VKernelTM Secures $4.6 Million Series A Financing

Funding co-led by Hummer Winblad Venture Partners and Polaris Venture Partners

PORTSMOUTH, N.H., February 4, 2008 - VKernel Corporation, a provider of easy-to-use and
quick-to-deploy virtual appliances for managing virtual server environments, announced today the
company has raised $4.6 million in its initial institutional round of funding. The round was co-led
by Hummer Winblad Venture Partners and Polaris Venture Partners.
VKernel will use the funds to advance product development, increase sales, and expand market
awareness. Additionally, Mitchell Kertzman of Hummer Winblad and Dave Barrett of Polaris will
join VKernel's Board of Directors.

"The server virtualization market is growing explosively," said Mitchell Kertzman, managing
director at Hummer Winblad. "This has us very excited about VKernel's vision as it is providing
the essential tools for IT staffs to virtualize their environments faster, more cost-effectively, and
with greater confidence."

"We believe organizations will see VKernel technology as a vital component of successful
virtualization projects," stated Dave Barrett, general partner at Polaris Venture Partners. "The
company's executive team has a solid track record of growing businesses from the ground up,
and we fully anticipate VKernel will rapidly become a player in this market."
VKernel, first launched in January 2007, is building a suite of "plug-and-play" virtual appliances
designed to quickly solve real world systems management challenges as organizations migrate to
virtual server environments. VKernel's patent-pending Chargeback appliance is certified byVMware,
and enables IT groups to immediately solve today's critical pain points by providing cost
visibility into the resource consumption of each virtual machine, resource pool, host, or cluster.
"Organizations of all sizes are virtualizing their server farms, which is creating a new set of systems management
challenges," said Alex Bakman, founder and CEO of VKernel. "To be successful, IT groups need tools that address
their most pressing issues. Unlike traditional systems management products that are difficult to install,
learn, and use, VKernel is delivering tiny virtual appliances designed to solve specific issues."
