            date which is 5 years from the date of issue of the Director's

Corporation may merger or consolidate with another entity if:

      (i)   the entity surviving such merger or consolidation is a Delaware

            the vote of stockholders as is required by the General Corporation

laws of the State of Delaware, the Board of Directors is expressly authorized
and empowered to make, alter and repeal the By-laws of the Corporation, subject
to the power of the stockholders of the Corporation to alter or repeal any
by-law made by the Board of Directors.

        A director of this Corporation shall not be liable to the Corporation
or its stockholders for monetary damages for breach of fiduciary duty as a
director, except to the extent such exemption from liability or limitation
thereof is not permitted under the General Corporation Law as the same exists
or may hereafter be amended.

        Any repeal or modification of the foregoing paragraph shall not
adversely affect any right or protection of a director of the Corporation
existing hereunder with respect to any act or omission occurring prior to such
repeal or modification.

to amend, alter, change or repeal any provision contained in this Certificate
of Incorporation, and other provisions authorized by the laws of the State of
