The Firm Shares and the Optional Shares are referred to herein, collectively, as the “ Shares ”. The shares of Preferred Stock represented by the Shares (the “ Preferred Shares ”), when issued, will be deposited against delivery of depositary receipts (the “ Depositary Receipts ”), which will evidence the Shares and will be issued by Equiniti Trust Company (the “ Depositary ”) under a deposit agreement, to be dated March 29, 2018 (the “ Deposit Agreement ”), among the Company, the Depositary and the holders from time to time of the Depositary Receipts issued hereunder. The terms of the Preferred Stock will be set forth in a certificate of designations (the “ Certificate of Designations ”) to be filed by the Company with the Secretary of State of the State of Delaware.

1

proceedings for such purpose are pending before or, to the knowledge of the Company, threatened by the Commission.  If the Registration Statement is an automatic shelf registration statement as defined in Rule 405 under the Act, the Company is eligible to use the Registration Statement as an automatic shelf registration statement and the Company has not received notice that the Commission objects to the use of the Registration Statement as an automatic shelf registration statement.  The Company proposes to file with the Commission pursuant to Rule 424 under the Act a supplement or supplements relating to the Shares and the Preferred Shares and the plan of distribution thereof to the form of prospectus included in the Registration Statement; such prospectus in the form in which it appears in the Registration Statement is hereinafter called the “ Basic Prospectus ”; and such Basic Prospectus, as so supplemented by the prospectus supplement or supplements relating to the Shares and the Preferred Shares in the form provided to the Underwriters by the Company and first used to confirm sales of the Shares (or in the form first made available to the Underwriters by the Company to meet requests of purchasers pursuant to Rule 173 under the Act), is hereinafter called the “ Final Prospectus .” Any preliminary form or forms of the Final Prospectus which has heretofore been filed pursuant to Rule 424 is hereinafter called the “ Preliminary Final Prospectus .” For purposes of this Agreement, “ free writing prospectus ” means a free writing prospectus as such term is defined in Rule 405 under the Act relating to the Shares and the Preferred Shares.  “ Time of Sale Prospectus ” means the Preliminary Final Prospectus, as amended or supplemented, and the final term sheet or sheets relating to the Shares and the Preferred Shares set forth in Schedule II (the “ Final Term Sheet ”), considered together, as of 3:55 p.m., Eastern Time, on March 26, 2018 (the “ Applicable Time ”).  Any reference herein to the Registration Statement, the Basic Prospectus, any Preliminary Final Prospectus, the Time of Sale Prospectus or the Final Prospectus shall be deemed to refer to and include the documents incorporated by reference therein pursuant to Item 12 of Form S-3 which were filed under the Securities Exchange Act of 1934, as amended (the “ Exchange Act ”), on or before the date of this Agreement, or the issue date of the Basic Prospectus, any Preliminary Final Prospectus, the Time of Sale Prospectus or the Final Prospectus, as the case may be; and any reference herein to the terms “amend,” “amendment” or “supplement” with respect to the Registration Statement, the Basic Prospectus, any Preliminary Final Prospectus, the Time of Sale Prospectus, the Final Prospectus, or any free writing prospectus shall be deemed to refer to and include the filing of any free writing prospectus and the filing of any document under the Exchange Act after the date of this Agreement, or the issue date of the Basic Prospectus, any Preliminary Final Prospectus, the Time of Sale Prospectus, the Final Prospectus, or any free writing prospectus, as the case may be, deemed to be incorporated therein by reference.

8.                                       Reimbursement of Underwriters’ Expenses .  If the sale of the Shares provided herein is not consummated because any condition to the obligations of the Underwriters set forth in Section 7 (other than Section 7(d)) hereof is not satisfied, because of any termination pursuant to Section 12(i) hereof or because of any refusal, inability or failure by the Company to perform any agreement herein or comply with any provision hereof other than by reason of a default by any of the Underwriters, the Company will reimburse the Underwriters severally through Morgan Stanley on demand for all reasonable out-of-pocket expenses (including reasonable fees and disbursements of counsel) that shall have been incurred by them in connection with the proposed purchase and sale of the Shares.

9.                                       Covenants of the Underwriters; Offering Restrictions .

(a)                                  Each Underwriter represents and agrees that, without the prior consent of the Company and the Representatives, other than (x) the Final Term Sheet and (y) one or more term sheets relating to the Shares containing customary information and conveyed to purchasers of Shares and that would not constitute an Issuer Free Writing Prospectus, it has not made and will not make any offer relating to the Shares that would constitute a free writing prospectus.  The Underwriters acknowledge and agree that, except for information consistent in all material respects with the Final Term Sheet and except as may be set forth in Schedule II or III, the Company has not authorized or approved any “issuer information” (as defined in Rule 433(h) under the Act) for use in any free writing prospectus prepared by or on behalf of the Underwriters.

(b)                                  Each Underwriter acknowledges, represents and agrees that it has not offered, sold or delivered and it will not offer, sell or deliver, any of the Shares, in or from any jurisdiction, including those jurisdictions set forth on Schedule VIII, except under circumstances that are reasonably designed to result in compliance with the applicable securities laws and regulations thereof.

10.                                Indemnification and Contribution .

(a)                                  The Company agrees to indemnify and hold harmless each Underwriter, the directors, officers, employees and agents of each Underwriter and each person who controls any Underwriter, within the meaning of either the Act or the Exchange Act, against any and all losses, claims, damages or liabilities, joint or several, to which they or any of them may become subject under the Act, the Exchange Act or other Federal or state statutory law or regulation, at common law or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) (i) arise out of or are based upon any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement as originally filed or in any amendment thereof or arise out of or are based upon the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading or (ii) arise out of or are based upon any untrue statement or alleged untrue statement of a

15

material fact contained in the Basic Prospectus, any Preliminary Final Prospectus, the Time of Sale Prospectus, the Final Prospectus or any Issuer Free Writing Prospectus, including those set forth on Schedule II or III hereof or arise out of or are based upon the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading.  The Company agrees to reimburse each such indemnified party, as incurred, for any legal or other expenses reasonably incurred by them in connection with investigating or defending any such loss, claim, damage, liability or action; provided, however, that the Company will not be liable in any such case arising in connection with this Section 10 to the extent that any such loss, claim, damage or liability (or action in respect thereof) arises out of or is based upon any such untrue statement or alleged untrue statement or omission or alleged omission made therein in reliance upon and in conformity with written information furnished to the Company by or on behalf of any Underwriter specifically for inclusion therein.  This indemnity agreement will be in addition to any liability which the Company may otherwise have.

(b)           Each Underwriter, severally and not jointly, agrees to indemnify and hold harmless the Company, each of its directors, each of its officers who signs the Registration Statement, and each person who controls the Company within the meaning of either the Act or the Exchange Act, to the same extent as the foregoing indemnity from the Company to each Underwriter, but only with reference to written information furnished to the Company by or on behalf of such Underwriter specifically for inclusion in the documents referred to in the foregoing indemnity.  This indemnity agreement will be in addition to any liability which any Underwriter may otherwise have.

(c)           Promptly after receipt by an indemnified party under this Section 10 of notice of the commencement of any action, such indemnified party will, if a claim in respect thereof is to be made against the indemnifying party under this Section 10, notify the indemnifying party in writing of the commencement thereof; but the failure so to notify the indemnifying party: (i) will not relieve the indemnifying party from liability under paragraph (a) or (b) above unless and to the extent it did not otherwise learn of such action and such failure results in the forfeiture by the indemnifying party of substantial rights and defenses; and (ii) will not, in any event, relieve the indemnifying party from any obligations to any indemnified party other than the indemnification obligation provided in paragraph (a) or (b) above.  The indemnifying party shall be entitled to appoint counsel of the indemnifying party’s choice at the indemnifying party’s expense to represent the indemnified party in any action for which indemnification is sought (in which case the indemnifying party shall not thereafter be responsible for the fees and expenses of any separate counsel retained by the indemnified party or parties except as set forth below) and to participate in and assume the defense of the claim associated with such action; provided, however, that such counsel shall be satisfactory to the indemnified party.  Notwithstanding the indemnifying party’s election to appoint counsel to represent the indemnified party in an action, the indemnified party shall have the right to employ separate counsel (including local counsel), and the indemnifying party shall bear the reasonable fees, costs and expenses of such separate counsel if: (A) the use of counsel chosen by the indemnifying party to represent the indemnified party would present such counsel with a conflict of interest; (B) the actual or potential

16

defendants in, or targets of, 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; (C) the indemnifying party shall not have employed counsel satisfactory to the indemnified party to represent the indemnified party within a reasonable time after notice of the institution of such action; or (D) the indemnifying party shall authorize the indemnified party to employ separate counsel at the expense of the indemnifying party.  An indemnifying party will not, without the prior written consent of the indemnified parties, settle or compromise, or consent to the entry of any judgment with respect to any pending or threatened claim, action, suit or proceeding in respect of which indemnification or contribution may be sought hereunder (whether or not the indemnified parties are actual or potential parties to such claim or action), unless such settlement, compromise or consent (x) includes an unconditional release of each indemnified party from all liability arising out of such claim, action, suit or proceeding and (y) 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.

(d)           In the event that the indemnity provided in paragraph (a) or (b) of this Section 10 is unavailable to, or insufficient to hold harmless, an indemnified party for any reason, the Company and the Underwriters severally agree to contribute to the aggregate losses, claims, damages and liabilities (including legal or other expenses reasonably incurred in connection with investigating or defending same) (collectively “Losses”) to which the Company and one or more of the Underwriters may be subject in such proportion as is appropriate to reflect the relative benefits received by the Company, on the one hand, and by the Underwriters, on the other, from the offering of the Shares; provided, however, that in no case shall any Underwriter (except as may be provided in any agreement among underwriters relating to the offering of the Shares) be responsible for any amount in excess of the total price at which the applicable Shares underwritten by it and distributed to the public were offered to the public.  If the allocation provided by the immediately preceding sentence is unavailable for any reason, the Company and the Underwriters severally shall contribute in such proportion as is appropriate to reflect not only such relative benefits but also the relative fault of the Company, on the one hand, and of the Underwriters, on the other, in connection with the statements or omissions which resulted in such Losses as well as any other relevant equitable considerations.  Benefits received by the Company shall be deemed to be equal to the total net proceeds from the offering (before deducting expenses) received by it, and benefits received by the Underwriters shall be deemed to be equal to the total underwriting discounts and commissions, in each case as set forth on the cover page of the Final Prospectus.  Relative fault shall be determined by reference to, among other things: (i) whether any untrue or any alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information provided by the Company, on the one hand, or the Underwriters, on the other; (ii) the intent of the parties and their relative knowledge; (iii) access to information; and (iv) the opportunity to correct or prevent such untrue statement or omission.  The Company and the Underwriters agree that it would not be just and equitable if contribution were determined by pro rata allocation or any other method of allocation which does not take account of the equitable considerations referred

17

to above.  Notwithstanding the provisions of this paragraph (d), no person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation.  For purposes of this Section 10, each person who controls an Underwriter within the meaning of either the Act or the Exchange Act and each director, officer, employee and agent of an Underwriter shall have the same rights to contribution as such Underwriter, and each person who controls the Company within the meaning of either the Act or the Exchange Act, each officer of the Company who shall have signed the Registration Statement and each director of the Company shall have the same rights to contribution as the Company, subject in each case to the applicable terms and conditions of this paragraph (d).

11.          Defaulting Underwriters .  If any one or more Underwriters shall fail at a Time of Delivery to purchase and pay for any of the Shares agreed to be purchased by the Underwriter or Underwriters hereunder and such failure to purchase shall constitute a default in the performance of its obligations under this Agreement, the remaining Underwriters shall be obligated severally to take up and pay for (in the respective proportions which the amount of Shares set forth opposite their names on Schedule I hereto bears to the aggregate amount of Shares set forth opposite the names of all the remaining Underwriters) the Shares which the defaulting Underwriter or Underwriters agreed but failed to purchase; provided , however , that in the event that the aggregate amount of Shares which the defaulting Underwriter or Underwriters agreed but failed to purchase shall exceed 10% of the aggregate amount of Shares to be purchased at such Time of Delivery, the remaining Underwriters shall have the right to purchase all, but shall not be under any obligation to purchase any, of the Shares and if such non-defaulting Underwriters do not purchase all the Shares, this Agreement (or, with respect to any Second Time of Delivery, the obligations of the Underwriters to purchase and of the Company to sell the Optional Shares at such Time of Delivery) will terminate without any liability to any non-defaulting Underwriter or the Company.  In the event of a default by any Underwriter as set forth in this Section 11, the related Time of Delivery shall be postponed for such period, not exceeding five Business Days, as the Representatives shall determine in order that the required changes to the Registration Statement, the Time of Sale Prospectus, and the Final Prospectus (including by means of a free writing prospectus) or in any other documents or arrangements may be effected.  Nothing contained in this Agreement shall relieve any defaulting Underwriter of its liability, if any, to the Company and any non-defaulting Underwriter for damages occasioned by its default hereunder.

12.          Termination .  This Agreement is subject to termination in the absolute discretion of the Representatives, by notice given to the Company prior to delivery of and payment for the Shares, if at any time prior to such time (i) trading in the Company’s securities shall have been suspended by the Commission, (ii) trading in securities generally on the NYSE shall have been suspended or limited or minimum prices shall have been established on such Exchange, (iii) a banking moratorium shall have been declared either by Federal or New York State authorities or (iv) there shall have occurred any outbreak or escalation of hostilities, declaration by the United States of a national emergency or war, or other calamity or crisis the effect of which on financial markets is such as to make it, in the sole judgment of the Representatives, impractical or inadvisable to proceed with the offering or delivery of the Shares as contemplated by the Time of Sale Prospectus or the Final Prospectus (exclusive of any supplements thereto).

18

13.          Representations and Indemnities to Survive .  The respective agreements, representations, warranties, indemnities and other statements of the Company or its officers and of the several Underwriters set forth in or made pursuant to this Agreement will remain in full force and effect, regardless of any investigation made by or on behalf of any Underwriter or the Company or any of the officers, directors, employees, agents or controlling persons referred to in Section 10 hereof, and will survive the delivery of and payment for the Shares.  The provisions of Sections 8 and 10 hereof shall survive the termination or cancellation of this Agreement.

14.          Notices .  All communications hereunder will be in writing and effective only on receipt, and, if sent to the Representatives, will be mailed, delivered or telefaxed to Morgan Stanley & Co. LLC, 1585 Broadway, 29th Floor, New York, New York 10036, facsimile number (212) 507-8999, Attention: Investment Banking Division, with a copy to the Legal Department; Merrill Lynch, Pierce, Fenner & Smith Incorporated, 50 Rockefeller Plaza, NY1-050-12-01, New York, New York 10020, facsimile number (212) 901-7881, Attention: High Grade Debt Capital Markets Transaction Management/Legal; UBS Securities LLC, 1285 Avenue of the Americas, New York, New York 10019, facsimile number (203) 719-0495, Attention: Fixed Income Syndicate; and Wells Fargo Securities, LLC, 550 South Tryon Street, 5th Floor, Charlotte, North Carolina 28202, facsimile number (704) 410-0326, Attention: Transaction Management; with a copy to Mayer Brown LLP, 71 South Wacker Drive, Chicago, Illinois 60606, Attn: Edward S.

15.          Successors and Assigns .  This Agreement will inure to the benefit of and be binding upon the parties hereto and their respective successors and the officers, directors, employees, agent and controlling persons referred to in Section 10 hereof, and no other person will have any right or obligation hereunder.  No purchaser of any of the Shares from any Underwriter shall be deemed a successor or assignee by reason merely of such purchase.

16.          Time; “Business Day” .  As used herein, the term “Business Day” shall mean any day other than a Saturday, Sunday or a legal holiday or a day on which banking institutions or trust companies are authorized or obligated by law to close in New York City.

17.          Fiduciary Duties .  The Company acknowledges that in connection with the offering of the Shares: (a) the Underwriters have acted at arms length, are not agents of, and owe no fiduciary duties to, the Company or any other person, (b) the Underwriters owe the Company only those duties and obligations set forth in this Agreement and prior written agreements (to the extent not superseded by this Agreement), if any, and (c) the Underwriters may have interests that differ from those of the Company.  The Company waives to the full extent permitted by applicable law any claims it may have against the Underwriters arising from an alleged breach of fiduciary duty in connection with the offering of the Shares.

18.          Patriot Act . In accordance with the requirements of the USA Patriot Act (Title III of Pub. L. 107-56 (signed into law October 26, 2001)), the Underwriters are required to obtain, verify and record information that identifies their respective clients, including the Company,

19

which information may include the name and address of their respective clients, as well as other information that will allow the Underwriters to properly identify their respective clients.

19.          GOVERNING LAW .  THIS AGREEMENT SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE INTERNAL LAWS OF THE STATE OF NEW YORK.

20.          Waiver of Jury Trial .  Each of the Company (on its behalf and, to the extent permitted by applicable law, on behalf of its stockholders and affiliates) and the Underwriters hereby irrevocably waives, to the fullest extent permitted by applicable law, any and all right to trial by jury in any legal proceeding arising out of or relating to this Agreement or the transactions contemplated hereby.

21.          Entire Agreement .  This Agreement, together with the letter from the Underwriters to the Company confirming the written information relating to the Underwriters furnished to the Company by the Underwriters specifically for inclusion in the documents referred to in Section 10(a), represents the entire agreement between the Company and the Underwriters with respect to the preparation of any Preliminary Final Prospectus, the Time of Sale Prospectus, the Final Prospectus, the conduct of the offering and the purchase and sale of the Shares.

22.          Counterparts .  This Agreement may be executed by any one or more of the parties hereto in any number of counterparts, each of which shall be deemed to be an original, but all such counterparts shall together constitute one and the same instrument.

(b)                                                                                  (i)                                      As of the date hereof, when the Final Prospectus is first filed or transmitted for filing pursuant to Rule 424 under the Act, when, prior to the Time of Delivery (as hereinafter defined), any amendment to the Registration Statement becomes effective (including the filing of any document incorporated by reference in the Registration Statement), when any supplement to the Final Prospectus is filed with the Commission, and at the Time of Delivery, (A) the Registration Statement, as amended as of any such time and the Final Prospectus, as amended or supplemented as of any such time, and the Indenture complied and will comply in all material respects with the applicable requirements of the Act, the Trust Indenture Act of 1939, as amended (the “ Trust Indenture Act ”), and the Exchange Act and the respective rules thereunder, (B) the Registration Statement, as amended as of any such time, does not and will not contain

2

any untrue statement of a material fact and does not and will not omit to state any material fact required to be stated therein or necessary in order to make the statements therein not misleading, and (C) the Final Prospectus, as amended or supplemented as of such time, does not and will not contain any untrue statement of a material fact and does not and will not omit to state any material fact required to be stated therein or necessary in order to make the statements therein, in light of the circumstances under which they were made, not misleading; provided , however , that, in the case of each of (A), (B), and (C), the Company makes no representations or warranties as to (x) the parts of the Registration Statement which constitute the Statement of Eligibility and Qualification (Form T-1) under the Trust Indenture Act of the Trustee (the “ Form T-1 ”); (y) the information contained in or omitted from the Registration Statement, the Final Prospectus or any amendment thereof or supplement thereto in reliance upon and in conformity with information furnished in writing to the Company by any Underwriter specifically for use therein; or (z) any statement which does not constitute part of the Registration Statement, the Final Prospectus or any amendment or supplement thereto pursuant to Rule 412(c) under the Act.

(ii)                                   As of the Applicable Time, the Time of Sale Prospectus did not contain any untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary in order to make the statements therein, in light of the circumstances under which they were made, not misleading; provided , however , that the Company makes no representations or warranties as to (A) the information contained in or omitted from the Time of Sale Prospectus in reliance upon and in conformity with information furnished in writing to the Company by any Underwriter specifically for use therein; or (B) any statement which does not constitute part of the Time of Sale Prospectus pursuant to Rule 412(c) under the Act.

(iii)                                The information included in each “issuer free writing prospectus” within the meaning of Rule 433(h) under the Act relating to the Securities (each, an “ Issuer Free Writing Prospectus ”), other than the Final Term Sheet, including those identified in Schedule III hereto, as of its date, did not conflict with the information contained in the Registration Statement, the Time of Sale Prospectus or the Final Prospectus, as of such date.  Each Issuer Free Writing Prospectus, as supplemented by and taken together with the Time of Sale Prospectus did not contain any untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary in order to make the statements therein, in light of the circumstances under which they were made, not misleading; provided , howeve r , that the Company makes no representations or warranties as to (A) the information contained in or omitted from such Issuer Free Writing Prospectus or the Time of Sale Prospectus in reliance upon and in conformity with information furnished in writing to the Company by any Underwriter specifically for use therein; or (B) any statement which does not constitute part of the Time of Sale Prospectus pursuant to Rule 412(c) under the Act.

(c)                                   Each document incorporated by reference in the Registration Statement, the Time of Sale Prospectus or the Final Prospectus, at the time they were, or hereafter are, filed with the Commission, complied or will comply and, at any time when a prospectus relating to the Securities is required to be delivered under the Act in

3

(d)                                  The Company has been since the time of the initial filing of the Registration Statement, and continues to be, a “well-known seasoned issuer” (as defined in Rule 405 under the Act) and has not been, and continues not to be, an “ineligible issuer” (as defined in Rule 405 under the Act), in each case at all times relevant under the Act in connection with the offering of the Securities.  Any free writing prospectus that the Company is required to file pursuant to Rule 433(d) under the Act has been, or will be, filed with the Commission in accordance with the requirements of the Act and the applicable rules and regulations of the Commission thereunder.  Each Issuer Free Writing Prospectus that the Company has filed, or is required to file, pursuant to Rule 433(d) under the Act or that was prepared by or on behalf of or used by the Company complies or will comply in all material respects with the requirements of the Act and the applicable rules and regulations of the Commission thereunder.  Except for the Issuer Free Writing Prospectuses, if any, identified in Schedules II and III hereto, and electronic road shows each furnished to you before first use, the Company has not prepared, used or referred to, and will not, without your prior consent, prepare, use or refer to any free writing prospectus.

(e)                                   The Company has been duly incorporated, is validly existing as a corporation in good standing under the laws of the jurisdiction of its incorporation, has the corporate power and authority to own its property and to conduct its business as described in the Time of Sale Prospectus and the Final Prospectus and is duly qualified to transact business and is in good standing in each jurisdiction in which the conduct of its business or its ownership or leasing of property requires such qualification, except to the extent that the failure to be so qualified or be in good standing would not have a material adverse effect on the Company and its subsidiaries, taken as a whole.

(f)                                    Each subsidiary of the Company listed in Schedule IV hereto (each, a “ Principal Subsidiary ”) has been duly incorporated, is validly existing as an insurance company or a corporation, as the case may be, in good standing under the laws of the jurisdiction of its incorporation, has the corporate power and authority to own its property and to conduct its business as described in the Time of Sale Prospectus and the Final Prospectus and is duly qualified to transact business and is in good standing in each jurisdiction in which the conduct of its business or its ownership or leasing of property requires such qualification, except to the extent that the failure to be so qualified or be in good standing would not have a material adverse effect on the Company and its subsidiaries, taken as a whole.  The Principal Subsidiaries are currently the only operating insurance companies that are “significant subsidiaries” of the Company as that term is defined in Rule 1-02(w) of Regulation S-X of the rules and regulations of the Commission under the Act.

(g)                                   All of the issued shares of capital stock of each Principal Subsidiary have been duly and validly authorized and issued, are fully paid and nonassessable, and are owned of record directly or indirectly by the Company or another Principal Subsidiary, as the case may be, free and clear of any security interest, claim, lien or encumbrance.

(h)                                  Each Principal Subsidiary is duly licensed or authorized as an insurer or reinsurer in each jurisdiction where it is required to be so licensed or authorized, except where the failure to be so licensed or authorized in any such jurisdiction does not have a material adverse effect on the financial condition, business or properties of the Company and its subsidiaries taken as a whole; the Company and each Principal Subsidiary have made all required filings under applicable insurance holding company statutes, and each is duly licensed or authorized as an insurance holding company in each jurisdiction where it is required to be so licensed or authorized, except where the failure to have made such filings or to be so licensed or authorized in any such jurisdiction does not have a material adverse effect on the financial condition, business or properties of the Company and its subsidiaries taken as a whole; the Company and each Principal Subsidiary have all necessary authorizations, approvals, orders, consents, registrations or qualifications of and from all insurance regulatory authorities to conduct their respective businesses as described in the Time of Sale Prospectus and the Final Prospectus, except where the failure to have such authorizations, approvals, orders, consents, registrations or qualifications does not have a material adverse effect on the financial condition, business or properties of the Company and its subsidiaries taken as a whole; and none of the Company or any Principal Subsidiary has received any notification from any insurance regulatory authority to the effect that any additional authorization, approval, order, consent, registration or qualification from such insurance regulatory authority is needed to be obtained by any of the Company or any Principal Subsidiary in any case where it could be reasonably expected that (x) the Company or any Principal Subsidiary would in fact be required either to obtain any such additional authorization, approval, order, consent, registration or qualification or cease or otherwise limit writing certain business and (y) obtaining such authorization, approval, order, consent, license, certificate, permit, registration or qualification or limiting such business would have a material adverse effect on the business, financial position or results of operations of the Company and its subsidiaries, taken as a whole.

(i)                                      Each Principal Subsidiary is in compliance with the requirements of the insurance laws and regulations of its state of incorporation and the insurance laws and regulations of other jurisdictions which are applicable to such Principal Subsidiary, and has filed all notices, reports, documents or other information required to be filed thereunder, except where the failure to so comply or file would not have a material adverse effect on the business, financial position or results of operations of the Company and its subsidiaries, taken as a whole.

(j)                                     Other than as set forth in the Time of Sale Prospectus and the Final Prospectus, there are no legal or governmental proceedings pending to which the Company or any of its subsidiaries is a party or to which any property of the Company or any of its subsidiaries is the subject which, if determined adversely to the Company or any of its subsidiaries, individually or in the aggregate, could reasonably be expected to have a material adverse effect on the financial condition, business or properties of the Company and its subsidiaries taken as a whole; and, to the best of the Company’s knowledge, no such proceedings are threatened.

(l)                                      The Indenture has been duly qualified under the Trust Indenture Act and has been duly authorized, executed and delivered by the Company and is a valid and binding agreement of the Company, enforceable in accordance with its terms except as (i) the enforceability thereof may be limited by bankruptcy, insolvency or similar laws affecting creditors’ rights generally and (ii) rights of acceleration and the availability of equitable remedies may be limited by equitable principles of general applicability.

(m)                              The Securities have been duly authorized and, when the Securities are issued and delivered pursuant to this Agreement, such Securities will have been duly executed, authenticated, issued and delivered and will constitute valid and legally binding obligations of the Company entitled to the benefits provided by the Indenture.

(n)                                  The issuance and sale of the Securities and compliance by the Company with all of the provisions of the Securities, the Indenture and this Agreement will not conflict with or result in a breach or violation of any of the terms or provisions of, or constitute a default under, any indenture, mortgage, deed of trust, loan agreement or other agreement or instrument for borrowed money to which the Company or any Principal Subsidiary is a party or by which the Company or any of its Principal Subsidiaries is bound or to which any of the property or assets of the Company or any of its Principal Subsidiaries is subject, nor will such action result in any violation of the provisions of the Restated Certificate of Incorporation or Amended and Restated Bylaws of the Company or the organizational documents of any of its Principal Subsidiaries or any statute or any order, rule or regulation of any court or insurance regulatory authority or other governmental agency or body having jurisdiction over the Company or any of its Principal Subsidiaries or any of their properties, in each case other than such breaches, conflicts, violations or defaults which, individually or in the aggregate, would not have a material adverse effect on the Company and its subsidiaries taken as a whole, and no authorization, approval, order, consent, registration or qualification of or with any such court or insurance regulatory authority or other governmental agency or body is required for the issuance or sale of the Securities, except such authorizations, approvals, orders, consents, registrations or qualifications as may be required under state or foreign securities or Blue Sky laws in connection with the purchase and distribution of the Securities by the Underwriters, in each case other than such authorizations, approvals, orders, consents, registrations or qualifications which (individually or in the aggregate) the failure to make, obtain or comply with would not have a material adverse effect on the Company and its subsidiaries, taken as a whole.

(o)                                  Except as described in or contemplated by the Registration Statement, the Time of Sale Prospectus and the Final Prospectus, there has not been any material adverse change in, or any adverse development which materially affects, the business, properties, financial condition or results of operations of the Company and its subsidiaries taken as a whole from the dates as of which information is given in the Registration Statement, the Time of Sale Prospectus and the Final Prospectus; and, since the respective dates as of which information is given in the Registration Statement, the

6

Time of Sale Prospectus and the Final Prospectus, there has not been any material increase in the consolidated capital stock (other than issuances of capital stock upon exercise of options and stock appreciation rights, upon earn-outs of performance shares and upon conversions of convertible securities, in each case which were outstanding on the date of the latest balance sheet incorporated by reference in the Time of Sale Prospectus and the Final Prospectus) or any material increase in the consolidated long-term debt of the Company and its subsidiaries or any material adverse change, or any development involving a prospective material adverse change, in or affecting the general affairs, management, financial position, stockholders’ equity or results of operations of the Company and its subsidiaries, taken as a whole, otherwise than as set forth or contemplated in the Time of Sale Prospectus and the Final Prospectus.

(p)                                  The Company is not, and after giving effect to the offering and sale of the Securities and the application of the net proceeds therefrom as described in the Time of Sale Prospectus and the Final Prospectus, will not be an “investment company” or an entity “controlled” by an “investment company,” as such terms are defined in the Investment Company Act of 1940, as amended.

(r)                                     Except as disclosed in the Time of Sale Prospectus and the Final Prospectus, during the fiscal year ended December 31, 2017, there were no changes in the Company’s internal control over financial reporting that have materially affected, or are reasonably likely to materially affect, the Company’s internal control over financial reporting.

(s)                                    The Company maintains disclosure controls and procedures (as such term is defined in Rule 13a-15(e) under the Exchange Act) that are effective in providing reasonable assurance that material information required to be disclosed in its reports filed with or submitted to the Commission under the Exchange Act is made known to management, including the Company’s principal executive officer and the Company’s principal financial officer, as appropriate to allow timely decisions regarding required disclosure.

(i)                                      Not to take, directly or indirectly, any action designed to or that would constitute or that might reasonably be expected to cause or result in, under the Exchange Act or otherwise, stabilization or manipulation of the price of any security of the Company to facilitate the sale or resale of the Securities; and

8.                                       Reimbursement of Underwriters’ Expenses .  If the sale of the Securities provided herein is not consummated because any condition to the obligations of the Underwriters set forth in Section 7 (other than Section 7(d)) hereof is not satisfied, because of any termination pursuant to Section 12(i) hereof or because of any refusal, inability or failure by the Company to perform any agreement herein or comply with any provision hereof other than by reason of a default by any of the Underwriters, the Company will reimburse the Underwriters severally through the Representatives on demand for all reasonable out-of-pocket expenses (including reasonable fees and disbursements of counsel) that shall have been incurred by them in connection with the proposed purchase and sale of the Securities.

9.                                       Covenants of the Underwriters; Offering Restrictions .

(a)                                  Each Underwriter represents and agrees that, without the prior consent of the Company and the Representatives, other than (x) the Final Term Sheet and (y) one or more term sheets relating to the Securities containing customary information and conveyed to purchasers of Securities and that would not constitute an Issuer Free Writing Prospectus, it has not made and will not make any offer relating to the Securities that would constitute a free writing prospectus.  The Underwriters acknowledge and agree that, except for information consistent in all material respects with the Final Term Sheet

13

and except as may be set forth in Schedule II or III, the Company has not authorized or approved any “issuer information” (as defined in Rule 433(h) under the Act) for use in any free writing prospectus prepared by or on behalf of the Underwriters.

(b)                                  Each Underwriter acknowledges, represents and agrees that it has not offered, sold or delivered and it will not offer, sell or deliver, any of the Securities, in or from any jurisdiction, including those jurisdictions set forth on Schedule VIII, except under circumstances that are reasonably designed to result in compliance with the applicable securities laws and regulations thereof.

10.                                Indemnification and Contribution .

(a)                                  The Company agrees to indemnify and hold harmless each Underwriter, the directors, officers, employees and agents of each Underwriter and each person who controls any Underwriter, within the meaning of either the Act or the Exchange Act, against any and all losses, claims, damages or liabilities, joint or several, to which they or any of them may become subject under the Act, the Exchange Act or other Federal or state statutory law or regulation, at common law or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) (i) arise out of or are based upon any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement as originally filed or in any amendment thereof or arise out of or are based upon the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading or (ii) arise out of or are based upon any untrue statement or alleged untrue statement of a material fact contained in the Basic Prospectus, any Preliminary Final Prospectus, the Time of Sale Prospectus, the Final Prospectus or any Issuer Free Writing Prospectus, including those set forth on Schedule II or III hereof or arise out of or are based upon the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading.  The Company agrees to reimburse each such indemnified party, as incurred, for any legal or other expenses reasonably incurred by them in connection with investigating or defending any such loss, claim, damage, liability or action; provided, however, that the Company will not be liable in any such case arising in connection with this Section 10 to the extent that any such loss, claim, damage or liability (or action in respect thereof) arises out of or is based upon any such untrue statement or alleged untrue statement or omission or alleged omission made therein in reliance upon and in conformity with written information furnished to the Company by or on behalf of any Underwriter specifically for inclusion therein.  This indemnity agreement will be in addition to any liability which the Company may otherwise have.

(b)                                  Each Underwriter, severally and not jointly, agrees to indemnify and hold harmless the Company, each of its directors, each of its officers who signs the Registration Statement, and each person who controls the Company within the meaning of either the Act or the Exchange Act, to the same extent as the foregoing indemnity from the Company to each Underwriter, but only with reference to written information furnished to the Company by or on behalf of such Underwriter specifically for inclusion

14

in the documents referred to in the foregoing indemnity.  This indemnity agreement will be in addition to any liability which any Underwriter may otherwise have.

(c)                                   Promptly after receipt by an indemnified party under this Section 10 of notice of the commencement of any action, such indemnified party will, if a claim in respect thereof is to be made against the indemnifying party under this Section 10, notify the indemnifying party in writing of the commencement thereof; but the failure so to notify the indemnifying party: (i) will not relieve the indemnifying party from liability under paragraph (a) or (b) above unless and to the extent it did not otherwise learn of such action and such failure results in the forfeiture by the indemnifying party of substantial rights and defenses; and (ii) will not, in any event, relieve the indemnifying party from any obligations to any indemnified party other than the indemnification obligation provided in paragraph (a) or (b) above.  The indemnifying party shall be entitled to appoint counsel of the indemnifying party’s choice at the indemnifying party’s expense to represent the indemnified party in any action for which indemnification is sought (in which case the indemnifying party shall not thereafter be responsible for the fees and expenses of any separate counsel retained by the indemnified party or parties except as set forth below) and to participate in and assume the defense of the claim associated with such action; provided, however, that such counsel shall be satisfactory to the indemnified party.  Notwithstanding the indemnifying party’s election to appoint counsel to represent the indemnified party in an action, the indemnified party shall have the right to employ separate counsel (including local counsel), and the indemnifying party shall bear the reasonable fees, costs and expenses of such separate counsel if: (A) the use of counsel chosen by the indemnifying party to represent the indemnified party would present such counsel with a conflict of interest; (B) the actual or potential defendants in, or targets of, 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; (C) the indemnifying party shall not have employed counsel satisfactory to the indemnified party to represent the indemnified party within a reasonable time after notice of the institution of such action; or (D) the indemnifying party shall authorize the indemnified party to employ separate counsel at the expense of the indemnifying party.  An indemnifying party will not, without the prior written consent of the indemnified parties, settle or compromise, or consent to the entry of any judgment with respect to any pending or threatened claim, action, suit or proceeding in respect of which indemnification or contribution may be sought hereunder (whether or not the indemnified parties are actual or potential parties to such claim or action), unless such settlement, compromise or consent (x) includes an unconditional release of each indemnified party from all liability arising out of such claim, action, suit or proceeding and (y) 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.

(d)                                  In the event that the indemnity provided in paragraph (a) or (b) of this Section 10 is unavailable to, or insufficient to hold harmless, an indemnified party for any reason, the Company and the Underwriters severally agree to contribute to the aggregate losses, claims, damages and liabilities (including legal or other expenses reasonably

15

incurred in connection with investigating or defending same) (collectively “Losses”) to which the Company and one or more of the Underwriters may be subject in such proportion as is appropriate to reflect the relative benefits received by the Company, on the one hand, and by the Underwriters, on the other, from the offering of the Securities; provided, however, that in no case shall any Underwriter (except as may be provided in any agreement among underwriters relating to the offering of the Securities) be responsible for any amount in excess of the total price at which the applicable Securities underwritten by it and distributed to the public were offered to the public.  If the allocation provided by the immediately preceding sentence is unavailable for any reason, the Company and the Underwriters severally shall contribute in such proportion as is appropriate to reflect not only such relative benefits but also the relative fault of the Company, on the one hand, and of the Underwriters, on the other, in connection with the statements or omissions which resulted in such Losses as well as any other relevant equitable considerations.  Benefits received by the Company shall be deemed to be equal to the total net proceeds from the offering (before deducting expenses) received by it, and benefits received by the Underwriters shall be deemed to be equal to the total underwriting discounts and commissions, in each case as set forth on the cover page of the Final Prospectus.  Relative fault shall be determined by reference to, among other things: (i) whether any untrue or any alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information provided by the Company, on the one hand, or the Underwriters, on the other; (ii) the intent of the parties and their relative knowledge; (iii) access to information; and (iv) the opportunity to correct or prevent such untrue statement or omission.  The Company and the Underwriters agree that it would not be just and equitable if contribution were determined by pro rata allocation or any other method of allocation which does not take account of the equitable considerations referred to above.  Notwithstanding the provisions of this paragraph (d), no person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation.  For purposes of this Section 10, each person who controls an Underwriter within the meaning of either the Act or the Exchange Act and each director, officer, employee and agent of an Underwriter shall have the same rights to contribution as such Underwriter, and each person who controls the Company within the meaning of either the Act or the Exchange Act, each officer of the Company who shall have signed the Registration Statement and each director of the Company shall have the same rights to contribution as the Company, subject in each case to the applicable terms and conditions of this paragraph (d).

11.                                Defaulting Underwriters .  If any one or more Underwriters shall fail to purchase and pay for any of the Securities agreed to be purchased by the Underwriter or Underwriters hereunder and such failure to purchase shall constitute a default in the performance of its obligations under this Agreement, the remaining Underwriters shall be obligated severally to take up and pay for (in the respective proportions which the amount of Securities set forth opposite their names on Schedule I hereto bears to the aggregate amount of Securities set forth opposite the names of all the remaining Underwriters) the Securities which the defaulting Underwriter or Underwriters agreed but failed to purchase; provided , however , that in the event that the aggregate amount of Securities which the defaulting Underwriter or Underwriters agreed but failed to purchase shall exceed 10% of the aggregate amount of Securities set forth on

16

Schedule I hereto, the remaining Underwriters shall have the right to purchase all, but shall not be under any obligation to purchase any, of the Securities and if such non-defaulting Underwriters do not purchase all the Securities this Agreement will terminate without any liability to any non-defaulting Underwriter or the Company.  In the event of a default by any Underwriter as set forth in this Section 11, the Time of Delivery shall be postponed for such period, not exceeding five Business Days, as the Representatives shall determine in order that the required changes to the Registration Statement, the Time of Sale Prospectus, and the Final Prospectus (including by means of a free writing prospectus) or in any other documents or arrangements may be effected.  Nothing contained in this Agreement shall relieve any defaulting Underwriter of its liability, if any, to the Company and any non-defaulting Underwriter for damages occasioned by its default hereunder.

12.                                Termination .  This Agreement is subject to termination in the absolute discretion of the Representatives, by notice given to the Company prior to delivery of and payment for the Securities, if at any time prior to such time (i) trading in the Company’s securities shall have been suspended by the Commission, (ii) trading in securities generally on the New York Stock Exchange shall have been suspended or limited or minimum prices shall have been established on such Exchange, (iii) a banking moratorium shall have been declared either by Federal or New York State authorities or (iv) there shall have occurred any outbreak or escalation of hostilities, declaration by the United States of a national emergency or war, or other calamity or crisis the effect of which on financial markets is such as to make it, in the sole judgment of the Representatives, impractical or inadvisable to proceed with the offering or delivery of the Securities as contemplated by the Time of Sale Prospectus or the Final Prospectus (exclusive of any supplements thereto).

13.                                Representations and Indemnities to Survive .  The respective agreements, representations, warranties, indemnities and other statements of the Company or its officers and of the several Underwriters set forth in or made pursuant to this Agreement will remain in full force and effect, regardless of any investigation made by or on behalf of any Underwriter or the Company or any of the officers, directors, employees, agents or controlling persons referred to in Section 10 hereof, and will survive the delivery of and payment for the Securities.  The provisions of Sections 8 and 10 hereof shall survive the termination or cancellation of this Agreement.

14.                                Notices .  All communications hereunder will be in writing and effective only on receipt, and, if sent to the Representatives, will be mailed, delivered or telefaxed to J.P. Morgan Securities LLC, 383 Madison Avenue, New York, New York 10179, Attention: Investment Grade Syndicate Desk, 3 rd  Floor, facsimile number (212) 834-6081; Merrill Lynch, Pierce, Fenner & Smith Incorporated, 50 Rockefeller Plaza, NY1-050-12-01, New York, New York 10020, facsimile number (212) 901-7881, Attention: High Grade Debt Capital Markets Transaction Management/Legal; Morgan Stanley & Co.

15.                                Successors and Assigns .  This Agreement will inure to the benefit of and be binding upon the parties hereto and their respective successors and the officers, directors, employees, agent and controlling persons referred to in Section 10 hereof, and no other person will have any right or obligation hereunder.  No purchaser of any of the Securities from any Underwriter shall be deemed a successor or assignee by reason merely of such purchase.

16.                                Time; “Business Day” .  As used herein, the term “business day” shall mean any day other than a Saturday, Sunday or a legal holiday or a day on which banking institutions or trust companies are authorized or obligated by law to close in New York City.

17.                                Fiduciary Duties .  The Company acknowledges that in connection with the offering of the Securities: (a) the Underwriters have acted at arms length, are not agents of, and owe no fiduciary duties to, the Company or any other person, (b) the Underwriters owe the Company only those duties and obligations set forth in this Agreement and prior written agreements (to the extent not superseded by this Agreement), if any, and (c) the Underwriters may have interests that differ from those of the Company.  The Company waives to the full extent permitted by applicable law any claims it may have against the Underwriters arising from an alleged breach of fiduciary duty in connection with the offering of the Securities.

18.                                Patriot Act . In accordance with the requirements of the USA Patriot Act (Title III of Pub. L. 107-56 (signed into law October 26, 2001)), the Underwriters are required to obtain, verify and record information that identifies their respective clients, including the Company, which information may include the name and address of their respective clients, as well as other information that will allow the Underwriters to properly identify their respective clients.

19.                                GOVERNING LAW .  THIS AGREEMENT SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE INTERNAL LAWS OF THE STATE OF NEW YORK.

20.                                Waiver of Jury Trial .  Each of the Company (on its behalf and, to the extent permitted by applicable law, on behalf of its stockholders and affiliates) and the Underwriters hereby irrevocably waives, to the fullest extent permitted by applicable law, any and all right to trial by jury in any legal proceeding arising out of or relating to this Agreement or the transactions contemplated hereby.

21.                                Entire Agreement .  This Agreement, together with the letter from the Underwriters to the Company confirming the written information relating to the Underwriters furnished to the Company by the Underwriters specifically for inclusion in the documents referred to in Section 10(a), represents the entire agreement between the Company and the Underwriters with respect to the preparation of any Preliminary Final Prospectus, the Time of Sale Prospectus, the Final Prospectus, the conduct of the offering and the purchase and sale of the Securities.

Pursuant to Section 7(f) of the Underwriting Agreement, the accountants shall furnish letters to the Underwriters to the effect that:

(a)                                  They are an independent registered public accounting firm with respect to the Company and its subsidiaries within the meaning of the Act, the Exchange Act and the Public Company Accounting Oversight Board and the applicable published rules and regulations thereunder;

(b)                                  In their opinion, the financial statements and financial statement schedules, certain summary and selected consolidated financial and operating data, and any supplementary financial information and schedules (and, if applicable, pro forma financial information) audited by them and included or incorporated by reference in the Time of Sale Prospectus, the Final Prospectus or the Registration Statement comply as to form in all material respects with the applicable accounting requirements of the Act and the Exchange Act and the related published rules and regulations thereunder; and, they have performed a review in accordance with the procedures specified by The Public Company Accounting Oversight Board (“PCAOB”) for a review of interim financial information as described in PCAOB AU 722, Interim Financial Information, of the unaudited consolidated interim financial statements, and any supplementary financial information and schedules, selected financial data, pro forma financial information, prospective financial statements and/or condensed financial statements derived from audited financial statements of the Company included or incorporated by reference in the Time of Sale Prospectus, Final Prospectus, as amended or supplemented, or the Registration Statement, for the periods specified in such letter, and, as indicated in their report thereon, copies of which have been furnished to the representatives of the Underwriters (the “ Representatives ”);

(c)                                   On the basis of limited procedures, not constituting an audit in accordance with generally accepted auditing standards, consisting of a reading of the unaudited financial statements and other information referred to below, a reading of the latest available interim and annual financial statements of the Company and its subsidiaries, inspection of the minute books of the Company and its subsidiaries since the date of the latest audited financial statements included or incorporated by reference in the Time of Sale Prospectus or Final Prospectus as amended or supplemented, inquiries of officials of the Company and its subsidiaries responsible for financial and accounting matters and such other inquiries and procedures as may be specified in such letter, nothing came to their attention that caused them to believe that:

(i)                                      the unaudited consolidated statements of income, consolidated balance sheets and consolidated statements of cash flows and certain summary and selected consolidated financial and operating data included or incorporated by reference in the Time of Sale Prospectus or the Final Prospectus as amended or supplemented do not comply as to form in all material respects with the applicable accounting requirements of the Act and the Exchange Act and the related published rules and regulations thereunder and generally accepted accounting principles, applied on a basis substantially consistent with that of the audited financial statements included or incorporated by reference in the Time of Sale Prospectus or the Final Prospectus;
