of such Person’s willful misconduct, (iv) in the case of the Lender (other than an assignee pursuant to a request by the Borrower under Section 2.18(b)), any U.S. withholding tax that is imposed on amounts payable to such Lender by any law in effect at the time such Lender becomes a party to this Agreement (or designates a new Lending Office), except to the extent that such Lender (or its assignor, if any) was entitled, at the time of designation of a new Lending Office (or assignment), to receive additional amounts from the Borrower with respect to such withholding tax pursuant to this Section 2.15(a), (v) any U.S. federal withholding taxes imposed under FATCA, (vi) [reserved], (vii) taxes attributable to its failure to comply with Section 2.15(f), (g), (i) or (j) and (viii) any interest, penalties or additions to tax imposed on any taxes described in Sections 2.15(a)(i), (ii), (iii), (iv) or (v) (all such taxes, levies, imposts, deductions, charges or withholdings and liabilities with respect thereto not excluded under Section 2.15(a)(i), (ii), (iii), (iv), (v), (vi), (vii) or (viii) in respect of payments hereunder or under the Notes or any other documents to be delivered hereunder being hereinafter referred to as “Taxes”); provided that, if any applicable law (as determined in the good faith discretion of an applicable Withholding Agent) requires a Withholding Agent to deduct any taxes, levies, imposts, deductions, charges or withholdings, or any liabilities with respect thereto, from or in respect of any sum payable by or on account of any obligation of the Borrower hereunder or under any Note or any other documents to be delivered hereunder to or for the account of the Lender, (i) the Withholding Agent shall be entitled to make such deduction and shall timely pay the full amount deducted to the relevant taxation authority or other authority in accordance with applicable law and (ii) to the extent such deduction is for Taxes or Other Taxes (as hereinafter defined), the sum payable by the Borrower shall be increased as may be necessary so that after making all required deductions (including deductions applicable to additional sums payable under this Section 2.15) such Lender receives an amount equal to the sum it would have received had no such deductions for Taxes or Other Taxes been made.

(b)    In addition, the Borrower shall pay any present or future stamp or documentary taxes or any other excise or property taxes, charges or similar levies that arise from any payment made hereunder or under the Notes or any other documents to be delivered hereunder or from the execution, delivery or registration of, performing under, or otherwise with respect to, this Agreement or the Notes or any other documents to be delivered hereunder, excluding, however, such taxes imposed with respect to an assignment following the primary syndication (other than an assignment that occurs as a result of the Borrower’s request pursuant to Section 2.18) that would not have been imposed but for a present or former connection between the Lender and the jurisdiction imposing such taxes (other than solely on account of the execution, delivery or registration of, performing under, or otherwise with respect to, this Agreement or the Notes or any other documents to be delivered hereunder) (hereinafter referred to as “Other Taxes”).

(c)    The Borrower shall indemnify the Lender for and hold it harmless against the full amount, without duplication, of Taxes or Other Taxes (including, without limitation, Taxes of any kind imposed or asserted by any jurisdiction on amounts payable under this Section 2.15) imposed on or paid by Lender and any liability (including penalties and interest) arising therefrom or with respect thereto. This indemnification shall be made within 30 days from the date the Lender makes written demand therefor and provides appropriate computational and, to the extent available, documentary support.

(d)    As soon as practicable after any payment of Taxes or Other Taxes pursuant to this Section 2.15, the Borrower shall furnish to the Lender, at its address referred to in Section 8.02, the original or a certified copy of a receipt evidencing such payment to the extent that such a receipt is issued therefor, or other written proof of payment thereof that is reasonably satisfactory to the Lender.

(e)    [reserved].

(f)    If the Lender is entitled to an exemption from or reduction of withholding tax with respect to payments made hereunder or under the Notes or any other documents to be delivered hereunder shall deliver to the Borrower, at the time or times reasonably requested by the Borrower, such properly completed and executed documentation reasonably requested by the Borrower as will permit such payments to be made without withholding or at a reduced rate of withholding. In addition, the Lender, if reasonably requested by the Borrower, shall deliver such other documentation prescribed by applicable law or reasonably requested by the Borrower as will enable the Borrower to determine whether or not the Lender is subject to backup withholding or information reporting requirements. Notwithstanding anything to the contrary in the preceding two sentences, the completion, execution and submission of such documentation (other than such documentation set forth in Sections 2.15(h) and (i) below) shall not be required if in the Lender’s reasonable judgment such completion, execution or submission would subject such Lender to any material unreimbursed cost or expense or would materially prejudice the legal or commercial position of such Lender.

(g)    [reserved].

(h)    If a payment made to the Lender hereunder or under the Notes or any other documents to be delivered hereunder would be subject to U.S. federal withholding tax imposed by FATCA if the Lender were to fail to comply with the applicable reporting requirements of FATCA (including those contained in Section 1471(b) or 1472(b) of the Internal Revenue Code, as applicable), the Lender shall deliver to the Borrower at the time or times prescribed by law and at such time or times reasonably requested by the Borrower such documentation prescribed by applicable law (including as prescribed by Section 1471(b)(3)(C)(i) of the Internal Revenue Code) and such additional documentation reasonably requested by the Borrower as may be necessary for the Borrower to comply with their obligations under FATCA and to determine that the Lender has complied with the Lender’s obligations under FATCA or to determine the amount to deduct and withhold from such payment. Solely for purposes of this paragraph (h), “FATCA” shall include any amendments made to FATCA after the date of this Agreement.

(i)    The Lender shall deliver at the time(s) and in the manner(s) prescribed by applicable law, to the Borrower two original properly completed and duly executed United States Internal Revenue Service Forms W-9 or any successor form, certifying that such Person is exempt from United States backup withholding tax on payments made hereunder.

(j)    The Lender agrees that if any form or certification it previously delivered pursuant to Section 2.15(f), (h) or (i) expires or becomes obsolete or inaccurate in any respect, it

shall update such form or certification or promptly notify the Borrower in writing of its legal inability to do so.

(k)    For the avoidance of doubt, for any period with respect to which the Lender has failed to provide the Borrower with the appropriate form, certificate or other document described in Section 2.15(i) (other than if such failure is due to a change in law occurring subsequent to the date on which a form, certificate or other document originally was required to be provided, or if such form, certificate or other document otherwise is not required under Section 2.15(i)), such Lender shall not be entitled to increased payments or indemnification under Section 2.15(a) or (c) with respect to taxes or Other Taxes imposed by reason of such failure; provided, however, that the Borrower shall take such steps as the Lender shall reasonably request (at the sole expense of such Lender) to assist the Lender to recover such taxes or Other Taxes (it being understood, however, that the Borrower shall have no liability to such Lender in respect of such taxes or Other Taxes).

(l)    If any party determines, in its sole discretion exercised in good faith, that it has received a refund of any Taxes or Other Taxes as to which it has been indemnified pursuant to this Section 2.15 (including by the payment of additional amounts pursuant to this Section 2.15), it shall pay to the indemnifying party an amount equal to such refund (but only to the extent of indemnity payments made by such indemnifying party under this Section with respect to the Taxes or Other Taxes giving rise to such refund), net of all out-of-pocket expenses (including taxes) of such indemnified party and without interest (other than any interest paid by the relevant governmental authority with respect to such refund). Such indemnifying party, upon the request of such indemnified party, shall repay to such indemnified party the amount paid over pursuant to this paragraph (l) (plus any penalties, interest or other charges imposed by the relevant governmental authority) in the event that such indemnified party is required to repay such refund to such governmental authority. Notwithstanding anything to the contrary in this paragraph (l), in no event will the indemnified party be required to pay any amount to an indemnifying party pursuant to this paragraph (l) the payment of which would place the indemnified party in a less favorable net after-tax position than the indemnified party would have been in if the Tax or Other Tax subject to indemnification and giving rise to such refund had not been deducted, withheld or otherwise imposed and the indemnification payments or additional amounts with respect to such Tax or Other Tax had never been paid.

(m)    [reserved].

(n) For purposes of determining withholding taxes imposed under FATCA, the Borrower shall treat (and the Lender hereby authorize the Borrower to treat) this Agreement and any Advance as not qualifying as a “grandfathered obligation” within the meaning of Treasury Regulation Section 1.1471-2(b)(2)(i).

Nothing contained in this Section 2.15 shall require the Lender to make available its tax returns (or any other information relating to its taxes which it deems to be confidential).

SECTION 2.16.    [reserved].

SECTION 2.17.    Notes.The Borrower agrees that upon notice by the Lender to the Borrower to the effect that a promissory note or other evidence of indebtedness is required or appropriate in order for the Lender to evidence (whether for purposes of pledge, enforcement or otherwise) the Advances owing to, or to be made by, the Lender, the Borrower shall promptly execute and deliver to the Lender a Note payable to the Lender.

SECTION 5.09.    Use of Proceeds.

The proceeds of the Advances made under this Agreement will be used by the Borrower for its and its Subsidiaries’ general company purposes.

SECTION 5.10.    [reserved].

SECTION 5.11.    Consolidated Leverage Ratio.

(a)    The Consolidated Leverage Ratio, as at the end of each fiscal quarter of the Borrower (beginning with the fiscal quarter ended September 30, 2013), shall be less than or equal to 5.00 to 1.0; provided that subsequent to the consummation of a Qualified Acquisition, the Consolidated Leverage Ratio, as at the end of the three consecutive fiscal quarters following such Qualified Acquisition, shall be less than or equal to 5.50 to 1.0.

twelve-month period of determination; provided, that with respect to all Permitted Acquisitions with limited or no prior operating history (or with a prior operating history that does not reliably indicate future operating results), Consolidated EBITDA shall be deemed to be the amount approved by the Lender as the projected Consolidated EBITDA of the Borrower and its Subsidiaries attributable to such Permitted Acquisition for the first twelve-month period following such Permitted Acquisition (such amount to be determined based on customer contracts relating to such Permitted Acquisition, the creditworthiness of the other parties to such contracts, and projected revenues from such contracts, capital costs and expenses, oil and gas reserve and production estimates, commodity price assumptions and other reasonable factors deemed appropriate by the Lender); and

(ii)    Consolidated EBITDA may include, at the Borrower’s option, any Qualified Project EBITDA Adjustments as provided in the definition thereof.

SECTION 5.12.    Designation of Subsidiaries.

The Board of Directors or similar governing body of the Ultimate General Partner (in its capacity as general partner of the General Partner, in its capacity as general partner of the Borrower) may at any time designate any Restricted Subsidiary as an Unrestricted Subsidiary or any Unrestricted Subsidiary as a Restricted Subsidiary; provided that (i) immediately before and after such designation, no Event of Default or Default shall have occurred and be continuing, (ii) immediately after giving effect to such designation, the Borrower and its Restricted Subsidiaries shall be in compliance, on a pro forma basis, with Section 5.11(a) (as though the effective date of such designation were the last day of a fiscal quarter of the Borrower) and, as a condition precedent to the effectiveness of such designation, the Borrower shall deliver to the Agent a certificate of the Chief Financial Officer, Treasurer or Controller of the Ultimate General Partner (in its capacity as general partner of the General Partner, in its capacity as general partner of the Borrower) setting forth in reasonable detail the calculations demonstrating such compliance), (iii) no Restricted Subsidiary may be designated as an Unrestricted Subsidiary if it was previously designated an Unrestricted Subsidiary, (iv) no Subsidiary of an Unrestricted Subsidiary may be designated as a Restricted Subsidiary, (v) no Subsidiary that owns any Equity Securities or Indebtedness of, or owns or holds any Lien on, any property of the Borrower or any Restricted Subsidiary (other than any Subsidiary of the Subsidiary to be so designated), may be designated an Unrestricted Subsidiary, (vi) each Subsidiary to be so designated as an Unrestricted Subsidiary, and its Subsidiaries, has not at the time of designation, and does not thereafter, create, incur, issue, assume, guarantee or otherwise become directly or indirectly liable with respect to any Indebtedness pursuant to which the lender or other creditor has recourse to any assets of the Borrower or any Restricted Subsidiary other than the Equity Securities in such Unrestricted Subsidiary and its Subsidiaries, and (vii) no primary operating Subsidiary of the Borrower may be designated as an Unrestricted Subsidiary. The designation of any Unrestricted Subsidiary as a Restricted Subsidiary shall constitute the incurrence at the time of designation of any Indebtedness or Liens of such Subsidiary existing at such time. If, at any time, any Unrestricted Subsidiary fails to meet the preceding requirements as an Unrestricted Subsidiary, it will thereafter automatically cease to be an Unrestricted Subsidiary and shall constitute a Restricted Subsidiary for all purposes of this Agreement, and (among other things)

any Indebtedness and Liens of such Subsidiary will be deemed to be incurred by a Restricted Subsidiary of the Borrower as of such date.

SECTION 5.13.    [reserved].

then, and in every such event (other than an event with respect to the Borrower described in Section 6.01(e)), and at any time thereafter during the continuance of such event, the Lender may, by notice to the Borrower, take any or all of the following actions, at the same or different times: (i) terminate the Commitment, and thereupon the Commitment shall terminate immediately, (ii) exercise their rights and remedies under Section 2.03(h)(i), and (iii) declare the Revolving Advances then outstanding to be due and payable in whole (or in part, in which case any principal not so declared to be due and payable may thereafter be declared to be due and payable so long as, at the time of such later declaration, an Event of Default is continuing), and thereupon the principal of the

Any Person required to maintain the confidentiality of Information as provided in this Section 8.13 shall be considered to have complied with its obligation to do so if such Person has exercised the same degree of care to maintain the confidentiality of such Information as such Person would accord to its own confidential information.

(b)    The Lender acknowledges that Information furnished to it pursuant to this Agreement may include material non-public information concerning the Borrower and its Affiliates or their respective securities, and confirms that it has developed compliance procedures regarding the use of material non-public information and that it will handle such material non-public information in accordance with those procedures and applicable law, including Federal and state securities laws.

(a)    If, for the purpose of obtaining judgment in any court, it is necessary to convert a sum owing hereunder in one currency into another currency, each party hereto agrees, to the fullest extent that it may effectively do so, that the rate of exchange used shall be that at which in accordance with normal banking procedures in the relevant jurisdiction the first currency could be purchased with such other currency on the Business Day immediately preceding the day on which final judgment is given.

(b)    The obligations of the Borrower in respect of any sum due to any party hereto or any holder of the obligations owing hereunder (the “Applicable Creditor”) shall, notwithstanding any judgment in a currency (the “Judgment Currency”) other than the currency in which such sum is stated to be due hereunder (the “Agreement Currency”), be discharged only to the extent that, on the Business Day following receipt by the Applicable Creditor of any sum adjudged to be so due in the Judgment Currency, the Applicable Creditor may in accordance with normal banking procedures in the relevant jurisdiction purchase the Agreement Currency with the Judgment Currency; if the amount of the Agreement Currency so purchased is less than the sum originally due to the Applicable Creditor in the Agreement Currency, the Borrower agrees, as a separate obligation and notwithstanding any such judgment, to indemnify the Applicable Creditor against such loss. The obligations of the Borrower contained in this Section 8.14 shall survive the termination of this Agreement and the payment of all other amounts owing hereunder.

IN WITNESS WHEREOF, the parties hereto have caused this Agreement to be executed by their respective officers thereunto duly authorized, as of the date first above written.

The Borrower promises to pay interest on the unpaid principal amount of each Revolving Advance from the date of such Revolving Advance until such principal amount is paid in full, at such interest rates, and payable at such times, as are specified in the Credit Agreement.

Both principal and interest are payable in lawful money of the United States of America to the Lender, in same day funds. Each Revolving Advance owing to the Lender by the Borrower pursuant to the Credit Agreement, and all payments made on account of principal thereof, shall be recorded by the Lender and, prior to any transfer hereof, endorsed on the grid attached hereto that is part of this Promissory Note; provided that the failure to make a notation of any such Revolving Advance or payment made on this Promissory Note shall not limit or otherwise affect the obligations of the Borrower hereunder with respect to payments of principal of or interest on this Promissory Note.

This Promissory Note is entitled to the benefits of, the Credit Agreement. The Credit Agreement, among other things, (i) provides for the making of Revolving Advances by the Lender to the Borrower from time to time in an aggregate amount not to exceed at any time outstanding the dollar amount first above mentioned, the indebtedness of the Borrower resulting from each such Revolving Advance by the Lender being evidenced by this Promissory Note, and (ii) contains provisions for acceleration of the maturity hereof upon the happening of certain stated events and also for prepayments on account of principal hereof prior to the maturity hereof upon the terms and conditions therein specified.

This Promissory Note shall be construed in accordance with and governed by the law of Texas.

The terms of this Promissory Note are subject to amendment only in the manner provided in the Credit Agreement. The Borrower promises to pay all reasonable and invoiced out-of-pocket fees, charges and expenses, all as provided in the Credit Agreement, of counsel retained

by the Lender in connection with the collection and enforcement of this Promissory Note (whether through negotiations, legal proceedings or otherwise). The Borrower and any endorsers of this Promissory Note hereby consent to renewals and extensions of time at or after the maturity hereof, without notice, and hereby waive diligence, presentment, protest, demand, notice of every kind and, to the full extent permitted by law, the right to plead any statute of limitations as a defense to any demand hereunder.
