      INSTRUCTIONS AS TO USE OF

      SUBSCRIPTION RIGHTS CERTIFICATES

       

      The following instructions relate to a rights offering (the “Rights Offering”) by Eltek Ltd., an Israeli company
        (“Eltek”), to the holders of its ordinary shares, as described in Eltek’s prospectus dated [___________], 2020 (the “Prospectus”). Each holder of record of ordinary shares at the close of business on [___________], 2020 (the “Record Date”) will
        receive one subscription right (the “Subscription Right”) for every [___________] ordinary shares held by it at the Record Date. Subscription Rights to purchase up to an aggregate of [___________] ordinary shares of Eltek, par value NIS 3.00 per
        share (“Ordinary Shares”), are being distributed in connection with the Rights Offering. Each whole Subscription Right entitles the holder, upon payment of $[__] in cash (the “Subscription Price”), to purchase one Ordinary Shares (the “Subscription
        Right”). In addition, each Subscription Right also carries the right to subscribe at the Subscription Price for additional unsubscribed Ordinary Shares (to the extent available and subject to proration) (the “Over-Subscription Right”). See “The
        Rights Offering” in the Prospectus supplement.

       

      No fractional Subscription Rights or cash in lieu thereof will be issued or paid. Fractional Subscription Rights
        will be rounded down to the nearest whole number, with such adjustments as may be determined at the sole discretion of Eltek which are necessary to ensure that it offers [___] Ordinary Shares in the Rights Offering.

       

      The Subscription Rights will expire at 5:00 p.m., New York City Time (midnight, Israeli time), on [___________],
        2020 (the “Expiration Date”). Any rights not exercised at or before that time will expire worthless without any payment to the holders of those unexercised rights.

       

      The number of Subscription Rights to which you are entitled is printed on the face of your Subscription
        Certificate. You should indicate your wishes with regard to the exercise of your Subscription Rights by completing the appropriate section on the back of your Subscription Certificate and returning the Subscription Certificate to the Subscription
        Agent in the envelope provided.

       

      Your Subscription Certificate must be received by the Subscription Agent on or before the
        Expiration Date. Payment of the Subscription Price of all Subscription Rights exercised, including Subscription Rights pursuant to the Over-Subscription Right, must be received by the Subscription Agent on or before the Expiration Date. You cannot
        revoke your exercise of either your Subscription Right or Over-Subscription Right at any time prior to the expiration of the Rights Offering. In case you hold Subscription Rights through a broker or other nominee, you should verify with your broker
        or nominee by when you must deliver your instruction. See also Section 6 below.

      THE METHOD OF DELIVERY OF THE SUBSCRIPTION CERTIFICATE AND THE PAYMENT OF THE SUBSCRIPTION PRICE TO THE
        SUBSCRIPTION AGENT IS AT YOUR ELECTION AND RISK. IF YOU SEND YOUR SUBSCRIPTION CERTIFICATE AND PAYMENT BY MAIL, THEN THEY SHOULD BE SENT BY REGISTERED MAIL, PROPERLY INSURED, WITH RETURN RECEIPT REQUESTED. A SUFFICIENT NUMBER OF DAYS SHOULD BE
        ALLOWED TO ENSURE DELIVERY TO THE SUBSCRIPTION AGENT PRIOR TO THE EXPIRATION DATE.

       

      2.    Acceptance of Payments. Payments will be deemed to have been received by the Subscription Agent only upon the (i) receipt by the
          Subscription Agent of a bank check payable in U.S. dollars drawn upon a United States of foreign bank or branch; or (ii) receipt by the Subscription Agent of confirmation from its bank that a wire transfer has been received.

       

      3.    Effect of Over - and Underpayments. If you do not indicate the number of Ordinary Shares to be subscribed for on your
          Subscription Certificate or if you indicate a number of Ordinary Shares that does not correspond with the aggregate Subscription Price payment you delivered, you will be deemed to have subscribed for the maximum number of Ordinary Shares that may
          be subscribed for, under both the Subscription Right and the Over-Subscription Right, for the aggregate Subscription Price you delivered. If we do not apply your full Subscription Price payment to your purchase of Ordinary Shares, then we will
          return the excess amount to you by mail, without interest or deduction, as soon as practicable after the Expiration Date. If you subscribe for fewer than all of the Ordinary Shares represented by your Subscription Certificate, then the
          unexercised Subscription Rights will become null and void on the Expiration Date.

      4.    Execution.

       

      	

            	a)	
              Execution By Registered Holder. The signature on the
                Subscription Certificate must correspond with the name of the registered holder exactly as it appears on the face of the Subscription Certificate without any alteration or change whatsoever. Persons who sign the Subscription Certificate in
                a representative or other fiduciary capacity must indicate their capacity when signing and, unless waived by the Subscription Agent in its sole and absolute discretion, must present to the Subscription Agent satisfactory evidence of their
                authority so to act.

            


       

      	

            	b)	
              Execution By Person Other Than Registered Holder. If the
                Subscription Certificate is executed by a person other than the holder named on the face of the Subscription Certificate, proper evidence of authority of the person executing the Subscription Certificate must accompany the same unless the
                Subscription Agent, in its discretion, dispenses with proof of authority.

            


       

      5.    Delivery of Share Certificates, Etc. The issuance of Ordinary Shares purchased in the rights offering will be made not later
          than [___________], 2020 (the “Issuance Date”). The following deliveries and payments to you will be made to the address shown on the face of your Subscription Certificate unless you provide instructions to the contrary on the back of your
          Subscription Certificate:

       

      	

            	a)	
              Share Certificates. The Subscription Agent will mail to each
                validly-exercising Subscription Rights holder who is a record holder certificates representing Ordinary Shares purchased pursuant to the Subscription Right and the Over-Subscription Right.

            


       

       

      	

            	b)	
              Excess Payments. If you exercised your Over-Subscription Right
                and are allocated less than all of the Ordinary Shares for which you wished to over-subscribe, then your excess Subscription Price payment for Ordinary Shares that were not allocated to you will be returned to you by mail, without interest
                or deduction, as soon as practicable after the Issuance Date.

            


       

      6.    To Exercise Subscription Rights through a Bank or Broker. If you are a beneficial owner of our Ordinary Shares and hold them
          through a broker, dealer, bank or other nominee (including a member of The Depository Trust Company (“DTC”), rather than in your own name, you should expect your broker, dealer or other nominee to notify you of this Rights Offering and the
          procedures for exercising or transferring your Subscription Rights. If you wish to exercise your Subscription Rights, you should contact your nominee to exercise your Subscription Rights sufficiently in advance of the expiration date of the
          Rights Offering in order to ensure timely delivery of a Subscription Certificate reflecting your exercise. Your nominee will instruct you as to the proper time and form of payment of the Subscription Price. In that case, the nominee will complete
          the Subscription Certificate on behalf of the record date shareholder and arrange for proper payment.

       

      7.    Procedures for DTC (The Depository Trust Company) Participants. In the case of holders of Subscription Rights that are held of
          record through DTC, exercises of the Subscription Right and the Over-Subscription Right may be effected by instructing DTC to transfer Subscription Rights from the DTC account of such holder to the DTC account of the Subscription Agent, together
          with certification as to the aggregate number of Subscription Rights you are exercising and the number of Ordinary Shares you are subscribing for under your Subscription Right and your Over-Subscription Right, if any, and your Subscription Price
          payment for each Ordinary Share that you subscribed for pursuant to your Subscription Right and your Over-Subscription Right.

       

      8.    Substitute Form W-9. Each Rights holder who elects to exercise the Subscription Rights through the Subscription Agent and who is
          a U.S. person should provide the Subscription Agent with a correct Taxpayer Identification Number (“TIN”) and, where applicable, certification of such Rights holder’s exemption from backup withholding on Substitute Form W-9, which is included in
          this package of subscription materials. Each Rights holder who elects to exercise the Subscription Rights through the Subscription Agent and who is not a U.S. person should provide the Subscription Agent with certification of such Rights holder’s
          foreign status on a Form W-8. Additional copies of the Substitute Form W-9 and copies of Form W-8 may be obtained upon request from the Subscription Agent at the address indicated above. Failure to provide the information on the form may subject
          such holder to federal income tax withholding with respect to any proceeds received by such Rights holder.

      Guidelines for Determining the Proper Identification Number for the Payee (You) to Give the Payer.

       

      Social security numbers have nine digits separated by two hyphens: i.e., 000-00-0000. Employee identification numbers have nine digits
        separated by only one hyphen: i.e., 00-0000000. All “Section” references are to the Internal Revenue Code of 1986, as amended. “IRS” is the Internal Revenue Service.

      Privacy Act Notice

       

      Section 6109 requires you to provide your correct taxpayer identification number to payers, who must report the payments to the IRS.
        The IRS uses the number for identification purposes and may also provide this information to various government agencies for tax enforcement or litigation purposes. Payers must be given the numbers whether or not recipients are required to file tax
        returns. Payers must generally backup withhold on taxable interest, dividend, and certain other payments to a payee who does not furnish a taxpayer identification number to a payer. Certain penalties may also apply.
