As Representatives of the Initial Purchasers

Ladies and Gentlemen:

Kansas Gas and Electric Company, a corporation organized under the laws of Kansas (the “Company”), proposes to issue and sell to the several parties named in Schedule I hereto (the “Initial Purchasers”), for whom you (the “Representatives”) are acting as representatives, $250,000,000 principal amount of its First Mortgage Bonds, 4.30% Series due 2044 (the “Securities”). The Securities are to be issued under a Mortgage and Deed of Trust, dated as of April 1, 1940 (as heretofore amended and supplemented, the “Original Mortgage”), between the Company and The Bank of New York Mellon Trust Company, N.A. (as successor-in-interest to Guaranty Trust Company of New York), as Corporate Trustee, (the “Corporate Trustee”) and Richard Tarnas (successor to Judith L. Bartolini, W. A. Spooner, Henry A. Theis, Oliver R. Brooks, Wesley L. Baker, Edwin F. McMichael and R. Amundsen), (the “Individual Trustee,” together with the Corporate Trustee, the “Trustees”). In connection with the issuance of the Securities, the Original Mortgage will be further supplemented by a Sixty-first Supplemental Indenture, to be dated as of July 2, 2014 (the “Supplemental Indenture” and the Original Mortgage as so supplemented, the “Mortgage”). To the extent there are no additional parties listed on Schedule I other than you, the term Representatives as used herein shall mean you as the Initial Purchasers, and the terms Representatives and Initial Purchasers shall mean either the singular or plural as the context requires. Certain terms used herein are defined in Section 21 hereof.

The sale of the Securities to the Initial Purchasers will be made without registration of the Securities under the Act in reliance upon exemptions from the registration requirements of the Act.

In connection with the sale of the Securities, the Company has prepared a preliminary offering memorandum, dated June 25, 2014 (as amended or supplemented at the date thereof, including any and all exhibits thereto, the “Preliminary Memorandum”), and a final offering memorandum, dated June 25, 2014 (as amended or supplemented at the date thereof, including any and all exhibits thereto, the “Final Memorandum”). Each of the Preliminary Memorandum and the Final Memorandum sets forth certain information concerning the Company and the Securities. The Company hereby confirms that it has authorized the use of the Disclosure Package, the Preliminary Memorandum and the Final Memorandum, and any amendment or supplement thereto, in connection with the offer and sale of the Securities by the Initial Purchasers.

1. Representations and Warranties. The Company represents and warrants to each of the Initial Purchasers as of the date of this Agreement that:

(a) The Company has been duly incorporated and is validly existing as a corporation in good standing under the laws of Kansas with full corporate power and authority to carry on the electric utility business in which it is engaged, and is duly qualified to do business as a foreign corporation and is in good standing under the laws of each jurisdiction which requires such qualification except where the failure to so qualify would not reasonably be expected to have a material adverse effect on the condition (financial or otherwise), earnings, business or properties of the Company, whether or not arising from transactions in the ordinary course of business, except as set forth in or contemplated in the Disclosure Package and the Final Memorandum (a “Material Adverse Effect”).

(b) The Company has corporate power and authority to execute and deliver, to take all actions required or permitted to be taken by the Company by or under, and to perform and observe the covenants and agreements on its part contained in, this Agreement, the Mortgage and the Securities.

(j) For so long as any of the Securities are outstanding and are “restricted securities” within the meaning of Rule 144(a)(3) under the Act, the Company, during any period in which it is not subject to and in compliance with Section 13 or 15(d) of the Exchange Act, will provide to each holder of such restricted securities and to each prospective purchaser (as designated by such holder) of such restricted securities, upon the request of such holder or prospective purchaser, any information required to be provided by Rule 144A(d)(4) under the Act. This covenant is intended to be for the benefit of the holders, and the prospective purchasers designated by such holders, from time to time of such restricted securities.

(n) The Company will not take, directly or indirectly, any action designed to, or that has constituted or that might reasonably be expected to, cause or result, under the Exchange Act or otherwise, in stabilization or manipulation of the price of any security of the Company to facilitate the sale or resale of the Securities.

(a) Subsequent to the Execution Time and prior to the Closing Date, there shall not have occurred any downgrading, nor shall any notice have been given of any intended or potential downgrading or of any review for a possible change that does not indicate the direction of the possible change, in the rating accorded the Company or any of the securities of the Company by any “nationally recognized statistical rating organization,” as such term is defined in Section 3(a)(62) of the Exchange Act.

(b) There shall not have been any Material Adverse Change since the date of the Disclosure Package, that, in the judgment of the Representatives, is material and adverse and that makes it, in the judgment of the Representatives, impracticable or inadvisable to market or deliver the Securities on the terms and in the manner contemplated in the Disclosure Package; and the Representatives shall have received, on the Closing Date, a certificate, dated the Closing Date and signed by either the chief executive officer or chief financial officer of the Company, to the foregoing effect.

The officer making such certificate may rely upon the best of his knowledge as to proceedings threatened.

11

(c) The Company shall have requested and caused Larry D. Irick, Vice President, General Counsel and Corporate Secretary for the Company (or any other lawyer of the Company reasonably satisfactory to the Representatives), to furnish to the Representatives his opinion, dated the Closing Date and addressed to the Representatives, to the effect that:

(i) the Company has been duly incorporated, is validly existing as a corporation in good standing under the laws of the State of Kansas 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 where the failure to so qualify would not have a Material Adverse Effect);

(ii) all of the issued shares of capital stock of the Company have been duly and validly authorized and issued, are fully paid and non-assessable, and (except as otherwise set forth in the Disclosure Package and the Final Memorandum) are owned directly by the Company’s parent, Westar Energy, Inc. (“Westar”), free and clear of all liens, encumbrances, equities or claims (such counsel being entitled to rely in respect of the opinion in this clause upon opinions of local counsel and in respect of matters of fact upon certificates of officers of Westar or the Company, provided that such counsel shall state that he believes that both the Initial Purchasers and he are justified in relying upon such opinions and certificates);

(iii) the Mortgage has been duly authorized, executed and delivered by the Company;

(iv) assuming the due authorization, execution and delivery by the other parties thereto, the Mortgage constitutes a valid and binding agreement of the Company, enforceable against the Company in accordance with its terms, subject to applicable bankruptcy, reorganization, insolvency and similar laws affecting creditors’ rights generally, concepts of reasonableness and equitable principles of general applicability;

(v) the Mortgage has been duly recorded and filed in each place in which such recording or filing is required to protect and preserve the lien of the Mortgage, and all taxes and recording or filing fees required to be paid in connection with the execution, recording or filing of the Mortgage have been duly paid;

(vi) the Company has good and sufficient title to, or a satisfactory easement in, all the real property, and has good and sufficient title to all the personal property described in the Mortgage as owned by it and subject to the lien of the Mortgage, except any which may have been released from the lien thereof pursuant to the provisions thereof, subject only to (a) minor leases and liens of judgments not prior to the lien of the Mortgage, which, in such counsel’s opinion, do not interfere with the Company’s business, (b) minor defects, irregularities and deficiencies in titles of properties and rights-of-way which, in such counsel’s opinion, do not materially impair the use of such property and rights-of-way for the purposes for which they are held by the Company, and (c) other permitted liens as defined in the Mortgage; subject to the qualifications set forth in this Section 6(a)(vi), the Mortgage constitutes a valid, direct first mortgage lien upon said properties and upon all franchises owned by the Company, which properties

12

and franchises include all the physical properties and franchises of the Company (other than classes of property expressly excepted in the Mortgage); all physical properties and franchises (other than classes of property expressly excepted in the Mortgage as aforesaid) thereafter acquired by the Company will, upon such acquisition, become subject to the lien thereof, subject, however, to liens permitted thereby and to any liens existing or placed upon such properties at the time of the acquisition thereof by the Company and except as described in the Disclosure Package and the Final Memorandum; and the descriptions of all such properties and assets contained in the granting clauses of the Mortgage are correct and adequate for the purposes of the Mortgage;

(vii) the Securities have been duly authorized, executed, and delivered by the Company;

13

jurisdiction of the United States of America or of any foreign jurisdiction is required for the performance by the Company of its obligations under this Agreement, the Mortgage or the Securities, provided that such counsel need not express an opinion as to federal or state securities or Blue Sky laws;

(xi) the Company possesses valid franchises, certificates of convenience and authority, licenses and permits authorizing it to carry on the electric utility business in which it is engaged, except in the cases that the failure to possess such franchises, certificates, licenses or permits, individually or in the aggregate, would not be reasonably expected to have a Material Adverse Effect, and the Company has not received any notice of proceedings relating to the revocation or modification of any such franchise, certificate of convenience and authority, license or permit which, singly or in the aggregate, if the subject of an unfavorable decision, ruling or finding, would reasonably be expected to have a Material Adverse Effect, except as set forth in or contemplated in the Disclosure Package and the Final Memorandum;

(xii) the statements under the caption “Description of the Bonds” in the Preliminary Memorandum and the Final Memorandum, insofar as such statements constitute a summary of the legal matters, documents or proceedings referred to therein, fairly present the information called for with respect to such legal matters, documents and proceedings;

(xiii) there is no pending or, to the knowledge of such counsel, threatened action, suit or proceeding by or before any court or governmental agency, authority or body or any arbitrator involving the Company or its property that is not adequately disclosed in the Disclosure Package and the Final Memorandum, except in each case for such proceedings that, if the subject of an unfavorable decision, ruling or finding would not singly or in the aggregate, have a Material Adverse Effect;

Such counsel shall also state that nothing has come to his attention that causes him to believe (1) that the Disclosure Package (except for the financial statements and other financial or statistical data derived therefrom that are included therein or omitted therefrom, as to which such counsel is not called upon to express any belief), at the Execution Time or as amended or supplemented, if applicable, as of the Closing Date, contained or contains an untrue statement of a material fact or omitted or omits to state a material fact necessary in order to make

14

the statements therein, in the light of the circumstances under which they were made, not misleading; or (2) that the Final Memorandum (except for the financial statements and other financial or statistical data derived therefrom that are included therein or omitted therefrom, as to which such counsel is not called upon to express any belief), as of its date or as amended or supplemented, if applicable, at the Closing Date, contained or contains an untrue statement of a material fact or omitted or omits to state a material fact necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading.

With respect to the preceding paragraph, such counsel may state that he has not been called upon to pass upon, and that he expresses no view regarding, the financial statements or financial schedules or statistical data derived therefrom or other accounting or financial data included in the Disclosure Package and the Final Memorandum, and that his opinion and belief is based upon his participation in the preparation of the Disclosure Package and the Final Memorandum (as amended or supplemented) and review and discussion of the contents thereof, but is without independent check or verification except as specified.

In expressing his opinion as to questions of the law of jurisdictions other than the State of Kansas and the United States, such counsel may rely to the extent reasonable on such counsel as may be reasonably acceptable to counsel to the Initial Purchasers. In addition, such counsel may reasonably rely as to questions of fact on certificates of responsible officers of the Company.

(d) The Representatives shall have received on the Closing Date an opinion of Davis Polk & Wardwell LLP, special counsel for the Company, dated the Closing Date, to the effect that:

(i) it is not necessary in connection with the offer, sale and delivery of the Securities to the Initial Purchasers under this Agreement or in connection with the initial resale of such Securities by the Initial Purchasers in the manner contemplated by this Agreement and the Final Memorandum to register the Securities under the Act, or to qualify the Mortgage under the Trust Indenture Act, it being understood that no opinion is expressed as to any subsequent offer or resale of any Security;

15

upon to express any opinion) that in such counsel’s experience is normally applicable to general business corporations in relation to transactions of the type contemplated by this Agreement, the Mortgage and the Securities, provided that such counsel need not express an opinion as to federal or state securities or Blue Sky laws;

(iv) no consent, approval, authorization, or order of, or qualification with, any governmental body or agency under the laws of the State of New York or any federal law of the United States of America (except with respect to consents, approvals and authorizations relating specifically to public utility companies or the utilities industry, as to which such counsel is not called upon to express any opinion) that in such counsel’s experience is normally applicable to general business corporations in relation to transactions of the type contemplated by this Agreement, the Mortgage and the Securities, is required for the execution, delivery and performance by the Company of its respective obligations under this Agreement, the Mortgage and the Securities, except such as may be required under federal or state securities or Blue Sky laws as to which such counsel need not express any opinion; and

(v) the statements included in the Final Memorandum under the caption “Certain U.S. Federal Income Tax Consequences,” insofar as they purport to describe provisions of U.S. federal income tax laws or legal conclusions with respect thereto, fairly and accurately summarize the matters referred to therein in all material respects.

In addition, such counsel shall state that nothing has come to the attention of such counsel that causes them to believe that, insofar as relevant to the offering of the Securities, (A) at the Execution Time, the Disclosure Package, contained an untrue statement of a material fact or omitted 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; or (B) the Final Memorandum as of its date or as amended or supplemented, if applicable, at the Closing Date, contained or contains any untrue statement of a material fact or omitted or omits 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.

With respect to the preceding paragraph, Davis Polk & Wardwell LLP may state that the primary purpose of its professional engagement is not to establish or confirm factual matters or financial, accounting or quantitative information and that they are not passing upon, and do not assume any responsibility for, the accuracy, completeness or fairness of the statements contained in the Disclosure Package or the Final Memorandum, and they have not themselves checked the accuracy, completeness or fairness of, or otherwise verified, the information furnished in such documents (except to the extent expressly set forth in their opinion letter), and that their opinion and belief is based upon their participation in the preparation of the Disclosure Package and the Final Memorandum and any amendments or supplements thereto and review and discussion of the contents thereof, but is without independent check or verification except as specified. Such counsel shall not be required to express a view as to the conveyance of the Disclosure Package or the information contained therein to investors.

16

(e) The Representatives shall have received on the Closing Date an opinion and negative assurances letter from Hunton & Williams LLP, counsel for the Initial Purchasers, each dated the Closing Date, covering the matters requested by and in form and substance reasonably satisfactory to the Representatives.

(f) The Representatives shall have received at the Execution Time a letter dated such date and on the Closing Date a letter dated such date, in each case in form and substance satisfactory to the Representatives, from Deloitte & Touche LLP, independent public accountants, containing statements and information of the type ordinarily included in accountants’ “comfort letters” with respect to the financial statements and certain financial information reviewed by them contained in or incorporated by reference in the Disclosure Package and the Final Memorandum and each other firm of independent accountants, if any, who audited or reviewed financial statements contained in or incorporated by reference in the Disclosure Package and the Final Memorandum, containing statements and information of the type ordinarily included in accountants’ “comfort letters” with respect to such financial statements and financial information.

(g) The Securities shall be eligible for clearance and settlement through The Depository Trust Company.

(h) The Representatives shall have received on the date hereof or on the Closing Date, as applicable, such additional documents as the Representatives shall have reasonably requested to confirm compliance with the conditions to closing listed herein.

If any of the conditions specified in this Section 6 shall not have been fulfilled when and as provided in this Agreement, or if any of the opinions and certificates mentioned above or elsewhere in this Agreement shall not be reasonably satisfactory in form and substance to the Representatives and counsel for the Initial Purchasers, this Agreement and all obligations of the Initial Purchasers hereunder may be cancelled at, or at any time prior to, the Closing Date by the Representatives. Notice of such cancellation shall be given to the Company in writing or by telephone or facsimile confirmed in writing.

7. Reimbursement of Expenses. If this Agreement shall be terminated by the Initial Purchasers 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 Initial Purchasers for all out-of-pocket expenses (including the fees and disbursements of their counsel) reasonably incurred by the Initial Purchasers in connection with this Agreement or the offering contemplated hereunder. This provision shall survive the termination or cancellation of this Agreement.

8. Indemnification and Contribution. (a) The Company agrees to indemnify and hold harmless each Initial Purchaser, the directors, officers, employees and agents of each Initial Purchaser and each person, if any, who controls each Initial Purchaser within the meaning of either Section 15 of the Act or Section 20 of the Exchange Act from and against any and all losses, claims, damages and liabilities arising out of, based upon or caused by any untrue statement or alleged untrue statement of a material fact contained in the Preliminary

17

Memorandum, the Disclosure Package (as amended or supplemented), any Issuer Written Information, the Final Memorandum (as amended or supplemented), or any other written information used by or on behalf of the Company in connection with the offer or sale of the Securities, or arising out of, based upon or caused by any omission or alleged omission to state therein a material fact necessary to make the statements therein not misleading, except insofar as such losses, claims, damages or liabilities arise out of, are based upon or are caused by any such untrue statement or omission or alleged untrue statement or omission based upon information furnished to the Company in writing by such Initial Purchaser through the Representatives expressly for use therein.

(b) Each Initial Purchaser severally, and not jointly, agrees to indemnify and hold harmless the Company, each of its directors, each of its officers, and each person who controls the Company within the meaning of either Section 15 of the Act or Section 20 of the Exchange Act, to the same extent as the foregoing indemnity from the Company to such Initial Purchaser, but only with reference to information relating to such Initial Purchaser furnished to the Company in writing by such Initial Purchaser through the Representatives expressly for use in the Preliminary Memorandum, the Disclosure Package (as amended or supplemented), any Issuer Written Information or the Final Memorandum (as amended or supplemented).

(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 either of the two preceding paragraphs, 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 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. In any such proceeding, any Indemnified Party shall have the right to retain its own counsel, but the fees and disbursements 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, upon advice of counsel the Indemnified Party concludes that counsel chosen by the Indemnifying Party to represent the Indemnified Party would be inappropriate due to actual or potential differing interests between the Indemnifying Party and the Indemnified 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. It is understood that the Indemnifying Party shall not, in connection with any proceeding or related proceedings in the same jurisdiction, be liable for the reasonable fees and disbursements of more than one separate firm (in addition to any local counsel) for all such Indemnified Parties and that all such fees and disbursements shall be reimbursed as they are incurred. In the case of any such separate firm for the Initial Purchasers and such control person of the Initial Purchasers, such firm shall be designated in writing by the Representatives. In the case of any such separate firm for the Company and such directors, officers and controlling person of the Company, such firm shall be designated in writing by the Company. 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, to the extent provided for in the two immediately

18

preceding paragraphs, 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 (x) includes an unconditional release of such Indemnified Party from all liability on claims that are the subject matter of such 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) If the indemnification provided for in the first or second paragraph this Section 8 is unavailable to or insufficient to hold harmless an Indemnified Party in respect of any losses, claims, damages or liabilities for which indemnification is provided herein, then the Indemnifying Party, in lieu of indemnifying such Indemnified Party, shall contribute to the amount paid or payable by such Indemnified Party as a result of such losses, claims, damages or liabilities (i) in such proportion as is appropriate to reflect the relative benefits received by the Company on the one hand and the Initial Purchasers on the other from the offering of the Securities or (ii) if the allocation provided by clause (i) above is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to in clause (i) above but also the relative fault of the Company on the one hand and of the Initial Purchasers on the other in connection with the statements or omissions which resulted in such losses, claims, damages or liabilities, as well as any other relevant equitable considerations. The relative benefits received by the Company and the Initial Purchasers shall be deemed to be in the same proportion as the net proceeds to the Company from the offering of the Securities (before deducting expenses) bears to the total underwriting discounts and commissions received by the Initial Purchasers in respect thereof, in each case as set forth in the table on the cover page of the Final Memorandum. The relative fault of the Company and the Initial Purchasers 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 on the one hand or by the Initial Purchasers on the other and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission.

(e) The Company and the Initial Purchasers agree that it would not be just and equitable if contribution pursuant to this Section 8 were determined by pro rata allocation (even if the Initial Purchasers were treated as one entity for such purpose) or by any other method of allocation which does not take account of the equitable considerations referred to in paragraph (d) above. 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. For purposes of this Section 8, each person who controls an Initial Purchaser within the meaning of either the Act or the Exchange Act and each director, officer, employee and agent of an Initial Purchaser shall have the same rights to contribution as such Initial Purchaser, and each person who controls the Company within the meaning of either the Act or the Exchange Act, and each officer and 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 and the preceding paragraph. Notwithstanding the provisions of this Section 8, in no

19

case shall any Initial Purchaser be responsible for any amount in excess of the amount by which the total price at which Securities sold by such Initial Purchaser exceeds the amount of any damages which such Initial Purchaser has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission. Notwithstanding the provisions of this paragraph (e), 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.

9. Default by an Initial Purchaser. If any one or more Initial Purchasers shall fail to purchase and pay for any of the Securities agreed to be purchased by such Initial Purchaser hereunder and such failure to purchase shall constitute a default in the performance of its or their obligations under this Agreement, and the aggregate amount of the Securities which such defaulting Initial Purchaser or Purchasers agreed but failed or refused to purchase is not more than one-tenth of the aggregate amount of the Securities to be purchased on such date, the remaining Initial Purchasers shall be obligated severally to take up and pay for (in the respective proportions which the principal amount of Securities set forth opposite their names in Schedule I hereto bears to the aggregate principal amount of Securities set forth opposite the names of all the remaining Initial Purchasers) the Securities which the defaulting Initial Purchaser or Initial Purchasers agreed but failed or refused to purchase; provided that in no event shall the amount of Securities that any Initial Purchaser has agreed to purchase pursuant to this Agreement be increased pursuant to this Section 9 by an amount in excess of one-ninth of such amount of Securities without the written consent of such Initial Purchaser. If on the Closing Date any Initial Purchaser or Initial Purchasers shall fail or refuse to purchase Securities and the aggregate amount of Securities with respect to which such default occurs is more than one-tenth of the aggregate amount of Securities to be purchased on such date, and arrangements satisfactory to the Representatives and the Company for the purchase of such Securities are not made within 36 hours after such default, this Agreement shall terminate without liability on the part of any non-defaulting Initial Purchaser or the Company. In the event of a default by any Initial Purchaser as set forth in this Section 9, the Closing Date shall be postponed for such period, not exceeding five Business Days, as the Representatives shall determine in order that the required changes in the Final Memorandum or in any other documents or arrangements may be effected. Nothing contained in this Agreement shall relieve any defaulting Initial Purchaser of its liability, if any, to the Company or any nondefaulting Initial Purchaser for damages occasioned by its default hereunder.

10. Termination. This Agreement shall be subject to termination in the absolute discretion of the Representatives, by notice given by the Representatives to the Company, if (a) after the Execution Time and prior to the Closing Date (i) trading generally shall have been suspended or materially limited on or by, as the case may be, the New York Stock Exchange, the American Stock Exchange or the Financial Industry Regulatory Authority, Inc., (ii) a general moratorium on commercial banking activities in New York shall have been declared by either Federal or New York State authorities, or (iii) there shall have occurred any outbreak or escalation of hostilities, declaration by the United States of a national emergency or war, or any change in financial markets or any calamity or crisis that, in the judgment of the Representatives, is material and adverse and (b) in the case of any of the events specified in clauses (a)(i) through (iii), such event, singly or together with any other such event, makes it, in the judgment of the Representatives, impracticable or inadvisable to market or deliver the Securities on the terms and in the manner contemplated in the Disclosure Package and the Final Memorandum (exclusive of any amendment or supplement thereto) and this Agreement.

20

11. Representations and Indemnities to Survive. The respective agreements, representations, warranties, indemnities and other statements of the Company or its officers and of the Initial Purchasers 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 the Initial Purchasers or the Company or any of the indemnified 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.
