                            CERTIFICATE OF AMENDMENT
                                     TO THE
                            ARTICLES OF INCORPORATION
                                       OF
                                TRANSMATION, INC.

        Eric W. McInroy and John A. Misiaszek, being the President and
Secretary, respectively, of Transmation, Inc., an Ohio corporation (the
"Corporation"), do hereby certify that the annual meeting of shareholders of the
Corporation was duly called and held on August 17, 1999, at which meeting a
quorum of shareholders entitled to vote at the meeting was present in person or
by proxy, and that by the affirmative vote of the holders of shares entitled to
exercise not less than two-thirds of the voting power of the Corporation on such
proposal (no greater vote being required by the Articles of Incorporation), the
following resolution was adopted:

                      RESOLVED, that the Articles of Incorporation be amended to
               increase the number of shares of Common Stock which the
               Corporation is authorized to issue from 15,000,000 to 30,000,000.

        Article FOURTH of the Articles of Incorporation is, therefore, hereby
amended to provide in its entirety as follows:

                      "FOURTH: The maximum number of shares which the
               Corporation is authorized to have outstanding is 30,000,000, all
               of which shall be Common Shares with a par value of Fifty Cents
               ($.50) each. No holder of shares of the Corporation of any class
               shall be entitled as such, as a matter of right, to subscribe for
               or purchase shares of the Corporation, or to purchase or
               subscribe for securities convertible into or exchangeable for
               shares of the Corporation, or to which shall be attached or
               appertain any warrants or rights entitling the holder thereof to
               subscribe for or purchase shares of the Corporation, except such
               rights of subscription or purchase, if any, for such
               considerations and upon such terms and conditions as its Board of
               Directors from time to time may determine."
