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

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

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

(f)            During the period in which copies of the Prospectus are to be delivered as provided in subsection (e) above, if any event occurs as a result of which the Prospectus as then amended or supplemented would include an untrue statement of a material fact or omit to state any material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading, or if for any reason it shall be necessary during such same period to amend the Registration Statement or amend or supplement the Prospectus to comply with the Securities Act or file any document which will be deemed an Incorporated Document in order to comply with the Exchange Act and the rules and regulations thereunder, forthwith to prepare, submit to the Underwriters, file with the Commission and deliver, without charge to the

13

Underwriters either (i) amendments or supplements to the Registration Statement or Prospectus so that the statements in the Registration Statement or Prospectus, as so amended or supplemented, will not be misleading or (ii) such amendments, supplements or documents which will effect such compliance.  Delivery by the Underwriters of any such amendments or supplements to the Prospectus or documents shall not constitute a waiver of any of the conditions set forth in Section 5 hereof.

(j)            Unless otherwise specified, to use all reasonable efforts to effect the listing of the Purchased Securities on the NYSE within thirty days after the Closing Date, subject to notice of issuance, and maintain such listing.

(k)           During the period of five years from the date hereof, to supply to the Representatives and to each other Underwriter who may so request in writing, copies of such financial statements and other periodic and special reports as the Corporation may from time to time distribute to the holders of any class of its securities registered under Section 12 of the Exchange Act and not filed on EDGAR and to make such financial statements and reports generally available to the Representatives and such Underwriters by filing them on EDGAR.

expenses incident to the performance of the obligations of the Corporation under this Agreement, including those relating to (i) the preparation, printing and filing of the Registration Statement and exhibits thereto, each Preliminary Prospectus, the Prospectus, any Issuer Free Writing Prospectus and any amendments or supplements thereto, and the printing of the Transaction Documents (including any Agreement Among Underwriters), (ii) the issuance, preparation and delivery of the Purchased Securities to the Underwriters, including the costs and expenses of the Depositary, any trustee, registrar, transfer agent and any agent thereof, including any reasonable fees and disbursements of counsel therefor, (iii) the registration or qualification of the Purchased Securities for offer and sale under the securities or “blue sky” laws of the various jurisdictions referred to in subsection (i) above, including the reasonable fees and disbursements of counsel for the Underwriters in connection therewith and the preparation and printing of legal investment and preliminary and supplementary “blue sky” memoranda, (iv) the furnishing to the Underwriters of copies of the Preliminary Prospectus, the Prospectus, any Issuer Free Writing Prospectus and any amendments or supplements thereto, and of the several documents required by this Section to be so furnished, including costs of shipping and mailing, (v) the listing of the Purchased Securities and Maximum Number of Conversion Shares on any securities exchange, (vi) the rating of the Purchased Securities by rating agencies, (vii) all expenses incurred by the Corporation in connection with any “road show” presentation to potential investors and (viii) the furnishing to the Underwriters of copies of all reports and information required by Section 6(k) above, including costs of shipping and mailing.

(p)           To effect and maintain the listing on the NYSE of a number of Conversion Shares equal to the Maximum Number of Conversion Shares.

7.             Indemnification.

(a)           The Corporation will indemnify and hold harmless each Underwriter, such Underwriter’s selling agents who have participated or are deemed to have participated in the distribution of the Purchased Securities, its affiliates (as defined in Rule 405 under the Securities Act) and each person, if any, who controls any Underwriter within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act, as follows:

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

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

(iii)          against any and all expense whatsoever, as incurred (including, subject to Section 7(c) hereof, the fees and disbursements of counsel chosen by the Underwriters), reasonably incurred in investigating, preparing or defending against any litigation, or any investigation or proceeding by any governmental agency or body, commenced or threatened, or any claim whatsoever based upon

16

any such untrue statement or omission, or any such alleged untrue statement or omission, to the extent that any such expense is not paid under (i) or (ii) above;

provided, however, that the indemnity set forth in this Section 7(a) shall not apply to any loss, liability, claim, damage or expense to the extent arising out of any untrue statement or omission or alleged untrue statement or omission made in reliance upon and in conformity with written information furnished to the Corporation by any Underwriter through the Representatives expressly for use in the Registration Statement, any Preliminary Prospectus or the Prospectus (or any amendment or supplement to such documents), or any Issuer Free Writing Prospectus, it being understood and agreed that the only such information furnished by any Underwriter consists of the information being described as such in Section 7(b) hereof.

(b)           Each Underwriter, severally in proportion to its respective purchase obligation and not jointly, agrees to indemnify and hold harmless the Corporation, the directors of the Corporation, the officers of the Corporation who signed the Registration Statement, and each person, if any, who controls the Corporation within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act, against any and all loss, liability, claim, damage and expense described in the indemnity contained in Section 7(a) above, as incurred, but only with respect to untrue statements or omissions, or alleged untrue statements or omissions, made in the Registration Statement, any Preliminary Prospectus or the Prospectus (or any amendment or supplement to such documents), or any Issuer Free Writing Prospectus, in reliance upon and in conformity with written information furnished to the Corporation by such Underwriter through the Representatives expressly for use in the Registration Statement, any Preliminary Prospectus or the Prospectus (or any amendment or supplement to such documents) or any Issuer Free Writing Prospectus, it being understood and agreed that the only such information consists of the following: (i) the information in the fifth paragraph under the caption “Underwriting” in the Prospectus concerning the terms of the offering of the Purchased Securities by the Underwriters; and (ii) the information in the fifteenth and sixteenth paragraphs under the caption “Underwriting” in the Prospectus concerning stabilization and short positions.

(c)           Each indemnified party shall give written notice as promptly as reasonably practicable to each indemnifying party of any action commenced against it in respect of which indemnity may be sought hereunder, but failure to so notify an indemnifying party shall not relieve such indemnifying party from any liability hereunder to the extent it is not materially prejudiced as a result thereof and in any event shall not relieve it from any liability which it may have otherwise than on account of this indemnity agreement.  In the case of parties indemnified pursuant to Section 7(a) above, counsel to the indemnified parties shall be selected by the Underwriters, and, in the case of parties indemnified pursuant to Section 7(b) above, counsel to the indemnified parties shall be selected by the Corporation, provided that if it so elects within a reasonable time after receipt of such notice, an indemnifying party, jointly with any other indemnifying parties receiving such notice, may assume the defense of such action with counsel chosen by it and approved by the indemnified parties defendant in such action, unless such indemnified parties reasonably object to such assumption on the ground that there may be legal defenses

17

available to them which are different from or in addition to those available to such indemnifying party.  If an indemnifying party assumes the defense of such action, the indemnifying parties shall not be liable for any fees and expenses of counsel for the indemnified parties incurred thereafter in connection with such action; provided, however, that the indemnifying party shall pay the fees and expenses of separate counsel for the indemnified party if (i) the indemnifying party has agreed to pay such fees and expenses or (ii) counsel for the indemnified party reasonably determines that representation of both the indemnifying party and the indemnified party by the same counsel would create a conflict of interest.  An indemnifying party may participate at its own expense in the defense of any such action; provided, however, that counsel to the indemnifying party shall not (except with the consent of the indemnified party) also be counsel to the indemnified party.  In no event shall the indemnifying parties be liable for fees and expenses of more than one counsel (in addition to any local counsel) separate from their own counsel for all indemnified parties in connection with any one action or separate but similar or related actions arising out of the same general allegations or circumstances.  No indemnifying party shall, without the prior written consent of the indemnified parties, settle or compromise or consent to the entry of any judgment with respect to any litigation, or any investigation or proceeding by any governmental agency or body, commenced or threatened, or any claim whatsoever in respect of which indemnification or contribution could be sought under this Section 7 or Section 8 hereof (whether or not the indemnified parties are actual or potential parties thereto), unless such settlement, compromise or consent (i) includes an unconditional release of each indemnified party from all liability arising out of such litigation, investigation, proceeding or claim and (ii) does not include a statement as to or an admission of fault, culpability or a failure to act by or on behalf of any indemnified party.

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

8.             Contribution.  If the indemnification provided for in Section 7 hereof is for any reason unavailable to or insufficient to hold harmless an indemnified party in respect of any losses, liabilities, claims, damages or expenses referred to therein, then each indemnifying party

18

shall contribute to the aggregate amount of such losses, liabilities, claims, damages and expenses incurred by such indemnified party, as incurred, (i) in such proportion as is appropriate to reflect the relative benefits received by the Corporation, on the one hand and the Underwriters on the other hand from the offering of the Purchased Securities pursuant to this Agreement or (ii) if the allocation provided by clause (i) is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to in clause (i) above but also the relative fault of the Corporation on the one hand and of the Underwriters on the other hand in connection with the statements or omissions which resulted in such losses, liabilities, claims, damages or expenses, as well as any other relevant equitable considerations.  The relative benefits received by the Corporation on the one hand and the Underwriters on the other hand in connection with the offering of the Purchased Securities pursuant to this Agreement shall be deemed to be in the same respective proportions as the total net proceeds from the offering of the Purchased Securities pursuant to this Agreement (before deducting expenses but after deducting the total underwriting commission received by the Underwriters) received by the Corporation and the total underwriting commission received by the Underwriters, in each case as set forth on the cover of the Prospectus, bear to the aggregate initial public offering price of the Purchased Securities as set forth on such cover.  The relative fault of the Corporation on the one hand and the Underwriters on the other hand shall be determined by reference to, among other things, whether any such untrue or alleged untrue statement of a material fact or omission or alleged omission to state a material fact relates to information supplied by the Corporation on the one hand or by the Underwriters on the other and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission.  The Corporation and the Underwriters agree that it would not be just and equitable if contribution pursuant to this Section 8 were determined by pro rata allocation (even if the Underwriters were treated as one entity for such purpose) or by any other method of allocation which does not take account of the equitable considerations referred to above in this Section 8.  The aggregate amount of losses, liabilities, claims, damages and expenses incurred by an indemnified party and referred to above in this Section 8 shall be deemed to include any legal or other expenses reasonably incurred by such indemnified party in investigating, preparing or defending against any litigation, or any investigation or proceeding by any governmental agency or body, commenced or threatened, or any claim whatsoever based upon any such untrue or alleged untrue statement or omission or alleged omission.  Notwithstanding the provisions of this Section 8, no Underwriter shall be required to contribute any amount in excess of the amount by which the total price at which the Purchased Securities underwritten by it and distributed to the public were offered to the public exceeds the amount of any damages which such Underwriter has otherwise been required to pay by reason of any such untrue or alleged untrue statement or omission or alleged omission.  No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation.  For purposes of this Section 8, each person, if any, who controls an Underwriter within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act shall have the same rights to contribution as such Underwriter; each director of the Corporation, each officer of the Corporation who signed the Registration Statement, and each person, if any, who controls the Corporation within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act shall have the same rights to contribution as the Corporation.  The various Underwriters’ respective obligations to contribute pursuant to this Section 8 are several in proportion to their respective underwriting obligations and not joint.

19

The obligations of the Corporation under this Section 8 shall be in addition to any liability which the Corporation may otherwise have.

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

If this Agreement is terminated pursuant to any of the provisions hereof, except as otherwise provided herein, the Corporation and shall not be under any liability to any Underwriter and no Underwriter shall be under any liability to the Corporation, except that (a) if this Agreement is terminated by the Representatives because of any failure or refusal on the part of the Corporation to comply with the terms of this Agreement or because any of the conditions contained in Section 5 of this Agreement, other than Section 5(i) or Sections 5(d)(i), (iii), (iv) or (v), have not been met, the Corporation will reimburse the Underwriters for all reasonable out-of-pocket expenses (including the reasonable fees and disbursement of their counsel) reasonably incurred by them and (b) no Underwriter who shall have failed or refused to purchase the Purchased Securities agreed to be purchased by it hereunder, without some reason sufficient hereunder to justify its cancellation or termination of its obligations hereunder, shall be relieved of liability to the Corporation or the other Underwriters for damages occasioned by its default.

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

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

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

In any such case, the Underwriters or the Corporation shall have the right to postpone the Closing Date for a period of not more than seven business days in order that necessary changes and arrangements may be effected.  If the aggregate number of Purchased Securities to be

20

purchased by such defaulting Underwriters shall exceed 10% of the total number of Purchase Securities, and neither the non-defaulting Underwriters nor the Corporation shall make arrangements pursuant to this Section 10 within the period stated for the purchase of the Purchased Securities which the defaulting Underwriter or Underwriters agreed to purchase, this Agreement shall terminate without liability on the part of any non-defaulting Underwriter and without liability on the part of the Corporation, except, in each case, as provided in Sections 6(l), 7, 8 and 9 hereof.  The provisions of this Section 10 shall not in any way affect the liability of any defaulting Underwriter to the Corporation or the non-defaulting Underwriters arising out of such default.  A substitute underwriter hereunder shall become an Underwriter for all purposes of this Agreement.

11.          Absence of Fiduciary Relationship.  The Corporation acknowledges and agrees that (i) the purchase and sale of the Purchased Securities pursuant to this Agreement is an arm’s-length commercial transaction between the Corporation, on the one hand, and the Underwriters, on the other, (ii) in connection therewith and with the process leading to such transaction, each Underwriter is acting solely as a principal and not the agent or fiduciary of the Corporation, (iii) no Underwriter has assumed an advisory or fiduciary responsibility in favor of the Corporation with respect to the offering contemplated hereby or the process leading thereto (irrespective of whether such Underwriter has advised or is currently advising the Corporation on other matters) or any other obligation to the Corporation except the obligations expressly set forth in this Agreement, (iv) the Underwriters and their respective affiliates may have interests that differ from those of the Corporation and (v) the Corporation has consulted its own legal advisors to the extent it deemed appropriate.  The Corporation agrees that it will not claim that the Underwriters, or any of them, has rendered advisory services of any nature or respect, or owes a fiduciary or similar duty to the Corporation, in connection with such transaction or the process leading thereto.

12.          Miscellaneous.  The reimbursement, indemnification and contribution agreements contained in Sections 6(l), 7 and 8 hereof and the representations, warranties, covenants and agreements of the Corporation in this Agreement shall remain in full force and effect regardless of (a) any termination of this Agreement, (b) any investigation (or any statement as to the results thereof) made by or on behalf of any Underwriter or any officer, director or controlling person of any Underwriter, or by or on behalf of the Corporation, any officer or director of the Corporation or any controlling person of the Corporation, and (c) delivery of and payment for Purchased Securities under this Agreement.

In accordance with the requirements of the USA Patriot Act (Title III of Pub. L. 107-56 (signed into law October 26, 2001)), the Underwriters are required to obtain, verify and record information that identifies their respective clients, including the Corporation, 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.

This Agreement has been and is made solely for the benefit of the Underwriters, the Corporation and their respective permitted successors and assigns, and, to the extent expressed herein, for the benefit of persons controlling any of the Underwriters or the Corporation, and for the benefit of the directors and officers of the Corporation, and their respective successors and assigns, and no other person, partnership, association or corporation shall acquire or have any

21

right under or by virtue of this Agreement.  The term “successors and assigns” shall not include any purchaser of Purchased Securities merely because of such purchase.

This Agreement supersedes all prior agreements and understandings (whether written or oral) between the Corporation and the Underwriters, or any of them, with respect to the subject matter hereof.

The Corporation and each of the Underwriters hereby irrevocably waives, to the fullest extent permitted by applicable law, any and all right to trial by jury in any legal proceeding arising out of or relating to this Agreement or the transactions contemplated hereby.

This Agreement may be executed in two or more counterparts, each of which shall be deemed an original, but all of which together shall constitute one and the same instrument.  Facsimile copies or “PDF” or similar electronic data format copies of signatures shall constitute original signatures for all purposes of this Agreement and any enforcement hereof.

THIS AGREEMENT SHALL BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH, THE LAWS OF THE STATE OF NEW YORK.

(xii)         The Corporation is not subject to regulation as an “investment company” as such term is defined in the Investment Company Act of 1940, as amended.

In rendering such opinion, such counsel may state that such opinion is based on and limited to the relevant federal law of the United States of America, the law of the State of Texas, the law of the State of New York and the General Corporation Law of the State of Delaware, and that they render no opinion with respect to the state securities or “blue sky” laws of any jurisdiction or the law of any other jurisdiction. Such counsel may note that they are not admitted to the practice of law in the State of Delaware. With respect to the opinion expressed in the first clause of paragraph (i), such counsel may state that they have relied exclusively on certificiates of public officials.  With respect to paragraph (x), such counsel may also state that they render no opinion with respect to the anti-fraud provisions of the federal securities laws.

Such counsel may state that whenever its opinion is based on factual matters that are “to its knowledge after due inquiry” or “of which it has knowledge after due inquiry,” such counsel has, with your concurrence, relied to the extent such counsel deemed appropriate on certificates of officers (after the discussion of the contents thereof with such officers) of the Corporation, or certificates of others as to the existence or nonexistence of the factual matters upon which such opinion is predicated.  Such counsel shall state that it has no reason to believe, however, that any such certificate is untrue or inaccurate in any material respect.

Such counsel may also state that, because the primary purpose of such counsel’s engagement was not to establish or confirm factual matters or financial or accounting matters or matters pertaining to natural resource reserves and because of the wholly or partially non-legal character of many of the statements contained in the Registration Statement, the Pricing Disclosure Package (as defined in Annex A) and the Prospectus, as amended or supplemented prior to the date of such opinion, such counsel is not passing upon and does not assume any responsibility for the accuracy, completeness or fairness of the statements contained in the Registration Statement, the Pricing Disclosure Package or the Prospectus, as amended or supplemented prior to the date of such opinion (except to the extent expressly set forth in clause (b) of paragraph (iii) above and clause (b) of paragraph (iv) above), and they have not independently verified the accuracy, completeness or fairness of such statements (except as

II-3

aforesaid); that, without limiting the foregoing, they 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 notes thereto, schedules and related data and other financial or accounting data or information pertaining to natural resource reserves included in the Registration Statement, the Pricing Disclosure Package, the Prospectus, as amended or supplemented prior to the date of such opinion, or the exhibits to the Registration Statement, and they have not examined the accounting, financial or other records from which such financial statements and notes thereto, schedules and related data and other financial or accounting data or information pertaining to natural resource reserves contained therein were derived; and that, although certain portions of the Registration Statement have been included therein on the authority of “experts” within the meaning of the Securities Act, they are not experts with respect to any portion of the Registration Statement, including, without limitation, such financial statements and notes thereto, schedules and related data and other financial or accounting data or information pertaining to natural resource reserves included therein; that such counsel did not participate in the preparation of the Incorporated Documents; however, they have participated in conferences with officers and other representatives of the Corporation, its auditors, and representatives of the Underwriters, including counsel for the Underwriters, at which the contents of the Registration Statement, the Pricing Disclosure Package and the Prospectus, as amended or supplemented prior to the date of such opinion, and related matters were discussed; and, based upon such participation and review, and relying as to materiality in part upon the factual statements of officers and other representatives of the Corporation and upon representatives of the Underwriters, no facts have come to their attention that have caused them to believe that the Registration Statement, at the time it 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, or that the Registration Statement, including any information included in the Prospectus which 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 of the Rules, at the effective date with respect to the Underwriters pursuant to Rule 430B(f)(2) of the Rules, contained an untrue statement of a material fact or omitted to state a material fact required to be stated therein or necessary to make the statements therein not misleading, or that the Prospectus, as amended or supplemented prior to the date of such opinion, as of the date the Prospectus was first amended or supplemented by an amendment or final prospectus supplement related to the Purchased Securities, or as of the date of such opinion, or that the Pricing Disclosure Package at the Applicable Time, contained or contains 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, it being understood that such counsel has not been asked to comment on, and such counsel expresses no belief with respect to, the financial statements and notes thereto, schedules and related data and other financial or accounting data or information pertaining to natural resource reserves or exhibits (including the Form T-1) contained or incorporated by reference in or omitted from the Registration Statement, the Pricing Disclosure Package, or the Prospectus, as amended or supplemented prior to the date of such opinion.

Such counsel may state that its opinion is solely for the benefit of the Underwriters pursuant to Section 5(h) of the Agreement, and may not be used or relied upon by the Underwriters in any other capacity or for any other purpose and may not be used or relied upon by any other person or entity for any purpose without such counsel’s express prior written

II-4

authorization. Such counsel may state that except for the use permitted therein, such opinion may not be quoted, circulated or published, in whole or in part, or otherwise referred to, filed with or furnished to any other person or entity, without such counsel’s express prior written authorization; that the opinion expressed therein is not an opinion with respect to matters of fact or a guarantee and should not be construed or relied on as such; that the opinion expressed therein is as of the date thereof, and such counsel expressly disclaims any responsibility to update such opinion after the date thereof; and that such opinion is strictly limited to the matters stated therein, and no other or more extensive opinion is intended, implied or to be inferred beyond the matters expressly stated therein.
