On the Closing Date, the Underwriters shall, at the direction of CIFSA, by wire transfer of immediately available funds, deposit or cause to be deposited the Escrow Amount into an escrow account titled “CIFSA Escrow Account for ev3 Acq” (the “Escrow Account”) established hereby with the Escrow Agent. The Escrow Amount plus any interest earned on the Escrow Amount, as provided in Section 5 hereof, from the Closing Date until the Escrow Amount is released from the Escrow Account pursuant to Section 6 hereof is referred to herein as the “Escrow Fund”.

2

(a) The Escrow Fund shall be held by the Escrow Agent and shall not be subject to any lien, attachment or any other judicial process of any creditor of any party hereto. The Escrow Agent agrees to accept delivery of the Escrow Amount and shall hold and safeguard the Escrow Fund and shall hold and dispose of the Escrow Fund only in accordance with the terms hereof.

(b) Upon receipt of the Escrow Amount into the Escrow Account, the Escrow Agent shall give notice of such receipt, in the form attached hereto as Exhibit A, to CIFSA and to the Representatives.

5. Investment of Escrow Fund.

(b) The Escrow Agent shall have the right to liquidate any investments held in the Escrow Fund in order to provide funds necessary to release the Escrow Fund pursuant to Section 6 hereof. The Escrow Agent in its capacity as escrow agent hereunder shall not have any liability for any

3

costs, fees, taxes or other expenses in connection with any investment hereunder or for loss sustained as a result of any liquidation of any investment prior to its maturity, if required pursuant to the preceding sentence, except for such losses resulting from the Escrow Agent’s gross negligence or willful misconduct.

(c) CIFSA agrees that, for tax reporting purposes, all interest and other income from investment of the Escrow Fund shall, as of the end of each calendar year and to the extent required by the Internal Revenue Service, be reported as having been earned by CIFSA. Prior to or at the time of execution of this Agreement, CIFSA shall provide the Escrow Agent with a certified tax identification number by furnishing an Internal Revenue Service Form W-8BEN. CIFSA understands that if such Form W-8BEN is not provided and certified to the Escrow Agent, the Escrow Agent may be required by the Internal Revenue Code of 1986, as amended, and the regulations promulgated thereunder, to withhold a portion of any interest or other income earned on the investment of the Escrow Fund. To the extent that the Escrow Agent becomes liable for the payment of any taxes in respect of income derived from the investment of the Escrow Fund, CIFSA hereby agrees to indemnify, defend and hold the Escrow Agent harmless from and against any tax, late payment, interest, penalty or other cost or expense that may be assessed against the Escrow Agent on or with respect to the Escrow Fund and the investment thereof unless such tax, late payment, interest, penalty or other expense was directly caused by the gross negligence or willful misconduct of the Escrow Agent or the grossly negligent failure of the Escrow Agent to timely deposit with the Internal Revenue Service any amounts the Escrow Agent withheld under this Section 5(c).

6. Release of Escrow Fund. The Escrow Agent shall release the Escrow Fund as follows:

(a) If the Escrow Agent receives, on or prior to the Redemption Trigger Time, a certificate in the form attached hereto as Exhibit B (the “Release Certificate”), executed by an Authorized Officer of CIFSA, the Escrow Agent shall release and deliver all amounts in the Escrow Fund in cash by 11:00 a.m. (New York City time) on the second business day after the date of the Release Certificate in accordance with the instructions set forth in the Release Certificate. The Escrow Agent shall confirm in writing to CIFSA that the Escrow Fund has been released by it in accordance with the Release Certificate.

(b) If (i) CIFSA delivers, and the Escrow Agent receives, at any time on or prior to the Redemption Trigger Time, a certificate in the form attached hereto as Exhibit C (the “Redemption Release Certificate”), executed by an Authorized Officer of CIFSA certifying that Covidien Group has determined to abandon the ev3 Acquisition prior to the Redemption Trigger Time or (ii) CIFSA has not delivered, and the Escrow Agent has not received, on or prior to the Redemption Trigger Time, the Release Certificate in accordance with paragraph

4

If the Escrow Agent receives the Redemption Release Certificate pursuant to clause (i) of this paragraph, the Escrow Agent shall confirm in writing to the Company that the amounts set forth in the Redemption Release Certificate have been released by it in cash in accordance with this Section 6(b).

(c) If CIFSA is required to effect the redemption contemplated by Section 1.4 of the Sixth Supplemental Indenture and for any reason the Escrow Fund is insufficient to pay the Special Redemption Price to redeem all of the outstanding Securities as provided in Section 1.4 of the Sixth Supplemental Indenture, CIFSA agrees to pay to the Paying Agent, on or prior to 11:00 a.m. (New York City time) on the Special Redemption Date, by wire transfer in immediately available funds additional cash in an amount that, together with the Escrow Fund, is sufficient to redeem all of the outstanding Securities on the Special Redemption Date at the Special Redemption Price in accordance with Section 1.4 of the Sixth Supplemental Indenture.

(d) If any funds remain in the Escrow Account after funds sufficient to pay for the redemption of the Securities on the Special Redemption Date have been released from the Escrow Account to the Paying Agent pursuant to paragraph (b) of this Section 6, then such remaining funds shall, on or prior to the close of business on the Special Redemption Date, or as soon thereafter as is practicable, be immediately released and delivered to CIFSA.

(e) If the Escrow Agent receives a written notice from the Trustee that the principal amount of, and accrued and unpaid interest on, the Securities has become immediately due and payable pursuant to Section 1.4 of the Sixth Supplemental Indenture, then the Escrow Agent shall release to the Paying Agent

(f) Any corporation or other entity into which the Escrow Agent in its individual capacity may be merged or converted or with which it may be consolidated, or any corporation or other entity resulting from any merger, conversion or consolidation to which the Escrow Agent in its individual capacity shall be a party, or any corporation or other entity to which all or substantially all the corporate trust business of the Escrow Agent in its individual capacity may be transferred, shall be the Escrow Agent under this Agreement without further act and such successor Escrow Agent shall be deemed to have assumed, without further act, all rights and obligations of the Escrow Agent hereunder.
