(a) The parties hereto acknowledge and 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, and further acknowledge and agree that money damages are an inadequate remedy for the breach of this Agreement because of the difficulty of ascertaining the amount of damage that would be suffered in the event of such breach.

(b) The parties hereto further agree that they shall not be permitted or have the right to terminate or suspend performance of any provision of this Agreement, it being agreed that all provisions of this Agreement shall continue and be specifically enforceable in all events and under all circumstances until terminated pursuant to the terms of this Agreement, regardless of any events, occurrences, actions or omissions before or after the date hereof. In furtherance of the foregoing, the parties hereto agree that they shall not be permitted to, and shall not, bring any claim seeking to terminate or suspend performance of any provision of this Agreement or seeking any determination that any provision of this Agreement (including, without limitation, this Section 6.11) is invalid, inapplicable or unenforceable.

Section 6.12 Transfers to Affiliates. In the event of any Transfer of capital stock of the Company by any party hereto to an Affiliate of such party, prior to the effectiveness of such Transfer, such Transferee shall execute a joinder to this Agreement and shall otherwise agree to be bound by the provisions of this Agreement in the same manner as the Transferor. The Transferor and the Transferee shall be jointly and severally responsible for the obligations of the Transferor under this Agreement.
