                                      VII.

         No director of the Corporation shall be personally liable to the
Corporation or its stockholders for monetary damages for breach of fiduciary
duty as a director, provided, however, that this Article III shall not eliminate
or limit the liability of a director to the extent provided by applicable law
(i) for any breach of the director's duty of loyalty to the Corporation or its
stockholders, (ii) for acts or omissions not in good faith or which involve
intentional misconduct or knowing violation of law, (iii) under Section 174 of
the Delaware General Corporation Law (as in effect and as hereafter amended), or
(iv) for any transaction from which the director derived an improper personal
benefit. If the Delaware General Corporation Law is amended after approval by
the stockholders of this Article VII to authorize corporate action further
eliminating or limiting the personal liability of directors, then the liability
of each director of the Corporation shall be eliminated or limited to the
fullest extent permitted by the Delaware General Corporation Law, as so amended.
Neither the amendment nor repeal of this Article VII, nor the adoption of any
provision of this Certificate of Incorporation inconsistent with this Article
VII, shall eliminate or reduce the effect of this Article VII in respect of any
acts or omissions occurring prior to such amendment, repeal or adoption or any
inconsistent provision.

                                     VIII.

         Election of Directors need not be by written ballot unless the Bylaws
of the Corporation shall so provide.

         IN WITNESS WHEREOF, the undersigned incorporator has executed this
Certificate of Incorporation on this 7th day of December, 1998.
