The Issuer shall pay all expenses of registration (other than underwriting fees and discounts in respect of shares of Common Stock offered and sold under such registration statement by the Purchaser, if any). (2) If the Registration Statement is not declared effective by the Commission during the 120-day period mentioned above, the Company shall pay in cash (or common stock valued at Market Price, as hereinafter defined) to the Purchaser, as liquidated damages and not as a penalty, an amount equal to two percent (2%) per month (commencing 90 and ending 120 days after the initial Closing) of the outstanding principal amount of the Debentures, in the event that the Registration Statement is not declared effective by the Commission within 90 days of the initial Closing Date and three percent (3%) from 120 days after the Closing Date until the Registration Statement is declared effective. 7. Transfer Agent Instructions, Book-Entry System, Liquidated Damages. Each conversion of the Debentures and/or exercise of the Warrants will be effected through a "book-entry" mechanism.

If the Company willfully fails to deliver shares of Common Stock without restrictive legends or stop-transfer orders within four (4) New York Stock Exchange Trading Days of delivery of a notice of conversion following the effectiveness of the Registration Statement, or fails to deliver legended certificates if requested prior thereto, liquidated damages will accrue in an amount equal to $1,000.00 for each $100,000.00 principal amount of Debentures as to which conversion has been requested then outstanding for each day that such shares of Common Stock are not delivered up to 10 days, and $2,000.00 for each $100,000.00 principal amount of Debentures as to which conversion has been requested then outstanding for each day that such shares of Common Stock are not delivered in excess of 10 days. Such amounts will accrue and be payable to the Purchaser by the Issuer upon demand notices of conversion shall be submitted by facsimile transmission and shall be deemed to have been received on the date transmitted. 8. Indemnification.

Closing Date. This agreement shall be effective from the date of execution by the Purchaser. Each Closing shall be effected through delivery of funds and certificates to the Escrow Agent. The Closing Date, which shall be so designated by a "Closing Certificate" from the Escrow Agent, shall be deemed to be that date upon which the Escrow Agent shall have the Securities available for delivery to the Purchaser and the Purchaser's funds in the Escrow Agent's account available for delivery to the Issuer. The Debentures will be issuable in five tranches of $2,000,000 each. The first tranche will close no later than April 15, 1997.

At any time after the effective date of the Registration Statement and prior to the funding of all tranches contemplated hereunder Issuer may give written notice (a "Funding Notice") to Purchaser that funding of a tranche is 10 11 requested. Funding of any tranche after the first is at the sole discretion of the Purchaser. If Purchaser shall elect not to fund such tranche by written notice to Issuer or by failing to effect a Closing within five days of receipt of a Funding Notice, and provided that such failure to is not the result of Issuer's inability or unwillingness to satisfy its obligations for such Closing, Issuer shall be free to sell any of its securities to any third party.
