Certain Anti-Takeover Provisions of Our Certificate of Incorporation, By-Laws and Delaware General Corporation Law

General

Our Certificate of Incorporation, our By-Laws and the Delaware General Corporation Law contain certain provisions that could delay or make more difficult an acquisition of control of us that is not approved by our Board of Directors, whether by means of a tender offer, open-market purchases, a proxy contest or otherwise. These provisions have been implemented to enable us to conduct our business in a manner that will foster our long-term growth without disruption caused by the threat of a takeover not deemed by our Board of Directors to be in the best interests of us and our shareholders. These provisions could have the effect of discouraging third parties from making proposals involving an acquisition or change of control of us, although such a proposal, if made, might be considered desirable by a majority of our shareholders. These provisions also may have the effect of making it more difficult for third parties to cause the replacement of our current management without the concurrence of our Board of Directors. Set forth below is a description of the provisions contained in our Certificate of Incorporation, our By-Laws and the Delaware General Corporation Law that could impede or delay an acquisition of control of us that our Board of Directors has not approved. This description is intended as a summary only and is subject to, and qualified in its entirety by reference to, our Certificate of Incorporation and our By-Laws, as well as the Delaware General Corporation Law.

Number of Directors; Removal; Filling of Vacancies

Our Certificate of Incorporation and By-Laws provide that the number of directors shall not be fewer than eight or more than 13, the exact number to be fixed by resolution of our Board of Directors from time to time. Directors may be removed by shareholders with or without cause.

Our Certificate of Incorporation and By-Laws provide that vacancies on the Board of Directors may be filled only by a majority vote of the remaining directors or by the sole remaining director.

Shareholder Action

2

Our Certificate of Incorporation provides that shareholder action may be taken only at an annual or special meeting of shareholders. Therefore, shareholders may not act by written consent. Our Certificate of Incorporation and By-Laws provide that special meetings of shareholders may be called only by our Board of Directors or, upon the written request of the holders owning of record continuously for a period of at least one year prior to the date of the requested meeting not less than 25% of the voting power of all outstanding shares of our common stock, by our Secretary, subject to certain additional requirements set forth in our By-Laws.

Advance Notice for Shareholder Proposals or Nominations at Meetings

Our By-Laws establish an advance notice procedure for shareholder proposals to be brought before any annual or special meeting of shareholders and for nominations by shareholders of candidates for election as directors at an annual meeting or a special meeting at which directors are to be elected. Subject to any other applicable requirements, including Rule 14a-8 under the Exchange Act, only such business may be conducted at an annual meeting of shareholders as has been:

• specified in the notice of the annual meeting given by, or at the direction of, our Board of Directors;

• brought before the meeting by, or at the direction of, our Board of Directors;

• brought before the meeting by a shareholder who has given our Secretary timely written notice, in proper form, of the shareholder’s intention to bring that business before the meeting, where such shareholder is a shareholder of record on the date the notice is delivered to our Secretary, is entitled to vote at the meeting on such business and complies with the advance notice procedure of our By-Laws; or

• brought pursuant to the proxy access provision of our By-Laws.

With respect to a special meeting of the shareholders, only such business may be conducted at the meeting as has been specified in the notice of such special meeting. The person presiding at such annual or special meeting has the authority to make such determinations. Only persons who are nominated by, or at the direction of, our Board of Directors, or who are nominated by a shareholder who has given timely written notice, in proper form, to our Secretary prior to a meeting at which directors are to be elected will be eligible for election as a director.

To be timely, notice of nominations or other business to be brought before any annual meeting must be delivered to our Secretary not less than 90 days nor more than 120 days prior to the first anniversary date of the annual meeting for the preceding year; provided, however, that if the annual meeting is not scheduled to be held within a period that commences 30 days before and ends 30 days after such anniversary date, such advance notice shall be given by the later of:

• the close of business on the date 90 days prior to the date of the annual meeting; or

• the close of business on the tenth day following the date that the annual meeting date is first publicly announced or disclosed.

3

If we call a special meeting of shareholders for the purpose of electing directors, notice of nominations must be delivered to our Secretary not later than the close of business on the tenth day following the date that the special meeting date and either the names of nominees or the number of directors to be elected is first publicly announced or disclosed.

Any shareholder who gives notice of any nomination of directors or other proposal must provide the following information:

• whether the shareholder is providing the notice at the request of a beneficial holder of shares, whether the shareholder, any such beneficial holder or any nominee has any agreement, arrangement or understanding with, or has received any financial assistance, funding or other consideration from any other person with respect to the investment by the shareholder or such beneficial holder of our stock or the matter the notice relates to, and the details thereof, including the name of such other person (the shareholder, any beneficial holder on whose behalf the notice is being delivered, any nominees listed in the notice and any persons with whom such agreement, arrangement or understanding exists or from whom such assistance has been obtained are referred to as “Interested Persons”);

• the name and address of all Interested Persons;

• a complete description of all of our or our subsidiaries’ equity securities and debt instruments, whether held in the form of loans or capital market instruments, beneficially owned by all Interested Persons;

• whether and the extent to which any hedging, derivative or other transaction is in place or has been entered into within the six months preceding the date of delivery of the notice by or for the benefit of any Interested Person with respect to us or our subsidiaries, or any of our or our subsidiaries’ respective securities, debt instruments or credit ratings, the effect or intent of which transaction is to give rise to gain or loss as a result of changes in the trading price of such securities or debt instruments or changes in our or our subsidiaries’ credit ratings or any of our or our subsidiaries’ respective securities or debt instruments (or, more generally, changes in our or our subsidiaries’ perceived creditworthiness), or to increase or decrease the voting power of such Interested Person, and if so, a summary of the material terms thereof; and

• a representation that the shareholder is a holder of record of our stock that would be entitled to vote at the meeting and intends to appear in person or by proxy at the meeting to propose the matter set forth in the notice.

Any notice relating to the nomination of directors must also contain:

• the information regarding each nominee required by paragraphs (a), (e) and (f) of Item 401 of Regulation S-K adopted by the SEC;

• each nominee’s signed consent to serve as a director if elected; and

4

• information as to whether each nominee is eligible for consideration as an independent director under the relevant standards contemplated by Item 407(a) of Regulation S-K.

Any notice with respect to a matter other than the nomination of directors must contain:

• the text of the proposal to be presented, including the text of any resolutions to be proposed for consideration by shareholders; and

• a brief written statement of the reasons the shareholder favors the proposal.

Proxy Access Provision of our By-Laws

Our By-Laws contain “proxy access” provisions, which give an eligible shareholder (or group of up to 20 such shareholders) owning 3% or more of our outstanding shares of common stock (the “Minimum Number”) continuously throughout the three-year period preceding and including the date of submission of the nomination notice and continuing to own at least the Minimum Number through the date of the annual meeting, the right to nominate up to the greater of two nominees or 20% of the board of directors (rounded down to the nearest whole number) and have those nominees included in our proxy statement. To be timely, any nomination notice must be delivered to our secretary at our principal executive office no earlier than 150 calendar days and no later than 120 calendar days before the anniversary of the date that the Company mailed its proxy statement for the prior year’s annual meeting of shareholders; provided, however, that if (and only if) the annual meeting is not scheduled to be held within a period that commences 30 days before such anniversary date and ends 30 days after the anniversary of the prior year’s meeting date (an annual meeting date outside such period being referred to herein as an “Other Meeting Date”), the nomination notice shall be given by the later of the close of business on the date that is 180 days prior to such Other Meeting Date or the tenth day following the date such Other Meeting Date is first publicly announced or disclosed. The complete proxy access provisions for director nominations are set forth in our By-Laws.

Amendments to By-Laws

Our By-Laws provide that our Board of Directors or the holders of a majority of the shares of our capital stock entitled to vote at an annual or special meeting of shareholders have the power to amend, alter, change or repeal our By-Laws.

Exclusive Forum Provision of our By-Laws

Our By-Laws provide that, unless we consent in writing to the selection of an alternative forum, the sole and exclusive forum for certain actions shall be a state court located within the State of Delaware (or, if no state court located within the State of Delaware has jurisdiction, the federal district court for the District of Delaware). Those actions include: (i) any derivative action or proceeding brought on behalf of us, (ii) any action asserting a claim of breach of fiduciary duty owed by any of our directors or our officers or other employees to us or our shareholders, (iii) any action asserting a claim against us or any of our directors or our officers or other employees arising pursuant to any provision of the Delaware General Corporation Law or our Certificate of

5

Incorporation or By-Laws (in each case, as amended from time to time), or (iv) any action asserting a claim against us or any of our directors or our officers or other employees governed by the internal affairs doctrine.

Amendment of the Certificate of Incorporation

Any proposal to amend, alter, change or repeal any provision of our Certificate of Incorporation requires approval by the affirmative vote of a majority of the voting power of all of the shares of our capital stock entitled to vote on such matters, with the exception of certain provisions of our Certificate of Incorporation that require a vote of 80% or more of such voting power.

Provisions of Our Certificate of Incorporation Related to Business Combinations

Our Certificate of Incorporation provides that, in addition to any affirmative vote required by law or any other provision of our Certificate of Incorporation, “business combinations” (generally defined as mergers, consolidations, sales of substantially all assets, issuances or transfers of securities with a fair market value of more than $1.0 million, and other significant transactions) involving us or any of our subsidiaries and involving or proposed by an “interested shareholder” (generally defined for purposes of these provisions as a person who beneficially owns more than 10% of our outstanding voting capital stock, or is an affiliate of ours and who within the prior two years was such a 10% beneficial owner or who has succeeded to any shares of our voting capital stock that were owned by an interested shareholder within the prior two years) or an affiliate of an interested shareholder require the approval of at least 80% of our then outstanding capital stock, voting as a class, provided that business combinations approved by our continuing directors (as defined in our Certificate of Incorporation) or satisfying certain “fair price” and procedure provisions (generally requiring that shareholders receive consideration at least equal to the highest price paid by the interested shareholder for shares of our common stock within the prior two years) are not subject to this 80% vote requirement. Our Certificate of Incorporation provides that these provisions cannot be amended or repealed, and that any inconsistent provision may not be adopted, without the affirmative vote of at least 80% of our then outstanding capital stock, voting as a single class.

Anti-Greenmail Provisions of Our Certificate of Incorporation

Our Certificate of Incorporation provides that any purchase by us of shares of our voting capital stock from an “interested shareholder” (generally defined for purposes of these provisions as a person who beneficially owns 5% or more of our outstanding voting capital stock, or is an affiliate of ours and who within the prior two years was such a 5% beneficial owner or who has succeeded to any shares of our voting capital stock that were owned by an interested shareholder within the prior two years) at a price higher than the market price at the time, other than pursuant to an offer to the holders of all outstanding shares of the class, requires the approval of the percentage of our then outstanding voting capital stock at least equal to the sum of the percentage held by the interested shareholder plus a majority of the remaining shares, voting as a single class. Our Certificate of Incorporation provides that these provisions cannot be amended or repealed, and that any inconsistent provision may not be adopted, without the affirmative vote of at least 80% of our outstanding capital stock, voting as a single class.

6

Provisions of Our Certificate of Incorporation While There is a 40% Shareholder

Our Certificate of Incorporation provides that in any election of directors on or after the date on which any “40% shareholder” (generally defined for purposes of these provisions as a person who beneficially owns 40% or more of the voting power of our outstanding voting capital stock, or is an affiliate of ours and who within the prior two years was such a 40% beneficial owner or who has succeeded to any shares of our voting capital stock that were owned by an interested shareholder within the prior two years) becomes a 40% shareholder, and until such time as no 40% shareholder any longer exists, there shall be cumulative voting for the election of directors so that any holder of our voting capital stock will be entitled to as many votes as shall equal the number of directors to be elected multiplied by the number of votes to which the holder would otherwise be entitled and such holder may cast all of such votes for a single director, or distribute such votes among as many candidates as such holder sees fit. In any such election of directors, one or more candidates may be nominated by a majority of our disinterested directors. With respect to any person so nominated, or nominated by a person who is the beneficial owner of shares of our voting capital stock having a market price of at least $100,000, we are required to include certain information with respect to such nominees (generally on equal terms with other nominees of our Board of Directors and management) in our proxy statement or other materials with respect to the election of directors. Our Certificate of Incorporation provides that these provisions cannot be amended or repealed, and that any inconsistent provision may not be adopted, without the affirmative vote of at least 80% of our outstanding capital stock, voting as a single class.

Preferred Stock

Our Certificate of Incorporation authorizes our Board of Directors to issue one or more series of preferred stock by resolution and to determine, with respect to any series of preferred stock, the terms and rights of such series. The authorized shares of preferred stock, as well as the authorized shares of our common stock, are available for issuance without further action by our shareholders, unless such action is required by applicable law or the rules of the New York Stock Exchange or any other stock exchange on which our securities may be listed. Although our Board of Directors has no intention at the present time of doing so, it does have the power (subject to applicable law) to issue a series of preferred stock that, depending on the terms of such series, could impede the completion of a merger, tender offer or other takeover attempt. For instance, subject to applicable law, such series of preferred stock might impede a business combination by including class voting rights that would enable the holder to block such a transaction. Holders of preferred stock will not have any preemptive rights.

Delaware General Corporation Law

Under Section 203 of the Delaware General Corporation Law (“Section 203”), certain “business combinations” (generally defined to include mergers or consolidations between a Delaware corporation and an interested shareholder, transactions with an interested shareholder involving the assets or stock of the corporation or its majority-owned subsidiaries and transactions that increase the interested shareholder’s percentage ownership of stock) between a publicly held Delaware corporation and an “interested shareholder” (generally defined as those shareholders who become beneficial owners of 15% or more of a Delaware corporation’s voting stock or their affiliates) are

7

prohibited for a three-year period following the date that such shareholder became an interested shareholder. This three-year waiting period does not apply when:

• the corporation has elected in its certificate of incorporation not to be governed by Section 203;

• either the business combination or the proposed acquisition of stock resulting in the person becoming an interested shareholder was approved by the corporation’s board of directors before the other party to the business combination became an interested shareholder;

• upon consummation of the transaction that made such person an interested shareholder, the interested shareholder owned at least 85% of the voting stock of the corporation outstanding at the commencement of the transaction (excluding voting stock owned by officers who are also directors or held in employee benefit plans in which the employees do not have a confidential right to tender or vote stock held by the plan); or

• the business combination was approved by the corporation’s board of directors and also was authorized by two-thirds of the voting stock that the interested shareholder did not own.

Under certain circumstances, Section 203 makes it more difficult for a person who would be an interested shareholder to effect various business combinations with a corporation for a three-year period, although the shareholders may elect to exclude a corporation from the restrictions imposed thereunder. Our Certificate of Incorporation does not exclude us from the restrictions imposed under Section 203. The provisions of Section 203 may encourage companies interested in acquiring us to negotiate in advance with our Board of Directors because the shareholder approval requirement would be avoided if a majority of the directors then in office approved either the business combination or the transaction that results in the shareholder becoming an interested shareholder. Such provisions also may have the effect of preventing changes in our management. It is possible that such provisions could make it more difficult to accomplish transactions that shareholders otherwise may deem to be in their best interests.
