 As Representatives of the

 Ladies and Gentlemen: 
 CACI International Inc, a Delaware corporation (the “Company”), proposes to issue and sell to the
several initial purchasers listed in Schedule 1 hereto (the “Initial Purchasers”), for whom you are acting as Representatives (the “Representatives”), $270,000,000 aggregate principal amount of its 2.125% Convertible Senior
Subordinated Notes Due 2014 (the “Firm Securities”). The Securities (as defined below) will be issued pursuant to an Indenture to be dated as of May 16, 2007, (the “Indenture”) between the Company and The Bank of New York,
as trustee (the “Trustee”). The Company also proposes to issue and sell to the Initial Purchasers not more than an additional $30,000,000 aggregate principal amount of its 2.125% Convertible Senior Subordinated Notes Due 2014 (the
“Additional Securities”) if and to the extent that the Initial Purchasers shall have exercised the right to purchase such 2.125% Convertible Senior Subordinated Notes Due 2014 granted to the Initial Purchasers in Section 1 hereof. The
Firm Securities and the Additional Securities are hereinafter collectively referred to as the “Securities”. The Securities will be convertible into cash and shares of common stock of the Company, par value $0.10 per share (the “Common
Stock”), and, upon the issuance of such shares of Common Stock upon such conversion, the holders of such shares of Common Stock will receive rights (the “Rights”) associated with such Common Stock to the extent provided for 

 
in the Rights Agreement dated as of July 11, 2003 between the Company and American Stock Transfer & Trust Company, as Rights Agent (the
“Rights Agreement”), but only to the extent that such Rights Agreement remains in effect at the time of issuance. The shares of Common Stock and accompanying Rights that may be issuable upon conversion of the Securities are referred to
herein as the “Underlying Securities.” 
 The Securities will be sold to the Initial Purchasers without being registered under the
Securities Act of 1933, as amended (the “Securities Act”), in reliance upon an exemption therefrom. The Company has prepared a preliminary offering memorandum dated May 9, 2007 (the “Preliminary Offering Memorandum”) and
will prepare an offering memorandum dated the date hereof (the “Offering Memorandum”) setting forth information concerning the Company and the Securities. Copies of the Preliminary Offering Memorandum have been, and copies of the Offering
Memorandum will be, delivered by the Company to the Initial Purchasers pursuant to the terms of this Agreement. The Company hereby confirms that it has authorized the use of the Preliminary Offering Memorandum, the other Time of Sale Information (as
defined below) and the Offering Memorandum in connection with the offering and resale of the Securities by the Initial Purchasers in the manner contemplated by this Agreement. References herein to the Preliminary Offering Memorandum, the Time of
Sale Information and the Offering Memorandum shall be deemed to refer to and include any document incorporated by reference therein. 
 At or
prior to the time when sales of the Securities are first made (the “Time of Sale”), the following information shall have been prepared (collectively with the pricing information set forth on Annex A hereto, the “Time of Sale
Information”): the Preliminary Offering Memorandum, as supplemented and amended by the written communications listed on Annex A hereto. 
 Holders of the Securities (including the Initial Purchasers and their direct and indirect transferees) will be entitled to the benefits of a Registration Rights Agreement, to be dated the Closing Date (as defined below) and in a form
mutually acceptable to the Company and the Initial Purchasers (the “Registration Rights Agreement”), pursuant to which the Company will agree to file one or more registration statements with the Securities and Exchange Commission (the
“Commission”) providing for the registration under the Securities Act of the Securities or the shares of Common Stock that are issuable upon conversion of the Securities or that have been issued upon any conversion of the Securities.

 The Company hereby confirms its agreement with the several Initial Purchasers concerning the purchase and resale of the Securities, as
follows:

Additional Securities at the Purchase Price plus accrued interest, if any, from the Closing Date (as defined below) to the date of payment and delivery. If you, on behalf of the Initial Purchasers, exercise such option, you shall so notify the
Company in writing not later than 30 days after the date of this Agreement, which notice shall specify the principal amount of Additional Securities to be purchased by the Initial Purchasers and the date on which such Additional Securities are to be
purchased. Such date may be the same as the Closing Date but not earlier than the Closing Date nor later than ten business days after the date of such notice. 
 (b) The Company understands that the Initial Purchasers intend to offer the Securities for resale on the terms set forth in the Time of
Sale Information. Each Initial Purchaser, severally and not jointly, represents, warrants and agrees that:

taken or will take reasonable steps to ensure that the purchaser of the Securities is aware that such sale is being made in reliance on Rule 144A. 
 (c) Each Initial Purchaser acknowledges and agrees that the Company and, for purposes of the opinions to be delivered to the Initial Purchasers pursuant to Sections 6(g) and 6(h), counsel for the Company and counsel
for the Initial Purchasers, respectively, may rely upon the accuracy of the representations and warranties of the Initial Purchasers, and compliance by the Initial Purchasers with their agreements, contained in paragraph (b) above, and each
Initial Purchaser hereby consents to such reliance. 
 (d) The Company acknowledges and agrees that the Initial Purchasers may
offer and sell Securities through any affiliate of an Initial Purchaser and that any such affiliate may offer and sell Securities purchased by it to or through any Initial Purchaser, so long as the affiliate only offers and sells the Securities to
persons it reasonably believes to be QIBs in transactions pursuant to Rule 144A and in connection with each such sale, it has taken or will take reasonable steps to ensure that the purchaser of the Securities is aware that such sale is being made in
reliance on Rule 144A.

agreements and understandings (whether written or oral) between the Company and the several Initial Purchasers, or any of them, with respect to the subject matter hereof. The Company hereby waives and releases, to the fullest extent permitted by
law, any claims that the Company may have against the several Initial Purchasers with respect to any breach or alleged breach of agency or fiduciary duty.

demand shall be brought or asserted against any person in respect of which indemnification may be sought pursuant to either paragraph (a) or (b) above, such person (the “Indemnified Person”) shall promptly notify the person
against whom such indemnification may be sought (the “Indemnifying Person”) in writing; provided that the failure to notify the Indemnifying Person shall not relieve it from any liability that it may have under this Section 7
except to the extent that it has been materially prejudiced (through the forfeiture of substantive rights or defenses) by such failure; and provided, further, that the failure to notify the Indemnifying Person shall not relieve it from
any liability that it may have to an Indemnified Person otherwise than under this Section 7. If any such proceeding shall be brought or asserted against an Indemnified Person and it shall have notified the Indemnifying Person thereof, the
Indemnifying Person shall retain counsel reasonably satisfactory to the Indemnified Person (who shall not, without the consent of the Indemnified Person, be counsel to the Indemnifying Person in such proceeding) to represent the Indemnified Person
and any others entitled to indemnification pursuant to this Section 7 that the Indemnifying Person 

  

 23 

 
may designate in such proceeding and shall pay the fees and expenses of such proceeding and shall pay the fees and expenses of such counsel related to such
proceeding, as incurred. In any such proceeding, any Indemnified Person 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 Person unless (i) the Indemnifying
Person and the Indemnified Person shall have mutually agreed to the contrary in writing; (ii) the Indemnifying Person shall have failed within a reasonable time to retain counsel reasonably satisfactory to the Indemnified Person; (iii) the
Indemnified Person shall have reasonably concluded that there may be legal defenses available to it that are different from or in addition to those available to the Indemnifying Person; or (iv) the named parties in any such proceeding
(including any impleaded parties) include both the Indemnifying Person and the Indemnified Person and representation of both parties by the same counsel would be inappropriate due to actual or potential differing interests between them. It is
understood and agreed that the Indemnifying Person shall not, in connection with any proceeding or related proceeding in the same jurisdiction, be liable for the reasonable fees and expenses of more than one separate firm (in addition to any local
counsel) for all Indemnified Persons, and that all such reasonable fees and expenses shall be reimbursed as they are incurred. Any such separate firm for any Initial Purchaser, its affiliates, directors and officers and any control persons of such
Initial Purchaser shall be designated in writing by J.P. Morgan Securities Inc. and Banc of America Securities LLC and any such separate firm for the Company, its directors and officers and any control persons of the Company shall be designated in
writing by the Company. The Indemnifying Person 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
Person agrees to indemnify each Indemnified Person to the extent set forth in Section 7(a) or 7(b), as the case may be, from and against any loss or liability by reason of such settlement or judgment. Notwithstanding the foregoing sentence, if
at any time an Indemnified Person shall have requested that an Indemnifying Person reimburse the Indemnified Person for reasonable fees and expenses of counsel as contemplated by this paragraph, the Indemnifying Person shall be liable for any
settlement of any proceeding effected without its prior written consent if (i) such settlement is entered into more than 60 days after receipt by the Indemnifying Person of such request and more than 30 days after notice of such settlement is
received by the Indemnifying Person and (ii) the Indemnifying Person shall not have reimbursed the Indemnified Person to the extent required by this Section 7 prior to the date of such settlement. No Indemnifying Person shall, without the
written consent of the Indemnified Person, effect any settlement of any pending or threatened proceeding in respect of which any Indemnified Person is or could have been a party and indemnification could have been sought hereunder by such
Indemnified Person, unless such settlement (x) includes an unconditional release of such Indemnified Person, in form and substance reasonably satisfactory to such Indemnified Person, from all liability on claims that are the subject matter of
such proceeding and (y) does not include any statement as to or any admission of fault, culpability or a failure to act by or on behalf of such Indemnified Person. 
 (d) Contribution. If the indemnification provided for in paragraphs (a) and (b) above is unavailable to an Indemnified
Person or insufficient in respect of any losses, claims, damages or liabilities referred to therein, then each Indemnifying Person under 

  

 24 

 
such paragraph, in lieu of indemnifying such Indemnified Person thereunder, shall contribute to the amount paid or payable by such Indemnified Person 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) is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to in clause (i) but also the relative fault of the Company
on the one hand and the Initial Purchasers on the other 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 Initial Purchasers on the other shall be deemed to be in the same respective proportions as the net proceeds (before deducting expenses) received by the Company from the sale of the Securities and the
total discounts and commissions received by the Initial Purchasers in connection therewith, as provided in this Agreement, bear to the aggregate offering price of the Securities. The relative fault of the Company on the one hand and the Initial
Purchasers on the other 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 Initial Purchasers and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. 
 (e) Limitation on Liability. The Company and the Initial Purchasers agree that it would not be just and equitable if contribution
pursuant to this Section 7 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 that does not take account of the equitable
considerations referred to in paragraph (d) above. The amount paid or payable by an Indemnified Person as a result of the losses, claims, damages and liabilities referred to in paragraph (d) above shall be deemed to include, subject to the
limitations set forth above, any reasonable legal or other expenses incurred by such Indemnified Person in connection with any such action or claim. Notwithstanding the provisions of this Section 7, in no event shall an Initial Purchaser be
required to contribute any amount in excess of the amount by which the total discounts and commissions received by such Initial Purchaser with respect to the offering of the Securities exceeds the amount of any damages that such Initial Purchaser
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 Initial Purchasers’ obligations to contribute pursuant to this Section 7 are several in proportion to their respective purchase
obligations hereunder and not joint. 
 (f) Non-Exclusive Remedies. The remedies provided for in this Section 7
are not exclusive and shall not limit any rights or remedies that may otherwise be available to any Indemnified Person at law or in equity. 
  

 25 

 8. Termination. This Agreement may be terminated in the absolute discretion of the
Representatives, by notice to the Company, if after the execution and delivery of this Agreement and on or prior to the Closing Date (i) trading generally shall have been suspended or materially limited on the New York Stock Exchange or the
over-the-counter market; (ii) trading of any securities issued or guaranteed by the Company shall have been suspended on any exchange or in any over-the-counter market; (iii) a general moratorium on commercial banking activities shall have
been declared by federal or New York State authorities; or (iv) there shall have occurred any outbreak or escalation of hostilities or any change in financial markets or any calamity or crisis, either within or outside the United States, that,
in the judgment of the Representatives, is material and adverse and makes it impracticable or inadvisable to proceed with the offering, sale or delivery of the Securities on the terms and in the manner contemplated by this Agreement, the Time of
Sale Information and the Offering Memorandum. 
 9. Defaulting Initial Purchaser. 
 (a) If, on the Closing Date, any Initial Purchaser defaults on its obligation to purchase the Securities that it has agreed to purchase
hereunder, the non-defaulting Initial Purchasers may in their discretion arrange for the purchase of such Securities by other persons satisfactory to the Company on the terms contained in this Agreement. If, within 36 hours after any such default by
any Initial Purchaser, the non-defaulting Initial Purchasers do not arrange for the purchase of such Securities, then the Company shall be entitled to a further period of 36 hours within which to procure other persons satisfactory to the
non-defaulting Initial Purchasers to purchase such Securities on such terms. If other persons become obligated or agree to purchase the Securities of a defaulting Initial Purchaser, either the non-defaulting Initial Purchasers or the Company may
postpone the Closing Date for up to five full business days in order to effect any changes that in the opinion of counsel for the Company or counsel for the Initial Purchasers may be necessary in the Time of Sale Information, the Offering Memorandum
or in any other document or arrangement, and the Company agrees to promptly prepare any amendment or supplement to the Time of Sale Information or the Offering Memorandum that effects any such changes. As used in this Agreement, the term
“Initial Purchaser” includes, for all purposes of this Agreement unless the context otherwise requires, any person not listed in Schedule 1 hereto that, pursuant to this Section 9, purchases Securities that a defaulting Initial
Purchaser agreed but failed to purchase. 
 (b) If, after giving effect to any arrangements for the purchase of the Securities
of a defaulting Initial Purchaser or Initial Purchasers by the non-defaulting Initial Purchasers and the Company as provided in paragraph (a) above, the aggregate principal amount of such Securities that remains unpurchased does not exceed
one-eleventh of the aggregate principal amount of all the Securities, then the Company shall have the right to require each non-defaulting Initial Purchaser to purchase the principal amount of Securities that such Initial Purchaser agreed to
purchase hereunder plus such Initial Purchaser’s pro rata share (based on the principal amount of Securities that such Initial Purchaser agreed to purchase hereunder) of the Securities of such defaulting Initial Purchaser or
Initial Purchasers for which such arrangements have not been made. 
  

 26 

 (c) If, after giving effect to any arrangements for the purchase of the Securities of a
defaulting Initial Purchaser or Initial Purchasers by the non-defaulting Initial Purchasers and the Company as provided in paragraph (a) above, the aggregate principal amount of such Securities that remains unpurchased exceeds one-eleventh of
the aggregate principal amount of all the Securities, or if the Company shall not exercise the right described in paragraph (b) above, then this Agreement shall terminate without liability on the part of the non-defaulting Initial Purchasers.
Any termination of this Agreement pursuant to this Section 9 shall be without liability on the part of the Company, except that the Company will continue to be liable for the payment of expenses as set forth in Section 10 hereof and except
that the provisions of Section 7 hereof shall not terminate and shall remain in effect. 
 (d) Nothing contained herein
shall relieve a defaulting Initial Purchaser of any liability it may have to the Company or any non-defaulting Initial Purchaser for damages caused by its default. 
 10. Payment of Expenses. 
 (a) Whether or not the transactions contemplated by
this Agreement are consummated or this Agreement is terminated, the Company agrees to pay or cause to be paid all costs and expenses incident to the performance of its obligations hereunder, including without limitation, (i) the costs incident
to the authorization, issuance, sale, preparation and delivery of the Securities and any taxes payable in that connection; (ii) the costs incident to the preparation and printing of the Preliminary Offering Memorandum, any other Time of Sale
Information and the Offering Memorandum (including any amendment or supplement thereto) and the distribution thereof; (iii) the costs of reproducing and distributing each of the Transaction Documents; (iv) the fees and expenses of the
Company’s counsel and independent accountants; (v) the fees and expenses incurred in connection with the registration or qualification and determination of eligibility for investment of the Securities under the laws of such jurisdictions
as the Representatives may designate; (vi) any fees charged by rating agencies for rating the Securities; (vii) the fees and expenses of the Trustee and any paying agent (including related fees and expenses of any counsel to such parties);
(viii) all expenses and application fees incurred in connection with the application for the inclusion of the Securities on the PORTAL Market and the approval of the Securities for book-entry transfer by DTC; (ix) any fees or costs
incident to listing the Underlying Securities on the Exchange; and (x) all expenses incurred by the Company in connection with any “road show” presentation to potential investors. 
 (b) If (i) this Agreement is terminated pursuant to Section 8, (ii) the Company for any reason fails to tender the
Securities for delivery to the Initial Purchasers or (iii) the Initial Purchasers decline to purchase the Securities for any reason permitted under this Agreement, the Company agrees to reimburse the Initial Purchasers for all out-of-pocket
costs and expenses (including the fees and expenses of their counsel) reasonably incurred by the Initial Purchasers in connection with this Agreement and the offering contemplated hereby. 
  

 27 

 11. Persons Entitled to Benefit of Agreement. This Agreement shall inure to the benefit of and be
binding upon the parties hereto and their respective successors and any controlling persons referred to herein, and the affiliates, officers and directors of each Initial Purchaser referred to in Section 7 hereof and the directors and officers
of the Company. Nothing in this Agreement is intended or shall be construed to give any other person any legal or equitable right, remedy or claim under or in respect of this Agreement or any provision contained herein. No purchaser of Securities
from any Initial Purchaser shall be deemed to be a successor merely by reason of such purchase. 
 12. Survival. The respective
indemnities, rights of contribution, representations, warranties and agreements of the Company and the Initial Purchasers contained in this Agreement or made by or on behalf of the Company or the Initial Purchasers pursuant to this Agreement or any
certificate delivered pursuant hereto shall survive the delivery of and payment for the Securities and shall remain in full force and effect, regardless of any investigation made by or on behalf of the Company or the Initial Purchasers. Sections 7
and 10 of this Agreement shall survive any termination of this Agreement. 
 13. Certain Defined Terms. For purposes of this
Agreement, (a) except where otherwise expressly provided, the term “affiliate” has the meaning set forth in Rule 405 under the Securities Act; (b) the term “business day” means any day other than a day on which banks
are permitted or required to be closed in New York City; (c) the term “Exchange Act” means the Securities Exchange Act of 1934, as amended; (d) the term “subsidiary” has the meaning set forth in Rule 405 under the
Securities Act; (e) the term “written communication” has the meaning set forth in Rule 405 under the Securities Act; and (f) the term “significant subsidiary” has the meaning set forth in Rule 1-02 of Regulation S-X
under the Exchange Act. 
 14. Miscellaneous. 
 (a) Authority of the Representatives. Any action by the Initial Purchasers hereunder may be taken by J.P. Morgan Securities Inc. on
behalf of the Initial Purchasers, and any such action taken by J.P. Morgan Securities Inc. shall be binding upon the Initial Purchasers. 
 (b) Notices. All notices and other communications hereunder shall be in
writing and shall be deemed to have been duly given if mailed or transmitted and confirmed by any standard form of telecommunication. Notices to the Initial Purchasers shall be given to the Representatives c/o J.P. Morgan Securities Inc., 277 Park

 (c) Governing Law. This Agreement shall be governed by and construed in accordance with
the laws of the State of New York. 
  

 28 

 (d) Counterparts. This Agreement may be signed in counterparts (which may include
counterparts delivered by any standard form of telecommunication), each of which shall be an original and all of which together shall constitute one and the same instrument.

therefrom, shall in any event be effective unless the same shall be in writing and signed by the parties hereto.

 If the stock price is between two stock price amounts in the table or the effective date is between two effective dates in the table, the number of additional shares
will be determined by a straight-line interpolation between the number of additional shares set forth for the higher and lower stock price amounts and the two dates, as applicable, based on a 365-day year; 
 If the stock price is greater than $110.00 per share (subject to adjustment), no additional shares will be added to the conversion rate; and 
 If the stock price is less than $45.54 per share (subject to adjustment), no additional shares will be added to the conversion rate. 
 Notwithstanding the foregoing, in no event will the total number of shares of common stock issuable upon conversion exceed 21.9587 per $1,000 principal amount of
notes, subject to adjustments in the same manner as the conversion rate as set forth in the Preliminary Offering Memorandum under the heading, ‘Description of notes — Conversion rights — Conversion rate adjustments.’Fortieth Supplemental Indenture

 AND IT IS HEREBY COVENANTED, DECLARED AND AGREED, by and between the parties hereto for the benefit of
those who shall hold the Bonds and coupons, or any of them, to be issued under the Indenture as follows: 
 ARTICLE I 
 DESCRIPTION OF BONDS OF THE 2047 SERIES 
 Section 1. General Description of Bonds of the 2047 Series. The Bonds of the 2047 Series to be executed, authenticated and
delivered under and secured by the Original Indenture shall be designated as “First Mortgage Bonds, 6.10% Series due 2047” of the Company. The Bonds of the 2047 Series shall be executed, authenticated and delivered in accordance with the
provisions of, and shall in all respects be subject to, all of the terms, conditions and covenants of the Indenture and subject to all the terms, conditions and covenants of this Supplemental Indenture. 
 Bonds of the 2047 Series shall mature May 15, 2047 and shall bear interest at the rate of six and ten one-hundredths percent (6.10%) per annum
payable quarterly on the fifteenth day of May, August, November and February in each year, commencing August 15, 2007. Every Bond of the 2047 Series shall be dated the date of authentication except that, notwithstanding the provisions of
Section 6 of Article II of the Original Indenture, if any Bond of the 2047 Series shall be authenticated at any time subsequent to the record date (as hereinafter in this Section defined) for any interest payment date but prior to the day
following such interest payment date, it shall be dated as of the day following such interest payment date, provided, however, if at the time of authentication of any Bond of the 2047 Series interest shall be in default on any Bonds of
the 2047 Series, such Bond shall be dated as of the day following the interest payment date to which interest has previously been paid in full or made available for payment in full on outstanding Bonds of the 2047 Series, as the case may be, or, if
no interest has been paid or made available for payment, as of the date of initial authentication and delivery of such Bond. Every Bond of the 2047 Series shall bear interest from the May 15, August 15, November 15 or February 15
next preceding the date thereof, unless such Bond shall be dated prior to August 15, 2007, in which case it shall bear interest from May 16, 2007. 
 The person in whose name any Bond of the 2047 Series is registered at the close of business on any record date with regard to any interest payment date shall be entitled to receive the interest payable thereon on such
interest payment date notwithstanding the cancellation of such Bond upon the transfer or exchange thereof subsequent to such record date and prior to the day following such interest payment date, unless the Company shall default in the payment of
the interest due on such interest payment date, in which case such defaulted interest shall be paid to the person in whose name such Bond is registered on the date of payment of 

  

 7 

 
such defaulted interest. The term “record date” as used in this Section with regard to any May 15, August 15, November 15 and
February 15 interest payment date shall mean the close of business on the next preceding May 1, August 1, November 1 and February 1, respectively, or if such day is not a business day, the business day next preceding such
day. The Bonds of the 2047 Series shall be payable as to principal, premium, if any, and interest, in any coin or currency of the United States of America which at the time of payment is legal tender for public and private debts, at the agency of
the Company in the City of Chicago, Illinois, or at the option of the holder thereof at the agency of the Company in the Borough of Manhattan, The City of New York, provided that at the option of the Company interest may be paid by check
mailed to the holder at such holder’s registered address. 
 Section 2. Denominations of Bonds of the 2047 Series and
Privilege of Exchange. The Bonds of the 2047 Series shall be registered bonds without coupons of the denominations of $25 and of any multiples of $25, numbered consecutively from R-1. Bonds of the 2047 Series may each be interchanged for other
Bonds within the same Series in authorized denominations and in the same aggregate principal amounts, without charge, except for any tax or governmental charge imposed in connection with such interchange. 
 Section 3. Form of Bonds of the 2047 Series. The Bonds of the 2047 Series, and the Trustee’s Certificate with respect thereto,
shall be substantially in the following forms, respectively:

debts, and to pay interest thereon in like coin or currency from the fifteenth day of May, August, November and February next preceding the date of this Bond
(the “Bonds”) unless this Bond shall be dated prior to August 15, 2007, in which case from May 16, 2007 at the rate of six and ten one-hundredths percent (6.10%) per annum, payable quarterly, on
May 15, August 15, November 15 and February 15 of each year, commencing August 15, 2007, until maturity, or, if this Bond shall be duly called for redemption or submitted for repurchase, until the redemption date
or repurchase date, as the case may be, or, if the Company shall default in the payment of the principal or premium hereof, until the Company’s obligation with respect to the payment of such principal or premium shall be discharged as provided
in the Indenture hereinafter mentioned. The interest payable on any May 15, August 15, November 15 or February 15 interest payment date as aforesaid will be paid to the person in whose name this Bond is registered at the close of
business on the next preceding May 1, August 1, November 1 and February 1, respectively, or if such day is not a business day, the business day next preceding such day (the “record date”), unless the Company
shall default in the payment of the interest due on such interest payment date, in which case such defaulted interest shall be paid to the person in whose name this Bond is registered on the date of payment of such defaulted interest. Principal of,
premium, if any, and interest on, this Bond are payable at the agency of the Company in the City of Chicago, Illinois in immediately available funds, or at the option of the holder thereof at the agency of the Company in the Borough of Manhattan,
The City of New York, provided that at the option of the Company interest may be paid by check mailed to the holder at such holder’s registered address. 
 This Bond is one of a duly authorized issue of Bonds of the Company (herein called the “Bonds”), in unlimited aggregate principal amount, of the series hereinafter specified, all issued and to be
issued under and equally secured by a Mortgage and Deed of Trust, dated July 1, 1939 (the “Original Mortgage”), executed by the Company to The Bank of New York Trust Company, N.A. (herein called the “Trustee”),
as Trustee (as successor to Harris Trust and Savings Bank), as amended by indentures supplemental thereto including the fortieth indenture supplemental thereto dated as of May 15, 2007 (herein called the “Supplemental
Indenture”), between the Company and the Trustee (said Original Mortgage, as so amended, being herein called the “Indenture”), to which Indenture and all indentures supplemental thereto reference is hereby made for a
description of the properties mortgaged and pledged, the nature and extent of the security, the rights of the bearers or registered owners of the Bonds and of the Trustee in respect thereto, and the terms and conditions upon which the Bonds are, and
are to be, secured. The Bonds may be issued in series, for various principal sums, may mature at different times, may bear interest at different rates and may otherwise vary as in the Indenture provided. This Bond is one of a series designated as
the “First Mortgage Bonds, 6.10% Series due 2047” (herein called “Bonds of the 2047 Series”) of the Company, issued under and secured by the Indenture executed by the Company to the Trustee. 
 To the extent permitted by, and as provided in the Indenture, modifications or alterations of the Indenture or of any indenture supplemental thereto, and
of the rights and obligations of the Company and of the holders of the Bonds and coupons, may be made with the consent of the Company by an affirmative vote of not less than 60% in principal amount of the Bonds entitled to vote then outstanding, at
a meeting of 

  

 10 

 
Bondholders called and held as provided in the Indenture, and by an affirmative vote of not less than 60% in principal amount of the Bonds of any series
entitled to vote then outstanding and affected by such modification or alteration, in case one or more but less than all of the series of Bonds then outstanding under the Indenture are so affected. No modification or alteration shall be made which
will affect the terms of payment of the principal of or premium, if any, or interest on, this Bond, which are unconditional. The Company has reserved the right to make certain amendments to the Indenture, without any consent or other action by
holders of the Bonds of this series (i) to the extent necessary from time to time to qualify the Indenture under the Trust Indenture Act of 1939, (ii) to delete the requirement that the Company meet a net earnings test as a condition to
authenticating additional Bonds or merging into another company, (iii) to make certain other amendments which make the provisions for the release of mortgaged property less restrictive and (iv) to make certain other amendments, all as more
fully provided in the Indenture and in the Supplemental Indenture. In addition, once all Bonds issued prior to January 1, 1997 are no longer outstanding, the Company will be permitted to issue additional Bonds in an amount equal to 70% of the
value of net bondable property additions not subject to an unfunded prior lien, as provided in the Original Mortgage. 
 On and after
May 15, 2012, this Bond is subject to redemption, in whole or in part, at any time at the option of the Company at a price equal to 100% of the principal amount redeemed plus accrued and unpaid interest to the redemption date as provided in the
Supplemental Indenture. Such redemption in every case shall be effected upon notice given by: (1) first class mail, postage prepaid, at least thirty days and not more than sixty days prior to the redemption date, to the registered owners of
such Bonds at their addresses as the same shall appear on the transfer register of the Company; and (2) stating, among other things, the redemption price and date, in each case, subject to the conditions of and as more fully set forth in the
Indenture. 
 Notwithstanding the foregoing, a notice of redemption may provide that the optional redemption described in such notice is
conditioned upon the occurrence of certain events before the date of redemption. Such notice of conditional redemption will be of no effect unless all such conditions to the redemption shall have occurred before the redemption date or shall have
been waived by the Company. 
 In case an event of default, as defined in the Indenture, shall occur, the principal of all of the Bonds at
any such time outstanding under the Indenture may be declared or may become due and payable, upon the conditions and in the manner and with the effect provided in the Indenture. The Indenture provides that such declaration may in certain events be
waived by the holders of a majority in principal amount of the Bonds outstanding. 
 This Bond is transferable by the registered owner
hereof, in person or by duly authorized attorney, on the books of the Company to be kept for that purpose at the agency of the Company in the City of Chicago, Illinois, and at the agency of the Company in the Borough of Manhattan, The City of New
York, upon surrender and cancellation of this Bond and on presentation of a duly executed written instrument of transfer, and thereupon a new registered Bond or Bonds of the same series, of the same aggregate principal amount and in authorized
denominations will be issued to the 

  

 11 

 
transferee or transferees in exchange herefor; and this Bond, with or without others of like form and series, may in like manner be exchanged for one or more
new registered Bonds of the same series of other authorized denominations but of the same aggregate principal amount; all upon payment of the charges and subject to the terms and conditions set forth in the Indenture. 
 The Company or a successor entity may deliver to the Trustee in substitution for any Bonds of the 2047 Series, mortgage bonds or other similar
instruments as set forth in the Indenture. 
 Subject to the preceding sentence, no recourse shall be had for the payment of the principal of
or premium, if any, or interest on this Bond, or for any claim based hereon or on the Indenture or any indenture supplemental thereto, against any incorporator, or against any stockholder, director or officer, past, present or future, of the
Company, or of any predecessor or successor corporation, as such, either directly or through the Company or any such predecessor or successor corporation, whether by virtue of any constitution, statute or rule of law, or by the enforcement of any
assessment or penalty or otherwise, all such liability, whether at common law, in equity, by any constitution, statute or otherwise, of incorporators, stockholders, directors or officers being released by every owner hereof by the acceptance of this
Bond and as part of the consideration for the issue hereof, and being likewise released by the terms of the Indenture. 
 No director,
officer, employee or stockholder of the Company will have any liability for any obligations of the Company under the Bonds or Indenture or for any claim based on, in respect of, or by reason of, such obligations or their creation. Each holder by
accepting a Bond waives and releases all such liability. The waiver and release are part of the consideration for issuance of the Bonds. The waiver may not be effective to waive liabilities under the federal securities laws. It is the view of the
Securities and Exchange Commission that this type of waiver is against public policy. 
 This Bond shall not be entitled to any benefit under
the Indenture or any indenture supplemental thereto, or become valid or obligatory for any purpose, until The Bank of New York Trust Company, N.A., the Trustee (as successor to Harris Trust and Savings Bank) under the Indenture, or a successor
trustee thereto under the Indenture, shall have signed the form of certificate endorsed hereon.

 STATEMENT OF INSURANCE 
 Financial Guaranty Insurance Company (“Financial Guaranty”), a New York stock insurance company, has issued a surety bond, policy number 07010206 (the “Policy”) containing the
following provisions with respect to the Bonds, such Policy being on file at the principal office of The Bank of New York Trust Company, N.A. or its successor, as Paying Agent for the Bonds (the “Paying Agent”). 
 Financial Guaranty hereby unconditionally and irrevocably agrees to pay to U.S. Bank Trust National Association or its successor, as its agent (the
“Fiscal Agent”) for the benefit of the Bondholders, that portion of the principal of and interest on the Bonds which shall become due for payment and which Westar Energy, Inc., as the issuer of the Bonds (the
“Issuer”), shall have failed to provide. “Due for payment” means, with respect to principal of a Bond, the stated maturity date thereof and does not refer to any earlier date on which payment of principal of the
Bonds is due by reason of call for redemption, acceleration or other advancement of maturity, and with respect to interest on a Bond, the stated date for payment of such interest. 
 Upon receipt of telephonic or telegraphic notice, subsequently confirmed in writing, or written notice by registered or certified mail, from a Bondholder
or the Paying Agent to Financial Guaranty that the Issuer has failed to provide sufficient funds to the Paying Agent for payment in full of all principal and interest due for payment on such Bond, Financial Guaranty on the date such principal or
interest becomes due for payment or on the business day next following the day on which Financial Guaranty shall have received such notice of nonpayment, whichever is later, will make a deposit of funds, in an account with the Fiscal Agent,
sufficient to make the portion of such payment not paid by the Issuer. Upon presentation to the Fiscal Agent of evidence reasonably satisfactory to it of the Bondholder’s right to receive such payment and any appropriate instruments of
assignment required to vest all of such Bondholder’s right to such payment in Financial Guaranty, the Fiscal Agent will disburse such amount to the Bondholder. 
 As used herein the term “Bondholder” means the person other than the Issuer who at the time of nonpayment of a Bond is entitled under the terms of such Bond to payment thereof. 
 This policy is non-cancellable for any reason.

 ARTICLE III

 REDEMPTION AND SUBSTITUTION OF BONDS OF
THE 2047 SERIES 
 Section 1. Optional Redemption of Bonds of the 2047 Series.

 (1) Optional Redemption of Bonds of the 2047 Series. At any time, and from time to time, on or after May 15, 2012, the Company
may redeem all or any portion of the Bonds of the 2047 Series, after giving the required notice under subsection (2) of this Article III, Section 1, at a redemption price equal to 100% of the principal amount of the Bonds of the 2047
Series to be redeemed, plus any accrued and unpaid interest thereon to the redemption date. 
 (2) Notice of Redemption. Subject to
the provisions of Article V of the Original Indenture, in the case of redeeming all or any portion of the Bonds of the 2047 Series, the Company shall cause notice of redemption to be given by (1) first class mail, postage prepaid, at least

promptly notify the Trustee in writing that the conditions precedent to such redemption have failed to occur and the Bonds of the 2047 Series will not be redeemed.

enforceable in accordance with their terms, except as limited by bankruptcy, insolvency or other laws affecting the enforcement of mortgagees’ and other creditors’ rights and shall be entitled to the benefit of the mortgage and deed of
trust or other similar instrument pursuant to which they shall have been issued and (vi) such other certificates and documents with respect to the issuance and delivery of the 2047 Series Substituted Mortgage Bonds as may be required by
law or as the Trustee may reasonably request.

 (e) The definition of the term “net earnings available for interest, depreciation and property
retirement,” as contained in Article I of the Original Indenture, shall be deemed to mean the net earnings of the Company ascertained as follows: 
 (i) The total operating revenues of the Company and the net non-operating revenues of the properties of the Company shall be ascertained: 
 (A) From the total, determined as provided in Subsection (a), there shall be deducted all operating expenses, including all salaries,
rentals, insurance, license and franchise fees, expenditures for repairs and maintenance, taxes (other than income, excess profits and other taxes measured by or dependent on net taxable income), depreciation as shown on the books of the Company or
an amount equal to the minimum provision for depreciation as hereinafter defined, whichever is greater, but excluding all property retirement appropriations, all interest and sinking fund charges, amortization of stock and debt discount and expense
or premium and further excluding any charges to income or otherwise for the amortization of plant or property accounts or of amounts transferred therefrom. 
 (B) The balance remaining after the deduction of the total amount computed pursuant to Subsection (b) from the total amount computed pursuant to Subsection (a) shall constitute the “net earnings of the
Company available for interest,” provided that not more than fifteen percent (15%) of the net earnings of the Company available for interest may consist of the aggregate of (1) net non-operating income, (2) net earnings
from mortgaged property other than property of the character of property additions and (3) net earnings from property not subject to the lien of this Indenture. 
 (C) No income received or accrued by the Company from securities and no profits or losses of capital assets shall be included in making
the computations aforesaid. 
 (D) In case the Company shall have acquired any acquired plant or systems or shall have been
consolidated or merged with any other corporation, within or after the particular period for which the calculation of net earnings of the Company 

  

 25 

 
available for interest, depreciation and property retirement is made, then, in computing the net earnings of the Company available for interest, depreciation
and property retirement, there may be included, to the extent they may not have been otherwise included, the net earnings or net losses of such acquired plant or system or of such other corporation, as the case may be, for the whole of such period.
The net earnings or net losses of such property additions, or of such other corporation for the period preceding such acquisition or such consolidation or merger, shall be ascertained and computed as provided in the foregoing subsections of this
definition as if such acquired plant or system had been owned by the Company during the whole of such period, or as if such other corporation had been consolidated or merged with the Company prior to the first day of such period. 
 (E) In case the Company shall have obtained the release of any property pursuant to Section 3 of Article VII of the Original
Indenture, of a fair value in excess of Five Hundred Thousand Dollars ($500,000), as shown by the engineer’s certificate required by said Section 3, or shall have obtained the release of any property pursuant to Section 5 of
Article VII of the Original Indenture, the proceeds of which shall have exceeded Five Hundred Thousand Dollars ($500,000), within or after the particular period for which the calculation of net earnings of the Company available for interest,
depreciation and property retirement is made, then, in computing the net earnings of the Company available for interest, depreciation and property retirement, the net earnings or net losses of such property for the whole of such period shall be
excluded to the extent practicable on the basis of actual earnings and expenses of such property or on the basis of such estimates of the earnings and expenses of such property as the signers of an officers’ certificate filed with the Trustee
pursuant to Section 3(b) of Article III or Section 16 of Article IV of the Original Indenture shall deem proper. 
 (ii) The term “minimum charge for depreciation” as used herein shall mean an amount equal to (A) fifteen percent (15%) of the total operating revenues of the Company after deducting therefrom an amount equal to
the aggregate cost to the Company of electric energy, gas and water purchased for resale to others and rentals paid for, or other payments made for the use of, property owned by others and leased to or operated by the Company, the maintenance of
which and depreciation on which are borne by the owners, less (B) an amount equal to the expenditures for maintenance and repairs to the plants and property of the Company and included or reflected in its operating expense accounts. 

 

 26 

 (iii) The terms “net earnings available for interest, depreciation and property
retirement” and “net earnings of another corporation available for interest, depreciation and property retirement” as contained in Article I of the Original Indenture, when used with respect to any property or with respect
to another corporation, shall mean the net earnings of such property or the net earnings of such other corporation, as the case may be, computed in the manner provided in Subsections (a), (b), (c) and (d) hereof. 
 (f) Notwithstanding the provisions of clauses (1) and (2) of subsection (b) of Article III, and Subsection (b) of
Section 14 of Article IV, and Subsection (b) of Section 16 of Article IV and clause (2) of Subsection (b) of Section 1 of Article XII of the Original Indenture, the computation of net earnings required therein
shall be made as provided in Subsection (e) of this Section 1, and the net earnings tests required in said mentioned provisions of Articles III, IV and XII of the Original Indenture shall be based on two times the annual interest charges
described in such provisions, instead of two and one-half times such charges, but shall not otherwise affect such provisions or relieve from the requirements therein pertaining to ten percent (10%) of the principal amount of Bonds therein
described. 
 Section 2. Facsimile Signatures. All of the Bonds of the 2047 Series and of any series initially
issued after the initial issuance of Bonds of the 2047 Series shall, from time to time, be executed on behalf of the Company by its Chairman of the Board, Chief Executive Officer, President or one of its Vice Presidents whose signature,
notwithstanding the provisions of Section 12 of Article II of the Original Indenture, may be by facsimile, and its corporate seal (which may be in facsimile) shall be thereunto affixed and attested by its Secretary or one of its Assistant
Secretaries whose signature, notwithstanding the provisions of the aforesaid Section 12, may be by facsimile. 
 In case any of the
officers who have signed or sealed any of the Bonds of the 2047 Series or of any series initially issued after the initial issuance of Bonds of the 2047 Series manually or by facsimile shall cease to be such officers of the Company before
such Bonds so signed and sealed shall have been actually authenticated by the Trustee or delivered by the Company, such Bonds nevertheless may be authenticated, issued and delivered with the same force and effect as though the person or persons who
so signed or sealed such Bonds had not ceased to be such officer or officers of the Company; and also any such Bonds may be signed or sealed by manual or facsimile signature on behalf of the Company by such persons as at the actual date of the
execution of any of such Bonds shall be the proper officers of the Company, although at the nominal date of any such Bond any such person shall not have been such officer of the Company.
