May 22, 2020

To Brokers, Dealers, Commercial Banks,
Trust Companies and Other Nominees:

We have been appointed by FIMI Israel Opportunity Five and Limited Partnership and FIMI Opportunity V, L.P. (collectively, the “Purchaser”), to act as Information Agent in connection with the Purchaser’s offer to purchase 8,669,029 ordinary shares, par value NIS 1.0 per share (the “Shares”) of Magal Security Systems Ltd. (“Magal”), at a price of $2.95 per Share, net to the seller in cash, less any required withholding taxes and without interest, upon the terms of, and subject to the conditions to, the Offer to Purchase, dated as of the date hereof (the “Offer to Purchase”) and the related Letter of Transmittal (which, as amended from time to time, together constitute the “Offer”) enclosed herewith. The description of the Offer in this letter is only a summary and is qualified by all the terms of, and conditions to, the Offer set forth in the Offer to Purchase and Letter of Transmittal. Terms used herein but not otherwise defined herein have the definitions ascribed thereto in the Offer to Purchase.

Please furnish copies of the enclosed materials to those of your clients for whose accounts you hold Shares registered in your name or in the name of your nominee.

We urge you to contact your clients as promptly as possible. Please note that the initial period of the Offer and withdrawal rights expires at 10:00 a.m., New York time, on June 22, 2020 (the “Initial Completion Date”), unless the Offer is extended.

Your attention is directed to the following:

1. The offer price is $2.95 per Share, net to the seller in cash, less any applicable withholding taxes and without interest.

2. The Purchaser has obtained an approval from the Israeli Tax Authority (the “ITA”) with respect to the Israeli withholding tax rates applicable to shareholders as a result of the purchase of the Shares pursuant to the Offer. The approval provides, among other things, that: (1) tendering shareholders who acquired their Shares after Magal’s initial public offering on Nasdaq Global Select Market (“Nasdaq”) in 1993 and who certify that they are not and at the date of purchase of their Shares were not, Israeli residents (and, in the case of corporations, that no Israeli residents (x) hold 25.0% or more of the means of control such corporations or (y) are the beneficiaries of, or are entitled to, 25.0% or more of the revenues or profits of such corporations, whether directly or indirectly), will not be subject to Israeli withholding tax; and (2) payments to tendering shareholders who acquired their Shares after Magal’s initial public offering on the Nasdaq in 1993 and who hold their Shares through an Israeli broker or Israeli financial institution will be made by the Purchaser without any Israeli withholding at source, and the relevant Israeli broker or Israeli financial institution will withhold Israeli tax, if any, as required by Israeli law. The approval does not address shareholders who are not described in clauses (1) and (2) above, and therefore they will be subject to Israeli withholding tax as required by Israeli law at the applicable rate of the gross proceeds payable to them pursuant to the Offer. Accordingly, if your client determines to tender his or her Shares in the Offer, you should also request instructions as to whether he or she is eligible for (i) an exemption from Israeli withholding tax by completing the enclosed Declaration Form (“Declaration of Status for Israeli Income Tax Purposes”) or (ii) otherwise eligible for an exemption or a more favorable Israeli withholding tax rate and intend to provide a valid tax certificate issued by the Israel Tax Authority.

In general, if your client(s) certifies, by completing the Declaration Form, that it is (1) NOT and at the date of purchase of its Shares was not a “resident of Israel” for purposes of the Israeli Income Tax Ordinance [New Version], 5721-1961 (the “Ordinance”), who acquired their Shares after Magal’s initial public offering on Nasdaq in 1993 or (2) a bank, broker or financial institution resident in Israel that (A) is holding the Shares solely on behalf of its beneficial shareholder(s) (so-called “street name” holders), and (B) is subject to the provisions of the Ordinance and regulations promulgated thereunder relating to the withholding of Israeli tax, including with respect to the cash payment (if any) made by it to its beneficial shareholder(s) with respect to Shares tendered by them and accepted for payment by the Purchaser pursuant to the Offer (an “Eligible Israeli Broker”), your client is eligible for an exemption from Israeli withholding tax. See Section 2 and Section 5 of the Offer to Purchase.

With respect to U.S. backup withholding taxes, see Section 5 of the Offer to Purchase.

The Purchaser, with the assistance of the Depositary and the Depository Trust Company (“DTC”), has established a procedure whereby, if (and only as long as you may tender the Shares on behalf of your clients pursuant to the Offer) you tender Shares in the Offer through DTC, you will be able to classify, electronically, the Shares into the following categories: (1) Shares that are tendered on behalf of your clients who certified to you, by completing the Declaration Form, that they are eligible for an exemption from Israeli withholding tax (“Category One Shares”), and (2) Shares that are tendered on behalf of your clients who are not eligible for such exemption (“Category Two Shares”).

By so classifying, through such DTC system, you will be deemed to certify to the Depositary and to the Purchaser that based on a careful review of the Declaration Forms received by you, the Shares that you classified as Category One Shares, are held by non-Israeli residents and/or Eligible Israeli Broker(s). In addition, in order to confirm your eligibility to make such certification for Category One Shares, you must provide copies of such Declaration Forms as well as any additional information to the Information Agent (via e-mail and utilizing the specialized e-mail address at the end of this notice) that you will be requested to provide in connection therewith. You are reminded that the ITA may have the right to audit the Declaration Forms, and if you refuse, Israeli withholding tax may be imposed. If you fail to meet the deadlines for tendering Shares in the Offer, make untimely classifications or make incorrect classifications, you will be required to claim any withholding tax directly from the ITA. Alternatively, with respect to Category Two Shares, you may receive together with the Letter of Transmittal or Declaration Form certificates of exemption form Israeli withholding or reduced withholding. In such event, you must provide copies of such certificates to the Information Agent with a copy (which shall not constitute notice) to Naschitz, Brandes, Amir & Co., Advocates, our legal counsel in Israel, at its address set forth on the back of the Offer to Purchase. NOTE: A CLIENT OF YOURS THAT IS AN ELIGIBLE ISRAELI BROKER MAY COMPLETE THE DECLARATION FORM IF IT IS HOLDING THE SHARES SOLELY ON BEHALF OF ITS CLIENTS, THE BENEFICIAL SHAREHOLDERS.

3. The Offer is being made for 8,669,029 Shares, representing approximately 37.4% of the issued and outstanding Shares and voting power of Magal, as of the date of the Offer to Purchase.

4. Shareholders may tender their Shares or deliver Notices of Objection until 10:00 a.m., New York time, on the Initial Completion Date (unless the Offer is extended by the Purchaser). The period from the commencement of the Offer until the Initial Completion Date (as may be extended by the Purchaser) is referred to as the Initial Offer Period.

5. Promptly following the Initial Completion Date, the Purchaser will publicly announce whether or not the conditions to the Offer have been satisfied or, subject to applicable law, waived by the Purchaser. As required by Israeli law, if the conditions to the Offer are satisfied or, subject to applicable law, waived by the Purchaser and if, with respect to each Share held by a shareholder:

(i) such shareholder has not yet responded to the Offer,

(ii) such shareholder has notified the Purchaser (through you) of his or her objection to the Offer, or

(iii) such shareholder has tendered such Share (through you) but has withdrawn (through you) such tender prior to the Initial Completion Date,

such shareholder will be afforded an additional four calendar-day period following the Initial Completion Date, during which he or she may tender such Share. This additional period is referred to as the Additional Offer Period. These dates will change if the Purchaser decides to extend the Initial Offer Period. Shareholders may withdraw any previously tendered Shares at any time prior to the completion of the Initial Offer Period, but not during the Additional Offer Period. See “Introduction,” Section 1, Section 3 and Section 4 of the Offer to Purchase.

If, with respect to all or any portion of his or her Shares, a shareholder objects to the Offer during the Initial Offer Period and the conditions to the Offer have been satisfied or, subject to applicable law, waived by the Purchaser, such shareholder may tender such Shares during the Additional Offer Period.

6. Conditions to the Offer include, among other things, that:

(i) prior to 10:00 a.m., New York time, Israel time, on the Initial Completion Date, there shall have been validly tendered and not properly withdrawn at least 1,200,000 Magal Shares (currently representing approximately 5.2% of the issued and outstanding shares and voting power of Magal);

(ii) as required by Israeli law, at 10:00 a.m., New York time, on the Initial Completion Date, the aggregate number of Shares validly tendered and not properly withdrawn (excluding Shares held by the Purchaser or its affiliates – see “Rights of Shareholders Who Do Not Accept the Offer” in the Offer to Purchase) must be greater than the number of Shares represented by Notices of Objection to the Offer; and

(iii) the Israeli Competition Authority shall have approved the purchase of the Shares pursuant to the offer.

The Offer is not conditioned on the availability of financing or the approval of the board of directors of Magal. Please see Section 11 of the Offer to Purchase, which sets forth in full the conditions to the Offer and specifies those conditions to the Offer that are waiveable by the Purchaser.

7. If more than 8,669,029 Shares are validly tendered and not properly withdrawn prior to the expiration of the Additional Offer Period (the “Final Expiration Date”), the Purchaser will purchase 8,669,029 Shares on a pro rata basis from all tendering shareholders. In these circumstances, the number of Shares that the Purchaser will purchase from each tendering shareholder will be based on the total number of Shares validly tendered and not properly withdrawn by all shareholders prior to the Final Expiration Date.

8. If less than 8,669,029 shares are validly tendered, but at least 1,200,000 Shares are validly tendered and not properly withdrawn, Purchaser will purchase Shares from all shareholders who have validly tendered their Shares in the Initial Offer Period and the Additional Offer Period and have not properly withdrawn their Shares before the completion of the Initial Offer Period. Tendering shareholder may only withdraw previously tendered shares prior to the completion of the Initial Offer Period. See Section 1 and Section 4 of the Offer to Purchase.

9. Promptly following the Final Expiration Date, the Purchaser will announce the results of the Offer and the proration factor, if any. If the Purchaser is unable to promptly determine the final proration results, the Purchaser will announce the preliminary results. Shares accepted for payment pursuant to the Offer will be paid promptly following the calculation of the final proration factor.

Explanation of Notice of Objection. Under Israeli law, the shareholders of Magal may respond to the Offer by accepting the Offer and tendering all or any portion of their Shares in accordance with the Offer to Purchase or by notifying the Purchaser of their objection to the Offer by executing and delivering Notices of Objection. Alternatively, they may simply not respond to the Offer and not tender their Shares. It is a condition to the Offer that, at 10:00 a.m., New York time, on the Initial Completion Date, the aggregate number of Shares tendered in the Offer is greater than the number of shares represented by Notices of Objection. In making this calculation, the votes of a holder of a controlling interest in the Purchaser, a holder who has a personal interest in the acceptance of the Offer, a holder of a control block in Magal, or any person acting on its behalf or on behalf of the Purchaser, including their relatives and companies under their control, shall not be taken into account. If this and the other conditions to the Offer have been satisfied or, subject to applicable law, waived by the Purchaser, shareholders will be afforded an additional four calendar days to tender their Shares in the Offer, but Notices of Objection will no longer be accepted. See Section 3 of the Offer to Purchase.

IMPORTANT: IF A SHAREHOLDER SUBMITS A NOTICE OF OBJECTION WITH RESPECT TO HIS OR HER SHARES AND THEREAFTER, DELIVERS TO YOU A LETTER OF TRANSMITTAL BY WHICH HE OR SHE TENDERS THOSE SHARES, PLEASE DISREGARD THE NOTICE OF OBJECTION. SIMILARLY, IF A SHAREHOLDER SUBMITS TO YOU A LETTER OF TRANSMITTAL BY WHICH HE OR SHE TENDERS HIS OR HER SHARES AND THEREAFTER, HE OR SHE DELIVERS TO YOU A NOTICE OF OBJECTION WITH RESPECT TO THOSE SHARES, PLEASE DISREGARD THE LETTER OF TRANSMITTAL. IF A SHAREHOLDER SUBMITS A LETTER OF TRANSMITTAL AND A NOTICE OF OBJECTION CONCURRENTLY WITH RESPECT TO THE SAME SHARES, PLEASE DISREGARD THE NOTICE OF OBJECTION.
