Onstream Media Signs MarketPlace365 Services Agreement with Sidoti & Company, LLC to Showcase Micro-Cap Companies

POMPANO BEACH, FL – June 6, 2011 - Onstream Media Corporation ( OTC: ONSM), a leading online service provider of live and on-demand corporate audio and web communications, virtual event technology, and social media marketing, today announced that Sidoti & Company, LLC has signed a MarketPlace365 services agreement to develop a virtual tradeshow, which Sidoti expects to keep nearly 600 micro-cap and small-cap opportunities squarely in the eye of potential investors. New York City-based Sidoti is a preeminent provider of institutional-quality equity research, and the services agreement with MarketPlace365 offers the small- and micro-cap companies Sidoti investigates a chance to tell their story to investors -- the products and services they provide, how they differ from rivals, and especially what makes them attractive investments. The companies and their investor audiences will be able to network virtually.

Sidoti & Company is well-known as Wall Street's "axe" on small- and micro-cap companies, which are finally gaining the attention the firm has long argued these names deserve. In existence for ten and a half years, Sidoti has grown from five analysts to nearly 60, all dedicated to educating Wall Street on the merits of these two groups, whose market capitalizations are under $3 billion and $200 million, respectively. While profitable and promising, many small- and micro-cap names are unknown to investors because Sidoti's bulge-bracket research competitors neglect them. Sidoti covers nearly 600 small- and micro-cap companies, including 1-800 Flowers, Diebold, Domino's, Earthlink, Lennox, Fair Isaac, Kelly Services and NCR, and maintains that the two groups are rife with unmined investment gems.

Sidoti is also highly regarded for the annual Small-Cap and Micro-Cap Investor Forums it hosts in New York City, which attract hundreds of savvy investors, as well as for the nearly 1,000 non-deal road show days the firm offers its institutional client base each year.

Now Sidoti & Company is excited to see how far MarketPlace365 can extend its reach and enhance its capabilities. The firm expects the cornerstone of the marketplace will be the "exhibit hall," which will showcase hundreds of the companies it covers to the investment community, using MarketPlace365's comprehensive multimedia tools. The Sidoti virtual marketplace will host dedicated client "exhibit booths" with robust market intelligence and company-specific presentations including everything from breaking news, corporate videos, and social media news feeds to intraday stock charts and quotes, corporate blogs, investor presentations, Web TV telecasts and more. The firm's goal is to provide an online platform to increase visibility and investor awareness of exhibiting companies, along with the most user-friendly, interactive tools available for investors to access this information.

In addition, the online media library will include valuable archived information, the virtual auditorium will provide a stage where little-known but fine companies can "strut their stuff" to a wide audience of potential investors, and the web-based learning center will include breakout sessions and a continuing education area devoted to latest developments at companies Sidoti thinks deserve investors' keen attention.

"Perhaps no other industry relies on networking as much as the small- and micro-cap investment community," said Randy Selman, President and CEO of Onstream Media. "MarketPlace365's presentation and social networking capabilities are designed to stimulate business activity, interaction and thought leadership knowledge sharing by providing an online forum to facilitate discussions with management, investors and other industry professionals."
