(aa)             Each of the Company, the Partnership and KMI maintains disclosure controls and procedures (as such term is defined in Rule 13a-15(e) under the Exchange Act) that comply with the requirements of the Exchange Act; such disclosure controls and procedures have been designed to ensure that material information relating to each such entity and its consolidated subsidiaries is made known to the principal executive officer and principal financial officer of such entity by others within those entities; and each such entity believes that its disclosure controls and procedures are effective in all material respects to provide reasonable assurance that information required to be disclosed in the reports it files under the Exchange Act is recorded, processed, summarized and reported as and when required; and

(bb)             None of the Company, the Partnership or KMI has distributed or, prior to the later to occur of the Closing Date and completion of the distribution of the Purchased Securities, will distribute any offering material in connection with the offering and sale of the Purchased Securities other than any Preliminary Prospectus, the Prospectus and any Issuer Free Writing Prospectus to which the Underwriters have consented to the use thereof.

(d)           Subsequent to the execution of this Agreement, there shall not have occurred any of the following: (i) a suspension or material limitation in trading in securities generally on the New York Stock Exchange; (ii) a suspension in trading in the Company’s, the Partnership’s or KMI’s securities on the New York Stock Exchange; (iii) a general moratorium on commercial banking activities declared by either Federal or New York or Texas State authorities or a material disruption in commercial banking or securities settlement or clearance services in the United States; (iv) the outbreak or escalation of major hostilities involving the United States or the declaration by the United States of a national emergency or war; or (v) the occurrence of any other calamity or crisis or any change in financial, political or economic conditions in the United States or elsewhere, if the effect of any such event specified in clause (iv) or (v) in the judgment of the Underwriters makes it impracticable or inadvisable to proceed with the public offering or the sale of and payment for the Purchased Securities on the terms and in the manner contemplated in the Prospectus.

(e)           The Company has obtained and delivered to the Underwriters executed copies of lock-up agreements to the Underwriters from (i) the executive officers and directors of the Company, in the form set forth as Annex B-1 hereto and (ii) the General Partner, in the form set forth as Annex B-2 hereto.

(j)            Subsequent to the date of this Agreement, no downgrading shall have occurred in the rating accorded the Partnership’s debt securities or preferred stock by any “nationally recognized statistical rating organization,” as that term is defined in Section 3(a)(62) of the Exchange Act, nor shall there have been any public announcement, beyond what it had announced prior to the date of this Agreement, that any such organization has under surveillance or review its ratings of any debt securities or preferred stock of the Partnership (other than an announcement with positive implication of a possible upgrading, and no implication of a possible downgrading of such rating).

6.             Covenants.  Each of the Company, the Partnership and KMI covenants and agrees with the several Underwriters as follows:

(a)           To advise the Underwriters promptly of any amendment or supplement of the Registration Statement or the Prospectus which is proposed to be filed and not to effect such amendment or supplement in a form to which the Underwriters reasonably object.

(b)           To furnish to each of the Underwriters and to the counsel for the Underwriters, one copy of the Registration Statement filed pursuant to EDGAR, including exhibits and Incorporated Documents, relating to the Shares in the form it became effective and of all amendments thereto, including exhibits; and to each such firm and counsel, copies of each Preliminary Prospectus and Prospectus and any amendment or supplement thereto relating to the Purchased Securities.

(c)           As soon as it is advised thereof, to advise the Underwriters of (i) the initiation or threatening by the Commission of any proceedings for the issuance of any order suspending the effectiveness of the Registration Statement or suspending the use of the Prospectus, (ii) receipt by it or any representative or attorney of it of any other communication from the Commission relating to the Company, the Partnership, KMI, the Registration Statement, the Preliminary Prospectus, the Prospectus or any Issuer Free Writing Prospectus, or (iii) suspension of qualification of the Purchased Securities for offering or sale in any jurisdiction or the institution or threatening of any proceeding for such purpose.  The Company, the Partnership and KMI will make every reasonable effort to prevent the issuance of an order suspending the effectiveness of the Registration Statement or the use of the Prospectus, any Preliminary Prospectus or any Issuer Free Writing Prospectus, and if any such order is issued, to obtain as soon as possible the lifting thereof.

(d)           To deliver to the Underwriters, without charge, as many conformed copies of the Registration Statement (excluding exhibits but including the Incorporated Documents), the Preliminary Prospectus, the Prospectus and each Issuer General Use Free Writing Prospectus and all amendments and supplements to such documents as the Underwriters may reasonably request.

(e)           During such period as a Prospectus is required by law to be delivered by an Underwriter or dealer, to deliver, without charge, to Underwriters and dealers, at such office or offices as the Underwriters may designate, as many copies of the Prospectus and any amendment or supplement thereto as the Underwriters may reasonably request.

(f)            During the period in which copies of the Prospectus are to be delivered as provided in paragraph (e) above, if any event occurs as a result of which the Prospectus as then amended or supplemented would include an untrue statement of a material fact or omit to state any material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading, or if for any reason it shall be necessary during such same period to amend the Registration Statement or amend or supplement the Prospectus to comply with the Securities Act or file any document which will be deemed an Incorporated Document in order to comply with the Exchange Act and the rules and regulations thereunder, forthwith to prepare, submit to the Underwriters, file with the Commission and deliver, without charge to the Underwriters either (i) amendments or supplements to the Registration Statement or Prospectus so that the statements in the Registration Statement or Prospectus, as so amended or supplemented, will not be misleading or (ii) such amendments, supplements or documents which will effect such compliance.  Delivery by the Underwriters of any such amendments or supplements to the Prospectus or documents shall not constitute a waiver of any of the conditions set forth in Section 5 hereof.

(g)           To retain in accordance with the Rules all Issuer Free Writing Prospectuses not required to be filed pursuant to the Rules; and if at any time after the date of the Underwriting Agreement any events shall have occurred as a result of which any Issuer Free Writing Prospectus, as then amended or supplemented, would conflict with the information in the Registration Statement, the Preliminary Prospectus or the Prospectus or would include an untrue statement of a material fact or omit to state any material fact necessary in order to make the statements therein, in the light of the circumstances prevailing at that subsequent time, not misleading, to notify the Underwriters and promptly amend or supplement, at their own expense, such Issuer Free Writing Prospectus to eliminate or correct such conflict, untrue statement or omission.

(h)           To make generally available to the Company’s shareholders, as soon as practicable, an earnings statement which satisfies the provisions of Section 11(a) of the Securities Act.

(i)            To cooperate with the Underwriters in qualifying the Purchased Securities for offer and sale under the securities or “blue sky” laws of such jurisdictions as the Underwriters may reasonably request; provided that in no event shall the Company, the Partnership nor KMI be obligated to qualify to do business in any

jurisdiction where it is not now so qualified, to take any action which would subject it to service of process in suits, other than those arising out of the offering or sale of the Purchased Securities, in any jurisdiction where it is not now so subject, to qualify in any jurisdiction as a broker-dealer or to subject itself to any taxing authority where it is not now so subject.

(j)            Unless otherwise specified, to effect the listing of the Purchased Securities on the New York Stock Exchange prior to the Closing Date, subject to notice of issuance.

(k)           During the period of five years from the date hereof, to supply to the Underwriters, if requested in writing, copies of such financial statements and other periodic and special reports as the Company may from time to time distribute generally to its lenders or to the holders of any class of its securities registered under Section 12 of the Exchange Act and to furnish to the Underwriters a copy of each annual or other report it shall be required to file with the Commission.

(l)            To pay all of its own expenses incurred in connection with the performance of its obligations under this Agreement, and the Company will pay or cause to be paid, or reimburse or cause to be reimbursed if paid by the Underwriters, whether or not the transactions contemplated hereby are consummated or this Agreement is terminated, all reasonable costs and expenses incident to the performance of the obligations of the Company, the Partnership and KMI under this Agreement, including those relating to (i) the preparation, printing and filing of the Registration Statement and exhibits thereto, each Preliminary Prospectus, the Prospectus, any Issuer Free Writing Prospectus and any amendments or supplements thereto, and the printing of this Agreement, (ii) the issuance, preparation and delivery of the Purchased Securities to the Underwriters, and the issuance, preparation and delivery of the i-units to the Company, in each such case, including the costs and expenses of any registrar, transfer agent and any agent thereof, including any reasonable fees and disbursements of counsel therefor, (iii) the registration or qualification of the Purchased Securities for offer and sale under the securities or “blue sky” laws of the various jurisdictions referred to in paragraph (i) above, including the reasonable fees and disbursements of counsel for the Underwriters in connection therewith and the preparation and printing of legal investment and preliminary and supplementary “blue sky” memoranda, (iv) the furnishing to the Underwriters of copies of the Preliminary Prospectus, the Prospectus, any Issuer Free Writing Prospectus and any amendments or supplements thereto, and of the several documents required by this Section to be so furnished, including costs of shipping and mailing, (v) the listing of the Purchased Securities on any securities exchange, and (vi) the furnishing to the Underwriters of copies of all reports and information required by Section 6(k) above, including costs of shipping and mailing.  If a separate agreement exists among the Company, the Partnership and KMI which allocates such costs and expenses in a manner different from that set forth above, such agreement shall control as among the Company, the Partnership and KMI, but such agreement shall not modify the obligations of the Company to the Underwriters to cause the payment of costs and expenses as set forth above.

(m)          During the period beginning on the date of this Agreement and continuing to and including the date 45 days after the date of this Agreement, not to, directly or indirectly, without the prior written consent of the Barclays Capital Inc. (1) offer for sale, sell, contract to sell, pledge, hedge, grant an option to purchase, issue or otherwise dispose of (or enter into any transaction or device that is designed to, or could be expected to, result in the disposition by any person at any time in the future of) any Shares, common units representing limited partner interests (“Common Units”) in the Partnership, or Class B units of the Partnership (the “Class B Units”) or any other securities substantially similar to, convertible into or exchangeable or exercisable for, or representing the right to receive, Shares, Common Units or Class B Units or (2) enter into any swap or other derivatives transaction that transfers to another, in whole or in part, any of the economic benefits or risks of ownership of such Shares, Common Units or Class B Units or any securities substantially similar to, convertible into or exchangeable or exercisable for, or representing the right to receive Shares, Common Units or Class B Units, whether any such transaction described in clause (1) or (2) above is to be settled by delivery of the Shares or other securities, in cash or otherwise; provided however, that the above restrictions shall not apply to (i) the sale of Shares to the Underwriters pursuant to the Underwriting Agreement, (ii) transactions for the acquisition of assets, businesses or the capital stock or other ownership interests of businesses in exchange for Shares, Common Units or Class B Units or any securities substantially similar to, convertible into or exchangeable or exercisable for Shares, Common Units or Class B Units, (iii) the sale of i-units by the Partnership to the Company, (iv) the issuance of Shares, Common Units or Class B Units pursuant to any existing employee benefit plans, option plans or compensation plans or (v) the issuance of Shares or i-units as distributions on then outstanding Shares or i-units, respectively.

(n)          The Partnership agrees to have duly and validly authorized and issued, and the Company agrees to purchase from the Partnership on the Closing Date, a number of i-units equal to the number of Purchased Securities sold on the Closing Date.

7.             Indemnification.

(a)           Each of the Company, the Partnership and, with respect to information regarding itself, KMI, will indemnify and hold harmless each Underwriter and each person, if any, who controls any Underwriter within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act, and each entity that is an “affiliate” (as defined in Rule 405 of the Rules) of any Underwriter and that has participated in the distribution of the Purchased Securities as an underwriter, as follows:

(i)            against any and all loss, liability, claim, damage and expense whatsoever, to which such Underwriter may become subject, arising out of or based upon any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement (or any amendment thereto), or the omission or alleged omission therefrom of a material fact required to be stated therein or necessary to make the statements therein not misleading or arising out of any untrue statement or alleged untrue statement of a material fact contained in any Preliminary Prospectus, the Prospectus or any Issuer Free Writing Prospectus

(or any amendment or supplement to such documents), or the omission or alleged omission therefrom of a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading;

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

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

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

(b)           Each Underwriter, severally in proportion to its respective purchase obligation and not jointly, agrees to indemnify and hold harmless KMI, the Partnership, the General Partner, the Company, the directors of the General Partner and the Company, the directors of KMI, the officers of the Company and KMI who signed the Registration Statement, and each person, if any, who controls KMI, the Partnership, the General Partner or the Company within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act, against any and all loss, liability, claim, damage and expense described in the indemnity contained in Section 7(a) above, as incurred, but only with respect to untrue statements or omissions, or alleged untrue statements or omissions, made in the Registration Statement, any Preliminary Prospectus or the Prospectus (or any amendment or supplement to such documents), or any Issuer Free Writing Prospectus, in reliance upon and in conformity with written information furnished to the Company, the Partnership or KMI by or on behalf of such Underwriter expressly for use in the Registration Statement, any Preliminary Prospectus or the Prospectus (or any amendment or supplement to such documents), or any Issuer Free Writing Prospectus, it being understood and agreed that the only such information consists of the following: (i) the information in the fourth paragraph under the caption “Underwriting” in the Preliminary

Prospectus and Prospectus concerning the terms of the offering of the Shares by the Underwriters; (ii) the information in the twelfth and thirteenth paragraphs under the caption “Underwriting” in the Preliminary Prospectus and the Prospectus concerning stabilization, over-allotment, syndicate transactions and penalty bids; and (iii) the information in the fifteenth paragraph under the caption “Underwriting” in the Preliminary Prospectus and the Prospectus concerning the availability of the Prospectus in electronic format on websites maintained by the Underwriters.

(c)           Each indemnified party shall give written notice as promptly as reasonably practicable to each indemnifying party of any action commenced against it in respect of which indemnity may be sought hereunder, but failure to so notify an indemnifying party shall not relieve such indemnifying party from any liability hereunder to the extent it is not materially prejudiced as a result thereof and in any event shall not relieve it from any liability which it may have otherwise than on account of this indemnity agreement.  In the case of parties indemnified pursuant to Section 7(a) above, counsel to the indemnified parties shall be selected by the Underwriters, and, in the case of parties indemnified pursuant to Section 7(b) above, counsel to the indemnified parties shall be selected by the Company, provided that if it so elects within a reasonable time after receipt of such notice, an indemnifying party, jointly with any other indemnifying parties receiving such notice, may assume the defense of such action with counsel chosen by it and approved by the indemnified parties defendant in such action, unless such indemnified parties reasonably object to such assumption on the ground that there may be legal defenses available to them which are different from or in addition to those available to such indemnifying party.  If an indemnifying party assumes the defense of such action, the indemnifying parties shall not be liable for any fees and expenses of counsel for the indemnified parties incurred thereafter in connection with such action; provided, however, that the indemnifying party shall pay the fees and expenses of separate counsel for the indemnified party if (i) the indemnifying party has agreed to pay such fees and expenses or (ii) counsel for the indemnified party reasonably determines that representation of both the indemnifying party and the indemnified party by the same counsel would create a conflict of interest.  An indemnifying party may participate at its own expense in the defense of any such action; provided, however, that counsel to the indemnifying party shall not (except with the consent of the indemnified party) also be counsel to the indemnified party.  In no event shall the indemnifying parties be liable for fees and expenses of more than one counsel (in addition to any local counsel) separate from their own counsel for all indemnified parties in connection with any one action or separate but similar or related actions arising out of the same general allegations or circumstances.  No indemnifying party shall, without the prior written consent of the indemnified parties, settle or compromise or consent to the entry of any judgment with respect to any litigation, or any investigation or proceeding by any governmental agency or body, commenced or threatened, or any claim whatsoever in respect of which indemnification or contribution could be sought under this Section 7 or Section 8 hereof (whether or not the indemnified parties are actual or potential parties thereto), unless such settlement, compromise or consent (i) includes an unconditional release of each indemnified party from all liability arising out of such litigation, investigation, proceeding or claim and (ii) does not include a statement as to or an admission of fault, culpability or a failure to act by or on behalf of any indemnified party.

(d)           If at any time an indemnified party shall have requested an indemnifying party to reimburse the indemnified party for reasonable fees and expenses of counsel, such indemnifying party agrees that it shall be liable for any settlement of the nature contemplated by Section 7(a)(ii) effected without its written consent if (i) such settlement is entered into more than 45 days after receipt by such indemnifying party of the aforesaid request, (ii) such indemnifying party shall have received notice of the terms of such settlement at least 30 days prior to such settlement being entered into and (iii) such indemnifying party shall not have reimbursed such indemnified party in accordance with such request prior to the date of such settlement.  Notwithstanding the immediately preceding sentence, if at any time an indemnified party shall have requested an indemnifying party to reimburse the indemnified party for fees and expenses of counsel, an indemnifying party shall not be liable for any settlement of the nature contemplated by Section 7(a)(ii) effected without its consent if such indemnifying party (i) reimburses such indemnified party in accordance with such request to the extent it considers such request to be reasonable and (ii) provides written notice to the indemnified party substantiating the unpaid balance as unreasonable, in each case prior to the date of such settlement.

8.             Contribution.  If the indemnification provided for in Section 7 hereof is for any reason unavailable to or insufficient to hold harmless an indemnified party in respect of any losses, liabilities, claims, damages or expenses referred to therein, then each indemnifying party shall contribute to the aggregate amount of such losses, liabilities, claims, damages and expenses incurred by such indemnified party, as incurred, (i) in such proportion as is appropriate to reflect the relative benefits received by the Company, the Partnership and KMI on the one hand and the Underwriters on the other hand from the offering of the Purchased Securities pursuant to this Agreement or (ii) if the allocation provided by clause (i) is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to in clause (i) above but also the relative fault of the Company, the Partnership and KMI on the one hand and of the Underwriters on the other hand in connection with the statements or omissions which resulted in such losses, liabilities, claims, damages or expenses, as well as any other relevant equitable considerations.  The relative benefits received by the Company, the Partnership and KMI on the one hand and the Underwriters on the other hand in connection with the offering of the Purchased Securities pursuant to this Agreement shall be deemed to be in the same respective proportions as the total net proceeds from the offering of the Purchased Securities pursuant to this Agreement (before deducting expenses but after deducting the total underwriting commission received by the Underwriters) received by the Company and the total underwriting commission received by the Underwriters, in each case as set forth on the cover of the Prospectus, bear to the aggregate initial public offering price of the Purchased Securities as set forth on such cover.  The relative fault of the Company, the Partnership and KMI on the one hand and the Underwriters on the other hand shall be determined by reference to, among other things, whether any such untrue or alleged untrue statement of a material fact or omission or alleged omission to state a material fact relates to information supplied by the Company, the Partnership and KMI or by the Underwriters and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission.  The Company, the Partnership, KMI and the Underwriters agree that it would not be just and equitable if contribution pursuant to this Section 8 were determined by pro rata allocation (even if the Underwriters were treated as one entity for such purpose) or by any other method of allocation

which does not take account of the equitable considerations referred to above in this Section 8.  The aggregate amount of losses, liabilities, claims, damages and expenses incurred by an indemnified party and referred to above in this Section 8 shall be deemed to include any legal or other expenses reasonably incurred by such indemnified party in investigating, preparing or defending against any litigation, or any investigation or proceeding by any governmental agency or body, commenced or threatened, or any claim whatsoever based upon any such untrue or alleged untrue statement or omission or alleged omission.  Notwithstanding the provisions of this Section 8, no Underwriter shall be required to contribute any amount in excess of the amount by which the total price at which the Purchased Securities underwritten by it and distributed to the public were offered to the public exceeds the amount of any damages which such Underwriter has otherwise been required to pay by reason of any such untrue or alleged untrue statement or omission or alleged omission.  No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities 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, if any, who controls an Underwriter within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act shall have the same rights to contribution as such Underwriter; each director of KMI, the General Partner and the Company, each officer of KMI and the Company who signed the Registration Statement, and each person, if any, who controls KMI, the Partnership, the General Partner or the Company within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act shall have the same rights to contribution as KMI, the Partnership, the General Partner and the Company.  The various Underwriters’ respective obligations to contribute pursuant to this Section 8 are several in proportion to their respective underwriting obligations and not joint.

The respective obligations of the Company, the Partnership and KMI under this Section 8 shall be in addition to any liability which the Company, the Partnership or KMI may otherwise have.

9.             Termination.  This Agreement may be terminated by the Underwriters by notifying the Company at any time at or prior to the Closing Date, if any of the conditions specified in Section 5 hereof shall not have been fulfilled when and as required by this Agreement.

If this Agreement is terminated pursuant to any of the provisions hereof, except as otherwise provided herein, neither the Company, the Partnership, nor KMI shall be under any liability to any Underwriter and no Underwriter shall be under any liability to the Company, the Partnership or KMI, except that (a) if this Agreement is terminated by the Underwriters because of any failure or refusal on the part of the Company, the Partnership or KMI to comply with the terms of this Agreement or because any of the conditions contained in Section 5 of this Agreement, other than Section 5(j) or Sections 5(d)(i), (iii), (iv) or (v), have not been met, the Company shall reimburse or cause to be reimbursed the Underwriters for all reasonable out-of-pocket expenses (including the reasonable fees and disbursement of their counsel) reasonably incurred by them and (b) no Underwriter who shall have failed or refused to purchase the Purchased Securities agreed to be purchased by it hereunder, without some reason sufficient hereunder to justify its cancellation or termination of its obligations hereunder, shall be relieved of liability to the Company, the Partnership and KMI for damages occasioned by its default.

10.         Default of Underwriters.  If one or more of the Underwriters shall fail (other than for a reason sufficient to justify the termination of this Agreement) to purchase on the Closing Date the number of Purchased Securities agreed to be purchased by such Underwriter or Underwriters, the remaining Underwriter or Underwriters may find one or more substitute underwriters to purchase such Purchased Securities or make such other arrangements as they may deem advisable or one or more of the remaining Underwriters may agree to purchase such Purchased Securities in such proportions as may be approved by the remaining Underwriter or Underwriters, in each case upon the terms herein set forth.  If no such arrangements have been made within 24 hours after the Closing Date, and

(a)           the aggregate number of Purchased Securities to be purchased by the defaulting Underwriter or Underwriters shall not exceed 10% of the total number of Purchased Securities, each of the non-defaulting Underwriters shall be obligated to purchase such Purchased Securities on the terms herein set forth in proportion to their respective obligations hereunder, or

(b)           the aggregate number of Purchased Securities to be purchased by the defaulting Underwriter or Underwriters shall exceed 10% of the total number of Purchased Securities, the Company shall be entitled to an additional period of 24 hours within which to find one or more substitute underwriters satisfactory to the remaining Underwriter or Underwriters to purchase such Purchased Securities, upon the terms set forth herein.
