NOTES TO FINANCIAL STATEMENTS

NOTE 1 - NATURE OF BUSINESS AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

This interim financial data should be read in conjunction with the consolidated
financial statements and related notes, management's discussion and analysis and
other information included in Allis-Chalmers Corporation's ("Allis-Chalmers" or
the "Company") Annual Report on Form 10-K for the year ended December 31, 2002,
and the Current Reports on Form 8-K filed on February 20, 2003, June 12, 2003,
and July 16, 2003, respectively.

All normal and recurring adjustments considered necessary for a fair
presentation of the results of operations have been included in the unaudited
financial statements. In addition, all non-recurring adjustments necessary to
prevent the financial statements from being misleading have been included in the
unaudited financial statements. The results of operations for any interim period
are not necessarily indicative of the Company's operating results for a full
year.

ORGANIZATION OF BUSINESS

The Company was incorporated in 1913 under Delaware law. The Company reorganized
in bankruptcy in 1988, and sold all of its major businesses. In May 2001, the
Company consummated a merger in which the Company acquired OilQuip Rentals, Inc.
(OilQuip) and its wholly owned subsidiary, Mountain Compressed Air, Inc.
("Mountain Air"), in exchange for shares of the common stock, which upon
issuance represented over 85% of the outstanding common stock. In February 2002,
the Company acquired approximately 81% of the capital stock of Jens' Oilfield
Service, Inc. ("Jens'") and all of the capital stock of Strata Directional
Technology, Inc. ("Strata").

On July 2, 2003, the Company through its subsidiary Mountain Air, entered into a
joint venture agreement with a division of M-I L.L.C. ("M-I"). Both Companies
contributed assets with a book value of approximately $13 million to AirComp
L.L.C. ("AirComp"). The Company owns 55% and M-I owns 45% of AirComp. The
Company will consolidate AirComp into its financial statements in future
financial statements.

Through AirComp, Jens' and Strata, and through additional acquisitions in the
oil and natural gas drilling services industry, the Company intends to exploit
opportunities in the oil and natural gas service and rental industry. Currently,
the Company receives 80% to 85% of its revenues from natural gas drilling
services and the balance from oil drilling services; however, most of its
services can be utilized for either activity.

USE OF ESTIMATES

The preparation of financial statements in conformity with accounting principles
generally accepted in the United States of America requires management to make
estimates and assumptions that affect the reported amounts of assets and
liabilities and disclosure of contingent assets and liabilities at the date of
the financial statements, and the reported amounts of revenues and expenses
during the reporting period. Future events and their effects cannot be predicted
with certainty. Accordingly, the Company's accounting estimates require the
exercise of judgment. While management believes that the estimates and
assumptions used in the preparation of the consolidated financial statements are
appropriate, actual results could differ from those estimates. Estimates are
used for, but are not limited to, determining the following: allowance for
doubtful accounts reserves, recoverability of long-lived assets, useful lives
used in depreciation and amortization, income taxes and related valuation
allowances, and insurance and legal accruals. The accounting estimates used in
the preparation of the consolidated financial statements may change as new
events occur, as more experience is acquired, as additional information is
obtained and as the Company's operating environment changes.

NEW ACCOUNTING PRONOUNCEMENTS

In July 2002, the FINANCIAL ACCOUNTING STANDARDS BOARD ("FASB") issued SFAS No.
146, ACCOUNTING FOR COSTS ASSOCIATED WITH EXIT OR DISPOSAL ACTIVITIES ("SFAS No.
146"). SFAS No. 146 requires companies to recognize costs associated with exit
or disposal activities when they are incurred rather than at the date of
commitment to an exit or disposal plan. The provisions of SFAS No. 146 will
apply to any exit or disposal activities initiated by the Company after December
31, 2002. SFAS No. 146 is not expected to have a material effect on the results
of operations or financial position of the Company.

SFAS No. 147, ACQUISITIONS OF CERTAIN FINANCIAL INSTITUTIONS, was issued in
December 2002 and is not expected to apply to the Company's current or planned
activities.

In December 2002, the FASB approved SFAS No. 148, ACCOUNTING FOR STOCK-BASED
COMPENSATION - TRANSITION AND DISCLOSURE - AN AMENDMENT OF FASB STATEMENT NO.
123 ("SFAS No. 148"). SFAS No. 148 amends SFAS No. 123 to provide alternative
methods of transition for a voluntary change to the fair value based method of
accounting for stock-based employee compensation. In addition, SFAS No. 148
amends the disclosure requirements of SFAS No. 123 to require prominent
disclosures in both annual and interim financial statements about the method of
accounting for stock-based employee compensation and the effect of the method
used on reported results. SFAS No. 148 is effective for financial statements for
fiscal years ending after December 15, 2002. The Company will continue to
account for stock based compensation using the methods detailed in the
stock-based compensation accounting policy as disclosed in Company's Annual
Report on From 10-K for the year ended December 31, 2002.

In April 2003, the FASB issued SFAS No. 149, AMENDMENT OF STATEMENT NO. 133
ON DERIVATIVE INSTRUMENTS AND HEDGING ACTIVITIES ("SFAS No. 149").  SFAS No.
149 amends certain portions of SFAS No. 133 and is effective for all contracts
entered into or modified after June 30, 2003 on a prospective basis. SFAS No.
149 is not expected to have a material effect on the results of operations or
financial position of the Company because the Company currently has no
derivatives or hedging contracts.

In June 2003, the FASB approved SFAS No. 150, ACCOUNTING FOR CERTAIN FINANCIAL
INSTRUMENTS WITH CHARACTERISTICS OF BOTH LIABILITIES AND EQUITY (SFAS No. 150).
SFAS No. 150 establishes standards for how an issuer classifies and measures
certain financial instruments with characteristics of both liabilities and
equity. This Statement is effective for financial instruments entered into or
modified after May 31, 2003, and otherwise is effective at the beginning of the
first interim period beginning after June 15, 2003. The effect on the Company's
financial position include the fact that beginning on July 1, 2003, or
immediately subsequent to the date of this financial statement, the redeemable
convertible preferred stock and the redeemable warrants will be classified as
liabilities and not as currently shown in the mezzanine equity section of the
balance sheet. The adoption of SFAS No. 150 could also affect the Company's debt
covenant calculations, which are currently in compliance as of June 30, 2003.

NOTE 2 - ACQUISITIONS

The Company completed two acquisitions and related financing on February 6,
2002.

The Company purchased 81% of the outstanding stock of Jens Oil Field Service,
Inc. ("Jens"). Jens supplies highly specialized equipment and operations to
install casing and production tubing required to drill and complete oil and gas
wells. The Company also purchased substantially all the outstanding common stock
and preferred stock of Strata Directional Technology, Inc. ("Strata"). Strata

                                       8




provides high-end directional and horizontal drilling services for specific
targeted reservoirs that cannot be reached vertically.

The purchase price for Jens and Strata was (i) $10,250,000 in cash, (ii) a
$4,000,000 note payable due in four years, (iii) $1,000,000 for a non-compete
agreement payable for five years, (iv) 7,957,712 shares of common stock of the
Company, (v) 3,500,000 shares of a newly created Series A 10% Cumulative
Convertible Preferred Stock of the Company ("Series A Preferred Stock") and (vi)
an additional payment of $841,000 based upon Jens' working capital on February
1, 2002. In May 2002, the Company purchased the remaining minority interest in
Strata in exchange for 87,500 shares of the Company common stock.

In connection with the acquisition of Strata and Jens, the Company's bank
provided financing of $12,728,396 consisting of revolving credit facilities in
the amount of $3,500,000, term facilities in the amount of $5,696,396 and a
subordinated loan in the amount of $3,000,000.

In connection with the Strata purchase, the Company authorized the creation of
Series A Preferred Stock. 3,500,000 shares of Series A Preferred Stock were
issued to the seller, Energy Spectrum. The Series A Preferred Stock has
cumulative dividends at ten percent (10%) per annum payable in cash or
additional Series A Preferred Stock. Additionally, the Series A Preferred Stock
is convertible into common stock of the Company. The Series A Preferred Stock is
also subject to mandatory redemption on or before February 4, 2004 or earlier
from the net proceeds of new equity sales and optional redemption by the Company
at any time. The redemption price of the Series A Preferred Stock is $1.00 per
share. In addition, in connection with the Strata acquisition, Energy Spectrum
was issued warrants for 1,312,500 shares of Company common stock at an exercise
price of $0.15 per share.

The acquisitions were accounted for using the purchase method of accounting.
Goodwill and other identifiable intangible assets of $4,668,000 were recorded
with the acquisition of Strata and other identifiable intangible assets of
$1,235,000 were recorded with the acquisition of Jens.

The Company issued to the banks warrants for 1,165,000 shares of common stock at
an exercise price of $0.15 per share and 335,000 warrants to purchase common
stock at a $1.00 per share in connection with their subordinated debt financing.
All of these warrants are subject to redemption by the Company at the option of
the warrant holders for $1,500,000 after three years.

The following unaudited pro forma consolidated summary financial information
illustrates the effects of the acquisitions of Jens and Strata on the Company's
results of operations, based on the historical statements of operations, as if
the transactions had occurred as of the beginning of the period presented.

three years beginning February 6, 2002 as additional interest expense.

NOTES PAYABLE TO CERTAIN FORMER DIRECTORS - The Allis-Chalmers Board established
an arrangement by which to compensate former and continuing Board members who
had served from 1989 to March 31, 1999 without compensation. Pursuant to the

                                       11




arrangement in 1999, Allis-Chalmers issued promissory notes totaling $325,000 to
current or former directors and officers. The notes bear interest at the rate of
5%, compounded quarterly, and are due March 28, 2005. At June 30, 2003, the
notes are recorded at $378,000, including accrued interest.

REDEEMABLE WARRANTS - Associated with the issuance of the $2 million
Subordinated debt recorded by Mountain Air and the $3 million Subordinated debt
recorded by Allis-Chalmers (collectively, the "subordinated debt"), the Company
has issued redeemable warrants that are exercisable into a maximum of 1,165,000
shares of the Company's common stock at an exercise price of $0.15 per share
("Warrants A and B") and non-redeemable warrants that are exercisable into a
maximum of 335,000 shares of the Company's common stock at $1.00 per share
("Warrant C"). Warrants A and B are subject to cash redemption provisions
("puts") of $600,000 and $900,000, respectively, at the discretion of the
warrant holders beginning at the earlier of the final maturity date of the
subordinated debt or three years from the closing of the subordinated debt
(January 31, 2004 and January 31, 2005, respectively). Warrant C does not
contain any such puts or provisions. In addition, previously issued warrants to
purchase common stock of Mountain Air were cancelled. The Company has recorded a
liability of $600,000 at Mountain Air and $900,000 at Allis-Chalmers for a total
of $1,500,000 and is amortizing the effects of the puts to interest expense over
the life of the related subordinated debt instruments.

NOTE 4 - SHAREHOLDERS' EQUITY

On March 6, 2002, the Company issued 3,500,000 shares of Series A 10% Cumulative
Convertible Preferred Stock, (the "Preferred Stock"), to Energy Spectrum
Partners, LP. ("Energy Spectrum") in connection with the acquisition (the
"Strata Acquisition") from Energy Spectrum of substantially all of the common
stock and preferred stock of Strata Directional Technology, Inc.

In accordance with the Certificate of Designation, Preferences and Rights of the
Preferred Stock (the "Certificate") the Preferred Stock is convertible into a
number of shares of our common stock determined by dividing the "Liquidation
Value" of the Preferred Stock, which is $1.00 per share, by the "Conversion
Price" of the Preferred Stock. The Conversion Price was initially $0.75, but in
accordance with the Certificate was reduced on February 1, 2003, to an amount
equal to 75% of the market price calculated in accordance with the Certificate,
or $0.19.

By letter agreement dated February 19, 2003, a copy of which is attached as an
exhibit to Form 8-K filed on February 20, 2003, Energy Spectrum agreed to
increase the Conversion Price to $0.50, to vote for an amendment to our
Certificate of Incorporation to reflect the increase in the Conversion Price,
and that prior to the amendment of the Company's Certificate of Incorporation if
any Preferred Stock is converted into our common stock the Conversion Price for
such conversion shall be $0.50. The letter agreement reduces the number of
shares of common stock into which the Preferred Stock is convertible from
18,421,053 to 7,000,000 shares.

The Conversion Price is subject to adjustment pursuant to Section 11 of the
Certificate in the event of a stock split, stock dividend, reclassification, or
similar event, or in the event any other distribution is made in respect of our
common stock. Section 11 also provides that in the event we sell shares of our
common stock for less than the Conversion Price, the Conversion Price will be
reduced to such sales price.

In connection with the Strata Acquisition, we issued to Energy Spectrum a
warrant to purchase 437,500 shares of our common stock at an exercise price of
$0.15 per share, and we agreed that if we did not redeem all but one share of
the Preferred Stock on or prior to February 6, 2003, we would issue Energy
Spectrum an additional warrant to purchase 875,000 shares of our common stock at
an exercise price of $0.15 per share. On February 19, 2003, we issued such
warrant, a copy of which is attached as an exhibit to the Form 8-K filed on
February 20, 2003.

NOTE 6 - SUBSEQUENT EVENTS

The Company entered into a joint venture agreement with a division of M-I
L.L.C., and related financing on July 2, 2003. The Company through its
subsidiary, Mountain Compressed Air, Inc., and M-I L.L.C. each contributed
assets with a combined net book value of approximately $13 million to AirComp.
Mountain Compressed Air contributed substantially all of its compressed air
drilling assets with an estimated net book value of approximately $7.2 million
to AirComp. The Company will own 55% and M-I L.L.C. will own 45% of AirComp.

In connection with the transaction, AirComp obtained bank financing of $8
million (matures on June 27, 2007), of which $7.3 million was distributed to the
Company to extinguish the outstanding Mountain Compressed Air debt,
approximately $2.4 million was used to purchase equipment the Company was
leasing and $700,000 will be used by AirComp to pay transaction costs and
working capital. The debt bears interest at a floating rate, currently LIBOR
plus 0.5% annually. AirComp has the ability to borrow an additional $2 million
under its credit agreement with the bank. AirComp's bank debt is secured by
substantially all of the assets of AirComp. The Company has guaranteed all of
Mountain Compressed Air's obligations under the joint venture agreement, and
Mountain Compressed Air has guaranteed up to $2 million of AirComp's debt.

As a result of the debt repayment, the Company is in compliance with all of its
loan covenants with its Bank Lenders and classified all of its debt, except for
the debt relating to Mountain Compressed Air, as long-term instead of short-term
as previously reported in prior 10-Qs and 10-Ks.

Along with the bank financing, AirComp issued a note to M-I L.L.C. for in the
amount of $4.8 million bearing an annual interest rate of 5% in conjunction with
the joint venture. The note is due and payable when M-I sells its interest in
AirComp.

On July 15, 2003, the Company entered into a settlement agreement with the
former owners of Mountain Air Drilling Service Company (the "Sellers"). As part
of the settlement agreement, the note payable to the Sellers was reduced from
$2.2 million to $1.5 million. The note payable continues to accrue interest at a
rate of 5.75% per annum and the due date of the note payable was extended from
February 6, 2006 to September 30, 2007. The Company has not yet determined the
accounting effects of this modification to the original debt terms.

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

BACKGROUND
----------

The Company was incorporated in 1913 under Delaware law. The Company reorganized
in bankruptcy in 1988, and sold all of our major businesses. In May 2001, the
Company consummated a merger in which the Company acquired OilQuip Rentals, Inc.
(OilQuip) and its wholly owned subsidiary, Mountain Compressed Air, Inc.
("Mountain Air"), in exchange for shares of our common stock, which upon
issuance represented over 85% of our outstanding common stock. In February 2002,
the Company acquired approximately 81% of the capital stock of Jens' Oilfield
Service, Inc. ("Jens'") and all of the capital stock of Strata Directional
Technology, Inc. ("Strata").

On July 2, 2003, the Company through its subsidiary Mountain Air, entered into a
joint venture agreement with a division of M-I L.L.C. Both Companies contributed
assets with a book value of approximately $13 million to AirComp L.L.C.
("AirComp"). The Company owns 55% and M-I L.L.C. owns 45% of AirComp L.L.C.

Through AirComp, Jens' and Strata, and through additional acquisitions in the
oil and natural gas drilling services industry, the Company intends to exploit
opportunities in the oil and natural gas service and rental industry. Currently,
the Company receives 80% to 85% of our revenues from natural gas drilling
services and the balance from oil drilling services; however, most of our
services can be utilized for either activity.

CRITICAL ACCOUNTING POLICIES
----------------------------

We have identified the policies below as critical to our business operations and
the understanding of our results of operations. The impact and any associated
risks related to these policies on our business operations is discussed
throughout Management's Discussion and Analysis of Financial Condition and
Results of Operations where such policies affect our reported and expected
financial results. For a detailed discussion on the application of these and
other accounting policies, see Note 1 in the Notes to the Consolidated Financial
Statements. Note that our preparation of this Quarterly Report on Form 10-Q
requires us to make estimates and assumptions that affect the reported amount of
assets and liabilities, disclosure of contingent assets and liabilities at the
date of our financial statements, and the reported amounts of revenue and
expenses during the reporting period. There can be no assurance that actual
results will not differ from those estimates.

REVENUE RECOGNITION. Our revenue recognition policy is significant because our
revenue is a key component of our results of operations. In addition, our
revenue recognition policy determines the timing of certain expenses, such as
commissions and royalties. We follow very specific and detailed guidelines in
measuring revenue; however, certain judgments affect the application of our
revenue policy. Revenue results are difficult to predict, and any shortfall in
revenue or delay in recognizing revenue could cause our operating results to
vary significantly from quarter to quarter and could result in future operating
losses. Revenues are recognized by the Company and its subsidiaries as services
are provided.

IMPAIRMENT OF LONG-LIVED ASSETS. Long-lived assets, which include property,
plant and equipment, goodwill and other intangibles, comprise a significant
amount of the Company's total assets. The Company makes judgments and estimates
in conjunction with the carrying value of these assets, including amounts to be
capitalized, depreciation and amortization methods and useful lives.
Additionally, the carrying values of these assets are reviewed for impairment or
whenever events or changes in circumstances indicate that the carrying amounts
may not be recoverable. An impairment loss is recorded in the period in which it
is determined that the carrying amount is not recoverable. This requires the
Company to make long-term forecasts of its future revenues and costs related to
the assets subject to review. These forecasts require assumptions about demand
for the Company's products and services, future market conditions and

                                       15




technological developments. Significant and unanticipated changes to these
assumptions could require a provision for impairment in a future period.

GOODWILL AND OTHER INTANGIBLES - The Company has recorded approximately
$10,215,000 of goodwill and other identifiable intangible assets. The Company
performs purchase price allocations when it makes a business combination.
Business combinations and subsequent purchase price allocations have been
recorded for purchase of the Mountain Air, Strata and Jens' operating segments.
The excess of the purchase price after allocation of fair values to tangible
assets are allocated to goodwill and other identifiable intangibles.
Subsequently, the Company has performed its initial impairment tests and annual
valuation tests in accordance with Financial Accounting Standards Board No. 141,
BUSINESS COMBINATIONS, and Financial Accounting Standards Board No. 142,
GOODWILL AND OTHER INTANGIBLE ASSETS. These valuations required the use of
third-party valuation experts who in turn developed assumptions to value the
carrying value of the individual reporting units. Significant and unanticipated
changes to these assumptions could require a provision for impairment in a
future period.

of 2003 increased over the first six months of 2002 due to the increased
activity in the drilling market and our continued efforts to increase market
share in the Casing Services and Directional Drilling Services segments.

Gross margin ratio, as a percentage of sales, was 27.4% in the first six months
of 2003 compared with 20.7 % in the first six months of 2002. The gross margin
increased in the first six months of 2003 as compared to the first six months of
2002, which included post merger sales from February 1, 2002 through June 30,
2002 for the Casing Services and Directional Drilling segments, due to an
increase in market share and increased pricing in the Casing Services and
Directional Drilling Services segments.

Marketing and administrative expense was $2,001,000 in the first six months of
2003 compared with $1,810,000 in the first six months of 2002. The marketing and

PRO FORMA COMPARISON

The pro forma results of operations set forth below includes results of
operations of the Company for all of the first six months of 2003 and 2002 as if
the transactions had occurred as of the beginning of the periods presented.
These pro forma financial statements should be read in conjunction with the
historical financial statements included herein.

                                       17




Sales in the first six months of 2003 totaled $14,339,000 compared with pro
forma sales of $8,642,000 for the first six months of 2002. Revenues for the
first six months of 2003 increased over the first six months of 2002 due to the
increase activity in the drilling market and our continued efforts to increase
market share in the Casing Services and Directional Drilling Services segments.

Gross profit totaled $3,934,000 for a gross profit margin of 27.4% of sales in
the six months ended June 30, 2003. Pro forma gross profit for the comparable
six months in the prior year totaled $1,563,000 for a gross profit margin of
18.1% of sales. The increase in profit margin results reflects the fact that the
Company's revenues increased at a greater rate than its expenses because many of
its costs (including certain financing and equipment costs) are fixed and do not
increase with revenues.

The Company had a net loss attributed to common shareholders' of ($513,000), or
($0.03) per common share, for the first six months of 2003 compared to a pro
forma net loss of ($1,656,000), or ($0.09) per common share, for the first six
months of 2002.

                                             --------------  -------------- -------------- ------------- ----------


FINANCIAL CONDITION AND LIQUIDITY
---------------------------------

Cash and cash equivalents totaled $30,000 at June 30, 2003, a decrease from
$146,000 at December 31, 2002. Cash flows provided by operations totaled
$1,673,000 in the first six months of 2003 compared to the $34,000 utilized in
the prior year.

Net trade receivables at June 30, 2003 were $6,006,000. This increased
significantly from the December 31, 2002 balance of $4,409,000 due to the
increase in operating activity and increased activities with customers with
longer payment cycles.

Net property, plant and equipment were $16,139,000 at June 30, 2003. Capital
expenditures for the six months ended June 30, 2003 were $821,000. Capital
expenditures for the year 2003 are projected to be approximately $3,000,000.

Trade accounts payable at June 30, 2003 were $3,490,000. This increased
significantly from the December 31, 2002 balance of $2,106,000 due to the
increase in operating activity without an adequate improvement in cash flows.

                                       18




Other current liabilities, excluding the current portion of long-term debt, were
$2,605,000 including interest in the amount of $1,279,000, accrued salary and
benefits in the amount of $213,000, and accrued expenses of $1,113,000. All of
these balance sheet accounts increased significantly from the December 31, 2002
balances due to the increase in revenues.

Long-term debt was $20,259,000 at June 30, 2003 including current maturities.

In addition to the debt discussed above, the Company had available lines of
credit totaling $2,559,000 at June 30, 2003, of which $597,000 was available and
unused.

Our long-term capital needs are to refinance our existing debt, provide funds
for existing operations, redeem the Series A Preferred Stock (which is subject
to mandatory redemption on February 1, 2004) and to secure funds for
acquisitions in the oil and gas equipment rental and services industry. In order
to pay our debts as they become due, including the amounts due to the Bank
Lenders described above we will require additional financing, which may include
the issuance of new warrants or other equity or debt securities, as well as
secured and unsecured loans. Any new issuance of equity securities would dilute
existing shareholders.

By letter agreement dated February 19, 2003, Energy Spectrum agreed to increase
the Conversion Price to $0.50, to vote for an amendment to our Certificate of
Incorporation to reflect the increase in the Conversion Price, and that prior to
the amendment of the Company's Certificate of Incorporation if any Preferred
Stock is converted into our common stock the Conversion Price for such
conversion shall be $0.50. The letter agreement reduces the number of shares of
common stock into which the Preferred Stock is convertible from 18,421,053 to
7,000,000 shares.

In connection with the Strata Acquisition, we issued to Energy Spectrum a
warrant to purchase 437,500 shares of our common stock at an exercise price of
$0.15 per share, and we agreed that if we did not redeem all but one share of
the Preferred Stock on or prior to February 6, 2003, we would issue Energy
Spectrum an additional warrant to purchase 875,000 shares of our common stock at
an exercise price of $0.15 per share. On February 19, 2003, we issued such
warrant.

RECENT DEVELOPMENTS - JOINT VENTURE WITH M-I L. L.C. AND MOUNTAIN AIR DRILLING
SERVICE COMPANY NOTE PAYABLE REDUCTION

We entered into a joint venture agreement with a division of M-I L.L.C., and
related financing on July 2, 2003. The Company through its subsidiary, Mountain
Compressed Air, Inc., and M-I L.L.C. each contributed assets with a combined net
book value of approximately $13 million to AirComp. Mountain Compressed Air
contributed substantially all of its compressed air drilling assets with an
estimated net book value of approximately $7.2 million to AirComp. The Company
will own 55% and M-I L.L.C. will own 45% of AirComp.

In connection with the transaction, AirComp obtained bank financing of $8
million (matures on June 27, 2007), of which $7.3 million was distributed to the
Company to extinguish the outstanding Mountain Compressed Air debt,
approximately $2.4 million was used to purchase equipment the Company was
leasing and $700,000 will be used by AirComp to pay transaction costs and
working capital. The debt bears interest at a floating rate, currently LIBOR
plus 0.5% annually. AirComp has the ability to borrow an additional $2 million
under its credit agreement with the bank. AirComp's bank debt is secured by
substantially all of the assets of AirComp. The Company has guaranteed all of
Mountain Compressed Air's obligations under the joint venture agreement, and
Mountain Compressed Air has guaranteed up to $2 million of AirComp's debt.

                                       19




As a result of the debt repayment, the Company is in compliance with all of its
loan covenants with its Bank Lenders and classified all of is debt except for
the debt relating to Mountain Compressed Air, as long-term instead of short-term
as previously reported in prior 10-Qs and 10-Ks.

Along with the bank financing, AirComp issued a note to M-I L.L.C. for in the
amount of $4.8 million bearing an annual interest rate of 5% in conjunction with
the joint venture. The note is due and payable when M-I sells its interest in
AirComp.

On July 15, 2003, the Company entered into a settlement agreement with the
former owners of Mountain Air Drilling Service Company ("the Sellers"). As part
of the settlement agreement, the note payable to the Sellers was reduced from
$2.2 million to $1.5 million. The note payable continues to accrue interest at a
rate of 5.75% per annum and the due date of the note payable was extended from
February 6, 2006 to September 30, 2007. The Company has not yet determined the
accounting effects of this modification to the original debt terms.

PART II.  OTHER INFORMATION

ITEM 1. LEGAL PROCEEDINGS

On January 15, 2003, the Company filed a lawsuit against the former owners
(Rodney and Linda Huskey) of Mountain Air Drilling Service Company, Inc. nka
Pattongill & Murphy, Inc. in the U.S. District Court for the Southern District
of Texas "Houston Division." The Company asserted claims for breach of
representations and warranties and non-compete covenants made in connection with
the purchase of Mountain Compressed Air. In July 2003, the Company entered into
a settlement agreement with the former owners of Mountain Air Drilling Service
Company. As part of the settlement agreement, the principal due on the note
payable to Pattongill & Murphy, Inc., (sellers) was reduced from $2.2 million to
$1.5 million. The note payable continues to accrue interest at a rate of 5.75%
per annum and the due date of the note payable was extended from February 6,
2006 to September 30, 2007

ITEM 3. DEFAULT UPON SENIOR SECURITIES

On July 16, 2002, the Company's lenders declared the Company and it's
subsidiaries to be in default under numerous credit agreements with Wells Fargo
Bank and its affiliates (the "Bank Lenders"). The defaults resulted primarily
from failures to meet financial covenants. As a result of these defaults the
Bank Lenders imposed default interest rates and suspended interest payments
(aggregating $375,000 through June 30, 2003) on a $4.0 million subordinated
seller note (the "Seller Note") issued to Jens Mortensen in connection with the
Jens' acquisition, and suspended interest payments (aggregating $244,000 through
June 30, 2003) on a $3.0 million subordinated bank note (the "Subordinated Bank
Note") issued in connection with the Jens' acquisition, which resulted in Jens'
default under the terms of both notes. Pursuant to the terms of inter-creditor
agreements between the lenders, the holders of such obligations were precluded
from taking action to enforce such obligations without the consent of the Bank
Lenders.

Effective January 1, 2003 the Company entered into Amendment and Forbearance
Agreements (the "Forbearance Agreements"), which amended certain operating
Covenants. In addition the Bank Lenders agreed to forbear from taking action
(but did not waive the underlying defaults) with respect to the alleged defaults
until June 30, 2003.

On July 2, 2003, the Company entered into a joint venture agreement pursuant to
which it contributed substantially all of the assets of its Mountain Compressed
Air subsidiary to AirComp, as described in "Item 3 -- Managements Discussion and
Analysis of Financial Condition and Results of Operations - Recent Developments
- Joint Venture With M-I L.L.C." As a result of this transaction, the Company
repaid certain debts due to the Bank Lenders and is now in compliance with its
agreements with the Bank Lenders. The Company is in the process of obtaining a
waiver of past defaults from the Bank Lenders.

The Company is paying current interest on the Subordinated Note and has paid
$40,000 of past-due interest on the Subordinated Note. As of August 10, 2003,
the Company owed an aggregate of $604,000 for past-due interest on the Seller
Note and the Subordinated Bank Note.
