Dear Sirs

We have been asked to provide this legal opinion to you with regard to the laws
of the Cayman Islands in connection with the registration of an initial public
offering of [ -- ] Class A Common Shares of par value US$0.0001 each (the
"SHARES") of United National Group, Ltd. (the "Company") under the United States
Securities Act of 1933, as amended, on Form S-1 initially filed with the
Securities and Exchange Commission on [ -- ] 2003 (as amended through the date
hereof, the "REGISTRATION STATEMENT").

For the purposes of giving this opinion, we have examined the following
documents:

1.    Certificate of Incorporation of the Company dated 26 August 2003 and
      Certificate of Incorporation on Change of Name dated 11 September 2003
      (the "CERTIFICATES OF INCORPORATION");

2.    certified copies of the Amended and Restated Memorandum and Articles of
      Association of the Company dated [ -- ] December 2003 (the "MEMORANDUM AND
      ARTICLES OF ASSOCIATION"); and

3.    a Certificate of Good Standing dated [ -- ] December 2003 issued by the
      Register of Companies.

We are Attorneys-at-Law in the Cayman Islands and express no opinion as to any
laws other than the laws of the Cayman Islands in force and as interpreted at
the date hereof.

We are of the opinion that under, and subject to, the laws of the Cayman
Islands:



WALKERS                                                                   Page 2

1.    The Company is a limited liability exempted company duly incorporated,
      validly existing and in good standing under the laws of the Cayman
      Islands.

2.    The Shares have been duly authorized and, upon issuance, delivery and
      payment therefor in the manner contemplated by the Registration Statement,
      will be validly issued, fully paid and non-assessable.

We have assumed that:

1.    the Certificates of Incorporation and the Memorandum and Articles of
      Association of the Company are authentic and that all signatures and seals
      on the Certificates of Incorporation and the Memorandum and Articles of
      Association of the Company are genuine.

2.    The Minute Book of the Company provided to us by the Registered Office of
      the Company (the "REGISTERED OFFICE") and examined by us on [ -- ]
      December 2003 contains a complete and accurate record of the business
      transacted by the Company.

3.    The corporate records of the Company provided to us by the Registered
      Office and examined by us on [ -- ] December 2003 constitute its complete
      corporate records and that all matters required by law and the Memorandum
      and Articles of Association to be recorded therein are so recorded.

4.    With respect to certain factual matters material to our opinion, we have
      relied upon representations from, or certificates of directors and
      officers of the Company. In making such examination and rendering the
      opinions set forth above, we have assumed without verification the
      genuineness of all signatures, the authenticity of all documents submitted
      to us as originals, the authenticity of the originals of such documents
      submitted to us as certified copies, the conformity to originals of all
      documents submitted to us as copies, the authenticity of the originals of
      such latter documents, and that all documents submitted to us as certified
      copies are true and correct copies of such originals.

5.    Each of the Shares issued by the Company is fully paid up.

To maintain the Company in good standing under the laws of the Cayman Islands,
annual filing fees must be paid and returns made to the Registrar of Companies.

This opinion is limited to the matters referred to herein and shall not be
construed as extending to any other matter or document not referred to herein.
This opinion is given solely for your benefit in relation to this transaction
and may not be relied upon by any other person without our prior written
consent.
