     Trimble and McNeilus Form Alliance to Factory-Install Fleet Management
                     Solutions on Ready Mix Concrete Trucks


LAS VEGAS, March 19, 2002 - Trimble (NASDAQ:TRMB) and McNeilus Companies Inc., a
subsidiary of Oshkosh Truck Corporation  (NASDAQ:  OTRKB),  announced today they
have formed a strategic alliance to offer Trimble's fleet management solution as
a  factory-installed  and  aftermarket  option on  McNeilus'  ready mix concrete
mixers.  McNeilus,  the leading manufacturer of concrete mixers, will become the
industry's first to offer customers a complete  Internet-based  location service
to dramatically improve fleet utilization. Financial terms were not disclosed.

As part of the alliance, Trimble's recently introduced Telvisant Mobile Resource
Management System will be marketed, distributed and sold through McNeilus' sales
channel.   Customers   will  access   fleet   information   from  a   co-branded
McNeilus/Trimble Web site. In addition,  McNeilus and Trimble will work together
to develop future  technology that will continue to improve fleet management for
the concrete industry.

"McNeilus  has  always  focused  its  engineering  resources  on  improving  our
customers'  productivity,  because  we  know  that's  what  important  to  their
business," said Dan Lanzdorf,  president of McNeilus. "Working with Trimble puts
us at the  forefront of the industry by offering  our  customers  location-based
services.  The  technology is installed  right at the factory,  so our customers
have a single-source for the complete package. The new fleet management tool can
help  them  use  their  equipment  more  efficiently;  and that  means  improved
profitability."

"With more than 100,000 units in the field worldwide, Trimble has a long history
of providing  innovative fleet management  solutions to vertical  markets," said
Steven W.  Berglund,  Trimble's  president and CEO.  "The  combined  strength of
Trimble's  positioning  technologies  and McNeilus'  leadership in the ready mix
concrete  industry  puts the  alliance  on the  leading  edge of  location-based
services for the construction market."

McNeilus will offer Trimble's Telvisant Mobile Resource Management System on its
line  of  concrete  mixers.  Telvisant  is a  complete  solution  that  includes
hardware, wireless connectivity, software and service. The platform allows fleet
managers to use location-based  services to improve  productivity.  In addition,
the Telvisant platform is compatible with most dispatch and enterprise  software
products used by concrete producers.

To be efficient,  ready mix concrete  dispatchers must constantly check incoming
customer   orders  against   concrete   production   and  delivery   capacities.
Historically,  truck drivers have used radio,  cell phones, or text messaging to
send  information  to  dispatchers.  The problem:  drivers  must provide  status
updates  manually,  and  do  it  consistently.  Often  the  dispatcher  receives
incomplete or inaccurate information from the field.

Trimble's  Telvisant  Mobile Resource  Management  System solves this problem by
using Global  Positioning  System (GPS) technology and other sensors to automate
the delivery cycle.  Dispatcher's no longer need to depend on drivers for timely
status  information.  Instead,  they will receive automated  information via the
Internet  which  includes  truck status when  loading at the plant,  leaving the
plant,  arriving at the job,  starting  the concrete  pour,  ending the concrete
pour, washing the trucks, leaving the job, and arriving at the plant to complete
the delivery cycle. Trimble's Telvisant system automates the entire process.

McNeilus and Trimble are jointly exhibiting at ConExpo-ConAgg  2002, the largest
trade show in the Western Hemisphere for the construction,  aggregates and ready
mixed concrete industries,  in Las Vegas from March 19-23. The companies will be
showcasing the new fleet  management  solution at the McNeilus  booth.  For more

     Trimble and Systech to Integrate Fleet Management Solution and Dispatch
                     Software for Ready Mix Concrete Market


LAS VEGAS,  March 19, 2002 - Trimble  (NASDAQ:TRMB)  and Systech Inc., a leading
provider of enterprise software for the concrete and aggregate market, announced
today that they have signed an agreement to integrate  Trimble's  Internet-based
fleet  management  solution  with  Systech's  ready mix  dispatch  software.  By
seamlessly  integrating these products,  concrete  producers will have access to
the most advanced  automated truck tracking and dispatch solution offered in the
ready mix concrete industry for improved fleet operations.

The announcement was made at CONEXPO-CON/AGG 2002, the largest trade show in the
Western  Hemisphere  for the  construction,  aggregates and ready mixed concrete
industries.

As part of the  alliance,  Trimble  and  Systech  will  collaborate  to create a
two-way interface that seamlessly  connects Trimble's  Telvisant Mobile Resource
Management System with Systech's Advantage Dispatch 8.0 software.  The companies
will  also  jointly  market  and  distribute  the  integrated  solution  to  the
construction materials market.

"For the ready mix industry,  this is a `golden  spike'  event,"  explained John
Rabchuk,  president  and CEO of  Systech.  "With  GPS and  Internet-based  truck
tracking  technology  seamlessly  integrated  with  Windows-based  ticketing and
dispatch  software,  concrete producers now have a powerful new tool for driving
significant new productivity into their fleet operations."

"Trimble  provides  the  complete  value-chain  in  mobile  resource  management
including  in-vehicle  hardware,  applications,  services,  support and industry
standard  integration  interfaces,"  said Michael  Lesyna,  vice  president  and
general  manager of  Trimble's  Mobile  Solutions  Division.  By  aligning  with
Systech,  a leading supplier of dispatch software for the concrete and aggregate
market, we are providing  concrete producers with the most complete and advanced
fleet management solution to improve operations."

Telvisant Mobile Resource Management System is a complete solution that includes
hardware, wireless connectivity, software and service. The platform allows fleet
managers to use location-based  services to improve productivity.  The Telvisant
platform is compatible with many dispatch and enterprise software products.

Systech's  Advantage  Dispatch 8.0  streamlines  and accelerates the dispatching
process for ready mix and aggregate truck fleets. The fully Windows(R) compliant
software  application enables operators to enter comprehensive orders in four or
five clicks of the mouse. Screen,  window, toolbar and column layouts can all be
customized  to  fit  each  customer's   operation.   New   innovations   include
dual-monitor support,  pre-assignment of orders, and a dynamic time-of-day graph
that helps dispatchers manage peak demand periods more efficiently.

To be efficient,  ready mix concrete  dispatchers must constantly check incoming
customer   orders  against   concrete   production   and  delivery   capacities.
Historically,  truck drivers have used radio,  cell phones, or text messaging to
send  information  to  dispatchers.  The problem:  drivers  must provide  status
updates  manually,  and  do  it  consistently.  Often  the  dispatcher  receives
incomplete or inaccurate information from the field.

Trimble's  Telvisant  Mobile Resource  Management  System solves this problem by
using Global  Positioning  System (GPS) technology and other sensors to automate
the delivery cycle.  Dispatcher's no longer need to depend on drivers for timely
status  information.  Instead,  they will receive automated  information via the
Internet  which  includes  truck status when  loading at the plant,  leaving the
plant,  arriving at the job,  starting  the concrete  pour,  ending the concrete
pour, washing the trucks, leaving the job, and arriving at the plant to complete
the delivery cycle. Trimble's Telvisant system automates the entire process.

With the product  integration,  location  information  from Trimble's  Telvisant
system  automatically  drives  Systech's  software  status  information  for the
dispatchers,   without  driver  intervention.  To  streamline  the  dispatcher's
workflow,  a job ticket is created by Systech's  software and the information is
used to automatically define the job site. The ticket is then sent to the driver
on an in-vehicle  display to proceed to the job site.  As a result,  the Systech
dispatch  software becomes fully automated for  communicating  with and managing
the fleet.
