To the fullest extent permitted by applicable law, the Sponsor, its Affiliated Companies or any of the Exempted Persons shall not have any fiduciary duty to refrain from engaging directly or indirectly in the same or similar business activities or lines of business as the Corporation or any of its Affiliated Companies, and the Sponsor, its Affiliated Companies or any of the Exempted Persons shall not be liable to the Corporation or its stockholders for breach of any fiduciary or other duty (whether contractual or otherwise) solely by reason of any such activities of the Sponsor, its Affiliated Companies or any of the Exempted Persons. To the fullest extent permitted by applicable law, the Corporation, on behalf of itself and its Affiliated Companies, renounces any interest or expectancy of the Corporation and its Affiliated Companies in, or in being offered an opportunity to participate in, business opportunities that are from time to time presented to the Sponsor, its Affiliated Companies or any of the Exempted Persons, even if the opportunity is one that the Corporation or its Affiliated Companies might reasonably be deemed to have pursued or had the ability or desire to pursue if granted the opportunity to do so, and the Sponsor, its Affiliated Companies and the Exempted Persons shall have no duty to communicate or offer such business opportunity to the Corporation or its Affiliated Companies and, to the fullest extent permitted by applicable law, shall not be liable to the Corporation, any of its Affiliated Companies or its stockholders for breach of any fiduciary or other duty (whether contractual or otherwise), as a director, officer or stockholder of the Corporation solely, by reason of the fact that the Sponsor, its Affiliated Companies or any such Exempted Person pursues or acquires such business opportunity, sells, assigns, transfers or directs such business opportunity to another person or fails to present such business opportunity, or information regarding such business opportunity, to the Corporation or any of its Affiliated Companies.

Section 3. Certain Matters Deemed Not Corporate Opportunities.
