Steam Machines was invited to visit the N.E.D.U.(Navy Experimental Diving Unit) in November 1999 for a quick-look study. A quick look study does not include a full test and approval, only that the Navy has evaluated our unit.

Dear Mr. Readey:

SUBJECT: PRISM TOPAZ UNDERWATER BREATHING APPARATUS(UBA)

I would like to express my appreciation and thank you for providing us the opportunity to evaluate your
PRISM Topaz closed Underwater Breathing Apparatus(UBA.) Your time and effort has contributed to
our ongoing goal of providing Navy divers with the best available equipment on the market today.

Enclosed is a copy of our quick-look evaluation to the Naval Sea Systems Command in Washington,
D.C. This letter describes the form, fit, and function(FFF) evaluation of your PRISM Topaz UBA 
conducted at the NAVY Experimental Diving Unit(NEDU) in November, 1999.

We are continually monitoring advances in the commercial diving industry for potential Navy 
application. Until receipt of official tasking from the Naval Special Warfare Command, we are in the 
process of developing a UBA matrix reflecting current commercial technology as a decision of making 
tool for an Integrated Product Team. We believe the PRISM Topaz may be a potential candidate to 
replace the current MK 27 UBA. Again, I appreciate your time and effort to facilitate this testing and the
opportunity to dive your PRISM Topaz UBA.

Sincerely,
E.N. CHRISTENSEN
Commanding Officer
