II-1 5 ITEM 4. DESCRIPTION OF SECURITIES. Not Applicable. ITEM 5. INTEREST OF NAMED EXPERTS AND COUNSEL. The validity of the shares of the Registrant's Common Stock offered hereby are being passed upon for the Registrant by Baker & Hostetler, LLP, counsel to the Registrant. Members of that firm currently own 7,000 shares of the Registrant's Common Stock. ITEM 6. INDEMNIFICATION OF DIRECTORS AND OFFICERS. The Delaware General Corporation Law ("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 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: "eliminate 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 Section 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 of the Registrant to make other indemnification as authorized under the provisions of the restated certificate of incorporation or bylaws, corporate resolution or agreement so long as the indemnification is consistent with the DGCL. The Registrant's restated certificate of incorporation provides that, to the fullest extent permitted by the DGCL, a director of the Registrant will not be liable to the Registrant or its stockholders for monetary damages for breach of fiduciary duty as a director. The Registrant's II-2 6 bylaws provide that to the extent that a director, officer, employee or agent of the Registrant is successful on the merits of defense of a suit or proceeding brought against him by reason of his position within the Registrant, he shall be indemnified against expenses (including attorneys' fees) actually and reasonably incurred in connection with such action. In other circumstances, a director, officer employee or agent of the Registrant may be indemnified against expenses (including attorneys' fees), judgments, fines and amounts paid in settlement actually and reasonably incurred by him in connection with such action, suit or proceeding if he acted in good faith and in a manner he reasonably believed to be in and not opposed to the best interest of the Registrant, and, with respect to a criminal action or proceeding, had no reasonable cause to believe his conduct was unlawful; however, in an action or suit by or in the right of the Registrant to procure a judgment in its favor, such person will not be indemnified if he has been adjudged to be liable to the Registrant unless and only to the extent that the Delaware Court of Chancery or the court in which such action or suit was brought determines upon application that, despite the adjudication of liability but in view of all the circumstances of the case, such person is fairly and reasonably entitled to indemnity for such expenses which the Court of Chancery or such other court deems proper. A determination that indemnification is proper will be made by a majority of the Registrant's disinterested directors, by independent legal counsel or by the stockholders of the Registrant. The Registrant's bylaws also provide that the Registrant may advance the payment of expenses and that the indemnification and advancement of expense provisions of the bylaws are nonexclusive. The Registrant maintains director and officer liability insurance covering director and officer indemnification. In addition, 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 the Registrant as the surviving corporation ("Merger"), the Registrant 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 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 Merger, the Registrant will provide UTI's officers and directors with an insurance and indemnification policy that provides coverage through the effective time of the Merger; provided that the maximum aggregate amount of premiums that the Registrant will be required to pay to provide and maintain this coverage does not exceed $300,000 per year. ITEM 7. EXEMPTION FROM REGISTRATION CLAIMED. Not Applicable. ITEM 8. EXHIBITS. The Exhibits listed in the accompanying Exhibit Index are filed or incorporated by reference as part of this Registration Statement. ITEM 9. UNDERTAKINGS. A. The undersigned Registrant hereby undertakes: II-3 7 (1) To file, during any period in which offers or sales are being made, a post-effective amendment to this registration statement: (i) to include any prospectus required by Section 10(a)(3) of the Securities Act; (ii) to reflect in the prospectus any facts or events arising after the effective date of the registration statement (or the most recent post-effective amendment thereof) which, individually or in the aggregate, represent a fundamental change in the information set forth in the registration statement. Notwithstanding the foregoing, any decrease or increase in volume of securities offered (if the total dollar value of the securities offered would not exceed that which was registered) and any deviation from the low or the high end of the estimated maximum offering range may be reflected in the form of a prospectus filed with the Commission pursuant to Rule 424(b) if, in the aggregate, the changes in volume and price represent no more than a 20% change in the maximum aggregate offering price set forth in the "Calculation of Registration Fee" table in this Registration Statement; and (iii) to include any material information with respect to the plan of distribution not previously disclosed in the registration statement or any material change to such information in the registration statement; provided, however, that clauses (i) and (ii) do not apply if the information required to be included in a post-effective amendment by those clauses is contained in periodic reports filed with or furnished to the Commission by the Registrant pursuant to Section 13 or Section 15(d) of the Securities Exchange Act of 1934, as amended ("Exchange Act") that are incorporated by reference in this Registration Statement; (2) That, for the purpose of determining any liability under the Securities Act, 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; and (3) To remove from registration by means of a post-effective amendment any of the securities being registered that remain unsold at the termination of the offering. B. The undersigned Registrant hereby undertakes that, for purposes of determining any liability under the Securities Act, each filing of the Registrant's annual report pursuant to Section 13(a) or Section 15(d) of the Exchange Act (and, where applicable, each filing of an employee benefit plan's annual report pursuant to Section 15(d) of the Exchange Act) that is incorporated by reference in the registration statement 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. C. Insofar as indemnification for liabilities arising under the Securities Act may be permitted to directors, officers and controlling persons of the Registrant pursuant to the provisions described under Item 6 above or otherwise, the Registrant has been advised that in the opinion of the Commission such indemnification is against public policy as expressed in the Securities Act 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 and will be governed by the final adjudication of such issue. II-4 8 SIGNATURES Pursuant to the requirements of the Securities Act, the Registrant certifies that it has reasonable grounds to believe that it meets all of the requirements for filing on Form S-8 and has duly caused this Post-Effective Amendment No. 1 to the Registration Statement to be signed on its behalf by the undersigned, thereunto duly authorized, in the City of Snyder, State of Texas, on the 24th day of July, 2001.
