     DOES HEREBY CERTIFY:

     FIRST, that on April 27, 1998 the Board of Directors of the Corporation
(the "Board") duly adopted resolutions setting forth a proposed amendment to the

forth the Charter Amendment are as follows:

     CHARTER AMENDMENT

     WHEREAS, the Board of Directors of the Corporation (the "Board of
     Directors") has determined that it is in the best interests of the
     corporation to amend the Corporation's Certificate of Incorporation (the
     "Charter") to eliminate the classification of the Board of Directors with
     respect to directors elected by common stockholders;

     NOW, THEREFORE, BE IT RESOLVED, that an amendment to the Charter (the
     "Charter Amendment") to delete Article SEVENTH (which provides for the
     classification of the Board of Directors with respect to directors elected
     by the common stockholders) and to renumber the remaining Articles of the
     Charter accordingly be and hereby is approved;

     RESOLVED FURTHER, that the Charter Amendment shall be subject to approval
     by the holders of not less than two-thirds of the total voting power of all
     outstanding shares of voting stock of the Corporation, and shall be
     submitted to stockholders for approval; provided, however, that the Board
     of Directors may abandon the Charter Amendment at any time, notwithstanding
     approval of stockholders of such amendment, pursuant to Section 242(c) of
     the DGCL;

     RESOLVED FURTHER, that the officers of the Corporation be, and each of them
     hereby is, authorized and directed on behalf of the Corporation and in its
     name to take any and all acts necessary or advisable to execute,
     acknowledge, file and record such proposed Charter Amendment with the State
     of Delaware and any other public authorities as they shall deem necessary
     or advisable, upon the approval of the Charter Amendment by the
     Corporation's stockholders in accordance with the provisions of the Charter
     and applicable law.

     SECOND, that on June 11, 1998, pursuant to a resolution of the Board and

necessary number of votes as required by statue were given in favor of the
Charter Amendment.

     THIRD, that the Charter Amendment was duly adopted in accordance with the
provisions of Section 242 of the DGCL.

     FOURTH, that the capital of the Company shall not be reduced under or by
reason of the Charter Amendment.
