become effective upon the execution and delivery hereof by the XL Parties, the
Required Banks and the Administrative Agent, provided, however, that no Loans

            (d) Details, Proceedings, Notes and other Documents. All legal
      details and proceedings in connection with the transactions contemplated
      by this Amendment shall be satisfactory to the Administrative Agent and

            (f) Representation and Warranties. The representations and
      warranties contained in Article III of the Credit Agreement shall be true

      this First Amendment (it being understood that references in such Article
      III to the Credit Agreement shall be deemed for this purpose to be
      references to this First Amendment and to the Credit Agreement as amended
      hereby) and the Administrative Agent shall have received a certificate of
      XL Capital and, insofar as is applicable to it, XL America, to such
      effect.

            SECTION 4. Effect of Amendment. The Credit Agreement, as amended by
this Amendment, is in all respects ratified, approved and confirmed and shall,
as so amended, remain in full force and effect.

            SECTION 5. Governing Law. This Amendment shall be deemed to be a
contract under the laws of the Commonwealth of Pennsylvania and for all purposes
shall be governed by and construed and enforced in accordance with the laws of
said Commonwealth.

            SECTION 6. Counterparts. This Amendment may be executed in any
number of counterparts and by the different parties hereto on separate
counterparts, each of which, when so executed, shall be deemed an original, but
all such counterparts shall constitute but one and the same instrument.
