Exhibit A:

Heritage Design Modification Review

A 20 year old missile design needed a component part modification due to obsolescence. The original design specification required Electro-Magnetic Pulse (EMP) resistance.

TCA, Inc. was contacted to procure the services of a Ph.D. with expertise in Electro Compatibility and EMP design. TCA was able to contact the expert and, within 24 hours, this individual was signed on and working the problem. The expert reviewed the original EMP requirements versus the application of the new component.

A report was generated and provided to the contracting agency, Ballistic Missile Defense Organization (BMDO) within two weeks allowing them to approve the proposed change.
