TIDEWATER INC.
NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

(1)      Interim Financial Statements

         The consolidated financial information for the interim periods
         presented herein has not been audited by independent accountants, but
         in the opinion of management, all adjustments (consisting only of
         normal recurring adjustments) necessary for a fair presentation of the
         condensed consolidated balance sheets and the condensed consolidated
         statements of earnings and cash flows at the dates and for the periods
         indicated have been made.  Results of operations for interim periods
         are not necessarily indicative of results of operations for the
         respective full years.

(2)      Earnings Per Share

         Primary and fully diluted earnings per share are computed on the
         weighted average number of shares and dilutive equivalent shares of
         common stock (stock options and restricted stock grants) outstanding
         during each period using the treasury stock method.

(3)      Commitments and Other Matters

         An employment and consulting agreement exists with the company's
         chairman of the board and chief executive officer whereby he will
         continue as an employee until the 1994 annual stockholders meeting
         (October 20, 1994) and thereafter for a period of three years will
         serve as a consultant to the company.  The terms of the employment
         agreement provide, among other things, for an annual salary/consulting
         fee.  An employment agreement exists with the company's president  and
         chief operating officer whereby he will serve in such capacity until
         the 1994 annual stockholders meeting, and thereafter serve as chairman
         of the board, president and chief executive officer for three years.
         The terms of the employment agreement provide for an annual base
         salary and certain other benefits, including 70,000 shares of
         restricted common stock of the company.  These restricted shares vest
         at varying intervals when the average sales price of the common stock
         reaches certain predetermined levels.  Compensation continuation
         agreements exist with all other officers of Tidewater Inc., whereby
         each receives compensation and benefits in the event that their
         employment is terminated following certain events relating to a change
         in control of the company.  The maximum compensation amount that could
         be paid under the compensation continuation agreements, based on
         present salary levels, is approximately $6,100,000.  The amount that
         could be paid for certain benefits is not presently determinable.

(4)      Income Taxes

         Income tax expense for interim periods is based on estimates of the
         effective tax rate for the entire fiscal year.  The effective tax rate
         was 37% for the quarter and six-month period ended September 30, 1994.
         For the quarter ended September 30, 1993 additional income tax expense
         of approximately $1.9 million was recorded for the revaluation of
         deferred tax assets and liabilities at the higher statutory income tax
         rates contained in the Omnibus Budget Reconciliation Act passed by
         Congress in August 1993.  The effective tax rate for the quarter and
         six-month period ended September 30, 1993,

         exclusive of the $1.9 million of additional income tax expense, was
         34%.

         million in cash. The proposed acquisition will be accounted for as a
         purchase and is subject to certain regulatory approvals. It is
         anticipated that the acquisition, if approved, will be consummated by

INDEPENDENT AUDITORS' REPORT



The Board of Directors and Shareholders of Tidewater Inc.:


We have reviewed the condensed consolidated balance sheet of Tidewater Inc. and
subsidiaries as of September 30, 1994 and the related condensed consolidated
statements of earnings and cash flows for the three-month and six-month periods
ended September 30, 1994 and 1993.  These financial statements are the
responsibility of the Company's management.

We conducted our review in accordance with standards established by the
American Institute of Certified Public Accountants.  A review of interim
financial information consists principally of applying analytical procedures to
financial data and making inquiries of persons responsible for financial and
accounting matters.  It is substantially less in scope than an audit conducted
in accordance with generally accepted auditing standards, the objective of
which is the expression of an opinion regarding the financial statements taken
as a whole.  Accordingly, we do not express such an opinion.

Based on our review, we are not aware of any material modifications that should
be made to the condensed consolidated financial statements referred to above
for them to be in conformity with generally accepted accounting principles.

We have previously audited, in accordance with generally accepted auditing
standards, the consolidated balance sheet of Tidewater Inc. as of March 31,
1994, and the related consolidated statements of earnings, stockholders'
equity, and cash flows for the year then ended (not presented herein); and in
our report dated May 5, 1994 we expressed an unqualified opinion on those
consolidated financial statements.  In our opinion the information set forth in
the accompanying condensed consolidated balance sheet as of March 31, 1994 is
fairly presented, in all material respects, in relation to the consolidated
balance sheet from which it has been derived.

                      MANAGEMENT'S DISCUSSION AND ANALYSIS

This discussion and analysis of financial position and results of operations
should be read in conjunction with the unaudited condensed consolidated
financial statements and the related disclosures.

Fiscal 1995 second quarter operating performance was consistent with the second
quarter of fiscal 1994. Domestically, market conditions are good, although not
as good as a year ago. Internationally, market conditions overall remain
relatively stable.

LIQUIDITY AND CAPITAL RESOURCES

Fiscal 1995 six-month operating activities generated cash in excess of amounts
generated for the corresponding period of fiscal 1994.  The amount of cash
generated from operations is primarily determined by the overall level of
Marine operating margins (defined as Marine revenues less Marine operating
expenses, excluding depreciation).  Fiscal 1995 six-month Marine operating
margins were greater than the respective fiscal 1994 six-month amount primarily
because of higher day rates for the domestic-based vessel fleet.  Operating
activities have generated and continue to generate cash in excess of amounts
required to satisfy current obligations.  Utilization levels and day/rental
rates expected for the remainder of fiscal 1995 for the Marine vessel fleet and
Compression rental equipment should maintain this condition.

Investing activities for the three-month and six-month periods ended September
30, 1994 rose significantly above corresponding amounts consumed during the
three-month and six-month periods ended September 30, 1993.  The principal
components that determine the amount of cash used in investing activities are
additions to properties and equipment and proceeds from sales of assets.

=============================================================================
</TABLE>

For the quarter ended September 30, 1994 the Marine segment purchased two
offshore tugs. The Marine segment also acquired a supply vessel and a crewboat
previously leased by the company.  Compression's equipment additions for the
quarters ended September 30, 1994 and 1993 are for the purchase of
approximately 375 and 120 gas compressors, respectively.  Because current
economic conditions generally do not produce an adequate return on investment
relative to the costs of new construction, expansion of the Marine vessel fleet
and Compression rental fleet, for the most part, will continue to come from
existing excess industry supplies.

Fiscal 1995 second quarter financing activities consumed significantly less
cash than the amount for the corresponding period of the prior fiscal year due
to a significant reduction in principal payments on long-term debt.  Fiscal
1994 second quarter financing activities included $57.6 million for the early
extinguishment and associated prepayment penalties of notes due in quarterly
installments through 1999.  Principal payments in the current quarter consist
of normal scheduled debt repayments on the remaining capitalized lease
obligations.

Continued dividend payments are subject to declaration by the Board of
Directors and are subject to limitation by the Company's revolving credit and
term loan agreement.

On October 18, 1994, the company entered into an agreement to purchase the
natural gas compression assets of Halliburton Company for $205 million in cash.
The proposed acquisition will be accounted for as a purchase and is subject to
certain regulatory approvals.  It is anticipated that the acquisition, if
approved, will be consummated by December 31, 1994.

</TABLE>

Compared with the same quarter of fiscal 1994 and the first quarter of fiscal
1995, fiscal 1995 second quarter consolidated revenues declined approximately
2.2% and 1.6%, respectively.  Earnings before income taxes for the three-month
period ended September 30, 1994 rose 16.3% above the fiscal 1994 second quarter
amount but dropped 8.3% below the prior quarter amount.  The increase in
current quarter pre-tax earnings over the corresponding amount for the same
quarter a year ago is primarily attributable to considerably lower interest
expense and higher Compression operating profits.  Lower interest expense is a
direct result of the retirement of long-term debt during fiscal 1994 and the
early redemption of the convertible subordinated debentures in April 1994.
Higher Compression operating profits in the current quarter compared to the
year ago period resulted primarily from higher utilization of gas compressors.
Overall, fiscal 1995 second quarter Marine operating profit did not materially
change from the year ago level because the increase in operating profit for the
domestic-based vessel fleet due to higher vessel day rates, was entirely offset
by lower foreign operating profit as a result of a significant drop in the size
of the foreign-based vessel fleet.

The decline in fiscal 1995 second quarter pre-tax earnings compared with the
prior quarter's amount is principally due to lower Marine operating profits.
Marine operating profits for the quarter ended June 30, 1994 included
approximately  $1.7 million of refunds resulting from the settlement of prior
years' property tax disputes and $.8 million of higher gains on sales of
assets.

Fiscal 1995 six-month consolidated revenues were generally flat compared with
the same period of fiscal 1994.  However, fiscal 1995 six-month pre-tax
earnings rose approximately 39.5% above the fiscal 1994 six-month pre-tax
amount.  Fiscal 1995 six-month earnings includes approximately $1.7 million of
property tax refunds, $1.8 million of higher gains on sales of assets,
considerably lower interest expense, as explained above, and higher Compression
operating profits.  Higher Compression operating profits for the six-month
period ended September 30, 1994 compared with the year ago period is due to
higher utilization of a larger fleet of gas compressors.

Net earnings for the quarter and six-month period ended September 30, 1993
included approximately $1.9 million of additional income tax expense for the
cumulative effect of revaluing deferred tax assets and liabilities at the
higher statutory income tax rates contained in the Omnibus Budget
Reconciliation Act passed in August 1993.

Net earnings for the current quarter and six-month period were also adversely
affected by a higher effective tax rate of 37% as compared with 34% for the
corresponding periods of fiscal 1994, excluding the cumulative effect of the
new tax law passed by Congress in August 1993.  The higher effective tax rate
is primarily due to the exhaustion of book-based net operating loss
carryforwards.

The extraordinary item for the quarter ended September 30, 1993 resulted from
the early extinguishment of $51.1 million of long-term debt.  The extraordinary
item consists of a $4.2 million after-tax prepayment penalty and the write-off
of associated deferred finance costs of $.3 million.

Professional services for the six-month period ended September 30, 1993
includes approximately $350,000 of costs associated with a secondary stock
offering.  The increase in current quarter and six-month other general and
administrative expense above the respective prior year levels is primarily due
to higher reserves for uncollectible accounts.



MARINE SEGMENT

The marine segment provides a diverse range of services and equipment to the
offshore oil and gas industry.  Because operating costs and depreciation do not
change proportionally with changes in revenues, the amount of operating profit
for the Marine segment is primarily determined by vessel fleet utilization and
day rates. Operating margins from brokered vessels and shipyard activity
generally contribute nominally to Marine operating profit.

Revenues for the Marine segment for the quarters and six-month periods ended
September 30 and for the quarter ended June 30, 1994 consist of the following:

Marine fleet utilization is affected primarily by market conditions.  It is
also influenced to a lesser degree by drydockings to satisfy safety and
inspection requirements.  Marine vessels must undergo periodic inspections to
remain properly classified and certified. These inspections, whenever possible,
are done during seasonally slow periods to minimize the impact on vessel
operations and are only done if the vessel is considered to have continuing
economic viability.  The following table compares day-based Marine fleet
utilization percentages by vessel class and in total for the quarters and
six-month periods ended September 30 and for the quarter ended June 30, 1994:

</TABLE>

The domestic fleet consist of vessels operating in U.S. waters while the
foreign fleet consist of vessels operating outside U.S. waters.

Current quarter and six-month utilization of the domestic-based vessel fleet
fell below the respective year ago levels because of decreased demand for
offshore marine services in the U.S. Gulf of Mexico.  Utilization of the
domestic-based vessel fleet for the three-month period ended September 30, 1994
was unchanged from the prior quarter level due to a continued favorable level
of demand for offshore marine services in the U.S. Gulf of Mexico despite lower
U.S. natural gas prices. Demand for offshore marine services was consistent
with the prior quarter because of the long-term outlook for higher U.S. natural
gas prices. Lower utilization of a smaller foreign-based vessel fleet for the
current quarter and six-month period compared with the year ago quarter and
six-month period is primarily attributable to significantly lower activity for
the inland towing fleet in Nigeria.  The remainder of the foreign-based vessel
fleet for the current quarter and six-month period has operated at utilization
levels consistent with the levels experienced for the respective year ago
periods.

Marine vessel day rates are primarily determined by the demand created through
the level of offshore exploration, development and production spending by
energy exploration and production companies.  Suitability of equipment, the
degree of service provided and the overall supply of marine service vessels
also influence vessel day rates.  The following table provides a comparison of
average vessel day rates by class and in total for the quarters and six-month

Although average vessel day rates for the domestic-based vessel fleet for the
current quarter and six-month period are higher than they were for the
corresponding periods of fiscal 1994, they continued to decline from the fiscal
1995 first quarter level.  This is primarily due to the continued over supply
of vessels in the U. S. Gulf of Mexico which began in the fourth quarter of
fiscal 1994 and has continued for most of fiscal 1995.  Day rates for the
foreign-based vessel fleet have remained relatively stable over the past twelve
months.  Near-term improvement in average vessel day rates for the
domestic-based vessel fleet may occur if demand for offshore marine services
increases in the U. S. Gulf of Mexico.  Average day rates for the foreign-based
vessel fleet are not expected to change materially due to present market
conditions.  Long-term improvement in average vessel day rates for the
worldwide fleet may result if oil and gas industry analysts' predictions of
higher oil and gas prices materialize.

</TABLE>

The drop in the average size of the foreign-based vessel fleet from 352 a year
ago to the current 321 is primarily due to several vessels being withdrawn from
active service due to age and anticipated high repair and maintenance costs,
the transfer of vessels to the domestic-based vessel fleet and the return of
vessels to their owners which could not be operated profitably.  As the Marine
vessel fleet ages additional vessels may be withdrawn from active service.

</TABLE>

Changes in fleet size and utilization are the principal factors which cause
fluctuations in the amount of crew costs.  Lower crew costs for the quarter and
six-month period ended September 30, 1994 compared with the corresponding year
ago periods is primarily the result of a decrease in average fleet size
combined with the lower activity level of the domestic-based vessel fleet.  The
absence of significant new vessel construction within the energy services
industry over the past 10 to 12 years has caused the average age of the
Company's Marine vessel fleet to rise.  Currently the average age of the
Company's Marine vessel fleet is approximately 16 years.  Though primarily
dictated by regulatory agencies, the scheduling of vessel drydockings together
with the age of the vessels affects the amount of repair and maintenance
expense in any period.  Vessel drydockings, whenever possible, are scheduled to
minimize any impact on revenues.  Higher vessel insurance costs for the current
quarter and six-month period are, in part, the result of a much tougher
insurance market which is unwilling to provide past levels of coverage at the
rates experienced in prior periods.

Gains from sales of assets contributed $1.5 million and $3.8 million for the
quarter and six-month period ended September 30, 1994, respectively.  For the
quarter and six-month period ended September 30, 1993, gains from asset sales
contributed $ 1.6 million and $2.0 million, respectively.

COMPRESSION SEGMENT

The Compression segment provides natural gas and air compression services and
equipment for a variety of applications primarily in the oil and gas and
petrochemical industries. It also designs, fabricates and installs engineered
compressor systems.  Compression operating profit is significantly affected by
the mix of sales and rental revenues because gross profits on sales are
generally less than operating margins for rental revenues.

Compression segment revenues are compared in the following table on a dollar
basis and as a percentage of total Compression revenues for the quarters and
six-month periods ended September 30 and for the quarter ended June 30, 1994:

Gas compressor utilization is affected primarily by natural gas storage levels
and by the number and age of producing oil and gas wells which, in turn, are
dependent upon the price levels of oil and natural gas.  Air compressor
utilization is heavily dependent upon short-term customer needs.  Suitability,
availability and rental rates for equipment are also major factors which affect
utilization of both gas and air compression equipment.  Gas compressor rentals
are generally for a longer term than are air compressor rentals.

</TABLE>

Fiscal 1995 second quarter and six-month gas compressor utilization climbed
above the corresponding levels of fiscal 1994 because of higher demand for
natural gas compression services.  Despite a decline in the price of U.S.
natural gas, demand for natural gas compression services remained firm during
the current quarter because of the long-term favorable outlook for U.S. natural
gas prices.  Six-month gas compressor rental revenues also grew as a result of
a larger gas compressor fleet.

Fiscal 1995 second quarter and six-month air compressor utilization fell below
year ago levels due to continued weak demand for air compression services.

Operating costs of the Compression segment consist of the following for the
quarters and six-month periods ended September 30 and for the quarter ended
June 30, 1994:

Field operating expenses relate to gas and air compressor rental operations.
Field operating expenses are generally consistent from period-to-period and
usually vary in the short-term due to fluctuations in the level of repairs and
maintenance expense.  Long-term growth in field operating expenses will occur
primarily as a result of increased fleet size and general inflationary factors.
Costs of sales consist primarily of wages and benefits and material costs
associated with the design, fabrication and installation of packaged compressor
systems.

Gains from sales of assets have contributed $.6 million and $.7  million for
the quarter and six-month period ended September 30, 1994.  For the quarter and
six-month period ended September 30, 1993 gains from sales of assets
contributed $.7 million to segment operating profits.

On September 30, 1994 the Compression segment purchased, for $35 million in
cash, all of the assets of Brazos Gas Compressing Company, a subsidiary of
Mitchell Energy & Development Corporation.  The purchase includes 370 gas
compressors aggregating more than 58,000 horsepower and increases the gas
compressor fleet to approximately 1,400 units and 245,000 horsepower.  The
purchase had no effect on current quarter segment revenues or operating
profits.


INFLATION AND CURRENCY FLUCTUATIONS

Because of its significant foreign operations, the company is exposed to
currency fluctuations and exchange risks.  To minimize the financial impact of
these items the company attempts to contract a majority of its services in
United States dollars.

Day-to-day operating costs are generally affected by inflation.  However,
because the energy services industry requires specialized goods and services,
general economic inflationary trends may not affect the company's operating
costs.  The major impact on operating costs is the level of offshore
exploration and development spending by energy exploration and production
companies.  As this spending increases, prices of goods and services used by
the oil and gas industry and the energy services industry will increase.
Future improvements in vessel day rates and compressor rental rates may buffer
the company from the inflationary effects on operating costs.

ENVIRONMENTAL MATTERS

During the ordinary course of business the company's operations are subject to
a wide variety of environmental laws and regulations.  The company attempts to
comply with these laws and regulations in order to avoid costly accidents and
related environmental damage.  The company is currently involved in litigation
with the Environmental Protection Agency concerning the disposal of oilfield
wastes.  In the opinion of management, the ultimate liability with respect to
the litigation will not have a material adverse effect on the company's
financial position.

extent permitted by applicable law, as may be necessary in order for Purchaser
to obtain the benefit and/or assume the obligations thereunder.  Such actions
may include (a) the Selling Entities designating the Purchaser as the Selling
Entities' subcontractor, agent or representative for purposes of performing
such contracts and the Selling Entities collecting monies due under such

                 and Assumed Liabilities as of the Closing Date prepared in

                 Final Closing Balance Sheet shall be, prepared from the books
                 and records of the Selling Entities in accordance with United
                 States generally accepted accounting principles ("GAAP").  In
                 addition, the Final Closing Balance Sheet, and the financial
                 information from





                                       9
<PAGE>   16
                 which it is derived, shall be prepared on a basis consistent
                 with that used in the preparation of the Financial Statements
                 and the Adjusted June Balance Sheet.

                          (ii)    Within thirty (30) days following the Closing
                 Date, Seller, with the assistance and cooperation of
                 Purchaser, shall prepare and deliver to Purchaser a statement
                 of Assets and Assumed Liabilities as of the Closing Date (the
                 "PRELIMINARY CLOSING BALANCE SHEET"), prepared as provided in
                 paragraph (i) above.  Purchaser shall have ten (10) business
                 days following its receipt of the Preliminary Closing Balance
                 Sheet (the "REVIEW PERIOD"), to review the same for compliance
                 with paragraph (i) above.  During such review period, the
                 Selling Entities shall, upon request of the Purchaser, grant
                 reasonable access to their books and records for the purpose
                 of permitting Purchaser to verify the information disclosed in
                 the Preliminary Closing Balance Sheet.  On or before the
                 expiration of the Review Period, Purchaser shall deliver to
                 Seller a written statement accepting or objecting to the
                 Preliminary Closing Balance Sheet.  In the event that
                 Purchaser shall object to the Preliminary Closing Balance
                 Sheet, such statement shall include a detailed itemization of
                 Purchaser's objections and its reasons therefor.  Objections,
                 if any, shall be limited to transactions occurring subsequent
                 to June 30, 1994.  If no such statement is delivered by
                 Purchaser to Seller within the Review Period, Purchaser shall
                 be deemed to have accepted the Preliminary Closing Balance
                 Sheet for purposes of determining any adjustments to the
                 Estimated Purchase Price.

                          (iii)   In the event that Purchaser shall accept or
                 shall be deemed to have accepted the Preliminary Closing
                 Balance sheet as prepared and delivered by Seller, the
                 Preliminary Closing Balance Sheet shall constitute the Final
                 Closing Balance Sheet for purposes of determining any
                 adjustment to the Estimated Purchase Price.  In the event,
                 however, that Purchaser shall object to the Preliminary
                 Closing Balance Sheet within the Review Period, Purchaser and
                 Seller shall promptly meet and in good faith attempt to
                 resolve such objection(s).  Any such objection(s) which cannot
                 be resolved between Purchaser and Seller within thirty (30)
                 days following Seller's receipt of Purchaser's statement of
                 objection(s) shall be resolved in accordance with the
                 procedures set forth in Section 3.03(e).  The Preliminary
                 Closing Balance Sheet, as adjusted to reflect the adjustments
                 agreed upon by the Parties or determined in accordance with
                 Section 3.03(e), shall constitute the Final Closing Balance
                 Sheet for purposes of determining any adjustment to the
                 Estimated Purchase Price.

                 (c)      ADJUSTMENT AND SETTLEMENT OF PURCHASE PRICE.  In the
event that the amount of the Closing Net Assets as finally determined is
greater or less than the amount of the June 30 Net Assets, such excess or
deficiency shall be referred to as the "ADJUSTMENT."  On the third business day
following the date upon which the Final Closing Balance Sheet as provided for
in Section 3.03(b)(iii) is determined, Purchaser shall pay to Seller (if the
Closing Net Assets are greater than the June 30 Net Assets), or Seller shall
pay to Purchaser (if the June 30 Net





                                       10
<PAGE>   17
Assets are greater than the Closing Net Assets), the amount of the Adjustment.
Any cash payment of the Adjustment shall be made by wire transfer of
immediately available United States funds.  Any such payment required to be
made to Seller shall be transferred to the bank account set forth in Section
3.03(a).  Any such payment required to be made to Purchaser shall be
transferred to the Purchaser's bank account identified in a written notice to
Seller.

                 (d)      ALLOCATION OF PURCHASE PRICE.  The consideration
given by Purchaser under this Agreement (including, without limitation, the
payment of the Purchase Price and the assumption of the Assumed Liabilities)
shall be allocated first between Seller and Seller's Affiliate and thereafter,
as to that portion of the Assets which are owned by the Seller at the Closing,
in accordance with section 1060 of the Internal Revenue Code of 1986, as
amended (the "CODE") and the regulations under the Code.  Schedules setting
forth such proposed allocations shall be prepared by Purchaser and delivered to
the Selling Entities within one hundred twenty (120) days following the Closing
Date.  The determination of the amount of consideration paid by Purchaser,
including the Assumed Liabilities, and its allocation as set forth on such
schedules shall be reasonably determined by Purchaser and shall be reasonably
satisfactory to the Selling Entities.  Purchaser and the Selling Entities agree
to make such allocations in filing their respective tax returns or declarations
for applicable United States and Canadian income tax purposes.

                 (e)      ACCOUNTING OBJECTIONS.  Should the Selling Entities
and Purchaser not be able to resolve such objections as may be raised with
respect to the Preliminary Closing Balance Sheet, the Final Closing Balance
Sheet or adjustments to the Estimated Purchase Price (collectively, the
"ACCOUNTING OBJECTIONS"), the objections shall be submitted to a binding
arbitration to be conducted by the independent public accounting firm of AA
which shall represent Seller and the independent public accounting firm of KPMG
Peat Marwick LLP which shall represent Purchaser.  Should AA and KPMG Peat
Marwick LLP be unable to agree on the resolution of the Accounting Objections,
after negotiating in good faith for a period of thirty (30) days, the same
shall be submitted to Deloitte & Touche for a binding resolution.

         3.04    ASSUMPTION OF LIABILITIES.  Purchaser shall assume at the
Closing and agrees to pay, honor and discharge in accordance with the terms
thereof all of the Assumed Liabilities.  The term "ASSUMED LIABILITIES" shall
mean only the following liabilities and obligations relating to the Business
or the Assets:

                 (a)      ASSIGNED CONTRACTS.  Any and all liabilities,
obligations and commitments of the Business that arise out of or relate to the
Assigned Contracts listed on Schedule 2.01(a)(3), but in any case, not
including any liability for any breach thereof occurring prior to the Closing;

                 (b)    TAXES.  Any and all taxes which may be applicable to
the Business or Assets with respect to periods beginning with the Closing, or
arising from events or occurrences on or after the Closing, including without
limitation, income, ad valorem, personal property, sales, value added, goods
and services, use or transfer taxes resulting from the sale of the Assets to

                 (a)      RETENTION.  Purchaser shall retain for a period of

and their representatives will be granted, on reasonable advance notice,
reasonable access to all such books and records during normal business hours.
In addition, the Selling Entities shall have the right to make abstracts or

of its ability with the Selling Entities' representatives and agents (i) in

Entities pursuant to Section 8.01(b) hereof, or (ii) in prosecuting or
defending any legal or administrative proceeding relating to the Assets,
Assumed Liabilities or the Business (other than a dispute between the parties).

documents in Purchaser's possession as requested and using its best efforts to
encourage its employees to testify as witnesses, appear for depositions and

and expenses incurred with respect to the foregoing.

the extent that Purchaser is not fully reimbursed by a manufacturer of the
goods subject to Manufacturer's Warranties) for the cost (determined as
provided herein below) incurred by Purchaser to perform Warranty Work which is
required as a result of either (i) a failure by the Selling Entities prior to
the Closing to perform adequate service and repair work on compression
equipment included in the Assets, or (ii) a failure by the Selling Entities
prior to the Closing to properly equip a job to satisfy the requirements of
such job as requested by the customer.  The cost to be reimbursed by Seller to
Purchaser for service and repair work as provided herein above shall be the sum
of (i) Purchaser's actual cost of parts and other materials and (ii)
Purchaser's labor cost, which shall be reimbursed at a rate of $40.00 per hour.

         6.04    EMPLOYEES OF THE BUSINESS AND SEVERANCE COSTS.  The employees
of the Selling Entities who are working for the Business on the Closing Date
are herein referred to as the "BUSINESS EMPLOYEES".

         Not later than the second business day following the Closing Date
Purchaser shall make a written offer of employment to such of the Business
Employees as Purchaser selects.  Such offer of employment shall be held open by
Purchaser for five days and shall state the salary and other compensation to be
paid, the title and duties and the location of employment for the position so
offered.

         As used herein, the term "TERMINATING BUSINESS EMPLOYEE" shall mean
Business Employees (i) who do not receive from Purchaser a comparable offer of
employment within a 50-mile radius of such person's place of employment
immediately prior to the Closing Date and (ii) whose employment is terminated
by the Selling Entities within 30 days after the Closing Date; provided,
however, that a Business Employee shall not be considered to be a Terminating
Business Employee if (A) he or she is employed by any Affiliate of the Selling
Entities or (B) under the circumstances described in the first sentence of the
following paragraph; provided further, however, that any person who would be a
Terminating Business Employee but for the fact that the Selling Entities
continued to employ such person after the Closing Date in order to fulfill
their obligations under the Transition Services Agreement and who is promptly
terminated thereafter, shall be considered to be a Terminating Business
Employee.

         If a Business Employee receives from Purchaser a comparable offer of
employment at a location within a 50 mile radius of such person's place of
employment immediately prior to the Closing Date as he or she was employed by
the Selling Entities and such Business Employee rejects such offer or allows it
to lapse after five days, then thereafter such person shall not be considered a
Terminating Business Employee.  For purposes of this Section 6.04, an offer of
employment shall not be considered to be comparable unless it provides not less
than the same level of base compensation to the employee as he or she was
receiving from the Selling Entities immediately prior to the Closing Date and
similar type duties and responsibilities.





                                       21

         Purchaser shall reimburse the Selling Entities for the cost of all
severance benefits the Selling Entities pay to or provided for Terminating
Business Employees (pursuant to the Special Severance Program set forth in
Schedule 6.04 (other than payments with respect to unvested restricted stock of
Seller) or the Selling Entities' severance benefit program for their Canadian
employees and/or pursuant to applicable Canadian law), but not to exceed
$2,000,000.00 in the aggregate.

         Within 60 days following the Closing Date the Selling Entities will
invoice Purchaser for such cost with reasonable detail showing each Terminating
Business Employee with respect to whom such costs have been incurred.
Purchaser shall pay the amount of such invoice or invoices to the Selling
Entities within 10 business days of receipt in the same manner as an Adjustment
is payable to the Selling Entities pursuant to Section 3.03(c).

         Business Employees who receive and accept an offer of employment from
Purchaser are herein referred to as "PURCHASER'S NEW EMPLOYEES".  Purchaser
agrees that each of Purchaser's New Employees shall be entitled to such
employee benefits as are generally available to Purchaser's other employees in
its line of business similar to the Business.  For welfare benefit purposes
(other than vacation policies), Purchaser shall give each of Purchaser's New
Employees credit for his or her prior service with the Selling Entities and/or
their Affiliates and shall waive any waiting period for participation or
coverage in any welfare benefit plans or policies thereunder, except that
Purchaser shall not be required to waive any pre-existing medical condition
provision of such plan or policy.  In addition, Purchaser shall waive any
waiting period for participation and coverage in Purchaser's qualified
retirement plans by employees to the extent permissible under applicable law;
provided, however, that no credit shall be given for benefit accrual or vesting
purposes.  In connection with the transactions contemplated under this Section,
the parties agree to make all notifications required under the WARN Act.

         Notwithstanding anything to the contrary contained in this Section
6.04, in the event that any of Purchaser's New Employees are terminated by
Purchaser or any affiliate of Purchaser within a period of six (6) months from
the Closing Date, other than for cause, Purchaser shall pay, or cause to be
paid, to any such employee the equivalent of any amounts to which such
Purchaser's New Employee would have been entitled from Selling Entities
pursuant to the programs and laws described in this Section 6.04 had such
employee been a Terminating Business Employee (other than payments with respect
to unvested restricted stock of Seller).  Promptly following the expiration of
such six (6) month period, Purchaser will furnish to Seller a list of
Purchaser's New Employees who were terminated during such period and the
amounts of any severance benefits, if any, that were provided to such persons.

         6.05    NOTICE OF CHANGE.  To the extent of Purchaser's knowledge,
Purchaser shall give the Selling Entities prompt written notice of any material
changes in any of the information contained in the representation and
warranties made in Article IV or elsewhere in this Agreement or the Schedules
or Exhibits referred to herein which occur prior to Closing.

         6.06    HSR FILING.  Within five (5) business days after the execution

the Federal Trade Commission and the Antitrust Division of the United States
Department of Justice required under the Hart Scott Rodino Antitrust
Improvements Act of 1976 as amended and the rules and regulations promulgated
thereunder ("HSR ACT").

                                  ARTICLE VII
                          SELLING ENTITIES' COVENANTS

Business only in the ordinary course consistent with past practices, and the
Selling Entities shall use commercially reasonable efforts to preserve intact
the Business and the goodwill of their customers and suppliers. The Selling
Entities shall not take any action that will materially impair the Business or
Assets without the prior written consent of Purchaser, or take or fail to take
any action that would cause or permit the representations made in Article V
hereof to be inaccurate at the time of Closing or preclude the Selling Entities
from making such representations and warranties at the Closing, except to the

Selling Entities and notice thereof is promptly provided to Purchaser.

its authorized representatives, during normal business hours, full access to,
and make available for inspection, all of the Assets and the documents, records

information concerning the Business' customers and suppliers) which pertain to
such Assets and to the Business,  all for the sole purpose of permitting
Purchaser to become familiar with the Assets and the Business.  In that
connection, the Selling Entities shall cause their officers and employees and
the management personnel of the Business to cooperate fully with Purchaser's
reasonable requests.

         7.03    APPROVALS OF THIRD PARTIES.  As soon as practicable after the
execution of this Agreement, through the Closing and to the extent reasonably
required for the ninety (90) day period following Closing, the Selling Entities
will use all reasonable efforts to identify and secure all necessary approvals,
consents, permits and authorizations of third parties to the consummation of
the transactions contemplated by this Agreement, including consents necessary
to assign to Purchaser and have Purchaser assume all Assigned Contracts.  Such
efforts shall include, to the extent necessary, providing such third parties
with information about Purchaser.

         7.04    EMPLOYEE COMPENSATION AND BENEFIT MATTERS.  Except with
Purchaser's prior written consent or pursuant to contracts or plans in

will be made in the compensation or rate of compensation payable or to become
payable to the employees of the Business, no bonus, profit sharing, retirement,
insurance, death benefits, fringe benefit or other extraordinary or indirect
compensation shall accrue, be set aside





                                       23
<PAGE>   30
or be paid to, for or on behalf of any of such officers or employees other than
pursuant to the terms of the Selling Entities' Employee Benefit Plans as
presently constituted, and no agreement or plan other than those now in effect
shall be adopted or committed for.

         7.05    CONTRACTS.  Except with Purchaser's prior written consent, the
Selling Entities shall not waive any material right or cancel any material
contract or claim related to the Business.

         7.06    CHANGES IN PROPERTY AND EQUIPMENT; PAYMENTS OF LIABILITIES.
Except with Purchaser's prior written consent, the Selling Entities will not
(i) dispose of or commit to dispose of any compressors, except for dispositions
pursuant to a lease/purchase option contract listed in Schedule 5.04, (ii)
acquire or commit to acquire any compressors, except for acquisitions
consistent with commitments disclosed in Schedule 5.04, and (iii) acquire or
dispose of or commit to acquire or commit to dispose of any property and
equipment, other than compressors, except in the ordinary course of business
consistent with past practices.  The Selling Entities shall pay all liabilities
of the Selling Entities which relate to the Business as they become due.

         7.07    MORTGAGES, LIENS.  Except with Purchaser's prior written
consent, the Selling Entities will not enter into or assume any mortgage,
pledge, conditional sale or other title retention agreement relating to the
Assets, or voluntarily permit any lien, encumbrance or claim of any kind, other
than a Permitted Lien, to attach to any of the Assets, whether now owned or
hereafter acquired.

         7.08    NOTICE OF CHANGE.  The Selling Entities shall give Purchaser
prompt written notice of any material changes in any of the information
contained in the representations and warranties made in Article V or elsewhere
in this Agreement or the Schedules or Exhibits referred to herein which occur
prior to Closing.  In addition, Seller shall give Purchaser prompt written
notice of any discovery of any facts, conditions or information that would have
been included in the letter referred to in Section 5.23 had Seller been aware
of such facts, conditions or information as of the date of such letter.

         7.09    HSR FILING.  Within five (5) business days after the execution
of this Agreement, Seller shall file the notification and report form with the
Federal Trade Commission and the Antitrust Division of the United States
Department of Justice required under the HSR Act.

         7.10    EXCLUSIVITY. The Selling Entities shall not, and shall
instruct its Affiliates, directors, officers, key employees, financial advisors
and other representatives ("REPRESENTATIVES") not to, solicit, initiate,
encourage, discuss or respond to any proposal or offer, whether solicited or
unsolicited, from any person or entity other than Purchaser relating to any
disposition of the Business or the Assets.  The Selling Entities shall, and
shall cause its Representatives to, promptly inform Purchaser if any such
proposals or offers are received by it or them.  Without limiting the
generality of the foregoing, the Selling Entities shall, and shall cause its
Representatives to, cease all further discussions concerning a disposition of
the Business or Assets with all parties other than Purchaser that has
previously submitted a bid therefor.

<PAGE>   31
         7.11    PERMITS AND COOPERATION.  On or before the Closing, the
Selling Entities shall use their commercially reasonable efforts to cooperate
with Purchaser to arrange for an orderly transfer of all transferable
environmental, operating or other permits or licenses issued by governmental
authorities that relate to the Business (collectively, "PERMITS") and to make
any notifications of change in ownership required under such Permits or the
laws under which they were issued.  With respect to each nontransferable
permit, the Selling Entities shall cooperate fully with Purchaser in the
preparation and filing of an application with the appropriate governmental
authority for issuance of a replacement Permit in Purchaser's name.  Prior to
the Closing, the Selling Entities shall cooperate with Purchaser to arrange for
an orderly transition of the operation of the Business from the Selling
Entities to Purchaser, including taking such actions that minimize as much as
possible the length of time during which Purchaser will require services under
the Transition Services Agreement.

                                  ARTICLE VIII
                               OTHER REQUIREMENTS

         8.01    COLLECTION AND REPURCHASE OF ACCOUNTS RECEIVABLE.

                 (a)      COLLECTION OF THE SELLING ENTITIES' ACCOUNTS
RECEIVABLE.  On the Closing Date, Selling Entities shall deliver to Purchaser
the most recent listings available of invoices and the unpaid amount of each,
unbilled receivable amounts by customer (showing the contract, type of charge
and period covered), the invoices and amounts which comprise unearned revenue,
and other items making up the total accounts receivable of the Business.
Contemporaneously with the delivery of the Preliminary Closing Balance Sheet,
Selling Entities shall deliver updated listings of such items to Purchaser and
any such other information as Purchaser reasonably requests.  During the ninety
(90) day period following the Closing or until 30 days after the expiration of
the payment period for receivables with payment terms in excess of ninety (90)
days (the "COLLECTION PERIOD") and subject to the provisions of Section 8.01(c)
hereof, Purchaser shall use its commercially reasonable efforts (but in no
event shall Purchaser be obligated to file or perfect any liens or file or
prosecute any suit as part of its collection effort) to collect all invoice
amounts, notes and drafts receivable, and unbilled receivable amounts and other
receivable items in respect of the Business as of the Closing Date which are
included in the Final Closing Balance Sheet (the "CLOSING DATE RECEIVABLES")
(subject to the requirements of Section 8.01(c), such efforts to be
commercially reasonable if Purchaser has pursued the collection of such
receivables with the same degree of diligence as it pursues its other
receivables in the ordinary course of Purchaser's business).  Purchaser shall
prepare and send invoices to the customers relating to the unbilled receivables
as soon as practicable after the Closing.  Any payments received by Purchaser
from any person who is the account debtor on any of the Closing Date
Receivables (a "CUSTOMER") shall be applied as provided in Section 8.01(d).
Each of the Selling Entities shall promptly remit to Purchaser any payments
which it may receive in respect of any of the Closing Date Receivables.  Each
of the Selling Entities grants to Purchaser the authority, coupled with an
interest, to receive, endorse, cash, deposit, and receipt for any checks,
drafts, documents and instruments evidencing Closing Date Receivables which are
in the name of any of the Selling Entities.  Purchaser shall make and keep
detailed records of amounts collected in respect of the





                                       25
<PAGE>   32
Closing Date Receivables until such time as any Uncollected Receivables are
assigned to the Selling Entities pursuant to paragraph (b) below, and shall
make such records available for review by the Selling Entities when a statement
of Uncollected Receivables is delivered to Seller.

                 (b)      REPURCHASE OF ACCOUNTS RECEIVABLE.  Promptly
following the expiration of the Collection Period (but not earlier than ten
(10) days following determination of the Final Closing Balance Sheet),
Purchaser shall deliver to Seller one or more statements setting forth a list
of Closing Date Receivables (which has clearly identified thereon the names of
the customers, invoice numbers and uncollected amounts by invoice, together
with copies of all invoices and, if required, supporting documentation) that
were not collected during the Collection Period and the total of such
uncollected amounts.  Such statement shall not include the amount of any
balances owed on notes or accounts receivable that have been paid down in
accordance with their terms but the statement shall reflect as a deduction from
total uncollected amounts shown thereon (i) the total amount of any credit
balances included in the Closing Date Receivables not applied against invoices
for the same customer included in Closing Date Receivables, (ii) the amount of
the reserve for bad debts included in the Closing Date Balance Sheet and (iii)
the amount of unearned revenue included in the Closing Date Balance Sheet.  The
net amount set forth on the statement remaining, after giving effect to the
exclusions, if any, and deductions set forth in the preceding sentence, shall
be the net amount of receivables to be repurchased by the Seller (the
"UNCOLLECTED RECEIVABLES").  Within ten (10) business days following Seller's
receipt of such statement, the Selling Entities shall pay to Purchaser, by wire
transfer of immediately available funds,  to the account specified in Section
3.03(c) hereof, the amount of the Uncollected Receivables plus interest on such
amount at the rate of five percent (5%) per annum from the expiration of the
Collection Period to the date of payment by Purchaser.  Upon receipt of such
payment, Purchaser shall assign to Selling Entities, without recourse to the
Purchaser, the claims included in the Uncollected Receivables, including any
lien or other rights related thereto.

                 For purposes of this Section a separate statement of
Uncollected Receivables, prepared in accordance with the preceding paragraph of
this Section 8.01(b), except as set forth in this paragraph, shall be submitted
for accounts receivable originally billed to the Customer in Canadian dollars.
The uncollected amount of each accounts receivable invoice listed on this
statement will be the original Canadian dollar invoice amount less the amount
of Canadian dollar collections received and the Canadian dollar equivalent at
the date of receipt of any U.S. dollar collections received on such invoice.  A
separate payment shall be made by the Selling Entities to Purchaser for such
Uncollected Receivables in Canadian dollars.  The total amount of the reserve
for bad debts shall be deducted from the total amount of the uncollected U.S.
dollar accounts receivable invoices.

                 (c)      COLLECTION COOPERATION.  Purchaser shall keep the
Selling Entities' credit personnel reasonably informed with respect to
Purchaser's efforts to collect the Closing Date Receivables during the
Collection Period.  Selling Entities shall make available their credit
personnel to work with Purchaser during the Collection Period to assist in
resolving any disputes or questions concerning the Closing Date Receivables.

<PAGE>   33
                 (d)      ALLOCATION OF PAYMENTS RECEIVED AFTER CLOSING.
Notwithstanding any contrary directions received from a Customer, any payments
received by the Selling Entities or the Purchaser after the Closing Date from a
Customer that owed money to the Selling Entities for Closing Date Receivables
shall be promptly paid to the Selling Entities or the Purchaser, whichever of
them then owns such Closing Date Receivable (as provided in this Section 8.01)
until such Closing Date Receivable is satisfied in full; provided, however,
that if such Customer has a bona fide claim with respect to such Closing Date
Receivable that it does not owe the full amount thereof because of an act or
failure to act on the part of the Selling Entities prior to the Closing Date,
then, to the extent of the amount of such claim, Purchaser need not pay over to
the Selling Entities any such payment Purchaser receives from such Customer
after the Closing Date as payment for services provided by Purchaser to such
Customer.  Any funds to be paid over to the Selling Entities or Purchaser
pursuant to this Section 8.01(d) shall be paid in the same manner as specified
in Section 3.03(c).  The Selling Entities and Purchaser shall provide each
other with complete information concerning such payments in the same manner as
provided herein above in this Section 8.01.

                 (e)      REMEDY FOR UNCOLLECTED RECEIVABLES.  The provisions
of Article XI notwithstanding, the Selling Entities' indemnity obligation for
such Uncollected Receivables shall be satisfied by making the payment provided
for in Section 8.01(b) above, and no other remedy shall be available with
respect to such Uncollected Receivables or the representations set forth in
Section 5.16.

         8.02    CONDITION OF ASSETS; INTENDED USE.  AT THE CLOSING, PURCHASER
WILL HAVE CAREFULLY INSPECTED THE ASSETS AND KNOWINGLY AND VOLUNTARILY ACCEPTS
THE SAME "AS IS", AND "WHERE IS".  EXCEPT FOR THE REPRESENTATIONS AND
WARRANTIES GIVEN IN ARTICLE V, NO REPRESENTATION OR WARRANTY, EXPRESS OR
IMPLIED, HAS BEEN MADE BY OR ON BEHALF OF THE SELLING ENTITIES WITH RESPECT TO
THE PRESENT CONDITION OF THE ASSETS OR THE PRESENT OR FUTURE SUITABILITY
THEREOF FOR ANY INTENDED USE BY PURCHASER OTHER THAN AS SET FORTH IN SECTION
5.21 HEREOF.  Purchaser represents that it had an opportunity prior to
execution hereof to undertake such investigations of the Assets as it deemed
necessary or appropriate and to examine and review such records, documents,
reports and other information of the Selling Entities as it deemed relevant to
the consummation of this Agreement, except that no such investigation or
examination shall constitute a waiver by Purchaser of its right to rely on the
terms and conditions of this Agreement.

         The Selling Entities make no warranty, express or implied, regarding
the commercial suitability of the Owned Real Property or the Leased Real
Property for Purchaser's intended use.  Purchaser acknowledges that Purchaser's
knowledge of its intended commercial activity is superior to that of the
Selling Entities and consequently the Selling Entities cannot offer, and have
not offered, any warranty, express or implied, with regard to Purchaser's
intended commercial use of the Owned Real Property or the Leased Real Property.

<PAGE>   34
         8.03    TITLE REVIEW.  Seller shall furnish Purchaser surveys of the
Owned Real Property and standard form commitments for an owner's policy of
title insurance relating to the Owned Real Property in the amounts set forth in
Schedule 8.03 hereto.  The Title Commitments and legible copies of documents
creating exceptions contained in the Title Commitments and surveys supporting
the same as well as a Mortgage Certificate, Conveyance Certificate and Tax
Research Certificate relating to the Owned Real Property in the State of
Louisiana, shall be delivered to Purchaser no later than ten (10) business days
after execution of this Agreement.  Purchaser shall have ten (10) business days
from the date of delivery in which to raise title objections.  If title
objections are raised by Purchaser then Seller shall have fifteen (15) days
from the date such objections are raised to cure the same.  If objections are
not satisfied by the Closing Date, unless Purchaser elects to waive the
unsatisfied objections, the Purchase Price shall be reduced by the book value
of such Owned Real Property and such Owned Real Property shall become an
Excluded Asset.  At Closing, Seller shall furnish General Warranty Deeds in the
case of the Owned Real Property in the State of Texas and an Act of Sale in the
case of the Owned Real Property in the State of Louisiana, duly executed in
recordable form as per Exhibit B hereto.

         8.04    TITLE POLICIES AND SURVEYS.  The cost of the owner's policies
of title insurance and surveys relating to the Owned Real Property shall be
paid by Seller, provided that any premiums for insured values in excess of
$500,000 and $100,000, respectively, for the Mineral Wells, Texas property and
Lafayette, Louisiana property shall be for the account of Purchaser.

         8.05    TRANSITION SERVICES AGREEMENT.  Selling Entities and Purchaser
shall execute and deliver to each other the Transition Services Agreement
substantially in the form of Exhibit F.


                                   ARTICLE IX

Selling Entities an opinion of Victor I. Koock, Senior Vice President,
Co-General Counsel and Secretary of Purchaser, in form and substance as set
forth in Exhibit I attached hereto, addressed to Selling Entities and dated the
Closing Date.


                                   ARTICLE XI
                                INDEMNIFICATION

         11.01   SELLING ENTITIES' INDEMNITY.  Subject to the terms and
conditions of this Article XI and Section 8.01(e) of this Agreement, the Seller
hereby agrees to indemnify, defend and hold Purchaser and its officers,
directors, agents, attorneys, employees, subsidiaries, successors and assigns
and affiliates harmless from and against all losses, claims, obligations,
demands, assessments, penalties, liabilities, costs, damages, reasonable
attorneys' fees and expenses





                                       30

(collectively, "DAMAGES") asserted against or incurred by any or all of them by
reason of or resulting from:

                 (a)      Any claim relating to an Excluded Liability; and

                 (b)      A breach by the Selling Entities of any
representation, warranty or covenant contained in this Agreement or in any
agreement executed pursuant to this Agreement and not waived in writing by
Purchaser.

         11.02   PURCHASER'S INDEMNITY.  Subject to the terms and conditions of
this Article XI, Purchaser hereby agrees to indemnify, defend and hold the
Selling Entities and their officers, directors, agents, attorneys and
Affiliates harmless from and against all Damages asserted against or incurred
by any or all of them by reason of or resulting from:

                 (a)      Any claim relating to an Assumed Liability;

                 (b)      A breach by Purchaser of any representation, warranty
or covenant contained in this Agreement or in any agreement executed pursuant
to this Agreement and not waived in writing by the Selling Entities; and

                 (c)      Any and all liabilities, obligations and commitments
relating to the Business which arise out of, or relate to, events or
occurrences after the Closing or to any state of facts existing after the
Closing which had its inception after the Closing, including, without
limitation, any violation of any applicable federal, state, provincial or local
environmental laws or regulations.  In addition, the Purchaser agrees that to
the extent that, after the Closing, any of the Selling Entities incurs a
liability or is otherwise responsible for personal injury or property damage,
fines, penalties, remediation costs or other damages, including any liability
or responsibility under any environmental laws, then to the extent such loss is
based upon a condition or defect of the Assets that existed after the Closing
Date or relates to actions taken by the Purchaser in operating the Business
after the Closing Date, then Purchaser shall indemnify Selling Entities from
any such liability.

         11.03   BASKET.  Subject to the provisions of this Section 11.03, the
Seller shall not be required to indemnify Purchaser pursuant to Section 11.01
unless and until the aggregate amount of the Damages suffered or incurred by
Purchaser, other than those Damages described in Section 11.04 below, exceeds
$250,000 (the "BASKET").  In the event that the aggregate amount of such
Damages exceeds the Basket, the Seller shall indemnify Purchaser with respect
to the amount of such Damages but only to the extent that they are in excess of
the Basket.

         11.04   NON-BASKET ITEMS.   The following Damages shall not be
included in the calculation of the Basket.

                 (a)      Banker's/finder's fees for which the Selling Entities
are liable pursuant to Section 5.18; and





                                       31
<PAGE>   38
                 (b)      Any and all claims related to Excluded Liabilities.

         11.05   CAP.  The Selling Entities' liability for Damages shall not
exceed the Purchase Price; provided, however, that those Damages described in
Section 11.04 above shall not be subject to this Section 11.05.

         11.06   CONDITIONS OF INDEMNIFICATION.  The respective obligations and
liabilities of the Seller and Purchaser (the "INDEMNIFYING PARTY") to the other
(the "INDEMNIFIED PARTY") under Sections 11.01 and 11.02 hereof with respect to
claims resulting from the assertion of liability by third parties shall be
subject to the following terms and conditions:

                 (a)      Within twenty (20) days (or such earlier time as
might be required to avoid prejudicing the Indemnifying Party's position) after
receipt of notice of commencement of any action evidenced by service of process
or other legal pleading, or with reasonable promptness after the assertion in
writing of any claim by a third party, the Indemnified Party shall give the
Indemnifying Party written notice thereof together with a copy of such claim,
process or other legal pleading, and the Indemnifying Party shall have the
right to undertake the defense thereof by representatives of its own choosing
and at its own expense; provided, however, that the Indemnified Party may
participate in the defense with counsel of its own choice and at its own
expense.

                 (b)      In the event that the Indemnifying Party, by the
thirtieth (30th) day after receipt of notice of any such claim (or, if earlier,
by the tenth (10th) day preceding the day on which an answer or other pleading
must be served in order to prevent judgment by default in favor of the person
asserting such claim), does not elect to defend against such claim, the
Indemnified Party will (upon further notice to the Indemnifying Party) have the
right to undertake the defense, compromise or settlement of such claim on
behalf of and for the account and risk of the Indemnifying Party and at the
Indemnifying Party's expense, subject to the right of the Indemnifying Party to
assume the defense of such claim at any time prior to settlement, compromise or
final determination thereof upon reimbursement to the Indemnified Party of all
costs and expenses incurred by the Indemnified Party in conjunction with such
defense to that date.

                 (c)      Anything in this Section 11.06 to the contrary
notwithstanding, the Indemnifying Party shall not settle any claim without the
consent of the Indemnified Party unless such settlement involves only the
payment of money and the claimant provides to the Indemnified Party a release
from all liability in respect of such claim.  If the settlement of the claim
involves more than the payment of money, the Indemnifying Party shall not
settle the claim without the prior consent of the Indemnified Party, which
consent shall not be unreasonably withheld.

                 (d)      The Indemnified Party and the Indemnifying Party will
each cooperate with all reasonable requests of the other.

         11.07   REMEDIES EXCLUSIVE.  In the event of breach of this Agreement
or default hereunder, the remedies of the parties shall be limited to
indemnification as set forth in this Article XI and no right to rescission or
other common law right of action shall exist with respect to any breach of this
Agreement or default hereunder; provided, however, that Purchaser shall be
entitled to bring an action seeking an injunction if Purchaser has reason to
believe that the Selling Entities have violated or are about to violate the
provisions of Section 12.06.

                                  ARTICLE XII
                                 MISCELLANEOUS

         12.01   AMENDMENT.  This Agreement may be amended, modified or
supplemented only by an instrument in writing executed by a duly authorized
officer of each party to this Agreement.

         12.02   ASSIGNMENT.  The Selling Entities may not assign their rights
and obligations hereunder without the prior written consent of Purchaser, and
Purchaser may not assign its rights or obligations hereunder to any person
other than a direct or indirect wholly-owned subsidiary without the prior
written consent of the Selling Entities, which consent may be withheld for any
reason whatsoever, and provided further that any such assignment to a direct or
indirect wholly-owned subsidiary of Purchaser shall be conditioned upon
Purchaser executing and delivering to Selling Entities an unconditional
guarantee of the performance by such assignee of the obligations and duties
undertaken by Purchaser herein, all in such form and substance as may be
satisfactory to Selling Entities.

         12.03   NOTICE.  Any notice or communication must be in writing and
given by depositing the same in the United States mail, addressed to the party
to be notified, postage prepaid and registered or certified with return receipt
requested, or by delivering the same in person or by courier or by sending such

         12.04   PRE-CLOSING CONFIDENTIALITY.  Except for disclosures contained
in any filings made with the Securities and Exchange Commission or which are
otherwise required by law or the rules and regulations of any applicable stock
exchange, each party shall keep this Agreement and its terms confidential until
the Closing.  In the event that the transactions contemplated by this Agreement
are not consummated for any reason whatsoever, Purchaser and the Selling
Entities hereby (i) acknowledge and agree to be bound by all the terms and
conditions set forth in the Confidentiality Agreement and (ii) agree that,
notwithstanding the execution and delivery of the Agreement, the
Confidentiality Agreement will remain in full force and effect.

         Should the transactions contemplated hereby not be consummated,
nothing contained in this Section shall be construed to prohibit the parties
hereto from operating a business in competition with each other, provided they
do so without, in accordance with the Confidentiality Agreement, disclosing or
using confidential information of the other.

         12.05   POST-CLOSING CONFIDENTIALITY.  Each party shall not disclose
or use to compete with the other any confidential information pertaining to
such party which is obtained from such other party pursuant to this Agreement
or any document delivered in connection herewith or with the transactions
contemplated hereby, except as such use or disclosure may be required in the
course of performance hereof and such disclosure as may, in the opinion of such
party's counsel, be required by law.  After Closing, the Selling Entities shall
not (except at the request of





                                       34
<PAGE>   41
Purchaser) use or disclose to any third party any of the technical, financial,
operational or marketing information pertaining to the Business except after
and to the extent such information is or becomes generally available to the
public through no fault of the Selling Entities or as may be necessary in
connection with the Selling Entities' remaining or future business(es) or as
may, in the opinion of the Selling Entities' counsel, be required by law. The
parties shall take all reasonable efforts to cause their respective directors,
officers, employees and agents to observe the provisions of this Section 12.05.

         12.06   NO COMPETITION.  For a period of three years after the Closing
Date, neither the Seller nor any of its Affiliates shall engage directly or
indirectly in the business of renting natural gas compressors to third parties
in the United States or Canada; provided, however, that the foregoing
provisions of this Section 12.06 shall not prohibit the Seller or its
Affiliates from:

         (i) providing natural gas compression equipment or services to third
parties by means other than rental or lease,

         (ii)  providing natural gas compression equipment or services as part
of a larger business undertaking for a third party or parties to provide them
with other oil field services and products or engineering and construction
services pursuant to which natural gas compression is an integral part,

         (iii) entering into any business combination, consolidation, merger or
other type of business combination or acquisition transaction with any other
party or parties who owns and/or operates a business that rents compressors,
and thereafter continuing to own and/or operate such business, provided that at
the time of such transaction less than forty-five percent (45%) of the
consolidated revenues of such other party or parties are generated by such
compressor rental business, or

         (iv)  making an investment in the securities of another company which
conducts such a compressor rental business provided such investment constitutes
less than 10% of the total equity of such other company and thereafter
continuing to hold such investment.

         12.07   ENTIRE AGREEMENT.  This Agreement, the Schedules and the
Exhibits hereto and that certain environmental disclosure letter to Purchaser
dated October 17, 1994 supersede all prior agreements and understandings
relating to the subject matter hereof, except that the obligations of any party
under any agreement executed pursuant to this Agreement shall not be affected
by this Section.

         12.08   COSTS, EXPENSES AND LEGAL FEES.  Whether or not the
transactions contemplated hereby are consummated, each party hereto shall bear
its own costs and expenses (including, without limitation, attorneys',
broker's, agent's, investment banking and finder's fees), except that each
party hereto agrees to pay the costs and expenses, including reasonable
attorneys' fees, incurred by the other party in successfully (a) enforcing any
of the terms of this Agreement, or





                                       35
<PAGE>   42
(b) proving that the other party breached any of the terms of this Agreement in
any material respect.

         12.09   SEVERABILITY.  If any provision of this Agreement is held to
be illegal, invalid or unenforceable, such provision shall be fully severable
and this Agreement shall be construed and enforced as if such illegal, invalid
or unenforceable provision never comprised a part hereof, and the remaining
provisions hereof shall remain in full force and effect and shall not be
affected by the illegal, invalid or unenforceable provision or by its severance
herefrom.

         12.10   WAIVER.  All of the original rights and powers of either party
hereunder shall remain in force notwithstanding any neglect, forbearance or
delay in enforcement thereof and neither party shall be deemed to have waived
any of its rights or any provision of this Agreement or any notice given
hereunder unless such waiver is in a writing signed by an officer of the
waiving party.  No such waiver by either party of any breach by the other party
of this Agreement shall be deemed a waiver of any continuing, future or
recurring breach.

         12.11   GOVERNING LAW.  THIS AGREEMENT AND THE RIGHTS AND OBLIGATIONS
OF THE PARTIES HERETO SHALL BE GOVERNED, CONSTRUED AND ENFORCED IN ACCORDANCE
WITH THE LAWS OF THE STATE OF DELAWARE, WITHOUT REGARD TO THE CHOICE OF LAW
PROVISIONS THEREOF OR SUCH PROVISIONS OF ANY OTHER JURISDICTION.

         12.12   CAPTIONS.  The captions in this Agreement are for convenience
of reference only and shall not limit or otherwise affect any of the terms or
provisions hereof.

         12.13   COUNTERPARTS.  This Agreement may be executed in counterparts,
each of which shall be deemed an original, and all of which together shall
constitute one and the same instrument.

         12.14   COOPERATION.  Subject to the terms and conditions herein
provided, each of the parties hereto agrees to use all reasonable efforts to
take, or cause to be taken, all actions and to do, or to cause to be done, all
things necessary, proper or advisable to consummate and to make effective as
promptly as practicable the transactions contemplated by this Agreement,
including without limitation using all reasonable efforts to obtain all
necessary waivers, consents and approvals and to effect all necessary
registrations and filings.  Further, the Parties agree to cooperate with each
other in the preparation and filing of any and all tax returns relating to the
Business or the sale thereof and will take such other and further actions
following the Closing as may be necessary or desirable to carry out the
purposes of this Agreement.  The Selling Entities hereby authorize Purchaser
after the Closing to receive and, subject to the following sentence, open all
mail and other communications addressed to the Selling Entities received by
Purchaser.  Purchaser agrees (i) to promptly forward to Seller and to hold in
confidence any such mail or other communications that do not relate to the
Business and (ii) to forward to Seller unopened any such mail or communications
addressed to Seller's executive offices or corporate headquarters.  To the
extent Purchaser reasonably requires access to any books or records relating





                                       36
<PAGE>   43
in whole or in part to the Business or Assets that are not conveyed under
Section 2.01(a)(6), the Selling Entities shall cooperate in granting Purchaser
with access to all documents, records and information reasonably required by
Purchaser.

         12.15   BULK SALES COMPLIANCE.  The parties hereto waive compliance
with all applicable provisions, if any, of the bulk sales laws of the states in
which the Assets are located, or similar laws of any jurisdiction.

         12.16   SURVIVAL OF REPRESENTATIONS, WARRANTIES, COVENANTS AND
AGREEMENTS.  Except as otherwise provided in this Section 12.16 or elsewhere in
this Agreement, all representations, warranties, covenants and agreements of
the parties contained in this Agreement or in any Schedule or Exhibit and any
related agreements shall survive the execution and delivery of this Agreement
and consummation of the transactions provided for in this Agreement and any
related agreements, notwithstanding any investigation made by or on behalf of
the parties.  The representations and warranties contained in Article IV and
Article V of this Agreement shall terminate two years following the Closing
Date, except for the representations, warranties, covenants and agreements
contained in Sections 4.02, 5.02, 5.03 and 5.05 which shall have no termination
date.  No representation, warranty or covenant shall merge into the deeds, Act
of Sale, bills of sale, assignments, documents, agreements and instruments to
be delivered at Closing.

         12.17   RISK OF LOSS.  The risk of any loss, damage, impairment,
confiscation or condemnation of Selling Entities' Assets, or any part thereof,
shall be upon the Selling Entities at all times prior to the Closing.  In any
such event, the proceeds of, or any claim for any loss payable under any
insurance policy, judgment or award with respect thereto shall be payable to
Selling Entities.  In such event, Selling Entities shall either:  (i) repair,
replace or restore any such property as soon as possible after its loss,
impairment, confiscation or condemnation; or (ii) if insurance proceeds are
sufficient to repair, replace or restore the property, pay such proceeds to
Purchaser on the Closing Date or as soon thereafter as possible; provided that
in the event of damage that would have a material adverse effect on the
Business or the Assets taken as a whole, either party may, by written notice
made pursuant to Section 12.03, terminate this Agreement.  To the extent any
such proceeds shall be payable after the Closing, the Selling Entities shall
cooperate with Purchaser in pursuing these claims.


                                  ARTICLE XIII
                                  TERMINATION

restrains or enjoins in any material respect the consummation of the
transaction contemplated hereby;

                 (e)      by written notice given by the Selling Entities at
such time as any of the conditions to the obligations of the Selling Entities
provided in Article X cannot be satisfied and will not be waived by the Selling
Entities; or

                 (f)      by written notice given by the Purchaser at such time
as any of the conditions to the obligations of the Purchaser provided in
Article IX cannot be satisfied and will not be waived by the Purchaser.

         13.02   EFFECT OF TERMINATION.  If this Agreement is terminated under
Section 13.01 herein, neither Purchaser nor the Selling Entities nor any of
their respective stockholders, directors, officers or employees shall have any
