         RE:      Issuance of Stock Pursuant to S-8 Registration Statement

Gentlemen:

         Pursuant to your request, we have examined the S-8 Registration
Statement to be filed with the Securities and Exchange Commission, registering
300,000 shares of common stock in the company. We have further examined the
Certificate of Incorporation, Articles of Incorporation, Bylaws, any amendments
thereto, and all such corporate records and documents that we believed were
necessary or relevant to enable us to render an opinion in this matter.

         Based solely on the foregoing examination, it is our opinion that, when
sold and issued according the 2003 Stock for Consultants Plan, the shares of
common stock covered by the Registration Statement will be legally issued, fully
paid, and non assessable.

         We consent to the filing of this opinion as an exhibit to the
Registration Statement.

                                          Very truly yours,

                                          SANDERSBAKER PC



                                          Edward L. Morris
