Re: NAPCO Security Technologies, Inc. (the “Company”) - Restriction on Stock Sales

This letter agreement is delivered to you pursuant to the Underwriting Agreement (the “Underwriting Agreement”) to be entered into by the Company, Richard L. Soloway, as selling stockholder, and B. Riley Securities, Inc., representative of the underwriters (the “Representative”). Upon the terms and subject to the conditions of the Underwriting Agreement, the Underwriters intend to effect a public offering of shares of Common Stock, $0.01 par value per share, of the Company (the “Shares”), as described in and contemplated by the registration statement of the Company on Form S-3, File No. 333-248078 (the “Registration Statement”), initially filed with the Securities and Exchange Commission (the “SEC”) on August 17, 2020 and declared effective by the SEC on August 24, 2020 (the “Offering”). Terms used herein, but not defined, shall have the meaning ascribed to them in the Underwriting Agreement.

The undersigned recognizes that it is in the best financial interests of the undersigned, as an officer or director, or an owner of Common Stock, options, warrants, performance units or other securities convertible into or exchangeable for Common Stock of the Company (the “Company Securities”), that the undersigned not sell Company Securities in the public market for a reasonable period following the Offering.

The undersigned further recognizes that the Company Securities held by the undersigned are, or may be, subject to certain restrictions on transferability, including those imposed by United States federal securities laws. Notwithstanding these restrictions, the undersigned has agreed to enter into this letter agreement to further assure the Underwriters that the Company Securities of the undersigned, now held or hereafter acquired, will not enter the public market at a time that might impair the underwriting effort.

Therefore, as an inducement to the Underwriters to execute the Underwriting Agreement, the undersigned hereby acknowledges and agrees that the undersigned will not, without the prior written consent of the Representative, (1) offer, sell, contract to sell, pledge, grant any option to purchase or otherwise dispose of (collectively, a “Disposition”) any Company Securities or any securities convertible into or exercisable or exchangeable for, or any rights to purchase or otherwise acquire, any Company Securities held by the undersigned or acquired by the undersigned after the date hereof, or that may be deemed to be beneficially owned by the undersigned (collectively, the “Lock-Up Shares”), pursuant to the Rules and Regulations promulgated under the Securities Act of 1933, as amended (the “Act”), and the Securities Exchange Act of 1934, as amended (the “Exchange Act”), for a period commencing on the date hereof and ending 60 days after the date of the Underwriting Agreement, inclusive (the “Lock-Up Period”), (2) during the Lock-Up Period, exercise or seek to exercise or effectuate in any manner any rights of any nature that the undersigned has or may have hereafter to require the Company to register under the Act the undersigned’s Disposition of any of the Lock-Up Shares held by the undersigned, (3) otherwise participate as a selling securityholder in any manner in any registration of Lock-Up Shares effected by the Company under the Act, except with respect to the Lock-Up Shares registered under the Registration Statement in connection with the Offering, during the Lock-Up Period, or (4) engage in any hedging, collar (whether or not for any consideration) or other transaction that is designed to or reasonably expected to lead to or result in a Disposition of Lock-Up Shares during the Lock-Up Period, even if such Lock-Up Shares would be disposed of by someone other than such holder, and such prohibited hedging or other transactions would include any short sale or any purchase, sale or grant of any right (including any put or call option or reversal or cancellation thereof) with respect to any Lock-Up Shares or with respect to any security (other than a broad-based market basket or index) that includes, relates to or derives any significant part of its value from Lock-Up Shares.

1

Notwithstanding the agreement not to make any Disposition during the Lock-Up Period, the Underwriters have agreed that the foregoing restrictions shall not apply to:

(1) any Disposition or transfer of Lock-Up Shares to a family member, trust, or entity in which more than fifty percent of the voting interests are owned by the undersigned or the undersigned’s immediate family members (as defined in General Instruction A.1(a)(5) to Form S-8 under the Act);

(2) any bona fide gift;

(3) any Disposition or transfer of Lock-Up Shares by will, intestate succession or by operation of law pursuant to a qualified domestic order or in connection with a divorce settlement;

(4) any transfer of Lock-Up Shares solely to cover applicable withholding taxes due upon the vesting of stock-based awards under the Company’s equity compensation plans;

(5) the conversion or exchange of convertible or exchangeable Company Securities outstanding as of the date of this letter agreement;

(6) the forfeiture or surrender to the Company of Lock-Up Shares for failure to achieve vesting requirements associated with such Lock-Up Shares;

(7) Dispositions or forfeiture of Lock-Up Shares of the undersigned or the retention of Lock-Up Shares by the Company (A) to satisfy tax withholding obligations in connection with the exercise of options to purchase Shares, the vesting of restricted stock units or performance shares or the settlement of deferred stock units of the Company or (B) in payment of the exercise or purchase price with respect to the exercise of options to purchase Shares, the vesting of restricted stock units or performance shares or the settlement of deferred stock units of the Company;

2

(8) the establishment of a trading plan pursuant to Rule 10b5-1 under the Exchange Act for the transfer of Lock-Up Shares;

(9) the Disposition or transfer of Lock-Up Shares pursuant to a trading plan established pursuant to Rule 10b5-1 under the Exchange Act prior to the date of this letter agreement;

(10) any Disposition or transfer of Lock-Up Shares pursuant to a bona fide third-party tender offer, merger, consolidation or other similar transaction that is approved by the board of directors of the Company, made to all holders of the Company Securities involving a Change of Control (as defined below) (including any support or voting agreement entered into in connection therewith), provided that in the event that the tender offer, merger, consolidation or other such transaction is not completed, the Lock-up Shares of the undersigned shall remain subject to the restrictions contained in this letter agreement; or

(11) any Disposition or transfer of Lock-Up Shares registered under the Registration Statement pursuant to and in connection with the Offering;

provided that in the case of any transfer, gift or other disposition pursuant to the immediately preceding clauses (1) or (2), except in the case of a bona fide gift to a charitable or non-profit organization, the transferee, trust, donee or other recipient agrees to be bound in writing by the terms of this letter agreement prior to such transfer and no filing by any party (donor, donee, transferor or transferee) under the Exchange Act shall be required or shall be voluntarily made in connection with such transfer (other than required filings under Section 16(a) and Section 13(d) or 13(g) of the Exchange Act and any filings made after the expiration of the Lock-Up Period). For purposes of clause (10) above, “Change of Control” shall mean any bona fide third-party tender offer, merger, amalgamation, consolidation or other similar transaction the result of which would be that any “person” (as defined in Section 13(d)(3) of the Exchange Act), or group of persons, other than the Company, becomes the beneficial owner (as defined in Rules 13d-3 and 13d-5 of the Exchange Act) of more than 50% of the total voting power of the voting stock of the Company.

Furthermore, the undersigned may, during the Lock-Up Period, sell shares of Common Stock purchased by the undersigned on the open market following the closing of the Offering if and only if (i) such sales are not required to be reported in any public report or filing under the Exchange Act and (ii) the undersigned does not otherwise voluntarily effect any public report or filing regarding such sales.

It is understood that, if the Underwriting Agreement (other than the provisions thereof that survive termination) shall terminate or be terminated prior to payment for and delivery of the Shares, the obligations under this letter agreement shall automatically terminate. Further, this letter agreement is only authorized to be delivered if the Underwriting Agreement referred to herein is dated on or before February 15, 2021.

3

In furtherance of the foregoing, the Company and its transfer agent and registrar are hereby authorized to decline to make any transfer of Lock-Up Shares if such transfer would constitute a violation or breach of this letter agreement. This letter agreement shall be binding on the undersigned and the respective successors, heirs, personal representatives and assigns of the undersigned. Capitalized terms used but not defined herein have the respective meanings assigned to such terms in the Underwriting Agreement.

Very truly yours,

s/Richard L Soloway
