Purchase by Parthenon Capital Marks End of Successful Three-Year Investment

(Chicago, IL – August 31, 2006) – Chicago Growth Partners LLC (“CGP”), a Chicago-based private equity firm that focuses on lower middle market growth companies, today announced it has sold 100% of its interest in PRIMIS Marketing Group to Parthenon Capital. The sale marks the end of a successful three-year investment in the company.  Founded in June 2003 behind a core growth strategy to “buy and build” in the fragmented marketing information services industry, PRIMIS has grown to become the premier provider of comprehensive marketing data and analytics to the middle market. PRIMIS’ initial platform, AccuData America, Inc., is the largest independent provider of compiled marketing data and database analysis services in the United States. Over the past three years, through the continued support of Chicago Growth Partners, PRIMIS completed three additional acquisitions: Hyphos360, a provider of marketing database management solutions; MarketModels, a provider of high-speed marketing automation technology; and CoReg360, a provider of online co-registration marketing solutions. In combination, these four businesses offer an attractive, complementary set of data, database management, and analytical services and technologies that can be naturally extended and cross-sold to their respective customer bases.

“We have thoroughly enjoyed working with the terrific group of folks at PRIMIS,” stated CGP Partner Bob Blank. “The company’s success serves as an excellent example of the superior investment results that can be achieved through the partnering of a committed equity sponsor with the vision of an exceptionally talented and dedicated management team.”

In addition to CGP’s capital commitment, PRIMIS benefited from CGP’s value-add capabilities in the IT arena.

“PRIMIS management fully utilized CGP’s technology capabilities to both solve and implement solutions to the strategic and tactical issues so critical to a business of this nature,” remarked CGP’s Senior Vice President of Information Technology, Jim Milbery. “Furthermore, PRIMIS was able to utilize CGP’s relationships in the technology space to staff the long-term needs of the business.”

The sale of PRIMIS Marketing Group resulted in a return of approximately 3.5x CGP’s invested capital and an internal rate of return of 52%.  PRIMIS is the fifth exit out of the twenty-three investments made by CGP’s seventh fund.  Those exits have combined to return approximately 50% of the fund’s total called capital.
