1.4 Holdco Ownership and Arrangements.

(a) Prior to the execution of the Merger Agreement, the Parties shall (i) incorporate Holdco and shall cause Holdco to incorporate Merger Sub and other intermediate holding companies as requested by the Financing Banks (if any) and (ii) agree in good faith the memorandum and articles of association of Holdco, Merger Sub and other intermediate holding companies (if any) and the memorandum and articles of association of Merger Sub shall become the memorandum and articles of association of the Surviving Company at the Closing.

(b) Prior to the execution of the Merger Agreement, the Parties or their respective Controlled Affiliates shall negotiate in good faith and enter into a term sheet for the shareholders agreement of Holdco, which shareholders agreement will be entered into by the Parties or their respective Controlled Affiliates promptly after the Closing.

(c) To finance a portion of the cash needed by Holdco for payment of the consideration in the Transaction, (i) each Party shall, to the extent Owning any Company Shares, enter into a roll-over agreement in connection with the execution of the Merger Agreement in customary form pursuant to which it will contribute at the Closing all Company Shares Owned by it to Holdco, and (ii) each Sponsor shall deliver an equity commitment letter in customary form, pursuant to which (and subject to the terms and conditions thereof) it will fund, at the Closing, cash to Holdco in an amount no less than as set forth opposite its name in Schedule B attached hereto (each Sponsor’s “Minimum Commitment Amount”), in each case in exchange for proportionate newly issued equity interests in Holdco.

(d) The relative Ownership of Holdco by the Parties shall be based on their relative capital contributions to Holdco pursuant to Section 1.4(c) (with the Company Shares contributed by the Parties pursuant to Section 1.4(c)(i) being valued at the same per share consideration as provided in the Merger Agreement), except as otherwise agreed to by all of the Parties in writing.

regarding any such admission in advance of such admission. Notwithstanding the foregoing, the Parties agree that, without the prior written consent of each of the Principal Consortium Members, no Additional Sponsor shall be added if such admission pursuant to this Section 1.4(e) shall result in the aggregate Company Shares Owned by the Consortium exceeding 4.9% or otherwise result in any obligation on any Party to file a Schedule 13D beneficial ownership report with the U.S. Securities and Exchange Commission. Any Additional Sponsor admitted to the Consortium pursuant to this Section 1.4(e) shall execute an adherence agreement to this Agreement substantially in the form attached hereto as Schedule C (the “Adherence Agreement”). Upon the admission of any Additional Sponsor, Schedule B shall be updated to reflect the amount of cash committed by such Additional Sponsor.

Each Party agrees that it will cause Holdco and Merger Sub not to waive any conditions under or agree to any amendment of the Merger Agreement without the prior written consent of each of the Principal Consortium Members.

The Consortium may from time to time engage additional Advisors that are approved by the Chairman to represent the Consortium in connection with the Transaction. The Parties agree and acknowledge that because of the types of clients which Advisors advise and the type of engagements in which Advisors are involved, Advisors may be requested to act for other persons on other matters where the interests of the other persons may be adverse to the Parties or their respective Affiliates in this or other matters, and that to the extent permitted by law, the engagement of Advisors in connection with the Transaction will not preclude any Advisor from acting for other persons on matters that are not substantially related to this or such other engagements, even though the interests of such persons may be adverse to the Parties or their respective Affiliates in this matter or in other matters.

(b) Except as otherwise provided in Section 2.3(a), if a Party requires separate representation in connection with specific issues arising out of the Transaction, such Party may retain other Advisors to advise it; provided, that such Party shall (i) provide prior notice to the other Parties of such retention and (ii) be solely responsible for the fees and expenses of such separate Advisors.

6.2 Confidentiality.

(a) Each Party agrees to keep confidential and to use only for the purpose of evaluating, pursuing and implementing the Transaction all information that the Company, another Party or any of their respective Representatives (each, a “Disclosing Party”) furnishes or otherwise makes available to a Party (the “Receiving Party”) and its Representatives, including any technical, scientific, trade secret or other proprietary information of the Company or the disclosing Party with which the Receiving Party or its Representatives may come into contact in the course of its investigation, and whether oral, written or electronic (collectively, the “Evaluation Material”). Notwithstanding the foregoing, the term “Evaluation Material” does not include information that (A) was available to the Receiving Party without a duty of confidentiality to the applicable Disclosing Party in breach of this Agreement prior to the disclosure by such Disclosing Party, (B) is or becomes available to a Receiving Party on a non-confidential basis from a source other than the applicable Disclosing Party, provided that such other source is not known by the Receiving Party to be bound by a confidentiality obligation to the applicable Disclosing Party or is otherwise prohibited from disclosing the information to the Receiving Party, (C) is or becomes generally available to the public (other than as a result of a breach by the Receiving Party or its Representatives of this Agreement) or (D) is independently developed by the Party or its Representatives without use of any Evaluation Material.

(b) Each Party agrees that neither it nor any of its Representatives will, without the prior written consent of the other Parties, directly or indirectly, disclose to any other person (excluding any of its Affiliates and Representatives), (i) the fact that discussions or negotiations may take place, are taking place or have taken place concerning a Transaction or any of the terms or other facts relating thereto, including the status thereof, but not including any Evaluation Material, (ii) the existence or the terms of this Agreement or (iii) that it or its Representatives have received or produced any Evaluation Material (items (i), (ii) and (iii), collectively, “Transaction Information”); provided, however, that each Party may disclose Transaction Information to the extent (x) required by, and pursuant to, Section 6.3(b), or (y) it has received the written opinion of its outside counsel that it is required to make such disclosure in order to avoid violating the U.S. federal securities laws, and, in the case of clauses (x) or (y), the requirement to make such disclosure does not arise from its breach of this Agreement; and, provided, further, that in the case of clause (y), to the extent legally permissible and reasonably practicable the Party will notify the other Parties prior to making any such disclosure by providing the other Parties with the text of the intended disclosure at least 24 hours prior to making the disclosure, and will seek to narrow the intended disclosure to the extent the other Parties reasonably so request.

(c) Subject to Section 6.2(d), upon the request of the Company, ABG or Boyu, each Party shall (and shall cause its Representatives and Affiliates to), at its election, promptly deliver to the Company or destroy all copies of the Evaluation Material, including that which is contained in any notes or other materials prepared by such Party or its Representatives, without retaining any copy thereof, including, to the extent practicable, expunging all such Evaluation Material from any computer, word processor or other device containing such information. If requested by the Company, ABG or Boyu, an appropriate officer of the Party will certify to the Company, ABG or Boyu, as applicable, that all such material has been so delivered or destroyed. Notwithstanding the foregoing, (i) each Party’s legal department and/or outside counsel may keep one copy of the Evaluation Material (in electronic or paper form) and each Party’s Representatives may keep one copy of the Evaluation Material as required by bona fide policies and procedures implemented by such Representatives in order to comply with applicable law, regulation, professional standards or reasonable business practice and (ii) each Party and its Representatives may retain Evaluation Material to the extent it is “backed-up” on the Party’s or its Representatives’ (as the case may be) electronic information management and communications systems or servers, is not available to an end user and cannot be expunged without considerable effort. Any and all duties and obligations

-8-

existing under this Agreement shall remain in full force and effect for the term set forth in Section 6.2(d), notwithstanding the delivery or destruction of the Evaluation Material required by this Section 6.2(c). The Party also agrees to notify the Company promptly upon its determination to cease to consider a Transaction.

(d) Each Party acknowledges that, in relation to any Evaluation Material or Transaction Information received from a Disclosing Party, the obligations contained in this Section 6.2 shall continue to apply for a period of 12 months following termination of this Agreement pursuant to Section 5.1, 5.2 or 5.3, unless otherwise agreed in writing.

6.3 Permitted Disclosures.

(a) A Party may disclose Transaction Information or Evaluation Material to its Affiliates or Representatives for the purpose of assisting the Party in its evaluation, pursuit and implementation of a Transaction so long as the Party causes its Affiliates or Representatives to treat the Transaction Information or Evaluation Material in a confidential manner and as provided in this Section 6.3.

(b) In the event that a Party or any of its Representatives or Affiliates are required to disclose any Transaction Information or Evaluation Material by law or in connection with a judicial or administrative proceeding (by oral questions, interrogatories, requests for information or documents, subpoena, civil investigation demand or similar process) or pursuant to a formal request from a regulatory examiner, to such regulatory examiner, it will provide the other Parties with prompt and, to the extent legally permissible and reasonably practicable, prior notice of such requirement(s). Each Party also agrees, to the extent legally permissible and reasonably practicable, to provide the other Parties, in advance of any such disclosure, with a list of any Transaction Information or Evaluation Material it intends to disclose (and, if applicable, the text of the disclosure language itself) and to reasonably cooperate with the other Parties to the extent the other Parties may seek to limit such disclosure, including, if requested, taking all reasonable steps, at the sole expense of the Party seeking to limit such disclosure, to resist or avoid any such judicial or administrative proceedings referred to above. If and to the extent, in the absence of a protective order or the receipt of a waiver from the other Parties after a request in writing therefor is made by the Party (such request to be made as soon as practicable to allow the other Parties a reasonable amount of time to respond thereto), the disclosing Party or its Representatives or its respective Affiliates are legally required to disclose Transaction Information or Evaluation Material to any tribunal or regulatory examiner to avoid censure or penalty, the disclosing Party will limit such disclosure to that which is legally required and will use reasonable efforts to obtain assurances that confidential treatment will be accorded to any Transaction Information or Evaluation Material that the disclosing Party is so required to disclose, and thereafter it may disclose such information without liability hereunder.
