MatrixOne and IntegWare Enter into Business Alliance to Deliver Product Compliance Solutions to the Medical Device Industry

   Business Alliance will Enable Small to Medium-Sized Businesses to
Take Advantage of PLM to Significantly Ease FDA Regulation Compliance
Efforts

   MatrixOne, Inc. (NASDAQ: MONE), a leading provider of
collaborative product lifecycle management (PLM) solutions for the
value chain(TM), today announced that it has entered into a reseller
agreement with IntegWare, Inc., a company that designs, develops,
deploys and sustains enterprise PLM solutions to help customers build
their products better, faster and more profitably. Under the
agreement, IntegWare will strive to deliver rapidly implementable FDA
compliance and process automation solutions to the medical device
industry.
   Companies currently using paper-based systems to meet FDA
requirements are putting themselves at risk and are operating at a
competitive disadvantage due to the extra time and effort needed to
secure compliance. The electronic workflow provided by PLM solutions
can streamline quality assurance and compliance, while helping to
improve profitability through improved business process and faster
time-to-market.
   "This alliance will enable our clients to draw upon the strengths
of both companies," said Chris Kay, CEO of IntegWare. "Our medical
device domain expertise and MatrixOne's FDA compliance solution will
create a powerful tool for medical device businesses that have not yet
been taking advantage of the streamlined regulation compliance and
approval processes that PLM solutions enable."
   As a part of the reseller agreement, the two companies will focus
on providing FDA compliance and process automation solutions using the
MatrixOne Accelerator for FDA Compliance(TM). The Accelerator for FDA
Compliance is a single comprehensive solution designed to enable
medical device manufacturers achieve compliance throughout their
product lifecycle processes, drastically reducing product development
costs and delivering products to market quicker than the competition.
   "IntegWare's expertise in the product development market paired
with our industry-leading PLM platform will give small-to-medium sized
businesses an "out-of-the-box" solution that can be rapidly
implemented and quickly transform the way they secure FDA compliance,"
said Mayur Shah, vice president of business development, alliances &
industries for MatrixOne. "This alliance will enable a wider-range of
companies to take advantage of improved product development and
compliance process efficiencies. We're happy to be furthering our
partnership with IntegWare."
   IntegWare's domain expertise in product development and
manufacturing and extensive experience with assessing and optimizing
the product development process (PDP) allows the company to bring
unique value to clients across all phases of a PDP improvement
project. From initial needs assessment and PLM strategy definition
through solution development, validation, deployment and support,
IntegWare's holistic approach and focus on each client's key business
drivers ensures a direct and positive impact to the bottom line,
especially for those clients in global or highly regulated markets.
   MatrixOne's Accelerators program packages specific vertical market
expertise with MatrixOne technology to deliver industry-specific,
rapidly implemented PLM offerings that can solve focused product
lifecycle management challenges inherent to specific industries. The
Accelerators enable companies to meet their unique product development
challenges by providing users with industry-specific terminology, data
models, work processes, reports, role-based user interfaces and
document management capabilities. In addition to the medical device
industry, MatrixOne offers Accelerators aimed at the electronics
industry (MatrixOne Semiconductor Accelerator for Enterprise Project
Management(TM) and the MatrixOne Semiconductor Accelerator for
Design-to-Manufacturing(TM)) and the apparel industry (MatrixOne
Accelerator for Apparel Design & Development(TM)).
