Any certificate signed by any officer or trustee of the Company or the Trust and delivered to the Representatives or to counsel for the Underwriters pursuant to this Agreement shall be deemed a representation and warranty by the Company or the Trust, as applicable, to each Underwriter as to the matters covered thereby.

2. Agreements to Sell and Purchase. The Trust hereby agrees to sell to the several Underwriters, and each Underwriter, upon the basis of the representations and warranties herein contained, but subject to the conditions hereinafter stated, agrees, severally and not jointly, to purchase from the Trust the respective numbers of Firm Units set forth in Schedule I hereto opposite its name at $[ ] per Unit (the “Purchase Price”).

On the basis of the representations and warranties contained in this Agreement, and subject to its terms and conditions, the Trust agrees to sell to the Underwriters the Additional Units, and the Underwriters shall have the right to purchase, severally and not jointly, up to [3,431,250] Additional Units. The price per Unit of any Additional Units purchased by the Underwriters shall be the Purchase Price, less an amount per Unit equal to any dividends or distributions declared by the Trust and payable on the Firm Units but not payable on the Additional Units. The Representatives may exercise this right on behalf of the Underwriters in whole or from time to time in part by giving written notice not later than 30 days after the date of the Prospectus. Any exercise notice shall specify the number of Additional Units to be purchased by the Underwriters and the date on which such Units are to be purchased. Each purchase date must be at least one business day after the written notice is given and may not be earlier than the closing date for the Firm Units nor later than ten business days after the date of such notice. Additional Units may be purchased as provided in Section 4 hereof solely for the purpose of covering over-allotments made in connection with the offering of the Firm Units. On

each day, if any, that Additional Units are to be purchased (an “Additional Closing Date”), each Underwriter agrees, severally and not jointly, to purchase the number of Additional Units (subject to such adjustments to eliminate fractional units as the Representatives may determine) that bears the same proportion to the total number of Additional Units to be purchased on such Additional Closing Date as the number of Firm Units set forth in Schedule I hereto opposite the name of such Underwriter bears to the total number of Firm Units.

It is further understood that up to five percent of the Firm Units (the “Directed Units”) will initially be reserved by the several Underwriters for offer and sale upon the terms and conditions to be set forth in the most recent Preliminary Prospectus and in accordance with the rules and regulations of the Financial Industry Regulatory Authority, Inc. (“FINRA”) to the officers and directors of the Company and certain other persons associated with the Company (each such person a “Directed Unit Participant”) who have heretofore delivered to Morgan Stanley offers to purchase Firm Units in form satisfactory to Morgan Stanley (such program, the “Directed Unit Program”) and that any allocation of such Firm Units among such persons will be made in accordance with timely directions received by Morgan Stanley from the Company; provided that under no circumstances will Morgan Stanley or any Underwriter be liable to the Trust or the Company or to any such person for any action taken or omitted in good faith in connection with such Directed Unit Program. It is further understood that any Directed Units not affirmatively reconfirmed for purchase by any participant in the Directed Unit Program by 9:00 a.m., New York City time, on the first business day following the date hereof or otherwise not purchased by such persons will be offered by the Underwriters to the public upon the terms and conditions set forth in the Prospectus.

3. Terms of Public Offering. The Trust and the Company are advised by the Representatives that the Underwriters propose to make a public offering of their respective portions of the Units as soon after the Registration Statement and this Agreement have become effective as in the Representatives’ judgment is advisable.

The place of closing for the Firm Units and the Initial Closing Date may be varied by agreement among the Representatives, the Trust and the Company. The Trust and the Company hereby acknowledge that circumstances under which the Representatives may provide notice to postpone the Initial Closing Date as originally scheduled include any determination by the Trust, the Company or the Representatives to recirculate to the public copies of an amended or supplemental Prospectus or a delay as contemplated by the provisions of Section 10 hereof.

Delivery to the Underwriters and payment for any Additional Units to be purchased by the Underwriters shall be made at the offices of Bracewell & Giuliani LLP, 711 Louisiana,

Houston, Texas 77002 at 9:00 a.m., Houston, Texas time, on each Additional Closing Date as shall be specified in a written notice or notices, from the Representatives on behalf of the Underwriters to the Company and the Trust (as described in Section 2 above).

Delivery of the Firm Units and of any Additional Units to be purchased hereunder shall be made through the facilities of The Depository Trust Company against payment of the purchase price therefor by wire transfer of immediately available funds to an account or accounts specified in writing, not later than the close of business on the business day next preceding the Initial Closing Date or the Additional Closing Date, as the case may be, by the Trust. Payment for the Firm Units sold by the Trust hereunder shall be delivered by the Representatives to the Trust. Payment for the Additional Units sold by the Trust hereunder, if any, shall be delivered by the Representatives to the Trust.

It is understood that the Representatives have been authorized, for their own accounts and the accounts of the Underwriters, to accept delivery of and receipt for, and make payment of the Purchase Price for the Firm Units and the Additional Units, if any, that the Underwriters have agreed to purchase. Morgan Stanley & Co. LLC and Raymond James & Associates, Inc., each individually and not as a Representative of the Underwriters, may, but shall not be obligated to, make payment for any Units to be purchased by any Underwriter whose funds shall not have been received by the Representatives by the Initial Closing Date or the Additional Closing Date, as the case may be, for the account of such Underwriter, but any such payment shall not relieve such Underwriter from any of its obligations under this Agreement.

(o) To furnish to you as early as practicable prior to each Closing Date, but not later than two business days prior thereto, a copy of the latest available unaudited interim and monthly consolidated financial statements, if any, of the Trust which have been read by the Trust’s independent registered public accountants, as stated in their letter to be furnished pursuant to Section 8(k) hereof.

6. Indemnity and Contribution.

(a) The Company and the Trust agree, jointly and severally, to indemnify and hold harmless each Underwriter, its partners, members, directors, employees and officers, its agents who participated in the distribution of the Units and each person, if any, who controls any Underwriter within the meaning of either Section 15 of the Securities Act or Section 20 of the Exchange Act and each affiliate of any Underwriter within the meaning of Rule 405 under the Securities Act from and against any and all losses, claims, damages and liabilities, including, without limitation, any reasonable legal or other expenses incurred in connection with defending or investigating any such action or claim (collectively, “Damages”) 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 thereof, any Preliminary Prospectus, the Time of Sale Information, any Issuer Free Writing Prospectus, any Company or Trust information that the Company or the Trust, respectively, has filed, or is required to file, pursuant to Rule 433(d) under the Securities Act, or the Prospectus or any amendment or supplement thereto, 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 (in the case of the Preliminary Prospectus, the Time of Sale Information,

any Issuer Free Writing Prospectus or the Prospectus or in any amendment or supplement thereto, in the light of the circumstances under which they were made) not misleading, except insofar as such losses, claims, damages or liabilities are caused by any such untrue statement or omission or alleged untrue statement or omission based upon information relating to any Underwriter furnished to the Company or the Trust in writing by such Underwriter through you expressly for use therein.

(b) Each Underwriter agrees, severally and not jointly, to indemnify and hold harmless the Company and the Trust, their respective trustees, directors, officers who sign the Registration Statement and each person, if any, who controls the Company or the Trust within the meaning of either Section 15 of the Securities Act or Section 20 of the Exchange Act to the same extent as the foregoing indemnity from the Company and Trust to such Underwriter, but only with reference to information relating to such Underwriter furnished to the Company or the Trust in writing by such Underwriter expressly for use in the Registration Statement, any Preliminary Prospectus, the Time of Sale Information, any Issuer Free Writing Prospectus or the Prospectus or any amendment or supplement thereto, which information consists solely of the following information in the Preliminary Prospectus and the Prospectus: the third, sixth, ninth and tenth paragraphs under “Underwriting.”

(c) In case any proceeding (including any governmental investigation) shall be instituted involving any person in respect of which indemnity may be sought pursuant to Section 6(a) or 6(b), such person (the “indemnified party”) shall promptly notify the person against whom such indemnity may be sought (the “indemnifying party”) in writing and the indemnifying party, upon request of the indemnified party, shall retain counsel reasonably satisfactory to the indemnified party to represent the indemnified party and any others the indemnifying party may designate in such proceeding and shall pay the fees and disbursements of such counsel related to such proceeding. In any such proceeding, any indemnified party 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 party unless (a) the indemnifying party and the indemnified party shall have mutually agreed to the retention of such counsel or (b) the named parties to any such proceeding (including any impleaded parties) include both the indemnifying party and the indemnified party 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 party shall not, in respect of the legal expenses of any indemnified party in connection with any proceeding or related proceedings 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 such indemnified parties and that all such fees and expenses shall be reimbursed as they are incurred. Such firm shall be designated in writing by the Representatives, in the case of parties indemnified pursuant to Section 6(a), and by the Company or the Trust, as applicable, in the case of parties indemnified pursuant to Section 6(b). The indemnifying party 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 party agrees to indemnify the indemnified party from and against any loss or liability by reason of such settlement or judgment, but in the case of a judgment only to the extent stated in Sections 6(a) and 6(b). Notwithstanding the foregoing 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 as contemplated by the second and third sentences of this paragraph, the indemnifying party 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 party of the aforesaid request and (ii) such indemnifying party shall not have reimbursed the indemnified party in accordance with such request prior to the date of such settlement. No indemnifying party shall, without the prior written consent of the indemnified party, effect any settlement of any pending or threatened proceeding in respect of which any indemnified party is or could have been a party and indemnity could have been sought hereunder by such indemnified party, unless such settlement includes an unconditional release of such indemnified party from all liability on claims that are the subject matter of such proceeding.

(d) Notwithstanding the foregoing, the Trust shall not be obligated to make any payments to an indemnified party under this Section 6 until the earlier to occur of the following: (a) with respect to a final, nonappealable judgment of a court of competent jurisdiction or a settlement agreement, the Company has not paid such indemnified party the amount owed within 90 days of the due date under such judgment or settlement, (ii) with respect to expenses, the Company has not paid such indemnified party the amount owed within 90 days of submission by the indemnified party for reimbursement of such expenses or (iii) the Company shall become the subject of any bankruptcy or insolvency proceedings or publicly declares its inability to pay its debts as they become due.

(e) To the extent the indemnification provided for in Section 6(a) or 6(b) is unavailable to an indemnified party or insufficient in respect of any losses, claims, damages or liabilities referred to therein, then each indemnifying party under such paragraph, in lieu of indemnifying such indemnified party thereunder, shall contribute to the amount paid or payable by such indemnified party 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 and the Trust, respectively, on the one hand and the Underwriters on the other hand from the offering of the Units or (ii) if the allocation provided by clause 6(e)(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 6(e)(i) above but also the relative fault of the Company and the Trust on the one hand and of the Underwriters on the other hand 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 and the Trust on the one hand and the Underwriters on the other hand in connection with the offering of the Units shall be deemed to be in the same respective proportions as the net proceeds from the offering (after deducting underwriting discounts and commissions but before deducting expenses) received by the Trust (which amount, for purposes of this Section 6(e), shall also be deemed received by the Company without duplication), and the total underwriting discounts and commissions received by the Underwriters, in each case as set forth in the table on the cover of the Prospectus, bear to the aggregate Public Offering Price of the Units; provided that, in the event that the Underwriters shall have purchased any Additional Units hereunder, any determination of the relative benefits received by the Company and the Trust on the one hand or the Underwriters on the other hand from the offering of the Units shall include the net proceeds (after deducting underwriting discounts and commissions but before deducting expenses) received by the Trust (which amount, for purposes of this Section 6(e), shall also be deemed received by the Company without duplication), and the underwriting discounts and commissions received by the Underwriters, from the sale of such Additional Units, in each case computed on the basis of the respective

amounts set forth in the second table in the section of the Prospectus entitled “Underwriting.” The relative fault of the Company or the Trust on the one hand and the Underwriters on the other hand 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 the Trust, on the one hand, or by the Underwriters, on the other hand, and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. The Underwriters’ respective obligations to contribute pursuant to this Section 6 are several in proportion to the respective number of Units they have purchased hereunder, and not joint.

(f) The Company, the Trust and the Underwriters agree that it would not be just or equitable if contribution pursuant to this Section 6 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 that does not take account of the equitable considerations referred to in Section 6(e). The amount paid or payable by an indemnified party as a result of the losses, claims, damages and liabilities referred to in Section 6(e) shall be deemed to include, subject to the limitations set forth above, any legal or other expenses reasonably incurred by such indemnified party in connection with investigating or defending any such action or claim. Notwithstanding the provisions of this Section 6, no Underwriter shall be required to contribute any amount in excess of the amount by which the total price at which the Units underwritten by it and distributed to the public were offered to the public exceeds the amount of any damages that such Underwriter has 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 remedies provided for in this Section 6 are not exclusive and shall not limit any rights or remedies which may otherwise be available to any indemnified party at law or in equity.

(g) The indemnity and contribution provisions contained in this Section 6 and the representations, warranties and other statements of the Company and the Trust contained in this Agreement shall remain operative and in full force and effect regardless of (a) any termination of this Agreement, (b) any investigation made by or on behalf of any Underwriter, any of its partners, members, directors or officers, its agents who participated in the distribution of the Units or any person controlling any Underwriter or any affiliate of any Underwriter or by or on behalf of the Company or the Trust, their respective trustees, officers or directors or any person controlling the Company or the Trust and (c) acceptance of and payment for any of the Units.

7. Directed Unit Program Indemnification.

(a) The Company agrees to indemnify and hold harmless Morgan Stanley, each person, if any, who controls Morgan Stanley within the meaning of either Section 15 of the Securities Act or Section 20 of the Exchange Act and each affiliate of Morgan Stanley within the meaning of Rule 405 of the Securities Act (“Morgan Stanley Entities”) from and against any and all Damages (i) caused by any untrue statement or alleged untrue statement of a material fact contained in any material prepared by or with the consent of the Company or the Trust for distribution to Directed Unit Program Participants in connection with the Directed Unit Program 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; (ii) caused by the failure of any Directed Unit Program Participant to pay for and accept delivery of Directed Units that the Directed Unit Program Participant agreed to purchase; or (iii) related to, arising out of, or in connection with the Directed Unit Program, other than losses, claims, damages or liabilities (or expenses relating thereto) that are finally judicially determined to have resulted from the bad faith or gross negligence of Morgan Stanley Entities.

(b) In case any proceeding (including any governmental investigation) shall be instituted involving any Morgan Stanley Entity in respect of which indemnity may be sought pursuant to Section 7, the Morgan Stanley Entity seeking indemnity, shall promptly notify the Company in writing and the Company, upon request of the Morgan Stanley Entity, shall retain counsel reasonably satisfactory to the Morgan Stanley Entity to represent the Morgan Stanley Entity and any others the Company may designate in such proceeding and shall pay the fees and disbursements of such counsel related to such proceeding. In any such proceeding, any Morgan Stanley Entity shall have the right to retain its own counsel, but the fees and expenses of such counsel shall be at the expense of such Morgan Stanley Entity unless (i) the Company shall have agreed to the retention of such counsel or (ii) the named parties to any such proceeding (including any impleaded parties) include the Company and the Morgan Stanley Entity, and representation of both parties by the same counsel would be inappropriate due to actual or potential differing interests between them. The Company shall not, in respect of the legal expenses of the Morgan Stanley Entities in connection with any proceeding or related proceedings 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 Morgan Stanley Entities. Any such separate firm for the Morgan Stanley Entities shall be designated in writing by Morgan Stanley. The Company 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 Company agrees to indemnify the Morgan Stanley Entities from and against any loss or liability by reason of such settlement or judgment. Notwithstanding the foregoing sentence, if at any time a Morgan Stanley Entity shall have requested the Company to reimburse it for fees and expenses of counsel as contemplated by the second and third sentences of this paragraph, the Company 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 the Company of the aforesaid request and (ii) the Company shall not have reimbursed the Morgan Stanley Entity in accordance with such request prior to the date of such settlement. The Company shall not, without the prior written consent of Morgan Stanley, effect any settlement of any pending or threatened proceeding in respect of which any Morgan Stanley Entity is or could have been a party and indemnity could have been sought hereunder by such Morgan Stanley Entity, unless such settlement includes an unconditional release of the Morgan Stanley Entities from all liability on claims that are the subject matter of such proceeding.

(c) To the extent the indemnification provided for in Section 7(a) is unavailable to a Morgan Stanley Entity or insufficient in respect of any losses, claims, damages or liabilities referred to therein, then the Company in lieu of indemnifying the Morgan Stanley Entity thereunder, shall contribute to the amount paid or payable by the Morgan Stanley Entity 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 Morgan Stanley Entities on the other hand from the offering of the Directed Units or (ii) if the allocation provided

by clause 7(c)(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 7(c)(i) above but also the relative fault of the Company on the one hand and of the Morgan Stanley Entities on the other hand in connection with any 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 Morgan Stanley Entities on the other hand in connection with the offering of the Directed Units shall be deemed to be in the same respective proportions as the net proceeds from the offering of the Directed Units (after deducting underwriting discounts and commissions but before deducting expenses) and the total underwriting discounts and commissions received by the Morgan Stanley Entities for the Directed Units, bear to the aggregate Public Offering Price of the Directed Units. If the loss, claim, damage or liability is caused by an untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact, the relative fault of the Company on the one hand and the Morgan Stanley Entities on the other hand shall be determined by reference to, among other things, whether the untrue or alleged untrue statement or the omission or alleged omission relates to information supplied by the Company or by the Morgan Stanley Entities and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission.

(d) The Company and the Morgan Stanley Entities agree that it would not be just or equitable if contribution pursuant to this Section 7 were determined by pro rata allocation (even if the Morgan Stanley Entities were treated as one entity for such purpose) or by any other method of allocation that does not take account of the equitable considerations referred to in Section 7(c). The amount paid or payable by the Morgan Stanley Entities 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 reasonably incurred by the Morgan Stanley Entities in connection with investigating or defending any such action or claim. Notwithstanding the provisions of this Section 7, no Morgan Stanley Entity shall be required to contribute any amount in excess of the amount by which the total price at which the Directed Units distributed to the public were offered to the public exceeds the amount of any damages that such Morgan Stanley Entity has otherwise been required to pay. The remedies provided for in this Section 7 are not exclusive and shall not limit any rights or remedies which may otherwise be available to any indemnified party at law or in equity.

(e) The indemnity and contribution provisions contained in this Section 7 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 any Morgan Stanley Entity, the Company, its officers or directors or any person controlling the Company, or the Trust, its trustee or any person controlling the Trust, and (iii) acceptance of and payment for any of the Directed Units.

(ii) the representations and warranties of the Trust contained in this Agreement are true and correct as of such Closing Date and that the Trust has complied with all of the agreements and satisfied all of the conditions on its part to be performed or satisfied hereunder on or before such Closing Date, in each case, in all material respects.

(l) You shall have received, on each of the date hereof and each Closing Date, a letter dated the date hereof or such Closing Date, respectively, in form and substance satisfactory to the Underwriters, from PricewaterhouseCoopers LLP, independent public accountants of the Trust and the Company, respectively, containing statements and information

(p) The Company and the Trust shall have furnished or caused to have been furnished to you such further certificates and documents as you shall have reasonably requested.

All such opinions, certificates, letters and other documents will be in compliance with the provisions hereof only if they are reasonably satisfactory in form and substance to you and your counsel.

The several obligations of the Underwriters to purchase Additional Units hereunder are subject to the satisfaction on and as of the Additional Closing Date of the conditions set forth in this Section 8, except that, if the Additional Closing Date is other than the Initial Closing Date, the certificates, opinions and letters referred to in this Section 8 shall be dated as of the Additional Closing Date and the opinions called for by paragraphs (f), (g), (h), (i), (j) and (k) shall be revised to reflect the sale of Additional Units.

If any of the conditions hereinabove provided for in this Section 8 shall not have been satisfied when and as required by this Agreement, this Agreement may be terminated by you by notifying the Company and the Trust of such termination in writing at or prior to such Closing Date, but you shall be entitled to waive any of such conditions.

9. Termination. The Underwriters may terminate this Agreement by notice given by you to the Company and the Trust, if after the execution and delivery of this Agreement and prior to the Initial Closing Date (i) trading generally shall have been suspended or materially limited on any of the New York Stock Exchange or the NASDAQ Global Market or minimum or maximum prices shall have been generally established on such exchange, or additional material governmental restrictions, not in force on the date of this Agreement, shall have been imposed on trading in securities generally by any such exchange or by order of the Commission or any court or other governmental authority, (ii) trading of any securities of the Company or the Trust shall have been suspended on any exchange or in any over-the-counter market, (iii) a material disruption in securities settlement, payment or clearance services in the United States shall have occurred, (iv) any moratorium on commercial banking activities shall have been declared by Federal or New York State authorities or (v) there shall have occurred any outbreak or escalation of hostilities, or any change in financial markets or any calamity or crisis that, in your judgment, is material and adverse and which, singly or together with any other event specified in this clause (v), makes it, in your judgment, impracticable or inadvisable to proceed with the offer, sale or delivery of the Units on the terms and in the manner contemplated in the Time of Sale Information or the Prospectus.

10. Effectiveness; Defaulting Underwriters. (a) This Agreement shall become effective upon the execution and delivery hereof by the parties hereto.

(b) If, on any Closing Date, any one or more of the Underwriters shall fail or refuse to purchase Units that it has or they have agreed to purchase hereunder on such date, and the aggregate number of Units which such defaulting Underwriter or Underwriters agreed but failed or refused to purchase is not more than one-tenth of the aggregate number of the Units to be purchased on such Closing Date, the other Underwriters shall be obligated severally in the proportions that the number of Firm Units set forth opposite their respective names in Schedule I bears to the aggregate number of Firm Units set forth opposite the names of all such non-defaulting Underwriters, or in such other proportions as you may specify, to purchase the Units which such defaulting Underwriter or Underwriters agreed but failed or refused to purchase on such date; provided that in no event shall the number of Units that any Underwriter has agreed to purchase pursuant to this Agreement be increased pursuant to this Section 10 by an amount in excess of one-ninth of such number of Units without the written consent of such Underwriter. If, on the Initial Closing Date, any Underwriter or Underwriters shall fail or refuse to purchase Firm Units and the aggregate number of Firm Units with respect to which such default occurs is more than one-tenth of the aggregate number of Firm Units to be purchased on such date, and arrangements satisfactory to you, the Trust and the Company for the purchase of such Firm Units are not made within 48 hours after such default, this Agreement shall terminate without liability on the part of any non-defaulting Underwriter, the Company or the Trust. In

any such case either you, the Trust or the Company shall have the right to postpone the Initial Closing Date, but in no event for longer than seven days, in order that the required changes, if any, in the Registration Statement, in the Time of Sale Information, in the Prospectus or in any other documents or arrangements may be effected. If, on an Additional Closing Date, any Underwriter or Underwriters shall fail or refuse to purchase Additional Units and the aggregate number of Additional Units with respect to which such default occurs is more than one-tenth of the aggregate number of Additional Units to be purchased on such Additional Closing Date, the non-defaulting Underwriters shall have the option to (i) terminate their obligation hereunder to purchase the Additional Units to be sold on such Additional Closing Date or (ii) purchase not less than the number of Additional Units that such non-defaulting Underwriters would have been obligated to purchase in the absence of such default. Any action taken under this paragraph shall not relieve any defaulting Underwriter from liability in respect of any default of such Underwriter under this Agreement.

11. Failure to Comply. If this Agreement shall be terminated by the Underwriters, or any of them, because of any failure or refusal on the part of the Company or the Trust to comply with the terms or to fulfill any of the conditions of this Agreement, or if for any reason the Company or the Trust shall be unable to perform its obligations under this Agreement, the Company will reimburse the Underwriters or such Underwriters as have so terminated this Agreement with respect to themselves, severally, for all out-of-pocket expenses (including the fees and disbursements of their counsel) reasonably incurred by such Underwriters in connection with this Agreement or the offering contemplated hereunder.

12. Entire Agreement. This Agreement, together with any contemporaneous written agreements and any prior written agreements (to the extent not superseded by this Agreement) that relate to the offering of the Units, represents the entire agreement between the Company, the Trust and the Underwriters with respect to the preparation of the Registration Statement, any Preliminary Prospectus, the Time of Sale Information, the Prospectus, the conduct of the offering, and the purchase and sale of the Units.

13. No Fiduciary Duty. Each of the Company and the Trust acknowledges that in connection with the offering of the Units: (a) the Underwriters have acted at arms length, are not agents of, and owe no fiduciary duties to, the Company, the Trust or any other person, (b) the Underwriters owe the Company and the Trust only those duties and obligations set forth in this Agreement and prior written agreements (to the extent not superseded by this Agreement), if any, and (c) the Underwriters may have interests that differ from those of the Company and the Trust. Each of the Company and the Trust waives to the full extent permitted by applicable law any claims it may have against the Underwriters arising from an alleged breach of fiduciary duty in connection with the offering of the Units.

14. Counterparts. This Agreement may be signed in two or more counterparts, each of which shall be an original, with the same effect as if the signatures thereto and hereto were upon the same instrument.

15. Applicable Law. This Agreement shall be governed by and construed in accordance with the internal laws of the State of New York.

16. Headings. The headings of the sections of this Agreement have been inserted for convenience of reference only and shall not be deemed a part of this Agreement.

17. Notices. All communications hereunder shall be in writing and effective only upon receipt and if to the Underwriters shall be delivered, mailed or sent to you in care of Morgan Stanley & Co. LLC, 1585 Broadway, New York, New York 10036, Attention: Equity Syndicate Desk, with a copy to the Legal Department, and (ii) Raymond James & Associates, Inc., 880 Carillon Parkway, St. Petersburg, Florida 33716, Attention: John Critchlow; and if to the Company shall be delivered, mailed or sent to Chesapeake Energy Corporation, 6100 North Western Avenue, Oklahoma City, Oklahoma 73118, Attention: Jennifer M. Grigsby; and if to the Trust shall be delivered, mailed or sent in care of The Bank of New York Mellon Trust Company, N.A., 919 Congress Avenue, Suite 500, Austin, Texas 78701, Attention: Michael J. Ulrich.

18. Patriot Act. In accordance with the requirements of the USA Patriot Act, the Underwriters are required to obtain, verify and record information that identifies their respective clients, including the Company and the Trust, which information may include the name and address of their respective clients, as well as other information that will allow the Underwriters to properly identify their respective clients.

Please confirm that the foregoing correctly sets forth the agreement among the Company, the Trust and the several Underwriters.

EXHIBIT A

FORM OF OPINION OF BRACEWELL & GIULIANI LLP

1. No consent, approval, authorization or order of, or filing with, any U.S. federal, New York, Delaware or Texas governmental agency or body or any court is required for (A) the execution, delivery and performance by the Trust and the Chesapeake Entities of the Operative Agreements to which the Trust or any of the Chesapeake Entities is a party, (B) the issuance and sale of the Offered Securities by the Trust or (C) compliance by the Trust and the Chesapeake Entities with the terms and provisions of the Operative Agreements to which the Trust or any of the Chesapeake Entities is a party, other than (A) for registration of the Trust Units under the Securities Act and consents required under the Exchange Act, and applicable state securities or “Blue Sky” laws in the State of Delaware, the State of New York, the State of Texas or the United States of America in connection with the purchase and distribution of the Units by the Underwriters, as to which counsel need not provide an opinion, (B) such consents that have been, or prior to the Initial Closing Date will be, obtained or made, or (C) such consents that, if not obtained, would not reasonably be expected to have, individually or in the aggregate, a Material Adverse Effect or materially impair the ability of the Trust or any of the Chesapeake Entities to consummate the Transactions.

2. None of (A) the execution, delivery and performance by the Trust and the Chesapeake Entities of the Operative Agreements to which the Trust or any of the Chesapeake Entities is a party, (B) the issuance and sale of the Offered Securities by the Trust or (C) compliance by the Trust and the Chesapeake Entities with the terms and provisions of the Operative Agreements to which the Trust or any of the Chesapeake Entities is a party, (1) will result in a violation of U.S. federal laws, the laws of the State of New York or the State of Texas, the Delaware General Corporation Law, the Delaware Limited Liability Company Act or the Delaware Limited Partnership Act, in each case, which are, in our experience, customarily applicable to securities offerings, (2) will result in a violation of any order of any governmental agency or body or any court having jurisdiction over the Trust or the Chesapeake Entities or any of their respective properties or (3) will result in a breach or violation of any of the terms and provisions of, or constitute a default under, any of the agreements or instruments filed as an exhibit to the Registration Statement or referenced as Exhibits 4.1 through 4.12, inclusive, Exhibits 10.1.1 through 10.1.15, inclusive, and Exhibits 10.2.2 through 10.3, inclusive, to the Company’s Annual Report on Form 10-K for the year ended December 31, 2010; and Exhibits 10.1.14 to the Company’s Quarterly Report on Form 10-Q for the quarterly period ended June 30, 2011, to which the Trust or any of the Chesapeake Entities is a party or by which the Trust or any of the Chesapeake Entities is bound or to which any of the properties of the Trust or the Chesapeake Entities is subject, except in the case of this clause (3) for such breaches, violations or defaults that would not reasonably be expected to have, individually or in the aggregate, a Material Adverse Effect or materially impair the ability of the Trust or any of the Chesapeake Entities to consummate the Transactions; provided, however, we express no opinion in this paragraph (ii) with respect to compliance with the anti-fraud provisions of federal or state securities laws, rules or regulations or any other state or federal anti-fraud statute, rule or regulation.

A-1

3. Assuming the due authorization, execution and delivery by the parties thereto, the Registration Rights Agreement and the Administrative Services Agreement constitute valid and legally binding agreements of the parties thereto, enforceable against each of them in accordance with its respective terms, subject to applicable bankruptcy, insolvency, fraudulent transfer, reorganization, moratorium and similar laws relating to or affecting creditors’ rights generally and by general principles of equity (regardless of whether such enforceability is considered in a proceeding in equity or at law).

4. The statements set forth in the Registration Statement, the Time of Sale Information and the Prospectus under the captions “The Trust,” “Description of the Royalty Interests,” “Description of the Trust Agreement,” “Description of the Trust Units,” “U.S. Federal Income Tax Considerations,” “ERISA Considerations,” and “The Underlying Properties—Regulation,” insofar as they purport to constitute summaries of provisions of federal statutes, rules and regulations, or of any specific agreement or instrument, constitute complete and accurate summaries thereof in all material respects; and the descriptions of the Offered Securities contained in the Registration Statement, the Time of Sale Information and the Prospectus under the captions “The Trust,” “Description of the Trust Agreement” and “Description of the Trust Units” constitute accurate summaries as to legal matters of the terms of the Offered Securities in all material respects.

5. To our knowledge, neither the filing of the Registration Statement nor the offering or sale of the Offered Securities as contemplated by the Underwriting Agreement gives rise to any rights for or relating to the registration of any Offered Securities or other securities of the Trust.

6. The Registration Statement was declared effective under the Securities Act as of [__], 2011; to our knowledge, no stop order suspending the effectiveness of the Registration Statement has been issued and no proceedings for that purpose have been instituted or threatened by the Commission; and any required filing of the Prospectus pursuant to Rule 424(b) under the Securities Act has been made in the manner and within the time period required by such Rule.

7. The Registration Statement, on the most recent Effective Date, and the Prospectus, when filed with the Commission pursuant to Rule 424(b) and as of the date hereof, appeared on their face to comply as to form, in all material respects, with the requirements of the Securities Act, except that, in each case, we express no opinion as to (i) any of the documents incorporated by reference in the Registration Statement or (ii) the financial statements and schedules and other financial and accounting data (including the notes thereto and auditors’ report thereon), the oil and gas reserve and related future net revenue data and the factual statements contained in the exhibits to the documents incorporated by reference therein, in each case included therein or incorporated by reference therein or excluded therefrom or included in or excluded from the exhibits to the documents incorporated by reference in the Registration Statement. To our knowledge, there are no contracts or documents of a character required to be described in the Registration Statement or the Prospectus or to be filed as exhibits to such Registration Statement which are not described and filed as required.

8. Neither the Trust, the Company nor any of its subsidiaries is, nor after giving effect to the offering and sale of the Offered Securities and the application of the net proceeds

from such sale by the Trust, the Company and its subsidiaries, as described in the Registration Statement, the Time of Sale Information and the Prospectus under the caption “Use of Proceeds,” will be, an “investment company” or a company “controlled by” an “investment company” or an “affiliated person” of, or “promoter” or “principal underwriter” for, an “investment” company within the meaning of the Investment Company Act of 1940, as amended.

9. The opinion letter of Bracewell & Giuliani LLP that is filed as Exhibit 8.1 to the Registration Statement is confirmed, and the Underwriters may rely upon such opinion letter as if it were addressed to them.

Whenever an opinion that is based in part on factual matters is made “to our knowledge,” we have relied to the extent we deem appropriate on certificates of officers (after the discussion of the contents thereof with such officers) of the Company or the Trustee as to the existence or nonexistence of the factual matters upon which such opinion is predicated. We have no reason to believe, however, that any such certificate is untrue or inaccurate in any material respect.

In rendering the foregoing opinions, we have relied, without independent investigation, upon the opinions to you of Commercial Law Group, P.C., Henry J. Hood, Richards, Layton & Finger, P.A. and Andrews Kurth LLP dated as of even date herewith. Our opinions are limited in all respects to federal laws of the United States of America, the laws of the State of New York and the State of Texas, the Delaware General Corporation Law, the Delaware Limited Liability Company Act and the Delaware Limited Partnership Act and, in reliance upon the opinion of Commercial Law Group, P.C., the laws of the State of Oklahoma. We express no opinion as to, and for the purposes of the opinions set forth herein, we have conducted no investigation of, the laws of any other jurisdiction. Furthermore, we express no opinion with respect to (i) any permits to own or operate any real or personal property or (ii) state or local tax statutes to which the Company or the Trust may be subject.

Because the primary purpose of our engagement was not to establish or confirm factual matters or financial or accounting matters and because of the wholly or partially non-legal character of many of the statements contained in the Registration Statement, the Time of Sale Information and the Prospectus and the documents incorporated by reference therein, we are not passing upon, have not independently verified and do not assume any responsibility for, the accuracy, completeness or fairness of the statements contained in the Registration Statement, the Time of Sale Information or the Prospectus or the documents incorporated by reference therein, except to the extent specified in paragraph (iii) above. Without limiting the foregoing, we assume no responsibility for, have not independently verified and have not been asked to comment on the accuracy, completeness or fairness of the financial statements and schedules or other financial and accounting data or oil and gas reserve and future net revenue data included in the Registration Statement, the Time of Sale Information or the Prospectus or the documents incorporated by reference therein, and we have not examined the accounting, financial or other records from which such financial statements and schedules, other financial and accounting data and oil and gas reserve and future net revenue data were derived. In addition, we are not experts with respect to any portion of the Registration Statement, the Time of Sale Information or the Prospectus. However, we have participated in conferences with officers and other representatives of the Trust and the Company, the independent registered public accounting firm and independent petroleum reserve engineers for the Trust and the Company, your representatives

A-3

and your counsel at which the contents of the Prospectus, the Time of Sale Information and the Registration Statement and related matters were discussed. Based upon such participation and review, and relying, to the extent we deemed appropriate, as to materiality upon the factual statements of officers and other representatives of the Trust and the Company and of your representatives, we advise you that no facts have come to our attention that have caused us to believe that (i) any part of the Registration Statement (other than the financial statements and schedules and other financial or accounting data (including the notes thereto and auditor’s report thereon), oil and gas reserve and related future net revenue data and the factual statements in the exhibits thereto or to the documents incorporated by reference therein, in each case included therein or incorporated therein by reference, as to which we have not been asked to comment), at the time such part became effective, 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 Time of Sale Information (other than the financial statements and schedules and other financial or accounting data (including the notes thereto and auditor’s report thereon), oil and gas reserve and related future net revenue data and the factual statements in the exhibits to the documents incorporated by reference therein or incorporated therein by reference, as to which we have not been asked to comment), as of the Time of Sale and as of the date of the Underwriting Agreement, contained an untrue statement of a material fact or omitted to state a material fact necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading, (iii) the Prospectus (other than the financial statements and schedules and other financial or accounting data (including the notes thereto and auditor’s report thereon), oil and gas reserve and related future net revenue data or the factual statements in the exhibits to the documents incorporated by reference therein, in each case included therein or incorporated therein by reference, as to which we have not been asked to comment), as of its date and as of the date hereof, 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, or (iv) any of the documents incorporated by reference in the Registration Statement (other than the financial statements and schedules and other financial or accounting data (including the notes thereto and auditor’s report thereon), oil and gas reserve and related future net revenue data and the factual statements in the exhibits thereto, in each case included therein or incorporated therein by reference, as to which we have not been asked to comment), at the time such Registration Statement became effective or such document was filed with the Commission (or the time of filing of an amendment, if so amended or deemed amended), as the case may be, did not comply as to form in all material respects with the requirements of the Securities Act or Exchange Act, as the case may be.

FORM OF OPINION OF COMMERCIAL LAW GROUP, P.C.

1. The Company is a corporation duly incorporated and validly existing in good standing under the laws of the State of Oklahoma, with full power and authority to own, lease and operate its properties and to conduct its business as described in the Registration Statement, the Time of Sale Information and the Prospectus (and any amendment or supplement thereto).

2. Each of Chesapeake Exploration and Assignee has been duly organized and is in good standing under the laws of the State of Oklahoma, with power and authority (corporate and other) to own its property and conduct its business as described in the Registration Statement, the Time of Sale Information and the Prospectus; except where failure to be so qualified would not reasonably be expected to individually or in the aggregate have a Material Adverse Effect; and, to the best of such counsel’s knowledge, the capital stock or similar equity interests of each of Chesapeake Exploration and Assignee owned by the Company, directly or through subsidiaries, is owned free from Liens.

3. Each of the Chesapeake Entities has all requisite power and authority to enter into each of the Operative Agreements to which it is a party.

4. The Trustee is not required to qualify to transact business or appoint an agent for service of process in the State of Oklahoma solely as a result of the Trust’s ownership of the Royalty Interests, and such ownership will not require the appointment of an ancillary trustee in the State of Oklahoma.

5. As of the Initial Closing Date, the Company, directly or through subsidiaries, owns 100% of the outstanding equity interests in Chesapeake Exploration and Assignee. All of such equity interests have been duly authorized and have been validly issued, and are fully paid and nonassessable.

6. The Term Conveyances have been duly authorized by Chesapeake Exploration and Assignee, and when duly executed by the proper officers, managers or members of Chesapeake Exploration and Assignee and delivered by Chesapeake Exploration to Assignee, will constitute valid and binding agreements of Chesapeake Exploration enforceable against Chesapeake Exploration in accordance with their terms, except as such enforceability may be limited by (i) bankruptcy, insolvency, fraudulent transfer, reorganization, moratorium and similar laws relating to or affecting creditors’ rights generally and by general principles of equity (regardless of whether such enforceability is considered in a proceeding in equity or at law) and (ii) public policy, applicable law relating to fiduciary duties and indemnification and an implied covenant of good faith and fair dealing. The forms of the Term Conveyances to be filed are adequate and sufficient under the laws of the State of Oklahoma to transfer title to the Term Royalties to the Assignee and are in proper form for recording in the State of Oklahoma. Upon execution and delivery of the Term Conveyances by Chesapeake Exploration and Assignee and

B-1

recordation thereof in the Office of the County Clerk in Washita County, Oklahoma where the Subject Interests are located, the Term Royalties should be treated as fully conveyed interests in real property under the laws of the State of Oklahoma. The warranty of title provided in Section 1.05 of the Term Conveyances is valid and enforceable under the laws of the State of Oklahoma. The recording of the Term Conveyances in the Office of the County Clerk in Washita County, Oklahoma where the Subject Interests are located will be sufficient to provide Assignee the protections afforded under the recordation laws of the State of Oklahoma and the Term Conveyances should not constitute executory contracts as such term is used in the federal bankruptcy code. The Company is not required to make any recordings or filings of the Term Conveyances under the laws of the State of Oklahoma other than those recordings or filings described herein.

7. The Assignment and Conveyance has been duly authorized by Assignee, and, when duly executed by the proper officers, managers or members of the Assignee and the Trust, and delivered by Assignee to the Trust, will constitute valid and binding agreements of Assignee enforceable against Assignee in accordance with its terms, except as such enforceability may be limited by (i) bankruptcy, insolvency, fraudulent transfer, reorganization, moratorium and similar laws relating to or affecting creditors’ rights generally and by general principles of equity (regardless of whether such enforceability is considered in a proceeding in equity or at law) and (ii) public policy, applicable law relating to fiduciary duties and indemnification and an implied covenant of good faith and fair dealing. The form of the Assignment and Conveyance to be filed is adequate and sufficient under the laws of the State of Oklahoma to transfer title to the Term Royalties to the Trust and are in proper form for recording in the State of Oklahoma. Upon execution and delivery of the Assignment and Conveyance by Assignee and Trustee and recordation thereof in the Office of the County Clerk in Washita County, Oklahoma where the Subject Interests are located, the Term Royalties should be treated as fully conveyed interests in real property under the laws of the State of Oklahoma. The warranty of title provided in Section 1 of the Assignment and Conveyance is valid and enforceable under the laws of the State of Oklahoma. The recording of the Assignment and Conveyance in the Office of the County Clerk in Washita County, Oklahoma where the Subject Interests are located will be sufficient to provide the Trust the protections afforded under the recordation laws of the State of Oklahoma and the Assignment and Conveyance should not constitute an executory contract as such term is used in the federal bankruptcy code. The Company is not required to make any recordings or filings of the Assignment and Conveyance under the laws of the State of Oklahoma other than those recordings or filings described herein.

8. The Perpetual Conveyances have been duly authorized by Chesapeake Exploration, and, when duly executed by the proper officers, managers or members of Chesapeake Exploration and the Trust, and delivered by Chesapeake Exploration to the Trust, will constitute valid and binding agreements of Chesapeake Exploration enforceable against Chesapeake Exploration in accordance with their terms, except as such enforceability may be limited by (i) bankruptcy, insolvency, fraudulent transfer, reorganization, moratorium and similar laws relating to or affecting creditors’ rights generally and by general principles of equity (regardless of whether such enforceability is considered in a proceeding in equity or at law) and (ii) public policy, applicable law relating to fiduciary duties and indemnification and an implied covenant of good faith and fair dealing. The forms of the Perpetual Conveyances to be filed are adequate and sufficient under the laws of the State of Oklahoma to transfer title to the Perpetual

B-2

Royalties to the Trust and are in proper form for recording in the State of Oklahoma. Upon execution and delivery of the Perpetual Conveyances by Chesapeake Exploration and Trustee and recordation thereof in the Office of the County Clerk in Washita County, Oklahoma where the Subject Interests are located, the Perpetual Royalties should be treated as fully conveyed interests in real property under the laws of the State of Oklahoma. The warranty of title provided in Section 1.04 of the Perpetual Conveyances is valid and enforceable under the laws of the State of Oklahoma. The recording of the Perpetual Conveyances in the Office of the County Clerk in Washita County, Oklahoma where the Subject Interests are located will be sufficient to provide the Trust the protections afforded under the recordation laws of the State of Oklahoma and the Perpetual Conveyances should not constitute executory contracts as such term is used in the federal bankruptcy code. The Company is not required to make any recordings or filings of the Perpetual Conveyances under the laws of the State of Oklahoma other than those recordings or filings described herein.

9. The Drilling Support Mortgage, when filed of record in the real estate records maintained by the County Clerk of Washita County, Oklahoma in which the properties covered thereby are located, will be effective to create, in favor of the Trust, a valid and enforceable lien on the right, title and interest of Chesapeake Exploration in and to that portion of the properties covered thereby constituting real property described therein and will be valid and enforceable in accordance with its terms. The form of the Drilling Support Mortgage complies with the laws of the State of Oklahoma relating to filing and recordation, and the recording of the Drilling Support Mortgage in the real estate records maintained by the County Clerk of Washita County, Oklahoma will be adequate and legally sufficient under the laws of the State of Oklahoma for the purposes intended to be accomplished thereby. Once the Drilling Support Mortgage is so filed and recorded, no further or subsequent filing or refiling will be necessary in the State of Oklahoma in order to continue the existence or perfection of the lien referred to in this paragraph.

10. No approval, authorization, consent or other action by, or filing with, any governmental authority of the State of Oklahoma is required on the part of any Chesapeake Entity in connection with the (i) offering, issuance or sale by the Trust of the Trust Units as described in the Registration Statement, the Time of Sale Information and the Prospectus, (ii) the execution, delivery and performance of the Operative Agreements by the Trust or any of the Chesapeake Entities party hereto and thereto, or (iii) the consummation by the Trust or any of the Chesapeake Entities of the transactions contemplated by the Transaction Documents to which the any of the Trust and the Chesapeake Entities are a party, other than (A) approvals, authorizations, consents or other actions required under state securities or “Blue Sky” laws in the State of Oklahoma in connection with the purchase and distribution of the Units by the Underwriters, as to which such counsel need not provide an opinion, (B) such approvals, authorizations, consents or other actions that have been, or prior to the Initial Closing Date will be, obtained or made or (C) such approvals, authorizations, consents or other actions that, if not obtained, would not reasonably be expected to have, individually or in the aggregate, a Material Adverse Effect or materially impair the ability of the Trust or any of the Chesapeake Entities to consummate the Transactions provided for in the Transaction Documents.

11. None of (i) the offering, issuance and sale of the Trust Units by the Trust, (ii) the execution, delivery and performance by the Trust and the Chesapeake Entities of the Operative

B-3

Agreements to which the Trust or any of the Chesapeake Entities are a party, or (iii) the consummation by the Trust and any of the Chesapeake Entities of the Transactions contemplated by the Transaction Documents to which any of the Trust and the Chesapeake Entities are a party (A) conflicts or will conflict with the organizational documents of the Company, Chesapeake Exploration and Chesapeake Operating, (B) will result in a breach or violation of any of the terms and provisions of, constitute a default under, or result in the imposition of a lien under, any of the agreements or instruments referenced as Exhibits 3.1.2 through 3.1.5, inclusive, and Exhibit 10.2.1 to the Company’s Annual Report on Form 10-K for the year ended December 31, 2010, or (C) violates or will violate any statute, law or regulation or any order, judgment, decree or injunction known to such counsel of any Oklahoma court or governmental agency or body directed to any of the Trust or Chesapeake Entities or any of their respective properties or assets in a proceeding to which any of them or their respective properties or assets is a party or is bound, except in the case of clauses (B) and (C) for any breach, default or violation that would not reasonably be expected to have a Material Adverse Effect or materially impair the ability of the Trust and the Chesapeake Entities to consummate the Transactions provided for in the Transaction Documents; provided, however, we express no opinion with respect to compliance with the provisions of (a) any securities laws, rules or regulations or (b) any anti-fraud statute, rule or regulation of the State of Oklahoma.

In rendering such opinion, such counsel may (i) rely in respect of matters of fact upon certificates of the Trustee and officers and other employees of the Chesapeake Entities and upon information obtained from public officials, (ii) assume that all documents submitted to them as originals are authentic, that all copies submitted to them conform to the originals thereof, and that the signatures on all documents examined by them are genuine, (iii) state that their opinion is limited to the laws of the State of Oklahoma, (v) state that they express no opinion with respect to (A) any permits to own or operate any real or personal property or (B) state or local tax statutes to which the Chesapeake Entities or the Trust may be subject, and (vi) with respect to the existence of any Lien for which a financing statement under the Uniform Commercial Code of any state is on file, such counsel’s opinion is based solely upon such counsel’s review of a specific search of the office of the County Clerk of Oklahoma County, Oklahoma (each of which shall be as of a date not more than 10 days prior to such Closing Date and shall be provided to counsel to the Underwriters).
