Southern Industrial Services, Inc., a corporation organized and existing under and by virtue of the Delaware General Corporation Law (the “corporation”), does hereby certify:

FIRST: That by action by unanimous consent in lieu of a meeting, the Board of Directors of the corporation duly adopted resolutions setting forth proposed amendments, adding Articles ELEVENTH and TWELFTH to the Certificate of Incorporation of said corporation, declaring said amendments to be advisable and directing that said amendments be adopted by unanimous consent of the stockholders in lieu of a meeting. The proposed amendments are as follows:

“ELEVENTH. Each person who at any time is, or shall have been, a director or officer of the corporation, and who was or is a party, or is threatened to be made a party, to any threatened, pending or completed action, suit or proceeding, whether civil, criminal, administrative or investigative, by reason of the fact that such person is or was a director or officer of the corporation, or served at the request of the corporation as a director, officer, employee, trustee or agent of another corporation, partnership, joint venture, trust or other enterprise, shall be indemnified by the corporation against all expenses (including attorneys’ fees), judgments, fines and amounts paid in settlement actually and reasonably incurred by such director or officer in connection with any such action, suit or proceeding to the full extent permitted by the laws of the State of Delaware. The right to indemnification conferred in this Article shall be a contract right and shall include the right to be paid by the corporation for expenses incurred in defending any such proceeding in advance of its final disposition upon delivery to the corporation of an undertaking, by or on behalf of such director or officer, to repay all amounts so advanced if it should be determined ultimately that such director or officer is not entitled to be indemnified under this Article or otherwise. The foregoing right of indemnification shall in no way exclude any other rights of indemnification to which any such director or officer may be entitled, under any bylaw, agreement, vote of stockholders or directors or otherwise. All rights of indemnification hereunder shall continue as to a person who has ceased to be a director or officer and shall inure to the benefit of the heirs, executors and administrators of any such director or officer.”

“TWELFTH. (A) A director of the corporation shall not be personally liable to the corporation or its stockholders for monetary damages for breach of fiduciary duty as a director, except for liability (1) for any breach of the director’s duty of loyalty to the corporation or its stockholders, (2) for acts or omissions not in good faith or which involve intentional misconduct or a knowing violation of law, (3) under Section 174 of the Delaware General Corporation Law, or (4) for any transaction from which the director derived an improper personal benefit. If the Delaware General Corporation Law is amended after approval by the stockholders of this provision to authorize corporate action further eliminating or limiting the personal liability of directors, then the liability of a director of this corporation shall be eliminated or limited to the fullest extent permitted by the Delaware General Corporation Law, as so amended.

“(B) Any repeal or modification of this Article TWELFTH of the Certificate of Incorporation by the stockholders of the corporation shall not adversely affect any right or protection of a director of the corporation existing at the time of such repeal or modification.”

SECOND: That thereafter, pursuant to Sections 228 and 242 of the Delaware General Corporation Law, all of the stockholders of the corporation consented in writing to the adoption of said amendments.

THIRD: That said amendments were duly adopted in accordance with the provisions of Sections 228 and 242 of the Delaware General Corporation Law.
