                       DEREGISTRATION OF UNSOLD SECURITIES

         This Post-Effective Amendment No. 2 to Form S-8 Registration Statement
relates to the Registration Statement on Form S-8 (File No. 333-112422), as
amended (the "Registration Statement"), of MedSource Technologies, Inc. (the
"Company") pertaining to 500,000 shares of the Company's common stock, par value
$0.01 per share ("Common Stock"), which was filed with the Securities and
Exchange Commission and became effective on February 2, 2004. The Registration
Statement registered 500,000 shares of Common Stock for sale pursuant to the
Company's 2001 Employee Stock Purchase Plan (the "ESPP").

         On June 28, 2004, the stockholders of the Company approved and adopted
an Agreement and Plan of Merger, dated as of April 27, 2004 (the "Merger
Agreement"), by and among the Company, Medical Device Manufacturing, Inc.
("MDMI") and Pine Merger Corporation ("Pine"), pursuant to which Pine would be
merged with and into the Company (the "Merger") with the Company surviving the
Merger as a wholly owned subsidiary of MDMI upon the filing of a Certificate of
Merger with the Secretary of State of the State of Delaware. The Certificate of
Merger was filed with the Secretary of State of the State of Delaware, and the
Merger became effective on June 30, 2004 (the "Effective Time"). Pursuant to
the Merger Agreement, the ESPP was terminated at the Effective Time.

         As a result of the Merger and the termination of the ESPP, the offering
pursuant to the Registration Statement has been terminated. In accordance with
an undertaking made by the Company in the Registration Statement to remove from
registration, by means of a post-effective amendment, any of the securities
registered under the Registration Statement that remain unsold at the
termination of the offering, the Company hereby removes from registration the
securities of the Company registered but unsold under the Registration
Statement.
