                             INSTRUMENT OF ADOPTION
                                       OF
           THE LINCOLN NON-EMPLOYEE DIRECTORS' RESTRICTED STOCK PLAN

         WHEREAS, The Lincoln Electric Company (the "Company") has previously
adopted The Lincoln Non-Employee Directors' Restricted Stock Plan (the "Plan");

         WHEREAS, pursuant to an Agreement of Merger dated as of May 19, 1998 by
and among Lincoln Electric Merger Co., The Lincoln Electric Company and Lincoln
Electric Holdings, Inc. (the "Agreement"), The Lincoln Electric Company (the
"Company") became a wholly owned subsidiary of Lincoln Electric Holdings, Inc.
("Holdings"), effective as of June 2, 1998; and

         WHEREAS, pursuant to the Agreement, Holdings shall assume the Plan and
all obligations of the Company with respect thereto;

         NOW THEREFORE, Holdings hereby assumes the obligations of the Company
under the Plan and adopts The Lincoln Non-Employee Director's Restricted Stock
Plan as hereinafter set forth:

         1.       On each January 1, each non-employee Director of Holdings
                  ("Director") shall be automatically granted $10,000 worth of
                  Common Shares, without par value, of Holdings ("Holdings
                  Shares") subject to the transfer restrictions and risk of
                  forfeiture hereinafter described ("Restricted Shares").

         2.       The value of Holdings Shares for the purposes hereof shall be
                  equal to the last reported trading price for the Holdings
                  Shares.

         3.       The aggregate number of Holdings Shares that may be awarded as
                  Restricted Shares and released from substantial risk of
                  forfeiture under the Plan shall not exceed 200,000 Holdings
                  Shares, which may be shares of original issuance or treasury
                  share or a combination.

         4.       Restricted Shares held by a Director may not be sold or
                  otherwise disposed of until, and shall be forfeited if such
                  Director ceases to serve as a Director of Holdings before, the
                  restrictions lapse as provided below.

         5.       The restrictions on each award of Restricted Shares shall
                  lapse when the Director has served continuously as a Director
                  of Holdings for a period of three years after the award;
                  provided, however, that the restrictions shall lapse earlier
                  if the Director (i) dies or (ii) completes the term in which
                  the award was received and
   2
                  is not elected to another term by the shareholders, or (iii)
                  in the event of a change in control of Holdings as defined in
                  paragraph 8 hereof.

         6.       Directors shall have all the rights of shareholders with
                  respect to such Restricted Shares, provided that such
                  Restricted Shares, together with any additional shares of
                  Holdings that a Director may receive by virtue of any share
                  dividend, merger, reorganization or other change in capital
                  structure, shall be subject to the restrictions set forth
                  above.

         7.       The automatic awards of Restricted Shares herein provided for
                  may be referred to as "The Lincoln Non-Employee Directors'
                  Restricted Stock Plan" and shall continue, subject to
                  availability of shares, until such automatic awards are
                  discontinued by resolution of the Board of Directors of
                  Holdings.

         8.       A "change in control" shall occur upon the happening of any of
                  the following events:

         (a)      Holdings is merged or consolidated or reorganized into or with
                  another company or other legal person, and as a result of such
                  merger, consolidation or reorganization less than a majority
                  of the combined voting power of the then-outstanding
                  securities of such company or person immediately after such
                  transaction is held in the aggregate by the holders of the
                  then outstanding securities entitled to vote generally in
                  election of the Directors of Holdings ("Voting Stock")
                  immediately prior to such transaction;

         (b)      Holdings sells or otherwise transfers all or substantially all
                  of its assets to any other company or other legal person, and
                  as a result of such sale or transfer less than a majority of
                  the combined voting power of the then-outstanding securities
                  of such company or person immediately after such sale or
                  transfer is held in the aggregate by the holders of Voting
                  Stock of Holdings immediately prior to such sale or transfer;
                  or

         (c)      Any person or group of persons (within the meaning of Section
                  13 or 14 of the Securities Exchange Act of 1934) shall have

                  under said Act) of 30% or more of the outstanding Voting
                  Stock, excluding (i) any person or group of persons who are
                  officers, Directors, or employees of Holdings or any

                  marriage to the descendants

                  similar arrangements for any of the foregoing and any
                  foundations established by any other foregoing and (ii) any
