II-VI Incorporated Announces Acquisition of Max Levy Autograph, Inc.

PITTSBURGH, Dec. 7, 2010 (GLOBE NEWSWIRE) -- II-VI Incorporated (Nasdaq:IIVI)
today announced the acquisition of Max Levy Autograph, Inc. (MLA). MLA
manufactures micro-fine conductive mesh patterns for optical, mechanical and
ceramic components for applications such as circuitry, metrology standards,
target calibration and suppression of Electro-Magnetic Interference (EMI) from
its 30,000 square foot manufacturing location in Philadelphia, Pennsylvania. The
MLA team of research and manufacturing engineers has also developed technologies
utilizing electro-forming and plating and micro-fine diamond contouring for
precision patterns on various substrates to service the medical and commercial
markets. MLA's technology is key to the military market as it provides
protection for intelligence, surveillance and reconnaissance systems for various
aircraft and land vehicles. During this past year, MLA has also become a
qualified supplier to II-VI's Exotic Electro-Optics, Inc. (EEO) subsidiary for
various products which require EMI gridding. MLA's 30 person workforce generated
revenues of approximately $5 million for the 12 months ended September 30, 2010.
Financial terms of the transaction were not disclosed.

Francis J. Kramer, president and chief executive officer of II-VI Incorporated
stated, "MLA adds products and technology well matched with the products and
markets served by our EEO subsidiary. During the qualification of MLA as a
supplier of EMI grids it became clear the combination of these groups would
provide a stronger platform for continued growth in the defense industry and
potentially enable market diversification over the longer term. As such, MLA
will operate as part of our EEO subsidiary which is consolidated into our
Military & Materials business segment. We are delighted to welcome the MLA
employees to our company."

Donald Sedberry, president and major shareholder of MLA commented, "This
acquisition provides an excellent opportunity to continue MLA's long history of
supporting our customers with advanced technology development, plus it sets in
place a solid foundation for growth. The management, technical and manufacturing
personnel of MLA, EEO and II-VI Infrared Optics have worked effectively together
and developed a high level of respect for one another. This merger is expected
to improve our capabilities to serve our current customers and uncover
opportunities to expand our business. We believe the innovative and energetic
MLA team is a great fit with the culture and technology of EEO."
