                          PSDI ACQUIRES INTERMAT, INC.

  INTERMAT To Provide MRO.com's MROMarketplace and PSDI's MAXIMO Customer Base
             with Powerful Cataloging and Data Standardization Tools

BEDFORD, MASS., JANUARY 11, 2000 - PSDI (NASDAQ: PSDI), a leading provider of
enterprise asset maintenance (EAM) systems and MRO e-Commerce systems, today
announced it has signed a definitive agreement to purchase INTERMAT, Inc., a
leading provider of MRO content management tools and cataloging services. Under
terms of the agreement, PSDI will acquire the capital stock of INTERMAT from
Strategic Distribution, Inc. (NASDAQ: STRD) for approximately $55 million.
Closing of the transaction is subject to customary conditions, including
expiration of the waiting period under the Hart-Scott-Rodino Antitrust
Improvements Act of 1976. The closing is expected to be in the company's current
quarter and will be accounted for as a purchase.

While advances in technology have made it easier to access data critical for
indirect materials purchasing, the quality of the data and the "ease of use" to
access the data are still major factors that are far too inconsistent.
INTERMAT's expertise lies in its ability to standardize data by using its
Standard Modifier Dictionary(TM) (SMD) which features over 6,500 unique formats
for clear, concise, accurate descriptions of MRO parts and materials. The SMD is
the world's most widely implemented standard for the description of MRO and
general supply items. With the acquisition of INTERMAT, PSDI will add a robust
component to its existing technology for

MROMarketplace and for the company's MAXIMO installed base consisting of
thousands of end-users. MRO.com will be able to standardize descriptions for
industrial suppliers and buyers providing the ability to easily search for
supplies in the MROMarketplace catalogs.

Rich product content is mandatory and represents the most challenging component
of an MRO e-Commerce solution due to the volume and complexity of the data, and
the involvement of tens of thousands of distributors and manufacturers, each
with their own disparate sources of information. "A fundamental part of our
strategy is to offer content that is specific to the maintenance and repair
world," said Walt Vanderlaan, vice president, corporate development, MRO.com.
"Product classifications, item attributes, technical specifications, and digital
assets are crucial to the buying experience for the maintenance and purchasing
professional. Quality content is what drives the success of e-procurement
solutions. Without it, efforts to reduce costs for both the buyer and supplier
will not be fully realized."

"In the digital marketplace for MRO products, aggregated content is everything,"
said Chip Drapeau, president and CEO of PSDI. "The accessibility and quality of
the data is a fundamental piece of the Internet commerce puzzle. The company
that wins the content battle will win in the MRO e-procurement space. The
acquisition of INTERMAT is another critical step in our strategy to provide a
comprehensive solution for capital asset intensive industries to reduce costs
for buyers and sellers of MRO materials and supplies."

KEY COMPONENTS OF THE ACQUISITION INCLUDE:

INTERMAT'S STAFF OF MRO SUBJECT EXPERTS
Based out of INTERMAT's headquarters in Houston, Texas, the company's workforce
of 75 employees, including 56 MRO product experts, will serve as an important
component of MRO.com's content service offerings. These offerings will include;
MRO search capabilities, catalog creation, catalog analysis, data
standardization and enhancement, implementation, integration, and catalog
maintenance. INTERMAT president and CEO Gregg Enders will continue in his role
operating this business unit.

MRO.MASTER(TM)
MRO.Master is a database that contains comprehensive information on more than
two million of the most commonly used maintenance, repair, operations and
general supply items from major industries including process, manufacturing,
petrochemical, and utilities. Each item includes noun and modifier identifiers,
reference numbers, descriptive characteristics and values, synonyms, and
supplier name formatted to INTERMAT's SMD.

AUTOCON
The core of the content creation process is INTERMAT's proprietary AutoCon
system; a robust content processing engine and knowledge base with over 80,000
business rules specific to MRO material. AutoCon, coupled with INTERMAT's SMD of
over 6,500 MRO templates, will form the foundation of MRO.com's ability to
deliver industrial content rapidly to the MROMarketplace.

STRUXURE(R) AND CATALOGER'S ASSISTANT(TM)
Struxure and Cataloger's Assistant are the cornerstone of INTERMAT's Internet
catalog content management infrastructure. These software tools will allow
distributors and manufacturers to enrich and enhance their product data, and
through XML technology, allow them to maintain data in the MROMarketplace. This
centralized approach to remote catalog content management will allow
distributors and manufacturers to update and publish data once and immediately
make it accessible to all buyers.
