The Company and the Investor Group are each herein referred to as a “party” and collectively, the “parties.”

WHEREAS, as of the Effective Date, the Investor Group collectively beneficially owns an aggregate of 2,735,112 ordinary shares, par value NIS 0.10 per share of the Company (“Ordinary Shares”); and

WHEREAS, the Company and the Investor Group have determined to come to an agreement with respect to the composition of the Company’s Board of Directors (the “Board”) and certain other matters, as provided in this Agreement.

NOW, THEREFORE, in consideration of the foregoing premises and the mutual covenants and agreements contained herein, and for other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the parties, intending to be legally bound hereby, agree as follows:

1.Board Composition and Related Matters.

(a)Raffi Kesten has indicated his willingness to serve as a member of the Board, to replace Miron (Ronnie) Kenneth, a Class II member of the Board. Mr. Kesten has provided the Company, and shall in the future provide the Company as required, with (i) a completed director questionnaire in the form provided to all directors and (ii) information and certifications required of all directors pursuant to the Israeli Companies Law, 5759-1999 (as amended from time to time, the “Companies Law”), the Company’s Articles of Association (as amended from time to time, the “Articles of Association”), and the Company’s committee charters, corporate governance guidelines and similar governance documents, in each case, that are publicly disclosed (collectively with the Companies Law and the Articles of Association, the “Governance Documents”).

(b)Based on the information provided pursuant to Section ‎‎1(a), the Board has resolved, subject to the execution of this Agreement, to appoint Raffi Kesten (as appointed, and including any Replacement Designee pursuant to Section ‎1(e), the “Agreed Nominee”), as a director of the Company, effective immediately upon the execution of this Agreement, to fill the vacancy on the Board created by Mr. Kenneth’s departure from the Board, until the next Annual General Meeting of Shareholders (the “2022 Annual Meeting”).

(c)The Board shall (i) nominate the Agreed Nominee for election to the Board at the 2022 Annual Meeting as a director in “Class II,” to serve until the Company’s 2023 Annual General Meeting of Shareholders (the “2023 Annual Meeting”), (ii) recommend to the shareholders of the Company the election of the Agreed Nominee to the Board at the 2022 Annual Meeting, and (iii) solicit proxies in favor of the election of the Agreed Nominee to the Board at the 2022 Annual Meeting in the same manner as for all other nominees of the Board. The Board shall also (i) nominate the Agreed Nominee for election to the Board at the 2023 Annual Meeting as a member of the class of directors having a term expiring at the 2026 Annual General Meeting of Shareholders, (ii) recommend to the shareholders of the Company the election of the Agreed Nominee to the Board at the 2023 Annual Meeting, and (iii) solicit proxies in favor of the election of the Agreed Nominee to the Board at the 2023 Annual Meeting in the same manner as for all other nominees of the Board.

(d)The Company agrees and acknowledges that Mr. Kesten shall have the same rights and benefits, including with respect to insurance, indemnification, compensation and fees, as are applicable to all non-management directors of the Company. The parties agree that there shall be no contracts, plans or arrangements, written or otherwise, in effect during the term of this Agreement, between either party and the Agreed Nominee providing for any compensation, reimbursement of expenses or indemnification of the Agreed Nominee in connection with or related to the Agreed Nominee’s service on the Board except, in the case of the Company, for such contracts, plans or arrangements as the Company has entered into with other directors.

(e)Until the Termination Date and as long as the Investor Group’s collective Net Long Position exceeds 5.5% of the then outstanding Ordinary Shares (the “Ownership Minimum”), in the event that the Agreed Nominee is unable or unwilling to serve as a director, resigns as a director, is removed as a director or ceases to be a director for any other reason before the Termination Date, the Company and the Investor Group will cooperate in good faith to promptly identify and agree upon a Qualified Candidate to serve as a replacement director (as appointed, the “Replacement Designee”) by the date that is no later than sixty (60) days after the departure of the Agreed Nominee. To the extent the Company and the Investor Group cannot agree on the Replacement Designee candidate, the parties shall continue to follow the procedures of this Section 1(e) until a candidate mutually agreed upon by the parties is appointed to the Board as the Replacement Designee.

(f)Each party acknowledges and agrees that the rights of the Investor Group and the obligations of the Company pursuant to this Section 1 shall terminate immediately upon the Termination Date.

(g)Immediately following the execution of this Agreement, the Board and all applicable committees of the Board shall take all necessary actions to appoint the Agreed Nominee to the Compensation and Nominating Committee of the Board. Without limiting the foregoing, the Board shall give the Agreed Nominee the same due consideration for membership to any committee of the Board as any other director, including any sub-committee or new committee of the Board formed during the term of this Agreement.

2.Voting Commitment. Until the Termination Date, the Investor Group shall, and shall cause its Representatives to, appear in person or by proxy at each Shareholder Meeting and to vote all Ordinary Shares beneficially owned by it and over which it has voting power in accordance with the Board’s recommendations as such recommendations of the Board are set forth in the applicable proxy statement in respect thereof with respect to (a) the election, removal and/or replacement of directors, (b) compensation matters, and (c) any other proposal submitted to the shareholders, other than proposals with respect to an Extraordinary Transaction, in each case as such recommendation of the Board is set forth in the applicable proxy statement in respect thereof; provided, however, that in the event that Institutional Shareholder Services Inc. (“ISS”) or Glass Lewis & Co., LLC (“Glass Lewis”) recommends otherwise with respect to any proposal presented at any Shareholder Meeting (other than (i) proposals relating to the election, removal and/or replacement of directors, (ii) the approval of the Company’s compensation policy adopted pursuant to the Companies Law, and (iii) the appointment/reappointment/removal of the Company’s independent auditor and the authorization to determine their annual compensation), the Investor Group shall be permitted to vote in accordance with the ISS or Glass Lewis recommendation.

3.Participation Right.

(a)Until the Termination Date and as long as the Investor Group’s collective Net Long Position exceeds 4% of the then outstanding Ordinary Shares, if the Company proposes to engage in a Financing, the Company shall provide the Investor Group with a reasonable opportunity to evaluate and share its views with the Board regarding any such Financing and the Company shall consider in good faith any views expressed by the Investor Group in determining whether to proceed with any such Financing.

(b)If the Company determines to proceed with such Financing, the Company shall give written notice (the “Offer Notice”) to the Investor Group, stating (x) its bona fide intention to pursue the Financing, and (y) the general structure of the proposed Financing in sufficient detail so as to permit the Investor Group to provide the detailed terms and conditions upon which the Investor Group would be willing to extend such Financing (the “Investor Group Proposal”). The Investor Group shall provide its response to the Offer Notice within 10 business days of receipt of the Offer Notice. The Company may effect a Financing with a party other than the Investor Group (a) within 90 days of receipt of the Investor Group Proposal on terms that are more favorable than the Investor Group Proposal (“Third Party Proposal”), or (b) if the Investor Group does not provide the Investor Group Proposal within 10 business days of receipt of the Offer Notice; provided, however, that if the Company receives a Third Party Proposal, it shall notify the Investor Group within two (2) business days of receiving such Third Party Proposal and offer the Investor Group an opportunity to instead participate in a Financing on similar terms as such Third Party Proposal.

Press Release

Allot Appoints Raffi Kesten to Board of Directors

Announces Cooperation Agreement with Outerbridge and QVT

HOD HASHARON, Israel, May 12, 2022 -- Allot Ltd. (NASDAQ: ALLT) (TASE: ALLT), a leading global provider of innovative network intelligence and security-as-a-service (SECaaS) solutions for communication service providers (CSPs) and enterprises, today announced that it has appointed Raffi Kesten to its Board of Directors as an independent director. The Company also announced that it has entered into a Cooperation Agreement with Outerbridge Capital Management, LLC (“Outerbridge Capital”), QVT Financial LP, and certain of their affiliates (collectively, “Outerbridge”), which collectively own approximately 7.5% of the Company’s outstanding shares.

Raffi Kesten brings to Allot over 30 years of senior executive business and management experience in the high-tech and cybersecurity industry. Raffi served as the General Manager and COO of NDS, a pay TV media and security company. Following the acquisition of NDS by Cisco, Raffi served as VP of the Service Provider Security and Video Division of Cisco. He later joined JVP, one of Israel’s leading venture capital firms, where he led JVP’s investments in technology startups and served on several Boards, including CyberArk (CYBR). Most recently, Raffi served as Chief Revenue Officer of RadWare (RDWR), a leading provider of cybersecurity and application delivery solutions.

Mr. Kesten will be replacing Ronnie Kenneth, who is leaving the Board (after serving since October 2014) in order to dedicate more time to his new impact fund that he recently established. Mr. Kesten will also be replacing Mr. Kenneth as a member of the Compensation and Nominating Committee, and Mr. Nadav Zohar, a serving Director of the Company, will be replacing Mr. Kenneth as a member of the Audit Committee.

“As a long-term and engaged shareholder, we are pleased to reach this agreement with Allot,” said Rory Wallace, Chief Investment Officer of Outerbridge Capital. “With its market-leading products for network management, DDoS mitigation, and security-as-a-service (SECaaS), Allot can deliver compelling value to service providers as they seek to grow revenues, reduce churn, and protect their networks and end customers from cyberattacks. We believe that Allot’s focus on growing its cybersecurity business is strategically sound, and are pleased to have helped Allot identify a director with impressive and relevant experience to support this growth. Outerbridge intends to continue working constructively with Allot to enhance shareholder value.”

“We are very pleased to welcome Raffi to our Board,” said Yigal Jacoby, Allot’s Chairman of the Board. “Raffi is a veteran who brings significant cyber experience along with business acumen. He is an excellent choice to join our Board. I’d also like to take the opportunity to thank Ronnie Kenneth for his dedicated service and major contribution to Allot over the years with his telecommunications and operational experience.”

Pursuant to the Cooperation Agreement between Allot and Outerbridge, Allot has agreed to nominate Mr. Kesten as a Class II director at the 2022 annual shareholder meeting and then again for a three-year term at the 2023 annual shareholder meeting. Outerbridge has agreed to vote, among other things, in favor of Allot’s board nominees and has agreed to customary standstill provisions until one day after the 2023 annual shareholder meeting, provided that Outerbridge shall be permitted to acquire additional shares to enable total ownership of up to 15% percent of Allot’s outstanding shares during the standstill period. Outerbridge will also have the right to review and participate in financings, if any, from shareholders of Allot at the time of the financing subject to certain exceptions.
