(i) Any of the individuals listed as an authorized representative of the Partnership on Schedule B hereto, as such Schedule B may be amended or supplemented by the Partnership from time to time (the “ Authorized Partnership Representatives ”) may submit to any Manager the Partnership’s orders (including any price, time or size limits or other customary parameters or conditions) to sell Units on any Trading Day (as defined herein) substantially in the form attached hereto as Exhibit D , or in a different form and in a different manner as mutually agreed to by the Partnership and such Manager (a “ Transaction Proposal ”); provided, however , that the Partnership will only submit its orders to one of the Managers with respect to any single Trading Day; provided further, however , that in any event the maximum amount of the Units to be sold by such Manager shall not exceed the number of Units available for issuance under the Prospectus and the Registration Statement. If the Partnership delivers a Transaction Proposal to one of the Managers in the form attached hereto as Exhibit D and the proposed terms thereof are acceptable to such Manager, then such Manager shall confirm the terms thereof by countersigning and delivering the Transaction Proposal (which may be by e-mail) to an Authorized Partnership Representative. If the terms of any Transaction Proposal contemplate that Units shall be sold on more than one Trading Day, then the Partnership and the applicable Manager shall mutually agree to such additional terms and conditions as the Partnership, on the one hand, and the applicable Manager, on the other hand, deem necessary in respect of such multiple Trading Days, and such additional terms and conditions shall be binding to the same extent as any other terms contained in the relevant Transaction Proposal.

18

Partnership or any other person or entity if it does not sell Units for any reason other than a failure by such Manager to use its reasonable efforts consistent with its normal trading and sales practices and applicable Laws to sell such Units as required under this Agreement, and (C) no Manager shall be under any obligation to purchase Units on a principal basis pursuant to this Agreement, except as otherwise specifically agreed by such Manager and the Partnership pursuant to a Terms Agreement.

(iii) The Partnership shall not authorize the issuance and sale of, and each Manager shall not sell as sales agent, any Unit at a price lower than the minimum price therefor designated from time to time by the Partnership and notified to such Manager by an Authorized Partnership Representative in writing.

Upon the delivery of a Recommencement Notice by the Partnership to the Managers, the Partnership shall deliver to the Managers the documents, if any, then required by Section 4 on the Recommencement Date and/or thereafter in accordance with the terms of this Agreement as if no Notice of Temporary Suspension had been given; provided, however , that if the Managers were the suspending party, then the Partnership shall not be obligated to provide the documents, if any, then required by Section 4 until such time as the Partnership determines to recommence the offer and sale of Units with respect to Managers subject to such suspension pursuant to this Agreement by delivering a Recommencement Notice to such Managers following receipt of the Manager’s Recommencement Notice.

(iv) Each of the Managers hereby covenants and agrees not to make any sales of the Units on behalf of the Partnership pursuant to this Section 3(a) other than (A) by any method permitted by Law deemed to be an “ at the market ” offering as defined in Rule 415(a)(4) of the Securities Act, including without limitation sales made directly on the Primary Stock Exchange, on any other existing trading market for the Units or to or through a market maker, and (B) such other sales of the Units on behalf of the Partnership in its capacity as sales agent of the Partnership as shall be mutually agreed upon by the Partnership and such Manager.

Such rate of compensation shall not apply when such Manager acts as principal. At each Manager’s election, such compensation shall either be (A) set forth and invoiced in periodic statements from such Manager to the Partnership, with payment to be made by the Partnership promptly after its receipt thereof or (B) deducted by the Manager from the payment of the gross sales proceeds to the Partnership.

If the Partnership, or its transfer agent (if applicable), shall default on its obligation to deliver the Units on any Settlement Date, in addition to and in no way limiting the rights and obligations set forth in Section 7(a) , the Partnership shall (A) indemnify and hold such 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 such Manager any commission, discount or other compensation to which it would otherwise be entitled absent such default. The Authorized Partnership Representatives shall be the contact persons for the Partnership for all matters related to the settlement of the transfer of the Units through DWAC for purposes of this Section 3(a)(vi) .

(vii) If acting as sales agent hereunder, a Manager shall provide written confirmation (which may be by e-mail) to the Partnership as soon as is reasonably practicable following the close of trading on the Primary Stock Exchange each day in which Units are sold under this Agreement setting forth (A) the number of Units sold on such day, (B) the gross offering proceeds received from such sale, and (C) the compensation payable by the Partnership to such Manager with respect to such sales.

Any obligation of a Manager to use its reasonable efforts to sell the Units on behalf of the Partnership as sales agent 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 6 .

If such 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, such Manager and the Partnership will enter into a Terms Agreement setting forth the terms of such Placement.

(ii) The terms set forth in a Terms Agreement will not be binding on the Partnership or such Manager unless and until the Partnership and such Manager have each executed such Terms Agreement accepting all of the terms of such Terms Agreement.

(i) against any and all loss, liability, claim, damage and expense whatsoever (including the reasonable cost of investigation), to which each of the Managers or any such person may become subject with respect to the Units, (A) arising out of or based upon any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement or the Prospectus (or any amendment or supplement to such documents), or the omission or alleged omission therefrom of a material fact required to be stated therein or necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading, or (B) resulting from the use of any “ issuer free writing prospectus ” (as defined in Rule 433 of the Rules and Regulations) relating to the Units, whether or not filed by the Partnership or on its behalf;

(ii) against any and all loss, liability, claim, damage and expense whatsoever, as incurred, to the extent of the aggregate amount paid in settlement of any litigation, or any investigation or proceeding by any governmental agency or body, commenced or threatened, or of any claim whatsoever based upon any such untrue statement or omission, or any such alleged untrue statement or omission; provided that (subject to Section 7(d) below) any such settlement is effected with the written consent of the Partnership; and

32

(iii) against any and all expense whatsoever, as incurred (including, subject to Section 7(c) hereof, the fees and disbursements of counsel chosen by the Managers), reasonably incurred in investigating, preparing or defending against any litigation, or any investigation or proceeding by any governmental agency or body, commenced or threatened, or any claim whatsoever based upon any such untrue statement or omission, or any such alleged untrue statement or omission, to the extent that any such expense is not paid under clause (i) or (ii)  above;

provided, however , that the indemnity set forth in this Section 7(a) shall not apply to any loss, liability, claim, damage or expense to the extent arising out of any untrue statement or omission or alleged untrue statement or omission contained in the Registration Statement or any Prospectus, or any prospectus other than the Prospectus (or any amendment or supplement to such documents) in reliance upon and in conformity with written information furnished to the Partnership by or on behalf of any Manager expressly for use in the Registration Statement or any Prospectus, or prospectus other than the Prospectus (or any amendment or supplement to such documents).

(b) Each Manager, severally and not jointly, agrees to indemnify and hold harmless the Partnership, the directors of the General Partner (and any other individual serving a similar function for the Partnership) and the respective officers of the General Partner and, if applicable, the Partnership, who signed the Registration Statement, and each person, if any, who controls the Partnership within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act, against any and all loss, liability, claim, damage and expense described in the indemnity contained in Section 7(a) (provided that, subject to Section 7(d) below, with respect to indemnification of the nature contemplated by Section 7(a)(ii) , such indemnification by each Manager for a settlement of any such loss, liability, claim, damage and expense must be effected with the written consent of such affected Manager), as incurred, but only with respect to any untrue statements or omissions, or alleged untrue statements or omissions, made in the Registration Statement or any Prospectus, or prospectus, other than the Prospectus (or any amendment or supplement to such documents), in reliance upon and in conformity with written information furnished to the Partnership by or on behalf of such Manager or expressly for use in the Registration Statement, the Basic Prospectus or any Prospectus, or prospectus, other than the Prospectus (or any amendment or supplement to such documents). The Partnership acknowledges that, except as may be agreed in writing between all the parties after the date of this Agreement, or by the Partnership with respect to such Manager, the only information furnished in writing by or on behalf of the Managers for inclusion in the Registration Statement or the Prospectus, or prospectus, other than the Prospectus, or in any amendment or supplement thereto consists of the names of the Managers and the statement that such Manager will not engage in any transactions that stabilize the Common Units under the caption “ Plan of Distribution ” in the Prospectus Supplement.

(c) Each indemnified party shall give written notice as promptly as reasonably practicable to each indemnifying party of any action commenced against it in respect of which indemnity may be sought hereunder, but failure to so notify an indemnifying party shall not relieve such indemnifying party from any liability hereunder to the extent it is not materially prejudiced as a result thereof and in any event shall not

33

relieve it from any liability which it may have otherwise than on account of this indemnity agreement. In the case of parties indemnified pursuant to Section 7(a) above, counsel to the indemnified parties shall be selected by the Managers, and, in the case of parties indemnified pursuant to Section 7(b) above, counsel to the indemnified parties shall be selected by the Partnership; provided , however , that if it so elects within a reasonable time after receipt of such notice, an indemnifying party, jointly with any other indemnifying parties receiving such notice, may assume the defense of such action with counsel chosen by it and approved by the indemnified parties defendant in such action, unless such indemnified parties reasonably object to such assumption on the ground that there may be legal defenses available to them which are different from or in addition to those available to such indemnifying party. If an indemnifying party assumes the defense of such action, the indemnifying parties shall not be liable for any fees and expenses of counsel for the indemnified parties incurred thereafter in connection with such action; provided, however , that the indemnifying party shall pay the fees and expenses of separate counsel for the indemnified party if (i) the indemnifying party has agreed to pay such fees and expenses or (ii) counsel for the indemnified party reasonably determines that representation of both the indemnifying party and the indemnified party by the same counsel would create a conflict of interest. An indemnifying party may participate at its own expense in the defense of any such action; provided, however , that counsel to the indemnifying party shall not (except with the consent of the indemnified party) also be counsel to the indemnified party. 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 (including any Managers) in connection with any one action or separate but similar or related actions arising out of the same general allegations or circumstances. No indemnifying party shall, without the prior written consent of the indemnified parties, settle or compromise or consent to the entry of any judgment with respect to any litigation, or any investigation or proceeding by any governmental agency or body, commenced or threatened, or any claim whatsoever in respect of which indemnification or contribution could be sought under this Section 7 (whether or not the indemnified parties are actual or potential parties thereto), unless such settlement, compromise or consent (i) includes an unconditional release of each indemnified party from all liability arising out of such litigation, investigation, proceeding 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 at any time an indemnified party shall have requested an indemnifying party to reimburse the indemnified party for reasonable fees and expenses of counsel, such indemnifying party agrees that it shall be liable for any settlement of the nature contemplated by Section 7(a)(ii) effected without its written consent if (i) such settlement is entered into more than 45 days after receipt by such indemnifying party of the aforesaid request, (ii) such indemnifying party shall have received notice of the terms of such settlement at least 30 days prior to such settlement being entered into and (iii) such indemnifying party shall not have reimbursed such indemnified party in accordance with such request prior to the date of such settlement. Notwithstanding the immediately preceding 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, an indemnifying party shall not be liable for any settlement of the nature contemplated by Section 7(a)(ii) effected without its consent if such indemnifying party (i) reimburses such indemnified party in accordance with such request to the extent it considers

34

such request to be reasonable and (ii) provides written notice to the indemnified party substantiating the unpaid balance as unreasonable, in each case prior to the date of such settlement.

(e) If the indemnification provided for in this Section 7 is for any reason unavailable to or insufficient to hold harmless an indemnified party in respect of any losses, liabilities, claims, damages or expenses referred to in Section 7(a) or Section 7(b) , as applicable, then each indemnifying party shall contribute to the aggregate amount of such losses, liabilities, claims, damages and expenses incurred by such indemnified party, as incurred, (i) in such proportion as is appropriate to reflect the relative benefits received by the Partnership, on the one hand, and the Managers, on the other hand, from the offering of the Units pursuant to this Agreement or (ii) if the allocation provided by clause (i) 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, on the one hand, and of any of the Managers, on the other hand, in connection with the statements or omissions which resulted in such losses, liabilities, claims, damages or expenses, as well as any other relevant equitable considerations. The relative benefits received by the Partnership, on the one hand, and the Managers, on the other hand, in connection with the offering of the Units pursuant to this Agreement shall be deemed to be in the same respective proportions as the total Net Proceeds from the offering of the Units pursuant to this Agreement received by the Partnership, and the total compensation received by any of the Managers, in each case as provided in Section 3(a)(v) or Section 3(b) and the relevant Terms Agreement, bear to the gross sales price of the Units sold by or through any of the Managers. The relative fault of the Partnership, on the one hand, and any of the Managers, on the other hand, shall be determined by reference to, among other things, whether any such untrue or alleged untrue statement of a material fact or omission or alleged omission to state a material fact relates to information supplied by the Partnership or by any of the Managers and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. The Partnership and the Managers agree that it would not be just and equitable if contribution pursuant to this Section 7(e) were determined by pro rata allocation or by any other method of allocation which does not take account of the equitable considerations referred to above in this Section 7(e) . The aggregate amount of losses, liabilities, claims, damages and expenses incurred by an indemnified party and referred to above in this Section 7(e) shall be deemed to include any legal or other expenses reasonably incurred by such indemnified party in investigating, preparing or defending against any litigation, or any investigation or proceeding by any governmental agency or body, commenced or threatened, or any claim whatsoever based upon any such untrue or alleged untrue statement or omission or alleged omission. Notwithstanding the provisions of this Section 7(e) , each Manager shall not be required to contribute any amount in excess of the compensation received by it pursuant to this Agreement, as determined in accordance with Section 3(a)(v) or Section 3(b) and the relevant Terms Agreement. 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. For purposes of this Section 7(e) , each person, if any, who controls any Manager within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act, shall have the same rights to contribution as such Manager; and each director and officer of the General Partner or, if applicable, the Partnership, and each person, if any, who controls the Partnership within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act shall have the same rights to contribution as the Partnership.

35

The obligations of the parties under this Section 7(e) shall be in addition to any liability which the parties may otherwise have.

Section 8. Representations and Agreements to Survive Delivery . The indemnity and contribution agreements of the parties contained in Section 7 and the warranties and representations of the Partnership contained in this Agreement or in certificates delivered pursuant hereto shall remain in full force and effect regardless of any investigation made by or on behalf of any of the Managers, its partners, directors, officers or any person (including each partner, officer or director of such person) who controls such Manager within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act, or by or on behalf of the Partnership, its directors, officers or any person who controls the Partnership within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act, and shall survive any termination of this Agreement or the issuance and delivery of the Units.

Section 9. Termination .

(a) The Partnership 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 any of the Managers for the Partnership, the obligations of the Partnership, including in respect of compensation of the Managers, shall remain in full force and effect notwithstanding the termination, and (ii) the reimbursement, indemnification and contribution agreements contained in Section 5 and Section 7 , the provisions of Section 8 , Section 10 , Section 11 , Section 13 , Section 17 and Section 18 hereof, and (A) the representations and warranties and (B) the covenants and agreements of the Partnership in this Agreement shall remain in full force and effect regardless of any termination of this Agreement.

(b) Each Manager shall have the right, by giving written notice as hereinafter specified, to terminate its own obligations under the provisions of this Agreement relating to the solicitation of offers to purchase the Units in its sole discretion at any time. Any such termination shall have no effect on the obligations of any other Manager under this Agreement and shall be without liability of any party to any other party.

(c) This Agreement shall remain in full force and effect until the earlier of (i) its termination pursuant to Section 9(a) above or the termination of all Managers’ obligations pursuant to Section 9(b) above or otherwise by mutual agreement of the parties and (ii) the sale of all of the Units authorized hereunder; provided , however , that any such termination shall in all cases be deemed to provide that Section 5 , Section 7 , Section 8 , Section 10 , Section 11 , Section 13 , Section 17 and Section 18 shall remain in full force and effect, unless otherwise agreed by the parties.

(d) Any termination of this Agreement shall be effective on the date specified in such notice of termination; provided , however , that such termination shall not be effective until the close of business on the date of receipt of such notice by any Manager or the Partnership, as the

36

case may be. If such termination shall occur prior to the Settlement Date for any sale of Units sold prior to such termination, such sale shall settle in accordance with the provisions of Section 3(a)(vi) or Section 3(b) of this Agreement and the relevant Terms Agreement.
