WHEREAS, Executive served the Company as its Chief Technology Officer and Executive Vice President of Products from October 2018 to August of 2019, and was promoted to Chief Executive Officer of Silvaco Inc. In March of 2021 to August 27, 2021 he was the CEO, CTO and board member of the Silvaco Group. On August 27, 2021, Executive’s employment with the Company terminated (the “Termination Date”); and

WHEREAS, Executive has resigned his position as a Director of the Company, as well as all other positions held with the Company and its subsidiaries and affiliates, pursuant to the resignation letter attached as Exhibit A, and effective as of the Termination Date; and

WHEREAS, the Company and Executive entered into an Employee Proprietary Information and Inventions Agreement dated July 13, 2021 (the “Confidentiality Agreement”); and

WHEREAS, the Company wishes to provide Executive with a severance package, but is willing to do so only if Executive provides the Company with this release so that the Company is assured that the severance pay satisfies Executive’s expectations.

NOW, THEREFORE, in consideration of the promises made herein, the Parties hereby agree as follows:

1.Consideration. In consideration of Executive’s execution of this Agreement and Executive’s fulfillment of all of its terms and conditions, and provided that Executive does not revoke the Agreement under Section 9 below, the Company agrees as follows:

(a)    Separation Pay. The Company agrees to pay Executive the gross amount of Three Hundred Sixty Thousand dollars ($360,000.00) (“Separation Pay”), payable as follows:

(i)    The first payment of One Hundred Eighty Thousand dollars ($180,000.00), less applicable payroll withholding, will be made on or before the twentieth (20th) day following the Effective Date of this Agreement (as defined in Section 9 below); and

(ii)    The second payment of One Hundred Eighty Thousand dollars ($180,000.00), less applicable payroll withholding, will be made on or about February 28, 2022, six months after the Termination Date.

(b)    COBRA. If and to the extent that Executive elects to continue health insurance coverage under COBRA, then for the months of September 2021 through February 2022, so long as Executive remains eligible, the Company agrees to pay the entire monthly COBRA premiums for Executive and his dependents at the same coverage level prior to the Termination Date. Executive is solely responsible for timely filing any necessary paperwork for COBRA coverage. Executive agrees promptly to notify the Company if he becomes ineligible for continued COBRA coverage during the specified period.

(c)    General. Executive acknowledges that without this Agreement, he is not otherwise entitled to the consideration listed in this Section 1, which is offered by the Company solely as consideration for this Agreement.

2.Benefits. Executive’s company-provided health insurance benefits will cease on August 31, 2021, subject to Executive’s right to continue his health insurance under COBRA (see Section 1(b) above). Except as specified in this Agreement, Executive’s participation in all benefits and incidents of employment, including, but not limited to, the accrual of any bonuses, PTO, and RSU service vesting, will cease as of the Termination Date.

3.Restricted Stock Units. At various times during the term of Executive’s employment, the Company granted Executive certain Liquidity Contingent Restricted Stock Units (“RSUs”) pursuant to its 2014 Stock Incentive Plan and applicable Restricted Stock Unit Award Agreements, which plan and agreements shall continue to govern the treatment and disposition of Executive’s RSU awards as described herein. As summarized in Exhibit B hereto: (a) Executive has service-vested in 70,000 RSUs that are not subject to the claw-back provision set forth in the 2014 Stock Incentive Plan and Restricted Stock Unit Award Agreements, and (b) as of the Termination Date, Executive will have service-vested in an additional 87,500 RSUs that are subject to the claw-back provision set forth in the 2014 Stock Incentive Plan and Restricted Stock Unit Award Agreements. Executive agrees and acknowledges that (i) the vesting of the RSUs is subject to two conditions, i.e., the completion of a time based service-vesting schedule and the occurrence of a liquidity event as defined by the Board of Directors for purposes of such RSUs (“Liquidity Event”) before the expiration of the remaining term of the RSUs or such earlier expiration date following termination of employment as may be specified in a claw-back provision in the applicable Restricted Stock Unit Award Agreement, (ii) none of the RSUs have vested as of the Termination Date, (iii) Executive will forfeit as of the Termination Date all RSUs that have not service-vested as of such date, and (iv) Executive will forfeit all service-vested RSUs if the Company does not have a Liquidity Event before the applicable expiration date. Executive further agrees and acknowledges that he is not entitled to any common shares or other securities of the Company (other than pursuant to those RSUs in which he has service-vested as of the Termination Date as summarized in Exhibit B hereto if and only to the extent they become vested upon a Liquidity Event before the applicable expiration date as described above).

4.Trade Secrets and Confidential Information/Company Property. Executive reaffirms and agrees to observe and abide by the terms of the Confidentiality Agreement. Further, Executive’s signature below constitutes his certification that he has returned all

documents and other items in whatever form or format, provided to Executive by the Company (excluding only payroll and personnel records and other similar documents to which Executive is entitled), developed or obtained by Executive in connection with his employment or any other affiliation with the Company, or otherwise belonging to the Company. Except as may be required by law, subpoena or court order, Executive and the Company further agree to keep the contents of this Agreement, and the negotiations leading up to it, confidential and will not disclose it to third parties (with the exception of immediate family members, attorneys, accountants and financial advisors).

5.Payment of Salary and Receipt of All Benefits. Executive acknowledges and represents that, other than the consideration set forth in this Agreement, the Company has paid or provided all salary, wages, bonuses, accrued vacation/paid time off, leave, housing allowances, relocation costs, interest, severance, outplacement costs, fees, reimbursable expenses, commissions, stock, stock options, vesting, and any and all other benefits and compensation due to Executive.

6.Company Release of Claims. The Company, on behalf of itself and all of its current and former officers, directors, employees, agents, investors, attorneys, shareholders, founders, administrators, affiliates, divisions, subsidiaries, predecessor and successor corporations and assigns, hereby and forever releases Executive and his respective heirs, family members, executors, agents, and assigns (“Executive Releasees”), from, and agrees not to sue concerning, or in any manner to institute, prosecute or pursue, any claim, complaint, charge, duty, obligation or cause of action relating to any matters of any kind, whether presently known or unknown, suspected or unsuspected, that the Company may possess against any of the Executive Releasees arising from any omissions, acts or facts or damages that have occurred up until and including the Effective Date of this Agreement including, without limitation (i) any and all claims relating to or arising from Executive’s employment relationship with the Company and the termination of that relationship, (ii) any and all claims relating to or arising from Executive’s right to vest in or purchase RSUs or other equities of the Company; and (iii) any and all claims for attorneys’ fees and costs. Notwithstanding the foregoing, the Company does not intend to waive, and does not waive, any claims against Executive arising as a result of Executive’s employment-related conduct that results in federal or state criminal liability. The Company agrees that the release set forth in this Section shall be and remain in effect in all respects as a complete general release as to the matters released. This release does not extend to any obligations incurred under this Agreement.

7.Executive Release of Claims. Executive agrees that the foregoing consideration represents settlement in full of all outstanding obligations owed to Executive by the Company and its current and former officers, directors, employees, agents, investors, attorneys, shareholders, founders, administrators, affiliates, divisions, subsidiaries, predecessor and successor corporations and assigns (the “Company Releasees”). Executive, on his own behalf, and on behalf of his respective heirs, family members, executors, agents, and assigns, and in his capacity as an individual and as a representative of any purported class, hereby and forever releases the Releasees from, and agrees not to sue concerning, or in any manner to institute, prosecute or pursue, any claim, complaint, charge, duty, obligation or cause of action relating to

any matters of any kind, whether presently known or unknown, suspected or unsuspected, that Executive may possess against any of the Releasees arising from any omissions, acts or facts or damages that have occurred up until and including the Effective Date of this Agreement including, without limitation:

(a)    any and all claims relating to or arising from Executive’s employment relationship with the Company and the termination of that relationship;

(b)    any and all claims relating to or arising from Executive’s right to vest in or purchase RSUs or other equities of the Company, including, without limitation, any claims for fraud, misrepresentation, breach of fiduciary duty, breach of duty under applicable state corporate law, and securities fraud under any state or federal law;

(d)    any and all claims for violation of any federal, state or municipal statute, including, but not limited to, Title VII of the Civil Rights Act of 1964; the Civil Rights Act of 1991; the Age Discrimination in Employment Act of 1967 (29 U.S.C. § 621 et seq.); the Americans with Disabilities Act of 1990; the Fair Credit Reporting Act; the Employee Retirement Income Security Act of 1974; the Family and Medical Leave Act; the Worker Adjustment and Retraining Notification Act; the Older Workers Benefit Protection Act; the Sarbanes-Oxley Act of 2002; the Fair Labor Standards Act (29 U.S.C. §201 et seq.); relevant California labor codes, and all amendments to each of the above-referenced statutes; any other laws of the state of California; and any other federal, state or local laws or regulations relating to employment terms and conditions of employment;

(e)    any and all claims for violation of the federal, or any state, constitution;

(f)    any and all claims arising out of any other laws and regulations relating to employment or employment discrimination;

(i)    Executive agrees that the release set forth in this Section shall be and remain in effect in all respects as a complete general release as to the matters released. This release does not extend to any obligations incurred under this Agreement. This release does not release

claims that cannot be released as a matter of law, including but not limited to Executive’s right to file a charge with or participate in a charge by the Equal Employment Opportunity Commission, or any other local, state, or federal administrative body or government agency that is authorized to enforce or administer laws related to employment, against the Company (with the understanding that any such filing or participation does not give Executive the right to recover any monetary damages against the Company; Executive’s release of claims herein bars Executive from recovering such monetary relief from the Company). This release also does not release (i) any claims for indemnification that Executive may have against the Company or the Releasees under any indemnification agreement or other arrangement with the Company or the Releasees, or under applicable law or (ii) any right to coverage under any D&O or other similar insurance policy.

8.Additional Effects of Release. Without limiting the generality of the forgoing, Executive agrees that as a result of his resignation from employment as described herein, Executive has no right to severance benefits of any type, other than as set forth herein, and expressly waives and releases any rights to severance or other benefits under his offer letter dated September 21, 2018 (which is hereby expressly terminated) or any other agreement with, or policy or practice of, the Company.

9.Acknowledgement of Waiver of Claims Under ADEA. Executive acknowledges that he is waiving and releasing any rights he may have under the Age Discrimination in Employment Act of 1967 (“ADEA’’), and that this waiver and release is knowing and voluntary. Executive agrees that this waiver and release does not apply to any rights or claims that may arise under the ADEA after the Effective Date of this Agreement. Executive acknowledges that the consideration given for this waiver and release is in addition to anything of value to which Executive was already entitled.

Executive further acknowledges that he has been advised by this writing that:

(a)    he should consult with an attorney prior to executing this Agreement;

(b)    he has twenty-one (21) days within which to consider and accept the terms of this Agreement.

(d)    if Executive does not revoke during the seven-day Revocation Period, this Agreement will take effect on the eighth (8th) day after the date Executive signs the Agreement (“Effective Date”); and

(e)    nothing in this Agreement prevents or precludes Executive from challenging or seeking a determination in good faith of the validity of this waiver under the ADEA, nor does it impose any condition precedent, penalties, or costs for doing so, unless specifically authorized by federal law. In the event Executive signs this Agreement and returns it to the Company in less than the 21-day period identified above, Executive hereby acknowledges that he has freely and voluntarily chosen to waive the time period allotted for considering this Agreement.

Executive represents that Executive has no lawsuits, claims, administrative actions or otherwise pending in his name, or on behalf of any other person or entity, against the Company or any of the other Releasees.
