The Board of Directors recommends that you vote “FOR” the proposal.

Whether or not you plan to attend the General Meeting, it is important that your ordinary shares be represented. Accordingly, holders of ordinary shares (whether registered in their name or in “street name”) will receive voting instruction cards in order to instruct their banks, brokers or other nominees on how to vote, and they are kindly requested to complete, date, sign and mail the voting instruction card in the envelope provided at the earliest convenience so that it will be received no later than the date and time indicated on the form of the voting instruction card.

Such certificate must be approved by a recognized financial institution, as required by the Israeli Companies Regulations (Proof of Ownership of Shares for Voting at General Meeting) of 2000, as amended.

At the close of business on August 31, 2023, the Company had outstanding 11,447,676 ordinary shares, excluding 18,409 ordinary shares held in treasury, each of which is entitled to one vote on each of the matters to be presented at the General Meeting.  

How You Can Vote

Shareholders registered in the Company’s shareholders’ register may vote in the General Meeting in person or vote through the attached form of proxy card, which also serves as their voting card, by completing, dating, signing and mailing the proxy card to the Company’s offices so that it is received by the Company no later than on October 10, 2023, at 06:00 a.m. Israel time.

Such certificate must be approved by a recognized financial institution, as required by the Israeli Companies Regulations (Proof of Ownership of Shares for Voting at General Meeting) of 2000, as amended.

Shareholders who hold their ordinary shares in “street name”, meaning in the name of a bank, broker or other record holder, through Computershare, must either direct the record holder of their ordinary shares how to vote their ordinary shares, or obtain a legal proxy from the record holder to vote at the General Meeting on behalf of the record holder together with a proof of such record holder with respect to the holding of the ordinary shares on the record date. You should follow the directions provided by your broker or nominee regarding how to instruct them to vote your shares.

Certain officers, directors, employees, and agents of the Company, none of whom will receive additional compensation therefor, may solicit proxies by telephone, emails, or other personal contact. The Company will bear the cost for the solicitation of the proxies, including postage, printing, and handling, and will reimburse the reasonable expenses of brokerage firms and others for forwarding material to beneficial owners of ordinary shares.

Note for Shareholders Voting via Proxy Card

Shareholders who vote their shares via proxy card may use the form of proxy and the return envelope enclosed. Shares represented by executed and unrevoked proxies will be voted at the Meeting.

Shareholders may revoke their proxies at any time before the effective exercise thereof by filing with the Company a written notice of revocation or a duly executed proxy card and/or voting instruction card bearing a later date, or by voting their ordinary shares in person at the General Meeting if the shareholders are the record holder of the ordinary shares and can provide evidence of such (i.e., a copy of certificate(s) evidencing their ordinary shares). If a shareholder’s proxy is not received by the Company by Tuesday, October 10, 2023, at 06:00 a.m., Israel time, it shall not be valid at the General Meeting. Notwithstanding the aforesaid, each of the chairman of the General Meeting or the Company’s Secretary may, at his or her discretion, accept proxies after such time if he or she so deems fit.

Multiple Record Holders or Accounts

You may receive more than one set of voting materials, including multiple copies of this document and multiple proxy cards or voting instruction cards. For example, shareholders of record whose ordinary shares are registered in more than one name will receive more than one proxy card. You should complete, sign, date and return each proxy card and voting instruction card you receive. 

Quorum

Two or more shareholders present, personally or by proxy, holding not less than 20% of the outstanding ordinary shares shall constitute a quorum for the General Meeting. If within half an hour from the time appointed for the General Meeting a quorum is not present, the General Meeting shall be adjourned for one week (to the same day, time and place), or at such other day, time and place as shall be prescribed by the Board of Directors in a notification to the shareholders. If a quorum is not present at the adjourned General Meeting within half an hour from the time appointed for such adjourned General Meeting, any number of shareholders present personally or by proxy shall be deemed a quorum and shall be entitled to deliberate and to resolve in respect of the matters for which the General Meeting was convened. Abstentions are counted as holders present for the purpose of determining a quorum.

Vote Required for the Proposal

The approval of the proposal requires the affirmative vote of a majority of the shareholders participating in the voting at the General Meeting in person or by proxy; provided, that (i) such majority vote at the General Meeting shall include a majority of the total votes of shareholders participating in the voting at the General Meeting in person or by proxy who (a) are not controlling shareholders of the Company or (b) do not have a personal interest in the approval of the proposal (votes abstaining shall not be taken into account in counting the above-referenced shareholders’ votes); or (ii) the total number of ordinary shares of the shareholders mentioned in clause (i) above that are voted against such proposal does not exceed two percent (2%) of the total voting rights in the Company.

Under the Israeli Companies Law of 1999 (“Companies Law”), each shareholder that attends the General Meeting in person shall, prior to exercising its voting rights at the General Meeting, advise the Company whether or not that shareholder is a controlling shareholder of the Company and whether or not that shareholder has a personal interest with respect to the approval of the proposal. Each shareholder that delivers a signed proxy to the Company must indicate on the proxy whether or not that shareholder is a controlling shareholder of the Company and whether or not that shareholder has a personal interest with respect to the approval of the proposal. Shareholders who do not so indicate will not be eligible to vote their ordinary shares as to such proposal.

The Companies Law defines a “personal interest” as a personal interest of a person in an act or transaction of a company, including: (i) a personal interest of that person’s relative (i.e., spouse, sibling, parent, grandparent, child, child sibling and parent of such person’s spouse or the spouse of any of the above); or (ii) a personal interest of another entity in which that person or his or her relative (as defined above) holds 5% or more of such entity’s issued shares or voting rights, has the right to appoint a director or the chief executive officer of such entity, or serves as director or chief executive officer of such entity. A personal interest resulting merely from holding a company’s shares will not be deemed a personal interest.

The term “controlling shareholder” shall carry the meaning ascribed to it in the Companies Law and shall mean a person’s ability to direct a company’s business, unless such ability stems only from the service as a director or from includer position in the company, and there is a presumption that a person is controlling a company if such person holds 50% or more of a certain type of means of control in the company. For this purpose, “Means of Control” shall mean any of the below: (i) voting rights in the company’s general meeting or in an equivalent body of another corporation; (ii) the right to appoint the company’s directors or its chief executive officers. The term “controlling shareholder” shall also include a holder of 25% or more of the voting rights in the Company if there is no other holder holding more than 50% of the voting rights in the Company. For the purpose of the term “holding” two or more persons holding voting rights in a company while each of them has a personal interest in the approval of the same transaction brought for the approval of the company shall be deemed as joint holders.

To the extent you would like to submit a position statement with respect to the proposal described in the Proxy Statement pursuant to the Companies Law, you may do so by delivery of appropriate notice to the Company’s offices (Attention: Eran Rotem, Deputy CEO and CFO) located at 4 Oppenheimer St., Weizmann Science Park, Rehovot 7670104, Israel, not later than ten days before the General Meeting date (i.e., Saturday, September 30, 2023).

APPROVAL OF THE REPRICING OF THE EXERCISE PRICE OF CERTAIN OUTSTANDING OPTIONS TO PURCHASE ORDINARY SHARES OF THE COMPANY GRANTED TO THE COMPANY’S DIRECTORS AND ITS CEO.

Following the approval of the Company’s compensation committee (the “Compensation Committee”) and the Board of Directors, and as part of a broader repricing decision applying to employees and officers of the Company, it is proposed that the General Meeting approve the repricing of a total of 583,979 outstanding options, each exercisable into one (1) ordinary share of the Company, previously granted to the Company’s directors and CEO, such that their exercise price shall be U.S. $6.39, which represents the average of the closing price of the Company’s shares during the 30-days preceding the Board of Directors decision on the repricing, and comprised of: (i) 162,713 options and 50,000 options at an exercise price of U.S. $11.06 and U.S. $9.22, respectively, previously granted to Dr. Roger Pomerantz, the Chairman of the Board of Directors; (ii) 23,000 options and 24,000 options at an exercise price of U.S. $15.20 and U.S. $9.22, respectively, previously granted to Hugh Evans, a director of the Company; (iii) 8,000 options and 24,000 options, at an exercise price of U.S. $9.12 and U.S. $9.22, respectively, previously granted to each of Dr. Avraham (Avri) Havron, Dr. Elan Penn, and Mr. Joseph Zarzewsky, directors of the Company; (iv) 47,000 options at an exercise price of U.S. $9.22, previously granted to Lask Alisa, a director of the Company; and (v) 100,000 options and 81,266 options at an exercise price of U.S. $9.22 and U.S. $10.08, respectively, previously granted to Mr. Yehiel Tal, the Company’s director and CEO, (together in this proposal, the “Repricing”).

The aggregate additional annual economic benefit of the Repricing to the directors and CEO under the Black-Scholes formula ranges between U.S. $3,789 and U.S. $39,300 and is in accordance with the Company’s compensation policy.

In its decision, the Compensation Committee and the Board of Directors noted the following considerations:

In light of the above considerations, the Compensation Committee and Board of Directors resolved that Repricing of the exercise price of certain outstanding options to purchase ordinary shares of the Company granted to the Company’s directors and its CEO, as described above, is fair and reasonable, and to the benefit of the Company.

It is proposed that at the General Meeting the following resolution be adopted:

“RESOLVED, that the repricing of the exercise price of certain outstanding options to purchase ordinary shares of the Company granted to the Company’s directors and its CEO, as presented to the shareholders, be and the same hereby is, approved.”

The Board of Directors recommends a vote “FOR” approval of the proposed resolution.
