         Re:      Registration Statement on Form S-4

Ladies and Gentlemen:

         I am the General Counsel of Westport Resources Corporation, a Nevada
corporation ("WESTPORT"). This letter is prepared in connection with the
registration, pursuant to a registration statement on Form S-4 (as may be
amended from time to time, the "REGISTRATION STATEMENT"), filed with the
Securities and Exchange Commission under the Securities Act of 1933, as amended
(the "ACT"), of (i) the proposed offer by Westport to exchange (the "EXCHANGE
OFFER") up to $125,000,000 of its 8 1/4% Senior Subordinated Notes Due 2011
issued in a private offering on April 3, 2003 (the "OLD NOTES") for an equal
principal amount of its 8 1/4% Senior Subordinated Notes Due 2011 to be
registered under the Act (the "EXCHANGE NOTES") and (ii) the guaranty of the
Exchange Notes (the "SUBSIDIARY GUARANTY") by each of Westport Overriding
Royalty LLC, a Colorado limited liability company ("WORLLC"), Westport Argentina
LLC, a Colorado limited liability company ("WALLC"), Horse Creek Trading &
Compression Company LLC, a Colorado limited liability company ("HORSE CREEK,"
and together with WORLLC and WALLC, the "COMPANIES"), and Jerry Chambers
Exploration Company, a Colorado general partnership (the "PARTNERSHIP;" together
with the Companies, collectively, the "SUBSIDIARY GUARANTORS").

         The Old Notes have been, and the Exchange Notes will be, issued
pursuant to that certain Indenture, dated as of November 5, 2001, among the
Company, the subsidiary guarantors from time to time parties thereto and The
Bank of New York, as trustee (the "TRUSTEE") (the "ORIGINAL INDENTURE"), as
supplemented by the First Supplemental Indenture thereto, dated as of December
31, 2001 (the "FIRST SUPPLEMENTAL INDENTURE"), the Second Supplemental Indenture
thereto, dated as of December 17, 2002 (the "SECOND SUPPLEMENTAL INDENTURE"),
and the Third Supplemental Indenture thereto, dated as of April 3, 2003 (the
"THIRD SUPPLEMENTAL INDENTURE"). The Original Indenture, as supplemented by the
First Supplemental Indenture, the Second Supplemental Indenture and the Third
Supplemental Indenture, is referred to herein as the "INDENTURE."

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

                  Colorado.

         B.       I am a member of the bar of the State of Colorado.
