SECTION 3.  Sale and Delivery to the Managers; Settlement.

(a)                                 Sale of Units.  On the basis of the representations and warranties herein contained and subject to the terms and conditions herein set forth, the Partnership agrees to issue and sell from time to time through the Managers, acting as sales agents, or directly to the Managers acting as principals, and each Manager agrees to use its commercially reasonable efforts to sell, as sales agent for the Partnership, the Units on the following terms:

(1)                     The Units are to be sold by any one of the Managers on a daily basis or otherwise as shall be agreed to by the Partnership and such Manager on any day that (A) is a trading day for the NYSE (other than a day on which the NYSE is scheduled to close prior to its regular weekday closing time), (B) the Partnership, through any of the individuals listed as authorized representatives of the Partnership on Exhibit A hereto (which may be updated from time to time by a certificate from the Partnership to the Managers) (the “Authorized Partnership Representatives”) has instructed any of the individuals listed as authorized representatives of such Manager on Exhibit A hereto (which may be updated from time to time by a certificate from such Manager to the Partnership) (the “Authorized Manager Representatives”) by telephone (confirmed promptly by electronic mail) to make such sales, (C) the Partnership has satisfied its obligations under Section 6 of this Agreement and (D) no Manager shall have an obligation to offer or sell any Units in the event an offer or sale of the Units on behalf of the Partnership may, in the judgment of such Manager, 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 such Manager reasonably believes it may be deemed an “underwriter” under the Act in a transaction that is other than by means set forth under Section 3(a)(4) hereof. The Partnership will designate (i) the maximum amount of the Units to be sold by such Manager daily as agreed to by such Manager (in any event not in excess of the amount available for issuance under the Prospectus and the currently effective Registration Statement) and (ii) the minimum price per Unit at which such Units may be sold. Subject to the terms and conditions hereof, such Manager shall use its commercially reasonable efforts to sell on a particular day all of the Units designated for the sale by the Partnership on such day. The gross sales price of the Units sold under this Section 3(a) shall be the prevailing market price for the Partnership’s Common Units sold by such Manager under this Section 3(a) on the NYSE at the time of sale of such Units.  For the avoidance of doubt, the Partnership shall submit instructions to sell Units to only one Manager, if any, on any single trading day.

(2)                     The Partnership acknowledges and agrees that (i) there can be no assurance that any Manager will be successful in selling  Units, (ii) no Manager will incur any liability or obligation to the 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 commercially reasonable efforts consistent with its normal trading and sales practices to sell such Units as required under this Section 3 and (iii) 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 in writing pursuant to a Terms Agreement.

17

(3)                     Notwithstanding the foregoing, the Partnership, through any of the Authorized Partnership Representatives, may instruct the Authorized Manager Representatives by telephone (confirmed promptly by electronic mail) not to sell Units if such sales cannot be effected at or above the price designated by the Partnership in any such instruction. The Partnership or any Manager may, upon notice to the other party hereto by telephone (confirmed promptly by electronic mail), suspend or terminate the offering of the Units with respect to which such Manager is acting as sales agent for any reason and at any time; 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. During any such period of suspension, the Partnership shall not be obligated to deliver (or cause to be delivered) any of the documents referred to in Sections 4(n)—(p), be deemed to affirm any of the representations or warranties contained in this Agreement, or be obligated to conduct any due diligence session as referred to in Section 4(l) until the termination of the suspension and the recommencement of the offering of the Units pursuant to this Agreement (which recommencement shall constitute a Representation Date).

(4)                     Subject to the terms of a Terms Agreement, the Managers may sell Units (i) by any method permitted by law deemed to be an “at the market” offering as defined in Rule 415 of the Securities Act, including without limitation sales made directly on the NYSE, on any other trading market for the Common Units, (ii) to or through a market maker, or (iii) directly on or through an electronic communication network, a “dark pool” or any similar market venue.  Subject to the terms of a Terms Agreement, the Managers may also sell Units by any other method permitted by law, including but not limited to in privately negotiated transactions or by such other method as shall be agreed by the Partnership and such Manager pursuant to a Terms Agreement.

(5)                     The compensation to each Manager for sales of the Units with respect to which such Manager acts as sales agent under this Agreement shall be up to 2.0% of the gross sales price of the Units sold pursuant to this Section 3(a) and payable as described in Section 3(b) below. The foregoing rate of compensation shall not apply when any Manager acts as principal, in which case the Partnership may sell Units to such Manager as principal at a price mutually agreed upon at the relevant Applicable Time pursuant to a Terms Agreement.

(6)                     Each Manager acting as sales agent hereunder shall provide written confirmation (which may be by electronic mail) to the Partnership following the close of trading on the NYSE each day in which the Units with respect to which such Manager is acting as sales agent are sold under this Section 3(a) setting forth the number of the Units sold on such day, the Gross Proceeds (as defined below), the compensation payable by the Partnership to such Manager with respect to such sales and the Net Proceeds (as defined below) payable to the Partnership.

(b)                                 Settlement of Units.  Settlement for sales of Units pursuant to Section 3(a) 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, a “Settlement Date”).  The amount of proceeds to be delivered to the Partnership on a Settlement Date against receipt of the

18

Units sold will be equal to either (a) the aggregate sales price received by the Manager acting as sales agent at which such Units were sold (the “Gross Proceeds”), or (b) the Gross Proceeds after deduction for (i) such Manager’s commission, discount or other compensation for such sales payable by the Partnership pursuant to Section 3(a)(5) hereof, (ii) any other amounts due and payable by the Partnership to such Manager hereunder pursuant to Section 5 hereof, and (iii) any transaction fees imposed by any governmental or self-regulatory organization in respect of such sales (the “Net Proceeds”).

(c)                                  Delivery of Units.  On or before each Settlement Date, the Partnership will, or will cause its transfer agent to, electronically transfer the Units being sold by crediting the applicable Manager’s or its designee’s account (provided such Manager shall have given the Partnership written notice of such designee prior to the Settlement Date) at The Depository Trust Company (“DTC”) through its Deposit and Withdrawal at Custodian System or by such other means of delivery as may be mutually agreed upon by the Partnership and such Manager which in all cases shall be freely tradable, transferable units eligible for delivery through DTC.  On each Settlement Date, the applicable Manager will deliver the related (a) Gross Proceeds or (b) Net Proceeds, as mutually agreed between the Partnership and the applicable Manager, in same day funds to an account designated by the Partnership on, or prior to, the Settlement Date.  The Partnership agrees that if the Partnership, or its transfer agent (if applicable), defaults in its obligation to deliver Units on a Settlement Date, the Partnership agrees that in addition to and in no way limiting the rights and obligations set forth in Section 7(a) hereto, it will (i) indemnify and hold the applicable Manager harmless against any loss, liability, claim, damage, or expense whatsoever (including reasonable legal fees and expenses), as incurred, arising out of or in connection with such default by the Partnership or its transfer agent and (ii) pay to such Manager any commission to which it would otherwise have been entitled absent such default.  If any Manager breaches this Agreement by failing to deliver Net Proceeds to the Partnership on any Settlement Date for the Units delivered by the Partnership, the Manager will pay, until such Net Proceeds are delivered to the Partnership, the Partnership interest based on the effective overnight federal funds rate on such unpaid amount less any compensation due to the Manager. In the event that a Manager delivers the Gross Proceeds to the Partnership at a Settlement Date, such Manager’s commission, discount or other compensation for such sales payable by the Partnership pursuant to Section 3(a)(5) shall be set forth and invoiced in a periodic statement from the Manager to the Partnership and payment of such amounts shall be made promptly by the Partnership after it receipt thereof.

(d)                                 Limitations on Offering Size.  Under no circumstances shall the Partnership cause or request the offer or sale of any Units, if after giving effect to the sale of such Units, the aggregate offering price of the Units sold pursuant to this Agreement would exceed the lesser of (A) the amount available for offer and sale under the currently effective Registration Statement, and (B) the amount authorized from time to time to be issued and sold under this Agreement by the Partnership and notified to the Managers in writing.  Under no circumstances shall the Partnership cause or request the offer or sale of any Units pursuant to this Agreement at a price lower than the minimum price authorized from time to time by the Partnership and notified to the Managers in writing. Further, under no circumstances shall the aggregate offering price of Units sold pursuant to this Agreement, including any separate underwriting or similar agreement covering principal transactions described in Section 1 of this Agreement, exceed $250,000,000.

19

(e)                                  Black-out Limitations. Notwithstanding any other provision of this Agreement, the Partnership shall not offer or sell, or instruct any Manager to offer or sell, any Units through such Manager as agent hereunder (and, by notice to such Manager given by telephone (confirmed promptly by facsimile or email), shall cancel any instructions for any such offer or sale of any Units prior to the commencement of the periods referenced below), and such Manager shall not be obligated to make any such offer or sale of Units, in each case, (i) during any period in which the Partnership is in possession of material non-public information or (ii) except as provided in Section 3(f)(i) hereof, at any time during the period commencing on the 10th business day prior to the time the Partnership issues a press release containing, or shall otherwise publicly announce, its earnings or revenues for a fiscal period or periods (each, an “Earnings Announcement”) through and including the time that is 24 hours after the time that the Partnership files a Quarterly Report on Form 10-Q or an Annual Report on Form 10-K (a “Filing Time”) that includes consolidated financial statements as of and for the same fiscal period or periods, as the case may be, covered by such Earnings Announcement.

(f)                                   If the Partnership wishes to offer or sell Units to any Manager as agent at any time during the period from and including an Earnings Announcement through and including the time that is 24 hours after the corresponding Filing Time, the Partnership shall first (i) prepare and deliver to such Manager (with a copy to counsel to such Manager) a Current Report on Form 8-K that includes substantially the same financial and related information (together with management’s discussion and analysis thereof) that was included in such Earnings Announcement (other than any earnings projections and similar forward-looking data and officers’ quotations) (each, an “Earnings 8-K”), in form and substance reasonably satisfactory to such Manager, and, prior to its filing, obtain the written consent of such Manager to such filing (which consent shall not be unreasonably withheld), (ii) provide such Manager with the officers’ certificate, opinions and letters of counsel and accountants’ letter specified in Section 4(n)-(p) hereof, (iii) afford such Manager the opportunity to conduct a due diligence review in accordance with Section 4(l) hereof prior to filing such Earnings 8-K and (iv) file such Earnings 8-K with the Commission, then the provision of clause (ii) of Section 3(e) shall not be applicable for the period from and after the time at which the foregoing conditions shall have been satisfied (or, if later, the time that is 24 hours after the time that the relevant Earnings Announcement was first publicly released) through and including the time that is 24 hours after the Filing Time of the relevant Quarterly Report on Form 10-Q or Annual Report on Form 10-K, as the case may be.  For purposes of clarity, the parties hereto agree that (A) the delivery of any officers’ certificate, opinion or letter of counsel or accountants’ letter pursuant to this Section 3(f) shall not relieve the Partnership from any of its obligations under this Agreement with respect to any Quarterly Report on Form 10-Q or Annual Report on Form 10-K, as the case may be, including, without limitation, the obligation to deliver officers’ certificates, opinions and letters of counsel and accountants’ letters as provided in Section 4(n)-(p) hereof, and (B) this Section 3(f) shall in no way affect or limit the operation of clause (i) of Section 3(e) hereof, which shall have independent application.

20

SECTION 4.  Covenants of the Partnership.  The Partnership covenants with the Managers as follows:

(a)                                 Registration Statement Amendments.  After the date of this Agreement and during any period in which a Prospectus relating to any Units is required to be delivered by any Manager under the Securities Act (including in circumstances where such requirement may be satisfied pursuant to Rule 172 under the Securities Act), (i) the Partnership will notify  the Managers promptly of the time when any subsequent amendment to the Registration Statement, other than documents incorporated by reference, has been filed with the Commission and/or has become effective or any subsequent supplement to the Prospectus has been filed and of any comment letter from the Commission or any request by the Commission for any amendment or supplement to the Registration Statement or Prospectus or for additional information relating thereto; (ii)  the Partnership will not file any amendment or supplement to the Registration Statement or Prospectus, other than documents incorporated by reference, relating to the Units or a security convertible into the Units unless a copy thereof has been submitted to  the Managers within a reasonable period of time before the filing and the Managers have not reasonably objected thereto, unless the Partnership shall have determined based upon the advice of counsel that such amendment, supplement or filing is required by law  (provided, however, that the failure of any Manager to make such objection shall not relieve the Partnership of any obligation or liability hereunder, or affect such Manager’s right to rely on the representations and warranties made by the Partnership in this Agreement), and the Partnership will furnish to  the Managers at the time of filing thereof a copy of any document that upon filing is deemed to be incorporated by reference into the Registration Statement or Prospectus, except for those documents available via EDGAR; and (iii) the Partnership will cause each amendment or supplement to the Prospectus, other than documents incorporated by reference, to be filed with the Commission as required pursuant to the applicable paragraph of Rule 424(b) of the Securities Act (without reliance on Rule 424(b)(8) of the Securities Act).

(b)                                 Notice of Commission Stop Orders.  The Partnership will advise the Managers, promptly after they receive notice or obtain knowledge thereof, of the issuance or threatened issuance by the Commission of any stop order suspending the effectiveness of the Registration Statement or of any other order preventing or suspending the use of the Prospectus, or of the suspension of the qualification of the Units for offering or sale in any jurisdiction or of the loss or suspension of any exemption from any such qualification, or of the initiation or threatening of any proceedings for any of such purposes, or of any examination pursuant to Section 8(e) of the Securities Act concerning the Registration Statement or if the Partnership becomes the subject of a proceeding under Section 8A of the Securities Act in connection with the offering of the Units.  The Partnership will use its reasonable efforts to prevent the issuance of any stop order, the suspension of any qualification of the Units for offering or sale and any loss or suspension of any exemption from any such qualification, and if any such stop order is issued or any such suspension or loss occurs, to obtain the lifting thereof as soon as practicable.

(c)                                  Delivery of Registration Statement and Prospectus.  The Partnership will furnish to the Managers and their counsel (at the expense of the Partnership) copies of the Registration Statement, the Prospectus (including all documents incorporated by reference therein) and all amendments and supplements to the Registration Statement or Prospectus that are filed with the Commission during any period in which a Prospectus relating to the Units is required to be

21

delivered under the Securities Act (including, if requested, all documents filed with the Commission during such period that are deemed to be incorporated by reference therein), in each case as soon as reasonably practicable and in such quantities and at such locations as the Managers may from time to time reasonably request (to the extent not previously delivered or filed on EDGAR or any successor system thereto).

(d)                                 Continued Compliance with Securities Laws.  If at any time when a Prospectus is required by the Securities Act or the Exchange Act to be delivered in connection with a pending sale of the Units (including, without limitation, pursuant to Rule 172), any event shall occur or condition shall exist as a result of which it is necessary, in the opinion of counsel for the Managers or for the Partnership, to amend the Registration Statement or amend or supplement the Prospectus in order that the Prospectus will not include any untrue statement of a material fact or omit to state a material fact necessary in order to make the statements therein not misleading in the light of the circumstances existing at the time it is delivered to a purchaser, or if it shall be necessary, in the opinion of such counsel, at any such time to amend the Registration Statement or amend or supplement the Prospectus in order to comply with the requirements of the Securities Act, the Partnership will promptly notify the applicable Manager to suspend the offering of Units during such period and the Partnership will promptly prepare and file with the Commission such amendment or supplement as may be necessary to correct such statement or omission or to make the Registration Statement or the Prospectus comply with such requirements, and the Partnership will furnish to the Managers such number of copies of such amendment or supplement as the Managers may reasonably request.

(e)                                  Blue Sky and Other Qualifications.  The Partnership will arrange, if necessary, for the qualification of the Units for sale under the laws of such jurisdictions as any Manager may designate, will maintain such qualifications in effect so long as required for the distribution of the Units and will pay any fee of FINRA in connection with its review of the offering; provided that in no event shall the Partnership be obligated to qualify to do business in any jurisdiction where it is not now so qualified or to take any action that would subject it to service of process in suits, other than those arising out of the offering or sale of the Units, in any jurisdiction where it is not now so subject.

The foregoing sentence shall not apply to (x) the Common Units to be offered and sold through any Manager pursuant to this Agreement and (y) equity incentive awards approved by the Board of Directors of the General Partner or the compensation committee thereof or the issuance of Common Units upon vesting thereof.

(i)                                     files the Prospectus relating to the Units or amends or supplements the Registration Statement or the Prospectus relating to the Units by means of a post-effective amendment, sticker, or supplement but not by means of incorporation of documents by reference into the Registration Statement or the Prospectus relating to the Units;

(ii)                                  files an annual report on Form 10-K under the Exchange Act;

(iii)                               files a quarterly report on Form 10-Q under the Exchange Act; or

(2)                     at any time the Units are delivered to any Manager as principal pursuant to a Terms Agreement; and

(3)                                 at any other time reasonably requested by the Managers (each such date of filing of one or more of the documents referred to in clauses (1)(i) through (iv) and any time of request pursuant to this Section 4(n) shall be a “Representation Date”),

the Partnership shall furnish the Managers (or in the case of clause (2) above, the relevant Manager party to such Terms Agreement) with a certificate, in the form attached hereto as Exhibit D within three Trading Days of any Representation Date.  The requirement to provide a certificate under this Section 4(n) shall be waived for any Representation Date occurring at a time at which no instruction by the Partnership to any Manager to sell Units under this Agreement is in effect, which waiver shall continue until the earlier to occur of the date the Partnership delivers an instruction to any Manager to sell Units pursuant to Section 3(a) hereof (which for such calendar quarter shall be considered a Representation Date) and the next occurring Representation Date.  Notwithstanding the foregoing, if the Partnership subsequently decides to sell Units following a Representation Date when the Partnership relied on such waiver and did not provide the Managers with a certificate under this Section 4(n), then before the Partnership delivers an instruction pursuant to Section 3(a) or any Manager sells any Units, the Partnership shall provide such Manager with a certificate, in the form attached hereto as Exhibit D, dated the date of such instruction.

(o)                                 Legal Opinion of Partnership Counsel.  On or prior to the date that the first Units are sold pursuant to the terms of this Agreement and within three Trading Days of each Representation Date with respect to which the Partnership is obligated to deliver a certificate in the form attached hereto as Exhibit D for which no waiver is applicable, the Partnership shall cause to be furnished to the Managers a written opinion of Vinson & Elkins L.L.P. (“Partnership Counsel”), or other counsel satisfactory to the Managers, in form and substance satisfactory to the Managers and their counsel, dated the date that the opinion is required to be delivered, substantially similar to the form attached hereto as Exhibit C, modified, as necessary, to relate to the Registration Statement and the Prospectus as then amended or supplemented; provided,

24

however, that in lieu of such opinions for subsequent Representation Dates, counsel may furnish the Managers with a letter (a “Reliance Letter”) to the effect that the Managers may rely on a prior opinion delivered under this Section 4(o) 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 the Registration Statement and the Prospectus as amended or supplemented at such Representation Date).

(p)                                 Comfort Letter.  On or prior to the date that the first Units are sold pursuant to the terms of this Agreement and within three Trading Days of each Representation Date with respect to which the Partnership is obligated to deliver a certificate in the form attached hereto as Exhibit D for which no waiver is applicable, the Partnership shall cause KPMG LLP (and any other independent accountants whose report is included in the Registration Statement or the Prospectus) to furnish the Managers a letter or letters (the “Comfort Letters”) with respect to each of the Antero Entities, dated the date the Comfort Letter is delivered, in form and substance satisfactory to the Managers, each (i) confirming that they are an independent registered public accounting firm within the meaning of the Securities Act, the Exchange Act and the PCAOB, (ii) stating, as of such date, the conclusions and findings of such firm with respect to the financial information and other matters ordinarily covered by accountants’ “comfort letters” to underwriters in connection with registered public offerings (the first such letter, the “Initial Comfort Letter”) and (iii) updating the Initial Comfort Letter with any information that would have been included in the Initial Comfort Letter had it been given on such date and modified as necessary to relate to the Registration Statement and the Prospectus, as amended and supplemented to the date of such letter.

(q)                                 Opinion of Counsel for the Managers.  On or prior to the date that the first Units are sold pursuant to the terms of this Agreement and within three Trading Days of each Representation Date with respect to which the Partnership is obligated to deliver a certificate in the form attached hereto as Exhibit D for which no waiver is applicable, the Managers shall have received the favorable written opinion or opinions of Latham & Watkins LLP, counsel for the Managers, dated such date, with respect to such matters as the Managers may reasonably request; provided, however, that in lieu of such opinions for subsequent Representation Dates, counsel may furnish the Managers with a Reliance Letter to the effect that the Managers may rely on a prior opinion delivered under this Section 4(q) 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 the Registration Statement and the Prospectus as amended or supplemented at such Representation Date).

(r)                                    Market Activities.  The Partnership will not, directly or indirectly, (i) take any action designed to cause or result in, or that constitutes or might reasonably be expected to constitute, the stabilization or manipulation of the price of any security of the Partnership to facilitate the sale or resale of the Units or (ii) sell, bid for, or purchase the Units to be issued and sold pursuant to this Agreement, or pay anyone any compensation for soliciting purchases of the Units to be issued and sold pursuant to this Agreement other than the Managers; provided, however, that the Partnership may bid for and purchase its Common Units in accordance with Rule 10b-18 under the Exchange Act; and provided further, that no such bids or purchases shall be made by the Partnership during the three Trading Days before or after any sale of any Units pursuant to this Agreement.

25

(s)                                   No Offer to Sell.  Other than a Permitted Free Writing Prospectus, the Partnership will not, directly or indirectly, make, use, prepare, authorize, approve or refer to any free writing prospectus relating to the Units to be sold by the Managers as principal or agent hereunder.

(t)                                    Sarbanes-Oxley Act.  The Partnership will take all necessary action to comply, in all material respects, with all effective applicable provisions of the Sarbanes-Oxley Act.

(u)                                 Regulation M.  If the Partnership 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 Common Units, it shall promptly notify the Managers and sales of the Units under this Agreement shall be suspended until that or other exemptive provisions have been satisfied in the judgment of each party.

SECTION 5.  Payment of Expenses.

The Partnership Parties, jointly and severally, agree to pay the costs and expenses relating to the following matters:  (i) the preparation, printing or reproduction and filing with the Commission of the Registration Statement (including financial statements and exhibits thereto), the Prospectus, and each amendment or supplement; (ii) the printing (or reproduction) and delivery (including postage, air freight charges and charges for counting and packaging) of such copies of the Registration Statement and the Prospectus, and all amendments or supplements as may, in each case, be reasonably requested for use in connection with the offering and sale of the Units; (iii) the preparation, printing, authentication and delivery of certificates for the Units, including any stamp or transfer taxes in connection with the sale of the Units; (iv) the printing (or reproduction) and delivery of this Agreement, any blue sky memorandum and all other agreements or documents printed (or reproduced) and delivered in connection with the offering of the Units; (v) any registration or qualification of the Units for offer and sale under the blue sky laws of the several states (including filing fees and the reasonable fees and expenses of counsel for the Managers relating to such registration and qualification); (vi) any filings required to be made with FINRA (including filing fees and the reasonable fees and expenses of counsel for the Managers relating to such filings); (vii) the transportation and other expenses incurred by or on behalf of Partnership representatives in connection with presentations to prospective purchasers of the Units; (viii) the fees and expenses of the Partnership’s accountants and the fees and expenses of counsel (including local and special counsel) for the Partnership; (ix) the reasonable fees, disbursements and expenses of one designated outside counsel for the Managers in an amount not to exceed (A) $75,000 in connection with the negotiation and entry into this Agreement (which shall include all matters required to be completed in connection with the execution of this Agreement, including the preparation and filing of the Registration Statement and the Prospectus Supplement) and (B) $20,000 in connection with each review of diligence materials and the documents and other deliverables referred to in Section 4 hereof in connection with each Representation Date; and (x) all other costs and expenses incident to the performance by the Partnership of its obligations hereunder.  Except as otherwise provided in this Section 5, the Managers will pay all of their own out-of-pocket costs and expenses incurred in connection with entering into this Agreement and the transactions contemplated by this Agreement.

(b)                                 No Material Notices.  None of the following events shall have occurred and be continuing: the occurrence of any event that makes any material statement made in the Registration Statement or the Prospectus, or any material document incorporated or deemed to be incorporated therein by reference, untrue in any material respect or that requires the making of any changes in the Registration Statement, related Prospectus, or such documents so that, in the case of the Registration Statement, it will not contain any materially untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary to make the statements therein not misleading and, that in the case of the Prospectus, it will not contain any materially untrue statement of a material fact or omit to state any 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.

(c)                                  Material Changes.  Except as contemplated in the Prospectus, or disclosed in the Partnership’s reports filed with the Commission, there shall not have been any material adverse change in the general affairs, condition (financial or other), business, assets or results of operations of the Partnership and its subsidiaries taken as a whole, whether or not arising from transactions in the ordinary course of business.

SECTION 7.  Indemnification and Contribution.

(a)                                 The Partnership Parties agree, jointly and severally, to indemnify and hold harmless each Manager, its affiliates, directors, officers, employees and agents, and each person who controls any Manager within the meaning of either the Securities Act or the Exchange Act against any and all losses, claims, damages or liabilities, joint or several, to which they or any of them may become subject under the Securities Act, the Exchange Act or other federal or state statutory law or regulation, at common law or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon (i) any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement, the Prospectus, any “road show” (as defined in Rule 433) not constituting an Issuer Free Writing Prospectus (a “Non-Prospectus Road Show”) or any Issuer Free Writing Prospectus, or in any amendment thereof or supplement thereto, (ii) the omission or alleged omission to state in the Registration Statement a material fact required to be stated therein or necessary to make the statements therein not misleading or (iii) the omission or alleged omission to state in any Prospectus, any Non-Prospectus Road Show or any Issuer Free Writing Prospectus a material fact necessary to make the statements therein, in light of the circumstances under which they were made, not misleading, and agrees to reimburse each such indemnified party, as incurred, for any legal or other expenses reasonably incurred by them in connection with investigating or defending any such loss, claim, damage, liability or action; provided, however, that the Partnership Parties 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 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 Partnership Parties by or on behalf of the Managers specifically for inclusion therein, it being understood and agreed that the only such information furnished by or on behalf of the Managers consists of the information described as such in Section 7(b) hereof.  This indemnity agreement will be in addition to any liability which the Partnership Parties may otherwise have.

(b)                                 Each Manager, severally and not jointly, agrees to indemnify and hold harmless the Partnership Parties, their directors, each of their officers who signs the Registration Statement, and each person who controls the Partnership Parties within the meaning of either the

28

Securities Act or the Exchange Act, to the same extent as the foregoing indemnity to  such Manager, but only with reference to any written information furnished to the Partnership Parties by or on behalf of the Managers specifically for inclusion in the Registration Statement and the Prospectus, it being understood and agreed that the only such information furnished by or on behalf of the Managers for inclusion in the Registration Statement and the Prospectus consists of the name of each Manager.  This indemnity agreement will be in addition to any liability which each Manager may otherwise have.

(c)                                  Promptly after receipt by an indemnified party under this Section 7 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 this Section 7, notify the indemnifying party in writing of the commencement thereof; but the failure so to notify the indemnifying party (i) will not relieve it from liability under paragraph (a) or (b) above unless and to the extent it did not otherwise learn of such action and such failure results in the forfeiture by the indemnifying party of substantial rights and defenses and (ii) will not, in any event, relieve the indemnifying party from any obligations to any indemnified party other than the indemnification obligation provided in paragraph (a) or (b) above.  The indemnifying party shall be entitled to appoint counsel of the indemnifying party’s choice at the indemnifying party’s expense to represent the indemnified party in any action for which indemnification is sought (in which case the indemnifying party shall not thereafter be responsible for the fees and expenses of any separate counsel retained by the indemnified party or parties except as set forth below); provided, however, that such counsel shall be satisfactory to the indemnified party.  Notwithstanding the indemnifying party’s election to appoint counsel to represent the indemnified party in an action, the indemnified party shall have the right to employ separate counsel (including local counsel), and the indemnifying party shall bear the reasonable fees, costs and expenses of such separate counsel if (i) the use of counsel chosen by the indemnifying party to represent the indemnified party would present such counsel with a conflict of interest, (ii) the actual or potential defendants in, or targets of, any such action include both the indemnified party and the indemnifying party and the indemnified party shall have reasonably concluded that there may be legal defenses available to it and/or other indemnified parties which are different from or additional to those available to the indemnifying party, (iii) the indemnifying party shall not have employed counsel satisfactory to the indemnified party to represent the indemnified party within a reasonable time after notice of the institution of such action or (iv) the indemnifying party shall authorize the indemnified party to employ separate counsel at the expense of the indemnifying party.  An indemnifying party will not, without the prior written consent of the indemnified parties, settle or compromise or consent to the entry of any judgment with respect to any pending or threatened claim, action, suit or proceeding in respect of which indemnification or contribution may be sought hereunder (whether or not the indemnified parties are actual or potential parties to such claim or action) unless such settlement, compromise or consent (i) includes an unconditional release of each indemnified party from all liability arising out of such claim, action, suit or proceeding 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)                                 In the event that the indemnity provided in paragraph (a) or (b) of this Section 7 is unavailable to or insufficient to hold harmless an indemnified party for any reason, the Partnership Parties and each Manager, severally and not jointly, agrees to contribute to the aggregate losses, claims, damages and liabilities (including legal or other expenses reasonably

29

incurred in connection with investigating or defending same) (collectively “Losses”) to which the Partnership Parties and  such Manager may be subject in such proportion as is appropriate to reflect the relative benefits received by the Partnership Parties on the one hand and by such Manager on the other from the offering of the Units; provided, however, that in no case shall any Manager be responsible for any amount in excess of the underwriting discount or commission applicable to the Units purchased by such Manager hereunder. If the allocation provided by the immediately preceding sentence is unavailable for any reason, the Partnership Parties and each Manager, severally and not jointly, shall contribute in such proportion as is appropriate to reflect not only such relative benefits but also the relative fault of the Partnership Parties on the one hand and of such Manager on the other in connection with the statements or omissions which resulted in such Losses as well as any other relevant equitable considerations.  Benefits received by the Partnership Parties shall be deemed to be equal to the total gross proceeds from the offering less the total commissions received by such Manager, and benefits received by such Manager shall be deemed to be equal to the total commissions received by such Manager.  Relative fault shall be determined by reference to, among other things, whether any untrue or any alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information provided by the Partnership Parties on the one hand or such Manager on the other, the intent of the parties and their relative knowledge, access to information and opportunity to correct or prevent such untrue statement or omission.  The Partnership Parties and the Managers agree that it would not be just and equitable if contribution were determined by pro rata allocation or any other method of allocation which does not take account of the equitable considerations referred to above.  Notwithstanding the provisions of this Section 7(d), no Manager shall be required to contribute any amount in excess of the amount by which the total price at which the Units purchased by it and 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 any such untrue or alleged untrue statement or omission or alleged omission.  Notwithstanding the provisions of this paragraph (d), 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, each person who controls any Manager within the meaning of either the Securities Act or the Exchange Act and each affiliate, director, officer, employee and agent of any Manager shall have the same rights to contribution as the Managers, and each person who controls the Partnership Parties within the meaning of either the Securities Act or the Exchange Act, each officer of the Partnership Parties who shall have signed the Registration Statement and each director of the Partnership Parties shall have the same rights to contribution as the Partnership Parties, subject in each case to the applicable terms and conditions of this paragraph (d).

SECTION 8.  Representations, Warranties and Agreements to Survive Delivery.  All representations, warranties and agreements contained in this Agreement or in certificates of officers of the Partnership or any of its subsidiaries submitted pursuant hereto, shall remain operative and in full force and effect, regardless of any investigation made by or on behalf of the Managers or controlling person, or by or on behalf of the Partnership, and shall survive delivery of the Units to any Manager.

30

SECTION 9.  Termination of Agreement.

(a)                                 Termination by the Partnership.  Subject to the remaining terms of this Section 9, the Partnership shall have the right, by giving notice as hereinafter specified to terminate this Agreement as to any or all Managers in its sole discretion at any time after the date of this Agreement; provided, however, that with respect to any pending sale, through any 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.

(b)                                 Termination by any Manager.  Subject to the remaining terms of this Section 9, each Manager shall have the right, by giving notice as hereinafter specified to terminate its obligations under this Agreement in its sole discretion at any time after the date of this Agreement.

(c)                                  Automatic Termination.  Unless earlier terminated pursuant to this Section 9, this Agreement shall automatically terminate upon the issuance and sale of all of the Units through the Managers on the terms and subject to the conditions set forth herein with an aggregate sale price equal to the amount set forth in Section 1 of this Agreement.

(d)                                 Continued Force and Effect.  This Agreement shall remain in full force and effect unless terminated pursuant to Sections 9(a), (b) or (c) above or otherwise by mutual agreement of the parties.

(e)                                  Effectiveness of Termination.  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 such Manager or the Partnership, as the case may be.  If such termination shall occur prior to the Settlement Date for any sale of Units, such Units shall settle in accordance with the provisions of this Agreement.

(f)                                   Liabilities.  If this Agreement is terminated pursuant to this Section 9, such termination shall be without liability of any party to any other party except as provided in Section 5 hereof, and except that, in the case of any termination of this Agreement, Section 2, Section 7, Section 8 and Section 18 hereof shall survive such termination and remain in full force and effect.
