FAIRFAX, VIRGINIA -- February 12, 1997 -- AAROFLEX, Inc., its parent company
AAROTECH Laboratories and its founder Albert C. Young, Jr., have each
announced receipt of the complaint filed by 3D Systems, Inc. in the United
States District Court - Central District of California alleging patent
infringement, trade libel and federal and state unfair competition.

The suit alleges infringement of six (6) United States Patents assigned to
3D Systems. These are U.S. Patent Numbers 4,929,402; 5,059,359; 5,137,662;
5,174,931; 5,184,307 and 5,571,471. The suit further alleges AAROFLEX has
misrepresented 3D equipment specifications and quality, and falsely
represented its patent protection. AAROFLEX's Kaisha Halcli states that the
companies and Young each deny the allegations and intend to aggressively
defend their technology, business practices and customers. According to
Young, "AAROFLEX is anxious to bring this issue to a speedy conclusion so
that both companies may return the focus of their energies and resources to
technical enchancement and service to best serve the needs and growth of the
rapid prototyping industry."
