(e)On April 10, 2008, the Board of Directors (the "Board") of Patterson-UTI Energy, Inc. (the "Company") adopted, subject to stockholder approval, an amendment to the Patterson-UTI Energy, Inc. 2005 Long-Term Incentive Plan (the "2005 Plan") that would increase the number of shares of common stock, $0.01 par value per share ("Common Stock"), reserved for issuance under the 2005 Plan by 4,000,000 shares (the "Amendment").  The Amendment was approved by the Company's stockholders on June 5, 2008, at the Company's annual meeting of stockholders (the "Annual Meeting").<br><br>On April 10, 2008, the Board also adopted, subject to stockholder approval of the Amendment, an amendment to the 2005 Plan regarding the determination of the number of shares available for grant at any particular time under the 2005 Plan (the "Share Multiple Amendment").  The Share Multiple Amendment became effective upon the approval of the Amendment by the Company's stockholders at the Annual Meeting.  Accordingly, each share that is subj
ect to awards granted on or after the date of the Annual Meeting other than options and stock appreciation rights ("SARs") will be counted as two (2.0) shares of Common Stock against the number of shares available for grant under the 2005 Plan.  Additionally, each share of Common Stock that is subject to awards granted under the 2005 Plan other than options and SARs that again becomes available for grant under the 2005 Plan will be added back to the number of shares available for grant under the 2005 Plan as two (2.0) shares.<br><br>     A copy of the Amendment and the Share Multiple Amendment are attached as exhibits to this report and are incorporated herein by reference.  The descriptions set forth above do not purport to be complete, and are qualified by reference to the full text of the exhibits to this report and the 2005 Plan, which has been previously filed.
