<DIV align="left" style="font-size: 10pt; margin-top: 6pt"><strike>(3)</strike> &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&#147;EBITDA&#148; is a non-GAAP financial measure of earnings (net income) from continuing operations
before interest, taxes, depreciation, and amortization. This term, as used and defined by us, may
not be comparable to similarly titled measures employed by other companies and is not a measure of
performance calculated in accordance with GAAP. EBITDA should not be considered in isolation or as
a substitute for operating income, net income or loss, cash flows provided by operating, investing
and financing activities, or other income or cash flow statement data prepared in accordance with
GAAP. However, management believes EBITDA is useful to an investor in evaluating our operating
performance because:

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;There are material limitations to using EBITDA as a measure of performance,
including the inability to analyze the impact of certain recurring items that materially affect our
net income or loss, and the lack of comparability of results of operations of different companies.

</DIV>


<DIV align="left" style="font-size: 10pt; margin-top: 6pt"><U style="border-bottom: 1px solid #000000">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;We define gross margin as total revenue less cost of sales (excluding
depreciation and amortization expense). Gross margin is included as a supplemental disclosure
because it is a primary measure used by our management as it represents the results of revenue and
cost of sales (excluding depreciation and amortization expense), which are key components of our
operations. Gross margin differs from gross profit which includes depreciation expense. We
believe gross margin is important because it focuses on the current operating performance of our
operations and excludes the impact of the prior historical costs of the assets acquired or
constructed that are utilized in those operations, the indirect costs associated with our selling,
general and administrative activities, the impact of our financing methods and income taxes.
Depreciation expense may not accurately reflect the costs required to maintain and replenish the
operational usage of our assets and therefore may not portray the costs from current operating
activity. Rather, depreciation expense reflects the systematic allocation of historical fixed
asset values over the estimated useful lives.</U>

compared to net income. These limitations are primarily due to the exclusion of certain expenses.
Each of these excluded expenses is material to our consolidated results of operations. Because we
use capital assets, depreciation expense is a necessary element of our costs and our ability to
generate revenue and selling, general and administrative expense is a necessary cost to support our
operations and required corporate activities. In order to compensate for these limitations,
management uses this non-GAAP measure as a supplemental measure to other GAAP results to provide a
more complete understanding of our performance.</U>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt"><U style="border-bottom: 1px solid #000000">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;As an indicator of our operating performance, gross margin should not be
considered an alternative to, or more meaningful than, net income as determined in accordance with
GAAP. Our gross margin may not be comparable to a similarly titled measure of another company
because other entities may not calculate gross margin in the same manner.</U>

</DIV>


<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;We fabricate, manufacture, rent and sell natural gas compressors and related equipment. Our primary
focus is on the rental of natural gas compressors. Our rental contracts generally provide for
initial terms of six to 24&nbsp;months. After the initial term of our rental contracts, most of our
customers have continued to rent our compressors on a month-to-month basis. Rental amounts are paid
monthly in advance and include maintenance of the rented compressors. As of December&nbsp;31, 2006, we
had 974 natural gas compressors totaling approximately 112,718 horsepower rented to 84 third
parties, compared to 820 natural gas compressors totaling approximately 90,486 horsepower rented to
75 third parties at December&nbsp;31, 2005.

<DIV style="font-family: 'Times New Roman',Times,serif">

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;In general, we expect our overall business activity and revenues to track the level of
activity in the natural gas industry, with changes in domestic natural gas production and
consumption levels and prices more significantly affecting our business than changes in crude oil
and condensate production and consumption levels and prices. We also believe that demand for
compression services and products is driven by declining reservoir pressure in maturing natural gas
producing fields and, more recently, by increased focus by producers on non-conventional natural
gas production, such as coalbed methane, gas shales and tight gas, which typically requires more
compression than production from conventional natural gas reservoirs.
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Demand for our products and services have been strong throughout 2005 and 2006. We believe
demand will remain strong throughout 2007 due to high oil and natural gas prices and increased
demand for natural gas. Because of these market fundamentals for natural gas, we believe the
long-term trend of activity in our markets is favorable. However, these factors could be more than
offset by other developments affecting the worldwide supply and demand for natural gas.
Additionally, activity created by recent increases in the price of natural gas may make it
difficult to meet the demands of our markets.
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;For fiscal year 2007, our forecasted capital expenditures are approximately $27 to $32
million, primarily for additions to our compressor rental fleet. We believe that the proceeds from
our public offering of common stock we completed in March&nbsp;2006, together with funds available to us
under our bank credit facility and cash flows from operations will be sufficient to satisfy our
capital and liquidity requirements through 2007. We may further require additional capital to fund
any unanticipated expenditures, including any acquisitions of other businesses. Additional capital
may not be available to us when we need it or on acceptable terms.

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Total revenues for the year ended December&nbsp;31, 2005 increased 209.0% to $49.3&nbsp;million, as
compared to $16.0&nbsp;million for the year ended December&nbsp;31, 2004. The increase in revenue reflects
the increase in our rental revenue and the addition of revenue from our acquisition of SCS.
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Sales revenue increased from $3.6&nbsp;million to $30.3&nbsp;million, or 742.7%, for the year ended
December&nbsp;31, 2005, compared to the year ended December&nbsp;31, 2004. The increase was mainly the result
of the sale of compressor units to outside third parties by SCS.
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Service and maintenance revenue increased from $1.9&nbsp;million to $2.4&nbsp;million, or 29.3%, for the
year ended December&nbsp;31, 2005, compared to the year ended December&nbsp;31, 2004. The increase was mainly
the result of additional third party labor sales in our New Mexico area and Michigan branches.
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Rental revenue increased from $10.5&nbsp;million to $16.6&nbsp;million, or 58.3%, for the year ended
December&nbsp;31, 2005, compared to the year ended December&nbsp;31, 2004. The increase was mainly the result
of units added to our rental fleet and rented to third parties. At December&nbsp;31, 2005, we had 865
compressor packages in our rental fleet, up from 586 units at December&nbsp;31, 2004. The average
monthly rental rate per unit at December&nbsp;31, 2005 was $2.1 thousand, as compared to $2.0 thousand
at December&nbsp;31, 2004.
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The overall gross margin percentage, exclusive of depreciation, decreased to 36.4% for the
year ended December&nbsp;31, 2005, as compared to 56.4% for the year ended December&nbsp;31, 2004. This
decrease resulted mainly from the relative increase in compressor sales revenue as a percentage of
the total revenue. Our rental fleet carried a gross margin averaging 60.7% for 2005, and compressor
and parts sales margins averaged 23.0%.
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Selling, general and administrative expense increased from $2.7&nbsp;million to $4.9&nbsp;million, or
84.4%, for the year ended December&nbsp;31, 2005, as compared to the year ended December&nbsp;31, 2004. This
was mainly the result of the increased expenses attributed to our acquisition of SCS. SCS accounted
for approximately $1.5&nbsp;million of the total selling, general and administrative expenses for the
year ended December&nbsp;31, 2005.
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Depreciation and amortization expense increased 72.8% from $2.4&nbsp;million to $4.2&nbsp;million for
the year ended December&nbsp;31, 2005, compared to the year ended December&nbsp;31, 2004. This increase was
the result of 279 new gas compressor rental units being added to rental equipment from December&nbsp;31,
2004 to December&nbsp;31, 2005, thus increasing the depreciable base.
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Other income decreased approximately $1.2&nbsp;million for the year ended December&nbsp;31, 2005,
compared to the same period in 2004. This decrease was due mainly to the $1.5&nbsp;million that was
received in the year ended December&nbsp;31, 2004 as life insurance proceeds from the death of our
former Chief Executive Officer, offset by additional interest income from our money market accounts
in 2005.
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Interest expense increased by $1.2&nbsp;million, or 138%, for the year ended December&nbsp;31, 2005,
compared to the same period ended December&nbsp;31, 2004, mainly due to increased debt incurred to
finance rental equipment additions, debt related to our acquisition of SCS and increased interest
rates.

</DIV>


<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Various federal, state and local laws and regulations covering the discharge of materials into
the environment, or otherwise relating to protection of human safety and health and the
environment, affect our operations and costs. Compliance with these laws and regulations could
cause us to incur remediation or other corrective action costs or result in the assessment of
administrative, civil and criminal penalties and the issuance of injunctions delaying or
prohibiting operations. In addition, we have acquired certain properties and plant facilities from
third parties whose actions with respect to the management and disposal or release of hydrocarbons
or other wastes were not under our control. Under environmental laws and regulations, we could be
required to remove or remediate wastes disposed of or released by prior owners. In addition, we
could be responsible under environmental laws and regulations for properties and plant facilities
we lease, but do not own. Compliance with such laws and regulations increases our overall cost of
business, but has not had a material adverse effect on our operations or financial condition. It is
not anticipated, based on current laws and regulations, that we will be required in the near future
to expend amounts that are material in relation to our total expenditure budget in order to comply
with environmental laws and regulations but, such laws and regulations are frequently changed and
we are unable to predict the ultimate cost of compliance. We also could incur costs related to the
clean up of sites to which we send equipment and for damages to natural resources or other claims
related to releases of regulated substances at such sites.

securities, subordinated debt, bank borrowings and cash flow from operations. Proceeds of
financings have been primarily used to repay debt, to fund the manufacture and fabrication of
additional units for our rental fleet of natural gas compressors and for acquisitions. <strike>At December
31, 2005, we had cash and cash equivalents of approximately $3.3&nbsp;million, working capital of $13.4
million and total debt of $28.2&nbsp;million, of which approximately $6.0&nbsp;million was classified as
current. At that same date, we also had letters of credit outstanding in the aggregate face amount
of $2.0&nbsp;million which secured payment of our subordinated debt in the amount of $3.0&nbsp;million. We
had positive net cash flow from operating activities of approximately $3.8&nbsp;million during 2005.
This was primarily from net income of $4.4&nbsp;million, plus depreciation and amortization of $4.2
million, an increase in deferred taxes of $2.4&nbsp;million, an increase in accounts payable and accrued
liabilities of $0.4&nbsp;million, offset by an increase in trade accounts receivable of $1.4&nbsp;million,
deferred income of $0.9&nbsp;million, and an increase in inventory of $5.7&nbsp;million.</strike>

</DIV>


<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;In 2001, the Company completed an offering of units consisting of subordinated debt and
warrants. The balance of the subordinated debt, net of unamortized discount of $90 thousand, was
$1.4&nbsp;million at December&nbsp;31, 2004. All amounts due on the notes were paid in full during 2005. Each
unit consisted of a $25 thousand 10% subordinated note due December&nbsp;31, 2006 and a five-year
warrant to purchase 10 thousand shares of the Company&#146;s common stock at $3.25 per share. Interest
only was payable annually, with all principal due at maturity. Warrants to purchase 61.6 thousand
shares were also granted on the same terms to a placement agent in connection with the offering.
Certain stockholders, officers and directors purchased units in the subordinated debt offering,
(totaling $259 thousand in notes and warrants representing 104 thousand shares) on the same terms
and conditions as non-affiliated purchasers in the offering. As of December&nbsp;31, 2006, none of the
warrants remained outstanding.
