The U.S. Underwriters may exercise the option to purchase the Option Shares at any time (but not more than once) on or before the thirtieth day following the date of this Agreement, by written notice from the U.S. Representatives to RMOC.

(xi) under the laws of Thailand, none of the shareholders of Thai Romo will be deemed to be resident, domiciled or carrying on any business activity in Thailand or subject to any taxes, imposts or duties as a result only of its status as a shareholder or its receipt of dividends paid out of petroleum busines under the Petroleum Income Tax Act No. 4 with respect to the shares of Thai Romo or as a result of the transactions contemplated by this Agreement, the Exchange Agreement or the Custodial Agreement, other than stamp duty of 0.1 percent on the transfer of Thai Romo shares if the share transfer documents have been signed in Thailand or signed outside of Thailand but brought into Thailand, provided that the exchange of the shares of Thai Romo under the Exchange Agreement is effected entirely outside of Thailand and between non-residents of Thailand; (xii) each of the Concession and the Designation is, to the best of such counsel's knowledge, in full force and effect and there are no discrepancies in the English translation of the official Thai Concession and the letter of Designation; (xiii) under the terms of the Concession and according to applicable Thai statutes, regulations, decrees, orders and official practices, Thai Romo, the Block Operator, the Tantawan Operator -21- and Sophonpanich are deemed to constitute the Concessionaire (the "Concessionaire") pursuant to the Concession and are deemed to have the status of a separate, independent and autonomous, juristic person for all purposes related to the Concession; (xiv) dividends or distributions, either in cash or any other form, paid on the shares of Thai Romo are not subject to any Thai withholding or other tax; (xv) the choice of New York law as the proper law of the Underwriting Agreement and the choice of Texas law as the proper law of the Exchange Agreement and the Custodial Agreement is enforceable under the Thai Conflict of Laws Act; (xvi) Thai Romo may be sued in its own name in the courts of Thailand, and under the laws of Thailand would not be entitled to claim for itself or its revenues or assets any immunity from suit, court jurisdiction, attachment in aid of execution of a judgment or prior to judgment, set off, execution of a judgment or any other legal process with respect to its obligations under the Concession or the Joint Operating Agreements; (xvii) upon the transfer by the Exchanging Securityholders of the Thai Romo Notes pursuant to the Exchange Agreement (assuming due execution and delivery of the Exchange Agreement by the parties thereto), Thai Romo will be released under Thai law from all of its obligations to such Exchanging Securityholders related to such Thai Romo Notes; (xviii) the parties signatory to the Exchange Agreement and the Custodial Agreement constitute all of the parties required to cause the Exchange to be legal, valid and binding under Thai law in accordance with the terms of the Exchange Agreement and the Custodial Agreement (assuming the due execution and delivery thereof by the parties thereto); the provisions of the Exchange Agreement and the Custodial Agreement are in proper form under Thai law to legally transfer to RMOC all of the shares of capital of Thai Romo held by the Exchanging Securityholders free and clear of any lien or encumbrance (except as described in Schedule B to the Exchange Agreement) and to effect the other transactions set forth in the Exchange Agreement and the Custodial Agreement (assuming the due execution and delivery thereof); the provisions of the Exchange Agreement and the Custodial Agreement are legally sufficient under Thai law to terminate all rights of the Exchanging Securityholders as securityholders of Thai Romo and to vest in RMOC good and marketable title, free and clear of any lien or encumbrance (except as described in Schedule B to the Exchange Agreement), to all of the shares of capital of Thai Romo, except for five shares of capital of Thai Romo that will be owned by five of the Exchanging Securityholders designated by RMOC; such ownership of the shares of capital of Thai Romo by RMOC and such Exchanging Securityholders does not violate any provision of Thai law, the Concession, the Designation, the Joint Operating Agreements, the Memorandum or Articles or the Thai Romo Stockholders Agreement and satisfies all legal requirements applicable to Thai Romo as a private limited company validly existing under Thai law; the Exchanging Securityholders will not have any rights (assuming the due execution and delivery of the Exchange Agreement) to receive any dividends or distributions or any payments with respect to any reserves of Thai Romo other than as described in the Prospectus; and no taxes, fees or payments are required to be paid by the Company under Thai law in connection with the transactions contemplated by the Exchange Agreement and the Custodial Agreement except as provided for therein; and (xix) to such counsel's knowledge, Thai Romo owns, possesses or has obtained all licenses, permits, certificates, consents, orders, approvals and other authorizations from, and has made all -22- declarations and filings with, all governmental authorities (including regulatory agencies), all self-regulatory organizations and all courts and other tribunals necessary to own or lease, as the case may be, and to operate its properties and to carry on its business as conducted as of the date hereof, and Thai Romo has not received any actual notice of any proceeding relating to revocation or modification of any such license, permit, certificate, consent, order, approval or other authorization, except as described in the Registration Statement and the Prospectus; and Thai Romo and, to the best of the counsel's knowledge, the Block Operator and the Tantawan Operator are in compliance with all laws and regulations relating to the conduct of its business as conducted as of the date of the Prospectus. Based upon such counsel's representation of Thai Romo and its affiliates and such counsel's knowledge of Thai law and official practices, such counsel has no reason to believe that Thai Romo has conducted or is conducting its business or operations otherwise than in accordance with the Memorandum and Articles, the Concession, the Designation and the Joint Operating Agreements, or that any waivers, agreements or understandings exist with respect to the matters contemplated therein except as set forth therein. Such counsel may state that such opinion is limited in all respects to the laws of Thailand and that such opinion is rendered for the benefit of the Underwriters at the request of Thai Romo and may be relied upon by the Underwriters in connection with the Exchange, the offering of the Shares and the other transactions referenced in such opinion. (h) on or prior to the Closing Date or Additional Closing Date, as the case may be, the Representatives shall have received such certificates from the chief operating officer and the chief financial officer of RMOC and such opinions, from counsel reasonably satisfactory to the Representatives, as the Representatives may reasonably request with respect to the following matters: (i) other than as set forth or contemplated in the Prospectus, there are no legal or governmental investigations, actions, suits or proceedings pending or threatened against or affecting RMOC or any of the Subsidiaries or any of their respective properties or to which RMOC or any of the Subsidiaries is or may be a party or to which any property of RMOC or any of the Subsidiaries is or may be the subject which, if determined adversely to RMOC or any of the Subsidiaries, could individually or in the aggregate have, or reasonably be expected to have, a material adverse effect on the general affairs, business, prospects, management, financial position, stockholders' equity or results of operations of RMOC and the Subsidiaries, taken as a whole; (ii) neither RMOC, RMEC, TRH nor Thai Romo is, or with the giving of notice or lapse of time or both would be, in violation of or in default under, its certificate of incorporation or bylaws (or, as to Thai Romo, its Memorandum and Articles), as amended, or any indenture, mortgage, deed of trust, loan agreement or other agreement or instrument to which RMOC, RMEC, TRH or Thai Romo is a party or by which it or any of them or any of their respective properties is bound, except for violations and defaults which individually and in the aggregate are not material to RMOC and the Subsidiaries, taken as a whole; the issuance and sale of the Shares being delivered on the Closing Date or the Additional Closing Date, as the case may be, and the performance by each of RMOC and RMEC of its obligations under this Agreement and the consummation of the transactions contemplated herein and under the Exchange Agreement and the Custodial Agreement will not result in a breach of any of the terms or provisions of, or constitute a default under, any indenture, mortgage, deed of trust, loan agreement or other agreement or instrument to which -23- RMOC, RMEC, TRH or Thai Romo is a party or by which RMOC, RMEC, TRH or Thai Romo is bound or to which any of the property or assets of RMOC, RMEC or TRH is subject; (iii) prior to giving effect to the Transactions, all of the shares of capital stock of RMEC were owned of record by the Principal Shareholders and Mr. Sidney F. Jones, and all of the shares of capital stock of TRH were owned of record by RMOC, in each case, free and clear of any liens or encumbrances within the meaning of the Uniform Commercial Code; and all of the outstanding shares of capital stock of RMEC and TRH, after giving effect to the Transactions, will be owned directly by RMOC, free and clear of any liens or encumbrances within the meaning of the Uniform Commercial Code; (iv) each of the Principal Shareholders has full legal right, power and authorization, and any consent or approval required by law, any court or any governmental agency or body, to sell, assign, transfer and deliver good and marketable title to the Exchange Securities, in the numbers and amounts shown on Schedule B to the Exchange Agreement, free and clear of any liens or encumbrances, other than the pledges described on Schedule B to the Exchange Agreement; and (v) the delivery of certificates for the Exchange Securities by the Principal Shareholders pursuant to the Exchange Agreement and the Custodial Agreement, in the numbers and amounts shown on Schedule B to the Exchange Agreement, will pass good and valid title to such Exchange Securities to RMOC free and clear of any liens or encumbrances, other than the pledges described on Schedule B to the Exchange Agreement. (i) on the effective date of the Registration Statement and the effective date of the most recently filed post-effective amendment to the Registration Statement and also on the Closing Date or Additional Closing Date, as the case may be, KPMG Peat Marwick LLP shall have furnished to you letters, dated the respective dates of delivery thereof, in form and substance reasonably satisfactory to you, containing statements and information of the type customarily included in accountants' "comfort letters" to underwriters with respect to the financial statements and certain financial information contained in the Registration Statement and the Prospectus; (j) the Representatives shall have received on and as of the Closing Date or Additional Closing Date, as the case may be, an opinion of Andrews & Kurth L.L.P., counsel to the Underwriters, with respect to the due authorization and valid issuance of the Shares, the Registration Statement, the Prospectus and other related matters as the Representatives may reasonably request, and such counsel shall have received such papers and information as they may reasonably request to enable them to pass upon such matters; (k) on or prior to the Closing Date or Additional Closing Date, as the case may be, RMOC, RMEC and each of the Principal Shareholders shall have furnished to the Representatives such further certificates and documents as the Representatives shall reasonably request; (l) the "lock-up" agreements, each substantially as set forth in Section 6(i) herein, between you and certain stockholders, officers and directors of the Company relating to sales and certain other dispositions of shares of Common Stock or certain other securities, delivered to you on or before the date hereof, shall be in full force and effect on the Closing Date or the Additional Closing Date, as the case may be; -24- (m) all the representations and warranties of the Principal Shareholders contained in this Agreement shall be true and correct, on and as of the date hereof and on and as of the Closing Date as if made on and as of the Closing Date, and you shall have received a certificate, dated the Closing Date and signed by or on behalf of the Principal Shareholders to the effect set forth in this Section 8(m) and in Section 8(l) hereof; the Transactions shall have been consummated and the Exchange Agreement and the Custodial Agreement shall be in full force and effect as executed and delivered as of the date hereof, without any change or modification by operation of law or otherwise; (n) the Exchanging Securityholders shall not have failed at or prior to the date hereof or the Closing Date to have performed or complied with any of their agreements contained in the Exchange Agreement or the Custodial Agreement and required to be performed or complied with by them at or prior to the date hereof or the Closing Date; at the Closing, RMOC shall have furnished "lock-up" letters in substantially in form and substance set out in Section 6(i) and to the reasonable satisfaction to the Representatives, duly executed from the persons referred to in Section 6(n); (o) neither RMOC nor any Subsidiary shall have, directly or indirectly, paid or delivered any fee, commission or other sum of money or item or property, however, characterized, to any finder, agent, government official or other party in the United States, Thailand or any other country, which is in any matter related to the business or operations of the Company, which the Company knows or has reason to believe to have been illegal under any federal, state or local laws of the United States, Thailand or any other country having jurisdiction; (p) RMOC will provide a bring-down letter from Ryder Scott on the Closing Date and the Additional Closing Date, as the case may be; (q) the Stockholders Agreement of Thai Romo shall have been terminated as of the Closing Date; and (r) as of the Closing Date and the Additional Closing Date, as the case may be, either (i) the lending commitment letter dated _____________________ from __________________ shall be in full force and effect on the terms set forth therein or (ii) definitive agreements shall have been executed and delivered with respect to such lending commitment, on the terms set forth in the lending commitment letter described in clause (i). 9. RMOC and each Principal Shareholder agree to indemnify and hold harmless each Underwriter 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, from and against any and all losses, claims, damages and liabilities (including, without limitation, the legal fees and other expenses incurred in connection with any suit, action or proceeding or any claim asserted) caused by any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement or the Prospectus (as amended or supplemented if RMOC shall have furnished any amendments or supplements thereto) or any preliminary prospectus, or caused by any omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, except insofar as such losses, claims, damages or liabilities are caused by any untrue statement or omission or alleged untrue statement or omission made in reliance upon and in conformity with information relating to any Underwriter furnished to RMOC in writing by such Underwriter through the Representatives expressly for use therein, and provided that such indemnity with respect to any preliminary prospectus shall not inure to the benefit of the Underwriter (or any person controlling the Underwriter) from whom the person asserting any such loss, claim, damage or liability -25- purchased the Shares which are the subject thereof if such person did not receive a copy of the Prospectus (or the Prospectus as amended and supplemented) at or prior to the confirmation of the sale of such Shares to such person in any case where such delivery is required by the Securities Act and the untrue statement or omission of a material fact contained in such preliminary prospectus was corrected in the Prospectus (or the Prospectus as amended or supplemented), provided that RMOC shall have delivered the Prospectus, as amended or supplemented, to the Underwriters on a timely basis to permit such delivery. Notwithstanding anything in this Agreement to the contrary, each of the Principal Shareholders' aggregate liability, which liability shall be several and not joint, under this Agreement, including under this Section 9, shall be limited to an amount equal to the gross (before deducting expenses) cash proceeds of $_______ and $_______, respectively, (an aggregate of $24.6 million) received by Messrs. Rutherford and Moran from the Transactions (as described in the Prospectus) pursuant to this Agreement, the Exchange Agreement and the other agreements related to the Transactions and shall be subject to the procedures set forth in this Section 9. Each Underwriter agrees, severally and not jointly, to indemnify and hold harmless RMOC, its directors and officers who sign the Registration Statement, each person who controls RMOC within the meaning of Section 15 of the Securities Act and Section 20 of the Exchange Act and the Principal Shareholders to the same extent as the foregoing indemnity from RMOC and the Principal Shareholders to each Underwriter, but only with reference to information relating to such Underwriter furnished to RMOC in writing by such Underwriter through the Representatives expressly for use in the Registration Statement, the Prospectus, any amendment or supplement thereto, or any preliminary prospectus. If any suit, action, proceeding (including any governmental or regulatory investigation), claim or demand shall be brought or asserted against any person in respect of which indemnity may be sought pursuant to either of the two preceding paragraphs, such person (the "Indemnified Person") shall promptly notify the person against whom such indemnity may be sought (the "Indemnifying Person") in writing, and the Indemnifying Person, upon request of the Indemnified Person, shall retain counsel reasonably satisfactory to the Indemnified Person to represent the Indemnified Person and any others the Indemnifying Person may designate in such proceeding and shall pay the fees and expenses of such counsel related to such proceeding. In any such proceeding, any Indemnified Person shall have the right to retain its own counsel, but the fees and expenses of such counsel shall be at the expense of such Indemnified Person unless (i) the Indemnifying Person and the Indemnified Person shall have mutually agreed to the contrary, (ii) the Indemnifying Person has failed within a reasonable time to retain counsel reasonably satisfactory to the Indemnified Person or (iii) the named parties in any such proceeding (including any impleaded parties) include both the Indemnifying Person and the Indemnified Person and representation of both parties by the same counsel would be inappropriate due to actual or potential materially differing interests between them. It is understood that the Indemnifying Person shall not, in connection with any proceeding or related proceeding in the same jurisdiction, be liable for the fees and expenses of more than one separate firm (in addition to any local counsel) for all Indemnified Persons, and that all such fees and expenses shall be reimbursed as they are incurred. Any such separate firm for the Underwriters and such control persons of Underwriters shall be designated in writing by J.P. Morgan Securities Inc. and any such separate firm for RMOC, its directors, its officers who sign the Registration Statement and such control persons of RMOC shall be designated in writing by RMOC. The Indemnifying Person shall not be liable for any settlement of any proceeding effected without its written consent, but if settled with such consent or if there be a final judgment for the plaintiff, the Indemnifying Person agrees to indemnify any Indemnified Person to the extent set forth herein from and against any loss or liability by reason of such settlement or judgment. Notwithstanding the foregoing sentence, if at any time an Indemnified Person shall have requested an Indemnifying Person to reimburse the Indemnified Person for fees and expenses of counsel as contemplated -26- by the second and third sentences of this paragraph, the Indemnifying Person agrees that it shall be liable for any settlement of any proceeding effected without its written consent if (i) such settlement is entered into more than 30 days after receipt by such Indemnifying Person of the aforesaid request and (ii) such Indemnifying Person shall not have reimbursed the Indemnified Person in accordance with such request (except as to any amounts contested in writing in good faith by such Indemnifying Person) prior to the date of such settlement. No Indemnifying Person shall, without the prior written consent of the Indemnified Person, effect any settlement of any pending or threatened proceeding in respect of which any Indemnified Person is or could have been a party and indemnity could have been sought hereunder by such Indemnified Person, unless such settlement includes an unconditional release of such Indemnified Person from all liability on claims that are the subject matter of such proceeding. If the indemnification provided for in the first and second paragraphs of this Section 9 is unavailable to an Indemnified Person in respect of any losses, claims, damages or liabilities referred to therein, then each Indemnifying Person under such paragraph, in lieu of indemnifying such Indemnified Person thereunder, shall contribute to the amount paid or payable by such Indemnified Person as a result of such losses, claims, damages or liabilities (i) in such proportion as is appropriate to reflect the relative benefits received by RMOC and the Principal Shareholders on the one hand and the Underwriters on the other hand from the offering of the Shares or (ii) if the allocation provided by clause (i) above is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to in clause (i) above but also the relative fault of RMOC and the Principal Shareholders on the one hand and the Underwriters on the other in connection with the statements or omissions that resulted in such losses, claims, damages or liabilities, as well as any other relevant equitable considerations. The relative benefits received by RMOC and the Principal Shareholders on the one hand and the Underwriters on the other shall be deemed to be in the same respective proportions as the net proceeds from the offering (before deducting expenses) received by RMOC and the Principal Shareholders and the total underwriting discounts and the 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 Shares. The relative fault of RMOC and the Principal Shareholders on the one hand and the Underwriters on the other shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information supplied by RMOC or the Principal Shareholders or by the Underwriters and the parties' relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. RMOC, the Principal Shareholders and the Underwriters agree that it would not be just and equitable if contribution pursuant to this Section 9 were determined by PRO RATA allocation (even if the Underwriters were treated as one entity for such purposes) or by any other method of allocation that does not take account of the equitable considerations referred to in the immediately preceding paragraph. The amount paid or payable by an Indemnified Person as a result of the losses, claims, damages and liabilities referred to in the immediately preceding paragraph shall be deemed to include, subject to the limitations set forth above, any legal or other expenses incurred by such Indemnified Person in connection with investigating or defending any such action or claim. Notwithstanding the provisions of this Section 9, in no event shall (i) an Underwriter be required to contribute any amount in excess of the amount by which (x) the total price at which the Shares underwritten by it and distributed to the public were offered to the public exceeds (y) 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 and (ii) a Principal Shareholder be required to contribute any amount in excess of the amount by which (x) the gross (before deducting expenses) cash proceeds received by the Principal Shareholder from the Transactions (as described in the Prospectus) pursuant to this Agreement, the -27- Exchange Agreement and the other agreements related to the Transactions exceeds (y) the aggregate amount the Principal Shareholder 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. The Underwriters' obligations to contribute pursuant to this Section 9 are several in proportion to the respective number of Shares set forth opposite their names in Schedules I and II hereto, and not joint. The remedies provided for in this Section 9 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. The indemnity and contribution agreements contained in this Section 9 and the representations and warranties of RMOC, RMEC and the Principal Shareholders set forth in this Agreement shall remain operative and in full force and effect regardless of (i) any termination of this Agreement, (ii) any investigation made by or on behalf of any Underwriter or any person controlling any Underwriter or by or on behalf of RMOC or RMEC, their officers or directors, any other person controlling RMOC or RMEC, any Principal Shareholder or any Exchanging Securityholder and (iii) acceptance of and payment for any of the Shares. 10. Notwithstanding anything herein contained, this Agreement (or the obligations of the several Underwriters with respect to the Option Shares) may be terminated in the absolute discretion of the Representatives, by notice given to RMOC, if after the execution and delivery of this Agreement and prior to the Closing Date (or, in the case of the Option Shares, prior to the Additional Closing Date) (i) trading generally shall have been suspended or materially limited on or by, as the case may be, any of the New York Stock Exchange or the American Stock Exchange, the National Association of Securities Dealers, Inc., the Nasdaq National Market or The London Stock Exchange, (ii) trading of any securities of or guaranteed by RMOC shall have been suspended on any exchange or in any over-the-counter market, (iii) a general moratorium on commercial banking activities in New York or London, by either federal, New York State or United Kingdom authorities shall have been declared, or (iv) there shall have occurred any outbreak or escalation of hostilities or any change in financial markets or any calamity or crisis that, in the judgment of the Representatives, is material and adverse and which, in the judgment of the Representatives, makes it impracticable to market the Shares being delivered at the Closing Date or the Additional Closing Date, as the case may be, on the terms and in the manner contemplated in the Prospectus. 11. This Agreement shall become effective upon the later of (x) execution and delivery hereof by the parties hereto and (y) release of notification of the effectiveness of the Registration Statement (or, if applicable, any post- effective amendment) by the Commission. If on the Closing Date or the Additional Closing Date, as the case may be, any one or more of the Underwriters shall fail or refuse to purchase Shares which it or they have agreed to purchase hereunder on such date, and the aggregate number of Shares which such defaulting Underwriter or Underwriters agreed but failed or refused to purchase is not more than one-tenth of the aggregate number of Shares to be purchased on such date, the other Underwriters shall be obligated severally in the proportions that the number of Shares set forth opposite their respective names in Schedules I and II bears to the aggregate number of Underwritten Shares set forth opposite the names of all such non-defaulting Underwriters, or in such other proportions as the Representatives may specify, to purchase the Shares which such defaulting Underwriter or Underwriters agreed but failed or refused to purchase on such date; PROVIDED that in no event -28- shall the number of Shares that any Underwriter has agreed to purchase pursuant to Section 1 be increased pursuant to this Section 11 by an amount in excess of one-ninth of such number of Shares without the written consent of such Underwriter. If on the Closing Date or the Additional Closing Date, as the case may be, any Underwriter or Underwriters shall fail or refuse to purchase Shares which it or they have agreed to purchase hereunder on such date, and the aggregate number of Shares with respect to which such default occurs is more than one-tenth of the aggregate number of Shares to be purchased on such date, and arrangements satisfactory to the Representatives and RMOC for the purchase of such Shares are not made within 36 hours after such default, this Agreement (or the obligations of the several U.S. Underwriters to purchase the Option Shares, as the case may be) shall terminate without liability on the part of any non-defaulting Underwriter or RMOC. In any such case either you or RMOC shall have the right to postpone the Closing Date (or, in the case of the Option Shares, the Additional Closing Date), but in no event for longer than seven days, in order that the required changes, if any, in the Registration Statement and in the Prospectus or in any other documents or arrangements may be effected. 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. 12. If this Agreement shall be terminated by the Underwriters, or any of them, because of any failure or refusal on the part of RMOC or the Principal Shareholders to comply with the terms or to fulfill any of the conditions of this Agreement, or if for any reason RMOC, RMEC or the Principal Shareholders shall be unable to perform its obligations under this Agreement or any condition of the Underwriters' obligations cannot be fulfilled (other than solely as a result of a breach by the Underwriters of this Agreement), RMOC and RMEC agree to 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 expenses of its counsel) reasonably incurred by such Underwriters in connection with this Agreement or the offering contemplated hereunder. 13. This Agreement shall inure to the benefit of and be binding upon RMOC, the Underwriters, each affiliate of any Underwriter which assists such Underwriter in the distribution of the Shares, any controlling persons referred to herein and the Principal Shareholders, and their respective successors and assigns. Nothing expressed or mentioned in this Agreement is intended or shall be construed to give any other person, firm or corporation any legal or equitable right, remedy or claim under or in respect of this Agreement or any provision herein contained. No purchaser of Shares from any Underwriter shall be deemed to be a successor by reason merely of such purchase. 14. Any action by the Underwriters hereunder may be taken by the Representatives jointly or by J.P. Morgan Securities Inc. alone on behalf of the Underwriters, and any such action taken by the Representatives jointly or by J.P. Morgan Securities Inc. alone shall be binding upon the Underwriters. All notices and other communications hereunder shall be in writing and shall be deemed to have been duly given if mailed or transmitted by any standard form of telecommunication. Notices to the Underwriters shall be given to the Representatives, c/o J.P.
