The Stockholder has full power and capacity to execute and deliver this Agreement and to perform his obligations hereunder. This Agreement - 5 -

has been duly executed and delivered by the Stockholder, and, in the event the Stockholder is an individual and is married and the Shares constitute community property or otherwise require spousal approval in order for this Agreement to be a legally valid and binding obligation of the Stockholder, this Agreement has been duly executed and delivered by the Stockholder’s spouse. Assuming this Agreement constitutes a valid and binding obligation of Parent, this Agreement constitutes a valid and binding obligation of the Stockholder, enforceable against the Stockholder in accordance with its terms, except as enforcement may be limited by applicable bankruptcy, insolvency, reorganization, moratorium and other similar laws affecting creditors’ rights generally and by general principles of equity.

The execution, delivery and performance by the Stockholder of this Agreement, and the consummation by the Stockholder of the transactions contemplated hereby, require no action by or in respect of, or filing with, any Governmental Entity.

(f) No Litigation. There are no Actions pending or, to the knowledge of the Stockholder, threatened against the Stockholder, or any order to which the Stockholder is subject, except, in each case, for those that, individually or in the aggregate, would not reasonably be expected to, in any material respect, impair or adversely affect the ability of the Stockholder to perform its obligations under this Agreement. 10.
