 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, $300,000,000 principal amount of its 6.70% First Mortgage Bonds
due 2019 (the “Securities”). The Securities are to be issued under a Mortgage and Deed of Trust, dated as of April 1, 1940 (as amended and supplemented, the “Original Mortgage”), between the Company and The
Bank of New York Mellon Trust Company, N.A., as successor to Guaranty Trust Company of New York, and Judith L. Bartolini, as successor to Henry A. Theis, as trustees (the “Trustee”). In connection with the issuance of the
Securities, the Original Mortgage will be further supplemented by a Fifth-Fourth Supplemental Indenture, to be dated as of June 11, 2009 (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 8, 2009 (as amended or supplemented at the date thereof, including any and all exhibits thereto, the “Preliminary Memorandum”), and a final offering
memorandum, dated June 8, 2009 (as amended or supplemented at the Execution Time, 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, and agrees with, each Initial Purchaser as set forth below in this Section 1. 
 (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 Official Statement (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. 
 (c) This Agreement has been duly authorized, executed and delivered by the Company; the Mortgage and the Securities have been duly authorized by the Company and the Mortgage (excluding the Supplemental Indenture) has
been duly executed and delivered by the Company; and the Mortgage (excluding the Supplemental Indenture) constitutes a legal, valid, binding instrument enforceable against the Company in accordance with its terms (subject, as to the enforcement of
remedies, to applicable bankruptcy, reorganization, insolvency, moratorium or other laws affecting creditors’ rights generally from time to time in effect and to general principles of equity); at the Closing Date (as defined below), the
Mortgage (including the Supplemental Indenture) will constitute the valid and legally binding obligation of the Company, enforceable in accordance with its terms, subject to the limitations described above; and the Securities, when executed and
authenticated in accordance with the provisions of the Mortgage and delivered to and paid for by the Initial Purchasers, will have been duly executed and delivered by the Company and will constitute the legal, valid and binding obligations of the
Company entitled to the benefits of the Mortgage (subject, as to the enforcement of remedies, to applicable bankruptcy, reorganization, insolvency, moratorium or other laws affecting creditors’ rights generally from time to time in effect and
to general principles of equity).

encumbrance upon any property or assets of the Company pursuant to, (i) the articles of incorporation or by-laws of the Company; (ii) the terms of any indenture, contract, lease, mortgage, deed of trust, note agreement, loan agreement or
other agreement, obligation, condition, covenant or instrument to which the Company is a party or bound or to which its property is subject; or (iii) any statute, law, rule, regulation, judgment, order or decree applicable to the Company of any

property is pending or, to the best knowledge of the Company, threatened that (i) could reasonably be expected to have a Material Adverse Effect on the performance of this Agreement, the Indenture or the consummation of any of the transactions
contemplated hereby or thereby or (ii) could reasonably be expected to have a Material Adverse Effect on the Company, except as set forth in or contemplated in the Disclosure Package and the Final Memorandum (exclusive of any amendment or
supplement thereto).

Company or any of its properties, as applicable, except, in the cases of clauses (ii) and (iii), for violations or defaults which would not reasonably be expected to have a Material Adverse Effect.

the Securities for sale by the Initial Purchasers under the laws of such jurisdictions as the Representatives may designate and will maintain such qualifications in effect so long as required for the sale of the Securities; 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

otherwise) by the Company or any Affiliate of the Company or any person in privity with the Company or any Affiliate of the Company), directly or indirectly, or announce the offering, of any debt securities issued or guaranteed by the Company (other

the provisions hereof, to the performance by the Company of its obligations hereunder and to the following additional conditions: 
 (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

436(g)(2) under the Act. 
 (b) There shall not have been any Material Adverse Change from that set forth in the Disclosure Package, that, in

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. Such certificate
will also provide that the representations and warranties of the Company contained herein are true and correct as of the Closing Date and that the Company has complied with all agreements and satisfied all conditions on its part to be performed or
satisfied hereunder at or prior to the Closing Date. The officer making such certificate may rely upon the best of his knowledge as to proceedings threatened. 
  

 10 








 (c) The Company shall have requested and caused Larry D. Irick, Secretary for the Company, 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, 

  

 11 








 
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 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; 
 (viii) when the Securities have been duly executed and authenticated in accordance with the
provisions of the Mortgage, the Securities will be valid and binding obligations of the Company, enforceable against them in accordance with their terms, subject to applicable bankruptcy, reorganization, insolvency and similar laws affecting
creditors’ rights generally, concepts of reasonableness and equitable principles of general applicability, and will be entitled to the benefits of the Mortgage and to the lien of the Mortgage; 
 (ix) the Agreement has been duly authorized, executed and delivered by the Company; 
 (x) except as rights to indemnity and contribution under this Agreement may be limited under applicable law, the execution and delivery by
the Company of, and the performance by the Company of its obligations under this Agreement, the Mortgage and the Securities will not contravene any provision of the laws of the State of Kansas or any federal law of the United States of America
(including laws relating specifically to electric utility companies and the electric utility industry) that in such counsel’s experience is normally applicable to general business corporations in relation to transactions of the topic
contemplated by this Agreement, or, to the best knowledge of such counsel, of any other state or jurisdiction of the United States, or the articles of incorporation or by-laws (or similar organizational document) of the Company or, to the best
knowledge of such counsel, any material agreement or other material instrument binding upon the 

  

 12 








 
Company, the Mortgage or the Securities, provided that such counsel need not express an opinion as to federal or state securities or Blue Sky laws, and no
consent, approval or authorization of any governmental body or agency under the laws of the State of Kansas or any federal law of the United States of America (except with respect to consents, approvals and authorizations relating specifically to
the 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 topic contemplated by the Agreement, or, to the best knowledge of such counsel, of any other state or jurisdiction of the United States of America or of any foreign jurisdiction is required for the performance by the Company of its obligations
under the 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; 
 (xiv) the
Company has complied with K.S.A. 9 66- 125 with respect to the issuance of the Securities. No additional consent, approval, authorization, filing with or order of (a) FERC under the Federal Power Act, (b) the KCC or (c) to the

knowledge of the Company, any court or governmental agency or body is required in connection with the transactions contemplated herein, except such as may be
required under the blue sky laws of any jurisdiction in connection with the purchase and distribution of the Securities by the Initial Purchasers in the manner contemplated in the Agreement and in the Preliminary Memorandum and the Final Memorandum.

 Such counsel shall also confirm he has no reason to believe that the Disclosure Package, as amended or supplemented at the Execution Time,
contained any untrue statement of a material fact or omitted 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 (in each case, other than the
financial statements and other financial information contained therein, as to which such counsel need express no opinion); and such counsel has no reason to believe that the Final Memorandum, as of its date or on the Closing Date, contained or
contains any untrue statement of a material fact or omitted or omits to state any material fact necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading (in each case, other than the
financial statements and other financial information contained therein, as to which such counsel need express no opinion). 
 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 Company shall have requested and caused Davis
Polk & Wardwell, special counsel for the Company, to furnish the Representatives an opinion, dated the Closing Date and addressed to the Representatives, 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 the Agreement or
in connection with the initial resale of such Securities by the Initial Purchasers in the manner contemplated by the Agreement and the Final Memorandum to register the Securities under the Securities Act of 1933, as amended, or to qualify the
Mortgage under the Trust Indenture Act of 1939, as amended, it being understood that no opinion is expressed as to any subsequent offer or resale of any Security; 
  

 14 








 (ii) the Company is not, and after giving effect to the offering and sale of the
Securities and the application of the proceeds thereof as described in the Disclosure Package and the Final Memorandum will not be, required to register as an “investment company” as such term is defined in the Investment Company Act;

 (iii) the execution and delivery by the Company of, and the performance by the Company of its obligations under, the
Mortgage and the Securities, will not contravene any provision of the laws of the State of New York or any federal law of the United States of America (except with respect to laws 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 the Mortgage and the
Securities, provided that such counsel need not express an opinion as to federal or state securities laws; 
 (iv) no consent,
approval or 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 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
as may be required under federal or state securities or Blue Sky laws as to which such counsel need not express any opinion; 
 (v) the statements included in the Final Memorandum under the caption “Certain U.S. Federal Income Tax Consequences for Non-U.S. Holders,” 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; 
 Such counsel
shall also confirm such counsel has no reason to believe that the Disclosure Package, as amended or supplemented at the Execution Time, contained any untrue statement of a material fact or omitted 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 (in each case, other than the financial statements and other financial information contained therein, as to which such counsel need express no


  

 15 








 
opinion); and such counsel has no reason to believe that the Final Memorandum, as of its date or on the Closing Date, contained or contains any untrue
statement of a material fact or omitted or omits to state any material fact necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading (in each case, other than the financial statements and
other financial information contained therein, as to which such counsel need express no opinion). 
 With respect to the preceding paragraph,
Davis Polk & Wardwell may state that they have not been called upon to pass upon, and that they express 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 or the Final Memorandum 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. 
 (e) The Representatives shall have received from Dewey & LeBoeuf LLP, counsel for the Initial
Purchasers, such opinion or opinions, dated the Closing Date and addressed to the Representatives, with respect to the issuance and sale of the Securities, the Mortgage, the Disclosure Package, the Final Memorandum (as amended or supplemented at the
Closing Date) and other related matters as the Representatives may reasonably require, and the Company shall have furnished to such counsel such documents as they request for the purpose of enabling them to pass upon such matters. 
 (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) Prior to the Closing Date, the Company shall have furnished to the Representatives
such further information, certificates and documents as the Representatives may reasonably request. 
  

 16 








 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 Memorandum, the Final Memorandum, any Issuer Written Information or any other written information used by or on behalf of the Company in connection with the offer or sale of the Securities, or in any amendment or
supplement thereto, or arising out of, based upon 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 loss,
claim, damage or liability arises out of, is based upon or is caused by any such untrue statement or omission or alleged untrue statement or omission based upon information furnished in writing by such Initial Purchaser through the Representatives
expressly for use therein; provided, further, that the foregoing indemnity agreement with respect to the Preliminary Memorandum shall not inure to the benefit of any Initial Purchaser from whom the person asserting any such losses,
claims, damages or liabilities purchased Securities, or any person controlling such Initial Purchaser where it shall have been determined by a court of competent jurisdiction by final and nonappealable judgment that (i) prior to the Execution
Time the Company shall have notified such Initial Purchaser that the Preliminary Memorandum contains an untrue statement of material fact or omits to state therein a material fact required to be stated therein in order to make the statements therein
not misleading, (ii) such untrue statement or omission of a material fact was corrected and such corrected Preliminary Memorandum or Issuer Written Information was provided to such Initial Purchaser far enough in advance of the Execution Time
so that such corrected Preliminary Memorandum or Issuer Written Information could have been conveyed to such person prior to the Execution Time, (iii) such corrected Preliminary Memorandum or Issuer Written Information was not conveyed to such
person at or prior to the 

  

 17 








 
Execution Time, and (iv) such loss, claim, damage or liability would not have occurred had the corrected Preliminary Memorandum or Issuer Written
Information been conveyed to such person as provided for in clause (iii) above. This indemnity agreement will be in addition to any liability that the Company may otherwise have. 
 (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 the Act or the Exchange Act, to the same extent as the foregoing indemnity to each Initial Purchaser, but only with reference to written information relating to such Initial
Purchaser furnished to the Company by such Initial Purchaser through the Representatives expressly for use in the Preliminary Memorandum or the Final Memorandum or any Issuer Written Information (or in any amendment or supplement thereto).

 (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 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 

  

 18 








 
been sought hereunder by such Indemnified Party unless such settlement includes an unconditional release of such Indemnified Party from all liability on
claims that are the subject matter of such proceeding. 
 (d) If the indemnification provided for in 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 respective proportions as the net proceeds from the offering (before deducting expenses)
received by the Company bear to the total discounts and commissions received by the Initial Purchasers in respect thereof. 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 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 

  

 19 








 
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, 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 to purchase; provided, however, that in the event that the aggregate principal amount of Securities which the defaulting Initial Purchaser or Initial Purchasers agreed but failed to purchase shall
exceed 10% of the aggregate principal amount of Securities set forth in Schedule I hereto, the remaining Initial Purchasers shall have the right to purchase all, but shall not be under any obligation to purchase any, of the Securities, and if such
nondefaulting Initial Purchasers do not purchase all the Securities, this Agreement will terminate without liability to any nondefaulting 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 NYSE Amex
Equities 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. 
 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 

  

 20 








 
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. 
 12. Notices. All communications hereunder will be in writing and effective only on receipt, and, if sent to the Representatives, will be mailed,
delivered or telefaxed to BNY (fax no.: (212)-635-8059) and confirmed to BNY at One Wall Street, 18th Floor, New York, New York 10286, Attention: Dan Klinger; the Citi General Counsel (fax no.: (212) 816-7912) and confirmed to Citi at 388

mailed, delivered or telefaxed to (785)-575-8136 and confirmed to it at 818 South Kansas Avenue, Topeka, KS 66612, attention of the Legal Department. 
 13. 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. 
 14. Applicable Law. This Agreement will be governed by and construed in accordance with the internal laws of the State of New York. 
 15. Headings. The section headings used herein are for convenience only and shall not affect the construction hereof. 
 16. Successors. This Agreement will inure to the benefit of and be binding upon the parties hereto and their respective successors and the
indemnified persons referred to in Section 8 hereof and their respective successors, and no other person will have any right or obligation hereunder. 
 17. Waiver of Jury Trial. Each of the parties hereto hereby irrevocably waives its rights to jury trial of any claim or cause of action based upon or arising out of or relating to this Agreement or the
transactions contemplated hereby. 
 18. Internet Document Service. The Company hereby agrees that Citi may provide copies of the
Preliminary Memorandum and Final Memorandum and any other agreement or document relating to the offer and sale of the Securities, including, without limitation, the Mortgage, to Xtract Research LLC (“Xtract”) following the Closing
Date for inclusion in an online research service sponsored by Xtract, access to which is restricted to “qualified institutional buyers” (as defined in Rule 144A under the Act). 
 19. Integration. This Agreement supersedes all prior agreements and understandings (whether written or oral) between the Company and the Initial
Purchasers, or any of them, with respect to the subject matter hereof. 
  

 21 








 20. No Fiduciary Duty. The Company acknowledges and agrees that the Initial Purchasers are acting
solely in the capacity of an arm’s length contractual counterparty to the Company with respect to the offering of Securities contemplated hereby (including in connection with determining the terms of the offering) and not as a financial advisor
or a fiduciary to, or an agent of, the Company or any other person and will not claim that the Initial Purchasers are acting in such capacity in connection with the offering of the Securities contemplated hereby. Additionally, none of the Initial
Purchasers is advising the Company or any other person as to any legal, tax, investment, accounting or regulatory matters in any jurisdiction with respect to the offering of Securities contemplated hereby. The Company shall consult with its own
advisors concerning such matters and shall be responsible for making its own independent investigation and appraisal of the transactions contemplated hereby, and the Initial Purchasers shall have no responsibility or liability to the Company with
respect thereto. Any review by the Initial Purchasers of the Company, the transactions contemplated hereby or other matters relating to such transactions will be performed solely for the benefit of the Initial Purchasers and shall not be on behalf
of the Company.
