THE TENDER OFFER

SECTION 2.01 The Tender Offer. (a) Provided that none of the events set forth in clauses (i) through (xi) of Annex D shall have occurred or be continuing, Purchaser shall commence the Tender Offer at a time satisfactory to it after the Effective Date; provided that at least five (5) Business Days’ notice shall have been provided to the Company. The obligation of Purchaser to accept for payment the Remaining Shares of the Preferred Stock tendered pursuant to the Tender Offer shall be subject to (i) the condition (the “Minimum Condition”) that at least such number of the Remaining Shares of Senior Preferred Stock and the Remaining Shares of Junior Preferred Stock, which, together with the shares of the Senior Preferred Stock and the Junior Preferred Stock to be purchased by Purchaser pursuant to the Senior Preferred Stock Purchase Agreements and the Junior Preferred Stock Purchase Agreement, represents at least 90% of the outstanding shares of each of the Senior Preferred Stock and Junior Preferred Stock, respectively, and (ii) the satisfaction of each of the other conditions set forth in Annex D hereto. Purchaser expressly reserves the right to waive any such condition (except as expressly provided otherwise in Annex D hereto), to increase the price per share payable in the Tender Offer, and to make any other changes in the terms and conditions of the Tender Offer; provided, however, that no change may be made which decreases the price per share payable in the Tender Offer or which imposes conditions to the Tender Offer in addition to those set forth in Annex D hereto. Notwithstanding the foregoing, Purchaser may, without the consent of the Company, extend the Tender Offer (i) for one or more periods of not more than 20 Business Days each beyond the scheduled expiration date, which initially shall be 20 Business Days following the commencement of the Tender Offer (the “Tender Offer Initial Expiration Date”), if, at any scheduled expiration of the Tender Offer, any of the conditions to Purchaser’s obligation to accept for payment the Remaining Shares of the Preferred Stock, shall not be satisfied or waived and (ii) for any period required by any rule, regulation or interpretation of the Securities and Exchange Commission (the “SEC”), or the staff thereof, or the American Stock Exchange (“AMEX”) applicable to the Tender Offer (any expiration time and date established pursuant to any extension of the Tender Offer under this Agreement, as so extended, the “Tender Offer Expiration Date”). Purchaser shall pay for all Remaining Shares of the Preferred Stock validly tendered and not withdrawn promptly following the acceptance of the Remaining Shares of the Preferred Stock for payment pursuant to the Tender Offer. Notwithstanding the immediately preceding sentence and subject to the applicable rules of the SEC and the terms and conditions of the Tender Offer, Purchaser expressly reserves the right to delay payment for the Remaining Shares of the Preferred Stock in order to comply in whole or in part with applicable Laws. Any such delay shall be effected in compliance with Rule 14e-1(c) under the Exchange Act. Purchaser may extend the Tender Offer after the acceptance of the Remaining Shares of the Preferred Stock thereunder for a further period of time by means of a subsequent offering period of not more than 20 Business Days to meet the objective that there be validly tendered, in accordance with the terms of the Tender Offer, prior to the expiration of the Tender Offer (as so extended), and not withdrawn a number of the Remaining Shares of Senior Preferred Stock and the Remaining Shares of Junior Preferred Stock, which, together with the shares of the Senior Preferred Stock and the shares of the Junior Preferred Stock to be purchased by Purchaser pursuant to the Senior Preferred Stock Purchase Agreements and the Junior Preferred Stock

If any payment of the Tender Offer Price is to be made to a Person other than the Person in whose name the surrendered certificate formerly evidencing the Preferred Stock is registered on the stock transfer books of the Company, it shall be a condition of payment that the certificate so surrendered shall be endorsed properly or otherwise be in proper form for transfer and that the Person requesting such payment shall have paid all transfer and other taxes required by reason of any payment of the Tender Offer Price to a Person other than the registered holder of the certificate surrendered, or shall have established to the satisfaction of Purchaser that such taxes either have been paid or are not applicable. No dividends, whether or not declared, will be paid by Purchaser on any shares of Preferred Stock tendered into the Tender Offer.

(b) Notwithstanding anything to the contrary in this Agreement, Purchaser may, in its sole discretion, provide the holders of the Remaining Shares of Senior Preferred Stock the right to receive, as an alternative to the per share cash consideration payable in the Tender Offer, Purchaser Convertible Bonds in exchange for the Remaining Shares of Senior Preferred Stock validly tendered and not withdrawn in the Tender Offer.

Each of Purchaser and the Company agrees to correct promptly any information provided by it for use in the Tender Offer Documents that shall have become false or misleading in any material respect, and Purchaser further agrees to take all steps necessary to cause the Tender Offer Documents, as so corrected, to be disseminated to holders of the Remaining Shares of the Preferred Stock and, if required, filed with the SEC, in each case as and to the extent required by applicable U.S. federal securities laws.

No Action is pending or, to the knowledge of the Company, threatened with respect to any Plan (other than claims for benefits in the ordinary course) and no fact or event exists that could give rise to any such Action.

(d) Each Plan that is intended to be qualified under Section 401(a) of the Code or Section 401(k) of the Code has timely received a favorable determination letter from the IRS covering all of the provisions applicable to the Plan for which determination letters are currently available that the Plan is so qualified and each trust established in connection with any Plan which is intended to be exempt from federal income taxation under Section 501(a) of the Code has received a determination letter from the IRS that it is so exempt, and no fact or event has occurred since the date of such determination letter or letters from the IRS to adversely affect the qualified status of any such Plan or the exempt status of any such trust.

(e) There has not been any prohibited transaction (within the meaning of Section 406 of ERISA or Section 4975 of the Code) with respect to any Plan.

Neither the Company nor any Subsidiary has been required to post any security under Section 307 of ERISA or Section 401(a)(29) of the Code. No fact or event exists that could give rise to such lien or requirement to post any such security.

(f) All contributions, premiums or payments required to be made with respect to any Plan have been made on or before their due dates. All such contributions have been fully deducted for income tax purposes and no such deduction has been challenged or disallowed by any Governmental Authority and no fact or event exists which could give rise to any such challenge or disallowance.

(ii) the fair market value of the assets of each funded Non-U.S. Benefit Plan, the liability of each insurer for any Non-U.S. Benefit Plan funded through insurance or the book reserve established for any Non-U.S. Benefit Plan, together with any accrued contributions, is sufficient to procure or provide for the benefits determined on any ongoing basis (actual or contingent) accrued to the Effective Date with respect to all current and former participants under such Non-U.S. Benefit Plan according to the actuarial assumptions and valuations most recently used to determine employer contributions to such Non-U.S. Benefit Plan, and no Transaction shall cause such assets or insurance obligations to be less than such benefit obligations; and

(iii) each Non-U.S. Benefit Plan required to be registered has been registered and has been maintained in good standing with applicable regulatory authorities. Each Non-U.S. Benefit Plan has been operated in full compliance with all applicable non-United States laws.

(i) The consummation of the Transactions will not, either alone or in combination with another event, (i) entitle any current or former employee, officer or director of the Company or any Subsidiary to severance pay, unemployment compensation or any other payment, or (ii) accelerate the time of payment or vesting, or increase the amount of compensation (in cash or otherwise) due any such employee, officer or director (except as required under Code Section 411(d)(3)). Without regard to any determination made under Section 280G(b)(4), no payment or benefit (whether under a Plan, a contract, agreement, arrangement or otherwise), which will or may be made by the Company, any Subsidiary or any of their respective Affiliates with respect to any current, former or retired employee, officer or director of the Company or any Subsidiary, will be characterized as an “excess parachute payment” within the meaning of Section 280G(b)(2).

(a) The Company agrees that neither it nor any Subsidiary nor any of the directors, officers or employees of it or any Subsidiary will, and that it will cause its and its Subsidiaries’ agents, advisors and other representatives (including, without limitation, any investment banker, attorney or accountant retained by it or any Subsidiary) not to, directly or indirectly, (i) solicit, initiate or encourage (including by way of furnishing nonpublic information), or take any other action to facilitate, any inquiries or the making of any proposal of offer (including, without limitation, any proposal or offer to its stockholders) that constitutes, or may reasonably be expected to lead to, any Competing Transaction, or (ii) enter into or maintain or continue discussions or negotiations with any Person or entity in furtherance of such inquiries or to obtain a proposal or offer for a Competing Transaction, or (iii) agree to, approve, endorse or recommend any Competing Transaction or enter into any letter of intent or other contract, agreement or commitment contemplating or otherwise relating to any Competing Transaction, or (iv) authorize or permit any of the officers, directors or employees of the Company or any of its Subsidiaries, or any investment banker, financial advisor, attorney, accountant or other representative retained by the Company or any of its Subsidiaries, to take any such action. The Company shall notify Purchaser as promptly as practicable (and in any event within one (1) Business Day after the Company attains knowledge thereof), orally and in writing, if any proposal or offer, or any inquiry or contact with any Person with respect thereto, regarding a Competing Transaction is made, specifying the material terms and conditions thereof and the identity of the party making such proposal or offer or inquiry or contact (including material amendments or proposed material amendments). The Company shall, and shall direct or cause its and its Subsidiaries’ directors, officers, employees, representatives and agents to, immediately cease and cause to be terminated any discussions or negotiations with any parties that may have been conducted heretofore with respect to a Competing Transaction. The Company shall not release any third party from, or

waive any provision of, any confidentiality or standstill agreement to which it is a party and the Company also agrees to promptly request each Person that has heretofore executed a confidentiality agreement in connection with its consideration of acquiring (whether by merger, acquisition of stock or assets or otherwise) the Company or any Subsidiary, if any, to return (or if permitted by the applicable confidentiality agreement, destroy) all confidential information heretofore furnished to such Person by or on behalf of the Company or any Subsidiary and, if requested by Purchaser and at Purchaser’s expenses, to enforce such Person’s obligation to do so. The Company shall not take any action to make the provisions of Section 203 of the DGCL inapplicable to any transaction other than the Transactions.

(b) Notwithstanding anything to the contrary in this Section 7.05, the Board may furnish information to, and enter into discussions with, a Person who has made an unsolicited, written, bona fide proposal or offer regarding a Competing Transaction, and the Board has (i) determined, in its good faith judgment (after having consulted with a financial advisor of nationally recognized reputation, which may include Xxxxxxxxx & Company, Inc. or an Affiliate or division thereof), that such proposal or offer constitutes a Superior Proposal, or in the absence of a Superior Proposal, determined, in its good faith judgment after consultation with independent legal counsel, that the furnishing of such information or entering into discussions is required to comply with its fiduciary obligations to the Company and its stockholders under applicable Law, (ii) provided written notice to Purchaser of its intent to furnish information or enter into discussions with such Person at least two Business Days prior to taking any such action, and (iii) obtained from such Person an executed confidentiality agreement on customary terms (it being understood that such confidentiality agreement and any related agreements shall not include any provision calling for any exclusive right to negotiate with such party or having the effect of prohibiting the Company from satisfying its obligations under this Agreement).

(c) Except as set forth in this Section 7.05(c), neither the Board nor any committee thereof shall withdraw or modify, or propose to withdraw or modify, in a manner adverse to Purchaser, the approval or recommendation by the Board or any such committee of any Transaction Agreement or any of the Transactions (a “Change in the Company Recommendation”) or approve or recommend, or cause or permit the Company to enter into any letter of intent, agreement or obligation with respect to, any Competing Transaction. Notwithstanding the foregoing, if the Board determines, in its good faith judgment prior to the Swap Closing and after consultation with independent legal counsel, that it is required to make a Change in the Company Recommendation to comply with its fiduciary obligations to the Company and its stockholders under applicable Law, the Board may make a Change in the Company Recommendation, but only (i) after providing written notice to Purchaser (a “Notice of Change in Recommendation”) advising Purchaser that the Board intends to effect a Change in the Company Recommendation and the manner in which it intends (or may intend) to do so, and (ii) if Purchaser does not, within five (5) Business Days of Purchaser’s receipt of the Notice of Change in Recommendation, make an offer that the Board determines, in its good faith judgment that it is no longer required by its fiduciary duties to make a Change in the Company Recommendation.

SECTION 7.06 Notification of Certain Matters. The Company shall give prompt notice to Purchaser, and Purchaser shall give prompt notice to the Company, of (a) the occurrence, or non-occurrence, of any event the occurrence, or non-occurrence, of which

reasonably could be expected to cause (i) any representation or warranty contained in this Agreement to be untrue or inaccurate in any material respect or (ii) any condition set forth in Annex D or Annex E not be satisfied, (b) any failure of the Company or Purchaser, as the case may be, to comply with or satisfy any covenant or agreement to be complied with or satisfied by it hereunder and (c) any other material development relating to the business, prospects, financial condition or results of operations of the Company and the Subsidiaries; provided, however, that the delivery of any notice pursuant to this Section 7.06 shall not limit or otherwise affect the remedies available hereunder to the party receiving such notice.

SECTION 7.07 Regulatory and Other Authorizations; Notices and Consents. (a) Each of Purchaser and the Company shall use its reasonable best efforts to obtain all authorizations, consents, orders and approvals of all Governmental Authorities and officials that may be or become necessary for its execution and delivery of, and the performance of its obligations pursuant to, the Transaction Agreements and will cooperate fully with the other party in promptly seeking to obtain all such authorizations, consents, orders and approvals. The Company shall, and shall cause the applicable Subsidiaries to (i) submit complete application documents for the Article 71 Waiver within two (2) Business Days after the Effective Date; (ii) supply as promptly as practicable to MEMR or other Government Authorities any additional information and documentary material that may be requested by MEMR or other Government Authorities; and (iii) at Purchaser’s request, provide or make available as promptly as practicable all information and documentary materials to enable Purchaser to make appropriate filings under the Anti-trust Laws in connection with the Transactions.

(b) The Company shall give promptly such notices to third parties and use its reasonable best efforts to obtain such third party consents and estoppel certificates as Purchaser may in its reasonable discretion deem necessary or desirable in connection with the Transactions.

(c) Purchaser shall cooperate and use its reasonable best efforts to assist the Company in giving such notices and obtaining such consents and estoppel certificates; provided, however, that Purchaser shall have no obligation to give any guarantee or other consideration of any nature in connection with any such notice, consent or estoppel certificate or to consent to any change in the terms of any agreement or arrangement which Purchaser in its sole discretion may deem adverse to the interests of Purchaser, the Company, any Subsidiary or their respective businesses.

(d) Company shall, and shall cause the Subsidiaries to, provide all such information, analysis, technical and other reports and documents and execute all such applications, documents and other things as may be required by the HKSE, any other Governmental Authority or Purchaser for the purposes of obtaining the Purchaser Shareholders Approval, the Exchange Approvals and any consent or waiver from the HKSE required under the HKSE Listing Rules and/or facilitating Purchaser to prepare and issue any announcement and circular in connection with the Transactions.

SECTION 7.08 Subsequent Financial Statements. The Company shall, if practicable, consult with Purchaser prior to making publicly available its financial results for any period after the Effective Date and prior to filing any report or document with the SEC after the

Effective Date, it being understood that Purchaser shall have no liability by reason of such consultation.

SECTION 7.09 Public Announcements. Purchaser and the Company agree that no public release or announcement concerning the Transactions shall be issued by either party without the prior consent of the other party (which consent shall not be unreasonably withheld), except as such release or announcement may be required by Law, or to the extent applicable, the AMEX rules or the HKSE Listing Rules, in which case the party required to make the release or announcement shall use its reasonable best efforts to allow the other party reasonable time to comment on such release or announcement in advance of such issuance.

SECTION 7.10 General Release from Initial Investors of Junior Preferred Stock. The Company shall use its reasonable best efforts to cause each Initial Investor of Junior Preferred Stock that is not a Key Junior Preferred Stockholder, on or prior to the Swap Closing, to execute and deliver to Purchaser, for the benefit of the Company and each Subsidiary, a general release and discharge, in a form attached hereto as Exhibit 7.10 (the “Release Letter”), waiving certain rights under the Additional Return Agreements.

SECTION 7.11 Existing Warrants. The Company shall use reasonable best efforts and take any and all steps necessary to obtain a waiver (the “Existing Warrants Waiver”) of the 20-day prior notice requirement triggered by the Transactions from each of the holders of the Existing Warrants except for any warrants issued pursuant to the Warrant Agreement, dated as of December 12, 2005 by and between the Company and The Bank of New York.

SECTION 7.12 Use of Proceeds. The proceeds (the “Proceeds”) received by the Company from the Transactions, including the First Tranche Price and the Second Tranche Price, shall be used solely to fund the capital requirements specified in the schedule attached hereto as Exhibit 7.12. The Proceeds shall be paid to the Company by the Escrow Agent in accordance with the terms of the Escrow Agreement and the Investor Rights Agreement.

SECTION 7.13 AMEX Listing. The Company shall promptly prepare and submit to the AMEX a listing application covering (a) the shares of Common Stock issuable upon the conversion of the New Preferred Stock pursuant to the terms and conditions set forth in the Certificate of Designations of Series B-1 Preferred Stock and Certificate of Designations of Series B-2 Preferred Stock; (b) the shares of Common Stock issuable under the Warrants; (c) the shares of Common Stock issuable upon the surrender of the 12% Senior Notes and the New Senior Notes then held by Purchaser or any of its Affiliates pursuant to Section 4.04(a); and (d) the shares of Common Stock issuable pursuant to Section 4.04(b) (the Common Stock referred to in clauses (a) through (d) collectively, the “New Common Shares”) and shall use its reasonable best efforts to obtain, prior to the Swap Closing, approval for the listing of such New Common Shares (the “AMEX Listing Approval”), and Purchaser shall cooperate with the Company with respect to such listing. The parties acknowledge that in order to obtain the AMEX Listing Approval or other Exchange Approvals necessary to consummate the Transactions, the parties may be required by AMEX to revise or amend the Transaction Agreements and, in particular, the Certificate of Designations of Series B-1 Preferred Stock and the Certificate of Designations of Series B-2 Preferred Stock, and the parties agree to use their reasonable best efforts to cooperate with AMEX to obtain the AMEX Listing Approval and other necessary Exchange Approvals,

including by effecting modifications to: (i) the conversion voting feature of the New Preferred Stock to offset a potential decline in the price of the Common Stock (provided that no such modification shall affect the conversion price of the New Preferred Stock); (ii) the board designation rights of the New Preferred Stock to correspond to Purchaser’s equity investment in the Company; and (iii) the board observer and director designee rights to be consistent with the director independence requirements for committees of the Board, to the extent a Purchaser director designee would not be considered independent under relevant AMEX rules. Notwithstanding the foregoing, if any revision or amendment required by AMEX, other than with respect to the matters set forth in (i) through (iii) above, materially and adversely impacts the rights or benefits to be received by Purchaser under the Transaction Agreements, as reasonably determined by Purchaser, then the AMEX Listing Approval shall be deemed not to have been satisfied for purposes of the condition set forth in subsection (g) of Annex D.

SECTION 7.14 Cancellation of Preferred Shares. The Company shall take all necessary actions to restore to the status of authorized but unissued shares of Preferred Stock without designation as to series by retiring all shares of Preferred Stock acquired from Purchaser pursuant to the Swap immediately following the Swap Closing.

SECTION 7.15 Registration Statement. The parties hereto shall use reasonable best efforts to structure the Transactions as transactions exempt from the registration requirements of the Securities Act; and the parties hereto acknowledge that it is currently contemplated that the Transactions will be structured as exempt from the registration requirements of the Securities Act. Subject to the foregoing, if required by U.S. securities Laws, the Company shall file with the SEC a registration statement on an appropriate registration statement form (the “Registration Statement”) that will cover the amendments of the terms of the Senior Preferred Stock and Junior Preferred Stock in connection with the Transactions and shall use its reasonable best efforts to cause such registration statement to become effective as soon as practicable and prior to the closing of the Offers. If required by the U.S. securities Laws and the Shares of Newly Issued Common Stock to be delivered to the Exercising Junior Preferred Stockholder(s) pursuant to Section 4.02 are not transferable without restriction pursuant to Rule 144 under the Securities Act at the time such shares are delivered, the Company shall file a shelf registration statement with the SEC with respect to the resale of such shares by such Exercising Junior Preferred Stockholder(s) within 30 days following the Swap Closing and shall use its reasonable best efforts to cause such registration statement to become effective as soon as practicable, in any event within 90 days, following the Swap Closing. Additionally, if Purchaser is required by U.S. securities Laws to file with the SEC a registration statement on an appropriate registration statement form that will cover the issuance of the Purchaser Convertible Bonds in connection with the Transactions, the Company shall cooperate with the reasonable requests of Purchaser in connection with such registration, which for the avoidance of doubt shall include cooperating in the manner set forth in Section 3.01(e) and (f) hereof to the extent applicable.

SECTION 7.16 Redemption of Remaining Preferred Stock. Immediately following the Swap Closing, the Company shall redeem, pursuant to the Amendment to the Certificate of Designations of the Senior Preferred Stock or the Amendment to the Certificate of Designations of the Junior Preferred Stock, as the case may be, all of the then-outstanding shares of Preferred Stock (the “Remaining Preferred Stock”), using funds provided by, or at the

direction of, Purchaser. The Company shall take all necessary actions to cancel all of the Remaining Preferred Stock immediately following such redemption.

SECTION 7.17 Withholding Rights. Purchaser shall be entitled to deduct and withhold from the consideration otherwise payable pursuant to this Agreement, including the Additional Returns, to any holder of Preferred Stock, any holder of the 12% Senior Notes or any Initial Investor of Junior Preferred Stock such amounts as it is required to deduct and withhold with respect to the making of such payment under the Internal Revenue Code of 1986, as amended (the “Code”) and the U.S. Treasury regulations promulgated thereunder, or any provision of state, local or non-United States Tax law. To the extent that amounts are so withheld by Purchaser, such withheld amounts shall be treated for all purposes of this Agreement as having been paid to the holder of Preferred Stock, any holder of the 12% Senior Notes or Initial Investor of Junior Preferred Stock, as the case may be, in respect of which such deduction and withholding was made by Purchaser.

SECTION 7.18 Alternative Transaction Structures. Purchaser shall have the right to propose alternative structures for the transactions contemplated in this Agreement and the Ancillary Documents in order to structure such transactions in a more tax-efficient manner. Purchaser’s direct and indirect economic and voting interests in any alternative structure shall be equivalent to its economic and voting interests in the structure contemplated in this Agreement. Such alternative structures may include, but are not limited to, (a) acquiring stock directly in the 12% Senior Notes Issuer and may involve transferring assets of the Company and the Subsidiaries, including stock of Subsidiaries, to the 12% Senior Notes Issuer; (b) investing directly in preferred stock and warrants of the 12% Senior Notes Issuer instead of preferred stock and warrants of the Company; and (c) transferring funds from the 12% Senior Notes Issuer to the Company to permit the Company to conduct the Tender Offer and the Exchange Offer directly. Any preferred stock or warrants of the 12% Senior Notes Issuer issued to Purchaser shall have rights and terms that are equivalent to the rights and terms of the First Tranche Shares and Second Tranche Shares and the Warrants, respectively. The Company agrees to accept and cooperate in implementing any such alternative structures as long as such structures do not have adverse consequences for the Company and do not materially delay the transactions contemplated in this Agreement and the Ancillary Documents.

SECTION 7.19 Employment Agreements. Notwithstanding anything to the contrary in this Article 7, the Company agrees that, prior to the Swap Closing, the Company (at the direction of Purchaser) will negotiate and use its reasonable best efforts to amend and restate the employment agreements and change in control agreements listed in Section 5.10(b) of the Disclosure Schedule to the reasonable satisfaction of Purchaser, which amended and restated agreements shall be effective immediately prior to the Swap Closing.

SECTION 7.20 Pre-Closing Funding. The Company shall be required to apply any funds received by the Company (a) through sales of surplus or obsolete equipment, (b) pursuant to oil sales or collection of trade receivables, or (c) through other means, towards the payment of the September 15, 2008 interest payments under the 12% Senior Notes or otherwise in accordance with Section 7.01 hereof. The Company shall notify Purchaser promptly (and in any event within one day) of any receipt by the Company of funds by any of the means set forth in (a) through (c) above (but with respect to (b) above, the Company’s obligation to provide

notice shall not arise with respect to any oil sales contracts with a term of less than three months) and Purchaser shall be entitled to direct, in its sole discretion, the allocation of such funds by the Company, including, without limitation, the use of such funds to pay interest under the 12% Senior Notes or to fund past due obligations, working capital requirements or otherwise.

SECTION 7.21 Cancellation of Notes. The Company shall take all necessary actions, or shall cause the 12% Senior Notes Issuer to take all necessary actions, to deliver to the Indenture Trustee for cancellation any and all 12% Senior Notes and New Senior Notes surrendered by Purchaser or any of its Affiliates pursuant to Section 4.04(a).

INDEMNIFICATION

SECTION 9.01 Survival of Representations and Warranties. (a) The representations and warranties of the Company contained in this Agreement shall survive the Swap Closing for eighteen (18) months following the Swap Closing; provided, however, that (i) the representations and warranties made pursuant to Sections 5.01, 5.02, 5.03, 5.04, 5.06,

5.26, 5.27 and 5.28 (the “Company Fundamental Representations”) shall survive indefinitely, (ii) the representations and warranties dealing with Tax matters (the “Tax Representations”) shall survive until 120 days after the expiration of the relevant statute of limitations for the Tax liabilities in question, and (iii) insofar as any claim is made by Purchaser for the breach of any representation or warranty of the Company contained herein relating to environmental matters (the “Environmental Representations”), such representations and warranties shall, for purposes of such claims by Purchaser, survive the Swap Closing until the tenth anniversary of the Swap Closing. Neither the period of survival nor the liability of the Company with respect to the Company’s representations and warranties shall be reduced by any investigation made at any time by or on behalf of Purchaser. If written notice of a claim has been given prior to the expiration of the applicable representations and warranties by Purchaser to the Company, then the relevant representations and warranties shall survive as to such claim, until such claim has been finally resolved.

(b) The representations and warranties of Purchaser contained in this Agreement shall survive the Swap Closing for eighteen (18) months following the Swap Closing; provided, however, that the representations and warranties made pursuant to Sections 6.01, 6.02 and 6.06 (the “Purchaser Fundamental Representations”; together with the Company Fundamental Representations, the “Fundamental Representations”) shall survive indefinitely. Neither the period of survival nor the liability of Purchaser with respect to Purchaser’s representations and warranties shall be reduced by any investigation made at any time by or on behalf of the Company. If written notice of a claim has been given prior to the expiration of the applicable representations and warranties by the Company to Purchaser, then the relevant representations and warranties shall survive as to such claim, until such claim has been finally resolved.

SECTION 9.02 Indemnification by the Company. Purchaser and its Affiliates, officers, directors, employees, agents, successors and assigns (each a “Purchaser Indemnified Party”) shall be indemnified and held harmless by the Company for and against any and all liabilities, losses, damages, claims, costs and expenses, interest, awards, judgments and penalties (including attorneys’ and consultants’ fees and expenses) suffered or incurred by them (including any Action brought or otherwise initiated by any of them) (hereinafter a “Loss”), arising out of or resulting from:

(a) the breach of any representation or warranty made by the Company in this Agreement (it being understood that such representations and warranties shall be interpreted without giving effect to any limitations or qualifications as to “materiality” (including the word “material”) or “Material Adverse Effect” set forth therein);

(b) the breach of any covenant or agreement by the Company contained in this Agreement;

(c) liabilities of the Company or any Subsidiary arising from or relating to any breach of any covenant or agreement or non-performance of any obligation by the Company or any Subsidiary with respect to (i) the Certificates of Designations of the Preferred Stock, (ii) the Indenture, or (iii) the Existing Warrants, to the extent such

breach or non-performance occurred prior to the Swap Closing and not due to any act or omission of Purchaser after the Effective Date; and

(d) liabilities of the Company or any Subsidiary arising from or relating to any of the Actions disclosed in Section 5.09 of the Disclosure Schedule (i) to the extent not reflected in the Company’s financial statements appearing in the most recent SEC Reports prior to the Effective Date or (ii) if so reflected, to the extent that any such liabilities so reflected are in excess of US$1,000,000, in the aggregate, of the reported amounts.

To the extent that the Company’s undertakings set forth in this Section 9.02 may be unenforceable, the Company shall contribute the maximum amount that it is permitted to contribute under applicable Law to the payment and satisfaction of all Losses incurred by the Purchaser Indemnified Parties.

SECTION 9.03 Indemnification by Purchaser. The Company and its successors and assigns (each a “Company Indemnified Party”) shall be indemnified and held harmless by Purchaser for and against any and all Losses, arising out of or resulting from:

(a) the breach of any representation or warranty made by Purchaser contained in this Agreement (it being understood that such representations and warranties shall be interpreted without giving effect to any limitations or qualifications as to “materiality” (including the word “material”) or “Material Adverse Effect” set forth therein); or

(b) the breach of any covenant or agreement by Purchaser contained in this Agreement.

To the extent that Purchaser’s undertakings set forth in this Section 9.03 may be unenforceable, Purchaser shall contribute the maximum amount that it is permitted to contribute under applicable Law to the payment and satisfaction of all Losses incurred by the Company Indemnified Parties.

SECTION 9.04 Limits on Indemnification. Notwithstanding anything to the contrary contained in this Agreement: (a) an Indemnifying Party shall not be liable for any claim for indemnification pursuant to Section 9.02(a) or 9.03(a), unless and until the aggregate amount of indemnifiable Losses which may be recovered from the Indemnifying Party equals or exceeds US$1,000,000 whereupon the Indemnified Party shall be entitled to indemnification for the full amount of such Losses; and (b) the maximum amount of indemnifiable Losses which may be recovered from an Indemnifying Party arising out of or resulting from the causes set forth in Section 9.02(a) or 9.03(a), as the case may be, shall be an amount equal to US$75,000,000. Notwithstanding the foregoing, the provisions of this Section 9.04 shall not apply with respect to the Fundamental Representations, Tax Representations and Environmental Representations, which shall not be subject to any limitations on indemnification.

SECTION 9.05 Notice of Loss; Third Party Claims. (a) An Indemnified Party shall give the Indemnifying Party notice of any matter that an Indemnified Party has determined has given or could give rise to a right of indemnification under this Agreement, within 60 days of such determination, stating the amount of the Loss, if known, and method of computation

thereof, and containing a reference to the provisions of this Agreement in respect of which such right of indemnification is claimed or arises.

(b) If an Indemnified Party shall receive notice of any Action, audit, demand or assessment (each, a “Third Party Claim”) against it or which may give rise to a claim for Loss under this Article IX, within 60 days of the receipt of such notice, the Indemnified Party shall give the Indemnifying Party notice of such Third Party Claim; provided, however, that the failure to provide such notice shall not release the Indemnifying Party from any of its obligations under this Article IX except to the extent that the Indemnifying Party is materially prejudiced by such failure and shall not relieve the Indemnifying Party from any other obligation or liability that it may have to any Indemnified Party otherwise than under this Article IX. The Indemnifying Party shall be entitled to assume and control the defense of such Third Party Claim at its expense and through counsel of its choice if it gives notice of its intention to do so to the Indemnified Party within five days of the receipt of notice from the Indemnified Party of such Third Party Claim; provided, however, that if there exists or is reasonably likely to exist a conflict of interest that would make it inappropriate in the judgment of the Indemnified Party in its sole and absolute discretion for the same counsel to represent both the Indemnified Party and the Indemnifying Party, then the Indemnified Party shall be entitled to retain its own counsel in each jurisdiction for which the Indemnified Party determines counsel is required, at the expense of the Indemnifying Party. In the event that the Indemnifying Party exercises the right to undertake any such defense against any such Third Party Claim as provided above, the Indemnified Party shall cooperate with the Indemnifying Party in such defense and make available to the Indemnifying Party, at the Indemnifying Party’s expense, all witnesses, pertinent records, materials and information in the Indemnified Party’s possession or under the Indemnified Party’s control relating thereto as is reasonably required by the Indemnifying Party. Similarly, in the event the Indemnified Party is, directly or indirectly, conducting the defense against any such Third Party Claim, the Indemnifying Party shall cooperate with the Indemnified Party in such defense and make available to the Indemnified Party, at the Indemnifying Party’s expense, all such witnesses, records, materials and information in the Indemnifying Party’s possession or under the Indemnifying Party’s control relating thereto as is reasonably required by the Indemnified Party. No such Third Party Claim may be settled by the Indemnified Party without the prior written consent of the Indemnifying Party, which may not be unreasonably withheld.

SECTION 9.06 Payment in Common Stock. In the event any Losses are payable by the Company to any Purchaser Indemnified Party hereunder, upon written notice to the Company, such Purchaser Indemnified Party shall be entitled to receive, in lieu of payment in cash, payment of such Losses in the form of shares of Common Stock. The number of shares of Common Stock to be issued to such Purchaser Indemnified Party hereunder shall be determined by dividing the total amount of the applicable indemnifiable Losses by the average of the Volume Weighted Average Stock Price over the 30 consecutive trading days immediately prior to the Determination Date. If the Volume Weighted Average Price cannot be calculated due to the absence of a trading market in the Common Stock, the number of shares issuable shall be determined by dividing the total amount of the applicable indemnifiable Losses by the Fair Market Value of the Common Stock on the Determination Date.

SECTION 10.03 Fees and Expenses. (a) In the event that

(i) this Agreement is terminated (A) pursuant to Section 10.01(c)(iii) or (B) pursuant to Section 10.01(c)(i) or 10.01(c)(ii), to the extent that the termination of this Agreement, any of the Senior Preferred Stock Purchase Agreements or the Junior Preferred Stock Purchase Agreement is caused by the Company due to the failure of the Company to perform, in any material respect, any of its covenants or agreements contained in this Agreement or the material breach by the Company of any of its representations or warranties contained in this Agreement or that the failure to commence, the termination or the failure to accept any Remaining Share of the Preferred Stock or 12% Senior Notes for payment, as set forth in Section 10.01(c)(ii), shall relate to the failure of the Company to perform, in any material respect, any of its covenants or agreements contained in this Agreement or the material breach by the Company of any of its representations or warranties contained in this Agreement; or

(ii) the Company enters into an agreement with respect to a Competing Transaction, or a Competing Transaction is consummated, in each case within 18 months after the termination of this Agreement (A) as a result of a material or intentional breach by the Company of Section 7.05 or (B) the Company was involved in discussions or negotiations with respect to such Competing Transaction prior to the termination of this Agreement, and the Company shall not theretofore have been required to pay the Fee to Purchaser pursuant to Section 10.03(a)(i);

then, in any such event, the Company shall pay Purchaser promptly (but in no event later than one Business Day after the first of such events shall have occurred) a fee equal to US$10,000,000 (the “Fee”), which amount shall be payable in immediately available funds.

(b) If this Agreement is terminated for any reason other than a termination (i) solely as a result of the failure of the parties hereto to obtain (A) the clearance or approval under Exon-Xxxxxx Provisions or the applicable Anti-trust Laws, (B) the AMEX Listing Approval or other Exchange Approvals, (C) the Article 71 Waiver or (D) the Purchaser Shareholders Approval or (ii) solely as a result of the non-satisfaction of the Minimum Condition or the Exchange Offer Minimum Condition, and Purchaser is not in material breach of its material covenants and agreements contained in this Agreement or its representations and warranties contained in this Agreement, the Company shall, whether or not any payment is made pursuant to Section 10.03(a), reimburse Purchaser (not later than five Business Days after submission of statements therefor) for all out-of-pocket expenses and fees up to US$3,000,000 in the aggregate (including, without limitation, fees and expenses payable to all banks, investment banking firms, other financial institutions, and other Persons and their respective agents and counsel, for arranging, committing to provide or providing any financing for the Transactions or structuring the Transactions, and all fees of counsel, accountants, experts and consultants to Purchaser, and all printing and advertising expenses and filing fees) actually incurred or accrued by either of them or on their behalf in connection with the Transactions, including, without limitation, the financing thereof, and actually incurred or accrued by banks, investment banking firms, other financial institutions and other Persons, and for which Purchaser is liable in connection with the negotiation, preparation, execution and performance of this Agreement, the structuring and financing of the Transactions and any financing commitments or agreements relating thereto (all the foregoing being referred to herein collectively as the “Expenses”).

(c) Except as set forth in this Section 10.03, all costs and expenses incurred in connection with this Agreement and the Transactions shall be paid by the party incurring such expenses, whether or not any Transaction is consummated.

(d) In the event that the Company shall fail to pay the Fee or any Expenses when due, unless such Fees and Expenses are being contested in good faith, the term “Expenses” shall be deemed to include the costs and expenses actually incurred or accrued by Purchaser (including, without limitation, fees and expenses of counsel) in connection with the collection under and enforcement of this Section 10.03, together with interest on such unpaid Fee and Expenses, commencing on the date that the Fee or such Expenses became due, at a rate equal to the rate of interest publicly announced by Citibank, N.A., from time to time, in the City of New York, as such bank’s Base Rate.

(e) In the event any Fee or Expenses, including any applicable interest accrued thereon pursuant to Section 10.03(d) (collectively, the “Unpaid Fees”), are payable by the Company to Purchaser hereunder, upon written notice to the Company, Purchaser shall be entitled to receive, in lieu of payment in cash, payment of such Unpaid Fees in the form of shares of Common Stock. The number of shares of Common Stock to be issued to Purchaser hereunder shall be determined by dividing the total amount of the applicable Unpaid Fees by the average of the Volume Weighted Average Stock Price over the 30 consecutive trading days immediately prior to the Determination Date. If the Volume Weighted Average Price can not be calculated

due to the absence of a trading market in the Common Stock, the number of shares issuable shall be determined by dividing the total amount of the applicable indemnifiable Losses by the Fair Market Value of the Common Stock on the Determination Date.

SECTION 10.04 Amendment. This Agreement may be amended by the parties hereto by action taken by or on behalf of their respective Boards of Directors at any time prior to the Swap Closing. This Agreement may not be amended except by an instrument in writing signed by each of the parties hereto.

SECTION 10.05 Waiver. At any time prior to the Swap Closing, any party hereto may (a) extend the time for the performance of any obligation or other act of any other party hereto, (b) waive any inaccuracy in the representations and warranties of any other party contained herein or in any document delivered pursuant hereto and (c) waive compliance with any agreement of any other party or any condition to its own obligations contained herein. Any such extension or waiver shall be valid if set forth in an instrument in writing signed by the party or parties to be bound thereby.

SECTION 11.02 Severability. If any term or other provision of this Agreement is invalid, illegal or incapable of being enforced by any rule of law, or public policy, all other conditions and provisions of this Agreement shall nevertheless remain in full force and effect so long as the economic or legal substance of the Transactions is not affected in any manner adverse to any party. Upon such determination that any term or other provision is invalid, illegal or incapable of being enforced, the parties hereto shall negotiate in good faith to modify this Agreement so as to effect the original intent of the parties as closely as possible in a mutually acceptable manner in order that the Transactions be consummated as originally contemplated to the fullest extent possible.

SECTION 11.03 Entire Agreement; Assignment. This Agreement and the Ancillary Documents constitute the entire agreement among the parties with respect to the subject matter hereof and supersede all prior agreements and undertakings, both written and oral, among the parties, or any of them, with respect to the subject matter hereof, including the Prior Agreements. This Agreement and the Ancillary Documents shall not be assigned (whether pursuant to a merger, by operation of law or otherwise), except that Purchaser may assign all or any of their rights and obligations hereunder to any Affiliate of Purchaser, provided that no such assignment shall relieve the assigning party of its obligations hereunder if such assignee does not perform such obligations. For the avoidance of doubt, Purchaser shall be entitled to conduct the Transactions through a wholly owned subsidiary of Purchaser; provided, however, that Purchaser shall guarantee the obligations of such subsidiary in connection therewith.

SECTION 11.04 Parties in Interest and Assignment. This Agreement shall be binding upon and inure solely to the benefit of each party hereto, and nothing in this Agreement, express or implied, is intended to or shall confer upon any other Person any right, benefit or remedy of any nature whatsoever under or by reason of this Agreement; provided, however, that Purchaser may assign all or any of its rights and obligations hereunder to any of its Affiliates, provided that no such assignment shall relieve Purchaser of its obligations hereunder if such assignee does not perform such obligations.

SECTION 11.05 Specific Performance. The parties hereto agree that irreparable damage would occur in the event any provision of this Agreement were not performed in accordance with the terms hereof and that the parties shall be entitled to specific performance of the terms hereof, in addition to any other remedy at law or equity.

SECTION 11.06 Governing Law. This Agreement shall be governed by, and construed in accordance with, the laws of the State of New York applicable to contracts executed in and to be performed in that State (other than those provisions set forth herein that are required to be governed by the DGCL). All actions and proceedings arising out of or relating to this Agreement shall be heard and determined exclusively in any New York state or federal court sitting in The City of New York. The parties hereto hereby (a) submit to the exclusive jurisdiction of any state or federal court sitting in The City of New York for the purpose of any action or proceeding arising out of or relating to this Agreement brought by any party hereto, and (b) irrevocably waive, and agree not to assert by way of motion, defense, or otherwise, in any such action or proceeding, any claim that it is not subject personally to the jurisdiction of the above-named courts, that its property is exempt or immune from attachment or execution, that the action or proceeding is brought in an inconvenient forum, that the venue of the action or proceeding is improper, or that this Agreement or the Transactions may not be enforced in or by any of the above-named courts. Purchaser hereby irrevocably appoints CT Corporation to receive service of process on its behalf as its respective authorized agent for service of process in any state or federal court sitting in The City of New York. If for any reason such agent shall cease to be such agent for service of process, Purchaser shall forthwith appoint a new agent for service of process and deliver to the Company a copy of the new agent’s acceptance of appointment within 30 days. Nothing in this Agreement shall affect the right to serve process in any other manner permitted by law.

SECTION 11.07 Headings. The descriptive headings contained in this Agreement are included for convenience of reference only and shall not affect in any way the meaning or interpretation of this Agreement.

SECTION 11.08 Counterparts. This Agreement may be executed and delivered (including by facsimile transmission) in one or more counterparts, and by the different parties hereto in separate counterparts, each of which when executed shall be deemed to be an original but all of which taken together shall constitute one and the same agreement.

SECTION 11.09 Waiver of Jury Trial. Each of the parties hereto hereby waives to the fullest extent permitted by applicable law any right it may have to a trial by jury with respect to any litigation directly or indirectly arising out of, under or in connection with this Agreement or the Transactions. Each of the parties hereto (a) certifies that no representative, agent or attorney of any other party has represented, expressly or otherwise, that such other party would not, in the event of litigation, seek to enforce that foregoing waiver and (b) acknowledges that it and the other hereto have been induced to enter into this Agreement and the Transactions, as applicable, by, among other things, the mutual waivers and certifications in this Section 11.09.

SECTION 11.10 Effective Date. The Company and Purchaser hereby agree that this Agreement shall be effective as of the Effective Date, including, without limitation, with respect to the representations, warranties and covenants of the Company and Purchaser set forth herein.

IN WITNESS WHEREOF, Purchaser and the Company have caused this Agreement to be executed as of September 22, 2008 by their respective officers thereunto duly authorized.
