Harris & Harris Group Notes Bridgelux and Toshiba Collaboration

NEW YORK, April 23, 2013 (GLOBE NEWSWIRE) -- Harris & Harris Group, Inc.
(Nasdaq:TINY), an early-stage, active investor in transformative companies,
notes today's announcement by Bridgelux, Inc., and Toshiba Corporation that
they have entered into an agreement under which Bridgelux will sell to Toshiba
its industry-leading GaN-on-Silicon technology and related assets, and the
companies will strengthen and extend their strategic technology collaboration
through an expanded licensing and manufacturing relationship.

In January 2012, Bridgelux and Toshiba entered into a Joint Development and
Collaboration Agreement for the development of GaN-on-Silicon LED
technologies. The success of that relationship was demonstrated by Toshiba's
announcements of the achievement of world class performance for 8"
GaN-on-Silicon LED wafers and mass production of white LEDs.Both of these
milestones were achieved using Bridgelux's crystal growth and LED device
technologies as well as Toshiba's advanced silicon processes and manufacturing
technologies. Bridgelux's press release may be viewed at

"When we made our initial investment in 2005, we knew that LEDs would become
an important growth market and that Bridgelux had novel and differentiated
technology. Today's announcement with Toshiba is another step towards
validating that decision almost eight years ago," said Douglas W. Jamison,
Chief Executive Officer of Harris & Harris Group. "Brad Bullington and the
Bridgelux management team should be commended for developing such a strong
relationship with Toshiba. This relationship is critical to maximizing the
substantial opportunity in the global LED market," added Dr. Alexei A.
Andreev, Managing Director at Harris & Harris Group and Bridgelux Board
Observer.
