Technologies to ASC and the issuance of MDI common stock to the Harvest Group.

relationship which will allow for development and execution of a business plan
to fund the marketing and commercialization of the Technologies on the terms and
conditions set forth in this Agreement Such business structure and relationship

        1.2 Assignment and Transfer of the Technologies. At the Closing, MDI and
HCS will assign and transfer to ASC, all of their respective rights and title in
and to the Technologies. The Technologies are specifically described and listed
on Schedule 1.2 attached hereto and by this reference made a part hereof. The
Technologies specifically include MDI-P and underlying patents and technologies
as they apply to cosmeceuticals and skin care products and excludes MDI-P as it
applies to pharmaceutical applications. In exchange for MDI's assignment and
transfer of the Technologies to ASC, at Closing, ASC shall issue to MDI
2,000,000 ASC Shares. ASC will use its best efforts to employ the capital
contributed to ASC contemplated in this agreement for commercialization of the
Technologies.

Closing, free and clear of all liens, security interests, charges, encumbrances
and rights of others (each, an "Encumbrance") other than the "Permitted
Encumbrances".

Agreement to the contrary, ASC shall assume those liabilities (the "Assumed
Liabilities") of MDI, which are specifically identified on Schedule 1.3 attached
hereto. The Assumed Liabilities shall be "Permitted Encumbrances" on the
Technologies. ASC may, if it deems such action prudent, contest the validity of
any Permitted Encumbrances. Except for the Assumed Liabilities, the Purchaser
has not agreed to pay, shall not be required to assume and shall have no
liability or obligation with respect to any debt, obligation, responsibility or
liability of MDI, any Affiliate or successor of MDI, or any claim against any of
the foregoing, whether known or unknown, contingent or absolute, or otherwise
(the "Excluded Liabilities"). MDI agrees to take all actions and do all things
reasonably necessary to ensure that ASC is not liable for any Excluded
Liabilities.

the Agreement, or breach thereof (hereinafter collectively referred to as a
"Dispute"). In the event such negotiations fail, the Dispute shall first be
submitted for initial fact-finding mediation to a neutral third party reasonably
acceptable to both the Sellers, on the one hand, and the Purchaser, on the
other, in Utah or at such other place as the parties mutually agree. Such
mediator shall be selected within thirty (30) days of written notice by either
party to the other demanding such fact-finding mediation.

        a)  In the event that the Parties cannot resolve the Dispute within
            sixty (60) days of the initial demand for such fact-finding
            mediation, each of the Parties reserve the right to demand, within
            30 days thereafter, that the Dispute be submitted to arbitration.
            Any party may initiate an arbitration proceeding by a request in
            writing submitted to the other party. Thereupon, the Dispute shall
            be settled by arbitration in accordance with the American

            one of which shall be selected by the Harvest Group, one by MDI, and
            the third by the arbitrators selected by the parties (the
            "Arbitrators"). The arbitration shall be governed by the Commercial
            Arbitration Rules of the American Arbitration Association. The award
            rendered by the Arbitrators shall be final and enforcement upon the
            award may be entered by any court having jurisdiction thereof. The
            arbitration shall be conducted in Salt Lake City, Utah or at such
            other place as the Parties mutually agree. The Arbitrators shall
            award reasonable attorney's fees to the prevailing party. Subject to
            the foregoing, the costs of such fact-finding mediation and/or
            arbitration shall be borne equally by the Harvest Group and MDI.
            Notwithstanding anything in this Section 8.10 to the contrary,
            either party may seek injunctive relief to enforce any
            non-competition or confidentiality obligations of the other party.
            NOTWITHSTANDING THE FOREGOING, THE DISPUTE RESOLUTIONS SET FORTH
            HEREIN ARE EXPRESSLY SUBJECT TO THE PROVISIONS OF THE CODE.
