NAPCO SECURITY TECHNOLOGIES, INC

The Company reserves the right to require the Participant, to the fullest extent permitted by applicable law, to appoint such Person as shall be determined by the Administrator in its sole discretion as the Participant’s proxy with respect to all applicable unvested Awards of which the Participant may be the record holder of from time to time to (a) attend all meetings of the holders of the shares of Common Stock, with full power to vote and act for the Participant with respect to such Awards in the same manner and extent that the Participant might were the Participant personally present at such meetings, and (b) execute and deliver, on behalf of the Participant, any written consent in lieu of a meeting of the holders of the shares of Common Stock in the same manner and extent that the Participant might but for the proxy granted pursuant to this sentence.

Section 12. Amendment and Termination.

The Administrator may amend, alter or terminate the Plan, but no amendment, alteration, or termination shall be made that would impair the rights of a Participant under any outstanding Award without such Participant’s consent. Unless the Board determines otherwise, the Board shall obtain approval of the Company’s stockholders for any amendment to the Plan that would require such approval in order to satisfy any rules of the stock exchange on which the Common Stock is traded or other applicable law. The Administrator may amend the terms of any outstanding Award, prospectively or retroactively, but, subject to Section 5 hereof and the immediately preceding sentence, no such amendment shall impair the rights of any Participant without the Participant’s consent; provided that the Administrator may amend the terms of any such Award to take effect retroactively or otherwise, as deemed necessary or advisable for the purpose of conforming the Award to any applicable law, government regulation or stock exchange listing requirement relating to such Award (including, but not limited to, Section 409A of the Code), and by accepting an Award under this Plan, the Participant thereby agrees to any amendment made pursuant to this Section 12 to such Award (as determined by the Administrator) without further consideration or action. Notwithstanding anything to the contrary set forth herein, if a Participant’s termination of employment or service is the result of a termination by the Company or any of its Affiliates (as applicable) for Cause or by the Participant at a time when Cause exists, all outstanding Awards held by such Participant, whether vested or unvested, will be immediately forfeited on such termination date, without payment of any consideration or action on the part of the Participant or the Company.

Section 13. Unfunded Status of Plan.

The Plan is intended to constitute an “unfunded” plan for incentive compensation. With respect to any payments not yet made to a Participant by the Company, nothing contained herein shall give any such Participant any rights that are greater than those of a general creditor of the Company.

Section 14. Withholding Taxes.

Each Participant shall, no later than the date as of which the value of an Award first becomes includible in the gross income of such Participant for purposes of applicable taxes, pay to the Company, or make arrangements satisfactory to the Company regarding payment of, an amount in respect of such taxes up to the maximum statutory rates in the Participant’s applicable jurisdiction with respect to the Award, as determined by the Company. The obligations of the Company under the Plan shall be conditional on the making of such payments or arrangements, and the Company shall, to the extent permitted by law, have the right to deduct any such taxes from any payment of any kind otherwise due to such Participant. Whenever cash is to be paid pursuant to an Award, the Participant shall have the right to have the Company, and the Company shall have the right to, deduct therefrom an amount sufficient to satisfy any applicable withholding tax requirements related thereto as determined by the Company. Whenever Shares or property other than cash are to be delivered pursuant to an Award, the Company shall have the right to require the Participant to remit to the Company in cash an amount sufficient to satisfy any related taxes to be withheld and applied to the tax obligations as determined by the Company; provided, that, with the approval of the Administrator, a Participant may satisfy the foregoing requirement by either (a) electing to have the Company withhold from such delivery Shares or other property, as applicable, or (b) by delivering already owned unrestricted shares of Common Stock, in each case, having a value not exceeding the applicable taxes to be withheld and applied to the tax obligations as determined by the Company. Such withheld Shares or other property or already owned and unrestricted shares of Common Stock shall be valued at their Fair Market Value on the date on which the amount of tax to be withheld is determined and any fractional share amounts resulting therefrom shall be settled in cash. Such an election may be made with respect to all or any portion of the Shares to be delivered pursuant to an award. The Company may also use any other method of obtaining the necessary payment or proceeds, as permitted by law, to satisfy its withholding obligation with respect to any Award as determined by the Company.

Section 15. Transfer of Awards.

Until such time as the Awards are fully vested and/or exercisable in accordance with the Plan or an Award Agreement, no purported sale, assignment, mortgage, hypothecation, transfer, charge, pledge, encumbrance, gift, transfer in trust (voting or other) or other disposition of, or creation of a security interest in or lien on, any Award or any agreement or commitment to do any of the foregoing (each, a “Transfer”) by any holder thereof in violation of the provisions of the Plan or an Award Agreement will be valid, except with the prior written consent of the Administrator, which consent may be granted or withheld in the sole discretion of the Administrator. Any purported Transfer of an Award or any economic benefit or interest therein in violation of the Plan or an Award Agreement shall be null and void ab initio, and shall not create any obligation or liability of the Company, and any Person purportedly acquiring any Award or any economic benefit or interest therein transferred in violation of the Plan or an Award Agreement shall not be entitled to be recognized as a holder of any Shares or other property underlying such Award. Unless otherwise determined by the Administrator in accordance with the provisions of the immediately preceding sentence, an Option or Stock Appreciation Right may be exercised, during the lifetime of the Participant, only by the Participant or, during any period during which the Participant is under a legal disability, by the Participant’s guardian or legal representative.

Neither the adoption of the Plan nor the grant of an Award hereunder shall confer upon any Eligible Recipient any right to continued employment or service with the Company or any Affiliate thereof, as the case may be, nor shall it interfere in any way with the right of the Company or any Affiliate thereof to terminate the employment or service of any of its Eligible Recipients at any time.

Section 17. Effective Date; Effect on Prior Plans.

The Plan was adopted on October 29, 2026, subject to approval by the Company’s stockholders, and became effective on [•], 2026 following such approval (the “Effective Date”). Prior to the Effective Date, the Company had in effect (a) the NAPCO Security Technologies, Inc. 2018 Non-Employee Stock Option Plan, (b) the NAPCO Security Technologies, Inc. 2020 Non-Employee Stock Option Plan and (c) the NAPCO Security Technologies, Inc. 2022 Employee Stock Option Plan (collectively, the “Prior Plans”). On and after the Effective Date, the Prior Plans shall terminate such that no new awards may be granted under the Prior Plans, although awards previously granted and still outstanding under the Prior Plans shall continue to be subject to all terms and conditions of the Prior Plans. If any Shares subject to an award under the Prior Plans are forfeited, cancelled, exchanged or surrendered or if any such award otherwise terminates or expires without a distribution of Shares to the grantee thereof, the Shares with respect to such award shall be retired and shall not become available for Awards under the Plan.

Section 18. Term of Plan.

The Plan shall automatically terminate on the date no Shares remain available for issuance under the Plan, but Awards theretofore granted may extend beyond that date. Further, while no Award shall be granted pursuant to the Plan on or after the tenth (10 th) anniversary of the Effective Date, Awards theretofore granted may extend beyond that date.

Section 19. Securities Matters and Regulations.

(a) Notwithstanding anything herein to the contrary, the obligation of the Company to sell or deliver Common Stock with respect to any Award granted under the Plan shall be subject to all applicable laws, rules and regulations, including all applicable federal and state securities laws, the receipt of all such approvals by governmental agencies as may be deemed necessary or appropriate by the Administrator and the listing requirements of any securities exchange on which the Shares are traded. The Administrator may require, as a condition of the issuance and delivery of certificates evidencing shares of Common Stock pursuant to the terms hereof, that the recipient of such shares make such agreements and representations, and that such certificates bear such legends, as the Administrator, in its sole discretion, deems necessary or advisable.

(b) Each Award is subject to the requirement that, if at any time the Administrator determines that the listing, registration or qualification of Common Stock issuable pursuant to the Plan is required by any securities exchange or under any state or federal law, or the consent or approval of any governmental regulatory body is necessary or desirable as a condition of, or in connection with, the grant of an Award or the issuance of Common Stock, no such Award shall be granted or payment made or Common Stock issued, in whole or in part, unless such listing, registration, qualification, consent or approval has been effected or obtained free of any conditions not acceptable to the Administrator.

(c) In the event that the disposition of Common Stock acquired pursuant to the Plan is not covered by a then current registration statement under the Securities Act and is not otherwise exempt from such registration, such Common Stock shall be restricted against transfer to the extent required by the Securities Act or regulations thereunder, and the Administrator may require a Participant receiving Common Stock pursuant to the Plan, as a condition precedent to receipt of such Common Stock, to represent to the Company in writing that the Common Stock acquired by such Participant is acquired for investment only and not with a view to distribution.

Section 20. Notification of Election Under Section 83(b) of the Code.

If any Participant shall, in connection with the acquisition of Shares under the Plan, make the election permitted under Section 83(b) of the Code, such Participant shall notify the Company of such election, and shall deliver a copy of such election to the Company, in each case, within ten (10) days after filing notice of the election with the Internal Revenue Service.

Section 21. No Fractional Shares.

No fractional Shares shall be issued or delivered pursuant to the Plan. The Administrator shall determine whether cash, other Awards or other property shall be issued or paid in lieu of such fractional Shares or whether such fractional Shares or any rights thereto shall be forfeited or otherwise eliminated.

Section 22. Restrictive Covenants.

The Company operates in a highly sensitive and competitive commercial environment. As part of a Participant’s employment and/or service with the Company and its Affiliates, such Participant will be exposed to highly confidential and sensitive information regarding the Company’s business operations, including corporate strategy, pricing and other market information, know-how, trade secrets and valuable customer, supplier, strategic partner, licensee, licensor, lessor, regulatory and employee relationships. It is critical that the Company take all necessary steps to safeguard its legitimate protectable interests in such information and to prevent any of its competitors or any other Persons from obtaining any such information. Therefore, as consideration for the Company’s agreement to grant any Award to any Participant, the Company may require such Participant to agree to be bound by the restrictive covenants set forth in an Award Agreement.

Section 23. Beneficiary.

A Participant may file with the Company a written designation of a beneficiary on such form as may be prescribed by the Company and may, from time to time, amend or revoke such designation. If no designated beneficiary survives the Participant, the executor or administrator of the Participant’s estate shall be deemed to be the Participant’s beneficiary.

Section 24. Paperless Administration.

In the event that the Company establishes, for itself or using the services of a third party, an automated system for the documentation, granting or exercise of Awards, such as a system using an internet website or interactive voice response, then the paperless documentation, granting or exercise of Awards by a Participant may be permitted through the use of such an automated system.

Section 25. Severability.

If any provision of the Plan is held to be invalid or unenforceable, the other provisions of the Plan shall not be affected but shall be applied as if the invalid or unenforceable provision had not been included in the Plan.

Section 26. Clawback.

Notwithstanding any other provisions in this Plan, any Award which is subject to recovery under any law, government regulation or stock exchange listing requirement, will be subject to such deductions and clawback as may be required to be made pursuant to such law, government regulation or stock exchange listing requirement (or the Company’s Incentive Compensation Clawback Policy or any other policy adopted by the Company pursuant to or in connection with any such law, government regulation or stock exchange listing requirement).

Section 27. Section 409A of the Code.

The Plan as well as payments and benefits under the Plan are intended to be exempt from, or to the extent subject thereto, to comply with Section 409A of the Code, and, accordingly, to the maximum extent permitted, the Plan shall be interpreted in accordance therewith. Notwithstanding anything contained herein to the contrary, to the extent required in order to avoid accelerated taxation and/or tax penalties under Section 409A of the Code, the Participant shall not be considered to have terminated employment or service with the Company for purposes of the Plan and no payment shall be due to the Participant under the Plan or any Award until the Participant would be considered to have incurred a “separation from service” from the Company and its Affiliates within the meaning of Section 409A of the Code. Any payments described in the Plan that are due within the “short term deferral period” as defined in Section 409A of the Code shall not be treated as deferred compensation unless applicable law requires otherwise. Notwithstanding anything to the contrary in the Plan, to the extent that any Awards (or any other amounts payable under any plan, program or arrangement of the Company or any of its Affiliates) are payable upon a separation from service and such payment would result in the imposition of any individual tax and penalty interest charges imposed under Section 409A of the Code, the settlement and payment of such awards (or other amounts) shall instead be made on the first business day after the date that is six (6) months following such separation from service (or upon the Participant’s death, if earlier). Each amount to be paid or benefit to be provided under this Plan shall be construed as a separate identified payment for purposes of Section 409A of the Code. The Administrator shall have the sole authority to make any accelerated distributions permissible under Treas. Reg. Section 1.409A-3(j)(4) to Participants with respect to any deferred amounts, provided, that, such distributions meet the requirements of Treas. Reg. Section 1.409A-3(j)(4). The Company makes no representation that any or all of the payments or benefits described in this Plan will be exempt from or comply with Section 409A of the Code and makes no undertaking to preclude Section 409A of the Code from applying to any such payment. The Participant shall be solely responsible for the payment of any taxes and penalties incurred under Section 409A of the Code.

Section 28. Governing Law.

The Plan shall be governed by and construed in accordance with the laws of the State of Delaware, without giving effect to the principles of conflicts of law of such state.

Section 29. Titles and Headings.

The titles and headings of the sections in the Plan are for convenience of reference only and, in the event of any conflict, the text of the Plan, rather than such titles or headings, shall control.

Section 30. Successors.

The obligations of the Company under the Plan shall be binding upon any successor corporation or organization resulting from the merger, consolidation or other reorganization of the Company, or upon any successor corporation or organization succeeding to substantially all of the assets and business of the Company.

Section 31. Relationship to Other Benefits.

No payment pursuant to the Plan shall be taken into account in determining any benefits under any pension, retirement, savings, profit sharing, group insurance, welfare or other benefit plan of the Company or any Affiliate except to the extent otherwise expressly provided in writing in such other plan or an agreement thereunder.
