2009 Executive Bonus Plan, as amended

 Exhibit 10.2 
 VMware, Inc. 
 2009 Executive Bonus Program 
 Amended and Restated April 14, 2009 
 Executive Bonus Program Objectives 
 Among the objectives of the VMware Bonus Program – 2009 are to: 
  

	 	•	 	 motivate our executives to achieve our strategic, operational and financial goals 

  

	 	•	 	 reward superior performance 

  

	 	•	 	 attract and retain exceptional executives; and 

  

	 	•	 	 reward behaviors that result in long term increased stockholder value 

 Overview 
 The Compensation and Corporate Governance Committee has adopted a cash bonus program relating to
performance in 2009 (the “2009 Program”) under the 2007 Equity and Incentive Plan (the “Plan”) providing for possible cash bonuses to specified executives of VMware, Inc. and its consolidated subsidiaries (the
“Company”). Unless otherwise indicated herein, provisions of the Plan shall apply to the 2009 Program. 
 In keeping with VMware’s philosophy
of tying a substantial portion of our executive compensation to the achievement of measurable achievements, a goals-based cash bonus program has been developed and implemented. The determination of bonus payout will be made semiannually after the
conclusion of the semi-annual measurement periods ending on June 30 and December 31 based on results achieved by the company, as reported to the Compensation and Corporate Governance Committee by the Corporate Controller. Bonuses will be
determined by the Compensation and Corporate Governance Committee of the Board of Directors (the “Administrator”). Bonus payments will only occur if certain predetermined company and individual (“MBO”) objectives are successfully
achieved. Bonus amounts will be calculated (“Calculated Bonus Amounts”) based upon the degree of achievement of the predetermined objectives. The Compensation and Corporate Governance Committee shall determine final bonus payouts and, in
its discretion, taking into account review and discussion of recommendations made by the Chief Executive Officer, may reduce, but not increase, final bonus payouts from the Calculated Bonus Amounts. 
 Bonus awards represent an unfunded, unsecured promise by the Company to pay a bonus amount determined by the Compensation and Corporate Governance Committee to each
Participant, but only upon satisfaction of the performance criteria determined by the Compensation and Corporate Governance Committee in accordance with the provisions set forth below. 
 Eligibility 
 All senior executives are eligible to be considered for participation. However, no person is
automatically entitled to participate in the 2009 Program. Participants will be approved solely at the discretion of the Compensation and Corporate Governance Committee and may be amended at any time by the Compensation and Corporate Governance
Committee. Additionally, the executive must be an employee of the Company at the time the bonus is paid out in order to vest in right to receive payment. 
 Participants may include officers of the Company as defined under Rule 16a-1 of the 1934 Securities Exchange Act (“Section 16 Officers”) and other senior executives who are not Section 16 Officers. At its discretion, the
Compensation and Corporate Governance Committee may delegate authority to the Chief Executive Officer to add senior executives who are not Section 16 Officers to the 2009 Program.

 Administration 
 As Administrator, the Compensation and Corporate Governance Committee is ultimately responsible for administering the 2009 Program. The Administrator has all powers and discretion necessary or appropriate to review and approve the 2009
Program and its operation, including, but not limited to, the power to (a) determine Participants, (b) interpret the provisions of the 2009 Program, (c) adopt rules for the administration, interpretation and application of the 2009
Program consistent with the Plan, and (d) interpret, amend or revoke any such rules. All determinations and decisions made by the Administrator and any decision of the Administrator shall be final, conclusive, and binding on all persons, and
shall be given the maximum deference permitted by law. The Administrator, in its sole discretion, may amend or terminate the 2009 Program, or any part thereof, at any time and for any reason, subject to the limitations set forth in Sections 3,
6(b)(iv) and 7 of the Plan. 
 The Administrator shall exercise full authority to make final determinations with respect to bonuses granted under the 2009
Program to Section 16 Officers. The Administrator may, in its discretion, delegate authority over bonuses to Participants who are not Section 16 Officers to the Chief Executive Officer of the Company. 
 Target Percentage 
 The Administrator shall establish target
bonuses (“Bonus Targets”) and bonus formulas for the 2009 Program. 
 Target bonus amounts will be a percentage of a Participant’s semi-annual
base salary as of the date the target bonus percentage is established (the “Target Bonus Percentage”). 
 The Calculated Bonus Amount, if any, may
range 0% to 200% of the Target Bonus Percentage depending upon performance achievement. Minimum bonus thresholds are described below. 
 Performance
Period 
 Unless otherwise indicated, the performance periods for bonuses granted under the 2009 Program shall run from January 1, 2009 to
June 30, 2009 and from July 1, 2009 to December 31, 2009. (each, a “Performance Period”). Participants are rewarded during the period that they are actively employed by VMware. 
 Participants are not eligible to participate in any other Company bonus or incentive plan during a Performance Period. This exclusion does not apply, however, to
applicable employee referral bonuses, spot bonuses, equity awards, or Company contributions to qualified retirement or savings plans. 
 New Hires: Calculated Bonus Amounts will be prorated for newly hired participants based on the number of days they are employed during the Performance Period. 
 Leaves of Absence: Calculated Bonus Amounts will be prorated for any time during the Performance Period that a Participant is on an unpaid leave of
absence status. Unpaid leaves of absence exclude those absences for which vacation, sick leave or other compensation is paid directly by the Company. Unpaid absences include those absences for which compensation is received from any source other
than directly from the Company. 
 Changes in Position: Participants who move from one 2009 bonus-eligible position to a different 2009
bonus-eligible position with a different target bonus percentage may earn a target bonus prorated on base pay and bonus at the start of each period. 
 Termination: In order to vest and the right to receive a bonus under the 2009 Program, an employee must be in an active employment status or on approved leave at the day the bonus is paid out. An employee whose employment ends for
any reason prior to that date will not earn and will not be paid any bonus under this 2009 Program. 
  

 Page 2 

 The Compensation and Corporate Governance Committee shall have the exclusive discretion to determine when a Participant
is no longer actively employed for purposes of the 2009 Program. Participants have no right or interest in any bonus and such bonus is not earned unless the Administrator determines a bonus payout is due. 
 Performance Metrics 
 The Calculated Bonus Amount will depend
on both a company component (“Corporate Financial Metric”) and an individual component (“MBO”) selected from the performance goals from the 2007 Plan. The Company must meet a threshold of 80% of the Corporate Financial Metric in
order for any bonus payouts to be made. If the 80% threshold is not achieved, the 2009 Program shall not be funded and no bonus payouts shall be made. The Corporate Financial Metrics, the MBO’s and their relative weighting shall be determined
by the Committee within 45 days of the commencement of the performance period. 
 Corporate Financial Metric Component  
 The Corporate Financial Metric shall be determined by calculating success against company-wide financial metrics and, as applicable, business unit performance metrics, as
determined by the Compensation and Corporate Governance Committee. 
 MBO (Individual) Component 
 Each Participant will be assigned individual performance goals by the Compensation and Corporate Governance Committee that are appropriate to the Participant’s role
at the Company. If threshold achievement of 80% of the Corporate Financial Metric is met, then the MBO component is funded at the same percentage as the Corporate Financial Metric. The Compensation and Corporate Governance Committee can exercise
negative discretion to reduce the bonus for the MBO component. In making its determination whether to reduce the bonus for the MBO component, the Committee’s shall review and discuss the Chief Executive Officer’s assessment of each
Participant’s achievement of his or her individual performance goals. 
 Bonus Determination and Payment 
 The Compensation and Corporate Governance Committee shall determine final bonus payouts to Participants based upon achievement of the foregoing metrics and goals. The
Committee reserves the right to reduce bonus payouts below Calculated Bonus Amounts or not make any bonus payouts in its sole discretion. 
 Cancellation, Rescission and Recoupment of Awards 
 Any bonus granted under this 2009 Program to a Participant shall be subject to
cancellation, rescission, repayment or other action at the discretion of the Compensation Committee as set forth in Section 7(c) of the Plan in the event that such Participant engages in “Detrimental Activity” as such term is defined
in Section 7(c) 
 Additionally, the Compensation and Corporate Governance Committee shall have the discretion to require that each Participant
reimburse the Company for all or any portion of any bonuses paid under the 2009 Program if – 
 (a) the payment was predicated upon the
achievement of certain financial results that were subsequently the subject of a material financial restatement, 
  

 Page 3 

 (b) in the Board’s view, the Participant engaged in fraud or misconduct that caused or partially
caused the need for a material financial restatement by the Company or any substantial affiliate, and 
 (c) a lower payment, award, or
vesting would have occurred based upon the restated financial results. 
 In each such instance, upon the determination of the Compensation and Corporate
Governance Committee to require recoupment of a previously paid bonus awarded under the 2009 Program, the Company will, to the extent practicable and allowable under applicable laws, require reimbursement of any bonus awarded for the relevant period
exceeded the lower payment that would have been made based on the restated financial results, provided that the Company will not seek to recover bonuses compensation paid more than three years prior to the date the applicable restatement is
disclosed. 
 At-Will Employment (US Only) 
 This
Plan does not affect the terminable-at-will status of the employment relationship. Neither the attainment of goals nor the continuous service requirement necessary to earn a bonus alters the ability of an employee or the Company to terminate
employment at any time, with or without reason and with or without advance notice.

 The Company further covenants and agrees to and with the Trustees and their successors in said trust under the Mortgage, as follows:

 ARTICLE I 
 SIXTIETH SERIES OF
BONDS 
 SECTION 1. There shall be a series of bonds designated “6.70% Series due 2019” (herein sometimes referred to as the
“Bonds of the Sixtieth Series”), each of which shall also bear the descriptive title, First Mortgage Bond, and the form thereof, which is established by Resolution of the Board of Directors of the Company, is attached hereto as
Exhibit A. Bonds of the Sixtieth Series shall be limited to $300,000,000 in aggregate principal amount, except as provided in Section 16 of the Mortgage, shall mature on June 15, 2019, and shall be issued as fully registered bonds in
denominations of Two Thousand Dollars and in any multiple or multiples of One Thousand Dollars in excess thereof. Bonds of the Sixtieth Series shall bear interest from the date of their issuance at the rate of 6.70% per annum, payable
semi-annually on June 15 and December 15 of each year, beginning December 15, 2009, to holders of record on the preceding June 1 or December 1, as applicable, whether or not a business day. The principal of, redemption
premium, if any, and interest on Bonds of the Sixtieth Series shall be payable at the office or agency of the Company in the Borough of Manhattan, The City of New York, in such coin or currency of the United States of America as at the time of
payment is legal tender for public and private debts, except as follows. Payments in respect of the Bonds of the Sixtieth Series represented by Global Bonds (as defined below) (including principal, redemption premium, if any, and interest) will be
made by wire transfer of immediately available funds to the accounts specified by The Depository Trust Company (together with any successor, the “Depository”). Payments of interest in respect of physical bonds will be made by mailing a
check to the registered address of each Holder thereof; provided, however, that payments on a physical bond will be made by wire transfer to a U.S. Dollar account maintained by the payee 

 
with a bank in the United States if such holder certifies to the Company that it is a Holder of Bonds of the Sixtieth Series in an aggregate principal amount
equal to or greater than $10,000,000 and elects payment by wire transfer by giving written notice to the Corporate Trustee to such effect designating such account no later than 30 days immediately preceding the relevant due date for payment (or such
other date as the Corporate Trustee may accept in its discretion). 
 If an interest payment date or a redemption date falls
on a day that is not a business day, such interest payment date or redemption date, as the case may be, shall be the immediately succeeding business day with the same force and effect as if made on the original interest payment date or redemption
date, as the case may be, and no interest shall accrue for the period from and after such original interest payment date or redemption date, as the case may be. 
 Interest on the Bonds of the Sixtieth Series shall be computed on the basis of a 360 day year consisting of twelve 30 day months.

 SECTION 2. Bonds of the Sixtieth Series shall be dated as in Section 10 of the Mortgage provided. 
 SECTION 3. (1) The Bonds of the Sixtieth Series, upon the mailing of notice and with the effect provided in Section 54 of the Mortgage, shall be
redeemable at the option of the Company, as a whole at any time or in part from time to time, at a redemption price equal to the greater of: (a) 100% of the principal amount of the Bonds of the Sixtieth Series to be redeemed, plus accrued and
unpaid interest on Bonds of the Sixtieth Series to be redeemed to the redemption date or (b) as determined by the Quotation Agent, the sum of the present values of the remaining scheduled payments of principal and interest on the Bonds of the
Sixtieth Series to be redeemed (not including any portion of payments of interest accrued as of the redemption date) discounted to the redemption date on a semi-annual basis at the Adjusted Treasury Rate plus fifty (50) basis points, plus
accrued and unpaid interest on those Bonds of the Sixtieth Series to be redeemed to the redemption date. 
 The redemption
price will be calculated assuming a 360-day year consisting of twelve 30-day months. 
 Unless the Company defaults in payment
of the redemption price, on and after the redemption date, interest will cease to accrue on the Bonds of the Sixtieth Series or portions of the Bonds of the Sixtieth Series called for redemption. 
 (2) Notice of Redemption. In the case of redeeming all or any portion of the Bonds of the Sixtieth Series, the Company shall cause notice
of redemption to be given by (1) first class mail, postage prepaid, at least thirty days and not more than sixty days prior to the date of redemption, to the registered owners of such Bonds of the Sixtieth Series 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. 
 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. If any of these events
fail to occur and are not waived by the Company, the Company will be under no obligation to redeem the Bonds of the Sixtieth Series or pay the holders thereof any redemption proceeds and the Company’s failure to so redeem the Bonds of the
Sixtieth Series will not be considered a default or event of default under the Mortgage. In the event that any of these conditions fail to occur or are not waived by the Company, the Company will promptly notify the Trustee in writing that the
conditions precedent to such redemption have failed to occur and the Bonds of the Sixtieth Series will not be redeemed. 
 “Adjusted Treasury Rate” means, with respect to any redemption date, the rate per annum equal to the semi-annual equivalent yield to maturity of the Comparable Treasury Issue, assuming a price for the Comparable Treasury
Issue (expressed as a percentage of its principal amount) equal to the Comparable Treasury Price for the redemption date. 
 “Business Day” means any day that is not a day on which banking institutions in New York City are authorized or required by law or regulation to close. 
 “Comparable Treasury Issue” means the United States Treasury security selected by the Quotation Agent as having a
maturity comparable to the remaining term of the Bonds that would be used, at the time of selection and in accordance with customary financial practice, in pricing new issues of corporate debt securities of comparable maturity to the remaining term
of the Bonds. 
 “Comparable Treasury Price” means, with respect to any redemption date: 
  

	 	•	 	 the average of the Reference Treasury Dealer Quotations for that redemption date, after excluding the highest and lowest of the Reference Treasury Dealer
Quotations; or 

  

	 	•	 	 if the Quotation Agent obtains fewer than four Reference Treasury Dealer Quotations, the average of all Reference Treasury Dealer Quotations so received.

 “Quotation Agent” means, as selected by the Company, one of the Reference Treasury
Dealers. 
 “Reference Treasury Dealer” means (1) each of BNY Mellon Capital Markets, LLC, Citigroup
Global Markets Inc. and Credit Suisse Securities (USA) LLC and their respective successors, unless either of them ceases to be a primary U.S. Government securities dealer in the United States (“Primary Treasury Dealer”) in which case the
Company shall substitute another Primary Treasury Dealer; and (2) any other Primary Treasury Dealer selected by the Company. 
 “Reference Treasury Dealer Quotations” means, with respect to each Reference Treasury Dealer and any redemption date, the average, as determined by the Quotation Agent, of the bid and asked prices for the Comparable
Treasury Issue (expressed in each case as a percentage of its principal amount) quoted in writing to the Quotation Agent by that Reference Treasury Dealer at 5:00 p.m., New York City time, on the third Business Day preceding that redemption date.

 SECTION 4. Bonds of the Sixtieth Series offered and sold in reliance on Rule 144A shall be issued
initially in the form of one or more Global Bonds (the “Rule 144A Global Bonds”) registered in the name of the Depository or a nominee of the Depository. 
 The Bonds of the Sixtieth Series offered and sold in reliance on Regulation S shall be issued initially in the form of one or more temporary Global Bonds (the “Regulation S Temporary Global Bonds”)
registered in the name of the Depository or a nominee of the Depository. Beneficial interests in a Regulation S Temporary Global Bond will be exchangeable for beneficial interests in a single permanent Global Bond (the “Regulation S
Permanent Global Bond”, together with the Regulation S Temporary Global Bond, the “Regulation S Global Bonds”; the Regulation S Global Bonds, together with the Rule 144A Global Bonds, the “Global Bonds”) on
or after the expiration of the Restricted Period (the “Release Date”) upon the receipt by the Corporate Trustee or its agent of a certificate certifying that the Holder of the beneficial interest in the Regulation S Temporary Global
Bond is a Non-U.S. Person (a “Regulation S Certificate”), substantially in the form set forth in Exhibit D. Each Regulation S Global Bond will be deposited upon issuance with, or on behalf of, a custodian for the Depository for
credit to the respective accounts of the purchasers, or to other accounts as they may direct, at Euroclear (as defined below) or Clearstream (as defined below). Before the Restricted Period, interests in the Regulation S Temporary Global Bond may
only be held through Euroclear or Clearstream, as indirect participants in DTC, unless exchanged for interests in the Rule 144A Global Bond in accordance with the transfer and certification requirements described in Section 6. 
 Upon receipt by the Corporate Trustee of a Regulation S Certificate (a form of which is attached hereto as Exhibit D), (i) with respect to the first
such Regulation S Certificate, the Company shall execute and upon receipt of a Company Order, the Corporate Trustee shall authenticate the Regulation S Permanent Global Bond and (ii) with respect to the first and all subsequent Regulation S
Certificates, the Corporate Trustee shall exchange on behalf of the applicable beneficial owners the portion of the Regulation S Temporary Global Bond covered by such Regulation S Certificates for a Regulation S Permanent Global Bond in an
equivalent aggregate principal amount. Upon any exchange of a portion of a Regulation S Temporary Global Bond for a comparable portion of a Regulation S Permanent Global Bond, the Corporate Trustee shall endorse on the schedules affixed to each of
such Regulation S Global Bond (or on continuations of such schedules affixed to each of such Regulation S Global Bond and made parts thereof) appropriate notations evidencing the date of transfer and (x) with respect to the Regulation S
Temporary Global Bond, a decrease in the principal amount thereof equal to the amount by the applicable certification and (y) with respect to the Regulation S Permanent Global Bond, an increase in the principal amount thereof equal to the
principal amount of the decrease in the Regulation S Temporary Global Bond pursuant to clause (x) above. 
 Bonds of the Sixtieth Series
shall be issued without coupons only in denominations of $2,000 and integral multiples of $1,000 in excess thereof. 
 Each Global Bond shall
be deposited on behalf of the purchasers of Bonds of the Sixtieth Series represented thereby with the Corporate Trustee, as securities custodian (or with such other securities custodian as the Depository may direct), and registered in the name of
the Depository or a nominee of the thereof, duly executed by the Company and authenticated by the Corporate 

 
Trustee as provided herein and in the Mortgage. The aggregate principal amount of the Global Bonds may from time to time be increased or decreased by
adjustments made on the records of the Corporate Trustee and the Depository or its nominee as hereinafter provided.

Company, the Corporate Trustee or any agent of the Company or the Corporate Trustee from giving effect to any written certification, proxy or other authorization furnished by the Depository or impair, as between the Depository and its Agent Members,
the operation of customary practices of such Depository governing the exercise of the rights of a holder of a beneficial interest in any Global Bond.

 SECTION 5. The transfer and exchange of Global Bonds or beneficial interests therein shall be effected through the Depository, in accordance with this

responsible for maintaining a bond register for the registration of Bonds of the Sixtieth Series and registration of transfers thereof (the “Bond Registrar”) a written order given in accordance with the Depository’s procedures
containing information regarding the participant account of the Depository to be credited with a beneficial interest in the Global Bond. The Bond Registrar shall, in accordance with such written order, instruct the Depository to credit to the
account of the person specified in such written order a beneficial interest in the Global Bond and to debit from the account of the Person making the transfer and exchange the beneficial interest in the Global Bond being transferred and exchanged.

 Notwithstanding any other provision of this Supplemental Indenture (other than the provisions set forth in Section 6), a Global Bond
may not be transferred or exchanged as a whole except by the Depository to a nominee of the Depository or by a nominee of the Depository to the Depository or another nominee of the Depository or by the Depository or any such nominee to a successor
Depository or a nominee of such successor Depository. 
 At such time as all beneficial interests in a Global Bond have either been exchanged
for physical bonds, redeemed, purchased or canceled, such Global Bond shall be returned to the Depository for cancellation or retained and canceled by the Corporate Trustee. At any time prior to such cancellation, if any beneficial interest in a
Global Bond is exchanged for physical bonds, redeemed, purchased or canceled, the principal amount of Bonds represented by such Global Bond shall be reduced and an adjustment shall be made on the books and records of the securities custodian with
respect to such Global Bond. 
 The Corporate Trustee shall have no responsibility or obligation to any beneficial owner of a Global Bond,
Agent Member or other person with respect to the accuracy of the records of the Depository or its nominee or of any Agent Member, with respect to any ownership interest in the Bonds of the Sixtieth Series or with respect to the delivery to any Agent
Member, beneficial 

 
owner or other person (other than the Depository) of any notice (including any notice of redemption) or the payment of any amount, under or with respect to
such Bonds of the Sixtieth Series. All notices and communications to be given to the holders and all payments to be made to holders under the Bonds of the Sixtieth Series shall be given or made only to or upon the order of the registered holders
(which shall be the Depository or its nominee in the case of a Global Bond). The rights of beneficial owners in any Global Bond shall be exercised only through the Depository subject to the applicable rules and procedures of the Depository. The
Corporate Trustee may rely and shall be fully protected in relying upon information furnished by the Depository with respect to its Agent Members and any beneficial owners. 
 The Corporate Trustee shall have no obligation or duty to monitor, determine or inquire as to compliance with any restrictions on transfer imposed under
this Supplemental Indenture or under applicable law with respect to any transfer of any interest in any Bond of the Sixtieth Series (including any transfers between or among Agent Members or beneficial owners in any Global Bond) other than to
require delivery of such certificates and other documentation or evidence as are expressly required by, and to do so if and when expressly required by, the terms of the Indenture. 
 SECTION 6. A Global Bond deposited with the Depository or with the Corporate Trustee as securities custodian pursuant to Section 4 shall be
transferred to the beneficial owners thereof in the form of physical bonds in an aggregate principal amount equal to the principal amount of such Global Bond, in exchange for such Global Bond, only if such transfer is required by the third paragraph
of this Section 6. 
 Any Global Bond that is transferable to the beneficial owners thereof pursuant to this Section shall be
surrendered by the Depository to the Corporate Trustee at its corporate trust office to be so transferred, in whole or from time to time in part, without charge, and the Corporate Trustee shall authenticate and deliver, upon such transfer of each
portion of such Global Bond, an equal aggregate principal amount of physical bonds of authorized denominations. Any portion of a Global Bond transferred pursuant to this Section shall be executed, authenticated and delivered only in
denominations of $2,000 principal amount and integral multiples of $1,000 in excess thereof and registered in such names as the Depository shall direct. 
 The Company shall promptly make available to the Corporate Trustee a reasonable supply of physical bonds in definitive, fully registered form without interest coupons if: (i) the Depository notifies the Company
that it is unwilling or unable to continue as a Depository for the Global Bond or if at any time the Depository ceases to be a clearing agency registered under the Exchange Act, as amended, and a successor Depository is not appointed by the Company
within 90 days; or (ii) the Company, at its option, executes and delivers to the Corporate Trustee an order that the Bonds of the Sixtieth Series shall be so exchangeable and the transfer so registrable. 
 In all cases, physical bonds delivered in exchange for any Global Bond or beneficial interests in such Global Bond will be registered in the names, and
issued in any approved denominations, requested by or on behalf of the Depository, in accordance with its customary procedures. Any physical bond issued in exchange for an interest in a Global Bond will be 

 
effected through the DTC’s Deposit/Withdrawal at Custodian system and an appropriate adjustment will be made in the records of the Securities Custodian
to reflect a decrease in the principal amount of the relevant Global Bond. 
 Any physical bond delivered in exchange for an interest in a
Global Bond shall bear the applicable legend regarding transfer restrictions applicable to such physical bond. 
 Transfer and Exchange. (a) The
following provisions shall apply with respect to any proposed transfer of a beneficial interest in a Rule 144A Global Bond or a physical bond issued in exchange therefor prior to the date which is one year (or such period as may be required or
permitted by any subsequent change in applicable law) after the later of the date of its original issue and the last date on which the Company or any affiliate of the Company was the owner of such Bond (or any predecessor thereto) (the “U.S.
Resale Restriction Termination Date”): 
 (i) a transfer of a beneficial interest in a Rule 144A Global Bond or a physical bond
issued in exchange therefor to a QIB shall be made upon the representation of the transferee in the form as set forth on the reverse of the Bond that it is purchasing for its own account or an account with respect to which it exercises sole
investment discretion and that it and any such account is a “qualified institutional buyer” within the meaning of Rule 144A, and is aware that the sale to it is being made in reliance on Rule 144A and acknowledges that it has received such
information regarding the Company as the undersigned has requested pursuant to Rule 144A or has determined not to request such information and that it is aware that the transferor is relying upon its foregoing representations in order to claim the
exemption from registration provided by Rule 144A; 
 (ii) a transfer of a beneficial interest in a Rule 144A Global Bond or a physical bond
issued in exchange therefor to a Non-U.S. Person shall be made upon receipt by the Corporate Trustee or its agent of a certificate substantially in the form set forth in Exhibit D from the proposed transferee and, if requested by the Company or the
Corporate Trustee, the delivery of an opinion of counsel, certification and/or other information satisfactory to each of them. 
 After the
U.S. Resale Restriction Termination Date, interests in the Rule 144A Global Bond may be transferred without requiring any additional certification. 
 (b) The following provisions shall apply with respect to any proposed transfer of a Regulation S Temporary Global Bond prior to the expiration of the Restricted Period: 
 (i) a transfer of a Regulation S Temporary Global Bond or a beneficial interest therein to a QIB shall be made upon the representation of the transferee,
in the form of certificate attached as Exhibit B hereto, that it is purchasing the Bond for its own account or an account with respect to which it exercises sole investment discretion and that it and any such account is a “qualified
institutional buyer” within the meaning of Rule 144A, and is aware that the sale to it is being made in reliance on Rule 144A and acknowledges that it has received such information regarding the Company as the undersigned has requested pursuant
to Rule 144A or has determined not to request such information and that it is aware that the transferor is relying upon its foregoing representations in order to claim exemption from registration provided by Rule 144A; and 

 (ii) a transfer of a Regulation S Temporary Global Bond or a beneficial interest therein to a Non-U. S.
Person shall be made upon receipt by the Corporate Trustee or its agent of a certificate substantially in the form set forth in Exhibit D hereof from the proposed transferee and, if requested by the Company or the Corporate Trustee, receipt by the
Corporate Trustee or its agent of an opinion of counsel, certification and/or other information satisfactory to each of them. 
 After the
expiration of the Restricted Period, interests in the Regulation S Global Bond may be transferred without requiring certification set forth in Exhibit D or any additional certification. 
 (c) Restricted Securities Legend. Upon the transfer, exchange or replacement of the Bonds not bearing a Restricted Securities Legend, the Security
Registrar shall deliver Bonds that do not bear a Restricted Securities Legend. Upon the transfer, exchange or replacement of the Bonds bearing a Restricted Securities Legend, the Bond Registrar shall deliver only Bonds that bear a Restricted
Securities Legend unless there is delivered to the Bond Registrar an opinion of counsel to the effect that neither such legend nor the related restrictions on transfer are required in order to maintain compliance with the provisions of the
Securities Act. 
 The Bond Registrar shall retain copies of all letters, notices and other written communications received pursuant to
Section 6. The Company shall have the right to inspect and make copies of all such letters, notices or other written communications at any reasonable time upon the giving of reasonable prior written notice to the Bond Registrar. 
 SECTION 7. The Company may deliver to the Corporate Trustee in substitution for any Bonds of the Sixtieth Series, mortgage bonds or
other similar instruments of the Company or any successor entity, whether by merger, combination or acquisition of all or substantially all of the assets of the Company, or otherwise, issued under a mortgage and deed of trust or similar instrument
of the Company or any successor entity in like principal amount of like term and bearing the same rate of interest as the Bonds of the Sixtieth Series (such substituted bonds hereinafter being referred to as the “Substituted Mortgage
Bonds”). The Substituted Mortgage Bonds may only be delivered to the Corporate Trustee (A) upon execution and delivery of a mortgage and deed of trust or similar instrument which, among other things, contains requirements (i) for
the delivery of net earnings certificates, on terms and conditions and in circumstances consistent with the requirements of the Mortgage (except that the ratio of two and one-half (2 1/2) times contained in Section 27 of the Mortgage may be replaced with a
ratio of two (2) times), (ii) that the principal amount of bonds authenticated on the basis of property additions not exceed 70% of the lesser of cost or fair market value thereof, (iii) that property and cash be released from the
lien of such instrument upon terms and conditions consistent with the requirements of the Mortgage, (iv) that the Company provide for maintenance and repair expenditures in a manner substantially consistent with Section 38 of the Mortgage
and (v) that bonds may be accelerated by the holders of 25% of the aggregate principal amount of all bonds outstanding under such instrument, and (B) upon receipt by the Corporate Trustee of (i) ratings, at the Company’s expense,
of the original bonds from both Moody’s and S&P (as hereinafter defined), to the extent the original bonds were not so rated, such ratings not giving effect to any downgrade following the announcement of any transaction related to or

 KANSAS GAS AND ELECTRIC COMPANY, a corporation of the State of Kansas (hereinafter called the “Company”), for

or currency from the date of issuance at the rate of 6.70% per annum, payable beginning on December 15, 2009 semi-annually on June 15 and December 15 of each year until maturity or if this Bond shall be duly called for redemption
until the redemption date. If an interest payment date or a redemption date falls on a day that is not a business day, such interest payment date or redemption date, as the case may be, shall be the immediately succeeding business day with the same
force and effect as if made on the original interest payment date or redemption date, as the case may be, and no interest shall accrue for the period from and after such original interest payment date or redemption date, as the case may be. The
principal of and interest on this bond shall be payable at the office or agency of the Company in the Borough of Manhattan, The City of New York, except as follows. Payments in respect of the bonds represented by Global Bonds (as defined in the

 A-1 

 
made by wire transfer of immediately available funds to the accounts specified by The Depository Trust Company. Payments of interest in respect of physical
bonds will be made by mailing a check to the registered address of each Holder thereof; provided, however, that payments on a physical bond will be made by wire transfer to a U.S. Dollar account maintained by the payee with a bank
in the United States if such holder certifies to the Company that it is a holder of Bonds of the Sixtieth Series (as defined below) in an aggregate principal amount equal to or greater than $10,000,000 and elects payment by wire transfer by giving
written notice to the Corporate Trustee (as defined below) to such effect designating such account no later than 30 days immediately preceding the relevant due date for payment (or such other date as the Corporate Trustee may accept in its
discretion). 
 This bond is one of an issue of bonds of the Company issuable in series and is one of a series known as its First Mortgage Bonds, 6.70%
Series due 2019, (referred to herein as “Bonds of the Sixtieth Series”), the Bonds of this series being limited to THREE HUNDRED MILLION DOLLARS ($300,000,000) in aggregate principal amount at any one time outstanding, all bonds of
all series issued and to be issued under and equally secured (except in so far as any sinking or other fund, established in accordance with the provisions of the Mortgage hereinafter mentioned, may afford additional security for the bonds of any
particular series and except that bonds representing future advances, if any, in excess of the maximum amount of future advances permitted to be secured by the chattel mortgage created by the Mortgage, may not be secured by such chattel mortgage
equally with bonds theretofore issued) by a Mortgage and Deed of Trust, together with any indenture supplemental thereto (including the Fifty-fourth Supplemental Indenture, dated as of June 11, 2009 (the “Supplemental
Indenture”)), dated as of April 1, 1940 (the “Mortgage”), executed by the Company to The Bank of New York Mellon Trust Company, N.A. (as successor to BNY Midwest Trust Company) (the “Corporate
Trustee”) and Judith L. Bartolini (the “Individual Trustee,” together with the Corporate Trustee, the “Trustees”). Reference is made to the Mortgage for a description of the property mortgaged and pledged, the
nature and extent of the security, the rights of the holders of the bonds and of the Trustees in respect thereof, the duties and immunities of the Trustees and the terms and conditions upon which the bonds are and are to be secured and the
circumstances under which additional bonds may be issued and the definitions of terms not otherwise defined herein. With the consent of the Company and to the extent permitted by and as provided in the Mortgage, the rights and obligations of the
Company and/or the rights of the holders of the bonds and/or coupons and/or the terms and provisions of the Mortgage may be modified or altered by affirmative vote of the holders of at least sixty per centum (60%) in principal amount of the
bonds then outstanding under the Mortgage and, if the rights of one or more, but less than all, series of bonds then outstanding are to be affected, then also by affirmative vote of the holders of at least sixty per centum (60%) in principal
amount of the bonds then outstanding of the series of bonds so to be affected (excluding in any case bonds disqualified from voting by reason of the Company’s interest therein as provided in the Mortgage); provided that, without the
consent of the holder hereof, no such modification or alteration shall impair or affect the right of the holder to receive payment of the principal of and interest on this bond, on or after the respective due 

  

 A-2 

 
dates expressed herein, or permit the creation of any lien equal or prior to the lien of the Mortgage, deprive the holder of a lien on the mortgaged and
pledged property or permit the reduction of the percentages required for modification. 
 The principal hereof may be declared or may become due prior to the
maturity date hereinbefore named on the conditions, in the manner and at the time set forth in the Mortgage, upon the occurrence of a default as in the Mortgage provided. 
 Subject to Sections 4, 5 and 6 of Article I of the Supplemental Indenture, at the option of the registered owner, any Bonds of the Sixtieth Series, upon surrender thereof, for cancellation, at the office or
agency of the Company in the Borough of Manhattan, City of New York, shall be exchangeable for a like aggregate principal amount of bonds of the same series of other authorized denominations. The Bonds of the Sixtieth Series may bear such legends as
may be necessary to comply with any law or with any rules or regulations made pursuant thereto or with the rules or regulations of any stock exchange or to conform to usage with respect thereto. 
 Subject to Sections 4, 5 and 6 of Article I of the Supplemental Indenture, Bonds of the Sixtieth Series shall be transferable upon the surrender thereof, for
cancellation together with a written instrument of transfer in form approved by the registrar duly executed by the registered owner or by his duly authorized attorney, at the office or agency of the Company in the Borough of Manhattan, City of New
York. 
 The bonds of this series are subject to redemption as provided in the Supplemental Indenture. 
 No recourse shall be had for the payment of the principal of, redemption premium, if any, or interest on this bond against any incorporator or any past, present or
future subscriber to the capital stock, stockholder, officer or director of the Company or of any predecessor or successor corporation, as such, either directly or through the Company or any predecessor or successor corporation under any rule of
law, statute or constitution or by the enforcement of any assessment or otherwise, all such liability of incorporators, subscribers, stockholders, officers and directors being released by the holder or owner hereof by the acceptance of this bond and
being likewise waived and released by the terms of the Mortgage. 
 This bond shall not become obligatory until The Bank of New York Mellon Trust Company,
N.A., the Corporate Trustee under the Mortgage, or its successor thereunder, shall have signed the form of certificate endorsed hereon.
