or (B) if requested by the Investor on the signature page hereto or if the Company is unable to make the delivery through the facilities
of The Depository Trust Company’s DWAC system, through the book-entry delivery of Shares on the books and records of the
transfer agent. 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
