Re:          Employment Terms

Dear [Name]:

As you know, Exterran Holdings, Inc. (to be renamed Archrock, Inc.), a Delaware corporation (the “Company”) is spinning off a new publicly-traded company, Exterran Corporation (“SpinCo” and such spin-off, the “Spin-Off”), which will own the assets and liabilities associated with the Company’s international services and global fabrication businesses.  In connection with the Spin-Off, and effective as of the effective time of the Spin-Off (the “Effective Time”), I am pleased to offer you the position of [      ] of the Company, on the terms and conditions set forth below.

1.   POSITIONS, DUTIES AND RESPONSIBILITIES.  As of the Effective Time, you will serve as [      ] of the Company, and will have such duties and responsibilities as are usual and customary for your position.  You will report directly to the [         ]of the Company, and will work at the Company’s offices located in Houston, Texas, except for travel to other locations as may be reasonably necessary to fulfill your responsibilities.  At the Company’s request, you will serve the Company and/or its subsidiaries and affiliates in other offices, directorships and capacities in addition to the foregoing.  In the event that you serve in any one or more of such additional capacities, your compensation will not be increased beyond that specified in this letter.  You will be expected to devote your full business time and attention to the business and affairs of the Company and the performance of your duties hereunder.

2.   AT-WILL EMPLOYMENT.  You acknowledge and agree that your employment with the Company is “at-will” and not for any specified time, and may be terminated, with or without cause and with or without notice, at any time by you or the Company; provided, however, that you will be entitled to certain benefits and payments upon certain terminations of employment, as described in paragraphs 8 and 9 below.  The nature of your at-will employment relationship cannot be changed except in a writing signed by you and an authorized representative of the Company.

3.   BASE COMPENSATION.  During your employment with the Company, your base salary will be as set forth on Exhibit A attached hereto (the “Base Salary”), less payroll deductions and all required withholdings, payable in accordance with the Company’s normal payroll practices but no less often than bi-weekly.  Your Base Salary will be subject to annual

review in the discretion of the board of directors of the Company (the “Board”) or a designated committee of the Board.

4.   SHORT-TERM INCENTIVE.  For each fiscal year of the Company ending during the term of your employment, you will be eligible to receive an annual short-term incentive payment (the “Short-Term Incentive”) upon the achievement of performance objectives to be determined by the Company’s Chief Executive Officer and/or the Board or a designated committee of the Board, which will be targeted at a percentage of your Base Salary as set forth on Exhibit A attached hereto (the “Target Short-Term Incentive”), subject to annual review in the discretion of the Board or a designated committee of the Board.  Any such Short-Term Incentive will be paid on the date on which short-term incentives are paid generally to the Company’s executive officers, but in no event later than the fifteenth (15th) day of the third (3rd) month following the end of the fiscal year in which the Short-Term Incentive is earned and, unless otherwise agreed to by the Board or a designated committee of the Board, you must be employed by the Company on the payment date in order to earn such bonus.

5.             [FOR ALL CASH RETENTION AWARD: RETENTION PAYMENT.  As a key employee, you will be eligible to receive a cash payment in the aggregate amount set forth on Exhibit A attached hereto (the “Retention Payment”), subject to the terms and conditions herein.

(a)           Payments. The Retention Payment will be paid to you in installments as follows: (i) thirty-three percent (33%) of the Retention Payment will be paid to you on, or within thirty (30) days following, the date on which the Effective Time occurs (the “Effective Date”); (ii) thirty-three percent (33%) of the Retention Payment will be paid to you on, or within thirty (30) days following, the first (1st) anniversary of the Effective Date (the “First Anniversary”); and (iii) thirty-four percent (34%) of the Retention Payment will be paid to you on, or within thirty (30) days following, the second (2nd) anniversary of the Effective Date (the “Second Anniversary”), in each case, subject to your continued employment with the Company through the Effective Date, the First Anniversary or the Second Anniversary, as applicable (each such date, a “Service Date”).

(b)           Accelerated Payments. Notwithstanding anything in Section 5(a) to the contrary:

(i) Without Cause or for Good Reason.  If your employment is terminated by the Company without Cause or you resign for Good Reason (each, as defined in your Change of Control Agreement or Severance Agreement (each, as defined below), as applicable), in either case, prior to the Second Anniversary, you will be entitled to receive, in addition to any payments or benefits for which you are eligible under your Severance Agreement and/or Change of Control Agreement, as applicable, an amount (the “Excess Amount”) equal to the excess, if any, of (i) the then-unpaid portion of your Retention Payment (excluding any unpaid portion for which a Service Date has occurred prior to your termination of employment) over (ii) either (x) the aggregate amount of the “Severance Payment” (as defined in your Severance Agreement) that you are entitled to receive upon such termination under your Severance Agreement or (y) the aggregate amount of cash severance that you are entitled to receive upon such termination under your Change of Control Agreement, as applicable.  The Excess

2

Amount will be paid to you on or within thirty (30) days following the date of your termination of employment.

(ii)           Death or Disability. If your employment with the Company terminates due to your death or Disability (as defined below) prior to the Second Anniversary, you (or your estate, as applicable) will be entitled to receive a pro-rated portion of your Retention Payment (the “Pro-Rated Amount”) determined by multiplying (i) the amount of the Retention Payment that you otherwise would have been eligible to receive on the next Service Date to occur following your termination of employment, had such termination not occurred, multiplied by (ii) a fraction, the numerator of which is the number of days elapsed between the most recent Service Date and the date on which your termination of employment occurs and the denominator of which is 365.  The Pro-Rated Amount will be paid to you (or your estate) on or within thirty (30) days following the date of your termination of employment.  For purposes of this Section 5, “Disability” means that you are “disabled” within the meaning of Section 409A of the Internal Revenue Code of 1986, as amended.

(iii)          No Offset.  For the avoidance of doubt, notwithstanding anything to the contrary in your Severance Agreement and/or Change of Control Agreement, any amounts that may be or become payable to you under this Section 5 will not offset any cash severance payments payable to you under your Severance Agreement and/or Change of Control Agreement.

(c)           Termination of Employment. Except as otherwise set forth in Section 5(b) above, upon your termination of employment, you will forfeit any then-unpaid portion of your Retention Payment, excluding any unpaid portion for which a Service Date has occurred prior to your termination of employment.  For purposes of clarity, any transfer of your employment between SpinCo and the Company (and/or their affiliates) prior to, on or following the Effective Time will not constitute a termination of your employment with the Company for purposes of this Section 5.]
