Credit 8.1 delivers industry-leading functionality and performance as a fully integrated
component of Allegro 8

DALLAS, Texas, January 27, 2009 – Allegro, the leading provider of energy trading and risk
management (ETRM) solutions, has announced the release of Credit 8.1, a major upgrade to
that component of the Allegro 8 integrated ETRM solution suite.  Addressing the industry’s
urgent need for more robust measurement and monitoring of credit risk, Allegro has delivered
comprehensive capabilities with first-to-market functionality.

The Allegro 8 platform allows seamless integration of the company’s stand-alone business
solution components.  As a fully integrated component of Allegro 8, Credit 8.1 will provide
business managers with real-time all-the-time visibility into every facet of a company’s credit
position.  

Kevin Kohleriter, Allegro Director of Marketing, describes the company’s strategy:  “For an
industry keenly aware of the risks inherent to commodity trading, even well-managed energy
companies were caught flat-footed by the epic price fluctuations of 2008 and subsequent credit
market collapse.  Today, every energy-related transaction, from production to consumption,
faces increased credit and liquidity risks.  Credit 8.1 provides the tools and transparency to
meet the new challenge as no other solution can.”

Credit 8.1 is clearly a “next generation” ETRM solution and demonstrates, again, how Allegro
has stayed atop the industry for more than two decades:  by listening to customers.  The Credit
8.1 product development effort was collaboration with several of Allegro’s largest clients, each
representing different transaction models across the energy industry.  Their perspectives
influenced the product from its initial concept, and each company successfully tested the
solution in its real-world environment.

Most competitive solutions, when you look past the brands, are not fully integrated ETRM
components.  As a stand-alone credit risk management solution, Credit 8.1 still outperforms
those products with industry-leading functionality and connectivity.  For more information about
