AMENDMENT TO COMMERCIAL LEASE NO. 2

BETWEEN THE UNDERSIGNED:

ANIMUS, a French limited liability company with capital stock of 8,000 € having its registered office at Chemin Doyen Gosse, 38330 Saint Ismier, France, recorded in the Commercial Register of Grenoble under No. 403 348 501, represented for purposes of this agreement by Alain Tornier in his capacity as manager,

Represented by Mr. Alain Tornier in his capacity as manager,

Hereinafter “THE LESSOR”,

THE PARTY OF THE FIRST PART

and “TORNIER”, a société par actions simplifiée with capital stock of 311,024 €, having its registered office at Rue Doyen Gosse - 38330 Saint Ismier, recorded in the Commercial Register of Grenoble under No. 070.501.275, represented by Douglas Kohrs, Chairman and CEO,

Hereinafter “THE LESSEE”,

THE PARTY OF THE SECOND PART

The parties agree as follows:

RECITALS

The Lessee hereby gives the Lessor notification of the following changes in the legal organization of the TORNIER Group during the 2007 fiscal year:

Under the terms of a decision by the single shareholder dated July 31, 2007, TORNIER HOLDING SAS was absorbed in the form of a merger by TORNIER SAS, a transaction that included the transfer of all of its assets, rights and obligations. TORNIER SAS is therefore subrogated for TORNIER HOLDING in the lease between the latter company and ANIMUS Sarl, whereby the change of party was recorded in a supplemental agreement duly signed on July 31, 2007.

Under the terms of a decision by the single shareholder dated December 29, 2007, TORNIER MEDI-QUAL Sarl was dissolved with a transfer of all of its assets and liabilities to TORNIER SAS, which has its registered office in Saint Ismier (38330), Rue Doyen Gosse, and is a société par actions simplifiée recorded in the Commercial Register maintained by the Tribunal of Commerce of Grenoble under No. 070 501 275. TORNIER SAS therefore assumes responsibility for the lease of the above-mentioned company covering the premises located in Montbonnot (38330), 161 rue Lavoisier, for use as follows:

· offices 140 m2

· storage 1553 m2

· lunchroom 10 m2

plus a parking area of 461 m2, in exchange for an annual rent, net of taxes, of 92,426 € with a security deposit of 46,213 €, corresponding to 6 months rent, as a guarantee of payment of the rent.

1

Consequently, for reasons of administrative simplification, the lessee would like to transfer from TORNER COMMERCIAL to TORNIER SAS the commercial lease executed on May 30, 2006, covering the premises located in Montbonnot (38330), 161 rue Lavoisier, for the uses listed below:

· offices 101 m3

· storage 111 m2

· lunchroom 10 m2

plus a parking area of 57 m2 in exchange for an annual rent, net of taxes, of 17,767 €, with a security deposit of 8,883 €, corresponding to 6 months of rent, to guarantee payment of the rent.

The purpose of this supplemental agreement is to modify the description of the leased areas, which have been increased from the areas indicated in the commercial leases signed on May 30 and 31, 2006, by the Lessor with, respectively, TORNIER COMMERCIAL Sarl and TORNIER MEDI-QUAL Sarl.

AGREEMENT

The “Lessor” having agreed to the subrogation of TORNIER SAS in the rights and obligations of the leases described in the “Recitals” section of this Agreement, the parties have agreed that their new relationship shall be governed by this Supplemental Agreement.

Consequently, the “lessor” leases, subject to the terms and conditions set forth below, to the “Lessee”, which accepts, the property described below:

·              storage / equipment 1739 m2

·              lunchroom 72 m2

The rent shall be adjusted on the basis of this clause every 3 years counting from the date of entry into force of the lease. The rent shall vary by the same percentage as the selected index. The indexing shall enter into force automatically without the requirement for prior notification.

If the selected index is no longer published or can no longer be applied for any reason whatever, it shall be replaced by the closest index, which shall be identified, in case of doubt, by an expert acting for both parties, appointed by agreement between them or, if no agreement can be reached, by an order of the President of the court in response to a petition from the more diligent party. If the expert declines to accept the assignment, resigns or is unable to perform the task for any reason whatever, a replacement shall be appointed in the same manner.

The reimbursement to the lessor of all these charges or expenses shall be made at the same time as the payment of each installment of the rent in the form of provisional installment payments, with a final settlement once a year.

22/          CANCELLATION

If the lessee refuses to vacate the premises, it may be evicted without delay by a simple interim order issued by the President of the Regional Court of Grenoble and immediately enforceable, notwithstanding any appeal.
