AMENDED AND RESTATED EMPLOYMENT AGREEMENT

This Amended and Restated 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 Kevin S. Wilson ('Executive') and supersedes and replaces in its entirety that certain employment agreement dated as of March 7, 2018 between Heska and Executive (the 'Prior Agreement'). Heska and Executive collectively are referred to as the 'Parties' and individually as a 'Party.'

RECITALS

Executive is currently the Chief Executive Officer and President of Heska. Executive and Heska are parties to the Prior Agreement.

The Prior Agreement will expire by its terms on December 31, 2021 and the Board of Directors of Heska (the 'Board') desires to enter into a new agreement with Executive as Chief Executive Officer and President to replace the Prior Agreement on the terms and conditions set forth below.

Executive and Heska now wish to enter into this Agreement regarding the terms of Executive's employment, which shall become effective on June 8, 2021 (the 'Effective Date') and supersede the Prior Agreement.

NOW, THEREFORE, in consideration of the foregoing and of the mutual promises, covenants, and agreements contained herein, the legal sufficiency of which is acknowledged by the Parties, agree as follows:

TERMS

1.Duties and Scope of Employment.

(a)Position and Duties. Executive shall continue to serve as Chief Executive Officer and President of Heska. Executive will render such business and professional services in the performance of Executive's duties, consistent with Executive's position within Heska, as will reasonably be assigned to Executive by the Board.

(b)Board Membership. Executive was elected to a one-year term as a Board member at the Company's Annual Meeting of Stockholders in 2021. At each meeting of Heska's stockholders when Executive is up for Board election, Heska will nominate Executive to serve as a member of the Board. Executive's service as a member of the Board will be subject to any required stockholder approval. If elected, Executive will serve on the Board without any additional compensation. At the request of the Board, Executive will also serve on the board of directors or other governing body of any subsidiary of Heska without any additional compensation.

(c)Obligations. During the Term of Agreement (as defined below), Executive will devote all of his business efforts and time (excluding vacation, absence due to illness and similar

time off) as well as other such attention, skills, time and business efforts as are necessary to responsibly act as Chief Executive Officer and President of Heska; provided, however, that Executive may continue to perform part-time management activities for Cuattro, LLC, Cuattro Software, LLC and Cuattro Medical, LLC; provided, further, that such services do not adversely affect Executive's obligations to Heska. 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; provided, however, that Executive may, without the approval of the Board or the Corporate Governance Committee of the Board, serve in any capacity with any civic, educational or charitable organization, provided, that such services do not interfere with Executive's obligations to Heska.

2.Term of Agreement.

(a)The period of Executive's employment under this Agreement is referred to herein as the 'Term of Agreement.' Subject to the provisions for earlier termination of employment in Section 6 below, this Agreement will have an initial term commencing on the Effective Date and ending on the fourth anniversary of the Effective Date; provided, however, that on the fourth anniversary of the Effective Date and each anniversary thereafter, the Term of Agreement shall be automatically renewed for an additional one-year period unless either Heska or Executive provide notice of non-renewal of the Term of Agreement at least six months prior to such anniversary; provided, further, however, that either Heska or Executive may terminate Executive's employment immediately at any time subject to the provisions in Section 6 below.

(b)Executive may be entitled to severance benefits pursuant to Section 6 below, depending upon the circumstances of Executive's termination of employment. Upon the termination of Executive's employment for any reason, (i) Executive will be entitled to payment of all accrued but unpaid compensation, expense reimbursements, and other benefits due to Executive through Executive's termination date under any Heska-provided or paid plans, policies, and arrangements and (ii) Executive agrees to resign from all positions that Executive holds with Heska, including his position as a member of the Board.

3.Compensation.

(a)Base Salary. During the Term of Agreement, Heska will pay Executive an annual salary of $1,000,000 as compensation for Executive's services (the 'Base Salary'). The Base Salary will be paid periodically in accordance with Heska's normal payroll practices and will be subject to the usual, required withholdings and deductions. Executive's Base Salary shall not be subject to change during the Term of Agreement; provided, however, that the Compensation Committee of the Board (the 'Committee') will have the authority, but not an obligation, to consider Base Salary increases for Executive.

(b)Annual Bonus. During the Term of Agreement, Executive will be eligible to participate in the Management Incentive Plan or such other bonus programs as established by the Committee (the 'Bonus Plan'), at a target percentage that is no less than 50% of Executive's Base Salary then in effect (the 'Target Bonus'). The actual bonus paid under the Bonus Plan

2

may be higher (up to a maximum of 100% of Executive's Base Salary then in effect) or lower than the Target Bonus for over or under-achievement of Executive's performance goals, as determined by the Committee in its sole discretion. The Committee may, in its sole discretion, provide additional discretionary cash bonuses. Bonuses, 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 3(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 Internal Revenue Code of 1986 (the 'Code') to such bonuses. Any bonuses paid pursuant to this Section 3(b) will be subject to applicable withholdings and deductions.

(c)Equity Grants.

(i)In General. 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. In lieu of such entitlements to participate in the normal equity programs of the Company, Heska shall make the one-time grants to Executive set forth below.

(ii)Performance-Vesting Option Grant. On the Effective Date, Heska shall grant to Executive (the 'Option Grant') options to purchase 34,800 shares of Heska Common Stock ('Options'), in accordance with the Company's Equity Incentive Plan (the 'Plan') and pursuant to the terms and conditions of the form of Award Agreement attached hereto as Exhibit A (the 'Option Award Agreement') which shall provide that such Options will vest, subject to the terms and conditions of the Option Award Agreement, based on achievement of stock price hurdles.

(iii)Performance-Vesting Restricted Stock Grants. On the Effective Date, Heska shall grant to Executive 180,000 shares of Restricted Stock (as defined in the Plan) in accordance with the Plan and pursuant to the terms and conditions of the form of Award Agreement attached hereto as Exhibit B (the 'RSA Agreement'), which shall provide that such shares of Restricted Stock shall vest, subject to the terms and conditions of the RSA Agreement, based on Heska's achievement of revenue, gross margin and adjusted EBITDA measures, with 60,000 becoming earned if 'target' levels of each performance metric are achieved and an aggregate of 180,000 becoming earned only if 'maximum' levels of each performance metric are achieved.

4.Expenses. In addition to the foregoing and subject to Section 5 below, Heska will reimburse Executive for Executive's reasonable out-of-pocket travel, entertainment, and other expenses, in accordance with Heska's expense reimbursement policies and practices in effect at the time of the reimbursement request. Executive shall submit such requests not later than 45 days after incurring such expenses.

5.Employee Benefits. Executive will be eligible to participate in other benefits offered to other senior executives of Heska working from a home office and multiple Company locations, including any Company sponsored 401(k) or retirement plan, in accordance with (and subject to the legal limitations on) benefit plans, policies, and arrangements that may exist from time to time. As of the Effective Date, such benefits include an automobile stipend of $700 per month

3

and a general home office and communications stipend of $300 per month; provided, however, that no expense reimbursements provided for under Section 4 shall be duplicative of such stipends.

6.Termination and Severance.

(a)Termination without Cause or for Good Reason Other Than In Connection with a Change of Control. If, at any time, Executive's employment is terminated by Heska without Cause (as defined below) (and not as a result of Executive's death or Disability (as defined below)) or by Executive for Good Reason (as defined below), and the termination is not In Connection with a Change of Control (as defined below), Executive will receive the following, subject to conditions and limitations set forth in Section 7:

Executive shall notify Heska immediately upon Executive's acceptance of employment with another employer.

(b)Termination without Cause or for Good Reason In Connection with a Change of Control. If, at any time, Executive's employment is terminated by Heska without Cause (and not as a result of Executive's death or Disability) or by Executive for Good Reason, and the termination is In Connection with a Change of Control, then, subject to the limitations set forth in this Section 7, Executive will receive:

(i)A payment of an amount equal to 2.99x the sum of (A) Executive's Base Salary and (B) the Target Bonus for the year of termination, payable in a lump sum within 60 days following the Termination Date.

(ii)Provided that Executive timely elects continuation coverage under COBRA, Heska shall pay the COBRA premiums for coverage for Executive and Executive's eligible dependents under Heska's Benefit Plans (as defined below) for 36 months, or if earlier, until Executive becomes eligible for Medicare or employed by another employer and eligible for coverage under such other employer's welfare benefit plans (e.g., payments for medical COBRA

4

premiums will cease when Executive becomes eligible for another employer's medical plan); provided, however, that if Executive ceases to be eligible for COBRA (other than as a result of becoming eligible for Medicare or eligible for coverage under another employer's plan), Heska shall pay to Executive a lump sum amount equal to (A) 36 less the number of months of COBRA that have previously been provided for as of such date, multiplied by (B) the amount of the COBRA premiums paid in the final month of COBRA eligibility. Executive shall notify Heska immediately upon Executive's acceptance of employment with another employer.

(c)Termination due to Death or Disability. If, at any time, Executive's employment with Heska is terminated as a result of Executive's death or Disability, then, subject to the limitations set forth in Section 7, Executive will receive:

(i)A payment of an amount equal to a pro-rated portion of Executive's Target Bonus for the year of termination based on the number of days in such year that Executive was employed by Heska, payable in a lump sum within 60 days following the Termination Date.

(ii)Provided that Executive timely elects continuation coverage under the COBRA, Heska shall pay the COBRA premiums for coverage for Executive and Executive's eligible dependents under Heska's Benefit Plans for 24 months, or if earlier, until Executive becomes eligible for Medicare or employed by another employer and eligible for coverage under such other employer's welfare benefit plans (e.g., payments for medical COBRA premiums will cease when Executive becomes eligible for another employer's medical plan); provided, however, that if Executive ceases to be eligible for COBRA (other than as a result of becoming eligible for Medicare or eligible for coverage under another employer's plan), Heska shall pay to Executive a lump sum amount equal to (A) 24 less the number of months of COBRA that have previously been provided for as of such date, multiplied by (B) the amount of the COBRA premiums paid in the final month of COBRA eligibility. Executive shall notify Heska immediately upon Executive's acceptance of employment with another employer.

(d)Termination without Good Reason or Termination for Cause. If, at any time, Executive's employment with Heska terminates voluntarily by Executive without Good Reason or is terminated for Cause by Heska, then (i) all further vesting of Executive's outstanding equity awards will terminate immediately, (ii) all payments of compensation by Heska to Executive hereunder will terminate immediately (except as to amounts already earned), but Executive will be paid all accrued but unpaid expense reimbursements and other benefits due to Executive through the Termination Date under any Company-provided or paid plans, policies and arrangements, and (iii) Executive will not be entitled to any severance or reimbursement for COBRA premiums.

(e)Excise Tax. In the event that any benefits payable to Executive pursuant to Section 6 of 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 6(e), 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

5

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 Heska and Executive otherwise agree in writing, any determination required under this Section 6(e) shall be made in writing in good faith by Heska'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 Heska of which benefits Executive chooses to reduce within 10 days after written notice of the accountants' determination, and Executive has not disputed the accountants' determination, then Heska shall select the benefits to be reduced. For purposes of making the calculations required by this Section 6(e), 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. Heska 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 6(e). Heska shall bear all costs the accountants may reasonably incur in connection with any calculations contemplated by this Section 6(e).

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

(a)Separation Agreement and Release of Claims. The receipt of any severance payments or other benefits pursuant to Section 6 will be conditioned upon Executive signing and not revoking a confidential separation agreement and release of claims in the form attached hereto as Exhibit C with such modifications as Heska shall reasonably make from time to time to comply with applicable law. No severance will be paid or provided if the Executive's confidential separation agreement and release agreement is not signed and irrevocable within 45 days after the Executive's termination date. If Executive's date of termination and the last day of any applicable statutory revocation period could fall in two separate taxable years, regardless of when Executive actually executes and delivers the release, payments will not commence until the later taxable year.

(b)Non-Competition. Executive agrees not to engage in Competition (as defined below) during the Restricted Period (as defined below). The geographic scope of this Section 7(b) is worldwide. If Executive engages in Competition within the Restricted Period and within such geographic scope, all continuing payments and benefits to which Executive otherwise may be entitled pursuant to Section 6 will cease immediately.

(c)Non-Solicitation. Executive agrees that, during the Restricted Period, Executive, directly or indirectly, whether as employee, owner, sole proprietor, partner, director, member, consultant, agent, founder, co-venturers, or otherwise, (i) will not solicit, induce, or influence any person to modify his or her employment or consulting relationship with Heska or hire or engage any of the Company's Section 16 officers (the 'No-Inducement'), and (ii) will not intentionally divert business away from Heska by soliciting business from any of Heska's customers and users who would otherwise have placed the solicited order with Heska (the 'No Solicit'). The geographic scope of this Section 7(c) is worldwide. If Executive breaches the No-Inducement or

6

No Solicit within the Restricted Period and within such geographic scope, all continuing payments and benefits to which Executive otherwise may be entitled pursuant to Section 6 will cease immediately.

(d)Remedies. In the event of Executive's breach of Section 7(b) or 7(c), Heska shall have any and all remedies available to it in law or in equity, including the right to recover any amounts paid under Section 6 of this Agreement and injunctive relief, specific performance, or any other equitable relief to prevent a breach and to secure the enforcement of this Section 7. Injunctive relief may be granted immediately upon the commencement of any such action, and Heska need not post a bond to obtain temporary or permanent injunctive relief.

(e)No Duty to Mitigate. Executive is under no duty or requirement to mitigate the amount of any payment contemplated by this Agreement, nor will any earnings that Executive may receive from any other source reduce any such payment.

Benefit Plans do not include any other type of benefit (including financial counseling, disability, life insurance or retirement benefits). A requirement that Heska provide Executive and Executive's eligible dependents with coverage under the Benefit Plans will not be satisfied unless the coverage is no less favorable than that provided to Executive and Executive's eligible dependents immediately prior to the Termination Date.

(b)Cause. For purposes of this Agreement, 'Cause' shall mean the occurrence of one or more of the following: (i) conviction of, or entry of a plea of nolo contendere to, any felony crime (including one involving moral turpitude), or any crime which reflects so negatively on Heska to be detrimental to Heska's image or interests, or any act of fraud or dishonesty that has such equivalent or greater negative reflection upon Heska; (ii) the repeated commitment of insubordination or refusal to comply with any reasonable request of the Board related to the scope or performance of Executives duties; (iii) possession of any illegal drug on Heska premises or being under the influence of illegal drugs or abusing prescription drugs or alcohol while on Heska business, attending Heska-sponsored functions, or on Heska premises; (iv) the gross misconduct or gross negligence in the performance of Executive's responsibilities which, based upon good faith and reasonable factual investigation of the Board, demonstrates Executive's unfitness to serve; (v) material breach of Executive's obligations under this Agreement; or (vi) material breach of any fiduciary duty of Executive to Heska, which results in material damage to Heska or its business; provided, however, that if any occurrence under subsections (ii), (iv), (v), and (vi) may be cured, Heska will provide notice to Executive describing the nature of such event and Executive will thereafter have 30 days to cure such event, and if such event is cured with that 30-day period, then grounds will no longer exist for terminating Executive's employment for Cause.

7

(c)Change of Control. For purposes of this Agreement, 'Change of Control' has the meaning provided to Change in Control in the Plan.

Notwithstanding the foregoing, nothing contained in this Section 8(d) or in Section 7(b) above shall prohibit Executive from being employed or engaged following the Term of Agreement in a corporate function or senior management position (and holding commensurate equity interests) in a division of a Restricted Company, so long as such division is not in any way engaged in providing veterinary diagnostics products for the companion animal health veterinary industry or imaging diagnostics products or services for the veterinary market in the United States and Executive does not directly or indirectly provide services or assistance to any division that does provide veterinary diagnostics products for the companion animal health veterinary industry or imaging diagnostics products or services for the veterinary market in the United States.

(f)Good Reason.

(i)For purposes of this Agreement, 'Good Reason' means the occurrence of any of the following without Executive's express written consent:

(a)Executive's authority with Heska is, or Executive's duties or responsibilities as President, Chief Executive Officer and member of the board of directors of a company that is U.S.-based and publicly traded on U.S. markets are, materially diminished relative to Executive's authority, duties, and responsibilities as in effect immediately prior to such change;

(b)a material diminution in Executive's Base Salary as in effect immediately prior to such diminution; provided, that an across-the-board reduction in the base compensation and benefits of all other executive officers of Heska by the same percentage

8

amount (or under the same terms and conditions) as part of a general base compensation reduction and/or benefit reduction shall not constitute such a qualifying material diminution;

(c)a required relocation of the geographic location of Executive's principal place of employment away from Executive's home in the Beaver Creek, Colorado area

(d)any material breach by Heska of any provision of this Agreement; and

(e)any acquiring company fails to assume or be bound by the terms of this Agreement In Connection with a Change of Control.

(ii)The aforementioned occurrences shall not be deemed Good Reason unless Executive gives Heska written notice of the existence of the condition which Executive believes constitutes Good Reason (which notice must be given within 90 days of the initial existence of the condition) and such condition remains uncured for a period of 30 days after the date of such notice. An event of Good Reason shall occur automatically at the expiration of such 30-day period if the relevant condition remains uncured at such time.

(g)In Connection with a Change of Control. For purposes of this Agreement, a termination of Executive's employment with Heska is 'In Connection with a Change of Control' if Executive's employment is terminated without Cause or for Good Reason during the period beginning three months prior to a Change of Control and ending 24 months following a Change of Control.

10.Executive's Representations and Warranties. Executive represents and warrants that Executive is not a party to any other employment, non-competition, or other agreement or restriction which could interfere with the Executive's employment with Heska or Executive's or Heska's rights and obligations hereunder and that Executive's acceptance of employment with Heska and the performance of Executive's duties hereunder will not breach the provisions of any contract, agreement, or understanding to which the Executive is party or any duty owed by the Executive to any other person.

12.Successors and Assigns. This Agreement will be binding upon and inure to the benefit of (a) the heirs, executors and legal representatives of Executive upon Executive's death and (b) any Successor (as defined below) of Heska. Any such Successor of Heska will be deemed substituted for Heska under the terms of this Agreement for all purposes. For purposes of this Section 12, 'Successor' means any person, firm, corporation, or other business entity which at any time, whether by purchase, merger, or otherwise, directly or indirectly, acquires all or substantially all of the assets or business of Heska. None of the rights of Executive to receive any form of compensation payable pursuant to this Agreement may be assigned or transferred except by will or the laws of descent and distribution. Any other attempted assignment, transfer, conveyance or other disposition of Executives right to compensation or other benefits will be null and void.

13.Integration. This Agreement, together with the Confidentiality Agreement, Heska's stock plans and Executive's award 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 13 and is signed by duly authorized representatives of the Parties hereto. For the avoidance of doubt, nothing herein is intended to modify the terms of Executive's existing equity award agreements outstanding immediately prior to the Effective Date, including with respect to the vesting, acceleration and forfeiture provisions applicable to such existing equity awards described in Sections 3(c), 6(a)(iii) and 6(b)(iii) of the Prior Agreement.

14.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. Unless the context requires otherwise, all references to laws, regulations, contracts, agreements and instruments refer to such laws, regulations, contracts, agreements and instruments as they may be amended from time to time, and references to particular provisions of

10

laws or regulations include a reference to the corresponding provisions of any succeeding law or regulation. All references to 'dollars' or '$' in this Agreement refer to United States dollars. The word 'or' is not exclusive. Wherever the context so requires, the masculine gender includes the feminine or neuter, and the singular number includes the plural and conversely. All references to 'including' shall be construed as meaning 'including without limitation.' The determination of the terms of, and the drafting of, this Agreement has been by mutual agreement after negotiation, with consideration by and participation of all Parties. Accordingly, the Parties agree that rules relating to the interpretation of contracts against the drafter of any particular clause shall not apply in the case of this Agreement.

15.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.

16.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.

17.Tax Matters.

(a)Except as provided in Section 6(e) above, Executive agrees that Executive 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 Executive's satisfaction or 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.

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

11

(c)Executive acknowledges that under Section 83 of the Code, as the shares of Restricted Stock granted under this Agreement 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 such shares vest, Executive may elect to be taxed as of the date such shares are granted to Executive with respect to the fair value of all such shares on such date. Such election may only be made under Section 83(b) of the Code within 30 days after such date of grant. Executive acknowledges that failure to make this election within the 30-day period will result in the recognition or 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) OF THE CODE, 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.

18.Section 409A.

(a)This Agreement is intended to comply with Section 409A of the Code ('Section 409A') and shall be constructed accordingly. It is the intention of the Parties that payments or benefits payable under this Agreement not be subject to the additional tax or interest imposed pursuant to Section 409A. To the extent such potential payments or benefits are or could become subject to Section 409A, the Parties shall cooperate to amend this Agreement with the goal of giving Executive the economic benefits described herein in a manner that does not result in such tax or interest being imposed; 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. Executive shall, at the request of Heska, take any reasonable action (or refrain from taking any action), required to comply with any correction procedure promulgated pursuant to Section 409A.

(b)If a payment that could be made under this Agreement could be subject to additional taxes and interest under Section 409A, Heska in its sole discretion may accelerate some or all of a payment otherwise payable under the Agreement to the time at which such amount is includible in the income of Executive; provided, that such acceleration shall only be permitted to the extent permitted under Treasury Regulation § l.409A-3(j)(4)(vii) and the amount of such acceleration does not exceed the amount permitted under Treasury Regulation § l.409A-3(j)(vii).

(c)No payment to be made under this Agreement shall be made at a time earlier than that provided for in this Agreement unless such payment is (i) an acceleration of payment permitted to be made under Treasury Regulation § l .409A-3(j)(4) or (ii) a payment that would otherwise not be subject to additional taxes and interest under Section 409A.

(d)The right to each payment described in this Agreement shall be treated as a right to a series of separate payments and a separately identifiable payment for purposes of Section 409A.

12

(e)For purposes of Section 6 of this Agreement, 'termination' (or any similar term) when used in reference to Executive's employment shall mean 'separation from service' with Heska within the meaning of Section 409A(a)(2)(A)(i) of the Code and applicable administrative guidance issued thereunder, and Executive shall be considered to have terminated employment with Heska when, and only when, Executive incurs a 'separation from service' with Heska within the meaning of Section 409A(a)(2)(A)(i) of the Code and applicable administrative guidance issued thereunder.

(f)If Executive qualities as a 'specified employee' within the meaning of Section 409A(a)(2)(B)(i) of the Code and would receive any payment sooner than six months after Executive's separation from service that, absent the application of this Section 18(f), would be subject to additional tax imposed pursuant to Section 409A as a result of such status as a specified employee, then such payment shall instead be payable on the date that is the earliest of (i) six months after Executive's separation from service, (ii) Executive's death, or (iii) such other date as will not result in such payment being subject to such additional tax.

19.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 or action.

20.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.

21.Arbitration; Attorney's Fees. Subject to Section 7(d) above, if any dispute arises under this Agreement or by reason of any asserted breach or 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, 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. For purposes of this section, 'prevailing Party' includes 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 provision of this Agreement to the contrary, Section 22 of the Prior Agreement and Sections 3(c)(v) and 6 through 22 of this Agreement shall survive the expiration or termination or the Prior Agreement and this Agreement.

For the avoidance of doubt, and notwithstanding anything herein or in the Plan to the contrary, in the event that your service terminates because your status changes from Employee or Consultant to Consultant, Employee or Outside Director of the Company or a Subsidiary, as applicable, such change in status will not be treated as a termination of service for purposes of this Agreement.

b.Regular Termination. If your service as an Employee or Consultant of the Company or a Subsidiary terminates for any reason other than due to your death or Disability, this Option will expire at the close of business at Company headquarters on the date that is the

earlier of the regular expiration date of the Option or nine months after your termination date; provided, however, that if such termination is a termination without Cause (as defined in your Amended and Restated Employment Agreement with the Company dated June 8, 2021 (the 'Employment Agreement')) or a resignation by you for Good Reason (as defined in the Employment Agreement), in each case, In Connection with a Change of Control (as defined in the Employment Agreement), then this Option will instead expire at the close of business at Company headquarters on the date that is the earlier of the regular expiration date of the Option or 12 months after your termination date.

(iii)Unless you immediately return to active work when the approved leave ends, your service will terminate.

SECTION 4.EXERCISE.

a.Restrictions on Exercise. The Company will not permit you to exercise this Option if the issuance of shares at that time would violate any law or regulation.

b.Notice of Exercise. When you wish to exercise this Option, you must notify the Company by filing the proper 'Notice of Exercise' form at the address given on the form. Your Notice of Exercise must specify how many Common Shares you wish to purchase pursuant to the Option.

If someone else wants to exercise this Option after your death, that person must prove to the Company's satisfaction that he or she is entitled to do so.

2

c.Method of Exercise and Payment. When you submit your Notice of Exercise, you must include payment of the Exercise Price for the Common Shares you are purchasing. Payment may be made in one (or a combination of two or more) of the following forms:

(i)your personal check, a cashier's check or a money order;

(ii)certificates for Common Shares that you already own, along with any forms needed to effect a transfer of those Common Shares to the Company. The value of the Common Shares, determined as of the effective date of the Option exercise, will be applied to the Exercise Price; provided, however, you may not surrender Common Shares in payment of the Exercise Price if your action would cause the Company to recognize compensation expense (or additional compensation expense) with respect to this Option for financial reporting purposes; or

(iii)by net exercise or broker's cashless exercise procedure, or any other procedures approved by the Committee from time to time.

d.Withholding Taxes and Stock Withholding (For Employees Only). Whenever Common Shares are to be issued pursuant to the exercise of any portion of the Option, the Company or an Affiliate thereof shall, in accordance with Article 15 of the Plan, have the power to withhold, or to require you to remit to the Company or such Affiliate thereof, an amount sufficient to satisfy any federal, state, and local withholding tax requirements, both domestic and foreign, relating to such transaction, and the Company or such Affiliate thereof may defer issuance of the Common Shares until such requirements are satisfied; provided, however, that such amount may not exceed the maximum statutory withholding rate. You will be entitled to satisfy the amount of any such required withholding by having the Company withhold from the Common Shares otherwise issuable upon exercise of the Option a number of Common Shares having a Fair Market Value equal to the amount of such required tax withholdings.

e.Delivery of Common Shares Upon Exercise. As soon as practicable after receipt of the Notice of Exercise and payment in full of the Exercise Price and any applicable taxes and withholdings with respect to any exercisable portion of the Option, but subject to the transfer restrictions set forth herein, the Company will deliver to you (or such other person or entity entitled to exercise this Option) a certificate, certificates or electronic book-entry notation representing the Common Shares acquired upon the exercise thereof, registered in your name (or such other person or entity); provided, that, if the Company, in its sole discretion, determines that, under applicable securities laws, any certificates issued hereunder must bear a legend restricting the transfer of such Common Shares, such certificates shall bear the appropriate legend.

SECTION 5.RESTRICTIONS ON RESALE.

By signing this Agreement, you agree not to sell any Common Shares at a time when applicable laws, Company policies or an agreement between the Company and its underwriters prohibit a sale. This restriction will apply as long as you are in service with the Company or a Subsidiary (whether as an Employee, Consultant or Outside Director).

3

SECTION 6.TRANSFER OF OPTION.

Prior to your death, only you may exercise this Option. You cannot transfer or assign this Option. For instance, you may not sell this Option or use it as security for a loan. You may, however, dispose of this Option in your will, by the laws of descent and distribution or through a beneficiary designation. Regardless of any marital property settlement agreement, the Company is not obligated to honor a Notice of Exercise from your former spouse, nor is the Company obligated to recognize your former spouse's interest in your Option in any other way.

SECTION 7.MISCELLANEOUS.

a.No Retention Rights. Neither this Option nor this Agreement gives you the right to be employed or otherwise retained by the Company or a Subsidiary in any capacity. The Company or a Subsidiary reserves the right to terminate your service at any time and for any reason or no reason, with or without Cause.

f.Restatement. Notwithstanding any provision of this Agreement to the contrary, this Option shall be subject to the terms and conditions of this Section 7.6 in the event that the Company issues a restatement of its audited financial statements (a 'Restatement') after any portion of this Option has vested. If any portion of this Option vests and within three years thereafter the Company issues a Restatement, and the Committee determines in its good faith discretion, based on a reasonable estimate of the effect of the Restatement, that there is a reasonable likelihood that the applicable stock price threshold would not have occurred if the results reported in the Restatement had been reported initially, then the corresponding portions of this Option shall be deemed not to have vested. If any portion of this Option is deemed not to have vested pursuant to the foregoing sentence (an 'Unearned Grant') and any portion of the Unearned Grant has been exercised for Common Shares, then you shall either (x) promptly return the Common Shares received upon exercise of the Unearned Grant to the Company or (y) if you have sold such Common Shares, pay to the Company within one year from the date of the corresponding Restatement an amount equal to the proceeds you received from any sale of such

4

Common Shares not returned by you pursuant to the foregoing clause (x). For the avoidance of doubt, if any portion of this Option is deemed not to have vested as a result of a Restatement in accordance with this Section 7.6, such unvested portion will remain eligible for vesting on the terms and conditions of this Agreement for the remainder of the vesting periods set forth herein. In addition to the foregoing, your compensation and equity awards shall remain subject to any applicable law (including, without limitation, Section 302 of the United States Sarbanes-Oxley Act and Section 954 of the United States Dodd-Frank Act) or regulation in effect from time to time.

In consideration of the mutual covenants and representations herein set forth, the Company and Executive agree as follows:

SECTION 1.GRANT OF RESTRICTED STOCK.

a.Precedence of Plan.

b.Grant of Restricted Stock. The Company hereby grants to Executive an aggregate of 180,000 Restricted Shares (the 'Shares'), subject to vesting as provided in Section 2, which will only be earned upon achievement of the 'maximum' levels of each performance metric. If only 'target' levels of each performance metric are achieved, only 60,000 will be earned.

SECTION 2.UNVESTED SHARES SUBJECT TO FORFEITURE.

a.Shares Subject to Forfeiture. The Shares are subject to vesting requirements.

a. The Shares will vest in accordance with the Vesting Schedule attached as Attachment 1.

In the event that Executive's employment with the Company is terminated following the Grant Date because of either (i) Executive's death, (ii) Executive's Disability, (iii) a termination by the Company without Cause (as defined in that certain Amended and Restated Employment Agreement by and between the Company and Executive dated June 8, 2021 (the 'Employment Agreement'), or (iv) a termination by Executive for Good Reason (as defined in the Employment Agreement), the performance metrics set forth in the Vesting Schedule will be measured as of the date of such termination using linear interpolation between each level of each performance metric (threshold, low target, target and maximum) to determine the Shares, if any, that vest as of the date of such termination. For purposes of this Section 2.1(c), if complete fiscal year data is not available as of the date of such termination, the Committee will determine performance through the date of such termination based on the partial fiscal year results notwithstanding the measurement on each Reporting Date in the Vesting Schedule attached as Attachment 1.

b.Restriction on Transfer. Until the Shares are vested, the Shares may not be sold, transferred, pledged, assigned, or otherwise alienated or hypothecated.

SECTION 3.DELIVERY OF COMMON SHARES.

Subject to satisfaction of any tax withholding obligation described in Section 5 below, Shares that are no longer subject to forfeiture will be transferred and delivered to the Executive as soon as administratively practicable after the date on which they vest in accordance with Section 2.1.

The Shares will be evidenced by one or more stock certificates (which shall remain in the custody of the Company) or will be credited to an electronic book-entry account maintained by the Company on behalf of Executive, and such certificate(s) or book entry (as applicable) will appropriately record the terms, conditions, and restrictions applicable to such Shares.

8

portion of the Shares that are forfeited or otherwise do not become vested in accordance with the Plan and this Agreement.

b.Exercise of Stockholder Rights.

c.Dividends and Distributions. Executive will be entitled to receive and retain all regular cash dividends and such other distributions, as the Board may, in its discretion, designate, pay or distribute on such Shares, if and when any such dividends or distributions are payable on Common Shares to shareholders of record after the Grant Date (unless and until the Shares are forfeited). Notwithstanding the foregoing, any such dividends or distributions declared shall be accumulated and paid at the time (and to the extent) that the Shares vest (or forfeited at the time that the Shares are forfeited), but in no event later than two-and-a-half months following the end of the calendar year in which the vesting occurs.

d.Legends. Certificates, if any, representing the Shares will contain the following or other legends in the Company's discretion:

THE SHARES REPRESENTED BY THIS CERTIFICATE ARE SUBJECT TO CERTAIN RESTRICTIONS UPON AND OBLIGATIONS WITH RESPECT TO TRANSFER AND RIGHTS OF REPURCHASE AS SET FORTH IN AN AGREEMENT BETWEEN THE COMPANY AND THE ORIGINAL REGISTERED HOLDER, A COPY OF WHICH IS ON FILE AT THE PRINCIPAL OFFICE OF THE COMPANY.

SECTION 6.MISCELLANEOUS.

b.Effect on Employee Benefits. Executive agrees that the Shares will constitute special incentive compensation that will not be taken into account as 'salary' or 'compensation' or 'bonus' in determining the amount of any payment under any pension, retirement, profit sharing or other remuneration plan of the Company unless so provided in such plan.

c.Further Assurances. The parties agree to execute such further instruments and to take such further action as may reasonably be necessary to carry out the intent of this Agreement.

d.Entire Agreement. This Agreement, including any exhibits, and the Plan together constitute the entire agreement of the parties with respect to the subject matter hereof and supersedes all prior oral and written understandings of the parties. This Agreement may be amended only as provided in the Plan.

e.No Guarantee of Future Awards. This Agreement does not guarantee Executive the right to or expectation of future Awards under the Plan or any future plan adopted by the Company.

f.Governing Law. This Agreement shall be governed by and construed in accordance with the laws of the State of Delaware without regard to conflicts of laws principles.

g.Counterparts. This Agreement may be signed in two counterparts, each of which will be an original, but both of which will constitute one and the same instrument.

h.Incentive Compensation Recoupment. Notwithstanding anything in the Plan or in this Agreement to the contrary, the Shares shall be subject to any compensation recovery and/or recoupment policy adopted by the Company to comply with applicable law, including, without limitation, the Dodd-Frank Wall Street Reform and Consumer Protection Act, or to comport with good corporate governance practices, as such policies may be adopted and/or amended from time to time.
