The Initial Lease and Amendments Nos. 1 through 10 are sometimes collectively referred to herein as the “Current Lease.”

     B. The Current Lease relates to the Leased Premises consisting of approximately 26,301 rentable square feet on the fourteenth and fifteenth floors of the building commonly known as 8500 Normandale Lake Boulevard, Bloomington, Minnesota (the “Building”), and comprised of the following parcels:

     Approximately 5,556 rentable square feet on the fifteenth floor (“Suite 1550”).

     FOR VALUABLE CONSIDERATION, the receipt and sufficiency of which are expressly acknowledged, the parties agree as follows:

     1. Effect. The Current Lease is hereby amended to the extent necessary to give effect to this Amendment, and the terms of this Amendment shall supersede any contrary terms in the Current Lease. All references in the Current Lease to “this Lease,” and all references in this Amendment to “the Lease,” shall be deemed to refer to the Current Lease as amended by this Amendment. In all other respects, the terms and conditions of the Current Lease shall remain unmodified and in effect. Unless otherwise defined herein, capitalized terms used in this Amendment shall have the same meanings as provided in the Current Lease.

     2. Term. The term of the Lease is hereby extended for one (1) period of sixty (60) months commencing on October 1, 2007, and ending on September 30, 2012 (“Third Extension Term”). Except

as expressly provided otherwise in the Lease or this Amendment, the Lease shall continue during the Third Extension Term on all of the same terms and conditions, and any reference in the Lease to the term of the Lease shall be deemed to include and refer to the Third Extension Term. This Amendment shall not be deemed to grant to Tenant any right or option to further extend or renew the Lease, and any options to extend or renew contained in the Lease are hereby deleted.

     3. Leased Premises.

     A. For purposes of this Amendment, the “Relocation Date” shall mean the earlier of: (1) the date of substantial completion of the Tenant Finish Work in Suite 1130 pursuant to the attached Exhibit 2, or (2) the date Tenant occupies all or any part of Suite 1130 for the conduct of business. The Relocation Date is currently estimated to occur on approximately March 1, 2007. If the Relocation Date is delayed, Tenant’s obligation to pay rent for Suite 1130 shall be postponed until the Relocation Date occurs (except in the case of Tenant Delay as provided in the attached Exhibit 2), Landlord shall not be liable for such delay, and the term shall not be extended or affected thereby.

      B. As of the Relocation Date, Suite 1550 shall be entirely deleted and released from the Lease, and Tenant shall completely vacate Suite 1550 and surrender possession thereof to Landlord in the condition required under the Lease, reasonable wear and tear excepted. Tenant shall at its expense remove all of Tenant’s trade fixtures, personal property, equipment, and telecommunications and computer wiring from Suite 1550, and repair any damage caused by such removal, moving, or installation.

     C. As of the Relocation Date, the Leased Premises shall be amended and expanded so that the Leased Premises thereafter shall consist of a total of approximately 31,930 rentable square feet, and shall be comprised of Suite 1400 and Suite 1130. Except as expressly provided otherwise in this Amendment or in the Lease, Suite 1130 shall be added to and become part of the Leased Premises for the remaining term of the Lease (including the Third Extension Term and any extension thereof) on all of the terms and conditions of the Lease, and any reference in the Lease to the Leased Premises shall thereafter be deemed to refer to Suite 1400 and Suite 1130.

     D. If Tenant holds over in Suite 1550 after the Relocation Date, in addition to Landlord’s other rights and remedies under the law and the Lease: (1) Tenant shall pay holdover rent for Suite 1550 at one hundred fifty percent (150%) of the rate for Base Net Rent and Operating Costs payable by Tenant for such space during the month preceding the Relocation Date, computed on a daily basis for each day Tenant remains in possession of Suite 1550; and (2) Landlord shall be entitled to lawfully retake possession of Suite 1550 and to recover from Tenant all costs, reasonable attorneys’ fees and consequential damages sustained by Landlord as a result of such holding over by Tenant.

     9- Brokers.
