In addition, the Company or the Manager may, upon notice to the other party hereto by telephone (confirmed promptly by email or facsimile), suspend an offering of the Units pursuant to this Agreement; provided, however, that such suspension or termination shall not affect or impair the parties’ respective obligations with respect to the Units sold hereunder prior to the giving of such notice.

(b) Before amending or supplementing each Registration Statement or the Prospectus (which, for avoidance of doubt, shall not include the filing of any reports or any definitive proxy statement required to be filed by the Company with the Commission pursuant to Section 13(a), 13(c), 14 or 15(d) of the Exchange Act), to furnish to the Manager a copy of each such proposed amendment or supplement and not to file any such proposed amendment or supplement to which the Manager reasonably objects (other than any prospectus supplement relating to the offering of Shelf Securities other than the Common Units). To furnish to the Manager a copy of each proposed free writing prospectus to be prepared by or on behalf of, used by, or referred to by the Company and not to use or refer to any proposed free writing prospectus to which the Manager reasonably objects.

(k) To use its commercially reasonable efforts to cause the Units to be listed for trading on the NYSE and to maintain such listing.

(l) Upon commencement of the offering of the Units under this Agreement (and upon the recommencement of the offering of the Units under this Agreement following the termination of a suspension of sales hereunder), and each time that (i) each Registration Statement or the Prospectus is amended or supplemented (other than a prospectus supplement relating solely to the offering of Shelf Securities other than the Units) or (ii) there is filed with the Commission any document incorporated by reference into the Prospectus (other than a Current Report on Form 8-K, unless the Manager shall otherwise reasonably request) (such commencement date (and any such recommencement date, if applicable) and each such date referred to in (i) and (ii) above, a “Representation Date”), to furnish or cause to be furnished to the Manager forthwith a certificate dated and delivered as of such date, in form reasonably satisfactory to the Manager, to the effect that the statements contained in the certificate referred to in Section 5(b) of this Agreement are true and correct at the time of such commencement, recommencement, amendment, supplement or filing, as the case may be, as though made at and as of such time modified as necessary to relate to each Registration Statement and the Prospectus as amended and supplemented to the time of delivery of such certificate. The requirement to deliver a certificate under this Section 6(l) shall be automatically waived upon notice by the Company to the Managers that the Company temporarily wishes to suspend all sales under this Agreement (the “Suspension Period”). Notwithstanding the foregoing, if the Company subsequently decides to commence the sale of Units under this Agreement following a Suspension Period and the Company has not provided the Manager with a certificate under this Section 6(l), then before the Manager sells any Units, the Company shall provide the Manager with a certificate required under this Section 6(l).

(m) On each Representation Date, the Company shall cause to be furnished to the Manager, dated as of such date, in form and substance satisfactory to the Manager, the written opinion and negative assurance letter of Kirkland & Ellis LLP, outside counsel for the Company.

(n) On each Representation Date, Davis Polk & Wardwell LLP, counsel to the Manager, shall furnish to the Manager a written opinion and negative assurance letter, dated as of such date in form and substance reasonably satisfactory to the Manager.

With respect to Sections ‎6(m) and ‎6(n) above, in lieu of delivering such an opinion and negative assurance letter for dates subsequent to the commencement of the offering of the Units under this Agreement such counsel may furnish the Manager with a letter (a “Reliance Letter”) to the effect that the Manager may rely on a prior opinion and negative assurance letter delivered under Section 6(m) or Section 6(n), as the case may be, to the same extent as if it were dated the date of such letter (except that statements in such prior opinion shall be deemed to relate to each Registration Statement and the Prospectus as amended or supplemented as of such subsequent date).

(o) Upon commencement of the offering of the Units under this Agreement (and upon the recommencement of the offering of the Units under this Agreement following the termination of a suspension of sales hereunder) and each time that (i) each Registration Statement or the Prospectus is amended or supplemented to include additional financial information, (ii) the Company files an annual report on Form 10-K or quarterly report on Form 10-Q, (iii) there is furnished with the Commission by the Company any document which contains financial information, including any earnings release, (iv) there is filed with the Commission any document (other than an annual report on Form 10-K or quarterly report on Form 10-Q) incorporated by reference into the Prospectus which contains additional or amended financial information or (v) on such other dates as may be reasonably requested by the Manager, each of Grant Thornton LLP, Weaver and Tidwell, L.L.P., PricewaterhouseCoopers LLP, Cawley, Gillespie & Associates, Inc. and Netherland, Sewell & Associates, Inc. shall deliver to the Manager the comfort letters described in Section 5.

(p) To comply with the Due Diligence Protocol attached hereto on Schedule I and any other due diligence review or call reasonably requested by the Manager.

(q) To reserve and keep available at all times, free of preemptive rights, Units for the purpose of enabling the Company to satisfy its obligations hereunder.

(t) Not to, or publicly disclose an intention to, sell, offer to sell, contract or agree to sell, hypothecate, pledge, grant any option to sell or otherwise dispose of or agree to dispose of, directly or indirectly, any Common Units or securities convertible into or exchangeable or exercisable for the Common Units or warrants or other rights to purchase the Common Units or any other securities of the Company that are substantially similar to the Common Units or permit the registration under the Securities Act of any Common Units, except for (i) the registration of the Units and the sales through the Manager pursuant to this Agreement, (ii) any Common Units issued by the Company upon the exercise of an option or warrant or the conversion of a security outstanding on the date hereof and referred to in the Prospectus, (iii) any Common Units issued or options to purchase Common Units granted pursuant to existing employee benefit plans of the Company or (iv) any Common Units issued pursuant to any non-employee director stock plan, dividend reinvestment plan or stock purchase plan of the Company, during the Delivery Period, without (A) giving the Manager at least three business days’ prior written notice specifying the nature of the proposed sale and the date of such proposed sale and (B) the Manager suspending activity under this program for such period of time as requested by the Company.

7. Covenants of the Manager. The Manager covenants with the Company not to take any action that would result in the Company being required to file with the Commission under Rule 433(d) a free writing prospectus prepared by or on behalf of the Manager that otherwise would not be required to be filed by the Company thereunder, but for the action of the Manager.

8. Indemnity and Contribution. (a) The Mach Parties each, jointly and severally, agree to indemnify and hold harmless the Manager and each person, if any, who controls the Manager within the meaning of Section 15 of the Securities Act or Section 20(a) of the Exchange Act against any and all losses, liabilities, claims, damages and expenses whatsoever as incurred (including without limitation, reasonable attorneys’ fees and any and all reasonable expenses whatsoever incurred in investigating, preparing or defending against any litigation, commenced or threatened, or any claim whatsoever, and any and all amounts paid in settlement of any claim or litigation, and which are in each case documented by the Manager), joint or several, to which they or any of them may become subject under the Securities Act, the Exchange Act or otherwise, insofar as such losses, liabilities, claims, damages or expenses (or actions in respect thereof) arise out of or are based upon any untrue statement or alleged untrue statement of a material fact contained or incorporated by reference in each Registration Statement, as originally filed or any amendment thereof, each Registration Statement, or any post-effective amendment thereof, or the omission or alleged omission therefrom of a material fact required to be stated therein or necessary to make the statements therein not misleading, or arise out of any untrue statement or alleged untrue statement of a material fact included in the Prospectus, or in any supplement thereto or amendment thereof, the Prospectus Supplement (including any Interim Prospectus Supplement), the General Disclosure Package, or any free writing prospectus that the Company has filed, or is required to file, pursuant to Rule 433(d) under the Securities Act, or arise out of or are based upon the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein, in light of the circumstances under which they were made, not misleading; provided, however, that the Mach Parties will not be liable in any such case to the extent that any such loss, liability, claim, damage or expense arises out of or is based upon any such untrue statement or alleged untrue statement or omission or alleged omission made in each Registration Statement, as originally filed or any amendment thereof, each Registration Statement, or any post-effective amendment thereof, the Prospectus, the Prospectus Supplement (including any Interim Prospectus Supplement), the General Disclosure Package, or any free writing prospectus that the Company has filed, or is required to file, pursuant to Rule 433(d) under the Securities Act, in reliance upon and in conformity with written information furnished to the Mach Parties by or on behalf of the Manager through expressly for use therein.

(b) The Manager agrees to indemnify and hold harmless the Mach Parties, each of the directors of the Mach Parties, each of the officers of the Mach Parties who shall have signed the Registration Statement, and each other person, if any, who controls the Mach Parties within the meaning of Section 15 of the Securities Act or Section 20(a) of the Exchange Act, against any losses, liabilities, claims, damages and expenses whatsoever as incurred (including without limitation, reasonable attorneys’ fees and any and all reasonable expenses whatsoever incurred in investigating, preparing or defending against any litigation, commenced or threatened, or any claim whatsoever, and any and all amounts paid in settlement of any claim or litigation), joint or several, to which they or any of them may become subject under the Securities Act, the Exchange Act or otherwise, insofar as such losses, liabilities, claims, damages or expenses (or actions in respect thereof) arise out of or are based upon any untrue statement or alleged untrue statement of a material fact contained or incorporated by reference in each Registration Statement, as originally filed or any amendment thereof, each Registration Statement, or any post-effective amendment thereof, or the omission or alleged omission therefrom of a material fact required to be stated therein or necessary to make the statements therein not misleading, or arise out of any untrue statement or alleged untrue statement of a material fact included in the Prospectus, or in any supplement thereto or amendment thereof, the Prospectus Supplement (including any Interim Prospectus Supplement), the General Disclosure Package, or any free writing prospectus that the Company has filed, or is required to file, pursuant to Rule 433(d) under the Securities Act, or arise out of or are based upon the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein, in light of the circumstances under which they were made, not misleading, in each case to the extent, but only to the extent, that any such loss, liability, claim, damage or expense arises out of or is based upon any such untrue statement or alleged untrue statement or omission or alleged omission made therein in reliance upon and in conformity with written information furnished to the Company by or on behalf of the Manager expressly for use therein.

(c) Promptly after receipt by an indemnified party under Section 8(a) or 8(b) of notice of the commencement of any action, such indemnified party shall, if a claim in respect thereof is to be made against the indemnifying party under such Section, notify each party against whom indemnification is to be sought in writing of the commencement thereof (but the failure so to notify an indemnifying party shall not relieve it from any liability which it may have under this Section 8). In case any such action is brought against any indemnified party, and it notifies an indemnifying party of the commencement thereof, the indemnifying party will be entitled to participate therein, and jointly with any other indemnifying party similarly notified, to the extent it may elect by written notice delivered to the indemnified party promptly after receiving the aforesaid notice from such indemnified party, to assume the defense thereof with counsel reasonably satisfactory to such indemnified party. Notwithstanding the foregoing, the indemnified party or parties shall have the right to employ its or their own counsel in any such case, but the fees and expenses of such counsel shall be at the expense of such indemnified party or parties unless (i) the employment of such counsel shall have been authorized in writing by one of the indemnifying parties in connection with the defense of such action, (ii) the indemnifying parties shall not have employed counsel to have charge of the defense of such action within a reasonable time after notice of commencement of the action, or (iii) such indemnified party or parties shall have reasonably concluded that there may be defenses available to it or them which are different from or additional to those available to one or all of the indemnifying parties (in which case the indemnifying parties shall not have the right to direct the defense of such action on behalf of the indemnified party or parties), in any of which events such fees and expenses shall be borne by the indemnifying parties. In no event shall the indemnifying parties be liable for fees and expenses of more than one counsel (in addition to any local counsel) separate from their own counsel for all indemnified parties in connection with any one action or separate but similar or related actions in the same jurisdiction arising out of the same general allegations or circumstances, which counsel, in the event of indemnified parties under Section 8(a), shall be selected by the Manager. The indemnifying party shall not be liable for any settlement of any proceeding effected without its written consent, but if settled with such consent or if there is a final judgment for the plaintiff, the indemnifying party agrees to indemnify the indemnified party from and against any loss or liability by reason of such settlement or judgment. Notwithstanding the foregoing sentence, if at any time an indemnified party shall have requested an indemnifying party to reimburse the indemnified party for fees and expenses of counsel as contemplated by the third and fourth sentences of this paragraph, the indemnifying party agrees that it shall be liable for any settlement of any proceeding effected without its written consent if (i) such settlement is entered into more than 30 days after receipt by such indemnifying party or the aforesaid request and (ii) such indemnifying party shall not have reimbursed the indemnified party in accordance with such request prior to the date of such settlement. No indemnifying party shall, without the written consent of the indemnified party, effect the settlement or compromise of, or consent to the entry of any judgment with respect to, any pending or threatened action or claim in respect of which indemnification or contribution may be sought hereunder (whether or not the indemnified party is an actual or potential party to such action or claim) unless such settlement, compromise or judgment (i) includes an unconditional release of the indemnified party from all liability arising out of such action or claim and (ii) does not include a statement as to or an admission of fault, culpability or a failure to act, by or on behalf of any indemnified party.

(d) If the indemnification provided for in this Section 8 is unavailable to or insufficient to hold harmless an indemnified party under Section 8(a) or 8(b) in respect of any losses, liabilities, claims, damages or expenses (or actions in respect thereof) referred to therein, then each indemnifying party shall contribute to the amount paid or payable by such indemnified party as a result of such losses, liabilities, claims, damages or expenses (or actions in respect thereof) in such proportion as is appropriate to reflect the relative benefits received by the Mach Parties on the one hand and the Manager on the other from the offering of the Units. If, however, the allocation provided by the immediately preceding sentence is not permitted by applicable law, then each indemnifying party shall contribute to such amount paid or payable by such indemnified party in such proportion as is appropriate to reflect not only such relative benefits but also the relative fault of the Mach Parties on the one hand and the Manager on the other in connection with the statements or omissions which resulted in such losses, liabilities, claims, damages or expenses (or actions in respect thereof), as well as any other relevant equitable considerations. The relative benefits received by the Mach Parties on the one hand and the Manager on the other from the offering of the Units shall be deemed to be in the same proportion as the total net proceeds from the offering (before deducting expenses) received by the Mach Parties bear to the total underwriting discounts and commissions received by the Manager. The relative fault shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information supplied by the Company on the one hand or the Manager on the other and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. The Mach Parties and the Manager agree that it would not be just and equitable if contributions pursuant to this Section 8(d) were determined by pro rata allocation (even if the Manager was treated as one entity for such purpose) or by any other method of allocation which does not take account of the equitable considerations referred to above in this Section 8(d). The amount paid or payable by an indemnified party as a result of the losses, liabilities, claims, damages or expenses (or actions in respect thereof) referred to above in this Section 8(d) shall be deemed to include any legal or other expenses reasonably incurred by such indemnified party in connection with investigating or defending any such action or claim. Notwithstanding the provisions of this Section 8(d), the Manager shall not be required to contribute any amount in excess of the amount by which the total price at which the Units distributed to the public were offered to the public exceeds the amount of any damages which such Manager has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. The Manager’s obligations in this Section 8(d) to contribute are several in proportion to their respective underwriting obligations and not joint.

(e) The obligations of the parties to this Agreement contained in this Section 8 are not exclusive and shall not limit any rights or remedies which may otherwise be available to any indemnified party at law or in equity.

9. Effectiveness. This Agreement shall become effective upon the execution and delivery hereof by the parties hereto.

10. Termination. (a) The Company shall have the right, by giving written notice as hereinafter specified, to terminate this Agreement in its sole discretion at any time. Any such termination shall be without liability of any party to any other party, except that (i) with respect to any pending sale through the Manager for the Company, the obligations of the Company, including, but not limited to, its obligations under Section 4 above, shall remain in full force and effect notwithstanding such termination; and (ii) the provisions of Section 1 and Section 8 of this Agreement shall remain in full force and effect notwithstanding such termination.

(b) The Manager shall have the right, by giving written notice as hereinafter specified, to terminate this Agreement in its sole discretion at any time. Any such termination shall be without liability of any party to any other party except that (i) with respect to any pending sale through the Manager for the Company, the obligations of the Company, including, but not limited to, its obligations under Section 4 above, shall remain in full force and effect notwithstanding such termination; and (ii) the provisions of Section 1 and Section 8 of this Agreement shall remain in full force and effect notwithstanding such termination.
