banking corporation, as trustee (the "Guarantee Trustee"), for the benefit of
the Holders (as defined herein) from time to time of the Preferred Securities
(as defined herein) of Hanover Compressor Capital Trust, a Delaware statutory

     WHEREAS, pursuant to an Amended and Restated Declaration of Trust (the

     WHEREAS as incentive for the Holders to purchase the Preferred Securities,
the Guarantor desires irrevocably and unconditionally to agree, to the extent

defined herein) except that if a Debenture Event of Default or a Declaration

time, would become such a Debenture Event of Default) shall have occurred and be
continuing, the rights of holders of the Common Securities to receive Guarantee
Payments under the Common Securities Guarantee are subordinated to the rights of
Holders to receive Guarantee Payments under this Guarantee.

     NOW, THEREFORE, in consideration of the purchase by each Holder of
Preferred Securities, which purchase the Guarantor hereby agrees shall benefit

Guarantee Trustee, the Guarantee Trustee shall exercise such of the rights and
powers vested in it by this Guarantee, and use the same degree of care and skill
in its exercise thereof, as a prudent person would exercise or use under the

Guarantee Trustee from liability for its own negligent action, its own negligent
failure to act, or its own willful misconduct, except that:

               (i) prior to the occurrence of any Event of Default and after the

          such duties and obligations as are specifically set forth in this
          Guarantee, and no implied covenants or obligations shall be read into
          this Guarantee against the Guarantee Trustee; and

               (B) in the absence of bad faith on the part of the Guarantee
          Trustee, the Guarantee Trustee may conclusively rely, as to the truth
          of the statements and the correctness of the opinions expressed
          therein, upon any certificates or opinions furnished to the Guarantee
          Trustee and conforming to the requirements of this Guarantee; but in
          the case of any such certificates or opinions that by any provision
          hereof are specifically required to be furnished to the Guarantee
          Trustee, the Guarantee Trustee shall be under a duty to examine the
          same to determine whether or not they conform to the requirements of
          this Guarantee;

               (ii) the Guarantee Trustee shall not be liable for any error of
     judgment made in good faith by a Responsible Officer of the Guarantee
     Trustee, unless it shall be proved that the Guarantee Trustee was negligent
     in ascertaining the pertinent facts upon which such judgment was made;

               (iii)  the Guarantee Trustee shall not be liable with respect to
     any action taken or omitted to be taken by it in good faith in accordance
     with the direction of the Holders of not less than a Majority in
     liquidation amount of the Preferred Securities, relating to the time,
     method and place of conducting any proceeding for any remedy available to
     the Guarantee Trustee, or exercising any trust or power conferred upon the
     Guarantee Trustee under this Guarantee; and

               (iv) no provision of this Guarantee shall require the Guarantee
     Trustee to expend or risk its own funds or otherwise incur personal
     financial liability in the performance of any of its duties or in the
     exercise of any of its rights or powers.

SECTION 3.02  Certain Rights of Guarantee Trustee.

          a)   Subject to the provisions of Section 3.01:

               (i) the Guarantee Trustee may conclusively rely and shall be

     may, in the absence of bad faith on its part, request and rely upon an
     Officers' Certificate which, upon receipt of such request, shall be
     promptly delivered by the Guarantor;

               (iv) the Guarantee Trustee shall have no duty to see to any
     recording, filing or registration of any instrument (or any rerecording,
     refiling or reregistration thereof);

               (v) the Guarantee Trustee may consult with legal counsel of its
     selection, and the written advice or opinion of such legal counsel with
     respect to legal matters shall be full and complete authorization and
     protection in respect of any action taken, suffered or omitted to be taken
     by it hereunder in good faith and in accordance with such advice or
     opinion. Such legal counsel may be legal counsel to the Guarantor or any of
     its Affiliates and may include any of the Guarantor's employees.  The
     Guarantee Trustee shall have the right at any time to seek instructions
     concerning the administration of this Guarantee from any court of competent
     jurisdiction;

               (vi) the Guarantee Trustee shall be under no obligation to
     exercise any of the rights or powers vested in it by this Guarantee at the

     Guarantee Trustee against the costs, expenses (including attorneys' fees
     and expenses) and liabilities that might be incurred by it in complying
     with such request or direction, including such reasonable advances as may
     be requested by the Guarantee Trustee; provided that nothing contained in
     this Section 3.02(a)(vi) shall be taken to relieve the Guarantee Trustee,
     upon the occurrence of an Event of Default known to the Guarantee Trustee,
     of its obligation to exercise the rights and powers vested in it by this
     Guarantee;

               (vii)  the Guarantee Trustee shall not be bound to make any
     investigation into the facts or matters stated in any resolution,
     certificate, statement, instrument, opinion, report, notice, request,
     direction, consent, order, bond, debenture, note, other evidence of
     indebtedness or other paper or document, but the Guarantee Trustee, in its
     discretion, may make such further inquiry or investigation into such facts
     or matters as it may see fit; the reasonable expense of every such
     investigation shall be paid by the Guarantor or, if paid by the Guarantee
     Trustee, shall be repaid by the Guarantor upon request, except any such
     expense  as may be attributable to the Guarantee Trustee's negligence or
     bad faith;

               (viii)  the Guarantee Trustee may execute any of the trusts or
     powers hereunder or perform any duties hereunder either directly or by or
     through agents or

     attorneys, and the Guarantee Trustee shall not be responsible for any
     misconduct or negligence on the part of any agent or attorney appointed
     with due care by it hereunder;

               (ix) any action taken by the Guarantee Trustee or its agents
     hereunder shall bind the Holders, and the signature of the Guarantee
     Trustee or its agents alone shall be sufficient and effective to perform
     any such action; it being understood that no third party shall be required
     to inquire as to the authority of the Guarantee Trustee to so act or as to
     its compliance with any of the terms and provisions of this Guarantee, both
     of which shall be conclusively evidenced by the Guarantee Trustee's or its
     agent's taking such action;

               (x) whenever in the administration of this Guarantee the
     Guarantee Trustee shall deem it desirable to receive instructions with
     respect to enforcing any remedy or right or taking any other action
     hereunder, the Guarantee Trustee (i) may request written instructions from
     the Holders or, other than with respect to enforcing any remedy or right or
     taking any action related thereto, the Guarantor, (ii) may refrain from
     enforcing such remedy or right or taking such other action until such
     written instructions are received, and (iii) shall be protected in acting
     in accordance with such written instructions; and

               (xi) the Guarantee Trustee shall not be charged with knowledge of
     any default or Event of Default hereunder unless a Responsible Officer of
     the Guarantee Trustee shall have knowledge of the default or Event of
     Default.

          (b) No provision of this Guarantee shall be deemed to impose any duty
or obligation on the Guarantee Trustee to perform any act or acts or exercise
any right, power, duty or obligation conferred or imposed on it, in any
jurisdiction in which it shall be illegal, or in which the Guarantee Trustee
shall be unqualified or incompetent in accordance with applicable law, to
perform any such act or acts or to exercise any such right, power, duty or
obligation. No permissive power or authority available to the Guarantee Trustee
shall be construed to be a duty.

SECTION 3.03  Not Responsible for Recitals or Issuance of Guarantee.

     The recitals contained in this Guarantee shall be taken as the statements
of the Guarantor, and the Guarantee Trustee does not assume any responsibility
for their correctness. The Guarantee Trustee makes no representations as to the

     The Guarantor agrees:

     (a) to pay the Guarantee Trustee from time to time such reasonable
compensation as the Guarantor and the Guarantee Trustee shall from time to time

shall not be limited by any provision of law in regard to the compensation of a
trustee of an express trust);

                                       9

     (b) except as otherwise expressly provided herein, to reimburse the
Guarantee Trustee upon its request for all reasonable expenses, disbursements
and advances incurred or made by the Guarantee Trustee in accordance with the
provisions of this Guarantee (including the reasonable compensation and expenses
of its agents and counsel), except any such expense, disbursement or advance as
may be attributable to its negligence or bad faith; and

     As security for the performance of the obligations of the Guarantor under
this Section 3.04, the Guarantee Trustee shall have a lien, prior to the
Preferred Securities, upon all the property and funds held or collected by the
Guarantee Trustee as such, except funds held in trust for the payment of
principal of, and premium (if any) or interest on, particular obligations of the
Guarantor under this Guarantee.

     The provisions of this Section 3.04 shall survive the termination of this
Guarantee.

 SECTION 4.01  Guarantee Trustee; Eligibility.

          (a) There shall at all times be a Guarantee Trustee which shall:

               (i) not be an Affiliate of the Guarantor; and

               (ii) be a corporation organized and doing business under the laws
     of the United States of America or any State or Territory thereof or of the

     trust powers, having a combined capital and surplus of at least 50 million
     U.S. dollars ($50,000,000), and subject to supervision or examination by
     Federal, State, Territorial or District of Columbia authority. If such
     corporation publishes reports of condition at least annually, pursuant to
     law or to the requirements of the supervising or examining authority
     referred to above, then, for the purposes of this Section 4.01(a)(ii), the
     combined capital and surplus of such corporation shall be deemed to be its
     combined capital and surplus as set forth in its most recent report of
     condition so published.

          (b) If at any time the Guarantee Trustee shall cease to be eligible to
so act under Section 4.01(a), the Guarantee Trustee shall immediately resign in
the manner and with the effect set out in Section 4.02(c).

          (c) If the Guarantee Trustee has or shall acquire any "conflicting
interest" within the meaning of Section 3.10(b) of the Trust Indenture Act, the

SECTION 4.02  Appointment, Removal and Resignation of Guarantee Trustee.

          (a) Subject to Section 4.02(b), the Guarantee Trustee may be appointed
or removed without cause at any time by the Guarantor.

          (b) The Guarantee Trustee shall not be removed in accordance with
Section 4.02(a) until a Successor Guarantee Trustee has been appointed and has
accepted such appointment by written instrument executed by such Successor
Guarantee Trustee and delivered to the Guarantor.

          (c) The Guarantee Trustee appointed to office shall hold office until
a Successor Guarantee Trustee shall have been appointed or until its removal or
resignation. The Guarantee Trustee may resign from office (without need for
prior or subsequent accounting) by an instrument in writing executed by the
Guarantee Trustee and delivered to the Guarantor, which resignation shall not
take effect until a Successor Guarantee Trustee has been appointed and has
accepted such appointment by instrument in writing executed by such Successor
Guarantee Trustee and delivered to the Guarantor and the resigning Guarantee
Trustee.

          (d) If no Successor Guarantee Trustee shall have been appointed and
accepted appointment as provided in this Section 4.02 within 60 days after
delivery to the Guarantor of an instrument of removal or resignation, the
Guarantee Trustee resigning or being removed may petition any court of competent
jurisdiction for appointment of a Successor Guarantee Trustee. Such court may
thereupon, after prescribing such notice, if any, as it may deem proper, appoint
a Successor Guarantee Trustee.

          (e) No Guarantee Trustee shall be liable for the acts or omissions to
act of any Successor Guarantee Trustee.

          (f) Upon termination of this Guarantee or removal or resignation of
the Guarantee Trustee pursuant to this Section 4.02, the Guarantor shall pay to

                                   Guarantee

SECTION 5.01  Guarantee.

     The Guarantor irrevocably and unconditionally agrees to pay in full on a
subordinated basis to the Holders the Guarantee Payments (without duplication of
amounts theretofore paid by or on behalf of the Issuer), as and when due, in
coin or currency of the United States of America which at the time of payment is
legal tender for payment of public and private debt regardless of any defense,
right of setoff or counterclaim that the Issuer may have or assert other than
the defense of payment. The Guarantor's obligation to make a Guarantee Payment
may be satisfied by direct payment of the required amounts by the Guarantor to
the Holders or by causing the Issuer to pay such amounts to the Holders.

                                       11
<PAGE>

SECTION 5.02  Subordination.

     If a Debenture Event of Default or a Declaration Event of Default (or an
event that, with passage of time, would become a Debenture Event of Default)
shall have occurred and be continuing, the rights of holders of the Common
Securities to receive Guarantee Payments under the Common Securities Guarantee
are subordinated to the rights of Holders to receive Guarantee Payments under
this Guarantee.

SECTION 5.03  Waiver of Notice and Demand.

     The Guarantor hereby waives notice of acceptance of this Guarantee and of
any liability to which it applies or may apply, presentment, demand for payment,
any right to require a proceeding first against the Issuer or any other Person
before proceeding against the Guarantor, protest, notice of nonpayment, notice
of dishonor, notice of redemption and all other notices and demands.

SECTION 5.04  Obligations Not Affected.

     The obligations, covenants, agreements and duties of the Guarantor under
this Guarantee shall in no way be affected or impaired by reason of the
happening from time to time of any of the following:

          (a) the release or waiver, by operation of law or otherwise, of the
performance or observance by the Issuer of any express or implied agreement,
covenant, term or condition relating to the Preferred Securities to be performed
or observed by the Issuer;

          (b) the extension of time for the payment by the Issuer of all or any
portion of the Distributions, the amount payable upon redemption or the amount
payable upon liquidation of the Issuer or any other sums payable under the terms
of the Preferred Securities or the extension of time for the performance of any
other obligation under, arising out of, or in connection with, the Preferred
Securities (other than an extension of time for payment of Distributions that
results from the extension of any interest payment period on the Debentures
permitted by the Indenture);

          (c) any failure, omission, delay or lack of diligence on the part of
the Holders to enforce, assert or exercise any right, privilege, power or remedy
conferred on the Holders pursuant to the terms of the TIDES, or any action on
the part of the Issuer granting indulgence or extension of any kind;

          (d) the voluntary or involuntary liquidation, dissolution, sale of any
collateral, receivership, insolvency, bankruptcy, assignment for the benefit of
creditors, reorganization, arrangement, composition or readjustment of debt of,
or other similar proceedings affecting, the Issuer or any of the assets of the
Issuer;

          (e) any invalidity of, or defect or deficiency in the Preferred
Securities;

          (f) the settlement or compromise of any obligation guaranteed hereby
or hereby incurred; or

                                       12
<PAGE>

          (g) any other circumstance whatsoever that might otherwise constitute
a legal or equitable discharge or defense of a guarantor, it being the intent of
this Section 5.04 that the obligations of the Guarantor hereunder shall be
absolute and unconditional under any and all circumstances.

     There shall be no obligation of the Holders or any other Person to give
notice to, or obtain consent of, the Guarantor with respect to the happening of
any of the foregoing.

SECTION 5.05  Rights of Holders.

     The Guarantor expressly acknowledges that:

          (a) This Guarantee will be deposited with the Guarantee Trustee to be
held for the benefit of the Holders.

          (b) The Guarantee Trustee has the right to enforce this Guarantee on
behalf of the Holders.

          (c) The Holders of a Majority in liquidation amount of the Preferred
Securities have the right to direct the time, method and place of conducting any
proceeding for any remedy available to the Guarantee Trustee in respect of this
Guarantee or exercising any trust or power conferred upon the Guarantee Trustee
under this Guarantee.

          (d) Any Holder may institute a legal proceeding directly against the
Guarantor to enforce its rights under this Guarantee, without first instituting
a legal proceeding against the Issuer, the Guarantee Trustee or any other
Person.

SECTION 5.06  Guarantee of Payment.

     This Guarantee creates a guarantee of payment and not of collection. This
Guarantee will not be discharged except by payment of the Guarantee Payments in
full (without duplication of amounts theretofore paid by the Issuer) or upon
distribution of Debentures to Holders as provided in the Declaration.

SECTION 5.07  Subrogation.

     The Guarantor shall be subrogated to all (if any) rights of the Holders
against the Issuer in respect of any amounts paid to such Holders by the
Guarantor under this Guarantee and shall have the right to waive payment by the
Issuer pursuant to Section 5.01; provided, however, that the Guarantor shall not
(except to the extent required by mandatory provisions of law) be entitled to
enforce or exercise any right that it may acquire by way of subrogation or any
indemnity, reimbursement or other agreement, in all cases as a result of payment
under this Guarantee, if, at the time of any such payment, any amounts are due
and unpaid under this Guarantee. If any amount shall be paid to the Guarantor in
violation of the preceding sentence, the Guarantor agrees to hold such amount in
trust for the Holders and to pay over such amount to the Holders.

                                       13

SECTION 5.08  Independent Obligations.

     The Guarantor acknowledges that its obligations hereunder are independent
of the obligations of the Issuer with respect to the Preferred Securities, and
that the Guarantor shall be liable as principal and as debtor hereunder to make
Guarantee Payments pursuant to the terms of this Guarantee notwithstanding the
occurrence of any event referred to in subsections (a) through (g), inclusive,
of Section 5.04 hereof.

SECTION 5.09  Conversion.

     The Guarantor acknowledges its obligation to issue and deliver common stock
upon the conversion of the Preferred Securities.

                   Limitation of Transactions; Subordination

SECTION 6.01  Limitation of Transactions.

     So long as any Preferred Securities remain outstanding, if there shall have
occurred and be continuing a Debenture Event of Default, a Declaration Event of
Default or an event that, with the giving of notice or the lapse of time or
both, would constitute a Debenture Event of Default or a Declaration Event of
Default, or a selection by the Guarantor of a Deferral Period as provided in the
Indenture and such period, or any extension thereof, shall be continuing, then
(a) the Guarantor shall not declare or pay any dividend on, or make any
distribution with respect to, or redeem, purchase, acquire or make a liquidation
payment with respect to, any of its capital stock (other than stock dividends
paid by the Guarantor which stock dividends consist of the stock of the same
class as that on which the dividend is being paid), (b) the Guarantor shall not
make any payment of interest, principal or premium, if any, on or repay,
repurchase or redeem any debt securities issued by the Guarantor which rank pari
passu with or junior in interest to the Debentures and (c) the Guarantor shall
not make any guarantee payments with respect to any guarantee by the Guarantor
of the debt securities of any subsidiary of the Guarantor if such guarantee
ranks pari passu with or junior in interest to the Debentures (in each case,
other than (A) dividends or distributions in Common Stock, (B) any declaration
of a dividend in connection with the implementation of a stockholders' rights
plan, or the issuance of stock under any such plan in the future, or the
redemption or repurchase of any such rights pursuant thereto, (C) payments under
this Guarantee and the Common Securities Guarantee, (D) purchases or
acquisitions of shares of Common Stock in connection with the satisfaction by
the Guarantor of its obligations under any employee benefit plan or any other
contractual obligation of the Guarantor (other than a contractual obligation
ranking pari passu with or junior in interest to the Debentures), (E) as a
result of a reclassification of the Guarantor's capital stock or the exchange or
conversion of one class or series of the Guarantor's capital stock for another
class or series of the Guarantor's capital stock or (F) the purchase of
fractional interests in shares of the Guarantor's capital stock pursuant to the
conversion or exchange provisions of such capital stock or the security being
converted or exchanged).

SECTION 6.02  Ranking.

     This Guarantee will constitute an unsecured obligation of the Guarantor and
will rank subordinate to all Senior Debt of the Guarantor to the same extent
that the Debentures are subordinated pursuant to the Indenture.

                                  ARTICLE VII

                                  Termination

SECTION 7.01  Termination.

     This Guarantee shall terminate upon (i) full payment of the amount payable
upon redemption of all Preferred Securities, (ii) the distribution of the
Guarantor's common stock to the Holders in respect of the conversion of the
Preferred Securities into the Guarantor's common stock, (iii) the distribution
of the Debentures to the Holders of all of the Preferred Securities or (iv) full
payment of the amounts payable in accordance with the Declaration upon
liquidation of the Issuer. Notwithstanding the foregoing, this Guarantee will
continue to be effective or will be reinstated, as the case may be, if at any
time any Holder must restore payment of any sums paid under the Preferred
Securities or under this Guarantee.

                                 ARTICLE VIII

                                Indemnification

SECTION 8.01  Exculpation.

in damages or otherwise to the Guarantor or any Covered Person for any loss,
damage or claim incurred by reason of any act or omission performed or omitted
by such Indemnified Person in good faith in accordance with this Guarantee and
in a manner that such Indemnified Person reasonably believed to be within the
scope of the authority conferred on such Indemnified Person by this Guarantee or
by law, except that an Indemnified Person shall be liable for any such loss,
damage or claim incurred by reason of such Indemnified Person's negligence or
willful misconduct with respect to such acts or omissions.

          (b) An Indemnified Person shall be fully protected in relying in good
faith upon the records of the Guarantor and upon such information, opinions,
reports or statements presented to the Guarantor by any Person as to matters the
Indemnified Person reasonably believes are within such other Person's
professional or expert competence and who has been selected with reasonable care
by or on behalf of the Guarantor, including information, opinions, reports or
statements as to the value and amount of the assets, liabilities, profits,
losses, or any other facts pertinent to the existence and amount of assets from

to hold each Indemnified Person harmless against, any and all loss, liability or
expense including taxes (other than taxes based on the income of such
Indemnified Person) incurred without negligence or bad faith on its part,
arising out of or in connection with the acceptance or administration of the
trust or trusts hereunder, including the costs and expenses (including
reasonable legal fees and expenses) of defending itself against or investigating
any claim or liability in connection with the exercise or performance of any of
its powers or duties hereunder. The obligation to indemnify as set forth in this
Section 8.02 shall survive the termination of this Guarantee.

          (b) To the fullest extent permitted by applicable law, expenses
(including legal fees and expenses) incurred by an Indemnified Person in
defending any claim, demand, action, suit or proceeding shall, from time to
time, be advanced by the Guarantor prior to the final disposition of such claim,
demand, action, suit or proceeding upon receipt by the Guarantor of an
undertaking by or on behalf of the Indemnified Person to repay such amount if it
shall be determined that the Indemnified Person is not entitled to be
indemnified as authorized in Section 8.02(a).

          (c) No Indemnified Person shall claim or exact any lien or charge on
any Guarantee Payments as a result of any amount due to it under this Guarantee.

any of the foregoing.

SECTION 2.05  Rights of Holders.

     The Guarantor expressly acknowledges that any Holder may institute a legal
proceeding directly against the Guarantor to enforce its rights under this
Common Securities Guarantee, without first instituting a legal proceeding

the Guarantor shall be liable as principal and as debtor hereunder to make
Guarantee Payments pursuant to the terms of this Common Securities Guarantee
notwithstanding the occurrence of any event referred to in subsections (a)
through (g), inclusive, of Section 2.04 hereof.

SECTION 2.09  Conversion.

     The Guarantor acknowledges its obligation to issue and deliver common stock
upon the conversion of the Common Securities.

SECTION 2.10  Events of Default; Waiver.

     The Holders of a majority in liquidation amount of Common Securities may by
vote, on behalf of the Holders of all of the Common securities, waive any past
Guarantee Event of Default and its consequences.  Upon such waiver, any such
Guarantee Event of Default shall cease to exist, and any Guarantee Event of
Default arising therefrom shall be deemed to have been cured, for every purpose
of this Common Securities Guarantee, but no such waiver shall extend to any
subsequent or other default or Guarantee Event of Default or impair any right
consequent thereon.

time or both, would constitute a Debenture Event of Default or a Declaration
Event of Default or (ii) a selection by the Guarantor of a Deferral Period as

liquidation payment with respect to, any of its capital stock (other than stock
dividends paid by the Guarantor which consist of the stock of the same class as
that on which the dividend is being paid), (b) the Guarantor shall not make any
payment of interest, principal or premium, if any, on or repay, repurchase or

payments with respect to any guarantee by the Guarantor of the debt securities
of any

                                       6

under any such plan in the future, or the redemption or repurchase of any such

the Guarantor and will rank subordinate to all Senior Debt of the Guarantor to
the same extent that the Debentures (as defined in the Indenture) are
subordinated pursuant to the Indenture.

                                  ARTICLE IV

Securities Guarantee.
