Ladies and Gentlemen:

We have acted as special counsel to Cadre Holdings, Inc., a Delaware corporation (the “Company”), and the Subsidiary Guarantors (as defined below), in connection with the preparation and filing of a registration statement on Form S-3 (the “Registration Statement”) with the Securities and Exchange Commission (the “Commission”) under the Securities Act of 1933, as amended (the “Securities Act”), relating to the registration for issue and sale by the Company of (A) up to $300,000,000 aggregate offering amount of (i) shares of common stock of the Company, par value $0.0001 per share (the “Common Shares”); (ii) shares of preferred stock of the Company, par value $0.0001 per share (the “Preferred Shares”); (iii) debt securities of the Company (the “Debt Securities”); (iv) warrants of the Company relating to the Common Shares, Preferred Shares or Debt Securities (the “Warrants”); and (v) guarantees (each, a “Subsidiary Guarantee”) by certain of the Company’s subsidiaries (the “Subsidiary Guarantors”); and (B) up to 3,000,000 Common Shares to be offered by certain selling stockholders of the Company (the “Stockholder Shares”). The Common Shares, Preferred Shares, Debt Securities, Warrants and Stockholder Shares may be issued and sold or delivered from time to time as set forth in the Registration Statement, and amendments thereto, the prospectus contained therein (the “Prospectus”) and supplements to the Prospectus (the “Prospectus Supplements”) and pursuant to Rule 415 of the General Rules and Regulations promulgated under the Securities Act (the “Securities Act Rules”).

The Debt Securities will be issued in one or more series pursuant to a base indenture (as amended or supplemented from time to time, the “Indenture”) to be entered into among the Company and a trustee to be named therein (the “Trustee”), and any Subsidiary Guarantors, as applicable.

In our capacity as special counsel to the Company in connection with the matters referred to above, we have examined copies of the following: (i) the Amended and Restated Certificate of Incorporation of the Company currently in effect (the “Amended and Restated Certificate”), (ii) the Amended and Restated By-laws of the Company currently in effect (the “Amended and Restated By-laws”) and certain records of the Company’s and Subsidiary Guarantors’ corporate proceedings as reflected in respective minute books, and (iii) the Registration Statement, including the form of Indenture which is attached as an Exhibit to the Registration Statement, in the form it is to be filed with the Commission on the date hereof. We have also examined such other documents, papers, authorities and statutes as we have deemed necessary to form the basis of the opinions hereinafter set forth.

In addition, we have also assumed that the terms of the Offered Debt Securities (as defined below) and Offered Subsidiary Guarantees (as defined below) will have been established so as not to violate, conflict with or constitute a default under (i) any agreement or instrument to which the Company or the Subsidiary Guarantors or their properties are subject, (ii) any law, rule or regulation to which the Company or the Subsidiary Guarantors are subject, (iii) any judicial or regulatory order or decree of any governmental authority, or (iv) any consent, approval, license, authorization or validation of, or filing, recording or registration with any governmental authority.

We express no opinion as to the validity, legally binding effect or enforceability of any provision of the Indenture, any supplemental indenture, or the Offered Debt Securities that requires or relates to payment of any interest at a rate or in an amount that a court would determine in the circumstances under applicable law to be commercially unreasonable or a penalty or a forfeiture.
