     7.1 Amendment. This Agreement may be amended or modified in whole or in part any time by an agreement in writing executed in the same manner as this Agreement, provided, however, that no amendment shall be made that changes the terms of this Agreement in any material respect and that requires the further approval or proceedings of any insurance Governmental Authority without such approval having first been obtained or such proceedings having been first completed.
