(a)                                  Landlord and Tenant hereby approve the plans
for the expanded parking lot and related improvements (the “Parking
Improvements”) attached to this Amendment as Exhibit “A”
(the “Plans”). Landlord shall secure from the Contractor performing the Parking
Improvements for the benefit of the Landlord and the Tenant a warranty that the
Parking Improvements will be of good quality free from defects for a period of
I (one) year and suitable for the intended uses.

(b)                                 Subject to the issuance of all necessary
permits and approvals, Landlord shall complete the Parking Improvements, at Tenant’s
expense, in accordance with the Plans. The target completion date for the
Parking Improvements is November 30, 2005, subject to extension for delays due
to weather or any other cause beyond the reasonable control of Landlord or

(c)                                  Tenant shall be responsible for the aggregate
of all costs, expenses and fees incurred by or on behalf of Landlord in
connection with the Parking Improvements (the “Tenant’s Costs”), including
without limitation (i) architectural, engineering and design costs, (ii) all
other costs incurred in

connection with obtaining the necessary permits and
approvals, (iii) reasonable attorneys’ fees incurred in connection with the

receipt of each invoice from Landlord for Tenant’s Costs. At Tenant’s request,
Landlord shall provide Tenant copies of invoices, contracts or other reasonable
supporting documentation from its

Tenant agrees in writing to pay the excess. Landlord has no obligation to incur
costs and expenses in excess of the Cap absent such written agreement by Tenant

because of soil conditions 

discovered during the course of construction or otherwise, Landlord shall so
notify Tenant and consult with Tenant regarding Tenant’s Costs. In such event
Landlord shall have no obligation to continue with the construction of the
Parking Improvements unless Tenant agrees in writing to cover the Tenant’s
Costs in excess of the Cap. Absent such agreement, Landlord shall have the
right to cease construction, and in such event Tenant shall reimburse Landlord
for all Tenant’s Costs incurred by Landlord through that date, together with
all additional out-of- pocket costs and expenses reasonably incurred by
Landlord in connection with the cessation of the project and any restoration
work Landlord reasonably deems necessary or advisable.

2.                                       Exclusive Use.  Tenant
shall have the exclusive use, for parking purposes, of the expansion parking
area constructed pursuant to this Amendment for the Lease Term. Landlord shall
not permit any other tenant or party to park in the parking area expanded
pursuant to this Amendment for the Lease Term.

3.                                       Operating Expenses. 
Section 1(c) of the Lease notwithstanding, Tenant shall he responsible
for 100% of the Annual Operating Expenses related to the expansion parking
area.

4.                                       Defined Terms.  All
capitalized terms used in this Amendment not separately defined herein shall
have the meaning given them in the Lease.

5.                                       Full Force and Effect.  All
of the terms and conditions of the Lease not inconsistent with this Amendment
shall remain unmodified and in full force and effect.

6.                                       Counterparts. This Amendment may be executed in
counterparts and may be delivered by facsimile transmittal of signed original
counterparts.

SECOND
AMENDMENT TO LEASE

THIS AMENDMENT (“Amendment”)
is made effective as of the 1st day of October, 2005, by and between LIBERTY PROPERTY LIMITED PARTNERSHIP, a
Pennsylvania limited partnership (hereinafter called “Landlord”), and ev3 INC., a Delaware corporation
(hereinafter called “Tenant”).

BACKGROUND:

A.                                   Landlord and Tenant are parties to that
certain Lease dated as of May 3, 2002 (together with all amendments thereto,
the “Lease”) for certain premises containing approximately 63,891 rentable
square feet in the Building known as Nathan Lane Technology Center and having
an address of 4600 Nathan Lane, Plymouth, Minnesota.

B.                                     Tenant has requested an additional allowance
for leasehold improvements and Landlord has agreed to provide the allowance on
the terms and conditions set forth in this Amendment.

AMENDMENT:

Now therefore, for good and
valuable consideration, the receipt and legal sufficiency of which the parties
acknowledge, the parties agree as follows:

I.                                         Allowance.  Landlord
shall provide Tenant with an additional leasehold improvement allowance of up
to $600,000 (the “Allowance”). The Allowance may only be used for leasehold
improvements in and to the Premises, which improvements shall be consistent in
quality and type with those leasehold improvements already in place. In no
event shall the Allowance be used for trade fixtures, equipment, furnishings or
other removable personal property of Tenant. Any leasehold improvements
constructed by Tenant in the Premises shall be constructed pursuant to plans
and specifications approved by Landlord and by a general contractor approved by
Landlord, which approval shall not be unreasonably withheld, conditioned or
delayed and shall otherwise be constructed in accordance with the provisions of
Sections 9 and 10 of the Lease. All construction shall be done at Tenant’s
expense (provided that Tenant shall be reimbursed for the Allowance as set
forth herein), in a good and workmanlike manner, and shall comply at the time
of completion with all Laws and Requirements. Tenant shall deliver to Landlord
copies of all certificates of occupancy, permits and licenses required to be
issued by any authority in connection with Tenant’s construction. Draws against
the Allowance shall be disbursed to Tenant by Landlord promptly (and in no
event later than thirty (30) calendar days) after submittal by Tenant to
Landlord of evidence of the costs and expenses of the leasehold improvements,
evidence of payment thereof by Tenant, and lien waivers from all persons supplying
labor or materials to the leasehold improvements.

The
Allowance may be disbursed in periodic draws, but no more frequently than
monthly. If the costs and expenses of the leasehold improvements in and to the
Premises exceed the Allowance, Tenant shall be solely responsible for payment
of any excess. In the event the budget for the leasehold improvements is
estimated by Landlord and Tenant to exceed 125% of the Allowance, Tenant will
either (i) directly pay (without recourse to the Allowance), and provide
Landlord lien waivers for, that portion of the construction costs sufficient to
bring the remainder of the budgeted costs within the Allowance, or (ii) deposit
the amount in excess of the Allowance with Landlord to be disbursed by Landlord
after the full disbursement of the Allowance, to insure that all construction
is completed lien free (any excess Tenant funds will be returned to Tenant upon
completion of the project and full payment of the project costs).

2.                                       Increase in Minimum Annual Rent. In consideration of the Allowance, the
Minimum Annual Rent for the Premises will be increased by $15,752.10 per month
(as set forth below), for the balance of the Term, commencing with the monthly
rent due October 1, 2005 and ending with (and including) the monthly rent due
October 1, 2009. The additional $15,752.10 per month amends Section 1(d) of the
Lease as follows going forward:

	
  PERIOD

  	
   

  	
  ANNUAL

  824,740.68

  	
   

  	
  $

  	
  68,728.39

  	
   

  

 

If
Landlord fails to fund the Allowance, or any portion thereof, the increase in
Minimum Annual Rent shall not be effective (or in the case of a partial funding
of the Allowance, the increase in Minimum Annual Rent shall be reduced
proportionately based on the unfunded portion of the Allowance); in such case,
Tenant shall be entitled to a refund from Landlord of any increase in Minimum
Annual Rent previously paid by Tenant under this Amendment in excess of the
reduced amount required to be paid by Tenant by virtue of a funding of less
than the entire Allowance.

3.                                       Letter of Credit.  In
consideration of this Amendment, the step-down (reduction) dates with regard to
the letter of credit issued to Landlord pursuant to Section 35 of the Lease
shall be postponed by one-year (however, the conditions to each reduction as
set forth in said Section 35 remain unaffected by this Amendment and continue
in full force), so that the minimum amount of the letter of credit shall be as
follows:

	
  DATE:

Landlord shall have no
obligation to disburse any portion of the Allowance until Tenant has delivered
to Landlord an original amended or replacement letter of credit conforming to
the requirements of the Lease and the revised reduction schedule. Nothing
contained herein shall be construed as a release by Tenant of its entitlement
to reduce the amount of the letter of credit and obtain a return by Landlord of
the letter of credit to the Tenant in accordance with Section 35 of the Rider
to the Lease.

4.                                       Waiver of Tenant’s Termination Right.
Provided that the Allowance is paid by Landlord, Section 34 of the Rider to
Lease [entitled, “Termination”] is hereby deleted and shall have no further
force or effect.

5.                                       Defined Terms. All capitalized
terms used in this Amendment not separately defined herein shall have the
meaning given them in the Lease.

6.                                       Full Force and Effect. All of the
terms and conditions of the Lease not inconsistent with this Amendment shall remain
unmodified and in full force and effect.

7.                                       Counterparts. This Amendment may be
executed in counterparts and may be delivered by facsimile transmittal of
