of the Company and to each person, if any, who controls the Company within the meaning of the Act.

9. Contribution. If the indemnification provided for in Section 8(ii) or (iii) is unavailable to or insufficient to hold harmless an Indemnified Party in respect of any reason, the Company and the Underwriters agree to contribute to the aggregate losses, claims, damages or liabilities (or actions in respect thereof) referred to in Section 8, then each Indemnifying Party shall contribute to the amount paid or payable by such Indemnified Party in such proportion as is appropriate to reflect the relative benefits received by the Underwriters on the one hand and by the Company on the other from the offering of the Securities. If, however, the allocation provided by the immediately preceding sentence is not permitted by applicable law or if the Indemnified Party failed to give the notice required under Section 8 above, then each Indemnifying Party shall contribute to such amount paid or payable by such Indemnified Party in such proportion as is appropriate to reflect not only such relative benefits but also the relative fault of the Underwriters on the one hand and of the Company on the other in connection with the statements or omissions which resulted in such losses, claims, damages or liabilities (or actions in respect thereof), as well as any other relevant equitable considerations. The relative benefits received by the Company on the one hand and the Underwriters on the other hand in connection with the offering of the Securities shall be deemed to be in the same respective proportions as the net proceeds from the offering of the Securities (before deducting expenses) received by the Company, on the one hand, and the total underwriting discounts and commissions received by the Underwriters, on the other hand, in each case as set forth in the table on the cover of the Prospectus, bear to the aggregate public offering price of the Securities. The relative fault shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information supplied by the Underwriters on the one hand and of the Company on the other and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission.

The Company and the Underwriters agree that it would not be just and equitable if contributions pursuant to this Section 9 were determined by pro rata allocation or by any other method of allocation which does not take account of the equitable considerations referred to above in this Section 9. The amount paid or payable by an Indemnified Party as a result of the losses, claims, damages or liabilities (or actions in respect thereof) referred to above in this Section 9 shall be deemed to include any legal or other expenses reasonably incurred by such Indemnified Party in connection with investigating or defending any such action or claim. Notwithstanding the provisions of this Section 9, the Underwriters shall not be required to contribute any amount in excess of the amount by which the total price at which the Securities underwritten by it and distributed to the public were offered to the public exceeds the amount of any damages which the Underwriters have otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation.

10. Default of One or More of the Several Underwriters. If, on the Closing Date or an Option Closing Date, as the case may be, any one or more of the Underwriters shall fail or refuse to purchase Securities that it has or they have agreed to purchase hereunder on such date, and the aggregate number of Securities which such defaulting Underwriter or Underwriters agreed but failed or refused to purchase is not more than one-tenth of the aggregate number of the Securities to be purchased on such date, the other Underwriters shall be obligated severally in the proportions that the number of such Securities set forth opposite their respective names in Schedule 1 bears to the aggregate number of such Securities set forth opposite the names of all such non-defaulting Underwriters, or in such other proportions as you may specify, to purchase the Securities which such defaulting Underwriter or Underwriters agreed but failed or refused to purchase on such date. If, on the Closing Date, any Underwriter or Underwriters shall fail or refuse to purchase Initial Securities and the aggregate number of Initial Securities with respect to which such default occurs is more than one-tenth of the aggregate number of Initial Securities to be purchased on such date, and arrangements satisfactory to you and the Company for the purchase of such Initial Securities are not made within 36 hours after such default, this Agreement shall terminate without liability on the part of any non-defaulting Underwriter or the Company except that the provisions of Sections 4, 6, 8, 9 and 14 shall at all times be effective and shall survive such termination. In any such case you or the Company shall have the right to postpone the Closing Date, but in no event for longer than seven days, in order that the required changes, if any, in the Registration Statement, in the Time of Sale Prospectus, in the Prospectus or in any other documents or arrangements may be effected. If, on an Option Closing Date, any Underwriter or Underwriters shall fail or refuse to purchase Option Securities and the aggregate number of Option Securities with respect to which such default occurs is more than one-tenth of the aggregate number of Option Securities to be purchased on such Option Closing Date, the non-defaulting Underwriters shall have the option to (i) terminate their obligation hereunder to purchase the Option Securities to be sold on such Option Closing Date or (ii) purchase not less than the number of Option Securities that such non-defaulting Underwriters would have been obligated to purchase in the absence of such default. Any action taken under this paragraph shall not relieve any defaulting Underwriter from liability in respect of any default of such Underwriter under this Agreement.

As used in this Agreement, the term “Underwriters” shall be deemed to include any person substituted for a defaulting Underwriter under this Section 10. Any action taken under this Section 10 shall not relieve any defaulting Underwriter from liability in respect of any default of such Underwriter under this Agreement.
