Think Partnership Acquires Real Estate School Online Inc.
Accretive Merger Expected to Add Over $1.6 Million Annually to the Company’s Pre-Tax Income

NORTHBROOK, Ill. – July 18, 2005 – In a move that will make CGI Holding Corporation d/b/a Think Partnership Inc. (AMEX: THK; “Company”) a major player in the growing field of online education, the Company today announced that it has closed its acquisition of Real Estate School Online Inc. (“Real Estate School Online”).

Located in Miami, Fla., Real Estate School Online is a leading provider of online education products and services specializing in delivery of fully accredited real estate licensing and continuing education courses. Already an industry leader in Florida, Real Estate School Online has begun expanding its services to other states. Perry Johannesburg, the president of Real Estate School Online, will continue to serve in that capacity following the merger.

The Company has acquired all of the stock of Real Estate School Online in exchange for $2.2 million in cash and CGI common stock with an aggregate value of $2.2 million. Former shareholders of Real Estate School Online will also be entitled to a one-time cash payment of up to $500,000 if the pre-tax earnings of Real Estate School Online exceed specified targets during the first twelve full calendar quarters following the closing. The merger is expected to be immediately accretive to the earnings of Think Partnership.

Gerard M. Jacobs, the Company’s CEO, stated, “Real Estate School Online is a growing and highly profitable company with a very scalable business model.  While we plan to expand the Real Estate School Online services to other states, we expect Real Estate School Online to realize over $1.6 million of pre-tax income over the next twelve months without the benefit of our expansion plans or the leverage that the marketing power of other Think subsidiaries will provide. Perry Johannesburg is a very smart entrepreneur who is a great fit for our growing partnership.”

Scott Mitchell, the CEO of the Company’s Cherish subsidiary, added, “This merger is very much in line with Think Partnership’s strategy of bringing onboard companies that demonstrate consistent, strong performance and that offer unique approaches to online services. Perry Johannesburg’s vision and leadership will serve as great assets to the parent company and help assure continued growth and profitability.”

“Real Estate School Online has experienced tremendous growth of late and will one day have a national presence,” said Perry Johannesburg, president of Real Estate School Online. “Realizing synergies with the many Think Partnership companies will position us well to make that reality happen sooner than if we were going it alone. We fielded purchase offers from many suitors, but in the end Think Partnership was the best fit in terms of scope, expertise and complementary services.”

The Company has begun doing business under the name “Think Partnership Inc.” and will seek formal shareholder approval to change its legal name to Think Partnership Inc. later in 2005.
