Exchange agreement, description
The Company granted Hillair the right to exchange 1,850 of the Company’ s Series 2 Convertible Preferred Stock (the “Preferred Shares”) for up to an aggregate of 5,606,061 shares (the “Exchange Shares”) of the Company’ s common stock. Pursuant to the Exchange Agreement, for so long as the Preferred Shares remain outstanding, each outstanding Preferred Share may be exchanged for the number of Exchange Shares equal to the quotient obtained by dividing $1,000 by $0.33. The exchange of the Preferred Shares will not be effected if, after giving effect to the exchange Hillair, together with its affiliates, would beneficially own in excess of 4.99% of the number of shares of the Company’s common stock outstanding immediately after giving effect to the issuance of the Exchange Shares. Upon not less than 61 days’ prior notice to the Company, Hillair may increase or decrease the ownership limitation, provided that the ownership limitation in no event exceeds 9.99% of the number of shares of the Company’s common stock outstanding immediately after giving effect to the issuance of the Exchange Shares.
