When will the BAT RF products be available?

Are your sensors compatible with other RFID systems or Readers?

therefore can not be read by other systems. Sensor data can, however be
integrated with many popular tracking systems via our mobile onboard reader.

Are sensor batteries replaceable?

the environment. Battery life is sufficiently designed for a long, maintenance
free life.

What is the battery life of the sensors?

TracBAT).

What is the operational temperature range of the sensors?

What frequencies do BAT RF sensors use?

medical(ISM) band. They use a spread spectrum protocol which enhances their
immunity from interference.

Are your sensors approved for use in any other countries?

Are there other sensors in your plan?

architecture.

How may miles of testing have been done?

What is the price of the AirBAT sensor?

The purchase price is $129.95 for a dual tire sensor or $64.95 per tire. On a
per tire basis the sensor will monitor 3 - 4 tires during its service life. That
brings the cost per tire to $21.65 and $16.45 respectively per tire. One sensor
unit monitors two tires – with a 7 year battery life we anticipate a fleet using
the sensor on 3 or 4 sets of tires.

What is the warranty on the AirBAT sensor?

AirBAT has a 1 year warranty.

Does the AirBAT cold compensate?

No, we provide an accurate measurement of the actual tire pressure. Cold
compensation causes confusion for maintenance personnel. When adjusting cold
tires pressure readings should be actual. Industry mechanics are already
accustomed to checking tires cold rather than hot to prevent under inflation.

What is the operating pressure range of AirBAT?

20psi to 150psi.

Are there any temperature range issues with the AirBAT?

No, AirBAT maintains a +/- 3 PSI accuracy across the full operating pressure
range.

How long does it take to install AirBAT?

About 5 minutes per wheel end.

Does AirBAT require the tire to be dismounted or removed?

No... AirBAT is externally mounted to the wheel hub cap or lug nuts with a
simple bracket. Installation is quick and easy.

Are the hoses on AirBAT serviceable in the field?

No. Our strategy is to provide a long-life, maintenance-free sensor.
Customers do not want to trade tire maintenance headaches for hose replacement.

Does the AirBAT affect tire balance?

The AirBAT mass is sufficiently low as to not affect balance when mounted
near the center of rotation with the recommended bracket.

Do you offer AirBAT for steer tires or wide-based singles?

Our initial offering is a dual tire sensor. However, we plan to introduce a
single wide application mid to late next year. Steer tire applications present a
much more challenging application. However, we expect this solution to be
available in 2009.

Can AirBAT alert me of a tire problem while on the road?

We are currently developing a solution for this through our partnership with
SkyBitz

Can AirBAT equalize duals or inflate tires?

No. Although products like these can offer benefits, we believe the simplest
solution is the best.

Will AirBAT comply with any future regulations for in-cab warning of low
tire pressures?

Although no specific legislation has been handed down, we are closely
monitoring government activity in this area. It is our intention that AirBAT
will enable fleets and OEM’s to quickly comply with any rulings passed by
government.

What is the price of the TracBAT sensor?

TracBAT is $125 with a 7 year expected service life.

What is the warranty on the TracBAT sensor?

TracBAT has a 1 year warranty.

What is the accuracy of TracBAT?

+/- 2% over the life of the unit.

What are the limitations of TracBAT?

Excessive speeds (above 95mph for typical 22.5” rims) are not accurately
supported. The LCD can cease to display in extreme cold (less than -20F).
However, the unit can still be read by all BAT RF Readers in these conditions.

How much does a gate reader cost?

Gate reader costs average $10k - $15k depending on the site.

How long does it take to install a gate reader?

A gate reader can typically be installed in 2 to 3 days with minimal
disruption to traffic flow through the gate.

Can I install the gate reader myself?

No... Each installation is custom configured to your needs and requires the
skills of a specialized team.

Does STEMCO offer a turnkey installation option for fleets wishing to
rapidly deploy the system?

Yes... STEMCO can coordinate an installation plan tailored for your fleet
locations and needs to quickly and efficiently complete the deployment for rapid
realization of the value equation.

What are the fees for the WebBAT?

Contact a representative for the current pricing model.

How often will WebBAT require upgrading?

Because WebBAT is an internet application, any and all upgrades will be made
available to all customers as they are released without need for local upgrades
or installation. New features will be added to WebBAT as the system is expanded.
We expect there to be two primary releases per year.

Who is currently deploying the system?

We have 80 fleets using the passive system currently. A number of them are
migrating to the active solution. However, we do not have permission to use
their names at this time. We are working with an industry leader in the lease
rental segment to deploy the solution for evaluation at 3 locations. We have a
PO in hand to deploy AirBAT for a 3,000 trailer fleet. We are in the final
evaluation stage with 4 fleets including an 18,000 vehicle deployment of our
automated mileage collection system.

Have you validated the fuel savings in your ROI model?

The savings are real. Both the government and TMC have reported that inflated
tires save fuel. The amount of savings depends on how far off the set point your
tire pressures average and the effectiveness of your current tire program.

Have you validated the tire savings in your ROI model?

As with fuel, the industry has a number of studies on the savings related to
proper inflation.
