     The following summary is qualified in its entirety by the more detailed
information appearing elsewhere in this Offering Memorandum and the Exhibits
attached hereto. Prospective investors of the Shares should carefully consider
the factors set forth under "Risk Factors."

                                  The Company

     The Company was organized in October 1990 for the purpose of acquiring,
manufacturing, selling, leasing, maintaining and refurbishing compressors
utilized by the natural gas industry. For a more detailed description of the

                                  The Offering

                                    cash out of the subscribing offeree's own
                                    funds or by delivery of a four year note,
                                    but not including shares which may be
                                    acquired pursuant to options granted under
                                    the Employee Option Plan. See "The
                                    Offering."

Use of Proceeds:                    All of the net proceeds of this offering
                                    will be used for general corporate purposes,
                                    including working capital.

     The Company reserves the right to withdraw this offering and return all
subscriptions or modify this offering at any time during the term of this

offerees; with a pro rata share of interest earned thereon,

                                  THE COMPANY

     Hanover Compressor Company is a corporation organized under the laws of the
State of Delaware. The principal executive office of the Company is located at
12001 North Houston Rosslyn, Houston, Texas 77086, and the Company's telephone
number is (713) 447-8787.

                                  THE OFFERING

     This offering is made only to certain employees of the Company and its
subsidiaries for the purpose of providing such persons with the opportunity to
obtain an equity interest in the Company. The Company reserves the fight to
withdraw this offering and return all subscriptions or make non-material
modifications to the offering at any time during the term of the offering. All
Funds shall be promptly deposited in an interest bearing, segregated account and
such Funds may be invested in treasury bills or other cash equivalents, as
determined in the sole and absolute discretion of the Company. Funds deposited
in the segregated account may not be withdrawn by subscribers unless the
offering terminates as described herein. The deposit of Funds in such account
does not constitute acceptance of all or any portion of any offeree's
subscription by the Company.

General

     Subject to adjustment for over subscription, each offeree may subscribe to
purchase for cash as many of the Shares as such offeree may desire. Upon such
subscription, the Company will, at the request and option of each subscribing
offeree, loan (the "Four Year Loan") such subscribing offeree sufficient funds,
on a full recourse and secured basis, to purchase two additional Shares (all
such Shares hereinafter the "Loan Shares") for each Share subscribed for
hereunder for cash (the "Cash Shares"). See "- The Four Year Loan." For each
Share acquired by a subscribing offeree hereunder, the Company will grant such
subscribing offeree an option to purchase one-third of one share of Common Stock
pursuant to the terms of the 1995 Employee Stock Option Plan, substantially in
the form attached hereto as Exhibit (the "Employee Option Plan"). The exercise
price for such options will be $1,500 per share (subject to adjustment for stock
splits, stock dividends and other similar events as described in the Employee
Option Plan). See "-Options - Employee Option Plan."

     Offerees who desire to subscribe for Shares will be required to become
parties to the Amended and Restated Stockholders' Agreement of Hanover
Compressor Company attached hereto as Exhibit B (the "Stockholders' Agreement").
The Stockholders' Agreement restricts the sale of Common Stock held by the
parties thereto and provides for, among other things, (i) the right of Investors
(as hereinafter defined) to participate in a sale by GKH Partners, L.P., a
Delaware limited partnership ("Partners"), and GKH Investments, L.P., a Delaware
limited partnership (together with Partners, "GKH"), of at least 50% of the
Common Stock owned by GKH, (ii) the right of GKH to require all Investors to
sell their stock in certain transactions for the same consideration to be
received by GKH and (iii) the right of the Company or its affiliates to purchase
all of an Investor's Common Stock upon the termination of such Investor's
employment with the Company and its subsidiaries and affiliates. The purchase
price for such stock varies depending on the circumstances and, in cases where
an Investor is terminated for

                                       3
<PAGE>

cause or voluntarily terminates his employment without good reason (each as more
fully defined in the Stockholders' Agreement), such purchase price may be
substantially below the fair market value of such Common Stock. See "-
Stockholders' Agreement."

     The maximum aggregate number of shares which may be subscribed for pursuant
to this offering is 2,000, which number does not include any shares of Common
Stock to be issued upon exercise of options granted under the Employee Option
Plan. If the offerees; subscribe for more than such number of shares of Common
Stock, each offeree's subscription will be reduced proportionately based on the
relationship between the number of shares subscribed for by such offeree and the
aggregate number of shares subscribed for by all offerees.

     For information regarding the method of subscribing for Shares, see "Plan
of Offering" and the Subscription Agreement attached hereto as Exhibit A (the
"Subscription Agreement").

Suitability

     Investment in the Shares offered hereby involves a significant degree of
risk. See "Risk Factors." This offering is a private offering made only by
delivery of a copy of this Offering Memorandum to employee of the Company or its
subsidiaries whose name appears hereon. The Shares have not been registered
under the Securities Act, or any applicable state securities laws. The Shares
are being offered pursuant to one or more exemptions from the registration
requirements of the Securities Act, including the exemption afforded by Section
4(2) thereof, Regulation D and/or Section 701 promulgated thereunder, and
pursuant to available exemptions under state securities laws, only to certain
employees for investment only. Each person who subscribes for Shares and whose
subscription is accepted by the Company (each an "Investor," collectively, the
"Investors") will be required to represent that he is acquiring the Shares for
his own account, for investment, and without any intention of making a
distribution or resale thereof, either in whole or in part. The Shares may not
be resold or transferred except in accordance with the provisions of the
Securities Act, the rules and regulations thereunder, any applicable state
securities laws and the terms and conditions of the Stockholders' Agreement. As
a result of the foregoing, investment in the Shares is suitable only for persons
of adequate financial means apart from their investment in the Shares, and who
have no need for liquidity with respect to such investment.

     Offerees who desire to subscribe for Shares should read and discuss with
their advisors this Offering Memorandum, the Subscription Agreement, the
Stockholders' Agreement, the Loan Agreement (as defined below), the Four Year
Note (as defined below), the Pledge Agreement (as defined below), the Employee
Option Plan and the other documents relative to the foregoing regarding the
appropriateness of an investment in the Shares. The desirability of an
investment in the Common Stock depends upon a number of factors including, among
others, (i) the factors set forth under the caption "Risk Factors," (ii) the
nature of the Company's business, (iii) the possibility of a decline in value of
the Common Stock, (iv) the various restrictions on transferability of the Common
Stock, including those contained in the Stockholders' Agreement, and the present
essential illiquidity of the investment, (v) the desirability to the offeree of
a long-term investment, (vi) the likelihood that the Company will not pay
dividends on the

                                       4
<PAGE>

Common Stock in the foreseeable future and the likelihood of restrictions
imposed on the Company's ability to pay dividends under the terms of the
agreements governing the Company's senior secured indebtedness and the
Additional Issuances (as defined below), (vii) the control of the Company by its
principal stockholders, (viii) the relationship between such offeree's
investment (including the investment pursuant to the Four Year Loan) and such
offerees' net worth, (ix) the employment goals of the offeree and the right of
the Company to purchase such offeree's Common Stock upon the termination of his
employment with the Company, in some instances at a purchase price equal to or
less than the offeree's cost thereof, even if such cost is less than the fair
market value of such Common Stock, and (x) other relevant personal circumstances
of each offeree.

The Four Year Loan

     Each Investor may, but is not required to, request from the Company a Four
Year Loan to purchase the Loan Shares. Inasmuch as the Four Year Loan will be
made on a full recourse and secured basis, each Investor should consider
carefully the additional risk that he or she will undertake by obtaining the
Four Year Loan to purchase Shares.

     The Four Year Loan will bear interest at the prime rate as announced from
time to time by Chemical Bank ("Prime Rate"), will be made pursuant to a loan
agreement substantially in the form of Exhibit C hereto (the "Loan Agreement"),
evidenced by a secured promissory note substantially in the form of Exhibit D
hereto (the "Four Year Note"). Any amount of principal and/or accrued interest
on the Four Year Note which is not paid when due will bear interest at the Prime
Rate plus 2%, except that upon the failure to make the required payments
following (i) the sale of Common Stock or receipt by the Investor of dividends
on Common Stock, (ii) termination for Cause (as defined below) and (iii)
voluntary termination without Good Reason (as defined below), the outstanding
principal and accrued and unpaid interest will bear interest at 15% per annum,
compounded monthly, or the highest rate of interest allowable under applicable
law, whichever is less. Interest on the Four Year Note will be payable in cash
annually on December 31 (each an "Interest Payment Date") to the extent of 66.7%
of the accrued interest to such date (the "Minimum Interest Payment"), and all
accrued interest which is not paid as of an Interest Payment Date will be
automatically added to the principal amount of the Four Year Note. Each Minimum
Interest Payment must be paid to the extent of bonus payments, if any, less an
allowance equal to 33.3% of such bonus payment for federal and state income tax
(the "Net Bonus"), paid to the Investor by the Company on or before each
Interest Payment Date (including amounts paid in such calendar year which relate
to a previous calendar year and were not taken into consideration in such prior
calendar year), provided that nothing herein or in the Loan Agreement or the
Four Year Note shall create any obligation on the part of the Company to pay any
bonus. In the event the Net Bonus is insufficient to pay the Minimum Interest
Payment, the Investor shall be required to pay the difference between such Net
Bonus and the Minimum Interest Payment. The Company will have the right to
withhold from the Investor all or any portion of a Net Bonus payable by the
Investor in respect of interest under the Four Year Loan, which amounts will be
deemed to have been paid to the Investor and subsequently repaid by the Investor
to the Company. All principal and accrued and unpaid interest will be due upon
maturity, which will be 48 months from the date of the Loan Agreement, provided
that such date

                                       5
<PAGE>

may be accelerated upon the occurrence of an Event of Default (as defined below)
or under other circumstances more fully described in the Loan Agreement and the
Four Year Note.

     The Four Year Note will be secured by a pledge of (i) all of the shares and
rights to acquire shares of Common Stock owned by the Investor as of the date of
the Four Year Loan, or which are acquired by the Investor subsequent to the date
of the Four Year Loan and (ii) all proceeds received by an Investor thereon,
including dividends and additional shares received in stock distributions, all
as more fully set forth in the pledge agreement attached hereto as Exhibit E
(the "Pledge Agreement"). The Four Year Note will provide for mandatory
prepayment upon and to the extent of dividends or other distributions paid to
the Investor on the Common Stock and proceeds from the sale of the Common Stock,
and upon termination of the Investor's employment by the Investor without Good
Reason (as defined below) or by the Company for Cause (as defined below).

     The Four Year Note, the Loan Agreement, the Pledge Agreement and any other
documents that are executed in connection therewith (collectively, the "Loan
Documents") will be assignable by the

     Company to any of its affiliates, including GKH, or to any third party
financial institution or commercial lender to which the Company is or becomes
indebted. The Loan Documents cannot be assigned by an Investor without the
Company's prior written consent.

     "Cause," when capitalized and with reference to the termination of the
Investor's employment with the Company, means (i) the commission of an act of
fraud, embezzlement or willful breach of a fiduciary duty to the Company
(including the unauthorized disclosure of confidential or proprietary material
information of the Company), (ii) a conviction (or a plea of nolo contendere in
lieu thereof) for a felony or a crime involving fraud, dishonesty or moral
turpitude, (iii) willful misconduct as an employee of the Company, (iv) the
willful failure to render services to the Company in accordance with such
Investor's employment, which failure amounts to a material neglect of his duties
to the Company or (v) substantial dependence, as determined by the Board of
Directors of the Company (the "Board"), on alcohol or any controlled substance.

     "Good Reason," when capitalized, means, with reference to the voluntary
termination of the Investor's employment with the Company by the Investor, where
such termination (i) promptly follows a material reduction of such Investor's
duties and responsibilities or a permanent change in such Investor's duties and
responsibilities which are materially inconsistent with the type of duties and
responsibilities of such Investor then in effect, (ii) promptly follows a
material reduction in annual base salary (without regard to bonus compensation,
if any), (iii) promptly follows a material reduction in such Investor's employee
benefits (without regard to bonus compensation, if any) if such reduction
results in such Investor receiving benefits which are, in the aggregate,
materially less than the benefits received by other comparable employees of the
Company generally or (iv) the Board otherwise determines that a voluntary
termination by such Investor is for "Good Reason" under the circumstances then
prevailing.

                                       6
<PAGE>

     An "Event of Default". when capitalized and with reference to the Four Year
Loan includes, without limitation, (i) the failure to pay principal or interest
when due, which failure has continued for 10 days after written notice from the
Company, (ii) any representation or warranty contained in the Loan Documents or
the Subscription Agreement being incorrect in any material respect on or as of
the date made or deemed made, (iii) the default with respect to any covenant
contained in the Loan Documents, which default is not curable by the Investor
or, if curable, has continued uncured for 10 days after written notice from the
Company, (iv) the failure of the Investor to make any payment when due under, or
other default of the Investor which permits acceleration of, any other material
indebtedness of the Investor and (v) the occurrence of certain bankruptcy-
related events with respect to the Investor which continue for 60 days or are
otherwise consented to by the Investor.

Options

Employee Option Plan

     For each share of Common Stock acquired by an Investor hereunder, the
Company will grant such Investor an option to purchase one-third of one share of
Common Stock (subject to adjustment for stock splits, stock dividends and other
similar events as described in the Employee Option Plan) at a purchase price of
$1,500 per share. Such options will vest ratably over a five year period
beginning on the first anniversary of the Employee Option Plan (subject to (i)
acceleration upon termination of employment due to death or permanent disability
and upon the occurrence of a Capital Event (as defined in the Employee Option
Plan) and (ii) forfeiture upon termination for Cause) and be governed by the
terms of the Employee Option Plan and individual option agreements (the
"Employee Option Agreements") between the Company and each Investor, forms of
which are attached hereto as Exhibits F and G, respectively. The term of the
options will be 10 years, subject to a limited exercise period for vested
options in the event of the termination of employment of the Investor (other
than for Cause). An option may not be exercised during any period in which the
Investor is in default under the terms of any loan or other obligation that the
Investor may have to the Company. The shares of Common Stock acquired upon
exercise of the options will be subject to the terms of the Stockholders'
Agreement. Options may not be transferred other than by will or the laws of
descent and distribution, and during the lifetime of an Investor, such options
may be exercised only by the Investor. The options granted under the Employee
Option Plan are nonstatutory options and are not intended to qualify as
"incentive stock options" under Section 422 of the Internal Revenue Code of
1986, as amended (the "Code"), and each Investor should consult his tax advisors
for information regarding the tax treatment of such options.

     Pursuant to the Employee Option Agreements, each Investor will agree that
he will not during the term of such agreement and for a period of one year
thereafter, (i) compete with any business of the Company or its subsidiaries or
affiliates and (ii) without the Company's express written consent, disclose to
persons outside the Company confidential information concerning the Company or
any of its subsidiaries or affiliates.

Stockholders' Agreement

     As a condition to the acceptance by the Company of a subscribing offeree's
subscription for Shares, such subscribing offeree is required to become a party
to the Stockholders' Agreement. The summary of the Stockholders' Agreement set
forth below is not intended to be a complete recitation of the provisions
thereof, and each offeree should read and understand all the provisions of the
Stockholders' Agreement before making a determination whether to invest in the
Shares.

Restrictions on Transfer

     The Stockholders' Agreement contains substantial restrictions on the
disposition of an Investor's Common Stock. In general, an Investor will be
permitted to transfer some or all shares of his Common Stock to affiliates,
including certain relatives and controlled entities, provided each affiliate
agrees to be bound by the terms of the Stockholders' Agreement. An Investor will
also be permitted to transfer all (but not less than all) of his shares of
Common Stock to a bona fide third party purchaser if such purchaser agrees to be
bound by the terms of the Stockholders' Agreement, but only after such Common
Stock is offered first to the Company and then to GKH on the same terms as
offered to the bona fide third party purchaser. The Investor will be required to
comply with certain mechanical provisions regarding such transfer, including (i)
timely notice to the Company and GKH of any proposed transfer and (ii)
consummation of any transfer within a specified period.

Rights to Compel Disposition

     GKH will have the right to compel each Investor to dispose of all of his
shares of Common Stock and make certain representations with respect to his
ownership of such Common Stock in the event GKH seeks to transfer all, but not
less than all, of its Common Stock. If GKH exercises its right to compel the
disposition of the Investors' Common Stock, the consideration for such Common
Stock will be the same per share consideration on the same terms to be received
by GKH for its shares of Common Stock.

Rights of Inclusion

     Each Investor will have the right to sell his Common Stock on the same
terms as GKH in a transaction pursuant to which GKH sells at least 50% of the
outstanding Common Stock of the Company then owned by GKH. Investors who desire
to participate in such sale will be required to deliver notice on a timely basis
and comply with other mechanical provisions in connection with such transfer.

Preemptive Rights

     Although Delaware law does not generally provide for preemptive rights, in
the event the Company offers an existing stockholder who is party to the
Stockholders' Agreement the opportunity to purchase additional shares of Common
Stock, the other parties to the Stockholders' Agreement will have the right to
acquire their respective pro rata share of

                                       8
<PAGE>

such Common Stock on the same terms and conditions offered to such stockholder,
except that such right shall not apply to (i) shares issuable in connection with
a merger, acquisition or similar transaction, (ii) shares issuable upon the
exercise of any options, warrants or other convertible securities, (iii) shares
offered by the Company to employees and directors of the Company or (d) shares
issuable in connection with preemptive rights granted to other stockholders of
the Company in connection with a merger, acquisition or similar transaction, or
in connection with the issuance by the Company of its Series B Preferred Stock
(as defined below).

Transfers upon Termination

     The Company will have the right to purchase all of the Common Stock of an
Investor in the event such Investor ceases to be an employee of the Company or
any of its subsidiaries or affiliates. The purchase price for such Common Stock
will be (i) in the event such Investor's employment is terminated for Cause, the
lower of the Investor's cost for his Common Stock on a share by share basis and
80% of fair market value thereof, (ii) in the event such employment is
voluntarily terminated without Good Reason, the lower of cost and fair market
value and (iii) in the event such Investor's employment is terminated by death,
retirement, permanent disability, without Cause or voluntarily with Good Reason,
the fair market value of such Common Stock. The purchase price for such Common
Stock will be payable (a) in cash (and/or by the delivery of a term note with
the shortest term permissible if required by any agreement to which the Company
is then subject) if such Investor's employment is terminated with Good Reason or
upon death, retirement, permanent disability or without Cause, or voluntarily
without Good Reason more than three years after the date of the Stockholders'
Agreement, and (b) by delivery of a seven year term note if such employment is
terminated for Cause, or voluntarily without Good Reason on or prior to the
third anniversary of the Stockholders' Agreement. Any note delivered in
connection with the foregoing will bear interest, payable annually, at the Prime
Rate.

     Cost, fair market value, retirement, permanent disability and voluntary
termination are each defined in the Stockholders' Agreement.

                        FEDERAL INCOME TAX CONSEQUENCES

     THE DISCUSSION SET FORTH BELOW PROVIDES GENERAL INFORMATION AS TO CERTAIN
ANTICIPATED FEDERAL INCOME TAX CONSEQUENCES ASSOCIATED WITH SUBSCRIPTION FOR THE
SHARES AND OPTIONS HEREUNDER. EACH INVESTOR SHOULD CONSULT HIS TAX ADVISOR AS TO
THE SPECIFIC TAX CONSEQUENCES OF I-US SUBSCRIPTION, INCLUDING THE APPLICATION OF
POSSIBLE OF STATE AND LOCAL TAX LAWS.

Restricted Stock

     Code Section 83 governs transfers of property to persons (whether employees
or independent contractors) in exchange for services. Under that section, a
person receiving property as compensation for services must report (as
compensation income) the excess of the fair market value of the property
received over the amount paid in exchange therefor (such excess referred to
herein as "In-Kind Compensation").

                                       9
<PAGE>

     In determining when a recipient of In-Kind Compensation must report income
attributable thereto, Code Section 83(a) provides that the value of such In-Kind
Compensation (without regard to any restriction other than a restriction which
by its terms will never lapse) is includible in the recipient's income at the
first time that the recipient's rights in the property are substantially vested.
For such purposes, property is considered to be substantially vested when it is
either (a) transferable or (b) not subject to a substantial risk of forfeiture.
A substantial risk of forfeiture is generally considered to exist when the
recipient's rights to the property are predicated upon the future performance of
services or upon the occurrence of a condition related to the transfer. Further,
an interest in restricted property is transferable only if the subsequent
transferee's rights in the property are not subject to a substantial risk of
forfeiture.

     Alternatively, Code Section 83(b) provides each recipient of In-Kind
Compensation the ability to include such amounts in income in the year in which
he receives them, rather than the year in which the In-Kind Compensation becomes
substantially vested. Under that section, a taxpayer may elect, within 30 days
of the transfer of property, to include in income the value of any In-Kind
Compensation (as determined without regard to the restrictions thereon).
Taxpayers who include In-Kind Compensation in income under Code Section 83(b)
but later forfeit the property received are denied a deduction for any portion
of the In-Kind Compensation reported by the taxpayer.

     Once includible in the income of the recipient, In-Kind Compensation is
considered payment of wages subject to withholding of income tax and deposits
pursuant to the Federal Insurance Contributions Act (FICA). Upon the subsequent
sale of the transferred stock or other property, the taxpayer will recognize
income to the extent that the amounts realized on sale exceed the sum of (a) the
amount includible in his income under Code Section 83 and (b) the amount paid
for the property.

     Offerees who desire to subscribe for Shares will be required to become
parties to the Stockholders' Agreement. Pursuant to the Stockholders' Agreement,
each Investor may be required, in the event his employment terminates for Cause
or without Good Reason, to sell his Shares back to the Company for an amount
equal to the lower of (a) cost or (b) a percentage (either 100% or 80%) of fair
market value. Any transferee of an Investor may be required to sell the
transferred Shares to the Company upon similar terms in the event that the
Investor's employment is terminated for Cause or without Good Reason. Such
restrictions lapse with respect to any Investor on the earliest to occur of (a)
the Investor's death, retirement, permanent disability, or involuntary
termination of employment without Cause, (b) the Investor's voluntary
termination of employment with G&A Reason, or (c) the failure of the Company to
exercise its rights to purchase the Investor's Shares in a timely fashion
following the termination of his employment for Cause or without Good Reason
(each such event referred to as a "Lapse Event"). See "The Offering -
Stockholders' Agreement."

     The Company believes that, in light of various provisions of the
Stockholders' Agreement, each Investor subscribing for Shares hereunder will
acquire such Shares subject to a substantial risk of forfeiture. Further, the
Company believes that the Shares subscribed for hereunder are not transferable
within the meaning of Code Section 83. As such, to the extent that

                                      10
<PAGE>

the fair market value of any Share exceeds the amount paid therefor, no Investor
should be required to include in income the In-Kind Compensation attributable
thereto until the restrictions lapse at the occurrence of a Lapse Event.
Nevertheless, any Investor may elect, under Code Section 83(b), to include the
value of the In-Kind Compensation in the year in which he purchases Shares
pursuant to this Offering.

Stock Options

     Taxpayers receiving compensatory, nonstatutory stock options (i.e., options
other than "qualified options" taxable under Code Section 421) generally do not
recognize income as a result of the grant of such options. Unless the granted
options have a readily ascertainable fair market value within the meaning of
Code Section 83 as of the date of grant, the taxpayer realizes income only on
the date he exercises or disposes of such options. At that time, he realizes
compensation income equal to the difference between the market value of the
stock and the price paid to acquire and exercise the option. However, where the
optionee's rights in the property transferred pursuant to the exercise of such
option are not substantially vested (within the meaning of Code Section 83), the
optionee does not realize income until the first time that his rights in that
property become substantially vested. See "- Restricted Stock."

     When an option is not regularly traded on an established market, it does
not have a readily ascertainable market value unless its value can be determined
with "reasonable accuracy." For such purposes, the value of an option cannot be
determined with reasonable accuracy unless all of the following conditions
exist:

          (i)   The option is transferable;

          (ii)  The option is exercisable immediately in full;

          (iii) The option is not subject to any restriction or condition which
                has a significant effect upon its value; and

          (iv)  The value of the option privilege is readily ascertainable.

     For each Share Stock acquired by an Investor hereunder, the Company will
grant such Investor an option to purchase one-third of one share of Common Stock
(subject to certain adjustments) at a purchase price of $1,500 per share. Such
options will vest ratably over a five-year period commencing on the first
anniversary of the Employee Option Plan, will be nontransferable (except by will
or the laws of descent and distribution) and, during the life of the Investor,
may be exercised solely by the Investor. See "The Offering - Options - Employee
Option Plan." Once exercised, the shares of Common Stock acquired pursuant to
such exercise will become subject to the Stockholders' Agreement, including its
restrictions and repurchase rights vested in the Company. The options will not
be actively traded on an established market as of the date the Company grants
them.

     The Company believes that, since the options are neither exercisable
immediately in full nor transferable (except at death), the value of options may
not be determined with reasonable

                                      11
<PAGE>

accuracy. As the options should not have a readily ascertainable market value
within the meaning of Code Section 83, the Company believes that they should not
be compensation income to the optionee on the date of grant (notwithstanding
that their value may later become readily ascertainable). Further, since the
property acquired pursuant to the exercise of such options (i.e., shares of
Common Stock) will be subject to the Stockholders' Agreement, the Company
believes that an Investor exercising an option granted hereunder will acquire
property in which his rights are not substantially vested within the meaning of
Code Section 83. Accordingly, the Company believes that an Investor should not
have compensation income until the date that the restrictions on the Common
Stock acquired pursuant to such exercise lapse (i.e., at the occurrence of a
Lapse Event under the Stockholders' Agreement). At that time, the Investor
should recognize compensation income in an amount equal to the excess of the
market value of the stock as of such date over the price paid to exercise and
acquire the applicable option. Any Investor may, however, choose to accelerate
the recognition of income to the date he exercises an option provided he makes
the election under Code Section 83(b).

                                  RISK FACTORS

     Investors should consider the specifications set forth below as well as the
other information set forth in this Offering Memorandum.  The following is not
necessarily a comprehensive list of all of the possible risk factors associated
with an investment in the Common Stock.

Limited Operating History

     The Company's products are well-established in the marketplace, and the
Company has experienced net profits in three of its four full fiscal years of
operation. However, there can be no assurance that the Company will remain
profitable in the future. See "Management's Discussion and Analysis of Financial
Condition and Results of Operations."

Short Lease Terms; Possible Inability to Re-lease Compressors

     The Company has historically leased its compressors under leases with an
average fixed term of six months and which continue thereafter on a month to
month basis. Historically, lessees have renewed their leases on a month to month
basis for an average period of 24 months. Based on the average cost of new
compressors and the average lease price, the Company generally does not recoup
its investment in the compressors until after its receipt of at least 48 months
of lease payments. Accordingly, the Company assumes substantial risk of not
recovering its entire investment in the equipment it purchases. Although the
Company has historically been successful in re-leasing units in its inventory,
there can be no assurance that the Company will continue to be able to do so or
that a substantial portion of its lessees will not terminate their leases at
approximately the same time, thereby causing an adverse accumulation of unleased
compressors in the Company's inventory. The inability of the Company to lease a
substantial portion of its compressors for any reason would have a material
adverse effect upon the Company's financial condition and its results of
operations. See "Business."

                                      12
<PAGE>

Competition

     The natural gas compression industry and the oil and gas production
equipment business are highly competitive. The Company competes with several
large national and international companies which, like the Company, offer a wide
range of compressors and production equipment for purchase or lease. There can
be no assurance that such competitors will not substantially increase the
resources devoted to the development and marketing of products competitive with
those of the Company or that new competitors will not enter the industry. See
"Business - Competition."

Natural Gas Compressor Industry Considerations

     The Company's profitability is, in part, dependent upon the current demand
for natural gas. Natural gas demand, aided by competitive pricing and interstate
pipeline deregulation, has increased at a rate of approximately 2% per year from
1986 through 1994. The Company's management estimates that demand for Gas
compression has increased approximately 10% per year during this time frame.
This increase is a result of increased production from lower reservoir-pressured
areas and the increased amount of coal-seam and tight-gas drilling in certain
geographic areas.

     Depressed natural gas prices tend to decrease efforts to discover and
develop new natural gas reserves domestically. This places greater reliance upon
older, developed reserves which requires additional compression to deliver the
remaining natural gas to market. A significant decline in the price of natural
gas could result in the widespread failure of independent producers and
increased pricing pressure for compressor rental companies. This would have a
material adverse effect on the Company's financial condition and results of
operations. See "Business."

Potential Liability and Insurance

     Natural gas operations are subject to certain risks, including explosions,
uncontrollable flows of gas or well fluids, fires, pollution and other
environmental risks. These risks could expose the Company to substantial
liability for injury and loss of life, property damage, pollution and other
environmental damages, and consequential damages, if such damages resulted from
an alleged compressor defect or from the Company's negligence in maintaining,
servicing or refurbishing its compressors. Although the Company has obtained
certain insurance, no assurance can be given that such insurance is adequate to
cover the Company's operations, will be generally available in the future or, if
available, that premiums will be commercially justifiable. If the Company were
to incur a substantial liability and such damages were not covered by insurance
or were in excess of policy limits, or if the Company were to incur such
liability at a time when it is no longer able to obtain liability insurance, its
financial condition could be materially adversely affected. The Company,
consistent with industry trends, may find it difficult to obtain adequate
insurance coverage against possible liabilities that may be incurred in
connection with the conduct of its business. There can be no assurance that all
possible types of liabilities that may be incurred by the Company will be
covered by its insurance or that the dollar amount of such liabilities will not
exceed the Company's policy limits. A partially or

                                      13
<PAGE>

completely uninsured claim, if successful and of sufficient magnitude, could
have a material adverse effect on the Company and its financial condition.

Environmental Liability Risks

     In addition to liability which may arise as a result of an alleged
compressor defect or alleged Company negligence, if environmental damage is
found to have occurred as a result of the Company's operating activities, the
Company could incur substantial liability. In such event, the Company could be
liable for all costs of remediation, as well as certain other costs. Under the
Comprehensive Response, Compensation and Liability Act ("CERCLA"), the Company
may also be liable for all costs of remediation of any property of which it is
deemed to be the owner or operator. Various Preliminary Environmental (Phase I)
Site Assessments were conducted in 1990 and 1991 with respect to certain
properties owned or operated by the Company and its subsidiaries. Such
assessments identified potential sources of ground contamination. Although
remediation efforts have been undertaken by the previous owners, no assurances
can be given that such remediation efforts will be successful or that the
Company will not incur costs in remediating such contamination or discover
additional sources of enumerated contamination. In addition, pursuant to the HPC
Merger (as defined below), the Company acquired certain potential environmental
liabilities estimated at December 31, 1992 to be between $139,000 and $200,000.
See "Business - Company History" for a description of the HPC Merger.

     In June 1993, a Phase I and Phase II Environmental Assessment was conducted
on the Company's 20 acre headquarters/fabrication facility in Houston, which
Assessment indicated that such site has minimal apparent risk with respect to
environmental liability. In addition, the company maintains a professionally
designed Spill Prevention Control and Countermeasure Plan (the "SPCC Plan") with
respect to its Fort Smith, Arkansas maintenance facility, which is designed to
prevent oil spills and waste releases and to describe protocols for immediate
coordination of necessary activities to minimize any harmful effects should a
spill or other release occur. Although the Fort Smith facility does not
routinely generate hazardous waste, the SPCC Plan includes waste release
measures given that during an oil spill event, certain characteristic hazardous
waste from spill residue may be generated. Moreover, the Company is currently
implementing a Site Remediation and Clean Up Proposal regarding real property
located in Columbus, Texas with respect to which the Company acquired a lease
and purchase option pursuant to the February 1995 acquisition by the Company of
substantially all of the assets of Smith Industries, Incorporated. See "Business
- Company History."

Governmental Regulation

     The Company is subject to various federal, state and local laws and
regulatory standards in the areas of safety, health and the environment,
including regulations regarding emission controls. The Company believes that it
is in substantial compliance with such laws and regulations and that the phasing
in of emission controls and other known standards at the rate currently
contemplated by such laws and regulations will not have a material adverse
effect on the Company's financial condition or results of operations. However,
various state and federal agencies from time to time consider adopting new laws
and regulations or amending existing

                                      14
<PAGE>

laws and regulations regarding environmental protection. While the Company may
be able to pass on the additional costs of complying with such laws, there can
be no assurances that attempts to do so would be successful. Accordingly, new
laws or regulations or amendments to existing laws or regulations could require
the Company to undertake significant capital expenditures and could otherwise
have a material adverse effect on the Company's financial condition and results
of operations.

Restrictions Imposed by the Terms of the Company's Indebtedness; Effect of
Default

     The terms of the Company's existing credit agreement dated June 29, 1993,
as amended (the "Credit Agreement") among the Company, Chemical Bank, as agent,
and the other banks party thereto impose a variety of restrictions on the
Company's operations, including, without limitation, limiting the Company's
ability to incur additional indebtedness, grant or suffer liens or other
encumbrances on its property, make investments, loans or advances except under
certain enumerated circumstances, make capital expenditures above specified
levels, enter into sale/leaseback arrangements as a seller/lessee, dispose of
its assets or extend guarantees. Such restrictions may limit the Company's
ability to exploit fully certain business opportunities. In addition, under the
terms of the Credit Agreement, the Company may not declare or pay any dividend
or make any payment for the purchase, redemption or acquisition of any shares of
Common Stock other dun repurchases of Common Stock from employees of the Company
which do not exceed an aggregate of $1,500,000. In addition. the failure of the
Company to maintain certain financial ratios may cause the Company to be in
default under the agreements governing its indebtedness and such default, if
uncured, may ultimately entitle its creditors to foreclose on all of the assets
of the Company. See "Description of Certain Indebtedness."

Dependence on Internally Generated Funds; Capital Needs

     The compressor leasing business and the oil and gas production equipment
business in which the Company is involved are capital intensive businesses, and
the inability of the Company to continue to have access to sufficient capital
could have a material adverse effect on the Company's ability to finance
compressor purchases and production equipment materials purchases arid, thus,
maintain its future leasing revenues and profitability. Company growth has
historically been financed through (i) sales of Common Stock, including the sale
of approximately $15,000,000 of Common Stock to certain executive officers and
then existing stockholders of the Company in 1992 (the "1992 Offering"), the
sale of approximately $2,500,000 of Common Stock to certain members of the
Company's management in 1993 (the "1993 Offering"), the sale of approximately
$16,000,000 of Common Stock to GKH in 1993 and the sale of $275,000 of Common
Stock to certain employees of the Company in July 1995 (the "1995 Management
Offering"), (ii) internally generated funds and (iii) borrowings under the
Credit Agreement, which provides for a revolving credit facility with a
commitment of $35,000,000 and three term loans in the original principal amounts
of $15,000,000 (the "Original Term Loan"), $10,000,000 (the "B Tranche Loan")
and $4,000,000 (the "C Tranche Loan"), respectively. In addition, on June 6,
1995, the Company borrowed $12,000,000 (the "Subordinated Loan") from GKH and an
affiliate of certain existing stockholders of the Company pursuant to the terms
of a Subordinated Loan Agreement (the "Subordinated Loan
                                      15
<PAGE>

Agreement"). The Subordinated Loan is, by its terms, subordinate and junior in
right of payment to the obligations of the Company under the Credit Agreement.

     It is currently contemplated that at or about the time of this offering,
the Company will (i) issue new equity most likely in the form of (a) shares of
6.5% Cumulative Redeemable Series A Preferred Stock along with warrants to
purchase new shares of Common Stock and (b) shares of Common Stock and 6.5 %
Cumulative Redeemable Convertible Series B Preferred Stock to certain third-
party investors (the transactions described in (a) and (b) above, hereinafter
the "Additional Issuances") and (ii) enter into an agreement regarding a
$100,000,000 stand-by long term credit facility. See "Certain Contemplated
Transactions". However, the consummation of such transactions are not a
condition to the consummation of this offering and there can be no assurance
that any or all of such transactions will be consummated.

     In addition, although the Company believes that it will have sufficient
capital resources based on internally generated funds, the amounts available
under the Credit Agreement and the Subordinated Loan, the proceeds of the
Additional Issuances and other proposed private placements of equity to fund its
anticipated capital needs for at least the next 5 years, there can be no
assurance that the Company will meet its projected earnings and that sufficient
cash flow will be generated. Failure to generate sufficient cash flow together
with the absence of alternative sources of capital could have a material adverse
effect on the financial condition, operations and expected growth of the
Company. See "Management's Discussion of and Analysis of Financial Condition and
Results of Operations."

Limited Preemptive Rights

     Although Delaware law does not generally provide for preemptive rights, in
the event the Company offers any party to the Stockholders' Agreement the
opportunity to purchase additional shares of Common Stock, all other parties to
the Stockholders' Agreement will have the right to acquire their respective pro
rata share of such Common Stock on the same terms and conditions offered to such
other stockholder, except that such right shall not apply to (i) shares issuable
in connection with a merger, acquisition or similar transaction, (ii) shares
issuable upon the exercise of any options, warrants or other convertible
securities or (iii) shares offered by the Company to employees of the Company.
See "The Offering - Stockholders' Agreement - Preemptive Rights" and
"Description of Capital Stock."

     Similarly, subject to these same exceptions, the parties to the 1993
Stockholders' Agreement and the 1995 Management Stockholders' Agreement (each as
defined below) would have the right to purchase a pro rata amount of Common
Stock if the Company were to offer any party to either respective Stockholders'
Agreement the right to purchase additional shares of Common Stock. In addition,
in the event the Company sells or otherwise issues any shares of Common Stock to
GKH, the non-GKH parties to the Gale Force Stockholders' Agreement (as defined
below) will have the right to acquire their respective pro rata amount of Common
Stock on the same terms and conditions as such Common Stock is sold or otherwise
issued to GKH. See "Principal Stockholders - Stockholders' Agreements - 1993
Stockholders' Agreement," "-- Gale Force Stockholders' Agreement;" and "- 1995
Management Stockholders' Agreement."

                                      16

No Public Market for Common Stock; Restriction on Transferability

     Each subscribing offeree will be required to represent that he is
purchasing the Shares for investment purposes for his own account but not with a
view to resale or distribution. There is no public market for the Shares, and an
Investor's ability to transfer his Common Stock will be significantly restricted
by the terms of the Stockholders' Agreement. In addition, the Stockholders'
Agreement (i) gives GKH the right to cause all Investors to sell their Common
Stock in certain transactions and (ii) gives the Company or certain of its
affiliates the right, but not the obligation, to purchase all of the Common
Stock of an Investor upon the termination of such Investor's employment with the
Company. The purchase price for such stock varies depending on the circumstances
and, in cases where an Investor is terminated for Cause or voluntarily
terminates his employment without Good Reason, such purchase price may be
substantially below the fair market value of such Common Stock. See "The
Offering -Stockholders' Agreement." Any potential Investor must be able and
willing to bear the risk of his investment for an indefinite period.

Dividends

     The Company has never paid cash dividends on its Common Stock and does not
anticipate paying any cash dividends in the foreseeable future. In addition, the
ability of the Company to pay dividends will be limited by the terms of the
Credit Agreement, the Subordinated Loan Agreement and the contemplated Stand-by
Credit Facility, Series B Preferred Stock Issuance and Series A Preferred Stock
Issuance. See "Description of Certain Indebtedness," and "Certain Contemplated
Transactions."

Control by Principal Stockholders

     Prior to the consummation of this offering, approximately 79% of the
Company's outstanding Common Stock (not including shares issuable pursuant to
existing option programs) was owned by GKH. Subsequent to this offering, GKH
will continue to own a majority of the Common Stock of the Company. By
maintaining such majority ownership, GKH will continue to have the power to
determine the policies of the Company and its subsidiaries, the persons
constituting the directors and officers thereof (subject to the terms of (i) the
1993 Stockholders' Agreement, (ii) the Gale Force Stockholders' Agreement, (iii)
the Hanna Stockholders' Agreement, (iv) the HEHC Stockholders' Agreement, (v)
the 1995 Management Stockholders' Agreement and (vi) the Stockholders'
Agreement) and the outcome of various corporate actions requiring stockholder
approval (subject to the terms of the HEHC Stockholders' Agreement). See
"Principal Stockholders - Stockholders' Agreements" for a description of these
agreements.

Recent Expansion Activity

     Through its acquisition of the production equipment business of Smith
Industries, Incorporated (the "Smith Business;" See "Business - Company
History"), the Company substantially expanded its oil and gas production
equipment fabrication operations. The Company is now in the process of
integrating the Smith Business into its current operations. Given the size of
this acquisition, there can be no assurance that the integration will be
successful

                                      17
<PAGE>

or that additional capital will not be required to operate the Company's oil and
gas production equipment business. In addition, the Company has also made
certain other acquisitions, which management believes will enhance the Company's
competitive position in the natural gas compression industry, which is generally
experiencing a considerable amount of consolidation. See "Business - Company
History." However, there can be no assurance that such acquisitions will bring
the desired results.

Dilution

     Assuming all of the Shares are issued, the value of the Shares purchased
pursuant to this offering will be subject to immediate dilution in the net
tangible book value of $455.55 per Share from the adjusted net tangible book
value as of March 31, 1995.

Federal Income Tax Risks

     The following discussion summarizes certain federal income tax risks
associated with an investment in the Shares and the exercise of options acquired
therewith, and should be read in conjunction with "Federal Income Tax
Consequences." As the following does not purport to be a complete discussion of
all relevant tax issues, prospective investors should consult their own tax
advisors for advice regarding the impact of a subscription for Shares and
options upon their individual tax positions, including the application of state
and local income tax law, if any.

Treatment of Compensation Income; Receipt of Shares

     No assurance can be given that the Internal Revenue Service ("IRS") will
consider the provisions of the Stockholders' Agreement to be sufficient to
render Shares subscribed for hereunder to be nontransferable and each Investor's
rights therein to be subject to a substantial risk of forfeiture within the
meaning of Code Section 83. Further, no assurance can be given that a court of
competent jurisdiction would agree with the conclusions of the Company. In the
event that the IRS considers the provisions of the Stockholders' Agreement to be
insufficient for such purpose, it will consider each Investor to have
compensation income (as of the date he acquires Shares) in an amount equal to
the difference between the fair market value of such Shares and the Investor's
purchase price. Each Investor may thus be required to pay federal income and
FICA tax on such income, plus interest and penalties as applicable. Further, the
Company may be required to pay federal unemployment and other taxes on the
compensation deemed to be transferred to each Investor, plus interest and
penalties as applicable, which tax may indirectly effect the value of each
Investor's Shares.

Treatment of Compensation income; Receipt of Options

     No assurance can be given that the IRS (or any court) will agree that an
Investor acquiring Common Stock pursuant to the exercise of any option is
subject to a substantial risk of forfeiture with respect to such Stock and such
Stock is nontransferable under Section 83 of the Code. As such, an Investor
exercising options granted hereunder may realize compensation income at the date
he exercises an option in an amount equal to the difference between the fair
market value of the Common Stock on that date over the price paid to exercise
and acquire the

                                      18
<PAGE>

applicable option. An Investor may thus be required to pay federal income and
FICA tax (and interest and penalties, as applicable) with respect to such
compensation income. Similarly, the Company may be required to pay federal
unemployment and other taxes (including penalties and interest) which payment
may indirectly effect the value of each Investor's Common Stock.

Election under Code Section 83(b)

     Any Investor may make an election to include amounts in income on the date
he acquires shares of Common Stock (whether at subscription for Shares or upon
the exercise of any option granted hereunder). Electing Investors will thus not
recognize additional compensation income upon the occurrence of a Lapse Event
under the Stockholders' Agreement. However, since each electing Investor
accelerates the recognition of income from the time at which the Company
believes it would otherwise be first recognizable (i.e., the date of any Lapse
Event), each electing Investor must bear certain market risks associated with
the value of his Shares. If the value of an electing Investor's Shares does not
exceed the value of such Shares on the date that the Investor acquired them,
such electing Investor will have included amounts in income which would not have
otherwise have been includible had he not made the election under Code Section
83(b). Such electing Investor will not be entitled to deduct any amounts
attributable to that income acceleration.

     Further, in the event that an electing Investor is required to sell Shares
of Common Stock back to the Company (e.g., pursuant to the exercise of the
Company's rights to repurchase such Shares in the Stockholders' Agreement), that
Investor will not be allowed any deduction for any portion of the basis in such
Shares that he acquired as a result of a Section 83(b) election.

                       CERTAIN CONTEMPLATED TRANSACTIONS

     The following summary of the terms of certain contemplated transactions of
the Company is based on the anticipated terms thereof. The Company reserves the
right in its sole and absolute discretion without notice to or consent of any
Investor to accept changes to such anticipated terms, and to cancel any or all
of such transactions, without affecting this offering.

Enron Investment and Stand-by Credit Facility

     On June 26, 1995, the Company entered into a non-binding letter of
understanding with Enron Capital & Trade Resources Corp., a Delaware corporation
("Enron"), with respect to (a) the investment by Enron (and/or its affiliates or
designees which are acceptable to the Company) (each an "Enron Entity") in newly
issued shares of Common Stock and Preferred Stock for an aggregate purchase
price of $30,000,000 and (b) the commitment by an Enron Entity to make available
to the Company a $100,000,000 stand-by long term credit facility (the "Stand-by
Credit Facility").

     As currently contemplated, an Enron Entity will purchase $20,000,000 of
Common Stock at $1,800 per share and $ 10,000,000 of 6.5% Cumulative Redeemable
Convertible Series B Preferred Stock (the "Series B Preferred Stock") at $1,000
per share (the "Series B Preferred Stock Issuance"). Such Enron Entity would
hold its Common Stock and Series B Preferred Stock

                                      19
<PAGE>

subject to the terms of a stockholders' agreement containing terms substantially
similar to those contained in the Stockholders' Agreement, except that (i) until
the earlier to occur of the Company having satisfied all of its obligations to
the Enron Entity under the Stand-by Credit Facility and a public offering of the
Common Stock, the Enron Entity would have the right with respect to certain
equity offerings of the Company (each a "Rights Offering") (a) to subscribe for
the first fifteen percent of such Rights Offering on an exclusive basis, (b)
subscribe for its pro rata share of the remaining equity under the Rights
Offering and (c) cause its duly licensed affiliate to underwrite all of such
rights offering in the event the Enron Entity and the Company can mutually agree
on the terms of such underwriting, (ii) so long as the Enron Entity owns 7.5 %
of the outstanding Common Stock (on a fully diluted basis) and generally does
not hold an equity interest in a competitor of the Company, the Enron Entity
would have certain rights regarding notice of and attendance at meetings of the
Board or would have the right to elect one member of the Board and (iii) the
right of inclusion of the Non-GKH stockholders parties thereto would be
triggered only in the event that GKH proposes to sell all of its Common Stock
and Preferred Stock. In addition, the agreement would terminate upon the earlier
of certain events, including the consummation of a publicly registered offering
of 20% or more of the Common Stock or August 1, 2005.

     The 6.5 % per share per annum dividend on the Series B Preferred Stock
would be payable in additional shares of Series B Preferred Stock during the
initial three years after issuance, and in cash thereafter. The Series B
Preferred Stock would not be redeemable by the Company until (i) any "Redemption
Event" (e.g. sale of all of the Company's assets, a merger in which the Company
is not the surviving corporation or GKH not owning more than 50% of the
outstanding Common Stock) or (ii) the third anniversary of the initial issuance
thereof, and thereafter would be redeemable at a price which is based on the
initial purchase price and which would vary based on when such redemption
occurred. The Enron Entity would upon the occurrence of a Redemption Event have
the right to require the Company to redeem all or any portion of its Series B
Preferred Stock at $1,000 per share plus accrued but unpaid dividends thereon.
Following the third anniversary of the issuance of the Series B Preferred Stock
or upon a Redemption Event, the Enron Entity would be permitted to convert the
Series B Preferred Stock into shares of Common Stock at a conversion price equal
to the greater of (i) $2, 100 and (ii) the product of (A) 6.4 and (B) a per
share calculation of the Company's earnings before interest, taxes, depreciation
and amortization for a given period, less the Company's consolidated long term
debt and liquidation preference of the Preferred Stock (without premium) at a
given time. The conversion price of the Series B Preferred Stock is also subject
to standard anti-dilution adjustments. In addition, the holders of the Series B
Preferred Stock would have special voting rights along with the holders of the
Series A Preferred Stock (as defined below) with respect to certain enumerated
transactions.

     As presently contemplated, the Stand-by Credit Facility would permit long
term borrowings up to $100,000,000 in $10,000,000 minimum increments. It is
contemplated that absent default, up to $20,000,000 of the Stand-by Credit
Facility would be available to the Company for working capital purposes without
satisfaction of any financial tests and up to $80,000,000 would be available for
general corporate purposes, including acquisitions, but subject to satisfaction
of certain financial tests. The Standby Credit Facility would be secured

                                      20

pari passu with the Company's other Senior Lenders and is subject to a
---- -----
commitment fee ranging from 0.5% to 0.25% of undrawn amounts, as well as an
annual fee of $100,000.

Series A Preferred Stock Issuance

     It is currently anticipated that the Company will issue (the "Series A
Preferred Stock Issuance") shares of 6.5 % Cumulative Redeemable Series A
Preferred Stock (the "Series A Preferred Stock") in an aggregate amount which is
yet unspecified at $1,000 per share. Dividends on the Series A Preferred Stock
will be payable in additional shares of Series A Preferred Stock during the
initial three years after issuance, and in cash thereafter. The Series A
Preferred Stock would be redeemable by the Company and the holders thereof on
the same terms on which the Series B Preferred Stock may be redeemed. Each share
of Series A Preferred Stock will carry with it a detachable warrant to purchase
0. 1667 shares of Common Stock at $1.00 per share, which warrants will vest 20%
at the time of issuance and, thereafter, incrementally on a monthly basis over
the subsequent three years. Upon exercise of the warrants the holders of the
Common Stock underlying the warrants would have so-called "piggy-back"
registration rights with respect thereto. In addition, the holders of the Series
A Preferred Stock would have special voting rights along with the holders of the
Series B Preferred Stock with respect to certain enumerated transactions, and it
is currently anticipated that all holders of the Series A Preferred Stock will
be required to enter into the Stockholders' Agreement. See "Offering -
Stockholders' Agreement."

                        DETERMINATION OF OFFERING PRICE

     The offering price of $1,500 per Share was determined solely by the Board
based on a number of factors, including the date of the Company's hiring of the
offerees and a comparison of the Company's 1994 and projected 1995 financial
performance to the financial performance and corresponding per share market
multiples of a select group of public companies involved in the natural gas
compressor leasing and fabrication and energy services industries. By virtue of
the nature of this offering, the offering price was not determined pursuant to
arm's length negotiations with a third party, and there can be no assurance that
such price is indicative of the fair market value of the Shares.

                               PLAN OF OFFERING

     The minimum purchase per subscribing offeree is one Share (excluding Shares
to be acquired by delivery of a Four Year Note) for a minimum aggregate purchase
price of $1,500. The minimum aggregate purchase for all Investors is two hundred
Shares (excluding Shares to be purchased by delivery of a Four Year Note) for a
minimum aggregate purchase price of $300,000. The Company reserves the right (i)
to reject any subscription for any reason and (ii) to make non-material
modifications to or terminate this offering at any time for any reason.

     Each offeree who desires to subscribe for Shares must (i) on or before
Tuesday, August 8, 1995, call Curtis Bedrich (at 713-447-8787) to communicate
the number of Cash Shares and Loan Shares for which such offeree desires to
subscribe and (ii) on or prior to Friday, August 11, 1995, execute and return to
the Company, c/o Curtis Bedrich, (a) one copy and one extra signature page of
the Subscription Agreement included herewith (including Schedule A attached

                                      21
<PAGE>

thereto), and (b) one copy and one extra signature page of the Stockholders'
Agreement included herewith (including the spousal consent, if applicable).

     Upon oral confirmation of the number and type of Shares subscribed for by a
subscribing offeree, the Company will prepare and distribute for execution to
such subscribing offeree (i) one execution copy of each of the Loan Agreement
and Four Year Note, if applicable, (ii) two copies of the Pledge Agreement, if
applicable, (iii) two copies of the Employee Option Agreement, (iv) an
assignment separate from certificate, if the subscribing offeree has requested a
Four Year Loan and (v) an IRS Form W-9. In addition to the Subscription
Agreement and the Stockholders' Agreement previously delivered, each subscribing
offeree must then, prior to Friday, August 25, 1995, return to the Company, c/o
Curtis Bedrich, to the extent applicable, (i) the executed Loan Agreement and
Four Year Note, (ii) two executed counterparts of the Pledge Agreement, (iii)
two executed counterparts of the Employee Option Agreement, (iv) the assignment
separate from certificate, executed in blank, (v) the fully completed and
executed Form W-9 and (vi) if applicable, a check in an amount equal to the
product of (a) the number of Cash Shares subscribed for and (b) $1,500.

     The foregoing deadlines are summarized as follows:

     All Funds shall be promptly deposited in an interest bearing, segregated
account and such Funds may be invested in treasury bills or other cash
equivalents, as determined in the sole and absolute discretion of the Company.
If acceptable subscriptions for a minimum of an aggregate of two hundred Shares
are received by the Company on or before August 11, 1995, or such later time as
determined in the sole and absolute discretion of the Company without notice to
or consent of the offerees, but in no event later than the Termination Date, all
Funds will be transferred from the segregated bank account to the Company,
together with all interest, if any, earned thereon. In the event such condition
has not been satisfied on or before the Termination

<PAGE>

Date or this offering is withdrawn by the Company, this offering will be
terminated and all Funds will be returned to the subscribing offerees with a pro
rata share of interest earned thereon, calculated on the basis of the amount of
Funds invested by each subscribing offeree and the length of time interest on
such Funds was earned.

                                USE OF PROCEEDS

     Assuming all of the Shares are issued, the net proceeds of the offering,
estimated to be $2,975,000, will be used for general corporate purposes,
including working capital.

                                   DILUTION

     As of March 31, 1995, the Company had adjusted net tangible book value
(defined as total stockholders' equity less goodwill) of $54,206,805, or $644.45
per share of Common Stock (after giving effect to the 1995 Management Offering).
Adjusted net tangible book value per share of Common Stock is determined by
dividing the actual net tangible book value by the number of shares of its
Common Stock and treating all such Common Stock as having been issued for cash
which would have been outstanding as of March 31, 1995 (after giving effect to
the 1995 Management Offering). After giving effect to the sale of the Shares and
the application by the Company of the estimated net proceeds therefrom as
described in "Use of Proceeds" (and after giving effect to the 1995 Management
Offering), the pro forma net tangible book value of the Company as of March 31,
1995 would have been $57,206,805, or $664.32 per share of Common Stock. This
value represents an immediate increase in the adjusted net tangible book value
of $19.87 per share of Common Stock to the current shareholders and an immediate
dilution in net tangible book value of $835.68 per Share to purchasers of the
Shares. Dilution per share is determined by subtracting the pro forma adjusted
net tangible book value per share of Common Stock after the completion of this
offering from the per share price paid by purchasers of the Shares. The
following table (1) illustrates this per share dilution:

<TABLE>

     Common Stock reserved for issuance pursuant to options which have
     previously been granted to certain members of management. To the extent
     such options are exercised, the value of Shares purchased by Investors may
     be subject to further dilution. See "Capitalization," "The Offering - Stock
     Options" and "Description of Capital Stock - Options."

business and therefore does not anticipate paying any dividends on the Common
Stock in the foreseeable future. In addition, the ability of the Company to pay
dividends is limited by the terms of the Credit Agreement and the Subordinated
Loan Agreement, and may be further limited by the terms of the contemplated
Stand-by Credit Facility, Series B Preferred Stock Issuance and Series A
Preferred Stock Issuance.

</TABLE>

                    MANAGEMENT'S DISCUSSION AND ANALYSIS OF
                FINANCIAL CONDITION AND RESULTS OF OPERATIONS

General

     The Company's primary operations consist of three business segments. The
principal segment consists of the leasing and maintenance of the Company's
natural gas compressor units ("Leasing and Maintenance"), and the other segments
consist of the design, engineering and fabrication of natural gas compressor
units ("Compressor Packaging") and the design, engineering and fabrication of
oil and gas production equipment ("Production Equipment"). See "Business -
Operations."

     The Company commenced operations during the latter part of 1990 with the
acquisition of three regional compression leasing companies. In addition, a
compression leasing and fabricating operation was acquired in July, 1991. A
machine shop operation acquired by the Company in 1990, Precision Welding &
Machine, Inc., a Texas corporation ("PWMI"), was sold by the Company in November
1993. See "Business - Company History." The compression rental fleet has been
expanded significantly since the Company's inception, and amounted to 926 units
aggregating 258,979 horsepower at March 31, 1995. This growth has been funded by
a combination of internally generated cash flow, bank financing and additional
equity in the form of Common Stock sold to the Company's management group and
existing shareholders in 1992 and 1993, as well as the commencement of
Production Equipment activities in 1993. As

                                      26
<PAGE>

discussed elsewhere herein, the operation of the Production Equipment segment
has been significantly enhanced by the Smith Acquisition. See "Business -
Company History."

Liquidity and Capital Resources

     Earnings before depreciation and amortization and income taxes amounted to
$15.1 million during 1994. Other significant sources of funds during 1994 were
amounts available under the Credit Agreement. Significant uses of funds included
the repayment of debt under the Credit Agreement and net capital expenditures
aggregating $31.8 million during 1994.

     The financing necessary to support the Company's historical operations has
principally been provided from borrowings under the Credit Agreement and sales
of Common Stock.

     For a discussion of the Company's anticipated capital expenditures for the
next two years, see "Business - Business Strategy."

     Historically, inflation has not had a significant impact on the operations
of the Company.

Results of Operations

Year ended December 31, 1994 compared to year ended December 31, 1993

Revenues

     Revenues from Leasing and Maintenance increased by $6.3 million, or 25%,
from $25.7 million in 1993 to $32.0 million in 1994. This increase resulted
primarily from the addition of 168 compression units, aggregating 84,060
horsepower, to the compressor rental fleet. Monthly horsepower utilization of
94% to 96% during 1994 was consistently in excess of the industry average.

     Revenues from Compressor Packaging increased by $2.2 million, or 13%, from
$14.0 million in 1993 to $16.2 million in 1994. This increase resulted from an
increase in the volume of Compressor Packaging during 1994 following the move in
August, 1993, to an expanded fabrication facility. Compressor Packaging
operations generated operating profit (earnings before depreciation and
amortization expense and interest expense) of $1,270,000 during 1994, as
compared to $814,000 during 1993.

     Revenues from Production Equipment increased by $4.1 million, or 129%, from
$3.2 million in 1993 to $7.3 million in 1994. This increase resulted from an
increase in the volume of production equipment fabrication as well as 1994 being
the first full year for production equipment packaging, the operations of which
commenced in March, 1993. Production Equipment operations resulted in an
operating profit (earnings before depreciation and amortization expense and
interest expense) of $364,000 during 1994, as compared to an operating loss of
$130,000 during 1993.

                                      27
<PAGE>

Expenses

     Leasing and Maintenance expenses increased by $1.3 million, or 13%, from
$9.7 million in 1993 to $11.0 million in 1994. This increase resulted from
additions to the compressor rental fleet as reflected by a 25 % increase in
Leasing and Maintenance revenue.

     Costs and expenses of Compressor Packaging increased by $1.6 million, or 13
%, from $12. 1 million in 1993 to $13.7 million in 1994. This increase is
attributable to the increase in Compressor Packaging operations.

     Costs and expenses of Production Equipment increased by $3. 1 million, or
117 %, from $2.7 million in 1993 to $5.8 million in 1994. This increase resulted
from an increase in the volume of production equipment fabrication and the
inclusion of a full year of operations in 1994.

     Selling, general and administrative expenses increased by $1.0 million, or
14% from $7.4 million in 1993 to $8.4 million in 1994. This increase resulted
from the expanded level of activity in each of the Company's business segments.

     Depreciation and amortization increased $2.3 million, or 41%, from $5.8
million in 1993 to $8.1 million in 1994. This increase resulted from additions
to the rental fleet and other capital expenditures which aggregated $31.8
million during 1994.

     Interest expense increased $700,000, or 56%, from $1.3 million in 1993 to
$2.0 million in 1994 as a result of borrowings under the Credit Agreement which
was utilized to finance additions to the compressor rental fleet.

     The Company's effective income tax rate approximates the statutory income
tax rate during 1994 and 1993. Accordingly, the $1.0 million increase, or 62%,
from $1.6 million in 1993 to $2.6 million in 1994 results from a comparable 63 %
increase in income before income taxes from 1993 to 1994.

                                   BUSINESS

Company History

     The Company was incorporated in Delaware in October 1990 as a majority-
owned subsidiary of Hanover Energy Inc., a Texas corporation ("HEV). In November
and December 1990, the Company acquired all of the capital stock of Guerra
Engineering, Inc., a Texas corporation ("GEI"), Energy Recovery Systems, Inc., a
Texas corporation ("ERSI"), and PWMI, and substantially all of the assets of C&B
Compression Sales and Service, Inc., a Louisiana corporation ("C&B"), which
acquisitions were accounted for using the purchase method of accounting.

     In May 1991, HEI was acquired by Hanover Energy Holding Corporation, a
Delaware corporation ("HEHC"), the principal stockholders of which were GKH.

                                      28
<PAGE>

     In July 1991, HEHC acquired all of the common stock of Maintech
Enterprises, Inc., a Texas corporation ("MEV), through a subsidiary created
solely for that purpose. Such subsidiary was subsequently merged into MEI, and
HEHC contributed the stock of MEI to the Company in April 1992 in connection
with the refinancing of the Company's then current senior credit facility. As a
result of the acquisition of MEL the Company acquired a 50 % interest in a joint
venture, the operations of which consisted of leasing natural gas compressor
units. The remaining interest in the joint venture was acquired by the Company
effective April 1. 1993 and the joint venture was liquidated shortly thereafter.

     Effective December 31, 1992, HEI merged into HEHC, and as a result thereof,
the Company became a direct majority-owned subsidiary of HEHC. Also effective as
of December 31, 1992, GEI and ERSI merged into the Company and, as a result
thereof, the separate existence of GEI and ERSI ceased and all of their
respective assets and liabilities became vested in the Company.

     On June 24, 1993, Hanover Pipeline Company, a Delaware corporation and a
wholly-owned subsidiary of HEHC ("HPC"), was merged with and into the Company
(the "HPC Merger"). Pursuant to the HPC Merger, the Company issued to HEHC 2,38
1. 11 shares of Common Stock. HPC's assets consisted of 16 natural gas
compressors. HPC had certain potential environmental liabilities estimated at
December 31, 1992 to be between $139,000 and $200,000; however, pursuant to the
merger agreement, HEHC agreed to indemnify the Company for any diminution in
value to the HPC common stock caused by the incurrence by HPC of any
environmental liability.

     On October 7, 1993, the Company acquired all of the issued and outstanding
stock of Hanna Compressor Group, Inc., an Arkansas corporation ("Hanna
Compressor"), from Hanna Investment Group, an Arkansas general partnership
("HIG"), in exchange for 1,875 shares of Common Stock (the "Hanna Acquisition").
Hanna Compressor's assets consisted of (i) six natural gas compressor units,
(ii) a 4,000 foot combination division office and maintenance facility situated
on five acres of land in Pocola, Oklahoma and (iii) cash. In connection with the
Hanna Acquisition, the Company, HEHC, GKH and HIG entered into the Hanna
Stockholders' Agreement. See "Principal Stockholders - Stockholders' Agreements
- Hanna Stockholders' Agreement."  Effective as of February 9, 1994, Hanna
Compressor was merged into the Company and, as a result thereof, the separate
existence of Hanna Compressor ceased and all of its assets and liabilities
became vested in the Company.

     On November 5, 1993, the Company sold all of the issued and outstanding
capital stock of PWMI to a corporation (the "PWMI Purchaser") controlled by two
former employees of PWMI (the "PWMI Employees") for a purchase price equal to
$500,000. The purchase price was. paid in the form of two secured promissory
notes, one in the principal amount of $475,000 and the other in the principal
amount of $25,000, each of which bear interest at 8% per annum. The $475,000
note has a ten year amortization, and is payable to the Company in equal monthly
installments of principal and interest beginning on December 1, 1993, with the
entire outstanding balance due and payable December 1, 1996. The PWMI Purchaser
has missed a number of payments under the promissory notes, and the Company and
the PWMI Purchaser are currently

                                      29
<PAGE>

in the process of negotiating a new payment schedule under the notes. The
obligations of the PWMI Purchaser under the notes are guaranteed jointly and
severally by the PWMI Employees, which guarantee is secured by a pledge to the
Company of the PWMI capital stock, as well as a security interest in certain
assets of PWML.

     On January 27, 1995, HEHC was merged with and into the Company (the "HEHC
Merger") and, as a result thereof, the separate existence of HEHC ceased and all
of its assets and liabilities became vested in the Company. Pursuant to the HEHC
Merger, the Company issued to the stockholders of HEHC in the aggregate 59,053.
11 shares of Common Stock, which was equal to the number of shares of Common
Stock owned by HEHC immediately prior to the HEHC Merger. In connection
therewith, the Company, GKH and the other stockholders of HEHC immediately prior
to the Merger entered into the HEHC Stockholders' Agreement. See "Principal
Stockholders - Stockholders' Agreements - HEHC Stockholders' Agreement" for a
discussion of the terms of the HEHC Stockholders' Agreement. In addition, each
former stockholder of HEHC agreed to indemnify the Company for (i) the breach or
inaccuracy of any representation or warranty made by HEHC or such stockholder
under the HEHC Merger Agreement and (ii) the breach or default of any agreement
by HEHC or such stockholder under the HEHC Merger Agreement, payable in shares
of Common Stock issued in the HEHC Merger.

     Effective as of January 1, 1995, the Company acquired from CBC Compression,
an Oklahoma general partnership ("CBC"), 40 natural gas compressor units and
certain related equipment for a purchase price of $3,025,000 plus five percent
of rental amounts (exclusive of sales tax, freight and installation charges)
received by the Company under the related Master Gas Compression Agreement
described below. Pursuant to an agreement (the "Master Gas Compression
Agreement") with AnSon Company, a sister partnership of CBC ("AnSon"), the
Company agreed to lease the 40 compressors back to AnSon, along with at least 25
additional compressors, for an initial term of 24 months. The Master Gas
Compression Agreement is scheduled to continue for an additional 24-month period
beyond the initial 24-month period; however, the rental price during such period
has not been established. AnSon, CBC and the Company have also entered into a
48-month "most favored vendor" relationship whereby AnSon and CBC have agreed to
purchase or lease production equipment from the Company so long as the Company's
price is equal to or less than other bidders. Similarly, the Company has agreed
to retain trucking services from MB Oilfield Service (an affiliate of CBC and
AnSon) during such 48-month period so long as MB Oilfield Service's price is not
higher than other bidders for such services.

     Effective as of February 1, 1995, the Company purchased from Gale Force
Compression Services, Inc. ("Gale Force") 107 natural gas compressors, certain
furniture, fixtures, equipment and other fixed assets, vehicles, the name "Gale
Force". and equipment leases for an aggregate purchase price of $9,782,800 plus
1, 150 shares of Common Stock (the "Gale Force Acquisition"). The compressors
are located primarily in Oklahoma and most are currently leased by the Company
pursuant to leases transferred in the sale. Concurrently with the Gale Force
Acquisition, the Company entered into a four year alliance agreement with Ward
Petroleum, an affiliate of Gale Force, for gas compression services to be
provided by the Company. In connection with the Gale Force Acquisition, the
Company, GKH and those persons who acquired

                                      30

Common Stock pursuant to the transaction entered into the Gale Force
Stockholders' Agreement. See "Principal Stockholders - Stockholders'
Agreements - Gale Force Stockholders' Agreement" for a discussion of the terms
of the Gale Force Stockholders' Agreement. Also in connection with this
transaction, the Company entered into an employment agreement with Alan D.
Lavenue, a Gale Force affiliate, for a two year term.

     On February 24, 1995, the Company, through its wholly-owned subsidiary,
Hanover/Smith, Inc. ("Hanover/Smith"), acquired (the "Smith Acquisition")
substantially all of the operating assets of the oil and gas production
equipment division of Smith Industries, Incorporated, a Delaware corporation
("Smith"), which has been in the fabrication of oil and gas production equipment
industry since its inception in 1927. The assets acquired include real property
located in Corpus Christi, Texas, a lease and purchase option on real property
located in Columbus, Texas, manufacturing equipment used in the fabrication of
oil and gas production equipment, vehicles, inventory, the name "Smith
Industries" and Smith's logo. Smith filed for protection under the United States
Bankruptcy Code, 11 U. S. C. (S) 101 et seq., in May 1994, in the United States
                                     -- ----
Bankruptcy Court for the Southern District of Texas, Houston Division, in a Case
styled In Re: Smith Industries, Incorporated, No. 94-43705-H3-11.  The
Bankruptcy Court approved the necessary orders authorizing the acquisition. The
total acquisition price after various credits and adjustments was $2,595,714.
The oil and gas production equipment operations of Smith acquired by
Hanover/Smith have been consolidated with the existing oil and gas production
equipment fabricating operations of the Company and will operate as
Hanover/Smith.

Industry

     Natural gas compressors generally do not suffer significant technological
obsolescence, so that the useful life of a compressor is based primarily on its
mechanical integrity. The useful life of a compressor may also be extended by
refurbishing or overhauling the compressor at regular intervals of approximately
five to six years. Refurbished or overhauled compressors may be leased at prices
substantially similar to new compressors.

     The gas compressor industry services both independent producers and major
integrated natural gas producers, as well as pipeline, gas processing and
gathering and transmission companies, and is substantially dependent on the
natural gas industry. The Company believes that independent producers currently
account for a substantial portion of the natural gas industry. The Company also
believes that independent gas producers are now accounting for an increasing
portion of the natural gas produced in the United States relative to that
produced by major integrated energy producers and that independent producers are
more likely to lease compressors from third parties such as the Company as a
result of restraints on their ability to make the large capital expenditures
necessary to purchase compressors. In addition, many major gas producers are
directing their capital investments overseas and allowing their U.S. capital
base to decline, thus resulting in further increased demand for rental
compressors. Moreover, the market for contract compression services has been
expanding as gas producers and pipeline companies strive to lower operating
costs and improve efficiency by outsourcing their gas handling requirements.

                                      31
<PAGE>

     The Company believes that the market for natural gas compressors is driven
by a variety of factors, including, without limitation, (i) the demand for
natural gas, (ii) the age of particular gas wells, (iii) the relative price of
natural gas to the price of oil or other alternative energy sources and (iv) the
season.  All other things being equal, the gas compression industry is generally
benefited by either an increase in gas prices, which generally results in the
development of new wells, fields and pipeline systems and a corresponding
increase in demand for compression, or, up to a point, by a decrease in natural
gas prices, which results in outsourcing by independent producers and an
increase in the need for leased compression. Increases in the age of natural gas
wells also has a positive impact on the gas compression industry since older
wells generally experience a decline in their reservoir pressure and require
compressors to increase their productivity. In contrast, a number of factors
would potentially have an adverse effect on the gas compressor industry. See
"Risk Factors - Natural Gas Compressor Industry Considerations."

     Conversely, all other things being equal, a relative decrease in the price
of oil or other energy sources as compared to natural gas generally will have an
adverse effect on the natural gas compression industry since such circumstances
encourage energy users to switch from natural gas to alternative fuel sources
thereby decreasing demand for natural gas.

     The Company believes that the natural gas compressor industry is also
affected by seasonality, with the highest demand for compression in winter
months when natural gas is in greater demand. As a result of such seasonality,
the Company generally experiences slightly decreased revenues for its Leasing
and Maintenance segment during the months of May through August.

     In addition, the Company believes that as environmental considerations
become more important due to the Federal Clean Air Act and related legislative
and social considerations, natural gas, as a cleaner burning fuel than either
oil or coal, will make up a greater share of the domestic energy market.
However, there can be no assurance that such increased use of natural gas will
come to pass.

Market Position

Leasing and Maintenance

     The Company believes that the market for the leasing of natural gas
compressors may be distinguished from the market for the sale of natural gas
compressors since the decision to lease a compressor is generally made prior to
a customer's entrance into the marketplace. Generally, lessees are customers who
anticipate only a short term need for the compressor which is substantially less
than the estimated useful life of the unit or customers who are unable to or
otherwise choose not to internally finance the purchase of such units.

     The Company believes that the natural gas compressor leasing industry may
be divided into categories based on the compressor horsepower and that market
share of the participants in the industry may be determined based on either (i)
the number of units leased by such participants or (ii) the total horsepower
leased by such participants.

</TABLE>

     Based on industry statistics, the Company believes that the U.S. natural
gas compressor leasing industry is a highly fragmented business made up of in
excess of 50 companies aggregating approximately 2,200,000 horsepower. Based on
information available to the Company, the Company believes that it is the fourth
largest compressor leasing company in the U.S. based on total units and the
third largest compressor leasing company in the U.S. based on total operating
horsepower.

Compressor Packaging

     The Compressor Packaging business, carried on primarily through MEI,
competes with other manufacturers of compressor units. The Compressor Packaging
business is dominated by a few major competitors, several of whom also compete
with the Company in the compressor leasing business. Although sufficient
information is not available to definitively estimate the Company's relative
position in the Compressor Packaging market, management believes that the
Company is the seventh largest Compressor Packaging company in the U.S. based on
estimated 1994 revenues of the Company's competitors in such business.

Production Equipment

     The Production Equipment business is a highly fragmented business with
approximately five substantial competitors. The Company believes that, with the
Smith Acquisition, it is among the top five major competitors in the business.

Business Strategy

     The Company's primary focus will be continued expansion of the compression
rental fleet. Anticipated levels of capital expenditures, from internally
generated cash flow and bank financing, relating to the rental fleet amount to
approximately $27 million during 1995 and $17 million during 1996. If the
Company is successful in raising the additional growth capital which it
anticipates during 1995, management estimates that capital expenditures related
to the rental

                                      33
<PAGE>

fleet will amount to approximately $37 million and $36 million during 1995 and
1996, respectively. The rental fleet consisted of 926 units aggregating 258,979
horsepower at March 31, 1995. With the level of capital expenditures
contemplated, assuming the additional growth capital is raised, management
believes that the Company's rental fleet should grow to approximately 300,000
horsepower by year end 1995. In addition, the contribution of the Production
Equipment segment is expected to increase, both in terms of revenues and
operating income, in light of the Smith Acquisition. However, there can be no
assurances that the above projections will actually be met.

     The Company does not anticipate making any significant expenditures for
product research and development inasmuch as the Company's Leasing and
Maintenance, Compressor Packaging and Production Equipment segments do not
generally require such expenditures.

Leasing and Maintenance

     The Company provides natural gas compression equipment, on a rental basis,
primarily to natural gas production and transmission companies. These rental
units are utilized to compress natural gas when the reservoir pressure for a
natural gas field is less than the pressure for the natural gas pipeline
transporting the gas. The Company also provides maintenance of customer-owned
compressor units as well as compressor parts sales to third parties.

     As of March 31, 1995, the Company's gas compressor fleet consisted of 926
units, ranging from 25 to 3,000 horsepower, of which 94% of available horsepower
and 92% of the available units were being utilized.  Leases for the compressor
units provide for fixed monthly payments for an average term of approximately
six months and continue thereafter on a monthly basis. Based on the Company's
historical operations, the Company estimates that the terms of its leases have
extended for an average of approximately 24 months.

     Although natural gas compressors generally do not suffer significant
technological obsolescence, they do require routine maintenance and periodic
refurbishing to prolong their useful life. In general, the Company anticipates
refurbishing its compressor units approximately every five to six years.

     The Company's compressor leasing activities are located in Texas, Oklahoma,
Arkansas, Louisiana, New Mexico, Mississippi, Alabama, Kansas and offshore Gulf
of Mexico, and the Company is considering expansion into international markets.
In this regard, the Company presently leases a gas compressor to a company in
Trinidad pursuant to a 24-month lease which provides for payments of $7,800 per
month and two 12-month extension periods. In addition, the Company currently
owns four compressors under lease with Corpoven, S.A., the Venezuelan natural
gas company.

Compressor Packaging

     The Company's Compressor Packaging segment, operated primarily through MEI,
designs, engineers and assembles compression units for sale to third parties as
well as for placement in its compressor fleet. In general, units to be sold to
third parties are assembled according to such customer's specifications and sold
on a turnkey basis. Components for such

                                      35
<PAGE>

compressor units are acquired from third party suppliers. At March 31, 1995,
backlog of fabrication of compressor units amounted to $6.1 million.

Production Equipment

     The Company designs and fabricates a broad range of oil and gas production
equipment designed to heat, separate, dehydrate and measure crude oil and
natural gas. The product line includes line heaters, oil and gas separators,
glycol dehydration units and skid mounted production packages designed for both
onshore and offshore production facilities. At March 31, 1995, backlog of
production equipment fabrication amounted to $3.6 million.

Customers

     No amounts received from any individual customer equaled more than 10% of
the Company's consolidated revenues during 1993 or 1994.

Competition

Leasing and Maintenance

     The natural gas compressor leasing business is highly competitive. Overall,
the Company experiences considerable competition from larger companies with
significantly greater financial resources and, on a regional basis, several
smaller companies compete directly with the Company. Based on information
available to the Company, the Company ranks among the top four companies
providing compressor units on a rental basis based on the number of units and
among the top three based on total available horsepower. See "- Market
Position."

     The Company believes that it competes in the Leasing and Maintenance
segment on the basis of price, customer service, including the availability of
personnel in remote locations, flexibility in meeting customer needs and quality
and reliability of its compressors. Although the Company believes that it is
competitive in terms of price and quality, it also focuses on customer service
and flexibility in meeting customer needs.

Compressor Packaging

     The Company believes that it competes in the Compressor Packaging segment
based on price and quality and that the Company is competitive in both areas.

Production Equipment

     The Company believes that it competes in the Compressor Packaging segment
based on price and quality and that the Company is competitive in both areas.
Competition in the Production Equipment segment is also based on the ability to
service customers' needs. The Company believes that with the Smith Acquisition,
it is among the top five major competitors in the Production Equipment market.

Employees

                                      36
<PAGE>

     As of March 31, 1995, the Company employed approximately 398 people, of
which 15 were administrative, 18 were sales, 84 were Compressor Packaging, 110
were Production Equipment and 171 in field service locations. No employees are
represented by labor unions, and the Company believes that its relations with
its employees is satisfactory.

Insurance

     Natural gas operations are subject to certain risks, including explosions,
uncontrollable flows of gas or well fluids, fires, pollution and other
environmental risks. These risks could expose the Company to substantial
liability for injury and loss of life, property damage, pollution and other
environmental damages, and consequential damages, if such damages resulted from
a compressor defect or from the Company's negligence in maintaining, servicing
or refurbishing its compressors.

     The Company believes that is has obtained adequate insurance to cover such
risks; however, no' assurance can be given that such insurance will be adequate
to cover the Company's operations in the event the Company incurs liability in
excess of anticipated potential levels or that such insurance will be generally
available in the future or, if available, that premiums will be commercially
reasonable. See "Risk Factors - Potential Liability and Insurance."

Properties and Assets

     As of March 31, 1995, the Company's rental fleet consisted of 926
compressor units, 6 of which are leased and the remainder of which are owned by
the Company, with a total of 258,979 horsepower and an average of 280
horsepower. The Company also owns those assets acquired in the Gale Force

     The Company owns its corporate offices in Houston, Texas, which are housed
in a combination corporate office and compressor fabrication facility consisting
of approximately 190,000 square feet plant capacity located on twenty acres.
This facility is anticipated to provide the Company with sufficient space and
capacity for at least the next three years. The Company also owns (i) a 6,400
square foot combination office and maintenance shop located on two acres in
Oklahoma City, Oklahoma, (ii) a 4,000 foot combination division office and
maintenance facility situated on five acres of land in Pocola, Oklahoma, (iii)
its maintenance facilities in Midland, Texas and Fort Smith, Arkansas, (iv) real
property located in Corpus Christi, Texas and (v) a lease and purchase option
regarding the 212,000 square feet manufacturing facility located on 83 acres in

Litigation

     The Company is not a party to any litigation that, in the judgment of
management, would have a material adverse effect on the Company's operations or
financial condition if adversely determined.

Governmental Regulation

     The Company is subject to various federal and state laws and regulations
relating to environmental protection, including regulations regarding emission
controls - The Company believes that it is in substantial compliance with such
laws and regulations and that the phasing in of emission controls and other
known standards at the rate currently contemplated by such laws and regulations
will not have a material adverse effect on the Company's financial condition or
results of operations. However, various state and federal agencies from time to
time consider adopting new laws and regulations or amending existing laws and
regulations regarding environmental protection. While the Company may be able to
pass on the additional costs of complying with such laws, there can be no
assurance that attempts to do so would be successful. Accordingly, new laws or
regulations or amendments to existing laws or regulations could require the
Company to undertake significant capital expenditures and could otherwise have a
material adverse effect on the Company's financial condition and results of
operations.

     From time to time since President Clinton took office, his administration
has proposed various taxes with respect to the energy industry, none of which
have been enacted and all of which have received significant scrutiny from
various industry lobbyists. At the present time, given the uncertainties
regarding the proposed taxes, including the uncertainties regarding the terms
which the proposed taxes might ultimately contain and the industries and persons
who may ultimately be subject to any such tax, it is not possible to determine
whether any such tax will have a material adverse effect on the Company.

Options

1992 Stock Plan

     In April 1992, the Board adopted the Company's Stock Compensation Plan (the
"1992 Stock Plan"), which provides for the granting of options to executive
officers, directors, employees or advisors of the Company. The 1992 Stock Plan
permits the Board to issue options with respect to a maximum of 15 % of the
total shares of Common Stock outstanding, computed on a fully diluted basis and
including shares which are issuable under the 1992 Stock Plan, at the time of
the grant of an option. As of March 31, 1995, options with respect to 1,065
shares of Common Stock were outstanding, 670.5 of which were presently vested,
and the remainder of which will generally vest ratably over the next two years.
214.5 of such options are exercisable at $1.00 per share and 850.5 are
exercisable at $725 per share. Options granted under the 1992 Stock Plan are
nonstatutory options and are not classified as "incentive stock options" within
the meaning of Section 422 of the Code.

     The exercise price for additional options which may be granted under the
1992 Stock Plan would be determined by a committee appointed by the Board (the
"Committee"), which Committee is currently comprised of the members of the
Board, and may be less than the fair market value of the Common Stock on the
date of grant. Other than the maximum number of shares available under the 1992
Stock Plan, there is no minimum or maximum number of shares that may be granted
to any person. Options granted under the 1992 Stock Plan generally expire within
a specified number of days of the termination of

                                      41
<PAGE>

employment of an optionee who is an employee. Options granted under the 1992
Stock Plan fully vest and become exercisable for a specified number of days upon
the death or permanent disability of the optionee and are forfeited upon the
termination for cause of the optionee. In addition, options granted under the
1992 Stock Plan fully vest and become exercisable upon the occurrence of a
change in control accompanied by a constructive termination of employment of
such optionee, all as more fully described in the 1992 Stock Plan.

     Options may not be transferred other than by will or the laws of descent
and distribution, and during the lifetime of an optionee may be exercised only
the optionee. The term of each option granted under the 1992 Stock Plan may not
exceed fifteen years from the date the option is granted. Options may become
exercisable in whole at grant or in installments over time, as determined by the
Committee. Under the terms of the 1992 Stock Plan, payment upon the exercise of
an option may be in cash, by delivery of shares of Common Stock with a fair
market value equal to the aggregate exercise price or, if the optionee's stock
option agreement so provides, by delivery of a promissory note with such terms
as the Committee may approve.

     The acceleration of options in the event of a change of control could be
seen as an anti-takeover provision and may have the effect of discouraging a
proposal for merger or other efforts to purchase or sell control of the Company.

1993 Option Plan

     In connection with the 1993 Offering, the Board adopted the 1993 Management
Stock Option Plan (the " 1993 Option Plan") pursuant to which members of the
Company's management who purchased Common Stock in the 1993 Offering were issued
options to purchase one-third of one share of Common Stock at a purchase price
of $725 per share (subject to adjustment for stock splits, stock dividends and
other similar events) for each share of Common Stock owned by such persons or
purchased by such persons in the 1993 Offering. Such options vest ratably over a
five year period which began on June 23, 1993 and are governed by the terms of
the 1993 Option Plan and individual option agreements (the " 1993 Option
Agreements"). As of March 31, 1995, options with respect to 1,514 shares of
Common Stock were outstanding, and options with respect to 302.80 were presently
vested. Other than with respect to the applicable exercise price and the actual
vesting and expiration dates, the 1993 Option Plan and the 1993 Option
Agreements are substantially the same as the Employee Option Plan and the
Employee Option Agreements, respectively.

Senior Executive Plan

     In connection with the 1993 Offering, Messrs. O'Connor and McGhan were
granted options pursuant to the Company's Senior Executive Stock Option Plan
(the "Senior Executive Plan") to purchase up to 1,291.95 and 645.97 shares of
Common Stock, respectively, at an exercise price of $833.75 per share (subject
to adjustment for stock splits, stock dividends and similar events). Such
options vest ratably over a seven year period which began on June 29, 1993 and
will fully vest upon an optionee's death or permanent disability or upon the
occurrence of a Capital Event (as defined in the Senior Executive Plan)
resulting in a compounded annual return of 20% actually realized on the shares
of Common Stock purchased in the 1993 Offering. In

                                      42
<PAGE>

addition, on May 15, 1995, Messrs. McGhan and Bedrich were granted 215.32 and
430.65 options, respectively, under the Senior Executive Plan. Such options have
the same terms as those issued to Messrs. O'Connor and McGhan in connection with
the 1993 Offering, except that such options will vest ratably over a seven year
period which began on May 15, 1995.

     Options granted under the Senior Executive Plan generally expire within a
specified number of days of the termination of employment of an optionee, and
such options will be forfeited upon the termination for Cause of an optionee.
The term of each option may not exceed 10 years from the date the option is
granted. Options may not be transferred other than by will or the laws of
descent and distribution, and during the lifetime of an optionee may be
exercised only by the optionee. Options granted under the Senior Executive Plan
are nonstatutory options and are not classified as "incentive stock options"
within the meaning of Section 422 of the Code.

     Pursuant to the agreements executed in connection with the grant of options
under the Senior Executive Plan, each of Messrs. O'Connor, McGhan and Bedrich
agreed that he will not during the term of such agreement and for a period of
one year thereafter, (i) compete with any business of the Company and (ii)
without the Company's consent, disclose to persons outside the Company
confidential information concerning the Company.

1995 Management Option Plan

     In connection with the 1995 Management Offering, the Board adopted the 1995
Management Stock Option Plan (the " 1995 Management Option Plan"), pursuant to
which members of the Company's management who purchased Common Stock in the 1995
Management Offering were issued options to purchase one-third of one share of
Common Stock at a purchase price of $1,100 per share (subject to adjustment for
stock splits, stock dividends and other similar events) for each share of Common
Stock purchased by such persons in the 1995 Management Offering. Such options
vest ratably over a five year period which began on July 7, 1995, and are
governed by the terms of the 1995 Management Option Plan and individual option
agreements (the "1995 Management Option Agreements"). As of the date of this
Offering Memorandum, options with respect to 83.33 shares of Common Stock were
outstanding, none of which were presently vested. Other than with respect to the
applicable exercise price and the actual vesting and expiration dates, the 1995
Management Option Plan and the 1995 Management Option Agreements are
substantially the same as the Employee Option Plan and the Employee Option
Agreements, respectively.

Incentive Option Plan

     In connection with the 1993 Offering, the Board adopted the Company's
Incentive Option Plan (the "Incentive Option Plan"), participation in which is
open to members of management who participated in the 1993 Offering and who are
employed by the Company or any of its subsidiaries or affiliates at the time of
a Capital Event (as defined below) (each a "1993 Eligible Participant"). Given
that the options which may be issued under the Incentive Option Plan are based
on the actual return realized by the controlling stockholder, the Company plans
to replace the Incentive Option Plan with a another option plan which would
include the 1993 Eligible Participants. However, the Investors will not be
eligible to participate in the Incentive

                                      43
<PAGE>

Option Plan, except to the extent of their pro rata participation, if any, in
the 1993 Offering. Nonetheless, a brief description of the Incentive Option Plan
follows.

     Pursuant to the Incentive Option Plan as presently constituted, the Company
may grant 1993 Eligible Participants who are employees of the Company or any of
its subsidiaries or affiliates and who own shares of Common Stock at the time of
a Capital Event (as defined in the Incentive Option Plan) options to acquire a
specified percentage of the shares of outstanding Common Stock (determined on a
fully diluted basis) based on the actual return realized by the controlling
stockholder upon (i) the disposition (other than to affiliates) by GKH of at
least 50% of its Common Stock, (ii) the date all or substantially all of the
assets or property of the Company are sold, leased or otherwise transferred to
an unrelated third party, (iii) the effective date of a merger or consolidation
in which the Company, any of its subsidiaries or any affiliate of the Company is
not the surviving entity or the surviving entity is not controlled by GKH or
(iv) the dissolution or liquidation of the Company (the first occurrence of the
events set forth in items (i) through (iv) is referred to herein as the "Capital
Event").

     The options granted under the Incentive Option Plan would be nonstatutory
options and the exercise price for such options would be $725 per share. The
options would vest fully upon the occurrence of the Capital Event. Each
participant in the Incentive Option Plan will receive a Mr rata share of the
total options actually issued pursuant to the Incentive Option Plan (the
"Incentive Option Plan Shares") determined by multiplying the Incentive Option
Plan Shares by a fraction, the numerator of which is equal to the lesser of (i)
the number of shares of Common Stock subscribed for by such 1993 Eligible
Participant pursuant to the 1993 Offering or (ii) the number of shares of Common
Stock owned by the 1993 Eligible Participant at the time of &.e Capital Event
and the denominator of which is equal to the total number of shares of Common
Stock subscribed for by all 1993 Eligible Participants pursuant to the 1993
Offering. 1993 Eligible Participants who cease to be employed by the Company for
any reason prior to a Capital Event or who cease to own shares of Common Stock
would not be eligible to participate in the Incentive Option Plan.

     Options granted under the Incentive Option Plan generally would expire
within a specified number of days of the termination of employment of an
optionee.  Options may not be transferred other than by will or the laws of
descent and distribution, and during the lifetime of an optionee may be
exercised only by the optionee. The term of each option granted under the
Incentive Option Plan may not exceed 10 years from the date the option is,
granted.

superseded as among the parties thereto by the Stockholders' Agreement. However,
there can be no assurance that each party to such stockholders' agreements will

Registration Rights Agreements

     Of the registration rights agreements described below, only the Amended and
Restated Registration Rights Agreement is currently in effect. The Company
currently anticipates that the Amended and Restated Registration Rights
Agreement (as defined below) will be superseded by the Second Amended and
Restated Registration Rights Agreement. However, there can be no assurance that
each party to the Amended and Restated Registration Rights Agreement will become
a party to the Second Amended and Restated Registration Rights Agreement, and
any such party not becoming a party to the Second Amended and Restated
Registration Rights Agreement would remain a party to and be bound by the
Amended and Restated Registration Rights Agreement.

Amended and Restated Registration Rights Agreement

     The Company, GKH and the other parties to the HEHC Stockholders' Agreement
and the Gale Force Stockholders' Agreement (GKH and such stockholders,
hereinafter "Holders") are party to that certain Amended and Restated
Registration Rights Agreement, dated as of March 8, 1995 (the "Amended and
Restated Registration Rights Agreement"). The Amended and Restated Registration
Rights Agreement generally provides that in the event the Company proposes to
register under the Securities Act shares of its capital stock or any other
securities, then upon the request of those Holders owning in the aggregate at
least 5 % of the Common Stock or derivatives thereof (the "Registrable
Securities") then held by all of the Holders, the Company must use its
reasonable best efforts to cause the Registrable Securities so requested by the
Holders to be included in the applicable registration statement. The Company is
generally not obligated to include a particular Holder's Registrable Securities
in more than one registration, and the Holders' right to have their Registrable
Securities so included is limited in the event and to the extent that the
managing underwriter(s) of the registration in question are of the opinion that
the inclusion of the number of Registrable Securities held by Holders requesting
inclusion in the applicable registration statement would materially interfere
with the underwriters' ability to effectuate the registration and sale of
securities proposed to be offered and sold pursuant to such registration
statement. The Company agrees to pay all registration expenses in connection
with registrations of Registrable Securities effected pursuant to the Amended
and Restated Registration Rights Agreement; however, all fees and expenses
relating to the distribution of such Registrable Securities are borne by the
Company and each Holder pro rata based on the number of Registrable Securities
                        --- ----
included in the registration for the account of the Company and each Holder.

Second Amended and Restated Registration Rights Agreement

     The terms of the Second Amended and Restated Registration Rights Agreement
are substantially similar to those of the Amended and Restated Registration
Rights Agreement, with certain exceptions, including the following: (i) in the
event that the Company proposes to register any of its capital stock or other
securities under the Securities Act, Holders (GKH and the other stockholder
parties thereto) owning at least 2.5% of the outstanding Registrable Securities
are able to trigger the Company's obligation to cause the Registrable Securities
so requested to be

                                      51
<PAGE>

included in the applicable registration statement, (ii) there is no restriction
on the Company's obligation to include Registrable Securities in more than one
registration and (iii) the Company, in connection with filing a registration
statement in accordance with the Agreement, would also have the obligation to
apply for listing and use its reasonable best efforts to list the Registrable
Securities being registered on any national exchange on which a class of the
Company's equity securities is listed, or if there is no class of Company equity
security so listed, then to use its reasonable best efforts to qualify such
Registrable Securities for inclusion on the NASDAQ.

                      DESCRIPTION OF CERTAIN INDEBTEDNESS

     The following summaries relate to (i) certain provisions of the Credit

summary of the provisions relating to the Credit Agreement and the Subordinated
Loan Agreement do not purport to be complete and are qualified in their entirety
by reference to the relevant agreements (including all amendments) relating
thereto, copies of which are available for review at the principal offices of
the Company.

The Credit Agreement

     Pursuant to the Credit Agreement the Company has borrowed $15,000,000 under

Original Term Loan bears interest at a rate equal to LIBOR plus 1.25%, and the B
Tranche Loan bears interest at a rate equal to LIBOR plus 2.0%, and such Loans
mature (absent acceleration) on December 31, 1998 and March 31, 2001,
respectively. In addition to the Term Loans, the Credit Agreement provides for a
five year reducing commitment revolving credit facility (the "Revolver") which
provides for an initial maximum commitment of $35,000,000. Amounts outstanding
under the Revolver bear interest at a rate equal to LIBOR plus 1.0% and the
Revolver matures (absent acceleration) on December 31, 1999. As of March 31,
1995, $35,000,000 was outstanding under the Revolver.

     The Credit Agreement contains certain restrictive covenants that impose
limitations (subject to certain exceptions) on the Company, including, among
others, limitations with respect to (i) maintaining certain ratios, including
ratios with respect to (a) consolidated indebtedness to consolidated
capitalization, (b) consolidated earnings before income tax, depreciation and
amortization to consolidated interest expense and (c) current assets to current
liabilities, (ii) incurring additional indebtedness, (iii) creating, incurring
assuming or suffering to exist any mortgage, pledge, lien or other encumbrance
or security interest, (iv) creating, incurring, assuming or suffering to exist
any guarantee or similar obligation, (v) effecting certain fundamental changes,
including any merger or sale of all or substantially all of the Company's
assets, (vi) selling any of the Company's assets except in the ordinary course
of business or as otherwise permitted, (vii) increasing lease expense in excess
of certain limits, (viii) declaring or paying dividends, (ix) making capital
expenditures in excess of certain prescribed limits, (x) making any advance,
loan or similar investment in any person, (xi) making optional payments or
prepayments or amending the terms of any indebtedness, (xii) entering into any
transaction with

                                      52
<PAGE>

affiliates, (xiii) the sale and leaseback of any of the Company's real or
personal property, (xiv) change the Company's fiscal year and (xv) entering into
any agreement which prohibits the Company from creating liens or other
restrictions on its assets.

     The Credit Agreement contains certain default provisions, including, among
others, (i) failure of the Company to pay any principal or interest thereunder
when due, (ii) breach by the Company or any of its subsidiaries or affiliates
which are parties to the Credit Agreement of any representation or warranty made
therein or in the other documents contemplated thereby, (iii) default by the
Company or any of its subsidiaries in the observance or performance of any
covenant or agreement contained therein or in the other documents contemplated
thereby, (iv) cessation of the security agreement and related documents executed
thereunder to be in full force and effect, (v) default by the Company or any of
its subsidiaries in the payment of any indebtedness or guarantee in excess of
$1,000,000, which default remains in effect for 30 days, or any other breach
under agreements with respect to such indebtedness or guarantees which causes
such indebtedness or guarantee to be accelerated, (vi) occurrence of certain
bankruptcy related events, (vii) occurrence of certain events related to ERISA
obligations, (viii) entering of one or more judgements or decrees against the
Company or any of its subsidiaries involving an aggregate liability of
$1,000,000 or more, (ix) the incurrence by the Company or any of its
subsidiaries of liability for remediation or environmental compliance (or
penalty with respect thereto) in excess of $1,000,000 and (x) the cessation of
GKH to own directly or indirectly 45 % of the issued and outstanding Common
Stock of the Company.

     It is currently anticipated that the Company will use all or a portion of
the proceeds of the sale of shares of Series B Preferred Stock to the Enron
Entity and the sales of the shares of the Series A Preferred Stock to pay down
all or a portion of the term loans currently outstanding under the Credit
Agreement. In addition, it is anticipated that the Company will refinance its
obligations under the Revolver and enter into an expanded revolving facility.
However, there can be no assurance that such transactions will be consummated.

The Subordinated Loan Agreement

     Pursuant to the terms of the Subordinated Loan Agreement, the Company has
borrowed $12,000,000 on an unsecured basis. all of which was drawn down as of
June 6, 1995. The Subordinated Loan bears interest at the Prime Rate plus 5 %,
matures (absent acceleration) on March 3 1. 2002 and is subject to mandatory
prepayment under certain specified circumstances.

     The Subordinated Loan Agreement incorporates the restrictive covenants of
the Credit Agreement by reference and contains default provisions similar to
those in the Credit Agreement.

     The Subordinated Loan Agreement, by its terms, provides that any payments
due to the subordinated lenders thereunder are subordinate and junior to the
rights of the lender under the Credit Agreement.

     It is currently anticipated that all of the holders of the Subordinated
Loan will convert their debt securities into shares of Series A Preferred Stock.
There can, however, be no assurance that such conversion will take place.

                         DESCRIPTION OF CAPITAL STOCK

     The authorized capital stock of the Company currently consists of 200,000
shares of Common Stock and 100,000 shares of Preferred Stock, $.01 par value per
share ("Preferred Stock"). However, the Board has approved an amendment to the
Certificate of Incorporation of the Company, a copy of which is attached hereto
as Exhibit H (the "Certificate Amendment"). which would, among other things,
increase the number of authorized shares of Common Stock and Preferred Stock to
500,000 and 200,000, respectively, and permit the Board to fix the terms of the
Preferred Stock. Assuming that all Shares are subscribed for and that the equity
transactions with the Enron Entity close on or about the date that the sale of
the Shares is consummated, the Company anticipates that 97,067.30 shares of
Common Stock and 10,000 shares of Series B Preferred Stock will be issued and
outstanding (not including 198.40 treasury shares held by the Company) and an
additional 26,266.57 shares of Common Stock will be reserved for issuance
pursuant to options, exclusive of options which may be granted under the
Incentive Option Plan, and pursuant to conversion of the Series B Preferred
Stock.

     The following summary description relating to the capital stock does not
purport to be complete. For a detailed description, reference is made to the
Certificate of Incorporation of the Company, as amended (the "Certificate"),
which is available at the Company for review.

Common Stock

     As of March 31, 1995, there were 83,706.19 shares of Common Stock
outstanding held of record by 51 stockholders (not including 156.40 treasury
shares then held by the Company). The holders of Common Stock are entitled to
one vote for each share held of record on all matters submitted to a vote of the
stockholders. Subject to preferential rights with respect to Preferred Stock
which may be issued, holders of Common Stock are entitled to receive ratably
such dividends as may be declared by the Board out of legally available funds.
In the event of a liquidation, dissolution, sale or winding up of the Company,
holders of Common Stock are entitled to share ratably in all assets remaining
after payment of liabilities and satisfaction of preferential rights and have no
rights to convert their Common Stock into any other securities. Holders of
Common Stock have no preemptive or subscription rights unless (i) they are a
party to the Gale Force Stockholders' Agreement, the 1993 Stockholders'
Agreement or the 1995 Management Stockholders' Agreement or (ii) they become a
party to the Stockholders' Agreement, and then only to the extent provided in
each such agreement. See "Principal Stockholders - Stockholders' Agreements" and
"The Offering - Stockholders' Agreement - Preemptive Rights." There are no
redemption or conversion rights with respect to any shares of Common Stock. The
outstanding shares of Common Stock are, and the Common Stock to be outstanding
upon completion of the offering will be, fully paid and nonassessable.

Preferred Stock

     The Company currently has no shares of Preferred Stock outstanding. The
Board has the authority to cause the Company to issue without any further vote
or action by the stockholders, up to the authorized number of shares of
Preferred Stock in one or more series, to designate the number of shares
constituting any series, and to fix the rights, preferences, privileges and

                                      54
<PAGE>

restrictions thereof, including dividend rights, conversion rights, voting
rights, rights and terms of redemption, redemption price or prices and
liquidation preferences of such series. The Company is currently contemplating
issuing shares of Preferred Stock at or about the time of this offering in
accordance with the Series B Preferred Stock Issuance and the Series A Preferred
Stock Issuance. See "Certain Contemplated Transactions."

Options

     The Company currently has outstanding options to purchase 172.5 shares of
Common Stock at $1.00 per share. All such options were issued to certain
executive officers in connection with the 1992 Stock Plan. The options expire at
various times in 2007.

     The Company currently has outstanding options to purchase 2,364.5 shares of
Common Stock at $725 per share. Of these options, 850.5 were issued to certain
executive officers in connection with the 1992 Stock Plan, and 1,514 were issued
to certain members of the Company's management in connection with the 1993
Option Plan. The options issued pursuant to the 1992 Stock Plan expire at
various times in 2007, and the options issued pursuant to the 1993 Option Plan
expire on June 29, 2003.

     The Company currently has outstanding options to purchase 2,583-89 shares
of Common Stock at $833.75 per share. All such options were issued to certain
executive officers in connection with the Senior Executive Plan. 1,937.92 of
such options will expire June 29, 2003 and 645.97 of such options will expire
May 15, 2005.

     The Company currently has outstanding options to purchase 83.33 shares of
Common Stock at $1,100 per share. All such options were granted under the 1995
Management Option Plan and will expire on July 7, 2005.

     As long as the options remain unexercised and outstanding, the holders
thereof will have the opportunity to profit from an increase in the value of the
Common Stock, if any, without assuming the risk of ownership.

Special Provisions of the Certificate of Incorporation and Delaware Law

Limitation of Director Liability

     Section 102(b)(7) of the Delaware General Corporation Law ("Section
102(b)") authorizes corporations to limit or eliminate the personal liability of
directors to corporations and their stockholders for monetary damages for breach
of directors' fiduciary duty of care. Although Section 102(b) does not change
directors' duty of care, it enables corporations to limit available relief to
equitable remedies such as injunction or rescission. The Company's Certificate
of Incorporation limits the liability of directors to the Company or its
stockholders (in their capacity as directors but not in their capacity as
officers) to the fullest extent permitted by Section 102(b). Specifically,
directors of the Company will not be personally liable for monetary damages for
breach of a director's fiduciary duty as a director, except for liability (i)
for any breach of the director's duty of loyalty to the Company or its
stockholders (ii) for acts or omissions not in

                                      55
<PAGE>

good faith or which involve intentional misconduct or a knowing violation of
law, (iii) for unlawful payments of dividends or unlawful stock repurchases or
redemptions as provided in Section 174 of the Delaware General Corporation Law
or (iv) for any transaction from which the director derived an improper personal
benefit. The Certificate Amendment, if and when filed with the Secretary of
State of the State of Delaware, will provide for mandatory indemnification of
directors and officers of the Company and also would include a provision
regarding compromises or arrangements between the Company and its creditors.

Indemnification

     To the maximum extent permitted by law, the Company's Certificate of
Incorporation and Bylaws provide for mandatory indemnification of directors and
permit indemnification of officers, employees and agents of the Company against
all expense, liability and loss to which they may become subject or which they
may incur as a result of being or having been a director, officer, employee or
agent of the Company. In addition, the Company must advance or reimburse
directors, and may advance or reimburse officers, employees and agents for
expenses incurred by them in connection with indemnifiable claims.

                            ADDITIONAL INFORMATION

     The Company intends to supply its stockholders on an annual basis with a
copy of its audited financial statements.

     Each prospective investor and/or his purchaser or other representatives are
hereby granted access to, and are invited to review, all materials available to
the Company relating to this offering or anything set forth in this Offering
Memorandum.

     The Company will answer all inquiries from prospective investors or their
representatives relating to the transactions contemplated hereunder and will
afford prospective investors and their representatives the opportunity to obtain
any additional information (to the extent that the Company possesses such
information or can acquire it without unreasonable effort or expense) necessary
to verify the accuracy of the information set forth in this Offering Memorandum.

     Each prospective investor should use this opportunity to communicate
directly with his own legal counsel, accountants and other professional advisors
who can help the prospective investor evaluate the merits and risks of a
purchase of the Shares and the tax and legal aspects thereof.

to the conditions of this Agreement, the Company shall deliver to Purchaser

shall retain possession of all of the Shares in accordance with the terms of the
Pledge Agreement, (ii) a copy of the fully executed Stockholders' Agreement (the
original of which will be retained at the offices of the Company) and (iii) a
fully executed counterpart of Purchaser's Option Agreement.

        5. Representations and Warranties of Purchaser. Purchaser hereby
represents and warrants to the Company as follows:

                (a) Investment Intention; No Resales. Purchaser is acquiring the
        Shares for investment solely for his own account and not with a view to,
        or for resale in connection with, the distribution or other disposition
        thereof. Purchaser agrees and acknowledges that all dispositions of the
        Shares by Purchaser (other than involuntary transfers) will comply with
        the provisions of this Agreement, the provisions of the Stockholders'
        Agreement and the Pledge Agreement and applicable provisions of state
        and federal securities laws.

                (b) Certain Information Not Material. Purchaser has not received
        individualized information relative to the compensation of the
        management of the Company, which information is acknowledged by
        Purchaser as not being material to Purchaser in forming a basis for
        making an investment in the Shares or for any other purpose in
        connection herewith.

                (c) Shares Unregistered. Purchaser acknowledges and represents
        that he has been advised by the Company that:

                (i) the offer and sale of the Shares have not been registered
        under the Securities Act of 1933, as amended (the "Securities Act"), or
        any state securities laws;

                                       3
<PAGE>

                (ii) the Shares must be held indefinitely and Purchaser must
        continue to bear the economic risk of the investment in the Shares
        unless the offer and sale of such Shares is subsequently registered
        under the Securities Act and all applicable state securities laws or an
        exemption from such registration is available;

                (iii) there is no established market for the Shares and it is
        not anticipated that there will be any public market for the Shares in
        the foreseeable future;

                (iv) the Company is under no obligation to register under the
        Securities Act the Shares on behalf of Purchaser, to assist Purchaser in
        complying with any exemption from registration or to consent to the
        transfer of the Shares;

                (v) Rule 144 promulgated under the Securities Act may not be
        presently available with respect to the sale of any securities of the
        Company, and the Company has made no covenant to make such Rule
        available ;

                (vi) when and if the Shares may be disposed of without
        registration under the Securities Act in reliance on Rule 144, such
        disposition may be made only in limited amounts in accordance with the
        terms and conditions of such Rule;

                (vii) a restrictive legend in the form hereafter set forth shall
        be placed on the certificates representing the Shares; and

                (viii) a notation shall be made in the appropriate records of
        the Company indicating that the Shares are subject to restrictions on
        transfer and appropriate stop-transfer instructions will be issued with
        respect to the Shares.

                (d)  Additional Investment Representations.

                (i) Purchaser has carefully reviewed, is familiar with and
        understands the Memorandum, the Stockholders' Agreement, the Four Year
        Note, the Pledge Agreement, the Option Agreement and the other
        documents, records and information, if any, requested by Purchaser or
        otherwise supplied by the Company in connection with the Offering;

                (ii) All documents, records and information pertaining to an
        investment in the Company which have been requested by Purchaser have
        been made available or delivered to Purchaser, except to the extent
        otherwise addressed in the Memorandum;

                (iii) Purchaser is fully familiar with the business and
        operations of the Company and has had an opportunity to ask questions of
        and receive answers from the Company concerning the terms and conditions
        of his investment and the financial condition, operations and prospects
        of the Company;

                (iv) No oral or written statement, printed material or
        inducement given or made by the Company or any of the Company's
        affiliates is contrary to the information contained in this Agreement,
        the Memorandum, the Stockholders' Agreement, the Four

                                       4
<PAGE>

        Year Note or the Pledge Agreement, and Purchaser acknowledges and agrees
        that in making his decision to purchase the Shares he has relied solely
        on such documents and the independent investigations made by him and, to
        the extent believed by Purchaser to be appropriate, his representatives,
        including his own professional, financial, legal, tax and other
        advisors;

                (v) Purchaser acknowledges that the Company, in reliance upon
        certain federal and state securities law exemptions, has provided
        Purchaser with less or different information than Purchaser would have
        received if an information memorandum complying with Rule 502(b)(2) of
        Regulation D promulgated pursuant to the Securities Act had been
        prepared and made available to Purchaser or if the Shares had been
        registered pursuant to the Securities Act. The foregoing
        notwithstanding, the information provided to Purchaser is sufficient to
        allow Purchaser to make a knowledgeable and informed decision regarding
        his investment in the Shares;

                (vi) Purchaser (A) has adequate means of providing for his
        current financial needs and possible personal contingencies and has no
        need for liquidity in his investment in the Shares, (B) can bear the
        economic risk of losing his entire investment in the Shares, (C) has
        such knowledge and experience in financial matters that he is capable of
        evaluating the relative risks and merits of his purchase of the Shares,
        (D) is familiar with the nature of, and risks attendant to, his purchase
        of the Shares, and (E) has determined that the purchase of the Shares is
        consistent with Purchaser's financial objectives;

                (vii) Purchaser realizes that he may not be able to sell or
        dispose of the Shares even in the event of a personal emergency.
        Purchaser's overall commitment to investments which are not readily
        marketable (including his investment in the Shares) is not
        disproportionate to his net worth;

                (viii) The address set forth on the signature page hereof is
        Purchaser's true and correct residence, and Purchaser has no present
        intention of becoming a domiciliary of any other state or jurisdiction;

                (ix) Purchaser has no reason to anticipate any change in his
        circumstances, financial or otherwise, which may cause or require any
        sale or disposition by him of any of the Shares;

                (x) Each of this Agreement and the Stockholders' Agreement has
        been duly and validly executed and delivered by Purchaser and each
        constitutes the valid and binding obligation of Purchaser enforceable
        against him, his successors and assigns, including, but not limited to,
        his estate and his spouse, in accordance with its terms;

                (xi) Assuming the due execution and delivery of each of this
        Agreement and the Stockholders' Agreement by the Company, each of this
        Agreement and the Stockholders' Agreement is a valid and binding
        obligation of the Purchaser, enforceable against the Purchaser in
        accordance with its terms, except as such enforcement may be subject to
        (A) bankruptcy, insolvency, reorganization, moratorium

                                       5
<PAGE>

        or other similar laws now or hereafter in effect relating to creditors
        rights generally and (B) general principles of equity (regardless of
        whether such enforcement is considered in a proceeding in equity or at
        law); and

                (xii) The Company has not guaranteed, represented or warranted
        to Purchaser either that (A) the Company will be profitable or that
        Purchaser will realize profits, as a result of his investment in the
        Shares or (B) the past performance or experience on the part of any
        officer, director, stockholder, employee, agent, representative or
        affiliate thereof, or any employee, agent, representative or affiliate
        of the Company will in any way indicate the predictable results of
        ownership of the Shares.

        (e)  Residence-Specific Representations.

                (i) If Purchaser is a resident of the State of Texas or the
        State of Arkansas, the aggregate Purchase Price for the Shares
        subscribed for by Purchaser hereunder does not exceed 20% of Purchaser's

                (a) Organization; Qualification. The Company is a corporation
        duly organized, validly existing and in good standing under the laws of
        the State of Delaware. The Company is duly qualified and in good
        standing as a foreign corporation and is licensed, admitted or approved
        to do business as a foreign corporation in each jurisdiction wherein the
        character of the properties owned or held under lease by it, or the
        nature of the business conducted by it, makes such qualification
        necessary, except where the failure to qualify would not have a material
        adverse effect on the Company, and would not have any adverse effect on
        the enforceability of this Agreement.

                (b) Authority. The Company has the requisite corporate power and
        authority and full legal right to enter into this Agreement, to perform,
        observe and comply with all of its agreements and obligations hereunder
        and to issue the Shares to Purchaser.

                (c) Due Authorization. The execution and delivery by the Company
        of this Agreement, the performance by it of all of its agreements and
        obligations under this

        Agreement and the Option Agreement, and the issuance of the Shares, have
        been duly authorized by all necessary corporate action on the part of
        the Company.

                (d) Binding Obligation. This Agreement, the Stockholders'
        Agreement and the Option Agreement have each been duly and validly
        executed and delivered by the Company, and, assuming the due execution
        and delivery of each such document by Purchaser, each is a valid and
        binding obligation of the Company, enforceable against the Company in
        accordance with its terms, except as such enforcement may be subject to
        (i) bankruptcy, insolvency, reorganization, moratorium or other similar
        laws now or hereafter in effect relating to creditors' rights generally
        and (ii) general principles of equity (regardless of whether such
        enforcement is considered in a proceeding in equity or at law).

                (e) Capitalization. At the Closing Date, the authorized capital
        stock of the Company will consist of 500,000 shares of Common Stock and
        200,000 shares of preferred stock. No other class or series of capital
        stock of the Company is authorized. All of the outstanding shares of
        Common Stock, including the Shares, will, at the time of issuance, have
        been duly authorized and issued and, upon receipt by the Company of the
        Purchase Price for the Shares subscribed for hereunder will be fully
        paid and non-assessable. There are no pre-emptive rights relating to the
        capital stock of the Company other than those granted pursuant to (i)
        the Stockholders' Agreement, (ii) that certain Stockholders' Agreement,
        dated as of June 29, 1993, among the Company and certain of its
        stockholders (iii) that certain Stockholders' Agreement, dated as of
        March 8, 1995, among the Company and certain of its stockholders, and
        (iv) that certain Stockholders' Agreement, dated as of July 7, 1995,
        among the Company and certain of its stockholders.

                (f) Legend. Each certificate representing the Shares shall bear
        a legend substantially to the following effect:

                        THE SHARES OF COMMON STOCK REPRESENTED BY THIS
                CERTIFICATE HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF

                ACT OF 1933 AND ANY APPLICABLE STATE SECURITIES LAWS OR AN
                OPINION OF COUNSEL TO THE COMPANY THAT SUCH REGISTRATION IS NOT
                REQUIRED. IN ADDITION, THE SALE, TRANSFER, PLEDGE OR OTHER
                DISPOSITION OF THE SHARES EVIDENCED BY THIS CERTIFICATE IS

        10.  Indemnification.

        (a) Indemnification of the Company and the Company Affiliates. From and
after the date hereof, Purchaser shall indemnify and hold harmless the Company
and its predecessors, successors, officers, directors, employees,
representatives and agents (collectively, the "Indemnitees") from and against
any loss, damage or expense, including, without limitation, reasonable
attorneys' and consultants' fees, disbursements and expenses, suffered by any
one or more of the Indemnitees arising out of or resulting from any inaccuracy
in or breach of any of the representations, warranties, covenants or agreements
made by Purchaser herein.

        (b) Indemnification of Purchaser. From and after the date hereof, the
Company shall indemnify and hold harmless Purchaser from and against any loss,
damage or expense, including, without limitation, reasonable attorneys' and
consultants' fees, disbursements and expenses suffered by Purchaser arising out
of or resulting from any inaccuracy in or breach of any of the representations,
warranties, covenants or agreements made by the Company herein.

        (c) Procedure for Claims. Within thirty days after obtaining written
notice of any claim or demand which has given rise to, or could reasonably give
rise to, a claim for indemnification hereunder, the party seeking
indemnification shall give written notice of such claim ("Notice of Claim") to
the other party. The Notice of Claim shall set forth a brief description of the
facts giving rise to such claim and the amount (or a reasonable estimate) of the
loss, damage or expense suffered, or which may be suffered, by the party seeking
indemnification.

        Upon receiving the Notice of Claim, the indemnifying party shall resist,
settle or otherwise dispose of such claim in such manner as it shall deem
appropriate, including the employment of counsel, and shall be responsible for
the payment of all expenses, including the reasonable fees and expenses of such
counsel.  The indemnified party shall have the right to employ separate counsel
in any such action and to participate in or assume the defense thereof, but the
fees and expenses of such counsel shall be at the indemnified party's expense
unless (i) the employment has been specifically authorized by the indemnifying
party in writing, (ii) the indemnifying party has failed to assume the defense
and employ counsel in a timely manner or (iii) the named parties to any action
(including any impleaded parties) include both Purchaser and the Company, and
the indemnified party has been advised by such counsel that representation of
the Company and the Purchaser by the same counsel would be inappropriate under
applicable standards of professional conduct due to actual or potential
differing interests between them (in which case, if the indemnified party
notifies the indemnifying party in writing that the indemnified party elects to
employ separate counsel at the expense of the indemnifying party, the
indemnifying party shall have neither the right nor the obligation to assume the
defense of such action on behalf of the indemnified party).

        (d) Third Party Beneficiaries. Nothing contained in this Section 10
shall confer any rights upon, or inure to the benefit of, any third party other
than those parties specified in Sections 10(a) and 10(b) above, it being
understood that such specified parties, to the extent not actually parties
hereto, shall be third party beneficiaries.
