FOR IMMEDIATE RELEASE
Aspen Technology Launches E-Business Initiative

AspenTech to offer process-centric manufacturers supply chain automation 
and
business-to-business e-commerce solutions via Extricity Software 
partnership

 CAMBRIDGE, Mass.--October 26, 1999--Aspen Technology, Inc. (NASDAQ: 
AZPN),
the leading supplier of manufacturing enterprise optimization solutions 
for
the process industries, today launched an e-business initiative and
announced Aspen e-Business, the first in a series of business-to-business
e-commerce applications.

As part of this initiative, AspenTech has partnered with
business-to-business application leader Extricity Software, Inc. to 
deliver
e-commerce solutions that will enhance integration and automate the flow 
of
information between disparate supply chain and enterprise resource 
planning
(ERP) systems and customers, suppliers and trading partners. Privately 
held
Extricity Software creates software that enables companies to aggressively
improve efficiencies, competitiveness and profitability by leveraging the
Internet to automate business interactions throughout entire value chains 
of
customers and partners.

AspenTech's e-commerce solutions will expand the company's existing
Internet-enabled capabilities into the business-to-business arena and 
create
new products based on Aspen MIMI and Aspen PIMS supply chain management
software. Through its partnership with Extricity, AspenTech will extend 
the
power of supply chain planning, scheduling and demand management beyond 
the
enterprise by integrating customers' business processes with those of its
trading partners. This extension expands AspenTech's industry-leading 
supply
chain capabilities beyond supply chain management and optimization to now
include the automation of all supply chain decisions. AspenTech currently
has more than 2,000 supply chain applications installed in the process
industries-more than any other supply chain vendor.

AspenTech will integrate Extricity's strong business processes modeling,
e-commerce and process execution technologies with its own process plant
modeling, automation and optimization systems. This integration will help
AspenTech's customers forge tighter relationships with partners by 
allowing
complex e-business transactions, regardless of the ERP, customer
relationship management, supply chain or other software in use at each 
node
in the trading network. AspenTech's unique solution is the only product 
that
permits integration among all of the ERP and supply chain applications
currently used in the manufacturing industries. This capability allows the
company to create integrated e-commerce solutions independent of any
previous application decisions made by the customer.

The AspenTech solution will not only support simple buy/sell transactions,
but will also help automate higher-level processes such as collaborative
forecasting, planning and replenishment, production scheduling and 
inventory
management.

"We selected Extricity to be part of our e-business initiative due to the
wide-spread recognition of its leadership in facilitating
business-to-business e-commerce among multiple trading partners," said 
Larry
Evans, Chairman and CEO of AspenTech. "We recognize the tremendous market
opportunity that exists for helping manufacturers to maximize their
efficiency, profitability and customer satisfaction through supply chain
automation and business process integration. These solutions will enable
manufacturers to be more responsive to customers and more rapidly identify
new areas of market demand."

"Extricity is pleased to have entered into a partnership with AspenTech to
provide the
business-to-business e-commerce capabilities behind its e-business
initiative in the process manufacturing industries, " said Ken Ross, CEO 
of
Extricity Software. "AspenTech's solution suite and detailed knowledge of
plant operations, combined with Extricity's business-to-business software,
will create powerful e-business and supply chain solutions that will help
AspenTech further build upon its leadership and success."
