Third Amended Management Group Employee Severance Protection Plan



 Exhibit 10.25 
 THIRD AMENDED AND RESTATED 
 XTO ENERGY INC. 
 MANAGEMENT GROUP EMPLOYEE SEVERANCE PROTECTION PLAN 
 WHEREAS, the Amended and Restated XTO Energy Inc. Management Group Employee Severance Protection Plan (the “Prior Plan”) was adopted by the Board of Directors acting on behalf of XTO Energy Inc., a Delaware
corporation (the “Company”), effective as of August 20, 2002, and amended and restated effective as of August 15, 2006; and 
 WHEREAS, pursuant to Section 8.02 of the Prior Plan, the Prior Plan generally
may be amended by resolution adopted by two-thirds ( 2/3) of the Board of Directors of the Company; and 

WHEREAS, pursuant to a resolution adopted by two-thirds ( 2/3) of the Board of Directors of the Company, the Board of Directors of the Company desires to replace the Prior Plan with this
Plan and to amend and restate the Prior Plan to reflect certain provisions of Section 409A of the Internal Revenue Code of 1986, as amended (the “Code”) and any guidance issued thereunder. This amendment is intended as good faith
compliance with the requirements of Section 409A of the Code and is to be construed in accordance with Section 409A of the Code and the guidance issued thereunder; and 
 WHEREAS, the Board of Directors of the Company recognizes that the current business environment makes it difficult to attract and retain
highly qualified employees unless a certain degree of security can be offered to such individuals against organizational and personnel changes which could result from a Change in Control (as defined below) of the Company; and 
 WHEREAS, even rumors of acquisitions or mergers may cause employees to consider major career changes in an effort to ensure financial
security for themselves and their families; and 
 WHEREAS, the Company desires to ensure fair treatment of its employees,
and employees of certain subsidiaries of the Company which adopt this Plan as Participating Employers in the event of a Change in Control and to allow them to make critical career decisions without undue time pressure and financial uncertainty,
thereby increasing their willingness to remain with their Employer notwithstanding the outcome of a possible Change in Control transaction; and 
 WHEREAS, the Company recognizes that its employees and employees of Participating Employers will be involved in evaluating or negotiating any offers, proposals or other transactions which could result in a Change in
Control of the Company and believes that it is in the best interest of the Company and its stockholders for such employees to be in a position, free from personal financial and employment considerations, to assess objectively and pursue aggressively
the interests of the Company and its stockholders in making these evaluations and carrying on such negotiations; and 
 WHEREAS, the Board of Directors of the Company believes it is essential to provide such employees with compensation arrangements upon a Change in Control of the Company which provide such employees with individual financial security and
which are competitive with those of other corporations. 
 NOW, THEREFORE, in order to fulfill the above purposes, the
following plan has been developed and is hereby adopted.

 ARTICLE I. 
 ESTABLISHMENT OF PLAN 
 As of the Effective Date, the Company hereby amends and
restates the Third Amended and Restated XTO Energy Inc. Management Group Employee Severance Protection Plan, as set forth in this document (the “Plan”). 
 ARTICLE II. 
 DEFINITIONS 
 As used herein, the following words and phrases shall have the following respective meanings unless the context clearly indicates
otherwise. 
 Section 2.01 Base Salary. The amount a Participant receives as wages or salary on an annualized
basis, calculated immediately prior to a Change in Control. 
 Section 2.02 Board. The Board of Directors of the
Company. 
 Section 2.03 Bonus Amount. An amount equal to (i) the greater of a Participant’s two
most recent regular bonuses, if any, paid in the twelve (12) months prior to the date of the Change in Control, multiplied by two, plus (ii) the amount, if any, of the Participant’s monthly car allowance on the date of the
Change in Control, multiplied by twelve, plus (iii) the amount, if any, of any special bonuses awarded to a Participant during the three years preceding the Change in Control. A special bonus will include any bonus paid as a result of an
individual becoming an employee of the Company but will not include any bonus paid related to moving expenses. 
 Section 2.04 Cause. The Employer shall have “Cause” to terminate a Participant if the Participant (i) willfully and continually fails to substantially perform his or
her duties with the Employer (other than a failure resulting from the Participant’s incapacity due to physical or mental illness) which failure continues for a period of at least thirty (30) days after a written notice of demand for
substantial performance has been delivered to the Participant specifying the manner in which the Participant has failed to substantially perform, or (ii) willfully engages in illegal conduct, gross misconduct, or a clearly established violation
of Employer’s written policies and procedures, which is demonstrably and materially injurious to the Employer, monetarily or otherwise; provided, however, that no termination of the Participant’s employment shall be for Cause until
(x) there shall have been delivered to the Participant a copy of a written notice specifying in detail the particulars of the Participant’s conduct which violates either (i) or (ii) above, (y) the Participant shall have been
provided an opportunity to be heard by the Board (with the assistance of the Participant’s counsel if the Participant so desires), and (z) a resolution is adopted in good faith by two-thirds ( 2/3) of the Board confirming said violation. No act, nor failure to act, on the Participant’s part, shall be considered “willful” unless he or she has
acted or failed to act with an absence of good faith and without a reasonable belief that his or her action or failure to act was in the best interest of the Employer. Notwithstanding anything contained in this Plan to the contrary, no failure to
perform by the Participant after Notice of Termination is given by or to the Participant shall constitute Cause. 
 Section 2.05 Change in Control. A “Change in Control” shall mean the occurrence of one or more of the following events as objectively determined based upon all of the facts and circumstances without the exercise of
discretion by the Board: (i) a Change in Ownership of the Company; (ii) a Change in Effective Control of the Company; or (iii) a Change in the Ownership of a Substantial Portion of the Assets of the Company. For purposes hereof:

  

 - 2 - 








 (a) “Acting as a Group” shall mean “acting as a
group” as such phrase is defined under Section 409A of the Code and the regulations or other guidance issued thereunder. 
 (b) “Change in Ownership” shall mean that any one person or more than one person Acting as a Group acquires ownership of stock of the Company that, together with stock held by such person or group,
constitutes more than 50% of the total fair market value or total voting power of the stock of the Company; provided, however, that if any one person or more than one person Acting as a Group, is considered to own more than 50% of the total fair
market value or total voting power of the stock of the Company, the acquisition of any additional stock by the same person or persons shall not be considered a Change in Ownership or a Change in Effective Control. 
 (c) “Change in Effective Control” shall mean that either: 
 (i) any one person or more than one person Acting as a Group acquires (or has acquired during the 12-month period ending
on the date of the most recent acquisition by such person or persons) ownership of the stock of the Company possessing 35% or more of the total voting power of the stock of the Company; or 
 (ii) a majority of members of the Board is replaced during any 12-month period by directors whose appointment or election
is not endorsed by a majority of the members of the Board prior to the date of the appointment or election, provided that for purposes of this paragraph (ii) the Company refers solely to the “relevant corporation” (as such term is
defined in Section 409A of the Code and the regulations or other guidance issued thereunder) for which no other corporation is a majority shareholder. 
 Notwithstanding the foregoing, if any one person or more than one person Acting as a Group, is considered to effectively control the Company, the acquisition of additional control by the same
person or persons shall not be considered to cause a Change in Effective Control. 
 (d) “Change in
the Ownership of a Substantial Portion of the Assets” shall mean any one person or more than one person Acting as a Group acquires (or has acquired during the 12-month period ending on the date of the most recent acquisition by such person
or persons) assets from the Company that have a total Gross Fair Market Value equal to more than 40% of the total Gross Fair Market Value of all of the assets of the Company immediately prior to such acquisition or acquisitions. 
 A Change in the Ownership of a Substantial Portion of the Assets shall not be deemed to have occurred if Company assets
are transferred to: 
 (i) a shareholder of the Company (immediately before the asset transfer) in exchange
for or with respect to its stock; 
 (ii) an entity, 50% or more of the total value of voting power of which
is owned, directly or indirectly, by the Company; 
 (iii) a person, or more than one person Acting as a
Group, that owns, directly or indirectly, 50% or more of the total value or voting power of all the outstanding stock of the Company; or 
  

 - 3 - 








 (iv) an entity, at least 50% of the total value or voting power of which
is owned, directly or indirectly, by a person described in sub-paragraph (d)(iii). 
 For purposes of this
paragraph and except as otherwise provided, a person’s status is determined immediately after the transfer of assets. 
 (e) For purposes of this Section 2.05, “Gross Fair Market Value” shall mean the value of the Company’s assets, or the value of the Company’s assets being disposed of, determined
without regard to any liabilities associated with such assets. 
 Notwithstanding the foregoing provisions of this
Section 2.05, if a Participant’s employment with the Employer is terminated by the Employer other than for “Cause” prior to the date on which a Change in Control occurs, and it is reasonably demonstrated that such
termination (i) was at the request of a third party who has taken steps reasonably calculated to effect a Change in Control, or (ii) otherwise arose in connection with a Change in Control, then for all purposes hereof, such termination
shall be deemed to have occurred immediately following a Change in Control. 
 Notwithstanding the foregoing provisions of
this Section 2.05, in the event a benefit provided upon the occurrence of a Change in Control is subject to Section 409A of the Code, then, in lieu of the foregoing definition and to the extent necessary to comply with the
requirements of Section 409A of the Code, the definition of “Change in Control” for purposes of such benefit shall be the definition provided for under Section 409A of the Code and the regulations or other guidance issued
thereunder. 
 Notwithstanding anything herein to the contrary, under no circumstances will a change in the constitution of
the board of directors of any Subsidiary, a change in the beneficial ownership of any Subsidiary, the merger or consolidation of a Subsidiary with any other entity, the sale of all or substantially all of the assets of any Subsidiary or the
liquidation or dissolution of any Subsidiary constitute a “Change in Control” under this Plan. 
 Section 2.06

 Section 2.07 Effective Date. The date the Plan is
approved by the Board, or such other date as the Board shall designate in its resolution approving the Plan.

Participant’s “Employer” shall refer only to the employer of the Participant, and in no event shall be construed to refer to the Company as well. 
 Section 2.09 Good Reason. “Good Reason” shall mean the occurrence of any of the following events or conditions: 
 (a) a material diminution in the Participant’s authority, duties, or responsibilities (including reporting
responsibilities), except in connection with the termination of his or her employment for Cause, as a result of his or her disability or death, or by the Participant other than for Good Reason; 
 (b) a material diminution in the Participant’s Base Salary; or 
 (c) Employer’s requiring the Participant (without the consent of the Participant) to be based at any place outside a twenty-five
(25) mile radius of his or her place of employment

travel requirements prior thereto. 
 The Participant must provide notice to the Employer of the existence of the condition
constituting “Good Reason” within a period not to exceed ninety (90) days of the initial existence of the condition, upon the notice of which the Employer must be provided a period of at least thirty (30) days during which it may
remedy the condition and not be required to pay the amount. The separation from service must occur within the first two years following the initial existence of one or more of the Good Reason conditions arising without the consent of the
Participant.

his or her Employer as member of the Management Group or the Management Group II, except those employees that have a written employment contract with Employer or a Participating Employer.

for any termination of employment which sets forth in reasonable detail the facts and circumstances claimed to provide a basis for termination of the Participant’s employment under the provision so indicated; no purported termination of
employment shall be effective without such Notice of Termination.

is not entitled to a benefit under the terms of Article IV of the Plan; or (iii) the date on which he or she has received all of the benefits to which he or she is entitled under this Plan. 
 ARTICLE IV. 
 BENEFITS

 Section 4.01 Right to Benefits. 
 (a) After a Change in Control has occurred, a Participant shall be entitled to receive a Retention Benefit from the
Employer in the amount provided in Section 4.02 if he or she (i) remains employed by the Employer on the Payment Date or (ii) incurs a “separation from service” as defined by Section 409A of the Code prior to
such Participant’s Payment Date for any reason other than (A) termination by the Employer for Cause or (B) termination by the Participant for other than Good Reason. 
 (b) A Participant shall also be entitled to receive from the Employer a Severance Benefit in the amount provided in
Section 4.03 if, within two (2) years after a Change in Control, the Participant incurs a “separation from service” as defined by Section 409A of the Code for any reason other than (i) termination by the Employer
for Cause or (ii) termination by the Participant other than for Good Reason. 
 (c) Notwithstanding any
other provision of the Plan, the sale, divestiture, or other disposition of a Subsidiary shall not be deemed to be a termination of employment of employees employed by such Subsidiary, and such employees shall not be entitled to benefits from the
Company or any Participating Employer under this Plan as a result of such sale, divestiture, or other disposition, or as a result of any subsequent termination of employment. 
 Section 4.02 Amount of Retention Benefit. After a Participant is entitled to receive a Retention Benefit in accordance with Section 4.01(a), the Employer shall pay to the
Participant an amount in cash equal to: 
 (a) for the
Company’s Executive Vice Presidents and Senior Vice Presidents, two and one-half (2- 1/2) times the sum of (i) the
Participant’s Base Salary and (ii) the Bonus Amount, to be paid on or before ten (10) days after the Payment Date; 
 (b) for all other officers of Company, two (2) times the sum of (i) the Participant’s Base Salary and (ii) the Bonus Amount, to be paid on or before ten (10) days after the Payment Date; and

  

 - 6 - 








 (c) for all other Management Group Employees, one and one-half
(1.5) times the sum of (i) the Participant’s Base Salary and (ii) the Bonus Amount, to be paid on or before ten (10) days after the Payment Date. 
 Notwithstanding Section 2.01, for purposes of this Section 4.02, “Base Salary” shall mean the greatest of the Participant’s base salary on (i) the date
of the Change in Control, (ii) the Payment Date, or (iii) if the Participant incurs a “separation from service” as defined by Section 409A of the Code prior to the Payment Date, the Participant’s Termination Date.

 Section 4.03 Amount of Severance Benefit. If a Participant’s employment is terminated in circumstances
entitling him or her to a Severance Benefit as provided in Section 4.01(b), such Participant shall be entitled to the following benefits: 
 (a) For a period of eighteen (18) months subsequent to the Participant’s Termination Date, the Employer shall at its sole expense continue on behalf of the Participant and his or her
covered dependents and beneficiaries, all medical, dental, vision, and health benefits and insurance coverage that were being provided to the Participant immediately prior to his or her Termination Date. The benefits provided in this
Section 4.03(a) shall be no less favorable to the Participant, in terms of amounts and deductibles and costs to him or her, than the coverage provided the Participant under the plans providing such benefits at the time Notice of
Termination is given. The Employer’s obligation hereunder to provide a benefit shall terminate if the Participant obtains comparable coverage under a subsequent employer’s benefit plan. For purposes of the preceding sentence, benefits will
not be comparable during any waiting period for eligibility for such benefits or during any period during which there is a preexisting condition limitation on such benefits. The Employer also shall pay a lump sum equal to the amount of any
additional income tax payable by the Participant and attributable to the benefits provided under this Section 4.03(a) at the time such tax is imposed upon the Participant. In the event that the Participant’s participation in any
such coverage is barred under the general terms and provisions of the plans and programs under which such coverage is provided, or any such coverage is discontinued or the benefits thereunder are materially reduced, the Employer shall provide
benefits to the Participant, or ensure that such benefits are provided to the Participant, that are substantially similar to those which the Participant was entitled to receive under such coverage immediately prior to the Notice of Termination. At
the end of the period of coverage set forth above, the Participant shall have the option to have assigned to him or her at no cost to the Participant and with no apportionment of prepaid premiums, any assignable insurance owned by the Employer and
relating specifically to the Participant, and the Participant shall be entitled to all health and similar benefits that are or would have been made available to the Participant under law. 
 (b) The Employer shall transfer to the Participant, within thirty (30) days after the Participant’s Termination
Date, any right, title or ownership in any club memberships provided by the Employer for use by the Participant. 
 (c) The Employer shall transfer to the Participant, within thirty (30) days after the Participant’s Termination Date, any right, title or ownership in any life insurance owned by the Employer on the Participant’s life.

 Section 4.04 Vesting of Stock Plans. In the event of a Change in Control, each Participant shall be entitled
to the following benefits: 
  

 - 7 - 








 (a) Unless otherwise specifically provided to the contrary in any option
agreement, restricted stock agreement, or other agreement relating to equity-type compensation between the Participant and the Employer, all units, stock options, incentive stock options, performance shares, stock appreciation rights and royalty
trust options (under the XTO Energy Inc. Amended and Restated 2004 Stock Incentive Plan, as amended or any other plan or arrangement) (hereafter sometimes referred to as the “Rights”) held by the Participant immediately prior to the Change
in Control, and any such Rights received by the Participant after such Change in Control (whether or not received in exchange for or in substitution for existing Rights), shall immediately become one hundred percent (100%) vested and
exercisable, and the Participant shall become one hundred percent (100%) vested in all shares of restricted stock held by or for the benefit of the Participant; provided, however, that to the extent the Employer is unable to provide for such
acceleration of vesting with respect to any such Rights or shares of restricted stock, the Employer shall provide in lieu thereof a lump-sum cash payment within thirty (30) days after the Change in Control, equal to the difference between the
total value of such unaccelerated Rights or shares of restricted stock (the “Stock Rights”) as of the Change in Control and the total value if such Stock Rights had accelerated vested. The value of such accelerated vesting in the
Participant’s Stock Rights shall be determined by the Board in good faith based on a valuation performed by an independent consultant selected by the Board; any such Stock Rights which are not in existence on the Change in Control shall be
valued as of the date of the Change in Control. 
 (b) Unless otherwise specifically provided to the contrary
in any option agreement between the Participant and the Employer, any previously unexercised options under any such option agreement shall not terminate or be forfeited and shall remain outstanding until the latest date on which the option would
otherwise expire under the terms of such agreement had the Participant’s employment not terminated. However, with respect to any option (or portion of an option) for which either (i) the Employer is unable to provide for the extension of
the post-termination exercise period as provided in the preceding sentence, or (ii) providing for the extension would cause an option (or a portion of an option) to be subject to Section 409A of the Code, then the option (or portion of an
option) shall not be so extended and the Employer shall make a lump-sum cash payment to the Participant, within thirty (30) days after the Participant’s Termination Date, equal to the value, as of the Participant’s Termination Date,
of the extension of the post-termination exercise periods for all options (or portions of options) which cannot be so extended. The value of such extension shall be determined by the Board in good faith based on a valuation performed by an
independent consultant selected by the Board. Notwithstanding the foregoing, if, in accordance with the foregoing, the post-termination exercise periods of an incentive stock option held by the Participant may be extended without causing application
of Section 409A of the Code, the extension of such options under this Section 4.04(b) shall only be applicable if the Participant has not exercised such option within three (3) months after the Participant’s Termination
Date, and, in that event, such options shall immediately convert to nonqualified stock options. 
 Section 4.05
Mitigation or Set-off of Amounts Payable Hereunder. The Participant shall not be required to mitigate the amount of any payment provided for in this Article IV by seeking other employment or otherwise, and except at otherwise provided
in Section 4.03(a), nor shall the amount of any payment provided for in this Article IV be reduced by any compensation earned by the Participant as the result of employment by the Company or any successor after the Payment Date or
by another employer after the Termination Date, or otherwise. The Employer’s obligations hereunder also shall not be affected by any set-off, counterclaim, recoupment, defense, or other claim, right or action which the Employer may have against
the Participant. 
  

 - 8 - 








 Section 4.06 Company Guarantee of Plan Benefits. In the event a Participant
becomes entitled to receive from the Employer a benefit under this Article IV and such Employer fails to pay such benefit, the Company shall assume the obligation of such Employer to pay such benefit. In consideration of the Company’s
assumption of the obligation to pay any such Plan Benefits, the Company (as the source of payment of benefits under the Plan) shall be subrogated to any recovery (irrespective of whether there is recovery from the third party of the full amount of
all claims against the third party) or right to recovery of either a Participant or his or her legal representative against the Employer or any other person or entity. The Participant or his or her legal representative shall cooperate in doing what
is reasonably necessary to assist the Company in exercising such rights, including but not limited to notifying the Company of the institution of any claim for such Plan Benefits, and notifying the defendant of the Company’s subrogation rights.
Neither the Participant nor his or her legal representative shall do anything after a loss to prejudice such rights. 
 In
its sole discretion, the Company reserves the right to prosecute an action in the name of the Participant or his or her legal representative against any party potentially liable to the Participant for such Plan Benefits. The Company shall have the
absolute discretion to settle subrogation claims on any basis it deems warranted and appropriate under the circumstances. 
 The Company shall be entitled, to the extent of any payments made to or on behalf of a Participant, to be paid first from the proceeds of any settlement or judgment that may result from the exercise of any rights of recovery asserted by or
on behalf of a Participant or his or her legal representative against any party liable for such Plan Benefits. The Company shall be reimbursed by the Participant or his or her legal representative an amount of money equal to all sums paid by the
Employer under the Plan to or on behalf of the Participant. If the Company prosecuted such action, it shall be entitled to reimbursement for all attorneys’ fees, costs and expenses incurred in such prosecution. The right is also hereby given
the Company to receive directly from the Employer or any third party(ies), attorney(s) or insurance company(ies) an amount equal to the amount paid to the Participant. 
 Section 4.07 Election of Plan Benefits. A Participant who is entitled to severance benefits under an employment agreement with the Employer may elect, in writing within ten
(10) days after his or her Termination Date, to receive the Plan Benefits provided under this Plan in lieu of, but not in addition to, such other severance benefits as may be provided by such other agreement. In the event that no election is
made, the Participant shall forego his or her right to receive the Plan Benefits provided under this Plan. In the event a Participant’s election (or right to make an election) under this Section 4.07 would result in a violation of
Section 409A of the Code and as a result the Participant would be subject to the taxes described in Section 409A(a)(1) of the Code, the Participant shall not be entitled to make an election and the Participant shall forego his or her right
to receive the Plan Benefits provided under this Plan. 
 Section 4.08 Section 409A of the Code; Delay of
Payments. The terms of this Plan have been designed to comply with the requirements of Section 409A of the Code, as amended, where applicable, and shall be interpreted and administered in a manner consistent with such intent.
Notwithstanding anything to the contrary in this Plan, (i) if upon the Participant’s Termination Date, the Participant is a “specified employee” within the meaning of Section 409A of the Code, and the deferral of any amounts
otherwise payable under this Plan as a result of the Participant’s termination of employment is necessary in order to prevent any accelerated or additional tax to the Participant under Section 409A of the Code, then the Employer will delay
the payment of any such amounts hereunder until the date that is six (6) months following the Participant’s Termination Date at which time any such delayed amounts will be paid to the Participant in a single lump sum, with interest from
the date otherwise payable, at the prime rate as published in The Wall Street Journal on the Participant’s Termination Date, and (ii) if any other payments of money or other benefits due to the Participant hereunder could cause the
application of an accelerated or additional tax under Section 409A of the Code, such payments or other benefits shall be 

  

 - 9 - 








 
delayed if such delay will make such payment or other benefits compliant under Section 409A of the Code. 
 ARTICLE V. 
 TERMINATION OF
EMPLOYMENT 
 Section 5.01 Written Notice Required. Any purported termination of employment, either by the
Employer or by the Participant, shall be communicated by written Notice of Termination to the other. 
 Section 5.02
Termination Date. In the case of the Participant’s death, the Participant’s Termination Date shall be his or her date of death. In all other cases, the Participant’s Termination Date shall be the date specified in the Notice of
Termination subject to the following: 
 (a) If the Participant’s employment is terminated by the
Employer for Cause, the date specified in the Notice of Termination shall be at least thirty (30) days from the date the Notice of Termination is given to the Participant; and 
 (b) If the Participant terminates his or her employment for Good Reason: (i) the Notice of Termination shall be given
to the Employer within ninety (90) days after the occurrence of the event or condition on which the Participant may terminate his or her employment for Good Reason; (ii) upon receipt of the Notice of Termination, the Employer must be
provided a period of at least thirty (30) days during which it may remedy the condition; and (iii) the Participant’s Termination Date shall be no earlier than thirty (30) days after the Employer’s receipt of the Notice of
Termination, but no later than two years after the initial occurrence of the event or condition constituting Good Reason. 
 ARTICLE VI.

 ADDITIONAL PAYMENTS BY THE COMPANY 
 Section 6.01 Gross-Up Payment. In the event it shall be determined that any payment or distribution of any type by the Employer to or for the benefit of the Participant, whether paid or payable or
distributed or distributable pursuant to the terms of this Plan or otherwise (the “Total Payments”), would be subject to the excise tax imposed by Section 4999 of the Code or any interest or penalties with respect to such excise tax
(such excise tax, together with any such interest and penalties, are collectively referred to as the “Excise Tax”), then the Participant shall be entitled to receive an additional payment (a “Gross-Up Payment”) in an amount such
that, after payment by the Participant of all taxes (including additional excise taxes under said Section 4999 and any interest, and penalties imposed with respect to any taxes) imposed upon the Gross-Up Payment, the Participant shall have an
amount of the Gross-Up Payment equal to the Excise Tax imposed upon the Total Payments. The Company shall pay the Gross-Up Payment to the Participant within twenty (20) business days after the Payment Date or the Termination Date, whichever is
applicable. 
 Section 6.02 Determination By Accountant. All determinations required to be made under this
Article VI, including whether a Gross-Up Payment is required and the amount of such Gross-Up Payment, shall be made by the independent accounting firm retained by the Company on the date of Change in Control (the “Accounting Firm”),
which shall provide detailed supporting calculations both to the Company and the Participant within fifteen (15) business days of the Payment Date or Termination Date, whichever is applicable, or such earlier time as is requested by the
Company. If the Accounting Firm determines that no Excise Tax is payable by the Participant, it shall furnish the Participant with an opinion that he or she has substantial authority not to report any Excise Tax on his or her federal income tax
return. Any determination by the Accounting Firm shall be binding upon the Company and the 

  

 - 10 - 








 
Participant. As a result of the uncertainty in the application of Section 4999 of the Code at the time of the initial determination by the Accounting
Firm hereunder, it is possible that Gross-Up Payments which will not have been made by the Company should have been made (“Underpayment”), consistent with the calculations required to be made hereunder. In the event that the Company
exhausts its remedies pursuant to Section 6.03 and the Participant thereafter is required to make a payment of any Excise Tax, the Accounting Firm shall determine the amount of the Underpayment that has occurred and any such Underpayment
shall be promptly paid by the Company to or for the benefit of the Participant. Notwithstanding the foregoing, in no event shall the Underpayment be paid to the Participant later than the end of the calendar year next following the calendar year in
which such taxes are remitted. 
 Section 6.03 Notification Required. The Participant shall notify the Company in
writing of any claim by the Internal Revenue Service that, if successful, would require the payment by the Company of the Gross-Up Payment. Such notification shall be given as soon as practicable but no later than ten (10) business days after
the Participant knows of such claim and shall apprise the Company of the nature of such claim and the date on which such claim is requested to be paid. The Participant shall not pay such claim prior to the expiration of the thirty (30)-day period
following the date on which he or she gives such notice to the Company (or such shorter period ending on the date that any payment of taxes with respect to such claim is due). If the Company notifies the Participant in writing prior to the
expiration of such period that it desires to contest such claim, the Participant shall: 
 (a) give the
Company any information reasonably requested by the Company relating to such claim, 
 (b) take such action in
connection with contesting such claim as the Company shall reasonably request in writing from time to time, including, without limitation, accepting legal representation with respect to such claim by an attorney reasonably selected by the Company,

 (c) cooperate with the Company in good faith in order to effectively contest such claim, 
 (d) permit the Company to participate in any proceedings relating to such claim, provided, however, that the Company shall
bear and pay directly all costs and expenses (including additional interest and penalties) incurred in connection with such contest and shall indemnify and hold the Participant harmless, on an after-tax basis, for any Excise Tax or income tax,
including interest and penalties with respect thereto, imposed as a result of such representation and payment of costs and expenses. Without limitation on the foregoing provisions of this Section 6.03, the Company shall control all
proceedings taken in connection with such contest and, at its sole option, may pursue or forgo any and all administrative appeals, proceedings, hearings and conferences with the taxing authority in respect of such claim and may, at its sole option,
either direct the Participant to pay the tax claimed and sue for a refund, or contest the claim in any permissible manner, and the Participant agrees to prosecute such contest to a determination before any administrative tribunal, in a court of
initial jurisdiction and in one or more appellate courts, as the Company shall determine; provided, however, that if the Company directs the Participant to pay such claim and sue for a refund, the Company shall advance the amount of such payment to
the Participant, on an interest-free basis and shall indemnify and hold the Participant harmless, on an after-tax basis, from any Excise Tax or income tax, including interest or penalties with respect thereto, imposed with respect to such advance or
with respect to any imputed income with respect to such advance; and further provided that any extension of the statute of limitations relating to payment of taxes for the taxable year of the Participant with respect to which such contested amount
is claimed to be due is limited solely to such contested amount. Furthermore, the Company’s control of the contest 

  

 - 11 - 








 
shall be limited to issues with respect to which a Gross-Up Payment would be payable hereunder and the Participant shall be entitled to settle or contest, as
the case may be, any other issue raised by the Internal Revenue Service or any other taxing authority. 
 Section 6.04
Repayment. If, after the receipt by the Participant of an amount advanced by the Company pursuant to Section 6.03, the Participant becomes entitled to receive any refund with respect to such claim, the Participant shall (subject
to the Company’s complying with the requirements of Section 6.03) promptly pay to the Company the amount of such refund (together with any interest paid or credited thereon after taxes applicable thereto). If, after the receipt by
the Participant of an amount advanced by the Company pursuant to Section 6.03, a determination is made that the Participant shall not be entitled to any refund with respect to such claim and the Company does not notify the Participant in
writing of its intent to contest such denial of refund prior to the expiration of thirty days after such determination, then such advance shall be forgiven and shall not be required to be repaid and the amount of such advance shall offset, to the
extent thereof, the amount of Gross-Up Payment required to be paid. 
 ARTICLE VII. 
 SUCCESSORS TO COMPANY 
 Section 7.01 Successors. This Plan shall bind any successor (whether direct or indirect, by purchase, merger, consolidation or otherwise) to all or substantially all of the business and/or assets of the Company, in the same
manner and to the same extent that the Company would be obligated under this Plan if no succession had taken place. In the case of any transaction in which a successor would not, by the foregoing provision or by operation of law, be bound by this
Plan, the Company shall require such successor expressly and unconditionally to assume and agree to perform the Company’s obligations under this Plan, in the same manner and to the same extent that the Company would be required to perform if no
such succession had taken place. As used herein, the “Company” shall mean the Company as hereinbefore defined and any successor to its business and/or assets as aforesaid which executes and delivers the agreement provided for in this
Section 7.01 or which otherwise becomes bound by all the terms and provisions hereof by operation of law. 
 ARTICLE VIII. 

 DURATION, AMENDMENT, PLAN TERMINATION

 Section 8.01 Duration. This Plan shall
continue in effect until terminated in accordance with Section 8.02. If a Change in Control occurs, this Plan shall continue in full force and effect, and shall not terminate or expire, until after all Participants who have become

The Plan may be terminated or amended in any respect by resolution adopted by two-thirds ( 2/3) of the Board; provided, however, that except to the extent necessary to prevent the current taxation of a Participant under Section 409A of the Code and any guidance issued
thereunder as so determined by two-thirds ( 2/3) of the Board in its sole discretion, no such amendment or termination of
the Plan may be made if such amendment or termination would adversely affect any right of a Participant who became a Participant prior to the later of (a) the date of adoption of any such amendment or termination, or (b) the effective date
of any such amendment or termination. The Plan shall not be subject to amendment, change, substitution, deletion, revocation, or, except as provided in Section 8.01 above, termination in any respect whatsoever following a Change in
Control; provided, however, that the Board may amend, change, substitute, delete, revoke, or otherwise modify the terms of this Plan if the Board determines, in its sole discretion, that such amendment, change,

the Company an appropriate instrument agreeing to be bound as an Employer by all of the terms of the Plan (as it may be amended from time to time) with respect to its eligible employees. The adoptive instrument may contain such changes and
amendments in the terms and provisions of the Plan as adopted by such Subsidiary as may be desired by such Subsidiary and acceptable to the Company. The adoptive instrument shall specify the effective date of such adoption of the Plan and shall
become as to such adopting Subsidiary a part of this Plan.
