              is
                not subject to back up withholding either because he, she or it has

                been notified by the Internal Revenue Service (“IRS”) that he, she or it
                is subject to backup withholding as a result of a failure to report
                all
                interest or dividends, or the IRS has notified him, her or it that
                he is
                no longer subject to backup withholding (Note this clause (q) should
                be

                will
                allow SIBE and its successors and assigns to pursue the Subscriber
                for
                payment of the amount due thereon by any legal means, including,
                but not
                limited to, acquisition of a judgment against the Subscriber in the
                event
                that the Subscriber defaults on the Promissory Note and Security
                Agreement; and
