In case the number of shares of any series shall be so decreased, the shares constituting such decrease shall resume the status which they had prior to the adoption of the resolution originally fixing the number of shares of such series.

2. Provisions Applicable to All Series of Preferred Stock and to the Common Stock

Each stockholder of the corporation who at the time possesses voting power for any purpose shall be entitled to one vote for each share of such stock standing in his name on the books of the corporation.

4

TENTH. Whenever a compromise or arrangement is proposed between the corporation and its creditors or any class of them and/or between the 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 the corporation or of any creditor or stockholder thereof, or on the application of any receiver or receivers appointed for the 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 the 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 the 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 the corporation, as the case may be, agree to any compromise or arrangement and to any reorganization of the 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, be binding on all the creditors or class of creditors, and/or on all the stockholders or class of stockholders, of the corporation, as the case may be, and also on the corporation.

ELEVENTH. A. Meetings of stockholders may be held outside the State of Delaware, if the by-laws so provide. The books of the corporation may be kept (subject to any provision contained in the statutes) outside the State of Delaware at such place or places as may be designated from time to time by the Board of Directors or in the by-laws of the corporation. Elections of directors need not be by ballot unless the by-laws of the corporation shall so provide.

B. The number of directors shall be determined by the Board of Directors or the stockholders, provided, however, that the number thereof shall never be less than twelve nor greater than fifteen. A director need not be a stockholder. The directors shall be divided into three classes, designated Class I, Class II, and Class III, as nearly equal in number as the then total number of directors permits. At the 1985 annual meeting of stockholders, Class I directors shall be elected for a one-year term, Class II directors for a two-year term and Class III directors for a three-year term. At each succeeding annual meeting of stockholders beginning in 1986, successors to the class of directors whose term expires at that annual meeting shall be elected for a three-year term. If the number of directors is changed, any increase or decrease shall be apportioned among the classes so as to maintain the number of directors in each class as nearly equal as possible, and any additional directors of any class elected to fill a vacancy resulting from an increase in such class shall hold office for a term that shall coincide with the remaining term of that class, but in no case will a decrease in the number of directors shorten the term of any incumbent director. A director shall hold office until the annual meeting for the year in which his term expires and until his successor shall be elected and shall qualify, subject, however, to prior death, resignation, retirement, disqualification or removal from office. Any vacancy on the Board of Directors, including any vacancy that results from an increase in the number of directors may be filled by a majority of the Board of Directors then in office, although less than a quorum, or by a sole remaining director. Any director elected to fill a vacancy shall have the same remaining term as that of his predecessor.

Notwithstanding the foregoing, whenever the holders of any one or more classes or series of Preferred Stock issued by the corporation shall have the right, voting separately by class or series, 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 this Certificate of Incorporation applicable thereto, and such directors so elected shall not be divided into classes pursuant to this Article unless expressly provided by such terms.

Any amendment, change or repeal of this Article, or any other amendment to this Certificate of Incorporation that will have the effect of permitting circumvention of or modifying this paragraph B of ARTICLE ELEVENTH, shall require the favorable vote, at a stockholders’ meeting, of the holders of at least 80 of the then-outstanding shares of stock of the corporation entitled to vote.

TWELFTH. Notwithstanding anything in this Certificate of Incorporation to the contrary, any action required or permitted to be taken at a meeting of stockholders may be taken without a meeting only if 80 or more of the voting power of the stockholders entitled to vote thereon consent thereto in writing.

5

Any amendment, change or repeal of this ARTICLE TWELFTH, or any other amendment to this Certificate of Incorporation that will have the effect of permitting circumvention or modifying this ARTICLE TWELFTH, shall require the favorable vote, at a stockholders’ meeting, of the holders of at least 80 of the then-outstanding shares of stock of the corporation entitled to vote.

THIRTEENTH. 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 stockholders herein are granted subject to this reservation.

FOURTEENTH. To the fullest extent permitted by Delaware statutory or decisional law, as amended or interpreted, no director of the Corporation shall be personally liable to the Corporation or its shareholders for monetary damages for breach of fiduciary duty as a director. This Article Fourteenth does not affect the availability of equitable remedies for breach of fiduciary duties.
