Ladies and Gentlemen:

Camden Property Trust, a Texas real estate investment trust (the “Company”), proposes to issue and sell to Banc of America Securities LLC (“BAS”) and J.P. Morgan Securities Inc. (“JPM”) and each of the other Underwriters named in Schedule I hereto (collectively, the “Underwriters”, which term shall also include any Underwriter substituted as hereinafter provided in Section 10 hereof), for whom BAS and JPM are acting as representatives (in such capacity, the “Representatives”), with respect to the issue and sale by the Company and the purchase by the Underwriters, acting severally and not jointly, of the respective principal amounts of $300,000,000 aggregate principal amount of the Company’s 5.700% Notes due 2017 (the “Notes”) set forth in said Schedule I. The Notes are to be issued pursuant to a senior indenture dated as of February 11, 2003 (the “Base Indenture”) between the Company and U.S. Bank National Association as successor to SunTrust Bank, as trustee (the “Trustee”), as supplemented by a supplemental indenture to be dated as of the Closing Date (as defined in Section 3(a) hereof) between the Company and the Trustee (the “Supplemental Indenture”, and together with the Base Indenture, the “Indenture”).

Notes issued in book-entry form will be issued to Cede & Co. as nominee of The Depository Trust Company (“DTC”) pursuant to a blanket letter of representations dated as of December 4, 2003 between the Company and DTC.

The Company has filed with the Securities and Exchange Commission (the “Commission”) an automatic shelf registration statement on Form S-3 (No. 333-135195), including the related base prospectus, which registration statement became effective upon filing under Rule 462(e) of the rules and regulations of the Commission (the “Securities Act Regulations”) under the Securities Act of 1933, as amended (the “Securities Act”). Such registration statement covers the registration of the Notes under the Securities Act. Promptly after execution and delivery of this Agreement, the Company will prepare and file a prospectus supplement relating to the Notes in accordance with the provisions of Rule 430B (“Rule 430B”) of the Securities Act Regulations and paragraph (b) of Rule 424 (“Rule 424(b)”) of the Securities Act Regulations. Any information included in such prospectus supplement that was omitted from such registration statement at the time it became effective but that is deemed to be part of and included in such registration statement pursuant to Rule 430B is referred to as “Rule 430B Information.” Each prospectus used in connection with the offering of the Notes that omitted Rule 430B Information, together with the documents incorporated by reference therein pursuant to Item 12 of Form S-3 under the Securities Act, is herein called a “preliminary prospectus.” Such registration statement, at any given time, including the amendments thereto at such time, the exhibits and any schedules thereto at such time, the documents incorporated by reference therein pursuant to Item 12 of Form S-3 under the Securities Act at such time and the documents otherwise deemed to be a part thereof or included therein by the Securities Act Regulations, is herein called the “Registration Statement;” provided, however, that the term “Registration Statement” shall be deemed to include information contained in the final prospectus supplement relating to the Notes that is retroactively deemed to be a part of such registration statement (as amended) as of the time specified in Rule 430B of the Securities Act Regulations. The Registration Statement at the time it originally became effective is herein called the “Original Registration Statement.” The base prospectus and the final prospectus supplement in the form first furnished to the Underwriters for use in connection with the offering of the Notes, including the documents incorporated by reference therein pursuant to Item 12 of Form S-3 under the Securities Act at the time of the execution of this Agreement is hereinafter referred to as the “Prospectus.” For purposes of this Agreement, all references to the Registration Statement, any preliminary prospectus, the Prospectus or any amendment or supplement to any of the foregoing shall be deemed to include the copy filed with the Commission pursuant to its Electronic Data Gathering, Analysis and Retrieval system (“EDGAR”).

All references in this Agreement to financial statements and schedules and other information which is “contained,” “included” or “stated” in the Registration Statement, any preliminary prospectus or the Prospectus (or other references of like import) shall be deemed to mean and include all such financial statements and schedules and other information which is incorporated by reference in or otherwise deemed by the Securities Act Regulations to be a part of or included in the Registration Statement, any preliminary prospectus or the Prospectus, as the case may be; and all references in this Agreement to amendments or supplements to the Registration Statement, any preliminary prospectus or the Prospectus shall be deemed to mean and include the filing of any document under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), which is incorporated by reference in or otherwise deemed by the Securities Act Regulations to be a part of or included in the Registration Statement, such preliminary prospectus or the Prospectus, as the case may be, after the most recent effective date prior to the execution of this Agreement, in the case of the Registration Statement, or the

respective dates of the Prospectus or any preliminary prospectus, in the case of the Prospectus and any preliminary prospectus.

The Company hereby agrees with each Underwriter as follows:

1. On the basis of the representations and warranties herein contained and subject to the terms and conditions herein set forth, the Company agrees to sell to each Underwriter, severally and not jointly, and each Underwriter, severally and not jointly, agrees to purchase from the Company, at the price set forth in Section 3(a) hereof, the aggregate principal amount of Notes set forth in Schedule I opposite the name of such Underwriter, plus any additional principal amount of Notes which such Underwriter may become obligated to purchase pursuant to the provisions of Section 10 hereof.

2. The Company understands that the Underwriters intend to make a public offering of the Notes and initially to offer the Notes upon the terms set forth in this Agreement as soon as the Representatives deem advisable after this Agreement has been executed and delivered.

3. On the Closing Date:

(a) Payment of the purchase price for, and delivery of, the Notes shall be made at the offices of Sidley Austin LLP, New York, New York, or at such other place as shall be agreed upon by the Representatives and the Company at 9:00 A.M. (Eastern time) on the third (fourth, if the pricing occurs after 4:30 P.M. (Eastern time) on any given day) business day following the date of this Agreement, or such other time not later than ten business days after such date as shall be agreed upon by the Representatives and the Company (such time and date of payment and delivery being herein called the “Closing Date”). Payment shall be made to the Company by wire transfer of immediately available funds to a bank account designated by the Company, against delivery to the Representatives of one or more global certificates for the Notes to be purchased by the Underwriters. The Company will deliver against payment of the purchase price (99.00% of the aggregate principal amount of the Notes, plus accrued interest from May 4, 2007) the Notes in the form of a permanent global security in definitive form (the “Global Security”) deposited with the Trustee as custodian for DTC and registered in the name of Cede & Co., as nominee for DTC. Interests in the Global Security will be held only in book-entry form through DTC, except in the limited circumstances described in the Prospectus.

(b) The Representatives, individually and not as representatives of the several Underwriters may (but shall not be obligated to) make payment of the purchase price for the Notes to be purchased by any Underwriter whose funds have not been received by the Closing Date, but any such payment shall not relieve such Underwriter from its obligations hereunder.

(c) The Notes shall be issued in such authorized denominations and registered in such names as the Representatives may request in writing at least one full business day before the Closing Date. The Notes will be made available for examination and

packaging by the Representatives not later than 10:00 A.M. (Eastern time) on the business day prior to the Closing Date.

4. The Company represents and warrants to each Underwriter as of the date hereof and as of the Closing Date that:

(a) (I) At the time of filing the Original Registration Statement, (II) at the time of the most recent amendment thereto, if any, for the purposes of complying with Section 10(a)(3) of the Securities Act (whether such amendment was by post-effective amendment, incorporated report filed pursuant to Section 13 or 15(d) of the Exchange Act or form of prospectus), (III) at the time the Company or any person acting on its behalf (within the meaning, for this clause only, of Rule 163(c) of the Securities Act Regulations) made any offer relating to the Notes in reliance on the exemption of Rule 163 of the Securities Act Regulations (“Rule 163”) and (IV) at the date hereof, the Company was and is a “well-known seasoned issuer” as defined in Rule 405 of the Securities Act Regulations (“Rule 405”). The Registration Statement is an “automatic shelf registration statement,” as defined in Rule 405. The Company is and remains eligible to use an automatic shelf registration statement and the Notes, since their registration on the Registration Statement, have been and remain eligible for registration by the Company on a Rule 405 “automatic shelf registration statement”. The Company has not received from the Commission any notice pursuant to Rule 401(g)(2) of the Securities Act Regulations (“Rule 401(g)(2)”) objecting to the use of the automatic shelf registration statement form.

At the time of filing the Original Registration Statement, at the earliest time thereafter that the Company or another offering participant made a bona fide offer (within the meaning of Rule 164(h)(2) of the Securities Act Regulations) of the Notes and at the date hereof, the Company was not and is not an “ineligible issuer,” as defined in Rule 405.

The Original Registration Statement became effective upon filing under Rule 462(e) of the Securities Act Regulations (“Rule 462(e)”) on June 21, 2006, and any post-effective amendment thereto also became effective upon filing under Rule 462(e). No stop order suspending the effectiveness of the Registration Statement has been issued under the Securities Act and no proceedings for that purpose have been instituted or are pending or, to the knowledge of the Company, are contemplated by the Commission, and any request on the part of the Commission for additional information has been complied with.

Any offer that is a written communication relating to the Notes made prior to the filing of the Original Registration Statement by the Company or any person acting on its behalf (within the meaning, for this paragraph only, of Rule 163(c) of the Securities Act Regulations) has been filed with the Commission in accordance with the exemption provided by Rule 163 and otherwise complied with the requirements of Rule 163, including without limitation the legending requirement, to qualify such offer for the exemption from Section 5(c) of the Securities Act provided by Rule 163.

At the respective times the Original Registration Statement and any post-effective amendments thereto became effective, at each deemed effective date with respect to the Underwriters pursuant to Rule 430B(f)(2) of the Securities Act Regulations, at the date of this Agreement and at the Closing Date, the Registration Statement, complied and will comply in all material respects with the requirements of the Securities Act and the Securities Act Regulations, and did not and will not contain an untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein not misleading.

The Prospectus and any amendments or supplements thereto, at the time the Prospectus or any such amendment or supplement was issued and at the Closing Date, complied, complies and will comply in all material respects with the requirements of the Securities Act and the Securities Act Regulations, and did not, does not and will not include an untrue statement of a material fact or omit to state a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading.

Any preliminary prospectus (including the base prospectus filed as part of the Original Registration Statement or any amendment thereto) complied when so filed in all material respects with the Securities Act and the Securities Act Regulations and any such preliminary prospectus and the Prospectus delivered to the Underwriters for use in connection with this offering was identical to the electronically transmitted copies thereof filed with the Commission pursuant to EDGAR, except to the extent permitted by Regulation S-T.

As of the Applicable Time, any Issuer Free Writing Prospectus (as defined below) identified on Schedule II issued at or prior to the Applicable Time and the Statutory Prospectus (as defined below), all considered together (collectively, the “General Disclosure Package”), did not include any 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.

The representations and warranties in the preceding four paragraphs shall not apply to statements in or omissions from the Registration Statement or any post-effective amendment thereto, or the Prospectus, or any amendments or supplements thereto, or the General Disclosure Package, made in reliance upon and in conformity with information furnished to the Company in writing by any Underwriter through the Representatives expressly for use in the Registration Statement or any post-effective amendment thereto, or the Prospectus, or any amendments or supplements thereto, or the General Disclosure Package.

Any certificate signed by any officer of the Company and delivered to the Representatives or to counsel for the Underwriters in connection with the offering of the Notes shall be deemed a representation and warranty by the Company to each Underwriter as to the matters covered thereby on the date of such certificate.

5. The Company covenants and agrees with each Underwriter as follows:

(a) Immediately following the execution of this Agreement, the Company will prepare a Prospectus setting forth the aggregate principal amount of Notes covered thereby and their terms not otherwise specified in the preliminary prospectus, the names of the Underwriters, the price at which the Notes are to be purchased by the Underwriters from the Company, and such other information as the Representatives and the Company deem appropriate in connection with the offering of the Notes; and the Company will effect the filings required under Rule 424(b), in the manner and within the time period required by Rule 424(b) (without reliance on Rule 424(b)(8)), and will furnish to the Underwriters as many copies (including by electronic means, if so requested in lieu of paper copies) of the Prospectus as they shall reasonably request, including, if requested

by the Underwriters, in addition to or in lieu thereof, electronic copies of the Prospectus. The Company shall pay the required Commission filing fees relating to the Notes within the time required by Rule 456(b)(1)(i) of the Securities Act Regulations and otherwise in accordance with Rules 456(b) and 457(r) of the Securities Act Regulations.

(b) The Company will comply with the requirements of Rule 430B and will notify the Representatives immediately, and confirm the notice in writing, (a) of the effectiveness of any amendment to the Registration Statement, (b) of the transmittal to the Commission for filing of any supplement or amendment to the Prospectus or any document to be filed pursuant to the Exchange Act, (c) of the receipt of any comments from the Commission with respect to the Registration Statement, the General Disclosure Package or the Prospectus or documents incorporated or deemed to be incorporated by reference therein, (d) of any request by the Commission for any amendment to the Registration Statement or any amendment or supplement to the General Disclosure Package or the Prospectus with respect to the Notes or for additional information relating thereto, and (e) of the issuance by the Commission of any stop order suspending the effectiveness of the Registration Statement or the initiation of any proceedings for that purpose. The Company will make every reasonable effort to prevent the issuance of any such stop order and, if any stop order is issued, to obtain the lifting thereof at the earliest possible moment.

(c) During the period beginning on the Applicable Time and ending on the later of the Closing Date or such date, as in the reasonable opinion of counsel for the Underwriters, the Prospectus is no longer required under the Securities Act or the Exchange Act to be delivered in connection with sales by the Underwriters or a dealer, including in circumstances where such requirement may be satisfied pursuant to Rule 172 (the “Prospectus Delivery Period”), prior to amending or supplementing the Registration Statement (including any filing under Rule 462(b)), any preliminary prospectus or the Prospectus (including any amendment or supplement through incorporation by reference of any report filed under the Exchange Act), the Company will furnish to the Representatives for review a copy of each such proposed amendment or supplement a reasonable amount of time prior to such proposed filing or use, as the case may be, and will not file any such amendment or supplement or use any such prospectus to which counsel for the Underwriters shall reasonably object. The Company has given the Representatives notice of any filings made pursuant to the Exchange Act or Exchange Act Regulations within 48 hours prior to the Applicable Time; the Company will give the Representatives notice of its intention to make any such filing from the Applicable Time to the Closing Date and will furnish the Representatives with copies of any such documents a reasonable amount of time prior to such proposed filing and will not file or use any such document to which the Representatives or counsel for the Underwriters shall reasonably object. The Company will prepare a final term sheet substantially in the form set forth as Annex A to Schedule II hereto (the “Final Term Sheet”) reflecting the final terms of the Notes, and shall promptly file such Final Term Sheet as an “issuer free writing prospectus” pursuant to Rule 433 as soon as possible after the execution of this Agreement; provided that the Company shall furnish the Representatives with copies of the any such Final Term Sheet a reasonable amount of time prior to such proposed filing

and will not use or file any such document to which the Representatives or counsel to the Underwriters shall reasonable object.

(d) The Company will deliver to the Representatives a conformed copy of the Original Registration Statement as originally filed and of each amendment thereto filed prior to the termination of the initial offering of the Notes (including exhibits filed therewith or incorporated by reference therein and the documents incorporated by reference into the Prospectus pursuant to Item 12 of Form S-3).

(e) The Company will furnish to the Representatives, from time to time during the period when the Prospectus is required to be delivered under the Securities Act or the Exchange Act in connection with the offering, such number of copies (including by electronic means, if so requested by the Underwriters, in addition to or in lieu of, paper copies) of the Prospectus (as amended or supplemented) as the Underwriters may reasonably request for the purposes contemplated by the Securities Act, the Securities Act Regulations, the Exchange Act or Exchange Act Regulations.

(f) If at any time after the date hereof any event shall occur or a condition shall exist as a result of which it is necessary, in the reasonable opinion of counsel for the Underwriters, which shall be communicated in writing by the Representatives to the Company, to amend or supplement the Prospectus in order to make the Prospectus not misleading in the light of the circumstances existing at the time it is delivered, the Company will promptly either (a) forthwith prepare and furnish to the Underwriters an amendment of or supplement to the Prospectus or (b) make an appropriate filing pursuant to Section 13, 14 or 15 of the Exchange Act, in each case, in form and substance reasonably satisfactory to counsel for the Underwriters, which will amend or supplement the Prospectus so that it will not include an untrue statement of a material fact or omit to state a material fact necessary in order to make the statements therein, in the light of the circumstances existing at the time it is delivered, not misleading. If at any time after the date hereof, an event occurs or a condition shall exist as a result of which the General Disclosure Package contains an untrue statement of a material fact or omits to state a material fact necessary in order to make the statements therein, in the light of the circumstances existing at the time it is used, not misleading, the Company will promptly notify the Representatives and will promptly amend or supplement in a manner reasonably satisfactory to the Representatives, at its own expense, the General Disclosure Package to eliminate or correct such untrue statement or omission. If at any time following issuance of an Issuer Free Writing Prospectus there occurred or occurs an event or development or there exists or shall exist a condition as a result of which such Issuer Free Writing Prospectus conflicted or would conflict with the information contained in the Registration Statement (or any other registration statement relating to the Notes) or the Prospectus or any preliminary prospectus or included or would include an untrue statement of a material fact or omitted or would omit to state a material fact necessary in order to make the statements therein, in the light of the circumstances prevailing at that subsequent time, not misleading, the Company will promptly notify the Representatives and will promptly amend or supplement, at its own expense, such Issuer Free Writing Prospectus to eliminate or correct such conflict, untrue statement or omission. The

Underwriters’ delivery of any such amendment or supplement shall not constitute a waiver of any of the conditions in Section 6 hereof.

(g) The Company represents and agrees that, unless it obtains the prior written consent of the Representatives, and each Underwriter agrees that, unless it obtains the prior consent of the Company, it has not made and will not make any offer relating to the Notes that would constitute an “issuer free writing prospectus”, as defined in Rule 433, or that would otherwise constitute a “free writing prospectus,” as defined in Rule 405, required to be filed with the Commission. Any such free writing prospectus consented to by the Company and the Representatives is hereinafter referred to as a “Permitted Free Writing Prospectus.” The Company represents that it has treated or agrees that it will treat each Permitted Free Writing Prospectus as an “issuer free writing prospectus,” as defined in Rule 433, and has complied and will comply with the requirements of Rule 433 applicable to any Permitted Free Writing Prospectus, including timely filing with the Commission where required, legending and record keeping.

(h) The Company will endeavor to qualify the Notes for offer and sale under the securities or Blue Sky laws of such jurisdictions as the Representatives shall reasonably request and to continue such qualification in effect so long as reasonably required for distribution of the Notes and to pay all fees and expenses (including fees and disbursements of counsel to the Underwriters) reasonably incurred in connection with such qualification; provided that the Company shall not be required to file a general consent to service of process in any jurisdiction.

(i) The Company will make generally available to its security holders and to the Representatives as soon as practicable but not later than 18 months after the effective date of the Registration Statement (as defined in Rule 158(c)) an earnings statement covering a period of at least twelve months beginning with the first fiscal quarter of the Company occurring after the effective date of the Registration Statement, which shall satisfy the provisions of Section 11(a) of the Securities Act and Rule 158 of the Commission promulgated thereunder.

(j) The Company will, so long as the Notes are outstanding, furnish to each Underwriter copies of all reports or other communications (financial or other) furnished to holders of Notes, and copies of any reports and financial statements furnished to or filed with the Commission or any national securities exchange, other than, in any such case, those filed with the Commission pursuant to EDGAR.

(k) The Company will use the net proceeds received by it from the sale of the Notes in the manner specified in the Prospectus under “Use of Proceeds”.

(l) The Company will use its best efforts to continue to meet the requirements to qualify as a REIT under the Code for the taxable year in which sales of the Notes are to occur, unless otherwise specified in the General Disclosure Package and the Prospectus.

(m) The Company will timely file any document which it is required to file pursuant to the Exchange Act prior to the termination of the offering of the Notes.

(n) If immediately prior to the third anniversary (the “Renewal Deadline”) of the initial effective date of the Registration Statement, any of the Notes remain unsold by the Underwriters, the Company will prior to the Renewal Deadline file, if it has not already done so and is eligible to do so, a new automatic shelf registration statement relating to the Notes, in a form reasonably satisfactory to the Representatives. If the Company is no longer eligible to file an automatic shelf registration statement, the Company will prior to the Renewal Deadline, if it has not already done so, file a new shelf registration statement relating to the Notes, in a form reasonably satisfactory to the Representatives, and will use its best efforts to cause such registration statement to be declared effective within 60 days after the Renewal Deadline. The Company will take all other action reasonably necessary or appropriate to permit the public offering and sale of the Notes to continue as contemplated in the expired registration statement relating to the Notes. References herein to the Registration Statement shall include such new automatic shelf registration statement or such new shelf registration statement, as the case may be.

(o) If at any time when Notes remain unsold by the Underwriters the Company receives from the Commission a notice pursuant to Rule 401(g)(2) or otherwise ceases to be eligible to use the automatic shelf registration statement form, the Company will (i) promptly notify the Representatives, (ii) promptly file a new registration statement or post-effective amendment on the proper form relating to the Notes, in a form reasonably satisfactory to the Representatives, (iii) use its best efforts to cause such registration statement or post-effective amendment to be declared effective and (iv) promptly notify the Representatives of such effectiveness. The Company will take all other action necessary or appropriate to permit the public offering and sale of the Notes to continue as contemplated in the registration statement that was the subject of the Rule 401(g)(2) notice or for which the Company has otherwise become ineligible. References herein to the Registration Statement shall include such new registration statement or post-effective amendment, as the case may be.

(p) The Company will pay all costs and expenses incident to the performance of its obligations hereunder, including without limiting the generality of the foregoing, all costs and expenses (i) incident to the preparation, issuance, execution, authentication and delivery of the Notes, including any expenses of the Trustee, (ii) incident to the preparation, printing and filing under the Securities Act of the Registration Statement, the Prospectus, any preliminary prospectus (including in each case all exhibits, amendments and supplements thereto) and any Issuer Free Writing Prospectus, (iii) incurred in connection with the registration or qualification of the Notes under the laws of such jurisdictions as the Representatives may designate (including reasonable fees of counsel for the Underwriters and their disbursements), (iv) related to any filing with the National Association of Securities Dealers, Inc., (v) in connection with the printing (including word processing and duplication costs) and delivery of this Agreement, any Preliminary and Supplemental Blue Sky Survey and the furnishing to the Underwriters and dealers of copies of the Registration Statement and the Prospectus, including mailing and shipping, as herein provided (vi) payable to rating agencies in connection with the rating of the

Notes and (vii) the costs and expenses (including without limitation any damages or other amounts payable in connection with legal or contractual liability) associated with the reforming of any contracts for sale of the Notes made by the Underwriters caused by a breach of the representation contained in the eighth paragraph of Section 4(a); except as provided in clause (iii) above or in Section 7 or in Section 9 hereof, the Company shall not be obligated to pay the fees of counsel for the Underwriters and their disbursements.

limited to the tax matters specifically covered thereby and that they have not addressed any other tax consequences.

(h) (i) Concurrently with the execution and delivery of this Agreement, Deloitte & Touche LLP shall have furnished to the Representatives a letter, dated the date of its delivery, addressed to the Underwriters and in form and substance satisfactory to the Representatives, confirming that they are an independent registered public accounting firm with respect to the Company as required by the Securities Act and with respect to the financial statements and certain financial and other statistical and numerical information contained in the Registration Statement, the General Disclosure Package and the Prospectus or incorporated by reference therein. Such letter shall contain information of the type customarily included in accountants’ comfort letters to underwriters; (ii) at the Closing Date, prior to payment for and delivery of the Notes, Deloitte & Touche LLP shall have furnished to the Representatives a letter, dated the date of its delivery, which shall confirm, on the basis of a review in accordance with the procedures set forth in such letter, that nothing has come to their attention during the period from the date of the letter referred to in the prior sentence to a date (specified in the letter) not more than three days prior to the Closing Date which would require any change in their letter dated the date hereof if it were required to be dated and delivered at the Closing Date.

(i) The Representatives shall have received on and as of the Closing Date an opinion of Sidley Austin LLP, counsel for the Underwriters, in form and substance satisfactory to the Representatives and a statement to the following effect: no facts have come to such counsel’s attention that have caused such counsel to believe that (i) the Registration Statement, at the time of filing of the Company’s 2006 Annual Report on Form 10-K, or as of the “new effective date” with respect to the Underwriters of the Notes pursuant to, and within the meaning of, Rule 430B(f)(2) of the Securities Act Regulations, 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; (ii) the General Disclosure Package, at the Applicable Time, included an untrue statement of a material fact or omitted to state a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading; or (iii) the Prospectus, as of its date or at the Closing Date, as the case may be, included or includes an untrue statement of a material fact or omitted or omits to state a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading; except in each case such counsel shall not be required to express any belief or make any statement with respect to the financial statements (including the notes) and supporting schedules, if any, thereto and other financial data contained or incorporated or deemed to be incorporated by reference therein or omitted therefrom.

In giving such opinion, Sidley Austin LLP may rely, as to all matters governed by the laws of jurisdictions other than the law of the State of New York, and the federal law of the United States, upon the opinions of counsel satisfactory to the Representatives and may rely on an opinion dated the Closing Date of Locke Liddell & Sapp LLP as to matters governed by the laws of the State of Texas. Such counsel may also state that, insofar as such opinion involves

factual matters, they have relied, to the extent they deem proper, upon certificates of officers of the Company and its Subsidiaries and certificates of public officials.

(j) On or prior to the Closing Date the Company shall have furnished to the Representatives such further certificates and documents confirming the representations and warranties contained herein and related matters as the Representatives shall reasonably request.

The opinions and certificates mentioned in this Agreement shall be deemed to be in compliance with the provisions hereof only if they are in all material respects satisfactory to the Representatives and counsel for the Underwriters.

7. The Company agrees to indemnify and hold harmless each Underwriter, their respective officers and directors, and each person, if any, who controls each Underwriter within the meaning of either Section 15 of the Securities Act or Section 20 of the Exchange Act, from and against any and all losses, claims, damages and liabilities (including without limitation the reasonable legal fees and other expenses (including expenses of investigation and settlement) incurred in connection with any suit, action or proceeding or any claim asserted) caused by any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement, including the Rule 430B Information, the General Disclosure Package, any Issuer Free Writing Prospectus or the Prospectus (as amended or supplemented if the Company shall have furnished any amendments or supplements thereto) or any preliminary prospectus, or caused by any omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, except insofar as such losses, claims, damages or liabilities are caused by any untrue statement or omission or alleged untrue statement or omission made in reliance upon and in conformity with information relating to the Underwriters furnished to the Company in writing by any Underwriter through the Representatives expressly for use therein.

Each Underwriter agrees to indemnify and hold harmless the Company, its trust managers, its officers who signed the Registration Statement and each person who controls the Company within the meaning of Section 15 of the Securities Act and Section 20 of the Exchange Act, to the same extent as the foregoing indemnity from the Company to the Underwriters, but only with reference to information relating to the Underwriters furnished to the Company in writing by any Underwriter through the Representatives expressly for use in the Registration Statement, including the Rule 430B Information, the General Disclosure Package, any Issuer Free Writing Prospectus or the Prospectus, or any amendment or supplement thereto, or any preliminary prospectus.

If any suit, action, proceeding (including any governmental or regulatory investigation), claim or demand shall be brought or asserted against any person in respect of which indemnity may be sought pursuant to either of the two preceding paragraphs, such person (the “Indemnified Person”) shall promptly notify the person against whom such indemnity may be sought (the “Indemnifying Person”) in writing, and the Indemnifying Person, upon request of the Indemnified Person, shall retain counsel satisfactory to the Indemnified Person to represent the Indemnified Person in such proceeding and shall pay the fees and expenses of such counsel related to such proceeding. In any such proceeding, any Indemnified Person shall have the right

to retain its own counsel, but the fees and expenses of such counsel shall be at the expense of such Indemnified Person unless (i) the Indemnifying Person and the Indemnified Person shall have mutually agreed to the contrary, (ii) the Indemnifying Person has failed within a reasonable time to retain counsel satisfactory to the Indemnified Person or (iii) the named parties in any such proceeding (including any impleaded parties) include both the Indemnifying Person and the Indemnified Person and representation of both parties by the same counsel would be inappropriate due to actual or potential differing interests between them. It is understood that the Indemnifying Person shall not, in connection with any proceeding or related proceeding in the same jurisdiction, be liable for the fees and expenses of more than one separate firm (in addition to any local counsel) for all Indemnified Persons, and that all such fees and expenses shall be reimbursed as they are incurred. Any such separate firm for the Underwriters, its officers, its directors and any such control persons of the Underwriters shall be designated in writing by the Representatives and any such separate firm for the Company, its trust managers, its officers who signed the Registration Statement and such control persons of the Company or authorized representatives shall be designated in writing by the Company. The Indemnifying Person shall not be liable for any settlement of any proceeding effected without its written consent, but if settled with such consent or if there be a final judgment for the plaintiff, the Indemnifying Person agrees to indemnify any Indemnified Person from and against any loss or liability by reason of such settlement or judgment. Notwithstanding the foregoing sentence, if at any time an Indemnified Person shall have requested an Indemnifying Person to reimburse the Indemnified Person for fees and expenses of counsel as contemplated by the third sentence of this paragraph, the Indemnifying Person agrees that it shall be liable for any settlement of any proceeding effected without its written consent if (i) such settlement is entered into more than 30 days after receipt by such Indemnifying Person of the aforesaid request and (ii) such Indemnifying Person shall not have reimbursed the Indemnified Person in accordance with such request prior to the date of such settlement. No Indemnifying Person shall, without the prior written consent of the Indemnified Person, effect any settlement of any pending or threatened proceeding in respect of which any Indemnified Person is or could have been a party and indemnity could have been sought hereunder by such Indemnified Person, unless such settlement (i) includes an unconditional release of such Indemnified Person from all liability on claims that are the subject matter of such proceeding and (ii) does not include a statement as to or an admission of fault, culpability or a failure to act by or on behalf of any Indemnified Person.

If the indemnification provided for in the first and second paragraphs of this Section 7 is unavailable to an Indemnified Person or insufficient in respect of any losses, claims, damages or liabilities referred to therein, then each Indemnifying Person under such paragraph, in lieu of indemnifying such Indemnified Person thereunder, shall contribute to the amount paid or payable by such Indemnified Person as a result of such losses, claims, damages or liabilities (i) in such proportion as is appropriate to reflect the relative benefits received by the Company on the one hand and the Underwriters on the other hand from the offering of the Notes or (ii) if the allocation provided by clause (i) above 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 on the one hand and the Underwriters on the other in connection with the statements or omissions that resulted in such losses, claims, damages or liabilities, as well as any other relevant equitable considerations. The relative benefits received by the Company on the one hand and the Underwriters on the other shall be deemed to be in the same respective proportions as the net proceeds from the offering of such Notes (before deducting

expenses) received by the Company and the total underwriting discounts and the commissions received by the Underwriters bear to the aggregate public offering price of the Notes. The relative fault of the Company on the one hand and the Underwriters on the other shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information supplied by the Company 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 and the Underwriters agree that it would not be just and equitable if contribution pursuant to this Section 7 were determined by pro rata allocation or by any other method of allocation that does not take account of the equitable considerations referred to in the immediately preceding paragraph. The amount paid or payable by an Indemnified Person as a result of the losses, claims, damages and liabilities referred to in the immediately preceding paragraph shall be deemed to include, subject to the limitations set forth above, any legal or other expenses incurred by such Indemnified Person in connection with investigating or defending any such action or claim. Notwithstanding the provisions of this Section 7, in no event shall the Underwriters be required to contribute any amount in excess of the amount by which the total price at which the Notes underwritten by it and distributed to the public were offered to the public exceeds the amount of any damages that such Underwriters have otherwise been required to pay by reason of 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.

The indemnity and contribution agreements contained in this Section 7 are in addition to any liability which the Indemnifying Persons may otherwise have to the Indemnified Persons referred to above.

The indemnity and contribution agreements contained in this Section 7 and the representations, warranties and covenants of the Company set forth in this Agreement shall remain operative and in full force and effect regardless of (i) any termination of this Agreement, (ii) any investigation made by or on behalf of an Underwriter, its officers or directors or any person controlling an Underwriter or by or on behalf of the Company, its officers or trust managers or any other person controlling the Company and (iii) acceptance of and payment for any of the Notes.

8. Notwithstanding anything herein contained, this Agreement may be terminated in the absolute discretion of the Representatives, by notice given to the Company, if after the execution and delivery of this Agreement and prior to the Closing Date (i) the Company shall have failed, refused or been unable, at or prior to the Closing Date, to perform any agreement on its part to be performed hereunder, (ii) any other condition of the Underwriters’ obligations hereunder is not fulfilled, (iii) there shall have occurred, since the respective dates as of which information is given in the Registration Statement, the General Disclosure Package and the Prospectus, any material adverse change or any development involving a prospective material adverse change in or affecting the condition, financial or otherwise, of the Company or the earnings, business affairs, properties, management or business prospects of the Company,

whether or not arising in the ordinary course of business, (iv) trading generally shall have been suspended or materially limited on or by the New York Stock Exchange, (v) trading of any securities of or guaranteed by the Company shall have been suspended on any exchange or in any over-the-counter market, (vi) a general moratorium on commercial banking activities in New York or Texas shall have been declared by either Federal, Texas or New York State authorities; or there shall have occurred a material disruption in commercial banking or securities settlement or clearance services in the United States, (vii) there has occurred any downgrading or notice of any intended or potential downgrading or any review or possible change that indicates anything other than a stable outlook in the rating of the Company’s debt securities by any “nationally recognized statistical rating organization” (as defined for purposes of Rule 436(g)(2) under the Securities Act) or (viii) there shall have occurred any outbreak or escalation of hostilities or act of terrorism involving the United States or the declaration by the United States of a national emergency or war or the occurrence of any other calamity or crisis or any change in financial, political or economic conditions in the United States that, in the reasonable judgment of the Representatives, is material and adverse and which, in the reasonable judgment of the Representatives, makes it impracticable or inadvisable to proceed with the offering, sale or delivery of the Notes.

9. If this Agreement shall be terminated by the Underwriters because of any failure or refusal on the part of the Company to comply with the terms or to fulfill any of the conditions of this Agreement, or if for any reason the Company shall be unable to perform its obligations under this Agreement or any condition of the Underwriters’ obligations cannot be fulfilled, the Company agrees to reimburse the Underwriters for all out-of-pocket expenses (including the reasonable fees and expenses of their counsel) reasonably incurred by the Underwriters in connection with this Agreement or the offering of Notes contemplated hereunder.

10. If one or more of the Underwriters shall fail at the Closing Date to purchase Notes which it or they are obligated to purchase under this Agreement (the “Defaulted Notes”), the Representatives shall have the right, within 24 hours thereafter, to make arrangements for one or more of the non-defaulting Underwriters, or any other underwriters, to purchase all, but not less than all, of the Defaulted Notes in such amounts as may be agreed upon and upon the terms herein set forth; if, however, the Representatives shall not have completed such arrangements within such 24-hour period; then

(i) if the aggregate principal amount of Defaulted Notes does not exceed 10% of the aggregate principal amount of the Notes, the non-defaulting Underwriters shall be obligated to purchase the full amount thereof, severally, in the proportions that their respective underwriting obligations hereunder bear to the underwriting obligations of all non-defaulting Underwriters, or

(ii) if the aggregate principal amount of Defaulted Notes exceeds 10% of the aggregate principal amount of the Notes, this Agreement shall terminate without liability on the part of any non-defaulting Underwriter and the Company.

No action taken pursuant to this Section 10 shall relieve any defaulting Underwriter from liability in respect of its default.

In the event of any such default which does not result in the termination of this Agreement, either the Representatives or the Company shall have the right to postpone the Closing Date for a period not exceeding seven days in order to effect any required changes in the Prospectus or in any other documents or arrangements.

11. The Company acknowledges and agrees that (i) the purchase and sale of the Notes pursuant to this Agreement, is an arm’s-length commercial transaction between the Company, on the one hand, and the several Underwriters, on the other hand, (ii) in connection with the offering contemplated hereby and the process leading to such transaction, each Underwriter is and has been acting solely as a principal and is not the agent or fiduciary of the Company or its shareholders, creditors, employees, or any other party, (iii) no Underwriter has assumed nor will assume an advisory or fiduciary responsibility in favor of the Company with respect to the offering contemplated hereby or the process leading thereto (irrespective of whether such Underwriter has advised or is currently advising the Company on other matters) and no Underwriter has any obligation to the Company with respect to the offering contemplated hereby except the obligations expressly set forth in this Agreement, (iv) the Underwriters and their affiliates may be engaged in a broad range of transactions that involve interests that differ from those of the Company, and (v) the Underwriters have not provided any legal, accounting, regulatory or tax advice with respect to the transaction contemplated hereby and the Company has consulted its own legal, accounting, regulatory and tax advisors to the extent they deemed appropriate.

12. This Agreement shall inure to the benefit of and be binding upon the Company, each Underwriter, any controlling persons referred to herein and their respective successors and assigns. Nothing expressed or mentioned in this Agreement is intended or shall be construed to give any other person, firm or corporation any legal or equitable right, remedy or claim under or in respect of this Agreement or any provision herein contained. No purchaser of Notes from any Underwriter shall be deemed to be a successor by reason merely of such purchase.

13. All notices and other communications hereunder shall be in writing and shall be deemed to have been duly given if mailed or transmitted by any standard form of telecommunication. Notices to the Underwriters shall be directed to the Representatives c/o Banc of America Securities LLC, 40 West 57^th Street, NY1-040-27-03, New York, NY 10019, Attention High Grade Transaction Management/Legal, and to J.P.
