Board of Directors

CPS Technologies Corp.

Norton, MA 02766

Dear Frank, Dan, Tom and Grant,

I am writing to you on behalf of the Horton Capital Partners Fund, L.P. (the “Horton Fund” or “we”) in furtherance of our correspondence over the past couple months regarding CPS Technologies Corp. (“CPS” or the “Company”). As you know, and included in our Schedule 13D filing with the SEC this morning, investment funds managed by the Horton Fund currently own 661,800 shares (approximately 5% of the common shares outstanding) in CPS.

Over the past few months we have made every effort to collaboratively discuss our proposals for the Company and offer suggestions about how we believe the Company can correct course and begin generating shareholder value. We believe it is unfortunate that the Company has refused to engage in any further dialogue with Horton and that the Board and management are so entrenched they are unwilling to engage constructively with one of the Company’s largest independent shareholders. Rather, it seems that CPS is prepared to spend a significant amount of the shareholders’ money (our estimates for your legal and proxy solicitation bills are hundreds of thousands of dollars) fighting what, we believe, are more than reasonable requests given the Company’s historical performance.

We, nonetheless, were pleased to hear that our prior communications may have accelerated an internal process at the Company to evaluate the composition, performance and needs of the Board of Directors to determine whether the addition, and/or replacement, of Directors is necessary. Given that:

• The average Board tenure is over 15 years,

• No chairman or lead independent director exists,

• There is no separate Governance committee, and

• Management bonuses and equity grants are not specified to the shareholders,

we are confident that the Company must eventually recognize the need for new Board members to provide a fresh perspective, help the company grow its business, improve shareholder returns and implement modern day governance standards.

In an effort to help facilitate the Company’s process, The Horton Fund developed a list of strong, qualified candidates (summaries are included herein) who would be willing to serve on the Board, and, consequently, submitted our Nomination Notice on March 3^rd for the Company’s consideration. During the subsequent three weeks we received no feedback from you regarding our candidates and we were not aware of any outreach made by you to any of our candidates. Our hope for rational dialogue ended last week with your denial of all our candidates without a single interview, and your settlement proposal to nominate one new member at an undefined time in the future without our input in exchange for a two year “standstill”. As you know, we could never agree to such unreasonable terms, but you indicated no interest in any further negotiation.

On March 27, 2017, you filed a preliminary proxy statement with the SEC. We reviewed your filing and were disheartened to learn that the Board believes it is doing a fine job and there will be no member changes at this time. While we believe your preliminary proxy contains factual inaccuracies and potential breaches of the securities laws by the Company, we are incredulous that you have been unable to identify anyone (including any of our candidates) who possesses experience that would fill gaps in the incumbent Board’s composition, and, therefore, we are skeptical that a genuine “process” was conducted at all.

Included in our nomination letter was also a proposal to amend the Company’s Bylaws to establish a majority vote standard in uncontested director elections. This proposal better aligns the Company’s corporate governance policies with that of 2017 ISS proxy voting guidelines. We were pleased to see that on March 24, 2017, the Company adopted this provision and amended its Bylaws to incorporate the standard practice of majority voting. While this action does show some willingness to change, it, frankly, is long overdue and comes across as more reactive to an outside shareholder’s suggestion than any motivated self-improvement initiative by the Board.

In addition, the fact that the Board is so entrenched that it is prepared to spend a significant amount of the shareholder funds to engage in a proxy battle instead of reasonable settlement discussions is just another example of the Company’s poor capital management, and emblematic of its disregard for outside shareholders. While we have been the primary voice on these issues, since we went public with our concerns in December we have heard from numerous significant shareholders holding in aggregate approximately 20% of the outstanding shares that are supportive of our efforts. We are not a “lone wolf” in our positions – the outside shareholder base is frustrated and not supportive of the status quo.

However, we try to be good stewards of capital for our shareholders (our LPs), and recognizing the concentration of ownership within the Board, Horton is withdrawing our formal nomination of Directors (see attached) in order to avoid the immediate destruction of significant shareholder value (both CPS’s and Horton’s). We expect that since the corporate governance proposal described above has been adopted by the Board and the By-laws have been amended, majority voting would be the standard used in all future uncontested director elections, including at the upcoming shareholder meeting.

However, we are not giving up on trying to help the Company reach its potential. Evidencing our commitment to enacting change for the benefit of all shareholders, we have increased our position in the Company and filed a Schedule 13D with the SEC. Included in the 13D are Horton’s December 16 Letter, the March 3 Letter, Nomination Notice, Nomination Withdrawal Notice, and a copy of this letter and attachment.

As always, we remain hopeful about the long-term prospects for CPS Technologies and expect the Company will eventually decide to run the business much more like a public company than a private one, and demonstrate that it is putting the interests of all the shareholders first. We conclude by reemphasizing our belief that adding fresh talent to the Board will help further this goal.

Please do not hesitate to reach out.

Sincerely,

Joe Manko Jr.
