Notwithstanding anything to the contrary in this clause (a), materials provided to the other Party or its outside counsel may be redacted to remove references concerning the valuation of the Company, its business or its shares, or as regards Parent’s plans for conducting its business or that of the Company after the transactions contemplated by this Agreement.

(c) In furtherance and not in limitation of the covenants of the Parties contained in clauses (a) and (b), if any objections are asserted with respect to the transactions contemplated hereby under any Law or if any suit is instituted (or threatened to be instituted) by

any Governmental Entity or Self-Regulatory Organization or any private party challenging any of the transactions contemplated hereby as violative of any Law or which would otherwise prevent, materially impede or materially delay the consummation of the transactions contemplated hereby, each of Parent and the Company shall take, or cause to be taken, all other actions and do, or cause to be done, all other things necessary, proper or advisable to consummate and make effective the transactions contemplated hereby, including taking all such further action as may be necessary to resolve such objections, if any, as any Governmental Entity or Self-Regulatory Organization may assert under any Law with respect to the transactions contemplated hereby, and to avoid or eliminate each and every impediment under any Law that may be asserted by any Governmental Entity or Self-Regulatory Organization with respect to the transactions contemplated hereby so as to enable the Closing to occur as soon as reasonably practicable (and in any event no later than the Outside Date). Notwithstanding the foregoing and any other provision of this Agreement, in no event will Parent or its Subsidiaries be obligated to (i) propose, negotiate, commit to or effect, by consent decree, hold separate order or otherwise, the sale, divestiture or disposition of any assets or businesses of the Company or its Subsidiaries or the Surviving Entity or its Subsidiaries or otherwise take any actions or commit to take any actions that, in each case, would be reasonably likely to result in a Detriment individually or in the aggregate, or (ii) propose, negotiate, commit to or effect, by consent decree, hold separate order or otherwise, the sale, divestiture or disposition of any assets or businesses of Parent or its Subsidiaries (other than the Surviving Entity and its Subsidiaries as provided for in this Section 6.4(c)), or otherwise take or commit to take any actions that after the Closing Date would limit the freedom of Parent or its Subsidiaries’ freedom of action with respect to, or its ability to retain, one or more of its or its Subsidiaries’ businesses, product lines or assets, in each case, excluding any such sale, divestiture, disposition or action that to the Knowledge of Parent has been requested of Parent or proposed to Parent by any Governmental Entity or Self-Regulatory Organization prior to the date hereof.

(d) With regard to any Governmental Entity or Self-Regulatory Organization, neither the Company nor any of its Subsidiaries, nor any of their Representatives, shall, without Parent’s prior written consent in Parent’s sole discretion, discuss or commit to any divestiture transaction, extension of any waiting period under any Law or any agreement not to consummate the transactions contemplated by this Agreement, or discuss or commit to alter their businesses or commercial practices, or the businesses or commercial practices of Parent or any of Parent’s Subsidiaries (other than the Surviving Entity and its Subsidiaries as provided for in Section 6.4(c)), in any way, or otherwise take or commit to take any action that limits Parent’s ability to retain, or Parent’s freedom of action with respect to, any of the businesses, product lines or assets of Parent, the Company, the Surviving Entity or any of their respective Subsidiaries, or otherwise receive the economic benefits to Parent reasonably expected by Parent to be realized from the transactions contemplated by this Agreement, in each case, excluding any such commitments or actions that to Parent’s knowledge has been requested from Parent or proposed to Parent by any Governmental Entity or Self Regulatory Organization prior to the date hereof.

(e) The Boards of Directors of Parent and the Company shall each consider and make such determination with respect to the other Party, its Related Persons (as defined in the certificate of incorporation of Parent) and the Persons of which Parent and the Company are Related Persons, as required by any Governmental Entity and any Self-Regulatory Organization whose consent is required for the consummation of the Mergers. The Company, Parent and their

respective Boards of Directors shall use their respective reasonable best efforts to provide such information to the SEC, the European Regulators and any other Governmental Entity as is required with respect to the consideration by the SEC, the European Regulators and any other Governmental Entity as may be required to consummate and make effective the Mergers and the other transactions contemplated by this Agreement.

(b) Notwithstanding the foregoing, the Company may, prior to the receipt of the Company Member Approval, in response to a bona fide written Takeover Proposal for the Company or any of its Affiliates (so long as such Takeover Proposal was not initiated, solicited or facilitated, directly or indirectly, by a breach of this Section 6.5 and the Party in receipt of such Takeover Proposal has otherwise complied with the terms of this Section 6.5 with respect to such Takeover Proposal), and subject to compliance with Section 6.5(d):

provided, in each case, that the Board of Directors of the Company determines in good faith after consultation with its outside counsel and a financial advisor of nationally recognized reputation that (i) furnishing such information or participating in such discussions or negotiations would be reasonably necessary to perform its fiduciary duties and (ii) such Takeover Proposal is or is reasonably likely to lead to a Superior Proposal. The Company shall (A) immediately cease and cause to be terminated any existing activities, discussions or negotiations with any Persons or their Representatives conducted prior to the date of this Agreement with respect to any Takeover Proposal and will request the prompt return of any confidential information previously furnished to such Persons that has not been previously returned in connection therewith and (B) promptly inform its Representatives of the obligations undertaken in this Section 6.5. Without limiting the foregoing, any violation of the restrictions set forth in this Section 6.5 by any Representative of the Company or any of its Affiliates shall be deemed to be a breach of this Section 6.5 by the Company.

(c) As promptly as practicable after the receipt by the Company of any Takeover Proposal, and in any case within one (1) Business Day after the receipt thereof, the Company shall provide oral and written notice to Parent of (i) such Takeover Proposal, (ii) the identity of the Person making any such Takeover Proposal and (iii) a summary of all material terms and conditions of any such Takeover Proposal (including any amendments or material modifications thereto). The Company shall keep Parent informed on a timely basis of the status of any such Takeover Proposal (and, in any event, upon the request of Parent), including any amendments or material modifications to the terms and conditions thereof, and promptly, and in any case within one (1) Business Day after the receipt thereof, provide Parent with copies of a summary of the material terms of all Takeover Proposals (and amendments or material modifications thereof) and related agreements, draft agreements exchanged by the Parties and modifications thereof.

(d)(I) Neither the Board of Directors of the Company nor any committee thereof shall directly or indirectly (i) effect a Change in the Company Recommendation or (ii) approve any Alternative Agreement for the Company or any of its Affiliates.

(II) Notwithstanding the provisions of Section 6.5(d)(I), at any time prior the Company Member Approval, the Company Board of Directors may, in response to a Superior Proposal for the Company, effect a Change in Company Recommendation and recommend such Superior Proposal. Notwithstanding the foregoing, the Company Board of Directors may not effect such a Change in Company Recommendation unless (i) the Company Board of Directors shall have first provided prior written notice Parent that it is prepared to effect such a Change in Company Recommendation in response to a Superior Proposal, which notice shall attach the most current version of any written agreement relating to the transaction that constitutes such Superior Proposal and (ii) Parent does not make, prior to midnight, New York time, on the fifth (5^th) Business Day following the date of receipt of such notice (or, in the event

of a Takeover Proposal that has been materially revised or modified, prior to midnight, New York time, on the second (2^nd) Business Day following the date of receipt of notice of such material revision or modification, if later), a proposal that the Company Board of Directors determines in good faith, after consultation with a financial advisor of nationally recognized reputation, is at least as favorable, in the aggregate (taking into account all of the factors and other aspects of such proposal included in the definition of Superior Proposal), to its Members as such Superior Proposal (“Matching Bid”). The Company agrees that, during the five-(5)-Business-Day period (as extended, in accordance with the terms set forth above, in the case of a Takeover Proposal that has been materially revised or modified) prior to its effecting a Change in Company Recommendation it and its Representatives shall negotiate in good faith with Parent and its Representatives regarding any revisions to the terms of the transaction contemplated by this Agreement proposed by Parent.

(III) Notwithstanding the provisions of Section 6.5(d)(I), in circumstances other than as provided in Section 6.5(d)(II), at any time prior to the Company Member Approval, the Company Board of Directors may effect a Change in Company Recommendation if it determines in good faith in accordance with the advice of outside counsel, that such action is reasonably necessary for such Board of Directors to perform its fiduciary duties, but only after (A) providing written notice to Parent that it is prepared to make the determination permitted by this Section 6.5(d)(III) and setting forth the reasons therefore and (B) for a period of seven (7) Business Days after providing such notice, the Company Board of Directors or committee that is proposing to effect such Change in Company Recommendation negotiates with Parent in good faith to make such adjustments to the terms and conditions of this Agreement as would enable the Company Board of Directors to proceed with its recommendation of this Agreement and the transactions contemplated hereby, and at midnight, New York time, on the seventh (7^th) Business Day following the date of receipt of such notice at the end of such period, the applicable Board of Directors or committee maintains its determination permitted by this Section 6.5(d)(III) (after taking into account the proposed adjustments).

(e) For purposes of this Agreement:

“Superior Proposal” means any bona fide written Takeover Proposal made by a Third Party obtained not in breach of this Section 6.5 for or in respect of a Business Combination Transaction involving, or any transaction involving the purchase or acquisition of, (i) 100% of the voting power of the equity Securities of the Company or (ii) 100% of the consolidated assets of the Company and its Subsidiaries, which transaction the Board of Directors of the Company determines in good faith, after consultation with its outside counsel and a financial advisor of nationally recognized reputation, and taking into account, among other things, all legal, financial, regulatory and other aspects of the Takeover Proposal and this Agreement (including the expected timing of the proposed Business Combination Transaction as opposed to the NYSE/AMEX Merger), and taking into account any improved terms proposed by Parent, (x) would be, if consummated, more favorable from a financial point of view to its Members than the Mergers; (y) is reasonably likely to be consummated on the terms so proposed, taking into account all relevant financial, regulatory, legal and other aspects of such proposal, including any conditions, and the identity of the Third Party and (z) for

“Takeover Proposal” means any proposal or offer for, or any indication of interest in, (i) a merger, consolidation, business combination, share exchange, reorganization, recapitalization, liquidation, dissolution, or similar transaction involving the Company or AMEX, as applicable, or any of the Company’s Affiliates which represent, individually or in the aggregate, 20% or more of its consolidated assets with any Person other than Parent or its Affiliates (a “Third Party”), in which such Third Party or the stockholders of the Third Party immediately prior to consummation of such Business Combination Transaction will own, directly or indirectly, more than 20% of the outstanding equity Securities of the Company or AMEX, as applicable, immediately following such Business Combination Transaction, including the issuance by the Company or AMEX of more than 20% of any class of the voting equity Securities of the Company or AMEX, as applicable, as consideration for assets or securities of a Third Party or (ii) any direct or indirect acquisition, whether by tender or exchange offer or otherwise, by any Third Party of 20% or more of any class of outstanding equity Securities of the Company or AMEX or 20% or more of the consolidated assets of the Company or AMEX in a single transaction or a series of related transactions (any of the foregoing, a “Business Combination Transaction”).

(a) Parent shall honor all Employee Benefit Plans in accordance with their terms to the extent previously provided to Parent as in effect on the date hereof or as amended subsequently hereto in accordance with Section 5.1, provided, however, that nothing herein shall prohibit Parent or the Company or any of their respective Subsidiaries from amending or terminating any such plan in accordance with its terms. After the Effective Time and until December 31, 2008, Parent shall provide or cause to be provided, to employees of the Company and its Subsidiaries (“Company Employees”) base salary and annual cash bonus opportunities and welfare benefits that are no less favorable in the aggregate than those provided to the Company Employees immediately before the Effective Time, provided, that for this purpose, the welfare benefits provided under Parent Benefit Plans shall be considered no less favorable in the aggregate than those provided to Company Employees immediately prior to the Effective Time, provided, further, that Parent shall, to the extent Company Employees become eligible to participate in Parent Benefit Plans providing welfare benefits, (i) cause there to be waived any pre-existing condition or eligibility limitations or exclusions and actively-at-work requirements with respect to Company Employees and their eligible dependents to the extent such condition or limitations did not apply to such Company Employee immediately prior to the Effective Time and (ii) give effect, for the year in which the Company Employee becomes eligible to participate in such Parent Benefit Plan, for purposes of satisfying any deductible and maximum out-of-pocket limitations, to claims incurred and amounts paid by, and amounts reimbursed to, Company Employees and their eligible dependents under similar plans maintained by the Company in which such Company Employees and their eligible dependents participated immediately prior to such eligibility.

(c) Parent shall provide that any Company Employees who become participants in Parent Benefit Plans will be given credit under such plans and programs, for purposes of eligibility, vesting and benefit accrual thereunder, for all service recognized by the Company or any of its Subsidiaries as if such service were with Parent and its Subsidiaries, to the same extent such service was credited under a comparable plan of the Company, except (i) for purposes of any retiree welfare plan, (ii) as such service credit would result in a duplication of benefits, (iii) to the extent that any new plan is established by Parent that does not recognize service of similarly-situated employees of NYSE and its Subsidiaries and (iv) benefit accrual will not be provided under defined benefit pension benefit plans.

(d) This Section 6.6 shall inure exclusively to the benefit of and be binding upon the Parties hereto and their respective successors, assigns, executors and legal representatives.

Section 6.7 Fees and Expenses.

As used in this Agreement, “Expenses” includes all out-of-pocket expenses (including, all fees and expenses of counsel, accountants, investment bankers, experts and consultants to a Party hereto and its Affiliates) incurred by a Party or on its behalf in connection with or related to the authorization, preparation, negotiation, execution and performance of this Agreement and the transactions contemplated hereby, including the preparation, printing, filing and mailing, as the case may be, of the Proxy Statement/Prospectus and the Form S-4 and any amendments or supplements thereto, and the solicitation of the Company Member Approval and all other matters related to the transactions contemplated hereby.

Section 6.8 Directors’ and Officers’ Indemnification and Insurance. From and after the Effective Time, the Surviving Entity and Parent (the “Indemnifying Persons”) shall

(i) indemnify and hold harmless, against any costs or expenses (including attorney’s fees), judgments, fines, losses, claims, damages or liabilities incurred in connection with any claim, action, suit, proceeding or investigation, whether civil, criminal, administrative or investigative, and provide advancement of expenses to, all past and present directors and officers of the Company and the Company Subsidiaries (in all of their capacities) (the “Indemnified Persons”) to the same extent such persons are indemnified or have the right to advancement of expenses as of the date of this Agreement by the Company pursuant to the Company’s Constituent Documents and indemnification agreements, if any, in existence on the date hereof with any Indemnified Persons, (ii) honor the provisions regarding elimination of liability of directors, indemnification of officers and directors and advancement of expenses contained in the Company’s Constituent Documents immediately prior to the Effective Time and (iii) maintain for a period of six years after the Effective Time the current policies of directors’ and officers’ liability insurance and fiduciary liability insurance (“D & O Insurance”) maintained by the Company (provided that the Indemnifying Persons (or any successors) may substitute therefor policies of at least the same coverage and amounts containing terms and conditions which are, in the aggregate, no less advantageous to the insured) with respect to claims arising from facts or events that occurred on or before the Effective Time (including for acts or omissions occurring in connection with the approval of this Agreement and the consummation of the transactions contemplated hereby); provided, further, that in no event shall the Indemnifying Persons be required to expend in any one year more than 200% of the current annual premium expended by the Company and the Company Subsidiaries to maintain or procure such D & O Insurance immediately prior to the Effective Time (such 200% amount, the “Maximum Annual Premium”); provided, further, that if the annual premiums of such insurance coverage exceed such amount, the Indemnifying Persons shall be obligated to obtain a policy with the greatest coverage available for a cost not exceeding the Maximum Annual Premium. Notwithstanding the foregoing, the Company may, at Parent’s option, in lieu of maintaining the insurance described in clause (iii) of this Section 6.8, purchase a six-year “tail” prepaid policy on terms and conditions no less advantageous to the insured than the current directors’ and officers’ liability insurance and fiduciary liability insurance maintained by the Company; provided that the amount paid by the Company shall not exceed 200% of the aggregate amount per annum that the Company and its Subsidiaries paid for such coverage in the last full fiscal year. The obligations of the Indemnifying Persons under this Section 6.8 shall not be terminated or modified in such a manner as to adversely affect any Indemnified Person to whom this Section 6.8 applies without the consent of such affected Indemnified Person (it being expressly agreed that the Indemnified Persons to whom this Section 6.8 applies shall be third-party beneficiaries of this Section 6.8). The rights of any Indemnified Person under this Section 6.8 shall be in addition to any other rights such Indemnified Person may have under the certificate of incorporation or bylaws of the Indemnifying Persons or any of their Subsidiaries, under the DGCL, or otherwise.

If the Contingent Consideration shall not have been issued by the fifth anniversary of the Closing Date, neither Parent nor any of its Subsidiaries shall have any further obligation to issue the Contingent Consideration.

(3) The right to receive the Contingent Consideration shall be non-transferable and non-assignable except by operation of Law.

(b) Former Member Representative

Subject to the proviso in the preceding sentence and compliance with appropriate procedures to avoid the dissemination of material non-public information regarding Parent or any of its Subsidiaries, the Former Member Representative may communicate with Former Members.

If requested by the Parent, the Former Member Representative shall promptly furnish or cause to be furnished to the Parent and its Representatives such work papers, receipts and other documents and information relating to the calculation of the Former Member Representative Expenses.

(4) For the avoidance of doubt, the Former Member Representative shall not have the authority to and shall not enter into any Sale Arrangements.

(c) Parent, the Company and the Company Subsidiaries shall use their commercially reasonable efforts to cooperate in connection with the sale process, including without limitation, in obtaining one or more owner’s ALTA policy of title insurance (including all endorsements) and an ALTA survey(s) with respect to the Company Owned Real Properties, executing, acknowledging and delivering all customary owner’s/title affidavits (or other

customary documents as reasonably requested by such purchaser’s title insurer), executing and delivering all brokerage contracts and/or agreements, participating in any meetings or negotiations with any and all industrial development, economic development and/or Governmental Entities (the “Economic Development Entities”) relating to any arrangements concerning the Company Owned Real Properties (the “Economic Development Agreements”) and executing contracts of sale and other customary documents as reasonably requested or required to consummate such sale transaction. Promptly following the execution of this Agreement and continuing for so long as shall be reasonably necessary, Parent and the Company shall together (and neither party shall do so separately) meet with the Economic Development Entities for the purposes of renegotiating the Economic Development Agreements. Notwithstanding any provision to the contrary in this Agreement, with regard to the Company Owned Real Properties, (i) no preliminary or pre-sale, sale or other preparations, activities or communications whatsoever (including without limitation discussions with brokers or any other consultants, prospective buyers, or pre-marketing or marketing) shall be initiated, solicited, undertaken or participated in by any of the Parties or their Representatives with respect to any such pre-sale, sale or sale process and (ii) no provision of this Agreement shall be, nor shall be deemed to constitute, an intention or proposal to sell or prepare for sale or to initiate the sale process with respect to any of the Company Owned Real Properties, in any event until and unless the Parties have met with representatives of the Economic Development Entities with respect to the Economic Development Agreements. Following the Effective Time, Parent or its Subsidiaries shall use commercially reasonable efforts to, except as otherwise agreed between Parent and the Former Member Representative, (1) defend against any proceeding or litigation brought by a third party seeking to delay or prevent the sale of the Company Owned Real Properties or (2) bring such claims or actions that Parent in its reasonable judgment believes to be meritorious and advantageous against any potential buyer of the Company Owned Real Properties that has materially breached a Sale Arrangement to compel such buyer to perform its duties under such Sale Arrangement; provided, that (i) any costs fees and expenses (including all attorneys’ fees and expert’s and consultants’ fees) incurred in doing so shall be included in Building Sale Costs and, together with all other Building Sale Costs, shall be less than the Gross Amount in Parent’s reasonable estimation, and (ii) Parent shall not be required to take any action which, if taken, would be reasonably likely to have a materially negative effect on Parent’s business or reputation. Any intended or proposed sale of the Company Owned Real Properties shall be subject to Section 6.17(i) and, subject to Section 6.17(f), may include a provision permitting Parent, the Company or any of their respective Subsidiaries to lease the Company Owned Real Properties following the Sale Date.

(d) Subject to Section 6.17(c), Section 6.17(i) and Section 6.17(l), from the Closing Date until the earlier of the Sale Date or the three-year anniversary of the Closing Date (the “Company Sale Period”):

(1) The Former Member Representative shall be responsible for conducting the sale process with respect to the Company Owned Real Properties, provided, however, that, without Parent’s prior written consent, no letter of intent, memorandum, term sheet, contract, agreement, or other arrangement providing for the negotiation, option to purchase or sale of any Company Owned Real Properties (collectively, “Sale Arrangements”) shall be entered into unless and until (1) the cash price being paid in connection with such sale is in Parent’s reasonable estimation greater

than the Building Sale Costs and (2) Parent has consented to the other terms and conditions of such sale, including without limitation the identity and creditworthiness of the buyer, the buyer’s source of funds and/or financing, due diligence period and timing of the closing of such sale, which consent (except as provided in Section 6.17(f)) shall not be unreasonably withheld, conditioned or delayed;

(2) Parent shall be provided with, upon its request, such information and materials regarding the marketing and/or sale of the Company Owned Real Properties as Parent may reasonably request, including without limitation buyers’ financial statements and copies of all proposed Sale Arrangements (which information and materials shall be kept strictly confidential by Parent); and

(3) The Former Member Representative shall use its reasonable best efforts to negotiate the sale of the Company Owned Real Properties as promptly as practicable at the highest cash price reasonably available and on otherwise customary terms, including using a reputable real estate broker with knowledge of the downtown Manhattan real estate market.

(e) If no definitive contract providing for the Sale of all Company Owned Real Properties shall have been entered into and be in effect prior to the termination of the Company Sale Period, the Former Member Representative and Parent or a Subsidiary of Parent shall submit the Company Owned Real Properties to a sale by auction for a period of up to 120 days from the termination of the Company Sale Period (the “Auction Period”) (provided, that the closing date of any contract providing for the sale of the Company Owned Real Properties entered into pursuant to such auction may be outside of such 120 day period), shall mutually select a third party auctioneer with experience in auctioning commercial real properties and shall direct such auctioneer to, subject to the terms and conditions set forth in this Section 6.17, sell the Company Owned Real Properties at the highest cash price reasonably available; provided, however, that (1) unless otherwise consented to by Parent in writing, the bidding in such auction shall start at, and no bid will be accepted which shall be less than, Parent’s reasonable estimation of the Building Sale Costs and (2) the terms and conditions of such sale by auction, including without limitation the identity and creditworthiness of the buyer, the buyer’s source of funds and/or financing, due diligence period and timing of the closing of such sale, shall be subject to Parent’s consent, which consent (except as provided in Section 6.17(f)) shall not be unreasonably withheld, conditioned or delayed. If either, the auction provided for in this Section 6.17(e) does not produce a buyer for the Company Real Owned Properties or the Sale Arrangements entered into with a prospective buyer as a result of such auction are terminated, then the process described in this Section 6.17(e) shall be repeated.

(f) Notwithstanding anything herein to the contrary, Parent shall have the right to withhold its consent in its absolute discretion with respect to any Sale Arrangement (and without Parent’s prior consent which it shall have the right to withhold in its absolute discretion, no Sale Arrangement shall be entered into and no sale of the Company Owned Real Properties shall occur, whether before or after the Effective Time), if such Sale Arrangement or sale would create any continuing obligation or liability after the later of the Sale Date or the Effective Time on the part of Parent, the Company or any of their respective Affiliates (including, but not limited to any post-closing survival of seller representations and warranties, escrow or

indemnity); provided, however, Parent’s consent shall not be required if (1) such continuing obligation or liability (including the last day for any payment) shall (i) terminate within one year from the Sale Date and (ii) be expressed in an absolute maximum dollar amount in the applicable Sale Arrangement, which maximum dollar amount shall be a Building Sale Cost and (2) Building Sale Costs (including the maximum amount of such continuing obligation or liability) shall not reasonably be expected by Parent to exceed the Gross Amount.

(g) For the purposes of this Agreement:

Section 9.3 Interpretation; Construction.

(a) When a reference is made in this Agreement to Sections, Exhibits or Schedules, such reference shall be to a Section of or Exhibit or Schedule to this Agreement unless otherwise indicated. The table of contents and headings contained in this Agreement are for reference purposes only and shall not affect in any way the meaning or interpretation of this Agreement. Whenever the words “include,” “includes” or “including” are used in this Agreement, they shall be deemed to be followed by the words “without limitation.” The words “hereof”, “herein” and “hereunder” and words of similar import when used in this Agreement shall refer to this Agreement as a whole and not to any particular provision of this Agreement. References to “this Agreement” shall include the disclosure letters delivered pursuant hereto. All terms defined in this Agreement shall have the defined meanings when used in any certificate or

other document made or delivered pursuant hereto unless otherwise defined therein. The definitions contained in this Agreement are applicable to the singular as well as the plural forms of such terms and to the masculine as well as to the feminine and neuter genders of such terms.

(b) The Parties have participated jointly in negotiating and drafting this Agreement. In the event that an ambiguity or a question of intent or interpretation arises, this Agreement shall be construed as if drafted jointly by the Parties, and no presumption or burden of proof shall arise favoring or disfavoring any party by virtue of the authorship of any provision of this Agreement.

Section 9.4 Counterparts; Effectiveness. This Agreement may be executed in two or more counterparts, each of which shall be deemed to be an original but all of which shall constitute one and the same instrument. This Agreement shall become effective when each Party hereto shall have received counterparts thereof signed and delivered by the other Party hereto. Copies of executed counterparts transmitted by telecopy, telefax or electronic transmission shall be considered original executed counterparts for purposes of this Section 9.4 provided that receipt of copies of such counterparts is confirmed.

Section 9.5 Entire Agreement; Third-Party Beneficiaries.

(a) This Agreement (including the Exhibits and the Parties’ disclosure letters hereto) and the Confidentiality Agreement constitute the entire agreement, and supersede all prior agreements and understandings, both written and oral, between the Parties with respect to the subject matter hereof and thereof.

(b) 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 Person not a Party to this Agreement any rights, benefits or remedies of any nature whatsoever, other than Section 6.8 (which is intended to be for the benefit of the Persons covered thereby and may be enforced by such Persons).

Section 9.6 Severability. If any term or other provision of this Agreement is invalid, illegal or incapable of being enforced by any Law or public policy, all other terms and provisions of this Agreement shall nevertheless remain in full force and effect so long as the economic or legal substance of the transactions contemplated hereby is not affected in any manner materially adverse to any Party. Notwithstanding the foregoing, upon such determination that any term or other provision is invalid, illegal or incapable of being enforced, the Parties shall negotiate in good faith to modify this Agreement so as to effect the original intent of the Parties as closely as possible in an acceptable manner in order that the transactions contemplated hereby are consummated as originally contemplated to the greatest extent possible.

Section 9.7 Assignment. Neither this Agreement nor any of the rights, interests or obligations hereunder shall be assigned by any Party, in whole or in part (whether by operation of law or otherwise), without the prior written consent of the other Parties, and any attempt to make any such assignment without such consent shall be null and void. Subject to the preceding sentence, this Agreement will be binding upon, inure to the benefit of and be enforceable by the Parties and their respective successors and assigns.

Section 9.8 Amendment. This Agreement may be amended by the Parties, by action taken or authorized by their respective Boards of Directors, at any time before or after receipt of the Company Member Approval; provided that following the receipt of the Company Member Approval, no amendment shall be made which any applicable Law or regulation requires further approval by such Members without such further approval. This Agreement may not be amended except by an instrument in writing signed on behalf of each of the Parties.

Section 9.9 Extension; Waiver. At any time prior to the Effective Time, the Parties may, to the extent legally allowed, (a) extend the time for the performance of any of the obligations or other acts of the other Party, (b) waive any inaccuracies in the representations and warranties contained herein or in any document delivered pursuant hereto and (c) waive compliance with any of the agreements or conditions contained herein. Any agreement on the part of a Party hereto to any such extension or waiver shall be valid only if set forth in a written instrument signed on behalf of such Party. The failure of any Party to this Agreement to assert any of its rights under this Agreement or otherwise shall not constitute a waiver of those rights.

Section 9.10 GOVERNING LAW AND VENUE; WAIVER OF JURY TRIAL.

(a) THIS AGREEMENT SHALL BE DEEMED TO BE MADE IN AND IN ALL RESPECTS SHALL BE INTERPRETED, CONSTRUED AND GOVERNED BY AND IN ACCORDANCE WITH THE LAW OF THE STATE OF DELAWARE WITHOUT REGARD TO ITS RULES OF CONFLICT OF LAWS. The Parties hereby irrevocably submit to the exclusive jurisdiction of the courts of the State of Delaware and the Federal courts of the United States of America located in the State of Delaware in respect of all matters arising out of or relating to this Agreement the interpretation and enforcement of the provisions of this Agreement, and of the documents referred to in this Agreement, and in respect of the transactions contemplated hereby, and hereby waive, and agree not to assert, as a defense in any action, suit or proceeding for the interpretation or enforcement hereof or of any such document, that it is not subject thereto or that such action, suit or proceeding may not be brought or is not maintainable in said courts or that the venue thereof may not be appropriate or that this Agreement or any such document may not be enforced in or by such courts, and the Parties hereto irrevocably agree that all claims with respect to such action or proceeding shall be heard and determined exclusively in such a Delaware State or Federal court. The Parties hereby consent to and grant any such court jurisdiction over the person of such Parties solely for such purpose and over the subject matter of such dispute and agree that mailing of process or other papers in connection with any such action or proceeding in the manner provided in Section 9.2 or in such other manner as may be permitted by Law shall be valid and sufficient service thereof.

(b) EACH PARTY ACKNOWLEDGES AND AGREES THAT ANY CONTROVERSY WHICH MAY ARISE UNDER THIS AGREEMENT IS LIKELY TO INVOLVE COMPLICATED AND DIFFICULT ISSUES, AND THEREFORE EACH SUCH PARTY HEREBY IRREVOCABLY AND UNCONDITIONALLY WAIVES ANY RIGHT SUCH PARTY MAY HAVE TO A TRIAL BY JURY IN RESPECT OF ANY LITIGATION DIRECTLY OR INDIRECTLY ARISING OUT OF OR RELATING TO THIS AGREEMENT OR THE TRANSACTIONS CONTEMPLATED BY THIS AGREEMENT. EACH PARTY CERTIFIES AND ACKNOWLEDGES THAT (i) 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 THE FOREGOING WAIVER, (ii) EACH PARTY UNDERSTANDS AND HAS CONSIDERED THE IMPLICATIONS OF THIS WAIVER, (iii) EACH PARTY MAKES THIS WAIVER VOLUNTARILY AND (iv) EACH PARTY HAS BEEN INDUCED TO ENTER INTO THIS AGREEMENT BY, AMONG OTHER THINGS, THE MUTUAL WAIVERS AND CERTIFICATIONS IN THIS SECTION 9.10(b).

Section 9.11 Enforcement. The Parties hereto agree that irreparable damage would occur in the event that any provision of this Agreement was not performed in accordance with its specific terms or was otherwise breached. It is accordingly agreed that the Parties shall be entitled to an injunction or injunctions to prevent breaches of this Agreement and to enforce specifically the terms and provisions hereof in any court of competent jurisdiction, this being in addition to any other remedy to which they are entitled at law or in equity.
