2.01 Events of Default. The occurrence of any one or more of the following events shall constitute an “Event of Default”:

	(a)		failure to make payment on or before the date any payment of principal or interest is due hereunder, and such default shall continue for a period of ten (10) days after written notice from Holder to the Company thereof; or
	(b)		failure to perform or observe any other covenant, promise or agreement contained herein within thirty (30) days after written notice from Holder to the Company (or such longer period as shall be reasonably necessary to cure such failure provided the Company promptly commences such cure within said thirty (30) day period and thereafter diligently pursues such cure to completion); or
	(c)		the Company dissolves, adopts or carries out a plan of liquidation, sells in bulk any of its assets pursuant to a plan of liquidating its business, or redeems or acquires any of its outstanding stock (other than common stock or options acquired from employees or directors upon the termination of their relationship with the Company); or
	(d)		the Company becomes insolvent or makes an assignment for the benefit of its creditors; or
	(e)		the Company files (or consents to the filing) of any petition or complaint pursuant to federal or state bankruptcy or insolvency laws seeking the appointment of a receiver or trustee for any of its assets, seeking the adjudication of the Company as a bankrupt or insolvent, seeking an “order for relief” under such statutes, or seeking a reorganization of or a plan of arrangement

for the Company; or (b) any such petition is filed concerning the Company or any of its assets and is not dismissed within thirty (30) days after the filing thereof.

2.02 Acceleration of Maturity. If an Event of Default occurs, then upon the written notice of Holder in the case of an Event of Default under Sections 2.01(a), (b) or (c) above, and without any action taken by Holder in the case of an Event of Default under Sections 2.01(d) or (e) above, the entire principal balance under this Debenture, together with interest accrued thereon and all other Amounts Payable (including all sums expended by Holder in connection with such Event of Default), shall become immediately due and payable.

2.03 Default Interest Rate. While any Event of Default exists, interest on the unpaid principal balance of the Debenture from time to time and any other amounts due hereunder shall accrue at a rate per annum (“Default Interest Rate”) equal to fifteen percent (15%), and the Company shall pay such interest upon demand, or if no such demand is made, then at the times payments of interest and/or principal are due as provided herein. All unpaid interest that has accrued under this Debenture, whether prior (at the Interest Rate) or subsequent (at the Default Interest Rate) to the occurrence of the Event of Default, shall be paid at the time of, and as a condition precedent to, the curing of the Event of Default.

2.04 Attorneys’ Fees. If any counsel is employed, retained or engaged (a) upon the occurrence of an Event of Default, to collect the Amounts Payable or any part thereof, whether or not legal proceedings are instituted by Holder, (b) to represent Holder in any bankruptcy, reorganization, receivership, or other proceedings affecting creditors’ rights and involving the Company or a claim under this Debenture, or (c) to represent Holder in any other proceedings in connection with this Debenture, then the Company shall pay on demand to Holder all related reasonable attorneys’ fees and expenses as a part of the Amounts Payable.

2.05 Holder’s Remedies. Upon the occurrence of an Event of Default, Holder, at its option, may proceed to exercise any other rights and remedies available to Holder under this Debenture and to exercise any other rights and remedies against the Company or with respect to this Debenture which Holder may have at law, at equity or otherwise. Holder’s remedies under this Debenture shall be cumulative and concurrent and may be pursued singly, successively, or together against the Company. Holder may resort to every other right or remedy available at law or in equity without first exhausting the rights and remedies contained herein, all in Holder’s sole discretion. Failure of Holder, for any period of time or on more than one occasion, to exercise its option to accelerate the Maturity Date shall not constitute a waiver of that right at any time during the Event of Default or in the event of any subsequent Event of Default. Holder shall not by any other omission or act be deemed to waive any of its rights or remedies unless such waiver is written and signed by an officer of Holder, and then only to the extent specifically set forth. A waiver in connection with one event shall not be construed as continuing or as a bar to or waiver of any right or remedy in connection with a subsequent event.

ARTICLE III. SUBORDINATION

3.01 Amounts Payable Subordinated to Senior Indebtedness. Notwithstanding any provision of this Debenture to the contrary, the Company covenants and agrees, and the Holder by acceptance of this Debenture likewise covenants and agrees, that all Amounts Payable shall be subordinated to the prior payment in full of the Senior Indebtedness (defined below), in cash or cash equivalents satisfactory to the holders of such Senior Indebtedness, as those terms are defined below.

     3.02 “Senior Indebtedness” means the principal of, premium (if any), and interest on Indebtedness of the Company outstanding at any time created, whether absolute or contingent, direct or indirect and howsoever evidenced, including but not limited to all pre-petition and post-petition interest thereon, fees,

expenses and all other sums for which the Company may now or at any time or times hereafter be liable under any agreement, instrument or document which by its terms is superior in right of payment to this Debenture.

3.03 “Indebtedness” means (a) any debt of the Company (i) for borrowed money, capitalized lease obligations or purchase money obligations; or (ii) evidenced by a note, debenture, letter of credit or similar instrument given in connection with the acquisition, other than in the ordinary course of business, of any property or assets; (b) any debt of others described in the preceding clause which the Company has guaranteed or for which it is otherwise liable; and (c) any amendment, renewal, extension or refunding of any such debt.

3.04 Payments of Amounts Payable.

	(a)		So long as there is no event of default on any Senior Indebtedness of the Company (as such default may be defined therein), the Company shall make payments of interest only on the unpaid principal amount hereof to the Holder pursuant to Section 1.02 above.
	(b)		Upon the happening of any default on any Senior Indebtedness, then, unless and until such default shall have been cured or waived or shall have ceased to exist, the Company shall not make any payment with respect to the principal of, premium, if any, or interest on this Debenture nor shall the Company make any payment of any damages, fees, expenses or any other amounts in respect of this Debenture. Nothing in this Section 3.04, however, shall relieve the holders of such Senior Indebtedness or their representative(s) from any notice requirements set forth in the instrument evidencing such Senior Indebtedness.
	(c)		In the event that notwithstanding the provisions of this Section 3.04 the Company shall make any payment to the Holder on account of the principal of or interest on this Debenture, after the happening of a default on Senior Indebtedness, then, unless and until such default shall have been cured or waived or shall have ceased to exist, such payment shall be held by the Holder, in trust for the benefit of, and shall be paid forthwith over and delivered to, the holders of Senior Indebtedness (pro rata as to each of such holders on the basis of the respective amounts of Senior Indebtedness held by them) or their representative(s) or the trustee(s) under the indenture or other agreement (if any) pursuant to which Senior Indebtedness may have been issued, as their respective interest may appear, for application to the payment of all Senior Indebtedness remaining unpaid to the extent necessary to pay all Senior Indebtedness in full in accordance with its terms, after giving effect to any concurrent payment or distribution to or for the holders of Senior Indebtedness.
	(d)		The Company shall give prompt written notice to the Holder of any default on any Senior Indebtedness.
