Attn:  Ms. Anna Surtevall

            Telefonaktiebalaget LM Ericsson (publ) - Direct Registration System
            for ADSs evidenced by Ordinary Shares

Ladies and Gentlemen:

      Reference is made to the Amended and Restated Deposit Agreement, dated as
of September 26, 1995, as amended by Amendment No. 1, dated as of February 10,
1997 and as further amended by Amendment No. 2, dated as of October 23, 2002,
(the "Deposit Agreement"), by and among Telefonaktiebolaget LM Ericsson (publ)
(the "Company"), Citibank, N.A., as Depositary (the "Depositary"), and all
Holders and Beneficial Owners from time to time of American Depositary Receipts
("ADRs") evidencing American Depositary Shares ("ADSs") issued thereunder, each
ADS representing ten (10) B Shares (the "Shares") of the Company. Capitalized
terms used herein without definition shall have the meaning assigned thereto in
the Deposit Agreement.

      The purpose of this letter agreement is to supplement the Deposit
Agreement to enable the establishment by the Depositary of a "direct
registration system" (the "DR System") for ADSs and the issuance by the
Depositary of "uncertificated ADSs" as part of the DR System. In order to enable
such issuance of "uncertificated ADSs", the Company and the Depositary agree as
follows:

      1. Notwithstanding any provision of the Deposit Agreement, the Depositary
may, at any time and from time to time, issue ADSs that are not evidenced by
ADRs (such ADSs, the "Uncertificated ADSs", and the ADSs evidenced by ADRs, the
"Certificated ADSs");

      2. Uncertificated ADSs shall not be represented by any instrument(s) but
shall be evidenced only by the registration of "uncertificated securities" on
the books and records of the Depositary maintained for such purpose. Any
reference to Holders of ADR(s) or ADS(s) in the Deposit Agreement shall, in the
context of the Uncertificated ADSs, refer to the person(s) in whose name the
Uncertificated ADSs are registered on the books of the Depositary maintained for
such purpose;

      3. Holders of Uncertificated ADSs that are not subject to any registered
pledges, liens, restrictions or adverse claims, of which the Depositary has
written notice at such time, shall at all times have the right to exchange the
Uncertificated ADSs (or any portion thereof) for Certificated ADSs of the same
type and class, subject in each case to applicable laws and any rules the
Depositary may establish in respect of the Uncertificated ADSs;


                                       1
<PAGE>

      4. Holders of Certificated ADSs shall, so long as the Depositary maintains
the DR System for the ADSs, have the right to exchange the Certificated ADSs (or
any portion thereof) for Uncertificated ADSs upon (i) the due surrender of the
Certificated ADSs to the Depositary for such purpose, and (ii) the presentation
of a written request to such effect to the Depositary, subject in each case to
(a) all liens and restrictions noted on the ADR evidencing the Certificated
ADS(s) and all adverse claims of which the Depositary then has written notice,
(b) the terms of the Deposit Agreement (as supplemented by this letter
agreement) and the rules that the Depositary may establish from time to time for
such purposes thereunder; and (c) applicable law.

      5. Uncertificated ADSs shall in all material respects be identical to
Certificated ADSs of the same type and class, except that (i) no ADR(s) shall
be, nor shall need to be, issued to evidence Uncertificated ADSs, (ii)
Uncertificated ADSs shall, subject to the terms of the Deposit Agreement (as
supplemented by this letter agreement), be transferable upon the same terms and
conditions as uncertificated securities under New York law, (iii) each Holder's
ownership of Uncertificated ADSs shall be recorded on the books and records of
the Depositary maintained for such purpose and evidence of such Holder's
ownership shall be reflected in periodic statements provided by the Depositary
to each such Holder in accordance with applicable law, (iv) the Depositary may
from time to time, upon notice to the Holders of Uncertificated ADSs affected
thereby, establish rules and amend or supplement existing rules, as may be
deemed reasonably necessary to maintain the DR System and for the issuance of
Uncertificated ADSs on behalf of Holders, provided that such rules do not
conflict with the terms of the Deposit Agreement (as supplemented by this letter
agreement) and applicable law, (v) the Holder of Uncertificated ADSs shall not
be entitled to any benefits under the Deposit Agreement (as supplemented by this
letter agreement) and such Holder's Uncertificated ADSs shall not be valid or
enforceable for any purpose against the Depositary or the Company unless such
Holder is registered on the books and records of the Depositary maintained for
such purpose, (vi) the Depositary may, in connection with any deposit of Shares
resulting in the issuance of Uncertificated ADSs and with any transfer, pledge,
release and cancellation of Uncertiflcated ADSs, require the prior receipt of
such documentation as the Depositary may reasonably request, and (vii) upon
termination of the Deposit Agreement (as supplemented by this letter agreement),
the Depositary shall not require Holders of Uncertificated ADSs to affirmatively
instruct the Depositary before remitting proceeds from the sale of the Deposited
Securities represented by such Holders' Uncertificated ADSs under the terms of
Section 6.02 of the Deposit Agreement;

      6. When issuing ADSs under the terms of the Deposit Agreement, including,
without limitation, issuances pursuant to Sections 4.03 and 4.04 thereof, the
Depositary may in its discretion determine to issue Uncertificated ADSs rather
than Certificated ADSs, unless otherwise specifically instructed in writing by
the applicable Holder to issue Certificated ADSs;

      7. Holders of Uncertificated ADSs may request the sale of ADSs through the
Depositary, subject to the terms and conditions generally applicable to the sale
of ADSs through the Depositary. A copy of the terms and conditions as in effect
on the date hereof is attached hereto as Exhibit A provided that for LM
Ericsson's holders, the service fee will be $10.00 not the $15.00 as stated in
the brochure. Holders of Uncertificated ADSs requesting the sale of all or a
portion of such Uncertificated ADSs will be charged fees for the processing of
such sale (currently consisting of a service fee of $10.00, plus a processing
fee of $0.12 per Uncertificated ADS sold). Fees may be changed at any time and
will be deducted from the proceeds of the sale of Uncertificated ADSs;


                                       2

      8. All provisions and conditions of the Deposit Agreement shall apply to
Uncertificated ADSs to the same extent as to Certificated ADSs, except as
contemplated herein. The Depositary is authorized and directed to take any and
all actions, and establish any and all procedures, deemed reasonably necessary
to give effect to the terms hereof. Any references in the Deposit Agreement or
any ADR(s) to the terms "American Depositary Share(s)" or "ADS(s)"' shall,
unless the context otherwise requires, include Certificated ADS(s) and
Uncertificated ADS(s), individually or collectively, as the context may require;

      9. Except as set forth herein and except as required by applicable law,
the Uncertificated ADSs shall be treated as ADSs issued and outstanding under
the terms of the Deposit Agreement (as supplemented by this letter agreement).
In the event that, in determining the rights and obligations of parties to the
Deposit Agreement (as supplemented by this letter agreement) with respect to any
Uncertificated ADSs, any conflict arises between (a) the terms of the Deposit
Agreement and (b) the terms hereof, the terms and conditions set forth herein
shall be controlling and shall govern the rights and obligations of the parties
to the Deposit Agreement pertaining to the Uncertificated ADSs; and

      10. This letter agreement shall be interpreted under, and all the rights
and obligations hereunder shall be governed by, the laws of the State of New

hereof supplement the Deposit Agreement, and do not prejudice any substantial
existing rights of Holders of ADSs and, as a result, notice may but does not
need to be given of the terms hereof to Holders of ADSs, and (ii) the Company
and the Depositary shall make reference to the terms hereof in, or attach an
executed copy hereof to, the next Registration Statement on Form F-6 filing made

                               DIRECT REGISTRATION

                     THE NEW STANDARD IN AMERICAN DEPOSITARY
                             RECEIPT (ADR) OWNERSHIP

The Direct Registration System (DRS) is a service within the securities industry
that allows your American Depositary Shares (ADSs) representing shares of a
designated company to be held in your name and tracked electronically. You
retain full ownership of your ADSs, without having to hold a certificate (ADR).
Similar to a safekeeping account, you will have an account number and receive
statements that detail your account activity and your ADS balance. This
paperless form of American Depositary Share ownership is commonly referred to as
"book-entry" because your ADSs are accounted for on the books or records of the
Depositary for ADSs. Citibank is the Depositary responsible for your ADSs.

ADSs held in book-entry have all the traditional rights and privileges as ADSs
held in certificate (ADR) form. You will receive all corporate communications,
dividends, annual reports and proxy materials directly from the Depositary.
Plus, by keeping your ADSs in book-entry, you don't have to worry about
protecting your certificates from loss, theft, or destruction. Book-entry
ownership also allows for convenient electronic ADS transactions, such as
ownership transfers, sales, and moving ADSs to or from a broker.

Since being introduced in 1996, book-entry ownership through the DRS has become
the industry standard. It is aligned with the strategic direction of the U.S.
securities industry and has been approved by the Securities and Exchange
Commission and the stock exchanges. Book-entry ownership provides for more
streamlined processing within the securities industry, and reduces the overall
cost. Not all publicly traded ADSs are currently eligible for Direct
Registration.

Yes, you can convert your ADSs held in certificate (ADR) form into book-entry
ADSs by mailing your certificates to Citibank together with a letter of

      $100,000. This limitation is set to protect your account against
      unauthorized sales. It you wish to sell your ADSs that have an anticipated
      market value of more than $100,000, you are expected to submit your
      request in written form. In addition, any sale request within thirty (30)
      days of an address change to your account is expected to be submitted in
      written form. Citibank may, for any reason at its sole discretion and at
      any time, refuse to execute a transaction request submitted by telephone
      and in its place require written submission of such request.

4.    In making a request to sell by telephone, you agree to the terms and
      conditions of the Direct Registration System (DRS) and wee that the
      authorization to sell constitutes an authorization to transfer the ADSs as
      necessary to complete the sale, including transferring ADSs to a nominee
      account of Citibank and to Citibank's broker. By making a request to sell
      by telephone, you further agree that your phone call request constitutes
      an effective and binding instruction on which Citibank may rely.

      applicable brokerage commissions Citibank is required to pay. Sales
      requests received by 1:00 p.m., Eastern Time, on any trading day will be
      treated as received on that day. Sales requests received after 1.00 p.m.,

      requests received on a non-trading day will be deemed to have been
      received on the next trading day.

6.    To maximize cost savings, Citibank will make every effort to sell orders
      in round lot transactions. For this purpose, it may combine one selling
      shareholder's order with those of others. Citibank's broker may be
      required by market conditions to execute more than one transaction in
      filling a given aggregate order for Citibank, and those trades may occur
      at different prices. In every case, the price to each selling ADS holder
      will be the weighted average sales price, net of Citibank service and
      processing fees, obtained by Citibank's broker for each aggregate order
      placed by Citibank.

      traded, in the over-the-counter market, or by negotiated transactions,
      subject to such terms with respect to price, delivery, etc., as Citibank
      may agree. ADS holders may not direct the time or price at which ADSs may

      to be made.

      required to pay. The fees will be deducted from the proceeds of the sale.

      sale should inquire about the applicable fees before requesting a sale.

      at which ADSs are sold for your account. Citibank will have no
      responsibility for the market value of ADSs in your book-entry account,

      control. Citibank shall not be liable for any loss or damage resulting

      electrical or communications system breakdowns, or acts of civil or
      military authority. You agree to indemnify and hold harmless Citibank and
