Prepayment. The Company may prepay any portion or all of the principal balance or interest of this Bond upon ten (10) days' prior written notice. Any prepayment of this Bond will be credited first against accrued interest then principal. 4. Conversion. a. Holder's Conversion Rights. So long as any principal remains outstanding hereunder up to and through the Due Date (the "Conversion Period"), Holder may, at its option by written notice to the Company, convert all or any part of the principal and interest due hereunder in increments of $100,000 or more (or such lesser amount as may remain outstanding under this Bond at the time of conversion) into Common Stock of the Company at Thirty Cents ($0.30) per share. b. General Conversion Terms. Upon Holder's election to convert this Bond, the applicable amount of outstanding principal and interest of this Bond shall be converted so long as such conversion is exempt from applicable state and federal registration requirements and the terms and conditions set forth below. The Company shall not be obligated to issue certificates evidencing the shares of the securities issuable upon such conversion unless this Bond is either delivered to the Company or its transfer agent, or the Holder notifies the Company or its transfer agent that such Bond has been lost, stolen or destroyed and executes an agreement and provides collateral satisfactory to the Company to indemnify the Company from any loss incurred by it in connection with such Bond. The Company shall, as soon as practicable after such delivery, or such agreement and indemnification, issue and deliver at such office to such Holder of such Bond, a certificate or certificates for the securities to which the Holder shall be entitled accompanied by appropriate restrictive legends on transfer, a check payable to the Holder in the amount of any cash amounts payable as the result of a conversion into fractional shares of Common Stock, as the case may be, and a new Bond upon the same terms this Bond for any remaining principal in the case of a conversion of only a portion of this Bond. Such conversion shall be deemed to have been made immediately prior to the close of business of the date of receipt of written notice by the Company causing conversion.

If the Company at any time during the Conversion Period shall, by subdivision, combination or re-classification of securities, change any of the Company's Common Stock to which purchase rights under this Bond exist into the same or different 21 number of securities of any class or classes, this Bond shall thereafter entitle the Holder to acquire such number and kind of securities as would have been issuable as a result of such change with respect to the shares hereunder immediately prior to such subdivision, combination, or re-classification. If shares of the Company's Common Stock are subdivided into a greater number of shares of Common Stock, the conversion price for the shares hereunder upon conversion of this Bond shall be proportionately reduced and such shares be proportionately increased; and conversely, if shares of the Company's Common Stock are combined into a smaller number of Common Stock shares, the price shall be proportionately increased, and the Common Stock shares hereunder shall be proportionately decreased. 8.
