The Board of Directors

Radcom Ltd.

24 Raoul Wallenberg Street

Tel-Aviv 69719, Israel

Dear Members of the Board:

We are writing on behalf of Value Base Ltd. (including its affiliated entities) and the Zisapel siblings (collectively, the “Shareholders”), who together beneficially own approximately 19.27% of the Ordinary Shares of Radcom Ltd. (“Radcom” or the “Company”).

Our substantial investment in Radcom reflects our firm conviction that the Company possesses a fundamentally sound operating business, an established market position and significant potential to enhance shareholder returns.

Unfortunately, we believe this potential has been chronically under-realized due to a failure by a majority of the Board of Directors to execute value-maximization initiatives and efficiently manage capital reserves. In addition, the structure of the Company’s balance sheet is severely ineffective. Recent changes in the Company’s corporate governance, including the removal of the Chairman of the Board, have raised further concerns regarding the current trajectory of leadership. After review, we have concluded that the Company is materially underperforming and suffers from a persistent stagnation of shareholder value.

This chronic underperformance is not attributable to broader macroeconomic conditions; rather, it stems from governance and strategic deficiencies that fall squarely within the Board’s oversight responsibilities. We believe substantial shareholder value can only be unlocked through decisive action, beginning with the reconstitution of a significant portion of the Board with experienced, independent directors.

Accordingly, pursuant to Section 63(b)(2) of the Companies Law of 1999, Regulation 7A of the Companies Regulations (Relief for Companies whose Shares are listed on a Stock Exchange Outside of Israel), 2000, and Article 39 of the Company's Amended and Restated Articles of Association (the "Articles"), we hereby demand that the Board call, no later than April 6, 2026, a special meeting (the "Special Meeting"), that will be held no later than May 11, 2026. The agenda for this Special Meeting shall include the following items:

(1)

Number of Directors: To amend Article 38 as follows:

“Number of Directors The Board of Directors shall consist of such number of Directors (not less than three (3) nor more than nine seven (97)) as may be determined by Shareholder Resolution of the Company.”

(2)

Amendment to Article 39(c): To amend the first sentence of Article 39(c) of the Articles as follows:

"(c) Directors (other than External Directors) shall be elected at any the Annual General Meeting by the vote of the holders of a majority of the voting power represented at such meeting in person or by proxy and voting on the election of directors, or by the Board of Directors."

(3)

Amending Article 41: To add the following sentence at the end of Article 41 of the Articles:

“Notwithstanding the previous sentence, the directorship of board members who were appointed by the Board of Directors prior to the Special Meeting, shall automatically terminate upon the conclusion of the Special Meeting.”

(4)

Removal of Directors: The removal of the following directors from the Company’s Board of Directors, effective at the conclusion of the Special Meeting:

•

Rami Schwartz

•

Rachel (Heli) Bennun

•

Oren Most

•

Yaron Ravkaie

•

Andre Fuetsch

(5)

Election of New Directors: Subject to the approval of Item 2, the election by shareholders of the following candidates (the "Candidates") to the Company's Board of Directors, effective upon the conclusion of the Special Meeting, for the term set forth in Article 39(C) of the Articles:

•

Liat Aaronson

•

Tomer Jacob

•

Guy Levit

Enclosed are biographical summaries for each Candidate, along with the required director declarations and background questionnaires. We emphasize that these Candidates are highly qualified, independent and unaffiliated with the undersigned Shareholders. We believe this strong slate of directors, working alongside the remaining Board members, will be equipped to steer the Company toward market leadership and long-term value creation.

(6)

Approval of Compensation and Indemnification: The approval of compensation, exemption, indemnification and insurance for the Candidates at levels commensurate with those currently provided to the Company’s existing directors, based on the director compensation scheme approved at the Company's 2024 Annual General Meeting.

We remind the Board that your fiduciary duty is owed to all shareholders, rather than to the entrenchment of the existing Board.

We expect that during the period from the date hereof and until the Special Meeting is held, and the reconstituted board assumes its role, the Company will not enter into any material transactions or take any material actions that will affect its balance sheet, assets, cash reserves, corporate structure, corporate governance or governing documents.

For the avoidance of doubt, it is clarified that, except for the matters set forth in this letter, the undersigned Shareholders have no understandings, coordination or joint commitments regarding the Company’s shares.
