     EIGHTH: Elections of directors need not be by written ballot unless the
by-laws so provide.

     NINTH: No contract or transaction between the Corporation and one or more
of its directors, officers, or stockholders or between the Corporation and any
person (as used herein "person" means other corporation, partnership,
association, firm, trust, joint venture, political subdivision, or
instrumentality) or other organization in which one or more of its directors,
officers, or stockholders are directors, officers or stockholders, or have a
financial interest, shall be void or voidable solely for this reason, or solely
because the director or officer is present at or participates in the meeting of
the board or committee which authorizes the contract or transaction, or solely
because his or their votes are counted for such purpose, if: (l) the material
facts as to his relationship or interest and as to the contract or transaction
are disclosed or are known to the Board of Directors or the committee, and the
Board of Directors or committee in good faith authorizes the contract or

counted in determining the presence of a quorum at a meeting of the Board of
Directors or of a committee which authorizes the contract or transaction.

     TENTH: The Corporation shall indemnify any person who was, is or is

request of the Corporation as a director, officer, partner, venturer,
proprietor, trustee, employee, agent, or similar functionary of another foreign
or domestic corporation, partnership, joint venture, sole proprietorship, trust,
employee benefit plan, or other enterprise, to the fullest extent permitted
under the Delaware General Corporation Law, as the same exists or may hereafter
be amended. Such right shall be a contract right and shall include the right to
be paid by the Corporation expenses incurred in defending any such proceeding in
advance of its final disposition to the maximum extent permitted under the
Delaware General Corporation Law, as the same exists or may hereafter be
amended. If a claim for indemnification or advancement of expenses hereunder is
not paid in full by the Corporation within 90 days after a written claim has
been received by the corporation, the claimant may at any time thereafter bring
suit against the Corporation to recover the unpaid amount of the claim, and if
successful in whole or in part, the claimant shall also be entitled to be paid
the expenses of prosecuting such claim. It shall be a defense to any such action
that such indemnification or advancement of costs of defense are not permitted
under the Delaware General Corporation Law, but the burden of proving such
defense shall be on the Corporation. Neither the failure of the Corporation
(including its Board of Directors or any committee thereof, independent legal
counsel, or stockholders) to have made its determination prior to the
commencement of such action that indemnification of, or advancement


                                        3



of costs of defense to, the claimant is permissible in the circumstances nor an
actual determination by the corporation (including its Board of Directors or any
committee thereof, independent legal counsel, or stockholders) that such
indemnification or advancement is not permissible shall be a defense to the
action or create a presumption that such indemnification or advancement is not
permissible. In the event of the death of any person having a right of
indemnification under the foregoing provisions, such right shall inure to the
benefit of his heirs, executors, administrators, and personal representatives.
The rights conferred above shall not be exclusive of any other right which any
person may have or hereafter acquire under any statute, by-law, resolution of
stockholders or directors, agreement, or otherwise.

     The Corporation may additionally indemnify any employee or agent of the
Corporation to the fullest extent permitted by law.

     As used herein, the term "proceeding" means any threatened, pending, or
completed action, suit, or proceeding, whether civil, criminal, administrative,
arbitrative, or investigative, any appeal in such an action, suit, or
proceeding, and any inquiry or investigation that could lead to such an action,
suit, or proceeding.

     ELEVENTH: 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, except for liability (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, or (iv) for any transaction from which the director derived an improper
personal benefit.


                                        4



     TWELFTH: The Corporation reserves the right to amend, alter, change or
repeal any provision contained in this certificate of incorporation, in the
manner now or hereafter prescribed by statute, and all rights conferred upon
