Selero & the Boston Equities Exchange in Production

DENVER, CO and BOSTON, MA - 2 April 2007

Selero, Inc. and the Boston Equities Exchange (BeX) announced today that Selero is in full production providing the end-to-end STP backbone at BeX. That includes internal integration, external gateways, and administrative interfaces used for listed and OTC order routing, order handling and back office processing.

“Selero connects systems regardless of message protocol, provides flexibility in a highly dynamic environment, extends application processing capabilities and makes operational efficiencies possible with its administrative interfaces,” said Yann L’Huillier, Chief Information Officer at BeX

BeX was launched in late 2006 to provide next generation trading tools within the National Market System, offering retail and institutional investors the automated tools, quality executions and cost structure needed, while helping to manage financial and regulatory risk.

“The BeX team worked closely with Selero to implement a highly complex, multi-dimensional technology platform,” said Fred Horn, Chief Executive Officer of Selero.

Selero provides BeX with access to outside entities through order-entry customer gateways that support the FIX, MMTP©, and CMS protocols; a ticker plant gateway; and the SIAC and SIP reporting gateway.

Inside the Exchange, Selero provides back office connectivity for applications. It performs real-time monitoring and management of trade status and system monitoring.

Currently, Selero is running the BeX program for certifying new customer connections and participating in ongoing enhancements.
