ITEM 1.01  ENTRY INTO A MATERIAL DEFINITIVE AGREEMENT.

On December 7, 2004, Medical Discoveries, Inc. (the "Company") entered into a
Registration Rights Agreement dated December 3, 2004 among Mercator Momentum
Fund, LP; Mercator Momentum Fund III, LP; Mercator Advisory Group, LLC; and the
Company. The Registration Rights Agreement was entered into in connection with
the contingent sale by the Company of 30,000 shares of Series A Convertible
Preferred Stock (the "Preferred Stock") of the Company and warrants to purchase
22,877,478 shares of common stock of the Company to Mercator Momentum Fund, LP;
Mercator Momentum Fund III, LP and Mercator Advisory Group, LLC. The
Registration Rights Agreement requires the Company to file a registration
statement with the Securities and Exchange Commission (the "SEC") registering
the shares of common stock issuable upon conversion of the Preferred Stock and
exercise of the warrants. The registration statement must be filed by December
15, 2004, and the registration statement must be declared effective by the SEC
no later than 90 days after it is filed. A copy of the Registration Rights
Agreement is attached to this report as Exhibit 4.1.

ITEM 3.02  UNREGISTERED SALES OF EQUITY SECURITIES.

The Company has sold the following unregistered securities since October 17,
2004. None of the sales involved an underwriter. The Company believes these
sales were exempt from registration pursuant to Section 4(2) of the Securities
Act of 1933 because the sales did not involve a public offering.

        On or about December 7, 2004, the Company entered into a contingent
        agreement to sell 30,000 shares of its Preferred Stock and warrants to
        purchase 22,877,478 shares of common stock of the Company for a total
        offering price of $3 million. Each share of Preferred Stock entitles the
        holder to convert the share of Preferred Stock into the number of shares
        of common stock resulting from multiplying $100 by the conversion price.
        The conversion price is 75% of the average of the lowest three intra-day
        trading prices for the Company's common stock during the 10 trading days
        immediately preceding the conversion date, but the conversion price may
        not exceed $0.1967. The number of shares of common stock subject to the
        warrants and the exercise price are subject to equitable adjustment in
        connection with a stock split, stock dividend or similar transaction.
        The warrants entitle the holder to purchase up to 22,877,478 shares of
        common stock of the Company on or before the third anniversary of the
        issuance date of the warrants at $0.1967 per share. The number of shares
        of common stock subject to the warrants and the exercise price are
        subject to equitable adjustment in connection with a stock split, stock
        dividend or similar transaction.

        The sale is contingent upon the Company entering into and closing a
        definitive agreement to purchase certain assets in a proposed
        acquisition, the details of which have not yet been disclosed and
        regarding which no definitive agreement is yet executed.
