ARTICLE ONE: OFFICES

1.01 Registered Office and Agent. The registered office and registered agent of Lufkin Industries, Inc. (the “Corporation”) shall be as designated from time to time by the appropriate filing by the Corporation in the office of the Secretary of State of Texas.

1.02 Other Offices. The Corporation may also have offices at such other places, both within and without the State of Texas, as the board of directors may from time to time determine or the business of the Corporation may require.

ARTICLE TWO: SHAREHOLDERS

2.01 Annual Meetings. An annual meeting of shareholders of the Corporation shall be held during each calendar year on such date and at such time as shall be designated from time to time by the board of directors and stated in the notice of the meeting, if not a legal holiday in the place where the meeting is to be held, and, if a legal holiday in such place, then on the next business day following, at the time specified in the notice of the meeting. At such meeting, the shareholders shall elect directors and transact such other business as may properly be brought before the meeting.

2.02 Special Meetings. A special meeting of the shareholders may be called at any time by the president, the board of directors, or the holders of not less than ten percent of all shares entitled to vote at such meeting. Only business within the purpose or purposes described in the notice of special meeting may be conducted at such special meeting.

2.03 Place of Meetings. The annual meeting of shareholders may be held at any place within or without the State of Texas designated by the board of directors. Special meetings of shareholders may be held at any place within or without the State of Texas designated by the person or persons calling such special meeting as provided in Section 2.02 above. Meetings of shareholders shall be held at the principal office of the Corporation unless another place is designated for meetings in the manner provided herein.

3

2.04 Notice. Except as otherwise provided by law, written or printed notice stating the place, day, and hour of each meeting of the shareholders and, in case of a special meeting, the purpose or purposes for which the meeting is called, shall be delivered not less than ten nor more than sixty days before the date of the meeting, either personally or by mail, by or at the direction of the president, the secretary, or the person calling the meeting, to each shareholder of record entitled to vote at such meeting. If mailed, such notice shall be deemed to be delivered when deposited in the United States mail addressed to the shareholder at his address as it appears on the share transfer records of the corporation, with postage thereon prepaid.

2.05 Voting List. At least ten days before each meeting of shareholders, the secretary shall prepare a complete list of shareholders entitled to vote at such meeting, arranged in alphabetical order, including the address of each shareholder and the number of voting shares held by each shareholder. For a period of ten days prior to such meeting, such list shall be kept on file at the registered office or principal place of business of the Corporation and shall be subject to inspection by any shareholder during usual business hours. Such list shall be produced and kept open at such meeting, and at all times during such meeting shall be subject to inspection by any shareholder. The original share transfer records shall be prima facie evidence as to who are the shareholders entitled to examine such list or transfer records or to vote at any meeting of shareholders.

2.06 Voting of Shares. Treasury shares, shares of the Corporation’s own stock owned by another corporation the majority of the voting stock of which is owned or controlled by the Corporation, and shares of the Corporation’s own stock held by the Corporation in a fiduciary capacity shall not be shares entitled to vote or to be counted in determining the total number of outstanding shares. Shares standing in the name of another domestic or foreign corporation of any type or kind may be voted by such officer, agent, or proxy as the bylaws of such corporation may authorize or, in the absence of such authorization, as the board of directors of such corporation may determine. Shares held by an administrator, executor, guardian, or conservator may be voted by him, either in person or by proxy, without transfer of such shares into his name so long as such shares form a part of the estate served by him and are in the possession of such estate. Shares held by a trustee may be voted by him, either in person or by proxy, only after the shares have been transferred into his name as trustee. Shares standing in the name of a receiver may be voted by such receiver, and shares held by or under the control of a receiver may be voted by such receiver without transfer of such shares into his name if authority to do so is contained in the court order by which such receiver was appointed. A shareholder whose shares are pledged shall be entitled to vote such shares until they have been transferred into the name of the pledgee, and thereafter, the pledgee shall be entitled to vote such shares.

2.07 Quorum; Withdrawal of Quorum. A quorum shall be present at a meeting of shareholders if the holders of a majority of the shares entitled to vote are represented at the meeting in person or by proxy, except as otherwise provided by law or the certificate of formation. If a quorum shall not be present at any meeting of shareholders, the shareholders represented in person or by proxy at such meeting may

4

adjourn the meeting until such time and to such place as may be determined by a vote of the holders of a majority of the shares represented in person or by proxy at that meeting. Once a quorum is present at a meeting of shareholders, the shareholders represented in person or by proxy at the meeting may conduct such business as may be properly brought before the meeting until it is adjourned, and the subsequent withdrawal from the meeting of any shareholder or the refusal of any shareholder represented in person or by proxy to vote shall not affect the presence of a quorum at the meeting.

2.08 Majority Vote. Directors of the Corporation shall be elected by a plurality of the votes cast by the holders of shares entitled to vote in the election of directors of the Corporation at a meeting of shareholders at which a quorum is present. Except as otherwise provided by law, the certificate of formation, or these bylaws, with respect to any matter, the affirmative vote of the holders of a majority of the Corporation’s shares entitled to vote on that matter and represented in person or by proxy at a meeting at which a quorum is present shall be the act of the shareholders.

2.09 Method of Voting; Proxies. Every shareholder of record shall be entitled at every meeting of shareholders to one vote on each matter submitted to a vote, for every share standing in his name on the original share transfer records of the Corporation except to the extent that the voting rights of the shares of any class or classes are increased, limited, or denied by the certificate of formation. Such share transfer records shall be prima facie evidence as to the identity of shareholders entitled to vote. At any meeting of shareholders, every shareholder having the right to vote may vote either in person or by a proxy executed in writing by the shareholder or by his duly authorized attorney-in-fact. Each such proxy shall be filed with the secretary of the Corporation before, or at the time of, the meeting. No proxy shall be valid after eleven months from the date of its execution, unless otherwise provided in the proxy. If no date is stated on a proxy, such proxy shall be presumed to have been executed on the date of the meeting at which it is to be voted. Each proxy shall be revocable unless the proxy form conspicuously states that the proxy is irrevocable and the proxy is coupled with an interest.

2.10 Closing of Transfer Records; Record Date. For the purpose of determining shareholders entitled to notice of, or to vote at, any meeting of shareholders or any adjournment thereof, or entitled to receive a distribution (other than a distribution involving a purchase or redemption by the Corporation of any of its own shares) or a share dividend, or in order to make a determination of shareholders for any other proper purpose (other than determining shareholders entitled to consent to action by shareholders proposed to be taken without a meeting of shareholders), the board of directors may provide that the share transfer records of the Corporation shall be closed for a stated period but not to exceed in any event sixty days. If the share transfer records are closed for the purpose of determining shareholders entitled to notice of, or to vote at, a meeting of shareholders, such records shall be closed for at least ten days immediately preceding such meeting. In lieu of closing the share transfer records, the board of directors may fix in advance a date as the record date for any such determination of shareholders, such date in any case to be not more than sixty days and, in case of a meeting of shareholders, not less than ten days prior to the date on which the particular

5

action requiring such determination of shareholders is to be taken. If the share transfer records are not closed and if no record date is fixed for the determination of shareholders entitled to notice of, or to vote at, a meeting of shareholders or entitled to receive a distribution (other than a distribution involving a purchase or redemption by the Corporation of any of its own shares) or a share dividend, the date on which the notice of the meeting is mailed or the date on which the resolution of the board of directors declaring such distribution or share dividend is adopted, as the case may be, shall be the record date for such determination of shareholders. When a determination of shareholders entitled to vote at any meeting of shareholders has been made as provided in this Section 2.10, such determination shall apply to any adjournment thereof except where the determination has been made through the closing of the share transfer records and the stated period of closing has expired.

2.11 Officers Duties at Meetings. The president shall preside at, and the secretary shall prepare minutes of, each meeting of shareholders, and in the absence of either such officer, his duties shall be performed by some person or persons elected by the vote of the holders of a majority of the outstanding shares entitled to vote, present in person or represented by proxy.

2.12 Action Without Meeting. Any action which may be taken, or which is required by law or the certificate of formation or bylaws of the Corporation to be taken, at any annual or special meeting of shareholders, may be taken without a meeting, without prior notice, and without a vote, if a consent or consents in writing, setting forth the action so taken, shall have been signed by the holder or holders of shares having not less than the minimum number of votes that would be necessary to take such action at a meeting at which the holders of all shares entitled to vote on the action were present and voted. The signed consent or consents of shareholders shall be placed in the minute books of the Corporation.

3.04 Removal. At any meeting of shareholders called expressly for that purpose, any director or the entire board of directors may be removed, with or without cause, by a vote of the holders of a majority of the shares then entitled to vote on the election of directors.

Any vacancy occurring in the board of directors may be filled by (i) the shareholders at any annual or special meeting of shareholders called for that purpose or (ii) the affirmative vote of a majority of the remaining directors though less than a quorum of the board of directors. A director elected to fill a vacancy shall be elected to serve for the unexpired term of his predecessor in office. Notwithstanding the foregoing, whenever the holders of any class or series of shares are entitled to elect one or more directors by the provisions of the certificate of formation, any vacancies in such directorship(s) may be filled by the affirmative vote of a majority of the directors elected by such class or series then in office or by a sole remaining director so elected or by the vote of the holders of the outstanding shares of such class or series, and such directorship(s) shall not in any case be filled by the vote of the remaining directors or the holders of the outstanding shares of the Corporation as a whole unless otherwise provided in the certificate of formation.

3.06 Place of Meetings. The board of directors may hold its meetings in such place or places within or without the State of Texas as the board of directors may from time to time determine.

If a quorum is not present at a meeting, a majority of the directors present may adjourn the meeting from time to time, without notice other than an announcement at the meeting, until a quorum is present. The act of a majority of the directors present at a meeting at which a quorum is in attendance shall be the act of the board of directors, unless the act of a greater number is required by law, the certificate of formation, or these bylaws.

3.11 Procedure; Minutes. At meetings of the board of directors, business shall be transacted in such order as the board of directors may determine from time to time. The board of directors shall appoint at each meeting a person to preside at the meeting and a person to act as secretary of the meeting. The secretary of the meeting shall prepare minutes of the meeting which shall be delivered to the secretary of the Corporation for placement in the minute books of the Corporation.

3.12 Presumption of Assent. A director of the Corporation who is present at any meeting of the board of directors at which action on any matter is taken shall be presumed to have assented to the action unless his dissent shall be entered in the minutes of the meeting or unless he shall file his written dissent to such action with the person acting as secretary of the meeting before the adjournment thereof or shall forward any dissent by certified or registered mail to the secretary of the Corporation immediately after the adjournment of the meeting. Such right to dissent shall not apply to a director who voted in favor of such action.

3.13 Compensation. Directors, in their capacity as directors, may receive, by resolution of the board of directors, a fixed sum and expenses of attendance, if any, for attending meetings of the board of directors or a stated salary.

3.14 Action Without Meeting. Any action which may be taken, or which is required by law, the certificate of formation, or these bylaws to be taken, at a meeting of the board of directors or any committee may be taken without a meeting if a consent in writing, setting forth the action so taken, shall have been signed by all of the members of the board of directors or committee, as the case may be, and such consent shall have the same force and effect, as of the date stated therein, as a unanimous vote of such members of the board of directors or committee, as the case may be, and may be stated as such in any document or instrument filed with the Secretary of State of Texas or in any certificate or other document delivered to any person. The consent may be in one or more counterparts so long as each director or committee member signs one of the counterparts. The signed consent shall be placed in the minute books of the Corporation.
