This Debenture has been entered into pursuant to the terms of the Joint Management Agreement among the Company, the Holder and others. The following terms shall apply to this Debenture: ARTICLE I CONVERSION RIGHTS 1.1 Conversion. The Holder is entitled, at its option, to convert all or any part of the principal amount of the Debenture, plus accrued interest, into shares (the "Conversion Shares") of the Company's common stock, no par value ("Common Stock"), at the price per share (the "Conversion Price") equal to the average of the closing bid prices of the Company's Common Stock, as quoted by Bloomberg, LP, for the five (5) trading days immediately preceding the Conversion Date (as defined herein). No fraction of shares or scrip representing fractions of shares will be issued on conversion, but the number of shares issuable shall be rounded to the nearest whole share. To convert this Debenture, the Holder hereof shall deliver written notice thereof, substantially in the form of Exhibit "A" to this Debenture, with appropriate insertions (the "Conversion Notice"), to the Company at its address as set forth herein. The date upon which the conversion shall be effective (the "Conversion Date") shall be deemed to be the date set forth in the Conversion Notice. 1.2 Adjustments. The number and kind of shares or other securities to be issued upon conversion determined pursuant to Section 1.1 shall be subject to adjustment from time to time upon the happening of certain events while this conversion right remains outstanding, as follows: A. Merger, Sale of Assets, etc. If the Company at any time shall consolidate with or merge into or sell or convey all or substantially all its assets to any other corporation, the conversion right in this Debenture, as to the unpaid principal portion thereof and accrued interest thereon, shall thereafter be deemed to evidence the right to purchase such number and kind of shares or other securities and property as would have been issuable or distributable on account of such consolidation, merger, sale or conveyance, upon or with respect to the securities subject to the conversion or purchase right immediately prior to such consolidation, merger, sale or conveyance. The foregoing provision shall similarly apply to successive transactions of a similar nature by any such successor or purchaser. B. Reclassification, etc. If the Company at any time shall, by reclassification or otherwise, change the Common Stock into the same or a different number of securities of any class or classes, this Debenture, as to the unpaid principal portion thereof and accrued interest thereon, shall thereafter be deemed to evidence the right to purchase an adjusted number of such securities and kind of securities as would have been issuable as the result of such change with respect to the Common Stock immediately prior to such reclassification or other change. 1.3 Reservation of Shares. During the period the conversion right exists, Company will reserve from its authorized and unissued Common Stock 150% of the number of shares of Common Stock issuable upon the full conversion of this Debenture. Company represents that, upon issuance, such shares will be duly and validly issued, fully paid and non-assessable. Company agrees that its issuance of this Debenture shall constitute full authority to its officers, agents, and transfer agents who are charged with the duty of executing and issuing stock certificates to execute and issue the necessary certificates for shares of Common Stock upon the conversion of this Debenture. 1.4 Maximum Conversion. The aggregate conversion of principal pursuant to this Article I shall not at any time exceed the Conversion Limit, except that the Conversion Limit may be exceeded at any time when an Event of Default has occurred and is continuing. The "Conversion Limit" will equal the product of the principal amount of this Debenture recited on its first page multiplied by a fraction, the numerator of which is the number of months including and after the month in which the Effective Date occurs, and the denominator of which is thirty-six (36). The "Effective Date" will be date on which the Securities and Exchange Commission declares effective the Registration Statement filed pursuant to the Joint Management Agreement.
