              Re:   Amendment to Note Agreement

Ladies and Gentlemen:

         Reference is made to that certain Note Agreement dated November 20,
1991 (as amended from time to time, the "Note Agreement") between The Lincoln
Electric Company, an Ohio corporation (the "Company"), and The Prudential
Insurance Company of America ("Prudential"), pursuant to which the Company
issued and sold and Prudential purchased the Company's 8.73% senior note in the
original principal amount of $75,000,000, due November 26, 2003 (the "Note").
Unless otherwise defined herein, capitalized terms used herein shall have the
meanings assigned to such terms in the Note Agreement.

         The Company has advised Prudential that the Company and the Company's
sole shareholder, Lincoln Electric Holdings, Inc. ("Holdings"), intend to
consummate a reorganization of the corporate structure of the Company and its
Subsidiaries (the "Reorganization") substantially on the terms described in the
Proxy Statement/Prospectus of the Company dated April 20, 1998, as in effect on
such date, and in the supplemental materials provided by the Company to
Prudential prior to the Amendment Effective Date (as defined in Section 4
hereof) related thereto (collectively, the "Reorganization Documents").

         Pursuant to the Reorganization, the Company may transfer to Holdings
and/or certain subsidiaries of Holdings (other than Subsidiaries) all of the
capital stock of the subsidiaries listed on Schedule I attached hereto (the
"Disposed Subsidiaries") and all of the assets held by the Disposed
Subsidiaries, whether by asset transfer, merger, consolidation or otherwise,
substantially on the terms set forth in the Reorganization Documents.

         Pursuant to the Company's request, the banks party to the Credit
Agreement are willing to permit the Reorganization upon the terms set forth in
Amendment No. 3 to Credit Agreement attached hereto as Schedule II.

         In order to effect the Reorganization, the Company has requested that
Prudential enter into this agreement. Consequently, pursuant to the request of
the Company and in accordance with the provisions of paragraph 11C of the Note
Agreement, Prudential and the Company agree as follows:

         SECTION 1. Amendment. On the Amendment Effective Date, the Note
Agreement is hereby amended as follows:

         1.1 References to Bank Agreement and Credit Agreement. Paragraph 10B of
the Note Agreement is amended to delete the defined term "Bank Agreement" and
"Credit Agreement" appearing therein and to substitute therefor the following
definition:

                  "Bank Agreement" and "Credit Agreement" shall mean and refer
         to that certain Credit Agreement dated as of December 20, 1995 among
         the Company, the banks listed therein and KeyBank National Association
         (f/k/a Society National Bank), as agent, as amended by Amendments No.1,
         2 and 3 thereto as in effect on the date of the effectiveness of the
         amendment to this Agreement dated November 11, 1998.

         1.2 Consent to Amendment. Prudential hereby expressly consents to the
Amendment No. 3 to Credit Agreement in the form attached as Schedule II hereto.

         1.3 Addendum to Exhibit E. The Note Agreement is hereby amended to add
to Exhibit E attached thereto Amendment No. 3 to the Credit Agreement attached
hereto as Schedule II.

         SECTION 2. Effect of Changes to Credit Agreement. All references herein
to the Credit Agreement and the Company's compliance with the terms thereof as
required under the Note Agreement shall be based upon the Credit Agreement as in
effect on the Amendment Effective Date without giving effect to any other
amendment, waiver or other modification of the Credit Agreement unless the
Company shall have obtained the written consent of the Required Holder(s) to any
such amendment, waiver or modification. No termination of the Credit Agreement
in whole or in part shall affect the continued applicability of the sections of
the Credit Agreement referred to herein.

         SECTION 3. Representations and Warranties. The Company hereby
represents and warrants that this letter is a legally valid and binding
obligation of the Company, enforceable against the Company in accordance with
its terms except as enforcement may be limited by bankruptcy, insolvency,
reorganization, moratorium or similar laws now or hereafter in effect relating
to creditors' rights generally or general principles of equity. The Company
represents and warrants that the Reorganization Documents do not contain any
untrue statement of a material fact or omit to state a material fact necessary
in order to make the statements contained therein not misleading (any interim
financial information is subject to changes resulting from audits and year-end
adjustments).
