To consider and vote upon a proposal to permit us to adjourn the special meeting to a date not later than , 2003 to permit further solicitation of proxies if there are not sufficient votes at the time of the meeting to approve the merger proposal. A copy of the merger agreement is attached as Annex A to the accompanying proxy statement/prospectus. Only those TMBR/Sharp shareholders who were holders of record of TMBR/Sharp Shares at the close of business on , 2003 will be entitled to notice of, and to vote at, the special meeting and any adjournment or postponement of the meeting. A list of those shareholders will be available for review at TMBR/Sharp's principal executive office during normal business hours for a period of ten days before the special meeting. TMBR/Sharp cannot complete the merger unless it obtains the affirmative vote of the holders of at least two-thirds of the outstanding shares of its common stock entitled to vote at the special meeting to approve the merger agreement. TMBR/Sharp shareholders who do not vote in favor of approval of the merger agreement will have the right to seek appraisal of the fair value of their TMBR/Sharp Shares if the merger is completed, but only if they submit a written demand for an appraisal before TMBR/Sharp takes the vote on the merger agreement, and if they comply with Texas law as explained in the accompanying proxy statement/prospectus. YOUR VOTE IS IMPORTANT.

IF YOU RECEIVE MORE THAN ONE PROXY CARD BECAUSE YOUR SHARES ARE REGISTERED IN DIFFERENT NAMES OR ADDRESSES, EACH PROXY CARD SHOULD BE COMPLETED, SIGNED, DATED AND RETURNED TO ENSURE THAT ALL OF YOUR SHARES WILL BE VOTED. FAILURE TO RETURN A PROPERLY EXECUTED PROXY CARD OR VOTE AT THE SPECIAL MEETING WILL HAVE THE SAME EFFECT AS A VOTE AGAINST THE APPROVAL OF THE MERGER AGREEMENT BUT, ASSUMING A QUORUM IS PRESENT, WILL HAVE NO EFFECT ON THE ADJOURNMENT PROPOSAL. Your proxy is revocable and will not affect your right to vote in person if you decide to attend the special meeting. Simply attending the special meeting, however, will not revoke your proxy. For an explanation of the procedures for revoking your proxy, see the section of the accompanying proxy statement/prospectus captioned "The Special Meeting -- Voting." Returning your proxy card without indicating how you want to vote will have the same effect as a vote FOR the approval of the merger agreement and FOR the approval of the adjournment proposal.

STOCK CERTIFICATES IN EXCHANGE FOR YOUR RIGHT TO RECEIVE $9.09 IN CASH AND 0.312166 OF A SHARE OF COMMON STOCK, $0.01 PAR VALUE PER SHARE, OF PATTERSON-UTI ENERGY, INC.

iii QUESTIONS AND ANSWERS ABOUT THE MERGER THE FOLLOWING QUESTIONS AND ANSWERS BRIEFLY ADDRESS SOME COMMONLY ASKED QUESTIONS ABOUT THE SPECIAL MEETING AND THE MERGER. THEY MAY NOT INCLUDE ALL THE INFORMATION THAT IS IMPORTANT TO YOU. WE URGE YOU TO READ CAREFULLY THIS ENTIRE PROXY STATEMENT/PROSPECTUS, INCLUDING THE ANNEXES AND THE OTHER DOCUMENTS WE REFER TO IN THIS PROXY STATEMENT/PROSPECTUS. FREQUENTLY USED TERMS We have generally avoided the use of technical defined terms in this proxy statement/prospectus but a few frequently used terms may be helpful for you to have in mind at the outset. We refer to: - Patterson-UTI Energy, Inc., a Delaware corporation, as "Patterson-UTI"; - TMBR/Sharp Drilling, Inc., a Texas corporation, as "TMBR/Sharp"; - Patterson-UTI Acquisition, LLC, a newly formed Texas limited liability company and a wholly owned subsidiary of Patterson-UTI, as "Sub"; - the merger of TMBR/Sharp into Sub and the conversion of TMBR/Sharp Shares into the right to receive cash and Patterson-UTI Shares as "the merger"; - the agreement and plan of merger among Patterson-UTI, Sub and TMBR/Sharp as "the merger agreement"; - the special meeting of holders of TMBR/Sharp Shares described on page 14 as "the special meeting"; - the common stock, par value $0.01 per share, of Patterson-UTI as "Patterson-UTI Shares"; - the common stock, par value $0.10 per share, of TMBR/Sharp as "TMBR/Sharp Shares"; - the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended, as the "HSR Act"; and - the Texas Business Corporation Act as "the TBCA". SPECIAL MEETING; VOTES REQUIRED Q: When and where is the special meeting? A: The special meeting of TMBR/Sharp shareholders will be held at : a.m., local time, on , 2003, at the Midland Petroleum Club, 501 West Wall, Midland, Texas. Q: Who can vote on the proposals being presented at the special meeting? A: Holders of TMBR/Sharp Shares outstanding at the close of business on , 2003, the record date for the special meeting, may vote in person or by proxy on the proposal to approve the merger agreement and on the adjournment proposal. The vote of Patterson-UTI stockholders is not required and will not be taken to approve the merger agreement or the adjournment proposal. Q: What are TMBR/Sharp shareholders being asked to vote upon? A: TMBR/Sharp shareholders are being asked to approve the merger agreement that provides for TMBR/Sharp to be merged with and into Sub. If the merger is completed, TMBR/Sharp will no longer be a publicly traded corporation and its shareholders will no longer own TMBR/Sharp Shares. In addition, TMBR/Sharp shareholders are being asked to approve the adjournment proposal to permit TMBR/Sharp to adjourn the special meeting to a date not later than , 2003 to permit the further solicitation of proxies if there are not sufficient votes at the time of the special meeting to approve the merger agreement. Q: What vote is required to approve the merger agreement and to approve the adjournment proposal? A: The merger cannot be completed unless the holders of at least two-thirds of the outstanding TMBR/Sharp Shares entitled to vote at the special meeting vote in favor of the merger. Even if the vote set iv forth above is obtained at the special meeting, we cannot assure you that the merger will be completed because the completion of the merger is subject to the satisfaction or waiver of other conditions discussed in this proxy statement/prospectus. The affirmative vote of the holders of a majority of the TMBR/Sharp Shares, entitled to vote at the special meeting and present in person or by proxy, is required to approve the adjournment proposal. Q: What happens if I vote against the merger agreement proposal? A: If you vote against the merger agreement but the required vote is obtained, the merger may be completed and, if completed, you will be entitled to receive the merger consideration for your shares unless you have perfected your dissenters' rights in accordance with Texas law. Q: What effect does a failure to return a properly executed proxy card, a failure to vote in person at the special meeting, or an abstention from the vote have on the merger agreement proposal and the adjournment proposal? A: Failure to return a properly executed proxy card or to vote at the special meeting, or an abstention from the vote, will have the same effect as a vote against the approval of the merger agreement. Assuming a quorum is present at the special meeting, the failure to return a properly executed proxy card or to vote at the special meeting will have no effect on the adjournment proposal, and an abstention from the vote on the adjournment proposal will have the same effect as a vote against the adjournment proposal. Q: Have any shareholders agreed to vote in favor of the approval of the merger agreement? A: TMBR/Sharp has represented to Patterson-UTI that each director and officer of TMBR/Sharp has represented to TMBR/Sharp his or her intention to vote in favor of the approval of the merger agreement. Patterson-UTI intends to vote in favor of the merger proposal and the adjournment proposal. At November 1, 2003, the officers and directors of TMBR/Sharp collectively owned 262,250 TMBR/Sharp Shares, which represented the right to vote or direct the vote of approximately 4.76% of the outstanding TMBR/Sharp Shares on November 1, 2003. At that same date, Patterson-UTI owned 1,058,673 TMBR/Sharp Shares, which represented the right to vote approximately 19.23% of the outstanding TMBR/Sharp Shares. Q: If my shares are held in "street name" by my broker, will my broker vote my shares for me? A: TMBR/Sharp Shares will be voted for or against the merger proposal and for or against the adjournment proposal only if TMBR/Sharp shareholders provide written instructions to their broker as to how to vote their shares. If you want your broker to vote your shares in favor of the merger proposal and the adjournment proposal, you should follow the directions provided by your broker regarding how to instruct your broker to vote your TMBR/Sharp Shares. Without instructions, your TMBR/Sharp Shares will not be voted by your broker and the failure to vote will have the same effect as a vote AGAINST the approval of the merger agreement but, assuming a quorum is present at the special meeting, will have no effect on the adjournment proposal. Q: Can I change my vote after I have mailed a signed proxy card? A: Yes. You can change your vote at any time before the vote is taken at the special meeting. If you hold your TMBR/Sharp Shares in "street name" and have instructed a broker to vote your TMBR/Sharp Shares, you must follow the directions received from your broker as to how to change your vote. If you are the record holder of your TMBR/Sharp Shares, you can do this in one of the following three ways: - you can send a written notice to TMBR/Sharp's secretary dated later than your proxy card stating that you would like to revoke your current proxy; - you can complete and submit a new proxy card dated later than your original proxy card; or - you can attend the special meeting and vote in person. v If you choose to submit a notice of revocation or a new proxy card you must send it to the Secretary of TMBR/Sharp at 4607 West Industrial Blvd., Midland, Texas 79703. TMBR/Sharp must receive the notice or new proxy card before the vote is taken at the special meeting. THE MERGER Q: Why are Patterson-UTI and TMBR/Sharp proposing the merger? A: Our companies are proposing the merger because we believe that the combination of the operations and resources of our two companies will result in a combined company that is stronger than either company operating alone. We also believe that the merger will result in improved shareholder liquidity for TMBR/Sharp shareholders, including the opportunity to receive a cash payment and to continue as a shareholder of a larger and more competitive combined company. Q: What will I receive for my TMBR/Sharp Shares if the merger is completed? A: If the merger is completed, each TMBR/Sharp Share (except those shares owned directly or indirectly by TMBR/Sharp or Patterson-UTI, and those shares held by dissenting shareholders) will be converted into the right to receive $9.09 in cash and 0.312166 of a Patterson-UTI Share. TMBR/Sharp Shares directly or indirectly owned or held by Patterson-UTI or TMBR/Sharp will be canceled. Patterson-UTI will not issue fractional shares to TMBR/Sharp shareholders. Instead, Patterson-UTI will pay cash for any fractional shares. Based on the closing price of Patterson-UTI Shares and TMBR/Sharp Shares on the trading day immediately preceding the execution of the merger agreement, the cash and stock consideration to be received in the merger by TMBR/Sharp shareholders is $20.20 per TMBR/Sharp Share, which represented on that trading day a 4.12% premium. Because the exchange ratio is a fixed ratio that will not be adjusted as a result of any increase or decrease in the price of Patterson-UTI Shares or TMBR/Sharp Shares, the value of the cash and stock consideration actually received in the merger by TMBR/Sharp shareholders may be more or less than $20.20 per share. Q: What if there is a reclassification, recapitalization, stock combination, stock split, stock dividend or share exchange of Patterson-UTI Shares or TMBR/Sharp Shares before the merger is completed? A: If, before the effective time of the merger, the issued and outstanding Patterson-UTI Shares or TMBR/Sharp Shares are changed into a different number of shares as a result of a reclassification, recapitalization, stock split, stock combination, stock dividend or share exchange, we will make an appropriate and proportionate adjustment to the number of Patterson-UTI Shares to be received by the TMBR/Sharp shareholders. Q: What will I receive in connection with the merger if I hold stock options to acquire TMBR/Sharp Shares? A: If the TMBR/Sharp shareholders approve the merger agreement, after the special meeting but before the completion of the merger, TMBR/Sharp will make a cash payment to each holder of a stock option granted under a TMBR/Sharp benefit plan in exchange for the cancellation and termination of the option. The cash amount to be paid for each TMBR/Sharp Share subject to the option will equal the difference between $20.20 and the exercise price per TMBR/Sharp Share subject to the option, less applicable withholding taxes. All stock options to purchase TMBR/Sharp Shares will vest after the merger is approved at the special meeting and before the completion of the merger. Q: What does the TMBR/Sharp board of directors recommend regarding the merger agreement and the adjournment proposal? A: The TMBR/Sharp board of directors has unanimously determined that the proposed merger is fair to and in the best interests of TMBR/Sharp and its shareholders, and it has unanimously recommended that the TMBR/Sharp shareholders approve the merger agreement and the adjournment proposal. The TMBR/Sharp board of directors adopted a resolution approving and authorizing the merger agreement vi and the adjournment proposal. THE BOARD OF DIRECTORS OF TMBR/SHARP RECOMMENDS THAT THE TMBR/ SHARP SHAREHOLDERS VOTE TO APPROVE THE MERGER AGREEMENT AND THE ADJOURNMENT PROPOSAL. Q: Do any members of the board of directors or management of TMBR/Sharp have interests in the merger that are different from my interests as a shareholder? A: Some TMBR/Sharp directors and officers have interests in the merger that are different from, or in addition to, the interests of TMBR/Sharp shareholders generally. In addition to consideration to be received for their TMBR/Sharp Shares, eight officers and directors of TMBR/Sharp will receive compensatory payments as a result of the merger. These additional interests include a retention payment of $700,800 payable to Thomas C. Brown, the chairman of the board and chief executive officer of TMBR/Sharp. As of November 1, 2003, Mr. Brown also will receive approximately $3,482,625 in exchange for the cancellation and termination of his stock options to purchase TMBR/Sharp Shares. For additional information regarding these interests, we urge you to read carefully the section of this proxy statement/prospectus titled "The Merger -- Interests of Certain Persons in the Merger". Q: Are there conditions to the completion of the merger? A: Yes, completion of the merger depends on a number of conditions being satisfied or waived. In addition to customary conditions relating to the accuracy of representations and warranties and the performance of obligations under the merger agreement, these conditions include the following: - approval of the merger agreement and the related transactions by the holders of at least two-thirds of the outstanding TMBR/Sharp Shares entitled to vote at the special meeting; - expiration or termination of the waiting period under the HSR Act (which has occurred) and the filing, occurrence or receipt of other authorizations, consents, orders, or approvals required to consummate the transactions contemplated by the merger agreement; - absence of any legal restraint or prohibition preventing the consummation of the merger; - absence of a material adverse change in TMBR/Sharp's business, operations or financial condition; - holders of no more than five percent (5%) of the outstanding TMBR/Sharp Shares entitled to vote at the special meeting shall have properly perfected their dissenters' rights; - receipt of opinions of counsel to Patterson-UTI and TMBR/Sharp that the merger will qualify as a reorganization within the meaning of Section 368(a) of the Internal Revenue Code of 1986, as amended; and - effectiveness of a registration statement covering the Patterson-UTI Shares, absence of an effective stop order suspending the effectiveness of the registration statement and receipt of all necessary state securities or "Blue Sky" authorizations. If these conditions are not satisfied or waived, the merger will not be completed even if the TMBR/Sharp shareholders vote to approve the merger agreement. Neither Patterson-UTI nor TMBR/Sharp will waive the condition to closing requiring receipt of opinions of counsel to Patterson-UTI and TMBR/Sharp that the merger will qualify as a reorganization within the meaning of Section 368(a) of the Code. If the opinions of counsel are not delivered, the parties will not proceed with the merger described in this proxy statement/prospectus. See "The Merger Agreement-Conditions Precedent" and "Material United States Federal Income Tax Consequences". Q: When do you expect the merger to be completed? A: Patterson-UTI and TMBR/Sharp expect that, assuming the conditions to the merger are satisfied or waived and TMBR/Sharp receives the requisite shareholder vote at the special meeting, the merger will be completed within two business days after the special meeting. vii Q: Will I owe any U.S. federal income tax as a result of the merger? A: Generally, a U.S. holder who receives the merger consideration will recognize gain (but not loss) in an amount equal to the lesser of (1) the amount of cash received pursuant to the merger, and (2) the amount, if any, that (a) the sum of the fair market value of the Patterson-UTI Shares as of the effective time of the merger and the amount of cash received pursuant to the merger exceeds (b) the U.S. holder's adjusted tax basis in the shares. Provided that the U.S. holder holds the TMBR/Sharp Shares as a capital asset, gain recognized upon the exchange generally will be capital gain, and any recognized capital gain will be long-term capital gain if the U.S. holder has held the TMBR/Sharp Shares for more than one year. See "Material United States Federal Income Tax Consequences". Q: What if the merger proposal is not approved? A: If the merger agreement is not approved by TMBR/Sharp's shareholders or if the merger is not otherwise completed, TMBR/Sharp intends to hold an annual meeting to elect directors and to conduct other business that may properly come before the meeting, as soon as practicable after the special meeting. Q: Is TMBR/Sharp required to pay a break-up fee if its shareholders do not approve the merger agreement? A: Yes, in certain circumstances surrounding the termination of the merger agreement, TMBR/Sharp must pay Patterson-UTI a termination fee of $3.5 million. See "The Merger Agreement -- Termination; -- Fees and Expenses". Q: What rights do I have to dissent from the merger? A: You may dissent from the merger and seek an appraisal of the fair value of your TMBR/Sharp Shares, but only if you comply with the requirements of the TBCA that are attached as Annex C to this proxy statement/prospectus and that are summarized in the section of this proxy statement/prospectus titled "The Merger -- Dissenters' Rights of Appraisal". Those requirements include filing a written objection to the merger prior to the special meeting, not voting in favor of approval of the merger agreement and making a demand for compensation. The appraised fair value of your TMBR/Sharp Shares, which will be paid if you properly perfect the appraisal rights available under Texas law, may be more than, less than or equal to the per share price to be paid by Patterson-UTI in the merger. If you contemplate exercising your dissenter's rights, you are urged to read carefully the provisions of the TBCA relating to dissenters' rights that are attached as Annex C to this proxy statement/prospectus. GENERAL Q: What do TMBR/Sharp shareholders need to do now? A: TMBR/Sharp shareholders should mark their vote on the accompanying proxy card and sign and mail it in the enclosed return envelope as soon as possible. If your shares are held in "street name" by your broker, you should provide written instructions to your broker, as directed by your broker, on how the broker should vote your shares. These actions will ensure that your shares will be represented at the special meeting. If you sign and send in the proxy card and do not indicate how you want to vote, your proxy will be voted FOR the approval of the merger agreement and FOR the approval of the adjournment proposal. If you do not vote by sending in your proxy card, voting in person at the special meeting or properly instructing your broker how to vote your shares, it will have the same effect as a vote AGAINST the approval of the merger agreement but, assuming a quorum is present at the special meeting, will have no effect on the adjournment proposal. We urge you to read carefully this proxy statement/prospectus before marking your vote on the accompanying proxy card, instructing your broker how to vote or voting in person. Q: Should TMBR/Sharp shareholders send in their stock certificates now? A: No. If the merger is completed, you will be sent written instructions for sending in stock certificates in exchange for the right to receive $9.09 in cash and 0.312166 of a Patterson-UTI Share for each TMBR/Sharp Share you hold. viii Q: What should I do if I receive more than one set of voting materials? A: You may receive more than one set of voting materials, including multiple copies of this proxy statement/prospectus and multiple proxy cards or voting instruction cards. For example, if you hold your shares in more than one brokerage account, you will receive a separate voting instruction card for each brokerage account in which you hold shares. If you are a holder of record and your shares are registered in more than one name, you will receive more than one proxy card. Please complete, sign, date and return each proxy card and voting instructions that you receive. Q: Who can help answer my questions?

INFORMATION ABOUT PATTERSON-UTI Based on publicly available information, Patterson-UTI believes it is the second largest owner of land-based drilling rigs in North America. Patterson-UTI primarily conducts its contract drilling operations in: - Texas; - New Mexico; - Oklahoma; - Louisiana; - Mississippi; - Utah; and - Western Canada (Alberta, British Columbia and Saskatchewan). As of November 17, 2003, Patterson-UTI had a drilling fleet of 343 drilling rigs. A drilling rig includes the structure, power source and machinery necessary to cause a drill bit to penetrate earth to a depth desired by the customer. Patterson-UTI provides drilling fluids, completion fluids and related services to oil and natural gas operators in West Texas, Southeast New Mexico, South Texas, East Texas, Oklahoma, the Gulf Coast regions of Texas and Louisiana, and the Gulf of Mexico. Drilling and completion fluids are used by oil and natural gas operators during the drilling process to control pressure when drilling oil and natural gas wells. Patterson-UTI provides pressure pumping services to oil and natural gas operators in the Appalachian Basin. These services consist primarily of well stimulation and cementing for completion of new wells and remedial work on existing wells. Patterson-UTI is also engaged in the development, exploration, acquisition and production of oil and natural gas. Patterson-UTI's oil and natural gas operations are focused in producing regions in West Texas, Southeast New Mexico and South Texas. Patterson Energy, Inc. and UTI Energy Corp. consummated a merger on May 8, 2001. The transaction was treated as a reorganization within the meaning of Section 368(a) of the Internal Revenue Code of 1986, as amended, and accounted for as a pooling of interests for financial accounting purposes. Historical financial statements and related financial and statistical data included or incorporated in this proxy statement/prospectus by reference have been restated to provide for the retroactive effect of the merger. Patterson-UTI was formed in 1978 and reincorporated in 1993 as a Delaware corporation. Its principal offices are located at 4510 Lamesa Highway, Snyder, Texas 79549 and its telephone number is (325) 574-6300. INFORMATION ABOUT TMBR/SHARP TMBR/Sharp is engaged in the following two lines of business: - the domestic onshore contract drilling of oil and gas wells; and - the acquisition, exploration for, development, production and sale of oil and natural gas. TMBR/Sharp provides domestic onshore contract drilling to major and independent oil and gas companies. TMBR/Sharp's drilling operations are focused in the Permian Basin of West Texas and Eastern New Mexico. In addition to drilling rigs, TMBR/Sharp provides the crews and most of the 1 ancillary equipment used in the operation of its drilling rigs. TMBR Sharp owns a fleet of 18 drilling rigs with a depth capacity ranging from 8,500 feet to 30,000 feet. TMBR/Sharp's oil and gas exploration and production operations complement its onshore drilling operations. These activities are focused in mature producing regions in the Permian Basin of West Texas and Eastern New Mexico. At March 31, 2003, TMBR/Sharp's total proved oil and gas revenues were estimated to have a standardized measure of discounted cash flows of $37.8 million. TMBR/Sharp was incorporated under the laws of Texas in October 1982 under the name TMBR Drilling, Inc. In August 1986, the company changed its name to TMBR/Sharp Drilling, Inc. TMBR/Sharp's principal executive offices are located at 4607 West Industrial Blvd., Midland, Texas 79703 and its telephone number is (432) 699-5050. INFORMATION ABOUT THE MERGER The following summary highlights selected information about the merger that was not discussed in "Questions and Answers about the Merger" beginning on page iv. On May 26, 2003, the TMBR/Sharp board of directors agreed to the acquisition of TMBR/Sharp by a wholly owned subsidiary of Patterson-UTI under the terms of the merger agreement described in this proxy statement/prospectus and attached as Annex A. The merger agreement is the legal document that governs the merger, and we urge you to read carefully that agreement. At the effective time of the merger, TMBR/Sharp will merge with and into Sub. Sub will be the surviving company under the name TMBR/Sharp Drilling, LLC, and will be a wholly owned subsidiary of Patterson-UTI. The separate corporate existence of TMBR/Sharp will cease at the effective time of the merger. OPINION OF TMBR/SHARP'S FINANCIAL ADVISOR (PAGE 26) TMBR/Sharp's board of directors received a written opinion from its financial advisor, Energy Capital Solutions, LLC, to the effect that as of the date of the merger agreement, the consideration described in the merger agreement to be received by TMBR/Sharp shareholders was fair from a financial point of view. We urge you to read carefully this opinion, which is attached as Annex B to this proxy statement/prospectus. The assumptions made, procedures followed, matters considered and limitations of the scope of review undertaken in rendering the opinion are described in detail beginning on page 26 of this proxy statement/prospectus. ECS' opinion is addressed to the TMBR/Sharp board of directors and does not constitute a recommendation to any TMBR/Sharp shareholder as to how any shareholder should vote in connection with the merger proposal and the adjournment proposal. BOARD OF DIRECTORS OF PATTERSON-UTI FOLLOWING THE MERGER (PAGE 39) None of the directors or officers of TMBR/Sharp will become a director or officer of Patterson-UTI in connection with the merger. Patterson-UTI currently has no arrangements or agreements with any of the officers of TMBR/Sharp regarding employment following completion of the merger. Patterson-UTI and Messrs. Brown, Phillips and Lawson, however, may consider employment or consulting arrangements in the future. 2 TERMINATION OF THE MERGER (PAGE 55) Patterson-UTI and TMBR/Sharp can agree at any time to terminate the merger agreement by mutual written consent. Also, the merger agreement can be terminated under different circumstances, including, but not limited to, the following: - by either Patterson-UTI or TMBR/Sharp, if: - the affirmative vote of the holders of two-thirds of the outstanding TMBR/Sharp Shares entitled to vote on the approval of the merger agreement and the related transactions is not obtained upon a vote at the special meeting or an adjournment thereof; or - the effective time of the merger has failed to occur on or before December 31, 2003, unless the failure is the result of a material breach of the merger agreement by the party seeking the termination; - by Patterson-UTI, if: - TMBR/Sharp fails to call and hold the special meeting by December 31, 2003; - TMBR/Sharp breaches any of its representations or warranties in, or fails to materially perform any of its covenants, agreements or obligations under, the merger agreement, subject to certain conditions; or - TMBR/Sharp's board of directors (i) withdraws or modifies, in any manner adverse to Patterson-UTI, its recommendation or approval of the merger agreement or the related transactions, or (ii) recommends or resolves to recommend to the TMBR/Sharp shareholders an acquisition proposal; - by TMBR/Sharp, if: - its shareholders have not approved the merger agreement, it has notified Patterson-UTI of its receipt of a superior proposal, it has not received a timely offer from Patterson-UTI that is no less favorable than the superior proposal, and it has paid a $3.5 million termination fee to Patterson-UTI; or - Patterson-UTI or Sub breaches any of its representations or warranties in, or fails to materially perform any of its covenants, agreements or obligations under, the merger agreement, subject to certain conditions. EXPENSES (PAGE 56) Each of Patterson-UTI, Sub and TMBR/Sharp will bear its own expenses in connection with the merger agreement and the related transactions, except that Patterson-UTI and TMBR/Sharp will share equally costs and expenses related to filings and other matters under the HSR Act. NO SOLICITATION BY TMBR/SHARP (PAGE 53) The merger agreement restricts the ability of TMBR/Sharp to solicit or engage in discussions or negotiations with a third party regarding a proposal to acquire a significant interest in TMBR/Sharp. However, if TMBR/Sharp receives an acquisition proposal from a third party that is more favorable to TMBR/Sharp shareholders, from a financial point of view, than the terms of the merger agreement and TMBR/Sharp complies with certain procedures contained in the merger agreement, TMBR/Sharp may furnish nonpublic information to that third party and engage in negotiations regarding an acquisition proposal with that third party, subject to certain conditions. ACCOUNTING TREATMENT (PAGE 40) Patterson-UTI will account for the merger under the purchase method of accounting for business combinations under generally accepted accounting principles in the United States. 3 MATERIAL UNITED STATES FEDERAL INCOME TAX CONSEQUENCES (PAGE 57) Patterson-UTI and TMBR/Sharp have made representations to both tax counsels, including a representation that holders of TMBR/Sharp Shares will receive in the merger an amount of Patterson-UTI Shares with a value equal to at least forty percent (40%) of the total consideration. The total consideration takes into account the amount of cash paid or deemed to be paid to holders of TMBR/Sharp Shares in connection with the merger, cash paid to holders of TMBR/Sharp Shares who perfect their dissenters' rights and cash paid by Patterson-UTI to acquire TMBR/Sharp Shares within twelve (12) months of the date of the merger agreement. Based in part on such representations, it is the opinion of Fulbright & Jaworski L.L.P., tax counsel for Patterson-UTI, and Haynes and Boone, LLP, tax counsel for TMBR/Sharp, that the merger when effected in accordance with the terms of the merger agreement, will be treated for United States federal income tax purposes as a "reorganization" within the meaning of Section 368(a) of the Internal Revenue Code. It is a condition to the closing of the merger that tax counsel for each of Patterson-UTI and TMBR/Sharp deliver opinions in the form attached to this proxy statement/prospectus as Annexes D-1 and D-2, respectively. If the facts in the representations described in the immediately preceding paragraph change as of the proposed closing of the merger, tax counsel may not be able to deliver those opinions at closing of the merger. For example, if the market price of Patterson-UTI Shares declines between the date hereof and the proposed closing of the merger or if holders of TMBR/Sharp Shares perfect their dissenters' rights, each tax counsel may not be able to deliver the required opinions at the closing of the merger. If these opinions are unable to be delivered at the closing of the merger, Patterson-UTI and TMBR/Sharp will not proceed with the merger on the terms described in this proxy statement/prospectus. If Patterson-UTI and TMBR/Sharp desire to proceed with a merger other than as a "reorganization" within the meaning of Section 368(a) of the Code, they will do so only after revising the structure of the transaction. In such case, an amended proxy statement/prospectus with revised disclosure regarding the new structure and the material United States federal income tax consequences will be mailed to you at least 20 days prior to the special meeting. If the shareholders have already voted to approve the merger, TMBR/Sharp would hold another special meeting to vote on the revised merger proposal after the amended proxy statement/prospectus had been mailed. The discussion of material United States federal income tax consequences contained in this proxy statement/prospectus is not a substitute for an individual analysis of the tax consequences of the merger to you. You are urged to consult a tax advisor regarding the particular federal, state, local and foreign tax consequences of the merger in light of your own situation. CERTAIN DIFFERENCES IN THE RIGHTS OF SHAREHOLDERS (PAGE 64) As a result of the merger, the holders of TMBR/Sharp Shares will become holders of Patterson-UTI Shares. The rights of TMBR/Sharp shareholders are currently governed by the TBCA and the articles of incorporation and bylaws of TMBR/Sharp. The rights of Patterson-UTI stockholders are governed by the Delaware General Corporation Law and the restated certificate of incorporation and amended and restated bylaws of Patterson-UTI. Because TMBR/Sharp is a Texas corporation and Patterson-UTI is a Delaware corporation, certain material differences arise between the rights of TMBR/Sharp shareholders and Patterson-UTI stockholders. See page 64 for summaries of material differences between the rights of TMBR/Sharp shareholders and Patterson-UTI stockholders. 4 COMPARATIVE PER SHARE MARKET PRICE INFORMATION (PAGE 13) Patterson-UTI Shares are traded on the Nasdaq National Market under the ticker symbol "PTEN", and TMBR/Sharp Shares are traded on the Nasdaq National Market under the ticker symbol "TBDI". On May 23, 2003, the last full trading day prior to public announcement of the merger, Patterson-UTI Shares closed at $35.59 per share and TMBR/Sharp Shares closed at $19.40 per share. On , 2003, the most recent practicable date prior to the date of this proxy statement/prospectus, the closing prices of the Patterson-UTI Shares and the TMBR/Sharp Shares were $ and $ , respectively. Although the exchange ratio is fixed, the market price of Patterson-UTI Shares will fluctuate prior to and after the merger. We urge you to obtain current market quotations prior to making any decision with respect to the merger. 5 SELECTED HISTORICAL AND UNAUDITED PRO FORMA FINANCIAL DATA SELECTED HISTORICAL CONSOLIDATED FINANCIAL DATA OF PATTERSON-UTI The following table presents selected historical consolidated financial data of Patterson-UTI as of and for each of the years in the five-year period ended December 31, 2002 and as of and for the nine-month periods ended September 30, 2003 and 2002.

9 RISK FACTORS In deciding whether to approve the merger agreement and the merger of TMBR/Sharp with Sub, we urge you to consider carefully all of the information we have included in this document and its annexes and all of the information we have included in the documents we have incorporated by reference, including the risk factors identified in "Forward Looking Statements and Cautionary Statements for the Purposes of the "Safe Harbor" Provisions of the Securities Litigation Reform Act of 1995" in Patterson-UTI's Annual Report for the year ended December 31, 2002, filed on Form 10-K. See "Where You Can Find More Information" on page 78. In addition, we urge you to pay particular attention to the following risks related to the merger and to your investment in Patterson-UTI following the merger: WE MAY NOT REALIZE THE BENEFITS OF INTEGRATING THE TWO COMPANIES. In deciding that the merger is in the best interests of our respective stockholders, the Patterson-UTI board of directors and the TMBR/Sharp board of directors considered the potential complementary effects of combining the two companies' assets, personnel and operational expertise. Integrating businesses, however, involves a number of special risks, including the possibility that management may be distracted from regular business concerns by the need to integrate operations, unforeseen difficulties in integrating operations and systems, problems concerning retaining and assimilating the employees of the combined company, challenges in retaining customers, and potential adverse short-term or long-term effects on operating results. If we cannot integrate our businesses successfully, we may fail to realize the benefits we expect to realize from the merger. THE VALUE OF THE CONSIDERATION TO BE PAID TO THE TMBR/SHARP SHAREHOLDERS IN THE MERGER WILL VARY AS A RESULT OF THE FIXED EXCHANGE RATIO AND STOCK PRICE FLUCTUATIONS. Under the terms of the merger agreement, each TMBR/Sharp Share (except those shares owned directly or indirectly by TMBR/Sharp or Patterson-UTI, and those shares held by dissenting shareholders), will be converted into $9.09 in cash and 0.312166 of a Patterson-UTI Share. This exchange ratio is a fixed ratio that will not be adjusted as a result of any increase or decrease in the price of Patterson-UTI Shares or TMBR/Sharp Shares. The prices of Patterson-UTI Shares and TMBR/Sharp Shares at the time the merger is completed may be higher or lower than their prices on the date of this document or on the date of the special meeting. Changes in the business, operations or prospects of Patterson-UTI or TMBR/Sharp, market assessments of the benefits of the merger and of the likelihood that the merger will be completed, regulatory considerations, oil and gas prices, general market and economic conditions or other factors may affect the prices of Patterson-UTI Shares or TMBR/Sharp Shares. Most of these factors are beyond our control. Because the merger will be completed only after the special meeting is held, there is no way to be sure that the price of Patterson-UTI Shares now, or on the date of the special meeting, will be indicative of its price at the time the merger is completed. We urge you to obtain current market quotations for both Patterson-UTI Shares and TMBR/Sharp Shares prior to making any decision with respect to the merger. SOME DIRECTORS AND EXECUTIVE OFFICERS OF TMBR/SHARP HAVE INTERESTS IN THE MERGER DIFFERENT FROM, OR IN ADDITION TO, THE INTERESTS OF TMBR/SHARP SHAREHOLDERS. Some of the directors and executive officers of TMBR/Sharp have interests in the merger that are different from, or in addition to, your interests as a TMBR/Sharp shareholder. These additional interests include a retention payment of $700,800 payable to Mr. Brown. As of November 1, 2003, Mr. Brown also will receive approximately $3,482,625 in exchange for the cancellation and termination of his stock options to purchase TMBR/Sharp Shares. You should consider these interests in determining whether to vote in favor of the merger agreement. See "The Merger -- Interests of Certain Persons in the Merger" beginning on page 37. 10 PATTERSON-UTI HAS PAID NO DIVIDENDS ON THE PATTERSON-UTI SHARES AND CURRENTLY HAS NO PLAN TO PAY DIVIDENDS. Patterson-UTI has not declared or paid cash dividends on the Patterson-UTI Shares in the past. Patterson-UTI currently has no plan to declare or pay any cash dividends on the Patterson-UTI Shares in the foreseeable future. In addition, the terms of Patterson-UTI's existing credit facility may limit payment of dividends without the prior written consent of the lenders. 11 FORWARD-LOOKING STATEMENTS This proxy statement/prospectus, including the documents incorporated by reference, includes "forward-looking statements" within the meaning of Section 27A of the Securities Act of 1933 and Section 21E of the Securities Exchange Act of 1934. All statements, other than statements of historical facts, included in this proxy statement/prospectus or the documents incorporated by reference that address activities, events or developments that Patterson-UTI or TMBR/Sharp expect, project, believe or anticipate will or may occur in the future are forward-looking statements. These include such matters as: - benefits, effects or results of the merger; - cost reductions, operating efficiencies or synergies and the integration of operations; - future stock market valuations; - timing of the merger; - tax and accounting treatment of the merger; - market conditions, expansion and other development trends in the drilling and exploration and production industries; - business strategies; - competitive position; - financing plans; - transaction related expenses; - expansion and growth of operations after the merger; and - future operating results and financial condition of Patterson-UTI after the merger. Patterson-UTI and TMBR/Sharp have based these statements on their assumptions and analyses in light of their experience and perception of historical trends, current conditions, expected future developments and other factors they believe are appropriate in the circumstances. These statements are subject to a number of assumptions, risks and uncertainties, including: - general economic and business conditions; - prices of oil and gas and industry expectations about future prices; - the business opportunities (or lack thereof) that may be presented to and pursued by both companies; - the ability to integrate the operations of TMBR/Sharp and Patterson-UTI; and - changes in laws or regulations. These factors are in addition to the risks described in the "Risk Factors" section of this proxy statement/prospectus and the "Risk Factors" and "Management's Discussion and Analysis of Financial Condition and Results of Operations" sections or similar sections of the documents incorporated by reference. Most of these factors are beyond the control of either company.

On May 23, 2003, the last full trading day before Patterson-UTI and TMBR/Sharp publicly announced the execution of the merger agreement, the closing prices of the Patterson-UTI Shares and the TMBR/Sharp Shares were $35.59 and $19.40, respectively. On , 2003, the most recent practicable date prior to the date of this proxy statement/prospectus, the closing prices of the Patterson-UTI Shares and the TMBR/Sharp Shares were $ and $ , respectively. Shareholders are urged to obtain current market quotations prior to making any decision with respect to the merger. Patterson-UTI has not declared or paid cash dividends on the Patterson-UTI Shares in the past. Patterson-UTI currently has no plan to declare or pay any cash dividends on the Patterson-UTI Shares in the foreseeable future. In addition, the terms of Patterson-UTI's existing credit facility may limit payment of dividends without the prior written consent of the lenders. 13 THE SPECIAL MEETING GENERAL A special meeting of TMBR/Sharp shareholders will be held on , 2003, : a.m., local time, at the Midland Petroleum Club, 501 West Wall, Midland, Texas 79701 for the purpose of voting upon the merger proposal and the adjournment proposal described below. The accompanying proxy is being solicited by TMBR/Sharp's board of directors and is to be voted at the special meeting or any adjournment or postponement thereof. TMBR/Sharp's board of directors has fixed , 2003 as the record date for the determination of shareholders entitled to receive notice of and to vote at the special meeting and any adjournment or postponement thereof. On the record date, there were TMBR/Sharp Shares outstanding. On the record date, there were approximately record holders of TMBR/Sharp Shares. SOLICITATION TMBR/Sharp will pay the costs of soliciting proxies from TMBR/Sharp shareholders as well as all mailing fees incurred in connection with this proxy statement/prospectus. TMBR/Sharp has engaged the services of D.F. King & Co., Inc. to solicit proxies and assist in the distribution of proxy materials. In connection with its retention by TMBR/Sharp, D.F. King & Co., Inc. has agreed to provide consulting and analytic services and provide solicitation services with respect to banks, brokers, institutional investors and individual shareholders. TMBR/Sharp agreed to pay D.F. King & Co., Inc. a fee of $7,500 plus "broker bills," reasonable expenses, costs and disbursements, including reasonable counsel fees and expenses, and to indemnify D.F. King & Co., Inc. against certain liabilities and expenses, including liabilities under the federal securities laws. In addition to the solicitation of proxies by mail, some of TMBR/Sharp's directors, officers and employees may solicit proxies by telephone, facsimile and personal contact, without separate compensation for those activities. Copies of solicitation materials will be furnished to fiduciaries, custodians and brokerage houses for forwarding to beneficial owners of TMBR/Sharp Shares, and these persons will be reimbursed for their reasonable out-of-pocket expenses. TMBR/Sharp does not intend to use the Internet to solicit proxies, but if the Internet is used for this purpose, TMBR/Sharp will file with the SEC as additional soliciting material any written material used for that purpose. QUORUM The presence at the special meeting of the holders of a majority of the outstanding TMBR/Sharp Shares entitled to vote, either in person or by proxy, is necessary to constitute a quorum to transact business at the special meeting. Abstentions and broker non-votes will be counted to determine whether or not there is a quorum at the special meeting. A broker non-vote occurs when a broker votes on some matters on the proxy card but not on others because he does not have the authority to vote on such other matters. MEETING PROPOSALS At the meeting, holders of TMBR/Sharp Shares will be asked to consider and vote on the merger proposal and the adjournment proposal. A vote for the merger proposal is not also a vote for the adjournment proposal. You must vote separately on each proposal. The affirmative vote of the holders of at least two-thirds of the outstanding TMBR/Sharp Shares entitled to vote at the special meeting is required to approve the merger proposal. The affirmative vote of the holders of a majority of TMBR/Sharp Shares present in person or by proxy at the special meeting is required to approve the adjournment proposal. Approval of the merger proposal will permit the merger of TMBR/Sharp with and into Sub in accordance with, and subject to, the terms and conditions of the merger agreement. Approval of the 14 adjournment proposal will permit the adjournment of the special meeting to solicit additional proxies if there are not sufficient votes at the time of the special meeting to approve the merger proposal. If on the date of the special meeting TMBR/Sharp has not received duly executed proxies which, when added to the number of votes represented in person at the special meeting by persons who intend to vote for the merger proposal, will constitute a sufficient number of votes to approve the merger proposal, TMBR/Sharp may recommend the adjournment of the special meeting to a date not later than , 2003 if the adjournment proposal is approved. Thomas C. Brown and David N. Fitzgerald, the persons appointed as proxy for the special meeting, in consultation with D.F. King & Co., Inc., will determine if the special meeting will be adjourned to permit further solicitation and for how many days to a date not later than , 2003, based on their estimate of how many days may be needed for further solicitation. However, if holders of TMBR/Sharp Shares holding greater than one-third of the outstanding TMBR/Sharp Shares have indicated their intention to vote against, and have submitted duly executed proxies voting against, the merger proposal, TMBR/Sharp will hold the vote on the merger proposal and will not recommend adjournment of the meeting. Approval of the adjournment proposal by the holders of TMBR/Sharp Shares is not a condition to the merger. VOTING HOW TO VOTE YOUR SHARES Each TMBR/Sharp Share is entitled to one vote. If you are a record holder of TMBR/Sharp Shares, you may vote your TMBR/Sharp Shares at the special meeting in person or by proxy. To vote in person, you must attend the special meeting, and obtain and submit a ballot. The ballot will be provided at the special meeting. To vote by proxy, you must complete and return the enclosed proxy card. The proxy card contains specific instructions on how to complete it. By completing and submitting it, you will direct the designated persons (known as "proxies") to vote your TMBR/Sharp Shares at the special meeting in accordance with your instructions. The TMBR/Sharp board has appointed Thomas C. Brown and David N. Fitzgerald to serve as proxies for the meeting. Your proxy will be valid only if you sign, date and return it before the special meeting. If you complete all of the proxy card except the voting instructions, the designated proxies will vote your shares FOR the approval of the merger agreement and FOR the adjournment proposal. You may revoke your proxy at any time before it is exercised (i.e., before the voting begins) by any one of the following means: - notifying TMBR/Sharp's secretary in writing; - submitting another proxy bearing a later date; or - attending the special meeting and voting in person. Your attendance at the special meeting will not by itself revoke a proxy; you must vote your shares at the meeting to revoke your proxy. If you choose to submit a notice of revocation or a new proxy card you must send it to the Secretary of TMBR/Sharp at 4607 West Industrial Blvd., Midland, Texas 79703. TMBR/Sharp must receive the notice or new proxy card before the vote is taken at the special meeting. Many of TMBR/Sharp's shareholders hold their TMBR/Sharp Shares in "street name." "Street name" means that the shares are registered in the names of their broker, bank or other nominee holder rather than in the shareholders' names. In addition to the proxy solicitation materials TMBR/Sharp has provided to the street name holder, the street name holder should provide to you the street name holder's own request for voting instructions. By completing the voting instruction card, you may direct your street name holder how to vote your shares. Alternatively, if you want to vote your street name shares at the special meeting, you must contact your broker directly in order to obtain a proxy issued to you by your broker as the nominee holder. NOTE THAT A BROKER LETTER THAT IDENTIFIES YOU AS A SHAREHOLDER IS NOT THE SAME AS A NOMINEE-ISSUED PROXY. If you fail to bring a nominee-issued proxy to the special meeting, you will not be able to vote your street name shares at the special meeting. 15 Your TMBR/Sharp Shares will be voted for or against the merger proposal and for or against the adjournment proposal only if you provide written instructions to your broker as to how to vote your shares. If you want your broker to vote your shares in favor of the merger proposal and the adjournment proposal, you should follow the directions provided by your broker regarding how to instruct your broker to vote your shares. Without instructions, your shares will not be voted by your broker and the failure to vote will have the same effect as a vote AGAINST the approval of the merger agreement but, assuming a quorum is present at the special meeting, will have no effect on the adjournment proposal. EFFECT OF FAILURE TO VOTE, ABSTENTIONS AND BROKER NON-VOTES The failure to return a properly executed proxy card or to vote at the special meeting will have the same effect as a vote against the approval of the merger agreement but, assuming a quorum is present at the special meeting, will have no effect on the approval of the adjournment proposal. An abstention from the vote to approve the merger agreement will have the same effect as a vote against the approval of the merger agreement and against the adjournment proposal. If your TMBR/Sharp Shares are held in "street name" by your broker or are held in the name of some other nominee holder, your shares will be voted for or against the approval of the merger agreement and for or against the adjournment proposal only if you provide written instructions to your broker as to how to vote your shares. If you fail to provide voting instructions to your broker or nominee holder, such broker non-votes will have the same effect as a vote against the approval of the merger agreement but, assuming a quorum is present at the special meeting, will have no effect on the approval of the adjournment proposal. APPRAISAL RIGHTS TMBR/Sharp shareholders who do not vote in favor of approval of the merger agreement and who otherwise comply with the applicable statutory procedures of the TBCA summarized elsewhere in this proxy statement/prospectus, will be entitled to seek appraisal of the value of their TMBR/Sharp Shares under Articles 5.11-5.13 of the TBCA. See "The Merger -- Dissenters' Rights of Appraisal" on page 42. STOCK CERTIFICATES PLEASE DO NOT SEND YOUR STOCK CERTIFICATES AT THIS TIME. IF THE MERGER IS COMPLETED, PATTERSON-UTI WILL SEND YOU INSTRUCTIONS REGARDING THE PROCEDURES FOR CONVERSION OF EACH OF YOUR TMBR/SHARP SHARES INTO THE RIGHT TO RECEIVE $9.09 IN CASH AND 0.312166 OF A PATTERSON-UTI SHARE. 16 THE MERGER BACKGROUND OF THE MERGER During the last few years, in an effort to maximize shareholder value, TMBR/Sharp's board of directors periodically reviewed and evaluated TMBR/Sharp's presence and position in its areas of operation. During this time, the TMBR/Sharp board of directors monitored the size and quality of TMBR/Sharp's rig fleet, the quality of its crews, the type of rigs preferred by its customers and potential customers, rig utilization rates and the benefits that might be achieved by acquiring additional rigs and expanding TMBR/Sharp's geographic areas of operation. Also during this time, TMBR/Sharp discussed at different times with one privately owned company and three publicly owned companies, including Patterson-UTI, the possibility of entering into different types of business combinations. Although initially focused on expansion, the TMBR/Sharp board of directors gradually broadened its focus to include the possibility of being acquired. This transition resulted from a number of factors, including periods of depressed industry conditions, increased competition resulting from the consolidation of TMBR/Sharp's competitors into larger companies with greater resources, the indications of interest received by TMBR/Sharp from potential purchasers as discussed below, and, to a lesser extent, the death in January 2001 of Joe G. Roper, a founder and former director and president of TMBR/Sharp. TMBR/Sharp's familiarity with Patterson-UTI, its predecessors and their respective principals, including Cloyce A. Talbott and A. Glenn Patterson, Patterson-UTI's current chief executive officer and president, respectively, dates back many years. TMBR/Sharp and its former parent, Tom Brown, Inc., have competed with Patterson-UTI in the contract drilling business since the formation of Patterson Energy, Inc., the predecessor of Patterson-UTI, in 1978. The proximity of the two companies' headquarters, which are approximately 100 miles apart, has resulted in the companies competing in many local markets and serving the same customers from time to time. As in any business, these competitors have closely monitored one another's businesses for many years. Additionally, Mark S. Siegel, the chairman of the board of directors of Patterson-UTI, and Mr. Brown had brief, informal conversations from time to time regarding interest in a business combination, beginning as early as 1996 when Mr. Siegel was chairman of the board of UTI Energy Corp., an independent onshore contract drilling company, before its merger with Patterson Energy, Inc. in May 2001. In June 2001, TMBR/Sharp commenced its consideration and evaluation of the acquisition of a privately held drilling company operating land drilling rigs in Texas. Eventually, TMBR/Sharp's board of directors concluded not to proceed with the acquisition. However, TMBR/Sharp's board of directors continued to discuss different ways to acquire additional rigs from other third parties, including an acquisition of another drilling company. The first publicly owned drilling company to make a written proposal to acquire TMBR/Sharp came in January 2002. Mr. Brown received a letter dated January 18, 2002 from the chairman of the board and chief executive officer of this first company, which included a proposal to acquire all of TMBR/Sharp's Shares at $15.00 per share, payable in cash, stock or a combination of cash and stock. The $15.00 price per share represented a premium of approximately 15.4% over the closing price of $13.00 per share on January 18, 2002. At a meeting of TMBR/Sharp's board of directors on January 22, 2002, the directors reviewed and discussed the proposal. After discussion, the TMBR/Sharp board of directors authorized Mr. Brown to find and engage an investment banking firm. Mr. Brown discussed with an investment banking firm the possibility of entering into a financial advisory services agreement and the general terms of an agreement. However, after further discussions between Mr. Brown, Jeffrey D. Phillips, the president of TMBR/Sharp, and this first publicly owned company, the prospects of a transaction between the two companies became increasingly remote. As a result, and to avoid payment of unnecessary engagement or retainer fees, TMBR/Sharp did not engage an investment banking firm until November 2002, when discussions regarding a potential transaction advanced to a point that justified engaging an investment banking firm. In addition, and further contributing to the delay of engaging an investment banking firm, on May 9, 2002, TMBR/Sharp experienced a well blowout 17 on a property believed by TMBR/Sharp to have potentially significant reserves. The engagement of an investment banking firm was further postponed until the well was brought under control and TMBR/Sharp could more accurately assess the potential impact of the well on its financial condition. In early March 2002, Patricia R. Elledge, TMBR/Sharp's controller and a daughter of Mr. Roper, received a telephone message from John E. Vollmer III, the Senior Vice President -- Corporate Development of Patterson-UTI. Upon returning the call, Ms. Elledge learned that Patterson-UTI was interested in acquiring the TMBR/Sharp Shares held by Mr. Roper's estate and by the Roper family. After becoming aware that Patterson-UTI was interested in acquiring the TMBR/Sharp Shares held by the Roper family, and during a telephone conversation between Mr. Brown and the chief executive officer of a third public company, Mr. Brown, a business partner of Joe G. Roper and close friend of his and his family for more than fifty years, commented to the chief executive officer that the Roper family was interested in selling its TMBR/Sharp Shares. Mr. Brown remarked that if the third company had an interest in acquiring the TMBR/Sharp Shares held by the Roper family, the chief executive officer might want to call the Roper family. Thereafter, and independently of any involvement of Mr. Brown or TMBR/Sharp, this third public company contacted a representative of the Roper family and pursued negotiations for the purchase of the Roper family's TMBR/Sharp Shares. On March 14, 2002, Mr. Brown received a letter from the chief executive officer of the third publicly owned drilling company expressing its willingness to acquire 1,079,000 TMBR/Sharp Shares held by the estate of Mr. Roper, the children of Mr. Roper and a family partnership controlled by them. The letter included a proposal to acquire these shares at a price of $15.05 per share, which represented a premium of approximately 13.7% over the closing price of $13.24 per share on March 14, 2002. The proposal to acquire the TMBR/Sharp Shares held by the Roper family and their affiliated entities was subject to certain conditions, including, among other things, TMBR/Sharp entering into a merger agreement with this third company and agreeing to either repurchase the Roper family's TMBR/Sharp Shares from that company at a price of $15.05 per share if the merger agreement was terminated or pay to that company the difference between the price the company sold such shares (if less than $15 per share) and the price paid by the company for such shares. Under the proposal, this third company would exchange 1.15 shares of its common stock for each outstanding TMBR/Sharp Share, resulting in a valuation of $17.56 per TMBR/Sharp Share. The TMBR/Sharp board of directors discussed a possible combination with that company and other strategies. On March 19, 2002, this third company requested copies of certain materials in order to conduct a due diligence review of TMBR/Sharp. At a meeting of TMBR/Sharp's board of directors on March 21, 2002, Mr. Brown reported on his conversations with the chief executive officer of the third company and advised the directors that he had informed the chief executive officer that the contingencies outlined in the proposal would not be acceptable to TMBR/Sharp. Mr. Brown concluded that the offer was not acceptable primarily because of his belief that (1) the two potential transactions among the parties should be pursued independently, if at all; (2) the terms of one transaction should not influence or dictate the terms of the other potential transaction; (3) TMBR/Sharp should not be required to repurchase the Roper family shares under any circumstances; and (4) this third company would not increase its offering price. Mr. Brown further advised the directors that this third company had contacted the Roper family for the purpose of negotiating the purchase of the Roper family's TMBR/Sharp Shares. The directors then entered into a general discussion regarding: - a potential combination of TMBR/Sharp with this third company and other possible companies; - the break-up value of the TMBR/Sharp Shares, estimated by TMBR/Sharp at that time to be $19.70 per share; - proposed exchange rates; - current oil and gas reserve values; - the value of TMBR/Sharp Shares and its price performance; 18 - the financial condition of other companies that might have an interest in a combination with TMBR/Sharp; - potential transactions with other companies, including Patterson-UTI; and - the impact that a combination with this third company might have on TMBR/Sharp's oil and gas exploration and production activities. Based on the recommendation of Mr. Brown and the discussion described above among the directors, the directors deferred any formal action in respect of the third company's offer. On March 22, 2002, TMBR/Sharp and its legal advisors received unsolicited drafts of a proposed agreement and plan of merger from the third company. At a telephonic meeting of TMBR/Sharp's board of directors on May 21, 2002, the board again discussed the possibility of a transaction with the third company. Mr. Brown suggested that no action be taken until TMBR/Sharp had completed the redrilling of a well in Loving County, Texas that had experienced a blowout earlier in the month. After following up on earlier discussions, an agreement was never entered into because of differences in establishing a mutually acceptable price and Patterson-UTI's acquisition of TMBR/Sharp Shares from the Roper family as described below. After a series of discussions, certain members of the Roper family, Mr. Roper's estate and a Roper family partnership entered into a stock purchase agreement with Patterson-UTI on June 11, 2002, pursuant to which they sold to Patterson-UTI 762,597 TMBR/Sharp Shares at a price of $16.60 per share on June 14, 2002. The sellers also granted to Patterson-UTI an option to purchase, and Patterson-UTI granted the sellers an option to sell, an additional 195,000 TMBR/Sharp Shares at $16.60 per share. On June 12, 2002, Mr. Siegel called Mr. Brown and informed him about the transaction with the Roper family and that Patterson-UTI had purchased, or received an option to purchase, approximately 19.7% of the then outstanding TMBR/Sharp Shares. Mr. Siegel also informed Mr. Brown of the following matters: - the TMBR/Sharp Shares had been acquired for investment purposes; - Patterson-UTI was interested in possible strategic opportunities with TMBR/Sharp, including the possible combination of TMBR/Sharp and Patterson-UTI; - Patterson-UTI had indicated its interest to TMBR/Sharp; and - Patterson-UTI had no intention of pursuing a strategic transaction other than on a mutually acceptable basis. On June 12, 2002, Mr. Phillips distributed to TMBR/Sharp's board of directors copies of Patterson-UTI's press release relating to the transaction and a letter from Mr. Siegel to Mr. Brown restating matters discussed in the immediately preceding bullet points. At the July 18, 2002 meeting of Patterson-UTI's board of directors, Mr. Siegel reported on, and the directors discussed, strategic opportunities relating to TMBR/Sharp. At the August 28, 2002 meeting of TMBR/Sharp's board of directors, the directors reviewed and discussed TMBR/Sharp's future prospects, the advantages and disadvantages of pursuing a business combination and the need to engage an investment banking firm. The directors requested that Mr. Brown continue to explore potential combination transactions and proceed with the selection and engagement of an investment banking firm to serve as TMBR/Sharp's financial advisor in connection with strategic transactions. Following this meeting, Mr. Brown and Mr. Phillips had discussions from time to time with representatives of ECS regarding potential combination matters, such as potentially interested parties, timing and the type of transaction that might be suitable for TMBR/Sharp. Other than these discussions with ECS, there were no material developments regarding potential combinations involving TMBR/Sharp until November, 2002. 19 At the October 16, 2002 meeting of TMBR/Sharp's board of directors, the directors discussed the current status of the contract drilling markets generally, the financial condition of TMBR/Sharp and Patterson-UTI and the market price of Patterson-UTI Shares. The directors also discussed the exploration and production activities of Patterson-UTI. On October 28, 2002, Patterson-UTI entered into a stock purchase agreement with a member of the Roper family to purchase an additional 101,076 TMBR/Sharp Shares at a price of $16.60 per share. On October 29, 2002, Patterson-UTI completed the purchase of the 195,000 TMBR/Sharp Shares subject to the option granted pursuant to the June 11, 2002 stock purchase agreement and completed the purchase of 101,076 TMBR/Sharp Shares pursuant to the October 28, 2002 stock purchase agreement. In November 2002, TMBR/Sharp's compensation committee concluded that a bonus plan for certain key employees of TMBR/Sharp should be established. On November 6, 2002, the compensation committee met for the purpose of considering proposed bonus agreements for certain key employees that would provide an incentive for and encourage key employees to remain in TMBR/Sharp's employment during a period of uncertainty created by TMBR/Sharp's possible sale. After approval by, and upon recommendation of, the compensation committee, the TMBR/Sharp board of directors approved the final form of retention agreements for ten key employees. These agreements provide for the payment of a cash bonus following a merger in an amount equal to an employee's base salary times an applicable multiple. The maximum amount payable under the retention agreements is approximately $2,157,677. For a more complete description of the agreements, see "-- Interests of Certain Persons in the Merger -- Retention Agreements". On November 13, 2002, TMBR/Sharp entered into a financial advisory agreement with Energy Capital Solutions, LLC ("ECS") engaging ECS as TMBR/Sharp's exclusive financial advisor in connection with a transaction involving the direct or indirect sale or disposition of TMBR/Sharp. ECS was selected as TMBR/Sharp's financial advisor, in large part, because J. Russell Weinberg, a managing director of ECS, had performed financial services for TMBR/Sharp in the past, and because ECS is an investment banking firm whose principals have expertise and experience in transactions involving energy companies similar to TMBR/Sharp. In November 2002, and again in mid-January 2003, Patterson-UTI requested that TMBR/Sharp's board of directors adopt a resolution relating to Article 13.03 of the TBCA authorizing Patterson-UTI's purchase of a number of TMBR/Sharp Shares that would result in Patterson-UTI owning more than 20% of the outstanding TMBR/Sharp Shares. Under this statute, if any party acquires more than 20% of the outstanding TMBR/Sharp Shares without the prior approval of TMBR/Sharp's board of directors, that party cannot acquire or enter into certain transactions with TMBR/Sharp for a period of three years unless the acquisition is approved by two-thirds of the unaffiliated shareholders. Without advance approval of TMBR/Sharp's board of directors, these provisions of the TBCA could have delayed Patterson-UTI's ability to combine with TMBR/Sharp. TMBR/Sharp's board did not adopt the requested resolutions because of the uncertainties associated with a single party having ownership of such a large percentage of the outstanding TMBR/Sharp Shares, TMBR/Sharp's absence of any takeover defenses and the expressed interest of other companies in acquiring TMBR/Sharp. Throughout the latter part of 2002 and continuing into early February 2003, Mr. Brown and Mr. Siegel continued to discuss strategic opportunities, including a possible combination of TMBR/Sharp and Patterson-UTI on a mutually acceptable basis. At a meeting of Patterson-UTI's board of directors on February 4, 2003, Mr. Siegel reported on, and the directors discussed, acquisition opportunities relating to TMBR/Sharp. At a meeting of TMBR/Sharp's board of directors on February 11, 2003, the directors discussed the possible acquisition of TMBR/Sharp by Patterson-UTI and whether the consideration to TMBR/Sharp's shareholders in a potential transaction with Patterson-UTI should be all cash, all stock or a combination of cash and stock. The directors also discussed the implications of giving advance approval of Patterson-UTI's previous requests to acquire over 20% of the outstanding TMBR/Sharp Shares. Mr. Brown further 20 reported that ECS had remained in contact with the third public company that made an offer to TMBR/Sharp, and had gathered information regarding other companies that might be interested in acquiring TMBR/Sharp. Mr. Phillips also reported to the directors that the evaluation material requested by Patterson-UTI had been provided. These materials included oil and gas reserve data and other customary due diligence information. At the February 26, 2003 meeting of TMBR/Sharp's board of directors, ECS made a presentation to the directors of its preliminary valuation analysis of TMBR/Sharp, which showed a possible valuation range of $16.24 to $20.96 per share. ECS also provided information regarding potential buyers. TMBR/ Sharp's legal advisors also made a presentation regarding the fiduciary duties of directors and anti-takeover provisions for consideration by the directors. During this meeting, the directors asked ECS to call Mr. Siegel. ECS and Mr. Phillips then contacted Mr. Siegel to inquire about Patterson-UTI's interest in pursuing discussions of a possible merger of the two companies. On March 3, 2003, ECS, Mr. Brown and Mr. Phillips called Mr. Siegel and Kenneth N. Berns, a director of Patterson-UTI. In this conversation, ECS summarized the prior week's activities of TMBR/ Sharp and the parties discussed how best to proceed in evaluating the potential benefits of a mutually acceptable transaction, the manner in which a possible transaction might be achieved and the status of new wells being drilled by TMBR/Sharp. The parties agreed that detailed discussions, including pricing terms, would occur at a later date and that the primary communications and negotiations between the two companies would be conducted by designated representatives of each company. Thereafter, negotiations between the companies were conducted by ECS, on behalf of TMBR/Sharp, and by Mr. Berns, on behalf of Patterson-UTI. On March 7, 2003, Mr. Berns and Mr. Vollmer met with ECS to discuss initial due diligence matters and to gather more information about whether the parties should continue to consider exploring a possible combination on a mutually acceptable basis. Subsequent to these conversations, and through May 26, 2003, Patterson-UTI and its advisors conducted a due diligence review of TMBR/Sharp, which included, among other things, the evaluation of TMBR/Sharp's periodic reports filed with the SEC and other publicly available information, field inspections and the review of TMBR/Sharp's oil and gas reserve information and other legal, financial and operational documents. Throughout this time, discussions between ECS and the representatives of Patterson-UTI continued regarding the possibility of a merger and establishing a range of values that could be submitted to TMBR/Sharp's board of directors. On May 19, 2003, ECS received a telephone call from Mr. Berns in which Mr. Berns informed ECS that Patterson-UTI would consider offering $20.00 per share for the TMBR/Sharp Shares, which would be paid 50% in cash and 50% in Patterson-UTI Shares. At a telephonic meeting of TMBR/Sharp's board of directors on May 20, 2003, which was also attended by TMBR/Sharp's legal and financial advisors, ECS reported that the potential price to be offered by Patterson-UTI for the TMBR/Sharp Shares would be $20.00 per share, payable 50% in cash and 50% in Patterson-UTI Shares. The directors discussed: - seeking a higher valuation from Patterson-UTI; - contacting other potential buyers and the likelihood of being able to complete a transaction with other potential buyers in a timely manner; - fiduciary duties of the directors and the procedures required to meet these duties; - whether Patterson-UTI would be willing to reconsider its potential valuation of the outstanding TMBR/Sharp Shares; - the need to conduct further market checks in light of the board's prior discussions; - the advice of ECS regarding potential combinations; 21 - lock-up arrangements and the effect that different lock-up arrangements might have on a merger price; - the timing of a transaction with potential buyers; - the adequacy of the potential price to be offered by Patterson-UTI; - Patterson-UTI's identity in the marketplace; - current market conditions, including the value of TMBR/Sharp's drilling rigs; and - the advisability of contacting the third publicly owned company that had previously made a proposal to TMBR/Sharp and the risk of losing a potential transaction with Patterson-UTI. As a result of the discussion described above, at the request of the directors and during the meeting, ECS called Mr. Berns and advised him that TMBR/Sharp's board believed that the price should be greater than $20.00 per share. On May 21, 2003, Mr. Berns telephoned ECS and informed ECS that Patterson-UTI was willing to increase its potential valuation of the outstanding TMBR/Sharp Shares from $20.00 to $20.25 per share. At a telephonic meeting of TMBR/Sharp's board of directors on May 22, 2003, which was also attended by TMBR/Sharp's legal and financial advisors, ECS reported to the directors that Patterson-UTI was willing to increase its potential valuation of TMBR/Sharp from $20.00 per share to $20.25 per share. The directors discussed available alternatives, including contacting one of the other public companies that had expressed interest in pursuing a transaction with TMBR/Sharp. Having previously been informed by Raymond C. Batchelor, one of TMBR/Sharp's directors, that Mr. Batchelor and the chief executive officer of the third company coincidentally attended the same business luncheon in early May 2003, Mr. Brown reported that the chief executive officer of the third company informally commented that if TMBR/Sharp completed a transaction with Patterson-UTI, the third company would have an interest in acquiring TMBR/Sharp's oil and gas properties from Patterson-UTI. The directors discussed these comments and Mr. Brown reported that this third company had already contacted Patterson-UTI to express an interest in buying the properties from Patterson-UTI if Patterson-UTI and TMBR/Sharp completed a transaction. The directors also discussed the potential advantages and disadvantages of conducting further market checks. At the request of TMBR/Sharp's directors, Mr. Weinberg called Mr. Berns during the meeting to communicate an interest in pursuing a potential transaction and to discuss the process of how to proceed with further negotiations if Patterson-UTI had an interest in pursuing a potential transaction. Mr. Weinberg also inquired as to Patterson-UTI's position with respect to TMBR/Sharp contacting the third publicly owned company. Mr. Berns indicated he would have to call back after talking to Patterson-UTI's management. The TMBR/Sharp board of directors continued to discuss the structure of the acquisition and possible terms of the deal. On May 22, 2003, Mr. Berns returned the call to ECS and further discussed with ECS the process of pursuing negotiations. During the discussion, and in response to Mr. Berns' indication that Patterson-UTI preferred that TMBR/Sharp not contact other companies, Mr. Weinberg advised Mr. Berns that TMBR/Sharp would not contact other third parties, so long as the merger agreement did not contain any significant barriers to third party offers. Having previously reviewed and considered potential transactions with other third parties, and having further reviewed the group of potential third parties that might have an interest in a transaction with TMBR/Sharp, the TMBR/Sharp board of directors decided not to contact other third parties because of (1) its determination that the likelihood of entering into an alternative transaction with another company on acceptable terms was remote; (2) Patterson-UTI's expressed preference that TMBR/Sharp not contact other bidders, in exchange for which TMBR/Sharp required minimal barriers to third party offers; and (3) the belief that other potential candidates for a transaction would not be able to proceed as rapidly as Patterson-UTI, especially in view of Patterson-UTI's ownership position in TMBR/Sharp and familiarity with TMBR/Sharp. On May 23, 2003, TMBR/Sharp and its legal and financial advisors received an initial draft merger agreement. 22 Commencing on May 23, 2003 and continuing through May 26, 2003, representatives of TMBR/Sharp and Patterson-UTI, together with their respective advisors, engaged in extensive negotiations regarding the merger agreement and the terms of the proposed merger. On May 25, 2003, Mr. Brown, Mr. Phillips and representatives of ECS called Mr. Siegel, Mr. Vollmer and Mr. Jonathan D. Nelson, the Vice President-Finance, Chief Financial Officer, Secretary and Treasurer of Patterson-UTI, for the purpose of allowing ECS and TMBR/Sharp to complete their due diligence review of Patterson-UTI, and allowing Patterson-UTI to complete its due diligence review of TMBR/Sharp. On the evening of May 25, 2003 and the morning of May 26, 2003, summaries of the potential terms and provisions of the merger agreement and drafts of the merger agreement were distributed to TMBR/Sharp's board of directors. At 3:00 p.m. on May 26, 2003, TMBR/Sharp's board of directors convened for the purpose of considering and voting upon the proposed merger. At the meeting, members of TMBR/Sharp's senior management and TMBR/Sharp's legal and financial advisors reviewed with the board of directors the terms of the proposed merger. In particular, the TMBR/Sharp legal advisors advised the TMBR/Sharp board of directors as to its fiduciary duties to TMBR/Sharp shareholders. ECS then made a presentation regarding the analysis described under "-- Opinion of TMBR/Sharp's Financial Advisor". In addition, the terms of the merger agreement, including the conditions to closing and the termination fee, and related exhibits were presented in detail by the legal and financial advisors and were discussed at length with the board of directors. The potential benefits of the proposed merger and the financial and other effects the proposed merger would have on TMBR/Sharp and its shareholders were also discussed in detail by TMBR/Sharp's board of directors. Following further discussions between TMBR/Sharp and Patterson-UTI and their advisors, the remaining issues were resolved, including the allocation of cash and stock consideration and due diligence issues, which resulted in a reduction of the price offered by Patterson-UTI for each TMBR/Sharp Share from $20.25 to $20.20. The cash and stock offer of $20.20 represented a premium of approximately 4.12%, based on the closing prices of $19.40 per TMBR/Sharp Share and $35.59 per Patterson-UTI Share on May 23, 2003, the last trading day prior to the offer. After these discussions, ECS rendered its oral opinion, subject to TMBR/Sharp's receipt of the final written price of the merger consideration orally agreed upon by TMBR/Sharp and Patterson-UTI, that, as of the date and subject to various assumptions, the consideration to be received by TMBR/Sharp's shareholders in the merger was fair, from a financial point of view, to TMBR/Sharp's shareholders. Following receipt of the final written terms of the merger consideration, ECS confirmed its opinion in writing. After these presentations and discussions, and subject to receipt of the final written terms of the merger consideration, the board of directors of TMBR/Sharp unanimously agreed that the merger agreement and the merger were fair to, advisable and in the best interests of TMBR/Sharp and its shareholders and unanimously voted: (1) to approve and adopt the merger agreement and the transactions contemplated by the merger agreement, including the merger; and (2) to recommend that TMBR/Sharp's shareholders vote to approve and adopt the merger agreement and approve the merger. On the afternoon of May 26, 2003, a summary of the proposed terms and provisions of the merger agreement, the latest draft of the merger agreement and a financial analysis of the proposed merger prepared by the senior management of Patterson-UTI were distributed to Patterson-UTI's board of directors. At 6:00 p.m. on May 26, 2003, Patterson-UTI's board of directors convened for the purpose of considering and voting upon the proposed merger. At the meeting, members of Patterson-UTI's senior management and Patterson-UTI's legal advisors reviewed with the board of directors the terms of the merger and a financial analysis of the proposed merger. In particular, Mr. Siegel summarized the chronology of events leading up to the recent negotiations, including Patterson-UTI's previous acquisition of nearly 20% of the outstanding TMBR/Sharp Shares. Mr. Berns presented in detail the terms of the merger agreement, including, among other things, the representations and warranties to be made by TMBR/Sharp, the conditions to closing, the termination provisions, the break-up fee and the treatment of 23 TMBR/Sharp stock options. Mr. Talbott reported on the TMBR/Sharp exploration and production assets. Another member of senior management informed the directors of the results of due diligence on TMBR/Sharp and presented in detail the financial analysis of the proposed transaction, including the allocation of the cash and stock consideration and the valuation of the TMBR/Sharp Shares at a price of $20.20 per share. The Patterson-UTI board of directors discussed the terms of the merger agreement, the financial analysis and the due diligence results at length and asked senior management questions related to those matters, including among other things, the potential tax consequences of the proposed merger and the assumptions used in the senior management's financial analysis. The Patterson-UTI board of directors also discussed the potential benefits of the proposed merger and the financial and other effects that the proposed merger would have on Patterson-UTI and its stockholders. At approximately 7:30 p.m., after these presentations and discussions, the board of directors of Patterson-UTI unanimously agreed that the merger agreement and the merger were fair to, advisable and in the best interests of Patterson-UTI and its stockholders and unanimously voted to approve and adopt the merger agreement and the transactions contemplated by the merger agreement, including the merger. On May 26, 2003, Patterson-UTI, Sub and TMBR/Sharp executed the merger agreement and on May 27, 2003, issued a joint press release announcing that the parties had signed a merger agreement. As of the date of this proxy statement/prospectus, TMBR/Sharp has not received any expression of interest from other third parties about alternate transactions. TMBR/SHARP'S REASONS FOR THE MERGER The TMBR/Sharp board of directors determined that the proposed merger is in the best interests of TMBR/Sharp and its shareholders because it believes that the value of the cash and stock consideration in the combined company after the merger is likely to be superior to the long term value of an investment in TMBR/Sharp as a stand-alone company. The TMBR/Sharp board considers the merger to be a means of achieving the long term strategic and financial goals of TMBR/Sharp while at the same time offering the TMBR/Sharp shareholders the ability to participate in a larger, more diversified company. The decision of the TMBR/Sharp board to approve the merger agreement and to recommend its adoption by TMBR/Sharp's shareholders was based upon various factors, including those mentioned in "-- Background of the Merger" beginning on page 17, and the following: - the judgment, advice and analyses of senior management of TMBR/Sharp, including their analysis of the domestic onshore drilling and oil and gas exploration and production industries generally and the strategic options available to TMBR/Sharp; - the value of the cash and stock consideration offered in the merger in relation to historical and current market trading prices for TMBR/Sharp Shares and the underlying value of TMBR/Sharp's net assets; - information concerning the historical financial performance and condition, business operations and prospects of each of TMBR/Sharp and Patterson-UTI; - TMBR/Sharp's projected future performance and prospects as a separate entity and on a combined basis with Patterson-UTI; - the operational efficiencies and collective management experience that would result from the merger; - the fact that the size and importance in the drilling industry of the combined companies would likely provide greater visibility and a stronger following by research analysts and greater stock market liquidity than TMBR/Sharp would have on its own; - the structure of the transaction and the terms of the merger agreement; - the fact that the merger would provide holders of TMBR/Sharp Shares with the opportunity to receive a premium over recent market prices for TMBR/Sharp Shares and a more actively traded stock; 24 - the provisions of the merger agreement that permit the TMBR/Sharp board, in the exercise of its fiduciary duties, to terminate the merger agreement upon the payment of a $3.5 million termination fee to Patterson-UTI under certain circumstances if a higher offer for TMBR/Sharp is made, coupled with the fact that the TMBR/Sharp board did not view this termination fee as unreasonably deterring any seriously interested third party from making a higher offer; - the opinion of TMBR/Sharp's financial advisor, as described below under "-- Opinion of TMBR/Sharp's Financial Advisor", that the consideration to be received by holders of TMBR/Sharp Shares in the merger was fair from a financial point of view to such holders; - the historical performance and financial strength of Patterson-UTI; - the likelihood that the merger will be consummated; - the belief that TMBR/Sharp will be able to continue its business activities without any major disruption to its customers; and - the belief of an increase in access to capital markets. All of the above factors supported the TMBR/Sharp board's decision to approve the merger agreement and the merger. In reaching its decision to approve the merger agreement and the merger and to recommend the adoption of the merger agreement by the TMBR/Sharp shareholders, the TMBR/Sharp board did not view any single factor as determinative, and did not find it necessary or practicable to assign any relative or specific weights to the various factors considered. Furthermore, individual directors may have given different weights to different factors. The potential risks and disadvantages to the merger that were identified by TMBR/Sharp's board as material included the following: - the process of effecting the merger will require TMBR/Sharp's management to divert a significant amount of their time and resources from daily operations, and will involve significant expenses payable to legal, accounting and other financial professionals, even if the merger is not completed; - the integration of the operations and systems of Patterson-UTI and TMBR/Sharp may involve unforeseen difficulties and fail to achieve the cost savings and other benefits anticipated by the parties; - the larger combined company may not be able to focus on the exploration and production of TMBR/Sharp's oil and natural gas reserves in the same manner as TMBR/Sharp has done in the past; - the market price of Patterson-UTI Shares at the time of the merger may be lower than the market price of the Patterson-UTI Shares when the merger agreement was signed, and lower than the corresponding market price on the date of this proxy statement/prospectus or the date of the special meeting; - the merger might not be completed as a result of a failure to satisfy the conditions contained in the merger agreement or other reasons; - the merger might result in the loss of jobs of TMBR/Sharp employees; and - the share price of the larger combined company might not be as favorably affected by the exploration and production segment of TMBR/Sharp's business as the price of the TMBR/Sharp Shares before the merger. For additional discussion of the risks associated with the merger, see "Risk Factors" beginning on page 10. 25 RECOMMENDATIONS OF TMBR/SHARP'S BOARD OF DIRECTORS FOR THE REASONS SET FORTH UNDER "-- BACKGROUND OF THE MERGER" AND "-- TMBR/SHARP'S REASONS FOR THE MERGER," TMBR/SHARP'S BOARD OF DIRECTORS HAS UNANIMOUSLY DETERMINED THAT THE MERGER IS FAIR TO, ADVISABLE AND IN THE BEST INTERESTS OF TMBR/SHARP AND ITS SHAREHOLDERS. TMBR/SHARP'S BOARD OF DIRECTORS UNANIMOUSLY RECOMMENDS THAT TMBR/SHARP SHAREHOLDERS APPROVE THE MERGER AND MERGER AGREEMENT. In addition to consideration to be received for their TMBR/Sharp Shares, eight officers and directors of TMBR/Sharp will receive compensatory payments as a result of the merger. You should consider these payments and certain other interests in voting on the merger. For additional information regarding these interests, see "-- Interests of Certain Persons in the Merger" beginning on page 37. OPINION OF TMBR/SHARP'S FINANCIAL ADVISOR TMBR/Sharp engaged ECS as its financial advisor on November 13, 2002, in connection with a possible merger or business combination involving TMBR/Sharp. On May 26, 2003, ECS rendered to the TMBR/Sharp Board of Directors its oral opinion (followed by its written opinion as of the same date) that, as of that date and based upon and subject to the assumptions and qualifications described in such opinion, the consideration described in the draft merger agreement, dated May 26, 2003, to be received by the holders of TMBR/Sharp Shares (other than Patterson-UTI and TMBR/Sharp) in the merger was fair from a financial point of view to such holders. The amount of consideration to be paid in the merger was not determined by ECS but was determined through negotiations between TMBR/Sharp and Patterson-UTI. The discussion below is a description of the assumptions made, procedures followed, matters considered and limits of the scope of review undertaken by ECS in rendering its opinion, which is attached as Annex B to this proxy statement/prospectus and is incorporated by reference in this document. TMBR/Sharp shareholders are urged to read carefully the ECS opinion. The full text of ECS' opinion is also available for inspection and copying at TMBR/Sharp's corporate offices during regular business hours by any of TMBR/Sharp's shareholders, or a shareholder's representative who has been so designated in writing. ECS' opinion was provided to the TMBR/Sharp board of directors for its use and benefit and addresses only the fairness from a financial point of view of the consideration to be received by the holders of TMBR/Sharp Shares. ECS' opinion does not address the merits of the underlying decision by TMBR/Sharp to engage in the merger and does not constitute a recommendation to any shareholder as to how that shareholder should vote at the special meeting. ECS' opinion and its presentation to the TMBR/Sharp board of directors on May 26, 2003 were among many factors taken into consideration by the TMBR/Sharp board of directors in making its determination to approve and recommend the merger. In arriving at its opinion, ECS, among other things: - reviewed certain publicly available business and financial information relating to TMBR/Sharp, including its Annual Reports on Form 10-K and related audited financial statements for the fiscal years ended March 31, 2000, March 31, 2001 and March 31, 2002; - reviewed a draft dated May 2, 2003, of TMBR/Sharp's unaudited financial statements for the fiscal year ended March 31, 2003; - reviewed certain publicly available business and financial information relating to Patterson-UTI, including its Annual Reports on Form 10-K and related audited financial statements for the fiscal years ended December 31, 2000, December 31, 2001 and December 31, 2002, and its unaudited financial statements on Form 10-Q for the fiscal quarters ended March 31, 2002 and March 31, 2003; - reviewed certain estimates of TMBR/Sharp's oil and gas reserves, including estimates of proved, probable and possible reserves prepared by Joe C. Neal & Associates as of April 1, 2003; - analyzed certain historical and projected financial and operating data of TMBR/Sharp; 26 - reviewed certain estimates of TMBR/Sharp's yard inventory and other equipment related to the drilling business as prepared by the management of TMBR/Sharp; - reviewed certain research reports relating to the historical and projected financial and operating data of Patterson-UTI prepared by third-parties; - discussed the current operations and prospects of TMBR/Sharp and Patterson-UTI with the management and staff of TMBR/Sharp and Patterson-UTI, respectively; - reviewed the historical market prices and trading history of the TMBR/Sharp Shares and the Patterson-UTI Shares; - compared recent stock market capitalization indicators for TMBR/Sharp with recent stock market capitalization indicators for certain other publicly traded independent energy and land drilling companies; - compared the financial terms of the merger with the financial terms of other transactions that ECS deemed to be relevant; - participated in certain discussions among representatives of TMBR/Sharp and Patterson-UTI and their respective advisors; - reviewed the merger agreement dated May 26, 2003; and - reviewed such other financial studies and analyses and performed such other investigations and considered such other matters as ECS deemed necessary or appropriate. In preparing its opinion, ECS assumed and relied upon, without assuming any responsibility for or independently verifying, the accuracy and completeness of any information supplied or otherwise made available to ECS by TMBR/Sharp and Patterson-UTI. ECS further relied upon the assurances of the representatives of the management of TMBR/Sharp and Patterson-UTI that they were unaware of any facts that would make the information provided to ECS incomplete or misleading in any material respect. With respect to projected financial and operating data, ECS assumed that the data had been reasonably prepared on bases reflecting the best currently available estimates and judgments of the management and staff of TMBR/Sharp relating to the future financial and operational performance of TMBR/Sharp. With respect to the estimates of oil and gas reserves, ECS assumed that they had been reasonably prepared on bases reflecting the best currently available estimates and judgments of the management and staff of TMBR/Sharp (and its engineering consultants) relating to the oil and gas properties of TMBR/Sharp. ECS did not make an independent evaluation or appraisal of the assets or liabilities of either TMBR/Sharp or Patterson-UTI nor, except for the estimates of oil and gas reserves and estimates of drilling equipment and yard inventory referred to above, was ECS furnished with any such evaluations or appraisals. In addition, ECS did not assume any obligation to conduct, and did not conduct, any physical inspection of the properties or facilities of TMBR/Sharp or Patterson-UTI. ECS was not asked to consider, and its opinion does not address, the price at which Patterson-UTI Shares or TMBR/Sharp Shares will trade following the announcement of the merger or the price at which the Patterson-UTI Shares will trade following the consummation of the merger. ECS' opinion was rendered on the basis of conditions in the securities markets and the oil and gas markets prevailing as of the date of its opinion and the condition and prospects, financial and otherwise, of TMBR/Sharp and Patterson-UTI as they had been represented to ECS as of the date of its opinion or as they were reflected in the materials and discussions described above. The following is a summary of the analyses performed by ECS in connection with the preparation of its opinion dated May 26, 2003, and presented to the TMBR/Sharp Board of Directors on that date. This summary includes information presented in tabular format. In order to fully understand these financial analyses, the tables must be read carefully together with the text accompanying each summary. The tables alone do not constitute a complete description of these financial analyses. Considering the data 27 set forth in the tables without considering the full narrative description of these analyses, including the methodologies and assumptions underlying these analyses, could create a misleading or incomplete view of the financial analyses performed by ECS. SUMMARY OF ANALYSIS The following table sets forth the summary results of the material valuation methodologies utilized by ECS as part of its analysis:

HISTORICAL STOCK TRADING RATIO ANALYSIS ECS analyzed the historical ratios of the closing prices of TMBR/Sharp Shares divided by corresponding closing prices of Patterson-UTI Shares for the period from May 24, 2002 to May 23, 2003. ECS noted the proposed merger exchange ratio of 0.568 was above the average historical trading ratio of 0.535 during such period. Additionally, ECS noted that the proposed merger exchange ratio was also above the three month average historical trading ratio of 0.546, the six month average historical trading ratio of 0.541, and the historical trading ratio of 0.538 from June 12, 2002, the date Patterson-UTI first announced it would acquire a portion of TMBR/Sharp Shares. IMPLIED PREMIUM ANALYSIS ECS calculated the premiums implied by comparing the $20.20 per share merger consideration for the TMBR/Sharp Shares in blended value offered by Patterson-UTI (based on the closing price of Patterson-UTI Shares on May 23, 2003) to the average historical trading price of TMBR/Sharp Shares for specified periods between May 23, 2002 and May 23, 2003, and between June 12, 2001 and June 12, 28 2002 (the date Patterson-UTI publicly announced its initial acquisition of TMBR/Sharp Shares), and derived the following results:
TMBR/SHARP $20.20 OFFER AVERAGE PRICE PREMIUM ----------------- ----------------- PERIOD 6/12/02 5/23/03 6/12/02 5/23/03 ------ ------- ------- ------- ------- Last Price........................................ $15.75 $19.40 28% 4% Day Prior......................................... $13.92 $19.51 45% 4% 30 days........................................... $15.29 $17.00 32% 19% 60 days........................................... $13.70 $17.47 47% 16% 90 days........................................... $12.15 $16.40 66% 23% 180 days.......................................... $12.80 $12.36 58% 63% 1 year............................................ $10.25 $13.45 97% 50% 52-Week High Price................................ $20.30 0% 52-Week Low Price................................. $12.05 68%
NET ASSET VALUE ANALYSIS ECS conducted a net asset value analysis for the purpose of determining the equity reference value range per share of TMBR/Sharp Shares. ECS calculated the net present value of estimates of future after-tax cash flows for TMBR/Sharp's oil and gas reserve assets based on the proved, probable and possible reserve estimates referred to above, for its drilling assets using the reference value range from selected comparable drilling asset transactions (as described in Selected Comparable Asset Transactions Analysis below), and for its other non-reserve assets utilizing information provided by TMBR/Sharp. For the oil and gas assets, ECS evaluated three scenarios in which the principal variables were oil and gas prices. The three pricing scenarios, 5-Year Strip Average, Strip Flat, and 5-Year Historical Flat, were based on benchmarks for spot sales of West Texas Intermediate crude oil and for spot sales of Henry Hub gas. The strip pricing scenarios were based upon the publicly available average of oil and gas futures contract prices quoted on the New York Mercantile Exchange (NYMEX) as of May 23, 2003. The 5-Year Strip Average Case utilized the average price of the NYMEX futures for oil and gas for the period May 23, 2003 to December 31, 2007. The Strip Flat Case reflected the average NYMEX futures price for each year, 2003 to 2007, for oil and gas prices. For the period April 1, 2003 through December 31, 2003, the 5-Year Strip Average Case and the Strip Flat Case reflected actual prices from April 1, 2003 through May 23, 2003, blended with the NYMEX strip for the remainder of the year. The 5 Year Historical Flat Case reflected the average price of oil and gas for the five-year period between May 26, 1998 and May 23, 2003, as the constant price for oil and gas. Adjustments were made to the benchmarks based on the historical relationship between the benchmarks and TMBR/Sharp's realized prices. Applying after-tax discount rates of 10.0%-12.5%, 12.5%-15.0%, 15.0%-20.0%, 30.0%-40.0% and 40.0%-50.0% for the proved producing, proved non-producing, proved undeveloped, probable and possible reserve categories, respectively, to the after-tax cash flows, assuming a carry-over of TMBR/Sharp's existing tax positions, and adding net working capital of $9.4 million as of March 31, 2003, the net asset value analysis indicated equity reference value ranges that were divided by the diluted number of shares of TMBR/Sharp Shares outstanding to derive the following equity reference value ranges per share of TMBR/Sharp Shares:
5-YEAR 5-YEAR STRIP AVERAGE STRIP FLAT HISTORICAL FLAT --------------- --------------- --------------- Equity Reference Value Range per Common Share....................... $17.35 - $19.92 $17.27 - $19.79 $16.11 - $18.49
ECS noted the Patterson-UTI's implied offer price of $20.20 per TMBR/Sharp Share was in excess of the equity reference value ranges implied by ECS' net asset value analysis. 29 SELECTED COMPARABLE ASSET TRANSACTIONS ANALYSIS ECS reviewed selected publicly available information related to 16 announced land-based drilling asset acquisitions announced between February 1999 and March 2003 located in North America (U.S. and Canada). The dataset for this analysis comprised selected transactions to acquire continental U.S. based land-drilling assets from February 1999 through March 2003. ECS reviewed the entire dataset for this analysis, taking into account all transactions listed and did not focus on any one particular transaction to derive the reference value range under this methodology. ECS reviewed purchase price multiples of drilling rigs for the acquired assets in each transaction. The number of transactions, the maximum, mean, median and minimum implied multiples as well as the selected benchmark ranges in these transactions were as follows: DRILLING ASSETS Number of Transactions...................................... 16 Purchase Price of Drilling Assets/Rigs ($MM/Rig) Maximum................................................... $6.1 Mean...................................................... $3.2 Median.................................................... $3.1 Minimum................................................... $1.0 Benchmark Multiples ($MM/Rig)............................... $3.0 - $3.5
After applying the benchmark multiples to TMBR/Sharp's corresponding rig count and adding estimates of TMBR/Sharp's yard inventory and other equipment as described above, ECS determined an enterprise reference value range for TMBR/Sharp's drilling assets. All transaction value to rig number datapoints for the selected transactions were available and were utilized in this analysis. ECS also reviewed selected publicly available information related to 67 announced oil and gas property acquisition transactions announced between January 2001 and May 2003 located primarily in the Texas Onshore and Mid Continent regions. Of a possible 134 transaction value datapoints to be considered, 108 were available and were utilized in this analysis. ECS reviewed purchase price multiples of equivalent reserves and equivalent daily production for the acquired assets in each transaction. For purposes of this analysis, an equivalency ratio of one barrel of oil to six thousand cubic feet of gas ("Mcfe") was used to compare quantities of oil with quantities of gas. The number of transactions, the maximum, mean, median and minimum implied multiples as well as the selected benchmark ranges in these transactions were as follows: OIL AND GAS ASSETS NUMBER OF TRANSACTIONS...................................... 67
PURCHASE PRICE OF DAILY PURCHASE PRICE OF RESERVES/ PRODUCTION/ PROVED RESERVES DAILY PRODUCTION ($/MCFE) ($/MCFE/DAY) --------------------------- ----------------------- Maximum.................................... $2.13 $8,915 Mean....................................... $1.06 $4,311 Median..................................... $0.99 $4,242 Minimum.................................... $0.44 $975 Benchmark Multiples ($/Mcfe & $/Mcfe/day).. $0.95 - $1.10 $4,000 - $4,400
ECS applied the benchmark multiples to TMBR/Sharp's corresponding proved reserve and current daily production figures to determine enterprise reference value ranges for TMBR/Sharp's oil and gas assets. The dataset for this analysis comprised selected transactions under $500 million to acquire exploration and production assets in the Texas onshore and Mid-Continent regions from January 2001 through May 2003. ECS reviewed the entire dataset for this analysis, taking into account all transactions 30 listed and did not focus on any one particular transaction to derive the reference value range under this methodology. Based on the enterprise reference value ranges determined above for the drilling and oil and gas business segments, respectively, and following adjustments for TMBR/Sharp's other corporate assets and liabilities, ECS determined a composite enterprise reference value range for TMBR/Sharp under this method of $90.3 million to $105.0 million. After adding net working capital of $9.4 million as of March 31, 2003, to the composite enterprise reference value range and dividing by the diluted number of shares of TMBR/Sharp Shares outstanding, the resulting equity reference value range per share of TMBR/Sharp Shares was $17.19 to $19.71. ECS noted the Patterson-UTI implied offer price of $20.20 per TMBR/Sharp Share was in excess of the equity reference value range implied by ECS' selected comparable asset transactions analysis. SELECTED COMPARABLE COMPANY TRANSACTIONS ANALYSIS Drilling Transactions ECS reviewed selected publicly available information on the following 15 company acquisition transactions and offers for control involving companies in the oil and gas drilling industry that were announced between April 1999 and February 2003:

The dataset for this analysis comprised selected transactions between oil and gas land drilling companies from April 1999 through February 2003. ECS reviewed the entire dataset for this analysis, taking into account all transactions listed and did not focus on any one particular transaction to derive the reference value range under this methodology. Using publicly available information, ECS reviewed the transaction value, which for the purposes of this analysis was defined as purchase price of equity plus net obligations assumed, multiples of last twelve months ("LTM") earnings before interest, taxes, depreciation, depletion and amortization and exploration expense ("EBITDX") and of drilling rigs for the target company in each transaction. The maximum, 31 mean, median and minimum implied multiples as well as the selected benchmark ranges in these transactions were as follows:
IMPLIED MULTIPLES IN RECENT TRANSACTIONS ----------------------------------------- MINIMUM MEDIAN MEAN MAXIMUM BENCHMARK RANGE --------- -------- ------ --------- --------------- Transaction Value/LTM EBITDX...... 4.0x 6.5x 8.7x 23.9x 6.0x - 8.5x Transaction Value/Rig ($MM/rig)... $1.3 $3.5 $4.0 $ 9.7 $3.5 - $4.5
ECS applied the benchmark multiples to TMBR/Sharp's LTM EBITDX (for the drilling business) and rig count to determine enterprise reference value ranges for TMBR/Sharp's drilling business. Of a possible 30 transaction datapoints to be considered, 22 were available and were utilized in this analysis. Oil and Gas Transactions ECS also reviewed selected publicly available information on the following 19 company acquisition transactions and offers for control involving companies in the oil and gas exploration and production industry that were announced between January 2002 and March 2003:

The dataset for this analysis comprised selected transactions between exploration and production companies with enterprise values of less than $1 billion from January 2003 through March 2003. ECS reviewed the entire dataset for this analysis, taking into account all transactions listed and did not focus on any one particular transaction to derive the reference value range under this methodology. Using publicly available information, ECS reviewed transaction value multiples of LTM EBITDX, equivalent proved reserves, and equivalent daily production for the target company in each transaction. The 32 maximum, mean, median and minimum implied multiples as well as the selected benchmark ranges in these transactions were as follows:
IMPLIED MULTIPLES IN RECENT TRANSACTIONS ------------------------------------------- MINIMUM MEDIAN MEAN MAXIMUM BENCHMARK RANGE --------- -------- -------- --------- --------------- Transaction Value/LTM EBITDX.... 2.9x 5.7x 7.0x 18.6x 5.5x - 7.0x Transaction Value/Daily Production($/Mcfe/d).......... $1,092 $3,873 $4,111 $7,923 $4,000 - $4,600 Transaction Value/Proved Reserves...................... $ 0.52 $ 1.02 $ 1.05 $ 1.43 $ 0.90 - $1.10
ECS applied the benchmark multiples to TMBR/Sharp's LTM EBITDX (for the oil and gas business), current equivalent daily production, and equivalent proved reserves to determine enterprise reference value ranges for TMBR/Sharp's oil and gas business. Of a possible 57 transaction datapoints to be considered, 50 were available and were utilized in this analysis. Premiums Paid ECS also performed a premium analysis, which compared the offer price per target company share with the target company's share price for the periods of one day, 30 days and 60 days prior to the public announcement of the offer. Transaction premiums for both drilling company and oil and gas company transactions were included. The maximum, mean, median, and minimum premiums, which for the purposes of this analysis was defined as the excess of the offer price over the target company's price stated as a percentage above the target company's share price, as well as the benchmark ranges selected by ECS for these periods were as follows:
IMPLIED PREMIUMS IN RECENT TRANSACTIONS ----------------------------------------- MAXIMUM MEAN MEDIAN MINIMUM BENCHMARK RANGE --------- ------ -------- --------- --------------- One Day Prior..................... 166% 40% 19% (10)% 20.0 - 40.0% 30 Days Prior..................... 110% 34% 22% (13)% 20.0 - 35.0% 60 Days Prior..................... 126% 41% 28% (12)% 25.0 - 40.0%
ECS applied these premium benchmarks to the corresponding stock prices of TMBR/Sharp for the periods of one day, 30 days and 60 days prior to May 23, 2003. All historical price datapoints for each selected transaction required in the premium analysis calculation were available and were utilized in this analysis. Based upon the enterprise reference value ranges implied by these multiples and the enterprise reference value ranges determined above for the drilling and oil and gas business segments, respectively, ECS determined a composite enterprise reference value range for TMBR/Sharp under this method of $95.0 million to $120.0 million. After adding net working capital of $9.4 million as of March 31, 2003, to the enterprise reference value range and dividing by the diluted number of shares of TMBR/Sharp common stock outstanding, the resulting equity reference value range per share of TMBR/Sharp common stock was $17.99 to $22.30. ECS noted the Patterson-UTI's implied offer price of $20.20 per TMBR/Sharp Share was within the equity reference value range implied by ECS' selected comparable company transactions analysis. SELECTED PUBLICLY TRADED COMPANIES ANALYSIS Using publicly available information, ECS calculated enterprise value multiples of historical and projected 2003 EBITDX and proved reserves for selected publicly traded companies with operating and financial characteristics comparable to TMBR/Sharp. Multiples of projected 2003 EBITDX for TMBR/Sharp were based upon 2003 EBITDX projections prepared by ECS and reviewed by TMBR/Sharp management. ECS obtained the enterprise value of each company by adding the sum of its long-term and short-term debt to the sum of the market value of its common equity as of May 23, 2003, the market value of its preferred stock (or, if not publicly traded, liquidation or book value) and the book value of its minority interest in other companies and subtracting cash. 33 ECS determined that the following drilling companies were relevant to an evaluation of TMBR/Sharp's drilling business based upon ECS' view of the comparability of the operating and financial characteristics of these companies to those of TMBR/Sharp: - Nabors Industries, Ltd. - Patterson-UTI - Helmerich & Payne, Inc. - Unit Corporation - Grey Wolf, Inc. - Parker Drilling Company - Pioneer Drilling Company The dataset for this analysis comprised selected publicly traded US-based land drilling companies. ECS reviewed the entire dataset for this analysis, taking into account all companies listed and did not focus on any one particular company to derive the reference value range under this methodology. The minimum, median, mean and maximum multiples for the seven drilling-oriented companies are set forth below. The table also includes benchmark multiple ranges selected by ECS based on a review of the selected comparable company multiples.
COMPARABLE COMPANY MULTIPLES ---------------------------------- MINIMUM MEDIAN MEAN MAXIMUM BENCHMARK RANGE ------- ------ ----- ------- --------------- Enterprise Value/LTM EBITDX.............. 6.8x 14.1x 17.5x 29.9x 11.0x - 14.0x Enterprise Value/2003 Estimated EBITDX... 5.6x 14.2x 13.1x 17.6x 9.0x - 13.0x
ECS applied the benchmark multiples to TMBR/Sharp's LTM EBITDX and 2003 estimated EBITDX (for the drilling business) to determine enterprise reference value ranges for TMBR/Sharp's drilling business. ECS also determined that the following companies were relevant to an evaluation of the oil and gas business of TMBR/Sharp based upon ECS' view of the comparability of the operating and financial characteristics of these companies to those of TMBR/Sharp: - Beta Oil & Gas, Inc. - Brigham Exploration Co. - Carrizo Oil & Gas, Inc. - Clayton Williams Energy, Inc. - Contango Oil & Gas Co. - Edge Petroleum Corp. - PetroCorp, Inc. - The Exploration Company - Wiser Oil Company The dataset for this analysis comprised selected publicly traded exploration and production companies with an enterprise value of less than $250 million and operations primarily focused in the Texas onshore and Mid-Continent regions. ECS reviewed the entire dataset for this analysis, taking into account all companies listed and did not focus on any one particular company to derive the reference value range under this methodology. 34 The minimum, median, mean and maximum multiples for the nine companies are set forth below. The table also includes benchmark multiple ranges selected by ECS based on a review of the selected comparable company multiples.
COMPARABLE COMPANY MULTIPLES ---------------------------------- MINIMUM MEDIAN MEAN MAXIMUM BENCHMARK RANGE ------- ------ ----- ------- --------------- Enterprise Value/LTM EBITDX.............. 2.5x 5.2x 5.8x 10.1x 4.0x - 6.0x Enterprise Value/2003 Estimated EBITDX... 2.8x 3.6x 3.7x 5.1x 3.0x - 4.0x Enterprise Value/Proved Reserves ($/Mcfe)............................... $1.06 $1.77 $1.92 $3.58 $1.50 - $1.90
ECS applied the benchmark multiples to TMBR/Sharp's LTM EBITDX, 2003 estimated EBITDX (for the oil and gas business) and proved reserve estimates to determine enterprise reference value ranges for TMBR/Sharp's oil and gas business. Based upon the enterprise reference value ranges determined above for the drilling and oil and gas business segments, respectively, ECS determined a composite enterprise reference value range for TMBR/Sharp under this method of $90.0 million to $120.0 million. After adding net working capital of $9.4 million as of March 31, 2003, to the composite enterprise reference value range and dividing by the diluted number of TMBR/Sharp Shares outstanding, the composite equity reference value range per TMBR/Sharp Share was $17.13 to $22.30. ECS noted the Patterson-UTI's implied offer price of $20.20 per TMBR/Sharp Share was within the equity reference value range implied by ECS' selected publicly traded companies analysis. GOING CONCERN ANALYSIS ECS projected the potential financial performance of TMBR/Sharp, without giving effect to the merger, for the five-year period beginning on January 1, 2003, utilizing two cases and various assumptions for both the drilling and oil and gas business segments. Going Concern Case 1 used a constant exit multiple of 6.0x projected 2007 EBITDX, a sensitivity of annual dayrate/utilization rate increases of 1%, 3%, and 5% for the drilling business with associated increases in corporate overhead and drilling maintenance capital expenditures, and the three different pricing assumptions and operating projections assumptions as described above in the "Net Asset Value Analysis" for the oil and gas business. Going Concern Case 2 used the same variables as in Going Concern Case 1 for the drilling business, the 5-Year Historical Price Case for the oil and gas business with the same operating projections assumptions as in the "Net Asset Value Analysis," and exit multiples of 5.0x, 6.0x, and 7.0x projected 2007 EBITDX. ECS prepared these projections using operating and reserve projections prepared and/or provided by TMBR/Sharp management and staff (or their consultants) and certain assumptions based upon discussions with TMBR/Sharp management regarding TMBR/Sharp's potential future operating and financial performance. From the equity reference values implied by this analysis, ECS determined a composite equity reference value range per diluted TMBR/Sharp Share of $18.00 to $23.00. ECS noted the Patterson-UTI's implied offer price of $20.20 per TMBR/Sharp Share was within the composite equity reference value range implied by the going concern analysis. PRO FORMA MERGER ANALYSIS ECS analyzed the pro forma financial effects of the merger as of May 23, 2003, and for the fiscal years ended 2003 and 2004 with operating projections based upon research analyst estimates for Patterson-UTI and projections prepared by ECS for TMBR/Sharp (with review by TMBR/Sharp management). For purposes of its analysis, ECS used the merger exchange ratio and assumed the merger would be accounted for using purchase accounting. ECS also assumed that the merger consideration would be 45% cash and 55% stock, TMBR/Sharp's selling, general and administrative expenses would decrease by 50% as a result of merger synergies, and the corporate income tax rate would be 35%. The pro forma merger analysis indicated that the merger would be accretive to Patterson-UTI's 2003 and 2004 estimated earnings 35 by 3.0% and 2.8%, respectively, and accretive to Patterson-UTI's 2003 and 2004 cash flow by 12.1% and 8.7%, respectively. GENERAL The description set forth above constitutes a summary of the analyses employed and factors considered by ECS in rendering its opinion to the TMBR/Sharp board of directors. ECS believes that its analyses must be considered as a whole and that selecting portions of its analyses, without considering all analyses and factors, could create an incomplete view of the process underlying its opinion. The preparation of a fairness opinion is a complex analytical process involving various determinations as to the most appropriate and relevant methods of financial analysis and the application of those methods to the particular circumstances and is not necessarily susceptible to partial analysis or summary description. In arriving at its opinion, ECS did not attribute any particular weight to any analysis that it considered, but rather made qualitative judgments as to the significance and relevance of each analysis. Any estimates resulting from the analyses are not necessarily indicative of actual values, which may be significantly more or less favorable than as set forth in this document. In addition, analyses based on forecasts of future results are not necessarily indicative of future results, which may be significantly more or less favorable than suggested by these analyses. Estimates of reference values of companies do not purport to be appraisals or necessarily reflect the prices at which companies may actually be sold. Because the estimates are inherently subject to uncertainty and based upon numerous factors or events beyond the control of the parties and ECS, ECS cannot assure you that the estimates will prove to be accurate. No transaction involving companies other than Patterson-UTI and TMBR/Sharp used in the analyses of selected comparable transactions is identical to TMBR/Sharp, Patterson-UTI or the proposed merger. Accordingly, these analyses must take into account differences in the financial and operating characteristics of the selected publicly traded companies and differences in the structure and timing of the selected transactions and other factors that would affect the public trading values and acquisition values of the companies considered. ECS, as part of its investment banking business, is continually engaged in the evaluation of energy-related businesses and their securities in connection with mergers and acquisitions, private placements and valuations for corporate and other purposes. TMBR/Sharp selected ECS as its financial advisor because it is an investment banking firm whose principals have substantial experience in transactions similar to the proposed merger. Pursuant to an engagement letter between ECS and TMBR/Sharp dated as of November 13, 2002 (and as amended March 3, 2003), TMBR/Sharp agreed to pay to ECS (i) a retainer fee of $50,000 in cash, payable promptly following TMBR/Sharp's execution of the engagement letter, (ii) an opinion fee of $450,000 in cash, payable promptly upon delivery of a written fairness opinion by ECS, regardless of the conclusion reached by ECS in the opinion and (iii) a transaction fee of 0.5% of the transaction proceeds in cash conditioned upon consummation of the merger. The 0.5% transaction fee to be received by ECS on completion of the merger is based on the closing price of Patterson-UTI Shares on the day of the closing of the merger and excludes TMBR/Sharp Shares owned by Patterson-UTI and TMBR/Sharp before the merger. Assuming the closing price of Patterson-UTI Shares on the day of the merger is the same as at the end of the trading day on , 2003, $[ ], the transaction consideration would be $[ ] in cash and [ ] in Patterson-UTI Shares, resulting in total transaction consideration of $[ ] and a transaction fee payable to ECS of $[ ]. In addition, TMBR/Sharp also agreed to reimburse ECS for its reasonable out-of-pocket expenses related to its rendering of financial advisory services to TMBR/Sharp, including the reasonable fees and expenses of its counsel. TMBR/Sharp also agreed to indemnify ECS and its affiliates, the respective directors, officers, partners, agents, employees of ECS and its affiliates and controlling persons for certain expenses, losses, claims, damages and liabilities related to or arising out of its rendering of services under its engagement as financial advisor. During the 36 past two years, TMBR/Sharp has not paid any fees to ECS, Mr. Weinberg or any of their affiliates except in connection with the retention of ECS as financial advisor to TMBR/Sharp in the merger. SOURCE OF FUNDS FOR CASH PORTION OF MERGER CONSIDERATION Patterson-UTI currently intends to pay the cash portion of the merger consideration to TMBR/Sharp shareholders out of funds available on hand and existing financing facilities. INTERESTS OF CERTAIN PERSONS IN THE MERGER GENERAL In considering the recommendation of the TMBR/Sharp board of directors, you should be aware that certain members of TMBR/Sharp's management team and board of directors, including Mr. Brown, have interests in the merger that are different from, or in addition to, your interests as a TMBR/Sharp shareholder. These interests include compensatory payments to be paid pursuant to retention agreements with eight officers and directors of TMBR/Sharp, and the receipt of cash payments in exchange for the cancellation and termination of stock options held by these same officers and directors to purchase TMBR/Sharp Shares. In the aggregate, the payments to the eight officers and directors under the retention agreements and the cash-out of stock options held by these officers and directors will be approximately $6,116,466, including a payment of $700,800 to Mr. Brown pursuant to his retention agreement and approximately $3,482,625 in connection with the cash-out of his stock options. For the reasons described below, these additional interests did not affect the TMBR/Sharp board's ability to exercise its judgment solely for the benefit of TMBR/Sharp and its shareholders: - TMBR/Sharp's board was aware of these additional interests and the board's decision to approve the merger was made with full knowledge of the existence of these additional interests and their terms; - the officers' retention agreements were recommended by non-employee directors solely for the purpose of ensuring that TMBR/Sharp's officers would continue to devote their services for the best interests of TMBR/Sharp and its shareholders and not be distracted by the uncertainties created by Patterson-UTI's ownership interest in TMBR/Sharp and any potential change in control; - the TMBR/Sharp directors believed the officers' retention agreements to be prudent and in the best interests of TMBR/Sharp and its shareholders; - these additional interests were not implemented for the purpose of creating a deterrent to any takeover proposal; - all of the stock options held by the officers and directors of TMBR/Sharp were granted in the normal course of business in accordance with TMBR/Sharp's past practices and not in contemplation of the proposed transaction with Patterson-UTI or any other party; and - four of the five TMBR/Sharp directors are non-employee directors, and the only compensation that each such non-employee director will receive in connection with the merger is $30,200 resulting from the cash-out of such director's stock options. RETENTION AGREEMENTS In November 2002, TMBR/Sharp entered into retention agreements with Thomas C. Brown, TMBR/Sharp's Chairman of the Board and Chief Executive Officer, Jeffrey D. Phillips, TMBR/Sharp's President, Don H. Lawson, TMBR/Sharp's Vice-President of Operations, Patricia R. Elledge, TMBR/Sharp's Treasurer and Controller and six other TMBR/Sharp employees. TMBR/Sharp entered into these retention agreements as a result of the determination of the TMBR/Sharp board of directors and compensation committee that it was imperative for TMBR/Sharp to be able to rely upon these individuals to continue in their respective positions with TMBR/Sharp without concern that such employees might be distracted by the personal uncertainties and risks created by any proposed change of control of TMBR/ 37 Sharp. Each retention agreement provides for the payment of a cash bonus within five days following the consummation of the merger in an amount that is equal to the officer's base salary during the preceding twelve months times an applicable multiple. The table below sets forth the applicable multiple for each officer who has a retention agreement:
NAME APPLICABLE MULTIPLE BASE SALARY(1) RETENTION PAYMENT(2) ---- ------------------- -------------- -------------------- Thomas C. Brown..................... 2.92x $240,000 $700,800 Jeffrey D.

The amount for Mr. Phillips reflects such a reduction. CONSIDERATION FOR TMBR/SHARP SHARES The directors and officers of TMBR/Sharp will receive the same per share consideration for their TMBR/Sharp Shares in the merger as every other TMBR/Sharp shareholder. The table below sets forth the estimated aggregate amount of consideration that will be received in the merger by TMBR/Sharp directors and officers on account of their ownership of TMBR/Sharp Shares as of November 1, 2003:

STOCK OPTIONS If the TMBR/Sharp shareholders approve the merger agreement, after the special meeting but before the completion of the merger, TMBR/Sharp will make a cash payment to each holder of a stock option granted under a TMBR/Sharp benefit plan. The cash amount to be paid for each TMBR/Sharp Share subject to the option will equal the difference between $20.20 and the exercise price per TMBR/Sharp Share subject to the option, less applicable withholding taxes. All stock options to purchase TMBR/Sharp Shares will vest after the merger is approved at the special meeting and before the completion of the merger. The following table sets forth the number of TMBR/Sharp Shares subject to stock options that are owned by the officers and directors of TMBR/Sharp as of November 1, 2003, and the amount that each 38 officer and director will receive in exchange for the cancellation and termination of those options in connection with the merger:

EMPLOYMENT AGREEMENTS Other than the retention agreements and option agreements entered into by TMBR/Sharp with its directors and officers, as disclosed in "-- Retention Agreements" and "-- Stock Options", none of TMBR/Sharp's directors or officers is a party to an employment agreement that would require any payment upon completion of the merger. INDEMNIFICATION OF DIRECTORS AND OFFICERS; DIRECTORS' AND OFFICERS' INSURANCE The merger agreement provides that Patterson-UTI will indemnify each of our present and former directors and officers after the effective time of the merger. The merger agreement further provides that for a period of six years after the effective time of the merger, Patterson-UTI must use commercially reasonable efforts to purchase and maintain in effect for TMBR/Sharp's directors and officers liability insurance protection with the same coverage and in the same amount and on terms and conditions no less favorable to such individuals than that provided by our current insurance policies; provided that Patterson- UTI will not be required to pay an annual premium for such insurance in excess of two times the last annual premium paid by TMBR/Sharp prior to the merger agreement. In such case Patterson-UTI will purchase as much coverage as possible for such amount. The persons benefiting from the insurance provisions of the merger agreement include all persons who serve or have served as officers or directors of TMBR/Sharp, or an officer, director or employee of TMBR/Sharp who acts as a fiduciary under any TMBR/Sharp employee benefit plan. DIRECTORS AND OFFICERS None of the directors or officers of TMBR/Sharp will become a director or officer of Patterson-UTI in connection with the merger. Patterson-UTI currently has no arrangements or agreements with any of the officers of TMBR/Sharp regarding employment following completion of the merger. Patterson-UTI and Messrs. Brown, Phillips and Lawson, however, may consider employment or consulting arrangements in the future. TRANSACTIONS WITH PATTERSON-UTI Since July 2001, Tri-C Resources, Inc., a privately owned oil and gas exploration company controlled by Michael M. Cone, has utilized the contract drilling services of Patterson-UTI for the purposes of drilling eight wells owned and operated by Tri-C in Matagorda and Jackson Counties, Texas. Tri-C paid a total of approximately $1,020,882 to Patterson-UTI for these contract drilling services. Tri-C selected Patterson-UTI as its drilling contractor after obtaining competitive bids from three contract drilling companies, including Patterson-UTI. Mr. Cone has been a director of TMBR/Sharp since March 2001. 39 BHC Pipe and Equipment Company, a privately held oil field equipment supply company controlled by Raymond H. Batchelor, has sold drilling equipment from time to time to Patterson-UTI and certain of its predecessors. Since February 2000, BHC has invoiced Patterson-UTI and its predecessors for a total of approximately $120,605 for equipment sales. Mr. Batchelor has been a director of TMBR/Sharp since March 2001. EMPLOYEE COMPENSATION AND BENEFITS From and after the effective time of the merger, individuals who are officers of TMBR/Sharp who continue as employees of Patterson-UTI or Sub will be immediately eligible to participate in any qualified employee benefit plan maintained and sponsored by Patterson-UTI and will be credited with vesting service for their years of service with TMBR/Sharp. In addition, Patterson-UTI will generally provide compensation and employee benefits, which are comparable to the compensation and employee benefits provided to all similarly situated employees of Patterson-UTI, to each TMBR/Sharp officer who continues as an employee of Patterson-UTI after the merger. ACCOUNTING TREATMENT The merger will be accounted for as a business combination using the "purchase" method of accounting under generally accepted accounting principles in the United States. Patterson-UTI will be the acquiror for financial accounting purposes. OPINIONS THAT THE MERGER CONSTITUTES A REORGANIZATION UNDER SECTION 368(a) OF THE INTERNAL REVENUE CODE The completion of the merger is conditioned on, among other things, the receipt of opinions from tax counsel for each of Patterson-UTI and TMBR/Sharp that the merger will qualify as a "reorganization" under Section 368(a) of the Internal Revenue Code. These opinions will be delivered only if the holders of TMBR/Sharp Shares receive in the merger an amount of Patterson-UTI Shares with a value equal to at least forty percent (40%) of the total consideration paid by Patterson-UTI for all TMBR/Sharp Shares. The total consideration takes into account the amount of cash paid or deemed to be paid to holders of TMBR/Sharp Shares in connection with the merger, cash paid to holders of TMBR/Sharp Shares who perfect their dissenters' rights and cash paid by Patterson-UTI to acquire TMBR/Sharp Shares within twelve (12) months of the date of the merger agreement. In addition to the market value of the Patterson-UTI Shares on the date of the merger and the other items described above, various factors affect the determination of whether the value of the Patterson-UTI Shares received by the TMBR/Sharp shareholders in exchange for TMBR/Sharp Shares is equal to at least forty percent (40%) of the combined value of the total consideration paid by Patterson-UTI for all TMBR/Sharp Shares, including: - The amount, if any, to be paid to TMBR/Sharp shareholders who perfect their dissenters' rights; - Whether prior to and in connection with the merger TMBR/Sharp (or certain parties related to TMBR/Sharp) redeems or acquires TMBR/Sharp Shares or makes distributions to the TMBR/Sharp shareholders; and - Whether there will be any repurchases by Patterson-UTI (or certain parties related to Patterson-UTI) of the Patterson-UTI Shares to be issued in the merger. Accordingly, it may not be possible to state with certainty the minimum trading price of the Patterson-UTI Shares that would cause the value of the Patterson-UTI Shares to be received in the merger to be equal to at least forty percent (40%) of the combined value of the total consideration paid by Patterson-UTI for all TMBR/Sharp Shares. If, on or before the closing date, it is determined that Patterson-UTI and TMBR/Sharp will not receive opinions from their respective tax counsels to the effect that the merger will qualify as a 40 "reorganization" under Section 368(a) of the Code and the parties agree to proceed with a taxable transaction under a revised structure, an amended proxy statement/prospectus with revised disclosure regarding the new structure and material United States federal tax consequences will be mailed to you at least 20 days prior to the special meeting. If the shareholders have already voted to approve the merger, TMBR/Sharp would hold another special meeting to vote on the revised merger proposal after the amended proxy statement/prospectus had been mailed to you. REGULATORY MATTERS Under the HSR Act, the parties cannot complete the merger until they have notified and furnished information to the Federal Trade Commission and the Antitrust Division of the United States Department of Justice and a specified waiting period expires or is terminated. Patterson-UTI and TMBR/Sharp filed the required notification and report forms under the HSR Act with the FTC and the Antitrust Division on June 11, 2003. On July 3, 2003, the FTC notified the parties that the FTC and the Antitrust Division had terminated the specified waiting period under the HSR Act. Each state in which Patterson-UTI or TMBR/Sharp has operations also may review the merger under state antitrust laws. At any time before the effective time of the merger, the FTC, the Antitrust Division, a state or non-U.S. governmental authority or a private person or an entity could seek under the antitrust laws, among other things, to enjoin the merger or to cause Patterson-UTI or TMBR/Sharp to divest assets or businesses as a condition to completion of the merger. If a challenge to the merger is made, Patterson-UTI and TMBR/Sharp may not prevail. The obligations of Patterson-UTI and TMBR/Sharp to consummate the merger are subject to the condition that there be no order or injunction of a U.S. or non-U.S. court of competent jurisdiction or other governmental authority that prohibits the consummation of the merger. Each party has agreed to use its reasonable efforts to have any such order or injunction lifted or vacated. Patterson-UTI and TMBR/Sharp believe that they will obtain all material required regulatory approvals prior to the special meeting. It is not certain, however, that all approvals will be received by that time, or at all, and governmental authorities may impose unfavorable conditions for granting the required approvals. INTERESTED SHAREHOLDER TRANSACTIONS UNDER TEXAS LAW TMBR/Sharp is a Texas corporation. In general, Article 13 of the TBCA prevents an "interested shareholder," which is generally a person who owns or has the right to acquire 20% or more of a corporation's outstanding voting stock, or an affiliate or associate thereof, from engaging in a "business combination," which is defined to include mergers and certain other transactions, with a Texas corporation for a period of three years following the date such person became an interested shareholder unless, among other things, prior to such date the board of directors of the corporation approved either the business combination or the transaction in which the interested shareholder became an interested shareholder. The board of directors of TMBR/Sharp has recommended the merger, approved the merger agreement and the other transactions contemplated by the merger agreement and has rendered inapplicable to the merger the provisions of Article 13 of the TBCA. FEDERAL SECURITIES LAWS CONSEQUENCES; RESALE RESTRICTIONS All Patterson-UTI Shares that will be distributed to TMBR/Sharp shareholders in the merger will be freely transferable, except for restrictions applicable to "affiliates" of TMBR/Sharp. Persons who are deemed to be affiliates of TMBR/Sharp may resell Patterson-UTI Shares received by them only in transactions permitted by the resale provisions of Rule 145 or as otherwise permitted under the Securities Act. Persons who may be deemed to be affiliates of TMBR/Sharp generally include executive officers, directors and significant shareholders of TMBR/Sharp. The merger agreement requires TMBR/Sharp to cause each of its directors and executive officers who TMBR/Sharp believes may be deemed to be 41 affiliates of TMBR/Sharp to execute a written agreement to the effect that those persons will not sell, assign or transfer any of the Patterson-UTI Shares issued to them in the merger unless that sale, assignment or transfer has been registered under the Securities Act, is in conformity with Rule 145 or is otherwise exempt from the registration requirements under the Securities Act. This proxy statement/prospectus does not cover any resales of the Patterson-UTI Shares to be received by TMBR/Sharp's shareholders in the merger, and no person is authorized to make any use of this proxy statement/prospectus in connection with any resale. DISSENTERS' RIGHTS OF APPRAISAL Each holder of TMBR/Sharp Shares has the right to dissent to the merger in accordance with Articles 5.11 through 5.13 of the TBCA ("Articles 5.11-5.13"). If the statutory procedures are complied with and the merger is consummated, dissenting holders would be entitled to receive cash equal to the "fair value" of the shares held by them in lieu of receiving consideration proposed under the merger agreement. See Annex C to this proxy statement/prospectus. Such "fair value" is determined as of the day immediately preceding the special meeting (excluding any appreciation or depreciation in anticipation of the merger). In addition, dissenting shareholders may be entitled to receive payment of interest beginning 91 days from the date of consummation of the merger to the date of a judicial determination on the amount determined to be the fair value of their shares. Any judicial determination of the fair value of the shares could be based upon considerations other than or in addition to the merger consideration and the market value of the shares, including asset values, the investment value of the shares and any other valuation considerations generally accepted in the investment community. The value so determined for dissenting shares could be more than, less than or equal to the merger consideration, and payment of such consideration would take place subsequent to payment pursuant to the merger. The TBCA provides that, in the absence of fraud in the transaction, the statutory dissenters' rights remedy provided under the TBCA to a shareholder objecting to the merger is the exclusive remedy for the recovery of the value of such shareholder's shares or for money damages to such shareholder with respect to the merger. If TMBR/Sharp complies with the requirements of Article 5.12 of the TBCA, any shareholder who fails to comply with the requirements of that Article will not be entitled to bring suit for the recovery of the value of his shares or for money damages to the shareholder with respect to the merger. The rights of dissenting holders of TMBR/Sharp shares are governed by Articles 5.11-5.13. The following summary of applicable provisions of Articles 5.11-5.13 is not intended to be a complete statement of such provisions and is qualified in its entirety by reference to the full text of Articles 5.11-5.13, which is attached to this proxy statement/prospectus as Annex C and incorporated by reference herein. A holder of TMBR/Sharp Shares who has filed a written objection to the merger prior to the special meeting, who has not voted in favor of approval of the merger agreement and who has made a demand for compensation, all as provided under Articles 5.11-5.13 is entitled under such provisions, as an alternative to receiving the consideration offered in the merger for his shares, to the fair value of his shares. The following is a summary of the procedural steps that must be taken if the dissenters' rights are to be validly exercised. TMBR/Sharp shareholders may elect to exercise their right to dissent from the merger by filing with TMBR/Sharp, at the address set forth below, prior to the special meeting, a written objection to the merger, setting forth that such shareholder's right to dissent will be exercised if the merger is effected and such shareholder's address for any notice. If the merger is effected and such shareholder has not voted in favor of approving the merger agreement, TMBR/Sharp will within ten (10) days after the merger is effected, deliver or mail to such shareholder written notice that the merger has been effected, and such shareholder may, within ten 42 (10) days from the delivery or mailing of such notice, make written demand on TMBR/Sharp for payment of the fair value of such holder's shares. The fair value of any dissenting shares will be the value thereof as of the day immediately preceding the special meeting, excluding any appreciation or depreciation in anticipation of the merger. The shareholder demand will state the number of shares owned by the dissenting shareholder and the fair value of such shares as estimated by him. Any shareholder failing to make demand within the ten (10) day period will be bound by the merger. A dissenting shareholder's written objection to the merger and demand for payment must be in addition to and separate from any vote against approval of the merger agreement. Neither voting against, abstaining from voting, nor failing to vote for approval of the merger agreement will constitute the written notice required to be filed by a dissenting shareholder. Failure to vote against the approval of the merger agreement, however, will not constitute a waiver of rights under Articles 5.11-5.13, provided that a written notice has been properly delivered. A shareholder voting for the approval of the merger agreement will be deemed to have waived his dissenters' rights. Under Articles 5.11-5.13, holders of record of shares are entitled to dissenters' rights as described above, and the procedures to perfect such rights must be carried out by and in the name of holders of record. Persons who are beneficial but not record owners of shares and who wish to exercise dissenters' rights with respect to the merger should consult promptly with the record holders of their shares as to the exercise of such rights. All written objections and demands for payment should be addressed to TMBR/Sharp Drilling, Inc., 4607 West Industrial Boulevard, Midland, Texas 79703, Attn: James M. Alsup, Secretary. All written objections and demand for payment must be received before the special meeting. Demands for payment must be made as described above. Within twenty (20) days after receipt by TMBR/Sharp of a demand for payment made by a dissenting shareholder, TMBR/Sharp must deliver or mail to such dissenting shareholder a written notice that will either (i) state that TMBR/Sharp accepts the amount claimed in the demand and agrees to pay that amount within ninety (90) days after the date on which the merger was effected upon the surrender of the stock certificates duly endorsed or (ii) will contain an estimate by TMBR/Sharp of the fair value of such shares, together with an offer to pay the amount of that estimate within ninety (90) days after the date on which the merger was effected, upon receipt of notice within sixty (60) days after that date from the dissenting shareholder that such shareholder agrees to accept that amount, upon the surrender of the stock certificates duly endorsed. In addition, within the twenty (20) day period after demanding payment for his shares, each holder of certificates representing shares so demanding payment shall submit such certificates to TMBR/Sharp for notation thereon that such demand has been made. The failure of holders of certificates representing shares to do so will, at TMBR/Sharp's option, terminate such shareholder's rights under the provisions of the TBCA relating to dissenters' rights unless a court of competent jurisdiction for good and sufficient cause shown shall otherwise direct. If, within sixty (60) days after the date on which the merger was effected, the value of such shares is agreed upon between the dissenting shareholder and the surviving company, payment therefor will be made within ninety (90) days after the date on which the merger was effected and upon surrender of the stock certificates duly endorsed. Upon payment of the agreed value, the dissenting shareholder will cease to have any interest in the shares or in TMBR/Sharp. If, within sixty (60) days after the date on which the merger was effected, the dissenting shareholder and the surviving company do not so agree, then the dissenting shareholder or the surviving company may, within sixty (60) days after the expiration of the sixty (60) day period, file a petition in any court of competent jurisdiction in the county in which TMBR/Sharp's principal office is located, asking for a finding and determination of the fair value of such dissenting shareholder's shares. In connection with the filing of a petition, TMBR/Sharp will provide such court with a list of names and addresses of all its shareholders who have demanded payment for their shares and with whom agreements as to the value of their shares have not been reached. After the hearing of the petition, the 43 court will determine the dissenting shareholders who have complied with the provisions of the TBCA relating to dissenters' rights and have become entitled to the value of and payment for their shares, and will appoint one or more qualified appraisers to determine the value. The appraisers will determine the fair value of the shares held by the dissenting shareholders adjudged by the court to be entitled to payment and will file their report of the value in the office of the clerk of the court. The court will determine the fair value of the shares held by the dissenting shareholders entitled to payment therefor and will direct the payment of that value by the Sub, as the surviving company in the merger, together with interest thereon, beginning 91 days after the date on which the merger was effected to the date of such judgment, to the dissenting shareholders entitled thereto. Upon payment of the judgment by TMBR/Sharp to such dissenting shareholders, the dissenting shareholders will cease to have any interest in those shares or in TMBR/Sharp. In the absence of fraud in the transaction, the remedy provided by the provisions of the TBCA relating to dissenters' rights to a shareholder objecting to the merger is the exclusive remedy for the recovery of the value of his shares or money damages to such shareholder with respect to the merger. If TMBR/Sharp complies with the requirements of Article 5.12, in the absence of fraud in the transaction, any dissenting shareholder who fails to comply with the requirements of the provisions of such Article will not be entitled to bring suit for the recovery of the value of his shares or money damages to such shareholder with respect to the merger. Any shareholder who has demanded payment for his shares and has not voted in favor of the merger agreement as described above shall not thereafter be entitled to vote or exercise any other rights of a shareholder except (i) the right to receive payment for his shares pursuant to the provisions described above and (ii) the right to maintain an appropriate action to obtain relief on the ground that the merger would be or was fraudulent. Such shares shall not thereafter be considered outstanding for the purposes of any subsequent vote of TMBR/Sharp shareholders. Any shareholder who has demanded payment for his shares as described above may withdraw such demand at any time before payment for his shares or before any petition has been filed asking for a finding and determination of the fair value of such shares, but no such demand may be withdrawn after such payment has been made or, unless TMBR/Sharp shall consent thereto, after any such petition has been filed. If, however, such demand is withdrawn as herein before provided, or if TMBR/Sharp terminates the shareholder's rights as provided above, or if no petition asking for a finding and determination of fair value of such shares by a court has been filed within the time period described above, or if after the hearing of a petition filed as described above, the court determines that such shareholder is not entitled to the relief as described above, then, in any such case, such shareholder and all persons claiming under him will be conclusively presumed to have approved and ratified the merger from which he dissented and will be bound thereby, the right of such shareholder to be paid the fair value of his shares will cease, and his status as a shareholder will be restored without prejudice to any corporate proceedings which may have been taken during the interim, and such shareholder will be entitled to receive any dividends or other distributions made to holders of shares in the interim. Any shareholder contemplating the exercise of dissenters' rights is urged to read carefully the provisions of the TBCA relating to dissenters' rights, attached hereto as Annex C. FAILURE TO COMPLY STRICTLY WITH ALL OF THE PROCEDURES SET FORTH IN ARTICLES 5.11-5.13 OF THE TBCA MAY RESULT IN THE LOSS OF A SHAREHOLDER'S STATUTORY APPRAISAL RIGHTS. CONSEQUENTLY, ANY SHAREHOLDER WISHING TO EXERCISE APPRAISAL RIGHTS IS URGED TO CONSULT LEGAL COUNSEL BEFORE ATTEMPTING TO EXERCISE APPRAISAL RIGHTS. 44 THE MERGER AGREEMENT The following is a summary of the merger agreement, which is attached as Annex A to this proxy statement/prospectus and incorporated in this document. To understand the merger more fully, and for a more complete legal description of the merger, you are urged to read carefully the entire proxy statement/prospectus, including the merger agreement and the other annexes. STRUCTURE OF THE MERGER Upon the terms and conditions of the merger agreement, and in accordance with Texas law, at the effective time of the merger, TMBR/Sharp will merge with and into Sub. Sub will be the surviving company under the name TMBR/Sharp Drilling, LLC, and will be a wholly owned subsidiary of Patterson-UTI. The separate corporate existence of TMBR/Sharp will cease at the effective time of the merger. WHEN THE MERGER BECOMES EFFECTIVE The closing date of the merger will occur on the second business day following the date on which all conditions to the merger, other than those conditions that by their nature are to be satisfied at the closing, have been satisfied or waived, unless the parties agree on another time. Contemporaneously with the closing, Sub and TMBR/Sharp will file articles of merger with the Secretary of State of the State of Texas. The effective time of the merger will be the time Sub and TMBR/Sharp file the articles of merger with the Secretary of State of the State of Texas or at a later time as we may agree and specify in the articles of merger. CONVERSION OF STOCK AND STOCK OPTIONS At the effective time of the merger: - each outstanding share of TMBR/Sharp common stock, except those (1) shares owned directly or indirectly by Patterson-UTI or TMBR/Sharp, including treasury stock, and (2) shares held by TMBR/Sharp shareholders who validly exercise their dissenters' rights under Texas law, will be converted into the right to receive $9.09 in cash and 0.312166 of a Patterson-UTI Share; - TMBR/Sharp Shares held by TMBR/Sharp shareholders who exercise their dissenters' rights under Texas law will be treated as described under "The Merger -- Dissenters' Rights of Appraisal", assuming that those shareholders validly exercise their dissenters' rights; and - TMBR/Sharp Shares owned or held by Patterson-UTI or TMBR/Sharp, including treasury stock, will be canceled. If, before the effective time of the merger, the issued and outstanding Patterson-UTI Shares or TMBR/Sharp Shares are changed into a different number of shares as a result of a reclassification, recapitalization, stock split, stock combination, stock dividend or share exchange, an appropriate and proportionate adjustment will be made to the number of Patterson-UTI Shares to be received by the TMBR/Sharp shareholders. If the TMBR/Sharp shareholders approve the merger agreement, after the special meeting but before the completion of the merger, TMBR/Sharp will make a cash payment to each holder of a stock option granted under a TMBR/Sharp benefit plan. The cash amount to be paid for each TMBR/Sharp Share subject to the option will equal the difference between $20.20 and the exercise price per TMBR/Sharp Share subject to the option, less applicable withholding taxes. All stock options to purchase TMBR/Sharp Shares will vest after the merger is approved at the special meeting and before the completion of the merger. For a description of Patterson-UTI Shares and TMBR/Sharp Shares and a description of the comparative rights of holders of Patterson-UTI Shares and TMBR/Sharp Shares, see "Comparison of the Rights of Patterson-UTI Stockholders and TMBR/Sharp Shareholders". 45 EXCHANGE PROCEDURES EXCHANGE AGENT As soon as practicable after the effective time of the merger, Sub will deposit with the exchange agent, for the benefit of the holders of TMBR/Sharp Shares, an amount in cash and certificates representing Patterson-UTI Shares sufficient to effect the conversion of TMBR/Sharp Shares into the cash and stock consideration to be paid in the merger. Sub will also make funds available to the exchange agent from time to time after the effective time of the merger as needed to pay any cash instead of fractional shares or any dividends or other distributions declared by Patterson-UTI on Patterson-UTI Shares with a record date after the effective time of the merger and a payment date on or before the date the relevant TMBR/Sharp stock certificate was surrendered. At the effective time of the merger, the stock transfer books of TMBR/Sharp will be closed and no further issuances or transfers of TMBR/Sharp Shares will be made. If, after the effective time, valid TMBR/Sharp stock certificates are presented to the surviving company for any reason, they will be cancelled and exchanged as described above to the extent allowed by applicable law. EXCHANGE OF SHARES Promptly after the effective time of the merger, the exchange agent will mail to you a transmittal letter and instructions explaining how to surrender your certificates to the exchange agent. TMBR/Sharp shareholders who surrender their stock certificates to the exchange agent, together with a properly completed and signed transmittal letter and any other documents required by the instructions to the transmittal letter, will receive: - Patterson-UTI Shares certificates representing the number of whole shares to which each holder is entitled in accordance with the 0.312166 exchange ratio; and - A check, after any required tax withholdings are deducted, in the aggregate amount of: - $9.09 per TMBR/Sharp Share surrendered to the exchange agent; - the amount of cash being paid in lieu of fractional Patterson-UTI Shares; and - any cash dividends and any other dividends or other distributions declared by Patterson-UTI on Patterson-UTI Shares with a record date after the effective time of the merger and a payment date on or before the date the relevant TMBR/Sharp stock certificate was surrendered. If you have a TMBR/Sharp stock certificate, you should surrender that certificate for exchange after the effective time of the merger. Until you surrender your TMBR/Sharp stock certificates, dividends or other distributions declared with a record date after the effective time of the merger will accrue, but will not be paid, on Patterson-UTI Shares that you are entitled to receive as a result of the conversion of your shares of TMBR/Sharp Shares. When you surrender your certificates, any unpaid dividends or other distributions will be paid, less the amount of any withholding taxes that may be required. No interest will be paid or accrued on: - the $9.09 in cash being paid per TMBR/Sharp Share surrendered to the exchange agent; - the amount of cash being paid in lieu of fractional Patterson-UTI Shares; or - any cash dividends and any other dividends or other distributions declared by Patterson-UTI on Patterson-UTI Shares with a record date after the effective time of the merger and a payment date on or before the date the relevant TMBR/Sharp stock certificate was surrendered. The exchange agent will deliver to Patterson-UTI any Patterson-UTI Shares to be issued in the merger or funds set aside by Patterson-UTI to pay the cash consideration, cash in lieu of fractional shares in connection with the merger or to pay dividends or other distributions on Patterson-UTI Shares to be issued in the merger that are not claimed by former TMBR/Sharp shareholders within one year after the effective time of the merger. Thereafter, Patterson-UTI will act as the exchange agent and former TMBR/ 46 Sharp shareholders may look only to Patterson-UTI for payment of their Patterson-UTI Shares, cash consideration, cash in lieu of fractional shares and unpaid dividends and distributions. None of Patterson-UTI, the surviving company, the exchange agent or any other person will be liable to any former TMBR/Sharp shareholder for any amount properly delivered to a public official pursuant to applicable abandoned property, escheat or similar laws. If any certificates for Patterson-UTI Shares are to be issued in a name other than that in which the TMBR/Sharp stock certificate surrendered in exchange for such shares is registered, the person requesting the exchange must (i) pay any transfer or other taxes required by reason of the issuance of certificates for Patterson-UTI Shares in a name other than that of the registered holder of the certificate surrendered or (ii) establish to the satisfaction of Patterson-UTI or the exchange agent that such tax has been paid or is not applicable. TMBR/SHARP STOCK CERTIFICATES SHOULD NOT BE RETURNED WITH THE ENCLOSED PROXY CARD. A TRANSMITTAL LETTER AND ACCOMPANYING INSTRUCTIONS WILL BE PROVIDED TO TMBR/SHARP SHAREHOLDERS FOLLOWING THE EFFECTIVE TIME OF THE MERGER. FRACTIONAL SHARES No fractional Patterson-UTI Shares will be issued to TMBR/Sharp shareholders. Instead of fractional shares, each TMBR/Sharp shareholder otherwise entitled to a fractional share will receive, in cash rounded to the nearest cent and without interest, an amount representing the fractional share, rounded to four decimal places, multiplied by the average of the midpoint of the daily high and low trading prices of Patterson-UTI Shares as reported under Nasdaq National Market Issues Reports in the Wall Street Journal for each of the first 20 consecutive trading days in the period commencing 25 trading days prior to the closing date of the merger.

ADDITIONAL AGREEMENTS The merger agreement contains additional agreements between Patterson-UTI and TMBR/Sharp relating to, among other things: - convening and holding the TMBR/Sharp shareholder meeting; - making and maintaining the required recommendation by TMBR/Sharp's board of directors to its shareholders; - preparing, filing and distributing this document and filing the registration statement of which this document is a part; - providing access to information and cooperating regarding filings with governmental and other agencies and organizations; - using their commercially reasonable efforts to satisfy the conditions to closing; - providing notice of (i) any representation or warranty in the merger agreement becoming untrue or inaccurate or (ii) the failure to materially comply with or satisfy any covenant, condition or agreement in the merger agreement; - making public announcements; and - listing on the Nasdaq National Market, upon official notice of issuance, the shares of Patterson-UTI to be issued in connection with the merger. 50 EMPLOYEE BENEFIT PLANS Generally, TMBR/Sharp officers and employees at the effective time of the merger who continue as employees of Patterson-UTI or Sub will be immediately eligible to participate in any Patterson-UTI benefit plan that is provided to such persons and will be credited with vesting service for their years of service with TMBR/Sharp. Patterson-UTI will take such actions as are necessary so that each TMBR/Sharp employee who continues as an employee of Patterson-UTI or Sub will not be subject to preexisting condition exclusions or waiting periods for coverages under any Patterson-UTI benefit plan. Patterson-UTI may temporarily retain one or more of TMBR/Sharp's benefit plans to provide for a more efficient transition of TMBR/Sharp employees to Patterson-UTI's benefit plans. Subject to that temporary retention, Patterson-UTI or Sub will provide to each TMBR/Sharp employee who continues as an employee of Patterson-UTI or Sub after the effective time of the merger, compensation and employee benefits that are comparable to the compensation and employee benefits provided to all similarly-situated employees of Patterson-UTI or Sub. INDEMNIFICATION AND INSURANCE From and after the effective time of the merger, Patterson-UTI and the surviving company will indemnify and hold harmless to the fullest extent permitted under applicable law each person who is, or has been at any time prior to the effective time of the merger, an officer or director of TMBR/Sharp and each person who served at the request of TMBR/Sharp as a director, officer, employee or fiduciary of another entity. Those persons will be indemnified to the fullest extent permitted by law against all losses, including fees and expenses of counsel, arising out of or pertaining to actions taken by them, or failures to act, while serving in those capacities, whether claimed before or after the effective time of the merger. The surviving company will maintain directors' and officers' liability insurance for six years after the effective time of the merger to cover persons who are or were covered by TMBR/Sharp's existing directors' and officers' liability insurance policies at any time before the effective time of the merger. The terms of the insurance will be of at least the same coverage and amounts containing terms and conditions that are no less advantageous in any material respect to such persons than the existing insurance with respect to acts or omissions prior to the effective time of the merger. However, the surviving company will not be required to pay annual premiums in excess of 200% of the last annual premium paid by TMBR/Sharp, but will be required to purchase as much coverage as possible for such amount. AFFILIATE AGREEMENTS TMBR/Sharp has agreed to use its best efforts to cause its affiliates, as defined by Rule 145 under the Securities Act of 1933, to deliver to Patterson-UTI written agreements no later than 30 days prior to the effective time of the merger that restrict their ability to sell, transfer or otherwise dispose of any Patterson-UTI Shares issued to them in connection with the merger, except: - in compliance with Rule 145 under the Securities Act of 1933; - pursuant to an effective registration statement under the Securities Act of 1933; or - in reliance upon an opinion of counsel reasonably acceptable to Patterson-UTI, to the effect that such sale, transfer or other disposition is exempt from registration under the Securities Act of 1933. Certain agreements in the merger agreement will survive the effective time of the merger. 51 CONDITIONS PRECEDENT CONDITIONS TO EACH PARTY'S OBLIGATION TO EFFECT THE MERGER The obligations of Patterson-UTI, Sub and TMBR/Sharp to complete the merger are subject to the following conditions: - approval of the merger agreement and the related transactions by the holders of at least two-thirds of the outstanding TMBR/Sharp Shares entitled to vote at the special meeting; - the expiration or termination of the waiting period under the HSR Act (which has occurred) and the filing, occurrence or receipt of other authorizations, consents, orders, or approvals required to consummate the transactions contemplated by the merger agreement; - the absence of any legal restraint or prohibition preventing the consummation of the merger; - the approval for listing of the Patterson-UTI Shares to be issued in the merger on the Nasdaq National Market, upon official notice of issuance; and - a registration statement registering the issuance of the Patterson-UTI Shares shall have become effective, no stop order suspending the effectiveness of the registration statement shall have been issued and remain effective and all necessary state securities or "Blue Sky" authorizations shall have been received. CONDITIONS TO OBLIGATIONS OF PATTERSON-UTI AND SUB Unless waived in whole or in part by Patterson-UTI and Sub, the obligations of Patterson-UTI and Sub to effect the merger are subject to the following conditions: - performance in all material respects by TMBR/Sharp of its obligations under the merger agreement; - certification that each of the representations and warranties of TMBR/Sharp contained in the merger agreement is true and correct in all material respects; - receipt of all required third party authorizations, consents or approvals that, if not received, would have a material adverse effect on the surviving company assuming the merger had taken place; - absence of a material adverse change in TMBR/Sharp's business, operations or financial condition; - holders of no more than five percent (5%) of the outstanding TMBR/Sharp Shares entitled to vote at the special meeting properly perfect their dissenters' rights; - receipt of an opinion of legal counsel to TMBR/Sharp substantially to the effect set forth in exhibit A to the merger agreement attached as Annex A to this proxy statement/prospectus, which form of opinion addresses such matters as organization, existence and good standing, authority, non- contravention, absence of legal proceedings, receipt of required consents and material compliance as to form of the proxy statement/prospectus; - receipt of an opinion satisfactory to Patterson-UTI of its tax counsel, Fulbright & Jaworski L.L.P., to the effect that, if the merger is consummated in accordance with the terms of the merger agreement, the merger will constitute a reorganization within the meaning of Section 368(a) of the Internal Revenue Code; - receipt of a copy of certified resolutions duly adopted by TMBR/Sharp's board of directors approving the merger agreement and the consummation of the merger and the related transactions and directing the submission of the merger to a vote of TMBR/Sharp's shareholders; - receipt of a copy of certified resolutions duly adopted by the holders of at least two-thirds of the outstanding TMBR/Sharp Shares entitled to vote at the special meeting approving the merger agreement and the related transactions; and 52 - receipt of a comfort letter from KPMG LLP, TMBR/Sharp's independent auditors, in form and substance satisfactory to Patterson-UTI and Sub, with respect to the financial statements and certain financial information related to TMBR/Sharp. CONDITIONS TO OBLIGATIONS OF TMBR/SHARP Unless waived in whole or in part by TMBR/Sharp, the obligations of TMBR/Sharp to effect the merger are subject to the following conditions: - performance in all material respects by Patterson-UTI and Sub of their obligations under the merger agreement; - certification that each of Patterson-UTI's and Sub's representations and warranties contained in the merger agreement is true and correct in all material respects; - receipt of all required third party authorizations, consents or approvals that, if not received, would have a material adverse effect on the surviving company assuming the merger had taken place; - absence of a material adverse change in Patterson-UTI's business or operations; - receipt of an opinion of legal counsel to Patterson-UTI and Sub substantially to the effect set forth in exhibit B to the merger agreement attached as Annex A to this proxy/statement prospectus, which form of opinion addresses such matters as organization, existence and good standing; authority, non-contravention, absence of legal proceedings, receipt of required consents, material compliance as to form of the proxy statement/prospectus and legality of the Patterson-UTI Shares to be issued in the merger; - receipt of an opinion satisfactory to TMBR/Sharp of its tax counsel, Haynes and Boone, LLP, to the effect that, if the merger is consummated in accordance with the terms of the merger agreement, the merger will constitute a reorganization within the meaning of Section 368(a) of the Internal Revenue Code; - receipt of a comfort letter from PricewaterhouseCoopers LLP, Patterson-UTI's independent auditors, in form and substance satisfactory to TMBR/Sharp, with respect to the financial statements and certain financial information related to Patterson-UTI and Sub; and - receipt of a copy of certified resolutions duly adopted by Patterson-UTI's board of directors and Sub's managing member approving the merger agreement and the consummation of the merger and the related transactions. Neither Patterson-UTI nor TMBR/Sharp will waive the condition to closing that requires receipt of the tax opinions referenced above. If these opinions are unable to be delivered at the closing of the merger and Patterson-UTI and TMBR/Sharp desire to proceed with a merger other than as a "reorganization" within the meaning of Section 368(a) of the Code, they will do so only after revising the structure of the transaction. In such case, an amended proxy statement/prospectus with revised disclosure regarding the new structure and the material United States federal income tax consequences will be mailed to you at least 20 days prior to the special meeting. If the shareholders have already voted to approve the merger, TMBR/Sharp would hold another special meeting to vote on the revised merger proposal after the amended proxy statement/prospectus had been mailed. See "Material United States Federal Income Tax Consequences" on page 57. NO SOLICITATION TMBR/Sharp has agreed that it will not, and will not permit its officers, directors, employees, investments bankers, attorneys or other advisors, agents and other representatives to, directly or indirectly: - solicit, initiate or encourage, or otherwise intentionally facilitate, the making of any proposal that constitutes a third party "acquisition proposal" of the type described below; 53 - subject to certain exceptions, enter into any agreement with respect to any acquisition proposal; or - participate in any discussions or negotiations regarding, furnish any information with respect to, or facilitate any inquiries or the making of any proposal that constitutes or may reasonably be expected to lead to, an acquisition proposal; provided, however, that: - to the extent required by the fiduciary obligations of the TMBR/Sharp board of directors, as determined in good faith after consultation with outside legal counsel; - before approval of the merger by the TMBR/Sharp shareholders; and - subject to TMBR/Sharp providing written notice to Patterson-UTI of its decision to take such action in response to an unsolicited written request, TMBR/Sharp may: - pursuant to a confidentiality agreement that contains substantially the same terms as the confidentiality agreement contained in the merger agreement, furnish information to, or enter into discussions or negotiations with, any person or entity that has made a superior proposal of the type described below; and - ask for information solely to determine whether or not the unsolicited acquisition proposal is a superior proposal. TMBR/Sharp will promptly notify Patterson-UTI of any pending negotiations relating to, or the receipt of, any acquisition proposal. As used in the merger agreement, "acquisition proposal" means any proposal or offer, other than a proposal or offer by Patterson-UTI or any of its affiliates: - for a merger or other business combination involving TMBR/Sharp; - to acquire from TMBR/Sharp or any of its affiliates in any manner, directly or indirectly, an equity interest in TMBR/Sharp, any voting securities of TMBR/Sharp or a material amount of the assets of TMBR/Sharp; or - to acquire from the TMBR/Sharp shareholders by tender offer, exchange offer or otherwise more than 20% of the outstanding TMBR/Sharp Shares. Except in connection with the termination of the merger agreement as described in "-- Termination" below, the TMBR/Sharp board of directors will not be permitted to: - withdraw, modify, or propose to withdraw or modify its approval or recommendation of the merger agreement or the merger, or - approve or recommend any acquisition proposal, except that: if the TMBR/Sharp board of directors receives an acquisition proposal that, in the exercise of its fiduciary obligations (as determined in good faith by a majority of the disinterested members thereof after consultation with outside legal counsel), it determines to be a superior proposal, the TMBR/Sharp board of directors may withdraw or modify its approval or recommendation of the merger agreement or the merger and may terminate the merger agreement (subject to the conditions in the eleventh through sixteenth bullet points under "-- Termination"), in each case at any time after midnight on the third business day following Patterson-UTI's receipt of written notice of the superior proposal advising Patterson-UTI that the TMBR/Sharp board of directors has received an acquisition proposal which it has determined to be a superior proposal. The notice must specify the material terms and conditions of the superior proposal (including the proposed financing and a copy of any documents conveying the proposal) and identifying the party making the superior proposal. As used in the merger agreement, the term "superior proposal" means any bona fide acquisition proposal to acquire, directly or indirectly, all of the then outstanding TMBR/Sharp Shares or all or substantially all the assets of TMBR/Sharp, and otherwise on terms which a majority of the members of TMBR/Sharp's board of directors determines in its good faith reasonable judgment (after consultation 54 with its financial advisor) to be more favorable to TMBR/Sharp's shareholders than the merger and which it intends to recommend that the TMBR/Sharp shareholders approve. TERMINATION Before the effective time of the merger, the merger agreement may be terminated: - by mutual written consent of Patterson-UTI and TMBR/Sharp, or by mutual action of their respective boards of directors; - by either Patterson-UTI or TMBR/Sharp, if: - the affirmative vote of the holders of two-thirds of the outstanding TMBR/Sharp Shares entitled to vote on the approval of the merger agreement and the related transactions is not obtained upon a vote at the special meeting or an adjournment thereof; - the effective time of the merger has failed to occur on or before December 31, 2003, unless the failure is the result of a material breach of the merger agreement by the party seeking the termination; or - any court or other governmental entity has issued a final and nonappealable order, decree or ruling or has taken any other final and nonappealable action that enjoins, restrains or prohibits the purchase of TMBR/Sharp Shares pursuant to the merger; - by Patterson-UTI, if: - TMBR/Sharp fails to hold and call the TMBR/Sharp shareholder meeting by December 31, 2003; - TMBR/Sharp breaches any of its representations or warranties in, or fails to materially perform any of its covenants, agreements or obligations under, the merger agreement, if such breach or failure (i) would cause any of the conditions to the obligations of all parties to consummate the merger or to the obligations of Patterson-UTI and Sub to consummate the merger not to be satisfied and (ii) cannot be or has not been cured within 30 days following receipt of written notice of such breach; or - TMBR/Sharp's board of directors (i) withdraws or modifies, in any manner adverse to Patterson-UTI, its recommendation or approval of the merger agreement or the related transactions, or (ii) recommends or resolves to recommend to the TMBR/Sharp shareholders an acquisition proposal; - by TMBR/Sharp: - if: - its shareholders have not approved the merger agreement; - it has notified Patterson-UTI of its receipt of a superior proposal; - it has not received by the end of the third business day after receipt of the notice of the superior proposal an offer from Patterson-UTI that is no less favorable than the superior proposal; and - it has paid to Patterson-UTI, a $3.5 million termination fee; or - if Patterson-UTI or Sub breaches any of its representations or warranties in, or fails to materially perform any of its covenants, agreements or obligations under, the merger agreement, if such breach or failure (i) would cause any of the conditions to the obligations of all parties to consummate the merger or to the obligations of TMBR/Sharp to consummate the merger not to be satisfied and (ii) cannot be or has not been cured within 30 days following receipt of written notice of such breach. 55 FEES AND EXPENSES TMBR/Sharp will pay $3.5 million to Patterson-UTI promptly upon: - the termination of the merger agreement: - by Patterson-UTI or TMBR/Sharp, if the TMBR/Sharp shareholders have not voted to approve the merger, and prior to the shareholder meeting, a third party has made a bona fide written acquisition proposal that has not been withdrawn; - by TMBR/Sharp because it receives a superior proposal (which termination must comply with the tenth through sixteenth bullet points under "-- Termination"); or - the TMBR/Sharp board of directors taking any action set forth in the twelfth and thirteenth bullet points under "-- No Solicitation" and not reinstating its recommendation of the merger agreement or withdrawing its approval or recommendation or both of any such acquisition proposal within two business days of taking such actions. Whether or not the merger is consummated, each of Patterson-UTI, Sub and TMBR/Sharp will bear its own costs and expenses in connection with the merger agreement and the related transactions, except that Patterson-UTI and TMBR/Sharp will share equally the costs and expenses in connection with filings and related matters under the HSR Act. AMENDMENT Patterson-UTI, Sub and TMBR/Sharp may amend the merger agreement at any time before the effective time of the merger. However, after the approval of the merger agreement by the TMBR/Sharp shareholders, no amendment may be made that would require further approval by such shareholders without the further approval of such shareholders. EXTENSION; WAIVER Patterson-UTI, Sub and TMBR/Sharp may, at any time before the effective time of the merger and to the extent legally allowed: - extend the time for the performance of any of the obligations or the other acts of the other parties; - waive any inaccuracies in the representations and warranties contained in the merger agreement or in any document delivered pursuant to the merger agreement; or - waive compliance with any of the agreements or conditions contained in the merger agreement. 56 MATERIAL UNITED STATES FEDERAL INCOME TAX CONSEQUENCES The following discussion sets forth the material U.S. federal income tax consequences of the merger. This discussion is based upon the Internal Revenue Code of 1986, as amended (the "Code"), Treasury Regulations promulgated under the Code, court decisions, published positions of the Internal Revenue Service (the "IRS"), and other applicable authorities, all as in effect on the date of this document and all of which are subject to change or differing interpretations, possibly with retroactive effect. This discussion is limited to holders who hold TMBR/Sharp Shares as capital assets for U.S. federal income tax purposes (generally, assets held for investment). This discussion does not address all of the U.S. federal income tax consequences that may be relevant to a holder in light of their particular circumstances or to holders who may be subject to special treatment under U.S. federal income tax laws, such as tax exempt organizations, financial institutions, insurance companies, broker-dealers, holders who hold TMBR/Sharp Shares as part of a hedge, straddle, wash sale, synthetic security, conversion transaction, or other integrated investment comprised of TMBR/Sharp Shares and one or more investments, holders with a "functional currency" (as defined in the Code) other than the U.S. dollar, and persons who acquired TMBR/Sharp Shares in compensatory transactions. Further, this discussion does not address any aspect of state, local or foreign taxation. Except as otherwise indicated, statements of legal conclusion regarding tax treatments, tax effects or tax consequences discussed in this section constitute the opinions of Fulbright & Jaworski L.L.P., counsel to Patterson-UTI, and Haynes and Boone, LLP, counsel to TMBR/Sharp. An opinion of counsel is not binding on the IRS or any court. No ruling has been or will be obtained from the IRS regarding any matter relating to the merger. No assurance can be given that the IRS will not assert, or that a court will not sustain, a position contrary to any of the tax aspects described below. THIS DISCUSSION IS NOT A SUBSTITUTE FOR AN INDIVIDUAL ANALYSIS OF THE TAX CONSEQUENCES OF THE MERGER TO YOU. WE URGE YOU TO CONSULT A TAX ADVISOR REGARDING THE PARTICULAR FEDERAL, STATE, LOCAL AND FOREIGN TAX CONSEQUENCES OF THE MERGER IN LIGHT OF YOUR OWN SITUATION. As used in this section, a "U.S. holder" is (i) an individual U.S. citizen or resident alien; (ii) a corporation, partnership or other entity created or organized under U.S. law (federal or state); (iii) an estate whose worldwide income is subject to U.S. federal income tax; or (iv) a trust if a court within the U.S. is able to exercise primary supervision over the administration of the trust and one or more U.S. persons have the authority to control all substantial decisions of the trust. A "non-U.S. holder" is any holder other than a U.S. holder. This discussion does not address the U.S. federal income tax consequences to non-U.S. holders that are subject to special treatment under U.S. federal income tax laws, such as (i) a non-U.S. holder that holds TMBR/Sharp Shares in connection with a trade or business conducted in the United States or in connection with an office or fixed place of business located in the United States, (ii) an individual non-U.S. holder that is deemed to be present in the United States for 183 days or more in the current taxable year, (iii) an individual non-U.S. holder that is an expatriate subject to the provisions of Section 877 of the Code, (iv) a non-U.S. holder that is subject to or affected by the provisions of an income tax treaty to which the United States is a party, or (v) a non-U.S. holder that owns or has owned (either directly or indirectly) more than five percent (5%) of the outstanding shares of Patterson-UTI Shares at any time during the five (5) year period preceding the effective time of the merger. If a partnership (including for this purpose any entity treated as a partnership for U.S. federal income tax purposes) is a beneficial owner of TMBR/Sharp Shares, the tax treatment of a partner in such partnership will generally depend on the status of the partner and the activities of the partnership. Holders of TMBR/Sharp Shares that are partnerships and partners in such partnerships are urged to consult their tax advisors regarding the U.S. federal income tax consequences of owning and disposing of TMBR/Sharp Shares in the merger. Patterson-UTI and TMBR/Sharp have made representations to both tax counsels, including a representation that holders of TMBR/Sharp Shares will receive in the merger an amount of 57 Patterson-UTI Shares with a value equal to at least forty percent (40%) of the total consideration paid by Patterson-UTI for all TMBR/Sharp Shares. The total consideration takes into account the amount of cash paid or deemed to be paid to holders of TMBR/Sharp Shares in connection with the merger, cash paid to holders of TMBR/Sharp Shares who perfect their dissenters' rights and cash paid by Patterson-UTI to acquire TMBR/Sharp Shares within twelve (12) months of the date of the merger agreement. Based in part on such representations, it is the opinion of Fulbright & Jaworski L.L.P., tax counsel for Patterson-UTI, and Haynes and Boone, LLP, tax counsel for TMBR/Sharp, that the merger when effected in accordance with the terms of the merger agreement, will be treated for United States federal income tax purposes as a "reorganization" within the meaning of Section 368(a) of the Internal Revenue Code. TAX CONSEQUENCES OF THE MERGER TO U.S. HOLDERS THE MERGER The following discussion sets forth the material United States federal income tax consequences to U.S. holders in a merger that qualifies as a "reorganization" within the meaning of Section 368(a) of the Code. A U.S. holder who exchanges TMBR/Sharp Shares for shares of Patterson-UTI Shares and cash in the merger will recognize gain (but not loss) in an amount equal to the lesser of (i) the amount of cash received pursuant to the merger, and (ii) the amount, if any, by which (a) the sum of the fair market value of the Patterson-UTI Shares as of the effective time of the merger and the amount of cash received pursuant to the merger exceeds (b) such U.S. holder's adjusted tax basis in such holder's TMBR/Sharp Shares. Gain recognized upon the exchange generally will be capital gain, unless the receipt of cash by a U.S. holder has the effect of a distribution of a dividend, in which case the gain will be treated as dividend income to the extent of the U.S. holder's ratable share of TMBR/Sharp's accumulated earnings and profits as calculated for U.S. federal income tax purposes. In determining whether or not the receipt of cash has the effect of a distribution of a dividend, certain constructive ownership rules must be taken into account. Any recognized capital gain will be long-term capital gain if the U.S. holder has held TMBR/Sharp Shares for more than one year. If a U.S. holder receives cash in lieu of a fractional share of Patterson-UTI Shares in exchange for shares of Patterson-UTI Shares, such U.S. holder will generally recognize capital gain or loss equal to the difference between the cash received in lieu of such fractional share and the portion of such U.S. holder's adjusted tax basis in TMBR/Sharp Shares surrendered that is allocable to such fractional share. The capital gain or loss will be long-term capital gain or loss if the holding period for TMBR/Sharp Shares exchanged for cash in lieu of the fractional share of Patterson-UTI stock is more than one year at the time of the merger. A U.S. holder will have an aggregate tax basis in the shares of Patterson-UTI Shares received pursuant to the merger equal to the aggregate adjusted tax basis in TMBR/Sharp Shares surrendered pursuant to the merger, (i) reduced by (a) the portion of such U.S. holder's adjusted tax basis in TMBR/Sharp shares surrendered in the merger that is allocable to a fractional share of Patterson-UTI Shares for which cash is received, and (b) the amount of cash received by such U.S. holder pursuant to the merger, and (ii) increased by the amount of gain (including the portion of such gain that is treated as a dividend as described above) recognized by such U.S. holder (but not by any gain recognized upon the receipt of cash in lieu of a fractional share of Patterson-UTI Shares pursuant to the merger). The holding period of the Patterson-UTI Shares received by a U.S. holder pursuant to the merger will include the holding period of TMBR/Sharp Shares surrendered in exchange therefor, provided that such TMBR/Sharp Shares are held as capital assets of the effective time of the merger. One of the requirements that must be satisfied in order for the merger to qualify as a "reorganization" under Section 368(a) of the Code is the continuity of interest requirement. This requirement will be satisfied if the shareholders of TMBR/Sharp exchange a substantial portion of their proprietary interest in TMBR/Sharp for proprietary interests in Patterson-UTI. In the opinion of Haynes and Boone, LLP and of 58 Fulbright & Jaworski L.L.P., the continuity of interest requirement will be satisfied under applicable case law if, as of the effective time of the merger, the value of the Patterson-UTI Shares received in connection with the merger by the shareholders of TMBR/Sharp equals or exceeds forty percent (40%) of the total consideration paid or deemed paid by Patterson-UTI in exchange for all TMBR/Sharp Shares, taking into account the amount of cash paid or deemed paid to holders of TMBR/Sharp Shares in connection with the merger, cash paid to TMBR/Sharp shareholders who perfect their dissenters' rights and cash paid by Patterson-UTI to acquire TMBR/Sharp Shares within twelve (12) months of the date of the merger agreement. Various factors affect whether the value of the Patterson-UTI Shares received by the shareholders of TMBR/Sharp in exchange for TMBR/Sharp Shares is equal to at least forty percent (40%) of the combined value of the total consideration paid by Patterson-UTI for all TMBR/Sharp Shares, including: - the amount, if any, to be paid to shareholders of TMBR/Sharp who perfect their dissenters' rights; - whether prior to and in connection with the merger TMBR/Sharp (or certain parties related to TMBR/Sharp) redeems or acquires TMBR/Sharp Shares or makes distributions to the shareholders of TMBR/Sharp; and - whether there will be any repurchases by Patterson-UTI (or certain parties related to Patterson-UTI) of the Patterson-UTI Shares to be issued in the merger. Accordingly, it may not be possible to state with any certainty the minimum trading price of the Patterson-UTI Shares at which the value of the Patterson-UTI Shares to be received in the merger will be equal to at least forty percent (40%) of the value of the total consideration paid by Patterson-UTI for all TMBR/Sharp Shares. Holders of TMBR/Sharp Shares are entitled to dissenters' rights under Texas law in connection with the merger. If a U.S. holder receives cash pursuant to the exercise of dissenters' rights, that U.S. holder generally will recognize gain or loss measured by the difference between the cash received and such holder's adjusted tax basis in such holder's TMBR/Sharp Shares. This gain should be long-term capital gain or loss if the U.S. holder held TMBR/Sharp Shares for more than one year at the time at which any cash is received. Any holder of TMBR/Sharp Shares that plans to exercise dissenters' rights in connection with the merger is urged to consult a tax advisor to determine the related tax consequences. However, if the IRS were to successfully challenge the conclusion that the merger is treated as a "reorganization" within the meaning of Section 368(a) of the Code, then each U.S. holder would recognize gain or loss equal to the difference between the sum of the fair market value of the Patterson-UTI Shares and the amount of cash received in the merger (including cash received in lieu of fractional shares of Patterson-UTI Shares) and such U.S. holder's tax basis in TMBR/Sharp Shares surrendered in exchange therefor. Further, if the merger is not treated as a "reorganization" within the meaning of Section 368(a) of the Code, TMBR/Sharp would be subject to tax on the deemed sale of its assets to Patterson-UTI with gain or loss for this purpose measured by the difference between TMBR/Sharp's tax basis in its assets and the fair market value of the consideration deemed to be received therefor (i.e., the cash and Patterson-UTI Shares). Such gain or loss would be reported on TMBR/Sharp's final tax return, subject to the effect of any tax carryovers and the effect of its other income or loss for such period, and Patterson-UTI would become liable for any such tax liability by virtue of the merger. BACKUP WITHHOLDING United States federal income tax law requires that a holder of TMBR/Sharp Shares provide the exchange agent with his correct taxpayer identification number, which is, in the case of a holder who is an individual, a social security number, or, in the alternative, establish a basis for exemption from backup withholding. Exempt holders, including, among others, corporations and some foreign individuals, are not subject to backup withholding and reporting requirements. If the correct taxpayer identification number or an adequate basis for exemption is not provided, a holder will be subject to backup withholding. Any amounts withheld under the backup withholding rules from a payment to a U.S. holder will be allowed as 59 a credit against such U.S. holder's U.S. federal income tax and may entitle the U.S. holder to a refund, provided that the required information is furnished to the IRS. To prevent backup withholding, each holder of TMBR/Sharp Shares must complete the Substitute Form W-9 which will be provided by the exchange agent with the transmittal letter and certify under penalties of perjury that (i) the taxpayer identification number provided is correct or that the holder is awaiting a taxpayer identification number; and (ii) the holder is not subject to backup withholding because (a) the holder is exempt from backup withholding, (b) the holder has not been notified by the IRS that he is subject to backup withholding as a result of the failure to report all interest or dividends, or (c) the IRS has notified the holder that he is no longer subject to backup withholding. The Substitute Form W-9 must be completed, signed and returned to the exchange agent. INFORMATION REPORTING Shareholders of TMBR/Sharp receiving Patterson-UTI Shares in the merger should file a statement with their U.S. federal income tax return setting forth their adjusted tax basis in TMBR/Sharp Shares exchanged in the merger, as well as the fair market value of the Patterson-UTI Shares and the amount of cash received in the merger. In addition, shareholders of TMBR/Sharp will be required to retain permanent records of these facts relating to the merger. TAX CONSEQUENCES OF THE MERGER TO NON-U.S. HOLDERS This discussion does not address the U.S. federal income tax consequences to non-U.S. holders that are subject to the special rules described above. THE MERGER Provided that TMBR/Sharp has not been a U.S. real property holding corporation within the meaning of Section 897(c) of the Code (a "USRPHC") within the 5-year period ending on the date of the merger, a non-U.S. holder generally will not be subject to U.S. federal income tax on gain or income realized on the exchange of TMBR/Sharp Shares for Patterson-UTI Shares and cash, unless, (i) in the case of an individual non-U.S. holder, such holder either (a) is present in the U.S. for 183 days or more in the year of such exchange, or (b) has gain from the exchange of TMBR/Sharp Shares that is attributable to an office or other fixed place of business in the U.S., and (ii) in the case of a corporate non-U.S. holder, such holder has gain from the exchange of TMBR/Sharp Shares that is attributable to an office or other fixed place of business in the U.S. A corporate non-U.S. holder may also, under certain circumstances, be subject to an additional branch profits tax with respect to gain that is effectively connected with the conduct of a trade or business in the United States. TMBR/Sharp believes that it has not been a USRPHC during the relevant 5-year period. Even if it is determined that TMBR/Sharp has been a USRPHC during the relevant 5-year period, a non-U.S. holder not described in the preceding sentence will not be subject to U.S. federal income tax on any such gain or income provided that such holder does not actually or constructively own 5% or more of the outstanding TMBR/Sharp Shares on the date of the merger. BACKUP WITHHOLDING In general, backup withholding and information reporting will not apply to payments made by us or our paying agents in their capacities as such to a non-U.S. holder if the holder has provided the required certification that the holder is not a U.S. person on IRS Form W-8BEN, IRS Form W-8ECI, IRS Form W-8EXP, or IRS Form W-8IMY, as applicable, and provided that neither we nor our paying agent has actual knowledge that the holder is a U.S. person. Payments of the proceeds from a disposition by a non-U.S. holder of TMBR/Sharp Shares made to or through a foreign office of a broker will generally not be subject to information reporting or backup withholding. However, information reporting will apply to those payments, if the broker is: (i) a U.S. person, (ii) a controlled foreign corporation for U.S. federal income tax purposes, (iii) a foreign person 50% or more of whose gross income from all sources is 60 effectively connected with a U.S. trade or business for a specified three-year period, or (iv) a foreign partnership, if at any time during its tax year, one or more of its partners are U.S. persons, as defined in Treasury Regulations, who in the aggregate hold more than 50% of the income or capital interest in the partnership or if, at any time during its tax year, the foreign partnership is engaged in a U.S. trade or business, unless (a) such broker has documentary evidence in its records that the beneficial owner is not a U.S. person and certain other conditions are met or (b) the beneficial owner otherwise establishes an exemption. Payments of the proceeds from a disposition by a non-U.S. holder made to or through the U.S. office of a broker is subject to information reporting and backup withholding unless the statement that the payee is not a U.S. person described above has been received (and the payor does not have actual knowledge that the beneficial owner is a U.S. person) or the holder or beneficial owner otherwise establishes an exemption from information reporting and backup withholding. Any amounts withheld under the backup withholding rules from a payment to a non-U.S. holder will be allowed as a credit against such non-U.S. holder's U.S. federal income tax and may entitle the non-U.S. holder to a refund, provided that the required information is furnished to the IRS. 61 DESCRIPTION OF PATTERSON-UTI CAPITAL STOCK The following summary description of our capital stock is qualified in its entirety by the provisions of Patterson-UTI's restated certificate of incorporation and amended and restated bylaws and by Delaware law. GENERAL Patterson-UTI is authorized by its restated certificate of incorporation to issue 200,000,000 shares of common stock, $0.01 par value per share, and 1,000,000 shares of preferred stock, $0.01 par value per share, of which 100,000 have been designated as Series A Participating Preferred Stock. COMMON STOCK VOTING RIGHTS The holders of Patterson-UTI Shares are entitled to one vote for each share held of record on all matters submitted to a vote of stockholders, including the election of directors. Holders of Patterson-UTI Shares do not have cumulative voting rights. DIVIDENDS The holders of Patterson-UTI Shares are entitled to receive dividends when, as and if declared by the Patterson-UTI board of directors out of funds legally available therefor. However, if any shares of Patterson-UTI preferred stock are at the time outstanding, the payment of dividends on Patterson-UTI Shares or other distributions (including Patterson-UTI's repurchase of Patterson-UTI Shares) will be subject to the declaration and payment of all cumulative dividends on outstanding shares of Patterson-UTI preferred stock. LIQUIDATION In the event of the dissolution, liquidation or winding up of Patterson-UTI, the holders of Patterson-UTI Shares will be entitled to share ratably in any assets remaining after the satisfaction in full of the prior rights of creditors, including holders of Patterson-UTI indebtedness, and the payment of the aggregate liquidation preference of the preferred stock. OTHER RIGHTS The holders of Patterson-UTI Shares do not have any conversion, redemption or preemptive rights. TRANSFER AGENT AND REGISTRAR The transfer agent and registrar for Patterson-UTI Shares is Continental Stock Transfer & Trust Company, New York, New York. LISTING Outstanding Patterson-UTI Shares are traded on the Nasdaq National Market under the symbol "PTEN". PREFERRED STOCK The Patterson-UTI board of directors can, without approval of its stockholders, issue one or more additional series of preferred stock and determine the number of shares of each series and the rights, preferences and limitations of each series by appropriate board resolutions. The terms of the preferred stock will be subject to and qualified by the certificate of designation relating to any applicable series of preferred stock. Undesignated preferred stock may enable the Patterson-UTI board of directors to render more difficult or to discourage an attempt to obtain control of Patterson-UTI by means of a tender offer, proxy contest, merger or otherwise, and to thereby protect the continuity of Patterson-UTI's management. As a result, the issuance of shares of a series of preferred stock may discourage bids for Patterson-UTI 62 Shares or may otherwise adversely affect the market price of Patterson-UTI Shares or any other of Patterson-UTI preferred stock. The issuance of shares of preferred stock may also adversely affect the rights of the holders of Patterson-UTI Shares. For example, any preferred stock issued may rank prior to Patterson-UTI Shares as to dividend rights, liquidation preference or both, may have full or limited voting rights and may be convertible into Patterson-UTI Shares or other securities. STOCKHOLDER RIGHTS PLAN The Patterson-UTI board of directors has adopted a stockholder rights plan, which provides each Patterson-UTI Share's holder a preferred share purchase right (the "Rights"). The Rights permit the holder to purchase one one-thousandth of a share (a unit) of Series A preferred stock at an initial exercise price of $75 per share under certain circumstances. The purchase price, the number of units of preferred stock and the type of securities issuable upon exercise of the Rights are subject to adjustment. The Rights expire on October 23, 2011 unless earlier redeemed or exchanged. Until a Right is exercised, the holder thereof has no rights as a stockholder of Patterson-UTI, including the right to vote or receive dividends. The Rights become exercisable on the earlier to occur of (i) the acquisition by a person or group of affiliated or associated persons of 15% or more of the outstanding Patterson-UTI Shares, or (ii) 10 business days following the commencement of or announcement of an intention to acquire 15% or more of the outstanding Patterson-UTI Shares through a tender offer or exchange offer. OTHER PROVISIONS HAVING A POSSIBLE ANTI-TAKEOVER EFFECT SECTION 203 OF DGCL As a Delaware corporation, Patterson-UTI is subject to Section 203 of the DGCL. Subject to limited exceptions, Section 203 of the DGCL prohibits "business combinations," including certain mergers, sales and leases of assets, issuances of securities and similar transactions by a corporation or a subsidiary with an "interested stockholder" who beneficially owns 15% or more of a corporation's voting stock, within three years after the person or entity becomes an interested stockholder, unless: (1) the transaction that will cause the person to become an interested stockholder is approved by the board of directors of the corporation prior to the transaction, (2) after the completion of the transaction in which the person becomes an interested stockholder, the interested stockholder holds at least 85% of the voting stock of the corporation not including (a) shares held by officers and directors of the interested stockholder and (b) shares held by specified employee benefit plans, or (3) at or subsequent to such time the person becomes an interested stockholder, the business combination is approved by the board of directors and holders of at least 66 2/3% of the outstanding voting stock, excluding shares held by the interested stockholder. In addition to being subject to Section 203 of the DGCL, Patterson-UTI's restated certificate of incorporation and amended and restated bylaws contain certain provisions that could discourage potential takeover attempts and make more difficult attempts by stockholders to change management. The following paragraphs set forth a summary of these provisions: SPECIAL MEETINGS OF STOCKHOLDERS The Patterson-UTI restated certificate of incorporation provides that special meetings of stockholders may be called only by the Patterson-UTI board of directors (or a majority of the members thereof), the chief executive officer, the president or the holders of a majority of the outstanding stock entitled to vote at such special meeting. This provision will make it more difficult for Patterson-UTI stockholders to call a special meeting. NO STOCKHOLDER ACTION BY WRITTEN CONSENT The Patterson-UTI restated certificate of incorporation provides that stockholder action may be taken only at annual or special meetings and not by written consent of the stockholders. 63 COMPARISON OF THE RIGHTS OF PATTERSON-UTI STOCKHOLDERS AND TMBR/SHARP SHAREHOLDERS As a result of the merger, the holders of TMBR/Sharp Shares will become holders of Patterson-UTI Shares. The rights of TMBR/Sharp's shareholders are currently governed by the TBCA and the articles of incorporation and bylaws of TMBR/Sharp. The rights of Patterson-UTI's stockholders are governed by the DGCL and the restated certificate of incorporation and amended and restated bylaws of Patterson-UTI. The following is a summary of material differences between the rights of TMBR/Sharp shareholders and Patterson-UTI stockholders. Because TMBR/Sharp is a Texas corporation and Patterson-UTI is a Delaware corporation, these differences arise from differences between the TBCA and the DGCL in addition to differences between the articles of incorporation and bylaws of TMBR/Sharp and the restated certificate of incorporation and amended and restated bylaws of Patterson-UTI. The following summaries are qualified in their entirety by reference to the TBCA and DGCL and the governing corporate instruments of TMBR/Sharp and Patterson-UTI to which you are referred. The identification of specific differences in the rights of these holders as material is not intended to indicate that other equally important or more significant differences do not exist.

A-5 AGREEMENT AND PLAN OF MERGER This Agreement and Plan of Merger is dated as of May 26, 2003, among Patterson-UTI Energy, Inc., a Delaware corporation ("Parent"), Patterson-UTI Acquisition, LLC, a Texas limited liability company ("Sub") and a wholly owned subsidiary of Parent, and TMBR/Sharp Drilling, Inc., a Texas corporation (the "Company"). WHEREAS, the respective Boards of Directors of each of Parent and the Company, and the sole member of Sub, have approved the acquisition of the Company by Parent on the terms and subject to the conditions of this Agreement and Plan of Merger (this "Agreement"); WHEREAS, in order to effect such acquisition of the Company, the respective Boards of Directors of each of Parent and the Company, and the sole member of Sub, have approved the merger of the Company with and into Sub (the "Merger"), upon the terms and subject to the conditions of this Agreement, whereby each issued and outstanding share of common stock, $.10 par value per share, of the Company (singularly, "Company Share", and plurally, "Company Shares") not owned directly or indirectly by Parent or the Company, except Company Shares held by persons who object to the Merger and comply with all of the provisions of Texas law concerning the right of holders of Company Shares to dissent from the Merger and require appraisal of their Company Shares ("Dissenting Shareholders") will be converted into the right to receive $9.09 in cash and 0.312166 of a share of common stock, $0.01 par value per share, of Parent (the "Parent Common Stock"); WHEREAS, the parties intend that the Merger will qualify as a reorganization described in Section 368(a) of the Internal Revenue Code of 1986, as amended (the "Code"); and WHEREAS, Parent, Sub and the Company desire to make certain representations, warranties and agreements in connection with the Merger and also to prescribe various conditions to the Merger; NOW, THEREFORE, in consideration of the premises and the representations, warranties and agreements herein contained, the parties agree as follows: ARTICLE 1 THE MERGER 1.1 The Merger. Upon the terms and subject to the conditions hereof and in accordance with the Texas Business Corporation Act (the "TBCA"), the Company shall be merged with and into Sub at the Effective Time (as defined below). Following the Merger, the separate corporate existence of the Company shall cease and Sub shall continue as the Surviving Company (the "Surviving Company") and shall succeed to and assume all the rights and obligations of the Company in accordance with the TBCA. 1.2 Effective Time. As soon as practicable following the satisfaction or waiver of the conditions set forth in ARTICLE 6, the parties shall file articles of merger or other appropriate documents with the Secretary of State of Texas (the "Articles of Merger") executed in accordance with the relevant provisions of the TBCA. The Merger shall become effective at such time as the Articles of Merger are duly filed with the Secretary of State of Texas or at such other time as Parent, Sub and the Company shall agree should be specified in the Articles of Merger (the time the Merger becomes effective being the "Effective Time"). 1.3 Effects of the Merger. The Merger shall have the effects set forth in Article 5.06 of the TBCA. 1.4 Articles of Organization and Regulations. (a) The Articles of Organization of Sub, as in effect at the Effective Time, shall be the Articles of Organization of the Surviving Company until thereafter changed or amended as provided therein or by applicable law, provided that such Articles of Organization shall be amended hereby as of the Effective Time to change the name of the Surviving Company to TMBR/Sharp Drilling, LLC. A-6 (b) The regulations of Sub as in effect at the Effective Time shall be the regulations of the Surviving Company until thereafter changed or amended as provided therein or by applicable law. 1.5 Officers. The officers of Sub at the Effective Time shall be the officers of the Surviving Company and shall hold office until the earlier of their resignation or removal or until their respective successors are duly elected and qualified, as the case may be. 1.6 Further Assurances. If at any time after the Effective Time, the Surviving Company shall consider or be advised that any deeds, bills of sale, assignments or assurances or any other acts or things are necessary, desirable or proper (a) to vest, perfect or confirm, of record or otherwise, in the Surviving Company, its right, title or interest in, to or under any of the rights, privileges, powers, franchises, properties or assets of either of the constituent corporations to the Merger or (b) otherwise to carry out the purposes of this Agreement, the Surviving Company and its appropriate officers and directors or their designees shall be authorized to execute and deliver, in the name and on behalf of either of the constituent corporations to the Merger, all such deeds, bills of sale, assignments and assurances and do, in the name and on behalf of such constituent corporations, all such other acts and things necessary, desirable or proper to vest, perfect or confirm its right, title or interest in, to or under any of the rights, privileges, powers, franchises, properties or assets of such constituent corporation and otherwise to carry out the purposes of this Agreement. 1.7 Closing. The closing of the transactions contemplated by this Agreement (the "Closing") shall take place at the offices of Fulbright & Jaworski L.L.P., 1301 McKinney Street, Suite 5100, Houston, Texas 77010, at 10:00 a.m., Houston time, on the second business day after the day on which the last of the conditions set forth in ARTICLE 6 shall have been fulfilled or waived or at such other time and place as Parent, Sub and the Company shall agree. ARTICLE 2 EFFECT OF THE MERGER ON THE CAPITAL STOCK AND MEMBERSHIP INTERESTS OF THE CONSTITUENT COMPANIES; EXCHANGE OF CERTIFICATES 2.1 Effect on Capital Stock and Membership Interests. As of the Effective Time, by virtue of the Merger and without any action on the part of the holders of any of the Company Shares: (a) Membership Interests of Sub. Each issued and outstanding membership interest of Sub shall be converted into and become an equivalent fully paid and nonassessable membership interest of the Surviving Company. (b) Cancellation of Treasury Shares and Parent Owned Shares. All Company Shares that are owned directly or indirectly by the Company as treasury stock and any Company Shares owned by Parent, Sub or any other wholly owned subsidiary of Parent shall be canceled, and no consideration shall be delivered in exchange therefor. (c) Conversion of Company Shares. Subject to the provisions of Sections 2.1(e), 2.1(f) and 2.4, each Company Share issued and outstanding immediately prior to the Effective Time (other than shares to be canceled in accordance with Section 2.1(b)) shall be converted into $9.09 in cash (the "Cash Consideration") and 0.312166 (the "Exchange Ratio") of a validly issued, fully paid and nonassessable share of Parent Common Stock (collectively, the "Merger Consideration"). Pursuant to the Rights Agreement between Parent and Continental Stock Transfer & Trust Company, as Rights Agent, dated January 2, 1997, as amended ("Parent Rights Agreement"), each share of Parent Common Stock shall be accompanied by a right under the Parent Rights Agreement. All Company Shares, when so converted, shall no longer be outstanding and shall automatically be canceled and retired and each holder of a Certificate (as defined in Section 2.2(a)) representing any such shares shall cease to have any rights with respect thereto, except the right to receive certain dividends and other distributions as contemplated by Section 2.3, the Cash Consideration, shares of Parent Common A-7 Stock and any cash, without interest, in lieu of fractional shares to be issued or paid in consideration therefor upon the surrender of such Certificate in accordance with Section 2.2. (d) Treatment of Stock Options. Each outstanding Company Stock Option (as defined in Section 5.9) shall be treated as provided in Section 5.9. (e) Dissenting Shares. Notwithstanding anything in this Agreement to the contrary, Company Shares that are outstanding immediately prior to the Effective Time and that are held by Dissenting Shareholders who shall have perfected dissenters' rights in accordance with Article 5.12 of the TBCA (the "Dissenting Shares") shall not be converted into or represent the right to receive the Merger Consideration (but instead shall be converted into the right to receive payment from the Surviving Company with respect to such Dissenting Shares in accordance with the TBCA), unless and until such Dissenting Shareholder shall have failed to perfect or shall have effectively withdrawn or lost such holder's rights to appraisal under the TBCA. If any such Dissenting Shareholder shall have failed to perfect or shall have effectively withdrawn or lost such holder's rights to appraisal of such Company Shares under the TBCA, such Dissenting Shareholder's Company Shares shall thereupon be deemed to have been converted into and to have become exchangeable for, at the Effective Time, the right to receive, upon surrender as provided above, the Merger Consideration for the Certificate or Certificates that formerly evidenced such Company Shares. The Company shall, prior to the Effective Time, use all reasonable efforts to give Parent and Sub prompt notice of any written demands for payment of the fair value of any Company Shares, withdrawals of such demands, and any other instruments served on the Company pursuant to the TBCA received by the Company relating to shareholders' rights of appraisal. Except with the prior written consent of Parent and Sub, the Company shall not voluntarily make any payment with respect to any demands for appraisal, or settle or offer to settle any such demands. (f) Adjustment of Exchange Ratio. In the event of any reclassification, recapitalization, stock split, stock combination, stock dividend or share exchange with respect to Parent Common Stock or Company Shares, as the case may be, (or if a record date with respect to any of the foregoing should occur) subsequent to the date of this Agreement but prior to the Effective Time, appropriate and proportionate adjustments, if any, shall be made to the Exchange Ratio, and all references to the Exchange Ratio in this Agreement shall be deemed to be the Exchange Ratio as so adjusted. 2.2 Surviving Company to Make Certificates Available. (a) Exchange of Certificates. The Company and Parent shall authorize Continental Stock Transfer & Trust Company, New York, New York (or such other person or persons as shall be reasonably acceptable to the Company and Parent) to act as Exchange Agent hereunder (the "Exchange Agent"). As soon as practicable after the Effective Time, Sub shall deposit with the Exchange Agent for the benefit of the holders of certificates, which immediately prior to the Effective Time represented Company Shares (the "Certificates"), the Cash Consideration and certificates representing the shares of Parent Common Stock (such Cash Consideration and shares of Parent Common Stock, together with any dividends or distributions with respect thereto payable as provided in Section 2.3, being hereinafter referred to as the "Exchange Fund") issuable pursuant to Section 2.1(c) in exchange for outstanding Company Shares. (b) Exchange Procedures. Promptly after the Effective Time, the Exchange Agent shall mail to each holder of record of a Certificate whose shares were converted pursuant to Section 2.1 into shares of Parent Common Stock a letter of transmittal (which shall specify that delivery shall be effected, and risk of loss and title to the Certificates shall pass, only upon actual and proper delivery of the Certificates to the Exchange Agent and shall contain instructions for use in effecting the surrender of the Certificates in exchange for the Cash Consideration and certificates representing shares of Parent Common Stock and shall be in such form and contain such other provisions as the Company and Parent may reasonably specify). Upon surrender of a Certificate for cancellation to the Exchange Agent, together with such letter of transmittal, duly executed, the holder of such Certificate shall be entitled to receive in exchange therefor the Cash Consideration and a certificate representing that number of whole shares of Parent Common Stock which such holder has the right to receive pursuant to this Article 2, and the Certificate A-8 so surrendered shall forthwith be canceled. Until surrendered as contemplated by this Section 2.2, each Certificate shall, at and after the Effective Time, be deemed to represent only the right to receive, upon surrender of such Certificate, the Cash Consideration, the certificate representing the appropriate number of shares of Parent Common Stock, cash in lieu of fractional shares, if any, as provided in Section 2.4 and certain dividends and other distributions as contemplated by Section 2.3. 2.3 Dividends; Transfer Taxes. No dividends or other distributions that may be declared on or after the Effective Time on Parent Common Stock or are payable to the holders of record thereof on or after the Effective Time will be paid to persons entitled by reason of the Merger to receive certificates representing Parent Common Stock until such persons surrender their Certificates, as provided in Section 2.2, and no Cash Consideration or cash payment in lieu of fractional shares shall be paid to any such holder pursuant to Section 2.4 until such holder of such Certificate shall so surrender such Certificate. Subject to the effect of applicable law, there shall be paid to the record holder of the certificates representing such Parent Common Stock (a) at the time of such surrender or as promptly as practicable thereafter, the amount of any dividends or other distributions theretofore paid with respect to whole shares of such Parent Common Stock and having a record date on or after the Effective Time and a payment date prior to such surrender and (b) at the appropriate payment date or as promptly as practicable thereafter, the amount of dividends or other distributions payable with respect to whole shares of Parent Common Stock and having a record date on or after the Effective Time but prior to surrender and a payment date subsequent to surrender. In no event shall the person entitled to receive such dividends or other distributions be entitled to receive interest on such dividends or other distributions. If any cash or certificate representing shares of Parent Common Stock is to be paid to or issued in a name other than that in which the Certificate surrendered in exchange therefor is registered, it shall be a condition of such exchange that the Certificate so surrendered shall be properly endorsed and otherwise in proper form for transfer and that the person requesting such exchange shall pay to the Exchange Agent any transfer or other taxes required by reason of the issuance of certificates for such shares of Parent Common Stock in a name other than that of the registered holder of the Certificate surrendered, or shall establish to the satisfaction of the Exchange Agent that such tax has been paid or is not applicable. 2.4 No Fractional Shares. No certificates or scrip representing fractional shares of Parent Common Stock shall be issued upon the surrender for exchange of Certificates pursuant to this Article 2, and no Parent dividend or other distribution or stock split or combination shall relate to any fractional security, and such fractional interests shall not entitle the owner thereof to vote or to any rights of a security holder of Parent. In lieu of any such fractional securities, each holder of Company Shares who would otherwise have been entitled to receive a fraction of a share of Parent Common Stock (after taking into account all Company Shares then held of record by such holder) shall receive cash (without interest) in an amount equal to the product of such fractional part of a share of Parent Common Stock multiplied by the Closing Price and rounded to the nearest cent. As used in this Agreement, (a) "Closing Price" means the average of the midpoint of the daily high and low trading prices of Parent Common Stock, rounded to four decimal places, as reported under Nasdaq National Market Issues Reports in The Wall Street Journal for each of the first 20 consecutive Trading Days in the period commencing twenty-five (25) Trading Days prior to the date of the Closing and (b) "Trading Day" means a day on which the National Association of Securities Dealers, Inc. National Market ("Nasdaq National Market") is open for trading. 2.5 Return of Exchange Fund. Any portion of the Exchange Fund that remains undistributed to the former shareholders of the Company for one year after the Effective Time shall be delivered to Parent, upon demand of Parent, and any former shareholders of the Company who have not theretofore complied with this Article 2 shall thereafter look only to Parent for payment of their claim for Parent Common Stock, Cash Consideration, any cash in lieu of fractional shares of Parent Common Stock and any dividends or distributions with respect to Parent Common Stock. None of the Company, Parent nor the Surviving Company shall be liable to any holder of Company Shares for shares (or dividends or distributions with respect thereto) or cash in lieu of fractional shares of Parent Common Stock delivered to a public official pursuant to any applicable abandoned property, escheat or similar law. A-9 2.6 Further Ownership Rights in Company Common Stock. All shares of Parent Common Stock issued upon the surrender for exchange of Certificates in accordance with the terms hereof (including any cash paid pursuant to Sections 2.3 or 2.4) shall be deemed to have been issued in full satisfaction of all rights pertaining to the Company Shares, subject, however, to the Surviving Company's obligation to pay any dividends or make any other distribution with a record date prior to the Effective Time which may have been declared or made by the Company on Company Shares in accordance with the terms of this Agreement. 2.7 Closing of the Company Transfer Books. At the Effective Time, the stock transfer books of the Company shall be closed and no transfer of Company Shares shall thereafter be made. If, after the Effective Time, Certificates are presented to the Surviving Company, they shall be canceled and exchanged as provided in this Article 2. ARTICLE 3 REPRESENTATIONS AND WARRANTIES 3.1 Representations and Warranties of the Company.

(b) No Subsidiaries. The Company has no subsidiaries, and does not own, directly or indirectly, any capital stock, equity interest or other ownership interest in any corporation, partnership, association, joint venture, limited liability company or other entity.

There are not as of the date of this Agreement and there will not be at the Effective Time any shareholder agreements, voting trusts or other agreements or understandings to which the Company is a party or by which it is bound relating to the voting of any shares of the capital stock of the Company. True and correct copies of all agreements, instruments and other governing documents relating to the Company's Stock Plans have been furnished to Parent. (d) Authority; Non-contravention.

Upon the terms and subject to the conditions set forth in this Agreement, except to the extent otherwise required by United States regulatory considerations and otherwise provided in this Section 5.3, each of the parties agrees to use commercially reasonable efforts to take, or cause to be taken, all actions, and to do, or cause to be done, and to assist and cooperate with the other parties in doing, all things necessary, proper or advisable to consummate and make effective, in the most expeditious manner practicable, the Merger, and the other transactions contemplated by this Agreement, including (i) the obtaining of all necessary actions or nonactions, waivers, consents and approvals from Governmental Entities and the making of all necessary registrations and filings (including filings with Governmental Entities, if any) and the taking of all reasonable steps as may be necessary to obtain an approval or waiver from, or to avoid an action or proceeding by, any Governmental Entity, (ii) the obtaining of all necessary consents, approvals or waivers from third parties, (iii) the defending of any lawsuits or other legal proceedings, whether judicial or administrative, challenging this Agreement or the consummation of the transactions contemplated hereby, including seeking to have any stay or temporary restraining order entered by any court or other Governmental Entity vacated or reversed and (iv) the execution and delivery of any additional instruments necessary to consummate the transactions contemplated by this Agreement; provided, however, that neither of the parties shall be under any obligation to take any action to the extent that the Board of Directors of such party shall conclude in good faith, after consultation with and based upon the written advice of their respective outside legal counsel (which advice in each case need not constitute an opinion), that such action would cause a breach of that Board of Directors' fiduciary obligations under applicable law. In connection with and without limiting the foregoing, each of the Company and Parent and its respective Board of Directors shall (i) take all action necessary to ensure that no state takeover statute or similar statute or regulation is or becomes applicable to the Merger, (ii) if any state takeover statute or similar statute or regulation becomes applicable to the Merger, take all action necessary to ensure that the Merger may be consummated as promptly as practicable on the terms contemplated by this Agreement and otherwise to minimize the effect of such statute or regulation on the Merger and (iii) cooperate with each other in the arrangements for refinancing any indebtedness of, or obtaining any necessary new financing for, the Company and the Surviving Company. (b) Notification. The Company shall give prompt notice to Parent, and Parent or Sub shall give prompt notice to the Company, of (i) any representation or warranty made by it contained in this Agreement becoming untrue or inaccurate in any respect or (ii) the failure by it to comply with or satisfy in any material respect any covenant, condition or agreement to be complied with or satisfied by it under this Agreement; provided, however, that no such notification shall affect the representations or warranties or covenants or agreements of the parties or the conditions to the obligations of the parties hereunder. (c) (i) Each of the parties hereto shall file a premerger notification and report form under the HSR Act with respect to the Merger as promptly as reasonably possible following execution and delivery of this Agreement. Each of the parties agrees to use commercially reasonable efforts to promptly respond to any request for additional information pursuant to Section (e)(1) of the HSR Act. (ii) The Company will furnish to Fulbright & Jaworski L.L.P., counsel to Parent and Sub, copies of all correspondence, filings or communications (or memoranda setting forth the substance thereof (collectively, "Company Regulatory Documents")) between the Company, or any of its respective representatives, on the one hand, and any Governmental Entity, or members of the staff of such agency or authority, on the other hand, with respect to this Agreement or the Merger; provided, however, that (A) with respect to documents and other materials filed by or on behalf of the A-29 Company with the Antitrust Division of the United States Department of Justice, the United States Federal Trade Commission, or any state attorneys general that are available for review by Parent and Sub, copies will not be required to be provided to Fulbright & Jaworski L.L.P. and (B) with respect to any Company Regulatory Documents (1) that contain any information which, in the reasonable judgment of Haynes and Boone, LLP, should not be furnished to Parent or Sub because of antitrust considerations or (2) relating to a request for additional information pursuant to Section (e)(1) of the HSR Act, the obligation of the Company to furnish any such Company Regulatory Documents to Fulbright & Jaworski L.L.P. shall be satisfied by the delivery of such Company Regulatory Documents on a confidential basis to Fulbright & Jaworski L.L.P. pursuant to a confidentiality agreement in form and substance reasonably satisfactory to Parent. Except as otherwise required by United States regulatory considerations, Parent and Sub will furnish to Haynes and Boone, LLP, counsel to the Company, copies of all correspondence, filings or communications (or memoranda setting forth the substance thereof (collectively, "Parent Regulatory Documents")) between Parent, Sub or any of their respective representatives, on the one hand, and any Governmental Entity, or member of the staff of such agency or authority, on the other hand, with respect to this Agreement or the Merger; provided, however, that (A) with respect to documents and other materials filed by or on behalf of Parent or Sub with the Antitrust Division of the United States Department of Justice, the United States Federal Trade Commission, or any state attorneys general that are available for review by the Company, copies will not be required to be provided to Haynes and Boone, LLP, and (B) with respect to any Parent Regulatory Documents (1) that contain information which, in the reasonable judgment of Fulbright & Jaworski L.L.P., should not be furnished to the Company because of antitrust considerations or (2) relating to a request for additional information pursuant to Section (e)(1) of the HSR Act, the obligation of Parent and Sub to furnish any such Parent Regulatory Documents to Haynes and Boone, LLP shall be satisfied by the delivery of such Parent Regulatory Documents on a confidential basis to Haynes and Boone, LLP pursuant to a confidentiality agreement in form and substance reasonably satisfactory to the Company. (iii) At the election of Parent, the Company and Parent shall use reasonable efforts to defend all litigation under the federal or state antitrust laws of the United States which if adversely determined would, in the reasonable opinion of Parent (based on the advice of outside counsel), be likely to result in the failure of the condition set forth in Section 6.1(c) not being satisfied, and to appeal any order, judgment or decree, which if not reversed, would result in the failure of such condition. Notwithstanding the foregoing, nothing contained in this Agreement shall be construed so as to require Parent, Sub or the Company, or any of their respective subsidiaries or affiliates, to sell, license, dispose of, or hold separate, or to operate in any specified manner, any assets or businesses of Parent, Sub, the Company or the Surviving Company (or to require Parent, Sub, the Company or any of their respective subsidiaries or affiliates to agree to any of the foregoing). The obligations of each party under Section 5.3(a) to use commercially reasonable efforts with respect to antitrust matters shall be limited to compliance with the reporting provisions of the HSR Act and with its obligations under this Section 5.3(c). 5.4 Indemnification. (a) From and after the Effective Time, Parent and the Surviving Company shall, indemnify, defend and hold harmless each person who is now, or has been at any time prior to the date hereof or who becomes prior to the Effective Time, an officer or director of the Company or an officer, director or employee of the Company who acts as a fiduciary under any Company Benefit Plans (but, with respect to such persons, only to the extent, if any, indemnified by the Company as of the date hereof) (the "Indemnified Parties") against all losses, claims, damages, costs, expenses (including attorneys' fees), liabilities or judgments or amounts that are paid in settlement with the approval of the indemnifying party (which approval shall not be unreasonably withheld) of or in connection with any threatened or actual claim, action, suit, proceeding or investigation based in whole or in part on or arising in whole or in part out of the fact that such person is or was a director, officer or such employee of the Company whether pertaining to any matter existing or occurring at or prior to the Effective Time and whether asserted or A-30 claimed prior to, or at or after, the Effective Time (including arising out of or relating to the Merger, the consummation of the transactions contemplated herein, and any action taken in connection therewith). Parent and Surviving Company shall advance promptly reasonable litigation expenses incurred by such Indemnified Parties in connection with investigating, preparing and defending any action arising out of such acts or omissions; provided the Indemnified Parties provide the Surviving Company with the written affirmation and written understanding provided in Section 2.02-1.K. of the TBCA. Any Indemnified Party wishing to claim indemnification under this Section 5.4, upon learning of any such claim, action, suit, proceeding or investigation, promptly shall notify the Company (or after the Effective Time, Parent and the Surviving Company), but the failure so to notify shall not relieve a party from any liability that it may have under this Section 5.4, except to the extent such failure materially prejudices such party. Parent or the Surviving Company shall have the right to assume the defense thereof. If Parent or the Surviving Company does not assume the defense, the Indemnified Parties as a group may retain only one law firm to represent them with respect to each such matter unless there is, under applicable standards of professional conduct, a conflict between the positions of any two or more Indemnified Parties. The Indemnified Party shall cooperate in the defense of any such matter. Parent shall not be liable for any settlement effected without Parent's prior written consent. (b) Parent shall use commercially reasonable efforts to purchase and maintain in effect for the benefit of the Indemnified Parties for a period of six years after the Effective Time, directors' and officers' liability insurance of at least the same coverage and amounts containing terms and conditions that are no less advantageous in any material respect to the Indemnified Parties than that maintained by the Company as of the date of this Merger Agreement with respect to matters arising before the Effective Time, provided that Parent shall not be required to pay an annual premium for such insurance in excess of two times the last annual premium paid by the Company prior to the date hereof (which the Company represents and warrants to have been $137,500 in the aggregate), but in such case shall purchase as much coverage as possible for such amount. (c) All rights to indemnification for acts or omissions occurring prior to the Effective Time now existing in favor of the Indemnified Parties as provided in the Company Charter Documents and in any indemnification agreements to which they are parties shall survive the Merger, and the Surviving Company shall continue such indemnification rights for acts or omissions prior to the Effective Time in full force and effect in accordance with their terms and Parent shall be financially responsible therefor. (d) If the Surviving Company or any of its successors or assigns (i) consolidates with or merges into any other person and shall not be the continuing or Surviving Company or entity of such consolidation or merger or (ii) transfers all or substantially all of its properties and assets to any person, then and in each such case, proper provisions shall be made, and Parent shall cause them to be so made, so that the successors and assigns of the Surviving Company, which, in the reasonable opinion of the Surviving Company, shall be financially responsible persons or entities, assume the obligations set forth in this Section 5.4. (e) The provisions of this Section 5.4 are intended to be for the benefit of, and shall be enforceable by, the parties hereto and each Indemnified Party, his or her heirs and representatives. 5.5 Letter of the Company's Accountants. The Company shall use commercially reasonable efforts to cause to be delivered to Parent and Sub a letter of KPMG LLP, the Company's independent public accountants, dated a date within two business days before the date on which the Registration Statement shall become effective and addressed to Parent and Sub and customary in scope and substance for letters delivered by independent public accountants in connection with registration statements similar to the Registration Statement. 5.6 Report of Independent Petroleum Engineers. The Company shall use commercially reasonable efforts to (a) include in the S-4 a report of Joe C. Neal & Associates, independent petroleum engineers, customary in scope and substance for reports of independent petroleum engineers, regarding the Company's oil and gas properties and (b) cause such independent engineers to be named as experts in, and provide the necessary consent to be included as an exhibit to, the S-4. A-31 5.7 Letter of Parent's Accountants. Parent shall use commercially reasonable efforts to cause to be delivered to the Company a letter of PricewaterhouseCoopers LLP, Parent's independent public accountants, dated a date within two business days before the date on which the Registration Statement shall become effective and addressed to the Company and customary in scope and substance for letters delivered by independent public accountants in connection with registration statements similar to the Registration Statement. 5.8 Fees and Expenses. Except as provided in ARTICLE 8, all fees and expenses incurred in connection with the Merger, this Agreement and the transactions contemplated hereby shall be paid by the party incurring such fees or expenses, whether or not the Merger is consummated; provided, however, that all fees and expenses incurred in connection with the filings and related matters under the HSR Act shall be borne equally by Parent and the Company. 5.9 Company Stock Options. After approval of the Merger Agreement by the shareholders of the Company but before consummation of the Merger, the Company shall have cancelled or otherwise terminated all outstanding options to purchase Company Shares granted pursuant to the Company's Stock Plans, including such options as have not yet vested, by paying to the holders of such options in consideration of the cancellation or termination thereof an amount in cash for each Company Share subject to the option equal to the difference between $20.20 and the exercise price per Company Share under the option. The Company shall withhold from such payment and pay over to the appropriate taxing authorities all amounts the Company is required to withhold under federal and, if applicable, state tax laws. As soon as practicable after the date hereof, the Board of Directors of the Company and the Committee of the Board of Directors of the Company administering the Company's Stock Plans shall take all action necessary to accomplish the foregoing. 5.10 Public Announcements. Parent and Sub, on the one hand, and the Company, on the other hand, will consult with each other before issuing any press release or otherwise making any public statements with respect to the transactions contemplated by this Agreement and shall not issue any such press release or make any such public statement prior to such consultation, except that each party may respond to questions from shareholders, respond to inquiries from financial analysts and media representatives in a manner consistent with its past practice and make such disclosure as may be required by applicable law or by obligations pursuant to any listing agreement with the Nasdaq National Market without prior consultation to the extent such consultation is not reasonably practicable. The parties agree that the initial press release or releases to be issued in connection with the execution of this Agreement shall be mutually agreed upon prior to the issuance thereof. 5.11 Agreement to Defend. In the event any claim, action, suit, investigation or other proceeding by any governmental body or other person or other legal administrative proceeding is commenced that questions the validity or legality of the transactions contemplated hereby or seeks damages in connection therewith, the parties hereto agree to cooperate and use their reasonable efforts to defend against and respond thereto. 5.12 Nasdaq National Market. Parent shall use its reasonable best efforts to list on the Nasdaq National Market, upon official notice of issuance, the shares of Parent Common Stock to be issued in connection with the Merger. 5.13 Employee Benefit Plans. For purposes of eligibility to participate in and vesting in benefits under each Parent employee benefit plan provided to the officers and employees of the Company, individuals who are officers and employees of the Company at the Effective Time who continue as employees of Parent or Sub, will be immediately eligible to participate in any qualified plan maintained and sponsored by Parent and will be credited with vesting service for their years of service with the Company. Parent will take such actions as are necessary so that each employee of the Company who continues as an employee of Parent or Sub shall not be subject to preexisting condition exclusions or waiting periods for welfare benefit plan coverages under any Parent employee benefit plan. Subject to temporarily retaining one or more of the Company Benefit Plans to more efficiently transition the Company's employees to Parent benefit plans, Parent shall provide, or shall cause Sub to provide, A-32 compensation and employee benefits to each employee of the Company who continues as an employee of Parent or Sub after the Effective Time which are comparable to the compensation and employee benefits provided to all similarly-situated employees of Parent or Sub. 5.14 Agreements of Others.

The failure of any party to this Agreement to assert any of its rights under this Agreement or otherwise shall not constitute a waiver of such rights. ARTICLE 8 SPECIAL PROVISIONS AS TO CERTAIN MATTERS 8.1 Takeover Defenses of the Company. The Company shall take such action with respect to any anti-takeover provisions in the Company Charter Documents or afforded it by statute to the extent necessary to consummate the Merger on the terms set forth in this Agreement. A-36 8.2 No Solicitation. (a) The Company shall not, and shall not authorize or permit any officer, director or employee of, or any investment banker, attorney or other advisor, agent or representative of, the Company ("Company Representatives") to, and on becoming aware of will take all reasonable actions to stop such person from continuing to, directly or indirectly, (i) solicit, initiate or encourage or otherwise intentionally facilitate (including by way of furnishing information) the making of any Acquisition Proposal (as defined below), (ii) enter into any agreement (other than confidentiality and standstill agreements in accordance with the immediately following proviso) with respect to any Acquisition Proposal, or (iii) participate in any discussions or negotiations regarding, or furnish to any person any information with respect to, or take any other action to facilitate any inquiries or the making of any proposal that constitutes, or may reasonably be expected to lead to, any Acquisition Proposal; provided, however, that in the case of this clause (iii), to the extent required by the fiduciary obligations of the Board of Directors of the Company, determined in good faith by the members thereof, after consultation with outside legal counsel, the Company may at any time prior to Company Shareholder Approval (the "Applicable Period"), but not thereafter if the Merger is approved thereby, and subject to the Company providing written notice to Parent of its decision to take such action in response and only in response to an unsolicited written request therefor received without any initiation, encouragement, discussion or negotiation by the Company or any Company Representative and other than in contravention of this Section 8.2(a)), (A) furnish information to any person or "group" (within the meaning of Section 13(d)(3) of the Exchange Act) pursuant to a confidentiality agreement on substantially the same terms as provided in Section 5.2(b) hereof and otherwise enter into discussions and negotiations with such person or group as to any superior proposal (as defined in Section 8.2(c)) such person or group has made and (B) in the event that the Board of Directors is unable to determine whether such unsolicited written request is a superior proposal, make inquiry of such person or group of such information as would enable the Board of Directors to determine whether or not such request constitutes a superior proposal. Without limiting the foregoing, it is understood that any violation of the restrictions set forth in the preceding sentence by the Company or any Company Representative, whether or not such person is purporting to act on behalf of the Company or otherwise, shall be deemed to be a material breach of this Agreement by the Company. The Company immediately shall cease and shall cause to be terminated any existing solicitation, initiation, encouragement, activity, discussion or negotiation with any parties conducted prior to the date hereof by the Company or any Company Representatives with respect to any Acquisition Proposal existing on the date hereof. The Company promptly will notify Parent of the pendency of any negotiations respecting, or the receipt of, any Acquisition Proposal. For purposes of this Agreement, "Acquisition Proposal" means (i) any proposal, other than a proposal by Parent or any of its affiliates, for a merger or other business combination involving the Company, (ii) any proposal or offer, other than a proposal or offer by Parent or any of its affiliates, to acquire from the Company or any of its affiliates in any manner, directly or indirectly, an equity interest in the Company, any voting securities of the Company or a material amount of the assets of the Company, or (iii) any proposal or offer, other than a proposal or offer by Parent or any of its affiliates, to acquire from the shareholders of the Company by tender offer, exchange offer or otherwise more than 20% of the outstanding Company Shares. (b) Neither the Board of Directors of the Company nor any committee thereof shall, except in connection with the termination of this Agreement pursuant to Sections 7.1(a), 7.1(b), 7.1(c) or 7.1(e), (i) withdraw or modify, or propose to withdraw or modify, in a manner adverse to Parent or Sub, the approval or recommendation by the Board of Directors of the Company or any such committee of this Agreement or the Merger or take any action having such effect or (ii) approve or recommend, or propose to approve or recommend, any Acquisition Proposal. Notwithstanding the foregoing, in the event the Board of Directors of the Company receives an Acquisition Proposal that, in the exercise of its fiduciary obligations (as determined in good faith by a majority of the disinterested members thereof after consultation with outside legal counsel), it determines to be a superior proposal, the Board of Directors may withdraw or modify its approval or recommendation of this Agreement or the Merger and may (subject to the following sentence) terminate this Agreement, in each case at any time after midnight on the third business day following Parent's receipt of written notice (a "Notice of Superior Proposal") A-37 advising Parent that the Board of Directors has received an Acquisition Proposal which it has determined to be a superior proposal, specifying the material terms and conditions of such superior proposal (including the proposed financing for such proposal and a copy of any documents conveying such proposal) and identifying the party making such superior proposal. Parent shall have the right, prior to the expiration of the third business day following its receipt of a Notice of Superior Proposal to agree to amend the terms of this Agreement such that they are no less favorable than the terms of such superior proposal.

A-45 EXHIBIT C Ladies and Gentlemen: I have been advised that as of the date hereof I may be deemed to be an "affiliate" of TMBR/Sharp Drilling, Inc., a Texas corporation (the "Company"), as the term "affiliate" is defined for purposes of paragraphs (c) and (d) of Rule 145 of the Rules and Regulations (the "Rules and Regulations") of the Securities and Exchange Commission (the "Commission") under the Securities Act of 1933, as amended (together with the rules and regulations promulgated thereunder, the "Securities Act"). Pursuant to the terms of the Agreement and Plan of Merger, dated as of May 26, 2003 (the "Merger Agreement"), by and among the Company, Patterson-UTI Energy, Inc., a Delaware corporation ("Parent"), and Patterson-UTI Acquisition, LLC, a Texas limited liability company and a wholly owned subsidiary of Jones ("Sub"), the Company will be merged with and into Sub, in consideration of cash and shares of common stock, par value $.01 per share, of Parent ("Parent Common Stock"), with Sub as the surviving company (the "Merger"). I represent, warrant, and covenant to Parent and Sub that in the event I receive any Parent Common Stock as a result of the Merger: A. I shall not make any sale, transfer or other disposition of any Parent Common Stock acquired by me in the Merger in violation of the Securities Act. B. I have carefully read this letter and the Merger Agreement and discussed their requirements and other applicable limitations upon my ability to sell, transfer, or otherwise dispose of Parent Common Stock, to the extent I felt necessary, with my counsel or counsel for Parent and Sub. C. I have been advised that the issuance of Parent Common Stock to me pursuant to the Merger has been or will be registered with the Commission under the Securities Act on a Registration Statement on Form S-4. I have also been advised, however, that, because at the time the Merger will be submitted for a vote of the shareholders of the Company, I may be deemed to be an affiliate of the Company, the distribution by me of any Parent Common Stock acquired by me in the Merger will not be registered under the Securities Act and that I may not sell, transfer, or otherwise dispose of any Parent Common Stock acquired by me in the Merger unless (i) such sale, transfer, or other disposition has been registered under the Securities Act, (ii) such sale, transfer, or other disposition is made in conformity with the volume and other limitations of Rule 145 promulgated by the Commission under the Securities Act, or (iii) in the opinion of counsel reasonably acceptable to Parent such sale, transfer, or other disposition is otherwise exempt from registration under the Securities Act. D. I understand that Parent is under no obligation to register under the Securities Act the sale, transfer, or other disposition by me or on my behalf of any Parent Common Stock acquired by me in the Merger or to take any other action necessary in order to make an exemption from such registration available. E. I also understand that stop transfer instructions will be given to Parent's transfer agent with respect to Parent Common Stock and that there will be placed on the certificates for any Parent Common Stock acquired by me in the Merger, or any substitutions therefore, a legend stating in substance: "The shares represented by this certificate were issued in a transaction to which Rule 145 promulgated under the Securities Act of 1933 applies. The shares represented by this certificate may only be transferred in accordance with the terms of an agreement dated as of , 2003, between the registered holder hereof and the issuer of this certificate, a copy of which agreement will be mailed to the holder hereof without charge within five days after receipt of written request therefore." A-46 F. I also understand that unless the transfer by me of my Parent Common Stock has been registered under the Securities Act or is a sale made in conformity with the provisions of Rule 145, Parent reserves the right to put the following legend on the certificates issued to my transferee: "The shares represented by this certificate have not been registered under the Securities Act of 1933 and were acquired from a person who received such shares in a transaction to which Rule 145 promulgated under the Securities Act of 1933 applies. The shares may not be sold, pledged, or otherwise transferred except in accordance with an exemption from the registration requirements of the Securities Act of 1933." It is understood and agreed that the legends set forth in paragraph E and F above shall be removed by the delivery of substitute certificates without such legend if the undersigned shall have delivered to Parent a copy of a letter from the staff of the Commission, or an opinion of counsel in form and substance reasonably satisfactory to Parent, to the effect that such legend is not required for purposes of the Securities Act. I understand that (a) Parent will supply me with any information necessary to enable me to make routine sales of any Parent Common Stock acquired by me in the Merger as may be permitted, by and in accordance with, the provisions of Rule 144 under the Securities Act or any similar rule of the Commission hereafter applicable, and (b) Parent will comply with all requirements of the Securities Exchange Act of 1934 and the rules and regulations promulgated thereunder, (the "Exchange Act") with respect to the filing by Parent of annual, periodic and other reports on a timely basis in a manner sufficient to allow sales of any such Parent Common Stock by me during the three year period following the Effective Time (as defined in the Merger Agreement) if such sales are otherwise permitted by law or regulation. Upon my written request, Parent shall furnish me with a written statement representing that it has complied with the reporting requirements enumerated in Rule 144(c)(1), or if Parent is not then subject to Section 13 or 15(d) of the Exchange Act, that it has made publicly available the information concerning Parent required by Rule 144(c)(2).

By -------------------------------------- Name: -------------------------------- Title: --------------------------------- A-48 ANNEX B -- ENERGY CAPITAL SOLUTIONS, LLC FAIRNESS OPINION [ENERGY CAPITAL SOLUTIONS, LLC LETTERHEAD] May 26, 2003 Board of Directors TMBR/Sharp Drilling, Inc. 4607 West Industrial Blvd. Midland, Texas 79703 Members of the Board: PATTERSON-UTI Energy, Inc., a Delaware corporation ("Parent"), Patterson-UTI Acquisition, L.L.C., a Texas limited liability company and a wholly owned subsidiary of Parent ("Sub"), and TMBR/Sharp Drilling, Inc., a Texas corporation (the "Company"), propose to enter into an agreement and plan of merger (the "Agreement") whereby the Company shall merge with and into Sub (the "Merger") and pursuant to which each issued and outstanding share of common stock, $0.10 par value per share of the Company (the "Company Shares"), not owned directly or indirectly by Parent or the Company, will be converted into the right to receive (a) $9.09/share in cash and (b) 0.312166 of a share of common stock, $0.01 par vale per share, of Parent (the "Parent Common Stock"), together the ("Merger Consideration"). You have requested our opinion as to whether the Merger Consideration to be received by the holders of Company Shares (other than Parent and the Company) in the Merger, is fair from a financial point of view to such holders. In arriving at our opinion, we have, among other things: 1. reviewed certain publicly available business and financial information relating to the Company, including (i) its Annual Reports on Form 10-K and related audited financial statements for the fiscal years ended March 31, 2000, March 31, 2001 and March 31, 2002; 2. reviewed a draft dated May 2, 2003 of the Company's unaudited financial statements for the twelve-month period ended March 31, 2003; 3. reviewed certain publicly available business and financial information relating to Parent, including its Annual Reports on Form 10-K and related audited financial statements for the fiscal years ended December 31, 2000, December 31, 2001 and December 31, 2002 and its unaudited financial statements on Form 10-Q for the fiscal quarters ended March 31, 2002 and March 31, 2003; 4. reviewed certain estimates of the Company's oil and gas reserves, including estimates of proved, probable and possible reserves prepared by Joe C. Neal & Associates as of April 1, 2003; 5. analyzed certain historical and projected financial and operating data of the Company; 6. reviewed certain estimates of the Company's yard inventory and other equipment related to the drilling business as prepared by the management of the Company; 7. reviewed certain research reports relating to the historical and projected financial and operating data of Parent prepared by third-parties; 8. discussed the current operations and prospects of the Company and Parent with the management and staff of the Company and Parent, respectively; 9. reviewed the historical market prices and trading history of the Company Shares and the Parent Common Stock; 10. compared recent stock market capitalization indicators for the Company with recent stock market capitalization indicators for certain other publicly-traded independent energy and land drilling companies; B-1 11. compared the financial terms of the Merger with the financial terms of other transactions that we deemed to be relevant; 12. participated in certain discussions among representatives of the Company and Parent and their respective legal and other financial advisors; 13. reviewed a draft dated May 25, 2003 of the Agreement; and 14. reviewed such other financial studies and analyses and performed such other investigations and considered such other matters as we have deemed necessary or appropriate. In connection with our opinion, we have assumed and relied upon, without assuming any responsibility for, or independently verifying, the accuracy and completeness of any information supplied or otherwise made available to us by the Company and Parent. We have further relied upon the assurances of representatives of the management of the Company and Parent that they are unaware of any facts that would make the information provided to us incomplete or misleading in any material respect. With respect to projected financial and operating data, we have assumed that they have been reasonably prepared on bases reflecting the best currently available estimates and judgments of the management of the Company relating to the future financial and operational performance of the Company. With respect to the estimates of oil and gas reserves, we have assumed that they have been reasonably prepared on bases reflecting the best currently available estimates and judgments of the management and staff of the Company (and its engineering consultants) relating to the oil and gas properties of the Company. We have not made an independent evaluation or appraisal of the assets or liabilities of either the Company or Parent, nor, except for the estimates of oil and gas reserves and estimates of drilling equipment and yard inventory referred to above, have we been furnished with any such evaluations or appraisals. In addition, we have not assumed any obligation to conduct, nor have we conducted, any physical inspection of the properties or facilities of either the Company or Parent. In developing our opinion, we have relied upon the Company as to certain legal, tax, and accounting aspects of the transaction contemplated by the Agreement. Consistent with the Agreement, we have assumed that the Merger will be treated as tax-free for federal income tax purposes. We have assumed that the Agreement executed and delivered by the parties will contain identical financial and economic terms and otherwise be substantially similar to the draft Agreement reviewed by us. We have further assumed that the Merger will be consummated on the terms and conditions contemplated in the Agreement. We have not been asked to consider, and this opinion does not address, the prices at which the Parent Common Stock or the Company Shares will actually trade following the announcement or consummation of the Merger. Our opinion is rendered on the basis of conditions in the securities markets and drilling and oil and gas markets as they exist and can be evaluated on the date hereof and the conditions and prospects, financial and otherwise, of the Company as they have been represented to us as of the date hereof or as they were reflected in the materials and discussions described above. Our opinion relates solely to the fairness from a financial point of view of the Merger Consideration to be received by the holders of the Company Shares in the Merger. This opinion is for the use and benefit of the Board of Directors of the Company. This opinion does not address the merits of the underlying decision by the Company to engage in the Merger and does not constitute a recommendation to any holder of Company Shares as to how such holder should vote on the Merger. As you are aware, we are acting as financial advisor to the Company and will receive a fee from the Company for our services, a substantial portion of which is contingent upon the consummation of the Merger. In addition, the Company has agreed to indemnify us for certain liabilities arising out of our engagement. B-2 Based upon and subject to the foregoing, it is our opinion that, as of the date hereof, the Merger Consideration to be received by the holders of the Company Shares (other than Parent and the Company) in the Merger, is fair from a financial point of view to such holders.

C-1 ART. 5.12. PROCEDURE FOR DISSENT BY SHAREHOLDERS AS TO SAID CORPORATE ACTIONS A. Any shareholder of any domestic corporation who has the right to dissent from any of the corporate actions referred to in Article 5.11 of this Act may exercise that right to dissent only by complying with the following procedures: (1)(a) With respect to proposed corporate action that is submitted to a vote of shareholders at a meeting, the shareholder shall file with the corporation, prior to the meeting, a written objection to the action, setting out that the shareholder's right to dissent will be exercised if the action is effective and giving the shareholder's address, to which notice thereof shall be delivered or mailed in that event. If the action is effected and the shareholder shall not have voted in favor of the action, the corporation, in the case of action other than a merger, or the surviving or new corporation (foreign or domestic) or other entity that is liable to discharge the shareholder's right of dissent, in the case of a merger, shall, within ten (10) days after the action is effected, deliver or mail to the shareholder written notice that the action has been effected, and the shareholder may, within ten (10) days from the delivery or mailing of the notice, make written demand on the existing, surviving, or new corporation (foreign or domestic) or other entity, as the case may be, for payment of the fair value of the shareholder's shares. The fair value of the shares shall be the value thereof as of the day immediately preceding the meeting, excluding any appreciation or depreciation in anticipation of the proposed action. The demand shall state the number and class of the shares owned by the shareholder and the fair value of the shares as estimated by the shareholder. Any shareholder failing to make demand within the ten (10) day period shall be bound by the action. (b) With respect to proposed corporate action that is approved pursuant to Section A of Article 9.10 of this Act, the corporation, in the case of action other than a merger, and the surviving or new corporation (foreign or domestic) or other entity that is liable to discharge the shareholder's right of dissent, in the case of a merger, shall, within ten (10) days after the date the action is effected, mail to each shareholder of record as of the effective date of the action notice of the fact and date of the action and that the shareholder may exercise the shareholder's right to dissent from the action. The notice shall be accompanied by a copy of this Article and any articles or documents filed by the corporation with the Secretary of State to effect the action. If the shareholder shall not have consented to the taking of the action, the shareholder may, within twenty (20) days after the mailing of the notice, make written demand on the existing, surviving, or new corporation (foreign or domestic) or other entity, as the case may be, for payment of the fair value of the shareholder's shares. The fair value of the shares shall be the value thereof as of the date the written consent authorizing the action was delivered to the corporation pursuant to Section A of Article 9.10 of this Act, excluding any appreciation or depreciation in anticipation of the action. The demand shall state the number and class of shares owned by the dissenting shareholder and the fair value of the shares as estimated by the shareholder. Any shareholder failing to make demand within the twenty (20) day period shall be bound by the action. (2) Within twenty (20) days after receipt by the existing, surviving, or new corporation (foreign or domestic) or other entity, as the case may be, of a demand for payment made by a dissenting shareholder in accordance with Subsection (1) of this Section, the corporation (foreign or domestic) or other entity shall deliver or mail to the shareholder a written notice that shall either set out that the corporation (foreign or domestic) or other entity accepts the amount claimed in the demand and agrees to pay that amount within ninety (90) days after the date on which the action was effected, and, in the case of shares represented by certificates, upon the surrender of the certificates duly endorsed, or shall contain an estimate by the corporation (foreign or domestic) or other entity of the fair value of the shares, together with an offer to pay the amount of that estimate within ninety (90) days after the date on which the action was effected, upon receipt of notice within sixty (60) days after that date from the shareholder that the shareholder agrees to accept that amount and, in the case of shares represented by certificates, upon the surrender of the certificates duly endorsed. (3) If, within sixty (60) days after the date on which the corporate action was effected, the value of the shares is agreed upon between the shareholder and the existing, surviving, or new corporation (foreign or domestic) or other entity, as the case may be, payment for the shares shall be made within ninety C-2 (90) days after the date on which the action was effected and, in the case of shares represented by certificates, upon surrender of the certificates duly endorsed. Upon payment of the agreed value, the shareholder shall cease to have any interest in the shares or in the corporation. B. If, within the period of sixty (60) days after the date on which the corporate action was effected, the shareholder and the existing, surviving, or new corporation (foreign or domestic) or other entity, as the case may be, do not so agree, then the shareholder or the corporation (foreign or domestic) or other entity may, within sixty (60) days after the expiration of the sixty (60) day period, file a petition in any court of competent jurisdiction in the county in which the principal office of the domestic corporation is located, asking for a finding and determination of the fair value of the shareholder's shares. Upon the filing of any such petition by the shareholder, service of a copy thereof shall be made upon the corporation (foreign or domestic) or other entity, which shall, within ten (10) days after service, file in the office of the clerk of the court in which the petition was filed a list containing the names and addresses of all shareholders of the domestic corporation who have demanded payment for their shares and with whom agreements as to the value of their shares have not been reached by the corporation (foreign or domestic) or other entity. If the petition shall be filed by the corporation (foreign or domestic) or other entity, the petition shall be accompanied by such a list. The clerk of the court shall give notice of the time and place fixed for the hearing of the petition by registered mail to the corporation (foreign or domestic) or other entity and to the shareholders named on the list at the addresses therein stated. The forms of the notices by mail shall be approved by the court. All shareholders thus notified and the corporation (foreign or domestic) or other entity shall thereafter be bound by the final judgment of the court. C. After the hearing of the petition, the court shall determine the shareholders who have complied with the provisions of this Article and have become entitled to the valuation of and payment for their shares, and shall appoint one or more qualified appraisers to determine that value. The appraisers shall have power to examine any of the books and records of the corporation the shares of which they are charged with the duty of valuing, and they shall make a determination of the fair value of the shares upon such investigation as to them may seem proper. The appraisers shall also afford a reasonable opportunity to the parties interested to submit to them pertinent evidence as to the value of the shares. The appraisers shall also have such power and authority as may be conferred on Masters in Chancery by the Rules of Civil Procedure or by the order of their appointment. D. The appraisers shall determine the fair value of the shares of the shareholders adjudged by the court to be entitled to payment for their shares and shall file their report of that value in the office of the clerk of the court. Notice of the filing of the report shall be given by the clerk to the parties in interest. The report shall be subject to exceptions to be heard before the court both upon the law and the facts. The court shall by its judgment determine the fair value of the shares of the shareholders entitled to payment for their shares and shall direct the payment of that value by the existing, surviving, or new corporation (foreign or domestic) or other entity, together with interest thereon, beginning 91 days after the date on which the applicable corporate action from which the shareholder elected to dissent was effected to the date of such judgment, to the shareholders entitled to payment. The judgment shall be payable to the holders of uncertificated shares immediately but to the holders of shares represented by certificates only upon, and simultaneously with, the surrender to the existing, surviving, or new corporation (foreign or domestic) or other entity, as the case may be, of duly endorsed certificates for those shares. Upon payment of the judgment, the dissenting shareholders shall cease to have any interest in those shares or in the corporation. The court shall allow the appraisers a reasonable fee as court costs, and all court costs shall be allotted between the parties in the manner that the court determines to be fair and equitable. E. Shares acquired by the existing, surviving, or new corporation (foreign or domestic) or other entity, as the case may be, pursuant to the payment of the agreed value of the shares or pursuant to payment of the judgment entered for the value of the shares, as in this Article provided, shall, in the case of a merger, be treated as provided in the plan of merger and, in all other cases, may be held and disposed of by the corporation as in the case of other treasury shares. C-3 F. The provisions of this Article shall not apply to a merger if, on the date of the filing of the articles of merger, the surviving corporation is the owner of all the outstanding shares of the other corporations, domestic or foreign, that are parties to the merger. G. In the absence of fraud in the transaction, the remedy provided by this Article to a shareholder objecting to any corporate action referred to in Article 5.11 of this Act is the exclusive remedy for the recovery of the value of his shares or money damages to the shareholder with respect to the action. If the existing, surviving, or new corporation (foreign or domestic) or other entity, as the case may be, complies with the requirements of this Article, any shareholder who fails to comply with the requirements of this Article shall not be entitled to bring suit for the recovery of the value of his shares or money damages to the shareholder with respect to the action. ART. 5.13. PROVISIONS AFFECTING REMEDIES OF DISSENTING SHAREHOLDERS A. Any shareholder who has demanded payment for his shares in accordance with either Article 5.12 or 5.16 of this Act shall not thereafter be entitled to vote or exercise any other rights of a shareholder except the right to receive payment for his shares pursuant to the provisions of those articles and the right to maintain an appropriate action to obtain relief on the ground that the corporate action would be or was fraudulent, and the respective shares for which payment has been demanded shall not thereafter be considered outstanding for the purposes of any subsequent vote of shareholders. B. Upon receiving a demand for payment from any dissenting shareholder, the corporation shall make an appropriate notation thereof in its shareholder records. Within twenty (20) days after demanding payment for his shares in accordance with either Article 5.12 or 5.16 of this Act, each holder of certificates representing shares so demanding payment shall submit such certificates to the corporation for notation thereon that such demand has been made. The failure of holders of certificated shares to do so shall, at the option of the corporation, terminate such shareholder's rights under Articles 5.12 and 5.16 of this Act unless a court of competent jurisdiction for good and sufficient cause shown shall otherwise direct. If uncertificated shares for which payment has been demanded or shares represented by a certificate on which notation has been so made shall be transferred, any new certificate issued therefor shall bear similar notation together with the name of the original dissenting holder of such shares and a transferee of such shares shall acquire by such transfer no rights in the corporation other than those which the original dissenting shareholder had after making demand for payment of the fair value thereof. C. Any shareholder who has demanded payment for his shares in accordance with either Article 5.12 or 5.16 of this Act may withdraw such demand at any time before payment for his shares or before any petition has been filed pursuant to Article 5.12 or 5.16 of this Act asking for a finding and determination of the fair value of such shares, but no such demand may be withdrawn after such payment has been made or, unless the corporation shall consent thereto, after any such petition has been filed. If, however, such demand shall be withdrawn as hereinbefore provided, or if pursuant to Section B of this Article the corporation shall terminate the shareholder's rights under Article 5.12 or 5.16 of this Act, as the case may be, or if no petition asking for a finding and determination of fair value of such shares by a court shall have been filed within the time provided in Article 5.12 or 5.16 of this Act, as the case may be, or if after the hearing of a petition filed pursuant to Article 5.12 or 5.16, the court shall determine that such shareholder is not entitled to the relief provided by those articles, then, in any such case, such shareholder and all persons claiming under him shall be conclusively presumed to have approved and ratified the corporate action from which he dissented and shall be bound thereby, the right of such shareholder to be paid the fair value of his shares shall cease, and his status as a shareholder shall be restored without prejudice to any corporate proceedings which may have been taken during the interim, and such shareholder shall be entitled to receive any dividends or other distributions made to shareholders in the interim.

All capitalized terms used but not defined herein have the meanings ascribed to them in the Agreement and Plan of Merger, dated as of May 26, 2003, among Patterson, Acquisition Sub and the Company (the"MERGER AGREEMENT"). In connection with this opinion, we have examined and relied upon (i) the Merger Agreement, (ii) the Proxy Statement/Prospectus of Patterson and the Company (the "PROXY STATEMENT/PROSPECTUS") included as part of the Registration Statement on Form S-4 filed with the Securities and Exchange Commission (the"COMMISSION") under the Securities Act of 1933, as amended, and the Securities Exchange Act of 1934, as amended (the "REGISTRATION STATEMENT"), (iii) the representation letters delivered by Patterson and the Company to us, and (iv) such other documents as we have deemed necessary or appropriate in order to enable us to render the opinion below (all documents described in this sentence are collectively referred to as the "DOCUMENTS").

ITEM 20. INDEMNIFICATION OF DIRECTORS AND OFFICERS Section 145 of the DGCL allows a corporation to indemnify directors, officers, employees and agents for costs and expenses incurred by or in connection with an action, suit or proceeding brought by reason of their position as a director, officer, employee or agent. The person indemnified must have acted in good faith and in a manner he reasonably believed to be in or not opposed to the best interests of the corporation. The DGCL provides that a corporation may advance payment of expenses under certain circumstances. The DGCL further provides that the indemnification and advancement of expenses provisions of the DGCL will not be deemed exclusive of any other rights of indemnification or advancement of expenses to which directors, officers, employees and agents may be entitled under bylaw, agreement, vote of stockholders or disinterested directors or otherwise, both as to action in such person's official capacity and as to action in another capacity while holding such office. In addition to the general indemnification section, Delaware law provides further protection for directors under Section 102(b)(7) of the DGCL. This section allows a Delaware corporation to include in its certificate of incorporation a provision that eliminates or limits the personal liability of a director to the corporation or its stockholders for monetary damages for breaches of the director's fiduciary duty of care, provided that any such provision does not (in the words of the statute) do any of the following: [E]liminate or limit the liability of a director (i) for any breach of the director's duty of loyalty to the corporation or its stockholders, (ii) for acts or omissions not in good faith or which involve intentional misconduct or a knowing violation of law, (iii) under sec.174 of this Title [dealing with willful or negligent violation of the statutory provision concerning dividends and stock purchases and redemptions], or (iv) for any transaction from which the director derived an improper personal benefit. No such provision shall eliminate or limit the liability of a director for any act or omission occurring prior to the date when such provision becomes effective. . . The DGCL further empowers the board of directors to make other indemnification as authorized under the certificate of incorporation, bylaws or any corporate resolution or agreement so long as the indemnification is consistent with the DGCL. Patterson-UTI's Restated Certificate of Incorporation provides that, to the fullest extent permitted by the DGCL, a director of Patterson-UTI will not be liable to Patterson-UTI or its stockholders for monetary damages for breach of fiduciary duty as a director. Patterson-UTI's Amended and Restated Bylaws provide that, to the maximum extent and in the manner permitted by the DGCL, Patterson-UTI shall indemnify its directors, officers, employees and agents against expenses (including attorneys' fees), judgments, fines, settlements and other amounts actually and reasonably incurred in connection with any proceeding arising by reason of the fact that such person is or was an agent of Patterson-UTI, provided, however, that Patterson-UTI may modify the extent of such indemnification by individual contracts with its directors and officers and, provided, further, that Patterson-UTI shall not be required to indemnify any director or officer in connection with any proceeding (or part thereof) initiated by such person unless (i) such indemnification is expressly required to be made by law, (ii) the proceeding was authorized in advance by the board of directors of Patterson-UTI, (iii) such indemnification is provided by Patterson- UTI, in its sole discretion, pursuant to the powers vested in Patterson-UTI under the DGCL or (iv) such indemnification is required to be made pursuant to an individual contract. Patterson-UTI's Amended and Restated Bylaws also provide that Patterson-UTI may advance the payment of expenses, upon receipt of an undertaking by or on behalf of such person to repay such amounts if it should be determined ultimately that such person is not entitled to be indemnified under the bylaws or otherwise, and that the II-1 indemnification and advancement of expense provisions of the bylaws are nonexclusive. Patterson-UTI maintains director and officer liability insurance covering director and officer indemnification. Patterson-UTI has an Indemnity Agreement with each of its directors and executive officers. The standard for indemnification under the Indemnity Agreement is substantially the same as under Patterson-UTI's Amended and Restated Bylaws. The Indemnity Agreement, however, provides for the creation of a trust account in the event of a "change in control" (as defined in the Indemnity Agreement), funded in an amount sufficient to reasonably satisfy any and all expenses incurred by a director or executive officer in connection with investigating, preparing for, participating in, and/or defending any proceeding relating to any Indemnifiable Event (as defined in the Indemnity Agreement). The trustee of such trust account is to be selected by the director or executive officer receiving the indemnity under the Indemnity Agreement. In the Agreement and Plan of Merger between Patterson Energy, Inc. and UTI Energy Corp. dated as of February 4, 2001, pursuant to which UTI Energy Corp. ("UTI") merged with and into Patterson Energy, Inc. ("Patterson"), with Patterson-UTI as the surviving corporation (the "UTI Merger"), Patterson-UTI agreed to indemnify the former officers and directors of UTI from liabilities arising out of actions or omissions in their capacity as such prior to the effective time of the UTI Merger, and advance reasonable litigation expenses incurred in connection with such actions or omissions, to the full extent permitted under UTI's certificate of incorporation and bylaws. Further, for a period of six years after the effective time of the UTI Merger, Patterson-UTI will provide UTI's officers and directors with an insurance and indemnification policy that provides coverage for acts or omissions through the effective time of the UTI Merger; provided that the maximum aggregate amount of premiums that Patterson-UTI will be required to pay to provide and maintain this coverage does not exceed $300,000 per year. The merger agreement provides that, from and after the effective time of the merger, Patterson-UTI will indemnify the present and former officers, directors and employees of TMBR/Sharp who act as a fiduciary under any of TMBR/Sharp's employee benefit plans from liabilities arising out of in whole or in part such person's acts or omissions as a director, officer or employee of TMBR/Sharp. Patterson-UTI will advance such persons the reasonable litigation expenses in connection with investigating, preparing and defending any action arising out of such acts or omissions. In addition, for a period of six years after the effective time of the merger, Patterson-UTI will provide TMBR/Sharp's officers and directors with an insurance and indemnification policy that provides coverage for acts or omissions through the effective time of the merger; provided that the maximum aggregate amount of premiums that Patterson-UTI will be required to pay to provide and maintain this coverage does not exceed $275,000 per year.

(b) The undersigned registrant hereby undertakes as follows: that prior to any public reoffering of the securities registered hereunder through use of a prospectus which is a part of this registration statement, by any person or party who is deemed to be an underwriter within the meaning of Rule 145(c), the issuer undertakes that such reoffering prospectus will contain the information called for by the applicable registration form with respect to reofferings by persons who may be deemed underwriters, in addition to the information called for by the other Items of the applicable form. (c) The undersigned registrant undertakes that every prospectus (i) that is filed pursuant to the paragraph immediately preceding, or (ii) that purports to meet the requirements of section 10(a)(3) of the Securities Act of 1933 and is used in connection with an offering of securities subject to Rule 415, will be filed as a part of an amendment to the registration statement and will not be used until such amendment is effective, and that for purposes of determining any liability under the Securities Act of 1933, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof. The undersigned registrant hereby undertakes to respond to requests for information that is incorporated by reference into the prospectus pursuant to Items 4, 10(b), 11 or 13 of this Form, within one business day of receipt of such request, and to send the incorporated documents by first class mail or II-3 other equally prompt means. This includes information contained in documents filed subsequent to the effective date of the registration statement through the date of responding to the request. The undersigned registrant hereby undertakes to supply by means of a post-effective amendment all information concerning a transaction, and the company being acquired involved therein, that was not the subject of and included in the registration statement when it became effective. Insofar as indemnification for liabilities arising under the Securities Act of 1933 may be permitted to directors, officers and controlling persons of the registrant pursuant to the foregoing provisions, or otherwise, the registrant has been advised that in the opinion of the Securities and Exchange Commission, such indemnification is against public policy as expressed in the Securities Act of 1933 and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the registrant of expenses incurred or paid by a director, officer or controlling person of the registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Securities Act of 1933 and will be governed by the final adjudication of such issue.
