Section 2. Annual Meeting. The annual meeting of shareholders shall be held at 10:00 o’clock a.m. on the first Monday in May of each year, if not a legal holiday, but if a legal holiday, then on the next business day which is not a legal holiday, for the purpose of electing directors of the corporation and the transaction of such other business as may be properly brought before the meeting.

Section 3. Substitute Annual Meeting. If the annual meeting is not held on the day designated by these bylaws, a substitute annual meeting may be called in accordance with Section 4 of this Article. A meeting so called shall be designated and treated for all purposes as the annual meeting.

Section 4. Special Meetings. Special meetings of the shareholders may be called at any time by the board of directors, the chairman of the board, the vice chairman of the board, the president or the secretary, and must be called if the corporation has thirty-five (35) or fewer shareholders of record and the holders of at least twenty percent (20%) of all the votes entitled to be cast on any issue proposed to be considered at the proposed special meeting sign, date and deliver to the corporation’s secretary one or more written demands for the meeting describing the purpose or purposes for which it is to be held.

Section 5. Notice of Meetings. The corporation shall notify shareholders in writing of the date, time and place of each annual and special meeting of shareholders and, in the case of a special or substitute annual meeting or where otherwise required by law, shall briefly describe the purpose or purposes of the meeting. Such notice shall be given no less than ten (10) nor more than sixty (60) days before the meeting date except that notice of a meeting to act on an amendment of the articles incorporation, a plan of merger or share exchange, a proposed sale of all or substantially all of the assets of the corporation other than in the usual and regular course of business, or the dissolution of the corporation, shall be given no less than twenty-five (25) nor more than sixty (60) days before the meeting date. Only business within the purpose or purposes described in the notice may be conducted at a special meeting. Unless otherwise required by the articles of incorporation or by law (for example, in the event of a meeting to consider the adoption of a plan of merger or share exchange, a sale of assets other than in the ordinary course of business or a voluntary dissolution), the corporation shall be required to give notice only to shareholders entitled to vote at the meeting. If an annual or special shareholders’ meeting is adjourned to a different date, time or place, notice thereof need not be given if the new date, time or place is announced at the meeting before adjournment. If a new record date for the adjourned meeting is fixed pursuant to Article 7, Section 5 hereof, notice of the adjourned meeting shall be given to persons who are shareholders as of the new record date. It shall be the primary responsibility of the secretary to give the notice, but notice may be given by or at the direction of the president or other person or persons calling the meeting. If mailed, such notice shall be deemed to be effective when deposited in the United States mail with postage thereon prepaid, correctly addressed to the shareholder’s address shown in the corporation’s current record of shareholders.

Section 6. Quorum. Unless otherwise provided by the articles of incorporation or by law, a majority of the votes entitled to be cast by a voting group on a matter, represented in person or by proxy at a meeting of shareholders, shall constitute a quorum for that voting group for any action on that matter. Once a share is represented for any purpose at a meeting, it is deemed present for quorum purposes for the remainder of the meeting and any adjournment thereof, unless a new record date is or must be set for the adjournment. Action may be taken by a voting group at any meeting at which a quorum of that voting group is represented, regardless of whether action is taken at that meeting by any other voting group. In the absence of a quorum at the opening of any meeting of shareholders, such meeting may be adjourned from time to time by a vote of the majority of the shares voting on the motion to adjourn.

Section 7. Shareholders’ List for Meeting. The officer or agent having charge of the share transfer books of the corporation shall make, at least ten (10) days before each meeting of shareholders, a complete list of the shareholders entitled to vote at such meeting or any adjournment thereof, with the address of and the number of shares held by each. The list shall be arranged by voting group and within each voting group by class or series of shares. For a period of ten (10) days prior to the meeting, the list of shareholders shall be kept on file at the registered office of the corporation or at its principal office or at the office of its transfer agent or registrar and shall be subject to inspection by any shareholder at any time during usual business hours. Such list shall also be produced and kept open at the time and place of the meeting and shall be subject to the inspection of any shareholder during the whole time of the meeting for the

2

purposes thereof. The original share transfer books shall be prima facie evidence as to who are the shareholders entitled to examine such list or transfer books or to vote at any meeting of shareholders. If the requirements of this Section 7 have not been substantially complied with, the meeting shall, on the demand of any shareholder in person or by proxy, be adjourned until the requirements are complied with. Refusal or failure to prepare or make available the shareholders’ list does not affect the validity of action taken at the meeting prior to the making of any such demand, but any action taken by the shareholders after the making of any such demand shall be invalid and of no effect.

Section 8. Voting of Shares. Except as otherwise provided by the articles of incorporation or by law, each outstanding share of voting capital stock of the corporation shall be entitled to one vote on each matter submitted to a vote at a meeting of the shareholders. Unless otherwise provided in the articles of incorporation, cumulative voting for directors shall not be allowed. Action on a matter by a voting group for which a quorum is present is approved if the votes cast within the voting group favoring the action exceed the votes cast opposing the action, unless the vote of a greater number is required by law or by the articles of incorporation. Voting on all matters shall be by voice vote or by a show of hands, unless the holders of one-tenth of the shares represented at the meeting shall demand a ballot vote on a particular matter. The shares of the corporation are not entitled to vote if they are owned, directly or indirectly, by a second corporation, domestic or foreign, and the corporation owns, directly or indirectly, a majority of the shares entitled to vote for directors of the second corporation.

Section 9. Inspectors of Election.

(a) Appointment of Inspectors of Election. In advance of any meeting of shareholders, the board of directors may appoint any persons, other than nominees for office, as inspectors of election to act at such meeting or any adjournment thereof. If inspectors of election are not so appointed, the chairman of any such meeting may, and on the request of any shareholder or his proxy shall, appoint inspectors of election at the meeting. The number of inspectors shall be either one or three. If appointed at a meeting on the request of one or more shareholders or proxies, the majority of shares present shall determine whether one or three inspectors are to be appointed. In case any person appointed as inspector fails to appear or fails or refuses to act, the vacancy may be filled by appointment by the board of directors in advance of the meeting, or at the meeting by the person acting as chairman.

(b) Duties of inspectors. The inspectors of election shall determine the number of shares outstanding and the voting power of each, the shares represented at the meeting, the existence of a quorum, the authenticity, validity, and effect of proxies, receive votes, ballots, or consents, hear and determine all challenges and questions in any way arising in connection with the right to vote, count and tabulate all votes or consents, determine the result, and do such acts as may be proper to conduct the election or vote with fairness to all shareholders. The inspectors of election shall perform their duties impartially, in good faith, to the best of their ability and as expeditiously as is practical.

3

(c) Vote of inspectors. If there are three inspectors of election the decision, act, or certificate of a majority is effective in all respects as the decision, act, or certificate of all.

(d) Report of inspectors. On request of the chairman of the meeting or of any shareholder or his proxy the inspectors shall make a report in writing of any challenge or question or matter determined by them and execute a certificate of any fact found by them. Any report or certificate made by them is prima facie evidence of the facts stated herein.

Section 10. Action Without Meeting. Any action which the shareholders could take at a meeting may be taken without a meeting if one or more written consents, setting forth the action taken, shall be signed by all the shareholders who would be entitled to vote upon the action at a meeting. The consent shall be delivered to the corporation for inclusion in the minutes or filing with the corporate records. Any action taken by unanimous written consent shall be effective according to its terms when all consents are in the possession of the corporation. A shareholder may withdraw consent only by delivering a written notice of withdrawal to the corporation prior to the time that all consents are in the possession of the corporation. Action taken without a meeting is effective as of the date specified therein, provided the consent states the date of execution by each shareholder. If by law, the corporation is required to give its nonvoting shareholders written notice of the proposed action, it shall do so at least 10 days before the action is taken, and such notice must contain or be accompanied by the same material that would have been required by law to be sent to nonvoting shareholders in a notice of meeting at which the proposed action would have been submitted to the shareholders for action.

Section 11. Actions to be Taken at Annual Meetings of Shareholders. No business shall be transacted at an annual meeting of shareholders, except business that is (a) specified in the notice of meeting given as provided in Section 5 of this Article, (b) otherwise brought before the meeting by or at the direction of the board of directors, or (c) otherwise brought before the meeting by a shareholder of record of the corporation entitled to vote at the meeting, in compliance with the procedures set forth in this Section 11. For business to be brought before an annual meeting by a shareholder pursuant to clause (c) above, the shareholder must give timely notice in writing to the secretary. To be timely, the notice must be delivered to, or mailed and received at, the principal office of the corporation not less than sixty (60) days nor more than ninety (90) days prior to the meeting; provided, however, that in the event that less than seventy (70) days’ notice or prior public disclosure 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 10th day following the day on which the notice of the date of the meeting or such public disclosure was made. Notice of actions brought before the annual meeting pursuant to clause (c) above shall set forth as to each matter the shareholder proposes to bring before the annual meeting (1) a brief description of the business desired to be brought before the annual meeting and the reasons therefor and (2) the name and address, as they appear on the corporation’s books, of the shareholder giving the notice; the classes and number of shares of the corporation owned of record or beneficially by the shareholder; and any material interest of the shareholder in the proposed business other than his interest as a shareholder of the corporation. Notwithstanding anything in these bylaws to the contrary, no business shall be

4

conducted at an annual meeting except in accordance with the provisions set forth in this Section. The chairman of the meeting shall, if the facts warrant, determine and declare to the meeting whether business was not properly brought before the meeting in accordance with the provisions prescribed by these bylaws and, if the chairman should so determine, the chairman shall so declare to the meeting that, to the extent permitted by law, any business not properly brought before the meeting shall not be transacted.

Section 2. Number, Term and Qualification. The number of directors of the corporation shall be not less than five nor more than twelve individuals. The number of directors shall be fixed from time to time by a resolution of the majority of the board of directors or by a resolution of the shareholders at any meeting; but in the absence of such resolution, the number of directors elected at the meeting shall constitute the number of directors of the corporation until the next annual meeting of the shareholders, unless the number is changed prior to such meeting in the manner set forth above. In the absence of such resolution, the number of directors elected at the meeting shall constitute the number of directors of the corporation until the next annual meeting of shareholders, unless the number is changed prior to such meeting by action of the shareholders. Each director’s term shall expire at the annual meeting next following the director’s election as a director, provided, that notwithstanding the expiration of the term of the director, the director shall continue to hold office until a successor is elected and qualifies or until his death, resignation, removal or disqualification or until there is a decrease in the number of directors. The term of a director elected to fill a vacancy expires at the next annual meeting of shareholders. Directors need not be residents of the states of Virginia or North Carolina or shareholders of the corporation unless the articles of incorporation so provide.

Section 3. Removal. Directors may be removed from office with or without cause (unless the articles of incorporation provide that directors may be removed only with cause) provided the notice of the shareholders’ meeting at which such action is to be taken states that a purpose of the meeting is removal of the director and the number of votes cast to remove the director constitutes a majority of the votes entitled to be cast at an election of directors of the voting group or voting groups by which the director was elected.

Section 4. Vacancies. Except as otherwise provided in the articles of incorporation, a vacancy occurring in the board of directors, including, without limitation, a vacancy resulting from an increase in the number of directors, may be filled by a majority of the directors remaining in office. The shareholders may elect a director at any time to fill a vacancy not filled by the directors. A director elected to fill a vacancy shall be elected for the unexpired term of his predecessor in office.

Section 5. Compensation. The directors shall not receive compensation for their services as such, except that by resolution of the board of directors, the directors may be paid fees, which may include but are not restricted to fees for attendance at meetings of the board or of a committee, and they may be reimbursed for expenses of attendance. Any director may serve the corporation in any other capacity and receive compensation therefor.

Section 6. Nominations for Election of Directors. Only persons who are nominated in accordance with the provisions set forth in these bylaws shall be eligible to be elected as directors at an annual or special meeting of shareholders. Nominations of persons for election to the board of directors may be made at such meeting of shareholders (a) by or at the direction of the board of directors, and (b) by any shareholder of the corporation who is a shareholder of record at the time of giving of notice provided for in this Section, who shall be entitled to vote for the election of directors at the meeting and who complies with the notice procedure set forth in this Section. Such nominations other than those made by or at the direction of the board of directors, shall be made pursuant to timely notice in writing to the secretary. To be timely, a shareholders’ notice must be delivered to or mailed and received at the principal office of the corporation not less than sixty (60) days nor more than ninety (90) days prior to the meeting; provided, however, that in the event that less than seventy (70) days’ notice or prior public disclosure 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 10th day following the day on which such notice of the date of the meeting or such public disclosure was made. Notice shall be deemed to have been given more than seventy (70) days in advance of the annual meeting if the annual meeting is called in accordance with Article 2, Section 2 hereof without regard to when public disclosure of such meeting is made. The shareholder’s notice shall set forth (a) as to each person whom the shareholder proposes to nominate for election or reelection as a director, information relating to such persons similar in substance to that required to be disclosed in solicitations of proxies for election of directors pursuant to Items 7(a) and (b) of Regulation 14A under the Securities Exchange Act of 1934, as amended, and such person’s written consent to being named as a nominee and to serving as a director if elected, and (b) as to the shareholder giving the notice (i) the name and address, as they appear on the corporation’s books, of such shareholder and (ii) the class and number of shares of the corporation which are owned of record or beneficially by such shareholder. 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 that information required to be set forth in a shareholder’s notice of nomination which pertains to the nominee. 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 provisions prescribed by these bylaws and, if he should so determine, he shall so declare to the meeting that the defective nomination shall be disregarded.

Action taken without a meeting is effective when the last director signs the consent, unless the consent specifies a different effective date.

Except as otherwise provided by law, no transfer of shares shall be valid as against the corporation, its shareholders or creditors, for any purpose, until it shall have been entered in the stock transfer records of the corporation by an entry showing from and to whom transferred.

Section 3. Transfer Agent and Registrar. The board of directors may appoint one or more transfer agents and one or more registrars of transfers and may require all stock certificates to be signed or countersigned by the transfer agent and registered by the registrar of transfers.

Section 4. Regulations. The board of directors may make rules and regulations as it deems expedient concerning the issue, transfer and registration of shares of capital stock of the corporation.

Section 5. Fixing Record Date. For the purpose of determining shareholders entitled to notice of or to vote at any meeting of shareholders, or entitled to receive payment of any dividend, or in order to make a determination of shareholders for any other purpose, the board of directors may fix in advance a date as the record date for the determination of shareholders. The record date shall be not more than seventy (70) days before the meeting or action requiring a determination of shareholders. A determination of shareholders entitled to notice of or to vote at a shareholders’ meeting shall be effective for any adjournment of the meeting unless the board of directors fixes a new record date, which it shall do if the meeting is adjourned to a date more than one hundred twenty (120) days after the date fixed for the original meeting. If no record date is fixed for the determination of shareholders, the record date shall be the day the notice of the meeting is mailed or the day the action requiring a determination of shareholders is taken. If no record date is fixed for action without a meeting, the record date for determining shareholders entitled to take action without a meeting shall be the date the first shareholder signs a consent to the action taken.

Section 6. Lost Certificates. The board of directors may direct a new certificate or certificates to be issued in place of any lost or destroyed certificate or certificates previously issued by the corporation if the person or persons who claim the certificate or certificates make an affidavit stating that the certificates of stock have been lost or destroyed. When authorizing the issuance 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 or destroyed certificate or certificates, or the legal representative, to advertise the same in such manner as the board of directors shall require and/or to give the corporation a bond or other form of indemnification, in such sum as the board of directors may direct, to indemnify the corporation against any claim that may be made against the corporation with respect to the certificate or certificates alleged to have been lost or destroyed.

ARTICLE 8 — INDEMNIFICATION OF DIRECTORS AND OFFICERS

Section 1. Indemnification Provisions. Any person who at any time serves or has served as a director or officer of the corporation or of any wholly owned subsidiary of the corporation, or in such capacity at the request of the corporation for any other foreign or domestic corporation, partnership, joint venture, trust or other enterprise, or as a trustee or administrator under any employee benefit plan of the corporation or of any wholly owned subsidiary thereof (a “Claimant”), shall have the right to be indemnified and held harmless by the corporation to the

13

fullest extent from time to time permitted by law against all liabilities and litigation expenses (as hereinafter defined) in the event a claim shall be made or threatened against that person in, or that person is made or threatened to be made a party to, any threatened, pending or completed action, suit or proceeding, whether civil, criminal, administrative or investigative, and whether or not brought by or on behalf of the corporation, including all appeals therefrom (a “proceeding”), arising out of such service; provided, that such indemnification shall not be effective with respect to (a) that portion of any liabilities or litigation expenses with respect to which the Claimant is entitled to receive payment under any insurance policy or (b) any liabilities or litigation expenses incurred on account of any of the Claimant’s activities which were at the time taken known or believed by the Claimant to be clearly in conflict with the best interests of the corporation.

Section 2. Definitions. As used in this Article, (a) “liabilities” shall include, without limitation, (1) payments in satisfaction of any judgment, money decree, excise tax, fine or penalty for which Claimant had become liable in any proceeding and (2) payments in settlement of any such proceeding subject, however, to Section 3 of this Article 8; (b) “litigation expenses” shall include, without limitation, (1) reasonable costs and expenses and attorneys’ fees and expenses actually incurred by the Claimant in connection with any proceeding and (2) reasonable costs and expenses and attorneys’ fees and expenses in connection with the enforcement of rights to the indemnification granted hereby or by applicable law, if such enforcement is successful in whole or in part; and (c) “disinterested directors” shall mean directors who are not party to the proceeding in question.

Section 3. Settlements. The corporation shall not be liable to indemnify the Claimant for any amounts paid in settlement of any proceeding effected without the corporation’s written consent. The corporation will not unreasonably withhold its consent to any proposed settlement.

Section 4. Litigation Expense Advances.

(a) Except as provided in subsection (b) below, any litigation expenses shall be advanced to any Claimant within 30 days of receipt by the secretary of the corporation of a demand therefor, together with an undertaking by or on behalf of the Claimant to repay to the corporation such amount unless it is ultimately determined that the Claimant is entitled to be indemnified by the corporation against such expenses. The secretary shall promptly forward notice of the demand and undertaking immediately to all directors of the corporation.

(b) Within 10 days after mailing of notice to the directors pursuant to subsection (a) above, any disinterested director may, if desired, call a meeting of all disinterested directors to review the reasonableness of the expenses so requested. No advance shall be made if a majority of the disinterested directors affirmatively determines that the item of expense is unreasonable in amount; but if the disinterested directors determine that a portion of the expense item is reasonable, the corporation shall advance such portion.

Section 5. Approval of Indemnification Payments. Except as provided in Section 4 of this Article, the board of directors of the corporation shall take all such action as

14

may be necessary and appropriate to authorize the corporation to pay the indemnification required by Section 1 of this Article, including, without limitation, making a good faith evaluation of the manner in which the Claimant acted and of the reasonable amount of indemnity due the Claimant. In taking any such action, any Claimant who is a director of the corporation shall not be entitled to vote on any matter concerning such Claimant’s right to indemnification.

Section 6. Suits by Claimant. No Claimant shall be entitled to bring suit against the corporation to enforce his rights under this Article until sixty days after a written claim has been received by the corporation, together with any undertaking to repay as required by Section 4 of this Article. It shall be a defense to any such action that the Claimant’s liabilities or litigation expenses were incurred on account of activities described in clause (b) of Section 1, but the burden of proving this defense shall be on the corporation. Neither the failure of the corporation to determine that indemnification of the Claimant is proper, nor determination by the corporation that indemnification is not due because of application of clause (b) of Section 1 shall be a defense to the action or create a presumption that the Claimant has not met the applicable standard of conduct.

Section 7. Consideration; Personal Representatives and Other Remedies. Any Claimant who during such time as this Article or corresponding provisions of predecessor bylaws is or has been in effect serves or has served in any of the capacities described in Section 1 shall be deemed to be doing so or to have done so in reliance upon, and as consideration for, the right of indemnification provided herein or therein. The right of indemnification provided herein or therein shall inure to the benefit of the legal representatives of any Claimant hereunder, and the right shall not be exclusive of any other rights to which the Claimant or legal representative may be entitled apart from this Article.

Section 8. Scope of Indemnification Rights. The rights granted herein shall not be limited by the provisions of Section 13.1-697 of the Virginia Stock Corporation Act or any successor statute.

Section 3. Waiver of Notice. Whenever notice is required to be given to a shareholder, director or other person under the provisions of these bylaws, the articles of incorporation or applicable law, a waiver in writing signed by the person or persons entitled to

15

the notice, whether before or after the date and time stated in the notice, and delivered to the corporation shall be equivalent to giving the notice.

Section 6. Amendments.

These bylaws may be amended or repealed by the shareholders even though the bylaws may also be amended or repealed by the board of directors. A bylaw that fixes a greater quorum or voting requirement for the board of directors may be amended or repealed (a) if originally adopted by the shareholders, only by the shareholders or (b) if originally adopted by the board of directors, either by the shareholders or by the board of directors, provided that if the bylaw being amended or repealed by the board of directors changes the quorum or voting requirement applicable to meetings of the board of directors, the quorum and voting requirements currently in effect must be met. A bylaw adopted or amended by the shareholders that fixes a greater quorum or voting requirement for the board of directors may provide that it may be amended or repealed only by a specified vote of either the shareholders or the board of directors.

Section 7. Shareholders’ Agreement. In the event of a conflict between these bylaws and a valid shareholders’ agreement, the shareholders’ agreement shall control.
