                   PATTERSON-UTI ENERGY, INC. AND SUBSIDIARIES
         NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS


1.       BASIS OF CONSOLIDATION AND PRESENTATION

         On May 8, 2001, the merger between Patterson Energy, Inc. and UTI
Energy Corp. ("UTI") was consummated by vote of the stockholders of each of the
companies. The merger was treated as a reorganization within the meaning of
Section 368(a) of the Internal Revenue Code of 1986, as amended, and was
accounted for as a pooling of interests for financial accounting purposes.
Accordingly, historical financial statements as presented herein, have been
restated to provide for the retroactive effect of the merger. As a part of the
merger, the name of Patterson Energy, Inc. was changed to "Patterson-UTI Energy,
Inc." (see Note 2).

         The consolidated financial statements include the accounts of
Patterson-UTI Energy, Inc. ("Patterson-UTI") and its wholly-owned subsidiaries,
(collectively referred to herein as "Patterson-UTI" or the "Company"). All
significant intercompany accounts and transactions have been eliminated.

         The interim condensed consolidated financial statements have been
prepared by management of the Company, without audit, pursuant to the rules and
regulations of the Securities and Exchange Commission. Certain information and
footnote disclosures normally included in financial statements prepared in
accordance with generally accepted accounting principles have been omitted
pursuant to such rules and regulations, although the Company believes the
disclosures included herein are adequate to make the information presented not
misleading. In the opinion of management, all adjustments (consisting of only
normal recurring accruals) considered necessary for presentation of the
information have been included. The unaudited condensed consolidated balance
sheet as of December 31, 2000, as presented herein, was derived from the audited
balance sheets of the Company and UTI, but does not include all disclosures
required by generally accepted accounting principles.

         The U.S. dollar is the functional currency for all of the Company's
operations except for its Canadian operations, which use the Canadian dollar as
functional currency. The effects of exchange rate changes are reflected in
accumulated other comprehensive income, which is a separate component of
stockholders' equity.

         The Company provides a dual presentation of its earnings per share:
Basic Earnings per Share ("Basic EPS") and Diluted Earnings per Share ("Diluted
EPS"). Basic EPS is based on the weighted average number of shares outstanding
during the periods presented. Diluted EPS includes common stock equivalents,
which are dilutive to earnings per share. For the three and nine-month periods
ended September 30, 2001, the dilutive securities were approximately 1.8 million
and 2.9 million, respectively, compared to dilutive securities of approximately
3.6 million and 3.7 million for the three and nine-month periods ended September
30, 2000.

         The results of operations for the three and nine months ended September
30, 2001, are not necessarily indicative of the results to be expected for the
full year.

         Certain reclassifications have been made to the 2000 consolidated
financial statements in order for them to conform with the 2001 presentation.

                   PATTERSON-UTI ENERGY, INC. AND SUBSIDIARIES
    NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS-CONTINUED

2.       RECENT ACQUISITIONS AND UTI MERGER

Acquisitions

         On January 5, 2001, the Company consummated the transactions
contemplated by certain agreements among the Company and Jones Drilling
Corporation, Henderson Welding, Inc., L.E.J. Truck and Crane, Inc., and L.E.
Jones Drilling Company (collectively the "Jones Entities"). The acquired assets
consisted of 21 drilling rigs (of which 14 were marketable when acquired) and
related equipment and approximately $2.3 million of net working capital. The net
purchase price of $33.2 million consisted of 810,070 shares of the Company's
common stock valued at $26.8125 per share and $11.3 million cash plus
approximately $240,000 in transaction costs. The pro forma results of combining
the consolidated results of operations as if the Jones Entities had been
acquired on January 1, 2000, are considered immaterial and have no effect on
earnings per share.

         In January 2001, the Company acquired six drilling rigs, through three
separate transactions, for approximately $15.7 million in cash.

         The above acquisitions were accounted for as purchases and the related
results of operations and cash flows have been included in the condensed
consolidated financial statements since the respective dates of acquisition. No
goodwill was recorded in connection with these acquisitions.

UTI Merger

         On February 4, 2001, Patterson Energy, Inc. entered into an Agreement
and Plan of Merger with UTI providing for the merger of the two entities. On May
8, 2001, the stockholders of each company approved the merger. Each outstanding
share of UTI common stock was converted into one share of Patterson-UTI common
stock and each option or warrant then outstanding representing the right to
receive UTI common stock was converted into the right to purchase Patterson-UTI
common stock on an equivalent basis. A total of 37,782,135 shares of
Patterson-UTI common stock was issued pursuant to the merger and an additional
3,621,079 shares were reserved for issuance under the then outstanding UTI stock
options. Additionally, the stockholders of Patterson-UTI approved an increase in
the Company's authorized shares of common stock from 50 million to 200 million
and a name change to "Patterson-UTI Energy, Inc." following consummation of the
merger.

         The Company incurred $13.1 million in expenses related to the merger.
Such expenses consisted of $5.9 million in merger costs which were primarily
related to professional fees paid to investment banking firms, attorneys,
accountants and commercial printers for their professional services rendered and
$7.2 million in restructuring costs and other related charges incurred as a
result of the following:

         o        severance costs and related expenses of $2.8 million,

         o        closing of duplicate operational facilities of $1.6 million,

         o        costs of $1.0 million incurred for repaying the Company's
                  credit facility (see Note 6),

         o        fees and expenses related to the transfer of licenses and
                  leaseholds, and in some instances the impairment of such
                  leaseholds, the combination or cancellation of various service
                  contracts and the renegotiation of certain insurance policies
                  of $1.8 million.

         The merger was treated as a reorganization within the meaning of
Section 368(a) of the Internal Revenue Code of 1986, as amended, and was
accounted for as a pooling of interests for financial accounting purposes. The
consolidated financial statements give retroactive effect to the merger, which
includes combining the companies' previous historical consolidated financial
statements as of December 31, 2000 and for the three and nine-month periods
ended September 30, 2000. Certain immaterial adjustments were made in those

3.       STOCKHOLDERS' EQUITY

         As a part of the merger with UTI, the Company's stockholders approved
the merger and an amendment to the Company's Charter increasing the number of
authorized shares of the Company's common stock to 200 million (see Note 2).

         On May 7, 2001, warrants to purchase 121,250 shares of UTI's common
stock were exercised. The exercise price ranged from $13.25 to $17.50. The $1.8
million in proceeds resulting from the exercise was used as partial payment of
notes payable owed to the same parties (see Note 6).

         In January 2001, the Company issued 810,070 shares of its common stock
as partial consideration for the acquisition of Jones Drilling Corporation and
its related entities (see Note 2). The common stock was valued at $26.8125 per
share, its fair market value on the date of the announcement of the transaction.

         The adjustments above were made to conform the accounting methods of
Patterson-UTI and UTI to adjust for certain differences between the two
companies' relative methods of accounting for the recognition of revenue under
turnkey drilling contract arrangements. Patterson-UTI applies the completed
contract method to turnkey drilling contracts which requires revenue and costs
associated with drilling the well to be deferred until drilling is complete. UTI
accounted for its turnkey arrangements using the percentage-of-completion method
in which revenue was recognized as costs were incurred relative to the expected
total cost of drilling the well.

6.       NOTES PAYABLE

         On July 30, 2001, the Company paid $12.0 million on its outstanding
debt with CIT Group/Business Credit, Inc., Foothill Capital Corp., Fleet Capital
Corp., and The CIT Group/Equipment Financing, Inc. ("CIT"), and on August 17,
2001, the Company paid the remaining $8.0 million then outstanding, incurring an
additional $355,000 in fees associated with the early repayment.

         During the first six months of 2001, the Company repaid, prior to their
scheduled maturities, $69.2 million under its existing credit facilities and
other term obligations. The Company incurred expenses of $448,000 as a result of
prepayment penalties and $587,000 related to deferred financing costs which were
unamortized at the time the debt was extinguished.

         On June 29, 2001, the Company increased its existing revolving line of
credit with CIT to $100.0 million and extended the term of the facility to June
2005. The revolving line of credit carries a floating interest rate of LIBOR
plus 1.75% to 2.75% based on Patterson-UTI's twelve-month trailing Earnings
Before Income Taxes, Depreciation, Depletion and Amortization ("EBITDA"). The
facility has no significantly restrictive financial or operational covenants
until amounts drawn under the facility exceed $80.0 million.

7.       CONTINGENCIES

         The Company is involved in several claims arising in the ordinary
course of business. Management believes all such claims are covered by insurance
or that such matters will not have a material adverse effect on the Company's
financial statements.

         The Company is self-insured for employee health insurance claims up to
a maximum of $100,000 per employee under medical claims, at which point the
Company is fully insured. The Company is self-insured for workers compensation
up to a maximum of $500,000 per event for workers compensation claims, at which
point the Company is fully insured. Although the Company believes that adequate
reserves have been provided for expected liabilities arising from its
self-insured obligations, management's estimates of these liabilities may change
in the future as circumstances develop.

         The Company's operations are subject to the many hazards inherent in
the onshore drilling industry, such as blowouts, explosions, sour gas, well
fires and spills. These hazards can result in personal injury and loss of life,
severe damage to or destruction of property and equipment, pollution or
environmental damage and suspension of operations. Although the Company
maintains insurance protection as management deems appropriate, such insurance
coverage may not provide sufficient funds to protect the Company from all
liabilities that could result from its operations. Also, claims will be subject
to various retentions and deductibles. While the Company has generally been able
to obtain some degree of contractual indemnification from its customers in most
of its dayrate drilling contracts, no such indemnification is typically
available for footage or turnkey contracts. The indemnity agreements require the
customers to hold the Company harmless in the event of loss of production or
reservoir damage. This contractual indemnification may not be supported by
adequate insurance maintained by the customer.

         The Company's operations routinely involve the handling of various
materials, including hazardous materials. The Company may be exposed to
liability under numerous state and federal environmental laws, rules and
regulations including dealing with hazardous materials. In addition,
environmental laws and regulations including The Comprehensive Environmental
Response, Compensation and Liability Act (also know as the "Superfund Law"), may
impose strict liability whereby the Company could be liable for clean-up costs,
even if the situation resulted from previous conduct of the Company that was
lawful at the time conducted or from improper conduct of or conditions caused by
previous property owners or other persons not associated with the Company.

7.       CONTINGENCIES - (CONTINUED)

The Company maintains insurance coverage against some environmental liabilities,
including pollution caused by sudden and accidental oil spills.

         Management believes it has adequately reserved for these contingencies.
Management believes that the outcome of known and potential claims will not have
a material adverse effect on the Company's operations.


8.       BUSINESS SEGMENTS

         The Company primarily conducts its business through three distinct
operating activities: contract drilling of oil and natural gas wells and
provision of pressure pumping services and drilling and completion fluid
services to operators in the oil and natural gas industry. Separate financial
data for each of the Company's three business segments is provided below.

ITEM 2. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
OF OPERATIONS

         THE FOLLOWING SUMMARY OF LIQUIDITY AND CAPITAL RESOURCES AND RESULTS OF
OPERATIONS IS BASED ON CONSOLIDATED FINANCIAL INFORMATION THAT HAS BEEN RESTATED
TO REFLECT THE MERGER OF UTI INTO PATTERSON-UTI ON MAY 8, 2001, UNDER THE
POOLING OF INTERESTS METHOD OF ACCOUNTING.

LIQUIDITY AND CAPITAL RESOURCES

         As of September 30, 2001, we had working capital of approximately
$123.3 million including cash and cash equivalents of $30.5 million as compared
to working capital of $127.3 million including cash and cash equivalents of
$66.9 million at December 31, 2000. For the nine months ended September 30,
2001, our various sources and uses of cash flow were:

Sources:

         o        $196.8 million derived from operations primarily attributable
                  to the following factors:

                  o        Net income of $145.5 million which was largely
                           attributable to an:

                  o        Increase in average dayrates from $9,121 per day in
                           the fourth quarter of 2000 to $12,033 per day in the
                           third quarter of 2001 and a resulting increase in
                           average daily cash margins from $2,793 per day in the
                           fourth quarter of 2000 to $5,673 per day in the third
                           quarter of 2001,

                  o        Improvement in utilization rates as indicated in
                           "Results of Operations" on page 14, and

                  o        Increase in average operating rigs from 199 in the
                           fourth quarter of 2000 to 225 in the third quarter of
                           2001, primarily due to the addition of 27 drilling
                           rigs in January of 2001 with the purchase of Jones
                           Drilling Corporation and three other affiliated
                           entities and three other transactions.

         o        $5.1 million from the exercise of stock options and warrants,

         o        $668 thousand from the sale of certain property and
                  equipment and

         o        $9.8 million in loan proceeds from the Company's revolving
                  line of credit.

Uses:

         o        $11.3 million as partial consideration in the acquisition of
                  Jones Drilling Corporation and its related entities and $15.7
                  million for six drilling rigs from three other non-affiliated
                  entities,

         o        $89.2 million in payments on debt and

         o        $131.6 million for capital expenditures for the betterment and
                  refurbishment of both the marketable and non-marketable
                  drilling rigs, as well as the acquisition and procurement of
                  drilling equipment, to fund leasehold acquisition, exploration
                  and development of oil and natural gas properties and to fund
                  capital expenditures for our drilling and completion fluids
                  and pressure pumping segments.

         On January 5, 2001, the Company consummated the transactions
contemplated by certain agreements among the Company and Jones Drilling
Corporation, Henderson Welding, Inc., L.E.J. Truck and Crane, Inc., and L.E.
Jones Drilling Company. The acquired assets consisted of 21 drilling rigs (of
which 14 were marketable when acquired) and related equipment and approximately
$2.3 million of net working capital.

         During the nine months ended September 30, 2001, the Company paid
approximately $18.2 million in cash to the Internal Revenue Service and other
state taxing authorities for its federal and state income tax obligations. On
October 1, 2001, the Company paid, with its cash on hand, an additional $26.7
million to the Internal Revenue Service for its estimated federal income taxes
payable through that date. To date, the Company's line of credit remains fully
available.

         We believe that the current level of cash and cash equivalents,
together with cash generated from operations should be sufficient to meet our
immediate capital needs. From time to time, acquisition opportunities are
reviewed relating to our business. The timing, size or success of any
acquisition and the associated capital commitments are unpredictable. Should
further opportunities for growth requiring capital arise, we believe we would be
able to satisfy these needs through a combination of working capital, cash
generated from operations, and either debt or equity financing. However, there
can be no assurance that such capital would be available.

         The significant increases shown were reflective of increased
productivity in the contract drilling industry as evidenced by:

         o        increases in average rig utilization and in the number of
                  operating days and

         o        the addition of an average 30 drilling rigs from the third
                  quarter of 2000 to that of 2001.

         Deteriorating economic environment conditions which began in the
quarter and have continued through October 2001 have had an adverse impact on
the market prices for crude oil and natural gas. Accordingly, the demand for the
Company's contract drilling services have been negatively impacted as evidenced
by an estimated 50% average rig utilization through October 2001. Demand for the
Company's contract drilling services is not expected to increase until such
economic conditions improve.

VOLATILITY OF OIL AND NATURAL GAS PRICES AND ITS IMPACT ON OPERATIONS

         Our revenue, profitability and future rate of growth are substantially
dependent upon prevailing prices for oil and natural gas, with respect to our
contract drilling, pressure pumping and drilling and completion fluids segments.
Historically, oil and natural gas prices and markets have been volatile. Prices
are affected by market supply and demand factors as well as actions of state and
local agencies, the United States and foreign governments and international
cartels. All of these are beyond our control. Any significant or extended
decline in oil and/or natural gas prices would have a material adverse effect on
our financial condition and results of operations.

         Due to a decline in oil and natural gas prices beginning in the second
quarter of this year, demand for drilling rigs declined beginning in August and
is continuing. This decline in demand has resulted in a commensurate steep
decline in drilling rig utilization rates, which in turn has adversely impacted
our operations.

IMPACT OF INFLATION

         We believe that inflation will not have a significant impact on our
financial position or operations.

RECENTLY ISSUED ACCOUNTING STANDARDS

         The FASB issued Statement of Financial Accounting Standards No. 141,
"Business Combinations," ("SFAS No. 141") in June 2001. SFAS No. 141 addresses
financial accounting and reporting for business combinations and supersedes APB
Opinion No. 16, "Business Combinations," and FASB Statement No. 38, "Accounting
for Preacquisition Contingencies of Purchased Enterprises." SFAS No. 141 is
effective for all business combinations initiated after June 30, 2001 and
provides that such combinations are to be accounted for using the purchase
method. The Company has adopted SFAS No. 141 as of June 30, 2001.

         The FASB issued Statement of Financial Accounting Standards No. 142,
"Goodwill and Other Intangible Assets," ("SFAS No. 142") in June 2001. SFAS No.
142 addresses financial accounting and reporting for acquired goodwill and other
intangible assets and supersedes APB Opinion No. 17, "Intangible Assets." SFAS
No. 142 applies to all fiscal years beginning after December 15, 2001. The
provisions of SFAS No. 142, which the Company will adopt on January 1, 2002, are
not expected to have a material impact on the Company's consolidated financial
statements.

         The FASB issued Statement of Financial Accounting Standards No. 143,
"Accounting for Asset Retirement Obligations," ("SFAS No. 143") in July 2001.
SFAS No. 143 addresses financial accounting requirements for retirement
obligations associated with tangible long-lived assets. SFAS No. 143 is
effective beginning June 15, 2002. The provisions of SFAS No. 143 are not
expected to have a material impact on the Company's consolidated financial
statements.

         The FASB issued Statement of Financial Accounting Standards No. 144,
"Accounting for the Impairment or Disposal of Long-Lived Assets," (SFAS No. 144)
in August 2001. SFAS No. 144 addresses financial accounting and reporting for
the impairment or disposal of long-lived assets and supersedes SFAS No. 121 and
APB Opinion No. 30. SFAS No. 144 is effective beginning January 1, 2002, and is
not expected to have a material impact on the Company's consolidated financial
statements.


ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

         We currently have no exposure to market risk as we have no outstanding
balance under our credit facility with CIT. Should we incur a balance in the
future, we would have some exposure associated with the floating rate portion of
the interest charged on that balance. The credit facility, which matures on June
29, 2005, bears interest at LIBOR plus 1.75 % to 2.75% based on the Company's
twelve-month trailing EBITDA. Our exposure to interest rate risk due to changes
in LIBOR is not expected to be material.

financing of operations; continued volatility of oil and natural gas prices;
source and sufficiency of funds required for immediate capital needs and
additional rig acquisitions (if further opportunities arise); and such other
matters. The words "believes," "plans," "intends," "expected," "estimates" or
"budgeted" and similar expressions identify forward-looking statements. The
forward-looking statements are based on certain assumptions and analyses we make
in light of our experience and our perception of historical trends, current

correct any of the forward-looking information. Factors that could cause actual
results to differ materially from our expectations expressed in the
forward-looking statements include, but are not limited to, the following:
projected revenues following the merger being lower than expected; intense
competition in the contract drilling industry; low oil prices and/or natural gas
prices; adverse market conditions for contract drilling services; drill-pipe
shortages; labor shortages, primarily qualified drilling rig personnel;
insurance coverage limitations and requirements; inability to acquire additional
drilling rigs on terms favorable to us and the loss of key personnel,
particularly Cloyce A. Talbott and A. Glenn Patterson, our Chief Executive
Officer and our President and Chief Operating Officer, respectively. For a more
complete explanation of these various factors and others, see "Cautionary

ITEM 5. OTHER INFORMATION.

         The Board of Directors of Patterson-UTI Energy, Inc., at a meeting
thereof duly held on October 23, 2001, amended the Rights Agreement between
Patterson-UTI Energy, Inc. and Continental Stock Transfer & Trust Company, dated
as of January 2, 1997 (the "Rights Plan"), as follows:

         (a)      The fraction of a share of Series A Participating Preferred
                  Stock of Patterson-UTI into which each Right is exercisable
                  pursuant to the terms of the Rights Plan was changed from one
                  one-hundredth of a share of Series A Participating Preferred
                  Stock to one one-thousandth of a share of Series A
                  Participating Preferred Stock;

         (b)      The exercise price of each Right was increased from $41.50 per
                  Right (gives effect to two 2-for-1 stock splits effected since
                  the date of adoption of the Rights Plan on January 2, 1997);
                  and

         (c)      The final expiration date of the Rights Plan was changed from
                  January 2, 2007 to October 23, 2011, thereby establishing a
                  new 10-year term for the Rights Plan.

      An earlier amendment to the Rights Plan adopted by the Board of Directors
      at a meeting thereof duly held on July 1, 1999, eliminated the so-called
      "dead hand" provision from the Rights Plan through deletion of the last
      sentence of Section 27 of the Rights Plan.
