TOPIC:         "The Money Hunt: Navigating Today's Private Capital
               Marketplace"

DESCRIPTION:   It's a paradox: The private capital markets are
               managing record levels of money, and yet obtaining
               financing is as confusing and frustrating for
               entrepreneurs as ever. This discussion will help the
               CEOs of fast-growing companies better understand their
               options. What kinds of companies are raising money?
               What size are the deals getting done? How much capital
               can you reasonably ask for at this stage in your
               growth? What are the terms you should keep an eye out
               for? A panel of venture capitalists, CEOs, and angel
               investors who have worked with growth companies in the
               past will answer all of your questions.

ABOUT THE 24th ANNUAL INC. 500 CONFERENCE

In 1982, Inc. published the first Inc. 500 list honoring the 500 fastest-growing private companies. In that same year, Inc. launched the first Inc. 500 conference in Lexington, Kentucky. The conference was designed to recognize remarkable achievements of the Inc. 500 winners. Over the years, the event has evolved into an exclusive gathering where past and present winners come to learn, network, exchange ideas and celebrate. The event offers educational sessions, rousing keynotes, special events and getaway tours that boast a local flavor. Past session topics have included finance, human resources, leadership, marketing, technology, and management. The Conference culminates in a Black Tie Dinner in which all current year winners are recognized.
