CONVERSION PRIVILEGE. The registered holder hereof, if such registered holder is then an "accredited investor" as defined in Regulation D under the Securities Act of 1933 (an "Accredited Holder"), shall have the right to convert all or any part of the outstanding principal of this Note and interest accrued and unpaid hereon into shares of the Common Stock of the Company, at any time on or after March 31, 1997 (the "Exercisability Date") and prior to the Maturity Date, effective as of the close of business on the date this Note is duly delivered to the Company for such conversion, by delivering to the Company this Note 6 3 with the Notice of Conversion appended hereto appropriately dated and signed by the Accredited Holder. The number of shares of the Common Stock into which the principal of or interest on this Note may be converted shall be determined by dividing the aggregate amount of principal and interest so converted by the "Per Share Price" (defined below). Promptly after the effectiveness of such conversion, the Company shall issue to such Accredited Holder a certificate or certificates for the shares of Common Stock issued upon such conversion, which shares shall be validly issued, fully paid and nonassessable and free and clear of any liens, encumbrances or adverse claims, other than restrictions on transfer imposed by applicable securities laws. No fractional shares shall be issued upon such conversion, and in lieu of a fraction of a share, the Accredited Holder hereof shall receive cash in an amount equal to the amount of principal or interest that would otherwise have been converted into such fraction of a share. The Company shall reserve, for issuance upon the exercise of this conversion privilege, the number of shares of Common Stock issuable upon such conversion. The "Per Share Price" shall be $.40 per share of Common Stock. If during the period from the date hereof through the day next preceding the Exercisability Date the Company shall issue any shares of its Common Stock (other than pursuant to director or employee stock option plans) for cash to any purchaser who is not a director or officer of the Company or an affiliate or associate (as the terms "affiliate" and "associate" are defined in Rule 405 under the Securities Act of 1933) of such a director or officer (an "Unaffiliated Purchaser"), or shall issue any convertible debt securities to any Unaffiliated Purchaser that are convertible into shares of the Common Stock of the Company ("Convertible Securities"), and if, in conjunction with the issuance of shares of the Common Stock or Convertible Securities to an Unaffiliated Purchaser during such period, such Unaffiliated Purchaser also receives, as part of the investment unit that includes Common Stock or Convertible Securities, other securities of the Company or rights to purchase additional shares of the Common Stock or other securities, then at the request of the Accredited Holder hereof the Company shall negotiate in good faith with the Accredited Holder hereof for the sale of units comparable to those sold to Unaffiliated Purchasers and upon comparable terms to the extent of the amount of the outstanding principal of and interest on this Note, in lieu of the conversion privilege specified herein. If, in conjunction with the issuance of shares of the Common Stock or Convertible Securities to an Unaffiliated Purchaser during such period, such Unaffiliated Purchaser also receives registration rights with respect to the Common Stock acquired or to be acquired upon the exercise of conversion rights, the Company will negotiate in good faith to provide, to the extent practicable, comparable registration rights to the Accredited Holder hereof. The Company further agrees that, from the date hereof through the Maturity Date, it will not effect any stock split, stock dividend, or other division or combination affecting the outstanding Common Stock, or any other similar capital change, unless it shall have first offered to make appropriate equitable adjustment, reasonably satisfactory to the Accredited 7 4 Holder hereof, to the Per Share Price to appropriately and equitably take into account such capital change and its effect on this conversion privilege. Anything to the contrary herein notwithstanding, the Company shall not be obligated to issue any shares of the Common Stock upon the exercise of this conversion privilege if such issuance would be in violation of applicable securities laws. If the Company is so prevented from issuing such shares, it will use its best efforts to take appropriate action to permit such issuance in compliance with applicable securities laws as soon as practicable, provided it can do so without unreasonable effort or expense.
