qualifications, limitations or restrictions thereof, so far as they are not
inconsistent with the provisions of this Amended and Restated Certificate of
Incorporation and to the fullest extent now or hereafter permitted by the laws
of Delaware.

          SEVENTH: The Board of Directors of the Corporation shall be governed
by the following:

               A. NUMBER OF DIRECTORS, TENURE AND QUALIFICATIONS. Except as
     provided pursuant to Paragraph D of this Article Seventh, the number of
     Directors constituting the Board of Directors of the Corporation shall be
     the number set forth in the By-Laws of the Corporation, but in no case
     shall be less than three (3). The Board of Directors shall be and is
     divided into three classes, designated Class I, Class II and Class III.
     Each class shall consist, as nearly as possible, of one-third of the total
     number of Directors, with the terms of office of the directors of one class
     expiring each year. Each Director shall serve for a term ending on the date
     of the third annual meeting following the annual meeting at which such
     Director was elected; provided, however, the term of the Class II directors
     serving as of the date of adoption of this Amended and Restated Certificate
     of Incorporation by the stockholders of the Corporation (the "Date of
     Adoption") shall expire on the date of the first annual meeting of
     stockholders held after the Date of Adoption, the term of the Class III
     directors serving as of the Date of Adoption shall expire on the date of
     the second annual meeting of stockholders held after the Date of Adoption,
     and the term of the Class I directors serving as of the Date of Adoption
     shall expire on the date of the third annual meeting of stockholders held
     after the Date of Adoption. Each Director shall hold office until the
     annual meeting for the year in which his term expires and until such
     Director's successor shall be elected and qualified, subject, however, to
     such Director's earlier death, resignation, disqualification or removal
     from office.

               B. VACANCIES. Except as provided pursuant to Paragraph D of this
     Article Seventh, any vacancy on the Board of Directors, whether resulting
     from an increase in

                                        3
<Page>

     the number of Directors fixed by or pursuant to the By-Laws of the
     Corporation or resulting from death, resignation, disqualification, removal
     or otherwise, other than a vacancy with respect to a Director elected as
     provided pursuant to Paragraph D of this Article Seventh shall be filled by
     the vote of the majority of the Directors then in office (excluding
     Directors, if any, elected as provided pursuant to Paragraph D of this
     Article Seventh), even if less than a quorum, or by a sole remaining
     Director. Any Director so elected to fill any vacancy on the Board of
     Directors, including a vacancy created by an increase in the number of
     Directors, shall hold office for the remaining term of Directors of the
     class to which he has been elected and until his successor shall be elected
     and shall qualify.

               C. REMOVAL OF DIRECTORS. Exclusive of Directors, if any, elected
     as provided pursuant to Paragraph D of this Article Seventh, a Director of
     the Corporation may be removed from office prior to the expiration of his
     term of office at any time, but only for cause and only by the affirmative
     vote of a majority of the outstanding shares of capital stock of the
     Corporation entitled to vote with respect to the election of such Director
     at a meeting of the stockholders duly called for such purpose.

               D. DIRECTORS ELECTED BY PREFERENCE SHARES. Notwithstanding the
     foregoing, whenever the holders of any one or more classes or series of
     Preference Shares issued by the Corporation shall have the right, voting
     pursuant to the terms of such Preference Shares, to elect Directors at an
     annual or special meeting of stockholders, the election, term of office,
     filling of vacancies and other features of such Directorships shall be
     governed by the terms of such Preference Shares. Unless expressly provided
     by such terms, Directors so elected shall not be divided into classes and
     during the prescribed terms of office of such Directors the Board of
     Directors shall consist of such Directors in addition to the number of
     Directors determined as provided in Paragraph A of this Article Seventh.

               E. STOCKHOLDER NOMINATIONS. Advance notice of stockholder
     nominations for the election of Directors shall be given in the manner
     provided in the By-Laws of the Corporation.

          EIGHTH: Elections of Directors need not be by written ballot unless
the By-Laws of the Corporation provide otherwise.

                                        4
<Page>

          NINTH: The Board of Directors shall have the power to adopt, amend,
restate, change or repeal the By-Laws of the Corporation or any provision
thereof.

          TENTH: 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 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.

          ELEVENTH: Any action required or permitted to be taken at any annual
or special meeting of stockholders of the Corporation may be taken at an annual
or special meeting or by consent in writing by the stockholders of the
Corporation; provided, that action may not be taken by means of a consent in
writing unless such consent in unanimous.

          TWELFTH: Whenever a compromise or arrangement is proposed between this
Corporation and its creditors or any class of them and/or between this
Corporation and its stockholders or any class of them, any court of equitable
jurisdiction within the State of Delaware may, on the application in a summary
way of this Corporation or of any creditor or stockholder thereof or on the
application of any receiver or receivers appointed for this Corporation under
the provisions of Section 291 of Title 8 of the Delaware Code or on the
application of trustees in dissolution or of any receiver or receivers appointed
for this Corporation under the provisions of Section 279 of Title 8 of the
Delaware Code order a meeting of the creditors or class of creditors, and/or of
the stockholders or class of stockholders of this Corporation, as the case may
be, to be summoned in such manner as the said court directs. If a majority in
number representing three-fourths in value of the creditors or class of
creditors, and/or of the stockholders or class of stockholders of this
Corporation, as the case may be, agree to any compromise or arrangement and to
any reorganization of this Corporation as consequence of such compromise or
arrangement, the said compromise or arrangement and the said reorganization
shall, if sanctioned by the court to which the said application has been made,
by binding on all the creditors or class of creditors, and/or on all the
stockholders or class of stockholders, of this Corporation, as the case may be,
