Interest, Conversion Rate and Prepayments XCEL Management, Inc., (the "Company"), a Utah corporation, promises to pay to the Holder named above the principal amount shown above, and interest on the principal amount of this Debenture, which interest is payable only in shares of the Company's Common Stock, $0.001 par value ("Common Stock") at a conversion rate of $1.42 per share) at the rate per annum shown above. The Company will pay accrued interest on the outstanding principal amount once annually commencing at the end of one (1) year from the date of issuance shown above and will pay the entire outstanding principal amount at the end of two (2) years from the date of issuance shown above ("Due Date"). Interest on the Debenture will accrue from the date of issuance. Interest will be computed on the basis of a 365-day year. The Company shall be entitled to pre-pay the amounts outstanding under this Debenture, in whole or in part, without penalty. 2. Method of Payment The Company will pay principal and interest on the Debenture to the person who is registered as the Holder of Debenture at the close of business on the Due Date. Holder must surrender the Debenture to the Company to collect the principal payment. The Company will pay principal in money of the United States that at the time of payment is legal tender for payment of public and private debts. However, the Company may pay principal by check payable in such money. It may mail said check to a Holder's address as shown on the books and records of the Company at that time. 3. Conversion A holder of a Debenture may convert it into Common Stock of the Company at any time on or after November 1, 2000 ("Conversion Date") and before the close of business on the Due Date. The initial conversion price is $1.42 per share. To determine the number of shares issuable upon conversion of a Debenture, the principal amount to be converted shall be divided by the conversion price in effect on the conversion date. On conversion, the outstanding principal amount will be adjusted hereunder and interest will continue to accrue only on such amount. The Company will deliver a check for any fractional share. To convert, a Debenture Holder must (1) complete and sign the conversion notice attached to this Debenture, (2) surrender the Debenture to the Company, (3) furnish appropriate endorsements and transfer documents if required by the Company, and (4) pay any transfer or similar tax if required. A holder may convert a portion of a Debenture if the portion is $10,000 or a whole multiple of $10,000. The conversion price will be adjusted for stock dividends, mergers, consolidations, stock splits or distributions on Common Stock; subdivisions, combinations or certain reclassifications of Common Stock; distribution to all holders of Common Stock of certain rights to purchase such Common Stock at less than the current market price at the time; distributions to such holders of assets or debt of the Company or certain rights to purchase debt of the Company (excluding cash dividends or distributions from current retained earnings). If the Company is a party to a consolidation or merger or a transfer or lease of all or substantially all of its assets, the right to convert a Debenture into Company Common stock may be changed into a right to convert it into stock, debentures, cash or other assets of the Company or of the entity resulting or surviving such merger or to which such assets shall have been sold, leased or transferred. If the Company completes its contemplated reorganization pursuant to which each holder of Common Stock will receive two (2) shares of common stock in a newly formed Delaware entity for every one (1) share of Common Stock held in the Company, the conversion price hereunder will automatically be adjusted to $0.71 on and after such reorganization. 2 4. Denominations, Transfer, Exchange The transfer of the Debenture must be registered with the Company or a Trustee. The Company may require a Holder, among other things, to furnish appropriate endorsements and transfer documents and to pay transfer taxes and fees required by law, if any. 5. Persons Deemed Owners The registered holder of a Debenture may be treated as its owner for all purposes. 6. Successor Corporation When a successor corporation assumes all the obligations of its predecessor under the Debenture, the predecessor corporation will be released from those obligations. 7. Registration Rights The Holders of this Debenture have been granted certain registration rights as set forth the Subscription Agreement between the Holder and the Company of even date herewith, and such Subscription Agreement shall be deemed to be incorporated by reference herein. The Holders shall be entitled to exercise such registration rights prior to the Conversion Date as set forth in the Subscription Agreement. 8. Defaults and Remedies An Event of Default is: default in payment of interest or principal on the Debenture; failure by the Company for thirty (30) days after notice to it to comply with any of its other agreements in the Debenture; the making of an assignment for the benefit of the Company's creditors; the filing of a voluntary or involuntary petition for or the appointment of a receiver of the Company's property; the filing of a voluntary petition by or an involuntary petition against the Company under any provision of the federal Bankruptcy Act; the dissolution of the Company's business. If an Event of Default occurs and is continuing, the Holder may declare the Debenture to be due and payable immediately. 9. No Recourse Against Others A director, officer, employee, agent or stockholder, as such, of the Company shall not have any liability for any obligations of the Company 3 under the Debenture or for any claim based on, in respect of, or by reason of such obligations or their creation. The Debenture Holder, by accepting this Debenture, waives and releases all such liability. The waiver and release are part of the consideration for the issue of the Debenture. 10. Authentication The Debenture shall not be valid until authenticated by the manual signature of an officer of the Company. 11.
