25. CONVERSION RIGHTS.  Subject to prior payment or conversion in full of this Note, all or any portion of the Note shall, at the election of the Holder or at the election of the Company made at any time after issuance, convert automatically into a number of shares of common stock of the Company (the “Conversion Shares”) which is determined by dividing (a) the Purchase Amount plus any accrued and unpaid interest plus the accrued pro rata Discount outstanding and to be converted on the date of conversion by (b) the conversion price of $0.30 per share of common stock (the “Conversion Price”).  Conversion under this Section 25 shall occur following written notice by the Company given to the Holder, or by the Holder to the Company, as applicable, in the manner provided in Section 20, at which time the Holder shall endorse and surrender this Note for conversion at the principal offices of the Company and execute and deliver to the Company the forms of stock purchase agreement, investors’ rights agreement, right of first refusal and co-sale agreement, voting agreement, and other agreements and related documents as are requested by the Company, containing terms, conditions, limitations and restrictions customarily entered into in similar financings.  Notwithstanding the foregoing, conversion of this Note hereunder will be effective on the date of the Company’s notice of conversion whether or not the Holder endorses this Note and delivers it to the Company for cancellation or executes and delivers the required financing agreements to the Company. Absent receipt by the Company of such items from the Holder, the Company will convert this Note into Conversion Shares on the terms set forth herein, but the Holder will not be entitled to receive the certificate for such Conversion Shares unless and until the Holder executes and delivers to the Company all items required under this Section 25.
