   THIS WARRANT HAS NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS
          AMENDED, OR THE LAWS OF ANY STATE AND IS NOT TRANSFERRABLE.


                  STOCK PURCHASE WARRANT TO PURCHASE SHARES OF
                        COMMON STOCK OF UTI ENERGY CORP.


         This certifies that, for value received, ____________________________
(the "Holder"), is entitled, subject to the terms and conditions of this
Warrant, at any time or from time to time during the Exercise Period (as
hereinafter defined), to purchase up to ___________ shares (subject to
adjustment pursuant to Section 9 below) of common stock, $.001 par value
("Common Stock"), of UTI Energy Corp., a Delaware corporation (the "Company")
(the shares of Common Stock issuable upon exercise of this Warrant, as adjusted
under Section 9, being referred to herein as the "Warrant Shares").

         1.      FORM OF ELECTION.

                 The form of election to purchase shares of Common Stock (the
"Form of Election") shall be substantially as set forth in Exhibit A attached
hereto.  The price per Warrant Share and the number of Warrant Shares issuable
upon exercise of this Warrant are subject to adjustment upon the occurrence of
certain events, all as hereinafter provided.

         2.      EXERCISE PERIOD; EXERCISE OF WARRANT.

                 2.1      Exercise Period.  Subject to the terms of this
         Warrant, the Holder shall have the right, which may be exercised at
         any time or from time to time during the Exercise Period, to purchase
         from the Company the number of fully paid and nonassessable Warrant
         Shares this Warrant at the time represents the right to purchase, and,
         in the event that this Warrant is exercised in respect of fewer than
         all of the Warrant Shares purchasable on such exercise, a new warrant
         evidencing the remaining Warrant Shares that may be purchased shall be
         promptly signed, issued and delivered by the Company to the Holder
         pursuant to the provisions of this Section 2.  The term "Exercise
         Period" shall mean the period commencing on July 31, 1998, and
         terminating on July 30, 2003.

                 2.2      Exercise of Warrant.  This Warrant may be exercised
         upon surrender to the Company at its principal office (as designated
         in Section 12) of this Warrant, together with the Form of Election
         duly completed and signed, and upon payment to the Company of the
         Warrant Price (as defined in and determined in accordance with the
         provisions of Sections 3 and 9 hereof) for the number of Warrant
         Shares in respect of which this Warrant is then exercised.  Payment of
         the aggregate Warrant Price with respect to the portion of this
         Warrant being exercised shall be made in cash or by certified or
         official bank check, payable to the order of the Company.

                 Subject to Section 6 hereof, upon the surrender of this
         Warrant and payment of the Warrant Price as set forth above, the
         Company shall issue and cause to be delivered to the Holder or, upon
         the written order of





   3


         the Holder, to and in such name or names as the Holder may designate,
         a certificate or certificates for the number of full Warrant Shares so
         purchased upon the exercise of this Warrant.  Such certificate or
         certificates shall be deemed to have been issued and any person so
         designated to be named therein shall be deemed to have become a holder
         of record of such Warrant Shares as of the date of the surrender of
         this Warrant (together with the duly completed and signed Form of
         Election) and payment of the Warrant Price, as aforesaid.

         3.      WARRANT PRICE.

                 The price per share at which each of the Warrant Shares shall
be purchasable upon exercise of this Warrant initially shall be $26.50, which
price shall be subject to adjustment pursuant to Section 9 hereof (such prices
as so adjusted are referred to herein as the "Warrant Price").

         4.      EXCHANGE OF WARRANT.

                 This Warrant may be exchanged at the option of the Holder when
surrendered at the principal office of the Company for another warrant, or
other warrants of different denominations, of like tenor and representing in
the aggregate the right to purchase a like number of Warrant Shares as this
Warrant then entitles the Holder to purchase.  Any Holder desiring to exchange
this Warrant shall make such request in writing delivered to the Company, and
shall surrender this Warrant for exchange.  Thereupon, the Company shall
promptly sign and deliver to the person entitled thereto a new warrant or
warrants, as the case may be, as so requested.

         5.      NO REGISTRATION OF WARRANT.

                 This Warrant has not been registered under the Securities Act
of 1933, as amended (the "Securities Act"), or any applicable state securities
laws.  The Holder represents and agrees that this Warrant has been, and, upon
exercise hereof, any Warrant Shares will be, acquired for investment and not
with a view to distribution or resale.  The Holder further acknowledges and
agrees that this Warrant may not be transferred, and the Warrant Shares, upon
exercise of this Warrant, may not be transferred, without an effective
registration statement therefor under the Securities Act and applicable state
securities laws or an opinion of counsel satisfactory to the Company that
registration is not required thereunder.  Unless registered, any Warrant Shares
shall bear the following legend:

         The securities represented by this certificate have not been
         registered under the Securities Act of 1933 or the laws of any state
         and may not be transferred in the absence of an effective registration
         statement for the securities under the Securities Act of 1933 and
         applicable state laws or an opinion of counsel satisfactory to the
         Company that such registration is not required.

         6.      PAYMENT OF TAXES.

                 The Company will pay when due and payable any and all U.S.
federal and state transfer taxes and charges that may be payable in respect of
the issuance or delivery of this Warrant or of any Warrant Shares upon the
exercise of this Warrant.  The Company shall not, however, be required to (i)
pay any transfer tax that may be payable in respect of any transfer involved in
the issuance or delivery of certificates for Warrant Shares in the name other
than that of the Holder or (ii) issue or deliver any certificates for Warrant
Shares upon the exercise of this Warrant until such tax shall have been paid
(any such tax being payable by the Holder at the time of surrender) or until it
has been established to the Company's satisfaction that no such tax is due.

         7.      MUTILATED OR MISSING WARRANT.

                 In case this Warrant shall be mutilated, lost, stolen or
destroyed, the Company shall execute, issue and deliver in exchange and
substitution for and upon cancellation of the mutilated Warrant, or in lieu of
and substitution for the lost, stolen or destroyed Warrant, a new warrant of
like tenor and representing an equivalent right or interest, but only upon
receipt of evidence satisfactory to the Company of such loss, theft or
destruction of this Warrant and indemnity, if requested, satisfactory to the
Company.  The Holder requesting such a substitute warrant shall also comply
with such other reasonable regulations and pay such other reasonable charges as
the Company may prescribe.

         8.      RESERVATION OF WARRANT SHARES; PURCHASE OF WARRANT BY THE
                 COMPANY.

                 8.1      Reservation of Warrant Shares.  The Company shall at
         all times reserve for issuance from its authorized and unissued shares
         of Common Stock the number of shares of Common Stock needed for
         issuance upon the exercise of this Warrant.  The Company covenants
         that all shares of Common Stock issuable as herein provided shall,
         when so issued, be duly and validly issued, fully paid and
         nonassessable.

                 8.2      Purchase of Warrant by the Company.  The Company
         shall not be prohibited, except as limited by applicable law, any
         other agreement or herein, from offering to purchase, purchasing or
         otherwise acquiring this Warrant from any holder thereof at such
         times, in such manner and for such consideration as the Company and
         such holder may agree to.

                 8.3      Cancellation of Purchased or Acquired Warrant.  In
         the event the Company shall purchase or otherwise acquire this
         Warrant, the same shall thereupon be canceled and retired.

         9.      ADJUSTMENT OF WARRANT PRICE AND NUMBER OF WARRANT SHARES.

                 9.1      Mechanical Adjustments.  The existence of this
         Warrant shall not affect in any way the right or power of the Company
         or its stockholders to make or authorize any or all adjustments,
         recapitalizations, reorganizations or other changes in the Company's
         capital structure or its business, or any merger or consolidation of
         the Company, or any issue of bonds, debentures, preferred or prior
         preference stock ahead of or affecting the Common Stock or the rights
         thereof, or the dissolution or liquidation of the Company, or any sale
         or transfer of all or any part of its assets or business, or any other
         corporate act or proceeding, whether of a similar character or
         otherwise.

                 If the Company shall effect a subdivision (by stock split,
         stock dividend, recapitalization or otherwise) or consolidation (by
         reverse stock split or otherwise) of shares or other capital
         adjustment of, or the payment of a dividend in capital stock or other
         equity securities of the Company on, the Common Stock, or other
         increase or reduction of the number of shares of the Common Stock
         without receiving consideration therefor in money, services or
         property, or the reclassification of the Common Stock, in whole or in
         part, into other equity securities of the Company, then the number,
         class and per share price of Warrant Shares shall be appropriately
         adjusted (or in the case of the issuance of equity securities as a
         dividend on, or in a reclassification of, the Common Stock, this
         Warrant shall extend to such other securities) in such a manner as to
         entitle the Holder to receive, upon exercise of this Warrant, for the
         same aggregate cash compensation, the same total number and class or
         classes of shares (or in the case of a dividend of, or
         reclassification into, other equity securities, such other securities)
         it would have held after such adjustment if the Holder had exercised
         this Warrant in full immediately prior to the event requiring the
         adjustment.  Comparable rights shall accrue





                                      -4-

         in the event of successive subdivisions, consolidations, capital
         adjustments, dividends or reclassifications of the character described
         above.

                 If the Company shall distribute to all holders of shares of
         Common Stock (including any such distribution made to non-dissenting
         stockholders in connection with a consolidation or merger in which the
         Company is the surviving corporation and in which holders of shares of
         Common Stock continue to hold shares of Common Stock after such merger
         or consolidation) evidences of indebtedness or cash or other assets
         (other than cash dividends payable out of consolidated retained
         earnings not in excess of, in any one year period, the greater of (a)
         $.10 per share of Common Stock and (b) two times the aggregate amount
         of dividends per share paid during the preceding calendar year and
         dividends or distributions payable in shares of Common Stock or other
         equity securities of the Company described in the immediately
         preceding paragraph), then in each case the Warrant Price shall be
         adjusted by reducing the Warrant Price in effect immediately prior to
         the record date for the determination of stockholders entitled to
         receive such distribution by the fair market value, as determined in
         good faith by the Board of Directors of the Company (whose
         determination shall be described in a statement filed in the Company's
         corporate records and be available for inspection by the Holder), of
         the portion of the evidence of indebtedness or cash or other assets so
         to be distributed applicable to one share of Common Stock; provided
         that in no event shall the Warrant Price be less than the par value of
         a share of Common Stock.  Such adjustment shall be made whenever any
         such distribution is made and shall become effective on the date of
         the distribution retroactive to the record date for the determination
         of the stockholders entitled to receive such distribution.  Comparable
         adjustments shall be made in the event of successive distributions of
         the character described above.

                 After the Company shall make a tender offer for, or grant to
         all of its holders of shares of Common Stock the right to require the
         Company to acquire from such stockholders, shares of Common Stock, at
         a price in excess of the Current Market Price (a "Put Right"), or the
         Company shall grant to all of its holders of shares of Common Stock
         the right to acquire shares of Common Stock for less than the Warrant
         Price (the "Purchase Right"), then, in the case of a Put Right, the
         Warrant Price shall be adjusted by multiplying the Warrant Price in
         effect immediately prior to the record date for the determination of
         stockholders entitled to receive such Put Right by a fraction, the
         numerator of which shall be the number of shares of Common Stock then
         outstanding minus the number of shares of Common Stock that could be
         purchased at the Current Market Price for the aggregate amount that
         would be paid if all Put Rights are exercised and the denominator of
         which is the number of shares of Common Stock that would be
         outstanding if all Put Rights are exercised; and, in the case of a
         Purchase Right, the Warrant Price shall be adjusted by multiplying the
         Warrant Price in effect immediately prior to the record date for the
         determination of stockholders entitled to receive such Purchase Right
         by a fraction, the numerator of which shall be the number of shares of
         Common Stock then outstanding plus the number of shares of Common
         Stock that could be purchased at the Current Market Price for the
         aggregate amount that would be paid if all Purchase Rights are
         exercised and the denominator of which is the number of shares of
         Common Stock that would be outstanding if all Purchase Rights are
         exercised.  In addition, the number of shares subject to this Warrant
         shall be adjusted by multiplying the number of shares then subject to
         this Warrant by a fraction that is the inverse of the fraction used to
         adjust the Warrant Price.  Notwithstanding the foregoing, if any such
         Put Rights or Purchase Rights shall terminate without being exercised,
         the Warrant Price and number of shares subject to this Warrant shall
         be appropriately readjusted to reflect the Warrant Price and number of
         shares subject to this Warrant that would have been in effect if such
         unexercised Rights had never existed.  Comparable adjustments shall be
         made in the event of successive transactions of the character
         described above.

                 After the merger of one or more corporations with or into the
         Company, after any consolidation of the Company and one or more
         corporations, or after any other corporate transaction described in
         Section 424(a) of the Internal Revenue Code of 1986, as amended, the
         Holder, at no additional cost, shall be entitled to receive, upon any
         exercise of this Warrant, in lieu of the number of shares as to which
         this Warrant may then be so exercised, the number and class of shares
         of stock or other equity securities to which the Holder would have
         been entitled pursuant to the terms of the agreement of merger or
         consolidation or similar document if at the time of such merger,
         consolidation or other transaction the Holder had been a holder of a
         number of shares of Common Stock equal to the number of shares as to
         which this Warrant may then be so exercised, and, if as a result of
         such merger, consolidation or other transaction, the holders of Common
         Stock are not entitled to receive any stock or other equity securities
         pursuant to the terms thereof, the Holder, at no additional cost,
         shall be entitled to receive, upon exercise of this Warrant, such
         other assets and property, including cash, to which the Holder would
         have been entitled if at the time of such merger, consolidation or
         other transaction the Holder had been the holder of the number of
         shares of Common Stock equal to the number of shares as to which this
         Warrant shall then be so exercised.  Comparable rights shall accrue in
         the event of successive mergers or consolidations of the character
         described above.

                 For purposes of this Section 9.1, "Current Market Price" shall
         mean the closing price of a share of Common Stock on the principal
         national securities exchange on which the Common Stock is listed or,
         if the Common Stock is not so listed, the average bid and asked price
         of a share of Common Stock as reported in the NASDAQ System, in each
         case on the trading day immediately preceding the first trading day on
         which, as a result of the establishment of a record date or otherwise,
         the trading price reflects that an acquiror of Common Stock in the
         public market will not participate in or receive the payment of any
         applicable dividend or distribution.

                 Except as hereinbefore expressly provided, (i) the issue by
         the Company of shares of Common Stock of any class, or securities
         convertible into shares of stock of any class, for cash or property,
         or for labor or services, either upon direct sale or upon the exercise
         of rights or warrants to subscribe therefor, or upon conversion of
         shares or obligations of the Company convertible into such shares or
         other securities, shall not affect, and no adjustment by reason
         thereof shall be made with respect to, the number or price of shares
         of Common Stock then subject to this Warrant and (ii) no adjustment in
         respect of any dividends shall be made during the term of this Warrant
         or upon the exercise of this Warrant.

                 9.2      Voluntary Adjustment by the Company.  The Company may
         at its option, at any time during the term of this Warrant, reduce the
         then current Warrant Price to any amount deemed appropriate by the
         Board of Directors of the Company.

                 9.3      Statement on Warrant.  Irrespective of any
         adjustments in the Warrant Price with respect to this Warrant or the
         number or kind of shares purchasable upon the exercise of this
         Warrant, warrants theretofore or thereafter issued may continue to
         express the same price and number and kind of shares as are stated in
         this Warrant.

         10.     FRACTIONAL INTERESTS.

                 The Company shall not be required to issue fractional Warrant
Shares on the exercise of this Warrant and the number of Warrant Shares
issuable upon such exercise shall be rounded down to the nearest whole share.

         11.     NO RIGHTS AS STOCKHOLDERS; NOTICES TO HOLDER.

                 Nothing contained in this Warrant shall be construed as
conferring upon the Holder the right to vote or to receive dividends or to
consent to or receive notice as a stockholder in respect of any meeting of
stockholders for the election of directors of the Company or any other matter,
or any rights whatsoever as a stockholder of the Company.  If, however, at any
time during the Exercise Period:

                          (a)     the Company shall declare any dividend
                 payable in any securities upon shares of Common Stock or make
                 any distribution (other than a cash dividend or a dividend
                 payable in additional shares of Common Stock) to the holders
                 of shares of Common Stock;

                          (b)     the Company shall offer to the holders of
                 shares of Common Stock any additional shares of Common Stock
                 or securities convertible or exchangeable into shares of
                 Common Stock or any right to subscribe to shares of Common
                 Stock or securities convertible or exchangeable into shares of
                 Common Stock; or

                          (c)     a dissolution, liquidation or winding up of
                 the Company (other than in connection with a consolidation,
                 merger or sale of all or substantially all of its property,
                 assets and business as an entirety) shall be proposed;

then in any one or more of such events, the Company shall give notice in
writing of such event to the Holder as provided in Section 12 hereof at least
10 days prior to the date fixed as a record date or the date of closing the
transfer books for the determination of the stockholders entitled to such
dividend, distribution or subscription rights, or for the determination of
stockholders entitled to vote on such proposed dissolution, liquidation or
winding up.  Such notice shall specify such record date or date of the closing
of the transfer books, as the case may be.  Failure to mail such notice or any
defect therein or in the mailing thereof shall not affect the validity of any
action taken in connection with such dividend, distribution or subscription
rights, or proposed dissolution, liquidation or winding up.

         12.     NOTICES.

         All notices, requests, consents and other communications hereunder
shall be in writing and shall be deemed to have been made when delivered or
mailed first class, postage prepaid:
