Item 1.01         Entry into a Material Definitive Agreement.

                  On June 16, 2005, the Company entered into a consulting
                  agreement with an effective date of June 1, 2005, between
                  the Company and Ronald W. Davis (the "Consulting
                  Agreement"). Immediately prior to the effectiveness of the
                  Consulting Agreement, Mr. Davis was employed by the
                  Company as its President, Business Development.

                  Consulting Agreement
                  --------------------

                  Pursuant to the terms of the Consulting Agreement, Mr.
                  Davis will provide consulting and advisory services
                  pertaining to the business and operations of the Company.
                  He will assist with the transition of the successor
                  President, Business Development and shall perform such
                  other duties and responsibilities as may be requested by
                  the Company's Chief Executive Officer and Board of
                  Directors.

                  The initial term of the Consulting Agreement commenced
                  June 1, 2005 and continues through May 31, 2006 (the
                  "Initial Term"). Thereafter, the Consulting Agreement
                  automatically renews for successive one year periods
                  unless terminated by either party upon written notice at
                  least 30 days prior to the expiration of the Initial Term
                  or any renewal term, as the case may be. The Consulting
                  Agreement terminates prior to the expiration of the
                  Initial Term or a renewal term upon the death or
                  disability of Mr. Davis. Mr. Davis also may terminate the
                  Agreement upon at least 30 days notice to the Company. The
                  Company may terminate the Agreement at any time with or
                  without cause.

                  Mr. Davis' consulting fee under the Consulting Agreement
                  is $210 per hour, or $1,680 per day when services are
                  performed for eight or more hours on a given day. The
                  Consulting Agreement provides that upon a termination by
                  the Company without cause, the Company will pay Mr. Davis
                  twelve consecutive monthly installments of $14,333.

                  In addition to the consulting fee, Mr. Davis is entitled
                  to: (a) reimbursement of reasonable and necessary expenses
                  incurred in the interest of the business of the Company;
                  (b) a car allowance of not less than $1,000 per month;
                  and (c) participation in the Company's medical and dental
                  insurance programs along with his spouse for the duration
                  of his life and the life of his spouse on the same basis
                  as executives of the Company who are entitled to
                  participate in the same.

                  The Consulting Agreement also contains non-compete and
                  non-diversion covenants that extend for so long as the
                  Consulting Agreement is in effect and for a two year
                  period after termination of the Consulting Agreement.

                  The description of the Consulting Agreement is qualified
                  in its entirety by reference to the complete agreement
                  that is attached as Exhibit 10.1 hereto and is
                  incorporated herein by reference.
