SOURCE AND AMOUNT OF FUNDS OR OTHER CONSIDERATION This statement relates to an Investment Agreement entered into on May 22, 2001 (the "Investment Agreement") between AVI and MAMI. Pursuant to the Investment Agreement, on June 20, 2001, MAMI purchased 1,408,451 shares of AVI Common Stock at a price of $7.10 per share and received a warrant to purchase an additional 3,000,000 shares of AVI Common Stock (the "Warrant") exercisable at a price of $10.00 per share at any time during the five years after June 20, 2001. The Investment Agreement contemplates additional purchases by MAMI of up to $10,000,000 of AVI Common Stock subject to the achievement of certain milestones and the receipt of certain governmental and regulatory approvals. Funds for the purchase of such shares, including any shares purchased upon exercise of the Warrant, have been and will be provided out of the working capital of MAMI following a capital contribution in like amount made by Medtronic, which owns all the issued and outstanding shares of MAMI. Item 4. PURPOSE OF TRANSACTION MAMI has acquired the shares of AVI Common Stock and the Warrant solely for investment purposes. Based upon its evaluation of AVI's financial condition, market conditions and other factors it may deem material, the reporting persons may seek to acquire additional shares of AVI Common Stock in the open market or in private transactions, or may dispose of all or any portion of the shares currently owned or which may be acquired upon exercise of the Warrant. Except as set forth in the preceding sentence or as provided in the Investment Agreement, the reporting persons presently do not have any definitive plans or proposals that relate to or would result in transactions of the kind described in paragraphs (a) through (j) of Item 4 of Schedule 13D, but may, at any time and from time to time, review, reconsider and discuss with AVI or others the reporting persons' positions with respect to AVI which could thereafter result in the adoption of such plans or proposals. At the time of MAMI's acquisition of the shares of AVI Common Stock and the Warrant, AVI and Medtronic entered into a License and Development Agreement (the "License Agreement") and a Supply Agreement (the "Supply Agreement"). Under the License Agreement, AVI granted to Medtronic a worldwide exclusive license for a family of antisense compounds, including Resten-NG(TM), which Mectronic expects to load on medical devices, including stents to treat vascular disease. Under the Supply Agreement, AVI agreed to supply all of Medtronic's needs for the products developed by Medtronic under the License Agreement at negotiated prices. 6 Item 5. INTEREST IN SECURITIES OF THE ISSUER (a) Medtronic, through MAMI, is the beneficial owner of 4,408,451 shares of Common Stock of AVI (including 3,000,000 shares which are not outstanding but which may be purchased upon exercise of the Warrant), which represents approximately 17.0% of the outstanding Common Stock of AVI (assuming exercise of the Warrant). To the knowledge of the reporting persons, no other person named in Item 2 beneficially owns any AVI shares. (b) Medtronic, through MAMI, has the sole power to vote and the sole power to dispose of all shares of AVI Common Stock beneficially owned by it. (c) The only transaction in the Common Stock of AVI that was effected by any person named in paragraph (a) above during the past 60 days is the acquisition of 1,408,451 shares and a Warrant to purchase 3,000,000 shares as reported in Item 3 above. (d) No other person is known to have the right to receive or the power to direct the receipt of dividends from, or the proceeds of the sale of, the subject securities. (e) Not applicable. Item 6. CONTRACTS, ARRANGEMENTS, UNDERSTANDINGS OR RELATIONSHIPS WITH RESPECT TO SECURITIES OF THE ISSUER As described in Item 3 above, MAMI is a party to the Investment Agreement pursuant to which MAMI acquired 1,408,451 shares of AVI Common Stock and a Warrant to purchase 3,000,000 shares and may acquire additional shares upon the happening of certain events. AVI and MAMI also entered into a registration rights agreement which grants to MAMI and its transferees or assignees certain demand and piggyback registration rights regarding the registration for resale of (a) the AVI Common Stock acquired or to be acquired by MAMI pursuant to the Investment Agreement, (b) the Warrant and (c) the shares of AVI Common Stock which may be acquired upon exercise of the Warrant.
