Vocus Promotes Current Vice President of Development Mark Heys to Chief Technology Officer

Co-Founder Robert Lentz Announces Retirement

LANHAM, MD., February 5, 2008 —Vocus, Inc., (NASDAQ: VOCS) a leading provider of on-demand software for public relations management, today announced the promotion of nine-year Vocus veteran and current Vice President of Development Mark Heys to the role of Chief Technology Officer. Heys will replace co-founder Robert Lentz who has announced plans to retire.

Heys has led software development at Vocus since joining the company as VP of Research and Development in 1998. Under his leadership, Vocus’ public relations software has won several awards and in 2007 was named “Best Business Productivity Software” by the Software and Information Industry Association. Heys will add the oversight of Information Technology to his current responsibilities and will officially take over as CTO on Friday, February 8, 2008.

Lentz co-founded Vocus along with Rick Rudman in 1992 and served as CTO during a period that saw Vocus grow from a garage-based start-up to a pioneer in software-as-a-service and whatForbes Magazinehas recently named one of the industry’s fastest growing technology companies. Lentz will continue to serve as a consultant to Vocus to aid in the transition and will also continue to serve as a Director of the company.

“Building Vocus into the market leader that it is today was something that was hard to imagine when Bob and I started the company 15 years ago,” said Rick Rudman, chief executive officer of Vocus, Inc. “Bob single-handedly wrote the early versions of Vocus software and had the foresight to build a great team anchored by Mark to oversee our migration to a SaaS model. We’ll continue to rely on his insight and counsel as an advisor and a member of the Board.”

“At the same time I’m excited to officially welcome Mark Heys to the management team,” continued Rudman. “Having him assume the CTO role ensures Vocus will continue to deliver innovative products without skipping a beat.”

“Collaborating with Rick and this outstanding management team over the last 15 years has been a fantastic experience and I look forward to continuing to work with them as a member of the Board of Directors,” said Lentz. “I’m thrilled to see Mark Heys step into the role that I’ve been grooming him for since I brought him to Vocus. He is one of the best architects of on-demand software in the industry and I know he’ll thrive in his new position.”
