FURTHER ASSURANCES

From time to time after the date hereof, and without any further consideration, each of the Parties shall execute, acknowledge and deliver additional instruments, notices and other documents, and will do all such other acts and things, all in accordance with applicable law, as may be necessary or appropriate to more fully and effectively carry out the purposes and intent of this Agreement. Without limiting the generality of the foregoing, the Parties acknowledge that the Parties have used their good faith efforts to identify all of the assets being contributed as required in connection with this Agreement. It is the express intent of the Parties that the Company Group own all assets necessary to operate the assets that are identified in this Agreement and in the Registration Statement. To the extent that any assets were not identified but are necessary to the operation of the assets that are so identified in this Agreement and in the Registration Statement, then the intent of the Parties is that all such unidentified assets are intended to be conveyed to the Company Group pursuant to this Agreement. To the extent any such assets are identified at a later date, the Parties shall take all appropriate action required in order to convey such assets to the applicable member of the Company Group. Likewise, to the extent that any assets that are conveyed to the Company Group hereunder are later identified by the Parties as assets that the Parties did not intend to convey to the Company Group as reflected in the Registration Statement, the Parties shall take all appropriate action required to convey such assets to the appropriate Party.

Furthermore, without limiting any liabilities or other remedies of the Parties applicable under this Agreement or any other agreements, if and to the extent that the valid, complete and perfected transfer or assignment of any assets by any Party to any member of the Company Group or the acquisition of any assets from any Party by any member of the Company Group would be a violation of applicable law, or require any additional consents, approvals or notifications in connection with the transfer of such assets by any Party to any member of the Company Group that have not been obtained or made by the Effective Time, then, unless the Parties shall otherwise mutually determine, the transfer or assignment of such assets to such member of the Company Group or the assumption of such assets by such member of the Company Group, as the case may be, shall be automatically deemed deferred and any such purported transfer, assignment or assumption shall be null and void until such time as all legal impediments are removed or such consents, approvals and notifications have been obtained or made. Notwithstanding the foregoing, in such event the applicable Party shall (a) hold such assets in trust for the benefit of the Company Group, (b) not transfer or assign such assets, in whole or in part, other than with the prior consent of the Company, and (c) use reasonable best efforts to assure that each member of the Company Group receives all of the benefits of the assets attempted to have been transferred to it until such time as the attempted transfer is complete, and each member of the Company Group shall bear all costs associated with such assets (except costs associated with the attempted transfer or perfecting such transfer, and subject to offset of any benefits of the assets not received by the Company Group against associated costs incurred by the applicable Party) as if the transfer had been valid and complete.

Upon such determination that any term or other provision is invalid, illegal or incapable of being enforced, the court, administrative agency or arbitrator shall interpret this Agreement so as to effect the original intent of the Parties as closely as possible in an acceptable manner to the end that transactions contemplated hereby are fulfilled to the fullest extent possible.
