(f) The Company represents that neither it nor anyone acting on its behalf has made, and agrees that, unless it obtains the prior written consent of the Underwriters, neither it nor anyone acting on its behalf will make, any offer relating to the Securities that would constitute an Issuer Free Writing Prospectus or that would otherwise constitute a free writing prospectus 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 Underwriters shall be deemed to have been given in respect of each free writing prospectus (as defined in Rule 405), if any, that is attached hereto as (or identified on) Schedule C.  Any such free writing prospectus that is consented to, or is deemed to have been consented to, by the Underwriters is referred to herein 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) it has complied and will comply, as the case may be, with the requirements of Rules 164 and 433 of the 1933 Act Regulations applicable to any Permitted Free Writing Prospectus, including in respect of timely filing with the Commission, legending and record keeping.  The Underwriters agree that, unless they obtain the prior written consent of the Company, the Underwriters will not make any offer relating to the Securities that constitutes or would constitute a free writing prospectus required to be filed with the Commission under Rule 433.  Notwithstanding the foregoing, the Company consents to the use by any Underwriter of a free writing prospectus that (a) is not an Issuer Free Writing Prospectus, and (b) contains only (i) information describing the preliminary terms of the Securities or their offering, (ii) information permitted by Rule 134 or (iii) information that describes the final terms of the Securities or their offering and other customary information relating thereto.

(g) If immediately prior to the third anniversary (the “Renewal Deadline”) of April 27, 2017, any of the Securities remain unsold by the Underwriters, the Company will, prior to the Renewal Deadline, file, if they have not already done so, a new shelf registration statement relating to the Securities in a form satisfactory to the Underwriters, 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 thereto.  References herein to the “Registration Statement” shall include such new shelf registration statement.

(h) The Company will timely file such reports pursuant to the 1934 Act as are necessary in order to make generally available to its securityholders as soon as practicable an earnings statement for the purposes of, and to provide to the Underwriters the benefits contemplated by, the last paragraph of Section 11(a) of the 1933 Act.

(i) The Company will arrange, if necessary, for the qualification of the Securities for sale under the laws of such jurisdictions as the Underwriters may designate, will maintain such qualifications in effect so long as required for the distribution of the Securities and will pay any fee of the Financial Industry Regulatory Authority (“FINRA”), in connection with its review of the offering; provided that in no event shall the Company be obligated to qualify to do business in any jurisdiction where it is not now so qualified or to take any action that would subject it to service of process in suits, other than those arising out of the offering or sale of the Securities, in any jurisdiction where it is not now so subject.  In each jurisdiction in which the Securities have been so qualified, the Company will file such statements and reports as may be required by the laws of such jurisdiction.

Company or such other securities, in cash or otherwise; provided,  however, that the Company may issue, sell, contract to sell or otherwise dispose of or grant options for, shares of any capital stock of the Company or securities convertible into, or exchangeable for, shares of any capital stock of the Company: (1) pursuant to this Agreement; (2) pursuant to any benefit plan, dividend reinvestment plan or 10b5-1 plan of the Company in effect as of the date hereof, including, but not limited to, the Company’s 1999 Long-Term Incentive Plan; (3) pursuant to any warrants, stock options or other convertible securities outstanding as of the date hereof; and (4) as consideration for the acquisition by the Company or one of its subsidiaries from a third party of assets or of equity interests of any other entity which entity would, after giving effect to the acquisition of such equity interests, be a subsidiary of the Company.

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 signed the Registration Statement, and each person who controls the Company within the meaning of either the 1933 Act or the 1934 Act, to the same extent as the foregoing indemnity from the Company to each Underwriter but only with respect to untrue statements or omissions, or alleged untrue statements or omissions, made in the Registration Statement (or any amendment thereto), including the Rule 430B Information, or any preliminary prospectus, any Issuer Free Writing Prospectus, the Disclosure Package or the Prospectus (or any amendment or supplement thereto) in reliance upon and in conformity with written information furnished to the Company by the Underwriters expressly for use therein.

The Company acknowledges that the statements set forth in the second sentence of the first paragraph under the caption “Commissions and Discounts” under the heading “Underwriting” in the Prospectus constitute the only information furnished in writing by or on behalf of the several Underwriters for inclusion in the Registration Statement, the Prospectus and the Disclosure Package or any of the other documents referred to in the foregoing indemnity.

(c) Promptly after receipt by an indemnified party under this Section 8 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 8, notify the indemnifying party in writing of the commencement thereof; but the failure to so notify the indemnifying party (i) will not relieve the indemnifying party from liability under paragraph (a) or (b) of this Section 8 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) of this Section 8. 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); 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 (i) the use of counsel chosen by the indemnifying party to represent the indemnified party would present such counsel with a conflict of interest, (ii) 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 or (iii) 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 (iv) the indemnifying party shall authorize the indemnified party to employ separate counsel at the expense of the indemnifying party. It is understood, however, that the indemnifying party shall, in connection with any one such action or separate but substantially similar or related actions in the same jurisdiction arising out of the same general allegations or circumstances, be liable for the fees and expenses of only one separate firm of attorneys (in addition to any local counsel) at any time for all such indemnified parties, which firm shall be designated in writing by the Underwriters.  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 includes an unconditional release of each indemnified party from all liability arising out of such claim, action, suit or proceeding  and 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 8 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 the 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 underwriting discount or commission applicable to the Securities purchased by such Underwriter hereunder. 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 gross proceeds from the offering (before deducting expenses), and benefits

received by the Underwriters shall be deemed to be equal to the total underwriting discounts and commissions received by the Underwriters pursuant to this Agreement. Relative fault shall be determined by reference to, among other things, 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, the intent of the parties and their relative knowledge, access to information and 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 1933 Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. For purposes of this Section 8, each person who controls an Underwriter within the meaning of either the 1933 Act or the 1934 Act, each director, officer, employee and agent of an Underwriter and each Underwriter’s Affiliates that participates in the distribution of securities shall have the same rights to contribution as such Underwriter, and each person who controls the Company within the meaning of either the 1933 Act or the 1934 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).

9. Default by an Underwriter.  If any Underwriter shall fail to purchase and pay for any of the Securities agreed to be purchased by such Underwriter hereunder and such failure to purchase shall constitute a default in the performance of its obligations under this Agreement, the remaining Underwriter shall be obligated to take up and pay for the Securities which the defaulting Underwriter agreed but failed to purchase; provided,  however, that in the event that the aggregate amount of Securities which the defaulting Underwriter agreed but failed to purchase shall exceed 10% of the aggregate amount of Securities set forth in Schedule A attached hereto, the remaining Underwriter shall have the right to purchase all, but shall not be under any obligation to purchase any, of the Securities, and if such nondefaulting Underwriter does not purchase all the Securities, this Agreement will terminate without liability to any nondefaulting Underwriter or the Company. In the event of a default by any Underwriter as set forth in this Section 9, the Closing Date shall be postponed for such period, not exceeding five New York business days, as the Underwriters shall determine in order that the required changes in the Registration Statement, the Prospectus, the Disclosure Package 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 nondefaulting Underwriter for damages occasioned by its default hereunder.

10. Termination.  This Agreement shall be subject to termination (, in the absolute discretion of the Underwriters, 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 Common Stock shall have been suspended by the Commission or the NYSE or trading in securities generally on either the NYSE or the NASDAQ Stock Market shall have been suspended or limited or minimum prices shall have been established on either of said exchanges, (ii) a banking

moratorium shall have been declared either by Federal or New York State authorities or a material disruption in commercial banking or securities settlement or clearance services in the United States shall have occurred; or (iii) 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 Underwriters, impractical or inadvisable to proceed with the offering or delivery of the Securities as contemplated by the Prospectus (exclusive of any supplement thereto).

11. Representations and Indemnities to Survive. The respective agreements, representations, warranties, indemnities and other statements of the Company or its officers and of the 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 8 hereof, and will survive delivery of and payment for the Securities. The provisions of Sections 7 and 8 hereof shall survive the termination or cancellation of this Agreement.

12. Notices. All notices and other communications hereunder shall be in writing and shall be deemed to have been duly given if mailed or transmitted by any standard form of telecommunication.  Notices to the Underwriters shall be directed to:

13. Recognition of the U.S. Special Recognition Regimes.

Successors.  This Agreement will inure to the benefit of and be binding upon the parties hereto and their respective successors and the officers, directors, employees, agents and controlling persons referred to in Section 8 hereof, and no other person will have any right or obligation hereunder.

15. Applicable Law.  This Agreement and any claim, controversy or dispute relating to or arising out of this Agreement will be governed by and construed in accordance with the laws of the State of New York applicable to contracts made and to be performed within the State of New York.

16. Counterparts. This Agreement may be signed in one or more counterparts, each of which shall constitute an original and all of which together shall constitute one and the same agreement.
