Confidential Information does not include, however, information which (i) is or becomes generally available to the public other than as a result of a disclosure by the Investor or its Representatives in violation of this Agreement, the Mutual Confidentiality Agreement, dated as of March 1, 2010, between the Company and an affiliate of the Investor, or other obligation of confidentiality, (ii) was available to the Investor on a non-confidential basis prior to its disclosure by the Company to the Investor or (iii) becomes available to the Investor on a non-confidential basis from a person (other than the Company) who is not prohibited from disclosing such information to the Investor by a legal, contractual or fiduciary obligation to the Company.

(c) Notwithstanding anything to the contrary contained in this Agreement, each Investor Designated Director shall be permitted to provide to the Investor and its Representatives information concerning the Company that the Investor Designated Director receives in his or her capacity as a director; provided, however, that with respect to any such information provided, the Investor and its Representatives shall be bound by the same restrictions on disclosure and use of confidential information as apply to each Investor Designated Director in his or her capacity as a director, in addition to any applicable restrictions under this Article 7.

(d) As used in this Article 7, the term “Company” includes the Company and all of its subsidiaries, and the term “Investor” includes the Investor and all of its affiliates (other than the Company).

SECTION 7.02 Furnishing of Information.

The Company shall provide the Investor and its Representatives with reasonable access to the books and records of the Company during normal business hours upon reasonable notice, including financial data (including projections) and operating data covering each of the Company, its business, operations and financial performance.

SECTION 8.04 Expenses. Except as otherwise specified in this Agreement, all costs and expenses, including fees and disbursements of counsel, financial advisors and accountants, incurred in connection with this Agreement and the transactions contemplated hereby shall be paid by the party incurring such costs or expenses.

SECTION 8.05 Governing Law. This Agreement shall be governed by, and construed in accordance with, the Laws of the State of Delaware. All actions and proceedings arising out of or relating to this Agreement shall be heard and determined exclusively in any Delaware state or federal court, in each case sitting in City of Wilmington, New Castle County. The parties hereto hereby (a) submit to the exclusive jurisdiction of any Delaware state or federal court, in each case sitting in City of Wilmington, New Castle County, for the purpose of any action 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, 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 is brought in an inconvenient forum, that the venue of the action is improper or that this Agreement or the transactions contemplated hereby may not be enforced in or by any of the above-named courts.

SECTION 8.06 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 contemplated hereby. Each of the parties hereto (a) certifies that no representative, agent or attorney of the 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 party hereto have been induced to enter into this Agreement and the transactions contemplated hereby, as applicable, by, among other things, the mutual waivers and certifications in this Section 8.06.

SECTION 8.07 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 in equity.

SECTION 8.08 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 8.09 Entire Agreement. This Agreement and the Related Agreements constitute the entire agreement between the parties with respect to the subject matter hereof and thereof and supersede all prior agreements and understandings, both written and oral, between the parties with respect to the subject matter hereof and thereof.

SECTION 8.10 Assignment. This Agreement shall not be assigned by operation of law or otherwise without the prior written consent of the other party.

SECTION 8.11 Amendment. This Agreement may not be amended or modified except (a) by an instrument in writing signed by, or on behalf of, the Company and the Investor or (b) by a waiver in accordance with Section 8.12.

SECTION 8.12 Waiver. Any party to this Agreement may (a) extend the time for the performance of any of the obligations or other acts of the other party or (b) waive compliance with any of the agreements of the other party or conditions to such party’s obligations contained herein. Any such extension or waiver shall be valid only if set forth in an instrument in writing signed by the party to be bound thereby. Any waiver of any term or condition shall not be construed as a waiver of any subsequent breach or a subsequent waiver of the same term or condition, or a waiver of any other term or condition of this Agreement. The failure of any party hereto to assert any of its rights hereunder shall not constitute a waiver of any of such rights. All rights and remedies existing under this Agreement are cumulative to, and not exclusive of, any rights or remedies otherwise available.

SECTION 8.13 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 contemplated hereby is not affected in any manner materially 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 contemplated hereby be consummated as originally contemplated to the fullest extent possible.

Accordingly, the parties hereto hereby waive the benefit of any rule of Law or any legal decision that would require, in cases of uncertainty, that the language of a contract should be interpreted most strongly against the party who drafted such language.

SECTION 8.16 Director Duties. The parties agree and acknowledge that all directors of the Company have fiduciary duties to all stockholders of the Company under applicable laws, rules and regulations. Nothing in this Agreement is intended to require any such director to breach or violate any such fiduciary duties. In addition, notwithstanding anything to the contrary in this Agreement, no provision hereof shall prevent, restrict, encumber or in any way limit the exercise of the fiduciary rights and obligations of any Investor Designated Director as a director, or his or her ability to vote on matters, influence management or the other directors or otherwise to discharge their fiduciary or other duties as directors. The Company shall not approve or recommend to its stockholders any transaction or resolution, or approve, recommend or take any other action (other than those expressly contemplated by this Agreement) that would restrict the right of any Investor Designated Director to vote on any matter as such director believes appropriate in light of his or her duties as a director or the manner in which an Investor Designated Director may participate in his or her capacity as a director in deliberations or discussions at meetings of the Board or any committee thereof.

SECTION 8.17. Investor Affiliates. Investor covenants that it shall cause any and all affiliates to comply with the terms and conditions set forth herein with respect any shares of capital stock held any such affiliates.
