The Debenture shall be converted immediately into shares of common stock of the Company following the closing of the merger transaction between the Company and ISO Block USA, A Colorado Corporation. Said stock shall be issued in such sums and amounts as has been received of the Principal Amount in accordance with the terms of Conversion provided in Section 4 of this Agreement. 19. REDEMPTION: (a) Redemption. If at any time after the Issue of this Debenture, an Event of Default occurs, the Company shall redeem at the option of the Holder of this Debenture, the outstanding principal amount of this Debenture. The "Redemption Price" is the total unpaid principal amount at the Redemption Date. (b) Notice of Redemption. The Holder may submit written notice of redemption, pursuant to paragraph (a) above, to the Company not less than (10) ten days prior to the date specified in the notice on which such redemption is to be made (the "Redemption Date"). In the case less than all the aggregate principal amount of the Debenture is redeemed, a new Debenture representing the aggregate principal amount of the unredeemed Debenture shall be issued to the Holder thereof without cost to such Holder within two (2) business days after the surrender of this Debenture. (c) Redemption Payments. For each Debenture or portion thereof which is to be redeemed hereunder, the Company shall be obligated on the applicable Redemption Date to pay to the Holder thereof (upon surrender by such Holder at the Company's principal office of the Debenture) the Redemption Price in cash or in immediately available funds. If the Company does not make the payment when due, interest will accrue on all outstanding Debentures from and after the Redemption Date at the Default Rate, the Conversion Price calculated pursuant to Section 4 in connection with any subsequent conversion of this Debenture will be reduced to $1.50 per share, and this Debenture shall be immediately convertible notwithstanding any other restrictions on conversion. (d) Interest After Redemption Date. If the Redemption Price of such Debenture is paid in full to the Holder of the Debenture on the Redemption Date, this Debenture shall not be entitled to any interest accruing after such date and on such date, all rights of the Holder of the Debenture shall cease, and the Debenture shall no longer be deemed to be issued and outstanding. 20. Conversion. Subject to and upon compliance with the provisions of the Debentures, at the option of the Holder thereof, the Debentures or any portion thereof and any accrued and unpaid interest thereon may be converted into fully paid and nonassessable shares (calculated as to the nearest number of whole shares) of the Company's Common Stock at the Conversion Price as defined herein (the "Conversion Shares"). The "Conversion Price" is $2.00 per share. The total number of shares of Common Stock into which Debenture may be converted will be determined by dividing the unpaid principal amount, plus accrued and unpaid interest thereon by the Conversion Price. No fractional shares will be issued upon conversion. The Conversion right expires when all of the Debentures have been paid in full, including accrued interest and costs of collection. In the case of any Debenture which is surrendered for conversion, accrued and unpaid interest will be payable on such Debenture with respect to the period ending on conversion date. Upon the occurrence of an Event of Default, all of the Debentures shall be immediately convertible notwithstanding any timing restrictions imposed herein. A. Exercise of Conversion Right. To exercise the conversion right, the Holder of the Debenture shall surrender to the Company such Debentures, duly endorsed, accompanied by written Notice of Conversion to the Company in the form provided in this Debenture that the Holder elects to convert such Debenture, or if less than the entire principal amount thereof is to be converted, the specified portion. Debentures shall be deemed to have been converted immediately prior to the close of business on the day of surrender of such Debentures for conversion in accordance with the foregoing provisions, and at such time the rights of the Holders of such Debentures as Holders shall cease, and the person or persons entitled to receive the Common Stock issuable upon conversion shall be treated for all purposes as the record holder or holders of such Common Stock as and after such time. Within two days after the conversion date, the Company, without cost to the Holder, shall issue and deliver to Holder the converted Debenture or the person, specified by such Holder, a certificate for the number of full shares of Common Stock issuable upon conversion registered in the name of such Holder or such other person as shall have been specified by such Holder and all accrued and unpaid interest on the converted Debenture or portion there upon which the Holder does not elect to receive payment in Common Stock. Upon Conversion of this Debenture, the Company shall take all such actions as are necessary in order to insure that the Common Stock issuable with respect to such conversion shall be validly issued, fully paid and nonassessable. The Company shall not close its books against the transfer of Common Stock issued or issuable upon conversion of this Debenture in any manner that interferes with the timely conversion of this Debenture. The Company shall assist and cooperate with any Holder of this Debenture required to make any governmental filings or obtain any governmental approval prior to or in connection with the conversion of this Debenture (including, without limitation, making any filings required to be made by the Company). The conversion rights of any Debenture subject to redemption hereunder shall terminate on the Redemption Date for such Debenture unless the Company has failed to pay to Holder thereof the Redemption Price of such Debenture or portion thereof. B. Consolidation of Company. In the case of any consolidation or merger of the Company with or into another corporation (other than a consolidation or merger in which the Company is the surviving corporation and which does not result in any reclassification or change of outstanding shares of the class issuable upon conversion of the Debentures), or in case of any sale or transfer to another corporation of the property of the Company as an entirety or substantially as an entirety, the Holder of each Debenture, then outstanding shall have the right to exercise such Debenture for the purchase of the kind and amount of shares of Common Stock and other securities and property receivable upon such consolidation, merger, sale, or transfer by a holder of the number of shares of Common Stock which would have been issuable if the conversion of the Debentures had occurred immediately prior to such consolidation, merger, sale or transfer. 5. Registration Rights. The Company, at its sole cost and expense, covenants to register or qualify or cause to be registered or qualified by one or more registrations or qualifications under applicable federal and state securities laws the sale and resale by the Holder of all the Conversion Shares and all of the additional shares of Common Stock issued or issuable to the Holder pursuant to this Debenture, if any, (the "Registrable Securities"), and to maintain such registrations or qualifications effective for all periods during which any portion of any Debenture may be converted. The Company covenants to use its best efforts to cause such registrations or qualifications to become effective as soon after filing as possible and to remain effective for all periods during which any portion of any Debenture may be converted. The Company covenants to prepare and file with the Securities and Exchange Commission such amendments and supplements to such registrations or qualification and the prospectus used in connection therewith as may be necessary to keep such registrations or qualifications effective and to comply with the provisions of the Securities Act of 1933, as amended, respect to the disposition of all securities covered by such registration or qualification in accordance with the intended methods of disposition by the Holder thereof set forth in such registration or qualification. 6. Piggyback Registration. If Company, at any time or times proposes or is required to register any of its Common Stock or other equity securities for public sale for cash under the Securities Act (other than on Forms S-4 or S-8 or successor forms thereto or any form on which the Registrable Securities are not eligible to be registered), and any applicable state securities law, it will at each such time or times give written notice to the Holder of its intention to do so. Upon the written request of Holder given within fifteen (15) days after receipt of any such notice, Company shall use its best efforts to cause the registration of Holder's conversion shares pursuant to the Securities Act and any applicable state securities laws; provided, that if the Piggyback Registration involves a public offering and the underwriters thereof advise Company in writing that in their opinion the Conversion Shares proposed to be registered in such Piggyback Registration should be offered for sale so as not to materially and adversely affect the price or salability of the stock being registered by Company, then the Holders proposing to include conversion shares in the registration statement, other than pursuant to the exercise of demand rights or piggyback rights, shall reduce on a pro rata basis the number of Conversion Shares to be included in the registration statement. 7. Holder's Investment Representation. Holder understands that the purchase and sale of the subject Debentures have not been registered under the Securities Act or applicable state securities laws on the basis that the purchase and sale of the Dentures are exempt from such registration under the Securities Act and Securities Laws based in part upon the representations made herein. Holder, thereby, represents that he does not intend to resell or otherwise dispose of the shares being purchased and sold hereby. Holder, further represents that he is acquiring the Debentures for investment purposes only and for his own account, not on behalf of others, and not with a view to resell or otherwise to distribute the purchased shares, and the Holder will not sell or otherwise distribute the purchased shares without registration under the Securities Act and applicable Securities Laws or pursuant to applicable exceptions therefrom. The Holder represents that he will not attempt to sell or otherwise distribute his Debentures, except in compliance with the anti-fraud, registration and any of the material provisions of the Securities Act and applicable Securities Law. A legend will be placed on the certificate evidencing the Debenture to the effect that such shares have not been registered under the Securities Act or applicable Securities Laws and that the Purchased Shares may not be resold unless they are registered under the Securities Act and Securities Laws or pursuant to applicable exemptions therefrom. 8. Representations, Warranties and Covenants. The Company hereby represents, warrants and covenants as follows: A. Reservation of Common Stock. The Company shall at all times reserve and keep available, free from preemptive rights, out of its authorized but unissued Common Stock or out of the Common Stock held in treasury, the full number of shares of Common Stock as shall from time to time be issuable upon the conversion of all issued and outstanding Debentures. B. Covenant as to Common Stock. The Company covenants that all shares of Common Stock which may be issued upon conversion of Debentures, including interest, additional shares of Common Stock and penalties, will upon issue be fully paid and nonassessable and the Company will pay all taxes, liens and charges that may be payable in respect of the issue or delivery of shares of Common Stock on conversion of Debentures pursuant hereto.
