SHAREHOLDERS

Section 2.1 Place of Meetings. Meetings of shareholders of the Corporation shall be held at any place, if any, either within or without the Commonwealth of Virginia, as may be designated from time to time by the Board of Directors. The Board of Directors may, in its sole discretion, determine that a meeting of shareholders of the Corporation shall not be held at any place, but may instead be held solely by means of remote communication. In the absence of notice to the contrary, meetings of the shareholders of the Corporation shall be held at the principal executive office of the Corporation.

Section 2.2 Annual Meeting. The annual meeting of the shareholders of the Corporation shall be held on such date and at such place, if any, and/or by the means of remote communication, and time as may be fixed by resolution of the Board of Directors from time to time. At the annual meeting of the shareholders of the Corporation, directors shall be elected and any other business may be transacted which is properly brought before the annual meeting in accordance with the procedures set forth in Section 2.14 of these bylaws. Failure to hold any annual meeting as aforesaid shall not constitute, be deemed to be or otherwise effect a forfeiture or dissolution of the Corporation nor shall such failure affect otherwise valid corporate acts.

Section 2.3 Special Meetings. Except as otherwise required by law or provided in the instrument of designation of any series of preferred stock of the Corporation, special meetings of shareholders of the Corporation may be called at any time and from time to time only upon the written request (stating the purpose or purposes of the meeting) of (a) the Board of Directors, (b) the Chairman of the Board of Directors, or (c) the holders of a majority of the total voting power of all the shares of the Corporation entitled to vote generally in the election of directors. Special meetings of the shareholders of the Corporation may not be called by any person, group or entity other than those specifically enumerated in this Section 2.3. The Board of Directors or the Chairman of the Board of Directors shall determine the date, time, and place, if any, and/or means of remote communication, of any special meeting, which shall be stated in a notice of meeting delivered by the Board of Directors. Advance notice of shareholder nominations for the election of directors and of business to be brought by shareholders before any meeting of the shareholders of the Corporation, or any class or series of thereof, shall be given in the manner provided in these bylaws. No business may be transacted at any special meeting of the shareholders of the Corporation other than the business specified in the notice of such meeting.

Section 2.4 Chairman of the Meeting; Conduct of Meetings; Inspection of Elections.

(a) Meetings of shareholders of the Corporation shall be presided over by the chairman of the meeting, who shall be the Chairman of the Board of Directors or, in the absence thereof, such person as the Chairman of the Board of Directors shall appoint, or, in the absence thereof or in the event that the Chairman of the Board of Directors shall fail to make such appointment, any officer of the Corporation appointed by the Board of Directors.

(b) The secretary of any meeting of the shareholders of the Corporation shall be the Secretary or Assistant Secretary, or in the absence thereof, such person as the chairman of the meeting appoints. The secretary of the meeting shall keep the minutes thereof.

(c) The Board of Directors shall be entitled to make such rules or regulations for the conduct of meetings of shareholders of the Corporation as it shall deem necessary, appropriate or convenient from time to time. Subject to such rules and regulations, if any, the chairman of the meeting shall have the right and authority to convene and (for any or no reason) to recess and/or adjourn the meeting, to prescribe such rules, regulations and procedures and to do all acts as, in the judgment of such chairman, are necessary, appropriate or convenient (and not

2

inconsistent with the Articles of Incorporation or these bylaws) for the proper conduct of the meeting, including, without limitation, establishing an agenda of business of the meeting, recognizing shareholders entitled to speak, calling for the necessary reports, stating questions and putting them to a vote, calling for nominations, announcing the results of voting, establishing rules or regulations to maintain order, imposing restrictions on entry to the meeting after the time fixed for commencement thereof and the fixing of the date and time of the opening and closing of the polls for each matter upon which the shareholders of the Corporation will vote at a meeting (and shall announce such at the meeting).

(d) If required by law, the Board of Directors shall appoint one or more inspectors, which inspector or inspectors may include individuals who serve the Corporation in other capacities, including, without limitation, as officers, employees, agents or representatives, to act at a meeting of shareholders of the Corporation and make a written report thereof. One or more persons may be designated as alternate inspectors to replace any inspector who fails to act. If no inspector or alternate has been appointed to act or is able to act at a meeting of shareholders of the Corporation, the chairman of the meeting shall appoint one or more inspectors to act at the meeting. Each inspector, before discharging his or her duties, shall take an oath faithfully to execute the duties of inspector with strict impartiality and according to the best of his or her ability. The inspectors shall have such other duties as may be prescribed by law.

Section 2.5 Notice.

(a) Whenever shareholders of the Corporation are required or permitted to take any action at a meeting (whether special or annual), written notice (unless oral notice is reasonable under the circumstances) stating the place (if any), date, and time of the meeting, the means of remote communication (if any) by which shareholders and proxy holders may be deemed to be present in person and vote at such meeting, the record date for determining the shareholders entitled to vote at the meeting (if such date is different from the record date for shareholders entitled to notice of the meeting) and, in the case of special meetings, the purpose or purposes of such meeting, shall be given to each shareholder of the Corporation entitled to vote at such meeting not fewer than ten (10) nor more than sixty (60) days before the date of the meeting except as otherwise required by law, the Articles of Incorporation or these bylaws. In the case of an annual meeting, the notice need not state the purpose or purposes of the meeting unless the Articles of Incorporation or the Virginia Stock Corporation Act of the Commonwealth of Virginia (as the same exists or may hereafter be amended from time to time, the 'VSCA') requires the purpose or purposes to be stated in the notice of the meeting.

(b) All such notices shall be delivered in writing (unless oral notice is reasonable under the circumstances) or by a form of electronic transmission if receipt thereof has been consented to by the shareholder to whom the notice is given. If mailed, such notice shall be deemed to be delivered when deposited in the United States mail, postage prepaid, addressed to the shareholder at such shareholder's address as it appears on the records of the Corporation. If given by facsimile telecommunication, such notice shall be deemed to be delivered when directed to a number at which the shareholder has consented to receive notice by facsimile. Subject to the limitations of Section 2.6 of these bylaws, if given by electronic transmission, such notice shall be deemed to be delivered: (i) by electronic mail, when directed to an electronic mail address at which the shareholder has consented to receive notice; (ii) if by a posting on an electronic network

3

together with separate written notice to the shareholder of such specific posting delivered by electronic mail or by United States mail, postage prepaid, addressed to the shareholder at such shareholder's address as it appears on the records of the Corporation, upon the later of (x) such posting and (y) the giving of such separate notice; and (iii) if by any other form of electronic transmission, when directed to the shareholder. An affidavit of the Secretary or an Assistant Secretary, the transfer agent of the Corporation or any other agent of the Corporation that the notice has been given shall, in the absence of fraud, be prima facie evidence of the facts stated therein.

(c) Whenever notice is required to be given under any provisions of the VSCA, the Articles of Incorporation or these bylaws, a written waiver thereof, signed by the shareholder entitled to notice, or a written waiver by electronic transmission by the person or entity entitled to notice, whether before or after the time stated therein, shall be deemed equivalent to notice. Neither the business to be transacted at, nor the purpose of, any meeting of the shareholders of the Corporation need be specified in any waiver of notice of such meeting.

(d) Attendance of a shareholder of the Corporation at a meeting of such shareholders shall constitute a waiver of notice of such meeting, except when the shareholder 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.

(e) Whenever notice is required to be given under the VSCA, the Articles of Incorporation or these bylaws to any shareholder with whom communication is unlawful, the giving of such notice to such shareholder shall not be required, and there shall be no duty to apply to any governmental authority or agency for a license or permit to give such notice to such shareholder. Any action or meeting which shall be taken or held without notice to any such shareholder with whom communication is unlawful shall have the same force and effect as if such notice had been duly given. Notwithstanding the other provisions of this Section 2.5, no notice of a meeting of the shareholders of the Corporation need be given to any shareholder if (i) (A) an annual report and proxy statement for two consecutive annual meetings of shareholders or (B) all, and at least two, checks and payment of dividends or interest on securities during a twelve-month period, in either case, have been sent by first-class, United States mail, addressed to the shareholder at his or her address as it appears on the share transfer books of the Corporation, and returned undeliverable and (ii) the Corporation does not have either a current facsimile number or, if such shareholder has consented to electronic delivery pursuant to Section 2.6 of these bylaws, means of electronic transmission for such shareholder. In that event, the obligation of the Corporation to give notice of a shareholders meeting to any such shareholder shall be reinstated once the Corporation has received a new address, facsimile number or means of electronic transmission for such shareholder.

Section 2.6 Notice by Electronic Delivery. Without limiting the manner by which notice otherwise may be given effectively to shareholders of the Corporation pursuant to the VSCA, the Articles of Incorporation or these bylaws, any notice to shareholders of the Corporation given by the Corporation under any provision of the VSCA, the Articles of Incorporation or these bylaws shall be effective if given by a form of electronic transmission consented to by the shareholder of the Corporation to whom the notice is given. Any such consent shall be revocable by the shareholder by written notice to the Secretary. Any such consent shall be deemed revoked if: (i) the Corporation is unable to deliver by electronic transmission two (2) consecutive notices

4

of meetings or of other business given by the Corporation in accordance with such consent; and (ii) such inability becomes known to the Secretary or an Assistant Secretary or to the transfer agent or other person responsible for the giving of notice. However, the inadvertent failure to treat such inability as a revocation shall not invalidate any meeting or other action. For purposes of these bylaws, except as otherwise limited by applicable law, the term 'electronic transmission' means any form of communication not directly involving the physical transmission of paper that creates a record that may be retained, retrieved, and reviewed by a recipient thereof, and that may be directly reproduced in paper form by such a recipient through an automated process.

Section 2.7 Shareholders List. The officer having charge of the stock ledger of the Corporation shall make, at least ten (10) days before every meeting of the shareholders of the Corporation, a complete list of the shareholders entitled to vote at such meeting (provided, however, if the record date for determining the shareholders entitled to vote is less than ten (10) days before the date of the meeting, the list shall reflect the shareholders entitled to vote as of the tenth day before the meeting date), arranged in alphabetical order, showing the address of (and any form of electronic transmission consented to by) each shareholder and the number of shares registered in the name of each shareholder. Such list shall be open to the examination of any shareholder of the Corporation for any purpose germane to the meeting for a period of at least ten (10) days prior to the meeting: (i) on a reasonably accessible electronic network; provided that the information required to gain access to such list is provided with the notice of the meeting; and/or (ii) during ordinary business hours, at the principal place of business of the Corporation. In the event that the Corporation determines to make the list available on an electronic network, the Corporation may take reasonable steps to ensure that such information is available only to shareholders of the Corporation. If the meeting is to be held at a place, then the list shall be produced and kept at the time and place of the meeting during the whole time thereof and may be examined by any shareholder who is present. If the meeting is to be held solely by means of remote communication, then the list shall also be open to the examination of any shareholder during the whole time of the meeting on a reasonably accessible electronic network, and the information required to access such list shall be provided with the notice of the meeting. Refusal or failure to prepare or make available the shareholder list shall not affect the validity of any action taken at a meeting of shareholders of the Corporation.

Section 2.8 Quorum. Except as otherwise provided by law or by the Articles of Incorporation, the holders of a majority in voting power of the outstanding shares of capital stock of the Corporation entitled to vote thereat, present in person or represented by proxy, shall constitute a quorum for the transaction of business at all meetings of the shareholders of the Corporation. If a quorum is not present, the chairman of the meeting or the holders of a majority in voting power of the shares of capital stock of the Corporation present in person or represented by proxy at the meeting, and entitled to vote at the meeting, may adjourn the meeting to another place, if any, date and time. When a quorum is once present to commence a meeting of the shareholders of the Corporation, it is not broken by the subsequent withdrawal of any shareholders or their proxies.

Section 2.9 Adjournment and Postponement of Meetings.

(a) Any meeting of the shareholders of the Corporation, whether or not a quorum is present, may be adjourned to be reconvened at a specific date, time, place (if any) and/or by means of remote communication (if any) by the holders of a majority in voting power of the shares of capital stock present in person or represented by proxy at the meeting and entitled to vote at the meeting or, unless contrary to any provision of the Articles of Incorporation, these bylaws or applicable law, the Chairman of the Board of Directors or the Board of Directors. When a meeting of the shareholders of the Corporation is adjourned to another date, time, place (if any), and/or by means of remote communication (if any), notice need not be given of the adjourned meeting if the date, time and place (if any) thereof, and/or the means of remote communication (if any) by which shareholders and proxy holders may be deemed to be present in person and vote at such adjourned meeting, are announced at the meeting at which the adjournment is taken; provided, however, that if the adjournment is for more than thirty (30) days, a notice of the adjourned meeting shall be given to each shareholder of record entitled to vote at the meeting. If after the adjournment a new record date for determination of shareholders entitled to vote is fixed for the adjourned meeting, the Board of Directors shall fix as the record date for determining shareholders entitled to notice of such adjourned meeting the same or an earlier date as that fixed for determination of shareholders entitled to vote at the adjourned meeting, and shall give notice of the adjourned meeting to each shareholder of record as of the record date so fixed for notice of such adjourned meeting.

(b) Any previously scheduled meeting of the shareholders of the Corporation may be postponed, and (unless contrary to applicable law or the Articles of Incorporation) any special meeting of the shareholders may be cancelled, by resolution of the Board of Directors upon public announcement or notice given to the shareholders prior to the date previously scheduled for such meeting of shareholders.

(c) For purposes of these bylaws, 'public announcement' shall mean disclosure in a press release reported by the Dow Jones News Service, Associated Press, PR Newswire or comparable national news service or in a document publicly filed by the Corporation with the Securities and Exchange Commission pursuant to Section 13, 14 or 15(d) of the Securities Exchange Act of 1934, as amended (the 'Exchange Act'), and the rules and regulations promulgated thereunder.

Section 2.10 Vote Required. When a quorum is present, the affirmative vote of the majority in voting power of the shares of capital stock of the Corporation present in person or represented by proxy at the meeting and entitled to vote on the subject matter shall be the act of the shareholders of the Corporation, unless the question is one upon which, by express provisions of applicable law, the Articles of Incorporation, these bylaws, the rules or regulations of any stock exchange applicable to the Corporation, or pursuant to any regulation applicable to the Corporation or its securities, or the instrument of designation of any series of preferred stock of the Corporation, a different or additional vote is required or provided for, in which case such express provision shall govern and control the decision of such question. Where a separate vote by class or series is required or provided for, when a quorum is present, the affirmative vote of a majority in voting power of the shares of capital stock of the Corporation of such class or series present in person or represented by proxy at the meeting and entitled to vote on the subject matter shall be the act of such class or series of shareholders, unless the question is one upon which, by express provisions of applicable law, the Articles of Incorporation, these bylaws, the rules or regulations of any stock exchange applicable to the Corporation, or pursuant to any regulation applicable to the Corporation or its securities, or the instrument of designation of any series of preferred stock of the Corporation, a different or additional vote is required or provided for, in which case such express provision shall govern and control the decision of such question.

6

Section 2.11 Voting Rights. Except as otherwise provided by applicable law, each shareholder of the Corporation shall be entitled to that number of votes for each share of capital stock of the Corporation held by such shareholder as set forth in the Articles of Incorporation or, in the case of preferred stock of the Corporation, in the instrument of designation thereof.

Section 2.12 Proxies. Each shareholder entitled to vote at a meeting of shareholders of the Corporation may authorize another person or entity to act for such shareholder by proxy in such manner as prescribed under the VSCA, but no such proxy shall be voted or acted upon after three (3) years from its date unless such proxy expressly provides for a longer period. At each meeting of the shareholders of the Corporation, and before any voting commences, all proxies filed at or before the meeting shall be submitted to and examined by the Secretary or a person designated by the Secretary, and no shares may be represented or voted under a proxy that has been found (in the reasonable determination of the Secretary or such designee) to be invalid or irregular. Reference by the Secretary in the minutes of the meeting to the regularity of a proxy shall be received as prima facie evidence of the facts stated for the purpose of establishing the presence of a quorum at such meeting and for all other purposes. The revocability of a proxy that states on its face that it is irrevocable shall be governed by the applicable provisions of the VSCA and, without limiting the foregoing, a duly executed proxy shall be irrevocable if it states that it is irrevocable and if, and only so 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.

Section 2.13 Record Date.

(a) In order that the Corporation may determine the shareholders entitled to notice of any meeting of shareholders 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, unless otherwise required by law, not be more than sixty (60) nor less than ten (10) days before the date of such meeting. If the Board of Directors so fixes a date, such date shall also be the record date for determining the shareholders entitled to vote at such meeting unless the Board of Directors determines, at the time it fixes such record date, that a later date on or before the date of the meeting shall be the date for making such determination. If no record date is fixed by the Board of Directors, the record date for determining shareholders entitled to notice of or to vote at a meeting of shareholders shall be at the close of business on the day immediately preceding the day on which notice is given, or, if notice is waived, at the close of business on the day immediately preceding the day on which the meeting is held. A determination of shareholders of record entitled to notice of or to vote at a meeting of shareholders shall apply to any adjournment of the meeting; provided, however, that the Board of Directors may fix a new record date for determination of shareholders entitled to vote at the adjourned meeting, and in such case shall also fix as the record date for shareholders entitled to notice of such adjourned meeting the same or an earlier date as that fixed for determination of shareholders entitled to vote in accordance herewith at the adjourned meeting.

7

(b) In order that the Corporation may determine the shareholders entitled to receive payment of any dividend or other distribution or allotment of any rights, or entitled to exercise any rights in respect of any change, conversion or exchange of stock or for the purpose of any other lawful action, the Board of Directors may fix a record date, which record date shall not (i) precede the date upon which the resolution fixing the record date is adopted, or (ii) be more than sixty (60) days prior to such action. If no such record date is fixed, the record date for determining shareholders 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.

(c) Unless such action in writing without a meeting is otherwise restricted by the Articles of Incorporation, in order that the Corporation may determine the shareholders entitled to express consent to corporate action in writing without a meeting, 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 ten (10) days after the date upon which the resolution fixing the record date is adopted by the Board of Directors. Unless such action in writing without a meeting is otherwise restricted by the Articles of Incorporation, if no record date for determining shareholders entitled to express consent to corporate action in writing without a meeting is fixed by the Board of Directors, (i) when no prior action of the Board of Directors is required by law, the record date for such purpose 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 in accordance with applicable law, and (ii) if prior action by the Board of Directors is required by law, the record date for such purpose shall be at the close of business on the day on which the Board of Directors adopts the resolution taking such prior action.

Section 2.14 Advance Notice of Shareholder Business.

(a) Only such business shall be conducted before a meeting of the shareholders of the Corporation as shall have been properly brought before such meeting. To be properly brought before an annual or special meeting of the shareholders of the Corporation, business must be: (i) with respect to any annual meeting, (A) specified in the notice of meeting (or any supplement or amendment thereto) given by or at the direction of the Board of Directors or a duly authorized committee of the Board of Directors; (B) otherwise properly brought before the meeting by or at the direction of the Board of Directors or a duly authorized committee of the Board of Directors; or (C) otherwise properly brought before the meeting by any shareholder (1) who is a shareholder of record on the date of the giving of the notice provided for in this Section 2.14 and on the record date for the determination of shareholders entitled to vote at such annual meeting and (2) who complies with the notice procedures set forth in this Section 2.14; and (ii) with respect to any special meeting, specified in the notice of meeting (or any supplement or amendment thereto) given to the shareholders of the Corporation by the Board of Directors pursuant to and in accordance with Section 2.3.

(b) For such business to be considered properly brought before the meeting by a shareholder of the Corporation, such shareholder must, in addition to any other applicable requirements, have given timely notice thereof in proper written form to the Secretary. To be timely with respect to any annual meeting, a shareholder's notice to the Secretary must be delivered to or mailed and received by the Secretary at the principal executive office of the Corporation no fewer than ninety (90) and no more than one hundred twenty (120) days prior to the first (1st)

8

anniversary of the immediately preceding annual meeting of the shareholders of the Corporation; provided, however, that in the event that no annual meeting was held in the previous year or the annual meeting is called for a date that is not within thirty (30) days before or after such anniversary date, notice by the shareholder to be timely must be so received not later than the close of business on the tenth (10th) day following the day on which notice of the date of the annual meeting was mailed or public announcement of the date of the annual meeting was made, whichever occurs first. To be timely with respect to any special meeting, a shareholder's notice to the Secretary must be delivered or mailed and received by the Secretary at the principal executive office of the Corporation not less than sixty (60) days prior to the date of such meeting; provided, however, that in the event that less than seventy (70) days notice of the date of the meeting is given or made to shareholders, to be timely a shareholder's notice must be delivered or mailed and received by the Secretary at the principal executive office of the Corporation not later than the close of business on the tenth (10th) day following the earlier of the day on which such notice or public announcement of the date of such special meeting is mailed or made (as applicable) by the Corporation. In no event shall the public announcement of an adjournment or postponement of an announced meeting commence a new time period (or extend any time period) for the giving of a shareholders notice as provided in this Section 2.14.

(c) To be in proper written form, a shareholder's notice to the Secretary must set forth as to each matter such shareholder proposes to bring before the annual meeting: (i) a brief description of the business desired to be brought before the annual meeting and the reasons for conducting such business at the annual meeting; (ii) as to the shareholder giving the notice and the beneficial owner, if any, on whose behalf the proposal is made (A) the name and address of such shareholder, as they appear on the Corporation's books, and of such beneficial owner, (B) the class or series and number of shares of capital stock of the Corporation which are directly or indirectly (including through any derivative arrangement) owned (1) beneficially and (2) of record by such shareholder and by such beneficial owner, (C) a description of all arrangements or understandings between such shareholder or such beneficial owner and any other person or entity (including, without limitation, their names) in connection with the ownership of the capital stock of the Corporation and the proposal of such business by such shareholder and such beneficial owner, and any material interest (financial or otherwise) of such shareholder or such beneficial owner in such business, (D) whether either such shareholder or beneficial owner intends to deliver a form of proxy to holders of at least the percentage of the Corporation's voting shares required under applicable law to approve the proposal and (E) if the Corporation is then subject to Section 14(a) of the Exchange Act, any other information relating to such shareholder and beneficial owner, if any, required to be disclosed in a proxy statement or other filing required to be made in connection with a solicitation of proxies for the proposal pursuant to and in accordance with Section 14(a) of the Exchange Act and the rules and regulations promulgated thereunder; and (iii) a representation that such shareholder is a holder of record of stock of the Corporation entitled to vote at such meeting and intends to appear in person or by proxy at the meeting to introduce the business specified in the notice. As used herein, shares 'beneficially owned' by a person (and phrases of similar import) shall mean all shares which such person is deemed to beneficially own pursuant to Rules 13d-3 and 13d-5 under the Exchange Act, including, without limitation, shares which are beneficially owned, directly or indirectly, by any other person with which such person has any agreement, arrangement or understanding for the purpose of acquiring, holding, voting or disposing of any shares of the capital stock of the Corporation.

9

(d) The chairman of a meeting of the shareholders of the Corporation shall determine and declare at such meeting whether the shareholder proposal was made in accordance with the terms of this Section 2.14. If the chairman of the meeting determines that such proposal was not properly brought before the meeting in accordance with the foregoing procedures, the chairman of the meeting shall declare to the meeting that the proposal was not properly brought before the meeting and the business of such proposal shall not be transacted.

(e) This provision shall not prevent the consideration and approval or disapproval at any annual or special meeting of reports of officers, directors and committees of the Board of Directors, but in connection with such reports, no new business shall be acted upon at such meeting unless stated, filed and received as herein provided.

(f) In addition, notwithstanding anything in this Section 2.14 to the contrary, a shareholder of the Corporation intending to nominate one or more persons for election as a director at an annual or special meeting of shareholders must comply with Section 2.15 of these bylaws for such nomination to be properly brought before such meeting.

(g) For purposes of this Section 2.14, any adjournment(s) or postponement(s) of the original meeting whereby the meeting will reconvene within ninety (90) days from the original date shall be deemed for purposes of notice to be a continuation of the original meeting and no business may be brought before any such reconvened meeting unless pursuant to a notice of such business which was timely for the meeting and properly presented as determined as of the date originally scheduled.

Section 2.15 Advance Notice of Director Nominations.

(a) Unless otherwise required by applicable law or the Articles of Incorporation, only persons who are nominated in accordance with the following procedures shall be eligible for election as directors of the Corporation, except as may be otherwise provided in the instrument of designation of any series of preferred stock of the Corporation with respect to the right of holders of preferred stock of the Corporation to nominate and elect a specified number of directors of the Corporation, who shall be nominated as provided therein.

(b) Nominations of persons for election to the Board of Directors shall be made only at an annual or special meeting of shareholders of the Corporation called for the purpose of electing directors and must be (i) specified in the notice of meeting (or any supplement or amendment thereto) and (ii) made by (A) the Board of Directors or a duly authorized committee of the Board of Directors (or at the direction thereof) or (B) made by any shareholder of the Corporation (1) who is a shareholder of record on the date of the giving of the notice provided for in this Section 2.15 and on the record date for the determination of shareholders entitled to vote at such meeting and (2) who complies with the notice procedures set forth in this Section 2.15.

(c) In addition to any other applicable requirements, for a nomination to be made by a shareholder of the Corporation, such shareholder must have given timely notice thereof in proper written form to the Secretary. To be timely, a shareholder's notice to the Secretary must be delivered to or mailed and received at the principal executive office of the Corporation: (i) in the case of an annual meeting of the shareholders of the Corporation, no fewer than ninety (90)

10

nor more than one hundred twenty (120) days prior to the first (1st) anniversary of the immediately preceding annual meeting; provided, however, that in the event that no annual meeting was held in the previous year or the annual meeting is called for a date that is not within thirty (30) days before or after such anniversary date, notice by the shareholder to be timely must be so received not later than the close of business on the tenth (10th) day following the day on which notice of the date of the annual meeting was mailed or public announcement of the date of the annual meeting was made, whichever occurs first, and (ii) in the case of a special meeting of shareholders of the Corporation called for the purpose of electing directors, not less than sixty (60) days prior to the meeting; provided, however, that in the event that less than seventy (70) days notice of the date of the meeting is given or made to shareholders, notice by the shareholder to be timely must be so received not later than the close of business on the tenth (10th) day following the earlier of the day on which such notice or public announcement of the date of the meeting was mailed or made (as applicable). Notwithstanding anything to the contrary in the immediately preceding sentence, in the event that the number of directors to be elected to the Board of Directors is increased, a shareholder's notice required by this Section 2.15 shall also be considered timely, but only with respect to nominees for any new positions created by such increase and only if otherwise timely notice of nomination for all other directorships was delivered by such shareholder in accordance with the requirements of the immediately preceding sentence, if it shall be delivered to the Secretary at the principal executive office of the Corporation not later than the close of business on the tenth (10th) day following the day on which notice to the shareholders of the Corporation was given or public announcement was made by the Corporation naming all of the nominees for director or specifying the size of the increase in the number of directors to serve on the Board of Directors, even if such tenth (10th) day shall be later than the date for which a nomination would otherwise have been required to be delivered to be timely. In no event shall the public announcement of an adjournment or postponement of an announced meeting commence a new time period (or extend any time period) for the giving of a shareholders notice as provided in this Section 2.15.

(d) To be in proper written form, a shareholder's notice to the Secretary pursuant to this Section 2.15 must set forth (i) as to each person whom the shareholder of the Corporation proposes to nominate for election as a director, (A) the name, age, business address, and residence address of such person, (B) the principal occupation or employment of the person, (C) the class or series and number of shares of capital stock of the Corporation which are directly or indirectly (including through any derivative arrangement) owned beneficially or of record by the person, and (D) any other information relating to the person that would be required to be disclosed in a proxy statement or other filing required to be made in connection with a solicitation of proxies for an election of directors pursuant to the Exchange Act and the rules and regulations promulgated thereunder if the Corporation were a reporting company under the Exchange Act, and (ii) as to the shareholder giving the notice and the beneficial owner, if any, on whose behalf the director nomination is made (A) the name and address of such shareholder, as they appear on the Corporation's books, and of such beneficial owner; (B) the class or series and number of shares of capital stock of the Corporation which are owned (1) beneficially and (2) of record by such shareholder and by such beneficial owner, (C) a description of all arrangements or understandings between such shareholder or such beneficial owner and any other person or entity (including, without limitation, their names) in connection with the ownership of the capital stock of the Corporation and the nomination of such nominee(s), and any material interest of such shareholder or such beneficial owner in such nomination(s), (D) whether either such shareholder or beneficial

11

owner intends to deliver a form of proxy to holders of the Corporation's voting shares to elect such nominee or nominees, (E) a representation that the shareholder giving the notice is a holder of record of stock of the Corporation entitled to vote at such meeting and that such shareholder intends to appear in person or by proxy at the meeting to nominate the persons named in its notice and (F) if the Corporation is then subject to Section 14(a) of the Exchange Act, any other information relating to such shareholder and beneficial owner, if any, required to be disclosed in a proxy statement or other filing required to be made in connection with a solicitation of proxies for an election of directors pursuant to the Exchange Act and the rules and regulations promulgated thereunder. Such notice must be accompanied by a written consent of each proposed nominee to be named as a nominee and to serve as a director if elected. The Corporation may require any nominee to furnish such other information (which may include meeting to discuss the information) as may reasonably be required by the Corporation to determine the eligibility of such nominee to serve as a director of the Corporation.

(e) If the chairman of a meeting of the shareholders of the Corporation determines that a nomination was not made in accordance with the foregoing procedures, the chairman of the meeting shall declare to the meeting that the nomination was defective and such defective nomination shall be disregarded.

No officer, agent or employee shall have any power or authority to bind the Corporation by any contract or engagement or to pledge its credit or to render it liable for damages, whether monetary or otherwise, for any purpose or for any amount except as specifically authorized in these bylaws or by the Board of Directors or an officer or committee with the power to grant such authority.
