ARTICLE V.
ELECTION OF DIRECTORS

(A)

Subject to Article V, paragraph (F) hereof, the number of authorized members of the Board of Directors shall be determined from time to time by resolution adopted by the affirmative vote of a majority of the total number of directors which the Company would have if there were no vacancies but shall not be fewer than seven directors and not more than eleven directors.  Election of directors need not be by written ballot.

(B)

The directors, other than those directors elected by the holders of any series of Preferred Stock as provided for or fixed pursuant to the terms of any Certificate of Designations relating to such series of Preferred Stock, shall be divided into three classes, designated Class I, Class II and Class III, and each class shall consist, as nearly as may be possible, of one-third of the total number of directors constituting the Board of Directors.  Each director shall serve for a term ending on the date of the third annual meeting of stockholders following the annual meeting at which such director was elected; provided, however, that the initial directors assigned to Class I shall serve for a term ending on the date of the first annual meeting next following May 18, 2010, the initial directors assigned to Class II shall serve for a term ending on the date of the second annual meeting next following May 18, 2010 and the initial directors assigned to Class III shall serve for a term ending on the date of the third annual meeting next following May 18, 2010.  The Board of Directors may assign members of the Board of Directors already in office to such classes.

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 director 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 except as otherwise provided in this Certificate of Incorporation (including

3

any Certificate of Designation relating to any series of Preferred Stock) relating to additional directors elected by the holders of one or more series of Preferred Stock.

(C)

A director shall hold office until the annual meeting of stockholders for the year in which his or her term expires and until his or her successor shall be elected and shall qualify, subject, however, to prior death, resignation, retirement, disqualification or removal from office.

(D)

Subject to the rights of the holders of any series of Preferred Stock then outstanding, vacancies resulting from death, resignation, retirement, disqualification, removal from office or otherwise, and newly created directorships resulting from any increase in the number of authorized directors, may be filled only by the affirmative vote of a majority of the remaining directors, though less than a quorum of the Board of Directors, and a director so chosen shall hold office for a term expiring at the annual meeting of stockholders at which the term of office of the class to which such director has been elected expires and until such director’s successor has been duly elected and qualified.

(E)

Subject to the rights of the holders of any series of Preferred Stock then outstanding, any director may be removed, but only for cause, at any special meeting of the stockholders called for that purpose, by the affirmative vote of the holders of 66⅔ percent of the voting power of the outstanding shares of the Company entitled to vote generally in the election of directors.

(F)

During any period when the holders of any series of Preferred Stock have the right to elect additional directors as provided for or fixed pursuant to the provisions of any Certificate of Designations relating to such series of Preferred Stock, then upon commencement and for the duration of the period during which such right continues (i) the then otherwise total authorized number of directors of the Company shall automatically be increased by such specified number of directors, and the holders of such Preferred Stock shall be entitled to elect the additional directors so provided for or fixed pursuant to said provisions, and (ii) each such additional director shall serve until such director’s successor shall have been duly elected and qualified, or until such director’s right to hold such office terminates pursuant to said provisions, whichever occurs earlier, subject to his earlier death, disqualification, resignation or removal.  Except as otherwise provided by the Board of Directors in the resolution or resolutions establishing such series, whenever the holders of any series of Preferred Stock having such right to elect additional directors are divested of such right pursuant to the provisions of such stock, the terms of office of all such additional directors elected by the holders of such stock, or elected to fill any vacancies resulting from the death, resignation, disqualification or removal of such additional directors, shall forthwith terminate and the total and authorized number of directors of the Company shall be reduced accordingly.

ARTICLE VI.
AMENDMENT OF BYLAWS

The Bylaws may be adopted, amended or repealed (A) by the Board of Directors or (B) by the affirmative vote of a majority of the outstanding voting power entitled to vote generally in the election of directors; provided, however, that in the case of clause (B), notice of the proposed amendment is contained in the notice of the meeting.  In addition to any vote

4

required by any other provision of the Bylaws, this Certificate of Incorporation or any applicable law, if such amendment is to be adopted by the stockholders, the affirmative vote of holders of eighty percent of the outstanding voting power entitled to vote generally in the election of directors, voting together as a single class, shall be required for any amendment to the Bylaws that amends or repeals, or adopts any provisions inconsistent with Section 2.7(F), Article III, Article VIII or Section 9.10 thereof.

ARTICLE VII.
BUSINESS COMBINATIONS

(A)

The affirmative vote of the holders of not less than eighty percent of the outstanding voting power entitled to vote generally in the election of directors shall be required for the approval or authorization of any “Business Combination” (as hereinafter defined) involving a “Related Person” (as hereinafter defined); provided, however, that the eighty percent voting requirement shall not be applicable if:

(1)

The “Continuing Directors” (as hereinafter defined) of the Company by a two-thirds vote have expressly approved such Business Combination either in advance of or subsequent to such Related Person having become a Related Person; or

(2)

The following conditions are satisfied:

stock is not listed on such exchange, on the principal United States securities exchange registered under the Exchange Act on which such stock is listed, or, if such stock is not listed on any such exchange, the highest closing bid quotation with respect to a share of such stock during the 30-day period preceding the date in question on the National Association of Securities Dealers, Inc.
