     Re: Caldera Corporation; Registration Statement on Form S-8

Gentlemen and Madam:

     I have been retained by Caldera Corporation (the "Company") in
connection with the registration statement (the "Registration Statement")
on Form S-8 to be filed by the Company with the Securities and Exchange
Commission relating to the securities of the Company.  You have requested
that I render my opinion as to whether or not the securities proposed to be
issued on the terms set forth in the Registration Statement will be validly
issued, fully paid, and nonassessable.

     In connection with this request, I have examined the following:

          1.   Articles of Incorporation of the Company, and amendments
               thereto;
          2.   Bylaws of the Company;
          3.   Unanimous consent resolutions of the Company's board of
               directors;
          4.   The Registration Statement; and
          5.   The Company's 1997 Non-Qualified Stock Option Plan, as
               amended.

     I have examined such other corporate records and documents and have
made such other examinations as I have deemed relevant.

     Based on the above examination, I am of the opinion that the
securities of the Company to be issued pursuant to the Registration
Statement are validly authorized and, when issued in accordance with the
terms set forth in the Registration Statement, will be validly issued,
fully paid, and nonassessable under corporate laws of the state of Florida.

     This opinion is limited in scope to the shares to be issued pursuant
to the Registration Statement and does not cover subsequent issuance of
shares to be made in the future.  Such transactions are required to be
included in either a new registration statement or a post-effective
amendment to the Registration Statement, including updated opinions
concerning the validity of issuance of such shares.

     Further, I consent to my name being included in the Registration
Statement as having rendered the foregoing opinion and as having
represented the Company in connection with the Registration Statement.

                                   Sincerely,

                                   /s/ Ronald N. Vance
