If the option is exercised as to all or any portion of the International Option Securities, each of the International Managers, acting severally and not jointly, will purchase that proportion of the total number of International Option Securities then being purchased which the number of Initial International Securities set forth in Schedule A opposite the name of such International Manager bears to the total number of Initial International Securities, subject in each case to such adjustments as the Global Coordinator in its discretion shall make to eliminate any sales or purchases of fractional shares. (c) Payment. Payment of the purchase price for, and delivery of certificates for, the Initial Securities shall be made at the offices of Vinson & Elkins L.L.P., 1001 Fannin, Suite 2300, Houston, Texas 77002, or at such other place as shall be agreed upon by the Global Coordinator and the Company, at 8:00 A.M. (Central time) on the third (fourth, if the pricing occurs after 4:30 P.M. (Eastern time) on any given day) business day after the date hereof (unless postponed in accordance with the provisions of Section 10), or such other time not later than ten business days after such date as shall be agreed upon by the Global Coordinator and the Company and the Selling Shareholders (such time and date of payment and delivery being herein called "Closing Time"). At the request of the Company, payment shall be made by wire transfer pursuant to written instructions provided to the Global Coordinator at least two business days prior to the Closing Time. In addition, in the event that any or all of the International Option Securities are purchased by the International Managers, payment of the purchase price for, and delivery of certificates for, such International Option Securities shall be made at the above-mentioned offices, or at such other place as shall be agreed upon by the Global Coordinator and the Company, on each Date of Delivery as specified in the notice from the Global Coordinator to the Company. Payment shall be made to the Company the Selling Shareholders by wire transfer of immediately available funds to bank accounts designated by the Company and the Custodian pursuant to each Selling Shareholder's Power of Attorney and Custody Agreement, as the case may be, against delivery to the Lead Managers for the respective accounts of the International Managers of certificates for the International Securities to be purchased by them. It is understood that each International Manager has authorized the Lead Managers, for its account, to accept delivery of, receipt for, and make payment of the purchase price for, the Initial International Securities and the International Option Securities, if any, which it has agreed to purchase. Merrill Lynch, individually -12- 13 and not as representative of the International Managers, may (but shall not be obligated to) make payment of the purchase price for the Initial International Securities or the International Option Securities, if any, to be purchased by any International Manager whose funds have not been received by the Closing Time or the relevant Date of Delivery, as the case may be, but such payment shall not relieve such International Manager from its obligations hereunder.

In addition, each Selling Shareholder, severally and not jointly, agrees to indemnify and hold harmless each International Manager and each person, if any, who controls any International Manager within the meaning of Section 15 of the 1933 Act or Section 20 of the 1934 Act as follows: (i) against any and all loss, liability, claim, damage and expense whatsoever, as incurred, arising out of any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement (or any amendment thereto), including the Rule -19- 20 430A Information and the Rule 434 Information, if applicable, 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 included in any preliminary prospectus or the Prospectuses (or any amendment or supplement thereto), 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 6(d) below) any such settlement is effected with the written consent of the Company and the Selling Shareholders; and (iii) against any and all expense whatsoever, as incurred (including the fees and disbursements of counsel chosen by Merrill Lynch), reasonably incurred in investigating, preparing or defending against any litigation, or any investigation or proceeding by any governmental agency or body, commenced or threatened, or any claim whatsoever based upon any such untrue statement or omission, or any such alleged untrue statement or omission, to the extent that any such expense is not paid under (i) or (ii) above; provided, however; that each Selling Shareholder shall be obligated to indemnify and hold harmless each International Manager, and any person who controls such International Manager within the meaning of Section 15 of the 1933 Act or Section 20 of the 1934 Act, only to the extent such loss, liability, claim, damage or expense arises out of an untrue statement or omission or alleged untrue statement or omission of a material fact made in reliance upon and in conformity with written information furnished to the Company by such Selling Shareholder ("Shareholder Information") expressly for use in the Registration Statement (or any amendment thereto), including the Rule 430A Information and the Rule 434 Information, if applicable, or any preliminary prospectus or the International Prospectus (or any amendment or supplement thereto); and, provided further, that this indemnity agreement shall not apply to any loss, liability, claim, damage or expense to the extent arising out of any untrue statement or omission or alleged untrue statement or omission made in reliance upon and in conformity with written information furnished to the Company by any International Manager through Merrill Lynch International expressly for use in the Registration Statement (or any amendment thereto), including the Rule 430A Information and the Rule 434 Information, if applicable, or any preliminary prospectus or the International Prospectus (or any amendment or supplement thereto). The foregoing indemnity with respect to any untrue statement contained in or omission from a preliminary prospectus shall not inure to the benefit of any International Manager (or any person controlling such International Manager) from whom the person asserting any such loss, liability, claim, damage or expense purchased any of the International Securities which are the subject thereof if the Company or the Selling Shareholder shall sustain the burden of proving any such loss, liability, claim, damage or expense resulted from the fact that such person was not sent or given a copy of the International Prospectus (or the International Prospectus as amended or supplemented ) (in each case exclusive of the documents from which information is incorporated by reference) at or prior to the written confirmation of the sale of such International -20- 21 Securities to such person and (i) the Company has previously furnished copies thereof to the International Managers sufficiently in advance of the Closing Time to allow for distribution to the purchasers of the International Securities, and (ii) the loss, liability, claim, damage or expense resulted from an untrue statement contained in or omission from such preliminary prospectus that was corrected in the International Prospectus (or the International Prospectus as amended or supplemented).

Each International Manager severally agrees to indemnify and hold harmless the Company, its directors, each of its officers who signed the Registration Statement, and each person, if any, who controls the Company within the meaning of Section 15 of the 1933 Act or Section 20 of the 1934 Act and each Selling Shareholder and each person, if any, who controls any Selling Shareholder within the meaning of Section 15 of the 1933 Act or Section 20 of the 1934 Act against any and all loss, liability, claim, damage and expense described in the indemnity contained in subsection (a) of this Section, as incurred, but only with respect to untrue statements or omissions, or alleged untrue statements or omissions, made in the Registration Statement (or any amendment thereto), including the Rule 430A Information and the Rule 434 Information, if applicable, or any preliminary prospectus or the International Prospectus (or any amendment or supplement thereto) in reliance upon and in conformity with written information furnished to the Company by such International Manager through Merrill Lynch International expressly for use in the Registration Statement (or any amendment thereto), including the Rule 430A Information and the Rule 434 Information, if applicable, or such preliminary prospectus or the International Prospectus (or any amendment or supplement thereto). (c) Actions against Parties; Notification. Each indemnified party shall give 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 6(a) above, counsel to the indemnified parties shall be selected by Merrill Lynch, and, in the case of parties indemnified pursuant to Section 6(b) above, counsel to the indemnified parties shall be selected by the Company. 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. Notwithstanding the second preceding sentence, if it so elects within a reasonable time after receipt of such notice, an indemnifying party, jointly with any other indemnifying parties receiving such notice, may assume the defense of such action with counsel chosen by it and approved by the indemnified parties defendant in such action, unless such indemnified parties reasonably object to such assumption on the ground that there may be legal defenses available to them which are different from or in addition to those available to such indemnifying party. If an indemnifying party assumes the defense of such action, the indemnifying parties shall not be liable for any fees and expenses of counsel for the indemnified parties incurred thereafter in connection with such action. 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 -21- 22 any one action or separate but similar or related actions in the same jurisdiction 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 6 or Section 7 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) Settlement without Consent if Failure to Reimburse. If at any time an indemnified party shall have requested an indemnifying party to reimburse the indemnified party for fees and expenses of counsel, such indemnifying party agrees that it shall be liable for any settlement of the nature contemplated by Section 6(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. (e) Other Rights of Selling Shareholders. The provisions of this Section 6 shall not affect the rights of the Selling Shareholders to be indemnified by the Company, including, without limitation, those rights under the Company's Certificate of Incorporation, the GARI Registration Rights Agreement and the Series F Purchase Agreements. SECTION 7. Contribution. If the indemnification provided for in Section 6 hereof is for any reason unavailable to or insufficient to hold harmless an indemnified party in respect of any losses, liabilities, claims, damages or expenses referred to therein, then each indemnifying party shall contribute to the aggregate amount of such losses, liabilities, claims, damages and expenses incurred by such indemnified party, as incurred, (i) in such proportion as is appropriate to reflect the relative benefits received by the Company and the Selling Shareholders on the one hand and the International Managers on the other hand from the offering of the Securities pursuant to this Agreement or (ii) if the allocation provided by clause (i) is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to in clause (i) above but also the relative fault of the Company, each of the Selling Shareholders on the one hand and of the International Managers, as the case may be, 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; provided, however, a Selling Shareholder shall have an obligation to contribute only with respect to losses, liabilities, claims damages or expenses arising out of an untrue statement or omission or alleged untrue statement or omission of a material fact made in reliance upon and in conformity with Shareholder Information furnished by such Selling Shareholder. The relative benefits received by the Company and the Selling Shareholders on the one hand and the International Managers on the other hand in connection with the offering of the International 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 International Securities pursuant to this Agreement -22- 23 (before deducting expenses) received by the Company and the Selling Shareholders and the total underwriting discount received by the International Managers, in each case as set forth on the cover of the International Prospectus, or, if Rule 434 is used, the corresponding location on the Term Sheet, bear to the aggregate initial public offering price of the International Securities as set forth on such cover. The relative fault of the Company and the Selling Shareholders on the one hand and the International Managers on the other hand shall be determined by reference to, among other things, whether any such untrue or alleged untrue statement of a material fact or omission or alleged omission to state a material fact relates to information supplied by the Company or the Selling Shareholders or by the International Managers and the parties' relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. The Company, the Selling Shareholders and the International Managers agree that it would not be just and equitable if contribution pursuant to this Section 7 were determined by pro rata allocation (even if the International Managers 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 7. The aggregate amount of losses, liabilities, claims, damages and expenses incurred by an indemnified party and referred to above in this Section 7 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 7, each Selling Shareholder's aggregate liability pursuant to this Section 7 and Section 6 shall not exceed an amount equal to the net proceeds (before deducting expenses) received by such Selling Shareholder from the sale of the Securities pursuant to this Agreement. The Selling Shareholders respective obligations to contribute pursuant to this Section 7 are several and not joint. Notwithstanding the provisions of this Section 7, no International Manager shall be required to contribute any amount in excess of the amount by which the total price at which the International Securities underwritten by it and distributed to the public were offered to the public exceeds the amount of any damages which such International Manager 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 1933 Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. For purposes of this Section 7, each person, if any, who controls an International Manager within the meaning of Section 15 of the 1933 Act or Section 20 of the 1934 Act shall have the same rights to contribution as such International Manager, and each director of the Company, each officer of the Company who signed the Registration Statement, and each person, if any, who controls the Company or any Selling Shareholder within the meaning of Section 15 of the 1933 Act or Section -23- 24 20 of the 1934 Act shall have the same rights to contribution as the Company or such Selling Shareholder, as the case may be. The International Managers' respective obligations to contribute pursuant to this Section 7 are several in proportion to the number of Initial International Securities set forth opposite their respective names in Schedule A hereto and not joint. The provisions of this Section shall not affect any agreement or other obligation among the Company and any of the Selling Shareholders with respect to contribution, including, without limitation, those agreements and obligations under the Company's Certificate of Incorporation, the GARI Registration Rights Agreement and the Series F Purchase Agreements. SECTION 8. Representations, Warranties and Agreements to Survive Delivery. All representations, warranties and agreements contained in this Agreement or in certificates of officers of the Company or any of its subsidiaries or the Selling Shareholders submitted pursuant hereto, shall remain operative and in full force and effect, regardless of any investigation made by or on behalf of any International Manager or controlling person, or by or on behalf of the Company or the Selling Shareholders, and shall survive delivery of the Securities to the International Managers. SECTION 9. Termination of Agreement. (a) Termination; General. The Lead Managers may terminate this Agreement, by notice to the Company, at any time at or prior to Closing Time (i) if there has been, since the time of execution of this Agreement or since the respective dates as of which information is given in the International Prospectus, any material adverse change in the condition, financial or otherwise, or in the earnings, business affairs or business prospects of the Company and its subsidiaries considered as one enterprise, whether or not arising in the ordinary course of business, or (ii) if there has occurred any material adverse change in the financial markets in the United States or the international financial markets, any outbreak of hostilities or escalation thereof or other calamity or crisis or any change or development involving a prospective change in national or international political, financial or economic conditions, in each case the effect of which is such as to make it, in the judgment of the Lead Managers, impracticable to market the Securities or to enforce contracts for the sale of the Securities, or (iii) if trading in any securities of the Company has been suspended or materially limited by the Commission or the New York Stock Exchange, or if trading generally on the American Stock Exchange or the New York Stock Exchange or in the Nasdaq National Market has been suspended or materially limited, or minimum or maximum prices for trading have been fixed, or maximum ranges for prices have been required, by any of said exchanges or by such system or by order of the Commission, the National Association of Securities Dealers, Inc. or any other governmental authority, or (iv) if a banking moratorium has been declared by either Federal or New York authorities. (b) Liabilities. If this Agreement is terminated pursuant to this Section, such termination shall be without liability of any party to any other party except as provided in Section 4 hereof, and provided further that Sections 1, 6, 7 and 8 shall survive such termination and remain in full force and effect. SECTION 10. Default by One or More of the International Managers. If one or more of the International Managers shall fail at Closing Time or a Date of Delivery to purchase the Securities which it or they are obligated to purchase under this Agreement (the "Defaulted Securities"), the -24- 25 Lead Managers shall have the right, within 24 hours thereafter, to make arrangements for one or more of the non-defaulting International Managers, or any other underwriters, to purchase all, but not less than all, of the Defaulted Securities in such amounts as may be agreed upon and upon the terms herein set forth; if, however, the Lead Managers shall not have completed such arrangements within such 24-hour period, then: (a) if the number of Defaulted Securities does not exceed 10% of the number of International Securities to be purchased on such date, each of the non-defaulting International Managers shall be obligated, severally and not jointly, to purchase the full amount thereof in the proportions that their respective underwriting obligations hereunder bear to the underwriting obligations of all non-defaulting International Managers, or (b) if the number of Defaulted Securities exceeds 10% of the number of International Securities to be purchased on such date, this Agreement or, with respect to any Date of Delivery which occurs after the Closing Time, the obligation of the International Managers to purchase and of the Company to sell the Option Securities to be purchased and sold on such Date of Delivery shall terminate without liability on the part of any non-defaulting International Manager. No action taken pursuant to this Section shall relieve any defaulting International Manager from liability in respect of its default. In the event of any such default which does not result in a termination of this Agreement or, in the case of a Date of Delivery which is after the Closing Time, which does not result in a termination of the obligation of the International Managers to purchase and the Company to sell the relevant International Option Securities, as the case may be, either the Lead Managers or the Company and the Selling Shareholders shall have the right to postpone Closing Time or the relevant Date of Delivery, as the case may be, for a period not exceeding seven days in order to effect any required changes in the Registration Statement or Prospectus or in any other documents or arrangements. As used herein, the term "International Manager" includes any person substituted for an International Manager under this Section 10. SECTION 11. Default by one or more of the Selling Shareholders or the Company. (a) If one or more Selling Shareholders shall fail at Closing Time to sell and deliver the number of Securities which such Selling Shareholders are obligated to sell hereunder, and the remaining Selling Shareholders do not exercise the right hereby granted to increase, pro rata or otherwise, the number of Securities to be sold by them hereunder to the total number to be sold by all Selling Shareholders as set forth in Schedule B hereto, then the International Managers may, at the option of the Lead Managers, by notice from the Lead Managers to the Company and the non-defaulting Selling Shareholders, either (a) terminate this Agreement without any liability on the fault of any non-defaulting party except that the provisions of Sections 1, 4, 6, 7 and 8 shall remain in full force and effect or (b) elect to purchase the Securities which the non-defaulting Selling Shareholders and the Company have agreed to sell hereunder. No action taken pursuant to this Section 11 shall relieve any Selling Shareholder so defaulting from liability, if any, in respect of such default. In the event of a default by any Selling Shareholder as referred to in this Section 11, each of the Lead Managers and the Company and the non-defaulting Selling Shareholders shall have the -25- 26 right to postpone Closing Time for a period not exceeding seven days in order to effect any required change in the Registration Statement or Prospectus or in any other documents or arrangements. (b) If the Company shall fail at Closing Time or at the Date of Delivery to sell the number of Securities that it is obligated to sell hereunder, then this Agreement shall terminate without any liability on the part of any non-defaulting party; provided, however, that the provisions of Sections 1, 4, 6, 7, and 8 shall remain in full force and effect. No action taken pursuant to this Section shall relieve the Company from liability, if any, in respect of such default. SECTION 12. Notices. All notices and other communications hereunder shall be in writing and shall be deemed to have been duly given if mailed or transmitted by any standard form of telecommunication. Notices to the International Managers shall be directed to the Lead Managers at Ropemaker Place, 25 Ropemaker Street, London EC24 9L4, England, attention of Syndicate Department; and notices to the Company shall be directed to it at 1201 Louisiana, Suite 1400, Houston, Texas 77002, attention of Chief Executive Officer and to the Selling Shareholders to their Attorneys-in-Fact: John B.

This Agreement shall each inure to the benefit of and be binding upon the International Managers, the Company and the Selling Shareholders and their respective successors and assigns. Nothing expressed or mentioned in this Agreement is intended or shall be construed to give any person, firm or corporation, other than the International Managers, the Company and the Selling Shareholders and their respective successors and the controlling persons and officers and directors referred to in Sections 6 and 7 and their heirs and legal representatives, any legal or equitable right, remedy or claim under or in respect of this Agreement or any provision herein contained. This Agreement and all conditions and provisions hereof are intended to be for the sole and exclusive benefit of the International Managers, the Company and the Selling Shareholders and their respective successors, and said controlling persons and officers and directors and their heirs and legal representatives, and for the benefit of no other person, firm or corporation.

THIS AGREEMENT SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK. SPECIFIED TIMES OF DAY REFER TO NEW YORK CITY TIME, UNLESS OTHERWISE INDICATED. SECTION 15.

We inform you that we have participated in conferences with officers and other representatives of the Company and representatives of the independent public accountants for the Company and the Underwriters and representatives of legal counsel for the Underwriters, at which conferences the contents of the Registration Statement and the Prospectuses relating to the Company were discussed and, although we are not passing upon and do not assume any responsibility for and shall not be deemed to have independently verified the accuracy, completeness or fairness of the statements contained in the Registration Statement and the Prospectuses, on the basis of the foregoing (relying as to materiality to a large extent upon the opinions of officers and other representatives of the Company), no facts have come to our attention that would lead us to believe that the Registration Statement or any amendment thereto, including the Rule 430A Information and Rule 434 Information (if applicable), (except for financial statements and schedules (including the notes and auditors' reports thereon) and other financial data or reserve information included or incorporated by reference therein or omitted therefrom, as to which we need make no statement), at the time such Registration Statement or any such amendment 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 Prospectuses or any amendment or supplement thereto (except for financial statements and schedules (including the notes and auditors' reports thereon) and other financial data and reserve information included or incorporated by reference therein or omitted therefrom, as to which we need make no statement), at the time the A-3 36 Prospectuses were issued, at the time any such amended or supplemented prospectus was issued or at the Closing Time, 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. In rendering such opinion, such counsel may rely (A) as to matters involving the application of the laws of jurisdictions other than the State of Texas or New York, the Delaware General Corporation Law or United States federal laws on local counsel in such jurisdictions (which opinion shall be furnished to the U.S. Underwriters at the Closing Time and shall expressly state that the U.S. Underwriters may rely on such opinion as if it were addressed to them), provided that Akin, Gump, Strauss, Hauer & Feld, L.L.P. shall state in their opinion that they believe that they and the U.S. Underwriters are justified in relying upon such opinion, and (B), as to matters of fact (but not as to legal conclusions), to the extent they deem proper, on certificates of responsible officers of the Company and public officials. Such opinion shall not state that it is to be governed or qualified by, or that it is otherwise subject to, any treatise, written policy or other document relating to legal opinions, including, without limitation, the Legal Opinion Accord of the ABA Section of Business Law (1991). A-4 37 EXHIBIT B FORM OF OPINION OF COUNSEL FOR THE SELLING SHAREHOLDERS TO BE DELIVERED PURSUANT TO SECTION 5(c) (i) No filing with, or consent, approval, authorization, license, order, registration, qualification or decree of, any court or governmental authority or agency, domestic or foreign (other than the issuance of the order of the Commission declaring the Registration Statement effective and such authorizations, approvals or consents as may be necessary under state securities laws, as to which we need express no opinion) is necessary or required to be obtained by the Selling Shareholders for the performance by each Selling Shareholder of its obligations under the U.S. Purchase Agreement or the International Purchase Agreement or in the Power of Attorney and Custody Agreement, or in connection with the offer, sale or delivery of the Securities. (ii) Each Power of Attorney and Custody Agreement has been duly executed and delivered by the respective Selling Shareholders named therein and constitutes the legal, valid and binding agreement of such Selling Shareholder, subject to bankruptcy, insolvency, reorganization, fraudulent conveyance or transfer, moratorium or other similar laws affecting creditors' rights generally and general principals of equity (whether considered in a proceeding at law or in equity). (iii) The U.S. Purchase Agreement and the International Purchase Agreement have been duly authorized, executed and delivered by or on behalf of each Selling Shareholder. (iv) To our actual knowledge, each Selling Shareholder has good and valid title to the Securities to be sold by such Selling Shareholder pursuant to the U.S. Purchase Agreement and the International Purchase Agreement, free and clear of any pledge, lien, security interest, charge, claim, equity or encumbrance of any kind other than created pursuant to the U.S. Purchase Agreement, the International Purchase Agreement, Power of Attorney or Custody Agreement and has full right, power and authority to sell, transfer and deliver such Securities pursuant to the U.S. Purchase Agreement and the International Purchase Agreement. By delivery of a certificate or certificates therefor such Selling Shareholder will transfer to the Underwriters who have purchased such Securities pursuant to the U.S. Purchase Agreement and the International Purchase Agreement in good faith and without notice of any such pledge, lien, security interest, charge, claim, equity or encumbrance of any kind or any other adverse claim within the meaning of New York Uniform Commercial Code good and valid title to such Securities, free and clear of any pledge, lien, security interest, charge, claim, equity or encumbrance of any kind.
