Certain Provisions of Our Certificate of Incorporation and Bylaws and Delaware Law

General

Certain provisions of our Certificate of Incorporation, our Bylaws and Section 203 of the DGCL may have the effect of impeding the acquisition of control of the Company by means of a tender offer, a proxy contest, open market purchases or otherwise in a transaction not approved by our Board of Directors. These provisions are designed to reduce the vulnerability of the Company to an unsolicited takeover attempt which is unfair or coercive to our stockholders.

Number of Members of Board of Directors

The number of directors that constitute our entire Board of Directors will be fixed from time to time exclusively by our Board of Directors pursuant to a resolution adopted by a majority of the Board of Directors. The Certificate of Incorporation provides, however, that the Board of Directors shall consist of not less than three nor more than fifteen directors. This provision would permit our Board of Directors, if it so elects, to increase the number of members of the Board of Directors to a number not to exceed fifteen directors and fill the resulting vacancies with its own designees.

Exclusive Forum Clause

Our Bylaws provide that unless we consent in writing to the selection of an alternative forum, the sole and exclusive forum for (i) any internal corporate claims within the meaning of the DGCL, as well as (ii) (A) any derivative action or proceeding brought on our behalf, (B) any action asserting a claim of breach of a fiduciary duty owed by any of our directors, officers or other employees to us or to our stockholders, (C) any action asserting a claim arising pursuant to any provision of the DGCL, or (D) any action asserting a claim governed by the internal affairs doctrine, shall be a state or federal court located within the state of Delaware, in all cases subject to the court’s having personal jurisdiction over the indispensable parties named as defendants. Any person or entity purchasing or otherwise acquiring any interest in shares of our capital stock will be deemed to have notice of and consented to the provisions covering the forum for adjudication of disputes in our Bylaws.

Advance Notice of Proposals and Nominations

Our Bylaws provide that at any annual meeting of stockholders, the only nominations of persons for election to our Board of Directors to be considered and the only business to be conducted will be the nominations made or business brought before the meeting (i) pursuant to our notice of meeting delivered at the direction of our Board of Directors, (ii) by or at the direction of our Board of Directors or (iii) by a stockholder who is a stockholder of record at the time of delivery of the notice provided for in the Bylaws, who is entitled to vote at the meeting and who complies with the advance notice procedures set forth in the Bylaws. For nominations and other business to be properly brought before an annual meeting of stockholders pursuant to clause (iii) above, the stockholder must deliver written notice to our principal office not less than 90 days nor more than 180 days prior to the annual meeting. However, if notice of the meeting is not given, or made by public disclosure, to the stockholders at least 100 days prior to the date of an annual meeting, notice by the stockholder must be received not later than the close of business on the tenth day following the day on which such notice of the date of the meeting was mailed or public disclosure was made. Similar procedures apply to nominations of persons for election to our Board of Directors at any special meeting of the stockholders called for the purposes of electing directors. Except for director nominations, stockholders are not entitled to submit business to be considered or acted upon at any special meeting of the stockholders. Notice by a stockholder to us requesting inclusion of a proposal in our proxy statement pursuant to Rule 14a-8 under the Exchange Act will be considered timely if received by our Secretary prior to the deadline specified in Rule 14a-8. Our Bylaws also specify the form and content of a stockholder’s notice. These provisions may prevent or hinder stockholders from bringing matters before an annual meeting or special meeting of stockholders or from nominating candidates for election as directors at such meetings of stockholders.

Limits on Special Meetings

Except as otherwise required by law, a special meeting of the stockholders may be called only by the Chairman of the Board or in his absence by the President, by the Board of Directors, or by the Secretary, at the request in writing of a majority of the members of our Board of Directors. A special meeting of the stockholders may not be called by our stockholders.

Action by Stockholders

Any action that may be taken by our stockholders must be taken at a duly called annual or special meeting of such holders and not by written consent in lieu of a meeting.

Classification of Our Board of Directors

Our Board of Directors, which is comprised of eleven directors, is divided into three classes of directors based on their term of office: Class I, Class II and Class III. The directors in each such class hold office for staggered terms of three years each. At present, we have three Class I directors, four Class II directors and five Class III directors. Each director generally serves for a term ending on the third annual meeting of stockholders following the annual meeting of stockholders at which such director was elected until his or her successor has been duly elected and qualified. This classification of our Board of Directors limits the

3

ability of majority stockholders or persons holding proxies to vote a majority of our shares to change control of our Board of Directors in fewer than two annual stockholder meetings. This limitation could have the effect of discouraging a potential acquiror from making a tender offer or otherwise attempting to obtain control of the Company and could thus increase the likelihood that incumbent directors will retain their positions.

Supermajority Voting

Our Bylaws generally provide that stockholder action is effective upon majority vote, except in the case of contested director elections and circumstances requiring supermajority voting. Contested elections are subject to a plurality voting standard. In addition, the affirmative vote of the holders of record of at least 66 ⅔% of the combined voting power of all of our outstanding stock entitled to vote, voting together as a single class, is required to alter, amend, rescind or repeal any of our Bylaws or to alter, amend, rescind or repeal the following provisions of our Certificate of Incorporation or to adopt any provision inconsistent therewith:

• the provisions relating to the Board of Directors, including the division of the Board of Directors into three classes;

• the provision that special meetings of the stockholders may only be called by certain officers or by the Board of Directors and may not be called by the stockholders;

• the provision that stockholders may not act by written consent;

• the provision authorizing the Board of Directors to adopt, alter, amend and repeal the Bylaws; and

• the provision requiring a 66 ⅔% vote of stockholders to amend the Bylaws.

Section 203 of the Delaware General Corporation Law

We are subject to Section 203 of the Delaware General Corporation Law. The provisions of Section 203 prohibit a publicly-held Delaware corporation from engaging in certain “business combinations” with an “interested stockholder” for a period of three years after the date that the person became an interested stockholder, unless one of the following conditions is satisfied:

• prior to the date that the person became an interested stockholder, the transaction or business combination that resulted in the person becoming an interested stockholder is approved by our Board of Directors;

• upon consummation of the transaction that resulted in the stockholder becoming an interested stockholder, the interested stockholder owned at least 85% of our voting stock outstanding at the time the transaction commenced, other than statutorily excluded shares; or

4

• on or after the date that the person became an interested stockholder, the business combination is approved by our Board of Directors and by the holders of at least two-thirds of our outstanding voting stock, excluding voting stock owned by the interested stockholder.

Generally, a “business combination” includes a merger, asset or stock sale or other transaction resulting in a financial benefit to the interested stockholder. Subject to certain exceptions, an “interested stockholder” is a person who together with that person’s affiliates and associates owns, or within the previous three years did own, 15% or more of our voting stock.

Under some circumstances, Section 203 makes it more difficult for a person who would be an “interested stockholder” to effect various business combinations with a corporation for a three-year period, although the stockholders may elect to exclude a corporation from the restrictions imposed under Section 203. Our Certificate of Incorporation does not exclude us from the restrictions imposed under Section 203.
