In addition, funds affiliated with Oak Hill Capital own approximately 20.5 million converted common shares and GI Partners owns approximately 2.5 million of the converted common shares.

The converted common shares have not been registered under the Securities Act of 1933, and therefore may not be sold unless registered or pursuant to an exemption from registration.
