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.

                                  ARTICLE III

                EFFECT OF THE MERGER ON THE CAPITAL STOCK OF THE
               CONSTITUENT CORPORATIONS; EXCHANGE OF CERTIFICATES

                 3.1      Effect on Capital Stock.  At the Effective Time, by
virtue of the Merger and without any action on the part of the holder of any
shares of common stock, no par value, of JSM ("JSM Common Stock") or capital
stock of UTI Sub:

                 (a)      Capital Stock of Sub.  Each issued and outstanding
         share of the capital stock of UTI Sub shall be converted into and
         become one fully paid and nonassessable share of common stock, no par
         value, of the Surviving Corporation.

                 (b)      Cancellation of Treasury Stock and UTI-Owned Stock.
         Each share of JSM Common Stock and all other shares of capital stock
         of JSM that are owned by JSM as treasury stock or by UTI, UTI Sub or
         any Subsidiary of JSM or UTI shall be canceled and retired and shall
         cease to exist and no stock of UTI or other consideration shall be
         delivered or deliverable in exchange therefor.

                 (c)      Consideration for JSM Common Stock.  Subject to the
         provisions of Section 3.1(d), each share of JSM Common Stock issued
         and outstanding immediately prior to the Effective Time (other than
         shares to be canceled in accordance with Section 3.1(b)) shall be
         converted into the right to receive on the Closing Date a combination
         of (1) cash in the amount of the Estimated Cash Payment divided by the
         Outstanding JSM Shares and (2) a number of shares of UTI Common Stock
         equal to 90% of the UTI Shares divided by the Outstanding JSM Shares
         (the cash and UTI Common Stock issuable pursuant to this Section
         3.1(c) being referred to as the "Merger Consideration").

                 (d)      Conversion and Cancellation of JSM Common Stock.  All
         shares of JSM Common Stock, when so converted as provided in Section
         3.1(c), shall no longer be outstanding and shall automatically be
         canceled and retired and shall cease to exist, and each holder of a
         certificate representing any such shares shall cease to have any
         rights with respect thereto, except the right to receive such holder's
         allocable portion of the Merger Consideration upon the surrender of
         such certificate in accordance with Section 3.2, without interest, and
         the right to receive such holder's allocable portion of the
         Post-Closing Adjustment and Retained Shares in accordance with Section

                 3.2      Exchange of Certificates.

                 (a)      Exchange Procedure.  Upon surrender of a certificate
representing outstanding shares of JSM Common Stock (a "Certificate") for
cancellation to UTI, together with any other documents reasonably required by
UTI, the holder of such Certificate shall be entitled to receive in exchange
therefor the shares of UTI Common Stock and the cash that such holder has the
right to receive pursuant to the provisions of this Section 3.1, and the
Certificate so surrendered shall forthwith be canceled.  Until surrendered as
contemplated by this Section 3.2, each Certificate shall be deemed at any time
after the Effective Time to represent only the right to receive upon such
surrender the cash and shares of UTI Common Stock as contemplated by Section
3.1.

                 (b)      Distributions with Respect to Unexchanged Shares.  No
dividends or other distributions with respect to UTI Common Stock declared or
made after the Effective Time with a record date after the Effective Time shall
be paid to the holder of any unsurrendered Certificate with respect to the
right to receive shares of UTI Common Stock represented thereby and no cash
payment in lieu of fractional shares shall be paid to any such holder pursuant
to Section 3.2(e) until the holder of such Certificate shall surrender such
Certificate. Subject to the effect of applicable laws, following surrender of
any such Certificate, there shall be paid to the holder thereof, without
interest: (i) at the time of such surrender, the amount of any cash payable in
lieu of a fractional share of UTI Common Stock to which such holder is entitled
pursuant to Section 3.2(e) and the amount of dividends or other distributions
with a record date after the Effective Time theretofore paid with respect to
such whole shares of UTI Common Stock; and (ii) at the appropriate payment
date, the amount of dividends or other distributions with a record date after
the Effective Time but prior to surrender and a payment date subsequent to
surrender payable with respect to such whole shares of UTI Common Stock.

                 (c)      No Further Ownership Rights in JSM Common Stock.  All
shares of UTI Common Stock issued or cash paid upon the surrender for exchange
of shares of JSM Common Stock in accordance with the terms hereof shall be
deemed to have been issued, paid or delivered in full satisfaction of all
rights pertaining to such shares of JSM Common Stock, and after the Effective
Time there shall be no further registration of transfers on the stock transfer
books of the Surviving Corporation of the shares of JSM Common Stock that were
outstanding immediately prior to the Effective Time.  If, after the Effective
Time, Certificates are presented to the Surviving Corporation for any reason,
they shall be canceled and exchanged as provided in this Article III.

                 (d)      No Fractional Shares.  No certificates or scrip
representing fractional shares of UTI Common Stock shall be issued upon the
surrender for exchange of Certificates pursuant to this Article III and all
fractional shares shall be rounded to the nearest whole share of UTI Common
Stock.  Except as provided in this Section 3.2(e), no dividend or other
distribution, stock split or interest shall relate to





                                      -10-
<PAGE>   11
any such fractional security, and such fractional interests shall not entitle
the owner thereof to vote or to any rights as a security holder of UTI.

                 (e)      No Liability.  Neither UTI nor JSM shall be liable to
any holder of shares of JSM Common Stock for such shares (or dividends or
distributions with respect thereto) or any cash amounts to the extent such
amount or UTI Common Stock is delivered to a public official pursuant to any
applicable abandoned property, escheat or similar law.  Any amounts remaining
unclaimed by holders of any such shares two years after the Effective Time (or
such earlier date immediately prior to the time at which such amounts would
otherwise escheat to or become property of any governmental entity) shall, to
the extent permitted by applicable law, become the property of UTI free and
clear of any claims or interest of any such holders or their successors,
assigns or personal representatives previously entitled thereto.

                 (f)      Lost Share Certificates.  If a holder shall have lost
or had destroyed such holder's Certificate, such holder may be entitled to
receive the Merger Consideration and other payments provided for hereunder
subject to such holder providing JSM and UTI with a lost certificate affidavit
and indemnification acceptable to UTI.

                 3.3      Shares of Dissenting Shareholders. Each Shareholder
hereby waives any and all rights to dissent or appraisal with respect to the
Merger.

                 3.4      Post-Closing Adjustment.

                 (a)      Within 60 calendar days after the Closing Date, UTI
shall prepare and deliver to the Shareholders a statement reflecting the
Purchase Price and UTI's calculation thereof (the "Final Statement").  UTI
shall provide the Shareholders with access to copies of all work papers and
other relevant documents to verify the entries contained in the Final
Statement.  The Final Statement shall be prepared in accordance with GAAP.  The
Shareholders shall have a period of 15 calendar days after delivery to it of
the Final Statement to review it and make any objections the Shareholders may
have in writing to UTI.  If written objections to the Final Statement are
delivered to UTI within such 15-day period, then UTI and the Shareholders shall
attempt to resolve the matter or matters in dispute.  If no written objections
are made within the time period provided above, UTI shall pay to the
Shareholders as additional consideration for their shares of JSM Common Stock
acquired in the Merger, in the same proportions as the Shareholders received
the Estimated Cash Payment, the amount, if any, by which the Purchase Price
exceeds the Estimated Purchase Price and the Shareholders, in the same
proportions as the Shareholders received the Estimated Cash Payment, shall
severally reimburse UTI the amount, if any, by which the Estimated Purchase
Price exceeds the Purchase Price, in each case within five calendar days after
the end of such 15-day period.  All payments made pursuant to this Section 3.4
shall be paid in immediately available funds by wire transfer to a bank account
or accounts to be designated by the party or parties to receive the payments.
Notwithstanding the foregoing, except for the creation of accounts receivable
from the sale of goods and





                                      -11-
<PAGE>   12
services, no increases in Working Capital shall be considered for adjustments
to the Purchase Price pursuant to this Section 3.4(a) to the extent such items
reflect noncash adjustments to the carrying value of assets or other noncash
transactions.

                 (b)      If disputes with respect to the Final Statement
cannot be resolved by UTI and the Shareholders within 15 calendar days after
the delivery of the objections to the Final Statement, then either party with
notice to the other party may submit the specific matters in dispute to Arthur
Andersen & Co. or such other nationally recognized independent accounting firm
as may be approved by UTI and the Shareholders which firm shall render its
opinion as to such matters.  Based on such opinion, such accounting firm will
then send to UTI and the Shareholders its determination on the specific matters
in dispute, which determination shall be final and binding on the parties
hereto.  Within five calendar days after delivery of such opinion to UTI and
the Shareholders, UTI shall pay to Shareholders as additional consideration for
their shares of JSM Common Stock acquired in the Merger, in the same
proportions as the Shareholders received the Estimated Payment, the amount, if
any, by which the Purchase Price exceeds the Estimated Cash Payment and the
Shareholders, in the same proportions as the Shareholders received the
Estimated Cash Payment, shall severally reimburse UTI the amount, if any, by
which the Estimated Purchase Price exceeds the Purchase Price. The fees and
other costs charged by each party's own independent accounting firm shall be
borne by such party and the fees and other costs charged by Arthur Andersen &
Co. in connection with resolving any dispute pursuant to this Section 3.4(b)
shall be borne by UTI, on the one hand, and the Shareholders, on the other
hand, equally.  All payments made pursuant to this Section 3.4(b) shall be paid
in immediately available funds by wire transfer to a bank account or accounts
to be designated by the party or parties to receive the payments.

                 (c)      For purposes of determining the Purchase Price under
this Section 3.4, the following shall, without duplication, be applied:

                 (i)      inventory and other equipment not reflected on the
         Balance Sheet shall not be included as a current asset of JSM for
         purposes of calculating the Working Capital of JSM as of the Closing
         Date;

                 (ii)     all accrued or unpaid fees of all law firms and
         accountants providing services for JSM, the Shareholders and any
         Affiliates of JSM or the Shareholders shall be included as current
         liabilities for purposes of calculating the Working Capital of JSM as
         of the Closing Date;

                 (iii)    No Excluded Assets shall be included as a current
         asset of JSM for purposes of calculating the Working Capital of JSM as
         of the Closing Date;

                 (iv)     No accounts receivable from, or other amount owed to
         JSM by, any  Shareholder or Affiliate of any Shareholder shall be
         included as





                                      -12-
<PAGE>   13
         a current asset for purposes of calculating the Working Capital of JSM
         as of the Closing Date;

                 (v)      whether or not set forth on Section 4.6 of the
         Disclosure Schedule, any valuable rights of, or material debt owed to,
         JSM that has been waived by JSM shall not be included as a current
         asset for purposes of calculating the Working Capital of JSM as of the
         Closing Date; and

                 (iv)     all Taxes and other amounts payable as a result of
         Share Redemption and other transactions effected by JSM prior to the
         Closing shall be fully accrued as Debt or a current liability for
         purposes of the calculation of Working Capital of JSM as of the
         Closing Date, as the case may be.

                 (d)      The Shareholders shall cause all accounts receivable
and other amounts owed to JSM from related parties to be paid in full prior to
the Closing and all outstanding Debt under Debt Obligations to be repaid in
full prior to the Closing.

                 (e)      To the extent the Shareholders fail to pay any
amounts due UTI pursuant to the adjustment provisions contained in this Section
3.4, UTI may offset such amounts against the Retained Shares based on an agreed
value equal to the Average Sales Price.  If the Shareholders do not owe any
funds pursuant to this Section 3.4 or pay such funds when due, UTI shall
promptly thereafter deliver the Retained Shares to the Shareholders as
additional consideration in the Merger in the same relative proportions as the
UTI Shares under Section 3.1 delivered to the Shareholders at the Closing.

                                   ARTICLE IV
                         REPRESENTATIONS AND WARRANTIES

         The Shareholders jointly and severally represent and warrant to UTI
that:

         Section 4.1      Incorporation; Authority.  JSM is a corporation duly
organized, validly existing and in good standing under the laws of the State of
Texas, and is duly authorized, qualified and licensed under all applicable
Governmental Requirements to carry on its business in the places and in the
manner as now conducted.  Section 4.1 of the Disclosure Schedule sets forth a
complete list of all jurisdictions in which JSM owns or leases properties, has
employees or conducts business, and a complete list of all jurisdictions in
which JSM is qualified as a foreign corporation.  JSM is duly qualified or
licensed to do business and in good standing as a foreign corporation in every
jurisdiction (which jurisdictions are listed in Section 4.1 of the Disclosure
Schedule) in which the conduct of its business or the ownership or leasing of
its assets require it to be so qualified or licensed, except where the failure
to be so qualified or licensed would not have a Material Adverse Effect.  JSM
has the corporate power and authority to carry on its business as it is now
being conducted and to own and operate





                                      -13-
<PAGE>   14
its assets, properties and business.  The copies of the Articles of
Incorporation of JSM and all amendments thereto to date (certified by the
Secretary of the State of Texas) and of the bylaws of JSM as amended to date
(certified by its Secretary), each of which are included in Section 4.1 of the
Disclosure Schedule, are true, complete and correct.

         Section 4.2      Share Capital.  The authorized capital stock of JSM
consists of 5,000 shares of common stock without par value, of which 3,000
shares are issued and 2,000 shares are outstanding and 1,992 shares will be
outstanding following the Share Redemption.  All of such issued and outstanding
shares are validly issued and outstanding, fully paid and nonassessable.  There
are no outstanding subscriptions, options, warrants, calls, commitments,
obligations or agreements relating to any of the authorized or outstanding
capital stock of JSM.  The Shareholders own all of the issued and outstanding
Shares free and clear of all liabilities, liens, encumbrances, pledges, trusts,
voting trusts or stockholders' agreements, equities, charges, options,
conditional sale or title retention agreements, covenants, restrictions,
reservations, commitments, obligations or other burdens or encumbrances of any
nature whatsoever ("Encumbrances").

         Section 4.3      Subsidiaries.  Except for each entity listed on
Section 4.3 of the Disclosure Schedule (such entities hereinafter referred to
as the "Limited Partnerships"), (i) JSM does not, directly or indirectly, own
or control any capital stock, equity interest, or have any proprietary interest
in, any Person, nor does it directly or indirectly control the management of
any Person, nor does it have any obligation to acquire any such interest in the
future, and (ii) JSM has not, since its inception, directly or indirectly owned
or controlled any capital stock, equity interest, or had any proprietary
interest in, any Person, has it directly or indirectly controlled the
management of any Person.  Each of the Limited Partnerships has been dissolved,
and except as disclosed on Section 4.3 of the Disclosure Schedule, none of the
Limited Partnerships had been, prior to such dissolution, in any way funded or
capitalized.  JSM has provided JSM with copies of all correspondence and
documentation relating to the formation, operation and dissolution of the
Limited Partnerships.

         Section 4.4      Financial Statements.  The Shareholders have
delivered to UTI copies of the JSM August 31, 1997, balance sheet (the
"Reference Balance Sheet"), and income statement for the 11-month period ended
on such date (the "Balance Sheet Date"), copies of which are included in
Section 4.4 of the Disclosure Schedule.

         All financial statements of JSM supplied to UTI by the Shareholders,
whether or not included in Section 4.4 of the Disclosure Schedule, are true and
accurate in all material respects, except as disclosed on Section 4.4 of the
Disclosure Schedule; have been prepared in accordance with GAAP applied on a
consistent basis throughout the periods indicated, and present fairly the
financial condition and the results of the operations of JSM as of the dates
and for the periods indicated thereon, except that the interim period
statements do not include footnotes or normal year-end adjustments.  The
Reference Balance Sheet reflects, as of the Balance Sheet Date, all
liabilities, debts and obligations of any nature of JSM, whether accrued,
absolute, contingent or





                                      -14-
<PAGE>   15
otherwise, and whether due, or to become due, including, but not limited to,
liabilities, debts or obligations on account of Taxes, to the extent such items
are required to be reflected on such balance sheet under GAAP consistently
applied.

         Section 4.5      Liabilities, Debts and Obligations.  JSM has no
liabilities, debts or obligations of any nature whatsoever, whether due or to
become due, and whether accrued, absolute, contingent or otherwise, that are
not disclosed on the Reference Balance Sheet or in this Agreement or the
Disclosure Schedule, except for (a) liabilities incurred in the Ordinary Course
of Business subsequent to the Balance Sheet Date and (b) obligations under
contracts and commitments entered into in the Ordinary Course of Business and
not required under GAAP to be reflected on the Reference Balance Sheet
(including required footnotes), which, in both cases, individually or in the
aggregate are not material to the financial condition or operating results of
JSM.  As of the Balance Sheet Date, there did not exist any declared but unpaid
dividend or other distribution or any repurchase or similar obligation with
respect to any capital stock of JSM.

         Section 4.6      Events Since Balance Sheet Date.  Since the Balance
Sheet Date there has not been, except for the Share Redemption or as disclosed
fully and correctly in Section 4.6 of the Disclosure Schedule:

arrangement or any adoption of or entering into of any new bonus,

except for damages, destruction or loss that reasonably would be expected to
occur in the Ordinary Course of Business not exceeding $25,000, individually or
in the aggregate;

                 (o)      to the best of the Shareholders's or JSM's knowledge,
any other occurrences, events or conditions that have had, or can reasonably be
expected to have, individually or in the aggregate, a Material Adverse Effect
on JSM.

         Section 4.7      Directors, Officers and Employees.  The Shareholders
have provided to UTI a true and complete list of the names of and current
annual compensation paid by JSM to each director, officer and employee of JSM.
With respect to each employee of JSM hired after August 15, 1987, JSM maintains
in its files a fully completed Form I-9 pursuant to the Immigration Reform and
Control Act of 1986, and the rules and regulations promulgated thereunder.  To
the best of JSM's and the Shareholders's knowledge, no officer or key employee
of JSM is in violation of any term of any employment contract, patent
disclosure agreement or any other contract or agreement relating to the
relationship of any such employee with JSM, or any other party.  To the best of
JSM's and the Shareholders's knowledge, no employee of JSM has received notice
from a former employer claiming such employee to be in breach of any such
employment contract, patent disclosure agreement or other contract or
agreement.  JSM does not have any collective bargaining agreements covering any
of its employees.  JSM is not aware that any officer or key employee of JSM, or
that any group of those Persons, intends to terminate their employment with
JSM.  The employment of each officer and employee of JSM is terminable at the
will of JSM.

         Section 4.8      Inventories.  The method of valuing such inventories
as of the Balance Sheet Date is consistent with that used in respect of the
beginning and end of each of the two most recent fiscal years of JSM.

         Section 4.9      Taxes and Governmental Returns and Reports.  Except
as set forth in Section 4.9 of the Disclosure Schedule:

                 (a)      all Tax Returns of or relating to any Tax that are
required to be filed on or before the Closing Date for, by, on behalf of or
with respect to JSM or any of its subsidiaries, including, but not limited to,
those relating to the income, business, operations or property of JSM or any of
its subsidiaries and those which include or should include JSM or any of its
subsidiaries (whether on a separate, consolidated, affiliated, combined,
unitary or any other basis), have been or will be timely filed with the
appropriate foreign, federal, provincial, state and local authorities on or
before the Closing Date, and all Taxes shown to be due and payable on such Tax
Returns or related to such Tax Returns have been or will be paid in full on or
before the Closing Date;

                 (b)      all such Tax Returns and the information and data
contained therein have been or will be properly and accurately compiled and
completed, fairly present or will fairly present the information purported to
be shown therein, and reflect or will reflect all liabilities for Taxes for the
periods covered by such Tax Returns;

                 (c)      none of such Tax Returns are under audit or
examination by any foreign, federal, provincial, state or local authority and
there are no agreements,





                                      -17-
<PAGE>   18
waivers or other arrangements providing for an extension of time with respect
to the assessment or collection of any Tax or deficiency of any nature against
JSM or any of its subsidiaries or with respect to any such Tax Return, or any
suits or other actions, proceedings, investigations or claims now pending or
threatened against JSM or any of its subsidiaries with respect to any Tax, or
any matters under discussion with any foreign, federal, state or local
authority relating to any Tax, or any claims for any additional Tax asserted by
any such authority;

                 (d)      all Taxes assessed and due and owing from or against
JSM or any of its subsidiaries on or before the Closing Date (including, but
not limited to, ad valorem Taxes relating to any property of JSM or any of its
subsidiaries) have been or will be timely paid in full on or before the Closing
Date;

                 (e)      all withholding Tax and Tax deposit requirements
imposed on JSM or any of its subsidiaries for any and all periods ending on or
before the Closing Date, or through and including the Closing Date for periods
that have not ended on or before the Closing Date, have been or will be timely
satisfied in full on or before the Closing Date;

                 (f)      the Financial Statements reflect and include adequate
charges, accruals, reserves and provisions for the payment in full of any and
all Taxes payable with respect to any and all periods ending on or before the
respective dates thereof; and

                 (g)      there is no basis known to the Shareholders for any
reassessment of Tax and there have been no special assessments on any assets of
JSM or its subsidiaries.

         Section 4.10       Employee Benefit Plans.

                 (a)        Section 4.10 of the Disclosure Schedule contains a
list and brief description of all "employee pension benefit plans" (as defined
in Section 3(2) of ERISA) (sometimes referred to herein as "Pension Plans"),
"employee welfare benefit plans" (as defined in Section 3(1) of ERISA)
(sometimes referred to herein as "Welfare Plans") and all other Benefit Plans
maintained, or contributed to, by JSM for the benefit of any present or former
officers or employees of JSM.  JSM has delivered to UTI true, complete and
correct copies of (i) each Benefit Plan (or, in the case of any unwritten
Benefit Plans, descriptions thereof), (ii) the most recent three annual reports
on Form 5500 filed with the IRS with respect to each Benefit Plan, (if any such
report was required), (iii) the most recent IRS determination letter and all
rulings or determinations requested subsequent to the date of that letter, (iv)
the most recent actuarial report for each Benefit Plan for which an actuarial
report is required, (v) the most recent summary plan description for each
Benefit Plan for which such summary plan description is required and each
summary of material modifications prepared after the last summary plan
description, (vi) each trust agreement and group annuity contract relating to
any Benefit Plan and (vii) all material correspondence for the last





                                      -18-
<PAGE>   19
three years with the IRS or Department of Labor relating to plan qualification,
filing of required forms, or pending, contemplated or announced plan audits.

                 (b)        Except as set forth in Section 4.10 of the
Disclosure Schedule, all Pension Plans have been the subject of determination
letters from the IRS to the effect that such Pension Plans are qualified and
exempt from Federal income taxes under Section 401(a) and 501(a), respectively,
of the Code and no such determination letter has been revoked nor has
revocation been threatened, nor has any such Pension Plan been amended since
the date of its most recent determination letter or application therefor in any
respect that would adversely affect its qualification or materially increase
its costs.  To the best of JSM's and the Shareholders's knowledge, no event has
occurred which could subject any Pension Plan to disqualification by the
Internal Revenue Service under the Code.  JSM has paid all premiums (including
any applicable interest, charges and penalties for late payment) due the
Pension Benefit Guaranty Corporation ("PBGC") with respect to each Pension Plan
for which premiums are required.  No Pension Plan maintained by JSM has been
terminated under circumstances which would result in liability to the PBGC.

                 (c)        Each Benefit Plan which has been or is sponsored,
participated in or contributed to by JSM: (i) is in compliance in all material
respects with all requirements of ERISA, (ii) has no issue pending (other than
the payment of benefits in the normal course) nor any issue resolved adversely
to JSM which may subject JSM to the payment of any penalty, interest, tax or
other obligation, and (iii) is in compliance with the terms of the Benefit Plan
and the Code.

                 (d)        The execution of this Agreement or the consummation
of the transactions contemplated by this Agreement will not give rise to any,
or trigger any, change of control, or severance benefit or other similar
provision in any Benefit Plan.

                 (e)        JSM does not provide employee post-retirement
medical or health coverage or contribute to or maintain any employee welfare
benefit plan which provides for health benefit coverage following termination
of employment except as is required by Section 4980B(f) of the Code or other
applicable statute, nor has it made any representations, agreements, covenants
or commitments to provide that coverage.

                 (f)        No Pension Plan that JSM maintains, or to which JSM
is obligated to contribute, had, as of the respective annual valuation date for
each such Pension Plan, an "unfunded benefit liability" (as such term is
defined in Section 4001(a)(18) of ERISA).  None of the Pension Plans has an
"accumulated funding deficiency" (as such term is defined in Section 302 of
ERISA or Section 412 of the Code), whether or not waived.  To the best of JSM's
and the Shareholders's knowledge, none of JSM, any officer of JSM or any of the
Benefit Plans which are subject to ERISA, including the Pension Plans, or any
trusts created thereunder, or any trustee or administrator thereof, has engaged
in a "prohibited transaction" (as such term is defined in Section 406, 407 or
408 of ERISA or Section 4975 of the Code) or any other breach of fiduciary
responsibility that could subject JSM or any officer of JSM to





                                      -19-
<PAGE>   20
the tax or penalty on prohibited transactions imposed by such Section 4975 or
to any liability under Section 502(i)(1) of ERISA.  Neither any of such Benefit
Plans nor any of such trusts have been terminated, nor has there been any
"reportable event" (as that term is defined in Section 4043 of ERISA) with
respect to which the 30-day notice requirement has not been waived and neither
JSM nor the Shareholders is aware of any other reportable events with respect
thereto during the last five years.  JSM has never been a party to or
contributed to a "multiemployer pension plan" (as such term is defined in
Section 4001(a)(3) of ERISA).

                 (g)        With respect to any Benefit Plan that is a Welfare
Plan, (i) no such Benefit Plan includes a welfare benefits fund, as such term
is defined in Section 419(e) of the Code, (ii) each such Benefit Plan that is a
group health plan, as such term is defined in Section 5000(b)(1) of the Code,
complies with the applicable requirements of Section 4980B(f) of the Code and
(iii) each such Benefit Plan (including any such Plan covering retirees or
other former employees) may be amended or terminated without material liability
to JSM on or at any time after the Closing.

                 (h)        Neither JSM, the Shareholders, nor any member of a
controlled group or affiliated service group as defined in Section s 414(b),
(c), (m) and (o) of the Code of which JSM or the Shareholders is a member
(collectively, the "Company") has made a complete or partial withdrawal from a
multiemployer plan (as defined in Section 3(37) of ERISA) so as to incur
withdrawal liability as defined in Section 4201 of ERISA which remains unpaid.
The execution of this Agreement or the consummation of the transactions
contemplated by this Agreement will not give rise to, or trigger, any liability
under ERISA to JSM.  JSM, and each Benefit Plan maintained by JSM has complied
with all the requirements of such Benefit Plan, ERISA, and the Code.  JSM shall
be reimbursed by the Shareholders for all liability, taxes, liens, penalties or
other obligations related to any Benefit Plan maintained or contributed to by
any other member of JSM.

         Section 4.11       Contracts and Agreements.  Section 4.11 of the
Disclosure Schedule sets forth a true and complete list of all of the following
contracts, agreements, leases, licenses, plans, arrangements or commitments,
written or oral, to which JSM is a party or by which JSM or any of its assets
or properties is in any way bound or obligated (including all amendments,
supplements and modifications thereto):

that is a turn-key contract), all subcontracts and contracts in respect of the

the like, all contracts and bids covered by such bonds, and all letters of

                                      -21-
<PAGE>   22
                 (p)        all contracts, agreements, arrangements, or legally

                 (s)        all contracts, agreements, arrangements or legally
enforceable commitments that are material to JSM or the operation of any of its
businesses.

All of such contracts, agreements, leases, licenses, plans, arrangements and
commitments and all other such items binding on JSM or its assets not
specifically described above (collectively, the "Contracts") are valid, binding
and in full force and effect in accordance with their terms and conditions and
there is no existing default thereunder or breach thereof by JSM, or, to the
best of the Shareholders's and JSM's knowledge, by any other party to the
Contracts, or any conditions that, with the passage of time or the giving of
notice or both, might constitute such a default by JSM, or, to the best of the
Shareholders's and JSM's knowledge, by any other party to the Contracts, and
the Contracts will not be breached by or give any other party a right of
termination as a result of the transactions contemplated by this Agreement.
All Contracts were entered into in the Ordinary Course of Business of JSM, and,

products, were entered into by JSM with the intention and expectation by JSM of
realizing a profit from the performance of the Contract.  Copies of all of the
documents (or in the case of oral commitments, descriptions of the material
terms thereof) relevant to the Contracts listed on Section 4.11 of the
Disclosure Schedule have been delivered by the Shareholders to UTI and such
copies and descriptions are true and accurate and include all amendments,
supplements or modifications to the Contracts.

         Section 4.12       Effect of Agreement.  The execution and delivery of
this Agreement by JSM and the Shareholders and the consummation of the Merger
and the transactions contemplated hereby will not (i) result in any breach of
any of the terms or conditions of, or constitute a default under, the Articles
of Incorporation or other charter documents or bylaws of JSM or the
Shareholders, or any commitment, mortgage, note, bond, debenture, deed of
trust, contract, agreement, license or other instrument or obligation to which
JSM or the Shareholders is now a party or by which JSM or the Shareholders or
any of their properties or assets may be bound or affected; (ii) result in any
violation of any Governmental Requirement applicable to JSM or the

or has the right to use (pursuant to a valid lease or license disclosed on
Section 4.11 of the Disclosure Schedule) all property, real or personal,
tangible or intangible, (i) reflected on the Reference Balance Sheet (other
than items sold by JSM since the Balance Sheet Date in the Ordinary Course of
Business for which the proceeds from such sales did not exceed $50,000
individually or in the aggregate) or (ii) utilized in or necessary for the
operation of its business.  Section 4.13 of the Disclosure Schedule sets forth
a true and complete list of all such property as of the date hereof (with all
property that is leased or licensed being designated as such).  JSM has good
and marketable title to all the properties, interests in properties, assets and
leasehold estates, real and personal, set forth in Section 4.13 of the
Disclosure Schedule, free and clear of all mortgages, liens, pledges,
conditional sales agreements, charges, easements, covenants, assessments,
restrictions and encumbrances of any nature whatsoever.  All leases of property
under which JSM purports to be a lessee are valid, binding and in full force
and effect.  Except as set forth in Section 4.13 of the Disclosure Schedule,
the structures, equipment and other properties owned or used by JSM are in good
operating condition and repair, normal wear and tear excepted; provided,
however, that no representation is provided with respect to the operational
condition of JSM's rigs.  During the past two years, there has not been any
significant interruption of the business of JSM due to the breakdown or
inadequate maintenance of any of the assets of JSM.  All such structures,
equipment and other properties of JSM and the present use of such items conform
to all Governmental Requirements, and no notice of any violation of any such
Governmental Requirements relating to such assets or their use has been
received by JSM.  JSM has all easements, rights of ingress and egress, and
utilities and services necessary for all operations conducted by it.  Neither
the whole nor any portion of any real property owned or occupied by JSM has
been condemned or otherwise taken by any public authority, nor, to the best of
the Shareholders's and JSM's knowledge, is any such condemnation or taking
threatened or planned.

         Section 4.14       Bank Accounts.  Section 4.14 of the Disclosure
Schedule sets forth a true and complete list of all bank or financial accounts
and safe deposit boxes of JSM and of the credit and debit balances of such bank
and financial accounts as of the most recent practicable date.  Since the date
of the balances set forth on such list, there have been no payments out of or
drafts against any of the accounts included therein other than routine payments
and drafts in the ordinary course of business.  Section 4.14 of the Disclosure
Schedule also lists all persons having signatory authority over or access to
such bank and financial accounts and safe deposit boxes.

         Section 4.15       Suits, Actions and Claims.  Except as set forth in
Section 4.15 of the Disclosure Schedule, (i) there are no suits, actions,
claims, inquiries, investigations or legal, administrative or arbitration
proceedings involving JSM or in which JSM is engaged or that are pending or, to
the best of the Shareholders' and JSM's knowledge, threatened against or
affecting JSM or any of its properties, assets or business, or that





                                      -23-
<PAGE>   24
question the validity or legality of the transactions contemplated hereby, (ii)
no basis or grounds for any such suit, action, claim, inquiry, investigation or

decree of any Governmental Authority against or affecting JSM or any of its
properties, assets or business.  Section 4.15 of the Disclosure Schedule sets
forth all claims, including the status thereof, over the past two years against
JSM with respect to personal injury, negligence or responsibility for damages
or injuries relating to JSM's business and operations or for reservoir damage
or obligation to redrill or work over a well.

         Section 4.16       Insurance Policies.  Section 4.16 of the Disclosure
Schedule contains a list of all insurance policies (specifying the insurer, the
amount of coverage, the type of insurance and the policy number) covering JSM
or its properties, assets, business and personnel.  Such policies afford JSM
coverage in such amounts and against such risks as is customary for companies
engaged in the same type and scope of business as JSM.  There are no special
circumstances with respect to such policies or the business or operations of
JSM that lead to any liability under such insurance policies being avoided by
the insurers issuing such policies or, to the best of the Shareholders's and
JSM's knowledge, the premiums thereunder being increased.  Except as set forth
on Section 4.16 of the Disclosure Schedule, there is no claim outstanding under
any such insurance policy nor to the best of the Shareholders's and JSM's
knowledge are there any circumstances that are likely to give rise to such a
claim.  JSM is not in default with respect to any provision contained in such
insurance policies, nor has it failed to give any notice or present any claim
thereunder in timely fashion. All such policies are in full force and effect,
with all premiums due thereon to date fully paid.

         Section 4.17       Licenses and Permits; Compliance with Governmental
Requirements.  Section 4.17 of the Disclosure Schedule sets forth a true and
complete list of all licenses and permits necessary for the conduct of JSM's
business.  JSM has all such licenses and permits validly issued to it and in
its name, and all such licenses and permits are in full force and effect.  True
and correct copies of all such licenses and permits necessary for the conduct
of business are included in Exhibit 4.17 hereto.  No violations are or have
been recorded in respect of such licenses or permits and no proceeding is
pending or, to the best of the Shareholders's and JSM's knowledge, threatened
seeking the revocation or limitation of any of such licenses or permits.  The
consummation of the transactions contemplated by this Agreement will not
constitute a violation of any such license or permit or impair or adversely
affect in any manner any such license or permit.  JSM has complied with all
Governmental Requirements applicable to its business, and all Governmental
Requirements with respect to the distribution and sale of products and services
by it.

         Section 4.18       Authorization.  Each Shareholder has all requisite
legal right, power, capacity and authority to execute and deliver this
Agreement and to perform fully such Shareholder's obligations hereunder.  This
Agreement has been duly executed by each Shareholder and constitutes the legal,
valid and binding obligation of such Shareholder, enforceable against such
Shareholder in accordance with its terms, except





                                      -24-
<PAGE>   25
as limited by applicable bankruptcy, moratorium, insolvency or other similar
laws affecting generally the rights of creditors or by principles of equity.

         Section 4.19       No Untrue Statements.  The statements,
representations and warranties of the Shareholders set forth in this Agreement
and the Exhibits hereto and in all other documents and information furnished to
UTI and UTI Sub and its representatives in connection herewith do not include
any untrue statement of a material fact or omit to state any material fact
necessary to make the statements, representations and warranties made not
misleading.

         Section 4.20       Records.  The books, records and minutes kept by
JSM with respect to its business and assets have been kept properly in all
material respects in accordance with all Governmental Requirements and contain
records of all matters required to be included therein by any Governmental
Requirement or by generally accepted accounting principles, and such books,
records and minutes are true, accurate and complete in all material respects.

         Section 4.21       No Dissolution or Judgment.  No order has been
entered or petition presented or resolution passed for the dissolution or
winding up of JSM nor has any distress, execution or other process been levied
in respect of JSM or any of its assets nor is there any unfulfilled or
unsatisfied judgment or order outstanding against JSM.

         Section 4.22       Accounts Receivable.  All notes and accounts
receivable of JSM shown on the Reference Balance Sheet or that have arisen
since the Balance Sheet Date ("Accounts Receivable") have arisen in the
Ordinary Course of Business.  All Accounts Receivable either (i) have been
collected or (ii) are collectible on the respective due dates thereof, or, if
no due date is stated with respect thereto, within ninety (90) days of their
creation in the Ordinary Course of Business, in each case in the aggregate
recorded amounts thereof, less the applicable reserves with respect thereto
reflected on the Reference Balance Sheet.  JSM has not factored or discounted
or agreed to factor or discount any Account Receivable.  The values at which
the Accounts Receivable are carried reflect the accounts receivable valuation
policy of JSM which is consistent with JSM's past practice and in accordance
with GAAP, consistently applied.  Section 4.22 of the Disclosure Schedule sets
forth a true, correct and complete list of all Accounts Receivable written off
by JSM, in whole or in part, as uncollectible during the two years preceding
the date hereof.  Section 4.22 of the Disclosure Schedule also sets forth a
true, correct and complete aging of the Accounts Receivable of JSM as of the
most recent practicable date.

         Section 4.23       Environmental Representations and Warranties.

                 (a)        Neither JSM nor any Shareholder has received any
written notice of any investigation or inquiry by any Governmental Authority

nonperformance on or before the Closing Date.

                                   ARTICLE XI
                      OBLIGATIONS OF PARTIES AFTER CLOSING

         Section 11.1       Post-Closing Confidentiality.  After the Closing,
the Shareholders and their Affiliates shall maintain as confidential
information all information in their possession regarding JSM or its business
or assets, and shall not disclose any of such information to any Person except
as may be required to comply with applicable law.

         Section 11.2       Cooperation Regarding Financial Information.

                 (a)        The Shareholders, if requested by UTI, shall
cooperate and assist Ernst & Young LLP or other accounting firm designated by
UTI (the "Accountants") in preparing such audited financial statements of JSM
that UTI may reasonably require in order to permit UTI to timely file a Current
Report Form 8-K with the Securities and Exchange Commission in accordance with
the Securities Exchange Act of 1934, as amended, and the rules and regulations
thereunder in connection with the transactions contemplated hereby and to
comply with any financial statement requirements with respect to JSM applicable
to UTI under the Securities Exchange Act of 1934, as amended, the Securities
Act and the rules and regulations thereunder.  If requested, the Shareholders
shall use reasonable good faith efforts to cause Elms, Faris & Company to
assist the Accountants in delivering such audited financial statements to UTI
within ten business days prior to the date that UTI is required to file such
financial statements with the Securities and Exchange Commission in connection
with such obligations.  The Shareholders shall cause Elms, Faris & Company to
provide UTI with access to such firm's work papers in support of any accounting
or auditing work performed by Elms, Faris & Company in respect of JSM.  The
cost of such audit, including fees relating to assistance provided by Elms,
Faris & Company, shall be borne by UTI.  The Shareholders will cooperate with
and assist UTI in preparing, and, if requested, shall use reasonable efforts to
cause Elms, Faris & Company to cooperate with, and assist the Accountants in
preparing such other audited financial statements for JSM as may be specified
by UTI.

                 (b)        If in connection with any audit of JSM or UTI
requiring historical information regarding the Excluded Assets, the
Shareholders shall provide such information regarding the same as JSM or UTI
may from time to time request.

         Section 11.3       Covenant Not to Compete With the Business.  Each of
the Shareholders agrees that, effective as of the Closing Date, for a period of
five years thereafter in all jurisdictions other than Louisiana, which shall be
applicable for two years only, such Shareholder will not, and will cause each
of his Affiliates to not,





                                      -36-
<PAGE>   37
without the consent of UTI, directly or indirectly, provide contract land
drilling services in the State of Texas, Oklahoma, New Mexico and Louisiana
except for the account of UTI and its Affiliates.  The Shareholders acknowledge
that a remedy at law for any breach or attempted breach of this Section 11.3
will be inadequate and further agree that any breach of this Section 11.3 will
result in irreparable harm to JSM and, accordingly, UTI and JSM shall, in
addition to any other remedy that may be available to any of them, be entitled
to specific performance and injunctive and other equitable relief in case of
any such breach or attempted breach.  The Shareholders acknowledge that this
covenant not to compete is being provided as an inducement to UTI to acquire
the Shares and that this Section 11.3 contains reasonable limitations as to
time, geographical area and scope of activity to be restrained that do not
impose a greater restraint than is necessary to protect the goodwill or other
business interest of UTI and JSM.  Whenever possible, each provision of this
Section 11.3 shall be interpreted in such a manner as to be effective and valid
under applicable law but if any provision of this Section 11.3 shall be
prohibited by or invalid under applicable law, such provision shall be
ineffective to the extent of such prohibition or invalidity, without
invalidating the remaining provisions of this Section 11.3.  If any provision
of this Section 11.3 shall, for any reason, be judged by any court of competent
jurisdiction to be invalid or unenforceable, such judgment shall not affect,
impair or invalidate the remainder of this Section 11.3 but shall be confined
in its operation to the provision of this Section 11.3 directly involved in the
controversy in which such judgment shall have been rendered.  In the event that
the provisions of this Section 11.3 should ever be deemed to exceed the time or
geographic limitations permitted by applicable laws, then such provision shall
be reformed to the maximum time or geographic limitations permitted by
applicable law.

under this Agreement or from any misrepresentation in or omission from any
list, schedule, certificate or other instrument furnished or to be furnished to
the Shareholders pursuant to the terms of this Agreement (excluding in each

indemnify UTI Indemnified Parties pursuant to Section 13.1 above):

         Section 13.3       Indemnification Basket; Effect of Materiality
Qualifiers.

                 (a)        There shall be no indemnification for a

be obligated to the other party for any and all such damages without regard to
the Basket Amount.

                 (b)        For purposes of determining the right of a party to
make a claim for indemnification for a breach of representation or warranty
under Sections 13.1 and 13.2, all representations and warranties that have been
made subject to a materiality or dollar qualification (including any Material
Adverse Effect) shall be deemed to have been made without that qualification,
it being understood and agreed that the thresholds provided for under Section

for purposes of indemnification.

         Section 13.4       Waiver of Contribution.  Any claim for
indemnification made by any UTI Indemnified Party pursuant to Article XIII

UTI will give prompt notice thereof in writing to the party from which
indemnity may be sought, together with a statement of such information
regarding the Indemnity Claim as it shall then have, provided that any delay in
giving or failure to give such notice shall not limit any indemnified party's
rights to indemnity hereunder except to the extent that the indemnifying party
is shown to have been materially prejudiced by such delay or failure.

                                   ARTICLE XV
                          REGISTRATION AND PUT RIGHTS

         Section 15.1       Demand Rights.  On one occasion after 90 days
following the Closing Date (the "Demand Date"), the Shareholders may request (a
"Demand Request"), pursuant to this Section 15.1, that UTI register under the
Securities Act the UTI Shares issued to the Shareholders under this Agreement
pursuant to a non-underwritten offering to be made 90 days following the
Closing Date, having a period of distribution not to exceed 90 days; provided,
however, UTI shall not be obligated to prepare and file any registration
statement pursuant to this Section 15.1, or prepare or file any amendment or
supplement thereto, and may suspend sales under, at any time when UTI
reasonably believes that the filing thereof at the time requested, or the
offering of securities pursuant thereto, would materially and adversely affect
a pending or proposed public offering of securities of UTI, an acquisition,
merger, recapitalization, consolidation, reorganization or similar transaction
relating to UTI or negotiations, discussions or pending proposals with respect
thereto or require premature disclosure of information not otherwise required
to be disclosed to the potential detriment of UTI; provided, however, that such
period of sale or distribution shall resume after any such suspension for a
number of days necessary to keep such registration effective for permitted
sales thereunder for a term of 90 days.  The filing of a registration
statement, or any amendment or supplement thereto, by UTI may not be deferred,
and the sale and distribution of shares may not be suspended, in each case
pursuant to the foregoing provisions, for more than 60 days after the
abandonment or consummation (or the completion of the distribution of
securities in the case of a public offering) of any of the proposals or
transactions described therein or, in any event, for more than 90 days.

         Section 15.2       Piggyback Rights.  If, at any time after 90 days
following the Closing Date, UTI proposes to register under the Securities Act
any shares of UTI Common Stock for sale by it pursuant to an underwritten
public offering of the UTI Common Stock (except with respect to registration
statements filed on Form S-4 or such other forms as shall be prescribed under
the Securities Act for the same purposes as such form), it will at each such
time, prior to the filing of any such registration statement, give written
notice to the Shareholders of its intention so to do, regardless of whether the
Shareholders have previously exercised piggyback registration rights or demand
rights as to any other shares of stock held by it, and, upon the written
request (which must specify the number of shares of UTI Common Stock to
participate in such underwritten offering) of the Shareholders delivered to UTI
within five days of receipt of UTI's notice, UTI will use its best efforts to
cause any UTI Shares as to which registration shall have been so requested to
be included in the shares to be covered by the registration statement proposed
to be filed by UTI.  Nothing contained in this Section 15.2 shall, however,
limit UTI's right to cancel, postpone or withdraw any such proposed
registration for any reason.  Any request by the Shareholders pursuant to this
Section 15.2 to register UTI Shares for sale in the underwriting shall be on
the same terms and conditions as the shares of UTI Common Stock to be
registered and sold through underwriters under such registration; provided,
however, that as a condition





                                      -43-
<PAGE>   44
to such inclusion the Shareholders shall execute an underwriting agreement
acceptable to the underwriters and, if requested, a custody agreement having
such customary terms as the underwriters shall request, including
indemnification, and if the managing underwriter determines and advises in
writing that the inclusion in the underwriting of all UTI Shares proposed to be
included by the Shareholders and any other shares of UTI Common Stock sought to
be registered by any other stockholder of UTI exercising rights comparable to
those of the Shareholders under this Agreement would, in its reasonable and
good faith judgment, interfere with the successful marketing of the securities
proposed to be registered for underwriting by UTI or by any holder of UTI
Common Stock having the right to require UTI to file a registration statement
to register such UTI Common Stock (the "Other Common Stock"), then the number
of UTI Shares and Other Common Stock requested to be included in the
underwriting shall be reduced pro rata among the Shareholders and the holders
of Other Common Stock requesting such registration and inclusion in the
underwriting and may, in the determination of such managing underwriter and
consistent with pro rata reduction, be reduced to zero.

         Section 15.3       Procedure.  If and whenever UTI is required by the
provisions of this Agreement to use its best efforts to effect the registration
of any UTI Shares under the Securities Act, UTI will, subject to the other
provisions of this Section 14:

                 (a)        as expeditiously as reasonably practicable after
demand therefor, prepare and file with the Securities and Exchange Commission
(the "Commission") a registration statement on the appropriate form with
respect to such UTI Shares and seek to cause such registration statement to
become and remain effective;

                 (b)        as expeditiously as reasonably practicable, prepare
and file with the Commission such amendments and supplements to such
registration statement and the prospectus used in connection therewith as may
be necessary to keep such registration statement effective and to comply with
the provisions of the Securities Act with respect to the disposition of such
UTI Shares covered by such registration statement in accordance with the
intended method of distribution set forth in such registration statement;

                 (c)        as expeditiously as reasonably practicable, furnish
to the Shareholders such number of copies of prospectuses and preliminary
prospectuses in conformity with the requirements of the Securities Act, and
such other documents as the Shareholders may reasonably request, in order to
facilitate the public sale or other disposition of such UTI Shares; provided,
however, that the obligation of UTI to deliver copies of prospectuses or
preliminary prospectuses to the Shareholders shall be subject to the receipt by
UTI of reasonable assurances from the Shareholders that it will comply with the
applicable provisions of the Securities Act and of such other securities laws
as may be applicable in connection with any use by it of any prospectuses or
preliminary prospectuses;





                                      -44-
<PAGE>   45
                 (d)        as expeditiously as practicable, use its best
efforts to register or qualify UTI Shares covered by such registration
statement under such other securities laws of such United States jurisdictions
as the Shareholders shall reasonably request (considering the nature and size
of the offering) and do any and all other acts and things which may be
necessary or desirable to enable the Shareholders to consummate the public sale
or other disposition in such jurisdictions of UTI Shares; provided, however,
that UTI shall not be required to qualify to transact business as a foreign
corporation in any jurisdiction in which it would otherwise not be required to
be so qualified or to take any action which would subject it to general service
of process in any jurisdiction in which it is not then so subject;

                 (e)        bear all Registration Expenses (as defined below)
in connection with all registrations hereunder; provided, however, that all
Selling Expenses (as defined below) of UTI Shares and all fees and
disbursements of counsel for the Shareholders in connection with each
registration pursuant to this Article 13 shall be borne by the Shareholders.
Expenses incurred by UTI in complying with this Article 15, including, without
limitation:  (i) all registration and filing fees; (ii) all printing expenses;
(iii) all fees and disbursements of counsel for UTI; (iv) all blue sky fees and
expenses; and (v) all fees and expenses of accountants for UTI are herein
referred to as "Registration Expenses".  All underwriting fees and discounts
and brokerage and selling commissions relating to UTI Shares to be registered
for sale by the Shareholders and fees and expenses of the counsel for the
Shareholders and any underwriter's counsel applicable to the sales by the
Shareholders in connection with any such registration are herein referred to as
"Selling Expenses"; and

                 (f)        keep each registration pursuant to Section 15.1
hereof effective for a period of up to 90 days or such shorter period of time
until the transfer or sale of all UTI Shares so registered has been completed.

         Section 15.4       Indemnification.

                 (a)        In the event of a registration of any UTI Shares
under the Securities Act pursuant to this Article 15, UTI will indemnify and
hold harmless the Shareholders and any other Person, if any, who controls the
Shareholders within the meaning of Section 15 of the Securities Act, against
any losses, claims, damages or liabilities, joint or several, to which the
Shareholders or such controlling Person may become subject under the Securities
Act or otherwise, insofar as such losses, claims, damages or liabilities or
actions in respect thereof arise out of or are based upon any untrue statement
or alleged untrue statement of any material fact contained, on the effective
date thereof, in any registration statement under which such UTI Shares were
registered under the Securities Act, any preliminary prospectus distributed
with the consent of UTI or final prospectus contained therein, or any amendment
thereof or supplement thereto, including all documents incorporated by
reference therein, or arise out of or are based upon the omission or alleged
omission to state therein a material fact required to be stated therein or
necessary to make the statements therein not misleading, and will reimburse the
Shareholders and each such controlling Person for





                                      -45-
<PAGE>   46
any legal or any other expenses reasonably incurred by them in connection with
investigating or defending any such loss, claim, damage, liability or action;
provided, however, that UTI will not be liable in any such case to the extent
that any such loss, claim, damage or liability arises out of or is based upon
an untrue statement or alleged untrue statement or omission or alleged omission
made in such registration statement, such preliminary prospectus, such final
prospectus or such amendment or supplement, including all documents
incorporated by reference therein, in reliance upon and in conformity with
written information furnished to UTI by or on behalf of the Shareholders or a
controlling Person of the Shareholders specifically for use in the preparation
thereof.

                 (b)        In the event of any registration of any UTI Shares
under the Securities Act pursuant to this Agreement, the Shareholders shall
jointly and severally indemnify and hold harmless UTI and each Person, if any,
who controls UTI within the meaning of Section 15 of the Securities Act, each
officer of UTI who signs the registration statement, each director of UTI and
each underwriter (if any) and each Person who controls any underwriter (if any)
within the meaning of Section 15 of the Securities Act, against any and all
such losses, claims, damages, liabilities or actions which UTI or such officer,
director, underwriter (if any) or controlling Person may become subject under
the Securities Act or otherwise, and will reimburse UTI, each such officer,
director, underwriter (if any) and controlling Person for any legal or any
other expenses reasonably incurred by such party in connection with
investigating or defending any such loss, claim, damage, liability or action,
if (a) such loss, claim, damage, liability or action in respect thereof arises
out of or is based upon any untrue statement or alleged untrue statement of any
material fact contained in any such registration statement or any such
prospectus, or any amendment thereof or supplement thereto, or arises out of or
is based upon the omission or alleged omission to state therein a material fact
required to be stated therein or necessary to make the statements therein not
misleading, and any such statement or omission of a material fact was made in
reliance upon and in conformity with written information furnished to UTI by or
on behalf of the Shareholders specifically for use in connection with the
preparation of such registration statement or prospectus or (b) such loss,
claim, damage, liability or action in respect thereof arises out of or is based
upon the Shareholders's failure to deliver any required prospectus or otherwise
comply with applicable laws regarding the same.  In connection with any
transaction contemplated by Section 15.2 hereof, the Shareholders also agree to
indemnify each such underwriter and each Person who controls any such
underwriter within the meaning of Section 15 of the Securities Act as may
reasonably and customarily be requested by the underwriters in connection with
any underwritten offering of such UTI Shares.

                 (c)        Promptly after receipt by any indemnified Person of
notice of any claim or commencement of any action in respect of which indemnity
is to be sought against an indemnifying Person pursuant to this Agreement, such
indemnified Person shall notify the indemnifying Person in writing of such
claim or of the commencement of such action, and, subject to provisions
hereinafter stated, in case any such action shall be brought against an
indemnified Person and such indemnifying Person shall





                                      -46-
<PAGE>   47
have been notified of the same, such indemnifying Person shall be entitled to
participate therein, and, to the extent it shall wish, to assume the defense
thereof, with counsel reasonably satisfactory to such indemnified Person, and
after notice from the indemnifying Person to such indemnified Person of its
election to assume the defense thereof, such indemnifying Person shall not be
liable to such indemnified Person in connection with the defense thereof;
provided, however, if there exists or will exist a conflict of interest which
would make it inappropriate in the reasonable judgment of the indemnified
Person for the same counsel to represent both the indemnified Person and such
indemnifying Person then such indemnified Person shall be entitled to retain
its own counsel at the expense of such indemnifying Person; provided further,
however, the indemnifying Person shall not be required to pay for more than one
separate counsel for all of the indemnified Persons in addition to any local
counsel.

         Section 15.5       Termination.  If Rule 144 or Rule 145 as
promulgated under the Securities Act or any successor or similar rule or
statute shall permit the sale of UTI Shares in compliance with the conditions
thereof and the provisions thereof, the rights of the Shareholders as to
registration provided for in this Agreement as to such UTI Shares shall
terminate immediately.

         Section 15.6       Shareholder Put Right.  So long as the Shareholders
have not made a Demand Request pursuant to Section 15.1, for a period of 30
days following the Demand Date, the Shareholders may on one occasion request
(the "Put Request") that UTI repurchase from the Shareholders up to one-half of
the UTI Shares issued to them pursuant to the Merger at a repurchase price
equal to the Average Sales Price per share of UTI Common Stock.  Such request
shall be made by the Shareholders in writing and shall designate the total
number of UTI Shares requested by the Shareholders to be repurchased and be
accompanied by the certificates representing the UTI Shares to be repurchased
endorsed in blank with a gold medallion signature guarantee.  The UTI Shares to
be repurchased shall be transferred free and clear of all liens and
encumbrances.  UTI shall pay the repurchase price by wire transfer to the
account or accounts designated in the Put Request two business days following
receipt by UTI of the Put Request and all required documents for against
transfer of the applicable UTI Shares to UTI.  The Shareholders and UTI agree
to execute and deliver all agreements, certificates or other documents
reasonably requested by the other party in connection with the Shareholders'
exercise of their rights under this Section 15.6.

                                  ARTICLE XVI
                                 MISCELLANEOUS

         Section 16.1       Binding Agreement.  All the provisions, covenants,
representations, warranties and conditions of this Agreement shall be binding
upon, and inure to the benefit of and be enforceable by, the parties hereto and
their respective successors and assigns.  Prior to the Closing Date, no party
hereto may assign any of its interest herein without the written consent of the
other party (which consent will not be unreasonably withheld), provided that
UTI may assign its rights under this





                                      -47-
<PAGE>   48
Agreement to an Affiliate without any requirement for such consent, but such
assignment shall not release UTI of its obligations under this Agreement if
such obligations are not performed by the assignee.  After the Closing Date,
except for the rights under Article XV, which may not be assigned, the rights
of each party hereto may be assigned by such party without any requirement for
consent from the other party.

parties hereto with respect to the subject matter hereof.

         Section 16.4       Expenses.  Except as otherwise provided herein,

         Section 16.5       Severability.  If any term or other provision of
this Agreement is held invalid, illegal or incapable of being enforced under
any rule or law, all other conditions and provisions of this Agreement shall
nevertheless remain in full force and effect so long as the economic or legal
substance of the transactions contemplated hereby is not affected in a
materially adverse manner with respect to either party.  Upon such
determination that any term or other provision is invalid, illegal or incapable
of being enforced, the parties hereto shall negotiate in good faith to modify
this Agreement so as to effect the original intent of the parties as closely as
possible in an acceptable manner to the end that transactions contemplated
hereby are fulfilled to the extent possible.

         Section 16.6       Waivers.  The failure of any party at any time to
require performance of any provision hereof shall not affect its right later to
require such performance.  No waiver in any one or more instances shall (except
as otherwise stated therein) be deemed to be a further or continuing waiver of
any such condition or breach in other instances or a waiver of any condition or
breach of any other term, covenant, representation or warranty.

         Section 16.7       Counterparts.  This Agreement may be executed in
one or more counterparts, each of which shall be deemed an original but all of
which together shall constitute one and the same instrument.

articles and sections of this Agreement are for convenience only and are not
part of this Agreement.

         Section 16.9       Applicable Law.  This Agreement is governed by and
shall be construed and enforced in accordance with the internal laws of the
State of Texas.

         Section 16.10      Construction of Agreement.  This Agreement
constitutes a negotiated agreement among the parties and the fact that one
party or the other shall have drafted a particular provision or provisions
shall not be material in the construction of any provision.  All Exhibits
referred to in the Agreement are a part of the Agreement.

         Section 16.11      References to Articles, Sections and Exhibits.
Unless the context otherwise requires, all references herein to Articles,
Section s and Exhibits shall be to the Articles, Sections and Exhibits of and
