Exhibit 10.8.3
AMENDMENT TO NON-COMPETITION AGREEMENT
This AMENDMENT (this "Amendment") to that certain Non-Competition Agreement (the "Non-Competition Agreement"), dated May 31, 2000, among Medical Device Manufacturing, Inc., a Colorado corporation ("MDMI"), UTI Corporation, a Pennsylvania corporation ("UTI-PA") and Jeffrey M. Farina ("Farina") is dated as of December 1, 2003.
RECITALS
Whereas, in connection with his employment by MDMI and UTI-PA, Farina entered into the Non-Competition Agreement which incorporated certain exceptions to his agreement not to compete with MDMI and UTI-PA permitting him to perform certain services for eVasc, L.P., which exceptions the parties, by course of business, have extended to include the performance of certain services (the "Permitted Services") for Medical Device Investment Holdings Corporation, a Delaware corporation ("MDIH");
Whereas, MDIH and UTI-PA have entered into that certain Consent and Release Agreement (the "Consent Agreement"), dated of even date herewith, whereby UTI-PA has consented to the assignment of certain intellectual property rights licensed by UTI-PA to MDIH from MDIH to Abbott Vascular Devices Ireland Limited ("Abbott") and has agreed to a release of certain rights of UTI-PA against Farina;
Whereas, a material inducement and a condition precedent to UTI-PA's willingness to enter into the Consent Agreement was Farina's agreement to terminate his right to perform the Permitted Services for so long as the restrictions of the Non-Competition Agreement continue to apply; and
Whereas, Farina will personally benefit in a material way from UTI-PA's execution and delivery of the Consent Agreement and UTI-PA's consent to the assignment of the aforementioned intellectual property rights from MDIH to Abbot, which consent UTI-PA had the right to withhold and constitutes material consideration to Farina.

2. The Non-Competition Agreement is amended by inserting the following at the end of Section 1(d):
"Ownership by Farina, solely as a passive investment, of any equity interest in MDIH shall not constitute a breach of thisSection 1.

3. Issues and questions concerning the construction, validity, enforcement and interpretation of this Amendment shall be governed by, and construed in accordance with, the laws of the State of Pennsylvania, without giving effect to any choice of law or conflict of law rules thereof.
