          value per share."




               FURTHER RESOLVED, that the foregoing proposed amendment be
          submitted to the stockholders of the Corporation for their
          consideration and approval at the 2000 annual meeting of stockholders
          of the Corporation.

               FURTHER RESOLVED, that upon approval of the foregoing proposed
          amendment by the stockholders of the Corporation, the proper officers
          of the Corporation are authorized and directed to execute and
          acknowledge, to file in the office of the Secretary of State of
          Delaware, and to cause to be recorded, in the manner provided by law,
          a Certificate of Amendment to the Restated Certificate of
          Incorporation with respect to the foregoing amendment.

               FURTHER RESOLVED, that the officers of the Corporation are hereby
          authorized and directed to execute and deliver all such certificates,
          agreements, statements, documents and other instruments, and to

          may deem necessary or advisable in order to carry out the purposes and
          intent of these resolutions.

     (3)  Thereafter, pursuant to such resolutions of its Board of Directors,
the stockholders of the Corporation, at a meeting held on April 18, 2000,
adopted the proposed amendment by voting the number of shares required by the
statute in favor of the proposed amendment.

     (4)  The amendment was duly adopted in accordance with the provisions of
Section 242 of the General Corporation Law of the State of Delaware.

     (5)  Accordingly, there has now been given all corporate authorization
necessary to cause the first sentence of Article FOURTH of the Restated
Certificate of Incorporation to provide as follows:

               "The total number of shares of all classes of capital stock which
          the Corporation has the authority to issue is 570,000,000 shares,
          which are divided into two classes as follows:

               10,000,000 shares of Preferred Stock (Preferred Stock) without
          par value, and

               560,000,000 shares of Common Stock (Common Stock), $1.66 2/3 par
          value per share."

     (6)  The Capital of the Corporation will not be reduced under or by reason
of the amendment.
