        Re:     Shelf Registration Statement on Form S-3 Relating 
                to 2,864,225 Shares of Common Stock                

Ladies and Gentlemen:

   
        We have acted as counsel for HS Resources, Inc., a Delaware corporation
(the "Company"), in connection with the preparation of a Registration Statement
on Form S-3 (the "Registration Statement") filed by the Company with the
Securities and Exchange Commission.  The Registration Statement relates to the
registration under the Securities Act of 1933, as amended (the "1933 Act"), of
2,864,225 shares of the Company's common stock, par value $.001 per share (the
"Shares"), offered for the account of a certain stockholder of the Company.
    

        This opinion is delivered pursuant to the requirements of Item
601(b)(5) of Regulation S-K under the 1933 Act.

        We have examined certain documents, corporate records and other
instruments and relied on originals or copies, certified or otherwise
identified to our satisfaction, of such documents, corporate records and other
instruments, have made such inquiries as to questions of fact of officers and
representatives of the Company, and have made such examinations of law as we
have deemed necessary or appropriate for purposes of giving the opinion
expressed below.  In such examination, we have assumed the genuineness of all
signatures, the authenticity of all documents submitted to us as originals and
the conformity with the originals of all documents submitted to us as copies.
