EXTERRAN GUARANTEE

     The Original Indenture is hereby amended and supplemented by adding the following as Article XVII of the Original Indenture:

ARTICLE XVII

EXTERRAN GUARANTEE

SECTION 17.01. Exterran Guarantee.

     Subject as provided in the final paragraph of this Section 17.01, Exterran fully and unconditionally guarantees to each Holder of a Security authenticated and delivered by the Trustee and to the Trustee and its successors and assigns, irrespective of the validity and enforceability of this Indenture, the Securities held thereby and the obligations of the Company hereunder and thereunder, that the principal of and interest on the Securities will be promptly paid in full when due, subject to any applicable grace period, whether at final maturity, by acceleration, redemption or otherwise, and interest on the overdue principal of and interest (to the extent permitted by law) on the Securities, and all other payment obligations of the Company to the Holders or the Trustee hereunder or thereunder, will be promptly paid in full, all in accordance with the terms hereof and thereof. Failing payment when so due of any amount so guaranteed for whatever reason, Exterran will be obligated to pay the same immediately. An Event of

Default under this Indenture or the Securities shall constitute an event of default under this guarantee, and shall entitle the Holders to accelerate the obligations of Exterran hereunder in the same manner and to the same extent as the obligations of the Company. Exterran agrees that its obligations hereunder shall be unconditional, irrespective of the validity, regularity or enforceability of the Securities or this Indenture, the absence of any action to enforce the same, any waiver or consent by any Holder with respect to any provisions hereof or thereof, the recovery of any judgment against the Company, any action to enforce the same or any other circumstance (other than complete performance) which might otherwise constitute a legal or equitable discharge or defense of Exterran. Exterran further, to the extent permitted by law, waives diligence, presentment, demand of payment, filing of claims with a court in the event of insolvency or bankruptcy of the Company, any right to require a proceeding first against the Company, protest, notice and all demands whatsoever and covenants that this guarantee will not be discharged except by complete performance of the payment obligations contained in the Securities and this Indenture. If any Holder or the Trustee is required by any court or otherwise to return to the Company, Exterran, the Trustee or any custodian or other similar official acting under any applicable bankruptcy law in relation to either the Company or Exterran, any amount paid by the Company or Exterran to the Trustee or such Holder, this guarantee, to the extent theretofore discharged, shall be reinstated in full force and effect. Exterran agrees that it shall not be entitled to, and waives, any right of subrogation in relation to the Holders in respect of any obligations guaranteed hereby until payment in full of the obligations guaranteed hereby. Exterran further agrees that, as between itself, on the one hand, and the Holders and the Trustee, on the other hand, (a) the maturity of the obligations guaranteed hereby may be accelerated as provided in Section 402 of the Second Supplemental Indenture for the purposes of acceleration this guarantee, notwithstanding any stay, injunction or other prohibition preventing such acceleration in respect of the obligations guaranteed thereby, and (b) in the event of any declaration of acceleration of such obligations as provided in Section 402 of the Second Supplemental Indenture, such obligations (whether or not due and payable) shall forthwith become due and payable by Exterran for the purpose of this guarantee.

     This guarantee of Exterran is a continuing guarantee and shall remain in full force and effect and shall be binding upon Exterran and its respective successors and assigns to the extent set forth in this First Supplemental Indenture until full and final payment of all of the Company’s obligations under the Securities and the Indenture and shall inure to the benefit of the successors and assigns of the Trustee and the Holders and, in the event of any transfer or assignment of rights by any Holder or the Trustee, the rights and privileges conferred in this First Supplemental Indenture upon that party shall automatically extend to and be vested in such transferee or assignee, all subject to the terms and conditions hereof. This guarantee of Exterran is a guarantee of payment and not a guarantee of collection.

     This guarantee of Exterran is not intended to constitute a fraudulent transfer or conveyance of purposes of any applicable bankruptcy law, the Uniform Fraudulent Conveyance Act, the Uniform Fraudulent Transfer Act or any similar federal, state, or foreign law to the extent applicable to Exterran’s guarantee. To effectuate the foregoing

intention, the obligations of Exterran under this guarantee shall be limited to the maximum amount as will, after giving effect to such maximum amount and all other contingent and fixed liabilities of Exterran that are relevant under such laws, result in the obligations of Exterran under this guarantee not constituting a fraudulent transfer or conveyance. In addition, the obligations of Exterran under this guarantee shall be limited to the extent required by applicable law.
