                             STOCKHOLDERS AGREEMENT

                              AMENDED AND RESTATED
                             INSTRUMENT OF ACCESSION

         This AMENDED AND RESTATED INSTRUMENT OF ACCESSION (the "Instrument of
Accession"), is executed by Energy Spectrum Partners LP, a Delaware limited
partnership ("Energy"), and Universal Compression Holdings, Inc., a Delaware
corporation ("Holdings").

                                    RECITALS

         As of April 28, 2000 (the "Effective Date"), Energy executed and
delivered an Instrument of Accession (the "Original Instrument of Accession") as
a condition precedent to becoming the owner or holder of record of seventeen
thousand two hundred and one (17,201) shares of Common Stock, par value $0.01
per share, of Holdings and sixty eight thousand eight hundred and four (68,804)
shares of Preferred Stock, par value $0.01 per share, of Holdings.

         Energy and Holdings hereby agree that the Original Instrument of
Accession is hereby amended and restated in its entirety as follows:

         As of the Effective Date, Energy agrees to become a stockholder, party
to and bound by that certain Stockholders Agreement, dated as of February 20,
1998, by and among Holdings and certain stockholders of Holdings (the
"Stockholders Agreement"). In connection therewith, if Holdings shall not have
consummated a public offering of equity securities that are registered under the
Securities Act of 1933, as amended, prior to or on August 31, 2000, Holdings
hereby grants to Energy, from and after August 31, 2000, upon the terms and
conditions as set forth herein, the following Board of Directors observer rights
(the "Board Observer Rights"):

                  Energy may select a representative to attend as an observer
         all meetings, including telephonic meetings, of Holdings' Board of
         Directors. In such event, Holdings will give Energy written notice of
         each meeting of its Board of Directors at the same time and in the same
         manner as notice is given to the directors. Energy shall also be
         provided with all written materials and other information (including
         minutes of meetings) given to directors in connection with such
         meetings at the same time such materials and information are given to
         the directors. If Holdings proposes

<PAGE>   2

         to take any action by written consent in lieu of a meeting of its Board
         of Directors, Holdings shall give written notice thereof to Energy
         promptly following the effective date of such consent describing in
         reasonable detail the nature and substance of such action. In the event
         Holdings establishes separate committees of the Board of Directors, the
         right to a representative granted hereunder shall extend to all
         meetings, including telephone meetings, of the Compensation and Audit
         Committees, but shall in no event extend to meetings of Holdings'
         Executive Committee. The Board Observer Rights are exclusive to Energy
         and are thereby not assignable by Energy under any circumstances. The
         Board Observer Rights shall terminate concurrently with, and upon the
         same terms and conditions, as the Board of Directors observer rights
         set forth in Section 8.8 of the Stockholders Agreement.

         This Amended and Restated Instrument of Accession shall be effective as
of the Effective Date and, except for the Board Observer Rights, shall be an
integral part of the Stockholders Agreement as of the Effective Date immediately
upon execution by the undersigned parties.

                            [Signature page follows.]

         1. Sections 2(b)(ii) and (iii) of the Prior Option Agreement are
amended to provide as follows:

                           (ii) Termination of Employment Without Cause. In the
         event Universal terminates Employee's employment without Cause (as
         defined in the Plan), the Option shall terminate as of the date of
         Employee's termination of employment except for the portion of the
         Option which is exercisable as of the date of termination of

         Option, whether or not exercisable as of the date of termination of
         employment, shall terminate in its entirety on the date of termination.

         2. Section 4 of the Prior Option Agreement is amended to provide as

         Exercise Price of the Option being exercised; (iv) by any combination
         of (i), (ii) and (iii); or (v) with the consent of the Administrator of
         the Plan, which consent may be given or withheld in its sole

         3. Section 8 of the Prior Option Agreement is amended to provide as
follows:

                  8. ADJUSTMENT. The number, class of and/or Exercise Price of
         shares subject to the Option shall be adjusted by the Administrator of
         the Plan to reflect a change in the capitalization of Holdings
         resulting from a stock dividend or split, and may be adjusted by the
         Administrator of the Plan to reflect a change in the capitalization of
         Holdings resulting from a merger, consolidation, acquisition,
         separation (including a spin-off or spin-out), reorganization or
         liquidation; provided that the number of shares subject to the Option
         shall always be a whole number. Notwithstanding the foregoing, the
         issuance by Holdings of shares of any class or securities convertible
         into shares of any class, for cash or property, or for labor or
         services, either upon direct sale or upon exercise of rights or
         warrants to subscribe therefor, or upon conversion of shares or
         obligations of Holdings convertible into such shares or other
         securities, shall not affect, and no adjustment by reason thereof shall
         be made with respect to the shares subject to the Option.

                                       II.

         2. As amended, Section 10(d) of the Plan will provide as follows:

                  (d) Payment of Option Price Upon Exercise. The purchase price

         Administrator, by delivery of shares of Common Stock owned by the
         Participant having a Fair Market Value (as defined and determined by
         Section 2 hereof) equal in amount to the aggregate exercise price of
         the Option being exercised; (iv) by any combination of (i), (ii) and
         (iii); or (v) with the consent of the Administrator, by cancellation of
         a portion of the Option as determined by the Administrator.

         which may be available for the grant of Options and the number, class

         capitalization of the Corporation resulting from a stock dividend or
         split, and may be adjusted by the Administrator to reflect

                                       3
<PAGE>   4

         a change in the capitalization of the Corporation resulting from a
         merger, consolidation, acquisition, separation (including a spin-off or
         spin-out), reorganization or liquidation; provided that the number of
         shares subject to any Option shall always be a whole number.
         Notwithstanding the foregoing, the issuance by the Corporation of
         shares of any class or securities convertible into shares of any class,
         for cash or property, or for labor or services, either upon direct sale
         or upon exercise of rights or warrants to subscribe therefor, or upon
         conversion of shares or obligations of the Corporation convertible into
         such shares or other securities, shall not affect, and no adjustment by
         reason thereof shall be made with respect to, the shares authorized for
         issuance under Section 4 or the shares subject to outstanding Options.

                                      III.

                                NEW OPTION GRANT

         1. GRANT OF NEW OPTION. Holdings grants to the Employee an option (the
"Option") to purchase _______ shares of Common Stock at $______ per share
effective as of April 20, 2000. The Option shall expire on December 31, 2000
unless on or before such date (a) the Employee executes this Agreement and
Consent and (b) there is an initial public offering of Common Stock. If both (a)
and (b) occur on or before December 31, 2000, the Option shall expire at 12:00
midnight on April 19, 2010, unless sooner terminated under the provisions
hereof. This Option is granted under the Plan, as amended April 20, 2000, a copy
of which is attached hereto as Exhibit "A" and is incorporated herein by
reference, and shall constitute an Incentive Stock Option under Section 422 of
the Internal Revenue Code of 1986, as amended, (the "Code") to the extent
permissible under Section 422(d) of the Code, and otherwise shall be a
Non-qualified Stock Option. All capitalized terms not otherwise defined in this
Agreement and Consent shall have the respective meaning of such terms as defined
in the Plan.

         2. OPTION TERMS AND CONDITIONS.

         (a) Exercise of Option. The Option shall become exercisable based on
the same vesting schedule and dates as set forth in Section 2(a) of the Prior
Option Agreement; provided, however, the Option shall become immediately
exercisable (except as provided in this sentence below) upon (i) a public
offering of Common Stock of Holdings, (ii) the acquisition by any Person, other
than an Affiliate of Castle Harlan Partners III, L.P. (as defined in the Plan)
of fifty-one percent (51%) or more of the Common Stock of Holdings, or (iii) a
sale of all or substantially all of the assets of Holdings; provided further
that, notwithstanding the foregoing, in no event may the Option be exercisable
prior to the later of: (x) the Employee's execution of this Agreement and
Consent and (y) an initial public offering of Common Stock, and if neither of
such events occurs on or before December 31, 2000, this Option shall terminate
as provided in Section 1 above.

         (b) Termination of Employment.

                  (i) Termination due to Death, Disability or Retirement. In the
event the Employee's employment with Universal terminates on account of death,
Disability (as defined in

                                       4
<PAGE>   5

the Plan) or retirement after age 65, the Option shall terminate as of the date
of Employee's termination of employment, except for the portion of the Option
which is exercisable as of the date of termination of employment, which shall
terminate three months following the date of Employee's death, disability or
retirement after age 65.

                  (ii) Termination of Employment Without Cause. In the event
Universal terminates Employee's employment without Cause (as defined in the
Plan), the Option shall terminate as of the date of Employee's termination of
employment except for the portion of the Option which is exercisable as of the
date of termination of employment, which shall terminate 30 days following the
date of such termination of employment.

                  (iii) Termination of Employment for Cause or Voluntary
Resignation. In the event the Employee's employment with Universal shall
terminate for Cause (as defined in the Plan), or the Employee voluntarily
resigns his or her employment with Universal, the Option, whether or not
exercisable as of the date of termination of employment, shall terminate in its
entirety on the date of termination.

         3. NON-TRANSFERABILITY. No Option granted hereby and no right arising
thereunder shall be transferable other than by will or by the laws of descent
and distribution. During the lifetime of the Employee, the Option shall be
exercisable only by the Employee. If the Option is exercisable at the date of
the Employee's death and is transferred by will or by the laws of descent and
distribution, the Option shall be exercisable in accordance with the terms of
such Option by the executor or administrator, as the case may be, of the
Employee's estate for a period of three (3) months after the date of the
Employee's death and shall then terminate.

         4. MODE OF EXERCISE. The Option shall be exercised by giving to
Holdings written notice stating (a) the number of shares with respect to which
the Option is being exercised, (b) the aggregate Exercise Price for such shares,
and (c) the method of payment. At the option of the Employee, such aggregate
Exercise Price may be paid: (i) in cash; (ii) with the consent of the Board,
which consent may be given or withheld in its sole discretion, by delivery of a
promissory note to Holdings payable over a three (3) year period and bearing
interest at the prime rate; (iii) with the consent of the Administrator of the
Plan, which consent may be given or withheld in its sole discretion, by delivery
of shares of Common Stock owned by the Employee having a Fair Market Value (as
determined by Section 5 below) equal in amount to the aggregate Exercise Price
of the Option being exercised; (iv) by any combination of (i), (ii) and (iii);
or (v) with the consent of the Administrator of the Plan, which consent may be
given or withheld in its sole discretion, by cancellation of a portion of the
Option as determined by the Administrator of the Plan.

         5. FAIR MARKET VALUE OF COMMON STOCK. The "Fair Market Value" of the
Common Stock on any day shall be determined by the Board as follows: (i) if the
Common Stock is listed on a national securities exchange or quoted through the
NASDAQ National Market System, the Fair Market Value on any day shall be the
average of the high and low reported Consolidated Trading sales prices, or if no
such sale is made on such day, the average of the closing bid and asked prices
reported on the Consolidated Trading listing for such day; (ii) if the Common
Stock is quoted on the NASDAQ inter-dealer quotation system, the Fair Market

                                       5

Value on any day shall be the average of the representative bid and asked prices
at the close of business for such day; (iii) if the Common Stock is not listed
on a national stock exchange or quoted on NASDAQ, the Fair Market Value on any
day shall be the average of the high bid and low asked prices reported by the
National Quotation Bureau, Inc. for such day; or (iv) if none of clauses (i) -
(iii) are applicable, the Fair Market Value as may be determined by the Board or
the Administrator of the Plan, there being no obligation to make such
determination.

         6. STOCK CERTIFICATES. All stock certificates representing shares of
Common Stock acquired pursuant to the exercise of an Option that are issued by
Holdings shall contain a legend substantially in the following form:

                "SHARES OF UNIVERSAL COMPRESSION HOLDINGS, INC. ("HOLDINGS")
       REPRESENTED BY THIS CERTIFICATE ARE SUBJECT TO A STOCKHOLDERS AGREEMENT,
       DATED AS OF February 20, 1998, AS MAY BE AMENDED, WHICH CONTAINS
       PROVISIONS REGARDING THE RESTRICTIONS ON THE TRANSFER OF SUCH SHARES AND
       OTHER MATTERS. A COPY OF SUCH AGREEMENT IS AVAILABLE FOR INSPECTION AT
       THE PRINCIPAL OFFICE OF HOLDINGS. THE SHARES REPRESENTED BY THIS
       CERTIFICATE WERE NOT REGISTERED UNDER, AND ARE SUBJECT TO, THE SECURITIES
       ACT OF 1933, AS AMENDED (THE "SECURITIES ACT"), AND MAY NOT BE SOLD,
       TRANSFERRED OR ASSIGNED EXCEPT PURSUANT TO AN EFFECTIVE REGISTRATION
       UNDER THE SECURITIES ACT OR IN A TRANSACTION EXEMPT FROM REGISTRATION
       UNDER THE SECURITIES ACT."

         In the event that the shares of Common Stock issued pursuant to the
Option are (i) registered under the Securities Act of 1933, as amended (the
"Securities Act"), pursuant to an effective registration statement which
complies with the then applicable regulations, rules and procedures and
practices of the Securities and Exchange Commission, and are registered and/or
qualified in accordance with any applicable state laws, regulations, rules and
administrative procedures practices, or (ii) transferred pursuant to an
exemption from registration under the Securities Act and, at the request of
Holdings, Holdings has received an executed legal opinion, satisfactory to its
counsel, as to the availability of and compliance with such exemption and that
such shares need not bear the restrictive legend stating that such shares have
not been registered under the Securities Act, Holdings may issue new
certificates representing such shares omitting that portion of such restrictive
legend.

         The shares of Common Stock acquired pursuant to the Option shall be
subject to the provisions regarding transfers of shares in the Stockholders
Agreement dated as of February 20, 1998, among Holdings and the partners named
on the signature pages thereto, as amended from time to time (the "Stockholders
Agreement"). At the request of Holdings, the Employee shall become a party to
the Stockholders Agreement prior to the issuance of any shares under this
Agreement and Consent.

         In the event the Stockholders Agreement terminates, certificates
representing the shares of Common Stock issued pursuant to the Option may be
issued omitting that portion of the

                                       6
<PAGE>   7

restrictive legend stating that such shares are subject to the Stockholders
Agreement and the availability of a copy of such agreement.

         7. OPTION SUBJECT TO SECURITIES AND OTHER REGULATIONS. The Option
granted hereunder and the obligation of Holdings to sell and deliver shares
under such Option shall be subject to all applicable federal and state laws,
rules and regulations and to such approvals by any government or regulatory
agency as may be required. Holdings, in its discretion, may postpone the
issuance or delivery of shares upon any exercise of the Option until completion
of any stock exchange listing, or other qualification of such shares under any
state or federal law, rule or regulation as Holdings may consider appropriate,
and may require the Employee, his beneficiary or his legal representative to
make such representations and furnish such information as it may consider
appropriate in connection with the issuance or delivery of the shares in
compliance with applicable laws, rules and regulations.

         Upon demand by the Board, the Employee (or any person acting under
Section 3 above) shall deliver to the Board at the time of exercise of the
Option a written representation that the shares to be acquired upon the exercise
of the Option are being acquired for his own account and not with a view to, or
for resale in connection with, any distribution in violation of federal or state
securities laws. Upon such demand, delivery of such representation prior to the
delivery of any shares issued upon exercise of the Option shall be a condition
precedent to the right of the Employee or such other person to purchase any
shares.

         8. BUYBACK RIGHT. Upon any termination of the employment of the
Employee prior to a public offering of Common Stock, Holdings or its designee
may at its option purchase all Common Stock acquired upon any exercise of the
Option then held by the Employee for a purchase price equal to the determined
value of such stock at the time of purchase. For purposes of this Section 8,
"determined value" shall mean the determined value of the shares of Common Stock
being purchased by Holdings pursuant to this Section 8, such value to be
determined annually as of March 31 of each year by a nationally recognized
investment banking or appraisal firm selected by Holdings. This valuation will
serve as the determined value for the shares until the next valuation unless the
Board determines that a significant change in Holdings performance or prospects
requires a revaluation of the shares.

         The purchase by Holdings pursuant to this Section 8 shall be paid for
in cash, to the extent permitted under the loan agreements and debt instruments
relating to Holdings or any of its subsidiaries, or, to the extent cash payments
are not permitted thereunder, by means of a subordinated payment-in-kind
promissory note issued by Holdings bearing interest, payable annually, at the
lowest interest rate required to avoid imputed interest, which note shall be
repaid as soon as permitted.

         9. NO RIGHTS AS STOCKHOLDER PRIOR TO EXERCISE OF OPTION. The
Participant shall not have any rights as a stockholder with respect to any
shares subject to the Option prior to the date on which the Employee is recorded
as the holder of such shares on the records of Holdings.

         10. NO RIGHTS WITH RESPECT TO CONTINUANCE OF EMPLOYMENT. Neither the
grant of the Option nor any action taken with respect thereto shall be construed
as giving the Employee the right to be retained in the employ of Universal or
any subsidiary or affiliate, nor shall it interfere in any way with the right of
Universal or any such subsidiary or affiliate to terminate any Employee's
employment at any time for any reason, or for no reason at all.

         11. TAXES. Holdings may make such provisions and take such steps as it
may deem necessary or appropriate for the withholding of all Federal, state,
local and other taxes required by law to be withheld with respect to the Option
including, but not limited to: (i) reducing the number of shares of Common Stock
otherwise deliverable, based upon their Fair Market Value on the date of
exercise, to permit deduction of the amount of any such withholding taxes from
the amount otherwise payable under this Agreement and Consent; (ii) deducting
the amount of any such withholding taxes from any other amount then or
thereafter payable to the Employee; or (iii) requiring the Employee, his
beneficiary or his legal representative to pay to Holdings the amount required
to be withheld or to execute such documents as Holdings deems necessary or
desirable to enable it to satisfy its withholding obligations as a condition of
releasing the Common Stock.

         12. GOVERNING LAW. This Agreement and Consent shall be governed and
construed in accordance with the laws of the State of Delaware applicable to
contract made and to be performed entirely within such state.

         13. COUNTERPARTS. This Agreement and Consent may be executed in two or
more counterparts, each of which shall be deemed an original, but all of which
shall constitute one and the same instrument, and it shall not be necessary in
making proof of this Agreement and Consent to produce or account for more than
one such counterpart.

         14. NOTICES. Any notice or other communication required or which may be
given hereunder shall be in writing and shall be delivered personally,
telecopied with confirmed receipt, sent by certified, registered, or express
mail, postage prepaid, or sent by a national next-day delivery service to the
parties at the following addresses or at such other addresses as shall be
