     FOURTH:
     ------

     A.       The Corporation is authorized to issue a total of 152,000,000
              shares of stock in two classes designated respectively "Preferred
              Stock" and "Common Stock". The total number of shares of all
              series of Preferred Stock that the Corporation shall have the
              authority to issue is 2,000,000 and the total number of shares of
              Common Stock that the Corporation shall have the authority to
              issue is 150,000,000. All of the authorized shares shall have a
              par value of $0.001.

              The shares of Preferred Stock may be divided into such number of
              series as the Board of Directors may determine. The Board of
              Directors is authorized to determine and alter the rights,
              preferences, privileges and restrictions granted to and imposed
              upon the Preferred Stock or any series thereof with respect to any
              wholly unissued series of Preferred Stock, and to fix the number
              of shares of any such series of Preferred Stock. The Board of
              Directors, within the limits and restrictions stated in any

                                        1



              resolution or resolutions of the Board of Directors originally
              fixing the number of shares constituting any series, may increase
              or decrease (but not below the number of shares of such series
              then outstanding) the number of shares of any series subsequent to
              the issue of shares of that series.

     FIFTH:   The following provisions are inserted for the management of
     -----    the business and the conduct of the affairs of the Corporation,
              and for further definition, limitation and regulation of the
              powers of the Corporation and of its directors and stockholders:

     A.       The business and affairs of the Corporation shall be managed by or
              under the direction of the Board of Directors. In addition to the
              powers and authority expressly conferred upon them by statute or
              by this Certificate of Incorporation or the Bylaws of the
              Corporation, the directors are hereby empowered to exercise all
              such powers and do all such acts and things as may be exercised or
              done by the Corporation.

     B.       The directors of the Corporation need not be elected by written
              ballot unless the Bylaws so provide.

     C.       On and after the closing date of the first sale of the
              Corporation's Common Stock pursuant to a firmly underwritten
              registered public offering (the "IPO"), any action required or
              permitted to be taken by the stockholders of the Corporation must
              be effected at a duly called annual or special meeting of
              stockholders of the Corporation and may not be effected by any
              consent in writing by such stockholders. Prior to such sale,
              unless otherwise provided by law, any action which may otherwise
              be taken at any meeting of the stockholders may be taken without a
              meeting and without prior notice, if a written consent describing
              such actions is signed by the holders of outstanding shares having
              not less than the minimum number of votes which would be necessary
              to authorize or take such action at a meeting at which all shares
              entitled to vote thereon were present and voted.

     D.       Special meetings of stockholders of the Corporation may be called
              only by the Board of Directors pursuant to a resolution adopted by
              a majority of the total number of authorized directors (whether or
              not there exist any vacancies in previously authorized
              directorships at the time any such resolution is presented to the
              Board for adoption).

                                        2



     SIXTH:
     -----

     A.       The number of directors shall initially be set at five (5) and,
              thereafter, shall be fixed from time to time exclusively by the
              Board of Directors pursuant to a resolution adopted by a majority
              of the total number of authorized directors (whether or not there
              exist any vacancies in previously authorized directorships at the
              time any such resolution is presented to the Board for adoption).
              Upon the closing of the IPO, the directors shall be divided into
              three classes with the term of office of the first class (Class I)
              to expire at the first annual meeting of the stockholders
              following the IPO; the term of office of the second class (Class
              II) to expire at the second annual meeting of stockholders held
              following the IPO; the term of office of the third class (Class
              III) to expire at the third annual meeting of stockholders; and
              thereafter for each such term to expire at each third succeeding
              annual meeting of stockholders after such election. Subject to the
              rights of the holders of any series of Preferred Stock then
              outstanding, a vacancy resulting from the removal of a director by
              the stockholders as provided in Section 3 below may be filled at a
              special meeting of the stockholders held for that purpose. All
              directors shall hold office until the expiration of the term for
              which elected, and until their respective successors are elected,
              except in the case of the death, resignation, or removal of any
              director.

     B.       Subject to the rights of the holders of any series of Preferred
              Stock then outstanding, newly created directorships resulting from
              any increase in the authorized number of directors or any
              vacancies in the Board of Directors resulting from death,
              resignation or other cause (other than removal from office by a
              vote of the stockholders) may be filled only by a majority vote of
              the directors then in office, though less than a quorum, and
              directors so chosen shall hold office for a term expiring at the
              next annual meeting of stockholders at which the term of office of
              the class to which they have been elected expires, and until their
              respective successors are elected, except in the case of the
              death, resignation, or removal of any director. No decrease in the
              number of directors constituting the Board of Directors shall
              shorten the term of any incumbent director.


     C.       Subject to the rights of the holders of any series of Preferred
              Stock then outstanding, any directors, or the entire Board of
              Directors, may be removed from office at any time, with or without
              cause, but only by the affirmative vote of the holders of at least
              a majority of the voting power of all of the then outstanding
              shares of capital stock of the Corporation entitled to vote
              generally in the election of directors, voting together as a
              single class. Vacancies in the Board of Directors resulting from
              such removal may be filled by a majority of the directors then in
              office, though less than a quorum, or by the stockholders as
              provided in Section 1 above. Directors so chosen shall hold office
              for a term expiring at the next annual


                                        3



              meeting of stockholders at which the term of office of the class
              to which they have been elected expires, and until their
              respective successors are elected, except in the case of the
              death, resignation, or removal of any director.

     SEVENTH: The Board of Directors is expressly empowered to adopt,
     -------  amend or repeal Bylaws of the Corporation. Any adoption, amendment
              or repeal of Bylaws of the Corporation by the Board of Directors
              shall require the approval of a majority of the total number of
              authorized directors (whether or not there exist any vacancies in
              previously authorized directorships at the time any resolution
              providing for adoption, amendment or repeal is presented to the
              Board). The stockholders shall also have power to adopt, amend or
              repeal the Bylaws of the Corporation. Any adoption, amendment or
              repeal of Bylaws of the Corporation by the stockholders shall
              require, in addition to any vote of the holders of any class or
              series of stock of the Corporation required by law or by this
              Certificate of Incorporation, the affirmative vote of the holders
              of at least sixty-six and two-thirds percent (66-2/3%) of the
              voting power of all of the then outstanding shares of the capital
              stock of the Corporation entitled to vote generally in the
              election of directors, voting together as a single class.

     EIGHTH:  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 involved intentional misconduct or a 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.

              If the Delaware General Corporation Law is hereafter amended to
              authorize the further elimination or limitation of the liability
              of a director, then the liability of a director of the Corporation
              shall be eliminated or limited to the fullest extent permitted by
              the Delaware General Corporation Law, as so amended.

              Any repeal or modification of the foregoing provisions of this
              Article EIGHTH by the stockholders of the Corporation shall not
              adversely affect any right or protection of a director of the
              Corporation existing at the time of such repeal or modification.


                                        4



     NINTH:   The Corporation reserves the right to amend or repeal any
     -----    provision contained in this Certificate of Incorporation in the
              manner prescribed by the laws of the State of Delaware and all
              rights conferred upon stockholders are granted subject to this
              reservation; provided, however, that, notwithstanding any other
                           --------  -------
              provision of this Certificate of Incorporation or any provision of
              law which might otherwise permit a lesser vote or no vote, but in
              addition to any vote of the holders of any class or series of the
              stock of this Corporation required by law or by this Certificate
              of Incorporation, the affirmative vote of the holders of at least
              66-2/3% of the voting power of all of the then outstanding shares
              of the capital stock of the Corporation entitled to vote generally
              in the election of directors, voting together as a single class,
              shall be required to amend or repeal this Article NINTH, Article
              FIFTH, Article SIXTH, Article SEVENTH or Article EIGHTH.

     IN WITNESS WHEREOF, the Corporation has caused this Restated Certificate to
be signed by a duly authorized officer on this 16th day of February, 2000.
