ARTICLE I.

CONTRIBUTION AND EXCHANGE

Section 1.1. Contribution of MTI Common Stock. On the basis of the representations, warranties and agreements contained herein, and subject to the terms and conditions hereof, including, without limitation, the satisfaction (or waiver, to the extent permitted by this Agreement and applicable law) of the conditions set forth in Article VII of this Agreement, effective at the Closing each of the Stockholders hereby agrees to contribute, transfer, assign and convey to ev3 LLC all right, title and interest in and to all of the shares of MTI Common Stock owned directly by such Stockholder, which MTI Shares are set forth opposite such Stockholder’s name on Schedule II hereto, together with any and all rights, privileges, benefits, obligations and liabilities appertaining thereto, reserving unto such Stockholder no rights or interests therein whatsoever, to have and to hold the same unto ev3 LLC and its heirs, legal representatives, successors and assigns, from and after the Closing to its own proper use forever.

Section 1.2. Acceptance of Contribution. On the basis of the representations, warranties and agreements contained herein, and subject to the terms and conditions hereof, effective at the Closing ev3 LLC hereby agrees to accept the Contribution of the MTI Common Stock pursuant to Section 1.1.

Section 1.3. Exchange. In consideration of the Contribution by the Stockholders and on the basis of the representations, warranties and agreements contained herein, and subject to the terms and conditions hereof, on the Closing Date and in exchange for the MTI Shares contributed to ev3 LLC pursuant to Section 1.1, ev3 LLC shall issue and deliver to each Stockholder the number of Common Membership Units determined by dividing (i) the product obtained by multiplying (A) the number of shares of MTI Common Stock owned directly by such Stockholder (as set forth opposite the respective Stockholder’s name on Schedule II hereto) by (B) the quotient obtained by dividing (1) the sum of the daily closing prices per share of MTI Common Stock as quoted on the NASDAQ National Market (symbol “MTIX”) and reported in The Wall Street Journal (Northeast Edition), absent manifest error, for the twenty (20) consecutive trading days from and including the date the Registration Statement is first filed by the Company with the SEC by (2) twenty (20), by (ii) the per share Split-Adjusted Midpoint (as defined below). In the event the daily closing price per share of MTI Common Stock as quoted on the NASDAQ National Market differs from the daily closing price reported in The Wall Street Journal (Northeast Edition), the daily closing price per share of MTI Common Stock as quoted on the NASDAQ National Market shall control. The “Split-Adjusted Midpoint” shall equal the quotient obtained by dividing (i) the midpoint of the range of estimated initial public offering prices as set forth on the cover of the Preliminary Prospectus by (ii) the number of shares of Company Common Stock necessary to obtain one share of Company Common Stock in connection with the reverse split to be declared with respect to Company Common Stock that is to take effect prior to the consummation of the Initial Public Offering (the “Reverse Split”). For example, if the Preliminary Prospectus states that the Company will effect a 1 for 5 Reverse Split, clause (ii) of the definition of Split-Adjusted Midpoint shall equal 5.

Section 1.4. No Fractional Units Notwithstanding anything to the contrary contained herein, no certificates or scrip representing fractional Common Membership Units shall be issued to any Stockholder in connection with the Exchange. Instead, any fractional Common Membership Units that a Stockholder would otherwise be entitled to receive as a result of the Exchange shall be rounded up to the nearest whole number of Common Membership Units.

Section 1.5. Power of Attorney. From and after the Closing Date, each Stockholder constitutes and appoints ev3 LLC, its successors and assigns, as the Stockholder’s true and lawful attorney-in-fact, with full power of substitution, in the name of ev3 LLC or in the name of the Stockholder, to execute, deliver, file and/or record such documents, agreements and instruments as shall be necessary or appropriate to effect the Contributions pursuant to this Article I. The foregoing powers are coupled with an interest and shall be irrevocable.

Section 1.6. Characterization. The Contribution, the transactions described in the Merger Agreement and the Note Contribution Agreement and the public’s purchase of stock in the Initial Public Offering are part of an integrated plan and are intended together to qualify as a tax-free transaction under Section 351 of the Internal Revenue Code of 1986, as amended.

Neither the execution and delivery of this Agreement nor the consummation of the transactions contemplated hereby nor compliance with any of the provisions hereof will (a) result in any conflict with, breach of, or default (or give rise to any right of termination, cancellation or acceleration) under any of the terms, conditions or provisions of any agreement or other instrument or obligation to which such Stockholder is a party or by which such Stockholder or any of such Stockholder’s properties or assets may be bound or (b) violate any order, writ, injunction, judgment, decree, law, statute, rule or regulation applicable to such Stockholder or any of such Stockholder’s properties or assets.

-5-

exemption from such qualification or registration is available, and that ev3 LLC has no present intention of so registering the Common Membership Units.

The Stockholder acknowledges that at the present time Rule 144 promulgated under the Securities Act by the SEC (“Rule 144”) is not applicable to sales of the Common Membership Units because such units are not registered under Section 12 of the Exchange Act, and there is not publicly available the information concerning ev3 LLC specified in Rule 144.
