The registered office of the Corporation in the State of Delaware shall be located at the Corporation Trust Center, 1209 Orange Street, in the City of Wilmington, Delaware, County of New Castle. The name of the Corporation’s registered agent at such address shall be The Corporation Trust Company. The registered office and/or registered agent of the Corporation may be changed from time to time by action of the board of directors (the “Board” or the “Board of Directors”).

     Section 2. Other Offices. The Corporation may also have offices at such other places, both within and without the State of Delaware, as the Board of Directors may from time to time determine or the business of the Corporation may require.

ARTICLE II

MEETINGS OF STOCKHOLDERS

     Section 1. Place and Time of Meetings. An annual meeting of the stockholders shall be held each year within one hundred fifty (150) days after the close of the immediately preceding fiscal year of the Corporation for the purpose of electing directors and conducting such other proper business as may come before the meeting, or at such other time as may be determined by the chief executive officer or president of the Corporation. The date, time and place of the annual meeting shall be determined by the chief executive officer or the president of the Corporation; provided, that if the chief executive officer or the president does not act, the Board of Directors shall determine the date, time and place of such meeting. At the annual meeting, stockholders shall elect directors and transact such other business as properly may be brought before the annual meeting pursuant to Section 12 of this Article II.

     Section 2. Special Meetings. Special meetings of the stockholders may only be called in the manner provided in the certificate of incorporation.

     Section 3. Place of Meetings. The Board of Directors may designate any place, either within or without the State of Delaware, as the place of meeting for any annual meeting or for any special meeting. If no designation is made, or if a special meeting be otherwise called, the place of meeting shall be the principal executive office of the Corporation. If for any reason any annual meeting shall not be held during any year, the business thereof may be transacted at any special meeting of the stockholders.

     Section 4. Notice. Whenever stockholders are required or permitted to take action at a meeting, written or printed notice stating the place, date, time, and, in the case of special meetings, the purpose or purposes, of such meeting, shall be given to each stockholder entitled to vote at such meeting not less than ten (10) nor more than sixty (60) days before the date of the meeting. If mailed, such notice shall be deemed to be delivered when deposited in the United States mail, postage prepaid, addressed to the stockholder at his, her or its address as the same appears on the records of the Corporation. If sent by facsimile transmission, such notice shall be deemed to be delivered when the facsimile transmission is promptly confirmed by telephone confirmation thereof. Attendance of a person at a meeting shall constitute a waiver of notice of such meeting, except when the person attends for the express purpose of objecting at the beginning of the meeting to the transaction of any business because the meeting is not lawfully called or convened.

     Section 5. Stockholders List. The officer having charge of the stock ledger of the Corporation shall make, at least ten (10) days before every meeting of the stockholders, a complete list of the stockholders entitled to vote at such meeting arranged in alphabetical order, showing the address of each stockholder and the number of shares

registered in the name of each stockholder. Such list shall be open to the examination of any stockholder, for any purpose germane to the meeting, during ordinary business hours, for a period of at least ten (10) days prior to the meeting, either at a place within the city where the meeting is to be held, which place shall be specified in the notice of the meeting or, if not so specified, at the place where the meeting is to be held. The list shall also be produced and kept at the time and place of the meeting during the whole time thereof, and may be inspected by any stockholder who is present.

     Section 6. Quorum. The holders of a majority of the outstanding shares of capital stock entitled to vote at the meeting, present in person or represented by proxy, shall constitute a quorum at all meetings of the stockholders, except as otherwise provided by statute or by the certificate of incorporation. If a quorum is not present, the holders of a majority of the shares present in person or represented by proxy at the meeting, and entitled to vote at the meeting, may adjourn the meeting to another time and/or place. When a specified item of business requires a vote by a class or series (if the Corporation shall then have outstanding shares of more than one class or series) voting as a class or series, the holders of a majority of the shares of such class or series shall constitute a quorum (as to such class or series) for the transaction of such item of business.

     Section 7. Adjourned Meetings. When a meeting is adjourned to another time and place, notice need not be given of the adjourned meeting if the time and place thereof are announced at the meeting at which the adjournment is taken. At the adjourned meeting the Corporation may transact any business which might have been transacted at the original meeting. If the adjournment is for more than thirty (30) days, or if after the adjournment a new record date is fixed for the adjourned meeting, a notice of the adjourned meeting shall be given to each stockholder of record entitled to vote at the meeting.

     Section 8. Vote Required. All matters and questions (other than the election of directors) shall, unless otherwise provided by the certificate of incorporation of the Corporation, these by-laws, the rules or regulations of any stock exchange applicable to the Corporation, as otherwise provided by law or pursuant to any regulation applicable to the Corporation or its securities, be decided by the affirmative vote of the holders of a majority in voting power of the shares of stock of the Corporation which are present in person or by proxy and entitled to vote thereon.

     Section 9. Voting Rights. Except as otherwise provided by the General Corporation Law of the State of Delaware, by the certificate of incorporation of the Corporation or any amendments thereto or these by-laws, every stockholder shall at every meeting of the stockholders be entitled to cast one (1) vote in person or by proxy for each share of common stock held by such stockholder.

     Section 10. Proxies. Each stockholder entitled to vote at a meeting of stockholders or to express consent or dissent to corporate action in writing without a meeting may authorize another person or persons to act for him or her by proxy, but no such proxy shall be voted or acted upon after three (3) years from its date, unless the proxy provides for a longer period. A proxy shall be irrevocable if it states that it is irrevocable and if, and only as long as, it is coupled with an interest sufficient in law to support an irrevocable power. A proxy may be made irrevocable regardless of whether the interest with which it is coupled is an interest in the stock itself or an interest in the Corporation generally. Any proxy is suspended when the person granting the proxy is present at a meeting of stockholders and elects to vote, except that when such proxy is coupled with an interest and the fact of the interest appears on the face of the proxy, the agent named in the proxy shall have all voting and other rights referred to in the proxy, notwithstanding the presence of the person granting the proxy. At each meeting of the stockholders, and before any voting commences, all proxies submitted at or before the meeting shall be submitted to the secretary or a person designated by the secretary, and no shares may be represented or voted under a proxy that has been found to be invalid or irregular.

     Section 11. Action by Written Consent. Unless otherwise provided in the certificate of incorporation, any action required to be taken at any annual or special meeting of stockholders of the Corporation, or any action which may be taken at any annual or special meeting of such stockholders, may be taken without a meeting, without prior notice and without a vote, if a consent or consents in writing, setting forth the action so taken and bearing the dates of signature of the stockholders who signed the consent or consents, shall be signed by the holders of outstanding stock having not less than the minimum number of votes that would be necessary to authorize or take such action at a meeting at which all shares entitled to vote thereon were present and voted and shall be delivered to the Corporation by delivery to its registered office in the state of Delaware, or the Corporation’s principal place of business, or an officer or agent of the Corporation having custody of the book or books in which proceedings of meetings of the stockholders are recorded. Delivery made to the Corporation’s registered office shall be by hand or by certified or registered mail, return receipt requested provided, however,

that no consent or consents delivered by certified or registered mail shall be deemed delivered until such consent or consents are actually received at the registered office. All consents properly delivered in accordance with this section shall be deemed to be recorded when so delivered. No written consent shall be effective to take the corporate action referred to therein unless, within sixty (60) days of the earliest dated consent delivered to the Corporation as required by this section, written consents signed by the holders of a sufficient number of shares to take such corporate action are so recorded. Prompt notice of the taking of the corporate action without a meeting by less than unanimous written consent shall be given to those stockholders who have not consented in writing and who, if the action had been taken at a meeting, would have been entitled to notice of the meeting if the record date for such meeting had been the date that written consents signed by a sufficient number of holders to take the action were delivered to the Corporation as provided herein. Any action taken pursuant to such written consent or consents of the stockholders shall have the same force and effect as if taken by the stockholders at a meeting thereof.

     Section 12. Business Brought Before an Annual Meeting. At an annual meeting of the stockholders, only such business shall be conducted as shall have been properly brought before the meeting. To be properly brought before an annual meeting, business must be (i) specified in the notice of meeting (or any supplement thereto) given by or at the direction of the Board of Directors, (ii) brought before the meeting by or at the direction of the Board of Directors or (iii) otherwise properly brought before the meeting by a stockholder who was a stockholder of record at the time of giving notice provided for in this by-law. For business to be properly brought before an annual meeting by a stockholder, the stockholder must have given timely notice thereof in writing to the secretary of the Corporation. To be timely, a stockholder’s notice must be delivered to or mailed and received at the principal executive offices of the Corporation, not less than sixty (60) days nor more than ninety (90) days prior to the first anniversary of the prior year’s annual meeting; provided, however, that in the event that the annual meeting is changed by more than thirty (30) days from such anniversary date, notice by the stockholder to be timely must be not later than the close of business on the 10th day following the date on which such notice of the date of the annual meeting was mailed or such public announcement was made. A stockholder’s notice to the secretary shall set forth as to each matter the stockholder proposes to bring before the annual meeting as to the stockholder giving the notice and any Stockholder Associated Person (as defined below): (i) a brief description of the business desired to be brought before the annual meeting, (ii) the name and address, as they appear on the Corporation’s books, of the stockholder proposing such business, (iii) any material interest in such business (iv) the class and number of shares of the Corporation which are beneficially owned by the stockholder (v) the nominee holder for, and number of, shares owned beneficially but not of record by such person, (vi) whether and the extent to which any hedging or other transaction or series of transactions has been entered into by or on behalf of, or any other agreement, arrangement or understanding (including any derivative or short positions, profit interests, options or borrowed or loaned shares) has been made, the effect or intent of which is to mitigate loss to or manage risk or benefit of share price changes for, or to increase or decrease the voting power of, such person with respect to any share of stock of the Corporation, (vii) to the extent known by the stockholder giving the notice, the name and address of any other stockholder supporting the proposal of business on the date of such stockholder’s notice, (viii) a description of all arrangements or understandings between or among such persons in connection with the proposal of such business by such stockholder, (ix) a representation that the stockholder giving the notice intends to appear in person or by proxy at the annual meeting to bring such business before the meeting, (x) notice whether such person intends to solicit proxies in connection with the proposed matter and (xi) any other information that is required to be provided by the stockholder pursuant to Regulation 14A under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), in his capacity as a proponent to a stockholder proposal. Any information required pursuant to this paragraph shall be supplemented to speak as of the record date for the meeting by the stockholder giving the notice not later than ten (10) days after such record date. Notwithstanding anything in these by-laws to the contrary, no business shall be conducted at an annual meeting except in accordance with the procedures set forth in this section. The presiding officer of an annual meeting shall, if the facts warrant, determine and declare to the meeting that business was not properly brought before the meeting and in accordance with the provisions of this section; if he should so determine, he shall so declare to the meeting and any such business not properly brought before the meeting shall not be transacted. For purposes of this section, “public announcement” shall mean disclosure in a press release reported by Dow Jones News Service, Associated Press or a comparable national news service. Nothing in this section shall be deemed to affect any rights of stockholders to request inclusion of proposals in the Corporation’s proxy statement pursuant to Rule 14a-8 under the Exchange Act. A “Stockholder Associated Person” of any stockholder shall mean (i) any person acting in concert, directly or indirectly, with such stockholder and (ii) any person controlling, controlled by or under common control with such stockholder or any Stockholder Associated Person.

ARTICLE III

DIRECTORS

     Section 1. General Powers. The business and affairs of the Corporation shall be managed by or under the direction of the Board of Directors. In addition to such powers as are herein and in the certificate of incorporation expressly conferred upon it, the Board of Directors shall have and may exercise all the powers of the Corporation, subject to the provisions of the laws of Delaware, the certificate of incorporation and these by-laws.

     Section 2. Number, Election and Term of Office. The number of directors which shall constitute the first Board of Directors shall be six. Thereafter, subject to any rights of the holders of any series of Preferred Stock to elect additional directors under specified circumstances, the number of directors which shall constitute the Board of Directors shall be fixed from time to time by resolution adopted by the affirmative vote of a majority of the total number of directors then in office. The directors shall be elected by a plurality of the votes of the shares present in person or represented by proxy at the annual meeting of the stockholders and entitled to vote in the election of directors; provided that, whenever the holders of any class or series of capital stock of the Corporation are entitled to elect one or more directors pursuant to the provisions of the certificate of incorporation of the Corporation (including, but not limited to, for purposes of these by-laws, pursuant to any duly authorized certificate of designation), such directors shall be elected by a plurality of the votes of such class or series present in person or represented by proxy at the meeting and entitled to vote in the election of such directors. The directors shall be elected in this manner at the annual meeting of stockholders, except as provided in Section 4 of this Article III, and each director shall hold office until a successor is duly elected and qualified or until his or her earlier death, resignation or removal as hereinafter provided.

     Section 3. Removal and Resignation. Any director or the entire Board of Directors may be removed at any time, with or without cause, by the holders of a majority of the shares then entitled to vote at an election of directors. Whenever the holders of any class or series are entitled to elect one or more directors by the provisions of the Corporation’s certificate of incorporation, the provisions of this section shall apply, in respect to the removal without cause of a director or directors so elected, to the vote of the holders of the outstanding shares of that class or series and not to the vote of the outstanding shares as a whole. Any director may resign at any time upon written notice to the corporation.

     Section 4. Vacancies. Subject to any rights of holders of any series of Preferred Stock to fill such newly created directorships or vacancies, any newly created directorships resulting from any increase in the authorized number of directors and any vacancies in the Board of Directors resulting from death, resignation, disqualification or removal from office for cause shall, unless otherwise provided by law or by resolution approved by the affirmative vote of a majority of the total number of directors then in office, be filled only by resolution approved by the affirmative vote of a majority of the total number of directors then in office. Any director so chosen shall hold office until his successor shall have been duly elected and qualified, unless he shall resign, die, become disqualified or be removed for cause.

     Section 5. Annual Meetings. The annual meeting of each newly elected Board of Directors shall be held without other notice than this by-law immediately after, and at the same place as, the annual meeting of stockholders, unless otherwise provided by resolution of the Board.

     Section 6. Other Meetings; Notice. Meetings, other than the annual meeting, of the Board may be called upon one day’s prior written notice to all directors stating the purpose or purposes thereof. Such notice shall be effective upon receipt, in the case of personal delivery or facsimile transmission, and three business days after deposit with the U.S. Postal Service, postage prepaid, if mailed.

     Section 7. Chairman of the Board, Quorum, Required Vote and Adjournment. The Board of Directors shall elect, by the affirmative vote of a majority of the total number of directors then in office, a chairman of the board, who shall preside at all meetings of the stockholders and Board of Directors at which he or she is present and shall have such powers and perform such duties as the Board of Directors may from time to time prescribe. If the chairman of the board is not present at a meeting of the stockholders or the Board of Directors, the chief executive officer (if the chief executive officer is a director and is not also the chairman of the board) shall preside at such meeting, and, if the chief executive officer is not present at such meeting, a majority of the directors present at such meeting shall elect one of their members to so preside. A majority of the total number of directors then in office shall constitute a quorum for the transaction of business. Unless by express provision of

an applicable law, the certificate of incorporation or these by-laws a different vote is required, the vote of a majority of directors present at a meeting at which a quorum is present shall be the act of the Board of Directors. If a quorum shall not be present at any meeting of the Board of Directors, the directors present thereat may adjourn the meeting from time to time, without notice other than announcement at the meeting, until a quorum shall be present.

     Section 8. Nominations.

     (a) Only persons who are nominated in accordance with the procedures set forth in these by-laws shall be eligible to serve as directors. Nominations of persons for election to the Board of Directors of the Corporation may be made at a meeting of stockholders (i) by or at the direction of the Board of Directors or (ii) by any stockholder of the Corporation who was a stockholder of record at the time of giving of notice provided for in this by-law, who is entitled to vote generally in the election of directors at the meeting and who shall have complied with the notice procedures set forth below in Section 8(b).

     (b) In order for a stockholder to nominate a person for election to the Board of Directors of the Corporation at a meeting of stockholders, such stockholder shall have delivered timely notice of such stockholder’s intent to make such nomination in writing to the secretary of the Corporation. To be timely, a stockholder’s notice shall be delivered to or mailed and received at the principal executive offices of the Corporation (i) in the case of an annual meeting, not less than 60 nor more than 90 days prior to the first anniversary of the preceding year’s annual meeting; provided, however, that in the event that the date of the annual meeting is changed by more than 30 days from such anniversary date, notice by the stockholder to be timely must be so received not later than the close of business on the 10th day following the earlier of the day on which notice of the date of the meeting was mailed or public disclosure of the meeting was made, and (ii) in the case of a special meeting at which directors are to be elected, not later than the close of business on the 10th day following the earlier of the day on which notice of the date of the meeting was mailed or public announcement of the meeting was made. Such stockholder’s notice shall set forth as to each person whom the stockholder proposes to nominate for election or re-election as a director and as to the stockholder giving the notice and any Stockholder Associated Person: (A) the name, age, business address, residence address and record address of such person, (B) the principal occupation or employment of such person, (C) the class and number of shares of the corporation which are beneficially owned by such person, (D) a description of all arrangements or understandings between or among such persons (naming such person or persons) pursuant to which the nominations are to be made by the stockholder and any relationship between or among the stockholder giving notice and any Stockholder Associated Person, on the one hand, and each proposed nominee, on the other hand, (E) the nominee holder for, and number of, shares owned beneficially but not of record by such person, (F) whether and the extent to which any hedging or other transaction or series of transactions has been entered into by or on behalf of, or any other agreement, arrangement or understanding (including any derivative or short positions, profit interests, options or borrowed or loaned shares) has been made, the effect or intent of which is to mitigate loss to or manage risk or benefit of share price changes for, or to increase or decrease the voting power of, such person with respect to any share of stock of the Corporation, (G) to the extent known by the stockholder giving the notice, the name and address of any other stockholder supporting the nominee for election or reelection as a director on the date of such stockholder’s notice, (H) a representation that the stockholder intends to appear in person or by proxy at the meeting to nominate the persons named in its notice and (I) any other information relating to such person that is required to be disclosed in solicitations of proxies for election of directors, or is otherwise required, in each case pursuant to Regulation 14A under the Exchange Act (including without limitation the nominee’s written consent to being named in the proxy statement, if any, as a nominee and to serving as a director if elected). Any information required pursuant to this paragraph shall be supplemented to speak as of the record date for the meeting by the stockholder giving the notice not later than ten (10) days after such record date. The Corporation may require any proposed nominee to furnish such other information as may reasonably be required by the Corporation to determine the eligibility of such proposed nominee to serve as an independent director of the Corporation or that could be material to a reasonable stockholder’s understanding of the independence, or lack thereof, of such nominee. At the request of the Board of Directors, any person nominated by the Board of Directors for election as a director shall furnish to the secretary of the Corporation that information required to be set forth in a stockholder’s notice of nomination which pertains to the nominee.

     (c) No person shall be eligible to serve as a director of the Corporation unless nominated in accordance with the procedures set forth in this section. The chairman of the meeting shall, if the facts warrant, determine and declare to the meeting that a nomination was not made in accordance with the procedures prescribed by this section, and if he should so determine, he shall so declare to the meeting and the defective nomination shall be disregarded. A stockholder seeking to nominate a person to serve as a director must also comply with all applicable requirements of the Exchange Act, and the rules and regulations thereunder with respect to the matters set forth in this section.

     Section 9. Telephonic Meetings; Written Consents. Except as may otherwise be provided by applicable law, any action required or permitted to be taken at any meeting of the Board or any committee thereof may be taken without a meeting pursuant to a written consent, in compliance with the General Corporation Law of the State of Delaware and such written consent is filed with the minutes of the proceedings of the Board or such committee. Any meeting of the Board or any committee thereof may be held by conference telephone or similar communication equipment, so long as all Board or committee members participating in the meeting can hear one another clearly, and participation in a meeting by use of conference telephone or similar communication equipment shall constitute presence in person at such meeting.

     Section 10. Committees. The Board of Directors may, by resolution passed by a majority of the total number of directors then in office, designate one or more committees, each committee to consist of one or more of the directors of the Corporation, which to the extent provided in such resolution or these by-laws shall have

and may exercise the powers of the Board of Directors in the management and affairs of the Corporation except, as otherwise limited by law. The Board of Directors may designate one or more directors as alternate members of any committee, who may replace any absent or disqualified member at any meeting of the committee. Such committee or committees shall have such name or names as may be determined from time to time by resolution adopted by the Board of Directors. Each committee shall keep regular minutes of its meetings and report the same to the Board of Directors when required.

     Section 11. Committee Rules. Each committee of the Board of Directors may fix its own rules of procedure and shall hold its meetings as provided by such rules, except as may otherwise be provided by a resolution of the Board of Directors designating such committee. Unless otherwise provided in such a resolution, the presence of at least a majority of the members of the committee shall be necessary to constitute a quorum. Unless otherwise provided in such a resolution, in the event that a member and that member’s alternate, if alternates are designated by the Board of Directors, of such committee is or are absent or disqualified, the member or members thereof present at any meeting and not disqualified from voting, whether or not such member or members constitute a quorum, may unanimously appoint another member of the Board of Directors to act at the meeting in place of any such absent or disqualified member.

     Section 12. Waiver of Notice and Presumption of Assent. Any member of the Board of Directors or any committee thereof who is present at a meeting shall be conclusively presumed to have waived notice of such meeting except when such member attends for the express purpose of objecting at the beginning of the meeting to the transaction of any business because the meeting is not lawfully called or convened. Such member shall be conclusively presumed to have assented to any action taken unless his or her dissent shall be entered in the minutes of the meeting or unless his or her written dissent to such action shall be filed with the person acting as the secretary of the meeting before the adjournment thereof or shall be forwarded by registered mail to the secretary of the Corporation immediately after the adjournment of the meeting. Such right to dissent shall not apply to any member who voted in favor of such action.

     Section 5. Compensation. Compensation of all executive officers shall be fixed by the Board of Directors, and no officer shall be prevented from receiving such compensation by virtue of his or her also being a director of the Corporation.

     Section 6. The Chief Executive Officer. The chief executive officer, if there shall be one, shall, in the absence of the chairman of the board, preside at all meetings of the stockholders at which he is present; subject to the powers of the Board of Directors, shall have general charge of the business, affairs and property of the Corporation, and control over its officers, agents and employees; and shall see that all orders and resolutions of

ARTICLE V

INDEMNIFICATION OF OFFICERS, DIRECTORS AND OTHERS

     Section 1. Nature of Indemnity. Each person who was or is made a party or is threatened to be made a party to or is involved in any action, suit or proceeding, whether civil, criminal, administrative or investigative (hereinafter a “proceeding”), by reason of the fact that he, or a person of whom he or she is the legal representative, is or was a director or officer, of the Corporation or, while a director or officer of the Corporation, is or was serving at the request of the Corporation as a director, officer, employee, fiduciary, or agent of another corporation or of a partnership, joint venture, trust or other enterprise, shall be indemnified and held harmless by the Corporation to the fullest extent which it is empowered to do so unless prohibited from doing so by the General Corporation Law of the State of Delaware, as the same exists or may hereafter be amended against all expense, liability and loss (including attorneys’ fees actually and reasonably incurred by such person in connection with such proceeding) and such indemnification shall inure to the benefit of his or her heirs, executors and administrators; provided, however, that, except as provided in Section 2 hereof, the Corporation shall indemnify any such person seeking indemnification in connection with a proceeding initiated by such person only if such proceeding was authorized by the Board of Directors of the Corporation. The right to indemnification conferred in this Article V shall be a contract right. The Corporation may, by action of its Board of Directors, provide indemnification to employees and agents of the Corporation with the same scope and effect as the foregoing indemnification of directors and officers.

     Section 2. Procedure for Indemnification of Directors and Officers. Any indemnification of a director or officer of the Corporation under Section 1 of this Article V or advance of expenses under Section 5 of this Article V shall be made promptly, and in any event within 30 days, upon the written request of the director or officer. If a determination by the Corporation that the director or officer is entitled to indemnification pursuant to this Article V is required, and the Corporation fails to respond within thirty days to a written request for indemnity, the Corporation shall be deemed to have approved the request. If the Corporation denies a written request for indemnification or advancing of expenses, in whole or in part, or if payment in full pursuant to such request is not made within 30 days, the right to indemnification or advances as granted by this Article V shall be enforceable by the director or officer in any court of competent jurisdiction. Such person’s costs and expenses incurred in connection with successfully establishing his or her right to indemnification, in whole or in part, in any such action shall also be indemnified by the Corporation. It shall be a defense to any such action (other than an action brought to enforce a claim for expenses incurred in defending any proceeding in advance of its final disposition where the required undertaking, if any, has been tendered to the Corporation) that the claimant has not met the standards of conduct which make it permissible under the General Corporation Law of the State of Delaware for the Corporation to indemnify the claimant for the amount claimed, but the burden of such defense shall be on the Corporation. Neither the failure of the Corporation (including its Board of Directors, independent legal counsel, or its stockholders) to have made a determination prior to the commencement of such action that indemnification of the claimant is proper in the circumstances because he or she has met the applicable standard of conduct set forth in the General Corporation Law of the State of Delaware, nor an actual determination by the Corporation (including its Board of Directors, independent legal counsel, or its stockholders) that the claimant has not met such applicable standard of conduct, shall be a defense to the action or create a presumption that the claimant has not met the applicable standard of conduct.

     Section 3. Article Not Exclusive. The rights to indemnification and the payment of expenses incurred in defending a proceeding in advance of its final disposition conferred in this Article V shall not be exclusive of any other right which any person may have or hereafter acquire under any statute, provision of the certificate of incorporation, by-law, agreement, vote of stockholders or disinterested directors or otherwise.

     Section 4. Insurance. The Corporation may purchase and maintain insurance on its own behalf and on behalf of any person who is or was a director, officer, employee, fiduciary, or agent of the Corporation or is or was serving at the request of the Corporation as a director, officer, employee or agent of another corporation, partnership, joint venture, trust or other enterprise against any liability asserted against him or her and incurred by him or her in any such capacity, whether or not the Corporation would have the power to indemnify such person against such liability under this Article V.

     Section 5. Expenses. Expenses incurred by any person described in Section 1 of this Article V in defending a proceeding shall be paid by the Corporation in advance of such proceeding’s final disposition upon receipt of an undertaking by or on behalf of the director or officer to repay such amount if it shall ultimately be determined

that he or she is not entitled to be indemnified by the Corporation. Such expenses incurred by other employees and agents may be so paid upon such terms and conditions, if any, as the Board of Directors deems appropriate.

     Section 6. Employees and Agents. Persons who are not covered by the foregoing provisions of this Article V and who are or were employees or agents of the Corporation, or who are or were serving at the request of the Corporation as employees or agents of another corporation, partnership, joint venture, trust or other enterprise, may be indemnified to the extent authorized at any time or from time to time by the Board of Directors.

     Section 7. Contract Rights. The provisions of this Article V shall be deemed to be a contract right between the Corporation and each director or officer who serves in any such capacity at any time while this Article V and the relevant provisions of the General Corporation Law of the State of Delaware or other applicable law are in effect, and any repeal or modification of this Article V or any such law shall not affect any rights or obligations then existing with respect to any state of facts or proceeding then existing.

     Section 8. Merger or Consolidation. For purposes of this Article V, references to “the Corporation” shall include, in addition to the resulting corporation, any constituent corporation (including any constituent of a constituent) absorbed in a consolidation or merger which, if its separate existence had continued, would have had power and authority to indemnify its directors, officers, and employees or agents, so that any person who is or was a director, officer, employee or agent of such constituent corporation, or is or was serving at the request of such constituent corporation as a director, officer, employee or agent of another corporation, partnership, joint venture, trust or other enterprise, shall stand in the same position under this Article V with respect to the resulting or surviving corporation as he or she would have with respect to such constituent corporation if its separate existence had continued.

ARTICLE VI

CERTIFICATES OF STOCK

     Section 1. Form. The shares of stock of the Corporation shall be represented by certificates unless the Board of Directors shall by resolution or resolutions provide that some or all of any or all classes or series of stock of the Corporation shall be uncertificated shares of stock. Notwithstanding the adoption of such a resolution by the Board of Directors, every holder of stock represented by a certificate and, upon request, every holder of uncertificated shares shall be entitled to have a certificate, signed by, or in the name of the Corporation by the chief executive officer, any vice-president and the secretary or an assistant secretary of the Corporation, certifying the number of shares owned by such holder in the Corporation. If such a certificate is countersigned (i) by a transfer agent or an assistant transfer agent other than the Corporation or its employee or (ii) by a registrar, other than the Corporation or its employee, the signature of any such chief executive officer, president, vice president, secretary or assistant secretary may be facsimiles. In case any officer or officers who have signed, or whose facsimile signature or signatures have been used on, any such certificate or certificates shall cease to be such officer or officers of the Corporation whether because of death, resignation or otherwise before such certificate or certificates have been delivered by the Corporation, such certificate or certificates may nevertheless be issued and delivered as though the person or persons who signed such certificate or certificates or whose facsimile signature or signatures have been used thereon had not ceased to be such officer or officers of the Corporation. All certificates for shares shall be consecutively numbered or otherwise identified. The name of the person to whom the shares represented thereby are issued, with the number of shares and date of issue, shall be entered on the books of the Corporation. Shares of stock of the Corporation represented by a certificate shall only be transferred on the books of the Corporation by the holder of record thereof or by such holder’s attorney duly authorized in writing, upon surrender to the Corporation of the certificate or certificates for such shares endorsed by the appropriate person or persons, with such evidence of the authenticity of such endorsement, transfer, authorization, and other matters as the Corporation may reasonably require, and accompanied by all necessary stock transfer stamps. In that event, it shall be the duty of the Corporation to issue a new certificate to the person entitled thereto, cancel the old certificate or certificates, and record the transaction on its books. Uncertificated shares of the Corporation shall only be transferred on the books of the Corporation upon delivery of proper instructions to transfer such shares by the holder of record thereof or by such holder’s attorney duly authorized in writing, upon presentment of proper evidence of succession, assignation or authority to transfer in accordance with the customary procedures for transferring shares in uncertificated form. The Board of Directors may appoint a bank or trust company organized under the laws of the United States or any state thereof to act as its transfer agent or registrar, or both in connection with the transfer of any class or series of securities of the Corporation.

     Section 2. Lost Certificates. The Board of Directors may direct a new certificate or certificates to be issued in place of any certificate or certificates previously issued by the Corporation alleged to have been lost, stolen, or destroyed, upon the making of an affidavit of that fact by the person claiming the certificate of stock to be lost, stolen, or destroyed. When authorizing such issue of a new certificate or certificates, the Board of Directors may, in its discretion and as a condition precedent to the issuance thereof, require the owner of such lost, stolen, or destroyed certificate or certificates, or his or her legal representative, to give the Corporation a bond sufficient to indemnify the Corporation against any claim that may be made against the Corporation on account of the loss, theft or destruction of any such certificate or the issuance of such new certificate.

     Section 3. Fixing a Record Date for Stockholder Meetings. In order that the Corporation may determine the stockholders entitled to notice of or to vote at any meeting of stockholders or any adjournment thereof, the Board of Directors may fix a record date, which record date shall not precede the date upon which the resolution fixing the record date is adopted by the Board of Directors, and which record date shall not be more than sixty (60) nor less than ten (10) days before the date of such meeting. If no record date is fixed by the Board of Directors, the record date for determining stockholders entitled to notice of or to vote at a meeting of stockholders shall be the close of business on the next day preceding the day on which notice is given, or if notice is waived, at the close of business on the day next preceding the day on which the meeting is held. A determination of stockholders of record entitled to notice of or to vote at a meeting of stockholders shall apply to any adjournment of the meeting; provided, however, that the Board of Directors may fix a new record date for the adjourned meeting.

     Section 4. Fixing a Record Date for Action by Written Consent. In order that the Corporation may determine the stockholders entitled to consent to corporate action in writing without a meeting, if permitted by the certificate of incorporation, the Board of Directors may fix a record date, which record date shall not precede the date upon which the resolution fixing the record date is adopted by the Board of Directors, and which date shall not be more than ten days after the date upon which the resolution fixing the record date is adopted by the Board of Directors. If no record date has been fixed by the Board of Directors, the record date for determining stockholders entitled to consent to corporate action in writing without a meeting, when no prior action by the Board of Directors is required by statute, shall be the first date on which a signed written consent setting forth the action taken or proposed to be taken is delivered to the Corporation by delivery to its registered office in the State of Delaware, its principal place of business, or an officer or agent of the Corporation having custody of the book in which proceedings of meetings of stockholders are recorded. Delivery made to the Corporation’s registered office shall be by hand or by certified or registered mail, return receipt requested. If no record date has been fixed by the Board of Directors and prior action by the Board of Directors is required by statute, the record date for determining stockholders entitled to consent to corporate action in writing without a meeting shall be at the close of business on the day on which the Board of Directors adopts the resolution taking such prior action.

     Section 5. Fixing a Record Date for Other Purposes. In order that the Corporation may determine the stockholders entitled to receive payment of any dividend or other distribution or allotment or any rights or the stockholders entitled to exercise any rights in respect of any change, conversion or exchange of stock, or for the purposes of any other lawful action, the Board of Directors may fix a record date, which record date shall not precede the date upon which the resolution fixing the record date is adopted, and which record date shall be not more than sixty (60) days prior to such action. If no record date is fixed, the record date for determining stockholders for any such purpose shall be at the close of business on the day on which the Board of Directors adopts the resolution relating thereto.

     Section 6. Registered Stockholders. Prior to the surrender to the Corporation of the certificate or certificates for a share or shares of stock with a request to record the transfer of such share or shares, the Corporation may treat the registered owner as the person entitled to receive dividends, to vote, to receive notifications, and otherwise to exercise all the rights and powers of an owner. Except as otherwise required by applicable law, the Corporation shall not be bound to recognize any equitable or other claim to or interest in such share or shares on the part of any other person, whether or not it shall have express or other notice thereof.

     Section 7. Subscriptions for Stock. Unless otherwise provided for in the subscription agreement, subscriptions for shares shall be paid in full at such time, or in such installments and at such times, as shall be determined by the Board of Directors. Any call made by the Board of Directors for payment on subscriptions shall be uniform as to all shares of the same class or as to all shares of the same series. In case of default in the payment of any installment or call when such payment is due, the Corporation may proceed to collect the amount due in the same manner as any debt due the Corporation.

ARTICLE VII

The Board of Directors shall have authority, as provided by law, to determine that only a part of the consideration which shall be received by the Corporation for the shares of its stock which it shall issue from time to time, shall be capital; provided, however, that, if all the shares issued shall be shares having a par value, the amount of the part of such consideration so determined to be capital shall be equal to the aggregate par value of such shares.

Exhibit 99.1

FOR IMMEDIATE RELEASE:

PACKAGING CORPORATION OF AMERICA DECLARES QUARTERLY DIVIDEND AND UPDATES BUSINESS CONDITIONS

Lake Forest, IL December 4, 2008 — Packaging Corporation of America (NYSE: PKG) announced that its Board of Directors approved a regular quarterly dividend of $0.30 per share on its common stock. The quarterly dividend of $0.30 per share will be paid to shareholders of record as of December 15, 2008 with a payment date of January 15, 2009. Future declaration of quarterly dividends, and the establishment of future record and payment dates, are subject to the final determination by PCA’s Board of Directors.

PCA also announced that business conditions have continued to be weaker during the fourth quarter, and demand for containerboard and corrugated products is significantly lower than expected entering the quarter. As a result, PCA currently expects that approximately 90,000 tons of market related, mill downtime or slowbacks will be required in the fourth quarter. Through November 30, about half of the downtime/slowbacks has occured, and the remaining half is scheduled throughout December. With lower demand and higher than anticipated downtime, PCA expects fourth quarter earnings to be below the company’s previous guidance of $0.35 per share.

PCA is the fifth largest producer of containerboard and corrugated packaging products in the United States with sales of $2.3 billion in 2007. PCA operates four paper mills and 67 corrugated product plants in 26 states across the country.
