       eINSTRUCTION FILES PATENT INFRINGEMENT SUIT AGAINST
            PROMETHEAN AS ITC INVESTIGATION CONTINUES

DENTON, TX (September 29, 2010) eInstruction Corporation, a premier global
provider of learning technology, announced today that it has filed a patent
infringement lawsuit in the U.S. District Court in the Eastern District of Texas
against Promethean, Ltd, a publicly held London-based company; and
Promethean, Inc., a Georgia based company, (collectively “Promethean”).

eInstruction alleges in its lawsuit that Promethean’s ActivSlate and ActivSlate 50
wireless tablets infringe upon certain aspects of a patent held for its Collaborative
Input System, (United States Patent Number U.S. Patent Number 6,930,673)
used in eInstruction’s Interwrite Mobi® and other products. Interwrite Mobi® is a
mobile interactive whiteboard system that enables multiple students and the
teacher to collaborate on lessons and activities run from a single computer.

On June 15, 2010, eInstruction filed a complaint with the International Trade
Commission (ITC) concerning Promethean’s alleged patent infringement, which
resulted in an ITC investigation into Promethean. Promethean then filed a
lawsuit in Texas on July 30 claiming false marking of the patent at issue in the
ITC case. The parties met in Washington, D.C. on Sept. 16 pursuant to the ITC’s
mandatory settlement conference requirements but did not reach an agreement.
Promethean filed another lawsuit on Sept.21 seeking invalidity of the patent in
the U.S. District Court for the District of Maryland.

 “Without a settlement of the ITC complaint and faced with Promethean’s
preemptive filings of the false marking and patent invalidity lawsuits recently, we
believe we had no choice but to file the U.S. District Court patent infringement
action against Promethean on Sept 28th in addition to continuing to pursue the
ITC Complaint,” said eInstruction’s Chief Executive Officer Steve Kaye.
“eInstruction will continue to vigorously defend itself from such unwarranted
patent infringement and unmerited legal attacks by Promethean or any other
company.”
