4 Exhibit 10.3 provided, however, that Company must terminate for Cause within 180 days of when the Board first knew or had reason to know of any of the foregoing circumstances or Company shall be deemed to have waived its right to terminate for Cause with respect to any such facts or circumstances; provided, further, that prior to termination, Executive must be given written notice and a cure period of thirty (30) days for any curable acts or omissions, and that no act, or failure to act, on Executive’s part will be considered Cause if done, or omitted to be done, based on the advice of the Company’s legal counsel or at the direction of the Board.

Compensation in the Event of Termination. (a) Cause or Resignation. If Executive’s employment terminates under Paragraph 7(d) or (e), Executive shall receive (i) payment of any earned but unpaid Base Salary earned up to and including the date of termination, and (ii) reimbursement of any unreimbursed business expenses (together, the “Accrued Obligations”).

5 Exhibit 10.3 (b) Death or Disability. If Executive’s employment terminates under Paragraph 7(a) or (b), Executive, or Executive’s estate, if applicable, shall receive the Accrued Obligations and any vested benefits Executive, or Executive’s estate, may be entitled to receive under any Company disability or insurance plan or other applicable employee benefit plan. Executive or Executive’s estate will not be required to repay any relocation reimbursements or other upfront compensation. Executive or Executive’s estate, as the case may be, also shall be entitled to receive the following, provided that (i) Executive or Executive’s estate, if applicable, has timely executed (and not revoked) a general release and waiver of all claims in a form acceptable to the Company and substantially similar to Exhibit B hereto (“General Release”) and (ii) any period of revocation applicable to such General Release has passed: (i) A single lump sum payment equal to ninety (90) days of Executive’s Base Salary as in effect on the date of Executive’s death or Disability; (ii) Any incentive compensation earned, in accordance with the applicable terms and conditions of the Incentive Plan, in the calendar year prior to termination of employment that has not been paid to Executive; and (iii) With respect to any Incentive Plan with annual objectives, a single lump sum cash payment in an amount equal to a prorated portion (calculated in the same manner as other senior executives and based on the number of calendar days that have elapsed during the year) of the payment to which Executive would be entitled under the Incentive Plan (had Executive’s death or Disability not occurred) for the calendar year in which Executive died or became Disabled. The payment to which Executive or Executive’s estate is entitled pursuant to paragraph (i) will be paid within thirty (30) days of Executive’s death or the effective date of Executive’s Disability, as the case may be. The payments to which Executive is entitled pursuant to paragraph (ii) shall be made within the time period described in the applicable Incentive Plan. In no event will the payments due pursuant to paragraphs (i) or (ii) be made later than March 15 of the year following the year in which Executive dies or the effective date of Executive’s Disability occurs. (c) Without Cause or by Executive for Good Reason. If Executive’s employment terminates prior to the expiration of the Term under Paragraph 7(c) or (f), Executive shall receive the Accrued Obligations and will not be required to repay any relocation reimbursements or other upfront compensation. Executive also shall be entitled to receive the following: (i) severance pay in an amount equal to 200% of Executive’s Base Salary in effect on the date Executive’s employment is terminated (the “Severance Payment”); if, however, the reason triggering a resignation for Good Reason is a reduction in Executive’s Base Salary, the severance pay will be calculated without regard to any such reduction; and (ii) Any incentive compensation earned, in accordance with the applicable terms and conditions of the Incentive Plan, in the calendar year prior to termination of employment that has not been paid to Executive; and

6 Exhibit 10.3 (iii) if Executive's employment is terminated in 2026, 200% of Executive's annual target compensation under Executive's Incentive Plan for 2026; or, if Executive's employment is terminated in 2027 or later, the greater of: (1) 200% of the annual compensation paid to Executive in the preceding year under the Incentive Plan in which Executive participates as of the date Executive’s employment is terminated, or (2) 200% of Executive’s Base Salary; (iv) a prorated portion (calculated in the same manner as other senior executives and based on the number of calendar days that have elapsed during the year) of the payment to which Executive would be entitled under the Incentive Plan (had Executive’s employment not been terminated) for the calendar year in which Executive’s employment is terminated; and (v) continued life, disability, accident and group health and dental insurance benefits, at substantially the levels Executive was receiving immediately prior to Executive’s termination of employment, for a period of time expiring upon the earlier of: (1) the end of the period of eighteen (18) months following Executive’s Separation from Service, or (2) the day on which Executive becomes eligible to receive any substantially similar benefits under any plan or program of any other employer or source without being required to pay any premium with respect thereto. Company will satisfy the obligation to provide the health and dental insurance benefits pursuant to this Section 8(c)(iii) by either paying for or reimbursing Executive for the actual cost of COBRA coverage (and Executive shall cooperate with Company in all respects in securing and maintaining such benefits, including exercising all appropriate COBRA elections and complying with all terms and conditions of such coverage in a manner to minimize the cost). Similarly, Company will reimburse Executive for the cost of comparable coverage for all other insurance benefits that are not subject to the COBRA continuation rules. It will be Executive’s responsibility to procure such benefits and Company will promptly reimburse Executive for the premiums for such benefits in the specified amount upon Executive’s submission of an invoice or other acceptable proof of payment. Company’s obligation under this paragraph will cease with respect to a particular type of coverage when and if Executive becomes eligible to receive substantially similar coverage with a successor employer. Subject to Section 15 herein, the Severance Payment will be paid in equal installments over a period of twenty-four (24) months in accordance with the Company’s regular paydays and commencing on the Company’s first regular payday that falls at least sixty (60) days following Executive’s termination of employment; provided that (i) Executive has timely executed (and not revoked) a General Release and (ii) any period of revocation applicable to such General Release has passed; provided, further, that the General Release shall be made available to Executive no later than five (5) days following the date of Executive’s termination of employment under Sections 7(c) or (f) herein. As shall be further described in the General Release, Executive shall have either twenty-one (21) or forty-five (45) days following receipt of the General Release to consider its execution and seven (7) days following the execution of the General Release to revoke it. If Executive fails to execute the General Release in a timely manner, or revokes the General Release, the benefits provided pursuant to this Section 8(c) (other than the Accrued Obligations) will not be due.

7 Exhibit 10.3 9. Change in Control of Company. (a) Eligibility to Receive Benefits. If a Change in Control (as defined in Section 9(c)) occurs, Executive shall be entitled to the benefits provided in Section 9(b) if, prior to the expiration of twenty-four (24) months after the Change in Control (i) Executive terminates employment with the Company for Good Reason in accordance with the requirements of Section 7(f) or (ii) the Company terminates Executive’s employment without Cause pursuant to Section 7(c). (b) Receipt of Benefits. If Executive is entitled to receive benefits pursuant to Section 9(a) hereof, Executive shall receive, in addition to the Accrued Obligation: (i) severance pay in an amount equal to: (a) 250% of the Executive's highest annualized Base Salary in effect on any date during the Initial Term or any Renewal Term; and (ii) if Executive's employment is terminated in 2026, 250% of Executive's annual target compensation under Executive's Incentive Plan for 2026; or, if Executive's employment is terminated in 2027 or later, the greater of: (1) 250% of the annual compensation paid to Executive in the preceding year under the Incentive Plan in which Executive participates as of the date Executive's employment is terminated or (2) 250% of Executive's Base Salary; and (iii) any incentive compensation earned, in accordance with the applicable terms and conditions of the Incentive Plan, in the calendar year prior to termination of employment that has not been paid to Executive and a prorated portion (based on the number of calendar days that have elapsed during the year) of the payment to which Executive would be entitled under the Incentive Plan (had Executive's employment not been terminated) for the calendar year in which Executive's employment is terminated; (iv) Executive shall be entitled to continue to receive life, disability, accident and group health and dental insurance benefits, at substantially the levels Executive was receiving immediately prior to Executive’s termination of employment, for a period of time expiring upon the earlier of: (1) the end of the period of eighteen (18) months following Executive’s Separation from Service, or (2) the day on which Executive becomes eligible to receive any substantially similar benefits under any plan or program of any other employer or source without being required to pay any premium with respect thereto. Company may satisfy the obligation to provide the health and dental insurance benefits pursuant to this Section 9(b)(ii) by either paying for or reimbursing Executive for the actual cost of COBRA coverage (and Executive shall cooperate with Company in all respects in securing and maintaining such benefits, including exercising all appropriate COBRA elections and complying with all terms and conditions of such coverage in a manner to minimize the cost). Similarly, Company will reimburse Executive for the cost of comparable coverage for all other insurance benefits that are not subject to the COBRA continuation rules. It will be Executive’s responsibility to procure such benefits and Company will promptly reimburse Executive for the premiums for such benefits in the specified amount upon Executive’s submission of an invoice or other acceptable proof of payment. Company’s

8 Exhibit 10.3 obligation under this paragraph will cease with respect to a particular type of coverage when and if Executive becomes eligible to receive substantially similar coverage with a successor employer; (v) Executive shall be vested, in accordance with the Equity Plan, in any and all equity-based plans and agreements of Company in which Executive had an interest, vested or contingent. If applicable law prohibits such vesting, then Company shall pay to Executive in a single lump sum cash payment in an amount equal to the value of benefits and rights that would have, but for such prohibition, been vested in Executive; and (vi) Subject to Section 15 herein, the benefits provided pursuant to this Section 9(b) (other than the Accrued Obligations) will be paid in a single lump sum on the Company’s first regular payday that falls at least sixty (60) days following Executive’s termination of employment; provided that (1) Executive has timely executed (and not revoked) a General Release and (2) any period of revocation applicable to such General Release has passed; provided, further, that the General Release shall be made available to Executive no later than five (5) days following the date of Executive’s termination of employment under Sections 7(c) or (f) herein. As shall be further described in the General Release, Executive shall have either twenty-one (21) or forty-five (45) days following receipt of the General Release to consider its execution and seven (7) days following the execution of the General Release to revoke it. If Executive fails to execute the General Release in a timely manner, or revokes the General Release, the benefits provided by this Section 9(b) (other than the Accrued Obligations) will not be due. The Incentive Plan payments to which Executive is entitled for the year or quarter of the Executive’s termination shall be made within the time period described in the applicable Incentive Plan, provided Executive has timely executed and not revoked a General Release as described above. In no event will the Incentive Plan payments be made later than March 15 of the year following the year in which Executive’s employment is terminated. (c) Change in Control Defined. For purposes of this Agreement, “Change in Control” shall have the meaning set forth in the Equity Plan. (d) Cap on Payments. (i) General Rules. The Internal Revenue Code (the “Code”) imposes significant tax consequences on Executive and Company if the total payments made to Executive due, or deemed due, to a “change in control” (as such term is defined in Section 280G(b)(2)(A)(i) of the Code and the regulations adopted thereunder) exceed prescribed limits. For example, if Executive’s “Base Period Income” is $100,000 and Executive’s “Total Payments” exceed 299% of such Base Period Income (the “Cap”), Executive will be subject to an excise tax under Section 4999 of the Code of 20% of all amounts paid to Executive in excess of $100,000. In other words, if Executive’s Cap is $299,999, Executive will not be subject to an excise tax if Executive receives exactly $299,999. If Executive receives $300,000, Executive will be subject to an excise tax of $40,000 (20% of $200,000). (ii) Reduction of Payments. Subject to the exception described in Section 9(d)(iii), in order to avoid the excise tax imposed by Section 4999 of the Code, one or more of the payments or benefits to which Executive is entitled that is not subject to Section

9 Exhibit 10.3 409A of the Code shall be reduced until the Total Payments equal the Cap. For purposes of this limitation: (1) No portion of the Total Payments shall be taken into account which, in the opinion of the Consultant retained pursuant to Section 9(d)(iv), does not constitute a “parachute payment” within the meaning of Section 280G(b)(2) of the Code; (2) A payment shall be reduced only to the extent necessary so that the Total Payments constitute reasonable compensation for services actually rendered within the meaning of Section 280G(b)(4) of the Code or are otherwise not subject to disallowance as deductions, in the opinion of the Consultant; and (3) The value of any non-cash benefit or any deferred payment of benefit included in the Total Payments shall be determined in accordance with Section 280G of the Code and the regulations issued thereunder. (4) If after the reductions called for by the preceding provisions of this Section 9(d)(ii), the Total Payments continue to exceed the Cap, the payments or benefits to which, Executive is entitled and which are subject to Section 409A shall be reduced proportionally until the Total Payments equal the Cap. (iii) Exception. The payment limitation called for by Section 9(d)(ii) shall not apply if Executive determines that he would prefer to receive the “Uncapped Benefit” rather than reduce the Total Payments in the manner outlined in Section 9(d)(ii). In the event Executive elects to receive the Uncapped Benefit, Executive will be solely responsible for any excise tax imposed by Section 4999 of the Code. The Consultant selected pursuant to Section 9(d)(iv) will calculate Executive’s Uncapped Benefit and Executive’ s Capped Benefit. For this purpose, the “Uncapped Benefit” is equal to the Total Payments to which Executive is entitled prior to the application of Section 9(d)(ii). Executive’s “Capped Benefit” is the amount to which Executive will be entitled after application of the limitations of Section 9(d)(ii). (iv) Consultant. Company will retain a “Consultant” to advise Company with respect to the applicability of any Section 4999 excise tax with respect to Executive’s Total Payments. The Consultant shall be a law firm, a certified public accounting firm, and/or a firm nationally recognized as providing executive compensation consulting services. All determinations concerning Executive’s Capped Benefit and Executive’s Uncapped Benefit (as well as any assumptions to be used in making such determinations) shall be made by the Consultant selected pursuant to this Section 9(d)(iv). The Consultant shall provide Executive and Company with a written explanation of its conclusions. All fees and expenses of the Consultant shall be borne by Company. The Consultant’s determination shall be bindi ng on Executive and Company. (v) Special Definitions. For purposes of this Section 9 (d), the following specialized terms will have the following meanings: (1) “Base Period Income.” “Base Period Income” is an amount equal to Executive’ s “annualized includable compensation” for the “base period’’ as defined in Sections 280G(d)(l) and (2) of the Code and the regulations adopted thereunder.

10 Exhibit 10.3 Generally, Executive ‘s “annualized includable compensation” is the average of Executive’s annual taxable income from Company for the “base period,” which is the five (5) calendar years prior to the year in which the change in control occurs. (2) “Cap” or “280G Cap.” “Cap” or “280G Cap” shall mean an amount equal to 2.99 times Executive’ s Base Period Income. This is the maximum amount which Executive may receive without becoming subject to the excise tax imposed by Section 4999 of the Code or which Company may pay without loss of deduction under Section 280G of the Code. (3) “Total Payments.” The “Total Payments” include any “payments in the nature of compensation” (as defined in Section 280G of the Code and the regulations adopted thereunder), made pursuant to this Agreement or otherwise, to or for Executive’s benefit, the receipt of which is contingent or deemed contingent on a change in control and to which Section 280G of the Code applies. (vi) Effect of Repeal. In the event that the provisions of Sections 280G and 4999 of the Code are repealed without succession, Section 9(d) shall be of no further force or effect. (vii) Employment by Successor. For purposes of this Agreement, employment by a successor of Company or a successor of any subsidiary of Company that has assumed this Agreement shall be considered to be employment by Company or one of its subsidiaries. As a result, if Executive is employed by such a successor following a Change in Control, Executive will not be entitled to receive the benefits provided by Section 9 unless Executive’s employment with the successor is subsequently terminated without Cause or for Good Reason within twenty-four (24) months following the Change in Control. 10. Confidentiality, Intellectual Property, Non-Solicitation, and Non-Competition Agreement. As a condition of employment, Executive also must sign the Confidentiality, Intellectual Property, Non-Solicitation and Non-Competition Agreement, which is attached as Exhibit A to this Agreement. 11. Applicable Law. This Agreement and any disputes or claims arising hereunder shall be construed in accordance with, governed by and enforced under the laws of the State of Arizona without regard for any rules of conflicts of law. 12. Company Policies. (a) General Company Policies. Except where inconsistent with the terms of this Agreement, Executive agrees that he will be subject to, and comply with, the employment policies and procedures established by the Company from time to time. (b) Company Stock Ownership Guidelines. Executive agrees that he will be subject to the Company’s stock ownership guidelines.

11 Exhibit 10.3 (c) Clawback. To the extent required by law or Company policy, the Company may require Executive to repay to the Company any bonus or other incentive-based or equity- based compensation paid to Executive. 13. Section 16 of the Securities Exchange Act. If, at the time Executive’s employment is terminated for any reason, Executive is a person designated to file pursuant to Section 16 of the Securities Exchange Act of 1934 (the “1934 Act”), Executive will provide to the Company a written representation in a form acceptable to the Company that all reportable pre- termination securities transactions relating to Executive have been reported. 14. Withholding. The Company may effect withholdings from the payments due to Executive under this Agreement for the payment of taxes and other lawful withholdings or required employee contributions, in accordance with applicable law. 15. Section 409A. (a) It is the intention of the Company and Executive that this Agreement not result in unfavorable tax consequences to Executive under Section 409A of the Code (“Section 409A”). To the extent applicable, it is intended that the Agreement comply with the provisions of Section 409A, but the Company does not warrant or guarantee that the Agreement is either excepted from the requirements of Section 409A or that the Agreement complies with Section 409A. The Agreement will be administered and interpreted in a manner consistent with this intent, and any provision that would cause the Agreement to fail to satisfy Section 409A will have no force and effect until amended to comply therewith (which amendment may be retroactive to the extent permitted by Section 409A). The Company and Executive agree to work together in good faith in an effort to comply with Section 409A including, if necessary, amending this Agreement based on further guidance issued by the Internal Revenue Service from time to time, provided that the Company shall not be required to assume any increased economic burden. Executive remains solely responsible for any adverse tax consequences imposed upon him by Section 409A. (b) Notwithstanding anything contained herein to the contrary, to the extent required in order to avoid accelerated taxation and/or tax penalties under Section 409A, Executive shall not be considered to have terminated employment with the Company for purposes of the Agreement and no payments shall be due to him under the Agreement which are payable upon his termination of employment until he would be considered to have incurred a “separation from service” from the Company within the meaning of Section 409A. (c) To the extent required in order to avoid accelerated taxation and/or tax penalties under Section 409A, amounts that would otherwise be payable and benefits that would otherwise be provided upon Executive’s termination of employment pursuant to the Agreement during the six-month period immediately following Executive’s termination of employment shall instead be paid within thirty (30) days following the first business day after the date that is six months following his termination of employment (or upon his death, if earlier). If it is determined that all or a portion of the payments due pursuant to this Agreement are subject to Section 409A of the Code, and if the General Release consideration period and revocation period spans two calendar years, the payments provided pursuant to this Agreement that are subject to Section 409A shall not begin until the second calendar year. Executive may not elect the taxable year of the

12 Exhibit 10.3 distribution. In addition, for purposes of this Agreement, each amount to be paid or benefit to be provided to the Executive pursuant to this Agreement shall be construed as a separate identified payment for purposes of Section 409A. (d) 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 the Company 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. 16. Dispute Resolution. The Parties agree that any controversy, dispute or claim arising out of or relating to the Agreement or breach thereof, including without limitation Executive’s employment with or separation of employment from Company, and all claims, to the extent allowable by law, that Company or any of its representatives engaged in conduct prohibited on any basis under any federal, state, or local statute, including federal or state discrimination statutes or public policy, shall be resolved by final, binding and conclusive arbitration in Maricopa County, Arizona, with a sole arbitrator to be mutually agreed upon by the Parties. The Company shall bear the cost of the arbitrator. The arbitration shall occur within thirty (30) days of selection of the arbitrator and shall be administered by the American Arbitration Association under its Employment Arbitration Rules and judgment upon the award rendered by the arbitrator may be entered in any court having jurisdiction thereof. Any arbitration award may, in the discretion of the arbitrator, include reasonable attorneys’ fees and costs of the prevailing party. “Attorneys’ fees and costs” mean all reasonable pre-award expenses, administrative fees, travel expenses, out- of-pocket expenses such as copying and telephone costs, witness fees and attorneys’ fees. Any award of attorney’s fees and costs to which Executive may be entitled shall be paid by Company, on or before December 31 of the calendar year following the year of the conclusion of the arbitration. Either party may apply to the arbitrator to seek injunctive relief until the arbitration award is rendered or the matter is otherwise resolved. Either party also may, without waiving any remedy under the Agreement, seek from any court having jurisdiction any interim or provisional relief, including a temporary restraining order, an injunction both preliminary and final, and any other appropriate equitable relief, that is necessary to protect the rights or property of that party, pending the retention of the arbitrator. 17. No Conflict.

Shortening of Statue of Limitations. To the extent any law allows Employee to bring a legal claim against Insight, Employee agrees to bring any claim within the time provided by law or no later than six (6) months from the date of the event forming the basis of the claim, whichever expires first. To the fullest extent permitted by law, Employee recognizes and acknowledges that Employee is agreeing to bring any claim Employee may have within a shorter time than may otherwise be provided by law. 9. Third-Party Beneficiary. Employee and Insight agree that each Insight subsidiary and corporate affiliate is expressly intended to be a third-party beneficiary of this Agreement with full rights to enforce the obligations, rights, undertakings, and commitments under this Agreement and its Attachments. 10. Entire Agreement. This Agreement, including its Attachments, is the entire agreement of the Parties on these subject matters. Except as may exist in any Insight equity plan or compensation plan to which Employee is a participant, there are no other promises or conditions concerning this subject matter in any other agreement whether oral or written, and this Agreement supersedes any prior written or oral agreements between the Parties concerning these subject matters. 11. Amendment. This Agreement may only be amended by a writing signed by both Parties. 12. Severability. If any provision of this Agreement or its Attachments is held by a court of competent jurisdiction or arbitrator to be invalid or unenforceable, the remaining provisions of the Agreement and the Attachments shall continue to be valid and enforceable. If a court of competent

Exhibit 10.3 jurisdiction or arbitrator finds that any provision of this Agreement or its Attachments is invalid or unenforceable, but that by limiting, editing, or revising such language, it would become valid or enforceable, then such provision shall be deemed to be written, construed, and enforced as so limited, edited, or revised. 13. Attorneys’ Fees. In any action seeking, in whole or in part, enforcement of the Agreement, challenging the enforceability of any provision of this Agreement, or for a breach or threatened breach of this Agreement, the prevailing Party will be entitled to recover its attorneys’ fees and costs. 14. Waiver of Rights. If, on one or more occasions, either Party fails to insist that the other Party perform any of the terms of this Agreement, such failure shall not be construed as a waiver by such Party of any past, present, or future right granted under this Agreement, and the obligations of the Parties shall continue in full force and effect. Further, Insight’s failure to seek to enforce a similar agreement with any other Insight employee shall not constitute a waiver of Insight’s rights under this Agreements. 15. Governing Law. Section 3 of this Agreement shall be governed by and interpreted pursuant to the Federal Arbitration Act. Otherwise, the governing law for this Agreement and its Attachments shall be: i) the state in which Employee works if Employee works for Insight in Arizona, California, Florida, Illinois, Ohio, Texas, or Washington, without regard to such state’s conflicts of law principles; or ii) Delaware, without regard to its conflicts of law principles, if Employee works in any state other than those listed in the preceding clause. The Parties agree that, in the event of a dispute, Insight’s records indicating the state of employment for Employee shall be used to determine the governing law. 16. Enforcement of Restrictive Covenants. Employee understands and agrees that the breach by Employee of the restrictive covenants contained in Section 4, 6, or 7 of this Agreement, as more fully defined in Attachments A, B, and C, could not reasonably or adequately be fully compensated in damages in an action at law. Therefore, Insight shall be entitled, without the necessity of showing any actual damages or that money damages would not afford an adequate remedy, and without the necessity of posting bond, to injunctive relief. The injunctive relief may include, but is not limited to, restraining Employee from rendering any service or making any disclosure that would breach any restrictive covenant in this Agreement. If Insight is successful in obtaining such injunctive relief, the duration of the restrictive covenant shall be tolled and computed from the date such relief is granted, reduced by the time period between termination of Employee’s employment and the date of the first breach by Employee. No remedy conferred by this Agreement (including this Section) is intended to be exclusive of any other remedy. Each and every remedy shall be cumulative and shall be in addition to every other remedy given hereunder, or now or hereafter existing in law or in equity, by statute or otherwise. The election of any one or more remedies by Insight shall not constitute a waiver of the right to pursue other available remedies. To the extent that any of the restrictive covenants contained in this Agreement conflict with any of Employee’s obligations in Insight’s compensation or equity plan agreements or plans, or contained in any separate agreements that Employee signed with Insight regarding the treatment

Exhibit 10.3 of confidential or proprietary information or containing any restrictive covenants, including, but not limited to, not to compete or not to solicit clients, customers, or employees, Employee acknowledges and agrees that Insight may seek to enforce all such covenants. But in the event of an irreconcilable conflict, Insight may choose, in its sole discretion, which covenant(s) it seeks to enforce. If any of the restrictive covenants contained in Section 4, 6, or 7 of this Agreement are deemed by a court of competent jurisdiction or arbitrator to be unenforceable under applicable law and incapable of being limited, edited, or revised to become valid and enforceable, then the restrictive covenants previously agreed to by Employee and Insight shall remain enforceable. 17. Successors and Assigns – Binding Effect. This Agreement shall not be assignable by Employee. The rights and obligations of the Parties under this Agreement shall be binding upon and shall inure to the benefit of Insight and Insight’s successors and assigns. This Agreement may be enforced by Insight’s assignee or successor. 18. Survival. Employee understands and agrees that the obligations, commitments, undertakings, and covenants set forth in this Agreement, including but not limited to those set forth in Sections 3, 4, 5, 6, 7 and 8 shall survive the termination of Employee’s employment with Insight. 19. Voluntary Agreement; Legal Review; Counterparts. Employee agrees that Employee: i) has read and understands this Agreement and its Attachments in their entirety; ii) may before signing this Agreement, if Employee desires, obtain advice from legal counsel of Employee’s choice to advise Employee on this Agreement; iii) has freely and voluntarily entered into this Agreement; and iv) understands this Agreement may be signed separately by each Party, electronically or physically, and may be transmitted via PDF, facsimile, or otherwise, and each signature page when combined with a copy of the preceding pages of this Agreement shall constitute the full agreement.

The parties wish to settle and compromise fully and finally any and all claims arising between them including, but not limited to, those arising out of Employee’s employment and the termination of that employment, on the terms and conditions set forth in this Agreement. C. Employee represents that Employee is forty (40) years of age or older. AGREEMENTS In consideration of the mutual promises in this Agreement, it is agreed as follows: 1. Recitals. The parties hereby acknowledge the correctness and accuracy of the foregoing recitals. 2. Payment and Other Benefits. (a) Upon receipt of this signed Agreement and beginning within twenty-one (21) days after the expiration of the revocation period referenced in Section 7 of this Agreement, the Company will provide severance pay in an amount equal to percent of Employee’s base salary (which Employee acknowledges to be $ ) and percent of the annual compensation paid to Employee in the preceding year under the Incentive Plan in which Employee participated as of the Employee’s termination date, payable in installments over a period of twenty- four (24) months in accordance with the Company’s normal payroll periods and practices beginning with the first payroll period following the Effective Date of this Agreement (the “Payments”). The Payments shall be made by direct deposit based on the account information that the Employee has on file with the Company. If Employee has not elected for direct deposit, Company will provide Employee an ADP ALINE card for the Payments. (b) As additional consideration, upon receipt of this signed Agreement and following the expiration of the revocation period referenced in Section 7 of this Agreement, the Company will also begin to provide to Employee continued life, disability, accident and group health and dental insurance benefits, at substantially the levels Employee was receiving immediately prior to termination. Company will satisfy the obligation to provide the health and dental insurance benefits pursuant to this Section 8(c)(iii) by either paying for or reimbursing

Exhibit 10.3 Employee for the actual cost of COBRA coverage (and Employee shall cooperate with Company in all respects in securing and maintaining such benefits, including exercising all appropriate COBRA elections and complying with all terms and conditions of such coverage in a manner to minimize the cost). Similarly, Company will reimburse Employee for the cost of comparable coverage for all other insurance benefits that are not subject to the COBRA continuation rules. It will be Employee’s responsibility to procure such benefits and Company will promptly reimburse Employee for the premiums for such benefits in the specified amount upon Employee’s submission of an invoice or other acceptable proof of payment. Company’s obligation under this paragraph will cease with respect to a particular type of coverage when and if Employee becomes eligible to receive substantially similar coverage with a successor employer 3. Acknowledgement of Consideration. Employee understands and agrees that Employee is receiving the Payments and benefits described in Section 2 in exchange for Employee’s promises in this Agreement and that Employee is not otherwise entitled to those items. The Company will pay Employee wages through Employee’s last day of employment without regard to whether Employee executes this Agreement. 4. Release, Representations and Acknowledgments. (a) In exchange for the severance pay, Employee, for himself/herself and, as applicable, Employee’s spouse, marital community, agents, heirs, executors, and assigns, hereby fully, forever, irrevocably, and unconditionally releases and discharges the Company, its parent, subsidiary, and affiliated companies, and the officers, directors, shareholders, agents, predecessors, successors, assigns, and current and past employees of each and all of the foregoing (“Released Parties”) from any and all claims, complaints, liabilities, damages, and obligations of any nature whatsoever, which Employee has, had, or may have against Released Parties, whether now known or unknown, and whether asserted or unasserted, arising out of or from any act, event, or omission occurring before the effective date of this Agreement. Without limiting the foregoing, this release includes any and all claims arising out of or which could arise out of the employment relationship between Employee and the Company and the termination of that employment, including, but not limited, to any and all claims under the following laws, as amended: Title VII of the Civil Rights Act of 1964; the Americans with Disabilities Act; Section 1981 of the Civil Rights Act of 1866; the Age Discrimination in Employment Act; the Equal Pay Act; the Family Medical Leave Act; the Fair Labor Standards Act; the Employee Retirement Income Security Act (ERISA); the National Labor Relations Act; the Fair Credit Reporting Act; the Labor Management Relations Act; the Genetic Information Non-Discrimination Act; Consolidated Omnibus Budget Reconsolidation Act (COBRA); the Worker Adjustment and Retraining Notification Act; the False Claims Act; Uniformed Services Employment and Reemployment Rights Act; the Lilly Ledbetter Fair Pay Act of 2009; the Arizona Civil Rights Act; the Arizona Employment Protection Act; the anti-retaliation provisions of the Arizona Workers’ Compensation Act; any Arizona laws governing wages and hours (A.R.S. Title 23); all federal, state, and local civil rights, employment, whistleblower, or wage payment laws, statutes, regulations, ordinances, or orders; and any other provision or theory of law arising out of any federal or state constitution, statute, regulation, ordinance, civil code, administrative code, or common law, either in tort, contract, or restitution. This release may be pled as a complete bar and defense to any claim brought by Employee with respect to the matters released in this Agreement. This release does not waive claims that may arise after the date this Agreement is signed, any vested rights under any Company sponsored or

Exhibit 10.3 administered group employee welfare benefit or 401(k) plan, or any claims that cannot be released as a matter of law. (b) Employee acknowledges and agrees that the severance pay Employee is receiving under this Agreement is sufficient consideration to support the release of all entities identified in this Section 4, and this consideration is in addition to anything of value to which Employee is already entitled. (c) Employee represents and warrants that there are no administrative charges with government agencies known to Employee pending against the Company or one of its parent, subsidiary, or affiliated companies. Employee agrees that Employee has not filed, or caused to be filed, any claim or charge with any adjudicative body, regulatory body, or agency arising out of Employee’s employment or the termination of that employment. (d) Employee acknowledges and agrees that Employee is waiving Employee’s right to file a lawsuit under the Age Discrimination in Employment Act, as amended by the Older Workers Benefit Protection Act. (e) Employee acknowledges and agrees that Employee has been granted any FMLA leave to which Employee was entitled and has not been subjected to any discrimination or retaliation for using FMLA leave. (f) Employee acknowledges and agrees that Employee has received all monies, meal and rest breaks, and leave allotments owed Employee for Employee’s employment and has not been subjected to any discrimination or retaliation for raising any issues regarding compensation or benefits issues. (g) Protected Rights. Employee understands that nothing contained in this Agreement limits Employee's ability to file a charge or complaint with the Equal Employment Opportunity Commission, the National Labor Relations Board, the Occupational Safety and Health Administration, the Securities and Exchange Commission or any other federal, state or local governmental agency or commission ("Government Agencies"). Employee further understands that this Agreement does not limit Employee's ability to communicate with any Government Agencies or otherwise participate in any investigation or proceeding that may be conducted by any Government Agency, including providing documents or other information, without notice to the Company. This Agreement does not limit Employee's right to receive an award for information provided to the Securities and Exchange Commission. 5. No Double Pay. If Employee accepts another position with the Company or one of its parent, subsidiary, or affiliated companies during the period for which Employee has received severance pay, Employee agrees to repay or forfeit severance pay for the period which overlaps with the new employment. For purposes of illustration only, if Employee receives severance pay of six weeks and is hired for a position with the Company after four weeks, the Employee would forfeit two weeks of severance pay. 6. Review. Employee has been advised in writing by this agreement that Employee has up to twenty-one (21) days from the date Employee is presented with this Agreement to consider and sign this Agreement. If Employee signs this Agreement before the expiration of

Exhibit 10.3 twenty-one (21) days, Employee acknowledges that Employee has done so for the purpose of expediting the resolution of this matter and that Employee has expressly waived Employee’s right to take twenty-one (21) days to consider this Agreement. To accept the offer in this Agreement, Employee must sign and return the Agreement to the Company within the 21-day period. If Employee has not signed this Agreement within the time frame set forth above, this Agreement shall be deemed rejected by Employee, and Employee will not be able to later accept it. 7. Revocation; Effective Date. Employee may revoke this Agreement for a period of seven (7) days after Employee signs it. Employee agrees that if Employee elects to revoke this Agreement, Employee will notify Brandy Richards at the Company by emailing Brandy.Richards@Insight.com on or before the expiration of the revocation period. Receipt by the Company of proper and timely notice of revocation from Employee cancels and voids this Agreement. Provided that Employee does not provide a timely written notice of revocation, this Agreement will become effective upon expiration of the revocation period. 8. Return of Company Property. Employee represents that Employee has made a diligent search and has already returned to the Company all documents including, but not limited to, all electronic information, papers, and all copies of such material and other property that Employee has had in Employee’s possession at any time, including, but not limited to, files, notes, drawings, records, business plans and forecasts, financial information, specifications, computer- recorded information, tangible property including, but not limited to, computers, disks, CDs, flash drives, hard drives, entry cards, identification badges and keys, and any materials of any kind that constitute property of the Company, its parent, subsidiary, or affiliated companies or that contains or embodies any proprietary or confidential information of the Company, its parent, subsidiary, or affiliated companies. Employee agrees to make a diligent search for all such property and to return any property not previously returned within five (5) days of execution of this Agreement. Employee further agrees to provide to the Company, within five (5) days of execution of this Agreement, with a computer-useable copy of any such proprietary data, materials, or information received, stored, reviewed, prepared, or transmitted on any personal computer, server, or e-mail system, to the extent the same may be retrieved from such computers, servers, and e-mail system, and, then, to delete such information from those personal computers, servers, and e-mail systems. 9. Confidentiality. Employee agrees that Employee will keep the terms and fact of this Agreement confidential. Employee will not disclose the terms of this Agreement to anyone except Employee’s spouse, attorneys, or accountants, unless required by law. 10. Other Confidentiality Obligations. As a supplement to Employee’s existing confidentiality obligations, Employee acknowledges and agrees that nothing in this agreement or other confidentiality agreements with the Company prevents Employee from disclosing confidential information that: (A) is made: (i) in confidence to a Federal, State, or local government official, either directly or indirectly, or to Employee’s attorney; and (ii) solely for the purpose of reporting or investigating a suspected violation of law; or (B) is made in a complaint or other document filed in a lawsuit or other proceeding by Employee or Employee’s attorney, if such filing is made under seal. In the event that Employee files a lawsuit alleging retaliation by the Company for reporting a suspected violation of law, Employee may disclose confidential information related to the suspected violation of law or alleged retaliation to Employee’s attorney and use that confidential information in the court proceeding if Employee or his/her attorney: (A) files any

Exhibit 10.3 document containing confidential information under seal; and (B) does not disclose the confidential information, except pursuant to court order. The Company provides this notice in compliance with the Defend Trade Secrets Act of 2016. 11. Non-Disparagement. Employee covenants and agrees that Employee will not disparage, defame, or communicate any false statements about the Released Parties in any manner whatsoever, including, but not limited to, by not posting defamatory comments on social networking, blogs, or Internet websites. 12. Fees and Costs. In the event of any litigation arising under this Agreement, the parties agree that the prevailing party shall be entitled to recover its reasonable attorneys’ fees and costs from the other party. 13. Severability. Should any provision in this Agreement be declared or determined to be illegal or invalid, the validity of the remaining parts, terms, or provisions shall not be affected and the illegal or invalid part, term, or provision shall be deemed not to be a part of this Agreement. 14. Acknowledgement of Opportunity to Review with Attorney.

Employee represents and agrees that Employee has read and fully understands all of the provisions of this Agreement, and that Employee is voluntarily entering into this Agreement with a full and complete understanding of all of its terms. 15. Integration.

NOTWITHSTANDING THE FOREGOING, Employee acknowledges and agrees that this Agreement does not limit, modify, amend, or supersede, in any way, Employee’s obligations to abide by any agreement Employee signed with the Company regarding arbitration or alternative dispute resolution, the treatment of confidential or proprietary information of the Company or one of its subsidiaries or affiliated companies or containing any restrictive covenants, including, but not limited to, any covenants not to solicit clients, customers, or employees, or not to compete. 16. Choice of Law. This Agreement shall be governed by and construed in accordance with the laws of the State of Arizona. 17. Amendment.

Successors and Assigns. This Agreement is and shall be binding upon and inure to the benefit of the heirs, executors, successors, and assigns of each of the parties. 19. Non-Admission.

Exhibit 10.3 March 4, 2026 Jacob (aka Jack) Azagury [***] Welcome to Insight, Jack! We are thrilled to extend to you an offer to lead Insight as our Chief Executive Officer. After careful consideration of your qualifications and experience (and countless interviews!), we are confident that your skills and capabilities align with our company’s vision and values, and our strategic goals.

Wages for this position are exempt and paid semi- monthly. VARIABLE INCENTIVE You’ll be eligible to participate in our Officer Incentive Plan. Your annual variable target will be 150% of base pay upon achievement of 100% of targets. For 2026, the metrics are: 1. Insight Enterprises Inc (IEI) Earnings from Operations – 50% 2. IEI Services Revenue – 25% 3. IEI Total GP – 25% Your variable incentive payment for 2026 will be prorated for the length of time you were in role. I will provide further details on metrics and grids, and will share with you how your plan aligns with the rest of the corporate officers. Please keep in mind that the Board of Directors reviews variable incentive metrics annually and may change the metrics and/or the attainment grids each year. RELOCATION BONUS Your role will be located in our beautiful Chandler, Arizona headquarters. To assist in your relocation to the area, we’re pleased to offer you a one-time relocation bonus of $1,000,000, intended to cover expenses incurred in your move, including but not limited to: any necessary Arizona temporary housing expenses, expenses related to the physical relocation of household goods, and any real estate agent commissions or closing costs on real estate transactions. The bonus will be paid out in two installments: (1) the first installment of $500,000 will be paid within the three months of your hire date, and (2) the second installment of $500,000 will be paid following confirmation of your relocation to the Phoenix valley (please keep me informed about your move). The two bonus installments will be taxable income. Except in the event of death, disability, or termination without Cause or for Good Reason, should you leave Insight prior to completing one year of service following payment of the second relocation installment, you will be required to reimburse Insight for the full amount paid to you under this section. INSIGHT EQUITY – RESTICTED STOCK UNITS Annual Equity Grants

Exhibit 10.3 Insight intends to award you a grant of restricted stock units (RSUs) on April 15th—subject to all necessary approvals having been obtained before the intended grant date. The value of the

Exhibit 10.3 proposed award will be USD $8,000,000. The award will consist of 40% service-based RSUs and 60% performance-based RSUs. The final number of service-based RSUs granted and performance-based RSUs at target attainment will be calculated based on the closing stock price of NSIT on the date of grant. The service-based RSUs will vest annually over three years from the date of grant and are subject to the terms and conditions of the 2020 Omnibus Plan, as amended. The performance-based RSUs will be allocated equally between the two performance metrics below. The first performance metric is Return on Invested Capital (“ROIC”). These performance-based RSUs are adjusted up or down based on Insight’s achievement of ROIC compared to a grid approved by the Compensation Committee in February 2026 with a range of 0 – 200% for the performance period of January 1, 2026 – December 31, 2026. The actual number of shares granted are subject to attainment upon completion of the performance period and the granted shares will vest in equal annual installments over three years beginning on February 20, 2027. The second performance metric is Relative Total Shareholder Return (“rTSR”). These performance-based RSUs are adjusted up or down based on Insight’s achievement of rTSR compared to a peer group and a performance grid determined by the Compensation Committee with a range of 0 – 200%. The performance period runs from January 1, 2026 through December 31, 2028. The number of shares granted are subject to attainment upon completion of the performance-period and will vest in full upon certification of the rTSR performance by the Compensation Committee in February 2029. All RSUs granted pursuant to this section are subject to the terms and conditions of the 2020 Omnibus Plan, as amended. One-Time Inducement Performance-Based Award Insight intends to award you a one-time inducement grant of performance-based RSUs on April 15th—=subject to all necessary approvals having been obtained before the intended grant date. The value of the proposed award will be USD $10,000,000. The performance metric for these shares is Absolute Total Shareholder Return (“aTSR”). The number of performance-based RSUs granted at target (100%) attainment will be calculated based on the closing stock price of NSIT on the date of grant. The performance period runs from April 15, 2026 through April 15, 2029. The number of shares granted are subject to attainment of three pre-established stock price tiers. Attaining the first price tier will earn 50% of the target RSUs. The second price tier will earn an additional 50% of the target RSUs. The third price tier will earn an additional 100% of the target RSUs. Once a tier is reached, the corresponding target percentage will be deemed earned as of the date that the stock price remains above the floor of the price tier for twenty (20) consecutive trading days. In all cases, any earned stock will vest on April 15, 2029. Other key features of the grant are as follows: • No Interpolation: Achievement is determined solely by the attainment of the specific Share Price Goals. Amounts between tiers do not earn any portion of the RSUs. • Closing Price Only: Achievement is measured exclusively by the Closing Prices over the required period. Intraday prices (e.g., intraday highs) are disregarded. • No Closing Price Rounding: The actual NSIT Closing Prices used to determine performance against the Tier levels will not be rounded to the nearest dollar. The Closing Prices must be at or above the applicable Share Price Goal to satisfy a tier. As explained below, the Share Price Goals are rounded to the nearest dollar.

Exhibit 10.3 Stock price tiers will be determined based on the NSIT closing price on April 15, 2026. To qualify for a tier during the performance cycle, the stock must meet both the growth percentage and the minimum price threshold as outlined below (rounded to the nearest dollar): • Tier 1: 118% growth (Minimum price: $100) • Tier 2: 160% growth (Minimum price: $135) • Tier 3: 200% growth (Minimum price of $135 still applies) The tiers with various examples are illustrated below: * Although the calculated value is $136, we have adjusted it to $135 to remain consistent with Jack’s original CEO Pay Proposal, provided by Meridian. If $135 is achieved, Tier 2 will be earned, even though it is slightly short of the growth requirement of 160%. Once earned, the RSUs remain subject to vesting (on April 15, 2029) and are subject to the terms and conditions of the 2020 Omnibus Plan, as amended. Subsequent share price declines do not reduce previously earned RSUs. OUR VALUES We expect all teammates to embody our core values in their daily work. I will follow up with a guide detailing the specific behaviors associated with each value. BENEFITS As a new teammate, you’re eligible for our many benefit plans. Please refer to the 2026 Benefit Enrollment Guide, which I will send to you electronically. You can enroll after you have started work and have access to Insight’s intranet.

Exhibit 10.3 If you enroll in a qualified medical plan and complete your wellness requirements, we’ll fund a Health Savings Account for you. That money is yours and can pay for qualified medical expenses. It’s a great account because it’s yours forever, it offers significant tax advantages and it can grow over time.

The 3% deduction starts approximately 30 days following your hire date, unless you opt out or choose a different contribution percentage.

(f) As provided in this Section 7(f), upon written notice by Executive to the Company stating that Executive is resigning from his employment with the Company for “Good Reason.” For purposes of this Agreement, “Good Reason” shall be defined as: (i) a material diminution in Executive’s authority, duties or responsibilities without his consent; (ii) a material reduction in Executive’s Base Salary, other than as part of a Company salary reduction program that includes senior executives of the Company; (iii) any material act or acts of dishonesty by the Company directed toward or affecting Executive; (iv) any illegal act or instruction directly affecting Executive by Company, which is not withdrawn after the Company is notified of the illegality by Executive; or

.6 4 (v) the Company’s material breach of this Agreement; provided, however, that Executive must resign within 180 days of the initial occurrence of any of the foregoing circumstances and must provide written notice to the Chief Executive Officer of the facts and circumstances Executive alleges constitute Good Reason within ninety (90) days of the first occurrence of such fact or circumstance or Executive shall be deemed to have waived Executive’s right to terminate for Good Reason with respect to any such facts or circumstances; provided, further, that none of the actions set forth in (i)-(v) above shall constitute Good Reason if the action is cured or otherwise remedied by the Company within thirty (30) business days after receiving written notice from the Executive. 8. Compensation in the Event of Termination. (a) Cause or Resignation. If Executive’s employment terminates under Paragraph 7(d) or (e), Executive shall receive (i) payment of any earned but unpaid Base Salary earned up to and including the date of termination, and (ii) reimbursement of any unreimbursed business expenses (together, the “Accrued Obligations”). (b) Death or Disability. If Executive’s employment terminates under Paragraph 7(a) or (b), Executive, or Executive’s estate, if applicable, shall receive the Accrued Obligations and any vested benefits Executive, or Executive’s estate, may be entitled to receive under any Company disability or insurance plan or other applicable employee benefit plan. Executive or Executive’s estate, as the case may be, also shall be entitled to receive the following, provided that (i) Executive or Executive’s estate, if applicable, has timely executed (and not revoked) a general release and waiver of all claims in a form acceptable to the Company and substantially similar to Exhibit B hereto (“General Release”) and (ii) any period of revocation applicable to such General Release has passed: (i) A single lump sum payment equal to ninety (90) days of Executive’s Base Salary as in effect on the date of Executive’s death or Disability; (ii) Any incentive compensation earned, in accordance with the applicable terms and conditions of the Incentive Plan, in the calendar year prior to termination of employment that has not been paid to Executive; and (iii) With respect to any Incentive Plan with annual objectives, a single lump sum cash payment in an amount equal to a prorated portion (based on the number of calendar days that have elapsed during the year) of the payment to which Executive would be entitled under the Incentive Plan (had Executive’s death or Disability not occurred) for the calendar year in which Executive died or became Disabled. The payment to which Executive or Executive’s estate is entitled pursuant to paragraph (i) will be paid within thirty (30) days of Executive’s death or the effective date of Executive’s Disability, as the case may be. The payments to which Executive is entitled pursuant to paragraphs (ii) and (iii) shall be made within the time period described in the applicable Incentive Plan. In no event will the payments due pursuant to paragraphs (i) or (ii) be made later than March 15 of the year following the year in which Executive dies or the effective date of Executive’s Disability occurs.

.6 5 (c) Without Cause or by Executive for Good Reason. If Executive’s employment terminates prior to the expiration of the Term under Paragraph 7(c) or (f), Executive shall receive the Accrued Obligations. Executive also shall be entitled to receive the following: (i) severance pay in an amount equal to 100% of Executive’s Base Salary in effect on the date Executive’s employment is terminated (the “Severance Payment”); if, however, the reason triggering a resignation for Good Reason is a reduction in Executive’s Base Salary, the severance pay will be calculated without regard to any such reduction; and (ii) any incentive compensation earned, in accordance with the applicable terms and conditions of the Incentive Plan, in the calendar year prior to termination of employment that has not been paid to Executive; and (iii) with respect to any Incentive Plan with annual objectives, a prorated portion (based on the number of calendar days that have elapsed during the year) of the payment to which Executive would be entitled under the Incentive Plan (had Executive’s employment not been terminated) for the calendar year in which Executive’s employment is terminated; and (iv) continued life, disability, accident and group health and dental insurance benefits, at substantially the levels Executive was receiving immediately prior to Executive’s termination of employment, for a period of time expiring upon the earlier of: (1) the end of the period of twelve (12) months following Executive’s Separation from Service, or (2) the day on which Executive becomes eligible to receive any substantially similar benefits under any plan or program of any other employer or source without being required to pay any premium with respect thereto. Company will satisfy the obligation to provide the health and dental insurance benefits pursuant to this Section 8(c)(iii) by either paying for or reimbursing Executive for the actual cost of COBRA coverage (and Executive shall cooperate with Company in all respects in securing and maintaining such benefits, including exercising all appropriate COBRA elections and complying with all terms and conditions of such coverage in a manner to minimize the cost). Similarly, Company will reimburse Executive for the cost of comparable coverage for all other insurance benefits that are not subject to the COBRA continuation rules. It will be Executive’s responsibility to procure such benefits, and Company will promptly reimburse Executive for the premiums for such benefits in the specified amount upon Executive’s submission of an invoice or other acceptable proof of payment. Company’s obligation under this paragraph will cease with respect to a particular type of coverage when and if Executive becomes eligible to receive substantially similar coverage with a successor employer. Subject to Section 15 herein, the Severance Payment will be paid in equal installments over a period of twelve (12) months in accordance with the Company’s regular paydays and commencing on the Company’s first regular payday that falls at least sixty (60) days following Executive’s termination of employment; provided that (i) Executive has timely executed (and not revoked) a general release and waiver of all claims in a form acceptable to the Company (“General Release”) and (ii) any period of revocation applicable to such General Release has passed; provided, further, that the General Release shall be made available to Executive no later than five (5) days following the date of Executive’s termination of employment under Sections 7(c) or (f) herein. As shall be further described in the General Release, Executive shall have either twenty- one (21) or forty-five (45) days following receipt of the General Release to consider its execution

.6 6 and seven (7) days following the execution of the General Release to revoke it. If Executive fails to execute the General Release in a timely manner, or revokes the General Release, the benefits provided pursuant to this Section 8(c) (other than the Accrued Obligations) will not be due. 9. Change in Control of Company. (a) Eligibility to Receive Benefits. If a Change in Control (as defined in Section 9(c)) occurs, Executive shall be entitled to the benefits provided in Section 9(b) if, prior to the expiration of twelve (12) months after the Change in Control (i) Executive terminates employment with the Company for Good Reason in accordance with the requirements of Section 7(f) or (ii) the Company terminates Executive’s employment without Cause pursuant to Section 7(c). (b) Receipt of Benefits. If Executive is entitled to receive benefits pursuant to Section 9(a) hereof, Executive shall receive, in addition to the Accrued Obligations: (i) severance pay in an amount equal to: (a) 100% of the Executive’s highest annualized Base Salary in effect on any date during the Initial Term or any Renewal Term, and (ii) any incentive compensation earned, in accordance with the applicable terms and conditions of the Incentive Plan, in the calendar year prior to termination of employment that has not been paid to Executive and a prorated portion (based on the number of calendar days that have elapsed during the year) of the payment to which Executive would be entitled under the Incentive Plan (had Executive’s employment not been terminated) for the calendar year in which Executive’s employment is terminated; (iii) Executive shall be entitled to continue to receive life, disability, accident and group health and dental insurance benefits, at substantially the levels Executive was receiving immediately prior to Executive’s termination of employment, for a period of time expiring upon the earlier of: (1) the end of the period of twelve (12) months following Executive’s Separation from Service, or (2) the day on which Executive becomes eligible to receive any substantially similar benefits under any plan or program of any other employer or source without being required to pay any premium with respect thereto. Company may satisfy the obligation to provide the health and dental insurance benefits pursuant to this Section 9(b)(ii) by either paying for or reimbursing Executive for the actual cost of COBRA coverage (and Executive shall cooperate with Company in all respects in securing and maintaining such benefits, including exercising all appropriate COBRA elections and complying with all terms and conditions of such coverage in a manner to minimize the cost). Similarly, Company will reimburse Executive for the cost of comparable coverage for all other insurance benefits that are not subject to the COBRA continuation rules. It will be Executive’s responsibility to procure such benefits, and Company will promptly reimburse Executive for the premiums for such benefits in the specified amount upon Executive’s submission of an invoice or other acceptable proof of payment. Company’s obligation under this paragraph will cease with respect to a particular type of coverage when and if Executive becomes eligible to receive substantially similar coverage with a successor employer;

.6 7 (iv) Executive shall be vested in any and all equity-based plans and agreements of Company in which Executive had an interest, vested or contingent. If applicable law prohibits such vesting, then Company shall pay to Executive in a single lump sum cash payment in an amount equal to the value of benefits and rights that would have, but for such prohibition, been vested in Executive. (v) Subject to Section 15 herein, the benefits provided pursuant to this Section 9(b) (other than the Accrued Obligations) will be paid in a single lump sum on the Company’s first regular payday that falls at least sixty (60) days following Executive’s termination of employment; provided that (1) Executive has timely executed (and not revoked) a General Release and (2) any period of revocation applicable to such General Release has passed; provided, further, that the General Release shall be made available to Executive no later than five (5) days following the date of Executive’s termination of employment under Sections 7(c) or (f) herein. As shall be further described in the General Release, Executive shall have either twenty-one (21) or forty-five (45) days following receipt of the General Release to consider its execution and seven (7) days following the execution of the General Release to revoke it. If Executive fails to execute the General Release in a timely manner, or revokes the General Release, the benefits provided by this Section 9(b) (other than the Accrued Obligations) will not be due. The Incentive Plan payments to which Executive is entitled for the year or quarter of the Executive’s termination shall be made within the time period described in the applicable Incentive Plan, provided Executive has timely executed and not revoked a General Release as described above. In no event will the Incentive Plan payments be made later than March 15 of the year following the year in which Executive’s employment is terminated. (c) Change in Control Defined. For purposes of this Agreement, “Change in Control” shall have the meaning set forth in the Equity Plan. (d) Cap on Payments. (i) General Rules. The Internal Revenue Code (the “Code”) imposes significant tax consequences on Executive and Company if the total payments made to Executive due, or deemed due, to a “change in control” (as such term is defined in Section 280G(b)(2)(A)(i) of the Code and the regulations adopted thereunder) exceed prescribed limits. For example, if Executive’s “Base Period Income” is $100,000 and Executive’s “Total Payments” exceed 299% of such Base Period Income (the “Cap”), Executive will be subject to an excise tax under Section 4999 of the Code of 20% of all amounts paid to Executive in excess of $100,000. In other words, if Executive’s Cap is $299,999, Executive will not be subject to an excise tax if Executive receives exactly $299,999. If Executive receives $300,000, Executive will be subject to an excise tax of $40,000 (20% of $200,000). (ii) Reduction of Payments. Subject to the exception described in Section 9(d)(iii), in order to avoid the excise tax imposed by Section 4999 of the Code, one or more of the payments or benefits to which Executive is entitled that is not subject to Section 409A of the Code shall be reduced until the Total Payments equal the Cap. For purposes of this limitation:

.6 8 (1) No portion of the Total Payments shall be taken into account which, in the opinion of the Consultant retained pursuant to Section 9(d)(iv), does not constitute a “parachute payment” within the meaning of Section 280G(b)(2) of the Code; (2) A payment shall be reduced only to the extent necessary so that the Total Payments constitute reasonable compensation for services actually rendered within the meaning of Section 280G(b)(4) of the Code or are otherwise not subject to disallowance as deductions, in the opinion of the Consultant; and (3) The value of any non-cash benefit or any deferred payment of benefit included in the Total Payments shall be determined in accordance with Section 280G of the Code and the regulations issued thereunder. (4) If after the reductions called for by the preceding provisions of this Section 9(d)(ii), the Total Payments continue to exceed the Cap, the payments or benefits to which, Executive is entitled and which are subject to Section 409A shall be reduced proportionally until the Total Payments equal the Cap. (iii) Exception. The payment limitation called for by Section 9(d)(ii) shall not apply if Executive determines that Executive would prefer to receive the “Uncapped Benefit” rather than reduce the Total Payments in the manner outlined in Section 9(d)(ii). In the event Executive elects to receive the Uncapped Benefit, Executive will be solely responsible for any excise tax imposed by Section 4999 of the Code. The Consultant selected pursuant to Section 9(d)(iv) will calculate Executive’s Uncapped Benefit and Executive’ s Capped Benefit. For this purpose, the “Uncapped Benefit” is equal to the Total Payments to which Executive is entitled prior to the application of Section 9(d)(ii). Executive’s “Capped Benefit” is the amount to which Executive will be entitled after application of the limitations of Section 9(d)(ii). (iv) Consultant. Company will retain a “Consultant” to advise Company with respect to the applicability of any Section 4999 excise tax with respect to Executive’s Total Payments. The Consultant shall be a law firm, a certified public accounting firm, and/or a firm nationally recognized as providing executive compensation consulting services. All determinations concerning Executive’s Capped Benefit and Executive’s Uncapped Benefit (as well as any assumptions to be used in making such determinations) shall be made by the Consultant selected pursuant to this Section 9(d)(iv). The Consultant shall provide Executive and Company with a written explanation of its conclusions. All fees and expenses of the Consultant shall be borne by Company . The Consultant’s determination shall be binding on Executive and Company. (v) Special Definitions. For purposes of this Section 9(d), the following specialized terms will have the following meanings: (1) “Base Period Income.” “Base Period Income” is an amount equal to Executive’ s “annualized includable compensation” for the “base period’’ as defined in Sections 280G(d)(l) and (2) of the Code and the regulations adopted thereunder. Generally, Executive ‘s “annualized includable compensation” is the average of Executive’s

.6 9 annual taxable income from Company for the “base period,” which is the five (5) calendar years prior to the year in which the change in control occurs. (2) “Cap” or “280G Cap.” “Cap” or “280G Cap” shall mean an amount equal to 2.99 times Executive’ s Base Period Income. This is the maximum amount which Executive may receive without becoming subject to the excise tax imposed by Section 4999 of the Code or which Company may pay without loss of deduction under Section 280G of the Code. (3) “Total Payments.” The “Total Payments” include any “payments in the nature of compensation” (as defined in Section 280G of the Code and the regulations adopted thereunder), made pursuant to this Agreement or otherwise, to or for Executive’s benefit, the receipt of which is contingent or deemed contingent on a change in control and to which Section 280G of the Code applies. (vi) Effect of Repeal. In the event that the provisions of Sections 280G and 4999 of the Code are repealed without succession, Section 9(d) shall be of no further force or effect. (vii) Employment by Successor. For purposes of this Agreement, employment by a successor of Company or a successor of any subsidiary of Company that has assumed this Agreement shall be considered to be employment by Company or one of its subsidiaries. As a result, if Executive is employed by such a successor following a Change in Control, Executive will not be entitled to receive the benefits provided by Section 9 unless Executive’s employment with the successor is subsequently terminated without Cause or for Good Reason within twelve (12) months following the Change in Control. 10. Confidentiality, Intellectual Property, Non-Solicitation, and Non-Competition Agreement. As a condition of employment, Executive also must sign the Confidentiality, Intellectual Property, Non-Solicitation and Non-Competition Agreement, which is attached as Exhibit A to this Agreement. 11. Applicable Law. This Agreement and any disputes or claims arising hereunder shall be construed in accordance with, governed by and enforced under the laws of the State of Arizona without regard for any rules of conflicts of law. 12. Company Policies. (a) General Company Policies. Except where inconsistent with the terms of this Agreement, Executive agrees that Executive will be subject to, and comply with, the employment policies and procedures established by the Company from time to time. (b) Company Stock Ownership Guidelines. Executive agrees that Executive will be subject to the Company’s stock ownership guidelines. (c) Clawback. To the extent required by law or Company policy, the Company may require Executive to repay to the Company any bonus or other incentive-based or equity- based compensation paid to Executive.

.6 10 13. Section 16 of the Securities Exchange Act. If, at the time Executive’s employment is terminated for any reason, Executive is a person designated to file pursuant to Section 16 of the Securities Exchange Act of 1934 (the “1934 Act”), Executive will provide to the Company a written representation in a form acceptable to the Company that all reportable pre- termination securities transactions relating to Executive have been reported. 14. Withholding. The Company may effect withholdings from the payments due to Executive under this Agreement for the payment of taxes and other lawful withholdings or required employee contributions, in accordance with applicable law. 15. Section 409A. (a) It is the intention of the Company and Executive that this Agreement not result in unfavorable tax consequences to Executive under Section 409A of the Code (“Section 409A”). To the extent applicable, it is intended that the Agreement comply with the provisions of Section 409A, but the Company does not warrant or guarantee that the Agreement is either excepted from the requirements of Section 409A or that the Agreement complies with Section 409A. The Agreement will be administered and interpreted in a manner consistent with this intent, and any provision that would cause the Agreement to fail to satisfy Section 409A will have no force and effect until amended to comply therewith (which amendment may be retroactive to the extent permitted by Section 409A). The Company and Executive agree to work together in good faith in an effort to comply with Section 409A including, if necessary, amending this Agreement based on further guidance issued by the Internal Revenue Service from time to time, provided that the Company shall not be required to assume any increased economic burden. Executive remains solely responsible for any adverse tax consequences imposed upon Executive by Section 409A. (b) Notwithstanding anything contained herein to the contrary, to the extent required in order to avoid accelerated taxation and/or tax penalties under Section 409A, Executive shall not be considered to have terminated employment with the Company for purposes of the Agreement and no payments shall be due to Executive under the Agreement which are payable upon his termination of employment until Ee would be considered to have incurred a “separation from service” from the Company within the meaning of Section 409A. (c) To the extent required in order to avoid accelerated taxation and/or tax penalties under Section 409A, amounts that would otherwise be payable and benefits that would otherwise be provided upon Executive’s termination of employment pursuant to the Agreement during the six-month period immediately following Executive’s termination of employment shall instead be paid within thirty (30) days following the first business day after the date that is six months following his termination of employment (or upon his death, if earlier). If it is determined that all or a portion of the payments due pursuant to this Agreement are subject to Section 409A of the Code, and if the General Release consideration period and revocation period spans two calendar years, the payments provided pursuant to this Agreement that are subject to Section 409A shall not begin until the second calendar year. Executive may not elect the taxable year of the distribution. In addition, for purposes of this Agreement, each amount to be paid or benefit to be provided to the Executive pursuant to this Agreement shall be construed as a separate identified payment for purposes of Section 409A.

.6 11 (d) 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 the Company 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. 16. Dispute Resolution. The Parties agree that any controversy, dispute or claim arising out of or relating to the Agreement or breach thereof, including without limitation Executive’s employment with or separation of employment from Company, and all claims, to the extent allowable by law, that Company or any of its representatives engaged in conduct prohibited on any basis under any federal, state, or local statute, including federal or state discrimination statutes or public policy, shall be resolved by final, binding and conclusive arbitration in Maricopa County, Arizona, with a sole arbitrator to be mutually agreed upon by the Parties. The Parties shall bear equally the cost of the arbitrator. The arbitration shall occur within thirty (30) days of selection of the arbitrator and shall be administered by the American Arbitration Association under its Employment Arbitration Rules and judgment upon the award rendered by the arbitrator may be entered in any court having jurisdiction thereof. Any arbitration award may, in the discretion of the arbitrator, include reasonable attorneys’ fees and costs of the prevailing party. “Attorneys’ fees and costs” mean all reasonable pre-award expenses, administrative fees, travel expenses, out- of-pocket expenses such as copying and telephone costs, witness fees and attorneys’ fees. Any award of attorney’s fees and costs to which Executive may be entitled shall be paid by Company, on or before December 31 of the calendar year following the year of the conclusion of the arbitration. Either party may apply to the arbitrator to seek injunctive relief until the arbitration award is rendered or the matter is otherwise resolved. Either party also may, without waiving any remedy under the Agreement, seek from any court having jurisdiction any interim or provisional relief, including a temporary restraining order, an injunction both preliminary and final, and any other appropriate equitable relief, that is necessary to protect the rights or property of that party, pending the retention of the arbitrator. 17. No Conflict. Executive hereby represents and warrants that Executive is under no conflicting duty or contractual or other legal obligation that would prevent Executive from executing this Agreement or performing the duties of Senior Vice President, General Counsel and Corporate Secretary for the Company. 18. No Waivers. The failure of either party to enforce any provision of this Agreement shall not be construed as a waiver of any such provision, nor prevent such party thereafter from enforcing such provision or any other provision of this Agreement. Rights granted the parties hereto herein are cumulative and the election of one shall not constitute a waiver of such party’s right to assert all other legal remedies available under the circumstances. 19. Notices. All notices or other communications hereunder shall be in writing and shall be deemed to have been duly given (i) when delivered personally or by local courier, (ii) upon confirmation of receipt when such notice or other communication is sent by facsimile, or (iii) one

.6 12 day after timely delivery to an overnight delivery courier. The addresses for such notices shall be as follows: TO THE COMPANY: Insight Enterprises, Inc. Attn: Chief Executive Officer 2701 E. Insight Way Chandler, Arizona 85286 TO EXECUTIVE: At the most recent address on file in the records of the Company. 20. Severability. The provisions of this Agreement are severable and if any provision of this Agreement shall be held to be invalid or otherwise unenforceable, in whole or in part, the remainder of the provisions, or enforceable parts thereof, shall not be affected thereby unless as a result of such severing the remaining provisions or enforceable parts do not substantially reflect the intention of the parties in entering into this Agreement. 21. Successors and Assigns. This is an agreement for personal services and may not be assigned by Executive. The rights and obligations of the parties under this Agreement shall inure to the benefit of and be binding upon their successors, heirs and assigns, including the survivor upon any merger, consolidation or combination of the Company with any other entity. 22. Entire Agreement and Amendments. This Agreement sets forth the entire agreement of the parties hereto and supersedes all prior agreements, negotiations, understandings and covenants (except as otherwise provided herein) with respect to the subject matter hereof, including any offer letter provided to Executive. This Agreement may be amended, modified or canceled only by mutual agreement of the parties and only in writing. 23. Counterparts. This Agreement may be executed in two (2) counterparts, each of which shall be deemed an original and all of which together shall constitute but one and the same instrument. IN WITNESS WHEREOF, the parties have executed this Agreement as of the date first above written. INSIGHT ENTERPRISES, INC.

jurisdiction or arbitrator finds that any provision of this Agreement or its Attachments is invalid or unenforceable, but that by limiting, editing, or revising such language, it would become valid or enforceable, then such provision shall be deemed to be written, construed, and enforced as so limited, edited, or revised. 13. Attorneys’ Fees. In any action seeking, in whole or in part, enforcement of the Agreement, challenging the enforceability of any provision of this Agreement, or for a breach or threatened breach of this Agreement, the prevailing Party will be entitled to recover its attorneys’ fees and costs. 14. Waiver of Rights. If, on one or more occasions, either Party fails to insist that the other Party perform any of the terms of this Agreement, such failure shall not be construed as a waiver by such Party of any past, present, or future right granted under this Agreement, and the obligations of the Parties shall continue in full force and effect. Further, Insight’s failure to seek to enforce a similar agreement with any other Insight employee shall not constitute a waiver of Insight’s rights under this Agreements. 15. Governing Law. Section 3 of this Agreement shall be governed by and interpreted pursuant to the Federal Arbitration Act. Otherwise, the governing law for this Agreement and its Attachments shall be: i) the state in which Employee works if Employee works for Insight in Arizona, California, Florida, Illinois, Ohio, Texas, or Washington, without regard to such state’s conflicts of law principles; or ii) Delaware, without regard to its conflicts of law principles, if Employee works in any state other than those listed in the preceding clause. The Parties agree that, in the event of a dispute, Insight’s records indicating the state of employment for Employee shall be used to determine the governing law. 16. Enforcement of Restrictive Covenants. Employee understands and agrees that the breach by Employee of the restrictive covenants contained in Section 4, 6, or 7 of this Agreement, as more fully defined in Attachments A, B, and C, could not reasonably or adequately be fully compensated in damages in an action at law. Therefore, Insight shall be entitled, without the necessity of showing any actual damages or that money damages would not afford an adequate remedy, and without the necessity of posting bond, to injunctive relief. The injunctive relief may include, but is not limited to, restraining Employee from rendering any service or making any disclosure that would breach any restrictive covenant in this Agreement. If Insight is successful in obtaining such injunctive relief, the duration of the restrictive covenant shall be tolled and computed from the date such relief is granted, reduced by the time period between termination of Employee’s employment and the date of the first breach by Employee. No remedy conferred by this Agreement (including this Section) is intended to be exclusive of any other remedy. Each and every remedy shall be cumulative and shall be in addition to every other remedy given hereunder, or now or hereafter existing in law or in equity, by statute or otherwise. The election of any one or more remedies by Insight shall not constitute a waiver of the right to pursue other available remedies. To the extent that any of the restrictive covenants contained in this Agreement conflict with any of Employee’s obligations in Insight’s compensation or equity plan agreements or plans, or contained in any separate agreements that Employee signed with Insight regarding the treatment

of confidential or proprietary information or containing any restrictive covenants, including, but not limited to, not to compete or not to solicit clients, customers, or employees, Employee acknowledges and agrees that Insight may seek to enforce all such covenants. But in the event of an irreconcilable conflict, Insight may choose, in its sole discretion, which covenant(s) it seeks to enforce. If any of the restrictive covenants contained in Section 4, 6, or 7 of this Agreement are deemed by a court of competent jurisdiction or arbitrator to be unenforceable under applicable law and incapable of being limited, edited, or revised to become valid and enforceable, then the restrictive covenants previously agreed to by Employee and Insight shall remain enforceable. 17. Successors and Assigns – Binding Effect. This Agreement shall not be assignable by Employee. The rights and obligations of the Parties under this Agreement shall be binding upon and shall inure to the benefit of Insight and Insight’s successors and assigns. This Agreement may be enforced by Insight’s assignee or successor. 18. Survival. Employee understands and agrees that the obligations, commitments, undertakings, and covenants set forth in this Agreement, including but not limited to those set forth in Sections 3, 4, 5, 6, 7 and 8 shall survive the termination of Employee’s employment with Insight. 19. Voluntary Agreement; Legal Review; Counterparts. Employee agrees that Employee: i) has read and understands this Agreement and its Attachments in their entirety; ii) may before signing this Agreement, if Employee desires, obtain advice from legal counsel of Employee’s choice to advise Employee on this Agreement; iii) has freely and voluntarily entered into this Agreement; and iv) understands this Agreement may be signed separately by each Party, electronically or physically, and may be transmitted via PDF, facsimile, or otherwise, and each signature page when combined with a copy of the preceding pages of this Agreement shall constitute the full agreement.
