                                                                         [STAMP]

                     CERTIFICATE OF PRESIDENT AND SECRETARY
                                       OF
                            O-I HOLDING COMPANY, INC.
                               (Ohio Corporation)

                        SHOWING APPROVAL AND ADOPTION OF
                               AGREEMENT OF MERGER

          David G. VanHooser, President, and Thomas L. Young, Secretary, of O-I
Holdings Company, Inc., a corporation organized and existing under the laws of
Ohio, do hereby certify as such officers of said corporation that the Agreement
of Merger to which this certificate is attached after having been signed on
behalf of O-I Holdings Company, Inc., a corporation of the State of Ohio, the
surviving corporation of this merger, was duly adopted pursuant to Title 17,
Section 1701.80 of the Revised Code of Ohio by unanimous written action of the
Board of Directors of said corporation on October 31, 1991, the articles or
regulations of said corporation do not require that the agreement be adopted by
the shareholders or by the holders of a particular class of shares of said
corporation.

          The Agreement of Merger does not conflict with the articles or
regulations of said corporation and there is no change to the articles or
regulations of said corporation nor any action authorized which apart from the
merger would require adoption of the Agreement of Merger by the shareholders or
by the holders of a particular class of shares of said corporation. The merger
does not involve the issuance or transfer by the said surviving corporation to
the shareholders of any of the subsidiaries which are parties to the merger of
such number of shares of the surviving corporation which will entitle the
holders thereof after the consummation of the merger to exercise one-sixth or
more of the voting power of said corporation in the election of directors. There
is no change in the directors of said corporation that would require action by
the shareholders or by the holders of a particular class of said surviving
corporation. That said corporation is the owner of all issued and outstanding
shares of its said subsidiaries which are parties to the merger, all as set out
in Section 5 of the Agreement of Merger, in which section all of said
subsidiaries are identified. That the Agreement of Merger was thereby adopted by
unanimous action of the Board of Directors of said O-I Holdings Company, Inc.,
the surviving corporation, and is the duly adopted agreement and act of said
corporation.

          IN WITNESS WHEREOF David G. VanHooser, President, and Thomas L. Young,
Secretary, have hereunto subscribed their names this 31st day of October, 1991.
