The Exercise Price may be paid in the form of a check or wire transfer of immediately available funds.

4. Effective Date of Exercise. Each exercise of this Warrant shall be deemed effective as of the close of business on the day on which this Warrant is surrendered to the Company as provided in Section 3 above.

5. Protection Against Dilution.

(a) Adjustment for Stock Splits, Dividends and Combinations. If the Company, at any time after the date of this Warrant, subdivides, declares a dividend payable in, or combines the outstanding shares of Series D Preferred Stock then (i) the number of shares of Series D Preferred Stock for which this Warrant may be exercised as of immediately prior to the subdivision, combination or record date for such dividend payable in Series D Preferred Stock shall forthwith be proportionately decreased, in the case of combination, or increased, in the case of subdivision or dividend payable in Series D Preferred Stock, and (ii) the Exercise Price in effect immediately prior to the subdivision, combination or record date for such dividend payable in Series D Preferred Stock shall forthwith be proportionately increased, in the case of combination, or decreased, in the case of subdivision or dividend payable in Series D Preferred Stock.

-2-

The adjustment shall be made successively whenever any such distribution is made and shall become effective immediately after the record date for the determination of stockholders entitled to receive the distribution. Upon each adjustment of the Exercise Price, the Holder shall be entitled to purchase, at the Exercise Price resulting from such adjustment, the number of shares that is equal to the quotient of (i) the Exercise Price immediately prior to such adjustment multiplied by the number of shares purchasable pursuant hereto immediately prior to such adjustment; divided by (ii) the Exercise Price.

(c) Adjustment for Reorganizations, Mergers, Etc. If any capital reorganization or reclassification of the capital stock of the Company, or share exchange, combination, consolidation or merger of the Company with another corporation, or the sale of all or substantially all of its assets to another corporation shall be effected in such a way that holders of Series D Preferred Stock shall be entitled to receive stock, securities or assets with respect to or in exchange for Series D Preferred Stock, then, as a condition of such reorganization, reclassification, share exchange, combination, consolidation, merger or sale, lawful and adequate provision shall be made whereby the Holder shall thereafter have the right to receive upon exercise of this Warrant, upon the basis and upon the terms and conditions specified in this Warrant and in lieu of the shares of the Series D Preferred Stock of the Company into which this Warrant could be exercisable, such shares of stock, securities or assets as may be issued or payable with respect to or in exchange for a number of outstanding shares of such Series D Preferred Stock equal to the maximum number of shares of such stock issuable upon exercise of this Warrant, and in any such case appropriate provisions shall be made with respect to the rights and interests of Holder to the end that the provisions hereof (including without limitation provisions for adjustments of the Exercise Price and of the number

-3-

of shares purchasable upon exercise of this Warrant) shall thereafter be applicable, as nearly as may be, in relation to any shares of stock, securities or assets thereafter deliverable upon the exercise hereof. The Company shall not effect any such share exchange, combination, consolidation, merger or sale, unless prior to the consummation thereof the successor corporation (if other than the Company) resulting from such share exchange, combination, consolidation or merger or the corporation purchasing such assets shall assume by written instrument executed and mailed to the Holder, at the last address of such Holder appearing on the books of the Company, the obligation to deliver to such Holder such shares of stock, securities or assets that, in accordance with the foregoing provisions, such Holder may thereafter be entitled to receive upon exercise of this Warrant.

(d) Successive Adjustments and Notice. The above provisions of this Section 5 shall similarly apply to successive stock splits, combinations, dividends, reorganizations, reclassifications, consolidations, mergers or sales. The Company shall deliver written notice of each such event, and of each such adjustment to the Exercise Price resulting from such proposed event, to the Holder not less than twenty (20) days prior to such event. If any event occurs of the type contemplated by the adjustment provisions herein, but which is not expressly provided for by such provisions, the Company will deliver notice of such event as provided above and the Company will make an appropriate adjustment in the Exercise Price and the number and type of shares acquirable upon exercise of this Warrant so that the rights of the Holder shall be neither enhanced nor diminished as a result of such event.

(e) Issuance of Convertible Securities. If the Company in any manner issues or sells any options, warrants or rights to subscribe for or to purchase Series D Preferred Stock, or securities convertible into shares of Series D Preferred Stock (such options, warrants, rights or securities being herein called “Series D Convertible Securities”), the Company shall be deemed to have issued the maximum number of shares of Series D Preferred Stock issuable upon the exercise or conversion of such Series D Convertible Securities for consideration equal to the amount of consideration, if any, received by the Company upon issuance of such Series D Convertible Securities plus the minimum aggregate amount of consideration payable to the Company upon exercise or conversion of such Series D Convertible Securities.

(f) Price Protection. If the Company issues or sells, or is deemed to have issued or sold, Series D Preferred Stock for consideration per share less than the Exercise Price in effect at the time of such issuance, then effective immediately upon such issuance the Exercise Price shall be reduced to equal the amount of such consideration per share. Notwithstanding the foregoing, the adjustment provided for in this Section 5(f) shall not apply to the issuance of Company capital stock upon exercise of options granted prior to the date hereof pursuant to employee benefit plans approved by the Company’s Board of Directors.

6. No Voting Rights. This Warrant shall not entitle the Holder to any voting rights or other rights as a shareholder of the Company unless and until exercised pursuant to the provisions hereof.

7. Transfer or Exchange without Registration. In the event the Holder desires to transfer this Warrant, the Holder shall provide the Company written notice describing the manner of such transfer and an opinion of counsel that the proposed transfer may be effected without registration under the Securities Act or applicable state securities registration laws, whereupon the Holder shall be

-4-

entitled to transfer this Warrant in accordance with such notice. Upon receipt of evidence reasonably satisfactory to the Company of the loss, theft, destruction or mutilation of this Warrant and, in the case of any such loss, theft, or destruction, upon delivery of an indemnity agreement reasonably satisfactory in form an amount to the Company, or, in the case of any such mutilation, upon surrender of this Warrant, the Company, at its expense, will execute and deliver, in lieu thereof, a new Warrant of like tenor.

Notwithstanding anything herein to the contrary, this Warrant may not be transferred by the Holder hereof except to a direct or indirect subsidiary of Medtronic, Inc., a Minnesota corporation (which shall specifically exclude the Medtronic Foundation). Further, the Holder, by acceptance hereof, agrees not to sell or transfer any Warrant Shares (or the shares of Common Stock issuable upon conversion thereof) for at least thirty-two (32) days after the exercise of this Warrant which resulted in the issuance of such Warrant Shares.
