SANTA MONICA, CA – January 11, 2012 – Clearlake Capital Group, L.P. (“Clearlake”) today announced that it has sponsored the recapitalization of Entelos Holding Corporation (“Entelos” or the “Company”), provided a significant capital infusion and has taken a majority stake in the Company.

Steve Chang, Clearlake Founding Partner, said, “We are excited about our new partnership with Entelos, which offers the best-in-class technology and scientific talent. With a strong management team, a clear market vision in a new healthcare environment and improved financial resources, we believe the Company is poised to take advantage of growth opportunities as pharmaceutical and consumer product companies look to improve their product development capabilities.”

“This completes a transformation undertaken over the past six months to restructure Entelos and position the Company for future growth,” said Shawn O’Connor, CEO of Entelos. “This funding provides the Company with a strong financial foundation to support the continued delivery of our unique in silico modeling and simulation products and consulting services, invest in and continue developing our products and services, and extend the reach of our sales and marketing. Importantly, it brings to Entelos a strong and experienced investment partner to support our future success. I am very pleased with our progress and look forward to many years of continued success.”
