3.3    This Amendment constitutes the legal, valid and binding obligation of each Borrower party thereto, enforceable against each such Borrower in accordance with its terms, except to the extent that enforceability may be limited by applicable bankruptcy, insolvency, moratorium, reorganization or other similar laws affecting the enforcement of creditors’ rights and the rights of creditors of insurers generally and to the supervisory powers of insurance regulatory agencies or by the effect of general equitable principles.

3.4    The representations and warranties made by any Borrower in the Loan Documents are true and correct on and as of the date hereof as if made on and as of the date hereof (except where such representation and warranty speaks of a specific date in which case such representation and warranty shall be true and correct as of such date).

4.3    Headings. The various headings of this Amendment are inserted for convenience only and shall not affect the meaning or interpretation of this Amendment or any provisions hereof.

4.4    Execution in Counterparts. This Amendment may be executed by the parties hereto in several counterparts, each of which shall be deemed to be an original and all of which shall constitute together but one and the same agreement.

4.5    Governing Law. THIS AMENDMENT AND THE RIGHTS AND OBLIGATIONS OF THE PARTIES HERETO SHALL BE GOVERNED BY AND CONSTRUED AND INTERPRETED IN ACCORDANCE WITH, THE LAW OF THE STATE OF NEW YORK.

4.6    Successors and Assigns. This Amendment shall be binding upon and shall inure to the benefit of the parties hereto and their respective successors and assigns. This Amendment is solely for the benefit of the parties hereto, and, no provision of this Amendment shall be deemed to confer upon any third parties (including, without limitation, any other creditors or parties in interest (including equity holders) of the Borrowers) any claim, remedy, liability, reimbursement, cause of action or other right.
