By: ----------------------------------- Authorized Signatory Date: August 30, 2001 8.50% Senior Secured Note due 2008 1. Interest Hanover Equipment Trust 2001A, a Delaware business trust (such business trust, and its successors and assigns under the Indenture hereinafter referred to, being herein called the "Issuer"), promises to pay interest on the principal amount of this Security at the rate per annum shown above. The Issuer will pay interest semiannually in arrears on March 1 and September 1 of each year commencing March 1, 2002. Interest on the Securities will accrue from the most recent date to which interest has been paid on the Securities or, if no interest has been paid, from September 1, 2001. The Issuer shall pay interest on overdue principal or premium, if any (plus interest on such interest to the extent lawful), at the rate borne by the Securities to the extent lawful. Interest will be computed on the basis of a 360-day year of twelve 30-day months. 2. Method of Payment By at least 10:00 a.m. (New York City time) on the date on which any principal of or interest on any Security is due and payable, the Issuer shall irrevocably deposit with the Trustee or the Paying Agent money sufficient to pay such principal, premium, if any, and/or interest.

The Issuer will pay principal and interest in money of the United States that at the time of payment is legal tender for payment of public and private debts. Payments in respect of Securities represented by a Global Security (including principal, premium, if any, and interest) will be made by the transfer of immediately available funds to the accounts specified by The Depository Trust Company. The Issuer will make all payments in respect of a Definitive Security (including principal, premium, if any, and interest) by mailing a check to the registered address of each Holder thereof; provided, however, that payments on the Securities may also be made, in the case of a Holder of a least $1,000,000 aggregate principal amount of Securities, by wire transfer to a U.S. dollar account maintained by the payee with a bank in the United States if such Holder elects payment by wire transfer by giving written notice to the Trustee or the Paying Agent to such effect designating such account no later than 15 days immediately preceding the relevant due date for payment (or such other date as the Trustee may accept in its discretion). 3.

The Issuer may appoint and change any Paying Agent, Registrar or co-registrar without notice to any Securityholder. The Issuer or any of its Restricted Subsidiaries may act as Paying Agent, Registrar or co-registrar. 5 4. Indenture The Issuer issued the Securities under an Indenture dated as of August 30,2001 (as it may be amended or supplemented from time to time in accordance with the terms thereof, the "Indenture"), among the Issuer, the Hanover Guarantors and the Trustee, and a Participation Agreement dated as of August 30, 2001 (the "Participation Agreement") among the Issuer, the Lessee, the Certificate Holders named therein, the Hanover Guarantors, the Trustee and Wilmington Trust Company. The terms of the Securities include those stated in the Indenture and the Participation Agreement and those made part of the Indenture by reference to the Trust Indenture Act of 1939 (15 U.S.C. Sections 77aaa-77bbbb) as in effect on the date of the Indenture (the "Act"). Capitalized terms used herein and not defined herein have the meanings ascribed thereto in the Indenture. The Securities are subject to all such terms, and Securityholders are referred to the Indenture and the Act for a statement of those terms. The Securities are secured senior obligations of the Issuer limited to $300 million aggregate principal amount (subject to Section 2.2 of the Indenture). This Security is one of the Original Securities (also referred to as Initial Securities) referred to in the Indenture. The Initial Securities and the Exchange Securities will be treated as a single class of securities under the Indenture. The Indenture and the Participation Agreement impose certain limitations on, among other things: the Incurrence of Indebtedness by the Issuer or Hanover or its Restricted Subsidiaries, the purchase or redemption of Capital Stock of Hanover, the Incurrence of Liens by the Issuer or Hanover or its Restricted Subsidiaries, the sale of transfer of assets and Capital Stock of Restricted Subsidiaries of Hanover, the issuance or sale of Capital Stock of Restricted Subsidiaries of Hanover, the business activities and investments of the Issuer, mergers and consolidation of Hanover, and transactions with Affiliates of Hanover and its Restricted Subsidiaries. In addition, the Participation Agreement limits the ability of Hanover and its Restricted Subsidiaries to restrict distributions and dividends from Restricted Subsidiaries. To guarantee the due and punctual payment of the principal, premium, if any, and interest on the Securities and all other amounts payable by the Issuer under the Indenture and the Securities when and as the same shall be due and payable, whether at maturity, by acceleration or otherwise, according to the terms of the Securities and the Indenture, the Hanover Guarantors will have unconditionally guaranteed, upon the release of escrowed funds pursuant to an Escrow Agreement, dated as of August 30, 2001 (the "Escrow Agreement"), among the Issuer, Hanover Equipment Trust 2001B and Wilmington Trust Company, as escrow agent, (and future Hanover Guarantors, together with the Hanover Guarantors, will unconditionally guarantee) jointly and severally, upon the occurrence of and during a Lease Event of Default, such obligations on a senior subordinated basis pursuant to the terms of a Guarantee, to be dated as of the date the escrowed funds are released pursuant to the Escrow Agreement, by the Hanover Guarantors. 5. Redemption Except as set forth below, the Securities will not be redeemable at the option of the Issuer prior to September 1, 2005. On and after such date, the Issuer may redeem all or, from time to time, a part of the Securities upon not less than 30 nor more than 60 days' prior notice mailed by first-class mail to each Holder's registered address and in accordance with the provisions of Section 20.1 of the Lease, at the following redemption prices (expressed in 6 percentages of principal amount), plus accrued and unpaid interest, if any, to the redemption date subject to the right of Holders of record on the relevant record date to receive interest due on the relevant interest payment date), if redeemed during the 12-month period commencing on September 1 of the years set forth below: Redemption Period Price - ------ ----- 2005 104.250% 2006 102.125% 2007 and thereafter 100.000% Prior to September 1, 2004, to the extent that Hanover raises Net Cash Proceeds from one or more Public Equity Offerings and such Net Cash Proceeds are contributed toward an Equipment Purchase (as defined below), the Issuer may on any one or more occasions redeem up 1 to 35% of the original principal amount of the Securities with the proceeds from an Equipment 1 Purchase in accordance with the provisions of Section 20.l(b) of the Lease at a redemption price 1 (expressed as a percentage of principal amount) of 108.50% plus accrued and unpaid interest, if I any, to the redemption date (subject to the right of Holders of record on the relevant record date to receive interest due on the relevant interest payment date); provided, however, that at-least 65% of the original principal amount of the Securities must remain outstanding after each such redemption; provided further, that each such redemption occurs within 60 days of the date of closing of such Public Equity Offering. In each case, the Issuer will redeem the Securities with the proceeds from the Lessee's purchase of the Issuer's Equipment (the "Equipment Purchase"), in accordance with Sections 20.1 (a) or 20.1(b), as applicable, of the Lease. In the case of any partial redemption, selection of the Securities for redemption will be made by the Trustee in compliance with the requirements of the principal national securities exchange, if any, on which the Securities are listed or, if the Securities are not listed, then on a pro rata basis, by lot or by such other method as the Trustee in its sole discretion shall deem to be fair and appropriate, although no Securities of $1,000 in original principal amount or less will be redeemed in part. If any Security is to be redeemed in part only, the notice of redemption relating to such Security shall state the portion of the principal amount thereof to be redeemed. A new Security in principal amount equal to the unredeemed portion thereof will be issued in the name of the Holder thereof upon cancellation of the original Security. On and after the redemption date, interest will cease to accrue on Securities or portions thereof called for redemption as long as the Issuer has deposited with the Paying Agent funds in satisfaction of the applicable redemption price pursuant to the Indenture. If, in the sole judgment of the trustee of the Issuer prior to the POI Acquisition (defined below), the acquisition by the Lessee and its affiliates of Production Operators Corporation and certain other assets of Schlumberger Limited ("Schlumberger") and its affiliates, pursuant to that certain Purchase Agreement dated as of June 28, 2001 by and among Hanover Compression Limited Partnership, Schlumberger and the other parties named therein (the "POI Acquisition"), will not be consummated by November 15, 2001, the Issuer may at its option at any time before November 1, 2001 redeem all, but not less than all, of the Securities 7 then Outstanding at a redemption price (expressed as a percentage of principal amount) of 101%, plus accrued and unpaid interest to the redemption date ("Special Optional Redemption"). In the event that there has been no Special Optional Redemption and the POI Acquisition has not been consummated by November 15, 2001, on November 30, 2001 the Issuer shall redeem all Securities then Outstanding at a redemption price (expressed as a percentage of principal amount) of 101%, plus accrued and unpaid interest to the redemption date ("Special Mandatory Redemption", and together with Special Option Redemption, "Special Redemption"). If a redemption date is on or after an interest record date and on or before the related interest payment date, the accrued and unpaid interest, if any, will be paid to the Person in whose name the Security is registered at the close of business on such record date, and no additional interest will be payable to Holders whose Securities will be subject to redemption by the Issuer. 6. Repurchase Provisions (a) Upon a Change of Control with respect to Hanover, any Holder of Securities will have the right to cause the Issuer to repurchase all or any part of the Securities of such Holder at a purchase price in cash equal to 101% of the principal amount thereof, plus accrued and unpaid interest, if any, to the date of repurchase (subject to the right of Holders of record on the relevant record date to receive interest due on the relevant interest payment date) as provided in, and subject to the terms of, the Indenture. The Issuer will repurchase the Securities with the proceeds from an Equipment Purchase in accordance with Section: 20.l(c) of the Lease. (b) In the event of an Asset Disposition that requires the purchase of Securities pursuant to Section 9.6 of the Participation Agreement and Section 3.3 of the Indenture, the Issuer will be required to apply such Excess Proceeds to the repayment of the Securities in accordance with the procedures set forth in Section 3.3 of the Indenture.

The Registrar may require a Holder, among other things, to finish appropriate endorsements or transfer documents and to pay any taxes and fees required by law or permitted by the Indenture. The Registrar need not register the transfer of or exchange (i) any Securities selected for redemption (except, in the case of a Security to be redeemed in part, the portion of the Security not to be redeemed) for a period beginning 15 days before the mailing of a notice of Securities to be redeemed and ending on the date of such mailing or (ii) any Securities for a period beginning 15 days before an interest payment date and ending on such interest payment date. 8 8. Persons Deemed Owners The registered Holder of this Security may be treated as the owner of it for all purpose. 9. Unclaimed Money If money for the payment of principal or interest remains unclaimed for two years, the Trustee or Paying Agent shall pay the money back to the Issuer at its request unless an abandoned property law designates another Person. After any such payment, Holders entitled to the money must look only to the Issuer and not to the Trustee for payment. 10. Defeasance Subject to certain conditions set forth in the Indenture, the Issuer at any time may terminate some or all of its obligations under the Securities and the Indenture if the Issuer deposits with the Trustee money or U.S. Government Obligations for the payment of principal and interest on the Securities to redemption or maturity, as the case may be. 11.

However, a default under clauses (iv) and (v) will not constitute an Event of Default until the Trustee or the Holders of at least 25% in principal amount of the outstanding Securities notify the Issuer of the default and the Issuer does not cure such default within the time specified in clauses (iv) and (v) hereof after receipt of such notice. If an Event of Default (other than an Event of Default described in clause (ix) above) occurs and is continuing, the Trustee or the Holders of at least 25% in principal amount of the Securities may declare all the Securities to be due and payable immediately. Events of Default described in clause (ix) above will result in the Securities being due and payable immediately upon the occurrence of such Events of Default. Securityholders may not enforce the Indenture or the Securities except as provided in the Indenture. The Trustee may refuse to enforce the Indenture or the Securities unless it receives reasonable indemnity or security. Subject to certain limitations, Holders of a majority in principal amount of the Securities may direct the Trustee in its exercise of any trust 10 or power. The Trustee may withhold from Securityholders notice of any continuing Default or Event of Default (except a Default or Event of Default in payment of principal or interest) if it determines that withholding notice is in their interest. 13. Trustee Dealings with the Issuer Subject to certain limitations set forth in the Indenture, the Trustee under the Indenture, in its individual or any other capacity, may become the owner or pledgee of Securities and may otherwise deal with and collect obligations owed to it by the Issuer or its Affiliates and may otherwise deal with the Issuer or its affiliates with the same rights it would have if it were not Trustee. 14.
