ARTICLE III

Board of Directors

Section 1 - General Powers - The affairs of the Corporation shall be managed by its Board of Directors.

Section 2 – Number and Term - The number of directors of the Corporation shall be within the range established by the Articles of Incorporation of the Corporation and may be fixed from time to time by an amendment to these Bylaws or by a resolution adopted by the Board of Directors.

The directors shall be divided into three classes (A, B and C) as nearly equal in number as possible. The initial term of office for members of Class A shall expire at the annual meeting of Stockholders in 1997; the initial term of office for members of Class B shall expire at the annual meeting of Stockholders in 1998; and the initial term of office for members of Class C shall expire at the annual meeting of Stockholders in 1999. At each annual meeting of Stockholders following such initial classification and election, directors elected to succeed those directors whose terms expire after their election shall continue to hold office until their respective successors are elected and qualified.

Section 3 - Vacancies and Removal - Any vacancy occurring in the Board, including a vacancy resulting from the removal of a director or an increase in the number of directors, may be filled by (i) the Stockholders, (ii) the Board of Directors, or (iii) the affirmative vote of a majority of the remaining directors though less than a quorum of the Board of Directors, and may, in the case of a resignation that will become effective at a specified later date, be filled before the vacancy occurs but the new director may not take office until the vacancy occurs.

The Stockholders may remove one or more directors, with or without cause. If a director is elected by a voting group, only Stockholders of that voting group may elect to remove such director. Unless the Articles of Incorporation require a greater vote, a director may be removed if the number of votes cast to remove the director constitutes a majority of the votes entitled to be cast at an election of directors by the voting group or voting groups by which such director was elected. A director may be removed by the Stockholders only at a meeting called for the purpose of removing him and the meeting notice must state that the purpose, or one of the purposes of the meeting, is removal of the director.

Section 4 - Annual and Regular Meetings - An annual meeting of the Board of Directors, which shall be considered a regular meeting, shall be held immediately following each annual meeting of Stockholders, for the purpose of electing officers and carrying on such other business as may come before the meeting. The Board of Directors may also adopt a schedule of additional meetings which shall be considered regular meetings. Regular meetings shall be held at such times and such places, within or without the Commonwealth of Virginia, as the Chairman, the President or the Board of Directors shall designate from time to time. If no place is designated, regular meetings shall be held at the principal office of Roanoke Electric Steel Corporation in Roanoke, Virginia.

Section 5 - Special Meetings - Special meetings of the Board of Directors may be called by the Chairman, the President, or one-third in number of the directors then in office, and shall be held at such times and at such places, within or without the Commonwealth of Virginia, as the person or persons calling the meetings shall designate. If no place is designated, it shall be held at the principal office of Roanoke Electric Steel Corporation in Roanoke, Virginia.

Section 6 - Notice of Meetings - No notice need be given of regular meetings of the Board of Directors.

Notices of special meetings of the Board of Directors shall be given to each director in person or delivered to his residence or business address (or such other place as he may direct in writing) not less than twenty-four (24) hours before the meeting by mail, messenger, electronic

transmission (as defined in Section 13.1-603 of the Virginia Stock Corporation Act) consented to by the director as contemplated by Section 13.1-686C of the Virginia Stock Corporation Act, or other means of written communication, or by telephoning such notice to him. Any such notice shall set forth the time and place of the meeting.

Section 7 - Waiver of Notice; Attendance at Meeting - A director may waive any notice required by law, the Articles of Incorporation, or these Bylaws before or after the date and time stated in the notice, and such waiver shall be equivalent to the giving of such notice. Except as provided in the next paragraph of this section, the waiver shall be in writing, signed by the director entitled to the notice and filed with the minutes or the corporate records.

A director’s attendance at or participation in a meeting waives any required notice to him of the meeting unless the director at the beginning of the meeting or promptly upon his arrival objects to holding the meeting or transacting business at the meeting and does not thereafter vote for or assent to action taken at the meeting.

Section 8 - Quorum; Manner of Acting - A majority of the number of directors fixed by or in accordance with these Bylaws shall constitute a quorum for the transaction of business at a meeting of the Board of Directors. If a quorum is present when a vote is taken, the affirmative vote of a majority of the directors present is the act of the Board of Directors. A director who is present at a meeting of the Board of Directors or a committee of the Board of Directors when corporate action is taken is deemed to have assented to the action taken unless (i) the director objects, at the beginning of the meeting, or promptly upon his arrival, to holding it or transacting specified business at the meeting, or (ii) he votes against, or abstains from, the action taken.

Section 9 - Acting Without a Meeting - Any action required or permitted to be taken at a meeting of the Board of Directors may be taken without a meeting if the action is taken by all of the members of the Board. The action shall be evidenced by one or more written consents stating the action taken, signed by each director either before or after the action taken, and included in the minutes or filed with the corporate records reflecting the action taken. Action taken under this section shall be effective when the last director signs the consent unless the consent specifies a different effective date, in which event the action taken is effective as of the date specified therein provided the consent states the date of execution by the director.

Section 10 - Telephonic Meetings - The Board of Directors may permit any or all directors to participate in a regular or special meeting by, or conduct the meeting through the use of, any means of communication by which all directors participating may simultaneously hear each other during the meeting. A director participating in a meeting by this means is deemed to be present in person at the meeting.

The creation of a committee and appointment of members to it shall be approved by the greater of (i) a majority of all directors in office when the action is taken, or (ii) the number of directors required by the Articles of Incorporation or these Bylaws to take action.

To the extent specified by the Board of Directors, each committee may exercise the authority of the Board of Directors (with the Executive Committee being authorized to exercise all such authority except as limited by the provisions of this section of these Bylaws), except that a committee (including the Executive Committee) may not (i) approve or recommend to Stockholders action that is required by law to be approved by Stockholders, (ii) fill vacancies on the Board of Directors or on any of its committees, (iii) amend the Articles of Incorporation, (iv) adopt, amend or repeal these Bylaws, (v) approve a plan of merger not requiring Stockholder approval, (vi) authorize or approve a distribution, except according to a general formula or method prescribed by the Board of Directors, or (vii) authorize or approve the issuance or sale or contract for sale of shares, or determine the designation and relative rights, preferences, and limitations of a class or series of shares, except that (in the case of this item (vii)) the Board of Directors may authorize a committee, or senior executive officer of the Corporation, to do so within limits specifically prescribed by the Board of Directors.

The provisions of these Bylaws which govern the meetings, action without meetings, notice, waiver of notice, and quorum and voting requirements of the Board of Directors shall apply to committees of directors and their members as well; provided, however, that, with respect to notice of special meetings of committees, notice shall be given not less than twelve (12) hours before the meeting.
