ARTICLE 5. PARTICIPATION

Each Non-Employee Director shall be eligible to receive Restricted Stock Awards as described below in Article 6 during his or her tenure as a Non-Employee Director.

ARTICLE 6. FORMULA GRANTS OF RESTRICTED STOCK

6.1 Formula Grants of Restricted Stock. Subject to the terms of the Plan, Restricted Stock shall be granted to Non-Employee Directors automatically and without further action of the Board of Directors as follows:

(a) Annual Grants. On the first business day following each annual meeting of the Company’s stockholders beginning with the 2005 Annual Meeting of Stockholders, each Non-Employee Director who is then a member of the Board shall receive a grant of Restricted Stock consisting of that number of shares that equals $60,000 divided by the Average Market Value of the Common Stock as of the Grant Date, rounded up to the nearest whole share. The Restricted Stock shall vest in full on the earlier of (i) the first anniversary of the Grant Date or (ii) the day before the next annual meeting of the Company’s stockholders following the Grant Date. Vesting on any such date is subject to continued service as a Director (whether or not in the capacity of a Non-Employee Director) through such date.

(b) Interim Grants to New Non-Employee Directors. If a Non-Employee Director initially becomes a member of the Board during a calendar year but after the annual meeting of the Company’s stockholders has been held for such year, the Non-Employee Director shall receive a grant of Restricted Stock, effective as of the date of such initial appointment to the Board, consisting of that number of shares that equals $60,000 divided by the Average Market Value of the Common Stock as of the Grant Date, rounded up to the nearest whole share. The shares covered by such grant of Restricted Stock shall vest in full on the first anniversary of the Grant Date. Vesting on such date is subject to continued service as a Director (whether or not in the capacity of a Non-Employee Director) through such date.

6.2 Nontransferability. The shares of Restricted Stock may not be sold, assigned, conveyed, pledged, exchanged, hypothecated, alienated or otherwise disposed of or transferred in any manner to the extent they remain unvested.

6.3 Termination of Service. In the event that a Director’s service on the Board terminates for any reason, all shares of Restricted Stock not vested at the time of such termination shall be immediately and automatically forfeited by such Director.

6.4 Change in Control. Notwithstanding any other provision of the Plan, all outstanding shares of Restricted Stock shall be deemed vested as of (a) the date of consummation of a tender offer or exchange offer that constitutes a Change in Control or (b) the third business day prior to the effective date of any other Change in Control.

6.5 Stockholder Rights. Except as otherwise provided by the Plan, a Non-Employee Director who has been granted Restricted Stock shall have the rights and privileges of a stockholder as to such Restricted Stock, including the right to vote such Restricted Stock and the right to receive dividends, if and when declared by the Board of Directors. With respect to any shares of Restricted Stock received as a result of adjustments under Section 4.2 hereof and also any shares of Common Stock that result from dividends declared on the Common Stock, the Non-Employee Director shall have the same rights and privileges, and be subject to the same restrictions, as apply generally to Restricted Stock under the Plan.

6.6 Award Agreement. Each grant of Restricted Stock shall be evidenced by an award agreement executed by the Non-Employee Director and the Company that contains the Grant Date of the Restricted Stock and the other terms and conditions applicable thereto.

6.7 Issuance of Restricted Stock/Stock Certificates. A grant of Restricted Stock may be evidenced in such manner as the Company shall deem appropriate, including without limitation, book-entry registration or the issuance of a stock certificate (or certificates) representing the number of shares of Restricted Stock granted to the Non-Employee Director, containing such legends as the Company deems appropriate and held in custody by the Company or on its behalf, in which case the grant of Restricted Stock shall be accompanied by appropriate stop-transfer instructions to the transfer agent for the Common Stock, until the restrictions lapse and the shares of Restricted Stock become vested. The Company may require the Director to deliver to the Company a stock power, endorsed in blank, relating to the shares of Restricted Stock to be held in custody by or for the Company.

ARTICLE 7. AMENDMENT, SUSPENSION AND TERMINATION

The Board may at any time, and from time to time, amend, suspend or terminate the Plan in whole or in part; provided, that no amendment, suspension or termination shall be effective unless approved by the stockholders of the Company (a) to the extent stockholder approval is necessary to satisfy the applicable requirements of the Exchange Act or Rule 16b-3 thereunder, any New York Stock Exchange, Nasdaq or securities exchange listing requirements or any other law or regulation; or (b) to the extent the Board determines, in its discretion, that stockholder approval is desirable even if such stockholder approval is not expressly required by the Plan or applicable law or regulation. Unless sooner terminated by the Board, the Plan shall terminate ten years from the date the Plan is adopted by the Board. No further Restricted Stock Awards may be granted after the termination of the Plan, but the Plan shall remain effective with respect to any then outstanding Restricted Stock Awards. Except as otherwise provided herein, no amendment, suspension or termination of the Plan shall adversely affect in any material way the rights of a Non-Employee Director under any outstanding Restricted Stock Award without the Non-Employee Director’s consent. Notwithstanding the foregoing, it is expressly contemplated that the Board may amend the Plan or the terms of any outstanding Restricted Stock Award in any respect it deems necessary or advisable to comply with applicable law, including, but not limited to, Section 409A of the Code and applicable guidance thereunder, without obtaining the individual consent of any Non-Employee Director who holds an outstanding Restricted Stock Award.

ARTICLE 8. TAX MATTERS

8.1 Withholding. To the extent applicable, a Director that has received a Restricted Stock Award under this Plan shall pay or make provision for payment to the Company the amount necessary to satisfy any federal, state or local withholding requirements applicable to any taxable event arising in connection with the Restricted Stock Award. The determination of the withholding amounts due in such event shall be made by the Company and shall be binding upon the Director. The Company shall not be required to deliver any shares of Common Stock unless the Director has made acceptable arrangements to satisfy any such withholding requirements. Notwithstanding the foregoing, nothing in this Section shall be construed to impose on the Company a duty to withhold where applicable law does not require such withholding.

8.2 Section 83(b) Election. If a Non-Employee Director makes an election pursuant to Section 83(b) of the Code with respect to Restricted Stock, the Non-Employee Director shall be required to promptly file a copy of such election with the Company as required under Section 83(b) of the Code.

ARTICLE 9. GENERAL PROVISIONS

9.1 Restrictions on Stock Ownership/Legends. The Board, in its discretion, may establish guidelines applicable to the ownership of any shares of Common Stock acquired under this Plan as it may deem desirable or advisable, including, but not limited to, time-based or other restrictions on transferability regardless of whether or not the Common Stock is otherwise vested. All stock certificates representing shares of Common Stock issued pursuant to this Plan shall be subject to such stock transfer orders and other restrictions as the Board may deem advisable and the Board may cause any such certificates to have legends affixed thereto to make appropriate references to any applicable restrictions.

9.2 No Guarantee of Continued or Future Service on the Board. Nothing in the Plan or any award agreement shall be construed to confer upon any Director any right to continued or future service on the Board of Directors.

9.3 Unfunded Plan. To the extent that any person acquires a right to receive Common Stock under the Plan, such right shall be only contractual in nature unsecured by any assets of the Company or a Subsidiary. Neither the Company nor any Subsidiary shall be required to segregate any specific funds, assets or other property with respect to any Restricted Stock Awards under this Plan. With respect to receipt of Common Stock, a Director (and any person claiming through him) shall have only the status of an unsecured general creditor of the Company.

9.4 Requirements of Law. The granting of Restricted Stock Awards under the Plan shall be subject to all applicable laws, rules and regulations, and to such approvals by any governmental agencies or national securities exchanges as may be required. To the extent applicable, the Plan is intended to comply with all provisions of Rule 16b-3 or any successor rule under the Exchange Act, unless determined otherwise by the Board.

9.5 Approvals and Listing. The Company shall not be required to grant any Restricted Stock Awards or issue any certificate or certificates for shares of Common Stock under the Plan prior to (a) obtaining any required approval from the stockholders of the Company; (b) obtaining any approval from any governmental agency which the Company shall, in its discretion, determine to be necessary or advisable; (c) the admission of such shares of Common Stock to listing on any national securities exchange on which the Company’s Common Stock may be listed; and (d) the completion of any registration or other qualification of such shares of Common Stock under any state or federal law or ruling or regulation of any governmental body which the Company shall, in its sole discretion, determine to be necessary or advisable. The Company may require that any Non-Employee Director granted a Restricted Stock Award hereunder make such representations and agreements and furnish such information as it deems appropriate to assure compliance with the foregoing or any other applicable legal requirement. Notwithstanding the foregoing, the Company shall not be obligated at any time to file or maintain a registration statement under the Securities Act of 1933, as amended, or to effect similar compliance under any applicable state laws with respect to the Common Stock that may be issued pursuant to this Plan.

9.6 Other Corporate Actions. Nothing contained in the Plan shall be construed to limit the authority of the Company to exercise its corporate rights and powers, including, but not by way of limitation, the right of the Company to adopt other compensation arrangements or the right of the Company to authorize any adjustment, reclassification, reorganization, or other change in its capital or business structure, any merger or consolidation of the Company, the dissolution or liquidation of the Company, or any sale or transfer of all or any part of its business or assets.

9.7 Gender and Number. Except where otherwise indicated by the context, any masculine term used herein shall also include the feminine, and the plural shall include the singular and the singular shall include the plural.

9.8 Severability. The invalidity or unenforceability of any particular provision of this Plan shall not affect the other provisions hereof, and the Board may elect in its discretion to construe such invalid or unenforceable provision in a manner which conforms to applicable law or as if such provision was omitted.

9.9 Governing Law. To the extent not preempted by federal law, the Plan, and all award agreements hereunder, shall be construed in accordance with and governed by the laws of the State of North Carolina (excluding the principles of conflict of law thereof).
