Dear John:

This letter summarizes Hanover Compressor Company's offer of employment to you

and policies, financial and management reporting, internal controls, treasury
and finance activities, tax planning and compliance, and information technology.
This position will also entail your management of the Company's capital
structure, commercial and investment banking relationships, external financing
and relations with investors, ratings agencies and other parties essential to
the Company's capital formation. Additionally, as a critical member of the
Company's senior executive management team you will be involved with and
responsible for the budgeting and planning activities of the Company, working
with other Hanover senior managers to accomplish the business development and

Base Salary:        $11,538.47 per pay period (26 pay periods per year).

                    Company performance and personal performance compared with
                    agreed upon objectives and subjective measures. Provided
                    such agreed upon performance objectives are met, target
                    annual profit sharing payout shall be 50% of annual base

                    2002 will be $75,000.

                    Note that the Company may reclaim this amount if you

                    Reason" within 12 months of your employment start date.

                    yourself without a third party broker. The Company will also
                    assume financial responsibility for loan application,
                    origination and title insurance costs and miscellaneous
                    warranty, appraisal and related fees related to your
                    purchase of a new residence in Houston. Additionally, to
                    help facilitate your family's relocation to Houston, the
                    Company will reimburse you for reasonable out-of-pocket
                    travel and related living expenses for a period of up to
                    twelve months following your start date. The Company will
                    provide an income tax gross up to you on taxes that may be
                    owed resulting from taxable relocation-related expenses. The
                    Company will not reimburse you for property, school and
                    personal taxes, related to the sale of your existing primary
                    residence.

                    Total Company reimbursement for the above-referenced
                    relocation and related costs, excluding transitional,
                    temporary living and related travel expense or any "tax
                    gross-up" (see below) incurred within eighteen months of
                    your employment start date shall be capped at $60,000.
                    Whenever possible, these costs will be billed directly to
                    the Company. To the extent that payment of these costs
                    result in taxable relocation expense to you, the Company
                    agrees to provide an income tax gross up to you for such
                    personal taxes paid by you. Note that the Company may
                    reclaim this relocation payment if you terminate your
                    employment with the Company without "Good Reason" within 12
                    months of your employment date.

Auto Allowance:     Either $500 per month or company furnished vehicle (TBD).

Vacation:           Up to four weeks per year.

Employment
Agreement:          An agreement obligating the Company to make a severance
                    payment to you equal to one and one-half times your
                    annualized salary and bonus compensation in the event that
                    you involuntarily terminate your employment with the Company
                    within the first twelve months following a "Change of
                    Control" of the Company. This agreement will not obligate
                    the Company to make a severance payment to you in the event
                    that you voluntarily terminate your employment with the
                    Company without "Good Reason" or involuntarily terminate
                    your employment with the Company due to your death,
                    disability, or termination for "Cause". The agreement will
                    be paired with a non-competition agreement, which shall
                    preclude you from employment in

                    Hanover's principal lines of business for a period one year
                    after you terminate your employment with the Company
                    employment and shall terminate the above-referenced
                    severance payment to you in the event that you violate this
                    non-compete agreement.

                    For purposes of this letter, voluntary termination of
                    employment for "Good Reason" shall be defined as any
                    situation in which your termination of employment with the
                    Company (i) promptly follows a material reduction of your
                    duties and responsibilities or a permanent change in your
                    duties and responsibilities which are materially
                    inconsistent with the type of duties and responsibilities
                    then in effect, (ii) promptly follows a material reduction
                    in your annual base salary (without regard to bonus
                    compensation, if any), (iii) promptly follows a material
                    reduction in your employee benefits (without regard to bonus
                    compensation, if any) if such reduction results in you
                    receiving benefits which are, in the aggregate, materially
                    less than the benefits received by other comparable
                    employees of the Company generally or (iv) the Board
                    otherwise determines that a voluntary termination by you is
                    for "Good Reason" under the circumstances then prevailing.

Additionally, as a full time employee, you will also be eligible to participate
in the various benefit programs offered by the Company. Enclosed please find a
summary of those programs. During the initial three-month eligibility waiting
period for health benefits, the Company will reimburse you for your actual cost
of continuing your current employer's health coverage under the Consolidated
Omnibus Reconciliation Act (COBRA) option. Pursuant to Company and ERISA
guidelines, your eligibility for participating in the Company's 401(k) plan will
occur on the 1st of the month following six months of service with the Company.

John, this offer is contingent upon providing Hanover with the required
documentation to complete the INS I-9 Form and the successful completion of a
drug screen. These activities, along with a full discussion of benefits and the
related forms, can be accomplished by calling me or Errol Robinson, Director of
Human Resources in the Hanover's corporate office at 281/447-8787.

Again, we are extremely confident that if your decision is to accept this offer,
it will prove to be mutually rewarding. Your inclusion in Hanover's senior
executive management group represents a very significant addition to the Company
step and an excellent opportunity for both you and the Company.

This position will also entail your joint management of the Company's

formation and business development. Finally, as a critical member of the
Company's senior executive management team you will be involved with and
responsible for developing, implementing and managing the plans, policies and

                    periods per year).

Profit Sharing
Opportunity:        25 - 100% of annual base salary to be paid annually based
                    upon personal performance determined by the Company's board
                    of directors compared with agreed upon personal performance
                    objectives and subjective measures as well as Company
                    performance. Target annual profit sharing payout shall be
                    50% of annual base salary (provided such agreed upon
                    performance objectives are met); and (as specified above)
                    you will have the opportunity for a bonus of up to 100% of
                    base for superior performance. Notwithstanding the
                    provisions described above, your minimum profit sharing
                    payment for performance during 2002 will be $150,000.
                    Thereafter, the minimum annual profit sharing payment to
                    which you shall be entitled, if any, shall be set each year

                    NYSE closing market price that day. As of your start date,
                    you and the Company will enter into the attached Stock
                    Option Agreement to evidence such option grant. In addition,
                    provided that you remain continually employed by the Company

Mr. Mark S. Berg

                    full opportunity to participate in the stock, compensation,
                    incentive, retirement and other plans and benefits offered
                    to the most senior officers of the Company; provided,
                    however, that you will not be eligible to participate in any
                    stock option grants made within 6 months of your start date
                    unless other senior executives of the Company who were hired
                    in 2002 also participate. As we have discussed, the
                    Compensation Committee of the Company's Board of Directors
                    intends to evaluate Hanover's management compensation plans
                    generally and you will be a meaningful participant in those
                    discussions as well as in the programs that are implemented
                    as a result thereof.

Severance
Agreement:          The Company will make a severance payment to you in a lump
                    sum, as soon as practicable following your termination,
                    equal to one and one-half times your annualized salary and
                    Bonus Compensation in the event that you involuntarily
                    terminate your employment with the Company within the first
                    twelve months following a "Change of Control" of the
                    Company. Additionally, the Company will make a severance
                    payment to you in a lump sum, as soon as practicable
                    following your termination, equal to one times your
                    annualized salary and Bonus Compensation in the event that
                    you involuntarily terminate your employment with the Company
                    in the absence of a Change of Control. In either of these
                    two events, the Company shall provide you (at its sole cost)
                    your current health benefits for a period of eighteen months
                    following your termination date, with such continuation of
                    benefits being concurrent with and not in addition to any
                    continuation coverage required by law. In calculating
                    severance, "Bonus Compensation" will equal the average bonus
                    paid to you for the two annual periods occurring immediately
                    prior to your termination of employment (or prior to the
                    Change in Control, if applicable). If two periods have not
                    transpired, the Bonus Compensation will equal the bonus paid
                    to you for 2002 and if the 2002 bonus has not been paid,
                    Bonus Compensation will be $300,000.

                    Please note, however, that the Company will not be obligated
                    to make any severance payment to you in the event that you
                    voluntarily terminate your employment with the Company
                    without "Good Reason" or involuntarily terminate your
                    employment with the Company due to your death, disability,
                    or are terminated for "Cause". Additionally, in the event
                    that the Company subsequently implements employment
                    contracts or benefits for its

<PAGE>

                    executive managers that contain Change of Control-related
                    protections more favorable to managers than that described
                    above, you will be offered similar protections.

                    These commitments regarding your severance are in
                    consideration for your agreement that, during the term of
                    your employment and for a period one year after you
                    terminate your employment with the Company, for whatever
                    reason, you will not provide services as an employee,
                    consultant, advisor, partner or member of any entity whose
                    primary business is directly competitive with that of the
                    Company's or any subsidiary of the Company (a "Competitor")
                    with regard to the natural gas compression services business
                    ("Competitive Services"); provided, however, that this
                    covenant will not (i) restrict you from providing services
                    to any Competitor if such services are provided to a line of
                    business of the Competitor that is not related to the
                    natural gas compression services businesses or (ii) not
                    prohibit you from entering into the private practice of law
                    or providing legal services to a Competitor so long as in
                    connection with the provision of such services you do not
                    disclose or otherwise use any confidential or proprietary
                    information of the Company. This agreement on your part will
                    apply regardless of whether your employment terminates under
                    circumstances, which entitle you to receive the severance
                    payments described above. The Company will have all rights
                    and remedies available to it at law and in equity to assure
                    your compliance with this covenant and to remedy any breach
                    thereof, including, without limitation, the right to enforce
                    this covenant by injunctive relief. In the event that you
                    breach the foregoing covenant regarding non-competition, the
                    Company shall no longer be obligated to provide you
                    continued health benefits under this Agreement. This
                    non-competition covenant will control over any other
                    non-competition agreements in the Company's plans and
                    policies, including the Stock Option Agreement executed by
                    you.

                    For purposes of this letter, voluntary termination of
                    employment for "Good Reason" shall be defined as any
                    situation in which your termination of employment with the
                    Company (i) promptly follows a material reduction of your
                    duties and responsibilities or a permanent change in your
                    duties and responsibilities which are materially
                    inconsistent with the type of duties and responsibilities
                    then in effect, (ii) promptly follows a reduction in your
                    annual base salary (without regard to bonus compensation, if
                    any) or a reduction in your annual bonus opportunity as set
                    forth in this letter (it is acknowledged that a reduction in
                    the actual amount of your bonus from year to year as a
                    result of performance will not be considered a reduction in
                    bonus opportunity), (iii) promptly

<PAGE>

                    follows a material reduction in your employee benefits
                    (without regard to bonus compensation, if any) if such
                    reduction results in you receiving benefits which are, in
                    the aggregate, materially less than the benefits received by
                    other comparable employees of the Company generally, (iv)
                    promptly follows a material failure by the Company to comply
                    with the terms of this letter or to pay any compensation
                    when due, but only after you provide notice to the Company
                    of such failure and the Company has reasonable opportunity
                    to cure, (v) promptly follows a relocation of your principal
                    work location outside the Houston, Texas metropolitan area,
                    or (vi) the Board otherwise determines that a voluntary

                    circumstances then prevailing.
