Press Release - May 10, 2004 CDW•G Expands Small Business Consortium To Serve State, Local and Education Customers Program Now in More Than Eight States   Vernon Hills, Ill. - May 10, 2004 - CDW Government, Inc. (CDW•G), the government and education subsidiary of CDW Corporation (Nasdaq: CDWC), today announced it is expanding its Small Business Partner Consortium ("SBC") to serve state, local government and education customers in eight states: Connecticut, Florida, Georgia, Maryland, Michigan, New York, Virginia and Wisconsin. The SBC program has been in operation at the federal level since July 2003 and was launched at the state level in January 2004 in California, Illinois, Ohio, Texas and Washington. The CDW•G Small Business Partner Consortium was created to help small and disadvantaged businesses more effectively compete for federal and state information technology (IT) contracts. By partnering with CDW•G, participating companies are able to leverage CDW•G's operational efficiency, marketing reach, e-commerce and service capabilities. In addition, the program enables government agencies to meet minority-, veteran-, HUBZone-, and women-owned business purchasing goals. As an added benefit, government agencies that hire participants of SBC receive specialized IT services through CDW•G. "The Small Business Partner Consortium is a success for CDW•G, the participants and the government agencies," said Jim Shanks, president of CDW•G. "We see the expansion of the SBC as a positive signal to our state, local and education customers in these eight states that we are working to deliver innovative ways to solve their technology needs." One of the SBC's first participants was Sophisticated Systems, an Ohio-based systems integrator and hardware/software provider with offices in Columbus, Dayton, Indianapolis and Detroit. "As one of the first minority- or women-owned businesses to join CDW•G's Small Business Partner Consortium, we are honored to work with such an outstanding company that recognizes quality and puts its clients' needs first," said Dwight Smith, president and CEO of Sophisticated Systems. "Together, we are bidding and beginning to win business with CDW•G as a true partner. We see the value that the Consortium brings to our clients, both today and in the future." CDW•G will continue to roll out its SBC to other states through a phased process. "It is important that the SBC program is profitable for both CDW•G and our partners, so we are carefully managing our expansion efforts," said Kevin Adams, CDW•G vice president of program management. "As with all our new initiatives at CDW•G, we want to ensure that we always provide superior performance for our customers." How It Works Once selected as part of a competitive bidding process, Consortium members sign an annual CDW•G partnership contract that is not limited to any specific project. As the small businesses pursue an opportunity, they work directly with the customer and involve CDW•G when they need products to support their service engagements or when they want to offer their customers CDW•G's many value-adding offerings, such as custom PC configuration, asset-tagging services, and the CDW•G Software License Tracker -- a web-based software license management tool. CDW•G also refers business to member companies, and conducts sales and marketing activities with the Consortium members. On May 3, 2004, CDW•G issued a request-for-proposal (RFP) soliciting woman-, minority- or veteran-owned companies, certified small and disadvantaged firms, and companies located in a federal HUBZone in these eight states to participate in the SBC. The HUBZone program provides federal contracting assistance to businesses located in economically distressed geographic areas. The RFP can be found on CDW•G's Web site at www.cdwg.com/smallbizrfp. The deadline for submitting proposals is June 7, 2004, with the goal of having partnership agreements in place by July 1, 2004.
