CERTIFICATE OF AMENDMENT
TO THE
CERTIFICATE OF INCORPORATION
OF
MURCO DRILLING CORPORATION
MURCO DRILLING CORPORATION, a corporation organized and existing under and by virtue of the General Corporation Law of the State of Delaware, does hereby certify:
FIRST: That the Board of Directors of the Corporation, by unanimous written consent, adopted a resolution approving and adopting the following amendment to the Certificate of Incorporation of the Corporation:
RESOLVED, that the Certificate of Incorporation of MURCO DRILLING CORPORATION be amended by changing the Article thereof numbered “Fourth” so that, as amended, such Article shall read in its entirety as follows:
FOURTH. (A) Authorized Capital Stock. The maximum number of shares that the corporation is authorized to have outstanding shall be sixteen thousand (16,000) shares, classified as follows:

| (i) |  | Ten thousand (10,000) shares shall be Common Stock without par value (the “Common Stock”),
| (ii) |  | Five thousand (5,000) shares shall be Class A Preferred Stock, of the par value of one thousand dollars ($1,000.00) per share (the “Class A Preferred Stock”), and
| (iii) |  | One thousand (1,000) shares shall be Class B Preferred Stock, of the par value of one thousand dollars ($1,000.00) per share (the “Class B Preferred Stock”).

The voting powers, preferences and relative, participating, optional or other special rights of, and the qualifications, limitations or restrictions on, each class of capital stock of the Corporation shall be as set forth in this Article Fourth and as provided by law.
(B) Dividends. (i) The holders of the outstanding shares of Class A Preferred Stock and Class B Preferred Stock shall be entitled to receive, out of the funds legally available for the payment thereof, cash dividends, whether declared by the Board of Directors or not, at the annual dividend rate for each particular class as herein provided, but no more, payable semi-annually on the last days of June and December of each year following the date of their issuance, unless otherwise provided herein (a “Payment Date”). With respect to each Payment Date, the dividend payable thereon shall be paid to the shareholders of record as of such date.

#####

(ii) Dividends shall accrue, whether or not they have been declared and whether or not there are earnings or funds legally available for the payment of such dividends, (a) from the date of issuance, on each share of Class B Preferred Stock at the rate of $40.00 per share per annum, and (b) from the first anniversary date of issuance, on each share of Class A Preferred Stock as follows:

| (A) |  | at the rate of $40.00 per share per annum from such date until the Redemption Date (as hereinafter defined), and
| (B) |  | if still outstanding after the Redemption Date, at the rate of $150.00 per share per annum from such date until the redemption of all of the outstanding Class A Preferred Stock.

Dividends upon each share of Class A Preferred Stock and Class B Preferred Stock shall be cumulative so that if at any time such dividends in respect to any previous year at the applicable rate per annum shall not have been paid on either the Class A Preferred Stock or the Class B Preferred Stock, the deficiency shall be fully paid on such shares before the Corporation makes any distributions to the holders of the Common Stock, all in accordance with the provisions hereof. The accumulations of dividends, however, shall not bear interest, whether or not payment of dividends is made on a Payment Date.
(iii) The holders of the Class A Preferred Stock and Class B Preferred Stock shall not be entitled to receive any dividends thereon other than the dividends referred to in this Section B of Article Fourth.
(iv) In no event, so long as any shares of Class A Preferred Stock shall be outstanding, shall any dividend, whether in cash or property, be paid or declared, nor shall any distribution be made, on any shares of Common Stock, nor shall any shares of Class B Preferred Stock or Common Stock be purchased, redeemed or otherwise acquired for value by the Corporation.
(v) Subject to the foregoing provisions of this Section B of Article Fourth, and the limitations prescribed therein, the Board of Directors may declare, out of any funds legally available therefor, dividends (payable in cash, shares or otherwise) upon the then outstanding shares of Common Stock, and no holders of the Class A Preferred Stock or the Class B Preferred Stock shall be entitled to share therein.
(C) Liquidation Preferences. (i) In the event of a voluntary or involuntary liquidation, dissolution or winding up of the Corporation, the holders of the Class A Preferred Stock shall be subordinate to all claims of the Corporation’s creditors but otherwise entitled to receive out of the assets of the Corporation

-2-

#####

available for distribution to shareholders, whether such assets are capital or surplus of any nature, an amount equal to $1,000.00 per share of Class A Preferred Stock, together with an amount equal to all accrued but unpaid dividends through that Payment Date falling on or immediately following the date that payment is made available to the holders of the Class A Preferred Stock, whichever is applicable, before any payment shall be made or any assets distributed to the holders of the Class B Preferred Stock or the holders of the Common Stock. Thereafter, the holders of the Class B Preferred Stock shall be entitled to receive out of the remaining assets of the Corporation available for distribution to shareholders, whether such assets are capital or surplus of any nature, an amount equal to $1,000.00 per share of Class B Preferred Stock, together with an amount equal to all accrued but unpaid dividends through that Payment Date falling on or immediately following the date that payment is made available to the holders of the Class B Preferred Stock, before any payment shall be made or any assets distributed to the holders of the Common Stock. Subject to all the rights of the holders of the Class A Preferred Stock and the holders of the Class B Preferred Stock as set forth above, the holders of the Common Stock shall be entitled to receive, ratably, all of the remaining assets of the Corporation, if any.
(ii) If the assets of the Corporation are not sufficient to pay, in full, the liquidation payments payable to the holders of outstanding shares of the Class A Preferred Stock, then the holders of all such shares shall share ratably in such distribution of assets in accordance with the amount that would be payable on such distribution if the amount to which the holders of the outstanding shares of Class A Preferred Stock are entitled were paid in full.
(iii) If, after payment to the holders of the Class A Preferred Stock, the remaining assets of the Corporation are not sufficient to pay in full the liquidation payments payable to the holders of the outstanding shares of the Class B Preferred Stock, then the holders of all such shares shall share ratably in such distribution of the remaining assets in accordance with the amount that would be payable on such distribution if the amount to which the holders of the outstanding shares of the Class B Preferred Stock are entitled were paid in full.
(D) Redemption. (i) Provided that there are funds legally available therefor, at the option of the Board of Directors, outstanding shares of Class A Preferred Stock and Class B Preferred Stock may be redeemed at any time at a redemption price of $1,000.00 per share, plus all accrued but unpaid dividends through that Payment Date falling on or immediately following the redemption date of such shares, whichever is applicable (the “Redemption Price”), by the Corporation upon 30 days’ prior written notice to the holders thereof; provided, however, that prior to the

-3-

#####

redemption or repurchase of any shares of Class B Preferred Stock, all of the outstanding shares of Class A Preferred Stock shall have been redeemed at the Redemption Price set forth herein. Shares of Common Stock may be redeemed or repurchased pursuant to applicable law, but only after all of the outstanding shares of Class B Preferred Stock shall have been redeemed at the Redemption Price set forth herein.
(ii) Provided that there are funds legally available for the redemption of all (or part) of the Class A Preferred Stock, all of the outstanding Class A Preferred Stock (or such portion thereof as may be redeemed by legally available funds) shall be redeemed no later than the third anniversary date of the issuance of the Class A Preferred Stock (the “Redemption Date”). If any of the outstanding Class A Preferred Stock remains unredeemed after the Redemption Date, then if and when funds, totalling the lesser of (x) $50,000 or (y) that amount necessary to redeem all of such remaining shares of Class A Preferred Stock at the Redemption Price, become legally available for the redemption of such shares, then no later than 5 days thereafter, the Corporation shall redeem that many full shares of Class A Preferred Stock that may be equal to such funds, until all of the outstanding shares of Class A Preferred Stock are redeemed.
(iii) Each holder of a share of preferred stock to be redeemed, shall present and surrender its certificate or certificates representing such preferred stock to the Corporation at its principal place of business, and thereupon the Redemption Price of such preferred stock shall be payable to or on the order of the person whose name appears on such certificate or certificates as the owner thereof and such surrendered certificate shall be cancelled. If less than all the shares represented by any such surrendered certificate are redeemed, a new certificate shall be issued representing the unredeemed shares. From and after the redemption of any share of preferred stock, unless default is made in the payment of the Redemption Price, all rights of the holder of such stock as a shareholder of the Corporation, except the right to receive the Redemption Price, shall cease and terminate, and such preferred stock shall not thereafter be transferred on the books of the Corporation or be deemed to be outstanding for any purposes whatsoever.
(E) Voting Rights. Except as otherwise provided by law, neither the Class A Preferred Stock nor the Class B Preferred Stock shall have any voting power nor shall the holders of such preferred stock as such be entitled to notice of meetings of shareholders, all rights to vote and all voting power being vested exclusively in the holders of the Corporation’s Common Stock.
(F) Transferability. The holders of either the Class A Preferred Stock or Class B Preferred Stock shall not transfer, assign, sell, convey, give, donate, alienate or otherwise dispose of any

-4-

#####

shares of such preferred stock without the prior written consent of the Corporation, which shall not be unreasonably withheld. Each transferee or assignee of, or successor in interest to, any shares of the Class A Preferred Stock or the Class B Preferred Stock shall be bound by the restrictions on the transferability of such shares of preferred stock set forth herein.
(G) Preemptive Rights. The holders of either the Class A Preferred Stock or Class B Preferred Stock shall, in case of the proposed issuance by the Corporation of, or the proposed granting, by the Corporation of rights or options to purchase, its equity shares of any class or any shares of other securities convertible into or carrying rights or options to purchase, its equity shares of any class if the issuance of the equity shares proposed to be issued or issuable upon exercise of such rights or options or upon conversion of such other securities would adversely affect or effectively dilute the then current percentage of equity holdings of such holders, have the right within 30 days’ written notice of such issuance to purchase such shares or other securities in such proportions as would, if such preemptive right were exercised, preserve the percentage of equity holdings of the holders at a price or prices not less favorable than the price or prices at which such shares or other securities are proposed to be offered for sale to others.
SECOND: That the foregoing amendment has been consented to and approved by all of the shareholders of the Corporation entitled to vote on the matter, by unanimous written consent in accordance with the provisions of section 228 of The General Corporation Law of the State of Delaware and filed with the Corporation.
THIRD: That the aforesaid amendment was duly adopted in accordance with the applicable provisions of Sections 242 and 228 of The General Corporation Law of the State of Delaware.

(iii) If, after payment to the holders of the Class A Preferred Stock, the remaining assets of the Corporation are not sufficient to pay in full the liquidation payments payable to the holders of the outstanding shares of the class B Preferred Stock, then the holders of all such shares shall share ratably in such distribution of the remaining assets in accordance with the amount that would be payable on such distribution if the amount to which the holders of the outstanding shares of the class B Preferred Stock are entitled were paid in full.

thereof; provided, however, that prior to the redemption or repurchase of any shares of Class B Preferred Stock, all of the outstanding shares of Class A Preferred Stock shall have been redeemed at the Redemption Price set forth herein. Shares of Common Stock may be redeemed or repurchased pursuant to applicable law, but only after all of the outstanding shares of Class B Preferred Stock shall have been redeemed at the Redemption Price set forth herein.

If any of the outstanding Class A Preferred Stock remains unredeemed after the Redemption Date, then if and when funds, totalling the lesser of (x) $50,000 or (y) that amount necessary to redeem all of such remaining shares of Class A Preferred Stock at the Redemption Price, become legally available for the redemption of such shares, then no later than 5 days thereafter, the Corporation shall redeem that many full shares of Class A Preferred Stock that may be equal to such funds, until all of the outstanding shares of Class A Preferred Stock are redeemed.
(iii) Each holder of a share of preferred stock to be redeemed, shall present and surrender its certificate or certificates representing such preferred stock to the Corporation at its principal place of business, and thereupon the Redemption Price of such preferred stock shall be payable to or on the order of the person whose name appears on such certificate or certificates as the owner thereof and such surrendered certificate shall be cancelled. If less than all the shares represented by any such surrendered certificate are redeemed, a new certificate shall be issued representing the unredeemed shares. From and after the redemption of any share of preferred stock, unless default is made in the payment of the Redemption Price, all rights of the holder of such stock as a shareholder of the Corporation, except the right to receive the Redemption Price, shall cease and terminate, and such preferred stock shall not thereafter be transferred on the books of the Corporation or be deemed to be outstanding for any purposes whatsoever.

Except as otherwise provided by law, neither the Class A Preferred Stock nor the class B Preferred Stock shall have any voting power nor shall the holders of such preferred stock as such be entitled to notice of meetings of shareholders, all rights to vote and all voting power being vested exclusively in the holders of the Corporation’s Common Stock.
