Indenture shall be designated as “First Mortgage Bonds, 5.10% Series Due 2020” of the Company. The Bonds of the 2020 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 2020 Series shall mature July 15, 2020 and shall bear interest at the rate of five and ten one-hundredths percent (5.10%) per annum
payable semi-annually on the fifteenth day of January and July in each year, commencing January 15, 2006. Every Bond of the 2020 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 2020 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 2020 Series interest shall be in default on any Bonds of the 2020 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 2020 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 2020 Series shall bear interest from the January 15, or July 15, next preceding the date thereof, unless such Bond shall be dated prior to

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 such defaulted interest. The term “record date” as
used in this Section with regard to any January 15 interest payment date shall mean the close of business on the next preceding January 1 and with regard to any July 15 interest payment date shall mean the close of business on the next preceding
July 1, or if such day is not a business day, the business

 prior to January 15, 2006, in which case from June 30, 2005, at the rate of five and ten one-hundredths percent (5.10%)
per annum, payable semiannually, on the fifteenth days of January and July in each year, commencing January 15, 2006, 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 January 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 January 1 and with respect
to any July 15 interest payment date shall mean the close of business on the next preceding July 1, 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

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, executed by the Company to BNY Midwest Trust Company (herein called the “Trustee”), as
Trustee (as successor to Harris Trust and Savings Bank), as amended by the indentures supplemental thereto including the Thirty-Ninth indenture supplemental thereto dated as of June 30, 2005 (herein called the “Supplemental
Indenture”), between the Company and the Trustee (said Mortgage and Deed of Trust, 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, 5.10% Series Due 2020” (herein called “Bonds of the 2020 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 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 Indenture. 
  
 This Bond is subject to redemption at any time and from time to time prior to maturity at the option of the Company at a price determined 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 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 2020 Series, mortgage bonds or other similar instruments
as set forth in the Indenture. 
  

 -11- 

 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 BNY Midwest Trust Company, 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. 
  
 IN
WITNESS WHEREOF, WESTAR ENERGY, INC. has caused this Bond to be signed in its name by its Chairman of the Board, President and Chief Executive Officer or a Vice President, manually or by facsimile, and its corporate seal (or a facsimile thereof) to

the 2020 Series, after giving the required notice under subsection (2) of this Article III, Section 1, at a redemption price equal to the greater of:

 plus, in either case, accrued and unpaid
interest, if any, to the redemption date (subject to the right of holders of record on the relevant record date to receive interest due on the relevant interest payment date). 
  
 The “Treasury Rate” will be determined on the third business day preceding the redemption date and means, with
respect to any redemption date: 
  
 (1) the yield, under the
heading which represents the average for the immediately preceding week, appearing in the most recently published statistical release published by the Board of Governors of the Federal Reserve System designated as “Statistical Release
H.15(519)” or any successor publication which is published weekly by the Board of Governors of the Federal Reserve System and which establishes yields on actively traded United States Treasury securities adjusted to constant maturity under the
caption “Treasury Constant Maturities,” for the maturity corresponding to the Comparable Treasury Issue (if no maturity is within three months before or after (x) in the case of the Bonds of the 2020 Series, the Remaining Life or (y) in
the case of the Bonds of the 2036 Series, July 15, 2015, yields for the two published maturities most closely corresponding to the Comparable Treasury Issue will be determined and the Treasury Rate will be interpolated or extrapolated from those
yields on a straight-line basis, rounding to the nearest month), or 
  
 (2) if such release (or any successor release) is not published during the week preceding the calculation date or does not contain those yields, the rate per annum equal to the semi-annual equivalent yield to maturity of the Comparable
Treasury Issue, calculated using 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. 
  
 “Comparable Treasury Issue” means the United States Treasury
security selected by the Independent Investment Banker as having a maturity comparable (x) in the case of the Bonds of the 2020 Series, to the remaining term, referred to as the Remaining Life, of the 2020 Series Bonds to be redeemed or (y) in the
case of the 2036 Series Bonds, to July 15, 2015, that would be utilized, 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 Life,
in the case of the 2020 Series Bonds, or to July 15, 2015, in the case of the 2036 Series Bonds. 
  
 “Comparable Treasury Price” means (1) the average of three Reference Treasury Dealer Quotations for that redemption date, or (2) if the
Independent Investment Banker is unable to obtain three Reference Treasury Dealer Quotations, the average of all quotations obtained. 
  
 “Independent Investment Banker” means an independent investment banking or commercial banking institution of national standing appointed by the
Company. 
  

 -14- 

 “Reference Treasury Dealer” means (1) any independent investment banking or commercial banking
institution of national standing appointed by the Company and any of its successors, provided, however, that if any of the foregoing shall cease to be a primary U.S. Government securities dealer in The City of New York, referred to as a Primary
Treasury Dealer, the Company shall substitute therefor another Primary Treasury Dealer, and (2) any other Primary Treasury Dealer selected by the Independent Investment Banker and approved in writing 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 Independent Investment Banker, 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 Independent Investment Banker at 3:30 p.m., New York City time, on the third business day preceding 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 2020 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 2020 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 2020 Series or pay the holders thereof any redemption proceeds and the
Company’s failure to so redeem the Bonds of the 2020 Series will not be considered a default or event of default under the Indenture. 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 2020 Series will not be redeemed. 
  
 SECTION 2. The Company may deliver to the Trustee in substitution for any Bonds of the 2020 Series, mortgage bonds or other
similar secured 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 and having the same interest payment dates and same redemption provisions as the Bonds of the 2020 Series and which are otherwise
substantially similar to the Bonds of the 2020 Series (such substituted bonds hereinafter being referred to in this Article III, Section 2 as the “2020 Series Substituted Mortgage Bonds”). The 2020 Series Substituted Mortgage Bonds
may only be delivered to the Trustee upon receipt by the Trustee of (i) a letter from Moody’s (as hereinafter defined), dated within ten days prior to the date of delivery of the 2020 Series Substituted Mortgage Bonds, stating that its rating
of the 2020 Series Substituted Mortgage Bonds is at least equal to its then current rating on the Bonds of the 2020 Series, (ii) a letter from S&P (as hereinafter defined), dated within ten days prior to the date 
  

 -15-

Mortgage Bonds is at least equal to its then current rating on the Bonds of the 2020 Series, (iii) an opinion of counsel, which may be counsel to the Company or any successor entity, that such substitution will not result in the recognition of
capital gain or loss for U.S. federal income tax purposes to the holders of the Bonds of the 2020 Series, (iv) an opinion of counsel which may be counsel to the Company or any successor entity, to the effect that the 2020 Series Substituted Mortgage
Bonds shall have been duly and validly authorized, executed, authenticated, and delivered and shall constitute the valid, legally binding and enforceable obligations of the Company or any successor entity 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

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, 5.875% Series Due 2036” (herein called “Bonds of the 2036 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 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 Indenture. 
  
 This Bond is subject to redemption at any time and from time to time prior to maturity at the option of the Company at a price determined 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 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 2036 Series, mortgage bonds or other similar instruments
as set forth in the Indenture. 
  

 -20- 

 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 BNY Midwest Trust Company, 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. 
  
 IN
WITNESS WHEREOF, WESTAR ENERGY, INC. has caused this Bond to be signed in its name by its Chairman of the Board, President and Chief Executive Officer or a Vice President, manually or by facsimile, and its corporate seal (or a facsimile thereof) to
be hereto affixed and attested by its Secretary or an Assistant Secretary, manually or by facsimile.

Section 9 of Article II of the Original Indenture. 
  
 ARTICLE V

  
 ISSUE OF BONDS OF THE 2036 SERIES 
  
 SECTION 1. The total principal amount of Bonds of the 2036 Series which may
be authenticated and delivered hereunder is not limited except as the Original Indenture and this Supplemental Indenture limit the principal amount of Bonds which may be issued thereunder. 
  
 SECTION 2. Bonds of the 2036 Series for the aggregate principal amount of
$150,000,000 may forthwith be executed by the Company and delivered to the Trustee and shall be authenticated by the Trustee and delivered (either before or after the filing or recording hereof) to or upon the order of the Company, upon receipt by

 ARTICLE VI 
  
 REDEMPTION AND SUBSTITUTION OF BONDS OF THE 2036 SERIES 
  
 SECTION 1. 
  
 (1) Optional Redemption of Bonds of the 2036 Series. At any time, and from time to time, the Company may redeem all or any portion of the Bonds of
the 2036 Series, after giving the required notice under subsection (2) of this Article VI, Section 1, at a redemption price equal to: 
  
 (a) if the redemption date is prior to July 15, 2015, the greater of (i) 100% of the principal amount of the Bonds of the 2036 Series to
be redeemed or (ii) the sum of the present values of the remaining scheduled payments of the principal amount of the Bonds of the 2036 
  

 -22- 

 Series to be redeemed and interest thereon (exclusive of interest to the redemption date) discounted to
the date of redemption on a semi-annual basis (assuming a 360-day year consisting of twelve 30-day months) at the Treasury Rate plus 35 basis points; for purposes of the foregoing computation, the Bonds of the 2036 Series shall be treated as if they
mature on, and the last payment of interest was made on, July 15, 2015; or 
  
 (b) if the redemption date is on or after July 15, 2015, 100% of the principal amount of the Bonds of the 2036 Series to be redeemed, 
  
 plus, in either case, accrued and unpaid interest, if any, to the redemption date (subject to the right of holders of record on the relevant
record date to receive interest due on the relevant interest payment date). 
  
 The “Treasury Rate” will be determined on the third business day preceding the redemption date and means, with respect to any redemption date: 
  
 (1) the yield, under the heading which represents the average for the immediately preceding week, appearing in the most
recently published statistical release published by the Board of Governors of the Federal Reserve System designated as “Statistical Release H.15(519)” or any successor publication which is published weekly by the Board of Governors of the
Federal Reserve System and which establishes yields on actively traded United States Treasury securities adjusted to constant maturity under the caption “Treasury Constant Maturities,” for the maturity corresponding to the Comparable
Treasury Issue (if no maturity is within three months before or after the Remaining Life, yields for the two published maturities most closely corresponding to the Comparable Treasury Issue will be determined and the Treasury Rate will be
interpolated or extrapolated from those yields on a straight-line basis, rounding to the nearest month), or 
  
 (2) if such release (or any successor release) is not published during the week preceding the calculation date or does not contain those yields, the rate
per annum equal to the semi-annual equivalent yield to maturity of the Comparable Treasury Issue, calculated using 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. 
  
 “Comparable Treasury Issue”
means, in the case of the Bonds of the 2036 Series, the United States Treasury security selected by the Independent Investment Banker as having a maturity comparable to July 15, 2015, that would be utilized, at the time of selection and in
accordance with customary financial practice, in pricing new issues of corporate debt securities of comparable maturity to July 15, 2015. 
  
 “Comparable Treasury Price” means (1) the average of three Reference Treasury Dealer Quotations for that redemption date, or (2) if the
Independent Investment Banker is unable to obtain three Reference Treasury Dealer Quotations, the average of all quotations obtained. 
  
 “Independent Investment Banker” means an independent investment banking or commercial banking institution of national standing appointed by the
Company. 
  

 -23- 

 “Reference Treasury Dealer” means (1) any independent investment banking or commercial banking
institution of national standing appointed by the Company and any of its successors, provided, however, that if any of the foregoing shall cease to be a primary U.S. Government securities dealer in The City of New York, referred to as a Primary
Treasury Dealer, the Company shall substitute therefor another Primary Treasury Dealer, and (2) any other Primary Treasury Dealer selected by the Independent Investment Banker and approved in writing 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 Independent Investment Banker, 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 Independent Investment Banker at 3:30 p.m., New York City time, on the third business day preceding 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 2036 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 2036 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 2036 Series or pay the holders thereof any redemption proceeds and the
Company’s failure to so redeem the Bonds of the 2036 Series will not be considered a default or event of default under the Indenture. 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 2036 Series will not be redeemed. 
  
 SECTION 2. The Company may deliver to the Trustee in substitution for any Bonds of the 2036 Series, mortgage bonds or other
similar secured 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 and having the same interest payment dates and same redemption provisions as the Bonds of the 2036 Series and which are otherwise
substantially similar to the Bonds of the 2036 Series (such substituted bonds hereinafter being referred to in this Article VI, Section 2 as the “2036 Series Substituted Mortgage Bonds”). The 2036 Series Substituted Mortgage Bonds
may only be delivered to the Trustee upon receipt by the Trustee of (i) a letter from Moody’s (as hereinafter defined), dated within ten days prior to the date 
  

 -24- 

 of delivery of the 2036 Series Substituted Mortgage Bonds, stating that its rating of the 2036 Series Substituted
Mortgage Bonds is at least equal to its then current rating on the Bonds of the 2036 Series, (ii) a letter from S&P (as hereinafter defined), dated within ten days prior to the date of delivery of the 2036 Series Substituted Mortgage Bonds,
stating that its rating to the 2036 Series Substituted Mortgage Bonds is at least equal to its then current rating on the Bonds of the 2036 Series (iii) an opinion of counsel, which may be counsel to the Company or any successor entity, that such
substitution will not result in the recognition of capital gain or loss for U.S. federal income tax purposes to the holders of the Bonds of the 2036 Series, (iv) an opinion of counsel which may be counsel to the Company or any successor entity, to
the effect that the 2036 Series Substituted Mortgage Bonds shall have been duly and validly authorized, executed, authenticated, and delivered and shall constitute the valid, legally binding and enforceable obligations of the Company or any
successor entity 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 (v) such other certificates and documents with respect to the issuance and delivery of the 2036 Series Substituted Mortgage Bonds as may be
required by law or as the Trustee may reasonably request.

 The Company hereby covenants, warrants and agrees:

  
 SECTION 1. That the Company is lawfully seized and possessed
of all of the mortgaged property described in the granting clauses of this Supplemental Indenture; that it has good, right and lawful authority to mortgage the same as provided in this Supplemental Indenture; and that such mortgaged property is, at
the actual date of the initial issue of the Bonds of the 2020 Series and the Bonds of the 2036 Series, free and clear of any deed of trust, mortgage, lien, charge or encumbrance thereon or affecting the title thereto prior to the Indenture, except

Indenture, the Company will, at any time or from time to time within six months after the date of such release, retire Bonds outstanding under the Original Indenture in an aggregate principal amount equal to the fair value of the electric properties
so released pursuant to Section 3 of Article VII of the Original Indenture, as stated in the engineer’s certificate required by Section 3(b) of said Article VII, and the proceeds of the electric properties so released pursuant to Section 5 of
said Article VII. Such retirement of Bonds shall be effected in either one or both of the following methods: 
  
 (a) By the withdrawal pursuant to Section 2 of Article VIII of the Original Indenture of any moneys deposited with the Trustee pursuant to
Sections 3(d), 4(d) and 5 of Article VII of the Original Indenture upon such release; or

total principal amount of all Bonds then outstanding.

RIGHTS TO AMEND THE ORIGINAL INDENTURE 
  
 SECTION 1. So long
as any of the Bonds of any series originally issued prior to January 1, 1997 shall remain outstanding:

 (d) Subsection (a) of Section 14, clauses (1) and (2) of Subsection (a) of Section 16 of
Article IV and clause (1) of Subsection (b) of Section 1 of Article XII of the Original Indenture shall be deemed amended by substituting the words “sixty percent (60%)” for “seventy percent (70%)” where they appear in said
provisions of the Original Indenture. 
  
 (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 (i) net non-operating income, (ii) net
earnings from mortgaged property other than property of the character of property additions and (iii) 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 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 

  

 -28-

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.

  

	 	(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. All of the Bonds of the 2020 Series and all of the Bonds of the 2036 Series and of any series initially issued
after the initial issuance of Bonds of the 2020 Series and the Bonds of the 2036 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.

initially issued after the initial issuance of Bonds of the 2020 Series or the Bonds of the 2036 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. 
  

 -29- 

 SECTION 3. The Company reserves the right subject to appropriate corporate action, but without the
consent or other action of holders of bonds of any series created after January 1, 1997, to make such amendments to the Original Indenture, as supplemented, as shall be necessary in order to amend Article VII thereof by adding thereto a Section 8
and a Section 9 to read as follows: 
  
 “SECTION 8. Notwithstanding any other provision of this Indenture, unless an event of default shall have happened and be continuing, or shall happen as a result of the making or granting of an application to release mortgaged property
permitted by this Section 8, the Trustee shall release from the lien of this Indenture any mortgaged property if the fair value to the Company of all of the property constituting the trust estate (excluding the mortgaged property to be released but
including any mortgaged property to be acquired by the Company with the proceeds of, or otherwise in connection with, such release) equals or exceeds an amount equal to 10/7ths of the aggregate principal amount of outstanding Bonds and prior lien
bonds outstanding at the time of such release, upon receipt by the Trustee of: 
  
 “(a) an officers’ certificate dated the date of such release, requesting such release, describing in reasonable detail the
mortgaged property to be released and stating the reason for such release; 
  
 “(b) an engineer’s certificate, dated the date of such release, stating (i) that the signer of such engineer’s certificate has examined such officers’ certificate in connection with such release,
(ii) the fair value to the Company, in the opinion of the signer of such engineer’s certificate, of (A) all of the property constituting the trust estate, and (B) the mortgaged property to be released, in each case as of a date not more than 90
days prior to the date of such release, and (iii) that in the opinion of such signer, such release will not impair the security under this Indenture in contravention of the provisions hereof; 
  
 “(c) in case any bondable property is being acquired by
the Company with the proceeds of, or otherwise in connection with, such release, an engineer’s certificate, dated the date of such release, as to the fair value to the Company, as of the date not more than 90 days prior to the date of such

 Exhibit 10.1 
  
 EMPLOYMENT AGREEMENT 
  
 This Employment Agreement (this “Agreement”) is entered into as of June 27, 2005, between FATS, Inc., a Delaware corporation (the
“Company”) and Ronavan R. Mohling (the “Executive”). 
  
 WHEREAS, the Company is the operating subsidiary of Firearms Training Systems, Inc. (the “Parent”), a leading worldwide provider of small and supporting arms training simulators; and 
  
 WHEREAS, the Company desires to employ the Executive to serve as
Chairman and Chief Executive Officer of the Company, and the Executive desires to be employed by the Company, upon the terms and subject to the conditions set forth herein. 
  
 NOW, THEREFORE, in consideration of the premises and the mutual agreements contained herein, the Company and the
Executive hereby agree as follows: 
  
 1. Employment.
The Company hereby agrees to employ the Executive and the Executive hereby agrees to be employed by the Company upon the terms and subject to the conditions contained in this Agreement. The term of employment of the Executive by the Company
pursuant to this Agreement (the “Employment Period”) shall commence on June 27, 2005 (the “Effective Date”) and shall end on the third anniversary of the Effective Date, unless earlier terminated pursuant to
Section 4 hereof. 
  
 2. Position and Duties;
Responsibilities. (a) Position and Duties. The Company shall employ the Executive during the Employment Period as its Chairman and Chief Executive Officer, with the titles of Chairman and Chief Executive Officer. The Executive shall
report directly to the Board of Directors of the Parent. During the Employment Period, the Executive shall perform faithfully and loyally and to the best of the Executive’s abilities the duties assigned to the Executive hereunder and shall
devote the Executive’s full business time, attention and effort to the affairs of the Company and its subsidiaries, and shall use the Executive’s best efforts to promote the interests of the Company, its subsidiaries and the Parent. The
Executive may engage in charitable, civic or community activities and, with the prior approval of the Board of Directors, may serve as a director of any other business corporation, provided that such activities or service do not interfere with the
Executive’s duties hereunder or violate the terms of any of the covenants contained in Sections 6, 7, 8, 9 or 10 hereof. 
  
 (b) Responsibilities. Subject to the powers, authority and responsibilities vested in the Board and in duly constituted committees of the Board,
the Executive shall have the authority and responsibility for the Company’s management. The Executive shall also perform such other duties (not inconsistent with the position of Chairman and Chief Executive Officer) on behalf of the Company and
its subsidiaries as may from time to time be authorized or directed by the Board of Directors. 

 3. Compensation. (a) Base Salary. During the Employment Period, the Company shall
pay to the Executive a base salary at the rate of $325,000.00 per annum (“Base Salary”), payable in accordance with the Company’s executive payroll policy. Such Base Salary shall be reviewed annually and shall be subject to such
changes as determined by the Compensation Committee of the Board (the “Compensation Committee”). 
  
 (b) Annual Bonus. During the Employment Period, the Company shall provide the Executive the opportunity to earn an annual merit-based bonus of up
to fifty percent (50%) of this Base Salary, based upon the Company’s performance, the Executive’s individual performance and the Company prospects and liquidity position (the “Annual Bonus”). The actual amount of such Annual
Bonus shall be determined by the Board after the end of the Company’s fiscal year, in its sole discretion; provided, however, that in no event may the Executive receive an Annual Bonus in excess of fifty percent (50%) of the
Executive’s Base Salary. In addition, in the event of a Sale of the Parent (defined as the acquisition of fifty-one percent (51%) or more of the Parent’s common stock outstanding by a single party), Executive will be entitled to receive
the maximum Annual Bonus of fifty percent (50%) of his Base Salary for the fiscal year in which the Sale of the Parent takes place as long as he remains employed by the Company through the end of that fiscal year or is terminated by the Company
other than for Cause. Payment of the Annual Bonus in such circumstances will not reduce any payments to which the Executive is entitled pursuant to Section 4 of this Agreement. 
  
 (c) Stock Options. In his prior Employment Agreement dated August 9, 2002, the Executive received a grant of
non-qualified stock options under the Firearms Training System, Inc. Stock Option Plan as follows: 
  
 (i) The Executive was granted an option to purchase from the Parent 2,100,000 of the company’s common shares currently outstanding.
The options bear a strike price of $0.40 per share. 
  
 (ii) After January 1, 2004, the options vest in equal twenty percent (20%) portions on an annual basis over a five (5) year waiting period commencing on January 1, 2004 (i.e., the first vesting date was January 1, 2005 and the final vesting
date is January 1, 2009). Other vesting terms and conditions will be substantially similar to those contained in the Company’s existing option grants, including becoming 100% vested and exercisable upon the Sale of the Parent. 
  
 (d) Other Benefits. During the Employment Period, the Executive shall
be entitled to participate in the Company’s employee benefit plans that are generally available from time to time to executives of the Company, including group medical, dental, life, accidental death and dismemberment, short-term disability,
long-term disability, business travel accident plans, sick leave, vacation, and the profit sharing retirement plan (all such benefits being hereinafter referred to as the “Employee Benefits”). 
  
 (e) Expense Reimbursement. During the Employment Period, the Company
shall reimburse the Executive, in accordance with the Company’s policies and procedures, for all proper documented expenses incurred by the Executive in the performance of the Executive’s duties hereunder. 
  

 2 

 4. Termination. (a) Death. Upon the death of the Executive, this Agreement shall
automatically terminate and all rights of the Executive and the Executive’s heirs, executors and administrators to compensation and other benefits under this Agreement shall cease immediately, except that the Executive’s heirs, executors
or administrators, as the case may be, shall be entitled to: 
  
 (i) accrued Base Salary through and including the Executive’s date of death; 
  
 (ii) the Annual Bonus, if any, that the Executive would have received for the fiscal year in which his death occurs had he remained
employed through the end of such year, reduced pro rata for that portion of such fiscal year not completed by the Executive and payable at such time as the Executive would have received such Annual Bonus had he remained employed through the end of
such fiscal year; and 
  
 (iii) other Employee
Benefits to which the Executive was entitled on the date of death in accordance with the terms of the plans and programs of the Company. 
  
 (b) Disability. The Company may, at its option, terminate this Agreement upon written notice to the Executive if the Executive, because of physical
or mental incapacity or disability, fails to perform the essential functions of the Executive’s position, with or without reasonable accommodation, required of the Executive hereunder for a continuous period of one hundred twenty (120) days or
any one hundred eighty (180) days within any twelve (12) month period. In the event of any dispute regarding the existence of the Executive’s incapacity or disability hereunder, the matter shall be resolved by the determination of a physician,
qualified to practice medicine in the state of the Executive’s Residence, to be selected by the Board. The Executive shall have the right to require a second opinion from a physician qualified to practice medicine in the state of the
Executive’s residence, as selected by the Executive. If the initial and second opinions are inconsistent, the matter shall be resolved by a third opinion from a physician licensed to practice medicine as selected by the agreement between the
Company and the Executive. Upon such termination, all obligations of the Company hereunder shall cease immediately, except that the Executive shall be entitled to: 
  
 (i) accrued Base Salary through and including the effective date of the Executive’s termination of
employment; 
  
 (ii) the Annual Bonus, if any,
that the Executive would have received for the fiscal year in which the Executive’s termination of employment occurs had he remained employed through the end of such year, reduced pro rata for that portion of such fiscal year not completed by
the Executive and payable at such time as the Executive would have received such Annual Bonus had he remained employed through the end of such fiscal year; and 
  

(iii) other Employee Benefits to which the Executive is entitled upon termination of employment in accordance with the terms of the
plans and programs of the Company. 
  
 (c)
Cause. (i) The Company may, at its option, terminate the Executive’s employment under this Agreement for Cause (as hereinafter defined) upon written notice 
  

 3 

 to the Executive (the “Cause Notice”). Any such termination for Cause shall be authorized by
the Board. The Cause Notice shall state the particular action(s) or inaction(s) giving rise to termination for Cause. 
  
 (ii) As used in this Agreement, the term “Cause” shall mean any one or more of the following: 
  
 (A) The Executive’s commission of a felony or any other
crime involving moral turpitude, fraud, misrepresentation, embezzlement, or theft, 
  
 (B) The Executive’s engaging in any other activity that is harmful (including alcoholic or other self-induced affliction), in a
material respect, to the Company, any of its subsidiaries or the Parent, monetarily or otherwise, as determined by a majority of the Board; 
  
 (C) The Executive’s material malfeasance (including, without limitation, any intentional act of fraud or theft), misconduct, or gross
negligence in connection with the performance of his duties hereunder; 
  
 (D) The Executive’s significant violation of any statutory or common law duty of loyalty to the Company, any of its subsidiaries or the Parent; 
  
 (E) The Executive’s material breach of this Agreement or of a material policy of the Company or the
Parent (including, without limitation, disclosure or misuse of any confidential or competitively sensitive information or trade secrets of the Company, any of its subsidiaries or the Parent); 
  
 (F) The Executive’s refusal or failure to carry out
directives or instructions of the majority of the Board that are consistent with the scope and nature of the Executive’s duties and responsibilities set forth herein; or 
  
 (G) Any breach by the Executive of any one or more of the covenants contained in Section 6, 7, 8, 9 or 10
hereof. 
  
 (iii) With respect to E and F above,
the Executive shall have ten days after the Cause Notice is given to cure the particular action(s) or inaction(s), to the extent a cure is possible. If the Executive so effects a cure to the satisfaction of the Board, the Cause Notice shall be
deemed rescinded and of no force or effect. 
  
 (iv) The exercise of the right of the Company to terminate this Agreement pursuant to this Section 4(c) shall not abrogate the rights or remedies of the Company in respect of the breach giving rise to such termination. 
  
 (v) If the Company terminates the Executive’s
employment for Cause, all obligations of the Company hereunder shall cease, except that the Executive shall be entitled to the payments and benefits specified in Sections 4(b)(i) and 4(b)(iii) hereof. 
  

 4 

 (d) Termination Without Cause. The Company may, at its option, terminate the Executive’s
employment under this Agreement upon written notice to the Executive for a reason other than a reason set forth in Section 4(a), 4(b) or 4(c). Any such termination shall be authorized by the Board. If the Company terminates the Executive’s
employment for any such reason, all obligations of the Company hereunder shall cease immediately, except that the Executive shall be entitled to: 
  
 (i) accrued Base Salary through and including the date of the Executive’s termination of employment; 
  
 (ii) other Employee Benefits to which the Executive is
entitled upon termination of employment in accordance with the terms of the plans and programs of the Company; and 
  
 (iii) an amount equal to the Executive’s Annual Base Salary as in effect immediately prior to the Executive’s termination of
employment, payable in twelve (12) equal monthly installments following the Executive’s termination of employment with the Company. 
  
 (e) Voluntary Termination for Good Reason. If the Executive reasonably believes he has Good Reason (as defined below) to terminate employment he
must give the Board sixty (60) days prior written notice (or such shorter period as may be permitted by the Board) and a reasonable opportunity to cure, which shall be a minimum of thirty (30) days. If the Board fails to cure the Good Reason within
such reasonable time, the Executive may voluntarily terminate his employment with the Company prior to the end of the Employment Period. If the Executive voluntarily terminates his employment pursuant to this Section 4(e), the Executive shall be
entitled to receive the payments and benefits specified by Section 4(d), payable in accordance with and subject to the conditions of such Section. For purposes of this Agreement, “Good Reason” shall mean (i) the assignment to the Executive
of duties inconsistent with the position of President and Chief Executive Officer of the Company, or (ii) the assignment of the Executive to a position of lesser dignity or (iii) any Voluntary Termination by the Executive on any date that is at
least six months following the closing of a Sale of the Parent and no more than one year following such event. Any dispute which may arise concerning whether a voluntary termination of employment by the Executive is for Good Reason shall be resolved
by an arbitrator appointed pursuant to Section 15. 
  
 (f)
Other Voluntary Termination. Upon 60 days prior written notice to the Company (or such shorter period as may be permitted by the Board), the Executive may voluntarily terminate the Executive’s employment with the Company for any reason.
If the Executive voluntarily terminates the Executive’s employment pursuant to this Section 4(f), all obligations of the Company hereunder shall cease immediately, except that the Executive shall be entitled to the payments and benefits
specified in Sections 4(d)(i) and 4(d)(ii) hereof. 
  
 5.
Federal and State Withholding. The Company shall deduct from the amounts payable to the Executive pursuant to this Agreement the amount of all required federal, state and local withholding taxes in accordance with all applicable federal
employment taxes. 
  

 5 

 6. Noncompetition; Nonsolicitation. (a) General. The Executive acknowledges that in
the course of the Executive’s employment with the Company the Executive has and will become familiar with trade secrets and other confidential information concerning the Company, its subsidiaries and the Parent and that the Executive’s
services will be of special, unique and extraordinary value to the Company, its subsidiaries and the Parent. 
  
 (b) Noncompetition. The Executive agrees that during the period of the Executive’s employment with the Company, the period, if any, during
which the Executive is receiving payments from the Company pursuant to Section 4, and for a period of two years thereafter the Executive shall not in any manner, directly or indirectly, through any person, firm or corporation, alone or as a member
of a partnership or as an officer, director, stockholder, investor or employee of or consultant or other agent to any other corporation or enterprise or otherwise, engage or be engaged, or assist any other person, firm, corporation or enterprise in
engaging or being engaged, in any business, in which the Executive was involved or had knowledge, being conducted by, or contemplated by, the Company or any of its subsidiaries as of the termination of the Executive’s employment in any
geographic area in which the Company, any of its subsidiaries or the Parent is then conducting or is contemplating conducting such business. 
  
 (c) Nonsolicitation. The Executive further agrees that during the period of the Executive’s employment with the Company, the period if any
during which the Executive is receiving payments from the Company pursuant to Section 4, and for a period of three years thereafter, the Executive shall not (i) in any manner, directly or indirectly, induce or attempt to induce any employee of the
Company, any of its subsidiaries or the Parent to terminate or abandon his or her employment for any purpose whatsoever or (ii) in connection with any business to which Section 6(b) applies, call on, service, solicit or otherwise do business with
any customer of the Company, any of its subsidiaries or the Parent; provided, however, the Executive may solicit business with any customer of the Company, any of its subsidiaries or the Parent to the extent that such business is unrelated to the
business conducted or contemplated being conducted between the Company, its subsidiaries or the Parent and their customers. 
  
 (d) Exceptions. Nothing in this Section 6 shall prohibit the Executive from being (i) a stockholder in a mutual fund or a diversified investment
company or (ii) an owner of not more than two percent of the outstanding stock of any class of a corporation, any securities of which are publicly traded, so long as the Executive has no active participation in the business of such corporation.

  
 (e) Reformation. If, at any time of enforcement of this
Section 6, a court or an arbitrator holds that the restrictions stated herein are unreasonable under circumstances then existing, the parties hereto agree that the maximum period, scope or geographical area reasonable under such circumstances shall
be substituted for the stated period, scope or area and that the court or arbitrator shall be allowed to revise the restrictions contained herein to cover the maximum period, scope and area permitted by law. This Agreement shall not authorize a
court or arbitrator to increase or broaden any of the restrictions in this Section 6. 
  
 7. Nondisparagement. The Executive agrees that during the Executive’s employment with the Company and thereafter, the Executive shall not directly (or through any 
  

 6 

 other person or entity) make any public or private statements (whether oral or in writing) that are derogatory or
damaging to the Company or the Parent, including, but not limited to its businesses, activities, operations, affairs, reputation or prospects or any of their officers, employees, or current or former directors or shareholders. The Company also
agrees that during the Executive’s employment with the Company and thereafter, the Company shall not at any time make any defamatory public or private statements, whether oral or in writing, concerning the Executive. 
  
 8. Confidentiality. The Executive shall not, at any time during
the Employment Period or thereafter, make use of or disclose, directly or indirectly, any (i) trade secret or other confidential or secret information of the Company, any of its subsidiaries or the Parent or (ii) other technical, business,
proprietary or financial information of the Company, any of its subsidiaries or the Parent not available to the public generally (“Confidential Information”), except to the extent that such Confidential Information (a) becomes a matter of
public record or is published in a newspaper, magazine or other periodical or on electronic or other media available to the general public, other than as a result of any act or omission of the Executive, (b) is required to be disclosed by any law,
regulation or order of any court or regulatory commission, department or agency, provided that the Executive gives prompt notice of such requirement to the Company to enable the Company to seek an appropriate protective order, or (c) is required to
be used or disclosed by the Executive to perform properly the Executive’s duties under this Agreement. Promptly following the termination of the Employment Period, the Executive shall surrender to the Company all records, memoranda, notes,
plans, reports, computer tapes and software and other documents and data which constitute Confidential Information which the Executive may then possess or have under the Executive’s control (together with all copies thereof). 
  
 9. Standstill. The Executive hereby agrees that, unless
specifically requested in writing in advance by the Board, the Executive will not at any time during the period of the Executive’s employment with the Company, the period, if any, during which the Executive is receiving payments from the
Company pursuant to Section 4, and for a period of three years thereafter (and the Executive will not at any time during such period assist or encourage others to) participate, directly or indirectly in any activity that, if consummated, would
result in a Change in Control of the Parent. For purposes of this Section 9, a Change in Control of the Parent shall mean (a) any sale or other disposition of all or substantially all of the assets of the Parent, (b) any acquisition of more than 40%
of the then outstanding shares of common stock of the Parent, (c) any merger in which the existing stockholders of the Parent fail to own 50% or more of the corporation resulting from such merger or (d) any change in the membership of the Board such
that the individuals who, as of the date of this Agreement, constitute the Board (the “Incumbent Board”) cease for any reason to constitute at least a majority of such Board; provided, however, that any individual who
becomes a director of the Parent subsequent to the date of this Agreement whose election, or nomination for election by the Parent’s stockholders, was approved by the vote of at least a majority of the directors then comprising the Incumbent
Board shall be deemed a member of the Incumbent Board; and provided further, that no individual who was initially elected as a director of the Parent as a result of an actual or threatened election contest, as such terms are used in Rule 14a-l 1 of
Regulation 14A promulgated under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), or any other actual or threatened solicitation of proxies or consents by or on behalf of any individual, entity or group, including any
“person” within the meaning of Section 13(d) of the Exchange Act, other than the Board shall be deemed a member of the Incumbent Board. 
  

 7 

 10. Inventions. The Executive agrees to disclose fully and promptly to the Company in
writing, upon the Company’s request, all discoveries and improvements, patentable or otherwise, trade secrets and ideas, writings and copyrightable material which may be conceived by the Executive or developed or acquired by the Executive
during the Employment Period or the six-month period thereafter and which may pertain directly or indirectly to the business of the Company, any of its subsidiaries or the Parent (collectively, “Inventions”). All Inventions shall
constitute works made for hire owned by the Company and shall be the exclusive property of the Company. To the extent any Invention does not constitute a work made for hire, the Executive hereby assigns to the Company, without further consideration,
the Executive’s entire right, title and interest in and to such Invention, under patent, copyright, trade secret and trademark law, in perpetuity or for the longest period otherwise permitted by law. The Executive shall, upon the Company’s
request, execute, acknowledge and deliver to the Company all instruments and do all other acts which are necessary or in the Company’s opinion desirable to evidence more fully transfer of ownership of any Invention to the Company, or to enable
the Company, any of its subsidiaries or the Parent, to file and prosecute applications for, and to acquire, maintain and enforce, all patents, trademarks and copyrights in all countries. 
  
 11. Enforcement. The parties hereto agree that the Company, its subsidiaries and the Parent would be damaged
irreparably in the event that any provision of Section 6, 7, 8, 9 or 10 of this Agreement were not performed in accordance with its terms or were otherwise breached and that money damages would be an inadequate remedy for any such nonperformance or
breach. Accordingly, the Company and the Parent and their successors and permitted assigns shall be entitled, in addition to other rights and remedies existing in their favor, to an injunction or injunctions to prevent any breach or threatened
breach of any of such provisions and to enforce such provisions specifically (without posting a bond or other security). The Executive agrees that the Executive will submit to the personal jurisdiction of the courts of the State of Delaware in any
action by the Company or the Parent enforce an arbitration award against the Executive or to obtain interim injunctive or other relief pending an arbitration decision. 
  
 12. Representations. The Executive represents and warrants to the Company that (a) the execution, delivery and
performance of this Agreement by the Executive does not and will not conflict with, breach, violate or cause a default under any contract, agreement, instrument, order, judgment or decree to which the Executive is a party or by which the Executive
is bound, (b) the Executive is not a party to or bound by any employment agreement, noncompetition agreement or confidentiality agreement with any other person or entity and (c) upon the execution and delivery of this Agreement by the Company, this
Agreement shall be the valid and binding obligation of the Executive, enforceable in accordance with its terms. 
  
 13. Survival. Sections 6, 7, 8, 9 and 10 of this Agreement shall survive and continue in full force and effect in accordance with their
respective terms, notwithstanding any termination of the Employment Period. 
  
 14. Arbitration. Except as otherwise set forth in Section 12 hereof, any dispute or controversy between the. Company or the Parent and the Executive, whether arising 
  

 8 

 out of or relating to this Agreement, the breach of this Agreement, or otherwise, shall be settled by arbitration in the
State of Delaware administered by the American Arbitration Association, with any such dispute or controversy arising under this Agreement being so administered in accordance with its Commercial Rules then in effect, and judgment on the award
rendered by the arbitrator maybe entered in any court having jurisdiction thereof. The arbitrator shall have the authority to award any remedy or relief that a court of competent jurisdiction could order or grant, including, without limitation, the
issuance of an injunction. However, either party may, without inconsistency with this arbitration provision, apply to any court having jurisdiction over such dispute or controversy and seek interim provisional, injunctive or other equitable relief
until the arbitration award is rendered or the controversy is otherwise resolved. Except as necessary in court proceedings to enforce this arbitration provision or an award rendered hereunder, or to obtain interim relief, neither a party nor an
arbitrator may disclose the existence, content or results of any arbitration hereunder without the prior written consent of the Company and the Executive. The Company and the Executive acknowledge that this Agreement evidences a transaction
involving interstate commerce. Notwithstanding any choice of law provision included in this Agreement, the United States Federal Arbitration Act shall govern the interpretation and enforcement of this arbitration provision. 
  
 15. Notices. All notices and other communications required or
permitted hereunder shall be in writing and shall be deemed given when (a) delivered personally or by overnight courier to the following address of the other party hereto (or such other address for such party as shall be specified by notice given
pursuant to this Section) or (b) sent by facsimile to the following facsimile number of the other party hereto (or such other facsimile number for such party as shall be specified by notice given pursuant to this Section), with the confirmatory copy
