   3
     SEVENTH: Directors of the Corporation need not be elected by written 
ballot unless the bylaws of the Corporation otherwise provide.

     EIGHTH: The directors of the Corporation shall have the power to adopt, 
amend, and repeal the bylaws of the Corporation.

     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, her, or their votes are counted for such purpose, if: (i) the 
material facts as to his or her 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 transaction by the affirmative votes of a majority of the 
disinterested directors, even though the disinterested directors be less than a 
quorum; or (ii) the material facts as to his or her relationship or interest 
and as to the contract or transaction are disclosed or are known to the 
stockholders entitled to vote thereon, and the contract or transaction is 
specifically approved in good faith by vote of the stockholders; or (iii) the 
contract or transaction is fair as to the Corporation as of the time it is 
authorized, approved, or ratified by the board of directors, a committee 
thereof, or the stockholders. Common or interested directors may be 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 
threatened to be made a party to a proceeding (as hereinafter defined) by 
reason of the fact that he or she (i) is or was a director or officer of the 
Corporation or (ii) while a director or officer of the Corporation, is or was 
serving at the 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 as such shall run to the benefit of any director or officer who is elected 
and accepts the position of director or officer of the Corporation or elects to 
continue to serve as a director or officer of the Corporation while this 
Article Tenth is in effect. Any repeal or amendment of this Article Tenth shall 
be prospective only and shall not limit the


                                       2
   4
rights of any such director or officer or the obligations of the Corporation 
with respect to any claim arising from or related to the services of such 
director or officer in any of the foregoing capacities prior to any such 
repeal or amendment to this Article Tenth. Such right 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 sixty (60) 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 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 or her 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: A director of the Corporation shall not 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 

                                       3
   5
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. Any repeal or amendment of 
this Article Eleventh by the stockholders of the Corporation shall be 
prospective only, and shall not adversely affect any limitation on the personal 
liability of a director of the Corporation arising from an act or omission 
occurring prior to the time of such repeal or amendment. In addition to the 
circumstances in which a director of the Corporation is not personally liable 
as set forth in the foregoing provisions of this Article Eleventh, a director 
shall not be liable to the Corporation or its stockholders to such further 
extent as permitted by any law hereafter enacted, including without limitation 
any subsequent amendment to the Delaware General Corporation Law.

     TWELFTH: The Corporation expressly elects not to be governed by Section 
203 of the General Corporation Law of Delaware.

     I, the undersigned, for the purpose of forming the Corporation under the 
laws of the State of Delaware, do make, file and record this Certificate of 
Incorporation and do certify that this is my act and deed and that the facts 
stated herein are true and, accordingly, I do hereunto set my hand on this 20th 
day of September, 1996.
