L-3 Donates Aircraft and Pilot Time to Deliver Medical Supplies for Haiti Relief Effort

GRAND RAPIDS, Mich., January 27, 2010 – L-3 Avionics Systems’ chief pilot, Todd Scholten, and Mark
Linsley, aftermarket business development representative and pilot, left Tuesday afternoon to deliver
desperately needed medical supplies for the Haiti earthquake relief effort. They will fly L-3 Avionics’
company King Air C90 aircraft. L-3 Avionics and sister division ACSS, have donated a total of $25,000 for
fuel and aircraft expenses to conduct six to eight relief flights. The aircraft can hold approximately 1,300
pounds of medical supplies per trip.

“The employees of L-3 Avionics Systems are a very caring and generous group, and these flights
represent their commitment to help others in need,” said Jay LaFoy, president of L-3 Avionics. “L-3
Avionics and ACSS are donating the funds for this effort on behalf of our employees.”

The International Association of Missionary Aviation (IAMA) notified Mr. Linsley that pilots and aircraft
were urgently needed to transport medical supplies to Haiti. IAMA connected the L-3 Avionics’ pilots with
G.O. Ministries, a 501c3 organization headquartered in Louisville, Ky., which has aid bases in the
Dominican Republic and Haiti. This organization is dispersing medical supplies to Haiti through Santiago,
Dominican Republic, with a team of pilots flying shifts 24 hours a day. The L-3 Avionics’ pilots will fly
supplies to a G.O. Ministries base in Santiago where G.O. Ministries volunteer pilots will fly the remaining
leg into Haiti.

L-3 Avionics’ Roger Powers, principal engineer and test pilot, and James Powers, aircraft maintenance
technician (A.M.T.) will be assisting the effort by driving supplies from G.O. Ministries in Louisville to
Florida, where the King Air can quickly reload and make multiple flights between Florida and the
Dominican Republic.

L-3 Avionics Systems has been helping pilots fly for more than 45 years. The company provides a wide
array of avionics technologies designed to improve situational awareness and enhance safety, such as
the GH-3000 electronic and J.E.T.® standby instruments, the SkyWatch® Collision Avoidance System,
