                       DEREGISTRATION OF UNSOLD SECURITIES

         This Post-Effective Amendment No. 1 to Form S-8 Registration Statement
relates to the Registration Statement on Form S-8 (File No. 333-92176) (the
"Registration Statement") of MedSource Technologies, Inc. (the "Company")
pertaining to 5,119,961 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 July 10, 2002. The Registration Statement
registered 4,409,292 shares of Common Stock for sale pursuant to the Company's
1999 Stock Plan (the "1999 Plan"), 210,669 shares of Common Stock for sale
pursuant to the Company's 1998 ACT Medical Stock Plan (the "Act Plan") and
500,000 shares of Common Stock for sale pursuant to the Company's 2001 Employee
Stock Purchase Plan (the "ESPP" and, collectively with the 1999 Plan and the Act
Plan, the "Plans").

         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 Plans and all outstanding options under Plans were
terminated at the Effective Time.

         As a result of the Merger and the termination of the Plans, 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.
