        Re: Hanover Equipment Trust 2001A / 8.50% Senior Secured Notes due 2008
            -------------------------------------------------------------------

Ladies and Gentlemen:

        Hanover Equipment Trust 2001A, a Delaware business trust (the "Issuer"),
proposes to make an offer (the "Exchange Offer") to exchange an aggregate
principal amount of up to $300,000,000 of its outstanding 8.50% Senior Secured
Notes due 2008 (the "Old Notes"), for a like principal amount of the Issuer's
8.50% Senior Secured Notes due 2008, which have been registered under the
Securities Act of 1933, as amended (the "New Notes"). The New Notes are
guaranteed by Hanover Compressor Company, a Delaware corporation ("Hanover"),
and Hanover Compression Limited Partnership, a Delaware limited partnership
("HCLP"; we refer to HCLP and Hanover collectively as the "Guarantors"). The
terms and conditions of the Exchange Offer as currently contemplated are set
forth in a prospectus dated ___________, 2002 (the "Prospectus"), proposed to be
distributed to all record holders of the Old Notes as of __________, 2002. The
Old Notes and the New Notes are collectively referred to herein as the "Notes."

        The Issuer hereby appoints Wilmington Trust FSB to act as exchange agent
(the "Exchange Agent") in connection with the Exchange Offer. References
hereinafter to "you" shall refer to Wilmington Trust FSB.

        The Exchange Offer is expected to be commenced by the Issuer on or about
__________, 2002. The Letter of Transmittal accompanying the Prospectus or, in
the case of book-entry securities, the Automated Tender Offer Program of The
Depository Trust Company (the "Book-Entry Transfer Facility"), are to be used by
the holders of the Old Notes to accept the Exchange Offer, and the Letter of
Transmittal contains instructions with respect to the delivery of certificates
for Old Notes tendered.

        The Exchange Offer shall expire at 5:00 P.M., New York City time, on
_________, 2002 or on such later date or time to which the Issuer may extend the
Exchange



Offer (the "Expiration Date"). Subject to the terms and conditions set forth in
the Prospectus, the Issuer expressly reserves the right to extend the Exchange
Offer from time to time and may extend the Exchange Offer by giving oral
(promptly confirmed in writing) or written notice to you before 9:00 A.M., New
York City time, on the business day following the previously scheduled
Expiration Date.

             The Issuer expressly reserves the right to amend or terminate the
Exchange Offer, and not to accept for exchange any Old Notes not theretofore
accepted for exchange. The Issuer will give oral (promptly confirmed in writing)
or written notice of any amendment, termination or nonacceptance to you as
promptly as practicable.

             In carrying out your duties as Exchange Agent, you are to act in
accordance with the following instructions:

             1. You will perform such duties and only such duties as are
specifically set forth in the section of the Prospectus entitled "The Exchange
Offer" and as specifically set forth herein and such duties which are
necessarily incidental thereto; provided, however, that in no way will your
                                --------  -------
general duty to act in good faith and without gross negligence or willful
misconduct be limited by the foregoing.

             2. You will establish an account with respect to the Old Notes at
the Book-Entry Transfer Facility for purposes of the Exchange Offer within two
business days after the date of the Prospectus, or, if you already have
established an account with the Book-Entry Transfer Facility suitable for the
Exchange Offer, you will identify such pre-existing account to be used in the
Exchange Offer, and any financial institution that is a participant in the
Book-Entry Transfer Facility's systems may make book-entry delivery of the Old
Notes by causing the Book-Entry Transfer Facility to transfer such Old Notes
into your account in accordance with the Book-Entry Transfer Facility's
procedure for such transfer.

             3. You are to examine each of the Letters of Transmittal and
certificates for Old Notes and each confirmation of book-entry transfer into
your account at the Book-Entry Transfer Facility and any other documents
delivered or mailed to you by or for holders of the Old Notes to ascertain
whether: (i) the Letters of Transmittal and any such other documents are duly
executed and properly completed in accordance with instructions set forth
therein and that such book-entry confirmations are in due and proper form and
contain the information required to be set forth therein and (ii) the Old Notes
have otherwise been properly tendered. In each case where the Letter of
Transmittal or any other document has been improperly completed or executed or
where such book-entry confirmations are not in due and proper form or omit
certain information, or where any of the certificates for Old Notes are not in
proper form for transfer or some other irregularity in connection with the
acceptance of the Exchange Offer exists, you will use commercially reasonable
and customary efforts to inform the presenters of the need (i) for fulfillment
of all requirements and (ii) to take any other action as may be necessary or
advisable to cause such irregularity to be corrected.

             4. With the approval of the President and Chief Executive Officer,
the Executive Vice President, any Vice President or the Secretary of Hanover
(such approval, if given orally, to be promptly confirmed in writing) or any
other party designated by such officer

                                        2



in writing, you are authorized to waive any defects, irregularities or
conditions of tender in connection with any tender of Old Notes pursuant to the
Exchange Offer.

             5. At the written request and expense of the Issuer, you shall
notify tendering holders of Old Notes (through the facilities of the Book-Entry
Transfer Facility in the case of book-entry securities) in the event of any
extension, termination or amendment of the Exchange Offer. In the event of any
such termination, you will return all tendered Old Notes to the persons entitled
thereto, at the request and expense of the Issuer.

             6. Tenders of Old Notes may be made only as set forth in the Letter
of Transmittal and in the section of the Prospectus captioned "The Exchange
Offer--Procedures for Tendering," and Old Notes shall be considered properly
tendered to you only when tendered in accordance with the procedures set forth
therein. Notwithstanding the provisions of this paragraph 6, Old Notes which the
President and Chief Executive Officer, the Executive Vice President, any Vice
President or the Secretary of Hanover or any other party designated by such
officer in writing shall approve as having been properly tendered shall be
considered to be properly tendered (such approval, if given orally, shall be
promptly confirmed in writing).

             7. You shall advise the Issuer and the Guarantors with respect to
any Old Notes delivered subsequent to the Expiration Date and accept their
instructions with respect to disposition of such Old Notes.

             8. You shall accept tenders:

                (a) in cases where the Old Notes are registered in two or more
             names only if signed by all named holders;

                (b) in cases where the signing person (as indicated on the
             Letter of Transmittal) is acting in a fiduciary or a representative
             capacity only when proper evidence of his or her authority so to
             act is submitted; and

                (c) from persons other than the registered holder of Old Notes
             provided that customary transfer requirements, including any
             applicable transfer taxes, are fulfilled.

             9. You shall accept partial tenders of Old Notes where so indicated
and as permitted in the Letter of Transmittal and deliver certificates for Old
Notes to the transfer agent therefor for split-up and return any untendered Old
Notes to the holder (or such other person as may be designated in the Letter of
Transmittal) as promptly as practicable after expiration or termination of the
Exchange Offer.

             10. Upon satisfaction or waiver of all of the conditions to the
Exchange Offer, the Issuer will notify you (such notice, if given orally, to be
promptly confirmed in writing) of the acceptance, promptly after the Expiration
Date, of all Old Notes properly tendered and you, on behalf of the Issuer, will
exchange such Old Notes for New Notes and cause such Old Notes to be canceled.
Delivery of New Notes will be made on behalf of the Issuer by you at the rate of
$1,000 principal amount of New Notes for each $1,000 principal amount of Old
Notes tendered promptly after notice (such notice, if given orally, to be
promptly confirmed in writing) of

                                        3



acceptance of such Old Notes by the Issuer; provided, however, that in all
                                            --------  -------
cases, Old Notes tendered pursuant to the Exchange Offer will be exchanged only
after timely receipt by you of certificates for such Old Notes (or confirmation
of book-entry transfer into your account at the Book-Entry Transfer Facility), a
properly completed and duly executed Letter of Transmittal (or facsimile thereof
or an agent's message in lieu thereof) with any required signature guarantees
and any other required document. You shall issue New Notes only in denominations
of $1,000 or any integral multiple thereof.

             11. Tenders pursuant to the Exchange Offer are irrevocable, except
that, subject to the terms and upon the conditions set forth in the Prospectus
and the Letter of Transmittal, Old Notes tendered pursuant to the Exchange Offer
may be withdrawn at any time prior to the Expiration Date.

             12. The Issuer shall not be required to exchange any Old Notes
tendered if any of the conditions set forth in the Exchange Offer are not met.
Notice of any decision by the Issuer not to exchange any Old Notes tendered
shall be given (such notice, if given orally, shall be promptly confirmed in
writing) by the Issuer to you.

             13. If, pursuant to the Exchange Offer, the Issuer does not accept
for exchange all or part of the Old Notes tendered because of an invalid tender,
the occurrence of certain other events set forth in the Prospectus under the
caption "The Exchange Offer--Conditions to the Exchange Offer" or otherwise, you
shall as soon as practicable after the expiration or termination of the Exchange
Offer return those certificates for unaccepted Old Notes (or effect appropriate
book-entry transfer), together with any related required documents and the
Letters of Transmittal relating thereto that are in your possession, to the
persons who deposited them.

             14. All certificates for reissued Old Notes, unaccepted Old Notes
or for New Notes shall be forwarded by (a) first-class mail, postage prepaid
under a blanket surety bond protecting you and the Issuer from loss or liability
arising out of the nonreceipt or nondelivery of such certificates or (b) by
registered mail insured separately for the replacement value of each of such
certificates.

             15. You are not authorized to pay or offer to pay any concessions,
commissions or solicitation fees to any broker, dealer, bank, trust company or
other persons or to engage or utilize any person to solicit tenders.

             16. As Exchange Agent hereunder you:

                (a) will be regarded as making no representations and having no
             responsibilities as to the validity, sufficiency, value or
             genuineness of any of the certificates or the Old Notes represented
             thereby deposited with you pursuant to the Exchange Offer, and will
             not be required to and will make no representation as to the
             validity, value or genuineness of the Exchange Offer; provided,
                                                                   --------
             however, that in no way will your general duty to act in good faith
             -------
             and without gross negligence or willful misconduct be limited by
             the foregoing;

                                        4



                    (b) shall not be obligated to take any action hereunder
             which might in your reasonable judgment involve any expense or
             liability, unless you shall have been furnished with reasonable
             indemnity therefore;

                    (c) shall not be liable to the Issuer or the Guarantors for
             any action taken or omitted by you, or any action suffered by you
             to be taken or omitted, without gross negligence, willful
             misconduct or bad faith on your part, by reason of or as a result
             of the administration of your duties hereunder in accordance with
             the terms and conditions of this Agreement or by reason of your
             compliance with the instructions set forth herein or with any
             written or oral instructions delivered to you pursuant hereto, and
             may rely on and shall be protected in acting in good faith in
             reliance upon any certificate, instrument, opinion, notice, letter,
             facsimile or other document or security delivered to you and

             the proper party or parties;

                    (d) may act upon any tender, statement, request, comment,
             agreement or other instrument whatsoever not only as to its due
             execution and validity and effectiveness of its provisions, but
             also as to the truth and accuracy of any information contained
             therein, which you in good faith reasonably believe to be genuine
             or to have been signed or represented by a proper person or
             persons;

                    (e) may rely on and shall be protected in acting upon
             written or oral instructions from the President and Chief Executive
             Officer, the Executive Vice President, any Vice President or the

             behalf of Hanover or as attorneys-in-fact and agents of the Issuer
             or HCLP, with respect to the Exchange Offer;

                    (f) shall not advise any person tendering Old Notes pursuant
             to the Exchange Offer as to the wisdom of making such tender or as
             to the market value or decline or appreciation in market value of
             any Old Notes; provided, however, that in no way will your general
                            --------  -------
             duty to act in good faith and without gross negligence or willful
             misconduct be limited by the foregoing;

             and protection in respect of any action taken, suffered or omitted
             by you hereunder in good faith and in accordance with such written
             opinion of such counsel; and

                    (h) in no event will you be liable for special, indirect or
             consequential loss or damage of any kind whatsoever (including but
             not limited to lost profits) arising in connection with this
             Agreement.

             17. You shall take such action as may from time to time be
requested by the Issuer, the Guarantors or their outside counsel (and such other
action as you may reasonably deem necessary) to furnish copies of the
Prospectus, the Letter of Transmittal and the Notice of Guaranteed Delivery, or

          --------  -------
additional Old Notes have been tendered, no additional items have been received
by you and such totals have not changed since you last provided such information
as required above, you need not provide the information referred to above in
this paragraph 18 on such day. In addition, you will also confirm, and cooperate
in making available, to the Issuer and the Guarantors or any such other person
or persons as the Issuer or the Guarantors request from time to time prior to

requests. Such cooperation shall include, without limitation, the granting by

accepted, the aggregate principal amount of Old Notes tendered and the aggregate
principal amount of Old Notes accepted and deliver said list to the Issuer and
the Guarantors.

                19. Letters of Transmittal and Notices of Guaranteed Delivery
shall be stamped by you as to the date and the time of receipt and shall, except
as provided in paragraph 13, be preserved by you for a period of time at least
equal to the period of time you preserve other records pertaining to the
transfer of securities (or, if earlier, until such time as such documents are
delivered to the Issuer upon termination of this Agreement, pursuant to
paragraph 31).

                20. You hereby expressly waive any lien, encumbrance or right
of set-off whatsoever that you may have with respect to funds deposited with you
for the payment of transfer taxes by reason of amounts, if any, borrowed by the
Issuer or the Guarantors, or any of their subsidiaries or affiliates pursuant to
any loan or credit agreement with you or for compensation owed to you hereunder.

                21. For services rendered as Exchange Agent hereunder, you
shall be entitled to compensation of $_____ and you shall be entitled to
reimbursement of your reasonable out-of-pocket expenses (including reasonable
attorneys' fees and expenses of your counsel) incurred in connection with your
services hereunder or under any other agreement.


                                       6

of Transmittal and the other documents associated with the Exchange Offer
attached hereto and further acknowledge that you have examined each of them to
the extent necessary to perform your duties hereunder. Any inconsistency between
this Agreement, on the one hand, and the Prospectus and the Letter of
Transmittal (as they may be amended from time to time), on the other hand, shall
be resolved in favor of the latter two documents, except with respect to the
duties, liabilities and indemnification of you as Exchange Agent, which shall be
controlled by this Agreement.

               23. The Issuer and each Guarantor agrees, jointly and severally,
to indemnify and hold harmless you, in your capacity as Exchange Agent
hereunder, against any liability, cost or expense, including reasonable
attorneys' fees, incurred without gross negligence or willful misconduct on your
part, arising out of or in connection with any act, omission, delay or refusal
made by you in reliance upon any signature, endorsement, assignment,
certificate, order, request, notice, instruction or other instrument or document
believed by you in good faith to be valid and genuine and in accepting any
tender or effecting any transfer of Old Notes believed by you in good faith to
be authorized, and in delaying or refusing in good faith to accept any tenders
or effect any transfer of Old Notes or otherwise arising out of or in connection
with your acting as Exchange Agent hereunder; provided, however, that the none
                                              --------  -------
of the Issuer or the Guarantors shall be liable for indemnification or otherwise
for any loss, liability, cost or expense to the extent arising out of your gross
negligence, willful misconduct or bad faith. In no case shall the Issuer or the
Guarantors be liable under this indemnity with respect to any claim against you
unless the Issuer and the Guarantors shall be notified by you, by letter or
cable or by facsimile confirmed by letter, of the assertion of a claim against
you or of any other action commenced against you, promptly after you shall have
received any such assertion or notice of the commencement of any such action.

expense in the defense of any such claim or other action, and, if the Issuer or
the Guarantors so elect, it or they may assume the defense of any suit brought
to enforce any such claim. In the event that any of the Issuer or the Guarantors
assume the defense of any such suit, none of the Issuer or the Guarantors shall
be liable for the fees and expenses of any additional counsel thereafter
retained by you so long as it or they retain counsel reasonably satisfactory to
you to defend such suit.

               24. You shall arrange to comply with all requirements under the
tax laws of the United States, including those relating to missing Tax
Identification Numbers, and shall file any appropriate reports with the Internal
Revenue Service.

manner to each governmental authority to which any transfer taxes are payable in
respect of the exchange of Old Notes, your check in the amount of all transfer
taxes so payable, and the Issuer shall reimburse you for the amount of any and
all transfer taxes payable in respect of the exchange of Old Notes; provided,

the Issuer for amounts refunded to you in respect of your payment of any such
transfer taxes, at such time as such refund is received by you.

               26. This Agreement and your appointment as Exchange Agent
hereunder shall be construed and enforced in accordance with the laws of the
State of New York applicable to


                                       7
