PRESS RELEASE
DATE: April 2, 2010
To Whom it May Concern:

Effective April 2nd, 2010, Teledyne Analytical Instruments (TAI) shall no longer accept orders for oxygen sensors intended for use in the commercial, underwater closed circuit rebreather (CCR) and semi-closed rebreather (SCR) markets.

TAI shall continue to focus on the oxygen sensing opportunities within its core
industrial, medical, automotive and above-water, diving-cylinder verification markets.

Any questions or concerns with regard to this decision should be sent to
ask_tai@teledyne.com.

Ambient Pressure already has a replacement source they will be using when the existing TAI stock is depleted.

They will continue to warranty all TIA cells.
