3. Sale and Delivery of the Offered Securities. On the basis of the representations, warranties and agreements and subject to the terms and conditions set forth herein, the Partnership Parties and the Manager agree that the Partnership may from time to time seek to sell the Offered Securities through the Manager, acting as sales agent, or directly to the Manager acting as principal, as follows:

(a) The Partnership may submit to the Manager its orders (including any price, time or size limits or other customary parameters and conditions) to sell the Offered Securities on any Trading Day (as defined below). If the Manager agrees to the terms of such proposed transaction or if the Partnership and the Manager mutually agree to modified terms for such proposed transaction, then the Manager shall promptly send to the Partnership by the means set forth under Section 10 a Transaction Notice substantially in the form of Schedule B hereto, confirming the agreed terms of such proposed transaction. If the Partnership wishes such proposed transaction to become a binding agreement between it and the Manager, the Partnership shall promptly indicate its acceptance thereof by countersigning and returning such Transaction Notice to the Manager with a written acceptance of such Transaction Notice by the means set forth under Section 10 hereof or by sending an email confirming acceptance of such Transaction Notice (each, a “Time of Acceptance”); provided, that following such email confirming acceptance, the Partnership will also be obligated to promptly return the countersigned Transaction Notice to the Manager by the means set forth in Section 10 hereof for the parties’ records. The terms reflected in a Transaction Notice shall become binding on the Manager and the Partnership, subject to the terms and conditions of this Agreement, only if accepted by the Partnership no later than the times, specified in such Transaction Notice. Each Transaction Notice shall specify, among other things, the following:

(i) the Trading Day(s) on which the Offered Securities subject to such transaction are intended to be sold (each, a “Purchase Date”);

(ii) the maximum number of Offered Securities that the Partnership intends to sell on, or over the course of, such Purchase Date(s); provided that the number of Offered Securities sold on each such Purchase Date shall be no more than 15% of the average daily trading volume in the common units for the 30 Trading Days preceding the date of delivery of the Transaction Notice or as otherwise agreed between the Partnership and the Manager; and

(iii) the lowest price, if any, at which the Partnership is willing to sell the Offered Securities on each such Purchase Date or a formula pursuant to which such lowest price shall be determined (each, a “Floor Price”).

As used herein, “Trading Day” shall mean any trading day on the NYSE.

(b) Subject to the terms and conditions hereof, the Manager shall use its reasonable efforts to sell the Offered Securities with respect to which the Manager has agreed to act as sales agent under the applicable Transaction Notice. The Partnership acknowledges and agrees that (A) there can be no assurance that the Manager will be successful in selling the Offered Securities, (B) the Manager will incur no liability or obligation to the Partnership or any other person or entity if it does not sell the Offered Securities for any reason other than a failure by the Manager to use its reasonable efforts consistent with its normal trading and sales practices and applicable law and regulations to sell such Offered Securities and (C) the Manager shall be under no obligation to purchase the Offered Securities on a principal basis pursuant to this Agreement, except as otherwise specifically agreed by the Manager and the Partnership under a Terms Agreement substantially in the form of Schedule C hereto.

(c) The Partnership shall not authorize the issuance and sale of, and the Manager shall not sell as sales agent, any Offered Securities at a price lower than the Floor Price therefor designated from time to time by the Partnership pursuant to the applicable Transaction Notice. In addition, the Partnership or the Manager may, upon notice to the other party hereto by telephone (confirmed promptly by email or facsimile), suspend an offering of the Offered Securities with respect to which the Manager is acting as sales agent; provided, however, that such suspension or termination shall not affect or impair the parties’ respective obligations with respect to the Offered Securities sold hereunder prior to the giving of such notice.

(d) If either party has reason to believe that the exemptive provisions set forth in Rule 101(c)(1) of Regulation M under the Exchange Act are not satisfied with respect to the Partnership or the Offered Securities, it shall promptly notify the other party and sales of the Offered Securities under the Distribution Agreements, any Transaction Notice and any Terms Agreement shall be suspended until that or other exemptive provisions have been satisfied in the judgment of each party.

(e) The compensation to the Manager for sales of the Offered Securities with respect to which the Manager acts as sales agent hereunder shall be equal to 1.50% of the gross offering proceeds of the Offered Securities sold pursuant to this Agreement. The Partnership may sell the Offered Securities to the Manager as principal at a price agreed upon at the relevant Applicable Time. Any compensation or commission due and payable to the Manager as principal will be at a price agreed upon at the relevant Applicable Time. Any compensation or commission due and payable to the Manager hereunder with respect to any sale of the Offered Securities during a calendar month shall be paid by the Partnership to the Manager in arrears on the first Trading Day of the following calendar month, by wire or internal bank transfer of same day funds to an account designated by the Manager.

(f) Settlement for sales of the Offered Securities pursuant to this Agreement will occur on the third Trading Day (or such earlier day as is industry practice for regular-way trading) following the date on which such sales are made (each such day, a “Settlement Date”). On each Settlement Date, the Offered Securities sold through or to the Manager for settlement on such date shall be issued and delivered by the Partnership to the Manager against payment of the gross proceeds from the sale of such Offered Securities. Settlement for all such Offered Securities shall be effected by free delivery of the Offered Securities by the Partnership or its transfer agent to the Manager’s or its designee’s accounts (provided that the Manager shall have given the Partnership notice of such designee prior to the Settlement Date) at The Depository Trust Company through its Deposit and Withdrawal at Custodian System or by such other means of delivery as may be mutually agreed upon by the parties hereto which in all cases shall be freely tradable, transferable, registered the Offered Securities in good deliverable form, in return for payments in same day funds delivered to the account designated by the Partnership. If the Partnership, or its transfer agent (if applicable) shall default on its obligation to deliver the Offered Securities on any Settlement Date, the Partnership shall (A) hold the Manager harmless against any loss, claim, damage, or expense (including reasonable legal fees and expenses), as incurred, arising out of or in connection with such default by the Partnership and (B) pay the Manager any commission, discount or other compensation to which it would otherwise be entitled absent such default.

(g) If acting as sales agent hereunder, the Manager shall provide written confirmation (which may be by facsimile or email) to the Partnership following the close of trading on the NYSE each day in which the Offered Securities are sold under this Agreement and the applicable Transaction Notice, setting forth (A) the amount of Offered Securities sold on such day and the gross offering proceeds received from such sale and (B) the commission payable by the Partnership to the Manager with respect to such sales.

(h) The Manager hereby covenants and agrees not to make any sales of the Offered Securities on behalf of the Partnership, pursuant to this Section 3(a), other than (A) by means of ordinary brokers’ transactions that qualify for delivery of a Prospectus in accordance with Rule 153 under the Act (such transactions are hereinafter referred to as “At the Market Offerings”) and (B) such other sales of the Offered Securities on behalf of the Partnership in its capacity as agent of the Partnership as shall be agreed by the Partnership and the Manager under the applicable Transaction Notice. The Partnership acknowledges and agrees that in the event a sale of the Offered Securities on behalf of the Partnership would constitute the sale of a “block” under Rule 10b-18(a)(5) under the Exchange Act or a “distribution” within the meaning of Rule 100 of Regulation M under the Exchange Act or the Manager reasonably believes it may be deemed an “underwriter” under the Act in a transaction that is not an At the Market Offering, the Partnership will provide to the Manager, at the Manager’s request and upon reasonable advance notice to the Partnership, on or prior to any Settlement Date, the opinions of counsel, accountants’ letters and officers’ certificates pursuant to Section 5 hereof that the Partnership would be required to provide to the Manager in connection with a sale of the Offered Securities pursuant to a Terms Agreement, each dated such Settlement Date, and such other documents and information as the Manager shall reasonably request.

(i) At each Representation Date, the Partnership shall be deemed to have affirmed each representation, warranty, covenant and other agreement contained in this Agreement. Any obligation of the Manager to use its reasonable efforts to sell the Offered Securities on behalf of the Partnership as sales agent under any

Transaction Notice or to act as principal pursuant to a Terms Agreement shall be subject to the continuing accuracy of the representations and warranties of the Partnership herein, to the performance by the Partnership of its obligations hereunder and to the continuing satisfaction of the additional conditions specified in Section 5 of this Agreement.

(j) If the Partnership wishes to issue and sell the Offered Securities other than as set forth in Section 3 of this Agreement (each, a “Placement”), it will notify the Manager of the proposed terms of such Placement. If the Manager, acting as principal, wishes to accept such proposed terms (which it may decline to do for any reason in its sole discretion) or, following discussions with the Partnership, wishes to accept amended terms, the Manager and the Partnership will enter into a Terms Agreement setting forth the terms of such Placement.

(k) The terms set forth in a Terms Agreement will not be binding on the Partnership or the Manager unless and until the Partnership and the Manager have each executed such Terms Agreement, accepting all of the terms of such Terms Agreement. In the event of a conflict between the terms of this Agreement and the terms of a Terms Agreement, the terms of such Terms Agreement will control.

(l) Under no circumstances shall the aggregate gross sales proceeds of the Offered Securities sold pursuant to the Distribution Agreements and any Terms Agreement exceed the Maximum Amount.

(m) Each sale of the Offered Securities to the Manager shall be made in accordance with the terms of this Agreement and, if applicable, a Terms Agreement, which will provide for the sale of such Offered Securities to, and the purchase thereof by, the Manager. A Terms Agreement may also specify certain provisions relating to the reoffering of such Offered Securities by the Manager. The commitment of the Manager to purchase the Offered Securities pursuant to any Terms Agreement shall be deemed to have been made on the basis of the representations and warranties of the Partnership contained herein and in any Terms Agreement and shall be subject to the terms and conditions set forth herein and in any Terms Agreement. Each Terms Agreement shall specify the number of the Offered Securities to be purchased by the Manager pursuant thereto, the price to be paid to the Partnership for such Offered Securities, any provisions relating to rights of, and default by, underwriters acting together with the Manager in the reoffering of the Offered Securities, and the time and date (each such time and date being referred to herein as a “Principal Settlement Date”) and place of delivery of and payment for such Offered Securities. Such Terms Agreement shall also specify any requirements for opinions of counsel, accountants’ letters and officers’ certificates pursuant to Section 5 of this Agreement and any other information or documents required by the Manager.

(n) Subject to the limitations set forth herein and as may be mutually agreed upon by the Partnership and the Manager, sales pursuant to this Agreement, any Transaction Notice and any Terms Agreement may not be requested by the Partnership and need not be made by the Manager except during the period that begins after the filing of a Quarterly Report on Form 10-Q or an Annual Report on Form 10-K as of and within the period required by the Exchange Act (each such date, a “Filing Date”) and ends, for all periods, fifteen days prior to the end of the quarter in which the applicable Filing Date occurs. Notwithstanding the foregoing, without the prior written consent of each of the Partnership and the Manager, no sales of the Offered Securities shall take place, and the Partnership shall not request the sale of any of the Offered Securities that would be sold, and the Manager shall not be obligated to sell, during any period in which the Partnership is or could be deemed to be, in possession of material non-public information.

4. Certain Agreements of the Partnership. The Partnership agrees with the Manager that:

(a) Filing of Amendments; Response to Commission Requests. The Partnership will promptly advise the Manager of any proposal to amend or supplement (including by means of documents incorporated by reference) the Registration Statement, the Disclosure Package, the Prospectus or any Permitted Free Writing Prospectus (as defined below) at any time and will offer the Manager and its counsel a reasonable opportunity to comment on any such proposed amendment or supplement, and will file no such amendment or supplement to which the Manager shall have reasonably objected in writing. The Partnership will prepare and file with the Commission, promptly upon the Manager’s request, any amendments or supplements to the Registration Statement, the Disclosure Package, the Prospectus or any Permitted Free Writing Prospectus (as defined below) that, in the Manager’s reasonable opinion, may be necessary or advisable in connection with the offering of the Offered Securities by the Manager; and to cause each amendment or supplement to the Prospectus or any Permitted Free Writing Prospectus (as defined below) to be filed with the Commission as required pursuant to the applicable paragraph of Rule 424(b) of the Act. The Partnership will also advise the Manager promptly of (i) the filing of any such amendment or supplement,

(ii) any request by the Commission or its staff for any amendments or supplements to the Registration Statement, the Disclosure Package, the Prospectus or any Permitted Free Writing Prospectus (as defined below) or for additional information with respect thereto, (iii) the institution by the Commission of any stop order proceedings in respect of the Registration Statement or the notice or threatening of any proceeding for that purpose, and (iv) the receipt by the Partnership of any notification with respect to the suspension of the qualification of the Offered Securities in any jurisdiction or the institution or threatening of any proceedings for such purpose. The Partnership will use its best efforts to prevent the issuance of any such stop order or the suspension of any such qualification and, if issued, to obtain as soon as possible the withdrawal thereof.

(b) Continued Compliance with Securities Laws. If, at any time when a prospectus relating to the Offered Securities is required to be delivered under the Act (whether physically, deemed to be delivered pursuant to Rule 153 or through compliance with Rule 172 under the Act or any similar rule), any event occurs as a result of which the Prospectus as then amended or supplemented would include an untrue statement of a material fact or omit to state any material fact necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading, or if it is necessary at any time to amend the Registration Statement or supplement the Prospectus to comply with the Act, the Partnership will promptly notify the Manager of such event and promptly notify the Manager to suspend solicitation of purchases of the Offered Securities and forthwith upon receipt of such notice, the Manager will suspend its solicitation of purchases of the Offered Securities and will cease using the Prospectus; and if the Partnership shall decide to amend or supplement the Registration Statement, the Disclosure Package or the Prospectus, it will promptly advise the Manager by telephone (with confirmation in writing), will promptly prepare and file with the Commission an amendment or supplement to the Registration Statement, the Disclosure Package or the Prospectus which will correct such statement or omission or effect such compliance and will advise the Manager when the Manager is free to resume such solicitation. Neither the Manager’s consent to, nor the Manager’s delivery of, any such amendment or supplement shall constitute a waiver of any of the conditions set forth in Section 5 hereof.

(c) Exchange Act Reports. The Partnership will file promptly all reports and documents and any preliminary or definitive proxy or information statement required to be filed by the Partnership with the Commission pursuant to Sections 13(a), 13(c), 14 or 15(d) of the Exchange Act for so long as a prospectus is required to be delivered under the Act (whether physically, deemed to be delivered pursuant to Rule 153 or through compliance with Rule 172 under the Act or any similar rule). The Partnership will promptly advise the Manager if the Partnership failed to file any report, document or statement within the time period prescribed in the Exchange Act. The Partnership will provide the Manager, for its review and comment, with a copy of such reports, documents and statements to be filed by the Partnership pursuant to Section 13(a), 13(c), 14 or 15(d) of the Exchange Act during such period a reasonable amount of time prior to any proposed filing, and will not file such report, statement or document to which the Manager shall have reasonably objected in writing.

(d) Registration Statement. If at any time when the Offered Securities remain unsold by the Manager the Partnership receives from the Commission a notice pursuant to Rule 401(g)(2) under the Act or otherwise ceases to be eligible to use the automatic shelf registration statement form, the Partnership will (i) promptly notify the Manager, (ii) promptly file a new registration statement or post-effective amendment on the proper form relating to the Offered Securities, in a form reasonably satisfactory to the Manager, (iii) use its best efforts to cause such registration statement or post-effective amendment to be declared effective as soon as practicable (if such filing is not otherwise effective immediately pursuant to Rule 462 under the Act) and (iv) promptly notify the Manager of such effectiveness. The Partnership will take all other action necessary or appropriate to permit the public offering and sale of the Offered Securities to continue as contemplated in the Registration Statement that was the subject of the notice under Rule 401(g)(2) under the Act or for which the Partnership has otherwise become ineligible. References herein to the “Registration Statement” will include such new registration statement or post-effective amendment, as the case may be.

(e) New Shelf. If immediately prior to the third anniversary (the “Renewal Deadline”) of the initial effective date of the Registration Statement, any of the Offered Securities remain unsold by the Manager, the Partnership will, prior to the Renewal Deadline file, if it has not already done so and is eligible to do so, a new automatic shelf registration statement relating to the Offered Securities, in a form reasonably satisfactory to the Manager. If the Partnership is not eligible to file an automatic shelf registration statement, the Partnership will, prior to the Renewal Deadline, if it has not already done so, file a new shelf registration statement relating to the Offered Securities, in a form reasonably satisfactory to the Manager, and will use its best efforts to cause such registration statement to be declared effective within 180 days after the Renewal Deadline. The Partnership will take all other

action necessary or appropriate to permit the public offering and sale of the Offered Securities to continue as contemplated in the expired registration statement. References herein to the “Registration Statement” will include such new automatic shelf registration statement or such new shelf registration statement, as the case may be.

(f) Rule 158.

(g) Furnishing of Prospectuses. The Partnership will furnish to the Manager, without charge, as soon as practicable after the Registration Statement becomes effective and thereafter upon request, as many copies of the Disclosure Package or Prospectus (or of the Disclosure Package or Prospectus as amended or supplemented if the Partnership will have made any amendments or supplements thereto after the effective date of the Registration Statement) and each Permitted Free Writing Prospectus as the Manager may request; in case the Manager is required to deliver (whether physically, deemed to be delivered pursuant to Rule 153 or through compliance with Rule 172 under the Act or any similar rule), in connection with the sale of the Offered Securities, a Prospectus after the nine-month period referred to in Section 10(a)(3) of the Act, or after the time a post-effective amendment to the Registration Statement is required pursuant to Item 512(a) of Regulation S-K under the Act, the Partnership will prepare, at its expense, promptly upon request such amendment or amendments to the Registration Statement and the Disclosure Package or Prospectus as may be necessary to permit compliance with the requirements of Section 10(a)(3) of the Act or Item 512(a) of Regulation S-K under the Act, as the case may be.

(h) Blue Sky Qualifications. The Partnership will arrange for the qualification of the Offered Securities for offering and sale under the Offered Securities or blue sky laws of such states or other jurisdictions as the Manager designates and will maintain such qualifications in effect so long as required for the distribution of the Offered Securities; provided, however, that the Partnership will not be required to qualify as a foreign corporation or to consent to the service of process under the laws of any such jurisdiction (except service of process with respect to the offering and sale of the Offered Securities). The Partnership will promptly advise the Manager of the receipt by the Partnership of any notification with respect to the suspension of the qualification of the Offered Securities for offer or sale in any such jurisdiction or the initiation or threatening of any proceeding for such purpose.

(i) Reporting Requirements. During the period of five years after the date of this Agreement, the Partnership will furnish to the Manager, as soon as practicable after the end of each fiscal year, a copy of its annual report to equity holders for such year; and the Partnership will furnish to the Manager (i) as soon as available, a copy of each report and any definitive proxy statement of the Partnership filed with the Commission under the Exchange Act or mailed to equity holders, and (ii) from time to time, such other information concerning the Partnership as the Manager may reasonably request.

The Partnership Parties will each, jointly and not severally, indemnify and hold harmless the Manager, its partners, members, directors, officers, employees, managers, affiliates and each person, if any, who controls any Agent within the meaning of Section 15 of the Act or Section 20 of the Exchange Act (each, an “Indemnified Party”), against any and all losses, claims, damages or liabilities, joint or several, to which such Indemnified Party may become subject, under the Act, the Exchange Act, other federal or state statutory law or regulation or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon any untrue statement or alleged untrue statement of any material fact contained in any part of the Registration Statement at any time, any part of the Disclosure Package, any Prospectus as of any time, any Issuer Free Writing Prospectus, or any “road show” (as defined in Rule 433 under the Act) not constituting an Issuer Free Writing Prospectus (a “Non-Prospectus Road Show”), or any amendment or supplement thereto, or any related preliminary prospectus or preliminary prospectus supplement 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 not misleading, and will reimburse each Indemnified Party for any legal or other expenses reasonably incurred by such Indemnified Party in connection with investigating or defending against any loss, claim, damage, liability, action, litigation, investigation or proceeding whatsoever (whether or not such Indemnified Party is a party thereto), whether threatened or commenced, and in connection with the enforcement of this provision with respect to any of the above as such expenses are incurred; provided, however, that the Partnership will not be liable in any such case to the extent that any such loss, claim, damage or liability arises out of or is based upon an untrue statement or alleged untrue statement in or omission or alleged omission from any of such documents in reliance upon and in conformity with written information furnished to the Partnership by the Manager specifically for use therein, it being understood and agreed that the only such information furnished by the Manager consists of the information expressly described as such in subsection (b) below.

(b) Indemnification of Partnership. The Manager will indemnify and hold harmless the Partnership, each of its directors who signs a Registration Statement and each of its officers and each person, if any, who controls the Partnership within the meaning of Section 15 of the Act or Section 20 of the Exchange Act (each, a “Manager Indemnified Party”), against any losses, claims, damages or liabilities to which such Manager Indemnified Party may become subject, under the Act, the Exchange Act, other federal or state statutory law or regulation or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon any untrue statement or alleged untrue statement of any material fact contained in any part of the Registration Statement at any time, any part of the Disclosure Package, any Prospectus as of any time, or any Issuer Free Writing Prospectus or any Non-Prospectus Road Show or any amendment or supplement thereto, or any related preliminary prospectus or preliminary prospectus supplement or arise out of or are based upon the omission or the alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, in each case to the extent, but only to the extent, that such untrue statement or alleged untrue statement or omission or alleged omission was made in reliance upon and in conformity with written information furnished to the Partnership by the Manager specifically for use therein, and will reimburse any legal or other expenses reasonably incurred by such Manager Indemnified Party in connection with investigating or defending against any such loss, claim, damage, liability, action, litigation, investigation or proceeding whatsoever (whether or not such Manager Indemnified Party is a party thereto), whether threatened or commenced, based upon any such untrue statement or omission, or any such alleged untrue statement or omission as such expenses are incurred, it being understood and agreed that the only such information furnished by the Manager consists of the following information in the Prospectus furnished. The Partnership and the Manager acknowledge that no information has been furnished to the Partnership by the Manager for use in the Disclosure Package or any Non-Prospectus Road Show other than the names of the Manager and the fact that they are participating in the offering as sales Manager hereunder.

(c) Actions against Parties; Notification. Promptly after receipt by an indemnified party under this Section of notice of the commencement of any action, such indemnified party will, if a claim in respect thereof is to be made against the indemnifying party under subsection (a) or (b) above, notify the indemnifying party of the commencement thereof; provided that the failure to notify the indemnifying party shall not relieve it from any liability that it may have under subsection (a) or (b) above except to the extent that it has been materially prejudiced (through the forfeiture of substantive rights or defenses) by such failure; and provided further that the failure to notify the indemnifying party shall not relieve it from any liability that it may have to an indemnified party otherwise than under subsection (a) or (b) above. In case any such action is brought against any indemnified party and it notifies the indemnifying party of the commencement thereof, the indemnifying party will be entitled to participate therein and, to the extent that it may wish, jointly with any other indemnifying party similarly notified, to assume the defense thereof, with counsel satisfactory to such indemnified party (who shall not, except with the consent of the indemnified party, be counsel to the indemnifying party), and after notice from the indemnifying party to such indemnified party of its election so to assume the defense thereof, the indemnifying party will not be liable to such indemnified party under this Section for any legal or other expenses subsequently incurred by such indemnified party in connection with the defense thereof other than reasonable costs of investigation; provided, however, if such indemnified party shall have been advised by counsel that there are one or more defenses available to it that are in conflict with those available to the indemnifying party (in which case the indemnifying party shall not have the right to direct the defense of such action on behalf of the indemnified party), the reasonable fees and expenses of such indemnified party’s counsel shall be borne by the indemnifying party. In no event shall the indemnifying party be liable for the fees and expenses of more than one counsel (together with appropriate local counsel) at any time for any indemnified party in connection with any one action or separate but substantially similar or related actions arising in the same jurisdiction out of the same general allegations or circumstances. No indemnifying party shall, without the prior written consent of the indemnified party, effect any settlement of any pending or threatened action in respect of which any indemnified party is or could have been a party and indemnity could have been sought hereunder by such indemnified party unless such settlement (i) includes an unconditional release of such indemnified party from all liability on any claims that are the subject matter of such action 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 an indemnified party.

(d) Contribution. If the indemnification provided for in this Section is unavailable or insufficient to hold harmless an indemnified party under subsection (a) or (b) above, then each indemnifying party shall contribute to the amount paid or payable by such indemnified party as a result of the losses, claims, damages or liabilities referred to in subsection (a) or (b) above (i) in such proportion as is appropriate to reflect the relative benefits

received by the Partnership Parties on the one hand and the Manager on the other from the offering of the Offered Securities or (ii) if the allocation provided by clause (i) above is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to in clause (i) above but also the relative fault of the Partnership Parties on the one hand and the Manager on the other in connection with the statements or omissions which resulted in such losses, claims, damages or liabilities as well as any other relevant equitable considerations. The relative benefits received by the Partnership Parties on the one hand and the Manager on the other shall be deemed to be in the same proportion as the total net proceeds from the offering (before deducting expenses) received by the Partnership Parties bear to the total commissions received by the Manager from the Partnership under this Agreement. 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 Partnership Parties or the Manager and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such untrue statement or omission. The amount paid by an indemnified party as a result of the losses, claims, damages or liabilities referred to in the first sentence of this subsection (d) shall be deemed to include any legal or other expenses reasonably incurred by such indemnified party in connection with investigating or defending any action or claim which is the subject of this subsection (d). Notwithstanding the provisions of this subsection (d), Manager shall not be required to contribute any amount in excess of the amount by which the total price at which the Offered Securities sold by it and distributed to the public exceeds the amount of any damages which the 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 Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. The Partnership Parties and the Manager each agree that it would not be just and equitable if contribution pursuant to this Section 6(d) were determined by pro rata allocation or by any other method of allocation which does not take account of the equitable considerations referred to in this Section 6(d).

7. Survival of Certain Representations and Obligations. The respective indemnities, agreements, representations, warranties and other statements of the Partnership Parties or its officers and of the Manager set forth in or made pursuant to this Agreement, will remain in full force and effect regardless of any investigation or statement as to the results thereof, made by or on behalf of the Manager, the Partnership Parties or any of their respective representatives, officers or directors or any controlling person, and will survive delivery of and payment for the Offered Securities. If any Offered Securities have been sold hereunder, the representations and warranties in Section 2 and all obligations under Section 4 shall also remain in effect.

8. Termination.

(a) This Agreement shall terminate with the aggregate sale under the Distribution Agreements of the Maximum Amount, and the Partnership shall have the right, by giving written notice as hereinafter specified, to terminate the provisions of this Agreement and any of the Alternative Distribution Agency Agreements relating to the solicitation of offers to purchase the Offered Securities in its sole discretion at any time. Any such termination shall be without liability of any party to any other party except that (i) if any of the Offered Securities have been sold through the Manager for the Partnership, then Section 4(l) shall remain in full force and effect, (ii) with respect to any pending sale, through the Manager for the Partnership, the obligations of the Partnership, including in respect of compensation of the Manager, shall remain in full force and effect notwithstanding the termination and (iii) the provisions of Section 4(d), 6, 7, 8, 9, 10, 11 and 12 of this Agreement shall remain in full force and effect notwithstanding such termination.

(b) In the case of any sale by the Partnership pursuant to a Terms Agreement, the obligations of the Partnership pursuant to such Terms Agreement and this Agreement may not be terminated by the Partnership without the prior written consent of the Manager.

(c) The Manager shall have the right, by giving written notice as hereinafter specified, to terminate the provisions of this Agreement relating to the solicitation of offers to purchase the Offered Securities in its sole discretion at any time. Any such termination shall be without liability of any party to any other party except that the provisions of Section 4(d), 6, 7, 10, 11 and 12 of this Agreement shall remain in full force and effect notwithstanding such termination.

(d) This Agreement shall remain in full force and effect unless terminated pursuant to Sections 8(a) or (c) above or otherwise by mutual agreement of the parties; provided that any such termination by mutual agreement shall in all cases be deemed to provide that Section 4(d), Section 6 and Section 7 shall remain in full force and effect.

(e) Any termination of this Agreement shall be effective on the date specified in such notice of termination; provided that such termination shall not be effective until the close of business on the date of receipt of such notice by the Manager or the Partnership, as the case may be. If such termination shall occur prior to the Settlement Date for any sale of the Offered Securities, such sale shall settle in accordance with the provisions of Section 3(f) of this Agreement.

9. Research Independence. The Partnership Parties acknowledges that the Manager’s research analysts and research department(s) are required to be independent from its respective investment banking divisions and are subject to certain regulations and internal policies, and that the Manager’s research analysts may hold and make statements or investment recommendations and/or publish research reports with respect to the Partnership and/or the offering that differ from the views of its investment bankers. The Partnership Parties hereby waive and release, to the fullest extent permitted by law, any claims that the Partnership Parties may have against the Manager with respect to any conflict of interest that may arise from the fact that the views expressed by the Manager’s independent research analysts and research department(s) may be different from or inconsistent with the views or advice communicated to the Partnership Parties by the Manager’s investment banking division. The Partnership Parties acknowledge that the Manager is a full service securities firm and as such from time to time, subject to applicable securities laws, may effect transactions for their own accounts or the accounts of its customers and hold long or short positions in debt or equity securities of the companies that may be the subject of the transactions contemplated by this Agreement and any Terms Agreement.

10. Notices. All communications hereunder, and pursuant to any Transaction Notice or under any Terms Agreement will be in writing and mailed, delivered or telecopied and confirmed to the Manager at [NAME OF MANAGER], [ADDRESS], Attention: [●], or, if sent to the Partnership Parties, will be mailed, delivered or telegraphed and confirmed to it at Hi-Crush Partners LP, Hi-Crush GP LLC, ▇▇▇▇▇ ▇▇▇▇▇▇▇▇, ▇▇▇▇▇ ▇▇▇▇, ▇▇▇▇▇▇▇, ▇▇▇▇▇ ▇▇▇▇▇, Attention General Counsel; Facsimile No.: ▇▇▇-▇▇▇-▇▇▇▇.

11. Successors. This Agreement, any Transaction Notice and any Terms Agreement will inure to the benefit of and be binding upon the parties hereto and their respective successors and the officers and directors and controlling persons referred to in Section 6, and no other person will have any right or obligation hereunder.

12. Counterparts. This Agreement, any Transaction Notice and any Terms Agreement may be executed in any number of counterparts, each of which shall be deemed to be an original, but all such counterparts shall together constitute one and the same Agreement.

13. Absence of Fiduciary Relationship. Each of the Partnership Parties acknowledges and agrees that:

(a) No Other Relationship. The Manager has been retained solely to act as sales agent and/or principal in connection with the purchase and sale of the Offered Securities and that no fiduciary, advisory or agency relationship between any Partnership Party and the Manager has been created in respect of any of the transactions contemplated by this Agreement, any Transaction Notice, any Terms Agreement or the Prospectus, irrespective of whether the Manager has advised or is advising any Partnership Party on other matters or any oral representations or assurances previously or subsequently made by the Manager;

(b) Arm’s-Length Negotiations. The Manager is not acting as advisor, expert or otherwise, to any Partnership Entity, including, without limitation, with respect to the determination of the sales price of the Offered Securities. The sales price of the Offered Securities set forth in this Agreement, any Transaction Notice or any Terms Agreement was established by the Partnership following discussions and arm’s-length negotiations with the Manager, and the Partnership is capable of evaluating and understanding and understands and accepts the terms, risks and conditions of the transactions contemplated by this Agreement, any Transaction Notice or any Terms Agreement;

(c) Absence of Obligation to Disclose. The Partnership Parties have been advised that the Manager and its affiliates are engaged in a broad range of transactions which may involve interests that differ from those of the Partnership Parties and that the Manager has no obligation to disclose such interests and transactions to the Partnership by virtue of any fiduciary, advisory or agency relationship; and

(d) Waiver. Each Partnership Party waives, to the fullest extent permitted by law, any claims it may have against the Manager for breach of fiduciary duty or alleged breach of fiduciary duty and agrees that the Manager shall have no liability (whether direct or indirect) to any Partnership Party in respect of such a fiduciary duty claim or to any person asserting a fiduciary duty claim on behalf of or in right of the Partnership Party, including equity holders, employees or creditors of any Partnership Party.

14. Applicable Law. This Agreement and any Terms Agreement shall be governed by, and construed in accordance with, the laws of the State of New York. Each Partnership Party hereby submits to the non-exclusive jurisdiction of the federal and state courts in the Borough of Manhattan in The City of New York in any suit or proceeding arising out of or relating to this Agreement, any Transaction Notice, any Terms Agreement or the transactions contemplated hereby. Each Partnership Party irrevocably and unconditionally waives any objection to the laying of venue of any suit or proceeding arising out of or relating to this Agreement, any Transaction Notice, any Terms Agreement or the transactions contemplated hereby in federal and state courts in the Borough of Manhattan in The City of New York and irrevocably and unconditionally waives and agrees not to plead or claim in any such court that any such suit or proceeding in any such court has been brought in an inconvenient forum.

The Manager and each Partnership Party (on its behalf and, to the extent permitted by applicable law, on behalf of its equity holders and affiliates) waives all right to trial by jury in any action, proceeding or counterclaim (whether based upon contract, tort or otherwise) in any way arising out of or relating to this Agreement, any Transaction Notice and any Terms Agreement.

If the foregoing is in accordance with the Manager’s understanding of our agreement, kindly sign and return to the Partnership one of the counterparts hereof, whereupon it will become a binding agreement between the Partnership Parties and the Manager in accordance with its terms.

TERMS AGREEMENT

[NAME OF UNDERWRITER]

[ADDRESS]

Dear Ladies and Gentlemen:

Hi-Crush Partners LP, a Delaware limited partnership (the “Partnership”), and Hi-Crush GP LLC, a Delaware limited liability company and general partner of the Partnership, proposes, subject to the terms and conditions stated herein and in the Distribution Agency Agreement, dated January 4, 2017 (the “Distribution Agreement”), between the Partnership and [ ] (the “Manager”), to issue and sell to the Manager the Offered Securities specified in the Schedule hereto (the “Purchased Securities”), and solely for the purpose of covering over-allotments, to grant to the Manager the option to purchase the additional securities specified in the Schedule hereto (the “Additional Securities”). Capitalized terms used but not defined herein shall have the meanings ascribed to them in the Distribution Agreement.

The Manager shall have the right to purchase from the Partnership all or a portion of the Additional Securities as may be necessary to cover over-allotments made in connection with the offering of the Purchased Securities, at the same purchase price per share to be paid by the Manager to the Partnership for the Purchased Securities. This option may be exercised by the Manager at any time (but not more than once) on or before the thirtieth day following the date hereof, by written notice to the Partnership. Such notice shall set forth the aggregate number of the Offered Securities of Additional Securities as to which the option is being exercised, and the date and time when the Additional Securities are to be delivered (such date and time being herein referred to as the “Option Settlement Date”); provided, however, that the Option Settlement Date shall not be earlier than the Settlement Date (as set forth in the Schedule hereto) nor earlier than the second business day after the date on which the option shall have been exercised nor later than the fifth business day after the date on which the option shall have been exercised. Payment of the purchase price for the Additional Securities shall be made at the Option Settlement Date in the same manner and at the same office as the payment for the Purchased Securities.

Each of the provisions of the Distribution Agreement not specifically related to the solicitation by the Manager, as Manager of the Partnership, of offers to purchase securities is incorporated herein by reference in its entirety, and shall be deemed to be part of this Terms Agreement to the same extent as if such provisions had been set forth in full herein. Each of the representations, warranties and agreements set forth therein shall be deemed to have been made as of the date of this Terms Agreement and the Settlement Date and any Option Settlement Date.

An amendment to the Registration Statement (as defined in the Distribution Agreement), or a supplement to the Prospectus, as the case may be, relating to the Purchased Securities and the Additional Securities, in the form heretofore delivered to the Manager is now proposed to be filed with the Offered Securities and Exchange Commission.

Subject to the terms and conditions set forth herein and in the Distribution Agreement, which are incorporated herein by reference, the Partnership agrees to issue and sell to the Manager and the latter agrees to purchase from the Partnership the Purchased Securities at the time and place and at the purchase price set forth in the Schedule hereto.

Notwithstanding any provision of this Terms Agreement or any terms agreement to the contrary, the Partnership Parties consent to the Manager trading in the Offered Securities for the Manager’s own account and for the accounts of its respective clients at the same time as sales of the Offered Securities occur pursuant to this Terms Agreement.

If the foregoing is in accordance with your understanding, please sign and return to us a counterpart hereof, whereupon this Terms Agreement, including those provisions of the Distribution Agreement incorporated herein by reference, shall constitute a binding agreement between the Manager and the Partnership.
