Denver, CO – June 18, 2007 – Selero, Inc. announced today that it has expanded its processing and product footprint in the Sector Data Center in New York to accommodate its growing business.

Now, Selero supports all of its product and service offerings in the Sector data center in order to provide minimum latency and maximum throughput to its customers. For example, the Company runs its Reg NMS Smart Order Routing, its Trade Execution System, and its end-to-end order routing network there. Sector’s close proximity to the heart of Wall Street puts it close to the two largest U.S. stock exchanges, NYSE and NASDAQ, and close to a high concentration of current and prospective Selero customers. In addition, Sector’s SFTI network delivers the high throughput Selero’s customers and partners require. In fact, the NYSE and many Selero customers and partners currently run their servers out of the same Sector location and/or have direct connections into the SFTI network.

In addition to its New York data center, Selero has data centers in Chicago and Washington, DC.
