          1. Description of Units. The Partnership proposes to issue and sell through or to the Manager, as sales agent and/or principal, common units representing limited partner interests in the Partnership (“Common Units”), having an aggregate gross sales price to the public of up to $100,000,000 (the “Units”), from time to time during the term of this Agreement and on the terms set forth in Section 3 of this Agreement. For the avoidance of doubt, the term “Units” as used in this Agreement refers only to the Common Units to be sold pursuant to this Agreement. The Units are further described in the Prospectus referred to herein. For purposes of selling the Units through the Manager, the Partnership hereby appoints the Manager as exclusive agent of the Partnership for the purpose of soliciting purchases of the Units from the Partnership pursuant to this Agreement and the Manager agrees to use its reasonable efforts to solicit purchases of the Units on the terms and subject to the conditions stated herein. The Partnership agrees that whenever it determines to sell Units directly to the Manager as principal, it will enter into a separate agreement (each, a “Terms Agreement”) in substantially the form of Exhibit A hereto, relating to such sale in accordance with Section 3 of this Agreement. Certain terms used herein are defined in Section 19 hereof.

          The Partnership, Targa Resources GP LLC, a Delaware limited liability company and the general partner of the Partnership (the “General Partner”), and Targa Resources Operating LLC, a Delaware limited liability company and a wholly-owned subsidiary of the Partnership, are collectively referred to herein as the “Targa Parties.” The Partnership’s direct or indirect majority-owned subsidiaries are listed in Schedule I-A attached hereto and are referred to herein as the “Subsidiaries” (and collectively with the Partnership, the “Partnership Entities”); and the subsidiaries listed in Schedule I-B attached hereto are referred to herein as the “Material Subsidiaries.”

          2. Representations and Warranties. The Partnership represents and warrants to, and agrees with, the Manager at the Execution Time and on each such time the following

          3. Sale and Delivery of Units.

          (a) Sale of Units by Manager, as Sales Agent. Subject to the terms and conditions and in reliance upon the representations and warranties herein set forth, the Partnership agrees to issue and sell Units from time to time through the Manager, acting as sales agent, and the Manager agrees to use its reasonable efforts to sell, as sales agent for the Partnership, the Units on the following terms.

     (i) The Units are to be sold on a daily basis or otherwise as shall be agreed to by the Partnership and the 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” on Schedule III hereto, has instructed the Manager by telephone (confirmed promptly by electronic mail) to make such sales and (C) the Partnership has satisfied its obligations under Section 6 of this Agreement. The Partnership will designate the maximum amount of the Units to be sold by the Manager daily as agreed to by the Manager (in any event not in excess of the amount available for issuance under the Prospectus and the currently effective Registration Statement) and the minimum price per Unit at which such Units may be sold. Subject to the terms and conditions hereof, the Manager shall use its 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 market price for the

Partnership’s Common Units sold by the Manager under this Section 3(a) on the NYSE at the time of sale of such Units.

     (ii) The Partnership acknowledges and agrees that (A) there can be no assurance that the Manager will be successful in selling the Units, (B) the Manager will incur no 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 the Manager to use its reasonable efforts consistent with its normal trading and sales practices and applicable law and regulations to sell such Units as required under this Agreement, and (C) the Manager shall be under no obligation to purchase Units on a principal basis pursuant to this Agreement, except as otherwise specifically agreed by the Manager and the Partnership.

     (iii) The Partnership shall not authorize the issuance and sale of, and the Manager shall not be obligated to use its reasonable efforts to sell, any Units at a price lower than the minimum price therefor designated from time to time by the Board of Directors of the General Partner (the “Board”), a duly authorized committee thereof, or any individual to whom such authority has been duly and properly delegated by the Board or a duly authorized committee thereof, and notified to the Manager in writing. The Partnership or the Manager may, upon notice to the other party hereto by telephone (confirmed promptly by electronic mail), suspend or terminate the offering of the Units 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.

     (iv) The Manager 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 means of ordinary brokers’ transactions between members of the NYSE that qualify for delivery of a Prospectus to the NYSE in accordance with Rule 153 under the Act (such transactions are hereinafter referred to as “Continuous Offerings”) and (B) such other sales of the Units on behalf of the Partnership in its capacity as agent of the Partnership as shall be agreed by the Partnership and the Manager pursuant to a Terms Agreement.

     (v) The compensation to the Manager for sales of the Units with respect to which the Manager acts as sales agent under this Agreement shall be 2% of the gross sales price of the Units sold pursuant to this Section 3(a) and payable as described in the succeeding subsection (vi) below. The foregoing rate of compensation shall not apply when the Manager acts as principal, in which case the Partnership may sell Units to the Manager as principal at a price mutually agreed upon at the relevant Applicable Time pursuant to a Terms Agreement. The gross proceeds less the Manager’s commission shall constitute the net proceeds to the Company for such Units (the “Net Proceeds”). Payment of the Net Proceeds after further deduction for any transaction fees imposed by any governmental or self-regulatory organization in respect of such sales (the “Transaction Fees”), for Units sold by the Company on any Settlement Date shall

be made to the Company by federal funds wire transfer to the account of the Company against delivery of such Units to the Manager’s account, or an account of Manager’s designee, at The Depository Trust Company (“DTC”).

     (vi) The Manager shall provide written confirmation (which may be by facsimile or electronic mail) to the Partnership following the close of trading on the NYSE each day in which the Units are sold under this Section 3(a) setting forth the number of the Units sold on such day, the aggregate gross sales proceeds and the Net Proceeds to the Partnership, and the compensation payable by the Partnership to the Manager with respect to such sales. Such compensation shall be set forth and invoiced in periodic statements from the Manager to the Partnership, with payment to be made by the Partnership promptly after its receipt thereof.

     (vii) Settlement for sales of the Units pursuant to this Section 3(a) will occur on the third Business Day following the date on which such sales are made (each such day, a “Settlement Date”). On each Settlement Date, the Units sold through the Manager for settlement on such date shall be issued and delivered by the Partnership to the Manager against payment of the Net Proceeds for the sale of such Units. Settlement for all such Units shall be effected by free delivery of the Units to the Manager’s account at The Depository Trust Company (“DTC”) 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 Units on any Settlement Date, the Partnership shall (A) indemnify and hold the Manager harmless against any loss, claim or damage arising from or as a result of such default by the Partnership and (B) pay the Manager any commission to which it would otherwise be entitled absent such default. If the Manager breaches this Agreement by failing to deliver the Net Proceeds less any Transaction Fees to the Partnership on any Settlement Date for the Units delivered by the Partnership, the Manager will pay the Partnership interest based on the effective overnight federal funds rate on such unpaid amount less any compensation due to the Manager.

     (viii) At each Applicable Time, Settlement Date and Representation Date (as defined in Section 4(k)), the Partnership shall be deemed to have affirmed each representation and warranty contained in this Agreement as if such representation and warranty were made as of such date, but modified to relate to the Registration Statement, the Prospectus and the documents incorporated by reference therein, in each case as amended or supplemented as of such date. Any obligation of the Manager to use its reasonable efforts to sell the Units on behalf of the Partnership shall be subject to the continuing accuracy of the representations and warranties of the Partnership herein (as modified in the manner described above), to the performance by the Partnership of its obligations hereunder and to the continuing satisfaction of the additional conditions specified in Section 6 of this Agreement.

     (b) Sale of Units by Manager, as Principal. If the Partnership wishes to issue and sell the Units pursuant to this Agreement but other than as set forth in Section 3(a) 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. 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.

     (c) Terms Agreement. Each sale of the Units 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 Units to, and the purchase thereof by, the Manager. A Terms Agreement may also specify certain provisions relating to the reoffering of such Units by the Manager. The commitment of the Manager to purchase the Units pursuant to any Terms Agreement shall be deemed to have been made on the basis of the representations and warranties of the Partnership herein contained, but modified in the manner described in Section 3(a)(viii) hereof, and shall be subject to the terms and conditions herein set forth. Each Terms Agreement shall specify the number of the Units to be purchased by the Manager pursuant thereto, the price to be paid to the Partnership for such Units, any provisions relating to rights of, and default by, underwriters acting together with the Manager in the reoffering of the Units, and the time and date (each such time and date being referred to herein as a “Time of Delivery”) and place of delivery of and payment for such Units. Such Terms Agreement shall also specify any requirements for opinions of counsel, accountants’ letters and officers’ certificates pursuant to Section 6 of this Agreement and any other information or documents required by the Manager.

     (d) Limitations on Number and Amount of Units Sold. Under no circumstances shall the number and aggregate amount of the Units sold pursuant to this Agreement and any Terms Agreement exceed (i) the aggregate amount set forth in Section 1, (ii) the number of Common Units available for issuance under the currently effective Registration Statement or (iii) the number and aggregate amount of the Units authorized from time to time to be issued and sold under this Agreement by the Board, or a duly authorized committee thereof, and notified to the Manager in writing.

     (e) Regulation M Exemption. 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 Units, it shall promptly notify the other party and sales of the Units under this Agreement and any Terms Agreement shall be suspended until that or other exemptive provisions have been satisfied in the judgment of each party.

          4. Agreements. The Partnership covenants and agrees with the Manager that:

     (a) Filing of Amendment or Supplement. During any period when the delivery of a prospectus relating to the Units is required (including in circumstances where such requirement may be satisfied pursuant to Rule 172) to be delivered under the Act, the Partnership will not file any (i) amendment to the Registration Statement, (ii) supplement to the Prospectus or (iii) a Rule 462(b) Registration Statement relating to the Units (other than, in the case of clauses (i) and (ii) above, any amendment or supplement which does not relate to the sale of the Units and not including any reports or documents and any preliminary or definitive proxy or information statement required to be filed by the Partnership with the Commission in order to comply with the Exchange Act), unless the Partnership has furnished to the Manager a copy for its review prior to filing and will not file any such proposed amendment, supplement or Registration Statement to which the Manager reasonably objects, unless the Partnership shall have determined based upon the advice of counsel that such amendment, supplement or filing is required by law. The Partnership has properly completed the Prospectus, in a form approved by the Manager, and filed such Prospectus, as amended at the Execution Time, with the Commission pursuant to the applicable paragraph of Rule 424(b) by the Execution Time and will cause any supplement to the Prospectus to be properly completed in a form approved by the Manager, and will file such supplement with the Commission pursuant to the applicable paragraph of Rule 424(b) within the time period prescribed thereby and will provide evidence satisfactory to the Manager of such timely filing. The Partnership will promptly advise the Manager (i) when the Prospectus, and any supplement thereto, shall have been filed (if required) with the Commission pursuant to Rule 424(b) or when any Rule 462(b) Registration Statement relating to the Units shall have been filed with the Commission, (ii) when, during any period when the delivery of a prospectus (whether physically, deemed to be delivered pursuant to Rule 153 or through compliance with Rule 172 or any similar rule) is required under the Act in connection with the offering or sale of the Units, any amendment to the Registration Statement shall have been filed or become effective, (iii) of any request by the Commission or its staff for any amendment of the Registration Statement or any Rule 462(b) Registration Statement relating to the Units, or for any supplement to the Prospectus or for any additional information, (iv) of the issuance by the Commission of any stop order suspending the effectiveness of the Registration Statement or of any notice objecting to its use or the institution or threatening of any proceeding for that purpose, and (v) of the receipt by the Partnership of any notification with respect to the suspension of the qualification of the Units for sale in any jurisdiction or the institution or threatening of any proceeding for such purpose. The Partnership will use its commercially reasonable efforts to prevent the issuance of any such stop order or the occurrence of any such suspension or objection to the use of the Registration Statement and, upon such issuance, occurrence or notice of objection, to obtain as soon as possible the withdrawal of such stop order or relief from such occurrence or objection, including, if necessary, by filing an amendment to the Registration Statement or a new registration statement and using its commercially reasonable efforts to have such amendment or new registration statement declared effective as soon as practicable.

     (b) Notice of Material Changes. If, at any time on or after an Applicable Time but prior to the related Settlement Date or Time of Delivery, any event occurs as a result of which the Prospectus would include any 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 or the circumstances then prevailing not misleading, the Partnership will (i) notify promptly the Manager so that any use of the Prospectus may cease until it is amended or supplemented; (ii) amend or supplement the Prospectus to correct such statement or omission; and (iii) supply any amendment or supplement to the Manager in such quantities as the Manager may reasonably request.

     (c) Amendment of Registration Statement or Supplement of Prospectus. During any period when the delivery of a prospectus relating to the Units is required (including in circumstances where such requirement may be satisfied pursuant to Rule 172) to be delivered under the Act, any event occurs as a result of which the Prospectus as then supplemented would include any 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 at such time not misleading, or if it shall be necessary to amend the Registration Statement, file a new registration statement or supplement the Prospectus to comply with the Act or the Exchange Act or the respective rules thereunder, including in connection with use or delivery of the Prospectus, the Partnership promptly will (i) notify the Manager of any such event; (ii) prepare and file with the Commission, subject to the second sentence of paragraph (a) of this Section 4, an amendment or supplement or new registration statement which will correct such statement or omission or effect such compliance; (iii) use its commercially reasonable efforts to have any amendment to the Registration Statement or new registration statement declared effective as soon as practicable in order to avoid any disruption in use of the Prospectus; and (iv) supply any supplemented Prospectus to the Manager in such quantities as the Manager may reasonably request.

     (d) Reports to Unitholders. In accordance with Section 11(a) of the Act and Rule 158, the Partnership will make generally available to its security holders an earnings statement (which need not be audited) in reasonable detail covering the 12-month period beginning not later than the first day of the month next succeeding the month in which occurred the effective date (within the meaning of Rule 158) of the Registration Statement as soon as practicable after the end of such period.

     (e) Signed Copies of the Registration Statement and Copies of the Prospectus. The Partnership will furnish to the Manager and counsel for the Manager, upon request and without charge, one copy of the executed Registration Statement (including exhibits thereto) and, so long as delivery of a prospectus by the Manager or dealer may be required by the Act (including in circumstances where such requirement may be satisfied pursuant to Rule 172), as many copies of the Prospectus and any supplement thereto as the Manager may reasonably request.

     (f) Qualification of Units in Certain Jurisdictions. The Partnership will arrange, if necessary, for the qualification of the Units for sale under the laws of such jurisdictions as the Manager may designate and will maintain such qualifications in effect

so long as required for the distribution of the Units; 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.

     (g) No Issuer Free Writing Prospectus. Each of the Partnership and the Manager agree that it has not made and will not make any offer relating to the Units that would constitute an Issuer Free Writing Prospectus or that would otherwise constitute a “free writing prospectus” (as defined in Rule 405) required to be filed by the Partnership with the Commission or retained by the Partnership under Rule 433.

     (h) Limitations on Sale of Common Units. If sales of the Units have been made but not settled, or the Partnership has had outstanding with the Manager any instructions to sell the Units, in either case, within the prior three Business Days, the Partnership will not offer, sell, contract to sell, pledge, or otherwise dispose of, or enter into any transaction which is designed to, or might reasonably be expected to, result in the disposition (whether by actual disposition or effective economic disposition due to cash settlement or otherwise) by the Partnership or any affiliate of the Partnership or any person in privity with the Partnership or any affiliate of the Partnership, directly or indirectly, including the filing (or participation in the filing) of a registration statement with the Commission in respect of, or establish or increase a put equivalent position or liquidate or decrease a call equivalent position within the meaning of Section 16 of the Exchange Act, any Common Units or any securities convertible into, or exercisable, or exchangeable for, Common Units, or publicly announce an intention to effect any such transaction without (i) giving the Manager at least three Business Days’ prior written notice specifying the nature of the proposed transaction and the date of such proposed transaction and (ii) the Manager suspending acting under this Agreement for such period of time requested by the Partnership or as deemed appropriate by the Manager in light of the proposed transaction; provided, however, that (i) the Partnership may issue and sell Common Units pursuant to this Agreement or any Terms Agreement, (ii) the Partnership may issue and sell Common Units pursuant to any employee benefit plan of the Partnership in effect on or prior to the Execution Time, and (iii) the Partnership may issue Common Units issuable upon the conversion, vesting or exercise of securities or the exercise of warrants outstanding at the Execution Time.

     (i) Market Stabilization. The Partnership will not (i) take, directly or indirectly, any action designed to or that would constitute or that might reasonably be expected to cause or result in, under the Exchange Act or otherwise, stabilization or manipulation of the price of the Common Units to facilitate the sale or resale of the Units or (ii) sell, bid for, purchase or pay any person (other than as contemplated by this Agreement or any Terms Agreement) any compensation for soliciting purchases of the Units.

     (j) Notifications to Manager. The Partnership will, at any time during the term of this Agreement, as supplemented from time to time, advise the Manager immediately after it shall have received notice or obtained knowledge thereof, of any

information or fact that would alter or affect any opinion, certificate, letter and other document provided to the Manager pursuant to Section 6 herein.

     (k) Certificates. Upon commencement of the offering of the Units under this Agreement (and upon the recommencement of the offering of the Units under this Agreement following the termination of a suspension of sales hereunder), and each time that (i) the Registration Statement or the Prospectus shall be amended or supplemented (other than an amendment or supplement effected by the filing with the Commission of any document incorporated by reference therein, any prospectus supplement filed pursuant to Rule 424(b) pursuant to Section 4(a) hereof or a prospectus supplement relating solely to the offering of securities other than the Units), (ii) the Partnership shall file an Annual Report on Form 10-K or a Quarterly Report on Form 10-Q, (iii) the Units are delivered to the Manager as principal at the Time of Delivery pursuant to a Terms Agreement, or (iv) otherwise as the Manager may reasonably request (such commencement or recommencement date and each such date referred to in subsection (i), (ii), (iii) and (iv) herein, each a “Representation Date”), the Partnership shall furnish or cause to be furnished to the Manager forthwith a certificate dated and delivered on the Representation Date, in form satisfactory to the Manager to the effect that the statements contained in the certificate referred to in Section 6(d) hereof which were last furnished to the Manager are true and correct as of such Representation Date, as though made at and as of such time (except that such certificate shall state that such statements (including with respect to the representations and warranties contained herein) shall be deemed modified to incorporate the disclosures contained in the Registration Statement, the Prospectus and the documents incorporated by reference therein, in each case as amended or supplemented as of such date) or, in lieu of such certificate, a certificate of the same tenor as the certificate referred to in said Section 6(d), modified as described immediately above to the time of delivery of such certificate.

     (l) Opinion of Partnership Counsel. At each Representation Date, the Partnership shall furnish or cause to be furnished forthwith to the Manager and to counsel to the Manager a written opinion of Vinson & Elkins L.L.P., counsel to the Partnership (“Partnership Counsel”), dated as of such Representation Date, in form and substance satisfactory to the Manager, of the same tenor as the opinion referred to in Section 6(b) of this Agreement, but modified as necessary to relate to the Registration Statement and the Prospectus as amended and supplemented to the time of delivery of such opinion.

     (s) Acceptance of Offer to Purchase. Each acceptance by the Partnership of an offer to purchase the Units hereunder, and each execution and delivery by the Partnership

     (xii) No Conflicts. None of (i) the offering, issuance or sale by the Partnership of the Units, (ii) the execution, delivery and performance of this Agreement by the Partnership, or (iii) the consummation of the transactions contemplated by this Agreement, (A) constitutes or will constitute a violation of the Organizational Documents of the Partnership, the General Partner or the Material Subsidiaries, (B) conflicts or will conflict with or constitutes or will constitute a breach or violation of, or a default (or an event that, with notice or lapse of time or both, would constitute such a default) under any agreement or other instrument filed as an exhibit to the Registration Statement or any document incorporated by reference therein or the Partnership Credit Agreement or the TRI Credit Agreement, (C) violates or will violate the Delaware LP Act, the Delaware LLC Act, the laws of the State of Texas or federal law, (D) violates or will violate any order, judgment, decree or injunction of any court or governmental agency or other authority known to such counsel having jurisdiction over the Partnership, the General Partner or the Material Subsidiaries or any of their properties or assets in a proceeding to which any of them or their property is a party or (E) results or will result in the creation or imposition of any Lien pursuant to any agreement filed as an exhibit to the Registration Statement or any document incorporated by reference therein upon any property or assets of the Partnership, the General Partner or the Material Subsidiaries (other than Liens created pursuant to the Partnership Credit Agreement or the TRI Credit Agreement), which conflicts, breaches, violations, defaults or Liens, in the case of clauses (B), (C), (D) or (E), would reasonably be expected to have a Material Adverse Effect or a material adverse effect on the ability of the Partnership to consummate the transactions provided for in this Agreement; provided, however, that no opinion need be

expressed pursuant to this paragraph with respect to federal or state securities laws and other anti-fraud laws.

     (xiii) No Consents. No permit, consent, approval, authorization, order, registration, filing or qualification under the Delaware LP Act, the Delaware LLC Act, Texas law or federal law is required in connection with the offering, issuance or sale by the Partnership of the Units, the execution, delivery and performance of this Agreement by the Partnership, or the consummation of the transactions contemplated by this Agreement except (i) for such permits, consents, approvals and similar authorizations required under the Act, the Exchange Act, and state securities or “Blue Sky” laws, as to which such counsel need not express any opinion, (ii) for such consents which have been obtained or made, (iii) for such consents which, if not obtained, would not, individually or in the aggregate, reasonably be expected to have a Material Adverse Effect or (iv) as disclosed in the Prospectus.

     (xiv) Effectiveness of Registration Statement. The Registration Statement became effective under the Act on July 31, 2009; any required filing of the Prospectus, and any supplements thereto, pursuant to Rule 424(b) has been made in the manner and within the time period required by Rule 424(b); to the knowledge of such counsel, no stop order suspending the effectiveness of the Registration Statement or any notice objecting to its use has been issued and no proceedings for that purpose have been instituted or threatened.

     (xv) Form of Registration Statement and Prospectus. The Registration Statement, on the initial Effective Date, and the Prospectus, when filed with the Commission pursuant to Rule 424(b) and on the date of such opinion, were, on their face, appropriately responsive, in all material respects, to the requirements of the Act, except that in each case such counsel need express no opinion with respect to the financial statements or other financial and statistical data contained in or omitted from the Registration Statement or the Prospectus.

     (xvi) Description of Common Units. The statements included in the Registration Statement and Prospectus under the captions “Summary—The Offering,” “Description of our Common Units,” “The Partnership Agreement” and “Cash Distribution Policy” insofar as they purport to constitute summaries of the terms of the Common Units (including the Units), are accurate summaries of the terms of such Common Units in all material respects.

     (xvii) Descriptions and Summaries. The statements included in the Registration Statement under the captions “Cash Distribution Policy,” “The Partnership Agreement” and “Investment in Targa Resources Partners LP by Employee Benefit Plans” and under the caption “Certain Relationships and Related Transactions, and Director Independence,” in the Partnership’s Annual Report on Form 10-K for the year ended December 31, 2010 (“2010 Annual Report”) insofar as they purport to constitute summaries of the terms of federal or Texas statutes, rules or regulations or the Delaware LP Act or the Delaware LLC

Act, any legal and governmental proceedings or any contracts, constitute accurate summaries of the terms of such statutes, rules and regulations, legal and governmental proceedings and contracts in all material respects. The description of the federal statutes, rules and regulations set forth in the 2010 Annual Report under “Business—Regulation of Operations” and “Business—Environmental, Health and Safety Matters” constitute accurate summaries of the terms of such statutes, rules and regulations in all material respects.

     (xviii) Tax Opinion. The opinion of Vinson & Elkins L.L.P. that is filed as Exhibit 8.1 to the Registration Statement is confirmed and the Manager may rely upon such opinion as if it were addressed to them.

     (xix) Investment Company. The Partnership is not, and after giving effect to the offering and sale of the Units and the application of the proceeds thereof as described in the Prospectus, will not be, an “investment company” as defined in the Investment Company Act.

     In rendering such opinion, such counsel may (i) rely in respect of matters of fact upon the representations and warranties in this Agreement, certificates of officers and employees of the Targa Parties and upon information obtained from public officials to the extent such counsel deems reasonable, (ii) assume that all documents submitted to such counsel as originals are authentic, that all copies submitted to such counsel conform to the originals thereof, and that the signatures on all documents examined by such counsel are genuine, (iii) state that its opinion is limited to matters governed by federal law and the Delaware LP Act, Delaware LLC Act and the laws of the State of Texas, and (iv) state that they express no opinion with respect to (A) any permits to own or operate any real or personal property or (B) state or local taxes or tax statutes to which any of the limited partners of the Partnership or any of the Material Subsidiaries may be subject. Such counsel may exclude any non-wholly-owned entities from its opinion regarding ownership of Material Subsidiaries.

     In addition, such counsel shall state that they have participated in conferences with officers and other representatives of the Partnership and the General Partner, the independent registered public accountants of the Partnership and the Manager’s representatives, at which the contents of the Registration Statement and the Prospectus and related matters were discussed, and although such counsel has not independently verified, is not passing upon, and is not assuming any responsibility for the accuracy, completeness or fairness of the statements contained in, the Registration Statement and the Prospectus (except to the extent specified in the foregoing opinion), based on the foregoing, no facts have come to such counsel’s attention that lead such counsel to believe that:

          (A) the Registration Statement, as of the most recent Effective Date, contained an untrue statement of a material fact or omitted to state a material fact required to be stated therein or necessary to make the statements therein not misleading, or

          (B) the Prospectus, as of its date and as of the date of such opinion, contained or contains an untrue statement of a material fact or omitted or omits to state a material fact necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading;

     it being understood that such counsel expresses no statement or belief with respect to (i) the financial statements and related schedules, including the notes and schedules thereto and the auditor’s reports thereon, or any other financial and accounting information, included in, or incorporated by reference in, the Registration Statement or the Prospectus, and (ii) representations and warranties and other statements of fact included in the exhibits to the Registration Statement or any document incorporated by reference therein.

     (c) The Manager shall have received from Baker Botts L.L.P., counsel for the Manager, on every Representation Date, its opinion, dated as of such date and addressed to the Manager, with respect to the issuance and sale of the Units, the Registration Statement, the Prospectus (together with any supplement thereto) and other related matters as the Manager may reasonably require, and the Partnership shall have furnished to such counsel such documents as they request for the purpose of enabling them to pass upon such matters.

     (d) The Partnership shall have furnished to the Manager, on every Representation Date, a certificate of the Partnership, signed on behalf of the Partnership by the Chief Executive Officer or Chief Financial Officer of the General Partner, dated as of such date, to the effect that the signers of such certificate have carefully examined the Registration Statement and the Prospectus and any amendment or supplement thereto and this Agreement and that:

     (i) the representations and warranties of the Partnership in this Agreement are true and correct on and as of such date with the same effect as if made on such date and the Partnership has complied with all the agreements and satisfied all the conditions on its part to be performed or satisfied at or prior to such date;

     (ii) no stop order suspending the effectiveness of the Registration Statement or any notice objecting to its use has been issued and no proceedings for that purpose have been instituted or, to the Partnership’s knowledge, threatened; and

     (iii) since the date of the most recent financial statements included in the Prospectus, there has been no Material Adverse Effect, except as set forth in or contemplated in the Prospectus.

     (e) The Partnership shall have requested and caused PricewaterhouseCoopers LLP to have furnished to the Manager, on every date specified in Section 4(n) hereof and to the extent requested by the Manager in connection with any offering of the Units, letters (which may refer to letters previously delivered to the Manager), dated as of such

date, in form and substance satisfactory to the Manager containing statements and information of the type ordinarily included in accountants’ “comfort letters” to underwriters with respect to the financial statements and certain financial information contained in, or incorporated by reference in, the Registration Statement and the Prospectus.

     (f) Between the Execution Time and any Time of Delivery, there shall not have been (i) any change or decrease specified in the letter or letters referred to in paragraph (e) of this Section 6 or (ii) any change, or any development involving a prospective change, in or affecting the condition (financial or otherwise), earnings, business or properties of the Partnership Entities taken as a whole, whether or not arising from transactions in the ordinary course of business, except as set forth in or contemplated in the Prospectus (exclusive of any amendment or supplement thereto) the effect of which, in any case referred to in clause (i) or (ii) above, is, in the sole judgment of the Manager, so material and adverse as to make it impractical or inadvisable to proceed with the offering or delivery of the Units as contemplated by the Registration Statement (exclusive of any amendment thereof) and the Prospectus (exclusive of any amendment or supplement thereto).

     (g) Between the Execution Time and any Time of Delivery, there shall not have been any decrease in the rating of any of the Partnership’s debt securities by any “nationally recognized statistical rating organization” (as defined for purposes of Rule 436(g) under the Act) or any notice given of any intended or potential decrease in any such rating or of a possible change in any such rating that does not indicate the direction of the possible change.

     (h) FINRA shall not have raised any objection with respect to the fairness and reasonableness of the terms and arrangements under this Agreement or any Terms Agreement.

     (i) The Units shall have been listed and admitted and authorized for trading on the NYSE, and satisfactory evidence of such actions shall have been provided to the Manager.

     (j) The Partnership shall have furnished to the Manager at each Representation Date such further information, certificates and documents as the Manager may reasonably request.

          If any of the conditions specified in this Section 6 shall not have been fulfilled when and as provided in this Agreement, or if any of the opinions and certificates mentioned above or elsewhere in this Agreement shall not be reasonably satisfactory in form and substance to the Manager and counsel for the Manager, this Agreement and all obligations of the Manager hereunder may be canceled at, or at any time prior to, any Settlement Date or Time of Delivery, as applicable, by the Manager. Notice of such cancellation shall be given to the Partnership in writing or by telephone or facsimile confirmed in writing.

          The documents required to be delivered by this Section 6 shall be delivered at the office of Baker Botts L.L.P., counsel for the Manager, at 2001 Ross Avenue, Dallas, Texas 75201, or electronically if agreed to by the parties, on each such date as provided in this Agreement.

          7. Indemnification and Contribution.

     (a) The Partnership agrees to indemnify and hold harmless the Manager, the directors, officers, employees and agents and affiliates of the Manager and each person who controls the Manager within the meaning of either the Act or the Exchange Act against any and all losses, claims, damages, expenses or liabilities, joint or several, to which they or any of them may become subject under the Act, the Exchange Act or other federal or state statutory law or regulation, at common law or otherwise, insofar as such losses, claims, damages, expenses or liabilities (or actions in respect thereof) arise out of or are based upon any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement, the Base Prospectus, the Prospectus Supplement, the Prospectus or in any amendment thereof or supplement thereto, 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 agrees to reimburse each such indemnified party, as incurred, for any legal or other expenses reasonably incurred by them in connection with investigating, preparing for or defending any such loss, claim, damage, liability or action; provided, however, that the Partnership will not be liable in any such case to the extent that any such loss, claim, damage, expense 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 by or on behalf of the Manager specifically for inclusion therein. This indemnity agreement will be in addition to any liability which the Partnership may otherwise have.

     (b) The Manager agrees to indemnify and hold harmless the Partnership, each of the General Partner’s directors and officers who signs the Registration Statement, and each person who controls the Partnership within the meaning of either the Act or the Exchange Act, to the same extent as the foregoing indemnity from the Partnership to the Manager, but only with reference to written information relating to the Manager furnished to the Partnership by or on behalf of the Manager specifically for inclusion in the documents referred to in the foregoing indemnity. This indemnity agreement will be in addition to any liability which the 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 reasonably 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 reasonably 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 includes an unconditional release of each indemnified party from all liability arising out of such claim, action, suit or proceeding and 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), (b) or (c) of this Section 7 is unavailable to or insufficient to hold harmless an indemnified party for any reason, the Partnership and the Manager agree to contribute to the aggregate losses, claims, damages and liabilities (including legal or other expenses reasonably incurred in connection with investigating or defending the same) (collectively “Losses”) to which the Partnership and the Manager may be subject in such proportion as is appropriate to reflect the relative benefits received by the Partnership, on the one hand, and by the Manager, on the other, from the offering of the Units; provided, however, that in no case shall the Manager be responsible for any amount in excess of the compensation to the Manager for sales of the Units hereunder. If the allocation provided by the immediately preceding sentence is unavailable for any reason, the Partnership and the Manager severally shall contribute in such proportion as is appropriate to reflect not only such relative benefits but also the relative fault of the Partnership on the one hand and of the 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 shall be deemed to be equal to the total net proceeds from the offering of the Units purchased under this Agreement (before deducting expenses) received by the Partnership, as determined by this Agreement or any applicable Terms Agreement, and benefits

received by the Manager shall be deemed to be equal to the total compensation received by the Manager with respect to the Units purchased under this Agreement, in each case as determined by this Agreement or any applicable Terms Agreement. 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 on the one hand or by or on behalf of the 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 and the Manager 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 paragraph (d), 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. For purposes of this Section 7, each person who controls the Manager within the meaning of either the Act or the Exchange Act and each director, officer, employee and agent of the Manager shall have the same rights to contribution as the Manager, and each person who controls the Partnership within the meaning of either the Act or the Exchange Act, each officer of the General Partner, who shall have signed the Registration Statement and each director of the General Partner shall have the same rights to contribution as the Partnership, subject in each case to the applicable terms and conditions of this paragraph (d) to collect such amounts from the Partnership, except in the event that the Partnership commences or becomes subject to any bankruptcy, liquidation, reorganization, moratorium or other proceeding providing protection from creditors generally.

          8. Termination.

          (a) The Partnership 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 Units 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 Units have been sold through the Manager for the Partnership, then Section 4(s) 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 Sections 2, 5, 7, 9, 10, 11, 12, 13, 15 and 16 of this Agreement shall remain in full force and effect notwithstanding such termination.

          (b) The Manager shall have the right, by giving written notice as hereinafter specified, to terminate 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 be without liability of any party to any other party except that the provisions of Sections 2, 5, 7, 9, 10, 11, 12, 13, 15 and 16 of this Agreement shall remain in full force and effect notwithstanding such termination.

          (c) This Agreement shall remain in full force and effect unless terminated pursuant to Sections 8(a) or (b) 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 Sections 2, 5, 7 and 9 shall remain in full force and effect.

          (d) 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 or Time of Delivery for any sale of the Units, such sale shall settle in accordance with the provisions of Section 3(a)(vii) of this Agreement.

          (e) In the case of any purchase of Units by the Manager pursuant to a Terms Agreement, the obligations of the Manager pursuant to such Terms Agreement shall be subject to termination, in the absolute discretion of the Manager, by notice given to the Partnership prior to the Time of Delivery relating to such Units, if at any time prior to such delivery and payment (i) trading in the Partnership’s Common Units shall have been suspended by the Commission or the NYSE, (ii) trading in securities generally on the NYSE shall have been suspended or limited or minimum prices shall have been established on such exchange, (iii) a banking moratorium shall have been declared either by federal or New York State authorities or a material disruption in commercial banking or securities settlement or clearance services in the United States shall have occurred, or (iv) there shall have occurred any outbreak or escalation of hostilities, declaration by the United States of a national emergency or war, or other calamity or crisis the effect of which on financial markets is such as to make it, in the sole judgment of the Manager, impractical or inadvisable to proceed with the offering or delivery of the Units as contemplated by the Prospectus.

          9. Representations and Indemnities to Survive. The respective agreements, representations, warranties, indemnities and other statements of the Partnership or the General Partner’s 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 made by or on behalf of the Manager or the Partnership or any of the officers, directors, employees, agents or controlling persons referred to in Section 7 hereof, and will survive delivery of and payment for the Units. The provisions of Section 7 shall survive the termination or cancellation of this Agreement.

          10. Notices. All communications hereunder will be in writing and effective only on receipt, and, if sent to the Manager, will be mailed, delivered or telefaxed to Citigroup Global Markets Inc., General Counsel (fax no.: (212) 816-7912) and confirmed to it at Citigroup Global Markets Inc., 388 Greenwich Street, New York, New York, 10013, Attention: General Counsel; or, if sent to the Partnership, will be mailed, delivered or telefaxed to Targa Resources Partners LP and confirmed to it at 1000 Louisiana, Suite 4300, Houston, Texas 77002, attention of Paul W.

          11. Successors. This Agreement will inure to the benefit of and be binding upon the parties hereto and their respective successors and the officers, directors, employees, agents and controlling persons referred to in Section 7 hereof, and no other person will have any right or obligation hereunder.

          12. No Fiduciary Duty. The Partnership hereby acknowledges that (a) the purchase and sale of the Units pursuant to this Agreement is an arm’s-length commercial transaction between the Partnership, on the one hand, and the Manager and any affiliates through which it may be acting, on the other, (b) the Manager is acting solely as sales agent and/or principal in connection with the purchase and sale of the Units and not as a fiduciary of the Partnership, and (c) the Partnership’s engagement of the Manager in connection with the offering and the process leading up to the offering is as independent contractors and not in any other capacity. Furthermore, the Partnership agrees that it is solely responsible for making its own judgments in connection with the offering (irrespective of whether the Manager has advised or is currently advising the Partnership on related or other matters).
