     (d) The Representatives shall have received from Baker Botts L.L.P., counsel for the Underwriters, such opinion or opinions, dated the Closing Date and addressed to the Representatives, with respect to the issuance and sale of the Units, the Registration Statement, the Disclosure Package, the Prospectus (together with any supplement thereto) and other related matters as the Representatives may reasonably require, and the Targa Parties shall have furnished to such counsel such documents as they request for the purpose of enabling them to pass upon such matters.
     (e) The Targa Parties shall have furnished to the Representatives 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 the Closing Date, to the effect that

36


 

the signers of such certificate have examined the Registration Statement, the Disclosure Package, the Prospectus and any amendment or supplement thereto, as well as each electronic road show used in connection with the offering of the Units, and this Agreement and that:
     (i) the representations and warranties of the Targa Parties in this Agreement are true and correct on and as of the Closing Date with the same effect as if made on the Closing 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 the Closing 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 Disclosure Package and the Prospectus, there has been no Material Adverse Effect, except as set forth in or contemplated in the Disclosure Package and the Prospectus.
     (f) The Targa Parties shall have requested and caused PricewaterhouseCoopers LLP to have furnished to the Representatives, at the Execution Time and at the Closing Date, letters, dated respectively as of the Execution Time and as of the Closing Date, in form and substance satisfactory to the Representatives and PricewaterhouseCoopers LLP, confirming that they are an independent registered public accounting firm within the meaning of the Act and the Exchange Act and the applicable rules and regulations thereunder, adopted by the Commission and the Public Company Accounting Oversight Board (United States) (“PCAOB”),and that they have performed a review of the unaudited interim financial information of Targa North Texas LP for the nine-month period ended September 30, 2006 and as of September 30, 2006, in accordance with Statement on Auditing Standards No. 100 and stating in effect that:
     (i) in their opinion the audited financial statement of the Partnership as of October 23, 2006, the audited financial statement of Targa Resources GP LLC as of October 23, 2006, and the audited combined financial statements of Targa North Texas LP as of December 31, 2005 and 2004 and for the two months ended December 31, 2005, for the ten months ended October 31, 2005, and for each of the two years in the period ended December 31, 2004, included in the Registration Statement and reported on by them comply as to form in all material respects with the applicable accounting requirements of the Act and the related rules and regulations adopted by the Commission;
     (ii) on the basis of a reading of the latest unaudited financial statements of Targa North Texas LP included in the Registration Statement; their limited review, in accordance with standards established

37


 

under Statement on Auditing Standards No. 100, of the unaudited interim financial statements for the nine month period ended September 30, 2006 and as of September 30, 2006; carrying out certain specified procedures (but not an examination in accordance with generally accepted auditing standards) which would not necessarily reveal matters of significance with respect to the comments set forth in such letter; a reading of the minutes of the meetings of the partners and the Board of Directors (and its audit and compensation committees) of the Partnership, the General Partner, Targa North Texas LP, Targa Resources Investments Inc., and Targa Resources Inc. since December 31, 2005 through a specified date not more than three days prior to the date of the letter; and inquiries of certain officials who have responsibility for financial and accounting matters of Targa North Texas LP as to transactions and events subsequent to September 30, 2006 and regarding the specific items for which representations are requested below, nothing came to their attention as a result of the foregoing procedures that caused them to believe that:
     (1) the unaudited interim financial statements of Targa North Texas LP for the nine months ended September 30, 2006 and as of September 30, 2006 included in the Registration Statement do not comply as to form in all material respects with the applicable accounting requirements of the Act and with the related rules and regulations adopted by the Commission with respect to registration statements on Form S-1; and said unaudited financial statements are not in conformity with generally accepted accounting principles applied on a basis substantially consistent with that of the audited financial statements included in the Registration Statement;
     (2) with respect to the period subsequent to September 30, 2006, there was any increase, at a specified date (this paragraph (2) being included in said letter only if such date is no later than February 11, 2007) not more than three days prior to the date of the letter, in the long-term debt of Targa North Texas LP as compared with the amounts shown on the September 30, 2006 unaudited combined balance sheet included in the Registration Statement, or for the period from the date of the latest statement of operations included in the Registration Statement to such specified date there were any decreases, as compared with the corresponding period in the preceding year in total operating revenues of Targa North Texas LP, except in all instances for decreases set forth in such letter, in which case the Partnership shall provide written explanation as to the significance thereof unless said explanation is not deemed necessary by the Representatives; or
     (3) any material modifications should be made to the unaudited interim financial statements of Targa North Texas LP

38


 

for the nine-month period ended September 30, 2006 included in the Registration Statement for them to be in conformity with generally accepted accounting principles; or
     (iii) they have performed certain other specified procedures as a result of which they determined that certain information of an accounting or financial nature (which is limited to accounting or financial information obtained from the general accounting records of the Partnership, the General Partner, Targa North Texas LP, or Targa Resources Inc., which are subject to control over financial reporting or which has been derived directly from such accounting records) set forth in the Registration Statement, agrees with the accounting records of the Partnership, the General Partner, Targa North Texas LP, or Targa Resources Inc., or computations made therefrom, excluding any questions of legal interpretation; and
     (iv) on the basis of a reading of the unaudited pro forma condensed balance sheet of the Partnership as of September 30, 2006, and the unaudited pro forma condensed combined income statements for the year ended December 31, 2005 and for the nine months ended September 30, 2006, included in the Registration Statement (the “pro forma financial statements”); inquiries of certain officials of the Partnership who have responsibility for financial and accounting matters; and proving the arithmetic accuracy of the application of the pro forma adjustments to the historical amounts in the pro forma condensed financial statements, nothing came to their attention which caused them to believe that the unaudited pro forma condensed financial statements of the Partnership included in the Registration Statement do not comply as to form in all material respects with the applicable accounting requirements of Rule 11-02 of Regulation S-X or that the pro forma adjustments have not been properly applied to the historical amounts in the compilation of such statements.
     References to the Prospectus in this paragraph (e) include any supplement thereto at the date of the letter.
     (g) Subsequent to the Execution Time or, if earlier, the dates as of which information is given in the Registration Statement (exclusive of any amendment thereof) and the Prospectus (exclusive of any amendment or supplement thereto), there shall not have been (i) any change or decrease specified in the letter or letters referred to in paragraph (f) 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 Disclosure Package and the Prospectus the effect of which, in any case referred to in clause (i) or (ii) above, is, in the sole judgment of the Representatives, so material and adverse as to make it impractical or inadvisable to proceed with the

39


 

offering or delivery of the Units as contemplated by the Registration Statement (exclusive of any amendment thereof), the Disclosure Package and the Prospectus (exclusive of any amendment or supplement thereto).
     (h) Prior to the Closing Date, the Targa Parties shall have furnished to the Representatives such further information, certificates and documents as the Representatives may reasonably request.
     (i) Subsequent to the Execution Time, there shall not have been any decrease in the rating of any of the Targa Parties’ 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.
     (j) The Units shall have been listed and admitted and authorized for trading on the Nasdaq Global Market, and satisfactory evidence of such actions shall have been provided to the Representatives.
     (k) At the Execution Time, the Targa Parties shall have furnished to the Representatives a letter substantially in the form of Exhibit A hereto from each of the TGPI and TLPI and each officer and director of the General Partner.
     (l) The Targa Parties shall have furnished to the Representatives evidence satisfactory to the Representatives that each of the Transactions shall have occurred or will occur as of the Closing Date, including the concurrent closing of the new credit facility pursuant to the Credit Agreement, in each case as described in the Disclosure Package and the Prospectus without modification, change or waiver, except for such modifications, changes or waivers as have been specifically identified to the Representatives and which, in the judgment of the Representatives, do not make it impracticable or inadvisable to proceed with the offering and delivery of the Units on the Closing Date on the terms and in the manner contemplated in the Disclosure Package and the Prospectus.
          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 Representatives and counsel for the Underwriters, this Agreement and all obligations of the Underwriters hereunder may be canceled at, or at any time prior to, the Closing Date by the Representatives. 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 Underwriters, at 910 Louisiana, Houston, Texas 77002, on the Closing Date.
          7. Reimbursement of Underwriters’ Expenses. If the sale of the Units provided for herein is not consummated because any condition to the obligations of the Underwriters set forth in Section 6 hereof is not satisfied, because of any termination pursuant to

40


 

Section 10(i) hereof or because of any refusal, inability or failure on the part of the Targa Parties to perform any agreement herein or comply with any provision hereof other than by reason of a default by any of the Underwriters, the Targa Parties will reimburse the Underwriters severally through Citigroup Global Markets Inc. on demand for all out-of-pocket expenses (including reasonable fees and disbursements of counsel) that shall have been incurred by them in connection with the proposed purchase and sale of the Units.
          8. Indemnification and Contribution.
     (a) Each of Targa, the General Partner, the Partnership and the Operating Partnership agrees, jointly and severally, to indemnify and hold harmless each Underwriter, the directors, officers, employees and agents of each Underwriter and each person who controls any Underwriter within the meaning of either the 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 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 any untrue statement or alleged untrue statement of a material fact contained in the registration statement for the registration of the Units as originally filed or in any amendment thereof, or in any Preliminary Prospectus, the Prospectus or any Issuer Free Writing Prospectus or in any amendment thereof or supplement thereto or any other “issuer information” filed or required to be filed pursuant to Rule 433(d) under the Act, or arise out of or are based upon the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein 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 Targa, the General Partner, the Partnership and the Operating Partnership will not be liable in any such case to the extent that any such loss, claim, damage or liability arises out of or is based upon 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 Targa Parties by or on behalf of any Underwriter through the Representatives specifically for inclusion therein; provided, further, that prior to any Underwriter, director, officer, employee or agent of any Underwriter or any person who controls any Underwriter within the meaning of either the Act or the Exchange Act seeking any payment or reimbursement from Targa pursuant to this Section 8(a), such person shall do so only if and to the extent the Partnership Entities have not timely made such payments or reimbursement and such person has used commercially reasonable best efforts to collect such amounts from the General Partner, the Partnership and the Operating Partnership, except in the event that the General Partner, the Partnership and the Operating Partnership commences or becomes subject to any bankruptcy, liquidation, reorganization, moratorium or other proceeding providing protection from creditors generally. This indemnity agreement will be in addition to any liability which the General Partner, the Partnership or the Operating Partnership may otherwise have.
     (b) Each Underwriter severally and not jointly agrees to indemnify and hold harmless each of Targa, the General Partner, the Partnership and the Operating

41


 

Partnership, each of the General Partner’s directors and officers who sign the Registration Statement, and each person who controls Targa, the General Partner, the Partnership or the Operating Partnership within the meaning of either the Act or the Exchange Act, to the same extent as the foregoing indemnity from Targa, the General Partner, the Partnership and the Operating Partnership to each Underwriter, but only with reference to written information relating to such Underwriter furnished to the Targa Parties by or on behalf of such Underwriter through the Representatives specifically for inclusion in the documents referred to in the foregoing indemnity. This indemnity agreement will be in addition to any liability which any Underwriter may otherwise have. Each Targa Party acknowledges that, under the heading “Underwriting,” (i) the sentences related to concessions and reallowances and (ii) the paragraphs related to stabilization, syndicate covering transactions, penalty bids in the Preliminary Prospectus and the Prospectus and electronic delivery of the Prospectus, constitute the only information furnished in writing by or on behalf of the several Underwriters for inclusion in the Preliminary Prospectus, the Prospectus and any Issuer Free Writing Prospectus.
     (c) Each of Targa, the General Partner, the Partnership and the Operating Partnership agrees, jointly and severally, to indemnify and hold harmless UBS Securities LLC, the directors, officers, employees and agents of UBS Securities LLC and each person, who controls UBS Securities LLC within the meaning of either the Act or the Exchange Act (“UBS Entities”), from and against any and all losses, claims, damages and liabilities to which they may become subject under the Act, the Exchange Act or other Federal or state statutory law or regulation, at common law or otherwise (including, without limitation, any legal or other expenses reasonably incurred in connection with defending or investigating any such action or claim), insofar as such losses, claims damages or liabilities (or actions in respect thereof) (i) arise out of or are based upon any untrue statement or alleged untrue statement of a material fact contained in the prospectus wrapper material prepared by or with the consent of any of the Targa Parties for distribution in foreign jurisdictions in connection with the Directed Unit Program attached to the Prospectus, any preliminary prospectus or any Issuer Free Writing Prospectus, 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 statement therein, when considered in conjunction with the Prospectus or any applicable preliminary prospectus, not misleading; (ii) caused by the failure of any Participant to pay for and accept delivery of the securities which immediately following the Effective Date of the Registration Statement, were subject to a properly confirmed agreement to purchase; or (iii) related to, arising out of, or in connection with the Directed Unit Program, except that this clause (iii) shall not apply to the extent that such loss, claim, damage or liability is finally judicially determined to have resulted primarily from the gross negligence or willful misconduct of the UBS Entities; provided, that prior to any UBS Entity seeking any payment or reimbursement from Targa pursuant to this Section 8(c), such UBS Entity shall do so only if and to the extent the Partnership Entities have not timely made such payments or reimbursement and such person has used commercially reasonable best efforts to collect from the General Partner, the Partnership and the Operating Partnership, except in the event that the General Partner, the Partnership and the Operating Partnership commences or becomes subject to any

42


 

bankruptcy, liquidation, reorganization, moratorium or other proceeding providing protection from creditors generally.
     (d) Promptly after receipt by an indemnified party under this Section 8 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 8, 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), (b) or (c) 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), (b) or (c) 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. Notwithstanding anything contained herein to the contrary, if indemnity may be sought pursuant to Section 8(c) hereof in respect of such action or proceeding, then in addition to such separate firm for the indemnified parties, the indemnifying party shall be liable for the reasonable fees and expenses of not more than one separate firm (in addition to any local counsel) for UBS Securities LLC, the directors, officers, employees and agents of UBS Securities LLC, and all persons, if any, who control UBS Securities LLC within the

43


 

meaning of either the Act or the Exchange Act for the defense of any losses, claims, damages and liabilities arising out of the Directed Unit Program.
     (e) In the event that the indemnity provided in paragraph (a), (b) or (c) of this Section 8 is unavailable to or insufficient to hold harmless an indemnified party for any reason, Targa, the General Partner, the Partnership, the Operating Partnership and the Underwriters severally 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 Targa, the General Partner, the Partnership and the Operating Partnership and one or more of the Underwriters may be subject in such proportion as is appropriate to reflect the relative benefits received by Targa, the General Partner, the Partnership and the Operating Partnership, on the one hand, and by the Underwriters, on the other, from the offering of the Units, provided, however, that (i) prior to any such indemnified party seeking any payment or reimbursement from Targa pursuant to this Section 8(e), such person shall do so only if and to the extent the Partnership Entities have not timely made such payments or reimbursement and such person has used commercially reasonable best efforts to collect such amounts from the General Partner, the Partnership and the Operating Partnership, except in the event that the General Partner, the Partnership and the Operating Partnership commences or becomes subject to any bankruptcy, liquidation, reorganization, moratorium or other proceeding providing protection from creditors generally and (ii) in no case shall any Underwriter (except as may be provided in any agreement among underwriters relating to the offering of the Units) be responsible for any amount in excess of the underwriting discount or commission applicable to the Units purchased by such Underwriter hereunder. If the allocation provided by the immediately preceding sentence is unavailable for any reason, Targa, the General Partner, the Partnership and the Operating Partnership and the Underwriters severally shall contribute in such proportion as is appropriate to reflect not only such relative benefits but also the relative fault of Targa, the General Partner, the Partnership and the Operating Partnership, on the one hand, and of the Underwriters, on the other, in connection with the statements or omissions which resulted in such Losses as well as any other relevant equitable considerations; provided, however, that prior to any such indemnified party seeking any payment or reimbursement from Targa pursuant to this Section 8(e), such person shall do so only if and to the extent the Partnership Entities have not timely made such payments or reimbursement and such person has used commercially reasonable best efforts to collect such amounts from the General Partner, the

44


 

Partnership and the Operating Partnership, except in the event that the General Partner, the Partnership and the Operating Partnership commences or becomes subject to any bankruptcy, liquidation, reorganization, moratorium or other proceeding providing protection from creditors generally. Benefits received by Targa, the General Partner, the Partnership and the Operating Partnership shall be deemed to be equal to the total net proceeds from the offering (before deducting expenses) received by it, and benefits received by the Underwriters shall be deemed to be equal to the total underwriting discounts and commissions, in each case as set forth on the cover page of the Prospectus. 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 Targa, the General Partner, the Partnership and the Operating Partnership, on the one hand, or the Underwriters, 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. Targa, the General Partner, the Partnership and the Operating Partnership and the Underwriters 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 (e), 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 8, each person who controls an Underwriter within the meaning of either the Act or the Exchange Act and each director, officer, employee and agent of an Underwriter shall have the same rights to contribution as such Underwriter, and each person who controls Targa, the General Partner, the Partnership or the Operating Partnership within the meaning of either the Act or the Exchange Act, each officer of the any of Targa, the General Partner, the Partnership or the Operating Partnership who shall have signed the Registration Statement and each director of any of Targa, the General Partner, the Partnership or the Operating Partnership shall have the same rights to contribution as the Targa Parties, subject in each case to the applicable terms and conditions of this paragraph (e) to collect such amounts from the General Partner, the Partnership and the Operating Partnership, except in the event that the General Partner, the Partnership and the Operating Partnership commences or becomes subject to any bankruptcy, liquidation, reorganization, moratorium or other proceeding providing protection from creditors generally.
          9. Default by an Underwriter. If any one or more Underwriters shall fail to purchase and pay for any of the Units agreed to be purchased by such Underwriter or Underwriters hereunder and such failure to purchase shall constitute a default in the performance of its or their obligations under this Agreement, the remaining Underwriters shall be obligated severally to take up and pay for (in the respective proportions which the number of Units set forth opposite their names in Schedule I hereto bears to the aggregate number of Units set forth opposite the names of all the remaining Underwriters) the Units which the defaulting Underwriter or Underwriters agreed but failed to purchase; provided, however, that in the event that the aggregate number of Units which the defaulting Underwriter or Underwriters agreed but failed to purchase shall exceed 10% of the aggregate number of Units set forth in Schedule I hereto, the remaining Underwriters shall have the right to purchase all, but shall not be under any obligation to purchase any, of the Units, and if such nondefaulting Underwriters do not purchase all the Units, this Agreement will terminate without liability to any nondefaulting Underwriter or the Targa Parties. In the event of a default by any Underwriter as set forth in this Section 9, the Closing Date shall be postponed for such period, not exceeding five Business Days, as the Representatives shall determine in order that the required changes in the Registration Statement and the Prospectus or in any other documents or arrangements may be effected. Nothing contained in this Agreement shall relieve any defaulting Underwriter of its liability, if any, to the Targa Parties and any nondefaulting Underwriter for damages occasioned by its default hereunder.

45


 

          10. Termination. This Agreement shall be subject to termination in the absolute discretion of the Representatives, by notice given to the Partnership prior to delivery of and payment for the Units, if at any time prior to such delivery and payment (i) trading in the Partnership’s Partnership Units shall have been suspended by the Commission or the Nasdaq, (ii) trading in securities generally on the New York Stock Exchange or the Nasdaq 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 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 Representatives, impractical or inadvisable to proceed with the offering or delivery of the Units as contemplated by the Preliminary Prospectus or the Prospectus.
          11. Representations and Indemnities to Survive. The respective agreements, representations, warranties, indemnities and other statements of the Targa Parties or their respective officers and of the Underwriters 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 any Underwriter or the Targa Parties or any of the officers, directors, employees, agents or controlling persons referred to in Section 8 hereof, and will survive delivery of and payment for the Units. The provisions of Sections 7 and 8 hereof shall survive the termination or cancellation of this Agreement.
          12. Notices.

General Counsel (fax no.: (212)  ###-###-####) and confirmed to the General Counsel, Citigroup Global Markets Inc., at 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 400, Houston, Texas 77002, attention of Paul W.

          13. 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 8 hereof, and no other person will have any right or obligation hereunder.
          14. No Fiduciary Duty. Each of the Targa Parties hereby acknowledges that (a) the purchase and sale of the Units pursuant to this Agreement is an arm’s-length commercial transaction between the Targa Parties, on the one hand, and the Underwriters and any affiliate through which it may be acting, on the other, (b) the Underwriters are acting as principal and not as an agent or fiduciary of the Targa Parties and (c) the Targa Parties’ engagement of the Underwriters in connection with the offering and the process leading up to the offering is as independent contractors and not in any other capacity. Furthermore, each of the Targa Parties agrees that it is solely responsible for making its own judgments in connection with the offering (irrespective of whether any of the Underwriters has advised or is currently advising the Targa

46


 

Parties on related or other matters). Each of the Targa Parties agrees that it will not claim that the Underwriters have rendered advisory services of any nature or respect, or owe an agency, fiduciary or similar duty to any of the Targa Parties, in connection with such transaction or the process leading thereto.
          15. Integration. This Agreement supersedes all prior agreements and understandings (whether written or oral) between the Targa Parties and the Underwriters, or any of them, with respect to the subject matter hereof.
          16. Applicable Law. This Agreement will be governed by and construed in accordance with the laws of the State of New York applicable to contracts made and to be performed within the State of New York.
