         Re: Westport Resources Corporation, Registration Statement Form S-1
             (Registration No. 333-40422)


Ladies and Gentlemen:

         We have acted as counsel to Westport Resources Corporation, a Delaware
corporation (the "COMPANY"), in connection with the registration, pursuant to a
registration statement on Form S-1, as amended (the "REGISTRATION STATEMENT"),
filed with the Securities and Exchange Commission under the Securities Act of
1933, as amended (the "ACT"), of the offering and sale by the Company of up to
7,200,000 shares (the "COMPANY SHARES") of the Company's common stock, par value
$.01 per share ("COMMON STOCK"), and the offering and sale by the selling
stockholders listed in the Registration Statement (the "SELLING STOCKHOLDERS")
of up to 1,500,000 shares of Common Stock (the "SELLING STOCKHOLDER SHARES")
sold pursuant to the terms of an underwriting agreement to be executed by the
Company, the Selling Stockholders and Credit Suisse First Boston Corporation on
behalf of itself, Bank of America Securities LLC, Donaldson, Lufkin & Jenrette
Securities Corporation, Lehman Brothers Inc. and Petrie Parkman & Co., Inc. (the
"UNDERWRITERS"). The Company Shares and the Selling Stockholder Shares are
collectively referred to as the "SHARES."

         We have examined originals or certified copies of such corporate
records of the Company and other certificates and documents of officials of the
Company, public officials and others as we have deemed appropriate for purposes
of this letter. We have assumed the genuineness of all signatures, the
authenticity of all documents submitted to us as originals, the conformity to
authentic original documents of all copies submitted to us as conformed and
certified or reproduced copies.
