company existing under the laws of Bermuda (the "Company" or "Platinum
Holdings"), and Platinum Underwriters Finance, Inc., a company incorporated
under the laws of the State of Delaware ("Platinum Finance"), in connection with
the filing by the Company and Platinum Finance with the United States Securities
and Exchange Commission (the "Commission") under the Securities Act of 1933, as

the Company's senior and subordinated debt securities ("Platinum Holdings Debt

Holdings Debt Securities will be established by or pursuant to resolutions of
the Board of Directors of the Company or a duly authorized committee thereof as
part of the corporate action taken and to be taken relating to the issuance of
the Platinum Holdings Debt Securities.

         The Platinum Finance Debt Securities and the Guarantees may be issued
under a Senior Indenture, among Platinum Finance, as Issuer, the Company, as
Guarantor, and JPMorgan Chase Bank, N.A., as Trustee (the "Platinum Finance
Senior Indenture") or a Subordinated Indenture (the "Platinum Finance

collectively as the "Senior Indentures"; the Platinum Holdings Indentures and
the Platinum Finance Indentures shall be referred to collectively as the
"Indentures." Certain terms of the Platinum Finance Debt Securities will be

Securities. Certain terms of the Guarantees will be established by or pursuant
to resolutions of the Board of Directors of the Company or a duly authorized
committee thereof as part of the corporate action taken and to be taken relating
to the issuance of the Guarantees.

         The Warrants may be issued pursuant to the terms of one or more warrant
agreements (the "Warrant Agreements") to be entered into prior to the issuance
of the Warrants, with certain terms of the Warrants to be established by or
pursuant to resolutions of the Board of Directors of the Company or a duly

certain terms of the Receipts to be established by or pursuant to resolutions of
the Board of Directors of the Company or a duly authorized committee thereof as
part of the corporate action taken and to be taken relating to the issuance of
the Receipts.

         In connection therewith, we have examined (a) the Registration
Statement, (b) the Senior Indentures and Subordinated Indentures, (c) the
forms of the senior notes and subordinated notes included in the Senior
Indentures and Subordinated Indentures, respectively and (d) the forms of
Guarantees included in the Platinum Finance Indentures. In addition, we have
examined the originals (or copies certified or otherwise identified to our
satisfaction) of such other agreements, instruments, certificates, documents
and records and have reviewed such questions of law and made such inquiries as
we have deemed necessary or appropriate for the purposes of the opinions
rendered herein.

         In such examination, we have assumed, without inquiry, the legal
capacity of all natural persons, the genuineness of all signatures on all
documents examined by us, the authenticity of all documents submitted to us as
originals, the conformity to the original documents of all such documents
submitted to us as copies and the authenticity of the

records of each of the Company and Platinum Finance are maintained in accordance
with proper corporate procedures. As to any facts material to our opinions, we
have, when relevant facts were not independently established, relied upon the
aforesaid agreements, instruments, certificates, documents and records and upon
statements and certificates of officers and representatives of each of the
Company and Platinum Finance and public officials.

      Based upon the foregoing, and subject to the limitations, qualifications
and assumptions stated herein, we are of the opinion that:

      1.    Assuming that (i) the Platinum Holdings Indentures, any Platinum
            Holdings Debt Securities and any supplemental indenture to be

            violate any applicable law, rule or regulation or result in a
            default under or breach of any agreement or instrument binding upon
            the Company and comply with any requirement or restriction imposed
            by any court or governmental or regulatory body having jurisdiction
            over the Company; and (v) such Platinum Holdings Debt Securities
            have been duly executed and authenticated in accordance with the

            supplement relating thereto, and paid for by any purchaser or
            underwriter or similar person in accordance with the underwriting
            agreement, purchase agreement or similar agreement relating to such
            Platinum Holdings Debt Securities, such Platinum Holdings Debt
            Securities will constitute valid and binding obligations of the
            Company enforceable in accordance with their terms, subject to
            applicable bankruptcy, insolvency, fraudulent conveyance,
            reorganization, moratorium, rehabilitation, fraudulent transfer or

         The opinions rendered herein are limited to the laws of the State of

and we assume the validity of the Platinum Holdings Indentures, the Warrant
Agreement, the warrant certificate, the Deposit Agreement, the Receipts and the

Subordinated Indenture, any Guarantee issued pursuant to a Platinum Finance
Subordinated Indenture, Warrant, Warrant Agreement, warrant certificate, Deposit
Agreement, Receipt, Purchase Contract or Purchase Unit, and that Platinum
Finance has not yet prepared any form of Platinum Finance Subordinated
Indenture. Our opinions above are rendered based upon the assumption that such

be acceptable to us.

         We consent to the filing of this opinion with the Commission as an
exhibit to the Registration Statement and to the use of our name under the
