The foregoing sentence shall not apply to the transfer of any or all of the Restricted Securities owned by Sponsor (I) to any Permitted Transferee (as defined below), (II) to PubCo in accordance with the requirements of the Business Combination Agreement, or (III) required by virtue of the laws of New York; provided, however, that in the of cases of clauses (I) it shall be a condition to such transfer that the transferee executes and delivers to PubCo an agreement stating that the transferee is receiving and holding the Restricted Securities subject to the provisions of this Agreement applicable to Sponsor, and there shall be no further transfer of such Restricted Securities except in accordance with this Agreement.

Each party agrees that a final judgment in any Action shall be conclusive and may be enforced in other jurisdictions by suit on the judgment or in any other manner provided by Law.
