or oral request of a holder of Series B Preferred Stock, the Corporation shall within one (1) business day confirm orally and
in writing to such holder the number of shares of Common Stock then outstanding. In any case, the number of outstanding shares
of Common Stock shall be determined after giving effect to the conversion or exercise of securities of the Corporation, including
shares of Series B Preferred Stock, held by such holder and its affiliates since the date as of which such number of outstanding
shares of Common Stock was reported, which in any event are convertible or exercisable, as the case may be, into shares of the
Corporation&rsquo;s Common Stock within sixty (60) days&rsquo; of such calculation and which are not subject to a limitation on
conversion or exercise analogous to the limitation contained herein. The provisions of this paragraph shall be construed and implemented
in a manner otherwise than in strict conformity with the terms of this Section 5 to correct this paragraph (or any portion hereof)
which may be defective or inconsistent with the intended beneficial ownership limitations herein contained or to make changes
or supplements necessary or desirable to properly give effect to such limitation.</TD>
