Dear Sirs and Mesdames:

Xxxxx & XxXxxxxx Companies, Inc., a Delaware corporation (the “Company”), proposes to issue and sell to each of the Underwriters named in Schedule I hereto (collectively, the “Underwriters”) for whom Xxxxxxx Xxxxx, Xxxxxx, Xxxxxx & Xxxxx Incorporated and Xxxxxxx, Xxxxx & Co. are acting as representatives (in such capacity, the “Representatives”), $600,000,000 aggregate principal amount of 3.750% Senior Notes due 2026 (the “Notes”), to be issued under an indenture dated as of July 15, 2011 (the “Original Indenture”) and a seventh supplemental indenture relating to the Notes to be dated the Closing Date (the “Supplemental Indenture”, and, together with the Original Indenture, the “Indenture”), between the Company, as issuer, and The Bank of New York Mellon, as trustee (the “Trustee”).

On August 7, 2015, the Company filed with the Securities and Exchange Commission (the “Commission”) a registration statement on Form S-3 (No. 333-206217) for the registration of the offer and sale of certain securities, including the Notes, from time to time in accordance with Rule 415 under the Securities Act of 1933, as amended (the “Securities Act”), and the Company has filed such post-effective amendments thereto as may be required prior to the date hereof. Such registration statement, as so amended, has been declared effective by the Commission, and the Indenture has been qualified under the Trust Indenture Act of 1939, as amended (the “Trust Indenture Act”). The Company has furnished to you, for use by the Underwriters and by dealers, electronic copies of one or more preliminary prospectus supplements (the “Preliminary Prospectus Supplements”) relating to the Notes. Promptly after execution and delivery of this Agreement, the Company will prepare and file a final prospectus supplement (the “Final Prospectus Supplement”) reflecting the terms of the Notes,

the terms of the offering thereof and the other matters set forth therein, pursuant to Rule 424(b) under the Securities Act. The registration statement, in the form in which it became effective and all post-effective amendments thereto, is herein called the “Registration Statement”. The prospectus dated August 7, 2015, in the form in which it appears in the Registration Statement is hereinafter referred to as the “Basic Prospectus”. The term “Preliminary Prospectus” shall mean any Preliminary Prospectus Supplement relating to the Notes, together with the Basic Prospectus, that is filed with the Commission pursuant to Rule 424(b). The term “Prospectus” shall mean the final prospectus supplement relating to the Notes, together with the Basic Prospectus, that is filed pursuant to Rule 424(b) after the date and time that this Agreement is executed (the “Execution Time”) by the parties hereto. If the Company has filed an abbreviated registration statement to register additional Notes or other debt securities pursuant to Rule 462(b) under the Securities Act (the “Rule 462 Registration Statement”), then any reference herein to the term “Registration Statement” shall be deemed to include such Rule 462 Registration Statement. Any reference in this Agreement to the Registration Statement, the Basic Prospectus, the Preliminary Prospectus and the Prospectus shall be deemed to refer to and include the documents incorporated by reference therein pursuant to Item 12 of Form S-3 under the Securities Act, prior to 3:40 p.m. on the date of this Agreement (the “Initial Sale Time”), and any reference to “amend”, “amendment” or “supplement” with respect to the Registration Statement, the Prospectus, the Basic Prospectus, the Preliminary Prospectus Supplements and the Final Prospectus Supplement shall be deemed to refer to and include any documents filed after the Initial Sale Time under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), and the rules and regulations of the Commission thereunder that are deemed to be incorporated by reference therein.

1. Representations and Warranties of the Company. The Company represents and warrants to and agrees with the Representatives that:

(i) The Registration Statement has become effective; no stop order suspending the effectiveness of the Registration Statement is in effect, and no proceedings for such purpose are pending before or, to the knowledge of the Company, threatened by the Commission.

(ii) At the respective times the Registration Statement and any post-effective amendments thereto became effective or were filed, as the case may be, at the date hereof and at the Closing Date (as defined in Section 4 hereof), the Registration Statement and any amendments thereto did not, do not and will not contain any 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, and complied, comply and will comply in all material respects with the Securities Act and the applicable rules and regulations of the Commission thereunder. At the date of the Prospectus and at the Closing Date, neither the Prospectus nor any amendment or supplement thereto contained or contains and, as amended or supplemented, if applicable, will contain any 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 under which they were made, not misleading, except that the representations and warranties set forth in this paragraph do not apply to statements or omissions in the Registration Statement or the Prospectus or any amendment or supplement thereto based upon and in conformity with written information furnished to the Company by any Underwriter through the Representatives expressly for use

therein, it being understood and agreed that the only such information furnished by any Underwriter through the Representatives consists of the information described as such in Section 7 hereof.

(iii) The term “Disclosure Package” shall mean (i) the Preliminary Prospectus dated September 9, 2015, (ii) the issuer free writing prospectuses as defined in Rule 433 under the Securities Act (each, an “Issuer Free Writing Prospectus”), if any, identified in Schedule II hereto and (iii) any other free writing prospectus that the parties hereto shall hereafter expressly agree in writing to treat as part of the Disclosure Package. As of the Initial Sale Time, the Disclosure Package did not contain any untrue statement of a material fact or omit to state any material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading. The representations and warranties set forth in this paragraph do not apply to statements or omissions in the Disclosure Package based upon and in conformity with written information furnished to the Company by any Underwriter through the Representatives expressly for use therein, it being understood and agreed that the only such information furnished by any Underwriter through the Representatives consists of the information described as such in Section 7 hereof.

(v) (i) At the time of filing the Registration Statement and (ii) as of the Execution Time (with such date being used as the determination date for purposes of this Section 1(v)), the Company was not and is not an Ineligible Issuer (as defined in Rule 405 under the Securities Act).

(vii) Each Issuer Free Writing Prospectus, as of its issue date and at all subsequent times through the completion of the offering of Notes under this Agreement or until any earlier date that the Company notified or notifies the Representatives as described in the next sentence, did not, does not and will not include any information that conflicted, conflicts or will conflict with the information contained in the Registration Statement, the Preliminary Prospectus or the Prospectus. If at any time following issuance of an Issuer Free Writing Prospectus there occurred or occurs an event or development as a result of which such Issuer Free Writing Prospectus conflicted or would conflict with the information contained in the Registration Statement, the Preliminary Prospectus or the Prospectus, the Company has promptly notified or will promptly notify the Representatives and has promptly amended or supplemented or will promptly amend or supplement, at its own expense, such Issuer Free Writing Prospectus to eliminate or correct such conflict. The representations and warranties set forth in this paragraph do not apply to statements or omissions in the Disclosure Package based upon and in conformity with written information furnished to the Company by any Underwriter through the Representatives expressly for use therein, it being understood and agreed that the only such information furnished by any Underwriter through the Representatives consists of the information described as such in Section 7 hereof.

(viii) The Company has not distributed and will not distribute, prior to the later of the Closing Date and the completion of the Underwriters’ distribution of the Notes, any offering material in connection with the offering and sale of the Notes other than the Preliminary Prospectus, the Prospectus, any Issuer Free Writing Prospectus reviewed and consented to by the Representatives and included in Schedule II hereto or the Registration Statement.

The Supplemental Indenture has been duly and validly authorized by all necessary corporate action by the Company; upon due execution and delivery by the Company, and upon the due authorization, execution and delivery by the Trustee, the Supplemental Indenture will be a valid and binding agreement of the Company, enforceable against the Company in accordance with its terms, subject to applicable bankruptcy, insolvency, reorganization, moratorium, fraudulent conveyance or similar laws now or hereafter in effect affecting creditors’ rights generally and subject, as to enforceability, to general principles of equity (regardless of whether enforcement is considered in a proceeding in equity or at law). The Original Indenture has been duly qualified under the Trust Indenture Act. The Notes and the Indenture will conform, in each case in all material respects, to the descriptions thereof contained in the Disclosure Package and the Prospectus.

(xiii) The issuance and sale of the Notes have been duly and validly authorized by all necessary corporate action by the Company and, when duly executed by the Company and duly authenticated and delivered by the Trustee against payment in accordance with the terms of the Indenture and this Agreement, will be valid and binding obligations of the Company, enforceable against the Company in accordance with their terms (assuming the due authorization, execution and delivery of the Indenture by the Trustee) and entitled to the benefits of the Indenture, subject to applicable bankruptcy, insolvency, reorganization, moratorium, fraudulent conveyance or similar laws now or hereafter in effect affecting creditors’ rights generally and subject, as to enforceability, to general principles of equity (regardless of whether enforcement is considered in a proceeding in equity or at law). When duly executed, authenticated, issued, delivered and paid for as provided herein and in the Indenture, the Notes will constitute direct, general senior, unsecured and unconditional obligations of the Company and will rank pari passu with all other present and future senior, unsecured indebtedness of the Company (other than obligations preferred by statute or operation of law).

(xiv) The execution, delivery and performance by the Company of this Agreement and the Indenture, the issuance, authentication, sale and delivery of the Notes and compliance by the Company with the terms thereof, and the consummation of the transactions contemplated herein and therein, will not conflict with or violate any provision of applicable law or the certificate of incorporation or by-laws of the Company or any agreement or other instrument binding upon the Company or any of its subsidiaries that is material to the Company and its subsidiaries, taken as a whole, or any judgment, order or decree of, or settlement agreement with, any governmental body, agency or court having jurisdiction over the Company or any subsidiary, except for any such conflicts or violations which, individually or in the aggregate, would not reasonably be expected to have a material adverse effect on the Company and its subsidiaries taken as a whole; and no consent, approval, authorization or order of or qualification with, any

governmental body or agency is required for the execution, delivery and performance by the Company of this Agreement or the Indenture, the issuance, authentication, sale and delivery of the Notes and compliance by the Company with the terms thereof, and the consummation of the transactions contemplated by this Agreement or the Indenture, except for the registration of the Notes under the Securities Act, the qualification of the Indenture under the Trust Indenture Act and such consents, approvals, authorizations, filings, registrations or qualifications (A) which shall have been obtained or made prior to the Closing Date and (B) as may be required to be obtained or made under the Exchange Act and applicable state securities laws in connection with the purchase and distribution of the Notes by the Underwriters.

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

(a) To make available to you, without charge, two signed copies of the Registration Statement (including exhibits thereto) and to furnish to you in New York City, without charge, prior to 10:00 a.m. New York City time on the business day next succeeding the date of this Agreement and during the period mentioned in Section 6(c) below, as many copies of the Disclosure Package, the Prospectus and any supplements and amendments thereto or to the Registration Statement as you may reasonably request.

(b) In connection with the offering of the Notes, before amending or supplementing the Disclosure Package or the Prospectus to furnish to you a copy of each such proposed amendment or supplement and (other than solely with respect to the filing of a document pursuant to the Exchange Act) not to file any such proposed amendment or supplement to which you reasonably object, and to file with the Commission within the applicable period specified in Rule 424(b) under the Securities Act any prospectus required to be filed pursuant to such Rule.

(c) The Company will immediately notify the Representatives and their counsel upon becoming aware of any such event, development or condition that may cause the Registration Statement to 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 may cause the Prospectus or Disclosure Package to 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. If at any time during the 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 Notes by an Underwriter or dealer, including in circumstances where such requirement may be satisfied pursuant to Rule 172 under the Securities Act (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 outside counsel 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 Disclosure Package or the Prospectus in order that the Disclosure Package 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 Disclosure Package or the Prospectus to comply with applicable law, the Company will, upon notice from such counsel, promptly prepare and file with the Commission, subject to Section 6(b) hereof, such amendment or supplement as may be necessary to correct such statement or omission or to make the Registration Statement, the Disclosure Package 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.

(d) To endeavor to qualify the Notes for offer and sale under the securities or Blue Sky laws of such jurisdictions as you shall reasonably request, provided that in connection therewith the Company will not be required to (i) qualify as a foreign corporation or file a general consent to service of process in any jurisdiction where it is not now so qualified or required to file such a consent or (ii) subject itself to taxation in respect of doing business in any jurisdiction where it is not currently subject to taxation.

(e) Whether or not the transactions contemplated in this Agreement are consummated or this Agreement is terminated, to pay or cause to be paid all expenses incident to the performance of its obligations under this Agreement, including: the fees, disbursements and expenses of the Company’s outside counsel and the Company’s accountants in connection with the registration and delivery of the Notes under the Securities Act and all other fees or expenses in connection with the preparation and filing of the Disclosure Package, the Prospectus, any Issuer Free Writing Prospectus and amendments and supplements to any of the foregoing, including all printing costs associated therewith, and the mailing and delivering of copies thereof to the Underwriters and dealers, in the quantities hereinabove specified, all costs and expenses related to the transfer and delivery of the Notes to the Underwriters, including any transfer or other taxes payable thereon, the cost of printing or producing any Blue Sky memorandum in connection with the offer and sale of the Notes under state securities laws and all expenses in connection with the qualification of the Notes for offer and sale under state securities laws as provided in Section 6(d) hereof, including filing fees and the reasonable fees and disbursements of counsel for the Underwriters in connection with such qualification and in connection with the Blue Sky memorandum, all filing fees and the reasonable fees and disbursements of counsel to the Underwriters incurred in connection with the review and qualification of the offering of the Notes by the Financial Industry Regulatory Authority, Inc., the cost of printing the Notes, the costs and charges of the Trustee, the costs and expenses of the Company relating to investor presentations on any

It is understood, however, that except as provided in this Section, Section 7 entitled “Indemnity and Contribution”, and the last paragraph of Section 9 below, each Underwriter will pay all of its costs and expenses in connection with the resale of any of the Notes by it and any advertising expenses connected with any offers it may make.

(f) The Company will file the term sheet attached at Schedule II hereto (the “Final Term Sheet”) pursuant to Rule 433(d) under the Securities Act within the time required by such rule.

(g) 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 Notes that would constitute an Issuer Free Writing Prospectus or that would otherwise constitute a “free writing prospectus” (as defined in Rule 405 under the Securities Act) required to be filed by the Company with the Commission or retained by the Company under Rule 433 under the Securities Act; 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 II 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 under the Securities Act 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 Notes or their offering, (ii) information permitted by Rule 134 under the Securities Act or (iii) information that describes the final terms of the Notes or their offering and that is included in the Final Term Sheet of the Company contemplated in Section 6(f).

(h) 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 Notes, 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 reasonably necessary or appropriate to permit the public offering and sale of the Notes 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.

(i) The Company agrees to pay the required Commission filing fees relating to the Notes within the time required by and in accordance with Rule 456(b)(1) and 457(r) under the Securities Act.

7. Indemnity and Contribution.

(a) The Company agrees to indemnify and hold harmless each Underwriter and each person, if any, who controls any Underwriter within the meaning of either Section 15 of the Securities Act or Section 20 of the Exchange Act, from and against any and all losses, claims, damages and liabilities (including, without limitation, any legal or other expenses reasonably incurred in connection with defending or investigating any such action or claim) caused by any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement or any amendment thereof, any Preliminary Prospectus, any Issuer Free Writing Prospectus or the Prospectus or any amendments or supplements thereto, or caused by any omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, except insofar as such losses, claims, damages or liabilities are caused by any such untrue statement or omission or alleged untrue statement or omission based upon information relating to any Underwriter furnished to the Company in writing by or on behalf of any Underwriter through the Representatives expressly for use therein.

(b) Each Underwriter severally agrees to indemnify and hold harmless the Company, its directors, its officers who signed the Registration Statement and each person, if any, who controls the Company within the meaning of either Section 15 of the Securities Act or Section 20 of the Exchange Act to the same extent as the indemnity contained in subsection (a) of this Section, but only with reference to information relating to the Underwriters furnished to the Company in writing by or on behalf of any Underwriter through the Representatives expressly for use in the Registration Statement, any Preliminary Prospectus, any Issuer Free Writing Prospectus, the Prospectus or any amendments or supplements thereto. The Company hereby acknowledges that the only information furnished to the Company by any Underwriter through the Representatives expressly for use in the Registration Statement, any Issuer Free Writing Prospectus, the Preliminary Prospectus or the Prospectus (or any amendment or supplement thereto) are the following statements set forth in the “Underwriting” section in the Preliminary Prospectus and the Prospectus: (i) the fourth paragraph relating to concessions and reallowances; and (ii) the eighth, ninth and tenth paragraphs relating to stabilization, syndicate covering transactions and penalty bids.

(c) In case any proceeding (including any governmental investigation) shall be instituted involving any person in respect of which indemnity may be sought pursuant to Section 7(a) or Section 7(b), such person (the “indemnified party”) shall promptly notify the person against whom such indemnity may be sought (the “indemnifying party”) in writing and the indemnifying party, upon request of the indemnified party, shall retain counsel reasonably satisfactory to the indemnified party to represent the indemnified party and any others the indemnifying party may designate in such proceeding and shall pay the fees and disbursements of such counsel related to such proceeding; but the failure so to notify the indemnifying party 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. In any such proceeding, any indemnified party shall have the right to retain its own counsel, but the fees and expenses of such counsel shall be at the expense of such indemnified party unless (i) the indemnifying party and the indemnified party shall have mutually agreed to the retention of such counsel, (ii) the named parties to any such proceeding (including any impleaded parties) include both the indemnifying party and the indemnified party and representation of both parties by the same counsel would be inappropriate due to actual or potential differing interests between them or (iii) the indemnifying party failed to retain satisfactory counsel in a timely manner. It is understood that the indemnifying party shall not, in respect of the legal expenses of any indemnified party in connection with any proceeding or related proceedings in the same jurisdiction, be liable for the fees and expenses of more than one separate firm (in addition to any local counsel) for all such indemnified parties and that all such fees and expenses shall be reimbursed as they are incurred. Any such separate firm for any Underwriter and such control persons of such Underwriter shall be designated in writing by the Representatives in the case of parties indemnified pursuant to Section 7(a); and by the Company, in the case of parties indemnified pursuant to Section 7(b). The indemnifying party shall not be liable for any settlement of any proceeding effected without its written consent, but if settled with such consent or if there be a final judgment for the plaintiff the indemnifying party agrees to indemnify the indemnified party from and against any loss or liability by reason of such settlement or judgment. No indemnifying party shall, without the prior written consent of the indemnified party, effect any settlement of any pending or threatened proceeding in respect of which any indemnified party is or could have been a party and indemnity could have been sought hereunder by such indemnified party, unless such settlement (i) includes an unconditional release of such indemnified party from all liability on claims that are the subject matter of such proceeding 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.

(d) To the extent the indemnification provided for in paragraph (a) or (b) of this Section 7 is unavailable to an indemnified party or insufficient in amount in respect of any losses, claims, damages or liabilities referred to therein, then each indemnifying party under such paragraph, in lieu of indemnifying such indemnified party thereunder, shall contribute to the amount paid or payable by such indemnified party as a result of such losses, claims, damages or liabilities in such proportion as is appropriate to reflect the relative benefits received by the Company on the one hand and the Underwriters on

the other hand from the offering of the Notes or if the allocation provided above is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to above but also the relative fault of the Company on the one hand and of the Underwriters on the other hand in connection with the statements or omissions that resulted in such losses, claims, damages or liabilities, 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 Notes shall be deemed to be in the same respective proportions as the net proceeds from the offering of the Notes (before deducting expenses) received by the Company and the total underwriting discounts and commissions received by the Underwriters, in each case as set forth in the table on the cover of the Prospectus, bear to the aggregate initial public offering price of the Notes as set forth on such cover. The relative fault of the Company on the one hand and the Underwriters on the other hand 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 Company or by the Underwriters and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission.

(e) The Company and the Underwriters agree that it would not be just or equitable if contribution pursuant to this Section 7 were determined by pro rata allocation or by any other method of allocation that does not take account of the equitable considerations referred to in Section 7(d). The amount paid or payable by an indemnified party as a result of the losses, claims, damages and liabilities referred to in the immediately preceding paragraph shall be deemed to include, subject to the limitations set forth above, 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 Sections 7(d) and 7(e), no Underwriter shall be required to contribute any amount in excess of the amount by which the total price at which the Notes underwritten by it and distributed to the public were offered to the public exceeds the amount of any damages that the Underwriter has 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. The remedies provided for in this Section 7 are not exclusive and shall not limit any rights or remedies which may otherwise be available to any indemnified party at law or in equity. The obligations of the Underwriters in this subsection (e) and subsection (d) above, to contribute are several in proportion to their respective underwriting obligations with respect to such Notes and not joint.

(f) The indemnity and contribution provisions contained in this Section 7 and the representations, warranties and other statements of the Company contained in this Agreement shall remain operative and in full force and effect regardless of any termination of this Agreement, any investigation made by or on behalf of the Underwriters or any person controlling the Underwriters or by or on behalf of the Company, its officers who signed the Registration Statement, its directors or any person controlling the Company and acceptance of and payment for any of the Notes.

8. Termination. This Agreement shall be subject to termination by notice given by the Representatives to the Company if after the execution and delivery of this Agreement and prior to the Closing Date, (a) trading generally shall have been suspended or materially limited on or by, as the case may be, the New York Stock Exchange or the Financial Industry Regulatory Authority, (b) trading of any securities of the Company shall have been suspended on any exchange or in any over-the-counter market, (c) a general moratorium on commercial banking activities in New York shall have been declared by either Federal or New York State authorities or (d) there shall have occurred any outbreak or escalation of hostilities or any change in financial markets or any calamity or crisis that, in the Representatives’ judgment, is material and adverse and, in the case of any of the events specified in clauses (a) through (d), such event, singly or together with any other such event, makes it, in the Representatives’ judgment, impracticable or inadvisable to offer, sell or deliver the Notes on the terms and in the manner contemplated in the Disclosure Package.

9. Defaulting Underwriters.

(a) If any Underwriter shall default in its obligations to purchase the Notes which it has agreed to purchase at the Closing Date under this Agreement, the Representatives may in their discretion arrange for themselves or another party or other parties to purchase such Notes on the terms contained herein. If within thirty-six hours after such default by any Underwriter the Representatives do not arrange for the purchase of such Notes, then the Company shall be entitled to a further thirty-six hours within which to procure another party or parties reasonably satisfactory to the Representatives to purchase such Notes on such terms. In the event that, within the respective prescribed period, the Representatives notify the Company that they have so arranged for the purchase of the Notes, or the Company notifies the Representatives that it has so arranged for the purchase of such Notes, the Representatives or the Company shall have the right to postpone the Closing Date for a period of not more than seven days, in order to effect whatever changes may thereby be made necessary in the Registration Statement or the Prospectus, as amended or supplemented, or in any other documents or arrangements, the Company agrees to file promptly any amendments or supplements to the Registration Statement or the Prospectus which in the opinion of the Representatives may thereby be made necessary. The term “Underwriter” as used in this Agreement shall include any person substituted under this Section with like effect as if such person had originally been a party to this Agreement with respect to such Notes.

(b) If, after giving effect to any arrangements for the purchase of the Notes of a defaulting Underwriter or Underwriters by the Representatives and the Company as provided in subsection (a) above, the aggregate principal amount of such Notes which remains unpurchased does not exceed one-eleventh of the aggregate principal amount of the Notes to be purchased on the Closing Date, then the Company shall have the right to require each non-defaulting Underwriter to purchase the principal amount of Notes which such Underwriter has agreed to purchase under this Agreement and, in addition, to require each non-defaulting Underwriter to purchase its pro rata share (based on the principal amount of Notes which such Underwriter agreed to purchase under this Agreement) of the Notes of such defaulting Underwriter or Underwriters for which such arrangements have not been made; but nothing herein shall relieve a defaulting Underwriter from liability for its default.

(c) If, after giving effect to any arrangements for the purchase of the Notes of a defaulting Underwriter or Underwriters by the Representatives and the Company as provided in subsection (a) above, the aggregate principal amount of Notes which remains unpurchased exceeds one-eleventh of the aggregate principal amount of the Notes to be purchased on the Closing Date, as referred to in subsection (b) above, or if the Company shall not exercise the right described in subsection (b) above to require non-defaulting Underwriters to purchase the Notes of a defaulting Underwriter or Underwriters, then this Agreement shall thereupon terminate, without liability on the part of any non-defaulting Underwriter or the Company, except for the expenses to be borne by the Company and the Underwriters as provided in Section 6 hereof and the indemnity and contribution agreements in Section 7 hereof, but nothing herein shall relieve a defaulting Underwriter from liability for its default.

10. Effectiveness. This Agreement shall become effective upon the execution and delivery hereof by the parties hereto.

11. Reimbursement of Underwriters’ Expenses. If this Agreement shall be terminated by the Underwriters because of any failure or refusal on the part of the Company to comply with the terms or to fulfill any of the conditions of this Agreement, or if for any reason the Company shall be unable to perform its obligations under this Agreement, the Company will reimburse the Underwriters for all out-of-pocket expenses reasonably incurred by such Underwriters in connection with this Agreement or the offering contemplated hereunder.

12. Counterparts. This Agreement may be signed in two or more counterparts (including by facsimile), each of which shall be an original, with the same effect as if the signatures thereto and hereto were upon the same instrument.

13. Applicable Law. This Agreement shall be governed by and construed in accordance with the internal laws of the State of New York, without giving effect to the conflicts of laws provisions thereof.

14. Headings. The headings of the sections of this Agreement have been inserted for convenience of reference only and shall not be deemed a part of this Agreement.

15. No Fiduciary Duty. The Company acknowledges and agrees that (a) the purchase and sale of the Notes pursuant to this Agreement is an arm’s-length commercial transaction between the Company, on the one hand, and the several Underwriters, on the other, (b) in connection therewith and with the process leading to such transaction each Underwriter is acting solely as a principal and not the agent or fiduciary of the Company, (c) no Underwriter has assumed an advisory or fiduciary responsibility in favor of the Company with respect to the offering contemplated hereby or the process leading thereto (irrespective of whether such Underwriter has advised or is currently advising the Company on other matters) or any other obligation to the Company except the obligations expressly set forth in this Agreement and (d) the Company has consulted its own legal and financial advisors to the extent it deemed

appropriate. The Company agrees that it will not claim that the Underwriters, or any of them, has rendered advisory services of any nature or respect, or owes a fiduciary or similar duty to the Company, in connection with such transaction or the process leading thereto.

16. Entire Agreement. This Agreement supersedes all prior agreements and understandings (whether written or oral) between the Company and the Underwriters, or any of them, with respect to the subject matter hereof.

17. No Trial by Jury. The Company and each of 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.

18. Patriot Act Compliance. 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.
