Exhibit 10.3 SECURITY AGREEMENT This SECURITY AGREEMENT (this "AGREEMENT") is dated as of December 5, 2001, by and between Gum Tech International, Inc., a Utah corporation ("GUM TECH") and Zensano, Inc., a California corporation ("ZENSANO"). Gum Tech and Zensano are sometimes referred to herein collectively as the "PARTIES" and each individually as a "PARTY". Capitalized terms used in this Agreement that are not expressly defined herein have the respective meanings given to them in the Purchase Agreement (as defined below). BACKGROUND Gum Tech, Zensano and Zensano's parent company, Zengen, Inc., a California corporation ("ZENGEN") are parties to that certain Purchase Agreement dated as of December 5, 2001 (the "PURCHASE AGREEMENT") pursuant to which Zensano has sold to Gum Tech, and Gum Tech has purchased from Zensano, effective as of the date hereof, Zensano's forty percent (40%) ownership interest (the "OWNERSHIP INTEREST") in Gel Tech, L.L.C., an Arizona limited liability company ("GEL TECH"). As partial consideration for its purchase of the Ownership Interest, Gum Tech has issued to Zensano a non-interest bearing promissory note dated as of the date of this Agreement in the original principal amount of Eleven Million Dollars ($11,000,000) (the "PROMISSORY NOTE") and has agreed to make certain other conditional payments under the Purchase Agreement. The Parties have agreed that Gum Tech's payment obligations under the Promissory Note and its conditional payment obligations under the Purchase Agreement will be secured by the Collateral (as defined herein), as more specifically provided by this Agreement. NOW THEREFORE THIS AGREEMENT WITNESSES that, in consideration of the mutual covenants and agreements contained herein, the receipt and sufficiency of which are hereby acknowledged, the Parties agree as follows: 1. GRANT OF SECURITY INTEREST. Gum Tech hereby grants to Zensano a first priority security interest (the "SECURITY INTEREST") in the Ownership Interest, all rights therein and thereunder and all proceeds thereof (collectively, the "COLLATERAL") as security for Gum Tech's obligations under the Promissory Note and Gum Tech's conditional payment obligations under Sections 2.2(b), 2.2(c), 2.5 and 2.7 of the Purchase Agreement. 2. DELIVERY OF CERTIFICATES. If at any time during the effectiveness of this Security Agreement, Gel Tech issues or causes to be issued any certificate or similar document evidencing the ownership by Gum Tech of the Ownership Interest, Gum Tech will promptly deliver such certificate or other document to Zensano together with a duly executed power of transfer with respect thereto (collectively, the "TRANSFER DOCUMENTS"), which documents Zensano will hold in trust pending the expiration or earlier termination of this Agreement or the exercise by Zensano of its rights under SECTION 7. Upon the expiration or earlier termination of this Agreement, if Zensano has not exercised its rights under SECTION 7, Zensano will promptly deliver the Transfer Documents to Gum Tech. 3. FINANCING STATEMENTS. Gum Tech will join in executing or will execute individually, as appropriate, all necessary financing statements and similar documents (collectively, "FINANCING STATEMENTS") reasonably required by, and prepared by, Zensano to perfect and protect the Security Interest granted hereunder. Filing for registration or recordation of any and all Financing Statements will be undertaken by Zensano at Zensano's sole cost. To the extent that such Financing Statements do not require any signatures by the Parties, Zensano is authorized to file or record such Financing Statements in the offices deemed appropriate by it. Zensano will promptly delivery to Gum Tech copies of all Financing Statements filed by Zensano in connection with this Agreement together with a list of each jurisdiction in which such Financing Statements are filed from time to time. 4. TERMINATION OF SECURITY INTEREST AND FINANCING STATEMENTS. The Security Interest will automatically terminate and be of no further force or effect immediately upon (i) full satisfaction by Gum Tech of its obligations under the Promissory Note, and (ii) full satisfaction or termination (as the case may be) of Gum Tech's conditional payment obligations under Sections 2.2(b), 2.2(c), 2.5 and 2.7 of the Purchase Agreement. Forthwith (and in any event within ten (10) Business Days) after full satisfaction and/or termination of Gum Tech's obligations under the Promissory Note and Sections 2.2(b), 2.2(c), 2.5 and 2.7 of the Purchase Agreement, Zensano will cause to be cancelled, discharged and released, at its sole cost, all Financing Statements and registrations or recordations thereof. If after the expiration of such ten (10) Business Days, Zensano, has failed to comply with its obligations under this SECTION 4, then effective as of such time, Zensano hereby irrevocably appoints Gum Tech as attorney and agent for, and in the name and on behalf of Zensano to prepare, execute, deliver and record to and with all applicable Persons all such agreements, instruments and documents as Gum Tech deems reasonably necessary or appropriate to properly discharge, cancel and release the registration or recordation of any and all Financing Statements made or filed by or on behalf of Zensano or any of its Affiliates in connection with this Agreement, and Zensano hereby ratifies and confirms all that Gum Tech may lawfully do or cause to be done by virtue of the appointment herein of Gum Tech as the attorney and agent for Zensano for the limited purposes described herein. All costs (including reasonable attorney's fees and expenses) incurred by Gum Tech acting in its capacity as the attorney and agent of Zensano for the limited purposes described herein will constitute a debt owed by Zensano to Gum Tech and will be due and payable immediately upon written demand therefor. 5. REPRESENTATIONS OF GUM TECH. Except to the extent that such representation is untrue, inaccurate or incomplete due to a misrepresentation or breach of warranty by Zengen or Zensano under the Purchase Agreement, (i) Gum Tech is the legal and equitable owner of the Ownership Interest, together with the other rights and interests comprising the Collateral described above, subject to no Encumbrances, and has full power and lawful authority to pledge, assign and grant a security interest in the Collateral hereunder, and (ii) there is no existing agreement, option, right or privilege capable of becoming an 2 agreement or option pursuant to which Gum Tech could be required to sell or otherwise dispose of all or a part of the Ownership Interest.

COVENANTS OF GUM TECH. Gum Tech hereby covenants and agrees that during the effectiveness of this Agreement, it will: (a) perform and comply, in all material respects, with all obligations and conditions on its part to be performed hereunder and under the Promissory Note; (b) defend its title to the Collateral and the interest of Zensano in the Collateral pledged hereunder against the claims and demands of all Persons; (c) not, without Zensano's prior written consent, directly or indirectly create, incur, assume or suffer to exist any Encumbrance on or with respect to any part of the Collateral that ranks higher in priority to the Security Interest, and Gum Tech will, at its own cost and expense, promptly take such action as may be necessary to discharge any such Encumbrance; PROVIDED, however, that this SECTION 6(C) will not apply to any Encumbrance on the Collateral that existed on or before the date hereof based on any act or omission of Zensano, Zengen or any Affiliate thereof; (d) keep accurate and complete records of the Collateral and, upon reasonable prior notice, will permit representatives of Zensano during normal business hours of Gum Tech to inspect Gel Tech's Articles of Organization, as amended, Operating Agreement and other company documents directly pertaining to the Collateral.

Zensano will give Gum Tech reasonable notice of the time and place of any public sale of the Collateral, or of the date upon which any private sale or any other intended disposition of Collateral is to be made. Notice by Zensano of any intended private sale will include a right offered to Gum Tech to bid on and purchase the Collateral for a price greater than that negotiated in such private sale.

LIMITATION ON EXERCISE OF REMEDIES. The Parties acknowledge and agree that Zensano will not be entitled to exercise its rights and remedies under SECTION 7 if Gum Tech does not pay any amount or delays in the payment of any amount under the Promissory Note or under any of Sections 2.2(b), 2.2(c), 2.5 or 2.7 of the Purchase Agreement where such non-payment or delay of payment is based on any claim for set-off made reasonably and in good faith by Gum Tech pursuant to the provisions of Section 6.10 of the Purchase Agreement, even if such set-off claim or the amount thereof is ultimately rejected or reduced under 4 the procedures established in Section 6.10 of the Purchase Agreement for the resolution of any such set-off claim. Zensano may not initiate or proceed with any collection, foreclosure or other actions under this Agreement until such set-off claim of Gum Tech has been disposed of pursuant to the provisions of Section 6.10 of the Purchase Agreement, and then only for amounts owing by Gum Tech under the Promissory Note or under any of Sections 2.2(b), 2.2(c), 2.5 or 2.7 of the Purchase Agreement from the date of such disposition. 9.
