                        Report of Independent Accountants

To the Participants and Plan Administrator of
The Hanover Companies Retirement Savings Plan

In our opinion, the accompanying statement of net assets available for benefits
and the related statement of changes in net assets available for benefits
present fairly, in all material respects, the net assets available for benefits
of The Hanover Companies Retirement Savings Plan (the Plan) at December 31, 2001
and 2000, and the changes in net assets available for benefits for the year
ended December 31, 2001 in conformity with accounting principles generally
accepted in the United States of America. These financial statements are the
responsibility of the Plan's management; our responsibility is to express an
opinion on these financial statements based on our audits. We conducted our
audits of these statements in accordance with auditing standards generally
accepted in the United States of America, which require that we plan and perform
the audit to obtain reasonable assurance about whether the financial statements
are free of material misstatement. An audit includes examining, on a test basis,
evidence supporting the amounts and disclosures in the financial statements,
assessing the accounting principles used and significant estimates made by
management, and evaluating the overall financial statement presentation. We
believe that our audits provide a reasonable basis for our opinion.

Our audits were conducted for the purpose of forming an opinion on the basic
financial statements taken as a whole. The Supplemental Schedule of Assets (Held
at End of Year) is presented for the purpose of additional analysis and is not a
required part of the basic financial statements but is supplementary information
required by the Department of Labor's Rules and Regulations for Reporting and
Disclosure under the Employee Retirement Income Security Act of 1974. The
supplemental schedule is the responsibility of the Plan's management. The
supplemental schedule has been subjected to the auditing procedures applied in
the audits of the basic financial statements and, in our opinion, are fairly
stated in all material respects in relation to the basic financial statements
taken as a whole.

The Hanover Companies Retirement Savings Plan
Notes to Financial Statements
December 31, 2001 and 2000

1.   Description of Plan

     The Hanover Companies Retirement Savings Plan (the Plan) was adopted
     effective January 1, 1994 by Hanover Compressor Company (the Company) and
     replaced the Company's former plan, the Hanover Energy Employee's Savings
     Plan.

     The following description of the Plan provides only general information.
     Participants should refer to the Plan document for a more complete
     description of the Plan's provisions.

     General

     The Plan is a defined contribution plan covering all domestic employees of
     the Company. It is subject to the provisions of the Employee Retirement
     Income Security Act of 1974 (ERISA).

     Participation

     A domestic employee of the Company is generally eligible to become a
     participant in the Plan upon attainment of eighteen years of age and six
     months of service with the Company.

     Contributions

     Participants may contribute up to 20% of their pre-tax compensation, as
     defined in the Plan document. Participants may also elect to make rollover
     contributions to the Plan from other qualified retirement plans. The
     Company may make discretionary contributions to the Plan in the form of
     matching contributions of 35% of each participant's contributions for the
     Plan year, up to an annual maximum of $1,000 per individual. Participants
     who were employed on the last day of the Plan year or who died, became
     disabled while an employee of the Company or terminated employment after
     obtaining normal retirement age, as defined in the Plan document, during
     the Plan year are eligible for an allocation of discretionary Company
     contributions. The Company made discretionary contributions of $1,177,493
     during the Plan year ended December 31, 2001.

     Participant contributions may not exceed the maximum statutory limit, which
     was $10,500 for the Plan year ended December 31, 2001. Participants may
     change their contribution percentage on a quarterly basis.

     All Company matching contributions are made in the form of Hanover
     Compressor Company common stock. With regards to the Company matching
     contributions, participants may not withdraw or reallocate such amounts to
     other Plan investment options until the participant terminates
     participation in the Plan.

The Hanover Companies Retirement Savings Plan
Notes to Financial Statements
December 31, 2001 and 2000

     Participant Accounts

     Each participant's account is credited with the participant's
     contributions, Company contributions and an allocation of Plan earnings and
     forfeitures of terminated participants' nonvested accounts. All Plan assets
     are allocated to individual participant account balances. The benefit to
     which a participant is entitled is the benefit that can be provided from
     the participant's vested account balance.

     Vesting

     Participants are immediately vested in their voluntary contributions plus
     actual earnings thereon. Participants become vested in the Company's
     contributions, including reallocated forfeiture accounts, and actual
     earnings thereon at the rate of 20% per year after two years of employment
     with the Company subject to limitations by the Plan document.

     Forfeitures

     Forfeited nonvested Company contributions are allocated to current Plan
     participants on an annual basis based on the ratio of each individual
     participant's total compensation to the total compensation of all eligible
     Plan participants for the Plan year as defined by the Plan document. For
     the year ended December 31, 2001, forfeited nonvested amounts totaling
     $33,947 were allocated to Plan participants. As of December 31, 2001, there
     were $49,732 of forfeited nonvested accounts which had not yet been
     allocated to Plan participants.

     Investment Options

     During the year ended December 31, 2001, participants were able to direct
     their contributions among 23 different investment options consisting of
     Hanover Compressor Company common stock, common/collective trusts and
     mutual funds.

     As further discussed in Note 9, effective December 31, 2001 all of the
     Plan's investments, with the exception of Hanover Compressor Company common
     stock, were converted to cash.

     Payment of Benefits

     A participant may elect to withdraw any part of his or her vested account
     upon retirement, termination of employment, death or disability or
     attainment of age 59 1/2. Benefits may be paid by either a lump-sum amount
     equal to the value of his or her account or periodic installments. A
     lump-sum payment is automatically distributed to terminated participants
     with vested balances equal to or less than $5,000. Withdrawals of vested
     balances due to immediate and heavy financial need are also permitted
     subject to the terms of the Plan document.

                                       F-7

     Participant Loans

     Participants may borrow from their accounts a minimum of $500 up to a
     maximum of the lesser of $50,000 or 50% of the value of the participant's
     vested account balance in the Plan. Loans are secured by the vested balance
     in the participant's account and bear interest at a rate determined by the
     Plan administrator in accordance with the terms of the Plan document. As of
     December 31, 2001 and 2000, the interest rate on outstanding loans ranged
     from 5.0% to 11.5% and 7.5% to 11.5%, respectively. Loan repayments are
     made through payroll deductions and interest paid on loans is credited to
     the applicable participant's account. Participant loans are generally
     repaid over a period not to exceed five years.

     Administration

     The Plan is sponsored by the Company and certain officers and employees of
     the Company serve as the Plan Administrator. The Plan Administrator has the
     power and duty to take all actions and make all decisions necessary to
     properly carry out the provisions of the Plan subject to the terms of the
     Plan document. These powers and duties include, among other things, the
     interpretation of Plan provisions and the engagement of a trustee, record
     keeper, investment manager, legal counsel, independent accountants and
     other such specialists as are deemed necessary for operation of the Plan.

     Merrill Lynch served as the trustee, record keeper and investment manager
     of the Plan. As discussed in Note 9, effective January 1, 2002, Merrill
     Lynch's duties were transferred to INVESCO Retirement, Inc.

     Expenses of the Plan

     Expenses of the Plan are generally paid for by the Company. Administrative
     expenses reflected on the accompanying statement of changes in net assets
     available for benefits for the year ended December 31, 2001 represent the
     sum of charges to individual participant accounts for specific transactions
     initiated by the applicable participants in accordance with the Plan
     document.

2.   Summary of Significant Accounting Policies

     The financial statements of the Plan are prepared on an accrual basis in
     accordance with accounting principles generally accepted in the United
     States of America and in accordance with the provisions of the American
     Institute of Certified Public Accountants Statement of Position 99-3,
     "Accounting for and Reporting of Certain Defined Contribution Plan
     Investments and Other Disclosure Matters." The following is a summary of
     the Plan's significant accounting policies:

     Use of Estimates

     The preparation of the Plan's financial statements in conformity with
     accounting principles generally accepted in the United States of America
     requires the Plan administrator to make estimates and assumptions that
     affect the reported amounts of net assets available for benefits at the
     date of the financial statements and changes in net assets available for
     benefits during the reporting period and, when applicable, disclosures of
     contingent assets and liabilities at the date of the preparation of the
     financial statements. Actual results could differ from those estimates.

     Benefits are recorded when paid.

     Valuation of Investments

     The Plan's investments in mutual funds and Hanover Compressor Company
     common stock are stated at fair market value based on period ending quoted
     market prices. Common/collective trusts are stated at fair market value of
     the applicable trusts' underlying net assets as determined by the quoted
     market prices for securities which market quotations are available or with
     respect to securities for which no quotations are available, fair values as
     determined in good faith by Merrill Lynch. Cash and participant loans are
     valued at cost, which approximates fair market value.

     Investment Income Recognition

     The net appreciation (depreciation) in fair value of investments includes
     the realized gain or loss on investments bought and sold during the year as
     well as the unrealized change in fair value of such investments during the
     year. Purchases and sales of securities are reflected on a trade-date
     basis. Dividend income is recorded on the ex-dividend date and interest
     income is recorded as earned.

     Certain of the Plan's investments pay investment advisory fees and/or 12b-1
     fees and administrative expenses. These fees are reflected in the valuation
     of these investments.

3.   Concentrations of Credit and Market Risk

     Certain investments, including the common stock of the Company, potentially
     subject the Plan to concentrations of credit and market risk. The Plan does
     not obtain or require collateral for these investments. Changes in the
     domestic and international economic environment and other factors outside
     the control of the Plan have a direct impact on the market value and/or
     credit risk of the Plan's investments. It is reasonably possible that
     changes in the economic environment will occur in the near term

     and that such changes will have a material effect on the market value of
     the Plan's investments and/or credit risk relating to such investments.

5.   Plan Mergers

     defined contribution retirement plans into the Plan.

The Hanover Companies Retirement Savings Plan
Notes to Financial Statements
December 31, 2001 and 2000

     Such plans were sponsored by certain of the Company's operating
     subsidiaries prior to the Company's acquisition of these entities. The
     participants in these plans became eligible to participate in the Plan in
     conjunction with the Company's acquisition of the applicable entity. Such
     acquisitions were completed by the Company at various times from 1999 to
     2001.

6.   Plan Termination

     Although it has not expressed any intent to do so, the Company has the
     right under the Plan to discontinue its contribution at any time and to
     terminate the Plan subject to the provisions of ERISA. If the Plan were to
     be terminated in the future, all participants would immediately become
     fully vested in their entire account balance at the time of the Plan's
     termination.

7.   Tax Status

     The Internal Revenue Service has determined and informed the Company by a
     letter dated December 6, 1995 that the Plan is designed in accordance with
     applicable sections of the Internal Revenue Code (IRC). As a result, it is
     believed that the Plan is exempt from taxation under the applicable
     sections of the IRC. The Plan has been amended since receiving the
     determination letter. However, the Plan administrator and the Plan's tax
     counsel believe that the Plan is designed and is currently being operated
     in compliance with the applicable requirements of the IRC.

8.   Party-In-Interest Transactions

     Certain of the Plan's investments are managed by Merrill Lynch, the trustee
     and record keeper of the Plan. Transactions involving these investments
     occur at quoted market values. Consequently, such transactions are
     permitted under the provisions of the Plan and are exempt from prohibition
     of party-in-interest transactions under ERISA.

     Additionally, the Plan provides for investment in shares of the Company's
     common stock. As the Company is the Plan Sponsor, these transactions
     qualify as party-in-interest transactions under ERISA.

9.   Change of Record Keeper, Investment Manager and Trustee

     Effective January 1, 2002, the Plan administrator changed the Plan's
     investment manager, record keeper and trustee from Merrill Lynch to INVESCO
     Retirement, Inc. (INVESCO). As a result of the change, certain of the
     Plan's available investment options were no longer available to
     participants. In preparation for the

     transfer, Merrill Lynch converted all investments, with the exception of
     Hanover Compressor Company common stock, to cash on December 31, 2001. The
     Plan's assets were transferred to INVESCO on January 2, 2002. All
     investment options converted to cash prior to the transfer were mapped to
     investments with similar investment objectives upon receipt of the funds by
     INVESCO.
