    NEW YORK--(BUSINESS WIRE)--July 26, 2000--

    Partnership Between Advanced Decision Support Engine and Premier Catalog Management
                       Technology Provider Fuels Transactions 

    ExpertCommerce, Inc. (www.expertcommerce.com), the sole provider of a proven online
business-to-business purchase-evaluation technology, today announced an agreement with Cardonet
Inc. (www.cardonet.com), a leading provider of catalog content enabling solutions for
business-to-business e-marketplaces, to jointly market ExpertCommerce's eValEngine(TM) and
Cardonet MarketStand(TM).
    ExpertCommerce's eValEngine provides an automated, powerful decision-making technology and
sophisticated analysis tools to drive purchase decisions. Cardonet's catalog content management
system, Cardonet MarketStand, provides the infrastructure necessary to effectively build and maintain
transactive catalogs. Under the terms of this agreement, the companies will work closely to pursue
joint sales opportunities that will significantly improve the quality of purchase decisions, drive customer
loyalty and lead to a larger number of consummated online transactions.
    "We are excited to be affiliated with ExpertCommerce and its very powerful decision support
technology," said Patrick O'Haren, Vice President of Marketing for Cardonet. "More complex
products and services are being sold online, driving a real need for a sophisticated decision solution
such as ExpertCommerce's eValEngine, which allows users to make `better' decisions and drive more
transactions."
    "Those businesses that utilize sophisticated catalog management systems like Cardonet's will lead
the pack," said Jon Fisse, President and COO of ExpertCommerce. "Solutions are only as good as
the data on which they are based and Cardonet MarketStand ensures quality data aggregation and
management. Combine that with ExpertCommerce's eValEngine technology which synthesizes and
evaluates large amounts of data based on user preferences, and you have a solution that is extremely
powerful."
    ExpertCommerce's eValEngine enables net market makers and suppliers to quickly establish
dynamic commerce, increase transaction volume and cement customer loyalty and enables buyers to
make more effective and efficient procurement decisions. By injecting marketplaces, supplier sites and
procurement platforms with powerful, intelligent decision support technology, ExpertCommerce
enables buyers to evaluate alternatives on multiple dimensions in real-time and enables suppliers to
gain unique insight into purchase behavior. The real-time evaluation technology drives more dynamic
and efficient exchange, auction, RFP/RFQ and catalog transactions. Results include more confident
customers who are better equipped with the knowledge resources to mitigate risk and increase ROI,
and thus customers who are more likely to complete transactions.
    As an automated content factory, Cardonet MarketStand helps companies build their infrastructure
for the efficient processing of supplier product information by creating transactive catalogs that make it
easier to find products quickly and more accurately. This enables e-marketplaces to automate the
entire publication, classification and aggregation process, resulting in lower implementation and
ongoing maintenance costs.
