If delivery is made by book entry on the books and records of the transfer agent, the Company shall send written confirmation of such delivery to the Investor at the address indicated on the Signature Page hereof. No fractional Shares shall be purchased and any excess funds representing fractional Shares shall be returned to the Investor. By payment of the Shares, the Investor acknowledges receipt of the Registration Statement and any amendment, the terms of which govern the investment in the Shares.
