REPRESENTATIONS AND WARRANTIES OF THE STOCKHOLDER

 

The Stockholder represents and warrants, on his
own account with respect to the Subject Shares, to Parent and Purchaser that:

 

2.1.          Authorization;
Binding Agreement.  The Stockholder has full legal capacity, right and authority to execute and deliver this
Agreement and to perform the Stockholder’s obligations hereunder.  This Agreement has been duly and validly executed
and delivered by the Stockholder and constitutes a valid and binding obligation of the Stockholder enforceable against the Stockholder
in accordance with its terms, subject to the effects of bankruptcy, insolvency, fraudulent conveyance, reorganization, moratorium
and other similar Laws relating to or affecting creditors’ rights generally and general equitable principles (whether considered
in a proceeding in equity or at law) (the “Enforceability Exceptions”).  If the Stockholder is married,
and any of the Subject Shares of the Stockholder constitute community property or otherwise need spousal or other approval for
this Agreement to be legal, valid and binding, this Agreement has been duly executed and delivered by the Stockholder’s spouse
and, assuming the due authorization, execution and delivery hereof by Parent and Purchaser,
is enforceable against the Stockholder’s spouse in accordance with its terms, subject to the Enforceability Exceptions.

 

2.2.          Non-Contravention.  Neither
the execution and delivery of this Agreement by the Stockholder nor the consummation of the transactions contemplated hereby nor
compliance by the Stockholder with any provisions herein will (a) require any consent, approval, authorization or permit of, or
filing with or notification to, any supranational, national, foreign, federal, state or local government or subdivision thereof,
or governmental, judicial, legislative, executive, administrative or regulatory authority on the part of the Stockholder, except
for compliance with the applicable requirements of the Securities Act, the Exchange Act or any other United States federal securities
laws and the rules and regulations promulgated thereunder, (b) violate, conflict with, or result in a breach of any provisions
of, or require any consent, waiver or approval or result in a default or loss of a benefit (or give rise to any right of termination,
cancellation, modification or acceleration or any event that, with the giving of notice, the passage of time or otherwise, would
constitute a default or give rise to any such right) under any of the terms, conditions or provisions of any note, license, agreement,
contract, indenture or other instrument or obligation to which the Stockholder is a party or by which the Stockholder or any of
his assets may be bound, (c) result (or, with the giving of notice, the passage of time or otherwise, would result) in the
creation or imposition of any mortgage, lien, pledge, charge, security interest or encumbrance of any kind on any asset of the
Stockholder (other than one created by Parent or Purchaser), or (d violate any order, writ, injunction, decree, statute, rule
or regulation applicable to the Stockholder or by which any of his assets are bound.

 

2.3.          Ownership
of Subject Shares; Total Shares.  Such Stockholder is the record and beneficial owner (as defined in Rule 13d-3
under the Exchange Act) of all the Stockholder’s Subject Shares and has good and marketable title to all such Subject Shares
free and clear of any liens, claims, proxies, voting trusts or agreements, options, rights, understandings or arrangements or any
other encumbrances or restrictions whatsoever on title, transfer or exercise of any rights of a stockholder in respect of such
Subject Shares (collectively,

 

    	-3-

    	 

    

 

“Encumbrances”), except for
any such Encumbrance that may be imposed pursuant to (a) this Agreement and (b) any applicable restrictions on transfer under the
Securities Act or any state securities law (collectively, “Permitted Encumbrances”).  For the avoidance
of doubt, the fact that the Subject Shares are held in a margin account shall not be deemed to be an Encumbrance hereunder. The
Subject Shares constitute all of the shares of “voting stock” of the Company of which the Stockholder is the “owner”
(as such terms are defined in Section 203 of the DGCL) as of the time that the Company Board of Directors approved the Merger Agreement.

 

2.4.          Voting
Power.  The Stockholder has full voting power with respect to all the Stockholder’s Subject Shares, and
full power of disposition, full power to issue instructions with respect to the matters set forth herein and full power to agree
to all of the matters set forth in this Agreement, in each case with respect to all the Stockholder’s Subject Shares.  None
of the Stockholder’s Subject Shares are subject to any stockholders’ agreement, proxy, voting trust or other agreement
or arrangement with respect to the voting of such Subject Shares, except as provided hereunder.

 

2.5.          Reliance.  The
Stockholder understands and acknowledges that Parent and the Merger Subs are entering into the Merger Agreement in reliance upon
the Stockholder’s execution, delivery and performance of this Agreement.

of Litigation.  As of the date hereof, there are no actions, suits, inquiries, investigations, proceedings or
claims of any nature or subpoenas, civil investigative demands or other requests for information (each, a “Proceeding”)
relating to potential material violations of Law pending against, or, to the knowledge of the Stockholder, threatened in writing
against the Stockholder or any of the Stockholder’s properties or assets (including any shares of Company Common Stock beneficially
owned by the Stockholder) before or by any Governmental Entity that could reasonably be expected to prevent or materially delay
or impair the consummation by the Stockholder of the transactions contemplated by this Agreement or otherwise materially impair
the Stockholder’s ability to perform his obligations hereunder.

 

2.7.          Brokers.  No
broker, finder, financial advisor, investment banker or other person is entitled to any brokerage, finder’s, financial advisor’s
or other similar fee or commission from the Company in connection with the transactions contemplated hereby based upon arrangements

of Parent and Purchaser in accordance with its terms, except as enforceability may be limited by the Enforceability Exceptions.

 

ARTICLE IV

ADDITIONAL COVENANTS

 

The Stockholder hereby covenants and agrees that
until the termination of this Agreement:

 

4.1.          No
Transfer; No Inconsistent Arrangements.   Except as provided hereunder or under the Merger Agreement, from

or permit to exist any Encumbrance, other than Permitted Encumbrances, on any of the Stockholder’s Subject Shares, (ii) transfer,
sell, assign, gift, hedge, pledge or otherwise dispose of, or enter into any derivative arrangement with respect to (collectively,

any interest therein, (iv) grant or permit the grant of any proxy, power-of-attorney or other authorization or consent in

Subject Shares, or (vi) take or permit any other action that would in any way restrict, limit or interfere with the performance
of the Stockholder’s obligations hereunder or otherwise make any representation or warranty of the Stockholder herein untrue
or incorrect.  Any action taken in violation of the foregoing sentence shall be null and void ab initio.  Notwithstanding
the foregoing, the Stockholder may Transfer Subject Shares (i) to any member of the Stockholder’s immediate family,
(ii) to a trust for the sole benefit of the Stockholder or any member of the Stockholder’s immediate family, the sole
trustees of which are the Stockholder or any member of the Stockholder’s immediate family, (iii) to a charitable organization,
including but not limited to, a private charitable foundation under Section 501(c)(3) of the Internal Revenue Code, or (iv) by
will or under the laws of intestacy upon the death of the Stockholder, provided, that a Transfer
referred to in clause (i) through (iv) of this sentence shall be permitted only if all of the representations and warranties
in this Agreement with respect to the Stockholder would be true and correct upon such Transfer and the transferee agrees in writing,
in a manner reasonably acceptable to Parent, to accept such Subject Shares subject to the terms of this Agreement and to be bound
by the terms of this Agreement and to agree and acknowledge that such person shall constitute a Stockholder for all purposes of
this Agreement.  If any involuntary Transfer of any of the Stockholder’s Subject Shares in the Company shall occur

or court sale), the transferee (which term, as used herein, shall include any and all transferees and subsequent transferees of

    	-5-

    	 

    

 

shall take and hold such Subject Shares subject
to all of the restrictions, liabilities and rights under this Agreement, which shall continue in full force and effect until valid
termination of this Agreement.  Notwithstanding the foregoing, the Stockholder may make Transfers of his Subject Shares
as Parent may agree in writing in its sole discretion.

that may arise in connection with the Offer and the First Merger.

 

4.3.          Documentation
and Information.  The Stockholder shall not make any public announcement regarding this Agreement and the transactions
contemplated hereby without the prior written consent of Parent (such consent not to be unreasonably withheld), except as may be
required by applicable Law or in compliance with the rules or regulations of the SEC, any other Government Entity or any stock
exchange as determined in the reasonable discretion of the Stockholder in consultation with his counsel (provided that reasonable
notice of any such disclosure will be provided to Parent).  The Stockholder consents to and hereby authorizes Parent
and Purchaser to publish and disclose in all documents and schedules filed with the SEC, and any press release or other disclosure
document that Parent or Purchaser reasonably determines to be necessary in connection with the Offer, the First Merger and any
other transactions contemplated by the Merger Agreement, the Stockholder’s identity and ownership of the Subject Shares,
the existence of this Agreement and the nature of the Stockholder’s commitments and obligations under this Agreement, and
the Stockholder acknowledges that Parent and Purchaser will file this Agreement or a form hereof with the SEC or any other Governmental
Entity.  The Stockholder agrees to promptly give Parent any information it may reasonably require for the preparation
of any such disclosure documents, and the Stockholder agrees to promptly notify Parent of any required corrections with respect
to any written information supplied by the Stockholder specifically for use in any such disclosure document, if and to the extent
that any such information shall have become false or misleading in any material respect.  

 

4.4.          Adjustments.  In
the event of any stock split, stock dividend, merger, reclassification, combination, exchange of shares or the like of the capital
stock of the Company affecting the Subject Shares, the terms of this Agreement shall apply to the resulting securities.  

 

4.5.          Waiver
of Certain Actions.  The Stockholder hereby agrees not to commence or participate in, and to take all actions
necessary to opt out of any class in any class action with respect to, any claim, derivative or otherwise, against Parent, the
Company, the Merger Subs or any of their respective successors (a) challenging the validity of, or seeking to enjoin or delay
the operation of, any provision of this Agreement or the Merger Agreement (including any claim seeking to enjoin or delay the consummation
of the Offer or the Mergers) or (b) alleging a breach of any duty of the Company Board of Directors in connection with the
Merger Agreement, this Agreement or the transactions contemplated thereby or hereby.  

 

4.6.          No
Solicitation.  The Stockholder shall, and shall cause his Affiliates (which term, solely for purposes of this
Section 4.6, shall be deemed to exclude the Company and its Subsidiaries) and his and their respective directors, officers,
managing partners and employees

 

    	-6-

    	 

    

 

and their respective agents, financial advisors,
investment bankers, attorneys and accountants: (i) to immediately cease and cause to be terminated any solicitation, encouragement,
discussions or negotiations with any persons (other than Parent) that may be ongoing with respect to a Company Takeover Proposal
and (ii) not to, directly or indirectly, (A) solicit, initiate, knowingly encourage or knowingly facilitate any inquiries
regarding, or the making of any proposal or offer that constitutes, or could reasonably be expected to lead to, a Company Takeover
Proposal, (B) engage in, continue or otherwise participate in any discussions or negotiations regarding, or furnish to any
other person any information in connection with or for the purpose of knowingly encouraging or facilitating, a Company Takeover
Proposal (other than, solely in response to an unsolicited inquiry, to refer the inquiring person to this Section 4.6 and
to Section 6.3 of the Merger Agreement and to limit his conversation or other communication exclusively to such referral), (C)
encourage or recommend any other holder of Company Common Stock to vote against the Transactions (including the First Merger) or
to not tender shares of Company Common Stock into the Offer, or (D) support, recommend, endorse or approve, or propose to support,
recommend, endorse or approve, any Company Takeover Proposal or enter into any letter of intent or similar document, agreement,
commitment or agreement in principle relating to or facilitating a Company Takeover Proposal.  The foregoing notwithstanding,
no announcement or disclosure made by, nor any action taken by, the Board of Directors of the Company (including, without limitation,
a Company Adverse Recommendation Change) shall be deemed to be a breach of this Section 4.6 by the Stockholder or Affiliate
that serves as a director of the Company so long as such announcement, disclosure or action does not constitute a breach of the
Merger Agreement by the Company or a breach for which the Company was responsible for preventing.

 

4.7.          Registration
Rights.  Between the date of the initial filing of the Offer S-4 (as defined in the Merger Agreement) and the
Closing, Parent and the Stockholder shall use commercially reasonable efforts to negotiate in good faith, in conjunction with certain
other principal stockholders of the Company entering into a voting and support agreement concurrently with the Stockholder’s
entry into this Agreement, a usual and customary registration rights agreement that provides for the registration, for resale on
a continuous basis, of all of the equity securities of Parent owned by the Stockholder and such other principal stockholders and
that contains customary provisions related to cooperation, black-out periods and indemnification.  The Stockholder acknowledges
and agrees that (1) compliance with this Section 4.7 by Parent is not a condition to any other obligation of the Stockholder
contained in this Agreement (including, without limitation, the obligations set forth in Section 1.1), and (2) that no failure
of compliance by Parent, nor the failure of the parties to agree to or enter into a registration rights agreement, shall affect
or limit or excuse non-performance of any other obligation of the Stockholder contained in this Agreement (including, without limitation,
the obligations set forth in Section 1.1).

2015 LONG-TERM INCENTIVE (LTI) PLAN

PURPOSE OF THE PLAN
The purpose of the 2015 Long-Term Incentive Plan (the “Plan”) is to drive shareholder value by providing incentives for Selected Participants (defined below) to deliver increasing return on net assets for Advanced Energy Industries, Inc. and its consolidated subsidiaries.
EFFECTIVE DATE
The Plan covers a one-year performance period from January 1, 2015 to December 31, 2015 (the “Plan Term”) and supersedes the Company’s 2012-2014 Long-Term Incentive Plan. During the Plan Term, Selected Participants will not be entitled to stock options, restricted stock units, performance stock units or other equity awards under the 2008 Plan (defined below), except for awards granted pursuant to this Plan or otherwise determined by the Compensation Committee of the Board of Directors.
DEFINITIONS
For the purposes of this document only, the following definitions will apply:
“Award” or “award” shall mean an award consisting of Performance Stock Units (PSUs) or Restricted Stock Units (RSUs) pursuant to the Plan.
 “Board of Directors” shall mean the Board of Directors of the Company.
“Committee” shall mean the Compensation Committee of the Board of Directors. Grants and Awards are approved by the Committee.  
“Company” shall mean Advanced Energy Industries, Inc., a Delaware Corporation, and its consolidated subsidiaries.
“Fiscal Year” shall mean the 12-month period ending on December 31, 2015.
“Grant” or “grant” shall mean a grant of Stock Options (SOs) pursuant to the Plan.
“Performance Stock Unit (PSU) Award” or “PSU” shall mean a performance based restricted stock unit award under the 2008 Plan as evidenced by an award agreement that represents a commitment to provide the Selected Participant a specific number of shares of Company common stock on a future date contingent upon meeting or exceeding the performance metrics defined herein as certified by the Committee. As set forth below, the delivery of Company shares may be satisfied in whole or in part with cash as determined by the Committee.
Restricted Stock Unit (RSU) Award or “RSU” shall mean a restricted stock unit award subject to vesting based on the lapse of one or more defined periods of time and awarded under the 2008 Plan as evidenced by an award agreement that represents a commitment to provide the Selected Participant a specific number of shares of Company common stock on one or more future dates on the defined vesting date(s). 
“RONA” shall mean the Company’s net income from continuing operations, excluding restructuring charges, divided by net assets (calculated, for the purposes of this Plan, as current assets less cash, less current liabilities plus net book value of property plant and equipment).  The final calculation of RONA is subject to one-time adjustments/exclusions 

as agreed upon by management and the Committee.
“Selected Participant” shall mean regular, full-time employees of the Company who are selected by the Committee to participate in the Plan.
“Stock Option (SO) Grant” or “SO” shall mean a grant of a non-qualified stock option under the 2008 Plan that allows the Selected Participant to purchase a specific number of shares at a pre-determined price upon the lapse of one or more defined periods of time.  
“2008 Plan” shall mean the 2008 Omnibus Incentive Plan, as amended.
ELIGIBILITY
Participation is limited to Selected Participants who are not covered by any other long-term incentive plan and are therefore eligible to participate in the Plan.
Notwithstanding anything in the Plan to the contrary, and unless otherwise determined by the Committee, an individual shall not be eligible to participate in the Plan if such individual (a) performs services for the Company and is classified or paid as an independent contractor by the Company or (b) performs services for the Company pursuant to an agreement between the Company and any other person or entity including an employee leasing organization.
To be eligible for the Plan, a Selected Participant must be actively employed by the Company in the eligible role as of January 1, 2015, and must continue to be employed and provide the services required of their position through the applicable grant/award and associated vesting dates for SOs, RSUs and PSUs. Participants who become eligible to participate in the Plan after the beginning of the Plan Term (promoted, hired, rehired or converted from a non-employee status) may be eligible for a Grants/Awards on a prorated basis. See the “New Hires / Late Entrants” section below for additional details. Participants whose tier level changes during the Plan Term (due to promotion or demotion) may be eligible, on a prorated basis, for additional Grants and Awards (in the case of promotion) or modified vesting (in case of demotions). See the “Promotions / Demotions” section below for additional details.
A Selected Participant whose employment is terminated, either voluntarily or involuntarily (regardless of cause) prior to an applicable Grant/Award or vesting date will not earn or be eligible to receive a Grant/Award or the associated vesting thereof.
Failure to comply with the Company’s policies and internal controls, including but not limited to audit and control issues, and delegation of authority, may result in a loss of eligibility and potentially termination of employment.
MEASURES OF PERFORMANCE
For the Plan Term, with respect to the PSUs, the annual performance metrics for threshold, target and stretch RONA for the Fiscal Year has been set by the Committee and the Board of Directors. 
Once established, performance metrics normally shall not be changed during the Plan Term. However, if the Committee determines that external changes, unanticipated business conditions, or significant acquisitions or dispositions have materially affected the fairness of the performance metrics, then one or more of the performance metrics may be modified during the Fiscal Year at the sole discretion of the Committee. The Committee should include a review of the corporate tax requirements should such change in performance metrics be considered.
GRANT CALCULATION 
The number of SOs, RSUs, and PSUs awarded to each Selected Participant will be based on a target annual value to be delivered to such Selected Participant based on the Selected Participant’s employment tier/title, as determined by the Committee. The target annual value for each level is as follows:

	
		
	 
	Target Annual Value

	Tier 0 (CEO)
	$1.6M

	Tier 1 (EVP CFO)
	$500,000

	Tier 1 (EVP GC)
	$400,000

	Tier 2 (SVP)
	$225,000

	Tier 3 (VP)
	$125,000

The aggregate SOs granted and RSUs and PSUs awarded would be based on the target annual value for each tier level as defined by the Committee, which would then be applied to the closing or opening stock price (or a portion thereof for SOs based on an estimated Black-Scholes value) on the grant/award date or such other date/time as determined by the Committee (with a default of the closing price on the date of grant). The Plan shall utilize SOs, RSUs, and PSUs in a targeted ratio of 50% SOs, 25% RSUs and 25% PSUs. The Committee shall establish the value of a SOs utilizing an estimated Black Scholes valuation methodology that is based the volatility, risk free rate and expected term analysis.  Likewise, the Committee shall establish a value of a RSU and PSU using a valuation methodology as determined by the Committee.
PSU Awards
The Committee shall award PSUs under the Plan at the full stretch amount (200% of target) given the performance nature of the award.  While the Award of each PSU is issued on the award date as determined by the Committee, only after the Committee has confirmed that the applicable performance metric has been met for the   Fiscal Year, will the Plan grant and vest shares underlying the PSU awards or settle by the delivery of cash (or a combination thereof as determined by the Committee). If settled in whole or part in cash, the amount of cash would be equal to the closing or opening market value of shares on such settlement date or such other date/time as determined by the Committee.  See “Vesting Schedule” section below for additional details.
VESTING SCHEDULE
Unless a separate vesting schedule is established by the Committee for a Selected Participant, all SOs granted and RSUs Awarded under the Plan will vest ratably over a three (3) year period, with one-third vesting on each anniversary date of the date of the Grant/Award.  
As soon as practicable following the end of the Fiscal Year, the Company and the Committee will evaluate actual business results against the established performance metric for the Fiscal Year in order to determine the percentage of the PSU Grant that is eligible to vest and the percentage of the underlying shares related to such PSU to be granted and vested; provided, however, that with respect to the CEO, the Board shall be consulted prior to any final determination.
The percentage of shares underlying a PSU that are vested under the Plan may vary above or below the target level based on achievement of RONA returns ranging from 50% up to 200% of the annual target value.
	
		
	Actual Fiscal Year RONA Performance
	Percentage of Target Shares Vesting under PSU

	Performance At Threshold
	50%

	Performance Equal to Target
	100%

	Performance At or Above Stretch Target
	200%

Vesting percentages between the threshold and target and between target and stretch levels will be interpolated based on actual RONA results to calculate the final vesting percentage.

NEW HIRES / LATE ENTRANTS
Participants who become eligible to participate in the Plan after the beginning of the Plan Term (promoted, hired, rehired or converted from a non-employee status) will be eligible for a Grant/Award on a prorated basis. Late entrants into the Plan are subject to approval by the Committee. The actual number of SOs to be granted and RSUs or PSUs to be awarded will be prorated based on the calendar date the Selected Participant became eligible to participate during the Plan Term (“Eligibility Date”). The date the Committee approves a Selected Participant’s eligibility is considered their “Eligibility Date” for purposes of determining the timing and number of SOs, RSUs, or PSUs.

	
		
	Eligibility Date
	2015 Fiscal Year

	January 1, 2015
	100%

	April 1, 2015
	75%

	July 1, 2015
	50%

	October 1, 2015
	25%

Final eligibility percentages will be interpolated based on actual “Eligibility Date” to calculate the final number of SOs to be granted and PSUs and RSUs to be awarded. A Selected Participant who becomes eligible after October 1 of the Fiscal Year will not be eligible for a Grant/Award.
PROMOTIONS / DEMOTIONS
The promotion of a Selected Participant shall be indicated by an approved change in tier/title level from one eligible level to another (for example, a promotion from Tier 3 to Tier 2). See “New Hires/Late Entrants” section for the treatment of individuals whose promotion results in new eligibility in the Plan (for example, a promotion from an ineligible level (tier 4 and below) to an eligible one). The Committee may in its sole and absolute discretion determine that a promotion is not entitled to an increase in Grants or Awards.
Upon approval of the promotion by the Company and, for purposes of this Plan, confirmed by the Committee, the Selected Participant may be eligible for an additional Grant of SOs or Award of RSUs or PSUs by the Committee representing the difference in targeted value between the old and new tier levels for the remainder of the Plan Term. The number of additional SOs, RSUs PSUs to be Granted/Awarded will be prorated based on the actual promotion date for the calendar year in which the promotion occurs.
A demotion of a Selected Participant shall be determined by the Company, and such action would result in a change in tier level from one eligible level to the level below (e.g., a demotion from Tier 2 to Tier 3). Any vesting that occurs following the demotion will be based upon the new level for the remainder of the Plan Term. The number of SOs, RSUs or PSUs available for vesting or settlement will be prorated based on the actual demotion date. If the demotion occurs following the end of the Fiscal Year, but prior to the vesting or settlement of SOs, RSUs or PSUs for the Fiscal Year (e.g., a demotion effective in January or early February), the Selected Participant will be eligible for the vesting/settlement at the prior tier level for the prior Fiscal Year and prorated based on the new level for the remainder of the Plan Term.
If the demotion results in the loss of eligibility in the Plan (e.g., a demotion from Tier 2 or 3 to Tier 4 or below), the Selected Participant will not be eligible for further vesting/settlement under the Plan. All unvested SOs granted and PSUs or RSUs awarded under the Plan will be cancelled as of the demotion date in the above example.
TERMINATION OF EMPLOYMENT
A condition precedent to receiving a Grant of a SO or Award of a RSU or PSU and the associated vesting and settlement, or prorated portion thereof, is continuous active employment, which shall include qualifying leaves of absence through the applicable vesting of SOs and settlement of RSUs or PSUs. Participants must be actively 

employed by the Company on the date of Grant of SOs, Award of RSUs or PSUs, vesting of SOs and settlement of RSUs or PSUs in order to receive any benefit therefrom. A Selected Participant whose employment is terminated, either voluntarily or involuntarily (regardless of cause) prior to an applicable Grant, Award, vesting or settlement date will not be eligible for any Grant, Award, vesting or settlement. All unvested SOs and unsettled RSUs or PSUs are cancelled as of the employment termination date, except as provided below. Please note that irrespective of the terms of this Plan, if the Selected Participant is subject to a Company-issued executive change of control agreement (“CIC Agreements”), those terms may take precedence in particular situations related to certain terminations and associated vesting of SOs and settlement of RSUs or PSUs.
In addition, all vested and unvested SOs, RSUs or PSUs of a Selected Participant whose employment is terminated with cause (e.g., a violation of Company policy) is subject to cancellation and forfeiture. 
2008 OMNIBUS INCENTIVE PLAN
Grants and Awards made under this Plan must be in accordance with and are subject to the terms of the 2008 Plan. Each Selected Participant is also required to sign or electronically acknowledge the appropriate grant and award agreements agreeing to the detailed terms and conditions of the Grant and Award. These agreements will be made available to Selected Participants at the time of Grant or Award.
ADMINISTRATION
The Committee will be responsible for the administration of the Plan. The Committee is authorized to interpret the Plan, to prescribe, amend, and rescind rules and regulations deemed advisable, and to make all other administrative determinations necessary. Any decision of the Committee in the interpretation and administration of the Plan, as described herein, shall lie within its sole and absolute discretion and shall be final, conclusive and binding on all parties concerned.
GENERAL
The Committee reserves the right to define Company performance metrics and to review, revise, amend, or terminate the Plan at any time without notice at its sole discretion without any liability to the Selected Participant.  Only the Committee has the ability to modify the Plan, and all modifications to the Plan must be in writing and approved by the Committee, and all modifications to the Plan related to the CEO must be reviewed by the Board of Directors. Except for certain limited exceptions with respect to CIC Agreements (as discussed above), this Plan document supersedes any previous document you may have received.
The Company shall not be required to fund or otherwise segregate any cash or any other assets which may at any time be paid to Selected Participants under the Plan. The Plan shall constitute an “unfunded” plan of the Company.
In the event of any conflict between a Selected Participant’s employment agreement with the Company and this Plan, the terms of the Selected Participant’s employment agreement will control for those provisions that do not relate to equity incentive compensation.
The provisions contained in this Plan set forth the entire understanding of the Company with respect to the Plan and supersedes any and all prior communications between the Company and any employee with respect to the Plan.
In the event any provision of the Plan shall be held illegal or invalid for any reason, the illegality or invalidity shall not affect the remaining parts of the Plan, and the Plan shall be construed and enforced as if the illegal or invalid provision had not been included.
Any questions regarding this Plan should be directed to the Human Resources department.
