EMPLOYMENT AGREEMENT (Executive Chair)

Exhibit 10.13

EMPLOYMENT AGREEMENT

(Executive Chair)

This Employment Agreement (the "Agreement"), is made effective at the Effective Date set forth below, between Heska Corporation, a Delaware corporation ("Heska" or the "Company") and Xxxxxx X. Xxxxxx, Ph.D. ("Executive").

RECITALS

Executive is currently the Chair ("Chair") of Heska Board of Directors (the "Board'), and Chief Executive Officer ("CEO") of Heska. Executive and Heska entered into an employment agreement dated March 29, 2006 and amended January 1, 2008 (the "Prior Agreement").

In furtherance of the Board’s succession planning for Heska's executive team, the Board desires to separate the positions of Chair and CEO, appoint a new CEO and continue the employment of Executive in a new role ("Executive Chair"), on the terms and conditions set forth below and with specific title to be determined by the Board as appropriate from time to time.

The Board has determined to nominate Executive for election to a three-year term as a Board member at the Company's upcoming Annual Meeting of Stockholders in May 2014 (the "2014 Election"). If Executive is not elected to the Board at the 2014 Election or if Executive's term on the Board ends prior to the Termination Date, as defined below, Executive will perform his duties hereunder as an executive officer and employee of the Company on the terms and conditions of this Agreement. Executive will continue to serve as Chair of the Board of the Company upon execution and delivery of this Agreement, subject to the discretion of the Corporate Governance Committee of the Board and the Board.

Executive and Heska now wish to replace the Prior Agreement and enter into this Agreement regarding the terms of Executive's employment, which shall become effective upon execution and delivery of this Agreement (the "Effective Date").

AGREEMENT

In consideration of the promises, covenants and agreements set forth below, it is mutually agreed:

1. Duties and Scope of Employment.

(a) Position and Duties. Executive shall continue to serve as CEO until immediately following the filing of Heska's Form 10-K for the fiscal year ended December 31, 2013 with the Securities and Exchange Commission, after which time Executive will serve as Executive Chair of Heska; provided, that if Executive is not serving as a member of the Board at any time during the Term of Agreement (defined below), Executive will perform his duties hereunder in the capacity of an executive officer and employee with such appropriate title as the Board shall designate for him. The period of Executive’s employment under this Agreement is referred to herein as the "Term of Agreement." Initially, Executive will have primary executive

responsibility for corporate governance and investor relations; provided, that if Executive is not serving as a member of the Board, Executive's primary executive responsibility will be investor relations and board service on Company majority- or wholly-owned subsidiaries. In consultation with the Board, Executive will actively transition certain responsibilities to the CEO over the Term of Agreement. The Board may, in its discretion and in consultation with Executive, further change or reduce Executive's duties during the Term of Agreement to facilitate the transition of responsibilities to the CEO; provided, that the Board may not assign additional duties, or non-executive duties, to Executive without his written consent. Throughout the Term of Agreement, Executive will report to the Board and not to any other executive officer.

(b) Board Membership. The Board has agreed to nominate Executive for election to a three-year term as a Board member of the Company at the 2014 Election. Executive's service as a member of the Board will be subject to any required stockholder approval. Executive's continuing service as Chair will be subject to the discretion of the Corporate Governance Committee and the Board, and any decision of the Board to consolidate the positions of CEO and Chair in another individual or change Executive's title will not affect or trigger any other provision of this Agreement. Executive is being compensated for Board service under this Agreement, whether as Chair or not and regardless of any other responsibilities under this Agreement, and shall not be entitled to any additional compensation beyond that provided in this Agreement for Board service through the Termination Date.

(c) Obligations. During the Term of Agreement, Executive will devote such of Executive's business efforts and time to Heska as Executive shall reasonably determine are required to carry out his duties, it being understood that the role of Executive Chair is not intended to be full time. For the duration of the Term of Agreement, Executive agrees not to actively engage in any other employment, occupation or consulting activity for any direct or indirect remuneration without the prior approval of the Board or the Corporate Governance Committee of the Board (which approval will not be unreasonably withheld); provided, however, that Executive may, without the approval of the Board or the Corporate Governance Committee, (i) serve for remuneration as an outside director or advisor to other companies not engaged in Competition (as defined in Section 9) with Heska and (ii) serve in any capacity with any civic, educational or charitable organization; provided in the case of (i) and (ii) that such services do not interfere with Executive's obligations to Heska.

(d) At-Will Employment. Subject to the provisions of Sections 3, 4, 7, 8, and 9 below, Executive and Heska agree that Executive's employment constitutes "at-will" employment. Executive and Heska acknowledge that this employment relationship may be terminated at any time, upon written notice to the other party (which in the case of Heska will mean the Board), with or without good cause or for any or no cause, at the option either of Heska or Executive. However, as described in this Agreement, Executive may be entitled to severance benefits depending upon the circumstances of Executive's termination of employment. In the event Heska terminates Executive's employment for "Cause" as defined in Section 9(b) below, such written notice shall detail the reasons for termination. Upon the termination of Executive's employment for any reason, and without diminution, Executive will be entitled to payment of all accrued but unpaid compensation, expense reimbursements, and other benefits due to Executive through Executive's last date of employment with the Company under any Company-provided or paid plans, policies, and arrangements. Executive agrees to resign from all positions that he holds

with Heska, including, without limitation, his position as a member of the Board, immediately following the termination of his employment if the Board so requests.

2. Term of Agreement. Subject to the provisions for earlier termination in Sections 1(d), 7, 8, and 9 of this Agreement, this Agreement will have a term commencing on the Effective Date and ending on April 30, 2017 (the "Termination Date").

3. Exchange of Contract Rights; Compensation.

(a) The Parties acknowledge that pursuant to the Prior Agreement, the diminishment of Executive's duties as CEO contemplated by this Agreement entitles Executive to terminate his employment for "Good Reason" (as defined therein) and receive certain severance payments, benefits and accelerated vesting of equity awards as set forth therein (collectively, the "CEO Transition Benefits"). To induce Executive to exchange the CEO Transition Benefits for the good and valuable consideration set forth in this Agreement (including but not limited to the covenants set forth in Sections 8(b) and (c) of this Agreement), Heska hereby agrees to compensate Executive as follows (the "Exchange Compensation"):

(i) Heska shall pay Executive a one-time payment of ($475,000) in cash, subject to required withholding, on the Termination Date (the "Termination Payment"); and

(ii) Upon execution and delivery of this Agreement, Heska shall grant to Executive that number of shares (the "Transition Award") of the Company's Common Stock determined by dividing $350,000 by the closing price per share of the Company's Common Stock reported by Nasdaq Capital Market on the trading day immediately prior to the Effective Date or, if no closing price is so reported for that date, the closing price on the next preceding date for which a closing price was reported (the “Closing Price”), which shall be issued as shares of Restricted Stock in accordance with 2003 Equity Incentive Plan and the 1997 Stock Incentive Plan, respectively (together, the "Plan") and pursuant to the terms and conditions of the form of Restricted Stock Award Agreement attached hereto as Exhibit A (the "Award Agreement"), which shall provide that the Transition Award will vest in full on the Termination Date.

(b) In consideration of the Exchange Compensation and this Agreement, Executive hereby agrees that the Prior Agreement is superseded in its entirety by this Agreement, and all obligations of Heska under the Prior Agreement, including but not limited to the CEO Transition Benefits, are hereby deemed satisfied in their entirety, and Executive shall no longer have any rights to, or interest in, the CEO Transition Benefits.

4. Cash Compensation; Equity.

(a) Base Salary. During the Term of Agreement, Heska will pay Executive a monthly salary as compensation for his services (the "Base Salary") as follows:

(ii) May 1, 2014 through April 30, 2015: $27,750

(iii) May 1, 2015 through April 30, 2016: $24,500

(iv) May 1, 2016 through the Termination Date: $21,000

The Base Salary will be paid periodically in accordance with Heska's normal payroll practices and be subject to the usual, required withholding. Executive's salary will be subject to review, and adjustments may be made by the Compensation Committee of the Board (the "Committee") in its discretion; provided, that the Base Salary shall not be reduced without Executive's written consent.

(b) Bonus Plan Provisions. From the Effective Date through December 31, 2014, Executive will be eligible to participate in the Management Incentive Plan (the "Bonus Plan"), or such other bonus programs as established by the Committee, at a target percentage that is no less than the following percentages of Executive's annual base salary then in effect (the "2014 Bonus"):

(i) January 1, 2014 through April 30, 2014: 50%

(ii) May 1, 2014 through December 31, 2014: 35%

The actual bonus paid may be higher or lower than the target 2014 Bonus for over or under-achievement of Executive's performance goals, as determined by the Committee. The 2014 Bonus, if any, will accrue and become payable in accordance with the Committee's standard practices for paying executive incentive compensation, provided however that any bonus payable under this Section 4(b) will be payable within two-and-one-half months after the end of the taxable year to which it relates or such longer period as may be permitted by Treasury regulations in order to avoid application of Section 409A of the Code to such bonuses. Executive shall not be eligible to participate in the Bonus Plan after December 31, 2014 and in lieu thereof, upon execution and delivery of this Agreement, Heska shall:

(i) in lieu of eligibility for a bonus under the Bonus Plan in 2015, grant to Executive that number of shares of the Company's Common Stock determined by dividing $50,000 by the Closing Price (the "First In-Lieu Award"), which shall be issued as shares of Restricted Stock in accordance with the Plan and pursuant to the terms and conditions of the Award Agreement, which shall provide that the First In-Lieu Award will vest in full on the Termination Date; and

(ii) in lieu of eligibility for a bonus under the Bonus Plan in 2016 and 2017, grant to Executive that number of shares of the Company's Common Stock determined by dividing $25,000 by the Closing Price (the "Second In-Lieu Award"), which shall be issued as shares of Restricted Stock in accordance with the Plan and pursuant to the terms and conditions of the Award Agreement, which shall provide that the Second In-Lieu Award will vest in full on the Termination Date.

(c) Eligibility for Equity Grants. During the Term of Agreement, Executive will not be eligible to receive periodic equity grants normally made to executives of the Company in the discretion of the Committee from time to time ("Periodic Equity Grants");

provided, that the Committee will have the authority, but not an obligation, to consider equity grants to Executive in special circumstances. In lieu of eligibility for Periodic Equity Grants, upon execution and delivery of this Agreement, Heska shall grant to Executive 15,000 shares of the Company's Common Stock (the "Third In-Lieu Award"), which shall be issued as shares of Restricted Stock in accordance with the Plan and pursuant to the terms and conditions of the Award Agreement, which shall provide that the Third In-Lieu Award will vest in full on the Termination Date.

5. Expenses. In addition to the foregoing, Heska will reimburse Executive for his reasonable out-of-pocket travel, entertainment, and other expenses, in accordance with Heska's expense reimbursement policies as in effect from time to time.

6. Employee Benefits. During the Term of Agreement, Executive will be eligible to participate in accordance with the terms of all Heska health and other employee benefit plans, policies, and arrangements that are applicable to other senior executives of Heska, as such plans, policies, and arrangements may exist from time to time. Upon termination of this Agreement, the Company will transfer to Executive any life insurance or disability insurance policies on Executive then maintained by the Company, subject to the consent of the issuers of such policies; and provided, that all costs of such transfers and post-termination premiums shall be paid by Executive.

7. Severance.

(a) Termination without Cause or for Good Reason. If Executive's employment is terminated by Heska (or by Heska's successor following a Change of Control) without Cause, or by Executive for Good Reason, or is terminated due to the death or Disability (as defined in Section 9(e) below) of Executive, Executive will receive, subject to Section 8 and required withholding:

(i) Accelerated payment of the Termination Payment within ten (10) days after his separation date (the "Separation Date");

(iv) If the Separation Date occurs before December 31, 2014, a bonus, if any, that would have been received under the terms of Section 4(b) above, but pro-rated for the period beginning on January 1, 2014 and ending on the Separation Date, to be paid to Executive in the next fiscal year on the earlier of (A) March 15 or (B)such earlier date on which payments are made to other participants in the Bonus Plan; and

(c) 409A Limitations. If Executive is a "specified employee" within the meaning of Section 1.409A-1(i) of the Treasury regulations as of the date of termination, then payments to Executive under this Section 7 shall not be made before the date that is six months after the date of termination (or if earlier, the date of death of Executive); provided, however, that during such six-month period, Heska shall make any and all payments contemplated hereunder to the extent such payments do not exceed two times the lesser of (i) Executive’s annualized compensation, based upon the annual rate of compensation for the calendar year preceding the year in which the date of termination occurs, or (ii) the maximum amount that may be taken into account under a qualified plan pursuant to Section 401(a)(17) of the Code for the year in which the date of termination occurs; and provided further that any amounts deferred hereunder shall be paid in a lump-sum amount at the expiration of such six-month period. It is the parties' intent that no payment made or to be made hereunder shall be subject to the provisions of Section 409A(a)(1)(B) of the Internal Revenue Code of 1986, as amended (the "Code"). Accordingly, notwithstanding any payment date or schedule specified above, the parties agree to work expeditiously to amend this Agreement to conform to their intent as set forth in this Section 7(c).

(d) Excise Tax. In the event that any payments or benefits payable to Executive pursuant to this Agreement ("Termination Benefits") (i) constitute "parachute payments" within the meaning of Section 280G of the Code, or any comparable successor provisions, and (ii) but for this Section 7(d) would be subject to the excise tax imposed by

Section 4999 of the Code, or any comparable successor provisions (the "Excise Tax"), then Executive's Termination Benefits hereunder shall be either (a) provided to Executive in full, or (b) provided to Executive as to such lesser extent which would result in no portion of such benefits being subject to the Excise Tax, whichever of the foregoing amounts, when taking into account applicable federal, state, local and foreign income and employment taxes, the Excise Tax, and any other applicable taxes, results in the receipt by Executive, on an after-tax basis, of the greatest amount of benefits, notwithstanding that all or some portion of such benefits may be taxable under the Excise Tax. Unless the Company and Executive otherwise agree in writing, any determination required under this Section 7(d) shall be made in writing in good faith by the Company's independent accountants. In the event of a reduction of benefits hereunder, Executive shall be given the choice of which benefits to reduce. If Executive does not provide written identification to the Company of which benefits he chooses to reduce within ten (10) days after written notice of the accountants’ determination, and Executive has not disputed the accountants’ determination, then the Company shall select the benefits to be reduced. For purposes of making the calculations required by this Section 7(d), the accountants may make reasonable assumptions and approximations concerning applicable taxes and may rely on reasonable, good faith interpretations concerning the application of the Code, and other applicable legal authority. The Company and Executive shall furnish to the accountants such information and documents as the Accountants may reasonably request in order to make a determination under this Section 7(d). The Company shall bear all costs the accountants may reasonably incur in connection with any calculations contemplated by this Section 7(d).

8. Conditions to Receipt of Severance; Covenants; No Duty to Mitigate.

(a) Separation Agreement and Release of Claims. The receipt of any payments or benefits pursuant to Section 7 will be subject to Executive signing and not revoking a separation agreement and release of claims in the form attached hereto as Exhibit B.

(b) Non-Competition. Executive agrees not to engage in Competition (as defined below), during the Term of Agreement and for 12 months following Executive's last date of employment with the Company, anywhere in the United States of America. If Executive engages in Competition within such period in such geographic scope, all continuing payments and benefits to which Executive otherwise may be entitled pursuant to Section 7 will cease immediately. In addition to the remedy specified in the preceding sentence, the Company will have against Executive in the event of his breach of this Section 8(b) any and all remedies available to it in law or in equity, including without limitation the right to seek recovery of any amounts paid under Section 7 of this Agreement.

(c) Nonsolicitation. Executive agrees that, during the Term of Agreement and for 24 months following Executive's last date of employment with the Company, Executive, directly or indirectly, whether as employee, owner, sole proprietor, partner, director, member, consultant, agent, founder, co-venturer or otherwise, will not (i) solicit, induce, or influence any

person to modify his or her employment or consulting relationship with the Company (the "No-Inducement"), or (ii) anywhere in the United States of America, intentionally divert business away from the Company by soliciting business from any of the Company's substantial customers and users who would otherwise have placed the solicited order with the Company (the "No Solicit"). If Executive breaches the No-Inducement or No Solicit, all continuing payments and benefits to which Executive otherwise may be entitled pursuant to Section 7 will cease immediately. In addition to the remedy specified in the preceding sentence, the Company will have against Executive in the event of his breach of this Section 8(c) any and all remedies available to it in law or in equity, including without limitation the right to seek recovery of any amounts paid under Section 7 of this Agreement.

This Agreement, together with that certain Consulting Agreement entered between Heska and Executive contemporaneously with this Agreement, the Confidentiality Agreement, Heska's stock plans, and Executive's stock option and restricted stock agreements, represents the entire agreement and understanding between the parties as to the subject matter herein and supersedes all prior or contemporaneous agreements whether written or oral, including the Prior Agreement. No waiver, alteration, or modification of any of the provisions of this Agreement will be binding unless in a writing that specifically references this Section and is signed by duly authorized representatives of the parties hereto.

15. Interpretation. Section titles and headings contained herein are inserted for convenience of reference only and are not intended to be a part of or to affect the meaning or interpretation of this Agreement.

17. Waivers. Any term or provision of this Agreement may be waived, or the time for its performance may be extended, by the party or parties entitled to the benefit thereof. Any such waiver shall be validly and sufficiently authorized for the purposes of this Agreement if, as to any party, it is authorized in writing by an authorized representative of such party. The failure of any party hereto to enforce at any time any provision of this Agreement shall not be construed to be a waiver of such provision, nor in any way to affect the validity of this Agreement or any part hereof or the right of any party thereafter to enforce each and every such provision. No waiver of any breach of this Agreement shall be held to constitute a waiver of any other or subsequent breach.

18. Partial Invalidity. Wherever possible, each provision hereof shall be interpreted in such manner as to be effective and valid under applicable law, but in case any one or more of the provisions contained herein shall, for any reason, be held to be invalid, illegal or unenforceable in any respect, such provision shall be ineffective to the extent, but only to the extent, of such invalidity, illegality or unenforceability without invalidating the remainder of such invalid, illegal or unenforceable provision or provisions or any other provisions hereof, unless such a construction would be unreasonable. The parties agree that an arbitrator or court of competent jurisdiction shall reform any invalid, illegal, or unenforceable provisions to ensure such provisions are effective and valid under applicable law.

19. Tax Matters.

(a) Except as provided in paragraph 7(d) above, Executive agrees that he is responsible for any applicable taxes of any nature (including any penalties or interest that may apply to such taxes) that are reasonably determined to apply to any payment made to Executive hereunder (or any arrangement contemplated hereunder), that Executive's receipt of any benefit hereunder is conditioned on his satisfaction of any applicable withholding or similar obligations that apply to such benefit, and that any cash payment owed to Executive hereunder will be

reduced to satisfy any such withholding or similar obligations that may apply thereto. Executive and Heska agree to cooperate to make such amendments to the terms of this Agreement as may be necessary to avoid the imposition of penalties and additional taxes under Section 409A of the Code; provided, however, that no such amendment shall materially increase the cost to, or impose any liability on, Heska with respect to any benefits contemplated or provided hereunder. To the extent that any right to reimbursement of expenses or payment of any benefit in-kind under this Agreement constitutes nonqualified deferred compensation (within the meaning of Section 409A of the Code), (i) any such expense reimbursement shall be made by Heska no later than the last day of the taxable year following the taxable year in which such expense was incurred by Executive, (ii) the right to reimbursement or in-kind benefits shall not be subject to liquidation or exchange for another benefit, and (iii) the amount of expenses eligible for reimbursement or in-kind benefits provided during any taxable year shall not affect the expenses eligible for reimbursement or in-kind benefits to be provided in any other taxable year; provided that the foregoing clause shall not be violated with regard to expenses reimbursed under any arrangement covered by Section 105(b) of the Code solely because such expenses are subject to a limit related to the period the arrangement is in effect.

(b) Executive acknowledges that under Section 83 of the Code, as the shares of Restricted Stock granted under this Agreement (the "Shares") vest, the fair value of such Shares will be reportable as ordinary income at that time. Executive further understands that instead of being taxed when and as the Shares vest, Executive may elect to be taxed as of the date the Shares are granted to Executive, with respect to the fair value of all Shares on such date. Such election may only be made under Section 83(b) of the Code within thirty (30) days after such date of grant. Executive acknowledges that failure to make this filing within the thirty (30) day period will result in the recognition of ordinary income as the Shares vest. EXECUTIVE ACKNOWLEDGES THAT IT IS EXECUTIVE’S SOLE RESPONSIBILITY, AND NOT THE COMPANY’S, TO FILE A TIMELY ELECTION UNDER SECTION 83(b), EVEN IF EXECUTIVE REQUESTS THE COMPANY OR ITS REPRESENTATIVES TO MAKE THIS FILING ON EXECUTIVE’S BEHALF. EXECUTIVE IS RELYING SOLELY ON HIS OWN ADVISORS WITH RESPECT TO THE DECISION AS TO WHETHER OR NOT TO FILE AN 83(b) ELECTION.

(c) Executive acknowledges that no representative or agent of Heska has provided him with any tax advice of any nature, and Executive has consulted with his own legal, tax and financial advisor(s) as to tax and related matters concerning the compensation to be received under this Agreement.

20. Governing Law; Waiver of Jury Trial. THIS AGREEMENT SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE INTERNAL LAWS OF THE STATE OF COLORADO WITHOUT REGARD TO CONFLICT OF LAW PRINCIPLES. THE PARTIES HERETO EACH WAIVE THEIR RESPECTIVE RIGHTS TO A JURY TRIAL OF ANY AND ALL SUCH CLAIMS AND CAUSES OF ACTION.

21. Injunctive Relief; Arbitration; Attorneys’ Fees.

(a) The parties acknowledge and agree that a breach of Sections 8, 9, or 11 of this Agreement by Executive would result in immediate and irreparable harm to the Company. Therefore, in the event of Executive's breach of Sections 8, 9, or 11, the Company shall have any

and all remedies available to it in law or in equity, including without limitation the right to seek recovery of any amounts paid under this Agreement and injunctive relief, specific performance, or any other equitable relief to prevent a breach and to secure the enforcement of this Section. Injunctive relief may be granted immediately upon the commencement of any such action.

(b) Subject to the provisions in Section 21(a) above, if any dispute arises under this Agreement or by reason of any asserted breach of it, or from the parties' employment relationship or any other relationship, either party may elect to have the dispute resolved through arbitration. The arbitration shall be binding and conducted pursuant to the rules of the American Arbitration Association under its National Rules for the Resolution of Employment Disputes and the arbitrator shall allocate the fees and expenses of such arbitration. Regardless of whether the dispute is resolved through arbitration or litigation, the prevailing party shall be entitled to recover all costs and expenses, including reasonable attorneys' fees, incurred in enforcing or attempting to enforce any of the terms, covenants and conditions of this Agreement, including costs incurred prior to commencement of arbitration or legal action, and all costs and expenses, including reasonable attorneys’ fees, incurred in any appeal from an action brought to enforce any of the terms, covenants or conditions of this Agreement. For purposes of this section, "prevailing party" includes, without limitation, a party who agrees to dismiss a suit or proceeding upon the other's payment or performance of substantially the relief sought.

22. Survival. Notwithstanding any other provisions in this Agreement to the contrary, Sections 3, 7-15, and 17-23 shall survive the expiration or termination of this Agreement.

23. Counterparts. This Agreement may be executed in counterparts, and each counterpart will have the same force and effect as an original and will constitute an effective, binding agreement on the part of each of the undersigned.

WHEREAS, Employee's employment with the Company terminated effective (the "Termination Date");

WHEREAS, the Parties wish to resolve fully and finally any potential disputes regarding Employee's employment with the Company and any other potential disputes between the Parties; and

WHEREAS, in order to accomplish this end, the Parties are willing to enter into this Agreement.

NOW THEREFORE, in consideration of the mutual promises and undertakings contained herein, the sufficiency of which is acknowledged by the Parties, the Parties to this Agreement agree as follows:

TERMS

Effective Date. This Agreement shall become effective (the "Effective Date") on the day of Employee's execution of this Agreement, provided that Employee has not revoked Employee's acceptance pursuant to Paragraph 8.f. below. Employee's Termination Date will not change regardless of whether this Agreement becomes effective on the "Effective Date."

2.	Consideration.

Payment. Commencing after the expiration of the Effective Date, and on the express condition that Employee has not revoked this Agreement, the Company will provide the severance payments and benefits on the terms and conditions contemplated by the Employment Agreement beween the Company and Executive dated ___________, 20__.

b.	Reporting and Withholding. Reporting of and withholding on any payment under this Paragraph for tax purposes shall be at the discretion of the Company in conformance with applicable tax laws.

3.	General Release.

Employee, for Employee, and for Employee's affiliates, successors, heirs, subrogees, assigns, principals, agents, partners, employees, associates, attorneys, and representatives, voluntarily, knowingly, unequivocally, unconditionally and intentionally releases, discharges and covenants not to xxx or assert against Company any and all causes of action, whether at law or in equity (i) the Company and its predecessors, successors, parents, subsidiaries, affiliates, and assigns, and (ii) each of their respective officers, directors, principals, shareholders, agents, attorneys, board members, and employees from any and all claims, actions, liabilities, demands, rights, damages, costs, expenses, and attorneys’ fees (including, but not limited to, any claim of entitlement for attorneys' fees under any contract, statute, or rule of law allowing a prevailing party or plaintiff to recover attorneys' fees), of every kind and description from the beginning of time through the Effective Date (the "Released Claims").

The Released Claims include, but are not limited to, those which arise out of, relate to, or are based upon: (i) Employee's employment with the Company or the termination thereof; (ii) statements, acts, or omissions by the Parties whether in their individual or representative capacities; (iii) express or implied agreements between the Parties, (except as provided herein); (iv) any stock or stock option grant, agreement, or plan; (v) all federal, state, and municipal statutes, ordinances, and regulations, including, but not limited to, claims of discrimination based on race, color, national origin, age, sex, sexual orientation, religion, disability, veteran status, whistleblower status, public policy, or any other characteristic of Employee under the Age Discrimination in Employment Act, the Older Workers Benefit Protection Act, the Americans with Disabilities Act, the Equal Pay Act, Title VII of the Civil Rights Act of 1964 (as amended), the Employee Retirement Income Security Act of 1974, the Rehabilitation Act of 1973, Family and Medical Leave Act, the Worker Adjustment and Retraining Notification Act, Colorado Anti-Discrimination in Employment Act, seq, or any other federal, state, or municipal law prohibiting discrimination or termination for any reason; (vi) state and federal common law; (vii) the failure of this Agreement, or of any other employment, severance, profit sharing, bonus, equity incentive or other compensatory plan to which Employee and the Company are or were parties, to comply with, or to be operated in compliance with, Section 409A of the Internal Revenue Code of 1986, as amended ("Section 409A"), or any similar provision of state or local income tax law; and (viii) any claim which was or could have been raised by Employee.

The Agreement does not affect Employee’s right to file a charge with or participate before the Equal Employment Opportunity Commission. However, Employee agrees that in the event Employee brings a claim covered by the foregoing General Release in which Employee seeks damages or other remedies against the Company, or in the event Employee seeks to recover against the Company in any claim brought by a government agency on Employee's behalf, this Agreement shall serve as a complete defense to such claims, and that

Employee is expressly waiving the right to recover damages and attorney's fees from any such proceeding.

Return of Company Property. Employee represents and warrants that Employee returned all Company property to the designated Company representative on or before Employee's Termination Date, unless otherwise agreed upon. This property includes, but is not limited to, Company documents and files (in any recorded media, such as papers, computer disks, copies, transparencies, and microfiche), materials, keys, credit cards, laptops, computer disks, and badges. Employee agrees that, unless otherwise agreed upon in writing, to the extent that Employee possesses any files, data, or information relating in any way to the Company or the Company's business on any personal computer, Employee will delete the data, files, or information (and will retain no copies in any form).

Unknown Facts. The releases in this Agreement include, but are not limited to, claims of every nature and kind, known or unknown, suspected or unsuspected. Employee hereby acknowledges that Employee may hereafter discover facts different from, or in addition to, those which Employee now knows to be or believes to be true with respect to this Agreement, and Employee agrees that this Agreement and the releases contained herein shall be and remain effective in all respects, notwithstanding such different or additional facts or the discovery thereof.

Confidentiality of Agreement. Except as herein provided, all discussions regarding this Agreement, including, but not limited to, the amount of consideration, offers, counteroffers, or other terms or conditions of the negotiations or the agreement reached shall be kept confidential by Employee from all persons and entities other than the Parties to this Agreement. Employee may disclose such information only if necessary (a) for the limited purpose of making disclosures required by law to agents of the local, state, or federal governments; (b) for the purpose of enforcing any term of this Agreement; (c) for the purpose of obtaining legal or tax advice about the Agreement; or (d) in response to compulsory process, and only then after giving the Company immediate notice of the compulsion and affording the Company the opportunity to obtain any necessary or appropriate protective orders. Otherwise, in response to inquiries about Employee's employment and this matter, Employee shall state, "My employment with the Company has ended" and nothing more.

7.	No Admission of Liability. The Parties agree that nothing contained herein, and no action taken by any Party hereto with regard to this Agreement, shall be construed as an admission by any Party of liability or of any fact that might give rise to liability for any purpose whatsoever.
