_______SERIES B WARRANTS ("Warrants") entitling the holder to acquire, subject to adjustment, one share of common stock for every one Warrant represented hereby

ORAGENICS, INC.

INCORPORATED UNDER THE LAWS OF THE STATE OF FLORIDA

THIS IS TO CERTIFY THAT *_____________ (hereinafter referred to as the "holder") is the registered holder of the number of Warrants to purchase shares of common stock ("Common Shares") of Oragenics, Inc. (the "Company") as set forth in this Series B Warrant certificate ("Warrant Certificate"). Each Warrant represented hereby entitles the holder thereof to acquire one fully paid and non-assessable Common Share in the capital of the Company without par value, as such shares were constituted on , 2002 (a "Warrant Share") in the manner and subject to the restrictions and adjustments set forth herein at any time and from time to time until 4:30 p.m. (Vancouver time) (the "Time of Expiry") on , 200 (the "Expiry Date"), at a price of US$3.00.

The right to acquire Warrant Shares hereunder may only be exercised by the holder within the time set forth above by duly completing and executing the Exercise Form attached hereto by surrendering this Warrant Certificate to Computershare Trust Company of Canada (the "Trustee") at the principal office of the Trustee in the City of Vancouver and remitting a certified cheque, bank draft or money order in lawful money of the United States payable to the order of the Company at par where this Warrant Certificate is so surrendered for the aggregate purchase price of the Warrant Shares so subscribed for.

These Warrants shall be deemed to be surrendered only upon personal delivery hereof or, if sent by mail or other means of transmission, upon actual receipt thereof by the Trustee at the office referred to above.

Upon surrender of these Warrants, the person or persons in whose name or names the Warrant Shares issuable upon exercise of the Warrants are to be issued shall be deemed for all purposes (except as provided in the Indenture hereinafter referred to) to be the holder or holders of record of such Warrant Shares and the Company has covenanted that it will (subject to the provisions of the Indenture) cause a certificate or certificates representing such Warrant Shares to be delivered or mailed to the person or persons at the address or addresses specified in the Exercise Form within five Business Days.

 


If, at the time of exercise by the Warrantholder of any of the Warrants represented by this Warrant Certificate, the registration statement filed by the Company under the United States Securities Act of 1933 (the "1933 Act") on ______ is no longer effective, then this Warrant may not be exercised in the United States or by or on behalf of a U.S. person, as such terms are defined in Regulation S under the 1933 Act, unless the Warrantholder has delivered to the Company a written opinion of counsel to the effect that the exercise of the Warrant and the Warrant Shares to be delivered upon exercise hereof have been registered under the 1933 Act or an available exemption from the registration requirements thereunder.

The registered holder of this Series B Warrant Certificate may acquire any lesser number of Warrant Shares than the number of Warrant Shares which may be acquired for the Warrants represented by this Warrant Certificate. In such event, the holder shall be entitled to receive a new certificate for the balance of the Warrant Shares which may be acquired. No fractional Warrant Shares will be issued.

The Warrants represented by this Warrant Certificate are issued under and pursuant to a Warrant indenture (the "Indenture") made as of , 2002 between the Company and the Trustee. Reference is made to the Indenture and any instrument supplemental thereto for a full description of the rights of the holders of the Warrants and the terms and conditions upon which the Warrants are, or are to be issued and held, with the same effect as if the provisions of the Indenture and all instruments supplemental thereto were set forth herein. By acceptance hereof, the holder assents to all provisions of the Indenture. In the event of a conflict between the provisions of the Warrant Certificate and the Indenture, the provisions of the Indenture shall govern. Capitalized terms used in the Indenture have the same meaning herein as therein unless otherwise defined.

In the event of any alteration of the Common Shares, including any subdivision, consolidation or reclassification, and in the event of any form of reorganization of the Company including any amalgamation, merger or arrangement, the holders of Warrants shall, upon exercise of the Warrants following the occurrence of any of those events, be entitled to receive the same number and kind of securities that they would have been entitled to receive had they exercised their Warrants immediately prior to the occurrence of those events.

The registered holder of this Warrant Certificate may at any time prior to the Expiry Date upon surrender hereof to the Trustee at its principal office in the City of Vancouver, exchange this Warrant Certificate for other certificates entitling the holder to acquire in the aggregate the same number of Warrant Shares as may be acquired under this Warrant Certificate.

The holding of the Warrants evidenced by this Warrant Certificate shall not constitute the holder hereof a shareholder of the Company or entitle the holder to any right or interest in respect thereof except as expressly provided in the Indenture or in this Warrant Certificate.

The Indenture provides that all holders of Warrants shall be bound by any resolution passed at a meeting of the holders held in accordance with the provisions of the Indenture and resolutions signed by the holders of Warrants entitled to acquire a specified majority of the Warrant Shares which may be acquired pursuant to all the outstanding Warrants.

This Warrant Certificate shall not be valid for any purpose whatsoever unless and until it has been certified by or on behalf of the Trustee.

Time shall be of the essence hereof. This Warrant Certificate shall be governed by and construed in accordance with the laws of the Province of British Columbia and the federal laws applicable therein and shall be treated in all respects as a British Columbia contract.
