Except as set forth in the Fund Partnership Agreement, the LLC Agreement and the Third Point Agreements, no Person has demand or other rights to cause any Transaction Party to file any registration statement under the Securities Act relating to any securities of any Transaction Party or any right to participate in any such registration statement, including piggyback registration rights.

SECTION 3.15 Books and Records. The books of account, ledgers, order books, records and documents of each Transaction Party accurately and completely reflect in accordance with usual and customary prudent business practices all material information relating to such Person’s business, the location and collection of such Person’s assets and the nature of all transactions giving rise to such Person’s obligations and accounts receivable.

SECTION 3.16 Taxes. Each Transaction Party has filed or caused to be filed all federal, state and other material tax returns, reports and statements (collectively, “Tax Returns”) that are required to be filed by any either or any of their respective Tax Affiliates with the appropriate

Governmental Authorities in all jurisdictions in which such Tax Returns are required to be filed; all such Tax Returns are true and correct in all material respects and correctly reflect the facts regarding the income, business, assets, operations, activities, status or other matters of such Person and any other information required to be shown thereon; each Transaction Party has paid, prior to the date on which any fine, penalty, interest, late charge or loss may be added thereto for non-payment thereof, all taxes shown to be due and payable on said returns or on any assessments made against it or any of its property and all other taxes, fees or other charges imposed on it or any of its property by or otherwise due and payable to any Governmental Authority (other than any the amount or validity of which are currently being contested in good faith by appropriate proceedings and with respect to which reserves in conformity with GAAP have been provided on the books of such Person); no tax Lien has been filed against the property of any Transaction Party; and, to the best knowledge of the Company, no claim is being asserted, with respect to any such tax, fee or other charge. No Tax Return is under audit or examination by any Governmental Authority and no notice of such an audit or examination or any assertion of any claim for taxes has been given or made by any Governmental Authority. Proper and accurate amounts have been withheld by each Transaction Party and each of their respective Tax Affiliates from their respective employees for all periods in full and complete compliance with the tax, social security and unemployment withholding provisions of applicable requirements of Law and such withholdings have been timely paid to the respective Governmental Authorities. There are no tax sharing agreements or similar arrangements with respect to or involving any entity in any Transaction Party. From its inception and immediately after the Closing, the Company has been and will be classified as a partnership for federal income tax purposes.

SECTION 3.17 ERISA. No Reportable Event nor an “accumulated funding deficiency” (within the meaning of Section 412 of the Code or Section 302 of ERISA) has occurred with respect to any Transaction Party during the five-year period prior to the date on which this representation is made or deemed made with respect to any Benefit Plan, and each Benefit Plan has complied in all material respects with the applicable provisions of ERISA and the Code. No termination of a Single Employer Plan of a Transaction Party has occurred, and no Lien in favor of the PBGC or a Benefit Plan has arisen, during such period. The present value of all accrued benefits under each Single Employer Plan (based on those assumptions used to fund such Benefit Plans) of the Company did not, as of the last annual valuation date prior to the date on which this representation is made or deemed made, exceed the value of the assets of such Benefit Plan allocable to such accrued benefits by a material amount. Neither the Transaction Parties nor any Commonly Controlled Entity has had a complete or partial withdrawal from any Multiemployer Plan that has resulted or could reasonably be expected to result in a material liability under ERISA, and neither the Transaction Parties nor any Commonly Controlled Entity would become subject to any material liability under ERISA if such Transaction Party or any such Commonly Controlled Entity were to withdraw completely from all Multiemployer Plans as of the valuation date most closely preceding the date on which this representation is made or deemed made. No such Multiemployer Plan is in reorganization or insolvent.

SECTION 3.18 Ownership of Property. Each Transaction Party has Defensible Title to all of its properties which constitute, for applicable state law purposes, “real” or “immovable” property, or an interest therein, and good and indefeasible title to all of the properties which constitute, for applicable state law purposes, “personal” or “movable” property.

SECTION 3.19 Transactions with Affiliates. Except as set forth on the Schedule 3.19 or as contemplated by the Transaction Documents, no Transaction Party is a party to any agreement

with any of its respective partners, directors, officers, trustees or members or any Affiliate or family member of any of the foregoing under which it: (i) leases any real or personal property (either to or from such Person), (ii) licenses technology (either to or from such Person), (iii) is obligated to purchase any tangible or intangible asset from or sell such asset to such Person, (iv) purchases products or services from such Person or (v) has borrowed money from or lent money to such Person. No Transaction Party employs as an employee or engages as a consultant any family member of any of such Person’s managers, directors, officers, trustees or partners. To the best knowledge of the Company, there exist no agreements among the partners or members, as the case may be, of any Transaction Party to act in concert with respect to their voting or holding of partnership or membership interests, as applicable.

SECTION 3.20 Disclosure. The Company has disclosed or made available to the Investors all facts material to the Company’s business, operations, assets, liabilities, prospects, properties, condition (financial or otherwise) and results of operations. None of this Agreement, any Transaction Document, any Schedule or Exhibit to any such agreement, or any other statements, documents or certificates made or delivered in connection herewith or therewith contains any untrue statement of a material fact or omits to state a material fact necessary to make the statements contained herein and therein not misleading in light of the circumstances under which such statements were made. There is no fact that the Company has not disclosed to the Investors and of which the Company is aware which has resulted in, or, insofar as the Company can reasonably anticipate, could be reasonably expected to result in, a Material Adverse Change. The financial projections and other estimates provided to the Investors were prepared by the Company and on assumptions of fact and opinion as to future events which the Company, at the date of the issuance of such financial projections and other estimates, believed to be reasonable and which the Company currently believes are reasonable. As of the date hereof, no facts have come to the Company’s attention that would, in its opinion, require the Company to revise or amplify the assumptions underlying such projections and other estimates or the conclusions derived therefrom.

ARTICLE VI.

SECTION 6.02 Covenants Pending Closing. Pending the Closing, the Company will not, and will not permit any other Transaction Party to, without the Institutional Investors’ prior written consent, take any action which would result in any of the representations or warranties contained in this Agreement not being true at and as of the time immediately after such action, or in any of the covenants contained in this Agreement becoming incapable of performance.

SECTION 6.03 Fund Securities Filings. The Company shall cause the Fund, no later than 15 days following the execution of this Agreement, (i) to file a post-effective amendment to the Registration Statement in a form required by the Securities Act and otherwise acceptable to the Institutional Investors, together with any exhibits required to be filed therewith (the “Amended Registration Statement”); (ii) to file an amendment to the Schedule TO in a form required by the Exchange Act and otherwise acceptable to the Institutional Investors, together with any exhibits required to be filed therewith.

SECTION 6.04 Consents and Approvals. From and after the date hereof, the Company shall use its best efforts to obtain as promptly as practicable any consent or approval of any Person, including, without limitation, any regulatory authority, Governmental Entity required in connection

with the transactions contemplated by this Agreement, any other Transaction Document or the consummation of the Transactions.

SECTION 6.09 Further Assurances. The Company and the each of the Investors covenants and agrees to cooperate and use all commercially reasonable efforts to take, or cause to be taken, all action and to do, or cause to be done, all things necessary, proper or advisable to consummate and make effective the transactions contemplated by this Agreement and the other Transaction Documents, including cooperating fully with the other parties to obtain all approvals that may be necessary or which may be reasonably requested by the Company or the Investors to consummate the transactions contemplated by this Agreement and the other Transaction Documents. In case at any time after the date hereof any commercially reasonable further action is reasonably necessary or desirable to carry out the purposes of this Agreement, the parties hereto shall take all such reasonably necessary action. The Institutional Investors shall not be required to expend material funds in connection with their obligations under this Section 6.09.

SECTION 6.10 Public Disclosures. Any public announcements regarding the terms of this Agreement or the other Transaction Documents or the transactions contemplated hereby and thereby, or the financial performance of the Company shall be made only with the consent of the Institutional Investors, which consent shall not be unreasonably withheld or delayed. To the extent an Institutional Investor is required to issue a public announcement by applicable law or stock exchange regulations, such Institutional Investor shall allow the other Institutional Investor reasonable time to comment on such release or statement in advance of its issuance.

SECTION 6.1l Indemnity.

(a) The Company agrees to indemnify, defend and hold harmless the Investors (and their partners (and each officer and director thereof), directors, managers, officers, members, stockholders, employees, Affiliates, agents and permitted assigns) (each an “Indemnified Party”) from and against any and all losses, claims, liabilities, damages, deficiencies, costs or expenses (including interest, penalties, reasonable attorneys’ and experts’ fees, disbursements and related charges and any costs or expenses that an indemnified party incurs to enforce its right to indemnification or in connection with investigating, defending or preparing to defend any action, proceeding or claim) of any nature whatsoever, whether actual or consequential, at the time they are incurred (collectively, “Damages”), asserted against, imposed upon, or incurred by any Indemnified Party, directly or indirectly, by reason of any inaccuracy in or breach of any representations, warranties, covenants or agreements of the Company contained in this Agreement or any other Transaction Document or in any certificate, instrument or document delivered hereunder or thereunder.

(b) Promptly after receipt by the Indemnified Party under this Section 6.11 of notice of any claim or the commencement of any action, or after an Indemnified Party otherwise becoming aware of facts or circumstances giving rise to any Damages, such Indemnified Party shall, if a claim in respect thereof is to be made against an indemnifying party under such section, give written notice to the indemnifying party of the commencement thereof, but the failure to so notify the indemnifying party shall not relieve it of any liability that it may have to any Indemnified Party except to the extent the indemnifying party reasonably demonstrates that the defense of, or the limitation of liability in connection with, such action is materially prejudiced thereby. In case any such action shall be brought against an Indemnified Party and the Indemnified Party shall give written notice to the indemnifying party of the commencement thereof, the indemnifying party shall be entitled to participate therein and, to the extent that it may elect, to assume the defense

thereof with counsel reasonably satisfactory to such Indemnified Party. If the indemnifying party elects to assume the defense of such action, the Indemnified Party shall have the right to employ separate counsel at its own expense and to participate in the defense thereof. If the indemnifying party elects not to assume (or fails to assume) the defense of such action, the Indemnified Party shall be entitled to assume the defense of such action with counsel of its own choice, at the expense of the indemnifying party. In such event, upon written notice by the Indemnified Party requesting advance payment of a stated amount for its reasonable defense costs and expenses, the indemnifying party shall advance payment for such reasonable defense costs and expenses (the “Advance Indemnification Payment”) to the Indemnified Party. In the event that the Indemnified Party’s actual defense costs and expenses exceed the amount of the Advance Indemnification Payment, then upon written request by the Indemnified Party, the indemnifying party shall reimburse the Indemnified Party for such difference; in the event that the Advance Indemnification Payment exceeds the Indemnified Party’s actual costs and expenses, the Indemnified Party shall promptly remit payment of such difference to the indemnifying party. If the action is asserted against both the indemnifying party and the Indemnified Party and, in the reasonable judgment of the Indemnified Party, there is a conflict of interests that renders it inappropriate for the same counsel to represent both the indemnifying party and the Indemnified Party or any Affiliate or associate thereof, the indemnifying party shall be responsible for paying for separate counsel retained by the Indemnified Party for the Indemnified Party to the extent the Indemnified Party would otherwise be entitled to indemnification under this section; provided however, that if there is more than one Indemnified Party, the indemnifying party shall not be responsible for paying for more than one separate firm of attorneys to represent the Indemnified Parties, regardless of the number of Indemnified Parties. If the indemnifying party elects to assume the defense of such action, (i) no compromise or settlement thereof may be affected by the indemnifying party without the Indemnified Party’s written consent (which shall not be unreasonably withheld) unless the sole relief provided is monetary damages that are paid in full by the indemnifying party and (ii) the Indemnified Party shall have no liability or obligations with respect to any compromise or settlement thereof affected without its written consent (which shall not be unreasonably withheld).

(c) The provisions of this Section 6.11 shall not limit or impair any right or remedy arising from breach of this Agreement or any Transaction Document. In addition to any other remedy provided by law, injunctive relief may be obtained to enjoin the breach, or threatened breach, of any provision of this Agreement or any Transaction Document and each party hereto shall be entitled to specific performance by the others of their obligations hereunder and thereunder. All remedies, either under this Agreement or any Transaction Document, by law or as may otherwise be afforded to the Investors or the Company, as the case may be, shall be cumulative.

SECTION 6.12 Expenses. Each Investor hereby agrees to bear its proportionate share (determined by reference to its Sharing Ratio) of the reasonable costs, expenses and disbursements incurred by the Company, any Investor and/or any of their respective Affiliates at any time on or after March 1, 2006 in connection with the negotiation, preparation and execution of this Agreement and the other Transaction Documents, subject to a maximum amount equal to its proportionate share of $1,000,000 (the “Transaction Expenses”). Each Investor shall be responsible for its proportionate share of the Transaction Expenses regardless of whether the Closing shall occur. At any time prior to the Closing Date, upon receipt of a written request from

the Company accompanied by supporting documentation reasonably acceptable to the Institutional Investors, each Investor shall promptly, and in any event within 10 days, pay all or such requested portion of its proportionate share of the Transactions Expenses incurred as of the date of such request. Following the Closing, the Company shall promptly, and in any event within 10 days, pay or reimburse each Investor or any of their respective Affiliates for the Transaction Expenses paid by it pursuant to this Section 6.12 and for all other out-of-pocket expenses it has incurred in connection with its consideration of an investment in the Company, due diligence of the Company, the negotiation, preparation and execution of this Agreement and the other Transaction Documents and the consummation of the transactions hereunder and thereunder.

ARTICLE VII.
MISCELLANEOUS

SECTION 7.01 Survival of Agreements. All covenants, agreements, representations and warranties made in this Agreement or any of the other Transaction Documents or any certificate or instrument delivered to the Investors pursuant to or in connection with this Agreement or any of the other Transaction Documents shall survive the execution and delivery of this Agreement and all of the other Transaction Documents, the issuance, sale and delivery of the Membership Interests, and all statements contained in any certificate or other instrument delivered by the Company hereunder or thereunder or in connection herewith or therewith shall be deemed to constitute representations and warranties made by the Company.

No party may assign any rights or obligations under this Agreement except (i) that any Institutional Investor may assign and/or delegate any portion or all of its rights and obligations under this Agreement to any affiliated fund and (ii) with the express consent of the Institutional Investors (a “Permitted Assignment”). Upon any Permitted Assignment, the references in this Agreement to an Investor shall also apply to any such assignee and all representations, warranties, covenants and agreements contained in this Agreement or any other Transaction Document by or on behalf of the parties hereto shall bind and inure to the benefit of such assignees whether so expressed or not. Nothing in this Agreement shall create or be deemed to create any third-party beneficiary rights in any Person not a party to this Agreement except as provided herein. Whether or not any express assignment has been made, the provisions of this Agreement which are for the benefit of any Investor as a purchaser or holder of Membership Interests are also for the benefit of and enforceable by any subsequent holder of such Membership Interests who acquires at least 50% of the Membership Interests of an Investor to the same extent they would have been enforceable by such Investor.

SECTION 7.03 Notices. Any notice, request, demand or other communication required or permitted to be given to a party hereto pursuant to the provisions of this Agreement will be in writing and will be effective and deemed given under this Agreement on the earliest of: (a) the date of personal delivery, (b) the date of transmission by facsimile, with confirmed transmission and receipt, (c) one day after deposit with a nationally-recognized courier or overnight service such as Federal Express, or (d) five days after mailing via certified mail, return receipt requested.

(a) submits for itself and its property in any legal action or proceeding relating to this Agreement and the other Transaction Documents to which it is a party (whether for claims sounding in contract or in tort), or for recognition and enforcement of any judgment in respect thereof, to the non exclusive general jurisdiction of the courts of the State of New York, the courts of the United States of America for the Southern District of New York, and appellate courts from any thereof;

(b) consents that any such action or proceeding may be brought in such courts and waives any objection that it may now or hereafter have to the venue of any such action or proceeding in any such court or that such action or proceeding was brought in an inconvenient court and agrees not to plead or claim the same;

(c) agrees that service of process in any such action or proceeding may be effected by mailing a copy thereof by registered or certified mail (or any substantially similar form of mail), postage prepaid, to the address as set forth in Section 7.03 or at such other address of which the parties hereto shall have been notified pursuant thereto;

(d) agrees that nothing herein shall affect the right to effect service of process in any other manner permitted by law or shall limit the right to sue in any other jurisdiction; and

(e) WAIVES, TO THE MAXIMUM EXTENT NOT PROHIBITED BY LAW, ANY RIGHT IT MAY HAVE TO CLAIM OR RECOVER IN ANY LEGAL ACTION OR PROCEEDING REFERRED TO IN THIS SECTION ANY SPECIAL, EXEMPLARY, PUNITIVE OR CONSEQUENTIAL DAMAGES.

SECTION 7.06 WAIVER OF JURY TRIAL. THE COMPANY AND EACH OF THE INVESTORS HEREBY KNOWINGLY, VOLUNTARILY AND INTENTIONALLY, IRREVOCABLY AND UNCONDITIONALLY WAIVE TRIAL BY JURY IN ANY LEGAL ACTION OR PROCEEDING RELATING TO THIS AGREEMENT OR ANY OTHER TRANSACTION DOCUMENT AND FOR ANY COUNTERCLAIM THEREIN (IN EACH CASE, WHETHER FOR CLAIMS SOUNDING IN CONTRACT OR IN TORT).

SECTION 7.07 Entire Agreement. This Agreement and the other Transaction Documents, together with the certificates, documents, instruments and writings that are delivered

pursuant thereto, constitute the entire agreement and understanding of the parties hereto in respect of the subject matter hereof or the transactions contemplated hereby and supersedes all prior understandings, agreements, or representations by or among such parties, written or oral, to the extent they relate in any way to the subject matter hereof or the transactions contemplated hereby.

SECTION 7.08 Counterparts. This Agreement may be executed in two or more counterparts, each of which will be deemed an original but all of which together will constitute one and the same instrument.

SECTION 7.09 Amendments and Waivers. This Agreement may not be amended or modified, and no provisions hereof may be waived, without the written consent of each of the Company, Lehman and Ospraie. No action taken pursuant to this Agreement, including any investigation by or on behalf of any party hereto, shall be deemed to constitute a waiver by the party taking such action of compliance with any representation, warranty, covenant or agreement contained herein. The waiver by any party hereto of a breach of any provision of this Agreement shall not operate or be construed as a further or continuing waiver of such breach or as a waiver of any other or subsequent breach. No failure on the part of any party hereto to exercise, and no delay in exercising, any right, power or remedy hereunder shall operate as a waiver thereof, nor shall any single or partial exercise of such right, power or remedy by such party preclude any other or further exercise thereof or the exercise of any other right, power or remedy. All remedies hereunder are cumulative and are not exclusive of any other remedies provided by Law.

SECTION 7.10 Severability. The provisions of this Agreement will be deemed severable and the invalidity or unenforceability of any provision hereof will not affect the validity or enforceability of the other provisions hereof; provided that if any provision of this Agreement, as applied to any party hereto or to any circumstance, is adjudged by a court, governmental body, arbitrator or mediator not to be enforceable in accordance with its terms, the parties hereto agree that the court, governmental body, arbitrator or mediator making such determination will have the power to modify the provision in a manner consistent with its objectives such that it is enforceable, and/or to delete specific words or phrases, and in its reduced form, such provision will then be enforceable and will be enforced.

SECTION 7.11 Titles and Subtitles. The article and section headings contained in this Agreement are inserted for convenience only and will not affect in any way the meaning or interpretation of this Agreement.

SECTION 7.12 No Reliance. Each of the Investors acknowledges that they are not relying upon any Person, other than the Company and its officers and directors (acting in their capacity as representatives of the Company), in deciding to invest and in making its investment in the Company.

SECTION 7.13 Construction. The parties hereto have jointly participated in the negotiation and drafting of this Agreement. If an ambiguity or question of intent or interpretation arises, this Agreement will be construed as if drafted jointly by the parties hereto and no presumption or burden of proof will arise favoring or disfavoring any party hereto because of the authorship of any provision of this Agreement. Any reference to any federal, state, local or foreign law will also be deemed to refer to such law as amended and all rules and regulations promulgated thereunder, unless the context otherwise requires. The words “including,” “includes” and “include” shall be deemed to be followed by “without limitation.” Pronouns in masculine, feminine and

neuter genders will be construed to include any other gender, and words in the singular form will be construed to include the plural and vice versa, unless the context otherwise requires. The words “this Agreement,” herein, “hereof,” “hereby,” “hereunder” and words of similar import refer to this Agreement as a whole and not to any particular subdivision unless expressly so limited. The parties hereto intend that each representation, warranty and covenant contained herein will have independent significance. If any party hereto has breached any representation, warranty or covenant contained herein in any respect, the fact that there exists another representation, warranty or covenant relating to the same subject matter (regardless of the relative levels of specificity) which such party hereto has breached, will not detract from or mitigate the fact that such party hereto is in breach of the first representation, warranty or covenant.

SECTION 7.14 Remedies. The parties hereto shall have all remedies for breach of this Agreement available to them as provided by law or equity. Notwithstanding the foregoing, in no event shall the parties hereto have a right to consequential, indirect, special, incidental, exemplary or punitive damages.

SECTION 7.15 Incorporation of Exhibits, Annexes and Schedules. The exhibits, annexes and schedules identified in this Agreement are incorporated herein by reference and made a part hereof.
