In the case of each of the Warrants, the warrant amounts are in addition to the 911,294 outstanding shares of Common Stock issued to LPC Fund and referred to in clause (i) above and are subject to a 9.99% beneficial ownership cap that prohibits the issuance of shares of Common Stock upon exercise of any Warrants to the extent such issuance would cause the holder’s beneficial ownership of Common Stock (as calculated pursuant to Section 13(d) of the Act and Rule 13d-3 promulgated thereunder) to exceed 9.99% of the outstanding Common Stock.

The Warrants each include a customary “cashless” exercise provision, which may be used to acquire underlying shares of Common Stock if at the time of exercise an effective registration statement registering the resale of such shares under the Act is not available to the warrant holder.

LPC is the Managing Member of LPC Fund. RCC and Alex Noah are the Managing Members of LPC. Mr. Scheinfeld is the president and sole shareholder of RCC, as well as a principal of LPC. Mr. Cope is the president and sole shareholder of Alex Noah, as well as a principal of LPC. As a result of the foregoing, Mr. Scheinfeld and Mr. Cope have shared voting and shared investment power over the shares of Common Stock of the Issuer held directly by LPC Fund.
