"Acxiom" looks interesting. They are/were up to provide the software for Poindexter/DARPA's "Total Information Awareness" system. Just put "darpa acxiom" in a search engine.
Here's some more.
http://public.thecorporatelibrary.net/Transactions/rel_ACXM_2003.html "...During the past fiscal year we had an agreement with an affiliate of Stephens Group, Inc. ("Stephens"), whereby we retained the consulting services of a former Stephens employee who is also one of our board members, General Wesley K. Clark, in connection with our pursuit of contracts with various government agencies. Under the agreement, commissions were payable to the Stephens affiliate on revenue from government contracts attributable to Clark's efforts, which commissions were to be offset against an annual consulting fee of $300,000. As of March 1, 2003, General Wesley K. Clark resigned from Stephens and founded Wesley K. Clark & Associates, a business services and development firm. As of that date we replaced the agreement with the Stephens affiliate with an agreement with Wesley K. Clark & Associates for the consulting services of General Clark. Under the terms of the new agreement, Acxiom will pay Clark an annual retainer of $150,000 plus commissions for new business obtained through Clark's efforts, which commissions will be offset against the retainer.
