                           OEC COMPRESSION CORPORATION
                                  ANNUAL REPORT
                      FOR THE YEAR ENDED DECEMBER 31, 1999
                                     PART I

ITEMS 1. AND 2.  DESCRIPTION OF BUSINESS AND PROPERTIES

GENERAL

         OEC Compression Corporation, formerly Equity Compression Services
Corporation, formerly Hawkins Energy Corporation (the "Company") is engaged
in the leasing, contract management, outsourcing, remanufacturing and direct
sale of gas compression equipment to operators of producing natural gas wells
and gas gathering systems. Its principal geographical operating areas lie
within the states of Alabama, Mississippi, Louisiana, Oklahoma, Arkansas,
Kansas, New Mexico and Texas.

         The Company was incorporated as Hawkins Energy Corporation in the
state of Oklahoma in June 1989 for the purpose of consolidating the
businesses and assets of Equity Compressors, Inc. ("Equity Compressors") and
ten Hawkins Exploration oil and gas limited partnerships (the "Hawkins
Limited Partnerships"). To effect the consolidation, the Company extended an
exchange offer to the stockholders of Equity Compressors and the partners of
the Hawkins Limited Partnerships. Following approval by a majority in
interest of the limited partners in each of the Hawkins Limited Partnerships,
the Company acquired the assets and assumed the liabilities of the Hawkins
Limited Partnerships and acquired the stock of Equity Compressors, all in
exchange for common stock of the Company, and commenced operations on
December 29, 1989.

         The Company acquired Equity Compressors when its sole business was
the leasing of gas compression equipment to operators. Equity Compressors
broadened its scope of operations through its acquisition in April 1990 of a
compressor remanufacturing and service business. The business of the acquired
company centered around the acquisition, remanufacture and sale of existing
gas compressor units. By May 1990, this business was fully integrated into
Equity Compressors.

         In June 1993, the Company acquired Mid-South Compressors, Inc., a
privately held gas compression company ("Mid-South"). Mid-South leased
compression equipment throughout the gas-producing regions of Mississippi,
Alabama and Northern Louisiana. The transaction involved the issuance of
approximately 5.4 million shares of Company common stock and the payment of
$1.4 million in cash to Mid-South. The Company financed the cash portion of
the acquisition through additional borrowings.

         In July 1993, the Company acquired all the outstanding shares of
common stock of Owens Compression Service, Inc. ("Owens"), a privately held
company that provided gas compression services primarily in East Texas and
North Louisiana in exchange for cash consideration of $42,000 and
approximately 3.2 million shares of Company common stock.

         During March 1995, the Boards of Directors of Equity Compressors,
Mid-South and Owens each approved the formal merger of Mid-South and Owens
with and into Equity Compressors. The companies merged their operations under
the Equity Compressors name as of January 1, 1995. The businesses of Equity
Compressors included leasing, direct sales and remanufacturing services of
various types of gas compression equipment.

         During December 1996, the shareholders of the Company approved an
increase in the number of authorized shares of common stock enabling the
Company to sell 8 million shares of common stock and 8 million contingent
warrants for a total cash consideration of $4.4 million to HACL, Ltd., a
Dallas-based investment group. Additionally, shareholders voted to change the
name of the Company to Equity Compression Services Corporation.

         On August 6, 1997, the Company acquired 100% of the common stock of
Ouachita Energy Corporation ("Ouachita") and the majority of the assets of
Ouachita Compression Group, LLC and Ouachita Energy Partners, LTD. Under the
terms of the acquisition agreements that were closed effective July 31, 1997,
the Company issued to the shareholders 7.6 million shares of the Company's
common stock and paid approximately $24 million in cash and assumption of
debt.

         On October 30, 1997, the Company, through its wholly owned
subsidiary, Sunterra Energy Corporation, entered into a venture with Prize
Petroleum, L.L.C. ("Prize") of Tulsa, Oklahoma, to form Sunterra Petroleum
Company, L.L.C. ("Sunterra L.L.C."). Sunterra L.L.C. was initially
capitalized with oil and gas properties and cash commitments with a value in
excess of $9 million.

         On December 31, 1997, the Company closed its shop facilities in
Oklahoma City, Oklahoma, Kilgore, Texas, and Columbia, Mississippi. The
acquisition of Ouachita enabled the Company to consolidate the facilities
operations into one state-of-the-art facility located in West Monroe,
Louisiana. Although significant costs were incurred as a result of the
closing of these facilities in the fourth quarter of 1997, the consolidation
of the shop facilities allowed the Company greater control over product

                                       3
<PAGE>
engineering and design, better quality equipment, more reliable service and
increased control over expenses at the facility level.

         On March 6, 1998, the Company merged Equity Compressors into
Ouachita. At December 31, 1999, the combined compressor fleet had 854 gas
compression units with a total of approximately 229,000 horsepower.

         In March 1998, the number of authorized shares of common stock was
increased and the name of the Company changed to OEC Compression Corporation.

         At December 31, 1998, Sunterra L.L.C.'s oil and gas properties were
estimated to have proved reserves of 12,720,000 thousand cubic feet ("mcf")
of natural gas and 163,000 barrels of oil. Natural gas reserves constituted
approximately 93% of the Company's reserve base on a "gas equivalent" basis
(converting each barrel of oil to six mcf of natural gas).

         On July 2, 1999, Sunterra sold 100% of its interest in Sunterra
L.L.C. to Prize. Sunterra received $1 million in cash and the Will-O-Mills
gas treating plant located in southwest Texas. The Will-O-Mills gas treating
plant is a 300 gpm amine plant, which extracts carbon dioxide, and minor
amounts of hydrogen sulfide from natural gas flowed to the plant by area
producers under long-term treating contracts. The Sunterra L.L.C sale
effectively removed the Company from the oil and gas production business.

         The primary business plan of the Company is growth within the
compression service sector of the natural gas industry. The Company plans to
extend its activities in the compression service sector by expanding its
customer base and its business with existing customers by providing the
highest quality compression services. Additionally, the Company will pursue
the purchase of customer owned compressors as well as the purchase of
competitors.

         The Company had 118 employees at year-end 1999. Its principal
executive offices are maintained at 2501 Cedar Springs Road, Suite 600,
Dallas, Texas 75201. The Company's telephone number is (214) 953-9560.

GAS COMPRESSION OPERATIONS

         GENERAL. The Company conducts its compressor operations through
Ouachita Energy Corporation, its wholly owned subsidiary located in West
Monroe, Louisiana.

         The age of a gas well usually affects its need for compression. A
gas well has a natural flowing pressure which may or may not be adequate to
overcome the pipeline pressure at the point where the gas is introduced into
a gathering system or transmission pipeline. If the flowing pressure of the
gas is not adequate to overcome the pipeline pressure, it is not physically
possible to produce or transport the gas without the aid of compression. Gas
compression is used to overcome this problem by boosting the flowing pressure
of the gas. Theoretically, all gas wells will eventually need compression to
boost natural well flowing pressure to exceed pipeline pressure.
Historically, gas compressors have generally been purchased and operated by
gas producers and gas transporters. However, over the last several years,
these same groups have also used equipment leasing and contract compression
services as an accepted means of providing for their gas compression needs.

         EQUIPMENT LEASING AND CONTRACT COMPRESSION SERVICES. At year-end
1999, the Company's service fleet included 854 compressors located in
Alabama, Arkansas, Kansas, Louisiana, Mississippi, Oklahoma, New Mexico and
Texas. These compressors average 268 horsepower in size and their cost as a
new unit of similar size averages about $230,000. The Company's rental fleet
is comprised mostly of used, remanufactured equipment, which was acquired at
a substantial discount to the cost of comparable new compressor units. The
fleet includes engines and compressors of various manufacturers.

         Prior to the Ouachita acquisition in the third quarter of fiscal
year 1997, the Company's core business was compression
rental-with-maintenance to natural gas producers, processors and pipelines.
With the Ouachita acquisition, the Company commenced providing full contract
compression services, which is the complete "outsourcing" of a client's
compression operations to the Company.

         The size and configuration of each compressor varies depending on
the particular application for which it is utilized. Consideration is given
to the differential between the wellhead and pipeline flowing pressures and
the volumes of gas delivered from the wellhead.

         The following table sets forth certain data concerning the Company's
activity in the acquisition and leasing of compressors:

</TABLE>

         LEASE/CONTRACT COMPRESSION TERMS. Generally, the Company's
compressors are leased for contract compression services, which are provided
to well operators under written agreements for periods ranging from
month-to-month to six years. These contracts are sometimes renewed at the end
of the specified term at which time the rentals and other terms may be
renegotiated. The competitive marketplace determines the rental/contract
rates used in new contracts and in renewals of existing contracts. Once the
minimum term has expired, the equipment continues on a month-to-month basis,
with either party having the right to terminate the contract by giving a
30-day written notice. The majority of the deployed compressors at December
31, 1999 were leased on a month-to-month basis.

         Under the typical rental-with-maintenance lease, the lessee pays the
costs of transporting the compressor to the well site, installation, all fuel
and other operating costs. The compressors are operated on a daily basis by
the employees of the lessee. The Company maintains service departments which
employ skilled compressor mechanics who service and maintain compression
equipment. Under the most common type of lease, the lessee pays a flat fee
for monthly compression inclusive of service, equipment rental, lubricants
and all parts and maintenance. Under the typical contract compression service
contract, the Company provides the customer with both the compression
equipment and operates that equipment for the customer. The Company's
personnel are responsible for both day-to-day operation and maintenance of
the provided compression equipment for a monthly service fee. Revenues
associated with contracts for rental-with-maintenance and contract
compression services are recognized on the first day of the month in which
the service is provided.

         REMANUFACTURING SERVICES. Remanufacturing services involve the
overhaul and rework of equipment owned by third parties. These services are
performed under contract with numerous customers, including gas gathering and
transmission companies, major oil companies, large independents and small
producers to overhaul and rework their gas compression equipment. Generally,
the Company prepares a description of the work to be conducted and the parts
to be provided. An estimate or a fixed bid of the costs to be charged to the
customer for the overhaul work accompanies this description. In the event
additional labor or parts are required once the work is in process, the owner
of the unit is contacted regarding the work and additional charges are then
agreed on. Overhaul work is normally guaranteed for a period of 90 days.

         COMPRESSOR SALES. The Company is also involved in the direct sales
of remanufactured gas compression equipment. The Company acquires, rebuilds
and sells previously owned gas compressor units to gas producers and
transporters. The Company maintains an inventory of compression parts and
equipment at its facility in West Monroe, Louisiana. The Company is able to
sell its remanufactured equipment at a discount to the cost of comparable new
equipment, and in most cases is able to customize and complete a compressor
unit for a customer in substantially less time than the same customer could
acquire the equipment new from the original manufacturer. The Company, via
its field mechanics, is responsible for the service and maintenance of its
direct sales units during their 90-day warranty period.

         MARKET AND CUSTOMERS. The Company's customer base consists of over
180 U.S. companies engaged in all aspects of the oil and gas industry
including major integrated oil and gas companies, large and small independent
producers, natural gas processors, gatherers and pipelines. No individual
customer accounted for more than 10% of the Company's consolidated revenues
during 1998 or 1999.

         COMPETITION. The natural gas compression services business is highly
competitive. Overall, the Company faces competition from companies with
considerably greater financial resources as well as from several smaller
companies on a more regional basis. The Company believes it is the sixth
largest compressor services company, defined by total horsepower, in the
onshore domestic markets in which it operates.

                                       5

<PAGE>

         Increased size and geographic breadth offer compressor services
companies' significant advantages. Supporting staff costs (i.e. sales,
accounting, engineering) do not rise proportionately with increases in the
number of deployed compressors. As a result, companies the size of the
Company or larger benefit from lower overall operating costs than competing
smaller companies.

         The Company believes it competes effectively on the basis of price
as well as the quality and reliability of service in the geographic markets
it operates (Alabama, Mississippi, Louisiana, Arkansas, Oklahoma, Kansas,
Texas and New Mexico).

COMPLIANCE WITH ENVIRONMENTAL LAWS

         The design and operation of gas compressors is subject to certain
federal and state environmental laws and regulations which, directly or
indirectly, relate to the discharge of materials into the environment.
Complete compliance with all of such laws and regulations may affect the
Company's operations and costs as a result of their effect on the design,
condition and operation of its gas compressors or its costs of repairing or
remanufacturing them. Under most of the leases for the gas compressors,
responsibility for compliance with the majority of these laws and regulations
is placed on the lessee. However, there can be no assurance that the Company
would not be liable for any penalties or fines that may be imposed as a
result of any material noncompliance. It is not anticipated that the Company
will be required in the near future to expend amounts that are material in
the aggregate to the Company's overall operations by reason of such laws and
regulations.

NATURAL GAS AND OIL OPERATIONS

         GENERAL. The Company acquired interests in natural gas and oil
properties by acquiring the assets and assuming the liabilities of ten oil
and gas limited partnerships on December 29, 1989, as a result of the
exchange offer.

         On July 2, 1999, Sunterra sold 100% of its interest in Sunterra
L.L.C. to the Prize Petroleum. Sunterra received $1 million in cash and a
100% ownership interest in the Will-O-Mills gas treating plant located in
southwest Texas. The Will-O-Mills gas treating plant is a 300 gpm amine
plant, which extracts carbon dioxide, and minor amounts of hydrogen sulfide
from natural gas flowed to the plant by area producers under long term
treating contracts. The Sunterra L.L.C sale effectively removed the Company
from the oil and gas production business.

         SIGNIFICANT PROPERTIES. At December 31, 1998, the Company owned oil
and gas interests in 152 producing wells, undrilled leasehold interests and
related assets located in Arkansas, Kansas, Oklahoma and Texas. Exploration
and development efforts have been concentrated in the Anadarko and Arkoma
Basins located in the states listed above. As of December 31, 1999, the
Company owned no producing wells.

         DRILLING ACTIVITIES. During the periods indicated, the Company
participated in the drilling of the following development wells:

         MARKET FOR OIL AND GAS. The market for oil and gas production
depends upon a number of factors, including the availability of other
domestic production, crude oil imports, the proximity and size of oil and gas
pipelines, the marketing of competitive fuels and general fluctuations in the
supply and demand for oil and gas. For the past several years, there has
existed a surplus of imported oil and domestic natural gas. In addition, such
oversupplies may cause delays in marketing the natural gas from producing
wells.

         While certain of the Company's natural gas production is sold at the
wellhead to intrastate and interstate pipelines under contracts with terms
ranging from one to twenty years, most of its gas production is sold on the
"spot market" under commitments which generally extend for only 30 days. All
of the Company's long-term contracts contain provisions for readjustment of
price, termination and other terms customary in the industry. Certain of
these contracts contain "market out" and price adjustment provisions which
could allow the purchaser to cancel the contract or purchase the gas produced
at a substantially lower price. Likewise, if prices increase, the Company can
cancel the contract or require the gas produced to be purchased at the higher
prices.

         The Company does not believe that the loss of any of its oil
purchasers, if not replaced, would have a material adverse effect on its
operations. The loss of a gas purchaser could result in contracts being
executed for sales with prices less than those previously

                                       6

in effect or in prolonged production delays. The loss or termination of
several gas purchase agreements or purchasers could, if not replaced,
adversely affect the Company's financial condition. The marketing of oil and
gas by the Company can be affected by a number of factors which are beyond
its control, the exact effects of which cannot be accurately predicted.

REGULATIONS

          The oil and gas industry is extensively regulated by federal, state
and local authorities. Legislation affecting the oil and gas industry is
under constant review for amendment or expansion. Numerous departments and
agencies, both federal and state, have issued rules and regulations binding
on the oil and gas industry and its individual members, some of which carry
substantial penalties for the failure to comply. The regulatory burden on the
oil and gas industry increases its cost of doing business and, consequently,
affects its profitability. Inasmuch as such laws and regulations are
frequently amended or reinterpreted, the Company is unable to predict the
future cost or impact of complying with such regulations.

EMPLOYEES

          At December 31, 1999, the Company had 118 full-time employees. The
Company has 111 employees in its gas compression operations and 7 employees
in its general corporate area. None of these employees are represented by a
union or labor organization. The Company considers its relations with these
employees to be satisfactory.

PROPERTIES AND FACILITIES

          The Company owns its shop facilities in West Monroe, Louisiana. The
main building contains approximately 35,000 square feet, the majority of that
space designed for the re-manufacturing and overhauling of the Company's
compression fleet with the balance being office space. The property includes
approximately eight acres of land.

          The Company owns 12 acres of land, office facilities and a warehouse
in Bridgeport, Texas.

         The Company leases its executive office space in Dallas, which consists
of approximately 4,500 square feet.

ITEM 7.   MANAGEMENT'S DISCUSSION AND ANALYSIS OF
          FINANCIAL CONDITION AND RESULTS OF OPERATIONS

RESULTS OF OPERATIONS
1999 VERSUS 1998

          Compression and gas treating service fees increased $228,000 or 1%
from 1998. The Company did not experience the level of revenue growth in 1999
that it achieved in 1998. The reasons were twofold: the Company discontinued
compression services in February 1999, for a client which represented
approximately 6% of its deployed compression horsepower. Additionally, the
Company believes the entire compression services industry experienced a
general slowdown in compression demand growth apparently caused by the
precipitous fall in 1998 of natural gas prices which subsequently impacted the
industry's client base's capital budgets for 1999. The Company believes
rebound in the natural gas price in 1999 has refueled compression demand
growth in the last half of the year. From July through December 1999, the
Company's deployed compression horsepower grew 7%. July was the Company's
lowest deployment level for all of 1999. Compression operating costs decreased
$212,000 (3%) from 1998 due to continued focus on cost controls in the field
operations.

          Compressor sales and remanufacturing revenue fell $303,000 (43%)
from 1998. The decrease reflects the Company's continued focus on the higher
margin contract compression services over third-party equipment sales. The
associated compressor sales and remanufacturing direct costs fell $398,000
(59%) from 1998 due to increased focus on job costing.

          Oil and gas sales decreased $1 million from 1998 due to the sale of
the oil and gas operations in July 1999. The Company held 100% of its oil and
gas producing interest in Sunterra. which was majority owned by the Company
but operated by the minority owner Prize. On July 2, 1999, the Company sold
100% of its interest in Sunterra to Prize for $1 million in cash and 100%
interest in the Will-O-Mills gas treating plant, a 300GPM Amine Plant in West
Texas. The Company entered into the transaction to replace a depleting asset
with a redeployable asset with a similar operating profile to gas compression.
The Company reported a $421,000 gain on the sale. Oil and gas operating costs
fell $258,000 from 1998 due to the previously described sale.

          Compressor depreciation increased $200,000 (4%) from 1998. The
increase was due to 1) continued capital investment to upgrade the fleet and
2) a substantial turnover of compression equipment on existing compression
jobs in the March - July 1999 period. The Company believes the latter was the
result of an industrywide turnover of equipment. The industry's collective
client base, predominantly exploration and production companies, coming off a
poor gas price year in 1998 and looking for cost and revenue efficiencies,
made a major effort to "right size" their existing rental compression to the
current application. The result was a major turnover of equipment on
applications. The turnover generated a higher than normal level of capital
investment in refurbishing idle equipment to replace the returning over or
under sized equipment. Oil and gas depletion and depreciation fell $270,000
due to the July Sunterra sale described above. Intangibles amortization
increased $233,000 from 1998 due to the amortization of the balance of the
non-compete and non-solicitation agreements between the Company and two former
executive officers of the Company who resigned in December 1998.

          General and administrative expense fell $375,000 (9%) from 1998. The
Company's continued focus on cost controls was the principal reason for the
cost reduction. Included in 1999 general and administrative costs is
approximately $300,000 of predominately legal and professional costs
surrounding the activities of two special committees of the Board of Directors
established to review and evaluate certain merger and acquisition activities
during the year.

          Cashflow, defined as earnings before interest, taxes, depreciation,
and amortization ("EBITDA") rose $159,000 from 1998 to $11 million.

          In November 1999, the Company sold and leased back virtually all of
its owned vehicles to a subsidiary of GE Capital. The transaction generated a
net loss on sale of $169,000.

          Interest expense increased $692,000 from 1998 due to substantial
fleet growth in 1998 that was predominantly debt financed. That growth was
being generated over all of 1998, the increased interest expense is fully
realized in 1999. The July Sunterra sale eliminated minority interest expense
beyond that point. As a result, this expense item fell $58,000.

                                       10
<PAGE>

          The Company reported a pre-tax loss of $293,000 for the 1999 fiscal
year versus $129,000 pre-tax profit for 1998. However, an income tax benefit
of $414,000 created after-tax net income of $121,000 versus 1998 net earnings
of $12,000.

          Capital expenditures on the compressor fleet totaled $11.1 million
in 1999 versus $21.1 million in 1998. The acquisition of compression equipment
through purchase / leaseback transactions accounted for $1.5 million of the
1999 fleet capital expenditures. Roughly 85% of the aggregate purchase /
leaseback investment occurred in December 1999 and, therefore, had little
impact on 1999 earnings. Field capital expenditures, to sustain the value and
operational performance of the operating fleet, totaled $3.1 million. Roughly
90% of the remaining $6.5 million capital investment represented investment in
the existing fleet through shop operations to sustain and enhance the value of
the existing fleet as it was deployed on new jobs. The balance represented
purchases of equipment in the open market to fill job applications, which
could not be matched with equipment in the existing fleet. The Company
believes that the shop CAPEX levels on the existing fleet were inflated in
1999 due to the substantial turnover of equipment on existing jobs in the
spring-through-summer period of 1999. As previously discussed, the Company
believes the entire compression industry experienced a substantial turnover of
equipment during the defined period as the industry's collective client base,
mostly independent exploration and production companies, attempted to "right
size" their leased compression to gain cost and production efficiencies in the
face of 1998 gas and oil price driven budget constraints. The immediate impact
of the action is increased capital investment for little if any additional
revenue. However, there are longer-term benefits in the form of decreased
future capital investment.

RESULTS OF OPERATIONS
1998 VERSUS 1997

          In 1998, compressor rental revenues increased $10.8 million or 87%
from 1997 due to growth associated with the acquisition of working compression
equipment and internal growth. Revenues from compressor sales and
remanufacturing services decreased $271,000 or 28% in 1998 from 1997. This
decrease reflects the concentration of shop labor on maintaining and enhancing
the rental/contract compressor fleet. Gross profit from compressor sales and
remanufacturing services decreased to $36,000 in 1998 from $38,000 in 1997 due
to the recognition of approximately $72,000 of expenses related to third-party
service work classified as inventory at December 31, 1997, was determined to
be unrecoverable in 1998.

          Compressor operating costs of $9.7 million incurred on rental and
contract units increased 92% as a result of the increased horsepower on lease.
Compressor operating cost growth exceeds revenue growth principally due to
incremental costs associated with installing additional equipment as well as
start-up costs in new operating regions.

          Revenues from oil and gas sales decreased $276,000 or 10% in 1998
from 1997 primarily due to a 54% decrease in the volume of oil sold and a
decrease in the average prices received by the Company. This decrease in oil
volume is the result of the sale of a secondary oil recovery project located
in Texas. The average price per Bbl decreased from $19.35 in 1997 to $13.51 in
1998. The volume of natural gas sold by the Company increased 60% during 1998
when compared to 1997 due to the successful drilling of two development wells
and the properties contributed by Prize. The average price of natural gas
received by the Company decreased 20% from $2.65 per Mcf in 1997 to $2.11 per
Mcf in 1998.

          Oil and gas operating costs for 1998 are 9% lower than the same
period in 1997 resulting from the sale of the secondary oil recovery project.

          Depletion, depreciation and amortization of the composite cost of
evaluated oil and gas properties is computed on the units-of-production method
based on estimated proved reserves. The 1998 expense related to oil and gas
properties is 47% higher when compared to 1997 due to the higher volumes of
gas produced. Depreciation of the compressor fleet increased 50% from 1997 due
to the growth of the compressor fleet through acquisition and additions to the
existing fleet. Associated with its acquisition of Ouachita, the Company
changed its estimate of useful lives for certain of its compressor equipment
to 20 years with capitalized overhauls on compressor rental equipment
depreciated over five years. The effect of these changes decreased the 1997
loss from operations, net loss and loss per share (dilutive) by $265,000,
$165,000, and $.01, respectively.

          General and administrative costs increased 5% to $4,299,000 when
compared to 1997. The increase relates to expenses associated with the
Company's increased level of operations. However, general and administrative
expenses as a percentage of total revenues was 16% as compared to 26% for the
same period ended December 31, 1997.

          Interest expense increased to $4,536,000 in 1998 from $1,884,000 in
1997 due to increased debt balances to finance the acquisition of Ouachita,
and additional borrowings to finance the growth of the compressor fleet.
During 1998, the Company has

                                      11

<PAGE>

purchased a number of idle compressor units as well as compressor parts due to
a favorable market price for the equipment with expectation of deploying that
equipment for future compression service contracts. The natural lag between
purchase and contract revenue generation has contributed to the increase in
interest expense.

          Unamortized debt issue cost of approximately $70,000 associated with
the prior credit facility was expensed in the first quarter of 1998 as an
extraordinary item.

CAPITAL RESOURCES AND LIQUIDITY

          On March 30, 1998, the Company replaced its previously existing $20
million senior bank credit facility with a new senior bank credit facility.
The initial maximum commitment was $40 million, which remains expandable to
$60 million with the future addition of other participating financial
institutions. In March 2000, the Company's senior lender agreed to extend the
revolving period until July 2001. The facility as amended is a borrowing base
revolver effective through July 2001, due in full on July 31, 2001. The
December 31, 1999, borrowing base is $47 million but currently limited to the
$40 million commitment that will be reduced by $150,000 per month beginning in
July 2000. The credit facility is collateralized by substantially all of the
assets of the Company. At December 31, 1999, the $40 million commitment was
fully advanced.

          In July 1997, the Company entered into a senior subordinated term
note agreement and senior floating rate note agreement with The Prudential
Insurance Company of North America ("Prudential") for $15 million and $5
million, respectively. The $15 million term note agreement contained a warrant
purchase agreement authorizing Prudential to purchase up to 1 million shares
of the Company's common stock at an initial exercise price of $2.80 per share
until the termination date of the related term note. The fair value of the
warrants, $870,000, was determined using the Black-Scholes model and was
treated as an addition to paid-in capital. The resulting term note amount of
$14,130,000 will be accreted over the 10-year term using its effective
interest rate of 11.14%. The exercise price of the warrants was subsequently
lowered to $1.00 per share in 1999 in connection with the waiver of covenants.
The Company's cash pay-out over the term of the note is at the stated rate of
10.15%.

          The Company relies primarily on the collection of revenues
associated with rental-with-maintenance and contract compression contracts to
fund the Company's working capital and capital expenditure needs. Borrowings
from the Company's senior credit facility are used primarily to finance the
growth of the Company. The coordination of the cash flow from operations and
borrowings from the senior credit facility allows the Company to optimize its
cash flow.

          In July 1999, the Company sold approximately 5,000 horsepower of
idle compression equipment (approximately 2% of the total fleet) in a single
transaction for $2 million. The purchase and sale agreement contains put and
call features that permit 1) the Company to repurchase, at its option,
("Call") the equipment by the end of 1999 at cost, and 2) the purchaser to
("Put") the equipment back to the Company and recover the purchase price plus
accrued interest at 10%. The Put and Call features which were to expire on
December 31, 1999, have been extended by mutual agreement of the Company and
the purchaser to August 30, 2000. The Company has treated the transaction as a
loan for accounting purposes until such time as the put and call features have
either been exercised or expire. To that end, the $2 million sale is carried
as a $2 million current note payable at the fiscal year ended December 31,
1999.

          Net cash provided by operating activities increased to $6.7 million
in 1999 from $3.7 million in 1998 primarily due to inventory levels being
reduced in 1999 versus a $2.7 increase in 1998. Net cash used in investing
activities decreased to $9.9 million in 1999 from $23.7 million in 1998, due
primarily to decreased capital expenditures on the compressor fleet. Net cash
provided by financing activities decreased to $3.6 million in 1999 from $20
million in 1998, due primarily to decreased capital expenditures on the
compressor fleet. At December 31, 1999, the Company had current assets of
approximately $9.4 million and current liabilities of $8.4 million. At
December 31, 1999, the Company was out of compliance with certain financial
covenants with two of its credit facilities. The non-compliance was waived by
the lending institutions. As previously stated, the Company is fully advanced
on its senior bank revolving credit facility of $40 million and will not have
access to the net $7 million of unused borrowing base unless an additional
bank or institution is recruited into the credit facility. The Company will
recruit additional lenders into its credit facility, raise additional equity
capital or substantially slow its future growth.

          The Company has generated income and cash flow from operations in
1999 and 1998, the Company has funded its fleet expansion capital expenditures
through borrowings under its senior credit facility. As of December 31, 1999,
the Company has no availability under its senior credit facility. The Company
believes it could raise additional capital through a private or public equity
or debt financing; however, the Company cannot assure that such financing
would be available, or available under acceptable terms. If such financing
proved unavailable, the Company believes that a significant reduction in
capital expenditure related to the expansion of its compressor fleet would
allow the Company to continue as a going concern through 2000.

                                      12

<PAGE>

          On January 4, 2000, the Company announced that the previously
announced merger negotiations with Energy Transfer Company had been
terminated. Further, the Company's Board of Directors had authorized certain
board members to interview and engage an investment banker to explore
strategic alternatives and steps to maximize shareholder value. The Company
formally engaged a major investment bank in February 2000, for this purpose.
All strategic alternatives are being explored including the possible sale of
the Company.

ACCOUNTING PRONOUNCEMENTS

          In December 1997, the Company adopted Statement of Financial
Accounting Standards ("SFAS") No. 128, "Earnings per Share," effective January
1, 1997, resulting in the replacement of primary earnings per share ("EPS")
with a newly defined basic EPS and modification to the computation of dilutive
EPS. As a result, all prior period EPS data has been restated to conform to
the provisions of this statement. (Note 1). In addition, in December 1997, the
Company adopted SFAS No. 129, "Disclosure of Information about Capital
Structure," resulting in no material impact. In June 1997, the Financial
Accounting Standards Board ("FASB") issued SFAS No. 130, "Reporting
Comprehensive Income," and SFAS No. 131, "Disclosures about Segments of an
Enterprise and Related Information" effective for fiscal years beginning after
December 15, 1997. These statements have not had a material effect on the
Company's financial position or results of operations.

YEAR 2000

          The Company prepared a Year 2000 Plan and reviewed all Company
hardware, software and embedded systems for Year 2000 compliance. As part of
the review, the Company tested all critical compressor equipment and systems
to the extent possible. The Company incurred no material costs in testing its
internal compressor equipment and systems. There have been no issues involving
the Year 2000, therefore the Company does not anticipate any future concerns.

ITEM 7A.  QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

EFFECTS OF INFLATION

          In recent years inflation has not had a significant impact on the
Company's operations or financial condition. The impact of inflation on the
Company in the future will depend on the relative increases, if any, the
Company may realize from its compressor sales, interest rates on debt, rental
rates and the selling price of gas.

DERIVATIVE FINANCIAL INSTRUMENTS

          The Company had used derivative financial instruments such as
commodity futures agreements to hedge against fluctuations in oil and gas
prices. Gains and losses on these derivative instruments are recorded as
adjustments to oil and gas sales. The Board of Directors of the Company have
adopted a policy governing the use of derivative instruments which requires
that all derivatives used by the Company relate to an anticipated transaction
and prohibits the use of speculative or leveraged derivatives. As of December
31, 1999, the Company did not have any derivative financial instruments.

INTEREST RATE RISK

          Total debt at December 31, 1999, included $16 million of fixed rate
debt and $45 million of floating-rate debt attributed to borrowings. As a
result, the Company's annual interest cost will fluctuate based on changes in
short-term interest rates. The impact on annual cash flow of a 10% change in
the short-term interest rate would be less than $400,000.

Item begin at page 21 following page 20 hereof.

ITEM 9.   CHANGES IN AND DISAGREEMENTS WITH ACCOUNTANTS ON ACCOUNTING AND
          FINANCIAL DISCLOSURE

          On July 16, 1998, the Executive Committee of the Board of Directors
and the Audit Committee of the registrant determined to engage Arthur Andersen
LLP as its independent auditors for the fiscal year ending December 31, 1998.
On July 24, 1998, the registrant orally notified PricewaterhouseCoopers LLP
("PWC"); its independent auditor for the fiscal year ending December 31, 1997,
of this determination and that PWC would not continue to be engaged for the
fiscal year ending December 31, 1998. The determination to replace PWC was
made by the Audit Committee and the Executive Committee of the Board of
Directors of the registrant.

          The reports of PWC for the fiscal year ended December 31, 1997,
contained no adverse opinion or disclaimer of opinion and were not qualified
or modified as to uncertainty, audit scope or accounting principles. During
the fiscal year ended December 31, 1997, and during the period from December
31, 1997 to July 24, 1998, there were no disagreements between the registrant
and PWC concerning accounting principles or practices, financial statement
disclosure, or auditing scope or procedure.

                    REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS




To the Board of Directors and Stockholders of
OEC Compression Corporation


         We have audited the accompanying consolidated balance sheets of OEC
Compression Corporation (an Oklahoma Corporation) as of December 31, 1999 and
1998, and the related consolidated statements of operations, changes in
stockholders' equity and cash flows for the years then ended. These financial
statements are the responsibility of the Company's management. Our
responsibility is to express an opinion on these financial statements based on
our audits.

         We conducted our audits in accordance with auditing standards
generally accepted in the United States. Those standards require that we plan
and perform the audit to obtain reasonable assurance about whether the
financial statements are free of material misstatement. An audit includes
examining, on a test basis, evidence supporting the amounts and disclosures in
the financial statements. An audit also includes assessing the accounting
principles used and significant estimates made by management, as well as
evaluating the overall financial statement presentation. We believe that our
audits provide a reasonable basis for our opinion.

         In our opinion, the financial statements referred to above present
fairly, in all material respects, the financial position of OEC Compression
Corporation as of December 31, 1999 and 1998, and the results of its
operations and its cash flows for the years then ended, in conformity with
accounting principles generally accepted in the United States.

OIL AND GAS OPERATIONS

         During October 1997, the Company through its wholly owned subsidiary,
Sunterra, entered into a venture with Prize Petroleum, L.L.C. ("Prize") of
Tulsa, Oklahoma, to form Sunterra L.L.C. Sunterra L.L.C. was capitalized with
all of the Company's oil and gas properties and oil and gas properties
contributed by Prize. At June 30, 1999, the Company had an approximate 82%
ownership in Sunterra L.L.C. The Company had effective control over the
operations of Sunterra L.L.C. and has consolidated its results since its
formation, October 1, 1997 until the sale of its interest in the Sunterra
L.L.C. to Prize on July 2, 1999.

         On July 2, 1999, Sunterra sold 100% of its interest in Sunterra
L.L.C. to Prize. Sunterra received $1 million in cash and the Will-O-Mills gas
treating plant located in southwest Texas. The Will-O-Mills gas treating plant
is a 300 gpm amine plant, which extracts carbon dioxide, and minor amounts of
hydrogen sulfide from natural gas flowed to the plant by area producers under
long-term treating contracts. The Sunterra L.L.C sale effectively removed the
Company from the oil and gas production business.

         Prior to the sale of the Sunterra L.L.C. the Company accounted for
its oil and gas exploration and development activities on the full cost method
of accounting prescribed by the Securities and Exchange Commission ("SEC").
Accordingly, all productive and non-productive costs incurred in connection
with the acquisition, exploration and development of oil and gas reserves are
capitalized

                                     25

<PAGE>

and amortized using the units-of-production method based on proved oil and gas
reserves. Beginning in 1997, the Company's oil and gas reserves were estimated
by a petroleum engineer who was an employee of the Company.

           The depreciation, depletion and amortization rates were $.62, $.51
and $.43 per equivalent mcf produced in 1999, 1998 and 1997, respectively. In
the event the unamortized cost of oil and gas properties being amortized
exceeds the full-cost ceiling as defined by the SEC, the excess is charged to
expense in the period during which such excess occurs.

         Sales and abandonments of properties were accounted for as
adjustments of capitalized costs with no gain or loss recognized unless a
significant amount of reserves were involved. Since all of the Company's oil
and gas properties were located in the United States, a single cost center was
used with one amortization base.

HEDGING ACTIVITY

         As a part of its risk management program, Sunterra L.L.C. entered
into non-traded natural gas price swap contracts. Gains and losses related to
the contracts were deferred and recognized in income when the hedging
transaction occurs. Prior to the sale of the oil and gas properties, Sunterra
L.L.C. had recognized a gain of $137,000 due to hedging activity.

GOODWILL AND OTHER INTANGIBLES

         Goodwill is amortized using the straight-line method over the
estimated benefit periods of 24 to 30 years. Non-compete agreements are
amortized using the straight-line method over the life of the agreements of
one to three years. Debt issue costs are amortized using the straight-line
method over the life of the agreements ranging from 7 to 10 years.

CASH DEFICIT

         On March 10, 1998, the Company replaced its existing senior bank
credit facility with a new senior bank credit facility. The prior facility
automatically funded or withdrew the balance in the Company's bank account
daily. The new facility requires the Company to formally request advances to
fund operations. This change has at times caused the Company to incur a cash
deficit for financial reporting purposes due to outstanding checks, which will
be funded through cash flow from operations or borrowings from the new
facility. This cash deficit was necessary to maximize the Company's cash flow
and in no way impairs the Company's ability to fund its daily operations. The
cash deficit is included in the Company's Balance Sheet in the Current
Liabilities section under the caption "accounts payable and accrued
liabilities." At December 31, 1998, the Company had outstanding checks in
excess of its cash balance of approximately $1.3 million. The aforementioned
cash strategy was discontinued in 1999 when the bank facility was fully
funded. At December 31, 1999, the Company had a positive cash balance.

INCOME TAXES

         The Company uses Statement of Financial Accounting Standards ("SFAS")
No. 109 "Accounting for Income Taxes." This standard requires the measurement
of deferred tax assets for deductible temporary differences and deferred tax
liabilities for taxable temporary differences. Measurement of current and
deferred tax liabilities and assets is based on provisions of enacted tax law;
the effects of future changes in tax laws or rates are not included in the
measurement. Deferred tax liabilities primarily result from the recognition of
depreciation, depletion and amortization in different periods for financial
reporting and tax purposes. Income tax benefit or expense is the tax payable
for the current year and the change during that year in deferred tax assets
and liabilities.

STOCK-BASED COMPENSATION

         The Company applies Accounting Principles Board ("APB") Opinion No.
25 in accounting for its stock option plans. Under this standard, no
compensation expense is recognized for grants of options which include an
exercise price equal to or greater than the market price of the stock on the
date of grant. Accordingly, based on the Company's grants in 1999, 1998 and
1997, no compensation expense has been recognized. As provided by SFAS No. 123
"Accounting for Stock-Based Compensation," the Company has disclosed the pro
forma effects of recording compensation for such option grants based on their
fair value in Note 9 to the financial statements.

CONCENTRATIONS OF CREDIT RISK

         Financial instruments which subject the Company to concentrations of
credit risk consist primarily of trade receivables with a variety of oil and
gas companies. The Company generally does not require collateral related to
receivables. Such credit risk is considered by management to be limited due to
the large number of customers comprising the Company's customer base.

                                     26

<PAGE>

         Financial instruments, which are potentially subject to
concentrations of credit risk, consist principally of cash, cash equivalents
and accounts receivable. Cash and cash equivalents are placed with high credit
quality financial institutions to minimize risk. The carrying amounts of these
instruments approximate fair value because of their short maturities.

         Fair values of the Company's financial instruments are estimated
through a combination of management's estimates and by reference to quoted
prices from market sources and financial institutions, if available. As of
December 31, 1999, the fair market value of existing debt was equal to the
carrying value of the existing debt.

CAPITAL RESOURCES

        Although, the Company has generated income and cash flow from
operations in 1999 and 1998, the Company has funded its fleet expansion
capital expenditures through borrowings under its senior credit facility. As
of December 31, 1999, the Company has no availability under its senior credit
facility. The Company believes it could raise additional capital through a
private or public equity or debt financing; however, the Company cannot
assure that such financing would be available, or available under acceptable
terms. If such financing proved unavailable, the Company believes that a
significant reduction in capital expenditure related to the expansion of its
compressor fleet would allow the Company to continue as a going concern
through 2000.

         On January 4, 2000, the Company announced that the previously
announced merger negotiations with Energy Transfer Company had been
terminated. Further, the Company's Board of Directors had authorized certain
board members to interview and engage an investment banker to explore
strategic alternatives and steps to maximize shareholder value. The Company
formally engaged a major investment bank in February 2000, for this purpose.
All strategic alternatives are being explored including the possible sale of
the Company.

SHOP CLOSING COSTS

         In the fourth quarter of 1997, the Company recognized a $307,000
charge in connection with the closure of its Oklahoma City, Oklahoma, Kilgore,
Texas and Columbia, Mississippi shop facilities. The charge was comprised of
provisions for approximately $143,000 related to severance costs,
approximately $130,000 for moving and relocation costs, approximately $23,000
for transfer bonuses and approximately $11,000 related to the loss on sale of
the Columbia, Mississippi facility. Approximately $34,000 of the costs were
paid in 1997. The remaining $273,000 of costs were paid during 1998.

ACCOUNTING ESTIMATES

         The preparation of financial statements in conformity with generally
accepted accounting principles 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 revenue and expenses during the
reporting period. Actual results could differ from those estimates.

EARNINGS PER SHARE

         Approximately 10,897,000 of common stock options and warrants
outstanding at December 31, 1997, were excluded from the computation of
dilutive earnings per share ("EPS") because their effect on EPS would have
been anti-dilutive for that period. Basic EPS is computed based on weighted
average number of shares of common stock outstanding during the period.
Dilutive EPS is computed based on weighted average number of shares of common
stock outstanding during the period adjusted for the effect of dilutive
securities.

         The following is a reconciliation of basic and dilutive EPS
computations:

RECLASSIFICATIONS

         Certain prior year amounts have been reclassified to conform with the
current year presentation.

ISSUED ACCOUNTING PRONOUNCEMENTS

         In December 1997, the Company adopted SFAS No. 129, "Disclosure of
Information about Capital Structure," resulting in no material impact. In
addition, in June 1997, the Financial Accounting Standards Board ("FASB")
issued SFAS No. 130, "Reporting Comprehensive Income," and SFAS No. 131,
"Disclosures about Segments of an Enterprise and Related Information,"
effective for fiscal years beginning after December 15, 1997. These
statements, were adopted in 1998 and did not have a material effect on the
Company's financial position or results of operations.

         In December 1998, the Company adopted Statement of Position ("SOP")
98-5 "Reporting on the Costs of Start-Up Activities." SOP 98-5 requires cost
of start-up activities and organization costs to be expensed as incurred. The
Company incurred a charge-off of unamortized original organizational costs
upon adoption of SOP 98-5. The effect of adopting SOP 98-5 decreased the 1998
income from operations, net income and income per share (dilutive) by
approximately $112,000, $69,000 and $.00, respectively.

         In June 1999, the FASB issued SFA No. 133, "Accounting for Derivative
Financial Instruments and Hedging Activities," which is effective for all
fiscal years beginning after June 15, 2000. If the Company had adopted SFAS
No. 133 during 1999, there would be no effect on the Company's financial
statements as the Company had no hedges outstanding at December 31, 1999.
Although the future impact of adopting SFAS 133 has not been determined yet,
the Company does not believe the impact will be material.

NOTE 2    ACQUISITION OF SUBSIDIARY

          On August 6, 1997, the Company completed the acquisition of 100% of
the common stock of Ouachita and the majority of the assets of both Ouachita
Compression Group, LLC and Ouachita Energy Partners, LTD. Under the terms of
the acquisition the Ouachita companies' shareholders received 7.6 million
shares of the Company's common stock valued at $12,540,000, and approximately
$24 million in cash and assumption of debt. The acquisition was accounted for
using the purchase method of accounting and accordingly, the results of
operations of Ouachita are included in the Company's results of operations
since the date of acquisition. The aggregate purchase price of $36,560,000 has
been allocated as follows (in thousands):

$701,000 which was assumed in the acquisition was subsequently settled by the
issuance of an additional 286,976 shares of the Company's common stock.

NOTE 3   SALE OF COMMON STOCK AND ISSUANCE OF CONTINGENT WARRANTS

         Effective December 19, 1996, the Company sold to HACL, Ltd., a
private investment group, 8,000,000 shares of its common stock and warrants
which, upon satisfying certain vesting requirements, entitle the purchase of
an additional 8,000,000 shares of its common stock at a price of $.91 per
share, for aggregate consideration of $4,400,000. The Company reported the
cash consideration received, net of related costs, of $4,400,000 as an
addition to common stock and paid-in capital. The "fair value" of the warrants
was estimated by an independent valuation firm to be $1,440,000, which the
Company reported as an addition to paid-in capital offset by a deferred
expense contra-equity account. A committee of the Board of Directors
determined that the warrants fully vested during the third quarter of 1997.
Accordingly, the $1,440,000 was expensed in the third quarter of 1997. The
warrants for the corresponding 8,000,000 shares of common stock have not been
exercised as of December 31, 1999.

NOTE 4   PROVISION TO REDUCE THE CARRYING VALUE OF OTHER EQUIPMENT

         In December 1998 the Company as part of a Settlement Agreement (Note
10) agreed to exchange an airplane, owned by the Company, for shares of the
Company's common stock and value related to a truck. It was determined during
negotiations that the airplane be reduced to its estimated fair value of
approximately $290,000, resulting in a provision to reduce the carrying value of
the airplane of $162,000.

</TABLE>

         Compressor equipment held by the Company for rental purposes is
stated at cost and depreciated over the serviceable life of the equipment.
Leased compressor equipment is depreciated on a straight-line basis over an
estimated useful life of 12 to 20 years. Due to the nature of compressor
equipment no depreciation is recorded for idle equipment not under contract.
Depreciation is resumed when the compressor equipment is contracted.
Associated with its acquisition of Ouachita, the Company changed its estimate
of useful lives for certain of its compressor equipment to 15 to 20 years with
capitalized overhauls on compressor rental equipment depreciated over five
years. The effect of these changes decreased the 1997 loss from operations,
net loss and loss per share (dilutive) by approximately $265,000, $165,000 and
$.01, respectively. Buildings and other equipment are stated at cost and
depreciated over their estimated useful lives of 30 years and 5 years,
respectively.

         Repairs and maintenance are charged to expense as incurred and major
overhauls and betterments are capitalized. Upon sale or retirement of
equipment, the cost of the equipment disposed of and the related accumulated
depreciation are removed from the accounts and the resulting gain or loss is
reflected in operations.

         Long-lived assets are evaluated for impairment whenever events or
changes and circumstances indicate that the carrying value of an asset may not
be recoverable. Assets determined to be impaired based on estimated
undiscounted future net cash flows are reduced to estimated fair value.
Changes in such estimates could cause the Company to reduce the carrying value
of its property and equipment and goodwill.

         During 1999, the Company completed purchase leasebacks, where the
Company bought compressors from our customers then leased the compressors back
to its customers. The purchase leasebacks accounted for the expenditure of
approximately $1.5 million and an increase in horsepower of over 10,000 with
lease terms from six months to five years.

</TABLE>

    (a)  On March 10, 1998, the Company replaced its previously existing $20
         million senior bank credit facility with a new senior bank credit
         facility. The initial maximum commitment was $40 million, which can be
         expanded to $60 million with the future addition of other
         participating financial institutions. The facility is a borrowing base
         revolver maturing in July, 2001, and due in its entirety at that
         time. The December 31, 1999, borrowing base of $47 million exceeds the
         $40 million commitment. Interest on the new facility is comprised of
         conforming and non-conforming borrowing bases which accrue interest at
         LIBOR plus 1.75% and LIBOR plus 2.25%, respectively. Initial
         borrowings are at Prime until converted to LIBOR loans. At December
         31, 1999, the average interest rate on outstanding loans was 7.91%.
         The credit facility is collateralized by substantially all of the
         assets of the Company with the exception of the Company's gas treating
         plant. At December 31, 1999 the current available portion was zero.
         Beginning in July 2000, the $40 million commitment will decrease by
         $150,000 per month until due in July 2001.

    (b)  In December 1997, Sunterra L.L.C., entered into a new $10 million bank
         revolving credit facility with borrowings limited to a borrowing base
         determined on the value of the underlying oil and gas reserves. This
         facility was assumed by Prize when they acquired the oil and gas
         properties.

    (c)  In July 1997, the Company entered into senior subordinated term note
         agreements with The Prudential Insurance Company of North America
         ("Prudential") for $15 million and $5 million. The $15 million term
         note agreement contained a warrant purchase agreement authorizing
         Prudential to purchase up to 1 million shares of the Company's common
         stock at an initial exercise price of $2.80 per share until the
         termination date of the related term note. The fair value of the
         warrants, $870,000, was determined using the Black-Scholes model and
         was reported as an addition to paid-in capital and as a discount on
         the notes. The resulting term note amount of $14,130,000 will be
         accreted over the ten-year term using its effective interest rate of
         11.14%. The Company's cash payout over the term of the notes is at the
         stated rate of 10.15%. The warrants were adjusted to an exercise price
         of $1.45 on July 2, 1999 and again on December 1, 1999 the warrants
         were repriced to an exercise price of $1.00 to garnish waivers of the
         debt covenants. The $5 million note accrues interest at LIBOR plus
         2.25%. At December 31, 1999, the rate was 8.73%.

    (d)  Covenants related to the debt agreements include the maintenance of
         specified levels of working capital, tangible net worth and debt
         service ratio, as defined by the agreements. Additionally, the
         agreements prohibit the payment of dividends and place limitations on
         the repurchase of shares of the Company's stock and the incurrence of
         new borrowings. During 1999, the Company was not in compliance with
         the interest coverage, G&A coverage, and EBITDA multiple covenants of
         its debt agreements, which were waived or modified by the lender.

        Long-term debt maturities as of December 31, 1999, are $2,918,000,
$39,126,000, $0, $0 and $5,000,000 in 2000, 2001, 2002, 2003 and 2004,
respectively, with a remainder of $14,256,000 due in subsequent years. Based
on the interest rates currently available to the Company for borrowings with
similar terms and maturities, the long-term debt at December 31, 1999,
approximates fair value. There was not any interest capitalized in 1999. The
Company has generated income and cash flow from operations in 1999 and 1998,
the Company has funded its fleet expansion capital expenditures through
borrowings under its senior credit facility. As of December 31, 1999, the
Company has no availability under its senior credit facility. The Company
believes it could raise additional capital through a private or public equity
or debt financing; however, the Company cannot assure that such financing
would be available, or available under acceptable terms. If such financing
proved unavailable, the Company believes that a significant


                                     31

reduction in capital expenditure related to the expansion of its compressor
fleet would allow the Company to continue as a going concern through 2000.

NOTE 9   COMPENSATION PLANS

         EMPLOYEE STOCK OPTION PLAN. On August 8, 1989, the Board of Directors
of the Company adopted and its stockholders approved an Employee Stock Option
Plan (the "Stock Option Plan") which became effective on that date. An
aggregate of 130,000 shares of common stock were initially available for sale
upon exercise of options granted under the Stock Option Plan, provided that
the number of shares available for options which may be granted under the
Stock Option Plan will automatically be increased without action of the
directors or stockholders of the Company to an amount equal to (when added to
the number of shares of common stock subject to all other options granted by
the Company) 8% of the issued and outstanding shares of common stock upon each
issuance of shares of common stock occurring after February 28, 1990 (other
than issuance of shares upon the exercise of options granted under the Stock
Option Plan). The Board of Directors may make authorized but unissued common
stock available for the exercise of options or it may utilize shares held in
treasury. On February 4, 1999, the Board of Directors approved the issuance of
198,874 stock options under the Stock Option Plan. The Stock Option Plan is
not subject to the provisions of the Employee Retirement Income Security Act
of 1974 and the options are not "incentive stock options," as such term is
defined in Internal Revenue Code Section 422A. As of December 31, 1999,
options to acquire 1,205,882 shares of common stock at prices ranging from
$.50 to $2.25 were outstanding.

         DIRECTOR STOCK OPTION PLANS. On August 8, 1989, the Board of
Directors adopted and the stockholders approved a Director Stock Option Plan
(the "1989 Director Plan") which became effective on that date. An aggregate
of 170,000 shares of common stock are available for sale upon exercise of
options granted under the 1989 Director Plan. At December 31, 1999, options
for 30,000 shares at a price of $2.50 were exercisable. As of December 31,
1999, no options had been exercised. The 1989 Director Plan is not subject to
the provisions of the Employee Retirement Income Security Act of 1974 and the
options will not be "incentive stock options," as such term is defined in
Internal Revenue Code Section 422A.

         On May 25, 1994, the Board of Directors adopted and the stockholders
approved the 1994 Director Stock Option Plan which became effective on that
date. Options to acquire an aggregate of 355,000 shares of common stock were
initially granted; however, options to acquire 280,000 shares of common stock
were surrendered for cancellation in 1996. At December 31, 1999, options for
75,000 shares at a price of $1.40 were exercisable. As of December 31, 1999,
no options had been exercised. These options expire on May 24, 2004.

         On March 27, 1996, the Board of Directors adopted and on May 29,
1996, the stockholders approved the Director Stock Plan, which became
effective on the date of its approval by the Company's stockholders. Under the
Director Stock Plan, non-qualified stock options may be issued to non-employee
directors of the Company. An aggregate of 500,000 shares of common stock are
reserved for issuance upon the exercise of options granted under the Director
Stock Plan. The Director Stock Plan provided for, effective upon its approval
by the Company's stockholders, the automatic grant to eligible directors of an
option to purchase either (i) 50,000 shares of common stock, if such eligible
director had been an employee of the Company at any time, or (ii) 17,500
shares of common stock, if such eligible director had never been an employee
of the Company. On each anniversary of each eligible director's election to
the Board for the term as a director which he or she is currently serving,
each such director will be granted an option to purchase 6,666 shares of
common stock. In addition, upon an eligible director's initial election or
appointment to the Board, such director will receive the grant of an option to
purchase 10,000 shares of common stock. At December 31, 1999, options to
acquire 302,488 shares of common stock at prices ranging from $.56 to $2.31
were outstanding. As of December 31, 1999, no options issued under the
Director Stock Plan had been exercised. The Director Stock Plan is not subject
to any of the provisions of the Employee Retirement Income Security Act of
1974 and the options will not be "incentive stock options," as such term is
defined in Internal Revenue Code Section 422A.

The Company applies APB Opinion No. 25 in accounting for its employee and
director stock option plans. Accordingly, based on the nature of the Company's
grants of options, no compensation cost has been recognized in 1999, 1998, or
1997. Had compensation been determined on the basis of fair value pursuant to
SFAS No. 123, "Accounting for Stock-Based Compensation" net loss per share
would have been as follows at December 31:

         The fair value of each option granted is estimated using the
Black-Scholes model. The Company's estimated stock volatility was 68%, 75%,
and 86% for 1999, 1998, and 1997, respectively, based on previous stock
performance. Dividend yield was estimated to remain at zero with a risk-free
interest rate of 6% for 1997 through 1999. Expected life was estimated at four
to eight years based on prior experience depending on the vesting periods
involved and the make up of participating employees within each grant. The
weighted average fair value of options granted during 1999, 1998, and 1997, as
estimated using the Black-Scholes option pricing model, was $1.12, $1.31, and
$1.06 respectively.

         EMPLOYEE BENEFIT PLAN. Substantially all of the Company's employees
are covered by a defined contribution 401(k) plan adopted in 1991. The Company
matches 50% of the employee contributions up to a limit of 4% of employee
annual earnings. All


                                     35

matching contributions are made in Company stock. Total expense related to the
plan amounted to $79,000 in 1999, $87,000 in 1998, $50,000 in 1997.

         OTHER. Non-qualified options for 15,000 shares at a price of $2.50
per share were granted to a former employee of the Company in 1990, all of
which are currently exercisable with an expiration date of January 2030.

NOTE 10  TRANSACTIONS WITH RELATED PARTIES

         The Company transacts business with certain companies, which are
directly controlled by members of the Company's Board of Directors and
employees. The terms of these transactions are equivalent to the terms of
transactions conducted with non-related parties.

         On December 16, 1998, the Company, Dennis Estis, the two other
shareholders who granted a proxy to Mr. Estis and certain other parties
entered into a Settlement Agreement. Among other things, the Settlement
Agreement (i) prohibits Mr. Estis from participating in any proxy solicitation
relating to certain actions, (ii) requires termination of the proxies granted
to him by the two other shareholders, (iii) dismissed a lawsuit filed by Mr.
Estis, (iv) released certain claims between the parties, (v) provided for a
"standstill" agreement until June 30, 1999, (subject to possible extension and
reinstatement as described below) prohibiting Mr. Estis from participating in
enumerated actions relating to control of the Company and (vi) requires the
Company to reimburse Mr. Estis for certain of his out-of-pocket expenses. The
Company has agreed to use its best effort to sell or assist Mr. Estis to sell
at least one-half of his shares of common Stock at $2.00 or more per share. If
such a sale is not completed prior to June 30, 2000, then Mr. Estis'
non-competition agreement shall be terminated except as to Mr. Estis'
agreement not to solicit or hire employees of the Company. If the sale by Mr.
Estis occurs prior to December 31, 2001, then the standstill agreement
described above will be extended or reinstated, as the case may be, through
December 31, 2001. As part of this settlement, Mr. Estis, in exchange for
shares of the Company's common stock and the value of a truck, purchased an
airplane from the Company. In closing this transaction the Company incurred an
impairment of $162,000 on the airplane.

         Through its acquisition of Ouachita, the Company acquired note
receivables of approximately $332,000 from the former owner of Ouachita, who
is now a director of the Company and another party. Interest receivable
related to these notes at December 31, 1999, 1998 and 1997, was approximately
$52,000, $30,000 and $9,000, respectively. Interest on these notes accrues at
the rate of 6.5% and is payable when the note matures.

         On December 31, 1997, the Company sold its facility located in
Columbia, Mississippi to a current member of the Company's Board of Directors.
The Company received $316,000 in cash resulting in a loss of $11,000. During
1999, the Company remitted payments to this related-party totaling
approximately $499,000 for service work on compression component parts at this
facility. The Company owed approximately $12,000 to the director related to

</TABLE>

         All of the Company's reserves were attributable to Sunterra L.L.C. for
which there was an approximate 18% minority interest.

         Proved reserves are those quantities which, upon analysis of geological
and engineering data, appear with reasonable certainty to be recoverable in the
future from known oil and gas reservoirs under existing economic and operating
conditions. Proved developed reserves are those reserves which can be expected
to be recovered through existing wells with existing equipment and operating
methods.

                                      38
<PAGE>

         Oil and gas reserves cannot be measured exactly. Estimates of oil and
gas reserves require extensive judgments of reservoir engineering data and are
generally less precise than other estimates made in connection with financial
disclosures.

         Assigning monetary values to such estimates does not reduce the
subjectivity and changing nature of such reserve estimates. Indeed the
uncertainties inherent in the disclosure are compounded by applying additional
estimates of the rates and timing of production and the costs that will be
incurred in developing and producing the reserves. The information set forth
herein is therefore subjective and, since judgments are involved, may not be
comparable to estimates submitted by other oil and gas producers. In addition,
since prices and costs do not remain static and no price or cost escalation's or
de-escalation's have been considered, the results are not necessarily indicative
of the estimated fair market value of estimated proved reserves nor of estimated
future cash flows.

            STANDARDIZED MEASURE OF DISCOUNTED FUTURE NET CASH FLOWS

         The standardized measure of discounted future net cash flows ("SMOG")
was calculated using year-end prices and costs, and year-end statutory tax
rates, adjusted for permanent differences, that relate to existing proved oil
and gas reserves. Future net cash flows are as follows:
