ITEM 2:  ACQUISITION OR DISPOSITION OF ASSETS

         On September 11, 1997, UTI Energy Corp., a Delaware corporation (the
"Company"), effected the acquisition of J.S.M. & Associates, Inc., a Texas
corporation ("JSM"), through a merger (the "Merger") of J Acquisition Corp., a
wholly owned Texas subsidiary of the Company ("Sub"), with and into JSM.  The
Merger was effected pursuant to an Agreement and Plan of Merger (the "Merger
Agreement"), dated September 11, 1997, between the Company, Sub, JSM, Jim A.
James and James F. Silhan (together with Mr. James, the "Shareholders"). The
Company acquired JSM for 618,748 shares (including 61,874 shares to be issued
following a contractual post-closing adjustment period) of the Company's Common
Stock, $.001 par value (the "Common Stock"), and $2.6 million in cash, subject
to adjustment.  The Purchase Price was determined through arms-length
negotiations between the parties.  The number of shares of Common Stock issuable
in the transaction was determined by dividing $13.4 million by $21.66, the
average closing sales price of the Common Stock over a 30 day trading period
prior to the transaction less $.75 per share (the "Agreed Stock Price"). JSM's
assets included seven drilling rigs, an office and warehouse in Odessa, Texas
and approximately $950,000 in net working capital.  The Company intends to
continue to operate the business of JSM and integrate JSM's operations with the
Company's existing contract drilling operations. Messrs. Jones and Silhan will
also continue with JSM as operating managers of JSM.

         The cash portion of the Purchase Price was funded with $2.6 million 
in borrowings under the Company's existing line of credit (the "Line of Credit")
with Mellon Bank, N.A. ("Mellon").  The borrowings under the Line of Credit bear
interest at the bank's prime rate and are secured by a pledge of certain of the
Company's rigs, accounts receivable and inventory.

         Under the terms of the Merger Agreement, the Company granted to Messrs.
James and Silhan the right to cause the Company to purchase one-half of the
shares of Common Stock issued to them in the transaction at the Agreed Stock
Price (the "Sale Right"). The Sale Right may only be exercised for a period of
30 days beginning December 10, 1997. The Company also granted to Messrs. James
and Silhan demand and piggyback registration rights exercisable beginning
December 10, 1997. The demand registration rights may not be exercised if
Messrs. James and Silhan exercise their Sale Right.
